KEY TAKEAWAYS The majority of the world’s people live in what are known as “blood deserts,” areas in which the clinical need for blood components cannot be met in at least 75% of cases. A global coalition of experts led by researchers from the Brigham identified urgent steps that can be taken by health systems to improve access to blood until longer term strategies are established Billions of people live in parts of the world that are so remote from the nearest hospital facility with a functioning blood bank that they are termed “blood deserts.” Researchers  from Brigham and Women’s Hospital, a founding member of the ...

Walking or jogging, yoga, and strength training seem to be the most effective exercises to ease depression, either alone or alongside established treatments such as psychotherapy and drugs, suggests an evidence review published by The BMJ today. Even low intensity activities such as walking or yoga are beneficial, but the results suggest that the more vigorous the activity, the greater the benefits are likely to be. The authors stress that confidence in many of the findings remains low ...

Securing suitable childcare for the irregular and long working hours demanded by a medical career is a crippling financial burden and a draining source of stress for doctor parents, reveals an exclusive snapshot survey by The BMJ today. Some doctors have resigned or are considering resigning, others have changed specialities in the hope that it gives them more flexibility, and yet more altered their plans to have children as a result, reports health journalist Erin Dean. The BMJ Childcare Survey ran on bmj.com from 16 to 30 November ...

Feminist health narratives are being co-opted by commercial interests to market new technologies, tests, and treatments that are not backed by evidence, argue researchers in The BMJ today. Dr Tessa Copp at The University of Sydney and colleagues say such marketing behaviour risks harming women through inappropriate medicalisation, overdiagnosis, and overtreatment. They call for greater wariness of simplistic health messages that any knowledge is power, and urge health professionals and governments ...

Processing times for complaints against drug companies suspected of having breached their industry code of practice have more than tripled in a nearly two-decade period, an investigation by The BMJ has found. Data analysis by Shai Mulinari at Lund University and Piotr Ozieranski at the University of Bath show that the average processing time of a complaint more than tripled between 2004-2021, from less than three months to more than 8.5 months. Numerous complaints have taken more than a year ...

School uniform policies could be restricting young people from being active, particularly primary school-aged girls, new research suggests. The University of Cambridge study used data about the physical activity participation of more than a million five-to-17-year-olds internationally. It found that in countries where a majority of schools require students to wear uniforms fewer young people tend to meet the 60 minutes of physical activity per day recommended by the World Health Organisation (WHO). Regardless of uniform policies, across most countries fewer girls than boys reach those ...

Maryam Shanechi, Dean’s Professor of Electrical and Computer Engineering and founding director of the USC Center for Neurotechnology, and her team have developed a new machine learning method that reveals surprisingly consistent intrinsic brain patterns across different subjects by disentangling these patterns from the effect of visual inputs.The work has been published in the Proceedings of the National Academy of Sciences (PNAS). When performing various everyday movement behaviors, such as reaching for a book, our brain has to take in information, often in the form of visual input — for example, seeing where the book is. Our brain then has to process ...

Every year, around 50,000 people in the United States experience cardiogenic shock — a life-threatening condition, usually caused by a severe heart attack, in which the heart can’t pump enough blood for the body’s needs. Many of these patients end up receiving help from a mechanical pump that can temporarily help the heart pump blood until it recovers enough to function on its own. However, in nearly half of these patients, the extra help leads to an imbalance between the left and right ventricles, which can pose danger to the patient. In a ...

Chronic exposure of human skin to ultraviolet light causes premature aging, or photoaging. As the skin undergoes photoaging, type I collagen bundles, which are found in the dermis beneath the top layer of the skin and provide strength and support to skin, become fragmented. This leads to wrinkles, fragility and loss of support and elasticity.   “The best way to prevent damage to type I collagen by sunlight is to wear sunscreen consistently, daily if possible and particularly when spending time outdoors,” said Frank Wang, MD,  the William B. Taylor Endowed Professor of Clinical Dermatology at U-M Medical School.  Experts ...

Significantly more babies were born on a weekday instead of weekend day or holiday, reveals a large-scale analysis of 21 million births in Japan over almost four decades published February 14, 2024 in the open-access journal PLOS ONE by Miho Sassa from the University of Tokyo, Japan, and colleagues. Medical resources are generally stretched during holidays (including weekends) due to factors like staffing and hospital policies. This may amplify holiday effects: disparities and variations of health outcomes between holidays and weekdays. Dr. Sassa and colleagues studied this holiday effect with a focus on birth, especially high-risk births as measured by babies born preterm ...
