Caracterização demográfica e formas clínicas apresentadas por crianças internadas com dengue em um hospital de referência da Amazônia
(Universidade Federal do Pará, 2012) TEIXEIRA, Kelly Soares; CRUZ, Ana Cecília Ribeiro; http://lattes.cnpq.br/8080838290715777
Dengue has been causing epidemics of different magnitudes in recent decades, and is present in almost all States of Brazil with movement of four different serotypes, from the introduction in the country of the serotype 4 in January, 2011. The current epidemiological scenario of the country indicates the elevation of severe forms of dengue in the pediatric age group. However, descriptive studies of cases of the disease in children, which make reference to epidemiological and clinical features, are infrequent. The present work is meant to show the demographic characteristics and clinical forms submitted by children under the age of twelve years, interned with dengue, in a referral hospital from Amazon. In this study, we used a methodology that would allow a search through retrospective analysis of hospitalized children with dengue, 154 patient records in the period between 2009 to 2011, in João de Barros Barreto University Hospital, in Belém, Pará. The variables examined were: age, gender, area of residence, distribution by municipalities, signs and symptoms, date of hospitalization, date of onset of symptoms, clinical form of the disease and platelet and hematocrit values, liver enzymes. In this study, there was no statistically significant difference between gender, most confirmed cases of dengue fever were coming from municipalities in the interior State of Pará (57.6%). Fever was the sign most often found (98.7%). Petechia was the hemorrhagic manifestation referred to as more frequent in this study (76.6%). Among the warning signs for Dengue Hemorrhagic Fever, abdominal pain and vomiting were present in 77.3% of patients. On the date of hospital admission, revealed that only after five to seven days from the beginning of the clinical symptoms, the patients had access to treatment in hospital. In this respect, it is known that the prognosis of patient with early recognition depends on dengue warning signals and immediate treatment with appropriate electrolytes spares. These results show that it is necessary to strengthen the basic health services in order to provide early diagnosis and appropriate care in the pediatric age group, in particular where dengue cases eventually are confused with other virus diseases prevalent in childhood. Certainly, there is a need to evaluate the efficiency of dengue control programs and application of specific measures to areas identified as priorities.

Um estudo sobre a migração de japoneses para a Amazônia peruana e sua continuação para a Amazônia brasileira
(Universidade Federal do Pará, 2014-05-29) SILVA NETO, Francisco Rodrigues da; ARAGÓN VACA, Luis Eduardo; http://lattes.cnpq.br/2713210031909963
The arrival of Japanese immigrants to Peru, aboard the ship Sakura Maru, in 1899, to work on the farms of the Peruvian coast, coincides with the heydays of rubber exploitation in the Amazon, which made this region attractive to migrants who did not remain in these farms. In the same year of the arrival of the ship Sakura Maru, 91 of these immigrants moved to the current department of Madre de Dios south of the Peruvian Amazon. After the cycle of exploitation of rubber, many Japanese immigrants remained in the Amazon and in Madre de Dios they settled around Puerto Maldonado, emerging a thriving Japanese community that remains up today. At the time of rubber exploitation some Japanese migrated to the current state of Acre (Brazil), called Peru kudari (those that descended from Peru), but few settled, spreading themselves, after the collapse of the rubber economy, to other places of Brazil and other countries. Thus, this thesis aims to demonstrate that migration of Japanese to the department of Madre de Dios in the Peruvian Amazon, and the emergence and consolidation of a Japanese community in Puerto Maldonado (capital of this department), were caused by three main factors: 1 ) a continuous policy in favor of Japanese immigration to Peru during the first decades of the twentieth century aimed to provide labor to the farms of sugar cane and cotton of the coast; 2) Involvement of Japanese immigrants in economic activities during the expansion of rubber exploitation in the Peruvian Amazon; and 3) Strengthening of these activities after the collapse of the rubber economy to ensure the supply of products required for the remaining population, including replacing of products imported or supplied by large companies. These factors were not found among Japanese who moved to Acre (Brazil), thus not getting the setting of Japanese communities that remained until today. The sources used in this study were composed of literature on international migration, data from the Peruvian and Brazilian censuses, newspapers of the time, diplomatic documents, and provincial reports, among others. The thesis is a study of historical demography using quantitative and qualitative data, in the quest to understand the historical process of the research object, in order to explain the developments that occurred in the communities of Japanese immigrants both in Madre de Dios (Peru) and Acre (Brazil).

Parâmetros demográficos de Micoureus demerarae (Didelphidae, Marsupialia) em áreas contíguas de manguezal e terra firme, Bragança, Pará, Brasil
(2007-06) ANDRADE, Fernanda Atanaena Gonçalves de; FERNANDES, Marcus Emanuel Barroncas; BRITO, Stélio Ângelo da Costa
This study investigated some aspects of the population dynamics of Micoureus demerarae (Thomas, 1905), such as: density, recruitment, and survivorship in two contiguous ecosystems, mangal and terra firme at the Fazenda das Salinas in the northeast of the state of Pará. One transect in each system was used for fieldwork. Data collection was carried out from November 2002 to September 2003. The following population parameters were estimated: density, recruitment, and survivorship. The results defined an open population with an even distribution for individuals from mangal and a clumped one for individuals from terra firme, and the evident seasonality with higher proportion of males in the terra firme. The reproductive period was the most important parameter to the population fluctuation in the beginning of the dry season. The environmental impacts over the population dynamics parameters of M. demerarae seem to be determinant for the maintenance of these populations.

Riqueza e dinâmica espaço-temporal de minhocas (Annelida, Oligochaeta) em um fragmento florestal.
(Universidade Federal do Pará, 2019-07-02) BECKMAN, Ruana Aretha Farias Santiago; LAVELLE, Patrick Marie; http://lattes.cnpq.br/5850683517396587; MARTINS, Marlúcia Bonifácio; http://lattes.cnpq.br/8882047165338427
The richness, distribution and abundance of Oligochaeta species were analyzed in relation to environmental parameters (internal forest precipitation, litter quantity, texture, pH and soil moisture) during 15 months in an area located in the peri-urban region of the municipality of Belém, state of Pará, Brazil, that belongs to Embrapa Eastern Amazon state company with a reserve area that corresponds to 2,706 hectares. In this study were found eight species: Pontoscolex corethrurus, Muller 1857, four species not been described yet and another 3 not determined due to the lack of characters required for identification. Species richness approached that found in other Amazon forest sites, however, most species occured in low abundance and with sparse distribution. It was also noted low functional diversity with all species belonging to the endogenous ecological category. In the study, the predominant species was Pontoscolex corethrurus, which represented 96.94% of the total density while the others summed up 3.06%. P. coretrhurus was dominant in all points in the site and in all periods. Because of this, it was the only species studied in relation to soil and climate attributes. In this study their abundance responded significantly to the internal precipitation while litter quantity, soil texture, pH and soil moisture did not show considerable effects. Demographics showed that this is an Oligochaeta species that can remain on the soil all year long. It also mantains continued population development with their cocoons producing in three months of year. Although the number of species detected did not show drastic reduction, the high dominance of P. corethrurus, the low functional diversity, the rarity and dispersion of native species spatio-temporal distributions offer clear indications for biodiversity loss in soil fauna in this forest remnant. Possibly this is accompanied by loss of soil ecosystem functions, because of isolation and surrounding urbanization.
