Efeitos da parede de levedura em dieta úmida na microbiota fecal, na produção de gás e na morfologia intestinal de gatos adultos

The aim of this study is to evaluate the effects of yeast extract (EPL) in the moist diet on the fecal microbiotal, gas production and intestinal morphology of adult cats. Twenty adult cats from both sexes were randomly assigned to four treatments: 1) moist commercial diet (control); 2) control + 0,2% yeast extract dry matter; 3) control + 0,4%; and 4) control + 0,6%. Fecal microbiology and intestinal morphology were performed by radiographic, ultrasound, colonoscopy and intestinal biopsy exams for histology. There were no significant differences (P>0,05) for lactic acid bacteria counts and clostridium-reductor, gas area in the bowel (radiographic), wall thickness of the colon (ultrasound) and colonocytes count/globet cells (histology). Through colonoscopy, changes in characteristics of the intestinal mucosa in animals receiving treatment 4 were noticed. It is concluded that the addition of up to 0.6% EPL had no effect on the parameters evaluated, but further studies are needed to understand the action mechanisms and additive effects for domestic cats.

Effect of concurrent training on risk factors and hepatic steatosis in obese adolescents

OBJETIVOAnalisar os efeitos de 20 semanas de treinamento concorrente sobre as variáveis de composição corporal, perfil lipídico e diagnóstico da esteatose hepática em adolescentes obesos.MÉTODOSRealizou-se um ensaio clínico aberto com 34 adolescentes obesos com idades entre 12 e 15 anos. Foram analisados gordura corporal total e de tronco, colesterol total e suas frações (HDL, LDL e VLDL) e triglicérides, sendo realizado exame de ultrassonografia de abdome superior para diagnosticar esteatose hepática. Os participantes foram submetidos ao treinamento concorrente (associação de treino com pesos e exercício aeróbio) três vezes por semana, com duração de uma hora-aula durante 20 semanas. Para o tratamento estatístico, foram realizados o teste t de Student pareado e a análise de frequência, a fim de verificar as reduções relativa e absoluta do diagnóstico da esteatose hepática, adotando-se p<0,05.RESULTADOSOs adolescentes estudados apresentaram melhoras significativas da composição corporal, com diminuição do percentual de gordura total, da massa gorda total, da gordura de tronco e do aumento da massa magra, além de redução do tamanho dos lóbulos do fígado, dos índices de prevalência da esteatose hepática, do colesterol total e LDL-colesterol.CONCLUSÕESO treinamento concorrente foi efetivo por promover melhorias significativas de variáveis da composição corporal e do perfil lipídico, além de reduzir a prevalência da esteatose hepática.

Recanalization after acute deep vein thrombosis

O processo de recanalização das veias dos membros inferiores, após um episódio de trombose venosa profunda aguda em pacientes anticoagulados com heparina e inibidores da vitamina K, faz parte da evolução natural da remodelagem do trombo venoso. Esse complexo processo de remodelagem envolve a adesão do trombo à parede da veia, à resposta inflamatória da parede do vaso, levando à organização e subsequente contração do trombo, à neovascularização e à lise espontânea de áreas no interior do trombo. A presença de fluxo arterial espontâneo em veias com trombose recanalizada tem sido descrita como secundária à neovascularização e se caracteriza pelo desenvolvimento de fluxo com padrão de fístulas arteriovenosas, identificadas por meio de mapeamento dúplex colorido. Nesta revisão, são discutidos alguns aspectos controversos da história natural da trombose venosa profunda, para uma melhor compreensão da sua evolução e do seu impacto sobre a doença venosa.

Does hyperglycemia in pregnancy change fetal kidney growth?: a longitudinal prospective study

PURPOSE: To measure fetal renal volume in normoglycemic and hyperglycemic pregnancies. METHODS: A longitudinal prospective study was conducted and included 92 hyperglycemic and 339 normoglycemic pregnant women attended at the prenatal service of a hospital from Rio de Janeiro State. Ultrasound examinations were performed to estimate gestational age at baseline and the kidney volume was estimated using the prolate ellipsoid volume equation. RESULTS: Fetal kidney volume growth between normoglycemic and hyperglycemic pregnancies are significantly different. The fetal kidney volume growth in pregnancy is positively correlated with gestational age explained by these predictor equations, by group: normal renal volume = exp (6.186+0.09×gestational week); hyperglycemic renal volume = exp (6.978+0.071×gestational week) and an excessive growth pattern for hyperglycemic pregnancies may be established according to gestational age. CONCLUSION: This is important for early detection of abnormalities in pregnancy, particularly in diabetic mothers.

Casuística dos exames de diagnóstico por imagem na medicina de animais selvagens - 2009 a 2010

The aim of this study was to retrospectively evaluate in the casuistry on class and systems frequently diagnosed in wild animals that were sent to the FMVZ-UNESP-Botucatu diagnostic imaging service. The class of birds was the most referred to the centers, followed by the mammals and reptiles. The majority of the requested tests were the radiographs and in a minor scale the tomography and ultrasound. Although the birds were the greatest number of animals sent to the service, mammals were the most radiographed for wound control. The most frequently observed system was the musculoskeletal caused by trauma, especially in birds. The radiograph was the most exam initially indicated, then the animal could be forwarded to other imaging modalities, which in wild animals medicine is still limited to research.

Comparação das características e medidas ultrassonográficas das glândulas adrenais de cães e gatos filhotes saudáveis

The aim of the study was to analyze and compare the ultrasound characteristics of adrenal glands between healthy puppies and kittens by establishing standards of normality and references. Fifteen healthy crossbred puppies with mean weight of 3 kg and fifteen healthy crossbred kittens with mean weight of 2 kg, aged between five and six months, participated in the study. The animals were submitted to ultrasound exam of adrenal glands for visualization of their internal characteristics. The frequency of visualization of adrenal glands was 100% in kittens. In puppies the frequency was 75% for the right gland and 100% for the left gland. The puppy's adrenal gland, both right and left, were bigger in length (1.08 ± 0.01 cm, 1.11 ± 0.01 cm) and width (0.42 ± 0.02 cm, 0.45 ± 0.01 cm) in relation to kittens' adrenal gland length (0.64 ± 0.01 cm, 0.63 ± 0.01 cm) and width (0.30 ± 0.02 cm, 0.34 ± 0.01 cm). The adrenal gland of puppies and kittens was hypoechogenic to the surrounded fat, delimited by a hyperechogenic line and without distinction of the cortical and medullar region. The ultrasound dimensions of length and width of the adrenal glands, both right and left, were the same in puppies and kittens. The right and left puppies' adrenal glands were longer and wider than the kittens' glands.

Variação da ecogenicidade difusa em parênquima hepático homogêneo relacionada aos achados bioquímicos e hematológicos em cães

The present study evaluated the liver with homogeneous parenchyma in dogs, with diffuse reduced echogenicity (G1), increased echogenicity (G2) and normal echogenicity (G3) by ultrasound examination associating the findings on animal profile, liver size and hematology and biochemistry results. Blood samples obtained by cephalic or jugular venipunture were submitted for hemogram and ALT, ALP, total proteins, albumin, globulin, urea and creatinine analysis. Among the 30 dogs in G1, 30 (100%) presented portal venous and gall bladder wall clarity, 23 (76.67%) presented normal liver size and edges, 15 (50%) were from 1 to 6 years old and 8 (26.67%) belonged to the lhasa apso breed. No predispositions were found according to gender, as well as no significant alterations in biochemical and hematological exams were observed in G1. The most prevalent disease found in this group was gastroenteritis (43.33%). Among the 30 dogs in G2, 27 (90%) presented hepatomegaly and rounded hepatic edges, 18 (60%) were over 9 years old, 16 (53.33%) were female and 9 (30%) belonged to the poodle breed. The laboratorial findings related to this group were increased ALT and ALP serum activity, decreased levels of total protein, albumin, globulin, erythrocytes and hematocrit, as well as leukocytosis with neutrophilia and a left shift, eosinopenia, lymphopenia and monocytosis. The most prevalent diseases found in this group were metabolic disorders (54%), such as diabetes mellitus and hyperadrenocorticism, and chronic hepatopathies (17%) due to prolonged and continuous use of corticoid and anticonvulsive drugs. Among the 30 dogs in the control group (G3), normal liver size and edges were presented in 22 (73.33%). In this group, no alterations were seen in laboratorial exams.

Influência de abordagens biopsicossociais e autocuidados no controle das disfunções temporomandibulares crônicas

BACKGROUND AND OBJECTIVES: Temporomandibular joint disorder (TMD), which is a musculoskeletal condition of the masticatory system, may become chronic and further worsen quality of life (QL) of patients. Due to the inter-relationship between physical and emotional symptoms, there is an increasing search for the integrative model, which includes psychosocial approaches for the treatment of painful conditions. This study aimed at reviewing in the literature the impact of education and simple self-care modalities on pain and disorders related to chronic painful TMD. CONTENTS: Psychosocial factors are often involved with pain chronicity, making bio-behavioral approaches increasingly more indicated to change pain perception and to decrease distress and psychosocial changes which go along with persistent pain. CONCLUSION: Current literature, although not extensive, indicates positive results of education and self-care methods for chronic painful TMD. Further studies are needed to reinforce such findings and spread the application of such approaches to control chronic and TMD pain.

Echobiometrics kidney and renal artery triplex doppler of canine fetuses

O objetivo deste estudo foi avaliar, por meio da ultrassonografia convencional modo B, as características sonográficas e a biometria dos rins de fetos caninos, bem como determinar os índices vasculares da artéria renal dos conceptos ao Doppler Triplex. Foram utilizadas 24 fêmeas Shi-tzu e Pugs pesando de quatro a 10 kg e com idade entre quatro e seis anos. Ao modo B, a ecobiometria renal fetal, a regularidade da superfície renal, a ecotextura e a relação córtico-medular foram avaliadas durante a quinta, sexta, sétima e oitava semanas gestacionais. Ao Doppler Triplex, durante o mesmo período em que se realizou o exame convencional, foram determinados o pico de velocidade sistólica (PVS), a velocidade diastólica final (EDV) e o índice de resistência vascular (RI) e de pulsatividade (PI). Ao modo B, não foram detectadas alterações em rins fetais, e à ecobiometria renal dos fetos, foi possível determinar medidas renais importantes, verificando-se aumento das biometrias no decorrer do desenvolvimento fetal (P<0,0001). Ao Doppler Triplex, determinaram-se os índices vasculares da artéria renal fetal, sendo que os valores para PSV e EDV aumentaram no decorrer das semanas gestacionais (P<0,05) e permaneceram constantes para PI e RI (P>0,05). Concluiu-se que o modo B e o Doppler Triplex são ferramentas importantes para a avaliação do desenvolvimento renal fetal, com a utilização da ecobiometria renal e avaliação dos indices vasculares da artéria renal de fetos caninos.

Avaliação ultrassonográfica dos efeitos da acupuntura na involução uterina em cadelas

The aim of this study was to evaluate, by means of ultrasound exam, acupuncture effects on uterine involution during the postpartum period in bitches with electroacupuncture. The phenomenon of eutocic uterine involution was studied in 16 bitches, randomly divided into two groups of eight animals each. Group 1 (G1) was treated with electric stimulation (electroacupuncture) of the needle at the points SP6, L3, Bai Hui, TB1, B23, B26, and group 2 (G2), the control group, received treatment in Sham points (placebo points), also with electrical stimuli. The monitoring of the phenomenon of uterine involution was performed by ultrasonography on days 0 (partum), 1, 3, 7 and 14 postpartum. We used SAS statistical analysis method, in order to compare the groups. The results of ultrasound examinations (mean and standard deviations in cm) for the period of observation were as follows: G1: 0.30 ± 0.01 (P), 2.08 ± 0.21 (LU), 4.13 ± 0.23 (DU) and G2: 0.31 ± 0.01 (P) 1.82 ± 0.09 (LU), 3.92 ± 0.11 (DU). We concluded that electroacupuncture affected uterine tone (lasting and uniform at the end of treatment). Electroacupuncture produces a positive tone in the uterus, aiding at the prevention of puerperal diseases.
