Long-term pulse pressure trajectories and risk of incident atrial fibrillation: the Tromsø Study.

Background And Aims: Sex-based differences in the association of long-term trends in pulse pressure with future risk of atrial fibrillation (AF) have been explored using data from the population-based Tromsø Study 1986-2016.

Methods: Women (n = 8331) and men (n = 7638) aged ≥20 years who attended at least two of the three Tromsø Study surveys conducted between 1986 and 2001 (the exposure period) were followed up for incident AF throughout 2016 (the follow-up period). Pulse pressure ≥60 mmHg was considered elevated.

'Entanglement of nursing care': A theoretical proposition to understand the complexity of nursing work and division of labour.

Ongoing challenges in the provision of care, driven by growing care complexity and nursing shortages, prompt us to reconsider the basis for efficient division of nursing labour. In organising nursing work, traditionally the focus has been on identifying nursing tasks that can be delegated to other less expensive and less highly educated staff, in order to make best use of scarce resources. We argue that nursing care activities are connected and intertwined.

The Limited Utility of Hemoglobin A1c as a Predictor for Periprosthetic Joint Infection Following Total Joint Arthroplasty: A Continuous Variable Analysis.

Introduction: Patients who have poorly controlled diabetes mellitus are at increased risk of periprosthetic joint infection (PJI). Nevertheless, an optimal preoperative hemoglobin A1c (HbA1c) threshold has not been established. This study sought to identify preoperative HbA1c thresholds that were predictive of adverse outcomes for total hip (THA) and total knee arthroplasty (TKA) patients.

National Trends in Lumbar Degenerative Spondylolisthesis With Stenosis Treated With Fusion Versus Decompression.

Objective: The purpose of this study is to describe utilization, demographics, complications, and revisions for patients with degenerative spondylolisthesis (DS) with stenosis undergoing decompression or decompression with fusion in the United States.

Methods: A national insurance database was used to identify patients who underwent either decompression and fusion or decompression alone for management of DS from 2010-2022. Utilization trends, demographics, and complications for each procedure were compared.

Steering perovskite precursor solutions for multijunction photovoltaics.

Multijunction photovoltaics (PVs) are gaining prominence owing to their superior capability of achieving power conversion efficiencies (PCEs) beyond the radiative limit of single-junction cells, where improving narrow bandgap tin-lead perovskites is critical for thin-film devices. With a focus on understanding the chemistry of tin-lead perovskite precursor solutions, we herein find that Sn(II) species dominate interactions with precursors and additives and uncover the exclusive role of carboxylic acid in regulating solution colloidal properties and film crystallisation, and ammonium in improving film optoelectronic properties. Materials that combine these two function groups, amino acid salts, considerably improve the semiconducting quality and homogeneity of perovskite films, surpassing the effect of the individual functional groups when introduced as part of separate molecules.
