Introduction: Hypertension is a chronic condition that might lead to renal and cardiovascular diseases. The previous trials examining the effect of cinnamon supplementation on blood pressure have led to conflicting results. The present systematic review aimed to summarize the effect of cinnamon supplementation on blood pressure using a meta-analysis of published randomized controlled clinical trials. Methods: To identify the eligible articles, MEDLINE, SCOPUS, ISI Web of Science, and Google Scholar were searched from inception until September 2019 for relevant articles. The risk of bias assessment was performed using the Cochrane collaboration tool. A Random-effects model was applied to calculate the summary effects. Results: Totally, 11 trials with 686 participants were included in this systematic review and meta-analysis. The dose of cinnamon supplement consumption varied from 500 to 10000 mg/d. The meta-analysis revealed that cinnamon supplementation significantly decreases systolic blood pressure (SBP) [WMD (weighted mean difference)= -5.72 mmHg, 95% confidence interval (CI): -8.63 to -2.80; P<0.001, I2= 81.1)] and diastolic blood pressure (DBP) (WMD= -4.06 mmHg, 95% CI: -6.68 to -1.44; P= 0.002, I2 = 88.6). Subgroup analysis suggested no significant reduction of DBP in subjects with diabetes (WMD= -2.015 mmHg, 95% CI: -4.55 to 0.52; P= 0.12, I2 = 72.3) and prediabetes or metabolic syndrome (WMD= -4.8 mmHg, 95% CI: -10.06 to 0.44; P= 0.073, I2= 92.5). Conclusions: Cinnamon supplementation could be beneficial in lowering SBP and DBP in adults. Further studies with different doses are recommended to confirm the present findings.

ABSTRACT BACKGROUND Intervention studies suggest that incorporating walnuts into the diet may improve blood lipids without promoting weight gain. OBJECTIVE We conducted a systematic review and meta-analysis of controlled trials evaluating the effects of walnut consumption on blood lipids and other cardiovascular risk factors. Design We conducted a comprehensive search of PubMed and EMBASE databases (from database inception to January 2018) of clinical trials comparing walnut-enriched diets with control diets. We performed random-effects meta-analyses comparing walnut-enriched and control diets for changes in pre-post intervention in blood lipids (mmol/L), apolipoproteins (mg/dL), body weight (kg), and blood pressure (mm Hg). RESULTS Twenty-six clinical trials with a total of 1059 participants were included. The following weighted mean differences (WMDs) in reductions were obtained for walnut-enriched diets compared with control groups: −6.99 mg/dL (95% CI: −9.39, −4.58 mg/dL; P < 0.001) (3.25% greater reduction) for total blood cholesterol (TC) and −5.51 mg/dL (95% CI: −7.72, −3.29 mg/dL; P < 0.001) (3.73% greater reduction) for low-density lipoprotein (LDL) cholesterol. Triglyceride concentrations were also reduced in walnut-enriched diets compared with control [WMD = −4.69 (95% CI: −8.93, −0.45); P = 0.03; 5.52% greater reduction]. More pronounced reductions in blood lipids were observed when walnut interventions were compared with American and Western diets [WMD for TC = −12.30 (95% CI: −23.17, −1.43) and for LDL = −8.28 (95% CI: −13.04, −3.51); P < 0.001]. Apolipoprotein B (mg/dL) was also reduced significantly more on walnut-enriched diets compared with control groups [WMD = −3.74 (95% CI: −6.51, −0.97); P = 0.008] and a trend towards a reduction was observed for apolipoprotein A [WMD = −2.91 (95% CI: −5.98, 0.08); P = 0.057]. Walnut-enriched diets did not lead to significant differences in weight change (kg) compared with control diets [WMD = −0.12 (95% CI: −2.12, 1.88); P = 0.90], systolic blood pressure (mm Hg) [WMD = −0.72 (95% CI: −2.75, 1.30); P = 0.48], or diastolic blood pressure (mm Hg) [WMD = −0.10 (95% CI: −1.49, 1.30); P = 0.88]. Conclusions Incorporating walnuts into the diet improved blood lipid profile without adversely affecting body weight or blood pressure.

Abstract BackgroundSystemic arterial hypertension (HTN) is the leading risk factor of cardiovascular disease death. Lifestyle changes are key for the prevention and management of HTN. Regular aerobic exercise training is recommended as part of the management of HTN; and dynamic resistance exercise should be prescribed as an adjuvant to aerobic training. Recent evidence points to potential benefits of isometric resistance training in reducing blood pressure (BP). Yet, the hypotensive effect of isometric exercise in pre-hypertensive and hypertensive individuals is not fully understood. Thus, we will examine the effect of isometric exercise in pre-hypertensive and hypertensive individuals through a systematic review and meta-analysis. MethodsOur systematic review study will include randomized clinical trials (RCTs) selected from the electronic databases MEDLINE (PubMed), Cochrane, LILACS, EMBASE and PEDro published in English, Spanish and Portuguese language. We will follow the PRISMA guidelines and PICOS framework. Our search will involve studies with both male and female participants aged 18 years or more diagnosed with prehypertension or HTN performing one session of isometric exercise (acute effect) or isometric exercise training (chronic effect) compared to a control group (no exercise). We will use Cochrane Risk of Bias 2 (RoB 2) tool to evaluate the quality of the studies and RStudio software (v1.3.959 for Windows) for statistical analyses. DiscussionA meta-analysis of a homogeneous sample of pre-hypertensive and hypertensive individuals involving isometric handgrip exercise alone can further support previous findings and improve our understanding and recommendations for the management of these populations. Systematic review registrationThe study protocol for this review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) (CRD 42020213081).

Abstract Objective: To analyze, through a systematic review with meta-analysis, the effects of aerobic training with and without progression on systolic blood pressure (SBP) and diastolic blood pressure (DBP) in hypertensive adults.Method: The search for the studies was carried out in the PubMed, Cochrane Central, SPORTDiscus and LILACS databases. Clinical trials that analyzed the effect of aerobic training, lasting at least six weeks, on blood pressure in hypertensive individuals comparing with a control group without intervention were selected. The selection of studies and data extraction were carried out independently by two pairs of researchers. Results: Of the 13028 studies found, 24 were selected and included in this review. There was a reduction in SBP after aerobic training with progression (-10.67 mmHg; 95% CI -15.421, -5.926; p <0.001) and without progression (-10.17 mmHg; CI -12.213, -8.120; p <0.001). DBP also decreased after aerobic training with progression (-5.49 mmHg; 95% CI -8.663, -2.310; p <0.001) and without progression (-6.51 mmHg; 95% CI -9.147, -3.868; p < 0.001). Conclusion: Aerobic training promotes a reduction in the SBP and DBP levels of adults with hypertension, regardless of whether or not the training variables progression.
