Introduction: Cardiovascular diseases (CVDs) are the leading cause of death in the world. Many modifiable risk factors have been reported to synergistically act in the development of CVDs. We aimed to compare the predictive power of anthropometric indices, as well as to provide the best cut-off point for these indicators in a large population of Iranian people for the prediction of CVDs and CVD risk factors. Methods: All the data used in the present study were obtained from Khuzestan comprehensive health study (KCHS). Anthropometric indices, including BMI (body mass index), WC (waist circumference), HC (hip circumference), WHR (waist-to-hip ratio), WHtR (waistto-height ratio), ABSI (a body shape index), as well as CVD risk factors [dyslipidaemia, abnormal blood pressure (BP), and hyperglycaemia] were recorded among 30 429 participants. Results: WHtR had the highest adjusted odds ratios amongst anthropometric indices for all the risk factors and CVDs. WC had the highest predictive power for dyslipidaemia and hyperglycaemia [area under the curve (AUC) = 0.622, 0.563; specificity 61%, 59%; sensitivity 69%, 60%; cut off point 87.95, 92.95 cm, respectively], while WHtR had the highest discriminatory power for abnormal BP (AUC = 0.585; specificity 60%; sensitivity 65%; cut-off point 0.575) and WHR tended to be the best predictor of CVDs (AUC = 0.527; specificity 58%; sensitivity 64%; cut-off point 0.915). Conclusion: In this study, we depicted a picture of the Iranian population in terms of anthropometric measurement and its association with CVD risk factors and CVDs. Different anthropometric indices showed different predictive power for CVD risk factors in the Iranian population. [ABSTRACT FROM AUTHOR]

Introduction: Metabolic syndrome (MetS) is a cluster of risk factors, mainly central obesity, insulin resistance, and dyslipidemia, leading to life-threatening cardiovascular diseases. The prevalence of MetS can vary based on different ethnicities and many cultural and lifestyle factors. We aimed to evaluate the prevalence of MetS and possible correlations with lifestyle-associated factors among different ethnicities in Khuzestan, Iran. Methods: This cross-sectional study was conducted in Khuzestan province of Iran, among 30, 504 participants aged 20-65 years, between October 2016 and November 2019. Data was collected through questionnaires along with anthropometric and biological measurements. The National Cholesterol Education Program Adult Treatment Panel III definition was used to estimate MetS prevalence. Results: Overall, 31.9% (95% CI 31.4-32.4) had MetS (34.2% [95% CI 33.3-35.1] among males; 30.7% [95% CI 30.0-31.3] among females [p < 0.001]). Central obesity, elevated fasting blood sugar levels, and dyslipidemia were the most common abnormalities among those with MetS. The risk of MetS was estimated to increase by age, male gender, residing in urban regions, lower educational levels, lower physical activity levels, lower sleep time, and a positive family history of diabetes mellitus (p < 0.001). Individuals of the Arab and Bakhtiary ethnicities had the highest and lowest risk of MetS, respectively. Conclusion: MetS prevalence varied among different ethnicities. Aging and some lifestyle-associated factors such as physical activity and sleep time were related to the isk of MetS. Raising awareness about risk factors of MetS would be of great value in setting new health policies to manage the rising trend of MetS. [ABSTRACT FROM AUTHOR]

Introduction: Irritable bowel syndrome (IBS) is a functional disease with no exact laboratory or imaging findings. IBS is more common in areas with a history of psychological trauma and war. This study aims to report the prevalence and possible determinants of IBS in southwestern Iran, an area with a notable history of war. Methods: We randomly enrolled 1849 permanent residents in 29 cities aged 20 to 65 years. A validated for Farsi version Rome III criteria and a questionnaire, including demographic data and health history, were administered to each subject. Participants who fulfilled the Rome III criteria were categorized into three groups: Diarrhea dominant (IBS-D), Constipation dominant (IBS-C), and Mixed type (IBS-M). Results: The total prevalence of IBS was 3.2%, with 70% of subjects being of Arab descent (P = 0.004). IBS was more common in females, singles, illiterate subjects, and people younger than 30 years; however, none of these differences were statistically significant. People with depression, anxiety, self-report of psychological disorders, and very low socioeconomic status had a significantly higher prevalence of IBS (P < 0.05). After multivariable logistic regression analysis, very low socioeconomic status had an independent role in IBS predictivity (OR: 2.28, 95% CI: 1.01–5.15). Conclusion: This study shows a higher prevalence of IBS symptoms in a population-based study in the region compared to counterparts in other regions of Iran. Considering the higher prevalence of self-reported psychological disorders, further studies are recommended to focus on the exact diagnosis of mental disorders and their influence on IBS.

BACKGROUND The appropriate dose of proton pump inhibitors for treatment of patients with upper (GI) bleeding remains controversial. This study compares high-dose versus low-dose intravenous proton pump inhibitor (PPI) infusion for prevention of GI bleeding complications. METHODS A total of 166 patients with bleeding peptic ulcers underwent therapeutic endoscopy using concomitant therapy by argon plasma coagulation (APC) and diluted epinephrine injection. Patients were randomly divided into two groups: high-dose pantoprazole (80 mg bolus, 8 mg per hour) and low-dose pantoprazole (40 mg bolus, 4 mg per hour) infused for three days. Initial outcomes were rebleeding, need for surgery, hemoglobin drop more than two units, and hospitalization for more than five days. Secondary outcome included mortality rate. RESULTS Overall, 166 patients (83 patients per group) enrolled in the study. The average age of patients in the high-dose group was 59.5±15.6 years and 52.3±13.3 years in the low-dose group (p=0.58). Males comprised 69.7% of patients. In the high-dose group, the mean number of units of transfused blood was 3.3±1.71 and in the low-dose group, it was 2.82±1.73 (p=0.50). There were 36 (43.37%) patients in the high-dose group and 40 (48.19%) in the low-dose group who were hospitalized for more than 5 days (p=0.53). Rebleeding was observed in 27 (32.53%) patients in the high-dose group and in 21 (25.30%) in the low-dose group (p=0.30). There were no significant differences observed in drop in hemoglobin of more than two units (p=0.15), mortality (p=0.99) and surgery (p=0.75) between the two groups. CONCLUSION For controlling peptic ulcer bleeding, there is no difference between high dose and low dose pantoprazole infusion [ABSTRACT FROM AUTHOR]

BACKGROUND Celiac disease presents with a wide spectrum of symptoms. This study clarifies different aspects of celiac disease along with the most common patterns of celiac presentation in Khuzestan Province, Iran. METHODS Patients’ information was obtained by evaluation of their files from the archives of the Khuzestan Celiac Society and records at gastroenterologists’ offices in this province. RESULTS Overall, there were 103 (40 males, 63 females) patients included in this study. Patients’ mean ages were 33 ± 11 years (males) and 31.6 ± 11.7 years (females). In terms of geographic distribution, 54.1% resided in the center of the province followed by 26.5% who were residents of the northern area. The rate of employment among men was 70.6% whereas it was 8.3% for women. In terms of education, 21.9% of men and 33.3% of women had academic educations. The rate of matrimony was 80.6% (n=29) for men, 65.4% (n=38) for women and 3.4% (n=2) who were divorced. Mean height was 164 ± 14 cm in men and 157.5 ± 10 cm in women. Mean BMI at the time of presentation was 22.7 in men and 22.6 in women. The most common gastrointestinal (GI) complaints in male patients were diarrhea (35%), reflux (20%), bloating (17.5%), abdominal pain (15%), vomiting (15%) and constipation (7.5%). Female patients experienced diarrhea (49.2%), abdominal pain (31.7%), bloating (31.7%), vomiting (19%), constipation (9.5%) and reflux (7.9%). The most common concomitant non-GI disorders among male patients were anemia (17.1%), thyroid disease (14.3%), and weight loss (14.3%); women experienced anemia (33.9%), thyroid disease (12.5%), and weight loss (7.1%). Approximately half of the patients exhibited symptoms for more than five years prior to diagnosis and 90% were diagnosed by gastroenterologists. Of these, 43% had normal endoscopy results. The most common serologic markers were anti-TTG (69.9%), anti-EMA (27.7%). CONCLUSION Physicians, prior to attributing patients’ symptoms to irritable bowel syndrome (IBS), should be aware that patients who present with long-term nonspecific symptoms might possibly have celiac disease. During endoscopy, the threshold for obtaining biopsies should be low. [ABSTRACT FROM AUTHOR]

Background: Upper endoscopy, as an important diagnostic and occasional therapeutic tool is invasive. Sedation of patients during the endoscopy procedure with minimal side effects could raise patient tolerability, allowing for ease and increased effectiveness of this procedure. Materials and Methods: In this study, 105 patients who were candidates for the upper endoscopy procedure were randomly divided into two groups: (A) midazolam (n=53) and (B) placebo (n=52). Group A patients received 5 mg of midazolam dissolved 5 cc distilled water and group B received 5 cc of distilled water, via an intra-nasal drip. After 40 to 45 minutes, the upper endoscopy was performed. During the endoscopy, patients were monitored and the endoscopy time, gag reflex stimulation, heart rate, arterial oxygen saturation (SPO2), amnesia and patient justification were recorded and compared. Results: The average age in group A was 39.3 years; for group B, it was 39.9 years. There were no statistically significant results for average endoscopy time (p=0.23), gag reflex stimulation (p=0.27), heart rate (p=0.09), SPO2 (p=0.49), amnesia (p=0.12), and patient justification (p= 0.1) between both groups. Conclusion: According to the results of this study, it seems that intra-nasal midazolam is not effective for patient sedation. This field needs additional evaluation. [ABSTRACT FROM AUTHOR]

Introduction: In 2017, the American College of Cardiology/ American Heart Association (ACC/AHA) provided a new guideline for hypertension prevention and management. We aimed to update the prevalence, awareness, control, and determinants of hypertension based on this guideline in Khuzestan province, southwest of Iran, and to estimate the number of people who are eligible for non-pharmacologic and pharmacologic intervention. Methods: This population-based cross-sectional study was conducted in Khuzestan, a large province in the southwest of Iran. Comprehensive information about the potential relating factors of hypertension was collected, blood pressure was measured, and anthropometric measurements were obtained. Moreover, the dietary pattern was evaluated in 2830 individuals, using a qualitative food frequency questionnaire. Results: Among 30, 506 participants, 30, 424 individuals aged 20-65 years were eligible for the study. In comparison with the previous guideline released by the Joint National Committee (JNC8), the prevalence of hypertension in Khuzestan dramatically increased from 15.81 to 42.85% after implementation of the ACC/AHA guideline, which was more dominant in the male population and the 45-54 age group. The sex and age adjustment of the hypertension prevalence was estimated to be 39.40%. The percentage of hypertension awareness, treatment, and control were 45.85%, 35.42%, and 59.63%, which dropped to 22.72%, 26.37%, and 28.94% after implementation of new guideline, respectively. Conclusion: In the ACC/AHA guideline, a higher number of individuals with the pre-hypertension condition were shifted into the hypertension category and the level of awareness, treatment, and control were dramatically decreased, which highlight a great need to expand the public health infrastructure for further managing the substantial increased burden on healthcare system. However, further studies with population over 65 years are required to estimate the eligibility for antihypertensive treatment in this province after implementation of new guideline.
