Comparison of a Potential Hospital Quality Metric With Existing Metrics for Surgical Quality-Associated Readmission.

Importance: The existing readmission quality metric does not meaningfully distinguish readmissions associated with surgical quality from those that are not associated with surgical quality and thus may not reflect the quality of surgical care.

Design, Setting, And Participants: Cohort study using US nationwide administrative data collected on 4 high-volume surgical procedures performed at 103 Veterans Affairs hospitals from October 1, 2007, through September 30, 2014.

An Increasing Neutrophil-to-Lymphocyte Ratio Trajectory Predicts Organ Failure in Critically-Ill Male Trauma Patients. An Exploratory Study.

Although the association of neutrophil proportions with mortality in trauma patients has recently been shown, there is a paucity of research on the association with other outcomes. We sought to investigate the association of neutrophil proportions with organ failure in critically-ill trauma patients. We reviewed a randomly-selected group of trauma patients admitted to our level-1 trauma intensive care unit between July 2007 and December 2016.

Mechanism of a Standalone β-Lactone Synthetase: New Continuous Assay for a Widespread ANL Superfamily Enzyme.

Enzyme-catalyzed β-lactone formation from β-hydroxy acids is a crucial step in bacterial biosynthesis of β-lactone natural products and membrane hydrocarbons. We developed a novel, continuous assay for β-lactone synthetase activity using synthetic β-hydroxy acid substrates with alkene or alkyne moieties. β-Lactone formation is followed by rapid decarboxylation to form a conjugated triene chromophore for real-time evaluation by UV/Vis spectroscopy.

Risk factors for 'microsize' vs. usual myocardial infarctions in the REasons for Geographic and Racial Differences in Stroke (REGARDS) study.

Aims: A recently described phenomenon is that of myocardial infarction (MI) events that meet criteria for MI, but that have very low peak troponin elevations, so-called 'microsize MI'. These events are very common and associated with increased risk of all-cause mortality. Our aim is to compare risk factors for microsize MI vs.

Alcohol-related effects of POST-9/11 discrimination in the context of the great recession: Race/ethnic variation.

Objectives: This study examined whether race/ethnic variation in discrimination is differentially associated with economic adversity during the period of the Great Recession for Blacks and Latinos compared to non-Hispanic Whites, thereby contributing to higher rates of alcohol use and problematic drinking among these groups.

Methods: Structural equation modeling was used to analyze data from a national mail survey.

Results: The association of 9/11-related discrimination with problem-related drinking substantially derives from the association between 9/11-related discrimination and recession-era economic adversity.

Revisiting age-related admission following tonsillectomy in the pediatric population.

Objectives/hypothesis: The objectives of this study were to examine patient outcomes using a 36-month age cutoff as a strict admission criterion following tonsillectomy, and review the safety and determine the plausibility of same-day discharge of children under 3 years old following tonsillectomy.

Study Design: Retrospective chart review.

Methods: A chart review of patients aged 24 to 42 months undergoing tonsillectomy over a 3-year period was conducted.

The role of a sequencing-based clinical intestinal screening test in patients at high-risk for Clostridium difficile and other pathogens: a case report.

Background: Hospitalization and antibiotic treatment can put patients at high risk for Clostridium difficile infection, where a disturbance of the gut microbiome allows for Clostridium difficile proliferation and associated symptoms, including mild, moderate, or severe diarrhea. Clostridium difficile infection is challenging to treat, often recurrent, and leads to almost 30,000 annual deaths in the USA alone. Here we present a case where SmartGut™, an at-home, self-administered sequencing-based clinical intestinal screening test, was used to identify the presence of Clostridium difficile in a patient with worsening diarrhea.

Using health-related quality of life to predict cardiovascular disease events.

Purpose: Although strong associations between self-reported health and mortality exist, quality of life is not conceptualized as a cardiovascular disease (CVD) risk factor. Our objective was to assess the independent association between health-related quality of life (HRQOL) and incident CVD.

Methods: This study used the REasons for Geographic And Racial Differences in Stroke data, which enrolled 30,239 adults from 2003 to 2007 and followed them over 10 years.

Resolution of ascites and hepatic encephalopathy and absence of variceal bleeding in decompensated hepatitis C virus cirrhosis patients.

Background And Aims: The aims of this study were to examine changes in the proportion of decompensated hepatitis C virus (HCV) cirrhosis patients with ascites, hepatic encephalopathy, and variceal bleeding at pretreatment compared to 3 and 12 months post-sustained virological response (SVR) and to compare pretreatment and post-SVR model of end-stage liver disease and Child-Pugh scores and alpha-fetoprotein levels.

Methods: Electronic medical records of 64 decompensated HCV cirrhosis patients who received direct-acting antivirals were reviewed. The McNemar-Bowker test and the Wilcoxon-Signed Rank test were used to compare patient outcomes.

Search for Leptoquarks Coupled to Third-Generation Quarks in Proton-Proton Collisions at sqrt[s]=13 TeV.

Three of the most significant measured deviations from standard model predictions, the enhanced decay rate for B→D^{(*)}τν, hints of lepton universality violation in B→K^{(*)}ℓℓ decays, and the anomalous magnetic moment of the muon, can be explained by the existence of leptoquarks (LQs) with large couplings to third-generation quarks and masses at the TeV scale. The existence of these states can be probed at the LHC in high energy proton-proton collisions. A novel search is presented for pair production of LQs coupled to a top quark and a muon using data at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.
