Ultrasound Education in an Elective Course in the Undergraduate Medical Curriculum Improves Students' Subjective Learning and Clinical Rotation and Residency Preparedness.

Objectives: Studies have demonstrated that students are able to improve their understanding of anatomy, physical exam skills, and clinical knowledge when ultrasound is incorporated into their education. This study investigates whether students enrolled in an elective with significant use of ultrasound (ACS) in their preclinical years subjectively improved their preparedness for clinical rotations, residency, and learning in several subjects.

Methods: This was a retrospective analysis of an anonymous online needs assessment survey sent to 384 third- and fourth-year medical students.

Telling Stories with Data.

The fidelity provided by rich, nuanced ethics consult narratives does not proscribe efforts to advance the profession by using data to assess performance and demonstrate value. While these two approaches have been described as in conflict with one another, the former sets the bar to which the latter should aim; to achieve this, consult data should, minimally, do two things: (1) tell the story of the case, as best as possible, in language easily accessible to both ethicists and non-ethicists alike; and (2) do so in a way that elements of interest can be aggregated, disambiguated, and analyzed. Here we present a three-component system designed with that in mind.

HN001 alters the microbiota composition in the cecum but not the feces in a piglet model.

The probiotic strain HN001 has been shown to have several beneficial health effects for both pediatric and maternal groups, including reduced risk of eczema in infants and gestational diabetes and postnatal depression in mothers. While HN001 appears to modify immune and gut barrier biomarkers, its mode of action remains to be fully elucidated. To gain insights into the role of HN001 on the infant microbiome, the impacts of HN001 supplementation was studied in 10-day old male piglets that were fed either infant formula, or infant formula with HN001 at a low (1.

Social media and the practice of pediatric physical medicine and rehabilitation in the COVID-19 pandemic: A new era in patient-care.

Social media represents a significant source of health information for the public, especially during the COVID-19 pandemic where gatherings are limited. It is important for pediatric physical medicine and rehabilitation physicians to understand how their patients use these platforms in order to educate the public and provide sound medical advice on social media. Given the lack of current guidelines on medical education through social media, the purpose of this paper is to provide an overview of various online social media platforms and describe how they can be utilized to enhance pediatric patient education.

Impacts of Formula Supplemented with Milk Fat Globule Membrane on the Neurolipidome of Brain Regions of Piglets.

The milk fat globule membrane (MFGM) appears to play an important role in infant neurocognitive development; however, its mechanism(s) of action remains unclear. This study aimed to investigate the role of a dietary MFGM supplement on the lipid profiles of different neonatal brain regions. Ten-day-old male piglets (4−5 kg) were fed unsupplemented infant formula (control, n = 7) or an infant formula supplemented with low (4%) or high (8%) levels of MFGM (n = 8 each) daily for 21 days.

Utilizing learning communities to deliver an integrated undergraduate medical education curriculum.

Aim: Learning communities (LCs) have been identified as a structure to support student wellness as well as create a positive learning environment and have been increasingly adopted in undergraduate medical education (UGME). In 2016, Michigan State University College of Human Medicine made curricular changes which integrated basic, social, and clinical sciences. One of the major strategies adopted to deliver this integrated curriculum was to create LCs that served as a central scaffold for students' academic development.

A Polyphenol Enriched Variety of Apple Alters Circulating Immune Cell Gene Expression and Faecal Microbiota Composition in Healthy Adults: A Randomized Controlled Trial.

Polyphenols within fruits and vegetables may contribute to health benefits due to their consumption, with the anthocyanin sub-set also adding colour. The Lemonade™ apple variety has green skin and white flesh, with low anthocyanin content, while some apple varieties have high anthocyanin content in both the skin and flesh. Effects of red compared with white-fleshed apples were studied in healthy human subjects in a randomized, placebo-controlled, cross-over intervention trial.

Comparison Is Not a Zero-Sum Game: Exploring Advanced Measures of Healthcare Ethics Consultation.

Studies across the healthcare spectrum consistently show that sharing and comparing data across institutions improves the quality of patient care. Whether comparing data about healthcare ethics consultation (HCEC) would similarly improve quality is unknown due to the lack of research on HCEC data sharing and comparison. To explore this possibility, we analyzed data from two academic medical centers in the Central-Southern United States that both employ a shared, robust coding system for ethics consultations (N = 703 cases total over 2.

Cohort Profile: The Christchurch IBS cOhort to investigate Mechanisms FOr gut Relief and improved Transit (COMFORT).

Background And Aims: This cross-sectional observational case-control study was initiated in July 2016 with the aim of increasing an understanding of the underlying disease mechanisms in functional gastrointestinal disorders (FGIDs) including irritable bowel syndrome (IBS), functional diarrhoea (FD), and functional constipation (FC). Specific areas of interest include the effect of food, microbiome, host and microbial genetics, metabolome, and psychological variables on unexplained chronic gastrointestinal (GI) symptoms.

Methods: This study recruited consecutive patients who were attending one of two endoscopy centres in Christchurch, New Zealand, for colonoscopy and a subgroup of participants from the general public who did not undergo colonoscopy.

Neuromodulating Influence of Two Electroacupuncture Treatments on Heart Rate Variability, Stress, and Vagal Activity.

Although the clinical use of electro-acupuncture is widespread, the neuromodulating influence of various applied frequencies is not well established. Heart rate variability (HRV), stress and parasympathetic recovery are closely related to health, longevity and vitality in humans. This study was undertaken to determine the influence of different electro-therapy frequencies on various autonomic nervous system markers when applied to a Battlefield Acupuncture Protocol (BFA).

Bovine dairy complex lipids improve in vitro measures of small intestinal epithelial barrier integrity.

Appropriate intestinal barrier maturation is essential for absorbing nutrients and preventing pathogens and toxins from entering the body. Compared to breast-fed infants, formula-fed infants are more susceptible to barrier dysfunction-associated illnesses. In infant formula dairy lipids are usually replaced with plant lipids.

Microcurrent Point Stimulation Applied to Lower Back Acupuncture Points for the Treatment of Nonspecific Neck Pain.

Objectives: Although acupuncture and microcurrent are widely used for chronic pain, there remains considerable controversy as to their therapeutic value for neck pain. We aimed to determine the effect size of microcurrent applied to lower back acupuncture points to assess the impact on the neck pain.

Design: This was a cohort analysis of treatment outcomes pre- and postmicrocurrent stimulation, involving 34 patients with a history of nonspecific chronic neck pain.

Short communication: Early-lactation, but not mid-lactation, bovine lactoferrin preparation increases epithelial barrier integrity of Caco-2 cell layers.

Bovine lactoferrin is an important milk protein with many health-promoting properties, including improving intestinal barrier integrity. Dysfunction of this barrier, commonly referred to as "leaky gut," has been linked to inflammatory and autoimmune diseases. With some processing techniques, lactoferrin isolated from milk collected at the start of the milking season (early lactation) may have lower purity than that isolated from milk collected during the rest of the milking season (mid-lactation) and could result in differences in bioactivity based on the stage of lactation.

Comparative innate immune interactions of human and bovine secretory IgA with pathogenic and non-pathogenic bacteria.

Secretory IgA (SIgA) from milk contributes to early colonization and maintenance of commensal/symbiotic bacteria in the gut, as well as providing defence against pathogens. SIgA binds bacteria using specific antigenic sites or non-specifically via its glycans attached to α-heavy-chain and secretory component. In our study, we tested the hypothesis that human and bovine SIgA have similar innate-binding activity for bacteria.

DC Electroacupuncture Effects on Scars and Sutures of a Patient with Postconcussion Pain.

This case study offers a detailed comparative analysis of the effects of direct-current electroacupuncture (DC-EA) on the autonomic nervous system (ANS), when DC-EA was applied to the cranial sutures and scars of a patient with a history of ischemic stroke and postconcussion syndrome (PCS) pain. A 56-year-old female suffering from severe tremors and debilitating headaches requested acupuncture after conventional biomedicines failed to relieve her symptoms. Evaluations were performed to check the status of 27 ANS functions.

Connecting Patients to Prescription Assistance Programs: Effects on Emergency Department and Hospital Utilization.

Background: Manufacturer prescription assistance programs (PAPs) have been developed to provide medications at little or no cost to eligible patients. There are over 200 PAPs available from pharmaceutical companies, and each may have different eligibility requirements and assistance guidelines. A formalized community-based patient prescription coordinator can help patients navigate these programs by reviewing an applicant's financial information and medication requirements to identify which PAPs are most appropriate.

Lactobacillus fermentum AGR1487 cell surface structures and supernatant increase paracellular permeability through different pathways.

Lactobacillus fermentum is commonly found in food products, and some strains are known to have beneficial effects on human health. However, our previous research indicated that L. fermentum AGR1487 decreases in vitro intestinal barrier integrity.

Human oral isolate Lactobacillus fermentum AGR1487 reduces intestinal barrier integrity by increasing the turnover of microtubules in Caco-2 cells.

Lactobacillus fermentum is found in fermented foods and thought to be harmless. In vivo and clinical studies indicate that some L. fermentum strains have beneficial properties, particularly for gastrointestinal health.

Mismatching amodal redundancy inhibits operant learning in 5-month-old infants.

The current study examined the functional role redundant amodal information plays in an operant learning task in 5-month-old human infants. Prior studies have suggested that both simple and complex learning processes (discrimination, associative conditioning) are facilitated when amodal information is presented redundantly across sensory modalities. These studies, however, did not test whether the amodal information had to be similar across modalities for facilitation to occur.

Identification of novel androgen-regulated pathways and mRNA isoforms through genome-wide exon-specific profiling of the LNCaP transcriptome.

Androgens drive the onset and progression of prostate cancer (PCa) by modulating androgen receptor (AR) transcriptional activity. Although several microarray-based studies have identified androgen-regulated genes, here we identify in-parallel global androgen-dependent changes in both gene and alternative mRNA isoform expression by exon-level analyses of the LNCaP transcriptome. While genome-wide gene expression changes correlated well with previously-published studies, we additionally uncovered a subset of 226 novel androgen-regulated genes.

Global DNA methylation measurement by HPLC using low amounts of DNA.

Epigenetic changes in chromatin structure can influence gene expression without affecting the DNA sequence. The most commonly studied epigenetic modification, DNA methylation, has been implicated in normal tissue development and disease progression, and can be influenced by diet and other environmental factors. Current HPLC methods of determining DNA methylation may require relatively large amounts of DNA (50 μg); as many tissues have low DNA yields, this can be hard to achieve.

Regulation of the androgen receptor by SET9-mediated methylation.

The androgen receptor (AR) is a member of the nuclear hormone receptor family of transcription factors that plays a critical role in regulating expression of genes involved in prostate development and transformation. Upon hormone binding, the AR associates with numerous co-regulator proteins that regulate the activation status of target genes via flux to the post-translational modification status of histones and the receptor. Here we show that the AR interacts with and is directly methylated by the histone methyltransferase enzyme SET9.

Investigating micronutrients and epigenetic mechanisms in relation to inflammatory bowel disease.

Epigenomic regulation, via DNA methylation, histone modification and non-coding RNA, is increasingly recognised as having a key role in normal development and function of an organism, acting to control cellular and tissue growth and differentiation. It is also thought to be involved in many complex diseases now common in the Western world, including cardiovascular disease, type 2 diabetes, obesity and inflammatory bowel disease (IBD). There is a range of evidence to suggest that nutrition plays a vital role in the protection from such diseases.

Metabolomic analysis identifies inflammatory and noninflammatory metabolic effects of genetic modification in a mouse model of Crohn's disease.

Interleukin-10 is an immunosuppressive cytokine involved in the regulation of gastrointestinal mucosal immunity toward intestinal microbiota. Interleukin-10-deficient (IL10(-/-)) mice develop Crohn's disease-like colitis unless raised in germ-free conditions. Previous gas chromatography-mass spectrometry (GC-MS) metabolomic analysis revealed urinary metabolite differences between IL10(-/-) and wildtype C57BL/6 mice.
