Conformal Metamaterials with Active Tunability and Self-Adaptivity for Magnetic Resonance Imaging.

Metamaterials hold great potential to enhance the imaging performance of magnetic resonance imaging (MRI) as auxiliary devices, due to their unique ability to confine and enhance electromagnetic fields. Despite their promise, the current implementation of metamaterials faces obstacles for practical clinical adoption due to several notable limitations, including their bulky and rigid structures, deviations from optimal resonance frequency, and inevitable interference with the radiofrequency (RF) transmission field in MRI. Herein, we address these restrictions by introducing a flexible and smart metamaterial that enhances sensitivity by conforming to patient anatomies while ensuring comfort during MRI procedures.

Access to Pediatric Bed Capacity According to Social Determinants of Health: All Beds Are Not Created Equal.

Objective: To study pediatric inpatient hospital capacity and resources, characterizing differences according to social determinants of health (SDoH) using market share techniques.

Study Design: This cross-sectional study uses non-elective inpatient discharges (≥1 month to ≤19 years) from Healthcare Cost and Utilization Project and American Hospital Association surveys to derive hospital capacity and resources/capability. We include US hospitals with ≥1 pediatric bed and ≥1 pediatric discharge and calculate per bed capital, expenditure, and staffing, transfer rates, payer-mix, and adjusted central line-associated blood stream infection (CLABSI) rate.

Associations between health-related social needs and postpartum linkage to care.

Introduction: Ongoing care after pregnancy is recommended. Health-related social needs (HRSNs) are recognized barriers to care, yet their pregnancy-related prevalence and associations with care are unknown. Researchers sought to assess (1) the prevalence of HRSNs during pregnancy-based care, and (2) their associations with ongoing care after pregnancy.

Objectives: Auditory brainstem response (ABR) is the gold standard to assess hearing loss in pediatric patients. Multiple widely accepted ABR protocols with varying parameters are accepted, difference in standards may lead to misdiagnosis or delay in diagnosis and treatment. This study investigates the quality of ABR testing in pediatric patients in addition to changes in diagnoses and management.

Advocating for an Advanced Cardiac POCUS Curriculum Among Internal Medicine Residents.

Advocating for integrating a cardiac point-of-care ultrasound (POCUS) curriculum into Internal Medicine residency, this letter emphasizes the unique advantages of cardiac POCUS, particularly its rapid utility and safety, while highlighting existing knowledge gaps among trainees. This perspective research letter underscores the need for a structured advanced cardiac POCUS elective to address the knowledge and skill gaps among internal medicine trainees who have taken the introductory POCUS elective, providing a career preparatory course for internal medicine residents interested in cardiology, critical care, hospital medicine, primary care, and rural medicine. The perspective research paper also underscores the feasibility and benefits of such training, ultimately supporting the implementation of an advanced cardiac POCUS elective in the United States Internal Medicine residency programs.

Initial outcomes in a sickle cell disease transition clinic.

Background: Transition in sickle cell disease (SCD) is associated with an alarming increase in acute care utilization, cost, and risk of early mortality. Effective transition preparation is crucial to address these issues. We established a multidisciplinary transition clinic at our urban SCD center in the fall of 2021.

Female Representation in Integrated Interventional Radiology Residency: Trends, Underrepresentation, and Modest Growth Over Five Years.

Objective: Women remain a minority of trainees in interventional radiology (IR) since the residency's inception in 2014. Similar phenomena have been observed in other surgical specialties. Our study aims to quantify changes in female trainee representation in integrated IR over a five-year period from the 2018-19 to 2022-23 academic years and to compare with trends in other specialties.

Integrated NMR-crystallography-computational approach for molecular recognition studies of human Gαi3 protein by a small molecule inhibitor.

The small molecule IGGi-11 targets Gαi subunits of heterotrimeric guanine nucleotide-binding proteins. Gα subunits are activated by G-protein-coupled receptors in response to extracellular stimuli by accelerating the exchange of GDP for GTP, but they are also activated by intracellular proteins like GIV, of which elevated levels correlate with increased cell migration and cancer metastasis. IGGi-11 disrupts the interaction of Gαi proteins with GIV and inhibits pro-invasive traits of metastatic breast cancer cells without interfering with GPCR signaling.

Associations of early life per- and polyfluoroalkyl substances (PFAS) exposure with body mass index and risk of overweight or obesity at age 2-18 years: Mixture analysis in the prospective Boston Birth Cohort.

Background: Per- and polyfluoroalkyl substances (PFAS) are a class of widespread persistent chemicals, which may have obesogenic effects during the fetal period. This study investigated the long-term association of maternal plasma PFAS concentrations at delivery and their mixture with child body mass index (BMI) and the risk of Overweight or Obesity (OWO) at the age of 2-18 years.

Methods: The study included 1189 mother-child dyads from the prospective Boston Birth Cohort.

Royal Canadian Mounted Police cadets' exposure to potentially psychologically traumatic events during the Cadet Training Program.

Lifetime exposures to potentially psychologically traumatic events (PPTEs) among Royal Canadian Mounted Police (RCMP) cadets starting the Cadet Training Program (CTP) appear lower than exposures reported by serving RCMP, but the prevalence of PPTE exposures during the CTP remains unknown. The current study assessed PPTE exposures during the CTP and examined associations with mental disorders among RCMP cadets. Participants were cadets (n = 449, 24.

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.

Increasing diversity in the nutrition, obesity, and diabetes biomedical workforce: the BRIDGES consortium.

Scientists from diverse backgrounds are underrepresented (UR) in academia. This lack of diversity impedes scientific discovery and innovation. UR scientists tend to conduct research on issues relevant to UR populations, including chronic disease prevention and management, and health disparities.

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.
