Most people cycle and regain weight
Most people lose, gain and maintain their weight inconsistently, and those who lose the most weight are most likely to keep it off and keep losing, new research reports.
Researchers find 'simple' methods to prevent heart attacks and stroke worldwide
Three studies were published today in the New England Journal of Medicine.
Oxytocin nasal spray improves self-control in overweight men
A single dose of oxytocin nasal spray, known to reduce food intake, decreases impulsive behavior in overweight and obese men, according to a preliminary study to be presented Saturday at the Endocrine Society's 98th annual meeting in Boston.
Liraglutide may make high-fat foods less desirable to the brain's reward centers
A new study finds that the diabetes drug liraglutide leads to weight loss by acting on an area of the brain that controls attention and possibly making desirable foods less rewarding.
Penn researchers find similar outcomes for patients with severe aortic stenosis who undergo transcatheter aortic valve replacement or surgery
In this first randomized clinical trial for intermediate-risk patients with severe, symptomatic AS, conducted by researchers in the Perelman School of Medicine at the University of Pennsylvania, in partnership with Edwards Lifesciences, the Cardiovascular Research Foundation, and 56 centers across the United States and Canada, investigators found that TAVR with SAPIEN XT resulted in similar two-year clinical outcomes, as compared to surgical aortic valve replacement.
More dietary calcium may lower risk of cardiovascular disease
In older people, higher dietary calcium intake may lower the risk of cardiovascular disease, but not of stroke and fracture, new research from South Korea suggests.
Improving depression symptoms can reduce risk of major cardiovascular problems, new study finds
a new study by researchers at the Intermountain Medical Center Heart Institute in Salt Lake City found that effectively treating depression can reduce a patient's chance of having a stroke, heart failure, a heart attack or death.
Low levels of two components of vitamin D can help predict risk of heart attack
Low levels of total vitamin D and bioavailable vitamin D can help predict a person's risk of major adverse cardiovascular events such as a heart attack, stroke, heart failure or death, according to a first-of-its-kind study from the Intermountain Medical Center Heart Institute in Salt Lake City.
Tanning may protect skin against harmful UV irradiation but block vitamin D synthesis
As skin tans, it darkens to protect itself against harmful ultraviolet (UV) radiation, but the increasing pigment blocks vitamin D synthesis, limiting the skin's ability to produce more vitamin D, a new study from Brazil finds.
Study investigates light, biological clocks, estrogen receptor expression in the breast
Researchers are exploring one possible physiologic explanation of why prior studies have demonstrated a higher risk of breast cancer in women who experience high levels of illumination at night.
New procedure could improve success rate of cell transplant to cure type 1 diabetes
New research suggests pretreating cells with a peptide hormone may improve the success rate of pancreatic islet cell transplants, a procedure that holds great promise for curing type 1 diabetes.
Large whey protein breakfast may help manage type 2 diabetes
A large breakfast containing whey protein may help manage type 2 diabetes, new research from Israel reports.
Dual device-drug therapy improves uncontrolled diabetes and obesity
Combining a temporary one-year intestinal bypass device with the drug liraglutide helps patients lose weight and improve their diabetes control better than using either the device or the drug alone, new research from the United Kingdom reports.
Age and gender influence risk for certain peripheral vascular diseases
New findings from large-scale studies of more than 3.6 million people who underwent screening for cardiovascular disease reveals that a person's age and gender affects the prevalence of certain types of peripheral vascular diseases (PVD), and that diabetes is a major risk factor for developing these diseases, even in patients without heart disease.
Rates of death and stroke equivalent for surgery and TAVR at 2 years
Intermediate-risk patients with severe aortic stenosis who receive minimally invasive transcatheter aortic valve replacement, known as TAVR, have similar rates of death and disabling strokes after two years compared with those undergoing standard open heart surgical replacement, according to a study presented at the American College of Cardiology's 65th Annual Scientific Session.
Building a better concussion test
Researchers from San Diego State University have developed an inexpensive, ultraportable balance board called BTrackS that provides fast, objective feedback on an athlete's balance disruption following a suspected concussion.
Radioactive iodine treatment in women affects ovarian reserve and may affect fertility
Women of reproductive age who have thyroid cancer should be cautious about receiving radioactive iodine treatment, which affects their remaining egg supply -- their ovarian reserve -- and may affect their fertility, new research from Israel finds.
Pituitary insufficiency is prevalent after blast concussion in military veterans
A study in military veterans finds that explosive blast-related concussions frequently result in hormone changes leading to problems such as sleep disturbances, fatigue, depression and poor quality of life.
Common flame retardant chemical disrupts a hormone that is essential to life
Brominated fire retardants, used in many consumer products and known to cause hormonal irregularities, overstimulates an adrenal gland hormone in a way that may lead to the development of cardiovascular disease, new research in human cells finds.

Dispatch 6: Strange Times
Covid has disrupted the most basic routines of our days and nights. But in the middle of a conversation about how to fight the virus, we find a place impervious to the stalled plans and frenetic demands of the outside world. It's a very different kind of front line, where urgent work means moving slow, and time is marked out in tiny pre-planned steps. Then, on a walk through the woods, we consider how the tempo of our lives affects our minds and discover how the beats of biology shape our bodies. This episode was produced with help from Molly Webster and Tracie Hunte. Support Radiolab today at Radiolab.org/donate.
