The bioprotective role of irradiated hibiscus against harmful effects of using repeatedly frying edible oil / O papel bioprotetor do hibisco irradiado contra os efeitos nocivos do uso de óleo comestível para fritar

Abstract Repeatedly frying process of dietary edible oil has a potential role in the generation of free radicals. Therefore, questions have always been raised as to whether, there is an efficient and economical method to reduce the harmful effects of repeated use of frying edible oil. Since hibiscus has been stated to have a wide variety of therapeutic effects, it was important to investigate its properties against harmful effects of free radicals. The current study aspires to find out whether irradiated powder of hibiscus has a protective role against adverse effects of repeated use of frying edible oil. Thirty-five adult male albino rats were equally assigned into five groups. First group"G1" was fed with normal diet as control group, meanwhile, group"G2" the diet mixed with fresh oil, "G3" diet mixed with repeatedly frying oil only, "G4" diet mixed with frying oil treated with hibiscus and "G5" diet mixed with frying oil treated with irradiated hibiscus. Feeding duration was six weeks. Fatty acid analyses of oil as well as peroxide values were determined. Blood and liver samples were collected for biochemical analyses as well as histological study. Repeatedly heated cooked oil has significant increases in peroxide value, acid value, free fatty acid and both conjugated diene and triene compared with repeatedly frying oil treated with hibiscus. Also there are significant increases in cholesterol and triglyceride and impaired in liver functions in "G3"compared with others. In addition, relative to the hibiscus groups, there is a substantial reduction in oxygen consumption in "G3". Both hibiscus as well as irradiated hibiscus attract attention in order to play a vital and economical role against harmful effects of frequent use of frying edible oil on some biological functions but, irradiated hibiscus was more effective.

Resumo O processo de fritura repetida de óleo comestível da dieta tem papel potencial na geração de radicais livres que podem ter efeitos prejudiciais em algumas funções biológicas. Portanto, sempre se questionou se existe uma maneira eficiente e econômica de prevenir ou pelo menos reduzir os efeitos nocivos do uso repetido de óleo comestível para fritar. Como o hibisco tem ampla variedade de efeitos terapêuticos, foi importante investigar suas propriedades como agente antioxidante contra os efeitos nocivos dos radicais livres. O presente estudo pretende descobrir se o pó irradiado de hibisco tem papel protetor contra os efeitos adversos do uso repetido de óleo comestível para fritar. Trinta e cinco ratos albinos machos adultos foram divididos igualmente em cinco grupos. O primeiro grupo "G1" foi alimentado com dieta normal como grupo controle, enquanto o grupo "G2" dieta misturada com óleo fresco, dieta "G3" misturada com óleo de fritura repetida, dieta "G4" misturada com óleo de fritura tratada com hibisco e dieta "G5" misturada com óleo de fritura tratada com hibisco irradiado. A duração da alimentação foi de seis semanas. Foram determinadas as análises de ácidos graxos de óleo, bem como os valores de peróxidos. Amostras de sangue e fígado foram coletadas para análises bioquímicas e estudo histológico. O óleo cozido repetidamente aquecido tem aumentos significativos no valor de peróxido, valor de ácido, ácido graxo livre e dieno e trieno conjugados em comparação com óleo de fritura repetidamente tratado com hibisco. Também há aumentos significativos no colesterol e triglicérides e comprometimento das funções hepáticas no "G3" em comparação com outros. Além disso, em relação aos grupos de hibiscos, há uma redução substancial no consumo de oxigênio no "G3". Tanto o hibisco como o hibisco irradiado chamam atenção por desempenhar papel vital e econômico contra os efeitos nocivos do uso frequente de óleo comestível para fritar em algumas funções biológicas, mas o hibisco irradiado foi mais eficaz.

Lipids profile in children and adolescents with β-thalassemia major

ABSTRACT Introduction: Patients with β-thalassemia major (β-TM) are at risk of developing abnormal lipid profiles. Lipid abnormalities, in turn, have a potential role in the pathogenesis of some clinical aspects of thalassemia Objectives: To evaluate lipid levels and atherogenic indices in β-TM patients compared to healthy children and for any association between lipid levels, lipid peroxidation and inflammatory biomarkers Methods: This case-control study was carried out on 79 patients with β-TM, aged 6 to 16 years, registered at the Basrah Center for Hereditary Blood Diseases and 85 age- and sex-matched apparently healthy children and adolescents. Complete blood count, serum lipids and ferritin, liver function tests, C-reactive protein (CRP), high-sensitivity CRP (hs-CRP) and serum malondialdehyde (MDA) were evaluated Results: Patients with β-TM had significantly lower hemoglobin (Hb), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL) and non-high-density lipoprotein (non-HDL) and significantly higher very low-density lipoprotein (VLDL), triglycerides (TGs), LDL/HDL ratio, MDA, hs-CRP, total serum bilirubin (TSB), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) than the control group (p < 0.05). A bivariate analysis revealed that TC has a significant positive association with Hb. The TG has a significant negative association with Hb and a positive association with serum ferritin. Furthermore, MDA, TG, TSB, ALT and AST were significantly positively correlated with serum ferritin (p < 0.05) Conclusions: Atherogenic dyslipidemia, defined as a high low-density lipoprotein cholesterol (LDL-C/high-density lipoprotein cholesterol (HDL-C) ratio and high TG level, is common among pediatric β-TM patients, it is associated with iron overload and places patients at an increased cardiovascular risk.

Dyslipidemia Among Overweight and Obese Children in Jharkhand: A Hospital-Based Study

Objective: To study the prevalence of common dyslipidemia among overweight and obese children between 2-18 years in a tribal region. Methods: This cross-sectional study was carried out in 151 overweight and obese children aged 2-18 years, who visited the pediatric outpatient department of a tertiary care hospital in Jharkhand between 1 August and 30 November, 2022. Dyslipidemia was defined as anyone of the following: a total cholesterol level of 240 mg/dL, a triglyceride level of 150 mg/dL, a low-density lipoprotein cholesterol level (LDL-C) of 140 mg/dL, a high-density lipoprotein cholesterol level (HDL-C) of 40 mg/dL, or the use of a lipid-lowering drug [8]. Overweight and obesity were defined as per World Health Organization criteria. Result: The prevalence of dyslipidemia was 63.6%. The most common type of dyslipidemia was low HDL-C + high TG levels found in 32.5% (n=49) children. The most prevalent pattern of dyslipidemia in overweight children was low HDL-C (19, 32.3%); and in obese children low HDL-C and high TG levels (39, 42.3%). Conclusion: The prevalence rate of dyslipidemia was high among overweight and obese children in this region. There was a positive association between dyslipidemia and body mass index.

Método indirecto para la verificación del intervalo de referencia del perfil lipídico / Indirect method for the verification of the lipid profile reference range

Introducción: La dislipidemia es uno de los problemas más frecuentes en los niños y adolescentes y su estudio es importante debido a su fuerte correlación con la enfermedad cardiovascular aterosclerótica en adultos. Muchos países desarrollaron valores de referencia nacionales investigando los lípidos séricos utilizando datos basados en la población nacional propia. Nuestro objetivo fue verificar el intervalo de referencia del perfil lipídico calculando las curvas de percentiles a través del método indirecto en nuestra población pediátrica. Materiales y métodos: Se analizaron los resultados de nuestra base de datos utilizando el método indirecto. Luego de aplicar filtros y criterios de exclusión se calcularon los percentiles 25, 50, 75, 95 y 99 para colesterol total (CT), colesterol HDL (C-HDL), colesterol no HDL (C-no-HDL), triglicéridos (TG) y colesterol LDL (C-LDL) y para el C-HDL además se calculó el percentil 10. El valor de referencia para el cambio (RCV) se utilizó para determinar si existía diferencia clínicamente significativa entre los valores de percentiles obtenidos y los utilizados en el consenso de la SAP. Resultados: No se evidenció diferencia clínicamente significativa contra los valores propuesto por la SAP, excepto para los TG para las edades 1,5,7 años en el percentil 95 y para la edad de 8 años en el percentil 75 y 95; para el C-HDL en el percentil 10 para las edades 1,16 y 17 años. Discusión: Se obtuvieron los percentiles de los lípidos y se compararon con los valores de referencia utilizados por el consenso en el que están basados las guías (AU)

Introduction: Dyslipidemia is one of the most common problems in children and adolescents and its study is important because of its strong correlation with atherosclerotic cardiovascular disease in adulthood. Many countries have developed national reference values investigating serum lipids using data based on their own national population. Our aim was to verify the lipid profile reference range by calculating percentile curves through the indirect method in our pediatric population. Materials and methods: The results of our database were analyzed using the indirect method. After applying filters and exclusion criteria, the 25th, 50th, 75th, 95th, and 99th percentiles were calculated for total cholesterol (TC), HDL cholesterol (HDL-C), non-HDL cholesterol (non-HDL-C), triglycerides (TG), and LDL cholesterol (LDL-C); for HDL-C, the 10th percentile was also calculated. The reference change values (RCV) were used to determine whether there was a clinically significant difference between the percentile values obtained and those used in the consensus of the Argentine Association of Pediatrics (SAP). Results: There was no clinically significant difference with the values proposed by the SAP, except for TG for ages 1, 5, and 7 years at the 95th percentile and for age 8 years at the 75th and 95th percentile; and for HDL-C at the 10th percentile for ages 1, 16, and 17 years. Discussion: Lipid percentiles were obtained and compared with the reference values used by the consensus on which the guidelines are based (AU)

A study on lipid profile in thyroid dysfunction

Background: Thyroid diseases are among the most common endocrine disorders worldwide. Thyroid hormones play a key role in regulating the synthesis, metabolism, and mobilization of lipids. Levels of circulating lipids may alter in thyroid dysfunction. Aim and Objectives: The aim of the study was to find out the alterations of lipid levels in thyroid dysfunction. Materials and Methods: The study was designed as cross-sectional observational study and analysis of values was done by significant tests difference in means. 20 patients with hypothyroidism, 20 patients with hyperthyroidism, and 20 normal were participated in the study. Levels of total cholesterol, triglycerides, high density lipoprotein cholesterol (HDL-C), very low density lipoprotein cholesterol (VLDL-C), LDL-C, and LDL/HDL ratio were estimated and compared. Results: In patients with hypothyroidism, there was an increase in total cholesterol, LDL-C, and triglyceride levels and decrease in HDL-C levels. In hyperthyroidism, total cholesterol, triglycerides, LDL-C, VLDL-C, and LDL/HDL ratio were found to be significantly decreased. Conclusion: Altered thyroid function can lead to significant changes in the lipid profile. Hypothyroidism is an important risk factor for heart diseases. Hence, routine screening of thyroid hormones may be of considerable help for early intervention and treatment of thyroid dysfunction-related cardiac disease.

Adiposidad y perfil lipídico en mujeres posmenopáusicas venezolanas / Adiposity and lipid profile in venezuelan postmenopausal women / Adiposidade e perfil lipídico em mulheres pós-menopáusicas venezuelanas

Resumen Durante la menopausia se producen cambios metabólicos que favorecen la ganancia de peso y la obesidad abdominal, lo cual facilita el desarrollo de dislipidemias y aumenta el riesgo cardiovascular. El propósito del estudio fue comparar el perfil lipídico y los índices de riesgo cardiometabólico (IRCM) entre mujeres posmenopáusicas del Municipio Naguanagua, Estado Carabobo, Venezuela, clasificadas de acuerdo con su grado de adiposidad. El estudio fue de corte transversal, descriptivo, en el cual participaron 205 mujeres con una mediana de edad de 56 años. Se evaluaron indicadores de adiposidad: índice de masa corporal (IMC), porcentaje de grasa corporal (PGC), circunferencia de cintura (CC), e índice cintura/talla (ICT); así como el perfil lipídico y los IRCM. Se encontraron altos porcentajes de exceso de peso (80%), exceso de grasa corporal (92%), obesidad abdominal (61%) y riesgo metabólico de acuerdo con el ICT (69%). Las mujeres con obesidad mostraron los valores más bajos de cHDL, y aquellas con grasa muy alta, obesidad abdominal y riesgo metabólico de acuerdo con el ICT, los valores más elevados del índice TG/HDL. Se recomiendan otros estudios en este grupo poblacional para comprender mejor la asociación encontrada entre el grado de adiposidad y las alteraciones en el metabolismo de los lípidos con el fin de tomar acciones preventivas en estos trastornos relacionados con el síndrome metabólico.

Abstract During menopause, metabolic changes occur that promote weight gain and abdominal obesity, facilitating the development of dyslipidemias and increasing cardiovascular risk. The purpose of the study was to compare the lipid profile and the cardiometabolic risk indexes (IRCM) among postmenopausal women from the Naguanagua Municipality, Carabobo State, Venezuela, classified according to their degree of adiposity. It was a cross-sectional, descriptive study in which 205 women with a median age of 56 years participated. Adiposity indicators were evaluated: body mass index (BMI), percentage of body fat (PBF), waist circumference (WC), and waist-to-height ratio (WHtR); as well as the lipid profile and the IRCM. High percentages of excess weight (80%), excess body fat (92%), abdominal obesity (61%) and metabolic risk according to the WHtR (69%) were found. Women with obesity showed the lowest values of HDL-C, and those with very high fat, abdominal obesity, and metabolic risk according to the WHtR, the highest values of the TG/HDL index. Other studies are recommended on this population group to better understand the association found between the degree of adiposity and alterations in lipid metabolism to take preventive actions in these disorders related to the metabolic syndrome.

Effect of Hayani Date (Phoenix dactylifera L) Peels on Blood Sugar, Blood Lipids, Liver and Kidney Functions, and Inflammation in Diabetic Rats

This study aimed to investigate the effect of Hayani date peel powder and its methanolic extract on glycemia and lipidemia in streptozotocin-induced diabetic rats as well as their effects on kidney and liver functions in addition to their anti-inflammatory activity. Twenty-four rats were used in this study, six of them served as normal control (group 1) which continued feeding on the basal diet, while the remaining 18 rats were injected with streptozotocin (50mg/kg) to induce diabetes. The diabetic rats were divided into three groups (6 rats each), one of them feeding on the basal diet only which acted as diabetic control (group 2), another group fed on the basal diet and treated orally with the peel extract in a concentration of 250 mg/kg body weight (group 3), while the third group was treated with peel powder merged in the basal diet with a concentration of 5% w/w (group 4). The results showed that the extract and the powder of the peels significantly decreased the blood glucose, glycated hemoglobin (HbAlc), total cholesterol (TC), total triglycerides (TG), low density lipoprotein cholesterol (LDL-c), very low density lipoprotein cholesterol (VLDL-c), alanine transaminase (ALT), aspartate transaminase (AST), creatinine, and uric acid as well as cyclooxygenase-2 (COX-2), prostaglandin 2 (PGE2), tumor necrosis factor alpha (TNF-?), interleukin 1B (IL-1?), and inducible nitric oxide synthase (iNOS) levels. In contrast, significant increases in serum insulin, high density lipoprotein cholesterol (HDL-c), and albumin were noticed in comparison to diabetic control. Generally, the peel extract was more effective than the peel powder. It is recommended by eating the whole fruit of date without peeling.

Lipid profile of chronic kidney disease patients on two different modalities of treatment: Conservative versus hemodialysis

Background: Chronic kidney disease (CKD) is an irreversible deterioration of renal function and cardiovascular disease is the leading cause of mortality in CKD patients. Aims and Objectives: The aim of this study was to assess the pattern of lipid profile among cases of CKD. Materials and Methods: A cross-sectional study was conducted for 1 year covering total 200 cases (males and females) of newly diagnosed or known cases of CKD. Parameters recorded were as follows: Fasting blood sugar, Serum urea (S. Urea), Serum Creatinine (S. Creatinine), and lipid profile. Estimated glomerular filtration rate (eGFR) was calculated by Cockcroft-Gault formula. Results: Mean age was 51.04 years in conservative management patients and 53.20 years in hemodialysis patients. Overall, male-to-female ratio was 1.82:1. S. Creatinine, S. Urea, and eGFR were deranged more in patients on hemodialysis (Group 2). Mean values of low-density lipoprotein (LDL)-cholesterol, very low-density lipoproteins (VLDL), and serum triglycerides (TG) were significantly higher in patients on hemodialysis compared to those on conservative management, while mean high-density lipoprotein cholesterol was significantly lower. Dyslipidemia was more common in female CKD patients (P = 0.02). Conclusion: Dyslipidemia in CKD worsened as patients progressed to severe stages with significant increase in TG, LDL, and VLDL levels in hemodialysis cases in comparison to conservatively managed, confirming presence of atherogenic lipid profile needing early intervention to prevent cardiovascular complications.

A correlation study of arterial stiffness, cardiac autonomic neuropathy and lipid profile in type 2 diabetes mellitus patients

Objectives: Micro and macrovasculopathy are common complications of undertreated or undiagnosed type 2 diabetes mellitus (T2DM) patients. One of the underlying factors of macrovasculopathy is arterial stiffness, which may lead to cardiovascular and cerebrovascular diseases. Understandably, diabetic micro and macrovasculopathy affect vital functions, which may affect the well-being of the individual. However, few studies have attempted to determine arterial stiffness, cardiac autonomic neuropathy (CAN) and lipid profile separately in South Asian population and examined its associations with T2DM. Moreover, there is a need to understand the mechanistic links among cardiovascular risk factors. This forms the basis of the present study. Materials and Methods: T2DM patients of 53–62 years and age- and gender-matched healthy control subjects were recruited in the cross-sectional and observational study (n = 30 each, eight women). Anthropometric measurements, physiological parameters such as resting heart rate, peripheral blood pressure (PBP), central blood pressure (CBP), augmentation index% (AIx%), brachial-ankle pulse wave velocity and lead II ECG for analysis of heart rate variability parameters were recorded after obtaining the consent of the study participants. The lipid profile and fasting blood glucose were also analysed. Results: Peripheral systolic blood pressure was significantly higher (P = 0.05) in T2DM patients. Dyslipidaemia was evident in T2DM patients. Atherogenic index of plasma (AIP) was also significantly higher in T2DM patients. Correlation analysis revealed a positive association between AIx% with PBP and CBP as well as between AIP index and central systolic blood pressure, serum triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein cholesterol (VLDL-C) levels. AIP index was found to be negatively associated with HF (nu). Serum TG, high-density lipoprotein cholesterol (HDL-C) levels and AIP index have emerged as significant independent predictors of T2DM vasculopathy by multiple regression analysis. Conclusion: In the present study, atherogenic dyslipidaemia was observed in T2DM patients in combination with increased serum levels of TG, VLDL-C and decreased serum levels of HDL-C. Moreover, AIP index, a predictor cardiovascular risk, was found to be significantly higher in T2DM patients. Dyslipidaemia was found to be associated with dysregulation of autonomic nervous system in those patients. A positive association between noninvasive, surrogate markers of arterial stiffness with PBP and CBP indicates that enhanced arterial stiffness may elevate systemic arterial pressure. Therefore, early screening of T2DM patients for the estimation of serum lipid profile, arterial stiffness and cardiac autonomic neuropathy may be performed to unravel diabetic vasculopathy.

Positive Stimulatory Potentials of Coconut (Cocos nucifera L.) Juice Extract on in vivo Antioxidants, Renal Function and Lipid Profile of Male Wistar Rats

Coconut juice is a natural drink from coconut fruit. This study was aimed at evaluating its positive potential on biochemical indices. Fresh coconut fruits were de-dshelled and washed. The cotyledon was broken to extract the water which was used in blending the fruits. The extract was filtered and the filtrate was collected in a vial. Twenty healthy male Wistar rats weighing 160 -180 g, were grouped into two groups of ten rats each and were treated as follows for four weeks. Group A: control rats received oral dose of 2 mL/kg body weight of distilled water once daily for 28 days, and group B: received oral dose of 2 mL/kg body weight of coconut juice extract once daily for 28 days, both groups were, however, allowed free access to feed and water ad-libitum. The animals were weighed before and on completion of the experimental protocol. Blood was also collected via cardiac puncture and used for renal function and lipid profile assay, kidneys were excised and weighed, homogenized and the supernatant was used for antioxidant enzyme evaluation. Findings showed that there was no significant change (p>0.05) in the kidney-to-body weight ratio and renal function indices. Significant reduction (p<0.05) was seen in cholesterol, triglycerides, LDL but with an increase (p<0.05) in HDL. Antioxidant enzymes were significantly increased (p<0.05). The study concludes that coconut juice extract has positive stimulatory potentials on antioxidants, renal functions and lipid parameters of wistar rats.

Association of insulin resistance and lipid profile with serum T3, T4, and TSH in patients with hypothyroidism

Background: Hypothyroidism is a common endocrine derangement met with in clinical practice. Deficiency of thyroid hormones can have a significant effect on lipid and carbohydrate metabolism. Aims and Objectives: The aim of the study was to study the association of insulin resistance and lipid profile with serum triiodothyronine (T3), tetraiodothyronine (T4), and thyroid-stimulating hormone (TSH) in hypothyroidism. Materials and Methods: A comparative cross-sectional study was conducted in a tertiary care hospital after obtaining clearance from the Institutional Ethics Committee. Thirty primary hypothyroid subjects were selected as cases based on their TSH values (>4 uIU/mL) and thirty normal subjects as controls after proper exclusion and after getting the informed consent. Their fasting plasma glucose levels, lipid profile, and serum T3, T4, TSH were measured. Homeostasis model Assessment using OXFORD HOMA 2 CALCULATOR was used to determine the insulin resistance (HOMA-IR). Results: The mean values of HOMA-IR, total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides were significantly higher in hypothyroid group than in normal controls. HOMA-IR showed a significant negative correlation with T3 and T4. The correlations of HOMA-IR, total cholesterol, LDL cholesterol, and triglycerides with TSH were positive. Conclusion: The present study shows that hypothyroidism leads to an elevated insulin resistance and dyslipidemia.

Hyperlipidemia in patients with chronic kidney disease on hemodialysis/conservative management

Background: The prevalence of chronic renal failure has increased, as has the need for renal replacement therapy, as both diabetes and hypertension have become more prevalent. Patients’ mortality rates from cardiac causes have increased despite effective monitoring and care. Dyslipidemia significantly contributes to the risk of arteriosclerotic cardiovascular disease, the main cause of death in people with chronic kidney disease (CKD). Aims and Objectives: The objectives of this study were to measurement of hyperlipidemia in patients with CKD on hemodialysis/conservative management. Materials and Methods: The investigation was conducted on 250 patients with CKD at all stages who were receiving hemodialysis and conservative of both sexes aged 20 years or more and sex-matched healthy control subjects. Lipid profiles of each subject were measured in specimens. Results: In our study, dyslipidemia was identified as having high levels of total cholesterol, triglycerides, and low-density lipoprotein and low levels of high-density lipoprotein. Conclusion: The significance of dyslipidemia as a standalone risk factor for coronary artery disease (CAD) in CKD patients was examined in this study. Hence, based on the evidence presented above, we conclude that close monitoring of the ideal cholesterol levels in CKD patients is necessary to reduce the risk of CAD-related death. In CKD patients, monitoring and treating dyslipidemia can reduce mortality.

Glycemic control and dyslipidemia in type 2 diabetic patients in an Indian rural tribal locality: A family medicine practitioner’s perspective

Background: Diabetes and dyslipidemia commonly coexist, frequently associated with various cardio-vascular (CV) risk factors and good glycemic control is key for prevention of long-term CV complications. Although diabetes and dyslipidemia commonly coexist in India, there is a lack of evidence on pattern of dyslipidemia and whether dyslipidemia is adequately managed or not, particularly in rural population in a real-world setting. Aims and Objectives: This study was conducted to assess present glycemic status and lipid profile of the population residing in a rural tribal locality of Jharkhand (India) as part of project for fellowship in diabetes course by Department of Endocrinology, DEDU, CMC, Vellore. Materials and Methods: This non-interventional cross-sectional study was conducted in a tribal locality of Jharkhand (India) after concept note approval for ethical clearance from CMC Vellore. Whole-blood and sera of diabetic patients were analyzed for fasting-blood-sugar, Glycated-hemoglobin (HbA1c), total-cholesterol (CH), triglycerides (TGs), high-density-lipoprotein-cholesterol, low-density-lipoprotein-cholesterol, and very-VLDL-C. Correlation test of HbA1c with lipid-ratios and individual lipid indexes was done. Results: Mean Hb1Ac level was 7.24 ± 1.80 and interestingly, was marginally higher (7.31 ± 1.92 vs. 6.92 ± 1.16) in patients with DM <5 years as compared to those with DM >5 years. Mixed dyslipidemias were common with abnormal TG, LDL, VLDL, High-density lipoprotein (HDL), and Total CH values. Hb1Ac-levels showed significant positive correlation with serum CH, TG, LDL, and VLDL levels while significant negative correlation with HDL levels in the study. Conclusion: Apart from a reliable indicator of long-term glycemic control, HbA1c can also be used as a predictor of dyslipidemia and thus early diagnosis of dyslipidemia can prevent life-threatening CV-complications.

The role of purslane in modulating diverse effects of high fat diet on biochemical, histological, and molecular parameters of rats' liver / O papel da beldroega na modulação de diversos efeitos da dieta rica em gordura nos parâmetros bioquímicos, histológicos e moleculares do fígado de ratos

Abstract Consuming a high-fat diet causes a harmful accumulation of fat in the liver, which may not reverse even after switching to a healthier diet. Different reports dealt with the role of purslane as an extract against high-fat diet; meanwhile, it was necessary to study the potential role of fresh purslane as a hypolipidemic agent. This study is supposed to investigate further the potential mechanism in the hypolipidemic effect of fresh purslane, by measuring cholesterol 7a-hydroxylase (CYP7A1) and low-density lipoprotein receptor (Ldlr). Rats were divided into two main groups: the first one is the normal control group (n=7 rats) and the second group (n=28 rats) received a high fat diet for 28 weeks to induce obesity. Then the high fat diet group was divided into equal four subgroups. As, the positive control group still fed on a high fat diet only. Meanwhile, the other three groups were received high-fat diet supplemented with a different percent of fresh purslane (25, 50 and 75%) respectively. At the end of the experiment, rats were sacrificed and samples were collected for molecular, biochemical, and histological studies. Current study reported that, supplementation of fresh purslane especially at a concentration of 75% play an important role against harmful effects of high-fat diet at both cellular and organ level, by increasing CYP7A1 as well as Ldlr mRNA expression. Also, there were an improvement on the tested liver functions, thyroid hormones, and lipid profile. Fresh purslane plays the potential role as a hypolipidemic agent via modulation of both Ldlr and Cyp7A, which will point to use fresh purslane against harmful effects of obesity.

Resumo O consumo de uma dieta rica em gordura causa um acúmulo prejudicial de gordura no fígado, que pode não reverter mesmo após a mudança para uma dieta mais saudável. Diferentes relatórios trataram do papel da beldroega como um extrato contra uma dieta rica em gordura; entretanto, foi necessário estudar o papel potencial da beldroega fresca como agente hipolipemiante. Este estudo pretende investigar mais profundamente o mecanismo potencial no efeito hipolipidêmico da beldroega fresca, medindo o colesterol 7a-hidroxilase (CYP7A1) e o receptor de lipoproteína de baixa densidade (Ldlr). Os ratos foram divididos em dois grupos principais: o primeiro é o grupo controle normal (n = 7 ratos) e o segundo grupo (n = 28 ratos) recebeu dieta rica em gorduras por 28 semanas para induzir a obesidade. Em seguida, o grupo de dieta rica em gordura foi dividido em quatro subgrupos iguais. Como, o grupo de controle positivo ainda se alimentava apenas com dieta rica em gordura. Enquanto isso, os outros três grupos receberam dieta rica em gordura suplementada com diferentes porcentagens de beldroegas frescas (25%, 50% e 75%), respectivamente. Ao final do experimento, os ratos foram sacrificados e amostras coletadas para estudos moleculares, bioquímica e histológicos. O estudo atual relatou que a suplementação de beldroegas frescas, especialmente a uma concentração de 75%, desempenha papel importante contra os efeitos prejudiciais da dieta rica em gordura em nível celular e orgânico, aumentando a expressão de CYP7A1 e Ldlr mRNA. Além disso, houve melhora nas funções hepáticas testadas, nos hormônios tireoidianos e no perfil lipídico. Beldroegas frescas desempenham papel potencial como agente hipolipemiante por meio da modulação de Ldlr e Cyp7A, o que apontará para o uso de beldroegas frescas contra os efeitos nocivos da obesidade.

Liver-protectant and cardiovascular-protectant effects of Nigella sativa: a meta-analysis / 数字中医药（英文）

@#【Objective】  A significant amount of evidence has lately revealed that individuals with nonalcoholic fatty liver diseases (NAFLD) are at high risk of cardiovascular diseases, which is the primary cause of death in patients. This study is to evaluate liver- and cardiovascular-protectant effects of Nigella sativa (N. sativa). 【Methods】  The meta-analysis was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The literature review was conducted in June 2022 with papers retrieved from the PubMed, ScienceDirect, and Cochrane Library websites from January 2010 to December 2021. The Review Manager version 5.3 was applied for the statistical analysis of parameters like aspartate transaminase (AST) and alanine transaminase (ALT) levels, lipid profil, blood glucose level, weight, and body mass index (BMI). 【Results】  The results showed that N. sativa could significantly decrease the AST (P = 0.009) and ALT (P < 0.05) levels in research subjects. Subjects in the N. sativa group had a significant higher cure rate of fatty liver than those in the placebo group (P = 0.000 1). In addition, lipid profile, blood pressure, and fasting blood glucose of subjects all significantly reduced in the N.sativa group (P < 0.05). However, the comparison of body weight and BMI between the N.sativa group and placebo group did not show significant difference (P > 0.05). 【Conclusion】 N. sativa did have certain liver-protectant and cardiovascular-protectant effects on patients with NAFLD or chronic liver diseases (CLD), despite the insignificant comparison of body weight and BMI between the N. sativa group and the placebo group.

The potential relationship between serum irisin concentration with inflammatory cytokines, oxidative stress biomarkers, glycemic indices and lipid profiles in obese patients with type 2 diabetes mellitus: A pilot study / Journal of the ASEAN Federation of Endocrine Societies

Objectives@#Diabetes mellitus is a serious health-treated problem identified by disorders such as insulin resistance, dyslipidemia, and inflammation. Irisin, a newly discovered myokine/adipokine, is involved in metabolic homeostasis. The present study was carried out to investigate the potential relationship between serum irisin with inflammatory cytokines, oxidative stress biomarkers, glycemic indices, and lipid profiles in obese patients with type 2 diabetes mellitus.@*Methodology@#This analytical cross-sectional study was conducted on 62 participants (n=32 obese participants with diabetes, n=30 participants with normal weight). The participants answered a demographic questionnaire. Serum irisin, glycemic indices, lipid profiles, inflammatory cytokines and oxidative stress biomarkers were measured using standard methods. The difference between groups was assessed by independent-sample t-test or by a non-parametric equivalent. For qualitative variables, the Chi-Square test was used. Pearson rho coefficient was used to determine the potential relationship between irisin and inflammatory cytokines, oxidative stress biomarkers, glycemic indices, and lipid profiles. A p<0.05 was defined as significant.@*Results@#The median (IQR) age of the obese participants with diabetes was 54.0 years (52.2-60.7) and in the normal weight group was 38.0 years (30.0-47.2) (p<0.001). About 78% and 60% of participants in the obese with diabetes and the normal weight groups were females (p>0.05), respectively. Significant differences were observed in serum irisin levels between the two groups, with lower levels (218.74 ng/mL, [144.98-269.26]) noted in the obese with diabetes group compared to the normal weight group (266.68 ng/mL, [200.64-336.57]) with a p=0.024. There was a substantial difference between the two groups regarding IL-6, TNF-α, and hs-CRP (p<0.05). IL-6 had a moderate negative correlation with irisin in obese patients with T2DM (r=-0.478, p=0.006).@*Conclusion@#Irisin concentration was detected to be lower in obese people with diabetes. A negative relationship was detected between irisin and IL-6. Considering emerging evidence about the beneficial functions of irisin in improving metabolic abnormalities, designing future studies with greater sample sizes that will validate these results is needed.

COVID-19 lockdown effects on the anthropometrics, aerobic capacity, muscle function and metabolic control in children and adolescents with overweight and obesity

Abstract Objective: The lockdown due to a novel Coronavirus (COVID-19) pandemic negatively impacted the daily physical activity levels and sedentary behavior of children and adolescents. The purpose of this study was to determine the effects of lockdown on the anthropometric measurements, aerobic capacity, muscle function, lipid profile and glycemic control in overweight and obese children and adolescents. Methods: 104 children and adolescents with overweight and obesity were divided in a non-lock-down group (NL) (n = 48) and a lockdown group (L) (n = 56). Both NL and L groups were evaluated on three consecutive days, day one: anthropometric measurements; day two: aerobic capacity and muscle function and day three: lipid profile and glycemic control. Data are presented as mean ± standard deviation (SD) and median plus interquartile range (IQR) according to their assumption of normality. Results: The L group increased the body weight (81.62 ± 22.04 kg vs 74.04 ± 24.46 kg; p = 0.05), body mass index (32.54 ± 5,49 kg/m² vs 30.48 ± 6.88 kg/m²; p = 0.04), body mass index by z-score (3.10 ± 0.60 SD vs 2.67 ± 0.85 SD; p = 0.0015), triglycerides [141.00 mg/dl IQR (106.00-190.00 mg/dl) vs 103.00 mg/dl IQR (78.50- 141.50 mg/dl); p = 0.001], fasting insulin [31.00 mU/L IQR (25.01 - 47-17 mU/L vs 21.82 mU/L IQR (16.88 - 33.10 mU/L; p = 0.001)] and Conclusions: The lockdown due COVID-19 pandemic had a negative impact on the anthropometric measurements, lipid profile, and glycemic control of overweight and obese children and adolescents.

Cord Blood Lipid Profile of Term and Preterm Newborns in a Tertiary Hospital in South East Nigeria: Relationship with Gestational Age and Birth Weight

Background: Early-onset atherosclerosis is a marker of future cardiovascular diseases. However, indicators of early dyslipidemia for primary prevention are generally lacking in sub-Saharan Africa. This study aimed at describing the cord blood lipid profile among apparently healthy newborns in a tertiary hospital in Southeast Nigeria, and its relationship with gestational age and birth weight.Methods: Cross-sectional study of 167 consecutively recruited apparently well newborns in a tertiary hospital whose cord blood lipid profile parameters (total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL ­C), low-density lipoprotein cholesterol (LDL ­C) and very low-density lipoprotein cholesterol (VLDL ­C)) were assessed using an autoanalyzer (BiOLis 24i). Lipid variables were presented with descriptive statistics whereas their relationship with gestational age and birth weight was highlighted using Spearman's rank correlation analysis. Dunnett's T3 Post Hoc analysis was used for pairwise comparisons.Results: The 167 newborns recruited included 15 (9%) moderate preterm, 46 (27.5%) late preterm and 106 (63.5%) term babies of which 79 (47.3%) were males and 88 (52.7%) were females. The number of recruited SGA, AGA and LGA were respectively 13 (7.8%), 142 (85%), 12 (7.2%). Mode of delivery was majorly vaginal delivery (69.5%) while the rest (30.5%) was by caesarean section. The median values (in mg/dL) of TC, TG, HDL ­C, LDL ­C and VLDL ­C were 60.0, 30.5, 29.0, 25.8 and 6.1 respectively, all within the normal international ranges. Triglycerides and VLDL-C had a moderate positive correlation with gestational age (rs = 0.4;p < 0.001) and were significantly higher in small-for-gestational-age newborns. Total cholesterol, HDL ­C, and LDL-C had a weak negative correlation with gestational age and birth weight (spearman rs˂-0.3). Birth weight, gestational age, and paternal age were the common predictors of lipid profile variability.Conclusion: The finding of a significant relationship between lipid variables with gestational age and birth weight underscores the need to clinically interpret these given the relationship. The relationship with paternal age is another interesting finding which needs to be replicated and the mechanism(s) elucidated.
