Objective: Our objective was to assess the incidence of major adverse cardiovascular events (MACEs) in patients with rheumatoid arthritis (RA) treated with JAK inhibitors (JAKi), tumor necrosis factor inhibitors (TNFi), or biologic disease-modifying antirheumatic drugs with other modes of action (bDMARD-OMA) in a multicountry, real-world population.

Methods: Patients with RA from 15 registries in the JAK-pot collaboration were included. MACE incidence was analyzed using two approaches: a within-registry analysis aggregating country-specific estimates from registers with >25 incident MACEs through meta-analysis and an individual-level data combined analysis.

Objectives: We propose and test a framework to detect disease diagnosis using a recent large language model (LLM), Meta's Llama-3-8B, on French-language electronic health record (EHR) documents. Specifically, it focuses on detecting gout ('goutte' in French), a ubiquitous French term that has multiple meanings beyond the disease. The study compares the performance of the LLM-based framework with traditional natural language processing techniques and tests its dependence on the parameter used.

Article Synopsis
  • The study aimed to see if adding oral glucocorticoids to immunosuppressive therapy improves skin conditions and safety in patients with early diffuse cutaneous systemic sclerosis (dcSSc).
  • It compared two groups: one receiving glucocorticoids combined with immunosuppression, and the other receiving only immunosuppression, assessing changes in the modified Rodnan skin score (mRSS) over about a year.
  • Results showed no significant difference in skin score improvement between the groups, indicating that low-dose glucocorticoids didn't provide added benefits for skin fibrosis nor raised the risk of scleroderma renal crisis.

Objectives: Transparent trial conduct requires prospective registration of a randomized controlled clinical trial (RCT) before the enrollment of the first participant. We aimed to (1) estimate the proportion of RCTs that are prospectively registered and analyze the time trends and factors linked to registration timing and (2) assess the reasons for nonadherence to prospective registration and explore ways to improve compliance. We studied trials published in rheumatology as a case study.

Aims Of The Study: Health equity is a key component of quality of care and an objective for a growing number of quality improvement projects for deontological, ethical, public health and economic reasons. To monitor equity in the delivery of health services in Switzerland, there is a need to implement valid, measurable and actionable equity indicators, along with vulnerability stratifiers such as migrant status, which could lead to differences in quality of care. The aim of this study was to develop a set of healthcare equity indicators and stratifiers targeting inpatient and outpatient populations and to test their feasibility.

  • The study aims to investigate how organized mammography screening programs affect breast cancer screening participation across different socioeconomic groups in Switzerland, which has a diverse linguistic context.
  • Data from 14,173 women was analyzed using various socioeconomic indicators, and Poisson regression was employed to assess the effectiveness of these screening programs.
  • Results showed that while screening programs increased participation significantly, they did not address socioeconomic inequalities in all regions, highlighting the need for public health agencies to tailor initiatives to respect cultural differences and improve equity.

Objective: To develop an automatic gout register from electronic health records (EHRs) data.

Methods: We analysed the EHR of all patients >18 years old from a tertiary academic hospital (2013-2022) based on six criteria: International Classification of Diseases 10 gout diagnosis, urate-lowering therapy prescription, monosodium urate crystals in joint aspiration and gout-related terms in problem lists, clinical or imaging reports. We assessed the positive and negative predictive value (PPV and NPV) of the query by chart reviews.

Objectives: This observational study compares the effectiveness of baricitinib (BARI), a targeted synthetic disease-modifying antirheumatic drug (tsDMARD), with alternative biological DMARDs (bDMARDs) in patients with rheumatoid arthritis (RA), from a prospective, longitudinal cohort.

Methods: We compared patients initiating a treatment course (TC) of BARI, tumour necrosis factor inhibitors (TNFi) or bDMARDs with other modes of action (OMA), during a period when all these DMARDs were available in Switzerland. The primary outcome was drug maintenance; secondary outcomes included discontinuation rates related specifically to ineffectiveness and adverse events.

Objectives: Previous literature has primarily viewed physical effort as an aversive experience. However, recent research suggests that effort can also be valued positively. These differences in approach and avoidance tendencies toward physical effort may play a key role in the self-regulation of physical activity behaviors.

Article Synopsis
  • Cutaneous lupus erythematosus (CLE) can occur on its own or alongside systemic lupus erythematosus (SLE), where lab tests show specific abnormalities.
  • This study aimed to compare isolated CLE to CLE with lab-confirmed SLE and to validate a scoring system predicting the risk of developing severe SLE (sSLE).
  • Results indicated that patients with CLE and laboratory SLE had a significantly higher risk of progressing to sSLE compared to those with isolated CLE, though the study had limitations due to its small, single-center patient sample.

Article Synopsis
  • In a clinical trial, patients with rheumatoid arthritis using the Janus kinase inhibitor tofacitinib experienced higher rates of adverse events compared to those on TNF inhibitors like adalimumab or etanercept.
  • A study aimed to analyze treatment discontinuations due to adverse events among JAK inhibitors, TNF inhibitors, and other biological therapies in a real-world setting involving over 46,000 treatment courses.
  • Results indicated that the rate of treatment discontinuation was similar for TNF inhibitors and JAK inhibitors overall, but certain JAK inhibitors showed different patterns, especially with older patients and specific cardiovascular risk factors, warranting cautious interpretation of the findings.

The current study investigates the prevalence of illegitimate tasks in a hospital setting and their association with patient safety culture outcomes, which has not been previously investigated. We conducted a cross-sectional survey in a tertiary referral hospital. Patient safety culture outcomes were measured using the Hospital Survey on Patient Safety Culture questionnaire; the primary outcome measures were a low safety rating for the respondent's unit and whether the respondent had completed one or more safety event reports in the last 12 months.

The immunity conferred by SARS-CoV-2 vaccines and infections reduces the transmission of the virus. To answer how the effect of immunity is shared between a reduction of infectiousness and an increased protection against infection, we examined >50,000 positive cases and >110,000 contacts from Geneva, Switzerland (June 2020 to March 2022). We assessed the association between secondary attack rate (i.

(1) Background: France implemented a COVID-19 certificate in July 2021 to incentivize the population to uptake COVID-19 vaccines. However, little is known about the variation in its impact across age groups and its dependence on socio-demographic, economic, logistic, or political factors. (2) Methods: Using France's weekly first dose vaccination rate, a counterfactual trend approach allowed for the estimation of the vaccination rate across age groups at a small geographical level before and after the implementation of the health pass.

Background: Interstitial lung diseases (ILD), such as idiopathic pulmonary fibrosis (IPF) and non-specific interstitial pneumonia (NSIP), and chronic obstructive pulmonary disease (COPD) are severe, progressive pulmonary disorders with a poor prognosis. Prompt and accurate diagnosis is important to enable patients to receive appropriate care at the earliest possible stage to delay disease progression and prolong survival. Artificial intelligence-assisted lung auscultation and ultrasound (LUS) could constitute an alternative to conventional, subjective, operator-related methods for the accurate and earlier diagnosis of these diseases.

Binding antibody levels against SARS-CoV-2 have shown to be correlates of protection against infection with pre-Omicron lineages. This has been challenged by the emergence of immune-evasive variants, notably the Omicron sublineages, in an evolving immune landscape with high levels of cumulative incidence and vaccination coverage. This in turn limits the use of widely available commercial high-throughput methods to quantify binding antibodies as a tool to monitor protection at the population-level.
