RESUMO

INTRODUCTION: Dispositional optimism is a personality trait significantly associated with the use of positive adaptive coping strategies as well as with perceived psychological and physical well-being, and it appears to be an important predictor of illness. OBJECTIVES: To analyse if dispositional optimism is significantly associated with the number of hospital admissions of our chronic haemodialysis patients, as well as its relationship with perceived state of health. METHODS: We studied 239 patients on chronic haemodialysis. Patients were categorised into two groups according to the variables: hospital admissions/no. of admissions in the last year and dispositional optimism (DO). We used the following variables and questionnaires: 1) Dispositional O/P using the Spanish-validated cross-cultural adaptation of the revised version of the Life Orientation Test (LOT-R) (Scheier, 1994): higher scores mean a higher degree of dispositional optimism. 2) Health-related quality of life (HRQoL) using the different aspects of the COOP/WONCA (CW) charts and its total score. In this case higher scores mean lower HRQoL. 3) Modified Charlson Comorbidity Index (mCCI). 4) Age, gender, and time on dialysis. RESULTS: Mean age was 64.8 ± 14.3 years; median time on dialysis 2.9 years (range: 0-32); and median LOT-R 21 (range 6-30). Patients considered DO had a lower risk of hospital admissions than pessimists (DP) (OR: 0.55; IC 95%: 0.32-0.94; P<.05). PD Patients that were admitted in the last year showed a significantly lower score on LOT-R (they were more pessimistic) than those that had no hospital admissions (19.4 ± 5.7 vs 22.3 ± 4.6; P=.001). We found no significant differences between admitted and not admitted patients in age, gender, time on haemodialysis and comorbidity. Admitted patients showed worse HRQoL (higher scores in total CW) than those that were not (Total CW: 22.37 vs 19.42; P<.001). PD patients had significantly higher scores than OD patients in all COOP-WONCA aspects except in aspect 1 (physical fitness) and 5 (change in health). CONCLUSIONS: Pessimistic personality trait is significantly associated with hospital admissions in chronic haemodialysis patients, regardless of age, gender and comorbidity. Optimistic patients perceived a better state of health.

RESUMO

During pregnancy, there are several physiological changes that influence the kinetics of medication administrated during this time. These physiological changes are not reestablished immediately during delivery; so, its concentration in biologic fluids is different when is administered immediately after delivery, than several weeks after. The purpose in this work was to identify the changes of pharmacocinetics constants for fenitoin and carbamacepine, in epileptic patients. When the same dose is maintained, during different times of postpartum. In 20 Mexican epileptic women, the plasma and milk concentrations of fenitoina during 60 day postpartum and in 14 carbamacepine was determined. In all the patients pharmakocinetics of anticonvulsivant, in each study period (5, 15, 30, 45 y 60 days postpartum). Excretion index of maternal milk was determined. Maximal plasmatic concentration of fentoine had no variation; however, carbamacepine was higher during the late period. There were no differences in the areas under curve and life all the middle of elimination and in excretion index.

RESUMO

Durante el embarazo existen una serie de cambios fisiológicos que influyen en la cinética de los medicamentos administrativos durante esta etapa: Estos cambios fisiológicos no se restauran inmediatamente en el parto, de tal manera que su concentración en los fluidos biológicos es diferente cuando se administra inmediatamente después del parto que varias semanas posterior al mismo. El presente trabajo tiene como propósito identificar los cambios en las constantes farmacocinéticas de fenitoína y carbamacepina, en pacientes epilépticas cuando se mantiene una misma dosis durante diferentes etapas del postparto. En 20 mujeres mexicanas epilépticas se determinó la concentración en plasma y leche de fenitoína durante 60 días postparto y en 14 se determinó carbamacepina. A todas las pacientes se les realizó la farmacocinética de los anticonvulsivantes en cada periodo de estudio (5, 15, 30, 45 y 60 días posparto) y se determinó el índice de excreción en leche materna. Las concentraciones plasmáticas de fenitoína no presentaron variaciones, sin embargo la carbanacepina fue más alta en el periodo tardió, también se observaron diferencias en las áreas bajo la curva y vida media de eliminación y en los índices de excreción
