Circulation, Ahead of Print. Background:Guidelines have suggested screening for atrial fibrillation to enable early treatment and avoid downstream negative clinical events. We aimed to determine if atrial fibrillation screening potentially enhanced by NT-proBNP would reduce stroke or systemic embolism incidence as compared to in a control group and to determine if it was safe for those with low NT-proBNP concentrations to forfeit prolonged screening.Methods:In this randomized controlled trial all 75/76-year-old individuals in Stockholm Region, Sweden were randomized 1:1 to be invited to screening or serve as a control group. NT-proBNP concentration were measured and a single-lead-ECG registered only once if NT-proBNP

This cohort study examines the use of routine electrocardiogram (ECG) screening in identifying individuals at risk for cardiovascular disease.

In their article on routine electrocardiogram (ECG) screening and cardiovascular disease (CVD) events Yagi and colleagues report findings from a nationwide cohort study on screening electrocardiography in Japan between January 2015 and December 2021. Since 1989, an annual screening ECG has been mandatory for working-age people in Japan aged 35 years and older. The authors assessed claims and annual health screening data from the Japan Health Insurance Association that included 3 698 429 individuals registered in the database and who had a screening ECG in 2016. Electrocardiograms were classified as having 1 minor abnormality, 2 or more minor abnormalities, or major abnormalities. Using multivariable Cox proportional hazards models and adjusting for multiple clinical covariates, the authors found a greater risk of the composite outcome of overall death or hospital admission for CVD in people with 1 minor abnormality (hazard ratio [HR], 1.19; 95% CI, 1.18-1.20), 2 or more minor abnormalities (HR, 1.37; 95% CI, 1.34-1.39), and major ECG abnormalities (HR, 1.96; 95% CI, 1.92-2.02) compared with people with a normal ECG result. Cardiovascular events were observed across subgroups by age, sex, and low vs moderate to high CVD risk groups. The authors concluded that “further studies are needed to elucidate the role of routine ECG screening for early prevention of CVD events, along with optimal follow-up strategies for both major and minor ECG abnormalities.”

Background
Occupational diseases are one of the most important health problems related to employment However, in Malaysia, there are few epidemiological studies discussing these issues, especially among workers in the industry. For that, this study aimed to screen workers from high-risk industrial sectors, identify hazards in the workplace and recommend improvement measures in the workplace to prevent occupational diseases.

Methods and analysis
This is a 3-year project in which a survey of 100 000 workers from all 13 states in Malaysia will be conducted using a web-based screening tool that is comprised of two parts: occupational disease screening tool and hazard identification, risk assessment and risk control method. Data will be collected using a multistage stratified sampling method from 500 companies, including seven critical industrial sectors. The independent variables will be sociodemographic characteristics, comorbidities, previous medical history, high-risk behaviour and workplace profile. The dependent variable will be the types of occupational diseases (noise-induced hearing loss, respiratory, musculoskeletal, neurotoxic, skin and mental disorders). Subsequently, suggestions of referral for medium and high-risk workers to occupational health clinics will be attained. The approved occupational health service clinics/providers will make a confirmatory diagnosis of each case as deemed necessary. Subsequently, a walk-through survey to identify workplace hazards and recommend workplace improvement measures to prevent these occupational diseases will be achieved. Both descriptive and inferential statistics will be used in this study. Simple and adjusted binary regression will be used to find the determinants of occupational diseases.

Ethics and dissemination
This study has been approved by the MARA University of Technology Research Ethics Board. Informed, written consent will be obtained from all study participants. Findings will be disseminated to the Department of Occupational Health and Safety, involved industries, and through peer-reviewed publications.

Con lo screening intermittente +10% diagnosi di cancro avanzato

In April 2024, the US Preventive Services Task Force (USPSTF) recommended that women aged 40 to 74 years with an average risk of breast cancer undergo mammography screening every 2 years. This updated the USPSTF’s prior suggestion that women aged 40 to 49 years engage in shared decision-making with their clinician before deciding whether to be screened.

Objectives
Investigating men’s perceived lifetime risk of prostate cancer.

Design
Survey-based study to men invited for prostate-specific antigen (PSA) screening in the GÖTEBORG-2 trial between September 2015 and June 2020.

Setting
38 775 men in the Gothenburg area, Sweden, were invited for PSA-testing and participated in a survey.

Participants
17 980 men participated in PSA-testing, of whom 13 189 completed the survey. In addition, 1264 men answered the survey only.

Interventions
Before having the PSA-test, men answered an electronic survey and estimated their lifetime risk of receiving a prostate cancer diagnosis on a visual analogue scale from 0% to 100%.

Main outcome measures
The primary outcome was the median lifetime risk estimation, which was compared with Wilcoxon test to an anticipated lifetime risk of 20% (based on GÖTEBORG-1 trial). The secondary outcome was to determine factors associated with risk estimation in a multivariable linear regression model: previous prostate examination, family history, physical exercise, healthy diet, comorbidity, alcohol consumption, smoking, education level, marital status, urinary symptoms and erectile dysfunction.

Results
Among PSA-tested men, the median estimated lifetime risk of prostate cancer was 30% (IQR 19% to 50%), corresponding to a 10 percentage-points higher estimation compared with the anticipated risk (p5 percentage-points higher risk estimation. Similar results were obtained for non-PSA-tested men.

Conclusions
Most men overestimated their prostate cancer risk which underscores the importance of providing them accurate information about prostate cancer.

Objectives
The main aim was to determine the diagnostic performance of an albuminuria point-of-care test (POC) for diagnosis of chronic kidney disease among young people living with HIV (YPLHIV) in Uganda.

Design
We conducted a cross-sectional study comparing the diagnostic performance of MicroalbuPHAN (Erba Lachema, Czech Republic), an albuminuria POC test against the laboratory-measured albumin and creatinine as the reference standard.

Setting
The study was set in seven HIV clinics in Kampala, Uganda that provide antiretroviral therapy to adults and children living with HIV. The study took place from April to August 2023.

Participants
497 YPLHIV aged 10–24 years who were diagnosed with HIV before 10 years of age were randomly selected from the HIV clinics. Pregnant YPLHIV were excluded.

Procedures
Participants provided a spot urine sample that was tested for albumin and creatinine using the POC and in the laboratory and proteinuria using urine dipstick. The sensitivity, specificity, negative and positive predictive values (NPV, PPV) of the POC versus the laboratory test were calculated, and factors associated with having a positive POC test were estimated using logistic regression.

Outcome measures
The primary outcome was a diagnosis of albuminuria defined as an albumin creatinine ratio above 30 mg/g.

Results
Of the 497 participants enrolled, 278 (55.9%) were female and 331 (66.8%) were aged 10–17 years. The POC test had a sensitivity of 74.5% (95% CI 70.6% to 78.4%) and specificity of 68.1% (95% CI 63.9% to 72.3%). The PPV was 21.5% (95% CI 17.8% to 25.1%) and the NPV was 95.8% (95% CI 94.0% to 97.6%), with an accuracy of 68.8%. There was strong evidence that a positive POC test was associated with having proteinuria (OR 2.82; 95% CI 1.89 to 4.22, p
