Factor analysis of the «Questionnaire for the evaluation of occupational burnout syndrome» in peruvian medical students

 Background: The «Questionnaire for the evaluation of occupational burnout syndrome » («Cuestionario para la evaluación del síndrome de quemarse por el trabajo (CESQT»)» has been proposed to evaluate this syndrome in different populations. However, it has not been used in Latin-American university students. Aim: To evaluate the dimensional structure of CESQT in medical students from Peru. Material and methods: This was an observational, analytical and cross-sectional study, that was performed in a sample of 71 medical students in the last year of their degree (also known as «Medical Internship») in a Public Hospital in Lima, Peru. An exploratory factor analysis (EFA) was used to identify the dimension structure with best fit to the data. A multivariate linear regression analysis was also performed to determine the relationship between the occupational burnout syndrome, gender, and their current clinical rotation (obstetrics and gynecology, surgery, pediatrics, and internal medicine). Results: The EFA found that the two dimensions model best explained the data variability (61.8% of the variance). These two factors were called illusion and exhaustion. The linear regression showed that gender and the current clinical rotation were not associated to any of the two factors (P > .05). Illusion was inversely associated with exhaustion, even after fitting it with gender and current clinical rotation (P = .007and = -.33, respectively). Conclusion: The information included in the CESQT is summed up in two highly correlated dimensions: illusion and exhaustion that are independent gender and the current clinical rotation in which the students were involved.

Weight variation over time and its relevance among multidrug-resistant tuberculosis patients

Objectives: We aimed to assess the variation in patient body weight over time according to the treatment outcome among multidrug-resistant tuberculosis (MDR-TB) cases. Methods: This was a retrospective cohort study. The data of patients commencing MDR-TB therapy were analyzed. Data were collected from different public TB treatment facilities located in peri-urban areas to the south of Lima, Peru. The outcome was patient body weight (kilograms) from treatment commencement, measured monthly. A random effects model was fitted using robust standard errors to calculate 95% confidence intervals. Results: Of a total of 1242 TB cases, 243 (19.6%) were MDR-TB. Only 201 cases were included in the analysis; 127 (63.2%) were males and the mean patient age was 33.6 (standard deviation 16.2) years. Weight changes over time among the patients who were cured differed from changes in those who died during therapy (p < 0.001). Weight curve divergence was important at the end of the third, fourth, and fifth treatment months: on average, the weight difference was 2.18 kg (p < 0.001), 3.27 kg (p = 0.007), and 3.58 kg (p = 0.03), respectively, when cured patients were compared to those who died. Conclusions: Our results show that weight variation during treatment can be a useful surrogate for the treatment outcome, specifically death during therapy. MDR-TB patients with weight loss should be followed more closely, as they are at greater risk of death.

Use of automated external defibrillator in Peruvian out-of-hospital environment: improving emergency response in Latin America;

This case report relates out-ofhospital care to a patient with risk factors treated in the out-of-hospital services after cardiac arrest and ventricular fibrillation. The patient was treated according to the standards of basic life support and advanced cardiovascular life support; by applying an automated external defibrillator (AED) with favorable outcome and successful recovery of the patient from his risk of life condition. This is the first documented report with a favorable outcome in Peru, in out-ofhospital services and stresses the desirability of adopting policies for public access to early defibrillation.

Medical residency in Peru: A view beyond the real demand

Señor Editor: La problemática de los recursos humanos en salud es un área que viene cobrando mayor relevancia en la agenda nacional de Perú, donde inclusive se ha identificado como una de las prioridades nacionales de investigación en salud . Dentro de los aspectos a considerar se encuentra la escasez de profesionales de la salud y la calidad de su formación, siendo un tópico particular de interés lo concerniente a los médicos especialistas. En ese sentido, un reciente documento técnico del Ministerio de Salud da cuenta de la necesidad de este tipo de profesionales.

Si bien lo expuesto en dicho texto permite tener una visión global del asunto y servir de base para la formulación de estrategias nacionales que busquen mejorar esa situación; una institución educativa (Universidad Privada Antenor Orrego), ha tomado el citado documento para justificar la creación de nuevas plazas de segunda especialidad y realizar convocatorias extraordinarias bajo el argumento de estar enmarcados en el proceso de descentralización y la necesidad de especialistas en su región, sin considerar que este proceso no debería contradecir el principio Constitucional de la "Unicidad del Estado", es decir que los Gobiernos Regionales no deberían hacer estas convocatorias, generando controversia en la comunidad médica .

Eosinophilic and linphocitic colitis: diferent histological manifestations of a same process in a patients with chronic diarrhea

Objetivos: 1) Determinar la prevalencia de incremento de eosinófilos en mucosa colónica en pacientes con colitis linfocítica (CL). 2) Determinar la coexistencia de colitis eosinofílica (CE) en pacientes con CL. Materiales y métodos: Las biopsias colónicas de pacientes adultos con diarrea crónica diagnosticados como CL en el hospital Daniel A. Carrión durante octubre 2009 a marzo 2012 fueron revisadas de forma independiente por 2 patólogos. Microscópicamente, se investigó y cuantificó la presencia de eosinófilos en mucosa colónica. Resultados: Se incluyeron 68 casos de CL, de los cuales 76,5% tuvieron eosinófilos elevados en la mucosa colónica y en 51,4% se pudo hacer el diagnóstico de CE según los criterios establecidos. Conclusión: Tres de cuatro pacientes con CL presentan eosinófilos elevados y 1 de cada 2 pacientes con CL cumple criterios para CE.; Objectives: 1) To determine the prevalence of increased number of eosinophils in colonic mucosa of patients with lymphocytic colitis (LC). 2) To determine the coexistence of eosinophilic colitis (EC) in patients with lymphocytic colitis. Materials and methods: slides of adult patients with cronic diarrhea with diagnosis of LC were reviewed between October 2009 and March 2012. The number of eosinophils was quantified. Results: Sixty eight patients with LC were included. Elevated eosinophils were found in 76.5 and in 51.4% a diagnosis of EC was established. Conclusion: 3 out of 4 patients with LC had elevated eosinophils and 1 of 2 patients with LC had criteria for EC.
