Introduction: Antibiotic arbitrary use by increasing resistance changed to a growing issue in the 21st century and its optimal use in hospital could be essential for reducing health system costs and drug side effects. Objectives: The aim of this study was to investigate the pattern of antibiotic use in prescribed prescription. Patients and Methods: This was a cross-sectional study that has been done on 300 prescriptions which selected randomly form Ardabil city hospitals. The anatomical therapeutic chemical classification system with defined daily doses (ATC/DDD) standard measurement method recommended by World Health Organization (WHO) was conducted in the study. The amount uses rate of each medication calculated by DDD/100 bed days. Data collected by a checklist and analyzed by statistical methods in SPSS version 21. Results: The highest prescribed antibiotic was ciprofloxacin with 32% and the total antibiotics uses rate during study period was 44/95 DDD/100 Bed days. The mean number of drugs and prescribed antibiotics in intensive care unit (ICU) ward was more than other wards. However, comparing the rate of antibiotics use between wards based on ATC/DDD method showed that the infection ward with 62.9 was more than other wards. The most form of used antibiotics with 69% was in the form of Ampule and in intravenously method with 64% in all wards. Conclusion: The results of this study showed that the most used antibiotics by considering the studied method, prescribed dose and the hospitalized days were in internal and surgery ward respectively but according ATC/DDD method the most used antibiotics was in infection ward.

Background & objectives: Designing knee osteoarthritis (KOA) prevention programs requires recognizing modifiable risk factors. This study aimed to determine the frequency of osteoarthritis in patients with knee pain referred to Imam Khomeini Hospital in Ardabil city. Methods: In this cross-sectional descriptive study, 850 patients with knee pain who were referred to the clinic of rheumatology in Imam Khomeini Hospital in Ardabil city were studied. Demographic and personal characteristics and medical history of OA were collected from the participants by a checklist. Osteoarthritis was diagnosed based on clinical and radiographic evidence by a rheumatologist. Results: Of all patients, 310 (36.5%) were diagnosed with knee osteoarthritis. The most of patients (33.5%) were in the age group of 50-59 years old, women (80.6%) and housewives (29%). 39.9% of all patiens had obesity and most of them (43.2%) have not exercised at any time. A family history of knee osteoarthritis was reported in 45.2% of patients, while a family history of joint replacement was reported in 6.1%. 15.8% of patients reported a history of previous knee trauma. The type of used toilet was traditional in 90.3%.

Background: Beta-thalassemia is one of the most common genetic diseases with autosomal recessive inherited patterns in the world and is one of the most common diseases in Iran that exists in all age and sex groups. Determining gene mutations in this disease can be effective in controlling and treating the disease. The present study determined the frequency of polymorphisms of Hinc, RSaI, RDB, and Xmn in patients with beta-thalassemia minor in Ardabil province. Methods: 53 beta-thalassemia patients referred to the genetic department of Imam Khomeini Hospital were studied. Blood samples were taken to determine the type of gene mutation. PCR samples were genetically evaluated to determine genetic mutations using RDB-Sequence-RFLP-Haplotype methods. Results: A total of 53 samples were examined, of which 56.6% were male and the rest were female. The most positive cases in the first and second ranks were related to XmnI and AvaII enzymes with 73.5% and 60.3%, respectively. The most common mutation extracted in the studied samples with 14 cases (26.4%) was IVS2.1. Among the most common mutations extracted by the RDB method was related to IVS 1.2 with 26.4%. Conclusions: The results of the present study showed that the distribution of genetic mutations in the studied samples can be different from other places. Also, by performing targeted genetic counseling, it is possible to control and prevent the disease in the future.

Glucose-6-phosphate dehydrogenase (G6PD) is one of the most common genetic deficiencies that affect approximately 400 million people worldwide. This study aimed to identify neonates with G6PD deficiency in Ardabil province during 2017-2018. This cross-sectional study was conducted on all term and preterm newborns in Ardabil Province from April 2018 to April 2019. The sampling method was census and in study duration, 1044 newborns were entered in the study. For each infant, severe hyperbilirubinemia (total serum bilirubin equal or greater than 300 micromol/L) was tested by the diazo method and G6PD was evaluated by Fluorescent Spot Test (FST). Of all infants, 15 (1.4 %) were diagnosed to have G6PD deficiency by FST. The prevalence of G6PD deficiency was significantly in boys higher than in girls (80% vs. 20%, p=0.001). Of all infants, 97 (9.3%) had jaun dice 72 hours after birth that of them 7 neonates (7.2%) had G6PD deficiency. Results showed that the prevalence of G6PD deficiency in this study was less than in other places in Iran that may be because of different ethnicity and demographic features.

Introduction: Quality of life (QOL) is an important index in society that need for evaluation in all age groups people especially in medical university students as a people that their physical and mental health is related with community health. This study aims to investigate the quality of life (QOL) of Ardabil University of Medical Sciences. Methods: This is a cross-sectional study that has been conducted on 200 students who selected by random sampling method from Ardabil medical university students. The QOL was measured by WHOQOL-BREF which its validity and Reliability were investigated and approved. This questionnaire include 26 questions in four dimensions (physical, mental, social and environmental health). Collected data we analyzed by statistical test such as t-test for compare the mean of QOL score among demographic data. Results: Of all students, 57% were male and 91.5% were single. Of all students, 56% had desired quality of life. The relationships between QOL and variables such as gender, educational level, marital status and age of students wasn’t significant. The mean difference of four dimension scores among two sexes was statistically significant. The mean of Physical health dimension score was 11.6±2.1, Psychological was 12.3±2.4, Social relationships was 13.1±3.4 and environment was 12.7±3.2. The mean of total score of QOL in all students was 12.4±2.3. Conclusion: Results showed that the QOL of all students were in high level and in four dimension of QOL the female students had significant higher score than male students.
