Abstract Objective In 2024, the US News and World Report (USNWR)'s Best Hospitals began reporting complications following elective outpatient otolaryngology procedures in its ears, nose, and throat (ENT) ranking. However, this methodology has not been clinically adjudicated in a peer‐reviewed domain. We aimed to conduct manual health record adjudication to assess whether the USNWR methodology accurately attributes complications following elective outpatient otolaryngology procedures. Study Design Case‐cohort. Setting A case‐cohort of n = 80 elective, outpatient otolaryngology procedure/complication pairings from January 2019 to October 2023 across four academic medical centers using the 2024 USNWR otolaryngology procedure subgroups and Solventum Ambulatory Potentially Preventable Complications (AM‐PPC) software. Methods We used the AM‐PPC‐defined complication types as our standard of comparison for our clinical adjudication. Using the electronic health record, we adjudicated: (1) Was there agreement (yes/no) on complication type between our clinical adjudication and the Solventum AM‐PPC software? (2) Was the complication clinically related to, or a sequela of, the index otolaryngology procedure (yes/no)? Results The clinical adjudication agreed on complication type in 59/80 (74%) of patients, and 63/80 (79%) were judged to be clinically related to the index otolaryngology procedure. In total, 50/80 (63%) complications were adjudicated to be in agreement on both the complication type and clinical relatedness to the index procedure, while 9/80 (11%) complications did not agree with the complication type nor were clinically related to the index procedure. Conclusion Outpatient complications reported in the USNWR ENT rating lack the specificity to exclude patients whose complications are sequelae of chronic underlying conditions or related to concurrent, non‐otolaryngology procedures.

Abstract Context Menstrual irregularities have been associated with cardiovascular disease (CVD) risk, but underlying etiologies may confer distinct risk profiles. Functional hypothalamic amenorrhea (FHA) has not been evaluated as a separate risk phenotype. Objective To assess the association between FHA phenotype and incident CVD and cardiometabolic risk factors. Design Prospective cohort study with biennial follow-up from 1993 to 2019. Setting Nurses’ Health Study II cohort. Participants The sample included 52,655 premenopausal women free of CVD in 1993. FHA phenotype was defined as irregular or absent cycles without PCOS traits combined with low body mass index and/or high physical activity. Intervention None Main Outcome Measures Incident CVD (coronary heart disease [CHD; myocardial infarction or coronary revascularization] and stroke) and incident elevated cholesterol, hypertension, and type 2 diabetes (T2DM). Results During up to 26 years of follow-up, 1,007 CVD events occurred. Among women who developed CVD, the median time to the first CVD event was 17.0 years (IQR, 11.3-21.0). FHA phenotype in mid-adulthood was associated with a 62% higher risk of CVD (95% confidence interval [CI]: 1.01–2.59), driven by an almost two-fold higher risk of CHD (hazard ratio [HR] = 1.91; 95% CI: 1.11–3.27), compared with women with regular cycles. FHA was also associated with T2DM (HR = 1.86; 95% CI: 1.41–2.47), but not hypertension or elevated cholesterol. Non-FHA menstrual irregularity was associated with elevated cholesterol, hypertension, and T2DM, but not CVD. FHA in early adulthood was not associated with outcomes. Conclusions FHA phenotype in mid-adulthood was associated with increased CHD risk independent of traditional risk factors. Menstrual history may serve as an early marker of cardiometabolic risk.

ABSTRACT Background Evaluating fairness in artificial intelligence (AI) is essential before clinical implementation to prevent unintended harm across diverse patient populations. This study assesses performance differences of an image-based surgical site infection (SSI) detection model across age, gender, geography, race, and skin color. Methods Model development/validation study using retrospective, multicenter data across surgical subspecialties from adults who submitted an image of their incision via the electronic health record within 30 days of their procedure between 2019-2024. Area under receiver operating curve (AUROC) was compared by age (<55 vs. ≥55 years old), gender (male vs. female), geography (Rochester, Minnesota vs. Jacksonville, Florida vs. Scottsdale, Arizona vs. regional Minnesota/Wisconsin areas), race (White/Caucasian vs. non-White/Caucasian), and skin color (Fitpatrick I-III vs. IV-VI and Monk A-E vs. F-J). Results Training data contained 13,702 images from 4,274 patients between 2019-2022 (50.1% ≥55 years old; 63.2% female; 91.6% White/Caucasian; 58.5% Rochester, 17.3% Florida, 10.5% Arizona; 96.3% light skin tone), of which 1,348 images (9.8%) had an SSI. No differences in SSI detection existed for age, gender, race, or skin color (AUROC 0.83-0.87, p>0.09), however geographical differences were significant: lowest AUROC 0.83 (95% CI 0.77-0.88) vs. highest AUROC 0.87 (95% CI 0.84-0.89, p=0.01). Temporal validation using 4,242 images from 1,353 patients between 2022-2023 showed intact fairness across subgroups (ΔAUROC ≤0.06) except geography (ΔAUROC ≤0.16). Conclusions The model behaved fairly across age, gender, race, and skin color, however geographical differences persisted. These findings have practical implications underscoring the importance of evaluating bias in clinical AI before deployment.

ABSTRACT Human intestinal diseases, including inflammatory bowel disease (IBD), are difficult to model because existing animal and in vitro systems do not capture the intestine’s integrated vascular, immune, and metabolic complexity. Here, we establish a custom normothermic machine perfusion platform that maintains surgically resected human intestinal tissue for up to 72 hours under near-physiological conditions. Discarded specimens from patients with nonmalignant intestinal diseases, including IBD and diverticulitis, were continuously perfused at 37°C with real-time hemodynamic and metabolic monitoring. Perfusion preserved tissue viability, mucosal architecture, epithelial integrity, oxygen consumption, metabolic activity, and vascular patency. Daily perfusate sampling enabled longitudinal profiling and experimental modulation of inflammatory mediators, revealing patient-specific immune states. This long-duration platform bridges reductionist in vitro models and clinical disease, enabling mechanistic studies of intestinal inflammation and future testing of personalized therapies in intact patient-derived tissue.

Background Menopause-related symptoms are common but undertreated. Digital tools that support symptom assessment and patient education may improve engagement. Objective To assess whether a previsit digital menopause symptom assessment and education tool increased treatment initiation and patient engagement compared to an educational pamphlet. Design Women aged 45–55 years with upcoming primary care appointments were invited to participate. Those with a total Menopause Rating Scale (MRS) score ≥5 indicating bothersome menopause symptoms were included. Participants were randomized to a digital menopause symptom assessment tool or a digital educational pamphlet and completed a post-visit survey (NCT06919887). Participants Of the 14,726 women invited to participate between May 12, 2025, and December 5, 2025, there were 653 (4.4%) enrolled that met eligibility criteria. Interventions Randomized to an mHealth app called emmii or a standard digital menopause educational pamphlet. Main measures Menopause treatment initiation within 30 days of the clinical visit was assessed by electronic health data. Baseline and post-visit surveys were collected assessing patient experience, engagement, and perceived usefulness. Rates of menopause hormone therapy (HT) prescribing were compared with a reference population of nonparticipants aged 45–55 who had a primary care appointment at Mayo Clinic during the same period and received no study education materials. Key results Of 653 participants enrolled and randomized, 383 completed both the baseline and post-surveys (171 intervention and 212 control). HT initiation among study participants was significantly higher than in the reference population of women (9.3% vs. 4.4%, p &lt; 0.001). There was no difference in HT initiation between the intervention (9.1%) and control groups (9.6%) ( p = 0.83). Initiation rates were 3.8% and 4.5%, respectively ( p = 0.64) for nonhormone therapies. Conclusions Among women with bothersome menopause symptoms, those who underwent previsit symptom screening and received educational materials had higher rates of HT initiation than women who did not participate in the study. These findings suggest that structured menopause education may improve recognition and management of menopause symptoms in routine clinical practice.

ABSTRACT The cohesin complex, composed of SMC1, SMC3, RAD21, and STAG1/STAG2, is essential for chromosome cohesion, DNA repair, and transcriptional regulation. Pathogenic variants in cohesin components cause cohesinopathies. The classical characteristics of cohesinopathies include developmental delay (DD), intellectual disability (ID), feeding difficulties, hypotonia, short stature, hearing loss, and dysmorphic features. Here, we present a 5‐year‐old boy with classical cohesinopathy features, including DD/ID and feeding difficulties, along with non‐classical features such as hypoglycemia, recurrent fever, and immunodeficiency. Trio exome sequencing identified a novel de novo missense variant of uncertain significance (NM_005862.3:c.643G>A(p.Val215Ile)) in the STAG1 gene. The variant localizes to the RAD21 interaction interface, and molecular dynamics (MD) simulations revealed conformational changes comparable to other STAG1 variants reported as likely pathogenic in patients, supporting a deleterious effect which may disrupt the STAG1‐RAD21 interaction interface. This case expands the phenotypic and molecular spectrum of STAG1‐related cohesinopathy and advances our understanding of the disease mechanism.
