Epidemiology of social phobia in Andalusia.

INTRODUCTION: Population studies on social anxiety disorder (SAD) are relatively scarce and there is no previous reported evidence on prevalence or correlates of SAD in an Andalusian general population sample. MATERIAL AND METHODS: We used a random representative sample previously identified via standard stratification procedures. Thus, a final sample of 4507 participants were included (response rate 83.7%). Interviewees were thoroughly assessed on sociodemographic, clinical and psychosocial factors, including: exposures to threatening life events (TLEs), childhood abuse, personality disorder and traits (neuroticism, impulsivity, paranoia), global functioning, physical health and toxics consumption. SAD diagnosis was ascertained using the Mini International Neuropsychiatric Interview. Both, pooled prevalences (with 95% confidence intervals) and risk correlates for SAD were estimated using binary logistic regression. RESULTS: Estimated prevalence for SAD was 1.1% (95% CI=0.8-1.4). Having a SAD diagnosis was independently and significantly associated with younger age, poorer global functioning, higher neuroticism and paranoia personality traits, having suffered childhood abuse and exposure to previous TLEs. Furthermore, SAD was significantly associated with comorbid personality disorder, major depression, panic disorder and alcohol abuse. CONCLUSIONS: Among this large Andalusian population sample, the prevalence of SAD and its associated factors are relatively similar to previously reported international studies, although no population study had previously reported such a strong association with paranoia.

An epidemiological survey on personality disorder in Andalusia (the PISMA-ep PD study).

BACKGROUND: Despite a significant clinical and social burden, there is a relative scarcity of epidemiological studies on Personality Disorder (PD). AIM: To determine the current prevalence of PD and the psychosocial correlates associated with this in the Andalusian population. METHOD: We carried out a cross-sectional population mental-health survey in Andalusia, southern Spain. Thus, 4,518 randomly selected participants were interviewed following sampling using different standard stratification levels. We used the Spanish version of the SAPAS to estimate PD prevalence. In addition, a full battery of other instruments was utilized to explore global functionality, childhood abuse, maltreatment, threatening life events, personality traits (neuroticism, impulsivity and paranoia), medical and psychiatric comorbidities, family history of psychological problems and other potential risk factors for PD. RESULTS: PD prevalence (10.8%; 95% CI [9.8, 11.7]) and ran two different multivariate models for PD. We obtained the highest PD prevalence in those affected by any mental disorder plus those reporting having suffered childhood abuse, particularly sexual abuse. Additional potential risk factors or correlates of PD identified were: younger age, lower levels of functioning, less social support, poorer general health, having suffered maltreatment, threatening life events, higher suicidal risk scores and higher levels of both neuroticism and impulsivity. CONCLUSIONS: This study reports PD prevalence and risk correlates in consonance with similar findings reported in other Western populations. However, longitudinal studies are needed to elicit a more thorough group of prospective determinants of PD.

The Affective Core of Delusional Disorder.

The aim of the present study is to investigate the relationship between personality, trait affectivity, and severity of delusions in patients with delusional disorder (DD). Thirty-two outpatients affected by DD were administered the Structured Interview for DSM-IV-TR Personality Disorders (SIDP-IV), the Pathological Narcissism Inventory (PNI), the Positive and Negative Affect Schedule (PANAS), and the Psychotic Symptom Rating Scale (PSYRATS). We analyzed the prevalence of personality disorder in our sample of patients with DD and studied the correlations between the severity of delusions and the different affective variables. Finally, we obtained a multivariate explanatory model of the severity of the delusions. The severity of delusions was directly associated with "grandiose fantasy" item of narcissistic personality and inversely related with the feelings of shame, fear, and guilt. In the multivariate model, the feeling of shame was the only independent variable capable of accounting for the severity of delusions that, in DD patients, would lie on an affective core of shame.

Estudio descriptivo del síndrome confusional agudo en Urgencias / Descriptive study of delirium in the emergency department

Objetivo: Conocer mejor las variables clínicas, funcionales y analíticas que se asocian al síndrome confusional agudo (SCA) en urgencias y la evolución de las mismas con el fin de obtener una mejora en el abordaje terapéutico del paciente anciano previniendo así la morbimortalidad en este tipo de pacientes. Diseño: Se trata de un estudio descriptivo prospectivo de SCA en urgencias. Emplazamiento: Hospital General Universitario de Ciudad Real. Participantes: Se incluyó, en el intervalo de las 24 h siguientes al ingreso en el Servicio de Geriatría, a todos los pacientes procedentes del Servicio de Urgencias con diagnóstico de SCA. Mediciones principales: Se realizó un análisis de las variables del conjunto de datos (variables sociodemográficas y clínicas), calculando tablas de frecuencias para variables de tipo cualitativo y estadísticos descriptivos para las variables cuantitativas. Posteriormente, se han empleado técnicas de inferencia estadística. Resultados: El antecedente médico más frecuente fueron la enfermedad neurológica y la HTA, seguida de las enfermedades reumatológicas. Los motivos de consulta principales fueron el deterioro del estado general, la disnea, la disminución del nivel de consciencia y la fiebre. Se debe destacar la incidencia de la polifarmacia, especialmente de fármacos como los diuréticos, benzodiacepinas o hipnóticos. En relación con la etiología principal, destaca el papel de las infecciones de tipo urinario y respiratorio. Conclusiones: Se destaca el papel fundamental de las enfermedades neurológicas (especialmente la demencia), la HTA, la polifarmacia (uso inadecuado de benzodiacepinas e hipnóticos) y las infecciones urinarias y respiratorias como factores tratables o prevenibles del delirium en el paciente de Atención Primaria en nuestro medio.(AU)

Objective: To better understand the clinical, functional and analytical variables associated with delirium in emergencies and their evolution in order to obtain an improvement in the therapeutic approach of the elderly patient, thus preventing morbidity and mortality in this type of patient. Design: This is a prospective descriptive study of acute confusional syndrome in the emergency department. Site: General University Hospital of Ciudad Real. Participants: All patients from the emergency department with a diagnosis of delirium were included in the 24-h interval following admission to the geriatric service. Main measurements: An analysis of the variables of the data set (sociodemographic and clinical variables) was performed, calculating frequency tables for qualitative variables and descriptive statistics for quantitative variables. Subsequently, statistical inference techniques have been used. Results: The most frequent medical antecedent were neurological pathology and hypertension, followed by rheumatologic diseases. The main reasons for consultation were deterioration in general condition, dyspnea, decreased level of consciousness, and fever. Highlight the incidence of polypharmacy, especially drugs such as diuretics, benzodiazepines or hypnotics. In relation to the main etiology, the role of urinary and respiratory infections is noteworthy. Conclusions: Highlight the fundamental role of neurological diseases (especially dementia), hypertension, polypharmacy (inappropriate use of benzodiazepines and hypnotics) and urinary and respiratory infections as treatable and/or preventable factors of delirium in Primary Care patients in our setting.(AU)

A systematic review of studies with clinician-rated scales on the pharmacological treatment of delusional disorder.

To collect the best available evidence and to compare the first-generation antipsychotics (FGAs) vs. the second-generation antipsychotics (SGAs) in the treatment of delusional disorder (DD). Systematic review including studies evaluating treatment response in DD using clinician-rated scales appearing in PubMed and Web of Science databases from inception till September 2019. Those studies meeting inclusion criteria were selected. Outcomes were summarized into two response categories: (1) response to treatment equal to or greater than 50% and (2) response less than 50%. Biases and quality of the studies were evaluated, and relevant data were extracted. Finally, both narrative review and quantitative synthesis were performed. The final sample included six studies (437 patients, 318 on treatment with SGAs). Antipsychotics achieved a good response in 32.3% of patients. Effectiveness differences between FGA and SGA were only marginal favouring the former. Among the most used antipsychotics, risperidone and olanzapine showed, respectively, 34.3 and 33.7% good response. Pimozide (n = 35) demonstrated a higher response rates compared with other antipsychotics. Inpatients showed the best treatment outcomes. Antipsychotics appeared to be an effective treatment in patients with DD. FGA were slightly superior to SGA. Pimozide does not seem to provide any advantage in most DD subtypes.

A Cross-Sectional Study on the Prevalence and Risk Correlates of Mental Disorders: The GRANADΣP Study.

This is a cross-sectional study of participants from a population census living in the province of Granada (Spain). A total of 1176 persons were contacted, 367 (31%) refused and 54 (6.7%) needed substitution. A final sample of 809 participants (response rate, 69.3%) were screened for mental disorder (MD) using the MINI International Neuropsychiatric Interview, a comprehensive interview validated to generate diagnoses compatible with ICD-10/DSM-4 criteria. Current (1-month) prevalence for any MD was 11.3% (95% confidence interval [CI], 9.7%-13.4%; affective 8.2%, anxiety 9.6%, psychotic 2.1%, addiction 1.8%, personality disorder 3.6%). Lifetime MD prevalence was 24.6% (95% CI, 21.6-27.6; affective 14.9%, anxiety 15.5%, psychotic 3.4%, addiction 4.4%, personality disorder 3.6%). Female sex was associated with MD, but this appeared partially due to higher levels of neuroticism among women. MD also correlated significantly with cannabis use, family history of MD, higher social adversity, higher suicide risk, poorer physical health, poorer cognitive performance, and personality problems.

A Psychopathological Comparison between Delusional Disorder and Schizophrenia.

OBJECTIVE: To contribute to a better differential clinical categorisation of delusional disorder (DD) versus schizophrenia (SZ) and to add and complete evidence from previous clinical studies of DD compared to schizophrenia. METHODS: A cross-sectional study using a clinical sample of 275 patients (132 patients with DD) was studied. Patients were consecutively attending public clinics located in urban and rural areas in both Andalusia and Catalonia (Spain). All participants met DSM-IV diagnostic criteria for either DD or SZ. Data were gathered on sociodemographics, illness duration, Barona-Index estimation of intelligence quotient (IQ), and global functioning, along with a thorough psychopathological assessment using the Positive and Negative Syndrome Scale (PANSS). Comparisons between both groups were calculated using χ2, Student t, and multivariate analysis of covariance tests. RESULTS: Patients with DD were older (mean [SD], 50.3 [14.6] years vs. 36.6 [11.1] years; t = 8.597; P ≤ 0.0001), were more frequently married (45.4% vs. 10.8%; χ2 = 38.569; P ≤ 0.0001), and had a higher mean estimated premorbid IQ (111.4 vs. 105.4; t = 2.609; P ≤ 0.01). On the other hand, SZ patients were predominantly male (71.4% vs. 48.9%; χ2 = 14.433; P ≤ 0.0001) and had greater work-related disability than DD patients (20.5% vs. 50.3%; χ2 = 19.564; P ≤ 0.001). Overall, the DD group showed a less severe PANSS psychopathology than SZ group. Thus, total mean (SD) PANSS scores for schizophrenia and delusional disorder, respectively, were 76.2 (22.4) versus 54.1 (18.4) ( t = -8.762; P ≤ 0.0001). Moreover, patients with DD showed a better global functioning than those with SZ (62.7 [13.2] vs. 51.9 [16.9]; F = 44.114; P ≤ 0.0001). CONCLUSIONS: DD is a milder and distinct disorder compared to SZ in terms of psychopathology and global functionality.

Protocolo y metodología del estudio epidemiológico de la salud mental en Andalucía: PISMA-ep / Protocol and methodology of study epidemiological mental health in Andalusia: PISMA-ep

Introducción. El presente artículo describe la metodología general de un estudio transversal cuyo principal objetivo consiste en la detección de la prevalencia de los principales trastornos mentales en Andalucía, y el estudio de sus correlatos o posibles factores de riesgo mediante una amplia muestra representativa de adultos que vive en la comunidad. Materiales y métodos. Este es un estudio transversal en el que desarrollamos un muestreo de varias fases utilizando distintos niveles de estratificación habituales y en el que teníamos como objetivo entrevistar a 4.518 participantes seleccionados al azar y representativos de las 8 provincias de la comunidad andaluza, con un enfoque de «llamada a la puerta». Como principal herramienta diagnóstica se utilizó la versión española de la entrevista neuropsiquiátrica internacional MINI, un instrumento válido de detección para el establecimiento de diagnósticos de trastorno mental compatibles con los criterios CIE-10/DSM-IV. Asimismo, se empleó una amplia batería de instrumentos para explorar la funcionalidad global, la comorbilidad médica, las características de la personalidad, la función cognitiva y la exposición a posibles factores de riesgo psicosocial. También se obtuvo una muestra de saliva para extraer ADN para un estudio de asociación genética. Entrevistadores entrenados llevaron a cabo las entrevistas, a pesar de que la mayoría de las medidas son compatibles con entrevistadores legos. Resultados. De los 5.496 hogares seleccionados inicialmente, el 70,8% (3.892) tuvieron que sustituirse por falta de respuesta (37,7%) o por no incluir a ninguna persona que cumpliese las características requeridas (33%). Así, de las nuevas 5.496 personas, a las cuales finalmente se accedió, 4.507 (83,7%) consintieron participar, completaron la entrevista y se las incluyó finalmente en el estudio (n = 4.507), mientras que 4.286 (78%) también proporcionaron una muestra de saliva. Por su parte, 989 (16,3%) rechazaron participar. Discusión. Se trata del estudio de epidemiología de salud mental más amplio desarrollado en la comunidad autónoma más grande y poblada de España (Andalucía). Las tasas de respuesta y representatividad de la muestra son bastante altas. El método empleado es muy completo para este tipo de estudios e incluye tanto valoraciones de personalidad (rasgos y trastorno) como valoración cognitiva, así como un amplio abanico de medidas de riesgo biopsicosocial (AU)

Introduction. This is the general methods describing paper of a cross-sectional study that aims to detect the prevalence of major mental disorders in Andalusia (Southern Spain), and their correlates or potential risk factors, using a large representative sample of community-dwelling adults. Materials and methods. This is a cross-sectional study. We undertook a multistage sampling using different standard stratification levels and aimed to interview 4,518 randomly selected participants living in all 8 provinces of the Andalusian region utilizing a door-knocking approach. The Spanish version of the MINI International Neuropsychiatric Interview, a valid screening instrument ascertaining ICD-10/DSM-IV compatible mental disorder diagnoses was used as our main diagnostic tool. A large battery of other instruments was used to explore global functionality, medical comorbidity, personality traits, cognitive function and exposure to psychosocial potential risk factors. A saliva sample for DNA extraction was also obtained for a sub-genetic study. The interviews were administered and completed by fully trained interviewers, despite most tools used are compatible with lay interviewer use. Results. A total of 3,892 (70.8%) of 5,496 initially attempted households had to be substituted for equivalent ones due to either no response (37.7%) or not fulfilling the required participant quota (33%). Thence, out of 5,496 eligible participants finally approached, 4,507 (83.7%) agreed to take part in the study, completed the interview and were finally included in the study (n=4,507) and 4,286 (78%) participants also agreed and consented to provide a saliva sample for DNA study. On the other hand, 989 (16.3%) approached potential participants refused to take part in the study. Discussion. This is the largest mental health epidemiological study developed in the region of Spain (Andalusia). The response rates and representativeness of the sample obtained are fairly high. The method is particularly comprehensive for this sort of studies and includes both, personality and cognitive assessments, as well as a large array of bio-psycho-social risk measures (AU)

A Systematic Review on the Pharmacological Treatment of Delusional Disorder.

BACKGROUND: Pharmacological treatment is the criterion standard in delusional disorder (DD). No second-generation antipsychotic (SGA) is specifically authorized for the treatment of DD. AIMS: To evaluate the evidence available on pharmacological treatments in adults with DD and to compare first-generation antipsychotics (FGA) versus SGA. METHODS: A systematic review on pharmacological treatment of DD following the PRISMA methodology was conducted. We selected the best evidence available and analyzed it critically assessing both, biases and quality, to finally perform a narrative and quantitative synthesis. RESULTS: The evidence available was mainly limited to observational studies and case series. There were no randomized clinical trials. Three hundred eighty-five DD cases were included (177 of which were on SGAs). Overall, antipsychotics achieved a good response in 33.6%% of the patients. As a group, FGAs showed significant superiority compared to SGAs (good response rates were 39% vs 28%, respectively). We did not find superiority of any specific antipsychotic over another. CONCLUSIONS: There is no strong evidence to make definite recommendations, although antipsychotics in general seem to be an effective treatment for DD with a slight superiority in favor of FGAs as compared with SGAs. Existent data are, albeit, scarce and specific clinical trials on DD, are strongly recommended.

Variables associated with sun protection behaviour of preschoolers.

Little research has been published on the variables associated with sun protection behaviour in preschoolers. We aimed to define variables associated with sun protection behaviour of a sample of Spanish preschoolers. A cross-sectional observational study was conducted in two stages: 1) the design and validation of the measurement instrument, and 2) its application in a final sample of 100 (60 valid questionnaires) children for bivariate and multivariate binary logistic regression analyses of the data. The sun protection behaviour of the children was most strongly associated with: parental sun protection behaviour, absence or low frequency of sunburn in parents and children, and lower parental perception of obstacles to sun protection. Other significant factors were lower phototype, younger age, shorter sun exposure times and awareness of the sun as a risk factor. The role of social communication programmes, dermatologists and other agents providing information or sun protection advice was contradictory and associated with lower sun protection in some cases. Parental sun protection, absence or lower frequency of sunburns in parents and children, lower phototype of children, knowledge about sun exposure as a risk factor, younger age and lower parental perception of obstacles to their children's sun protection were significantly associated with the sun protection of the children.
