Goals: Examine outcomes among homeless patients admitted with gastrointestinal (GI) bleeding, including all-cause mortality and endoscopic intervention rates.

Background: Hospitalizations among homeless individuals have increased steadily since at least 2007 but little is known about GI outcomes in these patients.

Study: The 2010-2014 Healthcare Utilization Project (HCUP) State Inpatient Databases from New York and Florida were used to identify adults admitted with a primary diagnosis of acute upper or lower GI bleed.

Background: The fragility index (FI) represents the number of participants whose status in a trial would have to change from a non-event (not experiencing the primary endpoint) to an event (experiencing the primary endpoint) in order to turn a statistically significant result into a non-significant result. We sought to evaluate the fragility indices of irritable bowel syndrome [IBS-mixed (IBS-M), IBS-constipation (IBS-C), & IBS-diarrhea (IBS-D)] trials.

Methods: Irritable bowel syndrome trials published in high-impact journals were identified from Medline.

Considerable research has focused on hospitalizations for ambulatory care-sensitive conditions (ACSHs), but little of that research has focused on the role played by chronic disease in ACSHs involving children or youth (C/Y). This research investigates, for C/Y, the effects of chronic disease on the likelihood of an ACSH. The database included 699 473 hospital discharges for individuals under 18 in Texas between 2011 and 2015.

Introduction: There is a lack of data on the impact of readmission to the same vs a different hospital following an index hospital discharge in cirrhosis patients.

Methods: We sought to describe rates and predictors of different-hospital readmissions (DHRs) among patients with cirrhosis and also determine the impact on cirrhosis outcomes including all-cause inpatient mortality and hospital costs. Using the national readmissions database, we identified cirrhosis hospitalizations in 2013.

Method: A pre- and post-test with comparison group design was used.

Objectives: We explored differences in criminal convictions between holders and nonholders of a concealed handgun license (CHL) in Texas.

Methods: The Texas Department of Public Safety (DPS) provides annual data on criminal convictions of holders and nonholders of CHLs. We used 2001 to 2009 DPS data to investigate the differences in the distribution of convictions for these 2 groups across 9 types of criminal offenses.
