Abstract Background The associations between bilateral oophorectomy or hysterectomy with ovarian conservation and the risk of Parkinson's disease (PD) remain inconclusive. Objectives To evaluate the evidence on these two associations. Methods We conducted a systematic search across Embase, PubMed, Scopus, MEDLINE, and Web of Science through May 15, 2024. Data were extracted independently by two reviewers, and random‐effects meta‐analyses were performed. Results Eight studies with a total of 242,275 women were included. For bilateral oophorectomy, the effect size (ES) was greater than 1.0 in 5 of 8 studies. The pooled analysis showed a significant association between premenopausal bilateral oophorectomy and an increased risk of PD in cohort studies (hazard ratio [HR] 1.32; 95% CI 1.12–1.56) but not in case–control studies or combining both cohort and case–control studies. There was a suggestive trend of increasing risk with younger age at bilateral oophorectomy. For hysterectomy with ovarian conservation, the ES was greater than 1.0 in all six studies. The pooled analysis showed a non‐significant association in cohort studies and in case–control studies; however, the association was significant when combining both cohort studies and case–control studies (ES 1.19; 95% CI 1.01–1.41). Conclusions Current studies provided low to moderate evidence for the associations between bilateral oophorectomy and hysterectomy with ovarian conservation and increased risk of PD. However, the evidence was only observational and there was important heterogeneity across the case–control studies. Future studies should focus on surgeries performed at younger ages and on the possible effects of estrogen replacement therapy.

Abstract Objective To compare the long‐term risk of subsequent abdominopelvic surgery in women who underwent hysterectomy with ovarian conservation (H‐OC) versus referent women, and in women who underwent abdominal H‐OC versus vaginal H‐OC. Methods We conducted a population‐based cohort study in Olmsted County, Minnesota, USA including 1573 women who underwent H‐OC for a benign indication at age 18–44 years between January 1, 1980, and December 31, 2002, and 1573 age‐matched (±1 year) referent women who had not undergone hysterectomy or any oophorectomy as of the matching date. For both the H‐OC women and the referent women, we defined the index date as the H‐OC or matching date plus 6 months. The index date served as the starting point for follow‐up. Results Overall, we found an increased risk of subsequent lysis of adhesions in women who underwent H‐OC compared to referent women (hazard ratio [HR], 1.57 [95% confidence interval [CI]: 1.09–2.27]). Women undergoing H‐OC also had an increased risk of subsequent gastrointestinal tract procedures (HR, 1.18 [95% CI: 1.05–1.31]) compared to referent women. When comparing surgical route of H‐OC, we identified an increased risk of subsequent adnexal surgeries in women undergoing abdominal compared with vaginal H‐OC (HR, 1.91 [95% CI: 1.40–2.61]). Conclusion Women who underwent H‐OC have an increased risk of subsequent abdominopelvic surgeries compared to referent women. In addition, women who underwent abdominal H‐OC have an increased risk of subsequent adnexal procedures compared to women who underwent vaginal H‐OC.

Objectives: To determine the risk of developing de novo carpal tunnel syndrome (CTS), arthritis, or rheumatoid arthritis in women who underwent hysterectomy with bilateral ovarian conservation (H-OC) before reaching spontaneous menopause. Methods: We identified 1,573 women undergoing H-OC for a benign indication at age 18 to 44 years between 1980 and 2002 in Olmsted County, Minnesota. Each woman was age-matched (±1 y) to a referent woman who had not undergone hysterectomy or oophorectomy before the matching date (index date). Diagnostic codes for CTS and arthritis were extracted from the Rochester Epidemiology Project medical records-linkage system through 2019. Hazard ratios (HRs) and 95% CIs were estimated using Cox proportional hazards models and the two cohorts were balanced for 19 chronic conditions and for several potential confounders present at index date. Results: Over a median 25.8-year follow-up, women undergoing H-OC had an increased risk of developing CTS (HR: 1.33; 95% CI: 1.13-1.56) compared with referent women. The risk was similar in strata by age at H-OC and was higher for women with endometriosis and menstrual disorders indications. Women undergoing H-OC also had an increased risk of developing arthritis (HR: 1.34; 95% CI: 1.23-1.47). The risk was similar in strata by age at H-OC and by indication. Rheumatoid arthritis considered separately was also associated with H-OC (HR: 1.55; 95% CI: 1.05-2.30). Conclusions: H-OC was associated with an increased risk of de novo CTS, arthritis (all types), and rheumatoid arthritis. Further studies are needed to confirm these associations and to explore potential biological mechanisms.

Objective To study the reliability and validity of adverse childhood experiences (ACE) scores measured using a questionnaire versus abstraction of medical records, and to test whether the scores vary by history of bilateral oophorectomy, or by age and presence of anxiety or depressive symptoms at the time of questionnaire administration. Design The study involved a reliability component and a predictive validity component. Setting A population-based sample in Olmsted County, Minnesota, was derived from the Mayo Clinic Cohort Study of Oophorectomy and Aging-2. Participants We included 198 women who underwent premenopausal bilateral oophorectomy for a non-malignant indication between 1988 and 2007 and 174 referent women of the same age randomly sampled from the general population (total of 372 women). At a later time (median of 22.7 years later), the women were contacted and invited to self-administer the ACE questionnaire during an inperson visit. Independent of the visit, their medical records were abstracted for ACE by a physician. Interventions Questionnaire and abstraction-based ACE scores. Main outcome measures Agreement between the two ACE scores (reliability; weighted kappa statistics) and comparison of incidence of multimorbidity in women with ACE scores ≥1 vs 0 (predictive validity; survival analyses). Data were analysed in March and April 2024. Results The 372 women in the study had a median age of 65 years at the time of ACE questionnaire self-administration (IQR, 62–69). Questionnaire-based ACE scores showed moderate agreement with abstracted ACE scores (weighted kappa 0.44 (95% CI 0.34 to 0.54)). The cut-off score of ACE ≥1 showed an overall fair agreement between the two scores (kappa 0.33 (95% CI 0.24 to 0.43)). A comparison of the cumulative incidence of multimorbidity in women with an ACE score ≥1 versus women with ACE score of 0 yielded a HR of 1.13 (95% CI 1.00 to 1.27) for abstracted ACE and 1.13 (95% CI 1.01 to 1.27) for questionnaire-based ACE. The best predictive validity was for ACE measured by both methods combined (either or) with a HR of 1.29 (95% CI 1.13 to 1.46). Conclusions and relevance Questionnaire-based ACE scores have moderate agreement with medical records abstracted ACE scores. However, both sets of ACE scores are predictive of the accumulation of multimorbidity at older age and should be considered complementary.

Abstract Objectives We aimed to assess the expression of biomarkers of response to antibody-drug conjugates (TROP2 and nectin-4) and immune microenvironment (NKG7, PD-L1, and B7-H3) in penile squamous cell carcinoma (pSCC). Methods Our archive was queried for patients who had a penectomy for pSCC between 2000 and 2022. Primary tumors were immunostained for B7-H3 and NKG7, while metastatic specimens were immunostained for TROP2 and nectin-4. Expression of PD-L1, TROP2, and nectin-4 in primary tumors was previously characterized. H-scores (0-300) were used to quantify expression. Associations between biomarkers, tumor-infiltrating lymphocytes (TILs), and clinicopathologic and outcome parameters were evaluated. Results For both TROP2 and nectin-4, H-scores within the lymph node metastases were higher compared to those within the primary tumors (mean, 264.5 vs 244.8, P = .0003; mean, 170.6 vs 146.7, P = .05, respectively; 33 paired specimens). For B7-H3 (n = 107), 32.7% of the primary tumors had an H-score of more than 0. In 34.8% of the cases, NKG7 expression was observed in 25% to 50% of the TILs. A significant association was noted between TIL density, B7-H3, NKG7, and PD-L1 expression. Conclusions Therapeutic strategies targeting TROP2 and nectin-4 hold promise for patients with advanced pSCC. The potential of PD-L1, B7-H3, and NKG7 for predicting response to immunomodulatory treatment warrants further research.

Abstract The impact of early-life traumatic experiences on late-life morbidity remains partly unknown. We tested the hypothesis that adverse childhood experiences (ACE) and specifically abuse (physical, verbal or emotional, or sexual) experienced during childhood or early adulthood are associated with a higher rate of accumulation of multi-morbidity in women. Here we show strong evidence in support of the hypothesis. We studied 1,026 women aged 21–45 years randomly selected from the general population in Olmsted County, Minnesota and used the Rochester Epidemiology Project medical records-linkage system to measure the rate of development of 18 chronic conditions. The women had a median age of 41 years at inclusion in the study and were followed historically for a median of 21 years. Women with an ACE score ≥ 2 had higher incidence of 10 of the 18 chronic conditions considered separately and an accelerated accumulation of multi-morbidity measured as a score compared to women with ACE score 0. In addition, women exposed specifically to abuse in childhood or early adulthood had accelerated accumulation of multi-morbidity. We excluded the possible confounding effect of socioeconomic status and explored a series of possible mediation events or characteristics. We discuss several possible biological and social or behavioral mechanisms underlying these associations.

Abstract Background A dual filtration-based method for determination of serum labile bound copper (LBC) and LBC fraction (LBC/total copper) was developed. Reduced total copper, elevated LBC, and elevated LBC fraction have been reported in Wilson disease (WD). Methods To evaluate the diagnostic performance of these markers, samples were obtained from 21 WD treatment-naïve (WD-TN, no WD treatment or <28 days of treatment) patients, 46 WD standard-of-care–treated (WD-SOC) patients, along with 246 patients representing other potential disorders of copper status. These were then compared to 213 reference interval population patients. Results Receiver operating characteristic curves for the reference population vs WD-TN yielded areas under the curve for total copper, LBC, and LBC fraction, of 0.99, 0.81, and 0.98, respectively. Using Youden cutoffs, sensitivity/specificity for WD-TN was 95%/97% for total copper, 71%/85% for LBC, and 95%/94% for LBC fraction. LBC values, but not total copper and LBC fraction, differed substantially between WD-TN and WD-SOC cohorts. We propose a dual model wherein total copper and LBC fraction results must agree to be classified as a “positive” or “negative” result for WD. This correctly classified 19/21 WD-TN patients as positive, and 194/213 reference interval patients as negative. The remaining “indeterminate” patients (representing approximately 9% of the reference and the WD-TN populations) exhibited conflicting total copper and LBC fraction results. When indeterminate results are excluded, this model exhibited apparent 100% sensitivity/specificity. Conclusions Agreement of total serum copper and LBC fraction classification may constitute an effective “rule-in” and “rule-out” assessment for WD-TN patients.
