    (2023) Hernández-Fleta, J. L. (J. L.); Lahortiga, F. (Francisca); Gonzalez-Pinto, A. (Ana); Sanchez-Villegas, A. (Almudena); Cabrera-Suárez, B. (B.); Vega-Pérez, R. (R.); Sayon-Orea, C. (Carmen); Molero, P. (Patricio)
    Introduction: There is substantial evidence supporting that improving diet quality leads to improved health -related quality of life (HRQoL). Our major aim was to assess the effectiveness of a Mediterranean diet-based nutritional intervention to improve HRQoL in the context of a secondary prevention trial of depression. Secondarily to assess its effectiveness among adults aged 60 or more years.Methods: The PREDIDEP study is a 2-year multicentre, randomized, single-blinded nutritional trial. At baseline and at 1-year and 2-year follow-up, SF-36 health survey questionnaire was collected to evaluate participants' HRQoL (total and specific range for each of the 8 dimensions: 0 to 100 points). Mixed effect linear models were used to assess changes in HRQoL according to adherence to the Mediterranean diet. The trial was registered at ClinicalTrials.gov NCT03081065.Results: After 2 years of intervention, the Mediterranean Diet intervention group compared to control group (without nutritional intervention, only usual clinical care) showed an improvement in some dimensions of HRQoL such as Mental Health (7.22; 95 % CI = 2.22-12.22) (between-group difference: 6.79; 95 % CI -0.14-13.73, p = 0.055); Vitality (9.51; 95 % CI = 4.00-15.03) (between-group difference: 9.00; 95 % CI 1.75-16.25, p = 0.020); Mental Summary Component (2.83; 95 % CI = 0.55-5.11) (between-group difference: 1.17; 95 % CI = -1.96-4.30, p = 0.462); and General Health (10.70; 95 % CI = 5.58-15.81) (between-group difference: 6.20; 95 % CI = -0.89-13.28, p = 0.086). Similar results were observed for participants aged 60 or more years.Conclusion: The intervention based on Mediterranean diet in patients with previous depression seems to be effective in improving HRQoL, especially the mental dimensions. This effect is also observed among participants aged 60 or more years.

    Self-perceived level of competitiveness, tension and dependency and depression risk in the SUN cohort
    (BMC, 2018) Martinez-Gonzalez, M.A. (Miguel Ángel); Raquel; Zazpe, I. (Itziar); Santiago, S. (Susana); Lahortiga, F. (Francisca); Sanchez-Villegas, A. (Almudena); Molero, P. (Patricio)
    Background: Emerging evidence suggests a possible etiologic role of certain personality traits (not necessary dysfunctional) in the risk of depression, but the longitudinal long-term available evidence is currently scarce. We longitudinally assessed whether 3 common personality traits (competitiveness, tension and dependency) were associated with the risk of depression after a maximum follow-up of 15 years. Methods: We assessed 15,604 university graduates free of depression at baseline through a self-administered questionnaire including personality traits. Simple, Likert-type, questions with 11 possible answers ranging from 0 to 10 were used at baseline to assess the 3 personality traits. We compared participants with high scores (7–10) versus those with low scores (0–4). New medical diagnoses of depression during follow-up were used as the outcome. Results: During a median follow-up of 10.1 y, we prospectively identified 902 new medical diagnoses of depression. The multivariable-adjusted hazard ratios (95% confidence intervals) for depression were 1.85 (1.52–2.24) for participants with higher baseline tension (7–10 versus 0 to 4), P-trend < 0.001; and 1.23 (1.06–1.44) for high versus low baseline dependence levels, P-trend = 0.004. Higher levels of competitiveness were marginally associated with lower risk of depression, with hazard ratio = 0.78 (0.61–1.01), P-trend = 0.105. Conclusion: A simple scoring system of personality traits shows an independent association with the future occurrence of depression. This finding underscores, with now prospective evidence, the importance of personality traits in the aetiology of depression and can provide a clinically useful tool for gathering valid information about depression-related personality traits.

    The impact of the Val158Met COMT polymorphism on context processing in patients on the schizophrenia spectrum and their relatives
    (Elsevier, 2015) Lopez-Garcia, P. (Pilar); Ortuño-Sanchez-Pedreño, F. (Felipe); Young, L. (Leslie); Marin, J. (Juan); Molero, P. (Patricio)
    Introduction: The level of dopamine in the prefrontal cortex (PFC) appears to play a fundamental role in cognitive alterations in schizophrenia. The Val158Met polymorphism of the catechol-O-methyltransferase (COMT) enzyme impacts dopamine availability in the prefrontal cortex and can thus influence cognitive functioning. Among the different cognitive deficits found in schizophrenia patients, context processing deficits have been noted as a specific characteristic of schizophrenia, for which the cerebral substrate appears to be located in the dorsolateral PFC. In this study, we examine the impact of the Val158Met COMT polymorphism on context processing in a sample of patients on the schizophrenia spectrum, their relatives, and healthy control subjects evaluated using the Dot Probe Expectancy Task (DPX). Methods: Forty patients on the schizophrenia spectrum, 26 relatives, and 63 healthy control subjects were genotyped and performed the DPX test. Results: Both patients and their relatives demonstrated deficits in context processing influenced by the Val158Met COMT polymorphism. Compared with the other subjects, the Val/Val subjects showed poorer performance on context processing tasks. Conclusions: Deficits in context processing in schizophrenic patients and their families are influenced by the Val158Met COMT functional polymorphism, likely as a consequence of reduced dopamine availability in the PFC.

    Preventing the recurrence of depression with a Mediterranean diet supplemented with extra-virgin olive oil. The PREDI-DEP trial: study protocol
    (Springer Science and Business Media LLC, 2019) Hernández-Fleta, J. L. (J. L.); Pla-Vidal, J. (Jorge); Ortuño-Sanchez-Pedreño, F. (Felipe); Florido-Rodríguez, M. (M.); Navarro, S. (Silvia); Lahortiga, F. (Francisca); Chiclana-Actis, C. (Carlos); Cabrera, C. (Carmen); Calviño-Cabada, M. J. (M. J.); Gonzalez-Pinto, A. (Ana); Almeida, Y. (Y.); Sanchez-Villegas, A. (Almudena); Cabrera-Suárez, B. (B.); Vega-Pérez, R. (R.); Molero, P. (Patricio)
    Background: The role of dietary patterns in the prevention of unipolar depression has been analyzed in several epidemiological studies. The primary aims of this study are to determine the effectiveness of an extra-olive oil enriched Mediterranean diet in reducing the recurrence of depression and improving the symptoms of this condition. Methods: Multicenter, two-arm, parallel-group clinical trial. Arm 1, extra-virgin olive oil Mediterranean diet; Arm 2, control group without nutritional intervention. Dieticians are in charge of the nutritional intervention and regular contact with the participants. Contacts are made through our web platform (https://predidep.es/participantes/) or by phone. Recurrence of depression is assessed by psychiatrists and clinical psychologists through clinical evaluations (semi-structured clinical interviews: Spanish SCID-I). Depressive symptoms are assessed with the Beck Depression Inventory. Information on quality of life, level of physical activity, dietary habits, and blood, urine and stool samples are collected after the subject has agreed to participate in the study and once a year. Discussion: To the best of our knowledge, the PREDI-DEP trial is the first ongoing randomized clinical trial designed to assess the role of the Mediterranean diet in the prevention of recurrent depression. It could be a cost-effective approach to avoid recurrence and improve the quality of life of these patients.

    Takotsubo cardiomyopathy secondary to electroconvulsive therapy in a young adult with Down syndrome regression disorder
    (2024) Ortuño-Sanchez-Pedreño, F. (Felipe); Real-de-Asua, D. (Diego); Bullard, J.P. (José Pablo); Unceta, M.M. (María del Mar); Ortega, M.C. (Maria del Carmen); Molero, P. (Patricio)
    We report the case of an 18-year-old woman with Down syndrome (DS) who developed Takotsubo cardiomyopathy (TSC) immediately after the administration of electroconvulsive therapy (ECT), a treatment prescribed for Down syndrome regression disorder resistant to oral psychotropic drugs. TSC is a nonischemic cardiomyopathy related to psychological or physical stress, which has been described as a rare complication of ECT (Kinoshita et al., 2023, Journal of Electroconvulsive Therapy, 39, 185-192). The clinical description of the case is accompanied by a discussion of the peculiarities of the autonomic nervous system in DS.

    Abstract Background: The catechol-O-methyltransferase (COMT) enzyme plays a crucial role in dopamine degradation, and the COMT Val158Met polymorphism (rs4680) is associated with significant differences in enzymatic activity and consequently dopamine concentrations in the prefrontal cortex. Multiple studies have analyzed the COMT Val158Met variant in relation to antipsychotic response. Here, we conducted a meta-analysis examining the relationship between COMT Val158Met and antipsychotic response. Methods: Searches using PubMed, Web of Science, and PsycInfo databases (03/01/2015) yielded 23 studies investigating COMT Val158Met variation and antipsychotic response in schizophrenia and schizo-affective disorder. Responders/nonresponders were defined using each study’s original criteria. If no binary response definition was used, authors were asked to define response according to at least 30% Positive and Negative Syndrome Scale score reduction (or equivalent in other scales). Analysis was conducted under a fixed-effects model. Results: Ten studies met inclusion criteria for the meta-analysis. Five additional antipsychotic-treated samples were analyzed for Val158Met and response and included in the meta-analysis (ntotal = 1416). Met/Met individuals were significantly more likely to respond than Val-carriers (P = .039, ORMet/Met = 1.37, 95% CI: 1.02–1.85). Met/Met patients also experienced significantly greater improvement in positive symptoms relative to Val-carriers (P = .030, SMD = 0.24, 95% CI: 0.024–0.46). Posthoc analyses on patients treated with atypical antipsychotics (n = 1207) showed that Met/Met patients were significantly more likely to respond relative to Val-carriers (P = .0098, ORMet/Met = 1.54, 95% CI: 1.11–2.14), while no difference was observed for typical-antipsychotic-treated patients (n = 155) (P = .65). Conclusions: Our findings suggest that the COMT Val158Met polymorphism is associated with response to antipsychotics in schizophrenia and schizo-affective disorder patients. This effect may be more pronounced for atypical antipsychotics.

    A longitudinal analysis of diet quality scores and the risk of incident depression in the SUN project
    (BioMed Central, 2015) Martinez-Gonzalez, M.A. (Miguel Ángel); Toledo, E. (Estefanía); Lahortiga, F. (Francisca); Ruiz-Canela, M. (Miguel); Henriquez-Sanchez, P. (Patricia); Sanchez-Villegas, A. (Almudena); Molero, P. (Patricio)
    Background: Some studies have pointed out that several dietary patterns could be associated with a reduced risk of depression among adults. This association seems to be consistent across countries, cultures and populations. The objective of the study was to compare and to establish the type of relationship between three diet quality scores and depression in the SUN (Seguimiento Universidad de Navarra) Cohort study. Methods: We performed a dynamic cohort study based on Spanish university graduates free of depression at baseline. Dietary intake was repeatedly assessed at baseline and after 10 years of follow-up with a validated semi-quantitative foodfrequency questionnaire. Three previously described diet quality scores: Mediterranean Diet Score (MDS), Pro-vegetarian Dietary Pattern (PDP) and Alternative Healthy Eating Index-2010 (AHEI-2010) were built. Participants were classified as having depression if they reported a new clinical diagnosis of depression by a physician or initiated the use of an antidepressant drug during follow-up. Time-dependent Cox regression models with cumulative averages of diet and restricted cubic splines were used to estimate hazard ratios of depression according to quintiles of adherence to the MDS, PDP and AHEI-2010. Results: One thousand and fifty one incident cases of depression were observed among 15,093 participants from the SUN Cohort after a median follow-up of 8.5 years. Inverse and significant associations were observed between the three diet quality scores and depression risk. The hazard ratios and 95 % confidence intervals for extreme quintiles (fifth versus first) of updated adherence to MDS, PDP and AHEI-2010 were 0.84 (0.69–1.02), 0.74 (0.61–0.89) and 0.60 (0.49–0.72), respectively. The dose–response analyses showed non-linear associations, suggesting that suboptimal adherence to these dietary patterns may partially be responsible for increased depression risk. Conclusions: Better adherence to the MDS, PDP and AHEI-2010 was associated with a reduced risk of depression among Spanish adults. However, our data suggested a threshold effect so that although the risk of depression was reduced when comparing moderate versus lower adherence, there was not much extra benefit for the comparison between moderate and high or very high adherence.

    Cigarette smoking and risk of suicide in bipolar disorder: a systematic review
    (2023) Gutierrez-Rojas, L. (L.); Girela-Serrano, B. (Braulio); Gómez-Sierra, F.J. (Francisco José); Martínez-Hortelano, A. (Alicia); García-Jiménez, J. (Jesús); Moreno-Merino, P. (Paula); Molero, P. (Patricio)
    ObjectiveBipolar disorder (BD) is a highly prevalent, chronic and recurrent mental illness. The smoking rates in patients with BD are much higher than those of the general population, and BD is associated with an increased risk of suicide. An association between smoking and suicidal behavior has been found in the general population, this systematic review examines whether there is evidence of an association between smoking and suicide behavior in patients with BD. MethodA database search was carried out in Medline, Embase, The Cochrane Library, Scopus, and Web of Science, updated until December 31st, 2021, according to the 2020 PRISMA guidelines. We identified prospective and retrospective studies that included patients diagnosed with BD types I, II, and not otherwise specified, and in which smoking and suicidal behavior were correlated. Articles that focused exclusively on other mental disorders were excluded. The Ottawa-Newcastle scale was used to assess the methodological quality of the included articles. ResultsFifteen articles (n = 7,395) met all the inclusion criteria. In nine of these articles, the authors found an association between smoking and suicidal behavior in BD, while in the remaining six articles, this association was not found. A great deal of variability was observed between articles, particularly in the measurement of suicidal behavior and tobacco consumption. The risk of bias, as assessed by the NOS, was high for most of the included articles, except for two papers, whose risk was low. ConclusionIt was not possible to establish a clear relationship between tobacco use and the risk of suicide in BD patients due to the heterogeneity of the articles included in this systematic review, which had different sample sizes and methodological issues. However, both conditions are highly prevalent and have a negative impact on the prognosis of BD. Therefore, a systematic approach is needed, based on accurate measurement of a patient's smoking habits and their risk of suicidal behavior, in order to establish an appropriate therapeutic plan. Additional informationThis research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors and was registered on PROSPERO with the CRD42022301570 on January 21th 2022.

    Aberrant timing and oddball detection in schizophrenia: findings from a signed differential mapping meta-analysis
    (Elsevier, 2018) Radua, J. (Joaquim); Solanes, A. (Aleix); Ortuño-Sanchez-Pedreño, F. (Felipe); Ortuño, M. (Marta); Garcés, M.S. (María Sol); Alustiza-Quintana, I. (Irene); Goena, J. (Javier); Molero, P. (Patricio)
    Schizophrenia (SZ) is associated with deficits in both temporal and salience processing. The underlying neurological dysfunctions in both processes, which are interrelated and share neuroanatomical bases, remain poorly understood. The principal objective of this study was to elucidate whether there are any brain regions that show abnormal response during timing and oddball tasks in patients with SZ. To this end, we conducted a signed differential mapping (SDM) meta-analysis of functional magnetic resonance imaging (fMRI) studies assessing abnormal responses elicited by tasks based on the oddball paradigm in patients with SZ. We conducted a similar SDM meta-analysis of neuroimaging studies of timing tasks in SZ. Finally, we undertook a multimodal meta-analysis to detect the common findings of the two previous meta-analyses. We found that SZ patients showed hypoactivation in cortical and subcortical areas related to timing. The dysfunction observed during timing tasks partially coincided with deficiencies in change-detection functions (particularly in the case of preattentional processing in the mismatch negativity response). We hypothesize that a dysfunctional timing/change detection network underlies the cognitive impairment observed in SZ.
