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

BACKGROUND: Appropriate service delivery, access to high quality of cares and optimal management of type 2 diabetes mellitus (T2DM) can decrease the risk of micro and macro vascular complications and mortality. Therefore, monitoring the quality of diabetes care, including keeping glycemic levels at an optimal level, is crucial. The aim of this study was to evaluate processes and outcome-related quality of care indicators, in T2DM using retrospective patient-level data from 2013 to 2017 in 15 Tertiary Diabetes Care Centers in Iran. METHOD: A retrospective observational study was conducted among 1985 T2DM patients at public, semipublic and private diabetes centers. Annual tests for HbA1c, serum lipid (LDL), and screening for nephropathy were used to evaluate process-related indicators; and intermediate biomedical markers including HbA1c, blood pressure (BP), and LDL cholesterol, were used to assess outcome-related indicators. RESULTS: Data were extracted from 15 diabetes centers in five provinces in Iran. 62.7% of the patients were female, and the mean duration of diabetes in the patients was 14.7 years. Evaluation of process-related indicators showed that only 9% of patients took the HbA1c test. The percentage of the patients without annual low-density lipoprotein (LDL) test decreased from 13% in 2013 to 7% in 2017. The results of achieving to all indicators concurrently (ABC care) showed that less than 2% of the patients met the criteria of optimal process-related quality indicators. The mean percentage of the patients with HbA1c under 7%, blood pressure (BP) less than 130/80 mmHg, and LDL less than 100 mg/dl in the selected provinces were 32.4, 55, and 71 respectively. However, the average of total achievement in ABC goals was 14.2%. CONCLUSION: Our findings showed that the management of T2DM in all selected provinces was far from the optimal control in both processes and outcome-related indicators and therefore needs serious consideration and improvement.

ABSTRACT

BACKGROUND: Diabetes mellitus (DM) and its cardiovascular disease (CVD) complication are among the most frequent causes of death worldwide. However, the metabolites linking up diabetes and CVD are less understood. In this study, we aimed to evaluate serum acylcarnitines and amino acids in postmenopausal women suffering from diabetes with different severity of CVD and compared them with healthy controls. METHODS: Through a cross-sectional study, samples were collected from postmenopausal women without diabetes and CVD as controls (n = 20), patients with diabetes and without CVD (n = 16), diabetes with low risk of CVD (n = 11), and diabetes with a high risk of CVD (n = 21) referred for CT angiography for any reason. Metabolites were detected by a targeted approach using LC-MS/MS and metabolic -alterations were assessed by applying multivariate statistical analysis. The diagnostic ability of discovered metabolites based on multivariate statistical analysis was evaluated by ROC curve analysis. RESULTS: The study included women aged from 50-80 years with 5-30 years of menopause. The relative concentration of C14:1, C14:2, C16:1, C18:1, and C18:2OH acylcarnitines decreased and C18 acylcarnitine and serine increased in diabetic patients compared to control. Besides, C16:1 and C18:2OH acylcarnitines increased in high-risk CVD diabetic patients compared to no CVD risk diabetic patients. CONCLUSION: Dysregulation of serum acylcarnitines and amino acids profile correlated with different CAC score ranges in diabetic postmenopausal women.

ABSTRACT

A novel series of phenoxymethybenzoimidazole derivatives (9a-n) were rationally designed, synthesized, and evaluated for their α-glycosidase inhibitory activity. All tested compounds displayed promising α-glycosidase inhibitory potential with IC50 values in the range of 6.31 to 49.89 µM compared to standard drug acarbose (IC50 = 750.0 ± 10.0 µM). Enzyme kinetic studies on 9c, 9g, and 9m as the most potent compounds revealed that these compounds were uncompetitive inhibitors into α-glycosidase. Docking studies confirmed the important role of benzoimidazole and triazole rings of the synthesized compounds to fit properly into the α-glycosidase active site. This study showed that this scaffold can be considered as a highly potent α-glycosidase inhibitor.

ABSTRACT

OBJECTIVE: To examine the effect of letrozole on oocyte quality and pregnancy outcome in assisted reproductive technology (ART). METHODS: This double blind placebo controlled clinical trial was conducted in Vali-Asr Infertility Center. Infertile women candidate for IVF that underwent antagonist protocol were selected. Eligible women randomly allocated into treatment (letrozole/Let group) and control (placebo) group. Participants received letrozole 5 mg/day or placebo at the time of gonadotropin start until trigger day in the same manner. Number of oocyte retrieved, metaphase II oocyte number, high grade oocyte number (G1), high quality embryo, Chemical and clinical pregnancy rate and OHSS (ovarian hyperstimulation syndrome) rate was recorded. 216 infertile women (104 in letrozole and 112 in the control group) were evaluated. RESULTS: In the Let group estradiol level was significantly lower (p_value < .001) and testosterone significantly higher than in the control group (p_value = .02). The number of retrieved oocytes, MII oocytes, G1 oocytes, and 2PN was significantly lower in the Let group (p < .05). No significant difference was found in the day of stimulation, total gonadotropin dose, OHSS rate, and clinical pregnancy rate between the two groups (p > 0.05). CONCLUSIONS: According to the results, letrozole may reduce oocyte quality and cause poor IVF outcomes as well.

ABSTRACT

Fourteen novel 4,5-diphenyl-imidazol-1,2,3-triazole hybrids 8a-n were synthesized with good yields by performing click reaction between the 4,5-diphenyl-2-(prop-2-yn-1-ylthio)-1H-imidazole and various benzyl azides. The synthesized compounds 8a-n were evaluated against yeast α-glucosidase, and all these compounds exhibited excellent inhibitory activity (IC50 values in the range of 85.6 ± 0.4-231.4 ± 1.0 µM), even much more potent than standard drug acarbose (IC50 = 750.0 µM). Among them, 4,5-diphenyl-imidazol-1,2,3-triazoles possessing 2-chloro and 2-bromo-benzyl moieties (compounds 8g and 8i) demonstrated the most potent inhibitory activities toward α-glucosidase. The kinetic study of the compound 8g revealed that this compound inhibited α-glucosidase in a competitive mode. Furthermore, docking calculations of these compounds were performed to predict the interaction mode of the synthesized compounds in the active site of α-glucosidase. A novel series of 4,5-diphenyl-imidazol-1,2,3-triazole hybrids 8a-n was synthesized with good yields by performing click reaction between the 4,5-diphenyl-2-(prop-2-yn-1-ylthio)-1Himidazole and various benzyl azides. The synthesized compounds 8a-n were evaluated against yeast α-glucosidase and all these compounds exhibited excellent inhibitory activity (IC50 values in the range of 85.6 ± 0.4-231.4 ± 1.0 µM), even much more potent than standard drug acarbose (IC50 = 750.0 µM).

ABSTRACT

BACKGROUND: Storage of biological samples may alter the values of an analyte compared to that of initial measurement. Therefore, an optimal storage condition for every analyte in serum and whole blood samples needs to be determined. The aim of this study was to investigate stability of 34 analytes at different time and temperature conditions of storage. METHODS: This study assessed the stability of hematological parameters in whole blood sample and common biochemical analytes in serum of 40 diabetic patients after 24 and 48 hours in 2 - 8°C and after 30 days in -20°C of sample collection. The mean values of analytes in 3 different storage conditions were measured and compared to that of initial values. RESULTS: Most of the examined biochemical analytes and hematological parameters were stable up to 48 hours at 2 - 8°C after sample collection. Most of the negative changes were negligible but PTH level dramatically decreased after 48 hours in 2 - 8°C. In addition, although a clear increase in the concentration of triglycerides, Cr, Urea, T4, and 25-OH vitamin D3 was observed, it was not significant. Furthermore, a statistically significant difference was observed in the values of ALT, Ca, and T4 among the different conditions of storage. Also, values of HbA1c did not show any significant statistical changes among the 3 different conditions of storage. CONCLUSIONS: Taken together, it seems that most of the analytes in the serum of diabetic patients as well as HbA1c are stable up to 30 days of storage.

ABSTRACT

Apelin, a member of the adipokine family, is widely distributed in the body and exerts cytoprotective effects on many organs. Apelin isoforms are involved in different physiological processes, including regulation of the cardiovascular system, cardiac contractility, angiogenesis, and energy metabolism. Several investigations have been performed to study the effect of apelin on stem cell therapy. This review aims to summarize the literature representing the effects of apelin on stem cell properties. Furthermore, this review discusses the therapeutic potential of apelin-treated stem cells for cardiovascular diseases and demonstrates the effect of stem cells overexpressing apelin on energy metabolism. Stem cells with their unique characteristics play a crucial role in the maintenance of tissue integrity. These cells participate in tissue regeneration via multiple mechanisms. Although preclinical and clinical studies have demonstrated the therapeutic potential of stem cells in various diseases, their application in regenerative medicine has not been efficient. A number of strategies such as genetic modification or treatment of stem cells with different factors have been used to improve the efficacy of cell therapy and to increase their survival after transplantation. This article reviews the effect of apelin treatment on the efficacy of cell therapy.

ABSTRACT

Twenty three fused carbazole-imidazoles 6a-w were designed, synthesized, and screened as new α-glucosidase inhibitors. All the synthesized fused carbazole-imidazoles 6a-w were found to be more active than acarbose (IC50 = 750.0 ±â€¯1.5 µM) against yeast α-glucosidase with IC50 values in the range of 74.0 ±â€¯0.7-298.3 ±â€¯0.9 µM. Kinetic study of the most potent compound 6v demonstrated that this compound is a competitive inhibitor for α-glucosidase (Ki value = 75 µM). Furthermore, the in silico studies of the most potent compounds 6v and 6o confirmed that these compounds interacted with the key residues in the active site of α-glucosidase.

ABSTRACT

A novel series of quinazolinone-1,2,3-triazole hybrids 10a-p were designed, synthesized, and evaluated for their in vitro α-glucosidase inhibitory activity leading to efficient anti-diabetic agents. All synthesized compounds exhibited good inhibitory activity against yeast α-glucosidase (IC50 values in the range of 181.0-474.5 µM) even much more potent than standard drug acarbose (IC50 = 750.0). Among them, quinazolinone-1,2,3-triazoles possessing 4-bromobenzyl moiety connected to 1,2,3-triazole ring (10g and 10p) demonstrated the most potent inhibitory activity towards α-glucosidase. Compound 10g inhibited α-glucosidase in a competitive manner with Ki value of 117 µM. Furthermore, the binding modes of the most potent compounds 10g and 10p in the α-glucosidase active site was studied through in silico docking studies. Also, lack of cytotoxicity of compounds 10g and 10p was confirmed via MTT assay.

ABSTRACT

BACKGROUND: Diabetic nephropathy (DN) is the leading cause of end-stage renal disease worldwide. Several factors are known to contribute to the development and progression of diabetic nephropathy. Different microRNAs have been shown to contribute in the pathogenesis of DN. This study, aimed to evaluate the expression level of circulating miR-155 in patients with diabetic nephropathy. METHODS: In this case-control study, 83 diabetic patients and normal subjects were evaluated in four groups of normal healthy subjects without diabetes and nephropathy, diabetes without nephropathy, diabetes with microalbuminuria, and diabetes with macroalbuminuria. After RNA extraction from serum and cDNA synthesis, the expression of circulating miR-155 was evaluated by quantitative polymerase chain reaction (qPCR). RESULTS: Expression level of cell-free miR-155 was significantly lower in diabetics compared to the normal healthy controls (p < 0.05). However, no significant difference was found in miR-155 expression level between different diabetes groups with different conditions of kidney function. Furthermore, we detected a significant negative correlation between cell-free miR-155 expression and GFR only in patients with microalbuminuria (r = -0.70, p = 0.001). CONCLUSIONS: It seems that miR-155 can discriminate diabetic and nondiabetic status, but is not an appropriate biomarker for tracking of macroalbuminuria.

ABSTRACT

BACKGROUND: HbA1c concentration is an indicator of the development of long-term complications in diabetic pa-tients. Different sample storage conditions could affect HbA1c values and consequently, clinician's diagnosis. In this study, we studied the effects of various temperatures of storage over time on HbA1c results. METHODS: A total of 40 fresh whole blood samples with various levels of HbA1c were selected for separate HbA1c measurements at three different temperatures (-20°C, 4°C, and 25°C) on subsequent days (0, 7, 14, and 21 days af-ter sample collection) with Cobas Integra 400 assays (Roche Diagnostics, Mannheim Germany). RESULTS: The value of HbA1c at initial measurement (7.05 ± 1.45) was insignificantly higher than results of temper-ature of -20°C and 4° but compared to results at the temperature of 25°C, (6.08% ± 0.86 % after day 7, 5.52% ± 0.80 after day 14, 4.81 % ± 0.66 after day 21) values of initial measurements were significantly higher. CONCLUSIONS: We concluded that the refrigerator or freezer storage temperature is applicable for the measurement of HbA1c by Cobas Integra 400 without adverse effects on the stability of samples on subsequent days.

ABSTRACT

A novel series of acridine linked to thioacetamides 9a-o were synthesized and evaluated for their α-glucosidase inhibitory and cytotoxic activities. All the synthesized compounds exhibited excellent α-glucosidase inhibitory activity in the range of IC50 = 80.0 ±â€¯2.0-383.1 ±â€¯2.0 µM against yeast α-glucosidase, when compared to the standard drug acarbose (IC50 = 750.0 ±â€¯1.5 µM). Among the synthesized compounds, 2-((6-chloro-2-methoxyacridin-9-yl)thio)-N-(p-tolyl) acetamide 9b displayed the highest α-glucosidase inhibitory activity (IC50 = 80.0 ±â€¯2.0 µM). The in vitro cytotoxic assay of compounds 9a-o against MCF-7 cell line revealed that only the compounds 9d, 9c, and 9n exhibited cytotoxic activity. Cytotoxic compounds 9d, 9c, and 9n did not show cytotoxic activity against the normal human cell lines HDF. Kinetic study revealed that the most potent compound 9b is a competitive inhibitor with a Ki of 85 µM. Furthermore, the interaction modes of the most potent compounds 9b and 9f with α-glucosidase were evaluated through the molecular docking studies.

ABSTRACT

A novel series of ciprofloxacin-dithiocarbamate hybrids 7a - 7l were designed, synthesized, and evaluated against Gram-positive and Gram-negative bacteria. A significant part of the title compounds showed considerable antibacterial activity against Gram-positive species. The most potent compound against Gram-positive bacteria was 2-chloro derivative 7h and the most potent derivative against Gram-negative bacteria was 3-chloro compound 7i. In vitro antibacterial evaluation of compound 7h against clinically isolated bacteria methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) showed that this compound acted better than ciprofloxacin against the latter bacteria. Docking study of compound 7h in the active site of S. aureus DNA gyrase revealed that this ciprofloxacin-dithiocarbamate derivative interacted with the main components of the active site of the enzyme.

ABSTRACT

PURPOSE: The aim of this study was to investigate the association between pre-pregnancy body mass index (BMI) and gestational diabetes mellitus (GDM). METHODS: This prospective study was conducted on 256 pregnant women without diabetes referred for prenatal care in the first trimester of pregnancy to two referral University Hospitals (Shariati and Arash Hospitals) during the years 2012 and 2013. Eligible participants were selected consecutively and were followed until delivery and 6 weeks after that. Body weight and fasting plasma glucose were measured in each trimester, and BMI was calculated. Incidence of GDM was recorded, and BMI in this group was compared with those without GDM. RESULTS: Mean age of women was 28.70 ± 5.57 years and among them, 78 women (30.5 %) developed GDM of which 21 were obese (52.5 %), 25 overweight (27.8 %), and 32 (25.4 %) were normal weight (p = 0.004). Pre-pregnancy obesity (OR 2.74, 95 % CI 1.28-5.88, p = 0.009), family history of diabetes (OR 2.01, 95 % CI 1.13-3.56, p = 0.016), and maternal age more than 30 years (OR 2.20, 95 % CI 1.25-3.88, p = 0.006) were three independent predictors for GDM, and pre-pregnancy obesity was the most potent predictor of GDM. CONCLUSION: Women with high BMI and obesity have a significantly higher risk for developing GDM. Pre-pregnancy obesity, family history of diabetes, and age more than 30 years are three independent risk factors for GDM.

ABSTRACT

Dysmenorrhea is common among women of reproductive age. This study aim was to investigate the effect of vitamin D (vit D) supplementation in treatment of primary dysmenorrhea with vit D deficiency. A randomized double-blind placebo-controlled clinical trial was conducted on 60 women with primary dysmenorrhea and vit D deficiency referred to our clinic at Arash Women's Hospital from September 2013 to December 2014. Eligible women were randomly assigned into treatment and control groups (30 in each group). Individuals in the treatment group received 50 000 IU oral vit D and the control group received placebo weekly for eight weeks. After two months of treatment, there was a significant difference in serum vit D concentration between the two groups (p < 0.001). Pain severity decreased significantly in treatment group after eight weeks of treatment. There was a significant difference in pain intensity between the two groups after eight weeks of treatment and one month after the end of treatment (p < 0.001 for both). A weekly high dose (50 000 IU) oral vit D supplementation for eight weeks in patients with primary dysmenorrhea and vit D deficiency could improve pain intensity.

ABSTRACT

Gestational diabetes mellitus (GDM) is increasing worldwide. The aim of this study was to investigate the association between serum adropin concentration and GDM. In a case-control study, conducted in 2013, 40 pregnant women with GDM and 40 healthy pregnant women (controls) were evaluated. Fasting serum adropin and lipid concentration were measured during 24th-28th weeks of gestation for both groups. These factors were compared between the two groups using independent sample t-test. There was a significant difference in adropin levels between the two groups and mean adropin levels were lower in GDM group (p: 0.016). There was no significant correlation between serum adropin levels and body mass index as well as fasting blood glucose (FBS) or serum lipid profile including high-density lipoprotein, low-density lipoprotein, cholesterol and triglyceride concentration (p > 0.05). There was a significant association between adropin concentration and GDM even after using regression model for removing confounding factors (odds ratio = 0.681). Low serum adropin concentration is associated with GDM in Iranian pregnant women.

ABSTRACT

BACKGROUND: This study aimed to assess the diagnostic capability of insulin surrogate measurements in identifying individuals with metabolic syndrome (MetS) and propose applicable indices derived from fasting values, particularly in large study populations. METHODS: Data were collected from the datasets of the Surveillance of Risk Factors of NCDs in Iran Study (STEPS). MetS was defined based on the National Cholesterol Education Program (NCEP) criteria. Various insulin surrogate indices, including Homeostasis Model Assessment (HOMA), Quantitative Insulin Sensitivity Check Index (QUICKI), Fasting glucose to insulin ratio (FGIR), Reynaud, Reciprocal insulin, McAuley, Metabolic Score for Insulin Resistance (METS-IR), Triglyceride-glucose index (TyG), TG/ HDL-C, TG/ BMI, and TG/ WC ratio were assessed. Receiver Operating Characteristic (ROC) curves were used to assess pathologic conditions and determine the optimal cut-off through the highest score of the Youden index. Also, Area Under the Curve (AUC) values were established for each index totally and according to sex, age, and BMI differences. RESULTS: The study population consisted of 373 individuals (49.9% women; 75.1% middle age, 39.1% obese, and 27.3% overweight), of whom 117 (31.4%) had MetS. The METS-IR (AUC: 0.856; 95% CI: 0.817-0.895), TG/ HDL-C (AUC: 0.820; 95% CI: 0.775-0.886), TyG (AUC: 0.808; 95% CI: 0.759-0.857), and McAuley (AUC: 0.804; 95% CI: 0.757-0.852) indices provided the greatest AUC respectively for detection of MetS. The values of AUC for all the indices were higher in men than women. This trend was consistent after data stratification based on BMI categories, middle age, and senile individuals. CONCLUSION: The present study indicated that indices of insulin, including METS-IR, TG/HDLC, TyG, and McAuley, have an equal or better capacity in determining the risk of MetS than HOMA-IR, are capable of identifying individuals with MetS and may provide a simple approach for identifying populations at risk of insulin resistance.

ABSTRACT

Background: The in vivo assessment of a novel compound is a pivotal step in the development of a new drug. In this study, we selected 1-(2-bromophenyl)-1,11-dihydro-3H-benzo[h]pyrano[3,2-c]quinoline-3,12(2H)-dione (2-BDBPQD), identified as an exemplary α-glucosidase inhibitor in preliminary in vitro assays, for further evaluation in an in vivo anti-diabetic context. Methods: The in vivo anti-diabetic effect of 2-BDBPQD was assessed using a streptozotocin (STZ)-induced diabetic Wistar rat model. Recognizing the relevance of lipid factors in diabetes, we also investigated the impact of this compound on the lipid profile of diabetic Wistar rats. In silico studies, encompassing docking studies and pharmacokinetic predictions of 2-BDBPQD, were conducted. Results: The results obtained indicated a significant reduction in blood glucose levels with 2-BDBPQD treatment compared to acarbose. However, no significant effects on the lipid profile were observed. In silico studies revealed that 2-BDBPQD interacted with key residues in the α-glucosidase active site and exhibited favorable pharmacokinetic properties. Conclusion: In summary, the study demonstrated the in vivo anti-hyperglycemic activity of 2-BDBPQD. Nevertheless, further in vivo evaluations are recommended to comprehensively assess its potential as a new drug for the treatment of diabetes.
