This month marks 266 years since the birth of one of the most celebrated names in medical discovery. Edward Jenner, credited with the discovery of the smallpox vaccination, was born on 17 May 1749 (6 May by the Julian calendar, still in use in England by a quirk of anti-papal authoritarianism until 1752) in the village of Berkeley in Gloucestershire, England.
It is now two years since the publication of DSM-5. As one might expect when a widely used manual is revised, some mental health clinicians were worried they would have to learn diagnosis from scratch.
Things move fast at the acute end of medicine – and nowhere is this more apparent than in the field of intensive and acute cardiovascular care. This important field has been somewhat neglected at the expense of super-subspecialisation in cardiology. But times are changing.
There has been an ongoing battle to end homelessness in the United States, particularly among veterans. Over the past three decades, considerable research has been conducted to identify risk factors for veteran homelessness, and the Department of Veterans Affairs (VA) has funded much of that research. In 2009, the Department of Veterans Affairs (VA) announced its commitment to end veteran homelessness in five years. As we near the end of that five years, it’s important to reflect on what we have learned and what we now know about veteran homelessness.
Considerable evidence has linked an unhealthy diet to obesity, metabolic syndrome, diabetes and cancer. We now understand how chronic obesity ages us and then underlies the foundation of our death. Furthermore, obesity leads to body-wide chronic inflammation that predisposes us to depression and dementia. However, these are all the long-term consequences of our diet upon our body and brain.
A red open car blasts past you, exhaust and radio blaring, going at least 10 miles faster than the speed limit. Want to take a bet on the driver? Well, you won’t get odds. Everyone knows the answer. All that exhibitionism shouts out the commonplace, if not always welcome, features of young males. Just rampant testosterone, you might say. And that’s right. It is testosterone. The young man may be driving the car but testosterone is what’s driving him.
How sharp is your medical lexicon? Even experienced professionals may be stumped by these obscure terms! Definitions are drawn from the Dictionary of Nursing and the Oxford Concise Medical Dictionary on Oxford Reference.
Throughout history, nurses have been the unsung heroes of the medical profession. President Dwight D. Eisenhower, for instance, refused to proclaim a “Nurses’ Day” at the request of Dorothy Sutherland, an official with the US Department of Health, Education, and Welfare in 1953. More than two decades later, however, the International Council of Nurses (ICN), succeeded in establishing International Nurses Day on the anniversary of the birth of Florence Nightingale, a 19th century wartime nurse considered the founder of modern nursing.
On this day in 1863, General Thomas J. “Stonewall” Jackson, one of the wiliest military commanders this country ever produced, died eight days after being shot by his own men. He had lost a massive amount of blood before having his left arm amputated by Dr. Hunter Holmes McGuire, arguably the most celebrated Civil War surgeon of either side.
Our actions, thoughts, perceptions, feelings, and memories are underpinned by electrical activity, which passes through networks of neurons in the brain. As a child grows and gains new skills their brain changes rapidly and brain networks are formed and strengthened with learning and experience.
Osteoarthritis is a chronic condition of the synovial joint. The disease develops over time and most commonly affects the knees, hips and hands, and less commonly the shoulder, spine, ankles and feet. It’s a prevalent, disabling disease, and consequently has a formidable individual and social impact.
As 2.6 million men and women return home from war, the prevalence of veteran suicide and post-traumatic stress is something that is frequently discussed by civilians, politicians, and the media, but seldom understood. These changes extend beyond psychological readjustment, physical handicap, and even loss of life. The greatest wounds, in fact, may not even be visible to the naked eye. While the traditional dialogue concerning veteran assistance typically involves the availability of institutional services, military hospitals, and other resources, there is an increasing need to address what many call the “moral injuries” sustained by soldiers during combat.
The Obamacare “Cadillac tax” is currently scheduled to go into effect in 2018. However, last week, sixty-six members of the House of Representatives, including both Republicans and Democrats, proposed to repeal the Cadillac tax before it becomes effective. The Cadillac tax will be imposed at a 40% rate on the cost of health care insurance, exceeding statutorily-established thresholds. Unions and many of their Democratic stalwarts, otherwise supportive of Obamacare, oppose the Cadillac tax because generous union-sponsored health care plans will trigger the tax.
Given the highly scientific and technical nature of medical practice, it is tempting to assume that the system of residency training developed in response to intellectual forces within medicine. There is much truth to this. After all, the need to learn scientific concepts and principles, to develop skills of critical reasoning, to acquire the capacity to manage uncertainty, to master technical procedures, and to learn how to assume responsibility for patient care all reflected powerful professional demands.
In our study analyzing data from the New England Centenarian Study, we found that for people who live to 90 years old, the chance of their siblings also reaching age 90 is relatively small – about 1.7 times greater than for the average person born around the same time.
Today, 25 April is a joint celebration for geneticists, commemorating the discovery of the helix nature of DNA by James Watson and Francis Crick in 1953 and the completion of the human genome project fifty years later in 2003. It may have taken half a century to map the human genome, but in the years since its completion the field of genetics has seen breakthroughs increase at an ever-accelerating rate.
