PURPOSE To compare mortality risk among long-term survivors of high-grade serous ovarian cancer (HGSOC) with that of the general US population and to examine how mortality and recurrence trends have evolved under changing treatment approaches. MATERIALS AND METHODS This is a retrospective cohort study including patients with histologically confirmed HGSOC treated at a single referral cancer center from 1991 to 2022. Mortality risk, expressed as standardized mortality ratios (SMRs, ratio of observed deaths in the study population to expected deaths in an age-matched US population), was assessed at diagnosis and yearly on patients without events (disease persistence, recurrence, or death from any cause). RESULTS A total of 2,074 consecutive patients were included. The median follow-up was 12.5 years (IQR, 11.7-13.8). Most patients were stage III (1,396, 69.2%), 1,299 (62.8%) underwent primary cytoreductive surgery, and 1,688 (87.4%) received platinum-taxane as first-line therapy. At diagnosis, the mortality rate was 7.40 times higher than that in the general population (95% CI, 7.04 to 7.77). By 7 event-free years, the 95% CI for the SMR included 1 for the first time, and at 10 years, the SMR was 1.05 (95% CI, 0.72 to 1.49), indicating no statistically significant excess mortality compared with the general population. In those event-free at 10 years, the 5-year cumulative incidence of ovarian cancer–related deaths (8.2% [95% CI, 4.2 to 16.0]) was comparable with that of non–ovarian cancer–related deaths (6.3% [95% CI, 2.9 to 13.8]). CONCLUSION In this cohort, mortality risk steadily declined for patients who remained event-free, approaching that of the general population by 7 years after diagnosis. These results emphasize the importance of individualized, long-term follow-up to address both recurrence risk and survivorship needs.

ABSTRACT Evaluating patients following a COVID‐19 infection with multiple chronic, progressive symptoms can be challenging, but easy to navigate by using the temporal profile obtained from the clinical history, findings from the neurological exam, and screening for red flag symptoms.

Context.— The Goldman criteria are widely used to categorize diagnostic discrepancies in autopsy reports for hospital quality assurance. Despite their adoption, little is known about how consistently they are applied across institutions. Objective.— To evaluate the interrater reliability among academic pathologists applying the Goldman criteria to classify missed diagnoses in autopsy cases. Design.— Thirty autopsy cases from 2 academic hospitals were reviewed by 5 experienced autopsy pathologists. Each reviewer independently assigned Goldman classification scores (class I–IV) to missed diagnoses based on the original 1983 definitions. Consensus was defined as at least 60% agreement (≥3 of 5 raters). Fleiss κ and Gwet AC1 were calculated to assess interrater reliability. Results.— A total of 196 missed diagnoses were identified by at least 1 rater. Only 26% (51 of 196) achieved a consensus Goldman classification, and just 4% (8 of 196) had unanimous classification agreement. Most diagnoses (65%; 127 of 196) were not identified by at least 3 raters. Among consensus classification ratings, 49% (25 of 51) were class IV. Fleiss κ was 0.176 (slight agreement) while Gwet AC1 was 0.390 (fair agreement). Collapsing major (classes I–II) and minor (classes III–IV) categories modestly improved agreement. Conclusions.— Interrater agreement in applying the Goldman criteria is only fair to moderate, suggesting significant subjectivity in their application. As the criteria are used for institutional comparison and quality metrics, efforts to standardize definitions and provide reviewer training are warranted to improve reproducibility and utility.

ABSTRACT Background Infection enteritis is associated with the development of irritable bowel syndrome (IBS) and functional dyspepsia. Aim This study aimed to examine the long‐term risk of IBS and functional dyspepsia, and associated health care utilisation following infection enteritis. Methods We conducted a retrospective cohort study using TriNetX U.S. Network. Adults with infection enteritis were identified and matched to controls, balancing demographics and comorbidities. Primary outcomes were the risk of incident IBS and functional dyspepsia diagnoses at 1, 5, and 10 years. Secondary outcomes were rates of IBS‐ and functional dyspepsia‐related medications, endoscopy, abdominal imaging, and hospitalizations. Pathogen‐specific and multivariate analyses were performed to assess variations in IBS risk. Results After matching, 202,244 patients were identified in each study cohort. At 1 year of follow‐up, the infection enteritis cohort had higher rates of IBS (RR = 2.35; 95% CI: 2.14–2.59), functional dyspepsia (RR = 2.02; 95% CI: 1.84–2.22), use of IBS‐related medications (RR = 1.29; 95% CI: 1.26–1.31), functional dyspepsia‐related medications (RR = 1.56; 95% CI: 1.55–1.59), abdominal imaging (RR = 2.42; 95% CI: 2.29–2.54), and Oesophagogastroduodenoscopy/colonoscopy (RR = 1.57; 95% CI: 1.50–1.65). These risks remained significantly higher in the IE cohort at 5 and 10 years. Salmonella/Shigella (RR = 6.48), and Giardia lamblia (RR = 5.05) had the highest risk of developing incident IBS. Conclusion Infection enteritis was associated with increased risk of IBS and functional dyspepsia, rates of related medication use, and greater healthcare utilisation.

Abstract Background S0221 investigated weekly vs every 2 weeks dosing of doxorubicin (A) and cyclophosphamide (C) followed by paclitaxel in patients with high-risk early breast cancer. After an interim analysis, random assignment to the 2 AC arms was stopped for futility, and the trial was modified to study only the paclitaxel schedules. Methods Between December 2003 and November 2010, a total of 2716 patients were randomly assigned in a 2 × 2 factorial design to 15 weeks of weekly A and daily C vs 6 cycles of every 2 weeks AC; and weekly paclitaxel for 12 weeks vs 6 cycles of every 2 weeks paclitaxel. Between January 2011 and January 2012, an additional 578 patients were assigned to 4 cycles of every 2 weeks AC and randomly assigned to weekly vs every 2 weeks paclitaxel. Updated survival was assessed using log-rank tests and Cox regression models. We compared outcomes by breast cancer subtype as well. Results At a median follow-up of 12.1 years, there were no statistically significant differences among the 4 treatment arms in disease-free survival (DFS) (P = .91) or overall survival (P = .34) in the original protocol. Among the 578 patients assigned AC for 4 cycles and randomly assigned to paclitaxel weekly vs every 2 weeks paclitaxel, there were no overall differences in DFS (P = .32) or overall survival (P = .42). Conclusion As there were no statistically significant outcome differences in DFS or overall survival between the studied schedules of AC and paclitaxel with extended follow-up in the original or revised protocol, either paclitaxel schedule may be recommended, with selection based on toxicity, cost, or patient preference.

Background: Long COVID, the chronic sequela of SARS-CoV-2 infection, has affected millions of people worldwide. However, its pathogenesis and treatment remain unknown. To address this critical gap, the National Institutes of Health (NIH) developed the Researching COVID to Enhance Recovery (RECOVER) Initiative that included the Viral Persistence and Reactivation, and Immune Dysregulation (RECOVER-VITAL) study as one of the first of five NIH-sponsored, integrated platform protocols to support the rigorous and rapid investigation of potential interventions for Long COVID. Methods: Experts across academia, the NIH, and the community of patients and caregivers were brought together to design the RECOVER-VITAL protocol. We present the challenges and rationale underpinning critical components of this protocol and provide evidence for use of the platform for efficient execution of current and future Long COVID clinical trials. Facets of the RECOVER-VITAL protocol, including inclusion criteria, intervention groups, study procedures, investigation of biomarkers, and endpoints, were carefully crafted to advance the current and future science and operations of Long COVID clinical trials, particularly in the absence of existing data. The initial trial within the RECOVER-VITAL platform evaluated two durations of an antiviral drug, nirmatrelvir/ritonavir, to test the proposed etiology of viral persistence on the Long COVID symptom clusters of autonomic dysfunction, cognitive dysfunction, and exercise intolerance. The primary outcome measures were patient-reported, and secondary outcomes included performance-based measures for each of the symptom clusters of interest. Conclusions: The RECOVER-VITAL platform protocol has substantial implications for the design and conduct of future Long COVID clinical trials.

Objective: To evaluate the associations between surgeon-patient sex concordance, long-term clinical outcomes and healthcare costs. Background Data: Emerging data suggest surgeon-patient sex concordance may improve short-term outcomes, especially for female patients, yet its long-term effects remain unknown. Methods: We conducted a population-based retrospective cohort study of adults undergoing common surgeries in Ontario, Canada (2007-2019). Patients were followed for 90 and 365 days. Surgeon-patient sex concordance was categorized into four dyads. Multivariate generalized estimating equations clustered by procedure type evaluated composite and individual (complications, readmission, mortality) clinical outcomes and healthcare costs. Results: A total of 1,165,711 patients were included. Female patients treated by male surgeons, compared with female surgeons, were more likely to experience an adverse composite event (90 d: aOR 1.12, 95% CI 1.08–1.17, P <0.001; 365 d: aOR 1.09, 95% CI 1.05–1.14, P <0.001), with no association among male patients (90 d: aOR 1.00, 95% CI 0.94–1.05, P =0.89; 365 d: 0.99, 95% CI 0.92–1.07, P =0.87). Long-term total healthcare costs were greater for patients treated by male surgeons - an effect seen in both male patients (90 d: aRR 1.08, 95% CI 1.03-1.14, P =0.002 and 365 d: aRR 1.08, 95% CI 1.02-1.14, P =0.007) and female patients (90 d: aRR 1.10, 95% CI 1.05-1.14, P <0.001, 365 d: aRR 1.09, 95% CI 1.05-1.14, P <0.001). Conclusions: Surgeon-patient sex concordance was associated with improved long-term outcomes for female, but not male, patients, and female surgeons’ patients had lower healthcare costs. Given these benefits, further investigation into the mechanisms driving these outcomes is warranted.

Abstract Background The association between long-term use of benzodiazepines (BDZs) and cognitive function in patients with schizophrenia has not been fully characterized. This study aimed to investigate the relationship between long-term BDZs use and cognitive impairment in schizophrenia. Methods Data were derived from an observational study of treatment with atypical antipsychotics in Chinese patients with schizophrenia (SALT-C). Fifty-seven patients with long-term use of BDZs (≥ 60 days) were included, and 57 BDZs non-users were matched using propensity scores for age, sex, disease duration, and atypical antipsychotics received. Cognitive impairment was assessed using the Montreal Cognitive Assessment (MoCA); psychotic symptoms, illness severity, and psychosocial functioning were assessed with the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression-Severity (CGI-S) scale, and the Personal and Social Performance (PSP) scale. Between-group comparisons were performed using independent-samples t-tests or Mann–Whitney U tests. Multivariate analysis was performed using binary logistic regression. Results The long-term BDZs user group showed a significantly lower total MoCA score [16.02 (6.69)] than the BDZs non-user group [19.33 (7.11)] (P = 0.012). No significant between-group differences were observed in total scores on the PANSS, CGI-S, or PSP (all P > 0.05). Long-term BDZs use was independently associated with cognitive impairment (OR = 7.728, P = 0.017), whereas years of education was negatively associated with cognitive impairment (OR = 0.740, P = 0.007). Conclusions Long-term BDZs use is associated with poorer cognitive performance in patients with schizophrenia, suggesting that cognitive function should be monitored during BDZs treatment in this population.

OBJECTIVE Electrical stimulation mapping is a widely used technique to determine functional localization for medically refractory epilepsy. Sites where stimulation interferes with naming are often focal regions of the frontal and temporal cortex. The extent to which these crucial sites remain in the same location over time in an individual adult patient has not yet been established. The aim of this study was to determine whether cortical naming sites identified using stimulation mapping are stable in their anatomical location over time in adult patients with medically refractory epilepsy. METHODS Twenty-two patients who underwent electrical stimulation mapping for medically refractory epilepsy during surgical interventions separated by more than 1 year between 1967 and 2005 were included. A median of 8.35 years elapsed between mappings. The mean age at the first operation was 27.7 (range 10–39) years. Fourteen patients were female. Mapping occurred under two different conditions: intraoperatively in procedures conducted under local anesthesia or extraoperatively through implanted grid electrodes. A Bayesian hierarchical model of language site locations across repeated interventions was used to assess the stability of locations of stimulation-evoked interference in language naming. RESULTS Sites where electrical stimulation interferes with language naming were separated by a median of 0.6 cm between the 2 mappings. Eighty-six percent of the mapped sites related to language naming at the second operation were within 1.5 cm of a site identified at the first operation, 61% within 1 cm, and 36% within 0.5 cm. However, in 2 patients, none of the identified language naming sites at the second operation were within 1.5 cm of the sites from the first operation. CONCLUSIONS This unique, long-term series of neurosurgical mappings reveals that language naming sites in the cortex of adult patients with epilepsy show substantial long-term stability over many years. However, rare relocation of these sites does occur in some patients over many years.
