Incidence of fit test failure during N95 respirator reuse and extended use

JAMA Network Open

2024-01-26

(Press-News.org) About The Study: In this study of 824 N95s used by 412 emergency department health care workers practicing N95 reuse, fit failure occurred in 38.7% of masks after one shift. Trifold N95s had higher incidence of fit failure compared with dome N95s. These results may inform pandemic preparedness, specifically policies related to N95 selection and reuse practices.

Clinical risk and outpatient therapy utilization for COVID-19 in the Medicare population

2024-01-26

About The Study: In this study of patients enrolled in Medicare in 2022, those at the highest risk for severe COVID-19 infection received COVID-19 therapy less often than those with the least risk. Disparities in therapy access were found by patient age, race and ethnicity, Medicaid eligibility, and nursing home residence. Authors: Michael L. Barnett, M.D., of the Harvard T.H. Chan School of Public Health in Boston, is the corresponding author.

Brain drain - nasopharyngeal lymphatics found to be crucial for cerebrospinal fluid outflow

2024-01-26

In a groundbreaking study published in Nature, South Korean researchers led by Director KOH Gou Young of the Center for Vascular Research within the Institute for Basic Science (IBS) have uncovered a distinctive network of lymphatic vessels at the back of the nose that plays a critical role in draining cerebrospinal fluid (CSF) from the brain. The study, sheds light on a previously unknown route for CSF outflow, potentially unlocking new avenues for understanding and treating neurodegenerative conditions. In our brains, ...

CityU neuroscientists uncover the therapeutic potential of low-dose ionizing radiation for traumatic brain injury and ischemic stroke

2024-01-26

Traumatic brain injury (TBI) and ischemic stroke are major public health concerns and leading causes of death and disability worldwide. A research team led by City University of Hong Kong (CityU) neuroscientists recently discovered that low-dose ionizing radiation (LDIR), such as X-ray irradiation, can reduce lesion size and reverse motor deficits in TBI and ischemic stroke mice, demonstrating that LDIR may be a promising therapeutic strategy for TBI and stroke patients. Nearly half of TBI and stroke survivors experience lifelong motor impairment and disability. “Usually, secondary brain damage worsens over time after primary ...

Alliance for Clinical Trials in Oncology study shows positive results for patients with muscle-invasive urothelial carcinoma

2024-01-26

Patients with muscle-invasive urothelial cancer and a high risk of recurrence after surgery may have a new treatment option. The Alliance for Clinical Trials in Oncology today announced positive results from the phase III AMBASSADOR (A031501) trial for the adjuvant treatment of patients with localized muscle-invasive urothelial carcinoma (MIUC) and locally advanced urothelial carcinoma. Late-breaking data from the trial are being presented during an oral abstract session at the 2024 American Society of Clinical ...

Neural network enables objective assessment of breast symmetry

2024-01-26

Waltham — January 25, 2024 — A newly developed neural network is highly accurate in identifying key landmarks important in breast surgery – opening the potential for objective assessment of breast symmetry, suggests a study in the February issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS). The journal is published in the Lippincott portfolio by Wolters Kluwer. "Neural networks and machine learning have the potential to improve evaluation of breast symmetry in reconstructive ...

Boosting the sodium storage performance of Prussian blue analogues via effective etching

2024-01-26

This study is led by Prof. Yuliang Cao and Prof. Yongjin Fang (College of Chemistry and Molecular Sciences, Wuhan University). The experiments were performed by using ammonia etching on highly crystalline Na2NiFe(CN)6 (denoted as NaNiHCF) to activate the sodium storage sites and accelerate the Na+ transport. Fe(CN)6 vacancies and the water molecules in the lattice, which are concomitant during the synthesis, however, lead to poor electrochemical performance. Hence, optimizing the crystal structures of PBAs to boost their electrochemical performance is currently a hot spot in the research ...

Prime editing: Current advances and therapeutic opportunities in human diseases

2024-01-26

This study is led by Prof. Xianqun Fan (Department of Ophthalmology, Shanghai Jiao Tong University School of Medicine Affiliated Ninth People’s Hospital). Gene editing ushers in a new era of disease treatment since many genetic diseases are caused by base-pair mutations in genomic DNA. With the rapid development of genome editing technology, novel editing tools such as base editing and prime editing have attracted public attention, heralding a great leap forward in this field. Prime editing (PE) was proposed by David Liu’s team in 2019, which is characterized ...

Highly oriented perovskite films induced by chiral molecules under magnetic-field control

2024-01-26

In the realm of clean energy, metal halide perovskite solar cells (PSCs) have emerged as a groundbreaking focus, capturing significant attention for their extraordinary advancements. In just over a decade, their certified power conversion efficiency (PCE) has skyrocketed to 26.1%, approaching the upper limits seen in traditional crystalline silicon cells. What sets PSCs apart is their potential to surpass the 30% PCE threshold [1]. The key to optimizing solar devices lies in the deposition of high-quality perovskite films. Achieving minimal defect density and exceptional homogeneity becomes crucial for enhancing device performance. One commonly employed strategy involves introducing ...

Bioinspired hydrogel pattern enhancing atmospheric water harvesting via directional droplet steering

2024-01-26

This study, led by Prof. Jiuhui Qu, Dr. Qinghua Ji, and Dr. Wei Zhang from Tsinghua University, focuses on addressing water scarcity by exploring atmospheric water harvesting. The water in the air originates from both natural and forced evaporation, with condensation being the final and crucial step in water harvesting. Condensation involves nucleation, growth, and shedding of water droplets, which are then collected. However, uncontrollable growth of condensed droplets leading to surface flooding is a pressing challenge due to insufficient driving forces, posing a threat to sustainable condensation. To expedite this process and achieve orderly ...

App enhances nurses' care coordination competency for critically ill patients

2024-01-26

To improve the care coordination competency of nurses involved in the management of critically ill patients on life support, an electronic app—NCCCS—was developed by Associate Professor　Chie Takiguchi of Toho University and Professor Tomoko Inoue of International University of Health and Welfare. The NCCCS app utilizes the scoring system referred to as the Nurses' Care Coordinate Competency Scale (NCCCS), developed by Dr. Takiguchi et al. in 2017, and it is currently being translated into Chinese, Italian, Polish, and Persian. This app offers immediate feedback to nurses caring for critically ill patients on life ...
