Introduction: Free radicals play a double role in the body based on their physiological level and can be beneficial or harmful. This review study was performed with aim to evaluate the cellular and molecular mechanisms of oxidative stress on spermatogenesis and oogenesis and the role of using antioxidant in improving fertility in men and women. Methods: In this review study, the issues related to the role of free radicals and antioxidants on male and female fertility disorders were searched in the Persian and English databases including: Elsevier, Scopus, Irandoc, SID, Iran medex, Sciencedirect, Pubmed, GoogleScholar and Web of Science using the keywords of free radicals, male infertility, female infertility, and antioxidants without any time limitation. Finally, 63 studies entered the review study. Results: The excessive production of free radicals in the male reproductive system causes damage to DNA, RNA, and sperm membranes, and ultimately disrupts spermatogenesis. It also causes disorders in the female genital tract including defect in oocyte development and maturation, follicular growth and function of corpus luteum. Conclusion: According the results of previous studies, using antioxidants may remove the harmful effects of free radicals on male and female fertility.
导读:自由基在人体中根据其生理水平起着双重作用,可有益也可有害。本文旨在探讨氧化应激对精子和卵子发生的细胞和分子机制,以及抗氧化剂在提高男性和女性生育能力中的作用。方法:在本综述研究中,以自由基、男性不育、女性不育、抗氧化剂为关键词,无时间限制地检索Elsevier、Scopus、Irandoc、SID、Iran medex、Sciencedirect、Pubmed、GoogleScholar和Web of Science等波斯语和英语数据库中有关自由基和抗氧化剂在男性和女性生育障碍中的作用的相关问题。最终有63项研究进入回顾性研究。结果:男性生殖系统中自由基的过量产生会导致DNA、RNA和精子膜的损伤,最终破坏精子的发生。它还会引起女性生殖道的紊乱,包括卵母细胞发育和成熟、卵泡生长和黄体功能的缺陷。结论:根据以往的研究结果,使用抗氧化剂可以消除自由基对男性和女性生育能力的有害影响。

ntroduction: Chronic inflammation can be the main cause of many common diseases in old age. Elevated level of CRP and proinflammatory cytokines such as TNF-α is positively associated with fibroblast growth factor 23 (FGF23). Therefore, considering the potentially beneficial effect of elastic band resistance training (EBRT) on these variables, this study was performed with aim to investigate the effect of 12 weeks of selected EBRT on serum levels of FGF23, TNF-α and hsCRP in overweight elderly women. Methods: This clinical trial study was performed in 2017 on 28 elderly women in Shahrekord.  The subjects were randomly divided into experimental and control groups. EBRT was performed for 12 weeks. Fasting blood samples were taken 24 hours before the first training session and 48 hours after the last training session to measure serum levels of FGF23, TNF-α and hsCRP. Data were analyzed by SPSS software (version 25) and repeated measure two-way ANOVA test. P<0.05 was considered statistically significant. Results: EBRT had no significant effect on serum FGF23 levels, BMI, and Waist-to-hip ratio in elderly women (P>0.05); but serum levels of TNF-α (P=0.046), hsCRP (P=0.037), and also body fat percentage (P=0.023) significantly decreased after EBRT. Conclusion: Regardless to no significant changes in FGF23 levels, it seems that 12 weeks of EBRT can have a significant effect on reducing chronic inflammation in the elderly by reducing the levels of hsCRP and proinflammatory cytokine TNF-α.
导读:慢性炎症可能是老年许多常见疾病的主要原因。CRP和促炎细胞因子如TNF-α水平升高与成纤维细胞生长因子23 (FGF23)呈正相关。因此,考虑到弹性带阻力训练(EBRT)对这些变量的潜在有益影响,本研究旨在研究选择EBRT 12周对超重老年妇女血清FGF23、TNF-α和hsCRP水平的影响。方法:本临床试验研究于2017年在Shahrekord的28名老年妇女中进行。受试者随机分为实验组和对照组。EBRT治疗12周。在第一次训练前24小时和最后一次训练后48小时采集空腹血样,测量血清中FGF23、TNF-α和hsCRP的水平。数据分析采用SPSS软件(25版)和重复测量双因素方差分析。P0.05);血清TNF-α (P=0.046)、hsCRP (P=0.037)和体脂率(P=0.023)均显著降低。结论:尽管FGF23水平没有明显变化,但12周EBRT似乎可以通过降低hsCRP和促炎细胞因子TNF-α水平,对老年人的慢性炎症有显著的减轻作用。

Introduction: Cesarean section is performed with two technique of closure or non-closure of the peritoneum, but there is disagreement about the advantages and disadvantages of these techniques. Accordingly, this study was performed with aim to compare the early maternal complications of cesarean section in two technique of closure or non-closure of the parietal peritoneum. Methods: This double-blind randomized clinical trial study was performed on 120 patients undergoing cesarean section at Hamadan Fatimah Hospital in 2019. Samples were randomly divided into two groups: closure of the peritoneum (n=60) and non-closure of the peritoneum (n=60). The maternal complications during and after surgery were recorded. Data were analyzed by SPSS software (version 21) and Chi-square, independent t-test and repeated measures. Results: The results showed that operative time and bleeding during surgery were significantly fewer in patients receiving non-closure technique (p 0.05). Conclusion: The complications such as bleeding during surgery, the duration of surgery, ileus after surgery, pain, and consumption of analgesic will occurs with less intensity in patients receiving non-closure technique than patients with closure technique; however, these two methods were not different in terms of surgical wound infection.

Introduction: Given the importance of assisted reproductive therapies and achieving a pregnancy leading to live birth, as well as the importance of the used treatments and the various studies which have been performed so far, this study was performed with aim to evaluate the relationship between endometrial pattern and serum progesterone levels at the day before the onset of progesterone suppository in embryo transfer cycles in women referred to Infertility Center of Zahedan. Methods: This cross-sectional study was performed on 50 women who had undergone IVF for any reason and their embryos were frozen in infertility center of Zahedan University of Medical Sciences in 2019. The patients were treated with progesterone suppository 400 mg at morning and 400 mg at evening intra rectally. Demographic data, endometrial pattern and thickness ultrasound, serum progesterone level at the day before the onset of progesterone suppository and serum BHCG levels 14 days after embryo transfer were recorded. Data were analyzed by SPSS statistical software (version 24) and Chi-square and Mann-Whitney tests. P<0.05 was considered statistically significant. Results: IVF outcome was positive in 13 cases (26%). 23 patients (46%) had homogenous endometrial pattern and 27 (54%) had three-line pattern. Serum progesterone level were significantly lower in patients who had positive BHCG than patients who had negative BHCG (p <0.001). Conclusion: Among women undergoing IVF, serum progesterone levels and also endometrial pattern (homogenous or three-line) was different. Serum progesterone level before the onset of treatment was related to the pregnancy outcome (positive or negative), as well as in women with lower progesterone levels   in day before the start of progesterone suppositories, treatment with progesterone suppository could lead to better pregnancy outcomes following IVF, which is a novel and important finding.
摘要:考虑到辅助生殖治疗和实现妊娠并活产的重要性,以及所使用的治疗方法的重要性和迄今为止所进行的各种研究,本研究旨在评估在扎黑丹不孕不育中心转介的妇女胚胎移植周期中孕酮栓剂开始前一天的子宫内膜模式与血清孕酮水平的关系。方法:对2019年在扎黑丹医科大学不孕症中心冷冻胚胎的50例因各种原因接受体外受精的女性进行横断面研究。患者均给予孕酮栓剂400 mg,早晚直肠内注射。记录人口统计学资料、子宫内膜形态及超声厚度、孕酮栓剂起药前一天血清孕酮水平及胚胎移植后第14天血清BHCG水平。数据采用SPSS统计软件(version 24)、卡方检验和Mann-Whitney检验进行分析。P<0.05为差异有统计学意义。结果:13例(26%)体外受精结果阳性。同质型子宫内膜23例(46%),三线型27例(54%)。BHCG阳性患者血清孕酮水平明显低于BHCG阴性患者(p <0.001)。结论:在接受体外受精的妇女中,血清黄体酮水平和子宫内膜模式(同质或三线)不同。治疗开始前血清孕酮水平与妊娠结局(阳性或阴性)相关,并且在孕酮栓剂开始前一天孕酮水平较低的妇女中,孕酮栓剂治疗可使体外受精后妊娠结局更好,这是一项新的重要发现。

Uterine prolapse has been traditionally treated with vaginal hysterectomy and cuff suspension . Recently there is renewed interest in uterine conservation during prolapse surgeries. Prolapse repair with uterine sparing has benefits as shorten time surgery, lesser bleeding, preserving fertility, less invasion and faster recovery. The purpose of this study was to evaluate the success rate and quality of life in women who have undergone one of three types of uterine sparing prolapse surgery. Methods and MaterialsThis retrospective study was performed in Imam Khomeini Hospital, Tehran University of Medical Sciences. The data of 99 patients with uterine prolapse who underwent one of three types of uterine sparing surgery during three years were reviewed and compared in success rate and quality of life.ResultsThe study was based on patients' data files, physical examination and follow up, until 12 months after surgery. The success rate of sacral hysteropexy was higher than two other groups (94%).The highest recurrence was in sacrospinous, in the Ba point ( -2.06± 506) and C point (-2.1±1.084) . The quality of life in the Manchester and sacral hysteropexy group was similar and higher than sacrospinous group.(P Value≤0.01).Early complications after sacral hysteropexy were ileus and defecatory disorder. ConclusionThree uterine prolapse surgeries had success rate higher than 60%. All three surgical groups had a good quality of life and satisfaction 12 months after procedure. The highest recurrence was in sacrospinous in Ba and C points. Finding mesh complications following surgery requires long-term follow-up.

Data were analyzed by SPSS software (version 16) and statistical tests of t-test, ANOVA, linear regression and Pearson correlation coefficient. P <0.05 was considered statistically significant. Results: The total anxiety score of pregnant women in relation to Covid-19 disease was 18.71 ±12.48 and the perceived stress score was 24.57±7.00. Linear regression test showed that person's job, problems during pregnancy, delivery history, family members infection with coronavirus and concern about the consequences of the disease for themselves and the infant were the predictive variables of perceived stress score; and the variables of family members infection with coronavirus, concerns about infection of themselves and the infant, concern about receiving prenatal care, and the presence of problems during pregnancy were the predictors of anxiety scores in pregnant women. Conclusion: The level of anxiety and stress of pregnant women was high during the Covid-19 pandemic and women had many concerns about infecting themselves and the infant or referring to receive prenatal care.","PeriodicalId":39154,"journal":{"name":"Iranian Journal of Obstetrics, Gynecology and Infertility","volume":"142 1","pages":"8-18"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77835776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AbstractIntroduction: Tubo-ovarian abscess is a final stages in acute pelvic inflammatory disease which may be accurred after uterine manipulation or after surgery and is very rare. Even with the development of antibiotic covering and medical care, mortalities resulted from tubo-oavariane abscess rapture due to septic shock and peritonitis are about 10%. Therefore, early diagnosis and treatment are very important. In this study, a tubo-oavarine abscess fistula to vaginal is reported. Patient Description: the patient is a 44 years old woman who experienced abdominal hysterectomy surgery six months ago and hospitalized for a week due to peritonitis sings but after discharge, she was repeatedly referring because of infectionLeukorrhea and pain. Finally, because of abdominal pain and secretions from the vaginal, she underwent laparoscopy. Tubo-oavariane abscess with fistula to the vagina was observed and the secretions were suctioned and its viscosity was released. Then, ooforectomy and salpingectomy were carried out. Conclusion: about the treatment-resistance Leukorrhea after hysterectomy, tubo-oavarine abscess and frequent infection through fistula should be taken into consideration and diagnosis laparoscopy can be effective to select a suitable treatment.

Introduction: Human chorionic gonadotropin for the final maturation of eggs in the In-vitro fertilization cycle was associated with the possibility of a negative effect on endometrial acceptance, fetal quality and ovarian hyper stimulation syndrome. Replacing it with a gonadotropin-releasing hormone agonist to trigger final ovulation is expected to reduce these effects. Therefore, this study was performed with aim to evaluate the outcome of triggering in in vitro fertilization with antagonist protocol by gonadotropin-releasing hormone agonist, human chorionic gonadotropin simultaneously with human gonadotropin-releasing hormone agonist and human chorionic gonadotropin.  Methods: In this randomized clinical trial study conducted in 2015 and 2016, women were divided into three random groups after preparing the follicles for triggering and ovum retrieval. One group received 0.2 mg of dipherline, the second group received 10,000 units of human chorionic gonadotropin and the other group received 0.2 mg of dipherline along with 1500 units of human chorionic gonadotropin. The number and quality of eggs and embryos were the outcomes of the study. Data were analyzed by SPSS software (version 17) and Leven tests and one-way analysis of variance. P < 0.05 was considered statistically significant.  Results: The number of retrieved oocytes in the group receiving gonadotropin-releasing agonist was significantly higher than the other groups (p = 0.001). More embryos were produced in the gonadotropin-releasing hormone agonist group compared to the other two groups (p = 0.009). However, the number of high quality embryos produced in the groups was similar. Conclusion: The onset of final oocyte maturation with gonadotropin-releasing hormone agonist significantly increases the number of retrieved oocytes and obtained embryos. However, dual stimulation using low-dose human chorionic gonadotropin (IU1500) and gonadotropin-releasing hormone agonist did not alter quality of embryo compared to the standard dose of human chorionic gonadotropin (IU10000).
人绒毛膜促性腺激素用于体外受精周期中卵子的最终成熟,可能对子宫内膜接受、胎儿质量和卵巢过度刺激综合征产生负面影响。用促性腺激素释放激素激动剂替代它来触发最终排卵,有望减少这些影响。因此,本研究旨在评价促性腺激素释放激素激动剂、人绒毛膜促性腺激素与人促性腺激素释放激素激动剂和人绒毛膜促性腺激素同时使用拮抗剂方案触发体外受精的效果。方法:在2015年和2016年进行的随机临床试验研究中,女性在准备好卵泡触发和取卵后随机分为三组。一组注射0.2毫克的迪弗兰,第二组注射10000单位的人绒毛膜促性腺激素,另一组注射0.2毫克的迪弗兰,同时注射1500单位的人绒毛膜促性腺激素。卵子和胚胎的数量和质量是研究的结果。数据采用SPSS软件(version 17)、Leven检验和单因素方差分析。P < 0.05为差异有统计学意义。结果:促性腺激素释放激动剂组取卵数显著高于其他组(p = 0.001)。与其他两组相比,促性腺激素释放激素激动剂组产生的胚胎更多(p = 0.009)。然而,两组中产生的高质量胚胎数量是相似的。结论:使用促性腺激素释放激素激动剂使卵母细胞最终成熟,可显著增加获得的卵母细胞和胚胎的数量。然而,与标准剂量的人绒毛膜促性腺激素(IU10000)相比,使用低剂量的人绒毛膜促性腺激素(IU1500)和促性腺激素释放激素激动剂的双重刺激没有改变胚胎质量。

مقدمه: فیبرینوژن یکی از مهم‌ترین عوامل التهابی و شاخص پیش‌بینی ‌کننده در بیماری‌های قلبی - عروقی است. مطالعه حاضر با هدف بررسی تأثیر تمرینات هوازی با شدت‌های ثابت و متغیر بر ترکیب بدن و برخی عوامل فیزیولوژیک و انعقادی زنان میانسال دارای اضافه وزن انجام شد. روش‌کار: این مطالعه کاربردی و به‌روش نیمه‌تجربی در سال 1394 بر روی 30 زن در سه گروه 10 نفره تمرین هوازی با شدت ثابت، شدت متغیر و کنترل در شهرستان بجنورد انجام شد. برنامه تمرین هوازی شامل 8 هفته تمرین هوازی، 30 دقیقه فعالیت هوازی با شدت ثابت معادل 60% ضربان قلب و با شدت متغیر شامل 2 دقیقه رکاب زدن با شدت 50% حداکثر ضربان قلب و 1 دقیقه رکاب زدن با شدت 70% حداکثر ضربان قلب بود. سطوح فیبرینوژن، PT، PTT، تعداد پلاکت‌ها و  فاکتور غیرانعقادی در 24 ساعت قبل و 48 ساعت بعد از جلسه تمرین جمع‌آوری شد. تجزیه و تحلیل داده‌ها با استفاده از نرم‌افزار آماری SPSS (نسخه 25) و آزمون‌های تی همبسته، تحلیل آنالیز کواریانس (ANCOVA) و آزمون تعقیبی توکی به‌ترتیب برای تغییرات درون‌گروهی و بین‌گروهی انجام شد. میزان p کمتر از 05/0 معنی‌دار در نظر گرفته شد. یافته‌ها: وزن (شدت ثابت 001/0=p و شدت متغیر 001/0=p)، شاخص توده بدنی (شدت ثابت 001/0=p و شدت متغیر 001/0=p)، فشارخون سیستولی (شدت ثابت 03/0=p و شدت متغیر 001/0=p) و فشارخون دیاستولی (شدت ثابت 001/0=p و شدت متغیر 001/0=p) کاهش معنی‌داری یافت؛ در‌صورتی‌که درصد چربی بدن فقط در گروه تمرین هوازی با شدت ثابت کاهش معنی‌داری یافت (001/=p). زمان پروترومبین (شدت ثابت 004/0=p و شدت متغیر 009/0=p)، زمان نسبی ترومبوپلاستین  (شدت ثابت 005/0=p و شدت متغیر 01/0=p)، فیبرینوژن (شدت ثابت 001/0=p و شدت متغیر 02/0=p) و تعداد پلاکت‌ها (شدت ثابت 02/0=p و شدت متغیر 001/0=p)، کاهش معنی‌داری یافت؛ در‌صورتی‌که فاکتور غیرانعقادی در هر دو گروه تمرین هوازی با شدت ثابت و متغیر افزایش معنی‌داری یافت (شدت ثابت 003/0=p و شدت متغیر 001/0=p). میزان انعطاف‌پذیری (شدت ثابت 003/0=p و شدت متغیر 001/0=p) و حداکثر اکسیژن مصرفی (شدت ثابت 001/0=p و شدت متغیر 001/0=p) در هر دو گروه تمرین هوازی با شدت ثابت و متغیر افزایش معنی‌داری یافت. نتیجه‌گیری: 8 هفته تمرین هوازی با دو شدت ثابت و متغیر از طریق کاهش شاخص‌های ترکیب بدن، فاکتورهای انعقادی و افزایش شاخص‌های آمادگی جسمانی در زنان دارای اضافه وزن می‌تواند احتمالا در بهبود سلامت قلب و عروق و کاهش التهاب مؤثر باشد.
