RESUMO
HLA is a polymorphic antigen presenter which has provided valuable information on the susceptibility of populations to viruses. Therefore, the study of HLA can reveal specific susceptibility or resistance alleles to severe COVID-19 in an ethnically dependent manner. This pilot study investigated HLA alleles associated with COVID-19 severity in Tapachula, Chiapas, Mexico. A total of 146 Mexican Mestizos were typed for HLA class I and II using PCR-SSP. The patients were classified according to the outcome (death or improvement) and the infection's severity (mild or severe). In addition, a group of exposed uninfected individuals was included. HLA-A*68 was found to be a protective allele against the severe infection and fatal outcome; pC = 0.03, OR = 0.4, 95% CI =0.20-0.86, and pC =0.009, OR = 0.3, 95% CI =0.13-0.71 respectively. HLA-DRB1*03 also appears to be a protective factor against fatal outcome pC = 0.009, OR = 0.1, 95%IC = 0.01-0.66; however, the low frequency of this allele in the studied population limits the statistical power. The severity and fatal outcome of COVID-19 patients in Tapachula, Chiapas depend more on the lack of resistance than susceptibility HLA alleles.

BACKGROUND: Psychosocial risk factors influence the course of transplantation. Psychosocial evaluation is an important part of pre-transplantation evaluation processes, yet there are no standardized instruments in Spanish. OBJECTIVE: To translate, adapt, and test the reliability of the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) in organ and cell transplantation patients in the Spanish context. METHOD: A Spanish version was developed and adapted using WHO's guidelines. The first 30 candidates' SIPAT interviews were recorded and scored by four independent examiners to test the inter-rater reliability. The internal consistency of the SIPAT items was calculated with a sample of 150 heart, liver, and allogeneic haematopoietic stem cell transplant candidates. Evaluations were conducted by SIPAT-trained and transplantation-experienced clinical psychologists and psychiatrists. RESULTS: Stanford Integrated Psychosocial Assessment for Transplantation achieved excellent intra-class correlation reliability coefficients between investigators (ICC = 0.93 for the general score and from 0.77 to 0.94 for domain scores). Good internal consistency was found with Cronbach's alpha of 0.84 (from 0.69-0.71 for domains). DISCUSSION: This study presents the translated and adapted version of SIPAT. It has been found to have strong inter-rater reliability and good internal consistency. Further research is needed to confirm reliability (eg, test-retest) and establish its validity (eg, concurrent, predictive).

INTRODUCTION: The clinical management of patients with psychotic disorders (PDs) can be particularly complex if it takes place in the context of consultation-liaison psychiatry (CLP) services within a general hospital. However, there are few studies specifically investigating the acute treatment procedures for these patients in CLP settings. OBJECTIVES: To examine the characteristics of a sample of inpatients with a primary PD referred to a CLP service over a 10-year period and to compare the clinical features of this subgroup with patients with other diagnoses (ODs). MATERIALS AND METHODS: Observational and descriptive study over a 10-year period (2005-2014) assessing prospectively adult inpatients admitted to non-psychiatric units of the University Clinical Hospital of Barcelona who were consecutively referred to our CLP service. We performed a posthoc analysis to compare the clinical features between the subgroup of patients with PDs and the rest of patients who meet the criteria for ODs. RESULTS: We requested 393 consultations for patients who either already had the diagnosis of a primary PD and 9,415 for patients with ODs. Our results showed that patients with PDs were younger than the patients with ODs, had a higher prevalence of somatic illnesses related with an unhealthy lifestyle (such as infectious, endocrine, or metabolic diseases), less frequency of cancer, and a need to receive a more intensive psychiatric care. CONCLUSIONS: Inpatients with PDs referred to CLP have different clinical features compared with those who met the criteria for ODs. They are a highly complex group with specific psychiatric care needs.

OBJECTIVE: Previous research has described the characteristics of Consultation-liaison psychiatry (CLP) services over one or more years. The aim of this paper was to examine the patterns of a large sample of patients receiving CLP service over a 10-year-period (2005–2014) and to determine the possible changes over time of the clinical practice. The sample size of our study, the duration of the observation period and the application of standardized operating procedures for acquiring and coding data, will provide more robust evidence than has been reported by most similar studies published in the last years. METHODS: Longitudinal observational and descriptive study. Data were collected prospectively with standardized operating procedures on consecutive inpatient consultation requests to the University Clinical Hospital of Barcelona CLP service. RESULTS: 9,808 psychiatric consultation were requested (referral rate=2.2%). The referrals to our CLP service were requested mainly by medical units. The most frequent psychiatric diagnoses were alcohol-related disorders, delirium and adjustment disorders. The mean percentage of patients treated with psychopharmacologic drugs was 81.6%. The mean length of the hospital stays of patients with psychiatric comorbidity referred to our CLP service was significantly longer than that of all the admissions to the hospital during that period. Most of the studied variables remained constant over the 10-year-period. However, some somatic diagnoses at admission, reasons for referral and recommendations of psychotropic drugs presented significant changes. CONCLUSIONS: Despite the continuous evolution and changes of several factors in the last two decades, like the health care systems, the clinical practice of CLP services has been quite stable over time. However, our results support the idea of a non-static specialty.

INTRODUCTION: Patients with bipolar disorder (BD) are frequently exposed to traumatic events which worsen disease course, but this study is the first multicentre randomised controlled trial to test the efficacy of a trauma-focused adjunctive psychotherapy in reducing BD affective relapse rates. MATERIALS AND METHODS: This multicentre randomised controlled trial included 77 patients with BD and current trauma-related symptoms. Participants were randomised to either 20 sessions of trauma-focused Eye Movement Desensitization and Reprocessing (EMDR) therapy for BD, or 20 sessions of supportive therapy (ST). The primary outcome was relapse rates over 24-months, and secondary outcomes were improvements in affective and trauma symptoms, general functioning, and cognitive impairment, assessed at baseline, post-treatment, and at 12- and 24-month follow-up. The trial was registered prior to starting enrolment in clinical trials (NCT02634372) and carried out in accordance with CONSORT guidelines. RESULTS: There was no significant difference between treatment conditions in terms of relapse rates either with or without hospitalisation. EMDR was significantly superior to ST at the 12-month follow up in terms of reducing depressive symptoms (p=0.0006, d=0.969), manic symptoms (p=0.027, d=0.513), and improving functioning (p=0.038, d=0.486). There was no significant difference in dropout between treatment arms. CONCLUSIONS: Although the primary efficacy criterion was not met in the current study, trauma-focused EMDR was superior to ST in reducing of affective symptoms and improvement of functioning, with benefits maintained at six months following the end of treatment. Both EMDR and ST reduced trauma symptoms as compared to baseline, possibly due to a shared benefit of psychotherapy. Importantly, focusing on traumatic events did not increase relapses or dropouts, suggesting psychological trauma can safely be addressed in a BD population using this protocol.
RESUMO
Psychogenic Non-Epileptic Seizures (PNES) are paroxysmal episodes of altered behavior that superficially resemble epileptic seizures but lack both the expected electroencephalographical epileptic changes and the association to dysfunction of central nervous system. They account for 17 to 30% of the population admitted to epilepsy units of tertiary hospitals for evaluation of seizures refractory to the pharmacological treatment. These episodes include most of the paroxysmal non-epileptic events and diverse studies have found a high prevalence of multiple psychiatric disorders during the lifetime. The simultaneous presence of 2 or more psychiatric disorders has even been observed in 70% of the patients. When there is evidence on the absence of real epileptic seizures, the first step is to slowly suppress the antiepileptic treatment. After, adequate psychopharmacological treatment should be initiated in relationship with the psychopathological state of the patient. The different emotional and psychological variables that may be affecting the appearance and perpetuation of PNES must be identified and then resolved with psychological treatment. The aim of the present case report is to present the difficulties of differential diagnosis between epilepsy and PNES, emphasizing the great importance of both neurological and psychiatric management in the treatment of these clinical symptoms.

Introducción. El manejo clínico de los pacientes con trastornos psicóticos (TPs) es particularmente complejo si se lleva a cabo en el contexto de los servicios de psiquiatría de enlace e interconsulta (PEI) de un hospital general. Sin embargo, disponemos de pocos estudios que hayan investigado de forma específica los procedimientos asistenciales de tratamiento agudo para estos pacientes en entornos PEI. Objetivos. Examinar las características de una muestra de pacientes hospitalizados que presentan un TPs primario, que son remitidos a un servicio de PEI durante un período de 10 años y comparar las características clínicas de este subgrupo con respecto a los pacientes con otros diagnósticos (OD). Material y métodos. Estudio observacional y descriptivo llevado a cabo durante un período de 10 años (2005-2014), evaluando prospectivamente pacientes adultos ingresados en unidades no psiquiátricas del Hospital Clínico Universitario de Barcelona, que fueron remitidos de forma consecutiva a nuestro servicio de PEI. Realizamos un análisis post-hocpara comparar las características clínicas entre el subgrupo de pacientes con TPs y el resto de pacientes que cumplían los criterios para OD. Resultados. Se recibieron 393 interconsultas referentes a pacientes que presentaban un diagnóstico de TPs primario y 9.415 derivaciones de pacientes con OD. Nuestros resulta-dos mostraron que los pacientes con TPs eran más jóvenes que los pacientes con OD, tenían una mayor prevalencia de enfermedades somáticas relacionadas con un estilo de poco saludable (como enfermedades infecciosas, endocrinas o metabólicas), una menor frecuencia de cáncer y una necesidad de recibir asistencia psiquiátrica de forma más intensiva. Conclusiones. Los pacientes hospitalizados con TPs que son remitidos a los servicios de PEI tienen diferentes características clínicas en comparación con aquellos que cumplen con los criterios para OD. Se trata de un grupo complejo, con necesidades específicas en cuanto a la atención psiquiátrica

In spite of the guidelines and consensus on its indications and application, electroconvulsive therapy (ECT) continues to be one of the therapeutic procedures with less knowledge on its mechanism of action. It is interesting to evaluate the way in which the factors that modulate the convulsant activity can be modified by this therapy and its relation with the therapeutic effect. The aim of the present article is to review, in the context of neurobiological theories, the bibliography regarding the electrophysiological mechanisms of action of ECT, mainly the anticonvulsant hypothesis. Having better knowledge about these mechanisms can achieve an improvement in the clinical practice and provide a starting point to search for alternative treatments based on the same physical bases. After doing a study of all the papers and reference books, those works which, according to their methodology and design, provide relevant scientific information with regard to the principal topic of this review and that have been published between 1993 and 2007 were selected. In order to provide better consistency to the text, a series of articles prior to 1993 that were considered important within the setting studied have been included, since they establish the theoretical bases of ECT and have been frequently mentioned after their sublication. The scientific evidence obtained is systematized into three sections: basic concepts, neurophysiological hypotheses and electrophysiological findings.

Objetivo. Existen diversas investigaciones previas que han descrito las características de distintos servicios hospitalarios de Psiquiatría de Enlace e Interconsulta (PEI) a lo largo de un periodo de tiempo de uno o más años. El propósito del presente artículo es el de examinar las características de una muestra amplia de pacientes remitidos a un servicio hospitalario de PEI, durante un período de 10 años (2005-2014) y determinar los posibles cambios de la práctica clínica a lo largo del tiempo. El tamaño muestral de nuestro estudio, la duración del periodo de observación y la aplicación de procedimientos estandarizados para la obtención y codificación de los datos, aportan una evidencia más sólida en comparación con otros estudios similares publicados en los últimos años. Métodos. Estudio observacional, longitudinal y descriptivo. Los datos se recopilaron de forma prospectiva mediante procedimientos estandarizados, en base a las solicitudes recibidas en el servicio hospitalario de PEI del Hospital Clínico Universitario de Barcelona. Resultados. se solicitaron un total de 9.808 consultas psiquiátricas (tasa de derivación=2,2%). Las derivaciones a nuestro servicio fueron realizadas principalmente por unidades médicas. Los diagnósticos psiquiátricos más frecuentes fueron los trastornos relacionados con el consumo de alcohol, los cuadros confusionales y los trastornos de adaptación. El porcentaje medio de pacientes manejados con tratamiento psicofarmacológico fue del 81,6%. La duración media de las hospitalizaciones de los pacientes con comorbilidad psiquiátrica, derivados a nuestro servicio de psiquiatría de enlace, fue significativamente mayor a la estancia media global del hospital durante ese periodo. La mayoría de las variables estudiadas permanecieron constantes durante el período de 10 años. Sin embargo, algunos diagnósticos médicos en el momento del ingreso, motivos de derivación y recomendaciones de tratamiento psicofarmacológico presentaron cambios significativos. Conclusiones. A pesar de la evolución continua y los importantes cambios que se han producido en los sistemas de salud en las dos últimas décadas, la práctica clínica de los servicios de PEI ha permanecido bastante estable en el tiempo. Sin embargo, nuestros resultados apoyan la idea de una especialidad dinámica

Las crisis no epilépticas psicógenas (CNEP) son episodios paroxísticos de alteración conductual, que superficialmente parecen crisis epilépticas verdaderas, pero sin los cambios electroencefalográficos esperables ni la asociación a disfunción del sistema nervioso central. Suponen entre un 17 y un 30% de la población atendida en unidades de epilepsia de hospitales de tercer nivel para evaluación de crisis refractarias al tratamiento farmacológico. Estas crisis comprenden la mayoría de eventos paroxísticos no epilépticos y diversos estudios han encontrado una alta prevalencia a lo largo de la vida de múltiples trastornos psiquiátricos, incluso se ha observado la presencia simultánea de 2 o más diagnósticos psiquiátricos en el 70% de los pacientes. Ante la evidencia de ausencia de crisis epilépticas verdaderas, el primer paso es suprimir lentamente el tratamiento anticomicial. Posteriormente se debe iniciar un adecuado tratamiento psicofarmacológico en relación con las alteraciones psicopatológicas que muestre el paciente. Es preciso identificar las diversas variables emocionales y psicológicas que pueden estar incidiendo en la aparición y perpetuación de las CNEP y abordarlas mediante tratamiento psicológico. El objetivo de presentar este caso clínico es el de plantearlas dificultades que suele entrañar el diagnóstico diferencial entre epilepsia y CNEP, destacando la gran importancia del abordaje conjunto, neurológico y psiquiátrico, en el tratamiento de estos cuadros (AU)

La resistencia al tratamiento antipsicótico en la esquizofrenia suele aparecer en el curso de la enfermedad, generalmente años después de iniciarlo. No hay estudios que comparen los fármacos antipsicóticos de nueva generación entre sí para el tratamiento de un episodio inicial de esquizofrenia, y los datos referentes a las alternativas en caso de resistencia al tratamiento también son muy escasos. A continuación se describe el caso clínico de un paciente con un primer episodio psicótico de difícil manejo farmacológico, tanto por la escasa respuesta inicial al tratamiento como por la aparición de importantes efectos secundarios, que limitaron el perfil de los posibles antipsicóticos utilizables y sus dosis. Finalmente se instauró tratamiento con clozapina
Resistance to antipsychotic treatment in schizophrenia usually develops throughout the course of the disease, generally years after the start of treatment. There are no trials comparing the new generation of antipsychotic agents in the treatment of first-episode schizophrenia, and data on the various options available in cases of treatment resistance are limited. We describe the case of a patient with difficult pharmacological management of a first psychotic episode, due to poor initial treatment response and the presence of serious adverse effects. These factors limited the possible antipsychotic drugs that could be used as well as their doses. Finally, clozapine therapy was started (AU)

Se realizó, por primera vez en el país, una escuesta en la zona de captación de las fuentes de abastecimiento subtérraneas y superficiales de más de 5 mil habitantes para determinar los niveles de mercurio en agua y evaluarlos con referencia al valor fijado en las normas cubanas vigentes. En el 3,7 por ciento de las fuentes de abastecimiento subterráneas se detectó frecuentemente la presencia de mercurio en cifras ligeramente superiores a la norma fijada. Se encontró diferencia significativa entre las concentraciones de mercurio en cabello de 2 grupos con diferente grado de exposición a través del agua
