Abstract [+]
Background
Genetic polymorphisms that affect the availability and secretion of dopamine can affect the risk of obesity.
Objectives
To investigate the relationship between pediatric obesity and cardiovascular risk factors (CRF) with the polymorphisms of “Fat Mass and Obesity Associated” (FTO) rs9939609, “Dopamine Receptor type 2” (DRD2) rs6277 and “Ankyrin Repeat and Kinase Domain Containing 1” (ANKK1) rs18000497 genes.
Methods
Case-Control study conducted with 226 pediatric patients from 5 to 16-years of age. The two main groups, Obese (O) and Eutrophic (E), were subdivided according to the value of HOMA-IR into obese with insulin resistance (ORI) or insulin sensitivity (OSI) and eutrophic resistant (ERI) or sensitive (ESI) to insulin. According to the presence of two or more CRF, they were subdivided into metabolically unhealthy or metabolically healthy groups: Obese Metabolically Unhealthy (OMU), Obese Metabolically Healthy (OMH), Eutrophic Metabolically Unhealthy (EMU) and Eutrophic Metabolically Healthy (EMH). Polymorphisms were determined by real-time Polymerase Chain Reaction (PCR) or Restriction Fragment Length Polymorphisms (PCR-RFLP).
Results
In the obese group, the higher the number of risk alleles of FTO and ANKK1 genes isolated and the three genes combined, the higher the mean BMI (p<0.0001). Regarding the FTO gene: the frequency of the risk allele was: 57.7%-ERI, 37.4%-ESI (p=0.048), and the homozygous wild genotype was: 29.5%-OMU, 37.5%-OMH (p=0.02). Regarding the DRD2 gene: the genotypes with the risk allele were present in 84.6%-OMU and 67.5%-OMH (p=0.031). Regarding the ANKK1 gene: the frequency of the homozygous risk genotype was current in 15.4%-ERI and 13.5%-ESI (p<0.0001) and 62.5%-EMU and 41.5%-OMH (p=0.031). Conclusion Risk alleles of FTO, DRD2 and ANKK1 genes had an additive effect on the outcome of pediatric obesity in Brazilian children and conferred a higher risk of insulin resistance (FTO and ANKK1) and CRF.

Abstract [+]
Background
Obesity is a public health concern in many countries. Obesity is often accompanied by other diseases and, in addition to its effects on personal health, also increases national health expenditure and medical costs. Currently, weight loss can be achieved through several medical means, such as gastric bypass surgery, liposuction, or the use of weight loss drugs. However, these options may lead to side effects or increased mortality. As such, the development of anti-obesity supplements that are natural and safe merits greater research attention. Garcinia cambogia extract, green coffee bean extract, mulberry leaf extract, chromium yeast, and wakame
extract are known to have the potential to combat obesity and adjust physical constitutions; however, the effect on fat loss of these agents in a compound supplement has not been researched or discussed.
Objective
This study investigated the effects of a compound supplement (hereafter referred to as Garcinia cambogia compounded supplements (GC)) containing Garcinia cambogia extract, green coffee bean extract, mulberry leaf extract, chromium yeast, and wakame extract on fat accumulation induced by a high energy (HE) diet in rats.
Design
Six-week-old, male Sprague–Dawley rats were assigned to a control group or an experimental (HE) group. The control group comprised 12 rats who were given regular feed. The HE group comprised 36 rats who were given HE diet and were further divided according to whether they received carboxymethyl cellulose (CMC) or GC (305 and 1220 mg/kg, denoted as GC-L and GC-H,
respectively) for 5-weeks. Starting from the sixth-week, the rats were tube-fed various dosages of GC. After the ninth-week, the rats’ body weight, food intake, body fat mass, serum biochemical properties, and liver fat were analyzed.
Results
The results demonstrated that the HE+GC-L rats had significantly lower weight and body fat mass (569.5±51.3 g; 36.6±9.6 g) than the HE+CMC rats (618.5±57.1 g; 46.3±12.2 g). Food efficiency and calorie utilization were also significantly lower in the HE+GC-L rats than in the HE+CMC group (p<0.01). Compared with the HE+CMC group, food efficiency, calorie utilization, total cholesterol, low-density lipoprotein cholesterol (LDL-C), and concentration of free fatty acids were also significantly lower in the HE+GC-H rats (p<0.05). Conclusion The GC supplementation significantly reduced body weight, body fat mass, body fat percentage, food efficiency, and calorie utilization in rats, and it thus has potential as a natural and safe plant extract dietary supplement. Its long-term effects on the human body should be investigated in the future.

Abstract [+]
Background
Soluble fiber has been shown to improve glycemic control by slowing the absorptions of glucose. And inositol has been shown to improve glycemic control in type 2 diabetes (T2D) and gestational diabetes via recruiting glucose transporter type 4 (GLUT4) to cell surface. However, neither inositol supplementation nor combination of inositol and soluble fiber supplementation has been studied in overweight.
Objective
To investigate if supplementation of inositol improves biological markers of glycemic control overweight and obesity, and that supplementation of inositol in combination with soluble fiber have synergistic effects to further improve these markers.
Design
A single cohort, uncontrolled, test-retest design was planned to be implemented over 5-weeks in which the participants supplemented 2 grams of myo-inositol twice daily for 4-weeks and then 2 grams of myo-inositol plus 2 grams of soluble fiber each twice daily for 1-week in overweight and obese subjects. Only one overweight subject was able to complete both phases of supplementation due to coronavirus disease-2019 (COVID-19), therefore the study is reported as a case study.
Results
Supplementation of 4 grams of myo-inositol daily for 4-weeks resulted in improved glucose parameters and lipid parameters including fasting blood glucose, post-prandial blood glucose, total blood cholesterol level, blood high-density lipoprotein (HDL) cholesterol level, and blood triglyceride level. The combination of inositol and soluble fiber supplementation further improved
the total blood cholesterol level.
Conclusion
These results indicate there is potential benefit of inositol supplementation for sub-clinical hyperglycemic, overweight subjects on glycemic control.

Abstract [+]
Aim: Obesity is increasing globally by leaps and bounds and thus the incidence of type 2 diabetes mellitus (T2DM) along with it so much so that the term diabesity had to be coined. Earlier we had reviewed how to treat the both together and the role of empagliflozin to improve cardiovascular outcome trials (CVOT). Similarly T2DM and hypertension are pathophysiologically-related diseases which co-exist with a broader complex of metabolic diseases which co-exist possessing similar set of risk factors. Hence it is important to consider which antihypertensives are suitable that possess a positive effect on metabolic factors in cases of T2DM who require an antihypertensive.
Method: A systematic review was carried out using the PubMed search engine with the MeSH terms: “T2DM”; “essential hypertension; “cardiovascular (CV)”; “Complications of diabetes mellitus (DM) and antihypertensive”; “Antihypertensive preferred in T2DM subjects”; “Renin-angiotensin–aldosterone system inhibitors”; “Angiotensin converting enzyme inhibitors (ACEi)”; “Angiotensin receptor blockers (ARBs)”; “Dihydropyridine calcium channel blocker”; “β2 blockers”; “Diuretics”.
Discussion: Most diabetes mellitus (DM) subjects need a minimum of two antihypertensive drugs, combining a renin-angiotensinaldosterone system (RAS) inhibitor with a dihydropyridine calcium channel blocker seems to be the most indicated approach. But not all dihydropyridine calcium channel blockers have equivalent effects on metabolic parameters. Hence manidipine that causes positive effect on insulin resistance (IR) seems to be an effective option. We have reviewed how manidipine is superior to amlodipine with regards to improving IR, not seen with amlodipine, along with not causing excessive sympathetic nervous system (SNS) activation, pulse pressure and ankle edema or to much lesser extent than amlodipine. Therefore, manidipine needs to be the first addition to RAS inhibitors in case of DM’s having hypertension of the dihydropyridines calcium channel blockers. Further good blood pressure (BP) control been correlated with good CVs outcomes.
Conclusion: A RAS inhibitor is the first line of choice of drugs in a subject with T2DM who needs to be treated with empagliflozin for better CVOT outcome, and when a 2nd drug has to be added it is manidipine that is preferred over amlodipine. Plant products are proving to be having a lot of beneficial effects in DM, obesity and hypertension. Thus need for developing agents from plants will prove to be more cost effective in these chronic diseases where compliance is difficult to achieve with the use of common antiDM drugs and antihypertensives with the cost factor along with their side effects.

Abstract [+]
Purpose
Internet addiction is a major health concern among undergraduate students; however, few studies have addressed modifiable behavioural factors associated with internet addiction in the context of Taiwan. This study aimed to investigate associations between physical activity and the risk of internet addiction among undergraduate students in Taiwan.
Methods
In 2017, we recruited 320 undergraduate students from Northern Taiwan to participate in a cross-sectional questionnaire-based survey. Physical activity was measured by the Taiwanese short-form version of the International Physical Activity Questionnaire, which evaluates an individual’s weekly levels of vigorous-intensity aerobic physical activity (VPA) and moderate-intensity aerobic physical activity (MPA). Internet addiction was measured by the Chen Internet Addiction Scale (CIAS).
Results
For the 320 surveyed students, the average CIAS score was 53.3, and 18.13% of participants were at risk for internet addiction (defined as CIAS score >64). The results of the multiple regression analysis indicated that a routine of at least 150 min of MPA per week was negatively associated with risk for internet addiction (β=−4.39, 95% CI=[-8.10, -0.66]). No significant associations were observed between internet addiction and 75 min of VPA or 150 min of total physical activity per week. Among the 5 dimensions of the CIAS scale, MPA was negatively associated with tolerance symptoms, time-management problems, and interpersonal and health-related problems when a routine of 150 min per week was adopted.
Conclusion
A routine of 150 min of MPA per week was associated with a lower risk for internet addiction. Intervention efforts aimed at reducing undergraduate students’ problematic internet use should promote recommended levels of MPA. We also recommend longitudinal research on the effects of engaging in physical activity on the risk of internet addition.

The Effect of L-Carnitine, Green Tea Extract and Lotus Leaf Extract on the Body Fat Percentage in High Energy Diet-Induced Obese Rats
PDF 365.20 KB
Full-Text (HTML)
Abstract [+]
Background
Obesity has become a public health issue of global concern. Obesity is often associated with the occurrence of many diseases, and will also increase mortality; it not only affects personal health, but also increases healthcare costs, thus reducing social productivity and causing negative social and economic impacts. Therefore, ameliorating obesity is an issue worth attention and effort. The development of a natural and safe anti-obesity combination is worthy of further research. It is known that L-carnitine, green tea and lotus leaves have anti-obesity potential, but there is no research and discussion on this novel combination to improve body fat.
Objective
This study explored how the dietary supplement formula containing L-carnitine, green tea extract and lotus leaf extract (CGL) lowered the body fat accumulation in rats induced by high-energy diet.
Design
The test used 60-week-old male Sprague Dawley® white rats, which were first divided into the control group (12 rats were given normal feed) and the experimental group (48 rats were given high energy diet; HE). The HE group was further divided into H2O and CGL groups (296, 593 and 1186 mg/kg, to be designated as CGL-L, CGL-M, CGL-H respectively). The rats were first fed with feed for five-weeks, and then fed with different doses of CGL by gavage starting from the sixth-week. After nine-weeks of feeding, the rats were sacrificed to obtain their body weight, feed intake, body fat, serum biochemical indices and liver lipid measurements.
Results
The results show that the final body weight of HE+CGL-L (578.8±41.6 g) was significantly lower than that of HE+H2O (634.9±42.2 g), and the body fat amount of HE+CGL-L (36.6±9.8 g) was significantly lower than that of HE+H2O (49.4±13.8 g). Feed efficiency and calorie efficiency of HE+CGL-L were also significantly lower than that of HE+H2O (p<0.001). HE+CGL-M and HE+CGL-H were also able to significantly reduce the final body weight, body fat amount and serum-free fatty acid concentration (p<0.05).
Conclusion
CGL can significantly reduce the final body weight, body fat amount, body fat ratio, feed efficiency and calorie efficiency. CGL has the potential as a new dietary supplement for weight loss. However, the significance of these results on humans taking the supplement for prolonged periods of time is unknown and should be a focus for future investigations.
