Enhancing quality of life and functional capacity in heart failure patients with iron deficiency: A regional cross-sectional study on intravenous iron therapy in Vietnam.

Intravenous iron supplementation, particularly ferric carboxymaltose (FCM), has emerged as an effective therapeutic strategy for correcting iron deficiency (ID) in patients with heart failure with reduced ejection fraction (HFrEF). However, the enhancement related to the quality of life (QoL) and functional capacity remains unclear, specifically in the Vietnam population. This study assesses the enhancement of QoL and functional capacity in intravenous FCM therapy in heart failure patients with ID.

Uranyl ammonium carbonate precipitation and conversion into triuranium octaoxide.

Uranyl ammonium carbonate (AUC), with the chemical formula UOCO·2(NH)CO, plays a crucial role in the wet conversion of uranium hexafluoride (UF) into uranium dioxide (UO) or triuranium octaoxide (UO) for nuclear fuel production, and is used in commercial and research reactors. In this study, the precipitation of AUC from uranyl fluoride (UOF) solution and its subsequent conversion into UO powder were investigated. AUC precipitation was performed at uranium concentrations in UOF solution of 80-120 gL, ammonium carbonate (NH)CO concentrations of 200-400 gL, and (NH)CO to U (C/U) ratios of 5-9.

The effect of plaque morphology, material composition and microcalcifications on the risk of cap rupture: A structural analysis of vulnerable atherosclerotic plaques.

Background: The mechanical rupture of an atheroma cap may initiate a thrombus formation, followed by an acute coronary event and death. Several morphology and tissue composition factors have been identified to play a role on the mechanical stability of an atheroma, including cap thickness, lipid core stiffness, remodeling index, and blood pressure. More recently, the presence of microcalcifications (μCalcs) in the atheroma cap has been demonstrated, but their combined effect with other vulnerability factors has not been fully investigated.

Pattern of SARS-CoV-2 infection among dependant elderly residents living in long-term care facilities in Marseille, France, March-June 2020.

Objectives: This study aimed to report the results of SARS-CoV-2 PCR-based screening campaigns conducted on dependent elderly residents (compared with staff members) in long-term care facilities (LTCFs) in Marseille, France, and the follow-up of positive cases.

Methods: Data from 1691 elderly residents and 1000 members of staff were retrospectively collected through interviewing the medical teams in 24 LTCFs and using the hospitals' electronic health recording systems.

Results: Elderly residents were predominantly female (64.
