Abstract
CONTEXT Rheumatoid arthritis is a chronic inflammatory disease that causes synovitis. Vitamin D deficiency is common in rheumatoid arthritis. OBJECTIVE This systematic review and meta-analysis investigated whether vitamin D supplementation affects the inflammatory and clinical outcomes in patients with rheumatoid arthritis on the basis of randomized clinical trials. DATA SOURCES A literature search was performed in the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, MEDLINE, Embase, and Google Scholar for articles published until May 2022. DATA EXTRACTION The studies were selected according to PRISMA guidelines, and the risk of bias was assessed for randomized controlled trials. DATA ANALYSIS A random effects model was used to conduct a meta-analysis, and heterogeneity was assessed using the I2 statistic. Of 464 records, 11 studies were included from 3049 patients. Conclusion: Vitamin D supplementation did not significantly reduce C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), disease activity score in 28 joints (DAS28), or the health assessment questionnaire score; however, the response to supplementation was highly heterogeneous. The pooled analysis showed that vitamin D significantly reduced the pain-visual analogue scale (VAS) weighted mean difference (WMD = -1.30, 95% confidence interval [CI] [-2.34, -27], P = .01), DAS28-CRP (WMD = -.58, 95% CI [-.86, -.31], P < .0001), and DAS28-ESR (WMD = -.58, 95% CI [-.86, -.31], P = .0001). Subgroup analysis for vitamin D doses (>100 µg per day versus <100 µg per day) showed that the higher doses had a more significant effect on CRP than the lower doses (P < .05). CONCLUSIONS There was no significant difference between the effect of 2 vitamin D doses on ESR and DAS28. To minimize the high heterogeneity among studies in this meta-analysis, other confounding factors such as baseline vitamin D, age, dietary vitamin D, time of year, sun exposure, drug interaction, effect dosage, and power of study should be examined.

Abstract
OBJECTIVE To evaluate the impact of a multi-level, multi-component (MLMC) adult obesity intervention on beverage intake in Native American adults living in five geographically and culturally diverse tribal communities. DESIGN A 14-month, community-randomised, MLMC design was utilised, with three communities randomised to Intervention and two communities randomised to Comparison. FFQ were administered pre- and post-interventions, and difference-in-differences (DiD) analysis was used to assess intervention impact on beverage intake. SETTING The intervention took place within food stores, worksites, schools and selected media outlets located in the five communities. Key activities included working with store owners to stock healthy beverages, display and dispersal of educational materials, support of policies that discouraged unhealthy beverage consumption at worksites and schools and taste tests. PARTICIPANTS Data were collected from 422 respondents between the ages of 18 and 75 living in the five communities pre-intervention; of those, 299 completed post-intervention surveys. Only respondents completing both pre- and post-intervention surveys were included in the current analysis. RESULTS The DiD for daily servings of regular, sugar-sweetened soda from pre- to post-intervention was significant, indicating a significant decrease in Intervention communities (P < 0·05). No other changes to beverage intake were observed. CONCLUSIONS Large, MLMC obesity interventions can successfully reduce the intake of regular, sugar-sweetened soda in Native American adults. This is important within modern food environments where sugar-sweetened beverages are a primary source of added sugars in Native American diets.

Abstract
OBJECTIVE The development of obesity and chronic diseases in adulthood often results from a childhood pattern of dietary excesses. This study aimed to identify dietary inadequacies and excesses of multiethnic youth in Edmonton. METHODS A cross-sectional survey of a convenience sample of 473 multiethnic youth between 11 and 18 years was conducted in 12 schools in Edmonton between October 2013 and March 2014. Data were analyzed to determine for each participant mean daily energy and nutrient intakes, dietary adequacy, and nutrient densities. Participants were divided by self-identified ethnicity (Indigenous, European, African and Middle Eastern, and Asian). RESULTS For all nutrients examined, the mean percentage of calories from fat was higher among European (31.7%) and Indigenous youth (31.8%) compared to African and Middle Eastern (28.3%) and Asian youth (29.0%), while Asian youth had the highest percentage of calories from protein (17.7%) compared to other ethnic groups (Indigenous = 15.5%; African & Middle Eastern = 16.5%; European = 16.2%). The majority of youth fell below the recommended values for dietary fiber (83.3-92.0%), vitamins D (84.4-90.2%), and E (89.5-92.0%). More than 50% fell below the dietary reference intakes (DRIs) for vitamin A, vitamin B5, calcium, and magnesium; >30% were below the DRI for folate, zinc, and vitamins B6, and C. The diet of girls contained a greater density of fiber compared to boys (9.3 vs. 8.0 g/1000 kcal; p-value = 0.002). CONCLUSIONS Inadequate dietary intake is evident among the majority of multiethnic youth in Edmonton. There is a need to develop strategies to reduce the burden of poor nutrition status for youth.

Abstract
BACKGROUND Since December 2019, coronavirus disease 2019 (COVID-19) has become a major health problem that is spreading all over the world. Several viral infections such as SARS, MERS, and influenza have been associated with adverse pregnancy outcomes. The question arises whether pregnant women are at greater risk of complications related to COVID-19 compared to other people What complications should we expect in the fetuses whose mothers were infected? AIMS This review aims to provide a summary of studies on symptoms of COVID-19 and the possible risks of COVID-19 among pregnant women, as well as complications in fetuses and neonates whose mothers were infected with COVID-19. METHODS The included data were provided from Web of Science, Cochrane, PubMed, and Scopus which are extracted from the published studies in English until April 2nd, 2020 that contained data on the risk of COVID-19 in pregnancy. RESULTS The early symptoms of patients with COVID-19 were fever, cough, dyspnea, myalgia, and fatigue; while production of sputum, headache, hemoptysis, and diarrhea were other symptoms which were less common. There is no evidence of vertical maternal-fetal transmission in pregnant women with COVID-19. CONCLUSIONS The clinical findings in pregnant women with COVID-19 are not significantly different compared to other patients, and pregnant women with COVID-19 are not at a higher risk of developing critical pneumonia compared to non-pregnant women. Although, there has been no sign of vertical infection in infants, but maternal infection can cause serious problems such as preterm labour and fetal distress.

Abstract
INTRODUCTION The aim of this systematic review and meta-analysis was to summarize all the existing randomized controlled trials (RCTs) evidence and to evaluate the effects of green cardamom on lipoproteins, glycemic control and anthropometric parameters in healthy and/or with disease types compared with the control. METHOD Two independent authors systematically searched online databases including EMBASE, Scopus, PubMed, Cochrane Library, and Web of Science from inception until 30th July 2019. RCTs complying with the following criteria were included in this meta-analysis: human trials with either cross-over design or parallel design, trials with data on the effects of green cardamom on serum lipoproteins and glycemic control and anthropometric parameters with standard deviation and related 95% confidence interval for the both intervention and placebo groups. The heterogeneity among the included studies was assessed using Cochrane's Q test and I-square (I2) statistic. Data were pooled using a random-effects model and weighted mean difference (WMD) was considered as the overall effect size. RESULT Seven trials were included in this meta-analysis. Triglycerides were significantly reduced after cardamom supplementation when compared with the control group. Cardamom intake from 3 small studies resulted in a significant increase in BMI when compared with the control group. However, cardamom supplementation did not have any significant effect on total cholesterol, LDL-cholesterol, HDL-cholesterol, fasting plasma glucose and body weight when compared with the control group. CONCLUSION This meta-analysis demonstrated that green cardamom intake significantly reduced triglycerides levels which may have played an indirect role in improved clinical symptoms in diseases with metabolic disorders.

Abstract
INTRODUCTION This study examined the prevalence of pre-hypertension (PHT) and hypertension (HT) in urban youth, and assessed the effects of sodium intake and obesity on blood pressure (BP) by ethnicity. METHODS A convenience sample of 557 multiethnic youth, aged 11-23 years, was recruited from 12 schools and institutions in Edmonton, Alberta, Canada. Participants were divided by self-identified ethnicity into four groups (Indigenous, African and Middle Eastern (AME), Asian, and European). RESULTS Between October 2013 and March 2014, one-on-one interviews were conducted to collect data on demographics, physical activity, diet, and Body Mass Index (BMI). BP was obtained at two different times during the interview and measured a third time in cases of high variability. The standard deviation scores (SDS) of systolic BP (SBP) and diastolic BP (DBP) were used to estimate associations with sodium intake (per 1000 mg/day). Overall, 18.2% and 5.4% of the participants had PHT and HT, respectively. Indigenous and AME participants showed the highest rates of PHT (23.1%). Indigenous and European participants showed higher rates of HT (8.3% and 5.3%, respectively) than other ethnic groups (AME = 4.4%, Asian = 3.9%). There was a positive association between 1000 mg/day increase in sodium intake and SDS of SBP by 0.041 (95% CI 0.007-0.083; p = 0.04) among pre-hypertensive participants. Over 85% of participants exceeded the recommended dietary sodium intake. Mean BMI and dietary sodium intake were higher among pre-hypertensive participants (4219 mg/day) than normotensive (3475 mg/day). CONCLUSIONS The prevalence of HT varied by ethnicity. High dietary sodium intake was of concern. There is a need for culturally-tailored, population-based interventions to reduce sodium intake.

Abstract
BACKGROUND This systematic review and meta-analysis of randomized controlled trials (RCTs) were performed to determine the effect of quercetin administration on blood pressures and endothelial function among patients with metabolic syndrome (MetS) and related disorders. METHODS We searched systematically online databases including Cochrane Library, EMBASE, MEDLINE, and Web of Science to identify the relevant RCTs until December 2018. Q-test and I2 statistics were applied to assess heterogeneity among the included studies. Data were pooled using a random-effects model and weighted mean difference (WMD) was considered as the overall effect size. RESULTS Out of 284 citations, 8 RCTs were included in the meta-analysis. We found a significant reduction in systolic blood pressure (SBP) (WMD: -1.69; 95% CI: -3.22, -0.17) following the intake of quercetin supplements. However, quercetin supplementation did not significantly affect diastolic blood pressure (DBP) (WMD: -3.14; 95% CI: -8.24, 1.95), vascular cell adhesion molecule 1 (VCAM-1) (WMD: -24.49; 95% CI: -53.74, 4.77) and intercellular adhesion molecule 1 (ICAM-1) (WMD: -5.78; 95% CI: -12.93, 1.38). CONCLUSION In summary, the current meta-analysis demonstrated that quercetin supplementation significantly reduced SBP, yet did not affect DBP, VCAM-1 and ICAM-1 among patients with MetS and related disorders.

Abstract
Background There are current trials investigating the effect of resveratrol supplementation on lipid profiles and liver enzymes among patients with metabolic syndrome (MetS) and related disorders; however, their findings are controversial. This systematic review and meta-analysis were aimed to determine the effects of resveratrol supplementation on lipid profiles and liver enzymes among patients with MetS and related disorders. Methods We performed a comprehensive search of the following online databases up to November 2018: Cochrane Library, PubMed, Embase, and Web of Science. The relevant articles were assessed for quality of studies using the Cochrane risk of bias tool. Results Out of 2459 citations, 31 articles were appropriate for including to the current meta-analysis. The pooled results indicated that resveratrol use significantly decreased total cholesterol [weighted mean difference (WMD) = − 7.65 mg/dL; 95% CI, − 12.93, − 2.37; P < 0.01; I2: 83.4%] and increased gamma-glutamyl transferase (GGT) concentrations (WMD = 1.76 U/l; 95% CI, 0.58, 2.94; P < 0.01; I2: 20.1%). We found no significant effect of resveratrol supplementation on triglycerides (WMD = − 5.84 mg/dL; 95% CI, − 12.68, 1.00; P = 0.09; I2: 66.8%), LDL- (WMD = -2.90 mg/dL; 95% CI, − 10.88, 5.09; P = 0.47; I2: 96.0%), HDL-cholesterol (WMD = 0.49 mg/dL; 95% CI, − 0.80, 1.78; P = 0.45; I2: 74.0%), alanine aminotransferase (ALT) (WMD = -0.14 U/l; 95% CI, − 3.69, 3.41; P = 0.93; I2: 79.6%), and aspartate aminotransferase (AST) (WMD = -0.34 U/l; 95% CI, − 2.94, 2.27; P = 0.80; I2: 88.0%) concentrations. Conclusions This meta-analysis demonstrated that resveratrol supplementation among patients with MetS and related disorders significantly reduced total cholesterol and increased GGT concentrations, but did not affect triglycerides, LDL-, HDL-cholesterol, ALT, and AST concentrations. This data suggests that resveratrol may have a potential cardio-protective effect in patients with MetS and related disorders.

Abstract
Intake of heterocyclic amines (HCAs) and other mutagenic compounds formed during cooking has been hypothesized to be responsible for the positive association observed between red meat and colorectal cancer. We evaluated whether well-done/very well-done preferences for various meat and fish items, higher intakes of meat and fish, and meat-derived and fish-derived HCA are associated with the risk of colorectal adenoma (CRA) in a Japanese-Brazilian population. We selected 302 patients with adenoma and 403 control individuals who underwent total colonoscopy between 2007 and 2013, and collected information on aspects of meat intake using a detailed questionnaire. We also estimated HCA intake of the study participants using an HCA database that matched the cooking methods of this population. Latent class analysis on the basis of response to doneness preferences for different cooking methods of commonly consumed meat and fish items identified four distinct subgroups. Compared with the subgroup characterized by a preference for rare/medium well-done cooking for most meat and fish items, the odds ratio of CRA for the well-done/very well-done preference subgroup was 1.19 (95% confidence interval: 0.51-2.75). High intake of mixed-meat dishes was suggestively associated inversely with CRA, whereas a high intake of poultry was associated positively with CRA. No clear association with intake of total or specific HCAs and no effect modification by N-acetyltransferase 2 acetylation genotype were observed. We found no statistically significant associations between meat and HCA intake and CRA. These findings do not support a positive association between meat and meat-derived HCA intake and the risk of CRA.

Abstract
OBJECTIVES This paper explores patient experiences and identifies barriers and opportunities for improving access to healthcare for patients from the Canadian north who travel to receive medical care in a Southern province. DESIGN A mixed-methods, cross-sectional study involved one-on-one interviews, focus group discussions and key informant interviews. PARTICIPANTS 52 one-on-one interviews with Northwest Territories (NWT) patients and patient escorts and two focus group discussions (n=10). Fourteen key informant interviews were conducted with health workers, programme managers and staff of community organisations providing services for out-of-province patients. A Community Advisory Board guided the development of the questionnaires and interpretation of results. RESULTS Respondents were satisfied with the care received overall, but described unnecessary burdens and bureaucratic challenges throughout the travel process. Themes relating to access to healthcare included: plans and logistics for travel; level of communication between services; clarity around jurisdiction and responsibility for care; indirect costs of travel and direct costs of uninsured services; and having a patient escort or advocate available to assist with appointments and navigate the system. Three themes related to healthcare experiences included: cultural awareness, respect and caring, and medical translation. Respondents provided suggestions to improve access to care. CONCLUSIONS Patients from NWT need more information and support before and during travel. Ensuring that medical travellers and escorts are prepared before departing, that healthcare providers engage in culturally appropriate communication and connecting travellers to support services on arrival have the potential to improve medical travel experiences.

Abstract
Background:
The findings of trials investigating the effects of L-carnitine administration on serum
lipids are inconsistent. This meta-analysis of randomized controlled trials (RCTs) was performed to summarize
the effects of L-carnitine intake on serum lipids in patients and healthy individuals.
Methods:
Two authors independently searched electronic databases including MEDLINE, EMBASE, Cochrane
Library, Web of Science, PubMed and Google Scholar from 1990 until August 1, 2019, in order to find relevant
RCTs. The quality of selected RCTs was evaluated using the Cochrane Collaboration risk of bias tool. Cochrane’s
Q test and I-square (I2) statistic were used to determine the heterogeneity across included trials. Weight mean
difference (SMD) and 95% CI between the two intervention groups were used to determine pooled effect sizes.
Subgroup analyses were performed to evaluate the source of heterogeneity based on suspected variables such as,
participant’s health conditions, age, dosage of L-carnitine, duration of study, sample size, and study location
between primary RCTs.
Results:
Out of 3460 potential papers selected based on keywords search, 67 studies met the inclusion criteria and
were eligible for the meta-analysis. The pooled results indicated that L-carnitine administration led to a significant
decrease in triglycerides (WMD: -10.35; 95% CI: -16.43, -4.27), total cholesterol (WMD: -9.47; 95% CI: -
13.23, -5.70) and LDL-cholesterol (LDL-C) concentrations (WMD: -6.25; 95% CI: -9.30, -3.21), and a significant
increase in HDL-cholesterol (HDL-C) levels (WMD: 1.39; 95% CI: 0.21, 2.57). L-carnitine supplementation did
not influence VLDL-cholesterol concentrations. When we stratified studies for the predefined factors such as
dosage, and age, no significant effects of the intervention on triglycerides, LDL-C, and HDL-C levels were found.
Conclusion:
This meta-analysis demonstrated that L-carnitine administration significantly reduced triglycerides,
total cholesterol and LDL-cholesterol levels, and significantly increased HDL-cholesterol levels in the pooled
analyses, but did not affect VLDL-cholesterol levels; however, these findings were not confirmed in our subgroup
analyses by participant’s health conditions, age, dosage of L-carnitine, duration of study, sample size, and study
location.

Abstract
The aim of this systematic review and meta-analysis was to evaluate the effects of resistant starch (RS) on glycemic status, serum lipoproteins and inflammatory markers in patients with metabolic syndrome (MetS) and related disorders. Two independent authors systematically searched online database including EMBASE, Scopus, PubMed, Cochrane Library, and Web of Science from inception until 30 April 2019. Cochrane Collaboration risk of bias tool was applied to assess the methodological quality of included trials. The heterogeneity among the included studies was assessed using Cochrane's Q test and I-square (I2) statistic. Data were pooled using a random-effects model and weighted mean difference (WMD) was considered as the overall effect size. Nineteen trials were included in this meta-analysis. Administration of RS resulted in significant reduction in fasting plasma glucose (FPG) (14 studies) (WMD: -4.28; 95% CI: -7.01, -1.55), insulin (12 studies) (WMD: -1.95; 95% CI: -3.22, -0.68), and HbA1C (8 studies) (WMD: -0.60; 95% CI: -0.95, -0.24). When pooling data from 13 studies, a significant reduction in total cholesterol levels (WMD: -8.19; 95% CI: -15.38, -1.00) and LDL-cholesterol (WMD: -8.57; 95% CI: -13.48, -3.66) were found as well. Finally, RS administration was associated with a significant decrease in tumor necrosis factor alpha (TNF-α) (WMD: -2.02; 95% CI: -3.14, -0.90). This meta-analysis showed beneficial effects of RS on improving FPG, insulin, HbA1c, total cholesterol, LDL-cholesterol and TNF-α levels in patients with MetS and related disorders, but it did not affect HOMA-IR, triglycerides, HDL-cholesterol, CRP and IL-6 levels.

Abstract
BACKGROUND In the current meta-analysis of randomized controlled trials (RCTs), the effects of vitamin D supplementation on mental health, and biomarkers of inflammation and oxidative stress in patients with psychiatric disorders are assessed. METHODS The following databases were search up to March 2019: MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials. The quality of the relevant extracted data was assessed according to the Cochrane risk of bias tool. Data were pooled by the use of the inverse variance method and expressed as mean difference with 95% Confidence Intervals (95% CI). RESULTS Eleven effect sizes from nine studies were included in the final analyses. A pooled analysis of 9 effect sizes showed a significant reduction in Beck Depression Inventory (BDI) score following supplementation with vitamin D [weighted mean difference (WMD): -3.91; 95% CI: -5.15 -2.66), I2= 85.9%]. Combining data from two available studies on the effects of vitamin D supplementation on Pittsburgh Sleep Quality Index (PSQI) also revealed a significant reduction in this score following the intervention (WMD: -1.78; 95% CI: -2.28, -1.28). In addition, there were significant increase in glutathione (GSH) through 3 studies (WMD: 180.70; 95% CI: 6.76, 354.64), and in total antioxidant capacity (TAC) through 3 studies (WMD: 90.09; 95% CI: 56.36, 123.82) after vitamin D supplementation. Combining data from five studies, we found a significant reduction in C-reactive protein (CRP) concentrations after vitamin D supplementation (WMD: -1.74; 95% CI: -2.82, -0.66). CONCLUSIONS Overall, the current meta-analysis demonstrated that taking vitamin D supplements among patients with psychiatric disorders had beneficial effects on BDI, PSQI, GSH, TAC and CRP levels, but did not affect other biomarkers of inflammation and oxidative stress.

Abstract
The findings of trials investigating the effect of L-carnitine administration on glycemic control are controversial. This meta-analysis of randomized controlled trials (RCTs) was performed to explore the effects of L-carnitine intake on glycemic control. Two authors independently searched electronic databases including MEDLINE, EMBASE, Cochrane Library, Web of Science, PubMed and Google scholar from 1990 until February 2019, in order to find relevant RCTs. 37 studies with 44 effect sizes met the inclusion criteria and were eligible for the meta-analysis. L-carnitine supplementation resulted in a significant reduction in fasting plasma glucose (FPG) (WMD: -4.57; 95 % CI: -6.88, -2.25), insulin (WMD: -1.21; 95 % CI: -1.85, -0.57), homeostatic model assessment for insulin resistance (HOMA-IR) (WMD: -0.67; 95 % CI: -0.90, -0.44) and HbA1C concentrations (WMD: -0.30; 95 % CI: -0.47, -0.13). L-Carnitine supplementation significantly reduced FPG, insulin, HOMA-IR, and HbA1c levels.

Abstract
Impaired endothelial function is an important risk factor for cardiovascular disease (CVD). Curcumin supplementation might be an appropriate approach to decrease the complications of CVD. Randomized controlled trials assessing the effects of curcumin supplementation on endothelial function were included. Two independent authors systematically searched online database including EMBASE, Scopus, PubMed, Cochrane Library, and Web of Science with no time restriction. Cochrane Collaboration risk of bias tool was applied to assess the methodological quality of included trials. Between-study heterogeneities were estimated using the Cochran's Q test and I-square (I2 ) statistic. Data were pooled using a random-effects model, and weighted mean differences (WMDs) were considered as the overall effect sizes. Ten studies with 11 effect sizes were included. We found a significant increase in flow-mediated dilation (FMD) following curcumin supplementation (WMD: 1.49; 95% CI [0.16, 2.82]). There was no effect of curcumin supplement on pulse wave velocity (PWV; WMD: -41.59; 95% CI [-86.59, 3.42]), augmentation index (Aix; WMD: 0.71; 95% CI [-1.37, 2.79]), endothelin-1 (ET-1; WMD: -0.30; 95% CI [-0.96, 0.37]), and soluble intercellular adhesion molecule-1 (sICAM-1; WMD: -10.11; 95% CI [-33.67, 13.46]). This meta-analysis demonstrated the beneficial effects of curcumin supplementation on improving FMD, though it did not influence PWV, Aix, Et-1, and sICAM-1.

Abstract
Background and objective Stroke is a devastating condition with long-term comorbidities including metabolic abnormalities. Alpha lipoic acid (ALA), with its antioxidant properties, might improve metabolic status of patients, though current evidence is still inclusive. This systematic review of randomized controlled trials (RCTs) was conducted to summarize the existing evidence regarding the effects of ALA supplementation on fasting glucose and lipid profiles among patients with stroke. Methods We searched Cochrane Library, EMBASE, MEDLINE, and Web of Science from 1990 until April 5th, 2018. The relevant randomized-controlled articles, based on defined key words, were included in the analyses. Two independent researchers investigated study eligibility, extracted data, and assessed the risk of bias for included studies. Heterogeneity among included studies was tested using Q-test and I2 statistics. Random-effects models were applied to pool the data and standardized mean differences (WMD) were considered as summary effect size. Results A total of five studies (140 patients in each intervention group) were included in our meta-analysis. The findings showed that ALA supplementation significantly decreased fasting glucose levels (WMD -36.93 mg/dL; 95% CI, -65.58, -8.28; P = 0.01; I2 = 85.0%) in patients with stroke. We found no significant effect of ALA supplementation on triglycerides (WMD -7.45 mg/dL; 95% CI, -51.35, 36.45; P = 0.739; I2 = 83.9%), total cholesterol (WMD -23.23 mg/dL; 95% CI, -48.07, 1.62; P = 0.067; I2 = 80.5%), LDL-cholesterol (WMD -10.46 mg/dL; 95% CI, -21.01, 0.09; P = 0.052; I2 = 47.4%) and HDL-cholesterol levels (WMD -3.02 mg/dL; 95% CI, -20.18, 14.14; P = 0.730; I2 = 85.8%). Conclusions This meta-analysis suggested the beneficial impacts of ALA supplementation in improving fasting glucose of patients diagnosed with stroke.

Abstract
The aim of this systematic review and meta-analysis was to evaluate the effects of spirulina on glycemic control and serum lipoproteins in patients with metabolic syndrome (MetS) and related disorders. Two independent authors systematically searched online database including EMBASE, Scopus, PubMed, Cochrane Library, and Web of Science from inception until April 30, 2019. The Cochrane Collaboration's risk of bias tool was applied to assess the methodological quality of included trials. The heterogeneity among the included studies was assessed using Cochrane's Q test and I-square (I2 ) statistic. Pooling effect sizes from studies showed a significant reduction in fasting plasma glucose (FPG; weighted mean difference [WMD]: -10.31; 95% confidence interval, CI [-16.21, -4.42]) and insulin concentrations (WMD: -0.53; 95% CI [-0.62, -0.44]) following the administration of spirulina. Pooled analysis showed also a significant reduction in total cholesterol (WMD: -20.50; 95% CI [-38.25, -2.74]), low-density lipoprotein cholesterol (LDL-C; WMD: -19.02; 95% CI [-36.27, -1.78]), and very low-density lipoprotein cholesterol (VLDL-C) concentrations (WMD: -6.72; 95% CI [-9.19, -4.26]) and a significant increase in high-density lipoprotein cholesterol (HDL-C) levels (WMD: 1.42; 95% CI [0.16, 2.68]) following spirulina therapy. This meta-analysis demonstrated the beneficial effects of spirulina supplementation on improving FPG, insulin, total cholesterol, LDL-C, VLDL-C, and HDL-C levels in patients with MetS and related disorders.

Abstract
INTRODUCTION There are current trials investigating the effect of resveratrol supplementation on endothelial function and blood pressures among patients with metabolic syndrome (MetS); however, the findings are controversial. AIM This systematic review and meta-analysis of randomized controlled trials (RCTs) were carried out to summarize the effects of resveratrol supplementation on endothelial activation and blood pressures among patients with MetS and related disorders. METHODS We searched systematically online databases including: PubMed-Medline, Embase, ISI Web of Science and Cochrane Central Register of Controlled Trials until October, 2018. Two independent authors extracted data and assessed the quality of included articles. Data were pooled using the fixed- or random-effects model and considered as standardized mean difference (SMD) with 95% confidence intervals (95% CI). RESULTS Out of 831 electronic citations, 28 RCTs (with 33 findings reported) were included in the meta-analyses. The findings showed that resveratrol intervention significantly increased flow-mediated dilatation (FMD) levels (SMD 1.77; 95% CI 0.25, 3.29; P = 0.02; I2: 96.5). However, resveratrol supplements did not affect systolic blood pressure (SBP) (SMD - 0.27; 95% CI - 0.57, 0.03; P = 0.07; I2: 88.9) and diastolic blood pressure (DBP) (SMD - 0.21; 95% CI - 0.52, 0.11; P = 0.19; I2: 89.8). CONCLUSIONS Resveratrol supplementation significantly increased FMD among patients with MetS and related disorders, but did not affect SBP and DBP. Additional prospective studies are needed to investigate the effect of resveratrol supplementation on endothelial function and blood pressures, using higher-dose of resveratrol with longer durations.

Abstract
Rationale: Higher indoor particulate matter (PM) concentrations are linked with increased asthma morbidity. Dietary intake of fatty acids, also linked with asthma outcomes, may influence this relationship. Objectives: To determine the relationship between omega-3 and omega-6 fatty acid intake and pediatric asthma morbidity, and the association between fatty acid intake and strength of indoor, PM-related asthma symptoms, albuterol use, and systemic inflammation. Methods: Analyses included 135 children with asthma enrolled in the AsthmaDIET Study. At baseline, 3 months, and 6 months, data included: week-long average home indoor concentration of PM ≤2.5 μm in aerodynamic diameter and PM ≤10 μm in aerodynamic diameter, dietary intake of omega-3 and omega-6 fatty acids, daily symptoms, and peripheral blood leukocytes. Asthma severity and lung function were assessed at baseline. Multivariable regression models, adjusted for known confounders, were used to determine associations between each fatty acid and outcomes of interest, with interaction terms (fatty acids × PM) in longitudinal analyses. Measurements and Main Results: Higher omega-6 intake associated with increased odds of increased asthma severity (P = 0.02), and lower FEV1/FVC ratio (P = 0.01). Higher omega-3 intake associated with reduced effect of indoor PM ≤2.5 μm in aerodynamic diameter on symptoms (P < 0.01), whereas higher omega-6 intake associated with amplified effect of indoor PM ≤2.5 μm in aerodynamic diameter on symptoms and circulating neutrophil percentage (P < 0.01). Conclusions: Omega-3 and omega-6 intake are associated with pediatric asthma morbidity and may modify the asthmatic response to indoor PM.

Abstract
The purpose of this systematic review and meta-analysis of randomized controlled trials (RCTs) is to determine the effectiveness of probiotic supplementation on clinical symptoms, weight loss, glycemic control, lipid and hormonal profiles, and biomarkers of inflammation and oxidative stress in women with polycystic ovary syndrome (PCOS). Eligible studies were systematically searched from Cochrane Library, Embase, Medline, and Web of Science databases until January 2019. Cochran (Q) and I-square statistics were used to measure heterogeneity among included studies. Data were pooled by using random-effect model and expressed as standardized mean difference (SMD) with 95% confidence interval (CI). Eleven articles were included in this meta-analysis. Probiotic supplementation significantly decreased weight (SMD - 0.30; 95% CI, - 0.53, - 0.07; P = 0.01), body mass index (BMI) (SMD - 0.29; 95% CI, - 0.54, - 0.03; P = 0.02), fasting plasma glucose (FPG) (SMD - 0.26; 95% CI, - 0.45, - 0.07; P < 0.001), insulin (SMD - 0.52; 95% CI, - 0.81, - 0.24; P < 0.001), homeostatic model assessment for insulin resistance (HOMA-IR) (SMD - 0.53; 95% CI, - 0.79, - 0.26; P < 0.001), triglycerides (SMD - 0.69; 95% CI, - 0.99, - 0.39; P < 0.001), VLDL-cholesterol (SMD - 0.69; 95% CI, - 0.99, - 0.39; P < 0.001), C-reactive protein (CRP) (SMD - 1.26; 95% CI, - 2.14, - 0.37; P < 0.001), malondialdehyde (MDA) (SMD - 0.90; 95% CI, - 1.16, - 0.63; P < 0.001), hirsutism (SMD - 0.58; 95% CI, - 1.01, - 0.16; P < 0.001), and total testosterone levels (SMD - 0.58; 95% CI, - 0.82, - 0.34; P < 0.001), and also increased the quantitative insulin sensitivity check index (QUICKI) (SMD 0.41; 95% CI, 0.11, 0.70; P < 0.01), nitric oxide (NO) (SMD 0.33; 95% CI 0.08, 0.59; P = 0.01), total antioxidant capacity (TAC) (SMD 0.64; 95% CI, 0.38, 0.90; P < 0.001), glutathione (GSH) (SMD 0.26; 95% CI, 0.01, 0.52; P = 0.04), and sex hormone binding globulin (SHBG) levels (SMD 0.46; 95% CI, 0.08, 0.85; P = 0.01). Probiotic supplementation may result in an improvement in weight, BMI, FPG, insulin, HOMA-IR, triglycerides, VLDL-cholesterol, CRP, MDA, hirsutism, total testosterone, QUICKI, NO, TAC, GSH, and SHBG but did not affect dehydroepiandrosterone sulfate levels, and total, LDL, and HDL cholesterol levels in patients with PCOS.

Abstract
OBJECTIVE The current systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to summarize the effect of mobile health (m-health) interventions on lipid profiles among patients with metabolic syndrome and related disorders. METHODS Cochrane Library, EMBASE, PubMed, and Web of Science databases were searched to indentify the relevant randomized clinical trials published up April 30th, 2018. Two reviewers examined study eligibility, extracted data, and assessed risk of bias of included clinical trials, individually. Heterogeneity was measured using I-square (I2) statistic and Cochran's Q test. Data were pooled the standardized mean difference (SMD) effect size by the random-effect model. RESULTS 18 trials of 1681 citations were identified to be appropriate for the current meta-analysis. Findings random-effects model indicated that m-health interventions significantly decreased total- (SMD -0.54; 95% CI, -1.05, -0.03) and LDL-cholesterol levels (SMD -0.66; 95% CI, -1.18, -0.15). M-health interventions had no significant effect on triglycerides (SMD -0.14; 95% CI, -0.56, 0.28) and HDL-cholesterol levels (SMD -0.35; 95% CI, -0.81, 0.11). CONCLUSION Overall, the current meta-analysis demonstrated that m-health interventions resulted in an improvement in total- and LDL-cholesterol, but did not affect triglycerides and HDL-cholesterol levels.

Abstract
This systematic review and meta-analysis of randomized controlled trials (RCTs) was performed to evaluate the effect of probiotic and symbiotic supplementation on inflammatory markers among patients with diabetes. Clinical trials were searched using Cochrane Library, EMBASE, PubMed, and Web of Science online databases for relevant trials published until April 2018. Two independent investigators evaluated study eligibility, extracted data, and assessed risk of bias of included clinical trials. Cochran's Q test and I-square (I2) statistic were used to detect heterogeneity among the included. Data were pooled by using the random-effect model and standardized mean difference (SMD) was considered as the summary effect size. From 986 originally identified publications 18 clinical trials with a total of 1337 patients were included. Findings showed that probiotic and synbiotic supplementation among patients with diabetes significantly decreased tumor necrosis factor-α (TNF-α) (SMD = -2.99; 95% CI, -4.77, -1.20; P = 0.001; I2: 96.3), and C-reactive protein (CRP) (SMD = -0.87; 95% CI, -1.27, -0.48; P < 0.001; I2: 90.2); while significantly increased nitric oxide (NO) concentrations (SMD = 1.49; 95% CI, 0.81, 2.16; P < 0.001; I2: 92.1). There were no effects of probiotic and synbiotic supplementation on interleukin-6 (IL-6) levels (SMD = -0.65; 95% CI, -1.88, 0.59; P = 0.30; I2: 94.7). In summary, the current meta-analysis demonstrated probiotic and synbiotic supplementation among patients with diabetes significantly decreased CRP and TNF-α, and increased NO levels, but did not affect IL-6 levels.

Abstract
BACKGROUND The relationship between dietary pattern and the risk of chronic obstructive pulmonary disease (COPD) has been described; however, the exclusive role of dietary factors remains controversial. Hence, we conducted this systematic meta-analysis to clarify the role of some nutrients and antioxidant vitamins in the risk of COPD. MATERIALS AND METHODS PubMed, Embase, and Scopus databases were searched for studies evaluating the associations between COPD outcome measures, symptoms, and mortality, and intake of fruits and vegetables, fiber, fish, n-3 or n-6 fatty acids, and antioxidant vitamins in adults. The random-effect model meta-analyses were used to pool the results. RESULTS Ten cohort, six case-control, and 20 cross-sectional studies were identified. The pooled relative risks (RRs) of the COPD and confidence intervals (CIs) for the highest intake group compared with the lowest intake group were 0.74 (95% CI: 0.65-0.85) for fruit, 0.65 (95% CI: 0.55-0.78) for dietary fiber, 0.71 (95% CI: 0.58-0.85) for fish, and 0.89 (95% CI: 0.76-0.99) for vitamin C. No association was observed between the risk of COPD and the intake of vegetables, n-3 fatty acids, vitamin E, and β-carotene; however, it was associated with n-6 fatty acids 1.06 (95% CI: 0.87-1.30). CONCLUSION The results suggested that a higher intake of fruits, probably dietary fiber, and fish reduce the risk of COPD.

Abstract
This systematic review and meta-analysis of randomized controlled trials was performed to determine the effect of quercetin supplementation on glycemic control among patients with metabolic syndrome and related disorders. Databases including PubMed, MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials were searched until August 30, 2018. Nine studies with 10 effect sizes out of 357 selected reports were identified eligible to be included in current meta-analysis. The pooled findings indicated that quercetin supplementation did not affect fasting plasma glucose (FPG), homeostasis model of assessment-estimated insulin resistance, and hemoglobin A1c levels. In subgroup analysis, quercetin supplementation significantly reduced FPG in studies with a duration of ≥8 weeks (weighted mean difference [WMD]: -0.94; 95% confidence interval [CI; -1.81, -0.07]) and used quercetin in dosages of ≥500 mg/day (WMD: -1.08; 95% CI [-2.08, -0.07]). In addition, subgroup analysis revealed a significant reduction in insulin concentrations following supplementation with quercetin in studies that enrolled individuals aged <45 years (WMD: -1.36; 95% CI [-1.76, -0.97]) and that used quercetin in dosages of ≥500 mg/day (WMD: -1.57; 95% CI [-1.98, -1.16]). In summary, subgroup analysis based on duration of ≥8 weeks and used quercetin in dosages of ≥500 mg/day significantly reduced FPG levels.

Abstract
Objective: To measure the validity of a quantitative food frequency questionnaire (QFFQ). Design: A cross-sectional validation study of the QFFQ against a four-day food record (4DR) using Spearman correlation, cross-classification, kappa statistics, and Bland-Altman plotting. Setting: The Gastroenterology Department of Kaiser Permanente Hawaii. Subjects: 76 healthy Japanese American men and women, aged 40-75 years. Results: Somewhat stronger average correlations were observed between the QFFQ and the 4DR for macronutrients compared to micronutrients (Spearman rho of 0.47 vs. 0.35). Moderate correlations between the two tools were observed for macronutrients (including saturated fatty acids and dietary fibre), iron, β-carotene, vitamin C, and ethanol (rho: 0.38-0.58). Overall, stronger correlations were found among men than women between the two tools (mean rho 0.41 vs. 0.26). In a cross classification analysis, for more than 75% of the observations, a complete to relative agreement between the two methods was observed for fat, α-carotene, folate, vitamin D, and ethanol. Sex difference in agreement was minimal in cross-classification (overall extreme misclassification of 9.80% for men and 12.40% for women). Bland-Altman plots showed over-estimations of dietary fibre and α-carotene intake and an under-estimation of cholesterol intake by the QFFQ at high levels of consumption. However, the QFFQ estimation for fat, dietary fibre, folate, cholesterol, α-carotene, vitamins D and C, and ethanol intake was less than 7% different compared to the 4DR. Conclusions: The QFFQ has an adequate validity for fat, folate, vitamin D, and ethanol and can correctly categorize participants for intakes of cholesterol, dietary fibre, α-carotene, and zinc.

Abstract
OBJECTIVE Systemic inflammation and oxidative stress significantly contribute in developing coronary artery disease (CAD). This systematic review and meta-analysis was aimed to determine the effects of coenzyme Q10 (CoQ10) supplementation on biomarkers of inflammation and oxidative stress among patients with CAD. METHODS The electronic databases including MEDLINE, EMBASE, Scopus, Web of Science, and Cochrane Library databases were systematically searched until Oct 2018. The quality assessment and heterogeneity of the selected randomized clinical Trials (RCTs) were examined using the Cochrane Collaboration risk of bias tool, and Q and I2 tests, respectively. Given the presence of heterogeneity, random-effects model or fixed-effect model were used to pool standardized mean differences (SMDs) as summary effect sizes. RESULTS A total of 13 clinical RCTs of 912 potential citations were found to be eligible for the current meta-analysis. The pooled findings for biomarkers of inflammation and oxidative stress demonstrated that CoQ10 supplementation significantly increased superoxide dismutase (SOD) (SMD 2.63; 95% CI, 1.17, 4.09, P < 0.001; I2 = 94.5%) and catalase (CAT) levels (SMD 1.00; 95% CI, 0.57, 1.43, P < 0.001; I2 = 24.5%), and significantly reduced malondialdehyde (MDA) (SMD - 4.29; 95% CI - 6.72, - 1.86, P = 0.001; I2 = 97.6%) and diene levels (SMD - 2.40; 95% CI - 3.11, - 1.68, P < 0.001; I2 = 72.6%). We did not observe any significant effect of CoQ10 supplementation on C-reactive protein (CRP) (SMD - 0.62; 95% CI - 1.31, 0.08, P = 0.08; I2 = 87.9%), tumor necrosis factor alpha (TNF-α) (SMD 0.22; 95% CI - 1.07, 1.51, P = 0.73; I2 = 89.7%), interleukin-6 (IL-6) (SMD - 1.63; 95% CI - 3.43, 0.17, P = 0.07; I2 = 95.2%), and glutathione peroxidase (GPx) levels (SMD 0.14; 95% CI - 0.77, 1.04, P = 0.76; I2 = 78.7%). CONCLUSIONS Overall, this meta-analysis demonstrated CoQ10 supplementation increased SOD and CAT, and decreased MDA and diene levels, but did not affect CRP, TNF-α, IL-6, and GPx levels among patients with CAD.

Abstract
Background and objective The current systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to summarize the effect of vitamin D supplementation on endothelial activation among patients with metabolic syndrome and related disorders. Methods Cochrane library, Embase, PubMed, and Web of Science database were searched to identify related RCTs published before 30th April 2018. The heterogeneity among the included studies was assessed using Cochran’s Q test and I-square (I2) statistic. Data were pooled by using the random-effect model and standardized mean difference (SMD) was considered as summary effect size. Results Fourteen clinical trials that contained a total of 1253 participants were included in the current meta-analysis. Vitamin D supplementation significantly decreased von willebrand factor (vWF) (SMD -0.27; 95% CI, − 0.46, − 0.08; P = 0.006; I2:40.5%). However, we found no significant impact of vitamin D supplementation on intercellular adhesion molecule 1(ICAM-1) (SMD -1.96; 95% CI, − 4.02, 0.09; P = 0.06; I2:97.4%), vascular celladhesion molecule 1 (VCAM-1) (SMD -0.50; 95% CI, − 1.19, 0.19; P = 0.15; I2:91.2%), on E-selectin (SMD -0.04; 95% CI, − 0.36, 0.28; P = 0.81; I2:78.8%) and endothelin (SMD -0.49; 95% CI, − 1.18, 0.19; P = 0.15; I2:90.5%). The pooled data from trials of vitamin D supplementation with dosage of ≤4000 IU/day (− 0.37, 95% CI: -0.65, − 0.10, I2: 73.5%) significantly reduced vWF concentrations, while there was no effect of vitamin D supplementation on vWF concentrations among trials with the dosage of intervention > 4000 IU/day (− 0.17, 95% CI: -0.43, 0.10, I2: 0.0%). VWF concentrations significantly reduced in pooled data from trials with duration study ≤8 weeks (− 0.37, 95% CI: -0.67, − 0.07, I2: 60.6%), but there was no effect of vitamin D supplementation on vWF concentrations among trials with > 8 weeks (− 0.20, 95% CI: -0.45, 0.05, I2: 0.0%). While there was no effect of vitamin D supplementation on vWF concentrations among trials with total sample size of ≤60 patients (− 0.03, 95% CI: -0.42, 0.36, I2: 0.0%), vWF concentrations in trials with more than 60 patients decreased significantly (− 0.34, 95% CI: -0.56, − 0.12, I2: 60.9%). Conclusions Overall, the current meta-analysis demonstrated that vitamin D supplementation to patients with metabolic syndrome and related disorders resulted in an improvement in vWF, but did not affect ICAM-1, VCAM-1, E-selectin and endothelin levels.

Abstract
This systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to summarize the effect of resveratrol intake on weight loss. We searched the following databases until July 2018: MEDLINE, EMBASE, Web of Science and Cochrane Central Register of Controlled Trials. Data were pooled using the inverse variance method and expressed as standardized mean difference (SMD) with 95% confidence intervals (95% CI). Out of 831 reports, 36 RCTs were eligible for including to our meta-analysis. The pooled results, using random-effects model showed that resveratrol supplementation significantly decreased body weight (SMD = -0.17; 95% CI, -0.33, -0.01; P = 0.03; I2: 62.6), body mass index (BMI) (SMD = -0.20; 95% CI, -0.35, -0.05; P = 0.01; I2: 60.6), fat mass (SMD = -0.32; 95% CI, -0.62, -0.03; P = 0.03; I2: 77.9) and waist circumference (WC) (SMD = -0.42; 95% CI, -0.68, -0.16; P = 0.001; I2: 75.2), and significantly increased lean mass (SMD = 1.21; 95% CI, 0.75, 1.67; P < 0.001; I2: 87.6). We found no significant effect of resveratrol administration on leptin (SMD = -0.20; 95% CI, -0.68, 0.27; P = 0.40; I2: 85.3) and adiponectin levels (SMD = 0.08; 95% CI, -0.39, 0.55; P = 0.74; I2: 91.0). Resveratrol supplementation significantly decreased body weight in obese patients (SMD -0.43; 95% CI, -0.60, -0.26) compared with other diseases (SMD 0.02; 95% CI, -0.29, 0.33), and type 2 diabetes mellitus (SMD -0.17; 95% CI, -0.37, 0.02). Overall, the current meta-analysis demonstrated that resveratrol intake significantly reduced weight, BMI, WC and fat mass, and significantly increased lean mass, but did not affect leptin and adiponectin levels.

Abstract
Background and objective: Oxidative stress and inflammation are key parameters in developing metabolic
disorders. Hence, antioxidant intake might be an appropriate approach. Several studies have evaluated the
effect of coenzyme Q10 (CoQ10) supplementation on lipid profile among patients with metabolic diseases,
though findings are controversial. The aim of this systematic review and meta-analysis was to determine the
effects of CoQ10 supplementation on lipid profile in patients with metabolic disorders.
Methods:
We searched PubMed, EMBASE, Web of Science and Cochrane Library databases until July 2017.
Prospective clinical trials were selected assessing the effect of CoQ10 supplementation on different biomarkers.
Two reviewers independently assessed the eligibility of studies, extracted data, and evaluated the risk of bias of
included studies. A fixed- or random-effects model was used to pool the data, which expressed as a standardized
mean difference with 95% confidence interval. Heterogeneity was measured using a Q-test and with I2 statistics.
Results:
A total of twenty-one controlled trials (514 patients and 525 controls) were included. The meta-analysis
indicated a significant reduction in serum triglycerides levels (SMD -0.28; 95% CI, -0.56, -0.005). CoQ10 supplementation
also decreased total-cholesterol (SMD -0.07; 95% CI, -0.45, 0.31), increased LDL- (SMD 0.04;
95% CI, -0.27, 0.36), and HDL-cholesterol levels (SMD 0.10; 95% CI, -0.32, 0.51), not statistically significant.
Conclusion:
CoQ10 supplementation may significantly reduce serum triglycerides levels, and help to improve
lipid profiles in patients with metabolic disorders. Additional prospective studies are recommended using higher
supplementation doses and longer intervention period.

Abstract
OBJECTIVE This systematic review and meta-analysis of randomized controlled trials (RCTs) was performed to summarize the effect of alpha-lipoic acid (ALA) supplementation on glycemic control and lipid profiles among patients with metabolic diseases. METHODS We searched the following databases till October 2017: MEDLINE, EMBASE, Web of Science and Cochrane Central Register of Controlled Trials. The relevant data were extracted and assessed for quality of the studies according to the Cochrane risk of bias tool. Data were pooled using the inverse variance method and expressed as standardized mean difference (SMD) with 95% confidence intervals (95% CI). Heterogeneity between studies was assessed by the Cochran Q statistic and I-squared tests (I2). Twenty-four studies were included in the meta-analyses. RESULTS The findings of this meta-analysis showed that ALA supplementation among patients with metabolic diseases significantly decreased fasting glucose (SMD -0.54; 95% CI, -0.89, -0.19; P = 0.003), insulin (SMD -1.01; 95% CI, -1.70, -0.31; P = 0.006), homeostasis model assessment of insulin resistance (SMD -0.76; 95% CI, -1.15, -0.36; P < 0.001) and hemoglobin A1c (SMD -1.22; 95% CI, -2.01, -0.44; P = 0.002), triglycerides (SMD -0.58; 95% CI, -1.00, -0.16; P = 0.006), total- (SMD -0.64; 95% CI, -1.01, -0.27; P = 0.001), low density lipoprotein-cholesterol (SMD -0.44; 95% CI, -0.76, -0.11; P = 0.008). We found no detrimental effect of ALA supplementation on high density lipoprotein-cholesterol (HDL-cholesterol) levels (SMD 0.57; 95% CI, -0.14, 1.29; P = 0.11). CONCLUSIONS Overall, the current meta-analysis demonstrated that ALA administration may lead to an improvement in glucose homeostasis parameters and lipid profiles except HDL-cholesterol levels.

Abstract
Alberta's Indigenous population is growing, yet health care access may be limited. This paper presents a comprehensive review on health care access among Indigenous populations in Alberta with a focus on the health care services use and barriers to health care access. Scientific databases (PubMed, EMBASE, CINAHL, and PsycINFO) and online search engines were systematically searched for studies and grey literature published in English between 2000 and 2013 examining health care services access, use and barriers to access among Indigenous populations in Alberta. Information on health care services use and barriers to use or access was synthesized based on the MOOSE guidelines. Overall, compared to non-Indigenous populations, health care use rates for hospital/emergency room services were higher and health care services use of outpatient specialists was lower among Indigenous peoples. Inadequate numbers of Indigenous health care professionals; a lack of cross-cultural training; fear of foreign environments; and distance from family and friends were barriers to health care use and access. Inequity in social determinants of health among Indigenous peoples and inadequate "health services with prevention approaches," may contribute to present health disparities between Indigenous and non-Indigenous populations in the province.

Abstract
Objective This systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to determine the effect of alpha-lipoic acid (ALA) supplementation on the inflammatory markers among patients with metabolic syndrome (MetS) and related disorders. Methods We searched the following databases until November 2017: PubMed, MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials. Three reviewers independently assessed study eligibility, extracted data, and evaluated risk of bias of included primary studies. Statistical heterogeneity was assessed using Cochran's Q test and I-square (I2) statistic. Data were pooled by using the random-effect model and standardized mean difference (SMD) was considered as the summary effect size. Results Eighteen trials out of 912 potential citations were found to be eligible for our meta-analysis. The findings indicated that ALA supplementation significantly decreased C-reactive protein (CRP) (SMD = - 1.52; 95% CI, - 2.25, - 0.80; P < 0.001), interlokin-6 (IL-6) (SMD = - 1.96; 95% CI, - 2.60, - 1.32; P < 0.001), and tumor necrosis factor alpha levels (TNF-α) (SMD = - 2.62; 95% CI, - 3.70, - 1.55; P < 0.001) in patients diagnosed with metabolic diseases. Conclusion In summary, the current meta-analysis demonstrated the promising impact of ALA administration on decreasing inflammatory markers such as CRP, IL-6 and TNF-α among patients with MetS and related disorders.

Abstract
BACKGROUND Several studies have evaluated the effect of inositol supplementation on lipid profiles among population with metabolic diseases; however, the findings are controversial. This review of randomized controlled trials (RCTs) was performed to summarize the evidence of the effects of inositol supplementation on lipid profiles among population with metabolic diseases. METHODS Relevant RCTs studies were searched in Cochrane Library, EMBASE, MEDLINE, and Web of Science until October 2017. Two researchers assessed study eligibility, extracted data, and evaluated risk of bias of included primary studies, independently. To check for the heterogeneity among included studies Q-test and I2 statistics were used. Data were pooled by using the random-effect model and standardized mean difference (SMD) was considered as summary of the effect size. RESULTS Overall, 14 RCTs were included into meta-analysis. Pooled results showed that inositol supplementation among patients with metabolic diseases significantly decreased triglycerides (SMD - 1.24; 95% CI, - 1.84, - 0.64; P < 0.001), total- (SMD - 1.09; 95% CI, - 1.83, - 0.55; P < 0.001), and LDL-cholesterol levels (SMD - 1.31; 95% CI, - 2.23, - 0.39; P = 0.005). There was no effect of inositol supplementation on HDL-cholesterol levels (SMD 0.20; 95% CI, - 0.27, 0.67; P = 0.40). CONCLUSIONS Inositol supplementation may result in reduction in triglycerides, total- and LDL-cholesterol levels, but did not affect HDL-cholesterol levels among patients with metabolic diseases. Additional prospective studies regarding the effect of inositol supplementation on lipid profiles in patients with metabolic diseases are necessary.

Abstract
BACKGROUND Dietary habits formed during youth may result in the development of obesity and chronic diseases in adulthood. We aimed to determine the frequency of the consumption of foods and beverages and the degree of adherence to Canada's Food Guide recommendations among multi-ethnic youths. METHODS Participants were recruited from 12 schools in the Edmonton, Alberta area by use of posters, school newsletters and advertisements. A 30-item food frequency questionnaire was administered by a trained interviewer to assess dietary intake in a convenience sample of 557 (328 females and 229 males) youths aged 11-23 years; for the purpose of the present study, only the 14-18 years age group was considered in the analysis. Participants were divided by sex and self-identified ethnicity into four groups [Indigenous, African & Middle Eastern (AME), Asian, and European]. Statistical analysis of the data was undertaken using t-tests, Welch's analysis of variance and Games-Howell tests. P < 0.05 was considered statistically significant. RESULTS Vegetables and Fruit recommendations were the least likely to be followed, with 90.7-96.8% of participants in all groups not consuming the recommended number of servings day-1 . The mean frequency of fruit consumption was lower among Indigenous youths compared to Asian youths (0.90 versus 1.37 times day-1 ). A greater proportion of males than females (55.9% versus 44.3%) did not meet the minimum recommendations for Meat and Alternatives (P = 0.016). The percentage of youths not adhering to recommendations for Milk and Alternatives was 81.7% for Indigenous, 73.3% for AME, 78.6% for Asian and 63.5% for European youths. Indigenous youths more frequently consumed potato chips and soft drinks compared to other ethnic youths. The most frequently consumed beverage was milk (1.25 times day-1 ). CONCLUSIONS The majority of youths did not consume minimum daily recommended servings of Vegetables and Fruit, Milk and Alternatives, and/or Meat and Alternatives food groups. Evidence-based dietary interventions and public health strategies are needed.

Abstract
The current systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to summarize the effect of vitamin D supplementation on biomarkers of inflammation and oxidative stress among women with polycystic ovary syndrome (PCOS). Cochrane library, Embase, PubMed, and Web of Science database were searched to identify related randomized-controlled articles (RCTs) published up to November 2017. Two researchers assessed study eligibility, extracted data, and evaluated risk of bias of included RCTs, independently. To check heterogeneity Q-test and I2 statistics were used. Data were pooled by using the random-effect model and standardized mean difference (SMD) was considered as summary effect size. Seven RCTs were included into our meta-analysis. The findings showed that vitamin D supplementation in women with PCOS significantly decreased high-sensitivity C-reactive protein (hs-CRP) (SMD -1.03; 95% CI, -1.58, -0.49; p <0.001) and malondialdehyde (MDA) (SMD -1.64, 95% CI -2.26 to -1.02, p <0.001), and significantly increased total antioxidant capacity (TAC) levels (SMD 0.86, 95% CI 0.08 to 1.64, p=0.03). Vitamin D supplementation had no significant effect on nitric oxide (NO) (SMD 0.11, 95% CI -0.44 to 0.66, p=0.69) and total glutathione (GSH) levels (SMD 0.54, 95% CI -0.20 to 1.28, p=0.15). Overall, the current meta-analysis demonstrated that vitamin D supplementation to women with PCOS resulted in an improvement in hs-CRP, MDA and TAC, but did not affect NO and GSH levels.

Heterogeneity between studies was assessed by the Cochran Q statistic and I-squared tests (I2). Overall, 14 studies were included in the meta-analyses. Fourteen RCTs with 473 subjects were included in our meta-analysis. The results indicated that the supplementation with ginger significantly decreased body weight (BW) (SMD -0.66; 95% CI, -1.31, -0.01; P = 0.04), waist-to-hip ratio (WHR) (SMD -0.49; 95% CI, -0.82, -0.17; P = 0.003), hip ratio (HR) (SMD -0.42; 95% CI, -0.77, -0.08; P = 0.01), fasting glucose (SMD -0.68; 95% CI, -1.23, -0.05; P = 0.03) and insulin resistance index (HOMA-IR) (SMD -1.67; 95% CI, -2.86, -0.48; P = 0.006), and significantly increased HDL-cholesterol levels (SMD 0.40; 95% CI, 0.10, 0.70; P = 0.009). We found no detrimental effect of ginger on body mass index (BMI) (SMD -0.65; 95% CI, -1.36, 0.06; P = 0.074), insulin (SMD -0.54; 95% CI, -1.43, 0.35; P = 0.23), triglycerides (SMD -0.27; 95% CI, -0.71, 0.18; P = 0.24), total- (SMD -0.20; 95% CI, -0.58, 0.18; P = 0.30) and LDL-cholesterol (SMD -0.13; 95% CI, -0.51, 0.24; P = 0.48). Overall, the current meta-analysis demonstrated that ginger intake reduced BW, WHR, HR, fasting glucose and HOMA-IR, and increased HDL-cholesterol, but did not affect insulin, BMI, triglycerides, total- and LDL-cholesterol levels.

Abstract
Although several studies have evaluated the effect of folate supplementation on diabetes biomarkers among patients with metabolic diseases, findings are inconsistent. This review of randomized controlled trials (RCTs) was performed to summarize the evidence on the effects of folate supplementation on diabetes biomarkers among patients with metabolic diseases. Randomized-controlled trials (RCTs) published in PubMed, EMBASE, Web of Science and Cochrane Library databases up to 1 September 2017 were searched. Two review authors independently assessed study eligibility, extracted data, and evaluated risk of bias of included studies. Heterogeneity was measured with a Q-test and with I2 statistics. Data were pooled by using the fix or random-effect model based on the heterogeneity test results and expressed as standardized mean difference (SMD) with 95% confidence interval (CI). A total of sixteen randomized controlled trials involving 763 participants were included in the final analysis. The current meta-analysis showed folate supplementation among patients with metabolic diseases significantly decreased insulin (SMD -1.28; 95% CI, -1.99, -0.56) and homeostasis model assessment of insulin resistance (HOMA-IR) (SMD -1.28; 95% CI, -1.99, -0.56). However, folate supplementation did not affect fasting plasma glucose (FPG) (SMD -0.30; 95% CI, -0.63, 0.02) and hemoglobin A1C (HbA1c) (SMD -0.29; 95% CI, -0.61, 0.03). The results of this meta-analysis study demonstrated that folate supplementation may result in significant decreases in insulin levels and HOMA-IR score, but does not affect FPG and HbA1c levels among patients with metabolic diseases.

Abstract
INTRODUCTION Although several trials have assessed the effect of coenzyme Q10 (CoQ10) supplementation on blood pressures among patients with metabolic diseases, findings are controversial. AIM This review of randomized controlled trials (RCTs) was performed to summarize the evidence on the effects of CoQ10 supplementation on blood pressures among patients with metabolic diseases. METHODS Randomized-controlled trials (RCTs) published in PubMed, EMBASE, Web of Science and Cochrane Library databases up to 10 August 2017 were searched. Two review authors independently assessed study eligibility, extracted data, and evaluated risk of bias of included studies. Heterogeneity was measured with a Q-test and with I2 statistics. Data were pooled by using the fix or random-effect model based on the heterogeneity test results and expressed as standardized mean difference (SMD) with 95% confidence interval (CI). RESULTS A total of seventeen randomized controlled trials (684 participants) were included. Results showed that CoQ10 supplementation significantly decreased systolic blood pressure (SBP) (SMD - 0.30; 95% CI - 0.52, - 0.08). However, CoQ10 supplementation decreased diastolic blood pressure (DBP), but this was not statistically significant (SMD - 0.08; 95% CI - 0.46, 0.29). CONCLUSIONS CoQ10 supplementation may result in reduction in SBP levels, but did not affect DBP levels among patients with metabolic diseases. Additional prospective studies regarding the effect of CoQ10 supplementation on blood pressure in patients with metabolic diseases are necessary.

Abstract
BACKGROUND A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to summarize the evidence on the effect of vitamin D supplementation on metabolic profiles in patients with non-alcoholic fatty liver disease (NAFLD). METHODS We systematically searched PubMed, EMBASE and five other databases to identify all RCTs investigating the association between vitamin D and NAFLD up until 5 October 2016. Seven RCTs with 452 participants (227 patients and 225 controls) were included in the meta-analysis. RESULTS The results showed that vitamin D administration had no beneficial effect on fasting plasma glucose (FPG) (standardized mean difference [SMD]-0.23; 95% confidence interval [CI], -0.88, 0.42), insulin (SMD -1.09; 95% CI, -2.70,0.52) and homeostasis model assessment of insulin resistance (HOMA-IR) (SMD -1.89; 95% CI, -3.88,0.09). Vitamin D supplementation also had no effect on lipid profiles including triglycerides (SMD -0.36; 95% CI, -1.77, 1.04), and total-cholesterol (SMD -0.46; 95% CI: -1.3, 0.39), as well as on aspartate transaminase (AST) (SMD -0.53; 95% CI, -1.11, 0.05), alanine aminotransferase (ALT) (SMD -0.66; 95% CI, -1.43,0.11), and body mass index (BMI) (SMD -0.25; 95% CI, -0.76,0.27). CONCLUSIONS Vitamin D supplementation had no effect on FPG, insulin, HOMA-IR, triglycerides, total-, LDL-cholesterol, AST, ALT, and BMI.

Abstract
This systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to summarize the effect of selenium administration on glucose metabolism and lipid profiles among patients with diseases related to metabolic syndrome (MetS). We searched the following databases up to May 2017: MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials. The relevant data were extracted and assessed for quality of the studies according to the Cochrane risk of bias tool. Data were pooled using the inverse variance method and expressed as standardized mean difference (MDs) with 95% confidence intervals (95% CI). Five studies were included in the meta-analyses. The results showed that selenium supplementation significantly reduced insulin levels (SMD -0.42; 95% CI, -0.83 to -0.01) and increased quantitative insulin sensitivity check index (QUICKI) (SMD 0.83; 95% CI, 0.58 to 1.09). Selenium supplementation had no beneficial effects on other glucose homeostasis parameters, such as fasting plasma glucose (FPG) (SMD -0.29; 95% CI, -0.73 to 0.15), homeostasis model assessment of insulin resistance (HOMA-IR) (SMD -0.80; 95% CI, -1.58 to -0.03), and lipid profiles, such as triglycerides (SMD -0.42; 95% CI, -0.83 to -0.01), VLDL- (SMD -0.42; 95% CI, -0.83 to -0.01), total- (SMD -0.42; 95% CI, -0.83 to -0.01), LDL- (SMD 0.02; 95% CI, -0.20 to 0.24), and HDL-cholesterol (SMD 0.16; 95% CI, -0.06 to -0.38). Overall, this meta-analysis showed that selenium administration may lead to an improvement in insulin and QUICKI, but did not affect FPG, HOMA-IR, and lipid profiles.

Abstract
BACKGROUND Chronic pain is common and can be challenging to manage. Despite increased utilisation of opioids, the safety and efficacy of long-term use of these compounds for chronic non-cancer pain (CNCP) remains controversial. This overview of Cochrane Reviews complements the overview entitled 'High-dose opioids for chronic non-cancer pain: an overview of Cochrane Reviews'. OBJECTIVES To provide an overview of the occurrence and nature of adverse events associated with any opioid agent (any dose, frequency, or route of administration) used on a medium- or long-term basis for the treatment of CNCP in adults. METHODS We searched the Cochrane Database of Systematic Reviews (the Cochrane Library) Issue 3, 2017 on 8 March 2017 to identify all Cochrane Reviews of studies of medium- or long-term opioid use (2 weeks or more) for CNCP in adults aged 18 and over. We assessed the quality of the reviews using the AMSTAR criteria (Assessing the Methodological Quality of Systematic Reviews) as adapted for Cochrane Overviews. We assessed the quality of the evidence for the outcomes using the GRADE framework. MAIN RESULTS We included a total of 16 reviews in our overview, of which 14 presented unique quantitative data. These 14 Cochrane Reviews investigated 14 different opioid agents that were administered for time periods of two weeks or longer. The longest study was 13 months in duration, with most in the 6- to 16-week range. The quality of the included reviews was high using AMSTAR criteria, with 11 reviews meeting all 10 criteria, and 5 of the reviews meeting 9 out of 10, not scoring a point for either duplicate study selection and data extraction, or searching for articles irrespective of language and publication type. The quality of the evidence for the generic adverse event outcomes according to GRADE ranged from very low to moderate, with risk of bias and imprecision being identified for the following generic adverse event outcomes: any adverse event, any serious adverse event, and withdrawals due to adverse events. A GRADE assessment of the quality of the evidence for specific adverse events led to a downgrading to very low- to moderate-quality evidence due to risk of bias, indirectness, and imprecision.We calculated the equivalent milligrams of morphine per 24 hours for each opioid studied (buprenorphine, codeine, dextropropoxyphene, dihydrocodeine, fentanyl, hydromorphone, levorphanol, methadone, morphine, oxycodone, oxymorphone, tapentadol, tilidine, and tramadol). In the 14 Cochrane Reviews providing unique quantitative data, there were 61 studies with a total of 18,679 randomised participants; 12 of these studies had a cross-over design with two to four arms and a total of 796 participants. Based on the 14 selected Cochrane Reviews, there was a significantly increased risk of experiencing any adverse event with opioids compared to placebo (risk ratio (RR) 1.42, 95% confidence interval (CI) 1.22 to 1.66) as well as with opioids compared to a non-opioid active pharmacological comparator, with a similar risk ratio (RR 1.21, 95% CI 1.10 to 1.33). There was also a significantly increased risk of experiencing a serious adverse event with opioids compared to placebo (RR 2.75, 95% CI 2.06 to 3.67). Furthermore, we found significantly increased risk ratios with opioids compared to placebo for a number of specific adverse events: constipation, dizziness, drowsiness, fatigue, hot flushes, increased sweating, nausea, pruritus, and vomiting.There was no data on any of the following prespecified adverse events of interest in any of the included reviews in this overview of Cochrane Reviews: addiction, cognitive dysfunction, depressive symptoms or mood disturbances, hypogonadism or other endocrine dysfunction, respiratory depression, sexual dysfunction, and sleep apnoea or sleep-disordered breathing. We found no data for adverse events analysed by sex or ethnicity. AUTHORS' CONCLUSIONS A number of adverse events, including serious adverse events, are associated with the medium- and long-term use of opioids for CNCP. The absolute event rate for any adverse event with opioids in trials using a placebo as comparison was 78%, with an absolute event rate of 7.5% for any serious adverse event. Based on the adverse events identified, clinically relevant benefit would need to be clearly demonstrated before long-term use could be considered in people with CNCP in clinical practice. A number of adverse events that we would have expected to occur with opioid use were not reported in the included Cochrane Reviews. Going forward, we recommend more rigorous identification and reporting of all adverse events in randomised controlled trials and systematic reviews on opioid therapy. The absence of data for many adverse events represents a serious limitation of the evidence on opioids. We also recommend extending study follow-up, as a latency of onset may exist for some adverse events.

Abstract
This systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to summarize the effect of vitamin D supplementation on glucose homeostasis parameters and lipid profiles in gestational diabetes (GDM) patients. We conducted an electronic systematic search of MEDLINE, and 4 other research databases from inception to August 2016, in addition to performing hand searches and consulting with experts in the field. The index of heterogeneity between studies was determined using Cochran (Q) and I-squared tests. Given the existing heterogeneity between studies, a fix or random effect model was performed to estimate the standardized mean difference (SMD) for each variable by using inverse variance method and Cohen statistics. Six randomized clinical trials (187 subjects and 184 controls) were included. The results showed that vitamin D supplementation significantly reduced the homeostasis model assessment of insulin resistance (HOMA-IR) [SMD -0.66; 95% confidence interval (CI), -1.14 to -0.18], homeostatic model assessment-B cell function (HOMA-B) (SMD -0.52; 95% CI, -0.79 to -0.25), LDL-cholesterol levels (SMD -0.33; 95% CI, -0.58 to -0.07), and significantly increased quantitative insulin sensitivity check index (QUICKI) (SMD 0.73; 95% CI, 0.26 to 1.20). We found no beneficial effect of vitamin D supplementation on fasting plasma glucose (FPG), insulin, HbA1c, total-, HDL-cholesterol, and triglycerides concentrations. In conclusion, this meta-analysis demonstrated that vitamin D supplementation may lead to an improvement in HOMA-IR, QUICKI, and LDL-cholesterol levels, but did not affect FPG, insulin, HbA1c, triglycerides, total- and HDL-cholesterol levels; however, vitamin D supplementation increased HOMA-B.
