Antenatal Steroids Enhance Long-Term Neonatal Lung Outcomes and are Associated with Placental Alterations in Experimental Chorioamnionitis.

Intrauterine inflammation from chorioamnionitis (CA) is associated with placental dysfunction and increased risk of bronchopulmonary dysplasia (BPD), the chronic lung disease of prematurity. Antenatal steroid (ANS) treatment improves early respiratory outcomes for premature infants. However, it remains unclear whether ANS improve long-term respiratory outcomes, and whether these effects are mediated through improvement of placental dysfunction and/or direct impact on the fetal lung.

Induction on Insulin Resistance In Vitro.

Cellular model serves as a crucial preclinical research tool, providing essential insights into the mechanistic aspects of disease biology. Particularly in the study of chronic metabolic disorders such as type 2 diabetes mellitus and obesity, palmitate (a saturated fatty acid) is often used as a key inducer of insulin resistance in vitro. Within this chapter, I delineate procedures aimed at inducing insulin resistance in AC16 human cardiac-derived cells.

Thyroid hormone and the Liver.

It is known that thyroid hormone can regulate hepatic metabolic pathways including cholesterol, de novo lipogenesis, fatty acid oxidation, lipophagy, and carbohydrate metabolism. Thyroid hormone action is mediated by the thyroid hormone receptor (THR) isoforms and their coregulators, and THRβ is the main isoform expressed in the liver. Dysregulation of thyroid hormone levels, as seen in hypothyroidism, has been associated with dyslipidemia and metabolic dysfunction-associated fatty liver disease.

Pediatrics leading the way: co-enrollment as the next step in health-related social needs screening and referral.

Purpose Of Review: To contextualize how pediatrics led the field in developing and implementing tools to screen for social determinants of health in clinical care as well as in creating innovative interventions to mitigate them, and to summarize where the evidence points as the next frontier.

Recent Findings: The evidence showed that health-related social needs (HRSN), like food insecurity, energy insecurity, and housing instability, continue to drive poor health outcomes across the lifespan; patients and healthcare providers are open to discussing HRSN in clinical settings, though some providers feel ill-equipped to do so; to mitigate HRSN, healthcare plays a unique role in ensuring patients' HRSN are understood, referring to effective resources through building strong, lasting relationships with community partners, embedding services in the healthcare setting across all departments, and empowering patient families to participate in programs and services; and administrative burden hinders families from getting all the benefits to which they are entitled, which streamlined co-enrollment processes can address.

Summary: Pediatric providers can add a unique and credible voice to seeking changes to the safety-net, including co-enrollment, that could reduce administrative burden, address patients' HRSN, and improve health starting in the prenatal period through later adulthood.

Defining the transition from new to normal: a qualitative investigation of the clinical change process.

Background: Understanding how and when a new evidence-based clinical intervention becomes standard practice is crucial to ensure that healthcare is delivered in alignment with the most up-to-date knowledge. However, rigorous methods are needed to determine when a new clinical practice becomes normalized to the standard of care. To address this gap, this study qualitatively explores how, when, and why a clinical practice change becomes normalized within healthcare organizations.

Surgical Trends in Use of Lumbar Disk Arthroplasty Versus Lumbar Fusion From 2010 to 2021.

Introduction: Lumbar disk arthroplasty (LDA) is a relatively novel procedure with limited indications and use in the United States, especially relative to lumbar fusion (LF). This study aimed to determine surgical trends between LDA versus LF over the past 10 years to quantify absolute/relative surgical volume over time and compare baseline patient demographics, readmission, 2-year revision rates, and costs-of-care.

Methods: A total of 714,268 patients were identified from a nationwide database who underwent LF (n = 710,527) or LDA (n = 3,741) from 2010 to 2021.

Disruption of epithelial barrier integrity via altered GILZ/c-Rel/RACK1 signaling in inflammatory bowel disease (IBD).

Background And Aim: Given the role of Receptor for Activated C Kinase 1 (RACK1) in both immune cell activation and in the maintenance of the intestinal epithelial barrier integrity, we investigated whether it was involved in inflammatory bowel disease (IBD).

Methods: RACK1 expression was analyzed in intestinal mucosal samples of healthy and IBD patients, in mice with chemically-induced colitis and in diseased in vitro 2D and 3D co-culture models by luciferase assay, RT-qPCR, Western blotting, immunofluorescence and immunohistochemistry. Based on our finding that glucocorticoid-induced leucine zipper (GILZ or tsc22d3) positively correlates with RACK1 expression in IBD patients, GILZ knock-out mice and cell silencing experiments were performed.

Curation and validation of electronic medical record-based dementia diagnoses in the VA Million Veteran Program.

Background: The age distribution and diversity of the VA Million Veteran Program (MVP) cohort make it a valuable resource for studying the genetics of Alzheimer's disease (AD) and related dementias (ADRD).

Objective: We present and evaluate the performance of several International Classification of Diseases (ICD) code-based classification algorithms for AD, ADRD, and dementia for use in MVP genetic studies and other studies using VA electronic medical record (EMR) data. These were benchmarked relative to existing ICD algorithms and AD-medication-identified cases.

Protecting historically marginalized groups or targeted marketing? A computational analysis of individuals engaging with public and protected cigar-branded tweets.

Introduction: Swisher Sweets, a leading brand of little cigars and cigarillos in the United States, switched its Twitter account to protected status, limiting access to its tweets. This study examines how the protected status of Swisher Sweets tweets influences post engagement, aiming to inform regulatory strategies for branded tobacco promotions on social media.

Method: Using natural language processing, we predicted the demographics of individuals replying to Swisher Sweets' public and protected tweets.

Elucidating the Mechanism of Recognition and Binding of Heparin to Amyloid Fibrils of Serum Amyloid A.

Amyloid diseases feature pathologic deposition of normally soluble proteins and peptides as insoluble fibrils in vital organs. Amyloid fibrils co-deposit with various nonfibrillar components including heparan sulfate (HS), a glycosaminoglycan that promotes amyloid formation in vitro for many unrelated proteins. HS-amyloid interactions have been proposed as a therapeutic target for inflammation-linked amyloidosis wherein N-terminal fragments of serum amyloid A (SAA) protein deposit in the kidney and liver.

Deep learning algorithm enables automated Cobb angle measurements with high accuracy.

Objective: To determine the accuracy of automatic Cobb angle measurements by deep learning (DL) on full spine radiographs.

Materials And Methods: Full spine radiographs of patients aged > 2 years were screened using the radiology reports to identify radiographs for performing Cobb angle measurements. Two senior musculoskeletal radiologists and one senior orthopedic surgeon independently annotated Cobb angles exceeding 7° indicating the angle location as either proximal thoracic (apices between T3 and T5), main thoracic (apices between T6 and T11), or thoraco-lumbar (apices between T12 and L4).

Safety and preliminary efficacy of transcutaneous auricular vagus nerve stimulation on chronic knee pain: A pilot trial.

Objective: Transcutaneous auricular vagus nerve stimulation () may be an innovative treatment for symptoms of knee osteoarthritis (OA) due to possible shared pathological mechanisms between diminished parasympathetic function, central pain mechanisms, and knee pain. Thus, we sought to test the safety and preliminary efficacy of tVNS in people with knee OA.

Design: A pilot trial in which participants received a 60-min tVNS was conducted.

Global amyloid burden enhances network efficiency of tau propagation in the brain.

Background: Amyloid-β (Aβ) and hyperphosphorylated tau are crucial biomarkers in Alzheimer's disease (AD) pathogenesis, interacting synergistically to accelerate disease progression. While Aβ initiates cascades leading to tau hyperphosphorylation and neurofibrillary tangles, PET imaging studies suggest a sequential progression from amyloidosis to tauopathy, closely linked with neurocognitive symptoms.

Objective: To analyze the complex interactions between Aβ and tau in AD using probabilistic graphical models, assessing how regional tau accumulation is influenced by Aβ burden.
