RESUMO

Introducción La investigación científica fomenta el desarrollo de competencias esenciales para la práctica médica. Sin embargo, la participación estudiantil en proyectos de investigación es baja, con múltiples limitaciones y percepción de habilidades investigativas deficientes por parte de los estudiantes. Los objetivos de este estudio son describir la organización de las dos jornadas de estudiantes de medicina realizadas por la Sociedad Científica de Estudiantes de Medicina de la Universidad de Valparaíso y caracterizar los trabajos presentados. Finalmente, se realizan recomendaciones para la promoción de la investigación científica en estudiantes de medicina. Métodos Se realizó un estudio transversal analítico que incluyó todos los trabajos presentados en las jornadas. Resultados Las jornadas comprendieron cuatro fases: inscripción, evaluación, selección y presentación. Se recibieron 399 trabajos. Se presentaron 157 reportes de caso y 12 estudios transversales, incluyendo 797 autores (56,7% mujeres) de 21 universidades. Mayormente, los primeros autores fueron mujeres cursando el ciclo de internados en universidades estatales. Las especialidades con mayor representación fueron medicina interna (32,5%), pediatría (18,3%) y cirugía (13%). En los reportes de caso, la sección mejor evaluada fue el título (6,66 ± 0,76) y la peor evaluada la discusión (6,17 ± 0,84). Los reportes de caso provenientes de universidades privadas obtuvieron una calificación significativamente mayor en seis de los ocho ítems evaluados. Conclusiones La mayor participación estuvo representada por estudiantes cursando el ciclo de internados que presentaron reportes de caso. La sección peor evaluada fue la discusión, lo que podría reflejar dificultades en el proceso de investigación. Es crucial aumentar la participación estudiantil desde los primeros años de la carrera y fomentar su involucramiento en investigación. Se requieren más estudios para evaluar la participación y las barreras estudiantiles en investigación científica.


Introduction Scientific research promotes the development of essential skills for medical practice. However, student participation in research projects is low, with multiple limitations and students' perceptions of deficient research skills. This study aims to describe the organization of the two medical student conferences held by the Scientific Society of Medical Students of the Universidad de Valparaíso and to analyze the papers presented. Finally, we make recommendations for promoting scientific research among medical students. Methods An analytical cross-sectional study was conducted, including all the presentations given at the conferences. Results The conferences comprised four phases: registration, evaluation, selection, and presentation. A total of 399 papers were received. A total of 157 case reports and 12 cross-sectional studies were presented, including 797 authors (56.7% women) from 21 universities. Most of the first authors were women in the internship cycle at public universities. The specialties with the highest representation were internal medicine (32.5%), pediatrics (18.3%) and surgery (13%). In the case reports, the best-evaluated section was the title (6.66 ± 0.76), and the worst-evaluated section was the discussion (6.17 ± 0.84). The case reports from private universities scored significantly higher in six of the eight items assessed. Conclusions Greater participation was represented by students in their internship cycle presenting case reports. The worst evaluated section was the discussion, which could reflect difficulties in the research process. It is crucial to increase student participation from the first years of the career and encourage their involvement in research. More studies are needed to evaluate student participation and barriers to scientific research.

RESUMO

El constructo de alto riesgo clínico de psicosis ha favorecido la investigación en la neurobiología de los estadios previos a la psicosis, así como también en intervenciones preventivas. Se trata de personas jóvenes que presentan síntomas psicóticos de menor intensidad o de menor frecuencia en un tiempo determinado, o bien tienen antecedentes genéticos de trastornos psicóticos sumados a un deterioro significativo del funcionamiento. Las escasas intervenciones existentes para esta población cuentan con un bajo nivel de evidencia. La actividad y el ejercicio físico han demostrado ser parte de la terapia de múltiples trastornos psiquiátricos, mientras que el sedentarismo sería un factor favorecedor de la psicosis. Efectivamente, las personas en alto riesgo clínico de psicosis presentan un peor estado físico asociado a mayor sedentarismo y hábitos de vida poco saludables. Se ha propuesto que el ejercicio genera un efecto biológico positivo sobre el hipocampo y las áreas circundantes, regiones que estarían involucradas en la fisiopatología de la psicosis. Algunos estudios experimentales han mostrado una disminución en la sintomatología psicótica en pacientes en alto riesgo clínico de psicosis que han seguido pautas de ejercicio físico. También dan cuenta de cambios morfofuncionales en estructuras cerebrales. Si bien existen barreras para la implementación de esta intervención, se trata de una intervención segura y factible. Es necesario realizar una mayor cantidad de estudios experimentales de una escala mayor para medir su eficacia, generando evidencia científica que permita eventualmente integrar el ejercicio físico a las guías de práctica clínica como una recomendación sistemática.


The concept of clinical high risk for psychosis has favored research in the neurobiology of the stages prior to psychosis, as well as in preventive interventions. This group is made up of young people with: (1) psychotic symptoms of less intensity or less frequency during a brief time or having genetic history of psychotic disorders associated to a significant deterioration in functioning. The few existing interventions for this population have a low level of evidence. Physical activity and exercise have been shown to be part of the therapy for multiple psychiatric disorders, while a sedentary lifestyle would be a factor that favors psychosis. Indeed, people in clinical high risk for psychosis present a worse physical condition associated with a greater sedentary lifestyle and unhealthy habits. It has been proposed that exercise generates a positive biological effect on the hippocampus and surrounding areas, regions that would be involved in the pathophysiology of psychosis. Some experimental studies have shown a decrease in psychotic symptoms in patients with clinical high risk for psychosis who have followed physical exercise guidelines, as well as morphofunctional changes in brain structures. Although there are barriers to the implementation of this intervention, it is safe and feasible. It is necessary to conduct a greater number of experimental studies on a larger scale to measure its efficacy, generating scientific evidence that will eventually allow physical exercise to be included in clinical practice guidelines as a systematic recommendation for clinical high risk for psychosis.

RESUMO

Inicialmente la catatonía fue un componente clínico de algunas formas de esquizofrenia, pero la evidencia básica y epidemiológica demuestra su vinculación con múltiples cuadros somáticos y psiquiátricos. Se describen y analizan conceptos clínicos, etiológicos, fisiopatológicos y terapéuticos actuales respecto a la catatonía. Se realizó una revisión narrativa amplia de artículos publicados en MEDLINE/PubMed. El diagnóstico es clínico y puede apoyarse en exámenes complementarios, pero existen instrumentos psicométricos con distinto énfasis clínico. Los subtipos más validados son el inhibido y el excitado. Se asocia mayormente a patologías somáticas, neurológicas, afectivas, psicóticas y del espectro autista. En su fisiopatología se han estudiado factores genéticos relacionados con los oligodendrocitos. Algunos hallazgos señalan un desbalance en la neurotransmisión y densidad de receptores de GABA y dopamina, hecho concordante con su función en las vías motoras y la respuesta terapéutica con benzodiacepinas. Asimismo, se ha analizado la actividad glutamatérgica, desde el modelo fisiopatológico de la encefalitis autoinmune. Las vías córtico-corticales y córtico-subcorticales tendrían un rol central, incluyendo estructuras como las cortezas orbitofrontal y temporal, núcleos basales y tronco encefálico, involucradas en la toma de decisiones, regulación emocional, almacenamiento, planificación y elaboración motora. Las principales líneas terapéuticas son las benzodiacepinas y la terapia electroconvulsiva. Otras intervenciones estudiadas son el zolpidem, antipsicóticos, estabilizadores del ánimo, moduladores glutamatérgicos y estimulación magnética transcraneal. Los nuevos hallazgos neurobiológicos discuten los preceptos nosológicos y terapéuticos, renovando el ciclo en la conceptualización de la catatonía. Se destaca el componente afectivo del síndrome psicomotor y el rol de las intervenciones que apunten a su modulación.


Catatonia was initially a clinical presentation of certain types of schizophrenia, but basic and epidemiological evidence has demonstrated its association with multiple somatic and psychiatric conditions. We describe and discuss current clinical, etiological, pathophysiological, and therapeutic concepts regarding catatonia. We conducted a broad narrative review of articles published in MEDLINE/PubMed. The diagnosis is clinical and can be supported by additional tests, but there are psychometric instruments with different clinical focus. The most validated subtypes are inhibited and excited catatonia. It is mostly associated with somatic, neurological, affective, psychotic, and autistic spectrum disorders. Genetic factors related to oligodendrocytes have been studied in its pathophysiology. Some findings point to an imbalance in neurotransmission and density of GABA and dopamine receptors, consistent with their function in motor pathways and therapeutic response with benzodiazepines. Likewise, glutamatergic activity has been analyzed from the pathophysiological model of autoimmune encephalitis. The cortico-cortical and cortico-subcortical pathways would have a central role, including structures such as the orbitofrontal and temporal cortex, basal nuclei, and brainstem, involved in decision-making, emotion regulation, storage, planning, and motor processing. The main therapeutic lines are benzodiazepines and electroconvulsive therapy. Other interventions studied are zolpidem, antipsychotics, mood stabilizers, glutamatergic modulators, and transcranial magnetic stimulation. New neurobiological findings challenge nosological and therapeutic precepts, renewing the cycle in the conceptualization of catatonia. We highlight the affective component of the psychomotor syndrome and the role of interventions aimed at its modulation.

RESUMO

La mayoría de los trastornos psiquiátricos tienen una heredabilidad de moderada a alta, con diferentes arquitecturas genéticas. Aunque la investigación genética en psiquiatría ha tenido un avance progresivo, sus hallazgos, interpretación e impacto en la psiquiatría clínica resultan desconocidos para la mayoría de los profesionales de salud mental. En este artículo se abordan conceptos clave sobre genética para el entendimiento de algunas entidades clínicas, con énfasis en la nomenclatura genética y los tipos de mutaciones. Particularmente, se plantea el rol de la herencia en los inicios de la investigación genética en psiquiatría, los diseños de estudio más utilizados y sus principales objetivos. Por otro lado, se revisan algunas bases de datos genéticas y genómicas que pueden ser de utilidad para la práctica clínica. Entre ellas destacan , ClinVar, Ensembl y . Finalmente, se plantea una viñeta clínica en donde es posible aplicar algunas de las herramientas de la medicina genómica. Debido a que la evidencia en genética psiquiátrica se basa en estudios realizados en poblaciones con origen ancestral europeo o norteamericano, es de suma relevancia desarrollar estudios locales para incrementar el conocimiento y la aplicación de la medicina genómica sobre poblaciones subrepresentadas.


Most psychiatric disorders are moderate to highly heritable, often with different genetic architectures. Although genetic research in psychiatry has progressed, its findings, interpretation, and impact on clinical psychiatry are unknown to most mental healthcare professionals. This article addresses key genetic concepts to understand some clinical entities, emphasizing genetic terminology and types of mutations. Particularly, we describe the role of heritability in the early days of psychiatry genetic research, the most used study designs, and their main objectives. On the other hand, we review some genetic and genomic databases useful for clinical practice. These include Online Mendelian Inheritance in Man, ClinVar, Ensembl, and The Single Nucleotide Polymorphism Database. Finally, a clinical vignette is presented in which we can apply genomic medicine tools. Since the evidence in psychiatric genetics is based on studies carried out in European or North American ancestral populations, we must develop local studies to increase the knowledge and application of genomic medicine on underrepresented populations.

RESUMO

The mechanisms of action (MA) of electroconvulsive therapy (ECT) in affective disorders are poorly understood. We synthesized and discussed the evidence provided by primary studies and systematic reviews in humans. There are differences in the methylation of candidate genes involved in the response to ECT. Functioning of the hippocampal serotonin receptor 5-HT1B is associated with the response in patients with major depressive disorder (PMDD), while the striatal dopamine transporter would participate in the response of PMDD and in patients with bipolar disorders (BD). The only neurotrophic factor associated with ECT response was vascular endothelial growth factor. In BD, some oxidative stress metabolites had a clinical correlation, while tryptophan metabolism showed a clinical association in BD and PMDD. Furthermore, in PMDD, some neurodegeneration markers were implicated in the MA of ECT. There were no other biological dimensions associated with BD. In PMDD, multiple inflammatory mediators were associated with the clinical response (natural killer cells, tumor necrosis and growth factors, and interleukins 1, 4, 6, 10,1β). Likewise, some structures and circuits consistently involved at the morphological and functional level are the default mode network, cognitive control networks, frontal, temporal, cingulate, occipital and temporal cortices, frontal, temporal, precentral, fusiform and left angular gyri, hippocampus, thalamus and amygdala. Investigations are mostly focused on PMDD, are observational, and their samples limited, but they show relatively consistent results with clinical significance.

RESUMO

Introducción: El trastorno depresivo mayor (TDM) constituye un problema de salud pública por su alta prevalencia y consecuencias biopsicosociales. Es un desorden clínicamente heterogéneo, complejo y de curso fluctuante. En Chile, no existen estudios sobre trayectorias terapéuticas en TDM. Objetivo: Describir las trayectorias de respuesta clínica en pacientes con TDM en tratamiento en centros de Atención Primaria de Salud (APS) en Chile. Método: Estudio de cohorte prospectiva de cinco meses de seguimiento. Se incluyeron pacientes ingresados en el Programa de Garantías Explícitas en Salud de Depresión de siete centros de APS de la Región de Valparaíso, Chile. Se realizaron cuatro evaluaciones (semanas 0, 4, 12 y 20) para describir variables clínicas y sociodemográficas relacionadas con la evolución. Se elaboraron trayectorias de respuesta en relación con el curso de los síntomas depresivos. Resultados: Se incluyeron 159 participantes (93% fueron mujeres), con un promedio de 43 años de edad. Las condiciones de riesgo para TDM más frecuentemente reportadas fueron el aislamiento social o la escasa red de apoyo y haber presenciado violencia intrafamiliar durante la infancia. Se obtuvo 12 trayectorias de respuesta de un total de 16 patrones posibles. Se observan diferencias al analizar las respuestas terapéuticas entre las semanas 0 y 12 y 0 y 20. Las trayectorias más frecuentes fueron el mantenimiento o empeoramiento de la sintomatología depresiva (37,7%). Conclusiones: Los resultados muestran una variabilidad sintomática durante el transcurso de un TDM. En este seguimiento de cinco meses, más de un tercio de las participantes no mejoraron sus síntomas depresivos.


Introduction: Major depressive disorder (MDD) is a public health problem due to its high prevalence and biopsychosocial consequences. It is a clinically heterogeneous and complex disorder with a fluctuating course. In Chile, there are no studies on clinical trajectories in MDD. Objective: To describe the clinical response trajectories in patients with MDD under treatment in primary care centers (PCC) in Chile. Method: We conducted a prospective cohort study with a five-month follow-up, including patients treated in the Explicit Guarantees in Healthcare program for depression at seven PCC in the Valparaíso Region, Chile. We carried out four evaluations (weeks 0, 4, 12 and 20) to describe various clinical and sociodemographic variables related to the therapeutic evolution. We elaborated response trajectories in relation to the course of depressive symptoms. Results: 159 participants were included (93% women), with an average age of 43 years old. The most frequently reported risk conditions for MDD were social isolation or poor support network and having witnessed domestic violence during childhood. Twelve response trajectories were obtained from a total of 16 possible patterns. Differences were observed when analyzing the therapeutic responses between weeks 0 and 12 and 0 and 20. The most frequent trajectories were the maintenance or worsening of depressive symptoms (37.7%). Conclusions: The results show a symptomatic variability during the course of MDD. In this five-month follow-up, more than a third of the participants did not improve their depressive symptoms.

RESUMO

Fear of contagion, together with the consequences of mitigation strategies, are often cited as causes of high levels of anxiety in the general population in the context of the COVID-19 pandemic. However, it is unclear whether published reports make it possible to distinguish between normal and pathological anxiety. We conducted a non-systematic, descriptive literature review on observational studies reporting the prevalence or frequency of anxiety symptoms in non-clinical settings published between July and December 2020. Seventy-six studies were included. Two were conducted through telephone contact while the remainder were conducted on the internet. Factors associated with greater presence/severity of anxiety symptoms were sociodemographic variables (e.g., age, gender, employment, place of residence, living conditions, marital status, and educational level). Thirty publications (39.4%) reported data on a comparison group, including samples of general populations from different geographic regions or in different periods. Only 16 studies (21%) included some estimation of the functional impairment of detected anxiety symptoms. Only seven of the studies that estimated functional impairment had comparison groups. None of the studies included in this review contain sufficient contextual or descriptive information to determine whether the reported high levels of anxiety are normal reactions of subjects in high-stress situations or actual psychiatric disorders.


El temor al contagio, junto con las consecuencias de las estrategias de mitigación, suelen citarse como causas de los altos niveles de ansiedad en la población general en el contexto de la pandemia de COVID-19. Sin embargo, no es claro si los informes publicados permiten una distinción entre la ansiedad normal y la patológica. Se realizó una revisión de la literatura no sistemática y descriptiva de los estudios observacionales que analizaron la prevalencia o la frecuencia de los síntomas ansiosos en contextos no clínicos publicados entre julio y diciembre de 2020. Se incluyeron setenta y seis estudios. Dos se realizaron mediante contacto telefónico con los participantes y el resto a través de internet. Los factores asociados a una mayor presencia/gravedad de los síntomas ansiosos fueron las variables sociodemográficas (e.g., edad, género, ocupación, lugar de residencia, condiciones de vida, estado civil y nivel educativo). Treinta publicaciones (39,4%) informaron datos sobre grupos de comparación, incluidas muestras de la población general de diferentes regiones geográficas o en diferentes períodos. Solo 16 estudios (21%) incluyeron alguna estimación de la alteración funcional asociada a los síntomas ansiosos. Solo siete de los estudios que estimaron la alteración funcional incluyeron grupos de comparación. Ninguno de los estudios incluidos en esta revisión contiene suficiente información contextual o descriptiva para determinar si los altos niveles de ansiedad son reacciones normales de personas en situaciones de alto estrés o trastornos psiquiátricos per se.

RESUMO

Electroconvulsive therapy (ECT) has multiple uses in psychiatry, but its mechanisms of action (MA) in patients with schizophrenia (PS) are poorly understood. We synthesize and discuss the available evidence in this regard. We conducted a search for primary human studies and systematic reviews searching MA of ECT in PS published in PubMed/Medline, SciELO, PsycInfo, and the Cochrane Library, including 24 articles. Genetic findings are scarce and inconsistent. At the molecular level, the dopaminergic and GABAergic role stands out. The increase in brain derived neurotrophic factor (BDNF) after ECT, is a predictor of positive clinical outcomes, while the change in N-acetyl aspartate levels would demonstrate a neuroprotective role for ECT. This intervention would improve inflammatory and oxidative parameters, thereby resulting in a symptomatic improvement. ECT is associated with an increase in functional connectivity in the thalamus, right putamen, prefrontal cortex and left precuneus, structures that play a role in the neural default mode network. A decrease in connectivity between the thalamus and the sensory cortex and an enhanced functional connectivity of the right thalamus to right putamen along with a clinical improvement have been reported after ECT. Moreover a volumetric increase in hippocampus and insula has been reported after ECT. These changes could be associated with the biochemical pathophysiology of schizophrenia. Most of the included studies are observational or quasi-experimental, with small sample sizes. However, they show simultaneous changes at different neurobiological levels, with a pathophysiological and clinical correlation. We propose that the research on ECT should be carried out from neurobiological dimensions, but with a clinical perspective.

RESUMO

BACKGROUND: Both perfectionism and social anxiety have been described in patients with eating disorders (ED) and medical students. Academic stress also can increase the risk of developing ED. AIM: To analyze the dimensions of perfectionism, social anxiety, and academic stress associated with the risk of developing ED in female medical students. MATERIAL AND METHODS: The Multidimensional Perfectionism Scale, the Liebowitz Social Anxiety Scale, the SISCO academic stress inventory and the Eating Attitudes Test-26, were applied to 163 female medical students from all levels of the career. The groups with and without risk of ED were compared according to these variables. Results: Twenty-four percent of respondents were at risk of ED. There were significant differences between scores of perfectionism, social anxiety, and academic stress between respondents with and without risk for ED. In general, there was a significant correlation among the variables. In a multivariate analysis, the predictors of ED risk were the perception of academic stress (Odds ratio (OR) 1.09; 95% confidence intervals (CI) 1.03-1.16) and personal standards in the context of perfectionism (OR 1.16; 95% CI 1.06-1.27). CONCLUSIONS: A substantial proportion of female medical students were at risk for ED. The risk of ED was determined mainly by academic stress and personal standards in the context of perfectionism. In this sample, social anxiety did not play a relevant role.

RESUMO

RESUMEN: La toma de decisiones está influenciada por múltiples factores muchas veces no conscientes. En este artículo se sintetizan algunos correlatos neurobiológicos del componente afectivo y social sobre la toma de decisiones, incluyendo el impacto del estrés agudo y crónico y la perspectiva cognitiva de las heurísticas y los sesgos en la práctica clínica. A nivel afectivo, la hipótesis del marcador somático ha asociado la respuesta corporal periférica con estructuras nerviosas centrales en la configuración de las decisiones; intervienen estructuras como la corteza orbitofrontal y el hipocampo. En la toma de decisiones sociales se involucran las dimensiones recompensa y motivación. En este tipo de decisiones es crucial la capacidad de mentalizar a otro e integrar su perspectiva en la toma de decisiones. Esta función se ha relacionado con el surco temporal posterosuperior, la unión temporoparietal, la corteza cingulada anterior y la corteza prefrontal medial. No obstante, en la toma de decisiones sociales también se integra el cumplimiento de normas socialmente establecidas. El estrés agudo o crónico puede afectar la toma de decisiones, positiva o negativamente. En estos procesos se han involucrado al eje hipotálamo-hipófiso-adrenal junto con circuitos corticoestriados, prefrontales, amigdalinos e hipocampales. En la toma de decisiones clínicas se conjugan factores "prerreflexivos" emocionales, sociales y cognitivos que influyen directamente en las conductas adoptadas con los pacientes. Recomendamos enfatizar la investigación en esta área y fortalecer su enseñanza para reconocerlos adecuadamente.


ABSTRACT Decision-making is influenced by multiple unaware factors. We synthesize some neurobiological correlates of the affective and social components on decision-making, including the impact of acute and chronic stress. We also address the impact of heuristics and biases on clinical practice from the cognitive perspective. At an affective level, the hypothesis of the somatic marker has associated the peripheral body response with central nervous structures in the configuration of decisions; structures such as the orbitofrontal cortex and the hippocampus intervene. The reward and motivation dimensions are involved in social decision-making. In these types of decisions, the ability to mentally engage others and integrate their perspective into decision making is crucial. This function has been related to the posterior superior temporal sulcus, the temporoparietal junction, the anterior cingulate cortex, and the medial prefrontal cortex. However, compliance with socially established norms is also integrated into social decision-making. Acute or chronic stress may affect decision-making, positively or negatively. The hypothalamic-pituitary-adrenal axis has been involved in these processes together with corticostriatal, prefrontal, amygdala and hippocampal circuits. In clinical decision-making, "pre-reflective" emotional, social and cognitive factors are combined, influencing the decisions towards patients. We recommend emphasizing research in this field and strengthening education in this area to recognize these aspects adequately.

RESUMO

Resumen Introducción: la desensibilización y reprocesamiento por movimientos oculares (EMDR) tiene abundante evidencia de eficacia en desórdenes del espectro traumático. Su eficacia en trastornos ansiosos (TA) y depresivos (TD) en niños, niñas y adolescentes ha sido escasamente estudiada. Método: se realizó una revisión narrativa para describir la evidencia disponible sobre eficacia de EMDR en TA y TD en población infantojuvenil. Se buscaron artículos disponibles en PubMed/Medline, SciELO, PsycINFO y Cochrane Library. Se incluyeron todos los artículos primarios y secundarios que evaluaron el efecto de EMDR en TA y TD en población infantojuvenil. Se revisaron sus referencias como segundo método de inclusión. Resultados: se identificaron nueve estudios (cinco en TA y cuatro en TD); tres fueron observacionales y seis experimentales. Todos tuvieron tamaños muestrales reducidos. En TA, los estudios corroboraron la eficacia de EMDR sobre el temor fóbico en fobia a las arañas, pero no sobre la conducta evitativa, donde sería superior la exposición in vivo. Dos series de casos expusieron la utilidad de EMDR en fagogobia y en TA asociados a epilepsia. En TD, EMDR fue eficaz en la reducción de sintomatología depresiva en el contexto del trastorno depresivo mayor, trastorno de estrés agudo y trastornos conductuales. EMDR fue comparable a terapia cognitivo-conductual. Conclusiones: la evidencia corrobora la eficacia de EMDR en TA y TD en niños, niñas y adolescentes. Sin embargo, es muy escasa y cuenta con limitaciones metodológicas. Es necesario realizar estudios experimentales con protocolos estandarizados y especializados de EMDR para TA y TD en población infantojuvenil.


Introduction: Eye movement desensitization and reprocessing (EMDR) has abundant evidence of efficacy in traumatic spectrum disorders. Its efficacy in anxiety disorders (AD) and depressive disorders (DD) in children and adolescents has been scarcely studied. Methods: We conducted a narrative review to describe the available evidence on the efficacy of EMDR in AD and DD in children and adolescents. We searched for articles available in PubMed/Medline, SciELO, PsycInfo and the Cochrane Library. All primary and secondary studies evaluating the effect of EMDR on AD and DD in children and adolescents were included. Their references were reviewed as a second method of inclusion. Results: nine studies were identified (five in AD and four in DD); three were observational and six experimental. All had small sample sizes. In AD, studies corroborated the efficacy of EMDR on phobic fear in spider phobia, but not on avoidance behavior, where in vivo exposure would be superior. Two case series reported the efficacy of EMDR in choking phobia and AD associated with epilepsy. In DD, EMDR was effective in reducing depressive symptomatology in the context of major depressive disorder, acute stress disorder, and conduct disorders. EMDR was comparable to cognitive behavioral therapy. Conclusions: The evidence corroborates the efficacy of EMDR in AD and DD in children and adolescents. However, it is very scarce and has methodological limitations. It is necessary to carry out experimental studies with standardized and specialized EMDR protocols for AD and DD in the child and adolescent population.

RESUMO

Resumen La pandemia por coronavirus, agente etiológico de la enfermedad por coronavirus 2019 (COVID-19), ha tenido consecuencias sanitarias, socioeconómicas y psicosociales que se asocian a mayores niveles de ansiedad, estrés y a alteraciones emocionales en la población general. Se presume un aumento en el consumo de sustancias en la población general, como también en el consumo problemático. En efecto, las personas con trastorno por uso de sustancias constituyen una población más vulnerable a los impactos de la pandemia, sobre todo en condiciones de confinamiento. Se realizó una búsqueda sistemática en las principales bases de datos sobre el impacto de la pandemia de COVID-19 sobre el consumo de sustancias, presentando una síntesis narrativa de la evidencia disponible en función de las principales sustancias abordadas por las publicaciones. Se discuten las tendencias en el consumo de alcohol, tabaco, opioides y cannabis, así como las recomendaciones en cuanto al seguimiento y acompañamiento terapéutico. En general, el nivel de evidencia de los artículos incorporados es bajo, ya que corresponden a opiniones de expertos y estudios observacionales exploratorios. Gran parte de las conclusiones provienen de la extrapolación de los datos obtenidos durante los brotes infecciosos de las formas previas de coronavirus. Sugerimos la realización de estudios primarios sobre consumo de sustancias y el mantenimiento de la vigilancia clínica en el periodo posterior a la pandemia en la población de personas con trastornos por uso de sustancias.


The coronavirus pandemic, the etiologic agent of coronavirus disease 2019 (COVID-19), has had sanitary, socioeconomic and psychosocial consequences associated to greater levels of anxiety, stress and emotional alterations on general population. An increase in substance consumption in the general population is presumed, as well as problematic consumption. In this line, people with substance use disorder constitute a more vulnerable population to the impact of the pandemic, especially in lockdown. We conducted a systematic search in the main databases about the impact of COVID-19 pandemic on substance consumption, performing a narrative synthesis of the available evidence based on the main substances addressed by the publications. We discuss the trends of alcohol, tobacco, opioids and cannabis consumption, and the recommendations regarding follow-up and therapeutic support. Mostly, the level of the evidence of the articles included is low, since they correspond to expert opinions and exploratory observational studies. Most of the conclusions derive from the extrapolation of data obtained during infectious outbreaks of previous forms of coronavirus. We suggest conducting primary studies on substance consumption and maintaining the clinical surveillance of people with substance use disorders in the post-pandemic period.

RESUMO

Resumen La mayoría de las técnicas de evaluación de la imagen corporal se han focalizado en el análisis de sus componentes perceptivo y subjetivo, existiendo escasa evidencia sobre la utilización del método figurativo con siluetas corporales. Describir los instrumentos que estiman la distorsión perceptual de la imagen corporal, particularmente ante la exposición de siluetas estandarizadas que varían en su corpulencia y características físicas, analizando el rol de este tipo de medidas en estudios clínicos, demográficos y transculturales. Se realizó una búsqueda bibliográfica sobre la evaluación por medio de siluetas de la distorsión de la imagen corporal mediante las bases de datos Medline/PubMed, SciELO y textos especializados. El análisis mostró que las escalas de siluetas poseen ventajas y limitaciones. Principalmente facilitan la administración rápida y la recolección de datos grupales en contextos de prevención primaria; sin embargo, son escasos los estudios de validación y su confiabilidad es parcial en muestras hispano-parlantes. Se concluyó que son necesarios más estudios poblacionales de validación, preferentemente de las escalas ya validadas a nivel internacional, que permitan incrementar la evidencia de validez y confiabilidad en la investigación de la distorsión de la imagen corporal para grupos hispanos.


Abstract Most of body image assessment techniques have focused on the analysis of their perceptual and subjective components, and there is scant evidence on the utilization of figurative methods with body silhouettes. To describe instruments that estimate the perceptual distortion of body shape, particularly when exposing standardized silhouettes that vary in their corpulence and physical characteristics, analysing the role of this type of measures in clinical, demographic and transcultural studies. A review ofspecialised textbooks and the available literature on the assessment of body image distortion through silhouettes in Medline/PubMed and SciELO was carried out. The analysis showed that silhouettes scales have advantages and limitations. They usually facilitate a fast administration and group data collection in primary prevention contexts; however, validation studies are scarce and their reliability is partial in Spanish-speaking samples. It was concluded that more validation within population studies are needed, primarily from scales already validated at an international level, that allow increasing the evidence of validity and reliability in the research of body image distortion for Hispanic groups.

RESUMO

ABSTRACT Background: The importance of foods or food constituents in mental health is increasingly recognized, and "nutritional psychiatry" is a growing discipline. Objective: This narrative review aims to present work supporting associations between food or food constituents and mental health, specifically depressive disorders. Methods: The data presented is derived from preclinical and clinical work, including in vitro and in vivo assays, as well as observational studies and randomized clinical trials of dietary interventions. The focus of the review is the mediation of inflammatory processes and oxidative stress by dietary constituents that are an integral part of a healthy diet, such as the Mediterranean diet and similar. Results and Discussion: We present evidence for the role of the diet in prevention and management of depressive disorders, beyond the effect of individual nutrients. The findings indicate that among the dietary components with higher degree of evidence to influence depressive disorders are long chain n-3 polyunsaturated fatty acids (EPA and DHA), and various dietary bioactive compounds, especially plant-derived secondary metabolites represented by polyphenols such as flavonoids and resveratrol. Conclusion: Diet exerts an important role on mental health, and evidence indicates that some dietary constituents contribute to the prevention of depressive disorders.

RESUMO

Resumen Introducción: El suicidio es una problemática de salud pública global. A nivel regional, el análisis de las dimensiones psicopatológicas y sociodemográficas del intento de suicidio (IS) son escasas. Método: estudio transversal que analizó psicopatológica y sociodemográficamente a adultos hospitalizados por IS en un hospital público de Chile. Los participantes se caracterizaron sociodemográficamente y clínicamente, evaluando síndromes neuropsiquiátricos, trastornos de la personalidad y niveles de desesperanza, impulsividad, intencionalidad, letalidad y agresividad del IS. Se aplicó estadística no paramétrica. Resultados: 45 participantes fueron incluidos, con una mediana de 39 años de edad. La mayoría residió en zonas urbanas, pertenecía a un nivel socioeconómico bajo, eran solteros, presentó algún evento vital estresante y antecedente de IS. El método de IS más frecuente fue la ingesta medicamentosa. Los diagnósticos más frecuentes fueron trastorno por consumo de alcohol y personalidad límite. En la mitad de los casos la desesperanza fue leve o inexistente. La letalidad se correlacionó positiva y significativamente con la intencionalidad suicida, así como la impulsividad con la agresividad. El antecedente familiar de IS y el trauma psíquico fueron significativamente mayores en mujeres y el dolor crónico en hombres. Los casos graves mostraron altos niveles de desesperanza, intencionalidad y letalidad, mientras que la impulsividad fue significativamente menor que en los casos no graves. En este grupo, el diagnóstico más frecuente fue episodio depresivo. Conclusiones: La muestra analizada mostró características psicopatológicas y sociodemográficas distintivas. La letalidad y la intencionalidad del IS deben ser sistemáticamente evaluadas. Los casos graves de IS mostraron características psicopatológicas diferenciales.


Introduction: Suicide is a global public health problem. At the regional level, the analysis of the psychopathological and sociodemographic dimensions of suicide attempt (SA) are scarce. Methods: We conducted a cross-sectional study to analyze psychopathological and sociodemographic characteristics of adults hospitalized for SA in a public hospital in Chile. We describe participants according to sociodemographic and clinical characteristics, appraising neuropsychiatric syndromes, personality disorders, and levels of hopelessness, impulsiveness, intentionality, lethality and aggressiveness of the SA. Non-parametric statistics were applied. Results: 45 participants were included, with a median of 39 years of age. The majority lived in urban areas, belonged to low socioeconomic status, were single, had some stressful life event and a history of SA. The most frequent SA method was drug intake. The most frequent diagnoses were alcohol use disorder and borderline personality. In half of the cases the hopelessness was low or inexistent. Lethality was positively and significantly correlated with suicidal intent, as was impulsivity with aggressiveness. Family history of SA and psychological trauma were significantly higher in women and chronic pain in men. Severe cases showed high levels of hopelessness, intentionality, and lethality, while impulsivity was significantly less than in non-severe cases. In this group, the most frequent diagnosis was depressive episode. Conclusions: The analyzed sample showed distinctive psychopathological and sociodemographic characteristics. The lethality and intent of the SA must be systematically appraised. The severe cases of SA showed particular psychopathological characteristics.

RESUMO

INTRODUCCIÓN: Chile tiene una política incipiente en relación con prácticas de parto humanizado y la violencia obstétrica es una materia de creciente discusión pública levantada por las mujeres. A pesar de este avance, no se han observado iniciativas para superar el conflicto. Surge la pregunta acerca de los diferentes puntos de vista de los principales actores involucrados, con el fin de identificar estrategias que contribuyan al desarrollo de políticas públicas de salud que consideren a los actores influyentes. OBJETIVO: Identificar la percepción de actores acerca del parto humanizado y la violencia obstétrica. MÉTODO: Se condujo una revisión panorámica (scoping review) que incluyó la descripción y el análisis de artículos y textos de análisis que reflejaran la visión de la comunidad científica y declaraciones de actores del sector gubernamental, social, profesional y político expresados en sitios web institucionales. Se desarrolló un análisis de contenido temático cualitativo, de naturaleza inductiva. RESULTADOS: Se incluyeron setenta documentos. La comunidad científica se visualiza alineada con las recomendaciones ministeriales de parto personalizado. Varios investigadores analizan las dificultades de implementación debido a la construcción histórica, sociocultural y económica del modelo biomédico de atención del parto predominante. Se observa convergencia entre la comunidad científica y otros actores en torno al reconocimiento de los beneficios del parto humanizado, así como acerca de la necesidad de superar obstáculos institucionales del sector de salud. No obstante, el proceso de cambio propuesto es lento y se observan resistencias entre profesionales de la salud para abordar las quejas de las mujeres frente a la violencia obstétrica y su demanda de atención de calidad. Esta situación se refleja a nivel parlamentario. CONCLUSIONES: El análisis de actores identifica áreas de conflicto y de consenso, así como diversas dimensiones interactuantes que obstaculizan el avance hacia la humanización de la atención del parto. Esta estrategia amplia de análisis contribuye a la identificación de aspectos críticos a ser abordados para un desarrollo de políticas sanitarias integrales y efectivas.


INTRODUCTION: Chile has an incipient policy regarding humanized birth practices. Obstetric violence is becoming an issue in the public discussion, as brought up by women. Despite this advancement, no initiatives were observed to overcome the conflict. Questions arise from the different points of view of the main stakeholders involved. These questions help identify strategies contributing to the development of health policies that consider influencing actors. OBJECTIVES: To identify stakeholders' perceptions of humanized care in childbirth and obstetric violence. METHODS: We conducted a scoping review that included articles and analysis of texts reflecting the scientific communities' point of view. We included statements from governmental, social, professional, and political actors as expressed in institutional websites. Moreover, we performed a qualitative inductive, thematic content analysis. RESULTS: We included seventy documents. The scientific community is visualized as aligned with ministerial recommendations for personalized childbirth. Several researchers analyze the difficulties for its improvement due to the historical, socio-cultural, and economic construction of the predominantly biomedical model for birthing. Convergence is observed among the scientific community and other stakeholders in recognition of humanized birth benefits and the need to overcome institutional obstacles within the health sector. However, the progress of the proposed change is slow, and health professionals' resistance to address women's complaints towards obstetric violence and claim of quality care is observed. This discussion finds its reflection in a parliamentary discussion. CONCLUSIONS: The stakeholders' analysis reflects areas of conflict and consensus, as well as the diverse interacting dimensions that hinder the advance of humanized care in childbirth. This broad analysis strategy contributes to identifying critical aspects to be addressed in the development of integral and effective health policies.

RESUMO

Background: Attentional deficit hyperactivity disorder (ADHD) in adults is associated with borderline personality characteristics or cluster B (emotional instability), but in certain populations, such as medical students, it might be associated with cluster C traits (perfectionism, dependency, anxiety). This may be compensatory to ADHD. Aim: To analyze the association between ADHD and cluster C personality traits in medical students. Material and Methods: Biodemographic characteristics, the presence of ADHD and personality traits according to clusters A, B and C were evaluated in medical students. These characteristics were compared between students with unlikely diagnosis of ADHD (Group 1) and likely or very likely diagnosis of ADHD (Group 2). Results: We included 336 participants (44% women). A likely or very likely diagnosis of ADHD was present in 64% (Group 2). Concerning personality traits, 45% exhibited traits of cluster A, 57% of cluster B, and 67% of cluster C. Compared to their counterparts of Group 1, participants in Group 2 were more likely to have a history of psychiatric/psychological care, previous diagnosis of ADHD and traits of cluster B (37 and 68% respectively) and C (55 and 74% respectively). The odds ratio of having A, B or C traits when a likely or very likely ADHD was present, were 1.29 95% confidence interval (CI) [0.8-2.07], 3.79 95% CI [2.3-6.22] and 2.4 95% CI [1.46-3.96], respectively. Conclusions: Cluster C personality traits were frequent among medical students and were significantly associated with ADHD.

RESUMO

Los adultos mayores (AM) presentan multimorbilidad y son vulnerables a las consecuencias de la polifarmacia, incluyendo las prescripciones potencialmente inadecuadas (PPI). El objetivo del estudio fue caracteri-zar a un grupo de AM de un centro de atención primaria de Chile, conocer su terapia farmacológica y pesquisar posibles interacciones medicamentosas. Se realizó un estudio transversal que incluyó a AM del programa Más AM Autovalentes. Se aplicaron instrumentos de recolección de datos y se revisaron sus fichas clínicas, describiendo sus condiciones socioeconómicas, clínicas y uso de medicamentos. Para detectar PPI se aplicaron los criterios de Beers. Se incluyeron 18 AM (94% mujeres), la mayoría con un bajo nivel socioeconómico. Las principales enfermedades crónicas fueron cardiovasculares y endocrino-metabólicas. El 66,7% presentó polifarmacia. Las PPI se relacionaron principalmente a fármacos antidepresivos, antipsicóticos y antiinflamatorios. Las PPI se asocian especialmente a comorbilidades de patologías crónicas, lo que hace necesario monitorizar permanentemente la respuesta de los AM a la terapia administrada (AU)


Older adults (OA) exhibit multimorbidity and are vulnerable to the consequences of polypharmacy, including potentially inappropriate prescriptions (PIP). The aim of the study was to characterize a group of older adults attending a public primary health center in Chile, examine their drug therapy and detect possible PIP. We conducted a descriptive cross-sectional study, including the OA attending the More Autonomous OA Program. Data collecting instruments were applied and the clinical records were revised, describing their socio-economic and clinical conditions and the use of medicines. To detect PIP the Beers' criteria were applied. Eighteen OA (94% women) were included, most of them with low socio-economic level. The main chronic diseases were cardiovascular and endocrine-metabolic; 66.7% presented polypharmacy and PIP were mainly related to the use of antidepressants, antipsychotics and anti-inflammatory drugs. PIP are associated to the comorbidities of chronic diseases, which makes it mandatory to monitor constantly the response of OA to the administered therapy (AU)

RESUMO

INTRODUCCIÓN: La Unidad de Corta Estadía Infanto-juvenil del Hospital Psiquiátrico del Salvador (Valparaíso, Chile) y sus pacientes poseen características clínicas y sociales diferentes a las reportadas por la escasa literatura nacional al respecto. OBJETIVOS: Describir el funcionamiento la unidad, las características sociofamiliares y clínicas de sus pacientes y analizar los factores asociados a su evolución clínica. MÉTODOS: Estudio transversal que describió el universo de pacientes hospitalizados durante tres años. Las variables se recogieron desde una base de datos anonimizada. Se evaluó la evolución clínica dentro del año posterior al egreso hospitalario. RESULTADOS: El modelo de atención de la unidad presenta los componentes biomédico, psicodinámico y ecológico. Se analizaron 98 pacientes, 70,4% hombres, con edad promedio de 11,5 ± 2,3 años. Un 82,6% perteneció al nivel socioeconómico bajo y 35,7% estaba desescolarizado; 98,9% presentó disfunción familiar y 91,8% de los padres portaba alguna psicopatología. Los motivos de ingreso más frecuente fueron riesgo de hetero y autoagresión. Los diagnósticos de egreso más frecuente fueron trastornos de conducta, depresivos y del desarrollo de la personalidad. El tiempo de estadía promedio fue de 41,8 ± 31,1 días. Los fármacos más utilizados fueron antipsicóticos y estabilizadores del ánimo. Un 47% tuvo una buena evolución clínica, 27% regular y 26% insatisfactoria. El único factor que se asoció a esta última fue haber tenido prescrito un antidepresivo durante la hospitalización. El factor que consistentemente se vinculó al reingreso a lo largo de un año, fue el haber presentado trastorno por consumo de sustancias. El abandono a tratamiento se relacionó con haber presentado un trastorno de conducta al egreso hospitalario y a tener padres con antecedente de suicidio o suicidio consumado. CONCLUSIONES: El perfil de pacientes de esta unidad corresponde a pacientes de nivel socioeconómico bajo, psicopatología severa, conducta desadaptativa, disfunción familiar y frecuente psicopatología parental. El trastorno por consumo de sustancias es un factor significativamente asociado al reingreso hospitalario.


INTRODUCTION: Patients of the Short-stay Child and Adolescent Unit of the Del Salvador Psychiatric Hospital (Valparaíso, Chile) exhibit different clinical and social characteristics compared to literature reports of other national centers, although published data are scarce. OBJECTIVES: To describe the operation of the Unit, the socio-familial and clinical characteristics of its patients and analyze factors associated with their clinical evolution. METHODS: We performed a cross-sectional study to describe the patients hospitalized over a three-year period. Variables were registered in an anonymized database. Clinical evolution was evaluated over the year following hospital discharge. RESULTS: The Unit's model of care can be described as involving biomedical, psychodynamic, and ecological components. We included 98 patients, of which 70.4% were male, and the average age was 11.5 ± 2.3 years. 82.6% were of low socioeconomic status, and 35.7% did not attend school; 98.9% presented family dysfunction, and 91.8% of parents had a history of psychopathology. The most frequent reason for admission was the risk of harm to self or others. The most frequent discharge diagnoses were behavioral, depressive, and personality development disorders. The average length of stay was 41.8 ± 31.1 days. The most commonly used pharmacological agents were antipsychotics and mood stabilizers. Regarding clinical evolution in the first year post-discharge, 47% were evaluated as positive, 27% regular, and 26% unsatisfactory. The factor associated with an unsatisfactory clinical course was having had in-patient antidepressants. Re-admission during the first year post-discharge was associated with comorbid substance use disorder. Treatment noncompliance was associated with a history of behavioral disorder at hospital discharge and having parents with a history of suicide or consummated suicide. CONCLUSIONS: The patient profile is one of low socioeconomic status, severe psychopathology, maladaptive behavior, family dysfunction, and parental psychopathology. Substance use disorder is also associated with readmission.
