- Background: Adolescence is a period of rapid prostatic growth, yet is understudied for susceptibility for future risk of prostate cancer. We examined cardiorespiratory fitness (CRF) in late adolescence in relation to long-term prostate cancer risk.Methods: A population-based cohort study was conducted of all 699,125 Swedish military conscripts during 1972–1985 (97%–98% of 18-year-old men) in relation to risk of prostate cancer overall, aggressive prostate cancer, and prostate cancer mortality during 1998–2017 (ages 50–65 years). CRF was measured by maximal aerobic workload, and prostate cancer was ascertained using the National Prostate Cancer Register. Muscle strength was examined as a secondary predictor.Results: In 38.8 million person-years of follow-up, 10,782 (1.5%) men were diagnosed with prostate cancer. Adjusting for sociodemographic factors, height, weight, and family history of prostate cancer, high CRF was associated with a slightly increased risk of any prostate cancer [highest vs. lowest quintile: incidence rate ratio (IRR), 1.10; 95% CI, 1.03–1.19; P = 0.008], but was neither significantly associated with aggressive prostate cancer (1.01; 0.85–1.21; P = 0.90) nor prostate cancer mortality (1.24; 0.73–2.13; P = 0.42). High muscle strength also was associated with a modestly increased risk of any prostate cancer (highest vs. lowest quintile: IRR, 1.14; 95% CI, 1.07–1.23; P < 0.001), but neither with aggressive prostate cancer (0.88; 0.74–1.04; P = 0.14) nor prostate cancer mortality (0.81; 0.48–1.37; P = 0.43).Conclusions: High CRF or muscle strength in late adolescence was associated with slightly increased future risk of prostate cancer, possibly related to increased screening, but neither with risk of aggressive prostate cancer nor prostate cancer mortality.Impact: These findings illustrate the importance of distinguishing aggressive from indolent prostate cancer and assessing for potential detection bias.

- AIMS: Women who deliver pre-term have higher future risks of hypertension and ischaemic heart disease, but long-term risks of heart failure (HF) are unknown. We examined these risks in a large national cohort.METHODS AND RESULTS: All 2 201 284 women with a singleton delivery in Sweden during 1973-2015 were followed up for inpatient or outpatient HF diagnoses through 2015. Cox regression was used to compute hazard ratios (HRs) for HF associated with pregnancy duration, adjusting for other maternal factors. Co-sibling analyses assessed for confounding by shared familial (genetic and/or environmental) factors. In 48.2 million person-years of follow-up, 19 922 women were diagnosed with HF (median age: 60.7 years). Within 10 years after delivery, the adjusted HR was 2.96 [95% confidence interval (CI): 2.48-3.53] for HF associated with pre-term (gestational age: <37 weeks) compared with full-term (39-41 weeks) delivery. Stratified HRs were 4.27 (2.54-7.17) for extremely pre-term (22-27 weeks), 3.39 (2.57-4.48) for moderately pre-term (28-33 weeks), 2.70 (2.19-3.32) for late pre-term (34-36 weeks), and 1.70 (1.45-1.98) for early term (37-38 weeks). These HRs declined but remained elevated at 10-19 years (pre-term vs. full term: HR: 2.19; 95% CI: 1.94-2.46), 20-29 years (1.80; 1.67-1.95), and 30-43 years (1.56; 1.47-1.66) after delivery, and were not explained by shared familial factors.CONCLUSION: Pre-term and early term delivery were associated with markedly increased future hazards for HF, which persisted after adjusting for other maternal and familial factors and remained elevated 40 years later. Pre-term and early-term delivery should be recognized as risk factors for HF across the life course.KEY QUESTION: What are the long-term hazards for heart failure (HF) across the life course in women who deliver preterm?KEY FINDING: Preterm and early term delivery were associated with ∼3- and 1.7-fold adjusted hazards for HF in the next 10 years vs. full-term delivery. These hazards declined but remained elevated 40 years later, and were not explained by shared familial factors.TAKE HOME MESSAGE: Preterm and early term delivery were associated with increased future hazards for HF, which persisted for 40 years after adjusting for other maternal and familial factors. Preterm and early term delivery should be recognized as lifelong risk factors for HF.

- Background: Heart failure (HF) has been associated with psychosocial distress, but other long-term mental health sequelae are unclear. Objectives: In this study, the authors sought to determine risks of major depression and suicide, susceptible time periods, and sex-specific differences after HF diagnosis in a large population-based cohort. Methods: A national cohort study was conducted of all 154,572 persons diagnosed with HF at ages 18-75 years during 2002-2017 in Sweden and 1,545,720 age- and sex-matched population-based control subjects who were followed up for major depression and suicide ascertained from nationwide inpatient, outpatient, and death records through 2018. Poisson regression was used to compute incidence rate ratios (IRRs) while adjusting for sociodemographic factors and comorbidities. Results: HF was associated with increased risks of major depression and death by suicide in both men and women, with highest risks in the first 3 months, then declining to modest risks at ≥12 months after HF diagnosis. Within 3 months after HF diagnosis, adjusted IRRs for new-onset major depression were 3.34 (95% CI: 3.04-3.68) in men and 2.78 (95% CI: 2.51-3.09) in women, and for suicide death were 4.47 (95% CI: 2.62-7.62) in men and 2.82 (95% CI: 1.11-7.12) in women. These risks were elevated regardless of age at HF diagnosis. HF was associated with significantly more depression cases in women (P < 0.001). Conclusions: In this large national cohort, HF was associated with substantially increased risks of depression and suicide in men and women, with highest risks occurring within 3 months after HF diagnosis. Men and women with HF need timely detection and treatment of depression and suicidality.

- BACKGROUND: Known risk alleles for epithelial ovarian cancer (EOC) account for approximately 40% of the heritability for EOC. Copy number variants (CNVs) have not been investigated as EOC risk alleles in a large population cohort.METHODS: Single nucleotide polymorphism array data from 13 071 EOC cases and 17 306 controls of White European ancestry were used to identify CNVs associated with EOC risk using a rare admixture maximum likelihood test for gene burden and a by-probe ratio test. We performed enrichment analysis of CNVs at known EOC risk loci and functional biofeatures in ovarian cancer-related cell types.RESULTS: We identified statistically significant risk associations with CNVs at known EOC risk genes; BRCA1 (PEOC = 1.60E-21; OREOC = 8.24), RAD51C (Phigh-grade serous ovarian cancer [HGSOC] = 5.5E-4; odds ratio [OR]HGSOC = 5.74 del), and BRCA2 (PHGSOC = 7.0E-4; ORHGSOC = 3.31 deletion). Four suggestive associations (P < .001) were identified for rare CNVs. Risk-associated CNVs were enriched (P < .05) at known EOC risk loci identified by genome-wide association study. Noncoding CNVs were enriched in active promoters and insulators in EOC-related cell types.CONCLUSIONS: CNVs in BRCA1 have been previously reported in smaller studies, but their observed frequency in this large population-based cohort, along with the CNVs observed at BRCA2 and RAD51C gene loci in EOC cases, suggests that these CNVs are potentially pathogenic and may contribute to the spectrum of disease-causing mutations in these genes. CNVs are likely to occur in a wider set of susceptibility regions, with potential implications for clinical genetic testing and disease prevention.
