Métodos Se eligió una cohorte retrospectiva en pacientes que iniciaron DP dentro del periodo enero de 2002-diciembre de 2011 en el Hospital Nacional Guillermo Almenara Irigoyen. Se describieron los tiempos de seguimiento según la fecha de inicio de DP y la primera peritonitis u otros eventos (paso a hemodiálisis, trasplante, muerte o abandono). Las variables fueron evaluadas según su tipo, utilizando estadística descriptiva e inferencial. Resultados El análisis incluyó a 218 pacientes con una media de edad de 54 años ± 16. El principal lugar donde se realiza el procedimiento de DP es el dormitorio (77,3%), en su mayoría se encuentra limpio (54,3%), ordenado (71,3%) y despejado (61,8%). Los insumos para el procedimiento se almacenan bajo techo (95,7%) y el mismo paciente ejecuta el tratamiento en la mayoría de los casos (73,1%). La incidencia encontrada fue de 0,17 episodios/paciente-año. La media del tiempo de seguimiento fue de 975 días ± 750. De acuerdo al análisis realizado, no se encontraron resultados significativos que muestren la relación entre las variables de vivienda y el desarrollo de la primera peritonitis. Conclusión No se encontró asociación entre las condiciones de vivienda y el desarrollo de peritonitis en pacientes en tratamiento de DP. Es necesario evaluar y mejorar el programa de visitas domiciliarias.

Introducción: Se describe que las características de la vivienda son un factor importante para llevar a cabo adecuadamente el tratamiento de diálisis peritoneal, sin embargo, no se conoce la real relación entre las características de la vivienda y el desarrollo de la peritonitis. Métodos: Se realizó una cohorte retrospectiva que incluyó a todos los pacientes mayores de 18 años de edad que iniciaron el tratamiento de diálisis peritoneal dentro del periodo enero 2002 - diciembre 2011 en el Hospital Nacional Guillermo Almenara Irigoyen. Se describió los tiempos de seguimiento según la fecha de inicio de DP y la primera peritonitis u otros eventos (paso a hemodiálisis, trasplante, muerte o abandono). Las variables fueron evaluadas según su tipo, utilizando estadística descriptiva e inferencial. Resultados: El análisis incluyó a 218 pacientes con una media de edad de 54 años ± 16. El principal lugar donde se realiza el procedimiento de diálisis peritoneal es el dormitorio (77,3%), en su mayoría se encuentra limpio (54,3%), ordenado (71,3%) y despejado (61,8%). Los insumos para el procedimiento se almacenan bajo techo (95,7%) y el mismo paciente ejecuta el tratamiento en la mayoría de los casos (73,1%).

De acuerdo al análisis realizado no se encontró resultados significativos que muestren la relación entre las variables de vivienda y el desarrollo de la primera peritonitis. Conclusión: No se encontró asociación entre las condiciones de vivienda y el desarrollo de peritonitis en pacientes en tratamiento de diálisis peritoneal.

However, the actual situation is that it doesn’t know the real relationship between the characteristics of housing and the development of peritonitis. Methods: A retrospective cohort was made including all patients over 18 years who started PD between the period January 2002 and December 2011 at the Hospital National Guillermo Almenara Irigoyen. The follow-up times was described as the beginning date of use DP and the first peritonitis or other events (hemodialysis, transplant, death or abandonment). The variables were evaluated according to their type using descriptive and inferential statistic. Results: The analysis included 218 patients with a mean age of 54 years ± 16. The main place where the patients did the procedure of peritoneal dialysis is the bedroom (77,3%), most of it is clean (54,3%), organized (71,3%) and clear (61,8%). The inputs for the procedure are stored indoors (95,7%) and the person who executes the procedure is the patient in most cases (73,1%). The observed incidence was 0,17 episodes/patient-year. The mean follow-up time was 975 days ± 750. No significant results were found between the housing conditions and the development of the first peritonitis in patients who are treated by peritoneal dialysis. Conclusion: No association was found between the housing conditions and the development of the first peritonitis. It is necessary to evaluated and improve the home visit program in order to obtain better information of housing condition.

The following thesis is concerned with the ways in which perceptions of crime and disease shaped knowledge about urban decline and structured demands for urban renewal projects in Richmond, Virginia between 1953 and 1964. By looking at the city's renters, landlords, public health officials, and local politicians, this thesis contains three arguments: first, advocates diagnosed economic decline through medical and criminal categories; secondly, if urban renewal's existential purpose was to correct the environmental determinants of social pathology, then the contest between renewal advocates and opponents defined an economically-delimited solution; lastly, renewal contained the basis for a strengthened post-war, post-Jim Crow Southern state a state whose most important prerogative was not the maintenance of race relations, but the protection of property and capital. This mode, the capitalist-interventionist mode of state formation is an alternative archetype for historians of the post-war South, implicates capitalist impulses as an accomplice in structuring racial domination, and not simply an extension of Southern barbarity and Jim Crow. The first chapter interrogates the ways in which renewal supporters appropriated knowledge about crime and disease to address urban decline, both its supposed causes and possible solutions. The second chapter focuses on how renewal advocates created competing market evaluations of pathology in Richmond's Seventeenth-Street Bottom, as they cleared the supposed slum to build the new city jail. The conclusion poses suggestions for further historical research on the categories of crime and disease and the relevance of Jim Crow. / History

Crossbred pigs 3 to 4 weeks of age were randomly assigned from outcome groups based on weight and sex to one of four dietary treatments either with or without added soybean oil or hulls. Nursery air quality was evaluated by measuring the concentrations of ammonia, carbon dioxide, settled dust, suspended particle size, and by microbiologically culturing air samples. Weekly performance data was also collected. ADG was unaffected by dietary treatment. ADFI was increased when soybean hulls were added to the ration with the difference being significant in trials 1 and 2 and over-all. Adding soybean oil to the ration produced slightly lower feed intakes over all trials but was not significant. Rations with added soybean oil reduced F/G, whereas, the addition of soybean hulls increased F/G for over-all trials. The response to soybean oil was less when soybean hulls were added. A comparison of rations 1 and 4 showed only slight differences in ADG, ADFI and F/G. The addition of soybean oil resulted in a 47% reduction in settled dust for trials 1 and 2 combined, and a 45% reduction for trial 3. Mean bacterial colony counts for each week and over-all for trial 3 were lower when soybean oil was added to the ration. Ammonia and carbon dioxide concentrations were not affected by dietary treatment. From the results of this experiment, the addition of soybean oil to starter diets improved nursery air quality and performance in some cases, however, gas concentrations were not different. / Master of Science
