Intersections of Structural State-Level Racism and Neighborhood Deprivation on Nutrition and Obesity for Black Adolescents.

Purpose: Black adolescents in the United States face disproportionate poor nutrition and obesity risk due to racism. Intersections of larger structural contexts that pose differential access to Black adolescents' health resources, such as state-level racism and neighborhood-level disadvantage, may govern these risks. The purpose of this correlational study was to examine the associations between state-level racism, neighborhood disadvantage, and their intersection with nutrition and obesity for Black adolescents in a longitudinal study.

Circadian Disruption in Glaucoma: Causes, Consequences, and Countermeasures.

This review explores the intricate relationship between glaucoma and circadian rhythm disturbances. As a principal organ for photic signal reception and transduction, the eye plays a pivotal role in coordinating the body's circadian rhythms through specialized retinal ganglion cells (RGCs), particularly intrinsically photosensitive RGCs (ipRGCs). These cells are critical in transmitting light signals to the suprachiasmatic nucleus (SCN), the central circadian clock that synchronizes physiological processes to the 24-hour light-dark cycle.

Effectiveness of a Breast Cancer Educational Conference Targeting Healthcare Workers in Honduras.

Previous studies have demonstrated that many healthcare workers in low- and middle-income countries (LMICs) lack the appropriate training and knowledge to recognize and diagnose breast cancer at an early stage. As a result, women in LMICs are frequently diagnosed with late-stage breast cancer (Stage III/IV) with a poor prognosis. We hosted a 1-day breast cancer educational conference directed towards healthcare workers in Honduras.

Diversity-Related, Student-Led National Medical Organizations: Leadership Opportunities for Learners.

Introduction: In light of the lack of diversity in academic medicine leadership, diversity-related, student-led national medical organizations (NMOs) provide a space for solace and reprieve among common peers while providing an opportunity to develop leadership competencies in a supportive environment. Despite the impact NMOs have had on cultivating generations of leaders in medicine, trainees may not identify opportunities for leadership development that are transferable to future careers in academic medicine.

Methods: We designed and implemented a dynamic 60-minute workshop with an interactive PowerPoint presentation, author-owned video testimonials (from past student leaders of NMOs), two case presentations, and reflection exercises.

Cognitive abilities are associated with rapid dynamics of electrophysiological connectome states.

Time-varying changes in whole-brain connectivity patterns, or connectome state dynamics, hold significant implications for cognition. However, connectome dynamics at fast (>1 Hz) timescales highly relevant to cognition are poorly understood due to the dominance of inherently slow fMRI in connectome studies. Here, we investigated the behavioral significance of rapid electrophysiological connectome dynamics using source-localized EEG connectomes during resting state ( = 926, 473 females).

Rapid dynamics of electrophysiological connectome states are heritable.

Time-varying changes in whole-brain connectivity patterns, or connectome state dynamics, are a prominent feature of brain activity with broad functional implications. While infraslow (<0.1 Hz) connectome dynamics have been extensively studied with fMRI, rapid dynamics highly relevant for cognition are poorly understood.

CRISPR/Cas9-Based Protocol for Precise Genome Editing in Induced Pluripotent Stem Cells.

The advent of clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9-based genome editing has marked a significant advancement in genetic engineering technology. However, the editing of induced pluripotent stem cells (iPSCs) with CRISPR presents notable challenges in ensuring cell survival and achieving high editing efficiency. These challenges become even more complex when considering the specific target site.

Characterization of gallbladder disease in metachromatic leukodystrophy across the lifespan.

Metachromatic leukodystrophy (MLD) is a progressive demyelinating disorder resulting from the toxic accumulation of sulfatides. The stereotyped neurodegeneration of MLD is well understood, and cases are categorized into subtypes by age at neurologic onset: late infantile (LI), juvenile (J), and adult. The systemic burden of disease, such as gallbladder involvement, however, is less well characterized.

- a large-scale dataset of 3D medical shapes for computer vision.

Methods: We searched MEDLINE, Embase, and Cochrane Central in October 2023 to identify RCTs comparing Hartmann's resection (HR), primary resection and anastomosis (PRA), or laparoscopic peritoneal lavage (LPL) among patients with class Ib-IV Hinchey diverticulitis. Outcomes of interest were prioritized by an international, multidisciplinary panel including two patient partners.

New strategies to advance plant transformation.

Plants are an important source of food, energy, and bioproducts. Advances in genetics, genomics-assisted breeding, and biotechnology have facilitated the combining of desirable traits into elite cultivars. To ensure sustainable crop production in the face of climate challenges and population growth, it is essential to develop and implement techniques that increase crop yield and resilience in environments facing water scarcity, nutrient deficiencies, and other abiotic and biotic stressors.

Challenges and opportunities of acquiring cortical recordings for chronic adaptive deep brain stimulation.

Deep brain stimulation (DBS), a proven treatment for movement disorders, also holds promise for the treatment of psychiatric and cognitive conditions. However, for DBS to be clinically effective, it may require DBS technology that can alter or trigger stimulation in response to changes in biomarkers sensed from the patient's brain. A growing body of evidence suggests that such adaptive DBS is feasible, it might achieve clinical effects that are not possible with standard continuous DBS and that some of the best biomarkers are signals from the cerebral cortex.

SPRTN metalloprotease participates in repair of ROS-mediated DNA-protein crosslinks.

Exposure to reactive oxygen species (ROS) can induce DNA-protein crosslinks (DPCs), unusually bulky DNA lesions that block replication and transcription and play a role in aging, cancer, cardiovascular disease, and neurodegenerative disorders. Repair of DPCs depends on the coordinated efforts of proteases and DNA repair enzymes to cleave the protein component of the lesion to smaller DNA-peptide crosslinks which can be processed by tyrosyl-DNA phosphodiesterases 1 and 2, nucleotide excision and homologous recombination repair pathways. DNA-dependent metalloprotease SPRTN plays a role in DPC repair, and SPRTN-deficient mice exhibit an accelerated aging phenotype and develop liver cancer early in life.

Carbapenem-induced β-lactamase-isoform expression trends in Acinetobacter baumannii.

Carbapenem-resistant Acinetobacter baumannii (CRAb) is an urgent bacterial threat to public health, with only a few treatment options and a > 50% fatality rate. Although several resistance mechanisms are understood, it is still impossible to predict which mutations are most likely to occur. Here, we demonstrate that independent samples of Ab, exposed to different carbapenems with escalating concentrations, show concentration- and carbapenem-dependent trends in β-lactamase-isoform expression.

Cyclic quantum annealing: searching for deep low-energy states in 5000-qubit spin glass.

Quantum computers promise a qualitative speedup in solving a broad spectrum of practical optimization problems. The latter can be mapped onto the task of finding low-energy states of spin glasses, which is known to be exceedingly difficult. Using D-Wave's 5000-qubit quantum processor, we demonstrate that a recently proposed iterative cyclic quantum annealing algorithm can find deep low-energy states in record time.

The histone H3.3 K27M mutation suppresses Ser31phosphorylation and mitotic fidelity, which can directly drive gliomagenesis.

Serine 31 is a phospho-site unique to the histone H3.3 variant; mitotic phospho-Ser31 is restricted to pericentromeric heterochromatin, and disruption of phospho-Ser31 results in chromosome segregation defects and loss of p53-dependant G cell-cycle arrest. Ser31 is proximal to the H3.

QSP Modeling Shows Pathological Synergism Between Insulin Resistance and Amyloid-Beta Exposure in Upregulating VCAM1 Expression at the BBB Endothelium.

Type 2 diabetes mellitus (T2DM), characterized by insulin resistance, is closely associated with Alzheimer's disease (AD). Cerebrovascular dysfunction is manifested in both T2DM and AD, and is often considered as a pathological link between the two diseases. Insulin signaling regulates critical functions of the blood-brain barrier (BBB), and endothelial insulin resistance could lead to BBB dysfunction, aggravating AD pathology.

Factors and outcomes associated with under- and overdiagnosis of sepsis in the first hour of emergency department care.

Background: Sepsis remains the leading cause of in-hospital death and one of the costliest inpatient conditions in the United States, while treatment delays worsen outcomes. We sought to determine factors and outcomes associated with a missed emergency physician (EP) diagnosis of sepsis.

Methods: We conducted a secondary analysis of a prospective single-center observational cohort of undifferentiated, critically ill medical patients (September 2020-May 2022).

Nitrogen Deposition Weakens Soil Carbon Control of Nitrogen Dynamics Across the Contiguous United States.

Anthropogenic nitrogen (N) deposition is unequally distributed across space and time, with inputs to terrestrial ecosystems impacted by industry regulations and variations in human activity. Soil carbon (C) content normally controls the fraction of mineralized N that is nitrified (ƒ), affecting N bioavailability for plants and microbes. However, it is unknown whether N deposition has modified the relationships among soil C, net N mineralization, and net nitrification.
