Mobile phone interventions are evidence-based methods for preventing obesity among Latino adults and school-aged children; however, few such interventions exist to improve the obesogenic behaviors of children in the developmentally critical preschool years (ages 2-5). Focusing on this age group is important since over one-quarter of 2- to 5-year-old Latino children are overweight or obese. Moreover, most documented interventions target mothers exclusively, ignoring the influence that other caregivers such as fathers and grandparents have on the environment and the child's behaviors.

Using a social network approach, we characterize who Mexican-origin young adults perceive as social support sources for oral health behaviors and provide additional validity evidence for Oral Health Behavior Social Support Scales (OHBSS). From April to September 2022, we gathered social network data from 62 Mexican-origin adults (21-40 years old) through Zoom interviews about their perceived received social support for three oral health behaviors (toothbrushing, flossing, and obtaining dental care) from three potential sources of support (family, health providers, and others/friends). Overall, we found similar results across all three oral health behaviors.

  • Healthy food nudges may be particularly beneficial for individuals from lower socioeconomic backgrounds, prompting a study on their effectiveness in grocery stores across different demographics.
  • Researchers analyzed data from multiple trials, focusing on how characteristics like education, gender, and age impact the success of these nudges in increasing the purchase of fruits and vegetables.
  • Findings revealed that, overall, healthy food nudges did not significantly influence fruit and vegetable purchases among participants, regardless of their sociodemographic profiles, suggesting the need for more effective strategies.

The United States faces a shortage of primary care physicians. To address this, there have been pioneering efforts to develop accelerated pathways with a primary care focused curriculum for undergraduate medical education. The New York University Grossman Long Island School of Medicine (NYU GLISOM) was conceptualized as the first standalone, accelerated, tuition-free program in the US in over 100 years, with mission-centered curriculum on primary care and health system leadership.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.

This study explored the feasibility and acceptability of Entre Herman@s, a novel sibling-based intervention designed to engage siblings to increase PrEP utilization among Latino men who have sex with men (LMSM). Siblings were trained in rudimentary motivational interviewing skills to uncover, evoke, and strengthen their brother's motivation to use PrEP, using the constructs of the Information-Motivation-Behavioral Skills (IMB) model for health behavior change. This pilot demonstrated high feasibility, meeting recruitment, retention, and intervention completion targets.

  • Renal cell carcinoma (RCC) is linked to lifestyle factors like smoking, obesity, and hypertension, but about 3% of cases are hereditary, with seven major syndromes identified by NCCN that heighten RCC risk.* -
  • Inherited mutations in DNA repair genes, especially ATM, BRCA, and TP53, raise the risk for various cancers, and germline pathogenic mutations in ATM are surprisingly connected to RCC despite limited historical recognition.* -
  • A case study of a 68-year-old woman with a germline pathogenic ATM mutation who developed high-risk clear cell RCC highlights the need for better screening and research on targeted treatments in patients with hereditary cancer syndromes.*

The need for culturally tailored pain care is well-recognized, yet few studies report how existing interventions can be adapted to the needs of culturally and linguistically diverse populations. This report describes a formative mixed-methods approach using intervention mapping-adapt and the expanded framework for reporting adaptations and modifications to evidence-based interventions to adapt and report modifications of an existing physical therapy intervention for Latino persons with chronic spine pain in Federally Qualified Health clinics in the southwestern United States. Mixed methods included literature reviews, patient surveys, an Adaptation Advisory Panel, and sequential case series with semistructured interviews.

Currently, an important ecological problem is environmental pollution and its negative impact on living organisms, the consequences of which are deterioration in general health and the manifestation of various diseases, poisoning, endo- and exotoxicosis. Enterosorption method was proposed as a promising method for removing toxic substances from the living organisms using enterosorbents which can absorb various toxic substances of endogenous and exogenous nature in the lumen of the gastrointestinal tract. It has been proposed to use polymer-containing enterosorbents for eliminating of heavy metals from the organism.

Energy correlators that describe energy-weighted distances between two or three particles in a hadronic jet are measured using an event sample of sqrt[s]=13  TeV proton-proton collisions collected by the CMS experiment and corresponding to an integrated luminosity of 36.3  fb^{-1}. The measured distributions are consistent with the trends in the simulation that reveal two key features of the strong interaction: confinement and asymptotic freedom.

Mixtures containing β-glucans were extracted from barley, under both mild and high alkaline conditions, to prepare biodegradable films (MA and HA, respectively), as natural dressings with intrinsic therapeutic properties. An in-depth characterization was performed to evaluate the impact of mild and high alkaline conditions on chemical, physicochemical, and biological features for potential use in wound treatments. Both MA and HA films exhibited a good ability to absorb water and simulate wound fluid, which helps maintain optimal tissue hydration.

Background: The risk of periprosthetic joint infection (PJI) subsequently developing at a second site after an initial PJI has been documented to be approximately 18%-20%. To the best of our knowledge, only a single study has evaluated the incidence in ipsilateral joints and if the risk of infection would be different. While this was the only other study to evaluate this specific subfield, we set to re-evaluate and confirm the incidence of developing a second PJI in the setting of an ipsilateral prosthesis and possible associated risk factors.

Alzheimer's disease (AD) affects both grey and white matter (WM), but considerably more is known about the former. Interestingly, WM disruption has been consistently observed and thoroughly described using imaging modalities, particularly MRI which has shown WM functional disconnections between the hippocampus and other brain regions during AD pathogenesis when early neurodegeneration and synapse loss are also evident. Nonetheless, high-resolution structural and functional analyses of WM during AD pathogenesis remain scarce.
