Continuous positive airway pressure (CPAP) is the first-line treatment of obstructive sleep apnea (OSA). Obstructive sleep apnea is a predictor of cardiovascular (CV) events. In this meta-analysis, we evaluated the effect of CPAP on left ventricular ejection fraction (LVEF), CV events, CV mortality, and all-cause mortality in patients with OSA. ⋯ There was a nonsignificant reduction in all-cause mortality (hazard ratio [HR]: 0.92, 95% CI: 0.73-1.15) but a significant reduction of 66% in the risk of CV mortality associated with the CPAP treatment (HR: 0.34, 95% CI: 0.17-0.68, P = .002). There was a nonsignificant reduction in the risk of CV events in the CPAP-treated patients (HR: 0.84, 95% CI: 0.60-1.18, P = .31). Our meta-analyses showed that CPAP treatment improves LVEF and could have a beneficial effect on CV mortality.

Intermediate-risk pulmonary embolism (PE), also known as submassive PE, occurs in a substantial group of patients and carries a significant mortality risk. With adequate risk stratification, catheter-directed techniques could be used as a therapeutic approach in the intermediate-risk PE. ⋯ This narrative review will focus on the major studies involving the efficacy and safety of UCDT in the intermediate-risk PE population. Prospective, randomized clinical trials with long-term follow-up and a large sample size are needed for further evaluation of mortality benefit and to further define which subgroup of patients may benefit from this novel endovascular technique.

Review Meta Analysis
Efficacy of Drug-Eluting Balloons for Patients With In-Stent Restenosis: A Meta-Analysis of 8 Randomized Controlled Trials.
The optimal treatment for in-stent restenosis (ISR) of both bare-metal stent (BMS) and drug-eluting stent (DES) is currently unclear. The aim of this meta-analysis was to assess the role of drug-eluting balloon (DEB) as an optional treatment for ISR. We searched PubMed, MEDLINE, EMBASE, BIOS, and Web of Science from 2005 to July 2014. ⋯ However, the differences were not significant between DEB treatment and DES treatment in all primary and secondary end points. The DEB was a better option to treat ISR when compared to POBA. However, it had similar effects as DES.

Review Meta Analysis
Optimal Duration of Dual Antiplatelet Therapy After DES Implantation: A Meta-Analysis of 11 Randomized Trials.
Despite new-generations of drug-eluting stents (DESs), the optimal duration of dual antiplatelet therapy (DAPT) remains controversial. We performed a meta-analysis of randomized trials (RTs) evaluating the effectiveness and safety of shorter versus longer DAPT duration strategies in patients undergoing percutaneous coronary interventions with DES. Literature and main scientific session abstracts were searched. ⋯ Similar results were observed when comparing 3 to 6 versus 12 months DAPT, while a significant increase in recurrent ischemic events was found for 6 to 12 months DAPT versus extended treatment (myocardial infarction: OR [95%CI] = 1.66 [1.37-2], P < .00001; phet = 0.13 and ST: OR [95%CI] = 2.47 [1.72-3.45], P < .00001; phet = 0.12), however, counterbalanced by a significant reduction in major bleeding (OR [95%CI] = 0.60 [0.47-0.76], P < .0001; phet = 0.38) and a trend in lower mortality. Thus, among selected patients undergoing DES implantation, a shorter DAPT strategy is associated with reduction in mortality and major bleeding but a higher risk of myocardial infarction and ST. A short duration (3-6 months) of DAPT appears as the safest strategy, while a prolonged duration (24-36 months) reduces thrombotic complications but with an excess in major bleeding complications.

Damage of small nerve fibers may lead to a large variety of clinical symptoms. Small-fiber neuropathy underlies the symptoms of painful diabetic neuropathy, which may decrease quality of life. It also contributes to the poor prognosis of diabetic neuropathy because it plays a key role in the pathogenesis of foot ulceration and autonomic neuropathy. ⋯ Corneal confocal microscopy and punch skin biopsy are considered gold standards, but noninvasive functional tests are also diagnostically useful. However, in routine clinical practice, small-fiber neuropathy is diagnosed by its typical clinical presentation. Finally, prompt treatment should be initiated following diagnosis.
