Aprendizaje y memoria verbal: Comparación entre pacientes con trastorno por consumo de alcohol y trastorno de depresión mayor / Learning and verbal memory: A comparison between patients with alcohol use disorder and major depressive disorder

El daño cerebral relacionado con el consumo de alcohol se asocia a alteraciones de las funciones cognitivas, entre las que destacan memoria y aprendizaje verbal. El objetivo principal es evaluar memoria y aprendizaje verbal en una muestra de 111 pacientes con trastorno por consumo de alcohol (TCA) versus 78 con trastorno de depresión mayor (TDM) y 100 controles sanos. La evaluación incluyó variables sociodemográficas y clínicas, la Escala de Hamilton para la Depresión (HDRS) y el Test de Aprendizaje Verbal de California (CVLT). Se utilizó ANOVA de un factor para comparaciones entre los 3 grupos y ANCOVAS bidireccionales incluyendo diferentes covariables. El ANOVA de un factor muestra que los pacientes con TCA y TDM obtienen puntuaciones similares entre sí e inferiores a las del grupo control (p < 0,001), con excepción del CVLT Guiado (peores puntuaciones en TDM vs TCA, p < 0,001). Tras incluir como covariables la edad, sexo y los años de estudios completados, persisten las diferencias entre los grupos de TCA y TDM frente al grupo control (p ≤ 0,003) en todos los índices con excepción del CVLT Libre Inmediato y del CVLT Guiado (peor rendimiento en TDM vs TCA, p = 0,022 y p = 0,035, respectivamente). En el segundo ANCOVA, tras controlar por gravedad de la depresión, únicamente se detectan diferencias entre los pacientes con TCA y los controles sanos (p ≤ 0,007). Los pacientes con TCA presentan una importante alteración en aprendizaje y memoria verbal al compararlos con pacientes con TDM y con personas sanas. (AU)

Brain damage related to alcohol consumption is associated with impairments in cognitive functions, among which memory and verbal learning stand out. The main objective is to evaluate memory and verbal learning in a sample of 111 patients with alcohol use disorder (AUD) versus 78 with major depressive disorder (MDD) and 100 healthy controls. The evaluation included sociodemographic and clinical variables, the Hamilton Depression Scale (HDRS) and the California Verbal Learning Test (CVLT). One-way ANOVA was used for comparisons between the 3 groups and two-way ANCOVAS including different covariates. The one-way ANOVA shows that patients with AUD and MDD had scores similar to each other and lower than those of the control group (p <0.001), with the exception of the Cued CVLT (worse scores in MDD vs AUD, p <0.001). After including age, sex and years of completed studies as covariates, the differences between the AUD and MDD groups persisted compared to the control group (p ≤ 0.003) in all indices except for the Immediate Free CVLT and the Cued CVLT (worse performance in MDD vs AUD, p = 0.022 and p = 0.035, respectively). In the second ANCOVA, after controlling for depression severity, differences were only detected between AUD patients and healthy controls (p ≤ 0.007). Patients with AUD present a significant impairment in learning and verbal memory when compared with patients with MDD and with healthy people. (AU)

Factors associated with alcohol and tobacco consumption as a coping strategy to deal with the coronavirus disease (COVID-19) pandemic and lockdown in Spain.

AIM: To provide a population-based characterization of sociodemographic and clinical risk and protective factors associated with consumption of alcohol, tobacco, or both as a coping strategy in a sample of the Spanish general population during the early phase of the COVID-19 pandemic. METHODS: Cross-sectional study based on an online snowball recruiting questionnaire. The survey consisted of an ad hoc questionnaire comprising clinical and sociodemographic information and the Spanish versions of the Depression, Anxiety, and Stress Scale (DASS-21) and the Impact of Event Scale (IES). RESULTS: The final sample included 21,207 individuals [mean age (SD) = 39.7 (14.0); females: 14,768 (69.6%)]. Up to 2867 (13.5%) of participants reported using alcohol, 2545 (12%) tobacco and 1384 (6.5%) both substances as a strategy to cope with the pandemic. Sex-related factors were associated with alcohol consumption as a coping strategy [female, OR = 0.600, p < 0.001]. However, education level, work status, and income played different roles depending on the substance used to cope. Having a current mental disorder was associated only with tobacco consumption as a coping strategy [OR = 1.391, p < 0.001]. Finally, sex differences were also identified. CONCLUSIONS: Sociodemographic, clinical, and psychological factors were associated with consumption of alcohol, tobacco, or both as a coping method for the COVID-19 pandemic and lockdown. Our findings may help develop specific intervention programs reflecting sex differences, which could minimize negative long-term outcomes of substance use after this pandemic.

Are older adults also at higher psychological risk from COVID-19?

OBJECTIVE: Given the lack of information on the psychological impact of COVID-19 on people aged ≥60, we aimed to describe their psychological responses to this pandemic and lockdown situation and compare them with those under 60 years of age. METHODS: Secondary analysis of a larger online cross-sectional study designed to determine the psychological impact of the COVID-19 pandemic and lockdown across Spain. We analyzed a total of 1690 respondents aged ≥60 years and compared them with 13,363 respondents under 60 years of age. We employed the Depression, Anxiety, and Stress Scale and the Impact of Event Scale to evaluate psychological responses. RESULTS: In all, 52.6% of women and 34.3% of men were found to be probable cases of any emotional distress (p < 0.001). In both sexes, the most common psychological response was avoidance behavior (34.7% and 23.8%, respectively), followed by depression (28.5 and 14.2%). Older women and men were considered probable cases of any emotional distress less often than younger ones (women: 52.6% vs. 72.3%, p < 0.001; men: 34.3% vs. 50.6%, p < 0.001). Finally, the results of the binary logistic regression showed that only depressive and stress responses are psychological factors associated with age group [age ≥ 60 years, O.R. = 0.617 (95% CI = 0.501 - 0.759) and 0.437 (95% CI = 0.334 - 0.573), respectively]. CONCLUSION: Contrary to our hypothesis and despite the high percentage of emotional distress we found in older adults, especially women, they are actually at lower risk of developing depressive and stress consequences from COVID-19 and lockdown than those under 60 years of age. That said, we believe our results highlight the need for expert guidance in this age group, especially older women living alone.

The Mediating Role of Impulsivity in the Relationship Between Suicidal Behavior and Early Traumatic Experiences in Depressed Subjects.

Background: Depressed patients with early traumatic experiences may represent a clinically and biologically distinct subtype, with worse clinical outcomes and greater risk of suicide. Since early traumatic experiences alter development of systems that regulate the stress response, increasing sensitivity to stress and mood disorders later in life, certain personality features may influence coping strategies, putting individuals with depression and a history of early traumatic experiences at greater risk of suicidal behavior. Objective: To determine whether impulsivity mediates the relationship between early traumatic experiences and suicidal behavior in patients with major depressive disorder (MDD). Methods: The total sample consists of 190 patients [mean age (SD) = 53.71 (10.37); females: 66.3%], with current MDD (DSM-5 criteria). The Childhood Trauma Questionnaire-Short Form (CTQ-SF), the List of Threatening Experiences (LTE), and the Barratt Impulsiveness Scale-11 (BIS-11) were used to assess childhood and adulthood adverse life events and impulsivity, respectively. We developed mediation models by bootstrap sampling methods. Results: Eighty-one (42.6%) patients had a history of previous suicide attempts (SA). CTQ-SF-Total and BIS-11-Total scores were significantly higher in MDD patients with previous SA. Correlation analyses revealed significant correlations between the CTQ-SF-Total and BIS-11-Total, CTQ-SF-Total and HDRS-Total, and BIS-11-Total and HDRS-Total scores. Regression models found that CTQ-SF-Total, BIS-11-Total, and HDRS-Total scores were associated with SA. Mediation analyses further revealed the association between CTQ-SF-Total and SA was mediated by the indirect effect of the BIS-11-Total score (b = 0.007, 95% CI = 0.001, 0.015), after statistically controlling for sex, the HDRS-Total, and the LTE-Total. Discussion: Data suggest that impulsivity could mediate the influence of childhood trauma on suicidal behavior. This will help understand the role of risk factors in suicidal behavior and aid in the development of prevention interventions focused on modifiable mediators when risk factors are non-modifiable.

Predicting real-world functioning in outpatients with schizophrenia: Role of inflammation and psychopathology.

Several studies indicate that negative and cognitive symptoms are determining factors of functioning in patients with schizophrenia. However, they do not usually include biological aspects, such as inflammatory markers. The current prospective study aims to identify clinical and biological factors predicting real-world functioning, at baseline and at one-year follow-up, of outpatients in an early stage of schizophrenia. Sample consist of 73 clinically stable patients with schizophrenia, of which 57 completed the one-year follow-up. Accurate psychopathology, functioning, and cognitive assessments were performed at baseline and follow-up (Positive and Negative Syndrome, Brief Negative Symptom, Calgary Depression, Personal and Social Performance Scales, and MATRICS Cognitive Consensus Battery). Biological biomarkers including anthropometric data and blood parameters were collected. Pearson correlation and multiple regression analyses including potential confounding factors were performed. Negative symptoms (especially asociality and avolition), along with the inflammatory biomarker interleukin-2, are the most important determining factors of poor real-world functioning in early-stage schizophrenia. The previous functioning, along with baseline cognitive performance in attention and vigilance, predicts functioning at one-year follow-up in these patients. Strategies aimed at improving negative and cognitive symptoms, as well as modifying certain inflammatory pathways, should be the targets to achieve functional recovery in the first years of schizophrenia.

Factors associated with tobacco consumption in patients with depression. / Factores asociados con consumo de tabaco en pacientes con depresión.

Smoking and depression are related in a bidirectional way: smoking is the primary avoidable cause of illness and death in patients with depression, and depression is one of the most consistent risk factors for smoking. The main objective of this study is to investigate the relationship between smoking and depression, analyzing sociodemographic and clinical variables such as severity of symptoms, subtype of affective disorder, and its impact on suicidal behavior in the clinical population.A sample of 201 patients, over 18 years of age [mean age (SD) = 53.76 (10.36) years; women = 132 (65.7%)], with a history of depressive episode (unipolar or bipolar) or dysthymia (ICD 10 criteria) was studied.Current smoking prevalence was 43.2% and life-time prevalence 61.2%. No statistically significant differences in smoking prevalence between men and women were found (X2 = 3.896, p = 0.143). The average age of onset was 17.81 (5.60) years. There was a tendency towards a linear association between number of cigarettes/day consumed and severity of depression according to the Hamilton Depression Scale (HDRS) in current smokers (Pearson's R = 0.298, p = 0.050). Multinomial logistic regression analysis showed that current tobacco consumption was associated with higher HDRS scores, with each additional point on the HDRS increasing the likelihood of smoking by 0.062 [p = 0.032; OR (95% CI) = 1.064 (1.005-1.125)].Our results showed that depressed patients present higher prevalence of current smoking than the general population, also suggesting a relationship between severity of consumption and severity of depressive symptoms.

Tabaquismo y depresión se relacionan de forma bidireccional: el tabaquismo es la primera causa evitable de enfermedad y muerte en pacientes con depresión, y la depresión constituye uno de los factores de riesgo de tabaquismo más consistentes. El principal objetivo del presente trabajo es profundizar en la relación entre tabaquismo y depresión, analizando variables socio-demográficas y clínicas como la gravedad de los síntomas, el subtipo de trastorno afectivo, y su impacto en las conductas suicidas en población clínica.Se estudió una muestra de 201 pacientes, mayores de 18 años [edad media (SD) = 53,76 (10,36) años; mujeres = 132 (65,7%)], con historia de episodio depresivo (unipolar o bipolar) o distimia (criterios CIE 10).La prevalencia de tabaquismo actual fue 43,2% y la prevalencia vida 61,2%, no existiendo diferencias estadísticamente significativas entre hombres y mujeres (X2 = 3,896; p = 0,143). La edad media de inicio fue 17,81 (5,60) años. Se observó tendencia a asociación lineal entre número de cigarrillos/día consumidos y gravedad de la depresión según la Escala de Hamilton para la Depresión (HDRS) en los consumidores actuales de tabaco (R de Pearson = 0,298; p = 0,050). El análisis de regresión logística multinomial puso de manifiesto que el consumo actual de tabaco se asocia con puntuaciones más elevadas en la HDRS, de modo que cada incremento de un punto en dicha escala, la posibilidad de fumar aumenta en 0,062 [p = 0,032; OR (95% CI) = 1,064 (1,005-1,125)].Nuestros resultados muestran que los pacientes deprimidos presentan mayor prevalencia de consumo actual de tabaco que la población general, sugiriendo además una relación entre gravedad de consumo y gravedad de los síntomas de depresión.

History of Lifetime Cannabis Use Is Associated with Better Cognition and Worse Real-World Functioning in Schizophrenia Spectrum Disorders.

BACKGROUND: Data on associations between cannabis use and psychopathology, cognition and functional impairment in schizophrenia spectrum disorders (SSD) is controversial. OBJECTIVES: To examine the effect of cannabis on psychopathology, cognition and real-world functioning in SSD patients. METHOD: Naturalistic cross-sectional study, 123 clinically stable SSD outpatients. ASSESSMENT: demographic and clinical data, psychometric evaluation: Positive and Negative Syndrome, Hamilton Depression Rating, Clinical Global Impression (CGI), Personal and Social Performance and Screen for Cognitive Impairment in Psychiatry (SCIP) scales. Patients were classified as cannabis user patients (CUP) and non cannabis user patients (NCUP) according to self-report, both lifetime and last year. STATISTICAL ANALYSIS: chi-square, Student t test, ANOVA (Duncan post hoc), and general linear model analysis for adjusting for antipsychotic doses. RESULTS: Mean age 40.75, 66.7% male, single (66.7%), prior hospital admissions 2.75, mean length of illness 13.85 years. 53.7% were lifetime cannabis users and 8.9% last year users. Lifetime CUP had more hospitalizations (p = 0.013) at a younger age (p = 0.002), and showed better cognitive functioning globally (CGI-C: p = 0.045) and on working memory and processing speed (SCIP-2: p = 0.039; SCIP-5: p = 0.033) and worse functioning in socially useful activities (p = 0.014) than NCUP. All these differences remained after adjusting for antipsychotic doses. Last year cannabis users had worse mood (Hamilton Depression Rating Scale 9.66 vs. 5.64; p = 0.002), but this difference disappears when adjusting for antipsychotic doses. CONCLUSIONS: Lifetime cannabis use is associated with better working memory and processing speed and worse real-world functioning in the area of socially useful activities in patients with schizophrenia-related disorders. Clinicians should, therefore, be aware of it to provide patient-centred care in their daily clinical practice.

Biomarcadores sanguíneos diferenciales de las dimensiones psicopatológicas de la esquizofrenia / Differential blood-based biomarkers of psychopathological dimensions of schizophrenia

La sintomatología de la esquizofrenia es heterogénea, no existiendo ningún síntoma patognomónico de la misma. Además, su diagnóstico presenta dificultades, ya que se basa en información subjetiva en lugar de en marcadores. El propósito de este estudio es ofrecer una revisión del estado actual de los biomarcadores sanguíneos de las dimensiones psicopatológicas de la esquizofrenia. En pacientes con esquizofrenia se han observado disfunciones inflamatorias, hormonales o metabólicas y se ha intentado establecer los biomarcadores responsables de esas disfunciones. La identificación de estos podría contribuir al diagnóstico y tratamiento de la esquizofrenia (AU)

Desarrollo de la versión española de la Escala Breve para la Evaluación de la Capacidad Funcional [Sp-UPSA-Brief] para pacientes con esquizofrenia y trastorno bipolar / Development of the Spanish Brief-version of the University of California Performance Skills Assessment (Sp-UPSA-Brief) in patients with schizophrenia and bipolar disorder

Introducción. En los pacientes con trastornos mentales graves, la medición de los desenlaces clínicos debería incluir como mínimo la evaluación de los síntomas, la cognición, la funcionalidad y la calidad de vida. Desde un punto de vista pragmático, los instrumentos abreviados y eficientes presentan mayor potencial en cuanto a utilidad y validez clínica. Nuestro objetivo fue desarrollar la versión española de la escala UPSA abreviada (SP-UPSA-Brief). Material y métodos. Estudio multicéntrico de diseño naturalista y con 6 meses de seguimiento. Se evaluaron 139 pacientes con esquizofrenia, 57 con trastorno bipolar y 31 controles mediante el empleo de la Sp-UPSA, la CGI-S, la GAF, y la PSP. Se realizó un modelo de regresión lineal multivariante para identificar las subescalas candidatas para la Sp-UPSA-Brief. Resultados. Según el modelo de regresión por pasos para los pacientes con esquizofrenia las subescalas de comunicación y de transporte de la Sp-UPSA fueron la primera y la segunda introducidas, con p < 0,0001 (R2 = 0,88, modelo df = 2, F = 395,05). En los pacientes con trastorno bipolar las subescalas de transporte y de comunicación de la Sp-UPSA se introdujeron en primer y segundo lugar, respectivamente, con p < 0,0001 (R2 = 0,87, modelo df = 2, F = 132,32). El alfa de Cronbach fue de 0,78 para la esquizofrenia y de 0,64 en pacientes bipolares. El test-retest fue de 0,66 y de 0,64 (p < 0,0001), respectivamente. Los coeficientes de correlación de Pearson entre la Sp-UPSA y la Sp-UPSA-Brief fueron de 0,93 para la esquizofrenia y de 0,92 para los pacientes bipolares (p < 0,0001). La Sp-UPSA-Brief discriminó entre los pacientes y los controles. En los pacientes con esquizofrenia también discriminó entre los grados de gravedad de la enfermedad de acuerdo con las puntuaciones CGI-S. Conclusiones. La escala Sp-UPSA-Brief es un instrumento alternativo, válido y fiable, para la evaluación de la capacidad funcional. Su formato abreviado lo convierte en un instrumento más útil a la hora de evaluar la capacidad funcional de los pacientes con trastornos mentales graves, sobre todo en la práctica clínica diaria (AU)

Introduction. In patients with severe mental disorders outcome measurement should include symptoms, cognition, functioning and quality of life at least. Shorter and efficient instruments have greater potential for pragmatic and valid clinical utility. Our aim was to develop the Spanish UPSA Brief scale (Sp-UPSA-Brief). Material and methods. Naturalistic, 6-month follow-up, multicentre study. 139 patients with schizophrenia, 57 with bipolar disorder and 31 controls were evaluated using the Sp-UPSA, CGI-S, GAF, and PSP. We conducted a multivariate linear regression model to identify candidate subscales for the Sp-UPSA-Brief. Results. The stepwise regression model for patients with schizophrenia showed that communication and transportation Sp-UPSA subscales entered first and second at p < 0.0001 (R2 = 0.88, model df = 2, F = 395.05). In patients with bipolar disorder transportation and communication Sp-UPSA subscales entered first and second at p < 0.0001 (R2 = 0.87, model df = 2, F = 132.32). Cronbach's alpha was 0.78 in schizophrenia and 0.64 in bipolar patients. Test-retest was 0.66 and 0.64 (p < 0.0001) respectively. Pearson correlation coefficients between Sp-UPSA and Sp-UPSA-Brief were 0.93 for schizophrenia and 0.92 for bipolar patients (p < 0.0001).The Sp-UPSA-Brief discriminated between patients and controls. In schizophrenia patients it also discriminated among different levels of illness severity according to CGI-S scores. Conclusion. The Sp-UPSA-Brief is an alternate instrument to evaluate functional capacity that is valid and reliable. Having a shorter instrument makes it more feasible to assess functional capacity in patients with severe mental disorders, especially in everyday clinical practice (AU)

MATERIAL AND METHODS: Naturalistic, 6-month follow-up, multicentre study. 139 patients with schizophrenia, 57 with bipolar disorder and 31 controls were evaluated using the Sp-UPSA, CGI-S, GAF, and PSP. We conducted a multivariate linear regression model to identify candidate subscales for the Sp-UPSA-Brief. RESULTS: The stepwise regression model for patients with schizophrenia showed that communication and transportation Sp-UPSA subscales entered first and second at p<0.0001 (R(2)=0.88, model df=2, F=395.05). In patients with bipolar disorder transportation and communication Sp-UPSA subscales entered first and second at p<0.0001 (R(2)=0.87, model df=2, F=132.32). Cronbach's alpha was 0.78 in schizophrenia and 0.64 in bipolar patients. Test-retest was 0.66 and 0.64 (p<0.0001) respectively. Pearson correlation coefficients between Sp-UPSA and Sp-UPSA-Brief were 0.93 for schizophrenia and 0.92 for bipolar patients (p<0.0001).The Sp-UPSA-Brief discriminated between patients and controls. In schizophrenia patients it also discriminated among different levels of illness severity according to CGI-S scores. CONCLUSION: The Sp-UPSA-Brief is an alternate instrument to evaluate functional capacity that is valid and reliable. Having a shorter instrument makes it more feasible to assess functional capacity in patients with severe mental disorders, especially in everyday clinical practice.

Validation of a European Spanish-version of the University of California performance Skills Assessment (Sp-UPSA) in patients with schizophrenia and bipolar disorder.

AIMS: To validate the Spanish version of the University of California Performance Skills Assessment (UPSA) in patients with severe mental disorders. METHODS: Naturalistic, 6month follow-up, multicentre, validation study. 139 patients with schizophrenia, 57 bipolar patients and 31 controls were evaluated using the following scales: Spanish UPSA (Sp-UPSA), Clinical Global Impression, Severity (CGI-S), Global Assessment of Functioning (GAF), and Personal and Social Performance (PSP). RESULTS: Reliability: Internal consistency (Cronbach's alpha) was 0.81 in schizophrenia and 0.58 in bipolar patients. Test-retest was 0.74 and 0.65 (p<0.0001) respectively. Construct validity: Pearson correlation coefficients between Sp-UPSA and PSP total scores were 0.42 (p<0.0001) for schizophrenia and 0.44 (p=0.001) for bipolar patients. For Sp-UPSA and GAF scores correlation coefficients were 0.43 and 0.52 (p<0.0001) respectively. Discriminant validity: The Sp-UPSA discriminated between patients and controls. In schizophrenia patients it also discriminated among different levels of illness severity according to CGI-S scores. In control versus patients with schizophrenia contrasts, the area under the curve was 0.89 and a cut-off point of 85 provided a sensitivity of 82.7% and a specificity of 77.4%. In bipolar patients, the area under the curve was 0.85 and a cut-off point of 90 provided a sensitivity of 82.5% and a specificity of 64.5%. CONCLUSION: The Spanish UPSA is a reliable and valid instrument for assessing functional capacity in severe mentally ill patients. It seems to be appropriate for use in clinical trials and in everyday clinical practice as a means of monitoring functional outcomes.
