    YuHan Chiu & Target Trials

    YuHan Chiu & Target Trials

    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 (https://www.hsph.harvard.edu/miguel-hernan/), and the Kolokotrones Professor of Biostatistics and Epidemiology and focuses on applying causal inference methodologies to dietary data in epidemiological studies. In this episode, Drs. Klatt and Chiu discuss Dr. Chiu’s recent publication in AJCN estimating the effect of a theoretical randomized controlled trial, or ‘target trial’, assessing the impact of adhering to the American Heart Association 2020 Food-Based Dietary Goals. Dr. Chiu provided a really excellent history of the causal inference revolution in epidemiology, and compares and contrasts these approaches with conventional analyses in nutritional epidemiology. 
    In addition to the reading Dr. Chiu’s paper, be sure to check out an associated commentary on the article by AJCN’s own Academic Editor Deirdre Tobias, ScD, and Martin Lajous, MD, ScD.

    New AJCN Journal Sections in Food Systems, Precision Nutrition

    In this episode of AJCN In Press, AJCN’s Inaugural Dennis M. Bier Young Career Editor, Kevin C. Klatt, PhD, RD chats with Jessica Fanzo, PhD and Lorraine Brennan, PhD, both Associate Editors at AJCN respectively leading two new research categories: Food Systems and The Environment, and Nutrigenomics and Precision Nutrition. In this episode, Drs Fanzo and Brennan discuss the rationale behind developing these 2 new journal sections, what prospective authors and readers should know about the sections, and their insights on the future of nutrition research. Learn more about the influential scholarship of these two distinguished editors and podcast guests in the “Meet the Editors (https://academic.oup.com/ajcn/pages/meet_the_ajcn_editors)” section of the AJCN Website.
    Interested in more specifics about these two new research categories? Check out the accompanying AJCN introductory manuscripts authored by Dr Fanzo, Dr Brennan, and colleagues.

    Carbon Isotope Ratios of Amino Acids As Biomarkers of Sugar Intake

    Carbon Isotope Ratios of Amino Acids As Biomarkers of Sugar Intake

    In this episode of AJCN In Press, AJCN’s Inaugural Dennis M. Bier Young Career Editor, Kevin C. Klatt, PhD, RD chats with PhD candidate, Jessica Johnson, at the Institute of Arctic Biology at the University of Alaska Fairbanks. Ms. Johnson is a member of the Diane M. O’Brien Laboratory and focuses her research on how we can utilize naturally occurring stable isotope ratios in circulating metabolites as biomarkers of dietary intake. In this episode, we discuss Ms. Johnson’s recent first author publication in AJCN, “The carbon isotope ratios of nonessential amino acids identify sugar-sweetened beverage (SSB) consumers in a 12-wk inpatient feeding study of 32 men with varying SSB and meat exposures“. We dive deep into this really novel study, touching on stable isotopes, controlled feeding trials, essential and non-essential amino acids, and emerging biomarkers of intake for use in experimental and observational nutrition studies.
    Previous related work from the O’Brien Laboratory (https://academic.oup.com/ajcn/article/110/6/1306/5568461) published in AJCN may be of interest to readers, as well as a related commentary on the use of stable isotope ratios in nutritional epidemiology (https://academic.oup.com/ajcn/article/110/6/1265/5571774).

    Inflammatory Bowel Disease and Food-Related Quality of Life with Kevin Whelan

     
    In this episode of AJCN In Press, we travel across the pond, so to speak, and chat with Professor Kevin Whelan, Professor of Dietetics and Head of Department of Nutritional Sciences at King’s College London, United Kingdom about his recent publication in AJCN. Dr. Whelan is a renowned investigator in the fields of gastroenterology and dietetics, having undertaken and led extensive research on pre- and pro-biotics, fiber, the gut microbiome, and gastrointestinal health and disease. His research and teaching efforts have received national and international recognition, including Dr. Whelan being appointed as a Fellow of the British Dietetic Association and delivering the prestigious Dr. Elsie Widdowson Memorial Lecture.
