Publication Mesh complications on youtube(Elsevier, 2020-09-01) Orhan, Adnan; ORHAN, ADNAN; Göktürk, Gözde Güner; Özerkan, Kemal; ÖZERKAN, KEMAL; Kasapoglu, Işıl; KASAPOĞLU, IŞIL; Aslan, Kiper; ASLAN, MÜNİR KİPER; Uncu, Gurkan; UNCU, GÜRKAN; Tıp Fakültesi; Kadın Hastalıkları ve Doğum Ana Bilim Dalı; 0000-0002-7558-8166; 0000-0002-9277-7735; K-2269-2016; AAH-9791-2021; AER-7173-2022; AAH-9694-2021; AAT-3479-2021; V-5292-2019Objective: There has been a heated discussion about mesh materials in urogynecology in recent years. The role of social media in this discussion is critical. This study aims to make a systematic analysis of videos uploaded to YouTube about mesh complications in urogynecology.Study Design: YouTube was searched using specific terms about mesh materials. The primary outcome was the relationship between the video characteristics-which were publisher identity, attitude, the main focus of the video country, and year- and the mesh debate in urogynecology.Results: We analyzed 1128 YouTube videos about mesh complications. There was no distinction between stress urinary incontinence and pelvic organ prolapse when referring to the mesh material in 79 % of the videos. 35.2 % of the videos were in the News group, 31.2 % were in the Patients group, 19.6 % were in the Doctors group, and 14.0 % were in the Lawyers group. Videos in the News (75.7 %), Patients (92.6 %), and Lawyers (99.4 %) groups mostly had a negative attitude, while videos in the Doctors (48.9 %) group mostly had an informative attitude. News (43.2 %) and Patients (51.2 %) group videos were predominantly from the United Kingdom. However, Lawyers (81.0 %) and Doctors (44.3 %) videos were predominantly from the USA. In the last three years, the news and patients videos have increased by an average of 40 % each year.Conclusion: YouTube has influenced the mesh dilemma with a negative attitude. As long as social media is at the center of this discussion, a healthy outcome cannot be achieved.Publication Evaluation of endometrioma pathophysiology and related ovarian damage by PTEN / AKT apoptosis signaling pathway(Elsevier Science, 2020-09-01) Şen, Furkan; Aslan, Kiper; Kuşpınar, Göktan; Çakır, Cihan; Kasapoglu, Işıl; Avcı, Berrin; Uncu, Gürkan; ŞEN, HAMZA FURKAN; ASLAN, MÜNİR KİPER; KUŞPINAR, GÖKTAN; ÇAKIR, CİHAN; KASAPOĞLU, IŞIL; AVCI, BERRİN; UNCU, GÜRKAN; Tıp Fakültesi; Kadın Hastalıkları ve Doğum Ana Bilim Dalı; 0000-0002-9277-7735; 0000-0002-8332-7353; AAH-5119-2021; AAT-3479-2021; HTQ-5866-2023; AER-7173-2022; AAH-9694-2021; AAH-5249-2021; KEU-2073-2024; CXJ-7203-2022; ELU-2357-2022Publication Does gonadotropin dose adjustment in inadequate ovarian response during controlled ovarian hyperstimulation improve the live birth rates of patients with diminished ovarian reserve?(Oxford Univ Press, 2022-07-01) Mesut, O.

This was a retrospective cohort study including 2425 sibling oocytes in 259 ICSI cycles. ICSI was performed on 104 GV (germinal vesicle) oocytes which had reached the metaphase II (MII) stage (Group 1) and 231 MI oocytes which had reached the MII stage (Group 2) following IVM (in vitro maturation). Immediate ICSI was applied following oocyte aspiration on 292 MI stage (Group 3) and 1798 MII stage oocytes (Group 4). Normal fertilisation rates in Groups 1, 2, 3 and 4 were 51.9%, 39%, 30.1% and 59.5%, respectively. The rates of blastocyst development per oocyte and per zygote were calculated as 3.8%, 3.0%, 6.8%, 14.1% and 7.4%, 7.7%, 22.7%, 23.6% for Groups 1, 2, 3 and 4, respectively. The blastocyst development rate was significantly higher in the MI-ICSI group compared with other immature oocytes. Even though performing ICSI on the oocytes at the MI stage on the day of oocyte aspiration resulted in lower fertilisation rates, it was associated with significantly higher rates of blastocyst development.Publication Does the presence of endometriosis cause a challenge for transvaginal oocyte retrieval? A comparison between patients with and without endometriosis(Galenos Yayıncılık, 2018-03-12) Kasapoğlu, Işıl; Türk, Pınar; Dayan, Aylin; Uncu, Gürkan; KASAPOĞLU, IŞIL; Türk, Pınar; Dayan, Aylin; UNCU, GÜRKAN; Tıp Fakültesi; Kadın Hastalıkları ve Doğum Ana Bilim Dalı; AAT-3479-2021; CXJ-7203-2022; JJP-1980-2023; ETO-8465-2022Objective: The aim of the study was to compare patients with and without endometriosis regarding performance rates, difficulties, and complications associated with transvaginal oocyte retrieval (TVOR) procedures.Material and Methods: A prospective cohort study was conducted at the In Vitro Fertilization Unit of the Division of Reproductive Endocrinology and Infertility Department of a university hospital. Fifty-eight patients with endometriosis and 61 patients without endometriosis underwent TVOR procedures consecutively. Primary outcome measures were; number of needle entries per patient and performance rating defined as the total number of oocytes retrieved per vaginal needle entry. The requirement for manual compression of the abdominal wall (assistance) to reach the ovaries, procedure-related pain, and procedural complications were also evaluated.Results: The median number of needle entries through the vaginal wall per patient was comparable between the two groups (p=0.45). Performance rates were higher in the control group (p=0.001). Performance rates and total number of the needle entries through the vaginal wall were not significantly correlated with ovarian endometrioma (OMA) diameter (r=0.28; p=0.68; r=0.275, p=0.068, respectively) in the endometriosis group. Body mass index (BMI) scores were found to be correlated with the number of the needle entries and higher BMI scores were associated with higher numbers of vaginal wall punctures (p< 0.001). The requirement for manual compression of the abdominal wall was significantly higher in the control group (57.4% vs 27.6%, p=0.001). A similar proportion of women needed analgesic medications after the TVOR procedure in both groups (10.3% vs 16.9%, p=0.33). Hospital readmissions for any symptoms were also comparable between the two groups (p=0.22). Three women were treated for pelvic infection, all of whom were in the endometriosis group.Conclusion: Endometriosis seems to cause a challenge for TVOR that may have reflection on individual surgeon's performance rates for the procedure, independently from the diameter of a pre-existing OMA or ovarian adhesions. Obesity is another factor that may present a challenge for the procedure.Publication Amh levels may predict for mullerian anomalies and pregnancy outcomes patients with pcos.(Elsevier, 2020-09-01) Aslan, Kiper; ASLAN, MÜNİR KİPER; Albayrak, Özge; Bilgiç, Kübra Özlem; BİLGİÇ, KÜBRA ÖZLEM; Kasapoglu, Işıl; KASAPOĞLU, IŞIL; Avci, Berrin; AVCI, BERRİN; Uncu, Gurkan; UNCU, GÜRKAN; Tıp Fakültesi; Kadın Hastalıkları ve Doğum Ana Bilim Dalı; 0000-0002-9277-7735; AAH-9694-2021; AER-7173-2022; AAT-3479-2021Publication The kisspeptin and kisspeptin receptor in follicular microenvironment: Is that really necessary for oocyte maturation and fertilisation?(Taylor & Francis Inc, 2022-08-19) Kuşpinar, Göktan; KUŞPINAR, GÖKTAN; Çakır, Cihan; ORAL, HALUK BARBAROS; ÇAKIR, CİHAN; KASAPOĞLU, IŞIL; Sarıbal, Seda; BUDAK, FERAH; Budak, Ferah; Avcı, Berrin; Uncu, Gürkan; UNCU, GÜRKAN; AVCI, BERRİN; Tıp Fakültesi; İmmunoloji Ana Bilim Dalı; 0000-0002-8332-7353; 0000-0001-7625-9148; IZP-9398-2023; AAH-5249-2021; F-4657-2014; HTQ-5866-2023The aim of this study was to determine whether Kisspeptin and Kisspeptin receptor in the follicular microenvironment is necessary for human oocyte maturation and fertilisation. The cumulus cell (CC) and follicle fluids (FF) obtained from the first aspirated follicles (n = 52) from 32 patients were divided into three groups considering nuclear maturation and fertilisation results of oocytes: (1) Metaphase I or germinal vesicle stage oocytes (incomplete nuclear maturation, n = 10), (2) unfertilised metaphase II oocytes (incomplete cytoplasmic maturation, n = 16), and (3) fertilised metaphase II oocytes (completed nuclear-cytoplasmic maturation, n = 26). The gene expression levels were assessed by RT-PCR. The levels of Kisspeptin (KISS1) and Kisspeptin receptor (KISS1R) were measured by ELISA. There were no significant efficacy KISS1 and KISS1R gene expressions in cumulus cells in terms of oocyte nuclear maturation stage (Group 1, vs Group 2 + Group 3) (respectively p = .49; p = .45). In terms of the cytoplasmic maturation stage (Group 2, vs Group 3); KISS1 and KISS1R expressions in CCs were comparable (respectively p = .07; p = .08). In FFs, KISS1 and KISS1R concentrations were similar between all groups (respectively p = .86; p = .26). In conclusion, the relative KISS1 and KISS1R expressions in CC and also KISS1 and KISS1R level of FF were independent of oocytes nuclear and/or cytoplasmic maturation. Impact statement What is already known on this subject? It has been demonstrated that Kisspeptin is an essential regulator of reproductive function and plays a key role in the modulation of GnRH secretion and gonadotropin release. Still, no information is available about the link between gene expression or concentration in the follicular microenvironment and oocyte development. What do the results of this study add? The study has shown that the relative Kisspeptin (KISS1) and Kisspeptin receptor (KISS1R) and expressions in cumulus cell (CC) and also KISS1 and KISS1R levels of follicle fluids (FF) were independent of oocytes nuclear and/or cytoplasmic maturation. What are the implications of these findings for clinical practice and/or further research? Based on the findings, it is difficult to establish a concept that kisspeptin can directly induce oocyte maturation. Nevertheless, to confirm these findings, further studies with a larger sample size are needed.Publication Preliminary results of the DINE study (Dienogest vs. norethindrone acetate in endometriosis treatment)(Oxford Univ Press, 2023-06-01) Gürbüz, Tansu Bahar; Uncu, Gürkan; Aslan, K.; Gadirli, Z.; Kasapoğlu, Işıl; GÜRBÜZ, TANSU BAHAR; UNCU, GÜRKAN; Aslan, K.; Gadirli, Z.; KASAPOĞLU, IŞIL; Tıp Fakültesi; Doğum ve Jinekoloji Bilim Dalı; GXB-3440-2022; GER-9626-2022; GLW-2086-2022; JDO-9798-2023; CXJ-7203-2022Publication Which is more predictive ovarian sensitivity marker if there is discordance between serum anti-Mullerian hormone levels and antral follicle count? A retrospective analysis(Taylor & Francis Inc, 2022-01-07) Aslan, Kiper; Kasapoğlu, Işıl; Çakır, Cihan; Koç, Meltem; Çelenk, Murat Deniz; Ata, Barış; Avcı, Berrin; Uncu, Gürkan; ASLAN, MÜNİR KİPER; KASAPOĞLU, IŞIL; ÇAKIR, CİHAN; KOÇ ÇAKAR, MELTEM; ÇELENK, MURAT DENİZ; AVCI, BERRİN; UNCU, GÜRKAN; Tıp Fakültesi; Kadın Hastalıkları ve Doğum Ana Bilim Dalı; 0000-0002-9277-7735; 0000-0002-8332-7353; 0000-0001-6456-8779; AAT-3479-2021; AAH-5249-2021; AER-7173-2022; CXJ-7203-2022; EPE-7010-2022; ELU-2357-2022This retrospective study aims to determine the more predictive ovarian reserve marker when there is discordance between anti-Mullerian hormone (AMH) and antral follicle count (AFC) in patients with diminished ovarian reserve (DOR). Patients who underwent ICSI because of DOR were divided into three groups. Group 1: patients with low AMH (<1.1 ng/ml) and AFC (n < 7), group 2: patients with low AMH (<1.1 ng/ml) and normal AFC (n >= 7) and group 3: patients with normal AMH (>= 1.1 ng/dl) and low AFC (n < 7). Demographic values, follicle output rate (FORT) score and follicle to oocyte index (FOI) score of the groups were compared. Totally, 662 cycles were enrolled in the study. There were 418 cycles in group 1, 167 cycles in group 2 and 77 cycles in group 3. As the primary result, FORT and FOI scores were higher in group 3 than the other two groups. Median FORT Score with quartiles: group 1: 100 (66-150), group 2: 71 (57-100), group 3: 136 (96-200), p<.01 - median FOI score with quartiles: group 1: 83 (50-140), group 2: 71 (40-100), group 3: 116 (66-216), p<.01. In conclusion, serum AMH level has more predictive value for stimulation success if there is discordance with AFC.Impact Statement What is already known on this subject? Female age, serum Anti-Mullerian Hormone (AMH) levels, and antral follicle count (AFC) are commonly used to assess ovarian reserve and predict response to ovarian stimulation. AMH and AFC are both positively correlated with ovarian reserve. What do the results of this study add? If there is discordance between AFC and AMH in patients with diminished ovarian reserve (DOR), the ovarian response is better in patients with high AMH and low AFC than the patients with low AMH and high AFC. What are the implications of these findings for clinical practice and/or further research? It is important to assess both AFC and AMH before controlled ovarian hyperstimulation, to predict ovarian response in DOR patients, rather than assessing AFC or AMH alone.
