We systematically reviewed randomized clinical trials (RCTs) to elucidate the overall effects of flaxseed oil consumption on blood pressure (BP) in patients with metabolic syndrome and related disorders. PubMed, Scopus, Cochrane Library, and ISI Web of Science databases were systematically searched until March 31, 2020, to find RCTs that examined the effect of flaxseed oil consumption on BP. Weighed mean difference (WMD) was pooled using a random‐effects model. Standard methods were used for the assessment of heterogeneity, sensitivity analysis, and publication bias. Meta‐analysis of five trials (6 arms) showed significant reductions in systolic (WMD: −3.86 mmHg, 95% CI: −7.59 to −0.13, p = .04) BP (SBP) after flaxseed oil consumption. However, the overall effect illustrated no significant change in diastolic (WMD: −1.71 mmHg, 95% CI: −3.67 to 0.26, p = .09) BP (DBP) in the intervention group compared with the control group. Our findings revealed that flaxseed oil consumption has favorable effects on SBP in patients with metabolic syndrome and related disorders. However, further investigations are needed to provide more reliable evidence.
This study aimed to evaluate the effects of licorice root supplementation on liver enzymes, hepatic steatosis, metabolic and oxidative stress parameters in women with nonalcoholic fatty liver disease (NAFLD). In this randomized double‐blind, placebo‐controlled trial, 60 women with NAFLD were selected and randomly assigned into 2 groups to take 1,000 mg/day powder of licorice root extract or placebo for 12 weeks. In addition, all the patients were advised to follow a weight loss diet and healthy lifestyle. The plasma levels of liver enzymes, glycemic indices, lipid profile, oxidative stress parameters, as well as hepatic steatosis were measured at the beginning and end of the study. Through the 12‐weeks period of supplementation, women who received powder of licorice root experienced a statistically significant improvement in alanine aminotransferase (p < .001), insulin (p = .002), insulin resistance (p = .003), malondialdehyde (p < .001) serum levels, and ultrasonographic findings of liver steatosis (p < .001), compared to the placebo group. In conclusion, licorice root supplementation in addition to gradual weight loss and lifestyle modification is superior to lifestyle modification alone for the treatment of NAFLD.
BACKGROUND: Pencak Silat is a self-defense exercise originated from Indonesia and categorized as a high-intensity exercise.
AIM: This research was intended to identify the acute response of Pencak Silat basic exercise toward interleukin-6 (IL-6) as an immune system biomarker on students of Perguruan Pencak Silat Perisai Diri Tulungrejo, Bojonegoro.
METHODS: A number of 26 students (10 boys and 16 girls) of Perguruan Pencak Silat Tulungrejo, Bojonegoro, were participated in this study. The students did the 2 h Perguruan Pencak Silat Perisai Diri, Bojonegoro, training program with 75–85% intensity. The IL-6 serum was measured using ELISA method.
RESULTS: The result of this study showed that the IL-6 serum level in post-2 (12 h after training) (6.2981 pg/mL) was higher compared with the IL-6 serum level in post-1 (shortly after training) (6.11981 pg/mL) and before training (4.5146 pg/mL). The result also showed that there was a significant difference of IL-6 levels between pre-training and after training.
CONCLUSION: This study concluded that the basic exercise performed by the new students of Perguruan Pencak Silat Perisai Diri increased IL-6 serum level.
BackgroundShorter telomere length is associated with numerous comorbidities. Several studies have investigated the role of obesity in telomere shortening. In the current systematic review and meta-analysis, we summarized the results of studies that evaluated the association between obesity and telomere length.MethodsA systematic search from Scopus, PubMed, Embase, and ProQuest electronic databases up to 19 March 2021 without language restriction was performed and after data extraction and screening, 19 manuscripts were eligible to be included in the final meta-synthesis.ResultsThe highest category of telomere length was associated with an approximate 0.75 kg/m2 reduction in body mass index (BMI; WMD = −0.75 kg/m2; CI = −1.19, −0.31; p < 0.001; I2 = 99.4%). Moreover, overweight/obese individuals had 0.036 kbp shorter telomere length compared with non-overweight/obese adults (WMD = −0.036; CI = −0.05, −0.02; p = 0.030; I2 = 100%). According to the results of subgroupings, continent, age, and sample size could be possible sources of heterogeneity.ConclusionFrom the results, it was clear that obesity was associated with shorter telomere length. Because of the observational design of included studies, the causality inference of results should be done with caution; thus, further longitudinal studies are warranted for better inference of causal association.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
