Predictors of treatment failure following early antibiotic discontinuation in culture-negative, ventilator-associated pneumonia: an observational study.

Introduction: Early antibiotic discontinuation in clinically suspected ventilator-associated pneumonia (VAP) may lead to infection relapse/recurrence and increase mortality. This study aimed to evaluate the incidence and potential predictors of treatment failure with this approach.

Methodology: A retrospective observational study was conducted between September 2014 and November 2016 in a mixed intensive care unit.

Single-port and multiport robot-assisted radical prostatectomy: A meta-analysis.

Objective: To compare the perioperative, oncological, and functional outcomes between single-port robot-assisted radical prostatectomy (SP-RARP) and multiport robot-assisted radical prostatectomy (MP-RARP) via a meta-analysis.

Methods: For relevant articles, three electronic databases, including PubMed, Scopus, and Web of Science, were searched from their inception until January 15, 2022. A meta-analysis has been reported in line with PRISMA 2020 and AMSTAR Guidelines.

Risk factors for cannula-associated arterial thrombosis following extracorporeal membrane oxygenation support: a retrospective study.

Background: Hemostatic dysfunction during extracorporeal membrane oxygenation (ECMO) due to blood-circuit interaction and the consequences of shear stress imposed by flow rates lead to rapid coagulation cascade and thrombus formation in the ECMO system and blood vessels. We aimed to identify the incidence and risk factors for cannula-associated arterial thrombosis (CaAT) post-decannulation.

Methods: A retrospective study of patients undergoing arterial cannula removal following ECMO was performed.

A wearable device for at-home obstructive sleep apnea assessment: State-of-the-art and research challenges.

In the last 3 years, almost all medical resources have been reserved for the screening and treatment of patients with coronavirus disease (COVID-19). Due to a shortage of medical staff and equipment, diagnosing sleep disorders, such as obstructive sleep apnea (OSA), has become more difficult than ever. In addition to being diagnosed using polysomnography at a hospital, people seem to pay more attention to alternative at-home OSA detection solutions.

Attachment of DNA-Wrapped Single-Walled Carbon Nanotubes (SWNTs) for a Micron-Sized Biosensor.

We fabricated a micron-sized biodevice based on the near-infrared photoluminescence (PL) response of single-walled carbon nanotubes (SWNTs). Various biosensors using the unique optical responses of SWNTs have been proposed by many research groups. Most of these employed either colloidal suspensions of dispersed SWNTs or SWNT films on flat surfaces, such as electrodes.

Multiorgan Dysfunction With Severe Cardiac Injury Secondary to Septic Cellulitis Due to Vibrio parahaemolyticus.

infection commonly manifests as gastroenteritis, including diarrhea, abdominal pain, nausea, vomiting, and fever. Although uncommon, has also been associated with wound infection and septic shock. These two manifestations have not been well-reported in medical literature, yet may yield a high risk of death, thus requiring emergent interventions.

An Efficient Method of Observing Diatom Frustules via Digital Holographic Microscopy.

Herein, we propose a convenient method to enable pretreatment of target objects using digital holographic microscopy (DHM). As a test sample, we used diatom frustules ( sp.) as the target objects.

Understanding the Growth Mechanisms of Tin Oxide Nanowires by Chemical Vapor Deposition.

Tin oxides nanowires were prepared by chemical vapor deposition using shadow mask. X-ray diffraction indicated that the products were tetragonal having crystalline structure with lattice constants = 0.474 nm and = 0.

A novel biosensor based on serum antibody immobilization for rapid detection of viral antigens.

In this paper, we represent a label-free biosensor based on immobilization of serum antibodies for rapid detection of viral antigens. Human serum containing specific antibodies against Japanese encephalitis virus (JEV) was immobilized on a silanized surface of an interdigitated sensor via protein A/glutaraldehyde for electrical detection of JEV antigens. The effective immobilization of serum antibodies on the sensor surface was verified by Fourier transform infrared spectrometry and fluorescence microscopy.

DNA sensor development based on multi-wall carbon nanotubes for label-free influenza virus (type A) detection.

This paper describes the DNA immobilization using carbon multi-walled nanotubes (MWCNTs) for direct and label-free detection of influenza virus (type A). The DNA probe was attached on the sensor surface by means of covalent bonding between the amine and phosphate groups of the DNA sequence. The interaction between the DNA probe and the MWCNTs were characterized by Fourier Transform Infrared (FTIR) spectrometry, Raman spectra.
