Review Meta Analysis
Adverse respiratory effect of acute beta-blocker exposure in asthma: a systematic review and meta-analysis of randomized controlled trials.
β-Blockers are avoided in asthma over concerns regarding acute bronchoconstriction. Risk is greatest following acute exposure, including the potential for antagonism of β2-agonist rescue therapy. ⋯ Selective β-blockers are better tolerated but not completely risk-free. Risk from acute exposure may be mitigated using the smallest dose possible and β-blockers with greater β1-selectivity. β-Blocker-induced bronchospasm responded partially to β2-agonists in the doses given with response blunted more by nonselective β-blockers than selective β-blockers. Use of β-blockers in asthma could possibly be based upon a risk assessment on an individual patient basis.

Review Meta Analysis
EFFECT OF CONTINUOUS POSITIVE AIRWAY PRESSURE (CPAP) ON BLOOD PRESSURE IN PATIENTS WITH OBSTRUCTIVE SLEEP APNEA/HYPOPNEA. A SYSTEMATIC REVIEW AND META-ANALYSIS.
CPAP is considered the therapy of choice for OSA, but the extent to which it can reduce BP is still under debate. We undertook a systematic review and meta-analysis of randomized controlled trials (RCTs) to quantify the effect size of the reduction of BP by CPAP therapy compared with other passive (sham CPAP, tablets of placebo drug, conservative measures) or active (oral appliance, antihypertensive drugs) treatments. ⋯ Therapy with CPAP significantly reduces BP in patients with OSA but with a low effect size. Patients with frequent apneic episodes may benefit the most from CPAP.

Review Meta Analysis
Efficacy and tolerability of treatments for chronic cough: a systematic review and meta-analysis.
Understanding the comparative effectiveness of treatments for patients with unexplained or refractory cough is important to increase awareness of proven therapies and their potential adverse effects in this unique population. ⋯ Although evidence is limited, opioid and certain nonopioid and nonanesthetic antitussives demonstrated efficacy for treating chronic cough in adults. There is a need for further studies in patients with unexplained or refractory cough as well as for more systematic study designs, assessment of patient-centered outcomes, and reporting.

Review Meta Analysis
Short- versus long-duration antibiotic regimens for ventilator-associated pneumonia: a systematic review and meta-analysis.
We performed a systematic review and meta-analysis of short- vs long-duration antibiotic regimens for ventilator-associated pneumonia (VAP). ⋯ Short-course treatment of VAP was associated with more antibiotic-free days. No difference was found regarding mortality and relapses; however, a strong trend for fewer relapses was observed in favor of the long-course treatment, being mostly driven by one study in which the observed relapses were probably more microbiologic than clinical. Additional research is required to elucidate the issue.

Review Meta Analysis
Diagnostic accuracy and safety of semirigid thoracoscopy in exudative pleural effusions: a meta-analysis.
The usefulness of semirigid thoracoscopy in undiagnosed exudative pleural effusions (EPEs) has been variably reported in different studies. Herein, we perform a systematic review and meta-analysis to estimate the overall diagnostic yield and safety of semirigid thoracoscopy in EPE. ⋯ Semirigid thoracoscopy is an efficacious and safe procedure in diagnosis of EPE. Because of the small sample size, larger well-designed trials are required to confirm the results of this study. There is also a need for head-to-head comparison of semirigid and rigid thoracoscopy.
