BACKGROUND AND AIMS: Immunosuppressive therapy for inflammatory bowel disease (IBD) in pediatric patients is thought to increase risk of malignancy and lymphoproliferative disorders, including hemophagocytic lymphohistiocytosis (HLH). We compared unadjusted incidence rates and of malignancy and HLH in pediatric patients with IBD exposed to infliximab compared with patients not exposed to biologics and calculated standardized incidence ratios (SIRs). METHODS: We collected and analyzed data from 5766 participants in a prospective study of long-term outcomes of pediatric patients with IBD (NCT00606346), from 2007 through 30 June 2016...

OBJECTIVES: To compare the effect of traction during non-arthrographic and arthrographic MR examination of the wrist with regard to joint space width, joint fluid dispersion, and cartilage surface visibility. METHODS: Prospective 3T MRI study of 100 wrists in 96 patients. The first 50 wrists underwent MR arthrography first without traction and then with traction. The following 50 wrists underwent standard MR first without traction and then with traction. On these examinations, two radiologists independently measured (i) joint space width, and semi-quantitatively graded (ii) joint fluid dispersion between opposing cartilage surfaces, as well as (iii) articular cartilage surface visibility...

Temporal manipulation of the in vitro environment and growth factors can direct differentiation of human pluripotent stem cells into organoids, aggregates with multiple tissue-specific cell types and three-dimensional structure mimicking native organs. A mechanistic understanding of early organoid formation is essential for improving the robustness of these methods, which is necessary prior to use in drug development and regenerative medicine. We investigated intestinal organoid emergence, focusing on measurable parameters of hindgut spheroids, the intermediate step between definitive endoderm and mature organoids...

Vitamin D deficiency is common in patients with chronic obstructive pulmonary disease (COPD), yet a comprehensive analysis of environmental and genetic determinants of serum 25-hydroxyvitamin D (25[OH]D) concentration in patients with this condition is lacking. We conducted a multi-centre cross-sectional study in 278 COPD patients aged 41-92 years in London, UK. Details of potential environmental determinants of vitamin D status and COPD symptom control and severity were collected by questionnaire, and blood samples were taken for analysis of serum 25(OH)D concentration and DNA extraction...

Bronchiectasis Nontuberculous mycobacterium (NTMnb) infection is an emerging health problem in breast cancer (BCa) patients. We measured sera exosome proteome in BCa-NTMnb subjects and controls by Mass Spectroscopy. Extracellular matrix protein 1 (ECM1) was detected exclusively in the circulating exosomes of 82% of the BCa-NTMnb cases. Co-culture of ECM1+ exosomes with normal human mammary epithelial cells induced epithelial to mesenchymal transition accompanied by increased Vimentin/CDH1 expression ratio and Glutamate production...

BACKGROUND & AIMS: There is controversy over the role of the type 2 immune response in pathogenesis of ulcerative colitis (UC)-few data are available from treatment-naïve patients. We investigated whether genes associated with a type 2 immune response in the intestinal mucosa are upregulated in treatment-naïve pediatric patients with UC, compared to patients with Crohn's disease (CD)-associated colitis or without inflammatory bowel disease (IBD), and whether expression levels associate with clinical outcomes...

BACKGROUND: Treg dysfunction or deficiency results in unopposed immune activation and autoimmunity. Interleukin-2 (IL-2) is critical for the expansion, suppressive function, and maintenance of Tregs. Although conventional T cells and NK cells respond to IL-2, Tregs are more sensitive to lower concentrations of IL-2 due to constitutive expression of CD25, the high affinity IL-2 receptor. Low-dose IL-2 therapies have shown to preferentially expand Tregs and ameliorate manifestations of graft versus host disease (Koreth et al...

BACKGROUND: Long non-coding RNAs (lncRNA) regulate gene transcription and diverse cellular functions. We have recently reported a core inflammatory and metabolic ileal gene signature in treatment naïve pediatric Crohn Disease (CD), but the potential role of lncRNA was not known. We hypothesized that differences in ileal lncRNA would be associated with differences in protein-coding gene expression, suggesting a role for lncRNA in regulating those gene signatures. METHODS: Poly-A selected RNA-seq and Ensembl annotation were used to define differentially expressed ileal genes with false discovery rate correction of 0...

There is increasing interest by consumers, researchers, and regulators into the roles that certain bioactive compounds, derived from plants and other natural sources, can play in health maintenance and promotion, and even prolonging a productive quality of life. Research has rapidly emerged suggesting that a wide range of compounds and mixtures in and from plants (such as fruits and vegetables, tea and cocoa) and animals (such as fish and probiotics) may exert substantial health benefits. There is interest in exploring the possibility of establishing recommended intakes or dietary guidance for certain bioactive substances to help educate consumers...

BACKGROUND: UK government policy aims to strengthen the role of community pharmacies in health promotion. Thus, we conducted feasibility studies for an intervention to enhance delivery of the NHS Smoking Cessation Service. METHODS: The overall aims were to assess acceptability and feasibility of conducting the intervention in community pharmacies and piloting this with a cluster randomised trial. Specific objectives were (1) to estimate likely participation rates of pharmacies and stop smoking advisors, (2) to establish the potential impact of the training intervention on throughput and retention of smokers in smoking services, (3) to establish potential impact on smoking cessation outcomes, (4) to optimise logistics for conducting a cluster randomised trial in the next phase of the research programme and (5) to consider the feasibility of collecting pharmacy and service user data...

BACKGROUND: Considerable variability exists in normal developmental lumbar spinal canal size. This impacts the likelihood of neural compromise. Spinal canal development is complete by 17 years. As diseases incurred thereafter do not knowingly affect the developmental size of the spinal canal, it is reasonable to use a selected population undergoing abdominopelvic computed tomography (CT) examination to determine developmental lumbar spinal canal size. METHODS: Study approval was granted by the Clinical Research Ethics Committee...

Using an automated cell counting technique developed previously (Case et al., Ecology and Evolution 2014; 4: 3494), we explore the lifespan effects of lac-1, a ceramide synthase gene paralogous to lag-1 in Neurospora crassa in conjunction with the band bd (ras-1) gene. We find that the replicative lifespan of a lac-1(KO)bd double mutants is short, about one race tube cycle, and this double mutant lacks a strong ~21-hr clock cycle as shown by race tube and fluorometer analysis of fluorescent strains including lac-1(KO) ...

Assessment of genetic diversity and connectivity between regions can inform conservation managers about risk of inbreeding, potential for adaptation and where population boundaries lie. The Gouldian finch (Erythrura gouldiae) is a threatened species in northern Australia, occupying the savannah woodlands of the biogeographically complex monsoon tropics. We present the most comprehensive population genetic analysis of diversity and structure the Gouldian finch using 16 microsatellite markers, mitochondrial control region and 3,389 SNPs from genotyping-by-sequencing...
