Health care utilization among immigrants and native-born populations in 11 European countries. Results from the Survey of Health, Ageing and Retirement in Europe

This study examines health care utilization of immigrants relative to the native-born populations aged 50 years and older in eleven European countries. Methods. We analyzed data from the Survey of Health Aging and Retirement in Europe (SHARE) from 2004 for a sample of 27,444 individuals in 11 European countries. Negative Binomial regression was conducted to examine the difference in number of doctor visits, visits to General Practitioners (GPs), and hospital stays between immigrants and the native-born individuals. Results: We find evidence those immigrants above age 50 use health services on average more than the native-born populations with the same characteristics. Our models show immigrants have between 6% and 27% more expected visits to the doctor, GP or hospital stays when compared to native-born populations in a number of European countries. Discussion: Elderly immigrant populations might be using health services more intensively due to cultural reasons.

Health of Immigrants in European countries

The health of older immigrants can have important consequences for needed social support and demands placed on health systems. This paper examines health differences between immigrants and the nativeborn populations aged 50 years and older in 11 European countries. We examine differences in functional ability, disability, disease presence and behavioral risk factors, for immigrants and non-immigrants using data from the Survey of Health, Aging and Retirement in Europe (SHARE) database. Among the 11 European countries, migrants generally have worse health than the native population. In these countries, there is a little evidence of the “healthy migrant” at ages 50 years and over. In general, it appears that growing numbers of immigrants may portend more health problems in the population in subsequent years.

Fritz Feigl: sua obra e novos campos tecno-científicos por ela originados

Fritz Feigl's scientific legacy of more than 500 original publications of spot reactions and new chemical concepts, includes a precise definition of identification limit, the difference between specific and selective reactions, and the masking/demasking of chemical reactions, the selective functionalization for the development of new reactions. It resulted in a considerable and varied number of new applications evident in hundreds of citations of his publications, up to 2003, throughout the thirty years following his passing away, and comprehending scientific as well as commercial fields, like that of kits for exploratory tests, based on his reactions and of his followers.

Impacto do acordo de cooperação do Conselho Nacional de Pesquisas (CNPq) com a National Academy of Sciences - (NAS)

In the beginning of the 1960's, the university education in chemistry, in Brasil, represented only a professional preparation, with no official post-graduate teaching and research, as yet. The name Federal University Rio de Janeiro, evolved, since January 30, 1959, from University of Brazil, RJ, to Federal University of Guanabara, which, on August 20, 1965, became the Federal University of Rio de Janeiro. With the Resolution nº 4, of the University direction, the first Institute of Chemistry was created, to include the Centers of Mathematical and Natural Sciences, and the Medical Sciences. The strictu sensu's system was established only in 1961.

Líquido iônico [bmim.PF6] como solvente: um meio conveniente para estudos por fotólise por pulso de laser

The spectroscopic behavior of thioxanthone and benzil (diphenylethanedione or dibenzoyl) in the ionic liquid [bmim.PF6] has been investigated employing the laser flash photolysis technique. Triplet-triplet absorption spectra for these carbonyl compounds in [bmim.PF6] are similar to those observed in organic solvents. The triplet lifetime for thioxanthone in desogygenated samples is very long (71 μs), whereas in oxygen-saturated solution is 500 ns, which indicates the low oxygen solubility in this solvent. For benzil, lifetimes of 10 μs in [bmim.PF6] and 3.8 μs in acetonitrile were obtained. The decay for triplet thioxanthone and benzil follows a clear first order kinetics in [bmim.PF6], from which one can conclude that triplet-triplet annihilation is not an important decay process in this solvent.

Bioconcentração e biomagnificação de metilmercúrio na baía de Guanabara, Rio de Janeiro

Methylmercury was determined in water and aquatic biota from Guanabara Bay. Trophic transfer of methylmercury was observed between trophic levels from prey (microplankton, mesoplankton and fish with different feeding habits) to top predator (pelagic demersal fish). Top predator fish presented the highest methylmercury concentrations (320.3 ± 150.7 mg kg-1 dry wt.), whereas microplankton presented the lowest (8.9 ± 3.3 mg kg-1 dry wt.). The successive amplification of methylmercury concentrations and its bioconcentration factor with increasing trophic levels from base to top indicate that biomagnification may be occurring along the food web. Results suggest the importance of feeding habits and trophic level in the bioaccumulation of methylmercury by aquatic biota.

Determinação da constante de velocidade absoluta para a reação de abstração de hidrogênio fenólico pelo estado excitado triplete de xantona em acetonitrila e no líquido iônico hexafluorfosfato de 1-butil-3-metil-imidazólio [bmim.PF6]

The triplet excited state of xanthone was generated and characterized by laser flash photolysis in acetonitrile (λmax=620 nm; t=1.8 ms) and in ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate [bmim.PF6] (λmax=620 nm; t=3.0 ms). It reacts with phenols yielding the corresponding xanthone ketyl radical. Stern-Volmer plots for the reaction of triplet xanthone with phenols led to the determination of absolute rate constants for phenolic hydrogen abstraction in the order of ~10(9) Lmol-1s-1 in acetonitrile and ~10(8) Lmol-1s-1 in [bmim.PF6]. The lower diffusioncontrolled rate constant for [bmim.PF6] is responsible for the difference in the phenolic hydrogen abstraction rate constants in this solvent.

Cariologia Baseada em Evidências eo Processo Ensino-Aprendizagem

Considerando o conceito de Odontologia Baseada em Evidências, discute-se o embasamento de acadêmicos e profissionais neste paradigma, como alicerce de sua prática clínica, e alguns pontos críticos do processo ensino-aprendizagem em Odontologia. Objetivos Verificar a opinião de acadêmicos e profissionais acerca de tópicos relevantes inerentes à cariologia e ao ensino-aprendizagem. Métodos Aplicou-se questionário elaborado em Escala Likert aos acadêmicos da Faculdade de Odontologia da Universidade Federal de Mato Grosso do Sul (Faodo-UFMS) e especialistas em Dentística e Odontopediatria de Campo Grande (MS) com até 15 anos de formados.Os dados obtidos foram tabulados e submetidos a análise estatística analítica. Resultados A maior porcentagem dos estudantes expressou opinião condizente com as atuais evidências em cariologia, e os profissionais mostraram conhecimento em todas. A maioria concordou em que o método de avaliação desestimula os acadêmicos a realizar procedimentos preventivos e que nem sempre o processo ensino-aprendizagem considerou a tomada de decisão clínica alicerçada em evidências científicas. Conclusão A prática clínica dos respondentes, de modo geral, condiz com as atuais evidências, contemplando o paradigma da mínima intervenção, mas o processo ensino-aprendizagem na Faodo-UFMS poderia ser discutido e reavaliado.

Distribuição espacial da matéria orgânica, grau de floculação e argila dispersa em água em área de vegetação natural em regeneração e pastagem

Este experimento objetivou analisar as alterações no comportamento espacial dos atributos do solo: matéria orgânica (MO), argila dispersa em água (ADA) e grau de floculação (GF) em áreas ocupadas com vegetação natural em regeneração e em pastagem. As amostras de solo foram coletadas na profundidade de 0,0-0,2 m em uma grade amostral com 64 pontos, espaçados 10 m. Os dados foram submetidos à análise descritiva e, em seguida, foi realizada a análise geoestatística. Observaram-se os maiores valores para ADA e os menores valores de GF na área de pastagem. Todos os atributos apresentam dependência espacial para as duas áreas em estudo, com ajuste dos modelos esférico e exponencial. A confecção dos mapas temáticos por meio da krigagem ordinária permitiu melhor visualização da distribuição espacial dos atributos de solo.

Interactions between genes and alcohol on aggressive behavior and anger related traits : the oxytocin receptor gene as a candidate

Alkoholberusning är en av de starkaste riskfaktorerna för aggressivt beteende. Alla individer blir dock inte aggressiva under alkoholberusning. I sin doktorsavhandling undersökte Johansson ifall individens genetiska uppsättning kan förklara skillnader i vem som reagerar på alkohol med ökat aggressivt beteende och ilska och vem som inte gör det. Resultaten visade att individer som är bärare av en viss variant av genen som kodar för oxytocinets receptorer är i högre grad benägna att uppvisa aggressivt beteende än andra när de är alkoholberusade. Sambandet mellan alkohol och ilska påverkades även av individens genetiska uppsättning av två oxytocinreceptorgenvarianter, vilket antyder att dessa genvarianter även påverkar benägenheten att känna ilska under alkoholberusning. Oxytocinet, som fungerar både som ett hormon och en neurotransmittor, har i tidigare studier visats ha breda effekter på sociala förmågor hos människan, såsom förmåga till igenkännande av andras känslouttryck. Resultaten är de första att hos människan experimentellt påvisa att vissa individer beter sig mer aggressivt än andra när de är berusade, beroende på individens genetiska uppsättning. ”Det är viktigt att komma ihåg att genens effekt i det här fallet inte är av en sådan natur att den direkt och ofrånkomligen orsakar aggressivt beteende. Med andra ord är det orimligt i detta fall att tänka att en individ skulle tillmätas ansvarsfrihet i exempelvis ett våldsbrottmål om hon bär på en viss variant av denna gen”, påpekar Johansson. Oxytocinreceptorgenens effekter analyserades i två olika urval. I ett experimentellt upplägg indelades 116 män slumpässigt i två grupper: en grupp som tilldelades alkoholhaltiga drycker, och en kontrollgrupp som tilldelades alkoholfria drycker. Aggressivt beteende mättes med ett laboratorietest där försökspersonerna fick bestraffa en fiktiv motspelare genom att spela upp motbjudande ljud för denne. Resultaten replikerades i ett populationsbaserat urval av män och kvinnor (n = 3755) vilka besvarat frågor om deras aggressiva beteenden, ilska, och alkoholanvändning.
