Genomic prediction is a powerful approach for improving genetic gain and shortening the breeding cycles in animal and crop breeding programs. A series of statistical and machine learning models has been developed to increase the prediction performance continuously. However, the application of these models requires advanced R programming skills and command-line tools to perform quality control, format input files, and install packages and dependencies, posing challenges for breeders.

Objectives: This study aims to examine the association between state Medicaid coverage of podiatry services and the outcomes of beneficiaries with new diabetic foot ulcers (DFUs).
Methods: Medicaid beneficiaries who developed a DFU between 2010 and 2015 were identified using the PearlDiver claims database. The states were categorized into covered states (CS) and non-covered states (NCS) based on podiatric coverage during the study period.
Vertigo is a common symptom of various diseases that affects a large number of people worldwide. Current leading treatments for intractable peripheral vertigo are to intratympanically inject ototoxic drugs such as gentamicin to attenuate the semicircular canal function but inevitably cause hearing injury. Photodynamic therapy (PDT) is a noninvasive therapeutic approach by precisely targeting the diseased tissue.

Purpose: To investigate the characteristics and rate of sociodemographic variables reported in randomized controlled trials (RCTs) studying platelet-rich plasma (PRP) injections in the treatment of knee osteoarthritis (OA).
Methods: In January 2024, PubMed, Scopus, and Web of Science databases were queried for the phrase "Platelet-Rich Plasma Knee Osteoarthritis." Included studies were RCTs investigating PRP use in knee OA published in English between 2012 and 2023.

Background: Sleep disturbances are a major public health concern in the United States, leading to adverse health outcomes. In the working population, job strain has been identified as an important risk factor for sleep disturbances, but evidence from the United States remained limited. This study aimed to examine longitudinal associations between job strain and sleep disturbances in the United States, with a focus on the alternative formulations of job strain.

Transcutaneous auricular vagus nerve stimulation (taVNS) has been tested as a strategy to facilitate fear extinction learning based on the hypothesis that taVNS increases central noradrenergic activity. Four studies out of six found taVNS to enhance extinction learning especially at the beginning of extinction. Facilitatory effects of taVNS were mainly observed in US expectancy, less in fear-potentiated startle (FPS), and not in the skin conductance response (SCR).

The calvarial bones of the infant skull are linked by transient fibrous joints known as sutures and fontanelles, which are essential for skull compression during birth and expansion during postnatal brain growth. Genetic conditions caused by pathogenic variants in FGFR2, such as Apert, Pfeiffer, and Crouzon syndromes, result in calvarial deformities due to premature suture fusion and a persistently open anterior fontanelle (AF). In this study, we investigated how Fgfr2 regulates AF closure by leveraging mouse genetics and single-cell transcriptomics.

Objectives: To identify landmarks in ultrasound periodontal images and automate the image-based measurements of gingival recession (iGR), gingival height (iGH), and alveolar bone level (iABL) using machine learning.
Methods: We imaged 184 teeth from 29 human subjects. The dataset included 1580 frames for training and validating the U-Net CNN machine learning model, and 250 frames from new teeth that were not used in training for testing the generalization performance.

Importance: The Southern Community Cohort Study (SCCS) Polypill Trial showed that a cardiovascular polypill (a single pill containing a statin and 3 half-standard dose antihypertensive medications) effectively controls cardiovascular disease (CVD) risk factors in a majority Black race and low-income population. The cost-effectiveness of polypill treatment in this population has not been previously studied.
Objective: To determine the cost-effectiveness of the cardiovascular polypill.

Opioid receptors, a subfamily of G protein-coupled receptors (GPCRs), are key therapeutic targets. In the canonical GPCR activation model, agonist binding is required for receptor-G protein complex formation, while antagonists prevent G protein coupling. However, many GPCRs exhibit basal activity, allowing G protein association without an agonist.

Background: Remote monitoring using electronic patient-reported outcomes (ePROs) may help identify immune-related adverse events (irAEs) and direct self-management. There is no consensus regarding thresholds to alert providers about potentially severe irAEs or when to instigate evidence-based self-management. We aimed to develop consensus around alert thresholds and self-management advice for side-effects suggestive of an irAE which can be deployed as part of remote monitoring systems.

Bathymetry critically influences the intrusion of warm Circumpolar Deep Water onto the continental shelf and under ice shelf cavities in Antarctica, thereby forcing ice melting, grounding line retreat, and sea level rise. We present a novel and comprehensive bathymetry of Antarctica that includes all ice shelf cavities and previously unmeasured continental shelf areas. The new bathymetry is based on a 3D inversion of a circumpolar compilation of gravity anomalies constrained by measurements from the International Bathymetric Chart of the Southern Ocean, BedMachine Antarctica, and discrete seafloor measurements from seismic and ocean robotic probes.

Background/objective: There is limited knowledge on how diet affects the epigenome of children. Ultra-processed food (UPF) consumption is emerging as an important factor impacting health, but mechanisms need to be uncovered. We therefore aimed to assess the association between UPF consumption and DNA methylation in children.

Background: Approximately one in six children has a disability, and effective, evidence-based rehabilitation can ameliorate the impact of these conditions over the lifespan. However, implementing interventions in real-world settings remains a challenge. This scoping review aimed to summarize the characteristics, implementation strategies, and outcomes of implementation studies in pediatric rehabilitation.

Backgrounds: Digital, online assessments are efficient means to detect early cognitive decline, but few studies have investigated the relationship between remotely collected subjective cognitive change and cognitive decline. We hypothesized that the Everyday Cognition Scale (ECog), a subjective change measure, predicts longitudinal change in cognition in the Brain Health Registry (BHR), an online registry for neuroscience research.
Methods: This study included BHR participants aged 55 + who completed both the baseline ECog and repeated administrations of the CANTAB Paired Associates Learning (PAL) visual learning and memory test.

Policy interventions and technological advances are mitigating emissions of air pollutants from motor vehicles. As a result, vehicle fleets are expected to progressively combust fuel more efficiently, with a declining ratio of carbon monoxide to carbon dioxide (CO/CO) in their emissions. We assess trends in traffic combustion efficiency in Los Angeles (LA) and Salt Lake City (SLC) by measuring changes in summertime on-road CO/CO between 2013 and 2021 using mobile observations.

Individuals with Pediatric Acute-onset Neuropsychiatric Syndrome (PANS), an immune-modulated disorder, experience exacerbation-related neuropsychiatric symptoms, functional impairments, and high rates of developmental diagnosis. The literature describes links between giftedness and mental illness, and giftedness and autoimmune disorders. We sought to explore rates of giftedness among children with PANS as perceived by their caregivers, and to examine whether giftedness was related to PANS symptom severity, persistence, or duration.
