OBJECTIVES: The validity of outcomes of systematic reviews is highly dependent on the extent of bias in the included primary studies. This study reports the risk of bias of primary studies included in systematic reviews of diagnostic accuracy. STUDY DESIGN AND SETTING: All systematic reviews of diagnostic accuracy studies published in the Cochrane database in 2015 and 2016 that used the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) risk of bias (ROB) tool, and reported results with the ROB figure were eligible...

AIMS: The aims of the current study were to characterise the outer membrane proteins (OMPs) of Francisella noatunensis subsp. orientalis (Fno) STIR-GUS-F2f7, and identify proteins recognised by sera from tilapia, Oreochromis niloticus, (L) that survived experimental challenge with Fno. METHODS AND RESULTS: The composition of the OMPs of a virulent strain of Fno (STIR-GUS- F2f7), isolated from diseased red Nile tilapia in UK, was examined. The sarcosine-insoluble OMP fraction was screened with tilapia hyper-immune sera by western blot analysis following separation of the proteins by 1D SDS-PAGE...

Pediatric HSCT recipients are at high risk for CMV reactivation due to their immature immune system and therapy following transplantation. Reconstitution of CMV-specific T-cell immunity is associated with control and protection against CMV. The clinical utility of monitoring CMV-specific CMI to predict CMV viremia in pediatric HSCT patients using the Quantiferon-CMV (QIAGEN® ) test was investigated prospectively. Thirty-seven pediatric allogeneic HSCT recipients were enrolled from 3/2010-6/2012. CMV viremia was detected via weekly real-time PCR...

Turner syndrome (TS) is a common genetic disorder in females with high incidence of ascending aortic dilatation and even dissection occurring as early as in the second decade. Known risk factors (RF) are bicuspid aortic valves (BAV), coarctation of the aorta (CoA), and arterial hypertension. Since 10% of dissections occur in patients without RF, an intrinsic aortic wall abnormality has been postulated. This study aimed to investigate the elasticity of the ascending aorta as a surrogate marker of aortic wall texture...

OBJECTIVES: Malocclusions affect about two-thirds of the population and orthodontic treatment is justified in 65% of these. However, the associations between anterior and posterior occlusal plane (AOP, POP) inclinations and Angle classification are lacking. PATIENTS AND METHODS: In a retrospective study, lateral cephalometric radiograph tracings of 230 previously untreated Caucasians, aged 13 to 49 years, yielded inclines of the bisector occlusal plane, AOP, and POP...

BACKGROUND/OBJECTIVES: Dietary carbohydrate quality and quantity fluctuate but it is unknown which attribute takes precedence in vascular health preservation. We investigated all four permutations of glycemic index (GI) and glycemic load (GL) on acute vascular and glycemic responses. SUBJECTS/METHODS: Twenty-one healthy adults were screened for this crossover trial. Seventeen (8 M:9 F; 26.7 ± 12.3 y; BMI 22.2 ± 2.8 kg/m2 ) entered randomization and completed the study, receiving four isocaloric meals, varying in GI and GL, in random order at least 3 days apart...

BACKGROUND: Since the introduction of National Institute for Health and Care Excellence glaucoma guidelines 2009, the number of referrals from community optometrists to hospital eye services has increased across the UK, resulting in increase in first visit discharge rates (FVDRs). AIM: To assess the impact of Scottish Intercollegiate Guidelines Network (SIGN) 144 on quality of referrals from community optometrists. METHODOLOGY: A retrospective study of patient records who attended as new adult glaucoma referrals to clinics in Princess Alexandra Eye Pavilion, Edinburgh, and in Greater Glasgow and Clyde, was carried out across October-November 2014 (group 1) and September-October 2016 (group 2), before and after the introduction of SIGN 144...

Background Interstitial fibrosis is associated with chronic renal failure. In addition to fibroblasts, bone marrow-derived cells and tubular epithelial cells have the capacity to produce collagen. However, the amount of collagen produced by each of these cell types and the relevance of fibrosis to renal function are unclear. Methods We generated conditional cell type-specific collagen I knockout mice and used (reversible) unilateral ureteral obstruction and adenine-induced nephropathy to study renal fibrosis and function...

Small cell lung cancer (SCLC) represents the most aggressive pulmonary neoplasm and is often diagnosed at late stage with limited survival, despite combined chemotherapies. We show in an autochthonous mouse model of SCLC that combined anti-VEGF/anti-PD-L1 targeted therapy synergistically improves treatment outcome compared to anti-PD-L1 and anti-VEGF monotherapy. Mice treated with anti-PD-L1 alone relapsed after 3 weeks and were associated with a tumor-associated PD-1/TIM-3 double positive exhausted T cell phenotype...

INTRODUCTION: Return to work (RTW) after breast cancer (BC) is still a new field of research. The factors determining shorter sick leave duration of patients with BC have not been clearly identified. The aim of this study was to describe work during BC treatment and to identify factors associated with sick leave duration. MATERIALS AND METHODS: An observational, prospective, multicentre study was conducted among women with operable BC. A logbook was given to all working patients to record sociodemographic and work-related data over a 1-year period...

BACKGROUND: Faced with patients suffering from more than one chronic condition, or multimorbidity, general practitioners (GPs) must establish diagnostic and treatment priorities. Patients also set their own priorities to handle the everyday burdens associated with their multimorbidity and these may be different from the priorities established by their GP. A shared patient-GP agenda, driven by knowledge of each other's priorities, would seem central to managing patients with multimorbidity...

BACKGROUND: Over the last decade, a wide range of attention-deficit/hyperactivity disorder (ADHD) treatment approaches for adults, including both pharmacological interventions and psychosocial treatments, have been proposed and observed to be efficient. In practice, individual treatment concepts are based on results of clinical studies as well as international guidelines (NICE Guidelines) that recommend a step-by-step treatment approach. Since the evidence supporting this approach is limited, the aim of the present study is to determine an optimal intervention regarding severity levels of ADHD symptomatology conducting a randomized controlled trial...

BACKGROUND: We hypothesise that a comprehensive optical coherence tomography (OCT)-guided implantation protocol for bioresorbable scaffolds (BRS) might improve expansion and apposition, thus translating into better clinical outcomes, particularly reducing thrombotic events. METHODS: Patients considered suitable for BRS therapy in de novo coronary lesions underwent OCT. The predominant type of plaque was classified as lipidic, fibrous or calcific, undergoing tailored plaque preparation accordingly...

The extreme rate of evaporation of the Dead Sea (DS) has serious implicatios for the surrounding area, including atmospheric conditions. This study analyzes the aerosol properties over the western and eastern parts of the DS during the year 2013, using MAIAC (Multi-Angle Implementation of Atmospheric Correction) for MODIS, which retrieves aerosol optical depth (AOD) data at a resolution of 1km. The main goal of the study is to evaluate MAIAC over the study area and determine, for the first time, the prevailing aerosol spatial patterns...

The proto-oncogene Akt/protein kinase B (PKB) is a pivotal signal transducer for growth and survival. Growth factor stimulation leads to Akt phosphorylation at two regulatory sites (Thr308, Ser473), acutely activating Akt signaling. Delineating the exact role of each regulatory site is, however, technically challenging and has remained elusive. Here, we used genetic code expansion to produce site-specifically phosphorylated Akt1 in order to dissect the contribution of each regulatory site to Akt1 activity. We achieved recombinant production of full length Akt1 containing site-specific pThr and pSer residues for the first time...

BACKGROUND: The prevalence of primary monosymptomatic nocturnal enuresis (PMNE) has a range of 1.6-5.3% in adolescents and 7.5-12.4% in children of 5-10 years. Alarm intervention has been well known for more than 30 years. This method is a reliable and safe means of treating primary monosymptomatic nocturnal enuresis, being effective in 60-80% of cases. OBJECTIVE: The objective of this study was to determine the efficacy of alarm intervention prolongation after the cure in order to reduce the risk of disease recurrence...

INTRODUCTION: Sleep quality relates to mental health in clinical and non-clinical populations. However, there is more evidence of this relationship in clinical populations. Therefore, there is lack of evidence on how these variables relate and on which sociodemographic factors influence this relationship in non-clinical populations. In this study we hypothesize that in a non-clinical population sleep quality predicts mental health indicators and that age, country and gender moderate this relationship...
