Is Working Long Hours Raising Your Risk for Diabetes?

Women who work 45 hours or more each week may be upping their risk of diabetes, new research finds. Men who work the same number of hours, however, are not affected.

While prior research has suggested a link between a long work week and an increased risk of diabetes, most of these studies focused on men.  Interestingly, this recent research seems to find the opposite effect in males: the longer the work week, the lower the incidence of diabetes.

For women who work 45 hours per week or more, though, their risk was considerably higher.  When compared with women who work 35–40 hours each week, they had a 63 percent higher risk of developing diabetes.

The authors of the new study, which was published in BMJ Open Diabetes Research and Care, looked at data from the 2003 Canadian Community Health survey, which included respondents aged 35–74.

They also looked at the Ontario Health Insurance Plan database for physician services, as well as the Canadian Institute for Health Information Discharge Abstract Database for hospital admissions.

In all, over 7,000 Canadian employees were included in the research. As well as looking at hours worked, the researchers also included other factors in their analysis, such as: sex, marital status, parenthood, ethnicity, place of birth, place of residence, long-term health conditions, lifestyle, weight, and body mass index (BMI).

They also considered unique workplace factors, such as shift work and the type of job the respondents did — for instance, whether it was predominantly active or sedentary.

Overall, the risk of diabetes was “only slightly reduced” when factors such as smoking and alcohol levels were considered.

While the researchers could not establish a definitive cause and effect from these data, they note that encouraging women to work fewer hours may be a key component of reducing the number of diabetes cases.

The shape of diabetes

Diabetes is a widespread issue around the world and impacts many lives. When someone has diabetes, their body does not utilize insulin properly; the pancreas increases production of the hormone until it can no longer keep up with the body’s demands.

This leads to higher-than-normal blood glucose levels and can eventually cause a wide range of problems throughout the body.

The American Diabetes Association say that over 30 million people in the United States have diabetes, and 7 million of these individuals are unaware of it.

Diabetes remains the seventh leading cause of death in the U.S., and, each year, doctors discover 1.5 million new cases. Worldwide, this number jumps to 425 million adults, with half remaining undiagnosed.

Diabetes prevention and management, then, are an essential facet of public health. Studies such as this one can help doctors to create guidelines that can positively impact the health of their patients and lead to fewer cases of diabetes down the road.

Limitations and next steps

Although the records used in this study did not distinguish between type 1 and type 2 diabetes, it is estimated that type 1 diabetes accounts for around 5 percent of cases among those aged 18 or over, so most of these cases were likely to be type 2.

In the future, if further studies agree with these findings, healthcare providers may recommend that women work 40 hours per week or under.

The study authors write, “Considering the rapid and substantial increase of diabetes prevalence…worldwide, identifying modifiable risk factors such as long work hours is of major importance to improve prevention and orient policy making, as it could prevent numerous cases of diabetes and diabetes-related chronic diseases.”

Study Shows Food Restriction Prevents and Reverses Polycystic Kidney Disease in Mice

Researchers at Mayo Clinic have found that a mild to moderate reduction in calories effectively prevents and reverses polycystic kidney disease (PKD) in mice. The results appear online today in the Journal of the American Society of Nephrology.

“Currently, there is no FDA-approved treatment, and the only thing that can be done is dialysis or renal transplantation,” explains Eduardo Chini, M.D., Ph.D., anesthesiologist and researcher for Mayo Clinic’s Robert and Arlene Kogod Center on Aging and lead author of the study. “We have found that a very simple measure, like decreasing the amount of calories that are taken in, even by only 10 percent, can very significantly decrease the burden of this disease.”

How is Lack of Sleep Ruining Your Health?

I used to say, “I will sleep when I am dead.”  That’s Old military humor meant as some form of motivation in those days we would go for an eternity without sleep.  What I did not know was that not sleeping can draw us closer to death every day.

Ongoing surveys indicate more people are sleeping less than six hours a night, and sleep difficulties visit 75% of us at least a few nights per week. A short-lived bout of insomnia is generally nothing to worry about. The bigger concern is chronic sleep loss, which can contribute to health problems such as weight gain, high blood pressure, and a weakening in the immune system – all which can cause even greater problems down the road.

Why Is Sleep Important?

Sleep plays a vital role in good health and well-being throughout your life. Getting enough quality sleep at the right times can help protect your mental health, physical health, quality of life, and safety.

The way you feel while you’re awake depends in part on what happens while you’re sleeping. During sleep, your body is working to support healthy brain function and maintain your physical health. In children and teens, sleep also helps support growth and development.

Think of your body like a factory that performs a number of vital functions. As you drift off to sleep, your body begins its night-shift work:

  • Healing damaged cells
  • Boosting your immune system
  • Recovering from the day’s activities
  • Recharging your heart and cardiovascular system for the next day

Understanding the sleep cycle

Understanding what happens during sleep also means understanding the sleep cycle, which consists of  two recurring phases: REM (rapid eye movement) and NREM (non-REM or non-rapid eye movement). Both phases are important for different functions in our bodies.

NREM sleep typically occupies 75–80% of total sleep each night. Many of the health benefits of sleep take place during NREM sleep – tissue growth and repair occurs, energy is restored and hormones that are essential for growth and development are released.

REM sleep typically occupies 20–25% of total sleep each night. REM sleep, when dreaming occurs, is essential to our minds for processing and consolidating emotions, memories and stress. It is also thought to be vital for learning, stimulating the brain regions used in practicing and developing new skills.

If the REM and NREM cycles are interrupted multiple times throughout the night — either due to snoring, difficulties breathing or waking up frequently —we miss out on vital body processes.  This can affect our health and well-being the next day and long term.

What happens if you don’t get enough sleep?

If your body doesn’t get a chance to properly recharge – by cycling through REM and NREM – you’re already starting the next day at a disadvantage. You might find yourself:

  • Feeling drowsy, irritable or sometimes depressed
  • Struggling to take in new information at work, remembering things or making decisions
  • Craving more unhealthy foods, which could cause weight gain1

We have all heard about the importance of sleeping well, and we’ve all experienced the feeling of being refreshed after a good night’s sleep, or the feeling of fatigue after a poor night’s sleep. Even though we know this, in our busy society, many of us are not getting the quality sleep needed to truly receive its health benefits.

Here are a few reasons to catch more ZZZZs.

Healthy Brain Function and Emotional Well-Being

Sleep helps your brain work properly. While you’re sleeping, your brain is preparing for the next day. It’s forming new pathways to help you learn and remember information.

Studies show that a good night’s sleep improves learning. Whether you’re learning math, how to play the piano, how to perfect your golf swing, or how to drive a car, sleep helps enhance your learning and problem-solving skills. Sleep also helps you pay attention, make decisions, and be creative.

Studies also show that sleep deficiency alters activity in some parts of the brain. If you’re sleep deficient, you may have trouble making decisions, solving problems, controlling your emotions and behavior, and coping with change. Sleep deficiency also has been linked to depression, suicide, and risk-taking behavior.

Children and teens who are sleep deficient may have problems getting along with others. They may feel angry and impulsive, have mood swings, feel sad or depressed, or lack motivation. They also may have problems paying attention, and they may get lower grades and feel stressed.

Physical Health

Sleep plays a significant role in your physical health. For example, sleep is involved in healing and repair of your heart and blood vessels. Ongoing sleep deficiency is linked to an increased risk of heart disease, kidney disease, high blood pressure, diabetes, and stroke.

Sleep deficiency also increases the risk of obesity. For example, one study of teenagers showed that with each hour of sleep lost, the odds of becoming obese went up. Sleep deficiency increases the risk of obesity in other age groups as well.

Sleep helps maintain a healthy balance of the hormones that make you feel hungry (ghrelin) or full (leptin). When you don’t get enough sleep, your level of ghrelin goes up and your level of leptin goes down. This makes you feel hungrier than when you’re well-rested.

Sleep also affects how your body reacts to insulin, the hormone that controls your blood glucose (sugar) level. Sleep deficiency results in a higher than normal blood sugar level, which may increase your risk for diabetes.

Sleep also supports healthy growth and development. Deep sleep triggers the body to release the hormone that promotes normal growth in children and teens. This hormone also boosts muscle mass and helps repair cells and tissues in children, teens, and adults. Sleep also plays a role in puberty and fertility.

Your immune system relies on sleep to stay healthy. This system defends your body against foreign or harmful substances. Ongoing sleep deficiency can change the way in which your immune system responds. For example, if you’re sleep deficient, you may have trouble fighting common infections.

Daytime Performance and Safety

Getting enough quality sleep at the right times helps you function well throughout the day. People who are sleep deficient are less productive at work and school. They take longer to finish tasks, have a slower reaction time, and make more mistakes.

After several nights of losing sleep—even a loss of just 1–2 hours per night—your ability to function suffers as if you haven’t slept at all for a day or two.

Lack of sleep also may lead to microsleep. Microsleep refers to brief moments of sleep that occur when you’re normally awake.

You can’t control microsleep, and you might not be aware of it. For example, have you ever driven somewhere and then not remembered part of the trip? If so, you may have experienced microsleep.

Even if you’re not driving, microsleep can affect how you function. If you’re listening to a lecture, for example, you might miss some of the information or feel like you don’t understand the point. In reality, though, you may have slept through part of the lecture and not been aware of it.

Some people aren’t aware of the risks of sleep deficiency. In fact, they may not even realize that they’re sleep deficient. Even with limited or poor-quality sleep, they may still think that they can function well.

Drowsy drivers may feel capable of driving. Yet, studies show that sleep deficiency harms your driving ability as much as, or more than, being drunk. It’s estimated that driver sleepiness is a factor in about 100,000 car accidents each year, resulting in about 1,500 deaths.

Drivers aren’t the only ones affected by sleep deficiency. It can affect people in all lines of work, including health care workers, pilots, students, lawyers, mechanics, and assembly line workers.

As a result, sleep deficiency is not only harmful on a personal level, but it also can cause large-scale damage. For example, sleep deficiency has played a role in human errors linked to tragic accidents, such as nuclear reactor meltdowns, grounding of large ships, and aviation accidents

Get help

If you are shorting your sleep night after night, it places a tremendous strain on your nervous system, body and overall health. Damage from sleep deficiency can occur in an instant (such as a car crash), or it can harm you over time. For example, ongoing sleep deficiency can raise your risk for some chronic health problems. It also can affect how well you think, react, work, learn, and get along with others.

So, if you’re not sleeping well or aren’t feeling rested when you wake up in the morning, it’s important to talk to your doctor and ask if a sleep study is right for you.

Here comes the sun, and kid sun safety

(HealthDay)—Summer sun brings childhood fun, but experts warn it also brings skin cancer dangers, even for kids.

“Don’t assume children cannot get skin cancer because of their age,” said Dr. Alberto Pappo, director of the solid tumor division at St. Jude Children’s Research Hospital in Memphis, Tenn. “Unlike other cancers, the conventional melanoma that we see mostly in adolescents behaves the same as it does in adults.”

His advice: “Children are not immune from extreme sun damage, and parents should start sun protection early and make it a habit for life.”

So, this and every summer, parents should take steps to shield kids from the sun’s harmful UV rays.

Those steps include:

* Avoid exposure. Infants and children younger than 6 months old should avoid sun exposure entirely, Pappo advised. If these babies are outside or on the beach this summer, they should be covered up with hats and appropriate clothing. It’s also a good idea to avoid being outside when UV rays are at their peak, between 10 a.m. and 2 p.m.

* Use sunscreen. It’s important to apply a broad-spectrum sunscreen to children’s exposed skin. Choose one with at least SPF15 that protects against both UVA and UVB rays. Pappo cautioned that sunscreen needs to be reapplied every couple of hours and after swimming—even if the label says it is “water-resistant.”

However, sunscreen should not be used on infants younger than 6 months old because their exposure to the chemicals in these products would be too high, he noted.

* Keep kids away from tanning beds. Melanoma rates are rising among teenagers, partly due to their use of indoor tanning beds. Use of tanning beds by people younger than 30 boosts their risk for this deadly form of cancer by 75 percent, according to the International Agency for Research on Cancer.

* Get children screened. Early detection of melanoma is key to increasing patients’ odds of survival. Children with suspicious moles or skin lesions should be seen by a doctor as soon as possible, Pappo advised. Removing melanoma in its early stages also increases the chances of avoiding more invasive surgical procedures later on, he added.

Relativity, Radiology and 6 Things You May not Know About Einstein

More than any other profession, radiologists and radiologic technologists put theoretical quantum physics to practical use Improving the health and lives of their patients. Although quantum light theory can explain everything from the tiniest subatomic particles to immense galaxy-devouring black holes, radiologists apply this technology at the human level to diagnose and treat disease and thus alleviate human suffering.

More than 100 years ago in 1895, Wilhelm Conrad Roentgen discovered a form of radiation which had strange new properties. These new rays were so unique and mysterious that he named them “X-rays”, for the unknown. Although often described as a fortuitous discovery, chance favors the prepared mind, and Roentgen’s astute observations back then are still accurate today.

X-rays

6 Things You May not Know About Einstein

  • transmit in complete darkness
  • invisible to the human eye
  • originate from a cathode ray tube
  • expose covered photographic plates
  • diminish in intensity following the inverse square law of light emission
  • soft tissues appear trans­parent, but metal and bone appear opaque.
  • transparency of intervening objects depends on their molecular density and thickness
  • not reflected by mirrors nor deflected by glass prisms
  • travel at a constant speed – the speed of light
  • share some properties with visible light, yet also have uniquely different properties

For the very first time, doctors (without using a scalpel) could see beyond the skin surface of their patients and peer deep inside the human body. It was later found that X-rays were a form of electromagnetic radiation with wavelengths shorter and with energies greater than visible light.

Subsequent research into particle theory by Albert Einstein and others led to the physics principles that not only laid the groundwork for state-of-the-art medical imaging but also changed the understanding of our entire universe, from the mechanics of the atom to the largest objects in the universe. In 1901, Roentgen received the very first Nobel Prize awarded in physics, an indication that his discovery of a form of invisible light was the beginning of a remarkable scientific journey.

Albert Einstein

Albert Einstein’s theories of relativity soon followed and would explain the space time continuum and the equivalence of mass and energy. Throughout his brilliant career, Einstein was fascinated and preoccupied with the strange properties of light. Einstein once said, “For the rest of my life I will reflect on what light is.”

His concept of special relativity came to him when he was riding his bicycle towards a lamp post. He realized that the speed of light was the only constant for all observers and that the classic Newtonian measurements of mass, distance, and time were all subject to change at velocities approaching the speed of light. Einstein’s relativity means that the science fiction adventures of galaxy-hopping space travel in Star Trek and Star Wars are mere fantasy. The vast distances of space and the universal speed limit of light make intergalactic travel too impractical. If a hypothetical space craft approaches the speed of light, time slows, length compresses, the mass of the space craft increases, and impossibly high amounts of energy are required. At a certain point, the space craft stops accelerating, despite greater and greater energy input.

A result of Einstein’s special theory of relativity has been called the most famous equation in all of science. Energy (E) equals mass (m) multiplied by the speed of light squared (c2), that is E=mc2. This simple equation, which states that energy and mass are interchangeable quantities, is often misinterpreted as the formula of the atomic bomb. The principle of the atomic bomb is bom­bardment of a uranium atom with a neutron that splits the uranium atom into two smaller atoms and more neutrons that trigger a fission chain reaction. Although tremendous energy is released, it is the energy of internuclear binding forces, and there is no appreciable change in mass.

A much better demonstration of E=mc2 is the physics of positron emission tomography (PET scan­ning), in which an electron and positron (the antiparticle of an electron) annihilate each other and convert their masses into pure light energy, consisting of photons traveling in opposite directions. This light is detected and calculated as a three-dimensional image of the patient. Einstein was another founder of radiology because his theory of the Photoelectric Effect (published in 1905 and awarded the Nobel Prize in 1921) explained how X-rays interact with matter. This theory also showed that light was absorbed and emitted in discreet packets of energy, leading to the Quantum Theory revolution in physics. 6 Things You May not Know About Einstein

Here are a few more interesting things to know about Einstein’s theory of relativity:

  1. Einstein relied on friends and colleagues to help him develop his theory. 
    Though the theory of general relativity is often presented as a work of solo genius, Einstein actually received considerable help from several lesser-known friends and colleagues in working on the math behind it. College friends Marcel Grossmann and Michele Basso (Einstein supposedly relied on Grossmann’s notes after skipping class) were especially important in the process. Einstein and Grossman, a math professor at Swiss Polytechnic, published an early version of the general relativity theory in 1913, while Besso—whom Einstein had credited in the acknowledgments of his 1905 paper on the special theory of relativity—worked extensively with Einstein to develop the general theory over the next two years. The work of the great mathematicians David Hilbert—more on him later—and Emmy Noether also contributed to the equations behind general relativity. By the time the final version was published in 1916, Einstein also benefited from the work of younger physicists like Gunnar Nordström and Adriaan Fokker, both of whom helped him elaborate his theory and shape it from the earlier version.
  2. The early version of the theory contained a major error. 
    The version published by Einstein and Grossmann in 1913, known as the Entwurf (“outline”) paper, contained a major math error in the form of a miscalculation in the amount a beam of light would bend due to gravity. The mistake might have been exposed in 1914, when German astronomer Erwin Finlay Freundlich traveled to Crimea to test Einstein’s theory during the solar eclipse that August. Freundlich’s plans were foiled, however, by the outbreak of World War I in Europe. By the time he introduced the final version of general relativity in November 1915, Einstein had changed the field equations, which determine how matter curves space-time.
  3. Einstein’s now-legendary paper didn’t make him famous—at first. 
    The unveiling of his masterwork at the Prussian Academy of Sciences—and later in the pages of Annelen Der Physik—certainly afforded Einstein a great deal of attention, but it wasn’t until 1919 that he became an international superstar. That year, British physicist Arthur Eddington performed the first experimental test of the general relativity theory during the total solar eclipse that occurred on May 29. In an experiment conceived by Sir Frank Watson Dyson, Astronomer Royal of Britain, Eddington and other astronomers measured the positions of stars during the eclipse and compared them with their “true” positions. They found that the gravity of the sun did change the path of the starlight according to Einstein’s predictions. When Eddington announced his findings in November 1919, Einstein made the front pages of newspapers around the world.
  4. Another scientist (and former friend) accused Einstein of plagiarism. 
    In 1915, the leading German mathematician David Hilbert invited Einstein to give a series of lectures at the University of Gottingen. The two men talked over general relativity (Einstein was still having serious doubts about how to get his theory and equations to work) and Hilbert began developing his own theory, which he completed at least five days BEFORE Einstein made his presentation in November 1915. What began as an exchange of ideas between friends and fellow scientists turned acrimonious, as each man accused the other of plagiarism. Einstein, of course, got the credit, and later historical research found that he deserved it: Analysis of Hilbert’s proofs showed he lacked a crucial ingredient known as covariance in the version of the theory completed that fall. Hilbert actually didn’t publish his article until March 31, 1916, weeks after Einstein’s theory was already public. By that time, historians say, his theory was covariant.
  5. At the time of Einstein’s death in 1955, scientists still had almost no evidence of general relativity in action. 
    Though the solar eclipse test of 1919 showed that the sun’s gravity appeared to bend light in the way Einstein had predicted, it wasn’t until the 1960s that scientists would begin to discover the extreme objects, like black holes and neutron stars, that influenced the shape of space-time according to the principles of general relativity. Until very recently, they were still searching for evidence of gravitational waves, those ripples in the fabric of space-time caused (according to Einstein) by the acceleration of massive objects. In February 2016, the long wait came to an end, as scientists at the Laser Interferometer Gravitational Wave Observatory (LIGO) announcedthey had detected gravitational waves caused by the collision of two massive black holes.
  6. You can thank Einstein for GPS. 
    Though Einstein’s theory mostly functions among things like PET scanners and in the black holes and cosmic collisions of the heavens, on an ultra-small scale (think string theory), it also plays a role in our everyday lives. GPS technology is one outstanding example of this. General relativity shows that the rate at which time flows depends on how close one is to a massive body. This concept is essential to GPS, which takes into account the fact that time is flowing at a different rate for satellites orbiting the Earth than it is for us on the ground. As a result, time on a GPS satellite clock advances faster than a clock on the ground by about 38 microseconds a day. This might not seem like a significant difference, but if left unchecked it would cause navigational errors within minutes. GPS compensates for the time difference, electronically adjusting rates of the satellite clocks and building mathematical functions within the computer to solve for the user’s exact location—all thanks to Einstein and relativity.

Quantum Theory

Following Einstein’s ideas that light was transmitted in packets of energy, Niels Bohr and Werner Heisenberg developed a model of the atom that diverged from classic Newtonian physics. The Rutherford atomic model consisting of electrons orbiting the central nucleus was inadequate because charged particles changing direction in an orbit would lose energy and fall into the nucleus. Bohr’s model had to explain the Photoelectric Effect, chemical reactions, and the inherent stability of atoms.

A carbon atom can undergo countless chemical reactions yet remains a carbon atom. As Bohr further investigated the atom, the simplistic idea of light just being a wave and electrons just being particles was no longer valid. With the Photoelectric Effect, Einstein showed that light could be a photon particle. Louis de Broglie then showed that particles could be waves. Both photons and electrons have particle-wave duality. The electron therefore could exist as a standing wave around the nucleus, absorb and emit quanta of light energy, and yet remain stable.

The paradoxes that resulted from Bohr’s quantum theory shook the foundations of science. Werner Heisenberg found that the method of investiga­tion alters the result of an experiment. He explained this idea mathematically in his Uncertainty Principle, which remains a major tenet of quantum mechanics. The light used to measure particles imparts energy, altering the momentum or location of the particles, thus changing the results by the mere act of obser­vation. An experiment can be designed to measure either momentum or location precisely, but not both (the experimenter must choose).

“The violent reaction on the recent development of modern physics can only be understood when one realizes that here the foundations of physics have started moving; and that this motion has caused the feeling that the ground would be cut from science.” – Werner Heisenberg

This finding was unsettling for physicists who strove for precise measurements, because precision was not possible at the atomic and subatomic levels. Heisenberg showed that every experiment (and radiologic examination) is subject to limitation. Einstein objected to this inherent fuzziness, stating that “God does not play dice with the Universe.”

The Doppler Effect

Christian Doppler was a professor who studied mathematics, physics, and astronomy. He published a paper on spin­ning binary star systems, noting that starlight shifts to the violet spectrum when a star is moving toward an observer on Earth, and that starlight shifts to the red when a star is moving away. The explanation was that the wavelength of the light wave was compressed or elongated depending on the motion of the source relative to the observer.

When the Doppler Effect is applied to sound, it explains the tone of an approaching or departing train whistle; when applied to radar it pre­dicts violent weather; when applied to ultrasound (another radiology modality) it determines the direction and velocity of blood flow; and when applied to distant starlight it explains our expanding (red shifted) universe. Using Doppler ultrasound, a technologist can screen for: the risk of stroke from carotid artery stenosis, renal arterial causes of hypertension, abdominal aortic aneurysms, periph­eral vascular disease, deep vein thrombosis, portal vein thrombosis and varices, and post-catheterization pseudo-aneurysms.

Countless lives have been saved or improved because of a phenomenon originally observed in starlight. Doppler’s idea extends well beyond the sonography suite and even tells us about the origins of our universe. Edwin Hubble demonstrated that all objects observed in deep space have a Doppler red-shifted veloc­ity that is proportional to the object’s distance from the Earth and all other interstellar bodies. This tells us that our universe is expanding and supports the theory that the universe was created by the Big Bang, which occurred about 13.7 billion years ago.

Old Master Painters

Artists such as Rembrandt and Vermeer (17th century) were adept at depicting light to create the illusion of realistic three-dimensional subjects on two dimensional canvases. These artists studied the interaction of light with their models and understood visual percep­tion of subtle shading and light to make their artwork dramatic and convincing.

Rembrandt van Rijn’s famous por­traits and self-portraits displayed skill with light source positioning and intensity, later duplicated by movie director Cecil B DeMille who coined the term “Rembrandt lighting,” a technique that is still used today by portrait photographers. Johannes Vermeer was skilled at depicting subjects in naturally lit interiors with a subtle photorealistic style that is con­sidered uncanny even today.

Some believe Vermeer used special optics and mirrors because his depiction of light was too subtle for the naked eye to detect.  For example, scientific analysis showed that his backgrounds demonstrated the inverse square law, with exponential diffusion of light, which is difficult to capture when using only an artistic eye.

Experienced radiologic technologists use artistic vision when they create radiographs. By positioning and framing their subjects and by adjusting contrast and exposure, each image can be a work of art, not only pleasing to the eye but also containing a wealth of infor­mation.

Light as the Medium for Medical Imaging

Light, as visual information, is portrayed in art. Light also is the medium for medical imaging, whether in the form of a backlit film, cathode ray tube monitor, liquid crystal display screen, or plasma monitor. The eye is our most complex and highly evolved sense organ, capable of detecting subtle changes in light and color, and transferring this information (via the optic nerves and optic tracts) to the visual cortex of our occipital lobes.

However, what distinguishes artists and seasoned radiology professionals from other people is post-pro­cessing (i.e., the thinking that occurs after perceiving visual data). Much of science and medicine is about logic, language, analysis, and categorization (left brain functions). However, visual processing (the artistic eye) is about conceptualization, spatial orientation, and pattern recognition (right brain functions). These right brain skills are harder to teach and measure but are just as important in radiology.

With the rapid increases in digital image resolution and in the number of multi-planar images involved with each case, developing the right brain is crucial to make sense of this visual information overload. Knowingly or unknowingly, seasoned radiologists develop the right side of their brains through the experience of viewing thousands of medical images. This “artistic eye” can be further enhanced in radiolo­gists and radiologic technologists who appreciate the techniques used by great artists. Or better yet, they can train their right brains by creating original art themselves.

Conclusion

Radiologists and radiologic technologists use light technology and artistic vision in their daily work. They sense subtle shades, recognize patterns, and use symmetry and bal­ance to detect abnormalities. When this artistic skill is applied in combination with an appreciation for the underlying physics that created the images, a thorough knowledge of human anatomy, and an understanding of the pathophysiology of disease, they serve their patients by providing timely diagnosis and excellent medical care.

The Often Misunderstood Diagnosis of Post-Traumatic Stress Disorder

PTSD stands for Post-Traumatic Stress Disorder and is a condition that many veterans and non-veterans alike suffer; PTSD can occur when someone experiences or witnesses a traumatic event. This condition wasn’t always understood properly by the medical or military community, and Department of Defense press releases often point to earlier attempts to identify PTSD symptoms in the wake of service in World War 2, Vietnam, and other conflicts.

PTSD Awareness Day is observed today, Wednesday, June 27, 2018.

The History of PTSD Awareness Day

In 2010, Senator Kent Conrad pushed to get official recognition of PTSD via a “day of awareness” in tribute to a North Dakota National Guard member who took his life following two tours in Iraq.

Staff Sergeant Joe Biel died in 2007 after suffering from PTSD; Biel committed suicide after his return from duty to his home state. SSgt. Biel’s birthday, June 27, was selected as the official PTSD Awareness Day, now observed every year.

How Do People Observe Post-Traumatic Stress Disorder Awareness Day?

Much of what is done to observe PTSD Awareness Day involves encouraging open talk about PTSD, its’ causes, symptoms, and most important of all, getting help for the condition. When today, PTSD is often misunderstood by those lacking firsthand experience with the condition or those who suffer from it. PTSD Awareness Day is designed to help change that.

The Department of Defense publishes circulars, articles, and other materials to help educate and inform military members and their families about the condition. The Department of Veterans Affairs official site has several pages dedicated to PTSD, and when military members retiring or separating from the service fill out VA claim forms for service-connected injuries, illnesses, or disabilities, there is an option to be evaluated for PTSD as a part of the VA claims process.

What Is Post-Traumatic Stress Disorder?

The current American Psychiatric Association’s Diagnostic and Statistical Manual, DSM-IV, says PTSD can develop through a range of exposures to death or injury: direct personal involvement, witnessing it or, if it concerns someone close, just learning about it.  Post-traumatic stress disorder is a form of anxiety that can happen after experiencing or witnessing actual or near death, serious injury, war-related violence, terrorism or sexual violence.  While most people typically connect this disorder to military veterans or refugees, it can happen to anyone.

Almost no other psychiatric diagnosis has generated as much controversy.  The diagnosis is almost four decades old.  PTSD is not a sign of weakness, and people can be affected by PTSD even when they were not directly part of the traumatic event.

The specific nature of the trauma can and does vary greatly. Experts are quick to point out, while combat and combat-related military service can be incredibly challenging, and while witnessing or being a victim of an event that rips the fabric of daily life can be traumatic, not everyone responds the same way. Some may develop symptoms of PTSD, while others may be unaffected.

Post-Traumatic Stress Disorder: How Widespread Is It?

Some sources estimate that as many as 70% of all Americans have experienced a traumatic event sufficient to cause PTSD or PTSD-like symptoms. That does not mean that all 70% of Americans WILL suffer from PTSD. Using these statistics, some 224 million Americans have experienced a traumatic event. Of that number, some 20% will develop PTSD symptoms, roughly 44 million people.

Of that 44 million, an estimated eight percent experience active PTSD symptoms at any one time. An estimated 50% of all mental health patients are also diagnosed with Post-Traumatic Stress Disorder.

PTSD: Often Misunderstood and Misidentified

“Shell shock” and “combat shock” were earlier attempts to define and understand the symptoms of PTSD. Post-traumatic stress disorder was often stigmatized in popular culture after the Vietnam conflict, and many films and television shows featured antagonists or unsympathetic characters suffering from “Vietnam flashbacks” or other issues.

The misunderstanding of PTSD slowly began to change in 1980 when it was recognized as a specific condition with identifiable symptoms. It was then the disorder was listed in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM).

This manual is a diagnostic tool for mental health professionals and paraprofessional workers in the healthcare field and is considered a definitive reference. The addition of PTSD to the DSM was a highly significant development.

Today, the symptoms of Post Traumatic Stress Disorder are better understood, treatable, and recognized by the Department of Veterans Affairs as a service-connected condition. PTSD is not exclusive to veterans or currently serving members of the United States military, but a portion of those who serve are definitely at risk for PTSD.

What Are the Symptoms of Post-Traumatic Stress Syndrome?

Some PTSD symptoms may seem vague and non-specific, others are more readily identified specifically as evidence of PTSD. In this context “non-specific” means that the symptoms may be related to other mental health issues and not specifically limited to Post-Traumatic Stress Disorder.

In the same way, more “specific” symptoms may be manifest outside PTSD, but when looking for specific signifiers, these issues are common “red flags” that indicate PTSD may be the cause of the suffering rather than a different condition. This is often circumstantial, and there is no one-size-fits-all diagnosis for the condition.

Suicidal thoughts or self-destructive acts are often a result of PTSD or related symptoms. Anyone experiencing thoughts or urges to self-harm should seek immediate care to prevent the condition from getting worse in the short-term. (See below)

That said, more non-specific symptoms include varying degrees of irritability, depression, and suicidal feelings. More specific problems-especially where veterans and currently serving military members are concerned-include something known as “hypervigilance” or “hyperarousal”.

Other symptoms include repeatedly experiencing the traumatic event(s) in the form of flashbacks, nightmares, persistent memories of the event(s), and intrusive thoughts about the traumatic event(s).

These symptoms vary in intensity depending on the individual and are not ‘standardized”. They may come and go, or they may be persistent over a span of time. Sometimes PTSD sufferers can be high-functioning, other times they may be more debilitated by the condition.

Get Treatment For PTSD

Those who experience symptoms of PTSD or PTSD-like issues should seek help immediately. Department of Veterans Affairs medical facilities, private care providers, counselors, and therapists can all be helpful in establishing an initial care regimen or refer those suffering from PTSD to a qualified care provider.

The Department of Veterans Affairs has more information on help for PTSD on its’ official site including help finding a therapist.

Those experiencing suicidal feelings or self-destructive urges should get help immediately. The Suicide Crisis Hotline (1-800-273-8255) has a specific resource for veterans and the Department of Veterans Affairs offers a Veterans’ Crisis Hotline confidential chat resource.

“Doing It My Way, Testing for HIV” | HIV Testing Day 2018

National HIV Testing Day (NHTD) is an annual observance encouraging people of all ages to get tested for HIV and to know their status.  Too many people are unaware they have HIV. At the end of 2014, an estimated 1.1 million persons aged 13 and older were living with HIV infection in the United States, including an estimated 166,000 (15%, or 1 in 7) persons whose infections had not been diagnosed.

Getting tested is the first step to finding out if you have HIV. If you have HIV, getting medical care, taking medicines regularly and changes in behavior help you live a longer, healthier life and will lower the chances of passing HIV on to others.

Testing is the only way for the Americans living with undiagnosed HIV to know their HIV status and get into care. CDC estimates that more than 90% of all new infections could be prevented by proper testing and linking HIV positive persons to care. HIV testing saves lives! It is one of the most powerful tools in the fight against HIV

How do I know if I am at risk to get HIV? 

Knowing your risk can help you make important decisions to prevent exposure to HIV.  Overall, an American has a 1 in 99 chance of being diagnosed with HIV at some point in his or her lifetime. However, the lifetime risk is much greater among some populations. If current diagnosis rates continue the lifetime risk of getting HIV is:

  • 1 in 6 for gay and bisexual men overall
  • 1 in 2 for African American gay and bisexual men
  • 1 in 4 for Hispanic gay and bisexual men
  • 1 in 11 for white gay and bisexual men
  • 1 in 20 for African American men overall
  • 1 in 48 for African American women overall
  • 1 in 23 for women who inject drugs
  • 1 in 36 for men who inject drugs

Your health behaviors also affect your risk. You can get or transmit HIV only through specific activities. HIV is commonly transmitted through anal or vaginal sex without a condom or sharing injection and other drug injection equipment with a person infected with HIV. Substance use can increase the risk of exposure to HIV because alcohol and other drugs can affect your decision to use condoms during sex. To learn more about your HIV risk and ways to reduce these risks, visit: https://wwwn.cdc.gov/hivrisk/

How do HIV, Viral Hepatitis, and STDs relate to each other? 

Persons who have an STD are at least two to five times more likely than uninfected persons to acquire HIV infection if they are exposed to the virus through sexual contact. In addition, if a person who is HIV positive also has an STD, that person is more likely to transmit HIV through sexual contact than other HIV-infected persons.

Hepatitis B virus (HBV) and HIV are bloodborne viruses transmitted primarily through sexual contact and injection drug use. Because of these shared modes of transmission, a high proportion of adults at risk for HIV infection are also at risk for HBV infection. HIV-positive persons who become infected with HBV are at increased risk for developing chronic HBV infection and should be tested. In addition, persons who are co-infected with HIV and HBV can have serious medical complications, including an increased risk for liver-related morbidity and mortality.

Hepatitis C Virus (HCV) is one of the most common causes of chronic liver disease in the United States. For persons who are HIV infected, co-infection with HCV can result in a more rapid occurrence of liver damage and may also impact the course and management of HIV infection.

How do I protect myself and others from HIV, Viral Hepatitis, and STDs? 

HIV Prevention

Your life matters and staying healthy is important. It’s important for you, the people who care about you, and your community that you know your HIV status.  Knowing give you powerful information to help take steps to keep you and others healthy. You should get tested for HIV, and encourage others to get tested too.

For people who are sexually active, there are more tools available today to prevent HIV than ever before. The list below provides a number of ways you can lower your chances of getting HIV. The more of these actions you take, the safer you can be.

  • Get tested and treated for other STDs and encourage your partners to do the same.All adults and adolescents from ages 13-64 should be tested at least once for HIV, and high-risk groups get tested more often.  STDs can have long-term health consequences.  They can also increase your chance of getting HIV or transmitting it to others. It is important to have an honest and open talk with your healthcare provider and ask whether you should be tested for STDs.  Your healthcare provider can offer you the best care if you discuss your sexual history openly.
  • Choose less risky sexual behaviors. Oral sex is much less risky than anal or vaginal sex for HIV transmission. Anal sex is the highest-risk sexual activity for HIV transmission. Sexual activities that do not involve the potential exchange of bodily fluids carry no risk for getting HIV (e.g., touching).
  • Use condoms consistently and correctly.
  • Reduce the number of people you have sex with.  The number of sex partners you have affects your HIV risk. The more partners you have, the more likely you are to have a partner with HIV whose viral load is not suppressed or to have a sex partner with a sexually transmitted disease. Both of these factors can increase the risk of HIV transmission.
  • Talk to your doctor about pre-exposure prophylaxis (PrEP). CDC recommends that PrEP be considered for people who are HIIV-negative and at substantial risk for being exposed to HIV.For sexual transmission, this includes HIIV-negative persons who are in an ongoing relationship with an HIV-positive partner. It also includes anyone who 1) is not in a mutually monogamous relationship with a partner who recently tested HIV-negative, and 2) is a gay or bisexual man who has had sex without a condom or been diagnosed with an STD in the past 6 months; or heterosexual man or woman who does not regularly use condoms during sex with partners of unknown HIV status who are at substantial risk of HIV infection (e.g., people who inject drugs or have bisexual male partners). For people who inject drugs, this includes those who have injected drugs in the past 6 months and who have shared injection equipment or been in drug treatment for injection drug use in the past 6 months.
  • Talk to your doctor right away (within 3 days) about post-exposure prophylaxis (PEP) if you have a possible exposure to HIV. An example of a possible exposure is if you have anal or vaginal sex without a condom with someone who is or may be HIV-positive, and you are HIV-negative and not taking PrEP. Your chance of exposure to HIV is lower if your HIV-positive partner is taking antiretroviral therapy (ART) consistently and correctly, especially if his/her viral load is undetectable. Starting medicine immediately (known as post-exposure prophylaxis, or PEP) and taking it daily for 4 weeks reduces your chance of getting HIV.
  • If your partner is HIV-positive, encourage your partner to get and stay on treatment.  ART reduces the amount of HIV virus (viral load) in blood and body fluids. ART can keep people with HIV healthy for many years, and greatly reduce the chance of transmitting HIV to sex partners if taken consistently and correctly.

Hepatitis Prevention

The best way to prevent both Hepatitis A and B is by getting vaccinated.   There is no vaccine available to prevent Hepatitis C.  The best way to prevent Hepatitis C is by avoiding behaviors that can spread the disease, such as sharing needles or other equipment to inject drugs.

STD Prevention

The only way to avoid STDs is to not have vaginal, anal, or oral sex. If you are sexually active, you can do several things to lower your chances of getting an STD, including:

  • Get tested for STDs and encourage your partner(s) to do the same. It is important to have an honest and open talk with your healthcare provider and ask whether you should be tested for STDs.  Your healthcare provider can offer you the best care if you discuss your sexual history openly.
  • Get vaccinated. Vaccines are safe, effective, and recommended ways to prevent hepatitis A, hepatitis B, and HPV.
  • Be in a sexually active relationship with only one person, who has agreed to be sexually active only with you.
  • Reduce your number of sex partners.  By doing so, you decrease your risk for STDs. It is still important that you and your partner get tested, and that you share your test results with one another.
  • Use a condom every time you have vaginal, anal, or oral sex. Correct and consistent use of the male latex condomis highly effective in reducing STD transmission.

What puts me at risk for HIV, Viral Hepatitis, and STDs? 

Risks for HIV

The most common ways HIV is transmitted in the United States is through anal or vaginal sex or sharing drug injection equipment with a person infected with HIV. Although the risk factors for HIV are the same for everyone, some racial/ethnic, gender, and age groups are far more affected than others.

What puts me at risk for Hepatitis A?

Hepatitis A is usually spread when a person ingests fecal matter — even in microscopic amounts — from contact with objects, food, or drinks contaminated by the feces or stool of an infected person. Due to routine vaccination of children, Hepatitis A has decreased dramatically in the United States. Although anyone can get Hepatitis A, certain groups of people are at higher risk, including men who have sex with men, people who use illegal drugs, people who travel to certain international countries, and people who have sexual contact with someone who has Hepatitis A.

What puts me at risk for Hepatitis B?

Hepatitis B is usually spread when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact with an infected person or sharing needles, syringes, or other drug-injection equipment. Hepatitis B can also be passed from an infected mother to her baby at birth.

Among adults in the United States, Hepatitis B is most commonly spread through sexual contact and accounts for nearly two-thirds of acute Hepatitis B cases. Hepatitis B is 50–100 times more infectious than HIV.

What puts me at risk for Hepatitis C?

Hepatitis C is usually spread when blood from a person infected with the Hepatitis C virus enters the body of someone who is not infected. Today, most people become infected with the Hepatitis C virus by sharing needles or other equipment to inject drugs. Hepatitis C was also commonly spread through blood transfusions and organ transplants prior to the early 1990’s. At that time, widespread screening of the blood supply began in the United States, which has helped ensure a safe blood supply.

STDs

Risks for  Genital Herpes

Genital herpes is a common STD, and most people with genital herpes infection do not know they have it.   You can get genital herpes from an infected partner, even if your partner has no herpes symptoms.  There is no cure for herpes, but medication is available to reduce symptoms and make it less likely that you will spread herpes to a sex partner.

Risks for Genital Human Papillomavirus (HPV)

HPV is so common that most sexually active people get it at some point in their lives. Anyone who is sexually active can get HPV, even if you have had sex with only one person. In most cases, HPV goes away on its own and does not cause any health problems. But when HPV does not go away, it can cause health problems like genital warts and cancer. HPV is passed on through genital contact (such as vaginal and anal sex). You can pass HPV to others without knowing it.

Risks for Chlamydia

Most people who have chlamydia don’t know it since the disease often has no symptoms.  Chlamydia is the most commonly reported STD in the United States.  Sexually active females 25 years old and younger need testing every year. Although it is easy to cure, chlamydia can make it difficult for a woman to get pregnant if left untreated.

Risks for Gonorrhea

Anyone who is sexually active can get gonorrhea, an STD that can cause infections in the genitals, rectum, and throat. It is a very common infection, especially among young people ages 15-24 years. But it can be easily cured.  You can get gonorrhea by having anal, vaginal, or oral sex with someone who has gonorrhea. A pregnant woman with gonorrhea can give the infection to her baby during childbirth.

Risks for Syphilis

Any sexually active person can get syphilis. It is more common among men who have sex with men. Syphilis is passed through direct contact with a syphilis sore. Sores occur mainly on the external genitals, anus, or in the rectum. Sores also can occur on the lips and in the mouth. A pregnant women with syphilis can give the infection to her unborn baby.

Risks for Bacterial Vaginosis

BV is common among women of childbearing age. Any woman can get BV, but women are at a higher risk for BV if they have a new sex partner, multiple sex partners, use an intrauterine device (IUD), and/or douche.

Managing Your Appointments

HIV is a treatable condition. If you are diagnosed early, get on antiretroviral therapy (ART), and adhere to your medication, you can stay healthy, live a normal life span, and reduce the chances of transmitting HIV to others. Part of staying healthy is seeing your HIV care provider regularly so that he or she can track your progress and make sure your HIV treatment is working for you.

Your HIV care provider might be a doctor, nurse practitioner, or physician assistant. Some people living with HIV go to an HIV clinic; others see an HIV specialist at a community health center, Veterans Affairs clinic, or other health clinic; and some people see their provider in a private practice. Current guidelines recommend that most people living with HIV see their provider for lab tests every 3 to 4 months. Some people may see their provider more frequently, especially during the first two years of treatment or if their HIV viral load is not suppressed (i.e. very low or undetectable). Current guidelines say that people who take their medication every day and have had a suppressed viral load at every test for more than 2 years only need to have their lab tests done two times a year.

In addition to seeing your HIV care provider, you may need to see other health care practitioners, including dentists, nurses, case managers, social workers, psychiatrists/psychologists, pharmacists and medical specialists. This may mean juggling multiple appointments, but it is all part of staying healthy. You can help make this easier by preparing a plan for yourself.

Before Your Visit

For many people living with HIV, appointments with their HIV care provider become a routine part of their life. These tips may help you better prepare for your visits to your HIV care provider and get more out of them:

  • Start with a list or a notebook. Write down any questions you have before you go. (The Department of Veterans Affairs offers a useful list of sample questions you can bring with you.)
  • Make a list of your health and life goals so that you can talk about them with your HIV provider and how she/he can help you reach them.
  • Make a list of any symptoms or problems you are experiencing that you want to talk to your provider about.
  • Bring a list of all the HIV and non-HIV medications that you are taking (or the medications themselves), including over-the-counter medications, vitamins, or supplements. Include a list of any HIV medications you may have taken in the past and any problems you had when taking them.
  • Bring along a copy of your medical records if you are seeing a new provider who does not already have them. You have the right to access your medical records and having copies of your records can help you keep track of your lab results, prescriptions, and other health information. It can also help your new provider have a better understanding of your health history. The best way to do this is by using a global, portable personal health record like the one you will maintain here at HealthLynked.
  • Be prepared to talk about any changes in your living situation, relationships, insurance, or employment that may affect your ability to keep up with your HIV appointments and treatment or to take care of yourself. Your provider may be able to connect you with resources or services that may assist you.
  • Be on time. Most healthcare providers have full appointment schedules—if you are late, you throw the schedule off for everyone who comes after you. If you are late, there is a chance your provider will not be able to see you the same day.

During Your Visit

  • If your provider wants to run some lab tests during your visit, make sure you understand what the lab tests are for and what your provider will do with the results. If you don’t understand, ask your provider to explain it in everyday terms. Typically, you will be asked to give a sample (blood, urine) during your visit and your provider’s office will call you with your results in a few days. Keep track of your results and call your provider back if you have any questions.
  • Be honest. Your provider isn’t there to judge you, but to make decisions with you based on your particular circumstances. Talk about any HIV medication doses you have missed. Tell your provider about your sexual or alcohol/drug use history. These behaviors can put you at risk of developing drug resistance and getting other sexually transmitted infections (STIs) as well as hepatitis. Your provider will work with you to develop strategies to keep you as healthy as possible.
  • Describe any side effects you may be having from your HIV medications. Your provider will want to know how the HIV medications are affecting your body in order to work with you to solve any problems and find the right combination of medications for you.
  • Ask your provider about your next visit and what you should bring to that appointment.
  • Ask for a list of your upcoming appointments when you check out. Work with your case manager, if you have one, to develop a system to help you remember your appointments, such as a calendar, app, or text/e-mail reminders.

Asking Questions and Solving Problems

It’s important for you to be an active participant in your own health care and it’s your right to ask questions. You may need to direct your questions to different people, depending on what you need/want to know:

HIV care providers (doctors, nurse practitioners, physician assistants) can answer specific questions about a wide range of issues that affect your health. They can also help you find resources and solutions to problems you may have that affect your health, including:

  • Your prognosis (how your HIV disease is affecting your body)
  • How to manage any symptoms you may be experiencing
  • Medication issues, including medication changes, new medications, and how the HIV medications may interact with other medications you take.
  • Sexual health issues, including questions about any sexual symptoms you may be having, and how you can prevent or treat STIs, and how you can prevent transmitting HIV to your partner(s).
  • Family planning considerations, including your goals; birth control options for you and/or your partner, if relevant; your options for having children should you wish to do so; and, if you are an HIV-positive woman who is pregnant or considering getting pregnant, how you can reduce the risk of transmitting HIV to your baby
  • Substance use issues, including how alcohol/drug use can affect your HIV treatment and overall health, and whether you should be referred for substance abuse treatment
  • Mental health issues, including questions about any mental health symptoms you may be having, and whether you should be referred for mental health treatment
  • Referrals for other medical issues you may be experiencing
  • The meaning of lab test results
  • The need for surgical procedures, if relevant
  • Medication adherence strategies (tips for keeping up with your medication and ensuring you take it as scheduled and exactly as prescribed)
  • Any clinical trials or research studies that may be relevant for you
  • Information about resources and services that can help you with issues or challenges you may be having that affect your health.

Nurses and case managers often have more time to answer questions about what you discuss with your provider and to help identify solutions to problems that are affecting your health, particularly around:

  • Understanding your HIV treatment plan, including how many pills of each medicine you should take; when to take each medicine; how to take each medicine (for example, with or without food); and how to store each medicine
  • Understanding possible side effects from your HIV medication and what you should do if you experience them
  • Challenges you may have in taking your medications and/or keeping your medical appointments, and strategies for overcoming these challenges
  • Resources to help you better understand lab reports, tests, and procedures
  • Mental health and/or substance abuse treatment, housing assistance, food assistance, and other resources that exist in your community
  • Insurance and pharmacy benefits, and other aspects of paying for care
  • Understanding other medical conditions you may have
  • How to quit smoking and resources that are available to assist you
  • Information about resources and services that can help you with issues or challenges you may be having that affect your health.

If you are HIV positive, attending your medical appointments is one of the most important things you can do to ensure your HIV is optimally managed.

Forgiveness Fills Life with Research Proven Health Benefits

Maybe you are considering forgiveness for yourself or others, but you’re not sure it’s worth the emotional effort. You might prefer to ignore the painful memories, stuff it down and keep going about your daily affairs. You will just deal with it later, right?

To forgive, whether yourself or others, and to be forgiven, brings relief beyond just the emotional or even spiritual, if you at a person of faith.  Today is Forgiveness Day – one of many observed throughout the year.  The original was established as International Forgiveness Day in response to a call to set aside old differences made by Desmond Tutu.  There is also Global Forgiveness Day next Saturday, and National Forgiveness Day in October.  All have one purpose – to encourage us to set things right; and there are great health benefits to doing so!

Whether it’s a bout with your boss, a feud with a family member or friend, or a spat with your spouse, unresolved conflict can go deeper than you may realize—it may be affecting your physical health. Not forgiving has its costs. When we harbor grudges and grievances, we retain everything that goes with them: anxiety, irritability, anger, and depression.  We may suffer insomnia, experience weight gain or loss, endure depletion of trust in ourselves and others, get caught up in numbing addictions and get stuck in a nerve fraying fight-or-flight mode.

The list is long and disabling.  The good news: Studies have found the act of forgiveness can pay huge dividends for your health, And research points to an increase in the forgiveness-health connection as you age.

What are the health benefits of forgiveness?

In a study at Virginia Commonwealth University, researchers sought to prove what many might already feel is common sense. They wrote, “Chronic unforgiveness causes stress. Every time people think of their transgressor, their body responds. Decreasing your unforgiveness cuts down your health risk. Now, if you can forgive, that can actually strengthen your immune system.” [1]

Dr. Bernie Siegel, author, surgeon and retired medical professor at Yale University, said, “I have collected 57 extremely well-documented so-called cancer miracles. At a certain particular moment in time, they decided that the anger and the depression were probably not the best way to go, since they had such little time left.

And so, they went from that to being loving, caring, no longer angry, no longer depressed, and able to talk to the people they loved. These 57 people had the same pattern. They gave up—totally—their anger, and they gave up—totally—their depression, by specifically a decision to do so. And at that point, the tumors started to shrink.” [2]

Medical researchers have become increasingly interested in studying the effects of forgiveness as a healing process. Evidence is mounting:  holding onto painful memories and bitterness results in long-term health problems. Forgiveness, on the other hand, offers numerous benefits, including:

  1. Lower blood pressure

When we no longer feel anxiety or anger because of past grievances, our heart rate evens out and our blood pressure drops. This normalizes many processes in the body and brings us our heart and circulatory system into stability.

  1. Stress reduction

Forgiveness eases stress because we no longer recycle thoughts (both consciously and subconsciously) that cause psychic stress to arise. By offering our burdens for healing, we learn how to leave irritation and stress behind.

  1.  Less hostility

By its very nature, forgiveness asks us to let go of hostility toward ourselves and others.  Spontaneous hostile behavior, like road rage and picking a fight for no reason, diminishes as our commitment to forgiveness goes up.

  1. Better anger-management skills

With fewer and fewer burdens from the past weighing us down, we have more self-control when we do get angry. We’ll be better able to take some breaths, count to ten, take a time-out or get some exercise—rather than strike out or lash out in anger.

  1. Lower heart rate

Forgiveness relaxes our hearts –  pain will ease out of our system. Our hearts calm down, and our heart rate decreases as a result.

  1. Lower risk of alcohol or substance abuse

This is a big one – possibly the biggest and best reason to jump into a forgiveness practice without delay. Substance abuse is a mask for underlying pain. Forgiveness helps release that pain and find the gifts in our situation instead.

  1. Fewer depression symptoms

Similar to lowering substance abuse, this is a crucial issue with retained anguish. Depression is debilitating and can lead to suicide. On the other hand, forgiveness gives us healing and can leave room to replace depression with a sense of purpose and compassion.

  1. Fewer anxiety symptoms

Almost everyone needs to forgive him or herself as well as others. Anxiety often arises when we fear we’ve done something wrong. Our guilty conscience causes tension at a deep level. Forgiveness helps us to love ourselves deeply, relieving inner pain.

  1. Reduction in chronic pain

Physical pain often has psychological underpinnings. When we allow a profound shift to happen with forgiveness, we heal ourselves on both psychological and physical levels. Thus, chronic pain can be reversed, and we can be restored to best health.

  1. More friendships

When we’re no longer holding grudges, we can get a lot closer to friends and family. Old relationships have a chance to change and grow, and new relationships can enter—all because we made room for them with forgiveness.

  1. Healthier relationships

When we make forgiveness a regular part of our emotional practice, we start to notice all of our relationships begin to blossom. There’s far less drama to deal with, and that’s a huge bonus.

  1. Improved psychological well-being

A good life, full of quality relationships, service to others and fun, is something that most of us hope for without ever knowing how to create it.  By releasing our grievances, we become more harmonious on all levels. Nightmares recede, and exciting new life visions become commonplace. We feel calmer, happier and ready to give compassion and love to the world.

  1. Enhanced immune function

Forgiveness lowers cortisol – a steroid hormone produced in response to stress that causes weight gain – and boosts immune function. You’ll feel more relaxed and centered, and you won’t get sick as easily once you’ve let go for good through forgiveness.

Looking at the list, it’s easy to see that if you had lower stress, hostility, blood pressure and chronic pain, you’d be far healthier for it. Also, if you had better relationships, improved psychological well-being and greater emotional connection, you could be living a life of joy and purpose.

Can You Learn to Be More Forgiving?

Now, look at this list below to see if you would enjoy improvements in any of these areas of your life:

  • Your Physical Health
  • Relationships with Loved Ones (Lovers, Spouse, Exes, and Friends)
  • Family Issues with Parents, Siblings and Children
  • Trauma from Childhood
  • Impacts of Racism, Sexism and Other “Isms”
  • Money Worries
  • Sexual Issues
  • Blocked Creativity

Forgiveness is not just about saying the words. It is an active process in which you make a conscious decision to let go of negative feelings whether deserved or not. As you release anger, resentment and hostility, you make room for empathy, compassion and sometimes even affection for the person who wronged you.

Studies have found some people are just naturally more forgiving. Consequently, they tend to be more satisfied with their lives and to have less depression, anxiety, stress, anger and hostility. People who hang on to grudges, however, are more likely to experience severe depression and even post-traumatic stress disorder, as well as other health issues described earlier. But that doesn’t mean they can’t train themselves to act in healthier ways. 62 percent of American adults say they need more forgiveness in their personal lives, according to a survey by the nonprofit Fetzer Institute.

Making Forgiveness Part of Your Life

Forgiveness is a choice.  You are choosing to offer compassion and empathy to the person who wronged you.  The following steps can help you develop a more forgiving attitude—and benefit from better emotional and physical health.

Reflect and remember.

That includes the events themselves, and also how you reacted, how you felt, and how the anger and hurt have affected you since.

Empathize with the other person.

For instance, if your spouse grew up in an alcoholic family, then anger when you have too much to drink might be understandable.

Forgive deeply.

Simply forgiving someone because you think you have no other alternative or because you think your faith requires it may be enough to bring some healing, but one study found people whose forgiveness came in part from understanding no one is perfect were able to resume a normal relationship with the other person.  This was true even if that person never apologized. Those who only forgave in an effort to salvage the relationship typically wound up with a worse relationship.

Let go of expectations.

An apology may not change your relationship with the other person or elicit an apology from them. If you don’t expect either, you won’t be disappointed.

Decide to forgive.

Once you make that choice, seal it with an action. If you don’t feel you can talk to the person who wronged you, write about your forgiveness in a journal or even talk about it with someone else in your life whom you trust and can be supportive.

Forgive yourself.

The act of forgiving includes forgiving yourself. Failings of the past are not a reflection of your worth.

If you are suffering any of the debilitating effects of unforgiveness, it is a great day to relieve yourself and others of the tremendous burden of holding on to hurt.  And if you need a professional to speak with about any of the physical effects you are feeling, find them in HealthLynked.

Five [PLUS] Senses Working Overtime. Are You Tuned In…?

Today is Celebration of the Senses Day – a time to consider your amazing sensory abilities and how they interrelate. We all learn as children humans have five basic senses: touch, sight, hearing, smell and taste. Science has done a fantastic job describing the organs associated with each, how they send information to the brain to help us understand and perceive the world around us, and has gone even further to uncover how they uniquely cross-talk for heightened awareness.

Touch

Touch is thought to be the first sense humans develop, according to the Stanford Encyclopedia of Philosophy. Touch consists of several distinct sensations communicated to the brain through specialized neurons in the skin. Pressure, temperature, light touch, vibration, pain and other sensations are all part of the touch sense and are all attributed to different receptors in the skin.

Touch isn’t just a sense used to interact with the world; it also seems to be very important to a human’s well-being. For example, touch has been found to convey compassion from one human to another.

Touch can also influence how humans make decisions. Texture can be associated with abstract concepts, and touching something with a texture can influence the decisions a person makes, according to six studies by psychologists at Harvard University and Yale University, published in the June 24, 2010, issue of the journal Science.

“Those tactile sensations are not just changing general orientation or putting people in a good mood,” said Joshua Ackerman, an assistant professor at the Massachusetts Institute of Technology. “They have a specific tie to certain abstract meanings.”

Sight

Sight, or perceiving things through the eyes, is a complex process. First, light reflects off an object to the eye. The transparent outer layer of the eye – the cornea – bends the light that passes through the hole of the pupil. The iris (the colored part of the eye) works like the shutter of a camera, retracting to shut out light or opening wider to let in more light.

The cornea focuses most of the light. Then, it passes through the lens, which continues to focus the light.  The lens of the eye then bends the light and focuses it on the retina, which is full of nerve cells. These cells are shaped like rods and cones and are named for their shapes. Cones translate light into colors, central vision and details. The rods translate light into peripheral vision and motion. Rods also give humans vision when there is limited light available, like at night. The information translated from the light is sent as electrical impulses to the brain through the optic nerve.

People without sight may compensate with enhanced hearing, taste, touch and smell, according to numerous studies. Their memory and language skills may be better than those with sight, as well.

“Even in the case of being profoundly blind, the brain rewires itself in a manner to use the information at its disposal so that it can interact with the environment in a more effective manner.”  That’s according to Dr. Lotfi Merabet, senior author of a 2017 study and the director of the Laboratory for Visual Neuroplasticity at Schepens Eye Research Institute of Massachusetts Eye and Ear.

Hearing

This sense works via the complex labyrinth that is the human ear. Sound is funneled through the external ear and piped into the external auditory canal. Then, sound waves reach the tympanic membrane, or eardrum. This is a thin sheet of connective tissue that vibrates when sound waves strike it.

The vibrations travel to the middle ear. There, auditory ossicles — three tiny bones called the malleus (hammer), incus (anvil) and stapes (stirrup) — vibrate. The stapes bone, in turn, pushes a structure called the oval window in and out, sending vibrations to the organ of Corti.  This spiral organ is the receptor organ for hearing. Tiny hair cells in the organ of Corti translate the vibrations into electrical impulses. The impulses then travel to the brain via sensory nerves.

People retain their sense of balance because the Eustachian tube, or pharyngotympanic tube, in the middle ear equalizes the air pressure there with the air pressure in the atmosphere. The vestibular complex, in the inner ear, is also important for balance, because it contains receptors that regulate a sense of equilibrium. The inner ear is connected to the vestibulocochlear nerve, which carries sound and equilibrium information to the brain.

Smell

Humans may be able to smell over 1 trillion scents, according to researchers. They do this with the olfactory cleft, which is found on the roof of the nasal cavity, next to the “smelling” part of the brain – the olfactory bulb and fossa. Nerve endings in the olfactory cleft transmit scents to the brain, according to the American Rhinologic Society.

Dogs are known as great smellers, but research suggests humans are just as good as man’s best friend. Research published in the May 11, 2017, issue of the journal Science suggests humans can discriminate among 1 trillion different odors; it was once believed humans could discern only about 10,000 different smells.

“The fact is the sense of smell is just as good in humans as in other mammals, like rodents and dogs,” John McGann, a neuroscientist at Rutgers University-New Brunswick in New Jersey and the author of the new review, said in a statement. The Rutgers study backs up a previous study at the Rockefeller University in New York, whose findings were published in the March 2014 issue of the journal Science.

Humans have 400 smelling receptors. While this isn’t as many as animals that are super smellers have, the much more complicated human brain makes the difference.  In fact, poor smelling ability in people may be a symptom of a medical condition or aging. For example, the distorted or decreased ability to smell is a symptom of schizophrenia and depression. Old age can also lessen the ability to smell properly. More than 75 percent of people over the age of 80 years may have major olfactory impairment, according to a 2006 paper published by the National Institutes of Health (NIH).

Taste

The gustatory sense is usually broken down into the perception of four different tastes: salty, sweet, sour and bitter. There is also a fifth taste, defined as umami or savory. There may be many other flavors not yet discovered. Also, spicy is not a taste. It is actually a pain signal, according to the National Library of Medicine (NLM).

The sense of taste aided in human evolution, according to the NLM, because taste helped people test the food they ate. A bitter or sour taste indicated that a plant might be poisonous or rotten. Something salty or sweet, however, often meant the food was rich in nutrients.

Taste is sensed in the taste buds. Adults have 2,000 to 4,000 taste buds. Most of them are on the tongue, but they also line the back of the throat, the epiglottis, the nasal cavity and the esophagus. Sensory cells on the buds form capsules shaped like flower buds or oranges. The tips of these capsules have pores that work like funnels with tiny taste hairs. Proteins on the hairs bind chemicals to the cells for tasting.

It is a myth that the tongue has specific zones for each flavor. The five tastes can be sensed on all parts of the tongue, although the sides are more sensitive than the middle. About half of the sensory cells in taste buds react to several of the five basic tastes. The cells differ in their level of sensitivity. Each has a specific palette of tastes with a fixed ranking, so some cells may be more sensitive to sweet, followed by bitter, sour and salty, while others have their own rankings. The full experience of a flavor is produced only after all of the information from various parts of the tongue is combined.

The other half of the sensory cells are specialized to react to only one taste. It’s their job to transmit information about the intensity — how salty or sweet something tastes.

Other factors help build the perception of taste in the brain. For example, the smell of the food greatly affects how the brain perceives the taste. Smells are sent to the mouth in a process called olfactory referral. This is why someone with a stuffy nose may have trouble tasting food properly. Texture, translated by the sense of touch, also contributes to taste, and recent studies even show color and shape can affect the way we perceive a properly attribute taste to a food.

The sense of space

In addition to the traditional big five, other senses help us translate a myriad of inputs into how we perceive and relate to the physical world.  One deals with how your brain understands where your body is in space. This sense is called proprioception.

Proprioception includes the sense of movement and position of our limbs and muscles. For example, proprioception enables a person to touch their finger to the tip of their nose, even with their eyes closed. It enables a person to climb steps without looking at each one. People with poor proprioception may be clumsy and uncoordinated.

Researchers at the NIH found that people who have particularly poor proprioception through mechanosensation — the ability to sense force, such as feeling when someone presses down on your skin — may have a mutated gene that is passed down from generation to generation. That comes from a September 2016 study in the New England Journal of Medicine. “The patient’s version of [the gene] PIEZO2 may not work, so their neurons cannot detect touch or limb movements,” said Alexander Chesler, a principal investigator at the National Center for Complementary and Integrative Health and the lead author of the study.

Additional senses & variations

There are more-subtle senses that most people never really perceive. For example, there are neuron sensors that sense movement to control balance and the tilt of the head. Specific kinesthetic receptors exist for detecting stretching in muscles and tendons, helping people to keep track of their limbs. Other receptors detect levels of oxygen in certain arteries of the bloodstream.

While our five  basic sense seem to operate independently, as distinct modes of perceiving the world, in reality, they collaborate closely to enable the mind to better understand our surroundings. We can become keenly aware of this collaboration under special conditions.

In some cases, a sense may covertly influence another we think is dominant. When visual information clashes with that from sound, sensory crosstalk can cause what we see to alter what we hear. When one sense drops out, another can pick up the slack.  For instance, people who are blind can train their hearing to play double duty. Those who are both blind and deaf can train touch to step in—even to help them interpret speech.

Our senses must also regularly meet and greet in the brain to provide accurate impressions of the world. Our ability to perceive the emotions of others relies on combinations of cues from sounds, sights and even smells.  Perceptual systems, particularly smell, connect with memory and emotion centers to enable sensory cues to trigger feelings and recollections, and are incorporated within them.

The crosstalking of the senses provides some of the most magnificent material for interesting science, illusions, inventions and just plain art.  Here are a few of the best examples of the complex interactions – and extraordinary feats – of our cross-wired senses.

Calling to See

Bats and dolphins, among other animals, emit sounds into their surroundings —not to communicate with other bats and whales — but to “see” what is around them.  They read echoes of the sound waves, which bounce off objects, to identify and locate objects.

This sensory system is called echolocation. Although most of us can only imagine the pictures that form from sound, some sightless people have managed to master a form of echolocation. By uttering sounds and clicks, these individuals can use their ears to navigate. Some, such as Daniel Kish, have even taught others to use this form of human sonar. Kish once described human echolocation as “something like seeing the world in dim flashes of light.”

Fingers Do the Hearing 

People who are both deaf and blind are incredibly good at using other senses, such as touch, to navigate and understand the world. Some use the Tadoma Speechreading Method to perceive speech by touching the lips of another person as they talk. First taught in the 1920s, lip-reading by touch was a popular form of communication among the deafblind. Helen Keller was one of its early adopters.

If taught early in development, the Tadoma Method can help a deaf-blind child learn to speak as well as to understand others. Those who lose their sight and hearing later in life can use it to read lips.

But because the method is extremely difficult and time consuming to learn, by the 1950s it began to lose ground to American Sign Language as the dominant teaching method. Today, only about 50 people in the world still use of the Tadoma Method.

Still, In ASL, the deaf-blind place their hands over another signer’s hands and follow the motions with their fingers—which is easier because the movements are far less subtle.

Beep Baseball

Blind baseball seems almost impossible to even imagine, but since 1975, when a few blind Minnesotans invented “beep baseball”, those who lack sight have taken part in America’s favorite pastime. Thanks to a one-pound beeping oversized softball and some tweaks to the game, players can hit a home run without ever seeing the ball. They use the sound the ball emits to orient themselves, make contact using a bat and to field.  Special bases make it possible to round the diamond. They might be particularly well-suited to this form of the game, as previous research suggests that blind individuals can more easily localize sounds than sighted people can.

Then there is synesthesia

For a few individuals with a condition called synesthesia, the senses collide dramatically and uniquely to form a kaleidoscope world in which chicken tastes like stars, a symphony smells of fresh baked bread or words are bathed in red, green or purple.

People with synesthesia have a particularly curious cross wiring of the senses in which activating one sense spontaneously triggers another. They see colors when they hear noises, associate particular personalities with days of the week, or hear sounds when they see moving dots.

Synesthesia is thought to be genetic, and recent research even suggests it may confer an evolutionary advantage.  Most synesthetes don’t notice anything strange about the way they perceive their environments until it is brought to their attention.

Given that, at any moment in time, we are bombarded by such a diverse combination of sensory experiences, our appreciation of the individual senses can become somewhat muddled. Our taste experience is affected by the smell, texture and temperature of our food. Similarly, our hearing is said to decrease after overeating, and our sight is affected by noises around us. Sight can also be hampered after eating fatty foods.

Here’s another interesting snippet – if a sad, depressed person tells you their world is dull and grey, and flowers have lost their smell, they’re not just speaking metaphorically. Research shows sensory perception can actually be diminished in depressed individuals.  So focussing on a renewed appreciation of your senses can actually help one get out of an emotional rut.

Five senses? More than ten!

The categorization of our five primary senses (sight, smell, hearing, taste and touch) is attributed to Aristotle. While this basic list is still valid, humans have a number of additional ‘sensory abilities’ not covered above. These secondary senses include:

  • Sense of balance and acceleration– the ability to sense body movement, direction and acceleration, and to maintain balance and equilibrium.
  • Temperature sense– the ability to sense heat and the absence of heat (cold).
  • Sense of Pain– the sense of pain was previously believed to be an overloading of pressure receptors, but it has since been identified as a distinct phenomenon that intertwines with the other senses, including touch.
  • Sense of Time– the ability to perceive the passage of time, both short passages as well as longer time cycles.

We are gifted with a complex system of basic and intertwined senses designed to help us take it all in….If any of these seem a little “off” for you, consider seeing a physician who can help you with a tune up.

14 Injections of Fact and Folklore Surrounding the first “Killed” Vaccine

Just 60 years ago, polio was one of the most feared killers in the U.S.

Every year, as the warmer months approached, panic over polio intensified. Late summer was dubbed “polio season.” Public swimming pools were shut down. Movie theaters urged patrons not to sit too close together to avoid spreading the disease. Insurance companies started selling polio insurance for newborns.

The fear was well grounded. By the 1950s, polio had become one of the most serious communicable diseases among children in the United States. In 1952 alone, nearly 60,000 children were infected with the virus; thousands were paralyzed, and more than 3,000 died. Hospitals set up special units with iron lung machines to keep polio victims alive.

Then in 1955, the U.S. began widespread vaccinations. By 1979, the virus had been completely eliminated across the country. Now polio is on the verge of being eliminated from the world. The virus remains endemic in only two parts of the globe: northern Nigeria and the border between Afghanistan and Pakistan.

On this day, June 23rd, 1995, the creator of the first ever “killed” vaccine, which started the US down the path of eliminating the disease, died. Dr. Jonas Salk was 80 years old. Here are a few facts about the medical genius and the disease he and his colleagues worked to eradicate.

Although polio was the most feared disease of the 20th century, it was hardly the top killer.
The first major polio epidemic in the United States hit Vermont in 1894 with 132 cases. A larger outbreak struck New York City in 1916, with more than 27,000 cases and 6,000 deaths. As the number of polio cases grew, the paralytic disease changed the way Americans looked at public health and disability.

Polio, while definitely on a meteoric rise in the 1950’s, was not the rampant killer it has been portrayed to be. During the 50s and 60s, 10 times as many children died in accidents and three times as many succumbed to cancer. Polio inspired such fear because it struck without warning, and researchers were unsure of how it spread from person to person. In the years following World War II, polls found the only thing Americans feared more than polio was nuclear war.

Salk was rejected by multiple laboratories after medical school.
After graduating from medical school at New York University and completing his residency training, Salk applied to laboratories to work in medical research. Rather than treat patients as a practicing physician, Salk hoped to work on the influenza vaccine, a research area he began studying in medical school.

Although he was rejected from multiple labs, perhaps due to quotas that discriminated against Jewish people, he didn’t get discouraged. “My attitude was always to keep open, to keep scanning. I think that’s how things work in nature. Many people are close-minded, rigid, and that’s not my inclination,” he revealed in his Academy of Achievement interview.

Franklin D. Roosevelt and Harry Truman proved instrumental in the vaccine’s development.
A year after his nomination as a Democratic vice presidential candidate, rising political star Franklin D. Roosevelt contracted polio while vacationing at his summer home on Campobello Island in 1921. The disease left the legs of the 39-year-old future president permanently paralyzed. In 1938, five years after entering the White House, Roosevelt helped to create the National Foundation for Infantile Paralysis, later renamed the March of Dimes Foundation, which became the primary funding source for Salk’s vaccine trials. Employing “poster children” and enlisting the star power of celebrities from Mickey Rooney to Mickey Mouse, the grassroots organization run by Roosevelt’s former Wall Street law partner Basil O’Connor was raising more than $20 million per year by the late 1940s.

In 1946, President Harry Truman declared polio a threat to the United States and called on Americans to do everything possible to combat it. “The fight against infantile paralysis cannot be a local war,” Truman declared in a speech broadcast from the White House. “It must be nationwide. It must be total war in every city, town and village throughout the land. For only with a united front can we ever hope to win any war.”

Science initially failed
Early attempts to develop a vaccine ran into numerous hurdles. A vaccine tested on 10,000 children by two researchers at New York University provided no immunity and left nine children dead. Other vaccine trials used “volunteers” at mental institutions.

Salk challenged prevailing scientific orthodoxy in his vaccine development.
While most scientists believed that effective vaccines could only be developed with live viruses, Salk developed a “killed-virus” vaccine by growing samples of the virus and then deactivating them by adding formaldehyde so that they could no longer reproduce. By injecting the benign strains into the bloodstream, the vaccine tricked the immune system into manufacturing protective antibodies without the need to introduce a weakened form of the virus into healthy patients.

Many researchers, such as Polish-born virologist Albert Sabin, who was developing an oral “live-virus” polio vaccine, called Salk’s approach dangerous. Sabin even belittled Salk as “a mere kitchen chemist.” The hard-charging O’Connor, however, had grown impatient at the time-consuming process of developing a live-virus vaccine and put the resources of the March of Dimes behind Salk.

Since Sabin and Cincinnati Children’s Hospital couldn’t gain political support in the U.S. for what he viewed as his superior vaccine, he moved testing to the Soviet Union instead.

Salk tested the vaccine on himself and his family.
After successfully inoculating thousands of monkeys, Salk began the risky step of testing the vaccine on humans in 1952. In addition to administering the vaccine to children at two Pittsburgh-area institutions, Salk injected himself, his wife and his three sons in his kitchen after boiling the needles and syringes on his stovetop. Salk announced the success of the initial human tests to a national radio audience on March 26, 1953.

The clinical trial was the biggest public health experiment in American history.
On April 26, 1954, six-year-old Randy Kerr was injected with the Salk vaccine at the Franklin Sherman Elementary School in McLean, Virginia. By the end of June, an unprecedented 1.8 million people, including hundreds of thousands of schoolchildren, joined him in becoming “polio pioneers.” For the first time, researchers used the double-blind method, now standard, in which neither the patient nor person administering the inoculation knew if it was a vaccine or placebo. Although no one was certain that the vaccine was perfectly safe—in fact, Sabin argued it would cause more cases of polio than it would prevent—there was no shortage of volunteers.

Salk did not patent his vaccine.
On April 12, 1955, the day the Salk vaccine was declared “safe, effective and potent,” legendary CBS newsman Edward R. Morrow interviewed its creator and asked who owned the patent. “Well, the people, I would say,” said Salk in light of the millions of charitable donations raised by the March of Dimes that funded the vaccine’s research and field testing. “There is no patent. Could you patent the sun?” Lawyers for the foundation had investigated the possibility of patenting the vaccine but did not pursue it, in part because of Salk’s reluctance.

Although a tainted batch of the Salk vaccine killed 11 people, Americans continued vaccinating their children.
Just weeks after the Salk vaccine had been declared safe, more than 200 polio cases were traced to lots contaminated with virulent live polio strains manufactured by the Cutter Laboratories in Berkeley, California. Most taken ill became severely paralyzed. Eleven died. In the haste to rush the vaccine to the public, the federal government had not provided proper supervision of the major drug companies contracted by the March of Dimes to produce 9 million doses of vaccine for 1955. Although the United States surgeon general ordered all inoculations temporarily halted, Americans continued to vaccinate themselves and their children. Outside of the “Cutter Incident,” not a single case of polio attributed to the Salk vaccine was ever contracted in the United States.

A rival vaccine supplanted Salk’s in the 1960s.
Once Sabin’s oral vaccine finally became available in 1962, it quickly supplanted Salk’s injected vaccine because it was cheaper to produce and easier to administer. Ultimately, both vaccines produced by the bitter rivals nearly eradicated the disease from the planet. According to the World Health Organization (WHO), there were only 416 reported cases of polio worldwide in 2013, mostly confined to a handful of Asian and African countries. Since Sabin’s live-virus vaccine, which is responsible for about a dozen cases of polio each year, is seen as the final obstacle to eliminating the disease in most of the world, the WHO has urged polio-free countries to return to Salk’s killed-virus vaccine.

Salk was the stepfather of Pablo Picasso’s Children
In 1970, Salk married Françoise Gilot, a French artist who had two children, Claude and Paloma, with Pablo Picasso. In an interview in 1980, Paloma remembered the fear people had of polio, and that as a child, she didn’t visit her father’s house in the South of France due to a polio outbreak. She also revealed that she got along well with her stepfather: “He’s very cute. He’s a wonderful person,” she said. After his death in 1995, Gilot continued her late husband’s legacy by working at the Salk Institute for Biological Studies.

Salk worked on cures for cancer and AIDS
After Salk developed the polio vaccine, he tried to develop vaccines for cancer, AIDS, and multiple sclerosis. Although he wasn’t ultimately successful, he did patent Remune, a vaccine for AIDS to delay the progression of HIV into AIDS. In 2001, six years after Salk died, Pfizer stopped funding clinical trials for Remune due to a lack of evidence that it worked.

Salk was much maligned by the medical community
At the University of Pittsburgh, Salk launched what was then the largest human trial in history and introduced new scientific rigor now used as the gold standard in development of new treatments and tests for pathology. When it was announced that his vaccine worked, Salk was hailed as a humanitarian hero. By 1957, new polio cases had fallen below 6,000.

While heads of state around the globe rushed to celebrate him, many in the medical community derided his efforts. According to Dr. Charlene Jacobs in a interview with the Oxford Press, this was for many reasons:

  1. He preferred the “killed” vaccine, which most in medicine feared would be too weak.
  2. He worked in secret and with a small team.
  3. They claimed he grabbed the limelight and failed to share credit with others.
  4. It appeared he pandered to the press, crossing an imaginary line medicine had set up between science and the media.

Salk won few awards for what is still considered one of the greatest medical breakthroughs
While nominated several times, he did not win the Nobel Peace prize, and he was blackballed from the Academy of Sciences. He won a great deal of social celebrity, for sure, but his insistence on using intuition as much as rigor left many wondering what he really was doing. His dismissal in actual scientific communities is attributed to envy by many who review the history of the time.

Over the years, polio was found to be a highly contagious disease that spread, not in movie theaters or swimming pools, but from contact with water or food contaminated from the stool of an infected person. Along with the vaccine, much was done to improve hygiene in the Americas, The U.S. recorded its last case of polio in 1979, among isolated Amish communities in several states. Then the effort to eradicate polio globally began in earnest. The Western Hemisphere reported its last case, in Peru, in 1991.

Both Salk’s and Sabin’s vaccines are still used today. Although Jonas Salk is credited with ending the scourge of polio because his killed-virus vaccine was first to market, Albert Sabin’s sweet-tasting and inexpensive oral vaccine continues to prevent the spread of poliomyelitis in remote corners of the world. While the later version, which requires just two drops in a child’s mouth, proved much easier to use in mass immunization campaigns, today, it is being marked as the final barrier to truly eliminating polio – it does occasionally infect patients. The complete return to Salk’s vaccine has been promoted by the World Health Organization (WHO) since 2000.

Advances in medicine sometimes come from great intuition complimented with heavy doses of experience and meaningful development. These three make a powerful elixir. HealthLynked could be that kind of breakthrough – a good mix of real world wisdom, a touch of intuition and a love of professional rigor.

What is the Whipple Procedure – Mayo Clinic

Dr. Horacio Asbun, Mayo Clinic in Florida, explains the Whipple procedure using this animated graphic of a pancreas. Cancer of the pancreas affects 45,000 people every year in the U.S., and it is the fourth leading cause of cancer-related deaths. The five-year overall survival rate if a tumor is detected early and surgically removed is 22 percent, versus 6 percent without early detection and surgery.
