ItemMeasuring Health of College Students: Food Security, Diet Quality, and Physical ActivityThanawala, Ninad; Rubinow, Dave; Roga, Zachary; Liou, Harris (2018-04-27)A cross-sectional study was conducted to assess food security, diet quality, and physical activity in college students using a sample of NHANES data on the United States. Prevalence rates of participants achieving full food security, >50 Healthy Eating Index (HEI)-2010 composite score, and >150 minutes moderate or vigorous physical activity (MVPA) per week were measured. Results showed that 28.8% of college students were food insecure, 34.5% had an above-50 HEI score, and 58.2% achieve adequate physical activity per week. In comparison, adults in the general population have lower rates of food insecurity (22.4%), higher rates HEI above 50 (42.2%), and lower rates of adequate physical activity (35.6%), with p<0.05 for all comparisons. These findings suggest that interventions to improve students’ food access and diet quality may be important to implement by institutions of higher education. ItemData from: "Host transcriptional responses following ex vivo re-challenge with Mycobacterium tuberculosis vary with disease status"Yu, Elaine A; John, Serene H; Tablante, Elizabeth C; King, Christine A; Kenneth, John; Russell, David G; Mehta, Saurabh (2017)This dataset supports the following research and conclusions: “The identification of immune correlates that are predictive of disease outcome for tuberculosis remains an ongoing challenge. To address this issue, we evaluated gene expression profiles from peripheral blood mononuclear cells following ex vivo challenge with Mycobacterium tuberculosis, among participants with active TB disease (ATBD, n=10), latent TB infection (LTBI, n=10), and previous active TB disease (after successful treatment; PTBD, n=10), relative to controls (n=10). Differential gene expression profiles were assessed by suppression-subtractive hybridization, dot blot, real-time polymerase chain reaction, and the comparative cycle threshold methods. Comparing ATBD to control samples, greater fold-increases of gene expression were observed for a number of chemotactic factors (CXCL1, CXCL3, IL8, MCP1, MIP1). ATBD was also associated with higher IL1B gene expression, relative to controls. Among LTBI samples, gene expression of several chemotactic factors (CXCL2, CXCL3, IL8) was similarly elevated, compared to individuals with PTBD. Our results demonstrated that samples from participants with ATBD and LTBI have distinct gene expression profiles in response to ex vivo M. tuberculosis infection. These findings indicate the value in further characterizing the peripheral responses to M. tuberculosis challenge as a route to defining immune correlates of disease status or outcome.” ItemThe Division of Nutritional Sciences at Cornell University: A History and Personal ReflectionsNesheim, Malden C.
