Developmental programming

Shifting to a competency-based (CBME) and not time-bound curricular structure is challenging in the undergraduate medical education (UME) setting for a number of reasons. There are few examples of broad scale CBME-driven interventions that make the UME program less time-bound. However, given the range of student ability and varying speed of acquisition of competencies, this is an area in need of focus. This paper describes a model that uses the macro structure of a UME program to make UME curricula less time-bound, and driven more by student competency acquisition and individual student goals...

INTRODUCTION: Doctor of Physical Therapy (DPT) education programs have been charged with developing a culturally competent health care workforce to better meet the needs of diverse communities and reduce health inequities. The purpose of this longitudinal, quasi-experimental educational intervention study was to examine the effects of an integrated DPT program curriculum on student cultural competence at a public, midsize, midwestern university. REVIEW OF LITERATURE: There is an abundance of research on conceptual models and frameworks for the development of cultural competence within health care education with many studies relying on self-perception to measure outcomes...

BACKGROUND: The Modified Checklist for Autism in Toddlers (M-CHAT) is a common pediatric screening tool with mixed accuracy findings. Prior evidence supports M-CHAT screening for developmental concerns, especially in toddlers born preterm. This study examined M-CHAT accuracy in a large, nationwide sample. METHODS: 3393 participants from the Environmental influences on Child Health Outcomes (ECHO) program were included. Harmonized M-CHAT (M-CHAT-H) results were compared with parent-reported autism diagnosis and autism-related characteristics to assess accuracy for term and preterm children, together and separately...

STUDY QUESTION: How do transcriptomics vary in haploid human androgenote embryos at single cell level in the first four cell cycles of embryo development? SUMMARY ANSWER: Gene expression peaks at the fourth cell cycle, however some androcytes exhibit unique transcriptional behaviors. WHAT IS KNOWN ALREADY: The developmental potential of an embryo is determined by the competence of the oocyte and the sperm. However, studies of the contribution of the paternal genome using pure haploid androgenotes are very scarce...

From insects to humans, the nervous system generates complex behaviors mediated by distinct neural circuits that are composed of diverse cell types. During development, the spatiotemporal gene expression of the neural progenitors expands the diversity of neuronal and glial subtypes. Various neural stem cell-intrinsic and -extrinsic gene programs have been identified that are thought to play a major role in generating diverse neuronal and glial cell types. Drosophila has served as an excellent model system for discovering the fundamental principles of nervous system development and function...

The Ala Wai Canal is an artificial waterway in the tourist district of Waikiki in Honolulu, HI. Originally built to collect runoff from industrial, residential, and green spaces dedicated to recreation, the Ala Wai Canal has since experienced potent levels of toxicity due to this runoff entering the watershed and making it hazardous for both marine life and humans at current concentration, including Danio rerio (zebrafish). A community of learners at educations levels from high school to postbaccalaureate from Oahu, HI was connected through the Consortium for Increasing Research and Collaborative Learning Experiences (CIRCLE) distance research program...

Zebrafish have been used as an education tool for students of all ages and can be used in many learning environments to teach different fields of science. In this study, we focus on the biology of zebrafish. We describe an educational program within a weeklong science camp for students between 12 and 14 years old. The methodology described is based on running annual science camps over an 11-year period. In these camps, students learnt about the developmental stages of zebrafish, as well as general zebrafish biology, husbandry, ecology, behavior, and reproduction...

The goal of the University of Wisconsin-Milwaukee WInSTEP SEPA program is to provide valuable and relevant research experiences to students and instructors in diverse secondary educational settings. Introducing an online experience allows the expansion of a proven instructional research program to a national scale and removes many common barriers. These can include lack of access to zebrafish embryos, laboratory equipment, and modern classroom facilities, which often deny disadvantaged and underrepresented students from urban and rural school districts valuable inquiry-based learning opportunities...

PURPOSE: Children with developmental language disorder frequently have difficulty with both academic success and language learning and use. This clinical focus article describes core principles derived from a larger program of research (National Science Foundation 1748298) on language intervention combined with science instruction for preschoolers. It serves as an illustration of a model for integrating language intervention with curricular content delivery. METHOD: We present a five-step model for a speech-language pathologist and other school professionals to follow to (a) understand the grade-level core curriculum objectives; (b) align intervention targets with the curriculum; (c) select a therapy approach that aligns with both goals and curricular content, and (d) methods for implementing the intervention; and (e) verify that both the intervention and the curriculum have been provided in accordance with best practices...

BACKGROUND: The Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC:0-5TM ) is widely used in many Western countries. For Russian specialists, such classification represents a relatively new tool for the comprehensive diagnosis of mental disorders in children from birth to the five-year-old threshold. The purpose for presenting this case study report is to showcase the practical application of the DC:0-5TM . AIM: This study aims to illustrate the diagnostic process according to the DC:0-5TM criteria using the example of a specific clinical case report involving the collaborative efforts of two specialists: a child psychiatrist and a clinical child psychologist...

BACKGROUND: The developmental size of the cervical spinal canal varies considerably. Neural compression and injury are more likely with a developmentally small spinal canal. This study was designed to develop a population reference range for developmental cervical spinal canal size for the Hong Kong population. METHODS: Prospective study of 522 ambulatory patients (256 males, 266 females, mean age 55±18 years; range, 20-89 years) who underwent computed tomography (CT) neck examinations...

This study aims to present a more systematic and developmental research direction by classifying animal-mediation related research trends published in Korea. We analyzed the research trends of 68 domestic animal-mediation programs published in 26 journals over the past 24 years under the premise of the necessity of animal-assisted therapy, which considered a very effective intervention method in the practice areas of various subjects. Therefore, this study examines the year of publication of animal-mediation related research conducted in various academic fields from 1998 to 2022, research data sources, characteristics of research subjects, types of interventions and research topics, research design and intervention sessions, intervention methods, and ethical consideration statements...

BACKGROUND: Child development is shaped throughout the first years of life through the interaction of genetics and the environment. Bayley-III is valuably used to determine early developmental delay (DD). The aim of this study was to detect the differences in performance of a sample of apparently healthy Egyptian infants and toddlers on the Bayley-III scales in relation to their age and gender. METHODS: This was a cross-sectional study. Bayley scales were applied to 270 of the 300 recruited children following the inclusion criteria; to avoid potential risk factors affecting development...

BACKGROUND: Good postural stability control is dependent upon the complex integration of incoming sensory information (visual, somatosensory, vestibular) with neuromotor responses that are constructed in advance of a voluntary action or in response to an unexpected perturbation. AIMS: To examine whether differences exist in how sensory inputs are used to control standing balance in children with and without Prader-Willi syndrome (PWS). METHODS AND PROCEDURES: In this cross-sectional study, 18 children with PWS and 51 children categorized as obese but without PWS (without PWS) ages 8-11 completed the Sensory Organization Test®...

BACKGROUND: Children with Generalized Joint Hypermobility (GJH) may have a motor developmental delay in the early period and subluxation, fatigue, autonomic dysfunction, and pain arising from ligaments and other soft tissues in advanced ages. Additionally, there is a loss of proprioceptive sensation in children and adults with GJH. AIMS: This study aimed to evaluate sensory processing skills in toddlers with GJH. STUDY DESIGN: A cross-sectional study...

The adverse influence of maternal obesity on offspring metabolic health throughout the life-course is a significant public health challenge with few effective interventions. We examined if black bean powder (BBP) supplementation to a high-calorie maternal pregnancy diet or a postnatal offspring diet could offer protection against the metabolic programming of metabolic disease risk in adult offspring. Female Sprague Dawley rats were randomly assigned to one of three diets (n = 10/group) for a 3-week pre-pregnancy period and throughout gestation and lactation: (i) a low-caloric control diet (CON); (ii) a high-caloric obesity-inducing diet (HC); or (iii) the HC diet with 20% black bean powder (HC-BBP)...

Sulfur (S), one of the crucial macronutrients, plays a pivotal role in fundamental plant processes and the regulation of diverse metabolic pathways. Additionally, it has a major function in plant protection against adverse conditions by enhancing tolerance, often interacting with other molecules to counteract stresses. Despite its significance, a thorough comprehension of how plants regulate S nutrition and particularly the involvement of phytohormones in this process remains elusive. Phytohormone signaling pathways crosstalk to modulate growth and developmental programs in a multifactorial manner...

Changes in the components, variety, metabolism, and products of microbiomes, particularly of the gut microbiome (GM), have been revealed to be closely associated with the onset and progression of numerous human illnesses, including hematological neoplasms. Among the latter pathologies, there is acute lymphoblastic leukemia (ALL), the most widespread malignant neoplasm in pediatric subjects. Accordingly, ALL cases present a typical dysfunctional GM during all its clinical stages and resulting inflammation, which contributes to its progression, altered response to therapy, and possible relapses...

Originally discovered in C. elegans , LIN28 is an evolutionarily conserved zinc finger RNA-binding protein (RBP) that post-transcriptionally regulates genes involved in developmental timing, stem cell programming, and oncogenesis. LIN28 acts via two distinct mechanisms. It blocks the biogenesis of the lethal-7 (let-7) microRNA (miRNA) family, and also directly binds messenger RNA (mRNA) targets, such as IGF-2 mRNA, and alters downstream splicing and translation events. This review focuses on the molecular mechanism of LIN28 repression of let-7 and current strategies to overcome this blockade for the purpose of cancer therapy...

Soil salinity imposes osmotic, ionic, and oxidative stresses on plants, resulting in growth inhibition, developmental changes, metabolic adaptations, and ion sequestration or exclusion. Identifying salinity-tolerant resources and understanding physiological and molecular mechanisms of salinity tolerance could lay a foundation for the improvement of salinity tolerance in rice. In this study, a series of salinity-tolerance-related morphological and physiological traits were investigated in 46 rice genotypes, including Sea Rice 86, to reveal the main strategies of rice in responding to salinity stress at the seedling stage...
