Selected Articles
1. Data-driven subtypes of polycystic ovary syndrome and their association with clinical outcomes.
Using unsupervised clustering in 11,908 women across five cohorts, the authors identified four reproducible PCOS subtypes with distinct reproductive and metabolic risks. Hyperandrogenic PCOS carried the highest second-trimester pregnancy loss and dyslipidemia risk; the obesity subtype had severe metabolic complications and low live birth but the highest remission; high-SHBG subtype had favorable outcomes; high LH–AMH subtype had the greatest ovarian hyperstimulation risk.
Impact: This reframes PCOS heterogeneity into clinically actionable subtypes validated across international cohorts, enabling risk stratification and tailored management strategies.
Clinical Implications: Clinicians can consider subtype-informed counseling (e.g., miscarriage risk in hyperandrogenic PCOS, ovarian hyperstimulation risk in high LH–AMH) and prioritize metabolic surveillance or fertility strategies accordingly.
Key Findings
- Four reproducible PCOS subtypes were identified via unsupervised clustering across 11,908 women and validated in 5 cohorts.
- Hyperandrogenic PCOS had the highest risk of second-trimester pregnancy loss and dyslipidemia.
- Obesity subtype exhibited the most severe metabolic complications, lowest live birth rates, and the highest PCOS remission rate over follow-up.
- High-SHBG subtype showed favorable reproductive outcomes and the lowest incidence of diabetes and hypertension.
- High LH–AMH subtype had the greatest risk of ovarian hyperstimulation and the lowest remission rate.
Methodological Strengths
- Large, multi-cohort validation (11,908 women across 5 international cohorts)
- Prospective 6.5-year follow-up with IVF treatment data linking subtypes to outcomes
Limitations
- Observational design cannot establish causality of subtype–outcome relationships
- Subtype assignment relies on clinical variable availability and may vary across settings
Future Directions: Prospective interventional studies testing subtype-tailored treatments and external validation in broader, ethnically diverse populations with standardized measurement protocols.
2. Tiered school-family-clinic intervention for childhood obesity prevention in China: A nested cluster randomized controlled trial.
In a cluster RCT of 1,627 third-graders, a tiered school–family–clinic program that combined health education, teacher-led physical activity, individualized family diet guidance, and mHealth support attenuated BMI gain versus usual curriculum over one academic year and lowered obesity prevalence.
Impact: Provides pragmatic, scalable evidence that multilevel, tailored interventions can curb pediatric BMI gain in real-world school settings.
Clinical Implications: Supports integrating school policies, structured activity, family nutrition counseling, and mHealth into community obesity prevention, with tailoring by baseline weight status.
Key Findings
- Cluster randomized trial (n=1,627) showed attenuated BMI gain over one academic year in intervention versus control schools.
- Obesity prevalence decreased in intervention schools compared with controls.
- Intervention intensity was tailored: non-overweight received education/policy (OptiChild), overweight/obese received added structured activity and individualized diet counseling (SCIENT) with mHealth support.
Methodological Strengths
- Cluster randomized controlled design across multiple schools
- Tailored, multicomponent intervention reflecting real-world implementation
Limitations
- Abstract truncation limits visibility into exact effect sizes and behavioral endpoints
- Potential contamination between schools and limited generalizability beyond one city
Future Directions: Full reporting of effect sizes and cost-effectiveness, longer-term follow-up for weight trajectories, and replication across diverse regions and school systems.
3. Screening Natriuretic Peptide Levels Predicts Heart Failure and Death in Individuals With Type 1 and Type 2 Diabetes Without Known Heart Failure.
In 116,466 adults with diabetes and no known heart failure, elevated NT-proBNP or BNP strongly predicted incident heart failure or death over up to 7 years. Adjusted hazard ratios for NT-proBNP were 2.04 and 4.48 in T1D and 1.85 and 3.58 in T2D for 125–300 pg/mL and >300 pg/mL versus <125 pg/mL.
Impact: Provides robust, scalable evidence supporting natriuretic peptide screening to identify high-risk individuals with diabetes who may benefit from early cardioprotective therapies.
Clinical Implications: Incorporating NT-proBNP/BNP screening in diabetes care can flag asymptomatic patients at high risk for heart failure or death, informing initiation or intensification of disease-modifying therapies and cardiology referral.
Key Findings
- Among 116,466 adults with diabetes, 39.6% (T1D) and 42.3% (T2D) had elevated NP (BNP ≥50 pg/mL or NT-proBNP ≥125 pg/mL).
- In T1D, NT-proBNP 125–300 pg/mL and >300 pg/mL were associated with HR 2.04 and 4.48 for incident HF or death versus <125 pg/mL.
- In T2D, NT-proBNP 125–300 pg/mL and >300 pg/mL were associated with HR 1.85 and 3.58 for incident HF or death.
- Findings were consistent when using BNP thresholds.
Methodological Strengths
- Very large cohort with up to 7 years follow-up and multivariable adjustment
- Consistent results across T1D and T2D and across NP analytes (NT-proBNP, BNP)
Limitations
- Retrospective observational design with potential residual confounding and selection bias in NP testing
- Claims/EHR-based data may have misclassification and limited clinical detail
Future Directions: Prospective trials to test NP-guided care pathways in diabetes and cost-effectiveness analyses for screening implementation.
