Project description:ImportanceSuicide is a leading cause of death among youth aged 10 to 19 years in the United States, with rates traditionally higher in male than in female youth. Recent national mortality data suggest this gap may be narrowing, which warrants investigation.ObjectiveTo investigate trends in suicide rates among US youth aged 10 to 19 years by age group, sex, race/ethnicity, and method of suicide.Design, setting, and participantsCross-sectional study using period trend analysis of US suicide decedents aged 10 to 19 years from January 1, 1975, to December 31, 2016. Data were analyzed for periods defined by statistically significant changes in suicide rate trends. Suicide rates were calculated using population estimates.Main outcomes and measuresPeriod trends in suicide rates by sex and age group were assessed using joinpoint regression. Incidence rate ratios (IRRs) were estimated using negative binomial regression comparing male and female suicide rates within periods.ResultsFrom 1975 to 2016, we identified 85 051 youth suicide deaths in the United States (68 085 male [80.1%] and 16 966 female [19.9%]) with a male to female IRR of 3.82 (95% CI, 3.35-4.35). Following a downward trend until 2007, suicide rates for female youth showed the largest significant percentage increase compared with male youth (12.7% vs 7.1% for individuals aged 10-14 years; 7.9% vs 3.5% for individuals aged 15-19 years). The male to female IRR decreased significantly across the study period for youth aged 10 to 14 years (3.14 [95% CI, 2.74-3.61] to 1.80 [95% CI, 1.53-2.12]) and 15 to 19 years (4.15 [95% CI, 3.79-4.54] to 3.31 [95% CI, 2.96-3.69]). Significant declining trends in the male to female IRR were found in non-Hispanic white youth aged 10 to 14 years (3.27 [95% CI, 2.68-4.00] to 2.04 [95% CI, 1.45-2.89]) and non-Hispanic youth of other races aged 15 to 19 years (4.02 [95% CI, 3.29-4.92] to 2.35 [95% CI, 2.00-2.76]). The male to female IRR for firearms increased significantly for youth aged 15 to 19 years (χ2 = 7.74; P = .02 for sex × period interaction). The male to female IRR of suicide by hanging or suffocation decreased significantly for both age groups (10-14 years: χ2 = 88.83; P < .001 for sex × period interaction and 15-19 years: χ2 = 82.15; P < .001 for sex × period interaction). No significant change was found in the male to female IRR of suicide by poisoning across the study period.Conclusions and relevanceA significant reduction in the historically large gap in youth suicide rates between male and female individuals underscores the importance of interventions that consider unique differences by sex. Future research examining sex-specific factors associated with youth suicide is warranted.

Project description:ImportancePeripartum suicide attempt is a major psychiatric complication associated with pregnancy, but the risk factors remain largely uncertain.ObjectiveTo identify the demographic characteristics and predisposing risks for peripartum suicide attempts and postpartum depression.Design, setting, and participantsThis cohort study used retrospective data on pregnant women who delivered children between April 1, 2016, and March 31, 2021, at 712 hospitals in Japan. The nationwide Diagnosis Procedure Combination database was used.ExposuresPsychiatric and nonpsychiatric medical history, age, alcohol and tobacco use, and obstetric complications and procedures.Main outcomes and measuresData on admissions for prepartum suicide attempt and delivery during the same hospital stay and readmissions for depression or suicide attempt within 1 year post partum were collected. Comparisons of prevalence of each study variable were performed, and multivariable logistic regression analyses were used to determine risk factors.ResultsFrom a total of 39 908 649 hospitalization episodes, 804 617 cumulative pregnant women (median [IQR] age at childbirth, 33 [29-36] years) who delivered at the enrolled hospitals were identified, including 1202 who were admitted for suicide attempt and delivery during the same hospital stay and 111 readmitted for suicide attempt within 1 year post partum. Risk factors associated with prepartum suicide attempts included younger age (adjusted odds ratio [aOR], 0.99; 95% CI, 0.98-1.00) and histories of personality disorder (aOR, 10.81; 95% CI, 5.70-20.49), depression (aOR, 3.97; 95% CI, 2.35-6.70), schizophrenia (aOR, 2.89; 95% CI, 1.52-5.50), and adjustment disorder (aOR, 2.66; 95% CI, 1.07-6.58). Risk factors associated with postpartum suicide attempts included younger age (aOR, 0.96; 95% CI, 0.93-1.00), heavy tobacco use (aOR, 23.09; 95% CI, 5.46-97.62), and histories of alcohol use disorder (aOR, 163.54; 95% CI, 28.30-944.95), personality disorder (aOR, 10.28; 95% CI, 3.29-32.10), anxiety disorders (aOR, 8.13; 95% CI, 2.88-22.98), depression (aOR, 7.27; 95% CI, 2.95-17.91), schizophrenia (aOR, 5.77; 95% CI, 2.17-15.38), bipolar disorder (aOR, 3.98; 95% CI, 1.36-11.67), and insomnia (aOR, 3.17; 95% CI, 1.30-7.78). On sensitivity analysis, risk factors associated with postpartum depression after excluding those with prenatal depression included histories of personality disorder, adjustment disorder, bipolar disorder, insomnia, and anxiety disorders.Conclusions and relevanceThe findings of this cohort study suggest that histories of smoking and prenatal psychiatric disorders are potential risk factors for peripartum suicide attempts and may require additional treatment and prevention interventions.

Project description:ImportanceUnderstanding geographic and community-level factors associated with suicide can inform targeted suicide prevention efforts.ObjectivesTo estimate suicide rates and trajectories, assess associated county-level contextual factors, and explore variation across the rural-urban continuum.Design, setting, and participantsThis cross-sectional study included all individuals aged 25 to 64 years who died by suicide from January 1, 1999, to December 31, 2016, in the United States. Spatial analysis was used to map excess risk of suicide, and longitudinal random-effects models using negative binomial regression tested associations of contextual variables with suicide rates as well as interactions among county-level contextual variables. Data analyses were conducted between January 2019 and July 2019.ExposureCounty of residence.Main outcomes and measuresThree-year county suicide rates during an 18-year period stratified by rural-urban location.ResultsBetween 1999 and 2016, 453 577 individuals aged 25 to 64 years died by suicide in the United States. Decedents were primarily male (349 082 [77.0%]) with 101 312 (22.3%) aged 25 to 34 years, 120 157 (26.5%) aged 35 to 44 years, 136 377 (30.1%) aged 45 to 54 years, and 95 771 (21.1%) aged 55 to 64 years. Suicide rates were higher and increased more rapidly in rural than in large metropolitan counties. The highest deprivation quartile was associated with higher suicide rates compared with the lowest deprivation quartile, especially in rural areas, although this association declined during the period studied (rural, 1999-2001: incidence rate ratio [IRR], 1.438; 95% CI, 1.319-1.568; P < .001; large metropolitan, 1999-2001: 1.208; 95% CI, 1.149-1.270; P < .001; rural, 2014-2016: IRR, 1.121; 95% CI, 1.032-1.219; P = .01; large metropolitan, 2014-2016: IRR, 0.942; 95% CI, 0.887-1.001; P = .06). The presence of more gun shops was associated with an increase in county-level suicide rates in all county types except the most rural (rural: IRR, 1.001; 95% CI, 0.999-1.004; P = .40; micropolitan: IRR, 1.005; 95% CI, 1.002-1.007; P < .001; small metropolitan: IRR, 1.010; 95% CI, 1.006-1.014; P < .001; large metropolitan: IRR, 1.012; 95% CI, 1.006-1.018; P < .001). High social capital was associated with lower suicide rates than low social capital (IRR, 0.917; 95% CI, 0.891-0.943; P < .001). High social fragmentation, an increasing percentage of the population without health insurance, and an increasing percentage of veterans in a county were associated with higher suicide rates (high social fragmentation: IRR, 1.077; 95% CI, 1.050-1.103; P < .001; percentage of population without health insurance: IRR, 1.005; 95% CI, 1.004-1.006; P < .001; percentage of veterans: IRR, 1.025; 95% CI, 1.021-1.028; P < .001).Conclusions and relevanceThis study found that suicide rates have increased across the nation and most rapidly in rural counties, which may be more sensitive to the impact of social deprivation than more metropolitan counties. Improving social connectedness, civic opportunities, and health insurance coverage as well as limiting access to lethal means have the potential to reduce suicide rates across the rural-urban continuum.

Project description:Esophageal squamous cell carcinoma (ESCC) is the sixth most common cause of death worldwide. Incidence rates vary internationally, with the highest rates found in Southern and Eastern Africa, and central Asia. Initial observational studies identified multiple factors associated with an increased risk of ESCC, with subsequent work then focused on developing plausible biological mechanistic associations. The aim of this review is to summarize the role of risk factors in the development of ESCC and propose future directions for further research. A systematic search of the literature was conducted by screening EMBASE, MEDLINE/PubMed, and CENTRAL for relevant publications. In total, 73 studies were included that sought to identify risk factors associated with the development of esophageal squamous cell carcinoma. Risk factors were divided into seven subcategories: genetic, dietary and nutrition, gastric atrophy, infection and microbiome, metabolic, epidemiological and environmental and other risk factors. Risk factors from each subcategory were summarized and explored with mechanistic explanations for these associations. This review highlights several current risk factors of ESCC. These risk factors were explored, and explanations dissected. Most studies focused on investigating genetic and dietary and nutritional factors, whereas this review identified other potential risk factors that have yet to be fully explored. Furthermore, there is a lack of literature on the association of these risk factors with tumor factors and disease prognosis. Further research to validate these results and their effects on tumor biology is absolutely necessary.

Project description:(1) Background: China has the highest esophageal squamous cell carcinoma (ESCC) incidence areas in the world, with some areas of incidence over 100 per 100,000. Despite extensive public health efforts, its etiology is still poorly understood. This study aims to review and summarize past research into potential etiologic factors for ESCC in China. (2) Methods: Relevant observational and intervention studies were systematically extracted from four databases using key terms, reviewed using Rayyan software, and summarized into Excel tables. (3) Results: Among the 207 studies included in this review, 129 studies were focused on genetic etiologic factors, followed by 22 studies focused on dietary-related factors, 19 studies focused on HPV-related factors, and 37 studies focused on other factors. (4) Conclusions: ESCC in China involves a variety of factors including genetic variations, gene-environment interactions, dietary factors like alcohol, tobacco use, pickled vegetables, and salted meat, dietary behavior such as hot food/drink consumption, infections like HPV, poor oral health, gastric atrophy, and socioeconomic factors. Public health measures should prioritize genetic screening for relevant polymorphisms, conduct comprehensive investigations into environmental, dietary, and HPV influences, enhance oral health education, and consider socioeconomic factors overall as integral strategies to reduce ESCC in high-risk areas of China.

Project description:BackgroundThe suicide risk was higher in kidney cancer patients than in the general population. The purpose of this study was to characterize the suicide rates among kidney cancer patients and to identify the potential risk factors associated with suicide from the Surveillance, Epidemiology, and End Results (SEER) database.MethodsKidney cancer patients were identified from the SEER database during 1973-2015. Suicide rates and standardized mortality ratios (SMRs) of this population were calculated, and the US general population during 1981-2015 was chosen as a reference. Univariable and multivariable Cox regression were performed to find out potential risk factors of suicide.ResultsThere were 207 suicides identified among 171 819 individuals with kidney cancer observed for 948 272 person-years. The suicide rate was 21.83 per 100 000 person-years, and SMR was 1.83 (95% CI: 1.59-2.10). On Cox regression, diagnosis in early years (1973-1982 vs 2003-2015, HR: 2.03, 95% CI: 1.01-4.11, P = 0.048; 1983-1992 vs 2003-2015, HR: 1.99, 95% CI: 1.18-3.35, P = 0.010), male sex (vs female sex, HR: 4.43, 95% CI: 2.95-6.65, P < 0.001), unmarried status (vs married status, HR: 2.54, 95% CI: 1.91-3.38, P < 0.001), non-black race (white race vs black race, HR: 4.47, 95% CI: 2.09-9.58, P < 0.001; other races vs black race, HR: 3.01, 95% CI: 1.08-8.37, P = 0.035), higher histologic grade (grade IV vs grade I, HR: 3.27, 95% CI: 1.50-7.13, P = 0.003; grade III vs grade I, HR: 2.13, 95% CI: 1.19-3.81, P = 0.011) and cancer-directed surgery not performed (vs performed, HR: 2.78, 95% CI: 1.52-5.11, P < 0.001) were independent risk factors of suicide among kidney cancer patients.ConclusionsDiagnosis in early years, male sex, unmarried status, non-black race, higher histologic grade, and cancer-directed surgery not performed were significantly associated with suicide among kidney cancer patients. In order to prevent suicidal death, clinicians should pay more attention to patients with high-risk factors of suicide.

Project description:ObjectivePatients visiting the emergency department (ED) after a suicide attempt are generally assessed for suicide risk by psychiatric residents. Psychiatric residents' competence in evaluating the risk posed by the patients who attempted suicide is critical to preventing suicide.MethodsWe investigated factors considered important by psychiatric residents when evaluating suicide risk. This study included 140 patients admitted to the ED after attempting suicide. Psychiatric residents rated patients' severity of current and future suicide risk as low/moderate/high using the Brief Emergency Room Suicide Risk Assessment (BESRA). The association between each BESRA variable and level of suicide risk was analyzed.ResultsMany factors were commonly considered important in evaluating the severity of current and future suicide risk. However, the following factors were only associated with future suicide risk: female gender, having no religion, family psychiatric history, history of axis I disorders, having a will, harboring no regrets, and social isolation.ConclusionPsychiatric residents use diverse factors when assessing suicide risk. Psychiatric residents might put more emphasis on non-modifiable demographic and clinical factors, concrete evidence showing suicide determination, and social isolation to assess the risk of future suicide.

Project description:The aim of the present study was to investigate the survival and prognostic factors of patients who were with advanced esophageal squamous cell carcinoma (ESCC) and developed an esophageal fistula. The data from 221 patients with advanced ESCC developed esophageal fistula from January 2008 to December 2017 at the Harbin Medical University Cancer Hospital was retrospectively analyzed. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated by the Cox proportional hazard models. The median survival time after a diagnosis of the esophageal fistula was calculated using the Kaplan-Meier method. We found that the pathogens infected by patients are common bacteria in nosocomial infection. Besides, the incidence rate of esophagomediastinal fistula was the highest (54.2%) in the lower third of the esophagus. Kaplan-Meier analysis revealed a median survival time of 11.00 months and a median post-fistula survival time of 3.63 months in patients who developed esophageal fistula in advanced esophageal cancer. In the univariate analysis, gender, therapies for ESCC before the development of fistula, type of esophageal fistula, treatment of esophageal fistula and hemoglobin (Hb) level were the factors with significant prognostic value. Gender, type of esophageal fistula and Hb level were identified as independent prognostic factors in further multivariate analysis. In summary, our study demonstrated that several factors are significantly related to patients with esophageal fistula and should be concerned about in clinical practice.

Project description:Objective: To determine whether predictions of suicide risk from machine learning models identify unexpected patients or patients without medical record documentation of traditional risk factors.Methods: The study sample included 27,091,382 outpatient mental health (MH) specialty or general medical visits with a MH diagnosis for patients aged 11 years or older from January 1, 2009, to September 30, 2017. We used predicted risk scores of suicide attempt and suicide death, separately, within 90 days of visits to classify visits into risk score percentile strata. For each stratum, we calculated counts and percentages of visits with traditional risk factors, including prior self-harm diagnoses and emergency department visits or hospitalizations with MH diagnoses, in the last 3, 12, and 60 months.Results: Risk-factor percentages increased with predicted risk scores. Among MH specialty visits, 66%, 88%, and 99% of visits with suicide attempt risk scores in the top 3 strata (respectively, 90th-95th, 95th-98th, and ≥ 98th percentiles) and 60%, 77%, and 93% of visits with suicide risk scores in the top 3 strata represented patients who had at least one traditional risk factor documented in the prior 12 months. Among general medical visits, 52%, 66%, and 90% of visits with suicide attempt risk scores in the top 3 strata and 45%, 66%, and 79% of visits with suicide risk scores in the top 3 strata represented patients who had a history of traditional risk factors in the last 12 months.Conclusions: Suicide risk alerts based on these machine learning models coincide with patients traditionally thought of as high-risk at their high-risk visits.

Project description:Esophageal microbiota plays important roles in esophageal squamous cell carcinoma (ESCC). The aims of this study were to clarify the changes in the bacterial community during ESCC development and identify latent pathogenic bacteria which may contribute to esophageal carcinogenesis and progression. Fresh tumor and nontumor esophageal mucosal samples were collected from 31 men with ESCC. High-throughput 16s rRNA sequencing was performed, and the operational taxonomic unit data and bacterial classification annotation were obtained and analyzed. The Ace, Chao, Shannon, Simpson indexes, and operational taxonomic unit numbers were higher in nontumor tissues than in tumor tissues, although without statistical significance. There were 4 phyla and 28 genera found to show significant differences between tumor and nontumor samples. The general probiotic Lactobacillus was 1.98-fold higher in nontumor tissues, while the general pathogenic genera Fusobacterium was 4.35-fold higher in tumor tissues. For tumor tissue samples, the genera Treponema and Brevibacillus were significantly higher in N1 and N2 stages, respectively, and Acinetobacter was significantly higher in T3 stage. For nontumor tissues, the genus Fusicatenibacter was significantly higher in T2 stage, and Corynebacterium, Aggregatibacter, Saccharimonadaceae-TM7x, and Cupriavidus were significantly higher in T4 stage. Additionally, bacteria related to nitrotoluene degradation were enriched in nontumor tissues, while bacteria related to base excision repair were enriched in tumor tissues. The relative abundance of several phyla and genera are different between tumor and nontumor tissue samples. The altered bacterial microbiota is correlated with different tumor stages and some microbes may take part in the carcinogenesis and development of ESCC.
