ABSTRACT

PURPOSE: To evaluate the progression of early age-related macular degeneration to neovascular age-related macular degeneration (nAMD), and identify the abnormal fundus autofluorescence (FAF) patterns and markers of choroidal neovascularization (CNV) in fellow eyes of patients with unilateral nAMD. METHODS: Sixty-six patients with unilateral nAMD who developed abnormal FAF in the fellow eyes were enrolled in this multicenter, prospective, observational study, and followed-up for 5 years. FAF images on Heidelberg Retina Angiogram Digital Angiography System (HRA) or HRA2 were classified into eight patterns based on the International Fundus Autofluorescence Classification Group system. The patients in which the fellow eyes progressed to advanced nAMD, including those who did not develop nAMD, were assessed based on the following factors: baseline FAF patterns, age, sex, visual acuity, drusen, retinal pigmentation, baseline retinal sensitivity, family history, smoking, supplement intake, hypertension, body mass index, and hematological parameters. RESULTS: Of the 66 patients, 20 dropped out of the study. Of the remaining 46 patients, 14 (30.42%, male: 9, female: 5) progressed to nAMD during the 5-year follow-up. The most common (50% eyes) FAF pattern in the fellow eyes was the patchy pattern. According to the univariate analysis, CNV development was significantly associated with age, supplement intake, and low-density lipoprotein levels (p<0.05). Multivariable analysis revealed that patients who showed non-compliance with the supplement intake were more likely to develop nAMD (p<0.05). No significant association was found between the patchy pattern and CNV development (p = 0.86). CONCLUSION: The fellow eyes (with abnormal FAF) of patients with unilateral nAMD may progress from early to advanced nAMD. However, no FAF pattern was found that predicted progression in nAMD.

ABSTRACT

A diet comprising of nutrients that would control hypertension as well as hyperlipidemia would be very beneficial over all. This study aimed to assess the effect of lyophilized beet root powder at different doses on lipid profile and hyperlipidemia model. Albino rabbits weighing 1500-2000gms were taken for both studies. Beetroot powder was administered to animals at 500mg/kg and 1000mg/kg doses and after two month dosing the blood samples were withdrawn and lipid profile was assessed. Next a model of hyperlipidemia was created comprising of albino rabbits that were divided into five groups each containing n=6. Group I was considered as control, Group II was marked as Negative control, Group III was taken as standard, whereas Group IV and V were considered as treated and given different doses of beetroot. Blood samples were drawn at baseline, 45th day and at day 60th of study. Highly significant decrease in lipid profile (Cholesterol, LDL and TGS) and significant increase in HDL was observed by both doses after one month. HDL was increased more at 1000mg/kg dose. The presence of flavonoids and saponins in beetroot is responsible for hypolipidemic effect. From our research we came to the conclusion that beetroot powder reduced the lipid profile and could be beneficial in treatment of cardiovascular disease due to atherosclerosis and obesity.

ABSTRACT

BACKGROUND: There is little knowledge on the effects of alpha-linolenic acid (ALA) and n-3 long-chain polyunsaturated fatty acids (n-3 LCPUFA) on the LDL lipidome and aggregation of LDL particles. OBJECTIVE: We examined if consumption of Camelina sativa oil (CSO) as a source of ALA, fatty fish (FF) as a source of n-3 LCPUFA and lean fish (LF) as a source of fish protein affect the lipidome of LDL as compared to a control diet. METHODS: Participants with impaired glucose tolerance (39 women and 40 men) were randomized to 4 study groups (CSO providing 10 g/d ALA, FF and LF [both 4 fish meals/wk] and control limiting their fish and ALA intake) in a 12-week, parallel trial. Diets were instructed and dietary fats were provided to the participants. The lipidome of LDL particles isolated from samples collected at baseline and after intervention was analyzed with electrospray ionization-tandem mass spectrometry. RESULTS: In the CSO group, the relative concentrations of saturated and monounsaturated cholesteryl ester species in LDL decreased and the species with ALA increased. In the FF group, LDL phosphatidylcholine (PC) species containing n-3 LCPUFA increased. There was a significant positive correlation between the change in total sphingomyelin and change in LDL aggregation, while total PC and triunsaturated PC species were inversely associated with LDL aggregation when all the study participants were included in the analysis. CONCLUSION: Dietary intake of CSO and FF modifies the LDL lipidome to contain more polyunsaturated and less saturated lipid species. The LDL surface lipids are associated with LDL aggregation.

ABSTRACT

The present investigation was an attempt to evaluate the hypoglycemic, lipid-lowering, antioxidant and hepatoprotective effects of cumin (Cuminum cyminum family: Apiaceae) supplementation in high fat (HF) diet fed rats. Male Wistar rats were divided into four groups, such as control, control+ cumin, HF and HF+ cumin. Oral glucose tolerance test, plasma lipids, oxidative stress parameters, antioxidant enzymes activities, and liver dysfunction marker enzyme activities were evaluated. Additionally, histological staining of liver tissue was performed to evaluate the inflammatory cells infiltration, iron deposition and fibrosis. The current investigation demonstrated that 1% (w/w) supplementation of cumin powder significantly reduced HF diet-induced glucose intolerance, epididymal and mesenteric fat wet weights and lipid parameters like triglycerides, total cholesterol and low-density lipoproteins. Oxidative stress-related biomarkers including thiobarbituric acid reactive substances (TBARS), nitric oxide (NO) and advanced oxidation protein product (APOP) were also reduced by cumin supplementation. Moreover, HF-diet increased the activity of hepatic biomarker enzymes such as alanine transaminase (ALT) and alkaline phosphatase (ALP) activities which were significantly reduced by cumin powder supplementation. On the other hand, cumin powder supplementation was able to restore the reduced glutathione level with parallel augmentation of the antioxidant enzymes activities such as superoxide dismutase (SOD) and catalase in liver of HF diet-fed rats. Additionally, histological assessments confirmed that cumin powder supplementation also normalized the fat droplet deposition and inflammatory cells infiltration in the liver of HF diet-fed rats. This study suggests that cumin powder supplementation ameliorates dyslipidemia, oxidative stress and hepatic damage in HF diet-fed rats.

ABSTRACT

AIMS: Current study aimed to evaluate the effect of vitamin D supplementation on flow-mediated dilatation (FMD), oxidized LDL (oxLDL) and intracellular adhesion molecule 1 (ICAM1) in type 2 diabetic patients with hypertension. METHODS: In a double-blinded, placebo-controlled trial, 44 patients were randomly divided into vitamin D group (2000 IU/d, n = 23) and placebo group (control, n = 21) for 12 weeks. Vascular function with FMD, Serum 25-OH vitamin D, oxLDL and ICAM1 were assessed at the baseline and after the intervention. This clinical trial was registered at Iranian Registry of Clinical Trials (IRCT20191223045861N1). RESULTS: In intervention group serum level of vitamin D increased from 32.42 ± 10.56 to 40.45 ± 12.94 (p < 0.001). In the vitamin D group, oxLDL and ICAM1 significantly decreased and FMD increased significantly in both groups (p < 0.001). The level of oxLDL (p = 0.017) and ICAM1 (p < 0.001) were significantly lower in the vitamin D group than the placebo group and FMD (p < 0.001) was significantly higher in the vitamin D group. CONCLUSIONS: Vitamin D supplementation of 2000 IU/d for 12 weeks can improve endothelial function and decrease ICAM1 and oxLDL in type 2 diabetic patients with hypertension.

ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: Si-Miao-Yong-An decoction (SMYAD) is a renowned traditional Chinese medicinal formula. SMYAD was originally recorded in the "Shi Shi Mi Lu", which was edited by medical scientist Chen Shi'duo during the Qing Dynasty. SMYAD has been traditionally used to treat thromboangiitis obliterans. At present, it is mainly used in clinical applications and research of cardiovascular diseases. AIM OF THE STUDY: To explore the effects of SMYAD on the pathological changes of atherosclerosis (AS) and the differentiation of monocytes, macrophages, and regulatory T (Treg) cells in apolipoprotein E knockout (ApoE-/-) mice. MATERIALS AND METHODS: Eight C57BL/6J mice, which were fed with normal diet for 16 weeks, were used as control group. Forty ApoE-/- mice were randomly divided into model group, atorvastatin group, SMYAD low-dose (SMYAD-LD) group, SMYAD medium-dose (SMYAD-MD) group, and SMYAD high-dose (SMYAD-HD) group. ApoE-/- mice were fed with western diet (WD) for 8 weeks, and the drugs were continuously administered for 8 weeks. The levels of serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were measured by the esterase method. Morphological changes of the aortic sinus in mice were observed by hematoxylin-eosin (HE) staining, the lipid infiltration of the aorta and aortic sinus were observed by oil red O staining, and the spleen index was calculated. The proportion of Ly6Chigh and Ly6Clow monocyte subsets, macrophages, and their M1 phenotype, as well as Treg cells in spleen were measured by flow cytometry. The expressions of cluster of differentiation 36 (CD36), scavenger receptor A1 (SRA1), lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1), F4/80, and fork head frame protein 3 (FOXP3) in aortic sinus were assessed by immunohistochemical staining. The serum levels of oxidized low density lipoprotein (ox-LDL), interleukin-1ß (IL-1ß), IL-18, transforming growth factor-ß (TGF-ß), and IL-10 were measured by enzyme-linked immunosorbent assays (ELISA). RESULTS: Compared with the model group, the level of serum TC and LDL-C decreased in the SMYAD group, the pathological changes of aortic sinus decreased, and lipid infiltration of aorta and aortic sinus also decreased. These decreases were accompanied by a significant downregulation of CD36, SRA1, and LOX-1. Furthermore, the proportions of Ly6Chigh pro-inflammatory monocyte subsets, macrophages, and their M1 phenotypes in spleen decreased significantly, while the proportion of Treg cells increased. In addition, while the expression of F4/80 decreased, the expression of FOXP3 increased in the aorta sinus. The levels of serum pro-inflammatory factors IL-1ß and IL-18 decreased. CONCLUSIONS: SMYAD can improve the pathological changes associated with AS and can inhibit lipid deposition in ApoE-/- mice induced by WD diet. The likely mechanism is the inhibition of the differentiation and recruitment of monocytes and macrophages, the promotion of the differentiation and recruitment of Treg cells, as well as the reduction of the secretion of pro-inflammatory factors.

ABSTRACT

The therapeutic effects of curcumin for polycystic ovary syndrome (PCOS) remain inconclusive. The present study aims to evaluate the effects of curcumin on glycemic control and lipid profile in patients with PCOS. PubMed, Embase, Scopus, Web of Science, and Cochrane Library were searched from the inception through 28 November 2020. Randomized control trials (RCTs), which enrolled adult patients with PCOS, compared curcumin with placebo regarding the glycemic control and lipid profile, and reported sufficient information for performing meta-analysis, were included. Three RCTs were included. Curcumin significantly improves fasting glucose (mean difference (MD): -2.77, 95% confidence interval (CI): -4.16 to -1.38), fasting insulin (MD: -1.33, 95% CI: -2.18 to -0.49), Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) (MD: -0.32, 95% CI: -0.52 to -0.12), and quantitative insulin sensitivity check index (QUICKI) (MD: 0.010, 95% CI: 0.003-0.018). It also significantly improves high-density lipoprotein (MD: 1.92, 95% CI: 0.33-3.51) and total cholesterol (MD: -12.45, 95% CI: -22.05 to -2.85). In contrast, there is no statistically significant difference in the improvement in low-density lipoprotein (MD: -6.02, 95% CI: -26.66 to 14.62) and triglyceride (MD: 8.22, 95% CI: -26.10 to 42.53) between curcumin and placebo. The results of the fasting glucose, fasting insulin, HOMA-IR, QUICKI, and total cholesterol are conclusive as indicated by the trial sequential analysis. Curcumin may improve glycemic control and lipid metabolism in patients with PCOS and metabolic abnormality without significant adverse effects. Further studies are advocated to investigate the potential effects of curcumin on hyperandrogenism.

ABSTRACT

Alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), rumenic acid (RmA), and punicic acid (PunA) are claimed to influence several physiological functions including insulin sensitivity, lipid metabolism and inflammatory processes. In this double-blind randomized controlled trial, we investigated the combined effect of ALA, DHA, RmA and PunA on subjects at risk of developing metabolic syndrome. Twenty-four women and men were randomly assigned to two groups. Each day, they consumed two eggs enriched with oleic acid (control group) or enriched with ALA, DHA, RmA, and PunA (test group) for 3 months. The waist circumference decreased significantly (-3.17 cm; p < 0.001) in the test group. There were no major changes in plasma insulin and blood glucose in the two groups. The dietary treatments had no significant effect on endothelial function as measured by peripheral arterial tonometry, although erythrocyte nitrosylated hemoglobin concentrations tended to decrease. The high consumption of eggs induced significant elevations in plasma low-density lipoprotein (LDL)- and high-density lipoprotein (HDL)-cholesterol (p < 0.001), which did not result in any change in the LDL/HDL ratio in both groups. These results indicate that consumption of eggs enriched with ALA, DHA, RmA and PunA resulted in favorable changes in abdominal obesity without affecting other factors of the metabolic syndrome.

ABSTRACT

BACKGROUND: Traditional Chinese medicine (TCM) KaiXinSan (KXS) has been used to treat depressed patients for a long time, but its potential underlying mechanisms have not been fully understood. HYPOTHESIS: KXS could mitigate symptoms of patients with atypical depression at least partly via regulating lipid equilibrium. METHODS: Patients meeting DSM-IV criteria for mild or moderate depression were assigned into placebo (N = 68) or KXS 3.2 g/day (N = 66) groups in a randomized, double-blinded, placebo-controlled, parallel clinical trial to investigate the anti-depressive efficacy of KXS and its association with serum lipid profile. RESULTS: The HAMD score and SDS score at 8 weeks were significantly improved in KXS-treated patients the N-BACK accuracy rate was also increased after 8 weeks of KXS treatment compared with baseline. These results indicated that KXS not only improved the specific symptoms of depression, but also had a beneficial effect on cognitive function related working memory. More importantly, KXS treatment improved patients' lipid profile by reducing the ratios of LDL/HDL and ApoB/ApoA1 (p < 0.05), as well as ApoC3 level. Moreover, subgroup analysis found that HAMD score was significantly higher in patients with high lipid profile than in those with normal lipid profile, and lipid improvement after 8 weeks of KXS treatment was more obvious in depressed patients with high lipid profile than with normal lipid profile. CONCLUSION: KXS could mitigate symptoms of patients with minor and modest depression at least partly via regulating lipid equilibrium. Its might shed light that KXS may likely contributes to depressed patients with other cardio-metabolic diseases.

ABSTRACT

ABSTRACT: Cystatin C has been proposed as a useful biomarker of early impaired kidney function and a predictor of mortality risk. The present study is to investigate the association between serum Cystatin C and the severity of coronary artery lesions, Gensini score (GS), and the risk of coronary artery disease (CAD).A total of 682 CAD patients (230 females, 452 males; mean age 62.6 ±â€Š10.7 years, range from 31 to 86 years) and 135 controls (41 females, 94 males; mean age 58.0 ±â€Š10.3 years, range from 38 to 84 years) were recruited in the present study. Enzyme-linked immunosorbent assay was applied to measure serum cystatin C levels and other serum indexes. The estimated glomerular filtration rate and GS were calculated.Serum low-density lipoprotein cholesterol (LDL-C), uric acid, Cystatin C, and homocysteine (HCY) were significantly elevated in CAD patients compared to controls. There were significant differences regarding total cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein, cystatin C, eGFR and GS among stable angina pectoris (SAP), unstable angina group (UAP), and acute myocardial infarction (AMI) patients. AMI group had an elevated serum Cystatin C, LDL-C, HCY, and GS than SAP and UAP patients. When stratified patient groups by the quartiles of Cystatin C, we found age, the proportion of male and patients with diabetes, HCY, and GS were increased in Q4 than in other quartile groups. Spearman correlation test revealed a positive relationship between Cystatin C, HCY, and GS. Multivariate logistic regression analysis revealed that serum Cystatin C level, presence of hypertension and diabetes, HCY, age, and male were the risk factors for coronary artery lesions.In summary, our results suggested that cystatin C is a promising clinical biomarker that provides complementary information to the established risk determinants. The serum Cystatin C level is strongly associated with GS and could be used to evaluate the severity of coronary artery lesions.

ABSTRACT

SCOPE: A main risk factor of atherosclerosis is a Western diet (WD) rich in n-6 polyunsaturated fatty acids (PUFAs) sensitive to oxidation. Their oxidation can be initiated by heme iron of red meat leading to the formation of 4-hydroxy-2-nonenal (4-HNE), a cytotoxic aldehyde. An increased 4-HNE production is implicated in endothelial dysfunction and atherosclerosis. By contrast, a diet rich in proanthocyanidins reduces oxidative stress and arterial diseases. This study evaluates the effects of a WD on vascular integrity in ApolipoproteinE (ApoE-/- ) mice and the protective capacity of apple extract and puree rich in antioxidant proanthocyanidins. METHODS AND RESULTS: ApoE-/- mice are fed during 12 weeks with a WD with or without n-6 PUFAs. Moreover, two WD + n-6 PUFAs groups are supplemented with apple puree or phenolic extract. An increase in digestive 4-HNE production associated with a rise in plasmatic 4-HNE and oxidized LDL concentrations is reported. Oxidizable n-6 PUFAs consumption is associated with a worsened endothelial dysfunction and atherosclerosis. Interestingly, supplementations with apple polyphenol extract or puree prevented these impairments while reducing oxidative stress. CONCLUSION: n-6 lipid oxidation during digestion may be a key factor of vascular impairments. Nevertheless, an antioxidant strategy can limit 4-HNE formation during digestion and thus durably protect vascular function.

ABSTRACT

Metabolic syndrome (MetS) is a combination of physiologically dysregulated parameters that can include elevated fasting blood glucose, high blood pressure, central obesity, increased triglyceride levels, insulin resistance, diabetes, elevated low density lipoprotein levels, and reduced high density lipoprotein levels in the blood. Effective clinical management of MetS is critical as it is strongly associated with long lasting and fatal complications in patients. Alongside standard care of lifestyle changes and medication, dietary supplements derived from herbal resources could be an alternative therapeutic strategy that is safe, efficient, culturally acceptable, and has few side effects. Of the dietary supplements, spicy foods have always been considered a great source of functional bioactive compounds. Herbal therapy is broadly used in many countries as a treatment or as a preventive measure in the management of MetS risk factors, including blood glucose, blood pressure, and blood lipid levels. Herein, an attempt is made to evaluate the recent studies in the management of MetS with herbal alternatives, and to explore the possibility of their use as therapeutic treatments or supplements.

ABSTRACT

The present work aimed to find out the effect of different levels of hydrolysable tannin (HT) on serum hormonal profile, biochemical indices, lipid profile, apparent digestibility of nutrients and body weight gain in healthy female rats. Forty five adult healthy female rats of 8 weeks old were randomly divided into five equal groups. Different doses of HT 0, 0.5, 1, 1.5 and 2% were administered daily to each rats group on the body weight basis for 6 weeks. The results had shown the reduction trend (p < 0.05) in the blood glucose, serum cholesterol, low density lipoprotein, testosterone, prolactin, ghrelin, total oxidative stress and serum iron levels; while an improvement (p < 0.05) was seen in serum follicle stimulating hormone, progesterone, luteinizing hormone, high density lipoprotein, IgM and total antioxidant capacity. However, no effect (p > 0.05) was noticed in serum IgG, protein, estrogen and calcium levels. A significant reduction (p < 0.05) was seen in the apparent nutrient digestibility and body weight gain. The results had shown improvement in the feed conversion ratio (p < 0.05) but non-significant decrease (p > 0.05) in the feed intake. The findings showed that HT had healthy effects on the serum biochemical indices and reproductive hormonal profile but had a negative impact on the nutrient digestibility. Thus, the study concluded that HT could be used as an herbal medicine for the treatment of leading metabolic and infertility diseases like obesity and polycystic ovarian syndrome in females.

ABSTRACT

Antiretroviral therapy (ART) increases the risk of cardiometabolic diseases in people living with HIV/AIDS (PLWHA). However, there is a lack of evidence regarding the effectiveness of a nutritional intervention on several cardiometabolic parameters in this population. Therefore, this study aimed to evaluate the effectiveness of two nutritional interventions on several cardiometabolic parameters in PLWHA treated with ART. A parallel randomized clinical trial was performed with PLWHA treated with ART. The participants (n = 88) were divided into two intervention groups: (1) nutritional counseling (n = 44) and (2) individualized dietary prescription (n = 44). The follow-up period was 30 weeks. A reduction in low-density lipoprotein (LDL) was the primary outcome. Secondary outcome variables were reductions in total cholesterol (TC), triglycerides (TG), fasting plasma glucose (FPG), systolic and diastolic blood pressures (SBP and DBP, respectively), waist circumference (WC), body mass index (BMI), and increases in high-density lipoproteins (HDL). A multiple linear regression was used to analyze the effectiveness of the interventions, adjusted for sociodemographic, lifestyle, and clinical characteristics. Sixty-two PLWHA completed the trial (nutritional counseling, n = 32; individualized dietary prescription, n = 30). At follow-up, we observed in the nutritional counseling group significant reductions in SBP (p = 0.036) and DBP (p = 0.001). Significant reductions in FPG (p = 0.008) and DBP (p = 0.023) were found in the individualized dietary prescription group. In the fully adjusted models, significant reductions in LDL, SBP, DBP, and BMI were found in the individualized dietary prescription group. In conclusion, the two investigated nutritional interventions were effective in reducing some cardiometabolic risk factors in PLWHA. However, after adjustments for covariates, the individualized dietary prescription showed significant reductions in the primary outcome and, also, in more cardiometabolic risk factors than the nutritional counseling.

ABSTRACT

Magnesium (Mg) deficiency is known to promote vascular and cardiac dysfunctions such as atherosclerosis. This study investigated the effect of oral MgSO4 therapy to improve lipid profile and serum oxidized LDL level and its receptor (LOX1) in moderate coronary atherosclerotic patients. In this randomized double-blind placebo-controlled clinical trial study, 64 patients with moderate coronary artery disease were selected according to angiography findings. Participants were divided into 2 groups including Mg-treated (n = 32) and placebo (n = 32) The patients received either placebo or MgSO4 supplement capsule, containing 300 mg MgSO4 for 6 months on a daily basis. Lipid profile, HbA1c, 2h postprandial (2hpp) blood glucose, fasting blood sugar, serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), oxidized low-density lipoprotein, and lectin-like ox-LDL receptor 1 (LOX1) concentrations were measured at baseline and every 3 months. HbA1c, serum LOX1, and oxidized low-density lipoprotein concentrations were significantly lower in the Mg-treated group than the placebo group 3 months after MgSO4 administration. 2hpp, serum low-density lipoprotein cholesterol, SGPT, SGOT levels, and HbA1c levels significantly improved in the Mg-treated group compared with the placebo-received group. Overall, the results of this study showed that magnesium treatment improved some of the major risk factors of atherosclerosis. According to the results of liver function tests (SGOT and SGPT), magnesium therapy seems to be safe in patients with moderate atherosclerotic plaque. Therefore, it is suggested that magnesium to be used along with other atherosclerosis control drugs.

ABSTRACT

Polyunsaturated fatty acids of the n-3 series (n-3 PUFA) exhibit a number of favorable effects on the human organism and it is desirable to increase their intake in the diet. For this purpose, flaxseed oil was added to a chicken-feed mixture for the production of meat and eggs. The content of n-3 PUFA in the obtained meat was increased from 250 mg (reference value) to 900 mg in 100 g of meat and from 110 mg (reference value) to 190 mg in 100 g of whole egg; the enriched products are designated as omega-3 meat and omega-3 eggs. Omega-3 meat and eggs were subsequently fed for a period of eight weeks in an amount of 480 g of meat and four eggs (228 g netto) a week to a group of 14 healthy volunteers, whose body composition parameters were measured and blood was analyzed biochemically to determine blood lipids, coagulation parameters, plasma, and erythrocyte fatty acid spectrum composition. A control group of 14 volunteers was fed normal chicken and eggs in the same regime. The performed dietary intervention increases the intake of long-chain PUFA (LC-PUFA) by 37 mg per day, which represents 7-15% of the recommended daily dose. The performed tests demonstrated that the consumption of omega-3 enriched meat and eggs significantly increases the content of n-3 PUFA in the erythrocytes, which are a long-term indicator of fatty acid intake. This intervention has no demonstrable effect on the basic body parameters, such as body weight, fat content, Body Mass Index (BMI), and also on the plasma cholesterol level, high-density lipoprotein (HDL), low-density lipoprotein (LDL), blood clotting and inflammation markers, and omega-3 index.

ABSTRACT

RATIONALE: Although there are several reports on the effect of herbal medicine on weight loss in adults, evidence supporting its efficacy and safety in obese pediatrics is insufficient. Herein, we clinically investigated the preliminary experience of community-based healthcare program in cases of childhood obesity treated with an herbal complex, Slim-diet (SD), along with lifestyle modification. PATIENT CONCERNS: Seventeen subjects with childhood obesity participated in a community-based healthcare program, which consisted of twice-a-week play type physical activity and dietary counseling program with simultaneous twice-a-day administration of SD for 4 weeks. DIAGNOSES: The data of 13 obese pediatrics (body mass index [BMI] ≥ the 95th percentile for children of the same age and sex) in their 3rd to 6th grade who finally completed at least 6 visits out of a total of 8 visits of the program including baseline and endpoint assessments were analyzed. INTERVENTIONS: Participants received 20 g of SD daily. Simultaneously, play-type physical activity program with an exercise therapist and dietary counseling with a dietitian for lifestyle modification were conducted at every visit. Body composition, blood chemistry, the Korean Youth Physical Activity Questionnaire (KYPAQ) score, and the preference for salt density and sugar content were assessed at baseline and endpoint. OUTCOMES: After SD administration, body mass index decreased from 26.74 ±â€Š2.11 kg/m to 26.50 ±â€Š2.20 kg/m (P < .05) with statistically significant increases in height, weight, and skeletal muscle mass. The results of blood chemistry and the KYPAQ score showed no significant change. The preferences for salt density were improved in 8, maintained in 2, and worsened in 3 participants and those for sugar content were improved in 6 and maintained in 7 participants with no worsening. LESSONS: In the present study, we showed the clinical effects of SD with lifestyle modification in patients with childhood obesity who participated in community-based healthcare program. Further clinical studies investigating the effects of SD are required.

ABSTRACT

Both long-term undernutrition and overnutrition disturb metabolic balance, which is mediated partially by the action of two adipokines, leptin and resistin (RSTN). In this study, we manipulated the diet of ewes to produce either a thin (lean) or fat (fat) body condition and investigated how RSTN affects endocrine and metabolic status under different leptin concentrations. Twenty ewes were distributed into four groups (n = 5): the lean and fat groups were administered with saline (Lean and Fat), while the Lean-R (Lean-Resistin treated) and Fat-R (Fat-Resistin treated) groups received recombinant bovine resistin. Plasma was assayed for LH, FSH, PRL, RSTN, leptin, GH, glucose, insulin, total cholesterol, nonesterified fatty acid (NEFA), high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol and triglycerides. Expression levels of a suppressor of cytokine signaling (SOCS-3) and the long form of the leptin receptor (LRb) were determined in selected brain regions, such as the anterior pituitary, hypothalamic arcuate nucleus, preoptic area and ventro- and dorsomedial nuclei. The results indicate long-term alterations in body weight affect RSTN-mediated effects on metabolic and reproductive hormones concentrations and the expression of leptin signaling components: LRb and SOCS-3. This may be an adaptive mechanism to long-term changes in adiposity during the state of long-day leptin resistance.

ABSTRACT

Recent studies point out that not only the daily intake of energy and nutrients but the time of day when they are ingested notably regulates lipid metabolism and cardiovascular risk (CVR). Therefore, the aim of the study was to assess if the type of fat ingested at breakfast can modify lipid metabolism in women with CVR. A randomized, crossover clinical trial was performed. Sixty volunteers were randomly assigned to a (A) polyunsaturated fatty acid (PUFA)-rich breakfast, (B) saturated fatty acid (SFA)-rich breakfast, or (C) monounsaturated fatty acid (MUFA)-rich breakfast. Plasma lipoprotein and apolipoprotein subfractions were determined. Our data showed that the PUFA-rich breakfast decreased lipoprotein (a) (Lp(a)), very low-density lipoproteins (VLDL), and intermediate-density lipoproteins (IDL), and increased high-density lipoproteins (HDL). A similar trend was observed for the MUFA-rich breakfast, whereas the SFA-rich breakfast, although it decreased VLDL, also increased IDL and reduced HDL. The PUFA-rich breakfast also decreased ß-lipoproteins and apolipoprotein-B. In summary, varying the type of fat eaten at breakfast is enough to significantly modify the lipid metabolism of women with CVR, which can be of great relevance to establish new therapeutic strategies for the treatment of these subjects.

ABSTRACT

BACKGROUND AND AIM: Kratom, or Mitragyna speciosa Korth., is a tropical plant that has been reported to exhibit opioid-like effects. Although opioids have been demonstrated to alter the lipid profile of regular users, data on the lipid-altering effects of kratom are scarce. This study aimed to compare the fasting lipid profile of regular kratom users to that of healthy subjects who do not use kratom. It also determined the association between various characteristics of kratom users and the serum triglycerides, total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels of regular kratom users. METHODS: A total of 200 participants (n = 100 kratom users and n = 100 healthy subjects who do not use kratom) were recruited for this analytical cross-sectional study. Data on sociodemographic status, kratom use characteristics, cigarette smoking, physical activity, body mass index (BMI), fasting serum lipid profile, and liver function were collected from all participants. RESULTS: The liver parameters of the study participants were within normal range. The serum total cholesterol and LDL of kratom users were significantly lower than those of healthy subjects who do not use kratom. There were no significant differences in the serum triglyceride and HDL levels. However, higher average daily frequency of kratom use and increasing age were associated with increased serum total cholesterol among kratom users. Other kratom use characteristics such as age of first kratom intake, duration of kratom use, and quantity of daily kratom intake were not associated with increased serum triglyceride, total cholesterol, LDL, and HDL levels. CONCLUSIONS: Our findings suggest regular kratom consumption was not linked to elevated serum lipids, except when there is a higher frequency of daily kratom intake. However, the study was limited by the small sample size, and hence a more comprehensive study with larger sample size is warranted to confirm the findings.
