The use of biological agents for the treatment of chronic inflammatory conditions such as inflammatory bowel diseases (IBD) has been on the rise.1,2 Current biological therapies include antitumor necrosis factor-α (anti-TNF-α), anti-interleukin-12/23, and anti-integrin agents. Before initiation of biological drugs, screening for Mycobacterium tuberculosis infection is required to avoid reactivation or worsening of disease after immunosuppression. It has been shown that anti-TNF-α treated patients have a 14-fold increased risk of tuberculosis (TB) infection/reactivation compared with healthy controls.3 The methods for screening for TB have evolved over time and vary from region to region.Objective This study examined (a) the nature and prevalence of pain in youth with spina bifida (SB) (b) common coping responses to pain, and (c) longitudinal, bi-directional associations between internalizing symptoms and pain characteristics. Methods Data were collected from youth (N = 140, 53.6% female, ages 8-15 at Time 1) and their parents and teachers at two time points spaced 2 years apart. Youth reported on several pain characteristics and coping responses. Multiple informants reported on child internalizing symptoms. Evaluation of Aims 1-3 was based on descriptive analyses, bivariate correlations, and linear and logistic regressions. Results About 25% of the sample reported chronic pain (e.g., experiencing pain one or more times per week over the past 3 months) at Time 1 or 2, with roughly one-third of this chronic pain subsample reporting chronic pain both time points. Pain was usually rated as mild in intensity for the full sample and most commonly experienced in the head, abdomen, and back, and described as "aching." Youth with chronic pain reported significantly higher pain intensity and tended to use condition-specific methods to cope with pain (e.g., taking off braces). In 2 of 10 analyses, internalizing symptoms at Time 1 were associated with chronic pain and pain intensity at Time 2. Conclusions Roughly one-fourth of youth with SB are at risk for experiencing chronic pain, highlighting the need for increased assessment and treatment of pain in this population. Youth psychological functioning appears to more often precede, rather than being a consequence of pain symptoms.Context Military personnel are subjected to physiologically stressful environments during combat and its associated training. Evidence suggests that fish oil-derived n-3 polyunsaturated fatty acids (FO n-3 PUFAs) may affect military personnel's performance by promoting or preserving lean body mass, strength, and power, while enhancing recovery from training-associated muscle damage. Objective Following PRISMA guidelines, this systematic review assessed the evidence for FO n-3 PUFA supplementation across various military-relevant outcomes related to physical performance in healthy adult populations. Data sources The PubMed, Embase, and the CINAHL databases were searched along with references lists of selected articles and reviews. Data extraction Eighteen trials were assessed for bias, and descriptive data were extracted. Data analysis Of the 18 studies included, 12 trials favored FO n-3 PUFA supplementation in ≥ 1 of the performance outcomes. Conclusion Overall, FO n-3 PUFA supplementation likely preserves strength and very likely enhances recovery from physiological stress in young, healthy adults. However, FO n-3 PUFAs' role in promoting or preserving lean body mass or promoting strength is unclear and warrants additional investigation. Systematic review registration PROSPERO registration no.

The Belgian Society of Gerontology and Geriatrics has developed evidence-based guidelines for the prevention and treatment of sarcopenia. This umbrella review presents the results of the Working Group on Nutritional Interventions. Objective The aim of this umbrella review was to provide an evidence-based overview of nutritional interventions targeting sarcopenia or at least 1 of the 3 sarcopenia criteria (ie, muscle mass, muscle strength, or physical performance) in persons aged ≥ 65 years. Data sources Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the PubMed and Web of Science databases were searched for systematic reviews and meta-analyses reporting the effect of nutritional supplementation on sarcopenia or muscle mass, strength, or physical performance. Data extraction Two authors extracted datenia. Protein supplementation on top of resistance training is recommended to increase muscle mass and strength, in particular for obese persons and for ≥ 24 weeks. Effects on sarcopenia as a construct were not reported in the included reviews.Yap1 and its paralogue Taz largely control epithelial tissue growth. We have identified that hematopoietic stem cell (HSC) fitness response to stress depends on Yap1 and Taz. Deletion of Yap1 and Taz induces a loss of HSC quiescence, symmetric self-renewal ability and renders HSC more vulnerable to serial myeloablative 5-fluorouracil treatment. This effect depends on the predominant cytosolic polarization of Yap1 through its PDZ domain-mediated interaction with the scaffold Scribble. Scribble and Yap1 coordinate to control cytoplasmic Cdc42 activity and HSC fate determination in vivo. Deletion of Scribble disrupts Yap1 co-polarization with Cdc42 and decreases Cdc42 activity, resulting in increased self-renewing HSC with competitive reconstitution advantages. These data suggest that Scribble/Yap1 co-polarization is indispensable for Cdc42-dependent activity on HSC asymmetric division and fate. The combined loss of Scribble, Yap1 and Taz results in transcriptional upregulation of Rac-specific guanine nucleotide exchange factors, Rac activation and HSC fitness restoration. Scribble links Cdc42 and the cytosolic functions of the Hippo signaling cascade in HSC fate determination.Hematopoietic-cell transplantation (HCT) from HLA-mismatched unrelated donors can cure life-threatening blood disorders but its success is limited by graft-versus-host disease (GVHD). HLA-B leaders encode methionine (M) or threonine (T) at position 2 and give rise to TT, MT or MM genotypes. The dimorphic HLA-B leader informs GVHD risk in HLA-B-mismatched HCT. If the leader influences outcome in other HLA-mismatched transplant settings, the success of HCT could be improved for future patients. OPB-171775 cost We determined leader genotypes for 11872 patients transplanted between 1988 and 2016 from unrelated donors with one HLA-A -B,-C,-DRB1 or -DQB1 mismatch. Multivariate regression methods were used to evaluate risks associated with patient leader genotype according to the mismatched HLA locus and with HLA-A,-B,-C,-DRB1 or -DQB1 mismatching according to patient leader genotype. The impact of the patient leader genotype on acute GVHD and mortality varied across different mismatched HLA loci. Non-relapse mortality was higher among HLA-DQB1-mismatched MM patients compared to HLA-DQB1-mismatched TT patients (hazard ratio 1.
