Full textAbstract:
Anemi kan uppstå till följd av förlust av erytrocyter eller försämrad produktion av nya erytrocyter. För att upptäcka och följa upp patienter med anemi är det viktigt att korrekt kunna mäta hemoglobinkoncentrationen (Hb) i blodet. En vanlig metod för att mäta Hb-koncentration är fotometri i kombination med en kemisk omvandling. Liksom alla mätningar med ljus är dessa känsliga för turbiditet i provet. Lipemi är en vanlig källa till turbiditet som kan uppstå till exempel som följd av en fettrik måltid, diabetes mellitus, lever- eller njursjukdomar, alkoholism och vissa läkemedel. Olika instrumenttillverkare har olika metoder för att motverka interferensen av lipemi. Sysmex hematologi-instrument XN-10 använder en fettlösande bärarvätska i sin fotometriska kanal (HGB) och HemoCue mäter vid en andra våglängd som ska kompensera för turbiditet. Sysmex XN-10 har också en optisk kanal (HGB-O) som är till för att räkna retikulocyter genom att mäta deras nukleinsyra- samt Hb-innehåll men ger då också ett beräknat värde på Hb-koncentrationen i hela provet. Syftet med denna studie var att jämföra HGB och den HGB-O för bestämning av Hb-koncentrationen i helblod. Båda kanalerna jämfördes även med HemoCue Hb 201+ vid bestämning av Hbkoncentrationen i svårt lipemiska prover. Hb-mätning på plasma från motsvarande prover utfördes också för att undersöka om värdet motsvarade Hb-höjningen i de lipemiska proverna. Prover analyserade med både HGB och HGB-O på Sysmex XN-10 på klinisk kemi vid Skånes universitetssjukhus i Lund under november månad 2018 (n = 392) jämfördes med hjälp av Spearmans rangkorrelationskoefficient. Lipemi simulerades med fettemulsionen Intralipid i totalt 32 prover. Färdiganalyserade patientprover från föregående dag delades i ett lipemiskt prov med Intralipidtillsats och ett nollprov med tillsats av NaCl-lösning i en motsvarande volym. Differenserna mellan de lipemiska- och nollprovernas Hb-värden testades för signifikans med icke-parametrisk Wilcoxons teckenrangtest. Kruskal-Wallis samt Dunns's tester användes för att visa på signifikanta skillnader mellan de tre metoderna. Signifikansnivån sattes vid p < 0,05. Resultaten visade god korrelation mellan HGB - och HGB-O Hb-värden med ett Spearman korrelationsvärde på 0,982. Jämförelsen av metoderna vid lipemi visade signifikant skillnad mellan nollprov och lipemiskt prov för HGB- (p < 0,001) men inte HGB-O (p = 0,11) på XN-10. HemoCue Hb 201+ visade också signifikant skillnad (p < 0,001) vid lipemi men med lägre median-värde än HGB och mindre spridning än HGB-O. HGB-O:s median-värde tydde på minst lipemipåverkan men spridningen av differenserna var stor. Spridningen av HGB-O resultaten kan bero på hemolys då endast intracellulärt Hb mäts i denna kanal. Resultaten i denna studie tyder på att HemoCue-metoden är den mest pålitliga vid Hb-mätning av lipemiska prover och därmed det lämpligaste komplementet till HGBmetodenAnemia can arise from either loss of erythrocytes or impaired production of new erythrocytes. In order to discover and evaluate the treatment of anemic patients, correct Hb measurements are important. A common method to measure Hb concentration is photometry in combination with chemical conversion of the Hb. Like all light-dependent methods this suffers from a vulnerability to turbidity that scatters light. Lipemia is a common cause of turbidity caused by e.g. recent intake of high fat foods, diabetes mellitus, liver or kidney disease, alcoholism and some drugs. Manufacturers of Hb analyzers use different methods to counter the influence of interference from lipemia on measurements. Sysmex XN-10 analyzers use a fat dissolving sheath fluid in its photometric channel (HGB) and HemoCue measures absorbance at a second wavelength to compensate for turbidity. Sysmex XN-10 also has an optic channel (HGB-O) for counting reticulocytes by measuring their nucleic acid and Hb content. At the same time this channel measures Hb equivalents of erythrocytes and gives a calculated value of Hb content in the entire sample. The aim of this study was to compare the photometric and the optical channels for measuring Hb concentration in whole blood. Both the Sysmex XN-10 channels were compared with HemoCue Hb 201+ when measuring Hb concentrations in lipemic samples. Plasma Hb concentration was determined for the corresponding samples in order to investigate correlation between elevation in Hb concentration with and without simulated lipemia and in the plasma after centrifugation. Samples analyzed at Skånes University Hospital in Lund during the month of November 2018 (n = 392) using both HGB and HGB-O on XN-10 were compared using Spearman's signed correlations coefficient. Lipemia was simulated by using the fat emulsion Intralipid in a total of 32 samples. Samples collected and analyzed on the previous day was used for the study. Each sample was split into one part with added Intralipid to form a lipemic sample and one part with NaCl-solution of the same volume as Intralipid in the lipemic sample. The differences between lipemic and non lipemic samples was tested for significance by the non-parametric Wilcoxons signed ranks test for each of the methods. Significance between the three methods was tested by using Kruskal-Wallis and Dunn's tests. Level of significance was set to p < 0.05. The results showed good correlation between earlier test run on both HGB and HGB-O with a Spearman correlation score of 0,982. A significant difference was found between lipemic and non lipemic samples with the photometric method (p < 0,001) but not the optical method (p = 0,11) on XN10. HemoCue Hb 201+ also showed a significant difference (p < 0,001) between lipemic and non lipemic samples but a lower median than HGB and less deviation than HGB-O. The median of HGB-O indicated that it was influenced the least by lipemia of the three methods but had the greatest deviation of the differences. The greater deviation of HGB-O values may have been caused by hemolysis since the method measures intra cellular Hb. HemoCue shows according to this study the slightest deviation of the three methods and a less heightened median value compared to HGB which confirms the methods suitability as complement to HGB when dealing with lipemic samples.

Full textAbstract:
Prediction for future coronary artery disease (CAD) from high-density lipoprotein (HDL) and triglyceride (TG) measurements are based off of a single measurement that has been shown to be variable. To better determine risk for CAD based on blood lipids, studies in the postprandial state are warranted. To assess the reproducibility of TG clearance, 10 men underwent three trials of a 70g oral fat loading test with blood samples collected every two hours for eight hours. These trials were all scheduled at least one week apart. Men who had fasting TG concentrations > 250 mg - dL -' were excluded from the study. Each subject presented to the laboratory having abstained from exercise for 24 hours and alcohol 72 hours prior to the upcoming trial. Each subject was also provided with a standardized frozen dinner to eat the night before at a time which allowed the subject to be 12 hours fasted for the next days' trial. To specifically assess postprandial lipemia, TG concentrations were plotted against bi-hourly collection times to form a curve. The area under this curve was then calculated to determine PPL area. Itwas found that there was no significant difference in area under the TG curve (p = 0.25) for any of the three trials (1096 ± 168, 948 ± 105, and 995 ± 127 mg - dL -' - 8 • hr-' respectively for trials one, two, and three). Pearson correlations between trials were 0.79 for trials one and two, 0.82 for trials two and three, and 0.90 for trials one and three. Also, there was no significant difference in peak TG (p = 0.34) on each of the three trial days (167 ± 27, 150 ± 16, and 151 ± 19 mg • dL -1 in peak TG for trials one, two, and three respectively). Time taken to reach peak TG concentrations (p = 0.20) or time to return to baseline TG (p = 0.27) were not significantly different across three trial days. The men in this study reached peak TG concentrations in this study in 3.2 ± 0.5, 4.0 ± 0.4, 4.0 ± 0.3 hours respectively for trials one, two, and three. Time to return to baseline was 6.8 ± 0.6, 7.4 ± 0.4, 7.8 ± 0.4 hours for trials one through three respectively. Correlations between trials and the lack of a difference between trials using repeated measures ANOVA in regards to PPL area gives some preliminary evidence that some postprandial measures such as PPL area and can be reproduced across trials. However, the intra-individual variation was 19 ± 4% which provides no additional support for reproducibility of PPL. Additionally, results from this study, as well as all others pertaining to the study of reproducibility of PPL are specific to the protocol used and the method of interpretation.School of Physical Education

Full textAbstract:
The regulation of the serum triglyceride responses to fat ingestion have been examined in normolipidemic men. To evaluate the existing methods for comparing chylomicron-triglyceride clearance, the oral and intravenous fat tolerance tests and a steady state duodenal perfusion method were compared. Good correlations (r > 0.8) were found between each of these methods. Since the intravenous fat tolerance test is independent of fat absorption, these data suggested that the serum triglyceride response to fat feeding was largely determined by the rate of chylomicron-triglyceride clearance. To determine the influence of the quantity and type of meal fat on postprandial serum triglyceride concentrations, the serum triglyceride responses to three different doses of dairy cream, and to standard doses of olive and sunflower oil were examined. For a given type of fat, the magnitude of postprandial lipemia (the integrated serum triglyceride excursion) varied directly with the quantity of fat in the meal. This finding suggested that the chylomicron- triglyceride clearance system(s) did not become saturated even after large fat meals. In addition, it appeared that the hormonal factors released in response to fat ingestion (some of which are known to increase lipoprotein lipase activity in vitro) did not increase the rate of chylomicron-triglyceride clearance. If the quantity of fat in a meal was fixed, then postprandial lipemia increased with increasing saturation of the triglyceride fatty acids. These differences did not appear to reflect differences in triglyceride absorption. Since acute fat feeding per se did not appear to stimulate chylomicron-triglyceride clearance, the effects of dietary proteins and carbohydrates were studied. The addition of up to 35g protein to a standard test meal did not affect postprandial lipemia. These results were supported by the observation that protein ingestion did not affect intravenous fat tolerance. Postprandial serum triglyceride concentrations were significantly influenced by carbohydrate ingestion. Fructose (50g) and sucrose (100g) markedly increased postprandial lipemia, although glucose ingestion did not. In agreement with earlier studies, glucose ingestion decreased serum triglyceride concentrations 2 hours after the meal. This effect was abolished by intraduodenal fat administration and by substituting starch for glucose in the test meal. The effects of glucose could be reproduced by iso-osmotic quantities of urea, however. These findings suggested that glucose ingestion did not increase chylomicron -triglyceride clearance. It is more likely that glucose delayed the absorption of triglycerides by slowing gastric emptying, and that this effect was partly related to the increased osmolarity of glucose- containing meals. The effects of chronic exercise on postprandial lipemia and chylomicron-triglyceride clearance were determined in endurance- adapted athletes. The serum triglyceride responses to large and small fat meals were lower in athletes than in sedentary men with comparable fasting triglyceride concentrations. These differences were not eliminated by a single bout of acute exercise in the sedentary men. The clearance of intravenously administered lntralipid, and chylomicron -triglyceride clearance assessed from steady state chylomicron-triglyceride concentrations during duodenal fat perfusion were faster in athletes than in the sedentary men. These data suggested that the low postprandial lipemia in athletes reflects increased chylomicron-triglyceride clearance caused by increased activity of the triglyceride clearing system(s). Given these considerations. it appears that the pathway(s) for chylomicron triglyceride clearance are extremely efficient in normal men and that these pathways are not subject to acute physiological regulation.

Full textAbstract:
La lipémie postprandiale se caractérise par une augmentation des lipoprotéines riches en triglycérides après un repas, et joue un rôle important dans la biodisponibilité des lipides alimentaires pour les tissus périphériques. En effet, une lipémie postprandiale élevée est souvent associée à l'obésité et à une dyslipidémie, deux composantes du syndrome métabolique qui peuvent engendrer des complications médicales, incluant diabète et maladies cardiovasculaires. La lactoferrine (Lf) inhibe l'épuration hépatique des chylomicrons, conduisant à une élévation de la lipémie postprandiale par des mécanismes moléculaires non élucidés. Il est aussi établi que le Lipolysis Stimulated Receptor (LSR) contribuait à l'épuration des lipoprotéines riches en triglycérides pendant la phase postprandiale. L'objectif était de déterminer s'il existait une interaction entre la Lf et le LSR. Les études de cultures cellulaires ont montré que si la Lf n'affectait pas le taux d'expression du LSR dans des cellules Hepa 1-6 de souris, elle co-localisait avec le LSR en présence d'oléate, un composé requis pour l'activation du récepteur. Des expériences de ligand-blotting ont également montré que la Lf se fixait sur le LSR purifié et inhibait la fixation de lipoprotéines riches en triglycérides. Les domaines N et C-terminaux isolés de cette protéine, ainsi qu'un mélange de peptides obtenu après double hydrolyse de la Lf par la trypsine et la chymotrypsine, conservent cette propriété. Nous proposons que l'élévation de la lipémie postprandiale observée in vivo suite à un traitement par la Lf soit médiée par son interaction avec le LSR, inhibant ainsi l'épuration des chylomicrons et de leurs remnantsPostprandial lipemia is characterized by an increase in plasma triglyceride-rich lipoproteins after the ingestion of meal, and is important towards determining the bioavailability of dietary lipids amongst the peripheral tissues. Indeed, elevated postprandial lipemia is often observed with obesity and dyslipidemia, two disorders that can lead to health complications including diabetes and cardiovascular diseases. Lactoferrin (Lf), has been shown to inhibit hepatic chylomicron remnant removal, resulting in increased postprandial lipemia, for which the molecular mechanisms remain unclear. The lipolysis stimulated lipoprotein receptor (LSR) has been shown to contribute to the removal of triglycerides-rich lipoproteins during the postprandial phase. The aim was to determine if there was interaction between Lf and LSR. Both Lf and LSR were purified with purities upper to 95% and characterized. Cell culture studies demonstrated that while Lf does not have any significant effect on LSR protein levels in mouse Hepa1-6 cells, it co-localizes with LSR in cells, but only in the presence of oleate, which is needed to obtain LSR in its active form. Ligand blotting using purified LSR revealed that Lf binds directly to the receptor in the presence of oleate and prevents the binding of triglycerides-rich lipoproteins. Both C- and N-lobes of Lf, and a mixture of peptides derived from its tryptic and chymotryptic double hydrolysis retained the ability to bind LSR. We propose that the elevated postprandial lipemia observed upon Lf treatment in vivo is mediated by its direct interaction with LSR, thus preventing clearance of chylomicrons and their remnants through the LSR pathway

Previous issue date: 2005INTRODUÇÃO: O teor adequado de lipídios de diversas origens é um dos assuntos mais discutidos atualmente em nutrição humana, sendo a associação entre gordura dietética, obesidade e doenças cardiovasculares bastante controvertida. OBJETIVO: Estudar os efeitos da dieta rica em lipídios (60% da energia total) de origem animal e vegetal no perfil lipídico e peso corporal. MATERIAL E MÉTODO: O estudo foi realizado com 8 voluntárias adultas saudáveis que participaram dos dois grupos experimentais (Grupo Gordura Animal - GA e Grupo Gordura Vegetal GV) com duração de 14 dias cada. O peso corporal foi determinado antes de cada dieta experimental e a cada 2 dias durante o experimento. Os lipídios circulantes foram dosados nos dias 0 e 15 de cada período experimental através do método enzimático. RESULTADOS: A perda de peso significativa (p<0,05) foi observada nos dois grupos experimentais (GA e GV). No GV não houve alteração nos lipídios circulantes, porém no GA ocorreram alterações significativas (elevação do HDL-colesterol e redução do LDL-colesterol). CONCLUSÃO: A natureza da gordura não alterou o efeito sobre o peso corporal, ambos os grupos perderam peso. Os conceitos largamente difundidos sobre a associação entre gordura de origem animal e aumento de peso bem como, hiperlipemias e doenças cardiovasculares precisam ser revisados

Full textAbstract:
Recent research has shown that the combination of high triglyceride (TG) levels and low high density lipoprotein (HDL) levels, significantly increases the incidence of coronary artery disease (CAD). The incidence of CAD is also increased in abdominally obese individuals. To assess differences in postprandial TG clearance patterns between abdominally obese (AO) and controls (C), fourteen healthy, normolipidemic males (seven controls and seven abdominally obese) completed an oral fat loading test (78 grams of fat). Blood samples were collected every hour for eight hours. Abdominally obese individuals had significantly greater TG values, significantly lower total HDL and HDL2 values and significantly greater area under the TG curve (p = 0.03). Time to reach peak TG and time to reach baseline TG values did not differ between the two groups, even though fewer AO individuals reached baseline within eight hours. The data from the present investigation indicate that increased time to clear TG in AO individuals may be one pathway that increases the incidence of CAD in this group.School of Physical Education

Full textAbstract:
Fundação Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio de JaneiroAs mudanças nos hábitos alimentares têm causado efeitos impressionantes na saúde pública, diretamente relacionados ao aumento da ingestão de refeições ricas em gorduras, principalmente gorduras saturadas. A principal consequência desse consumo é o estado prolongado e excessivo da lipemia pós-prandial (LPP), considerada um dos fatores relacionados às anormalidades metabólicas e aos danos vasculares. O objetivo do estudo foiavaliar o efeito da sobrecarga lipídica na reatividade microvascular em mulheres obesas. Das 41 participantes deste estudo, 21 apresentavam o diagnóstico de obesidade, com IMC de 32,41,6 kg/m2 (média SD) e idade 31,65 anos e 20 mulheres saudáveis, com IMC de 21,91,7 kg/m2 e idade 27,25,5 anos. Após a avaliação clínica e laboratorial, as participantes tiveram a microcirculação examinada por dois métodos: a dinâmica do leito periungueal, para avaliação da densidade capilar funcional (DCF), velocidade de deslocamento das hemácias no basal (VDH) e após uma isquemia de 1 min (VDHmax) e tempo de reperfusão (TVDHmax). A segunda técnica foi a do dorso do dedo para avaliação da DCF no repouso, durante a hiperemia reativa e após oclusão venosa. Foi feita a coleta de sangue para avaliação do colesterol total (CT), triglicerídeos (TG), HDL-c e ácidos graxos livres (AGL), glicose, insulina e viscosidade plasmática em 30 e 50 rotações por minuto (rpm). Também foram medidas a pressão arterial sistólica (PAS), diastólica (PAD) e frequência cardíaca (FC). Após essas análises no repouso, todas as participantes receberam uma refeição rica em lipídios, e após 30, 60, 120 e 180 minutos da ingestão da refeição, os exames de videocapilaroscopia e a coleta de sangue foram novamente realizados.As participantes com obesidade apresentaram, após a sobrecarga lipídica, valores significativamente menores do que no jejum para: DCF basal do dorso do dedo (p=0,02); DCF durante hiperemia reativa (p=0,02), DCF pós-oclusão venosa (p=0,02), HDL-c (p<0,0001), LDL-C (p<0,0001) e AGL (p<0,0001) e valores elevados para: VDH (p<0,0001), VDHmax(p=0,003), TVDHmax (p=0,004), glicose (p<0,0001), insulina (p<0,001), CT (p=0,03), TG (p<0,0001) e FC (p=0,03). Alterações na viscosidade não foram observadas no grupo OB após a refeição quando comparado aos seus valores basais em 30 e 50 rpm (p=0,87 e p=0,42, respectivamente). A PAS foi elevada nas participantes OB após a sobrecarga quando comparada às saudáveis em todo tempo de estudo. Concluímos que alimentos ricos em lipídios podem aumentar ainda mais a disfunção microcirculatória e as alterações metabólicas já presentes em mulheres obesas.
Changes in eating habits have caused striking effects on public health, directly related to increased intake of food rich in fat, mainly saturated fat. The main consequence of this consumption is the excessive and prolonged state of postprandial lipemia (PPL), considered one an important factor related to metabolic abnormalities and vascular damage. The aim of this study was to assess effects of fat overload on microvascular reactivity in obese women. Of the 41 study participants, 21 had the diagnosis of obesity, with BMI of 32.4 1.6 kg/m2 (mean SD) and age of 31.6 5 years and 20 healthy women with BMI of 21.9 1.7 kg/m2and age 27.2 5.5 years. After clinical and laboratorial assessment, participants had the microcirculation examined by two methods: dynamic, using the nailfold bed to assess functional capillary density (FCD), red blood cell velocity in in control conditions (RBCV) and peak (RBCVmax) and time (TRBCVmax) to reach it after 1 min arterial occlusion. The second technique was the finger dorsum to assess FCD at rest and during the reactive hyperemia response and after venous occlusion. Blood sampling was performed to determine total cholesterol (TC), triglycerides (TG), HDL- c and free fatty acids (FFA), glucose, insulin and plasma viscosity at 30 and 50 rotations per minute (rpm). Systolic (SBP) and diastolic (DBP) blood pressures and heart rate (HR) were also measured. After these measurements at rest, all participants received a meal rich in lipids, and after 30, 60, 120 and 180 min after ingestion, videocapillaroscopy exams and blood samples were taken again. Results - Obese participants, after fat overload, presented significantly lower values than at rest at finger dorsum of FCD (p = 0.02), FCD during reactive hyperemia (p = 0.02) and post- venous occlusion (p = 0.02), HDL-C (p <0.0001), LDL-C (p <0.0001) and FFA (p <0.0001) and high values for: RBCV at rest (p<0 ,0001), RBCVmax (p = 0.003), TRBCVmax (p = 0.004), glucose (p <0.0001), insulin (p<0,0001), CT (P = 0.03), TG (P <0.0001) and HR (P = 0.03). Changes in viscosity were not observed in obese group after a meal, when compared to baseline values at 30 and 50 rpm (p = 0.87 and p = 0.42, respectively). SBP was higher in obese participants after overload compared to healthy ones throughout the study period. We conclude that high fat food can further increase microcirculation dysfunction and metabolic abnormalities already present in obese women.

Introdução: Estudos têm demonstrado a associação de doença arterial coronária (DAC) grave com triglicérides (TG) pós prandial. No entanto, a relação entre a aterosclerose leve a moderada e TG pós prandial não está bem estabelecida. No presente estudo avaliamos a relação entre TG pós prandial e DAC detectada por angiografia coronária por tomografia computadorizada (TC cor). Material e Métodos: Foram incluídos 130 pacientes (85 com DAC detectado pelo TC cor coronária e 45 sem DAC), submetidos a um teste de tolerância oral de gordura. Estudamos a lipemia pós prandial medindo TG de T0h para T6H com intervalos de duas horas, e analisamos a mudança TG ao longo do tempo através de um modelo linear misto multivariável longitudinal, utilizando como desfecho primário o log normal do TG. Resultados: Os pacientes com DAC eram mais velhos (56,5 ± 6,8 vs. 50,4 ± 7,1 anos, p < 0,001), predominantemente do sexo masculino (68,2% vs. 37,8%, p < 0,001) e com HDL-colesterol (HDL-C) menor (49 ± 14 vs. 54 ± 12 mg / dl, p = 0,015). A maioria dos indivíduos com DAC tinha aterosclerose leve com doença não obstrutiva (63,5%). Pacientes com DAC tiveram uma depuração mais lenta TG pós prandial de 4h a 6h (p < 0,05) em comparação com pacientes sem DAC. Estes resultados permanecerem significativos mesmo após ajuste para o TG de jejum, idade, sexo, índice de massa corporal e glicemia de jejum. No entanto, essas diferenças não foram significativas após o ajuste para o HDL-C de jejum. Conclusão: Os pacientes com DAC leve e moderada detectados pelo TC cor demonstraram alteração do metabolismo de TG pós prandial, com remoção mais lenta de TG, especialmente entre 4h e 6h quando comparados a indivíduos sem DAC. Esta diferença foi explicada em parte pelo menor HDL-C de jejum no grupo com DAC. Assim, embora TG pós prandial possa contribuir para o desenvolvimento de DAC, esta associação é parcialmente relacionada com a menor concentração de HDL-C em indivíduos com DACBackground: Studies have demonstrated the association of severe coronary artery disease (CAD) with postprandial triglycerides (TG). Nevertheless the relationship between less severe atherosclerosis and postprandial triglycerides is less established. Objective: to study the relationship between postprandial TG and CAD detected by coronary computed tomographic angiography (CTA). Material and Methods: We enrolled 130 patients, (85 with CAD detected by coronary CTA and 45 without); who underwent an oral fat tolerance test. We studied the postprandial lipemia measuring TG from T0h to T6h with 2 hour intervals, and analyzed the TG change over time using a longitudinal multivariable linear mixed effects model with the log normal of the TG as the primary outcome.Results: Patients with CAD were older (56.5 ± 6.8 vs. 50.4 ± 7.1 years, p < 0.001), predominantly male (68.2% vs. 37.8%, p < 0.001) and had lower HDL-cholesterol (HDL-C) (49 ± 14 vs. 54 ± 12 mg/dL, p=0.015). The majority of individuals with CAD had mild atherosclerosis with non-obstructive disease (63.6%). Patients with CAD had a slower clearance of postprandial TG change from 4h to 6h (p < 0.05) compared to patients without CAD. These results remained significant after adjustment for fasting TG, age, gender, body mass index and glucose. However, those differences did not reach statistical significance after adjustment for fasting HDL-C. Conclusion: Patients with mild and moderate CAD detected by coronary CTA had an impaired postprandial metabolism, with a delayed TG clearance, when compared to individuals with no CAD. This difference was partially explained by the lower HDL-C. Thus, though postprandial TG may contribute to the development of CAD, this association is partially related to the low HDL-C in individuals with CAD

Previous issue date: 2004Lipemia pós-prandial alterada é um fator de risco para aterosclerose. Proteína C-reativa de alta sensibilidade (hs-PCR) e leucócitos são marcadores inflamatórios de aterosclerose. Até o momento, não se conseguiu estabelecer a faixa de normalidade da lipemia pós-prandial e o efeito das suas alterações nesses marcadores inflamatórios. O objetivo deste estudo é avaliar o nível de lipemia pós-prandial e da hs- PCR e a contagem de leucócitos em indivíduos saudáveis (controles) e diabéticos tipo 2, após uma refeição teste hiperlipídica. Controles e diabéticos tipo 2 praticamente sem comorbidades, exceto por Hipertensão Arterial Sistêmica (HAS), com idade entre 30-58 anos, de ambos os sexos, eram submetidos a ingestão de uma refeição teste hiperlipídica (56g de gordura) e tinham seus perfis lipídicos (colesterol total, HDL, triglicerídeos), hemograma e hs-PCR realizados no basal (12h de jejum), 3h e 5h pós-refeição. Notouse que os níveis de triglicerídeos (TG) pós-prandiais nos controles e diabéticos foram similares aos encontrados em outros locais do Brasil e do mundo. Controles com níveis de TG maiores que o percentil 50 (TG>160mg/dl às 3h e/ou TG>174mg/dl às 5h) foram considerados hiperresponsivos à refeição teste e tinham maior IMC, maior circunferência abdominal e maiores níveis de PAS. Houve aumento de colesterol total, triglicerídeos e leucócitos às 3h e 5h, com maior intensidade às 5h, e redução de HDL às 3h e 5h, tanto nos controles como nos diabéticos. A redução do HDL nos diabéticos correlacionou-se com maior IMC e maior circunferência abdominal. Não se observaram diferenças no perfil lipídico e nos marcadores inflamatórios pós-prandiais, entre controles e diabéticos. Também, a hipertrigliceridemia pós-prandial não alterou os marcadores inflamatórios em nenhum dos 2 grupos. Conclusões, os níveis de lipemia pós-prandial observados no nosso estudo foram similares aos níveis já vistos em outros estudos nos 2 grupos. Há recrutamento de leucócitos com o aumento da lipemia pósprandial em diabéticos e em não diabéticos. Obesidade central correlaciona-se com redução do HDL pós-prandial nos diabéticos. O tempo de avaliação da lipemia pósprandial e marcadores inflamatórios pós-prandiais, após uma refeição teste, deve ser o mais prolongado possível, já que lipemia pós-prandial e marcadores inflamatórios pósprandiais se alteram mais tardiamente no período pós-prandial

O sangue total passa por processo de centrifugação a fim de que o paciente receba apenas o componente sanguíneo do qual necessita. O controle de qualidade, inicia com inspeção visual, onde são avaliados: coloração, lipemia, presença de coágulos e vazamentos. No Hemocentro Coordenador do Paraná, a principal causa de descarte de plasma fresco (PF) é a lipemia. Os PF turvos são descartados e os respectivos concentrados de hemácias (CH) permanecem em estoque. Durante o armazenamento, os CH passam por processo de alterações bioquímicas e morfológicas conhecido como lesão de armazenamento, cuja última etapa é a hemólise. É comprometida a função terapêutica e segurança transfusional. Alguns autores relatam a relação entre lipemia e hemólise. Lipemia é o aspecto turvo do plasma, devido à presença de lipoproteínas e tem relação principalmente com a dieta do doador. O objetivo deste estudo foi comparar os parâmetros de qualidade dos CH que tiveram os plasmas descartados por lipemia com os CH de plasmas límpidos. Os PF lipêmicos foram separados e foi realizado registro por fotografia e dosagem dos triglicerídeos. Conforme o grau de turbidez os plasmas foram classificados como: ligeiramente turvos, moderadamente turvos, intensamente turvos ou leitosos. Conforme a concentração de triglicerídeos foram classificados como normal (<175 mg/dl), limítrofe (175 a 199 mg/dl), elevado (200 a 499 mg/dl) ou muito elevado (>500 mg/dl). Os respectivos CH foram avaliados durante o período de validade. Os experimentos nos CH foram realizados entre 1º e 10º, entre 11º e 22º, entre 23º e 34º e entre 35º e 42º dias de armazenamento. Foram avaliados: esterilidade, índices hematimétricos, ERO, TBARS, metemoglobina. Nos sobrenadantes dos CH foram avaliados: Na+, K+, Cl-, lactato, glicose, pH e grau de hemólise. Os experimentos também foram realizados com controles, CH de plasmas límpidos do mesmo dia de doação do grupo teste. Houve aumento da hemólise mais expressivo nos CH teste, demonstrando que a lipemia impacta negativamente na qualidade do CH durante o armazenamento. A partir dos resultados do estudo foram elaboradas estratégias para processamento, controle de qualidade, modificação e distribuição dos CH de doações com lipemia, garantindo a distribuição de um hemocomponente seguro e eficaz, minimizando descarte por hemólise e efeitos adversos à transfusão.The blood processing allows the patient receives only the blood component that he needs. The quality control starts with visual inspection and are evaluated: coloration, lipemia, clots and leaks. At the HEMEPAR, the main loss of fresh plasma (FP) is caused by lipemia. The lipemic F are discarded and the related red blood cell (RBC) remain in stock. During storage, RBCs go through the process of biochemical and morphological changes known as storage lesions, and the last one hemolysis. Therapeutic function and transfusion safety are compromised. Some authors report the relationship between lipemia and hemolysis. Lipemia is the turbid aspect of plasma, due to the presence of lipoproteins and is mainly related to the diet of the donor. The objective of this study was to compare the quality parameters of the RBCs from lipemic donations with RBC from clear donations. Lipemic FP were photographed and quantificated to triglycerides. According to the degree of turbidity the plasmas were classified as: slightly cloudy, moderately cloudy, intensely turbid or milky. Triglyceride concentrations were classified as normal (<175 mg / dl), borderline (175 to 199 mg / dl), high (200 to 499 mg / dl) or very high (> 500 mg / dl). The respective RBCs were evaluated during the period of validity. The CH experiments were performed between 1 and 10º, 11º and 22º, 23º and 34º and 35º and 42º days of storage. The following: sterility, hematimetric indexes, ROS, TBARS and methemoglobin were evaluated. In the supernatants Na +, K +, Cl-, lactate, glucose, pH and degree of hemolysis were evaluated. The experiments were also carried out with controls, RBC from clear donations of the same day of donation of the test group. There was an increase in hemolysis in the RBC test. It shows that lipemia negatively impacts the quality of RBC during storage. From the results of the study, were established strategies for processing, quality control, modification and distribution of RBC of donations with lipemic plasma to ensure the use of safe and effective blood product for transfusion.

Full textAbstract:
Vesijohtojen korroosion hidastamiseksi talousvesi tulee usein alkaloida ennen verkostoon pumppausta. Alkalointiprosessissa veden pH:ta nostetaan, mutta samalla vaikutetaan myös muihin veden ominaisuuksiin, kuten kovuuteen ja alkaliteettiin. Alkalointiin käytetään erilaisia emäksisiä kemikaaleja. Suomessa yleisimmät käytössä olevat alkalointikemikaalit ovat kalkki, lipeä ja sooda. Niillä on kuitenkin vaihtelevia vaikutuksia veden ominaisuuksiin, mikä vaikuttaa olennaisesti sopivan alkalointikemikaalin valintaan. Työn tavoitteena oli selvittää, millaisia vaikutuksia soodalla ja lipeällä on veden ominaisuuksiin, ja arvioida, miten kyseiset kemikaalit soveltuvat juomaveden alkalointiin. Työn pohjustukseksi on selvitetty myös talousveden käsittelyketju ja erityisesti alkalointiprosessi. Tuloksia on verrattu varsin yleiseen, kalkilla tehtävään alkalointiin. Tutkielma on tehty kirjallisuuskatsauksena aikaisempien tutkimusten ja alan kirjallisuuden pohjalta. Sooda ja lipeä ovat varsin yleisessä käytössä etenkin pienillä vedenpuhdistuslaitoksilla. Syynä suosioon on kemikaalien hyvä soveltuvuus prosessiin sekä syöttölaitteiston yksinkertaisuus. Käyttö on helppoa, eikä laitteisto vaadi suuria alkuinvestointeja. Veden kovuutta ei pystytä lipeällä tai soodalla nostamaan, mutta ongelman ratkaisemiseksi näiden rinnalla voidaan käyttää esimerkiksi kalkkikivialkalointia. Kumpikin kemikaali nostaa veden alkaliteettia, mutta soodalla sitä saadaan nostettua suhteellisesti enemmän kuin lipeällä. Mahdollisissa yliannostustilanteissa etenkin lipeä voi aiheuttaa vesijohtoverkoston käyttäjille terveysriskin. Tutkielman tuloksia voidaan soveltaa tyypillisen suomalaisen raakaveden käsittelyprosesseihin, ja ne voivat auttaa sopivimman alkalointikemikaalin valinnassa sekä vedenpuhdistusprosessien kehittämisessäCorrosion has been a big problem in water supply networks in Finland. To prevent corrosion, water purification plants have to alkalize the drinking water before pumping it to the network. In alkalization process, the pH of the water is raised. In the process the other features of water like hardness and alkalinity, are also affected. Alkalization process is accomplished with alkaline chemicals. The most used alkalization chemicals in Finland are lime, caustic soda and soda ash. All of them have different effects on the features of the water. This is a significant factor when the alkalization chemicals are chosen. The target in this thesis was to study what kind of effects caustic soda and soda ash have on water, and also estimate how well these chemicals suit to the alkalization process. To outline the issue, there is also explained the whole water purification process in this thesis. The results are compared with lime alkalization process, which is quite widespread in Finland. This thesis is a literature review and uses previous researches as a reference. Caustic soda and soda ash are quite common chemicals in smaller water purification plants. They suit well in alkalization process and require only cheap and simple facilities. There are also some problems with these chemicals. They do not raise the hardness of the water as lime does. To solve this problem, limestone can be used alongside these chemicals. Both caustic soda and soda ash raise the alkalinity of the water, but soda ash does it more effectively than caustic soda. In addition, especially caustic soda can cause health risks in potential overdose situations. The results of this thesis can be applied in purification processes of typical Finnish raw water. They can also help choosing the best alkalization chemical and developing water purification plants

Este estudo avaliou os níveis séricos de colesterol, triglicerídeos, glicose, frutosamina e leptina em cadelas obesas com e sem tumores de mama. Foram utilizados 60 caninos divididos em 4 grupos de 15 animais cada, sendo G1 e G2 os grupos controle. No grupo G1 animais com escore de condição corporal (ECC) ideal sem tumor de mama, no G2 animais com ECC ideal com tumor de mama, no grupo G3 animais com ECC elevado sem tumor de mama e no grupo G4 animais com ECC elevado com tumor de mama. Em geral todos os grupos de animais obesos apresentaram níveis séricos elevados estatisticamente significativos de triglicerídeos, colesterol, glicose, frutosamina e leptina quando comparado aos grupos controle. Animais obesos com tumor de mama (G4) apresentaram os níveis mais elevados de leptina, comprovados estatisticamente, comparado com todos os outros grupos. O presente estudo demonstra relação direta entre obesidade e dislipidemia, hiperglicemia e hiperleptinemia em cães. Adicionalmente, obesidade e hiperleptinemia podem estar associadas com aumento da predisposição ao desenvolvimento de tumores de mama. Esses achados representam importante contribuição uma vez que fornecem dados a uma área pobremente estudada em medicina veterinária. Os conhecimentos gerados neste estudo abrem novas perspectivas para o melhor entendimento de doenças, como a obesidade e os tumores de mama, cada vez mais frequentemente descritas em cães. Finalmente, os resultados apresentados são semelhantes ao descritos na mulher, o que potencializa a aplicação do conhecimento gerado em estudos de obesidade e tumores mamários em cães para o ser humano. ______________________________________________________________________________ ABSTRACT
This study evaluated cholesterol, tryglycerides, glucose, fructosamine and leptin blood profile in obese biches with and without mammary tumors. Sixty animals were divided in 4 groups each containing 15 biches. Groups G1 and G2 were the controls. The G1 was composed of animals with ideal body score condition (BSC) with no mammary gland tumor, G2 animals with ideal BSC with mammary gland tumos, G3 animals with high BSC (obese) and with no mammary gland tumor and G4 animals with high BSC and with mammary gland tumor. In general all groups represented by obese animals presented elevated tryglycerides, cholesterol, glucose, fructosamine and leptin blood levels statistically significant when compared with the control groups. Obese animals with mammary gland tumors (G4) had the highest levels of leptin, compared to all other groups. The current study demonstrates relashinship between obesity and dyslipedemia, glycemia and hyperleptinemia in dogs. In addition, obesity and hyperleptinemia might be associated with higher predisposition of mammary gland tumor development. These findings represent important contribution since they add data to a poorly studied field in veterinary medicine. This knowledge opens new perspectives for a better understanding of diseases, such as obesity and mammary gland tumors, which are currently more and more frequent in canines. Furthermore, the results presented here are similar to those described in the woman, which potencializes the application of the knowledge gained from studies of obesity and mammary gland tumors in dogs to the human being.

Full textAbstract:
Elevadas concentrações de tirglicerídeos (TAG) no período pós-prandial são associados com o desenvolvimento de doenças cardiovasculares (DCV), bem como são responsáveis por mais de 23% da mortalidade em mulheres na menopausa. O treinamento de força (TF) é uma intervenção não farmacológica impregada na prevenção e redução dos múltiplos fatores de risco para o desenvolvimento de DCV. O exercício de força realizado em alto volume vem sendo apresentado como estratégia efetiva na redução da lipemia pós-prandial (LPP) em jovens. No entanto, a comparação entre alto e baixo volume do TF não havia sido investigado. Por esse motivo, o objetivo deste estudo foi comparar a resposta aguda e de 11 semanas de TF realizado em baixo e alto volume na força dinâmica máxima, espessura muscular, gasto energético e perfil lipidico de mulheres pós-menopáusicas. Trinta e nove mulheres pós-menopausicas saudáveis e destreinadas (59,5±4,8 anos de idade, massa corporal 69,6±9,1 kg, estatura 157,9±7,2 cm; IMC 27,6±4,1 kg•m2; circunferência da cintura 76,1±9,7 cm; VO2pico 18,7±1,4 mL•kg•min) foram aleatóriamente distribuídas em três grupos que realizaram a sessão de exercícios de força em: baixo volume (uma série) (BVEF, n=12), alto volume (AVEF, n=14) e um grupo controle (GC, n = 13) que permaneceu em repouso. Os grupos experimentais (BVEF e AVEF) foram submetidos a uma sessão de exercícios de força (SEF), envolvendo oito exercícios. O grupo BVEF realizou uma série de 15 repetições máximas (RM), e o grupo AVEF realizou três séries de 15RM. Na SEF foram avaliados o gasto energético da sessão e o EPOC (excess post-exercise oxygen consumption). No teste de tolerancia oral a gordura (TTOG), ~16 horas após a SEF, todos os grupos receberam um refeição hiperlipidica a base de leite seguido por uma avaliação do perfil lipídico (colesterol total (CT), glicose (GLU), HDL, LDL e TAG) nos períodos basal, 1, 2, 3, 4 e 5 horas após o TTOG. Resultados: Não houve diferença significativa entre os grupos no perfil lipidico em nenhum dos períodos avaliados. O gasto energético total (SEF+EPOC) foi significativamente maior para AVEF em comparação ao BVEF (6,0±0,12 MJ e 3,1±1,1 MJ, respectivamente, p<0,001). No estudo com treinamento, foram avaliadas trinta e seis mulheres pós-menopáusicas com uma perda amostral de três mulheres, sendo estas submetidas a 11 semanas de TF. Os grupos AVEF e BVTF foram divididos em alto volume de treinamento de força (AVTF=13) e baixo volume de treinamento de força (BVTF=12), o GC (n=11) foi preservado. Neste estudo, todas as variáveis foram avaliadas pré e pós treinamento. Como resultados; nenhuma diferença significativa foi observada entre os grupos na LPP (mmol/L/5hs) para GLU, HDL, LDL e CT. Além disso, o AVTF vs BVTF foi significativamente maior após 11 semanas de TF nas variáveis taxa de oxidação de gordura (5,52±1,69 g/h vs 4,11±1,12 g/h), espessura muscular (VM, 21,4 ± 1,8 mm vs 18,4±1,2 mm e VL (22,3±1,2 mm vs 20,8±1,3 mm). Os pontos 0, 1, 2, 4 e 5 horas após TTOG para TAG e AUC de TAG (5,79±0,42 mmol/L/5hs vs 7,78±0,68 mmol/L/5hs), respectivamente, foram significativamente menores no grupo AVTF (p<0,05). Em conclusão, diferentes volumes de uma única sessão de exercícios de força não são capazes de reduzir a lipemia pós-prandial de mulheres pósmenopáusicas após teste de tolerância a gordura. Entretanto, os resultados desta investigação sugerem que a prescrição do alto volume de treinamento de força reduz a lipemia pós-prandial em mulheres pós-menopáusicas.Elevated concentrations of triglycerides (TAG) in the postprandial period are associated with the development of cardiovascular disease (CVD) and are responsible for over 23 % mortality in postmenopausal women. Resistance training (RT) is a non-pharmacological strategy to reduce multiple risk factors for developing CVD. The RT performed at high volume has been shown to be effective for the reduction of postprandial lipemia (PPL) in young people. However, the RT regular and systematic comparing high and low volume training had not been investigated. Therefore, the aim of this study was to compare the response subacute and 11 weeks of RT in low volume and high in strength, muscle thickness, energy expenditure and lipid profile of postmenopausal women. In article acute, thirty-nine postmenopausal women and healthy untrained (59.5±4.8 years, body mass 69.6±9.1 kg, height 157.9±7.2 cm, BMI 27,6±4.1 kg•m-2, waist circumference 76.1±9.7 cm; VO2peak 18.7±1.4 mL•kg-1•min-1) were randomly divided into three groups: group that conducted the exercise session strength at low volume (one set) ( LVSE, n=12), high volume (HVSE, n=14) and a control group (CG, n=13) who did not perform any exercise session. The experimental groups (LVSE and HVSE) held a session of strength exercises (SSE), involving eight exercises. In LVSE held a series of 15 repetitions maximum (RM), and the HVSE group performed three sets of 15RM, SSE were evaluated in the energy expenditure of the session and the EPOC (excess post -exercise oxygen consumption). In the test of oral fat tolerance (OGTT), ~16 hours of the SSE, all groups were given a high-fat meal and the milk, were evaluate; lipid profile (total cholesterol (TC), glucose (GLU), HDL, LDL and TAG) in times baseline, 1, 2, 3, 4 and 5 hours after an OGTT. Results: No significant difference between groups in lipid profile in any of the periods. Total energy expenditure (SSE+EPOC) was significantly higher compared to HVSE vs LVSE (6.0±0.12 MJ and 3.1±1.1 MJ, respectively, p<0.001). In the third study was evaluated thirty-six postmenopausal women, with a sample loss of three women who underwent 11 weeks of ST, and HVSE and LVSE groups were divided into high-volume strength training (HVST=13) and low volume strength training (LVST=12), GC (n=11) was preserved. In this study, all variables were assessed before and after 11 weeks os ST. Results: no significant difference was observed among groups in LPP (mmol/L/5 hours) to GLU, HDL, LDL and TC, also the HVSE versus LVSE was significantly greater after 11 weeks of ST for variables; rate fat oxidation, 5.52±1.69 g/h vs. 4.11±1.12g/h), muscle thickness (VM 21.4±1.2 mm versus 18.4±1.8 mm and VL, 22.3±1.2 mm versus 20.8±1.3 mm). In points 0, 1, 2, 4 and 5 hours after OGTT for TAG and TAG AUC (5.79±0.42 versus 7.78±0.68), respectively, were significantly lower in group AVTF (p<0.05). In conclusion, different volumes of a session of strength exercises do not reduce the subacutely postprandial lipemia in postmenopausal women after oral fat tolerance test. The results of this investigation suggest that the prescription of high volume strength training reduces postprandial lipemia in postmenopausal women.

Full textAbstract:
Low-fat, high-carbohydrate diets are recommended by various scientific bodies for the prevention of coronary heart disease. However, these diets increase postprandial lipaemia and so their net benefit for coronary heart disease risk has been the subject of vigorous debate. Exaggerated postprandial lipaemia has been implicated in the development of atherosclerosis. Previous research suggests that physical exercise improves triacylglycerol metabolic capacity. The present thesis investigated whether exercise, when simultaneously adopted with a high-carbohydrate diet, could prevent the augmentation of postprandial lipaemia observed with this dietary change.

Impaired clearance of triacylglycerol-rich lipoproteins contributes to atherogenesis. It can be argued that exercise may decrease the risk of atherosclerotic diseases through its potential to improve the metabolic capacity for triacylgycerol and hence, clearance of triacylglycerol-rich lipoproteins.

Background: High-fat meals (HFM) have been shown to increase postprandial lipemia (PPL) and inflammation. Acute exercise both pre and post-meal has been shown to attenuate PPL and inflammation. However, studies examining the interaction of HFMs and exercise on PPL and inflammation have used meal and exercise conditions more extreme than typical for average adults. The purpose of this study was to determine if moderate intensity exercise following a "true-to-life" HFM would attenuate PPL and inflammation. Methods: Participants were thirty-nine young adults (18-40 years) with no known metabolic disease. Inclusion criteria consisted of participants meeting physical activity guidelines of ≥ 150 min/week of moderate-to-vigorous physical activity or ≥ 75 min/week of vigorous activity, or < 30 min of planned physical activity per week. Participants were block randomized to EX or CON groups. Participants consumed a HFM of 10 kcal/kgbw. The EX group walked at 60% VO[subscript 2peak] to expend ≈ 5 kcal/kgbw beginning one-hour following the HFM. The CON group remained sedentary during the postprandial period. Blood samples were collected at baseline and 2, and 4hrs postprandially. Results: At baseline, there were no differences between EX and CON groups for any metabolic or inflammatory markers (p>0.05). Postprandial TRG increased ≈ 100% (p<0.001) in both groups, with no differences between groups. HDL concentrations decreased across time in both groups (p<0.001) with no differences between groups (p=0.338). HDL was higher in the EX group at 2hrs (p=0.047), but not 4hrs (p=0.135). IL-6 and TNF-α concentrations did not change over time with no differences between groups (p>0.05). The EX group increased sVCAM-1 from baseline to 4hr (p=0.003), while the CON group did not. Change in TRG was associated with change IL-6, IL-8, IL-10 and TNF-α from baseline to 2hrs when controlling for VO[subscript 2peak] and body fat%. No other associations were seen between change scores for TRG and inflammatory markers. Conclusions: Despite significant increases in PPL following a HFM, moderate intensity exercise in the postprandial period did not mitigate the PPL nor the inflammatory response to the HFM. These results indicate PPL and inflammation following a HFM are not directly related in a young, healthy population with low metabolic risk.

This thesis examines the influence of moderate exercise, attainable by a large percentage of the population, on lipoprotein metabolism in the fasted and postprandial states in normolipidaemic subjects. A cross-sectional study in middle-aged men and women (endurance athletes, recreational exercisers and sedentary controls) revealed that the more favourable fasted blood lipid profiles found in athletes were also apparent in recreational exercisers, with higher high density lipoprotein (HDL) cholesterol concentrations in female (1.94 v 1.57 mmol.l-1, p < 0.05), but not male (1.50 v 1.34 mmol.l-1 NS), recreational exercisers than sedentary controls. HDLz cholesterol concentrations were higher in both male (26%, p < 0.05) and female (42%, p < 0.01) recreational exercisers than controls.

Full textAbstract:
Coronary heart disease (CHD) remains the primary cause of death in the United Kingdom today and postprandial lipaemia (exaggerated elevation of the plasma triacylglycerol (TAG) concentration after intake of a fat-containing meal) is gaining recognition as an independent CHD risk factor. This thesis provides an overview of the effect that single bouts of exercise can exert on postprandial lipaemia. The conclusions from the experimental chapters within this thesis are that: prior moderate exercise reduces the lipaemia associated with moderate and high fat meals to a very similar extent in percentage terms; a single session of resistance exercise does not lower postprandial TAG concentrations in overweight, sedentary men, regardless of exercise intensity; ad libitum energy intake is not significantly increased on the morning after a brisk walk, with the exercise-induced lowering of lipaemia akin to percentage reductions from studies where fixed size meals were given; and aerobic exercise which lowers postprandial lipaemia, also increases postprandial hepatic portal vein and femoral artery blood flow. The general message from this thesis is that moderate-intensity aerobic exercise should be advocated as a strategy to lower cardiovascular disease risk, based on experimental evidence that postprandial lipaemia is consistently reduced after single bouts of brisk walking.

Full textAbstract:
Adipose tissue tumors (lipomas) frequently develop in patients with heterozygous germ line phosphatase and tensin homolog (PTEN) mutations. simvastatin has been demonstrated to exhibit antitumor effects, and so the aim of the present study was to assess the effects of simvastatin on the growth of human PTEN haploinsufficient lipoma cells. Whether the effects of simvastatin in lipomas are mediated via PTEN upregulation was also assessed. The results of the present study revealed that simvastatin treatment reduced cell viability and induced apoptosis in human lipoma cells. Furthermore, it was demonstrated that the expression of cellular PTEN mRNA and protein was increased following simvastatin stimulation. In addition, the phosphorylation of protein kinase B and downstream targets of mammalian target of rapamycin and 4E‑binding protein (4E‑BP)‑1 was attenuated. It was also demonstrated that simvastatin induced PTEN transcriptional upregulation by increasing peroxisome proliferator‑activated receptor (PPAR)γ expression. The small interfering RNA‑mediated knockdown of PPARγ abrogated the stimulatory effect of simvastatin on the PTEN protein, but did not influence apoptosis. The results of the present study suggest that simvastatin may be beneficial for patients with inoperable PTEN haploinsufficient lipomas.

Introdução: O extrato seco de Solanum melongena (berinjela) vem sendo utilizado pela população como um tratamento alternativo para dislipidemia. Ela é um vegetal rico em flavonóides que são antioxidantes polifenólicos encontrados nos alimentos. Estudos demonstram relação inversa entre o consumo de alimentos ricos em flavonóides e a mortalidade por doença arterial coronariana. O objetivo deste estudo foi avaliar o efeito da administração de cápsulas de extrato de berinjela no perfil lipídico de indivíduos saudáveis após um teste de sobrecarga lipídica via oral . Métodos: Após consentimento informado 58 voluntários saudáveis foram randomizados para receber cápsulas contendo 450 mg extrato seco de berinjela ou placebo. As cápsulas de berinjela ou placebo foram administradas na quantidade de duas cápsulas duas vezes ao dia durante 14 dias. No 14º dia os voluntários foram submetidos a um teste de sobrecarga lipídica, logo após a ingestão de 900 mg de extrato de berinjela ou placebo conforme randomização anterior. A análise nutricional da refeição continha 361 kcal, 22,5 g de gorduras totais, sendo destas 14,5g de gordura saturada e 251mg de colesterol. O perfil lipidico foi aferido em jejum nos dias 0 e 14 e neste último dia aferido em jejum e 2 horas após a sobrecarga lipidica. Resultados: Os níveis de trigliderídeos, expressos em mediana (amplitude interquartílica), encontrados nos voluntários do grupo berinjela foram 69mg/dl (51 - 102), 69 mg/dl (56 - 94) e 92 (64 - 120), antes do tratamento, no 14º dia pré e pós prandial, respectivamente. No grupo placebo os resultados foram 92mg/dl (77 - 128), 79 (60 - 108) e 98 (73 - 142), respectivamente. Não houve interação estatisticamente significativa entre tempo e grupo quanto ao nível de triglicerídeos (P=0,208). Também não foram encontradas diferenças nos valores de colesterol total (P=0,973), HDL colesterol (P=0,059) e LDL colesterol (P=0,611). Conclusão: Nossos resultados demonstram que a utilização de cápsulas de extrato seco de S. Melongena por 14 dias não produziu nenhum efeito no perfil lipidico em jejum e pós-prandial em indivíduos normais.Introduction: Dry Solanum melongena (eggplant) extract is being used by the population as an alternative treatment for dyslipidemia. It is a vegetable rich in flavonoids, which are polyphenol anti-oxidants found in foods. Studies reveal an inverse relationship between the consumption of foods rich in flavonoids and mortality from coronary artery disease. The objective of this study was to assess the effect of administering eggplant extract capsules on the lipid profile of healthy individuals after an oral lipid overload test. Methods: After informed consent, 59 healthy volunteers were randomized to take capsules containing 450 mg of dry eggplant extract or placebo. The eggplant or placebo capsules were administered in quantities of two capsules, twice a day, for 14 days. On the 14th day, the volunteers were submitted to a lipid overload test immediately after ingesting 900 mg of eggplant extract or placebo as per prior randomization. The nutritional analysis of the meal contained 361 kcal, 22.5 g of total fat, 14.5 g of which was saturated and 251mg of cholesterol. The lipid profile was checked during fasting on days 0 and 14 and on this last day it was checked during fasting and after a lipid overload. Results: Triglyceride levels, expressed as median (interquartile range), found in eggplant group volunteers were 69mg/dl (51 -102), 69 mg/dl (56 - 94) and 92 (64 - 120), before treatment, on the 14th day pre- and postprandial, respectively. In the placebo group, the results were 92mg/dl (77 - 128), 79 (60 - 108) and 98 (73 - 142), respectively. There was no statistically significant interaction between the time and the group as to triglyceride levels (P=0.208). No difference was found in total cholesterol (P=0.973), HDL cholesterol (P=0.059) and LDL cholesterol (P=0.611) levels either. Conclusion: Our results reveal that the use of dry S. Melongena extract capsules for 14 days did not produce any effect on the lipid profile during fasting and postprandial in normal individuals.

A lipemia pós-prandial (LPP) se caracteriza pelo aumento das concentrações de lipídeos sanguíneos, provocado por meio de refeição ou jejum e está diretamente relacionada com o sedentarismo e a formação da placa aterosclerótica. A adolescência é um período crítico no controle do peso e a inatividade física está associada com desenvolvimento de doenças cardiovasculares (DCV) prematuras. O exercício atua como um importante agente protetor contra o desenvolvimento e progressão de diversas doenças crônicas. Apesar dos efeitos do exercício sobre a LPP serem relativamente bem descritos, os seus efeitos sobre crianças e adolescentes têm sido negligenciados. Além disso, um dos aspectos intervenientes sobre a LPP é a intensidade de exercício. Dessa forma, o objetivo do estudo foi verificar os efeitos do exercício de intensidade média e alta na lipemia e glicemia pós-prandiais em adolescentes eutróficos saudáveis após refeição hiperlipídica. Treze adolescentes do sexo masculino, com idade entre 12 e 16 anos, foram selecionados e realizaram três protocolos: exercício de média intensidade (MI), exercício de alta intensidade (AI) e repouso (REP). No MI, os participantes pedalaram durante 45 minutos a 10% abaixo do 2° limiar ventilatório, seguidos de 180 minutos de repouso. No AI, os participantes pedalaram a 10% acima do 2° limiar ventilatório até alcançarem o mesmo gasto energético do MI. No REP, os participantes permaneceram em repouso durante todo o período. Foi fornecida uma refeição rica em gordura após cada protocolo. Amostras de sangue foram coletadas nos tempos 0 (jejum), 45min (logo após exercício), 105min (1h após a refeição), 135min, 165min, 195min e 225min em cada protocolo. Os níveis de triglicerídeos (TG), colesterol total (CT), HDL, LDL e glicose foram mensurados. Não houve diferenças entre as condições em relação aos níveis de CT, HDL, LDL e glicose. Foi encontrada uma redução significativa (p<0,05) nos níveis de TG (mg/dl) na condição MI quando comparado ao REP e AI no minuto 105 (70,1 + 10,3 vs. 92,2 + 32,4 e 82,2 +10,4) e 135 (68,4 + 14,4 vs. 97,3 + 15,6 e 91,54 + 24,9), respectivamente, e no minuto 165 entre REP e MI (103,14 + 24,2 vs. 82,4 + 18,8). A área sob a curva de TG (mg/dl/min) no MI foi 17,19% significativamente inferior quando comparado ao REP (16.437 vs 19.848) e 12,82% inferior quando comparado ao AI (16.437 vs 18.856). Em conclusão, o exercício de MI mostrou-se eficaz na redução dos triglicerídeos pós-prandiais em adolescentes saudáveis, quando comparado ao repouso e ao exercício de AI.Postprandial lipemia (PPL) is characterized by increased concentrations of blood lipids, caused by meal or fasting and is directly related to a sedentary lifestyle and the formation of atherosclerotic plaque. Adolescence is a critical period in weight and physical inactivity is associated with premature cardiovascular disease (CVD) development. Exercise acts as an important protective mediator against the development and progression of several chronic diseases. Despite the effects of exercise on LPP are relatively well described, its effects on children and adolescents have been neglected. Moreover, one of the factors on aspects LPP is the intensity of exercise. Thus, the aim of this study was to investigate the effects of exercise of medium and high intensity on postprandial lipemia and glycemia in healthy normal adolescents after a high fat meal. Thirteen male adolescents, aged between 12 and 16 years, were selected and performed three protocols: exercise of moderate intensity (MI), high-intensity exercise (HI) and rest (RES). In MI, participants cycled for 45 minutes at 10% below 2nd ventilatory threshold, followed by 180 minutes of rest. In HI, participants cycled at 10% above the 2nd ventilatory threshold in order to achieve the same energy expenditure MI. RES, the participants remain at rest during the entire period. A high fat meal was provided after each protocol. Blood samples were collected at 0 (fasting), 45min (after exercise), 105min (1h after the meal), 135min, 165min, 195min and 225min in each protocol. Triglycerides (TG), total cholesterol (TC), HDL, LDL and glucose were measured. There were no differences between conditions in relation to the levels of TC, HDL, LDL and glucose. A significant reduction (p <0.05) was found in the levels of TG (mg / dL) in the condition MI when compared to the REP and HI at 105 minutes (70.1 ± 10.3 vs. 92.2 + 32.4 and 82.2 +10.4) and 135 (14.4 vs. 68.4 +. 97.3 + 15.6 + 24.9 and 91.54), respectively, and at 165 minutes between REP and MI (24.2 vs 103.14 +. 82.4 + 18.8). The area under the curve of TG (mg / dl / min) in MI was 17.19% significantly lower when compared to REP (16,437 vs 19,848) and 12.82% lower when compared to HI (16,437 vs 18,856). In conclusion, the MI exercise was effective in reducing the postprandial triglyceride levels in healthy adolescents, when compared at rest and during HI exercise.

O exercício físico tem sido indicado na prevenção do aumento da lipemia pós-prandial (após o consumo de uma refeição hiperlipídica). O objetivo deste estudo foi comparar o efeito de duas sessões de exercício físico concorrente (tradicional e em circuito) na curva lipêmica de sujeitos submetidos à refeição hiperlipídica. Onze sujeitos do sexo masculino, familiarizados com treinamento concorrente (IMC 25,50 ± 2,10kg/m²) com idade média de 28,1 + 4,7 anos participaram da realização de um experimento composto por 2 dias consecutivos. No dia 1, os sujeitos realizavam um dos três protocolos randomizados: 1) CON - repouso; 2) CT - exercício concorrente tradicional (30 minutos de exercícios de força em circuito, seguidos de 20 min de exercício aeróbico a 70% do consumo máximo de oxigênio); 3) CC - exercício concorrente em circuito (50 minutos de exercícios de força e “tiros” de 2 min na esteira a 70% do consumo máximo de oxigênio, sob forma de circuito). No dia 2, 12h após a realização dos protocolos, os sujeitos consumiam uma refeição hiperlipídica. As coletas de sangue para análise de Triglicerídeos (TG), Glicose e Insulina foram realizadas no momento basal e de 1 à 5h após o consumo da refeição. O CT e o CC apresentaram menores níveis de TG comparado ao CON na hora 1 (p<0,05) e o CT também apresentou diferença do CON na hora 4 (p<0,05). Em relação à área abaixo da curva (AUC) de TG, houve diferença entre os protocolos CT e CC em comparação ao CON (p<0,05). Não foram encontradas diferenças entre os protocolos para Glicose. Em relação à AUC de Insulina, houve diferença entre os protocolos CT e CC em comparação ao CON (p<0,05), sendo que o CC apresentou diferença para maior em relação ao CT (p<0,05). Em conclusão, tanto o exercício CT quanto o CC são eficazes para atenuar a lipemia e a insulina pós-prandiais, sendo o CC ainda mais eficaz na atenuação da insulina.The physical exercise has been shown to prevent the increase of postprandial lipemia (after consuming a high-fat meal). The objective of this study was to compare the effect of two concurrent sessions of exercise (traditional or circuit) in lipaemic curve of subjects who underwent fat meal. Eleven male subjects, familiar with concurrent training (BMI 25.50 ± 2,10kg/m²) with average age of 28.1 ± 4.7 years participated in the realization of an experiment in 2 consecutive days. On day 1, the subjects performed one of three randomized protocols: 1) CON - break; 2) CT - traditional concurrent exercise (30 minutes of circuit strength exercises, followed by 20 minutes of aerobic exercise at 70% of maximal oxygen uptake; 3) CC - concurrent exercise circuit (50 minutes of strength exercises and "bouts" of 2 min on the treadmill at 70% of maximal oxygen consumption, as circuit. On day 2, 12 hours after the completion of the protocols, the subjects consumed a high-fat meal. The blood samples for analysis of triglycerides (TG), glucose and insulin were performed at baseline and 1 to 5 hours after consumption of the meal. The TC and CC showed lower levels of TG compared to the CON 1 hour (p <0.05) and CT also showed difference in the CON 4 hours (p <0.05). In relation to the area under the curve (AUC) of TG there was a difference between TC and CC protocols compared to the CON (p <0.05). No differences were found between the protocols for glucose. Regarding Insulin AUC there was a difference between TC and CC protocols compared to the CON (p <0.05), considering that the CC showed a difference from the CT (p <0.05). In conclusion, both the CT and CC exercises are effective to mitigate lipemia and postprandial insulin, being the CC more efficient in insulin attenuation.

Full textAbstract:
Hyperlipidemia caused by a diet high in saturated fat can lead to visceral fat weight gain, obesity, and metabolic syndrome. Being over-weight from visceral fat has been linked to increased risk of developing most age-related diseases and disability, along with a lower income potential and quality of life. However, researchers are just beginning to understand the biological mechanisms that regulate the conversion of excess calories into visceral fat storage rather than glycogen or muscle. Epidemiological studies have repeatedly shown a comorbid association between age-related diseases involving hyperlipemia and circulating levels of uric acid, but not a direct association. This study utilized archival data from 31 healthy, middle-aged adults, who participated in a randomized, double-blind, crossover clinical trial on blood markers of lipidemia and inflammation following a high saturated fat (HSF) verses a "healthy" polyunsaturated fat (PUFA) meal. This primary study was conducted and funded by the National Institute on Aging. A secondary analysis of this data using Pearson's correlation with least squares (2-tailed) regression modeling found that when stratified by gender, baseline uric acid level was an independent and significant predictor of the lipemic response from the HSF, but not the PUFA meal. The linear regression plots indicated that males with uric acid levels above 4.5, and females above 3.0 mg/dL, had a progressively increased lipemic response to the HSF meal. The public health utility of this finding may include the clinical use of the gender-specific linear regression plots of uric acid values to identify and advise individuals at risk for hyperlipidemia from a diet high in saturated fats.

Obesity and asthma often coexist in the same people. Both are characterized by the presence of low-grade systemic inflammation. A high-fat diet may contribute to concurrent development of both conditions by promoting a pro-inflammatory postprandial environment leading to a transient accumulation of blood lipids (postprandial lipemia; PPL) and acute airway inflammation. Previous results from our lab have shown an ~20% increase in airway inflammation two hours after consuming a high-fat meal (HFM) that was significantly associated with increased plasma triglycerides. While acute exercise has been shown to attenuate PPL, it is unknown whether these protective effects will translate to reduced airway inflammation after a high-fat meal. PURPOSE: To determine the effects of an acute bout of exercise on airway inflammation after a HFM. We tested the hypothesis that an acute bout of exercise 12 hours before a high-fat meal would protect against subsequent airway inflammation in healthy men and would be related to the decreased PPL and systemic inflammatory markers. METHODS: In a randomized cross-over study, 12 healthy college-aged men consumed a HFM (1g fat/1kg body weight) 12 hours following exercise (EX; 60 min at 60% VO2max) or without exercise (CON). Exhaled nitric oxide (eNO; measure of airway inflammation), blood lipid profiles (venous sample; total cholesterol, HDL, LDL, triglycerides, glucose), inflammatory markers (hsCRP, TNF-[alpha], IL-6) and pulmonary function tests (PFT) (forced expiratory volume in 1-s,forced vital capacity, forced expiratory flow at 25-75% of vital capacity) were measured pre-HFM, two hours, and four hours post-HFM. RESULTS: Baseline eNO was not different (p>0.05) between trials. eNO increased (p<0.05) post HFM at two hours in the both CON and EX conditions. eNO between trials was not different (p>0.05). Triglycerides were significantly increased two and four hours post HFM but were not different (p>0.05) between conditions. There was no relationship (p>0.05) between eNO and triglycerides or systemic inflammatory markers for any time point in either condition. Pulmonary function did not differ (p>0.05) between any condition. CONCLUSION: These results demonstrate that an acute bout of moderate intensity exercise 12 hours before a HFM does not attenuate postprandial airway inflammation or lipemia in healthy college-aged men.

La contribution des lipides alimentaires à la lipémie postprandiale au cours de repas successifs a été peu explorée. Dans l'étude n°1, six sujets sains ont ingéré 2 repas mixtes (déjeuner et dîner). Les lipides du déjeuner contribuaient à la lipémie post-dîner malgré l'intervalle de 7h entre les 2 repas. Dans l'étude n°2, neuf sujets sains ont ingéré un petit déjeuner à 7h30 ainsi qu'un déjeuner (12h00). L'enrichissement en palmitate des TG montrait une participation des lipides du petit déjeuner (suivis par scintigraphie) étaient en partie retenus dans l'estomac et l'intestin grêle avant le déjeuner. Le déjeuner mobilisait ces lipides, par accélération de la vidange intestinale. En conclusion, les lipides ingérés au cours d'un repas contribuent à la lipémie du repas suivant même lorsque l'intervalle entre les deux repas est relativement long (7h). La vidange intestinale est un élément important de la régulation des flux d'entrée plasmatique des chylomicrons lors de repas successifsContribution of dietary fat to postprandial lipemia during sequential meals has not been extensively investigated. In the first study, six healthy subjects ingested 2 mixed meals (lunch and dinner). Lipids ingested at lunch contributed to post-dinner lipemia, despite the relatively long lasting interval between meals (7h). In the second study, nine healthy subjects ingested subsequently a breakfast (7:30 am) and a lunch (12:00 am). Dietary lipids ingested at breakfast were labelled with palmitate and Lipiodol. Palmitate enrichment confirmed the contribution of fat ingested at breakfast to post-lunch lipemia. Lipiodol dynamics, followed in vivo by scintigraphic imaging, showed that fat ingested at breakfast was retained in part within the gut at lunch time and mobilized following lunch ingestion. In conclusion, dietary lipids ingested at a first meal contribute to subsequent postprandial lipemia, despite a 7h interval between meals. Gastric emptying influences the rate of entry of lipids into the circulation during sequential meals

Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorNitric oxide (NO) is a reactive free radical, that acts as a messenger molecule, mediating several functions, including vasodilation, platelet aggregation inhibition, neurotransmission, antimicrobial and antitumor activities. In several pathological conditions, NO is associated with increased circulatory concentrations of cytokines and endotoxins in inflammatory processes in especially. Because this radical to have a short half-life, its determination is difficult, therefore, measurement of metabolites nitrite/nitrate (NOx) is most often used to evaluate NO production. The objective of this study the effect of pre-analytical interferences been investigating on the NOx and determine the limits of urinary and serum reference for a healthy population. In the simulation of bilirubin, lipemia and hemolysis on serum samples, we evaluated the pre-analytical interference in the measurement of NOx All bilirubin concentrations used (9, 19, 38, 75, 150 and 300 mg /L), Intralipid® (0.67, 1.25, 2.5, 5 and 10 g/L) and hemoglobin (0.5, 1.0, 2.0, 4.0 and 5.0 g/L) resulted in a difference between the original amount of NOx being checked greater than 10 percent %, thus, considered an analytical interference. The reference limits were evaluated following the recommendations of the International Federation of Clinical Chemistry (IFCC), and urinary values of 46.1 mmol / L to 1533.0 mmol/L, and serum values 56.8 mmol/L at 340, 3 mmol/L for a presumably healthy population. Thus, we conclude that bilirubin, lipemia and hemolysis interfere with the measurement of serum activity of NOx.

O óxido nítrico (NO) é um radical livre reativo, que age como uma molécula mensageira, mediando diversas funções, incluindo vasodilatação, inibição da agregação plaquetária, neurotransmissão, atividades antimicrobianas e antitumorais. Em várias condições patológicas, o NO está associado com o aumento da concentração circulatória de citocinas e endotoxinas especialmente em processos inflamatórios. Pelo fato deste radical possuir uma meia-vida curta, a sua determinação torna-se difícil e, consequentemente, a mensuração de seus metabólitos nitrito/nitrato (NOx) é mais frequentemente utilizado para avaliar a produção de NO. Assim, o objetivo deste estudo foi investigar o efeito de interferentes pré-analíticos sobre os níveis de NOx, bem como determinar os limites de referência urinária e sérica para uma população saudável. Na simulação da icterícia, lipemia e hemólise em amostras séricas, avaliou-se a interferência pré-analítica na mensuração do NOx. Todas as concentrações utilizadas de bilirrubina (9, 19, 38, 75, 150 and 300 mg/L), de Intralipid® (0,67; 1,25; 2,5; 5 e 10 g/L) e de hemoglobina (0,5; 1,0; 2,0; 4,0 e 5,0 g/L) resultaram em uma diferença do valor original de NOx, sendo verificada uma porcentagem maior que 10%, sendo assim, considerada uma interferência analítica. Os limites de referência foram avaliados seguindo recomendações da International Federation of Clinical Chemistry (IFCC), sendo os valores urinários de 46,1 μmol/L a 1533,0 μmol/L, e os valores séricos 56,8 μmol/L a 340,3 μmol/L para uma população saudável. Também foi possível concluir que a bilirrubina, lipemia e hemólise causam interferência na mensuração da concentração sérica do NOx.
