RESUMO
BACKGROUND: Waist circumference (WC), or waist-to-hip ratio (WHR), potentially offers a more accurate reflection of intra-abdominal fat accumulation and could serve as a superior predictor of type 2 diabetes mellitus (T2DM) risk compared to BMI. The current study investigated the relationship between WHR and its influencing factors among diabetes patients enrolled in the Prospective Epidemiological Research Studies in Iran (PERSIAN) Guilan Cohort study (PGCS). METHOD: In this cross-sectional study of 10,520 participants, 2,531 had T2DM. Waist and hip circumference, body mass index (BMI), underlying diseases, and demographical data of participants were recorded. Also, fasting blood sugar (FBS), low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides (TG) were assessed. All data was analyzed using SPSS version 16; the significant level was < 0.05. RESULTS: The mean age of participants was 51.52 ± 8.90 years, and 39.9% had a BMI between 25 and 30 kg/m2. The prevalence of diabetes was 24.1% (n = 2531). About 7628 (72.5%) individuals had abnormal WHR, and 2072 (19.7%) were diabetics. Among patients with diabetes, abnormal WHR was significantly associated with age over 50, female gender, higher BMI, and lower LDL (P < 0.05). CONCLUSION: The study showed a higher prevalence of abnormal WHR in diabetic patients. Abnormal WHR in patients with diabetes was significantly associated with age, gender, and BMI.

Objective: The purpose of this study is to evaluate the association between elevated serum liver enzymes and Metabolic Syndrome (MetS) in Prospective Epidemiological Research Studies of the Iranian Adults (PERSIAN) Guilan Cohort Study (PGCS) population. Methods: This cross-sectional study involved 10,519 individuals between the ages of 35 and 70 enrolled in the PGCS. The gathered data encompassed demographic information, anthropometric measurements, blood pressure, and biochemical indicators. MetS was defined by the National Cholesterol Education Program-Adult Treatment Panel III criteria (NCEP-ATP III). The associations between elevated liver enzymes and MetS were examined using logistic regression analysis. Odds ratio (OR) and 95 % confidence interval (CI) were calculated. Results: The prevalence of MetS was 41.8 %, and the prevalence of elevated alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), and alkaline phosphatase (ALP) were 19.4, 4.6, 11.6, and 5.1 %, respectively. In the unadjusted model, elevated ALT, AST, and GGT were associated with increased odds of MetS (OR = 1.55, 95 % CI: 1.41-1.71; OR = 1.29, 95 % CI: 1.07-1.55, and OR = 1.90, 95 % CI: 1.69-2.14, respectively). These associations remained significant for ALT and GGT after adjustment for some demographic and clinical characteristics (aOR = 1.31, 95 % CI: 1.17-1.46 and aOR = 1.30, 95 % CI: 1.14-1.49, respectively). In addition, the odds of MetS increased with the number of elevated liver enzymes, up to almost 1.32-fold among subjects with three/four elevated liver enzymes. Conclusion: The higher incidence of elevated liver enzymes was associated with an increased likelihood of MetS. Including liver markers in diagnosing and predicting MetS holds promise and is considered a possible approach.
RESUMO
Although hematuria is not life-threatening, some could be the result of a more severe condition. Our objectives are to report on the prevalence and risk factors of asymptomatic microscopic hematuria (AMH) in the prospective epidemiological research studies of the Iranian adults (PERSIAN) Guilan cohort study (PGCS) population. This cross-sectional study was conducted from 2014 to 2017 and consisted of 10,520 individuals aged 35-70. Data collection was conducted using a questionnaire during a face-to-face interview. The urine analyses (UA) were done up to 2 h after sample collection. Based on a urine microscopy evaluation, AMH is defined as 3 or more red blood cells per high power field (HPF). Simple and multiple logistic regression analysis was conducted to explore factors associated with AMH. The prevalence of AMH in this study was 34.1% and was more prevalent in participants of older ages and female gender as well as those with low educational level, underweight-body mass index (BMI), high physical activity, smoking, alcohol consumption, and kidney stone disease. On the other hand, obesity, opium, and diabetes decreased the likelihood of AMH. The results of the present study shed light on the prevalence and risk factors of AMH and suggested that a significant portion of the study population is affected by AMH. Considering the lack of consensus on a definite clinical guideline for AMH in our country, the results of the present study could be used to design a unit algorithm for screening and therapy of AMH.

BACKGROUND: Ultrasound is an important method to determine the volume of the gallbladder and check its structure. Considering the variation in the size and volume of the gallbladder in disease and physiological conditions, determining the volume of the gallbladder is clinically valuable. This study was carried out to evaluate the gallbladder volume and its association with patients' demographic data in the Prospective Epidemiological Research Studies of Iranian Adults (PERSIAN) Guilan cohort study (PGCS) population. METHODS: In this cross-sectional study, 957 individuals aged 35-70 participated in determining the gallbladder volume by a radiologist based on the ultrasound method. The demographical data were collected using a questionnaire. After fasting for 12 h, the ultrasound was performed with an Ultrasonic device (Sonix SP series) with a 3.5 to 5 MHz probe. RESULTS: The total frequency of gallbladder lesions was 2.2%. The results showed a significant association between marriage and gender with the presence or absence of lesions in the studied participants (P < 0.05). Also, significant differences were reported between the volume of gallbladder and gender, body mass index (BMI), social and economic status (SES), metabolic equivalent of task (MET), history of cardiovascular disease (CVD), and hypertension (P < 0.05). The results of a linear regression represented a significant association between gender, BMI, MET, and CVD and the mean volume of the gallbladder (P < 0.05). However, there was no significant association between the presence or absence of a lesion and the individuals' average gallbladder volume (P > 0.05). CONCLUSION: According to our results, gender, BMI, MET, and CVD were significantly associated with gallbladder volume.

Introduction: Tinnitus can be associated with many auditory and non-auditory factors, and its prevalence varies widely in the literature. There is no large sample of published data on tinnitus prevalence and its associated factors in Iran. Here, we analyzed the PERSIAN Guilan Cohort Study (PGCS) data and reported the prevalence of tinnitus and some of the risk factors related to tinnitus in the Iranian population. Materials and Methods: This cross-sectional study was conducted on 10520 men and women between 35 and 70 years old. The prevalence of tinnitus and associations between tinnitus and age, sex, habitat, marital status, employment status, socioeconomic status, educational level, lifestyle habits, and comorbid diseases were examined using simple and multiple logistic regression analyses. Results: The prevalence of tinnitus was 6.4% in this study. Based on the adjusted analysis, only older age (odds ratio: 2.60, 95% confidence interval: 1.88 - 3.60), residency in a rural area (odds ratio: 1.22, 95% confidence interval: 1.03 - 1.44), cigarette smoking (odds ratio:1.33, 95% confidence interval: 1.04 - 1.72), and having other comorbidities (odds ratio: 2.75, 95% confidence interval: 2.19 - 3.44) were related to tinnitus. In addition, the results of subgroup analyses by sex were mostly consistent with the overall analysis. Conclusions: Our results revealed that the prevalence of tinnitus in the north of Iran is comparable with other communities. Age and other comorbidities were among the most related factors to tinnitus.
RESUMO
BACKGROUND: Diabetes mellitus (DM) is known as one of the most prevalent non communicable diseases with high cost of health services in the world. Present study was conducted to assess the frequency of high risk people for diabetes mellitus based on American Diabetes Association (ADA) risk score among Iranian people. METHODS: Present study was a cross sectional study on non-diabetic subjects aged 35-70 years from 10,520 PERSIAN Guilan Cohort Study (PGCS). ADA risk score was calculated for every individual through an online calculator. Receiver operating characteristic (ROC) curves was used to assess diagnostic accuracy of the anthropometric indices to identify individuals with high risk ADA score for developing DM, represented by the area under the curve (AUC). RESULTS: From 7989 study subjects, ADA risk score found 3874 (48.5%) and 1912 (23%) at risk for developing PreDM and DM, respectively. The results of ROC curve analyses showed the highest diagnostic value was related to waist circumference (WC) in total population and Waist to Height Ratio in both sex (0.695 total, 0.743 female, 0.744 male). The cut-points of WC in total population to identifying high risk group were 97 cm. CONCLUSIONS: A considerable number of populations were classified as high ADA risk for developing DM and PreDM that provide the importance of prevention strategies. Present study showed WC and Waist to Height Ratio have the highest diagnostic value to identify high risk people for DM.

BACKGROUND: Vitamin D (VD) insufficiency has now become a global problem throughout the world. The association between increasing body mass index (BMI) and VD insufficiency has attracted great attention in recent researches. The aim was to study if BMI was independently associated with serum 25-hydroxy VD in a large population-based study, specify by gender. METHODS: Data on 9520 adults 35 years and older participating in PERSIAN Guilan Cohort Study (PGCS) were used. Serum levels of 25-hydroxy VD less than 20 ng/mL (50 nmol/L) was used as a measure of VD inadequacy. Multiple logistic and linear regression analyses were used to estimate the strength of the association between VD and BMI before and after adjusting for demographic factors and lifestyle variables. RESULTS: After adjustment in male population, overweight (adjusted OR = 1.2, P < 0.05) and obese (adjusted OR = 1.4, P > 0.05) individuals were more likely to have VD inadequacy than normal weight counterparts. Moreover, there was a weak inverse linear association between BMI and serum 25 (OH) D levels in males (ß = -0.14, P value > 0.05). In contrast, no significant associations between BMI and serum 25 (OH (D levels were observed in females. In male population, higher BMI were associated with lower serum vitamin 25 (OH) D levels. CONCLUSIONS: However, association between BMI and VD level was not observed in female population. The suggestion of current study for public health was special consideration to serum VD levels in over weight and obese males.
RESUMO
BACKGROUND: The combination of sofosbuvir and daclatasvir has shown preliminary efficacy for hospitalized patients with COVID-19 in four open-label studies with small sample sizes. This larger trial aimed to assess if the addition of sofosbuvir/daclatasvir to standard care improved clinical outcomes in hospitalized patients with COVID-19. METHODS: This was a placebo-controlled, double-blind, randomized clinical trial in adults hospitalized with COVID-19 at 19 hospitals in Iran. Patients were randomized to oral sofosbuvir/daclatasvir 400/60 mg once-daily or placebo in addition to standard of care. Patients were included if they had positive PCR or diagnostic chest CT, O2 saturation <95% and compatible symptoms. The primary outcome was hospital discharge within 10 days of randomization. Secondary outcomes included mortality and time to clinical events. The trial is registered on the Iran Registry of Clinical Trials under IRCT20200624047908N1. RESULTS: Between July and October 2020, 1083 patients were randomized to either the sofosbuvir/daclatasvir arm (n = 541) or the placebo arm (n = 542). No significant difference was observed in the primary outcome of hospital discharge within 10 days, which was achieved by 415/541 (77%) in the sofosbuvir/daclatasvir arm and 411/542 (76%) in the placebo arm [risk ratio (RR) 1.01, 95% CI 0.95-1.08, P = 0.734]. In-hospital mortality was 60/541 (11%) in the sofosbuvir/daclatasvir arm versus 55/542 (10%) in the placebo arm (RR 1.09, 95% CI 0.77-1.54, P = 0.615). No differences were observed in time to hospital discharge or time to in-hospital mortality. CONCLUSIONS: We observed no significant effect of sofosbuvir/daclatasvir versus placebo on hospital discharge or survival in hospitalized COVID-19 patients.

BACKGROUND: Dietary supplements (DSs) use have become a growing trend worldwide, and it may be affected by demographic and sociocultural factors. Some people use supplements with the thought that they can improve their health, reduce symptoms and prevent disease. The aim of the present study was to define the frequency of DS use and its association with socioeconomic factors among participants with selected main non-communicable chronic diseases (NCDs) (diabetes, cardiovascular disease (CVD), hypertension (HTN), cancers, and obesity in the north of Iran. METHODS: This large cross-sectional study was conducted as a part of the PERSIAN Guilan cohort study. Supplement use during last year and its type, demographic factors, socioeconomic status, lifestyle habits were asked by face-to-face interview. The history of chronic disease was defined by a trained team. Data were analyzed using SPSS. The chance of supplement use according to demographic, socioeconomic, and lifestyle variables and history of chronic disease was analyzed by logistic regression. RESULTS: 10,520 men and women aged 35-70 years in Some'e Sara County (including urban regions and 39 villages) were studied. About 25% of participants consumed DSs. The highest consumption of DS was calcium/vitamin D (11.1%), ferrous sulfate (8.8%), and vitamin D pearl or ampoule (7.7%). The highest percent of the history of chronic disease was central obesity (62.7%), HTN (43.2%), and general obesity (32.7), respectively. After adjustment for confounders, those with female gender, the highest age ranges (55-65 and > 65 years), high academic education, living in urban regions, and good economic status were more likely to be DSs consumers; however, married and smoker subjects were more likely to consume DS. Participants who had a history of diabetes, HTN, CVD, Obesity, and Central Obesity were more likely to intake DS in comparison with healthy subjects. CONCLUSION: This study showed that a quarter of the participants were DS users. Female sex, older age groups, and higher educated participants, and among chronic disease, patients with HTN, CVD, and diabetes were more likely to be users of any DS.
RESUMO
Food behavior and dietary pattern are major parameters affecting the health status of people. The objective of this study was investigation of food behaviors in people inhabited in North of Iran to find out association of the effective indices (related to salt and fried foods) with hypertension and other cardiovascular diseases (CVDs). This large cross-sectional study was conducted on 10,520 participants and their sociodemographic, medical, and food behavior information were evaluated. Association of salt intake with CVDs and stroke was studied by portfolio at risk (PAR) formula. Association of food behavior with hypertension and CVDs was surveyed by chi-square test. Differences were significant at P≤0.05. Analysis of medical information revealed that 43.18% and 8.18% of the participants had hypertension and CVDs, respectively; mostly in women. Significant association was observed between salt-related behaviors and hypertension in the participants. Regarding salt intake, higher PARs were calculated in women than men (2.26 vs. 1.88 for PARCVDs and 3.66 vs. 3.05 for PARstroke), and urban than rural inhabitants (4.56 vs. 3.66 for PARCVDs and 7.27 vs. 5.88 for PARstroke). No significant contribution was observed between oil-related behaviors and CVDs. The majority of participants were well-informed about appropriate preparation and consumption of fried foods but not a healthy behavior about salt intake. Considering the significant association of salt-related behaviors with hypertension, conducting educational programs by healthcare practitioners in the population is suggested.
RESUMO
BACKGROUND: The persistence of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) RNA in the body fluids of patients with the novel coronavirus disease 2019 (COVID-19) may increase the potential risk of viral transmission. There is still uncertainty on whether the recommended quarantine duration is sufficient to reduce the risk of transmission. This study aimed to investigate the persistence of SARS-CoV-2 RNA in the nasopharyngeal, blood, urine, and stool samples of patients with COVID-19. METHODS: In this hospital-based longitudinal study, 100 confirmed cases of COVID-19 were recruited between March 2020 and August 2020 in Guilan Province, north of Iran. Nasopharyngeal, blood, urine, and stool samples were obtained from each participant at the time of hospital admission, upon discharge, 1 week after discharge, and every 2 weeks until all samples were negative for SARS-CoV-2 RNA by reverse transcription-polymerase chain reaction (RT-PCR) assay. A survival analysis was also performed to identify the duration of viral persistence. RESULTS: The median duration of viral RNA persistence in the nasopharyngeal samples was 8 days from the first positive RT-PCR result upon admission (95% CI 6.91-9.09); the maximum duration of viral shedding was 25 days from admission. Positive blood, urine, and stool RT-PCR results were detected in 24%, 7%, and 6% of the patients, respectively. The median duration of viral persistence in the blood, urine, and stool samples was 7 days (95% CI 6.07-7.93), 6 days (95% CI 4.16-8.41), and 13 days (95% CI 6.96-19.4), respectively. Also, the maximum duration of viral persistence in the blood, urine, and stool samples was 17, 11, and 42 days from admission, respectively. CONCLUSION: According to the present results, immediately after the hospitalized patients were discharged, no evidence of viral genetic materials was found. Therefore, appropriate treatments were selected for the patients at this hospital. However, we recommend further investigations on a larger sample size in multi-center and prospective randomized controlled trials (RCTs) to evaluate the effects of different drugs on the shedding of the virus through body secretions.

INTRODUCTION: The prevalence of metabolic syndrome has increased in recent decades around the world and is currently reaching epidemic levels as it is a major public health and clinical concern. The aim of this study was to evaluate the prevalence of metabolic syndrome and its related demographic factors in a population-based study. METHODS: In this cross-sectional study, the target population consisted of 10520 individuals aged 35-70 years in Phase 1 of the Persian Guilan cohort study (Guilan site/Some'e Sara) that was conducted in 2014-2017. Demographic, anthropometric, blood pressure, and biochemical data were used in this study. The IDF definitions were used to diagnose the metabolic syndrome. RESULTS: The prevalence of the syndrome according to IDF and ATP definition was 42.87% (95% CI: 41.92-41.81) and 40.68% (95% CI: 39.74-41.62), respectively. The prevalence of components for central obesity, high triglyceride, HDL cholesterol, blood glucose, and hypertension components was 75.8%, 43.1%, 40.6%, 39.2% and 37.9%, respectively. All demographic variables were related to the syndrome, and among them age, gender, and residence were identified as independent and strong predictive variables in the regression model. More than 92% of the population had at least one component of the syndrome. CONCLUSION: The results of the study show a high prevalence of metabolic syndrome risk factors. It is essential to educate healthy lifestyle behaviors and further health education in the high-risk groups identified in this study, especially the elderly, women, and rural residents.
RESUMO
OBJECTIVE: This study was conducted to assess the prevalence of central and general obesity and compare nine anthropometric indices as predictors of the risk factors for cardiovascular disease (CVD) in Iranian adults. METHODS: A total of 10,520 adults between ages 35 and 70 years old who were referred to the PERSIAN Guilan Cohort Study were included in this study. Anthropometric indices, including body mass index (BMI), waist circumference (WC), waist to height ratio (WHtR), waist to hip ratio (WHR), conicity index, hip circumference (HC), waist to hip to height ratio (WHHR), body adiposity index, and a body shape index (ABSI), were measured using the standard methods. The risk factors for CVD (diabetes mellitus, hypertension, and out of range lipid profiles) were defined by laboratory tests and medical history. The odds ratio of the risk factors based on a unit increase in anthropometric indices was examined by an adjusted logistic model. RESULTS: The mean of all anthropometric indices was higher in women than in men (p<0.01). After adjusting for confounders, the risk of diabetes mellitus, hypertension, and hypertriglyceridemia increased with an increase in all anthropometric indices. The highest risk of diabetes mellitus and hypertriglyceridemia was found in higher WHHR. The highest risk of low high density lipoprotein cholesterol (HDL C) and high low density lipoprotein cholesterol (LDL C) was found in an increase in the WHR and ABSI, respectively. CONCLUSION: Our findings emphasize higher levels of general and central obesity in adults in the north of Iran. The WHHR and WHtR seem to be more valuable indices than BMI and WC for predicting distinct risk factors for CVD. However, the WHR was the strongest index for the prediction of high LDL C/HDL C ratio.

OBJECTIVE: Hepatitis B (HB) and C (HC) are two severe viral infectious diseases with a deleterious impact on global health. This study aimed to evaluate the prevalence of HB and HC in the Prospective Epidemiological Research Studies of the Iranian Adults (PERSIAN) Guilan Cohort Study using immunological and molecular methods. RESULTS: The blood samples were obtained from 10,520 enrolled participants. Complete biochemical and hematological tests, as well as urine analysis, were assessed. The presence of HBsAg, anti-HBs, anti-HBc, and anti-HCV antibodies for all participant and HBeAg and anti-HBe antibodies for HB-positive patients were evaluated. Moreover, HB genomic DNA and HC genomic RNA were extracted from serum samples of HB-positive patients. The real-time PCR assay was employed to quantify the gene copies of hepatitis B and C viruses. HC genotyping was also performed. The prevalence of HB and HC was 0.24% (95% CI 0.16-0.35) and 0.11% (95% CI 0.06-0.19), respectively. Rural participants were significantly more HB-positive than the urban people (P = 0.045), while males were significantly more HC-positive than the females (P = 0.013). The prevalence of HB and HC in this area were lower than those of other geographical locations of Iran, which may be due to different lifestyles or other unknown reasons.

Background: Estimates region-related prevalence of hypertension and attempts to identify its related factors at the district levels are required for prevention and management of hypertension. Objective: The aim of this study was to investigate the epidemic features and related factors of hypertension and its awareness, treatment, and control rates among the northern Iranian population. Methods: It was a community based cross-sectional study based on data from PERSIAN Guilan Cohort Study (PGCS). In total, 10,520 participants (aged 35-70 years) from the Guilan Province in northern Iran included in this study, between October 8, 2014, and January 20, 2017. Hypertension was defined as systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg or a prior diagnosis of hypertension or being on antihypertensive medication. Potential correlates of hypertension and its awareness, treatment and control were analyzed by multivariate logistic regression adjusted for demographic factors, anthropometric characteristics, lifestyle variables, past medical history, and laboratory data. Results: The prevalence of hypertension was 43.2% and the hypertension awareness, treatment, and control rate were 53.4%, 49.8%, and 73.7%, respectively. The multivariate logistic regression analyses revealed that older age, urbanization, lower education, overweight and obesity, lower physical activity, prediabetes and diabetes, cardiovascular disease, psychiatric disorder, positive family history of hypertension and raised serum creatinine were independently associated with presence of hypertension. Awareness of hypertension was greater in the female sex, older age, rural residency, higher education and patient with comorbidities. Older age, rural residency and comorbidities were associated with treatment of hypertension. Control of hypertension was better among younger age, higher education, normal weight and higher physical activity. Conclusion: Hypertension is highly prevalent in the northern Iranian population. About half of affected persons are unaware of their disease and untreated. Modifying risk factors (such as weight lose and increase physical activity) and increasing hypertension awareness (by screening) is essential for primary and secondary prevention of high blood pressure in this population, especially in urban areas and among males, younger ages, and less educated.

BACKGROUND: One of the important issues related to metabolic syndrome is the underlying factor that remains controversial. The purpose of this study was estimating exploratory factor analysis (EFA) to reveal underlying factors that may explain the observed variants of metabolic syndrome (MetS) components in a population-based study. METHODS: In this cross-sectional study, the target population consisted of 10,520 individuals aged 35-70 years from Phase 1 of the PERSIAN Guilan cohort study conducted between 2014 and 2017. Exploratory factor analysis (EFA) of components of the metabolic syndrome, including waist circumference (WC), systolic (SBP) and diastolic (DBP) blood pressure, triglyceride (TG), high-density lipoprotein (HDL) and fasting blood glucose (f-Glc) was performed across the population as well as by gender. RESULTS: EFA results in the whole population based on eigen values > 1 showed two factors that explain 55.46% of the total variance. Taking factor loadings above 0.3, the first factor included systolic blood pressure, diastolic blood pressure, and waist circumference - called the blood pressure factor. Also, the second factor included triglycerides, negative-loaded HDL, and fasting blood glucose, which was named as lipid factor. In terms of gender, the first factor was similar to the whole population pattern, but in the second factor, in addition to the two components of blood lipids, waist size for men and in fasting blood glucose for women was launched. CONCLUSION: Hypertension and lipids were substantial factors, and obesity is an important factor in this study. Hypertension, having the highest factor load, can generally be a valuable screening parameter for cardiovascular and metabolic risk assessment.

BACKGROUND: Blood pressure (BP) measurement accuracy is critical to the diagnosis and management of hypertension. The aim of the present study was to validate the Omron HBP-1100-E professional blood pressure measuring device in accordance with the American Association for the Advancement of Medical Instrumentation in Iranian adults. MATERIALS AND METHODS: Simultaneous blood pressure auscultator measurements were obtained by two observers using mercury sphygmomanometers as a reference, sequentially with a measurement by using the Omron HBP-1100-E device. Absolute device-reference blood pressure differences were categorized into three error categories (within 5, 10, and 15 mmHg), and mean device-reference blood pressure difference (standard deviation) was calculated and evaluated using the American Association for the Advancement of Medical Instrumentation criteria. RESULTS: A total of 85 participants (250 paired readings) were enrolled to the study. 26.8%, 55.6%, and 79.6% of the device-reference blood pressure differences agreed to within 5, 10 and 15 mmHg, respectively, for systolic blood pressure, and 39.6%, 69.2%, and 81.6% of measurements for diastolic blood pressure, respectively, and failed to pass the protocol criteria. The mean device-reference blood pressure difference was 8.0 ± 13.1 mmHg for systolic BP and 2.2 ± 11.3 mmHg for diastolic BP, and was >5.0 ± 8.0 mmHg (required criteria). CONCLUSION: Omron HBP-1100-E professional blood pressure monitor is not desirable for measuring the BP for Iranian adults as it overestimates blood pressure in this population.
RESUMO
BACKGROUNDS/AIMS: Acute pancreatitis is the most widespread complication of endoscopic retrograde cholangiopancreatography. Here, we investigated the efficacy of rectal suppository naproxen, sublingual isosorbide dinitrate and their co-administration in the prevention of post-ERCP pancreatitis. METHODS: This double-blind randomized clinical trial carried out from June 2015 to February 2016 at the Gastrointestinal and Liver Diseases Research Center in Rasht, Iran. A total of 585 patients were selected from candidates for diagnostic or therapeutic ERCP by using the simple sampling method. Patients divided into three groups. Group A received 500 mg naproxen, group B took 5 mg isosorbide dinitrate, and group C was co-administrated both agents before ERCP. The primary outcome measure was the development of pancreatitis onset of pain in the upper abdomen and increase of serum amylase activity more than 3 times over the upper normal limit (60-100 IU/L) within first the 24 h post-ERCP. RESULTS: Totally, 80 patients developed PEP included 29 (4.9%), 24 (4.1%), and 27 (4.6%) patients in groups A, B, and C, respectively (p=0.845). Longer ERCP time (p=0.041), using diazepam (p=0.033), a higher number of pancreatic ducts cannulation (pï¼0.001), pancreatic duct injection (p=0.013), and using pancreatic stent (p=0.004) were the predisposing factors for PEP. CONCLUSIONS: Our findings indicated that prophylactic naproxen suppository or isosorbide dinitrate sublingually or co-administration had no significant difference in the prevention and severity of PEP, however, enhancing the endoscopist's skills can be effective. Departments and educational hospitals should develop their assessment and quality assurance measures for the training of fellows' not only technical training but also an understanding of the diagnostic and therapeutic roles of the procedure.
RESUMO
BACKGROUND: One of the public health concerns is Vitamin D deficiency. The aim of this study was to determine the prevalence of vitamin D inadequacy and to determine its reproductive factor correlates in northern Iranian women. METHODS: This study, conducted on 5096 females aged 35-70 years. The study was based on data from PERSIAN Guilan Cohort Study (PGCS), a prospective, population-based cohort study in Guilan, Iran. History of reproductive and gynecologic factors, including age at menarche, age at first marriage, number of pregnancies or live births, age at first pregnancy, duration of breastfeeding, number of abortions, age and type of menopause status, use of oral contraceptives or hormone replacement therapy, history of hysterectomy, tubectomy or oophorectomy and history of gestational diabetes and hypertension was collected. Serum 25(OH) vitamin D was measured. RESULTS: The mean 25(OH)-D concentration was 21.78 ng/mL, and 53.5% of women had vitamin D inadequacy. The multivariate analyses revealed that younger age (36-45 years) [>66 years adjusted odds ratio (aOR) = 2.1, 95% CI 1.7-2.7, 56-65 years aOR = 1.7, 95% CI 1.3-2.1 and 46-55 years aOR = 1.4, 95% CI 1.1-1.7], not consuming oral contraceptives [aOR = 1.1, 95% CI 1.05-1.3] and pre-menopausal status [aOR = 1.4, 95% CI 1.2-1.6] were significantly independently associated with vitamin D inadequacy. CONCLUSION: Vitamin D inadequacy is common in northern Iranian women. The reproductive factors that independently correlated with vitamin D statues are oral contraceptive consumption and menopausal statue.
