Injections of botulinum toxin, commonly known as Botox, could be an effective and well-tolerated option for treating debilitating complications caused by reduced blood flow to the fingers, such as acute digital ischemia (which makes the fingers very painful, cold and sometimes white or bluish), digital ulcers (open wounds that heal poorly), and gangrene, according to a study recently published in JAMA Dermatology.

Could wounded skin someday regrow perfectly without scars? A new study by Harvard stem cell biologists published in Cell reveals a way to fully regenerate skin by unblocking an embryonic healing mechanism that shuts off after birth. Demonstrated on mice, the study suggests a potential means to develop similar therapies in human patients.

Nationally, heat-related mortality has risen by nearly 17% per year since 2016. As a result, New York City now issues heat alerts and opens cooling centers when the heat index is forecast to reach 95 degrees Fahrenheit or higher for at least two consecutive days or a heat index of 100 degrees Fahrenheit or higher for any length of time. Meanwhile, older adults are known to have a higher risk of heat stroke and related death, to have more heat-sensitive chronic conditions such as heart disease, kidney disease, and diabetes, and to be more likely to take medications that impair heat regulation.

Losing health insurance can quickly worsen health for people with diabetes as patients struggle to control the disease after coverage is interrupted, according to new research from Oregon Health & Science University.

Osteoarthritis, a condition that causes pain and reduced mobility in joints such as the knees and fingers, is one of the most common joint disorders worldwide, particularly among aging populations. The disease is characterized by the gradual breakdown of cartilage, which normally cushions the bones within joints.
