ABSTRACT

Las variantes de ANGPTL3 con pérdida de función están asociadas con efectos beneficiosos sobre el metabolismo lipídico y de carbohidratos y con riesgo reducido de enfermedad coronaria. Los cambios beneficiosos en los parámetros lipídicos que se obtienen con la inhibición de ANGPTL3 junto con la reducción en aterosclerosis que se observa en modelos animales y en estudios epidemiológicos de genética humana hacen de ANGPTL3 un nuevo objetivo terapéutico para prevenir las enfermedades cardiovasculares. Dos estrategias novedosas han surgido para inhibir esta proteína: un anticuerpo monoclonal y un oligonucleótido antisentido, con capacidad para reducir tanto el colesterol como los triglicéridos plasmáticos en forma notoria. Aunque el horizonte es promisorio, todavía no sabemos si los efectos de una variante presente desde el comienzo de la vida serán reproducidos por la inhibición de esta proteína que se realiza más tarde en la vida a través de una intervención farmacológica.

Loss-of-function ANGPTL3 variants are associated with beneficial effects on carbohydrate and lipid metabolism, and reduced risk of coronary heart disease. The beneficial changes in lipid parameters obtained by ANGPTL3 inhibition together with atheroprotection observed in animal models and in epi-demiological studies of human genetics make ANGPTL3 a new therapeutic target to prevent cardiovascular diseases. Two novel strategies have emerged to inhibit this protein: a monoclonal antibody and an antisense oligonucleotide, with the ability to significantly lower plasma cholesterol and triglycerides. Although the horizon is promising, we still do not know if the effects of a variant present from the beginning of life will be reproduced by the inhibition of this protein that takes place later in life through a pharmacological intervention.

ABSTRACT

Introdução: Usuários do sistema de saúde com doenças crônicas não transmissíveis devem estar em acompanhamento constante para evitar complicações em seu estado de saúde. Objetivo: Analisar os indicadores laboratoriais de saúde em usuários de uma Unidade Básica de Saúde com e sem o diagnóstico para a diabetes e hipertensão. Métodos: A amostra foi de 231 usuários de uma unidade básica de saúde da cidade de Santarém-PA, maiores de idade, que foram agrupados em pacientes com DM/HAS (DM/HAS; n=144), e sem o diagnóstico para DM/HAS (AUS; n=87). As coletas envolveram informações socioeconômicas, clínicas e laboratoriais. Os dados foram tratados com estatística descritiva e inferencial, adotando-se p<0.05. Resultados: Tanto no DM/HAS como no AUS predominou o sexo feminino, estado civil casado, com vínculo empregatício, cor de pele parda, com 4-7 anos de estudo, renda de 1-2 salários, não tabagistas, não etilista e faixa etária de 38-77 anos. A HAS foi a doença mais presente de forma geral, bem como por sexo. Identificou-se no DM/HAS valores menores para a taxa de filtração glomerular (TFG) e maiores valores para a glicemia, triglicerídeos, colesterol total, LDL-c e não HDL-c. Conclusão: De acordo com a proposta desenvolvida, destaca-se que os usuários com DM/HAS apresentam associação positiva para valores alterados de glicemia, colesterol total, não HDL-c, triglicerídeos, TFG e para a presença da síndrome metabólica e risco cardiovascular moderado/alto.


Introduction: Users of the health system with chronic non-communicable diseases must be constantly monitored to avoid complications in their health status. Objective: Analyze laboratory health indicators in users of a Basic Health Unit with and without a diagnosis for diabetes and hypertension. Methods: The sample consisted of 231 users of a basic health unit in the city of Santarém-PA, all of them of age, grouped into patients with DM/SAH (DM/SAH; n=144), and without the diagnosis for DM/SAH (ABS; n=87). The collections involved socioeconomic, clinical, and laboratory information. The data were treated with descriptive and inferential statistics, adopting p <0.05. Results: In both DM/SAH and ABS groups, there was a predominance of female individuals, married status, employed, brown skin color, with 4-7 years of study, income of 1-2 salaries, non-smokers, non-alcoholic drinkers, and aged between 38-77 years. SAH was the most common disease in general, as well as when analyzing by gender. Lower values for the glomerular filtration rate (GFR) were identified in the DM/SAH and higher values for the glycemia, triglycerides, total cholesterol, LDL-c, and non-HDL-c. Conclusion: According to the proposal of this paper, it is noteworthy that users with DM/SAH have a positive association for altered values of blood glucose, total cholesterol, non-HDL-c, triglycerides, GFR, and for the presence of metabolic syndrome and moderate/high cardiovascular risk.

ABSTRACT

The present study aimed to evaluate increasing levels of fish waste oil in diets for laying hens on serum biochemistry profile. 192 Hisex White laying hens at 29 weeks of age were used, with water and food ad libitum. The experimental design was completely randomized consisting of eight treatments corresponding to the inclusion levels of fish waste oil (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 and 3.5%) in the diets, with four replicates of six birds each. Data collected were subjected to polynomial regression at 5% of significance. Significant differences (P<0.05) were observed in triglycerides, glucose, total cholesterol, and uric acid. These parameters presented a decrease when hens fed diets with higher level of fish waste oil. The results of the present study indicated that the inclusion of fish waste oil caused a significant effect in the serum biochemical profile of laying hens, especially in glucose, triglycerides, total cholesterol, and uric acid concentrations. The inclusion level of 3.5% of fish waste oil caused larger disequilibrium in the serum biochemical profile of laying hens.(AU)


O presente estudo objetivou avaliar os níveis crescentes de óleo de resíduo de pescado em dietas para poedeiras leves sobre o perfil bioquímico sérico. Foram utilizadas poedeiras Hisex White com 29 semanas, com água e ração ad libitum. O delineamento experimental foi inteiramente ao acaso, consistindo de oito tratamentos correspondentes aos níveis de inclusão de óleo de resíduo de pescado (0; 0,5; 1,0; 1,5; 2,0; 2,5; 3,0 e 3,5%) nas dietas, com quatro repetições de seis aves cada. Os dados coletados foram submetidos à regressão polinomial a 5% de significância. Diferenças significativas (P<0,05) foram observadas nas concentrações de triglicerídeos, glicose, colesterol total e ácido úrico. Esses parâmetros apresentaram uma diminuição quando as aves se alimentaram com rações contendo maior nível de óleo do resíduo de pescado. Os resultados do presente estudo indicaram que a inclusão de óleo do resíduo de pescado acarretou um efeito significativo no perfil bioquímico sérico de poedeiras, principalmente nas concentrações de glicose, triglicerídeos, colesterol total e ácido úrico. O nível de inclusão de 3,5% do óleo do resíduo de pescado acarretou maior desequilíbrio no perfil bioquímico sérico das poedeiras.(AU)

ABSTRACT

BACKGROUND@#Remnant-like particle cholesterol (RLP-C) is highly atherogenic, which is associated with atherosclerosis. However, RLP-C has not been routinely measured in the clinical practice. We estimated RLP-C levels using conventional lipid profiles and examined the association between estimated RLP-C and related factors including nutrient intake.@*METHODS@#This study was performed in Uku town, Nagasaki prefecture, Japan in 2019. A total of 225 subjects were enrolled and directly measured RLP-C levels. Estimated RLP-C levels were defined as the following formula [total cholesterol - (LDL-cholesterol) - (HDL-cholesterol)]. Multivariate analyses were used to assess the relationship between estimated RLP-C and atherogenic factors. We calculated cut-off values on dichotomized RLP-C (< 7.5 mg/dL vs. ≥ 7.5 mg/dL) by receiver operating characteristic (ROC) curve.@*RESULTS@#The mean values of directly measured RLP-C levels and estimated RLP-C were 4.0 mg/dL and 16.4 mg/dL, respectively. In the multiple stepwise linear regression analysis, directly measured and estimated RLP-C levels were independently and commonly associated with apolipoprotein E, triglycerides, and vegetable fat intake (inversely). Using ROC curves, we found the cut-off value of estimated RLP-C was 22.0 mg/dL.@*CONCLUSION@#We demonstrated that the estimated RLP-C levels using conventional lipid profiles may substitute for directly measured RLP-C and these levels were independently and inversely associated with vegetable fat intake in the community-dwelling Japanese population.

ABSTRACT

INTRODUCCIÓN: Las dislipidemias favorecen la formación precoz de placas ateroscleróticas, aumentando el riesgo de enfermedades cardiovasculares (ECVs). La Actividad Física (AF) es un factor protector de ECVs, por lo que el objetivo de este trabajo fue evaluar la asociación entre AF medida objetivamente y dislipidemias en población pediátrica. METODOLOGÍA: La AF fue evaluada en 159 niños (9-13 años) de la Región de La Araucanía a través de acelerometría (ActiGraph GT3X+). Por este medio se estimó el porcentaje de AF moderada a vigorosa (AFMV) y el de conducta sedentaria (CS). Sujetos con ≥60 min de AFMV se consideraron físicamente activos según recomendación de la Organización Mundial de la Salud (OMS). Individuos con %CS>75° percentil fueron considerados sedentarios. El perfil lipídico fue determinado usando métodos convencionales. Fueron calculados índices de aterogenicidad TG/cHDL e índice de aterogenicidad del plasma (IAP). RESULTADOS: 37,1% presentó dislipidemia, 8% hipercolesterolemia, 19,5% hipertrigliceridemia, 6,3% cLDL elevado y 25,2% cHDL disminuido. Solo un 9,4% fueron considerados físicamente activos de acuerdo a la recomendación de la OMS. En los sujetos físicamente activos no hubo caso de dislipidemias (p= 0,032) y tampoco bajos niveles de cHDL (p= 0,013). El %AFMV estaba reducido en sujetos con cHDL bajo y se correlacionó positivamente con HDL-c (r= 0,157, p=0,048). Además, el %AFMV se correlacionó con menores valores de TG/cHDL (r= -0,193, p=0,015) e IAP (r= -0,214, p=0,006). Si bien el comportamiento sedentario no estuvo asociado con riesgo de dislipidemias, el %CS se correlacionó positivamente con niveles de glucosa (r= 0,159, p=0,044) y HOMA-IR (r= 0,178, p=0,037) y negativamente con Quicki (r= -0,160, p=0,044). CONCLUSIONES: Los hallazgos sugieren que la AF se correlaciona a menor frecuencia de dislipidemias y la práctica de AFMV aumentaría los valores de HDL-c y reduciría los índices aterogénicos, por lo que promoverla puede significar disminuir el riesgo de ECVs en nuestra población. Además, la CS se relaciona con un aumento en valores de glucosa e índices de resistencia insulínica en escolares de la Región de La Araucanía.


Dyslipidemias cause early formation of atherosclerotic plaque, increasing the risk of cardiovascular diseases (CVD). Physical Activity (PA) is a protective factor against CVDs. The aim of this study is to evaluate the association between objectively measured PA with dyslipidemias in a pediatric population. METHOD: The PA was evaluated in 159 children (9-13 years old) from Región de La Araucanía using accelerometry (ActiGraph GT3X +). The percentage of moderate to vigorous PA (MVPA) and sedentary behavior (SB) were estimated. Subjects with ≥60 min of MVPA were considered physically active according to the recommendation of the World Health Organization (WHO). Individuals with %SB >75th percentile were sedentary. The lipid profile was determined using conventional methods. TG/HDL-C ratio and atherogenic index of plasma (AIP) were calculated. RESULTS: 37.1% presented dyslipidemia, 8% hypercholesterolemia, 19.5% hypertriglyceridemia, 6.3% elevated LDL-C and 25.2% decreased HDL-C. Only 9.4% were physically active according to the WHO recommendation. In physically active subjects where no cases of dyslipidemias (p =0.032) and no low HDL-C (p = 0.013). The %MVPA was reduced in subjects with low HDL-C and positively correlated with HDL-c (r = 0.157, p = 0.048). In addition, %MVPA was correlated with lower TG / HDL-C values (r = -0.193, p = 0.015) and AIP (r = -0.214, p = 0.006). SB was not associated with risk of dyslipidemia, % SB was positively correlated with glucose levels (r = 0.159, p = 0.044) and HOMA-IR (r = 0.178, p = 0.037) and negatively with Quicki (r = -0.160, p = 0.044). CONCLUSIONS: Our results suggested that PA is it correlates to a lower frequency of dyslipidemia and the practice of MVPA would increase HDL-c values and reduce atherogenic index, promoting it may been reducing the risk of CVDs in our population. In addition, the SB is related to an increase in glucose values and insulin resistance index in schoolchildren in Región de La Araucanía.

ABSTRACT

In this eight-year retrospective study, we evaluated the associations between climatic variations and the biological rhythms in plasma lipids and lipoproteins in a large population of Campinas, São Paulo state, Brazil, as well as temporal changes of outcomes of cardiovascular hospitalizations. Climatic variables were obtained at the Center for Meteorological and Climatic Research Applied to Agriculture (University of Campinas - Unicamp, Brazil). The plasma lipid databases surveyed were from 27,543 individuals who had their lipid profiles assessed at the state university referral hospital in Campinas (Unicamp). The frequency of hospitalizations was obtained from the Brazilian Public Health database (DATASUS). Temporal statistical analyses were performed using the methods Cosinor or Friedman (ARIMA) and the temporal series were compared by cross-correlation functions. In normolipidemic cases (n=11,892), significantly different rhythmicity was observed in low-density lipoprotein (LDL)- and high-density lipoprotein (HDL)-cholesterol (C) both higher in winter and lower in summer. Dyslipidemia (n=15,651) increased the number and amplitude of lipid rhythms: LDL-C and HDL-C were higher in winter and lower in summer, and the opposite occurred with triglycerides. The number of hospitalizations showed maximum and minimum frequencies in winter and in summer, respectively. A coincident rhythmicity was observed of lower temperature and humidity rates with higher plasma LDL-C, and their temporal series were inversely cross-correlated. This study shows for the first time that variations of temperature, humidity, and daylight length were strongly associated with LDL-C and HDL-C seasonality, but moderately to lowly associated with rhythmicity of atherosclerotic outcomes. It also indicates unfavorable cardiovascular-related changes during wintertime.

ABSTRACT

SUMMARY: The objective of this study was to describe the effects of monosodium glutamate on the collagen of the parotid gland in an obesity model. 18 newborn male Sprague Dawley rats were used (first control group; second group of MSG1: 4 mg/g of monosodium glutamate weight, 5 doses, and third group of MSG2: 4 mg/g of monosodium glutamate, 5 doses, maintained for 8 and 16 weeks respectively). The content and type of collagen were analyzed, in addition to the levels of cholesterol, glucose, triglycerides and uric acid. Monosodium glutamate produced an increase in the obesity rates of the MSG2 group, in addition to an increase in blood cholesterol, glucose and uric acid levels compared to the control group. Type III collagen in the MSG2 group showed a statistically significant increase. Monosodium glutamate induced obesity, in addition to an increase in type III collagen fibers.

ABSTRACT

SUMMARY OBJECTIVES Individuals living with HIV seem to be more prone to changes in the redistribution of body fat, characterized as lipodystrophy, which may occur in conjunction with metabolic diseases. In the present study, such impacts were assessed in adults with and without HIV and associated with the time of virus diagnosis and treatment with antiretroviral. METHODS A cross-sectional study with 123 adults, in which 87 had HIV and 36 without HIV, of both sexes, in outpatient follow-up at the Specialized Care Service (SAE) in Macaé-RJ. The following were made: 1) Alteration in body fat distribution, measured by anthropometric parameters and self-reported lipodystrophy; 2) Biochemical profile; 3) Association between HIV diagnosis time and antiretroviral treatment. RESULTS 54.47% (n = 67) males, 45.52% (n = 56) females, mean age 37 years. Of these 87 were people living with HIV, 29% (n = 25) had self-reported lipodystrophy, mean time of virus infection, and antiretroviral treatment (5.80 ± 4.56 and 5.14 ± 3.82 years), respectively. Patients with self-reported lipodystrophy had a greater change in body fat distribution between 3-6 years of HIV diagnosis and a negative cholesterol profile. The antiretroviral treatment time influenced total cholesterol and triglycerides, even for patients without self-reported lipodystrophy, with a further nine years under treatment. CONCLUSION In this study, the negative cholesterol profile was mainly related to antiretroviral treatment time, even for patients without self-reported lipodystrophy, and changes in body fat distribution, measured by anthropometry, was especially associated with time for HIV infection in those with lipodystrophy self-reported.


RESUMO OBJETIVOS Indivíduos vivendo com HIV parecem mais propensos às alterações na redistribuição da gordura corporal, caracterizada como lipodistrofia, podendo acontecer em conjunto com as metabólicas. No presente estudo avaliaram-se tais impactos em adultos com e sem HIV e se associou ao tempo de diagnóstico do vírus e tratamento com antirretroviral. MÉTODOS Estudo tipo transversal, com 123 adultos, no qual 87 tinham HIV e 36 sem HIV, de ambos os sexos, em seguimento ambulatorial no Serviço de Atendimento Especializado (SAE) em Macaé - RJ. Foram feitos: 1) Alteração na distribuição da gordura corporal, mensurados por parâmetros antropométricos e lipodistrofia autorreferida; 2) Perfil bioquímico; 3) Associação entre tempo diagnóstico do HIV e tratamento com antirretroviral. RESULTADOS Incluíram-se 54,47% (n=67) do sexo masculino, 45,52% (n=56) do feminino, com média de idade de 37 anos. Destes, 87 eram pessoas vivendo com HIV, 29% (n=25) possuíam lipodistrofia autorreferida; tempo médio de infecção pelo vírus e tratamento antirretroviral (5,80±4,56 e 5,14±3,82 anos), respectivamente. Os pacientes com lipodistrofia autorreferida tiveram maior alteração na distribuição da gordura corporal entre 3-6 anos de diagnóstico do HIV e um perfil colesterolêmico negativo. O tempo de tratamento com antirretroviral influenciou o colesterol total e os triglicerídeos, mesmo para os pacientes sem lipodistrofia autorreferida, com mais de nove anos sob tratamento. CONCLUSÃO Neste estudo, o perfil colesterolêmico negativo se relacionou principalmente ao tempo de tratamento com antirretroviral, mesmo para os pacientes sem lipodistrofia autorreferida e as alterações na distribuição da gordura corporal, mensuradas por antropometria, se associaram especialmente ao tempo de infecção pelo HIV naqueles com lipodistrofia autorreferida.

ABSTRACT

Anormalidades lipídicas e inflamação sistêmica subclínica estão associadas ao processo de aterosclerose, sendo utilizadas como marcadores de risco cardiovascular. Estudos sugerem um possível efeito benéfico dos produtos lácteos na saúde cardiovascular, mas os resultados em marcadores lipídicos e inflamatórios ainda são controversos. O objetivo deste trabalho foi avaliar a associação entre o consumo de produtos lácteos e seus diferentes subgrupos e proteína C-reativa (PCR), LDL-colesterol (LDL-C) e razão triglicerídeo/HDL-colesterol (TG/HDL-C) nos participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) (n = 9.372). O consumo de lácteos foi avaliado por meio de questionário de frequência alimentar validado e apresentado em porções/dia. O consumo total de lácteos foi descrito em quatro categorias (≤ 1 porção/dia a > 4 porções/dia). As associações foram estimadas por meio do odds ratios (OR), utilizando-se o grupo de menor consumo (≤ 1 porção/dia) como referência. Os menores valores de OR para TG/HDL-C no modelo multivariado (0,70; IC95%: 0,55-0,90 em homens; e 0,55; IC95%: 0,43-0,70 em mulheres) foram encontrados no grupo com consumo > 4 porções/dia de lácteos totais. Esses resultados foram apoiados pelas associações inversas encontradas entre diferentes subgrupos de lácteos e a razão TG/HDL-C. Não foi encontrada associação entre consumo de produtos lácteos e seus subgrupos e valores de LDL-C e de PCR. Os resultados sugerem um possível efeito benéfico dos lácteos no perfil lipídico, porém são necessárias evidências de estudos longitudinais e de intervenção que elucidem os mecanismos de efeito dos diferentes tipos de lácteos.


Lipid abnormalities and subclinical systemic inflammation are associated with atherosclerosis and are used as markers of cardiovascular risk. Studies have suggested a possible beneficial effect of dairy products on cardiovascular health, but the results in lipid and inflammatory markers are still controversial. This study aimed to assess the association between consumption of dairy products and their different subgroups and C-reactive protein (CRP), LDL-cholesterol (LDL-C), and triglyceride/HDL-cholesterol ratio (TG/HDL-C) in participants in the Longitudinal Study of Adult Health (ELSA-Brasil) (n = 9,372). Consumption of dairy products was assessed via a validated food frequency questionnaire and expressed as servings/day. Total consumption of dairy products was described in four categories (≤ 1 serving/day to > 4 servings/day). The associations were estimated via odds ratios (OR), using the group with the lowest consumption (≤ 1 serving/day) as the reference. The lowest ORs for TG/HDL-C in the multivariate model (0.70; 95%CI: 0.55-0.90 in men; and 0.55; 95%CI: 0.43-0.70 in women) were found in the group that consumed > 4 servings day of dairy products. These results were supported by the inverse associations between different subgroups of dairy products and the TG/HDL-C ratio. No association was found between consumption of dairy products and their subgroups and LDL-C and CRP. The results suggest a possible beneficial effect of dairy products on lipid profile, but longitudinal and intervention studies are needed to elucidate the effect mechanisms of different types of dairy products.


Las anormalidades lipídicas e inflamación sistémica subclínica están asociadas con el proceso de arteriosclerosis, siendo utilizadas como marcadores de riesgo cardiovascular. Los estudios sugieren un posible efecto benéfico de los productos lácteos en la salud cardiovascular, pero los resultados en marcadores lipídicos e inflamatorios todavía son controvertidos. El objetivo de este estudio fue evaluar la asociación entre el consumo de productos lácteos y sus diferentes subgrupos y proteína C-reativa (PCR), LDL-colesterol (LDL-C) y razón triglicéridos/HDL-colesterol (TG/HDL-C) en los participantes del Estudio Longitudinal de Salud del Adulto (ELSA-Brasil) (n = 9.372). El consumo de lácteos fue evaluado mediante un cuestionario de frecuencia alimentaria validado, y presentado en porciones/día. El consumo total de lácteos se describió en cuatro categorías (≤ 1 porción/día a > 4 porciones/día). Las asociaciones fueron estimadas mediante odds ratios (OR), utilizando el grupo de menor consumo (≤ 1 porción/día) como referencia. Los menores valores de OR para TG/HDL-C en el modelo multivariado (0,70; IC95%: 0,55-0,90 en hombres; y 0,55; IC95%: 0,43-0,70 en mujeres) se encontraron en el grupo con consumo > 4 porciones/día de lácteos totales. Estos resultados se apoyaron en las asociaciones inversas encontradas entre diferentes subgrupos de lácteos y la razón TG/HDL-C. No se encontró asociación entre consumo de productos lácteos y sus subgrupos y valores de LDL-C y de PCR. Los resultados sugieren un posible efecto benéfico de los lácteos en el perfil lipídico, pese a que se necesitan evidencias de estudios longitudinales y de intervención que eluciden los mecanismos de efecto de los diferentes tipos de lácteos.

ABSTRACT

Abstract This study aimed to investigate the effects of chronic restraint stress (RS) and a high-fat diet (HFD) on the osseointegration of titanium implants in a rat model. After the surgical insertion of titanium implants into the metaphysis of the tibial bone, the rats were randomly divided into four equal groups (n = 8 each): control (CNT), restraint stress (RS), high-fat diet (HFD), and restraint stress plus high fat diet (RS-HFD). CNT: Rats received no further treatment during the 92-day experimental period. RS: Stress was applied to the rats beginning from two days after the implant surgery for one hour per day for the first 30 days, two hours per day for the next 30 days, and three hours per day for the last 30 days. HFD: Rats were fed a HFD for the following 90 days starting two days after surgery. RS-HFD: Rats were fed a HFD and RS was applied to rats for the following 90 days, starting two days after surgery. At the end of the experimental period, the rats were euthanized, and the implants and surrounding bone tissues were removed for histological analysis. Statistical analysis was performed by one way ANOVA and Bonferrroni tests. There were no significant differences in the bone-implant connection levels between the groups (p > 0.05), but in the HFD and RS-HFD groups, the bone filling ratios were found to be lower compared with the controls (p < 0.05) The data analyzed in this study suggest that an HFD with or without chronic RS adversely affected bone tissue in the rats during the 90-day osseointegration period.

ABSTRACT

The consumption of alcoholic beverages influences carbohydrate and lipid metabolism, although it is not yet clear whether metabolism during physical exercise at different intensities is also affected. This was the objective of the present study. Eight young and healthy volunteers performed a treadmill test to identify the running speed corresponding to a lactate concentration of 4 mM (S4mM). At least 48 h later, they were subjected to two experimental trials (non-alcohol or alcohol) in which they performed two 1-km running sessions at the following intensities: 1) S4mM; 2) 15% above S4mM. In both trials, blood lactate, triglycerides, and glucose concentrations were measured before and after exercise. The acute alcohol intake increased triglycerides, but not lactate concentration under resting conditions. Interestingly, alcohol intake enhanced the exercise-induced increase in lactate concentration at the two intensities: S4mM (non-alcohol: 4.2±0.3 mM vs alcohol: 4.8±0.9 mM; P=0.003) and 15% above S4mM trial (P=0.004). When volunteers ingested alcohol, triglycerides concentration remained increased after treadmill running (e.g., at S4mM - at rest; non-alcohol: 0.2±0.5 mM vs alcohol: 1.3±1.3 mM; P=0.048). In contrast, glucose concentration was not modified by either alcohol intake, exercise, or their combination. We concluded that an acute alcohol intake changed lactate and lipid metabolism without affecting blood glucose concentration. In addition, the increase in lactate concentration caused by alcohol was specifically observed when individuals exercised, whereas augmented triglycerides concentration was already observed before exercise and was sustained thereafter.

ABSTRACT

Abstract Objective: Correlate serum magnesium (Mg) and Calcium (Ca) levels with body composition and metabolic parameters in women with fibromyalgia (FM). Patients and methods: Cross-sectional study compared with a control group paired by age and body mass index (BMI) of adult women diagnosed with fibromyalgia. All participants went through assessment of their body composition through dual-energy X-ray absorptiometry (DXA) and had blood samples collected for dosing of Mg, Ca, C-reactive Protein (CRP), lipidogram and glycemia. Results: 53 women with FM (average age 48.1 ±8.2 years, average BMI 26.6 ±4.5 kg/m2) and 50 control women (average age 47.1 ±9.9 years, average BMI 25.6 ± 3.6 kg/m2) participated in the study. Serum levels turned out to have inverse correlation with CRP in the FM group (r = −0.29, p = 0.03) and with BMI and glycemia in the control group (r = 0.31; p = 0.02 and r = 0.48; p = 0.0004 respectively). Serum levels of calcium correlated with triglycerides (r = 0.29; p = 0.03) in the FM group and with glycemia in the control group (r = 0.64; p = 0.0001). Conclusions: In patients with FM, magnesemia turned out to have inverse correlation with CRP and calcemia had positive association with triglycerides.(AU)

ABSTRACT

OBJECTIVES: To evaluate the acute effects of a session of water-based aerobic exercise on the blood lipid levels of women with dyslipidemia and to compare these results according to their training status. METHOD: Fourteen premenopausal women with dyslipidemia, aged 40-50 years, participated in two water-based aerobic exercise sessions, the first when they were generally sedentary and the second after they were trained with a water-based aerobic training program for 12 weeks. Both experimental sessions were performed using the same protocol, lasted 45 min, and incorporated an interval method, alternating 3 min at a rating of perceived exertion (RPE) of 13 and 2 min at an RPE of 9. Total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and lipoprotein lipase enzyme (LPL) were obtained through venous blood collection before and immediately after each session. A generalized estimating equation method and Bonferroni tests were conducted (with time and training status as factors) for statistical analyses. RESULTS: At enrollment, the mean age of the participants was 46.57 years (95% confidence interval [CI] 44.81−48.34). The statistical analyses showed a significant time effect for all variables (TC: p=0.008; TG: p=0.012; HDL: p<0.001; LPL: p<0.001) except for LDL (p=0.307). However, the training status effect was not significant for any variable (TC: p=0.527; TG: p=0.899; HDL: p=0.938; LDL: p=0.522; LPL: p=0.737). These results indicate that the TC and TG levels reduced and the HDL and LPL concentrations increased from pre- to post-session in similar magnitudes in both sedentary and trained women. CONCLUSIONS: A single water-based aerobic exercise session is sufficient and effective to beneficially modify the lipid profile of women with dyslipidemia, regardless of their training status.

ABSTRACT

ABSTRACT Objective: To determine the relationships that smoking history has with inflammatory markers, metabolic markers, body composition, muscle strength, and cardiopulmonary capacity in current smokers. Methods: This was a cross-sectional study involving 65 smokers (age range: 18-60 years). On three non-consecutive days, each participant was evaluated in terms of smoking history, pre-existing comorbidities, lung function (by spirometry), peripheral muscle strength (by dynamometry), body composition (by bioelectrical impedance analysis), levels of metabolic/inflammatory markers, and maximum cardiopulmonary capacity (by treadmill exercise test). We evaluated the relationships that smoking history has with inflammatory markers, metabolic markers, body composition, muscle strength, and cardiopulmonary capacity, using logarithmic transformation of the data and calculating Pearson's correlation coefficient and for partial correlations adjusted for age, gender, body mass index (BMI), and comorbidities. To identify the influence of smoking history on pre-existing comorbidities, we used a logistic regression model adjusted for age, BMI, and duration of smoking. Results: Smoking history correlated significantly, albeit weakly, with triglyceride level (r = 0.317; p = 0.005), monocyte count (r = 0.308; p = 0.013), and waist circumference (r = 0.299; p = 0.017). However, those correlations did not retain their significance in the adjusted analysis. In the logistic regression model, smoking more than 20 cigarettes/day correlated significantly with the presence of metabolic diseases (OR = 0.31; 95% CI: 1.009-1.701; p = 0.043). Conclusions: In this sample of smokers, smoking history correlated positively with the triglyceride level, the monocyte count, and waist circumference. The prevalence of metabolic disease was highest in those who smoked more than 20 cigarettes/day.


RESUMO Objetivo: Verificar a relação da carga tabágica com marcadores inflamatórios, marcadores metabólicos, composição corporal, força muscular e capacidade cardiorrespiratória em tabagistas. Métodos: Estudo transversal com 65 tabagistas de ambos os sexos (idade: 18-60 anos). Todos os participantes foram avaliados em três dias não consecutivos quanto ao histórico de tabagismo, comorbidades pré-existentes, função pulmonar (espirometria), força muscular periférica (dinamometria), composição corporal (bioimpedância), dosagem de marcadores metabólicos e inflamatórios e teste cardiopulmonar em esteira para avaliar a capacidade cardiorrespiratória máxima. Avaliou-se a relação da carga tabágica com marcadores inflamatórios, marcadores metabólicos, composição corporal, força muscular e capacidade cardiorrespiratória com transformação logarítmica através da correlação de Pearson e correlações parciais ajustadas para idade, sexo, índice de massa corpórea (IMC) e comorbidades. A regressão logística com modelo ajustado para idade, IMC e tempo de tabagismo foi utilizada para identificar a influência do histórico de tabagismo sobre as comorbidades pré-existentes. Resultados: Observaram-se correlações positivas fracas somente para dados não ajustados da carga tabágica com nível de triacilglicerol (r = 0,317; p = 0,005), contagem de monócitos (r = 0,308; p = 0,013) e circunferência abdominal (r = 0,299; p = 0,017). No modelo de regressão logística, fumar mais de 20 cigarros/dia correlacionou-se significativamente com a presença de doenças metabólicas (OR = 0,31; IC95%: 1,009-1,701; p = 0,043). Conclusões: Nesta amostra de tabagistas, a carga tabágica se correlacionou positivamente com nível de triacilglicerol, contagem de monócitos e circunferência abdominal. A prevalência de doenças metabólicas foi maior em tabagistas que fumam mais de 20 cigarros/dia.

ABSTRACT

Abstract Background: Different strategies have been proposed for the cardiovascular risk management of patients with psoriasis. Objective: To estimate the cardiovascular risk and evaluate two cardiovascular prevention strategies in patients with psoriasis, analyzing which proportion of patients would be candidates to receive statin therapy. Methods: A retrospective cohort was selected from a secondary database. All patients >18 years with psoriasis without cardiovascular disease or lipid-lowering treatment were included. The atherosclerotic cardiovascular disease calculator (2018 American College of Cardiology/American Heart Association guidelines) and the Systematic Coronary Risk Evaluation risk calculator (2016 European Society of Cardiology/European Society of Atherosclerosis guidelines) were calculated. The SCORE risk value was adjusted by a multiplication factor of 1.5. The recommendations for the indication of statins suggested by both guidelines were analyzed. Results: A total of 892 patients (mean age 59.9 ± 16.5 years, 54.5% women) were included. The median atherosclerotic cardiovascular disease calculator and Systematic Coronary Risk Evaluation values were 13.4% (IQR 6.1-27.0%) and 1.9% (IQR 0.4-5.2), respectively. According to the atherosclerotic cardiovascular disease calculator, 20.1%, 11.0%, 32.9%, and 36.4% of the population was classified at low, borderline, moderate, or high risk. Applying the Systematic Coronary Risk Evaluation, 26.5%, 42.9%, 20.8%, and 9.8% of patients were stratified as having low, moderate, high, or very high risk, respectively. The proportion of subjects with statin indication was similar using both strategies: 60.1% and 60.9% for the 2018 American College of Cardiology/American Heart Association and 2016 European Society of Cardiology/European Society of Atherosclerosis guidelines, respectively. Study limitations: This was a secondary database study. Data on the severity of psoriasis and pharmacological treatments were not included in the analysis. Conclusion: This population with psoriasis was mostly classified at moderate-high risk and the statin therapy indication was similar when applying the two strategies evaluated.

ABSTRACT

Abstract The use of new technologies can improve screening in communities with difficult access to health. This article aims to evaluate the sensitivity, specificity, and agreement of a point of care test in comparison to laboratory methods for the determination of glucose (GLI), triglyceride (TG), and total cholesterol (TC) concentrations. This prospective study used data from the remaining adult population of quilombolas in Brazil. Laboratory tests using conventional methods for the analysis of venipuncture samples were used as a standard method to measure the concentrations of GLI (mg/dL), TG (mg/dL), and TC (mg/dL) and compared to the metered dose from the collection of fingertip capillary blood (point of care). Contingency tables (2x2) were used to estimate the sensitivity and specificity of the methods. Lin and Bland & Altman coefficients were used to statistically assess agreement, the level of significance was 5%. There was substantial agreement between the methods for measuring TG and poor agreement for of TC and GLI. Analysis of the Bland & Altman coefficients revealed that the fingertip method did not produce good measures. The point of care method did not offer a good ability to measure compared to that of the reference laboratory method.


Resumo O uso de novas tecnologias pode melhorar o screening em comunidades de difícil acesso à saúde. O objetivo deste artigo é avaliar a sensibilidade, especificidade e concordância do teste de point of care em comparação com método laboratorial para dosagem de Glicose (GLI), Triglicerídeo (TG) e Colesterol total (CT). Estudo prospectivo com dados de população de adultos remanescentes de quilombolas no Brasil. Exames laboratoriais convencionais para análise foram obtidos por venopunção, utilizados como método padrão para mensuração das concentrações de GLI (mg/dL), TG (mg/dL) e CT (mg/dL) e comparados a mensuração por meio de técnica de ponta de dedo (point of care). Tabelas de contingência (2x2) foram utilizadas para estimar sensibilidade e especificidade dos métodos e o coeficiente de Lin e análises de Bland & Altman foram métodos de concordância com nível de significância de 5%. Houve concordância substancial entre os métodos para mensuração de TG e fraca concordância para mensuração de CT e GLI. Os coeficientes de Bland & Altman indicam que o método de ponta de dedo não apresentou boa mensuração. O método point of care não apresentou boa capacidade de mensuração de Glicose, Triglicerídeo e Colesterol total tendo como referência o método laboratorial.

ABSTRACT

Abstract Background: In view of the increased global prevalence of cardiovascular and hepatic diseases, the diet lipid content and its relationship with the accumulation of fat in hepatocytes have been investigated as key factors in preventing these diseases. Objective: To evaluate the metabolic effects of a high-lard diet supplemented or not with cholesterol on a modified dyslipidemia model. Methods: We divided 24 adult male Wistar rats into three groups: standard diet (STD - 4% lipids), high-lard diet (HLD - 21% lard), and high-lard and high-cholesterol diet (HL/HCD - 20% lard, 1% cholesterol, 0.1% cholic acid). After six weeks of treatment, blood and liver were collected for biochemical (serum lipid profile and liver enzymes) and morphological analyses. Statistical analysis included one-way analysis of variance (ANOVA), followed by Tukey test for mean comparisons, and a 5% probability was considered statistically significant. Results: Animals fed HL/HCD showed increased total cholesterol, triacylglycerol, LDL-c, non-HDL-c, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) serum levels compared to those fed STD. In addition, the HL/HCD animals presented higher relative liver weight, with moderate macrovesicular hepatic steatosis and inflammatory infiltrate. Conclusion: A high-fat diet with lard (20%) and cholesterol (1%) triggered dyslipidemia with severe liver damage in rats in a shorter experimental time than the previously reported models. The high-lard diet without supplementation of cholesterol led to body weight gain, but not to dyslipidemia.


Resumo Fundamento: Tendo em vista o aumento da prevalência global de doenças cardiovasculares e hepáticas, o conteúdo lipídico da dieta e sua relação com o acúmulo de gordura nos hepatócitos têm sido investigados como fatores-chave na prevenção dessas doenças. Objetivo: Avaliar os efeitos metabólicos de uma dieta rica em banha suplementada com colesterol ou não, em um modelo modificado de dislipidemia. Métodos: Foram divididos 24 ratos Wistar machos adultos em três grupos: dieta padrão (DP - 4% de lipídios), dieta rica em banha (DRB - 21% de banha) e dieta rica em banha e colesterol (DRB/RC - 20% de banha, 1% de colesterol e 0,1% de ácido cólico). Após seis semanas de tratamento, o sangue e o fígado foram coletados para análises bioquímicas (perfil lipídico sérico e enzimas hepáticas) e morfológicas. A análise estatística incluiu análise de variância unidirecional (ANOVA), seguida do teste de Tukey para comparações de médias. Uma probabilidade de 5% foi considerada estatisticamente significativa. Resultados: Animais alimentados com DRB/RC apresentaram um aumento nos níveis séricos de colesterol total, triacilglicerol, LDL-c, não-HDL-c, alanina aminotransferase (ALT) e aspartato aminotransferase (AST) em comparação com aqueles alimentados com DP. Além disso, os animais tratados com DRB/RC apresentaram um peso relativo do fígado maior, com esteatose hepática macrovesicular moderada e infiltrado inflamatório. Conclusão: Uma dieta rica em gordura com banha (20%) e colesterol (1%) desencadeou dislipidemia com danos graves ao fígado em ratos em um tempo experimental menor do que os modelos previamente relatados. A dieta rica em banha sem suplementação de colesterol levou ao ganho de peso corporal, mas não à dislipidemia.

ABSTRACT

SUMMARY OBJECTIVES: To analyze the association between physical activity during life and cardiovascular risk factors among adults. DESIGN: The sample was composed of 101 adults (59 men) between 30 and 50 years old, who were recruited from different gyms and from a University in Brasil. Participants were divided according to their engagement in sports in early life (self-reported) and current physical activity (pedometer) (sports participation during childhood/adolescence and currently active [n=26], sports participation during childhood/adolescence and currently inactive [n=26], and control [n=49]). Cardiovascular risk factors were measured, such as body fat (through DXA), HDL-C, triglycerides, HOMA index, systolic blood pressure, diastolic blood pressure, and C-reactive protein. We adopted the covariates of chronological age, sex, alcohol consumption, tobacco, and body mass index. General estimating equations were used, with p<0.05. RESULTS: After the adjustments of the final model, individuals engaged in sports during childhood and adolescence and inactive during adulthood presented lower body fat, when compared to participants persistently inactive (p<0.001). Participants persistently active presented lower body fat (p<0.001) and lower c-reactive protein (p=0.010) when compared to the control group. CONCLUSION: Early sports participation was associated with reduced body fat, and being physically active throughout life was associated with reduced body fat and C-reactive protein.


RESUMO OBJETIVO: Analisar a associação entre atividade física durante a vida e fatores de risco cardiovasculares entre adultos. DESIGN: A amostra foi composta por 101 adultos (59 homens) entre 30 e 50 anos, os quais foram recrutados em diferentes academias de ginástica e uma universidade brasileira. Os participantes foram divididos de acordo com o engajamento prévio (autorrelatado) e atual de atividade física (mensurada por pedômetro) (participação esportiva durante a infância/adolescência e prática atual [n=26], participação esportiva durante a infância/adolescência e ausência de prática atual [n=26] e controle [n=49]). Como fatores de risco cardiovasculares foram mensurados gordura corporal (por meio de DXA), HDL, triglicérides, índice Homa, pressão arterial sistólica e diastólica, além da proteína c-reativa. Foram adotadas como covariáveis: idade cronológica, sexo, consumo de álcool e índice de massa corporal. Equações gerais de estimativa foram utilizadas adotando p<0,05. RESULTADOS: Após os ajustes no modelo final, indivíduos engajados em esporte durante a infância e adolescência e inativos durante a idade adulta apresentaram menor gordura corporal quando comparados com participantes persistentemente inativos (p<0,001). Participantes persistentemente ativos apresentaram menor gordura corporal (p<0,001) e proteína c-reativa (p=0,010) quando comparados ao grupo controle. CONCLUSÃO: Prática esportiva prévia (durante infância e adolescência) foi associada com redução da gordura corporal e ser fisicamente ativo ao longo da vida foi associado à redução da gordura corporal e proteína c-reativa.
