BACKGROUND: Several observational studies have investigated interleukin-18 (IL-18) gene polymorphisms with regard to susceptibility to hepatitis C virus (HCV) infection, but the results have been inconsistent. AIM: To evaluate the relationships between functional polymorphisms in the IL-18 gene and an individual's susceptibility to HCV infection, a meta-analysis was performed. Methods: A literature search was conducted using the PubMed, EMBASE, Web of Science and China BioMedicine databases to investigate the correlation between IL-18 gene polymorphisms and susceptibility to HCV infection...

Background: Culture-independent diagnostic tests (CIDTs) are increasingly used to diagnose Campylobacter infection in the Foodborne Diseases Active Surveillance Network (FoodNet). Because CIDTs have different performance characteristics compared with culture, which has been used historically and is still used to diagnose campylobacteriosis, adjustment of cases diagnosed by CIDT is needed to compare with culture-confirmed cases for monitoring incidence trends. Methods: We identified the necessary parameters for CIDT adjustment using culture as the gold standard, and derived formulas to calculate positive predictive values (PPVs)...

Importance: Patients with vascular malformations (VAMs) and vascular overgrowth syndromes have lower health-related quality of life (HRQoL) attributable to social stigmatization, poor mental health, severity, and pain. However, the factors that contribute to this decreased HRQoL are not clear. Objective: To perform a systematic review and meta-analysis of studies that used validated HRQoL instruments to compare the HRQoL of persons with VAMs with the US general population...

BACKGROUND: Off-pump coronary artery bypass grafting (OPCAB) is one of the standard treatments for coronary artery disease (CAD) while hybrid coronary revascularization (HCR) represents an evolving revascularization strategy. However, the difference in outcomes between them remains unclear. OBJECTIVE: We performed a meta-analysis to compare the short-term and mid-term outcomes of HCR versus OPCAB for the treatment of multivessel or left main CAD. METHODS: We searched the PubMed, EMBASE, Web of Science and Cochrane databases to identify related studies and a routine meta-analysis was conducted...

BACKGROUND AND OBJECTIVES: Chronic kidney disease (CKD) is a global health burden and is independently associated with increased cardiovascular disease risk. Assessment of cardiovascular risk in the general population using prognostic models based on routinely collected risk factors is embedded in clinical practice. In CKD, prognostic models may misrepresent risk due to the interplay of traditional atherosclerotic and non-traditional risk factors. This systematic review's aim was to identify routinely collected risk factors for inclusion in a CKD-specific cardiovascular prognostic model...

OBJECTIVE: To evaluate the efficacy and safety of gemcitabine (GEM) at 30 min standard-dose infusion (30 min-SDI) compared with prolonged low-dose infusion (P-LDI) in patients with advanced non-small-cell lung cancer (NSCLC). METHODS: Electronic databases including Pubmed, EMbase, Cochrane Library, CNKI, CBM, and VIP were searched using keywords "GEM", "P-LDI", and "NSCLC". Review Manager 5.3 was used to perform the meta-analysis. Primary endpoints were overall response rate (ORR) and 1-year survival rate (1-year SR)...

Posttraumatic enophthalmos due to isolated or complex orbital fractures can contribute to diplopia. Current evidence recommends early repair. However, little is known about the outcome of enophthalmos correction when repair occurs beyond 30 days after trauma. In this systematic review, the authors aim to evaluate the current evidence on functional outcomes after delayed repair of posttraumatic enophthalmos.Two independent assessors undertook a systematic review of the literature using multiple databases. The authors' inclusion criteria identified studies involving patients at least 14 years of age who had surgical correction of persistent enophthalmos 30 days after initial trauma...

BACKGROUND: Several studies suggest that local warming therapy (LWT) may help to treat chronic wounds, such as pressure ulcers, venous ulcers, arterial ulcers, and diabetic foot ulcers. However, evidence supporting the efficacy of this treatment is still incomplete. This study aimed to assess the effects of LWT in treating chronic wounds. METHODS: For this review, we searched the Cochrane Wounds Specialized Register (March 6, 2017); the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2017 issue 3); Ovid MEDLINE (1946 to March 6, 2017); Ovid Embase (1974 to March 6, 2017); EBSCO CINAHL (1982 to March 6, 2017); Chinese Biomedical Literature Database (1980 to March 20, 2017); China National Knowledge Infrastructure (1980 to March 20, 2017); VIP Information (1980 to March 20, 2017) (Chinese Database); and Wanfang Data (1980 to March 20, 2017)...

BACKGROUND: Stroke is severe complication of coronary artery bypass grafting (CABG) which may be associated with clamp strategy, there are 2 strategies to clamp aorta including single aortic clamp (SAC) and partial aortic clamp (PAC). It is controversial that which clamping strategy is better to reduce the postoperative stroke and death, so this study aims to investigate which is better for reducing postoperative stroke and death within 30 days. METHODS: We collected 469 patients who had on-pump CABG in Fuwai Hospital during January 2014 to July 2015...

BACKGROUND: The role of real-time elastography (RTE)-targeted biopsy in the detection and diagnosis of prostate cancer (PCa) remains controversial. METHODS: We searched Medline, Embase, and Cochrane Library from inception to July 31, 2017 and used the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool to assess the quality of the identified studies. We applied the relative sensitivity value to assess the diagnostic accuracy of RTE-targeted biopsy using the 10-core systematic biopsy as the reference standard...

OBJECTIVE: Several human studies have been conducted to explore the association between aspirin (ASPN) D-repeat polymorphisms and OA susceptibility, but these provide inconsistent results. Our primary aim is to examine whether D-repeat polymorphisms are related to OA risk. METHODS: We conducted a meta-analysis to investigate the association between ASPN D-repeat polymorphisms and OA. Electronic database was searched, including PubMed, Embase, CNKI, Ovid, and the reference lists of relevant articles published from the inception to January 24, 2018...

PURPOSE: Several studies have examined the potential role of p16 protein expression as a diagnostic and prognostic biomarker in various cancers. However, it remains unclear whether p16 protein expression is a prognostic and diagnostic factor for colorectal cancer. Therefore, this meta-analysis is conducted to evaluate the associations of p16 protein expression with overall survival (OS) and clinicopathological characteristics of colorectal cancer. METHODS: According to PRISMA guideline, relevant literatures were identified by searching Medicine, Web of Science, WanFang, and CNKI databases...

BACKGROUND: High-viscosity cement (HVC) has been gradually applied in percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP). Although HVC has been reported to reduce cement leakage, different opinions exist. To assess the complications of HVC in cement leakage in the treatment of vertebral compression fractures and to evaluate the clinical effect of HVC compared with low-viscosity cement (LVC). METHODS: EMBASE, PubMed, Science Direct, Google Scholar and Cochrane Library databases were comprehensively searched from their inception to August 2017...

BACKGROUND: Reduction of cyclin-dependent kinase inhibitor 2A (CDKN2A) (p16 and p14) expression through DNA methylation has been reported in prostate cancer (PCa). This meta-analysis was conducted to assess the difference of p16 and p14 methylation between PCa and different histological types of nonmalignant controls and the correlation of p16 or p14 methylation with clinicopathological features of PCa. METHODS: According to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement criteria, articles were searched in PubMed, Embase, EBSCO, Wanfang, and CNKI databases...
