Meta-Analysis
Effects of combined aerobic and resistance training on glycemic control, blood pressure, inflammation, cardiorespiratory fitness and quality of life in patients with type 2 diabetes and overweight/obesity: a systematic review and meta-analysis.
BACKGROUND
Structured aerobic or resistance training alone seems to be a beneficial tool for improving glucose homeostasis, chronic systemic inflammation, resting cardiovascular function, and mental health in people with obesity and type 2 diabetes mellitus (T2DM). The aim of the present study was to synthesize the available data on the effectiveness of combined aerobic and resistance training (CART) on glycemic control, blood pressure, inflammation, cardiorespiratory fitness (CRF), and quality of life (QoL) in overweight and obese individuals with T2DM.
METHODS
A database search was carried out in PubMed, Web of Science, Scopus, Science Direct, Cochrane Library, and Google Scholar from inception up to May 2023. The Cochrane risk of bias tool was used to assess eligible studies, and the GRADE method to evaluate the reliability of evidence. A random-effects model was used, and data were analyzed using standardized mean differences and 95% confidence intervals. The study protocol was registered in the International Prospective Register of Systematic Reviews (ID: CRD42022355612).
RESULTS
A total of 21,612 studies were retrieved; 20 studies were included, and data were extracted from 1,192 participants (mean age: 57 ± 7 years) who met the eligibility criteria. CART demonstrated significant improvements in body mass index, glycated hemoglobin, systolic and diastolic blood pressure, C-reactive protein, tumor necrosis factor-alpha, interleukin-6, CRF, and QoL compared to ST. These findings highlight the significance of exercise interventions such as CART as essential elements within comprehensive diabetes management strategies, ultimately enhancing overall health outcomes in individuals with T2DM and overweight/obesity.No differences were found in resting heart rate between CART and ST. An uncertain risk of bias and poor quality of evidence were found among the eligible studies.
CONCLUSION
These outcomes show clear evidence considering the positive role of CART in inducing beneficial changes in various cardiometabolic and mental health-related indicators in patients with T2DM and concurrent overweight/obesity. More studies with robust methodological design are warranted to examine the dose-response relationship, training parameters configuration, and mechanisms behind these positive adaptations.

Endothelial dysfunction indicates blood vessel injury and is a risk factor for cardiovascular diseases. Blueberry has been approved for its benefits on human health, especially on cardiovascular function. However, its effect on endothelial function remains unclear. We conducted a systematic review and meta-analysis to explore the impact of blueberries on endothelial function in adults. We searched PubMed, Web of Science, Embase, and the Cochrane Library, 16 studies were included in the systematic review, and 11 were used for the meta-analysis. Data associated with endothelial function were extracted and pooled as mean differences (MD) with 95% confidence intervals (CI). Blueberry consumption significantly improved flow-mediated dilation (FMD) by 1.50% (95% CI: 0.81, 2.20; I = 87%) and reactive hyperemia index (RHI) by 0.26 (95% CI: 0.09, 0.42; I = 72%). A significant decrease in diastolic blood pressure (DBP) was also observed (MD: -2.20 mm Hg; 95% CI: -4.13, -0.27; I = 11%). Subgroup analysis indicated a significant decrease in blood pressure (Systolic blood pressure [SBP]: -3.92 mmHg; 95% CI: -6.88, -0.97; I = 20% and DBP: -2.20 mmHg; 95% CI: -4.13, -0.27; I = 11%) in the smoking population. However, SBP levels (MD: -1.43 mm Hg; 95% CI: -3.11, 0.26; I = 20%) and lipid status (high-density lipoprotein cholesterol [HDL-C]: 0.06; 95% CI: -0.04, 0.16; I = 77%; low-density lipoprotein cholesterol [LDL-C]: 0.05; 95% CI: -0.14, 0.24; I = 0%) did not significantly improve. Blueberry intervention improved endothelial function and DBP. Subgroup analysis revealed a notable improvement in blood pressure among the smoking population. However, no significant effects were observed on SBP, HDL-C, and LDL-C levels. Future research should delve into the mechanisms of endothelial improvement and verify blood pressure reduction in specific subpopulations through large-scale trials. https://www.crd.york.ac.uk/PROSPERO/, Identifier CRD42023491277.

Meta-Analysis
OBJECTIVE
This study aimed to distinguish between healthy controls and patients with OSAHS regarding homocysteine (HCY) levels and investigate how individuals with OSAHS respond to continuous positive airway pressure ventilation (CPAP) in terms of serum and plasma HCY levels.
METHODS
To ascertain published articles about OSAHS, an exhaustive search was performed across medical databases, encompassing PubMed, Web of Science, EMBASE, CNKI, and Cochrane Library, until January 2, 2024. This study reviewed the literature regarding HCY levels in individuals with OSAHS and control groups, HCY levels under pre- and post-CPAP treatment, the Pearson/Spearman correlation coefficients between HCY levels and apnea-hypopnea index (AHI), and the hazard ratio (HR) of HCY levels concerning the occurrence of major adverse cerebrocardiovascular events (MACCEs) in patients with OSAHS. Meta-analyses were performed using weighted mean difference (WMD), correlation coefficients, and HR as effect variables. The statistical analysis was conducted using the R 4.1.2 and STATA 11.0 software packages.
RESULTS
In total, 33 articles were selected for the final analysis. The OSAHS group exhibited significantly higher serum/plasma HCY levels than the control group (WMD = 4.25 μmol/L, 95% CI: 2.60-5.91, < 0.001), particularly among individuals with moderate and severe OSAHS. Additionally, subgroup analysis using mean age, ethnicity, mean body mass index, and study design type unveiled significantly elevated levels of HCY in the serum/plasma of the OSAHS group compared to the control group. CPAP treatment can significantly decrease serum/plasma HCY levels in patients with OSAHS. Moreover, elevated HCY levels in individuals with OSAHS could be one of the risk factors for MACCEs (adjusted HR = 1.68, 95% CI = 1.10-2.58, = 0.017). AHI scores show a positive correlation with serum/plasma HCY levels.
CONCLUSION
Patients with OSAHS had elevated serum/plasma HCY levels compared to healthy controls; however, CPAP therapy dramatically decreased HCY levels in patients with OSAHS. In patients with OSAHS, elevated HCY levels were linked with an increased risk of MACCEs, and HCY was positively connected with AHI values. HCY levels may serve as a useful clinical indicator for determining the severity and efficacy of OSAHS treatments.

Meta-Analysis Review
Community-Based Strategies to Improve Health-Related Outcomes in People Living With Hypertension in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis.
BACKGROUND
Individuals living with hypertension are at an increased risk of cardiovascular- and cerebrovascular-related outcomes. Interventions implemented at the community level to improve hypertension control are considered useful to prevent cardiovascular and cerebrovascular events; however, systematic evaluation of such community level interventions among patients living in low- and middle-income countries (LMICs) is scarce.
METHODS
Nine databases were searched for randomized controlled trials (RCTs) and cluster randomized control trials (cRCTs) implementing community level interventions in adults with hypertension in LMICs. Studies were included based on explicit focus on blood pressure control. Quality assessment was done using the Revised Cochrane Risk of Bias tool for randomized trials (ROBS 2). Results were presented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Fixed-effect meta-analyses were conducted for studies that reported continuous outcome measures.
RESULTS
We identified and screened 7125 articles. Eighteen studies, 7 RCTs and 11 cRCTs were included in the analysis. The overall summary effect of blood pressure control was significant, risk ratio = 1.48 (95%CI = 1.40-1.57, n = 12). Risk ratio for RCTs was 1.68 (95%CI = 1.40-2.01, n = 5), for cRCTs risk ratio = 1.46 (95%CI = 1.32-1.61, n = 7). For studies that reported individual data for the multicomponent interventions, the risk ratio was 1.27 (95% CI = 1.04-1.54, n = 3).
DISCUSSION
Community-based strategies are relevant in addressing the burden of hypertension in LMICs. Community-based interventions can help decentralize hypertension care in LMIC and address the access to care gap without diminishing the quality of hypertension control.

Review
Hemodynamic management, specifically blood pressure, is essential to reduce mortality and preserve functional capacity. However, the literature is uncertain about the best blood pressure target to be adopted after performing mechanical thrombectomy in patients with acute ischemic stroke. Randomized clinical trials that compared blood pressure goals after mechanical thrombectomy were searched in the following databases: MEDLINE/PubMed, Embase, Scopus, Biomedcentral, and Cochrane Library. The last search was on September 19, 2023. The results obtained were used to construct network meta-analyses. A total of 1556 participants were enrolled from 4 randomized controlled trials (OPTIMAL-BP, ENCHANTED2/MT, BP-TARGET, BEST-II). The last article was not included in the network meta-analysis because it did not have common blood pressure targets. The outcomes compared were: mRS (modified Rankin scale), eTICI/mTICI scale scores, symptomatic and any intracerebral hemorrhage, post-intervention NIHSS, and post-intervention infarct volume. The outcomes using the mRS scale showed that better outcomes were reached with less intensive blood pressure targets when comparing < 120 mmHg vs. ≤ 180 mmHg, OR: 0.71 (95% CI 0.54 - 0.94), in the outcome of mRS 0-1. And for the mRS 0-2 outcome with comparisons < 120 mmHg vs. ≤ 180 mmHg, with OR: 0.59 (95% CI 0.44 - 0.77) and < 140 mmHg vs. ≤ 180 mmHg, with OR: 0.61 (95% CI 0.41 - 0.89). In patients with large vessel occlusion treated with mechanical thrombectomy and who achieved good reperfusion, intensive blood pressure lowering is not effective and might be harmful respect to non intensive blood pressure control in recanalized patients.

Meta-Analysis
BACKGROUND
Cardiovascular disease (CVD) is the leading cause of mortality in the world. Patients with periodontitis have a higher risk of CVD, although a causal relationship between these conditions remains unclear. Non-surgical periodontal therapy (NSPT) is able to control inflammation at local and systemic levels. This study aimed to analyze the effect of NSPT on CVD risk markers.
METHODS
Four electronic databases were searched from their inception to April 1, 2023, to identify and select articles without any language restrictions. Eleven CVD-related markers (e.g., C-reactive protein [CRP], Interleukin-6 [IL-6]) were selected. Meta-analyses were performed using random and fixed effect models. The differences were expressed as weighted mean differences (WMD) and 95% confidence interval (95% CI).
RESULTS
From 1353 studies, twenty-one randomized controlled clinical trials were included in the meta-analysis. Results showed a significant decrease in CRP, IL-6, and systolic blood pressure (SBP) after NSPT.
CONCLUSION
Moderate certainty evidence shows that NSPT has a positive effect on the reduction of IL-6 and SBP in patients with periodontitis, while low certainty evidence shows that NSPT is effective for reduction of CRP. Moderate certainty evidence showed that NSPT did not show a positive effect on low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC) and triglycerides (TG), and low certainty evidence showed that NSPT did not show a positive effect on Interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNF-α), diastolic blood pressure (DBP), and flow-mediated dilatation (FMD).
PROTOCOL REGISTRATION
The protocol was registered in the PROSPERO (International Prospective Register of Systematic Reviews), number CRD42022377565.

Review
Nature-based interventions (NBIs) are activities, strategies, or programs taking place in natural settings, such as exercising in greenspaces, to improve the health and well-being of people by integrating the benefits of nature exposure with healthy behaviours. Current reviews on NBIs do not report the effects on different groups of physical health conditions. The purpose of this systematic review and meta-analysis was to identify and synthesize the evidence of the effect of NBIs on physical health outcomes and biomarkers of physical health conditions. Overall, 20,201 studies were identified through searching MEDLINE, Embase, CINAHL, SPORTDiscus, and CENTRAL databases up to June 7, 2024. Inclusion criteria were: 1) randomized controlled intervention studies; 2) population with a physical health condition; 3) NBIs vs. different intervention or no intervention; and 4) measuring physical health outcomes and/or biomarkers. Twenty-six studies were included in the review, 15 of which contributed to the meta-analysis. Compared to control groups, NBIs groups showed significant improvements in: diastolic blood pressure (MD -3.73 mmHg [-7.46 to -0.00], I = 62%) and heart rate (MD -7.44 bpm [-14.81 to -0.06], I = 0%) for cardiovascular conditions, fatigue (SMD -0.50 [-0.82 to -0.18], I = 16%) for central nervous system conditions, and body fat percentage (MD -3.61% [-5.05 to -2.17], I = 0%) for endocrine conditions. High effect heterogeneity was found in several analyses and the included studies had moderate-to-high risk of bias (RoB). The non-significant outcomes showed a direction of effect in favour of NBI groups for cardiovascular, central nervous system, endocrine, musculoskeletal, and respiratory conditions. This review found some beneficial effects in favour of NBIs for health outcomes in at least three condition groups though RoB and inconsistent effects limited some interpretations. NBIs are promising therapies that healthcare professionals can consider integrating into clinical practice.

Meta-Analysis
BACKGROUND
Diabetes nephropathy (DN), as one of the common complications of diabetes, is characterized by persistent albuminuria, decreased glomerular filtration rate, and elevated arterial blood pressure. At present, Xuebijing injection is widely used in the treatment of DN. However, few systematic reviews and meta-analysis related to Xuebijing injection intervention in DN were published. In order to more systematically and objectively evaluate the clinical efficacy of Xuebijing injection intervention in DN, we conducted systematic reviews and meta-analysis to verify it.
OBJECTIVE
The purpose of the research was to systematically evaluate the clinical efficacy of Xuebijing injection combined with alprostadil in the treatment of diabetic nephropathy.
METHODS
We searched the China National Knowledge Infrastructure (CNKI), China Biomedical Database (SinoMed), Weipu Database (VIP), Wanfang Database, PubMed, The Cochrane Library, Embase, Web of Science and other databases by computer, and searched the randomized controlled trials of Xuebijing injection combined with alprostadil in the treatment of DN at home and abroad from the establishment of the database to 2022. The main outcome indicators included blood glucose, and the secondary outcome indicators included blood lipid, renal function, urinary protein, and safety. Two evaluators independently screened the literature, extracted the data and evaluated the risk of bias in the included studies. RevMan 5.3 software was used to analyze the data.
RESULTS
A total of 14 randomized controlled trials were included, including 1233 cases, 618 cases in the treatment group and 615 cases in the control group. The results of meta-analysis demonstrated that compared with the control group, the treatment group could effectively reduce fasting plasma glucose [mean difference [MD] = -1.90, 95% CI (-2.40, -1.40), P < .00001], glycosylated hemoglobin A1c [MD = -2.38, 95% CI (-2.51, -2.25), P < .00001], 2h postprandial blood glucose [MD = -2.92, 95% CI (-3.95, -1.89), P < .00001], triacylglycerol [MD = -1.08, 95% CI (-1.66, -0.50), P = .0003], total cholesterol [MD = -1.17, 95% CI (-1.39, -0.95), P < .00001], low-density lipoprotein cholesterol [MD = -1.19, 95% CI (-1.60, -0.78), P < .00001], high-density lipoprotein cholesterol [MD = 0.32, 95% CI (0.23, 0.42), P < .00001], serum creatinine [MD = -42.95, 95% CI (-57.46, -28.43), P < .00001], blood urea nitrogen [MD = -2.24, 95%CI (-2.62,-1.86), P < .00001], blood β2 microglobulin [SMD = -1.49, 95% CI (-1.70, -1.28), P < .00001], urine β2 microglobulin [SMD = -0.81, 95% CI (-1.04, -0.58), P < .00001], 24-hour urinary protein quantification [MD = -0.20, 95% CI (-0.26, -0.14), P < .00001], urinary albumin excretion rate [SMD = -1.15, 95% CI (-1.38, -0.93), P < .00001].
CONCLUSION
Xuebijing injection combined with alprostadil has more advantages in treating DN compared to routine Western medicine.

BACKGROUND AND OBJECTIVE
This scientific review involves a sequential analysis of randomized trial research focused on the incidence of shivering in patients undergoing cardiac surgery. The study conducted a comprehensive search of different databases, up to the end of 2020. Only randomized trials comparing magnesium administration with either placebo or no treatment in patients expected to experience shivering were included. The primary objective was to evaluate shivering occurrence, distinguishing between patients receiving general anesthesia and those not. Secondary outcomes included serum magnesium concentrations, intubation time, post-anesthesia care unit stay, hospitalization duration, and side effects. Data collection included patient demographics and various factors related to magnesium administration.
MATERIAL AND METHODS
This scientific review analyzed 64 clinical trials meeting inclusion criteria, encompassing a total of 4303 patients. Magnesium was administered via different routes, primarily intravenous, epidural, and intraperitoneal, and compared against placebo or control. Data included demographics, magnesium dosage, administration method, and outcomes. Heterogeneity was assessed using the I statistic. Some studies were excluded due to unavailability of data or non-responsiveness from authors.
RESULT
and discussion: Out of 2546 initially identified articles, 64 trials were selected for analysis. IV magnesium effectively reduced shivering, with epidural and intraperitoneal routes showing even greater efficacy. IV magnesium demonstrated cost-effectiveness and a favorable safety profile, not increasing adverse effects. The exact dose-response relationship of magnesium remains unclear. The results also indicated no significant impact on sedation, extubation time, or gastrointestinal distress. However, further research is needed to determine the optimal magnesium dose and to explore its potential effects on blood pressure and heart rate, particularly regarding pruritus prevention.
CONCLUSION
This study highlights the efficacy of intravenous (IV) magnesium in preventing shivering after cardiac surgery. Both epidural and intraperitoneal routes have shown promising results. The safety profile of magnesium administration appears favorable, as it reduces the incidence of shivering without significantly increasing costs. However, further investigation is required to establish the ideal magnesium dosage and explore its potential effects on blood pressure, heart rate, and pruritus prevention, especially in various patient groups.

Meta-Analysis
Effectiveness of pedometer-based walking programmes in improving some modifiable risk factors of stroke among community-dwelling older adults: a systematic review, theoretical synthesis and meta-analysis.
BACKGROUND
Pedometer-based walking programs hold promise as a health promotion strategy for stroke prevention in community-dwelling older adults, particularly when targeted at physical activity-related modifiable risk factors. The question arises: What is the effectiveness of pedometer-based walking program interventions in improving modifiable stroke risk factors among community-dwelling older adults?
METHOD
Eight databases were searched up to December 2, 2023, following the Preferred Reporting Items for Systematic Review and Meta-Analysis protocol. Inclusion criteria focused on randomized controlled trials (RCTS) involving community-dwelling older adults and reported in English. Two independent reviewers utilized Physiotherapy Evidence Database (PEDro) tool to extract data, assess eligibility, evaluate study quality, and identify potential bias. Standardized mean difference (SMD) was employed as summary statistics for primary -physical activity level -and secondary outcomes related to cardiovascular function (blood pressure) and metabolic syndrome, including obesity (measured by body mass index and waist circumference), fasting blood sugar, glycated hemoglobin, high-density lipoprotein cholesterol (HDL-C), and triglycerides. A random-effects model was used to generate summary estimates of effects.
RESULTS
The review analyzed eight studies involving 1546 participants aged 60-85 years, with 1348 successfully completing the studies. Across these studies, pedometer-based walking programs were implemented 2-3 times per week, with sessions lasting 40-60 minutes, over a duration of 4-26 weeks. The risk of bias varied from high to moderate. Our narrative synthesis revealed positive trends in HDL-C levels, fasting blood sugar, and glycated hemoglobin, suggesting improved glycemic control and long-term blood sugar management. However, the impact on triglycerides was only marginal. Primary meta-analysis demonstrated significantly improved physical activity behavior (SMD=0.44,95%CI:0.26, 0.61,p=<0.00001;I=0%;4 studies; 532 participants) and systolic blood pressure (SMD=-0.34,95%CI:-0.59,-0.09;p=<0.008;I=65%,2 studies;249 participants), unlike diastolic blood pressure (SMD=0.13,95%CI:-0.13,-0.38,p=0.33; I=91%; 2 studies; 237 participants). Interventions based on social cognitive, self-efficacy, and self-efficiency theory(ies), and social cognitive theory applied in an ecological framework, were linked to successful physical activity behavior outcomes.
CONCLUSION
Pedometer-based walking programs, utilizing interpersonal health behavior theory/ecological framework, enhance physical activity behavior and have antihypertensive effects in community-dwelling older adults. While they do not significantly affect diastolic blood pressure, these programs potentially serve as a primary stroke prevention strategy aligning with global health goals.
