Effect of BMI and symptoms at celiac disease diagnosis on serology normalization after 2 years of a gluten-free diet in children.

Objectives: To determine if after 2 years of consuming a gluten-free diet post celiac disease diagnosis, pediatric patients who were overweight or obese at diagnosis are less likely to normalize celiac disease serologies as compared with those who were normal weight or underweight at diagnosis. Secondary aims include characterizing how initial symptoms at presentation predict body mass index (BMI) change and serology improvement over the first 2 years of being on a gluten-free diet following diagnosis of celiac disease.

Methods: A retrospective chart review was performed that included all biopsy-proven celiac disease patients followed at Stony Brook Children's Hospital's Celiac Disease Center diagnosed between the years 2007-2022.

Coronary artery calcium on lung cancer radiation planning CT aids cardiovascular risk assessment.

Background: Patients with non-small cell lung cancer (NSCLC) undergoing thoracic radiation are at high cardiovascular risk. Semiquantitative assessment of coronary artery calcification (CAC) on baseline planning non-gated chest computed tomography (CT) scans may help further risk stratify patients.

Objectives: This study aimed to characterize the association between CAC and major adverse cardiovascular events (MACE; myocardial infarction or stroke) and assess the utility of semiquantitative assessment of CAC.

Evaluating Safety and Durability of Adolescent Metabolic and Bariatric Surgery.

Introduction: Metabolic bariatric surgery (MBS) has demonstrated safety in its usage in the adolescent population and can aid in curbing the rising obesity epidemic. However, long-term data surrounding durability of MBS in this population is limited. This study aims to examine both short and long-term outcomes of MBS in adolescents, as well as identify patient characteristics and demographics that may impact operative safety and durability.

Targeted single cell expression profiling identifies integrators of sleep and metabolic state.

Animals modulate sleep in accordance with their internal and external environments. Metabolic cues are particularly potent regulators of sleep, allowing animals to alter their sleep timing and amount depending on food availability and foraging duration. The fruit fly, , suppresses sleep in response to acute food deprivation, presumably to forage for food.

Transitions of care for adolescents with disorders of gut-brain interaction.

Objectives: Little is known about the experience of adolescents and young adults (AYA) with disorders of gut-brain interaction (DGBI) who transition from pediatric to adult gastroenterology care. In this two-part study, we used quantitative and qualitative methods to: (1) assess incidence of optimal versus suboptimal transitions of care for AYA with DGBI, (2) characterize health and quality of life effects of the transition, and (3) identify barriers and facilitators for optimal transition of care.

Methods: In Part 1, we conducted a retrospective review of AYA referrals to our adult neurogastroenterology clinic who had transitioned from pediatric gastroenterology care (N = 109, 17-23 years, 72% female).

Decoding Endothelial MPL and JAK2V617F Mutation: Insight Into Cardiovascular Dysfunction in Myeloproliferative Neoplasms.

Background: Patients with JAK2V617F-positive myeloproliferative neoplasms (MPNs) and clonal hematopoiesis of indeterminate potential face a significantly elevated risk of cardiovascular diseases. Endothelial cells carrying the JAK2V617F mutation have been detected in many patients with MPN. In this study, we investigated the molecular basis for the high incidence of cardiovascular complications in patients with MPN.

Universal and Versatile Magnetic Connectors for Microfluidic Devices.

World-to-chip interfacing remains a critical issue for microfluidic devices. Current solutions to connect tubing to rigid microfluidic chips remain expensive, laborious, or require specialized skills and precision machining. Here, we report reusable, inexpensive, and easy-to-use connectors that enable monitoring of the connection ports.

Association Between Atopic Dermatitis and Impaired Mobility among Adults in the United States: Findings from the 2001-2006 National Health and Nutrition Examination Survey.

Objective: Atopic dermatitis (AD) is an inflammatory skin condition affecting both mental and physical health. Although research has shown reduced physical activity levels among patients with AD, there is a scarcity of studies examining baseline mobility, which refers to the standard level of functional ambulation or movement capability. We analyzed the relationship between AD and baseline mobility among U.

The Role of Retrotransposons and Endogenous Retroviruses in Age-Dependent Neurodegenerative Disorders.

Over 40% of the human genome is composed of retrotransposons, DNA species that hold the potential to replicate via an RNA intermediate and are evolutionarily related to retroviruses. Retrotransposons are most studied for their ability to jump within a genome, which can cause DNA damage and novel insertional mutations. Retrotransposon-encoded products, including viral-like proteins, double-stranded RNAs, and extrachromosomal circular DNAs, can also be potent activators of the innate immune system.

Magnetically functionalized hydrogels for high-throughput genomic applications.

Single-cell genomics has revolutionized tissue analysis by revealing the genetic program of individual cells. The key aspect of the technology is the use of barcoded beads to unambiguously tag sequences originating from a single cell. The generation of unique barcodes on beads is mainly achieved by split-pooling methods, which are labor-intensive due to repeated washing steps.

Tarsal Tunnel Syndrome Associated With a Bipartite Talus.

Background: Talus bipartitus is a rare skeletal anomaly that may be mistaken for an os trigonum, a relatively common accessory ossicle found posterior to the talus. Both are believed to be formed similarly with the failed fusion of the talus with a second ossification center. Os trigonum is often diagnosed incidentally or found on radiographs obtained in symptomatic patients with signs of os trigonum syndrome, which presents with posterolateral ankle pain.

Deciphering the differential impact of thrombopoietin/MPL signaling on hematopoietic stem/progenitor cell function in bone marrow and spleen.

Thrombopoietin (TPO) and its receptor MPL play crucial roles in hematopoietic stem cell (HSC) function and platelet production. However, the precise effects of TPO/MPL signaling on HSC regulation in different hematopoietic niches remain unclear. Here, we investigated the effects of TPO/MPL ablation on marrow and splenic hematopoiesis in TPO and MPL mice during aging.

The role of preoperative aspartate aminotransferase-to-platelet ratio index in predicting complications following total hip arthroplasty.

Background: The purpose of this study was to investigate the relationship between preoperative aspartate aminotransferase-to-platelet ratio index (APRI) and postoperative complications following total hip arthroplasty (THA).

Methods: All THA for osteoarthritis patients from 2007 to 2020 within the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database were included in this study. Subjects were subsequently divided into cohorts based on APRI.

Robust and rapid partitioning in thermoplastic.

Partitioning is the core technology supporting digital assays. It divides a sample into thousands of individual reactors prior to amplification and absolute quantification of target molecules. Thermoplastics are attractive materials for large scale manufacturing, however they have been seldomly used for fabricating partitioning arrays.

Preoperative medically supervised weight loss programs and weight loss outcomes following bariatric surgery - a prospective analysis.

Background: Prior to undergoing bariatric surgery, many insurance companies require patients to attend medically supervised weight management visits for 3-6 months to be eligible for surgery. There have been few studies that have looked specifically at the relationship between medically supervised weight management visit attendance and postoperative outcomes, and the current literature reports discrepant findings.

Objectives: This project aimed to better characterize the relationship between preoperative medically supervised weight management visit attendance and postoperative weight loss outcomes by examining weight loss up to 5 years postbariatric surgery, and by stratifying findings according to the type of surgery undergone.

Initial interactions with the FDA on developing a validation dataset as a medical device development tool.

Quantifying tumor-infiltrating lymphocytes (TILs) in breast cancer tumors is a challenging task for pathologists. With the advent of whole slide imaging that digitizes glass slides, it is possible to apply computational models to quantify TILs for pathologists. Development of computational models requires significant time, expertise, consensus, and investment.

Single-Cell Spatial MIST for Versatile, Scalable Detection of Protein Markers.

High-multiplex detection of protein biomarkers across tissue regions has been an attractive spatial biology approach due to significant advantages over traditional immunohistochemistry (IHC) methods. Different from most methods, spatial multiplex in situ tagging (MIST) transfers the spatial protein expression information to an ultrahigh-density, large-scale MIST array. This technique has been optimized to reach single-cell resolution by adoption of smaller array units and 30% 8-arm PEG polymer as transfer medium.

TDP-43 pathology in Drosophila induces glial-cell type specific toxicity that can be ameliorated by knock-down of SF2/SRSF1.

Accumulation of cytoplasmic inclusions of TAR-DNA binding protein 43 (TDP-43) is seen in both neurons and glia in a range of neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) and Alzheimer's disease (AD). Disease progression involves non-cell autonomous interactions among multiple cell types, including neurons, microglia and astrocytes. We investigated the effects in Drosophila of inducible, glial cell type-specific TDP-43 overexpression, a model that causes TDP-43 protein pathology including loss of nuclear TDP-43 and accumulation of cytoplasmic inclusions.
