Objective: To assess the accuracy of computed tomographic colonography (CTC) for detection of colorectal neoplasm. Methods: Publications prior to January 2016 from the Medline, Embase, CNKI, WANFANG, and VIP literature databases were systematically reviewed. A QUADAS checklist was used to assess the quality of the studies. According to the sizes of tumor (≥6 mm or ≥10 mm), diagnostic test accuracy indexes (area under the curve, sensitivity and specific) were pooled and stratified. Spearman correlation and curve of summary receiver operating characteristic (SROC) were applied to comprehensively assess the threshold effect...

Low frequency firing is modeled by Type 1 neurons with a SNIC, but, because of the vertical slope of the square-root-like f-I curve, low f only occurs over a narrow range of I. When an adaptive current is added, however, the f-I curve is linearized, and low f occurs robustly over a large I range. Ermentrout (Neural Comput. 10(7):1721-1729, 1998) showed that this feature of adaptation paradoxically arises from the SNIC that is responsible for the vertical slope. We show, using a simplified Hindmarsh-Rose neuron with negative feedback acting directly on the adaptation current, that whereas a SNIC contributes to linearization, in practice linearization over a large interval may require strong adaptation strength...

This study aimed to assess the reliability of stroke volume variation (SVV) in predicting cardiac output (CO) decrease and hypotension during induction of general anesthesia. Forty-five patients undergoing abdominal surgery under general anesthesia were enrolled. Before induction of anesthesia, patients were required to maintain deep breathing (6-8 times/min), and pre-anesthetic SVV was measured for 1 min by electrical cardiometry. General anesthesia was induced with propofol, remifentanil, rocuronium, and sevoflurane...

Hepatocellular carcinoma (HCC) is the sixth most common cancer and the second leading cause of cancer mortality worldwide. Incidence rates of liver cancer vary widely between geographic regions and are highest in Eastern Asia and sub-Saharan Africa. In the United States, the incidence of HCC has increased since the 1980s. HCC detection at an early stage through surveillance and curative therapy has considerably improved the 5-year survival. Therefore, medical societies advocate systematic screening and surveillance of target populations at particularly high risk for developing HCC to facilitate early-stage detection...

Context • Pain from osteoarthritis is associated with peripheral nociception and central pain processing. Given the unmet need for innovative, effective, and well-tolerated therapies, many patients, after looking for more satisfactory alternatives, decide to use complementary and alternative modalities. The analgesic mechanism of subcutaneous injections of diluted bee venom into an acupoint is thought to be part of an anti-inflammatory effect and the central modulation of pain processing. Objectives • Using the rat model of collagenase-induced osteoarthritis (CIOA), the study intended to investigate the analgesic effects of bee venom acupuncture (BVA) as they are related to the acupuncture points and dosage used and to determine whether the analgesic mechanisms of BVA for pain were mediated by opioid or adrenergic receptors...

BACKGROUND: Antihypertension medication (antihypertensive) adherence lowers risk of cardiovascular disease (CVD); few studies have examined this association among older adults. METHODS AND RESULTS: We assessed this association among Medicare fee-for-service beneficiaries aged 66 to 79 years who were newly diagnosed with hypertension and initiated on antihypertensives in 2008-2009 (n=155 597). We calculated proportion of days covered (PDC) during follow-up, using proportional subdistribution hazard models, to examine association between antihypertensive adherence and a composite CVD outcomes, including first incident of fatal/nonfatal acute myocardial infarction, ischemic heart disease, stroke/transient ischemic attack, and heart failure...

Insufficient temporal monitoring of water quality in streams or engineered drains alters the apparent shape of storm chemographs, resulting in shifted model parameterisations and changed interpretations of solute sources that have produced episodes of poor water quality. This so-called 'aliasing' phenomenon is poorly recognised in water research. Using advances in in-situ sensor technology it is now possible to monitor sufficiently frequently to avoid the onset of aliasing. A systems modelling procedure is presented allowing objective identification of sampling rates needed to avoid aliasing within strongly rainfall-driven chemical dynamics...

BACKGROUND: As the number of transcatheter aortic valve implantation (TAVI) procedures is constantly increasing, it is important to consider common complications, such as pacemaker (PM) implantation, and their specific risk factors. AIMS: Echocardiographic, computed tomography and electrocardiographic data were analysed to determine the predicting factors, if any, associated with PM implantation. METHODS: This retrospective study included patients referred to Nancy University Hospital for a TAVI procedure from January 2013 to December 2015...

BACKGROUND: Deterministic diffusion tractography obtained from high angular resolution diffusion imaging (HARDI) requires user-defined quantitative anisotropy (QA) thresholds. Most studies employ a common threshold across all subjects even though there is a strong degree of individual variation within groups. We sought to explore whether it would be beneficial to use individual thresholds in order to accommodate individual variance. To do this, we conducted two independent experiments...

Bovine mastitis is an important disease in the dairy industry, causing economic losses as a result of withheld milk and treatment costs. Several studies have suggested milk amyloid A (MAA) as a promising biomarker in the diagnosis of mastitis. In the absence of a gold standard for diagnosis of subclinical mastitis, we estimated the diagnostic test accuracy of a commercial MAA-ELISA, somatic cell count (SCC), and bacteriological culture using Bayesian latent class modeling. We divided intramammary infections into 2 classes: those caused by major pathogens (e...

REVIEW
David C Spray, Menachem Hanani
Enhanced expression and function of gap junctions and pannexin (Panx) channels has been associated with both peripheral and central mechanisms of pain sensitization. At the level of the sensory ganglia, evidence includes augmented gap junction and pannexin1 expression in glial cells and neurons in inflammatory and neuropathic pain models and increased synchrony and enhanced cross-excitation among sensory neurons by gap junction-mediated coupling. In spinal cord and in suprapinal areas, evidence is largely limited to increased expression of relevant proteins, although in several rodent pain models, hypersensitivity is reduced by treatment with gap junction/Panx1 channel blocking compounds...

OBJECTIVE: Digital subtraction angiography (DSA) of the peripheral arterial vasculature provides lumenographic information but only a qualitative assessment of blood flow. The ability to quantify adequate tissue perfusion of the lower extremities would enable real-time perfusion assessment during DSA of patients with peripheral arterial disease (PAD). In this study, we used a novel real-time imaging software to delineate tissue perfusion parameters in the foot in PAD patients. METHODS: Between March 2015 and June 2016, patients (N = 31) underwent lower extremity angiography using a two-dimensional perfusion (2DP) imaging protocol (Philips Healthcare, Andover, Mass)...

Unlicensed and off-label (UL/OL) drugs are commonly used in pediatrics wards, especially the antibiotics. It remains unclear if this strategy is justified by randomized controlled trials of good quality? OBJECTIVE: The aim of this study was to compare the level of evidence of UL/OL antibiotics prescription in hospitalized children. The initial hypothesis was that the UL/OL antibiotics prescriptions had a lower level of evidence than licensed antibiotics. METHOD: This observational study assessed the antibiotics prescription in the children mother and women hospital of Lyon...

REVIEW
Benjamin D Kozower, George J Stukenborg
Most thoracic surgery studies indicate that hospital and surgeon procedure volume are inversely associated with mortality. However, controversy exists regarding the strength and validity of this volume-outcome association. Because thresholds of procedure volume are used to recommend the regionalization of care, investigation of the volume-outcome relationship is imperative. This article examines the methodology used in the volume-outcome relationship literature and highlights important areas of concern. Careful examination of the literature demonstrates that lung and esophageal cancer resection volume is not strongly associated with mortality and should not be used as a proxy measure for quality...

BACKGROUND: Epidemics of meningococcal meningitis are common in the "African meningitis belt." Current response strategies include reactive vaccination campaigns, which are often organized too late to have maximal impact. A novel strain of Neisseria meningitidis serogroup C has been circulating in recent years, and vaccine supplies are limited. An evaluation of chemoprophylaxis with single-dose ciprofloxacin for household contacts of meningitis cases has therefore been recommended. METHODS/DESIGN: A three-arm cluster-randomized trial has been designed for implementation during a meningococcal meningitis epidemic in a health district in Niger in which at least two Health Zones (HZs) have met the weekly epidemic threshold...

BACKGROUND: Lowering cholesterol levels decreases the risk of atherosclerotic diseases. Effective ways to stably reduce LDL-C level are warranted in type 2 diabetic patients, a high-risk population for CVD, with various anti-diabetic therapeutic background. The RESEARCH study focuses on LDL-C reduction in this population along with modifications of the lipid profiles. We evaluated long-term ezetimibe add-on therapy in T2DM patients with hypercholesterolemia. METHODS: In a randomized, multicenter, open-label, prospective study, a total of 109 T2DM patients not attaining LDL-C target value despite first-line dose statin (10 mg of atorvastatin or 1 mg of pitavastatin) therapy in Japan were recruited...

The metal(loid) pollution still is a great concern due to the effects from urbanization and industrialization. While, the health risks from the toxic metal(loid)s could decrease if strict pollution control measures were adopted. However, few studies to date investigate the health risks of heavy metal(loid)s in a systematic river basin for the dependent residents, after taking pollution control measures. Thus, the contents of metal(loid)s (Cu, Pb, Zn, Cd, Mn, As) in surface water along a typical river basin were investigated in this study, and the potential non-carcinogenic and carcinogenic health risks posed to the residents were assessed...
