Teenagers across the country are getting less sleep, a researcher from the University of Connecticut reports on March 2 in JAMA. And the problem appears to be societal. Teens not getting enough sleep has been reported as a problem in the medical literature since at least the turn of the 20th century: a 1905 study in The Lancet of the sleep hours of boys in British boarding schools worried that they were not getting enough sleep due to nighttime lighting, and suggested that “late to bed and early to rise is neither physiological nor wise”. ...

A year after stopping taking weight loss drugs such as Ozempic and Wegovy, people regain on average 60% of their lost weight – but beyond this, their weight regain plateaus, with individuals managing to keep off 25% of the weight lost to treatment, say researchers at the University of Cambridge. It isn’t clear, however, whether the weight regain constitutes both fat and muscle, or mainly fat. Previous studies have suggested that lean body mass – including muscle – can constitute up to 40% of total weight lost during treatment. More than a billion people worldwide ...

Glucagon-like peptide-1 (GLP-1) receptor agonists used to treat type 2 diabetes and obesity may also help to lower the risk of addiction to a range of substances including alcohol, cannabis, cocaine, nicotine, and opioids, finds a large US study published by The BMJ today. GLP-1 receptor agonists were also associated with reduced risks of adverse outcomes such as overdoses and drug-related emergency department visits and deaths in people with pre-existing substance use disorders, the results show. Some studies suggest that GLP-1 receptor agonists ...

As the UK government considers adding health warnings to new wood burning stoves, as part of a public consultation on solid fuel burning, councils in England are being threatened with legal action for running public health campaigns warning against their use, reveals an investigation published by The BMJ today. Freedom of Information requests show that just under a third of the 50 councils in England with the highest concentration of wood burning stoves had been threatened with legal action or lobbied by the Stove Industry Association (SIA). Other local authorities have received leaflets from the main stove ...

Researchers at Washington University School of Medicine in St. Louis show in a new study that GLP-1 medications may be effective at treating and preventing substance use disorders across all major addictive substances studied, suggesting these drugs target a common biological pathway underlying addiction.  From their beginnings as a treatment for type 2 diabetes, GLP-1 receptor agonists such as semaglutide and tirzepatide have seen an explosion in use, most popularly for weight loss. Patients have reported decreased interest in alcohol and nicotine when taking GLP-1s, and observational studies have shown an association between ...

A new international study published in The Lancet eClinicalMedicine has mapped global blood transfusion practices for life-threatening abdominal injuries, highlighting significant variation in care worldwide and opportunities for health systems to learn from one another. The research, led by the University of Cambridge as part of the GOAL-Trauma study, analysed data from 1,768 patients treated in 187 hospitals across 51 countries. It represents the first multicentre international study to report on blood transfusion strategies for patients undergoing emergency abdominal surgery following trauma (trauma laparotomy). Uncontrolled bleeding is the leading cause of death following ...

31% of Gen Z men agree that a wife should always obey her husband and one third (33%) say a husband should have the final word on important decisions, according to a new global study of 23,000 people.   Gen Z men (born between 1997 and 2012) were twice as likely as Baby Boomer men (born between 1946 and 1964) to have traditional views on decision-making within a marriage, with just 13% and 17% of Baby Boomer men agreeing with those statements respectively.  By contrast, far fewer Gen Z women agreed that a wife should always obey her husband (18%) and ...

In the three-and-a-half years since the U.S. Supreme Court overturned the constitutional right to an abortion in Dobbs v. Jackson Women’s Health Organization, the fragmented state of abortion access has put medical professionals in a precarious position. Many states have tightened abortion restrictions, with some enacting criminal penalties up to life in prison for physicians who perform abortions. Medical schools have curtailed abortion-related curricula. New research led in part by the University of Washington found that the new restrictions are not only affecting the current medical workforce — they may ...

URBANA, Ill. – Fried foods are popular with consumers, but their high fat content can contribute to health challenges like obesity and hypertension. If the food industry can offer lower-fat options of similar quality, people can more easily make health-conscious food choices. Researchers at the University of Illinois Urbana-Champaign have explored microwave frying of French fries, providing insights that can help food manufacturers modify their production methods. They propose combining conventional frying with microwave frying to provide the desired crispiness and texture while reducing the cooking time and oil absorption. “Consumers ...
