Early Acute Kidney Injury Recovery in Elderly Patients Undergoing Valve Replacement Surgery.

Objectives: This study was designed to determine the incidence, contributing factors, and prognostic implications of acute kidney injury (AKI) recovery patterns in patients who experienced AKI after valve replacement surgery (VRS).

Design: A retrospective cohort study was conducted.

Setting: The work took place in a postoperative care center in a single large-volume cardiovascular center.

Low-Density Lipoprotein Cholesterol and Mortality Risk in Elderly Patients Undergoing Valve Replacement Surgery: A Propensity Score Matching Analysis.

Background: The prognostic value of low-density lipoprotein cholesterol (LDL-C) in elderly patients is controversial. This study aimed to elucidate the relationship between the preoperative LDL-C and adverse outcomes in elderly patients undergoing valve replacement surgery (VRS).

Methods: A total of 2,552 aged patients (age ≥ 60 years) undergoing VRS were retrospectively recruited and divided into two groups according to LDL-C level on admission: low LDL-C (<70 mg/dL, = 205) and high LDL-C groups (≥ 70 mg/dL, = 2,347).

Red blood cell distribution width: A severity indicator in patients with COVID-19.

Red blood cell distribution width (RDW) was frequently assessed in COVID-19 infection and reported to be associated with adverse outcomes. However, there was no consensus regarding the optimal cutoff value for RDW. Records of 98 patients with COVID-19 from the First People's Hospital of Jingzhou were reviewed.

The effect of preoperative statin treatment on acute kidney injury in elderly patients undergoing valve replacement surgery.

Purposes: The effects of preoperative statin treatment on acute kidney injury (AKI) remain controversial, and current clinical evidence regarding statin use in the elderly undergoing valve replacement surgery (VRS) is insufficient. The present study aimed to investigate the association between preoperative statin treatment and AKI after VRS in the elderly.

Methods: Three thousand seven hundred ninety-one elderly patients (≥ 60 years) undergoing VRS were included in this study and divided into 2 groups, according to the receipt of statin treatment before the operation: statin users (n = 894) and non-users (n = 2897).

The timing of continuous renal replacement therapy initiation in sepsis-associated acute kidney injury in the intensive care unit: the CRTSAKI Study (Continuous RRT Timing in Sepsis-associated AKI in ICU): study protocol for a multicentre, randomised controlled trial.

Introduction: Acute kidney injury (AKI) is one of the most common organ dysfunction in sepsis, and increases the risk of unfavourable outcomes. Renal replacement therapy (RRT) is the predominant treatment for sepsis-associated AKI (SAKI). However, to date, no prospective randomised study has adequately addressed whether initiating RRT earlier will attenuate renal injury and improve the outcome of sepsis.

Predictive Value of Prognostic Nutritional Index on COVID-19 Severity.

The prognostic nutritional index (PNI) has been described as a simple risk-stratified tool for several diseases. We explored the predictive role of the PNI on coronavirus disease 2019 (COVID-19) severity. A total of 101 patients with COVID-19 were included in this retrospective study from January 2020 to March 2020.

The Association of Circulating Selenium Concentrations with Diabetes Mellitus.

Purpose: The relationship between circulating selenium and diabetes mellitus (DM) remains inconsistent. Therefore, the relationship between circulating selenium and DM was investigated in the present study.

Patients And Methods: All participants (aged ≥18 years) were included from the National Health and Nutrition Examination Survey (NHANES) 1999-2006.

Role of Neuromuscular Blocking Agents in Acute Respiratory Distress Syndrome: An Updated Meta-Analysis of Randomized Controlled Trials.

Background: The therapeutic role of neuromuscular blocking agents (NMBA) in patients with acute respiratory distress syndrome (ARDS) remains controversial.

Methods: We systematically reviewed randomized controlled trials investigating the use of NMBA in ARDS patients from inception to July 2019. Relative risk (RR) was calculated for the incidence of barotrauma and mortality using the random-effect or fixed-effect model according to heterogeneity analysis.

Efficacy of vitamin C in patients with sepsis: An updated meta-analysis.

Previous studies have suggested the beneficial effects of vitamin C in patients with sepsis. However, the results could not be reproduced in the subsequent studies. This meta-analysis aimed to reevaluate the value of vitamin C treatment in patients with sepsis.

A new species of the genus (Anura: Microhylidae) from Eastern Nepal.

A new species of the genus Microhyla is described from Jamun Khadi, Jhapa district of eastern Nepal, based on molecular and morphological comparisons. This species is the sister taxon of Microhyla ornata and can be distinguished by a unique vocalization, morphology and molecular phylogeny. The uncorrected genetic divergences based on rRNA gene between the new species and its closest congeners, M.

Research proceedings on amphibian model organisms.

Model organisms have long been important in biology and medicine due to their specific characteristics. Amphibians, especially Xenopus, play key roles in answering fundamental questions on developmental biology, regeneration, genetics, and toxicology due to their large and abundant eggs, as well as their versatile embryos, which can be readily manipulated and developed in vivo. Furthermore, amphibians have also proven to be of considerable benefit in human disease research due to their conserved cellular developmental and genomic organization.

Lung-protective Ventilation in Patients with Brain Injury: A Multicenter Cross-sectional Study and Questionnaire Survey in China.

Background: Over the years, the mechanical ventilation (MV) strategy has changed worldwide. The aim of the present study was to describe the ventilation practices, particularly lung-protective ventilation (LPV), among brain-injured patients in China.

Methods: This study was a multicenter, 1-day, cross-sectional study in 47 Intensive Care Units (ICUs) across China.

[Reactive nitrogen loss pathways and their effective factors in paddy field in southern China].

Based on the literature data, the N20 emission, N leaching, N runoff and NH3 volatilization were compared from different rice production regions and their effective factors were evaluated. The results showed that N2 0 emission, N leaching and N runoff in single rice in Yangtze River basin were higher than in other rice production regions, with N loss of 1.89, 6.

The Screening Performance of Serum 1,3-Beta-D-Glucan in Patients with Invasive Fungal Diseases: A Meta-Analysis of Prospective Cohort Studies.

The serum 1,3-beta-D-glucan (BG) assay aids in the early diagnosis of invasive fungal diseases (IFDs) and has been approved for their diagnosis. However, reports on the screening performance of BG are scarce. We performed a meta-analysis of data extracted from only prospective cohort studies to evaluate the screening performance of the BG assay in the diagnosis of IFDs.

Compensatory recombination phenomena of neurological functions in central dysphagia patients.

We speculate that cortical reactions evoked by swallowing activity may be abnormal in patients with central infarction with dysphagia. The present study aimed to detect functional imaging features of cerebral cortex in central dysphagia patients by using blood oxygen level-dependent functional magnetic resonance imaging techniques. The results showed that when normal controls swallowed, primary motor cortex (BA4), insula (BA13), premotor cortex (BA6/8), supramarginal gyrus (BA40), and anterior cingulate cortex (BA24/32) were activated, and that the size of the activated areas were larger in the left hemisphere compared with the right.
