RESUMO
Background: Stroke is one of the major global health problems. Stroke is the most common clinical manifestation of cerebrovascular disease of which more than 99% are due to arterial involvement and less than 1% due to venous involvement in the form of Cerebral Venous Thrombosis (CVT). Among arterial causes 85% are due to infarction and 15% due to haemorrhage.1,2 There is difference in serum lipid levels in subtypes of strokes to guide lipid-lowering therapy which can reduce incidence of stroke and stroke related mortality by adapting primary and secondary preventive measures.3,4 Authors have endeavoured to correlate severity of lipid derangement and stroke.Methods: In this study 64 consecutive eligible ischaemic stroke cases and 64 eligible hemorrhagic stroke cases would be included. Cases of strokes will be divided into ischaemic and hemorrhagic as per clinical features and with help of brain imaging by CT scan and MRI at the time of admission and 8 hour fasting lipid profile was collected from all cases. All this information will be filled in preformed format.Results: Serum lipid profile of two categories of stroke showed raised serum total cholesterol in 39.1% patients of ischaemic stroke in contrast to 18.8% patients with haemorrhagic stroke (p=0.019).Stroke patients showed raised in LDL cholesterol in 29.7% patients of ischaemic stroke in contrast to 9.4% patients with haemorrhagic stroke, (p=0.007).Conclusions: Based on the finding of our study we conclude that ischemic stroke patient had higher lipid derangement as compare to haemorrhagic stroke in terms of raise total cholesterol, LDL cholesterol and decrease HDL cholesterol.
RESUMO
Objetivo: Evaluar el efecto del ejercicio físico sobre los niveles de las subpoblaciones HDL, enzima lecitina-colesterol acil-transferasa y la proteína transportadora de ésteres de colesterol en estudiantes de Medicina. Método: La población se dividió de manera voluntaria en 2 grupos: ejercicio y no ejercicio. Se midieron perímetro abdominal e índice de masa corporal, subfracciones de HDL2 y HDL3 por precipitación iónica, y enzima lecitina-colesterol acil-transferasa y proteína transportadora de ésteres de colesterol mediante Enzyme-Linked Immuno Sorbent Assay (ELISA). Resultados: El perfil lipídico de riesgo aumentó en ambos grupos: las HDL, HDL3 y HDL2 disminuyeron en ambos grupos, pero solo las HDL2 lo hicieron de forma significativa en el grupo que realizó ejercicio. La lecitina-colesterol acil-transferasa y la proteína transportadora de ésteres de colesterol permanecieron sin cambios significativos. Sin embargo, en el grupo que hizo ejercicio hubo disminución estadísticamente significativa de HDL2 y lecitina-colesterol acil-transferasa, en las mujeres. Conclusiones: El ejercicio logra modificar algunas variables como el perímetro abdominal, el índice de masa corporal y las HDL3. Estas modificaciones son dependientes del género, pero, a pesar de la intervención de 3 meses con un programa de ejercicio, este no logra reducir los factores de riesgo lipídico en esta población de estudiantes de Medicina, debido a que su entorno hace muy compleja la respuesta metabólica al ejercicio.
Objective: To evaluate exercise effect on HDL subpopulations, lecithin-cholesterol acyltransferase enzyme and ester transfer protein cholesterol levels in medical students. Method: Population was divided voluntarily into 2 groups, exercise and no exercise. Waist circumference and body mass index were measured; subfractions HDL2 and HDL3 by ion precipitation and LCAT and CETP enzymes Enzyme-Linked Immuno-Sorbent Assay (ELISA). Results: Lipidrisk profile increased in both groups; HDL, HDL2 and HDL3 decreased in both groups, but only the HDL2 decreased significantly in students who exercised. LCAT and CETP remained without significant changes, however, in the exercise group, there was statistically significant decrease in HDL2 and LCAT in women. Conclusions: This study shows that exercise does alter some variables such as waist circumference, body mass index and HDL3. These changes are dependent on gender, but despite the intervention of 3 months with an exercise program, it fails reducing lipid risk factors in this medical student populations, given their environment, which complicates their metabolic response to exercise.
