Improving Communication In Intensive Care Unit To Ward Transitions: Protocol For Multisite National Implementation Of The Icu-Pause Handoff Tool, Elle Mizuki Fukui, Patrick G Lyons, Emily Harris, Emma K Mccune, Juan C Rojas, Lekshmi Santhosh

2020-Current year OA Pubs

BACKGROUND: The intensive care unit (ICU)-ward transfer poses a particularly high-risk period for patients. The period after transfer has been associated with adverse events and additional work for care teams related to miscommunication or omission of information. Standardized handoff processes have been found to reduce communication errors and adverse patient events in other clinical environments but are understudied at the ICU-ward interface. We previously developed an electronic ICU-ward transfer tool, ICU-PAUSE, which embeds the key elements and diagnostic reasoning to facilitate a safe transfer of care at ICU discharge.

OBJECTIVE: The aim of this study is to evaluate the implementation …

The Tetraspanin Transmembrane Protein Cd53 Mediates Dyslipidemia And Integrates Inflammatory And Metabolic Signaling In Hepatocytes, Cassandra B Higgins, Joshua A Adams, Matthew H Ward, Zev J Greenberg, Małgorzata Milewska, Jiameng Sun, Yiming Zhang, Luana Chiquetto Paracatu, Qian Dong, Samuel Ballentine, Weikai Li, Ilona Wandzik, Laura G Schuettpelz, Brian J Debosch

2020-Current year OA Pubs

Tetraspanins are transmembrane signaling and proinflammatory proteins. Prior work demonstrates that the tetraspanin, CD53/TSPAN25/MOX44, mediates B-cell development and lymphocyte migration to lymph nodes and is implicated in various inflammatory diseases. However, CD53 is also expressed in highly metabolic tissues, including adipose and liver; yet its function outside the lymphoid compartment is not defined. Here, we show that CD53 demarcates the nutritional and inflammatory status of hepatocytes. High-fat exposure and inflammatory stimuli induced CD53 in vivo in liver and isolated primary hepatocytes. In contrast, restricting hepatocyte glucose flux through hepatocyte glucose transporter 8 deletion or through trehalose treatment blocked CD53 induction …

The Hepatic Mitochondrial Pyruvate Carrier As A Regulator Of Systemic Metabolism And A Therapeutic Target For Treating Metabolic Disease, Kyle S Mccommis, Brian N Finck

2020-Current year OA Pubs

Pyruvate sits at an important metabolic crossroads of intermediary metabolism. As a product of glycolysis in the cytosol, it must be transported into the mitochondrial matrix for the energy stored in this nutrient to be fully harnessed to generate ATP or to become the building block of new biomolecules. Given the requirement for mitochondrial import, it is not surprising that the mitochondrial pyruvate carrier (MPC) has emerged as a target for therapeutic intervention in a variety of diseases characterized by altered mitochondrial and intermediary metabolism. In this review, we focus on the role of the MPC and related metabolic pathways …

Development Of De Novo Nonalcoholic Fatty Liver Disease Following Pancreatectomy, Vanisha Patel, Parth Shah, Daniel R. Ludwig, Chet W. Hammill, Motaz Ashkar

2020-Current year OA Pubs

De novo non-alcoholic fatty liver disease (NAFLD) after pancreatectomy is a recognized phenomenon; however, its pathophysiology is poorly understood. This study aimed to determine the incidence and identify peri-operative risk factors for the development of de novo NAFLD within various pancreatectomy groups. This single-center retrospective cohort study included patients who underwent pancreatectomy between 2000 and 2020. The incidence rate of de novo NAFLD and time to diagnosis were recorded across patients with malignant versus benign indications for pancreatectomy. The overall incidence of de novo NAFLD after pancreatectomy was 17.5% (24/136). Twenty-one percent (20/94) of patients with malignant indications for surgery …

Docosahexaenoic Acid Stability In Ready-To-Use Therapeutic Food, Genevieve James, Kevin Stephenson, Meghan Callaghan-Gillespie, Mohamed Tabita Kamara, Hui Gyu Park, J Thomas Brenna, Mark J Manary

2020-Current year OA Pubs

Ready-to-use therapeutic food (RUTF) is used to treat young children diagnosed with severe acute malnutrition. RUTF with low and balanced linoleic and alpha-linolenic acid, plus omega-3 docosahexaenoic acid (DHA), supports long-term cognitive recovery. DHA is prone to degradation due to peroxidation, possibly exacerbated by the iron inherently in RUTF. Our goals were to prepare benchtop and manufacturing scale of RUTF formulations that include DHA and measure its retention. Twenty-seven RUTF formulas with base ingredients, including oats, high oleic or commodity peanuts, and encapsulated or oil-based DHA at various levels were prepared at benchtop scale, followed by seven months of climate-controlled …

Applying Hybrid Effectiveness-Implementation Studies In Equity-Centered Policy Implementation Science, Yuka Asada, Aimee Kroll-Desrosiers, Jamie F Chriqui, Geoffrey M Curran, Karen M Emmons, Debra Haire-Joshu, Ross C Brownson

2020-Current year OA Pubs

Policy implementation science (IS) is complex, dynamic, and fraught with unique study challenges that set it apart from biomedical or clinical research. One important consideration is the ways in which policy interacts with local contexts, such as power and social disadvantage (e.g., based on ability, race, class, sexual identity, geography). The complex nature of policy IS and the need for more intentional integration of equity principles into study approaches calls for creative adaptations to existing implementation science knowledge and guidance. Effectiveness-implementation hybrid studies were developed to enhance translation of clinical research by addressing research questions around the effectiveness of an …

Elevated Liver Glycogenolysis Mediates Higher Blood Glucose During Acute Exercise In Barth Syndrome, George G. Schweitzer, Grace L. Ditzenberger, Curtis C. Hughey, Brian N. Finck, Michael R. Martino, Christina A. Pacak, Barry J. Byrne, William Todd Cade

2020-Current year OA Pubs

UNLABELLED: Barth syndrome (BTHS) is an X-linked recessive genetic disorder due to mutations in the Tafazzin (TAFAZZIN) gene that lead to cardiac and skeletal muscle mitochondrial dysfunction. Previous studies in humans with BTHS demonstrate that the defects in muscle mitochondrial oxidative metabolism result in an enhanced reliance on anaerobic metabolism during exercise to meet energy demands of muscular work. During exercise, the liver normally increases glucose production via glycogenolysis and gluconeogenesis to match the elevated rate of muscle glucose uptake and meet the ATP requirements of working muscle. However, the impact of Tafazzin deficiency on hepatic glucose production and the …

Symmetric Data-Driven Fusion Of Diffusion Tensor Mri: Age Differences In White Matter, Andrea Mendez Colmenares, Michelle B Hefner, Vince D Calhoun, Elizabeth A Salerno, Jason Fanning, Neha P Gothe, Edward Mcauley, Arthur F Kramer, Agnieszka Z Burzynska

2020-Current year OA Pubs

In the past 20 years, white matter (WM) microstructure has been studied predominantly using diffusion tensor imaging (DTI). Decreases in fractional anisotropy (FA) and increases in mean (MD) and radial diffusivity (RD) have been consistently reported in healthy aging and neurodegenerative diseases. To date, DTI parameters have been studied individually (e.g., only FA) and separately (i.e., without using the joint information across them). This approach gives limited insights into WM pathology, increases the number of multiple comparisons, and yields inconsistent correlations with cognition. To take full advantage of the information in a DTI dataset, we present the first application of …

2020-Current year OA Pubs

INTRODUCTION: Anorexia nervosa (AN) is a harmful, life-threatening illness. Patients with severe AN often receive acute treatment but, upon discharge, experience high relapse rates. Evidence-based, outpatient treatment following acute care is critical to preventing relapse; however, numerous barriers (e.g., location, financial limitations, low availability of providers) preclude individuals from accessing treatment. mHealth technologies may help to address these barriers, but research on such digital approaches for those with AN is limited. Further, such technologies should be developed with all relevant stakeholder input considered from the outset. As such, the present study aimed to garner feedback from eating disorder (ED) treatment …

Regulation Of The Volume-Regulated Anion Channel Pore-Forming Subunit Lrrc8a In The Intrahippocampal Kainic Acid Model Of Mesial Temporal Lobe Epilepsy, Manolia R. Ghouli, Carrie R. Jonak, Rajan Sah, Todd A. Fiacco, Devin K. Binder

2020-Current year OA Pubs

Volume-regulated anion channels (VRACs) are a group of ubiquitously expressed outwardly-rectifying anion channels that sense increases in cell volume and act to return cells to baseline volume through an efflux of anions and organic osmolytes, including glutamate. Because cell swelling, increased extracellular glutamate levels, and reduction of the brain extracellular space (ECS) all occur during seizure generation, we set out to determine whether VRACs are dysregulated throughout mesial temporal lobe epilepsy (MTLE), the most common form of adult epilepsy. To accomplish this, we employed the IHKA experimental model of MTLE, and probed for the expression of LRRC8A, the essential pore-forming …

Vancomycin-Induced Gut Microbial Dysbiosis Alters Enteric Neuron-Macrophage Interactions During A Critical Period Of Postnatal Development, Ellen Merrick Schill, Elisabeth L Joyce, Alexandria N Floyd, Sreeram Udayan, Brigida Rusconi, Shreya Gaddipati, Bibiana E Barrios, Vini John, Mitchell E Kaye, Devesha H Kulkarni, Jocelyn T Pauta, Keely G Mcdonald, Rodney D Newberry

Vancomycin is a broad-spectrum antibiotic widely used in cases of suspected sepsis in premature neonates. While appropriate and potentially lifesaving in this setting, early-life antibiotic exposure alters the developing microbiome and is associated with an increased risk of deadly complications, including late-onset sepsis (LOS) and necrotizing enterocolitis (NEC). Recent studies show that neonatal vancomycin treatment disrupts postnatal enteric nervous system (ENS) development in mouse pups, which is in part dependent upon neuroimmune interactions. This suggests that early-life antibiotic exposure could disrupt these interactions in the neonatal gut. Notably, a subset of tissue-resident intestinal macrophages, muscularis macrophages, has been identified as …

Supplementary Feeding And Infection Control In Pregnant Adolescents-A Secondary Analysis Of A Randomized Trial Among Malnourished Women In Sierra Leone, Aminata S Koroma, Mariama Ellie, Kadiatu Bangura, Per O Iversen, David T Hendrixson, Kevin Stephenson, Mark J Manary

2020-Current year OA Pubs

Undernutrition during pregnancy in adolescence confers a high risk of maternal morbidity and adverse birth outcomes, particularly in low-resource settings. In a secondary analysis, we hypothesized that younger undernourished pregnant adolescents (<18 years) would benefit more than undernourished pregnant adults (>20 years) from the intervention of supplementary food and anti-infective treatments. The original trial in Sierra Leone enrolled 236 younger adolescents (<18 years), 454 older adolescents (aged 18-19 years), and 741 adults (≥20 years), all with a mid-upper arm circumference ≤23 cm. Younger adolescents had lower final fundal height as well as smaller newborns (-0.3 kg; 95% confidence interval [CI], -0.3, -0.2; p < 0.001) and shorter newborns (-1.1 cm; 95% CI, -1.5, -0.7; p < 0.001) than adults. The intervention's effect varied significantly between maternal age groups: adults benefited more than younger adolescents with respect to newborn birth weight (difference in difference, 166 g; 95% CI, 26, 306; interaction p = 0.02), birth length (difference in difference, 7.4 mm; 95% CI, 0.1, 14.8; interaction p = 0.047), and risk for low birth weight (<2.5 kg) (interaction p = 0.019). The differences in response persisted despite adjustments for maternal anthropometry, the number of prior pregnancies, and human immunodeficiency virus status. Older adolescents similarly benefited more than younger adolescents, though differences did not reach statistical significance. In conclusion, newborns born to younger adolescent mothers had worse outcomes than those born to adult mothers, and adults and their newborns benefited more from the intervention than younger adolescents.

Genetics Of Vegetarianism: A Genome-Wide Association Study, Nabeel R. Yaseen, Catriona L. K. Barnes, Lingwei Sun, Akiko Takeda, John P. Rice

2020-Current year OA Pubs

A substantial body of evidence points to the heritability of dietary preferences. While vegetarianism has been practiced for millennia in various societies, its practitioners remain a small minority of people worldwide, and the role of genetics in choosing a vegetarian diet is not well understood. Dietary choices involve an interplay between the physiologic effects of dietary items, their metabolism, and taste perception, all of which are strongly influenced by genetics. In this study, we used a genome-wide association study (GWAS) to identify loci associated with strict vegetarianism in UK Biobank participants. Comparing 5,324 strict vegetarians to 329,455 controls, we identified …

Clinical Characteristics And Outcomes Of Infection With Human T-Lymphotropic Virus In A Non-Endemic Area: A Single Institution Study, Margery Gang, Feng Gao, Sneha Poondru, Theodore Thomas, Lee Ratner

2020-Current year OA Pubs

INTRODUCTION: Understanding of human T-lymphotropic virus (HTLV) remains largely based on epidemiologic and clinical data from endemic areas. Globalization has resulted in migration of persons living with HTLV (PLHTLV) from endemic to non-endemic areas, and a rise of HTLV infection in the United States. Yet, due to the historical rarity of this disease, affected patients are often under- and mis-diagnosed. Thus, we sought to characterize the epidemiology, clinical features, comorbidities, and survival of HTLV-1- or HTLV-2-positive individuals identified in a non-endemic area.

METHODS: Our study was a single institution, retrospective case-control analysis of HTLV-1 or HTLV-2 patients between 1998 and …
