RESUMO
BACKGROUND: Gender dysphoria, characterized by a misalignment between one's gender identity and assigned sex, propels individuals towards medical interventions like gender reassignment surgery (GRS) to harmonize their bodies with their gender. This process aims to enhance overall quality of life (QoL), functioning, and body image. Recognizing the importance of cultivating a positive body image for transgender individuals navigating societal norms, this narrative highlights the ongoing debate surrounding QoL post-GRS. In response, our study is outlined, aiming to scrutinize QoL and self-image among transgender men post-GRS, offering valuable insights into societal perceptions and psychological well-being in this context. METHOD: This cross-sectional survey focused on transgender men aged 15 to 35 who underwent gender reassignment surgery (GRS) in 2018-2022 in Shiraz, Iran. Participants, after passing psychiatric evaluations, completed World Health Organization Quality of Life (WHOQOL-100) questionnaires pre- and at least one-year post-surgery. The scores of the Brief-WHOQOL questionnaire were evaluated in four domains of physical health, psychological health, social relationships, and environmental health. RESULTS: A total of 60 individual who underwent GRS completed our questionnaire. The average age of the patients was 24.1 ± 3.8 years. Following GRS, the most increase was observed in the psychological factor (by 25.6%). The increase in score was statistically significant in all subgroups (P < 0.001) after operation. Urban living location had a significant association with higher increase in physical health (P < 0.010), psychological health (P = 0.005), and environmental health (P = 0.012) after GRS. In regards to physical health, the low socioeconomic group had a significantly less physical score improvement in QoL compared to the moderate group (P = 0.024) following GRS. In regards to environmental health, the high socioeconomic groups had significantly higher improvement in QoL compared to the low (P = 0.006) and moderate (P < 0.001) group after operation. CONCLUSION: The results demonstrate that GRS brings about improvements across all aspects of QoL. However, this enhancement is less pronounced among patients hailing from low socioeconomic backgrounds and rural areas.
RESUMO
BACKGROUND: The role of bacterial contamination in the development and progression of endometriosis lesions is currently a hot topic for gynecologists. In this study, we decided to compare the endometrial cultures of women affected by endometriosis with those of non-endometriotic women, focusing on specific microbial pathogens. MATERIAL AND METHOD: In this cross-sectional case-control study, 30 women with endometriosis in stages 4 of the disease whose endometriosis was confirmed based on clinical, ultrasound, and histopathological findings, and 30 women without endometriosis who were candidates for surgery due to benign uterine diseases with regular menstrual cycle, underwent endometrial biopsy with Novak Kort in sterile conditions before starting their operation, and the results of their endometrial culture were analyzed and compared. RESULTS: Results of the study indicate that there were no significant differences in terms of age, BMI, smoking, education level, place of residency, use of the intrauterine device, or vaginal douche, and age of menarche between the case and control groups. The only demographic difference observed was in parity, where the control group had a significantly higher parity than the case group (P = 0.001). Out of the 60 cultures, only 15 samples were positive in the endometriosis group, and E. coli was the most prevalent species, with 10 (33.3%) samples testing positive for it. Klebsiella spp. and Enterobacteria spp. were also detected in 3 (10.0%) and 2 (6.7%) samples, respectively. The comparison between the two groups showed that only E. coli had a significant association with the presence of endometriosis (P = 0.001). There was no significant relationship between the location of endometriosis in the pelvic cavity and culture results. It was observed that parity among the E. coli negative group was significantly higher compared to the E. coli positive group (P < 0.001). CONCLUSION: Based on The high occurrence of E. coli in women with endometriosis, along with its potential involvement in the progression and/or recurrence of this condition, the researchers propose that treating women with endometriosis and recurrent IVF failure, as well as those with endometriosis recurrence after surgical treatment, with suitable antibiotics and repeated culture until the culture becomes negative, could be beneficial.

RESUMO
Understanding the clogging of mixtures of soft and rigid particles flowing through hoppers becomes important as soft particle usage increases in consumer products. We investigate this clogging under varying particle size and rigid fraction by quantifying various properties of arches formed in the neck of a quasi-two-dimensional hopper. As more soft particles are added to the mixture, the arch tends to become both narrower and more curved. This effect arises from the fact that soft particles have less ability to sustain a clog than rigid particles. The clogging probability is seen to have a linear correlation with the span (width) of the arch. The angles between the arch particles are shown to have higher values as rigid fraction increases. The arch occasionally shows a partially convex shape at high rigid fractions when rigid particles are sitting next to each other, while soft particles can form angles of less than 180^{∘} only. The relation between the span and aspect ratio (width to height) of the arch is theoretically formulated for three-particle arches and extended to arches of more than three particles, using an asymptotic parameter that represents the width of a flat arch. Finally, it is concluded that clogging probability closely correlates with both the arch span and the variation of other geometric arch properties.
RESUMO
AIM: To report single-center outcomes of laparoscopic management of patients with ureteral endometriosis and perform a meta-analysis in order to select the best approach for these patients. METHODS: The cross-sectional study was conducted during a 6-year period (2015-2021) in the referral endometriosis center on 353 patients with ureteral endometriosis. For the meta-analysis, 10 articles, including 505 patients, were found to be eligible. In our meta-analysis, as well as our study, all endometriosis-related pain symptoms and complications of surgery were evaluated, analyzed, and reported. RESULTS: Of the 326 patients whose ureteral involvement was confirmed in pathology, hydronephrosis and intrinsic ureteral lesions were detected in only 10.76% and 3.1% of the patients. Mean operating time and hospitalization were 3.25 ± 1.83 h and 86 ± 2.58 days, respectively. The most common site of concomitant involvement with endometriosis was uterosacral ligament (92.9%) and rectosigmoid (70.53%). Type II and III of Cliven-Dindo complications were seen in 5.66% and 1.13% of patients, respectively. During a follow-up period, no evidence of bladder or ureteral re-involvement was observed. Similar to our meta-analysis, all endometriosis-related pain decreased significantly following operation (p ≤ 0.001). In our meta-analysis, the rate of ureteral endometriosis recurrence, stenosis/stricture, bladder atonia, urinary tract infection, hematuria, and fistula formation after surgery were: 2.0% (I2 : 50.42%), 15.0% (I2 : 0.00%), 14.0% (I2 : 8.76%), 6.0% (I2 : 0.00%), 7.0% (I2 : 79.28%), and 2.0% (I2 : 0.0%), respectively. CONCLUSION: The laparoscopic resection of the UE could be suggested as a feasible and safe method associated with favorable functional outcomes.

OBJECTIVE: This study investigated the long-term outcomes of laparascopic sigmoid cervicovaginoplasty in patients with congenital cervicovaginal atresia with a functioning uterus. METHODS: In this case series study, seven patients with cervicovaginal atresia with a functioning uterus underwent laparoscopic sigmoid cervicovaginoplasty surgery between 2016 and 2020. Mean follow-up duration was 25.9 months (2-48 months). All of the patients had regular menstrual cycles. The average length of the vagina was 8.9 cm (7.6-10.5 cm). In one patient, proximal stenosis of neovagina was observed 12 months after surgery. RESULTS: The mean age and body mass index of the patients were 18 years (12-27 years) and 19.7 (17.6-22.4), respectively. The average time period between the initiation of disease symptoms and the operation was 52.28 months (2-156 months). There were no postoperative short-term complications. We did not perform hysterectomy in our patients. None of our patients complained of signs of low anterior resection syndrome. Two patients had sexual activities without dyspareunia, postcoital bleeding, or malodorous vaginal discharge. CONCLUSION: Sigmoid cervicovaginoplasty is a safe and effective procedure with satisfactory long-term outcomes. This surgery eliminates the psychological burden of hysterectomy in these patients. Through preserving the uterus, patients may have a chance of possible future pregnancy if abdominal cerclage is performed.

OBJECTIVE: To determine and compare the value of magnetic resonance imaging (MRI) and transvaginal sonography (TVS) in the diagnosis of rectal endometriosis. METHODS: In this cross-sectional study, 555 patients with rectal endometriosis, who had undergone MRI and TVS before laparoscopic operation, were included. The sensitivity, specificity, and accuracy of these two imaging modalities were evaluated and compared based on histopathologic reports and three different kinds of rectal endometriosis surgeries (shaving as a first group and disk and segmental resection methods combined as a second group). RESULTS: Sensitivity, specificity, accuracy, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio of ultrasound in the diagnosis of rectal endometriosis were, respectively, 69.55% (65.4%-73.4%), 91.30% (72%-98.9%), 70.4% (66.4%-74.17%), 11.48% (9.77%-13.43%), 99.46% (98%-99.86%), 8.0 (2.12-30.1), and 0.3 (0.28-0.4). These values were 51.37% (47.1%-55.6%), 79.17% (57.8%-92.9%), 52.53% (48.3%-56.6%), 6.64% (5.39%-8.16%), 98.26% (96.26%-99.2%), 2.47 (1.13-5.4), and 0.6 (0.49-077) for MRI. Even though ultrasound had better accuracy for detection of superficial rectal endometriosis (Group 1) (P < 0.001), the sensitivity, specificity, and accuracy of both imaging modalities in diagnosis of deep rectal lesions (Group 2) were almost identical. CONCLUSION: TVS should be considered as a first-line modality for diagnosis of rectal endometriosis, mainly because of its greater availability, lower cost, and higher accuracy.

OBJECTIVE: This study aimed to determine the quality of life (QOL), in patients with endometriosis ± infertility (B and C groups) and compare those to healthy women, and also infertile groups without endometriosis as a control groups (A and D), considering the fact that endometriosis and infertility reduces the quality of life in patients. METHODS: The present prospective comparative study was carried out between January 2018 and September 2020. A total of 400 women were included (100 women in each group). The participants filled in a validated questionnaire of quality of life, Endometriosis Health Profile-30 (EHP-30), and a visual analog scale of pain used, at the first visit, and 3 months after the medical or surgical treatment in the endometriosis group without infertility, additionally. RESULTS: The majority of the patients were married, categorized in the middle-class of socio-economic state and housewives. They were of Persian descent. BMI was high in the infertile groups; however, the time of infertility was not different between the two groups of B and C (P = 0.054). The mean score of QOL was significantly lower in B, C, and D groups in comparison to the healthy women as the control group (A) (P < 0.001). Moreover, the infertile group (B), in comparison to endometriosis ± infertility groups (C and D), had the lowest mean score of QOL (P < 0.001). In each group, those who were older and had better educational level reported a better quality of life than other participants in that group. Social support plays a very important role in reducing the endometriosis related pain symptoms both before and after treatment. Three months after the treatment of endometriosis (D), a significant improvement was observed in all the aspects of QOL-related endometriosis. Nonetheless, the improvement of the quality of life in the surgical group was significantly higher than that in the medical treatment. The mean visual analog score of pain decreased from 62.22 ± 22.78, to 5.15 ± 2.73 following the surgical treatment (P < 0.001). CONCLUSION: The lowest quality of life belonged to the infertile group, followed by the endometriosis group. The quality of life of the endometriosis group improved after the treatment. Thus, endometriotic patients' treatment in terms of improvement of quality of life should be considered by all professional health care teams.

Objective: The present work aimed to investigate the feasibility, complications, recurrence rate, and infertility outcomes of the radical and conservative surgical methods for colorectal endometriosis in short- and long-term follow-ups. Methods: In this prospective study, the patients with confirmed diagnosis of colorectal DIE were included from March 2015 to March 2021, who were referred to an Endometriosis Surgery Center affiliated with Shiraz University of Medical Sciences (SUMS). Information on demographics, surgical approaches, intra-operative, and post-operative findings as well as complications were collected and compared. Six- and 12-month interviews were conducted to evaluate the functional outcomes of all the procedures. Results: Out of 3,111 patients who underwent endometriosis surgery, 837 (28.19%) with the average age of 34.2 ± 5.9 years and average ASRM score of 102.1 ± 36.8 had rectosigmoid endometriosis. Laparoscopic rectal shaving was performed in 263(30.0%) patients while 326 (37.2%) underwent segmental bowel resection, and 248 (28.30%) were treated with disc excision. Prophylactic ileostomy was performed in six (0.68%) patients and peritonitis was reported in four (0.45%). Five (0.58%) subjects developed rectovaginal fistula and one (0.11%) was diagnosed with bladder atonia. The recurrence rate was 3.8%, 1.2%, and 0.3% in rectal shaving, disc, and segmental bowel resection techniques, respectively. Dysmenorrhea, dyspareunia, and dyschezia were improved after surgery by 7.3, 9.4, and 12.5 times, respectively. We observed 25.2% of total pregnancy following the operation, the majority of which occurred in the first year after the surgery. Conclusion: There were very few short-term or long-term complications in the three different techniques when the choice was correct.
RESUMO
The flow of granular materials through narrow openings governs flow and process efficiency in a variety of industrial settings. As the use of soft particles and other soft micro-materials becomes more widespread in consumer products, we seek to understand characteristics of granular flows beyond powder flows. We study clogging through a 2D hopper in systems consisting of a combination of soft and rigid particles of different sizes and mixing fractions. Our experimental results show that soft particles play a lubricating role in the flow of rigid spheres due to their deformability and slick surface, but the size of rigid particles influences clogging more than the size of soft ones. We simulate our results using a modification of the Durian bubble model to accommodate mixtures of particles of different softness. Without any adjustable parameters, the simulation results capture the clogging probability of soft-rigid particle mixtures through a 2D hopper.
RESUMO
RESEARCH QUESTION: Does injecting vasopressin into the mesovarium during endometrioma cystectomy further preserve postoperative ovarian reserve by reducing intraoperative bleeding and electrocoagulation points? DESIGN: Randomized controlled trial conducted between March 2016 and March 2020. One hundred and twenty patients with unilateral and unilobulated endometrioma were included and divided into two groups: group 1 (nâ¯=â¯60) comprised all patients with ovarian cystectomy after vasopressin injection in the mesovarium space; group 2 included the controls. In both groups, the anti-Müllerian hormone (AMH) concentration was examined before surgery and 3, 6 and 12 months after surgery. In both groups, the number of bipolar cauterization points and the amount of bleeding during cystectomy as well as the pain symptoms related to endometriosis and pregnancy rate were further assessed and compared. RESULTS: Compared with the vassopressin group, the controls had significantly higher haemostasis points and bleeding (Pâ¯=â¯0.0001). No significant difference was found between the two groups in serum AMH concentration at 3, 6 and 12 months after surgery. A significant reduction in pain symptoms was reported in both groups 6 months after surgery (Pâ¯=â¯0.0001). No significant difference was found between the two groups in spontaneous pregnancy, miscarriage rate and pregnancy time after surgery. CONCLUSION: Despite the reduction in the amount of bleeding and electrocoagulation points in the vasopressin group, ovarian reserve had a similar downward trend in both groups, which is attributed to the nature of these cysts.

PURPOSE: The authors compared assisted reproductive technique (ART) outcomes and the recurrence rate of endometrioma in the infertile patients undergoing sclerotherapy vs laparoscopic ovarian cystectomy. METHODS: In this prospective cross-sectional study, a total of 101 infertile patients, with unilateral endometriomas, were divided into two groups. The first group (n = 57) underwent ART after 1 year of unsuccessful spontaneous pregnancy after laparoscopic ovarian cystectomy; the second group (n = 44) had ethanol sclerotherapy (EST) at the time of oocyte retrieval. The authors measured the number of oocytes, clinical pregnancy rate (CPR), live birth rate (LBR), complication, and recurrence of endometriomas as the primary and secondary outcomes. RESULTS: The two groups had no significant differences in baseline characteristics and ovarian stimulation markers and also total number of oocytes. 42.1% and 34.1% of the patients (n = 24 and 15) had clinical pregnancy, and 38.6% and 29.5% (n = 22 and 13) had live birth following ART cycles in the surgery group and sclerotherapy group (P = .41, 0.34). The recurrence rates were 14.0% and 34.1% in the surgery and sclerotherapy groups (P = .017, X 2 = 5.67). CONCLUSIONS: Ethanol sclerotherapy can be a good alternative to surgery concerning the treatment of endometrioma; however, the recurrence of the disease in this group is significantly higher.
RESUMO
The current study was designed to evaluate the relationship between adenomyosis and its subtypes with endometriotic lesions (ovarian endometrioma (OMAs) and posterior deep infiltrative endometriosis (DIE)), to examine the probability of existence of a common cause of these mysterious diseases, and to evaluate the accuracy, sensitivity, and specificity of both transvaginal ultrasonography (TVS) and MRI in diagnosis of adenomyotic uterus. In this retrospective cross-sectional study, we selected 154 women with coexistence of endometriosis and adenomyosis according to their imaging, intraoperative, or pathological findings who were nominated for laparoscopic surgery. Eighty-six patients with just DIE resection without LH (laparoscopic hysterectomy) (group 1), and 68 patients with LH + DIE resection (group 2). The accuracy, sensitivity, and specificity of ultrasonographic and MRI findings for diagnosing adenomyosis were 72.1%, 77.6%, 40.0% and 49.2%, 41.5%, 90.0% respectively. So, TVS is a more sensitive diagnostic tool for diagnosing adenomyosis. However, MRI was more specific than TVS in the diagnosis of diffuse adenomyosis especially with simultaneous presence of uterine leiomyoma. Regarding the association of different types of adenomyosis (focal and diffuse) with different endometriosis lesions (OMA and posterior compartment DIE), we just found diffuse type of adenomyosis more frequent in the absence of rectal and rectovaginal septum (RVS) DIE (p ≤ 0.05). In addition to the questionable different nature of rectal and RVS DIE lesion, there is no relationship between adenomyosis subtypes and endometriotic lesions.

The novel coronavirus was recognised in December 2019 and caught humanity off guard. The virus employs the angiotensin-converting enzyme 2 (ACE2) receptor for entry into human cells. ACE2 is expressed on different organs, which is raising concern as to whether these organs can be infected by the virus or not. The testis appears to be an organ enriched with levels of ACE2, while the possible mechanisms of involvement of the male reproductive system by SARS-CoV-2 are not fully elucidated. The major focus of the present studies is on the short-term complications of the coronavirus and gains importance on studying the long-term effects, including the possible effects of the virus on the male reproductive system. The aim of this review was to provide new insights into different possible mechanisms of involvement of male gonads with SARS-CoV-2 including investigating the ACE2 axis in testis, hormonal alterations in patients with COVID-19, possible formation of anti-sperm antibodies (ASA) and subsequently immunological infertility as a complication of SARS-CoV-2 infection. Finally, we suggest measuring the sperm DNA fragmentation index (DFI) as a determiner of male fertility impairment in patients with COVID-19 along with other options such as sex-related hormones and semen analysis. Invasion of SARS-CoV-2 to the spermatogonia, Leydig cells and Sertoli cells can lead to sex hormonal alteration and impaired gonadal function. Once infected, changes in ACE2 signalling pathways followed by oxidative stress and inflammation could cause spermatogenesis failure, abnormal sperm motility, DNA fragmentation and male infertility.

BACKGROUND: Endometriosis is seen in 0.5%-5% of fertile and 25%-40% of infertile women. To investigate this conflict between gynecologists that ovarian endometriomas should be removed or not before making any decision about pregnancy among infertile women, the authors decided to carry out a systematic review and meta-analysis to compare the effect of various available therapeutic methods and notice the impact of these options on women's pregnancy rate. METHODS: This review is based on PRISMA recommendations with an electronic search using the following databases: PubMed, Scopus, Google scholar, etc, from 2000 to 2018, in the English language. The studies compare pregnancy rate based on four different treatment types of OMAs between infertile women: (surgery + ART, surgery + spontaneous pregnancy, aspiration ± sclerotherapy + ART, and ART alone). MAIN FINDINGS: At least eight prospective studies were included, in which 553 infertile women were compared in terms of treatment methods of OMAs before trying to become pregnant. CONCLUSION: Treatments are usually based on the patient's clinical condition and must be individual, with the purpose of relieving pain, improving fertility, or both. The authors do not have not any significant difference between our four groups of study; however, the success of surgical procedure compared to other methods was higher and the success of ART alone was the least.
RESUMO
PURPOSE: Studies showed anti-inflammatory and immunomodulatory effects of macrolide antibiotics such as clarithromycin in endometriosis. Therefore, the present study aims to investigate the therapeutic efficacy of clarithromycin in patients with endometriosis. METHODS: This was a double-blinded randomized placebo-controlled trial conducted on endometriotic women during March 2016-2017 in Dena Hospital, Shiraz, Iran. Immediately after surgery, the patients were randomly divided into clarithromycin (real) (n = 120) and placebo group (n = 169). The real group received 500 mg of clarithromycin everyday for 6 months and the placebo group received the placebo. The serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-10 (IL-10), Erythrocyte sedimentation rate (ESR) and C-reactive protein as well as clinical symptoms at baseline and 3 and 6 months of post-surgery were compared within and between groups. RESULTS: The scores of dysmenorrhea, dyschezia, dyspareunia, and non-menstrual pain significantly decreased in both real and placebo groups compared with the baseline values. However, the real group showed greater reductions compared with the placebo group (p < 0.001). Similarly, the serum levels of CRP, TNF-α, and IL-10 decreased in both groups compared with the baseline values, but the real group showed greater reductions. Interestingly, the reductions in the clinical symptoms and serum levels did not significantly differ between the real and placebo groups. Moreover, the reductions in the studied variables showed no dependence on the time. CONCLUSION: Clarithromycin may be an appropriate treatment in endometriotic patients. However, the non-significant differences between the real and placebo groups necessitate further studies on the therapeutic efficacy of clarithromycin.

Although endometriosis is not a newly discovered disease, it has still remained enigmatic. Understanding the pathophysiology of this disease is still one of the challenges of gynecology and reproductive medicine. Therefore, the subject of endometriosis treatment faces many questions to be answered. Even though this is not considered to be a rare disease, testing novel treatments on subjects is definitely contrary to medical ethics. This is where importance of animal studies is emphasized. History of animal studies on endometriosis dates back to the time when the young John Sampson presented his theory of retrograde flow of menstruation to the gynecologic society of his time to explain the mechanism of endometriosis. However, most of the medical society of that time favored metaplasia as the main mechanism over the new theory. In order to prove Sampson's theory, animal models were used to induce endometriosis, and that was the first study of experimental endometriosis. Nowadays, although no one uses animals to evaluate Sampson theory of endometriosis, however, experimental endometriosis is widely used to study many different aspects of the disease from pathogenesis to possible options for treatments. Also, since then, various animals and different techniques have been proposed and so there is a huge body of literature on experimental endometriosis. Contrary to many countries, Iranian medical societies have neglected animal models for endometriosis until recently. This review article aims to go through the prominent articles on the subject and introduce different animals and methods to its readers and have a special look at Iranian literature on experimental endometriosis.

The objective of the study is to determine the effects of clomiphene citrate (CC) on preventing premature luteinizing hormone (LH) surge in infertile patients with polycystic ovary syndrome (PCOS) undergoing intrauterine insemination (IUI). This was a randomized clinical trial being performed at Shiraz Mother and Child Hospital. We included 162 women with PCOS selected for IUI cycles. Patients were randomly allocated to receive 150 mg/day CC from the 8th of the cycle though the day of human chorionic gonadotropin (hCG) injection (n = 81) or nothing in the same period (n = 81). Main outcomes included the incidence of premature LH surge, pregnancy rate, abortion and ongoing pregnancy rates, number of maturing follicles, and endometrial thickness. The incidence of premature LH surge was significantly lower in those who received CC (3.0% vs. 14.9%; P = 0.021). The pregnancy rate was 10 (15.1%) and 6 (8.9%) in CC and control groups, respectively (P = 0.342). The ongoing pregnancy rate found to be comparable between two study groups (12.1% vs. 5.9%; P = 0.068). Serum level of estradiol (E2) level at the time of hCG administration was significantly higher in those who were treated with CC when compared to control (1153.5 ± 326.4 vs. 943.2 ± 215.3; P < 0.001). Patients who received CC also had higher number of mature follicles >18 mm when compared to controls (3.85 ± 1.3 vs. 2.94 ± 1.01; P < 0.001). Administration of CC from the 8th day of the cycle to the day of hCG injection in combination with Gonal-f in infertile patients with CC-resistant PCOS undergoing IUI cycles is associated with decreased incidence of premature LH surge, higher E2levels, and higher number of mature ovarian follicles. This protocol is safe and simple and could be considered to be cost-effective.
