It's a challenge! Empathizing with sad but not with angry individuals results in cardiovascular reactivity consistent with a challenge motivational state.

The question of what feeling with another person elicits in the empathizing individual has instigated innumerable studies mainly focusing on the affective valence of empathy and the resulting consequences for prosocial behavior (cf. the empathy-altruism debate). The present research may contribute to this long-lasting debate by examining the cardiovascular reactivity of the empathizing individual. To that effect, the biopsychosocial model of challenge and threat (Blascovich & Tomaka, 1996) was applied and impedance cardiography was implemented while individuals were instructed to feel with a target person who reacted differently to a need-causing event (with anger vs. sadness). Thereby, it is possible to test whether empathizers process coping-related cues when feeling with a target person in need. Results of one experiment (N = 160 women) revealed that empathizing with a sad (vs. an angry) target results in cardiovascular reactivity consistent with relative challenge-an energy-mobilizing state associated with relatively high resources. These findings suggest that coping-related appraisal processes influence how the empathizing individual reacts in terms of cardiovascular reactivity. This, in turn, provides novel insights regarding the affective-motivational outcomes of empathy. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Ansiedad y Síndrome Coronario Agudo: un análisis en pacientes coronarios varones / Anxiety and Acute Coronary Syndrome: an analysis in male coronary patients

La Enfermedad Coronaria es una de las principales preocupaciones sanitarias debido a su alta prevalencia. Particularmente, la ansiedad se relaciona con el aumento del riesgo de contraer esta enfermedad, resultando un predictor independiente de los eventos cardíacos adversos. Objetivo: Evaluar la probable influencia de la ansiedad sobre la ocurrencia del Síndrome Coronario Agudo (SCA), comparando los niveles de ansiedad rasgo/estado en pacientes varones con SCA, respecto a sujetos varones sin SCA. Método: Estudio no experimental, descriptivo-comparativo/transversal con grupo cuasi-control. La muestra consta de 213 sujetos varones de 45 a 75 años de edad: 107 tenían diagnóstico de SCA (Grupo I) y 107 no lo tenían (Grupo II). Los instrumentos administrados fueron el Cuestionario de datos generales y clínicos y el Inventario de Ansiedad rasgo/estado. Resultados: Se hallaron diferencias a favor del Grupo I (con SCA) en los niveles de ansiedad estado y rasgo, en comparación con el Grupo 2 (sin SCA), indicando la influencia de esta variable en la ocurrencia del SCA. Discusión: Los datos apoyan la hipótesis, coincidiendo con estudios previos, y aportan evidencia empírica a nivel local en pacientes varones, contribuyendo a esclarecer la problemática de la vulnerabilidad psicosocial de este paciente coronario.

Quality of life in patients with vascular malformations of the lower extremity.

With the exception of capillary malformations (port-wine stains), the adverse psychosocial effects of vascular malformations have not received much attention in the medical literature. We, therefore, studied health related quality of life of patients with vascular malformations located primarily on the lower extremity, who presented to us over a 10-year period. Patient's self-assessment of quality of life was measured by the Multiple Outcomes Study (MOS) Short Form Health Survey Questionnaire (SF-36). Several possible predictors were also examined. Eighty-one patients (33 male, 48 female), aged 14-61 years, completed the SF-36. Seventy-one patients (88%) had a low flow lesion. Twenty-three patients (28%) had hypertrophy of the lower extremity, while 11 patients (14%) had hypotrophy. Sixty-nine patients (85%) had the vascular malformation located only on the lower extremity. Six (7%) also had their upper extremity (hand) involved, and 20 patients (24.7%) had >10% TBSA affected. Eight patients (10%) needed special shoes. Fifty-one patients (63%) had a previously performed MRI, of which 62.7% (32/51) had muscle involvement. Fifty-one patients (63%) had been operated on. Of the 34 patients wearing elastic compression stockings, 25 patients (74%) indicated that they were satisfied with the stockings. Compared to the general population sample, the SF-36 questionnaire indicated that our vascular malformation patients reported impaired vitality and higher levels of pain, while no differences were seen regarding the other dimensions of quality of life. Demographic, clinical and therapy characteristics could explain quality of life only to a limited extent. Explained variability of the SF-36 dimensions ranged from 0% for mental health to 34.5% for role functioning physical. To our surprise, this study suggests that patients with vascular malformations located primarily on the lower extremity do not have a greatly decreased quality of life when compared to the general Dutch population.

Oral glutamine challenge and magnetic resonance spectroscopy in three patients with congenital portosystemic shunts.

BACKGROUND/AIMS: Congenital portosystemic shunts are rare abnormalities of liver vasculature that can cause neurological symptoms, probably secondarily to the effects of the metabolism of ammonia in the brain. Our aim was to investigate the relationship between capillary blood ammonia after oral glutamine challenge and magnetic resonance spectroscopy in three patients with congenital portosystemic shunts. METHODS: Neuropsychological tests, oral glutamine challenge and magnetic resonance spectroscopy were performed at baseline and after 6 months of follow-up in three patients with congenital portosystemic shunts. The results were compared to those obtained in a group of six cirrhotic patients with prior episodes of hepatic encephalopathy and healthy controls. RESULTS: Patients with congenital portosystemic shunts exhibited abnormalities of neuropsychological tests, magnetic resonance spectroscopy and a response to the oral glutamine challenge similar to those observed in patients with cirrhosis. The intensity of the rise of brain glutamine was correlated to the area under the curve of ammonia after the oral glutamine challenge (R=0.72). CONCLUSIONS: Neurological manifestations of patients with congenital portosystemic shunts are mediated through similar mechanisms that are involved in the pathogenesis of hepatic encephalopathy. The area under the curve appears to be the better parameter that defines the response to the oral glutamine challenge.
