PERCEPCION SUBJETIVA DE ADAPTACION AL TURNO LABORAL EN TRABAJADORES CON ULCERA PEPTICA
Romero Madero,Jesús;
Revista Habanera de Ciencias M??dicas , 2007,
Abstract: a mathematical-statistical model was calculated by means of the multivariade discriminant analysis (p <0,05) to a sample of 76 workers, to differentiate the exposed workers and not to night shift work, basing us on the expression of the risk factors related with the gastroduodenal peptic ulcer and the subjetive perception of adaptation to the type of shift work was determinated in comparative form betwen groups. the study design was analytic of traverse court. the instruments applied to explore the factors of risk were: factors of individuality, personality, symptomatic scale of stress, exploration of labor fatigue and labor situation. the analogical-visual scale was applied to evaluate the subjetive perception of adaptation to shift work. the calculated discriminant function had a capacity of prognostic of 86,8% and the subjetive perception of adaptation to shift work was bad in 43,4 % of the sample without any significant differencies betwen groups. this result can constitute a first step in the strategy of prevention of this affection in our workers and keep alert about impact of psicological variables as subjetive perception of adaptation to shift work in that desease.
FACTORES DE RIESGO RELACIONADOS CON LA ULCERA PEPTICA GASTRODUODENAL Y EXPOSICION A NOCTURNIDAD
Romero Madero,Jesús;
Revista Habanera de Ciencias M??dicas , 2007,
Abstract: the risk factors related with the gastroduodenal peptic ulcer were compared in a sample of 76 workers divided in two groups: exposed and not to nigth shift work as well as among the subgrups of the first one. the study design was analytic type of traverse court with a not probabilistic sampling. the test chi-square was applied (alfa>=95%) for the significance of the differences among the groups. the exposed group to night shift work and the subgrup with rotative quick changes shift work they presented bigger incidence of the risk factors for that desease. the night shift work and specifically the workers with rotative quick chances had more appropriated conditions for happening of the gastroduodenal peptic ulcer because the frequency of appearance of the risk factors and they presuppose bigger interaction with circadian rhythm dysruptions.

Abstract: Se compararon los factores de riesgo relacionados con la úlcera péptica gastroduodenal en una muestra de 76 trabajadores, divididos en dos grupos: expuestos y no a nocturnidad; así como entre los subgrupos del primero. El dise o de estudio fue tipo analítico de corte transversal con un muestreo no probabilístico. Se aplicó la prueba Chi cuadrado (alfa > o = 95%) para la significación de las diferencias entre los grupos. E l grupo expuesto a nocturnidad y el subgrupo: rotativo de cambios rápidos, presentaron mayor incidencia de los factores de riesgo de la UPGD. Los turnos de trabajo nocturnos y específicamente los trabajadores con rotación rápida, tuvieron condiciones más propicias para la génesis de la UPGD, por la frecuencia de aparición de los factores de riesgo y presuponen mayor interacción con los trastornos en los ritmos circadianos de sus trabajadores.

Abstract: Se calculó un modelo matemático-estadístico por medio del análisis multivariado discriminante a una muestra de 76 trabajadores, para diferenciar los trabajadores expuestos y no expuestos a nocturnidad; nos basamos en la expresión de los factores de riesgo relacionados con la úlcera péptica gastroduodenal (p<0,05) y se determinó de forma comparativa entre los grupos la percepción subjetiva de adaptación al turno de trabajo . El dise o de estudio fue analítico de corte transversal. Los instrumentos aplicados para explorar los factores de riesgo fueron: Factores de individualidad, Personalidad, Escala Sintomática de Estrés, Exploración de Fatiga Laboral y Situación Laboral .Se aplicó la Escala Analógico-Visual como instrumento de evaluación de la percepción subjetiva de adaptación al turno de trabajo. La función discriminante calculada tuvo una capacidad de pronóstico de 86,8% y la percepción subjetiva de adaptación al turno de trabajo fue mala en 43,4 % de la muestra, sin diferencias significativas entre los grupos. La capacidad discriminante de este modelo puede constituir un primer paso en la estrategia de prevención de esta afección en nuestros trabajadores y alertarnos acerca del valor que pueden tener variables psicológicas como la percepción subjetiva de adaptación al turno de trabajo en la misma.

Abstract: the academic performance measured each year by simce shows that results differ depending on various social attributes. most studies on this topic show the relevance of social class. this research extends the analysis of class to another form of social stratification such as gender, as both categories have an impact on students' skills and educational abilities which are formally included in the educational field. we conclude that, in the sites surveyed, inequality of educational privileges has perpetuated under these two variables, evidencing an educational system which discriminates primarily against girls in conditions of greater social vulnerability.

Abstract: Los rendimientos escolares que mide cada a o el SIMCE, muestran resultados que se diferencian en función de diversos atributos sociales. La mayor parte de los estudios referidos a este tema, evidencian resultados estructurados en función de la clase social. La presente investigación amplía el análisis de clase a una forma adicional de estratificación social, como el género, pues ambas categorías poseen un impacto en las competencias y habilidades educacionales de los estudiantes que se encuentran ya incluidos formalmente al campo educativo. Se concluye que, en las localidades investigadas, se ha perpetuado la desigualdad de los privilegios educativos en virtud de estas dos variables, operando de este modo un sistema educacional en el cual se discrimina negativamente principalmente a ni as en mayores condiciones de vulnerabilidad social. Os rendimentos escolares obtidos anualmente, por meio do SIMCE, revelam que os resultados diferem-se entre si em raz o de vários atributos sociais. A maioria dos estudos relacionados a este tema evidencia resultados estruturados consoante a classe social. Esta pesquisa estende a análise de classe para uma forma adicional de estratifica o social como gênero, pois as duas categorias têm um impacto sobre competências e habilidades educacionais dos estudantes incluídos no sistema educacional. Concluí-se que, nas localidades pesquisadas, perpetuou-se a desigualdade de privilégios educacionais no ambito dessas duas variáveis, fazendo com que o sistema educacional discrimine as estudantes em condi es de maior vulnerabilidade social, principalmente.

Abstract: La utilización de sangre de cordón como fuente de precursores hematológicos se remonta a 1983 cuando Boyse apuntó el potencial en progenitores existente en la sangre de cordón, realizándose un a o más tarde las primeras experiencias sobre modelos murinos. Tuvieron que pasar más de cinco a os para que Gluckman realizara la primera experiencia en humanos. Un ni o afecto de anemia de Fanconi fue trasplantado con progenitores de sangre de cordón umbilical de su hermana HLA idéntica, realizándose todos los estudios de compatibilidad intraútero. Actualmente, veinte a os más tarde, el paciente se encuentra libre de enfermedad y con la hematopoyesis del donante, demostrándose así la capacidad de persistencia del injerto a largo plazo.

Abstract: Proponer conclusiones a un encuentro que, aún respetando a grandes rasgos la convocatoria inicial, prolifera en objetos y enfoques y hace dialogar tradiciones de investigación que, más allá de indudables inspiraciones comunes, han crecido en terrenos diversos y encontrado limitaciones, obstáculos o incitaciones diferentes, no es tarea fácil. Mi intención se reducirá por lo tanto a intentar trazar algunas problemáticas comunes y pido disculpas de antemano si este gesto no da cuenta de la rique...

Abstract: En los últimos a os, la interrogación sobre las técnicas y los procedimientos que permiten a una comunidad dar por válidos los enunciados que produce y considerarlos, por lo tanto, verdaderos , ha conducido a una profunda renovación de varias disciplinas clásicas . Baste recordar las discusiones abiertas sobre la relación – negada o afirmada según los casos – entre figuras del discurso y pruebas factuales en los estudios consagrados a la retórica clásica , o los trabajos de la nueva histor...

Abstract: aim: in the last years it has spread minimally invasive therapeutic for the treatment of pyeloureteral junction obstruction in children. some of them have got poor outcomes in 4-year-old minor children. we show our experience in the retrograde dilatation with balloon of high pressure in infants. methods: it's a retrospective study of 16 infants treated in our hospital. the average follow-up after the intervention is 27.4±10.0 months. the diagnostic protocol included abdominal ultrasound, cystogram and diuretic renography. the treatment was realized by endourology retrograde balloon dilatation under fluoroscopy. the balloons were in all the cases semicompliant, with a profile of 5 mm, 6 mm ó 7 mm. after the expansion there was placed stents type double j with profile and length depending on the weight of the patient. to obtain the results, we do ultrasound scans and diuretic renography at least 1 year after the intervention. results: the mean duration of the intervention was 36.4±15.5 minutes. during the intervention, in 2 patients the placement of the stent was not possible. the time of revenue was 48 hours in all the patients except in 1 of them. the analgesic needs were exclusively non steroid antiinflammatorys. the double j stent was withdrawn with cystoscopy. in 3 patients there were postoperatory complications: a migration of the stent, a urinary infection and an urinoma. in 1 patient with worsening of hydronephrosis was needed of pyeloplasty. in the controls the disappearance of the hydronephrosis was observed in all the cases, eliminating likewise the expansion of the renal calyces. the diuretic renography improved in all babies, being the boss of the curve normal in 14 cases and semi obstructively in 2. the mean time of elimination was 9.8±2.8 minutes. conclusions: we think that the balloon dilatation of pyeloureteral junction obstruction is a minimally aggressive technique that is possible to realize in infants with good results and scanty complications.
