Dyslipidemia is the main risk factor for developing cardiovascular disease. There are discrepancies in the effects of calcium supplementation on modulation of lipid status. Therefore, we aimed to summarize the effects of dietary calcium supplement on circulating lipoprotein concentrations and atherogenic indices in overweight and obese individuals. We conducted a systematic literature search from 2000 until July 2016. PubMed, Scopus, Cochran Library, and ISI Web of Science databases were searched for clinical trials written in English. Placebo controlled clinical trials on calcium or calcium with vitamin D supplement in overweight and obese indiciduals were considered. Finally, 11 clinical trials met the criteria and were included. Most studies (n = 9) evaluated Ca/D co-supplementation. Positive effects of calcium supplementation alone or with vitamin D were as follows: serum levels of total cholesterol (TC; n = 1), triglyceride (TG) concentrations (n = 1), serum levels of low-density lipoprotein cholesterol (LDL-C; n = 5) and high-density lipoprotein cholesterol (HDL-C; n = 3). Seven clinical trials reported atherogenic indices and three of them demonstrated beneficial effects of calcium supplementation on at least one atherogenic index. Calcium supplementation may not be helpful to reduce serum levels of TC and TG in overweight and obese individuals. However, it may modulate LDL-C and HDL-C concentration. More studies are warranted to clarify the effects of calcium supplementation on each atherogenic index. [ABSTRACT FROM AUTHOR]

Purpose: The aim of present study was to determine effects of L-Arginine supplementation on antioxidant status and body composition in obese patients with prediabetes. Methods: A double-blind randomized control trial was performed on 46 (24 men, 22 women) obese patients with prediabetes. They were divided randomly into two groups. Patients in intervention (n = 23) and control group (n=23) received 3 gr/day L-arginine and placebo, respectively for 8 weeks. Anthropometric indices, dietary intake and biochemical measurements ((serum total antioxidant capacity (TAC), Glutathione Peroxidase (GPx) and Superoxide Dismutase (SOD)) were performed at the baseline and after 8-week intervention. Results: The mean age and BMI of participants were 44.29±8.65 years old and 28.14±1.35 kg/m2, respectively. At the end of study, in both intervention and control group, percentage of carbohydrate decreased and %fat intake increased compared to the baseline (P0.05). Among measured biochemical factors, only serum TAC level showed significant differences at the end of study in the intervention group compared to the control group (pv, Advanced Pharmaceutical Bulletin; eISSN 2251-7308

Background: Previous trials have reported beneficial effects of isolated and complex fiber supplements in obesity treatment. However, recommending fiber supplements in obese subjects remains controversial. To the best of our knowledge, no systematic review has updated the data on the effects of fiber supplements on obesity since 2010 and the need exists for a systematic review on this topic. Accordingly, a systematic review was undertaken to summarize the efficacy of different types of fiber supplements as a complementary treatment for weight management. Methods: We searched PubMed, Scopus, Cochrane Library and Google Scholar between January 2010 to August 2016 with no language restriction. Considering the inclusion/exclusion criteria and quality assessment score, finally 17 clinical trials met the eligibility criteria and were included. Results: The present study indicated that the efficacy of various fiber supplements on losing weight is variable. Several mechanisms related to physicochemical properties of fibers such as solubility, fermentability and viscosity rates can be involved in their anti-obesity effects. Dextrin, Mannan (gum Arabic) and pectin-rich fiber (lupin kernel) with no dietary interventions indicated a reduction in body weight and energy intake, while from clinical point of view, their effects were not considerable. Conclusion: Overall, findings indicated that the efficacy of fiber supplements on obesity management is dependent on their contents and physicochemical properties. It seems that fiber supplements with no weight-loss interventions did not have considerable antiobesity effects. However, due to limited studies on each type of fiber, findings should be declared by caution. Additional research is needed on comparison of different fiber supplements in similar conditions to clarify the best type and dosage of fiber supplement as a complementary therapy in obesity management.

The association between a low-carbohydrate diet (LCD) score and the risk of diabetes mellitus (DM) is contradictory. This study is a systemic review of cohort studies that have focused on the association between the LCD score and DM. We searched PubMed/Medline, Scopus, Embase, ISI Web of Science, and Google Scholar for papers published through January 2017 with no language restrictions. Cohort studies that reported relative risks (RRs) with 95% confidence intervals (CI) for DM were included. Finally, 4 studies were considered for our meta-analysis. The total number of participants ranged from 479 to 85 059. Among 4 cohort studies, 8 081 cases with DM were observed over follow-up durations ranging from 3.6 to 20 years. A marginal significant association was observed between the highest LCD score and the risk of DM (RR = 1.17; 95% CI: 0.9, 1.51). Moreover, the RRs for studies with energy adjustments showed a significant association (RR: 1.32; 95% CI: 1.17, 1.49; I²: 0%). Based on our findings, study qualities score of less or equal to 7 had a significant influence on the pooled effect size (RR = 1.31, 95%CI: 1.15, 1.49; I²: 0%), whereas the overall RR in the studies with quality score more than 7 was 1.09 (95% CI: 0.73, 1.63). In conclusion, we have found that the highest LCD score was marginally associated with the risk of DM. However, more prospective cohort studies are needed to clarify the effects of the LCD score on the risk of DM. [ABSTRACT FROM AUTHOR]

The aim of the present study was to evaluate the effects of Nigella sativa (NS) oil with calorie restriction on insulin resistance with regard to adiponectin and peroxisome proliferator-activated receptor gamma-2 (PPAR-γ2) gene polymorphisms in obese women. In this double-blind, placebocontrolled, randomized, clinical trial, 100 volunteer obese women were recruited. Participants were randomly divided into an intervention and a placebo group. Each group received a low-calorie diet either with NS oil or placebo for 8 weeks. Pro/Pro, Pro/Ala, TT, TG and GG genotypes were found in 77, 23, 72, 24 and 4%, of the women, respectively. Comparison between the two groups indicated that body weight decreased significantly in the NS group compared to the placebo group independent of the genotypes (-5.1 vs. -2.9 kg; p<0.01). There were significant differences in changes of insulin concentrations (-5.7 vs. -1.7µU/mL; p<0.01) and insulin resistance (HOMA: -1.4 vs. -0.4; p<0.01) in participants with the Pro/Ala vs. Pro/Pro polymorphism in the NS group. In combination with calorie restriction, NS oil decreased weight, independent of the genotypes, but its lowering effect on insulin concentrations and insulin resistance was influenced by the Pro/Ala genotype. More studies are needed to elucidate gene/ intervention interactions on obesity phenotype. [ABSTRACT FROM AUTHOR]

The objective of this study was to identify common barriers to physical activity practice among overweight/obese patients with type 2 diabetes in Iran and their associations with physical activity level. In this cross-sectional study, 146 overweight/obese volunteers with type 2 diabetes were recruited from diabetes clinics in Tabriz, Iran, between July 2012 and March 2013. A Persian version of the long-format International Physical Activity Questionnaire was used to assess physical activity level. A 12-item structured questionnaire was designed to assess physical activity barriers. The validity and reliability of the latter scale were assessed by related measures. An exploratory factor analysis with the principal component analysis extraction method and varimax rotation was performed to extract the underlying factors. Multivariate regression analysis was used to assess the relationship between barriers and physical activity level. About 73% of patients had moderate physical activity. Factor analysis yielded four factors as barriers to physical activity including: (i) negative attitude towards physical activity, (ii) discouragement, (iii) physical problems and (iv) cost/environmental factors. These factors explained about 51% of the total variance. There was a negative relationship between the factor 'physical problems' and physical activity level ( P = 0.024). Overall, there were some barriers to physical activity. Health counsellors should address these barriers to increase the patients' adherence to physical activity recommendations. Physical conditions of the patients must be taken into account. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: The aim of the present study was to determine the accuracy of commonly used predictive formulas of resting metabolic rate (RMR) compared to measured RMR in normal and overweight young females.Methods: In this cross-sectional study, 98 female university students aged 18-30 years with body mass index 18 to 30 kg/m(2) were recruited. Anthropometric indices and body compositions were measured. RMR was measured by indirect calorimetry (FitMate, Cosmed, Rome, Italy) and estimated by 11 predictive formulas. The accuracy of the RMR formulas and mean percentage differences between estimated and measured values were calculated. Paired t test was used to compare estimated and measured RMRs.Result: There were no significant differences between measured and estimated RMR by the 4 commonly used formulas (Mifflin, Cunningham, and World Health Organization [WHO]/Food and Agriculture Organization [FAO]). Among all of the equations, the Mifflin formula showed the lowest bias (-2.97 ± 116.43 kcal/day) at the group level and was the most accurate formula (80.23%) in normal and overweight participants. The over- and underestimated values were about 14% and 5.5%, respectively. In normal and overweight females, Mifflin was the most accurate formula, with 75.51% and 84.61% accuracy, respectively.Conclusion: Given the current lack of a standardized formula that consistently delivers accurate results, the Mifflin formula can be recommended for estimating energy requirements in normal and overweight females in clinical practice.

Aims and Objective: This study investigated the effect of breastfeeding on cardio respiratory fitness (CRF) in students of Kermanshah, Iran.Methods and Materials: In this retrospective cohort study, 246 students with the mean ± SD age of 7.28 ± 0.50 years, mean breastfeeding ± SD duration of 8.20 ± 10.26 months, and body mass index (BMI) of 16.96 ± 3.03 kg/m(2) participated. Students had no CVD, liver or kidney diseases. Children were categorized in three groups of over 6 months breast-fed (>6 months group), less than 6 months breast-fed (≤6 months group), and formula group. The physician measured CRF calculating VO2 max; and reported the results as fitness or no fitness. The probable confounders were gender, BMI, fat-free mass, fat mass, mother's BMI, dietary Poly Unsaturated Fatty Acid (PUFA) and folate, beginning time of supplementary nutrition, physical activity, and birth weight.Results: Breastfeeding more than 6 months was positively associated with CRF (p value < 0.001) before and after adjustment for confounders. The risk ratio (RR) of no CRF was 3.22 times more than >6 months group. VO2 max (ml/kg/min) was significantly the highest in >6 months group (p value = 0.001).Conclusion: Breastfeeding more than 6 months has positive effects on CRF, and the early nutrition may be a predictor for adolescence physical health.

- Abstract
This systematic review of animal studies aimed to identify anti-obesity medicinal herbs with prebiotic properties, and investigate their effects on gut microbiota and metabolic disorders. To obtain the relevant publications, four electronic databases were systematically searched up to June 2019. Out of 1949 publications, 20 articles met the inclusion criteria in this study. Apart from body weight, some cases (n = 11) had reported the effects of medicinal herbs on metabolic parameters, including lipid profile (n = 7) and glycemic status (n = 4). Although some medicinal herbs could be effective in modulating metabolic status and body weight, through making changes in the gut flora, further studies are needed to confirm the efficacy of such herbs in clinical trials. • Garcinia brasiliensis , Grifolafrondosa , Ganodermalucidum , Eugenia Jambolana Lam., can increase the production of short chain fatty acids. • Green coffee, Pu-erh tea, Ganodermalucidum, Chlorella pyrenoidosa, and Polygala tenuifolia can affect obesity. • Some herbs can reduce glucose level through changes in microbiota composition.

- Abstract
Background: Underweight as a public health problem in young women is associated with nutritional deficiencies, menstrual irregularity, eating disorders, reduced fertility, etc. Since resting metabolic rate (RMR) is a necessary component in the development of nutrition support therapy, therefore we determined the accuracy of commonly used predictive equations against RMR measured by indirect calorimetry among healthy young underweight females. Methods: This cross-sectional study was conducted on 104 underweight females aged 18-30 years old with body mass index (BMI) <18.5 kg/m² in 2013 . After collecting anthropometric data, body composition was measured by bioelectric impedance analysis (BIA). RMR was measured by using indirect calorimetry (FitMate™) and was estimated by 10 commonly used predictive equations. Comparisons were conducted using paired t-test. The accuracy of the RMR equations was evaluated on the basis of the percentage of subjects' predicted RMR within 10% of measured RMR. Results: The mean BMI of subjects was 17.3±1.3 kg/m². The measured RMR ranged 736-1490 kcal/day (mean 1084.7±175 kcal/day). Findings indicated that except Muller and Abbreviation, other equations significantly over estimated RMR, compared to measured value (P<0.05). As an individual prediction accuracy, these predictive equations showed poor performance with the highest accuracy rate of 54.8% for Muller equation (22.1% under and 23.1% overprediction) and 43.3% for Abbreviation equation (31.7% under and 25% over-prediction), the percentage bias was 1.8% and 0.63% and RMSE was 162 and 173 kcal/d, respectively. Conclusion: Although Muller equation gave fairly acceptable prediction, more suitable new equations are needed to be developed to help better management of nutritional plans in young underweight people.

- Abstract
Abstract.Background and Aim: Migraine is a unilateral and pulsating headache associated with nausea, photophobia, vomiting, and sensitivity to light. Low vitamin B2can lead to mitochondrial dysfunction and may have an effect on migraine pathogenesis. The aim of the present study was to carry out a review of existing evidence regarding the effects of riboflavin (vitamin B2) supplementation on migraine prophylaxis in adults and children. Material and Methods: We searched the databases of PubMed, Science Direct, Google Scholar, and Springer between 1990 and December 2013. Key words included vitamin B2, riboflavin, migraine, vomiting headache, and prevention. We limited our search to human studies in the English language. Review articles and abstracts from symposiums and conferences were excluded. Results: Finally, eleven eligible articles were found: seven involved studies with adults and four involved studies with children. The results indicated that supplementation with vitamin B2in adults can play a positive role in reducing the frequency and duration of migraine attacks with no serious side effects. Conclusions: It seems that riboflavin is a safe and well-tolerated option for preventing migraine symptoms in adults, however, there is insufficient evidence to make recommendations regarding vitamin B2as an adjunct therapy in adults and children with migraine.

Purpose: To assess COVID-19-specific diabetes worries, and to determine characteristics of people with high levels of these worries among people with type 2 diabetes (T2D) following the continuation of the pandemic and occurrence of multiple waves of COVID-19 in Iran. Methods: An interviewer-based, cross-sectional study was conducted using 500 T2D people in a diabetes specialty clinic. The questionnaire package comprised five parts: sociodemographic and clinical characteristics, COVID-19-specific worries, diabetes-related distress, feelings of isolation and changes in diabetes-specific behaviors. Clinical history and serum measurements were collected from electronic medical records. Descriptive statistics and logistic regressions were performed in the study. Results: Worries related to COVID-19 pandemic were highly prevalent in T2D people. Around 60% were worried about being severely affected due to diabetes if infected with COVID-19 and being described as a high-risk group for COVID-19, and more than half about being possibly faced with lack of diabetes medications. Logistic regressions demonstrated that being female, higher age, diabetes-related complications, duration of diabetes, insulin use, feeling isolation, diabetes-related distress and having changed self-management behaviors were associated with being more worried about diabetes and COVID-19. Conclusion: Diabetes-related worries relating to the COVID-19 were strongly associated with poorer psychosocial status. Findings emphasize the importance of conveying up-to-date information regarding diabetes and COVID-19 that patients want and need to know, also of providing emotional support associated with COVID-19-specific diabetes worries.

OSTEOPOROSIS , *RESEARCH protocols , *LUMBAR pain , *BONE density , *FRACTURE healing , *PATIENT compliance - Abstract
Background: Osteoporotic fractures can result in significant health complications and an increased risk of death. Registry studies could provide better treatment options and improve patient outcomes by providing useful information about the disease. The present study describes the protocol for an osteoporosis registry in Iran. Materials and methods: This registry is a prospective multicenter cohort study recruiting patients with osteoporosis from Iran. The inclusion criteria of the study are individuals diagnosed with primary or secondary osteoporosis according to the diagnostic criteria of the study; patients will be identified and recruited from outpatient clinics in this registry. All patients diagnosed with primary or secondary osteoporosis are the target population of the study. Our expected sample size is 1000 participants and the study will continue for at least 2 years. The measurements of the Iranian Osteoporosis Registry include four parts: (i) variables measured by the specific questionnaires package, (ii) bone mineral density (BMD, (iii) clinical examination, and (iv) lab data. The final questionnaire package includes "demographics information", "socioeconomic status", "lifestyle", "reproductive health", "medical history and medication", "Osteoporosis diagnosis gap", "Osteoporosis adherence and treatment gap", "fracture history and fall risk assessment", "FRAX ® tool ", "hospitalization and death outcomes", "low back pain", "hospitalization history", "attitude toward osteoporosis", "osteoporosis awareness", "osteoporosis related-performance", "quality of life (Iranian version of SF12 questionnaire)", and "food frequency questionnaire (FFQ)". Clinical examination of this registry includes anthropometric measurements (including height, weight, body mass index (BMI), waist circumference, hip circumference, and right wrist circumference), and blood pressure. The baseline questionnaires will be filled out right after patients are diagnosed with osteoporosis and then osteoporotic patients will be followed up regularly on a yearly basis. In the follow-up visit, variables that may have changed over time are updated. The main outcomes include registration of fall, fracture, hospitalization, medication adherence, and death. An online web-based user-friendly software is also developed for data collection. Data analysis will be conducted with the collaboration of data-mining experts and epidemiologists at the end of each follow-up. Conclusion: The Iran Osteoporosis Registry will be a valuable source of information regarding osteoporosis outcomes (i.e. fractures, hospitalizations, adherence, and death at the national level), and its results will be very beneficial and practical for policy makers in the field of musculoskeletal diseases.

Abstract
Introduction: A growing number of studies have thus far showed the association between type 2 diabetes mellitus (DM) and the intestinal microbiome homoeostasis. As reported, the gut microflora can be significantly different in patients with type 2 DM (T2DM) compared to those in healthy individuals.Methods: The authors collected the relevant articles published until 2022 and these are carefully selected from three scientific databases based on keywords.Discussion: This review highlights research on the anti-diabetic properties of berberine (BBR)-induced glucagon-like peptide-1 (GLP-1), as a glucose-lowering factor and a balance regulator in the microbial flora of the intestines, which plays an important role in adjusting the signalling pathways affecting insulin secretion.Results: Considering the anti-diabetic characteristics of the BBR-induced GLP-1, BBR makes a promising complementary treatment for reducing the clinical symptoms of DM by reducing the hyperglycaemia. Berberin might be a safe and effective drug for T2DM with little or no adverse effects. Highlights Berberine induces GLP-1 insulin secretion by PLC2 pathway in the intestinal Berberine-induced GLP-1 decreases mitochondrial stress and relocates cytochrome c out of the mitochondria. Berberine induces GLP-1 secretion in the intestine by altering the bacterial profile, thus could possibly lighten diabetes symptoms Berberine-induced SCFA production, SCFA causes GLP-1 secretion from the intestinal L-Cell. Preventing mitochondrial damage, reducing adipose tissue fat, and reducing oxidative stress are thus among the results of BBR-induced GLP-1.

The aim of the study was to report the burden of type one diabetes mellitus (T1DM) by sex, age, year, and province in Iran over the past 30 years, according to data provided by the global burden of disease (GBD) study. Incidence, prevalence, death, disability-adjusted life-years (DALYs), years of life lost, and years lived with disability due to T1DM by age groups and sex was reported for 31 provinces of Iran from 1990 to 2019 with their 95% uncertainty intervals (UI). In 2019, national age-standardized incidence (11.0 (95% UI: 8.9–13.5)), prevalence (388.9 (306.1–482.1)), death (0.7 (0.6–0.8)), and DALYs (51.7 (40.9–65.1)) rates per 100,000 wre higher than 1990 except for death. Also, the mortality to incidence ratio reduced in all provinces over time particularly after 2014 as well. GBD data analysis showed that age-standardized incidence and prevalence rates of T1DM have increased, the death rate reduced, and DALYs remained unchanged during the past 30 years in Iran and its 31 provinces. death rate reduced and DALYs remained unchanged during the past 30 years in Iran and its 31 provinces.

Background: A considerable amount of research funding goes to diabetes management strategies to improve therapeutic goals and reduce the burden of diabetes. A vast amount of the budget is wasted due to unnecessary studies. A scoping review is a pivotal study to overview the available evidence and avoid research waste. In this review, we will try to find out the scope of available studies on diabetes management interventions, identify associated research gaps, and prioritize future studies. Method: We will carry out a study using Arksey and O'Malley's scoping review framework. We will search the Scopus and PubMed databases from 01/01/2015 till 01/01/2020. Only original articles related to pharmacological and non-pharmacological management interventions will be included. These interventional studies should be conducted on the Iranian population. After data extraction, a descriptive data analysis will be used to present information in different charts or tables. We will evaluate related published articles based on their document type, level of evidence, type of diabetes, subject area, interventions types, main findings and outcomes. Discussion: This study represents the first attempt to sum up available studies related to diabetes management interventions performed in Iran. The results of this study will be useful for all the stakeholders and policy-makers involved in diabetes research. It can help clinicians to be informed about studies on management interventions and can guide scientists eager to diabetes research to choose their future research plans based on diabetes research requirements and gaps.

DIABETES , *PHYSICAL activity , *APPLIED sciences , *CLINICAL trials - Abstract
Background: Mapping the available evidence can be used to inform current diabetes research, identify relevant gaps, and prioritize future research. In this regard, we mapped diabetes research performed in Iran. Method: We searched the Scopus and PubMed databases from 01/01/2015 till 01/01/2020 using keywords such as diabetes and Iran. The included articles were classified according to their document types, level of evidence, and subject areas. Results: The majority of the included articles (53%) were related to diabetes types, followed by complications (28%). Most of the documents were original articles (82%), and reviews were 18% of the publications. Systematic reviews constitute only 6% of the total documents. Observational studies were the most common types of study designs (26%), followed by clinical trials (20%). Moreover, topics on control and management of diabetes were the most prevalent subject areas (58%), and fewer studies were on preventive strategies (6%). In diabetes management studies, less attention has been paid to evaluate psychological (10%), educational (9%), and physical activity-related (7%) interventions. There was a shortage of secondary studies related to physical activity, psychology, diagnostic, and screening-related studies. Conclusion: To fill diabetes research gaps, more investment in cost-effectiveness interventions, such as preventive strategies and behavioral self-management programs, need. Moreover, we need to pay more attention on applied sciences and real world evidence to bridge translational gaps from bench to bedside. In this regard, further data synthesis can be helpful in evaluating the effectiveness of the available studies and avoiding unnecessary investigations. [ABSTRACT FROM AUTHOR]

Background & Aims: Nutrition is one of main environmental factor affecting obesity and its related complications such as diabetes and dyslipidemia. Due to growing prevalence of obesity across the world, it seems that nutritional advice alone is not able to combat this health problem. The present overview aimed to summarize the roles of personalized nutrition (PN) in obesity and diabetes management. Methods: Scopus, PubMed and Google scholar were searched up to February 2021 to find relevant studies with English language in which the roles of PN in obesity and diabetes management were examined. Results: Recent evidence revealed the importance of gene-environment interactions for management of diabetes mellitus and obesity. Moreover, microbiome research showed that personalized diet based on a combination of clinical and microbial features is likely to improve responses to therapeutic interventions. Epigenetics as well as genetic and environmental factors can also contribute to the treatment. In addition, articles showed significant roles of epigenetics and gut microbiome on providing an individualized diet for obese and diabetic patients. Conclusion: PN compare to conventional diet can better improve metabolic status in obese and diabetic patients. Considering genetic differences and microbiome patterns along with environmental factors and their interactions are recommended for obesity and diabetes management. This approach can increase success in promoting health and preventing complications related to diabetes and obesity. [ABSTRACT FROM AUTHOR]

- 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., (© 2024. The Author(s).)

- Abstract
Cancer is categorized as one of the life-threatening disease in the world, which has recently been associated with a significant increase in the incidence and prevalence rate. Hence, the discovery of effective approaches for prevention, early diagnosis, and effective treatment for cancer has been prioritized by oncology researchers. In recent decades, mesenchymal stem cells show great potential to advance the field of regenerative medicine and oncology research due to representing prominent characteristics. Recently, studies indicate that mesenchymal stem cells can play an important role by secreting extracellular vesicles like exosomes in modulating the biological functions of target cells through paracrine regulation. Indeed, the exosomes derived from mesenchymal stem cells can represent the same therapeutic potential as parent cells with fewer side effects. Therefore, it can be demonstrated that exosomes can be a suitable drug delivery candidate in regenerative medicine and targeted therapy. It is also noteworthy that as the use of exosome therapy becomes more common in clinical studies, the importance of improving basic criteria such as safety, efficiency, and quality of stem cell products will also be highlighted. Based on this concept, the good manufacturing practice principles were put forward to examine the standard of cell products from different qualitative and quantitative aspects to progress the cell therapy. In other words, the principles of good manufacturing practice should be observed not only in the extraction and isolation of stem cells but also in the extraction of products related to stem cells such as exosomes in the field of treatment., (© 2023.

- Abstract
Vitiligo is a skin condition affecting 1% of the global population, causing non-scaly, chalky-white macules on the skin and hair. It is caused by the pathologic destruction of melanocytes, which produce melanin. Research has focused on the abnormalities of melanocytes and their interaction with neighboring keratinocytes. Current treatments are mainly immunosuppressive drugs and UV radiation, which are scarce and ineffective. To treat vitiligo, regenerative medicine techniques, such as cell-based and cell-free methods, are recommended. Keratinocyte cell transplantation has shown promising results in treating vitiligo. Moreover, studies suggest individualized therapy for diseases can be provided by reprogramming somatic cells into induced pluripotent stem cells. On the other hand, differentiation into particular cell types is a key component of induced pluripotent stem cells-based treatment. In this chapter, the differentiation and validation of human induced pluripotent stem cells into a keratinocyte as a therapeutic option in vitiligo will be discussed., (© 2024.

- Abstract
Diabetic foot ulcers (DFUs) pose a significant threat to the health and well-being of individuals with diabetes, often leading to lower limb amputations. Fortunately, epidermal stem cell therapy offers hope for improving the treatment of DFUs. By leveraging 3D culture techniques, the scalability of stem cell manufacturing can be greatly enhanced. In particular, using bioactive materials and scaffolds can promote the healing potential of cells, enhance their proliferation, and facilitate their survival. Furthermore, 3D tissue-mimicking cultures can accurately replicate the complex interactions between cells and extracellular matrix, thereby ensuring that the stem cells are primed for therapeutic application. To ensure the safety and quality of these stem cells, it is essential to adhere to good manufacturing practice (GMP) principles during cultivation. This chapter provides a comprehensive overview of the step-by-step process for GMP-based 3D epidermal stem cell cultivation, thus laying the groundwork for developing reliable regenerative medicine therapies., (© 2024.

- Abstract
Natural killer (NK) cells are a part of a sophisticated immune system that is necessary for the skin because it is a crucial organ that is continually exposed to environmental influences. Recent studies have shown that NK cell incorporation into three-dimensional (3D) organotypic culture systems for human skin stem cells provides a physiologically relevant environment to study the interactions between immune cells and skin cells, making it a powerful tool for simulating skin diseases and researching these interactions. It has been shown that adding NK cells to 3D organotypic culture systems can improve keratinocyte differentiation and control inflammation in a variety of skin conditions, including psoriasis. In order to increase our knowledge of skin diseases and immune cell interactions, this work intends to propose an optimum approach for adding NK cells to a 3D organotypic culturing system for human skin stem cells. By better comprehending these relationships, researchers hope to develop novel treatments for skin diseases that are more effective and cause fewer side effects than current treatments. To completely understand the mechanisms underlying these interactions and to create new treatments for skin diseases, more research is required. In conclusion, NK cell integration into 3D organotypic culture systems offers a potent tool to investigate immune cell interactions with skin cells in a physiologically appropriate setting, which may result in major improvements in the treatment of skin diseases., (© 2023.

- Abstract
Background: Inflammation and cardiometabolic risk factors can be involved in developing type 2 diabetes mellitus (T2DM). This study aimed to investigate and compare the association between a pro-inflammatory diet and cardiometabolic risk factors in patients with T2DM and non-T2DM cases., Methods: In this cross-sectional population-based study, considering the baseline data of the Ravansar Non-Communicable Disease (RaNCD) cohort, patients with T2DM (n = 785) and non-T2DM cases (n = 8254) were included. The dietary inflammatory index (DII) was calculated using a food frequency questionnaire (FFQ) and was classified into four groups (quartiles) with lowest to highest scores. Logistic regression analysis was conducted to determine the association between DII and cardiometabolic risk factors in both groups., Results: The participants were 9,039 (4140 men and 4889 women) with a mean age of 47.4 ± 8.2 years; the mean body mass index (BMI) and DII were 27.49 ± 4.63 kg/m
2 and - 2.49 ± 1.59, respectively. After adjustment for confounding factors, we found that DII can increase the risk of T2DM by 61% (95% CI 1.27 to 2.05, P < 0.001). A comparison of two groups revealed that the association of DII, obesity/overweight and dyslipidemia were also significant in both diabetic (P < 0.05) and non-diabetic cases (P < 0.05). However, no significant association was found between DII, MetS, and hypertension in either of the groups. The association between DII and cardiovascular diseases (CVDs) was only significant in diabetic patients (1.65; 95%CI: 1.02 to 2.65, P = 0.04) and T2DM showed an interaction with the association between DII and CVDs., Conclusion: Inflammatory potential of diet may increase the risk of T2DM. Although it can increase the risk of some cardiometabolic risk factors in both diabetic and non-diabetic cases, its effects were greater among patients with T2DM. However, further prospective studies are required to confirm these associations., (© 2023. The Author(s).)- Published

- Abstract
Objectives: The aim of the present study was to evaluate the link between the dietary insulin index (DII) and dietary insulin load (DIL) and cardiometabolic risk factors in patients with type 2 diabetes mellitus (T2DM)., Method: In this cross-sectional population-based study, 827 participants with diabetes were included based on the RaNCD (Ravansar Non-Communicable Disease) cohort study baseline data. DII and DIL were calculated based on standard formulas using food insulin index values published earlier. Logistic regression analysis was used to determine the association of DII and DIL with cardiovascular risk factors., Results: A significantly direct association was shown between DII and metabolic syndrome (MetS; odds ratio [OR], 1.32; 95% confidence interval [CI], 1.05-2.50). The odds of developing abdominal obesity in patients with the highest DII were almost twice as high as those with the lowest DII (OR, 2.06; 95% CI, 1.02-4.99). Patients in the top quintile of DIL had twice the odds of being obese than those in the bottom quintile. Furthermore, positive associations were found between DIL and both MetS (OR, 1.98; 95% CI, 1.10-4.21) and waist circumference (OR, 2.90; 95% CI, 1.10-7.20)., Conclusion: Higher DII and DIL were positively related to greater risks for both MetS and abdominal obesity among patients with T2DM. Additionally, higher DIL was associated with a higher risk for obesity in the Ravansar population. However, further prospective investigations are needed to clarify the cause-and-effect link between DII, DIL, and cardiovascular risk factors in patients with T2DM., Competing Interests: Declaration of Competing Interest Authors declared no conflict of interest., (Copyright © 2022.

- Abstract
Animal studies are recognized as a significant step forward in the bridging between drug discovery and clinical applications. Animal models, due to their relative genetic, molecular, physiological, and even anatomical similarities to humans, can provide a suitable platform for unraveling the mechanisms underlying human diseases and discovering new therapeutic approaches as well. Recently, zebrafish has attracted attention as a valuable experimental and pharmacological model in drug discovery and development studies due to its prominent characteristics such as the high degree of genetic similarity with humans, genetic manipulability, and prominent clinical features. Since advancing a theory to a valid and reliable observation requires the manipulation of animals, it is, therefore, essential to use efficient modeling methods appropriate to the different aspects of experimental conditions. In this context, applying several various approaches such as using chemicals, pathogens, and genetic manipulation approaches allows zebrafish development into a preferable model that mimics some human disease pathophysiology. Thus, such modeling approaches not only can provide a framework for a comprehensive understanding of the human disease mechanisms that have a counterpart in zebrafish but also can pave the way for discovering new drugs that are accompanied by higher amelioration effects on different human diseases., (© 2021.

- Abstract
Background: Support for breastfeeding is a public health priority. One of the major factors that can negatively affect breastfeeding is the lack of breast milk. There are many instructions on the subject of breast milk in Iranian traditional medicine resources. This article attempts to investigate causes and reasons for the lack of breast milk from the perspective of the great scholars in this field., Methods: This study reviews the literature based on the Iranian traditional medicine. The literature review included traditional medicine resources and a survey of reputable databases using keywords such as "morzae", "sady", "pestan", "sheer", "sheerkhar", and "hifzossehhe". The content analysis was used after collecting data., Results: According to the viewpoint stated in traditional medicine literature, the primary substance for milk production is blood that transforms to milk after crossing the breast glandular tissue. The main causes of milk shortage can be classified into four categories, namely food-related factors, factors related to blood impaired, factors related to breast tissue and psychological and physical factors. One of the main reasons for milk shortage is the impaired quality and quantity of food. Appropriate mizaj of breast tissue is required for adequate milk production as it develops sufficient ability to absorb and transform the substance into milk. On the other hand, the ability of breast tissue is greatly influenced by the main organs of the body, particularly the heart; being the core of understanding psychological factors. Thus, psychological factors can have a significant effect on the process of milk production., Conclusion: Due to the importance of breastfeeding, reflection on other viewpoints, such as those mentioned in Iranian traditional medicine, could pave the way towards new research areas. It could also steer policies towards an extra focus on breastfeeding by mothers.
