Impacto do exercĂcio fĂsico isolado e combinado com dieta sobre os nĂveis sĂ©ricos de HDL, LDL, colesterol total e triglicerĂdeos Impact of isolated and combined with diet physical exercise on the HDL, LDL, total cholesterol and triglycerides plasma levels
Adequados hábitos alimentares e a prática de exercĂcios fĂsicos exercem efeito benĂ©fico sobre as dislipidemias. Se associados, podem ainda otimizar as mudanças do perfil lipoprotĂ©ico plasmático, sendo, alĂ©m disso, intervenções de custo moderado quando comparados com tratamentos medicamentosos e dependentes de alta tecnologia. Este estudo tem por objetivo avaliar o impacto do exercĂcio fĂsico isolado e combinado com dieta sobre o perfil lipĂdico em indivĂduos com sobrepeso/obesos. O presente trabalho Ă© do tipo retrospectivo analĂtico observacional. Nele foi analisada a evolução do perfil lipĂdico e do peso, por perĂodo entre trĂŞs e seis meses, de 30 indivĂduos, divididos em dois grupos: grupo exercĂcio (prática de exercĂcio fĂsico) e grupo dieta (prática de exercĂcio fĂsico associada Ă intervenção nutricional). Foram encontradas reduções estatisticamente significativas no CT (-14,4mg/dl; P = 0,022) e no LDL-c (-20,9mg/dl; P = 0,013) para os componentes do grupo exercĂcio. Tal redução tambĂ©m ocorreu em relação Ă razĂŁo CT/HDL-c (-0,9; P = 0,005) para os componentes do grupo dieta. Foi observada elevação dos nĂveis de HDL-c, apenas no grupo dieta (+4,2 mg/dl). Nesse mesmo grupo verificou-se diminuição no CT (-8mg/dl) e no LDL-c (-9,8mg/dl), bem como redução de peso (-2,6kg), no entanto, tais resultados nĂŁo foram estatisticamente significativos. Quanto aos nĂveis de TG, nĂŁo foi verificada evolução positiva em ambos os grupos. Concluiu-se que o efeito isolado do exercĂcio fĂsico foi mais evidente em relação Ă s variáveis CT e LDL-c. Os TG nĂŁo sofreram modificações positivas com a prática exclusiva de exercĂcios fĂsicos ou com sua associação Ă dieta. Para as variáveis HDL-c e peso, a combinação da dieta com o exercĂcio fĂsico apresentou maiores benefĂcios.<br>Adequate eating habits and physical exercise have a beneficial effect on dislipidemies. When associated, they might even optimize changes to the plasmatic lipoproteic profile, apart of which they are moderate-cost interventions if compared to drug-based and high-tech depending treatments. The present study aims at assessing the impact of physical exercise as isolated and combined with a diet on the lipidic profile of overweight/obese individuals. Tn observational analytical retrospective study has looked into the evolution of the lipidic profile and weight over a period of 3 to 6 months of 30 individuals divided in two groups: the exercise group (physical exercise practice) and the diet group (physical exercise associated with a nutritional intervention). Significant statistical reductions were found in the CT (-14.4 mg/dl; P=0,022) and in the LDL-c (-20.9 mg/dl; P = 0,013) for the components in the exercise group. Such reduction has also occurred regarding the CT/HDL-c (-0,9; P = 0,005) ratio for the components of the diet group. The increase in the HDL-c levels was observed only in the diet group (+4.2 mg/dl). In this same group a decrease in the CT (-8 mg/dl) and in the LDL-c (-9,8 mg/dl) was observed as well as a weight reduction (-2.6 Kg), however, such results have not been statistically significant. Regarding the TG levels, there was no evidence for a positive evolution in either group. As a conclusion, the isolated effect of physical exercise was more evident concerning the variables CT and LDL-c. The TG did not undergo positive modifications upon the exclusive practice of physical exercise or with their association with the diet. As for variables HDL-c and weight, the combination of diet and physical exercise has proven to bring enhanced benefits
Maturational changes in automated EEG spectral power analysis in preterm infants
Item does not contain fulltextOur study aimed at automated power spectral analysis of the EEG in preterm infants to identify changes of spectral measures with maturation. Weekly (10-20 montage) 4-h EEG recordings were performed in 18 preterm infants with GA <32 wk and normal neurological follow-up at 2 y, resulting in 79 recordings studied from 27(+4) to 36(+3) wk of postmenstrual age (PMA, GA + postnatal age). Automated spectral analysis was performed on 4-h EEG recordings. The frequency spectrum was divided in delta 1 (0.5-1 Hz), delta 2 (1-4 Hz), theta (4-8 Hz), alpha (8-13 Hz), and beta (13-30 Hz) band. Absolute and relative power of each frequency band and spectral edge frequency were calculated. Maturational changes in spectral measures were observed most clearly in the centrotemporal channels. With advancing PMA, absolute powers of delta 1 to 2 and theta decreased. With advancing PMA, relative power of delta 1 decreased and relative powers of alpha and beta increased, respectively. In conclusion, with maturation, spectral analysis of the EEG showed a significant shift from the lower to the higher frequencies. Computer analysis of EEG will allow an objective and reproducible analysis for long-term prognosis and/or stratification of clinical treatment
