Abstract Introduction Prophylactic chemotherapy (PC) has been suggested to be effective in prevention of post molar gestational trophoblastic neoplasia (PGTN) in patients with high-risk molar pregnancies. The goal of this study is to assess the efficacy of single dose methotrexate as PC in terms of spontaneous remission, time to remission, and progression to PGTN. Materials and methods Patients with molar pregnancy were recruited to the study and underwent cervical dilation and suction curettage. Patients who had pathologically proven complete hydatidiform mole were evaluated with abdominal ultrasonography to confirm complete evacuation and absence of remnants. These patients were allocated to two groups: group one received Methotrexate 50 mg/m2 via intramuscular injection, while group two did not. PGTN was defined according to the 2018 FIGO criteria. For patients with confirmed PGTN, the following variables were recorded: occurrence of metastasis, resistance to first-line chemotherapy and time to βHCG level normalization. Results Eighty patients were enrolled to the study, of which 22 cases (27.5%) received PC. It was found that PC with MTX did not significantly influence spontaneous remission (18 (81.8%) Vs 37 (63.7%), p value: 0.12) or time to remission (57 ± 22.5 Vs 61.24 ± 21.78 days, p value: 0.46) in high-risk molar pregnancies. Moreover, among patients in PC group and control group, 4 cases (18.2%) and 21 patients (36.3%) progressed to PGNT, respectively (p value: 0.12). Although patients in PC group tended to be diagnosed in lower stages compared to patients in control group, this difference was insignificance (p value: 0.95). Among patients who developed to PGTN, PC did not reduce the frequency of metastatic disease, resistance to first-line chemotherapy, or the time interval to serum βHCG level normalization (all p values > 0.05). Conclusion This study suggests that a single-dose MTX as PC may not be an effective therapeutic option for preventing PGTN in patients with high-risk molar pregnancy.

Objective: To assess the impact of a hysteroscopic myoma resection (HMR) two-day training course on non-technical (cognitive) surgical skills among gynecologists. Materials and methods: A 2-day educational course was held in which 95 consultant gynecologic surgeons and beginner infertility fellowship residents took part. Among all 80 participants (84.2%) had ever performed diagnostic hysteroscopy and 30 (31.3%) had performed non-resectoscopic operative hysteroscopy. The training program included instructive speeches, simulated surgical presentations, and a live hands-on myomectomy workshop. Non-technical skills were assessed two times, once before and the other after the course through two written tests with 10 multiple-choice questions for each. Results: Concerning the 95 participants, 43 (47.3%) took the pre-course test and all of them (100%) took the post-course one. The mean score improved significantly from 3 (interquartile range [IQR], 0–4.0) to 7 (IQR, 5.0– 8.0) [bootstrap p

Objective: Dual oxidases (DUOX1, DUOX2) belong to the NADPH oxidase (NOX) family, which produce H2O2 necessary for thyroid hormone biosynthesis. This study aims to evaluate gene expression for DUOX1, DUOX2 in PCOS patients and its relation with thyroid hormone and magnesium levels. Materials and methods: Totally 88 cases were studied including 24 people with PCOS and hypothyroidism, 44 people with PCOS and normal thyroid function, and 20 hypothyroid patients without PCOS. In comparison 40 healthy controls in the age group of 16-35 years matched for age group and BMI were evaluated. Using Vegaro syringe 5 cc of blood was sampled from all 128 people and after RNA extraction and cDNA synthesis using Real-Time PCR technique, the expression level of DUOX1 and DUOX2 genes was investigated. Results: The results of hormonal tests showed that there is a significant difference between the level of T4, T3, and TSH hormones in hypothyroid patients with or without PCOS in comparison to the control group. Regarding the level of Mg, the results showed that there is a significant difference between the levels of Mg in PCOS group with or without hypothyroidism in comparison to the control group. Gene expression results showed that the relative changes of DUOX1 gene expression in different groups compared to the control group were significantly reduced P

Abstract Background Epithelial ovarian cancer (EOC) is an extremely aggressive and lethal carcinoma. Specific data that identify high-risk groups with uterine involvement are not available. Thus, this study aimed to evaluate a gross number of women with EOC to obtain the frequency of uterine involvement and its risk factors. Methods This retrospective observational study was conducted on 1900 histologically confirmed EOC women, diagnosed and treated in our tertiary hospital from March 2009 to September 2020. Data including their demographic, medical and pathological findings were collected. Results From 1900 histologically confirmed EOC women, 347 patients were eligible for participations. The mean age of study patients was 51.31 ± 11.37 years with the age range of 25 to 87 years. Uterine involvement was detected in 49.6% (173) of the patients either macroscopic (47.4%) or microscopic (52.6%) types. Uterine involvement was significantly associated with having AUB (P-value = 0.002), histological type of ovary tumor (P-value

Objective: Breaking bad news to the patient is challenging, especially for the physicians and the residents, due to the lack of structured and practical training. This study aimed to design and evaluate a novel virtual instructional design for improving obstetrics and gynecology (Ob/Gyn) residents breaking bad news skills. Materials and methods: Virtual instructional design was performed based on the ADDIE model (Analysis, Design, Development, Implementation and Evaluation) from September 2020 to July 2021 at the Department of Ob/Gyn, a referral hospital affiliated with Tehran University of Medical Sciences, Tehran. Iran. The five steps of ADDIE virtual instructional design were applied sequentially. Results: Totally 33 of the Ob/Gyn residents included in the study that 77% needed specific training. The awareness of the performance of the residents in seven areas including interview context, strategy, planning, professionalism, empathy, knowledge, and receiving information needed to be trained for breaking bad news. The content of the virtual training package was designed based on the prior assessment needs in four multimedia lectures of professors, one short educational video, a 65-page file that combines text and images in 4 parts. The pre-test and post-test mean scores (SD) were 9.45 (2.0) and 10.67 (1.7), respectively (p-value≤0.001) in the cognitive and attitudinal domain. In the final step, the final corrections were made in the virtual training package. Interestingly, the satisfaction of residents' attitudes was 96.5%. Conclusion: Most Ob/Gyn residents do not have the necessary perception and skills to deliver bad news to the patients. Designing an appropriate virtual training package for improving communication skills is associated with satisfaction. Thus, the efficacy of the training program should be implemented for all Ob/Gyn residents.

Abstract Background Cervical cancer is one of the most common malignancies among women. Appropriate and timely treatment of these patients can reduce the complications and increase their survival. The objective of this study was to compare neoadjuvant chemotherapy plus radical hysterectomy (NACTRH) and chemo-radiotherapy (CRT) in patients with bulky cervical cancer (stage IB3 & IIA2). Material and methods The medical records of patients with bulky cervical cancer (stage IB3 & IIA2) that received NACTRH or CRT between 2007 and 2017 were evaluated for therapeutic effects. Demographic characteristics, complications of chemo-radiotherapy and neoadjuvant chemotherapy, were collected in a researcher-made questionnaire. Our primary outcome was comparison of overall survival (OS), and disease-free survival (DFS) between two groups receiving NACTRH and CRT modalities. Results One-hundred and twenty three patients were enrolled in the study. The median age and the proportion of patients with stage IIA2 were higher in the CRT group compared to the NACTRH group (p

Objective: The coronavirus disease 19 (COVID-19) is a highly transmittable and pathogenic viral infection, causes severe acute respiratory syndrome and was spread throughout the world in early 2020. The effects of vitamin and micronutrient supplements on the prevention and treatment of COVID- 19 seems challenging in scientific considerations. On the other side generally, experts warn against over-consumption of these supplements. Materials and methods: This study aimed to investigate the vitamin and micronutrient supplementation usage pattern in past history of patients with COVID-19 via a cross-sectional inquiry. Totally 510 patients referring to the infectious disease clinic of Imam Khomeini Hospital in Tehran from March 2020 to May 2020 were recruited. The inclusion criterion was suspected patients for COVID-19 based on clinical findings and CT scans of the lung. The infected patients included both inpatients (171) and outpatients (339). Demographic information, clinical signs, and the supplement pattern use were collected through a questionnaire and the data were statistically analyzed. Results: Vitamin D3 intake was reported in 30% (103 patients) of outpatients and 16.5% (28 patients) of hospitalized patients, which is statistically significant (P=0.001). It shows that, the frequency of vitamin D3 consumption in the outpatient group was higher than inpatient group. This significant difference has also been shown in zinc consumption, in 29 patients (9%) outpatients versus 4 patients (2%) inpatients were reported (P=0.007). Multi nominal regression showed that vitamin D3 intake has a supportive effect and reduces the risk of exacerbation and worsening of the disease. (OR=0.291; 95% CI 0.102-.0834, P=0.022). Conclusion: According to the results of the present study and the findings of other studies, considering the supportive effect of vitamin D3 in reducing the severity of infectious diseases; Clinical trials with an appropriate sample size are recommended to investigate the functional role of this vitamin in improving viral diseases of the respiratory tract

Abstract Background Diabetes mellitus (DM) is associated with poorer outcomes in some cancers. Its effect on ovarian cancer is less clear. We consider the effect of DM on overall survival (OS) and progression free survival (PFS) in patients with epithelial ovarian cancer (EOC). Methods A retrospective cohort study of 215 patients with EOC diagnosed between 2009 and 2016 was performed. Records were reviewed for standard demographic, pathologic and DM diagnosis data. Cox regression was used to evaluate the relationship between disease status and survival after adjustment for age, body mass index (BMI), parity, stage, grade, histology, debulking status, hypertension (HTN), menopause status and neoadjuant chemotherapy. Results Patients with DM (27.97, 95%CI: 23.63 to 32.30) had a significantly shorter OS rates compared to patients without DM (41.01, 95%CI: 38.84 to 43.17). The unadjusted hazard ratio (HR) for the association between OS time and DM was 4.76 (95%CI: 2.99 to 7.59, P

Objective:To evaluate effects ofG-CSF on a cancelled ART cycle due to thin endometrium. Materials and methods:In a nonrandomized clinical trial from January 2011 to January 2013 in two tertiary university based hospitals fifteen patients undergoing embryo transfer and with the history of cycle cancellation due to thin endometrium were studied. Intrauterine infusion of G-CSF was done on the day of oocyte pick-up or 5 days before embryo transfer. The primary outcome to be measured was an endometrium thickened to at least 6 mm and the secondary outcome was clinical pregnancy rate and consequently take-home baby. All previous cycles were considered as control for each patient. Results:The G-CSF was infused at the day of oocyte retrieval or 5 days before embryo transfer. The endometrial thickness reached from3.593±0.251 mm to 7.120±0.84 mm. The mean age, gravidity, parity, and FSH were 35.13± 9.531 years,3, 1 and32.78± 31.10 mIU/ml, respectively. The clinical pregnancy rate was 20%, and there was one missed abortion, a mother death at 34 weeks, and a preterm labor at 30 weeks due to PROM. Conclusion:G-CSF may increase endometrial thickness in the small group of patients who had no choice except cycle cancellation or surrogacy.

Objective: To determine the effect of paternal age on preterm births in Iranian neonates. Materials and methods: From January 2005 to January 2006, two hundred eighty one preterm neonates born in Mirza Kuchakkhan Hospital enrolled in this cross-sectional study. A structured questionnaire was applied for recording following data: birth weight, sex, gestational age, maternal age and paternal age. The study was limited to neonates whose maternal age was between 20 and 30 years to eliminate its confounding effect. Results: Near 50% of fathers were between 30-39 years old and more than half of neonates had gestational age between 35-37 weeks. There were no relation between either paternal age (p= 0.1) or birth weight (p=0.5) and neonatal gestational age. In women with parity one, there was not significant difference between gestational age among different paternal age levels ( p= 0.6) as well as women with parity two and three (p=0.2, p=0.3). Conclusion: Paternal age has no effect on gestational age and birth.
