Background: The benefit of adjuvant chemotherapy (AC) for ampullary adenocarcinoma is unclear. The Hidden Genome model classifies prognostic subtypes with greater accuracy than standard histologic classification (intestinal [INT] vs pancreatobiliary [PB]), but its predictive capacity to guide the use of AC remains unstudied.

Methods: We applied the Hidden Genome model to an international cohort of 183 patients with resected ampullary adenocarcinoma who underwent genomic sequencing. The model quantified the predicted cell of origin (colorectal vs pancreas/distal bile duct) in all specimens. Overall survival (OS) was compared using Kaplan-Meier estimates, stratified by AC use versus surgery alone (SA).

Results: Most patients …

Bile Acid Regulation Of Xenobiotic Nuclear Receptors On The Expressions Of Orosomucoids In The Liver, Ji Ho Suh, Inyoung Cheon, Hyun-Jung Jung, Sung Ho Lee, Mi Jeong Heo, Matthew Deberge, Clavia Ruth Wooton-Kee, Kang Ho Kim

Children’s Nutrition Research Center Staff Publications

The constitutive androstane receptor (CAR) and pregnane X receptor (PXR) are xenobiotic nuclear receptors activated by various xenobiotics, drugs, hormones, and bile acids (BAs). Upon activation, these nuclear receptors play critical roles in regulating systemic energy homeostasis. However, precise mechanisms through which CAR and PXR influence systemic metabolism remain incompletely understood. Here, we investigated the impact of CAR and PXR on the liver-secreted hormone (i.e., hepatokine) expressions in response to BA stress such as cholic acid (CA) feeding. Our analysis revealed that several BA-activated genes, including the well-known CAR/PXR target, aldo-keto reductase family 1, member B7 (Akr1b7 …

Changes In The Fxr-Cistrome And Alterations In Bile Acid Physiology In Wilson Disease, Clavia Ruth Wooton-Kee, Hari K Yalamanchili, Islam Mohamed, Manal Hassan, Kenneth D R Setchell, Monica Narvaez Rivas, Ayse K Coskun, Vasanta Putluri, Nagireddy Putluri, Prasun Jalal, Michael L Schilsky, David D Moore

Background: Wilson disease (WD) is an autosomal recessive disorder that results in excessive hepatic copper, causing hepatic steatosis, inflammation, fibrosis, cirrhosis, and liver failure. Previous studies have revealed dysregulation of many farnesoid X receptor (FXR) metabolic target genes in WD, including the bile salt exporter pump, the major determinant of bile flow.

Methods: We tested the hypothesis that the FXR-cistrome is decreased in Atp7b-/- mice in accord with dysregulated bile acid homeostasis.

Results: FXR binding within Atp7b-/- mouse livers displayed surprising complexity: FXR binding was increased in distal intergenic regions but decreased in promoter regions in Atp7b-/- versus wild-type mice. …

Objective: The long-term durability of improvements in functional mobility and musculoskeletal pain for adolescents after metabolic and bariatric surgery (MBS) is unknown.

Methods: We used the Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) study to determine the change in mobility and pain among adolescents who underwent MBS. From standardized 400-m walk tests, we analyzed walk time, heart rate (HR) parameters, and musculoskeletal pain.

Results: The mean walk time improved from 383 s (95% CI: 368-399) prior to surgery to 351 s (95% CI: 330-372) by 6 years. The mean resting HR was 90 beats per minute (bpm; 95% CI: 87-93) preoperatively …

Severe Gastrointestinal Manifestations In Childhood-Onset Lupus: A Single-Center Cohort And Review Of The Literature, James Orozco, Jessica Nguyen, Sara Mm Yasrebi, Marnie Blalock, Sara L Grisales, Craig L Jensen, Marietta M Deguzman

Faculty, Staff and Students Publications

Objective

Systemic lupus erythematosus (SLE) is a complex autoimmune condition with diverse manifestations. Childhood-onset SLE (cSLE) presents more severely than adult-onset disease with a higher incidence of severe neurologic or renal manifestations and lower estimated survival rates. There is limited literature on the range of severe gastrointestinal manifestations at presentation in cSLE, and this lack of information results in underappreciation of these potentially life-threatening complications and little guidance regarding management of these patients.

Methods

We reviewed cases of patients with cSLE and severe GI manifestations at presentation diagnosed at our institution and additionally provide a comprehensive review of existing cases …

Parp Inhibitor Response Is Enhanced In Prostate Cancer When Xrcc1 Expression Is Reduced, Kaveri Goel, Vani Venkatappa, Kimiko L Krieger, Dongquan Chen, Arun Sreekumar, Natalie R Gassman

Faculty, Staff and Students Publications

Prostate cancer (PCa) is the second most common cancer worldwide and the fifth leading cause of cancer-related deaths among men. The emergence of metastatic castration-resistant prostate cancer (mCRPC) after androgen deprivation therapy (ADT) exemplifies the complex disease management for PCa. PARP inhibitors (PARPis) are being tested to treat mCRPC in tumors with defective homologous recombination repair (HRR) to address this complexity. However, increasing resistance towards PARPi in HRR-deficient patients and the low percentage of HRR-defective mCRPC patients requires the identification of new genes whose deficiency can be exploited for PARPi treatment. XRCC1 is a DNA repair protein critical in the …

Aims: The Heart Failure Frailty Score (HFFS) is a novel, multidimensional tool to assess frailty in patients with heart failure (HF). It has been developed to overcome limitations of existing frailty assessment tools while being practical for clinical use. The HFFS reflects the concept of frailty as a multidimensional, dynamic and potentially reversible state, which increases vulnerability to stressors and risk of poor outcomes in patients with HF.

Methods and results: The HFFS was developed through a Delphi consensus process involving 54 international experts. This approach involved iterative rounds of questionnaires and interviews, where a panel of experts provided their …

Graphage: Unleashing The Power Of Graph Neural Network To Decode Epigenetic Aging, Saleh Sakib Ahmed, Nahian Shabab, Abul Hassan Samee, M Sohel Rahman

Faculty, Staff and Students Publications

DNA methylation is a crucial epigenetic marker used in various clocks to predict epigenetic age. However, many existing clocks fail to account for crucial information about CpG sites and their interrelationships, such as co-methylation patterns. We present a novel approach to represent methylation data as a graph, using methylation values and relevant information about CpG sites as nodes, and relationships like co-methylation, same gene, and same chromosome as edges. We then use a graph neural network (GNN) to predict age. Thus our model, GraphAge leverages both the structural and positional information for prediction as well as better interpretation. Although, we …

Faculty, Staff and Students Publications

The ongoing circulation of the Middle East Respiratory Syndrome coronavirus (MERS-CoV) in camels across Asia, the Middle East, and Africa, along with its occasional transmission to humans, demonstrates a need for a MERS vaccine. Previously, we have reported a receptor binding domain (RBD) of MERS-CoV fused with human Fc as a promising vaccine antigen (MERS-CoV RBD-Fc). We generated a stable recombinant CHO cell line expressing such a protein and developed a basic production process suitable for future technological transfer to pilot-scale manufacture. In this study, we employed various in-house analytical assays to examine the characteristics of purified RBD-Fc protein and …

Biomolecular Condensates In Immune Cell Fate, Srikanth Kodali, Caroline M Sands, Lei Guo, Yun Huang, Bruno Di Stefano

Faculty, Staff and Students Publications

Fate decisions during immune cell development require temporally precise changes in gene expression. Evidence suggests that the dynamic modulation of these changes is associated with the formation of diverse, membrane-less nucleoprotein assemblies that are termed biomolecular condensates. These condensates are thought to orchestrate fate-determining transcriptional and post-transcriptional processes by locally and transiently concentrating DNA or RNA molecules alongside their regulatory proteins. Findings have established a link between condensate formation and the gene regulatory networks that ensure the proper development of immune cells. Conversely, condensate dysregulation has been linked to impaired immune cell fates, including ageing and malignant transformation. This Review …

Human noroviruses (HuNoVs) are the leading cause of acute gastroenteritis worldwide in all age groups and cause significant disease and economic burden globally. To date, no approved vaccines or antiviral therapies are available to treat or prevent HuNoV illness. Several candidate vaccines are in clinical trials, although potential barriers to successful development must be overcome. Recently, significant advances have been made in understanding HuNoV biology owing to breakthroughs in virus cultivation using human intestinal tissue-derived organoid (or enteroid) cultures, advances in structural biology technology combined with epitope mapping and increased metagenomic sequencing. New and unexpected strain-specific differences in pandemic versus …

Managing Hypercholesterolemia In Adults Older Than 75 Years Without A History Of Atherosclerotic Cardiovascular Disease: An Expert Clinical Consensus From The National Lipid Association And The American Geriatrics Society, Vera Bittner, Sunny A Linnebur, Dave L Dixon, Daniel E Forman, Ariel R Green, Terry A Jacobson, Ariela R Orkaby, Joseph J Saseen, Salim S Virani

Faculty, Staff and Students Publications

The risk of atherosclerotic cardiovascular disease increases with advancing age. Elevated LDL-cholesterol and non-HDL-cholesterol levels remain predictive of incident atherosclerotic cardiovascular events among individuals older than 75 years. Risk prediction among older individuals is less certain because most current risk calculators lack specificity in those older than 75 years and do not adjust for co-morbidities, functional status, frailty, and cognition which significantly impact prognosis in this age group. Data on the benefits and risks of lowering LDL-cholesterol with statins in older patients without atherosclerotic cardiovascular disease are also limited since most primary prevention trials have included mostly younger patients. Available …

Is Less More? Maximizing Outcomes By Tailoring Treatments To Patients: Oncofertility And Oncomenopause, Janice S Kwon, Marie Plante, Martha Hickey, Annabelle Huguenin, Sarah Hmaidan, Terri Lynn Woodard

Faculty, Staff and Students Publications

Notable advances have been made in improving survival outcomes in various cancers, but some have incurred undesirable costs and effects to patients with respect to fertility and menopause. Patients are living longer with cancer, and patient reported outcomes are influencing decision-making by individuals and their health care providers. It is essential to evaluate existing standards of care on an ongoing basis and prioritize quality of life and long-term survivorship, particularly for interventions in early-stage cancers and risk-reducing strategies that often yield long-term life expectancy.

Introduction: Respiratory syncytial virus (RSV) causes significant morbidity and mortality in young children. For 25 years, palivizumab has been the only effective pharmaceutical RSV preventive.

Areas covered: We summarize the development and a quarter-century of real-world evidence with palivizumab. We highlight its positive impact on the burden of RSV in high-risk children. Based on lessons learnt from its implementation, we suggest strategies for effective and equitable deployment of newer RSV preventives.

Expert opinion: Following failure of the formalin-inactivated RSV vaccine in 1967, RSV intravenous immunoglobulin was approved in 1996 after three decades' research. Subsequently, palivizumab emerged as the most effective …

Dietary Interventions To Support And Improve Sleep Disturbances And Insomnia Disorder In Menopause: From Bench To Bedside, Rosie H Musgrave, Sara Nowakowski, Tamlyn J Watermeyer, Emily J Arentson-Lantz, Greg J Elder

Faculty, Staff and Students Publications

Sleep is essential for maintaining physical and psychological health, and also cognitive health (referred to as 'brain health'). However, the transition to menopause has a direct impact upon sleep. Sleep disturbances are reported by approximately 40%-60% of menopausal women, and insomnia disorder is also prevalent. Diet-based interventions could potentially be used to improve subjective sleep quality in this population, and although there are several promising interventions which have been used in other groups that could be trialled, the evidence base is currently lacking. One particularly promising area for future research is that these interventions might be used alongside, or instead …
