Diabetes-Associated Hyperglycemia Causes Rapid-Onset Ocular Surface Damage, Judy Weng, Christopher Ross, Jacob Baker, Saleh Alfuraih, Kiumars Shamloo, Ajay Sharma

Pharmacy Faculty Articles and Research

Purpose: The metabolic alterations due to chronic hyperglycemia are well-known to cause diabetes-associated complications. Short-term hyperglycemia has also been shown to cause many acute changes, including hemodynamic alterations and osmotic, oxidative, and inflammatory stress. The present study was designed to investigate whether diabetes-associated hyperglycemia can cause rapid-onset detrimental effects on the tear film, goblet cells, and glycocalyx and can lead to activation of an inflammatory cascade or cellular stress response in the cornea.

Methods: Mouse models of type 1 and type 2 diabetes were used. Tear film volume, goblet cell number, and corneal glycocalyx area were measured on …

Examining The Effects Of Hyperglycemia On Retinal Regeneration, Emmanuella Ec Kyllians

Theses and Dissertations--Biology

Diabetes is a disease that affects how the body processes glucose, leading to a cascade of other complications, one of which is diabetic retinopathy (DR). DR is a neurovascular disease that affects the retina and research has revealed the role of retinal neurodegeneration in its development. Animal models like zebrafish have emerged as important tools for studying the molecular and cellular mechanisms underlying DR. On the other hand, retinitis pigmentosa (RP) is a degenerative disease that involves the progressive degeneration of rods and cones, and hyperglycemia has been found to impair regeneration. Therefore, this study aims to examine the effects …

Establishment Of An In Vivo Streptozotocin-Induced Type 1 Diabetes Model Recapitulating Early Brain And Retinal Fibrosis, Kia Bourdot, Lucy Dawson, Igor Kuzin, Arturo Bravo Nuevo, Zeus Antonello

Cooper Rowan Medical Journal

INTRODUCTION: Diabetes has risen to one of the top American public health concerns. The hyperglycemic state of chronic diabetes leads to microvascular and macrovascular changes that predispose patients to delayed wound healing and organ fibrosis. The validation of models to specifically detect early, quantifiable fibrotic changes seen in the diabetic state is of fundamental importance for understanding the diabetic pathophysiology and exploring earlier management options. Here, we investigated if we could detect early signs of internal fibrosis in a streptozotocin (STZ) diabetic mouse model by quantifying α-SMA expression in various organs using flow cytometry.

METHODS: We used a low-dose STZ-induced …

Case Report: Pheochromocytoma Presenting With Cushing’S Syndrome And Hyperglycemia, Elizabeth Garbitelli, Halla Bates, Cheryl Liechty, Robert Bing-You

Journal of Maine Medical Center

Introduction: Pheochromocytomas are catecholamine-producing neuroendocrine tumors that arise from the adrenal medulla. Pheochromocytomas typically present with uncontrollable or paroxysmal hypertension that can be accompanied by other common initial symptoms, including headache, diaphoresis, arrhythmia, and pallor. Given the morbidity and mortality associated with undiagnosed pheochromocytomas, and their potential for treatment, primary care physicians should consider this tumor type, and other endocrinological phenomena, when evaluating new onset hyperglycemia.

Clinical Findings: Patient G was a 76-year-old female who presented in her primary care office with newly uncontrollable hyperglycemia. During initial evaluation, her clinical condition deteriorated rapidly. Her laboratory studies revealed markedly elevated cortisol, …

Hyperglycemia During The First Three Days Of Life Increases The Risk Of Retinopathy Of Prematurity In Extremely Low Birth Weight Infants, Jihan M. Esmail, Ramasubbareddy Dhanireddy Md

Longitudinal Scholar's Project

Background: The association between hyperglycemia and ROP has been inconsistent in previous studies. Extremely low birth weight (ELBW) infants are at high risk for ROP. They also experience hypoglycemia initially and hyperglycemia while receiving IV glucose infusion. The effect of initial hypoglycemia on hyperglycemia associated ROP risk is unknown.

Objective: To study the effect of initial hypoglycemia and subsequent hyperglycemia during the first three days of life on the incidence of ROP and severe ROP in ELBW (birth weight ≤1000g) infants.

Methods: Clinical and demographic data were collected from 227 ELBW infants born during the years 2017-2019 at the Regional …

Fda Approves New Inhaled Insulin: Afrezza® (Technosphere® Insulin), Benjamin Finley, Christina Ciccone, Kimberly Loughlin, Michelle Musser

Pharmacy and Wellness Review

Diabetes is an endocrine disease caused by deficiency or malfunction of insulin that results in high blood glucose levels and places patients at higher risk for a number of complications. This chronic disease is difficult to manage and affects millions of people in the United States, costing the health care system billions of dollars a year. Of a variety of antidiabetic agents used to control blood glucose, insulin is perhaps the most effective, but until recently it was only available in injectable form. As of June 27, 2014, a new inhaled insulin called Afrezza® (Technosphere® insulin) was approved by the …

Treatment Of Pasireotide Lar-Associated Hyperglycemia In A Patient With Acromegaly, Cheryl Rosenfeld

Touro College of Osteopathic Medicine (Middletown) Publications and Research

Objective: Hyperglycemia was noted in pasireotide long-acting release (PAS LAR}-treated patients with acromegaly during clinical trials. We describe a clinical approach to hyperglycemia in a patient with acromegaly and diabetes mellitus type 2 (DM2) during PAS LAR initiation and treatment.

Methods: Clinical response to PAS LAR, including self­ monitored blood glucose (SMBG) levels, HbA1c, IGF-1, and adverse effects, was reported. Case Presentation: A 44-year-old male was referred for consultation in 2007 owing to uncontrolled DM2 despite maximum metformin (MET) dose. Testing led to a biochemical diagnosis of acromegaly. An 8-mm pituitary adenoma was seen on MRI. Transsphenoidal pituitary adenoma …

Effects Of Nox-1 Inhibition On Real-Time Blood Nitric Oxide And Hydrogen Peroxide In Acute Hyperglycemia, Ashley Mawhinney

PCOM Biomedical Studies Student Scholarship

Hyperglycemia has been associated with vascular endothelial dysfunction in part by a reduction in nitric oxide (NO) production and increased oxidative stress (e.g., increased superoxide (SO) and hydrogen peroxide (H₂O₂). Endothelial-derived NO can be significantly reduced by increased SO/H₂O₂ in part by the activation of NADPH oxidase during hyperglycemia. Of the 7 NADPH oxidase isoforms, NADPH oxidase isoform 1 (NOX1) is mainly expressed in the vasculature and may play a major role in hyperglycemia induced oxidative stress and vascular endothelial dysfunction. This hypothesis was tested by measuring blood NO and H2O2 levels in …

Insulin Resistance Due To Obesity, Chasity Crist

Nursing Student Class Projects (Formerly MSN)

Diabetes is defined as a common metabolic disorder where hyperglycemia or elevated glucose levels are prevalent (Shah & Vella, 2014). The most common form of diabetes is type two diabetes (T2DM) and effects around 9.3% of the population in the United States (Cornell, 2015, p. 631). The pathophysiology of this disease includes involvement from the pancreas, liver, skeletal muscle, adipose tissue, gastrointestinal tract, brain, and kidneys. Hyperglycemia is high blood sugar levels that effects multiple organs (Rymaszewski & Breakwell, 2013). Protocols are developed to allow nurses to identify and treat hyper/hypoglycemia. Patient education is a direct impact of the long …

Diabetic Ketoacidosis, Mario Bianconi

Nursing Student Class Projects (Formerly MSN)

According to “Statistics About Diabetes” (2014), in 2012, 29.1 million Americans, or 9.3% of the population, had diabetes. Additionally, of the 29.1 million, 21 million of the population were diagnosed, and 8.1 million were undiagnosed. With such a high prevalence, it is imperative that the hospital nurse is aware not only how to treat diabetes, but also how to look for complications of diabetes. One of the severe complications of diabetes is Diabetic Ketoacidosis, or DKA. DKA occurs as a result of prolonged untreated diabetes. It is the result of the body not being able to produce, or use, insulin …
