Trends in Mortality Rate from Cardiovascular Disease in Brazil, 1980-2012

Abstract Background: Studies have questioned the downward trend in mortality from cardiovascular diseases (CVD) in Brazil in recent years. Objective: to analyze recent trends in mortality from ischemic heart disease (IHD) and stroke in the Brazilian population. Methods: Mortality and population data were obtained from the Brazilian Institute of Geography and Statistics and the Ministry of Health. Risk of death was adjusted by the direct method, using as reference the world population of 2000. We analyzed trends in mortality from CVD, IHD and stroke in women and men in the periods of 1980-2006 and 2007-2012. Results: there was a decrease in CVD mortality and stroke in women and men for both periods (p < 0.001). Annual mortality variations for periods 1980-2006 and 2007-2012 were, respectively: CVD (total): -1.5% and -0.8%; CVD men: -1.4% and -0.6%; CVD women: -1.7% and -1.0%; DIC (men): -1.1% and 0.1%; stroke (men): -1.7% and -1.4%; DIC (women): -1.5% and 0.4%; stroke (women): -2.0% and -1.9%. From 1980 to 2006, there was a decrease in IHD mortality in men and women (p < 0.001), but from 2007 to 2012, changes in IHD mortality were not significant in men [y = 151 + 0.04 (R2 = 0.02; p = 0.779)] and women [y = 88-0.54 (R2 = 0.24; p = 0.320). Conclusion: Trend in mortality from IHD stopped falling in Brazil from 2007 to 2012.

Três novas espécies sul-americanas de Cryptachaea e acréscimos taxonômicos em Achaearanea (Araneae, Theridiidae)

Três espécies de Cryptachaea Archer, 1946 são descritas, duas delas para o Brasil: C. amazonas sp. nov. da Reserva Florestal Adolpho Ducke, Manaus, Amazonas e Cryptachaea maldonado sp. nov. da Base de Operações Geólogo Pedro de Moura, Porto Urucu, rio Urucu, Coari, Amazonas, com base em machos. Uma nova associação de macho e fêmea é proposta para Achaearanea hieroglyphica (Mello-Leitão, 1940). O macho da Guiana Francesa, atribuído à última espécie, é considerado uma espécie nova de Cryptachaea, C. ingijonathorum. O macho de Achaearanea tingo Levi, 1963 é descrito pela primeira vez. Novas ocorrências são listadas para A. trapezoidalis (Taczanowski, 1873).

Dados estatísticos de viscerotomia sobre doenças e condições mórbidas do homem no Brasil: I. Schistosomose Mansônica no período de 1937-1946

Examination of 267.107 liver specimens obtained in Brazil by viscerotomy during from 1937 to 1946 inclusive revealed 5,953 Schistosoma mansoni infe¬ctions. This represents 2.23% ± 0.019 of the total number of livers studied. Data on the incidence of the disease is tabulated by states and municipios. Infected livers were found in all of the states and territories except the Territory of Amapá. Schistosomiasis is widespread in Brazil with highest incidence in the states of the Northeast. The disease is quite common in Espírito Santo and Minas Gerais as well. A study of the age distribution of cases of intestinal schistosomiasis observed among liver specimens obtained in the year 1938 showed a low inci¬dence on young children with a peak of prevalence in the 10 to 19 year age group. The purpose of this contribution is to call attention of the health autho¬rities to the extent and gravity of the problem of intestinal schistosomiasis in Brazil.

Trematódeos monogenéticos (Polistomatas) da costa brasileira I. sobre Loimos scitulus sp. n. (Loimoidae) e Tagia ecuadori (Meserve, 1938) Sproston, 1946 (Diclidophoridae)

Em continuação aos estudos dos trematódeos monogenéticos da Coleção Helmintológica do Instituto Oswaldo Cruz, descrevemos no presente trabalho uma espécie do gênero Loimos MacCallum, 1917, Loimolinae Price, 1936, loimoidae Bychowsky, 1957 que consideramos nova para a ciência, e assinalamos nova ocorrência de Tagia ecuadori (Meserve, 1938) Sproston, 1946, Tagiinae Yamaguti, 1963, Diclidophoridae Najibina & Obonikova, 1971, no Atlântico Sul. Loimos scitulus sp. n. diferencia-se das outras espécies do gênero pelos seguintes caracteres: forma e estrututra do proaptor, oótipo grande, número de testículos, posição do poro genital, filamento do ovo e forma de opistaptor. Dentre as diferenças dadas Loimos scitulus sp. n. aproxima-se de L. salpinggoides pela estrutura do proaptor, de L. secundus pela posição do poro genital; de L. winteri pelo opistaptor. Quanto aos exemplares de Tagia ecuadori por nós estudados, apesar de ter sido evidenciada uma vagina, identificamos a esta espécie, por apresentar estruturas e medidas que se enquadram nas variações dadas pelos estudiosos do grupo.

First report of Ascarophis Van Beneden, 1871: A. Brasiliensis n.sp. (Nematoda, Ascarophidinae) and Procamallanus (Spirocamallanus) Pereira/Annereaux, 1946 (Nematoda, Procamallaninae) in South America

Ascarophis brasiliensis recovered from the stomach of Trachinotus carolinus (L. 1766), is proposed as a new species and Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 is redescribed from a new host: Paralonchurus brasiliensis (Steind., 1875). A. brasiliensis is more closely related to A. crassicolis Dollfus & Campana-Rouget, 1956, from which it differs mainly by the absence of cervical cuticular expansion and size of the eggs. The new species is also compared to A. cooperi johnston & Mawson, 1945 and A. girellae (Yamaguti, 1935) Campana-rouget, 1955. The validity of the proposed species is discussed.

Studies on Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 (Nematoda: Camallanidae), with new host records and new morphological data on the larval stages

Larval stages and adults of Procamallanus (Spirocamallanus) pereirai Annereaux, 1946 are described from naturally infected Paralonchurus brasiliensis (Steindachner) (Sciaenidae) from the coast of the State of Rio de Janeiro, Brazil. The translucent first-stage larvae have a denticulate process at the anterior end, no buccal capsule or esophagus undifferentiated into anterior muscular and posterior glandular parts and an elongate tail; third-stage larvae have a tail with three terminal projections, a buccal capsule divided into an anterior portion with 12-20 ridges running to the left and a posterior smooth portion, and an esophagus with muscular and glandular regions. Fourth-stage larvae exhibit a buccal capsule lacking a distinct basal ring with ridges running to the right and a tail with two terminal processes, as in adults. New host records are reported and their role in its life-cycle are discussed.

Transmitted human immunodeficiency virus-1 drug resistance in a cohort of men who have sex with men in Belo Horizonte, Brazil - 1996-2012

The presence of transmitted human immunodeficiency virus (HIV)-1 drug-resistance (TDR) at the time of antiretroviral therapy initiation is associated with failure to achieve viral load (VL) suppression. Here, we report TDR surveillance in a specific population of men who have sex with men (MSM) in Belo Horizonte, Brazil. In this study, the rate of TDR was evaluated in 64 HIV-infected individuals from a cohort of MSM between 1996-June 2012. Fifty-four percent had a documented recent HIV infection, with a seroconversion time of less than 12 months. The median CD4+T lymphocyte count and VL were 531 cells/mm3and 17,746 copies/mL, respectively. Considering the surveillance drug resistance mutation criteria, nine (14.1%) patients presented TDR, of which three (4.7%), five (7.8%) and four (6.2%) had protease inhibitors, resistant against nucleos(t)ide transcriptase inhibitors and against non-nucleoside reverse-transcriptase inhibitors mutations, respectively. Two of the patients had multi-drug-resistant HIV-1. The most prevalent viral subtype was B (44, 68.8%), followed by subtype F (11, 17.2%). This study shows that TDR may vary according to the population studied and it may be higher in clusters of MSM.
