    Abstract Introduction Ramadan fasting is globally observed and a great majority of the residents of Islamic countries and elsewhere fast during Ramadan all across the world every year. Many patients with type 1 diabetes fast during Ramadan according to (or against) medical and jurisprudence advice. Nonetheless, there is a paucity of scientific evidence regarding the risks patients with diabetes who fast may be confronted with. The current scoping review protocol aims at systematic analysis and mapping of existing literature in the field and highlighting scientific gaps.Methods and analyses This scoping review will be conducted based on the Arksey and O'Malley’s methodological framework with consideration of later modifications and amendments. Three major scientific databases, namely PubMed, Scopus and Embase up to February 2022 will be systematically searched by expert researchers in collaboration with a medical librarian. Considering the fact that Ramadan Fasting is a cultural-dependent subject, which may be studied in the Middle Eastern and Islamic Countries in languages other than English, local Persian and Arabic Databases will also be included. Grey literature will be sought too, and unpublished works such as conference proceedings and academic degree dissertation will be considered. Subsequently, one author will screen and record all abstracts, and two reviewers will independently screen and retrieve eligible full texts. A third reviewer will then be designated to resolve potential discrepancies. Standardised data charts and forms will be used for information extraction and reporting of the outcomes.Ethics and dissemination No ethical considerations apply to this research. Results will be published and presented in academic journals and scientific events.

    Abstract Introduction: Considering an individual’s characteristics such as genetics along with other characteristics and dietary habits can help to provide an effective diet for prevention and controlling metabolic disorders. Accordingly, in the present study, we aimed to review evidence on personalized nutrition (PN) and its roles in metabolic disorders. Materials and Methods: In the present narrative review, publications on PN and metabolic disorders published between 2010 and 2020 using PubMed, Scopus, and Google Scholar were searched and collected. Results: Our findings showed positive effects of precision medicine and PN on controlling metabolic disorders, diabetes, postprandial glucose level, obesity, and lipid profile. Interactions of genetic differences, lifestyle, microbiota patterns, and behavioral and psychological characteristics can affect developing and controlling diseases. Conclusion: Due to the effects of genetics, gut microbiota, and other individual characteristics in designing and providing a suitable diet, paying attention to PN in the prevention and controlling metabolic disorders is important. PN vs. general dietary recommendations or diet can be more effective; although it needs high expenditure and more equipment.

    Abstract Objectives. Although several clinical trials have revealed the beneficial effects of honey on metabolic profiles, the results are conflicting. The aim of this study was to systematically summarize the effects of oral consumption of honey on key metabolic profiles in adult patients with type 2 diabetes mellitus (T2DM) and nondiabetic individuals. Methods. In total, four electronic databases, including PubMed/Medline, Web of Science, Scopus, and Cochrane library, were searched from 2000 to 31 July 2019 to identify all English language studies that would meet the eligibility criteria. Clinical trials which have examined the effects of oral consumption of any types of honey on anthropometric indices, glycemic status, lipid profiles, and blood pressure in both diabetic and nondiabetic adult subjects were included in the study. Results. Of the 7769 possible relevant studies (including 3547 duplicates) identified in the initial search, finally, 13 clinical trials were included in the systematic review. All studies except three had a parallel design. Of 13 studies, 8 trials did not have placebo/control groups. The included studies examined the impact of oral consumption of honey on glycemic status (n = 12), anthropometric indices (n = 6), lipid profiles (n = 10), and blood pressure (n = 3). Based on the Jadad scale, 5 studies had acceptable methodological quality, and the remaining (n = 8) had low methodological quality. Conclusion. The current systematic review showed that oral consumption of honey might have no significant effects on the modulation of metabolic profiles in nondiabetic subjects. In addition, a high intake of honey might increase glucose levels and worsen other metabolic parameters in patients with T2DM. Due to substantial heterogeneity in study design and limited clinical trials, results, however, should be interpreted with great caution.

    Abstract Abstract Background The prevalence of Type 2 Diabetes Mellitus (T2DM) in the North Africa and Middle East region is alarmingly high, prompting us to investigate the burden and factors contributing to it through the GBD study. Additionally, there is a lack of knowledge about the epidemiological status of T2DM in this region, so our aim is to provide a comprehensive overview of the burden of T2DM and its associated risk factors. Methods Using data from the 2019 Global Burden of Disease Study, we calculated the attributable burden of T2DM for each of the 21 countries in the region for the years 1990 and 2019. This included prevalence, mortality, disability-adjusted life years (DALYs), and risk factors. Results Between 1990 and 2019, there was a significant increase in the age-standardized incidence (79.6%; 95% Uncertainty Interval: 75.0 to 84.5) and prevalence (85.5%; [80.8 to 90.3]) rates of T2DM per 100,000 populations. The age-standardized mortality rate (1.7%; [-10.4 to 14.9]), DALYs (31.2%; [18.3 to 42.2]), and years lived with disability (YLDs) (82.6%; [77.2 to 88.1]) also increased during this period. Modifiable risk factors, such as high body mass index (56.4%; [42.8 to 69.8]), low physical activity (15.5%; [9.0 to 22.8]), and ambient particulate matter pollution (20.9%; [15.2 to 26.2]), were the main contributors to the number of deaths. Conclusion The burden of T2DM, in terms of mortality, DALYs, and YLDs, continues to rise in the region. The incidence rate of T2DM has increased in many areas. The burden of T2DM attributed to modifiable risk factors continues to grow in most countries. Targeting these modifiable risk factors could effectively reduce the growth and disease burden of T2DM in the region.

    Abstract Blood pressure is one of the vital signs, and is the pressure of circulating blood on the walls of blood vessels. When the large arteries lose their natural elasticity and strength, and the smaller ones are narrowed, blood pressure rises and the pressure is exerted by blood on the walls of blood vessels. High blood pressure is dangerous and very harmful for the heart and blood vessels, and is a major cause of mortality in all nations. Many patients tend to use herbal products for controlling their blood pressure, as they are concerned of the side effects of the chemical drugs. There are huge amount of research work exploring the safety and efficacy of a single herb, or combined herbal products on lowering blood pressure, among which some have shown certain effects, and some are negative in results. Grape seed, Garlic, Saffron, Green and White Mulberry, Quince, and some other herbs have more scientific evidence in lowering blood pressure. In this study, we systematically reviewed the scientific literature of clinical trials and animal studies, in which the safety and effectiveness of herbs on lowering blood pressure were evaluated.

    Abstract Purpose: Obesity is a multi-factorial health problem which results from the interaction of environmental and genetic factors. The aim of the present study was to determine the effects of dried licorice extract with a calorie restricted diet on anthropometric indices and insulin resistance with nutrigenetic approach. Methods: For this pilot, double-blind, placebo-controlled randomized clinical trial, 72 eligible subjects were randomly allocated to Licorice or placebo group. They received a low-calorie diet either with a 1.5 g/day of Licorice extract or placebo for 8 weeks. Results: There were no significant differences in anthropometric indices and dietary intake in genotype subgroups at the baseline. Findings indicated that supplementation with Licorice extract did not change anthropometric indices and biochemical parameters significantly compared to a hypocaloric diet alone. However, from the nutrigenetic point of view, significant changes in anthropometric indices and QUICKI were observed in the Pro12Pro genotypes compared to the Pro12Ala at the end of the study (p<0.05 in all variables). Moreover, no interactive effect of the Licorice supplement and Pro12Ala genotype was found. Conclusion: In obese subjects, the Pro/Pro polymorphism of the PPAR-γ2 gene seems to induce favourable effects on obesity management. Further studies are needed to clarify whether PPAR-γ2 gene polymorphisms or other obesity genes can affect responses to obesity treatment.

    Abstract Objective: Although some earlier studies have indicated an association between dietary/urinary sodium and bone mass density (BMD), bone mass content (BMC), and the risk of osteoporosis (OS), findings are still conflicting. The aim of this study was to summarize the relation of dietary/urinary sodium with BMD, BMC, and the risk of OS. Methods: We conducted a systematic search up to April 2017 in PubMed/MEDLINE, SCOPUS, and Web of Science to find relevant studies. Articles with cross-sectional and cohort designs in which odds ratios (ORs), correlations (r), or beta coefficients were reported for the association between dietary/urinary sodium and OS, BMD, or BMC were included. Results: Pooling 11 effect sizes with a total of 39,065 people showed that higher sodium consumption significantly increased the risk of OS (OR = 1.20; 95% confidence interval [CI], 1.02–1.41; p = 0.026), with high heterogeneity among studies (I2 = 68.0%; p = 0.001). Subgroup analyses showed significantly higher risk of OS in premenopausal women (OR = 1.31; 95% CI, 1.01–1.69; p = 0.036), in participants with a mean age older than 50 years (OR = 1.15; 95% CI, 1.04–1.28; p = 0.005), in dietary sodium intake subgroup (OR = 1.45; 95% CI, 1.19–1.77; p < 0.001), and in individuals with adjustment for energy (OR = 1.77; 95% CI, 1.38–2.27; p < 0.001). The correlation coefficients showed no significant association between urinary sodium and BMD (r = −0.46; 95% CI, −0.74 to −0.18; p = 0.02). Conclusions: We found a positive association between sodium intake and the risk of OS, while no association was found with urinary sodium. Furthermore, there was no significant correlation between sodium intake and BMD. Due to high heterogeneity in this research, more studies are suggested.

    Abstract Background: The prevalence of cardiovascular disease is dramatically increasing particularly in developing countries. Among the different factors, diet has an important role in the pathogenesis of these diseases. This study aimed to assess the relationship between dietary quality index-international (DQI-I) and cardiovascular risk factors in adult Iranian women. Methods: This was a cross-sectional study of 371 participants, aged 20-50 yr, and recruited from 10 health centers from health centers affiliated with Tehran University of Medical Sciences (TUMS), Tehran, Iran in 2018. Usual dietary intake was evaluated by a validated and reliable 168-items food frequency questionnaire (FFQ). To assess overall quality of diet, the Dietary Quality Index-International (DQI) was used. Anthropometric measurements, blood pressure, and fasting blood of samples were taken to assess biochemical parameters related to cardiovascular disease. Results: The results of linear regression showed that DQI-I score was inversely and directly associated with serum level of total cholesterol (TC) (0.27, confidence interval (CI): 0.13-0.58; P<0.001) and high-density lipoprotein cholesterol (HDL-C) (2.53, CI: 1.42-4.52; P=0.001), respectively. However, there was no significant association between DQI-I and other cardiovascular risk factors. Conclusion: A greater DQI-I score was associated with preferable lipid profile including TC and HDL-C. Future large-scale, prospective cohort or clinical studies are required to confirm these findings.

    Abstract Abstract Background Vitamin D deficiency (VDD) is recognized as a global pandemic. Identification, any association between VDD and subjective health complaints (SHC), can be helpful to realize critical mechanisms and improve psychological and somatic symptoms. Given few studies published on this issue and the importance of its clarification, the main objective of this study was to examine the association between VDD and the SHC in children and adolescents. Methods In this national cross-sectional study, 2596 Iranian children and adolescents aged 8–18 years were included. Data on SHC, anthropometric indices, physical activity, and serum levels of vitamin D were collected. Logistic regression models (crude, adjusted) were applied to examine the association between the VDD and the SHC. Statistical analysis was performed using STATA version 11. P-values< 0.05 were considered as statistically significant. Results Serum levels of vitamin D in approximately 70% of Iranian children and adolescents were lower than 30 ng/mL. Among the SHC, irritability (40.9%) and feeling anxiety (33.7%) were the most prevalent ones. Multiple complaints in students with the VDD was 2.5 times greater than those with sufficient vitamin D concentrations (p < 0.001). Compared to the reference group, the strongest association was found between vitamin D status and difficulties in getting to sleep (OR: 2.5, 95%CI: 1.18, 3.53, p < 0.001). Conclusion VDD was observed in the considerable percentage of the study population. There were no significant differences between the two gender groups. In addition, there were significant associations between vitamin D status and most of the somatic and psychological symptoms, particularly for getting to sleep. It seems national interventional programs for vitamin D supplementation or food fortifications can be helpful.

    Abstract Background: Traffic Light Labeling (TLL) system is a simple tool to communicate information regarding the nutrients content of food products and has been widely applied to promote public health. However, evidence on the effectiveness of the TLL system on consumers’ choices is conflicting. The present study aims to systematically summarize the effects of TLL on consumers’ point of purchase behaviors. Methods: Five electronic databases, including PubMed/Medline, Scopus, Web of knowledge, the Cochrane library, and Science direct were searched from 2000/01/01 to 2021/11/01. Randomized-controlled trials, in English or Farsi languages, investigating the effects of TLL on choosing healthier foodstuffs or beverages were examined for eligibility and included in the review. Of 6408 potentially relevant publications (including 1255 duplicates), five clinical trials were finally included in the study. Results: The duration of the interventions ranged from 4 to 12 weeks and all studies except one had high methodological quality. Out of 5, three clinical trials did not show positive effects of TLL on customers' choices to purchase healthier food products. Conclusions: The present review showed that TLL without other public health-promoting interventions may have no substantial effects on consumer’s food choice.
