Article Abstract

Background: Current reporting and statistical adjustment practices of studies based on The Society of Thoracic Surgeons Adult Cardiac Surgery Database (STS ACSD) have not been described.

Methods: A review identified all published studies based on STS ACSD data from January 2016 to May 2024. Data were extracted by 2 authors and independently checked by the senior author.

Results: A total of 134 studies were included. There were 46 (34.3%) studies on coronary artery bypass grafting, 22 (16.4%) on mitral valve surgery, 16 (11.9%) on aortic surgery, 14 (10.4%) on surgical aortic valve replacement, 3 (2.2%) on tricuspid valve surgery, 18 (13.4%) on combined procedures, and 15 (11.2%) on other interventions; 59 (44.0%) studies used the Participant User File (PUF) program, with a significant increase over time (P = .005). Of the 1239 variables available in the STS ACSD (version 4.20.2), 136 (11.0%; median, 21 variables per study; interquartile range [IQR], 16-25) were used to describe the baseline characteristics of the patients and 191 (15.4%; median, 22 variables per study; IQR, 17-33) for statistical adjustment; 121 studies (90.3%) performed statistical adjustment, with multivariable regression used in most (80 [66.1%]). PUF manuscripts had significantly more junior first authors (20.3% vs 1.3%; P = .001) and were published in higher impact journals (median impact factor, 4.90 [IQR, 3.70-9.15] vs 3.90 [IQR, 3.60-4.70]; P = .002) compared with non-PUF manuscripts.

Conclusions: Our analysis provides data that may inform efforts to standardize reporting and analytic practices in studies based on the STS ACSD.

Background: Mental health problems are common in the working-age population. More knowledge is needed on how to support work participation and reduce sickness absence. The objective of the study was to estimate the distribution of mental well-being and work capacity in women and men in a working population and assess the association between mental well-being and work capacity, while adjusting for sociodemographic characteristics, health status, and working positions.

Background: As populations age, more knowledge is needed on people who extend their working lives. The aim of this study was to explore if prior sickness absence (> 14 days) and/or disability pension (SADP) in mental and/or somatic diagnoses were associated with time until work exit after ages 65-69 and ≥ 70, respectively, among women and men.

Methods: This prospective population-based cohort study included all 65-69-year-olds (cohort65, n = 201,263) and ≥ 70-year-olds (cohort70, n = 93,751) who were in paid work in Sweden in 2014.

We study the dynamics of coexisting influenza and SARS-CoV-2 by adapting a well-established age-specific COVID-19 model to a multi-pathogen framework. Sensitivity analysis and adjustment of the model to real-world data are used to investigate the influence of age-related factors on disease dynamics. Our findings underscore the critical role that transmission rates play in shaping the spread of influenza and COVID-19.

Background: Maternal healthcare (MHC) in Cameroon reflects the persistent challenges in Sub-Saharan Africa, where high maternal mortality continues despite improved service utilization, stressing inequitable effective coverage (EC). This study applied EC cascade analysis-including service contact, continuity, and input-adjusted coverage-to quantify geographic and socioeconomic disparities, informing equity-focused strategies to dismantle structural barriers in the MHC continuum.

Methods: We combined population and health facility data (2018 Cameroon Demographic and Health Survey and 2015 Emergency Obstetric and Neonatal Care Assessment) to estimate the input-adjusted coverage of antenatal care (ANC) and intra-and postpartum care (IPC).

Background And Aims: Obesity-related non-alcoholic fatty liver disease (NAFLD) and serum high-sensitivity C-reactive protein (hs-CRP) are known to be associated to some extent. Nevertheless, this relationship remains unclear in non-obese individuals.

Methods And Results: A prospective cohort study was conducted using data from the health check ups of employees at Zhenhai Refining and Chemical Hospital in Ningbo City.
