From a New York Times online article:
If one geriatrician can care for 700 patients with complicated medical needs, as a federal model estimates, then the nation will need 33,200 such doctors in 2025. It has about 7,000, only half of them practicing full time. (They’re sometimes confused with gerontologists, who study aging, and may work with older adults, but are not health care providers.)
Geriatrics became a board-certified medical specialty only in 1988. An analysis published in 2018 showed that over 16 years, through academic year 2017-18, the number of graduate fellowship programs that train geriatricians, underwritten by Medicare, increased to 210 from 182. That represents virtually no growth when adjusted for the rising United States population.
“It’s basically stagnation,” said Aldis Petriceks, the study’s lead author, now a medical student at Harvard.
WHO’s definition of health is famously “a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity”. One of the oldest medical texts we know of, The Science of Medicine attributed to Hippocrates, sets out the goal of medicine in comparable terms: “the complete removal of the distress of the sick”.

to a paper Mattson and colleagues published in February in the experimental biology journal FASEB. In humans, fasting for 12 hours or more drops the levels of glycogen, a form of cellular glucose. Like changing to a backup gas tank, the body switches from glucose to fatty acids, a more efficient fuel. The switch generates the production of ketones, which are energy molecules that are made in the liver. “When the fats are mobilized and used to produce ketones, we think that is a key factor in accruing the health benefits,” says Mattson.
“This is an entirely new approach with no current treatments able to change scar in this way,” says Associate Professor James Chong who led the research. “By improving cardiac function and scar formation following heart attack, treatment with rhPDGF-AB led to an overall increase in survival rate in our study.”



At the moment, about two-thirds of Americans do not meet the standard exercise guidelines of about 30 minutes a day of moderate exercise, such as walking.
surgery, chemotherapy and radiation. We spend $150 billion each year treating cancer, yet a patient with cancer is as likely to die of it today — with a few exceptions — as one was 50 years ago. Today we spend the hour with renowned cancer doctor, Dr. Azra Raza, author of the new book, “The First Cell: And the Human Costs of Pursuing Cancer to the Last.” She argues that experiments and the funding for eradicating cancer look at the disease when it is in its later stages, when the cancer has grown and spread. Instead, she says, the focus should be on the very first stages — the first cell, as her book is titled. She says this type of treatment would be more effective, cheaper and less toxic.
…the researchers demonstrated that the biggest drop in cognitive ability occurs at the slightest level of hearing loss — a decline from zero to the “normal” level of 25 decibels, with smaller cognitive losses occurring when hearing deficits rise from 25 to 50 decibels.
