The Feasibility of Practical Training in Minimally Invasive Surgery at Medical School-A Prospective Study on the Pelvitrainer.

Background and Objectives: The acquisition of practical skills at medical school is an important part of the multidimensional education program of future physicians. However, medical schools throughout the world have been slow in incorporating practical skills in their curriculum. Therefore, the aims of the present prospective study were (a) to demonstrate the feasibility of such surgical training, (b) to objectify its benefit in medical education, and (c) to investigate the impact of such training on subsequent career choices. Material and Methods: We introduced a two-day laparoscopy course on the pelvitrainer as part of the curriculum of the gynecological internship of fifth year medical students from 2019 to 2020. The results of the students' training were matched to those of surgeons who completed the same curriculum in a professional postgraduate laparoscopy course from 2017 to 2020 in a comparative study design. Additionally, we performed a questionnaire-based evaluation of the impact of the course on medical education and subsequent career choices directly before and after completing the course. Results: A total of 261 medical students and 206 physicians completed the training program. At baseline, the students performed significantly more poorly than physicians in a median of three of four exercises (p < 0.001). However, this evened out in the final runs, during which students performed more poorly than physicians only in one exercise and even better than physicians in one. The general integration of surgical training in medical school curricula was rated very low (12.4% on the VAS, IQR 3-16%) despite the high demand for such training. In the survey, the course was deemed very beneficial for medical education (median VAS 80.7%, IQR 73-98%), but did not appear to influence the students' subsequent career preferences. Conclusions: The acquisition of practical surgical skills during medical school is significantly under-represented in many medical faculties. The benefits of such training, as demonstrated in our study, would improve the education of future physicians.

How do new mothers describe their postpartum sexual quality of life? a qualitative study.

BACKGROUND: Sexuality plays a critical role in a woman's postpartum quality of life and also has a strong impact on the quality of her relationship. Given the sparse body of published literature on the subject, we aimed to explore how new mothers explain their postpartum sexual quality of life. METHOD: A qualitative study was carried out in Iran and Switzerland from December 2018 to March 2019. Focus groups and semi-structured in-depth interviews (IDIs) were conducted with mothers in the first four months after parturition. Mothers who were older than 18 years, were married or in a stable relationship, and experienced a low-risk vaginal birth or cesarean section participated in the study. We used Graneheim and Lundman's approach for analyzing the data. Multiple data collection methods, maximum variation sampling, and peer checks were applied to enhance the rigor of the data. RESULTS: We achieved data saturation after two focus group discussions (FGDs), 15 IDIs in Iran, and 13 IDIs in Switzerland. We extracted three themes for postpartum sexual quality of life: (a) sexual worldview, (b) interpersonal relationship, and (c) postpartum sex storm. The participants described sexual worldview as "sexual beliefs", "sexual perceptions", and "sexual behaviors". The interpersonal relationship consists of "changes in postpartum interpersonal relationships" and "supportive role of the husbands/partners". The last one, postpartum sex storm, has three categories including "direct changes in sexual life", "indirect changes in sexual life", and "resumption of sexual intercourse". Differences between the two cultures were identified in some subcategories such as "sexual interests", "comparable to the first intercourse in life", "negative sexual behaviors of husbands/partners", "positive sexual behavior of mothers", "helping with child care and housework", and "emotional support". CONCLUSION: New mothers explained postpartum sexual quality of life as a three-theme phenomenon. Although most results were similar in both cultures, there were some differences. Our study's results suggest that sexual quality of life is a topic that encompasses international as well as cultural aspects.

Diagnostic and Management Performance of ChatGPT in Obstetrics and Gynecology.

OBJECTIVES: The use of artificial intelligence (AI) in clinical patient management and medical education has been advancing over time. ChatGPT was developed and trained recently, using a large quantity of textual data from the internet. Medical science is expected to be transformed by its use. The present study was conducted to evaluate the diagnostic and management performance of the ChatGPT AI model in obstetrics and gynecology. DESIGN: A cross-sectional study was conducted. PARTICIPANTS/MATERIALS, SETTING, METHODS: This study was conducted in Iran in March 2023. Medical histories and examination results of 30 cases were determined in six areas of obstetrics and gynecology. The cases were presented to a gynecologist and ChatGPT for diagnosis and management. Answers from the gynecologist and ChatGPT were compared, and the diagnostic and management performance of ChatGPT were determined. RESULTS: Ninety percent (27 of 30) of the cases in obstetrics and gynecology were correctly handled by ChatGPT. Its responses were eloquent, informed, and free of a significant number of errors or misinformation. Even when the answers provided by ChatGPT were incorrect, the responses contained a logical explanation about the case as well as information provided in the question stem. LIMITATIONS: The data used in this study were taken from the electronic book and may reflect bias in the diagnosis of ChatGPT. CONCLUSIONS: This is the first evaluation of ChatGPT's performance in diagnosis and management in the field of obstetrics and gynecology. It appears that ChatGPT has potential applications in the practice of medicine and is (currently) free and simple to use. However, several ethical considerations and limitations such as bias, validity, copyright infringement, and plagiarism need to be addressed in future studies.

Hysterectomy Using Vaginal Natural Orifice Transluminal Endoscopic Surgery Compared with Classic Laparoscopic Hysterectomy: A New Advantageous Approach? A Systematic Review on Surgical Outcomes.

INTRODUCTION: Minimally invasive surgery aims to reduce surgical trauma and post-operative morbidity. Natural orifice transluminal endoscopic surgery is a safe and valid surgical option for hysterectomy. The present systematic review aims to compare hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) with laparoscopic hysterectomy in terms of efficacy, surgical outcomes, complications, and cost. MATERIALS AND METHODS: This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. It includes randomized controlled trials, controlled clinical trials, prospective or retrospective cohorts, case-control studies, and previous systematic reviews. Inclusion criteria are as follows: female patients undergoing hysterectomy for benign pathologies by vNOTES or laparoscopic hysterectomy. The assessed outcomes were the following: conversion rate, mean uterus weight (g), operative time (mins), hospital stay (days), peri-operative complications, post-operative complications, peri-operative blood loss (mL), blood transfusion needs, post-operative day 1 hemoglobin (Hb) change (g/dL), post-operative pain level (VAS), and cost (USD) in both techniques. RESULTS: Seven studies were included. vNOTES hysterectomy was not inferior to laparoscopic hysterectomy regarding surgical outcomes, with a shorter operative time, shorter recovery time, less post-operative pain, and fewer post-operative complications. There was no significant difference in the rate of peri-operative complications and no differences in peri-operative blood loss, post-operative day 1 Hb change, and transfusions. Nevertheless, vNOTES hysterectomy was shown to be more expensive than its laparoscopic counterpart. CONCLUSIONS: While the feasibility and safety of the vNOTES hysterectomy were already established, this review also underlines the noninferiority of this technique when compared to laparoscopic hysterectomy in terms of surgical outcomes. In addition, vNOTES hysterectomy was associated with faster operating time, shorter hospital stay, and better post-operative pain scores compared with laparoscopic hysterectomy.

Mapping of Iranian midwifery curriculum according to the International Confederation of midwives competencies.

BACKGROUND: Evaluating the curriculum based on its success rate in preparing skilled midwives proficient in performing professional skills is a fundamental component of the midwifery education system. This study aimed to evaluate the content, strengths, and weaknesses of the midwifery curriculum in Iran based on the most recent ICM midwifery education standards in all competence areas, as well as to obtain expert feedback on the necessary courses or lessons for the curriculum using the Delphi method. METHODS: This research was conducted in two phases: comparative analysis and the Delphi method. In the comparative analysis, the curriculum mapping tool was used to compare Iran's midwifery curriculum for bachelor's degrees to the international standards for midwifery education proposed by ICM in 2019 by a four-point Likert scale (adequate- relatively adequate- relatively inadequate- inadequate). Two individuals evaluated the curriculum independently for the presence of theoretical and clinical courses for attaining each relevant competency. In case of disagreement, the opinion of a third person was used. After identifying the academic deficiencies and weaknesses of the curriculum, the Delphi technique was used with the cooperation of the midwifery board members and directors of midwifery groups from across the country to collect feedback about new courses or lessons that need to be incorporated into the curriculum. RESULTS: After a comparative analysis, 24 out of 315 essential competencies for ICM in the midwifery curriculum were found to be inadequate or relatively inadequate based on the three experts' opinions after reviewing the programmatic courses and lessons in the curriculum. In 79.5% of the knowledge area and 71.6% of the skill area, the curriculum for midwifery in Iran corresponded to ICM essential competencies. After surveying expert members during multiple Delphi rounds, the members agreed to add some lessons to the midwifery curriculum, design a new course, and hold related workshops to cover the competencies identified as inadequate or relatively inadequate in the comparative analysis. CONCLUSION: The Iranian midwifery curriculum for acquiring 24 items of ICM essential competencies was deemed inadequate or relatively inadequate. Therefore, it seems in addition to revising Iran's midwifery curriculum following ICM competencies, providing midwifery policymakers with infrastructure and additional support to develop and implement effective midwifery training programs is necessary to ensure that midwives are trained and equipped with the necessary competencies for practice.

Molecular Determinants of Uterine Receptivity: Comparison of Successful Implantation, Recurrent Miscarriage, and Recurrent Implantation Failure.

Embryo implantation is one of the most remarkable phenomena in human reproduction and is not yet fully understood. Proper endometrial function as well as a dynamic interaction between the endometrium itself and the blastocyst-the so-called embryo-maternal dialog-are necessary for successful implantation. Several physiological and molecular processes are involved in the success of implantation. This review describes estrogen, progesterone and their receptors, as well as the role of the cytokines interleukin (IL)-6, IL-8, leukemia inhibitory factor (LIF), IL-11, IL-1, and the glycoprotein glycodelin in successful implantation, in cases of recurrent implantation failure (RIF) and in cases of recurrent pregnancy loss (RPL). Are there differences at the molecular level underlying RIF or RPL? Since implantation has already taken place in the case of RPL, it is conceivable that different molecular biological baseline situations underlie the respective problems.

A targeted educational programme improves fundamental knowledge of menstrual pain and endometriosis in young women: The Endometriosis Awareness Promotion Project.

RESEARCH QUESTION: Would a properly designed educational programme offered to young women improve their awareness and fundamental knowledge of menstrual pain and endometriosis? DESIGN: A multinational cross-sectional study using a pen-and-paper questionnaire among women aged 19-24 years was conducted between 2017 and 2019 to assess fundamental knowledge of menstrual pain and endometriosis. Improvement in knowledge was also analysed using a separate questionnaire completed before, and 1-3 months after, a group discussion, lecture on menstrual pain and endometriosis, or both. RESULTS: Among three groups of students (college [n = 271], medical [n = 877] and nursing [n = 763]), knowledge of menstrual pain and endometriosis was lowest among college students, modest among nursing students and fair among medical students (P < 0.001 for each). The experience of cyclical pain, even when painkillers were taken, was reported by 15.5%, 4.6% and 3.8% of students, respectively. Most students managed their cyclical pain by enduring it or by taking over-the-counter medication. An informative education programme with group discussions, lectures, or both, was successful in improving knowledge and consequences of menstrual pain and endometriosis. Proper education and dissemination of knowledge to college students failed to motivate them to visit gynaecologists; however, medical and nursing students became highly interested in visiting gynaecologists. CONCLUSIONS: An educational programme can improve awareness and knowledge of endometriosis and dysmenorrhoea among young women. The programme motivated nursing and medical students, but not college students, to seek medical attention for early detection and management of endometriosis.

Sexual Function and Mood Disorders Among Menopausal Women: A Systematic Scoping Review.

BACKGROUND: Changes in sex hormones during menopause may have detrimental effects on a woman's sexual function and cause mood disorders. The treatment of both conditions is a challenge in gynecology. AIM: To review the published literature on sexual function and mood disorders among peri- and postmenopausal women. METHODS: The review is based on the methodological framework of scoping reviews. We searched electronic databases including Medline (PubMed), Scopus, Embase, and Web of Science (WoS). Publications that reported data about the relationship between sexual function and mood disorders among menopausal women were included in the review. The search was not subject to any limitation in terms of time or method. OUTCOMES: The main outcome measures used for the review were sexual dysfunction and mood disorders. RESULTS: We found 106 total records. After a full-text screening we included 19 studies from 1986 to 2020 based on various methodologies; the majority of the studies16 were cross-sectional. Investigations that addressed the symptoms of mood disorders and some domains of sexual function showed a close relationship between sexual dysfunction and mood disorders among menopausal women. CLINICAL IMPLICATIONS: In clinical practice, it would be appropriate to screen women for at least one mood disorder or sexual dysfunction. If a woman suffers from either, it will be necessary to assess for a further disorder as well. STRENGTHS & LIMITATIONS: The review was based on a detailed search of the published literature concerning mood disorders and sexual dysfunction among menopausal women compared to women of reproductive age. Despite the clinical importance of the subject, the number of studies eligible for inclusion in the review are rather small. Further investigation of the topic is clearly warranted. CONCLUSIONS: While the association between sexual dysfunction and mood disorders appears to be bidirectional, future studies will have to investigate the specific mechanisms by which sexual dysfunction could lead to mood disorders (or vice versa). Future studies should specifically address sexual dysfunctions and attitudes of partners, BMI, family support, sleep, and multiparity.

Severe direct and indirect complications of morcellation after hysterectomy or myomectomy.

INTRODUCTION: Despite the significant advantages of morcellation, it may be associated with severe complications. We aimed to determine both direct and indirect complication rates of morcellation at gynecological laparoscopy. MATERIAL AND METHODS: This multicenter retrospective study included patients traced from 2008 to 2017. We identified women who underwent an operation with the use of electromechanical power morcellation (EMM) or vaginal manual morcellation during laparoscopy. Clinical records, intraoperative-postoperative outcomes were reviewed. RESULTS: We analyzed 1795 patients who underwent laparoscopic supracervical hysterectomy (LASH), total hysterectomy (TLH), or myomectomy (45.5%, 14.2%, and 40.3%, respectively). No severe intraoperative complications associated with morcellation or parasitic leiomyoma were observed. Patients with unexpected sarcoma were detected in five cases (0.28%). Four of them were detected after LASH and one after vaginal manual morcellation following TLH, who had an intraabdominal recurrence and died after 18 months. The patients after LASH underwent secondary laparotomy for staging; no histological dissemination of sarcoma was observed, however two had a recurrence. The five-year survival rate was 80%. CONCLUSIONS: There is a small risk of intraoperative complications or unexpected malignancy following morcellation, provided the surgeon adheres to regular surgical standards. In patients with a normal size uterus, TLH could be preferred over LASH to avoid morcellation.

Lymphadenectomy in endometrial cancer - achieving more with less?

The lymph node status of patients with endometrial cancer is known to be a crucial determinant for the prognosis of the disease. It also provides the indication for further adjuvant treatment. The staging of endometrial cancer by surgery has been a controversial issue for more than 30 years. The significant complication rate after lymphadenectomy and the development of minimally invasive surgery have led to the use of sentinel lymph node (SLN) mapping. In the present review, we present the development of surgical staging procedures in patients with endometrial cancer and summarize the recently expanding body of published literature on the subject. SLN mapping is a safe and accurate technique, especially when indocyanine green is used as a tracer. SLN mapping appears to reduce complication rates as well as costs without affecting the oncologic outcome. Large prospective studies are needed to establish the effects of SLN mapping on the outcome of disease, especially in high-risk patients with endometrial cancer. Furthermore, the need for additional systematic lymphadenectomy prior to adjuvant radio-chemotherapy in patients diagnosed with isolated lymph node metastasis during SLN biopsy must be investigated further. This might pave the way for a new surgical approach in patients with endometrial cancer.

Correlation between Alkaline Phosphatase and Neonatal Jaundice.

Background: Hyperbilirubinemia is one of the most common neonatal disorders and one of the risk factors of neurological complications. So this study was conducted to evaluate the correlation between alkaline phosphatase (ALP) and pathological jaundice. Methods: A case-control was performed on term neonates with and without pathological jaundice who were referred to the Hazrat-e-Ali Asghar Hospital in 2017. In both groups, cases (neonates with pathological jaundice, n=153) and control (neonates with and without pathological jaundice, n=153) levels of alkaline-phosphatase and serum total bilirubin were evaluated with biochemical tests. Moreover, other data were also recorded from their history and clinical examinations. In addition, the severity of jaundice, duration of hospitalization, type of required treatment, and probable complications after the treatment were considered in follow-up. Data were collected by checklist and entered to SPSS v.20. ALP level and its relationship with serum total bilirubin compared between two groups. Results: Mean level of ALP was 411.3 ± 134.2 U/L in the case group and 338 ± 131.4 U/L in the control group. Serum total bilirubin level was 11.9 mg/dl in the case group and 6.2 mg/dl in the control group. ALP levels in the case group were significantly more than the control group (p=0.001). There was no correlation between ALP and serum total bilirubin level in neonates in the case group (p=0.532). There was no statistically significant relationship between alkaline phosphatase level and gender of neonates, but the relationship of ALP level with types of delivery was statistically significant (p=0.002). There was not a significant relationship between ALP level with hospitalization duration (p=0.371). Conclusion: The result of this study showed that there is no correlation between ALP levels and pathological jaundice in patients, although this issue needs to be approved by the other studies.

Proposing a machine-learning based method to predict stillbirth before and during delivery and ranking the features: nationwide retrospective cross-sectional study.

BACKGROUND: Stillbirth is defined as fetal loss in pregnancy beyond 28 weeks by WHO. In this study, a machine-learning based method is proposed to predict stillbirth from livebirth and discriminate stillbirth before and during delivery and rank the features. METHOD: A two-step stack ensemble classifier is proposed for classifying the instances into stillbirth and livebirth at the first step and then, classifying stillbirth before delivery from stillbirth during the labor at the second step. The proposed SE has two consecutive layers including the same classifiers. The base classifiers in each layer are decision tree, Gradient boosting classifier, logistics regression, random forest and support vector machines which are trained independently and aggregated based on Vote boosting method. Moreover, a new feature ranking method is proposed in this study based on mean decrease accuracy, Gini Index and model coefficients to find high-ranked features. RESULTS: IMAN registry dataset is used in this study considering all births at or beyond 28th gestational week from 2016/04/01 to 2017/01/01 including 1,415,623 live birth and 5502 stillbirth cases. A combination of maternal demographic features, clinical history, fetal properties, delivery descriptors, environmental features, healthcare service provider descriptors and socio-demographic features are considered. The experimental results show that our proposed SE outperforms the compared classifiers with the average accuracy of 90%, sensitivity of 91%, specificity of 88%. The discrimination of the proposed SE is assessed and the average AUC of ±95%, CI of 90.51% ±1.08 and 90% ±1.12 is obtained on training dataset for model development and test dataset for external validation, respectively. The proposed SE is calibrated using isotopic nonparametric calibration method with the score of 0.07. The process is repeated 10,000 times and AUC of SE classifiers using random different training datasets as null distribution. The obtained p-value to assess the specificity of the proposed SE is 0.0126 which shows the significance of the proposed SE. CONCLUSIONS: Gestational age and fetal height are two most important features for discriminating livebirth from stillbirth. Moreover, hospital, province, delivery main cause, perinatal abnormality, miscarriage number and maternal age are the most important features for classifying stillbirth before and during delivery.

Changes in pregnancy outcomes during the COVID-19 lockdown in Iran.

BACKGROUND: The Covid-19 pandemic response is influencing maternal and neonatal health care services especially in developing countries. However, the indirect effects of Covid-19 on pregnancy outcomes remain unknown. The aim of the present study was to compare pregnancy outcomes before and after the beginning of the Covid-19 pandemic in Iran. METHODS: We performed a retrospective analysis of the medical records of 2,503 pregnant women with singleton pregnancies, admitted to the maternity department of a women's hospital in Tehran, Iran, during the pre-Covid-19 pandemic (February 19 to April 19, 2019) and the intra-Covid- 19 pandemic (February 19 to April 19, 2020) period. RESULTS: We included 2,503 women admitted to the hospital; 1,287 (51.4 %) were admitted before the Covid-19 lockdown and 1,216 (48.6 %) during the Covid-19 lockdown. There were no significant differences in stillbirth rates (p = 0.584) or pregnancy complications (including preeclampsia, pregnancy-induced hypertension and gestational diabetes) (p = 0.115) between pregnant women in the pre- and intra-pandemic periods. However, decreases in preterm births (p = 0.001), and low birth weight (p = 0.005) were observed in the pandemic period compared to the pre-pandemic period. No significant difference in the mode of delivery, and no maternal deaths were observed during the two time periods. CONCLUSIONS: In our study we observed a decrease in preterm births and low birth weight, no change in stillbirths, and a rise in the admission rates of mothers to the ICU during the initial Covid-19 lockdown period compared to pre-Covid-19 lockdown period. Further research will be needed to devise plan for immediate post-pandemic care and future health care crises.

Babu and Magon uterine closure technique during cesarean section: A randomized double-blind trial.

AIM: We compared the effectiveness of the Babu and Magon uterine closure technique and unlocked double-layer uterine closure on the integrity and thickness of the uterine scar. METHODS: A randomized double-blind trial was performed at Hazrat-e Rasoul -e-Akram Hospital, Tehran, Iran, from March 2018 to December 2019, in 72 pregnant women who were candidates for cesarean section for the first time. Women were randomly assigned to the Babu and Magon uterine closure technique (intervention group, n = 34) or double-layer closure of the uterine incision (control group, n = 38). The primary outcome of the study was the frequency of myometrial defects at the site of the scar (niche), and a large niche. Secondary outcomes, including the time taken for uterine closure and postpartum hemorrhage (early and late), were compared between groups. RESULTS: Adjacent myometrium thickness (AMT) between the two groups was not statistically significant. A niche was reported in 23.5% (8/34) and 50% (19/38) of women in the intervention and controls, respectively (p = 0.02). A large niche was reported in 2.9% (1/34) and 23.7% (9/38) of women in the intervention and controls, respectively (p < 0.01). The duration of uterine closure was not statistically significant between the two groups. Hemoglobin levels did not differ significantly between groups during the first 24 h post-surgery. CONCLUSION: The results of the study showed that the technique of uterine closure is one of the main potential determinants of myometrial healing. The Babu and Magon uterine closure technique seems to lead to tissue alignment during suturing and consequently cause better myometrial healing, although this issue calls for well-founded longer studies of appropriate design.

Can the prophylactic quadrivalent HPV vaccine be used as a therapeutic agent in women with CIN? A randomized trial.

BACKGROUND: Human papillomavirus (HPV) is one of the most significant risk factors for cervical cancer. The HPV vaccine has a very significant impact on the incidence of cervical cancer. The present study aimed to investigate the impact of prophylactic quadrivalent HPV vaccine in the treatment of women with cervical intraepithelial neoplasia (CIN 1-3). METHODS: This randomized controlled trial was conducted in the Shahid Sadoughi University of Medical Sciences (SSUMS), Yazd, Iran, from October 2011 to November 2015 in women with histologically confirmed residual/recurrent CIN 1 or high-grade CIN (CIN 2-3). Eligible women were assigned randomly to an intervention and a control group. Women in the intervention group were given HPV vaccinations while those in the control group were not. Participants were followed up for 24 months. Primary and secondary outcomes, and adverse effects of the treatment in the two groups were compared using Student's t test, the chi-square test, or Fisher's exact test. P values < 0.05 or less were considered statistically significant. RESULTS: Three-hundred and twelve women were randomized to the two groups; the data of 138 in the intervention group and 104 in the control group were analyzed. The mean age of the women was 32.59 ± 4.85 years. Differences in age, marital status, and grades of CIN weren't significant between the two groups. At the end of the two-year follow-up period, the number of women with CIN 2-3 in the intervention and control groups was reduced by 75% (from 93 to 23) versus 40% (from 69 to 41). The efficacy of the HPV vaccine in women with CIN 1-3 was 58.7% (p = 0.018). No serious adverse effects related to the vaccines were reported. CONCLUSIONS: The prophylactic quadrivalent HPV vaccine after treatment may have a therapeutic effect in women with residual/recurrent CIN 1 or high-grade CIN (CIN 2-3).

Uterine Isthmus Tourniquet during Abdominal Myomectomy: Support or Hazard? A Randomized Double-Blind Trial.

BACKGROUND AND OBJECTIVES: A tourniquet has been suggested as a useful means of reducing massive hemorrhage during myomectomy. However, it is not clear whether the restricted perfusion affects the ovaries. In the present study, we examined the effect of a tourniquet on ovarian reserve and blood loss during myomectomy. MATERIALS AND METHODS: In a randomized double-blind clinical trial, fertile nonobese patients scheduled for abdominal myomectomy at Rasool-e-Akram Hospital from February 2018 to June 2019 were randomized to a tourniquet (n = 46) or a non-tourniquet group (n = 35). Serum levels of anti-Müllerian hormone (AMH) and follicle-stimulating hormone (FSH) were measured before and 3 months after surgery, blood loss was recorded during surgery, and serum levels of hemoglobin (Hb) were recorded before surgery, 6 h and 3 days after surgery. SPSS version 21 was used for statistical analysis. RESULTS: Demographic, obstetric, and myoma characteristics were similar in the 2 groups (p > 0.05). The mean baseline values of AMH and FSH did not differ between groups (p > 0.05). After surgery, only FSH was higher in the control group (p = 0.043). Despite the time taken to fasten and open the tourniquet, the mean operating time was shorter in the tourniquet group (p < 0.001). Blood loss was higher in the control group (p = 0.005). The drop in Hb levels at 6 h after surgery was higher in the non-tourniquet group (p = 0.002). Blood loss was significantly associated with the duration of surgery (r = 0.523, p < 0.001). CONCLUSION: The use of a tourniquet during abdominal myomectomy significantly reduced the mean volume of blood loss compared to the non-tourniquet group, while it did not prolong the duration of surgery, nor reduced the ovarian reserve. A tourniquet is a safe and efficient measure during abdominal myomectomy.

Factors affecting dental cleaning behaviour among pregnant women with gingivitis.

OBJECTIVE: Despite the importance of oral health during pregnancy and its consequences for mother and child, dental cleaning behaviour is ineffective among pregnant women; therefore, the prevalence of gingivitis is high in this group. The aim of this study was to determine the factors affecting dental cleaning behaviour among pregnant women with gingivitis. METHODS: This cross-sectional study was carried out in Sanandaj city, in the west of Iran in 2017. Using simple random sampling, 340 pregnant women from five health comprehensive service centres were recruited in the study. Data were gathered by a two-section questionnaire. The first section included demographic information, and the second section involved variables of trans-theoretical model, fear of dental care and social support. Analysis of data was done by SPSS software by frequency, descriptive, Student t-test, ANOVA, chi-square, correlation coefficient and regression. RESULTS: About 50% of the pregnant women were in the first stages of dental cleaning behaviour change. The mean score of gingival index (P = 0.01), perceived barriers (P < 0.001) and fear of dental care (P = 0.04) was higher in the initial stages of behaviour change (P < 0.001). Perceived self-efficacy was directly correlated with social support and perceived benefits (P < 0.01). Dental cleaning behaviour increased 1.59 times and 1.42 times when perceived self-efficacy and social support were increased one unit, respectively. CONCLUSIONS: The results showed the majority of pregnant women had a low perception of the benefits of dental cleaning behaviour, did not have adequate incentive for doing the behaviour and did not receive the required social support.

Development and psychometric assessment of the sexual health education necessity scale: An exploratory mixed method study.

Background: Sexual health education is a controversial issue within the Iranian context. Thus, the present study was conducted to explore the necessity of sex education among young single women and develop and examine the psychometric properties of the Sexual Health Education Necessity Scale. Methods: This was an exploratory mixed method study. Young single women (51 women in the first phase and 110 women in the second phase of the study) aged 18-34 years were recruited in the study. In the first phase, qualitative methods were applied to generate items. In the second phase, psychometric properties, such as face, content, and construct validity, and reliability of the Sexual Health Education Necessity Scale were evaluated. In the first phase, an item pool was developed that included 17 statements related to sexual health education necessity. In the second phase, item reduction was applied using exploratory factor analysis and the final version of the questionnaire containing 9 items was developed. Also, content, face, and construct validity were assessed. Moreover, Cronbach's alpha coefficient and test-retest were calculated to evaluate the reliability of the questionnaire. SPSS software (version 21) was used for data analysis and p value less than 0.05 was considered as significant. Results: In the qualitative phase, 4 key themes emerged regarding sex education, which included the effects of sex education, principles of sex education, content of sex education, and organizations responsible for sex education. An item pool containing 17 statements was generated and used for psychometric evaluation. The results of the exploratory factor analysis showed a 2-factor solution for the scale, which collectively accounted for the 56.04% of the variance. Final CVR and CVI were found to be 0.96 and 0.97, respectively. The Cronbach's alpha coefficient and test-retest of the instrument was found to be 0.78 and 0.80, respectively. Conclusion: Sexual Health Education Necessity Scale can be used for exploring dominant beliefs that may be obstacles for providing sex education in conservative societies; therefore, correcting these beliefs could help to design an appropriate sexual health education program.

The global incidence, mortality, and burden of uterine cancer in 2019 and correlation with SDI, tobacco, dietary risks, and metabolic risk factors: An ecological study.

Background and Aim: Endometrial cancer (EC) is the sixth most common cancer among women worldwide. Since global studies are based on awareness of the incidence trend, mortality, geographical diversity, and level of social development and income of countries, this study was conducted to investigate the trend of uterine cancer (UC) in the world in 2019. Methods: Age-standardized rates (ASR) of incidence, deaths, prevalence, and disability-adjusted life years (DALYs) of UC, as well as targeted risk factors, were extracted from the Global Burden of Disease (GBD) online database 2019. Pearson correlation coefficient and SPSS 16 were used to calculate the correlation between risk factors and ASR of epidemiological indicators. Statistical significance was considered as p < 0.05. Results: In 2019, the age-specific incidence and death rate of UC was peaking at 60-64 and 65-69 years, respectively. The highest age-standardized incidence rate per 100,000 people for UC has been reported in the Northern Mariana Islands, high sociodemographic index (SDI) countries, World Bank High-Income category, Europe continent and among World Health Organization (WHO) regions were found in the European Region. The highest age-standardized death rate per 100,000 people for UC has been reported in Grenada, high SDI countries, the World Bank High-Income category, Europe continent, and among WHO regions found in the European Region. In 2019, the age-standardized DALYs rate was 53.54 per 100,000 inhabitants, of which 48.49 cases were related to years of life lost (YLLs) and 5.05 cases were related to years lived with disability. Conclusion: According to GBD-2019, the highest incidence, mortality, and DALY of UC are in Europe. The evidence and traces of diversity can be seen in the inequalities of UC. Race, ethnicity, economic status, level of education and awareness, co-morbidities, access, grade, and histological type of tumor are the most important causes of this inequality.
