Perfeccionismo, estrés académico y ansiedad social en mujeres estudiantes de medicina y riesgo de padecer un trastorno alimentario: un modelo multivariado / Perfectionism, academic stress and social anxiety in female medical students and the risk for eating disorders

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.

Diet and depressive disorders

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.

Percepción de actores involucrados acerca del parto humanizado y la violencia obstétrica en Chile: una revisión panorámica / Stakeholders' perceptions of humanized birth practices and obstetric violence in Chile: a scoping review

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.

Rasgos de personalidad del grupo C y trastorno por déficit de atención en estudiantes de medicina: estudio transversal analítico

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.

Sensibilidad in vitro de cepas chilenas de Cryptococcus neoformans de origen clínico / In vitro susceptibility of Chilean Cryptococcus neoformans strains of clinical source

Resumen Introducción: Las infecciones por levaduras del género Cryptococcus afectan principalmente a pacientes con déficit de la inmunidad mediada por células. Han sido escasos los estudios de sensibilidad realizados para este género en Chile. Objetivos: Determinar la sensibilidad in vitro de Cryptococcus sp a antifúngicos de uso habitual y evaluar la concordancia esencial entre sensibilidad determinada por microdilución en caldo y por difusión en agar con tiras comerciales. Materiales y Método: Estudio descriptivo de 21 cepas aisladas desde liquido céfalo-raquídeo y sangre. Las CIM50 y CIM90 para fluconazol, voriconazol y anfotericina B se determinaron por microdilución en caldo (Sensititre Yeast One®) y por difusión en agar con tiras comerciales (MIC Test Strips). Resultados: Todas las cepas correspondieron a C. neoformans. Los rangos de CIM50 y CIM90 para cada antifúngico estudiado fueron amplios por ambos métodos. La concordancia esencial entre microdilución y difusión en agar con tiras comerciales fue de 24, 62 y 29% para fluconazol, voriconazol y anfotericina B, respectivamente. Conclusiones: La prueba de Sensititre Yeast One® y la de difusión en agar con tiras comerciales, MIC Test Strips, tienen una pobre concordancia esencial para fluconazol y anfotericina B.

Abstract Background: Cryptococcus yeast infections primarily affect immunocompromised patients. There have been few susceptibility studies conducted for this genus in Chile. Aims: To determine the in vitro susceptibility to commonly used antifungals and evaluate the concordance between susceptibility determined by microdilution in broth and commercially available strips. Methods: Descriptive study of 21 Cryptococcus strains, isolated from cerebrospinal fluid and blood. The MIC50 and MIC90 for fluconazole, voriconazole and amphotericin B was determined by broth microdilution (Sensititre Yeast One®) and by commercial drug sensitivity strips (MIC Test Strips). Results: All strains corresponded to C. neoformans. The ranges of MIC50 and MIC90 for each antifungal studied were wide by both methods. The essential agreement between Sensititre Yeast One test and strips was 24, 62 and 29% for fluconazole, voriconazole and amphotericin B, respectively. Conclusions: The Sensititre Yeast One test and MIC Test Strips exhibited poor essential concordance, especially for fluconazole and amphotericin B.

Estudio transversal de las características y factores asociados a la evolución clínica de pacientes hospitalizados en una unidad de psiquiatría infanto-juvenil pública en Chile / A cross-sectional study on the characteristics and factors associated with the clinical course of child and adolescent patients hospitalized in a public child and adolescent psychiatric unit of Chile

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.

Conceptos fundamentales de bioequivalencia y biosimilitud en la normativa chilena y controversias sobre intercambiabilidad / Chilean legislation on bioequivalence and biosimilarity and current controversies related to drug interchangeability

Los medicamentos constituyen un bien económico que forma parte del gasto público y privado y de la toma de decisiones en salud. El aseguramiento de su calidad, eficacia y seguridad resulta fundamental. Sin embargo, la variada oferta disponible en el mercado chileno, donde se reconocen productos innovadores y genéricos, constituye un escenario confuso para consumidores y proveedores en salud. En esta revisión pretendemos aclarar los conceptos de fármacos bioequivalentes (aplicable a compuestos de tamaño molecular pequeño) y fármacos biosimilares (para compuestos biológicos de mayor complejidad molecular). En ambos casos, el comportamiento en el organismo del principio activo debe ser demostrado mediante estudios realizados para este fin. Una aplicación directa del concepto de bioequivalencia es la intercambiabilidad, definida como la posibilidad de utilizar un producto de un mismo principio activo, mientras la forma farmacéutica y esquema de dosificación sean iguales. Las normas relativas a esta materia y los organismos públicos encargados, no solo debieran garantizar la seguridad y la eficacia en el intercambio entre productos, sino también aspectos relacionados con el costo, la accesibilidad a los fármacos y la implementación de una guía de homogeneización de conceptos y criterios de intercambiabilidad basados en la evidencia, lo cual impactaría en una mejor educación para los usuarios, reduciendo la asimetría de información entre el usuario y la industria. La importancia de la intercambiabilidad destaca en Chile en el contexto del Plan de Garantías Explícitas en Salud (GES) y la Ley de Protección Financiera para Diagnósticos y Tratamientos de Alto Costo en Salud (Ley Ricarte Soto). Sin embargo, no es posible garantizar que todos los productos alternativos al innovador presentes en el mercado chileno son bioequivalentes. El conocimiento disponible en esta temática puede impactar y contribuir a la toma de decisiones en los prescriptores y usuarios, así como en la elaboración de políticas públicas en torno a los productos farmacéuticos bioequivalentes y biosimilares en nuestro país.

Medicines are an economic good and a fundamental component of public and private health spending and decision-making. Assurance of their quality, efficiency, and safety is essential. In Chile, the wide variety of available drugs, including innovator products, and generics­some of which are certified as bioequivalent, while others are not­creates a potentially confusing scenario for both consumers and health providers. In this review, we intend to shed light on the concepts of bioequivalency (the standard permitting interchangeability for small-molecule drugs) and biosimilarity (the standard permitting interchangeability for biological compounds of greater molecular complexity). In both cases, how the active substance interacts with the host organism must be demonstrated by studies designed and carried out for this purpose. Interchangeability is defined as the possibility of using a product of the same active principle, as long as the pharmaceutical form and dosage scheme are the same. Regulations related to bioequivalence and biosimilarity must not only guarantee safety and efficacy when products are interchanged but also facilitate cost savings and access to medicines. Implementation of evidence-based guidelines that standardize concepts of interchangeability could lead to more educated usage and reduced information asymmetry between patients (users) and industry. Drug interchangeability is particularly relevant in two government health initiatives in Chile: the Explicit Guarantees in Health Care (GES) plan, and the Law on Financial Protection for High-Cost Diagnostics and Treatment in Health Care (also known as the "Ricarte Soto Law"). Nonetheless, it is not possible to guarantee that all alternative drug products on the Chilean market are bioequivalents of the reference product. Synthesis of the available knowledge on bioequivalent and biosimilar pharmaceutical products in Chile could facilitate and contribute to stakeholder decision-making and the development of better health policies.
