A review finds that antibiotic resistance genes—capable of undermining modern medicine—can travel through the air across both cities and farmland, and argues that airborne spread represents an overlooked public health risk.

A new study, led by researchers at Case Western Reserve University’s School of Medicine, found that vitamin B3 derivatives may be doing more harm than good—helping cancer cells survive and resist treatment.

NCCN brought together more than a thousand oncology professionals at the NCCN 2026 Annual Conference in Orlando, Florida, with hundreds more joining virtually. This year’s event featured educational sessions on the latest breakthroughs in cancer prevention and treatment, clinical guidelines updates, guidance for improving cancer center operations, plus panel discussions on critical issues in care delivery.

With perinatal or birth period depression being linked to maternal well-being and child development, researchers examined whether antibiotic use might be linked to mental health during pregnancy. An analysis of data from approximately 94,000 participants found that antibiotic use before and during early pregnancy was associated with higher odds of psychological distress, with a stepwise pattern observed. The findings may inform discussions about appropriate antibiotic use among women planning pregnancy.

A review in the International Journal of Molecular Sciences, involving researchers from Wroclaw Medical University, suggests that SIBO (small intestinal bacterial overgrowth) may be linked to worsening symptoms of allergic diseases such as asthma, food allergies, and chronic urticaria.

This connection likely involves the gut–immune axis, where disturbances in gut microbiota can influence immune responses. However, the relationship is correlational, not causal, and more research—especially in adults—is needed.

In some patients, diagnosing and treating SIBO may help improve allergy symptoms, particularly when the disease suddenly worsens or does not respond to standard therapy.
