It is well known that people who have lived through traumatic events like sexual assault, domestic abuse, or violent combat can experience symptoms of post-traumatic stress disorder (PTSD), including terrifying flashbacks, severe anxiety, and uncontrollable thoughts about the incident. But what exactly happens in the brains of PTSD patients as they recall these traumatic events?

The Second Plague Pandemic of the mid-14th century, also known as the Black Death, killed 30-60 percent of the European population and profoundly changed the course of European history. New research suggests that this plague, potentially through resulting changes in diet and hygiene, may also be associated with a shift in the composition of the human oral microbiome toward one that contributes to chronic diseases in modern-day humans.

Experiences of discrimination and acculturation are known to have a detrimental effect on a person's health. For pregnant women, these painful experiences can also affect the brain circuitry of their children, a new study finds. These effects, the researchers say, are separate from those caused by general stress and depression. The study was published in the journal Neuropsychopharmacology.

A new study in mice shows that cutting down the amount of a single amino acid called isoleucine can, among other benefits, extend their lifespan, make them leaner and less frail as they age and reduce cancer and prostate problems, all while the mice ate more calories.

Eating more ultra-processed foods (UPFs) may be associated with a higher risk of developing cancers of upper aerodigestive tract (including the mouth, throat and esophagus), according to a new study.  The authors of this international study, which analyzed diet and lifestyle data on 450,111 adults who were followed for approximately 14 years, say obesity associated with the consumption of UPFs may not be the only factor to blame.

This study examined the association between work performance and lifestyle habits among Japanese employees. The results revealed that insufficient sleep was the predominant factor affecting work performance in men and women, followed by lack of regular exercise and eating late-evening meals. Furthermore, the study indicated that men were more likely to exhibit lifestyle habits that impacted work performance than women.

Old people who follow a Mediterranean diet are at a lower risk of cognitive decline, according to a new study. The study provides new evidence for a better understanding of the biological mechanisms related to the impact of the diet on cognitive health in the aging population.

A study found people who have a healthy weight use more energy during the day, when most people are active and eat, while those who have obesity spend more energy during the night, when most people sleep. Researchers also found that, during the day, those with obesity have higher levels of the hormone insulin -- a sign that the body is working harder to use glucose, an energy-packed sugar.

A surprising thing happened when researchers began exploring whether early-life stress compounds the effects of a childhood head injury on health and behavior later in life: In an animal study, stress changed the activation level of many more genes in the brain than were changed by a bump to the head.

Semaglutide reduced cardiovascular events by 20% in adults with overweight or obesity and established cardiovascular disease who do not have diabetes, according to new research.   Semaglutide is primarily prescribed for adults with type 2 diabetes but is also approved for chronic weight management in adults with obesity or overweight and have at least one other health issue. In the trial, patients treated with semaglutide lost an average of 9.4% of their body weight and experienced improvements in other risk factors for cardiovascular disease.   Results from the 'SELECT -- Semaglutide and Cardiovascular Outcomes in Patients with Overweight or Obesity Who Do Not Have Diabetes' trial were presented today during a late-breaking science session at the American Heart Association's Scientific Sessions 2023 and simultaneously published in the New England Journal of Medicine.

Nearly everyone can lower their blood pressure, even people currently on blood pressure-reducing drugs, by lowering their sodium intake, reports a new study. It found 70-75% of all people, regardless of whether they are already on blood pressure medications or not, are likely to see a reduction in their blood pressure if they lower the sodium in their diet.  Losing one teaspoon of salt a day results in systolic blood pressure decline comparable to effect achieved with drugs.
