Após seis meses de atuação, obteve-se um resultado significativo na redução da medicação necessária para o controle glicêmico e uma diminuição no surgimento de novos casos de diabetes.

Planejamento da Equipe Saúde da Famíla: ferramenta para prevenir e diminuir a incidência da gastroenterite em Matias Cardoso - MG

A gastroenterite, ou doença diarréica, uma patologia que tem forte incidência na infância, é uma das principais causas de morbidade e mortalidade infantil em crianças menores de cinco anos de idade, principalmente em países subdesenvolvidos e em desenvolvimento, por envolver uma série de fatores ambientais, econômicos e sócio-culturais. Em Matias Cardoso/MG, observa-se uma alta prevalência de gastroenterites na população pediátrica, com maior incidência entre as crianças de 0 a 2 anos. O presente trabalho foi elaborado a partir do estudo dos dados expostos em relatório construído pela Coordenação da Vigilância Epidemiológica do município. A análise das fichas de notificação das doenças diarréicas agudas do PSF Nossa Senhora da Glória durante os três primeiros meses de 2013 demonstraram que a alta incidência de gastroenterite na área estudada requeria decisões e ações imediatas. Foram então realizadas reuniões com os membros de todas as equipes de saúde do PSF para reforçar a importância da notificação de todos os casos de doenças diarréicas, para assegurar que medidas de controle fossem adotadas com prontidão e efetividade. Para tal foi elaborado um plano de intervenção visando diminuir a incidência de gastroenterite pediátrica. Na implementação do referido plano o método proposto foi o Planejamento Estratégico Situacional (PES), com ações práticas, além de ações educativas. Foram adotadas a distribuição de colheres medidoras para o preparo do soro caseiro e solução clorada para tratamento da água de consumo e distribuição de filtros para a população com maior vulnerabilidade às doenças diarréicas. As ações foram realizadas em parceira com as Secretarias Municipais de Saúde e de Ação Social, assim como de empresários e fazendeiros que residem no território. Os resultados das ações demonstraram que houve aumento da utilização do soro caseiro no tratamento da desidratação, assim como aumento para 100% dos moradores que fazem uso de água filtrada ou tratada, um importante passo para a prevenção desta e de outras doenças que estão relacionadas com a qualidade da água utilizada pela população.

Mesenchymal Stromal Cells From Adipose Tissue Attached To Suture Material Enhance The Closure Of Enterocutaneous Fistulas In A Rat Model.

Surgical treatment for enterocutaneous fistulas (EF) frequently fails. Cell therapy may represent a new approach to treatment. Mesenchymal stromal cells (MSCs) have high proliferative and differentiation capacity. This study aimed to investigate whether MSCs could adhere to suture filament (SF), promoting better EF healing. MSCs, 1 × 10(6), from adipose tissue (ATMSCs) were adhered to a Polyvicryl SF by adding a specific fibrin glue formulation. Adhesion was confirmed by confocal and scanning electron microscopy (SEM). A cecal fistula was created in 22 Wistar rats by incising the cecum and suturing the opening to the surgical wound subcutaneously with four separate stitches. The animals were randomly allocated to three groups: control (CG)-five animals, EF performed; injection (IG)-eight animals 1 × 10(6) ATMSCs injected around EF borders; and suture filament (SG): nine animals, sutured with 1 × 10(6) ATMSCs attached to the filaments with fibrin glue. Fistulas were photographed on the operation day and every 3 days until the 21st day and analyzed by two observers using ImageJ Software. Confocal and SEM results demonstrated ATMSCs adhered to SF (ATMSCs-SF). The average reduction size of the fistula area at 21st day was greater for the SG group (90.34%, P < 0.05) than the IG (71.80%) and CG (46.54%) groups. ATMSCs adhered to SF maintain viability and proliferative capacity. EF submitted to ATMSCs-SF procedure showed greater recovery and healing. This approach might be a new and effective tool for EF treatment.

Factors associated with the prevalence of hypertension and control practices among elderly residents of São Paulo city, Brazil

The aim of this study was to analyze the prevalence of hypertension and control practices among the elderly. The survey analyzed data from 872 elderly people in São Paulo, Brazil, through a cluster sampling, stratified according to education and income. A Poisson multiple regression model checked for the existence of factors associated with hypertension. The prevalence of self-reported hypertension among the elderly was 46.9%. Variables associated with hypertension were self-rated health, alcohol consumption, gender, and hospitalization in the last year, regardless of age. The three most common measures taken to control hypertension, but only rarely, are oral medication, routine salt-free diet and physical activity. Lifestyle and socioeconomic status did not affect the practice of control, but knowledge about the importance of physical activity was higher among those older people with higher education and greater income. The research suggests that health policies that focus on primary care to encourage lifestyle changes among the elderly are necessary.

Thermolysed and active yeast to reduce the toxicity of aflatoxin

Aflatoxins are hepatotoxic metabolites produced by Aspergillus flavus and A. parasiticus on a number of agricultural commodities. This research was carried out to evaluate the ability of thermolysed and active Saccharomyces cerevisiae to attenuate liver damage caused by aflatoxin. Diets were prepared containing 0 aflatoxin; 400 mug kg-1 aflatoxin; 400 mug kg-1 aflatoxin plus 1% of dehydrated active yeast, and 400 mug kg-1 aflatoxin plus 1% of thermolysed yeast. A bioassay with Wistar rats was conducted for 28 days, and body organs were weighted and analyses of the liver tissue of the animals were performed. The relative weight of heart, kidneys and liver from animals submitted to the different treatments did not show any difference, and liver tissue of animals feeding on the aflatoxin-free diet was adopted as a toxicity-free pattern. Hepatic tissue of animals feeding on diets containing 400 mug kg-1 aflatoxin or the diet supplemented with 1% thermolysed yeast showed clear signs of toxicity and damage. Hepatic tissue of animals feeding on the diet containing 1% of dehydrated active yeast showed less toxicity signs and damage than those receiving the diet containing 400 mug kg-1 aflatoxin. Active, dehydrated yeast had the ability to reduce toxic effects caused by aflatoxin, but thermolysed yeast was not able to alleviate the effects of aflatoxin toxicity.

Jaguarundi (Puma yagouaroundi) (Geoffroy, 1803) (Carnivora, Felidae) food habits in a mosaic of Atlantic Rainforest and eucalypt plantations of southeastern Brazil

Food habits of jaguarundi (Puma yagouaroundi) (Geoffroy, 1803) (Carnivora, Felidae) were studied between November 2000 and November 2001, in a 24.9 km² area of secondary Atlantic Rainforest and eucalypt plantation, in the Serra de Paranapiacaba, São Paulo State, Brazil. Analyses of 26 fecal and regurgitate samples, obtained over a stretch of 570.1 km, showed the consumption of 19 prey items and 74 prey occurrences. Small mammals were the most frequent food item (42.5%), followed by birds (21%), reptiles (14%) and medium-sized mammals (3%). The percent occurrence (PO) suggests that the diet consisted mainly of small rodents (30%) and birds (21%). We recorded for the first time the predation of Viperidae snakes by P. yagouaroundi. Although having a large list of items and range of dietary niche breadths (Bsta = 0.76), our data show that jaguarundi prey mainly on small vertebrates (mammals, birds or reptiles), and even in tall tropical forests or eucalypt plantations, it preys mostly on animals that come to, or live on, the ground.

Are skeletally mature female rats a suitable model to study osteoporosis?

OBJECTIVE: To analyze if female Wistar rats at 56 weeks of age are a suitable model to study osteoporosis. MATERIALS AND METHODS: Female rats with 6 and 36 weeks of age (n = 8 per group) were kept over a 20-week period and fed a diet for mature rodents complete in terms of Ca, phosphorous, and vitamin D. Excised femurs were measured for bone mass using dual-energy x-ray absorptiometry, morphometry, and biomechanical properties. The following serum mar-kers of bone metabolism were analyzed: parathyroid hormone (PTH), osteocalcin (OC), osteoprotegerin (OPG), receptor activator of nuclear factor Κappa B ligand (RANKL), C-terminal peptides of type I collagen (CTX-I), total calcium, and alkaline phosphatase (ALP) activity. RESULTS: Rats at 56 weeks of age showed important bone metabolism differences when compared with the younger group, such as, highest diaphysis energy to failure, lowest levels of OC, CTX-I, and ALP, and elevated PTH, even with adequate dietary Ca. CONCLUSION: Rats at 26-week-old rats may be too young to study age-related bone loss, whereas the 56-week-old rats may be good models to represent the early stages of age-related changes in bone metabolism.

Dental caries and related factors in Brazilian children from fluoridated and non-fluoridated areas

PURPOSE: To compare the caries prevalence, saliva buffering capacity (SBC), oral hygiene (OH), dietary habits, family income (FI) and frequency of visits to a dental office (Do) between Brazilian children living in areas with and without fluoridated public water supply. METHODS: Forty-six 5-7-year-old preschoolers were selected in Itatiba, SP, Brazil; 19 were from a fluoridated area, and 27 were from a non-fluoridated area. The caries index was determined according to the World Health Organization criteria, and the SBC was assessed by titration with hydrochloric acid. The FI, frequency of OH and visits to Do were estimated by questionnaire. The dietary habits were assessed with a diet chart. The differences between the groups were analyzed with Mann-Whitney-U tests (α=0.05). RESULTS: Children from the non-fluoridated area showed significantly higher dmft/DMFT than those from the fluoridated area, but they showed significantly lower SBC, OH frequency and FI. No significant differences were observed between the areas for dietary habits and visits to Do. CONCLUSION: Children from fluoridated areas showed higher salivary buffering capacity, family income and oral hygiene frequency as well as lower caries prevalence, supporting the beneficial effect of fluoride in the tap water for caries prevention.

Oral findings and dental care in a patient with myelomeningocele: case report of a 3-year-old child

Myelomeningocele (MMC) is a congenital malformation of the neural tube that occurs in the first weeks of pregnancy. This malformation refers to the caudal non-closure of the neural tube and neural tissue exposure, which lead to neurological problems, such as hydrocephalus, motor disability, genitourinary tract and skeletal abnormalities and mental retardation. Patients with MMC have an acknowledged predisposition to latex allergy and are usually at a high caries risk and activity due to poor oral hygiene, fermentable carbon hydrate-rich diet and prolonged use of sugar-containing medications. This paper addresses the common oral findings in pediatric patients with MMC, discusses the strategies and precautions to deal with these individuals and reports the dental care to a young child diagnosed with this condition.

Effects of the condylar process fracture on facial symmetry in rats submitted to protein undernutrition

PURPOSE: To investigate the facial symmetry of rats submitted to experimental mandibular condyle fracture and with protein undernutrition (8% of protein) by means of cephalometric measurements. METHODS: Forty-five adult Wistar rats were distributed in three groups: fracture group, submitted to condylar fracture with no changes in diet; undernourished fracture group, submitted to hypoproteic diet and condylar fracture; undernourished group, kept until the end of experiment, without condylar fracture. Displaced fractures of the right condyle were induced under general anesthesia. The specimens were submitted to axial radiographic incidence, and cephalometric mensurations were made using a computer system. The values obtained were subjected to statistical analyses among the groups and between the sides in each group. RESULTS: There was significative decrease of the values of serum proteins and albumin in the undernourished fracture group. There was deviation of the median line of the mandible relative to the median line of the maxilla, significative to undernutrition fracture group, as well as asymmetry of the maxilla and mandible, in special in the final period of experiment. CONCLUSION: The mandibular condyle fracture in rats with proteic undernutrition induced an asymmetry of the mandible, also leading to consequences in the maxilla.

Clínica de cães com cardiomiopatia dilatada idiopática, tratados ou não com carvedilol

O tratamento convencionalmente preconizado para cães acometidos pela CMD consiste na prescrição de vasodilatadores, agentes inotrópicos positivos (digitálico), diuréticos, dieta hipossódica e, quando necessário, antiarrítmicos. O carvedilol é um β-bloqueador de 3ª geração, não seletivo, que bloqueia igualmente e competitivamente os receptores (β1, β2 e α1). Produz uma evidente vasodilatação periférica, exerce efeitos anti-oxidantes, removendo radicais livres de oxigênio e prevenindo a peroxidação lipídica nas membranas cardíacas, prevenindo a perda de miócitos e a ocorrência de arritmias e reduzindo a taxa de mortalidade em pacientes humanos. O objetivo do presente estudo foi avaliar clínica, eletrocardiográfica, radiográfica e ecocardiograficamente a evolução de cães com cardiomiopatia dilatada (CMD) tratatos com terapia convencional associada ao carvedilol. Para tal foram avaliados 49 cães com CMD divididos em: grupo NT, tratado com terapia convencional, e grupo T, tratado com terapia convencional associada ao carvedilol. Os animais foram submetidos à avaliação clínica e a exames complementares durante o período de um ano. Os resultados demonstraram que a terapia com carvedilol apresentou boa tolerabilidade na dose de 0,3mg kg-1 12-12horas, aumentou a sobrevida dos cães em 30,9%, não alterou as pressões sistólica e diastólica, reduziu a frequência cardíaca após três semanas de terapia, melhorou significantemente as frações de encurtamento e ejeção após seis meses de tratamento, não promoveu alterações radiográficas e da distância E-septo, diminuiu o índice de letalidade da doença, fato demonstrado pela melhora no escore clínico e na classe funcional dos animais, obtida após três semanas de terapia com carvedilol.
