Despite the observation of an increase in life expectancy in individuals with Spinal cord injury (SCI), it is lower than that of the general population. Studies have shown that affected individuals have a sedentary lifestyle that reflects negatively on health and quality of life. Studies have demonstrated that HDL cholesterol (HDL-C) levels, a high-density lipoprotein and important predictor of cardiovascular disease, are lower in this population exposing these people to a greater incidence of heart disease from atherosclerotic process In the general population, exercise increases HDL-C serum levels, but this phenomenon is not very clear in people with spinal cord injury (SCI). The present study examined the effect of both swimming and wheelchair basketball in the lipid profile of eleven men and seven women with SCI. The subjects included in regular exercise programs showed increases in HDL-C levels and decreases in CT/HDL-C and LDL-C/HDL-C ratios. We found better results mainly in men with lower levels of SCI and in those that sustained exercise intensities above 60% of the heart rate reserve. The duration of training sessions can be an essential factor in these results. The results suggest that both the exercise prescription and the personal characteristics of people with SCI influence changes in the lipid profile mediated through exercise. The elaboration of this work is an attempt to clarify uncertainties about health and the longevity of people with SCI generated in discussion of all members of the interdisciplinary rehabilitation team, especially the physiotherapists, nutritionists, nurses and physicians that contributed considerably in all phases of the research

The purpose of this paper was to study patients with congenital and acquired hemiparesis, their clinical aspects, the presence or not of epileptic seizures, and electroencephalographic (EEG) and Magnetic Resonance Imaging (MRI) findings. We analyzed the interrelation between etiology, the presence and seriousness of epileptic seizures (ES) and the possible causes of refractoriness. This is a prospective study using the clinical diagnosis of a child neurologist, who attested to the presence of unilateral motor lesions. We compared the electroencephalographic findings in patients with or without epileptic seizures, and investigated if among the former, these seizures were controlled or not, their likely etiology and risks of refractoriness. EEG background activity on the lesion and contralateral side was analyzed, in addition to the presence of concomitant epileptiform activity. Encephalon MRIs of all the patients were studied to correlate etiology and the control or not of epileptic seizures. The disorganization of bilateral EEG activity correlated with the difficult-to-control epileptic seizures. Suitably organized background activity contralateral to the lesion is a good prognosis in relation to epileptic seizures. Focal epileptogenic activity does not necessarily predispose to epileptic manifestation. The MRI is more important in determining etiology than in prognosing epileptic seizures. This study used a multidisciplinary approach involving child neurologists, a physical therapist and a neuroradiologist. This meets the criteria of multidisciplinarity of the Postgraduate Program in Health Sciences

Stroke represents the first cause of disabilities among adults. Although different professions work together in treatment of stroke patients, all they use different terminologies for the description of the patients problems and it can constitute an impediment in the communication between the staff members. Thus, the multidisciplinary and interdisciplinary work would be facilitated if using a reference common tool, as the new International Classification of Functioning, Disability and Health (ICF). However, the ICF is very extensive and complex and due to its complexity, it has been evidenced the necessity to select its categories to become it more practical. The aim of the study was to investigate which categories of the ICF are more suitable to evaluate and to describe the stroke patient in the view of teachers and municipal public health professionals. It was a descriptive research, which involved 5 professors and 11 professionals of Physiotherapy that have worked at the health public area in Natal / RN. It was used the Delphi Technique in 3 rounds and the Likert Scale to select the categories among the ICF components. As result, from the 362 IFC categories, 94 were selected. The selected categories correspond to rehabilitative characteristics of Stroke patients in the universe of the Physiotherapy performance. The methodology applied was suitable to the studied object emphasizing the necessity of future studies for validation of the chosen categories

Investigate intrahospital and neonatal determinants associated to the weaning of very low birth weight (VLBW) infants. Methods: 119 VLBW (<1500g) infants 81 were monitored from July 2005 through August 2006, from birth to the first ambulatory visit after maternity discharge. This maternity unit uses the Kangaroo Method and the Baby Friendly Hospital Initiative. Results: Out of 119 VLBW infants monitored until discharge, 88 (75%) returned to the facility, 22 (25%) were on exclusive breastfeeding (EB) and 66 (75%) were weaned (partial breastfeeding or formula feeding). Univariate analysis found an association between weaning and lower birth weight, longer stays in the NICU and longer hospitalization times, in addition to more prolonged enteral feeding and birth weight recovery period. Logistic regression showed length of NICU stay as being the main determinant of weaning. Conclusion: The negative repercussion on EB of an extended stay in the NICU is a significant challenge for health professionals to provide more adequate nutrition to VLBW infants

Tityus serrulatus, popularly known as yellow scorpion, is one of the most studied scorpion species in South America and its venom has supplied some highly active molecules. The effects of T. serrulatus venom upon the renal physiology in human showed increased renal parameters, urea and creatinine. However, in perfused rat kidney the effects were not tested until now. Isolated kidneys from Wistar rats, weighing 240-280 g, were perfused with Krebs-Henseleit solution containing 6% (g weight) of previously dialysed bovine serum albumin. The effects of T. serrulatus venom were studied on the perfusion pressure (PP), renal vascular resistance (RVR), urinary flow (UF), glomerular filtration rate (GFR), sodium tubular transport (%TNa+), potassium tubular transport (%TK+) and chloride tubular transport (%TCl-). Tityus serrulatus venom (TsV; 10 mu g/mL) was added to the system 30 min after the beginning of each experiment (n = 6). This 30 min period was used as an internal control. The mesenteric bed was perfused with Krebs solution kept warm at 37 T by a constant flow (4 mL/min), while the variable perfusion pressure was measured by means of a pressure transducer. The direct vascular effects of TsV (10 mu g/mL/min; n=6), infused at a constant rate (0.1 mL/min), were examined and compared to the infusion of the vehicle alone at the same rate. TsV increased PP (PP30'= 127.8 +/- 0.69 vs PP60' = 154.2 +/- 14 mmHg*, *p < 0.05) and RVR (RVR30' = 6.29 +/- 0.25 vs RVR60' = 8.03 +/- 0.82 mmHg/mL g(-1) min(-1)*, *p < 0.05), decreased GFR (GFR(30') =0.58 +/- 0.02 vs GFR(60') = 0.46 +/- 0.01 mL g(-1) min(-1)*, *p < 0.05) and UF (UF30' = 0.135 +/- 0.001 vs UF60' = 0.114 +/- 0.003 mL g(-1)min(-1)*, *p < 0.05). Tubular transport was not affected during the whole experimental period (120 min). on the other hand, the infusion of TsV (10 mu g/mL/min) increased the basal perfusion pressure of isolated arteriolar mesenteric bed (basal pressure: 74.17 +/- 3.42 vs TsV 151.8 +/- 17.82 mmHg*, *p < 0.05). TsV affects renal haemodynamics probably by a direct vasoconstrictor action leading to decreased renal flow. (c) 2005 Elsevier Ltd. All rights reserved.

This study compared the evolution of posture, tone and neonatal reflexes in preterm infants without clinical or neurological complications before and after the age of term using the scale of Saint-Anne Dargassies. To reach the age of the term, was applied Scales Amiel-Barrier-Shnider changed and the Prechtl, traditionally used in the evaluation of term newborns, looking for possible changes to the term, while also evaluating the sensitivity of these scales. We studied 20 non-complicated preterm infants, both sexes aged 32-36 weeks, born in Januário Cicco Maternity School, from August 2006 to August 2007. Was applied to the scale of Saint-Anne Dargassies every two weeks until reach the term, and the range of Amiel-Barrier-Shnider changed and the Prechtl, after reaching 39 and 41 weeks. The evaluation result of articular angles was subjected to the test of Friedman ANOVA, significant differences between the three measurements of the scale of Saint-Anne Dargassies only for angles heel-to-ear to term. Neonatal reflexes changed in the period of prematurity were the cardinal points reflexes, Moro reflexes, cross extensions reflex and the automatic walking reflexes. The posture was the parameter which remained unchanged in the three scales. Considering a significance level of 5% by applying Cochran Q Test, it was found that the scale of Saint-Anne Dargassies is more sensitive to detect suspects. With this methodology and the results it was possible to prepare a manuscript: The neurological examination of non-complicated preterm newborns using the Sanit-Anne Dargssies Scale from birth to term: normal or altered? In which we describe that despite the good clinical condition, the RNP show changes in tone and neonatal reflexes. These data are important because though non-complicated RNP need further attention its maturation process, enabling us to detect and intervene early. With these results we can build a scale simplified neurological assessment made with items found most altered during the application of three scales. The development of this project has a multidisciplinary approach, because it involved Paediatric Neurologist, Physiotherapist and Neonatologist, as recommended by PPGCSA

Arginine was hypothesized to be a model compound in the present study on molecular forms of indispensable amino acid (IAA) dietary supplementation. Juvenile South American pacu (Piaractus mesopotamicus) were fed diets containing arginine in a protein base (casein-wheat gluten or casein-gelatin), or the casein-wheat gluten base supplemented with dipeptide or free arginine at two levels (5 and 10 g kg(-1)). Growth and protein efficiency ratios were significantly affected by diets, but not by arginine molecular form. Three free dispensable amino acids (DAA) and four IAA in plasma were affected by diet, but plasma arginine concentrations did not differ. Plasma urea concentrations, being very low in the pacu, and hepatic arginase activities, were not affected by diet (P = 0.10-0.11), but together with plasma ornithine, mirrored the growth data. Molecular form of arginine supplementation, free or dipeptide, significantly changed several free IAA (Phe, Leu, Ile, His) and urea, with a higher mean plasma concentration in dipeptide fed fish. The dietary treatments, or molecular form of the arginine supplementation, did not change proximate composition, except that calcium levels decreased with higher dietary arginine supplementation level. The present study indicates that dipeptides can provide IAA to pacu, and that arginine supplemented in this form is utilized as efficiently as in free form.

A hemiparesia consiste no déficit da força muscular, com consequente debilidade na mão e no pé, afetando um dos lados do corpo. A literatura mostra poucos estudos enfocando detalhadamente as funções cognitivas e emocionais de crianças afetadas por essa condição neurológica. Este estudo teve como objetivo realizar avaliação neuropsicológica de 23 crianças e adolescentes, de ambos os gêneros, com idades entre 5 anos e 4 meses e 16 anos e 6 meses, com hemiparesia congênita e adquirida. Aplicou-se uma bateria de testes específica para avaliação de funções cognitivas superiores incluindo processos intelectuais, atenção, função perceptiva, função motora, praxias, gnosias, linguagem, memória e função visuomotora. Em relação aos aspectos emocionais, foi usado o teste do desenho da figura humana, visando-se a avaliação da percepção da imagem corporal dos pacientes. Os resultados mostraram que a hemiparesia da criança conduz a déficits em funções neuropsicológicas importantes, além de déficit motor e alterações na esfera emocional, mais precisamente aquelas relacionadas com a representação da imagem corporal. A abrangência multidisciplinar, envolvendo a neurologia pediátrica e a psicologia, engrandeceu o trabalho, referendando os resultados obtidos em todos os seus aspectos

The epilepsy is one of the neurological disorders more common in the pediatric period, and which interferes significantly in the psycho and social life of children and teenagers. The objective of this study was analyzing the practice of sedentary practices, physicals, traditional infant fun and games of children and teenagers with and without epilepsy. The study was prospective, transversal descriptive, done with 60 children and teenagers with epilepsy (Epileptic Group - EG) patients from Pediatric Neurology Clinic of the Centre Integrated Health Lineu Araújo and 60 children and teenagers without epilepsy (Control Group - CG) students from municipal public school, both of the two groups paired with the same age (age group 7 to 14 years) of both the genders (female = 25/41,6% and male = 35/58,3%) of the Teresina city Piauí. It was done two pattern questionnaires, one applied to children and teenagers of the EG and CG to identify the sedentary activities, physical and traditional infant games and other to the parents/responsible of the EG about the clinical and demographic information. The results permitted the elaboration of two manuscripts: a) the first one titled The Practice of Sedentary and Physical Activities of Children and Teenagers with Epilepsy which showed significant difference in the sedentary activities of playing with car toy (p=0,021) to the EG and reading to the CG (p=0,001); in the physical activities the school physical education (p=0,001) and riding a bike (p=0,014) to the CG; b) the second one The Practice of Infant Games and Fun the children and teenagers with and without Epilepsy in this one the playing with marble presented significant difference (p=0,016) to the CG, despite the girls of the two groups don t do this activity. Observing the distribution of frequencies, it was verified that in the play catch-up and hide-and-seek and burn the EG plays more than the CG both in female and male gender. The girls of the EG play less skip, 60 while the boys of the two groups don t play. Elastic jump the girls of the two groups play in a same frequency and the boys don t participate of this fun. The seizures were found to occur during: soccer (23,3%); hide-and-seek (6,6%) and running (3,3%). In the sedentary activities, seizures were reported to occur: resting and watching TV (18,3%), sleeping (36,0%); sitting (13,3%) and lying down (11,7%). Our results showed that the epileptic group and the controls group engage in the same activities, although the epileptic group participates less than the controls. Although the EG had presented a bigger percentage of generalized attacks, they don t occur during the practice of formal physical activities. The research was developed by a multidisciplinary team, and this contributed a lot to the realization of this study

Metacromasia para identificacao de basofilos sanguineos em surubim hibrido: contribuicao metodologica. Revista Brasileira de Medicina Veterinaria, 33(3):147-150, 2011. Centro de Aquicultura da Unesp/Jaboticabal Rod. Paulo Donato Castellane, s/n Bairro Rural, Jaboticabal, 14884-900, SP. Brasil. E-mail: santiagopadua@live.comDifferent protocols of fixation and hydrolysis of blood smears of hybrid surubim catfish for metachromasia to marking blood basophils were evaluated. For this reason, methanol, acid-alcohol and formalin vapor were tested as fixatives. For hydrolysis of blood smears, HCl, citric acid and 2-Mercaptoethanol + Urea + NaCl solutions was evaluated. After procedures, the blood smears was stained with toluidine blue (0.025%) diluted in McIlvaine buffer (pH 4). The different protocols for fixation and hydrolysis of blood smears for metachromasia influenced the quality of the reaction. Hydrolysis with 2-Mercaptoethanol + Urea + NaCl solutions provided negative results when using methanol and acid-alcohol as fixatives. The fixation with acid-alcohol associated with citric acid hydrolysis provides highest quality reason.

Epilepsy is a chronic disorder of the central nervous system, most frequently characterized by abnormal electrical impulses in the brain. It is the oldest recorded neurological disease and has been surrounded by myths, mistaken beliefs and preconceptions. Three professionals work with epileptic patients on a daily basis: teachers, physical educators and physicians . This study aimed to analyze and compare the level of knowledge, preconceptions and attitudes of undergraduate students in the courses of Pedagogy, Physical Education and Medicine, future professionals who will deal with epileptic patients. This descriptive observational study was conducted with 286 university undergraduates of both sexes (women 99/34.6% and men 187/65.4%) from the first to fourth year of Pedagogy, Physical Education and Medicine courses at the Universidade Estadual Rio Grande do Norte (UERN), with mean age of 23 years. A validated and adapted 17-question questionnaire, divided into nine knowledge-based questions, five related to preconceptions and three on attitudes, was applied. Results allowed elaboration of a manuscript entitled Comparative Analysis of Knowledge, Attitude and Preconceptions in University Undergraduates of Pedagogy, Physical Education and Medicine Courses in Relation to Epilepsy. The findings of this article show that knowledge of epilepsy in the three groups is very satisfactory. The low level of preconception indicates that educational or clarifying information is being transmitted, albeit by television, a layman s information vehicle, which has undoubtedly contributed to reducing the stigma of epilepsy through educational information. Results also suggest a lack of knowledge on how to act during a seizure, especially in education professionals. Although there are limitations in our sample, the relevance and contribution of this study is to call attention to the importance and need for these future professionals to be informed and learn correct attitudes with respect to epilepsy during their academic formation. This is essential at a time when the disease is being brought out of the shadows. This research was supported by the Office of the Dean of Teaching, and Deans of Pedagogy, Physical Education and Medicine at UERN. The research was made possible by the multidisciplinary interaction among a physical educator, child neurologist and statistician, all contributing to achieving the aims set out here

O objetivo do nosso projeto foi determinar as características dos recém nascidos com crises convulsivas internados em unidades de terapia intensiva. Foi realizada uma pesquisa multicêntrica, observacional, prospectiva, cuja população alvo foi os recém nascidos com crises convulsivas internados em unidades de terapia intensiva, envolvendo equipe multidisciplinar constituída por neurologista infantil, neonatologistas, intensivistas pediátricos, enfermeiros, técnicos de enfermagem e fisioterapêutas. As crises foram definidas pelo critério clínico, com classificação de Volpe. Variáveis relacionadas à gestação, ao parto, características dos recém nascidos, aspectos das crises convulsivas e mortalidade foram analisadas. Estatística: descritiva (freqüências, medidas de tendência central e dispersão) e análise (teste de probabilidade, teste de risco e de acurácia). Comparamos as crises clínicas entre os recém nascidos de termo e pretermo e observamos diferenças com significância estatística na idade de início das crises, mais tardia nos prematuros, na etiologia predominante: hemorragia peri-intraventricular no prematuro e encefalopatia hipóxico-isquêmica no termo e tipo clínico de crise, clônica no pretermo e sutil no termo. Os testes de acurácia utilizados para determinar se o tipo clínico de crise convulsiva é predictor da etiologia da mesma não revelaram resultados positivos. Quanto às características associadas à mortalidade de prematuros com crise convulsiva, observamos associação entre ventilação mecânica e pneumonia com a mortalidade. Existem diferenças clínicas quando comparamos os recém nascidos pretermo e de termo com crises convulsivas, confirmando dados da literatura

Ferritin is a protein composed of heavy and light chains, non-covalently linked and which accommodates, in its core, thousands of atoms of iron. Furthermore, this protein represents the stock of iron in the body and it is characterized as an acute marker and predictor of diseases, such as iron deficiency anemia, hereditary hemochromatosis and others. Considering the variability of reference values and the analytical methods currently available, the aim of this work was to propose 95% confidence intervals for adults in the State of Rio Grande do Norte, Brazil, after determining the average concentration of serum ferritin for both sexes, beyond its correlation with the age. We analyzed 385 blood samples, collected by venipuncture from individuals residing in the State, after 12-14 hours of fast. The populational sample had 169 men and 216 women between 18-59 years old, which filled a questionnaire on socioeconomic, food habits and accounts about previous and current diseases. The sample collections were itinerant and the results of erythrogram, fasting glucose, alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transferase, urea, creatinine, leukocyte count and platelets, beyond C-reactive protein, were issued to each participant, so that, after selection of the apparently healthy individuals, the dosage of serum ferritin was carried out. Statistical analysis was performed using the softwares SPSS 11.0 Windows version, Epi Info 3.3.2 and Graf instant pad (version 3.02), and the random population sample was single (finite population), for which the test of linear correlation and diagram of dispersion were also made. After selection of individuals and determination of serum ferritin, the most discrepant outliers were disregarded (N = 358, Men = 154/Women = 207) and the average value determined for the masculine sex individuals was 167,18 ng / dL; for the feminine sex individuals, the average value obtained was 81,55 ng / dL. Moreover, we found that 25% of men had values < 90,30 ng / dL; 50% ≤ 156,25 ng / dL and 75% ≤ 229,00 ng / dL. In the group of women, 25% had values < 38,80 ng / dL; 50% ≤ 65,00 ng / dL and 75% ≤ 119,00 ng / dL. Through the correlation coefficient (r = 0,23 with p = 0,003), it is possible to suggest the existence of positive linear correlation between age and serum ferritin for men. The correlation coefficient for women (r = 0,16 with p = 0,025) also confirms the existence of positive linear correlation between serum ferritin and age. Considering the analysis carried out and specific methods corroborating with the proposed benchmarks, we concluded that the average value found for men is higher than that found for women. Furthermore, this scenario rises with age for both sexes, and the 95% confidence intervals obtained were 74 ng/dL ≤ μ ≤ 89 ng/dL and 152ng/dL ≤ μ ≤183ng/dL for the feminine and masculine sex individuals respectively
