We sought to compare length-of-stay (LOS), total hospital costs, and readmissions among pulmonary embolism (PE) patients treated with rivaroxaban versus parenterally bridged warfarin. We identified adult PE (primary diagnostic code = 415.1x) patients in the Premier Database (11/2012-9/2015), and included those with ≥1 PE diagnostic test on days 0-2. Rivaroxaban users (allowing ≤2 days of prior parenteral therapy) were 1:1 propensity score matched to patients parenterally bridged to warfarin. ⋯ Results were similar in low-risk patients (0.2-1.0 day and $251-$1751 reductions in LOS and costs, respectively, p ≤ 0.01 for all). In patients with PE, rivaroxaban was associated with reduced LOS and costs, without increased risk of readmission versus parenterally bridged warfarin. Similar results were observed in low-risk PE patients.

Observational Study
Utility of FVC/DLCO ratio to stratify the risk of mortality in unselected subjects with pulmonary hypertension.
In patients with systemic sclerosis, a ratio between forced vital capacity (FVC) and diffusing capacity of carbon monoxide (DLCO, FCV%/DLCO%) >1.5 might be a predictor of pulmonary hypertension (PH). The aim of this study is, therefore, to evaluate whether this index can be used in patients with PH, regardless of etiology. 83 consecutive outpatients with suspected PH at non-invasive work-up underwent spirometry and DLCO test before right heart catheterization (RHC); FVC%/DLCO% ratio was then calculated and compared with mean pulmonary-artery-pressure (mPAP) and mortality at 5-year follow-up. Significant correlations between FVC%/DLCO% and PAsP and mPAP levels were found (p < 0.05). ⋯ Poorer survival rates are observed at follow-up with higher FVC%/DLCO% values (0% for <1, 17.4% for 1-3, 33.3% for >3, p < 0.05), when comparing subjects with either increased PAsP and FVC%/DLCO% values or both with those with lower (log-rank p < 0.05). Even in subjects with mPAP at RHC >25 mmHg, increased FVC%/DLCO% values predicted a worse outcome (p < 0.05). FVC%/DLCO% values are related to mPAP in subjects with suspected PH, and may further stratify the risk of mortality in addition to PAP.

Is polypharmacy an independent risk factor for adverse outcomes after an emergency department visit?
This study aimed at verifying the role of polypharmacy as an independent risk factor for adverse health outcomes in older emergency department (ED) patients. This was a large (n = 2057) sample of older ED patients (≥65 years) participating in an observational cohort study. Polypharmacy and excessive polypharmacy were defined as having 6-9 drug prescriptions and 10 or more drug prescriptions in the last 3 months, respectively. ⋯ A cut-off of 6 had the highest value of the Youden Index in predicting the majority of the adverse outcomes considered. Polypharmacy and excessive polypharmacy are independent risk factors for adverse health outcomes after an ED visit. Further studies are needed to clarify whether drug related issues (such as non-compliance, inappropriate or suboptimal prescribing, adverse drug reactions, and drug-drug or drug-disease interactions) or underlying multimorbidity and disease severity, as well as clinical complexity and frailty, are responsible for the negative outcomes associated with polypharmacy.

Association between weekend admission and mortality for upper gastrointestinal hemorrhage: an observational study and meta-analysis.
Higher in-hospital mortality for weekend vs. weekday admissions has been described. We performed a retrospective study and accompanying meta-analysis to examine the association between weekend admission for upper gastrointestinal hemorrhage (UGIH) and in-hospital mortality. We identified adult admissions to United States (US) hospitals for acute variceal and nonvariceal UGIH between 1/2010 and 12/2012 from the National Inpatient Sample (NIS). ⋯ Weekend admission for nonvariceal UGIH is associated with an increased odds of mortality (aOR 1.09; 95 % CI 1.04-1.15). Weekend admission for UGIH is not associated with a higher odds of in-hospital mortality in our observational study. However, we observed a 9.0 % increase in nonvariceal UGIH mortality for weekend admissions in our meta-analysis.

The evaluation of serum liver enzyme levels is the most used surrogate marker of liver injury in clinical practice. The prevalence and association of abnormal enzyme values with hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, and with other major causes of liver damage (obesity, diabetes, dyslipidemia, and alcohol abuse) were evaluated in individuals attending the surgeries of 14 general practitioners (GPs) working in Messina. Alanine-amino-transferase, aspartate-amino-transferase, and gamma-glutamyl-transpeptidase measurements were measured in 7816 individuals consecutively attending the GP surgeries between January 1, 2011 and June 30, 2012. ⋯ Overall, 57 % of individuals with abnormal liver enzymes had multiple possible causes of liver disease, 28 % one cause, and 15 % no apparent cause. In conclusion, this study shows that 1/5 of individuals attending GP surgeries have altered liver biochemistry and that overweight and metabolic disorders have become the major causes of liver damage even in South Italy, where HBV and HCV were endemic in the past century. Notably, many HCV and HBV patients are still unaware of their infected status, and GPs are essential for their timely identification.
