Diabetes Conflict Outstrips The Positive Impact Of Self-Efficacy On Youth Adherence And Glycemic Control In Type 1 Diabetes., Amy E. Noser, Lindsay Huffhines, Mark A. Clements, Susana R. Patton

Manuscripts, Articles, Book Chapters and Other Papers

Objective: To examine whether self-efficacy buffers the deleterious consequences of diabetes-specific family conflict on self-monitoring blood glucose (SMBG) and glycated hemoglobin (HbA1c) in youth with type 1 diabetes mellitus (T1DM).

Methods: A total of 129 youth with T1DM (aged 10-16 years) completed measures of diabetes-specific family conflict and self-efficacy for diabetes management, and their blood glucose meter data and HbA1c were extracted from the electronic medical record. We preformed moderation analyses to examine whether self-efficacy moderated the association that diabetes-specific family conflict had with SMBG and HbA1c. We used simple slopes analyses to probe significant interactions.

Results: Our results indicated …

Pro-Inflammatory Chemokines And Cytokines Dominate The Blister Fluid Molecular Signature In Patients With Epidermolysis Bullosa And Affect Leukocyte And Stem Cell Migration., Vitali Alexeev, Julio Cesar Salas-Alanis, Francis Palisson, Lila Mukhtarzada, Giulio Fortuna, Jouni Uitto, Andrew P. South, Olga Igoucheva

Department of Dermatology and Cutaneous Biology Faculty Papers

Hereditary epidermolysis bullosa (EB) is associated with skin blistering and the development of chronic nonhealing wounds. Although clinical studies have shown that cell-based therapies improve wound healing, the recruitment of therapeutic cells to blistering skin and to more advanced skin lesions remains a challenge. Here, we analyzed cytokines and chemokines in blister fluids of patients affected by dystrophic, junctional, and simplex EB. Our analysis revealed high levels of CXCR1, CXCR2, CCR2, and CCR4 ligands, particularly dominant in dystrophic and junctional EB. In vitro migration assays demonstrated the preferential recruitment of CCR4⁺ lymphocytes and CXCR1⁺, CXCR2⁺, …

Vitamin D, Heidi D Moretti, Vincent J Colucci, Bradley D Berry

Articles, Abstracts, and Reports

BACKGROUND: Vitamin D status may influence heart failure (HF) patient outcomes by affecting b-type natriuretic peptide (BNP), parathyroid hormone (PTH), and enhancing cardiac contractility. Vitamin D deficiency is associated with morbidity and mortality in HF patients. The objective of this study was to determine if vitamin D3 at a comparatively high dose would replete 25-hydroxyvitamin D (25(OH)D) stores, improve BNP, PTH, cardiopulmonary function, reduce inflammatory markers, and improve quality of life (QOL) in HF patients.

METHODS: This was a 6 month, parallel group, double-blind, placebo-controlled, single clinic center, randomized trial of supplemental vitamin D3 using a dose of 10,000 IU …

Lower Body Stiffness Variations And Associated Injury Risk During Sports Specific Tasks, Emma Millett, Mark Moresi, Mark Watsford, Paul Taylor, David Greene

ISBS Proceedings Archive

The purpose of this study was to evaluate the longitudinal stiffness changes and associated prospective lower limb injury risk across a season of training in female athletes. Thirty-nine high level female athletes from varied training backgrounds completed sports-specific tasks and repetitive hopping. Repeated measures analysis of variance, independent t-tests, receiver operating characteristics curves and logistic regression analysis were implemented to evaluate the identified aims of this study. Results suggest athletic training influences longitudinal changes in leg stiffness which may place athletes at increased injury risk. An optimal range of stiffness may exist allowing optimal performance and minimised injury risk.

Maternal undernutrition is a major concern globally, contributing to poor birth outcomes. Limited evidence exists on delivering multiple interventions for maternal nutrition simultaneously. Alive & Thrive addressed this gap by integrating nutrition-focused interpersonal counseling, community mobilization, distribution of free micronutrient supplements, and weight-gain monitoring through an existing Maternal, Neonatal, and Child Health (MNCH) program in Bangladesh. We evaluated the effect of providing nutrition-focused MNCH compared with standard MNCH (antenatal care with standard nutrition counseling) on coverage of nutrition interventions, maternal dietary diversity, micronutrient supplement intake, and early breastfeeding practices. We used a cluster-randomized design with cross-sectional surveys at baseline (2015) …

Cruciferous And Allium Vegetable Intakes Are Inversely Associated With 15‐Year Atherosclerotic Vascular Disease Deaths In Older Adult Women, Lauren Blekkenhorst, Catherine P. Bondonno, Joshua Lewis, Amanda Devine, Kun Zhu, Wai Lim, Richard Woodman, Lawrence Beilin, Richard Prince, Jonathan M. Hodgson

Research outputs 2014 to 2021

Background

Higher vegetable intake is consistently associated with lower atherosclerotic vascular disease (ASVD) events. However, the components responsible and mechanisms involved are uncertain. Nonnutritive phytochemicals may be involved. The objective of this study was to investigate the associations of total vegetable intake and types of vegetables grouped according to phytochemical constituents with ASVD mortality.

Methods and Results

The cohort consisted of 1226 Australian women aged 70 years and older without clinical ASVD or diabetes mellitus at baseline (1998). Vegetable intakes were calculated per serving (75 g/d) and were also classified into prespecified types relating to phytochemical constituents. ASVD‐related deaths were …

The Impact Of Rare Variation On Gene Expression Across Tissues, Xin Li, Colby Chiang, Alexandra J Scott, Ira M Hall, Et Al

Open Access Publications

Rare genetic variants are abundant in humans and are expected to contribute to individual disease risk. While genetic association studies have successfully identified common genetic variants associated with susceptibility, these studies are not practical for identifying rare variants. Efforts to distinguish pathogenic variants from benign rare variants have leveraged the genetic code to identify deleterious protein-coding alleles, but no analogous code exists for non-coding variants. Therefore, ascertaining which rare variants have phenotypic effects remains a major challenge. Rare non-coding variants have been associated with extreme gene expression in studies using single tissues, but their effects across tissues are unknown. Here …

Mycobacterium tuberculosis (Mtb) is a global health threat, compounded by the emergence of drug-resistant strains. A hallmark of pulmonary tuberculosis (TB) is the formation of hypoxic necrotic granulomas, which upon disintegration, release infectious Mtb. Furthermore, hypoxic necrotic granulomas are associated with increased disease severity and provide a niche for drug-resistant Mtb. However, the host immune responses that promote the development of hypoxic TB granulomas are not well described. Using a necrotic Mtb mouse model, we show that loss of Mtb virulence factors, such as phenolic glycolipids, decreases the production of the proinflammatory cytokine IL-17 (also referred to as IL-17A). IL-17 …

Clinician–investigators, also called physician–scientists, offer critical knowledge and perspectives that benefit research on basic science mechanisms, improved diagnostic and therapeutic approaches, population and outcomes medicine, health policy, and health services, yet few clinically trained health professionals pursue a research career. Sustaining this workforce requires attention to the unique challenges faced by investigators who must achieve clinical and research competence during training and their careers. These challenges include the duration of required clinical training, limited or discontinuous research opportunities, high levels of educational debt, balancing the dual obligations and rewards of clinical care and research, competition for research funding, and the …

Vocabulary Learning Benefits From Rem After Slow-Wave Sleep., Laura J Batterink, Carmen E Westerberg, Ken A Paller

Brain and Mind Institute Researchers' Publications

Memory reactivation during slow-wave sleep (SWS) influences the consolidation of recently acquired knowledge. This reactivation occurs spontaneously during sleep but can also be triggered by presenting learning-related cues, a technique known as targeted memory reactivation (TMR). Here we examined whether TMR can improve vocabulary learning. Participants learned the meanings of 60 novel words. Auditory cues for half the words were subsequently presented during SWS in an afternoon nap. Memory performance for cued versus uncued words did not differ at the group level but was systematically influenced by REM sleep duration. Participants who obtained relatively greater amounts of REM showed a …

Circulating Early- And Mid-Pregnancy Micrornas And Risk Of Gestational Diabetes., Pandora L Wander, Edward J Boyko, Karin Hevner, Viraj J Parikh, Mahlet G Tadesse, Tanya K Sorensen, Michelle A Williams, Daniel A Enquobahrie

Articles, Abstracts, and Reports

AIMS: Epigenetic regulators, including microRNAs (miRNAs), are implicated in type 2 diabetes, but evidence linking circulating miRNAs in pregnancy and risk of gestational diabetes (GDM) is sparse. Potential modifiers, including pre-pregnancy overweight/obesity and offspring sex, are unexamined. We hypothesized that circulating levels of early-mid-pregnancy (range 7-23weeks of gestation) candidate miRNAs are related to subsequent development of GDM. We also hypothesized that miRNA-GDM associations might vary by pre-pregnancy body-mass index (ppBMI) or offspring sex.

METHODS: In a case-control analysis (36GDM cases/80 controls) from the Omega study, a prospective cohort study of pregnancy complications, we measured early-mid-pregnancy plasma levels of 10miRNAs chosen …

Neuroscience Faculty Publications

Aging is associated with declines in executive function. We examined how executive functional brain systems are influenced by clinically silent Alzheimer’s disease (AD) pathology and cerebral white matter hyperintensities (WMHs). Twenty-nine younger adults and thirty-four cognitively normal older adults completed a working memory paradigm while functional magnetic resonance imaging (fMRI) was performed. Older adults further underwent lumbar cerebrospinal fluid (CSF) draw for assessment of AD pathology and FLAIR imaging for assessment of WMHs. Accurate working memory performance in both age groups was associated with high fronto-visual functional connectivity (fC). However, in older adults, higher expression of fronto-visual fC was linked …
