COMPASS study demonstrated efficacy of dual pathway inhibition with 2.5 mg twice daily rivaroxaban and aspirin in patients with polyvascular disease (coronary artery disease, peripheral arterial disease or both), the underlying mechanism of which is not clearly understood. In this Phase IV, prospective, open-label and randomized study, we hypothesize that treatment with rivaroxaban is associated with a reduction in platelet activation and aggregation, inflammation and coagulation markers. 30 patients will be randomly treated with aspirin (81 mg q.d.) or aspirin plus rivaroxaban (2.5 mg b.i.d.) for 12 weeks. Platelet aggregation, platelet activation and inflammation markers, thrombin generation kinetics and tissue factor-induced platelet-fibrin clot strength will be measured at baseline, and 4 and 12 weeks after randomization. Trial registration number NCT04059679.Introduction Human induced pluripotent stem-cell derived cardiomyocyte (hiPSC-CM) preparations are increasingly employed in in vitro cardiac safety studies to support candidate drug selection and regulatory submissions. The value of hiPSC-CM based approaches depends on their ability to recapitulate the cellular mechanisms responsible for cardiotoxicity as well as overall assay characteristics (thus defining model performance). Different expectations at different drug development stages define the utility of these human-derived models.Areas Covered Herein, the authors review the importance of understanding the functional characteristics of the evolving spectrum of simpler (2D) and more complex (co-cultures, 3D constructs, and engineered tissues) human derived cardiac preparations, and how their performance may be evaluated based on analytical sensitivity, variability, and reproducibility in order to correctly match preparations with expectations of different safety assays. The need for consensus clinical examples of electrophysiologic, contractile, and structural cardiotoxicities essential for benchmarking human-derived models is also discussed.Expert opinion It is helpful (but not essential) that hiPSC-CMs preparations fully recapitulate pharmacological responses of native adult human ventricular myocytes when evaluating cardiotoxicity in vitro. Further calibration and model standardization (aligning concordance with clinical findings) are necessary to understand the role hiPSC-CMs in guiding cardiotoxicity assessments in early drug discovery efforts.Background The time of introduction and nutritionally adequate, safe, age-appropriate complementary feeding is extremely important for the child's optimal growth, development, and health within the first 2 years of life. Despite a number of interventions to improve infant and young child feeding practices and nutritional status, appropriate feeding practices are far away from the recommendation. Therefore, the study aimed to assess timely initiation of complementary feeding practices and associated factors among children aged 6-23 months in Gondar town, northwest Ethiopia.Methods A community-based cross-sectional study was conducted in December 2017. A multistage sampling technique was employed to select 632 mother-child pairs. Pretested structured and interviewer-administered questionnaire was used to collect data. Data were entered into Epi-info version 7 and transferred to SPSS version 20.0 for analysis. Both bivariable and multivariable logistic regression analysis were used to identify factors associated with timely initiation of complementary feeding. Finally, variables with a P-value of less then 0.05 were considered as statistically significant.Results The prevalence of timely initiation of complementary feeding was 47.3% (95%CI 43.0, 51.3). Being housewife in maternal occupation (AOR = 2.03, 95%CI 1.21, 3.43), good mother's knowledge about complementary feeding (AOR = 1.80, 95% CI 1.28, 2.53) and attending post-natal care checkup (AOR = 3.90, 95%CI 1.26, 12.04) were significantly associated with timely initiation of complementary feeding.Conclusion This study revealed that timely initiation of complementary feeding was low within the study area. Around half of the children started complementary feeding at their 6 months of age. Therefore, special emphasis should be given to mothers who have poor knowledge about complementary feeding and encourage all mothers to have postnatal follow-up is crucial.Data were collected as part of a cross-sectional study. The objectives were to compare dietary intakes of iron and enhancers and inhibitors of non-heme iron absorption in hill tribe and urban women of Chiang Rai province, northern Thailand, and compare iron- and vitamin C- containing foods sold in markets in both settings. Dietary data were collected using three 24- hour recalls from 128 women aged 19-50 years (hill tribe n = 65; urban n = 63), and proportions of low-, medium- and high-iron/vitamin C containing foods were surveyed in local markets. Hill tribe women consumed less iron, animal protein, vitamin C and calcium, but market availability of iron/vitamin C foods was similar. Future interventions should focus on food choice modification, to improve intakes of iron and foods that enhance its absorption, especially among hill tribe women.Aim Altered long noncoding RNA (lncRNA) and mRNA is vital in the progression from Helicobacter pylori (H. pylori, HP) infection to gastric cancer (GC) and mucosa-associated lymphoid tissue (MALT) lymphoma. Materials & methods Five independent Gene Expression Omnibus datasets (GSE5081, GSE84433, GSE15459, GSE66229 and GSE25638) were included in our study. Results Differentially expressed lncRNAs and mRNAs in both H. pylori-positive gastritis and GC tissues were identified. Using two GC cohorts, the H. pylori-related mRNA DYNC1I1 and MMP7 were independent predictors of overall survival. Moreover, the expressions of lncRNA GHRLOS and 44 mRNAs were significantly changed in gastric MALT lymphoma patients. Conclusion The lncRNA/mRNA response to H. pylori infection in gastritis and GC influence the outcome of GC and progression of MALT lymphoma.Adams-Oliver syndrome (AOS) is a rare hereditary disorder characterized by aplasia cutis congenita (ACC) and terminal transverse limb defects. The etiology of AOS has remained largely unknown, although mutations in the notch receptor 1 (NOTCH1) gene are most common genetic alteration associated with this disease. In this study, we aimed to identify the case of a 6-year-old boy, who presented with large ACC of the scalp and aortic valve stenosis, suggesting the possibility of AOS. Whole-exome sequencing identified a novel, de novo, in-frame deletion in the NOTCH1 gene (NOTCH1 c.1292_1294del, p.Asn431del) in the patient. find more The p.Asn431del variant was evaluated by several in silico analyses, which predicted that the mutant was likely to be pathogenic. In addition, molecular modeling with the PyMOL Molecular Graphics System suggested that the NOTCH1-N431del destabilizes calcium ion chelation, leading to decreased receptor-ligand binding efficiency. Quantitative reverse transcription PCR showed further significant downregulation of the Notch target genes, hes-related family bHLH transcription factor with YRPW motif 1 (HEY1) and hes family bHLH transcription factor 1 (HES1), suggesting that this mutation causes disease through dysregulation of the Notch signaling pathway.
