Resumen: En atención primaria solo el dolor crónico supera a la depresión y la ansiedad en la pérdida de años de vida ajustados por calidad. Más del 70% de las personas que sufrían enfermedades mentales comunes consultaron por ello a su médico/a de familia. Sin embargo, «la regla de las mitades decrecientes» es una realidad: menos del 50% de las personas consultantes de atención primaria con enfermedades mentales comunes fueron diagnosticadas correctamente, y de ellas, menos del 50% recibieron un tratamiento (farmacológico o psicológico) adecuado, y de estas, menos del 50% fueron adherentes. Los modelos colaborativos de atención a las enfermedades mentales comunes en atención primaria han demostrado su efectividad en ensayos clínicos, pero su implementación en un contexto más general y real es difícil y su efectividad todavía es poco conocida. Se han desarrollado y validado algoritmos de riesgo para predecir el inicio y el pronóstico de las enfermedades mentales comunes en atención primaria que son útiles para su tratamiento y prevención. Existen evidencias de que las intervenciones psicológicas, psicoeducativas y de ejercicio físico son efectivas en prevención primaria, incluso en atención primaria, aunque su efecto es pequeño o moderado. Estas intervenciones tienen un gran potencial para ser escalables en las escuelas, el ámbito laboral y la atención primaria; además, cuando se administran mediante tecnologías de la información y la comunicación (p. ej., App), en programas autoguiados o mínimamente guiados, han demostrado su efectividad para el tratamiento y la prevención de las enfermedades mentales comunes. También son muy accesibles y de bajo coste, y contribuyen a la implementación masiva de estas intervenciones en diferentes contextos. Abstract: In primary health care only chronic pain surpass depression and anxiety in loss of quality-adjusted life years. More than 70% of people suffering from common mental disorders consulted their GPs for this reason. However, ‘the declining halves rule’ is a reality: less than 50% of primary care attendees with common mental disorders were correctly diagnosed, of these less than 50% received adequate treatment (pharmacological or psychological) and of these less than 50% patients were adherent. Collaborative models of common mental disorders care in primary health care have demonstrated their effectiveness through clinical trials; however, its implementation in a more general and real context is difficult and its effectiveness remains unclear. Risk algorithms have been developed and validated in primary health care to predict the onset and prognosis of common mental disorders; which are useful for their treatment and prevention. There is evidence that psychological and psychoeducational interventions (and possibly those of physical exercise) are effective for the primary prevention of common mental disorders, even in primary health care; although their effects are small or moderate. These interventions have a high potential to be scalable in schools, workplace and primary health care; in addition, when they are administered through information and communication technologies (e.g. by App), in self-guided or minimally guided programs, they have demonstrated their effectiveness for the treatment and prevention of common mental disorders. They are also very accessible, have low cost and contribute to the massive implementation of these interventions in different settings.

Frailty is an age-related clinical condition that typically involves a deterioration in the physiological capacity of various organ systems and heightens the patient’s susceptibility to stressors. For this reason, one of the main research goals currently being addressed is that of characterising the impact of frailty in different settings. The main aim of this study is to determine the prevalence of Fried’s frailty phenotype among community-dwelling older people and to analyse the factors associated with frailty. In this research study, 582 persons aged 65 years or more participated in this cross-sectional study that was conducted at primary healthcare centres in Málaga, Spain. Sociodemographic, clinical, functional and comprehensive drug therapy data were compiled. The relationship between the independent variables and the different states of frailty was analysed by using a multinomial logistic regression model. Frailty was present in 24.1% of the study sample (95% CI = 20.7–27.6) of whom 54.3% were found to be pre-frail and 21.6% were non-frail. The study variable most strongly associated with frailty was the female gender (OR = 20.54, 95% CI = 9.10–46.3). Other factors found to be associated with the state of frailty included age, dependence for the instrumental activities of daily living (IADL), polymedication, osteoarticular pathology and psychopathology. This study confirms the high prevalence of frailty among community-dwelling older people. Frailty may be associated with many factors. Some of these associated factors may be preventable or modifiable and, thus, provide clinically relevant targets for intervention. This is particularly the case for depressive symptoms, the clinical control of osteoarthritis and the use of polypharmacy.

Mental disorders are one of the greatest public health concerns of our time, and they are affected by social factors. To reduce the considerable burden of mental disorders, more global and systematic knowledge of the social determinants of mental health is necessary. This paper presents the results of the 27 studies included in the International Journal of Environmental Research and Public Health Special Issue, “Social Determinants of Mental Health”. The studies are grouped into four broad categories: social inclusion and mental health, young people’s mental health, mental health at work, and mental health service users. The results cover different countries, age populations, settings, and methodologies. Finally, the main findings on the relationship between social determinants and mental health are presented and summarized.

Although early life nutrition influences brain development and mental health, the long-term e ects of supplemented infant formula on children´s behavior remain unclear. We analyzed the e ects of a bioactive nutrients-enriched-infant formula on children’s behavior up to 2.5 years, compared to a standard infant formula or breastfeeding. Current analysis involved 70 children who were fed a standard infant formula (SF, n = 29) or a bioactive compounds enriched-infant formula (EF, n = 41), during their first 18 months of life, and 33 breastfed (BF) children (reference group) participating in the COGNIS study. Behavioral problems were evaluated using the Child Behavior Checklist at 18 months and 2.5 years. Di erent statistical analyses were performed using SPSS. EF children aged 2.5 years presented fewer pathological a ective problems than SF children. Besides, SF children were classified more frequently as bordering on internalizing problems than BF children. Rates of externalizing problems were increased in SF infants compared to EF and BF infants. Higher maternal IQ was found to have beneficial e ects on internalizing and total problem rate in their o spring at 18 months of life; finally, higher maternal educational level was related with fewer ADHD problems in children at 18 months, as well as internalizing, externalizing, total and anxiety problems in children aged 2.5 years. Our analysis suggests that enriched infant formula fed infants seem to show fewer behavioral problems up to 2.5 years compared to a standard infant formula-fed infants. In addition to type of early feeding, maternal IQ and educational level seem to play a key role on children behavioral development., Ordesa Laboratories, S.L.

Journal Article; Review; Subjective tinnitus is the perception of sound in the absence of external or bodily-generated sounds. Chronic tinnitus is a highly prevalent condition affecting over 70 million people in Europe. A wide variety of comorbidities, including hearing loss, psychiatric disorders, neurodegenerative disorders, and temporomandibular joint (TMJ) dysfunction, have been suggested to contribute to the onset or progression of tinnitus; however, the precise molecular mechanisms of tinnitus are not well understood and the contribution of genetic and epigenetic factors remains unknown. Human genetic studies could enable the identification of novel molecular therapeutic targets, possibly leading to the development of novel pharmaceutical therapeutics. In this article, we briefly discuss the available evidence for a role of genetics in tinnitus and consider potential hurdles in designing genetic studies for tinnitus. Since multiple diseases have tinnitus as a symptom and the supporting genetic evidence is sparse, we propose various strategies to investigate the genetic underpinnings of tinnitus, first by showing evidence of heritability using concordance studies in twins, and second by improving patient selection according to phenotype and/or etiology in order to control potential biases and optimize genetic data output. The increased knowledge resulting from this endeavor could ultimately improve the drug development process and lead to the preventive or curative treatment of tinnitus. Yes

Background: Most of the studies on sychological distress in Spain have been conducted in small geographical areas or specific population groups. However, there are no studies that provide representative data for each Autonomous Community (AC). The objectives of this paper are to determine, both in Spain and in the AC, the prevalence of psychological distress, diagnosis, use of psychoactive medication, social support and self-perceived health, as well as to study the association between psychological distress and the rest of the variables. Methods: Cross-sectional study, using data from the 2006 National Health Survey, that was completed by 29,478 persons. Variables studied: sociodemographics, psychological distress (GHQ-12), self-perceived health, mental disorder diagnosis, functional social support (Duke) and use and prescription of psychoactive medication. Results: The prevalence of psychological distress in Spain was 20,1%; the highest prevalence was found in Canary Islands (28,2%) and the lowest in La Rioja (12,2%). Among those who presented psychological distress, 62,4% had never received a mental disorder diagnosis, and 71,6% had not used psychoactive medication in the last year. The highest prevalences of non-diagnosed cases (81,8%) and cases non-treated with psychoactive medication (83,1%) were found in La Rioja, whereas the lowest prevalences were found in Asturias. Eight percent of the persons who presented psychological distress had low social support and 63,8% reported bad self-perceived health. Conclusions: Psychological distress is a prevalent phenomenon, and more than half of the persons who suffer it receive neither a diagnosis nor psychoactive medication. Moreover, there are considerable differences between the AC. Yes Fundamentos: En España no existe ningún estudio en el que se hayan tomado muestras representativas por Comunidades Autónomas (CCAA) para estudiar la morbilidad psíquica. Los objetivos de este trabajo son describir su prevalencia, la presencia de diagnóstico, el consumo de psicofármacos, el apoyo social y la salud autopercibida y la relación entre la morbilidad psíquica y el resto de variables, tanto a nivel nacional como de CCAA. Método: Estudio transversal. Fuente de información: Encuesta Nacional de Salud 2006, muestra 29.478 personas. Variables estudiadas: sociodemográficas, morbilidad psíquica (GHQ-12), estado de salud autopercibido, diagnóstico de trastorno mental, apoyo social funcional (Duke) y consumo y prescripción de psicofármacos. Para determinar la frecuencia se utilizó el porcentaje y los intervalos de confianza al 95%. Para estudiar la relación entre morbilidad psíquica y el resto de variables se utilizó la prueba de Chi cuadrado, considerando la significación estadística con un valor de p

Recent studies have identified biomarkers related to the severity and pathogenesis of cocaine addiction and common comorbid psychiatric disorders. Monitoring these plasma mediators may improve the stratification of cocaine users seeking treatment. Because the neurotrophic factors are involved in neural plasticity, neurogenesis and neuronal survival, we have determined plasma concentrations of brain-derived neurotrophic factor (BDNF), insulin- like growth factor 1 (IGF-1) and IGF-1 binding protein 3 (IGFBP-3) in a cross-sectional study with abstinent cocaine users who sought outpatient treatment for cocaine (n = 100) and age/body mass matched controls (n = 85). Participants were assessed with the diagnostic interview ‘Psychiatric Research Interview for Substance and Mental Disorders’. Plasma concentrations of these peptides were not different in cocaine users and controls. They were not associated with length of abstinence, duration of cocaine use or cocaine symptom severity. The pathological use of cocaine did not influence the association of IGF-1 with age observed in healthy subjects, but the correlation between IGF-1 and IGFBP-3 was not significantly detected. Correlation analyses were performed between these peptides and other molecules sensitive to addiction: BDNF concentrations were not associated with inflammatory mediators, lipid derivatives or IGF-1 in cocaine users, but correlated with chemokines (fractalkine/CX3CL1 and SDF-1/CXCL12) and N-acyl-ethanolamines (N-palmitoyl-, N-oleoyl-, N-arachidonoyl-, N-linoleoyl- and N-dihomo-γ-linolenoyl-ethanolamine) in controls; IGF-1 concentrations only showed association with IGFBP-3 concentrations in controls; and IGFBP-3 was only correlated with N-stearoyl-ethanolamine concentrations in cocaine users. Multiple substance use disorders and life-time comorbid psychopathologies were common in abstinent cocaine users. Interestingly, plasma BDNF concentrations were exclusively found to be decreased in users diagnosed with both primary and cocaineinduced disorders for mood and anxiety disorders. In summary, BDNF, IGF-1 and IGFBP-3 were not affected by a history of pathological use of cocaine supported by the absence of associations with other molecules sensitive to cocaine addiction. However, BDNF was affected by comorbid mood disorders. Further research is necessary to elucidate the role of BDNF and IGF-1 in the transition to cocaine addiction and associated psychiatric comorbidity, The present study has been supported by Instituto de Salud Carlos III (ISC-III), Red de Trastornos Adictivos UE-FEDER 2012 (RD12/0028); Ministerio de Economía y Competitividad (PI13/ 02261); Plan Nacional sobre Drogas 049/2009 and 049/2013; Consejería de Economía, Innovación y Ciencia, Junta de Andalucía UE-FEDER (CTS-433); Consejería de Salud y Bienestar Social, Junta Andalucía (PI0228-2013 and PI0823-2012); Departament d’Innovació, Universitats i Empresa, Generalitat de Catalunya (2014-SGR-680).

The association between mental disorders (MDs) and iatrogenic complications after hip fracture surgery has been poorly studied. Among iatrogenic complications, nosocomial infections (NIs) are a major factor in hip fracture surgery. The aim of this paper was to determine whether patients with a MD and a hip fracture develop more NIs after hip surgery than patients with no MD. We studied 912 patients who underwent surgery for a hip fracture (223 patients with a MD who underwent surgery for a hip fracture and 689 control patients without a MD who also underwent surgery for a hip fracture) and followed them after surgery. Univariable and multivariable analyses were performed using simple and multiple logistic regression analysis (confidence interval, crude and adjusted odds ratios, andPvalue). We found that MDs, gender, and comorbidities were not associated with a higher risk of developing a NI after surgery for a hip fracture. Only age increases the risk of a NI.

Background Periods of financial crisis are associated with higher psychological stress among the population and greater use of mental health services. The objective is to analyse contextual factors associated with mental health among the Spanish population during the recession. Methodology Cross-sectional, descriptive study of two periods: before the recession (2006) and after therecession (2011-2012). The study population comprised individuals aged 16+ years old, polled for the National Health Survey. There were 25,234 subjects (2006) and 20,754 subjects (2012). The dependent variable was psychic morbidity. Independent variables: 1) socio-demographic (age, socio-professional class, level of education, nationality, employment situation, marital status), 2) psycho-social (social support) and 3) financial (GDP per capita, risk of poverty, income per capita per household), public welfare services (health spending per capita), labour market (employment and unemployment rates, percentage of temporary workers). Multilevel logistic regression models with mixed effects were constructed to determine change in psychic morbidity according to the variables studied. Results The macroeconomic variables associated with worse mental health for both males and females were lower health spending per capita and percentage of temporary workers. Among women, the risk of poor mental health increased 6% for each 100€ decrease in healthcare spending per capita. Among men, the risk of poor mental health decreased 8% for each 5-percentage point increase in temporary workers. Conclusions Higher rates of precarious employment in a region have a negative effect on people’s mental health; likewise lower health spending per capita. Policies during periods of recession should focus on support and improved conditions for vulnerable groups such as temporary workers. Healthcare cutbacks should be avoided in order to prevent increased prevalence of poor mental health.
