Abstract
There are inconclusive results available on the association between dietary fatty acid intake and the risk of hypertension (HTN) incident. In this study, we investigate the relationship between baseline dietary fatty acids intake including polyunsaturated fatty acid (PUFA), trans fatty acids (TFA), monounsaturated fatty acid (MUFA), and saturated fatty acid (SFA), and the risk of first incidence hypertension. The current prospective cohort study was carried out from the Ravansar Non-Communicable Diseases (RaNCD) cohort. A food frequency questionnaire (FFQ) with 118 items was used for the assessment of dietary data. Cox proportional hazards analyses were done to estimate hazard ratios (HR) and 95% confidence intervals (CIs) of the highest versus lowest quartile intake of SFA, PUFA, MUFA, and SFA and risk of HTN. Out of 7359 eligible participants, 597 new cases of HTN were identified over an average of 6.4 ± 1.33 years of follow-up. No significant relationship was observed between the fourth compared to the first categories of dietary SFA (HR: 0.82, 95% CI 0.55, 1.21; P trend: 0.476), MUFA (HR: 0.71, 95% CI 0.48, 1.06; P trend: 0.252), PUFA (HR: 0.86, 95% CI 0.62, 1.19; P trend: 0.315) and TFA (HR: 0.99, 95% CI 0.76, 1.27; P trend: 0.675), and risk of HTN. However, a significant inverse association between each 1 g per day increase in dietary MUFA intake during 6.4 years of follow up and HTN incident (HR: 0.97; 95% CI 0.94, 0.99; P 0.044) was observed. In brief, our study revealed that higher dietary MUFA intake was protectively associated with HTN incident. Dietary MUFA-rich foods should be encouraged to improve blood pressure.

Abstract
BACKGROUND In recent decades, more and more attention has been paid to the influence of nutrition on reproductive health. Nevertheless, the imminent association between diet-related inflammation and the risk of infertility has not yet been established. The aim of the current study was to investigate the ability of the Dietary Inflammatory Index (DII) to estimate infertility incidence in women. METHODS This cross-sectional study was conducted using data from Ravansar non-communicable diseases (RaNCD) cohort study on 4437 participants. The DII was calculated based on the reported consumption of up to 31 food parameters measured via a validated and reproducible 118-item food-frequency questionnaire (FFQ). Multiple logistic regression analysis was applied to estimate the multivariable odds ratio (OR) adjusted for potential confounding variables. RESULTS Out of all participants, 411 women (9.26%) were infertile. The mean ± SD age and weight of infertile women were 43.67 ± 7.47 years and 72.86 ± 13.02 kg, respectively. Statistical analyses showed the odds ratio of infertility in the fourth quartile (pro-inflammatory diet) was 1.76 times higher than in the first quartile (anti-inflammatory diet) of DII (95% CI: 1.57-2.02). CONCLUSIONS The findings of this study provide compelling evidence about the association between infertility and the quality of diet in women. Therefore, interventions and programs aimed at promoting a healthy lifestyle and using healthy diets can be considered as one of the effective approaches in the prevention and treatment of infertility in women.

Abstract
BACKGROUND Insulin resistance (IR) and obesity are risk factors for hypertension; triglyceride-glucose (TyG) is known as a surrogate for IR. The present study investigated the association between the triglyceride-glucose body mass index (TyG-BMI) index and the risk of hypertension in Iranian adults. METHODS This study was conducted on a sample of 8,610 participants from the baseline phase of the Ravansar non- communicable diseases (RaNCD) in Iran. A logistic regression model was used to evaluate the relationship between TyG-BMI and hypertension. Receiver operating characteristic (ROC) curve analysis was conducted to estimate the predictive power of TyG-BMI for hypertension. RESULTS A total of 4176 men and 4434 women with an average age of 46.74 years were examined. The anthropometric indices were significantly higher in hypertensive than normotensive subjects (P < 0.001). The level of physical activity was significantly higher in the bottom quartiles (P < 0.001). The odds of hypertension in the highest quartile and 3.10 (95% CI: 2.28, 4.16) times significantly higher than the bottom quartile of the TyG-BMI index. The discriminating ability of TyG-BMI to predict blood pressure was 61% (AUC: 0.61; 95% CI: 0.57, 0.63), and higher than BMI and TyG. CONCLUSION The TyG-BMI index is associated with an increase in the odds of hypertension. Therefore, the TyG-BMI index can be a new clinical index for early diagnosis of hypertension. Lifestyle modifications such as weight control through physical activity and a healthy diet can help improve IR and prevent hypertension.

Abstract
BACKGROUND Diabetes is one of the most common metabolic diseases in humans that cause disruption in glucose and fat metabolism. The determination of the ABO blood group system is hereditary and both diabetes and blood groups have a genetic basis. OBJECTIVES The aim of this study was to investigate the odds of type 2 diabetes for some blood groups. METHODS This case-control study was conducted in hospitals of Kermanshah in 2018. The case group consisted of patients with diabetes admitted to hospital and the control group of nondiabetic patients hospitalized in the surgical ward. Information such as age, sex, BMI, family history of diabetes and blood group is collected and analyzed by the univariate and multivariate logistic regression method. RESULTS A total of 750 patients were enrolled in this study. The number of participants in both groups was 375. The average ages of the participants were 50.51 and 51.62 years, respectively. 67.5% of the patients in the case group were female in comparison with 73.6% of those in the control group. The value of Rh+ in the case and control groups was 94.4 and 93.6%, respectively (p = 0.645). The chance of having diabetes for patients with blood group A was 76% higher than for those with blood group O (p = 0.006). CONCLUSION According to the results of this study, the odds of type 2 diabetes for people in blood group A was higher than for those in other blood groups. It is recommended that blood group A be considered as a risk factor in the screening of type 2 diabetes.

Abstract
Background:
Algal polysaccharide and oligosaccharide derivatives have been shown to possess a
variety of therapeutic potentials and drug delivery applications. Algal polysaccharides contain sulfated sugar
monomers derived from seaweed including brown, red, and green microalgae. Here, in this review, the recent
progress of algal polysaccharides’ therapeutic applications as anticancer agents, as well as underlying cellular and
molecular mechanisms was investigated. Moreover, recent progress in the structural chemistry of important polysaccharides
with anticancer activities were illustrated.
Methods:
Electronic databases including “Scopus”, “PubMed”, and “Cochrane library” were searched using the
keywords “cancer”, or “tumor”, or “malignancy” in title/abstract, along with “algae”, or “algal” in the whole text
until July 2018. Only English language papers were included.
Results:
The most common polysaccharides involved in cancer management were sulfated polysaccharides, Fucoidans,
Carageenans, and Ulvan from different species of algae that have been recognized in vitro and in vivo.
The underlying anticancer mechanisms of algal polysaccharides included induction of apoptosis, cell cycle arrest,
modulation of transduction signaling pathways, suppression of migration and angiogenesis, as well as activation
of immune responses and antioxidant system. VEGF/VEGFR2, TGFR/Smad/Snail, TLR4/ROS/ER, CXCL12/
CXCR4, TGFR/Smad7/Smurf2, PI3K/AKT/mTOR, PBK/TOPK, and β-catenin/Wnt are among the main cellular
signaling pathways which have a key role in the preventive and therapeutic effects of algal polysaccharides
against oncogenesis.
Conclusion:
Algal polysaccharides play a crucial role in the management of cancer and may be considered the
next frontier in pharmaceutical research. Further well-designed clinical trials are mandatory to evaluate the efficacy
and safety of algal polysaccharides in patients with cancer.

Abstract
OBJECTIVES Self-reporting can be used to determine the incidence and prevalence of hypertension (HTN). The present study was conducted to determine the validity of self-reported HTN and to identify factors affecting discordance between self-reported and objectively measured HTN in participants in the Ravansar Non-Communicable Diseases (RaNCD) cohort. METHODS The RaNCD cohort included permanent residents of Ravansar, Iran aged 35-65 years. Self-reported data were collected before clinical examinations were conducted by well-trained staff members. The gold standard for HTN was anti-hypertensive medication use and blood pressure measurements. The sensitivity, specificity, positive and negative predictive values, and overall accuracy of self-reporting were calculated. Univariate and multivariate logistic regression were used to examine the discordance between self-reported HTN and the gold standard. RESULTS Of the 10 065 participants in the RaNCD, 4755 (47.4%) were male. The prevalence of HTN was 16.8% based on self-reporting and 15.7% based on medical history and HTN measurements. Of the participants with HTN, 297 (18.8%) had no knowledge of their disease, and 313 (19.9%) had not properly controlled their HTN despite receiving treatment. The sensitivity, specificity, and kappa for self-reported HTN were 75.5%, 96.4%, and 73.4%, respectively. False positives became more likely with age, body mass index (BMI), low socioeconomic status, and female sex, whereas false negatives became more likely with age, BMI, high socioeconomic status, smoking, and urban residency. CONCLUSIONS The sensitivity and specificity of self-reported HTN were acceptable, suggesting that this method can be used for public health initiatives in the absence of countrywide HTN control and detection programs.

Abstract
OBJECTIVES Aluminum phosphide (ALP), also known in Iran as rice tablets, is one of the most effective rodenticides used to protect stored grain. However, ALP poisoning regularly causes mortality in humans. The aim of this study was to evaluate the characteristics and predictive factors of mortality from ALP poisoning. METHODS This study evaluated all patients with ALP poisoning referred to Imam Khomeini Hospital in Kermanshah Province, Iran from 2014 to 2015. For each patient, the following information was recorded: age, sex, the number of tablets consumed, the number of suicide attempts, the time elapsed from consumption to treatment, blood pressure, blood pH, HCO3 levels, and PCO2 . Differences between the survivors and non-survivors of ALP poisoning were analyzed using univariate logistic regression and multivariate analysis. RESULTS In this study, 48 patients were male and 29 patients were female (total: 77 patients). The average age of the survivors and non-survivors was 28.7 and 31.3 years, respectively. All cases (100%) of ALP poisoning were intentional, with the goal of committing suicide. The main predictive variables of mortality from ALP poisoning were blood pressure, blood pH, and time elapsed from consumption to treatment. CONCLUSIONS The likelihood of mortality in patients with ALP poisoning can be predicted using blood pressure, blood pH, and time elapsed from consumption to treatment. These findings may help healthcare providers take more effective measures to treat patients with ALP poisoning.

Abstract
BACKGROUND Helicobacter pylori cause chronic gastritis and subsequent diseases like gastric and duodenal ulcers and gastric adenocarcinoma. Current methods for detecting H. pylori have several disadvantages and it is of utmost importance to develop a simple, quick, accurate, and cost-effective diagnostic test. OBJECTIVES The aim of this study was to set up and evaluate a diagnostic value of loop- mediated isothermal amplification (LAMP) for detecting H. pylori. PATIENTS AND METHODS The analytical sensitivity values (limit of detection) of LAMP and polymerase chain reaction (PCR) were determined using serial dilutions of H. pylori DNA. Analytical specificity of the methods using new designed primers targeted ureC gene was also determined. RESULTS The detection limits of the LAMP and PCR assay were similar and were 10 fg of pure DNA of H. pylori, which is equal to 6 copy numbers of H. pylori genome. Analytical specificity of the tests was 100% because the tests were positive only with H. pylori DNA. CONCLUSIONS The analytical sensitivity of LAMP and PCR methods, using the designed primers, was 8 times more than any other reported methods. The designed methods are specific and sensitive for detection of H. pylori in different clinical and environmental samples.

Abstract
BACKGROUND The role of thalidomide in induction and long-term maintenance therapy in patients with multiple myeloma not eligible for stem cell transplantation remains unclear. The aim of the present study was to evaluate the effect of low-dose thalidomide as induction therapy and as maintenance therapy for 24 months in patients with a complete remission after the induction chemotherapy and to monitor the survival and relapse rates. METHODS Between October 2005 and September 2013, 50 patients with multiple myeloma received six courses of Cyclophosphamide-Vincristine Adriamycin and Dexamethazone (c-VAD) and pamidronate, and thalidomide 100 mg daily during induction, then thalidomide 100 mg daily for 24 months as maintenance. The effects of thalidomide were assessed objectively and subjectively. Whenever necessary, electromyography and nerve capacity volume were performed monthly for 6 months, then once every 3 months until the end of treatment. RESULTS Primary response was 96% (CR or very good PR in 48/50 patients). Fifteen out of the remaining 48 patients relapsed during the follow-up period. Nine out of the 15 patients who relapsed showed very good partial response to treatment and four patients showed partial response. Survival rate was 81% in these patients. The primary outcome measures showed a mean and median progression-free survival of 33 and 27 months, respectively, and a mean and median overall survival of 43 and 39 months, respectively. CONCLUSION Low-dose thalidomide during induction therapy combined with conventional chemotherapy and a 2-year maintenance may be effective in preventing the relapse and improving the overall survival.

Abstract
BACKGROUND Helicobacter pylori infection is etiologically associated with some important health problems such as gastric cancer. Because of the high clinical importance of H. pylori infection, development of a noninvasive test for the detection of H. pylori is desirable. METHODS In this study, a loop-mediated isothermal amplification (LAMP) targeted ureC of H. pylori was evaluated on 100 stool specimens and compared with a stool antigen test. Culture and rapid urease test were considered as gold standards. RESULTS The overall detection rate of the fecal antigen test and LAMP was 58% and 82%, respectively. The analytical sensitivity of the fecal antigen test and LAMP was 500 and 10 H. pylori cells/g and 10 fg DNA/reaction, which is equal to six H. pylori genome. CONCLUSION LAMP technique has been characterized by high sensitivity and low detection limit for the detection of H. pylori in stool specimen. Clinical diagnostic performance of LAMP was better than the stool antigen test.

Abstract
6556 Background: Arsenic trioxide has been used in the first line treatment of acute promyelocytic leukemia and also for recurrence after ATRA and chemotherapy. In this study, it we used it in induction of remission and maintenance therapy Methods: Between November 2005 to December 2011, 42 patients admitted in our department with APL diagnosis. There were 27 male and 15 women with a median age of 28 years. Arsenic trioxide started at 0.15 mg/kg intravenous infusion till patient’s bone marrows achieve to complete remission. Then, after 28 days rest, we did consolidation with Arsenic trioxide with the same dosage for 28 more days. We continued treatment with 14 days courses of Arsenic trioxide every 3-4 months for 2 years, as maintenance therapy Results: Four patients died during the first 20 days of treatment. Thirty-eight patients achieved to remission. Two patients refused to continue treatment after achieving to remission and excluded from this study. Thirty-six patients finished whole treatment. After a median follow-up of 54 months, 4 patients died due to disease relapse and one patient relapsed and initiated treatment with Arsenic and ATRA. Five patients faced leukocytosis over 100,000/ml. In these cases we were obligated to discontinue Arsenic for 3-4 days and did chemotherapy by Danourobicin for 2 days. Totally 8 patients died during remission induction and long-term follow up. One year, 3 and 5 years RFS were 97%, 87.1% and 79.4 respectively and we didn’t observe any relapse for patients who remained in remission after 5 years. Finally, 31 patients are alive and free of disease. The overall survival was 79.5% for our cohort. Conclusions: Arsenic trioxide is an effective treatment as the first line therapy for new cases of APL and long term therapy with will reduce the risk of diseases recurrence without any major toxicity in long time.

Abstract
Subcutaneous cervicofacial emphysema is a rare condition that results from various causes. Initially it might be misdiagnosed and managed as other clinical entities, such as angioedema. We report a case of self-induced subcutaneous facial emphysema in a prisoner who sought better living conditions by simulating an emergency.

Abstract
BACKGROUND/OBJECTIVE To evaluate the usefulness of abdominal sonography in the fasting state with no hypotonic agents in the detection and exclusion of gastric lesions. PATIENTS AND METHODS One-hundred patients with normal upper gastrointestinal endoscopy, 94 patients with a major gastric abnormality (including 59 intraluminal tumors, three submucosal masses, 29 ulcers, two polyps and one hypertrophied gastric mucosa) and 75 patients with minor gastric abnormalities (mainly gastritis) were enrolled into the study. RESULTS Of the 100 normal patients, ultrasound showed four false positive results with 96% specificity of the examination. Within the major gastric lesion group, ultrasound was true positive in 55 of 59 tumors, 15 of 29 ulcers, three of three submucosal masses and the case of giant gastric mucosa. It was negative in the detection of gastric polyps. It could detect only 8% of minor gastric abnormalities. CONCLUSION Abdominal sonography in the fasting state, if carefully performed, is sufficiently accurate in detection and exclusion of major gastric lesions. Therefore, although it cannot replace endoscopic and barium studies of the stomach, careful evaluation of the stomach is recommended in every sonographic evaluation of the abdominal cavity.
