Diabetes mellitus presents an increasing prevalence and severe multisystemic complications, with notable personal, professional and social implications. Diabetes is generally known by hyperglycemia and subsequent metabolic disorders. In addition to hyperglycemia, it appears that other factors (related to anthropometric-pathophysiology and genome-based subphenotyping) are involved not only in the clinical course but also in the occurrence of diabetes complications. This review presents several diabetes-induced complications on the digestive tract (periodontal disease, xerostomia, oral infections, dental caries, taste disturbances, gastroesophageal reflux disease, gastroparesis, gastric ulcer and cancer, diabetic enteropathy, inflammatory bowel diseases, colorectal cancer, etc.), many of them with major implications and …

Giant Adrenal Myelolipomas: A Literature Review, Mircea Hogea, Anda Hogea, Marius Moga, Roxana Dragomir, Simona Grigorescu, Bogdan Socea

Journal of Mind and Medical Sciences

Myelolipomas are described as small tumors, with some authors referring to sizes less than 4 cm in diameter. However, when greater than 10 cm, myelolipomas are labeled as giant tumors and thus, have a definite indication for surgical resection. Myelolipomas represent a small percentage of adrenal tumors. Giant myelolipomas are usually discovered incidentally during imaging studies performed for other conditions. They are often slow-growing and may reach sizes that significantly distort the anatomy of the affected area. Despite their large size, they are usually benign and do not spread to other parts of the body. Adrenal myelolipoma is a benign …

Hidden: A Baker's Dozen Ways In Which Research Reporting Is Less Transparent Than It Could Be And Suggestions For Implementing Einstein's Dictum, Abu Bakkar Siddique, Brian Shaw, Johanna Dwyer, David A Fields, Kevin Fontaine, David Hand, Randy Schekman, Jeffrey Alberts, Julie Locher, David B Allison

The tutelage of our mentors as scientists included the analogy that writing a good scientific paper was an exercise in storytelling that omitted unessential details that did not move the story forward or that detracted from the overall message. However, the advice to not get lost in the details had an important flaw. In science, it is the many details of the data themselves and the methods used to generate and analyze them that give conclusions their probative meaning. Facts may sometimes slow or distract from the clarity, tidiness, intrigue, or flow of the narrative, but nevertheless they are important …

Reproduction Has Immediate Effects On Female Mortality, But No Discernible Lasting Physiological Impacts: A Test Of The Disposable Soma Theory, Sharon E Mitchell, Megan Simpson, Lena Coulet, Solenn Gouedard, Catherine Hambly, Juliano Morimoto, David B Allison, John R Speakman

Children’s Nutrition Research Center Staff Publications

The disposable soma theory (DST) posits that organisms age and die because of a direct trade-off in resource allocation between reproduction and somatic maintenance. DST predicts that investments in reproduction accentuate somatic damage which increase senescence and shortens lifespan. Here, we directly tested DST predictions in breeding and nonbreeding female C57BL/6J mice. We measured reproductive outputs, body composition, daily energy expenditure, and oxidative stress at peak lactation and over lifetime. We found that reproduction had an immediate and negative effect on survival due to problems encountered during parturition for some females. However, there was no statistically significant residual effect on …

Severe and chronic infections, including pneumonia, sepsis, and tuberculosis (TB), induce long-lasting epigenetic changes that are associated with an increase in all-cause postinfectious morbidity and mortality. Oncology studies identified metabolic drivers of the epigenetic landscape, with the tricarboxylic acid (TCA) cycle acting as a central hub. It is unknown if the TCA cycle also regulates epigenetics, specifically DNA methylation, after infection-induced immune tolerance. The following studies demonstrate that lipopolysaccharide and Mycobacterium tuberculosis induce changes in DNA methylation that are mediated by the TCA cycle. Infection-induced DNA hypermethylation is mitigated by inhibitors of cellular metabolism (rapamycin, everolimus, metformin) and the TCA …

Thyrotoxicosis is a systemic condition caused by the effects of elevated levels of thyroid hormones. The cardiovascular manifestations of thyrotoxicosis range from sinus tachycardia and atrial fibrillation to heart failure. The incidence of malignant arrhythmias and cardiac arrest associated with thyrotoxicosis is not well known, and much of the current literature regarding this is limited to case reports. This study conducts a systematic review of the literature to identify patient demographics and outcomes where thyrotoxicosis manifests as cardiac arrest.

Predicting The Pathway Involvement Of All Pathway And Associated Compound Entries Defined In The Kyoto Encyclopedia Of Genes And Genomes, Erik D. Huckvale, Hunter Moseley

Markey Cancer Center Faculty Publications

Background/Objectives: Predicting the biochemical pathway involvement of a compound could facilitate the interpretation of biological and biomedical research. Prior prediction approaches have largely focused on metabolism, training machine learning models to solely predict based on metabolic pathways. However, there are many other types of pathways in cells and organisms that are of interest to biologists. Methods: While several publications have made use of the metabolites and metabolic pathways available in the Kyoto Encyclopedia of Genes and Genomes (KEGG), we downloaded all the compound entries with pathway annotations available in the KEGG. From these data, we constructed a dataset where each …

Pulmonary Vascular Manifestations Of Hereditary Haemorrhagic Telangiectasia, Sarah Cullivan, Barry Kevane, Brian Mccullagh, Terry M O'Connor, Robin Condliffe, Sean Gaine

Children’s Nutrition Research Center Staff Publications

Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant, multisystem disorder that manifests with a spectrum of disease including cardiopulmonary complications. HHT is characterised by aberrant signalling via the transforming growth factor β (TGFβ) pathway, with loss of vascular integrity, angiogenesis and vascular dysplasia. The disease has an estimated prevalence of 1 in 5000 persons and the penetrance increases with increasing age. HHT commonly presents with epistaxis and telangiectasia, while visceral arteriovenous malformations are not uncommon. Mutations in the ENG, ACVRL1 and MADH4 genes account for 97% of all HHT cases, and it is recommended that genetic tests are used in …

Benefits Of Calorie Restriction In Mice Are Mediated Via Energy Imbalance, Not Absolute Energy Or Protein Intake, Daniel L Smith, Sharon E Mitchell, Maria S Johnson, Victoria K Gibbs, Stephanie Dickinson, Beate Henschel, Rui Li, Kathryn A Kaiser, Daniella E Chusyd, Andrew W Brown, David B Allison, John R Speakman, Tim R Nagy

Caloric restriction (CR) results in reduced energy and protein intake, raising questions about protein restriction's contribution to CR longevity benefits. We kept ad libitum (AL)-fed male C57BL/6J mice at 27°C (AL27) and pair-fed (PF) mice at 22°C (22(PF27)). The 22(PF27) group was fed to match AL27 while restricted for calories due to cold-induced metabolism. The 22(PF27) mice had significantly lower body weight, lean mass, fat mass, leptin, IGF-1, and TNF-α levels than AL27 mice (p< 0.001 for all). Manipulations over ~11 weeks resulted in significant differences in body temperature, physical activity, and expression of key genes linked to hunger in the hypothalamus. Survival was significantly greater in 22(PF27) compared to AL27 overall (p< 0.001). CR in the context of equivalent energy and protein intake resulted in hormonal, metabolic, and physiological benefits and extended longevity. Hence, energy imbalance, rather than low energy or protein intake per se, mediates the benefits of CR.

The exponential rise in metabolic dysfunction-associated steatotic liver disease (MASLD) parallels the ever-increasing consumption of energy-dense diets, underscoring the need for effective MASLD-resolving drugs. MASLD pathogenesis is linked to obesity, diabetes, "gut-liver axis" alterations, and defective interleukin-22 (IL-22) signaling. Although barrier-protective IL-22 blunts diet-induced metabolic alterations, inhibits lipid intake, and reverses microbial dysbiosis, obesogenic diets rapidly suppress its production by small intestine-localized innate lymphocytes. This results in STAT3 inhibition in intestinal epithelial cells (IECs) and expansion of the absorptive enterocyte compartment. These MASLD-sustaining aberrations were reversed by administration of recombinant IL-22, which resolved hepatosteatosis, inflammation, fibrosis, and insulin resistance. Exogenous …

The spectrum of cardiorenal and metabolic diseases comprises many disorders, including obesity, type 2 diabetes (T2D), chronic kidney disease (CKD), atherosclerotic cardiovascular disease (ASCVD), heart failure (HF), dyslipidemias, hypertension, and associated comorbidities such as pulmonary diseases and metabolism dysfunction-associated steatotic liver disease and metabolism dysfunction-associated steatohepatitis (MASLD and MASH, respectively, formerly known as nonalcoholic fatty liver disease and nonalcoholic steatohepatitis [NAFLD and NASH]). Because cardiorenal and metabolic diseases share pathophysiologic pathways, two or more are often present in the same individual. Findings from recent outcome trials have demonstrated benefits of various treatments across a range of conditions, suggesting a need …

Stareg: Statistical Replicability Analysis Of High Throughput Experiments With Applications To Spatial Transcriptomic Studies, Yan Li, Xiang Zhou, Rui Chen, Xianyang Zhang, Hongyuan Cao

Faculty, Staff and Students Publications

Replicable signals from different yet conceptually related studies provide stronger scientific evidence and more powerful inference. We introduce STAREG, a statistical method for replicability analysis of high throughput experiments, and apply it to analyze spatial transcriptomic studies. STAREG uses summary statistics from multiple studies of high throughput experiments and models the the joint distribution of p-values accounting for the heterogeneity of different studies. It effectively controls the false discovery rate (FDR) and has higher power by information borrowing. Moreover, it provides different rankings of important genes. With the EM algorithm in combination with pool-adjacent-violator-algorithm (PAVA), STAREG is scalable to datasets …
