The clinical benefits of perioperative antioxidant vitamin therapy in cardiac patients remain controversial. Here, we conducted a meta-analysis to determine the strength of the evidence supporting the perioperative use of antioxidant vitamins in patients undergoing cardiac surgery. We searched 4 databases (PubMed, EMBASE, Science Citation Index and Cochrane Library) for randomized controlled trials that reported the effects of antioxidant vitamin therapy on patients undergoing cardiac surgery until 6 June 2016...

Quantitative evaluation of the microstructural state of a specimen can be deduced from knowledge of the sample's absolute acoustic nonlinearity parameter, β, making the measurement of β a powerful tool in the NDE toolbox. However, the various methods used in the past to measure β each suffer from significant limitations. Piezoelectric contact transducers are sensitive to nonlinear signals, cheap, and simple to use, but they are hindered by the variability of the interfacial contact between transducer and specimen surface...

BACKGROUND: There has been recent interest in wide awake hand surgery, also referred to as "wide awake local anesthesia with no tourniquet" (WALANT) surgery. Using a model of single trigger finger release (TFR) surgery, a hypothesis was made that WALANT would result in decreased hospital time and cost than patients receiving sedation with monitored anesthetic care (MAC). METHODS: Consecutive cases of single TFR surgery with MAC were compared with WALANT. All surgeries were performed in the same manner, at the same facility, and by the same surgeon...

Network models, in which psychopathological disorders are conceptualized as a complex interplay of psychological and biological components, have become increasingly popular in the recent psychopathological literature (Borsboom, et. al., 2011). These network models often contain significant numbers of unknown parameters, yet the sample sizes available in psychological research are limited. As such, general assumptions about the true network are introduced to reduce the number of free parameters. Incorporating these assumptions, however, means that the resulting network will lead to reflect the particular structure assumed by the estimation method-a crucial and often ignored aspect of psychopathological networks...

BACKGROUND: Pain complaints are common, but clinicians are increasingly concerned about overuse of opioid pain medications. This may lead patients with actual pain to be stigmatized as "drug-seeking," or attempting to obtain medications they do not require medically. We assessed whether patient requests for specific opioid pain medication would lead physicians to classify them as drug-seeking and change management decisions. METHODS AND FINDINGS: Mixed-methods analysis of interviews with 192 office-based primary care physicians after viewing video vignettes depicting patients presenting with back pain...

The majority of studies on parent-child discrepancies in the assessment of adolescent emotional and behavioral problems have been conducted in Western countries. It is believed that parent-adolescent agreement would be higher in societies with a strong culture of familism. We examined whether parent-adolescent discrepancies in the rating of adolescent emotional and behavioral problems are related to parental and family factors in Taiwan. Participants included 1,421 child-parent pairs of 7th-grade students from 12 middle schools in Northern Taiwan and their parents...

Concerns regarding lead (Pb) poisoning in French Guiana first arose in 2011 following the discovery of excessively high levels of the metal amongst children in a small neighborhood without any apparent source of Pb. Since 2012, blood lead level (BLL) measurement has been proposed for all pregnant women in western French Guiana. The aim of this study was to determine BLL in pregnant women in this region and identify factors associated with elevated BLL. An observational study of a consecutive sample of women who delivered in the maternity ward of the hospital was conducted...

This study investigated factors associated with acute stress symptoms in parents of seriously ill children across a range of illnesses and treatment settings within a pediatric hospital setting. It was hypothesized that psychosocial variables would be more strongly associated with acute stress responses than demographic and child illness variables. Participants were 115 mothers and 56 fathers of children treated within the oncology, cardiology, and intensive care departments of a pediatric hospital. Acute stress, psychosocial, demographic, and medical data were collected within the first 4 weeks of the child's hospital admission...

Parenchymal transection during hepatobiliary surgery can disrupt small vasculature or bile ducts, which could be managed difficultly. Sealants are helpful tools to achieve better hemostasis. The aim of this study is to analyze the hemostatic efficiency of four modern sealants in a porcine model. In this study, 40 landrace pigs were assigned equally to the control (without sealant) and four sealant groups. Standardized liver resection and splenic lesions were performed and left without using sealant (control) or treated with one of the following sealants: TachoSil(®) , Tissucol Duo(®) , Coseal(®) , and FloSeal(®) ...

OBJECTIVE Blood loss and moderate anemia are common in patients with traumatic brain injury (TBI). However, despite evidence of the ill effects and expense of the transfusion of packed red blood cells, restrictive transfusion practices have not been universally adopted for patients with TBI. At a Level I trauma center, the authors compared patients with TBI who were managed with a restrictive (target hemoglobin level > 7 g/dl) versus a liberal (target hemoglobin level > 10 g/dl) transfusion protocol. This study evaluated the safety and cost-efficiency of a hospital-wide change to a restrictive transfusion protocol...

BACKGROUND: Colorectal cancer (CRC) is the third most common cancer in the UK. Presenting symptoms that can be associated with CRC usually have another explanation. Faecal immunochemical tests (FITs) detect blood that is not visible to the naked eye and may help to select patients who are likely to benefit from further investigation. OBJECTIVES: To assess the effectiveness of FITs [OC-Sensor (Eiken Chemical Co./MAST Diagnostics, Tokyo, Japan), HM-JACKarc (Kyowa Medex/Alpha Laboratories Ltd, Tokyo, Japan), FOB Gold (Sentinel/Sysmex, Sentinel Diagnostics, Milan, Italy), RIDASCREEN Hb or RIDASCREEN Hb/Hp complex (R-Biopharm, Darmstadt, Germany)] for primary care triage of people with low-risk symptoms...
