Mortes maternas: revisão do fator de correção para os dados oficiais

O objetivo foi comparar as mortes maternas existentes no Sistema de Informações sobre Mortalidade (SIM/MS) com as do "Estudo da mortalidade de mulheres em idade fértil" e estimar novos fatores de correção. Analisaram-se 7.332 declarações de óbito feminino (DO) de dez a 49 anos, de residentes nas capitais brasileiras, no 1o semestre de 2002. Realizou-se pareamento dos conjuntos de DO (as originalmente preenchidas pelos médicos e aquelas obtidas com o resgate de dados) com as DO do SIM/MS. A subenumeração das mortes por causas maternas, no SIM/MS, foi de 21,4 por cento e, das mortes maternas, 16 por cento . Os novos fatores de ajuste para as mortes maternas nas regiões brasileiras foram: 0,93 (Norte), 1,17 (Nordeste), 1,28 (Sudeste), 1,10 (Sul) e 1,47 (Centro-oeste); para o pa's, foi igual a 1,19. Os Comitês de Morte Materna investigam os óbitos femininos em idade fértil, mas, ainda, restam imprecisões que podem inviabilizar condutas preventivas eficientes

Television and narratives: cultural identities in globalization age

This paper describes a current research integrated in an international and interdisciplinary project and developed in a global environment between two different tendencies: integration and desintegration. In this scenary, television narrative arises as an essential tool to create and consolidate new cultural identities in order to get a popular narrative on the concept of nation.

A Paradigm Shift in Predoctoral Dental Curricula in Brazil: Evaluating the Process of Change

In 2002, the Brazilian Ministry of Education approved the official curricular guidelines for undergraduate courses in Brazil to be adopted by the nation's 188 dental schools. In 2005-06, the Brazilian Dental Education Association (BDEA) promoted workshops in forty-eight of the schools to verify the degree of transformation of the curriculum based on these guidelines. Among the areas analyzed were course philosophy (variables were v1: knowledge production based on the needs of the Brazilian Public Health System [BPHS]; v2: health determinants; and v3: postgraduate studies and permanent education); pedagogical skills (v4: curricular structure; v5: changes in pedagogic and didactic skills; and v6: course program orientation); and dental practice scenarios (v7: diversity of the scenarios for training/learning; v8: academic health care centers opened to the BPHS; and v9: participation of students in health care delivery for the population). The subjects consisted of faculty members (n=711), students (n=228), and employees (n=14). The results showed an incipient degree of curriculum transformation. The degree of innovation was statistically different depending on the type of university (public or private) for variables I, 2, 4, 5, 6, and 7. Private schools reported a higher level of innovation than public institutions. Resistance to transforming the dental curriculum according to the official guidelines may be linked to an ideological conception that supports the private practice model, continues to have faculty members direct all classroom activities, and prevents students from developing an understanding of professional practice as targeted towards the oral health needs of all segments of society.

Confederações indígenas em luta por participação política, comercial e territorial: Argentina, 1852 - 1859

Entre 1852 e 1859, a atual Argentina se encontrava politicamente dividida entre Buenos Aires e a Confederação, que congregava as demais Províncias. Nesse período, diferentes grupos étnicos dos pampas, dos Andes e da Patagônia se organizaram em confederações indígenas com o objetivo de enfrentar os avanços territoriais, defender suas autonomias e a participação em lucrativas redes de comércio. Nesta luta por autonomia política, territorial e comercial, negociaram com os grupos criollos em luta pelo poder, avaliaram seus projetos e aderiram a aquele que os reconheceu enquanto interlocutores políticos e aliados militares. Participantes ativos da política argentina, conseguiram reconquistar territórios e oferecer intensas resistências aos criollos.

Modern Society and Culture in Brazil The Sociology of Florestan Fernandes

The establishment of modern sociology in Brazil was part of a thoroughgoing modernization of the country that began in the 1930s and the years immediately following World War II. The founding of the University of Sao Paulo made possible the systematic training of scientists devoted to teaching and research and broadened the way learning was understood. Florestan Fernandes was the outstanding personality among the first social scientists that the university produced, and the picture of the Brazilian sociologist today is largely inspired by his career. Enthusiasm and scientific rigor were the hallmarks of his approach. His early work reflects intellectuals` shared belief in the power of ideas to regenerate the nation, freeing it from a past that they condemned. The mature reflection of his later works retreats from this optimistic view, recognizing the emergence of modern society in Brazil as a complex process with mixed results.

ACHIEVEMENTS AND CHALLENGES OF ISPRM

This paper describes the history of the International Society of Physical and Rehabilitation Medicine (ISPRM) Past achievements. and current challenges are outlined ISPRM has been successful In setting up a central office. attracting individual and national members,. holding International congresses, and establishing relations with the Journal of Rehabilitation Medicine (JRM) as the organization`s official journal ISPRM is currently; In official relations with the World Health Organization (WHO) and collaborates closely, with WHO`s Disability and Rehabilitation team ISPRM, however also faces challenges with regard to its growth and the realization of its goals These Include boundaries of voluntary leadership. limited economic resources, the need for enhancing the central office. variations in membership. limits of the current congress bidding system and structure, relations with regional societies, and the need to further develop policies within the field of Physical and Rehabilitation Medicine (PRM) and In relation to WHO and the United Nations system is concluded that ISPRM must evolve from an organization, of which the main activities ay-e to hold a biennial congress hosted by a member nation and to provide input to WHO on request. Into a professional non-governmental organization (NGO) ISPRA should embark on assuming, a leadership role at the further development of PRM within the broader area of human functioning and rehabilitation

Myocardial Perfusion Imaging Is a Strong Predictor of Death in Women

OBJECTIVES We sought to assess the prognostic value and risk classification improvement using contemporary single-photon emission computed tomography myocardial perfusion imaging (SPECT-MPI) to predict all-cause mortality. BACKGROUND Myocardial perfusion is a strong estimator of prognosis. Evidence published to date has not established the added prognostic value of SPECT-MPI nor defined an approach to detect improve classification of risk in women from a developing nation. METHODS A total of 2,225 women referred for SPECT-MPI were followed by a mean period of 3.7 +/- 1.4 years. SPECT-MPI results were classified as abnormal on the presence of any perfusion defect. Abnormal scans were further classified as with mild/moderate reversible, severe reversible, partial reversible, or fixed perfusion defects. Risk estimates for incident mortality were categorized as <1%/year, 1% to 2%/year, and >2%/year using Cox proportional hazard models. Risk-adjusted models incorporated clinical risk factors, left ventricular ejection fraction (LVEF), and perfusion variables. RESULTS All-cause death occurred in 139 patients. SPECT-MPI significantly risk stratified the population; patients with abnormal scans had significantly higher death rates compared with patients with normal scans, 13.1% versus 4.0%, respectively (p < 0.001). Cox analysis demonstrated that after adjusting for clinical risk factors and LVEF, SPECT-MPI improved the model discrimination (integrated discrimination index = 0.009; p = 0.02), added significant incremental prognostic information (global chi-square increased from 87.7 to 127.1; p < 0.0001), and improved risk prediction (net reclassification improvement = 0.12; p = 0.005). CONCLUSIONS SPECT-MPI added significant incremental prognostic information to clinical and left ventricular functional variables while enhancing the ability to classify this Brazilian female population into low-and high-risk categories of all-cause mortality.

NOVEL 65 kDa RNA-BINDING PROTEIN IN SQUID PRESYNAPTIC TERMINALS

A polyclonal antibody (C4), raised against the head domain of chicken myosin Va, reacted strongly towards a 65 kDa polypeptide (p65) on Western blots of extracts from squid optic lobes but did not recognize the heavy chain of squid myosin V. This peptide was not recognized by other myosin Va antibodies, nor by an antibody specific for squid myosin V. In an attempt to identify it, p65 was purified from optic lobes of Loligo plei by cationic exchange and reverse phase chromatography. Several peptide sequences were obtained by mass spectroscopy from p65 cut from sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) gels. BLAST analysis and partial matching with expressed sequence tags (ESTs) from a Loligo pealei data bank indicated that p65 contains consensus signatures for the heterogeneous nuclear ribonucleoprotein (hnRNP) A/B family of RNA-binding proteins. Centrifugation of post mitochondrial extracts from optic lobes on sucrose gradients after treatment with RNase gave biochemical evidence that p65 associates with cytoplasmic RNP complexes in an RNA-dependent manner. Immunohistochemistry and immunofluorescence studies using the C4 antibody showed partial co-labeling with an antibody against squid synaptotagmin in bands within the outer plexiform layer of the optic lobes and at the presynaptic zone of the stellate ganglion. Also, punctate labeling by the C4 antibody was observed within isolated optic lobe synaptosomes. The data indicate that p65 is a novel RNA-binding protein located to the presynaptic terminal within squid neurons and may have a role in synaptic localization of RNA and its translation or processing.

Effects of creatine supplementation on homocysteine levels and lipid peroxidation in rats

Hyperhomocysteinaemia is an independent risk factor for CVD. Recent data show a relationship between homocysteine (Hcy) and free radical formation. Since creatine synthesis is responsible for most of the methyl group transfers that result in Hcy formation, creatine supplementation might inhibit Hcy production and reduce free radical formation. The present study investigated the effects of creatine supplementation on Hcy levels and lipid peroxidation biomarkers. Thirty rats were divided into three groups: control group; diet with creatine group (DCr; 2% creatine in the diet for 28 d); creatine overload plus diet with creatine group (CrO + D; 5 g creatine/kg by oral administration for 5 d + 2 % in the diet for 23 d). Plasma Hcy was significantly lower (P<0.05) in DCr (7.5 (SD 1.2) mu mol/l) and CrO + D (7.2 (SD 1.7) mu mol/l) groups compared with the control group (12.4 (SD 2.2) mu mol/l). Both plasma thiobarbituric acid-reactive species (TBARS) (control, 10 (SD 3.4); DCr, 4.9 (So 0.7); CrO + D, 2.4 (SD 1) mu mol/l) and plasma total glutathione (control, 4.3 (SD 1.9); DCr, 2.5 (SD 0.8); CrO + D, 1.8 (SD 0.5) mu mol/l) were lower in the groups that received creatine (P<0.05). In addition, Hcy showed significant negative correlation (P<0.05) with plasma creatine (r - 0.61) and positive correlation with plasma TBARS (r 0.74). Plasma creatine was negatively correlated with plasma TBARS (r - 0.75) and total peroxide (r - 0.40). We conclude that creatine supplementation reduces plasma Hcy levels and lipid peroxidation biomarkers, suggesting a protective role against oxidative damage. Modulating Hcy fort-nation may, however, influence glutathione synthesis and thereby affect the redox state of the cells.

Audiology in Brazil

The profession of audiology took root in Brazil nearly a half a century ago and has since blossomed into a flourishing, well-developed field. Currently, audiologists in Brazil work at private institutions, including private medical practices and dedicated speech and hearing clinics. They are also employed in a wide array of public institutions, including community clinics, elementary schools, colleges, and universities. In both the private sector and health clinics, audiologists perform diagnostic evaluations of auditory and vestibular disorders, select and fit hearing aids, and provide aural rehabilitation. At the public level, they assist with workers` health programs, dispense hearing aids, and aural rehabilitation. There is always room to grow, however, and the future of audiology in Brazil holds both challenges and opportunity. The following article will sketch the development of audiology training and practice in Brazil, provide a picture of how the field stands today, and summarize the unique challenges which the profession faces in this large and diverse nation.
