#1
Torben Glatz, Goran Marjanovic, Jens Hoeppner
BACKGROUND: Chylothorax is a rare complication after thoracic trauma or surgery, especially oesophagectomy, which, if left untreated, can be potentially life-threatening. METHODS: This article provides an overview of the existing literature on the prevention and surgical therapy of chylothorax. RESULTS: The risk of chyle leakage after oesophagectomy increases with the difficulty of mediastinal dissection and is reported to be around 3% for oesophagectomy...

Mojgan Pourhassan, Frank Neumann
The generalized travelling salesperson problem is an important NP-hard combinatorial optimization problem for which meta-heuristics, such as local search and evolutionary algorithms, have been used very successfully. Two hierarchical approaches with different neighbourhood structures, namely a Cluster-Based approach and a Node-Based approach, have been proposed by Hu and Raidl (2008) for solving this problem. In this paper, local search algorithms and simple evolutionary algorithms based on these approaches are investigated from a theoretical perspective...

Yuwei Yang, MengMeng Zhou, Mingjun Hu, Yanjie Cui, Qi Zhong, Ling Liang, Fen Huang
BACKGROUND: Previous articles explored the role of UGT1A1 polymorphism on predicting irinotecan-induced toxicity, but the conclusions were still inconsistent and not comprehensive. We performed this meta-analysis to investigate the association between UGT1A1 polymorphism and irinotecan-induced toxicity. METHODS: PubMed and Web of Science were searched for articles before July 2017. Inclusion and exclusion criteria were set to select eligible articles, and corresponding data were extracted from those articles...

Julia Lühnen, Ingrid Mühlhauser, Anke Steckelberg
BACKGROUND: The patient's consent to a medical procedure must be preceded by a pre-procedure discussion with the physician that is documented on a standardized form. Evidence suggests that these forms lack information that would be relevant for an informed decision. METHODS: We carried out a systematic literature search up to February 2017 for evidence on the quality and efficacy of informed consent forms. The definition of criteria for the evaluation of meta-information, content, and presentation were derived from current guidelines for evidence-based health information...

#5
REVIEW
Emma A Amissah, Julie Brown, Jane E Harding
BACKGROUND: Preterm infants require high protein intake to achieve adequate growth and development. Although breast milk feeding has many benefits for this population, the protein content is highly variable, and inadequate to support rapid infant growth. This is a 2018 update of a Cochrane Review first published in 1999. OBJECTIVES: To determine whether protein-supplemented human milk compared with unsupplemented human milk, fed to preterm infants, improves growth, body composition, cardio-metabolic, and neurodevelopmental outcomes, without significant adverse effects...

REVIEW
Chloé Sarnowski, Marie-France Hivert
PURPOSE OF REVIEW: Glycated hemoglobin (A1c) is used to diagnose type 2 diabetes and monitor glycemic control. Specific genetic variants interfere with A1c and effects/frequencies of some variants vary by ancestry. In this review, we summarize findings from large trans-ethnic meta-analyses of genome-wide association studies (GWAS) of A1c and describe some variants influencing erythrocyte biology and interfering with A1c. RECENT FINDINGS: Recent GWAS meta-analyses have revealed 60 loci associated with A1c in multi-ethnic populations...

Fatty acids are among the most studied nutrients in human metabolism and health. Endogenous fatty acid status influences health and disease via multiple mechanisms at all stages of the life cycle. Despite widespread interest, attempts to summarize the results of multiple studies addressing similar fatty acid-related outcomes via meta-analyses and systematic reviews have been disappointing, largely because of heterogeneity in study design, sampling, and laboratory and data analyses. Our purpose is to recommend best practices for fatty acid clinical nutrition and medical studies...

The role of extended lymphadenectomy in the surgical treatment of gastric cancer has been debated for many years. So far six prospective randomized trials and a number of meta-analyses comparing D1 - to D2 -lymphadenectomy in open surgery have been published with contradicting results. The possible oncologic benefit of radical lymphadenectomy has been blurred by a number of reasons. In most of the trials the strategies under comparison were made similar after protocol violations. Imperfect design of the trials could not exclude the influence of cofounding factors...

Suicide is one of the public health problems worldwide, but it lacks regular relevant reporting system. This issue is more important among women who play an influential role in the family and society. Therefore, the assessment of recent relevant studies is important to detect suicide-related factors and to help make the decisions about public health. The aim of the current study was to determine socioeconomic and psychological factors of suicide attempts in Iranian women using a descriptive meta-analysis method...

Previous epidemiologic studies have revealed a possible association between microRNA-608 rs4919510 G>C polymorphism and digestive system cancers (DSCs) risk, but the results were not consistent. We therefore performed an updated meta-analysis to explore the association between microRNA-608 rs4919510 G>C polymorphism and DSCs risk. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the relationship between the microRNA-608 rs4919510 G>C polymorphism and DSCs risk. Heterogeneity, cumulative analyses, sensitivity analyses, and publication bias were also conducted to examine the statistical power...
