Efficacy of Smartphone Apps in Patients With Depressive Disorders: A Systematic Review.

Background: Digital interventions have become an accessible format in clinical practice to provide better support for patients with mental disorders. However, the clinical efficacy in patients with depressive disorders is not well known. We aimed to determine the efficacy of smartphone applications (apps) in patients diagnosed with a depressive disorder. Method: An electronic database search was performed of PubMed, PsycINFO, and Web of Science, to identify relevant articles up to June 12, 2021. Peer-reviewed articles were screened and selected based on predetermined inclusion and exclusion criteria. Results: Seven articles met the inclusion criteria and therefore were selected for the systematic review, which included a total of 651 patients. The results were heterogeneous, essentially due to the different methodologies used in the selected studies. Conclusions: Digital smartphone-delivered interventions do not appear to reduce depressive symptomatology nor improve the quality of life in patients diagnosed with depressive disorders when compared to an active control group. Taking into account the inherent methodological difficulties and the variability among such studies, it is apparent that further research-with more methodologically refined clinical trials, including larger sample sizes-is needed.

The relationship between human development and prevalence of deficit schizophrenia: Results from a systematic review and meta-analysis.

This study examined the relationship between the prevalence of deficit schizophrenia (DS) and a country's Human Development Index (HDI). A systematic review and meta-analysis of the literature published in the last decade were conducted to acquire data on the worldwide prevalence of deficit syndrome in schizophrenia cohorts and examine the correlation between DS prevalence and the HDI of the countries in the review. Twenty-six studies meeting our eligibility criteria provided prevalence data on DS in 14 countries with both low-to-middle and high-incomes, ranging from 14.34%-to 61.57%. The pooled prevalence of DS was 32.19% (95% CI = 26.17 to 38.52). Statistical analysis yielded a correlation coefficient (r) of -0.518 (95% CI = -0.754 to -0.164; p = 0.007), indicating a moderate inverse correlation between DS prevalence and HDI. This relationship remained significant in partial correlation analysis after controlling for potential sources of bias in the DS estimates (r = -0.489, p = 0.013). Our results show that schizophrenia cohorts from low-to-middle-income countries are more prone to primary and enduring negative symptoms, and contribute to the emerging evidence questioning the axiom that schizophrenia in the developing world has a better course than in high-income countries.

Clinical characterization of brief psychotic disorders triggered by the COVID-19 pandemic: a multicenter observational study.

This study aimed to characterize the clinical profile of patients with brief psychotic disorders (BPD) triggered by the psychosocial distress derived from the COVID-19 crisis. A multicenter study was conducted from March 14 to May 14, 2020 (the peak weeks of the pandemic in Europe). All consecutive patients presenting non-affective psychotic episodes with a duration of untreated psychosis of less than 1 month and whose onset was related to the COVID-19 crisis were recruited, but only those patients meeting Diagnostic Statistical Manual 5th edition (DSM-5) criteria for "BPD with marked stressors" (DSM-5 code: 298.8) during follow-up were finally included. Patients' sociodemographic and clinical characteristics were collected at baseline and summarized with descriptive statistics. During the study period, 57 individuals with short-lived psychotic episodes related to the emotional stress of the COVID-19 pandemic were identified, of whom 33 met DSM-5 criteria for "BPD with marked stressors". The mean age was 42.33 ± 14.04 years, the gender distribution was almost the same, and the majority were rated as having good premorbid adjustment. About a quarter of the patients exhibited suicidal symptoms and almost half presented first-rank schizophrenia symptoms. None of them were COVID-19 positive, but in more than half of the cases, the topic of their psychotic features was COVID-19-related. The coronavirus pandemic is triggering a significant number of BPD cases. Their risk of suicidal behavior, their high relapse rate, and their low temporal stability make it necessary to closely monitor these patients over time.

Preventing Post Traumatic Stress Disorder in the general population induced by trauma during the COVID pandemic: A simple brief intervention based on cognitive science that could be delivered digitally.

Most of the recent studies indicated the prevalence of Post-Traumatic Stress Symptoms (PTSS) are increasing after the COVID pandemic around the world. Bo et al. reported PTSS prevalence of 96.2% among the COVID-19-infected people. The sociocultural and individual vulnerability and protective factors may influence onset and maintenance of the symptoms. However, there is significant lack in understanding the risk factors and preventive factors that influence the maintenance of Post-Traumatic Stress symptoms that defines Post-Traumatic Stress Disorder (PTSD). The digital technology gives us the unique opportunity to assess this risk, to monitor and track this evolution longitudinally. In this research project we aimed to design and develop a smartphone application for longitudinal data collection enabling to (1) predict and follow the evolution of PTSS toward PTSD, (2) assess the relative efficacy of several methods to prevent the evolution of PTSS right after exposure to trauma (1-24 h), (3) educate people about psychological effects that can occur during and after trauma, normalize acute distress and refer to professional help if a disorder is constituted. We hope that this research project will help to understand how to maximize the self help support during the acute phase (golden hours) after trauma to prevent the transition from PTSS to PTSD.

Non-alcoholic fatty liver disease (NAFLD) as a neglected metabolic companion of psychiatric disorders: common pathways and future approaches.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis in over 5% of the parenchyma in the absence of excessive alcohol consumption. It is more prevalent in patients with diverse mental disorders, being part of the comorbidity driving loss of life expectancy and quality of life, yet remains a neglected entity. NAFLD can progress to non-alcoholic steatohepatitis (NASH) and increases the risk for cirrhosis and hepatic carcinoma. Both NAFLD and mental disorders share pathophysiological pathways, and also present a complex, bidirectional relationship with the metabolic syndrome (MetS) and related cardiometabolic diseases. MAIN TEXT: This review compares the demographic data on NAFLD and NASH among the global population and the psychiatric population, finding differences that suggest a higher incidence of this disease among the latter. It also analyzes the link between NAFLD and psychiatric disorders, looking into common pathophysiological pathways, such as metabolic, genetic, and lifestyle factors. Finally, possible treatments, tailored approaches, and future research directions are suggested. CONCLUSION: NAFLD is part of a complex system of mental and non-communicable somatic disorders with a common pathogenesis, based on shared lifestyle and environmental risks, mediated by dysregulation of inflammation, oxidative stress pathways, and mitochondrial function. The recognition of the prevalent comorbidity between NAFLD and mental disorders is required to inform clinical practice and develop novel interventions to prevent and treat these complex and interacting disorders.

Reactive psychoses in the context of the COVID-19 pandemic: clinical perspectives from a case series / Psicosis reactivas en el contexto de la pandemia del COVID-19: perspectivas clínicas de una serie de casos

INTRODUCTION: The world is currently undergoing an extremely stressful scenario due to the COVID-19 pandemic. This unexpected and dramatic situation could increase the incidence of mental health problems, among them, psychotic disorders. The aim of this paper was to describe a case series of brief reactive psychosis due to the psychological distress from the current coronavirus pandemic. MATERIALS AND METHODS: We report on a case series including all the patients with reactive psychoses in the context of the COVID-19 crisis who were admitted to the Virgen del Rocío and Virgen Macarena University Hospitals (Seville, Spain) during the first two weeks of compulsory nationwide quarantine. RESULTS: In that short period, four patients met the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for a brief reactive psychotic disorder. All of the episodes were directly triggered by stress derived from the COVID-19 pandemic and half of the patients presented severe suicidal behavior at admission. CONCLUSIONS: We may now be witnessing an increasing number of brief reactive psychotic disorders as a result of the COVID-19 pandemic. This type of psychosis has a high risk of suicidal behavior and, although short-lived, has a high rate of psychotic recurrence and low diagnostic stability over time. Therefore, we advocate close monitoring in both the acute phase and long-term follow-up of these patients

INTRODUCCIÓN: El mundo está experimentando un escenario extremadamente estresante a causa de la pandemia del COVID-19. Esta situación inesperada y dramática podría incrementar la incidencia de los problemas de salud mental y, entre estos, los trastornos psicóticos. El objetivo de este documento es describir una serie de casos de psicosis reactiva breve, debidos al distrés psicológico debido a la pandemia actual de coronavirus. MATERIALES Y MÉTODOS: Reportamos una serie de casos que incluye a todos los pacientes con psicosis reactiva en el contexto de la crisis del COVID-19, ingresados en los Hospitales Universitarios Virgen del Rocío y Virgen Macarena (Sevilla, España) durante las 2 primeras semanas de la cuarentena obligatoria a nivel nacional. RESULTADOS: En este breve espacio de tiempo, 4 pacientes cumplieron los criterios de trastorno psicótico breve del manual diagnóstico y estadístico de trastornos mentales (DSM-5). Todos los episodios fueron desencadenados por el estrés derivado de la pandemia del COVID-19, y la mitad de los pacientes presentaron un comportamiento suicida grave a su ingreso. CONCLUSIONES: Actualmente podemos estar asistiendo a un incremento del número de trastornos psicóticos reactivos breves, como resultado de la pandemia del COVID-19. Este tipo de psicosis tiene un elevado riesgo de comportamiento suicida y, aunque es transitorio, tiene una elevada tasa de recurrencia psicótica y baja estabilidad diagnóstica a lo largo del tiempo. Por tanto, somos partidarios de una supervisión estrecha tanto en la fase aguda como en el seguimiento a largo plazo de estos pacientes

Characterization of deficit schizophrenia and reliability of the bidimensional model of its negative symptomatology.

Background: Cumulative evidence has demonstrated important differences between deficit (DS) and non-deficit (NDS) schizophrenia, suggesting that DS may be a separate disease. However, most data come from the same research groups and more replication is needed to validate this hypothesis.Aims: Our study aimed to examine the distribution of DS, to compare their characteristics with NDS patients and to analyze the reliability of the two-factor structure of its negative symptomatology in a Spanish clinical sample.Methods: Sixty clinically stabilized patients with schizophrenia were evaluated. The Schedule for the Deficit Syndrome was used for DS/NDS categorization. Patient characteristics included age, gender, education, age at onset of psychosis, duration of illness, family history of psychosis, type of antipsychotic regimen, schizophrenia subtype and severity of the disease.Results: DS prevalence was 28.3%. Bivariate analysis revealed statistical differences between DS and NDS in terms of years of education and schizophrenia subtype. Factor analysis replicated the two-factor solution consisting of the 'Expressive deficit' and 'Avolition-apathy' domains reported in previous studies.Conclusions: Our results were consistent with the published data and indicated that the DS profile in the Spanish population is similar to that in other populations, which would corroborate the homogeneity of DS within the schizophrenia spectrum and contribute to the hypothesis that DS constitutes a separate disease.
