Tuning the optical properties of luminescent down shifting layers based on organic dyes to increase the efficiency and lifetime of P3HT: PCBM photovoltaic devices

Mixtures of luminescence downshifting (LDS) materials has been used to increase the efficiency of poly(3-hexylthiophene-2,5-diyl):phenyl-C61-butyric acid methyl ester (P3HT:PC61BM) bulk heterojunction solar cell. This layers convert more energetic photons to lower energies that are better matched with wavelength peak of the external quantum efficiency (EQE) of a P3HT:PC61BM solar cell. Experimental studies were used to optimise the optical properties of LDS layers including the maximum of absorbance and the photoluminescence quantum yield (PLQY). To provide the significant improvements, combinations of LDS mixtures were prepared to provide the greatest absorption and PLQY. The approach is shown to simultaneously improve the photocurrent and increase the lifetime of the device by absorbing UV light. By optimising the optical properties of the LDS mixture, a relative increase of about 20% in the photocurrent density produced by the P3HT:PCBM cell could be achieved, which to our knowledge is one of the most significant reported for OPVs

Níveis lipêmicos e alguns fatores de risco de doenças cardiovasculares em população do Município de São Paulo, SP (Brasil)

An attempt was made to caracterize lipemic levels according to sex, age and presence or absence of cardiovascular disease risk factors, in a population of 3,792 people between the ages of 20 and 59, in terms of smoking habits, obesity, family history of diabetes and use of oral contraceptives. Those individuals who did not present any of the risk factors mentioned were classified as "exempt". After submitting the data to variance analysis it was found that: - for men between 20 and 49 years of age there were high significant differences in the averages obtained for the seric levels of total lipids, triglycerides and total cholesterol between "exempt" and obese and "exempt" and obese with a family history of diabetes; - for the 50 to 59 age group there were significant differences in the average of the values corresponding to the seric levels of total lipids between "exempt" and those individuals in whom obesity appeared associated with smoking habits or associated with a family history of diabetes. The averages obtained for seric triglycerides were significantly different between "exempt" and non-obese with a family history of diabetes, obese, obese smokers and obese with a family history of diabetes. On the other hand, the averages relating to seric levels of total cholesterol were different, at significant levels, between "exempt" and obese smokers; - the risk represented by the smoking habit showed no relevance with regard to the lipemic levels in any group except for that of men between 30 and 39 years of age. In their case, there were significant differences between the averages obtained for the seric levels of total lipids, triglycerides and total cholesterol, between "exempt" and smokers and between "exempt" and obese smokers. It is to be noted that the differences obtained with regard to the averages relating to lipemic levels as between "exempt" and obese were less those obtained between "exempt" and obese smokers, thus showing the possible relevance of the risk presented by the smoking habit; - among the women there were less accentuated differences in the averages corresponding to the lipemic levels as between "exempt" and those who presented one or more risk factors. Thus, for the age group from 20 to 29 there were significant differences in the averages obtained for total lipids as between "exempt" and obese. The averages of the serie levels of total cholesterol were significantly different as between "exempt" and obese and between "exempt" and obese with a family history of diabetes, irrespective of their smoking; - for the age group from 30 to 39, there were significant differences in the averages obtained for the serie levels of triglycerides as between "exempt" and obese. The averages relating to serie levels of total cholesterol were significantly different as between "exempt" and obese and between "exempt" and those who used oral contraceptives; - for the age group between 50 and 59, the lipemic levels were high, especially those of total cholesterol, for all groups, irrespective of risk factors; - for all age groups, of both sexes, obesity was the most important risk factor.No estudo de população constituída de 3.792 indivíduos, procurou-se caracterizar o estado dos níveis lipêmicos, segundo sexo, idade e a presença ou ausência de fatores de risco de doenças cardiovasculares, expressos pelo hábito de fumar, obesidade, antecedentes diabéticos e uso de contraceptivos orais. Os indivíduos que não apresentaram nenhuma patologia e qualquer dos fatores de risco considerados foram denominados "isentos". Os dados foram submetidos à análise de variância constatando-se que a obesidade apresentou-se como o fator de risco mais relevante, para todos os grupos etários de ambos os sexos. Entretanto, para as mulheres encontraram-se diferenças menores, embora significantes, ao se comparar as médias dos níveis séricos lipêmicos, entre "isentas" e portadoras de fatores de risco. Para o grupo etário acima de 50 anos, sexo feminino, os níveis lipêmicos foram altos independentemente dos fatores de risco abordados

Desempenho ocupacional de indivíduos com osteoartrite de mão /Occupational performance of individuals with hand osteoarthritis

Introdução: A osteoartrite de mãos pode provocar prejuízos na função manual e limitar a participação em ocupações significativas. O conhecimento desse impacto é importante para direcionar a assistência às pessoas acometidas, através de abordagens que favoreçam seu desempenho ocupacional. Objetivo: Descrever a influência da osteoartrite de mãos no desempenho ocupacional de indivíduos com a doença. Métodos: Estudo transversal e descritivo, realizado no ambulatório de reumatologia de um hospital de referência, entre novembro de 2014 e maio de 2015. Foram utilizados para a coleta de dados: ficha de avaliação inicial e Medida Canadense de Desempenho Ocupacional (COPM). Para análise dos dados utilizou-se estatística descritiva, através de medidas de tendência central e distribuição de probabilidade. Resultados: Participaram do estudo 28 pacientes. As áreas de desempenho ocupacional com maior comprometimento foram a produtividade e o autocuidado, sendo identificadas com maior frequência tarefas domésticas e do vestuário. Os participantes apresentaram média de desempenho de 3,6 e satisfação de 2,9 nas atividades relatadas. Não houve relação entre o tempo de diagnóstico e o comprometimento no desempenho ocupacional. Conclusão: O impacto da osteoartrite de mãos no desempenho ocupacional reflete prejuízos nas atividades e ocupações nas áreas da produtividade, autocuidado e lazer. AbstractIntroduction: The hand osteoarthritis may cause impairments in hand function and limit the performance of several activities, restricting participation in meaningful occupations.  The knowledge of this impact is essential to direct assistance to affected people through approaches that benefit their occupational performance.

Proximal correlates of metabolic phenotypes during ‘at-risk' and ‘case' stages of the metabolic disease continuum

Extent: 11p.OBJECTIVE: To examine the social and behavioural correlates of metabolic phenotypes during ‘at-risk’ and ‘case’ stages of the metabolic disease continuum. DESIGN: Cross-sectional study of a random population sample. PARTICIPANTS: A total of 718 community-dwelling adults (57% female), aged 18--92 years from a regional South Australian city. MEASUREMENTS: Total body fat and lean mass and abdominal fat mass were assessed by dual energy x-ray absorptiometry. Fasting venous blood was collected in the morning for assessment of glycated haemoglobin, plasma glucose, serum triglycerides, cholesterol lipoproteins and insulin. Seated blood pressure (BP) was measured. Physical activity and smoking, alcohol and diet (96-item food frequency), sleep duration and frequency of sleep disordered breathing (SDB) symptoms, and family history of cardiometabolic disease, education, lifetime occupation and household income were assessed by questionnaire. Current medications were determined by clinical inventory. RESULTS: 36.5% were pharmacologically managed for a metabolic risk factor or had known diabetes (‘cases’), otherwise were classified as the ‘at-risk’ population. In both ‘at-risk’ and ‘cases’, four major metabolic phenotypes were identified using principal components analysis that explained over 77% of the metabolic variance between people: fat mass/insulinemia (FMI); BP; lipidaemia/lean mass (LLM) and glycaemia (GLY). The BP phenotype was uncorrelated with other phenotypes in ‘cases’, whereas all phenotypes were inter-correlated in the ‘at-risk’. Over and above other socioeconomic and behavioural factors, medications were the dominant correlates of all phenotypes in ‘cases’ and SDB symptom frequency was most strongly associated with FMI, LLM and GLY phenotypes in the ‘at-risk’. CONCLUSION: Previous research has shown FMI, LLM and GLY phenotypes to be most strongly predictive of diabetes development. Reducing SDB symptom frequency and optimising the duration of sleep may be important concomitant interventions to standard diabetes risk reduction interventions. Prospective studies are required to examine this hypothesis.MT Haren, G Misan, JF Grant, JD Buckley, PRC Howe, AW Taylor, J Newbury and RA McDermot
