For two datasets, the longer inferred branch lengths sometimes impacted inference of anomaly-zone conditions. Although branch-collapsing methods did not consistently affect the species-tree topology, they often increased branch support. The more severe and clearly justified gene-tree branch-collapsing methods, which we recommend be broadly applied for two-step coalescent analyses, are use of the strict consensus in parsimony analyses and the collapse clades with 0% SH-like aLRT support in likelihood analyses. Collapsing dubiously or arbitrarily resolved branches in gene trees sometimes improved congruence between coalescent-based results and concatenation trees. In such cases, we contend that the resolution provided by concatenation should be preferred and that incomplete lineage sorting is a poor explanation for the initial conflict between phylogenetic approaches.

This study aimed to determine whether there are differences in the language used in grant applications submitted to a Southern Brazil Research Support Foundation (FAPERGS) according to the gender, career stage, and the number of publications of applicants.

This observational study also evaluated the relationship between gender, career stage, curriculum, and writing characteristics. Summaries of all research proposals in the biomedical field of FAPERGS during the years of 2013 and 2014 were evaluated according to six language patterns (Positive emotions, Negative emotions, Analytic thinking, Clout, Authenticity, and Emotional tone) defined by the LIWC software. Applicant's gender, career stage, and the number of publications were also collected.

Three hundred and forty-four (344) grant proposals met the inclusion criteria and were included in the analysis. No statistical differences were observed in the language pattern used by different gender applicants. In the language used by successful and unsuccessful applicants, we only found a small difference for clout (score 54.5 for not funded and 56.5 for funded grants). Semaxanib price However, the principal investigators of successful applications had a significantly higher number of papers published (mean number of papers 104 versus 58.5).

Gender bias appears to be a more complex problem than just the type of language used; the way society is organized causes several gender biases that may be reflected throughout the women's career.

To comprehensively describe the quality of conduct, reporting, and publication integrity characteristics for all trials included in a large Cochrane review, comparing those published by presumed predatory publishers with those published by nonpredatory publishers.

Cross-sectional meta-epidemiological study.

Two hundred seventy-nine studies (25,704 participants) eligible for the recent update of the "Exercise therapy for chronic low back pain" Cochrane review were included.

Study and manuscript characteristics, including predatory publication status and other quality and integrity characteristics were extracted along with treatment effect.

Nine percent of trials included were in presumed predatory publications; 12% in the period since 2010. We found frequency of other concerning characteristics to range from low (eg, plagiarism, 5%) to common (eg, lack of evidence of trial registration or protocol publication [75%]; insufficient sample size [84%]) in included studies. Studies published by presumed pratory publishers pose a distinct challenge to the consumption and synthesis of randomized controlled trials. More work is needed in other clinical areas to understand the potential impact of randomized controlled trials published in predatory publications, and as a result, the potential impact on evidence from systematic reviews that include these studies.This text builds on a conversation with Dr. Gordon Guyatt who provided guidance to trainees on interdisciplinary collaboration and work-life balance as part of a graduate-level biostatistics course in September 2020. The participants in the conversation comprised a group of clinicians, methodologists and biostatisticians, ranging from junior trainees to world-renowned established researchers. Biostatisticians, methodologists and clinicians often collaborate in conducting clinical research, calling upon interpersonal soft skills that are rarely explicitly addressed in undergraduate and graduate coursework. Acquiring such skills are essential for allowing seamless collaboration and communication within a multidisciplinary team and are therefore key to career advancement for young researchers, which was the focus of this session. As an invited guest, Dr. Guyatt shares his experiences after decades of leadership and successful international collaborations. He emphasizes the importance finding the right mentor, forming productive collaborations, developing self-awareness, and strategies for achieving a work-life balance.The efficacy of susceptible variants derived from genome-wide association studies (GWAs) optimizing discriminatory accuracy of colorectal cancer (CRC) in Chinese remains unclear. In the present validation study, we assessed 75 recently identified variants from GWAs. A risk predictive model combining 19 variants using the least absolute shrinkage and selection operator (LASSO) statistics offered certain clinical advantages. This model demonstrated an area under the receiver operating characteristic (AUC) of 0.61 during training analysis and yielded robust AUCs from 0.59 to 0.61 during validation analysis in three independent centers. The individuals carrying the highest quartile of risk score revealed over 2-fold risks of CRC (ranging from 2.12 to 2.90) compared with those who presented the lowest quartile of risk score. This genetic model offered the possibility of partitioning risk within the average risk population, which might serve as a first step toward developing individualized CRC prevention strategies in China.Combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is a tumour that exhibits both hepatocytic and biliary differentiation. Classical risk factors for hepatocellular carcinoma (HCC) seem to also predispose patients to the development of cHCC-CCA. The pathological definition of cHCC-CCA has significantly evolved over time. The last 2019 WHO classification highlighted that the diagnosis of cHCC-CCA should be primarily based on morphology using routine stainings, with additional immunostaining used to refine the identification of subtypes. Among them, "intermediate cell carcinoma" is recognised as a specific subtype, while "cholangiolocellular carcinoma" is now considered a subtype of iCCA. Increasing molecular evidence supports the clonal nature of cHCC-CCA and parallels its biphenotypic histological appearance, with genetic alterations that are classically observed in HCC and/or iCCA. That said, the morphological diagnosis of cHCC-CCA is still challenging for radiologists and pathologists, especially on biopsy specimens.
