RESUMEN
Objetivo: Analisar a tendência da mortalidade por paracoccidioidomicose (PCM) e caracterizar o perfil sociodemográfico no Brasil e suas regiões geográficas numa série temporal de 25 anos. Métodos: Trata-se de estudo ecológico de séries temporais. Considerou-se como participantes do estudo a população brasileira dividida em faixas etárias, que tiveram como causa básica do óbito a PCM. Para calcular a variação percentual anual (VPA) dos coeficientes, na análise de tendência, foi utilizada a regressão de Prais-Winsten. Os coeficientes de mortalidade foram calculados a nível nacional, segundo as regiões geográficas, sexo e faixa etária e proporcional para as demais variáveis. Resultados: De acordo com os resultados deste estudo, ocorreram 2.101 óbitos por PCM no Brasil. A tendência ao longo dos 25 anos evidenciou um comportamento estável nas regiões Norte e Nordeste. Já no Sul, Sudeste e Centro-Oeste houve uma tendêndia de queda. A mortalidade média no Brasil foi de 84,04/100 mil hab., VPA -3,29 (IC 95% -2,43; -4,14). Levando em consideração a análise dos aspectos sociodemográficos, houve um predomínio de escolaridade ignorada (764; 36%), raça/ cor da pele branca (1.109; 53%), estado civil misto: casado (942; 45%) e solteiro (640; 30%), local de ocorrência do óbito predominantemente no âmbito hospitalar (1.852; 88%). Conclusão: Tanto no Brasil como nas regiões geográficas Sudeste, Sul e Centro-Oeste a mortalidade por PCM apresentou-se com tendência temporal decrescente. Já nas regiões Nordeste e Norte a tendência foi estacionária. O perfil sociodemográfico dos pacientes que foram a óbito apontou para sexo masculino, adultos, de baixa escolaridade, brancos e casados.
Objective: To analyze the trend in mortality from paracoccidioidomycosis (PCM) and characterize the sociodemographic profile in Brazil and its geographic regions in a 25-year time series. Methods: This is an ecological time series study. The study participants were the Brazilian population divided into age groups whose underlying cause of death was PCM. To calculate the annual percentage change (VPA) of the coefficients in the trend analysis, the Prais-Winsten regression was used. National mortality coefficients were calculated according to geographic regions, sex and age group and proportional to the other variables. Results: According to this study, there were 2,101 deaths from PCM in Brazil. The trend over the 25 years showed stable behavior in the North and Northeast regions. In the South, Southeast, and Midwest, there was a downward trend. The average mortality in Brazil was 84.04/100,000 inhab., VPA -3.29 (95% CI -2.43; -4.14). According to the analysis of sociodemographic aspects, there was a predominance of ignored schooling (764 deaths; 36%), white race/skin color (1,109; 53%), mixed marital status: married (942; 45%) and single (640; 30%), and place of death predominantly in the hospital environment (1,852; 88%). Conclusion: In Brazil and in the Southeast, South, andMidwest geographic regions, mortality from PCM showed a decreasing temporal trend. In the Northeast and North regions, the trend was stationary. The sociodemographic profile of the dying patients indicated males, adults, with low education, white, and married.

RESUMEN
Atherosclerosis is a multifactorial inflammatory disease of blood vessels which decimates one in every three people in industrialized world. Despite the important newest clinical approaches, currently available strategies (e.g. nutritional, pharmacological and surgical) may only restrain the worsening of vascular disease. Since antiproliferative cyclopentenone prostaglandins (CP-PGs) are powerful anti-inflammatory agents, we developed a negatively charged liposome-based pharmaceutical formulation (LipoCardium) that specifically direct CP-PGs towards the injured arterial wall cells of atherosclerotic mice. In the blood stream, LipoCardium delivers its CP-PG contents only into activated arterial wall lining cells due to the presence of antibodies raised against vascular cell adhesion molecule-1 (VCAM-1), which is strongly expressed upon inflammation by endothelial cells and macrophage-foam cells as well. After 4 months in a high-lipid diet, all low-density lipoprotein receptor-deficient adult control mice died from myocardium infarction or stroke in less than 2 weeks, whereas LipoCardium-treated (2 weeks) animals (still under high-lipid diet) completely recovered from vascular injuries. In vitro studies using macrophage-foam cells suggested a tetravalent pattern for LipoCardium action: anti-inflammatory, antiproliferative (and pro-apoptotic only to foam cells), antilipogenic and cytoprotector (via heat-shock protein induction). These astonishing cellular effects were accompanied by a marked reduction in arterial wall thickness, neointimal hyperplasia and lipid accumulation, while guaranteed lifespan to be extended to the elderly age. Our findings suggest that LipoCardium may be safely tested in humans in a near future and may have conceptual implications in atherosclerosis therapy.

Disorders concerning the metabolism of plasma and intracellular lipids are hallmarks of atherosclerosis. However, failures in proper control of intracellular cholesterol balance, rather than simple cholesterol overloading due to augmented uptake, could fuel atherogenesis. Therefore, the understanding of atherosclerosis-associated lipid alterations, which feed an inflammatory microenvironment in the arterial wall, requires the meticulous investigation of several aspects of lipid synthesis, uptake and export from cells. In this regard, the presence of reactive cysteines in transcription factors and key enzymes of lipid metabolism may dictate cholesterol accumulation, and therefore the progression of vascular disease. The strong inhibitory effect of cysteine-reactant anti-inflammatory cyclopentenone prostaglandins (CP-PGs) over atherosclerosis progression in vivo (LipoCardium technology) symbolizes a new concept of atherosclerosis and its treatment. Results from this laboratory and those from other research groups have unraveled a novel facet in prostaglandin research in that CP-PGs may act as redox signals that guide lipid metabolism in atherosclerosis. By modifying enzymes (e.g., HMG-CoA reductase, ACAT and cholesteryl ester hydrolases) and transcription factors (e.g., NF-kappaB and Keap1) involved in inflammation and lipid metabolism, CP-PGs (especially those of A-series) induce pivotal changes in glutathione and lipid metabolism that completely arrest atherosclerosis progression. Hence, pharmacological manipulation of lipid metabolism by CP-PGs may be a novel and invaluable strategy for treating atherosclerosis. Also, a better understanding of why CP-PGs do not resolve inflammation physiologically may explain many unsolved questions and yield insights into atherogenesis and its termination.

Immunosuppression is a life-threatening complication of late cancer stages. In this regard, overproduction in the host plasma of the anti-inflammatory cyclopentenone prostaglandins (CP-PGs), which are strongly antiproliferative at high concentrations, may impair immune function. In fact, lymphoid tissues of tumour-bearing rats accumulated large amounts of CP-PGs while the tumour tissue itself did not. Expression of the CP-PG-induced 72-kDa heat shock protein (hsp70) was elevated in lymphocytes from tumour-bearing animals related to controls. As the capacity for CP-PG uptake by lymphocytes is the same as tumour cells, we investigated whether the latter could overexpress the multidrug resistance-associated protein (MRP1/GS-X pump) which extrudes CP-PGs towards the extracellular space as glutathione S-conjugates. Walker 256 tumour cells extruded 15-fold more S-conjugates than lymphocytes from the same rats (p < 0.001). This did not appear to be related to deficiency in lymphocyte glutathione (GSH) metabolism, since the major GSH metabolic routes are consistent with CP-PG conjugation in lymphocytes. This was not the case, however, for the MRP1/GS-X pump activity in lymphocyte membranes (in pmol/min/mg protein: 3.1 +/- 1.7 from normal rats, 0.2 +/- 0.2 from tumour-bearing animals vs 64.3 +/- 7.0 in tumour cells) which was confirmed by Western blot analysis for MRP1 protein. Transfection of lymphocytes with MRP1 gene completely abolished CP-PG (0-40 microM) toxicity. Taken together, these findings suggest that CP-PG accumulation in lymphocytes may be, at least partially, responsible for cancer immunodeficiency. Clinical approaches for overexpressing MRP1/GS-X pump in lymphocytes could then play a role as a tool for the management of cancer therapeutics.
