This systematic review (PROSPERO - CRD42020150722) was performed to answer the following question Does the use of chelating agents affect the dislodgment resistance of epoxy resin-based root canal sealers? A search was conducted in PubMed, EMBASE, Scopus, LILACS and Web of Science, hand searching of two endodontic journals and grey literature until September 2020. Extracted data included teeth used, sample size, root canal preparation, irrigant, chelating solution, neutralisation solution, type of resin-based sealer and obturation approach, storage method and duration, root third and slice thickness, plunger dimension and loading direction and the push-out testing parameters and values. The search retrieved a total of 2.389 studies. After analysis, 12 studies fulfilled the eligibility criteria and were included. Most of the final irrigation protocols with chelating agents had a positive impact and promoted an improvement in the dislodgment resistance of epoxy resin-based sealers to the root dentin.
To systematically review current practices, strengths, and limitations of existing VA approaches to increase their understanding by health information systems stakeholders and researchers.

The review was conducted and reported based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, in which articles were systematically obtained from the PubMed and SCOPUS online databases. The search was limited to English language journal articles published between 2010 and 2020. The review identified 5602 articles and after thorough scrutiny, 25 articles related to VA approaches were included.

(1) InterVA and Tariff are widely used VA models; (2) Bayes rule is the most common and successful algorithm; (3) the lack of standardized datasets and metrics to evaluate models creates bias in determining VA model performance; (4) performance of the models trained using in-hospital data cannot be replicated in community death; (5) the performance of models among physicians and computt settings.Studies have demonstrated that small interfering RNA (siRNA) targeting YKL-40 (siYKL-40) inhibits the proliferation, migration, invasion and induces anti-apoptotic abilities of endometrial cancer (EC) HEC-1A cells. However, its effect on angiogenesis is unclear. The present study aimed to investigate the role of YKL-40 in endometrial cancer and the related molecular mechanisms. YKL-40 was knocked down by transfection with siYKL-40 and the effects on angiogenesis, cell viability and signaling pathways were investigated. The results showed that siYKL-40 inhibited VEGFA levels and tube formation in endothelial cells. Additionally, inhibition of YKL-40 decreased the expression levels of vascular endothelial growth factor (VEGF), phosphorylated vascular endothelial growth factor receptor 2 (pVEGFR2) and phosphorylated extracellular signal-regulated kinases 1 and 2 (pERK1/2). Furthermore, a nude mice xenograft model of EC showed that siYKL-40 inhibited tumor growth. Inhibition of YKL-40 led to suppression of angiogenesis and reduction of microvessel density through VEGF/VEGFR2 and ERK1/2 signaling in endometrial cancer cells. Taken together, this study demonstrated novel molecular mechanisms for role of YKL-40 in EC. This article is protected by copyright. All rights reserved.
Publications provide important information for clinicians, researchers, and patients. Key methodological elements must be reported for maximum transparency. We identified key methodological elements necessary for fully understanding perinatal pharmacoepidemiology research and quantified the proportion of studies that reported these elements in a sample of publications.

Key methodological elements were identified from guidelines from regulatory agencies, literature, and subject-matter knowledge source of information to determine pregnancy start; mother- or father-infant linkages (process, success rate); unit of analysis; and whether non-live births and fetuses with various anomalies were included in the study population. We conducted a literature review for recent observational studies on medical product utilization or safety during pregnancy and estimated the prevalence of reporting these elements.

Data were extracted from a random sample of 100 publications; 8% were published in epidemiology/pharmacoepcy-specific checklist would increase transparency in the dissemination of study results.Schizophrenia is associated with widespread alterations in subcortical brain structure. While analytic methods have enabled more detailed morphometric characterization, findings are often equivocal. In this meta-analysis, we employed the harmonized ENIGMA shape analysis protocols to collaboratively investigate subcortical brain structure shape differences between individuals with schizophrenia and healthy control participants. The study analyzed data from 2,833 individuals with schizophrenia and 3,929 healthy control participants contributed by 21 worldwide research groups participating in the ENIGMA Schizophrenia Working Group. Harmonized shape analysis protocols were applied to each site's data independently for bilateral hippocampus, amygdala, caudate, accumbens, putamen, pallidum, and thalamus obtained from T1-weighted structural MRI scans. Mass univariate meta-analyses revealed more-concave-than-convex shape differences in the hippocampus, amygdala, accumbens, and thalamus in individuals with schizophrenia compared with control participants, more-convex-than-concave shape differences in the putamen and pallidum, and both concave and convex shape differences in the caudate. Patterns of exaggerated asymmetry were observed across the hippocampus, amygdala, and thalamus in individuals with schizophrenia compared to control participants, while diminished asymmetry encompassed ventral striatum and ventral and dorsal thalamus. Our analyses also revealed that higher chlorpromazine dose equivalents and increased positive symptom levels were associated with patterns of contiguous convex shape differences across multiple subcortical structures. Findings from our shape meta-analysis suggest that common neurobiological mechanisms may contribute to gray matter reduction across multiple subcortical regions, thus enhancing our understanding of the nature of network disorganization in schizophrenia.
To find out the adherence to lifestyle modifications and its associated factors in hypertensive patients.

Low adherence to lifestyle modifications leads to poor therapeutic effectiveness, decreased quality of life, poor health outcomes and increased health care costs. Various factors play an important role in determining the adherence level varying among the different cultural, social and national contexts.

A cross-sectional analytical research design was carried out.

Information from 264 patients with hypertension was collected at the Outpatient Department of Manmohan Cardiothoracic, Vascular and Transplant Center, Kathmandu. AGI-6780 A standard tool of WHO Steps Survey Questionnaire and Hypertension Fact Questionnaire was used for data collection. Chi-square test and binary logistic regression were used for analysis using SPSS 16.

The overall adherence to lifestyle modifications was determined as 20.8% with the adherence rate being lowest up to 30.3% for adequate intake of fruits and vegetables. Likewise, g the hypertensive patients.
Nurses are frequently acquainted with the hypertensive patients in hospitals where they need to provide health teaching on lifestyle modifications. This study identifies the factors that need to be considered while counselling the hypertensive patients.
To describe nurses and ward managers' experiences with nursing leadership in the implementation of evidence-based practice.

The implementation of evidence-based practice requires to identify the most suitable styles of nursing leadership for the successful application.

A qualitative descriptive study.

The study was carried out with 57 nurses (clinical nurses and ward managers) in eight focus groups from five public hospitals. Template analysis, using the Promoting Action on Research Implementation in Health Services framework, was used. The Consolidated Criteria for Reporting Qualitative Research guide was followed in planning and reporting this research.

Three types of nursing leadership were identified traditional leadership, medium leadership, and transformational leadership. Traditional leadership was the most frequent, with a predominance of bureaucratic tasks for ward managers, so implementation of evidence-based practice is difficult.

Nurses do not feel empowered and they perceive the changes as an imposition. In the absence of strong leadership for evidence-based practice, a natural leader emerges.

Clinical nurses demand more empowerment for decision making and ward managers need clarity of roles. To create an environment favourable to evidence-based practice, it is necessary consider the role of the transformational leader.

This was certainly true for the eukaryote-infecting circular Rep (replication-associated protein)-encoding single-stranded DNA (CRESS DNA) viruses, which were thought to be a relatively small group of viruses. With the explosion of metagenomic sequencing over the past decade and increasing use of rolling-circle replication for sequence amplification, scientists have identified and annotated copious numbers of novel CRESS DNA viruses - many without known hosts but which have been found in association with eukaryotes. Similar advances in cellular genomics have revealed that many eukaryotes have endogenous sequences homologous to viral Reps, which not only provide 'fossil records' to reconstruct the evolutionary history of CRESS DNA viruses but also reveal potential host species for viruses known by their sequences alone. The Rep protein is a conserved protein that all CRESS DNA viruses use to assist rolling-circle replication that is known to be endogenized in a few eukaryotic species (notably tobacco and water yam). link3 A systematic search for endogenous Rep-like sequences in GenBank's non-redundant eukaryotic database was performed using tBLASTn. We utilized relaxed search criteria for the capture of integrated Rep sequence within eukaryotic genomes, identifying 93 unique species with an endogenized fragment of Rep in their nuclear, plasmid (one species), mitochondrial (six species) or chloroplast (eight species) genomes. These species come from 19 different phyla, scattered across the eukaryotic tree of life. Exogenous and endogenous CRESS DNA viral Rep tree topology suggested potential hosts for one family of uncharacterized viruses and supports a primarily fungal host range for genomoviruses.We examined the impact of primary care physician density on perinatal health outcomes in Norway. From 1992 and onwards, primary care physicians who chose to work in selected remote municipalities were given an annual reduction in their student loan. This reduction, combined with increased supply of physicians, led to an increase in the density of primary care physicians in these selected municipalities. Our register-based population study showed that this increase in physician density significantly improved perinatal health in terms of fewer fetal deaths and increased birth weight. The richness of the data allowed us to perform several robustness tests.
