Immunoglobulin E-rheumatoid factor in juvenile rheumatoid arthritis

OBJECTIVES: To determine the presence of immunoglobulin E-rheumatoid factor in patients with juvenile rheumatoid arthritis and to correlate it with clinical and laboratory parameters. METHODS: A multicenter prospective study was carried out from January 1993 to January 1999 with the enrollment of 3 centers of pediatric rheumatology. Ninety-one children with juvenile rheumatoid arthritis diagnosed according to the American College of Rheumatology criteria were studied: 38 (42%) with systemic, 28 (31%) with pauciarticular, and 25 (27%) with polyarticular onset. Ages ranged from 2.1 years to 22.6 years (mean 10.5 ± 4.7), with 59 (65%) girls. The control group consisted of 45 healthy children. The detection of immunoglobulin E-rheumatoid factor was carried out utilizing an enzyme-linked immunosorbent assay. Associations of immunoglobulin E-rheumatoid factor with immunoglobulin M-rheumatoid factor (latex agglutination test), total serum immunoglobulin E, erythrocyte sedimentation rate, antinuclear antibody, and functional and radiological classes III or IV were analyzed. RESULTS: Positive immunoglobulin E-rheumatoid factor was found in 15 (16.5%) of the 91 children with juvenile rheumatoid arthritis: 7 (18.5%) with systemic, 5 (18%) with pauciarticular, and 3 (12%) with polyarticular onset. A significant correlation was observed between immunoglobulin E-rheumatoid factor and total serum immunoglobulin E in the juvenile rheumatoid arthritis patients. No correlation was found between immunoglobulin E-rheumatoid factor and positive latex agglutination slide test, erythrocyte sedimentation rate, antinuclear antibody, or the functional and radiological classes III or IV in any disease onset group. In 4 out of 45 control children (8.9%), immunoglobulin E-rheumatoid factor was positive but with no correlation with total serum immunoglobulin E levels. CONCLUSIONS: Immunoglobulin E-rheumatoid factor could be detected in 16.5% of juvenile rheumatoid arthritis patients, particularly in those with high levels of total serum immunoglobulin E, and immunoglobulin E-rheumatoid factor appears not to be associated with disease activity or severity.

Adrenocortical tumors: results of treatment and study of Weiss's score as a prognostic factor

PURPOSE: The differential diagnosis between benign and malignant adrenal cortical tumors circumscribed to the gland is controversial. One hundred and seven patients with adrenal cortex tumors (excluding those with primary hyperaldosteronism) were studied to assess the 5-year survival rate of adults, children, patients stratified by pathological stage, and patients stratified according to Weiss's score of <3 or >3. METHODS: The patients were evaluated both clinically and biochemically. One hundred and five patients underwent surgery and were classified pathologically as stages I, II, III, or IV. The tumors were weighed, measured, and classified according to Weiss's criteria and divided into 2 groups: <3 and >3. RESULTS: After 5 years, the survival rate was 77.5% for the whole group, 74.61% for the adults, 84.3% for the children, 100% for stage I, 83.9% for stage II, 33% for stage III, and 11.7% for stage IV groups. Additionally, after 5 years, 100% of the patients with tumors with Weiss's score <3 were alive compared to 61.65% of those with Weiss's score >3. The average weights of the tumors of score <3 and >3 were 23.38 g ± 41.36 g and 376.3 ± 538.76 g, respectively, which is a statistically significant difference. The average sizes of tumors of Weiss's score <3 and >3 were 3.67 ± 2.2 cm and 9.64 ± 5.8 cm, respectively, which is also a statistically significant difference. CONCLUSIONS: Weiss's score may be a good prognostic factor for tumors of the adrenal cortex. Additionally, there was a statistically significant difference between the average weight and size of tumors with benign behavior (Weiss's score <3) and those with malignant behavior (Weiss's score >3).

Microstructural changes befor macroeconomic announcements: Predictability of economic surprises in the U.S. market

Flow of new information is what produces price changes, understanding if the market is unbalanced is fundamental to know how much inventory market makers should keep during an important economic release. After identifying which economic indicators impact the S&P and 10 year Treasuries. The Volume Synchronized Probability of Information-Based Trading (VPIN) will be used as a predictability measure. The results point to some predictability power over economic surprises of the VPIN metric, mainly when calculated using the S&P. This finding appears to be supported when analysing depth imbalance before economic releases. Inferior results were achieved when using treasuries. The final aim of this study is to fill the gap between microstructural changes and macroeconomic events.

Custos indirectos associados à obesidade em Portugal

RESUMO - A obesidade constitui um importante problema de saúde pública com consequências económicas de grande dimensão. Os obesos têm um risco acrescido de contrair doenças e de sofrer morte prematura devido a problemas como a diabetes, hipertensão arterial, AVC, insuficiência cardíaca e algumas neoplasias malignas. O presente estudo tem como objectivo estimar o custo económico indirecto (valor da produção perdida) associado à obesidade em Portugal no ano de 2002. O estudo adopta uma abordagem tipo custos da doença baseada na prevalência. Os dados são retirados do Inquérito Nacional de Saúde e estatísticas de rotina publicadas pelo INE e por outros organismos oficiais. Consideram-se como obesas pessoas com índice de massa corporal (IMC) ≥ 30 kg/m2 e estabelecem-se como limites etários para participação em actividades económicas produtivas as idades compreendidas entre os 15 e os 64 anos. A estratégia de imputação de custos ao factor de risco obesidade caracteriza- se por estimar, para a população portuguesa, as proporções de doença e morte prematura atribuíveis à obesidade e em multiplicar as estimativas populacionais encontradas pelo valor da produtividade económica potencial das pessoas afectadas. O custo indirecto total da obesidade em Portugal no ano de 2002 foi estimado em 199,8 milhões de euros. A mortalidade contribuiu com 58,4% deste valor (117 milhões de euros) e a morbilidade com 41,6% (83 milhões de euros). Os custos da morbilidade advêm de mais de 1,6 milhões de dias de incapacidade anuais, principalmente por faltas ao trabalho associadas a doenças do sistema circulatório e diabetes tipo II. Os custos da mortalidade são o resultado de 18 733 potenciais anos de vida activa perdidos, numa razão de 3 mortes masculinas por cada morte feminina. Os resultados indicam que a obesidade acarreta consideráveis perdas económicas para o país. Comparando os resultados com um estudo complementar que calculou os custos directos (em cuidados de saúde) da obesidade, verifica-se que a componente indirecta representa 40,2% do total dos custos da obesidade. A implementação de estratégias que prevenissem ou reduzissem a incidência e prevalência de obesidade em Portugal poderia gerar ganhos de produtividade elevados. Para conhecer a dimensão destes ganhos é necessária mais investigação sobre os benefícios clínicos e relação custo-efectividade de estratégias para a redução da obesidade.

Entre o fazer e o dever

A compreensão da ocorrência das doenças em termos de risco e o estabelecimento de relações com os chamados estilos de vida, colocam na experiência de doença um acréscimo de conotações morais, um dever de autodisciplina e responsabilidade. Estes princípios têm sido inúmeras vezes sublinhados nos discursos e políticas da Saúde Pública, nomeadamente no que concerne às doenças cardiovasculares pela importância epidemiológica, económica e social de que se revestem e consequente necessidade de redução da sua grande incidência na população, como é o caso de Portugal. A hipertensão, como doença crónica e fator de risco cardiovascular sujeita os doentes a controlo médico periódico, terapêutica farmacológica e impele a um comprometimento com comportamentos alimentares e exercício físico adequado. Através das entrevistas realizadas a doentes hipertensos utentes da consulta específica em Cuidados de Saúde Primários, verifica-se a presença de modos diversos de agir perante a circunstância de se ter hipertensão arterial, mostrando a presença de várias racionalidades, apreciações e valorações práticas dos comportamentos de saúde e doença e do próprio corpo. Para os doentes hipertensos entrevistados, a hipertensão arterial não é encarada como uma “verdadeira doença”, sendo vista sobretudo como resultado do envelhecimento e dos excessos que se acumularam no corpo, consequentes da própria vida. Nas narrativas de experiência de doença, os conceitos de moderação e equilíbrio, “ter cuidado”, parecem servir de mecanismo de operacionalização entre aquilo que são as recomendações médicas e as práticas individuais. Constatam-se as capacidades dos doentes hipertensos construírem para si formas de gestão da doença e do medo, sendo que os seus comportamentos podem passar por assumir o controlo dos fatores de risco ou ignorá-los. Em qualquer dos casos, as representações e ações relativas à hipertensão e às recomendações médicas a ela associadas integram-se nas práticas quotidianas dos doentes, ajustando-se a hábitos e representações instaladas, constituindo-se em modos distintos de agir dos doentes hipertensos.

The economic assessment of health benefits of active transport

Purpose:This chapter addresses the economic assessment of health benefits of active transport and presents most recent valuation studies with an overview of progresses made towards the inclusion of health benefits in the cost-benefit analysis (CBA) of active transport. Methodology/approach: It is built upon the contracted study for the World Health Organization (WHO) on the economic appraisal of health benefits of walking and cycling investments at the city of Viana do Castelo, the former pilot study in Portugal for evaluating the health benefits of non-motorized transport using the WHO Health Economic Assessment Tool (HEAT). The relative risk values adopted in the HEAT for walking refer to adult population of the age group 20â 74 years and the assessment focus in on average physical activity/regular behaviour of groups of pedestrians and all-cause mortality health impacts. During the case study, it was developed and implemented a mobility survey which aimed to collect behavioural data before and after a street intervention in the historic centre. Findings: Most recent appraisal guidance of walking and cycling and health impact modelling studies reviewed confirm that further research is expected before a more comprehensive appraisal procedure can be adopted in Europe, able to integrate physical activity effects along with other health risks such as those related to road traffic injuries and exposure to air pollution. Social implications: The health benefits assessment of walking investments helped local decision-makers to progress towards sustainable mobility options in the city. Making the population aware of the potential health benefits of regular walking can encourage more people to uptake active transport as part of their daily activities. Originality/value: This study provides a useful review of the health benefits of active transport with a comprehensive analysis of valuation studies, presenting value-added information. It then reports a former assessment of the health effects of active transport in the Portuguese context (case study) using the state-of-the-art economic analysis tool (HEAT) of the World Health Organization which is believed to contribute to a paradigm shift in the transport policy and appraisal practice given the need of shaping future cities (and their citizens) for health through more investments in active transport.

Economic evaluation of occupational safety preventive measures in a hospital

BACKGROUND: When an organization performs an integrated analysis of risks through its Occupational Health and Safety Management System, several steps are suggested to address the implications of the identified risks. Namely, the organization should make a detailed analysis of the monetary impact for the organization of each of the preventive measures considered. However, it is also important to perform an analysis of the impact of each measure on society (externalities). OBJECTIVE: The aim of this paper is to present a case study related to the application of the proposed economic evaluation methodology. METHODS: An analysis of the work accidents in a hospital has been made. Three of the major types of accidents have been selected: needle stings, falls and excessive strain. Following the risk assessment, some preventive measures have been designed. Subsequently, the Benefit/Cost ratio (B/C) of these measures has been calculated, both in financial terms (from the organization’s perspective) and in economic terms (including the benefits for the worker and for the Society). RESULTS: While the financial ratio is only advantageous in some cases, when the externalities are taken into account, the B/C ratio increases significantly. CONCLUSIONS: It is important to consider external
