Many older adults, particularly older women, use over-the-counter supplements for antiaging benefits, including for hair and skin. The supplement industry is unregulated by the Food and Drug Administration, and the interactions between supplements and medications are often overlooked by both patients and physicians. This article discusses the proposed mechanism of action, common misconceptions, possible benefits, and potential side effects of the most commonly used antiaging skin supplements by women, including biotin, nicotinamide, hyaluronic acid, collagen, zinc, vitamin C, vitamin A, vitamin E, and other antioxidants. Supplements may also interfere with common blood tests, such as biotin with the thyroid and troponin cardiac enzyme tests, which patients and their clinicians must be aware of and account for when interpreting lab results. Other supplements, such as zinc, are commonly taken in excess and may result in deficiencies in the absorption of other minerals, such as copper. Over-supplementation of fat-soluble vitamins, such as vitamin A and vitamin E, can result in toxic levels since excess is not excreted in the urine. The clinician caring for older patients’ skin and nails must ask older patients about supplement use and be aware of the potential harms of these supplements in some patients.

By recognizing imaging patterns associated with opportunistic organisms in immunocompromised patients, radiologists can narrow the differential diagnosis and expedite treatment, reducing morbidity and mortality rates in immunocompromised patients at risk.

Importance Accurate classification and reliability in assessment for lesions of hidradenitis suppurativa (HS) by investigators is critical to the determination of responder status and to overall data quality in clinical trials. Objective To establish consensus-based morphological definitions of HS lesions and guidance statements that standardize investigator lesion assessments for implementation in clinical trials. Evidence Review Health professionals (primarily dermatologists) with expertise in the measurement of HS disease activity as well as novice raters completed a preliminary questionnaire in which participants were asked to assess images of HS lesions and provide qualitative feedback on their decision making. Based on this feedback, detailed morphologic definitions for lesions and guidance statements that standardize lesion assessments were formulated and presented for consensus voting in 2 electronic Delphi surveys. A virtual group discussion after round 1 supported participants in round 2 voting. Findings Response rates were 84.7% (50 of 59), 86.0% (43 of 50), and 90.9% (40 of 44) in the preliminary, electronic Delphi round 1, and electronic Delphi round 2 surveys, respectively. Morphological definitions for 11 lesion types achieved the prespecified 70% consensus threshold, with 9 definitions reaching at least 90% agreement. After 2 electronic Delphi rounds, 16 of 18 guidance statements achieved the prespecified consensus threshold, with 13 statements receiving endorsement from more than 80% of participants. Two guidance statements related to assessment of tunneled plaques with multiple openings and assessment of scalp lesions failed to reach consensus. Conclusions and Relevance Common morphologic definitions and guidance that standardize assessment of HS lesions can be implemented in clinical trial protocols and investigator trainings with the goals of improving accuracy and reliability of investigator ratings.

Importance Despite treatment advances, metastatic recurrence continues to be a leading cause of morbidity and mortality. Empirical data on the incidence and survival after metastatic recurrence remain limited, as cancer registries historically do not collect data on recurrence. Objective To estimate the cumulative incidence (CMI) of metastatic recurrence among adolescents and young adults diagnosed with earlier-stage disease and compare survival to those with metastatic disease at diagnosis. Design, Setting, Participants This was a retrospective cohort study of adolescents and young adults aged 15 to 39 years who were diagnosed with nonmetastatic cancers from 2006 to 2018. Adolescents and young adults were identified from the California Cancer Registry linked with statewide hospitalization, emergency department, and ambulatory surgery encounters from the California Department of Health Care Access and Information. Data were analyzed from December 2023 to June 2025. Exposures Cancer types, including melanoma, sarcoma, and breast, cervical, colorectal, testicular, and thyroid cancers. Main Outcomes and Measures Metastatic recurrence was identified using International Classification of Diseases, Ninth Revision, Clinical Modification, and Tenth Revision, Clinical Modification, metastatic disease codes at least 6 months after cancer diagnosis or from an underlying cancer cause of death. Follow-up was through December 31, 2020. Results Of a total of 48 406 adolescents and young adults (median [IQR] age at diagnosis, 33.0 [28.0-37.0] years; 67.4% female), 9.2% had metastatic disease at diagnosis, and 9.5% had metastatic recurrence. Among 43 935 adolescents and young adults who presented with nonmetastatic disease, the 5-year CMI of metastatic recurrences was highest among patients with sarcoma (24.5%; 95% CI, 22.6%-26.6%) and colorectal cancer (21.8%; 95% CI, 20.3%-23.4%) and intermediate for cervical (16.3%; 95% CI, 15.0%-17.6%) and breast (14.7%; 95% CI, 14.0%-15.4%) cancers. The CMI for metastatic recurrence increased with increasing stage at diagnosis, with 5-year CMIs higher than 30% for all stage III cancers (except thyroid). The 5-year CMI of metastatic recurrence also increased over time for cervical cancer (2006-2009: 12.7% [95% CI, 10.8%-14.8%]; 2015-2018: 20.4% [95% CI, 17.5%-23.6%]) and decreased for colorectal cancer (2006-2009: 24.4% [95% CI, 21.3%-27.6%]; 2015-2018: 19.2% [95% CI, 16.4%-22.2%]). Survival after metastatic recurrence was worse than metastatic disease at diagnosis for all cancer types, except for testicular and thyroid cancers. Conclusions and Relevance The findings from this cohort study highlight the overall burden of metastatic disease in adolescents and young adults, expanding the knowledge of metastatic recurrences that help improve care for adolescent and young adult survivors throughout the cancer survivorship spectrum.

Importance Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have become substantially more popular as a medication to treat obesity and type 2 diabetes (T2D). Despite their known association with gastroesophageal reflux disease and vagal nerve stimulation, the association between GLP-1RAs and chronic cough has not been previously studied. Objective To assess the clinical association between GLP-1RAs and chronic cough. Design, Setting, and Participants This large, multicenter cohort study used clinical records from a US-based collection of electronic medical record data from April 28, 2005, to April 15, 2025, from 70 health care organizations. Adults (≥18 years) with T2D and prescription of a GLP-1RA were identified. Additionally, groups with T2D and prescription of another second-line diabetes medication, including dipeptidyl peptidase-4 (DPP-4) inhibitors, sodium-glucose cotransporter 2 (SGLT2) inhibitors, and sulfonylureas were created. After propensity score matching for various demographic and clinical characteristics, adjusted hazard ratios (aHRs) and 95% CIs were calculated using Cox regression analyses to estimate the risk of new chronic cough or gastroesophageal reflux disease diagnosis. Exposure GLP-1RAs or other second-line diabetes medication. Main Outcomes and Measures Chronic cough. Results Cohorts included 427 555 individuals (mean [SD] age, 55.8 [13.8] years; 251 928 female individuals [58.9%]) with T2D who were prescribed a GLP-1RA and 1 614 495 individuals (mean [SD] age, 63.7 [13.3] years; 712 946 female individuals [44.4%]) with T2D who were prescribed another second-line diabetes medication. After propensity score matching, individuals prescribed a GLP-1RA had significantly increased risk of new chronic cough compared with individuals prescribed any non–GLP-1RA second-line medication (aHR, 1.12; 95% CI, 1.08-1.16), DPP-4 inhibitor (aHR, 1.18; 95% CI, 1.11-1.26), or sulfonylurea (aHR, 1.32; 95% CI, 1.24-1.40) but not compared with SLGT2 inhibitors (aHR, 1.03; 95% CI, 0.98-1.09). After removing patients with a previous diagnosis of gastroesophageal reflux disease from analysis, patients prescribed GLP-1RAs had significantly increased risk of chronic cough compared with those prescribed any non–GLP-1RA (aHR, 1.29; 95% CI, 1.17-1.42), DPP4 inhibitor (aHR, 1.36; 95% CI, 1.17-1.58), SGLT2 inhibitor (aHR, 1.14; 95% CI, 1.02-1.28), or sulfonylurea (aHR, 1.25; 95% CI, 1.09-1.42). Conclusions and Relevance This cohort study suggests an association between GLP-1RA use and chronic cough. Further research is needed to confirm the existence, strength, and mechanisms of this association.

Goals: Describe the establishment and expansion of a global gastrointestinal (GI) partnership and its impact on the advancement of GI care in Rwanda. Background: GI disease disproportionately affects low- and middle-income countries. In Rwanda, governmental and nonprofit efforts have made significant progress in expanding access to health care in the wake of the 1994 genocide; however, specialized care remains largely unrecognized or inaccessible. In response, the Rwanda Ministry of Health established a partnership with an international gastroenterology NGO to address this critical need. Study: We present summative data generated by this partnership. To inform future global GI programs, we provide lessons learned and details about Rwanda’s successful establishment of an in-country, self-sustainable, and locally governed gastroenterology training program. Results: From 2017 to 2023, the partnership expanded the number of clinical sites receiving care from 4 to 11. Total procedural volume increased from 244 to 1069. Most common presenting upper GI symptoms included dyspepsia, reflux, and emesis, while most common lower GI symptoms included hematochezia and constipation. Since 2017, this partnership has increased the number of faculty volunteering in Rwanda (and Rwandan clinicians studying in US academic medical centers), expanded its geographical reach, assisted in the creation of a GI fellowship, and enabled Rwanda to become an East African hub for medical education. Conclusions: Lessons learned across ethical, financial, leadership, cultural, and medical domains from the successful establishment and expansion of an international GI partnership in Rwanda provides invaluable insights to guide development of future models of health care in emerging economies.
