The prevalence of VWD is different among various populations. The prevalence of this disorder in women with menorrhagia is less reported in Asia and Iran. The present study aimed to determine the prevalence of VWD in women of reproductive age with heavy menstrual bleeding (HMB). Materials and Methods: A total of 160 women in the reproductive age group (15-45 years) with HMB who referred to the hematology clinic of Kashan Shahid Beheshti hospital during 2019 participated in this cross-sectional study. Demographic characteristics, clinical testing, and physician-reported problems of each participate including age, menstrual cycle length, uterine myoma, and polyp were collected using a questionnaire, sonography, and physical examination of women by a physician. The laboratory tests included hemoglobin (Hb), ferritin, iron, and total iron-binding capacity (TIBC). Results: Fifteen patients (9.3%) with severe menstrual bleeding had VWD with a mean age of 34.60±6.85 years. The frequency of the uterine fibroid (myoma) in women with VWD was significantly higher than that in patients without VWD (p =0.03). The mean ferritin level among 15 women with VWD and 145 women without VWD was 23±4.28 ug/dL and 30.68±4.46 ug/dL, respectively (p =0.001). The mean serum iron in total participants was 35.3±11.48 ug/dL and VWD patients had a lower iron level compared to those without VWD (p =0.001). There was not a significant difference in TIBC level between women with and without VWD (p =0.6).

The present study was designed to determine the prevalence of self-medication and identify the factors associated with casual medication use among students of Larestan University of Medical Sciences in Iran in 2020. Methods: This is a cross-sectional descriptive-analytical study conducted in 2020. The study was conducted at Larestan University of Medical Sciences and 147 students entered the study through convenience sampling. The data collection tool was a researcher-made self-treatment questionnaire. After collecting the data, the SPSS software version 25.0 was used to analyze the data. Fisher’s exact test, independent t test, and chi-square test were used to investigate the relationship between the variables. A P value of less than 0.05 was considered statistically significant. Results: The prevalence of self-medication was 62.5%. The most common sources of self-medication were pharmacies and previous prescriptions. The most common illnesses treated with over-the-counter medications include colds, headaches, and digestive problems. The most important over-the-counter medications include painkillers, anti-colds, antibiotics, iron pills, calcium supplements, and antihistamines. A comparison of students’ attitudes towards medication showed that attitudes “I feel my problem has been treated with over-the-counter medications” and “I feel I have enough information about diseases and how to treat them” (the group who did have self-medication and the group who did not have self-medication) had a significant difference between the two groups (p <0.05). Conclusion: The results of the present study showed a high prevalence of self-medication among students. We recommend holding special training classes for the communities in order to provide information about the irreparable effects of self-medication and create new policies for prescribing and delivering medicine.","PeriodicalId":73448,"journal":{"name":"International journal of epidemiologic research","volume":"7 1","pages":"167-172"},"PeriodicalIF":0.0,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43870153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this regard, this study aimed to evaluate parasitic infections in cancer patients undergoing chemotherapy after referring to Kashani hospital of Shahrekord from January to May 2018. Methods: In this cross-sectional descriptive study, 750 stool samples were collected from 250 cancer patients undergoing chemotherapy (three fecal samples from each patient) and sent to the Parasitology Laboratory of Shahrekord University of Medical Sciences. All samples were examined macroscopically and microscopically through the direct method and a specific acid-fast staining method. To confirm the microscopic results, DNA was extracted from isolated parasites and amplification was performed by the polymerase chain reaction with the specific primers on positive samples. Results: In this study, 106 (42.4%) and 144 (57.6%) patients were males and females, respectively. In addition, 187 (74.8%) and 63 (25.2%) of them were living in urban and rural areas, respectively.

Regarding the issue of road traffic crashes, there are some contradictory findings about the efficacy of education, which may cause mistrust among professional circles and experts.Some scientists believe that most of the training programs do not necessarily cover all aspects of crashes and only address some of the concerns. Road traffic crashes are a multidimensional issue and can be influenced by various political, economic, social and cultural factors, and thus the efficacy of an education program can be reduced. The low efficiency of educational programs can have several reasons, which are mentioned below:1.Non-use of Specific Educational Theory The efficacy of some educational interventions poses a serious challenge for researchers. A simple search in scientific databases will result in various studies aiming to offer educational programs for different road users about the road traffic safety. These educational programs are sometimes designed and implemented without sufficient scientific evidence or without relying on specific educational theory. Some researchers believe that designing an educational intervention without considering the guiding theory in education is like prescribing a medication to a patient regardless of his/her physiology. The use of educational theories entails identifying the audience properly, presenting the educational content in an appropriate manner, and evaluating its feedback. It also helps audiences to gain a better understanding about the safety in relation to their own behavior as road users.2.Non-use of Various Methods for Providing the Educational Content Some educational interventions are based on learning context-dependent methods. However, learning context-dependent methods is not easily generalized among the target group. This type of educational delivery method is not adequately effective for some age groups, including children. Adopting various training methods tailored to the content and target groups such as role-playing, as well as using animation, cartoons, computer games, simulators, virtual reality technologies and augmented reality in training of traffic safety can increase the efficacy of such educational methods.3.Insufficient Attention to the Causation Network of Traffic Crashes Some believe that educational programs only emphasize on one topic, and generally fail to take into account the effect of other interventions. On the other hand, the designed educational intervention may focus on the wrong variable (as a factor influencing the occurrence of traffic crashes or the resulting injuries). For example, some drug abuse resistance education interventions focus on peer pressure as a variable with a direct causal effect, while the effect of the peer pressure in some studies is pale and other factors have a stronger causal effect. As for the road safety issue, some ","PeriodicalId":73448,"journal":{"name":"International journal of epidemiologic research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47228311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
