Statewide Variation in Practices and Charges for Primary Spontaneous Pneumothorax in Maryland, United States: A Retrospective Study.

Background: The optimal treatment for primary spontaneous pneumothorax (PSP) remains undefined. Furthermore, the overall utilization and costs of various treatment approaches are incompletely understood. We investigated hospital charges and resource utilization by management strategy across the state of Maryland in adult and pediatric patients with PSP.

Pediatric Firearm Reinjury: A Retrospective Statewide Risk Factor Analysis.

Introduction: Pediatric firearm injuries are a significant public health concern in the United States. This study examines risk factors for firearm reinjury in Maryland's pediatric population.

Methods: Pediatric patients (age 0-19 y) who presented to any hospital in Maryland with a firearm injury between October 1, 2015, and December 31, 2019, were identified in the Maryland Health Services Cost Review Commission database and were followed for repeat firearm injuries through March 31, 2020.

BNP and NT-proBNP as prognostic biomarkers for the prediction of adverse outcomes in HFpEF patients: A systematic review and meta-analysis.

Heart failure with preserved ejection fraction (HFpEF) presents a challenge in clinical practice due to its complexity and impact on morbidity and mortality. The aim of this systematic review and meta-analysis (SR/MA) was to evaluate the value of B-Type Natriuretic Peptide (BNP) and NT-proBNP in predicting overall adverse outcomes, cardiovascular events, and mortality, in patients with HFpEF. This SR/MA included observational studies and randomized controlled trials (RCTs) that reported the use of BNP and NT-proBNP as prognostic biomarkers for adverse outcomes in HFpEF patients.

Improving Hospital Palliative Care Between COVID-19 Waves: A Retrospective Cohort Study.

Context: A specialist palliative care service in an acute hospital characterized care patterns during the first wave of the COVID-19 pandemic. There were delayed referrals for minoritized ethnic groups. COVID-19 treatments (dexamethasone, anticoagulation, remdesivir) alongside service changes were introduced in the second wave.

Failure to Significantly Reduce Radiation Exposure in Children with Suspected Appendicitis in the United States.

Background: Ultrasound (US) or magnetic resonance imaging (MRI) is recommended over computed tomography (CT) as the initial imaging modality when considering a diagnosis of appendicitis in children. This reduces unnecessary radiation exposure and has excellent accuracy. We hypothesized a significant increase in US utilization and a reduction in CT utilization in hospitals across the United States.
