Introduction: The lack of physical exercises generated by immobilization of the lower limbs leads to changes in body composition that are generally associated with the imbalance of metabolic rate coupled with a sedentary status, which can result in obesity, diabetes mellitus and cardiovascular disease. Therefore, the improvement of physical fitness can contribute to promoting health and quality of life for these patients. As there is a very small number of research in this direction, our purpose was to investigate the effects of an adapted swimming program in protocol interval, for people with spinal cord injury, aiming to verify the improvement of your fitness and, consequently, some biochemical variables important for health. Methodology: The study included 17 subjects with spinal cord injury, sedentary, divided into two groups: 11 participants in the training group (TG) and 6 in control group (CG). TG was applied by a protocol of interval training in swimming for eight consecutive weeks, three times a week. The protocol employed a stroke of breaststroke in work periods of moderate to severe, and stroke in the backstroke, in periods of active recovery. The CG has not participated in any physical activity. Both groups were collecting blood for biochemical analysis, before (evaluation) and after (revaluation) the swimming program. Results and Discussion: The concentrations of triglycerides, total cholesterol and LDL-cholesterol showed no significant changes in assessment for reassessment in both groups. However the TG, the level of HDL-cholesterol were significant differences (p=0,0110), showing an improvement in posttraining, which did not occur in the CG. With respect to the state of fitness, the results revealed a significant difference in relation to time and distance covered in water when compared with the pre-training (p<0,001), showing a great improvement in the ability to shift with the stroke of breaststroke and a significant improvement in cardiorespiratory function. Conclusion: The swimming program interval used, with moderate to severe intensity, can even in a short period of time, promote positive changes in HDLcholesterol in individuals with spinal cord injury studied, and substantially improve your fitness.

A Pseudomonas aeruginosa aparece como um patógeno oportunista na fibrose cística, sendo a maior fonte de infecção pulmonar e é responsável por altas taxas de mortalidade nestes pacientes. O objetivo deste trabalho é de mostrar as características espirométricas e clínicas dos pacientes com fibrose cística atendidos no Hospital Universitário João de Barros Barreto (HUJBB), no Pará. Foi realizado um estudo retrospectivo nos prontuários de 44 pacientes acompanhados no HUJBB, no período de 1997-2007, que atenderam aos critérios de inclusão, sendo 14 colonizados por P. aeruginosa, com a ocorrência de 9 óbitos. Com nível de significância de 5%. No grupo colonizado 10 eram do sexo feminino, a idade média dos sintomas iniciais foi de 0.3±0.6 anos, com diferença significativa quando comparado com pacientes não colonizados (p<0.05). A idade média ao diagnóstico foi de 13.1±10.8 nos colonizados todos apresentavam sintomas respiratórios persistentes ao diagnóstico. A média dos valores percentuais preditos das espirometrias, referentes à avaliação inicial e final, do grupo colonizado foi VEF1(60.0± 25.0%) e (47,82±16.1%) e FEF25-75%(42.5± 22.9%) e (26,5±17.9%) e no grupo não colonizado foi VEF1(79.2± 21.0%) e (79,6±18.0%) e FEF25-75%(69.2± 26.7%) e (68,9±26.8%), respectivamente (p<0.005). A média do escore de Shwachman inicial nos colonizados foi de 42.9±13.5 e nos não colonizados foi de 68.4±15.1(p<0.0001) e na avaliação final foi de 36.6±18.7 e 73.6±12.3 (p<0.0001), respectivamente, com diferença significativa entre os grupos. Os fatores relacionados aos óbitos encontrados foram a colonização por P. aeruginosa, estado nutricional deficiente e VEF1 reduzido. Na casuística estudada foi encontrado maior comprometimento da função pulmonar e idade média mais elevada ao diagnóstico do que em outros estados brasileiros. Estes dados reforçam a necessidade de ações para um diagnóstico precoce no estado do Pará, propiciando uma abordagem terapêutica eficaz e direcionada, buscando aumento de sobrevida e melhoria da qualidade de vida destes indivíduos, objetivo principal das ações dos profissionais envolvidos nesta assistência.

Ivabradine (IVB) is a heart rate lowering agent that acts via selective inhibition of the pacemaker funny current in sinoatrial nodal P cells, thus, reducing heart rate at rest and during exercise with minimal effect on myocardial contractility, blood pressure, and intracardiac conduction. IVB exerts no effect on external respiratory function parameters and it may also play a role in patients with concurrent chronic obstructive pulmonary disease. This property constitutes an important advantage over β-blockers. IVB acts by reducing the heart rate in a mechanism different from β-blockers, calcium channel blockers or late sodium channel blockers, three commonly prescribed antianginal drugs. As clinical trials have shown, it is remarkably well-tolerated and offers an alternative for patients who cannot take β-blockers. The combination of IVB and atenolol at commonly used doses in patients with chronic stable angina produced additional efficacy with no untoward effect on safety or tolerability. Additionally, side effects are rare and largely limited to a luminous phenomenon or phosphenes. This sensation is thought to be due to a block of Ih in the retina, a current very similar to cardiac If channels. IVB is contraindicated in patients with sick sinus syndrome or sinus node dysfunction and in patients taking hepatic inhibitors of Cytochrome P450 family 3, subfamily A, polypeptide 4 (abbreviated CYP3A4), with exception of omeprazole or lansoprazole. This review briefly summarizes the main studies regarding this drug.

The thyroid gland was assessed by ultrasound in healthy euthyroid mixed-breed medium size dogs in different age groups. The objective was to verify ultrasonographic imaging patterns in these groups, as well as to identify possible changes in imaging features resulting from ageing. Thirty dogs - 10 young (<1 year), 10 adult and 10 elderly - without clinical signs or history of thyroid gland disease with complete blood count and thyroid function tests within the reference values were evaluated. Each thyroid lobe was examined by ultrasound for shape, size, echogenicity and echotexture. The analysis of echogenicity and echotexture was made by histogram. Thyroid volume was estimated by the equation for ellipsoid (length x width x height) pi/6. The thyroid volume of the young dogs in this study had a tendency to be higher than in adult dogs (P = 0.068) and older dogs (P = 0.120). The height of the thyroid lobe in the longitudinal plane was significantly higher (P = 0.026) in young dogs compared with the other dogs. The echotexture and echogenicity had no significant differences between groups, but the echogenicity was greater in older dogs. The results point out that ultrasound imaging of the thyroid volume is influenced by age in euthyroid dogs.

Hypothyroidism is a common endocrine disorder in dogs caused by insufficient production and secretion of thyroid hormones. Most affected dogs have primary hypothyroidism that results from lymphocytic thyroiditis, idiopathic thyroid atrophy, or more rarely, neoplastic destruction. Secondary hypothyroidism resulting from inadequate secretion of thyrotropin (thyroid-stimulating hormone –TSH) from the pituitary gland is less commonly recognized. Tertiary hypothyroidism resulting from a deficiency of hypothalamic thyrotropin-releasing hormone (TRH) has not been documented in dogs. The diagnosis of hypothyroidism in dogs is made on the basis of clinical findings, results of routine laboratory and thyroid gland function tests and response to thyroid hormone replacement. Unfortunately, these tests have high sensitivity, but low specificity, for use in the diagnosis of hypothyroidism. Thyroid hormone supplementation is indicated for the treatment of confirmed hypothyroidism and for the diagnoses of the disease through clinical response to trial therapy

Introdução: A lesão mais comumente encontrada na população ativa é a entorse de tornozelo. Cerca de 40% destes casos continuam a manifestar sensação de instabilidade articular mesmo após a fase aguda da lesão, caracterizando a instabilidade funcional do tornozelo (IFT). A IFT está relacionada com déficits proprioceptivos e redução na capacidade de produção de força e potência muscular. Haja vista que o basquetebol é um esporte com grande incidência de lesões no tornozelo faz-se necessário o entendimento de métodos de avaliação de baixo custo, que possam contribuir para a prevenção deste tipo de lesão em atletas. Objetivo: Nesse sentido, o presente estudo, tem como objetivo identificar os parâmetros de torque, atividade eletromiográfica, senso de reposicionamento articular e a pontuação em teste funcional em jogadoras de basquetebol com tornozelo estável. Correlacionar os valores de torque, atividade eletromiográfica e do senso de reposionamento articular com a pontuação dos testes funcionais em individuos saudáveis. Método: Participaram deste estudo 6 atletas do gênero feminino praticantes do basquetebol com idade entre 18 e 25 anos. As voluntárias realizaram os seguintes testes: torque isocinético concêntrico em inversão (INV) e eversão (EVE) nas velocidades de 60º e 120º, cinco testes funcionais e teste de reposicionamento articular com os ângulos-alvo de 10º e 20º de inversão. Após a verificação da normalidade de distribuição dos dados com o teste Shapiro-Wilk, utilizou-se o teste de Correlação Spearman para verificar a correlação dos testes funcionais com o pico de torque, o sinal EMG e o reposicionamento articular. Resultados: Não foi encontrados resultados esperados no estudo, exceto na correlação negativa para os valores de RMS do TA na velocidade de 120º nas contrações isocinética...(Resumo completo, clicar acesso eletrônico abaixo)

Background. Prospective studies evaluating the risk of hepatitis B virus (HBV) transmission in transplants of kidneys from hepatitis B core antibody (anti-HBc)-positive/ hepatitis B surface antibody (anti-HBs) negative donors are still lacking. The objective of this study was to assess the safety of kidney transplantation with the use of anti-HBc positive donors.Methods. This prospective case series study included 50 kidney transplant recipients from anti-HBc positive donors with or without anti-HBs positivity. Recipients were required to test positive for anti-HBs (titers >10 mUI/mL), regardless of anti-HBc status, and negative for hepatitis B surface antigen (HBsAg). Recipient and donor data were retrieved from medical records, databases, and organ procurement organization sheets. Liver function tests were performed at progressively increasing post-transplantation intervals. Complete serologic tests for HBV were performed before transplantation, 3 and 6 months after transplantation, and annually thereafter.Results. Six months after transplantation, all recipients were negative for HBsAg, HBeAg, anti-HBe, and anti-HBcIgM. No seroconversion was observed among the 20 patients who received kidneys from anti-HBc positive/anti-HBs negative donors. No patient showed elevated liver enzymes during follow-up.Conclusions. Kidney transplantation using organs from anti-HBeIgG positive donors (even when they are concurrently anti-HBs negative) in anti-HBs positive recipients is a safe procedure and may be considered as a way to expand the donor pool.
