Perfil de personalidad en pacientes con trasplante renal: el modelo alternativo de los cinco factores / Personality profile of kidney transplant patients: the alternative five factor model

Resumen Introducción: la investigación sobre rasgos de personalidad en pacientes con trasplante renal es limitada. El objetivo de este estudio fue describir el perfil de personalidad de pacientes con trasplante renal, utilizando el modelo alternativo de cinco factores (AFFM), y compararlo con población estándar española. Material y métodos: la personalidad fue evaluada mediante el Zuckerman-Kuhlman Personality Questionnaire (ZKPQ). Una muestra de 207 pacientes con trasplante renal se emparejó por edad y género con 207controles de la población estándar. El análisis de regresión logística permitió estudiar la aportación de cada dimensión del ZKPQ al perfil distintivo de los pacientes trasplantados. Resultados: aparecieron diferencias significativas en las dimensiones de Neuroticismo-Ansiedad (p=.001), Agresión-Hostilidad (p=.009) y Actividad (p=.001), con puntuaciones bajas en pacientes trasplantados en comparación con la población estándar. La sociabilidad (p=.024) fue significativamente mayor en pacientes trasplantados. En el análisis de regresión, las bajas puntuaciones en Neuroticismo-Ansiedad (p=.005) y Actividad (p=.001) fueron predictores significativos para caracterizar los rasgos de personalidad de pacientes trasplantados. Conclusiones: desde el AFFM, los pacientes con trasplante renal muestran un perfil diferente de personalidad comparado con la población estándar, con bajas puntuaciones en las dimensiones de Neuroticismo-Ansiedad y Actividad.

Abstract Background: There is limited research on personality traits that characterized kidney transplant patients. The aim of this study was to describe personality profile of kidney transplant patients using the Alternative Five Factor Model (AFFM), and compared it with the Spanish standard population. Method: Personality was assessed using the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ). A sample of 207 kidney transplant patients was matched by age and gender with 207 standard range controls. A logistic regression analyses was utilized to study the contribution of each ZKPQ dimension to describe the distinctive transplant patient's profile. Results: Significant differences were showed in Neuroticism-Anxiety (p=.001), Aggression-Hostility (p=.009), and Activity (p=.001) dimensions, with lower scores on transplant patients compared with standard population. But Sociability (p=.024) was significantly higher on kidney transplant patients. In logistic regression analysis low scores on Neuroticism-Anxiety (p=.005) and Activity (p=.001) were the significant predictors to characterize personality traits of kidney transplant patients. Conclusions: Kidney transplant patients had a differential profile under the AFFM compared to standard range sample, with lower scores on Neuroticism-Anxiety and Activity dimensions.

Increased cardiovascular and anxiety outcomes but not endocrine biomarkers of stress during performance of endoscopic sinus surgery: a pilot study among novice surgeons.

OBJECTIVE: To compare psychophysiological responses among novice surgeons during performance of endoscopic sinus surgery (ESS). DESIGN: Randomized study. SETTING: Academic institution. PARTICIPANTS: Fifteen novice surgeons. MAIN OUTCOME MEASURES: The psychophysiological effects of performing ESS were assessed among 15 novice surgeons at 30 minutes before (T - 30), at the beginning of (T0), at 15 minutes (T15), and 45 minutes (T45) during, and at 30 minutes after (T + 30) surgery. Participants were randomized to perform ESS with a computer-assisted surgery system, to perform ESS without a computer-assisted surgery system, or to be evaluated on a nonsurgical day (control day). Measured were the State-Trait Anxiety Inventory score, Visual Analog Anxiety Scale score, heart rate, blood pressure, and plasma cortisol and prolactin levels. RESULTS: Anxiety as measured by the State-Trait Anxiety Inventory score was not modified by the experimental conditions. The mean (SEM) Visual Analog Anxiety Scale score increased (P < .05) during ESS at T0 (2.45 [0.32]), T15 (3.46 [0.50]), and T45 (3.17 [0.46]) compared with the control day (1.19 [0.19], 1.32 [0.26], and 1.20 [0.19], respectively). The mean (SEM) systolic blood pressure (in millimeters of mercury) increased (P < .05) during ESS at T0 (127 [2]), T15 (126 [3]), and T45 (125 [2]) compared with the control day (120 [3], 119 [4], and 116 [3], respectively). The mean (SEM) heart rate (in beats per minute) increased during ESS but was significant only at T15 (73 [4]) compared with the control day (64 [3]). The mean (SEM) plasma cortisol level (in micrograms per deciliter) increased 29% above baseline during performance of ESS and reached a maximum peak at T45 (12.6 [1.2]) compared with the control day (9.7 [1.1]), while prolactin levels did not change. The Visual Analog Anxiety Scale score, heart rate, blood pressure, and endocrine biomarkers of stress were not significantly modified during performance of ESS with a computer-assisted surgery system. CONCLUSION: This study demonstrates for the first time that cardiovascular and anxiety changes during performance of ESS are not associated with increased levels of prototypical endocrine stress hormones.
