Effects of hyperprotein diet on anxiety, haemodynamics and morphofunctional aspects of the heart of Wistar rats.

NEW FINDINGS: What is the central question of this study? The consumption of a high-protein diet has been associated with an anxiogenic factor that can influence anxiety and possible cardiovascular changes: does the consumption of a high-protein diet interfere with anxiety, haemodynamics and morphofunctional aspects of the heart of Wistar rats? What is the main finding and its importance? Our study showed that the high-protein diet did not interfere with anxiety and haemodynamics. The animals in the hyperproteic group showed positive heart adaptations characterized by less work and lower heart rate without impairing ejection fraction and systemic blood pressure. ABSTRACT: Anxiety is a mechanism preparatory to a response in situations of threat and danger, involving behavioural, affective and physiological factors. Protein-based foods have a high concentration of amino acids which perform multiple functions, including in the biosynthesis of excitatory transmitters for the central nervous system. In recent years, adherence to high-protein diets has been gaining ground in society, on the basis that it brings benefits to the musculoskeletal system and cardiovascular health. The aim of the present study was to investigate the effect of a high-protein diet in a state of anxiety and to investigate morphofunctional cardiovascular effects of a high-protein diet in Wistar rats. The experiment lasted 8 weeks and two groups of male rats were submitted to either a normoproteic or a hyperproteic diet. Anxiety was assessed using the plus maze test and cardiovascular morphofunctional aspects using transthoracic echocardiography and invasive measurements of femoral blood pressure. There was no statistically significant difference in the anxiety test, but the hyperproteic group was more agitated, with greater displacement during the test. Changes were found in systolic and end-diastolic volume, left ventricular diameter in systole and heart rate, which were significantly lower in the hyperproteic group, and there was an increase in the thickness of the interventricular septum in diastole. The results showed no influence of the higher protein diet on the animals' anxiety, body weight and haemodynamics.

Assistência a crianças com atraso neuromotor: perfil epidemiológico e experiência interdisciplinar / Assistance to children with neuromotor delay: epidemiologic profile and interdisciplinary experience

O atendimento ao paciente pediátrico com atraso no desenvolvimento neuromotor (ADNM), em particular aqueles com diagnóstico de paralisia cerebral (PC), é um grande desafio para os serviços públicos de saúde em todo o mundo. A complexidade do manejo clínico torna relevante uma abordagem integrada e interdisciplinar. O objetivo deste estudo foi conhecer o perfil epidemiológico e as principais comorbidades dos pacientes com ADNM, particularmente com PC, atendidos em um serviço interdisciplinar de referência com 10 anos de experiência no manejo desses pacientes. Estudo transversal descritivo e retrospectivo por meio de análise de prontuários dos pacientes do Ambulatório de Pacientes Especiais do Hospital de Clínicas de Uberlândia no período de 2010 a 2012. Foram analisados 136 prontuários, 79 (58,1%) do sexo masculino e 70 (51,5%) procedentes de Uberlândia. O diagnóstico frequente foi PC 113 (83,1%). A obstipação intestinal (OI) e a doença do refluxo gastroesofágico (DRGE) foram as comorbidades mais frequentes, respectivamente, 85 (62,5%) e 80 (58,8%). Alimentação por via alternativa foi observada em 71 (52,2%), sendo 61 (44,8%) por gastrostomia e 10 (7,3%) por sonda nasoenteral. Doenças respiratórias ocorreram em 59 (43,3%) pacientes e foram responsáveis por internação em 22 (16,1%); 98 (72,0%) pacientes realizavam fisioterapia, 62 (45,6%) fonoterapia e 46 (33,8%) terapia ocupacional. Acompanhamento odontológico foi observadoem 49 (36,0%) deles. O reconhecimento do perfil epidemiológico, comorbidades e complicações mais prevalentes auxiliam a equipe interdisciplinar especializada a desenvolver estratégias para melhor assistência e cuidados aos pacientes com ADNM.

Care rendered to pediatric patients with neuromotor delay, particularly those diagnosed with Cerebral Palsy (CP), is a major challenge to public health services worldwide. The complexity of clinical management makes an integrated and multidisciplinary approach relevant. The aim of this study was to get to know the epidemiological profile and the main co- morbidities of patients with neuromotor delay, who are attended in a multidisciplinary referral service which has 10 years experience in the management of these patients. This study was carried out through cross descriptive and retrospective analysis of medical records of patients at the Special Patient Clinic at the University Hospital of Uberlândia, during the period of 2010-2012. One hundred and thirty six (136) records were analyzed, 79 (58.1%) were male and 70 (51.5 %) coming of Uberlândia. The more frequent diagnosis is CP in 113 (83.1%) Intestinal Constipation (IC) and gastro-esophageal reflux disease (GERD) were the most frequent co-morbidities, 85 (62.5%) and 80 (58.8%) respectively. Feeding by way of alternative means was observed in 71 (52.2%), with 61 (44.8%) gastrostomy and 10 (7.3%) through a nasogastric tube. Respiratory disorders occurred in 59 (43.3%) patients and were responsible for hospitalization in 22 (16.1%) cases. 98 (72.0%) patients underwent physical therapy, 62 (45.6%) speech therapy and 46 (33.8%) occupational therapy. Dental care was observed in 49 (36.0%) patients. Recognition of the epidemiological profile, comorbidities and more prevalent complications assist the specialized interdisciplinary team in developing strategies to best support and care for patients with neuromotor delay
