Abstract
Background: In 2-4% of couples in fertile ages, recurrent pregnancy loss (RPL) occurs which consisted one out of 300 pregnancies. The aim of this study was to comparison insulin resistance (IR) in patients with RPL to normal individuals.
Materials and Methods: In a case-controlled, prospective study, 49 non-pregnant, non-diabetic women with early RPL as the case group and 49 non-pregnant, non-diabetic women without RPL who had at least one live infant as the control group, and were matched by age, weight, and height, were enrolled. In both groups fasting insulin and glucose levels were measured and insulin resistance, which was defined as a fasting insulin (FI) level ≥20 microU/mL or a fasting glucose to insulin ratio (FGI ratio) of <4.5, was calculated.
Results: The RPL and control groups were similar with respect to age, BMI, fasting glucose levels and glucose to insulin ratios. FI was significantly higher in RPL group than control group (15.20±5.82 vs. 12.23±5.64 microU/mL). Also the frequency of patients with high FI (FI≥20µU/ml) in RPL group was significantly higher than in control group (22.45% vs. 6.12%, Odds Ratio=4.44, Confidence Interval 95%=1.15-17.07). Among the RPL group, 24.49% demonstrated insulin resistance, whereas only 8.16% of the matched controls were insulin resistant (Odds Ratio=3.65, Confidence Interval 95%=1.08-12.26). The RPL and control groups had similar in frequency of low FGI ratio. Also there was no significant difference between mean of FGI ratio in patients with fewer than 12 weeks miscarriage compared to over 12 weeks in RPL group.
Conclusion: Women with RPL have a significantly increased prevalence of insulin resistance when compared with matched fertile controls. It's recommended that in all women with RPL the glucose and insulin measurement should be carried.

Background: The
prevalence of Rh alloimmunization has decreased following the use of anti-D
immunoglobulin. With serial amniocentesis, Doppler sonography of the middle
cerebral artery and treatment of anemia with intrauterine blood transfusion, perinatal
mortality has declined. However, Rh alloimmunization in twin pregnancies poses
a diagnostic and therapeutic challenge.
Case report: We are reporting,
for the first time in Iran, the successful treatment of severe Rh
alloimmunization in a dichorionic- diamnionic twin pregnancy leading to the
live births of both neonates. Before treatment, the fetal hemoglobin levels
were 3.1g/dL and 3.9g/dL, with ascites in both fetuses. The fetuses were
treated with several IUTs.
Results: After treatment, the neonates were
delivered, weighing 2200 and 2300g, with good Apgar scores, at a gestational
age of 34 weeks.
Conclusion: 10%
of population in Iran is Rh-negative, although Prophylaxis for Rh
alloimmunization is universal, as other part of the world it cannot irrigated.
For the best management of these cases, we need a well-equipped referral
center.

Abstract
Background: Beta- lactamase enzymes are the most important resistant factors to beta lactam antibiotics among gram negative bacteria. Nowadays, the prevalence of beta- lactamase infection is increasing worldwide and drawn the scientists attention as an important subject. Due to high prevalence of bacteria contained TEM beta lactamase and AmpC enzymes, using molecular methods especially designing universal primers could be valuable to detect all of them. The aim of this study was to determine the prevalence of TEM and AmpC (Dha and MOX) beta- lactamase genes using universal primers.
Methods: A total of 500 clinical specimens from various Hospitals in Tehran, Iran were collected and analyzed for E. coli based on biochemical tests. These clinical specimens were also screened by Disk diffusion agar, combined disk method and PCR to detect the samples producing extended- spectrum beta- lactamase.
Results: Overall 200 isolates of Escherichia coli were collected from the 500 clinical specimens out of which 128(64%) isolates were positive by PCR assay and showed bla- TEM, bla- AmpC (Dha, MOX) genes, 74(57.8%) and 5(3.9%) to have bla- TEM and bla Dha, respectively. Mox gene was not detected in any of the specimens.
Conclusions: Our results revealed that using the molecular methods with phenotype methods is very essential for complete detection of Beta- lactamases. There is the need for updating the treatment protocol because the prevalence of this resistance is increasing.

Abstract
Background: Resistance to beta-lactam antibiotics in clinical isolates frequently results
from the production of β-lactamase enzymes. In recent years, the production of extended spectrum β-lactamases (ESBLs) and AmpC β-lactamase have greatly increased, especially in clinically isolated Escherichia coli. On the other hand, beta lactamase genes have several subfamilies and designing universal primers could be valuable in their detection. The beta-lactamase-producing E. coli which is resistant to beta-lactam antibiotics may pose a great risk to the patients. The CTX-M-1 gene is responsible for beta lactamase resistance. The purpose of this study was to find the percentage of CTX-M-1 carrying E. coli strains.
Methods: A total of 500 urine samples were collected from different hospitals in Tehran, Iran during September to February 2009. The samples were cultured on EMB agar and incubated at 37 C for 24 hours. Some biochemical tests were carried out on
the isolated samples. The presence of CTX-M-1 gene was determined by PCR on the
isolates already identified phenotypically by disk diffusion agar and combined disks. Results: In general, 200 out of the initial 500 samples were identified as E. coli, among which 128 (79.5%) were ESBLs producing strains. PCR used for the detection of CTX-M-
1 gene, showed that 99 (77.34%) out of 128 isolates contained such gene.
Conclusion: The results of this study showed a high percentage of β-lactamase resistant E. coli strains. This is a serious matter and would pose a public hazard and every step should be taken to avoid such hazard.

Abstract
Background: Numerous use of Beta Lactame in treatment of bacterial infections resulted in increments of drug resistance of such bacteria. One of difficulties in treatment of hospital infections is Extended Spectrum Beta Lactamase (ESBL) among isolated clinical strains of E.coli. Since some of ESBL strains shows double reaction in drug sensitivity test at in vitro and in vivo condition, therefore it makes difficulties in selection of right treatment. In the last years, CTX-M enzymes have become the most prevalent ESBLs in worldwide. The prevalence of ESBL types largely remains unknown in many parts of the Iran. This study was made to find the prevalence of ESBL-producing E.coli and molecular detection of CTX-M-1 in Tabriz.
Methods: In the present study, 400 urine samples collected between November 2009 and April 2010, from Tabriz Hospitals were studied. Out of the 400 samples, 188 E.coli isolates were detected by standard biochemical tests. Susceptibility to antimicrobial agents was tested to 10 antibiotics by the disk agar diffusion (DAD) method. ESBL production was screened by phenotypic test that included both separate and combined disk agar diffusion techniques. The screened isolates were investigated by PCR assay to detect CTX-M-1 gene.
Results: From the total 188 E.coli isolates, 82 (43.6%) were shown to produce ESBLs by phenotypic test. During the PCR method on the 82 isolates, 69 (84.1%) were confirmed as CTX-M-1 producing group.
Conclusion: The present study showed that CTX-M-producing isolates were increasing among E.coli strains and indicated the need for adequate susceptibility tests in laboratories for choosing the appropriate antibiotics for treatment.

Abstract
Background: The rabies is a deadly disease and if its symptoms break out in a person, he will certainly die. However, the deaths caused rabies can be prevented by post-exposure prophylaxis (PEP).
Methods: In this study, subjects were recruited through census and with respect to in-formation which gathered from Fars Province health centers, Pasteur institution and previous studies In Iran. The mortalities for age groups and by sex type have been cal-culated. The decision tree model using probabilities, which the effectiveness of PEP treatment after getting bitten by an animal suspected, persons to receive specified. Dis-ability adjusted life year score (DALY) was applied to estimate the DALYs saved from PEP. In this study it was assumed that if a person suffering with rabies, a few days af-ter the onset of symptoms, death is compulsory. Therefore YLD rabies was considered zero. Finally, to increasing the accuracy and because inherent uncertainty of the data, and the increase the power of analysis, one-way sensitivity analysis was used.
Results: From March 2011 to March 2012, in Fars Province, total cases of animal bites were reported and received PEP treatment. The cases were 5394 (75.85%) male and 1717 (24.15%) female. PEP generally prevented from 177.076 deaths which 134.096 (75.72%) were men and 42.98 (24.27%) of them were women. The age distribution of suspected animal bites in youth more than adults, and in men higher than women. Also due to prevented mortality caused by PEP, it is prevented from 4455.71 DALYs. Based on the sensitivity analysis DALY prevented, except for dogs and cats, there was no change in the other animals.
Conclusion: The implementation of PEP for animal bitten people remarkably reduced the burden of disease in community. Calculations with primitive cost estimations im-plicitly revealed that this intervention is a most cost-effectiveness program.

Abstract
Background: Hypertension is one of the most important chronic illness worldwide and one the major risk factors for cardiovascular diseases. Obesity and abdominal obesity are risk factors for high blood pressure. Population attributable fraction (PAF) answers the question of how much of the disease burden in a certain population may be reduced if a risk factor like obesity is removed from the population. It implies that reducing prevalence of obesity as a risk factor of hypertension, may reduce the burden of hypertension and its consequences. The aim of this study was to determine the population attributable fraction of hypertension associated with obesity, abdominal obesity and joint effect of them in the men of Mazandaran Province, North of Iran.
Methods: In this epidemiological study, the data of non-communicable disease surveillance system in 2009 has been achieved. Then measure of association between obesity and hypertension (Odds Ratio) was extracted from Tehran Lipid and Glucose Study (TLGS). After standardizing the data, the population attributable risk for men based on the above formula (Levin's attributable fraction formula) has been calculated.
|
Results: In our study based on population attributable fraction, results in blood pressure caused by obesity were 14.5 (CI 95%: 10.7-17.2), the effect of abdominal obesity was 7.4 (CI 95%: 2.04-11.3) and deductions attributable joint effect both obesity and abdominal obesity was 22.6 (CI 95%: 9.7-25.6) respectively.
Conclusion: Given the high prevalence of hypertension and obesity in Mazandaran men and the impact of obesity on blood pressure is necessary to prevent the spread of the disease. It is recommended that health promotion programs focus on men with high blood pressure due to obesity could be performed.

Abstract
Background: Children's health, preserving and promoting it is a health priority of any society. Malnutrition affects all age groups, but malnutrition in children is one of the most common nutritional problems that can delay body growth, shortened height, frequent infections, mental retardation, the prevalence of mental disorders, lack of academic achievement and reduced efficacy. Because of the importance and impact of this issue in children, the purpose of this study was a systematic review and meta-analysis of the prevalence of underweight in Iranian children, in order to highlight the importance of this issue to health policy-makers.
Methods: A meta-analysis was performed for relevant articles in scientific databases including Scientific Information Database (SID), ScienceDirect, PubMed and Google Scholar. Entrance criteria included cross-sectional studies (March 1996 to February 2017) that had a low incidence of underweight in Iranian children in different parts of Iran. Non-relevant articles included review articles, interventions, cohorts and case studies, and studies that looked at obesity, overweight and the relationship between these factors and other diseases, excluded from the study list. Reference lists of identified articles were reviewed for additional articles. Heterogeneity of study was checked using I2 index and the possibility of publication bias by funnel plot and Begg and Mazumdar's rank correlation test and a significance level of 0.1. Data were analyzed using the comprehensive meta-analysis software, version 3 (Biostat, Englewood, NJ, USA).
Results: In 26 articles reviewed in the study, total number of participants was 142938 persons at the age of 1 month to 12 years. The overall prevalence of underweight in Iranian children was 15.5% (Cl 95%: 12%-19.7%) during 1996 to 2017. The highest prevalence of underweight in was recorded in Birjand city in 2006 and Zahedan city in 2009, 68.6% (Cl 95%: 63.3%-72.9%) and the lowest prevalence of underweight in was found in city of Jahrom in 2013, 1.8% (Cl 95%: 1.2%-2.9%).
Conclusion: According to the results of this study, the prevalence of low-birth-weight in the country is high and requires interventional measures.

Abstract
Background: The rate of recurrence and mortality in high-risk prostate cancer remains high. On the other hand, the use of chemotherapy in metastatic prostate cancer has improved overall survival of patients. The aim of this study was to evaluate the effect of neoadjuvant chemotherapy alone on increasing survival of patients with high risk localized prostate cancer
Methods: This is a systematic review study. Databases including Scopus, Medline, PubMed, Google Scholar, Cochrane, Embase were searched. The terms used include prostate cancer, adenocarcinoma, neoadjuvant, chemotherapy, chemotherapy alone, systemic therapy. Of the various types of articles, only oiginal research studies that specifically focused on neoadjuvant chemotherapy (not chemotherapy with target therapy, immunotherapy, or hormone therapy) were identified. Inclusion criteria included study type (original research studies) and sample type (high-risk localized prostate cancer patients) and outcome type (patient survival).
Results: A total of 17 original research studies were identified. All of these studies were phase one or phase two. Docetaxel was the most commonly used chemotherapy drug. Also, the most common regimen used was the use of docetaxel alone. The rate of decrease in prostate-specific antigen (PSA) (>50%) after neoadjuvant chemotherapy was reported in 24 to 58% of patients. PSA declines of less than 50% after neoadjuvant chemotherapy occurred in 40 to 100% of patients. No studies reported a complete pathologic response following neoadjuvant chemotherapy. However, the relative pathologic response and reduced tumor volume were seen in the majority of patients. All of these studies showed that neoadjuvant chemotherapy alone, in high-risk prostate cancer patients, was almost well tolerated and that the complications were mostly mild (grade 1 and 2). Grade 3 and 4 complications were negligible. A 2-year recurrence-free survival of up to 68.5% and a 5-year recurrence-free survival of up to 49% were reported. The overall 5-year survival also ranged from 35 to 48%.
Conclusion: The use of neoadjuvant chemotherapy alone has not clearly increased the survival of patients with high-risk localized prostate cancer, and there is controversy in studies.

Abstract
Background: Approximately 3% to 5% of obstetric patients will experience postpartum hemorrhage (PPH). Even though the most common reason for postpartum hemorrhage, as the main cause of maternal death, is uterine atony; other complications such as laceration, hematoma, inversion, rupture; retained tissue or invasive placenta; and coagulopathy may result in PPH. The main cause of retained placenta can be traced to the history of manual placenta removal, violent and numerous curettages, uterus anatomical abnormalities, placenta accreta or placenta previa, and history of cesarean section. Here, we have presented a case of retained placenta and uterus septum.
Case Presentation: The patient, a 36 years old female, multigravid 11 live 3 ,death 1 and abortion 6, with a history of four normal vaginal deliveries, and history of preterm premature rupture of membrane since the 16th week of pregnancy, was admitted to Imam Reza hospital, Mashhad University of Medical Sciences due to labor pain in 29th week of pregnancy. After a vaginal delivery, she was transferred to the operating room due to a retained placenta. During the initial diagnosis, the patient’s cervix was dilated and manual placental removal was not possible. The ultrasound results showed an 80mm heterogeneous tissue in the fundus, extending to the left cornu. There was no sign of accreta. During hysterotomy, the retained placenta was removed from underneath a thick layer of Uterine Septum, using sponge forceps. Five days later, the patient returned with severe pelvic pain and signs of peritonitis. Laparotomy and hysterectomy were performed on account of uterine incision necrosis.
Conclusion: The most crucial step in the treatment of retained placenta lies in the early detection of its cause. The treatment includes manual or Surgical removed of placenta which can result in bleeding, infection, and a lengthy recovery.

Abstract
Background: Considering the high prevalence of breast masses and the importance of screening and follow-up for malignancies in women, and since age and hormonal changes during menopause play a role in determining the type of pathology and prognosis of the masses, the purpose of this study is to determine the relationship between menopause and mass pathology.
Methods: This was a cross-sectional-analytical study that was conducted in order to investigate the types of pathology of breast masses and their relationship with the age of menopause in women referred to Shahid Beheshti Hospital in Qom between April 2013 and April 2019. The inclusion criteria include: having sufficient file information and having a contact number to complete personal information, no history of cancer in other parts of the body and simultaneous malignancies, and the exclusion criteria also include: samples that were taken by cellular aspiration sampling, There were women who had a history of first-degree breast malignancy and were previously diagnosed with breast cancer and there was a possibility that the new mass under study was metastatic. Finally, the patients' information was extracted from the files and recorded in pre-prepared checklists. And the supplementary information of the incomplete files was asked and completed using the contact information of the patients. After collecting the information, using SPSS software version 26 and with chi-square and t-test statistical tests and considering the significance level of 0.05 the data was analyzed.
|
Results: He prevalence of malignancy in postmenopausal women was higher than in premenopausal women. Also, a significant difference was found between tumor size, the presence or absence of metastasis, and menopause (P<0.05), but no significant difference was found between tumor location and menopause (P>0.05).
Conclusion: Breast malignancies (invasive ductal carcinoma, invasive mixed carcinoma, mucinous, medullary, and papillary carcinoma) were more common in postmenopausal women than non-menopausal women. In both groups, ductal dilatation and chronic inflammation were the most benign findings, and fibroadenoma was found at a much lower rate in menopausal women than in non-menopausal.
