Algorithms, SAS code, and documentation supporting the Johns Hopkins Overuse Index
No full textAlgorithms, SAS code, and documentation supporting the Johns Hopkins Overuse Index. We used the IBM (formerly Truven) MarketScan® data to generate the Johns Hopkins Overuse Index that we had previously developed using Medicare claims data. These resources have supported our work in understanding regional overuse of healthcare resources across time, for examining possible drivers of overuse, and for evaluating the impact of the Maryland Global Budget Revenue waiver on overuse in the State
Data associated with publication "Contributions to Composite Conductivity and Seebeck Coefficient in Commercial Bi2Te3 – Conjugated Polymer Composites"
No full textWe demonstrated the use of the as-received conjugated polymer P3HT (poly (3-hexylthiophene-2,5 diyl) doped with F4TCNQ (2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane) as a matrix for forming a composite with as-received, commercially available p-type Bi2Te3 powder. The optimized formulation exhibits a power factor of up to 5.3 uW K-2 m-1, about nine times higher than the highest power factor we achieved from mixtures of only P3HT and F4TCNQ. The Bi2Te3 was responsible for increases in both Seebeck coefficient and electrical conductivity. P3HT, with higher hole mobility, was superior to PQT12 (poly(bisdodecylquaterthiophene), and F4TCNQ was at least as good as FeCl3, for matrix and dopant, respectively, for this purpose. The power factor obtained is about 40% of that reportedly obtained from synthesized Bi2Te3 nanowires in FeCl3-doped P3HT. We calculated the expected contributions of bulk Bi2Te3 to the composite conductivity and then examined the resistance caused by interfaces on four different size distributions of Bi2Te3 particles, as well as a solid macroscopic ingot. A nonlinear I-V relationship was found for the doped P3HT-ingot bilayer. While our doped conjugated polymer system made only from commercial-grade components was shown to support the extraction of thermoelectric performance by a commonly used inorganic semiconductor, our results also suggest that an advantage of the smallest Bi2Te3 domains, including nanowires, may arise from their having less interfacial resistance than larger Bi2Te3 particles and pieces
The Policy and Science for Health, Agriculture and Nutrition (PoSHAN) Annual Survey Datasets 2013-2016
No full textThe Feed the Future Innovation Lab for Nutrition, with funding from the USAID, conducted a series of four annual surveys – The Policy and Science for Health, Agriculture and Nutrition (PoSHAN) Surveys – in Nepal from 2013-2016. The aim of the surveys was to assess nutritional status, diet and morbidity of preschool aged children and their mothers, and recently married, nulliparous women, and household food security, agricultural practices, participation in services and programs, among other factors, and examine associations between agricultural practices and food security, nutritional status, diet and health. The broader goal was guide policy and program interventions that may influence household food security, poverty, and the diets, health and nutrition of pre-school children and their mothers.
The PoSHAN surveys were conducted in a total of 21 sub-district units or Village Development Committees (VDCs), each in a unique district. The VDCs in PoSHAN form a nationally representative sample, stratified by the agroecological zones of Mountains, Hills and Terai (plains) with each zone containing 7 VDCs. Further, each VDC consisted of a set of 3 wards, adding up to a total of 63 wards in the full sample. The PoSHAN surveys were conducted in the same season and site every year, with seasonal (sentinel) surveys conducted every 3 months during the first two years of the survey. Eligible households included in the survey consisted of households that either had at least one child under 5 years or a newly-married woman (married within the past 2 years).
The annual surveys were conducted in all 21 VDCs with data collected using a total of 10 types of forms that collected information at the community, market, household and individual levels. The seasonal surveys were conducted in 3 of the 21 VDCs, one from each zone, that collected data on up to 7 forms with the focus of collecting data on household’s seasonal agricultural production. The datasets thus generated from these surveys make up a total of 4 annual surveys and 4 seasonal surveys.
This collection contains the cross-sectional dataset for the annual surveys conducted from 2013 through 2016. For more information visit: http://pubs.sciepub.com/jfs/6/2/5/. (Link to Seasonal Surveys.)
Data files are formatted for STATA, and include MS Excel and CSV formats. Data specificity is limited to the regional district level to maintain participants' anonymity for public access.

Meteorological station data associated with publication Stettz et al. (2019) Estimating variability in downwelling surface shortwave radiation in a tropical highland environment. PLOS ONE.
No full textThe data included in these files are daily maximum temperature, daily minimum temperature, and daily average incoming solar radiation for four sites in the Blue Nile Highlands of Ethiopia. They were used to calibrate statistical models of solar radiation as a function of diurnal temperature range and to evaluate solar radiation estimates from existing meteorological reanalysis systems. The purpose is to obtain estimates of daily solar radiation for areas where measurements are not available, as many meteorological data sets do not include information on incoming solar radiation, yet it is a required input for many biophysical models
Data associated with publication “Dopant-Dependent Increase in Seebeck Coefficient and Electrical Conductivity in Blended Polymers with Offset Carrier Energies"
No full textThe strong and counterproductive interrelationship of thermoelectric parameters remains a bottleneck to improving thermoelectric performance, especially in polymer-based materials. In this paper, we decouple the electrical conductivity and Seebeck coefficient, achieving increases in at least one of these two parameters while the other is maintained or slightly increased as well. This is done using an alkylthio-substituted polythiophene (PQTS12) as additive in poly(bisdodecylquaterthiophene) (PQT12) with tetrafluorotetracyanoquinodimethane (F4TCNQ) and nitrosyl tetrafluoroborate (NOBF4) as dopants. The power factor increased two orders of magnitude with the PQTS12 additive at constant doping level. Using a second pair of polymers, poly(2,5-bis(3-dodecylthiophen-2-yl)thieno[3,2-b]thiophene (PBTTTC12) and poly(2,5-bis(3-dodecylthiothiophen-2-yl)thieno[3,2-b]thiophene, (PBTTTSC12), with higher mobilities, we also observed the decoupling of the Seebeck coefficient and electrical conductivity, and achieved higher power factor. Distinguished from recently reported works, these two sets of polymers possess very closely offset carrier energy levels (0.05 ~ 0.07 eV), and the microstructure, assessed using grazing incidence X-ray scattering, and mobility evaluated in field-effect transistors, was not adversely affected by the blending. Experiments, calculations and simulations are consistent with the idea that blending and doping polymers with closely-spaced energy levels and compatible morphologies to promote carrier mobility favors increased power factors
Coded quotations associated with the publication “Men’s perceptions of HIV care engagement at the facility- and provider-levels: experiences in Cote d’Ivoire”
No full textMen in sub-Saharan Africa have lower rates of HIV testing and are less likely to initiate treatment compared to women. Service delivery dimensions are a key factor in facilitating engagement along the HIV treatment continuum for men and women, yet male specific overall perceptions of the service delivery environment have received little attention in West Africa. This study draws on qualitative data collected in Côte d’Ivoire to explore provider-level and structural factors affecting men’s engagement in HIV testing and treatment through interviews and focus group discussions conducted with health workers and men living with HIV (some on ART) or whose HIV status was unknown. The data posted here is a subset of the larger dataset and includes coded quotations (deidentified) relevant to the topic of the manuscript
Data associated with the publication “Nutritional Resilience in Nepal Following the Earthquake of 2015” by Andrew Thorne-Lyman et al.
No full textData posted include six datasets, three for 2014 and three for 2016, at the household, woman and child level respectively for each year. These data come from annual cross-sectional surveys conducted in 7 earthquake affected areas (Village Development Committees’, with 3 wards per VDC). During each round of data collection, all consenting households living in the households meeting eligibility criteria (presence of a child under-5 years of age and/or a reproductive aged woman married in the past 2 years), were enumerated and enrolled. The datasets contain longitudinal linkages that are made in the paper across household, child and women’s data. All datasets are de-identified, no birth dates or geolocations are included. Data files are formatted for STATA, and include MS Excel outputs
Oral health during pregnancy in rural Nepal: a community-based cohort study of practices, periodontal status, and pregnancy outcomes
No full textAnnually, almost three million babies die prior to 28 days of life; the number one cause of these deaths both in high- and low-income settings is complications arising from preterm birth. Therapeutic options for managing preterm birth are generally unavailable for 98% of the almost 15 million preterm babies born each year, and the evidence base for preventative interventions is lacking. One area that has been substantially neglected in developing countries is the role that poor oral health may play raising the likelihood of early spontaneous delivery. There is epidemiologic and microbiologic evidence for an association between maternal periodontal disease and preterm birth, however, causal mechanisms are not fully understood, and results from randomized trials intervening on mothers with periodontal therapies to reduce prematurity have been mixed.
In 2014, we initiated a community-based project to examine this question in a high burden setting with low levels of confounding risk factors. Sarlahi District in southern Nepal fit this description, with high rates of neonatal mortality (28 / 1,000 live births), preterm birth (17%), low birth weight (30%), poor oral health, and low rates of smoking, alcohol use, and chronic diseases. The overall objective of our study was to assess the epidemiologic relationship between periodontal disease and preterm birth and investigate causal mechanisms on the pathway from oral infection to early spontaneous delivery. Our specific aims included the following:
1. Assess the incidence of preterm birth among women with / without periodontitis
2. Examine relationships between causal mechanisms, specifically clinical signs of periodontitis, subgingival biofilm composition, and levels of inflammatory mediators in gingival crevicular fluid and serum
3. Conduct a small pilot trial to estimate the association between adherence to a 0.12% chlorhexidine (non-alcohol) daily mouthrinse and subgingival biofilm composition and levels of inflammatory mediators in gingival crevicular fluid and serum
4. Describe the knowledge, attitudes, and practices related to oral hygiene among women and health professionals in the communit
