Prevalência de fatores de risco para doenças cardiovasculares entre escolares em Londrina - PR: diferenças entre classes econômicas

OBJETIVO: Avaliar e comparar a prevalência de fatores de riscos cardiovasculares em adolescentes escolares de diferentes classes econômicas. MÉTODOS: Foram avaliados 1.021 adolescentes. Os indivíduos foram pesados e tiveram sua altura e circunferência abdominal medidos, além da sua pressão arterial aferida. A prática de atividade física e condição socioeconômica foram relatadas. Os resultados foram avaliados pela utilização da frequência das variáveis e pelo teste do qui-quadrado. RESULTADOS: Observou-se menor prevalência de sedentarismo (p < 0,001) e maiores prevalências de obesidade abdominal (p = 0,038) e de sobrepeso (p = 0,010) entre adolescentes da classe econômica alta. Não houve diferença de prevalência de pressão arterial elevada entre adolescentes da classe econômica baixa e alta. Quando os fatores de risco cardiovasculares foram agregados, a prevalência também foi maior na classe econômica alta para um ou dois fatores de risco. CONCLUSÃO: Com exceção do sedentarismo e da pressão arterial elevada, a prevalência de fatores de risco para doenças cardiovasculares foi maior na classe econômica alta.

Complicações psiquiátricas do uso crônico do álcool: síndrome de abstinência e outras doenças psiquiátricas

A síndrome de abstinência alcoólica é um quadro agudo, caracterizado por um conjunto de sinais e sintomas autolimitados, com gravidade variada, secundário à interrupção total ou parcial do consumo de álcool, podendo ser associado a inúmeros problemas clínicos e/ou outros transtornos psiquiátricos. O objetivo deste artigo é rever as principais complicações psiquiátricas secundárias à síndrome de abstinência alcoólica, como convulsões e delirium tremens, bem como algumas outras condições psiquiátricas associadas à dependência de álcool, como as síndromes de Wernicke Korsakoff e de Marchiava Bignami. Pretende-se, com isso, auxiliar no diagnóstico precoce e tratamento adequado, minimizando assim a morbidade e a mortalidade associadas a tais complicações.

Resíduos de fentoato em tomate

The objective of the present research was to study the degradation and the persistence of phenthoate (Elsan 50 CE) residues in tomato fruits. The experiment was set in a tomato field located in Mombuca, State of São Paulo, Brazil, after 45 days from seedlings transplantation. Dosages of 600 (A), 800 (B), 1200 (C) and 1600 g a.i./ha (D) were sprayed at the beginning of the ripening period of fruits. Samples of 15 fruits each were collected 1, 4, 10, 20 and 40 days after products spraying. The utilized procedure consisted of extraction with acetone and purification by partition with dichloromethane. The purified extract was concentrated and injected into a gas chromatograph equipped with alkaly flame ionization detector (AFID). The limits of detection were of 0,01 ppm for this product. The recovery percentage from fortified samples varied from 60 to 81%. The degradation and the persistence half-lives were 1 to 2 and 3 to 6 days for phenthoate, respectively.

Potencial alelopático de Ipomoea fistulosa sobre a germinação de alface e tomate

The objective of the present research was to determine the allelopathic potential of Ipomoea fistulosa plants on germination and growth of seedlings. In laboratory, lettuce and tomato seeds were placed to germinate in the presence of water or Ipomoea fistulosa leaf extract, in the concentrations of 5, 10 e 15% (p/v). In greenhouse, seeds were placed to germinate in trays containing Plantmax (R) substrate and Plantmax (R) substrate + Ipomoea fistulosa dry leaf residue, at 3% (w/w). The aqueous extract inhibited germination, raised the mean germination time of the seeds and reduced the radicle and hypocotyl growth in all used concentrations. In greenhouse, the plant height, leaf number, and dry mass accumulation also were reduced in the presence of the leaf residue in the substrate. The results suggest the presence of allelochemicals in Ipomoea fistulosa and demonstrate the highest sensitivity of lettuce that tomato to these compounds.

Esporulação de Botryotinia ricini em diferentes meios de cultura

The castor bean plant is a tropical species and is subject to various diseases, which cause great losses. Among these diseases, the gray mold (Botryotinia ricini) is one of the most important. The fungus spore production was evaluated in the media of cultures BDA; Oats-Agar; Mazeina-Agar; Rice-Agar; castor-bean crushed leaves-agar (FM), FM-CaCO3; V8 juice to 5% (V8-5%); V8-10%; V8-20% and tomato juice at 5% (TJ-5%); TJ-10% and TJ-20%. The production of spore in different media of cultures was evaluated at 8(th) days of incubation. The data were analyzed using the comparison of means, through the test Tukey a 5% probability, and the data processed for (X + 1) (0.5). All means of crops tested were able to produce conidia, but the best results was obtained with the culture medium V8-20% (5.7 x 10(6) conidia/mL) and BDA (3.5 x 10(6) conidia/mL).

Doenças respiratórias em aves atendidas no laboratório de oriento- Patologia da FMVZ-UNESP/Botucatu-SP, Brasil, nos anos de 2005 A 2006

The respiratory tract of birds shows anatomical and physiological characteristics that facilitates the occurrence of disease, mainly those of microbiological origin. This article analyzes the frequency of respiratory diseases in domestic and wild birds treated during the years 2005-2006 at the Ornitopathology Laboratory of the Veterinary Hospital, Faculty of Veterinary Medicine and Zootecnics, São Paulo State University (FMVZUNESP). Diagnoses were obtained through clinical and radiographic exams as well as haemogram, microbiological culture, parasitological tests and necropsy, being septicemic processes, aspergillosis and mycoplasmosis the most diagnosed diseases. No zoonotic threats were identified, so the entities were described as of low-impact on public health. However, the above mentioned agents can provoke death of birds and difficult for treating and eradication as well.

Efeitos da adubação com manipueira sobre o rendimento e qualidade dos frutos de tomate

The objective of this research was to evaluate the residue from cassava, known as manipueira, as an alternative for tomato (Lycopersicon esculentum) fertilization. This experiment was carried out in UNESP with the cultivar Rio Grande. The experimental design was a completely randomized blocks in a 3 × 3 factorial arrangement with five blocks. Treatments constituted the following: 1) witness; 2) 54 m3/ha of manipueira; 3) 108 m3/ha of manipueira; 4) half recommended mineral fertilization; 5) half recommended mineral fertilization + 54 m3/ha of manipueira; 6) half recommended mineral fertilization + 108 m3/ha of manipueira; 7) recommended mineral fertilization; 8) recommended mineral fertilization + 54 m3/ha of manipueira and 9) recommended mineral fertilization + 108 m3/ha of manipueira. Tomato yield, number of fruits per plant, fruit diameter and lenght, total soluble solids (TSS), total titratable acidity (TTA) and the ratio TSS/TTA were evaluated. The results obtained indicated that manipueira contributed significantly to yield and quality of pos-harvested tomato fruits.

O sistema imune dos insetos e o controle de algumas doenças parasitárias humanas

Parasitic diseases in humans, transmitted by insects, affect about 500 million people living mainly in countries of low economic power. The control of these diseases is difficult to carry out, mianly due to social and political problems, enhanced by the capacity of these organisms to develop resistance to insecticides used to for their destruction. Some recent advances in the area of insect immunology have open the possibility for abetter epidemiological control of these diseases. The immune system of these insects, as well as that of other organisms, have the ability to recognize the infecting parasites and liberate a series of reactions which stop the infection. These reactions involve the circulating cells (hemocytes) against the parasite. These cells have the ability of phagocytize and liberate the production of various humoral factors, neutralizing the infection. Some promising results, obtained by the study of the immune system of malaria-transmitting insects, the sleeping disease, and dengue, are an example of this new sanitary strategy.

Espectro de agentes etiológicos associados a surtos de doenças transmitidas por alimentos em núcleos receptores turísticos de três regiões geográficas do Estado de São Paulo

Foodborne and waterborne diseases are spread by the consumption of food or water contaminated with bacteria and/or their toxins, viruses, parasites or chemicals. The aim of the research reported here was to establish the spectrum of etiologic agents of foodborne outbreaks at 15 tourist resorts in three geographic regions of the State of Sao Paulo (Brazil). The study was based on the cases reported to the Epidemic Surveillance Center (CVE) of the Public Health Authority of the State of São Paulo (SES), from 2002 to 2005. The tourist centers were chosen at random in three regions of the state (Capital, Interior and Coast) and offered the following attractions: events, agribusiness, cultural history, shopping, town center, gastronomy, health and leisure, sun and sea. Among the bacteria, the results showed that Salmonella spp. were most frequently associated with outbreaks, followed by Shigella spp., enterotoxigenic Escherichia coli, Staphylococcus aureus, Clostridium perfringens, Bacillus cereus and Campylobacter spp. Viruses (Rotavirus and Hepatitis A) played a part in many of the cases, while the frequency of parasites and worm infestations was low in the foodborne disease outbreaks at these resorts. The mixed foods (rice, beans, liver, potatoes, barbecue, juice), fish and poultry were the three commonest vehicles implicated in the outbreaks.

Fatores de risco para doenças cardiovasculares em idosos com diabetes mellitus tipo 2

The aim of this study was to analyze the risk factors related to the cardiovascular diseases (CVRF) in elderly type 2 diabetics. A cross-sectional observational study was carried out on 100 elderly patients attending the Rehabilitation Center of Araraquara (CRRA), São Paulo State, Brazil, from March to December, 2004. The majority were married, female, white, with a low income and low educational level. Regarding habits and style of life, the subjects had an adequate diet, were sedentary, non-smoking and non-drinking. In the population of 100, 42% were overweight, 42% obese, 71% had above-normal waist measurements and 84% high waist-to-hip ratios. Concerning the CVRF, it was observed that more than half had hypertension, hypercholesterolaemia and hypertriglyceridaemia. 84% had high values of LDL-cholesterol and 59% HDL-cholesterol levels below the reference values, 78% high levels of fasting glycemia, 76% glycohemoglobin and 57% fibrinogen and thus subject to cardiovascular risk. The results showed a high frequency of cardiovascular risk factors, differing according to sex and the age.
