Bacteriemia asociada a catéter epicutáneo en la unidad de cuidado intensivo neonatal de la Fundación Cardioinfantil

La bacteriemia asociada a catéter afecta a pacientes en las unidades de cuidado intensivo con una alta morbilidad, mortalidad y aumento de los costos al sistema de salud. Los recién nacidos son la población de más alto riesgo por el mayor uso de catéteres centrales. Objetivo: Caracterizar factores de riesgo para bacteriemia asociada a catéter en la Unidad de Cuidado Intensivo Neonatal de la Fundación Cardioinfantil entre 2005 - 2010 Materiales y método: Estudio descriptivo de corte transversal, incluyó todos los recién nacidos con diagnostico de bacteriemia asociada a catéter. Se analizó la información utilizando frecuencias y medidas de tendencia central. Resultados: Se encontraron 50 pacientes con diagnostico de bacteriemia asociada a catéter. 50% de género masculino, 52% con edad gestacional al nacimiento menor a 36 semanas y 24% con peso menor a 1500 gramos al momento de la inserción del catéter. La edad fue de 24.2 días al momento de la inserción del catéter. En el 66% de los pacientes el sitio de inserción fue el miembro superior, siendo el Sthaphylococcus Epidermidis el germen con el 50% de las bacteriemias. Conclusión: La bacteriemia asociada a catéter afecta paciente prematuros, de bajo peso sin diferencias en genero. La manipulación de dichos dispositivos, el sitio de inserción, el uso previo de antibióticos, la duración del catéter y el uso de nutrición parenteral son factores que están asociados al mayor riesgo de infección. Siendo el Staphylococcus Epidermidis el germen mas frecuente.

Teleconsultation in sexual and reproductive health for young adults through mobile devices: Experience in Colombia

Background: Sexual risk behaviors associated with poor information on sexuality have contributed to major public health problems in the area of sexual and reproductive health in teenagers and young adults in Colombia. Objective: To measure the perception of changes in sexual and reproductive risk behavior after the use of a teleconsultation service via mobile devices in a sample of young adults. Methods: A before and after observational study was designed, where a mobile application to inquire about sexual and reproductive health was developed. The perception of changes in sexual and reproductive health risk behaviors in a sample of young adults after the use of the application was measured using the validated survey “Family Health International (FHI) – Behavioral Surveillance Survey (BSS) – Survey for Adults between 15 to 40 Years”. Non-probabilistic convenience recruitment was undertaken through the study´s web page. Participants answered the survey online before and after the use of the mobile application for a six month period (intervention). For the inferential analysis, data was divided into three groups (dichotomous data, discrete quantitative data, and ordinal data), to compare the results of the questions between the first and the second survey. For all tests, a confidence interval of 95% was established. For dichotomous data, the Chi-squared test was used. For quantitative data, we used the Student’s t-test, and for ordinal data, the Mann-Whitney-Wilcoxon test. Results: A total of 257 subjects were registered in the study and met the selection criteria. The pre-intervention survey was answered by 232 subjects, and 127 completely answered the post-intervention survey, of which 54.3% did not use the application, leaving an effective population of 58 subjects for analysis. 53% (n=31) were female, and 47% (n=27) were male. The mean age was 21 years, ranging between 18 and 40 years. The differences between the answers on the first and the second survey were not statistically significant. The main risk behaviors identified in the population were homosexual relations, non-use of condoms, sexual relations with non-regular and commercial partners, the use of psychoactive substances, and ignorance about the symptoms of sexually transmitted diseases and HIV transmission. Conclusions: Although there were no differences between the pre- and post-intervention results, the study revealed different risk behaviors among the participating subjects. These findings highlight the importance of promoting educational strategies on this matter and the importance of providing patients with easily accessible tools with reliable health information.

Preliminary factorial structure of the O’Kelly Women’s Belief Scales in Mexican population

A Back-translated Mexican version of the Austra- lian o’Kelly Women’s Belief scales was given to a sample of 363 women born and living in Mexico. A factor analysis with a varimax rotation with cu- toff eigenvalues of 3 showed that 36 out of the 92 items originally developed in the Australian study accounted for 40.138% of the variance, and could be ultimately grouped into two factors: one “ra- tionality” factor, with a total of 14 items, and one “Irrationality” factor with a total of 22 items, and with a very low Pearson’s rs (.119) between them. these results support the equivalency of the Mexi- can version to the original instrument used to iden- tify the presence of the reBt’s absolutistic, rigid beliefs about traditional feminine roles in women.
