Diabetes is a major risk factor for cardiovascular diseases, including diabetic cardiomyopathy, atherosclerosis, myocardial infarction, and heart failure. As cardiovascular disease represents the number one cause of death in people with diabetes, there has been a major emphasis on understanding the mechanisms by which diabetes promotes cardiovascular disease, and how antidiabetic therapies impact diabetic heart disease. With a wide array of models to study diabetes (both type 1 and type 2), the field has made major progress in answering these questions. However, each model has its own inherent limitations. Therefore, the purpose of this guidelines document is to provide the …

Free Silicone-Induced Granulomatosis And Hypercalcemia In A Transgender Female, Brian L. Pando, Benjamin Goldsmith, Adam Lane Webb, Komal Kinger, Brian Helmly

HCA Healthcare Journal of Medicine

Introduction

Vitamin D derangements are a rare but important cause of hypercalcemia. Granulomatous disease is a primary cause of vitamin D derangements and is frequently associated with sarcoidosis, tuberculosis, and in the present case, foreign body granulomatosis. Liquid or injectable silicone is used as a filler for cosmetic body contouring. Transgender patients may seek silicone injections as part of gender affirmation surgeries. Granuloma formation is a rare but well-described complication of injectable silicone.

Case Description

A 40-year-old, assigned male at birth (AMAB) transgender female patient, with a history of HIV and chronic kidney disease (CKD) stage 3b, was admitted to …

Regulation Of Age-Associated Insulin Resistance By Mt1-Mmp-Mediated Cleavage Of Insulin Receptor, Xuanming Guo, Pallavi Asthana, Susma Gurung, Shuo Zhang, Sheung Kin Ken Wong, Samane Fallah, Chi Fung Willis Chow, Sijia Che, Lixiang Zhai, Zening Wang, Xin Ge, Zhixin Jiang, Jiayan Wu, Yijing Zhang, Xiaoyu Wu, Keyang Xu, Cheng Yuan Lin, Hiu Yee Kwan, Aiping Lyu, Zhongjun Zhou, Zhao-Xiang Bian, Hoi Leong Xavier Wong

Insulin sensitivity progressively declines with age. Currently, the mechanism underlying age-associated insulin resistance remains unknown. Here, we identify membrane-bound matrix metalloproteinase 14 (MT1-MMP/MMP14) as a central regulator of insulin sensitivity during ageing. Ageing promotes MMP14 activation in insulin-sensitive tissues, which cleaves Insulin Receptor to suppress insulin signaling. MT1-MMP inhibition restores Insulin Receptor expression, improving insulin sensitivity in aged mice. The cleavage of Insulin Receptor by MT1-MMP also contributes to obesity-induced insulin resistance and inhibition of MT1-MMP activities normalizes metabolic dysfunctions in diabetic mouse models. Conversely, overexpression of MT1-MMP in the liver reduces the level of Insulin Receptor, impairing hepatic insulin …

Sinus Pauses And Asystole As A Rare Presentation Of Thyrotoxic Crisis: A Case Report, Christian Akem Dimala, Charnjeet Sandhu, Oreoluwa Oladiran, Agnieszka Mochon, William Finneran Iii

Transformative Medicine

Introduction

Thyroid crisis is a rare and life-threatening endocrine emergency characterized by exaggerated clinical manifestations of hyperthyroidism with cardiovascular manifestations being the most severe. Rhythm disturbances, sinus tachycardia and atrial fibrillation, are the commonest cardiac manifestations of severe thyrotoxicosis; however, asystole remains a very atypical and uncommon presentation. We present a case of thyrotoxicosis due to Grave’s disease complicated by multiple episodes of asystole.

Case Presentation

A 65-year-old female recently diagnosed with Grave’s disease presented to the hospital with recurrent episodes of syncope. Her hospital course was significant for atrial fibrillation with subsequent progression to sinus pauses and asystole spontaneously …

Severe To Very Severe Hypertriglyceridemia Management, Lauren Johnston, Rachel K. Bennings

2022 Providence Nurse Research Conference

Background: HTG-induced acute pancreatitis (HTG-IAP) is the third most common cause of pancreatitis, accounting for approximately 14% of cases. Knowing best care practices and having protocols to care for this patient population is imperative. Nurses working on the frontline of care noticed an increase in patients with HTG-IAP being admitted to their critical care unit, thus looking for an answer to how to best care for them became crucial. Nurses sought to find an answer to what evidence-based care delivery to this patient population is available in peer-reviewed literature.

Purpose/aims: Investigators sought to answer the question, “In adults (>18 …

The Association Between Fgf21 And Diabetic Erectile Dysfunction: Evidence From Clinical And Animal Studies, Song Yang, Yichun Zhang, Xiaohui Lyu, Yuanyuan Gu, Guodong Zhang, Pengcheng Liu, Yulu Zheng, Zheng Guo, Yanbo Zhang, Haifeng Hou

Research outputs 2022 to 2026

Erectile dysfunction (ED), a complication of diabetes mellitus (DM), affects 50–75% of men with diabetes. Fibroblast growth factor 21 (FGF21) is a liver-derived metabolic regulator which plays a role in insulin-independent glucose uptake in adipocytes. We designed a clinical study and an animal experiment to investigate the relationship between FGF21 and DM-induced ED. The clinical study enrolled 93 participants aged > 18 years (61 patients with type 2 DM and 32 healthy controls) from Taian City Central Hospital (TCCH) in Shandong Province, China, amongst whom the association between serum FGF21 and diabetic ED was analyzed. To further validate this association, we …

Tomatoes, Lycopene, And Prostate Cancer: What Have We Learned From Experimental Models?, Nancy E Moran, Jennifer M Thomas-Ahner, Lei Wan, Krystle E Zuniga, John W Erdman, Steven K Clinton

Children’s Nutrition Research Center Staff Publications

Human epidemiology suggests a protective effect of tomatoes or tomato phytochemicals, such as lycopene, on prostate cancer risk. However, human epidemiology alone cannot reveal causal relations. Laboratory animal models of prostate cancer provide opportunities to investigate hypotheses regarding dietary components in precisely controlled, experimental systems, contributing to our understanding of diet and cancer risk relations. We review the published studies evaluating the impact of tomatoes and/or lycopene in preclinical models of prostate carcinogenesis and tumorigenesis. The feeding of tomatoes or tomato components demonstrates anti-prostate cancer activity in both transplantable xenograft models of tumorigenesis and models of chemically- and genetically-driven carcinogenesis. …

Context Matters: Preliminary Evidence That The Association Between Positive Affect And Adiposity In Infancy Varies In Social Vs Non-Social Situations, Alexis C Wood, Shabnam R Momin, Mackenzie K Senn, David J Bridgett

Children’s Nutrition Research Center Staff Publications

Previous studies have suggested that infants high in negative affect have higher levels of adiposity, arising in part via changes in nutrition (e.g., “feeding to soothe”). Few studies have examined whether positive affect shows similar or inverse associations with adiposity. The current study examined cross-sectional and longitudinal relationships between adiposity and observations of positive affect in both a social and a non-social context, using data from infants at four (n = 125) and 12 (n = 80) months of age. Our analyses did not find any cross-sectional associations between positive affect and adiposity (all p > 0.05). However, in the longitudinal …

French-Fried Potato Consumption And Energy Balance: A Randomized Controlled Trial, Daniel L Smith, Rebecca L Hanson, Stephanie L Dickinson, Xiwei Chen, Amy M Goss, John B Cleek, W Timothy Garvey, David B Allison

Children’s Nutrition Research Center Staff Publications

Background: Epidemiologic observations suggest increased potato consumption correlates with weight gain, adiposity, and diabetes risk, whereas nut consumption is associated with weight control and metabolic health. Randomized controlled trial (RCT) data indicate humans respond to changes in energy intake in single dietary components and compensate for extra energy consumed.

Objectives: We completed an RCT testing whether increased daily potato consumption influences energy balance [specifically, fat mass (FM)] compared with calorie-matched almond consumption.

Methods: A 30-d RCT of 180 adults prescribed calorie-matched (300 kcal/d, n = 60 participants/group) than consumed 1 of the following: 1) almonds (almond group), 2) French fries …

Use Of Cgm In Monitoring Neonatal Diabetes, Emily Metzinger, Kelsee Halpin

Posters

Introduction Although continuous glucose monitoring (CGM) has increased in patients with Type 1 diabetes, its use in the neonatal population has remained limited. Neonates, particularly preterm infants, are at risk of impaired glucose control. Several studies have looked at the use of these devices in improving care for premature infants without diabetes. We describe a case of a very low birth infant with neonatal diabetes secondary to a GATA-6 mutation. Clinical Case This is a late preterm infant with IUGR, truncus arteriosus, and neonatal diabetes. Exome genetic panel showed a mutation in GATA-6. Her neonatal diabetes was challenging to control …

Exercise confers robust protection against obesity, type 2 diabetes, and other cardiometabolic diseases.1–5 However, the molecular and cellular mechanisms that mediate the metabolic benefits of physical activity remain unclear.6 Here we show that exercise stimulates production of Lac-Phe, a blood-borne signaling metabolite that suppresses feeding and obesity. Lac-Phe biosynthesis from lactate occurs in CNDP2+ cells including immune cells, epithelial cells, and mesenchymal stem cells localized to diverse organs. In diet-induced obese mice, pharmacological elevation of circulating Lac-Phe reduces food intake without affecting movement or energy expenditure. Chronic administration of Lac-Phe decreases adiposity and body weight and …

The Hypothalamus For Whole-Body Physiology: From Metabolism To Aging, Tiemin Liu, Yong Xu, Chun-Xia Yi, Qingchun Tong, Dongsheng Cai

Children’s Nutrition Research Center Staff Publications

Obesity and aging are two important epidemic factors for metabolic syndrome and many other health issues, which contribute to devastating diseases such as cardiovascular diseases, stroke and cancers. The brain plays a central role in controlling metabolic physiology in that it integrates information from other metabolic organs, sends regulatory projections and orchestrates the whole-body function. Emerging studies suggest that brain dysfunction in sensing various internal cues or processing external cues may have profound effects on metabolic and other physiological functions. This review highlights brain dysfunction linked to genetic mutations, sex, brain inflammation, microbiota, stress as causes for whole-body pathophysiology, arguing …

Children’s Nutrition Research Center Staff Publications

Background and aims: The DASH diet conveys protection against type 2 diabetes mellitus (T2D) Via plant-based and non-plant-based recommendations. Research has not identified which glucose homeostasis pathways are improved. We examined associations between adherence to a DASH diet and six glucose homeostasis traits, probing whether associations could be attributed to the plant-based (DASH-P) and/or non-plant based (DASH-NP) components.

Methods and results: We included data from 295 adults without T2D (age 59.3 ± 9.00 years; 63.46% non-Hispanic White and 36.54% African American, self-reported race ancestry) participating in the Microbiome and Insulin Longitudinal Evaluation Study (MILES). An oral glucose tolerance test (OGTT) …
