BACKGROUND: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) contributes to rapid identification of pathogens in the clinic but has not yet performed especially well for Gram-positive cocci (GPC) causing complicated urinary tract infection (UTI). The goal of this study was to investigate the possible clinical use of MALDI-TOF MS as a rapid method for bacterial identification directly from urine in complicated UTI. METHODS: MALDI-TOF MS was applied to urine samples gathered from 142 suspected complicated UTI patients in 2015-2017...

Leukotrienes are proinflammatory lipid mediators that have been shown to be upregulated in several diseases, including asthma, aspirin-exacerbated respiratory disease (AERD), inflammatory bowel disease, and acute respiratory distress syndrome. Leukotrienes have been explored as therapeutic targets for these diseases and others; however, leukotriene inhibitors have had limited success in the clinic. There are noted differences in the incidence of leukotriene-mediated diseases in males and females, but sex as a factor in the response to leukotriene inhibitors has not been fully explored...

For a long time in the clinical practice the autologous nerve transplants are used in reconstruction of the segmental defects of injured hand nerves. The published outcomes, especially in case of the motor and mixed (sensory and motor) nerves, however, were not satisfactory. Hence, it remained a problem and in the focus of research. The author aimed to study this topic and drawing conclusions in his literary review publication. According to the recent results, the replacement of the autologous nerve transplants with other materials (e...

B cells are the only cell type that can give rise to antibody-producing cells, and the only cell type whose selective depletion can, today, lead to an improvement of a wide range of immune-mediated inflammatory diseases, including disorders not primarily driven by autoantibodies. Here, I discuss this paradoxical observation, and propose that the capacity of B cells to act as cytokine-producing cells explains how they can control monocyte activity and subsequently disease pathogenesis. Together with current data on the effect of anti-CD20 B cell-depleting reagents in the clinic, this novel knowledge on B cell heterogeneity opens the way for novel safer and more efficient strategies to target B cells...

Interpretation of variants of uncertain significance, especially chromosomal rearrangements in non-coding regions of the human genome, remains one of the biggest challenges in modern molecular diagnosis. To improve our understanding and interpretation of such variants, we used high-resolution three-dimensional chromosomal structural data and transcriptional regulatory information to predict position effects and their association with pathogenic phenotypes in 17 subjects with apparently balanced chromosomal abnormalities...

Stiff-knee gait (SKG) in hemiplegic patients is often due to an inappropriate activity of the quadriceps femoris. However, there are no studies in literature addressing the vastus intermedius (VI) involvement in SKG. In this study, VI activity was analyzed in a sample of 46 chronic stroke patients with SKG, during spontaneous gait. VI activity was recorded by fine-wire electrodes inserted under ultrasound guidance then confirmed by electrical stimulation. The measured VI activity was compared to the normal reference pattern reported in literature and classified (e...

OBJECTIVE: Irritable and oppositional behaviors are increasingly considered as distinct dimensions of oppositional defiant disorder. However, few studies have explored this multidimensionality across the broader spectrum of disruptive behavior problems (DBPs). This study examined the presence of dimensions and distinct subgroups of childhood DBPs, and the cross-sectional and longitudinal associations between these dimensions. METHOD: Using factor mixture models (FMMs), the presence of dimensions and subgroups of DBPs was assessed in the Generation R Study at ages 6 (n = 6,209) and 10 (n = 4,724) years...

Depression is one of the most frequent psychiatric disorders of Alzheimer's disease (AD). Depression and anxiety are associated with increased risk of developing AD. Silibinin, a flavonoid derived from milk thistle (Silybum marianum), has been used as a hepato-protectant in the clinical treatment of liver diseases. In this study, the effect of silibinin on Aβ-induced anxiety/depression-like behaviors in rats was investigated. Silibinin significantly attenuated anxiety/depression-like behaviors caused by Aβ1-42-treatment as shown in tail suspension test (TST), elevated plus maze (EPM) and forced swimming tests (FST)...

Coronary artery disease is one of the leading causes of death worldwide. The stenotic coronary vessels are generally treated with coronary artery bypass grafts (CABGs), which can be either arterial (internal mammary artery, radial artery) or venous (saphenous vein). However, the different mechanical properties of the graft can influence the outcome of the procedure in terms of risk of restenosis and subsequent graft failure. In this paper, we perform a computational fluid-structure interaction (FSI) analysis of patient-specific multiple CABGs (Y-grafts) with the aim of better understanding the influence of the choice of bypass (arterial vs venous) on the risk of graft failure...

BACKGROUND: Perforator flap techniques with conventional wound dressing have being extensively used in the management of soft-tissue defects. However; the flap's survival rate is not always guaranteed and the wound healing time always long. The aim of this study was to investigate the clinical effectiveness use of a freshly transplanted perforator flap in conjunction with Vacuum-assisted closure (VAC) for better clinical outcomes. METHODS: A prospective, randomized, effectiveness study comparing the clinical outcomes of VAC versus traditional wrap and bandages for the treatment of open wounds that required hospital admission and operative debridement using perforator flaps, was carried out from March 1, 2014 to March 31, 2016 at Wuhan University Zhongnan Hospital...
