Background: Reduced cardiovascular event risk is observed with eicosapentaenoic acid (EPA), but EPA mixed with docosahexaenoic acid (EPA/DHA) does not show consistent benefit. Comparative effects of EPA versus EPA/DHA on coronary plaque remain unclear.

Methods: We systematically reviewed trials measuring coronary plaque volume in patients randomised to statin + EPA or statin + EPA/DHA therapy compared to statin monotherapy, and used network meta-analysis to compare percent change in total and lipid coronary plaque volumes on these treatments.

Background: Haemolytic uraemic syndrome (HUS) is a common cause of acquired kidney failure in children and rarely in adults. The most important risk factor for the development of HUS is a gastrointestinal infection by Shiga toxin-producing Escherichia coli (STEC). This is an update of the Cochrane review published in 2021 and addresses the interventions aimed at secondary prevention of HUS in patients with diarrhoea who are infected with bacteria that increase the risk of HUS.

Background: Prior international collaborative studies indicated that job satisfaction, a factor of nursing work wellbeing (WWB), is closely linked to retention, with notable cross-country differences. However, limited regional comparisons, especially between Central and Eastern Europe (CEE), North America, and the Middle East and North Africa (MENA), restrict understanding of nurse wellbeing and retention regional impacts, limiting tailored strategy development.

Aims: This secondary analysis study compared the effects of region on nursing WWB and job satisfaction factors in CEE, MENA, and North America, aiming to identify those CEE region-specific predictors associated with and effects on job satisfaction and, in turn, WWB.

Background: This 2022-2023 study across nine countries builds on a 2019-2021 ten-country study exploring nurse work well-being (WWB) and its associated outcomes. WWB, as assessed using the Profile of Caring (PoC) survey, is conceptualized as a multifactorial construct encompassing caring for self, caring of manager, clarity of role/system, and job satisfaction.

Aims: To explore relationships between WWB and staff outcomes by evaluating the PoC construct validity within an international nursing population in the post-pandemic context.

Introduction: Icosapent ethyl (IPE) is indicated for the treatment of severe hypertriglyceridemia (triglycerides ≥500 mg/dl) and for reducing the risk of cardiovascular (CV) events in statin-treated adults with moderately elevated triglycerides (150-499 mg/dl) and established CV disease [secondary prevention (SP)] or diabetes with CV risk factors [primary prevention (PP)]. We describe real-world characteristics of US patients taking IPE.

Methods: Patients with ≥2 IPE prescriptions were identified in the TriNetX database.

Background: The REDUCE-IT trial demonstrated significant reductions in cardiovascular events with icosapent ethyl (IPE) treatment among patients with elevated triglyceride levels; however, patients on IPE experienced slightly more atrial fibrillation/flutter, bleeding, constipation, and peripheral edema events compared with patients receiving placebo. The real-world frequency of these events outside of trials and spontaneous postmarketing reports is unknown.

Sources Of Material: The frequency of the events of interest with IPE was compared across the REDUCE-IT trial, product labels, and real-world evidence (RWE) estimates derived using the MarketScan Commercial Claims database.

Background: Percutaneous coronary intervention (PCI) is considered the procedure of choice for patients with acute coronary syndrome (ACS), as it significantly improves cardiovascular outcomes. However, considerable uncertainty persists regarding the potential sex differences in PCI outcomes, due to conflicting results in previous studies.

Objectives: This meta-analysis aims to evaluate potential sex-related differences in cardiovascular adverse outcomes after PCI among ACS patients.

Introduction: The US state of Florida has the third highest rate of HIV and high rates of sexually transmitted infections (STIs) indicating critical HIV and STI prevention needs remain unmet. To address gaps in the STI care continuum in people with HIV (PWH), evidence-based interventions were implemented across 3 Ryan White HIV/AIDS Program (RWHAP)-funded clinics in Florida between August 2020 and August 2021. Interventions included comprehensive sexual health history (SHH) taking using audio computer-assisted self-interview (ACASI) software, self-collected extragenital gonorrhea and chlamydia testing, and the introduction of a lesbian, gay, bisexual, transgender, and queer (LGBTQ+) welcoming environment.

Article Synopsis
  • The study investigates the role of CCND1 gene amplification in the prognosis of hormone receptor-positive breast cancer patients, particularly in the context of resistance to endocrine therapy.
  • A cohort of 894 breast cancer patients was analyzed, revealing that 12.9% had CCND1 amplification, predominantly in luminal B-like and HER2-positive tumor types.
  • The findings indicate that while CCND1 amplification is common in certain breast cancer subtypes, it does not show significant differences in disease-free survival or overall survival among HR-positive, HER2-negative patients.

Historically, cisgender men have been found to be reluctant to utilize healthcare services, particularly preventive care services. NPs can bridge this gap to address health disparities among men, who are more likely to develop life-threatening conditions and who generally face higher mortality at younger ages than women. Focusing on advancing preventive care among men strengthens family, community, and societal health, and the NP is crucial in fostering a culture of preventive care in this population.

Article Synopsis
  • The Triglyceride-glucose index (TyG) serves as a marker for insulin resistance and may predict the risk of major adverse cardiac and cerebrovascular events (MACCE) in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI).
  • A study involving 13,542 patients showed that higher TyG levels, particularly in the fourth quartile, significantly correlated with an increased risk of MACCE, such as heart attacks and strokes.
  • In contrast, no significant association was found between TyG levels and MACCE in a subgroup of patients who were euglycemic, suggesting the need for further studies to confirm these findings for better clinical risk assessment.
