In this episode, Kevin C. Klatt, PhD, RD (he/him) speaks with 2 highly distinguished nutrition physician clinicians and researchers, neonatologist Steven Abrams, MD and pediatric gastroenterologist Robert J. Shulman, MD about their recent paper, “What would happen in the United States if there were no cow milk-based preterm infant nutritional products: Historical perspective and evaluation of nutrient-related challenges”. This episode discusses the challenges in feeding preterm infants and the roles of human milk, fortifiers and cow’s milk based nutritional products in the context of recent litigation and potentially future compromised access to preterm infant nutrition products.

In this episode, Kevin C. Klatt, PhD, RD (he/him) speaks with Section Editor Nancy Krebs MD MS, and Stephanie Waldrop MD MPH, both from the Section of Nutrition at the University of Colorado Anschutz Medical Center. Drs Kreb and Waldrop discuss their recent publication, the inaugural case in the new “Nutrition for the Clinician” series, detailing a case of a pediatric patient presenting with SARS-CoV-2 (COVID-19) and additional unexplained symptoms that resulted in consulting the nutrition team. Drs Kreb and Waldrop discuss the events leading up to their consultation, their approach to assessment and diagnosis of the patient, and ultimate intervention and monitoring. The case contains numerous teaching points, including nutritional adequacy on a ketogenic diet and the challenges of nutrition assessment.

In this episode, Early Career Editor Kevin C. Klatt, PhD, RD speaks with Briana Stephenson, PhD (she/her/hers), an Assistant Professor in the Departments of Biostatistics at the Harvard TH Chan School of Public Health, about her recent publication, “Racial and ethnic heterogeneity in diets of low-income adult females in the United States: results from National Health and Nutrition Examination Surveys from 2011 to 2018” in the American Journal of Clinical Nutrition. Dr Stephenson discusses her research on robust profile clustering as an extension of latent class models to define dietary patterns in population subgroups, focusing in this analysis on low-income female adults to identify racial and ethnic differences in dietary patterns.

In this episode, Early Career Editor Kevin C. Klatt, PhD, RD speaks with Harry Jarrett, PhD, Helene McNulty, PhD, RD, MRIA and Mary Ward, PhD, RD about their recent publication, “Vitamin B6 and riboflavin, their metabolic interaction and relationship with MTHFR genotype, in adults aged 18-102 years” in the American Journal of Clinical Nutrition. The authors discuss the rationale for looking at Vitamin B2 and B6 status marker interactions, including MTHFR genotype, and provide epidemiological evidence in support of riboflavin functional status (the erythrocyte glutathione reductase activation coefficient or EGRAC) being a determinant of Vitamin B6 (PLP) status.

In this episode of AJCN In Press, AJCN’s Inaugural Dennis M. Bier Young Career Editor, Kevin C. Klatt, PhD, RD chats with YuHan Chiu, MD, PhD, a postdoctoral fellow in the Department of Epidemiology at Harvard University. Dr. Chiu is a fellow in the laboratory of Miguel Hernán, MD, DrPH, and the Kolokotrones Professor of Biostatistics and Epidemiology and focuses on applying causal inference methodologies to dietary data in epidemiological studies.
