The Association Between Dietary Acidity and Clinical Symptoms in Patients With Rheumatoid Arthritis.

This study aimed to investigate the relationship between dietary acidity load and clinical symptoms in the patients with rheumatoid arthritis (RA). This case-control study examined 55 patients with RA and 215 healthy individuals in a Ravansar non-communicable diseases (RaNCDs) cohort study, Iran. Participants' food intakes were assessed using a validated food frequency questionnaire. The dietary acidity was calculated using potential renal acid load (PRAL), net endogenous acid production (NEAP), and dietary acid load (DAL) scores. The patients with RA were identified based on the self-reporting, medications history, and the approval of the cohort center physician following patients' examination. The odds ratio (OR) of joint stiffness in fully adjusted model was greater in the upper median of dietary acidity than in the lower median (PRAL: odds ratio [OR], 1.18; 95% confidence interval [CI], 0.59-2.36), but there was no statistically significant difference. The OR of joint pain in the upper median of dietary acidity was less than in the lower median in fully adjusted model (PRAL: OR, 0.70; 95% CI, 0.46-1.29), but the difference was not statistically significant. After adjusting potential confounders, people in the upper median of dietary acidity had a higher OR of developing RA than those in the lower median (PRAL: OR, 1.39; 95% CI, 0.70-2.76); however, it was not statistically significant. There was not any statistically significant relationship among dietary acidity and the odds of joint pain, joint stiffness, and developing RA.

The relationship between major dietary patterns and disease activity of rheumatoid arthritis.

AIM: Rheumatoid arthritis is an inflammatory illness characterized by persistent and systemic inflammation. There is just a little amount of research on nutrition and RA progression. The goal of this research is to see whether there's a link between main eating trends and RA activity. METHODS: In Kermanshah, Iran, 183 individuals with RA were studied in cross-sectional research. The American College of Rheumatology's 2010 criteria were used to diagnose RA. The disease activity score 28 and nutritional information from a reliable 147-item food frequency questionnaire were used to assess RA activity. Factor analysis was used to extract dietary patterns. RESULTS: The researchers discovered three main eating trends, which they named. Individuals in the highest tertile of a high protein anti-inflammatory dietary pattern that emphasizes consumption of dairy products, red meats, white meats, vegetables oils, condiments, vegetables and fruits as well as low in salts and refined grain had lower DAS-28 scores than those in the first tertiles (T3 = 2.09 ± 0.14 vs. T1 = 3.75 ± 0.13; P-value = 0.001) after controlling for potential confounders. Patients in the top tertile of the low fiber dietary pattern had higher DAS-28 scores than those in the bottom tertile (T3 = 3.40 ± 0.15 vs. T1 = 2.95 ± 0.15; P-value = 0.036) than those in the bottom tertile. CONCLUSION: This research found an inverse connection between RA activity and adopting a high-protein anti-inflammatory dietary pattern. Furthermore, adopting a low-fiber dietary pattern may be linked to increased RA disease activity. To confirm such a relationship, further research is needed in the future.

Nutritional status of under six years old children in Kalar city, Kurdistan Region, Iraq.

INTRODUCTION: Nutritional problems in children cause major morbidity and mortality in the world. This study aimed to assess the nutritional status of under six years old children in Kalar city, Kurdistan Region, Iraq. METHODS: In this longitudinal study, data from 403 Iraqi Kurdish children aged 0-72 months and their mothers were extracted from Health Centre in Kalar city undertaken between 2013 and 2019. The children`s growth data were obtained at birth time, 6, 12, 24, and 72 months. Epi Info was used to classify the children of nutritional status by converting the anthropometric measurements into Z-scores. Data were analyzed using SPSS 25 software. RESULTS: The prevalence of overweight and obesity rose from birth to age 6 years old, from 19.6% and 7.4% to 52.2% and 30.5%, respectively. At 24 month, children had the highest rates of being overweight (56.1%) and obesity (34%). At 6 month, the highest prevalence of wasting exists (9.5%). At 6 month boys and girls had the highest frequency of stunting, 17.2% and 7.2% respectively. Considering the association of all characteristic variables and growth data at birth time, only mothers with academic education had children with significantly higher BMI for age compared to illiterate mothers after adjusting for all potential confounders (ß: 0.573, 95% CI: 0.105, 1.04, P: 0.017). CONCLUSION: The study suggests that some analysed factors that accounted for malnutrition in Kalar city's children are preventable. Therefore, to reduce the burden of malnutrition, community-based education and targeted nutritional interventions are required.

Dietary total antioxidant capacity and its association with renal function and kidney stones: Results of a RaNCD cohort study.

There is evidence to support the hypothesis that dietary antioxidants have shown protective effects against chronic kidney disease (CKD). The purpose of this study was to determine the association between the dietary total antioxidant capacity (DTAC), renal function, and development of CKD and kidney stones in Ravansar Non-Communicable Diseases (RaNCD) cohort study, Kermanshah, Iran. This cross-sectional study was conducted using the recruitment baseline data of the RaNCD cohort study on 9,777 individuals aged 35-65 years. Food frequency questionnaire (FFQ) was performed to assess diet. DTAC scores were calculated using the ferric reducing antioxidant power (FRAP) of selected foods. Renal function was assessed by the estimated glomerular filtration rate (eGFR), blood urea nitrogen, and serum creatinine concentration. Prevalent CKD was based on an eGFR less than <60 ml/min per 1.73 m2. Incidence of kidney stones was also assessed by self-reporting. Out of 9,777 participants, 1,747 subjects (eGFR: 18.50 ml/min per 1.73 m2; 95% confidence interval (CI): 17.72-19.30) had CKD. The mean DTAC score in this study was 0.24 ± 0.16 µmol TE/100 g (micromole of Trolox Equivalents). We showed a significant trend for eGFR across quartiles of DTAC, i.e., participants in the fourth quartile had a higher glomerular filtration rate (GFR) than those in the first one (DTAC Q4 vs Q1 = 82.20 versus 72.20 ml/min per 1.73 m2, p < .001). Another finding is that high DTAC scores were not associated with having kidney stones after adjusting for confounders. We revealed that higher DTAC scores have positive effects on the renal function. Interestingly, our findings showed that a high DTAC score had nonsignificant correlation with odds of kidney stones.

Examining Lifestyle Components in Hospitalized COVID-19 Patients, Iran 2021.

Background: COVID-19 pandemic is a serious health threating element throughout the world. One of the key elements to strengthen the body's immune system is to follow a healthy lifestyle to deal with health threating. The aim of this study was to evaluate the lifestyle components in COVID-19 patients. Methods: This descriptive-analytical study carried on hospitalized COVID-19 patients from October 22, 2020 to January 19, 2021. Demographic characteristics, physical activity, nutritional status, stress and anxiety, and substance abuse were assessed. A simple model and multiple logistic regression model were used. Results: About 32% were hospitalized in the intensive care unit (ICU). Healthy lifestyle was observed only in 28%. About 82% had insufficient physical activity, and 67.3% was reported to be unfavorable in nutritional status. Severe stress and anxiety were observed in 30.4% of people. There were significant relationships between age (AOR = 2.11, p = 0.036), education (AOR = 0.35, p = 0.002) and a healthy lifestyle. A significant correlation was observed between ICU admission and unhealthy lifestyle (AOR = 0.40, p = 0.015). Conclusion: Unhealthy lifestyle behaviors were seen in the most COVID-19 patients. Considering the significance of lifestyle changes could prove effective in reducing the risk of transmissible viral infections.

The relationship of dietary total antioxidant capacity with sarcopenia and cardiometabolic biomarkers in type 2 diabetes patients.

BACKGROUND: The aim of this study was to investigate the relationship of dietary total antioxidant capacity (DTAC) with sarcopenia and metabolic biomarkers in people with type 2 diabetes in the Kurdish race. METHODS: In this cross-sectional study, data of 189 type 2 diabetic patients (35-65 years old) from RaNCD cohort study were evaluated. DTAC, fasting blood sugar, lipid profile, body composition, muscle strength, and sarcopenia were assessed. t and χ2 tests to compare the variables between sarcopenic and non-sarcopenic patients and one-way analysis of variance to compare the variables in DTAC tertiles were used. The relationship between DTAC and different variables was evaluated using multiple logistic regression model. RESULTS: The mean age and body mass index were 49.7 ± 8.7 years and 27.1 ± 3.9 kg/m2 . Body mass index, waist circumference, and hip circumference were significantly different between diabetic patients with and without sarcopenia (p < 0.05). In crude (p = 0.010) and adjusted (p = 0.035) models, there was a significant relationship between DTAC and fasting blood sugar. Also, the relationship between DTAC with waist (p = 0.019) and hip (ß = -4.25, p = 0.026) circumference was significant. Sarcopenia was significantly lower in the third tertile in comparison with the first tertile of DTAC (p = 0.016).  CONCLUSION: Diet with higher DTAC can be associated with lower fasting blood sugar, abdominal obesity and sarcopenia in type 2 diabetic patients. However, further studies are required to confirm these relationships.

The effects of co-administration of probiotics and prebiotics on chronic inflammation, and depression symptoms in patients with coronary artery diseases: a randomized clinical trial.

BACKGROUND: It has been shown that dysbiosis might have a role in developing of chronic inflammation and depression. In this study, we are interested in exploring of anti-inflammatory and anti-depressant effects of Lactobacillus Rhamnosus G (LGG), a probiotic strain, alone or in combination with a prebiotic, Inulin, in patients with coronary artery disease (CAD). METHODS: This randomized, double-blind clinical trial was held on 96 patients with CAD. Patients were randomly allocated into four different groups: LGG [a capsule/day, contained 1.9 × 109 colony-forming unit of Lactobacillus Rhamnosus G], inulin (15 g/day), co-supplemented (LGG and inulin), and placebo. Participants consumed the supplements for two months. Beck Depression Inventory (BDI), MacNew questionnaire and Spielberger state-trait anxiety inventory (STAI-Y) were used to assess depression, quality of life and anxiety, respectively. Serum levels of C-reactive protein (hs-CRP), lipopolysaccharide (LPS), tumor necrosis factor (TNF)-α, and Interleukin (IL)-10 were also measured. RESULTS: Probiotic-Inulin Co-supplementation significantly decreased BDI (-11.52 ± 0+3.20 vs. +2.97 ± 0.39, P = 0.001), STAI-state (-17.63 ± 3.22 vs. -0.60 ± 0.33, P = 0.021), and STAI-trait (-24.31 ± 7.41 vs. -1.45 ± 0.66, P = 0.020) scores, hs-CRP (-1.69 ± 0+66 vs. +0.82 ± 0.39 mg/dL, P = 0.020), LPS (-22.02 ± 5.40 vs. +0.31 ± 0.18 (EU/L), P = 0.047), and TNF-α (-25.05 ± 7.41 vs. +0.79 ± 0.71 (ng/L), P = 0.032) in comparison to placebo. CONCLUSION: Co-supplementation of probiotics and inulin in CAD subjects for eight weeks had beneficial effects on depression, anxiety, and inflammatory biomarkers. Adding inulin to probiotic supplements improved psychological outcomes and inflammatory biomarkers more effectively than two supplements separately.Trial registration: Iranian Registry of Clinical Trials identifier: IRCT20180712040438N4..

The Association of Dietary Total Antioxidant Capacity with Inflammatory Biomarkers and Anthropometric Indices in Patients Who Candidate for Coronary Artery Bypass Graft Surgery: a Cross-sectional Study.

Antioxidant compounds can attenuate inflammation and delay degenerative processes especially in the cardiovascular system. This study aimed to determine the relationship between dietary total antioxidant capacity (DTAC) and serum biomarkers in patients undergoing coronary artery bypass graft surgery. In this cross-sectional study, 146 patients who had referred to Imam Ali Hospital in Kermanshah were recruited and demographic, anthropometric, physical activity and dietary data were collected. Fasting blood glucose (FBG), serum levels of lipid profile, inflammatory markers (interleukin [IL]-17, intercellular and vascular cell adhesion molecules [ICAM, VCAM]), and total antioxidant capacity (TAC) were also measured. A regression model adjusted for confounding variables presented that the coefficients of ICAM and VCAM (ng/dL) in the third tertile of DTAC were lower than those in the first tertile (ß = -417.2, 95% confidence interval [CI] = -509.9 to -324.5, p < 0.001; ß = -293.2, 95% CI = -334.3, -252.1, p < 0.001, respectively). The ß of serum TAC (ng/dL) in the third tertile was 0.86 (95% CI = 0.77, 0.95, p < 0.001) higher than that in the first tertile. DTAC had no statistically significant relationship with lipid profile, FBG, and IL-17 levels, and anthropometric indices. In this study DTAC was associated with increased serum TAC and decreased cell adhesion molecules. Therefore, diet antioxidants may be beneficial in attenuating of inflammation in coronary artery diseases.

Effects of body weight regain on leptin levels: A systematic review and meta-analysis.

BACKGROUND: There are different changes observed before and after diet therapy, and also after weight regain. However, there is not sufficient information regarding weight regain and hormonal changes. PURPOSE: The purpose of this study was to review the connection between weight regain and leptin concentration levels. METHODS: MEDLINE, SCOPUS, Web of Science, and the Cochrane Library were searched for interventional articles published from January 1, 1980, to June 30, 2020. Randomized clinical trials with parallel or cross over design assessing leptin concentrations at the baseline and at the end of study were reviewed. Two independent reviewers extracted data related to study design, year of publication, country, age, gender, body mass index (BMI), duration of the following up period and mean ± SD of other intended variables. RESULTS: Four articles were included, published between 2004 and 2016. Three of them were conducted in the US and one of them in Netherland. Sample size of the studies ranged between 25 and 148 participants. The range of following up period was from13 to 48 weeks. The age range of participants was from 34 to 44 years. Our analysis shows that weight regain could reduce leptin levels, but this change is not statistically significant. CONCLUSION: This review suggests that weight regain may induce a non-significant reduction in leptin level. However, the limited number and great heterogeneity between the included studies may affect the presented results and there are still need to well-designed, large population studies to determine the relationship between weight regain and leptin levels.

Circulating Advanced Glycation End Products and Their Soluble Receptors in Relation to All-Cause and Cardiovascular Mortality: A Systematic Review and Meta-analysis of Prospective Observational Studies.

Advanced glycation end products (AGEs) are involved in the development of several age-related complications. The protective role of soluble receptors for AGEs (sRAGE) against deleterious effects of AGEs has been indicated in several studies. However, findings on the association of AGEs or sRAGE with mortality are equivocal. In this meta-analysis we aimed to present a quantitative estimation of the association between circulating AGEs or sRAGE and all-cause or cardiovascular disease (CVD) mortality. A comprehensive literature search was performed to determine relevant publications through the online databases including PubMed, Scopus, and Web of Science up to 29 November 2020. Prospective observational studies assessing the association between circulating AGEs or sRAGE and all-cause or CVD mortality were included. Seven studies with a total of 3718 participants and 733 mortality cases (345 CVD deaths) were included in the meta-analysis for assessing the association between circulating AGEs and mortality. Our results showed that higher circulating AGEs were associated with increased risk of all-cause (pooled effect measure: 1.05; 95% CI: 1.01, 1.09; P = 0.018, I2 = 77.7%) and CVD mortality (pooled effect measure: 1.08; 95% CI: 1.01, 1.14; P = 0.015, I2 = 80.2%), respectively. The association between sRAGE and mortality was assessed in 14 studies with a total of 16,335 participants and 2844 mortality cases (419 CVD deaths). Serum concentrations of sRAGE were not associated with the risk of all-cause mortality (pooled effect measure: 1.01; 95% CI: 1.00, 1.01; P = 0.205, I2 = 75.5%), whereas there was a significant link between sRAGE and the risk of CVD mortality (pooled effect measure: 1.02; 95% CI: 1.00, 1.04; P = 0.02, I2 = 78.9%). Our findings showed that a higher serum AGE concentration was associated with increased risk of all-cause and CVD mortality. In addition, higher circulating sRAGE was related to increased risk of CVD mortality. This review was registered at PROSPERO as CRD42021236559.

Cost-effectiveness analysis of lung cancer screening with low-dose computed tomography in an Iranian high-risk population.

OBJECTIVE: The results of recent studies have shown that using low-dose computed tomography (LDCT) for screening of lung cancer (LC) improves cancer outcomes. The objective of the current study was to evaluate the cost-effectiveness of LDCT in an Iranian high-risk population. METHODS: A Markov cohort simulation model with four health states was used to evaluate the cost-effectiveness of LDCT from a healthcare system perspective in the people aged 55-74 who smoked 25 or more cigarettes per day for 10-30 years. Cost data were collected, reviewing 324 medical records of patients with LC, and utilities and transition probabilities were extracted from the literature. The Monte Carlo simulation method was applied to run the model. Probabilistic sensitivity analysis and one-way analysis were also performed. RESULTS: LC screening in comparison to a no-screening strategy was costly and effective. The incremental cost-effectiveness ratio of screening versus no-screening was IRR (Iranian rials) 98,515,014.04 which falls below the Iranian threshold of three times GDP (gross domestic product) per capita. One-way and probabilistic sensitivity analyses demonstrated that the results of the economic analysis were robust to variations in the key inputs for both. CONCLUSIONS: Using LDCT for screening of LC patients in a high-risk population is a cost-effective strategy.

Effects of alpha lipoic acid on iron overload, lipid profile and oxidative stress indices in ß-thalassemia major patients: A cross-over randomised controlled clinical trial.

AIMS: ß-Thalassemia major (ß-TM) is associated with iron overload, abnormal lipid levels and oxidative stress. Alpha lipoic acid (ALA) showed anti-oxidant and iron chelating properties, but its effect in ß-TM patients is unclear. We investigated the effects of ALA on iron levels, lipid profile and oxidative stress. METHODS: In this cross-over randomised clinical trial, 26 ß-TM patients were assigned to receive 600 mg/d ALA or placebo (corn starch), for 8 weeks with a 21-days washout period. Serum ferritin, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), LDL-C/HDL-C, total antioxidant capacity, malondialdehyde (MDA) and MDA/LDL-C were assessed at baseline and the end of each intervention phase. RESULTS: Twenty-two patients completed the study. Serum ferritin (P = .004), MDA (P = .025) and MDA/LDL-C ratio (P =.002) were decreased and HDL-C (P =.035) increased significantly during ALA consumption. In comparison with placebo, ALA decreased the serum ferritin significantly (P = .02). Also, the changes in serum ferritin between ALA and placebo (-123.1 ± 40.0 vs -34.3 ± 21.0, P =.03) was significant in women subgroup. ALA had no significant effects on the other biomarkers. CONCLUSION: The results of this study indicated that supplementation with 600 mg/d ALA may decrease serum ferritin in ß-TM. Further studies are needed to confirm the findings.

Probiotic Yogurt Fortified with Vitamin D Can Improve Glycemic Status in Non-Alcoholic Fatty Liver Disease Patients: a Randomized Clinical Trial.

Non-alcoholic fatty liver disease (NAFLD) is a significant public health problem globally and the most notable chronic liver disease in Asian countries. Various dietary supplements have been assessed as potential methods to alleviate the metabolic damages related to NAFLD, but the results of these works have been equivocal. This study aimed to evaluate the effects of probiotic yogurt fortified with vitamin D (Pro-YFD) on glycemic and anthropometric indices in patients with NAFLD. One hundred and four NAFLD patients of both sexes were randomly allocated to 2 groups: group A (Pro-YFD) and group B (unfortified yogurt). The intervention period was 3 months. Fasting blood samples were obtained for measuring fasting blood sugar (FBS) and insulin level. Food intake was measured using a validated food frequency questionnaire. Body composition was estimated by bio-impedance. Eighty-eight patients completed the study. The mean serum level of 25(OH)D3 was elevated significantly (p < 0.001), while insulin level decreased significantly (p < 0.003) in group A at the end of the study. FBS levels showed no significant differences between the groups at the end of the trial. Also, there were no significant changes in diet caloric intake, physical activity, or anthropometric indices in the 2 groups during the interventions. Pro-YFD in the diets of patients with NAFLD may attenuate insulin resistance and improve serum level of 25(OH)D3.

The effect of green tea on prostate specific antigen (PSA): A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Prostate cancer is a major malignancy, affecting men, worldwide. The protective effect of green tea consumption on prostate cancer has been reported in several studies; however, the findings are equivocal. OBJECTIVE: The aim of this study was to evaluate the effects of green tea on PSA level, by conducting a systematic review and meta-analysis of randomized controlled trials. METHODS: We searched online databases, including PubMed, Scopus, and Web of Science, up to 11 Aug 2020, to obtain relevant publications. The publication search was not limited by language or date. RESULTS: A total of 2488 records were identified in the systematic search; from these, seven were included in the meta-analysis. The overall analysis showed no significant changes in PSA levels in subjects treated with green tea, (WMD: ‒0.60 ng/mL; 95 % CI: ‒1.32, 0.12 ng/mL; P = 0.104, I2 = 93.80 %, P heterogeneity<0.001). Subgroup analysis based on geographical location showed that green tea significantly reduced PSA level in the USA population (WMD: ‒1.02 pg/mL, 95 % CI: ‒1.30, ‒0.73, P < 0.001) compared to non-USA populations (WMD: ‒0.22 pg/mL, 95 % CI: ‒0.95, 0.50, P = 0.539) (P < 0.001). CONCLUSION: The results of this review show that green tea has no significant effect on PSA level. However, due to the heterogeneity among studies more consistent clinical trials, with larger sample sizes are required.

Cost-Effectiveness Analysis of Colorectal Cancer Screening: A Systematic Review.

INTRODUCTION: Colorectal cancer (CRC) is a significant health problem with an increasing incidence worldwide. Screening is one of the ways, in which cases and deaths of CRC can be prevented. The objective of this systematic review was to evaluate the cost-effectiveness of the different CRC screening techniques and to specify the efficient technique from a cost-effectiveness perspective. METHODS: The economic studies of CRC screening in general populations (average risk), aged 50 years and above were reviewed. Two reviewers independently reviewed the titles, abstracts, and full-texts of the studies in five databases: Cochrane, Embase, Scopus, Web of Science and PubMed. The disagreements between reviewers were resolved through the authors' consensus. The main outcome measures in this systematic review were the incremental cost-effectiveness ratio (ICER) of screening versus no-screening and then in comparison with other screening techniques. The ICER is defined by the difference in cost between two possible interventions, divided by the difference in their effect. RESULTS: Eight studies were identified and retained for the final analysis. In this study, when screening techniques were compared to no-screening, all CRC screening techniques showed to be cost-effective. The lowest ICER calculated was $PPP -16265/quality-adjusted life-year (QALY) (the negative ICERs were between purchasing power parity in US dollar ($PPP) -16265/QALY to $PPP -1988/QALY, whereas the positive ICERs were between $PPP 1257/QALY to $PPP 55987/QALY). For studies comparing various screening techniques, there was great heterogeneity in terms of the structures of the analyses, leading to diverse conclusions about their incremental cost-effectiveness. CONCLUSION: All CRC screening techniques were cost-effective, compared with the no-screening methods. The cost-effectiveness of the various screening techniques mainly was dependent on the context-specific parameters and highly affected by the framework of the cost-effectiveness analysis. In order to make the studies comparable, it is important to adopt a reference-based methodology for economic evaluation studies.

Effects of vitamin D supplementation on core symptoms, serum serotonin, and interleukin-6 in children with autism spectrum disorders: A randomized clinical trial.

OBJECTIVES: Children with autism spectrum disorders (ASD) have lower serum vitamin D and higher serotonin and interleukin (IL)-6 levels compared with healthy children. The aim of this study was to evaluate the effect of vitamin D on core symptoms and serum levels of serotonin and IL-6 in these children. METHODS: This parallel randomized double-blind, placebo-controlled trial was conducted with 43 children with ASD (7 girls and 36 boys; 8.91 ± 2.87 y of age). Children were randomly allocated to receive either vitamin D drop (300 IU/kg up to a maximum of 6000 IU daily) or placebo for 15 wk. Serum levels of 25-hydroxyvitamin (OH)D, IL-6, and serotonin were measured at baseline and at the end of the trial. Also, the severity of autism and the social and individual maturity of the children were measured by the Childhood Autism Rating Scale (CARS), the Autism Treatment Assessment Checklist (ATEC), and Aberrant Behavior Checklist-Community (ABC-C) questionnaires before and after intervention. Randomization and allocation to groups were done using computer-generated numbers. RESULTS: More than 86% of patients had vitamin D deficiency at the beginning of the study. Serum levels of 25(OH)D increased significantly in the vitamin D group (P = 0.001). The clinical symptoms of autism measured by CARS and ATEC scales were alleviated significantly (P = 0.021 and P = 0.020, respectively); however, the serum levels of serotonin and IL-6 and the scale of ABC-C remained without a significant change. CONCLUSION: These findings suggest that vitamin D supplementation may improve ASD symptoms; however, more studies with longer duration are indispensable to confirm our results.

Effects of Alpha-Lipoic Acid Supplementation on Cardiovascular Disease Risk Factors in ß-Thalassemia Major Patients: A Clinical Trial Crossover Study.

AIM: Thalassemia is one of the most common genetic diseases, and cardiovascular disease (CVD) has been considered as the leading cause of mortality in more than 50% of ß-thalassemia patients. The aim of this study was to determine the effects of alpha-lipoic acid (ALA) on CVD risk factors in ß-thalassemia major patients. METHODS: Twenty ß-thalassemia major patients participated in this randomized crossover clinical trial study. Participants were randomly assigned to ALA (600 mg/day) or placebo groups for two 8-wk interventions that were separated by a 3-wk washout period. The CVD risk factors including serum osteoprotegerin (OPG), homocysteine, lipoprotein-associated phospholipase A2 and trimethylamine N-oxide were measured at the beginning and the end of each intervention phase according to the standard protocol. RESULTS: Serum OPG reduced significantly in the ALA group in all participants (5.38 ± 2.79 to 3.27 ± 2.43 ng/mL, P= .003) and in the male subgroup (5.24 ± 2.56 to 3.13 ± 2.5 ng/mL, P= .015); this reduction was significant in comparison with the placebo group (P= .013). The changes in other CVD risk factors were not significant. CONCLUSION: The results of this study showed that after 8-wk of ALA consumption, the serum OPG reduced significantly in ß-thalassemia major patients. Therefore, controlling the serum OPG level with ALA consumption can be an important complementary therapeutic option to prevent the progression of CVD in ß-thalassemia major patients.

Relationship Between the Consumption of Milk-Based Oils Including Butter and Kermanshah Ghee with Metabolic Syndrome: Ravansar Non-Communicable Disease Cohort Study.

BACKGROUND: The prevalence of metabolic syndrome (MetS) in recent years has been growing in different societies, which may be due to lifestyle changes including changes in diet, in particular the consumption pattern of edible oils. The purpose of this study was to investigate the relationship between the consumption of animal oils including butter and Kermanshah ghee with MetS and its components in the adult population of Ravansar Non-Communicable Disease (RaNCD) cohort study. METHODS: This cross-sectional study was carried out on 5550 adults aged 35-65 years using baseline data of Ravansar's prospective study center in Iran. MetS was defined according to the criteria of modified NCEP ATP III for Iranian adults. Relationship between the consumption of butter and Kermanshah ghee and MetS was analyzed by logistic regression model using STATA software. RESULTS: In our study, the frequency of MetS was 31.40%. The mean body mass index and mean age were 27.1±4.6 kg/m2 and 47.6±8.2 years. The mean values of consumed butter and Kermanshah ghee were 3.3±1.8 and 5.1±2.3 g/day, respectively. After adjusting the confounding variables, the highest to the lowest quintile of butter and Kermanshah ghee consumption showed a reverse correlation with the MetS (OR = 0.7, 95% CI = 0.5-0.9) and (OR= 0.7, 95% CI=0.6-0.9), respectively. CONCLUSION: This study revealed a reverse relationship between milk and Kermanshah ghee consumption with MetS and its components. Therefore, consumption of milk-based oils may be associated with lower cardiovascular risk factors.

Antihyperlipidemic and Antioxidative Properties of Pistacia atlantica subsp. kurdica in Streptozotocin-Induced Diabetic Mice.

INTRODUCTION: Pistacia atlantica subsp. kurdica is an important food source and a well-known medicinal plant in the Zagros Mountains of Iran. The present study aimed to investigate the effect of P. atlantica extract and essential oil in streptozotocin-induced diabetic mice. MATERIALS AND METHODS: Different doses of hydroalcoholic extract and essential oil of P. atlantica subsp. kurdica (50, 100, and 200 mg/kg) were given to streptozotocin-induced diabetic mice in separate groups for three weeks. At the end of treatment, blood samples were collected; then, oxidative stress markers, TNF-α, and lipid profile were determined in its serum samples. RESULTS: Our findings showed that the administration of P. atlantica extract for three consecutive weeks significantly improved the lipid profile, oxidative stress, and inflammation process by reducing lipid peroxidation and increasing total antioxidant capacity. CONCLUSION: This study showed that P. atlantica subsp. kurdica has antioxidant and blood lipid-lowering effects that can be used as a supplement to improve diabetes complications.

Effects of Chromium Picolinate Supplementation on Cardiometabolic Biomarkers in Patients with Type 2 Diabetes Mellitus: a Randomized Clinical Trial.

Type 2 diabetes mellitus (T2DM) is a serious public health problem accompanies with several complications. This study was conducted to evaluate the effects of chromium picolinate (CrPic) supplementation on the glycemic status and lipid profile in patients with T2DM. The patients with T2DM (n = 52) were randomly allocated into 2 groups. One group received 400 µg CrPic per day and the other group took placebo; the intervention duration was 8 weeks. Anthropometric indices and metabolic factors were measured at the beginning, and at end of the study. The patients were recommended not to change their normal diet, life style and medication. No significant changes were observed for weight, body mass index, and fasting blood glucose (FBG) in both groups; while intra-groups changes in homeostatic model assessment for insulin resistance (HOMA-IR) value was significant (p < 0.05). Results of analysis of covariance showed that there were significance differences between groups in total cholesterol, low density lipoprotein cholesterol and HOMA-IR at the end of the intervention adjusting for baseline levels (p = 0.035, 0.030 and < 0.001, respectively). In this study, oral supplementation with 400 µg CrPic for eight weeks did not alter FBG concentration as well as anthropometric parameters in individuals with T2DM. However, the modest beneficial effects of chromium supplementation on insulin resistance as indicated by HOMA-IR and lipid profile were found.
