Revisión sistemática y metaanálisis en neuroimagen y conciencia de enfermedad en psicosis no afectivas. Autores Pau Soldevila-Matías, Georgios Schoretsanitis, Diana Tordesillas-Gutierrez, Manuel J.Cuesta, Renato de Filippis, Rosa Ayesa-Arriola, Carlos González-Vivas, Esther Setién-Suero, Norma Verdolini, Julio Sanjuán, Joaquim Radua, Benedicto Crespo-Facorro Año publicación 2021 Revista Revista de Psiquiatría y Salud Mental Abstract Objective Neurological correlates of impaired insight in non-affective psychosis remain unclear. This study aimed to review and meta-analyze the studies assessing the grey matter volumetric correlates of impaired insight in non-affective psychosis. Methods This study consisted of a systematic review of 23 studies, and a meta-analysis with SDM-PSI of the 11 studies that were whole-brain and reported maps or peaks of correlation of studies investigating the grey matter volumetric correlates of insight assessments of non-affective psychosis, PubMed and OVID datasets were independently reviewed for articles reporting neuroimaging correlates of insight in non-affective psychosis. Quality assessment was realized following previous methodological approaches for the ABC quality assessment test of imaging studies, based on two main criteria: the statistical power and the multidimensional assessment of insight. Study peaks of correlation between grey matter volume and insight were used to recreate brain correlation maps. Results A total of 418 records were identified through database searching. Of these records, twenty-three magnetic resonance imaging (MRI) studies that used different insight scales were included. The quality of the evidence was high in 11 studies, moderate in nine, and low in three. Patients with reduced insight showed decreases in the frontal, temporal (specifically in superior temporal gyrus), precuneus, cingulate, insula, and occipital lobes cortical grey matter volume. The meta-analysis indicated a positive correlation between grey matter volume and insight in the right insula (i.e., the smaller the grey matter, the lower the insight). Conclusion Several brain areas might be involved in impaired insight in patients with non-affective psychoses. The methodologies employed, such as the applied insight scales, may have contributed to the considerable discrepancies in the findings. Resumen Objetivo Los correlatos neurológicos de la conciencia de enfermedad en psicosis no afectivas siguen sin estar claros. Este estudio tiene como objetivo revisar y metaanalizar los estudios que evalúan los correlatos volumétricos de la materia gris de la conciencia de enfermedad deficiente en la psicosis no afectiva. Métodos Este estudio consistió en una revisión sistemática de 23 estudios y un metaanálisis con SDM-PSI de los 11 estudios que examinaron todo el cerebro y reportaron mapas o picos de correlación de estudios que investigan los correlatos volumétricos de materia gris de evaluaciones de insight de psicosis no afectiva. Los conjuntos de datos de PubMed y OVID se revisaron deforma independiente para los artículos que informaban sobre correlaciones de neuroimagen de insight en psicosis no afectiva. La evaluación de la calidad de los estudios de imagen se realizó siguiendo enfoques metodológicos previos usando la prueba de evaluación de la calidad ABC basados en dos criterios principales: el poder estadístico y la evaluación multidimensional del insight. Los picos de correlación del estudio entre el volumen de materia gris y la conciencia de enfermedad fueron utilizados para recrear mapas de correlación cerebral. Resultados Se incluyeron veintitrés estudios de imágenes por resonancia magnética (IRM) que utilizaron diferentes escalas de conciencia de enfermedad. La calidad de los estudios revisados fue clasificada como alta en 11 estudios, moderada en 9 estudios y baja en 3 estudios. Los pacientes con insight reducido mostraron disminuciones en el volumen de materia gris cortical de los lóbulos frontal, temporal (específicamente en la circunvolución temporal superior), precúneo, cingulado, ínsula y lóbulo occipital. El metaanálisis mostró una correlación positiva entre el volumen de materia gris y la conciencia de enfermedad en la ínsula derecha (es decir, cuanto más pequeña es la materia gris, menor es el insight). Conclusiones Varias áreas del cerebro pueden estar involucradas en la conciencia de enfermedad en pacientes con psicosis no afectivas. Tanto las metodologías empleadas como las escalas para valorar la conciencia de enfermedad aplicadas pueden haber contribuido a las considerables discrepancias en los hallazgos publicados. Cita P.

Título Study Protocol—Coping With the Pandemics: What Works Best to Reduce Anxiety and Depressive Symptoms Autores Lydia Fortea, Aleix Solanes, Edith Pomarol-Clotet, Maria Angeles Garcia-Leon, Adriana Fortea, Carla Torrent, Cristina Varo, C. Mar Bonnin, Laura Montejo, Jordi Alonso, Susana Carmona, Pau Soldevila-Matías, Irene Alustiza, Daniel Arbós, Diego Hidalgo-Mazzei, Iria Grande, Eduard Vieta, Miquel Àngel Fullana, Joaquim Radua Año publicación 2021 Revista Frontiers in Psychiatry Abstract Background The coronavirus disease 2019 (COVID-19) pandemic and lockdown might increase anxiety and depressive symptoms in most individuals. Health bodies recommend several coping behaviors to protect against such symptoms, but evidence on the relationship between these behaviors and symptoms mostly comes from cross-sectional studies in convenience samples. We will conduct a prospective longitudinal study of the associations between coping behaviors and subsequent anxiety and depressive symptoms during the COVID-19 pandemic in a representative sample of the Spanish general adult population. Methods We will recruit 1,000 adult participants from all autonomous communities of Spain and with sex, age, and urbanicity distributions similar to those of their populations and assess anxiety and depressive symptoms and coping behaviors using fortnightly questionnaires and real-time methods (ecological momentary assessments) for 1 year. The fortnightly questionnaires will inquire about anxiety and depressive symptoms [General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9)] and the frequency of 10 potential coping behaviors (e.g., follow a routine) during the past 2 weeks. In addition, we will collect several variables that could confound or moderate these associations. These will include subjective well-being [International Positive and Negative Affect Schedule Short Form (I-PANAS-SF) and Satisfaction with Life Scale (SWLS)], obsessive-compulsive symptoms [Obsessive Compulsive Inventory-Revised (OCI-R)], personality and emotional intelligence [International Personality Item Pool (IPIP) and Trait Emotional Intelligence Questionnaire Short Form (TEIQue-SF)], sociodemographic factors (e.g., work status, housing-built environment), and COVID-19 pandemic-related variables (e.g., hospitalizations or limitations in social gatherings). Finally, to analyze the primary relationship between coping behaviors and subsequent anxiety and depressive symptoms, we will use autoregressive moving average (ARMA) models. Discussion Based on the study results, we will develop evidence-based, clear, and specific recommendations on coping behaviors during the COVID-19 pandemic and lockdown. Such suggestions might eventually help health bodies or individuals to manage current or future pandemics. Cita Fortea L, Solanes A, Pomarol-Clotet E, et al.

Título Precuneus and insular hypoactivation during cognitive processing in first-episode psychosis: Systematic review and meta-analysis of fMRI studies./ Hipoactivación precúnea e insular durante el procesamiento cognitivo en el primer episodio psicótico: revisión sistemática y metaanálisis de estudios de fMRI.

Abstract Introduction The neural correlates of the cognitive dysfunction in first-episode psychosis (FEP) are still unclear. The present review and meta-analysis provide an update of the location of the abnormalities in the fMRI-measured brain response to cognitive processes in individuals with FEP. Methods Systematic review and voxel-based meta-analysis of cross-sectional fMRI studies comparing neural responses to cognitive tasks between individuals with FEP and healthy controls (HC) according to PRISMA guidelines. Results Twenty-six studies were included, comprising 598 individuals with FEP and 567 HC. Individual studies reported statistically significant hypoactivation in the dorsolateral prefrontal cortex (6 studies), frontal lobe (8 studies), cingulate (6 studies) and insula (5 studies). The meta-analysis showed statistically significant hypoactivation in the left anterior insula, precuneus and bilateral striatum. Conclusions While the studies tend to highlight frontal hypoactivation during cognitive tasks in FEP, our meta-analytic results show that the left precuneus and insula primarily display aberrant activation in FEP that may be associated with salience attribution to external stimuli and related to deficits in perception and regulation.

Título Longitudinal studies of functional magnetic resonance imaging in first-episode psychosis: A systematic review Autores Carlos González-Vivas, Pau Soldevila-Matías, Olga Sparano, Gracián García-Martí, Luís Martí-Bonmatí, Benedicto Crespo-Facorro, André Aleman, Julio Sanjuan. Año publicación 2019 Revista European Psychiatry. The Journal of the European Psychiatric Association. Abstract Background Little is known about changes in brain functioning after first-episode psychosis (FEP). Such knowledge is important for predicting the course of disease and adapting interventions. Functional magnetic resonance imaging has become a promising tool for exploring brain function at the time of symptom onset and at follow-up. Method A systematic review of longitudinal fMRI studies with FEP patients according to PRISMA guidelines. Resting-state and task-activated studies were considered together. Results Eleven studies were included. These reported on a total of 236 FEP patients were evaluated by two fMRI scans and clinical assessments. Five studies found hypoactivation at baseline in prefrontal cortex areas, two studies found hypoactivation in the amygdala and hippocampus, and three others found hypoactivation in the basal ganglia. Other hypoactivated areas were the anterior cingulate cortex, thalamus and posterior cingulate cortex. Ten out of eleven studies reported (partial) normalization by increased activation after antipsychotic treatment. A minority of studies observed hyperactivation at baseline. Conclusions This review of longitudinal FEP samples studies reveals a pattern of predominantly hypoactivation in several brain areas at baseline that may normalize to a certain extent after treatment. The results should be interpreted with caution given the small number of studies and their methodological and clinical heterogeneity. Cita González-Vivas C, Soldevila-Matías P, Separan O, et al.

Título First-Episode Psychotic Patients Showed Longitudinal Brain Changes Using fMRI With an Emotional Auditory Paradigm Autores Carlos González-Vivas, Gracián García-Martí, Pau Soldevila-Matías, Roberto Sanz-Requena, Eduardo J. Aguilar, María José Castro-Bleda, Luis Martí-Bonmatí, Julio Sanjuan Año publicación 2020 Revista Frontiers in Psychiatry. Abstract Most previous longitudinal studies of functional magnetic resonance imaging (fMRI) in first-episode psychosis (FEP) using cognitive paradigm task found an increased activation after antipsychotic medications. We designed an emotional auditory paradigm to explore brain activation during emotional and nonemotional word processing. This study aimed to analyze if longitudinal changes in brain fMRI BOLD activation is present in patients vs. healthy controls. A group of FEP patients (n = 34) received clinical assessment and had a fMRI scan at baseline and follow-up (average, 25-month interval). During the fMRI scan, both emotional and nonemotional words were presented as a block design. Results were compared with a pair of healthy control group (n = 13). Patients showed a decreased activation at follow-up fMRI in amygdala (F = 4.69; p = 0.04) and hippocampus (F = 5.03; p = 0.03) compared with controls. Middle frontal gyrus was the only area that showed a substantial increased activation in patients (F = 4.53; p = 0.04). A great heterogeneity in individual activation patterns was also found. These results support the relevance of the type of paradigm in neuroimaging for psychosis. This is, as far as we know, the first longitudinal study with an emotional auditory paradigm in FEP. Our results suggested that the amygdala and hippocampus play a key role in psychotic disease. More studies are needed to understand the heterogeneity of response at individual level.

Título Clozapine-related drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome: a systematic review Autores Renato de Filippis,Pau Soldevila-Matías, Pasquale De Fazio, Daniel Guinart, Inmaculada Fuentes-Durá, Jose M. Rubio, John M. Kane, Georgios Schorets Año publicación 2020 Revista Expert Review of Clinical Pharmacology Abstract Introduction The Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a severe, multiorganic, and potentially life-threatening drug-induced hypersensitivity reaction, linked to several common drugs, including antiepileptics, antibiotics, and several psychotropic drugs, including clozapine. Due to the importance of clozapine in the management of treatment-resistant schizophrenia, a systematic review and characterization of clozapine-related DRESS syndrome is long overdue. Areas covered This systematic review was conducted following PRISMA guidelines. PubMed, Embase, PsychINFO, and the Cochrane Library databases were independently reviewed up to 1 November 2019 for articles reporting clozapine-related DRESS syndrome cases. The RegiSCAR score system was applied to systematically characterize the clinical presentations of selected studies. Expert opinion Clozapine-related DRESS syndrome was reported in six patients from four articles. Five patients received polypharmacy. Skin rash and liver involvement with elevated liver enzymes were very common. No fatal cases were found. Treatment mainly included clozapine discontinuation and immunosuppression. The mismatch between incidences of DRESS with other responsible drugs, the common misdiagnosis of this syndrome, and the fact that an extensive literature search only identified six cases suggests that clozapine-related DRESS may be overlooked. It is, therefore, necessary to optimize diagnostic strategies to identify immune-related side effects of clozapine. Cita De Filippis R, Soldevila-Matías P, De Fazio P, et al.
