BACKGROUND AND AIM: The role of octamer-binding transcription factor 4 (Oct4) has been implicated in the clinical prognosis of various kinds of digestive system cancers, but the results remain controversial. The purpose of this meta-analysis is to assess the potential role of Oct4 as a prognostic marker in digestive system tumors. METHODS: Relevant articles were retrieved from Pubmed, Web of Science, and Cochrane Library up to July 2016. The software Stata 12.0 was used to analyze the outcomes, including overall survival (OS), disease-free survival, recurrence-free survival, and clinicopathological characteristics...

The global epidemic of obesity and diabetes underscores the urgency to develop strategies to prevent cardiovascular (CV) disease in this vulnerable population. Clinical guidelines are intended to help the clinician manage these patients, but guidelines are often discordant among professional organizations and not always evidence based. Clinicians must rely upon the best available evidence, and therefore we critically reviewed the evidence behind the American Diabetes Association (ADA) 2016 guidelines on the prevention of CV disease in diabetes...

BACKGROUND: Prolonged mean life expectancy gives rise to a more populated and older patient group. With increasing number of cases during the past decades, older patients are regarded as candidates for microsurgical interventions. Whether advanced patient age is an independent risk factor for microsurgical reconstruction is still an ongoing matter of debate. METHODS: The Cochrane Central Register of Controlled Trials, PubMed, MEDLINE, CINAHL and EMBASE databases were screened for combination of the key words "elderly", "geriatric", "advanced age", "free flap", "microsurgery", free tissue transfer" by using time limits between 1989 and 2015...

BACKGROUND: Ketamine is commonly used for procedural sedation and analgesia (PSA) in children. Evidence suggests it can be administered intranasally (IN). We sought to review the evidence for IN ketamine for PSA in children. METHODS: We performed a systematic review of randomized trials of IN ketamine in PSA that reported any sedation-related outcome in children 0 to 19 years. Trials were identified through electronic searches of MEDLINE (1946-2016), EMBASE (1947-2016), Google Scholar (2016), CINAHL (1981-2016), The Cochrane Library (2016), Web of Science (2016), Scopus (2016), clinical trial registries, and conference proceedings (2000-2016) without language restrictions...
