High-dose oral vitamin D may offer a promising supportive care option for patients experiencing chemotherapy- and radiation-induced skin toxicities, according to a multicenter case series in JAMA Dermatology. Researchers retrospectively evaluated 33 patients treated with high-dose vitamin D (100,000 IU cholecalciferol or ergocalciferol) for toxic erythema of chemotherapy (TEC) or acute radiation dermatitis (ARD) across three academic medical centers between 2021 and 2024.

07/17/2026 Key Takeaways Week 96 visual gains were broadly similar across groups, with mean best-corrected visual acuity improvement ranging from 7.5 to 8.8 letters. The 8 mg regimens were associated with fewer active injections, and 88% and 83% of week 96 completers maintained at least 12-week or 16-week intervals. Central retinal thickness improved across arms, and ocular treatment-emergent adverse events in the study eye occurred at similar rates.

NEXIS Trial Finds No Functional Gain From Early Cycling Plus Amino Acids

07/17/2026 Targeted therapies have transformed outcomes for patients with ALK-positive non-small cell lung cancer (NSCLC), but acquired resistance remains a persistent obstacle. Acquired resistance is often mediated by mutations within the ALK kinase domain, limiting the durability of tyrosine kinase inhibitors (TKIs). Investigators behind the ARCHER trial are pursuing a novel approach aimed not at overcoming resistance after it emerges, but at preventing it from developing in the first place.

07/17/2026 Key Takeaways Traffic-light labels were associated with a higher modified Nutrient Profile Index score in the burger restaurant, while no ecolabel changed that score in the sandwich restaurant. Traffic-light labels were associated with lower greenhouse gas emissions and greater selection of sustainable items in both restaurants, plus lower red-meat selection in the burger restaurant.

07/17/2026 Key Takeaways Lactobacillus recovery increased in both groups, without a statistically significant between-group difference at 10–14 days. Adjunct lactic acid was associated with higher one-week clinical cure and faster relief of malodorous discharge. Six-month recurrence was not lower with adjunct therapy, and adverse effects were limited to mild, tolerable vaginal irritation.

07/17/2026 Key Takeaways Overall postoperative length of stay did not differ significantly across study phases. Compared with baseline, the sustainability phase was associated with faster return to a regular diet and lower in-hospital opioid exposure. In sensitivity analyses, receipt of at least 13 protocol elements was associated with shorter stays and fewer complications, and no clinically significant complications were attributed to the intervention.

07/17/2026 Key Takeaways In-person consultation was associated with higher patient satisfaction than teleconsultation in pooled randomized evidence. ASA physical status reclassification, surgical cancellation, and preoperative anxiety did not differ significantly between groups. Trial sequential analysis suggested the secondary outcomes remained underpowered, with moderate certainty for satisfaction and ASA reclassification and low certainty for the remaining outcomes.

The American Pharmacists Association (APhA) is urging the US Food and Drug Administration (FDA) to prioritize patient safety, scientific evidence, and regulatory oversight in its decision-making process, according to comments submitted to the FDA ahead of the Pharmacy Compounding Advisory Committee (PCAC) review APhA expressed concern over the rapid expansion of unregulated peptide markets, where products are frequently sold online outside established pharmacy and regulatory channels.
