Evaluation of the Sustainability of an Intervention to Increase HIV Testing

BACKGROUND Sustainability—the routinization and institutionalization of processes that improve the quality of healthcare—is difficult to achieve and not often studied. OBJECTIVE To evaluate the sustainability of increased rates of HIV testing after implementation of a multi-component intervention in two Veterans Health Administration healthcare systems. DESIGN Quasi-experimental implementation study in which the effect of transferring responsibility to conduct the provider education component of the intervention from research to operational staff was assessed. PATIENTS Persons receiving healthcare between 2005 and 2006 (intervention year) and 2006 and 2007 (sustainability year). MEASUREMENTS Monthly HIV testing rate, stratified by frequency of clinic visits RESULTS The monthly adjusted testing rate increased from 2% at baseline to 6% at the end intervention year and then declined reaching 4% at the end of the sustainability year. However, the stratified, visit-specific testing rate for persons newly exposed to the intervention (i.e., having their first through third visits during the study period) increased throughout the intervention and sustainability years. Increases in the proportion of visits by patients who remained untested despite multiple, prior exposures to the intervention accounted for the aggregate attenuation of testing during the sustainability year. Overall, the percentage of patients who received an HIV test in the sustainability year was 11.6%, in the intervention year 11.1%, and in the pre-intervention year 5.0% CONCLUSIONS Provider education combined with informatics and organizational support had a sustainable effect on HIV testing rates. The effect was most pronounced during patients' early contacts with the healthcare system.Health Services Research & Development Service (SDP 06–001

Programa didáctico para fomentar la vivencia eucarística de los estudiantes de la I. E. Toribio Casanova de la Provincia de Cutervo, 2021

La Eucaristía es el centro y culmen de la vida cristiana, en este Sacramento la persona es capaz de unirse con Jesucristo; ante ello es urgente fortalecer la vivencia del sacramento en el cristiano en acciones concretas como son la Misa y la fiesta del Corpus Christi. Por consiguiente, la presente investigación de enfoque cuantitativo y paradigma positivista, a nivel descriptivo, en la investigación se tuvo como objetivo: “Elaborar una propuesta didáctica, para fortalecer la vivencia Eucarística de los estudiantes de la I.E. Toribio Casanova de la Provincia de Cutervo, 2021”, y como objetivos específicos Diagnosticar la vivencia de las acciones en relación a la vida Eucarística y Establecer acciones didácticas que ayude a fomentar la vivencia Eucarística de los estudiantes; para ello se realizó, validó y aplicó una encuesta a 250 estudiantes, la cual media la vivencia del sacramento. Después de aplicarse el test se recogió y analizó los resultados de manera estadística, lo cual evidenció la falta de vivencia del Sacramento en acciones de preparación, oración, adoración, agradecimiento, entre otros; siendo este resultado un porcentaje alto de estudiantes entre el 40% en algunas cuestiones y en otras con una tendencia más alta, todo ello resulta ser preocupante porque son adolescentes que están afianzando su dimensión espiritual. Finalmente se desarrollaron acciones pedagógicas para mejorar la vivencia de los estudiantes en relación a la eucaristía

Highly efficient perovskite solar cells with tunable structural color

The performance of perovskite solar cells has been progressing over the past few years and efficiency is likely to continue to increase. However, a negative aspect for the integration of perovskite solar cells in the built environment is that the color gamut available in these materials is very limited and does not cover the green-to-blue region of the visible spectrum, which has been a big selling point for organic photovoltaics. Here, we integrate a porous photonic crystal (PC) scaffold within the photoactive layer of an opaque perovskite solar cell following a bottom-up approach employing inexpensive and scalable liquid processing techniques. The photovoltaic devices presented herein show high efficiency with tunable color across the visible spectrum. This now imbues the perovskite solar cells with highly desirable properties for cladding in the built environment and encourages design of sustainable colorful buildings and iridescent electric vehicles as future power generation sources.European Union FP7/ 2007-2013Ministerio de Economía y Competitividad MAT2011-23593Junta de Andalucía FQM524

Electron injection and scaffold effects in perovskite solar cells

In spite of the impressive efficiencies reported for perovskite solar cells (PSCs), key aspects of their working principles, such as electron injection at the contacts or the suitability of the utilization of a specific scaffold layer, are not yet fully understood. Increasingly complex scaffolds attained by the sequential deposition of TiO2 and SiO2 mesoporous layers onto transparent conducting substrates are used to perform a systematic characterization of both the injection process at the electron selective contact and the scaffold effect in PSCs. By forcing multiple electron injection processes at a controlled sequence of perovskite–TiO2 interfaces before extraction, interfacial injection effects are magnified and hence characterized in detail. An anomalous injection behavior is observed, the fingerprint of which is the presence of significant inductive loops in the impedance spectra with a magnitude that correlates with the number of interfaces in the scaffold. Analysis of the resistive and capacitive behavior of the impedance spectra indicates that the scaffolds could hinder ion migration, with positive consequences such as lowering the recombination rate and implications for the current–potential curve hysteresis. Our results suggest that an appropriate balance between these advantageous effects and the unavoidable charge transport resistive losses introduced by the scaffolds will help in the optimization of PSC performance.Unión Europea 7PM / 2007-2013Unión Europea ERC 307081 (POLIGHT)Ministerio de Economía y Competitividad de España MAT2014-54852-RMinisterio de Economía y Competitividad de España MAT2015-70611-ER

Diagnóstico de parásitos gastrointestinales en bovinos del departamento de Boyacá, Colombia

Parasitic diseases are considered to be one of the most prevalent pathologies worldwide. They are characterized as one of the most critical sanitary problems in cattle, causing a decrease in the productive capacity of parasitized animals, which translates into economic losses. Intestinal parasitism in cattle is caused by protozoa and helminths, and its manifestation is generally multi-etiological. Clinical signs in gastrointestinal parasitism may vary depending on parasite load, parasite species, and host immunity. This research aimed to determine the prevalence of the main parasitic families affecting cattle in the central province of the department of Boyacá. A cross-sectional study with simple random sampling was carried out, where 716 fecal samples were taken and processed using a modified Ritchie technique. An overall prevalence of 95,6% was determined, and the most prevalent families were Trichostrongylidae, Eimeriidae, Taeniidae, and Trichuridae. The age showed no significant statistical association with most of the parasitic families, except for the Strongyloididae family. The breeds showed a correlation with the Trichostrongylidae, Eimeriidae, Strongylidae, Chabertiidae, and Taeniidae families. The results show the high prevalence of GIP (gastrointestinal parasites) in cattle of the central province of the department of Boyacá.Las enfermedades parasitarias son consideradas como una de las patologías más prevalentes alrededor del mundo.

El parasitismo gastrointestinal en bovinos es causado por protozoos y helmintos, y generalmente su presentación es multietiológica. Los signos clínicos en el parasitismo gastrointestinal pueden variar dependiendo de la carga parasitaria, la especie parasitaria  y la inmunidad del huésped. El objetivo de esta investigación fue determinar la prevalencia de las principales familias parasitarias que afectan a los bovinos de la provincia central del departamento de Boyacá. Se realizó un estudio de corte transversal con muestreo aleatorio simple, en el cual se tomaron 716 muestras de materia fecal que fueron procesadas mediante la técnica de Ritchie modificada. Se determinó una prevalencia general de 95,6 %, en donde las familias más prevalentes fueron Trichostrongylidae, Eimeriidae, Taeniidae y Trichuridae. La edad no presentó asociación estadística significativa con la mayoría de las familias parasitarias, a excepción de la familia Strongyloididae. La raza mostró asociación con las familias Trichostrongylidae, Eimeriidae, Strongylidae, Chabertiidae y Taeniidae. Los resultados muestran una alta prevalencia de PGI (parásitos gastrointestinales) en la provincia central de Boyacá
