Aims/hypothesis: Insulin resistance and compensatory hyperinsulinaemia are core features leading to beta cell failure in youth-onset type 2 diabetes. Insulin clearance (IC) is also a key regulator of insulin concentrations, but few data exist on IC in youth-onset type 2 diabetes. In a secondary analysis of our Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) randomised clinical trial, we investigated potential sex-, race-, ethnicity- and treatment-related differences in IC in youth-onset type 2 diabetes and aimed to identify metabolic phenotypes associated with IC at baseline and in response to metformin, metformin plus a lifestyle intervention, and metformin …

Center on Aging Staff Publications

The endolysosomal system plays a crucial role in maintaining cellular homeostasis and promoting organism fitness. The pH of its acidic compartments is a crucial parameter for proper function, and it is dynamically influenced by both intracellular and environmental factors. Here, we present a method based on fluorescence lifetime imaging microscopy (FLIM) for quantitatively analyzing the pH profiles of acidic endolysosomal compartments in diverse types of primary mammalian cells and in live organism Caenorhabditis elegans. This FLIM-based method exhibits high sensitivity in resolving subtle pH differences, thereby revealing heterogeneity within a cell and across cell types. This method enables rapid …

Ethical Considerations Of Percutaneous Endoscopic Gastrostomy Tube Placement In A Patient With Creutzfeldt-Jakob Disease And Advanced Dementia, Toni Habib, Niamh Siobhán Mulrooney, Yisroel Grabie, Mohammad Maruf, Sophia Kasapira

HCA Healthcare Journal of Medicine

Background

Creutzfeldt-Jakob disease (CJD) is a rapidly progressive neurodegenerative condition that is not easily diagnosed and has no curative treatments available, essentially requiring palliative measures, including tube feeding. Nonetheless, data shows that the endoscope used for percutaneous endoscopic gastrostomy (PEG) tube insertion can be a vector for CJD transmission.

Case Presentation

We discuss the case of an elderly patient diagnosed with CJD, requiring tube feeding. Multiple specialists were consulted, and they were unable to reach an agreement on the best approach. Eventually, the hospital ethics committee intervened, and the family agreed to comfort measures only. This case report sheds light …

Anterior cruciate ligament (ACL) injury adversely affects skeletal muscle, leading to muscle atrophy and weakness, significantly impacting clinical outcomes. This study aimed to determine if estrogen-related receptor gamma (ERRγ) overexpression in skeletal muscle could mitigate muscle atrophy after ACL injury. An animal model with selective overexpression of ERRγ in skeletal muscle (ERR-gamma transgenic mice, TG) and WT control mice were used for this study. All the mice received a mechanical ACL rupture and were euthanized at 4- and 8-week post-injury. Muscle histology, atrophy, and function were evaluated and compared between the TG and WT mice. Muscle-specific ERRγ activation in TG …

In critical illness, all elements of gut function are perturbed. Dysbiosis develops as the gut microbial community loses taxonomic diversity and new virulence factors appear. Intestinal permeability increases, allowing for translocation of bacteria and/or bacterial products. Epithelial function is altered at a cellular level and homeostasis of the epithelial monolayer is compromised by increased intestinal epithelial cell death and decreased proliferation. Gut immunity is impaired with simultaneous activation of maladaptive pro- and anti-inflammatory signals leading to both tissue damage and susceptibility to infections. Additionally, splanchnic vasoconstriction leads to decreased blood flow with local ischemic changes. Together, these interrelated elements of …

Human noroviruses (HuNoVs) are the leading cause of acute gastroenteritis worldwide. Currently, there are no targeted antivirals for the treatment of HuNoV infection. Histo-blood group antigens (HBGAs) on the intestinal epithelium are cellular attachment factors for HuNoVs; molecules that block the binding of HuNoVs to HBGAs thus have the potential to be developed as antivirals. Human milk oligosaccharides (HMOs) are glycans in human milk with structures analogous to HBGAs. HMOs have been shown to act as decoy receptors to prevent the attachment of multiple enteric pathogens to host cells. Previous X-ray crystallography studies have demonstrated the binding of HMO 2′-fucosyllactose …

Protein Serine Kinase H1 (PSKH1) was recently identified as a crucial factor in kidney development and is overexpressed in prostate, lung, and kidney cancers. However, little is known about PSKH1 regulatory mechanisms, leading to its classification as a “dark” kinase. Here, we used biochemistry and mass spectrometry to define PSKH1’s consensus substrate motif, protein interactors, and how interactors, including Ca2+ sensor proteins, promote or suppress activity. Intriguingly, despite the absence of a canonical Calmodulin binding motif, Ca2+-Calmodulin activated PSKH1 while, in contrast, the ER-resident Ca2+ sensor of the Cab45, Reticulocalbin, Erc55, Calumenin (CREC) family, Reticulocalbin-3, suppressed PSKH1 catalytic activity. In …

Treatment with antibiotics is a major risk factor for Clostridioides difficile infection, likely due to depletion of the gastrointestinal microbiota. Two microbiota-mediated mechanisms thought to limit C. difficile colonization include the conversion of conjugated primary bile salts into secondary bile salts toxic to C. difficile growth and competition between the microbiota and C. difficile for limiting nutrients. Using a continuous flow model that simulates the nutrient conditions of the distal colon, we investigated how treatment with 6 clinically used antibiotics influenced susceptibility to C. difficile infection in 12 different microbial communities cultivated from healthy individuals. Antibiotic treatment reduced microbial richness; …

Division of Endocrinology, Diabetes and Metabolic Diseases Faculty Papers

Human growth hormone (hGH) has been in clinical use for children with GH deficiency (GHD) since the late 1950s. The original formulations were considered very safe with few adverse events reported. That changed remarkably in 1985 when the first patients with GHD, who had been treated with cadaveric hGH, were diagnosed with Creutzfeldt-Jakob disease (CJD). Fortunately, that same year a robust supply of recombinant hGH was released to the market whose adverse event profile did not include CJD. Patients who had received National Hormone and Pituitary Program hGH have been continuously followed since 1985. It is clear that prions are …

Epstein-Barr virus (EBV) is strongly associated with the development of post-transplant lymphoproliferative disorder (PTLD) in pediatric liver transplant recipients. PTLD is one of the most common malignancies following liver transplantation and is associated with significant morbidity and mortality. Factors such as EBV-serostatus mismatch and prolonged or high levels of immunosuppression impact a patient's risk of developing PTLD. While pre-transplant EBV serological screening and post-transplant monitoring of EBV-DNA levels are strongly recommended, universal guidelines for its prevention and management are lacking. Due to a lack of robust prospective studies, current clinical practices vary widely. The treatment of PTLD typically involves reducing …

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the leading cause of chronic liver disease and is associated with significant cardiovascular morbidity and mortality. This study aims to investigate the association of glucagon-like peptide-1 (GLP-1) agonists with major cardiovascular events, clinically significant portal hypertension events, and all-cause mortality in patients with MASLD. A large, population-based retrospective cohort study was conducted using the TriNetX platform, which provided real-time access to electronic health records of 634,265 adult patients with MASLD/MASH. Propensity score matching (PSM) was employed to create two cohorts: A GLP-1 agonists group and a control group without GLP-1 agonists usage. Hazard …

Quantifying emesis in Suncus murinus (S. murinus) has traditionally relied on direct observation or reviewing recorded behaviour, which are laborious, time-consuming processes that are susceptible to operator error. With rapid advancements in deep learning, automated animal behaviour quantification tools with high accuracy have emerged. In this study, we pioneere the use of both three-dimensional convolutional neural networks and self-attention mechanisms to develop the Automatic Emesis Detection (AED) tool for the quantification of emesis in S. murinus, achieving an overall accuracy of 98.92%. Specifically, we use motion-induced emesis videos as training datasets, with validation results demonstrating an accuracy of 99.42% for …

PURPOSE OF REVIEW: Hypertension (HTN) is a major risk factor for cardiovascular diseases (CVD). The global prevalence of HTN and related CVD mortality continues to rise. The development of HTN is influenced by genetic predisposition and modifiable risk factors, including diet. One area of ongoing debate is the relationship between red meat consumption and risk of HTN.

RECENT FINDINGS: Processed red meat has become increasingly implicated in the pathogenesis and morbidity of HTN, though randomized control trials comparing HTN-related outcomes associated with red meat subtypes have yielded heterogenous results. This review summarizes the existing relevant literature and highlights the methodological …
