RESUMO
Importance: Little is known about the risk of suicidal behavior in relation to having a spouse with a cancer diagnosis. Objective: To estimate the risk of suicide attempt and suicide death among spouses of patients with cancer. Design, Setting, and Participants: This nationwide cohort study in Denmark collected registry-based data from 1986 through 2016. Analyses were performed from August 8, 2022, to October 30, 2023. Individuals who had a spouse with a cancer diagnosed during 1986 to 2015 were compared with individuals whose spouse did not have a cancer diagnosis during the same period, randomly selected from the general population and matched by birth year and sex. Exposure: Having a spouse with a cancer diagnosis. Main Outcomes and Measures: Suicide attempt was identified through the Danish National Patient Register and the Danish Psychiatric Central Research Register, whereas suicide death was identified through the Danish Causes of Death Register, through 2016. Flexible parametric and Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% CIs for suicide attempt and suicide death among spouses of patients with a cancer diagnosis. Results: The study included 409â¯338 exposed individuals and 2â¯046â¯682 unexposed individuals (median [IQR] age at cohort entry for both groups, 63 [54-70] years; 55.4% women). During the follow-up, 2714 incident cases of suicide attempt among exposed individuals (incidence rate [IR], 62.6 per 100â¯000 person-years) and 9994 among unexposed individuals (IR, 50.5 per 100â¯000 person-years) were identified, as well as 711 cases of suicide death among the exposed individuals (IR, 16.3 per 100â¯000 person-years) and 2270 among the unexposed individuals (IR, 11.4 per 100â¯000 person-years). An increased risk of suicide attempt (HR, 1.28; 95% CI, 1.23-1.34) and suicide death (HR, 1.47; 95% CI, 1.35-1.60) was observed among spouses of patients with cancer throughout the follow-up. The increased risk was particularly notable during the first year after the cancer diagnosis, with an HR of 1.45 (95% CI, 1.27-1.66) for suicide attempt and 2.56 (95% CI, 2.03-3.22) for suicide death. There was a greater risk increase for both suicide attempt and suicide death when the cancer was diagnosed at an advanced stage or when the spouse died after the cancer diagnosis. Conclusions and Relevance: These findings suggest a need for clinical and societal awareness to prevent suicidal behaviors among spouses of patients with cancer, particularly during the first year following the cancer diagnosis.
RESUMO
OBJECTIVES: We aimed to evaluate the risk of colorectal adenocarcinoma (CRA) associated with long-term use of proton pump inhibitors (PPIs) in a large nationwide cohort. DESIGN: Retrospective cohort study. SETTING: This research was conducted at the national level, encompassing the entire population of Sweden. PARTICIPANTS: This study utilised Swedish national registries to identify all adults who had ≥180 days of cumulative PPI use between July 2005 and December 2012, excluding participants who were followed up for less than 1 year. A total of 754 118 maintenance PPI users were included, with a maximum follow-up of 7.5 years. INTERVENTIONS: Maintenance PPI use (cumulative≥180 days), with a comparator of maintenance histamine-2 receptor antagonist (H2RA) use. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measure was the risk of CRA, presented as standardised incidence ratios (SIRs) with 95% confidence intervals (CIs). Subgroup analyses were performed to explore the impact of indications, tumour locations, tumour stages and the duration of follow-up. A multivariable Poisson regression model was fitted to estimate the incidence rate ratios (IRRs) and 95% CIs of PPI versus H2RA use. RESULTS: Maintenance PPI users exhibited a slightly elevated risk of CRA compared to the general population (SIR 1.10, 95% CI=1.06 to 1.13) for both men and women. Individuals aged 18-39 (SIR 2.79, 95% CI=1.62 to 4.47) and 40-49 (SIR 2.02, 95% CI=1.65 to 2.45) had significantly higher risks than the general population. Right-sided CRA showed a higher risk compared to the general population (SIR 1.26, 95% CI=1.20 to 1.32). There was no significant difference in the risk of CRA between maintenance PPI users and maintenance H2RA users (IRR 1.05, 95% CI=0.87 to 1.27, p<0.05). CONCLUSIONS: Maintenance PPI use may be associated with an increased risk of CRA, but a prolonged observation time is needed.

BACKGROUND: It has been repeatedly shown that men infected by SARS-CoV-2 face a twofold higher likelihood of dying, being hospitalized or admitted to the intensive care unit compared to women, despite taking into account relevant confounders. It has been hypothesized that these discrepancies are related to sex steroid hormone differences with estrogens being negatively correlated with disease severity. The objective of this study was therefore to evaluate COVID-19-related mortality and morbidity among peri- and postmenopausal women in relation to estrogen-containing menopause hormonal treatments (MHT). METHODS: This is a national register-based matched cohort study performed in Sweden between January 1 to December 31, 2020. Study participants comprised women over the age of 53 years residing in Sweden. Exposure was defined as prescriptions of local estrogens, systemic estrogens with and without progestogens, progestogens alone, or tibolone. MHT users were then compared with a matched cohort of non-users. The primary outcome consisted of COVID-19 mortality, whereas the secondary outcomes included inpatient hospitalizations/outpatient visits and confirmed SARS-CoV-2 infection. Multivariable adjusted Cox regression-derived hazard ratios (HRs) were calculated. RESULTS: Use of systemic estrogens alone is associated with increased COVID-19 mortality among older women (aHR 4.73, 1.22 to 18.32), but the association is no longer significant when discontinuation of estrogen use is accounted for. An increased risk for COVID-19 infection is further observed for women using combined systemic estrogens and progestogens (aHR 1.06, 1.00 to 1.13) or tibolone (aHR 1.21, 1.01 to 1.45). Use of local estrogens is associated with an increased risk for COVID-19-related death (aHR 2.02,1.45 to 2.81) as well as for all secondary outcomes. CONCLUSIONS: Systemic or local use of estrogens does not decrease COVID-19 morbidity and mortality to premenopausal background levels. Excess risk for COVID-19 morbidity and mortality was noted among older women and those discontinuing systemic estrogens. Higher risk for death was also noted among women using local estrogens, for which non-causal mechanisms such as confounding by comorbidity or frailty seem to be the most plausible underlying explanations. TRIAL REGISTRATION DETAILS: Not applicable.

BACKGROUND: The psychological toll on parents of a child receiving a cancer diagnosis is known to be high, but there is a knowledge gap regarding suicidal behavior among these parents. The aim of this study was to investigate the risk of suicide attempt and death by suicide in relation to having a child with cancer. METHODS AND FINDINGS: We performed a binational population-based and sibling-controlled cohort study, including all parents with a child diagnosed with cancer in Denmark (1978 to 2016) or Sweden (1973 to 2014), 10 matched unexposed parents per exposed parent (population comparison), and unaffected full siblings of the exposed parents (sibling comparison). Suicide attempt was identified through the Patient Register and the Psychiatric Central Register in Denmark and the Patient Register in Sweden, whereas death by suicide was identified through the Danish Causes of Death Register and the Swedish Causes of Death Register. In population comparison, we used Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of suicide attempt and death by suicide associated with cancer diagnosis of a child, adjusting for sex, age, country of residence, calendar year, marital status, highest attained educational level, household income, history of cancer, history of psychiatric disorder, and family history of psychiatric disorder. The sibling comparison was performed to assess the role of familial confounding in the studied associations. The population comparison consisted of 106,005 exposed parents and 1,060,050 matched unexposed parents, with a median age of 56 at cohort entry and 46.9% male. During the median follow-up of 7.3 and 7.2 years, we observed 613 (incidence rate [IR], 58.8 per 100,000 person-years) and 5,888 (IR, 57.1 per 100,000 person-years) cases of first-onset suicide attempt among the exposed and unexposed parents, respectively. There was an increased risk of parental suicide attempt during the first years after a child's cancer diagnosis (HR, 1.15; 95% CI, [1.03, 1.28]; p = 0.01), particularly when the child was 18 or younger at diagnosis (HR, 1.25; 95% CI, [1.08, 1.46]; p = 0.004), when the child was diagnosed with a highly aggressive cancer (HR, 1.60; 95% CI, [1.05, 2.43]; p = 0.03), or when the child died due to cancer (HR, 1.63; 95% CI, [1.29, 2.06]; p < 0.001). The increased risk did not, however, maintain thereafter (HR, 0.86; 95% CI: [0.75, 0.98]; p = 0.03), and there was no altered risk of parental death by suicide any time after the child's cancer diagnosis. Sibling comparison corroborated these findings. The main limitation of the study is the potential residual confounding by factors not shared between full siblings. CONCLUSIONS: In this study, we observed an increased risk of parental suicide attempt during the first years after a child's cancer diagnosis, especially when the child was diagnosed during childhood, or with an aggressive or fatal form of cancer. There was, however, no altered risk of parental death by suicide at any time after a child's cancer diagnosis. Our findings suggest extended clinical awareness of suicide attempt among parents of children with cancer, especially during the first few years after cancer diagnosis.
