Effect of vitamin D on clinical outcomes in patients with thermal injury.

Evaluating complications and mortality risks in burn patients is crucial for effective treatment planning and improving survival rates. This study investigated the relationship between the serum vitamin D level and the clinical outcomes of adult burns patients. This was a prospective cohort of adult patients hospitalized due to thermal burns at a burn centre in the north of Iran. Based on the level of 25 hydroxyvitamin D measured upon admission, patients were divided into two groups of patients with sufficient 25 hydroxyvitamin D level and insufficient 25 hydroxyvitamin D level. Descriptive statistics were used for baseline demographics. Univariate analysis was conducted using Mann-Whitney U, Chi-square, independent samples, and Fisher's exact tests. A multivariate logistic regression was performed to adjust for the effects of confounding variables. Statistical analyses were conducted using SPSS 28.0 software. A total of 220 patients were included in the study. The average total body surface area burned was 30.52 ± 9.34. Patients with insufficient vitamin D levels had longer hospital stays (12.53 vs. 11.45) and longer stays in the intensive care unit (ICU) (3.32 vs. 2.40) than those with appropriate vitamin D levels. Participants with insufficient vitamin D levels exhibited a numerically higher incidence of infections than those with adequate levels (p < 0.05). The multivariate regression found that vitamin D deficiency levels were associated with increased infection rates and prolonged hospital stay. This study suggests that vitamin D deficiency is a significant risk factor for adverse clinical outcomes in burn patients. Further research is needed to confirm these associations and to explore potential interventions to optimize vitamin D status in this patient population.

The Effect of an Educational Intervention Based on the Health Belief Model (HBM) on Nutritional Performance Related to Gastric Cancer in Rural Women in Northern Regions of Iran.

Gastric cancer is a common cause of cancer death in the world. This study examined 120 rural women. The educational program included four sessions for each group based on the health belief model. The mean age of the women was 34.51 ± 9.16. The mean score of the perceived barriers significantly decreased in the experimental group (11.08 ± 0.37) compared to the control group (14.92 ± 0.42) (P < .001), and the mean score of knowledge, performance and HBM constructs, increased significantly 2 months after the education (P < .001).It is recommended that educational interventions be designed by HBM to improve nutritional behaviors related to GC in the female population.

The effect of probiotic and synbiotic supplementation on appetite-regulating hormones and desire to eat: A systematic review and meta-analysis of clinical trials.

Recent studies have demonstrated the effect of probiotics, prebiotics, and synbiotics on adiponectin and leptin levels; however, those findings remain contested. The present study aimed to explore the impact of probiotics/synbiotics on appetite-regulating hormones and the desire to eat. METHODS: A systematic review was conducted by searching the Medline (PubMed) and Scopus databases from inception to December 2021, using relevant keywords and MeSH terms, and appropriate randomized controlled trials (RCTs) were extracted. The standardized mean differences (SMD) and 95% confidence intervals (95%CIs) were calculated as part of the meta-analysis using a random-effect model to determine the mean effect sizes. Analysis of Galbraith plots and the Cochrane Chi-squared test were conducted to examine heterogeneity. RESULTS: Meta-analysis of data from a total of 26 RCTs (n = 1536) showed a significant decrease in serum/plasma leptin concentration following probiotic/synbiotic supplementation (SMD: -0.38, 95%CI= -0.638, -0.124); P-value= 0.004; I2= 69.4%; P heterogeneity < 0.001). The leptin level decrease from probiotic/synbiotic supplementation was higher in patients with NAFLD than those with overweight/obesity or type 2 diabetes mellitus/ metabolic syndrome/ prediabetes. Probiotic/synbiotic supplementation was associated with a trending increase in adiponectin levels, stronger in patients with type 2 diabetes mellitus, metabolic syndrome, and prediabetes (SMD: 0.25, 95%CI= 0.04, 0.46) µg/mL; P-value= 0.021; I2 = 16.8%; P heterogeneity= 0.30). Additionally, supplementation with probiotic/synbiotic was linked to a slight increase in desire to eat (SMD: 0.34, 95%CI= 0.03, 0.66) P-value = 0.030; I2 = 39.4%; P heterogeneity= 0.16). CONCLUSION: Our meta-analysis indicates a favorable impact of probiotic/synbiotic supplementation on regulating leptin and adiponectin secretion.

Evaluation of cardiometabolic risk markers linked to reduced left ventricular ejection fraction (LVEF) in patients with ST-elevation myocardial infarction (STEMI).

BACKGROUND: It is well established that left ventricular systolic dysfunction (LVSD), as marked by reduced left ventricular ejection fraction (LVEF), notably worsens the prognosis of ST-elevation myocardial infarction (STEMI). However, the link between cardiometabolic risk markers and LVSD seems unclear. This study aimed to investigate the differences in variables affecting reduced LVEF in STEMI patients. METHODS: In the current retrospective study, 200 consecutive STEMI patients were enrolled between April 2016 to January 2017. Analysis of serum parameters, anthropometric evaluation, and echocardiography was performed after admission. The participants were categorized according to LVEF levels as follows: group1 (normal: 50-70%, n = 35), group2 (mildly reduced: 40-49%, n = 48); group3 (moderately reduced: 30-39%, n = 94) and group4 (severely reduced: < 30%, n = 23). Between-group comparisons were made using the Kruskal-Wallis test. RESULTS: Overall, of 200 STEMI patients with a mean age of 62 years, 27%(n = 54) were females. The median of BMI of patients in group4 (31.07 kg/m2) was significantly higher than group3 (26.35 kg/m2), group2 (25.91 kg/m2), and group1 (24.98 kg/m2; P value < 0.0001). Group4 patients showed significantly increased fasting blood sugar (FBS) than groups 1 (212.00, vs. 139.00 mg/dl; P value = 0.040). Patients in groups 1 and 2 exerted significantly elevated triglyceride levels than those in group4 (142.00, 142.50, and 95.00 mg/dl; P value = 0.001). WBC count, neutrophil%, and neutrophil to lymphocyte ratio among those in group1 (10,200/m3, 70.00%, and 2.92, respectively) were significantly lower than group4 (12,900/m3, 83.00%, and 5.47, respectively; P value < 0.05). CONCLUSION: These findings highlight higher BMI, FBS, and leucocyte count linked to LVSD, probably through increasing the inflammation and reducing LVEF levels. More extensive studies are needed to clarify the clinical relevance of these results.

Evaluating the use of novel atherogenicity indices and insulin resistance surrogate markers in predicting the risk of coronary artery disease: a case‒control investigation with comparison to traditional biomarkers.

BACKGROUND: Due to the contribution of coronary artery disease (CAD) to serious cardiovascular events, determining biomarkers that could robustly predict its risk would be of utmost importance. Thus, this research was designed to assess the value of traditional cardio-metabolic indices, and more novel atherogenicity indices and insulin resistance surrogate markers in the identification of individuals at risk of CAD. METHODS: A case‒control survey was conducted, in which 3085 individuals were enrolled. Their clinical and biochemical data were gathered at baseline. The investigated indices included the atherogenic index of plasma (AIP), triglyceride-glucose (TyG) index, TyG-body mass index (TyG-BMI), lipoprotein combine index (LCI), cholesterol index (CHOLINDEX), Castelli's risk indices-I, II (CRI-I, CRI-II), and metabolic score for insulin resistance (METS - IR). To examine the relationship between these variables and CAD risk, multiple regression analyses adjusted for potential confounders were conducted. RESULTS: Overall, 774 angiographically confirmed CAD patients (mean age = 54 years) were compared with 3085 controls (mean age = 51 years). Higher triglyceride, total cholesterol and fasting blood sugar levels and lower HDL-C levels were related to an elevated risk of CAD (P-for-trend < 0.001), while the direct association between increased serum LDL-C concentrations and a greater risk of CAD only became apparent when excluding those with diabetes, and statin users. Among novel indices, greater values of the majority of these markers, including AIP, CRI-I, and -II, CHOLINDEX, LCI, and TyG-index, in comparison to the lower values, significantly elevated CAD risk (P-for-trend < 0.001). CONCLUSION: According to the current findings, novel atherogenicity indices and insulin resistance surrogate markers, in particular, AIP, CRI-I and II, CHOLINDEX, LCI, and TyG-index, may be useful in predicting CAD risk.

Stages of dairy product consumption among Iranian female high school students based on transtheoretical model: The case of osteoporosis prevention.

Background: As nutritional needs increase in adolescence, dairy consumption can play a key role in health and disease prevention; however, unfortunately, inadequate consumption of milk and dairy products has often been reported in adolescents. Aim: The purpose of this study was to investigate the relation between decisional balance, self-efficacy, and the processes of change with the stages of change for dairy consumption in female high school students in Shaft county located in the west of Gilan Province, Iran. Methods: A total of 385 female high school students in Shaft County were studied through the census method in 2019. The data collection instrument was a valid and reliable questionnaire consisting of demographic information, stages of change and items of transtheoretical model constructs including the processes of change (cognitive process: consciousness-raising, dramatic relief, self-reevaluation, environmental reevaluation, and social liberation; behavioral process: self-liberation, counter conditioning, reinforcement management, stimulus control and helping relationships), decisional balance and self-efficacy. Data were analyzed using SPSS 21 software. Results: A total of 208 (54%), 53 (13.8%), 56 (14.5%), 32 (8.3%) and 36 (9.4%) students were in the pre-contemplate, contemplation, preparation, action and maintenance stages, respectively. As the subjects progressed through the stage of change for dairy consumption, an increase in the mean score of self-efficacy, decisional balance, and processes of change was observed (P < 0.01). Conclusion: The constructs of the transtheoretical model should be considered in designing educational interventions to promote dairy consumption with regard to the stage of change for dairy consumption in the subjects.

The Effects of Probiotics on Inflammation, Endothelial Dysfunction, and Atherosclerosis Progression: A Mechanistic Overview.

INTRODUCTION: The relationship between the intestinal microbiota dysbiosis, inflammation, and cardiovascular disorders (CVDs) has become evident, based on a growing body of literature from animal models and human studies. On the other hand, probiotics are believed to have promising effects on modifying dysbiosis and protecting against CVDs. OBJECTIVE: This narrative review provides an overview of the link between gut microbiota, inflammation, endothelial dysfunction, and atherosclerosis. The influences of probiotic supplementation on biomarkers contributing to these conditions as the primary underlying risk factors for developing CVDs are also discussed. METHODS: An up-to-date review was performed of the available evidence from experimental studies, clinical trials, and meta-analyses, considering their challenges and limitations. It also aimed to provide mechanistic insight into the likely mechanisms of probiotics that could prevent atherosclerosis initiation and progression. RESULTS: Probiotic supplementation seems to be associated with reduced levels of inflammation and oxidative stress biomarkers (C-reactive protein, tumour necrosis factor-α, interleukin (IL)-6, IL-12, and malondialdehyde). Further, these agents might enhance antioxidant factors (IL-10, total antioxidant status, total antioxidant capacity, glutathione, and nitric oxide). Probiotics also appear to improve intestinal barrier integrity, reduce leakage of harmful metabolites (e.g., lipopolysaccharides), inhibit pro-inflammatory signalling pathways, and possibly suppress the formation of trimethylamine/trimethylamine oxide. Probiotics have also been found to enhance endothelial function and halter thrombosis. CONCLUSION: The current clinical evidence underlines belief that probiotics might be associated with reduced levels of inflammation biomarkers. Experimental evidence reports that the beneficial effects of probiotics seem to be mainly imposed by triggering the secretion of short-chain fatty acids and bile acids, in addition to suppressing the NF-κB signalling pathway. However, the current studies are still in their infancy and it is of high priority to design further research on the topic.

Rice bran oil could favorably ameliorate atherogenicity and insulin resistance indices among men with coronary artery disease: post hoc analysis of a randomized controlled trial.

BACKGROUND: Despite recent advances in recognizing more reliable indicators to estimate the coronary artery disease (CAD) patients' response to treatment and prognosis, less attention has been paid to evaluating them in clinical trials. Hence, the present research was conducted to study the impact of rice bran oil (RBO) versus sunflower oil (SFO) on various atherogenicity and insulin resistance markers. METHODS: In the present 8-week randomized controlled trial, 40 CAD men with an average age of 56 years were allocated randomly into the intervention or control group to use RBO or SFO (30 g/day) plus a standardized dietary plan. As a further analysis, eight atherosclerosis-related indices were calculated before and after the study. RESULTS: Analysis of covariance test in which potential confounders and baseline levels were considered, indicated that using RBO compared to SFO reduced Castelli's risk index I and II (adjusted means:3.29, 1.52 vs. 4.61, 2.20, respectively), atherogenic coefficient (2.29 vs. 3.61), lipoprotein combine index (6.54 vs. 17.53), and cholesterol index (0.46 vs. 1.20) after the trial (P-value ≤ 0.002). Also, the RBO group yielded significantly lower triglyceride glucose index (8.73 vs. 9.13) (P-value = 0.010). Further, marginally significant amelioration in triglyceride/HDL ratio and atherogenic index of plasma (1.48 and 0.13 vs. 1.86 and 0.24 respectively) were noted (P-value = 0.07). Spearman correlation analysis detected significant positive correlations between alterations in TNF-α serum levels (ng/L) and the majority of evaluated indices (P-value < 0.05). CONCLUSION: Taken together, incorporating 30 g of RBO into the patient's usual diet appeared effective in ameliorating atherogenicity and insulin resistance indicators among men with CAD, probably in relation to its anti-inflammatory properties. TRIAL REGISTRATION: The protocol of the current trial was retrospectively recorded in the Iranian clinical trial registration system (IRCT) with the registration number of IRCT20190313043045N1 (URL: https://en.irct.ir/trial/38346 ; Registration date: 2019-04-27).

Melissa officinalis tea favourably affects the frequency of premature ventricular beats and cardiometabolic profile among patients with premature ventricular contraction: A randomised open-label controlled trial.

BACKGROUND AND AIMS: Premature ventricular contraction (PVC) as one of the most common arrhythmias could worsen the morbidity of cardiovascular events, particularly concurrent with other risk factors. Considering the probable side effects of antiarrhythmic drugs chronic use, prescribing herbal medicines for such conditions is on the rise. Melissa officinalis (MO) is widely identified as an antiarrhythmic and cardioprotective agent but there is limited evidence for its clinical use. This research, thus, aimed to investigate the effects of MO tea among patients with PVCs. METHODS: The present 12-week randomised controlled trial enrolled 60 patients with confirmed diagnosis of moderate to low-grade PVCs. The patients in intervention group received MO teabags (containing 2-g dried leaves/250 mL in hot water) two times/day in addition to lifestyle modification recommendations, while control group only received lifestyle modification recommendations. After collecting the data, blood samples were gathered to explore serum concentrations of glucose and lipid markers. The number of premature ventricular beats and heart rates was determined by 24-hour rhythm Holter monitoring. RESULTS: On average, the patients aged 47 years and approximately 67.8% (n = 40) were women. The ANCOVA adjusted for baseline values and confounders revealed that patients in the MO tea group had significantly lower concentrations of triglyceride (adjusted mean (AM) = 144.75 mg/dL), total cholesterol (AM = 155.35 mg/dL), and fasting blood sugar (AM = 90.85 mg/dL), compared with the controls (AM = 174.27, 171.99, 99.84 mg/dL, respectively (P-value ≤.042). However, the intervention failed to affect LDL-C and HDL-C levels significantly. Significantly reduced frequency of 24-hour premature ventricular beats in the MO tea group (AM = 2142.39) was also noted compared with the controls (AM = 3126.05); (P-value = .017). The 24-hour heartbeats showed only a significant decrease within the intervention group (P-value < .01). CONCLUSION: Together, these results seem to support the higher cardioprotective effects of MO as a medicinal plant than lifestyle modifications alone. Nevertheless, further exploration of this hypothesis is warranted using large-scaled clinical trials.

Food insecurity status and associated factors among rural households in the north of Iran.

BACKGROUND: Iran has been experiencing an accelerated change in the nutrition and health of its people, which has led to considerable variations in the country's nutritional status. Little is known about the food insecurity status in the north of Iran. AIM: The present study aimed to investigate the food insecurity status and factors associated with it in a rural area in the north of Iran. METHODS: This cross-sectional study was conducted among 573 rural households in Guilan Province in the north of Iran. The food insecurity status of the households was measured using the Household Food Insecurity Access Scale. Data on the demographic characteristics of the households and their depression status were collected by interviewing the heads of the households. The socioeconomic status index of the households was constructed using factor analysis, and a multivariate ordinal logistic regression model was used to estimate the adjusted odds ratio of the independent predictors of food insecurity. RESULTS: The results indicated that approximately half of the households (50.8%) had experienced mild (43.2%), moderate (6.5%) or severe (1.1%) food insecurity. The multivariate model showed that sex, age, depression status of the head of the household and having a patient with a chronic condition in the household were independently associated with food security status. CONCLUSIONS: This study showed that food insecurity was highly prevalent among rural households in the north of Iran. The study concludes that interventions with the aim of reducing the prevalence of food insecurity, depression and chronic diseases in the area can be effective in improving the nutritional status of the households.

Copper, magnesium, zinc and calcium status in osteopenic and osteoporotic post-menopausal women.

Copper, magnesium, zinc and calcium status were measured in postmenopausal women with osteoporosis (n = 23) and osteopenia (n = 28) as classified on the basis of the T-score of the femur neck and dual energy X-ray absorptiometry results. Anthropometric indices, dietary intake and serum copper, magnesium, zinc and calcium were assessed. The results of our study showed that the mean dietary intake of magnesium, zinc and calcium in post-menopausal women with low bone density were significantly lower than recommended dietary allowance. The mean serum levels of zinc (P = 0.001) and copper (P = 0.000) were significantly lower than normal range and 40.4% of this participants had serum magnesium levels lower than normal range. No statistically significant differences were observed between the osteopenic and osteoporotic groups with respect to serum levels and dietary intakes of copper, calcium, magnesium and zinc. Due to the mineral deficiency in post-menopausal women with low bone density and the key role of minerals on bone health, supplementation with magnesium, calcium, zinc and perhaps copper recommended.

A comparative study of the effectiveness of self-management and group management on the amount of weight loss of nurses under low-calorie diet treatment: A simultaneous mixed-methods study.

BACKGROUND: Nursing is a profession that is associated with a lot of stress and a risk of being overweight or obese. The purpose of this research was to determine the comparative effectiveness of self-management (self-M) and group management (group-M) on nurses who were following a diet with the aim of proposing a proper planning and a healthy lifestyle for them. MATERIALS AND METHODS: This study was a simultaneous mixed-methods design (interventional and qualitative). The participants were all overweight or obese nurses working in teaching hospitals at Guilan University of Medical Sciences in 2019 (n = 96). In the qualitative part, data were extracted from semi-structured interviews. For quantitative data analysis, relevant statistical methods such as Kolmogorov-Smirnov test, analysis of variance (ANOVA), and analysis of covariance (ANCOVA) were used. For qualitative data analysis, the conventional content analysis approach was used and Lincoln and Guba's criteria were applied to ensure the accuracy of the data. RESULTS: In both quantitative and qualitative sections, the results showed that following a diet treatment with group-M is more effective than self-M. CONCLUSION: The results showed that a healthy lifestyle can be achieved for nurses if they participate in training classes and group programs, which are proven to be effective based on this article and some other studies. Also, since weight gain and obesity, as one of the most important problems of health systems, continue to increase and can impose a heavy economic and social burden on human societies, various general policies should be used and these solutions can range from home to society to prevent and control them.

Effect of garlic powder tablet on carotid intima-media thickness in patients with coronary artery disease: a preliminary randomized controlled trial.

BACKGROUND/OBJECTIVES: This study was designed to investigate whether garlic powder tablets in adjunct to conventional medical treatment could have an effect on carotid intima-media thickness (CIMT) and plasma lipoproteins and lipids in patients with coronary artery disease (CAD). SUBJECTS/METHODS: A randomized, placebo-controlled, clinical trial was conducted on 56 patients with CAD between the ages of 25 and 75 years. The patients were randomly divided into two groups: garlic group (n = 27), receiving garlic powder tablet (1200 µg allicin/tab) twice daily and the placebo group (n = 29), receiving placebo for 3 months. The rate of atherosclerosis progression was measured by B-mode ultrasonography as the increase in CIMT. RESULTS: After 3 months of taking garlic tablets, CIMT values had minor variations (0.009 ± 0.007 mm reduction from baseline), while in the placebo group, an increase in CIMT values was observed (0.04 ± 0.01 mm increase from baseline). After 3 months of treatment, mean CIMT difference from baseline was significantly differ between the two groups (p < 0.001). Plasma lipids and lipoproteins (total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, Apolipoprotein A1 and Apolipoprotein B) did not differ between the two groups. CONCLUSIONS: The results suggest that dry garlic powder tablet is superior to placebo in prevention of CIMT progression in patients with CAD and may be considered as an adjunct treatment for atherosclerosis.

Effects of Flaxseed Oil and Olive Oil on Markers of Inflammation and Wound Healing in Burn Patients: A Randomized Clinical Trial.

Objectives: To study the anti-inflammatory and antioxidant effects of flaxseed oil and olive oil on inflammatory markers for facilitating wound healing. Methods: One hundred and twelve patients were randomly selected to four groups with a total burn surface area (TBSA) of 20-50%. The four groups includes olive oil (OO), flaxseed oil (FO), mixture of olive oil and flaxseed oil (OF), and control group and received 30g of oils for three weeks. Serum high-sensitivity C-reactive protein (hs-CRP), ferritin and albumin level as inflammatory markers, as well as cholesterol, triglyceride, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) as the lipid profile were explored. Wound healing was assessed by photographing on days 2, 8, 15, and 22 (during three weeks of intervention) and were analyzed in imageJ software. Results: The greatest reduction in the level of hs-CRP and ferritin was observed in the OF (-21.38±44.41) (-132.79±165.36), while the lowest reduction was reported in the control group (-36.36±79.03) (141.08±262.36). Compared to control group, OO significantly increased albumin (0.88±0.65). Reduction of wound healing at the end of the first week of intervention was not significant in the study groups. However, the stereology examination showed significant improvement in wound healing at the end of the second and third weeks in the OF. Conclusion: Based on the findings, combination of herbal oils reduce inflammation and improve wound healing and showed positive effects on the size of wounds in burn patients.

Hospitals' Food Services Quality and Factors Associated with Patients' Satisfaction in University Hospitals in the North of Iran.

This cross-sectional study evaluated patients' satisfaction with hospital meals in seven urban public hospitals using a validated questionnaire. The quality of food services based on the hospital standards was assessed using a checklist prepared by Iran's ministry of health. Of 800 subjects, the quality and quantity aspects of hospital meals, in general, were nearly satisfactory to the patients (mean score: 2.13, range: 1-3, SD: 0.39, 40% good and 36% moderate). The mean score of hospitals' food service quality based on hospital standards was 2.17 (range: 0-4, SD: 0.59). Females, younger patients and those with higher education level reported to be less pleased with hospital meal services. No relationship between patients' satisfaction and hospital food quality assessment based on hospital standards was found.

Insulin resistance surrogate markers and risk of hyperuricemia among patients with and without coronary artery disease: a cross-sectional study.

Background: Although emerging evidence emphasizes the associations between both insulin resistance and hyperuricemia with coronary artery disease (CAD) risk, no definite relationship has yet been established. In this respect, time-efficient and affordable methods to estimate insulin resistance (IR) status, and to predict risk of hyperuricemia, are needed. Thus, the goal of this investigation was to examine the associations between IR, as assessed by novel surrogate markers [triglyceride-glucose (TyG) and TyG-body mass index (TyG-BMI)], and risk of hyperuricemia in patients with and without diagnosed CAD. Methods: This cross-sectional study used data from the medical records of 1,170 patients who were referred to the cardiology outpatient clinic. Medical records, anthropometrics, and serum analytes were determined at the initial visit. Hyperuricemia was defined as serum uric acid ≥ 5.6 mg/dL. IR was estimated through surrogate markers (TyG and TyG-BMI). Multiple regression analysis was performed to assess the relationship between these indices and odds of hyperuricemia among patients with and without CAD. Results: Overall, 814 angiographically-confirmed CAD cases (mean age (SD) = 52 (8)yrs) were compared with 356 patients without CAD (mean age (SD) = 48 (8)yr). There were positive associations between TyG and TyG-BMI indices and odds of hyperuricemia in CAD patients after controlling for confounders (adjusted odds ratio (aOR) = 1.60; 95%CI: 1.02-2.51; p-value = 0.036; and aOR = 1.83; 95%CI: 1.24-2.70; p-value = 0.002, third tertiles for TYG and TYG-BMI, respectively). Conclusion: The present findings suggest that higher levels of the IR surrogate markers, TyG and TyG-BMI, are associated with higher odds of hyperuricemia in patients with CAD. However, given the cross-sectional design of this study, the sensitivity and specificity of these novel markers could not be determined for confirming the diagnosis of IR and hyperuricemia, further studies are needed to determine such outcomes and to confirm the current findings.

The effect of probiotic and synbiotic supplementation on lipid parameters among patients with cardiometabolic risk factors: a systematic review and meta-analysis of clinical trials.

Although the available evidence emphasizes the beneficial effects of probiotics in normalizing various cardiometabolic markers, there is still substantial uncertainty in this regard. Thus, we set out to determine the effect sizes of probiotics on blood lipid parameters more coherently. A systematic literature search of the Medline (PubMed) and Scopus databases was conducted from inception to 12 February 2021, applying both MeSH terms and free text terms to find the relevant randomized controlled trials (RCTs). The meta-analysis was conducted based on a random-effect model to calculate the mean effect sizes demonstrated as weighted mean differences (WMDs) and the 95% confidence intervals (95% CIs). To explore the heterogeneity, the Cochrane χ2 test, and analysis of Galbraith plots were performed. Meta-analysis of data from 40 RCTs (n = 2795) indicated a significant decrease in serum/plasma triglyceride [WMD (95% CI) = -12.26 (-17.11 to -7.41) mg/dL; P-value <0.001; I2 (%) = 29.9; P heterogeneity = 0.034], total cholesterol (with high heterogeneity) (WMD (95% CI) = -8.43 (-11.90 to -4.95) mg/dL; P-value <0.001; I2 (%) = 56.8; P heterogeneity < 0.001), LDL-C [WMD (95% CI) = -5.08 (-7.61, -2.56) mg/dL; P-value <0.001; I2 (%) = 42.7; P heterogeneity = 0.002], and HDL-C (with high heterogeneity) (WMD (95% CI) = 1.14 (0.23, 2.05) mg/dL; P-value = 0.014; I2 (%) = 59.8; P heterogeneity < 0.001) following receiving probiotic/synbiotic supplements. Collectively, the current preliminary evidence supports the effectiveness of probiotics/synbiotics in improving dyslipidaemia and various lipid parameters more prominently among subjects with hyperlipidaemia, diabetes, and metabolic syndrome. However, large and well conducted RCTs are required to provide further convincing support for these results.

The Prevalence of Non-Alcoholic Fatty Liver Disease in Iranian Children and Adult Population: A Systematic Review and Meta-Analysis.

Background: Non-alcoholic fatty liver disease (NAFLD) is the world's most common etiology of chronic liver disease. In this systematic review and meta-analysis, we estimated the prevalence of NAFLD in the Iranian children and adult population. Methods: A comprehensive search of five international databases, including PubMed, ISI/WOS, ProQuest, Scopus, and Google Scholar, was done from inception to Nov 2022. Studies on NAFLD patients and their risk factors were selected for meta-analysis. The quality of the included studies was assessed by The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for cross-sectional, and cohort studies. The heterogeneity between studies was investigated using Cochran test and I2 statistics. Random and fixed effect models were used for heterogenic and non-heterogenic studies, respectively. We used Comprehensive Meta-Analysis version 3 for conducting meta-analysis. Results: Twenty studies were finally included. The total prevalence of NAFLD in children, boys, and girls was 6.7% (95% CI: 0.02-0.18), 12.5% (95% CI: 0.04-0.29) and, 10.1% (95% CI: 0.04-0.21), respectively. The total prevalence of NAFLD in obese children, obese boys, and obese girls was 42% (95% CI: 0.18-0.69), 44% (95% CI: 0.13-0.80), and 33 % (95% CI: 0.13-0.62), respectively. The total prevalence of NAFLD in adults was 36.9% (95% CI: 0.31-0.42). The prevalence of NAFLD in men and women was 33.8% (95% CI: 0.27-0.41) and 29.9% (95% CI: 0.21-0.40), respectively. Conclusion: NAFLD prevalence in Iranian adults and obese children is considerable; however, data about the children population was insufficient.

Major Dietary Patterns in Association with the Grades of Nonalcoholic Fatty Liver Disease in Newly Diagnosed Patients Living in North of Iran.

Background: Evidence suggests that dietary pattern is related to incidence and grades of nonalcoholic fatty liver disease (NAFLD). The aim of this study was to investigate the relationship between major dietary patterns and hepatic histologic features of newly diagnosed patients with NAFLD. Methods: This cross-sectional study included 260 newly diagnosed NAFLD patients. Hepatic fibrosis and steatosis were diagnosed using Fibroscan. Dietary information was obtained using a validated 168-item semiquantitative food frequency questionnaire. The association between dietary patterns and odds ratio of the grade of fibrosis and steatosis was examined by multinomial logistic regression. Results: The mean ± SD age participant was 46.53 ± 11.71 years. Fifty-seven percent of the participants were women. Two major dietary patterns were recognized: "Western dietary pattern" and "Mediterranean dietary pattern." After adjustment for various confounders, adherence to the two extracted dietary patterns was not associated with odds of fibrosis and steatosis (P > 0.05). However, P was not significant. Patients in the second quartile of the Mediterranean dietary pattern had a higher risk for being in the F1 grade compared to those in the reference group in the crude and adjusted model. Conclusions: The major dietary patterns of NAFLD patients living in Gilan were not related to the severity of their disease. More precise study design such as cohort or interventional studies is suggested to reveal the strength of this study findings.

Inflammatory Markers and Atherogenic Coefficient: Early Markers of Metabolic Syndrome.

Background: Considering the close link between metabolic syndrome (MetSyn) and cardiovascular diseases, considerable attention has been devoted to the identification of their shared underlying pathological mechanisms in recent decades. Objectives: This study aimed to investigate the association between pro-inflammatory factors and newly-diagnosed MetSyn. Methods: This case-control study recruited obese and nonobese individuals who were newly diagnosed with MetSyn (cases, n = 84) and healthy individuals (controls, n = 83). The medical and sociodemographic data of the participants were collected on enrollment. Serum analysis was performed to ascertain the concentrations of tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), fasting blood sugar (FBS), total cholesterol, triglyceride, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and atherogenic coefficient (AC). Multiple regression analysis was carried out to explore the relationship between inflammatory markers and AC with MetSyn odds. The Pearson correlation test was also performed to investigate the correlations between metabolic and inflammatory parameters. Results: Positive relationships were observed between the serum levels of TNF-α and CRP with the odds of MetSyn following controlling for confounders (adjusted odds ratio [AOR] = 1.32; 95% confidence interval [CI]: 1.01 - 1.72; AOR = 1.29; 95% CI: 1.18 - 1.41; respectively, P ≤ 0.03). Additionally, higher AC was accompanied by increased odds of MetSyn (AOR = 1.98; 95% CI: 1.31 - 2.98; P = 0.001). The Pearson correlation analysis also showed positive correlations between TNF-α levels and serum metabolic abnormalities, including elevated LDL-C, FBS, and AC and lowered HDL-C levels (P ≤ 0.02). Conclusions: The present results revealed that higher serum concentrations of pro-inflammatory and atherogenic indices, including CRP, TNF-α, and AC, might be associated with elevated odds of newly diagnosed MetSyn regardless of potential confounders, particularly body mass index. The obtained findings might be moderated by the positive correlations observed between serum TNF-α, as the chronic inflammatory state indicator, and impaired lipid and glycemic markers.
