BODY WEIGHT AS A DETERMINANT OF CLINICAL EVOLUTION IN HAMSTERS (Mesocricetus auratus) INFECTED WITH Leishmania (Viannia) panamensis

SUMMARY The clinical outcome of infection with Leishmania species of the subgenus Viannia in hamster model (Mesocricetus auratus) has shown to be different depending on experimental protocol. Body weight has been a relevant determinant of the clinical outcome of the infection in hamsters with visceral leishmaniasis but its importance as a clinical parameter in hamsters with cutaneous leishmaniasis is not known. In this study, the clinical evolution of infection with L. (V) panamensis was evaluated in juvenile and adult male hamsters during 11 weeks by comparing clinical parameters such as attitude, temperature, respiratory rate, appearance of the stool, and body weight between infected and non-infected groups. Results showed that body weight decreased in adult hamsters after infection by L. (V) panamensis; this observation supports the use of body weight as an additional parameter to define the management or treatment of cutaneous leishmaniasis in infected adult hamsters used as an animal experimental model for leishmaniasis.

DENGUE DURING PREGNANCY: ASSOCIATION WITH LOW BIRTH WEIGHT AND PREMATURITY

The aim of this study was to evaluate the effects of dengue virus infection during pregnancy and its correlation with low birth weight, prematurity, and asphyxia. A non-concurrent cohort study reveals the association of dengue during pregnancy with prematurity and low birth weight, when birth occurred during the maternal-fetal viremia period (p = 0.016 and p < 0.0001, respectively).

An attempt to control schistosomiasis mansoni in an endemic area by the use of Hycanthone as chemotherapeutic agent

Hycanthone in a single dose of 3.3 mg/kg of body weight was used to treal mansoni schistosomiasis in 597 persons (83%) of the population of the endemic vilage of Canabrava. Ninety two patients received a 2nd course 14 months later. There was one death em the 2nd treatment. The cure rate after one stool examination was smaller after the 2ni treatment in comparison with the first one. Re-infections did not occur imediately after the treatment. Three years later the prevalence of persons passing eggs through one stool examination was 19% compared to the 46.3% before the treatment. Adults are more resistant to the re-infections than younger.

The Effect of Long-Chain Polyunsaturated Fatty Acids Intake During Pregnancy on Adiposity of Healthy Full-Term Offspring at Birth

OBJECTIVE: The adjusted effect of long-chain polyunsaturated fatty acid (LCPUFA) intake during pregnancy on adiposity at birth of healthy full-term appropriate-for-gestational age neonates was evaluated. STUDY DESIGN: In a cross-sectional convenience sample of 100 mother and infant dyads, LCPUFA intake during pregnancy was assessed by food frequency questionnaire with nutrient intake calculated using Food Processor Plus. Linear regression models for neonatal body composition measurements, assessed by air displacement plethysmography and anthropometry, were adjusted for maternal LCPUFA intakes, energy and macronutrient intakes, prepregnancy body mass index and gestational weight gain. RESULT: Positive associations between maternal docosahexaenoic acid intake and ponderal index in male offspring (β=0.165; 95% confidence interval (CI): 0.031-0.299; P=0.017), and between n-6:n-3 LCPUFA ratio intake and fat mass (β=0.021; 95% CI: 0.002-0.041; P=0.034) and percentage of fat mass (β=0.636; 95% CI: 0.125-1.147; P=0.016) in female offspring were found. CONCLUSION: Using a reliable validated method to assess body composition, adjusted positive associations between maternal docosahexaenoic acid intake and birth size in male offspring and between n-6:n-3 LCPUFA ratio intake and adiposity in female offspring were found, suggesting that maternal LCPUFA intake strongly influences fetal body composition.

Trypanosoma (herpetosoma) Rangeli tejera, 1920: influence of host weight, size of inoculum, and route of infection upon experimental parasitemia

To study the influence of host age, inoculum size, and route of infection on Trypanosoma (Herpetosoma) rangeli, 12 lots of 6.0 g albino mice (NMRI strain) were infected up. with from 25x10¹ to 25x10(6) trypomastigotes/gram body weight harvested from LIT medium. The lower inocula produced low but persistent parasitemias, while the higher inocula produced high levels of parasitemia that fell quickly, suggesting the mobilization of resistance mechanisms. In other experiments, i.p. inoculation produced higher parasitemias than s.c. inoculation, and 6.0 g mice had higher parasitemias than 16.0 or 26.0 g mice. Thus, a standard methodology would seem to be necessary in the study of the various strains and/or species that may make up the T. rangeli complex.

Re-evaluation of the basic procedures involved in the storage of measles vaccine in public health units of the municipality of Niterói, state of Rio de Janeiro, Brazil

Four years after the first visit seventeen public health units were visited again and evaluated as to standards of storage recommended by the Brazilian Immunization Programme. In 100% of the units, refrigerators and proper inside location of vaccines in the refrigerator were adequatety or regularfy maintained and checked, respectively. However, when control of temperature was checked, onfy 64.7% presented adequate storage conditions. In 94.1 % of the units, health workers complained of lack of immediate technical support in emergency situations. In 55.2 % the titers vaccine samples of were under the minimal recommended potency. It is necessary that the factors concerning the cold chain be continualfy evaluated so that the quality of the vaccines that will be used is not affected.

Análise do impacto na despesa pública com medicamentos decorrente da alteração do sistema de preços de referência

RESUMO - Com o presente trabalho pretende-se analisar o impacto na despesa pública com medicamentos decorrente da implementação do Decreto-Lei 48-A/2010, de 13 de Maio, e do Decreto-Lei 106-A/2010, de 1 de Outubro, nos anos de 2011 e 2012. Os referidos diplomas alteraram as regras de formação do preço de referência e terão contribuído para a redução da despesa do SNS com medicamentos verificada em 2011 e 2012. Crê-se que antes da implementação dos referidos diplomas, o mercado concorrencial de medicamentos genéricos não apresentava a competição necessária, não se verificando a aproximação dos preços praticados ao seu custo marginal, de acordo com o previsto na teoria económica clássica. Pretende-se identificar o mercado total dos grupos homogéneos e analisar 50% do seu valor, através da identificação do preço de referência efectivo do 1º trimestre de 2011 ao 4º trimestre de 2012 e do cálculo do preço de referência expectável, na ausência da implementação dos referidos diplomas, com base nas regras existentes antes da implementação dos referidos diplomas. A identificação o peso relativo da alteração das regras do sistema de preços de referência, na despesa do SNS com medicamentos ocorrida em 2011 e 2012, poderemos delinear com maior rigor futuras estratégicas de controlo da despesa pública com medicamentos. Um factor de especial relevância dado o contexto actual de austeridade.

Hipertensão arterial em adolescentes escolarizados da área de intervenção do Centro de Saúde de Queluz

RESUMO - A hipertensão arterial é uma das maiores causas de mortalidade e morbilidade mundial, sendo responsável por cerca de 7,1 milhões de mortes anualmente. A tensão arterial elevada no início da vida está associado a hipertensão na idade adulta, sendo a adolescência uma altura fundamental para modificar estilos de vida e comportamentos que possam diminuir a prevalência de hipertensão. Os dados existentes sobre a hipertensão arterial na adolescência em Portugal não são consistentes, mas parecem apontar para um aumento da prevalência. Entre Janeiro e Março de 2007 foi realizado um estudo descritivo e transversal, para determinar a prevalência de hipertensão dos alunos do 7º Ano das Escolas da área de intervenção do Centro de Saúde de Queluz. Foram avaliados sexo, idade, tensão arterial, perfil estato-ponderal, antecedentes familiares de hipertensão arterial e prática de exercício físico de 902 alunos. O estudo determinou uma taxa de prevalência de hipertensão arterial global de 25,3%, mais prevalente no sexo feminino (30,3%) do que no masculino (19,6%). Nos indivíduos com IMC superior a 25 kg/m2, foi encontrada uma prevalência de 50% de hipertensão sendo de apenas 21,2% nos com um perfil estato-poderal mais baixo. O Odds Ratio ajustado para raça, sexo, idade e turno (manhã/tarde) foi de 2,33 para indivíduos com um IMC superior a 25 kg/m2. Estes dados revelam a necessidade da implementação de medidas de prevenção da doença e promoção da saúde, tendo como objectivo a diminuição da prevalência deste factor de risco e das doenças que lhe estão associadas.

Portuguese average cost of capital

The oldest Portuguese share index still being calculated is the BVL/PSI-General, one which started the daily series on 5/Jan/1988 with a base value of 1000 points. Everyday a single value is computed based on the closing prices of all the shares included in the sample. Also, all corporate events affecting the price of any share beyond market sentiment are taken into account through proper adjustments, either in the numerator or the denominator of the formula. However, for dates before January 1988, there is nothing comparable to this index since the two different series known either never disclosed the methodology adopted to calculate the index or followed solutions not compatible with the above index. The present paper explains the solutions adopted to replicate as closely as possible the methodology of the BVL-General index to the main market of the Lisbon Exchange for the period 1978 – 1987. This is the first estimate of the historical Equity Risk Premium in Portugal above short-term risk-free rate from the re-opening of the market following the Carnation Revolution (and the accompanying nationalizations), to the present. In showing a value of the same order of magnitude found in other countries, the paper invites further studies on the effects of political decisions such as privatizations and joining the European Union.
