Phylogenomic approaches now generate hundreds of loci representative of the whole genome that can be used for phylogenetic analyses. The South American lizard genus Liolaemus is the most species-rich vertebrate radiation from temperate zones (more than 265 described species), yet most higher-level phylogenetic relationships within Liolaemus remain poorly resolved. In this study, we used 584 nuclear loci collected using targeted sequenced capture to estimate the phylogenetic relationships among 26 species representing the two subgenera within Liolaemus (Eulaemus + Liolaemus), and all major groups within Eulaemus. Previous molecular and morphological-based phylogenetic analyses of Eulaemus based on a limited number of characters resolved few higher-level relationships, although one point of agreement is that the early divergence within Eulaemus corresponds to the lineomaculatus section, followed by the diversification of eight main clades that are strongly supported and recognized. Liolaemus probably experienced relatively rapid divergences during parts of its evolutionary history, and a phylogenomic approach was used to resolve the relationships among the major groups. The new analyses presented here support the division of Liolaemus into two subgenera, and resolve relationships among many of the major clades of Eulaemus with strong support. A Bayesian divergence dating analysis using 44 protein-coding genes provides an estimation of the split of the two Liolaemus subgenera of approximately 19,7 ma (95% HPD = 16,94 - 23,04), while diversification within Eulaemus started at 15,05 ma (95% HPD = 12,94 - 17,59) among the L. lineomaculatus and the L. https://www.selleckchem.com/ALK.html montanus series by Mid Miocene. A novel phylogenetic network analyses for SNP data identified two hybridizing edges among different groups of Eulaemus at different points in time. Having a solid phylogenetic hypothesis of the main Eulaemus clades opens new opportunities to test a variety of macroevolutionary questions for this unique radiation. BACKGROUND Pediatric Intensive Care Unit (PICU) teams provide care for critically ill children with diverse and often complex medical and surgical conditions. Researchers often lack guidance on an approach to select the best outcomes when evaluating this critically ill population. Studies would be enhanced by incorporating multi-stakeholder preferences to better evaluate clinical care. This manuscript outlines the methodology currently being used to develop a PICU Core Outcome Set (COS). This PICU COS utilizes mixed methods, an inclusive stakeholder approach, and a modified Delphi consensus process that will serve as a resource for PICU research programs. METHODS A Scoping Review of the PICU literature evaluating outcomes after pediatric critical illness, a qualitative study interviewing PICU survivors and their parents, and other relevant literature will serve to inform a modified, international Delphi consensus process. The Delphi process will derive a set of minimum domains for evaluation of outcomes of critically ill children and their families. Delphi respondents include researchers, multidisciplinary clinicians, families and former patients, research funding agencies, payors, and advocates. Consensus meetings will refine and finalize the domains of the COS, outline a battery instruments for use in future studies, and prepare for extensive dissemination for broad implementation. DISCUSSION The PICU COS will be a guideline resource for investigators to assure that outcomes most important to all stakeholders are considered in PICU clinical research in addition to those deemed most important to individual scientists. TRIAL REGISTRATION COMET database (http//www.comet-initiative.org/, Record ID 1131, 01/01/18). BACKGROUND Cancer-related fatigue is a significant problem and is associated with poor quality of life. Behavioral interventions include exercise and cognitive-behavioral therapy, which survivors may be unwilling or unable to adopt. Pharmacologic interventions (e.g., selective serotonin reuptake inhibitors) have been disappointing. One potential therapy is the antidepressant bupropion, a norepinephrine-dopamine reuptake inhibitor that targets both inflammation and the hypothalamic-pituitary-adrenal axis. The current study is intended to provide a rigorous test of the efficacy and tolerability of bupropion for cancer-related fatigue. METHODS A randomized, double-blind, placebo-controlled trial will examine the effects of bupropion on cancer-related fatigue. The trial will be conducted nationwide through the University of Rochester Medical Center (URMC) National Cancer Institute Community Oncology Research Program (NCORP). Disease-free breast cancer survivors (n = 422) who completed chemotherapy and/or radiotherapy 12-60 months previously and report significant fatigue will be randomized 11 to receive bupropion (300 mg/day) or placebo. Outcomes will be assessed at baseline and the 12-week follow-up. The primary outcome, fatigue, will be measured with the Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F). Secondary outcomes include quality of life, depression, and drug tolerability. Exploratory outcomes include cognition and symptomatology. Potential biological mechanisms and genetic moderators of cancer-related fatigue will also be explored. DISCUSSION This study is the first placebo-controlled trial to our knowledge to evaluate bupropion for cancer-related fatigue. Positive results could revolutionize the treatment of cancer-related fatigue, as bupropion is safe, inexpensive, widely-available, and may be more tolerable and acceptable for many patients than current, limited treatment options. INTRODUCTION To evaluate, factors associated with new ultrasonographic lesions of the anterior chest wall in spondyloarthritis (SpA) after a follow up of 5 years. METHODS SpA Patients included in 2013 in a first study were evaluated five years later. Ultrasound B mode and power Doppler examination of the two sternoclavicular joints and the manubrio-sternal joint were performed by the same two examinators at baseline and five years later. The presence of erosion, synovitis, ankylosis, power Doppler signal, joint effusion and joint space narrowing were assessed blind of the first evaluation. RESULTS Among the 131 patients at baseline, 58 patients were evaluated 5 years later. The mean age was 48.2 +/- 11.9 years old, with 86% of male and mainly an axial disease (78%). Patient characteristics are comparable to the original cohort. The most frequent lesions were ankylosis of the manubriosternal joint (38%) and erosions of the sternoclavicular joint (29 %). 31 patients (53%) developed a new lesion of the ACW. There is a statistically significant association between new lesions of the ACW and higher ASDAS CRP (1,86 +/- 1,07 VS 3,0 +/- 2,17 p less then 0,01) and with CRP (5,34 +/- 7,85 VS 16,2 +/- 35, p = 0,035) in the moment of the examination.
