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...

BACKGROUND: Percutaneous dilatational tracheostomy (PDT) has become a standard technique for critically ill patients who require long-term ventilation. The most common early post-operative complication is bleeding related to anatomical variation in vasculature. The procedure is performed at the patient's bedside unless this is deemed unsafe and then the accepted alternative is open tracheostomy in the operating room. OBJECTIVES: To evaluate the use of pre-procedural ultrasound to aid in the decision of whether PDT in critical care patients should be performed at the patient's bedside or by open surgical tracheostomy...

A foodborne illness outbreak involving an elite sports team was investigated by a public health unit in Sydney, Australia. An epidemiological association was established between gastrointestinal illness and the consumption of food supplied by an external caterer, with a lamb meal most strongly associated with illness. Genetically identical Salmonella isolates were identified from clinical specimens, residual food items, and an environmental swab taken from the catering premises. The training schedule and other club operations were significantly affected by this outbreak...

An application of treated sewage sludge on agricultural land has been widely accepted, as this method is simple and economical for disposal of wastewater residues. When applied properly on an agricultural land, sludge can replenish organic matter and nutrients in soil. Although sewage sludge has been used in agriculture in many parts of the world, its acceptability varies with different cultures and beliefs among farmers. Farmers' concerns on sludge use are primarily due to its anthropogenic origin, pollutants that it carries, a general perception of sewage being dirty, and its offensive odor...

The aim of the present study was to determine the agreement between ultrasonography (US), magnetic resonance imaging (MRI), and conventional radiography (CR) in the detection of findings indicative of enthesopathy in spondyloarthritis (SpA) patients. A cross-sectional study was performed in 40 SpA patients. Heel entheses (Achilles tendon and plantar fascia) were bilaterally examined by US, MRI, and CR. The three imaging modalities were carried out by three independent operators blinded to the other imaging modality data...

Using an Operations Research approach, we demonstrate design of optimal trait introgression projects with respect to competing objectives. We demonstrate an innovative approach for designing Trait Introgression (TI) projects based on optimization principles from Operations Research. If the designs of TI projects are based on clear and measurable objectives, they can be translated into mathematical models with decision variables and constraints that can be translated into Pareto optimality plots associated with any arbitrary selection strategy...

In this study, zirconia-coated magnetite magnetic nanoparticles (ZrO2/Fe3O4 MNPs) were prepared, characterized, and used as an effective and reusable heterogeneous catalyst for 3,4-dichlorobenzotrifluoride (3,4-DCBTE) degradation. The catalytic potential of the Fe3O4/ZrO2-H2O2 system for the removal of 3,4-DCBTE was tested in comparison with several other systems, and the effects of various operating parameters, including initial solution pH, catalyst addition, H2O2 concentrations, and reaction temperature, were also evaluated with respect to the degradation efficiency of 3,4-DCBTE...

Determinants of persistent low-level viraemia [PLLV, a viral load (VL) of between 50 and 500 copies/mL] have not been elucidated. In a case-control study, we evaluated the influence of micronutrients on PLLV in a population of 454 HIV-1 adults having initiated antiretroviral therapy (ART) between January 2007 and December 2011. Plasma levels of retinol (vitamin A), 25-OH vitamin D2 + D3, vitamin E and zinc were measured at ART initiation in cases (PLLV after 6 months of ART) and in controls (VL <50 copies/mL after 6 months)...

PURPOSE: The German Aerospace Center (DLR) investigated in the NORAH sleep study the association between a distinct change in nocturnal aircraft noise exposure due to the introduction of a night curfew (11:00 p.m.-5:00 a.m.) at Frankfurt Airport and short-term annoyance reactions of residents in the surrounding community. Exposure-response curves were calculated by random effects logistic regression to evaluate the aircraft noise-related parameters (1) number of overflights and (2) energy equivalent noise level LASeq for the prediction of short-term annoyance...
