Following the Growth of Sarah\u27s baby: An IPE Activity for Medical Nutrition & Diagnostic Sonography Students

Objectives: Interprofessional education (IPE) involves collaborative learning among students from different professions. While acceptance of these types of activities is increasing, there are opportunities to expand the number of health care professions involved in IPE. The purpose of this study was to explore student perceptions and outcomes after participation in a Diagnostic Medical Sonography (DMS) and Medical Nutrition Education (MNE) interprofessional education activity centered around a clinical case study on fetal growth. Subjects & Methods: The IPE activity was administered to four student cohorts from academic years to 2015-2016 to 2018-2019. Participants included 66 students (n=39 DMS and n=27 MNE). Data was gathered through pre- & post-tests based on a patient case-study and evidence-based search skills knowledge and a post-activity survey. Assessment sessions were held on the first day and on the last day of the activity. Results: There was a statistically significant difference in the mean pre-and post-test scores for the group overall, (p=https://digitalcommons.unmc.edu/cahp_mits_pres/1004/thumbnail.jp

Broad Repertoire of T Cell Autoreactivity Directly from Islets of Donors with Type 1 Diabetes (T1D)

Type 1 diabetes (T1D) is an autoimmune disease characterized by the infiltration of lymphocytes into the insulin-producing β-cells in the pancreas. We have isolated live T cells sorted or grown directly from the isolated, handpicked islets of human donors with T1D. We received ~500 islet equivalent EQ of variable purity (10-90%) from 12 donors with T1D (disease duration 0.42-20 years) and from seven control donors and two donors with type 2 diabetes (T2D). A total of 321 T cell lines and clones were derived from the islets of donors with T1D (3 lines from the 9 control donors). These are 131 CD4+ lines and clones, 47 CD8+ lines and 143 lines that contain both CD4+ and CD8+ T cells. From 50 lines and clones examined to date, we have determined the autoreactivity of 19 and have seen a broad repertoire of T cell autoreactivity in the islets, including characterized targets and post-translationally modified targets. Autoreactivity of CD4+ T cell lines was to three different peptides from glutamic acid decarboxylase 65 (GAD; GAD115-127, GAD274-286, GAD555-567), proinsulin76-90, and to chromogranin A or proinsulin expressed by DR4+DQ8+ B cells transduced with lentivirus containing constructs with the open reading frames corresponding to whole autoantigens. Reactivity to modified peptides included the glucose-regulated protein 78 and islet amyloid polypeptide with arginine to citrulline modifications (GRP78292-305(Arg-Cit297) and IAPP65-84(Arg-Cit 73, 81)), deaminations (IA-2545-562(Gln-Glu 548, 551, 556), and to several insulin hybrid peptides. These autoreactive CD4+ T cell lines and clones secreted only pro-inflammatory cytokines (IFN-γ, TNFα) upon peptide stimulation. For CD8+ T cells from islets, from one donor with T1D, we saw binding of a pool of HLA-A2 pentamers loaded with insulin B10-18, IA-2797-805 and insulin specific glucose-6-phosphatase catalytic subunit related protein, IGRP265-273. These results have implications for the development of successful prevention and reversal therapeutic strategies in T1D

ProsCan for Couples: Randomised controlled trial of a couples-based sexuality intervention for men with localised prostate cancer who receive radical prostatectomy

Background: Prostate cancer is the most common male cancer in the Western world. The most substantial long term morbidity from this cancer is sexual dysfunction with consequent adverse changes in couple and intimate relationships. Research to date has not identified an effective way to improve sexual and psychosocial adjustment for both men with prostate cancer and their partners. As well, the efficacy and cost effectiveness of peer counselling as opposed to professional models of service delivery has not yet been empirically tested. This paper presents the design of a three arm randomised controlled trial (peer vs. nurse counselling vs. usual care) that will evaluate the efficacy of two couples-based sexuality interventions (ProsCan for Couples: Peer support vs. nurse counselling) on men's and women's sexual and psychosocial adjustment after surgical treatment for localised prostate cancer; in addition to cost-effectiveness. Methods/design: Seventy couples per condition (210 couples in total) will be recruited after diagnosis and before treatment through urology private practices and hospital outpatient clinics and randomised to (1) usual care; (2) eight sessions of peer-delivered telephone support with DVD education; and (3) eight sessions of oncology nurse-delivered telephone counselling with DVD education. Two intervention sessions will be delivered before surgery and six over the six months post-surgery. The intervention will utilise a cognitive behavioural approach along with couple relationship education focussed on relationship enhancement and helping the couple to conjointly manage the stresses of cancer diagnosis and treatment. Participants will be assessed at baseline (before surgery) and 3, 6 and 12 months post-surgery. Outcome measures include: Sexual adjustment; unmet sexuality supportive care needs; attitudes to sexual help seeking; psychological adjustment; benefit finding and quality of life. Discussion: The study will provide recommendations about the efficacy of peer support vs. nurse counselling to facilitate better sexual and couple adjustment after prostate cancer as well as recommendations on whether the interventions represent efficient health service delivery

Luxury brands consumption: The segment of “Chandlers”

The purpose of this paper is to introduce the segment of “chandlers” to the Russian academic society and to describe the specifics of their contemporary consumer behavior. The term “chandler” for this study was borrowed from American classical literature and applied to marketing. The study was conducted in April 2016 and comprised of two stages. The first stage was a series of in-depth interviews with seven representatives of the target audience from Moscow. It allowed to formulate the hypotheses which were proved/disproved by these hypotheses during the online survey. 117 relevant respondents were chosen for the study (72 — from Moscow, 45 — from regional city Ufa). The results allowed to formulate a preliminary conclusion there are no сhandlers in Ufa now. The most popular luxury brands for the Moscow сhandlers and specifics of their consumption were determined. This research is the first descriptive step to understanding the specifics of contemporary сhandlers — how they manage to consume luxury in the form of material artefacts and services, while being kept on a shoestring budget. The research entails a few limitations. The investigation comprised only a limited numbers of the respondents from Russian cities as Moscow and Ufa. In future, more consumers will be involved in the sample to cover more cities in Russia and respondents from other countries will be included. Upon the research completion a range of the recommendations has been provided to the luxury producers whose brands are already presented in Moscow and also for those who are planning to open their stores there. The results may serve as a guide for marketing tools development in the luxury industry. The originality of the paper lies in the term “chandlers’ segment” which is introduced in marketing theory for the first time

A recurrent germline PAX5 mutation confers susceptibility to pre-B cell acute lymphoblastic leukemia

Somatic alterations of the lymphoid transcription factor gene PAX5 (also known as BSAP) are a hallmark of B cell precursor acute lymphoblastic leukemia (B-ALL)1–3, but inherited mutations of PAX5 have not previously been described. Here we report a new heterozygous germline variant, c.547G>A (p.Gly183Ser), affecting the octapeptide domain of PAX5 that was found to segregate with disease in two unrelated kindreds with autosomal dominant B-ALL. Leukemic cells from all affected individuals in both families exhibited 9p deletion, with loss of heterozygosity and retention of the mutant PAX5 allele at 9p13. Two additional sporadic ALL cases with 9p loss harbored somatic PAX5 substitutions affecting Gly183. Functional and gene expression analysis of the PAX5 mutation demonstrated that it had significantly reduced transcriptional activity. These data extend the role of PAX5 alterations in the pathogenesis of pre-B cell ALL and implicate PAX5 in a new syndrome of susceptibility to pre-B cell neoplasia

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

HMJ Underhill Archive

This project began in September 2001 with the re-discovery of an old archive in the Institute of Archaeology (Oxford University). The archive consists of a collection of hand-painted glass (lantern) slides that depicted the "Megalithic Monuments of Great Britain," dating to 1897-5 and attributed to H.M.J. Underhill. The slides showed the stone circles at Stonehenge, Avebury, Stanton Drew and the Rollright Stones. Miscellaneous slides depicted other prehistoric monuments: Menhir at Dartmoor and the Sarsen Stones and Wayland's Smithy on the Oxfordshire Ridgeway. Since September 2001, more lantern slides in the Institute's collections have been attributed to Underhill on different subjects: Romano-British city remains (Bath, Colchester, Silchester and Wroxeter) and the vernacular architecture of windmills. The researchers, Megan Price and Deborah Harlan, used primary sources in the Bodleian Library Modern Manuscripts Collection and the Centre for Oxfordshire Studies to uncover much biographical information on Henry Michael John Underhill. We have also located further archives in the United Kingdom that hold Underhill material. The Underhill archive consists of 78 hand-painted glass slides and 17 photographic glass lantern slides. Each slide measures 3.25 inches square

Tracking donor-reactive T cells: Evidence for clonal deletion in tolerant kidney transplant patients

T cell responses to allogeneic major histocompatibility complex antigens present a formidable barrier to organ transplantation, necessitating long-term immunosuppression to minimize rejection. Chronic rejection and drug-induced morbidities are major limitations that could be overcome by allograft tolerance induction. Tolerance was first intentionally induced in humans via combined kidney and bone marrow transplantation (CKBMT), but the mechanisms of tolerance in these patients are incompletely understood. We now establish an assay to identify donor-reactive T cells and test the role of deletion in tolerance after CKBMT. Using high-throughput sequencing of the T cell receptor B chain CDR3 region, we define a fingerprint of the donor-reactive T cell repertoire before transplantation and track those clones after transplant. We observed posttransplant reductions in donor-reactive T cell clones in three tolerant CKBMT patients; such reductions were not observed in a fourth, nontolerant, CKBMT patient or in two conventional kidney transplant recipients on standard immunosuppressive regimens. T cell repertoire turnover due to lymphocyte-depleting conditioning only partially accounted for the observed reductions in tolerant patients; in fact, conventional transplant recipients showed expansion of circulating donor-reactive clones, despite extensive repertoire turnover. Moreover, loss of donor-reactive T cell clones more closely associated with tolerance induction than in vitro functional assays. Our analysis supports clonal deletion as a mechanism of allograft tolerance in CKBMT patients. The results validate the contribution of donor-reactive T cell clones identified before transplant by our method, supporting further exploration as a potential biomarker of transplant outcomes.status: publishe
