Drivers of vaccine hesitancy among vulnerable populations in India: a cross-sectional multi-state study.

Objectives: India's Covid-19 vaccination campaign engaged frontline workers (FLWs) to encourage vaccination among vulnerable segments of society. The FLWs report encountering a variety of barriers to vaccination and are often unsuccessful despite multiple visits to the same person. This cross-sectional study aims to pinpoint which of these barriers drive vaccine hesitancy among these segments, to help streamline vaccine communication, including FLW training, to better safeguard the population.

Characterization and referral patterns of ST-elevation myocardial infarction patients admitted to chest pain units rather than directly to catherization laboratories. Data from the German Chest Pain Unit Registry.

Background: Direct transfer to the catheterization laboratory for primary percutaneous coronary intervention (PCI) is standard of care for patients with ST-segment elevation myocardial infarction (STEMI). Nevertheless, a significant number of STEMI-patients are initially treated in chest pain units (CPUs) of admitting hospitals. Thus, it is important to characterize these patients and to define why an important deviation from recommended clinical pathways occurs and in particular to quantify the impact of deviation on critical time intervals.

Admission heart rate in relation to presentation and prognosis in patients with acute myocardial infarction. Treatment regimens in German chest pain units.

Background: Higher heart rates on admission have been associated with poor outcomes in patients with an acute coronary syndrome in previous cohorts. Whether such a linear relationship still exists in contemporary high-level care is unclear.

Methods: Prospectively collected data from patients presenting with myocardial infarction (MI) in centers participating in the Chest Pain Unit (CPU) Registry between December 2008 and July 2014 were analyzed.

Predictors of outcome in patients with parvovirus B19 positive endomyocardial biopsy.

Objective: Primary objective was to establish the prognostic value of the myocardial load of PVB19 genomes in patients presenting for work-up of myocarditis and/or unclear cardiomyopathy in comparison to clinical, and CMR parameters.

Methods: 108 consecutive patients who underwent EMB because of suspected myocarditis and/or unclear cardiomyopathy, and had evidence of myocardial PVB19 genome, were enrolled. Primary endpoint was all-cause mortality; secondary endpoint was a composite of cardiac mortality and hospitalization for heart failure.
