Menopause is a normative midlife transition characterized by profound endocrine remodeling and a high burden of symptoms and functional change. Accumulating epidemiologic and translational evidence links menopausal transition with shifts in cardiometabolic risk, musculoskeletal health, sleep, mood, and perceived cognitive function. However, most data support association rather than definitive causal acceleration of aging independent of chronological time. This narrative review proposes a menopause-centered healthspan framework that integrates biological, neurocognitive, and psychosocial domains and translates evidence into pragmatic clinical pathway tools. To inform topic selection and prioritize higher-level evidence, including guidelines, randomized trials, meta-analyses, and large cohort studies, a structured evidence scan utilizing PubMed and targeted citation tracking was performed. The evidence scan identified 256 citations. After duplicate removal, titles/abstracts of 162 unique records were reviewed, of which 102 citations informed the final narrative synthesis. The results emphasize that menopausal hormone therapy remains the most effective treatment for vasomotor symptoms and an evidence-based option for reducing fracture risk in appropriate candidates. However, it is not indicated for the primary prevention of cardiovascular disease or dementia. Absolute risks and benefits vary by age, time since menopause, and formulation/route. The neurocognitive section distinguishes common, often transient midlife cognitive complaints from long-term neurodegenerative outcomes, highlighting that menopause is not established as an independent dementia risk factor in the general population. Overall, the framework aims to support individualized, equity-informed care during menopausal transition.

Background: The aim of this study was to examine various patient factors affecting first programmed embryo transfer (ET) outcomes under the freeze-all policy at a single tertiary university infertility center. Methods: This retrospective observational study reviewed the medical records of 243 couples who underwent their first ET using blastocysts collected under the freeze-all antagonist-controlled ovarian stimulation (COS) protocol from 2015 to 2023. Patients were grouped into pregnant and nonpregnant groups, and their data, including demographics, COS and ET outcomes, and embryo storage duration, were analyzed. Results: Patient body mass index, cause of infertility, follicle-to-oocyte index, distribution of blastocyst grades, number of transferred embryos, and embryo storage duration were not significantly different between the groups. In a simple comparative analysis, patients with successful clinical pregnancy tended to have significantly lower female and male age (33.83±3.67 and 35.32±4.54 years vs. 37.07±4.15 and 39.33±5.60 years, respectively), higher anti-Müllerian hormone levels (6.27±5.32 ng/mL vs. 4.14±3.82 ng/mL) and antral follicle counts (14.20±8.26 vs. 10.04±5.75), and higher numbers of retrieved oocytes and metaphase II oocytes (13.74±6.92 and 9.64±6.19 vs. 11.21±6.04 and 7.53±5.56, respectively). Multivariate logistic regression analysis of these variables revealed that only male age was a significant factor for successful clinical pregnancy (odds ratio, 4.768; 95% confidence interval, 1.252–18.162; p=0.022). Conclusion During the first programmed ET using blastocysts collected under the freeze-all antagonist COS protocol, male age and correspondingly the quality of gametes for fertilization were crucial for successful pregnancy, having more importance than calculated female ovarian reserve and embryo storage duration.

Purpose: To evaluate whether extended pelvic lymph node dissection (PLND) improves survival outcomes compared with standard PLND in patients with bladder cancer (BCa) undergoing radical cystectomy (RC), and to assess its potential benefits in patients with prior or concurrent radical nephroureterectomy (p/cRNU). Materials and Methods: A multicenter analysis included 2202 patients with BCa undergoing RC with standard or extended PLND at 11 tertiary centers from 2003 to 2023. Following propensity score matching, 659 pairs (n=1,318), including 128 patients with p/cRNU, were analyzed. Recurrence-free survival (RFS) was the primary outcome, while overall survival (OS), cancer-specific survival (CSS), and readmission rates were secondary outcomes. Survival analyses performed using Kaplan-Meier methods and clustered Cox models. Results: Extended PLND yielded significantly more lymph nodes than standard PLND (median: 27.0 vs. 17.0, p<0.001) but did not improve RFS, CSS, or OS in the overall cohort (all p>0.05). Extended PLND increased readmission rates (28.4% vs. 20.2%, p=0.001) and readmission risk (odds ratio, 1.57; 95% confidence interval [CI], 1.15–2.16, p=0.005). However, subgroup analysis revealed extended PLND significantly improved RFS in patients with p/cRNU (hazard ratio, 0.54; 95% CI, 0.38–0.77; p<0.001). Conclusion Extended PLND does not provide survival benefits for overall patient population and increases readmission risk but significantly improves RFS in patients with p/cRNU. Tailoring PLND extent based on upper tract disease status is recommended.

Objectives: This study was conducted to compare the clinical and hormonal characteristics among women with polycystic ovary syndrome (PCOS) phenotype D, functional hypothalamic amenorrhea (FHA) with polycystic ovarian morphology (PCOM), and FHA without PCOM and investigate potential markers for their distinction. Methods: This retrospective pilot study included women who were examined for menstrual irregularities at a Korean tertiary hospital during 2018–2025 with following conditions: PCOS-D (n = 66), FHA with PCOM (n = 10), and FHA without PCOM (n = 29). Clinical features and hormonal profiles were analyzed using nonparametric tests, effect size estimation, and logistic regression. Results: BMI, along with LH, FSH, and AMH levels differed significantly across groups. AMH levels exhibited the following gradient:highest in PCOS, intermediate in FHA-PCOM, and lowest in FHA without PCOM. Subgroup analysis indicated that LH and FSH levels alongside LH/FSH ratio distinguished PCOS-D from FHA-PCOM (all P < 0.001, large effect sizes). Logistic regression revealed LH/FSH ratio as the only independent predictor (OR 58.88, 95% CI 3.29–1054.27). FHA without PCOM exhibited more persistent amenorrhea, whereas FHA-PCOM appeared milder and possibly reversible. Conclusions LH/FSH ratio, supported by BMI and clinical history, may help distinguish PCOS-D from FHA-PCOM. FHA-PCOM represents a distinct but understudied subgroup. These results are preliminary and require validation through larger prospective studies.

Background and Objectives: Kawasaki disease (KD) is an acute vasculitis that primarily affects children under age 5 years. Approximately 20–25% of untreated children with KD and 3–5% of those treated with intravenous immunoglobulin therapy develop coronary artery aneurysms (CAAs). The prevalence of CAAs is much higher in male than in female patients with KD, but the underlying factors contributing to susceptibility to CAAs in patients with KD remain unclear. This study aimed to identify sex-specific susceptibility loci associated with CAAs in KD patients. Methods: A sex-stratified genome-wide association study (GWAS) was performed using previously obtained GWAS data from 296 KD patients and a new replication study in an independent set of 976 KD patients by comparing KD patients without CAA (controls) and KD patients with aneurysms (internal diameter ≥5 mm) (cases). Results: Six male-specific susceptibility loci, PDE1C, NOS3, DLG2, CPNE8, FUNDC1, and GABRQ (odds ratios [ORs], 2.25–9.98; p=0.00204–1.96×10−6 ), and 2 female-specific susceptibility loci, SMAD3 (OR, 4.59; p=0.00016) and IL1RAPL1 (OR, 4.35; p=0.00026), were significantly associated with CAAs in patients with KD. In addition, the numbers of CAA risk alleles additively contributed to the development of CAAs in patients with KD. Conclusions A sex-stratified GWAS identified 6 male-specific (PDE1C, NOS3, DLG2, CPNE8, FUNDC1, and GABRQ) and 2 female-specific (SMAD3 and IL1RAPL1) CAA susceptibility loci in patients with KD.

Background: This study aimed to investigate the obstetric and perinatal outcomes of singleton deliveries following frozen embryo transfer (FET) cycles using different endometrial preparation methods. Methods: We analyzed data on 44,118 singleton pregnant women who underwent in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI), resulting in delivery or abortion, from the South Korean National Health Insurance Service database. Stratification was based on the type of embryo transfer, viz. fresh embryo transfer and FET cycles, using International Classification of Diseases (Tenth Revision) diagnostic codes, national procedural codes, and prescription medication data within the IVF/ICSI pregnancy cohort. FET was subcategorized into artificial cycle-FET (AC-FET), natural cycle-FET (NC-FET), and stimulated cycle-FET (SC-FET) for comparative analyses of the pregnancy, obstetric, and perinatal outcomes. Results: AC-FET was associated with higher risks of hypertensive disorders of pregnancy, preeclampsia, placenta accreta, and postpartum hemorrhage compared with NC-FET; the risk of macrosomia showed no significant differences. SC-FET was associated with a lower risk of miscarriage and higher rate of term birth beyond 37 weeks compared with NCFET. However, SC-FET was associated with elevated risks of gestational hypertension and postpartum hemorrhage when compared to NC-FET. Conclusion The rate of adverse obstetric and perinatal outcomes was higher in AC-FET compared to NC-FET, highlighting NC-FET as a valuable option owing to better maternal and fetal safety. In cases where NC-FET is not feasible, SC-FET presented as a favorable alternative, exhibiting lower miscarriage rates than NC-FET and better obstetric outcomes than AC-FET.
