Increased Risk for Depression After Breast Cancer: A Nationwide Population-Based Cohort Study of Associated Factors in Denmark, 1998-2011
Antidepressant prescriptions and associated factors in men with prostate cancer and their female partners
PURPOSE: To estimate the risk of first-time antidepressant prescriptions as a proxy for depression or anxiety and associated risk factors in patients with prostate cancer and their female partners. METHODS: We followed all men (n = 25,126) and their female cohabiting partners (n = 8785) without a history of cancer or antidepressants from the Danish Diet, Cancer and Health cohort from 1997 to 2014 or 2010, respectively. We estimated the cumulative incidence of first-time antidepressant prescriptions in men with prostate cancer compared with cancer-free men and their respective female partners, using the Danish National Prescription Registry. Sociodemographic, lifestyle-related, and clinical risk factors were assessed using Cox regression models. RESULTS: A total of 1828 men were diagnosed with prostate cancer of whom 15% received antidepressants. The unadjusted hazard ratio of antidepressant prescription was 2.18 (95%CI, 1.92, 2.48) for men with prostate cancer and 1.27 (95%CI, 0.87, 1.85) for their partners, compared with cancer-free men and their partners, respectively. After adjusting for sociodemographic, lifestyle-related, and comorbidity factors, this risk was 2-fold to 4-fold increased among patients, but not significantly increased among partners. Significant risk factors among patients were curative and palliative treatment (vs. active surveillance and watchful waiting), nonlocalized disease, and short education. CONCLUSIONS: Men with prostate cancer have a higher risk of receiving antidepressant medication than cancer-free men. Clinical characteristics can help clinicians in identifying patients at a high risk of depression or anxiety. IMPLICATIONS FOR CANCER SURVIVORS: Men with prostate cancer who experience symptoms of depression or anxiety should seek professional help early on. Patient education could aid in raising awareness and reducing the stigma associated with mental disorders.

Genome-wide by Environment Interaction Study of Stressful Life Events and Hospital-Treated Depression in the iPSYCH2012 Sample
BackgroundResearchers have long investigated a hypothesized interaction between genetic risk and stressful life events in the etiology of depression, but studies on the topic have yielded inconsistent results.MethodsWe conducted a genome-wide by environment interaction study (GWEIS) in 18,532 patients with depression from hospital-based settings and 20,184 population controls. All individuals were drawn from the iPSYCH2012 case-cohort study, a nationally representative sample identified from Danish national registers. Information on stressful life events including family disruption, serious medical illness, death of a first-degree relative, parental disability, and child maltreatment was identified from the registers and operationalized as a time-varying count variable. Hazard ratios for main and interaction effects were estimated using Cox regressions weighted to accommodate the case-cohort design. Our replication sample included 22,880 depression cases and 50,378 controls from the UK Biobank.ResultsThe GWEIS in the iPSYCH2012 sample yielded three novel, genome-wide-significant (p < 5 × 10-8) loci located in the ABCC1 gene (rs56076205, p = 3.7 × 10-10), the AKAP6 gene (rs3784187, p = 1.2 × 10-8), and near the MFSD1 gene (rs340315, p = 4.5 × 10-8). No hits replicated in the UK Biobank (rs56076205: p = .87; rs3784187: p = .93; rs340315: p = .71).ConclusionsIn this large, population-based GWEIS, we did not find any replicable hits for interaction. Future gene-by-stress research in depression should focus on establishing even larger collaborative GWEISs to attain sufficient power
