O canto do cisne no retorno do Eu ao Ato da escrita. Estudo comparativo de testemunho de José Cardoso Pires e de José Luis Sampedro

Este trabalho com o título «O Canto do Cisne no Retorno do Eu ao Ato da Escrita» é um estudo comparativo que pretende investigar o fenómeno da criatividade literária na primeira pessoa, de um universo literário não convencional devidamente identificado, de acordo com a matriz dos testemunhos selecionados. O corpus principal do trabalho são dois livros de natureza biográfica, de dois escritores ibéricos, cujo propósito é testemunhar na primeira pessoa a experiência limite causada por grave fragilidade física. Não obstante o problema diagnosticado, os dois autores puderam, a seu tempo, pôr à prova a própria recuperação física e o estado de capacidade literária ao retomarem o ato da escrita para testemunharem com intimidade confessional a inevitabilidade do ato da escrita de escritores com percurso sério feito, no limite da precariedade da existência humana. A atividade literária dos autores é a sustentação indagativa para a fase adiantada de maturidade interpretativa revelada no corpus escolhido. José Cardoso Pires e José Luis Sampedro são dois “cisnes” que puderam e souberam “cantar” a conquista, ainda que temporária, sobre a morte, explicando com lucidez, cada um a seu modo, a sua experiência de finitude física, diria que em nome de todos os que, em situações análogas, gostariam de o ter feito; numa vontade exponenciada pela experiência do desconhecido, como o filósofo Paul Ricoeur que procurou testemunhar na sua escrita a experiência na primeira pessoa da finitude em estado de moribundo.A contribuição original deste trabalho para o conhecimento não se confina ao levantamento e análise comparativa dos testemunhos pessoais destes escritores de renome e de subida atividade sobre a necessidade vital e inventiva de escrever, nem tão pouco ao valor documental literário dos mesmos para a compreensão do fenómeno da atividade criativa, com e para as outras áreas do saber; remete também para o universo subsequente à receção das suas obras, às reações literárias e públicas envolventes, a depoimentos sobre o fenómeno do ato da escrita literária e à importância para o fenómeno da palavra escrita para a autopreservação física, intelectual, social e afetiva. A seleção do corpus de autores latinos contemporâneos foi feita de acordo com a contemporaneidade e a proximidade geocultural de ambos. Embora estes escritores não se conhecessem, a que tudo indica pessoalmente, tinham um importante amigo comum, José Saramago, com o qual partilhavam os mesmos ideais de justiça social. São dois altos representantes das literaturas portuguesa e espanhola conscientes da importância da cultura vizinha. Como o foram José Saramago e Miguel Unamuno.

Prevalence of HCV infection and associated factors among illicit drug users in Breves, State of Pará, northern Brazil

Introduction: Illicit drug users (DUs) are vulnerable to hepatitis C virus (HCV) infection. The shared use of illicit drugs is the main method of HCV transmission. Methods: A cross-sectional study was conducted in Breves, in northern Brazil. We surveyed 187 DUs to determine the prevalence of and factors associated with HCV infection. Results: The prevalence of anti-HCV antibodies was 36.9%, and the prevalence of hepatitis C virus-ribonucleic acid (HCV-RNA) was 31%. Hepatitis C virus infection was associated with tattoos, intravenous drug use, shared use of equipment for drug use, drug use for longer than 3 years, and daily drug use. Conclusions: Strategies for preventing and controlling HCV transmission should be implemented among DUs.

Causes of hospital admission of AIDS patients in southern Brazil, 2007 to 2012

IntroductionThe acquired immunodeficiency syndrome (AIDS) epidemic is a worldwide phenomenon that has been modified with the implementation of effective antiretroviral therapy. The objective of this study was to determine the leading causes of hospitalization among human immunodeficiency virus (HIV)-positive individuals.MethodsA cross-sectional study with patients admitted to a general hospital in southern Brazil, between January 2007 and May 2012.ResultsMedical records of 550 hospital admissions (230 patients) were reviewed, with an average of 2.4 hospitalizations per patient. Infectious diseases were the most prevalent causes of hospitalization. Overall, 44.8% patients died and their deaths were associated with longer hospital stays.ConclusionsOpportunistic infections remained the leading causes of hospitalization.

Leprosy and pregnancy: detection coefficient and proposal for a new index

Introduction Our study presents a method to generate a novel detection coefficient for the association between leprosy and pregnancy (DCLP). Methods The DCLP was calculated for women from the State of Pará (2007-2009), Brazil. Data were ordered, divided into five equal parts (corresponding to the P20, P40, P60, and P80 percentiles), and classified as low, medium, high, very high, or hyperendemic. Results Using the new index, we established the DCLP parameters for low (<0.36), medium (0.36-0.69), high (0.70-1.09), very high (1.10-1.50), and hyperendemic (>1.50). Conclusions The new DCLP is more appropriate than the overall detection coefficient (DC), which does not take into account the particularities of the interaction between a disease and a specific physiological state.

The epidemiology of envenomation via snakebite in the State of Piauí, Northeastern Brazil

INTRODUCTION: This communication describes a retrospective study of the epidemiology of snakebite cases that were recorded from 2007 to 2012 in the State of Piauí, northeastern Brazil. METHODS: Data were collected from the Injury Notification Information System database of the State of Piauí's Health Department. RESULTS: A total of 1,528 cases were identified. The cases occurred most frequently in rural areas between January and July. Victims were predominantly male farmers, and were typically 30-39 years old. Most victims were bitten on the foot, and received medical assistance within 1-3h after being bitten. CONCLUSIONS: The epidemiological profile of snakebites in the State of Piauí is similar to that in all of Brazil.

Occurrence of Cryptosporidium spp., Giardia spp. and other pathogenic intestinal parasites in the Beberibe River in the State of Pernambuco, Brazil

INTRODUCTION: Transmission of pathogenic protozoa and helminths by water is a serious public health problem. In this study, we analyzed the presence of these organisms in the Beberibe River in Pernambuco, Brazil. METHODS: Parasite analysis was performed using the Hoffman, Pons, & Janer method followed by centrifugation and preparation of slides by staining with acetic acid and Lugol's solution. Protozoan oocysts were isolated by the modified Ziehl Neelsen method. RESULTS: Cryptosporidium spp., Giardia spp. and other parasites were found in the Beberibe River. CONCLUSIONS: Sanitation companies must assess pathogenic intestinal parasites in water basins providing public water and subsequently develop improved treatment systems for removal of such parasites.

Os efeitos das campanhas negativas mediáticas no ato eleitoral: caso José Sócrates nas legislativas 2009 e 2011

Nos dias de hoje, o marketing político e a assessoria de imprensa tornaram-se ferramentas essenciais para um político. Sem estas ferramentas nenhum político seria capaz de responder às exigências da imagem que o século XXI acarreta. Uma boa imagem/reputação são fatores chave para o sucesso eleitoral de qualquer candidato. Em Portugal, os media são o principal palco de visualização e obtenção de conhecimento das questões políticas pela maioria das pessoas. Políticos e media devem andar de “mãos dadas”. Os media podem tornar-se os principais “inimigos” de um político. Que contornos e proporções poderão tomar uma “campanha negativa” desencadeada pelos media a um político em plena campanha eleitoral? Através de um estudo de caso iremos perceber os seus efeitos e consequências mediáticas, nas legislativas de 2009 e 2011 de José Sócrates.

First report of schistosomiasis on Serrambi beach, Ipojuca, State of Pernambuco

Abstract: INTRODUCTION : The expansion of schistosomiasis to previously unaffected areas is being monitored by identifying new cases and georeferencing outbreaks of vector snails. METHODS : In 2014, the Laboratório de Esquistossomose began an epidemiological survey in Serrambi and registered 2,574 people living there. RESULTS : Of these subjects, 1,414 (54.9%) underwent feces examination and 63 (4.5%) were diagnosed with Schistosoma mansoni infection. At this locality, seven breeding sites each were identified for Biomphalaria straminea and Biomphalaria glabrata. At two sites, B. glabrata were shedding cercariae. CONCLUSIONS : Implementing preventive measures is necessary to avoid the establishment of schistosomiasis in yet another tourist locality, Pernambuco.

Pilot study with a glutamine-supplemented enteral formula in critically ill infants

Seriously ill infants often display protein-calorie malnutrition due to the metabolic demands of sepsis and respiratory failure. Glutamine has been classified as a conditionally essential amino acid, with special usefulness in critical patients. Immunomodulation, gut protection, and prevention of protein depletion are mentioned among its positive effects in such circumstances. With the intent of evaluating the tolerance and clinical impact of a glutamine supplement in seriously ill infants, a prospective randomized study was done with nine patients. Anthropometric and biochemical determinations were made, and length of stay in the intensive care unit (ICU), in the hospital, and under artificial ventilation, and septic morbidity and mortality were tabulated. Infants in the treatment group (n=5) were enterally administered 0.3 g/kg of glutamine, whereas controls received 0.3 g/kg of casein during a standard period of five days. Septic complications occurred in 75% of the controls (3/4) versus 20% of the glutamine-treated group (1/5, p<=0.10), and two patients in the control group died of bacterial infections (50% vs. 0%, p<=0.10). Days in the ICU, in the hospital, and with ventilation numerically favored glutamine therapy, although without statistical significance. The supplements were usually well tolerated, and no patient required discontinuation of the program. The conclusion was that glutamine supplementation was safe and tended to be associated with less infectious morbidity and mortality in this high-risk population.

Intraventricular hemorrhage in very low birth weight infants: associated risk factors and outcome in the neonatal period

Intraventricular hemorrhage (IVH) is a severe complication in very low birth weight (VLBW) newborns (NB). With the purpose of studying the incidence of IVH, the associated risk factors, and the outcomes for these neonates, we studied all the VLBW infants born in our neonatal unit. Birth weight, gestational age, presence of perinatal asphyxia, mechanical ventilation, length of hospitalization, apnea crisis, hydrocephalus, and periventricular leukomalacia were analyzed. The diagnosis of IVH was based on ultrasound scan studies (Papile's classification) performed until the tenth day of life and repeated weekly in the presence of abnormalities. Sixty-seven/101 neonates were studied. The mortality rate was 30.6% (31/101) and the incidence of IVH was 29.8% (20/67) : 70% grade I, 20% grade III and 10% grade IV. The incidence of IVH in NB <1,000 g was 53.8% (p = 0.035) and for gestational age <30 weeks was 47.3% (p = 0.04), both considered risk factors for IVH. The length of hospitalization (p = 0.00015) and mechanical ventilation (p = 0.038) were longer in IHV NB. The IVH NB had a relative risk of 2.3 of developing apnea (p = 0.02), 3.7 of hydrocephalus (p = 0.0007), and 7.7 of periventricular leukomalacia (p < 0.00001). The authors emphasize the importance of knowing the risk factors related to IVH so as to introduce prevention schemes to reduce IVH and to improve outcomes of affected newborns.

Efeito de background local e assinatura geoquímica de anomalias naturais em sedimentos de corrente e solos – aplicação à área envolvente do jazigo de urânio (Nisa, Portugal)

Na região de Nisa, concelho de Portalegre, situa-se um dos maiores e mais relevantes jazigos de urânio alguma vez descoberto em território nacional. Trata-se de um jazigo ainda inexplorado que encerra um potencial estimado em cerca de 32 milhões de toneladas de minério tal qual. Este jazigo ocorre à superfície e encontra-se em contexto metassedimentar embutido em xistos mosqueados, pertencentes ao Grupo das Beiras, nas proximidades do contacto com o granito do Maciço de Nisa. Este trabalho tem como objetivo estudar de forma qualitativa e quantitativa a dispersão geoquímica provocada por processos naturais de erosão e de transporte hidrogravítico na envolvente à anomalia geoquímica natural localmente induzida por este jazigo. Para o efeito estabeleceu-se uma metodologia com as seguintes etapas principais: (1) georreferenciação em SIG de elementos de cartografia; (2) planeamento e elaboração do plano de amostragem; (3) recolha e tratamento de amostras de solos e sedimentos; (4) ensaios não destrutivos de medição de radiação gama por SPP2 e determinações analíticas por XRF; (5) análise exploratória e tratamento estatístico de dados e análise espacial; (6) análise de resultados; (7) definição de teores geoquímicos de fundo local. As amostras de sedimentos foram retiradas de uma ribeira que intersecta a área da anomalia e alimenta uma barragem local de enrocamento; as amostras de solos foram retiradas de linhas de amostragem perpendiculares à ribeira. As determinações analíticas registaram os teores em diversos metais, como o urânio, crómio, molibdénio, nióbio, vanádio e zinco e do semimetal arsénio. Com exceção do zinco, os resultados evidenciam que as concentrações naturais nestes metais no local onde se localiza uma importante jazida de minérios de urânio são muito elevados, e quando comparados com os valores standard da norma Canadiana mostram poder existir risco para a saúde se não forem limitados os usos do local.

Potencial do Sienito Nefelínico de Monchique para incorporação na indústria cerâmica

A procura de novos materiais aumenta dia após dia, obrigando o Homem a procurar e encontrar novas soluções, tendo sempre como critério decisivo, uma exploração económica e ambiental sustentável. É neste âmbito que surge o tema desta dissertação. O objetivo é tirar um maior proveito do sienito nefelínico de Monchique (Portugal), à semelhança de países como a Rússia, Canadá e Noruega, que utilizam esta rocha a nível industrial. Neste trabalho, a investigação foi no sentido de estudar o potencial da rocha portuguesa para a indústria cerâmica. O elevado teor de alumina e álcalis que o sienito nefelínico apresenta na sua constituição, serve de substituto aos minerais atualmente utilizados neste sector, os feldspatos isolados. A alumina serve de estabilizador, promovendo a durabilidade dos materiais pelo aumento da resistência e o conteúdo em álcalis funciona como fundente, diminuindo a temperatura de queima. Desta forma, o Maciço de Monchique ganha uma nova importância económica, sendo uma mais-valia para o país. Para tal, elaboraram-se provetes cerâmicos constituídos por 0, 20, 40 e 60% em peso de sienito nefelínico em mistura com argila. Posteriormente, sujeitaram-se os provetes a três temperaturas diferentes, 900 °C, 1000 °C e 1100 °C e submeteram-se cada um deles a ensaios físicos e mecânicos, para determinar o potencial da incorporação do sienito de Monchique na indústria cerâmica. Os resultados indicaram que a adição de sienito nefelínico melhora as propriedades físicas da argila. Relativamente às propriedades mecânicas, o ensaio de resistência à flexão indicou que, dos vários teores testados, o mais positivo encontra-se na percentagem de 20% de sienito nefelínico, apresentando valores próximos da argila pura utilizada como referência.

Changes in body fluid and energy compartments during prolonged hunger strike

Prolonged total food deprivation in non-obese adults is rare, and few studies have documented body composition changes in this setting. In a group of eight hunger strikers who refused alimentation for 43 days, water and energy compartments were estimated, aiming to assess the impact of progressive starvation. Measurements included body mass index (BMI), triceps skinfold (TSF), arm muscle circumference (AMC), and bioimpedance (BIA) determinations of water, fat, lean body mass (LBM), and total resistance. Indirect calorimetry was also performed in one occasion. The age of the group was 43.3±6.2 years (seven males, one female). Only water, intermittent vitamins and electrolytes were ingested, and average weight loss reached 17.9%. On the last two days of the fast (43rd-44th day) rapid intravenous fluid, electrolyte, and vitamin replenishment were provided before proceeding with realimentation. Body fat decreased approximately 60% (BIA and TSF), whereas BMI reduced only 18%. Initial fat was estimated by BIA as 52.2±5.4% of body weight, and even on the 43rd day it was still measured as 19.7±3.8% of weight. TSF findings were much lower and commensurate with other anthropometric results. Water was comparatively low with high total resistance, and these findings rapidly reversed upon the intravenous rapid hydration. At the end of the starvation period, BMI (21.5±2.6 kg/m²) and most anthropometric determinations were still acceptable, suggesting efficient energy and muscle conservation. Conclusions: 1) All compartments diminished during fasting, but body fat was by far the most affected; 2) Total water was low and total body resistance comparatively elevated, but these findings rapidly reversed upon rehydration; 3) Exaggerated fat percentage estimates from BIA tests and simultaneous increase in lean body mass estimates suggested that this method was inappropriate for assessing energy compartments in the studied population; 4) Patients were not morphologically malnourished after 43 days of fasting; however, the prognostic impact of other impairments was not considered in this analysis.

Intestinal intussusception and occlusion caused by small bowel polyps in the Peutz-Jeghers syndrome. Management by combined intraoperative enteroscopy and resection through minimal enterostomy: case report

The Peutz-Jeghers syndrome is a hereditary disease that requires frequent endoscopic and surgical intervention, leading to secondary complications such as short bowel syndrome. CASE REPORT: This paper reports on a 15-year-old male patient with a family history of the disease, who underwent surgery for treatment of an intestinal occlusion due to a small intestine intussusception. DISCUSSION: An intra-operative fiberscopic procedure was included for the detection and treatment of numerous polyps distributed along the small intestine. Enterotomy was performed to treat only the larger polyps, therefore limiting the intestinal resection to smaller segments. The postoperative follow-up was uneventful. CONCLUSION: We point out the importance of conservative treatment for patients with this syndrome, especially those who will undergo repeated surgical interventions because of clinical manifestation while they are still young.
