Gender differences and risk of readmission in hospitalizations with a diagnosis of psychotic spectrum disorders.

BACKGROUND: Gender differences in psychosis are a topic that has been studied considering different aspects. Although some available evidence would point to a possible better prognosis in women, this claim is far from conclusively established. METHODS: We propose an analysis of gender differences in the risk of readmission to an acute hospitalization unit, an indicator related to prognosis. RESULTS AND CONCLUSIONS: We found that although the risk of readmission at 1 year is lower in women, this seems to be explained by other confounding factors.

Is it possible to diagnose therapeutic adherence in mild cognitive impairment and dementia patients in clinical practice?

Background: Non-adherence is common and contributes to adverse health outcomes, reduced quality of life, and increased healthcare expenditure. The objective of this study was to assess the diagnostic validity to estimate the prevalence of non-adherence in patients with mild cognitive impairment (MCI) and dementia using two self-reported methods (SRMs) that are useful and easy in clinical practice, considering the pill count as a reference method (RM). Methods: The cohort study was nested in a multicenter randomized controlled trial NCT03325699. A total of 387 patients from 8 health centers were selected using a non-probabilistic consecutive sampling method. Inclusion criteria were as follows: a score of 20-28 points on the Mini-Mental State Examination (MMSE); older than 55 years; taking prescribed medication; and are in charge of their own medication use. Participants were followed up for 18 months after the baseline visit, i.e., 6, 12, and 18 months. Variables related with treatment adherences were measured in all visits. The variables included age, sex, treatment, comorbidities, and the MMSE test. Adherences included pill counts and Morisky-Green test (MGT) and Batalla test (BT) as SRMs. Statistical analysis included descriptive analysis and 95% confidence intervals (CIs). The diagnostic validity included the following: 1) open comparison statistical association between SRMs and RMs and 2) hierarchy comparison: the RM as the best method to assess non-adherence, kappa value (k), sensitivity (S), specificity (Sp), and likelihood ratio (PPV/PPN). Results: A total of 387 patients were recruited with an average age of 73.29 years (95% CI, 72.54-74.04), of which 59.5% were female. Comorbidities were 54.4% HTA, 35.9% osteoarticular pathology, and 24.5% DM. The MMSE mean score was 25.57 (95% CI, 25.34-25.8). The treatment adherence for the RM oscillates between 22.5% in the baseline and 26.3%, 14.8%, and 17.9% in the follow-up visits. For SRMs, the treatment adherence oscillates between 43.5% in the baseline and 32.4%, 21.9%, and 20.3% in the follow-up visits. The kappa value was statistically significant in all the comparison in all visits with a score between 0.16 and 035. Regarding the diagnostic validity, for the MGT, the sensibility oscillated between 0.4 and 0.58, and the specificity oscillated between 0.68 and 0.87; for the BT, the sensibility oscillated between 0.4 and 0.7, and the specificity oscillated between 0.66 and 0.9; and when both tests were used together, the sensibility oscillated between 0.22 and 0.4, and the specificity oscillated between 0.85 and 0.96. Conclusion: SRMs classify non-adherent subjects correctly. They are very easy to use and yield quick results in clinical practice, so SRMs would be used for the non-adherence diagnosis in patients with MCI and mild dementia.

Pharmacotherapeutic value of inflammatory and neurotrophic biomarkers in bipolar disorder: A systematic review.

BACKGROUND: The various pharmacological interventions, ranging from mood stabilizers and antipsychotics to antidepressants, reflect the diff/iculty of treating depressive/manic symptomatology of bipolar disorder (BD). Among a broad range of mechanisms implicated, immune dysregulation may contribute to the increased inflammation that influences the course of BD. Inflammatory, neurotrophic and oxidative stress factors may be identified as promising peripheral biomarkers in brain functioning, perhaps serving as predictors of an effective response to treatment for BD. The present systematic review aimed to examine the evidence supporting the pharmacotherapeutic value of inflammatory and neurotrophic biomarkers in BD. METHODS: PubMed, PsychINFO, Scopus and Web of Science were searched from inception to May 2024 by two independent reviewers. A total of 40 studies with 3371 patients with diagnosis and intervention of BD were selected. RESULTS: Inconsistencies in the effects of pharmacological treatments on the connection between the expected anti-inflammatory response and symptomatologic improvement were identified. Mood stabilizers (lithium), antipsychotics (quetiapine), antidepressants (ketamine) or their combination were described to increase both pro-inflammatory (TNFα, IL-6) and anti-inflammatory (IL-4, IL-8) factors. Other medications, such as memantine and dextromethorphan, autoimmune (infliximab) non-steroidal anti-inflammatory (aspirin, celecoxib) drugs, antidiabetics (pioglitazone), and even dietary supplementation (omega-3), or their combination, clearly decrease inflammatory factors (TNFα, IL-6, IL-1ß, C-reactive protein) and/or increase the neurotrophic factor BDNF in BD patients. CONCLUSION: Inflammation in BD requires further investigation to understand the underlying immunologic mechanism, to identify predictors of treatment response, and to make informed decisions about the use and development of more effective pharmacological interventions for BD.

Fine-mapping genomic loci refines bipolar disorder risk genes.

Bipolar disorder (BD) is a heritable mental illness with complex etiology. While the largest published genome-wide association study identified 64 BD risk loci, the causal SNPs and genes within these loci remain unknown. We applied a suite of statistical and functional fine-mapping methods to these loci, and prioritized 22 likely causal SNPs for BD. We mapped these SNPs to genes, and investigated their likely functional consequences by integrating variant annotations, brain cell-type epigenomic annotations, brain quantitative trait loci, and results from rare variant exome sequencing in BD. Convergent lines of evidence supported the roles of SCN2A, TRANK1, DCLK3, INSYN2B, SYNE1, THSD7A, CACNA1B, TUBBP5, PLCB3, PRDX5, KCNK4, AP001453.3, TRPT1, FKBP2, DNAJC4, RASGRP1, FURIN, FES, YWHAE, DPH1, GSDMB, MED24, THRA, EEF1A2, and KCNQ2 in BD. These represent promising candidates for functional experiments to understand biological mechanisms and therapeutic potential. Additionally, we demonstrated that fine-mapping effect sizes can improve performance and transferability of BD polygenic risk scores across ancestrally diverse populations, and present a high-throughput fine-mapping pipeline (https://github.com/mkoromina/SAFFARI).

Impulsivity, decision-making, and risk behavior in bipolar disorder and major depression from bipolar multiplex families.

OBJECTIVES: Bipolar disorder (BD) and major depressive disorder (MDD) are characterized by specific alterations of mood. In both disorders, alterations in cognitive domains such as impulsivity, decision-making, and risk-taking have been reported. Identification of similarities and differences of these domains in BD and MDD could give further insight into their etiology. The present study assessed impulsivity, decision-making, and risk-taking behavior in BD and MDD patients from bipolar multiplex families. METHODS: Eighty-two participants (BD type I, n = 25; MDD, n = 26; healthy relatives (HR), n = 17; and healthy controls (HC), n = 14) underwent diagnostic interviews and selected tests of a cognitive battery assessing neurocognitive performance across multiple subdomains including impulsivity (response inhibition and delay aversion), decision-making, and risk behavior. Generalized estimating equations (GEEs) were used to analyze whether the groups differed in the respective cognitive domains. RESULTS: Participants with BD and MDD showed higher impulsivity levels compared to HC; this difference was more pronounced in BD participants. BD participants also showed lower inhibitory control than MDD participants. Overall, suboptimal decision-making was associated with both mood disorders (BD and MDD). In risk-taking behavior, no significant impairment was found in any group. LIMITATIONS: As sample size was limited, it is possible that differences between BD and MDD may have escaped detection due to lack of statistical power. CONCLUSIONS: Our findings show that alterations of cognitive domains-while present in both disorders-are differently associated with BD and MDD. This underscores the importance of assessing such domains in addition to mere diagnosis of mood disorders.

Relación entre estrés y malestar psicológico de los padres y problemas emocionales y conductuales en niños preescolares con trastorno del espectro autista / Relationship between parental stress and psychological distress and emotional and behavioural problems in pre-school children with autistic spectrum disorder

INTRODUCCIÓN: Los trastornos del espectro autista (TEA) se caracterizan por deficiencias generalizadas en la comunicación social, estereotipias e intereses restringidos. Los TEA presentan una alta prevalencia de trastornos psiquiátricos adicionales que empeoran su funcionamiento diario y reducen la calidad de vida de ellos y sus familias. MATERIAL Y MÉTODO: En el esfuerzo de identificar características ambientales que expliquen esta alta comorbilidad, esta investigación se ha centrado en la sintomatología de estrés y malestar psicológico de los padres como posibles factores de riesgo. Se realizó un estudio transversal de asociación entre estrés y malestar psicológico de padres de niños preescolares con TEA (2-6 años) y su relación con psicopatología coexistente en niños con TEA. RESULTADOS Y CONCLUSIONES: Altos niveles de estrés y malestar psicológico en los padres están asociados ya desde la primera infancia con psicopatología coexistente en dicha población, específicamente con problemas emocionales y conductuales (p < 0,05). Sin embargo, se necesitan futuros estudios longitudinales para entender mejor la relación causal entre estas variables y su posible relación bidireccional

INTRODUCTION: The Autistic Spectrum Disorders (ASD) are characterised by general deficits in social communication, stereotypes, and restricted interests. The ASD have a high prevalence of additional psychiatric disorders that make their daily functioning worse, and reduces the quality of life of them and their families. MATERIAL AND METHODS: In an effort to identify family environmental characteristics that may influence in the course of additional psychiatric disorders, this study has focused on the symptoms of parental stress and psychological distress as possible risk factors. A cross-section study was carried out on the relationship between the stress and psychological distress of the parents and its relationship with co-existing psychopathology in a population of pre-school children with ASD (2-6 years). RESULTS AND CONCLUSIONS: High levels of stress and psychological distress of the parents arealready associated, since early childhood, with co-existing psychiatric symptoms, specifically with emotional and behavioural problems (p < 0.05). However, further longitudinal studies are needed for a better understanding of the causal relationship between these variables and their possible bidirectional relationship

El estudio Andalusian Bipolar Family (ABiF): protocolo y descripción de la muestra / The Andalusian Bipolar Family (ABiF) Study: Protocol and sample description

Introducción: Se presenta la primera descripción del estudio denominado Andalusian Bipolar Family (ABiF). Se trata de una investigación longitudinal con familias procedentes de Andalucía (España), que comenzó en 1997, con el objetivo de dilucidar las causas geneticomoleculares del trastorno afectivo bipolar. Desde entonces, esta cohorte ha contribuido a una serie de hallazgos clave, que han sido publicados en revistas internacionales. Sin embargo, el conocimiento sobre las bases genéticas del trastorno en estas familias sigue siendo limitado. Método: El estudio consta de dos fases: en la fase inicial se reclutaron 100 familias con múltiples afectados de trastorno bipolar y otros trastornos del ánimo. La segunda fase del proyecto, actualmente en curso, comenzó en 2013 con el objetivo de realizar un seguimiento de la cohorte de familias reclutadas originalmente. Los objetivos del estudio de seguimiento son: I) recoger nuevos datos clínicos longitudinales; II) realizar una evaluación neuropsicológica detallada, y III) obtener una extensa colección de biomateriales para futuros estudios moleculares. Resultados: El estudio ABiF, por tanto, generará unos recursos valiosos para futuras investigaciones sobre la etiología del trastorno afectivo bipolar; particularmente con respecto a las causas de la alta carga genética del trastorno en las familias con múltiples afectados. Discusión: Se discute el valor de este enfoque en relación con las nuevas tecnologías para la identificación de factores genéticos de alta penetrancia. Estas nuevas tecnologías incluyen la secuenciación del exoma y del genoma completo, y el uso de células madre pluripotentes inducidas u organismos modelo para la determinación de consecuencias funcionales

Introduction: Here, we present the first description of the Andalusian Bipolar Family (ABiF) Study. This longitudinal investigation of families from Andalusia, Spain commenced in 1997 with the aim of elucidating the molecular genetic causes of bipolar affective disorder. The cohort has since contributed to a number of key genetic findings, as reported in international journals. However, insight into the genetic underpinnings of the disorder in these families remains limited. Method: In the initial 1997-2003 study phase, 100 multiplex bipolar disorder and other mood disorder families were recruited. The ongoing second phase of the project commenced in 2013, and involves follow-up of a subgroup of the originally recruited families. The aim of the follow-up investigation is to generate: I) longitudinal clinical data; II) results from detailed neuropsychological assessments; and III) a more extensive collection of biomaterials for future molecular biological studies. Results: The ABiF Study will thus generate a valuable resource for future investigations into the aetiology of bipolar affective disorder; in particular the causes of high disease loading within multiply affected families. Discussion: We discuss the value of this approach in terms of new technologies for the identification of high-penetrance genetic factors. These new technologies include exome and whole genome sequencing, and the use of induced pluripotent stem cells or model organisms to determine functional consequences

Factores asociados a las demandas psiquiátricas a los servicios de urgencias prehospitalarios de Málaga (España) / Factors related to psychiatric calls to the Prehospital Emergency Care Services in Málaga (Spain)

Resumen: Introducción: En los últimos años se ha producido un importante aumento de la demanda asistencial de urgencias a nivel prehospitalario. Objetivo: El presente estudio tiene como objetivo principal identificar las variables asociadas a las demandas clasificadas como psiquiátricas a los Servicios de Urgencia y Emergencias Médicos Prehospitalarios (SUEMP) de la provincia de Málaga. Método: Estudio observacional retrospectivo de las demandas registradas en la base de datos informatizada (computarizada) del Centro Coordinador de Urgencias y Emergencias durante un año (N = 163 331). Se han considerado: 1) variables sociodemográficas: la edad y el sexo, y 2) variables relacionadas con la demanda: la franja horaria, el tipo de día, el trimestre del año, el sujeto alertante, el número de recursos movilizados, el número de personas atendidas y si hubo trasporte sanitario. Para la comparación de las variables se empleó la prueba χ2. También se realizó un análisis de regresión logística multivariante. Resultados: El 7% de las demandas a los SUEMP se clasificaron como psiquiátricas. Entre las variables relacionadas con las demandas psiquiátricas se encontraron tener menor edad, ser mujer, demanda realizada por la noche y la tarde, menor número de personas atendidas, que la alerta no fuera efectuada por el propio usuario y la no realización de traslado sanitario. Discusión y conclusión: Las demandas por problemas de salud mental presentan características diferenciales al resto de demandas a los SUEMP, lo que hay que tener en cuenta para mejorar la atención a dichos pacientes.

Abstract: Introduction: In recent years, there has been a significant increase in the demand for prehospital emergency care in different countries. Objective: The aim of the present study was to identify the variables associated with psychiatric calls to the Prehospital Emergency Care Services (PECS) in the province of Malaga. Method: An observational retrospective study based on calls made to the PECS and registered in the computerized database of the Coordination Emergency Centre during one year (N = 163 331). Independent variables included 1. sociodemographic variables: sex and age; and 2. variables related with the characteristics of each call: time of day, type of day, time of year, caller identification, number of resources needed, number of patients attended and type of solution. The χ2 test was used to compare of the variables. A multivariant logistic regression analysis was also carried out. Results: Psychiatric calls accounted for 7% of the total calls and were associated with: younger age, female gender, calls made in the evenings and afternoons, a lower number of patients attended, the call being performed by other individual calling on the patient's behalf, and no ambulance transportation. Discussion and conclusion: The calls concerned with mental health problems have specific characteristics which need to be taken into account in order to provide a better care for psychiatric patients.

Tendencias en las hospitalizaciones psiquiátricas de personas mayores de 65 años / Trends in psychiatric admissions in adults over 65 years old

INTRODUCCIÓN: El objetivo del estudio fue analizar la tendencia en el porcentaje de hospitalizaciones psiquiátricas en población mayor, así como, estudiar las características de la población mayor ingresada en una unidad de hospitalización psiquiátrica. MATERIAL Y MÉTODOS: Se analizaron las tendencias en los porcentajes de altas de población mayor a nivel nacional y de los porcentajes de ingresos de la Unidad de Hospitalización de Salud Mental (UHSM) del Hospital Regional Universitario de Málaga durante un periodo de al menos 18años mediante regresión segmentada. Para el estudio de las características de la población mayor ingresada se compararon todos los pacientes (n=5.925) y los episodios de ingreso (n=15.418) consecutivos entre los años 1999 y 2017 en la UHSM. RESULTADOS: A nivel nacional hubo un incremento de las altas hospitalarias por trastorno mental en personas mayores con un significativo cambio de porcentaje anual medio del 2,0%. En la unidad de estudio esta población fue en mayor medida de género femenino, admitida de forma involuntaria y tuvo un tiempo de estancia mayor. Presentaron con más frecuencia trastornos mentales de tipo orgánico y trastorno depresivo y con menor frecuencia esquizofrenia, trastornos por consumo de sustancias y trastornos de personalidad. CONCLUSIONES: Hubo una tendencia creciente en el porcentaje de personas mayores con hospitalizaciones psiquiátricas en el periodo de estudio. Estos resultados alertan sobre el aumento de admisiones de esta población en las unidades de hospitalización de psiquiatría y la necesidad de adaptación de estas unidades a las características particulares de estos pacientes

BACKGROUND: The aim of this study was to analyse the trend in the percentages of elderly patients admitted to hospital for psychiatric reasons. An additional aim was to analyse the characteristics of the elderly population admitted to a psychiatric hospitalisation unit. Material an METHODS: An analysis was made of the trends in the percentages of discharges in elderly population at the national level and in the Mental Health Hospitalisation Unit (MHHU) of the Regional University Hospital of Malaga for a period of at least 18years using segmented regression. For the study of the characteristics of the elderly population, all patients (N=5,925) and consecutive episodes of admission (N=15,418) were compared between 1999 and 2017 in the MHHU. RESULTS: At the national level, there was an increase in hospital discharges in elderly patients with a significant mean annual percent change of 2.0%. In the study unit, the elderly population were more frequently female, involuntarily admitted, and had a longer hospital stay. They had been diagnosed more frequently with organic and depressive mental disorders, and less frequently with schizophrenia, substance use, and personality disorders. CONCLUSIONS: There was a growing trend in the percentage of elderly psychiatric patients admitted to hospitals during the study period. These results point to the increase in elderly psychiatric admissions and thus the need to adapt psychiatric units to the characteristics of this population
