Spanish validation of the short version of the racing and crowded thoughts questionnaire (RCTQ-13).

BACKGROUND: The Racing and Crowded Thoughts Questionnaire (RCTQ-13) is the most widely used specific scale for the measurement of racing thoughts, but there is currently no Spanish version that allow the evaluation in Spanish-speaking patients. The objective of this study is to translate, adapt, and validate the RCTQ-13 in a Colombian population with affective disorders. METHODS: The questionnaire was translated and back-translated, and corrections were implemented following a pilot test to improve comprehensibility. We included patients with Bipolar I Disorder and with Major depressive disorder seen in three centers in the city of Medellín, Colombia. We evaluate structural validity with confirmatory factor analysis, internal consistency, and test-retest reliability. Construct validity was also assessed with the comparison between euthymic, maniac, and depressive episodes and the correlation with worry, rumination, and mania scales. Responsiveness was measured 1 month after the first evaluation. Based on item response theory (IRT), we also estimated item difficulty, discrimination, and fit using a generalized partial credit model. RESULTS: Two hundred fifty subjects were included. Confirmatory factor analysis revealed that the three-factor structure of the scale was appropriate. Internal consistency was adequate for the entire scale (Cronbach's alpha = 0.95, 95% CI: 0.94-0.96) and for each factor. Test-retest reliability was good (intraclass correlation coefficient = 0.82, 95%IC: 0.70-0.88). For construct validity, we observed differences between patients with different types of affective episodes, a moderate positive correlation with the Penn State Worry Scale (r = 0.55) and the Ruminative Response Scale (r = 0.42), and a low negative correlation with the Young Mania Rating Scale (r = - 0.10). Responsiveness was proved to be adequate. Under IRT, the response thresholds for the response options are organized for all items. The infit was adequate for all items and the outfit was acceptable. CONCLUSIONS: The Spanish version of the RCTQ-13 is a reliable, valid, and responsive scale and can be used for the clinical assessment of the construct of racing and crowded thoughts in patients with the spectrum of affective disorders in whom this experience can be expressed with different nuances. Further research is needed to expand the relationship with rumination and worry.

Resting-state functional nuclear magnetic resonance imaging in patients with bipolar disorder: Beyond euthymia.

INTRODUCTION: Functional nuclear magnetic resonance imaging in the resting state (R-fMRI) allows the identification of complete functional connectivity networks and the possible neuronal correlations of psychiatric disorders. The literature on R-fMRI and bipolar disorder (BD) will be reviewed, emphasising the findings in the phases of mania, hypomania and depression. METHODS: It is a narrative review of the literature in which articles were searched in PubMed and Embase, with the key words in English "bipolar disorder" AND "resting state", without limit on the date of publication. RESULTS: The studies of BD patients in the mania and hypomania phases who underwent R-fMRI show concordant results in terms of decreased functional cerebral connectivity between the amygdala and some cortical regions, which indicates that this functional connection would have some implication in the normal affect regulation. Patients in the depressive phase show a decrease in functional brain connectivity, but as there are several anatomical structures involved and neural networks reported in the studies, it is not possible to compare them. CONCLUSIONS: There is a decrease in functional connectivity in patients with BD, but current evidence does not allow establishing specific changes in specific functional brain connectivity networks. However, there are already some findings that show correlation with the patients' symptoms.

Resonancia magnética nuclear funcional en estado de reposo en pacientes con trastorno bipolar: más allá de la eutimia / Resting-state functional nuclear magnetic resonance imaging in patients with bipolar disorder: beyond euthymia

Resumen Introducción: La resonancia magnética funcional en estado de reposo (RMf-ER) permite identificar redes de conectividad funcional completas y los posibles correlatos neuronales de trastornos psiquiátricos. Se revisa la literatura sobre RMf-ER y trastorno bipolar (TB) haciendo énfasis en los hallazgos en las fases de manía, hipomanía y depresión. Métodos: Es una revisión narrativa de la literatura en la que se buscaron artículos en PubMed y EMBASE con las palabras clave en inglés "bipolar disorder" AND "resting state", sin límite en la fecha de publicación. Resultados: Los estudios de pacientes con TB en fases de manía e hipomanía sometidos a RMf-ER muestran resultados concordantes en cuanto a la disminución de la conectividad funcional cerebral entre la amígdala y algunas regiones corticales, lo cual indica que esta conexión funcional tendría alguna implicación en la regulación normal del afecto. Los pacientes en fase depresiva muestran disminución en la conectividad funcional cerebral, pero como son varias las estructuras anatómicas implicadas y las redes neuronales reportadas en los estudios, no es posible compararlos. Conclusiones: Hay disminución en la conectividad funcional en los pacientes con TB, pero la evidencia actual no permite establecer cambios específicos en redes de conectividad funcional cerebral puntuales. Sin embargo, ya hay algunos hallazgos que muestran correlación con la clínica de los pacientes.

[Factors associated with the intensity of anxiety and depression symptoms in health workers of two centres of reference for COVID 19 patient care in Antioquia, Colombia - a latent class analysis]. / Factores asociados con la intensidad de los síntomas ansiosos y depresivos en personal de salud de dos centros de referencia para la atención de pacientes con COVID-19 de Antioquia, Colombia. Un análisis de clases latentes.

Objective: To classify the staff of two reference institutions for COVID-19 care in Antioquia according to the intensity of anxiety and depression symptoms, and to determine the factors associated with these classes.Methods:Cross-sectional study in which the GAD-7, PHQ-9, fear of COVID-19, and the Copenhagen Burnout scale were used. Latent class analysis was performed to identify the classes, and the factors associated with these were determined using multinomial logistic regression.Results: 486 people participated. The three-class model had the best fit: class I with low scores on the scales; class II with mild degrees of anxiety and depression, and intermediate levels of fear of COVID-19 and perceived stress; and class III with moderate and severe degrees of anxiety, depression, and perceived stress. The factors associated with belonging to class III were age (OR=0.94; 95%CI, 0.91-0.96), change of residence to avoid exposing relatives (OR=4.01; 95%CI, 1.99-8.09), and a history of depressive disorder (OR=3.10; 95%CI, 1.27-7.56), and anxiety (OR=5.5; 95%CI, 2.36-12.90). Factors associated with class II were age (OR=0.97; 95%CI, 0.95-0.99), history of depressive disorder (OR=3.41; 95%CI, 1.60-7.25), living with someone at risk of death from COVID-19 (OR=1.86; 95%CI, 1.19-2.91), family member being healthcare staff (OR=1.58; 95%CI, 1.01-2.47), and change of residence to avoid exposing relatives (OR=1.99; 95%CI, 1.11-3.59).Conclusions: Three classes of participants were obtained, two of them with anxiety and depression symptoms. Younger age and a history of mental disorder were factors associated with the two classes of symptomatic patients; other factors may be causes or consequences of the symptoms.

Validation of the Self Stigma of Seeking Help (SSOSH) scale in a population of Colombian medical students.

OBJECTIVE: Validate the Self Stigma Of Seeking Help (SSOSH) scale in a population of students of a medical school for its use in Colombia. METHODS: We included 384 medical students from the city of Medellín. Initially, two direct translations were made, two back translation and one pilot test. The internal consistency, test-retest repeatability and structural, convergent, divergent and discriminative construct validity were then evaluated. RESULTS: A easy-to-understand and to fill out Spanish version was obtained. The internal consistency of the scale was adequate (Cronbach's alpha = .80; 95%CI, .77-.83) as well as the test-retest repeatability (CCI = .77; 95%CI, .63-.86). The Confirmatory Factor Analysis showed a good fit with the one-dimensional structure (RMSEA = .073; IC90%, .056-.089; CFI = .968; TLI = .977; WRMR = .844). The convergent validity was supported by the correlation with the Public Stigma scales (ρ = .39) and Attitudes towards Seeking Help (ρ = -0.50) and the divergent validity with the Social Desirability scale (ρ = -0,05). When examining the discriminative validity, differences were found between the scores of those who would be willing to seek professional help when having a mental health problem and those who probably would not (Difference of means = 4.9; 95%CI, 2.99-6.83). CONCLUSIONS: The Colombian version of the SSOSH is valid, reliable and useful for the measurement of the Self-stigma associated with seeking professional help in the university population of the Colombian health sector. Its psychometric properties must be investigated in populations of other programs and outside universities.

Neuropsychological Aspects of Bipolar Disorder. / Aspectos neuropsicológicos del trastorno afectivo bipolar.

Bipolar disorder (BD) is a chronic condition with serious consequences on the health and functionality of patients who suffer from it, with a high heritability and segregation, and a prevalence of between 1% and 2%. Neuropsychological deficits have been implicated as a very important issue related to BD prognosis, so a review was conducted of these deficits, the related factors and their functional consequences. It has been determined that the presence of neuropsychological deficits can vary in patients with BD according to their mood state, with a great influence of depressive symptoms on the cognitive variability of patients with respect to the general population and differences with respect to patients in the manic phase. In euthymic patients, the most affected cognitive domains are those of memory, attention, and executive function, associated with a more severe disease, sociodemographic vulnerability factors, and stable over time. A relationship has been found between poor cognitive performance, especially executive dysfunction, and objective functional deficit. Furthermore, cognitive differences have been outlined between BD and other serious mental illnesses that are described in the review.

However, there are already some findings that show correlation with the patients' symptoms.

Gliomas triple negativo / Triple-negative gliomas

Los gliomas son los tumores más comunes entre las neoplasias primarias del Sistema Nervioso Central. LaOrganización Mundial de la Salud propone un sistema para su clasificación en cuatro grados crecientes demalignidad, teniendo en cuenta algunos rasgos histológicos. Sin embargo, esta clasificación supone varias limitacionesque afectan la conducta terapéutica y dificultan la predicción pronóstica. Estudios recientes han confirmadoel valor pronóstico de alteraciones moleculares específicas, demostrando que la clasificación molecularpredice la supervivencia de forma más precisa que el estudio histológico. De estas, las más emblemáticas sonla deleción 1p19q y las mutaciones en los genes que codifican para IDH1 y TP53. Las mutaciones en los genesIDH1/2 (80% de los gliomas difusos de grado II), la codeleción 1p19q (70% de los oligodendrogliomas) y lasmutaciones en TP53 (60% de astrocitomas difusos) constituyen marcadores de mayor supervivencia, por locual deben comprobarse rutinariamente en los pacientes con estos tumores como marcadores de pronóstico...

Among the primary neoplasms of the central nervous system, gliomas are the most common. The tumourclassification system proposed by the World Health Organization assigned four grades of increasing malignancyto gliomas based on some histological features. However, this classification has several limitations, one ofwhich is the poor prognostic prediction which affects the therapeutic approach. Recent studies have shown theprognostic value of specific molecular alterations. The most representative of these are the 1p19q deletion andmutations of the genes encoding IDH and TP53. Mutations of IDH1/2 (80% of low-grade diffuse gliomas,grade II), the 1p19q deletion (70% of oligodendrogliomas) and mutations of TP53 (60% diffuse astrocytomas)are associated with better survival. These three immunohistochemical markers greatly contribute to theclassification of gliomas and must be checked routinely as prognostic markers...

[Factors Associated With the Temporary Abandonment of Treatment for Disorders Due to Substance Abuse in an Institution in Medellin, Colombia]. / Factores asociados al abandono temprano del tratamiento de trastornos por uso de sustancias en una institución de Medellín, Colombia.

OBJECTIVE: To determine the frequency and factors associated withtreatment drop-out in patients from a Substance User Treatment Center in Medellín, Colombia. METHODS: A case-control study was conducted, with patients with an early treatment dropout as cases, and patients who completed the treatment as controls. Demographic data, substance use pattern, concomitant diseases, and the decision to initiate treatment were compared between cases and controls. RESULTS: The frequency of early drop-out was 59%, but a high proportion of this drop-out (47.5%) occurred in the transition period between the program stages. The variables associated with drop-out were: psychotic disorder (OR=0.32; 95% CI, 0.11-0.91), bipolar disorder (OR=0.31; 95% CI, 0.12-0.77), heroin as the principal substance compared to alcohol (OR=6.68; 95% CI, 1.52-29.4), decision to initiate the treatment by the family compared to personal decision (OR=3.02; 95% CI, 1.28-7.17), and previous treatments (OR=1.87; 95% CI, 1.02-3.44). CONCLUSIONS: The drop-out frequency is similar to those reported in other studies. Associated factors were found, which could be considered in order to plan strategies to improve the program results.

Asociación de esquizofrenia y sus dimensiones clínicas con el gen NOS1AP en población colombiana / Association of schizophrenia and its clinical implications with the nos1ap gene in the colombian population

Introducción: El gen NOS1AP codifica para la proteína adaptadora de óxido nítrico sintasa neuronal 1, que posiblemente está implicada en la etiopatogénesis de la esquizofrenia. Objetivos: Determinar si existe asociación de variantes en el gen NOS1AP con esquizofrenia y si estas variantes tienen relación con las dimensiones clínicas del trastorno en población colombiana. Metodología: Es un estudio de casos y controles, con 255 sujetos por grupo. Se tipificaron marcadores dentro del gen NOS1AP y otros informativos de origen genético, con el fin de ajustar por estratificación de la población. Se hizo un análisis factorial de componentes principales de cada uno de los ítems de las escalas de evaluación de síntomas negativos (SANS) y de síntomas positivos (SAPS) para determinar las dimensiones clínicas. Posteriormente, se evaluó la asociación de las variantes genéticas con la esquizofrenia y con cada una de las dimensiones. Resultados: Se encontró asociación entre el genotipo C/C del marcador rs945713 con esquizofrenia (OR = 1,79, IC95%: 1,13-2,84). El genotipo C/C de rs945713 se asoció con puntuaciones más altas en la dimensión “aplanamiento afectivo y alogia” y el genotipo A/A del marcador rs4657181 se relacionó con puntuaciones más bajas en esa misma dimensión. Conclusiones: Se encontró asociación significativa de marcadores dentro de NOS1AP con esquizofrenia y la dimensión clínica “aplanamiento afectivo y alogia”. Estos resultados son consistentes con estudios previos y apoyan la posibilidad de que NOS1AP influya en la susceptibilidad a esquizofrenia y que sea un modificador de sus características clínicas…

Introduction: The nitric oxide synthase 1 adaptor protein (NOS1AP) gene is possibly implicated in schizophrenia etiopathogenesis. Objective: To determine the association of NOS1AP gene variants with schizophrenia and the relationship of variants with the clinical dimensions of the disorder in the Colombian population. Methodology: It is a case-control study with 255 subjects per group. Markers within the NOS1AP gene were typified as well as other informative material of genetic origin so as to adjust by population stratification. A factorial analysis of the main components for each item in the Scales for Evaluating Negative Symptoms (SENS) together with the Scales for Evaluating Positive Symptoms (SEPS) to determine clinical dimensions. Results: Association between the C/C genotype of the rs945713 marker with schizophrenia (OR = 1.79, 95% CI: 1.13 – 2.84) was found. The C/C genotype of the rs945713 was related to higher scores in the “affective flattening and alogia” dimension; and the A/A genotype of the rs4657181 marker was associated to lower scores in the same dimension. Conclusions: Significant associations of markers inside the NOS1AP gene with schizophrenia and the “affective flattening and alogia” clinical dimension were found. These results are consistent with previous studies and support the possibility that NOS1AP influences schizophrenia susceptibility. Furthermore, NOS1AP might be a modifier of schizophrenia clinical characteristics…

Exploring epistasis in candidate genes for antisocial personality disorder.

OBJECTIVE: To identify and characterize high-order gene-to-gene interactions in antisocial personality disorder (ASPD). METHODS: Participants for case-control study were selected from the inmate male population in Bellavista prison from Medellin. The study included 310 individuals with ASPD and 200 with no ASPD. Diagnoses were made according to a best-estimate procedure based on a semistructured interview (diagnostic interview for genetic studies 3.0). We genotyped some single-nucleotide polymorphisms in candidate genes with main serotonin pathway effects. The gene-gene interaction was examined using the multifactor dimensionality reduction method version 2.0.α. We assessed model sizes of 2 and 3 loci and counted the number of replicates that contained the causal loci in the final best model that was identified using 10-fold cross validation. RESULTS: We find epistatic interaction with catechol-O-methyl transferase (COMT), tryptophan hydroxylase, and 5-HTR2A (serotonin receptor) with ASPD. This data supports an important role of polymorphism in serotonin receptors and low enzyme activity of COMT for susceptibility to ASPD. CONCLUSION: This study suggests that gene interactions between genetic variants in COMT, 5-HTR2A and tryptophan hydroxylase gene would be associated with ASPD and influence the dopamine rewards pathways and modulate serotonin levels in ASPD.

Identificación empírica de subtipos clínicos de esquizofrenia / Empirical Identification of Schizophrenia Subtypes

Introducción: Identificar empíricamente subtipos de esquizofrenia con base en síntomas presen tados a lo largo del trastorno y determinar si existen entre éstos diferencias en características sociodemográÀcas y clínicas. Métodos: Se obtuvo información clínica de 217 sujetos con esquizofrenia aplicando la Entrevista Diagnóstica para Estudios Genéticos (DIGS). Los ejes de síntomas clínicos de esquizofrenia se identificaron usando análisis de correspondencias múltiples y con base en éstos se hizo una clasificación jerárquica, para determinar los subtipos de individuos con esquizofrenia. Resultados: Se obtuvo una solución de tres ejes de síntomas clínicos: (1) delirios y alucinaciones, (2) catatónico y (3) síntomas desorganizados y negativos. Con base en éstos, se identificaron cinco subtipos: paranoide sin vivencias de influencia, desorganizado puro, catatónico, desorganizado con alucinaciones y delirios y paranoide con vivencias de influencia. Al comparar con el subtipo 1: el 2 presentó con mayor frecuencia un inicio temprano del trastorno (OR: 2,64; IC95%: 1,00-6,96) y deterioro grave (OR: 4,12; IC95%: 1,73-9,79); el 3 tenía menos comorbilidad con trastorno por uso de sustancias (OR: 0,12; IC95%: 0,01-1,00); y el 4 evidenció un mayor número de sujetos con curso continuo (OR: 4,40; IC95%: 1,84-10,52) y deterioro grave (OR: 5,34; IC95%: 2,15-13,27). No había diferencias significativas entre los subtipos 1 y 5. Conclusión: Se obtuvieron empíricamente cinco subtiposclínicos de esquizofrenia similares a descripciones previas y que tienen diferencias en el curso del trastorno y comorbilidad...

Introduction: To empirically identify subtypes of schizophrenia based on symptoms recorded during the duration of the disorder, and to determine demographic and clinical differences among subtypes. Methods: Clinical information was obtained from 217 subjects with schizophrenia by the Diagnostic Interview for Genetic Studies (DIGS). The axes of symptoms were identified using Multiple Correspondence Analysis. Based on these axes, subtypes of individuals with schizophrenia were determined by hierarchical classification analysis. Results: A solution of three axes of symptoms was obtained: (1) hallucinations and delusions, (2) catatonic, and (3) negative and disorganized symptoms. Based on these axes, subtypes were identified: Paranoid without influence experiences, disorganized, catatonic, disorganized with hallucinations and delusions, and paranoid with influence experiences. When compared with Subtype 1, Subtype 2 had a higher frequency of early onset (OR: 2.64; 95CI%: 1.00-6.96) and severe impairment (OR: 4.12; 95CI%: 1.73-9.79); Subtype 3 had a lower frequency of substance use disorders (OR: 0.12; 95CI%: 0.01-1.00); Subtype 4 had a higher number of subjects with a continuous course of the disorder (OR: 4.40; 95CI%: 1.84-10.52) and severe impairment (OR: 5.34; 95CI%: 2.15-13.27). There were not any differences between Subtypes 1 and 5. Conclusion: Five subtypes of schizophrenia were obtained which are similar to previous descriptions. The subtypes have differences in course and comorbidity...
