Clinical predictors of suicidal ideation, suicide attempts and suicide death in depressive disorder: a systematic review and meta-analysis.

Patients with depressive disorders are especially prone to suicide risk. Among the clinical predictors of suicidality, those specifically related to depressive disorders have not been accurately detailed. Our aim was to conduct a systematic review and meta-analysis of studies reporting longitudinal predictors of suicidal ideation, suicide attempts and suicide death within depression, including diagnostic subtypes, symptoms, clinical course, and assessment scales. A systematic search of the literature between 2001 and 2022 identified 4422 references, among which 19 studies providing 45 different predictors of suicidality met the inclusion criteria. Random effects meta-analyses were performed for 22 predictors, three for suicidal ideation, eleven for suicide attempts and eight for suicide death. Heterogeneity and publication bias were inspected through I2 tests and Egger's tests respectively. Meta-analysis results showed that severity of hopelessness predicted suicidal ideation and suicide attempts. History of suicide attempts, suicidal ideation, severe depression, and psychotic symptoms predicted subsequent suicide attempts and suicide death. Time to full remission and sleep disturbances were also found as relevant predictors of future suicide behaviours. This review specifies which predictors of suicidality within the clinical features of depression will help clinicians and policy makers to better prevent suicide risk in patients with depressive disorders. Further longitudinal studies are needed to reliably assess the predictive ability of our results and to analyse other possible clinical predictors to prevent suicidality, especially with regard to suicidal ideation.

Mindfulness skills and experiential avoidance as therapeutic mechanisms for treatment-resistant depression through mindfulness-based cognitive therapy and lifestyle modification.

Background/objective: The COVID-19 pandemic and consequent physical distancing has made it difficult to provide care for those with Treatment-Resistant Depression (TRD). As a secondary analysis of a clinical trial, the aim of this study was to explore potential mechanisms through which three online-delivered approaches, added to treatment as usual, improve depressive symptoms in TRD patients. Methods: The three approaches included (a) Minimal Lifestyle Intervention (MLI), (b) Mindfulness-Based Cognitive Therapy (MBCT), and (c) Lifestyle Modification Program (LMP). Sixty-six participants with TRD completed assessments pre-post intervention (mindfulness skills [FFMQ]; self-compassion [SCS]; and experiential avoidance [AAQ-II]) and pre-intervention to follow-up (depressive symptoms [BDI-II]). Data were analyzed using within-subjects regression models to test mediation. Results: Mindfulness skills mediated the effect of MBCT on depressive symptoms (ab = -4.69, 95% CI = -12.93 to-0.32), whereas the lack of experiential avoidance mediated the effect of LMP on depressive symptoms (ab = -3.22, 95% CI = -7.03 to-0.14). Conclusion: Strengthening mindfulness skills and decreasing experiential avoidance may promote recovery in patients with TRD, MBCT, and LMP have demonstrated that they may help increase mindfulness skills and decrease experiential avoidance, respectively. Future work will need to unpick the components of these interventions to help isolate active ingredients and increase optimization.

Efficacy of an adjuvant non-face-to-face multimodal lifestyle modification program for patients with treatment-resistant major depression: A randomized controlled trial.

BACKGROUND: The high prevalence of depression is partly attributable to the poor response of patients to first-line antidepressants. Multimodal programs that promote a healthy lifestyle are successful in treating depression when used as a complementary therapy, but their medium- and long-term benefits have not been demonstrated for patients with treatment-resistant depression (TRD). The main aim of this study was to compare the effectiveness of a lifestyle modification program (LMP) with mindfulness-based cognitive therapy (MBCT) and a placebo-control (written suggestions for lifestyle changes) in Spanish patients with TRD. METHODS: This controlled clinical trial randomized 94 patients with TRD into 3 arms. The primary outcome was the Beck Depression Inventory-II (BDI-II) score at baseline, 2, 6 and 12 months. The secondary outcomes were changes in scores that evaluated quality-of-life, adherence to the Mediterranean diet, physical activity, and social support. RESULTS: Relative to the placebo group, the LMP and MBCT groups had significantly better quality of life (p = 0.017; p = 0.027), and the LMP group had significantly better adherence to the Mediterranean diet (p<0.001) and reduced use of antidepressants (p = 0.036). However, the three groups showed no significant differences in BDI-II score. LIMITATIONS: Only about half of the planned 180 patients were recruited, in part due to the COVID-19 pandemic. CONCLUSIONS: There was no evidence that the LMP treatment significantly reduced symptoms of depression relative to the other groups during the COVID-19 lockdown.

Development and Evaluation of a Digital Health Intervention to Prevent Type 2 Diabetes in Primary Care: The PREDIABETEXT Study Protocol for a Randomised Clinical Trial.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a highly prevalent disease associated with an increased risk of comorbidities, premature death, and health costs. Prediabetes is a stage of glucose alteration previous to T2DM, that can be reversed. The aim of the study is to develop and evaluate a low-intensity, multifaceted, digital intervention to prevent T2DM. The intervention comprises: (1) the use of mobile health technology to send tailored text messages promoting lifestyle changes to people at risk of T2DM and (2) the provision of online education to primary healthcare physicians and nurses about management of prediabetes. METHODS: In stages 1-4 we will design, develop and pilot-test the intervention. In Stage 5 we will conduct a phase II, six-month, three-arm, cluster randomized, clinical trial with 42 primary care professionals and 420 patients at risk of T2DM. Patients will be allocated to a control group (usual care), intervention A (patient messaging intervention), or intervention B (patient messaging intervention plus online education to their primary healthcare professionals). The primary outcome will be glycated haemoglobin. All the procedures obtained ethical approval in June 2021 (CEI-IB Ref No: IB4495/21PI). DISCUSSION: Digital health interventions can effectively prevent T2DM and reduce important T2DM risk factors such as overweight or hypertension. In Spain, this type of intervention is understudied. Moreover, there is controversy regarding the type of digital health interventions that are more effective. Findings from this study may contribute to address T2DM prevention, through a low-cost and easily implementable intervention.

Consumo moderado de alcohol y prevención de la depresión. Una revisión crítica / Moderate alcohol consumption and depression prevention. A critical review

Introducción. Hay un claro consenso en torno a que los trastornos por uso de alcohol se asocian con una mayor incidencia y peor pronóstico de depresión, además de otros problemas médicos. Sin embargo, se está planteando que el consumo de alcohol moderado previene y mejora la evolución de algunas enfermedades crónicas, especialmente cardiovasculares. No obstante, otros investigadores sugieren que no hay un consumo seguro de alcohol debido a sus efectos globales sobre la salud (aumento del riesgo de cáncer, por ejemplo). En relación a la depresión, también hay evidencia dispar sobre el posible efecto antidepresivo del consumo moderado de alcohol. Esta revisión crítica intenta resumir dicha evidencia, así como analizar la posible influencia relativa de factores involucrados. Metodología. Se realizó una búsqueda a través de PubMedncon las siguientes palabras claves y operadores booleanos: (“light alcohol” OR “light drinking” OR “moderate alcohol” OR “moderate drinking” OR “low risk drinking” OR “low risk alcohol”) AND (depress*) NOT (dependence OR abuse). Resultados. La mayoría de los 24 estudios seleccionados fueron longitudinales. El consumo moderado de alcohol se asocia a menor sintomatología depresiva en la mayoría de los estudios. Sin embargo, estos estudios no descartan que esta asociación pueda explicarse alternativamente por importantes factores de confusión no causales (estado de salud, comportamiento prosocial, otros factores de estilo de vida relacionados, etc.). Conclusiones. No hay evidencia científica clara y consistente actual que respalde el consumo moderado de alcohol per se como factor protector frente a la depresión.(AU)

Background. There is a clear consensus that alcohol use disorders are associated with poorer outcomes concerning depression, and that drinking alcohol shouldn`t be recommended because of the risk of dependence. Until recently, literature focused almost exclusively on patients with alcohol use disorders and excludes patients with moderate alcohol use (MAU). It’s has been shown that MAU can prevent or improve the evolution of chronic diseases such as cardiovascular diseases, but several researchers have suggested that there is no safe level of alcohol drinking due to other effects on health. Nevertheless, there is some evidence regarding the antidepressant effect of moderate alcohol consumption. This critical review aims to sum up the direction and tendency of current research on the effect of MAU on depression and relate the causal or confounders factors that might explain the results. Methods. A research was carried out through PubMed with the following keywords and Boolean operators: (“light alcohol” OR “light drinking” OR “moderate alcohol” OR “moderate drinking” OR “low risk drinking” OR “low risk alcohol”) AND (depress*) NOT (dependence OR abuse). Results. Most of the 23 studies selected aim to investigate longitudinal effects. MAU prevents depressive symptoms in most studies, but it is still unclear to what extent this can be alternatively explained by neurochemical factors or other confounding factors (health status, sociability, other related lifestyle factors, etc.). Conclusion. There is currently no clear and consistent scientific evidence to support moderate alcohol consumption per se as a protective factor against depression.(AU)

Effectiveness of a healthy lifestyle promotion program as adjunctive teletherapy for treatment-resistant major depression during COVID 19 pandemic: A randomized clinical trial protocol.

INTRODUCTION: Treatment-resistant depression (TRD) has a high prevalence and can be exacerbated by poor physical health and economic hardships, which have become common stressors during the current COVID-19 pandemic. The therapeutic approaches used to treat these patients are not always available, may be not be accepted by some patients, and often require face-to-face interactions. OBJECTIVE: The main aim of this study will be to evaluate the effectiveness of an Internet-based adjuvant lifestyle-based intervention for patients with TRD. METHODS: This will be a parallel, randomized, and controlled clinical trial. A total of 180 patients with TRD will be randomly allocated (1:1:1) to 1 of 3 groups: treatment prescribed by the mental health team and written suggestions for lifestyle changes (placebo control group); treatment prescribed by the mental health team, written suggestions for lifestyle changes, and an 8-week mindfulness-based cognitive therapy program (active control group); or treatment prescribed by the mental health team, written suggestions for lifestyle changes, and an 8-week lifestyle change promotion program (intervention group). We will perform this study during the COVID-19 pandemic, and will administer interventions by teletherapy, and contact participants by telephone calls, text messages, and/or teleconferences. We will collect patient data using questionnaires administered at baseline, immediately after the intervention, and after 6 and 12 months. The primary outcome will be score on the Beck Depression Inventory-II. The secondary outcomes will be score on the Clinical Global Impressions Scale (used to quantify and track patient progress and treatment response over time) and health-related quality of life measured using the European Quality of Life-5 Dimensions Questionnaire. DISCUSSION: Patients with TRD are especially vulnerable when face-to-face psychotherapy is unavailable. The main strength of the proposed study is the novelty of the intervention to be used as an adjuvant therapy. Our results may provide guidance for treatment of patients with TRD in future situations that require lockdown measures. CLINICALTRIALS REGISTRATION NUMBER: NCT04428099.

Estilo de vida saludable: un factor de protección minusvalorado frente a la depresión / Healthy lifestyle: an undervalued protection factor against depression

Los índices de depresión en el mundo desarrollado se han incrementado en las últimas décadas. Según el informe de la OMS, publicado en 2012, aproximadamente el 5% de la población refiere haber experimentado un episodio depresivo en algún momento de su vida. En los últimos años se están investigado qué factores pueden ser los responsables, como la merma de la calidad de la dieta, de las horas de sueño, de la actividad física, de la exposición a luz ambiental o del lazo social. Todos estos factores aumentan la vulnerabilidad para la depresión hasta el punto de que, lo mismo que le ocurre a la diabetes o las enfermedades cardiovasculares, la depresión se considera como una «enfermedad de la modernidad», aludiendo a que los cambios en nuestras rutinas pueden predisponer la aparición de las mismas. En coherencia con ello, ayudar a que el paciente mejore sus hábitos de vida podría tener un impacto positivo en su clínica depresiva, como efectivamente se está demostrando. Los tratamientos de los que disponemos en la actualidad, como los fármacos o la psicoterapia, no siempre demuestran ser totalmente eficaces, y hay estimaciones de que solo en torno al 50% de los pacientes tratados por depresión presentan remisión total sin precisar otro tipo de intervenciones. En este trabajo describimos un programa multimodal de estilo de vida para pacientes con depresión que aborda los factores mencionados y que se ha denominado programa de «estilo de vida mediterráneo». Concluimos planteando que el estilo de vida saludable, aunque está en retroceso en muchas partes del mundo, es un factor protector frente a la depresión y muchos pacientes pueden recuperarlo con ayuda específica (AU)

Depression rates have increased in recent decades in the developed world. According to the WHO report published in 2012, approximately 5% of the population refer to having experienced a depressive episode at some point in their life. In the last few years, the factors responsible for reducing the quality of diet, sleeping hours, physical activity, exposure to ambient lighting, or social environment are being investigated. All of these factors increase the vulnerability to depression to the point that, like diabetes or cardiovascular disease, depression is considered as a "modern disease", referring to the changes we make in our lifestyles that may predispose to the appearance of these diseases. Consequently, helping patients to improve their lifestyles could have a positive impact on their depressive symptoms, as is being demonstrated. Current available treatments, such as drugs or psychotherapy, do not always prove to be fully effective, and there are estimates that only about 50% of patients treated for depression have total remission without requiring other interventions. In this paper, we describe a multimodal lifestyle program for patients with depression that addresses the above factors and has been labelled as the "Mediterranean lifestyle" program. It is concluded that healthy lifestyle (a regressive lifestyle in many parts of the world), is a protective factor against depression, and many patients can recover from it with specific help (AU)

The Mediterranean diet and micronutrient levels in depressive patients / Dieta mediterránea y niveles de micronutrientes en pacientes depresivos

Introduction: An inverse association between depression and some serum micronutrient levels (selenium, zinc, iron, magnesium, vitamin B and folic acid) has been reported. In addition, other studies reported that this micronutrient supplementation may improve depressed mood. The Mediterranean diet contains a sufficient amount of the micronutrients mentioned, although no study has reported an association between diet prescription and increased levels of them in depressive patients. Objective: To examine the impact of dietary patterns recommendations on micronutrient levels in depressive patients. Methods: 77 outpatients were randomly assigned either to the active (hygienic-dietary recommendations on diet, exercise, sleep, and sun exposure) or control group. Outcome measures were assessed before and after the six month intervention period. Results: Serum selenium and zinc levels were slightly low at basal point and serum selenium was inversely correlated with severity of depression (r=-0.233; p=0.041). A better outcome of depressive symptoms was found in the active group. Nevertheless, no significant differences in micronutrient levels were observed after the Mediterranean diet pattern prescription, probably due to an insufficient adherence. Conclusion: Selenium, zinc, iron, magnesium, vitamin B12 and folic acid serum levels didn`t increase in depressed patients after six months of the Mediterranean diet pattern prescription (AU)

Introducción: Se ha comunicado una correlación inversa entre depresión y el nivel sérico de algunos micronutrientes (selenio, zinc, hierro, magnesio, vitamina B y ácido fólico). Además, otros estudios han señalado que la suplementar de estos micronutrientes puede mejorar la depresión. La dieta mediterránea proporciona una suficiente cantidad de los micronutrientes mencionados, aunque ningún estudio ha probado si la prescripción de dicha dieta puede incrementar los niveles de micronutrientes en pacientes depresivos. Objetivo: Examinar el impacto de recomendar un patrón dietético mediterráneo en los niveles de micronutrientes de pacientes deprimidos. Material y Métodos: 77 pacientes ambulatorios se aleatorizaron entre un grupo de intervención (recomendaciones higiénico-dietéticas sobre dieta, ejercicio, sueño y exposición solar) y un grupo control. La evolución fue evaluada antes y después de los seis meses del periodo de intervención. Resultados: Los niveles de selenio y de zinc fueron ligeramente bajos en la determinación basal y el nivel de selenio correlacionaba inversamente con la severidad de la depresión (r=-0.233; p=0.041). El grupo activo evolucionó mejor de la clínica depresiva. Sin embargo, no se observaron diferencias significativas en los niveles de micronutrientes después de la prescripción del patrón de dieta mediterránea probablemente a causa de una insuficiente adherencia. Conclusión: Los niveles séricos de selenio, zinc, hierro, magnesio vitamina B12 y ácido fólico no aumentaron en pacientes depresivos seis meses después de prescribir un patrón de dieta mediterránea (AU)

Prescripción de ejercicio físico en la depresión por parte de Médicos de Familia. Factores involucrados / Prescrição de exercício físico na depressao por parte de médicos de família. factores envolvidos / Exercise prescription for depression by general practitioners, factors involved

El problema del sedentarismo es acuciante en sociedades desarrolladas y sus consecuencias para la salud de la población constituyen uno de los principales problemas de salud pública actuales. La depresión es un motivo de consulta muy habitual en las consultas de atención primaria de países occidentales. Se ha planteado la prescripción de ejercicio físico como una estrategia antidepresiva útil en depresiones leves-moderadas, con frecuencia de forma complementaria a los tratamientos de primera elección. Sin embargo, los médicos de atención primaria no siempre lo prescriben y se desconoce de qué depende que lo hagan. Contribuir a aclarar esta cuestión es el objetivo del presente trabajo. Nuestra hipótesis era que el grado de prescripción depende de sus opiniones y experiencia sobre el tratamiento de la depresión.Se trata de un estudio descriptivo transversal en el que participaron 13 centros de salud. Utilizamos el cuestionario Depression Questionaire Attitude para valorar la actitud de los médicos hacia la depresión, y recogimos otras variables relacionadas con la importancia que otorgaban al ejercicio físico y a otros aspectos del estilo de vida en la salud física y mental. Los resultados confirman que la actitud de los médicos frente a la depresión influye en su disposición a recomendar ejercicio físico. Además, los médicos de atención primaria con menos años de práctica profesional valoran más el papel del ejercicio físico en la salud, tanto en la depresión como en otras patologías médicas. También se observa una correlación entre la importancia que se da al ejercicio físico en la salud y la que se da a otros factores ligados al estilo de vida, especialmente la dieta. Se concluye que aunque la utilidad de recomendar ejercicio físico en la depresión va acercándose al mismo nivel de importancia que en otros problemas de salud, su empleo por parte de los médicos de atención primaria es muy mejorable. Por ello, es importante insistir en la necesidad de ofrecer apoyo y programas de formación continuada a los médicos de atención primaria para ayudarles en este propósito (AU)

A sedentary lifestyle is an urgent problem in developed societies and its consequences are one of the main current problems in public health. Depression is a common reason to attend primary care in Western countries. In many cases of low and mild depression, exercise is recommended as a complement to the main therapy: Psychotherapy and/or pharmacotherapy. Nevertheless, general practitioners do not always recommend exercise to depressive patients and it is unknown why they do not. The main aim of our study was to clarify how the degree of prescribing exercise relies on a general practitioner’s opinion and experience in depression treatment. A cross-sectional design was undertaken in 13 public health centers. The Depression Attitude Questionnaire (DAQ) was used to evaluate general practitioners’ attitude towards depression; other variables related to the importance accorded to physical exercise; and other lifestyle aspects of physical and mental health. Our results show that general practitioners’ attitude towards depression influence their willingness to recommend exercise. Moreover, less experienced general practitioners (in years) tend to appreciate the importance of exercise in health, not only in depression. A positive relationship was found between importance of exercise and importance accorded to other factors linked to lifestyle, especially diet. Although recommendation of exercise in depression is similar to other medical conditions, its prescription may be improved. Hence, it is important to point out the need for education programs for general practitioners, in order to improve their capacity to deal with their task (AU)

Para tal, é importante insistir na necessidade de oferecer apoio e programasde formação continuada aos médicos de cuidados primários para ajudá-los neste propósito

Metabolic syndrome improvement in depression six months after prescribing simple hygienic-dietary recommendations.

BACKGROUND: Changes in diet and exercise have been separately demonstrated to improve Depression, although scientific evidence available is scarce. In a previously published controlled study, just recommending these and other lifestyle measures (sleep restriction and sunlight exposure) in combination once, patients experienced improvements in their depressive symptoms six months later. In this sample, one in three depressive patients had metabolic syndrome (MetS) at baseline. First line treatment of MetS condition is hygienic-dietetic, being Mediterranean diet and exercise especially important. Therefore we analyzed if lifestyle recommendations also improved their metabolic profile. FINDINGS: During the sixth month evaluation, a smaller number of patients from the group receiving hygienic-dietary recommendations met MetS criteria comparing with the control group. CONCLUSIONS: This study suggests that costless lifestyle recommendations, such as exercise and Mediterranean diet, have the capacity to promote both mental and physical health in a significant proportion of depressive patients. Further research is needed to confirm or discard these preliminary findings.
