Review Meta Analysis
Effect of early goal directed therapy in the treatment of severe sepsis and/or septic shock.
Many investigators have reproduced the mortality reduction shown in the original trial of early goal directed therapy (EGDT) in patients with severe sepsis and/or septic shock. Three large randomized controlled trials (RCTs) found neutral results when compared to usual care and a modified form of EGDT. Some have interpreted these studies as a reason to question the efficacy of EGDT. ⋯ EGDT significantly reduced mortality in patients with severe sepsis and/or septic shock over 15 years since its publication. Recent studies examining usual care with EGDT have similar mortality benefit because of the diminished treatment effect. This treatment effect is diminished for multiple reasons. With progress in the management of this disease the benefit of EGDT on overall mortality has become comparable with the usual care for sepsis patients. This is because many of the components of EGDT have been incorporated into usual care protocols. As a result, the conclusion that EGDT is ineffective cannot be made. A more rigorous RCT which adjusts for the factors that narrows the treatment effect between groups is required. Given the current state of sepsis care and equipoise that exist, this would be difficult.

Meta Analysis
Effects of telmisartan on fat distribution: a meta-analysis of randomized controlled trials.
Several meta-analyses have confirmed the positive metabolic effects of telmisartan, an angiotensin II receptor blocker that can also act as a partial peroxisome proliferator-activated receptor-γ agonist, compared to those of other angiotensin II receptor blockers. These effects include decreased fasting glucose, glycosylated hemoglobin, interleukin-6, and tumor necrosis factor-α levels. However, no systemic analysis of telmisartan's effects on body fat distribution has been performed. We performed a meta-analysis of randomized controlled telmisartan trials to investigate its effects on body weight, fat distribution, and visceral adipose reduction. ⋯ The findings suggest that telmisartan affected fat distribution, inducing visceral fat reduction, and thus could be useful in hypertensive patients with obesity/overweight, metabolic syndrome, or glucose intolerance.

Review Meta Analysis
The prognostic role of FIGO stage in patients with vulvar cancer: a systematic review and meta-analysis.
To perform a meta-analysis examining the survival of patients with vulvar cancer based on the 2009 International Federation of Gynecology and Obstetrics (FIGO) staging system. ⋯ More advanced 2009 FIGO stage and greater number of LN metastases are associated with worse outcomes in patients with vulvar cancer.

This study evaluates the role of hypothyroidism in obstructive sleep apnea (OSA) by comparing the OSA indices in hypothyroid OSA (OSA-HYPOT) with euthyroid OSA (OSA-EUTHY) patients. ⋯ Hypothyroidism is found to be associated with severity of OSA. However, obesity can be a confounder in the outcomes observed herein.

Meta Analysis
The efficacy of pregabalin in patients with moderate and severe pain due to diabetic peripheral neuropathy.
Objective To compare the therapeutic response to pregabalin in patients with moderate or severe painful diabetic peripheral neuropathy (pDPN). Research design and methods Data were pooled from 11 placebo-controlled trials to evaluate the efficacy of pregabalin flexible or fixed dose (150, 300 or 600 mg/day) in pDPN patients with mean baseline pain scores of ≥4 to <7 (moderate) or ≥7 to ≤10 (severe). Last observation carried forward imputation was used. ⋯ Conclusions Pregabalin was effective in pDPN patients with both moderate and severe baseline pain. Patients with severe pain exhibited greater improvements in pain and PRSI than patients with moderate pain. Pain severity may, in part, predict therapeutic response to pregabalin.
