BACKGROUND: Recent short-term clinical trials in patients with Duchenne Muscular Dystrophy (DMD) have indicated greater disease variability in terms of progression than expected. In addition, as average life-expectancy increases, reliable data is required on clinical progression in the older DMD population. OBJECTIVE: To determine the effects of corticosteroids on major clinical outcomes of DMD in a large multinational cohort of genetically confirmed DMD patients...

Fluoroquinolones (FQ) are potential treatments to treat infections from extended-spectrum β-lactamase producing-Enterobacteriaceae susceptible to FQ. Due to increasing non-susceptibility to carbapenems among Enterobacteriaceae, we characterized FQ resistance mechanisms in 36 Klebsiella pneumoniae isolates that are non-susceptible to ertapenem in North-Eastern France in 2012 and described the population structure by pulsed field gel electrophoresis (PFGE) and multi-locus sequence typing (MLST). Among them, 36% (13/36) carried a carbapenemase encoding-gene...

Transcatheter aortic valve implantation shortcomings such as relevant paravalvular leakage (PVL) have been shown to negatively impact survival. The Sapien 3 prosthesis has added features to address these problems. We compared the functional performance of the Sapien 3 (S3) and its predecessor Sapien XT (XT), with a particular focus on PVL. We analyzed 601 patients presenting with severe native aortic valve stenosis treated with either Sapien XT (n = 405, 2011 to 2014, mean STS-PROM [Society of Thoracic Surgeons predicted risk of mortality] 11...

Immune checkpoint inhibitors (ICI) targeting the PD-1/PD-L1 axis induce sustained clinical responses in a sizeable minority of cancer patients. Here, we show that primary resistance to ICI can be due to abnormal gut microbiome composition. Antibiotics (ATB) inhibited the clinical benefit of ICI in patients with advanced cancer. Fecal microbiota transplantation (FMT) from cancer patients who responded to ICI (but not from non-responding patients) into germ-free or ATB-treated mice ameliorated the antitumor effects of PD-1 blockade...

Primary renal tubulointerstitial disease resulting from proximal tubule antigen-specific antibodies and immune complex formation has not been well characterized in humans. We report a cohort of patients with a distinct, underappreciated kidney disease characterized by kidney antibrush border antibodies and renal failure (ABBA disease). We identified ten patients with ABBA disease who had a combination of proximal tubule damage, IgG-positive immune deposits in the tubular basement membrane, and circulating antibodies reactive with normal human kidney proximal tubular brush border...

REVIEW

Recent biochemical observations have helped redefine antigenic components within the voltage-gated potassium channel (VGKC) complex. The related autoantibodies may be now divided into likely pathogenic entities, which target the extracellular domains of leucine-rich glioma-inactivated 1 (LGI1) and contactin-associated protein-like 2 (CASPR2), and species that target intracellular neuronal components and are likely non-pathogenic. This distinction has enhanced clinical practice as direct determination of LGI1 and CASPR2 antibodies offers optimal sensitivity and specificity...

Early metastatic dissemination and evolution of disseminated cancer cells (DCCs) outside the primary tumor is one reason for the failure of adjuvant therapies because it generates molecular geno- and phenotypes different from primary tumors which still underlie therapy decisions. Since ERBB2 amplification in esophageal DCCs but not in primary tumor cells predict outcome, we aimed to establish an assay with diagnostic reliability for single DCCs or circulating tumor cells (CTCs). For this we evaluated copy number alterations of more than 600 single DCCs from multiple cancer types to define reference regions suitable for quantification of target regions, such as ERBB2...

The United Nations Convention on the Rights of the Child not only grants comprehensive rights to children via international law, it also constitutes a legally binding framework under German federal law. With respect to health care, the convention establishes the "right of the child to the enjoyment of the highest attainable standard of health" and the principle that "the best interests of the child shall be a primary consideration" in all actions undertaken by public or private institutions. Here, some fundamental aspects of the convention and the monitoring of its implementation are summarized and current challenges in paediatric medicine in Germany are discussed in light of the convention...

NMR is a widely used analytical technique with a growing number of repositories available. As a result, demands for a vendor-agnostic, open data format for long-term archiving of NMR data have emerged with the aim to ease and encourage sharing, comparison and reuse of NMR data. Here we present nmrML, an open XML-based exchange and storage format for NMR spectral data. The nmrML format is intended to be fully compatible with existing NMR data for chemical, biochemical and metabolomics experiments. nmrML can capture raw NMR data, spectral data acquisition parameters and, where available, spectral metadata such as chemical structures associated with spectral assignments...

BACKGROUND: IL10 receptor (IL10R) deficiency causes severe infantile-onset inflammatory bowel disease. Intact IL10R-dependent signals have been shown to be important for innate and adaptive immune cell functions in mice. We have previously reported a key role of IL10 in the generation and function of human anti-inflammatory macrophages. Independent of innate immune cell defects, the aim of the current study was to determine the role of IL10R signaling in regulating human CD4 T-cell function...

Context: Fibroblast growth factor (FGF)19 and FGF21 are secreted by the intestine and liver in response to macronutrient intake. Intestinal resection and reconstruction via bariatric surgery may alter their regulation. Objective: We tested the hypothesis that weight loss induced by Roux-en-Y gastric bypass (RYGB) surgery, but not matched weight loss induced by laparoscopic adjustable gastric banding (LAGB), increases postprandial plasma FGF19 and FGF21 concentrations...

Poly(acrylic acid)-based hydrogels can swell up to 100-1000 times their own weight in desalinated water due to osmotic forces. As the swelling is about a factor of 2-12 lower in seawater-like saline solutions (4.3 wt% NaCl) than in deionized water, cyclic swelling, and shrinking can potentially be used to move a piston in an osmotic motor. Consequently, chemical energy is translated into mechanical energy. This conversion is driven by differences in chemical potential and by changes in entropy. This is special, as most thermodynamic engines rely instead on the conversion of heat into mechanical energy...

BACKGROUND: In contrast to adult-onset inflammatory bowel disease (IBD), where many genetic loci have been shown to be involved in complex disease etiology, early-onset IBD (eoIBD) and associated syndromes can sometimes present as monogenic conditions. As a result, the clinical phenotype and ideal disease management in these patients often differ from those in adult-onset IBD. However, due to high costs and the complexity of data analysis, high-throughput screening for genetic causes has not yet become a standard part of the diagnostic work-up of eoIBD patients...

Fibroblasts of a 28-year-old female with Marfan syndrome (MFS) due to a heterozygous FBN1 c.4082G>A mutation were reprogrammed using the Sendai virus delivery method. The established human induced pluripotent stem cell (hiPSC) line named ISMMSi002-B expresses pluripotency markers, has a normal karyotype, carries the specific FBN1 mutation and is able to differentiate into three germ layers in vitro. ISMMSi002-B has utility in studying MFS pathogenesis, including skeletal abnormalities, cardiomyopathy, and vascular smooth muscle cell dysfunction associated with aortic aneurysm...
