Perceptions of Barriers and Facilitators to Becoming a Medical Professional Among Underrepresented Undergraduate and Postbaccalaureate Learners.

OBJECTIVE: To assess underrepresented undergraduate and postbaccalaureate learners' perceptions of (1) the medical field, (2) barriers that might prevent individuals from pursuing professional medical careers, and (3) resources that assist in overcoming these barriers. PARTICIPANTS AND METHODS: A qualitative study with focus groups was designed to achieve the objective. Participants were recruited from a community initiative to provide early exploration of the medical field to disadvantaged and minority individuals. Thirty-five individuals voluntarily participated in semistructured interviews. Audio from the interviews was analyzed using a qualitative descriptive approach and thematic analysis. This study was conducted from October 20, 2018, to April 6, 2019. RESULTS: Participants identified multiple characteristics related to the health care work environment and desirable attributes of health care personnel. The following barriers were identified: financial burden, lacking knowledge of the path to becoming a medical professional, inadequate social support, and lacking the metrics of a competitive candidate. Resources identified by participants to overcome barriers included professional networks and programmatic considerations. CONCLUSION: The study participants discussed negative and positive aspects of the health care environment, such as implicit and explicit biases and attributes that promote or sustain success. Participants expounded on financial, academic, social, and personal factors as barriers to success. In regard to resources that were believed to be helpful to mitigate barriers and promote success, participants commented on activities that simulate a professional medical environment, include networking with medical personnel, support well-being, and provide exposure to structured information on the process of obtaining professional medical training.

Disease-associated metabolic alterations that impact satellite cells and muscle regeneration: perspectives and therapeutic outlook.

Many chronic disease patients experience a concurrent loss of lean muscle mass. Skeletal muscle is a dynamic tissue maintained by continuous protein turnover and progenitor cell activity. Muscle stem cells, or satellite cells, differentiate (by a process called myogenesis) and fuse to repair and regenerate muscle. During myogenesis, satellite cells undergo extensive metabolic alterations; therefore, pathologies characterized by metabolic derangements have the potential to impair myogenesis, and consequently exacerbate skeletal muscle wasting. How disease-associated metabolic disruptions in satellite cells might be contributing to wasting is an important question that is largely neglected. With this review we highlight the impact of various metabolic disruptions in disease on myogenesis and skeletal muscle regeneration. We also discuss metabolic therapies with the potential to improve myogenesis, skeletal muscle regeneration, and ultimately muscle mass.

Comparison of bleach, acetic acid, and other topical anti-infective treatments in pediatric atopic dermatitis: A retrospective cohort study on antibiotic exposure.

BACKGROUND/OBJECTIVES: Skin infection is common in atopic dermatitis (AD), often necessitating treatment with systemic antibiotics. Topical adjunctive therapies such as dilute bleach baths are increasingly recommended, and topical dilute acetic acid (AA) has not been widely studied. The objective of this study was to evaluate whether various topical anti-infective bathing recommendations were associated with decreased systemic antibiotic exposure in pediatric AD, as well as evaluate topical anti-infective recommendations over time within our institution. METHODS: Clinical data were extracted from charts of pediatric patients from 1/1/2000 to 12/31/2005 and 1/1/2009 to 12/31/2014 who visited outpatient dermatology clinics at Mayo Clinic, Rochester, a tertiary referral center. Recommendations for topical anti-infectives (dilute AA, dilute bleach, other, or none) at any time after patient had clinically proven or suspected AD superinfection were recorded as exposures to topical anti-infective. Primary outcome was the number of systemic antibiotic courses in a 1-year period. RESULTS: Of 1111 patients with AD, 753 met inclusion criteria (303 in 2000-2005; 450 in 2009-2014). Of these, 351 (46.6%) had culture-proven or clinically suspected superinfection. Topical anti-infective recommendations increased between the time periods (23.3% to 79.2%; P < 0.001) and number of courses of systemic antibiotics decreased (1.9 per year vs 1.5 per year, P = 0.010). Number of systemic antibiotic courses did not differ between those who received bathing recommendations and those who did not, nor between different anti-infective groups (P = 0.398). CONCLUSIONS: Practice behaviors have changed, and topical anti-infectives are now commonly recommended. Neither dilute AA nor bleach baths were associated with fewer subsequent exposures to systemic antibiotics in the treatment of pediatric AD.

Metabolomic Analyses Reveal Extensive Progenitor Cell Deficiencies in a Mouse Model of Duchenne Muscular Dystrophy.

Duchenne muscular dystrophy (DMD) is a musculoskeletal disorder that causes severe morbidity and reduced lifespan. Individuals with DMD have an X-linked mutation that impairs their ability to produce functional dystrophin protein in muscle. No cure exists for this disease and the few therapies that are available do not dramatically delay disease progression. Thus, there is a need to better understand the mechanisms underlying DMD which may ultimately lead to improved treatment options. The muscular dystrophy (MDX) mouse model is frequently used to explore DMD disease traits. Though some studies of metabolism in dystrophic mice exist, few have characterized metabolic profiles of supporting cells in the diseased environment. Using nontargeted metabolomics we characterized metabolic alterations in muscle satellite cells (SCs) and serum of MDX mice. Additionally, live-cell imaging revealed MDX-derived adipose progenitor cell (APC) defects. Finally, metabolomic studies revealed a striking elevation of acylcarnitines in MDX APCs, which we show can inhibit APC proliferation. Together, these studies highlight widespread metabolic alterations in multiple progenitor cell types and serum from MDX mice and implicate dystrophy-associated metabolite imbalances in APCs as a potential contributor to adipose tissue disequilibrium in DMD.
