Researchers developed a potential new treatment for alopecia areata, an autoimmune disorder that causes hair loss. The microneedle patch delivers immune-regulating molecules that can teach T cells not to attack hair follicles, helping hair regrow.

Just a few days on a night shift schedule throws off protein rhythms related to blood glucose regulation, energy metabolism and inflammation, processes that can influence the development of chronic metabolic conditions. The finding provides new clues as to why night shift workers are more prone to diabetes, obesity and other metabolic disorders. Though more research is needed, the researchers said the study shows that these disrupted rhythms can be seen in as little as three days, which suggests early intervention to prevent diabetes and obesity is possible. Such intervention could also help lower the risk of heart disease and stroke, which is elevated in night shift workers as well.

Aging clocks can measure the biological age of humans with high precision. Biological age can be influenced by environmental factors such as smoking or diet, thus deviating from the chronological age that is calculated using the date of birth. The precision of these aging clocks suggests that the aging process follows a program. Scientists have now discovered that aging clocks actually measure the increase in stochastic changes in cells.

Researcher found that exposed individuals with confirmed TB infection -- i.e. a positive skin or blood test -- should receive priority treatment in settings with a low prevalence of the disease, regardless of their age. However, in high-burden settings, all exposed individuals should be considered for preventative treatment, even without a confirmed infection. This strategy can help end the tuberculosis epidemic and support global public health efforts to reduce TB mortality by 95 percent by 2035 (from 2015 estimates).

Neuropathy, the nerve damage that causes pain and numbness in the feet and hands and can eventually lead to falls, infection and even amputation, is very common and underdiagnosed, according to a new study.

A tiny, flexible electronic device that wraps around the spinal cord could represent a new approach to the treatment of spinal injuries, which can cause profound disability and paralysis. A team of engineers, neuroscientists and surgeons developed the devices and used them to record the nerve signals going back and forth between the brain and the spinal cord. Unlike current approaches, the new devices can record 360-degree information, giving a complete picture of spinal cord activity.

Experts released a new clinical guideline for effectively managing individuals diagnosed with hypertrophic cardiomyopathy (HCM). The guideline reiterates the importance of collaborative decision-making with patients who have HCM and provides updated recommendations for the most effective treatment pathways for adult and pediatric patients.

Adolescents who view their households as more unstructured, disorganized, or hectic than their siblings develop more mental health and behavioral problems in early adulthood, according to new research.

New research suggests a 'tailored vaccine' might hold the key to treating bacteria-driven flares of eczema in children. The team has taken several leaps forward in understanding how the immune response works in cases of eczema driven by the common, troublesome Staphylococcus aureus bacterium, and in doing so they have identified new cellular targets for a vaccine.

Researchers have found evidence of the molecular causes of the damaging impact heat stress causes on the gut, liver and brain in the elderly. These findings point to the potential of developing precise prognostic and therapeutic interventions.

Starting people with opioid use disorder on extended-release, injectable naltrexone (XR-naltrexone) within five to seven days of seeking treatment is more effective than the standard treatment method of starting within 10-15 days, but requires closer medical supervision, according to results from a clinical trial. The findings suggest that this rapid treatment protocol could make XR-naltrexone more viable as a treatment option for opioid use disorder, which continues to take lives at an alarming rate.

An estimated 321,566 children in the United States lost a parent to drug overdose from 2011 to 2021, according to a new study. The rate of children who experienced this loss more than doubled during this period, from approximately 27 to 63 children per 100,000. The highest number of affected children were those with non-Hispanic white parents, but communities of color and tribal communities were disproportionately affected.

A study has found the widespread impact of child abuse and neglect, with analysis suggesting they cause nearly half of common mental conditions. Researchers say childhood maltreatment should be treated as a public health priority.

Researchers have shed valuable light on the complex mechanisms by which a class of psychedelic drugs binds to and activates serotonin receptors to produce potential therapeutic effects in patients with neuropsychiatric disorders such as depression and anxiety.
