Introduction: Self-care activities have been used as a framework for patient-centered diabetes education. Accumulating evidence suggests that patients who take a more active role in their care process achieve better health outcomes. The present study aimed to design a systematic review of scientific resources over the past decade to identify variables that determine self-care behaviors in patients with type II diabetes (T2D). Materials and Methods: MeSH keywords were applied to search several databases including PubMed, EMBASE, CINAHL, Scopus, Med line, DOAJ, Oxford, and the Scientific Information Database for English and Persian language studies between August 2010 and 2019. The process of conducting and reporting this systematic review was guided according to the statements of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Results: The literature search yielded 1,813 publications, of which 62 were included in this study after eliminating non-relevant and overlapping papers. A total of 18 factors and variables determining selfcare behaviors were obtained in patients with T2D. The most influential variables were self-efficacy, knowledge, level of education, age, duration of diabetes, and health literacy. Conclusion: In sum, six main factors were identified as determinants of self-care behaviors in patients with T2D which self-efficacy was the strongest predictor of self-care and is expected to be considered in designing and implementing educational programs and behavior change in diabetic patients. Further studies in the future may support the findings of this review study. [ABSTRACT FROM AUTHOR]

Introduction: Gastrointestinal bleeding (GIB) is one of the most important diseases in internal medicine, which can occur due to bleeding in any of the gastrointestinal organs. The best diagnostic method for identifying the source of bleeding in patients is endoscopy and colonoscopy. Therefore, this study was conducted to determine the causes and the most common risk factors for GIB in patients referring to Shahid Mustafa Khomeini Hospital in Ilam. Material & Methods: In this retrospective analytical study, all patients with clear gastrointestinal bleeding symptoms, including melena, hematemesis, hematochezia, and passing clots, who referred to Shahid Mustafa Khomeini Hospital in Ilam from 2014 to 2019, were evaluated. The demographic information of the patients, their medical history, and the description of the medications they were taking, which were recorded in their medical records, were entered into the questionnaire form. Data analysis was performed using descriptive and inferential statistical methods. Findings: In this study, 650 patients with an average age of 57.24 years, ranging from 19 to 99 years, were included. The majority of patients were in the older age group (above 60 years) and were male. The most common complaint among patients was hematemesis (41.4%), while anemia was the least common complaint (1.8%). The most common causes of gastrointestinal bleeding in both genders were peptic ulcer, gastric mass, and esophageal varices. There was a significant correlation between age and gastrointestinal bleeding symptoms (p < 0.05). Gastrointestinal bleeding symptoms, including hematemesis, melena, and rectorrhagia, were more common in men and in smokers. Alcohol consumption also had an impact on the occurrence of gastrointestinal bleeding with hematemesis, melena, and rectorrhagia. Discussion & Conclusion: Endoscopy and colonoscopy are the best diagnostic methods for patients with gastrointestinal bleeding. Therefore, this study was conducted to determine the causes and the most common risk factors for GIB in patients referring to Shahid Mustafa Khomeini Hospital in Ilam from 2014 to 2019. The findings of this study can help improve the diagnosis and management of gastrointestinal bleeding in these patients. [ABSTRACT FROM AUTHOR]

Background Oral lesions can affect people’s quality of life by interfering with chewing, swallowing, and speech. These lesions may originate from epithelial or mesenchymal tissues. Malignant oral lesions can be life-threatening. Epidemiological data of oral lesions in Iran is limited. Objective This study aims to investigate the frequency of oral lesions in Rasht, Iran. Methods In this cross-sectional study, histopathologic data of oral lesions reported by Razi laboratory in Rasht from 2015 to 2019 were evaluated. The data collected: Patients’ age and sex, histopathologic findings, and location, type and origin of lesions. Non-specific diagnoses and dental and bone lesions were excluded. Results A total of 259 pathologic reports were included. The mean age patients was 52.09±19 years, and 40.2% were male. Oral lesions in patients aged <40 years were mainly benign (64.2%), whereas half of lesions in patients ≥70 years were mostly malignant. Tongue was the most common location of the lesions (34.7%) and the main location for malignant lesions (46.7%). Benign lesions were significantly higher in females whereas malignant lesions were significantly higher in males (P=0.011). Epithelial tissues were the most common site of origin (49%) and salivary glands were the least common site of origin (11.6%) for oral lesions. Conclusion Malignant oral lesions are more common in Iranian men aged >70 years, where the tongue is the most common site of involvement and epithelial tissue is the main site of origin.

Background Dental abnormalities are considered important, since they cause aesthetic and functional problems for people. Orthodontic treatment becomes more complicated when craniofacial abnormalities are accompanied with dental abnormalities. Objective This study aims to compare the frequency and type of dental abnormalities among patients with different skeletal malocclusion classes in northern Iran in terms of age and gender. Methods Participants were 310 patients (32.9% Class I, 33.9% Class II, and 33.2% Class III). They were evaluated with respect to hypodontia, hyperdontia, impaction, microdontia, macrodontia, and dens invaginatus/evaginatus. Association of the prevalence of dental abnormalities with the type of malocclusion and gender was assessed by chi-square test and Fisher’s exact test, while independent t-test was used to determine its association with age. Results The overall frequency of dental abnormalities was 33%. Class III patients had the highest rate of dental abnormalities (40.8%); however, the difference was not statistically significant (P=0.105). Hypodontia and impacted teeth were the most frequent abnormalities in all malocclusion groups. Occurrence of tooth impaction differed significantly among the three malocclusion groups (P<0.001), where the highest rate belonged to the class III group. Hypodontia was more frequent in males (P=0.040). Tooth impaction and microdontia were the two abnormalities that showed significant association with age (P<0.05). Conclusion Dental abnormalities in northern Iran is more prevalent among people with the skeletal class III malocclusion. The prevalence of some dental abnormalities is associated with gender and age. [ABSTRACT FROM AUTHOR]

Background and Aim: Women are the central pillar of social development and the main axis of family health. Success, survival, and promotion of society depend on the health of women in society. Since Health Promotion lifestyle and psychological well-being are important determinants of health, this study was conducted to determine the Health Promotion lifestyle and psychological well-being in women attending the health centers of Arak City in 2019. Methods & Materials: In this cross-sectional study, among women who attended health centers in Arak City, 221 women who met the inclusion criteria were included in the study by continuous sampling and the form of demographic information, health promoting lifestyle profile-Ii (HPLP-II), and Ryff Psychological well-being Questionnaire was completed. Data were described using descriptive statistics of frequency, frequency percentage, mean, standard deviation, and data analysis by analysis of variance, independent t-test, and regression using SPSS software v. 19.

Background Exercise and physical activity improve damage and destructive changes in the peripheral nervous system. Objective This study aims to investigate the effects of resistance aerobic training on the expression of SEMA3A and NCAM genes and proteins of soleus muscle in male rats of different age groups. Methods A total of 30 male Wistar rats in three groups of 2-week-old (infant) (n=10), 6-week-old (young) (n=10), and 96-week-old (elderly) (n=10) were divided into two groups of training and control. The training program included 6 days of resistance and aerobic training one day in between. The rats were euthanized and the soleus muscle was extracted 48 h after the last training session. A fluorescent microscope was used to measure SEMA3A and NCAM proteins in muscle fibers. Gene expressions were measured by real-time polymerase chain reaction. Results The results showed that SEMA3A gene expression was not significantly different between exercise and control groups in all three age groups; however, SEMA3A protein expression was significantly reduced in infant and young exercise groups (P≤0.001). Also, NCAM gene expression was not significantly different between training and control groups in all three age groups; while there was a significant decrease in NCAM protein expression in young and old training groups compared to the control group (P≤0.001). Conclusion The results showed that resistance aerobic training can inhibit the process of peripheral nerve damage in infant and young rats, as well as the growth and strength of the neuromuscular junction in young and elderly rats.

Background and Objectives Change in the age structure of the population affects many activities and processes, and most countries are expected to enter the old population phase by 2050. Today, for various reasons, the consumption of blood and blood products has increased. The aim of this study was to investigate the age change in donor population during the years 1390 to 1397 and compare it with the society's age change algorithm to determine if the latter affects the former. Materials and Methods In this cross-sectional descriptive study, demographic information of 329631 blood donors from 1390 to 1397 from Blood Transfusion Software (Negareh software version 5/9) was extracted and the latest demographic information of the province was achieved using the website of the Statistics Center of Iran. Results Of the population of Yazd and Ardakan cities, 64.7% and 65.38% are within the appropriate age range for blood donation. The donor population of 18-30 years decreased by 30.7% in 2016 and 32.3% in 2018 compared with the year 2011 while other age groups almost increased. Mean age of donors in 2014 and 2017 were 44.2 and 40.05 years, respectively. Conclusions Due to the aging population, and the reduction of the population under the age of 30, it is necessary to take effective programs to maintain and attract 18-30 year old population for blood donation.

Background and Objectives HBV, a classic viral Transfusion Transmitted Infection(TTI), is considered an important health and blood safety issue in every society. Prevalence of HBsAg positivity is variable among Iranian blood donors nationwide. This study was performed to determine the frequency of HBsAg positive blood donors and the probable associated risk factors in Mazandaran province in 2013. Materials and Methods In this cross sectional descriptive study, demographic and donation data were gathered from IBTO data base (NEGARE). HBsAg positive donors were recalled for post test counseling and assessment of probable risk factors. SPSS 16 Chicago, χ2 and T-test were used as tools for data analysis. Results Among 131950 whole blood donors with mean age of 31.1 ± 9.5, 174(0.13%) proved to be HbsAg positive. Deferral rate was 16.6%. The highest and lowest positivity rates were observed at Babol and Galoogah, respectively. 95% of positive cases were detected among first time and male donors (p = 0.0001). Older age, lower education level, and first time donation were obtained as demographic risk factors primarily. No significant association between gender and marital status was found. However, post test counseling revealed nonimmune dental procedures, high risk sexual contacts, cupping, family history of Hepatitis, hospital admission, tattooing, history of surgery, Intravenous Drug Use (IDU), endoscopic procedures, transfusion history and needle stick as risk factors in HBsAg positive donors. Conclusions HbsAg positivity rate in Mazandaran province donors is compatible with the country rate (0.13%). Main risk factors except gender and marital status are almost similar to other studies.

Background: Acute upper gastrointestinal bleeding (UGIB) is a common and life-threatening problem. The identification of high-risk patients with regard to the need for urgent endoscopy and immediate intervention in patients with acute UGIB is a challenge for emergency physicians. The use of Rockall and Blatchford scoring systems has diminished this challenge to some extent. Therefore, the aim of this study was to investigate the role of Blatchford and Rockall systems in the outcomes of patients with UGIB referred to Emergency Department of Shahid Beheshti Hospital in Qom. Materials and Methods: In this retrospective analytic study, using a checklist of Blatchford and Rockall Scoring Systems and an easy sampling method, the clinical records of 194 patients with UGIB who aged over 18 years and had no trauma referring from 2013 to 2016 to the Emergency Department of Shahid Beheshti Hospital were studied. The role of Blatchford and Rockall Scoring Systems was investigated by Statistical tests regard to the significance level of p = 0.05. Results: This study showed a significant relationship between the interventions for patients with UGIB in Shahid Beheshti Hospital with predicted interventions by the Blatchford Scoring System (p = 0.000, kappa = 0.294). Also, there was a significant relationship between the place of admission of patients in Shahid Beheshti Hospital with predicted place of hospitalization determined by Rockall (p = 0.000, kappa = 0.182). Also, there was a significant relationship between age and Rockall Scoring System (p < 0.00001). Conclusion: The Blatchford Scoring System can be used as a clinical guide to determine the type of treatment intervention immediately and in the emergency department as a clinical guide to determine the type of patient's care.

Background: Helicobacter pylori (H. pylori) is the cause of most cases of peptic ulcers and gastric cancers and cause some of the most important cause of stomach cancer and lymphoma. The objective of this study was to evaluate the time trend of Helicobacter pylori prevalence and presence of intestinal Metaplasia over the period of 7 years in gastritis Iranian patients. Materials and Methods: In this cross-section study data related to H. pylori and intestinal Metaplasia (IM) among 14,860 consecutive gastritis patients, who referred to the gastrointestinal department of Tehran's Taleghani Hospital in Iran, was examined across the sex and age group. Results: The overall prevalence rate among patient with H. pylori infection was 83.5% (12406/14860) and 11,394 (84.1%) of them were related to the gastritis. The prevalence rate of H. pylori among patient with gastritis significantly higher (p<0.05) compared to patients without gastritis. In addition, the prevalence decreased with age while the presence of intestinal metaplasia increased with age (p<0.05). Conclusion: The results of this study showed that the prevalence of H. pylori infection in Iranian population has declined in recent years; nevertheless it seems to be highly prevalent in Iran. We also find a significant positive relationship between H. pylori infection and IM with gastritis. There is no association between sex and infection but in contrast with the most studies its prevalence decreased with age. [ABSTRACT FROM AUTHOR]

Background and Aim: Auditory lateralization is a binaural phenomenon that is the result of processing of interaural time and intensity cues in the central auditory system. The main advantage of this phenomenon in human is understanding speech in noisy environments due to the auditory sciene analysis and cocktail party effects. The aim of the present study was to assess the auditory lateralization ability in normal children. Methods: Participants were 80 normal school age children (8-11 years) of both genders, 42 girls and 38 boys. Lateralization functions were determined by interaural time difference (ITD) ranging from - 880 to +880 μs and interaural intensity difference (IID) ranging from -10 to +10 dB for high-pass and low-pass noise. Results: Interaural intensity difference lateralization functions were linear, while the interaural time difference lateralization functions were S-shaped with a clear linear component from -220 to +220 μs and with an asymptote from -440 to -880 μs and +440 to +880 μs. Generally, interaural intensity difference errors were significantly less than interaural time difference tasks (p<0.0001). Age effect was only present in interaural time difference tasks (p=0.001). Conclusion: According to these results, children with the age of 11 years performed better in lateralization using interaural time difference cues compared to other children; whereas there was no difference in performance in all ages when using interaural intensity difference cues.
