RESUMEN

For decades, there have been government funded services to provide healthcare telephonically to remote sites both on the earth and in the air. This capability has evolved into what we now know as telehealth. The use of telehealth dramatically accelerated as a result of concerns for patient and healthcare provider safety during the SARS-CoV2 pandemic. Similarly, concerns regarding transmission of infection have required medical schools to provide robust, easily accessible virtual education options. At short notice, faculties have had to develop new telehealth focused curriculum components. However, telehealth, online education, and internet enabled research should not be simply a new way to do traditional jobs but rather, an opportunity to take advantage of how technology can best be used to develop new and better ways to provide care, educate health care providers, and support research.

RESUMEN

The incidence of preterm birth exceeds 10% worldwide. There are significant disparities in the frequency of preterm birth among populations within countries, and women of African ancestry disproportionately bear the burden of risk in the United States. In the present study, we report a community resource that includes 'omics' data from approximately 12,000 samples as part of the integrative Human Microbiome Project. Longitudinal analyses of 16S ribosomal RNA, metagenomic, metatranscriptomic and cytokine profiles from 45 preterm and 90 term birth controls identified harbingers of preterm birth in this cohort of women predominantly of African ancestry. Women who delivered preterm exhibited significantly lower vaginal levels of Lactobacillus crispatus and higher levels of BVAB1, Sneathia amnii, TM7-H1, a group of Prevotella species and nine additional taxa. The first representative genomes of BVAB1 and TM7-H1 are described. Preterm-birth-associated taxa were correlated with proinflammatory cytokines in vaginal fluid. These findings highlight new opportunities for assessment of the risk of preterm birth.

RESUMEN

The microbiome of the female reproductive tract has implications for women's reproductive health. We examined the vaginal microbiome in two cohorts of women who experienced normal term births: a cross-sectionally sampled cohort of 613 pregnant and 1,969 non-pregnant women, focusing on 300 pregnant and 300 non-pregnant women of African, Hispanic or European ancestry case-matched for race, gestational age and household income; and a longitudinally sampled cohort of 90 pregnant women of African or non-African ancestry. In these women, the vaginal microbiome shifted during pregnancy toward Lactobacillus-dominated profiles at the expense of taxa often associated with vaginal dysbiosis. The shifts occurred early in pregnancy, followed predictable patterns, were associated with simplification of the metabolic capacity of the microbiome and were significant only in women of African or Hispanic ancestry. Both genomic and environmental factors are likely contributors to these trends, with socioeconomic status as a likely environmental influence.

RESUMEN

OBJECTIVE: To determine the association between family-centered rounds (FCR) and medical student knowledge acquisition as assessed by the National Board of Medical Examiners (NBME) pediatric subject (shelf) exam. METHODS: A retrospective cohort study was conducted of third-year medical students who graduated from Virginia Commonwealth University School of Medicine between 2009 and 2014. This timeframe represented the transition from 'traditional' rounds to FCR on the pediatric inpatient unit. Data collected included demographics, United States Medical Licensing Examination (USMLE) Step 1 and 2 scores, and NBME subject examinations in pediatrics (PSE), medicine (MSE), and surgery (SSE). RESULTS: Eight hundred and sixteen participants were included in the analysis. Student performance on the PSE could not be statistically differentiated from performance on the MSE for any year except 2011 (z-score=-0.17, p=0.02). Average scores on PSE for years 2009, 2010, 2013, and 2014 were significantly higher than for SSE, but not significantly different for all other years. The PSE was highly correlated with USMLE Step 1 and Step 2 examinations (correlation range 0.56-0.77) for all years. CONCLUSIONS: Our results showed no difference in PSE performance during a time in which our institution transitioned to FCR. These findings should be reassuring for students, attending physicians, and medical educators.
