Perfil sociodemográfico e saúde mental em cuidadores informais de idosos no município de São Paulo-Brasil: desafios para as políticas públicas

RESUMO: INTRODUÇÃO: O rápido envelhecimento populacional, o aumento da prevalência de transtornos neuropsiquiátricos, o aumento das taxas de morbilidade clínica e incapacidade entre idosos de países em desenvolvimento têm trazido preocupações sobre a saúde mental e sobrecarga de cuidadores informais. Está bem estabelecida a elevada prevalência de transtornos mentais comuns (TMC) associada à adversidade socioeconômica, baixo nível educacional, estresse e gênero. Idosos e cuidadores vivendo em comunidade compartilham fatores de risco para morbilidade física e psiquiátrica. Adicionalmente, os cuidadores tem uma tripla carga, sendo simultaneamente familiares, trabalhadores leigos em saúde sem suporte dos serviços de saúde e assistência social e um paciente com necessidades não atendidas. O cuidador informal é o principal provedor de cuidado em todos os países. OBJETIVOS: Acessar perfil sociodemográfico, níveis de transtorno mental comum (TMC) e sobrecarga em cuidadores, características do cuidado e prevalência de demência e depressão no idosos, numa área carente da região oeste de São Paulo –Brasil. MÉTODO: Esta pesquisa transversal deriva do São Paulo Ageing and Health Study (SPAH) que incluiu idosos com 65 anos ou mais e seus respectivos cuidadores. Os participantes foram identificados por arrolamento domiciliar e entrevistadas em suas casas com protocolo padronizado de pesquisa. O instrumento utilizado para acessar os transtornos mentais comuns, foi o Self Rating Questionnaire SRQ-20.A sobrecarga foi quantificada pelo Zarit Caregiver Burden Scale. Diagnósticos psicogeriátricos foram mensurados através do SRQ-20 e critérios do CID-10 e do DSM-IV. 8 RESULTADOS: 588 cuidadores e respectivos idosos foram incluídos. Nos idosos, a prevalência de demência foi 15,9%, de depressão pelo CiD-10 9.9% e de TMC 39,25% Nos cuidadores, a prevalência de TMC foi de 55,1% e 32,8% dos cuidadores apresentaram sobrecarga elevada. O perfil do cuidador foi filha,com idade em torno dos 49 anos, casada e com baixo nível educacional.------------------ABSTRACT: BACKGROUND: With the fast population aging, growing prevalence of neuropsychiatric disorders, clinical morbidity and disability among the elderly particularly in low income countries (LAMIC), has brought concerns about informal caregiver Mental Health and Burden. It is well established the high prevalence of Common Mental Disorders (CMD) associated to socioeconomic adversity, low educational attainment, stress and gender. Community-dwelling elders and caregivers share risk factors for physical and psychiatric morbidity. In addition, caregivers have a triple strain, being simultaneously, family members, lay health workers with lack of support from health and social work services and a hidden patient with unmet needs. The world main source of caregiving relies on informal caregiver. AIMS: To assess 1) the sociodemographic profile, levels of CMD and burden among caregivers, and 2) the characteristics of care and prevalence of dementia and depression in elderly in a socioeconomic underprivileged area in western region of Sao Paulo – Brazil. METHOD: The present investigation is a cross-sectional part of Sao Paulo Ageing and Health Study (SPAH) which included participants aged 65 or older and their respective caregivers. Participants were identified by household enrollment and interviewed in their homes using a standardized research protocol. The assessment of common mental disorders was performed with the Self Rating Questionnaire – 20 (SRQ-20), used to establish psychiatric caseness. The assessment of burden was performed with Zarit Caregiver Burden Scale. Dementia and psychogeriatric diagnosis were reached through ICD-10, SRQ-20 and DSM-IV criteria. 10 RESULTS: 588 caregivers and respective elderly relatives were included. Prevalence of dementia was 15.9%, ICD-10 depression 9.9% and CMD 39.3% among the elderlys. Common mental disorder prevalence in caregivers was 55.1% and high burden was reached in 32.8% of the caregiver sample. Most of the caregivers were married and co-resident daughters with a mean age of 49 years (CI 95% - 48.7 to 51).

Resilienz bei Rehabilitanden der Orthopädie und Psychosomatik : Eine Querschnittstudie

Theoretical background: The construct of resilience is now used in many fields, such as in sports, corporate governance and in health care system. Against the backdrop of the unique system of rehabilitation in Germany, that empowers people to participate in a social and pro-fessional way, the concept of resilience is becoming increasingly important. Accordingly this cross-sectional study should explore the resilience of orthopedic and psychosomatic patients in more detail.Questions: Are there differences in the sample that lead to different sub-samples based on the RS-13? Are there differences between the sub-samples in terms of socio-demographic data, psychosocial problems, psychological stress, stress in the workplace and the experi-ence of stress? Do socio-demografic, employment, psycho-social and psychological varia-bles influence resilience?Method: For this investigation the data of n = 131 patients was used. The data was collected in an orthopedic clinic of rehabilitation and in a psychosomatic clinic of rehabilitation. On the basis of the results of the short Resiliencescale RS-13 the sample was split into two sub-samples of N1 = 51 patients with low resilience and N2 = 80 patients with higher resilience. The questions were examined by regarding the Brief Symptom Checklist (BSCL), the Ultra-Kurz-Screening (UKS), the Stressscale (from the DASS-Questionnaire) and the Employee Attitude Survey (BAuA). Additionally a literature research was done in databases like Psy-Content, Psyndex and Springerlink to acquire the theoretical background.Results: Within the sample, there were two sub-samples, one which included patients with low resilience while the other was characterized by high resilience. Patients with low resili-ence did not differ by considering the variables of age, sex, marital status, children, educa-tion, occupational status, industry and job stress. Patients with high resilience are older and rarer incap

Detection of neuronal activity and metabolism in a model of dehydration-induced anorexia in rats at 14.1 T using manganese-enhanced MRI and 1H MRS.

In this study, hypothalamic activation was performed by dehydration-induced anorexia (DIA) and overnight food suppression (OFS) in female rats. The assessment of the hypothalamic response to these challenges by manganese-enhanced MRI showed increased neuronal activity in the paraventricular nuclei (PVN) and lateral hypothalamus (LH), both known to be areas involved in the regulation of food intake. The effects of DIA and OFS were compared by generating T-score maps. Increased neuronal activation was detected in the PVN and LH of DIA rats relative to OFS rats. In addition, the neurochemical profile of the PVN and LH were measured by (1) H MRS at 14.1T. Significant increases in metabolite levels were measured in DIA and OFS relative to control rats. Statistically significant increases in γ-aminobutyric acid were found in DIA (p=0.0007) and OFS (p<0.001) relative to control rats. Lactate increased significantly in DIA (p=0.03), but not in OFS, rats. This work shows that manganese-enhanced MRI coupled to (1) H MRS at high field is a promising noninvasive method for the investigation of the neural pathways and mechanisms involved in the control of food intake, in the autonomic and endocrine control of energy metabolism and in the regulation of body weight.

In vitro activity of gallium maltolate against Staphylococci in logarithmic, stationary, and biofilm growth phases: comparison of conventional and calorimetric susceptibility testing methods.

Ga(3+) is a semimetal element that competes for the iron-binding sites of transporters and enzymes. We investigated the activity of gallium maltolate (GaM), an organic gallium salt with high solubility, against laboratory and clinical strains of methicillin-susceptible Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), methicillin-susceptible Staphylococcus epidermidis (MSSE), and methicillin-resistant S. epidermidis (MRSE) in logarithmic or stationary phase and in biofilms. The MICs of GaM were higher for S. aureus (375 to 2000 microg/ml) than S. epidermidis (94 to 200 microg/ml). Minimal biofilm inhibitory concentrations were 3,000 to >or=6,000 microg/ml (S. aureus) and 94 to 3,000 microg/ml (S. epidermidis). In time-kill studies, GaM exhibited a slow and dose-dependent killing, with maximal action at 24 h against S. aureus of 1.9 log(10) CFU/ml (MSSA) and 3.3 log(10) CFU/ml (MRSA) at 3x MIC and 2.9 log(10) CFU/ml (MSSE) and 4.0 log(10) CFU/ml (MRSE) against S. epidermidis at 10x MIC. In calorimetric studies, growth-related heat production was inhibited by GaM at subinhibitory concentrations; and the minimal heat inhibition concentrations were 188 to 4,500 microg/ml (MSSA), 94 to 1,500 microg/ml (MRSA), and 94 to 375 microg/ml (MSSE and MRSE), which correlated well with the MICs. Thus, calorimetry was a fast, accurate, and simple method useful for investigation of antimicrobial activity at subinhibitory concentrations. In conclusion, GaM exhibited activity against staphylococci in different growth phases, including in stationary phase and biofilms, but high concentrations were required. These data support the potential topical use of GaM, including its use for the treatment of wound infections, MRSA decolonization, and coating of implants.

Motorcycle helmets: what about their coating?

In traffic accidents involving motorcycles, paint traces can be transferred from the rider's helmet or smeared onto its surface. These traces are usually in the form of chips or smears and are frequently collected for comparison purposes. This research investigates the physical and chemical characteristics of the coatings found on motorcycles helmets. An evaluation of the similarities between helmet and automotive coating systems was also performed.Twenty-seven helmet coatings from 15 different brands and 22 models were considered. One sample per helmet was collected and observed using optical microscopy. FTIR spectroscopy was then used and seven replicate measurements per layer were carried out to study the variability of each coating system (intravariability). Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) were also performed on the infrared spectra of the clearcoats and basecoats of the data set. The most common systems were composed of two or three layers, consistently involving a clearcoat and basecoat. The coating systems of helmets with composite shells systematically contained a minimum of three layers. FTIR spectroscopy results showed that acrylic urethane and alkyd urethane were the most frequent binders used for clearcoats and basecoats. A high proportion of the coatings were differentiated (more than 95%) based on microscopic examinations. The chemical and physical characteristics of the coatings allowed the differentiation of all but one pair of helmets of the same brand, model and color. Chemometrics (PCA and HCA) corroborated classification based on visual comparisons of the spectra and allowed the study of the whole data set at once (i.e., all spectra of the same layer). Thus, the intravariability of each helmet and its proximity to the others (intervariability) could be more readily assessed. It was also possible to determine the most discriminative chemical variables based on the study of the PCA loadings. Chemometrics could therefore be used as a complementary decision-making tool when many spectra and replicates have to be taken into account. Similarities between automotive and helmet coating systems were highlighted, in particular with regard to automotive coating systems on plastic substrates (microscopy and FTIR). However, the primer layer of helmet coatings was shown to differ from the automotive primer. If the paint trace contains this layer, the risk of misclassification (i.e., helmet versus vehicle) is reduced. Nevertheless, a paint examiner should pay close attention to these similarities when analyzing paint traces, especially regarding smears or paint chips presenting an incomplete layer system.

Comparative lifecycle assessment on organic and conventional carrots – case: Carrots from South-Savo and imported carrots from Italy

Organic farming is perceived to be an environmental friendly method of food production, thus assumed to be an alternative means of minimizing food-based environmental footprints. However, lower yield and unproductive years in organic crop rotation raise questions of whether it is really an environmentally friendly farming practice. Thus, the aim of this thesis was to examine the carbon footprint and energy demands of organic carrots cultivated and sold in South-Savo, Finland and compare them with those of local and imported conventional carrots using lifecycle assessment (LCA) as a method. From the investigation, it was found that organic carrots produced in South-Savo have the lowest GHG emissions and energy demand. The GHG emissions of local organic, local conventional and imported conventional carrots were found to be 4g CO2 eq. kgcarrots-1, 142g CO2 eq. kgcarrots-1 and 280 g CO2 eq. kgcarrots-1, respectively. On the other hand, energy demand for those carrots was found to be 1,33 MJ, 1,88 MJ and 3,68 MJ kgcarrots-1. Furthermore, it was also found that local organic carrots would have approximately similar GHG emissions as conventional counterpart if soil carbon stock change was excluded from the study.

L'articulation entre le rapport de Socrate aux dieux et son rapport à la raison : le cas du signe divin

À très peu de philosophes l’histoire de la pensée occidentale a accordé une place aussi significative qu’à Socrate : nous apprenons tout naturellement à l’édifier comme héros de la rationalité et à reconnaître en lui la figure même du philosophe critique. À plusieurs égards, cette représentation élogieuse nous paraît justifiée, bien que, d’un autre point de vue, elle puisse nous faire sombrer dans la confusion, dès lors que notre regard porte simultanément, et comme pour produire un contraste, sur l’image d’un Socrate se soumettant au daimonion, son étrange signe divin. Comment pouvons-nous justifier, à partir du corpus platonicien, à la fois l’engagement de Socrate vis-à-vis de la rationalité et sa soumission à un phénomène en apparence irrationnel ? De cette question troublante est née la présente étude qui se consacre donc au problème de l’articulation entre le rapport de Socrate aux dieux et son rapport à la raison critique. Plus précisément, nous avons cherché à déterminer s’il existait, sur le plan épistémologique, une hiérarchie entre le daimonion et la méthode d’investigation rationnelle propre à Socrate, l’elenchos. Une telle étude exégétique nécessitait, dans un premier temps, une analyse systématique et approfondie des quelques passages sur le signe divin. Nous avons ensuite exposé deux solutions paradigmatiques au problème du double engagement contradictoire de Socrate, celle de G. Vlastos ainsi que celle de T.C. Brickhouse et N.D. Smith. Enfin, nous avons augmenté cette seconde partie d’un examen spécifique du Phèdre et du Timée, de même que d’un survol des modes de divination pour satisfaire un triple objectif : situer le signe divin en regard de la mantique traditionnelle, déterminer le rôle attribué par Platon à la raison dans le processus divinatoire, et être ainsi en mesure de trancher notre question principale.

Descripción de los casos de accidentes laborales ocurridos en una empresa manufacturera, 2010 al 2014

Introducción Debido a que los accidentes de origen ocupacional ocupan un lugar importante dentro de las causas de ausentismo, discapacidades y hasta las muertes se realizó la descripción de la accidentalidad, teniendo en cuenta factores como la severidad y tipo de lesión, el tipo de actividad laboral y re accidentalidad ocurrida en una empresa manufacturera en un periodo de 2010 al 2014. Objetivos Establecer la distribución de los accidentes laborales ocurridos en una empresa manufacturera en el periodo de 2010 al 2014 según edad, género, área laboral y tipo de lesión. Materiales y métodos Se realizó un estudio de corte transversal en donde se analizaron las características según los trabajadores y la empresa y se realizaron asociaciones para establecer cuáles eran los factores de riesgo para presentar re accidentalidad. Se tomó una empresa manufacturera del sector de producción de alimentos que cuenta con un total de 950 empleados, en riesgo de presentar accidentes laborales. Se seleccionaron 338 accidentes ocurridos en el periodo de 2010 y 2014.Se realizaron análisis de los accidentes según las variables de: género, área de trabajo y tipo de herida para determinar su distribución según dichos factores. Posteriormente se realizaron análisis bivariado por medio de asociaciones estadísticas usando el estadístico Chi cuadrado y pruebas no paramétricas o paramétricas según la distribución de normalidad de las variables cuantitativas. El programa que se usó para el análisis fue el de SPSS versión 22. Resultados El estudio identificó que la proporción de accidentes durante el periodo estudiado con respecto al número de trabajadores fue de 35,6% y de los 950 trabajadores el 28,8% presentaron accidentes que corresponde a los 274 trabajadores. La mediana de edad fue de 35 años y se presentó más frecuente en mujeres (55,6%). El área laboral en la que se presentaron mayor número de accidentes fue el área de manufactura (75,7%). La proporción de mujeres que presentaban mayor accidentes en el área de manufactura si representó una diferencia de 23,4% con respecto a la proporción de hombres que presentaron mayor accidentes en la misma área. Con respecto al tipo de lesión, se presentaron accidentes frecuentemente en miembros superiores y según el género, las mujeres presentaron 2,02% más accidentes en miembros superiores comparado con los hombres. Los análisis en cuanto a re accidentalidad determinaron que el 16,8% de los trabajadores presentaron más de un accidente y un trabajador presentó 5 accidentes en el periodo de tiempo estudiado en la empresa, la edad se relacionó significativamente con el hecho de presentar re accidentalidad.

Análise de barreiras e o modelo de ressonância funcional de acidentes de Erik Hollnagel

Partindo de apresentação da proposta de análise de acidentes baseada no modelo sistêmico e não linear de acidentes, dito de ressonância funcional, desenvolvido por Erik Hollnagel, este texto discute críticas às concepções deterministas de acidente e aos modelos lineares de representação desses eventos. Aspectos do modelo de ressonância funcional são usados como eixo definidor de proposta de agenda de discussões a ser desenvolvida pelos interessados no tema da análise de acidentes, destacando-se: a) a defesa do abandono da idéia de causas de acidentes e sua substituição pela de explicação desses eventos; b) apresentação dos conceitos de variabilidade de desempenhos e adaptações locais e a proposta de sua utilização como bases para a identificação de perfis ou aspectos típicos de acidentes. Por fim, discute-se a necessidade de incorporação dos conceitos apresentados no debate sobre novos caminhos para as práticas de análises e de prevenção de acidentes em nosso país.

Culpa da vítima: um modelo para perpetuar a impunidade nos acidentes do trabalho

Neste artigo analisam-se os laudos e dados obtidos das investigações de acidentes graves e fatais do trabalho efetuadas pelo Instituto de Criminalística (IC), Regional de Piracicaba. Foram analisados 71 laudos de acidentes ocorridos em 1998, 1999 e 2000. Os acidentes envolvendo máquinas representam 38,0%, seguido pelas quedas de altura (15,5%) e em terceiro lugar os causados por corrente elétrica (11,3%). Os laudos concluem que 80,0% dos acidentes são causados por atos inseguros cometidos pelos trabalhadores, enquanto que a falta de segurança ou condição insegura responde por 15,5% dos casos. A responsabilização das vítimas ocorre mesmo em situações de elevado risco em que não são adotadas as mínimas condições de segurança, com repercussão favorável ao interesse dos empregadores. Observa-se que estas conclusões refletem os modelos explicativos tradicionais, reducionistas, em que os acidentes são fenômenos simples, de causa única, centrada via de regra nos erros e falhas das próprias vítimas. A despeito das críticas que tem recebido nas duas últimas décadas no meio técnico e acadêmico, esta concepção mantém-se hegemônica prejudicando o desenvolvimento de políticas preventivas e a melhoria das condições de trabalho.
