Factors Associated with Participation in the Oregon Summer Food Program: A Mixed Methods Analysis

The Summer Food Service Program (SFSP) was established to ensure children eligible for the National School Lunch Program (NSLP) continue to receive meals outside of the school year. However, participation in SFSP is relatively low (2.8 million annually) when compared with NSLP participation (30.4 million annually), suggesting that challenges exist in reaching children. Using a mixed methods approach, this study explored factors associated with SFSP participation. A secondary data analysis of the Oregon SFSP identified factors associated with SFSP participation at the Oregon SFSP-, sponsor-, and site-levels. Semi-structured interviews with SFSP sponsors explored barriers and facilitators to SFSP participation. Results showed increases in the total number of meals served as well as number of sponsors and sites for the Oregon SFSP over the study period. Sponsor average daily participation (ADP) demonstrated a significant decrease over the study period. Sponsors that offered more meal types, greater number of activities, and were school districts had a higher ADP. Results from interviews showed themes of organizational characteristics, site environment, and meal logistics. Findings suggest that strengthening existing sites and tailoring the current SFSP model to allow successful expansion of the program to new sites may have the greatest impact on increasing average daily participation and improve the operational sustainability of the SFSP

Short term dynamics of the sputum microbiome among COPD patients.

Chronic obstructive pulmonary disease (COPD) is an inflammatory disorder characterized by incompletely reversible airflow obstruction. The complexity of the lung microbial community in COPD patients has been highlighted in recent years. Evidence suggests that transplantation, medications, age, and disease severity influence microbial community membership. However, the dynamics of the lung microbiome in stable COPD patients remain poorly understood. In this study, we completed a longitudinal 16S ribosomal RNA survey of the lung microbiome on replicate sputum samples collected from 4 former smokers with COPD (Stage 2) within a 2-day time period. Samples from each individual over the two-day period were similar based on α-diversity, principle component analysis and taxonomy at the phyla and genera level. Sputum samples from COPD patients were also collected between 2-9 months of follow-up. Data suggest an increased variability of the sputum microbiota when comparing samples collected ≤ 3 months compared to those collected ≥ 4 months; however, no statistically significant shifts in the abundance (\u3e2-fold) of taxa between the two time points was observed. Bacterial composition and the number of operational taxonomic units (OTUs) remained similar over time. Results from this study suggest that the sputum microbiome is relatively stable in clinically stable COPD patients (Stage 2). This study furthers our understanding of the dynamics of the lung microbiome in COPD patients

Immunisation with purified Coxiella burnetii phase I lipopolysaccharide confers partial protection in mice independently of co-administered adenovirus vectored vaccines

Q fever is a highly infectious zoonosis caused by the Gram-negative bacterium Coxiella burnetii. The worldwide distribution of Q fever suggests a need for vaccines that are more efficacious, affordable, and does not induce severe adverse reactions in vaccine recipients with pre-existing immunity against Q fever. Potential Q fever vaccine antigens include lipopolysaccharide (LPS) and several C. burnetii surface proteins. Antibodies elicited by purified C. burnetii lipopolysaccharide (LPS) correlate with protection against Q fever, while antigens encoded by adenoviral vectored vaccines can induce cellular immune responses which aid clearing of intracellular pathogens. In the present study, the immunogenicity and the protection induced by adenoviral vectored constructs formulated with the addition of LPS were assessed. Multiple vaccine constructs encoding single or fusion antigens from C. burnetii were synthesised. The adenoviral vectored vaccine constructs alone elicited strong cellular immunity, but this response was not correlative with protection in mice. However, vaccination with LPS was significantly associated with lower weight loss post-bacterial challenge independent of co-administration with adenoviral vaccine constructs, supporting further vaccine development based on LPS

A principal factor analysis to characterize agricultural exposures among Nebraska veterans

Agricultural workers are at an increased risk of developing chronic respiratory disorders. Accurate estimation of long-term agricultural exposures based on questionnaires has been used to improve the validity of epidemiologic investigations and subsequent evaluation of the association between agricultural exposures and chronic diseases. Our aim was to use principal factor analysis (PFA) to distill exposure data into essential variables characterizing long-term agricultural exposures. This is a crosssectional study of veterans between the ages of 40 and 80 years and who worked on a farm for ≥ 2 years. Participant characteristics were: 98.1% were white males with a mean age 65 ± 8 (SD) years and 39.8% had chronic obstructive pulmonary disease. The final model included four factors and explained 16.6% of the variance in the exposure data. Factor 1 was a heterogeneous factor; however, Factor 2 was exclusively composed of exposure to livestock such as hogs, dairy and poultry. Factor 3 included exposures from jobs on or off the farm such as wood dust, mineral dust, asbestos and spray paint. Crop exposure loaded exclusively in Factor 4 and included lifetime hours of exposure and maximum number of acres farmed in the participants’ lifetime. The factors in the final model were interpretable and consistent with farming practices

Metrics to Measure Website Effectiveness

This paper seeks to improve websites by analyzing the relationship between measurable elements of a website and the number of page views. The effectiveness of a website is the ability to drive interest in the content provided on the site. Websites perform an important role of communicating the goals of the organization with potential consumers for the organization. The analysis of the metrics chosen, including bounce rate, time on site, number of visitors, and number of entrances through web pages, utilizes data from the Poetry Foundation, a nonprofit organization whose purpose is to increase the prevalence of poetry, to provide an analysis utilizing real data to determine whether the predictions made in this paper are correct, and how the variables examined may be maximized to find an optimal effectiveness level. The end result is a determination of the most important metrics to watch in order to maximize the number of visitors to the website.B.S. (Bachelor of Science
