Abstract
Background & Objective: Preeclampsia is an unknown disease. It was seen in 3.7% of live births and it is the cause of mothers' death in 18%. In addition to complications for mothers, fetal damage have also been seen. Also we sought to consider predictors of neonatal outcome in women with preeclampsia and normal women. Methods: It is a prospective and cross-sectional study that was performed on 127 preeclampsia pregnant women and 254 normal pregnancy. Statistical analysis was performed by software SPSS/Win and was used X2 test for analysis of the results. Results: Prevalence of preterm labor was 54.4% in women with preeclampsia and 25% in normal pregnancy. There was no statistical difference such as parity (P=0.157), age (P=0.256) and type of delivery (P= 0.226). There was a significant difference between two groups in gestational age (P<0.0001), birth weight (P<0.0001), neonatal mortality (P=0.013), neonatal Apgar score (P=0.005) and NICU admission (P<0.0001). Conclusion: It is clear that the difference between two groups is mainly because of preterm labor in preeclampsia group. Attention to exact control of illness and avoidance of making rash decision for terminating pregnancy in mild preeclampsia can improve outcomes of Neonates.

Abstract
Background & Objectives: Different types of diets and several chemical and herbal drugs are used for decreasing the fasting blood glucose, glycosylated hemoglobin and insulin resistance in type II diabetic patients. New herbal medicines including cinnamon have been considered for controlling diabetes. Since few reports have been presented in other countries and many studies have been done in animal models in laboratory condition, this study was aimed to investigate cinnamon supplementation effects on fasting blood glucose, glycosylated hemoglobin and insulin resistance among type II diabetic patients . Methods: In a clinical trial study, 60 male and female patients with type II diabetes mellitus (30 patients in control and 30 patients in treatment group) were selected in Tabriz city, during 1388. The intervention group received 1.5 g of cinnamon (as a capsule containing 500 mg powder, three times daily) for 60 days and control group received placebo. Blood samples obtained from patients to determine the levels of fasting blood glucose, the glycosylated hemoglobin and insulin, before and after cinnamon consumption. Insulin resistance was measured by HOMA score and data were expressed as Mean ± SD and analyzed statistically by Student t-test. p<0.05 was considered as significant . Results: After 60 days, the fasting blood glucose levels, the glycosylated hemoglobin and the insulin resistance decreased significantly in the intervention group compared to controls (p<0.05). There was no significant change in the fasting blood glucose levels, the glycosylated hemoglobin and the insulin resistance in the control group at the end of 60 days. Conclusion: This study showed the consumption of cinnamon can be useful in the fasting blood glucose, the glycosylated hemoglobin and the insulin resistance control among type II diabetic patients .

Abstract
Background & Objectives: Nowadays, appearance of ESBL producing bacteria is medical problem in the treatment of infections. Uropathogenic Escherichia coli like many other bacteria can produce these types of enzymes. T he assessment of the ESBL production by clinical isolates is not done routinely in laboratories. The aim of this study was to determine the prevalence of ESBL producing E.coli and its antibiotic resistance pattern in Kermanshah. Methods: This cross - sectional study was done on 200 Uropathogenic E. coli strains isolated from people in Kermanshah. Sensitivity of isolates to different antibiotics was determined by disk diffusion test and ESBL production was assessed by DDST method. Results: The E. coli strains showed high susceptibility to imipenem (100%), amikacin (97%), nitrofurantoin (95.5%), gentamicin (85%), cefepime (75%), ceftazidime (74%), ofloxacin (73.5%), ciprofloxacin, ceftriaxone and aztreonam (71%) and cefotaxime (70%) respectively. The highest resistance was seen to ampicillin (77%), carbenicillin (76%), pipracillin (74%) and SXT (62.5% ). Resistance rate to third generation cephalosporins was 63-75%. Fifty seven isolates (27%) were ESBL producers and 47 isolates (87%) produced all four types of ESBL enzymes. Conclusion: There are some similarities and differences in the antibiotic resistance pattern and ESBL production among the isolates in different areas of Iran and other countries. Identification of ESBL producing bacteria and determining its antimicrobial resistance pattern are recommended to effective treatment of infections.

Abstract
Background & Objectives: The first Laparoscopic Cholecystectomy surgery was performed by Erich Muhe in 1985.Nowadays in developed countries, more than 90% of cholecystectomy surgeries are done by Laparoscopic method and it is one of the most common elective surgeries. The aim of this study is to evaluate the frequency and side effects of this method and the rate of conversion to open surgery patients undergoing laparoscopic cholecystectomy surgery in Sabalan and Arta hospitals in Ardabil province. Methods: This descriptive analytical study was performed between October 2006 and January 2009. We have studied 200 patients (24 male, 176 female) with cholecystitis (symptomatic gallstones) treated by Laparoscopic Cholecystectomy surgery. Data were collected through questionnaires and telephone calls (at least 6 months after surgery). Data analysis was done by SPSS statistical software and chi-square test. p<0.05 was considered as significant. Results: The average age of patients was 44.6 years. In the final diagnosis, 168 patients (84%) had chronic cholecystitis and 32 patients (16%) had acute cholecystitis. The rate of conversion to open surgery was 8 patients (4%). Eight cases (4%) were suffered organic side effects including: four cases (2%) jaundice after surgery, 1 case (0.5%) postoperative fever, 1 case (0.5%) leakage of bile, 1 case (0.5%) slight leaking of serum from the surgical site and 1 case (0.5%) associated with increased liver enzymes that had no other symptoms. About the risk factors for conversion to open surgery, there was significant correlation between acute cholecystitis and male gender. Information about the satisfaction of patients after surgery showed that, 89.5% were completely satisfied, 2.5% were completely dissatisfied and 8% were relatively dissatisfied. No deaths were seen. Conclusion: Laparoscopic Cholecystectomy is a standard selective treatment method for gallbladder stones. It has many advantages including reduced duration of hospitalization, less pain, reduced morbidity and less side effects than open surgery, lower recovery period and faster return to normal life.

Abstract
Background & Objective: Currently, migration of rural population to cities and developing slums around them are main problems in population settlement that lead to imbalance in health standards such as difference in age groups death. The aim of this study was to examine factors associated with infant mortality in slums of the Ardabil city. Methods: This was a case- control study. All infants’ deaths from 2008 to 2010, which occurred in slums as a case, were included. For each case, tow controls, were chosen. Controls the ones who survived and were living in non marginalized area and years of birth and sex were matched in two groups. Information collected from health centers through questionnaires, interviews with parents and child death files. Results: The majority of mortalities (74.6%) were in neonatal period and 25.4% was in post- neonatal period. The most important causes of deaths in neonatal were prematurity (57%), and in post neonatal period were congenital abnormality (35.4%). Analysis of effective factors showed that birth weight, parents age and education, family income and occupation and smoking of father were highly associated with mortalities. Conclusion: Infant mortality of the family that their father is a smoker and they have low income, and low parental education level is significantly higher and should be taken into serious consideration to reduce the mortality.

Abstract
Background & objectives: In recent years, Acinetobacter baumannii has been shown to be associated with several nosocomial infections, including pneumonia, bacteraemia, urinary tract infections, wound infection and meningitis. This organism can survive in the hospital environment and rapidly develops resistance to many antibiotics. The molecular genotyping can increase our knowledge about the spread of A. baumannii strains from one hospital to another and their drug resistance. Therefore, this study aimed to determine the prevalence of antibiotic resistance profile as well as phylogenetic relationships of A. baumannii strains in Shahrekord teaching hospitals.
Methods: In this study, antibacterial susceptibility patterns of A. baumannii strains isolated from different clinical specimens (urine, blood, sputum) to amikacin, ampicillin/sulbactam, aztreonam, cefepime, ceftazidime, ciprofloxacin, gentamycin, imipenem, meropenem, norfloxacin, ofloxacin, piperacillin/tazobactam, tobramycin were tested using disk diffusion )Kirby-Bauer( method. Finally, genotyping of A. baumannii strains was performed using REP-PCR method.
Results: During this study, 50 samples of patients were identified as A. baumannii) 71%(, and their drug resistance rates were assessed. All A. baumannii strains were resistant to ceftazidime and cefepime and also a high rate of resistance to aztreonam, norfloxacin, ciprofloxacin, amikacin, imipenem, gentamycin, and ampicillin-sulbactam were observed. On the other hand, our results demonstrated nine genotype groups among A. baumannii strains based on REP-PCR method.
Conclusion: Due to the high prevalence of antibiotic resistance among isolated A. baumannii strains, similarities between different genotypes and the dispersion of these genotypes in different parts of Shahrekord hospitals, the implementation of infection control programs in different parts of the hospital is necessary.

Abstract
Background and objectives: Urinary tract infection (UTI) is the most prevalent infection and Escherichia coli (E. coli) is one of the main causes of UTI worldwide. Integrons are mobile genetic elements considered to be responsible for dissemination of multi-drug resistance infections. Therefore, the aims of this study were to investigate the antibiotic resistance patterns and distribution of class I, II and III integrons among E. coli isolated from patients.
Methods: In this descriptive cross-sectional study, from Jun 2020 to March 2021, in total, 70 non-duplicate strains of E. coli were isolated from patients with UTI referred to Amiralmomenin hospital, Zabol, Iran. Antibiotic resistance patterns were determined using Kirby-Bauer’s disk diffusion method and Clinical and Laboratory Standards Institute (CLSI) guidelines. Class I, II and III integrons were detected using polymerase chain reaction (PCR).
Results: The isolates showed high resistance toward ampicillin (77.1%), trimethoprim- sulfamethoxazole (58.5%) and ceftriaxone (35%), whereas were mostly susceptible to meropenem (97%). Based on results of PCR, 34 (48.6%) and 3 (4.3%) isolates were classified as class I and class II integron-positive strains, respectively.
Conclusion: Resistance rate to ampicillin, ceftriaxone and trimethoprim-sulfamethoxazole was at a high level and their prescription should be restricted. Class I integron is widely distributed among E. coli isolates and play a crucial role in the emergence of antibiotic resistance

Abstract
Background & objectives: Carbapenems are the main antibiotics for the treatment of infections caused by multidrug-resistant (MDR) Pseudomonas aeruginosa (P. aeruginosa). The aims of this study were to determine the prevalence of gene encoding outer membrane porin protein (OprD) in carbapenem-resistant P. aeruginosa strains as well as to assess the role of insertion sequence (IS) elements in the inactivation of OprD porin and the emergence of carbapenem resistance.
Methods: In this study, 103 clinical isolates of P. aeruginosa including 58, 42 and 23 strains resistant to imipenem, meropenem, and doripenem were used, respectively. The isolates were collected from patients referred to Ardabil hospitals. The presence of oprD gene and IS elements were investigated using polymerase chain reaction (PCR) and sequencing methods. P. aeruginosa PAO1 standard isolate was used as the positive control strain for oprD gene.
Results: The frequency of oprD gene among carbapenem-resistant P. aeruginosa strains isolated from Ardabil hospitals was 96.5%. Furthermore, IS elements were not observed in the investigated isolates.
Conclusion: Based on the results of this study, the presence of IS elements did not involve in the inactivation of outer membrane porin OprD and resistance to carbapenems among P. aeruginosa clinical strains in Ardabil. Therefore, an investigation of the role of other mutations in reducing the expression of oprD gene and increasing P. aeruginosa resistance to carbapenems is recommended.

Abstract
Background: Antibiotic resistance represents a critical global concern within the medical community, posing significant challenges in the treatment of infections caused by drug-resistant pathogens. Over the years, broad-spectrum fluoroquinolones have been extensively used to treat infections caused by both Gram-positive and Gram-negative bacteria, including Pseudomonas aeruginosa. In this study, we decided to assess the prevalence of plasmid-mediated quinolone resistance mechanisms among clinical isolates of P. aeruginosa in Ardabil hospitals.
Methods: We analyzed a total of 200 clinical isolates of P. aeruginosa, collected between June 2019 and May 2023. The antibiotic resistance profiles of these strains against various fluoroquinolone antibiotics were determined using the disk diffusion method. Additionally, we investigated the presence of qnrA, qnrB, qnrC, qnrD, and qnrS genes through polymerase chain reaction (PCR) analysis. Furthermore, we assessed the expression levels of efflux pump genes and outer membrane porin genes using the quantitative reverse transcription PCR (qRT-PCR) in fluoroquinolone-resistant P. aeruginosa strains.
Results: Our findings revealed that 69% of P. aeruginosa strains were resistant to fluoroquinolones. The resistance rates for different fluoroquinolones were as follows: ciprofloxacin 55.5%, ofloxacin 62%, norfloxacin 53.5%, lomefloxacin 55.3%, and levofloxacin 55.5%. Notably, 78.9% of these strains exhibited multidrug resistance (MDR). Among the qnr genes, qnrB was the most prevalent (2.9%). No other qnr genes were identified. Interestingly, 75% of P. aeruginosa strains carrying the qnrB gene showed overexpression of efflux pump genes, while 100% exhibited down-regulation of the oprD gene.
Conclusion: Given the high prevalence of fluoroquinolone-resistant P. aeruginosa clinical isolates in Ardabil hospitals and the multifactorial nature of resistance, continuous monitoring of antibiotic resistance trends and understanding the underlying resistance mechanisms are crucial for selecting appropriate treatment strategies.
