Purpose Survivors of critical illness often acquire significant physical, cognitive, and psychological burdens following their intensive care unit (ICU) stay, termed “post-intensive care syndrome” (PICS). Screening for PICS is generally not performed outside of research settings largely due to lack of a simple assessment tool and time constraints. Methods This was a prospective cohort study at a single academic medical center in the USA. We included adults (18 years or older) who spent greater than 48 h in any ICU within the medical center. Following transfer out of the ICU and at 3 months, psychological, cognitive, and physical functioning were assessed using the Hospital Anxiety and Depression Scale, Impact of Event Scale-Revised, Montreal Cognitive Assessment-blind, and Barthel Index. We compared these validated questionnaires to a brief, 15-item PICS screening tool (5 questions/domain) that was developed by our multidisciplinary study team and administered to study participants after ICU discharge to general care. The primary objectives of this study were to assess the ability of validated screening tools administered at ICU discharge to predict PICS at 3 months and develop a novel screening tool for identifying patients at risk of PICS. Major Findings 191 participants completed the initial questionnaire, and 109 (56%) completed the 3-month follow-up. PICS tool scores were compared to 3-month follow-up data from validated questionnaires to evaluate predictive performance. Overall, the screening tool weakly-to-moderately correlated with continuous outcomes of the validated measures at 3-month follow-up. When evaluating sensitivity and specificity for individual domains, the screening tool had an area under curve of >0.7 for all three domains, indicating moderate-to-good sensitivity and specificity. Conclusions We developed a brief PICS screening tool that is feasible to use without prior training that modestly predicted the development of PICS following ICU stay.

Abstract Introduction and Objective This study aims to evaluate the learning curve and perioperative outcomes of single‐port extraperitoneal robotic radical prostatectomy (SP‐EP‐RARP) performed by a single surgeon at a high‐volume academic institution. Methods A retrospective review of a prospectively maintained database was conducted for patients who underwent SP‐EP‐RARP from September 2023 to August 2025. Key metrics included operative time, estimated blood loss, conversion rate, nerve‐sparing status, pathological margin status and continence (0–1 pad for safety), and 30‐day complication rate. Descriptive statistics were used, and outcomes were analysed chronologically to assess for trends suggesting a learning curve. Results The cohort included 53 patients who underwent extraperitoneal SP‐EP‐RARP. Median operative time was 213 min (IQR: 145–281). Median estimated blood loss was 100 mL (IQR: 75–125). Nerve‐sparing was attempted in 75.5% of cases. No assist or plus one ports were utilized. Final pathology revealed pT2 disease in 64.1% (34 cases), pT3a in 32.1% (17 cases) and pT3b in 3.7% (2 cases). Overall positive margin rate was 26.4%. Thirty‐day Clavien–Dindo Grades I–II complication rates were 11.3%, and no major complications or 90‐day complications were reported. Continence rates at 6 weeks, 3 months and 6 months were 72%, 72% and 75%, respectively. Stabilization of operative times and intraoperative outcomes occurred after approximately 25–30 cases. Conclusion SP‐EP‐RARP can be safely implemented by a newly graduated fellowship‐trained robotic surgeon with acceptable oncologic and functional outcomes. Initial learning can be estimated at approximately 25–30 cases.

Background Suicidal behaviour shows notable sex differences, and understanding whether genetic factors contribute to these differences is critical for identifying at-risk individuals and prevention. Objective We aim to investigate the genetic contribution to suicide attempts and examine whether genetics account for sex differences in incidence. Methods This population-based cohort study includes 3.1 million individuals born 1963–1998 and followed through Swedish National Registers, including hospitals and specialist outpatient diagnoses and cause of death data. Suicide attempts were identified using ICD codes, indicating intentional self-harm, self-harm using lethal methods or leading to hospitalisation, or resulting in death. Familial aggregation, coaggregation, pedigree heritability and genetic correlations were estimated using genealogical data. For sex-specific analyses, we examined mother–daughter, female sibling, father–son and male sibling pairs, separately. Findings Suicide attempts were more common among females than males (3.3% vs 2.6%). In both sexes, risk aggregated within families (ORs ranged 1.6–3.4 across relative types) and was higher in first-degree than second-degree relatives. Familial aggregation was stronger in females than in males, and in same-sex first degree relatives compared with cross-sex pairs. Pedigree heritability was 41.9% (95% CI 36.0 to 48.4%) and did not differ significantly by sex (female 51.4% (95% CI 40.1% to 58.6%), male 45.1% (95% CI 32.3% to 52.5%), Bootstrap p value 0.40). Suicide attempt showed moderate to high pedigree genetic correlations with psychiatric disorders, strongest with substance use disorders (SUD, r g =0.85 (95% CI 0.83 to 0.96)), with no significant sex differences. The genetic correlation between female and male suicide attempts was high (0.85 (95% CI 0.80 to 0.99)), suggesting a substantial genetic overlap. Conclusions Suicide attempt has a moderate heritable component that largely overlaps between females and males and with other psychiatric disorders, particularly SUD. Stronger familial aggregation in females and in same-sex pairs highlights the potential role of sex-specific environmental or social factors. Future research should focus on non-genetic contributors and their potential interaction with genetic factors to better understand and address sex disparities in suicidal behaviour Clinical implications Genetic risk for suicide attempt is substantial but does not fully explain sex differences in incidence. Clinicians should, therefore, consider non-genetic, including sex-specific environmental and social factors, alongside family history and psychiatric comorbidity when assessing suicidal risk.

Background: Metastatic squamous cell carcinoma of the anus (SCCA) carries a poor prognosis, with systemic therapy remaining the standard of care. While metastasis-directed therapy improves outcomes in select gastrointestinal malignancies, the role of liver-directed intervention in metastatic SCCA remains undefined. We evaluated clinicopathologic features and oncologic outcomes of patients with liver-limited metastatic SCCA treated with curative-intent hepatic local therapy at a tertiary academic center. Methods: We conducted a retrospective cohort study of adults with histologically confirmed SCCA and liver-only metastatic disease who underwent curative-intent hepatic resection or ablation at Mayo Clinic between 1993 and 2023. Patients with extrahepatic disease or incomplete records were excluded. Demographic, tumor, treatment, and outcomes data were abstracted from electronic medical records. Overall survival (OS) and disease-free survival (DFS) were estimated using the Kaplan–Meier method. Prognostic factors were assessed using univariate Cox proportional hazards models. Results: Twenty-five patients met inclusion criteria. Median age was 56.7 years, and 92% were female. Most patients had metachronous metastases (76%), a single hepatic lesion (56%), and unilobar disease (76%). Pre-intervention systemic therapy was administered in 52% of patients, with radiographic complete or partial responses observed in all treated patients. Liver-directed therapy consisted of surgical resection in 80% and thermal ablation in 20%. Among surgical patients, 90% achieved microscopically negative margins. With a median follow-up of 22 months, disease recurrence occurred in 80% of patients, most commonly within the liver. Median DFS was 7.27 months. Median OS from the date of liver-directed therapy was 51.3 months. On univariate analysis, poorly differentiated tumor histology was associated with inferior OS (hazard ratio 4.67, p = 0.018). No other clinicopathologic variables were significantly associated with DFS or OS. Conclusions: In this single-institution experience, carefully selected patients with liver-limited metastatic SCCA undergoing curative-intent hepatic-directed therapy achieved prolonged overall survival, substantially exceeding historical outcomes with systemic therapy alone. Despite frequent recurrence, the observed median OS exceeding four years supports consideration of liver-directed therapy within a multidisciplinary framework for patients demonstrating favorable disease biology and response to systemic treatment. Prospective studies are needed to better define patient selection and optimal integration of local and systemic therapies in the modern treatment era.

Objective: To survey critical areas of variation in published research methodology with a primary aim of highlighting fundamental aspects that contribute to ongoing controversy surrounding optimal management of patients with sporadic vestibular schwannoma. Interventions: Observation, stereotactic radiosurgery (SRS), and microsurgery. Main outcome measures: Variation in reported outcomes surrounding facial function, useful hearing, tumor pseudoprogression following SRS, and tumor growth/natural history. Results: Published research defines “good” post-treatment facial function as anything ranging from HB I, ≤HB II, to ≤HB III. While most studies define serviceable hearing as AAO Class A/B, others include Class C in published post-treatment hearing preservation results; meanwhile, patients report their greatest decrement in quality-of-life at a threshold around 75% in word recognition scores. Heterogeneously defined as post-SRS tumor growth 6 months after SRS to 5 years after SRS, the reported incidence of tumor pseudoprogression ranges from 7% to 77% within the published literature. Natural history studies that employ linear tumor measurements consistently suggest most tumors do not grow following diagnosis, whereas volumetric studies of natural history suggest the exact opposite is true. Limited follow-up and absent time-to-event analyses undermine many outcomes surrounding vestibular schwannoma that are inherently time-dependent. Conclusions: Disparate definitions used in vestibular schwannoma research beget variable outcome reporting and confuse interpretation of optimal management, particularly for the increasingly common scenario of a small tumor in a minimally symptomatic patient. Progress towards optimizing management requires re-evaluation and alignment on key outcome measures to improve consistency in reporting with renewed emphasis on clinically significant, patient-driven outcomes that often exceed the thresholds most frequently studied to date.

ABSTRACT 162 patients with relapsed secondary central nervous system lymphoma (R‐SCNSL) (median age, 65 years; male, 59.9%) including central nervous system (CNS)‐only ( n = 120) and concomitant CNS/systemic relapse ( n = 42) were retrospectively analyzed. Overall, 21.9% of patients were classified as high risk according to the CNS International Prognostic Index (CNS‐IPI). Several biological and clinical features were significantly associated with leptomeningeal involvement, including double‐ or triple‐hit (DHL/THL) status, MYC rearrangement, negative BCL6 expression by IHC, bone marrow involvement, and concomitant R‐SCNSL. Multivariable analysis showed that leptomeningeal involvement independently predicted inferior OS and was associated with a 98% increase in the hazard of death compared with parenchymal relapse (HR = 1.98, 95% CI: 1.20–3.26, p = 0.008). Based on anatomical localization, R‐SCNSL was classified into four subtypes: parenchymal‐only involvement (parenchymal‐CNS [P‐CNS], 68/42%) and parenchymal involvement plus systemic relapse (parenchymal‐concomitant [P‐concomitant], 17/10.5%); and leptomeningeal with or without parenchymal involvement (leptomeningeal‐CNS [LM‐CNS], 52/32.1%) and leptomeningeal with systemic relapse (leptomeningeal‐concomitant [LM‐concomitant], 25/15.4%). This anatomical classification significantly impacted OS and PFS ( p < 0.001). Two‐year OS and PFS were 58.2% and 29.1% for P‐CNS, 32.4% and 17.7% for P‐concomitant, 22% and 13.9% for LM‐CNS, and 7.1% and 0% for LM‐concomitant, respectively. ASCT showed a trend toward improved survival among patients with a response (CR/PR) in a 4‐month landmark analysis. These findings support the clinical application of the anatomical classification in the management of R‐SCNSL.

ABSTRACT Background Sunlight has profound impacts on physical and mental health, beyond vision, including effects on circadian rhythms, alertness, mood, and sleep. A family history of any mood disorders is strongly associated with psychiatric disorders including bipolar disorder. The purpose of this study was to evaluate the association between a family history of any mood disorder in patients with bipolar I disorder and solar insolation at varied international onset locations. Methods Data for this analysis were available from 5842 patients with a diagnosis of bipolar I disorder obtained at 83 collection sites in both hemispheres. This included 4752 patients from 71 collection sites in the northern hemisphere and 1090 patients from 12 collection sites in the southern hemisphere. Patient data variables were obtained from records or interviews. Solar insolation data were obtained from The National Aeronautics and Space Administration (NASA) Power database for each onset location, and the ratio of the mean monthly minimum/mean monthly maximum solar insolation was calculated. Typically, the ratio is largest near the equator (little yearly change in solar insolation) and smallest near the poles (large yearly change in solar insolation). Results A significant relationship was found between a family history of any mood disorder, the ratio of the mean monthly minimum/mean monthly maximum solar insolation, and gender. The odds of a family history of mood disorder increased as patient location nears the poles and decreased near the equator. Female gender also increased the odds of having a family history of a mood disorder. Conclusions This study highlighted the association between family history, solar insolation, and gender in international patients with bipolar I disorder. Given the profound effects of sunlight on human health, the family of patients with bipolar disorder who live in the same location with the same solar insolation, and especially females, may be at increased risk for a mood disorder.

ABSTRACT The COVID‐19 pandemic underscored the critical need to strengthen healthcare systems and optimize resource allocation planning during times of disruption and crisis. This retrospective, single‐center, cross‐sectional study included 33,158 admissions for patients ≤ 17 years old admitted to the Children's Hospital (CH) between January 1, 2017, and December 31, 2021. Data was abstracted using Vizient Clinical Data Base and the internal data warehouse. A Poisson regression model was implemented to compare admission diagnosis patterns during the pre‐ and intra‐pandemic phases. CH SARS‐CoV‐2 prevalence rate was 0.1% in 2020 and 0.5% in 2021. There was a decrease in overall admissions to the CH ( p < 0.01) and PICU ( p < 0.01) at the onset of the pandemic. There were significant and variable differences in admission patterns for certain infectious and seizure‐related diagnoses. The CH experienced an increase in certain specific mental health diagnoses. Seasonality was noted for viral bronchiolitis during the pre‐pandemic phase, but was disrupted during the intra‐pandemic phase. The COVID‐19 pandemic had a significant impact on the number and pattern of admissions, despite low prevalence of SARS‐CoV‐2 in our hospital. These changes may be secondary to COVID‐19 community mitigation strategies. Results can inform anticipated patterns during future pandemics.

Abstract Objectives Traditional laboratory regulatory frameworks provide robust guidance for conventional clinical testing but lack requirements for data documentation for artificial intelligence and machine learning (AI/ML) solutions. This gap creates significant risks since AI solutions directly inherit patterns, biases, and limitations from their training data. Here, we describe the development and implementation of a comprehensive data documentation checklist with accompanying data lineage for use within an AI lifecycle framework for clinical laboratories. Methods Building on the previously established Clinical AI Readiness Evaluator (CARE) framework, we developed a comprehensive data checklist and data lineage methodology through a multiphase process, including (1) comprehensive review of existing AI/ML data documentation frameworks, (2) focused meetings with 3 institutional AI operations teams, and (3) 3 rounds of iterative refinement by our multidisciplinary team. The checklist’s effectiveness was then assessed using 3 diverse AI/ML projects moving through the CARE framework. Results The CARE Data Checklist and Data Lineage provide a structured approach to documenting critical aspects of datasets used in AI/ML projects, including data composition, demographics, collection methods, labeling processes, usage constraints, maintenance requirements, and a data readiness assessment. The checklist addresses unique data-centric challenges of AI/ML applications, facilitating transparency, reproducibility, and regulatory compliance. Conclusions The CARE Data Checklist and Data Lineage serve as both a technical guide and a communication tool bridging gaps between technical and clinical stakeholders. By working on these documents early in the AI lifecycle, laboratories can anticipate and address data-related challenges, ultimately saving time, optimizing resources, and improving the reliability of AI-augmented laboratory solutions.

Abstract Rare Mendelian disorders affect 300-400 million people globally. Although genetic testing has become widely adopted, gene-specific evidence for tailored variant interpretation remains scattered across resources. We present Gene Portals, a framework for gene-centered multimodal knowledge bases that co-localize expert-harmonized clinical data, functional assays, population variation, structural annotations and gene-specific ACMG/AMP specifications within a single resource. A modular interface integrates this unified evidence with VCEP-refined ACMG specifications to enable automated gene-specific variant classification, infer molecular mechanisms, and support cross-gene analyses. We demonstrate the framework’s utility across five Gene portals spanning eleven neurodevelopmental disorder-associated genes, integrating data from 4,423 individuals with 2,838 unique variants, 36,149 ClinVar submissions, and 1,044 expert-curated molecular readouts. By organizing evidence that is otherwise dispersed across multiple sources into a unified, queryable framework, the SCN, GRIN, CACNA1A, SATB2 and SLC6A1 Gene Portals became widely used community resources and provide an extensible template for standardized rare-disease variant interpretation and mechanism-aware discovery.
