Disparities seen in treatment of middle ear infections in US children

Children from socially disadvantaged backgrounds are less likely to receive treatment for otitis media and more likely to experience complications from undertreatment, according to a study published online Nov. 10 in JAMA Otolaryngology-Head & Neck Surgery. To quantify social disparities in treatment patterns, Z. Jason Qian, M.D., and David H. Rehkopf, Sc.D., M.P.H., both from […]

Researchers recreate the adrenal gland in a petri dish

Sitting atop the kidneys, the adrenal gland plays a pivotal role in maintaining a healthy body. Responding to signals from the brain, the gland secretes hormones that support critical functions like blood pressure, metabolism, and fertility. People with adrenal gland disorders—such as primary adrenal insufficiency, in which the gland does not release sufficient hormones—can suffer […]

A comparative analysis of leg morphology between sprinters and non-sprinters reveals surprising results

A comprehensive knowledge of human biomechanics is useful for training athletes more effectively. From a biomechanical perspective, sprinting is challenging in comparison to walking and endurance running, making it an intriguing area of research. In addition, a detailed biomechanical understanding of sprinter limbs can be insightful for more effective training of sprinters and for advancing […]

People don’t mate randomly but this flawed assumption informs many studies linking genes to diseases and traits

The idea that correlation does not imply causation is a fundamental caveat in epidemiological research. A classic example involves a hypothetical link between ice cream sales and drownings—instead of increased ice cream consumption causing more people to drown, it’s plausible that a third variable, summer weather, is driving up an appetite for ice cream and […]

A simplified measurement method for determining immune age improves analysis of cardiorespiratory fitness

Both the functionality of the immune system and cardiorespiratory fitness (CRF) play an important role in a person’s health and work ability. Researchers at the Leibniz Research Centre for Working Environment and Human Factors in Dortmund (IfADo) have analyzed the influence of immune age on cardiorespiratory fitness in more detail. The immunology team has succeeded […]
