Study finds large gap in breast cancer treatment recommendations for patients aged 70 vs 69

Researchers analyzed over 500,000 patient records and found that patients diagnosed at age 70 were nearly twice as likely to be passed over for post-surgical radiation therapy. This significant gap in treatment recommendations suggests that cognitive heuristics play a major role in physician decision-making.

Scientists document two separate reservoirs of latent HIV in patients

Researchers have identified a distinct latent reservoir of HIV-infected CD4+ T cells in the central nervous system (CNS), separate from the latent reservoir in blood and lymph tissue. This finding highlights a new challenge in creating a cure for HIV, as any curative therapy would need to activate both dormant reservoirs.
