Domestic violence perpetration, victimisation and self-poisoning in Sri Lanka: a protocol for a hospital-based case-control study

Introduction
Domestic violence is a key risk factor for suicidal behaviour. While there is some evidence on the association between suicide and victimisation, there is a notable paucity of evidence pertaining to the perpetration of domestic violence and its association with suicidal behaviour. The aim of this study is to investigate the association between domestic violence (victimisation and perpetration) and self-poisoning in Sri Lanka.

Methods and analysis
This is a hospital-based case-control study. Cases (n=260) will be individuals admitted to the toxicology ward of the Teaching Hospital Peradeniya, Sri Lanka, for medical management of self-poisoning. We will recruit controls (n=520) from other patients with unrelated conditions or accompanying visitors presenting to the outpatient department of Teaching Hospital Peradeniya. We will use unconditional logistic regression models to investigate the association between domestic violence and self-poisoning.

Ethics and dissemination
We obtained ethics approval from the Ethical Review Committee of the Faculty of Medicine, University of Peradeniya, Sri Lanka. The research assistants will be trained in administering the questionnaire and ensuring participant safety. Results will be disseminated in peer-reviewed articles, local media and at national and international conferences.

Outcomes of Transcatheter Aortic Valve Replacement in Low-Risk Patients in the United States: A Report From the STS/ACC TVT Registry

Circulation, Ahead of Print. BACKGROUND:Real-world low-risk transcatheter aortic valve replacement (TAVR) outcomes in the United States have not been assessed comprehensively versus pivotal trials, which is a key component of measuring the quality of clinical technology adoption.METHODS:We identified heart team–designated low-risk patients undergoing TAVR for trileaflet severe, symptomatic aortic stenosis in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Registry, as well as a subset of patients who met low-risk trial inclusion and exclusion criteria, from January 2020 to March 2024. Outcomes (mortality, stroke, new pacemaker, and “alive and well,” defined as alive at 1 year with Kansas City Cardiomyopathy Questionnaire score ≥60 and ≤10-point decrease from baseline) at 30 days and 1 year were assessed. Multivariable models were developed to assess predictors of death within 1 year after TAVR.RESULTS:Among 383 030 patients who underwent TAVR during the study period, 108 407 (28%) were designated low risk by the heart team, and 68 194 (18%) met other study inclusion and exclusion criteria. Of these, 62% (n=42 093) would have been eligible for the low-risk trials. In the overall heart team–designated low-risk population, 30-day outcomes included 0.8% mortality, 1.5% stroke, and 8.4% new permanent pacemaker requirement; 1-year outcomes included 4.6% mortality, 2.6% stroke, and 90% alive and well. In the trial-eligible population, 0.6% mortality, 1.4% stroke, and 8.0% new permanent pacemaker requirement had occurred by 30 days; values at 1 year included 3.1% mortality, 2.4% stroke, and 92% alive and well. Notable multivariable predictors of 1-year mortality were atrial fibrillation, nontransfemoral access, and lower baseline Kansas City Cardiomyopathy Questionnaire score.CONCLUSIONS:One-year outcomes among real-world trial-eligible patients are excellent, but adverse events are higher compared with published clinical trial data, likely because of greater comorbidity burden and lower baseline Kansas City Cardiomyopathy Questionnaire score. These data can help inform expected outcomes and health status after low-risk TAVR.

Association of occupational physical activity and sedentary behaviour with the risk of hepatocellular carcinoma: a case-control study based on the Inpatient Clinico-Occupational Database of Rosai Hospital Group

Objectives
While there is growing evidence that physical activity reduces the risk of hepatocellular carcinoma (HCC), the impact of occupational physical activity and sedentary behaviour remains unclear. This study aimed to investigate the associations between occupational physical activity and sedentary behaviour and HCC risk.

Design
Matched case-control study.

Setting
Nationwide multicentre, hospital-inpatient data set in Japan, from 2005 to 2021.

Participants
The study included 5625 inpatients diagnosed with HCC and 27 792 matched controls without liver disease or neoplasms. Participants were matched based on sex, age, admission date, and hospital.

Primary measures
The association between levels of occupational physical activity (low, medium, high) and sedentary time (short, medium, long) with the risk of HCC.

Secondary measures
Stratification of HCC risk by viral infection status (hepatitis B/C virus), alcohol consumption levels and the presence of metabolic diseases (hypertension, diabetes, dyslipidaemia, obesity).

Results
High occupational physical activity was not associated with HCC caused by hepatitis B/C virus infection in men. In women, high occupational physical activity was associated with a reduced risk of non-viral HCC, with ORs (95% CIs) of 0.65 (0.45–0.93). Among patients with non-viral HCC, medium occupational physical activity combined with medium alcohol intake further decreased the HCC risk in men with an OR of 0.70 (0.50–0.97), while high occupational physical activity combined with lowest alcohol intake decreased the HCC risk in women with an OR of 0.69 (0.48–0.99). Men and women with medium sedentary time had a lower HCC risk compared with those with long sedentary time, with ORs of 0.88 (0.79–0.98) in men and 0.77 (0.62–0.97) in women, respectively. In patients without viral infection or alcohol use, medium sedentary time reduced the HCC risk associated with fatty liver disease without comorbid metabolic diseases in women.

Conclusions
High levels of occupational physical activity and/or medium periods of sedentary time are associated with a reduced risk of HCC, particularly non-alcoholic steatohepatitis.
