Objective: Physical activity opportunities, such as recess, in educational settings are vital yet only a handful of states have policies in place to ensure daily minimum recess allotment. We aim to investigate associations between physical activity during recess and other time periods to better understand the extent to which recess physical activity is related to physical activity throughout the week. Methods: Children K-5th grade were from four schools in Little Rock, Arkansas. Children wore accelerometers on their waist to assess physical activity across the week. Chi-square and t-tests or Wilcoxon rank-sum tests and multi-level mixed effects generalized linear regression were …

Hippocampal CA1 place cells (PCs) encode both space- and goal-referenced information to support a cognitive map. The mechanism of this referencing and the role of experience remain poorly understood. Here we longitudinally recorded PC activity while head-fixed mice performed a spatial learning task on a treadmill. In a familiar environment, the CA1 representation consisted of PCs that were referenced to either specific spatial locations or a reward goal in approximately equal proportions; however, the CA1 representation became predominately goal-referenced upon exposure to a novel environment, as space-referenced PCs adaptively switched reference frames. Intracellular membrane potential recordings revealed that individual CA1 …

The brain vasculature supplies neurons with glucose and oxygen, but little is known about how vascular plasticity contributes to brain function. Using longitudinal in vivo imaging, we report that a substantial proportion of blood vessels in the adult mouse brain sporadically occlude and regress. Their regression proceeds through sequential stages of blood-flow occlusion, endothelial cell collapse, relocation or loss of pericytes, and retraction of glial endfeet. Regressing vessels are found to be widespread in mouse, monkey and human brains. We further reveal that blood vessel regression cause a reduction of neuronal activity due to a dysfunction in mitochondrial metabolism and …

The best time of the day for chronic exercise training and the mechanism underlying the timing effects is unclear. Here, we show that low-intensity, low-volume treadmill training in mice before sleep yields greater benefits than after waking for muscle contractile performance and systemic glucose tolerance. Baseline muscle performance also exhibits diurnal variations, with higher strength but lower endurance before sleep than after waking. Muscle-specific knockout of circadian clock genes Rev-erbα/β (Rev-MKO) in male mice eradicates the diurnal variations in both training and baseline conditions without affecting muscle mass, mitochondrial content, food intake, or spontaneous activities. Multi-omics and metabolic measurements reveal …

Objectives: Evaluate associations between maternal perceived stress and depressive symptoms, and fetal body composition and organ volumes.
Methods: In the NICHD Fetal 3D Study (2015-2019; n = 2457), stress and depressive symptoms were assessed at enrollment (10-13 weeks). High stress was defined as a Perceived Stress Scale (PSS) score ≥15 and high depressive symptoms, defined as an Edinburgh Postnatal Depression Scale (EPDS) score ≥10. Fetal body composition and organ volumes (cerebellar, lung, liver, and kidney) were measured up to five times between 15 and 40 weeks using three-dimensional (3D) ultrasound technology. Trajectories of body composition and organ volumes across pregnancy …

Emergent Bilingual Educators’ Viewpoint Of Biliteracy Spaces: Building Capacity For Language Preservation And Development, Maria A. Davis
Electronic Theses and Dissertations
This study explored the perspectives of emergent bilingual (EB) educators regarding the value of learning two languages simultaneously for EBs at the elementary level in Texas. The problem examined was that EBs were losing their primary language while acquiring English. More EBs were entering bilingual programs with no language dominance or mixed language dominance, and researchers had explored this issue from various perspectives, including teacher language ideologies and assessment practices based on monolingual standards. This inductive qualitative case study aimed to identify what educators perceived as the benefits of bilingual education in primary classrooms where students learned two languages simultaneously. …

Positive patient experience is associated with improved patient outcomes, but efforts to improve patient experience are often underprioritized, especially with respect to pediatric care. To address this challenge, leaders at several US children's hospitals established the Pediatric Experience Collaborative (PEC) in 2016 to leverage their collaboration and scale to optimize patient, family, and provider experiences. Since then, the PEC has steadfastly incorporated the patient and family perspective in all its endeavors (e.g., installing a family member as one of the organization's co-chairs); has created both structured opportunities and unstructured opportunities for learning and connection; and has embarked on multi-institutional research …

Carbamoyl phosphate synthetase 1 (CPS1) deficiency is a rare metabolic disorder that, in neonatal onset, is typically characterized by severe life-threatening and neurologically injuring hyperammonemic episodes with high unmet patient need. Patients that retain limited enzyme activity may present later in life with less severe hyperammonemia. CPS1 drives the first step in the urea cycle, the pathway terrestrial mammals utilize to metabolize nitrogen. In order to probe the effect of hyperammonemia on the developing nervous system and explore new therapies, a murine Cps1 exon 3-4 mutant was previously generated. However, these mice die within 24 h of birth, limiting study …

Background: When people living with HIV develop pulmonary tuberculosis, it often manifests without detectable acid-fast bacilli on sputum microscopy. We aimed to assess the diagnostic accuracy of stool Xpert MTB/RIF Ultra (hereafter, Ultra) for Mycobacterium tuberculosis detection among adults with HIV.
Methods: This multicentre, prospective diagnostic accuracy study was done in outpatient and inpatient health centres in Eswatini, Mozambique, and Uganda. We enrolled adults aged 15 years and older with HIV with presumptive tuberculosis. We evaluated the diagnostic accuracy of stool Ultra using the simple one-step processing method against a composite microbiological reference standard (CMRS) including three WHO-recommended tuberculosis diagnostic …

Introduction: Strongyloidiasis is an important but underdiagnosed soil-transmitted helminthiasis, particularly in tropical areas and some vulnerable groups.
Objectives: To assess the parasitological prevalence, seroprevalence and sociodemographic factors of Strongyloides stercoralis infection in patients living with human immunodeficiency virus (PLWH) in an endemic area.
Materials and methods: We performed a cross-sectional study of strongyloidiasis in 537 PLWH in two hospitals in Iquitos, Peru, from 20 Oct 2023 to 20 May 2024. We tested patient sera using Strongyloides IgG enzyme-linked immunosorbent assay (ELISA) and stool via the modified Baermann technique and/or charcoal fecal culture as highly sensitive parasitological techniques. We used multivariable …

Cells undergo dramatic morphological changes during embryogenesis, yet how these changes affect the formation of ordered tissues remains elusive. Here, we show that a phase transition leading to the formation of a nematic liquid crystal state during gastrulation in the development of embryos of fish, frogs, and fruit flies occurs by a common mechanism despite substantial differences between these evolutionarily distant animals. Importantly, nematic order forms early before any discernible changes in the shapes of cells. All three species exhibit similar propagation of the nematic phase, reminiscent of nucleation and growth mechanisms. The spatial correlations in the nematic phase in …
Against The Phrase "Aggressive Care", Trevor M Bibler
Against The Phrase "Aggressive Care", Trevor M Bibler
Center for Medical Ethics and Health Policy Staff Publications
Language is the primary technology clinical ethicists use as they offer guidance about norms. Like any other piece of technology, to use the technology well requires attention, intention, skill, and knowledge. Word choice becomes a matter of professional practice. The Brief Report offers clinical ethicists several reasons for rejecting the phrase "aggressive care." Instead, ethicists should consider replacing "aggressive care" with the adjacent concept of a "recovery-focused path." The virtues of this neologism include: the opportunity to set aside the emotion of "aggression," the phrase's accuracy when capturing the intention of the patient or their representative, and an unappreciated rhetorical …

The cardioprotective effects of histone deacetylase (HDAC) inhibitors (HDIs) are at odds with the deleterious effects of HDAC depletion. Here, we use HDAC3 as a prototype HDAC to address this contradiction. We show that adult-onset cardiac-specific depletion of HDAC3 in mice causes cardiac hypertrophy and contractile dysfunction on a high-fat diet (HFD), excluding developmental disruption as a major reason for the contradiction. Genetically abolishing HDAC3 enzymatic activity without affecting its protein level does not cause cardiac dysfunction on HFD. HDAC3 depletion causes robust downregulation of lipid oxidation/bioenergetic genes and upregulation of antioxidant/anti-apoptotic genes. In contrast, HDAC3 enzyme activity abolishment causes …

Objective: Despite β-cell failure in youth with dysglycemia (i.e., impaired glucose tolerance [IGT] and type 2 diabetes), fasting insulin (FI) concentrations are elevated. Herein, we examined the following: 1) metabolic clearance rate of insulin (MCRI) in youth with obesity and normal glucose tolerance (NGT) versus those with IGT versus those with type 2 diabetes; 2) racial and ethnic differences in insulin dynamics; and 3) metabolic/adiposity correlates of MCRI.
Methods: A total of 206 youth underwent assessment of fasting glucose, FI, MCRI and peripheral insulin sensitivity (PIS), first-phase insulin secretion, disposition index, body composition, and abdominal adiposity.
Results: In type 2 …

Anxiety and related disorders are a significant public health burden with rising prevalence in the wake of the COVID-19 pandemic. As demand for effective anxiety treatment increases, so too does the need for strategies to bolster treatment outcomes. Research on the mechanisms of exposure therapy, the frontline behavioral treatment, will be critically important for optimizing clinical outcomes. We outline an initial agenda for future research on the mechanisms of change of exposure therapy, developed in collaboration with a large international team of researchers through the Exposure Therapy Consortium (ETC). Key questions and recommendations for future research focus on five priority …

Background: Epigenetic regulatory genes (epiRG) are pivotal in the epigenetic regulation of the human genome, primarily through DNA and histone modifications. These genes are frequently mutated in human cancers, particularly bladder cancer (BC). However, the functional impact of epiRG mutations on patient outcomes remains poorly understood.
Methods: In this study, we developed gene signatures for the most frequent genomic aberrations of epiRG using The Cancer Genome Atlas Bladder Carcinoma (TCGA-BLCA) dataset and validated these signatures with independent tumor expression profiles for prognostic relevance.

Clinical and translational science needs to address roadblocks to the translational processes. We conducted a survey at two institutions, a private medical school and a large public university, to understand the frequency and distribution of barriers and roadblocks to research. We reviewed the literature to compile a pool of barriers and roadblocks and convened a panel of relevant stakeholders to develop a 20-item questionnaire. Survey respondents were asked to select and prioritize the five leading clinical and translational roadblocks, provide information regarding their academic degrees and rank/position, complete open-ended items regarding their areas of research, and optionally add additional remarks …

The SLFN14 endoribonuclease is a post-transcriptional regulator that targets the ribosome and its associated RNA substrates for codon-bias translational repression. SLFN14 nuclease activity is linked to antiviral defense and platelet function. Despite its prominent role in gene regulation, the molecular signals regulating SLFN14 substrate recognition and catalytic activation remain unclear. SLFN14 dysregulation is linked to human diseases, including ribosomopathies and inherited thrombocytopenia, thus underscoring the importance of establishing the signals coordinating its RNA processing activity. Here, we reconstitute active full-length human SLFN14 and report a high-resolution cryoEM reconstruction of the SLFN14•RNA complex. The structure reveals a medallion-like architecture that shares …

Introduction: Despite their high prevalence and impact, depression and anxiety are not routinely screened for, and accuracy of screening procedures is unknown in adult-onset dystonia. We evaluated accuracy parameters of selected self-rated scales for depression and anxiety in patients with idiopathic cervical dystonia (CD).
Methods: Two-hundred-and-ten patients with idiopathic CD were recruited from 10 movement disorders centers from the US, Canada, Australia, and UK. At the end of each botulinum toxin cycle, participants were administered the Adult Standard Mini-International Neuropsychiatric Interview (MINI) as reference standard for depression and anxiety. Participants completed 8 self-administered index instruments (2 for depression, 2 for …

Lysosomes are cytoplasmic organelles central for the degradation of macromolecules to maintain cellular homoeostasis and health. However, how lysosomal activity can be boosted to counteract ageing and ageing-related diseases remains elusive. Here we reveal that silencing specific vacuolar H+-ATPase subunits (for example, vha-6), which are essential for intestinal lumen acidification in Caenorhabditis elegans, extends lifespan by ~60%. This longevity phenotype can be explained by an adaptive transcriptional response typified by induction of a set of transcripts involved in lysosomal function and proteolysis, which we termed the lysosomal surveillance response (LySR). LySR activation is characterized by boosted lysosomal activity …

Measles is a potentially deadly viral infection spread via respiratory droplets from infected individuals. Outbreaks occur when vaccine coverage drops below the threshold of herd, or community, immunity. Using a sequencing-based approach, we report the prospective (January 7, 2025) detection of measles in nucleic acid extracts from 2 wastewater treatment plants in Houston, Texas, with a population of more than 218 000 residents. The sequencing data from 2 samples contained 53 unique reads mapping to 11 different regions of the measles virus genome with a 99.4% match to genotype B3. Importantly, no detections were observed from 821 previous samples from …
