Health Technology: First Successful Tele-Robotic Heart Surgery Performed

From an InterestingEngineering.com online article:

CorPath GRX robot“Remote procedures have the potential to transform how we deliver care when treating the most time-sensitive illnesses such as heart attack and stroke. The success of this study paves the way for large-scale, long-distance telerobotic platforms across the globe, and its publication in Lancet’s EClinicalMedicine demonstrates the transformative nature of telerobotics,” said in a press statement Mark Toland, President and Chief Executive Officer of Corindus Vascular Robotics.

A surgeon in India has performed a series of five percutaneous coronary intervention (PCI) procedures on patients who were on operating tables 32 kilometers (20 miles) away from him. The event marks the first long-distance heart surgery.

The operation was performed in patients who have atherosclerosis, a condition where plaque builds up in the blood vessels and restricts blood flow. In this special remote procedure, a robot called the CorPath GRX robot and controlled by the surgeon inserted a small instrument called a stent in order to open blood vessels in the heart.

Health Studies: Majority Of People With Dementia Never Receive Specialty Diagnosis Or Care

From a USC News online release:

Alzheimer's & Dementia Journal Aug 2019The team found 85% of people first diagnosed with dementia were diagnosed by a non-dementia specialist physician, usually a primary care doctor, and an “unspecified dementia” diagnosis was common.

One year after diagnosis, less than a quarter of patients had seen a dementia specialist. After five years, the percent of patients had only increased to 36%.

In the first large study to examine the diagnosis of dementia in older Americans over time, researchers found the vast majority never meet with a dementia specialist and are instead overwhelmingly diagnosed and cared for by non-specialists.

The study, which also found the use of dementia specialty care was particularly low for Hispanic and Asian patients, was published Wednesday in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.

Health Studies: Early Heart Disease Is Related More To Poor Lifestyle Choices Than Genetics

From a ScienceDaily.com online release:

Eurpean Society of CardiologyPhysical inactivity, smoking, high blood pressure, diabetes, and high cholesterol play a greater role than genetics in many young patients with heart disease, according to research presented today at ESC Congress 2019 together with the World Congress of Cardiology. The findings show that healthy behaviours should be a top priority for reducing heart disease even in those with a family history of early onset.

The study enrolled 1,075 patients under 50, of whom 555 had coronary artery disease (known as premature CAD). Specific conditions included stable angina, heart attack, and unstable angina. The average age was 45 and 87% were men. Risk factor levels and genetics in patients were compared to a control group of 520 healthy volunteers (average age 44, and 86% men). Patients and controls were recruited from the Genes in Madeira and Coronary Disease (GENEMACOR) database.

Five modifiable risk factors were assessed: physical inactivity, smoking, high blood pressure, diabetes, and high cholesterol. Nearly three-quarters (73%) of patients had at least three of these risk factors compared to 31% of controls. In both groups, the likelihood of developing CAD increased exponentially with each additional risk factor. The probability of CAD was 3, 7, and 24 times higher with 1, 2, and 3 or more risk factors, respectively.

Health Studies: High Levels Of Optimism Can Increase Men’s & Women’s Lifespans By Up To 15%

From a PNAS.org online release:

Optimism Study PNASOur results further suggest that optimism is specifically related to 11 to 15% longer life span, on average, and to greater odds of achieving “exceptional longevity,” that is, living to the age of 85 or beyond. These relations were independent of socioeconomic status, health conditions, depression, social integration, and health behaviors (e.g., smoking, diet, and alcohol use). Overall, findings suggest optimism may be an important psychosocial resource for extending life span in older adults.

Participants with highest versus lowest optimism levels had 1.5 (women) and 1.7 (men) greater odds of surviving to age 85; these relationships were maintained after adjusting for health behaviors. Given work indicating optimism is modifiable, these findings suggest optimism may provide a valuable target to test for strategies to promote longevity.

Book Reviews: “Lithium – A Doctor, A Drug, And A Breakthrough” By Walter A. Brown Is “Gripping”

From a Nature Magazine review:

Lithium A Doctor, A Drug, and a Breakthrough Walter A Brown Cover 1He wondered whether lithium could have the same tranquillizing effect on his patients. After trying it out on himself to establish a safe dose, Cade began treating ten people with mania. In September 1949, he reported fast and dramatic improvements in all of them in the Medical Journal of Australia (J. F. J. Cade Med. J. Aus. 2, 349–351; 1949). The majority of these patients had been in and out of Bundoora for years; now, five had improved enough to return to their homes and families.

Lithium: A Doctor, a Drug, and a Breakthrough Walter A. BrownLiveright (2019)

Some 70 years ago, John Cade, an Australian psychiatrist, discovered a medication for bipolar disorder that helped many patients to regain stability swiftly. Lithium is now the standard treatment for the condition, and one of the most consistently effective medicines in psychiatry. But its rise was riddled with obstacles. The intertwined story of Cade and his momentous finding is told in Lithium, a compelling book by US psychiatrist Walter Brown.

Healthcare Update: Health-Professions Students And Workers Are “Exhausted And Sick”

From a Scientific American online article:

Scientific American - Getty ImagesHealth care is a big business, and our system reimburses hospitals and health care workers for caring for the sickest people rather than healthiest ones. This process depletes healers’ energy and often causes them to become exhausted and sick. That means all of us who work in or study to work in health care are at risk. To break this vicious cycle, we need self-scrutiny and willingness to change.

Health-professions students and workers live in chronically stressful environments—responsible for an increasingly sick population, which they are expected to repeatedly rescue from failure. To heal others, our health care professionals need healing themselves.

American medical students, physicians and nurses: There’s good news and bad news.

The bad news is that our health care system and many of its workers are sick. The good news is that we can heal them. We should waste no time in starting.

Memory Research: Ability To Forget Is Crucial To How The Brain Works

From a Nature.com online article:

Nature Outlook The Brain“What is memory without forgetting?” asks Oliver Hardt, a cognitive psychologist studying the neurobiology of memory at McGill University in Montreal, Canada. “It’s impossible,” he says. “To have proper memory function, you have to have forgetting.”

A growing body of work, cultivated in the past decade, suggests that the loss of memories is not a passive process. Rather, forgetting seems to be an active mechanism that is constantly at work in the brain. In some — perhaps even all — animals, the brain’s standard state is not to remember, but to forget. And a better understanding of that state could lead to breakthroughs in treatments for conditions such as anxiety, post-traumatic stress disorder (PTSD), and even Alzheimer’s disease.

Health Care: Researchers Have Developed “Fast-Acting” Skin Patch To Attack Melanoma Cells

From a ScienceDaily.com online article:

American Chemical Society Skin Patch to attack Melanoma cellsNow, researchers have developed a fast-acting skin patch that efficiently delivers medication to attack melanoma cells. The device, tested in mice and human skin samples, is an advance toward developing a vaccine to treat melanoma and has widespread applications for other vaccines.

Nearly 100,000 new cases of melanoma are diagnosed annually, and 20 Americans die every day from it. Now, researchers have developed a skin patch that efficiently delivers medication within one minute to attack melanoma cells. The device, tested in mice and human skin samples, also could be adapted to deliver other vaccines.

“Our patch has a unique chemical coating and mode of action that allows it to be applied and removed from the skin in just a minute while still delivering a therapeutic dose of drugs,” says Yanpu He, a graduate student who helped develop the device. “Our patches elicit a robust antibody response in living mice and show promise in eliciting a strong immune response in human skin.”

Health Issues: Middle-Aged Man With Rapid Heart Beat Diagnosed With Sarcoidosis

From a New York Times article by Lisa Sanders, M.D.:

Diagnosis from New York Times by Lisa Sanders, MD Photo Illustration by Ina JangIn sarcoidosis, abnormal collections of cells called granulomas invade the organ, interfering with its normal activity and often destroying the surrounding tissue. What is left is a scar, known as fibrosis, dotted with these abnormal granulomas.

When caught early, sarcoidosis can be treated and the destruction slowed or even stopped. But it was too late for that in this man’s case. He was started on immune-suppressing medications to prevent additional damage, but he needed a new heart.

The man had been active and healthy, until five years earlier when he started to feel tired. His doctor sent him to a cardiologist, who took one look at his EKG and said he needed a pacemaker, right away. He got one the next day. He was fine for a year, and then, on a business trip to Atlanta, he suddenly felt lightheaded, and his heart fluttered wildly in his chest. In the E.R. they told him his heart was beating 220 beats a minute. You should be dead, one doctor said.

Drug Studies: Polypill Strategy (Including Aspirin) Proves “Effective In Preventing Major Cardiovascular Events”

From The Lancet issue August 24, 2019:

Polypill illustration from Harvard HealthUse of polypill was effective in preventing major cardiovascular events. Medication adherence was high and adverse event numbers were low. The polypill strategy could be considered as an additional effective component in controlling cardiovascular diseases, especially in LMICs.

When restricted to participants in the polypill group with high adherence, the reduction in the risk of major cardiovascular events was even greater compared with the minimal care group…

A fixed-dose combination therapy (polypill strategy) has been proposed as an approach to reduce the burden of cardiovascular disease, especially in low-income and middle-income countries (LMICs). The PolyIran study aimed to assess the effectiveness and safety of a four-component polypill including aspirin, atorvastatin, hydrochlorothiazide, and either enalapril or valsartan for primary and secondary prevention of cardiovascular disease.
