Tania Dehesh,1 Paria Dehesh,2 Mohammad Hossein Gozashti31Department of Biostatistics and Epidemiology, School of Public Health, Kerman University of Medical Sciences, Kerman, Iran; 2Graduated of Veterinary Medicine Faculty, Shahid Bahonar University of Kerman, Kerman, Iran; 3Department of Endocrinology, Kerman University of Medical Sciences, Kerman, IranPurpose: In the past few decades, an increase in the life span of the population has caused more people to experience chronic diseases, such as type 2 diabetes. Since chronic diseases influence the whole life of patients and do not have a specific remedy, improving their health-related quality of life (HRQoL) becomes more important. The aim of the present study was to investigate the metabolic variables that influenced HRQoL questionnaire scores most significantly among patients with type 2 diabetes.Patients and methods: The population of this cross-sectional study included 163 patients with type 2 diabetes and 214 healthy people who were asked to complete the HRQoL questionnaire, and their metabolic blood variables were recorded simultaneously. The effects of metabolic variables and some other demographic ones on two main scales of HRQoL, Mental Component Summary (MCS) and Physical Component Summary (PCS), were evaluated using multivariate regression.Results: Multivariate regression analysis showed that PCS score was most negatively influenced by cigarette smoking (P=0.009, β-15.761), maximum blood pressure (P=0.008, β=−0.108), minimum blood pressure (P=0.009, β=−0.039), low-density lipoprotein cholesterol (P=0.008, β=−0.721), cholesterol (P=0.006, β=−0.648), HbA1c (P=0.004, β=–0.878), FBS (p=0.006, β=−0.769), and body mass index (BMI) (P=0.034, β=–0.287). The MCS score was influenced positively by smoking cigarettes (P=0.041, β=13.032), gender (P=0.018, β=15.633), and BMI (P=0.048, β=−0.088). Men had a higher MCS score compared to women.Conclusion: The HRQoL questionnaire (as a concept of health) score could be improved by controlling the variation of some metabolic variables in patients with type 2 diabetes. Some metabolic variables could be the main causes of a decrease in physical and mental HRQoL among patients with type 2 diabetes.Keywords: quality of life, SF-36 questionnaire, metabolic variables

People with metabolically healthy obesity (MHO) are at risk of developing cardiometabolic diseases. We investigated the prevalence of MHO and factors influencing its transition into a metabolically unhealthy state (MUS). This study was conducted as part of the Kerman Coronary Artery Disease Risk Factor Study (KERCADRS). From 2014 to 2018, 9997 people were evaluated. The obesity and metabolic status of the MHO participants were re-examined after 5 years of their initial participation in the study. Out of 347 MHO, 238 individuals were accessed at follow-up. Twenty-nine (12.2%) had metabolic unhealthy normal weight (MUNW), 169 (71.0%) had metabolic unhealthy obesity (MUO), and the others had healthy metabolic state. Among age, total cholesterol, diastolic blood pressure and triglyceride (TG) variables, the baseline serum TG level was associated with a significant increase in the risk of developing MUS during 5 years (p <.05). The TG level optimal cut-off point for predicting the development into MUS was 107 mg/dL with 62.1% sensitivity and 77.5% specificity (AUC = 0.734, p <.001). A high percentage of MHO people transit into MUS during 5 years. A TG level higher than 107 mg/dL can help to identify people at a higher risk of developing into MUS., (© 2024 World Obesity Federation.)

Introduction: Diabetes is a disease with high prevalence and causes heavy economic burden. Mental and physical health are tied together and their interaction determines one's health or sickness. Early maladaptive schemas (EMSs) are suitable indicators of mental health. We investigated the association between EMSs and glycaemic control in type 2 diabetes mellitus (T2DM) patients., Methods: We conducted a cross-sectional study in 2021 on 150 patients with T2DM. We used two questionnaires a demographic data questionnaire, and a Young Schema Questionnaire 2 - Short Form for gathering the data. We also performed laboratory tests on our participants and used the results of fasting blood sugar and haemoglobin A 1 c to evaluate glycaemic control., Results: Most of our participants were females (66%). Most of our patients were 41-60 years old (54%). There were only three single participants, and 86.6% of our individuals did not have a university degree. Total mean ± SD for EMSs score was 192.45 ± 55.66; self-sacrifice (19.09 ± 4.64) and defectiveness/shame (8.72 ± 4.45) had the highest and lowest EMSs scores, respectively. None of the demographic data had any significant impact on EMSs scores or glycaemic control, but generally, younger patients with higher levels of education had better glycaemic control. Participants with higher scores for defectiveness/shame and insufficient self-control had significantly worse glycaemic control., Conclusion: Mental and physical health are tied together, and paying attention to psychological aspects in prevention and management of physical disorders is crucial. EMSs, especially defectiveness/shame and insufficient self-control are associated with glycaemic control of T2DM patients., (© 2023 The Authors.

Background and Purpose: The lack of timely foot care among individuals with diabetics often lead to ulceration followed by infection and amputation. This study aimed to evaluate the foot self-care status and foot screening practices among patients with type 2 diabetes in various cities across Iran., Methods: The cross-sectional descriptive study was performed on patients with type 2 diabetes in 10 main cities of Iran. The information about demographic and lifestyle factors, diabetes history, and diabetic foot self-care (DFSQ) was assessed. Additionally, the neurological and vascular condition of the foot were screened by Inlow's 60-Second Screen., Results: The study included 1094 diabetic patients with, with a majority being female (64.8%) and married (92.5%). The average age of the participants was 57.6 ± 10.21 (mean ± SD), and the mean duration of diabetes was 11.56 ± 7.41 years. Based on Inlow's 60-Second Screen criteria, 58% of the patients should undergo yearly foot ulcer screening, 47% exhibited peripheral neuropathy, and 37% were found to have inappropriate footwear., Conclusion: The high prevalence of peripheral neuropathy observed in approximately half of the participants across different regions of Iran underscores the importance of continuous patient education regarding foot care and appropriate footwear. Furthermore, regular foot ulcer screenings, following the recommended intervals outlined in Inlow's screening protocol, should be implemented to effectively manage diabetic foot complications., (© 2023.

Background: Atherosclerosis has an essential role in causing cardiovascular diseases. Various factors affect the risk of coronary artery atherosclerosis, and the increase in the carotid intima-media thickness (CIMT) is a primary marker for detecting atherosclerotic changes in the artery wall. Since opioid use is one of the leading social and health problems in many countries, this study aimed to detect the factors influencing the increase in CIMT in opium consumers., Methods: This cross-sectional study was conducted on 350 participants of the phase 2 of the KERCADRS cohort study who visited Besat clinic in Kerman and were divided into addicted and non-addicted groups. The participants in both groups underwent carotid artery ultrasound, and the Philips IU22 ultrasound machine was used to measure the CIMT., Findings: The mean age of the participants was 42.28±12.58 in the addicted group and 35.99±15.38 in the non-addicted group ( P =0.001). CIMT was similar in the two groups ( P =0.170). Moreover, CIMT had a significant positive correlation with age, waist circumference, systolic blood pressure (SBP), body mass index (BMI), fasting plasma glucose (FPG), and triglyceride in both addicted and non-addicted groups. Age, weight, waist circumference, SBP, and BMI in the multivariate model were significant determinants of CIMT in the addicted group., Conclusion: The results revealed that age, weight, waist circumference, SBP, and BMI were the factors influencing intima thickness in opium consumers, and no significant relationship was observed between addiction to opium and CIMT., Competing Interests: Competing Interests The authors have no conflict of interest., (© 2023 Kerman University of Medical Sciences.)

Background: Metabolic syndrome (MetS) is a global public health concern. Chronic inflammation plays a role in MetS; haematological inflammatory parameters can be used as MetS predicting factors., Objective: Hereditary and environmental factors play an important role in the development of MetS. This study aimed to determine the relationship between haematological parameters and MetS in the adult population of southeastern Iran, Kerman., Methods: This cross-sectional study was a sub-analysis of 1033 subjects who participated in the second phase of the Kerman Coronary Artery Disease Risk Factor Study (KERCADRS). Metabolic syndrome was diagnosed according to Adult Treatment Panel III (ATP III) definition. Pearson correlation coefficient was used to investigate the relationship between haematological parameters with age and components of metabolic syndrome. The role of WBC, neutrophil, lymphocyte and monocyte in predicting metabolic syndrome was evaluated using the receiver operating characteristic (ROC) curve., Results: White blood cell (WBC) and its subcomponent cells count, red cell distribution width (RDW), monocyte to HDL ratio (MHR) and Neutrophil to HDL ratio (NHR) had a significant positive correlation with the severity of MetS. The cut-off value of WBC was 6.1 (×10 3 /μL), the sensitivity was 70%, the specificity was 52.9% for females, the cut-off value of WBC was 6.3 (×10 3 /μL), the sensitivity was 68.2% and the specificity was 46.7%, for males., Conclusion: WBC and its subcomponent count, RDW, MHR and NHR parameters are valuable biomarkers for further risk appraisal of MetS in adults. These markers are helpful in early diagnoses of individuals with MetS., (© 2023 The Authors. Endocrinology, Diabetes & Metabolism published by John Wiley & Sons Ltd.)

The present investigation was conducted to evaluate the vascular-toxicity of empagliflozin (EMP) in embryonic vasculature. Firstly, the vascular-toxicity of the drug as well as its interaction with apoptotic regulator proteins was predicted via in silico approach. In the next step, the apoptotic-signaling pathway in embryonic vasculature was evaluated using a chick's YSM model. In silico simulation confirmed vascular-toxicity of EMP. There was also an accurate affinity between EMP, Bax and Bcl-2 (-7.9 kcal/mol). Molecular dynamics assay revealed complex stability in the human body conditions. Furthermore, EMP is suggested to alter Bcl-2 more than BAX. Morphometric quantification of the vessels showed that the apoptotic activity of EMP in embryonic vasculature was related to a marked reduction in vessel area, vessel diameter and mean capillary area. Based on the qPCR and immunohistochemistry assays, enhanced expression level of BAX and reduced expression level of Bcl-2 confirmed apoptotic responses in the vessels of the YSM. We observed that induction of an apoptotic signal can cause the embryonic defect of the vascular system following EMP treatment. The acquired data also raised suspicions that alteration in apoptotic genes and proteins in the vasculature are two critical pathways in vascular-toxicity of EMP., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Mosallanejad, Mahmoodi, Tavakkoli, Khosravi, Salarkia, Keyhani, Dabiri, Gozashti, Pardakhty, Khodabandehloo and Pourghadamyari.)

Aims: This study aimed to determine a parameter to more easily diagnose metabolic syndrome and predict its probability of occurrence in high-risk individuals., Methods: In this cross-sectional study, data related to the study population in the Kerman Coronary Artery Disease Risk Factor Study (KERCADRS) were examined. Subjects were divided into two groups with and without metabolic syndrome, and the relevant factors such as the ratios of uric acid to high-density lipoprotein (HDL) (UHR) in these two groups were compared, and the best cut-off point was determined., Results: Data related to 817 people including 96 people with metabolic syndrome and 721 people without metabolic syndrome were analysed. The mean UHR was significantly higher in patients with metabolic syndrome (14.76 ± 6.33%) compared with those without metabolic syndrome (10.0 ± 3.10%) (p < .001). People with high UHR are 2.9 times more at risk of metabolic syndrome and the best cut-off point was 9.50% with 86% sensitivity and 55% specificity., Conclusions: According to our study, UHR is also helpful in diagnosing metabolic syndrome and can also be used to screen people at risk for metabolic syndrome., (© 2021 The Authors.

Introduction: Thyroid cancer is the most common endocrine malignancy, and it has the fastest increase rate in incidence in both sexes, with a yearly increase of 3% over the last decade. Thyroid-stimulating hormone (TSH) is the main driver for the thyroid gland to produce thyroid hormone. The main purpose of this study was to assess the relationship between serum TSH level and the stage of malignancy in patients with differentiated thyroid cancer., Methods: This cross-sectional study was performed on 77 patients with thyroid cancer. The demographic characteristics, TSH level and stage of malignancy were recorded for all patients in the data collection form. The data analysis was conducted by descriptive statistics using SPSS 20.0 software., Results: The results show a significant relationship ( p -value = .025) between the malignancy stage and serum TSH level. The mean TSH level in patients of stage 3 (5.70 ± 2.03) was significantly higher than patients in stage 2 (2.58 ± 0.52) and stage 1 (2.33 ± 0.28). No significant relationship was observed between the age of patients and serum TSH level. Although the mean serum TSH level in men (3.61 ± 0.98) was higher than in women (2.52 ± 0.25), the difference was not statistically significant., Conclusions: According to the results of this study, serum TSH level can be considered as a predictor of the stage of differentiated thyroid cancer. Therefore, it can be used to predict the likelihood of cancer and improve the outcome and extent of thyroidectomy in patients with thyroid cancer., Competing Interests: The authors declare that they have no conflict of interests., (© 2021 The Authors.

Background: The objective of this study was to compare various lipid ratios for detection of metabolic syndrome (MetS) in the Iranian general population., Methods: This cross-sectional study involved 5677 subjects aged ≥18 years from the general population in Kerman, Iran. Associations between lipid ratio quartiles and MetS were analyzed using logistic regression models. The areas under receiver operating characteristic (ROC) was calculated to determine the accuracy of lipid ratios in predicting MetS., Results: The adjusted chance of having MetS across quartiles of all lipid ratios had an increasing significant pattern (P < 0.0001). The area under the curves of triglyceride/high-density-lipoprotein-cholesterol (TG/HDL-C) ratio was 0.85 (95% CI = 0.84-0.87) in men and 0.85 (95% CI = 0.84-0.86) in women, of total cholesterol (TC)/HDL-C ratio was 0.79 (95% CI = 0.77-0.81) in men and 0.79 (95% CI = 0.77-0.81) in women and of low-density-lipoprotein cholesterol (LDL-C)/HDL-C ratio was 0.73 (95% CI = 0.71-0.75) in men and 0.74 (95% CI = 0.72-0.76) in women., Conclusion: Our results indicate that the TG/HDL-C Ratio is a better marker than the LDL-C/HDL-C ratio and the TC/HDL-C ratio for identifying MetS in the Iranian population and could be used in clinical practice., (© 2018 The Author(s).

Background: Several components of metabolic syndrome (MetS) facilitate its diagnosis, including abdominal obesity, hyperlipidemia, high blood pressure, and insulin resistance. The production of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) seem to be associated with MetS components. The aim of this study was to evaluate the correlation between IL-6 and TNF-α serum levels with MetS and its components., Methods: This case-control study investigated 250 subjects, comprising 125 healthy controls from the Kerman Blood Transfusion Organization and 125 MetS patients. Serum IL-6 and TNF-α levels were measured using the enzyme-linked immunosorbent assay (ELISA)., Results: Serum IL-6 and TNF-α levels were greater in MetS patients than in controls. However, no correlation was observed between MetS components and IL-6 or TNF-α serum levels., Conclusion: Patients with MetS had significantly greater serum IL-6 and TNF-α levels than the controls, supporting the evidence that inflammation plays an important role in the immunopathogenesis of the disease. Additionally, IL-6 and TNF-α serum levels may predict MetS. The lack of association between IL-6 and TNF-α serum levels and MetS components remains to be investigated by further research.

Background: Osteoporosis and osteopenia are the most common metabolic bone diseases making the patients vulnerable to bone fragility and fracture. In this study, the association of opium consumption and osteoporosis adjusted for other risk factors was studied., Methods: In this cross-sectional study, 619 cases including 73 men and 546 women referred to densitometry center in Kerman, Iran, were studied. Demographic information, history of opium consumption, medications, and other risk factors were collected using a structured questionnaire., Findings: In a univariate analysis, opium consumption, aging, and having a body mass index (BMI) lower than 24 accompanied an increased chance of osteoporosis, while taking physical exercises on a daily basis reduces the chance of osteoporosis. Through multivariable analysis, the two variables of age group and BMI group turned out to be of significance; that is, the chance of osteoporosis or osteopenia in the age group of higher than 60 years and 45-60 years being placed in one of the levels of osteoporosis or osteopenia was 4.9 and 3.1 times higher than the age groups lower than 45 years, respectively, after being adjusted to the other variables., Conclusion: Considering the results of this study, though the risk of bone density reduction in the individuals consuming opium was higher, due to the disparity between opium consumption in the two sexes, the difference was not significant between the two groups, and it is proposed that studies on larger samples and in the both sexes be conducted to determine the impacts of opium on the bone density.

Sleep disturbances have been shown to be associated with diabetes control, but the relation between planned wakings or napping with glycemic indices has not been evaluated yet. This study evaluated the relation between sleep quality, duration, and pattern, including daytime napping of people with diabetes and their glycemic control. A cross-sectional correlation research design was used for this study. We enrolled 118 people with type 2 diabetes receiving oral agents without major complications at the Shahid Bahonar Center, Kerman. The age, weight, height, serum HbA1c, as well as other glycemic indices and lipid profile were measured. BMI was also calculated. All participants were requested to fill in the Pittsburgh Sleep Quality Index (PSQI) questionnaire to evaluate their sleep quality. In addition, they were inquired about their sleep schedule during day and night. Pearson correlation and multiple regression analyses were conducted to examine the correlation between HbA1c and sleep pattern variables. The variables were also compared between participants with or without napping using t-test. All analyses were performed with the SPSS version 19 (SPSS, Chicago, IL, USA). The mean age was 58±11 years and mean HbA1c (%) was 7.8±11 (62±13 mmol/mol). Sleep duration and the number of sleep segments significantly predicted HbA1c (F (2,114)=5.232, P=0.007, R2=0.084). A one-hour increment in sleep duration was associated with a 0.174% (1.4 mmol/mol) decrement in HbA1c. PSQI score did not contribute to the regression model. Moreover, participants who napped (66%) had a lower HbA1c (7.6±1) compared to others (8.1±1.3) (P=0.04). We concluded that napping and segmented sleep are associated with a better glycemic control in type 2 diabetes and there is a linear correlation between sleep duration and better glycemic control.

Background: Iran is one of the major consumers of opium and opiate substances in the world. Addiction has become a very important issue in the 21 st century and an urgent one in Iran. The consumption of this substance leaves a variety of impacts on the human body. The goal of this study is to investigate the changes of the biochemical parameters derived from opiate substances in addicts during their treatment., Methods: This is a cross-sectional research that focused on 40 individuals dependent on the consumption of opium. Their blood samples were taken before and during treatment, and their fasting blood sugar (FBS), sodium, calcium, phosphorus, creatinine, urea, uric acid, total protein, triglycerides, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and total cholesterol were measured. Data were analyzed by SPSS using paired t-test., Findings: The results showed that serum uric acid, LDL, cholesterol, and the total protein levels significantly decreased during the treatment in comparison with the time before the treatment (P < 0.050). Yet, the serum fasting glucose, urea, creatinine, HDL, triglycerides, calcium, phosphorous, sodium, and potassium showed no significant change the time prior and during the treatment., Conclusion: Given the findings of the analysis, opium addiction has a number of destructive impacts on the lipid profile and uric acid. In addition, the level of total protein decreased during the treatment.

Introduction: Clinical education is one of the most important components of the resource generation function of health systems, and it has a very important role in graduates' competency with respect to effective, practical education. This study aimed to assess the quality of clinical services in Kerman's teaching hospitals located in southeastern Iran., Methods: This cross-sectional study was conducted in 2011 on 303 medical students at different levels of medical education at Kerman's teaching hospitals. A modified SERVQUAL instrument was used to collect the data after its validity and reliability were checked. The data were analyzed by SPSS 18.0 using the paired t-test, Kruskal-Wallis, and post hoc tests, when appropriate., Results: In all five dimensions of quality, gaps were observed between students' perceptions and expectations as follows: Assurance (mean = -1.18), Responsiveness (-1.56), Empathy (-1.4), Reliability (-1.27), and Tangibles (-1.21). There was a significant difference between the quality perceptions and expectations of the medical students (p < 0.001). A significant difference was observed between three educational levels, including externships, internships, and assistantships regarding the dimensions of the quality gaps (p < 0.001)., Conclusion: The clinical services provided by teaching hospitals in the study did not meet the students' expectations at any of the three educational levels. As we precisely assessed the dimensions and items that had the higher quality gaps, it was apparent that, for most part, clinical education officials could improve the quality by designing interventions, which would not be very difficult to do.

Background: Many of lay person believe that opium lowers blood glucose. However some studies show the opposite results. In this study, we tried to evaluate the effect of opium on blood glucose and insulin resistance., Methods: This comparative study including 53 addicts in case groups who used opium just in the form of smoking and 55 non-addicts in a control group, took part in the study, after proving not to be opium users. After taking blood samples, their fasting blood glucose (FBG), fasting blood insulin and lipid profiles were evaluated. Furthermore, insulin resistance index was analyzed via the homeostatic model assessment of insulin resistance (HOMA-IR) formula with the cut-off points of 7.2 and 7.1., Findings: Age and gender were not significantly different between the groups. There was no significant difference regarding the prevalence of insulin resistance between the two groups, according to the cut-off points of 7.1 and 7.2 (P = 0.196 and P = 0.248, respectively). Mean insulin resistance index was not significantly different between the two groups (P = 0.325). In the case group, fasting blood insulin was considerably lower (P = 0.025) and fasting blood sugar (FBS) was significantly higher (P = 0.016) than the control group., Conclusion: According to the level of insulin and FBS in addicts, it does not seem that opium has a significant effect on reducing the blood glucose and insulin resistance.

Background: Atherosclerotic disorders, hypertension and lipid profile alterations are of a lower prevalence in patients with minor beta thalassemia. On the other hand, nowadays, metabolic syndrome is considered as one of the major risk factors of developing cardiovascular diseases. Therefore, the present study was performed to determine the prevalence of metabolic syndrome in patients with minor beta thalassemia., Methods: In this case-control study, body length, weight and waist circumference, blood pressure, fasting blood sugar [FBS], triglyceride, cholesterol, HDL, and LDL levels were determined in 150 patients with minor beta thalassemia and 300 healthy individuals as control group [matched based on age and sex]. The prevalence of metabolic syndrome was calculated based on ATPIII criteria. Data were analyzed through SPSS16 software package., Results: The prevalence of metabolic syndrome was 12.7% in the thalassemia group and 36.7% in the control group [p < 0.0001]. In the patient group, 3 ones [8.3%] of those with metabolic syndrome were male and 16 ones [14%] were female [p = 0.5]. Mean age of patients with metabolic syndrome was 39.4 ± 8.5 years and mean age of those without metabolic syndrome was 36.4 ± 7.8 years [p = 0.1]. Mean BMI of those with metabolic syndrome was 31.3 ± 4.1 kg/m(2) and that of those without metabolic syndrome was 24.2 ± 4.4 kg/m(2) [p < 0.0001]., Conclusions: The obtained results show lower prevalence of metabolic syndrome in patients with minor thalassemia. Moreover, the prevalence of metabolic syndrome in patients with minor thalassemia showed no relationship with sex and age and these patients had just higher BMI.

Background: Due to this belief that opium may have beneficial effects on diabetes or cardiovascular risk factors, the present study aimed to assess the potential and possible effects of opium consumption on diabetes control and some cardiovascular risk factors in diabetic patients., Methods: This study enrolled 374 diabetic subjects from diabetes care centers in Kerman, Iran, including opium user group (n = 179) and a non-opium user group (n = 195). The data were collected through a questionnaire completed by interviewing, physical examination and laboratory assessment., Findings: Opium did not show any statistically significant effect on blood glucose, glycated hemoglobin (HbA1C), fasting blood sugar (FBS), low-density lipoprotein (LDL) and diastolic blood pressure. However, systolic blood pressure (SBP) and prevalence of high SBP were significantly higher in opium user group (P < 0.050). In addition, lower serum high-density lipoprotein (HDL) and frequency of lower HDL was significantly higher in opium user group (P < 0.001)., Conclusion: According to this study, opium does not seem to have beneficial effects on diabetes control or cardiovascular risk factors. Therefore, it would not be advisable to consume opium as an anti-diabetes or cardioprotective agent.

Background: A number of abnormalities has been identified among drug addicted users especially heroin addicts. However, there are a few studies to assess the opium effects on thyroid hormones. the aim of the present study is to investigate the effect of opium on the thyroid function tests., Method: In this case-control, 50 male addicts, aged 20-50 years, with history of addiction to opium lasting more than two years, and 50 male non-addicts as control group were randomly selected. 10 cc blood sample was taken for measurements of TSH, total T4 and T3, free T4 and T3, and T3 resin uptake (T3RU) and 50 cc urine sample for opium testing., Results: The univariate analysis revealed that there was not a significant association between opium and serum levels of T4 and TSH, but compared with control group, a slight increase in total T3 and a decrease in T3RU were observed among addicts (P < 0.05). In multivariate analysis, opium was also found to exert a lowering effect on serum free T4 level after adjusting of age and cigarette smoking (P < 0.05)., Conclusion: The findings of the present study demonstrated that opium can influence on thyroid function by increasing total T3 and decreasing T3RU and free T4 levels.

Objectives: Metabolic syndrome is a determining indicator of cardiovascular diseases and diabetes. Abdominal obesity, determined by measuring waist circumference, is one of the most important criteria for diagnosing this syndrome. This criterion varies between men and women and among different races. The present study aims at the assessment of the sensitivity and specificity of the commonly used cut off point of waist circumference, and the estimation of the most suitable cut off point of waist circumference for the diagnosis of metabolic syndrome in the urban society of Kerman., Methods: 5332 subjects consisting of 2966 women and 2366 men, 20 years old and above were studied in a population based, cross sectional study. Waist circumference, blood pressure, blood sugar, and blood lipids were measured. People with at least two of the NCEP ATP III criteria - high blood pressure (BP>130/80), high triglycerides (TG>150), high glucose (FBG>100) and low HDL (HDL<40 in men and <50 in women) - were taken as population at risk. ROC analysis was used for determining the most suitable cut off point of waist circumference. The prevalence of metabolic syndrome was then assessed based on IDF, NCEP criteria and the proposed criterion, and agreement among the three methods in diagnosing people suffering from metabolic syndrome was examined., Results: The average±standard deviation of waist circumference in women and in men was 83.90±12.55 and 87.99±11.94 cm respectively. The most suitable cut off point of waist circumference for metabolic syndrome diagnosis was 86 in women and 89 in men. These circumferences had the highest specificity and sensitivity. The prevalence of metabolic syndrome in IDF, NCPE, and the proposed criterion was 30.4%, 27.7%, and 35.2% respectively. The new criterion and the NCEP criterion achieved the highest agreement (kappa factor=83%)., Conclusion: The cuts off point of waist circumference in men and women are close. It is possible, then, to determine a common cut off point of waist circumference for both in Iran. Therefore, the cut point of 90-cm of waist circumference proposed by the National Obesity Committee seems to be appropriate for the Iranian society. These clinical findings should nevertheless be verified by simulation., (Copyright © 2013 Diabetes India. Published by Elsevier Ltd. All rights reserved.)

Noise is one of the most harmful agents in the workplace. In addition to the adverse effects of noise on the auditory system, as a stressor it may cause increased blood pressure, cardiovascular disease, anxiety, and impaired secretion of hormones. The purpose of this study was to evaluate changes in urinary catecholamines in workers exposed to industrial noise. This is an experimental study of the workers at the smelter section of Sarcheshmeh Copper Industries done on two separate days. During the first day, urine samples from 20 workers who did not use any hearing protection device, were collected during an 8-h work shift and on the second day the same was done but they were asked to use earplugs. Also 20 people were selected as a control group from people who were not exposed to noise at work. Urinary catecholamine levels were measured with ELISA kits. The mean urinary epinephrine and norepinephrine levels in the workers (without earplugs) was respectively 8.69 and 35.56 μg/8h on the first day and on the second day (with earplugs) dropped to 6.45 and 30.95 μg/8h. Noise reduction by earplugs led to almost significant reductions in urinary epinephrine (p = 0.05) and significant reductions in norepinephrine (p = 0.02). The results showed that with noise reduction the urinary excretion of stress hormones, especially norepinephrine significantly decreases and workers are probably less prone to stress-related disorders.

Background: Polycystic ovary syndrome (PCOS) causes an increased risk of metabolic cardiovascular syndrome. Also, cystatin C serum levels are associated with the risk of cardiovascular events in metabolic syndrome patients., Objective: To investigate the relationship between cystatin C in PCOS patients., Materials and Methods: 35 women with PCOS were compared to 35 women with healthy matched age and body mass index. They all underwent tests to determine plasma levels of C-reactive protein (CRP), cystatin C, lipid profile and apo-lipoprotein. Blood pressure and demographic variables of each subject were obtained., Results: Systolic and diastolic blood pressure were higher in PCOS patients compared to control group. Triglyceride and low-density lipoprotein cholesterol levels were higher in PCOS; contrariwise, high-density lipoprotein was lower from that of healthy volunteers. Cystatin and CRP levels were significantly higher in patients with PCOS in comparison with healthy subjects (p<0.0001). Among measured determinants, only PCOS status was independently associated with cystatin C., Conclusion: Cystatin C was positively correlated with PCOS status concentrations but not with systolic and diastolic blood pressure, or any of the lipid profile variables or demographic characteristics. Indeed, no correlation was found between cystatin C and CRP levels. Therefore, cystatin C might be related to PCOS beyond its use as a marker of the renal function.

Background: Drug abuse is one of the most important public health problems worldwide as in Iran. The aim of present study was to determine whether opium addiction can affect bone mineral density or not., Methods: Fifty opium addicted and 50 non-addicted volunteer men aged between 25-45 were enrolled. The subjects with positive history of other osteoporosis risk factors were excluded. The vertebral bone density and potential confounders (age, cigarette smoking and body mass index) were measured in all subjects., Results: Twenty six percent of non-addicted vs. 56% of addicted subjects had vertebral osteopenia. According to adjusted ORs, addiction to opium (OR: 3.08, CI95% 1.20-7.92) and age (OR: 1.11 CI95% 1.03-1.20) were significantly related to vertebral bone loss., Conclusion: Opium addicted patients were more susceptible to bone loss than non-addicted individuals. So,early screening and conducting prevention programs should be taken into consideration for this high risk group.

MEN-1 is an autosomal dominant familial cancer syndrome characterized by involvement of parathyroid, enteropancreatic endocrine tissues and the anterior pituitary gland. Malignant insulinomas are rare, and therefore, there are few data regarding their clinical presentation and long-term prognosis. In this report we present a large family with malignant insulinoma and hyperparathyroidism with MEN-1 gene mutation analysis. A large family (three generations) with several members affected were evaluated for clinical and biochemical characteristic of MEN-1 syndrome. Genetic analysis for MEN1 gene was carried out in all family members using PCR amplification of coding regions followed by direct sequencing. In three brothers that presented with hypoglycemia, insulinoma was confirmed and two were malignant according to pathology and surgery report. Two of them had hyperparathyroidism too. Mutation screening revealed the presence of a two nucleotide deletion in the exon 2 (c199&#95;200del2). In the current study, the deletion happens early in the sequence, and obviously results in a non-functional gene product. However, it will be helpful to further examine somatic mutations and other genetic markers for a more precise study of genotype-phenotype correlation.

Hyperglycemic crises of diabetic ketoacidosis and nonketotic hyperglycemia are associated with elevation of counterregulatory hormones and proinflammatory cytokines, markers of lipid peroxidation, and oxidative stress. To investigate if other conditions besides hyperglycemia could evoke such a prompt increase in cytokine levels, lipid peroxidation, and oxidative stress markers, we induced hypoglycemic stress by standard insulin tolerance test and measured proinflammatory cytokines, markers of lipid peroxidation, reactive oxygen species (ROS), and counterregulatory hormones. Insulin tolerance test was performed in 13 healthy male subjects with no history of infection, cardiovascular risk factors, or abnormal glucose. At baseline and at 30, 45, 60, 120, and 240 minutes after insulin injection, the following parameters were measured: glucose, cortisol, corticotropin, epinephrine (EP), norepinephrine (NE), growth hormone, tumor necrosis factor (TNF)-alpha, interleukin (IL) 1beta, IL-6, IL-8, free fatty acids, white blood cells, lipid peroxidation markers by thiobarbituric acid assay, and ROS by dichlorofluorescein method. The peak value of white blood cell count at 120 minutes was significantly associated with the peak values of NE at 30 minutes and cortisol at 60 minutes. By comparing the area under the curve of measured parameters, EP emerged as significant predictor of TNF-alpha (P = .05) and IL-8 (P = .027). Cortisol emerged as predictor of IL-1beta significantly (P = .05). Corticotropin predicted area under the curve of IL-6 with borderline significance (P = .06). In the present study, insulin-induced hypoglycemia in nondiabetic male subjects is associated with increased proinflammatory cytokines (TNF-alpha, IL-1beta, IL-6, and IL-8), markers of lipid peroxidation, ROS, and leukocytosis. Elevations of NE, EP, corticotropin, and cortisol in hypoglycaemia are associated with the elevation of the proinflammatory cytokines and leukocytosis.
