Trends in mortality related to venous thromboembolism in the European Union, 2012-2020.

We sought to assess the sex- and age-specific trends in venous thromboembolism (VTE) mortality in the 27 European Union Member States (EU-27) between years 2012 and 2020. Data on cause-specific deaths and population numbers by sex for each country of the EU-27 were retrieved through the publicly available European Statistical Office (EUROSTAT) dataset for the years 2012-2020. VTE-related deaths were ascertained when ICD-10 codes I26, I80, and I82.9 were listed as the primary cause of death in the medical death certificate. To calculate annual trends, we assessed the average annual percent change (AAPC) with relative 95% confidence intervals (CIs) using Joinpoint regression. During the study period, 96,037 (55,278 males and 40,759 females) died for VTE. The age-adjusted mortality rate (AAMR) linearly declined from 2.86 (95% CI 2.84-2.90) deaths per 100,000 individuals in 2012 to 2.53 (95% CI 2.50-2.56) deaths per 100,000 population in 2020 [AAPC: - 2.1% (95% CI - 3.6 to - 0.6), p = 0.001] without differences between sexes (p = 0.60). The higher AAMR was observed in some eastern European countries such as Bulgaria, Czech Republic, and Lithuania. On the contrary, the lower AAMR was mainly clustered in the Mediterranean area (Italy, Spain, and Cyprus). Over the last decade, the age-adjusted VTE-related mortality has been continuously declining in most of the in EU-27 Member States. However, some disparities still exist between western and eastern European countries.

Long-term outcomes of 5-year survivors without recurrence after the complete resection of non-small cell lung cancer after lobectomy: a landmark analysis in consideration of competing risks.

Among non-small cell lung cancers (NSCLC), 5years is a benchmark in cancer control and treatment, but a certain percentage of cases recur after 5years. The long-term post-recurrence outcomes remain controversial. To examine the accurate prognostic factors associated with survival and cancer recurrence among 5-year survivors, a landmark analysis that considered competing risks was performed. Complete resection of NSCLC was performed in 2482 patients between January 2003 and December 2015. A total of 1431 patients were 5-year survivors without recurrence. A landmark time analysis was applied to the overall survival (OS) and recurrence-free survival (RFS) from 5years after surgery, and the findings were calculated using the Kaplan-Meier method. The cumulative incidence of cause-specific death and recurrence was estimated using the cumulative incidence function, while carefully considering the competing risks. Postoperative recurrence was detected in 732 patients, of whom 68 (9.3%) had recurrence after 5years. The median follow-up period was 8.2 years. In the competing risk analysis, the independent poor prognostic factors associated with cause-specific death were age ≥ 75 years, lymph node metastasis and pleural invasion. Patients requiring a follow-up for > 5years were aged ≥ 75years and had either lymph node metastasis or pleural invasion.

Variability in Alzheimer's disease mortality from European vital statistics, 2012-2020.

Data regarding the trends in Alzheimer's disease (AD) mortality in the modern European Union (EU-27) member states are lacking. We assess the sex- and age-specific trends in AD mortality in the EU-27 member states between years 2012 and 2020. Data on cause-specific deaths and population numbers by sex for each country of the EU-27 were retrieved through publicly available European Statistical Office (EUROSTAT) dataset from 2012 to 2020. AD-related deaths were ascertained when the ICD-10 code G30 was listed as the primary cause of death in the medical death certificate. To calculate annual trends, we assessed the average annual percent change (AAPC) with relative 95% confidence intervals (CIs) using Joinpoint regression. During the study period, 751,493 deaths (1.7%, 233,271 males and 518,222 females) occurred in the EU-27 because of AD. Trends in the proportion of AD-related deaths per 1000 total deaths slightly increased from 16.8% to 17.5% (p for trend <0.001). The age-adjusted mortality rate was higher in women over the entire study period. Joinpoint regression analysis revealed a stagnation in age-adjusted AD-related mortality from 2012 to 2020 among EU-27 Member States (AAMR: -0.1% [95% CI: -1.8-1.79], p=0.94). Stratification by Country showed relevant regional disparities, especially in the Northern and Eastern EU-27 member states. Over the last decade, the age-adjusted AD-related mortality rate has plateaued in EU-27. Important disparities still exist between Western and Eastern European countries.

Regional variation in cause of death in patients with type 2 diabetes: Insights from EXSCEL

AimsType 2 diabetes (T2D) is a risk factor for cardiovascular and non-cardiovascular mortality. However, global distribution of cause-specific deaths in T2D is poorly understood. We characterized cause-specific deaths by geographic region among individuals with T2D at risk for cardiovascular disease (CVD). Methods and resultsThe international EXSCEL trial included 14,752 participants with T2D (73% with established CVD). We identified the proportion of deaths over 5-year follow-up attributed to cardiovascular and non-cardiovascular causes, and associated risk factors. During median 3.2-year follow-up, 1,091 (7.4%) participants died. Adjudicated causes of death were 723 cardiovascular (66.3% of deaths), including 252 unknown, and 368 non-cardiovascular (33.7%). Most deaths occurred in North America (N = 356/9.6% across region) and Eastern Europe (N = 326/8.1%), with fewest in Asia/Pacific (N = 68/4.4%). The highest proportional cause-specific deaths by region were sudden cardiac in Asia/Pacific (23/34% of regional deaths) and North America (86/24%); unknown in Eastern Europe (90/28%) and Western Europe (39/21%); and non-malignant non-cardiovascular in Latin America (48/31%). Cox proportional hazards model for adjudicated causes of death showed prognostic risk factors (hazard ratio [95% CI]) for cardiovascular and non-cardiovascular deaths, respectively: heart failure 2.04 (1.72-2.42) and 1.86 (1.46-2.39); peripheral artery disease 1.83 (1.54-2.18) and 1.78 (1.40-2.26); and current smoking status 1.61 (1.29-2.01) and 1.77 (1.31-2.40). ConclusionsIn a contemporary T2D trial population, with and without established CVD, leading causes of death varied by geographic region. Underlying mechanisms leading to variability in cause of death across geographic regions and its impact on clinical trial endpoints warrant future research.

Mortality and cancer incidence in perfluorooctanesulfonyl fluoride production workers.

Exposure to per- and polyfluoroalkyl substances (PFAS) has been associated with several health outcomes, though few occupationally-exposed populations have been studied. We evaluated mortality and cancer incidence in a cohort of perfluorooctanesulfonyl fluoride-based specialty chemical manufacturing workers. The cohort included any employee who ever worked at the facility from 1961 to 2010 (N = 4045), with a primary interest in those who had 365 cumulative days of employment (N = 2659). Vital status and mortality records were obtained through 2014 and the cohort was linked to state cancer registries to obtain incident cancer cases from 1995 to 2014. Cumulative exposure was derived from a comprehensive exposure reconstruction that estimated job-specific perfluorooctanesulfonate (PFOS)-equivalents (mg/m3 ) exposure. Overall and exposure-specific standardized mortality ratios (SMR) were estimated in reference to the US population. Hazard ratios (HRs) and 95% confidence interval (CI) for cumulative PFOS-equivalent exposure (log2 transformed) were estimated within the cohort for specific causes of death and incident cancers using a time-dependent Cox model. Death rates were lower than expected except for cerebrovascular disease (SMR = 2.42, 95% CI = 1.25-4.22) and bladder cancer (SMR = 3.91, 95% CI = 1.07-10.02) in the highest exposure quartile. Within the cohort, the incidence of bladder, colorectal, and pancreatic cancer were positively associated with exposure, however except for lung cancer (HR = 1.05, 95% CI = 1.00-1.11) the CIs did not exclude an HR of 1. This study provides some evidence that occupational exposure to PFOS is associated with bladder and lung cancers and with cerebrovascular disease.

Risk of death following chikungunya virus disease in the 100 Million Brazilian Cohort, 2015–18: a matched cohort study and self-controlled case series

Chikungunya virus outbreaks have been associated with excess deaths at the ecological level. Previous studies have assessed the risk factors for severe versus mild chikungunya virus disease. However, the risk of death following chikungunya virus disease compared with the risk of death in individuals without the disease remains unexplored. We aimed to investigate the risk of death in the 2 years following chikungunya virus disease. We used a population-based cohort study and a self-controlled case series to estimate mortality risks associated with chikungunya virus disease between Jan 1, 2015, and Dec 31, 2018, in Brazil. The dataset was created by linking national databases for social programmes, notifiable diseases, and mortality. For the matched cohort design, individuals with chikungunya virus disease recorded between Jan 1, 2015, and Dec 31, 2018, were considered as exposed and those who were arbovirus disease-free and alive during the study period were considered as unexposed. For the self-controlled case series, we included all deaths from individuals with a chikungunya virus disease record, and each individual acted as their own control according to different study periods relative to the date of disease. The primary outcome was all-cause natural mortality up to 728 days after onset of chikungunya virus disease symptoms, and secondary outcomes were cause-specific deaths, including ischaemic heart diseases, diabetes, and cerebrovascular diseases. In the matched cohort study, we included 143 787 individuals with chikungunya virus disease who were matched, at the day of symptom onset, to unexposed individuals using sociodemographic factors. The incidence rate ratio (IRR) of death within 7 days of chikungunya symptom onset was 8·40 (95% CI 4·83-20·09) as compared with the unexposed group and decreased to 2·26 (1·50-3·77) at 57-84 days and 1·05 (0·82-1·35) at 85-168 days, with IRR close to 1 and wide CI in the subsequent periods. For the secondary outcomes, the IRR of deaths within 28 days after disease onset were: 1·80 (0·58-7·00) for cerebrovascular diseases, 3·75 (1·33-17·00) for diabetes, and 3·67 (1·25-14·00) for ischaemic heart disease, and there was no evidence of increased risk in the subsequent periods. For the self-controlled case series study, 1933 individuals died after having had chikungunya virus disease and were included in the analysis. The IRR of all-cause natural death within 7 days of symptom onset of chikungunya virus disease was 8·75 (7·18-10·66) and decreased to 1·59 (1·26-2·00) at 57-84 days and 1·09 (0·92-1·29) at 85-168 days. For the secondary outcomes, the IRRs of deaths within 28 days after disease onset were: 2·73 (1·50-4·96) for cerebrovascular diseases, 8·43 (5·00-14·21) for diabetes, and 2·38 (1·33-4·26) for ischaemic heart disease, and there was no evidence of increased risk at 85-168 days. Chikungunya virus disease is associated with an increased risk of death for up to 84 days after symptom onset, including deaths from cerebrovascular diseases, ischaemic heart diseases, and diabetes. This study highlights the need for equitable access to approved vaccines and effective anti-chikungunya virus therapeutics and reinforces the importance of robust vector-control efforts to reduce viral transmission.

Causes of death after first time venous thromboembolism

BackgroundCauses of death after first time community-acquired venous thromboembolism (VTE) diagnosed in unselected patients at the emergency department (ED) was investigated.Materials and methodsThe study consists of all patients > 18 years of age who had a visit for any medical reason to any of 5 different ED in Stockholm County, Sweden from 1st January 2016 to 31st December 2017. We have identified all patients with a first registered incident VTE; deep vein thrombosis (DVT) and/or pulmonary embolism (PE) during the study period. Cox regression models were used to estimate hazards ratios (HR) with 95% confidence intervals (CIs) for all-cause mortality and cause-specific death in patients with DVT or PE using all other patients as the reference group.ResultsIn total, 359,884 patients had an ED visit during the study period of whom about 2.1% were diagnosed with VTE (DVT = 4,384, PE = 3,212). The patients with VTE were older compared to the control group. During a mean follow up of 2.1 years, 1567 (21%) and 23,741(6.7%) patients died within the VTE and reference group, respectively. The adjusted risk of all-cause mortality was nearly double in patients with DVT (HR 1.7; 95% CI, 1.5–1.8) and more than 3-fold in patients with PE (HR 3.4; 95% CI, 3.1–3.6). While the risk of cancer related death was nearly 3-fold in patient with DVT (HR 2.7; 95% CI, 2.4–3.1), and 5-fold in PE (HR 5.4; 95% CI, 4.9-6.0 respectively). The diagnosis of PE during the ED visit was associated with a significantly higher risk of cardiovascular death (HR 2.2; 95% CI, 1.9–2.6).ConclusionPatients with VTE have an elevated risk of all-cause mortality, including cardiovascular death.

Pregnancy-related maternal mortality in the state of Georgia: Timing and causes of death.

The maternal mortality rate in the United States is high and disparities among non-Hispanic White and non-Hispanic Black women remain. In the State of Georgia, the pregnancy-related death rate is among the worst in the nation. To examine current pregnancy-related deaths in the State of Georgia using measures of timing and cause-specific mortality across maternal sociodemographic characteristics. This cross-sectional study of pregnancy-related deaths in Georgia was based on 2016-2019 maternal mortality data obtained from the Georgia Department of Public Health. Our study analysis involved complete-case data of maternal deaths identified as pregnancy-related deaths (n = 129). Statistical analyses included two distinct population-level measures: (a) timing (i.e. during pregnancy, 0 to 60 days, 61 to 180 days, and 181 to 365 days postpartum) and (b) cause-specific deaths patterned by sociodemographic groups of women and by rural and urban county of residence. Categorical variables were compared using the Chi square or Fisher's exact test and presented as numbers and percentages. A post hoc power analysis was conducted to inform whether there was sufficient power to detect statistically significant effects given available sample sizes. Among a total of 129 pregnancy-related deaths, 30 (23.3%) deaths occurred during pregnancy and 63 (48.8%) deaths occurred within the first 60 days postpartum. Pregnancy-related deaths were disproportionally common among non-Hispanic Black, 25 to 34 years old, and poorly educated women. Three leading underlying causes, cardiomyopathy (22.7%), hemorrhage (21.6%), and cardiovascular or coronary disease (20.4%), accounted for about 65% of all pregnancy-related deaths. Mental health conditions were common causes of death among non-Hispanic White women during pregnancy and in late postpartum. Continued monitoring, collecting and analyzing reliable data will help identify root causes and find ways to eliminate the disproportionate burden of pregnancy-related deaths in the State of Georgia.

Trends in atrial fibrillation-related mortality in Europe, 2008-2019.

Update data regarding the atrial fibrillation (AF)-related mortality trend in Europe remain scant. We assess the age- and sex-specific trends in AF-related mortality in the European states between the years 2008 and 2019. Data on cause-specific deaths and population numbers by sex for European countries were retrieved through the publicly available World Health Organization mortality dataset for the years 2008-2019. Atrial fibrillation-related deaths were ascertained when the International Classification of Diseases, 10th Revision code I48 was listed as the underlying cause of death in the medical death certificate. To calculate annual trends, we assessed the average annual % change (AAPC) with relative 95% confidence intervals (CIs) using Joinpoint regression. During the study period, 773 750 AF-related deaths (202 552 males and 571 198 females) occurred in Europe. The age-adjusted mortality rate (AAMR) linearly increased from 12.3 (95% CI: 11.2-12.9) per 100 000 population in 2008 to 15.3 (95% CI: 14.7-15.7) per 100 000 population in 2019 [AAPC: +2.0% (95% CI: 1.6-3.5), P<0.001] with a more pronounced increase among men [AAPC: +2.7% (95% CI: 1.9-3.5), P<0.001] compared with women [AAPC: +1.7% (95% CI: 1.1-2.3), P<0.001] (P for parallelism 0.01). Higher AAMR increases were observed in some Eastern European countries such as Latvia, Lithuania, and Poland, while the lower increases were mainly clustered in Central Europe. Over the last decade, the age-adjusted AF-related mortality has increased in Europe, especially among males. Disparities still exist between Western and Eastern European countries.

P1133 Relative survival and cause-specific mortality of a Chilean Inflammatory Bowel Disease cohort

Abstract Background In the past two decades, multiple studies have shown an improvement in outcomes of inflammatory bowel disease (IBD) patients including a decreasing mortality associated with new treatments, surveillance, and healthcare support. There are no large studies in Latin-American countries addressing survival and death causes in IBD patients. We aimed to assess relative survival (RS) and causes of death in Chilean IBD patients. Methods IBD patients treated in a tertiary reference centre (Pontificia Universidad Católica of Chile, Santiago, Chile) since January 1990 were included in a local database. Death certificates were analysed to obtain the date and specific cause of death. The recorded time started on the date of definitive diagnosis and lasted until death or censoring on December 31st, 2020. The survival of IBD patients was compared with the life expectancy of the Chilean general population based on official life tables collected in the Human Mortality Database (www.mortality.org). The RS was computed using the Ederer II method implemented in the RELSURV package of the R software. A RS greater than 1.0 indicates that the analysed cohort has a higher survival than the expected survival of the reference population for the same age, sex and date at which age was coded. Inclusion of 1.0 within 95% CI indicates no difference between observed and expected survival. Data were also expressed graphically as the observed cumulative survival curves over time and the 95% confidence interval (CI) and compared to the reference population. Results We included 1,289 IBD patients with a media age at diagnosis of 35.9±14 years, 40.9% males and a follow-up of 22,525 patients-year. Ulcerative Colitis, Crohn’s disease and IBD unclassified patients comprised 50.2%, 43.1% and 6.7% of the cohort, respectively. A total of 106 patients (8.9%) died during the study period. Compared with the general population, the survival of IBD patients was higher (RS = 1.04; 95% CI: 1.02-1.07) at 20 years of follow-up (Table and Figure). This higher RS in IBD patients was observed in males and females, as well as CD patients and IBD patients older than 40-year-old (Table). The main causes of death in IBD patients were cancer (34%), infections (27.7%) and cardiovascular diseases (21.3%). Conclusion Compared to the general population, a higher long-term survival was observed in this large cohort of Chilean IBD patients. These findings may be due to a closer surveillance of this group of patients. Causes of death mirrored those in previously reported cohorts; therefore, a special care should be pay on their prevention in Latin-American countries as well.

All-Cause and Cause-Specific Mortality Among Low-Risk Differentiated Thyroid Cancer Survivors in the United States.

Background: Despite the excellent disease-specific survival associated with low-risk differentiated thyroid cancer (DTC), its diagnosis and management have been linked to patient concerns about cancer recurrence, treatment-related health risks, and mortality. Lack of information regarding long-term health outcomes can perpetuate these concerns. Therefore, we assessed all-cause and cause-specific mortality in a large cohort of individuals diagnosed with low-risk DTC. Methods: From the U.S. Surveillance, Epidemiology, and End Results-12 cancer registry database (1992-2019), we identified 51,854 individuals (81.8% female) diagnosed with first primary DTC at low risk of recurrence (≤4 cm, localized). We estimated cause-specific cumulative mortality by time since diagnosis, accounting for competing risks. Standardized mortality ratios (SMRs) and CIs were used to compare observed mortality rates in DTC patients with expected rates in the matched U.S. general population, overall and by time since DTC diagnosis. We used Cox proportional hazards models to examine associations between radioactive iodine (RAI) treatment and cause-specific mortality. Results: During follow-up (median = 8.8, range 0-28 years), 3467 (6.7%) deaths were recorded. Thyroid cancer accounted for only 4.3% of deaths (n = 148). The most common causes of death were malignancies (other than thyroid cancer) (n = 1031, 29.7%) and cardiovascular disease (CVD; n = 912, 26.3%). The 20-year cumulative mortality rate from thyroid cancer, malignancies (other than thyroid or nonmelanoma skin cancer), and CVD was 0.6%, 4.6%, and 3.9%, respectively. Lower than expected mortality was observed for all causes excluding thyroid cancer (SMR = 0.69 [CI 0.67-0.71]) and most specific causes, including all malignancies combined (other than thyroid cancer; SMR = 0.80 [CI 0.75-0.85]) and CVD (SMR = 0.64 [CI 0.60-0.69]). However, mortality rates were elevated for specific cancers, including pancreas (SMR = 1.58 [CI 1.18-2.06]), kidney and renal pelvis (SMR = 1.85 [CI 1.10-2.93]), and brain and other nervous system (SMR = 1.62 [CI 0.99-2.51]), and myeloma (SMR = 2.35 [CI 1.46-3.60]) and leukemia (SMR = 1.62 [CI 1.07-2.36]); these associations were stronger ≥10 years after diagnosis. RAI was not associated with risk of cause-specific death, but numbers of events were small and the range of administered activities was likely narrow. Conclusions: Overall, our findings provide reassurance regarding low overall and cause-specific mortality rates in individuals with low-risk DTC. Additional research is necessary to confirm and understand the increased mortality from certain subsequent cancers.

An investigation of 3M Cordova, IL production worker's per- and polyfluoroalkyl substances biomonitoring results and mortality experience

Per- and polyfluoroalkyl substances (PFAS) are a wide-ranging group of chemicals that have been used in a variety of polymer and surfactant applications. While 3M Cordova, Illinois was not one of 3M's primary manufacturing facilities for the legacy long-chain PFAS (PFOS, PFOA, PFHxS), it has been a major manufacturing site for short-chain PFAS (compounds that are or may degrade to PFBS or PFBA). The purpose of this research focused on: 1) an analysis of biomonitoring data of employees and retirees, and 2) an analysis of the cohort mortality of workers from 1970 to 2018. Employees had higher PFBS and PFBA serum concentrations than the retirees, while retirees had higher concentrations for PFOS, PFOA, and PFHxS. Compared to the 2017–2018 NHANES data, employees’ PFOS and PFHxS concentrations in 2022 were two-fold higher, with PFOA levels comparable. These NHANES data did not include serum PFBS or PFBA. Cross-sectional trends of PFOS and PFOA levels from 1997 to 2022 showed PFOS declined from 151 ng/mL to 10.4 ng/mL. Similarly, PFOA decreased from 100 ng/mL to 1.5 ng/mL. A longitudinal analysis of 48 participants with measurements in both 2006 and 2022 showed concentrations decreased by 74% for PFOS and 90% for PFOA. In the mortality study, 1707 employees who worked 1 day or longer were followed for an average of 25.6 years and had 143 (8%) deaths. There were no significantly elevated risks for any specific cause of death, regardless of latency period (0 or 15 years). While no specific PFAS exposures were examined, worker mortality experience (1970–2018) was analyzed by major departments representing primary work areas. Employees and retirees at the Cordova facility continue to have elevated PFOS and PFHxS serum concentrations compared to the general population, however, their legacy PFAS concentrations have declined over time, consistent with the estimated serum elimination half-lives of these PFAS in humans assuming nominal ambient exposures. For PFBS and PFBA, the results indicated no long-term accumulation in the blood likely due to their short serum elimination half-lives. After nearly 50 years of follow-up, this Cordova workforce showed no increased risk of mortality from cancer or any other specific cause of death.

Pleural effusion portends a poor prognosis in patients on continuous ambulatory peritoneal dialysis.

Pleural effusion is not an infrequent complication in patients undergoing continuous ambulatory peritoneal dialysis. However, there is not adequate data to evaluate pleural effusion and prognosis in clinical practice. In this study, we validated this potential association by a multicenter cohort. We screened 1,162 patients who met the inclusion criteria with PD. According to the existence of pleural effusion on stable dialysis (4-8 weeks after dialysis initiation), the participants were divided into pleural effusion and non-pleural effusion groups. The hazard ratios (HRs) of all-cause and cause-specific death were estimated with adjustment for demographic characteristics and multiple potential clinical confounders. Subgroup analysis and propensity score matching (PSM) were used to further verify the robustness of the correlation between hydrothorax and prognosis. Pleural effusion was found in 8.9% (104/1162) of PD individuals. After adjusting for the confounding factors, patients with pleural effusion had significantly increased HRs for all-cause death was 3.06 (2.36-3.96) and cardiovascular death was 3.78 (2.67-5.35) compared to those without pleural effusion. However, it was not associated with infectious and other causes of death. After PSM, the HR of all-cause mortality was 3.56 (2.28-5.56). The association trends were consistent in the subgroup sensitivity analysis. Pleural effusion is not rare in PD, and is significantly associated with overall and cardiovascular mortality, which is independent of underlying diseases and clinically relevant indicators.

All-cause mortality before and after DAA availability among people living with HIV and HCV: An international comparison between 2010 and 2019

BackgroundAmong people living with HIV and hepatitis C virus (HCV), people who inject drugs (PWID) have historically experienced higher mortality rates. Direct-acting antivirals (DAA), which have led to a 90 % HCV cure rate independently of HIV co-infection, have improved mortality rates. However, DAA era mortality trends among PWID with HIV/HCV remain unknown. Using data from the International Collaboration on Hepatitis C Elimination in HIV Cohorts (InCHEHC), we compared pre/post-DAA availability mortality changes in three groups: PWID, men who have sex with men (MSM), and all other participants. MethodsWe included InCHEHC participants with HIV/HCV followed between 2010 and 2019 in Canada, France, the Netherlands, Spain, and Switzerland. All-cause mortality hazard was compared in the three groups, using Cox proportional hazards regression models adjusted for sex, age, advanced fibrosis/cirrhosis, and pre/post DAA availability. ResultsOf the 11,029 participants, 76 % were men, 46 % were PWID, baseline median age was 46 years (interquartile range [IQR] = 40;51), and median CD4 T-cell count was 490 cells/mm3 (IQR = 327;689). Over the study period (median follow-up = 7.2 years (IQR = 3.7;10.0)), 6143 (56 %) participants received HCV treatment, 4880 (44 %) were cured, and 1322 participants died (mortality rate = 1.81/100 person-years (PY) [95 % confidence interval (CI)=1.72–1.91]).Overall, PWID had higher mortality rates than MSM (2.5/100 PY [95 % CI = 2.3–2.6] vs. 0.8/100 PY [95 % CI = 0.7–0.9], respectively). Unlike women with other transmission modes, those who injected drugs had a higher mortality hazard than men who did not inject drugs and men who were not MSM (adjusted Hazard-Ratio (aHR) [95 % CI] = 1.3[1.0–1.6]). Post-DAA availability, mortality decreased among MSM in the Netherlands, Spain, and Switzerland and increased among PWID in Canada (aHR [95 % CI] = 1.73 [1.15–2.61]). ConclusionPost-DAA availability, all-cause mortality did not decrease in PWID. Determinants of cause-specific deaths (drug-related, HIV-related, or HCV-related) need to be identified to explain persistently high mortality among PWID in the DAA era.

Trends in socioeconomic inequalities in life expectancy and lifespan variation in Chile.

Socioeconomic disparities in life expectancy are well-documented in various contexts, including Chile. However, there is a lack of research examining trends in life expectancy inequalities and lifespan variation over time. Addressing these gaps can provide crucial insights into the dynamics of health inequalities. This study utilizes data from census records, population surveys, and death certificates to compare the life expectancy and the lifespan variation at age 26 of individuals according to their rank in the distribution of years of education within their own birth cohort. The analysis spans three periods (1991, 2002, and 2017) and focuses on two educational groups: individuals in the first (lowest) quintile and tenth (highest) decile of educational attainment. Changes in life expectancy are disaggregated by major causes of death to elucidate their contributions to overall trends. Consistent with existing literature, our findings confirm that individuals with lower education levels experience lower life expectancy and higher lifespan variation compared to their more educated counterparts. Notably, by 2017, life expectancy for individuals in the lowest quintile of education has caught up with that of the top decile in 1991, albeit with contrasting trends between genders. Among women, the gap has reduced, while it has increased for males. Moreover, lifespan variation decreased (increased) over time for individuals in the tenth decile (first quintile). The leading causes of death that explain the increase in life expectancy in women and men in the tenth decile as well as women in the first quintile are cardiovascular, cancer, respiratory and digestive diseases. In the case of males in the first quintile, few gains have been made in life expectancy resulting from cancer and a negative contribution is associated with digestive conditions. This study underscores persistent socioeconomic disparities in life expectancy in Chile, emphasizing the importance of ongoing monitoring of health inequalities across different demographic segments. The gender-specific and educational gradient trends highlight areas for targeted interventions aimed at reducing health disparities and improving overall population health outcomes. Further research is warranted to delve into specific causes of death driving life expectancy differentials and to inform evidence-based policy interventions.

All-cause and cause-specific mortality by spirometric pattern and sex - a population-based cohort study.

Chronic airway obstruction (CAO) and restrictive spirometry pattern (RSP) are associated with mortality, but sex-specific patterns of all-cause and specific causes of death have hardly been evaluated. To study the possible sex-dependent differences of all-cause mortality and patterns of cause-specific mortality among men and women with CAO and RSP, respectively, to that of normal lung function (NLF). Population-based prospective cohort study. Individuals with CAO [FEV1/vital capacity (VC) < 0.70], RSP [FEV1/VC ⩾ 0.70 and forced vital capacity (FVC) < 80% predicted] and NLF (FEV1/VC ⩾ 0.70 and FVC ⩾ 80% predicted) were identified within the Obstructive Lung Disease in Northern Sweden (OLIN) studies in 2002-2004. Mortality data were collected through April 2016, totally covering 19,000 patient-years. Cox regression and Fine-Gray regression accounting for competing risks were utilized to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) adjusted for age, body mass index, sex, smoking habits and pack-years. The adjusted hazard for all-cause mortality was higher in CAO and RSP than in NLF (HR, 95% CI; 1.69, 1.31-2.02 and 1.24, 1.06-1.71), and the higher hazards were driven by males. CAO had a higher hazard of respiratory and cardiovascular death than NLF (2.68, 1.05-6.82 and 1.40, 1.04-1.90). The hazard of respiratory death was significant in women (3.41, 1.05-11.07) while the hazard of cardiovascular death was significant in men (1.49, 1.01-2.22). In RSP, the higher hazard for respiratory death remained after adjustment (2.68, 1.05-6.82) but not for cardiovascular death (1.11, 0.74-1.66), with a similar pattern in both sexes. The higher hazard for all-cause mortality in CAO and RSP than in NLF was male driven. CAO was associated with respiratory death in women and cardiovascular death in men, while RSP is associated with respiratory death, similarly in both sexes.

Competing risk nomogram predicting cause-specific mortality in older patients with testicular germ cell tumors.

Testicular germ cell tumor (TGCT) is the most common type of malignancy in young men, but rarely in older adults. We aimed to construct a competing risk model to predict the prognosis for older patients with TGCT. We collected TGCT patients aged 50 years or older diagnosed between 2004 and 2015 from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database. We estimated the cumulative incidences of cause-specific death (CSD) and other causes of death and established a nomogram predicting cause-specific mortality in older patients with TGCT by Fine-Gray competing risk regression. The concordance index (C-index), calibration curves, area under the receiver operating characteristic curve (AUC), and decision analysis curves (DCA) were used to evaluate the differentiation, accuracy, and clinical significance of the nomogram. A total of 2,751 older TGCT patients were included in the study. The 3-, 5-, and 10-year cumulative incidences were 4.4, 5.0 and 6.1%, respectively, for cause-specific death, and 3.8, 6.2, 13.1%, respectively, for other causes of death. Predictors of cause-specific mortality in older TGCT included age, marital status, annual household income, histology, tumor size, stage and surgery. In the training and validation sets, the C-indexes were greater than 0.8, indicating that the nomogram had good discrimination. The AUC revealed the same result. The calibration curves showed good agreement between the predicted and observed results of the nomogram. DCA curves indicated that the nomogram had more clinical significance than the conventional American Joint Committee on Cancer (AJCC) staging. Based on the total nomogram score of each case, all patients were categorized into low-risk and high-risk groups, and risk categorization allowed the identification of cases with a high risk of death. We established a competing risk nomogram with good performance that may help clinicians accurately predict the prognosis of older TGCT patients.

Assessment of Neonatal Mortality and Associated Hospital-Related Factors in Healthcare Facilities Within Sunyani and Sunyani West Municipal Assemblies in Bono Region, Ghana.

Ghana's quest to reduce neonatal mortality, in hospital facilities and communities, continues to be a nightmare. The pursuit of achieving healthy lives and well-being for neonates as enshrined in Sustainable Development Goal three lingered in challenging hospital facilities and communities. Notwithstanding that, there have been increasing efforts in that direction. This study examines the contributing factors that hinder the fight against neonatal mortality in all hospital facilities in the Sunyani and Sunyani West Municipal Assemblies in Bono Region, Ghana. The study utilized neonatal mortality data consisting of neonatal deaths, structural facility related variables, medical human resources, types of hospital facilities and natal care. The data was collected longitudinally from 2014 to 2019. These variables were analysed using the negative binomial hurdle regression (NBH) model to determine factors that contribute to this menace at the facility level. Cause-specific deaths were obtained to determine the leading causes of neonatal deaths within health facilities in the two municipal assemblies. The study established that the leading causes of neonatal mortality in these districts are birth asphyxia (46%), premature birth (33%), neonatal sepsis (11%) and neonatal jaundice (7%). The NBH showed that neonatal mortality in hospital facilities depend on the number of incubators, monitoring equipment, hand washing facilities, CPAPb machines, radiant warmers, physiotherapy machines, midwives, paediatric doctors and paediatric nurses in the hospital facility. Early management of neonatal sepsis, birth asphyxia, premature birth and neonatal infections is required to reduce neonatal deaths. The government and all stakeholders in the health sector should provide all hospital facilities with the essential equipment and the medical human resources necessary to eradicate the menace. This will make the realization of Sustainable Development Goal three, which calls for healthy lives and well-being for all, a reality.

Suicide during pregnancy as a major contributor to maternal suicide among female sex workers in eight low- and middle-income countries: A community knowledge approach investigation

Abstract Studies indicate a high burden of mental health disorders among female sex workers (FSWs) in low- and middle-income countries (LMICs). Despite available data on suicidal ideation and suicide attempts among FSWs, little is known about suicide deaths in this hard-to-reach population. This study aims to examine the extent to which suicide is a cause of maternal mortality among FSWs, the contexts in which suicides occur, and the methods used. From January to October 2019, the Community Knowledge Approach method for identifying cause-specific deaths in communities was employed across eight LMICs (Angola, Brazil, the Democratic Republic of the Congo (DRC), India, Indonesia, Kenya, Nigeria, and South Africa). A total of one thousand two hundred eighty FSWs provided detailed reports on two thousand one hundred twelve FSW deaths in the preceding 5 years, including 288 (13.6%) suicides, 178 (61.8%) of which were maternal. Of these maternal suicides, 57.9% occurred during pregnancy (antepartum), 20.2% within two months of delivery (puerperium), and 21.9% in the 2–12 months following delivery (postpartum). The highest proportion of suicides occurred in Nigeria, Kenya, and DRC in sub-Saharan Africa. A total of 504 children lost their mothers to suicide. Further research is needed to identify interventions for suicide risk among FSW mothers.

Severe depression and all-cause and cause-specific mortality in Scotland: 20 year national cohort study.

Understanding cause of death in people with depression could inform approaches to reducing premature mortality. To describe all-cause and cause-specific mortality for people with severe depression in Scotland, by sex, relative to the general population. We performed a retrospective cohort study, using psychiatric hospital admission data linked to death data, to identify adults (≥18 years old) with severe depression and ascertain cause-specific deaths, during 2000-2019. We estimated relative all-cause and cause-specific mortality for people with severe depression using standardised mortality ratios (SMRs), stratified by sex using the whole Scottish population as the standard. Of 28 808 people with severe depression, 7903 (27.4%) died during a median follow-up of 8.7 years. All-cause relative mortality was over three times higher than expected (SMR, both sexes combined: 3.26, 95% CI 3.19-3.34). Circulatory disease was the leading cause of death, and, among natural causes of death, excess relative mortality was highest for circulatory diseases (SMR 2.51, 2.40-2.66), respiratory diseases (SMR 3.79, 3.56-4.01) and 'other' causes (SMR 4.10, 3.89-4.30). Among circulatory disease subtypes, excess death was highest for cerebrovascular disease. Both males and females with severe depression had higher all-cause and cause-specific mortality than the general population. Suicide had the highest SMR among both males (SMR 12.44, 95% CI 11.33-13.54) and females (22.86, 95% CI 20.35-25.36). People with severe depression have markedly higher all-cause mortality than the general population in Scotland, with relative mortality varying by cause of death. Effective interventions are needed to reduce premature mortality for people with severe depression.
