Chronic Diseases: Chronic Diseases and Development 2 Health, agricultural, and economic effects of adoption of healthy diet recommendations

Transition to diets that are high in saturated fat and sugar has caused a global public health concern as the pattern of food consumption is a mayor modifiable risk factor for chronic non-communicable diseases Although agri food systems are intimately associated with this transition, agriculture and health sectors are largely disconnected in their priorities policy, and analysis with neither side considering the complex inter relation between agri trade patterns of food consumption health, and development We show the importance of connection of these perspectives through estimation of the effect of adopting a healthy diet on population health, agricultural production trade the economy and livelihoods, with a computable general equilibrium approach on the basis of case studies from the UK and Brazil we suggest that benefits of a healthy diet policy will vary substantially between different populations, not only because of population dietary intake but also because of agricultural production trade and other economic factors

Physical-chemical analysis of the cerebrospinal fluid of healthy dogs submitted to different storage periods and temperatures

Disfunções envolvendo o sistema nervoso são de grande importância na Medicina Veterinária, pois tratam-se de enfermidades de elevada incidência e com poucos subsídios auxiliares no seu diagnóstico, prognóstico e na avaliação de terapias empregadas. Ainda hoje, o diagnóstico baseia-se, em grande parte, no histórico e no exame clínico neurológico. Dessa forma, a análise dos constituintes do fluido cefalorraquidiano torna-se uma das poucas alternativas de acesso clínico ao sistema nervoso central (SNC). Mesmo com a grande utilidade do exame físico-químico e citoscópico do liquor na neurologia veterinária, poucos são os estudos sobre a estabilidade dos seus constituintes sob estocagem. Dessa forma, o presente trabalho teve como finalidade verificar a influência da temperatura e do tempo de conservação nas características físico-químicas do liquor de cães hígidos. Para tanto, foram coletadas amostras de LCR, através da punção da cisterna cerebelo-medular de cães clinicamente sadios, as quais foram submetidas à análise da densidade específica, do pH, da glicorraquia, das proteínas totais e das atividades das enzimas creatina quinase (CK) e aspartato aminotransferase (AST), após conservá-las em diferentes temperaturas (25°C, 4°C e -4°C) e por diferentes períodos de tempo (logo após a colheita, 24 horas, 48 horas, uma semana e um mês). Dentre os resultados obtidos, foi possível verificar, principalmente, que houve estabilidade dos parâmetros estudados por até um mês de estocagem nas amostras mantidas sob a temperaturas de congelamento de -4°C.

Hematological profile of healthy Pantaneiro horses

Determinaram-se os valores do hemograma de 187 eqüinos sadios da raça Pantaneira. Para a composição de seis grupos experimentais consideraram-se a faixa etária e o sexo. Verificaram-se 6,2± 1,2 a 8,9± 2,3 hemácias/µl (x10(6)), 32,0± 4,0 a 37,0± 2,8% de volume globular (VG), 11,5± 1,0 a 12,8± 1,6g de teor de hemoglobina/dl, 11,0± 3,2 a 17,0± 2,8 leucócitos/µl (x 10³), 4,9± 1,8 a 7,5± 1,5 neutrófilos segmentados/µl (x 10³) e 5,2± 2,0 a 8,6± 2,0 linfócitos/µl (x 10³). Observaram-se valores mais baixos na contagem de hemácias, e VG e valores mais altos do volume globular médio (VGM) em cavalos castrados (acima de 25 meses de idade). As contagens de leucócitos e neutrófilos segmentados em potros com até oito meses de idade apresentaram valores mais elevados que os encontrados em animais acima dos 25 meses de idade. Constatou-se que não houve influência do sexo nos parâmetros analisados.

Effects of isoflurane on echocardiographic parameters in healthy dogs

Obejective To study the echocardiographic effects of isoflurane at an end-tidal concentration approximating 1.0 times the minimum alveolar concentration (MAC) in healthy unpremedicated dogs.Study design Prospective experimental trial.Animals Sixteen mature mongrel dogs of either sex weighing 11.06 +/- 2.72 kg.Methods After performing a baseline echocardiogram in the awake animal, anesthesia was induced with increasing inspired concentrations of isoflurane via a face mask until tracheal intubation was possible. Following intubation, the end-tidal concentration was decreased to 1.4% for the rest of the anesthetic period. Serial echocardiograms were recorded at 25, 40, and 55 minutes after the end-tidal concentration was reached.Results No changes were observed in heart rate. However, significant decreases were seen in left ventricular end-diastolic diameter (Mean maximal change: 13.8%), interventricular septal thickness during systole (15.2%), interventricular septal thickening fraction (72.2%), left ventricular free wall thickening fraction (63.5%), ejection fraction (39.9%), and fractional shortening (46.7%). In addition, peak flow velocities across mitral, pulmonic, and aortic valves were significantly lower than baseline values. Decreases were also observed in end-diastolic left ventricular volume index (approximately 32.1% from the awake value), stroke index (58.2%), and cardiac index (55.3%) when compared with awake measurements.Conclusions Our results indicate that 1 x MAC isoflurane caused significant myocardial depression in healthy dogs. These changes in myocardial function need to be considered carefully when isoflurane is to be used in dogs with poor cardiovascular reserve.

Serum magnesium levels in healthy dogs submitted to the administration of cisplatin with fluid therapy

Cisplatin is an antineoplastic drug that is used to treat carcinomas and osteosarcomas in dogs. However, it can cause kidney damage which in turn leads to the loss of electrolytes. Concentration of magnesium was evaluated in the blood serum of eight dogs that had undergone therapy with cisplatin. The dogs were divided into two groups. Group 1 was supply with cisplatin (70 mg/m(2), iv) and to prevent nephrotoxcity, saline solution at 0.9% was administered (25 ml/kg/hour, iv in three hours). The animals in Group 2 were not supplied with cisplatin. There was no significant difference (P < 0.05) between the two groups and the results obtained indicated that the protocol used for Group 1 did not cause changes in the serum concentrations of magnesium. Therefore, it can be concluded that the administration of cisplatin does not cause variations if it is combined with the fluid therapy.

Susceptibility of fruits of the 'Valência' and 'Natal' sweet orange varieties to Guignardia citricarpa and the influence of the coexistence of healthy and symptomatic fruits

Em pomar de laranjeiras 'Valência' e 'Natal' avaliou-se a importância da presença de frutos sintomáticos da mancha preta citros (MPC) na severidade da doença nos frutos cítricos da safra subseqüente. Adicionalmente, avaliou-se o estádio de suscetibilidade dos frutos dessas variedades. Frutos foram protegidos com sacos de papel cristal a partir do estádio de 75% de pétalas caídas em outubro de 2000, até abril de 2001. Frutos foram expostos, em intervalos semanais, da 1ª à 24ª semana. Esse processo se deu tanto em plantas onde os frutos da safra remanescente foram previamente colhidos, como naquelas cujos frutos sintomáticos da safra remanescente permaneceram até a sua queda natural. Avaliou-se a severidade da doença usando uma escala de notas que variou de 0 (ausência de sintomas) a 6 (sintomas severos). Observou-se que para as duas variedades os conídios de Phyllosticta citricarpa, formados nas lesões dos frutos da safra remanescente, não provocaram incremento significativo na severidade da doença dos frutos da safra subseqüente. A proteção dos frutos até 10ª semana após a queda de pétalas não influenciou na quantidade final de lesões, indicando que as descargas de ascósporos que ocorreram a partir desse momento foram, provavelmente, responsáveis pela severidade da doença. Frutos que ficaram expostos entre a 20ª a 24ª semanas após a queda de 75% de pétalas mostraram-se sintomáticos, indicando que nesse estádio frutos encontravam-se suscetíveis ao patógeno.

Evaluation of the hemogram in healthy canines under cisplatin therapy

Objective. To evaluate the average values of the hemogram test in healthy dogs during chemotherapy with cisplatin. Materials and methods. The hemogram parameters of eight healthy canines, which underwent therapy with cisplatin, were evaluated. These canines were divided into two groups. The dogs in the first group were given cisplatin (70mg/m(2), i.v.) and to prevent kidney poisoning they were given physiological serum at 0.9% (25mL/kg/h, i.v.). The dogs in group two were not given cisplatin. Results. The hemogram of the dogs in the first group did not show any significant difference (p>0.05) as compared to the dogs in group 2.Conclusions. The data obtained indicate the protocol used with cisplatine does not significantly alter the average values of the hemogram test and the number of chemotherapy sessions increases the risk of diminishing the values of the hemogram test.

Effects of two proprioceptive neuromuscular facilitation techniques in different planes on hamstrings muscles of healthy subjects

Introduction: The proprioceptive neuromuscular facilitation technique (PNF) has been proven to be efficient, since it was found higher gain of joint range-of-motion compared to the classic stretching. This study aimed to perform a comparison between the muscular stretching techniques and the PNF hold-relax on the internal and external sagittal/diagonal plane.Method: Randomly divided in 3 groups by a drawing, 30 healthy male individuals have undergone the test. In group I the hold-relax technique was utilized on the sagittal plane, grupo II receveid hold-relax on the internal and external diagonals, and group III, on which an evaluation was performed, worked as control. All the groups went through tests on the first, fifth and fifteenth day after the application of the different approaches. In this evaluation it was used a Flexis (R) Fleximeter.Result: Group II (diagonal) obtained statistically significant gain of 13.99% in the immediate post-test and post test later obtained a loss of 4.81%, group I (sagittal) showed no statistical difference as the group III (control).Conclusion: We conclude that the technique of PNF in the diagonal plane is effective in the flexibility of the hamstring muscles.

Evaluation of the adverse effects of oral firocoxib in healthy dogs

This study evaluated the adverse effects of oral firocoxib in dogs. Six dogs (20.2 +/- 6.3 kg) were studied. Values for complete blood count (CBC), serum urea, creatinine, alanine transaminase, alanine phosphatase, -glutamyl transferase, occult blood in feces, platelet aggregation, and buccal mucosal bleeding time were measured before and 7, 14, 21, and 29 days after SID treatment with firocoxib 5.3 +/- 0.34 mg/kg (FG) or lactose 1 mg/kg (LG) for 2 8 days, in a randomized crossover study. Gastrointestinal (GI) tract endoscopy was performed before treatment began and at 29 days. Lesions were scored from grade 0 to 6. Data were analyzed using ANOVA and paired t-tests (P < 0.05). None of the dogs presented adverse clinical effects. There were no significant changes in CBC, biochemical profiles within groups, or differences between groups. Pretreatment mean SD bleeding time (LG, 70.7 +/- 32.1 sec; FG, 75.8 +/- 38.1 sec) and platelet aggregation (LG, 86.4 +/- 10.2%; FG, 85.6 +/- 9.2%) were not significantly different from readings at 29 days (LG, 95.2 +/- 25 sec; FG, 91.7 +/- 24 sec and LG, 73.2 +/- 15.1%; FG, 84 +/- 10.3%) nor the groups were different. None of the dogs had positive fecal occult blood tests, and endoscopic lesion scores were grade 0 both before treatment and at 29 days. Administration of firocoxib did not cause any adverse effects on GI, or hematological or serum biochemical variables and appears to have been well tolerated by dogs.
