BACKGROUND/OBJECTIVES: Short-term blood pressure variability (BPV) is affected by multiple factors including the sympathetic nervous system drive. Regarding the latter, the novel interventional technology of renal denervation (RDN), by modulating the sympathetic system activation, could have a beneficial impact on BPV. The aim of the current study is to review and meta-analyze the available evidence on the effect of RDN on short-term BPV. METHODS: We searched Medline/PubMed database until October 2016 for studies with eligible content...

BACKGROUND: Studies of renal denervation (RDN) in patients with apparent treatment resistant hypertension have been hampered by a number of patient and physician related confounders on blood pressure (BP) including poor drug adherence. It remains uncertain whether RDN lowers BP. We aimed to investigate whether the use of sham control is essential in RDN studies or whether systematic use of 24-hour ambulatory BP provides enough information thereby making an invasive sham control redundant...

Long non-coding RNAs (lncRNAs) are emerging as promising prognostic biomarkers in an expanding list of malignant neoplasms. Here, we sought to investigate the strength of associations between lncRNA signatures and clinical outcomes in osteosarcoma. We conducted a systematic search of the online databases from inception to July 2016. Hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) for the primary endpoints of overall survival (OS), progression-free survival (PFS) or event-free survival (EFS) were extracted and meta-analyzed...

BACKGROUND: Stroke is the second most common cause of death, and a common cause of dependency and dementia. Adult vascular risk factors and socioeconomic status (SES) are associated with increased risk, but less is known about early life risk factors, such as education, childhood SES, or intelligence (IQ). METHODS: We comprehensively searched Medline, PsycINFO and EMBASE from inception to November 2015. We included all studies reporting data on >50 strokes examining childhood/premorbid IQ, SES, and education...

Most regression-based tests of the association between a low-count variant and a binary outcome do not protect type 1 error, especially when tests are rejected based on a very low significance threshold. Noted exception is the Firth test. However, it was recently shown that in meta-analyzing multiple studies all asymptotic, regression-based tests, including the Firth, may not control type 1 error in some settings, and the Firth test may suffer a substantial loss of power. The problem is exacerbated when the case-control proportions differ between studies...

INTRODUCTION: Previous studies have reported associations between prenatal cell phone use and child behavioral problems, but findings have been inconsistent and based on retrospective assessment of cell phone use. This study aimed to assess this association in a multi-national analysis, using data from three cohorts with prospective data on prenatal cell phone use, together with previously published data from two cohorts with retrospectively collected cell phone use data. METHODS: We used individual participant data from 83,884 mother-child pairs in the five cohorts from Denmark (1996-2002), Korea (2006-2011), the Netherlands (2003-2004), Norway (2004-2008), and Spain (2003-2008)...

Sven Thoenes, Daniel Oberfeld
Numerous studies have reported that time perception and temporal processing are impaired in schizophrenia. In a meta-analytical review, we differentiate between time perception (judgments of time intervals) and basic temporal processing (e.g., judgments of temporal order) as well as between effects on accuracy (deviation of estimates from the veridical value) and precision (variability of judgments). In a meta-regression approach, we also included the specific tasks and the different time interval ranges as covariates...

BACKGROUND: Hypertension is a chronic condition associated with an increased risk of mortality and morbidity. Renin is the enzyme responsible for converting angiotensinogen to angiotensin I, which is then converted to angiotensin II. Renin inhibitors are a new class of drugs that decrease blood pressure (BP) by preventing the formation of both angiotensin I and angiotensin II. OBJECTIVES: To quantify the dose-related BP lowering efficacy of renin inhibitors compared to placebo in the treatment of primary hypertension...

BACKGROUND: Androgen deprivation therapy (ADT) to treat prostate cancer may be associated with an increased risk of dementia, but existing studies have shown conflicting results. Here we synthesize the literature on the association of ADT for the treatment of prostate cancer with dementia risk. METHODS: We conducted a systematic review of articles reporting the outcome of dementia among individuals with prostate cancer in those exposed to ADT versus a lesser-exposed comparison group (for example, ADT versus no-ADT; continuous versus intermittent ADT) using PubMed (1966-present), Web of Science (1945-present), Embase (1966-present) and PsycINFO (1806-present)...

BACKGROUND: Transverse colon malignancies have been excluded from all randomized controlled trials comparing laparoscopic against open colectomies, potentially due to the advanced laparoscopic skills required for dissecting around the middle colic vessels and the associated morbidity. Concerns have been expressed that the laparoscopic approach may compromise the oncological clearance in transverse colon cancer. This study aimed to comprehensively compare the laparoscopic (LPA) to the open (OPA) approach by performing a meta-analysis of long and short term outcomes...

Tobacco smoke increases the risk of aneurysmal subarachnoid hemorrhage (SAH), as well as complications such as vasospasm. Most patients presenting with aneurysmal SAH smoke, and many survivors continue to smoke after discharge. Neurosurgeons often hesitate to use nicotine replacement therapy (NRT) during hospitalization of patients with SAH due to concerns of inducing vasospasm. We aimed to evaluate the safety and efficacy, and patterns of use of NRT in smokers hospitalized for SAH. We performed a systematic review of MEDLINE, CENTRAL, Embase, and unpublished sources of literature to October 2016 for randomized and observational studies comparing exposure to non-exposure of smoking cessation products in the acute phase of aneurysmal SAH...

The Asp358Ala variant in the interleukin-6 receptor (IL-6R) gene has been implicated in asthma, autoimmune and cardiovascular disorders, but its role in other respiratory conditions such as chronic obstructive pulmonary disease (COPD) has not been investigated. The aims of this study were to evaluate whether there is an association between Asp358Ala and COPD or asthma risk, and to explore the role of the Asp358Ala variant in sIL-6R shedding from neutrophils and its pro-inflammatory effects in the lung. We undertook logistic regression using data from the UK Biobank and the ECLIPSE COPD cohort...
