RESUMO: Introdu����o e objetivos: N��o existia um estudo multic��ntrico que descrevesse as caracter��sticas dos doentes com EM, da doen��a em si, ou do seu tratamento, em Portugal.M��todos: Doentes McDonald 2010 positivos foram sequencialmente recrutados em 7 centros entre Maio e Novembro 2014. Aplicou-se um Caderno de Recolha de Dados incidindo na demografia, doen��a, educa����o e emprego (estudo PORT-MS). Resultados: 561 doentes inclu��dos. Primeiros sintomas aos 30,2��10,5 anos (RRMS 29,2��10, PPMS 39,4��11,7, p<0,001); diagn��stico 3,2��5,3 anos depois (RRMS 3,0��5,1, PPMS 4,9��2,5, p=0,002); tempo de doen��a ap��s diagn��stico 9,4��7,2 anos (semelhante RRMS no diagn��stico e PPMS); idade atual 42,9��12,4 anos (grupo RRMS no diagn��stico 42,0��12,1, PPMS 52,5��11,3, p<0,001); EDSS atual 2,5 (RRMS 2.0, PPMS 6.0); propor����o feminino:masculino �� 2,5:1 (RRMS semelhante, PPMS 1,1:1, p<0,05); no diagn��stico RRMS 90,6%, SPMS 0,9%, PPMS 8,6%; 9,5% dos RRMS encontravam-se em SP na inclusão (nomeadamente os com mais idade no diagn��stico e/ou atualidade ou tempo de doen��a mais prolongado). PPMS mais frequente em doentes diagnosticados mais tardiamente (p<0,001), onde aumenta tamb��m ligeiramente a propor����o de mulheres na PPMS. Nas ��ltimas d��cadas: novos casos mostram estabilidade na propor����o de g��neros e tipos de doen��a; idade nos primeiros sintomas e no diagn��stico aumentou ligeiramente, tempo entre eles diminuiu ligeiramente. Propor����o sob DMT (Maio 2014): global 84,5%; atualmente RRMS 90,4%; SPMS 70,8%; PPMS 36,8%; progressivas agregadas 48%. Tipo de DMT, amostra global: interfer��es 56,5%, GA 18,4%, Natalizumab 11,6%, Fingolimod 9,7%. Global: economicamente ativos 61,5%, desemprego 13,5%, 74,1% dos n��o activos est��o reformados por doen��a. Gravidezes ap��s diagn��stico em 15% mulheres. Casos com hist��ria familiar positiva 7,8%. Discussão e conclus��es: Inclu��da cerca de 10% da popula����o portuguesa. Resultados congruentes com dados internacionais. Elevada propor����o sob DMT, mesmo EDSS alto e formas progressivas. Terap��uticas de segunda linha sub representadas. Doentes jovens e com doen��a ligeira com vida econ��mica ativa; restantes essencialmente reformados por doen��a.---------------- ABSTRACT : Background/aims: In Portugal, there wasn���t a multicentric study on the general characteristics (demography, disease milestones, DMT, socioeconomic status) of Multiple Sclerosis patients. Methods: Patients fulfilling McDonald 2010 criteria were sequentially recruited from May to November 2014 in 7 centers and data was systematically collected. Results: 561 patients included. First symptoms occurred at 30,2��10,5 years-old (RRMS 29,2��10, PPMS 39,4��11,7, p<0,001); diagnosis 3,2��5,3 years later (RRMS 3,0��5,1, PPMS 4,9��2,5, p=0,002); 9,4��7,2 years elapsed since diagnosis (similar for those is RRMS at diagnosis and PPMS); current age 42,9��12,4 years-old (group RRMS at diagnosis 42,0��12,1, PPMS 52,5��11,3, p<0,001); current EDSS 2,5 (RRMS 2.0, PPMS 6.0); females to males 2,5:1 (RRMS similar, PPMS 1,1:1, p<0,05); at diagnosis RRMS 90,6%, SPMS 0,9%, PPMS 8,6%; 9,5% of RRMS reached SP at inclusion (those older at diagnosis, in actuality, or with longer follow-up). PPMS more frequente in patients diagnosed at older ages (p<0,001), also slight increase in females. Along the last decades: new cases have showed stable proportions of gender and disease types; age at first symptoms and diagnosis slightly increased, time between them slightly decreased. Proportion on DMT (May 2014): 84,5% of all; 90,4% of currently in RRMS; 70,8% of SPMS; 36,8% of PPMS; 48% of progressive forms together. Type of DMT, all patients: interferons 56,5%, Glatiramer Acetate 18,4%, Natalizumab 11,6%, Fingolimod 9,7%. Economically active 61,5% of all, unemployment 13,5%, 74,1% of non-active are retired due to disease. Females pregnant after diagnosis 15%. Positive family cases in 7,8%. Discussion/Conclusions: 10% of the national MS population collected. Data generally consistente with international reports. Proportion under DMT relatively high in all disease types, but second line therapies underrepresented. Young patients with mild disease have an active economic life. Those not active are essentially retired due to disease.

Anatomy of the portuguese stock market risk and return in the 1977-2012 period

This paper analyses the Portuguese stock market since it reopened in 1977, with a special focus on the evolution of the statistic and stochastic characteristics of the market return throughout this 36 year period. The market return for the period of time between 1977 and 2012 (September 28th) is estimated and then compared with the return that would have been achieved with Government bonds and treasury bills, which allows us to confirm that the hierarchy of return / risk across the different financial instruments is verified. The market risk premium for this 36 year period is also estimated and a comparison with other markets is performed, suggesting that the Portuguese market���s risk has not been compensated by an adequate return. The study also examines the evolution of the Portuguese market���s volatility in the 1977-2012 period and compares it with other markets, showing the existence of extremely high peaks during the first 11 years, but indicating a downwards trend throughout the whole period under analysis. Finally, the correlation between market returns for Portugal and for other countries and the degree of integration are estimated and their evolution throughout time is assessed, leading to the conclusion that the performance of the Portuguese stock market has become increasingly correlated with major European markets ��� correlation with some markets close to 0.70 from 2000 onwards-, but that country-specific risk factors are still relevant.

Practices and trends of telework in the Portuguese industry: the results of surveys in the textile, metal and software sectors

The aim of the TeleRisk Project on labour relations and professional risks within the context of teleworking in Portugal ��� supported by IDICT ��� Institute for Development and Inspection of Working Conditions (Ministry of Labour), is to study the practices and forms of teleworking in the manufacturing sectors in Portugal. The project chose also the software industry as a reference sector, even though it does not intend to exclude from the study any other sector of activity or the so-called ���hybrid��� forms of work. However, the latter must have some of the characteristics of telework. The project thus takes into account the so-called ���traditional��� sectors of activity, namely textile and machinery and metal engineering (machinery and equipment), not usually associated to this type of work. However, telework could include, in the so-called ���traditional��� sectors, other variations that are not found in technologically based sectors. One of the evaluation methods for the dynamics associated to telework consisted in carrying out surveys by means of questionnaires, aimed at employers in the sectors analysed. This paper presents some of the results of those surveys. It is important to mention that, being a preliminary analysis, it means that it does not pretend to have exhausted all the issues in the survey, but has meant that it shows the bigger tendencies, in terms of teleworking practices, of the Portuguese industry.

Obama's law : analysis of a breakthrough law on healthcare access and lessons for the Portuguese health system management

ABSTRACT - The Patient Protection and Affordable Care Act shook the foundations of the US health system, offering all Americans access to health care by changing the way the health insurance industry works. As President Obama signed the Act on 23 March 2010, he said that it stood for ���the core principle that everybody should have some basic security when it comes to their health care���. Unlike the U.S., the Article 64 of the Portuguese Constitution provides, since 1976, the right to universal access to health care. However, facing a severe economic crisis, Portugal has, under the supervision of the Troika, a tight schedule to implement measures to improve the efficiency of the National Health Service. Both countries are therefore despite their different situation, in a conjuncture of reform and the use of new health management measures. The present work, using a qualitative research methodology examines the Affordable Care Act in order to describe its principles and enforcement mechanisms. In order to describe the reality in Portugal, the Portuguese health system and the measures imposed by Troika are also analyzed. The intention of this entire analysis is not only to disclose the innovative U.S. law, but to find some innovative measures that could serve health management in Portugal. Essentially we identified the Exchanges and Wellness Programs, described throughout this work, leaving also the idea of the possibility of using them in the Portuguese national health system.

Reallocation of resources between the tradable and non-tradable sector in Portugal: Assessing the degree of structural transformation in the Portuguese economy

Portugal implemented a large number of structural reforms in the recent years, which are expected to enhance the allocation of resources in the economy, namely from the non-tradable to tradable sector. We argue that the methodology to identify the tradable sector used by some international institutions is outdated and may hamper an accurate assessment of the progress achieved so far. Based on an enhanced methodology to identify the tradable sector, we are able to provide a more accurate, clearer picture of the recent structural developments of the Portuguese economy.
