Angiographic Insights and Endovascular Intervention in Pulmonary Artery Pseudoaneurysms: A Comprehensive Clinical and Pictorial Essay.

Pulmonary artery pseudoaneurysms (PAPs) are rare and can occasionally be overlooked as a cause of hemoptysis. The rupture of PAPs may lead to severe and massive hemoptysis and asphyxiation, necessitating prompt and accurate diagnostic measures, including CT angiography, in conjunction with clinical awareness for adequate management. The aim of this pictorial essay is to establish a strategy for endovascular intervention based on a comprehensive understanding of the etiology and hemodynamics of bronchopulmonary circulation for effective and rapid PAP treatment.

The risk of pregnancy-related adverse outcomes after COVID-19 vaccination: Propensity score-matched analysis with influenza vaccination.

Introduction: Coronavirus 2019 (COVID-19) vaccination rates in pregnant women remain low owing to safety concerns. When evaluating vaccine safety, comparisons with unvaccinated individuals may lead to healthy vaccinee bias. This study aimed to investigate the association between mRNA-based COVID-19 vaccination and pregnancy-related adverse outcomes compared with influenza vaccination.

Improvement of the Stability of Quantum-Dot Light Emitting Diodes Using Inorganic HfO Hole Transport Layer.

One of the major challenges in QLED research is improving the stability of the devices. In this study, we fabricated all inorganic quantum-dot light emitting diodes (QLEDs) using hafnium oxide (HfO) as the hole transport layer (HTL), a material commonly used for insulator. Oxygen vacancies in HfO create defect states below the Fermi level, providing a pathway for hole injection.

Adverse events associated with SARS-CoV-2 neutralizing monoclonal antibodies using the FDA adverse event reporting system database.

The purpose of this study was to analyze the important medical events (IMEs) of anti-severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) monoclonal antibodies using the reports from the United States Food and Drug Administration (US FDA) adverse event reporting system (FAERS) and to detect safety signals. In this study, data from the FAERS from January 2020 to December 2022 were used to investigate signals associated with five monoclonal antibody products (bamlanivimab, bamlanivimab/etesevimab, bebtelovimab, casirivimab/imdevimab, sotrovimab) in coronavirus disease 2019 (COVID-19) patients and one monoclonal antibody product (tixagevimab/cilgavimab) in patients wherein COVID-19 vaccination was not recommended. Disproportionality analyses were conducted using the reporting odds ratio, and an information component to identify safety signals.

Establishing Quality Control Metrics for Large-Scale Plasma Proteomic Sample Preparation.

Large-scale plasma proteomics studies have been transformed due to the multiplexing and automation of sample preparation workflows. However, these workflows can suffer from reproducibility issues, a lack of standardized quality control (QC) metrics, and the assessment of variation before liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. The incorporation of robust QC metrics in sample preparation workflows ensures better reproducibility, lower assay variation, and better-informed decisions for troubleshooting.

Virulence Traits and Azole Resistance in Korean Isolates.

We analyzed the virulence traits and azole resistance mechanisms of 104 isolates collected from 13 Korean hospitals from 1996 to 2022. Of these 104 isolates, 96 (5 blood and 91 ear isolates) belonged to clade II, and 8 (6 blood and 2 other isolates) belonged to clade I. Fluconazole resistance (minimum inhibitory concentration ≥32 mg/L) was observed in 68.

Antibody production and characterization of the nucleoprotein of sever fever with thrombocytopenia syndrome virus (SFTSV) for effective diagnosis of SFTSV.

Background: Severe fever with thrombocytopenia syndrome (SFTS) is an infectious disease caused by the Dabie bandavirus, [or SFTS virus (SFTSV)] that has become increasingly widespread since it was first reported in 2009. The SFTSV comprises three essential single-stranded RNA gene segments, with the S segment encoding the nucleocapsid (N) protein. Since the N protein is the most abundant and stable viral protein, it is a useful diagnostic marker of infection.

Balancing risks and benefits of cannabis use: umbrella review of meta-analyses of randomised controlled trials and observational studies.

Objective: To systematically assess credibility and certainty of associations between cannabis, cannabinoids, and cannabis based medicines and human health, from observational studies and randomised controlled trials (RCTs).

Design: Umbrella review.

Data Sources: PubMed, PsychInfo, Embase, up to 9 February 2022.

PATHWAYS ASSOCIATED WITH POSITIVE SEPSIS SURVIVAL OUTCOMES IN AFRICAN AMERICAN/BLACK AND NON-HISPANIC WHITE PATIENTS WITH URINARY TRACT INFECTION.

Urinary tract infections (UTIs) are a common cause of sepsis worldwide. Annually, more than 60,000 US deaths can be attributed to sepsis secondary to UTIs, and African American/Black adults have higher incidence and case-fatality rates than non-Hispanic White adults. Molecular-level factors that may help partially explain differences in sepsis survival outcomes between African American/Black and Non-Hispanic White adults are not clear.

Usefulness of transcatheter arterial embolization for eighty-three patients with secondary postpartum hemorrhage: Focusing on difference in angiographic findings.

Background: Transcatheter arterial embolization (TAE) has been widely used as an effective and a safe treatment method and was often used as an alternative to the surgical management, but there are limited studies on the efficacy and the safety for patients undergoing their secondary postpartum hemorrhage (PPH).

Aim: To evaluate the usefulness of TAE for secondary PPH focusing on the angiographic findings.

Methods: We conducted a research from January 2008 to July 2022 on all 83 patients (mean: 32 years, range: 24-43 years) presented with secondary PPH and they were treated with TAE in two university hospitals.

Efficacy of Pericapsular Nerve Group Block for Pain Reduction and Opioid Consumption after Total Hip Arthroplasty: A Meta-Analysis of Randomized Controlled Trials.

The aim of this study was to conduct a meta-analysis of randomized controlled trials (RCTs) for comparison of the effectiveness of pericapsular nerve group (PENG) block with that of other analgesic techniques for reduction of postoperative pain and consumption of opioids after total hip arthroplasty (THA). A search of records in the PubMed, Embase, and Cochrane Library, and ClinicalTrials.gov databases was conducted in order to identify studies comparing the effect of the PENG block with that of other analgesics on reduction of postoperative pain and consumption of opioids after THA.

Whole-Genome Sequence Analysis of Isolates from a Patient with Persistent Fungemia and Determination of the Molecular Mechanisms of Multidrug Resistance.

Whole-genome sequencing (WGS) was used to determine the molecular mechanisms of multidrug resistance for 10 serial bloodstream isolates obtained from a neutropenic patient during 82 days of amphotericin B (AMB) or echinocandin therapy. For WGS, a library was prepared and sequenced using a Nextera DNA Flex Kit (Illumina) and the MiseqDx (Illumina) instrument. All isolates harbored the same Msh2p substitution, V239L, associated with multilocus sequence type 7 and a Pdr1p substitution, L825P, that caused azole resistance.

Prevalence and Risk Factors for Iatrogenic Opioid Withdrawal in Medical Critical Care Patients.

Unlabelled: Opioids are the mainstay of pain management and sedation in critically ill patients, which can lead to the development of physiologic tolerance and dependency. The prevalence of iatrogenic opioid withdrawal syndrome (IWS) is reported as 17-32% in the ICU; however, limited evidence exists for the medical ICU patient population.

Objectives: To identify the and risk factors for IWS in adult patients admitted to critical care medicine services who received greater than or equal to 24 hours of continuous opioid infusion therapy.
