Review Meta Analysis
Stroke, Major Bleeding and Mortality Outcomes in Warfarin Users with Atrial Fibrillation and Chronic Kidney Disease: A Meta-analysis of Observational Studies.
The use of warfarin in patients with atrial fibrillation (AF) and chronic kidney disease (CKD) can be problematic because of increased bleeding risk. We performed a systematic review and meta-analysis of observational studies that evaluated the use of warfarin in patients with AF and CKD to evaluate the risks of ischemic stroke/thromboembolism, major bleeding, and mortality. ⋯ Based on this meta-analysis, the use of warfarin for AF may have an unfavorable risk/benefit ratio in patients with end-stage CKD but not in those with non-end-stage CKD.

Randomized Controlled Trial
The effects of azithromycin in treatment resistant cough: a randomised, double blind, placebo controlled trial.
Chronic cough is a common clinical problem worldwide. Although many patients have underlying precipitating conditions such as asthma, gastroesophageal reflux, or rhinitis, many remain symptomatic despite treating these conditions. New approaches are needed for the treatment of this group of patients. ⋯ Treatment with low-dose azithromycin for 8 weeks did not significantly improve LCQ score compared with placebo. The use of macrolides for treatment-resistant cough cannot be recommended from this study, but they may have a place in the treatment of chronic cough associated with asthma; this is worthy of further investigation.

In-laboratory, attended polysomnography has long been the gold standard for the diagnosis of sleep-disordered breathing (SDB). In recent years, economic pressures and long wait times have driven interest in home sleep testing, which has, in turn, led to the development of algorithms that bypass the sleep laboratory in favor of portable monitoring studies and in-home initiation of positive airway pressure therapy. ⋯ In the inpatient setting, in which SDB is both highly prevalent and associated with adverse outcomes in certain populations, the literature is evolving on the use of portable monitors to expedite diagnosis and treatment of SDB. This review discusses society guidelines and recent research in the growing field of portable monitoring.

Reducing hospital readmissions has attracted attention from many stakeholders. However, the characteristics of 30-day readmissions after asthma-related hospital admissions in adults are not known. It is also unclear whether older adults are at higher risk of 30-day readmission. ⋯ After asthma-related admission, 14.5% of patients had 30-day readmission with wide range of principal diagnoses. Compared with younger adults, older adults had higher 30-day readmission rates and proportions of nonrespiratory diagnoses.
