Association Of Baseline Inflammatory Biomarkers With Cancer Mortality In The Regards Cohort, Tomi Akinyemiju, Justin X. Moore, Maria Pisu, Michael Goodman, Virginia J. Howard, Monika Safford, Susan C. Gilchrist, Mary Cushman, Leann Long, Suzanne E. Judd

Open Access Publications

This study examines the association between inflammatory biomarkers and risk of cancer mortality by race. Data were obtained from 1,856 participants in the prospective REGARDS cohort who were cancer-free at baseline, and analyzed in relation to cancer mortality prospectively. Biomarkers were log-transformed and categorized into tertiles due to non-normal distributions, and Cox proportional hazard regression models were utilized to compute hazard ratios with 95% confidence intervals using robust sandwich methods. Individuals in the highest tertile of IL-6 had over a 12-fold increased risk of cancer mortality (HR: 12.97, 95% CI: 3.46-48.63); those in the highest tertile of IL-8 had over …

Low-Carbohydrate Diets For Gestational Diabetes, Sarah S Farabi, Teri L Hernandez

Open Access Publications

Nutrition therapy provides the foundation for treatment of gestational diabetes (GDM), and has historically been based on restricting carbohydrate (CHO) intake. In this paper, randomized controlled trials (RCTs) are reviewed to assess the effects of both low- and higher CHO nutrition approaches in GDM. The prevailing pattern across the evidence underscores that although CHO restriction improves glycemia at least in the short-term, similar outcomes could be achievable using less restrictive approaches that may not exacerbate IR. The quality of existing studies is limited, in part due to dietary non-adherence and confounding effects of treatment with insulin or oral medication. Recent …

Tomasz Dangel Oral History.

Pediatric Palliative Care Oral History Project

Dr. Dangel begins the interview describing his experiences as a pediatric anesthesiologist witnessing children dying while receiving unnecessary aggressive treatment during the end-of-life. He also describes several pivotal experiences learning about and seeing other countries develop pediatric hospices. When he brought back his experiences to his home institution, he was not well received and consequently left to seek an environment to nurture his vision for pediatric palliative and hospice care. Dr. Dangel comments that this was not his first time bringing new ideas into Polish medicine since he "introduced the modern techniques of regional anesthesia and analgesia in children," in …

A Sparse Covarying Unit That Describes Healthy And Impaired Human Gut Microbiota Development, Arjun S Raman, Jeanette L Gehrig, Siddarth Venkatesh, Hao-Wei Chang, Matthew C Hibberd, Sathish Subramanian, Michael J Barratt, Jeffrey I Gordon, Et Al

Open Access Publications

Characterizing the organization of the human gut microbiota is a formidable challenge given the number of possible interactions between its components. Using a statistical approach initially applied to financial markets, we measured temporally conserved covariance among bacterial taxa in the microbiota of healthy members of a Bangladeshi birth cohort sampled from 1 to 60 months of age. The results revealed an "ecogroup" of 15 covarying bacterial taxa that provide a concise description of microbiota development in healthy children from this and other low-income countries, and a means for monitoring community repair in undernourished children treated with therapeutic foods. Features of …

Open Access Publications

To examine the contributions of impaired gut microbial community development to childhood undernutrition, we combined metabolomic and proteomic analyses of plasma samples with metagenomic analyses of fecal samples to characterize the biological state of Bangladeshi children with severe acute malnutrition (SAM) as they transitioned, after standard treatment, to moderate acute malnutrition (MAM) with persistent microbiota immaturity. Host and microbial effects of microbiota-directed complementary food (MDCF) prototypes targeting weaning-phase bacterial taxa underrepresented in SAM and MAM microbiota were characterized in gnotobiotic mice and gnotobiotic piglets colonized with age- and growth-discriminatory bacteria. A randomized, double-blind controlled feeding study identified a lead MDCF …

Stacy Orloff Oral History.

Pediatric Palliative Care Oral History Project

Dr. Stacy Orloff begins the interview describing her experience after completing her MSW degree and one pivotal serendipitous event: she looked at the classified ads in the newspaper for the first time and found a job opening for a children's program in her local hospice. After she took that position, she found that all her training in life led up to being a children's advocate in the hospice setting. Dr. Orloff reflects on the beginning of the community-based hospice movement that now seems to provide fewer services than it was once able to due to the regulatory policies. She also …

Disseminating And Implementing A Lifestyle-Based Healthy Weight Program For Mothers In A National Organization: A Study Protocol For A Cluster Randomized Trial, Rachel G Tabak, Cynthia D Schwarz, Allison Kemner, Kenneth B Schechtman, Karen Steger-May, Veronda Byrth, Debra Haire-Joshu

Open Access Publications

BACKGROUND: Excessive weight gain among young adult women age 18-45 years is an alarming and overlooked trend that must be addressed to reverse the epidemics of obesity and chronic disease. During this vulnerable period, women tend to gain disproportionally large amounts of weight compared to men and to other life periods. Healthy Eating and Active Living Taught at Home (HEALTH) is a lifestyle modification intervention developed in partnership with Parents as Teachers (PAT), a national home visiting, community-based organization with significant reach in this population. HEALTH prevented weight gain, promoted sustained weight loss, and reduced waist circumference. PAT provides parent-child …

The Current State Of Animal Models And Genomic Approaches Towards Identifying And Validating Molecular Determinants Of Mycobacterium Tuberculosis Infection And Tuberculosis Disease, Allison N Bucsan, Smriti Mehra, Shabaana A Khader, Deepak Kaushal

2010-2019 OA Pubs

Animal models are important in understanding both the pathogenesis of and immunity to tuberculosis (TB). Unfortunately, we are beginning to understand that no animal model perfectly recapitulates the human TB syndrome, which encompasses numerous different stages. Furthermore, Mycobacterium tuberculosis infection is a very heterogeneous event at both the levels of pathogenesis and immunity. This review seeks to establish the current understanding of TB pathogenesis and immunity, as validated in the animal models of TB in active use today. We especially focus on the use of modern genomic approaches in these models to determine the mechanism and the role of specific …

The heritability of nicotine dependence based on family studies is substantial. Nevertheless, knowledge of the underlying genetic architecture remains meager. Our aim was to identify novel genetic variants responsible for interindividual differences in smoking behavior. We performed a genome-wide association study on 1715 ever smokers ascertained from the population-based Finnish Twin Cohort enriched for heavy smoking. Data imputation used the 1000 Genomes Phase I reference panel together with a whole genome sequence-based Finnish reference panel. We analyzed three measures of nicotine addiction-smoking quantity, nicotine dependence and nicotine withdrawal. We annotated all genome-wide significant SNPs for their functional potential. First, we …

Association Between Reductions Of Number Of Cigarettes Smoked Per Day And Mortality Among Older Adults In The United States, Maki Inoue-Choi, Patricia Hartge, Yikyung Park, Christian C Abnet, Neal D Freedman

2010-2019 OA Pubs

Many smokers do not quit but instead reduce the number of cigarettes they smoke per day (CPD) over their lifetime. Yet the associations of such changes in CPD with health risks are unclear. We examined the association of changes in CPD with subsequent death in the period 2004-2011 among 253,947 participants of the National Institutes of Health-AARP Diet and Health Study. Using a questionnaire assessing responders' history of smoking cigarettes, we identified cigarette smokers who quit, decreased, maintained, or increased their CPD between ages 25-29 and 50-59 years. Hazard ratios and 95% confidence intervals were obtained from multivariable adjusted Cox …

A person's lipid profile is influenced by genetic variants and alcohol consumption, but the contribution of interactions between these exposures has not been studied. We therefore incorporated gene-alcohol interactions into a multiancestry genome-wide association study of levels of high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides. We included 45 studies in stage 1 (genome-wide discovery) and 66 studies in stage 2 (focused follow-up), for a total of 394,584 individuals from 5 ancestry groups. Analyses covered the period July 2014-November 2017. Genetic main effects and interaction effects were jointly assessed by means of a 2-degrees-of-freedom (df) test, and a 1-df test …
