Building a Foundation for High-Quality Health Data: Multihospital Case Study in Belgium.

Background: Data quality is fundamental to maintaining the trust and reliability of health data for both primary and secondary purposes. However, before the secondary use of health data, it is essential to assess the quality at the source and to develop systematic methods for the assessment of important data quality dimensions.

Objective: This case study aims to offer a dual aim-to assess the data quality of height and weight measurements across 7 Belgian hospitals, focusing on the dimensions of completeness and consistency, and to outline the obstacles these hospitals face in sharing and improving data quality standards.

The tyrosine kinase Yes1 is a druggable host factor of HEV.

Background: HEV is a positive-sense, single-stranded RNA virus of the Hepeviridae family. Although HEV accounts for more than 3 million symptomatic cases of viral hepatitis per year, specific anti-HEV therapy and knowledge about HEV pathogenesis are scarce.

Methods: To gain a deeper understanding of the HEV infectious cycle and guide the development of novel antiviral strategies, we here used an RNAi mini screen targeting a selection of kinases, including mitogen-activated protein kinases, receptor tyrosine kinases, and Src-family kinases.

Respiratory virus detection and sequencing from negative SARS-CoV-2 rapid antigen tests.

Genomic epidemiology offers important insight into the transmission and evolution of respiratory viruses. We used metagenomic sequencing from negative SARS-CoV-2 antigen tests to identify a wide range of respiratory viruses and generate full genome sequences, offering a streamlined mechanism for broad respiratory virus genomic surveillance.

Regulation of translation in response to iron deficiency in human cells.

Protein synthesis is a highly energy-consuming process that is downregulated in response to many environmental stresses or adverse conditions. Studies in the yeast Saccharomyces cerevisiae have shown that bulk translation is inhibited during adaptation to iron deficiency, which is consistent with its requirement for ribosome biogenesis and recycling. Although iron deficiency anemia is the most common human nutritional disorder, how iron modulates translation in mammals is poorly understood.

Warfarin, not direct oral anticoagulants or antiplatelet therapy, is associated with increased bleeding risk in emergency general surgery patients: Implications in this new era of novel anticoagulants: An EAST multicenter study.

Introduction: This study aimed to assess perioperative bleeding complications and in-hospital mortality in patients requiring emergency general surgery presenting with a history of antiplatelet (AP) versus direct oral anticoagulant (DOAC) versus warfarin use.

Methods: A prospective observational study across 21 centers between 2019 and 2022 was conducted. Inclusion criteria were age 18 years or older, and DOAC, warfarin, or AP use within 24 hours of an emergency general surgery procedure.

Genomic Analyses of Major SARS-CoV-2 Variants Predicting Multiple Regions of Pathogenic and Transmissive Importance.

The rapid evolution of SARS-CoV-2 has fueled its global proliferation since its discovery in 2019, with several notable variants having been responsible for increases in cases of coronavirus disease 2019 (COVID-19). Analyses of codon bias and usage in these variants between phylogenetic clades or lineages may grant insights into the evolution of SARS-CoV-2 and identify target codons indicative of evolutionary or mutative trends that may prove useful in tracking or defending oneself against emerging strains. We processed a cohort of 120 SARS-CoV-2 genome sequences through a statistical and bioinformatic pipeline to identify codons presenting evidence of selective pressure as well as codon coevolution.

Design Rules for the Sequestration of Viruses into Polypeptide Complex Coacervates.

Encapsulation is a strategy that has been used to facilitate the delivery and increase the stability of proteins and viruses. Here, we investigate the encapsulation of viruses via complex coacervation, which is a liquid-liquid phase separation resulting from the complexation of oppositely charged polymers. In particular, we utilized polypeptide-based coacervates and explored the effects of peptide chemistry, chain length, charge patterning, and hydrophobicity to better understand the effects of the coacervating polypeptides on virus incorporation.

The impact of correction methods on rare-event meta-analysis.

Meta-analyses have become the gold standard for synthesizing evidence from multiple clinical trials, and they are especially useful when outcomes are rare or adverse since individual trials often lack sufficient power to detect a treatment effect. However, when zero events are observed in one or both treatment arms in a trial, commonly used meta-analysis methods can perform poorly. Continuity corrections (CCs), and numerical adjustments to the data to make computations feasible, have been proposed to ameliorate this issue.

Human mRNA in saliva can correctly identify individuals harboring acute infection.

There are a variety of clinical and laboratory criteria available to clinicians in controlled healthcare settings to help them identify whether an infectious disease is present. However, in situations such as a new epidemic caused by an unknown infectious agent, in health screening contexts performed within communities and outside of healthcare facilities or in battlefield or potential biowarfare situations, this gets more difficult. Pathogen-agnostic methods for rapid screening and triage of large numbers of people for infection status are needed, in particular methods that might work on an easily accessible biospecimen like saliva.

Non-Traumatic Hepatobiliary Emergencies.

Hepatobiliary emergencies typically present with a constellation of different symptoms including abdominal pain, fevers, nausea, vomiting, jaundice, coagulopathy, and in some instances, encephalopathy. The differential can be broad and may include infectious, inflammatory, and even iatrogenic etiologies. Workup with appropriate lab and imaging studies can help discern between different pathologies and thus guide their management.

Association Between Mental Health Burden, Clinical Presentation, and Outcomes in Individuals With Symptomatic Peripheral Artery Disease: A Scientific Statement From the American Heart Association.

Along with the rising burden of peripheral artery disease (PAD), mental health concerns are increasingly being recognized as a comorbidity to address in the chronic disease management of symptomatic PAD. Apart from a high prevalence of comorbid mental health conditions, the role of pain and changing health behaviors and the broader impacts of illness and adaptation to living with PAD require specialized behavioral health expertise. This scientific statement builds a case that this expertise should be integrated within the multidisciplinary PAD team.

Resolvin D2-G-Protein Coupled Receptor 18 Enhances Bone Marrow Function and Limits Steatosis and Hepatic Collagen Accumulation in Aging.

Aging is associated with nonresolving inflammation and tissue dysfunction. Resolvin D2 (RvD2) is a proresolving ligand that acts through the G-protein-coupled receptor called GPR18. Unbiased RNA sequencing revealed increased Gpr18 expression in macrophages from old mice, and in livers from elderly humans, which was associated with increased steatosis and fibrosis in middle-aged (MA) and old mice.

Help a mother out: The impact of acute care surgeon response in postpartum hemorrhage.

Introduction: A Code White (CW) activation is a hospital-wide alert for postpartum hemorrhage (PPH) and acute care surgeons (ACS) were added to the response team to assist in resuscitation. A multidisciplinary training program was also implemented. This study aimed to evaluate the impact of ACS involvement and training on maternal outcomes.

To observe or not to observe: Evaluation of the modified brain injury guideline management of small volume intracranial hemorrhage.

Introduction: Patients with small volume intracranial hemorrhage (ICH) are categorized as modified Brain Injury Guidelines (mBIG) 1 and are managed with a 6-h emergency department (ED) observation period. The current study aimed to describe the mBIG 1 patient population and determine the utility of the ED observation period.

Methods: A retrospective analysis was performed on trauma patients with small volume ICH.

Anticoagulation in emergency general surgery: Who bleeds more? The EAST multicenter trials ACES study.

Background: While direct oral anticoagulant (DOAC) use is increasing in the Emergency General Surgery (EGS) patient population, our understanding of their bleeding risk in the acute setting remains limited. Therefore, the objective of this study was to determine the prevalence of perioperative bleeding complications in patients using DOACs versus warfarin and AP therapy requiring urgent/emergent EGS procedures (EGSPs).

Methods: This was a prospective observational trial, conducted between 2019 and 2022, across 21 centers.

Critical Care Echocardiography.

Ultrasonography is increasingly applied in the critical care setting. With advancements in technology, ultrasonography has become easier to use, with smaller machines, and more fundamental to patient assessment. Ultrasonography is a hands-on tool that brings real-time, dynamic information to the bedside.

Demographics, Birth Parameters, and Social Determinants of Health Among Opioid-Exposed Mother-Infant Dyads Affected by Neonatal Abstinence Syndrome in Pennsylvania, 2018-2019.

Objectives: To characterize demographics, birth parameters, and social determinants of health among mother-infant dyads affected by neonatal abstinence syndrome (NAS) in Pennsylvania.

Methods: We linked 2018-2019 NAS surveillance data to birth record data using probabilistic methods and then geospatially linked to local social determinants of health data based on residential address. We generated descriptive statistics and used multivariable mixed-effects logistic regression to model the association between maternal characteristics, birth parameters, social determinants of health, and NAS.

Human CD4 cytotoxic T lymphocytes mediate potent tumor control in humanized immune system mice.

Efficacy of immune checkpoint inhibitors in cancers can be limited by CD8 T cell dysfunction or HLA-I down-regulation. Tumor control mechanisms independent of CD8/HLA-I axis would overcome these limitations. Here, we report potent CD4 T cell-mediated tumor regression and memory responses in humanized immune system (HIS) mice implanted with HT-29 colorectal tumors.

Quantitative reconstitution of yeast RNA processing bodies.

Many biomolecular condensates appear to form through liquid-liquid phase separation (LLPS). Individual condensate components can often undergo LLPS in vitro, capturing some features of the native structures. However, natural condensates contain dozens of components with different concentrations, dynamics, and contributions to compartment formation.

Optimal Trauma Activation Criteria for "Found Down" Patients.

Introduction: Patients who are found down (FD) with unknown mechanism of injury pose a triage dilemma. At the study institution, this population with any "suspicion of trauma" criteria were previously triaged as a trauma team activation (TTA) but due to high rates of mis-triage was modified to "signs of trauma." The purpose of this study is to compare injured and uninjured FD patients to identify patient characteristics and outcomes, and to evaluate triage accuracy of signs of trauma.
