Association of Area Deprivation Index With Mortality in Critically Ill Adults With COVID-19.

Background: Various social determinants of health have been established as significant risk factors for COVID-19 transmission, prevalence, incidence, and mortality. Area deprivation index (ADI, a composite score made up of educational, housing, and poverty markers) is an accepted multidimensional social determinants of health measure. Little is known about how structural social determinants of health before hospitalization, including ADI, may affect mortality related to COVID-19 in critically ill patients.

A Retrospective Cohort Study Examining the Validation of the Modified Duke Activity Status Index in the Non-cardiac Surgical Population.

Purpose: We aimed to ascertain if the Duke Activity Status Index (DASI) and its simplified variants predict 30-day mortality and myocardial injury after major non-cardiac surgery in at-risk patients.

Design: Retrospective cohort study.

Methods: We included 4,199 patients to validate the DASI and its variants in predicting the same composite outcome in patients with risk factors for coronary artery disease.

ICU outcomes following a Central Line Associated Blood Stream Infections (CLABSI) reduction quality improvement project.

Background: Central Line Associated Blood Stream Infections (CLABSI) are significant complications for hospitalized patients. Several different approaches have been used to reduce CLABSI.

Objective: This study aimed to (1) describe a systematic approach used to analyze and reduce CLABSI rates in a surgical ICU (SICU) at a quaternary care medical facility (CLABSI reduction bundle) and (2) examine the association of the bundle on CLABSI rates in the SICU, compared to six unexposed health system ICUs.

The impact of bleeding on outcomes following lung transplantation: a retrospective analysis using the universal definition of perioperative bleeding.

Background: Lung transplantation (LT) represents a high-risk procedure for end-stage lung diseases. This study describes the outcomes of patients undergoing LT that require massive transfusions as defined by the universal definition of perioperative bleeding (UDPB).

Methods: Adult patients who underwent bilateral LT at a single academic center were surveyed retrospectively.

The association of TNF inhibitor use with incident cardiovascular events in radiographic axial spondyloarthritis.

Background: Whether tumor necrosis factor inhibitor (TNFi) use is cardioprotective among individuals with radiographic axial spondyloarthritis (r-axSpA), who have heightened cardiovascular (CV) risk, is unclear. We tested the association of TNFi use with incident CV outcomes in r-axSpA.

Methods: We identified a r-axSpA cohort within a Veterans Affairs database between 2002 and 2019 using novel phenotyping methods and secondarily using ICD codes.

Pain trajectories after bilateral orthotopic lung transplantation surgery performed via a clamshell incision.

Introduction: The nature, intensity, and progression of acute pain after bilateral orthotopic lung transplantation (BOLT) performed via a clamshell incision has not been well investigated. We aimed to describe acute pain after clamshell incisions using pain trajectories for the study cohort, in addition to stratifying patients into separate pain trajectory groups and investigating their association with donor and recipient perioperative variables.

Methods: After obtaining IRB approval, we retrospectively included all patients ≥18 years old who underwent primary BOLT via clamshell incision at a single center between January 1, 2017, and June 30, 2022.

Interplay between noxious heat sensitivity and temporal summation magnitude in patients with fibromyalgia and long-term opioid use.

Introduction: In chronic pain conditions such as fibromyalgia (FM), pain amplification within the central nervous system, or "central sensitization," may contribute to the development and maintenance of chronic pain. Chronic pain treatments include opioid therapy, and opioid therapy may maladaptively increase central sensitization, particularly in patients who take opioids long-term. However, it has remained unknown how central sensitization is impacted in patients who use opioids long-term.

An Analysis of Outcomes Following a Central Line Associated Blood Stream Infections (CLABSI) Reduction Quality Improvement Project in a Tertiary Care Center.

Central Line Associated Blood Stream Infections (CLABSI) continue to be a significant complication for hospitalized patients. Hospitals have used various strategies to reduce CLABSI events due to the significant complications and associated costs. In this QI analysis, we examined the impact of a CLABSI reduction quality improvement project within a single ICU at a tertiary care medical center.

Evaluating the Association Between Fibrinogen and Rotational Thromboelastometry and the Progression to Severe Obstetric Hemorrhage.

Aim: This study aims to investigate the ability of fibrinogen and rotational thromboelastometry (ROTEM) parameters measured at obstetric hemorrhage protocol initiation to predict severe hemorrhage.

Methods: In this retrospective study we included patients whose hemorrhage was managed with an obstetric massive transfusion protocol. Fibrinogen and ROTEM parameters EXTEM clotting time (CT), clot formation time (CFT), alpha angle, A10, A20, lysis index 30 min after CT (LI30), FIBTEM A10, A20, were measured at initiation of the protocol with transfusion based on a predefined algorithm.

Procalcitonin levels in pregnancy: A systematic review and meta-analysis of observational studies.

Background: The utility of procalcitonin to identify obstetric sepsis is unknown.

Objective: To calculate the mean (range) procalcitonin in pregnancy among healthy women not in labor (group 1), healthy women in labor (group 2), and women with preterm prelabor rupture of membranes (PPROM) without clinical chorioamnionitis (group 3).
