VITAMIN SUPPLEMENT SLOWS GLAUCOMA Researchers at Karolinska Institute found that when mice with glaucoma were given a supplement containing vitamins B6, B9, and B12, as well as choline, their glaucoma developed more slowly, and damage to the optic nerve was completely halted. The researchers had observed that levels of the amino acid homocysteine were elevated in people with glaucoma, and the ability of their retinas to use certain vitamins was slowed. “Altered homocysteine levels may reveal that the retina has lost its ability to use certain vitamins that are necessary to maintain healthy metabolism,” said James Tribble, Ph.D. As a result of their study, researchers are starting a clinical trial that includes patients with both primary open-angle glaucoma (slower progression) and pseudoexfoliation glaucoma (faster progression).
HIV DRUGS PROTECT AGAINST ALZHEIMER’S People who take HIV drugs called NRTIs have a substantially lower risk of developing Alzheimer’s disease than those who do not take the drugs. NRTIs, or nucleoside reverse
transcriptase inhibitors, keep the virus from replicating in the body. But researchers at the University of Virginia Health System found that NRTIs can prevent the activation of inflammasomes, proteins that have been
implicated in the development of Alzheimer’s. “Our results suggest that taking these drugs could prevent approximately 1 million new cases of Alzheimer’s disease every year,” said Jayakrishna Ambati, M.D. A new inflammasome- blocking drug called K9, which is a safer and more eff ective
version of NRTIs, is already in clinical trials for other diseases.
ANTIDEPRESSANTS MAY FIGHT CANCER Selective serotonin reuptake inhibitors (SSRIs) could help the immune system fight cancer, according to a UCLA study published in Cell. SSRIs, which include Prozac, Zoloft, and Paxil, substantially improved the ability of T cells to fight cancer and suppress tumor growth. Researchers tested SSRIs in mouse and human tumor models of melanoma, breast, prostate, colon, and bladder cancer. They found the treatment reduced average tumor size by over 50% and made the cancer-fighting T cells more eff ective at killing cancer cells.
MENTHOL-FLAVORED CIGARETTES INCREASE MORTALITY RISK A study by the American Cancer Society found that people who smoke menthol cigarettes have a higher risk of dying from any cause and heart disease than those who smoke non-menthol cigarettes.

EXTREME SUMMER HEAT SPEEDS
BIOLOGICAL AGING Extreme heat may
accelerate biological aging in older adults, according to researchers at the University of Southern California. They examined blood samples taken at various
times from more than 3,600 adults aged 56 and older
over six years, and analyzed them for epigenetic changes, or changes in the way individual genes are turned “off ” or “on” by a process called DNA methylation. The researchers used mathematical tools called epigenetic clocks to estimate biological ages at each time point. They then compared participants’ changes in biological age to their location’s heat index history and number of high heat days reported by the National Weather Service. Days reaching between 90°F and 103°F were classified as “extreme caution.” “Participants living in areas where high heat days, as defined as ‘extreme caution’ or higher levels, occur half the year, such as Phoenix, Arizona, experienced up to 14 months of additional biological aging compared to those living in areas with fewer than 10 heat days per year,” said Eunyoung Choi, Ph.D.
