Cost burden of productivity loss due to sickness presenteeism among nurses in South Korea: A cross-sectional study.

Aim: This study aimed to estimate the annual cost burden of productivity loss due to sickness presenteeism among hospital nurses in South Korea.

Background: Despite nurses being potentially more vulnerable to presenteeism, few studies have analyzed nurses' productivity losses due to sickness presenteeism.

Methods: This cross-sectional study employed an online survey in January 2023 with 607 nurses working in general/tertiary hospitals in South Korea.

Predictors and prognosis of elderly hip fracture patients with perioperative atrial fibrillation: a nested case-control study.

Background: A scarcity of data exists concerning atrial fibrillation (AF) during the perioperative stage of non-cardiothoracic surgery, particularly orthopedic surgery. In addition, given the frequency and significant impact of AF in the perioperative period, therefore our aim was to identify prognosis and predictors of elderly hip fracture patients with perioperative AF.

Methods: An examination of hip fracture patients at the Third Hospital of Hebei Medical University, who had been hospitalized from January 2018 to October 2020 in succession, was conducted retrospectively.

Risk factors and characteristics of preoperative heart failure in elderly patients with hip fracture and the influence of anemia on prognosis.

Background: Patients with preoperative acute heart failure (AHF) after hip fracture in the elderly have a worse prognosis. We aim to investigate the characteristics, risk factors and postoperative complications of elderly patients with hip fracture complicated with preoperative AHF. We also looked at the effect of the severity of anemia at admission on the prognosis of the above people.

Laser-Regulated Iridium-Diffused Nitrogen-Carbon Sites for Enhanced Hydrazine-Assisted Alkaline Seawater Splitting and Zinc-Hydrazine Batteries.

The current study presents a quick and simple method for synthesizing Ir nanoclusters decorated on an N-doped carbon (NC) matrix via pulsed laser ablation in liquid, followed by pyrolysis. The resulting Ir-NC material acts as a dual-functional electrocatalyst, efficiently facilitating hydrogen generation through the hydrazine oxidation reaction (HzOR) and the hydrogen evolution reaction (HER) in alkaline seawater. The optimized Ir-NC-2 catalyst exhibits a low operating potential of 23 mV versus the reversible hydrogen electrode for HzOR and a remarkably low overpotential of 24 mV for HER, achieving a current density of 10 mA cm in alkaline seawater, surpassing the performance of the Pt/C catalyst.
