Diabetes-Related Bias In Electronic Health Records And International Classification Of Diseases., Mihail Zilbermint

Journal of Community Hospital Internal Medicine Perspectives

Diabetes mellitus is a chronic health condition that affects the body's ability to convert food into energy. People living with diabetes, as well as doctors and hospitals, struggle to handle the challenge. Among these challenges is that the field of diabetology is filled with bias. People living with diabetes will say that “diabetes does not define them,” yet they often refer to themselves as “diabetics.” Doctors are frequently “trained” to call people “diabetics,” and I am one of them. Psychological consequences associated with diabetes and obesity bias and stigma have been previously reported studied. People with diabetes may experience stigma …

Getting Ahead: A Resident Led Quality Improvement Project To Increase Diabetic Nephropathy Screening In An Underserved Hispanic-Predominant Population, Stephanie Luu, Jose Rivera, Daniel Aragon, Victor Zamora, Irma Huayanay, Reham Majzoub, Andreina Baird, Cristina Escobar, Eric Sanchez, Juan Carlos Lopez-Alvarenga, Daniela Hernandez, Chelsea Chang

Journal of Community Hospital Internal Medicine Perspectives

Introduction: Diabetes is the leading cause of end-stage renal disease (ESRD) in the United States (US), with 37 million having chronic kidney disease. Despite national guidelines recommendations for diabetic nephropathy screening with urine albumin-to-creatinine ratio (UACR), less than 50% receive full screening.

Our Internal Medicine residents led a quality improvement project to increase diabetic nephropathy screening rate with UACR in our resident clinic by 50% in one academic year.

Methods: We conducted the resident-led quality improvement project from July 2021 to April 2022. We reviewed the electronic medical records (EMR) from our clinic pre-intervention July 2020 to June 2021 and …

Children’s Nutrition Research Center Staff Publications

Background: Given that today's adolescents are digital front-runners, technology-based obesity prevention strategies are age-appropriate for this population. The use of remote and wireless technologies may be suitable for extending the reach and engagement of obesity prevention efforts among high-risk Hispanic youths, as this subgroup is disproportionately affected by barriers that limit participation in traditional, in-person interventions.

Objective: The purpose of this scoping review was to examine the intervention and sample characteristics of technology-based obesity prevention interventions among Hispanic adolescents. We also examined feasibility criteria to assess the acceptability and appropriateness of technology-based strategies among Hispanic youths.

Methods: A comprehensive search …

BACKGROUND

Cytochrome P450 family 8 subfamily B member 1 (CYP8B1) generates 12α-hydroxylated bile acids (BAs) that are associated with insulin resistance in humans.

METHODS

To determine whether reduced CYP8B1 activity improves insulin sensitivity, we sequenced CYP8B1 in individuals without diabetes and identified carriers of complete loss-of-function (CLOF) mutations utilizing functional assays.

RESULTS

Mutation carriers had lower plasma 12α-hydroxylated/non–12α-hydroxylated BA and cholic acid (CA)/chenodeoxycholic acid (CDCA) ratios compared with age-, sex-, and BMI-matched controls. During insulin clamps, hepatic glucose production was suppressed to a similar magnitude by insulin, but glucose infusion rates to maintain euglycemia were higher in mutation carriers, indicating …

Faculty, Staff and Student Publications

Prior studies have identified the associations between environmental phenol and paraben exposures and increased risk of gestational diabetes mellitus (GDM), but no study addressed these exposures as mixtures. As methods have emerged to better assess exposures to multiple chemicals, our study aimed to apply Bayesian kernel machine regression (BKMR) to evaluate the association between phenol and paraben mixtures and GDM. This study included 64 GDM cases and 237 obstetric patient controls from the University of Oklahoma Medical Center. Mid-pregnancy spot urine samples were collected to quantify concentrations of bisphenol A (BPA), benzophenone-3, triclosan, 2,4-dichlorophenol, 2,5-dichlorophenol, butylparaben, methylparaben, and propylparaben. Multivariable …

Molecular Mechanisms Of Resistance To Kinase Inhibitors And Redifferentiation In Thyroid Cancers, Marie-Claude Hofmann, Muthusamy Kunnimalaiyaan, Jennifer R Wang, Naifa L Busaidy, Steven I Sherman, Stephen Y Lai, Mark Zafereo, Maria E Cabanillas

Protein kinases play critical roles in cell survival, proliferation and motility. Their dysregulation is therefore a common feature in the pathogenesis of a number of solid tumors, including thyroid cancers. Inhibiting activated protein kinases has revolutionized thyroid cancer therapy, offering a promising strategy in treating tumors refractory to radioactive iodine treatment or cytotoxic chemotherapies. However, despite satisfactory early responses, these drugs are not curative and most patients inevitably progress due to drug resistance. This review summarizes up-to-date knowledge on various mechanisms that thyroid cancer cells develop to bypass protein kinase inhibition and outlines strategies that are being explored to overcome …

A Subpopulation Of Oxytocin Neurons Initiate Expression Of Crf Receptor 1 (Crfr1) In Females Post Parturition, Lierni Ugartemendia, Rose M De Guzman, Jing Cai, Shivakumar Rajamanickam, Zhiying Jiang, Jonathan Tao, Damian G Zuloaga, Nicholas J Justice

Faculty, Staff and Student Publications

Oxytocin (OT) is essential for successful reproduction, particularly during parturition and lactation. During the postpartum period, OT also influences maternal behavior to promote bonding between mothers and their newborns, and increases stress resilience. However, the mechanism by which stress influences OT neuron activity and OT release has remained unclear. Here, we provide evidence that a subpopulation of OT neurons initiate expression of the receptor for the stress neuropeptide Corticotropin Releasing Factor (CRF), CRFR1, in reproductive females. OT neuron expression of CRFR1 begins at the first parturition and increases during the postpartum period until weaning. The percentage of OT neurons that …

Type 1 diabetes is a complex disease characterized by the lack of endogenous insulin secreted from the pancreatic β-cells. Although β-cell targeted autoimmune processes and β-cell dysfunction are known to occur in type 1 diabetes, a complete understanding of the cell-to-cell interactions that support pancreatic function is still lacking. To characterize the pancreatic endocrine compartment, we studied pancreata from healthy adult donors and investigated a single cell surface adhesion molecule, desmoglein-2 (DSG2). Genetically-modified mice lacking Dsg2 were examined for islet cell mass, insulin production, responses to glucose, susceptibility to a streptozotocin-induced mouse model of hyperglycaemia, and ability to cure diabetes …

Accounting For The Clustering And Nesting Effects Verifies Most Conclusions Corrected Analysis Of: “Randomized Nutrient Bar Supplementation Improves Exercise-Associated Changes In Plasma Metabolome In Adolescents And Adult Family Members At Cardiometabolic Risk”, Yasaman Jamshidi-Naeini, Lilian Golzarri-Arroyo, Colby J Vorland, Andrew W Brown, Stephanie Dickinson, David B Allison

In a published randomized controlled trial, household units were randomized to a nutrient bar supplementation group or a control condition, but the non-independence of observations within the same household (i.e., the clustering effect) was not accounted for in the statistical analyses. Therefore, we reanalyzed the data appropriately by adjusting degrees of freedom using the between-within method, and accounting for household units using linear mixed effect models with random intercepts for family units and subjects nested within family units for each reported outcome. Results from this reanalysis showed that ignoring the clustering and nesting effects in the original analyses had resulted …

Modern Therapeutic Options In Diabetic Foot Ulcer, Denisa Tanasescu, Andrei Moisin, Radu Fleaca, Carmen Popa, Ciprian Bacila, Cosmin Mohor, Claudia Diana Gherman, Bogdan Gaspar, Ciprian Tanasescu

Journal of Mind and Medical Sciences

Diabetic foot is a severe complication of diabetes that occurs as a result of poor glycemic control, being associated with significant morbidity and mortality. Mortality associated with this disease is estimated at 5% in the first 12 months, and about 42% in the next 5 years. On average, it affects about 15% of people with diabetes during their lifetime, including as possible manifestations neuropathy, peripheral vascular disease, and subsequent ulceration which, if treated incorrectly, can lead to amputation.

This paper presents a retrospective and descriptive study of patients diagnosed and treated for diabetic foot ulcers in the Proctoven Clinic. The …

Eating Disorders In Men: A Comprehensive Summary, Connor James Spratt, Liam Alexander Mackenzie Myles, Emanuele Maria Merlo

Journal of Mind and Medical Sciences

Eating disorders (EDs) have detrimental effects on an individual’s physical and mental health, along with significant interpersonal, social and economic effects. Furthermore, men who are suffering with an ED face unique challenges with this. Men suffering with EDs have historically received little attention within ED research, diagnosis and intervention. However, the number of men suffering with these issues is significant and growing. Understanding of EDs tend to ignore male experiences, meaning many are left to suffer in silence until the ED has developed to a critical point. However, many now recognize the need to understand the issues facing men suffering …

Children’s Nutrition Research Center Staff Publications

Objective: Although mood and anxiety symptoms are common in youth with type 1 diabetes (T1D), little research has described their worries across developmental stages or the strategies they use to cope with these worries. This secondary data analysis aimed to describe and characterize common T1D-related worries and coping strategies from middle childhood through young adulthood.

Methods: Twenty-three youth (9 children, 7 adolescents, and 7 young adults) completed semistructured qualitative interviews about health-related quality of life. We coded interview transcripts using thematic analysis to generate common themes of diabetes-related worries and coping strategies.

Results: Participants' worries fell into four major themes: …

Physicians’ Considerations And Practice Recommendations Regarding The Use Of Sodium-Glucose Cotransporter-2 Inhibitors, Serge A. Jabbour, Nasrien E. Ibrahim, Christos P. Argyropoulos

Division of Endocrinology, Diabetes and Metabolic Diseases Faculty Papers

Sodium-glucose cotransporter-2 inhibitors (SGLT-2is) (canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin), although initially developed as glucose-lowering drugs, provide significant beneficial effects on cardiorenal outcomes, including heart failure, regardless of type 2 diabetes status. Integration of SGLT-2is into clinical practice requires practical guidance for physicians about their use. To overcome physicians’ clinical inertia for SGLT-2i use, including addressing safety, potentially a barrier to their use, a roundtable discussion with physicians from three specialties (cardiology, endocrinology, and nephrology) was conducted. This review summarizes the physicians’ clinical experience and recommendations about SGLT-2i use across different patient populations, taking into consideration the beneficial effects of SGLT-2is …
