Öğe Does Varicocele Repair Improve Conventional Semen Parameters? A Meta-Analytic Study of Before-After Data(Korean Soc Sexual Medicine & Andrology, 2024) Cannarella, Rossella; Shah, Rupin; Hamoda, Taha Abo-Almagd Abdel-Meguid; Boitrelle, Florence; Saleh, Ramadan; Gul, Murat; Rambhatla, AmarnathPurpose: The purpose of this meta-analysis is to study the impact of varicocele repair in the largest cohort of infertile males with clinical varicocele by including all available studies, with no language restrictions, comparing intra-person conventional semen parameters before and after the repair of varicoceles. Materials and Methods: The meta-analysis was performed according to PRISMA-P and MOOSE guidelines. A systematic search was performed in Scopus, PubMed, Cochrane, and Embase databases. Eligible studies were selected according to the PICOS model (Population: infertile male patients with clinical varicocele; Intervention: varicocele repair; Comparison: intra-person before-after varicocele repair; Outcome: conventional semen parameters; Study type: randomized controlled trials [RCTs], observational and case-control studies). Results: Out of 1,632 screened abstracts, 351 articles (23 RCTs, 292 observational, and 36 case-control studies) were includ-ed in the quantitative analysis. The before-and-after analysis showed significant improvements in all semen parameters after varicocele repair (except sperm vitality); semen volume: standardized mean difference (SMD) 0.203, 95% CI: 0.129-0.278; p<0.001; I2=83.62%, Egger's p=0.3329; sperm concentration: SMD 1.590, 95% CI: 1.474-1.706; p<0.001; I2=97.86%, Egger's p<0.0001; total sperm count: SMD 1.824, 95% CI: 1.526-2.121; p<0.001; I2=97.88%, Egger's p=0.0063; total motile sperm count: SMD 1.643, 95% CI: 1.318-1.968; p<0.001; I2=98.65%, Egger's p=0.0003; progressive sperm motil-ity: SMD 1.845, 95% CI: 1.537%-2.153%; p<0.001; I2=98.97%, Egger's p<0.0001; total sperm motility: SMD 1.613, 95% CI 1.467%-1.759%; p<0.001; l2=97.98%, Egger's p<0.001; sperm morphology: SMD 1.066, 95% CI 0.992%-1.211%; p<0.001; I2=97.87%, Egger's p=0.1864. Conclusions: The current meta-analysis is the largest to date using paired analysis on varicocele patients. In the current meta-analysis, almost all conventional semen parameters improved significantly following varicocele repair in infertile patients with clinical varicocele.Öğe Foetal cardiac function in third trimester pregnancies with reduced fetal movements(Taylor & Francis Inc, 2022) Saglam, Aylin; Derwig, Iris; Gul, Murat; Kasap, Burcu; Yilmaz, Nuh; Sezik, Mekin; Celik, OnderThe objective of our study was to investigate the possible relationship between poor perinatal outcome and foetal cardiac functions in pregnant women with reduced foetal movements (RFM). This cross-sectional study included 126 pregnant women with normal foetal movements (Group 1, Controls) and 42 pregnant women over 32 weeks gestation with RFM (Group 2). Group 2 was further divided into two subgroups according to their perinatal outcome: normal perinatal outcome (Group 2a) and poor perinatal outcome (Group 2b). Cardiotocography, the E/A ratio in both atrioventricular valves, myocardial performance index (MPI) and foetal tricuspid annular plane systolic excursion (f-TAPSE) were evaluated. Foetuses with poor perinatal outcome had a higher MPI (p = .003), higher tricuspid and mitral E/A (p < .001), and lower f-TAPSE values (p < .001). In regression analysis, f-TAPSE was the only parameter (p = .04) independently associated with poor perinatal outcome. In conclusion, examining f-TAPSE may predict adverse perinatal outcome in pregnancies with RFM.IMPACT STATEMENT What is already known on this subject? Reduced foetal movement (RFM) is associated with adverse pregnancy outcome. Cardiotocography, amniotic fluid assessment, estimated birthweight, foetal Doppler and formal foetal movement count (kick chart) are generally used in the clinical assessment of pregnancies with reduced foetal movements. These tests, we currently use to assess foetal wellbeing in women with reduced foetal movements, have limited sensitivity in predicting foetal compromise. What do the results of this study add? Foetal cardiac Doppler may potentially be used as an important adjunct to the conventional management of women with a perception of reduced foetal movements. What are the implications of these findings for clinical practice and/or further research? Foetal echocardiographic evaluation, such as f-TAPSE, may influence clinical practice by enabling improved risk stratification for poor perinatal outcome, thus allowing more timely definitive intervention. This could help to decrease the rate of stillbirth related to reduced foetal movements. The few established echocardiographically derived parameters, which can asses global right ventricle function, are not always easy to obtain, however, f-TAPSE is easily obtainable using ultrasound and it appears to be a clinically useful echocardiographic measurement of right ventricular function.Öğe Global Practice Patterns and Variations in the Medical and Surgical Management of Non-Obstructive Azoospermia: Results of a World-Wide Survey, Guidelines and Expert Recommendations(Korean Society for Sexual Medicine and Andrology, 2024) Rambhatla, Amarnath; Shah, Rupin; Ziouziou, Imad; Kothari, Priyank; Salvio, Gianmaria; Gul, Murat; Hamoda, TahaPurpose: Non-obstructive azoospermia (NOA) is a common, but complex problem, with multiple therapeutic options and a lack of clear guidelines. Hence, there is considerable controversy and marked variation in the management of NOA. This survey evaluates contemporary global practices related to medical and surgical management for patients with NOA. Materials and Methods: A 56-question online survey covering various aspects of the evaluation and management of NOA was sent to specialists around the globe. This paper analyzes the results of the second half of the survey dealing with the management of NOA. Results have been compared to current guidelines, and expert recommendations have been provided using a Delphi process. Results: Participants from 49 countries submitted 336 valid responses. Hormonal therapy for 3 to 6 months was suggested before surgical sperm retrieval (SSR) by 29.6% and 23.6% of participants for normogonadotropic hypogonadism and hypergonadotropic hypogonadism respectively. The SSR rate was reported as 50.0% by 26.0% to 50.0% of participants. Interestingly, 46.0% reported successful SSR in <10% of men with Klinefelter syndrome and 41.3% routinely recommended preimplantation genetic testing. Varicocele repair prior to SSR is recommended by 57.7%. Half of the respondents (57.4%) reported using ultrasound to identify the most vascularized areas in the testis for SSR. One-third proceed directly to microdissection testicular sperm extraction (mTESE) in every case of NOA while others use a staged approach. After a failed conventional TESE, 23.8% wait for 3 months, while 33.1% wait for 6 months before proceeding to mTESE. The cut-off of follicle-stimulating hormone for positive SSR was reported to be 12-19 IU/mL by 22.5% of participants and 20-40 IU/mL by 27.8%, while 31.8% reported no upper limit. Conclusions: This is the largest survey to date on the real-world medical and surgical management of NOA by reproductive experts. It demonstrates a diverse practice pattern and highlights the need for evidence-based international consensus guidelines.

High sensitive troponin T (Hs-TnT) measurement is a novel and sensitive method. The aim of this study was to investigate if Hs-TnT levels are a predictor of major adverse cardiovascular events (MACE) in the first year after a successful elective PCI in patients with stable angina pectoris (SAP). Material and methods: 100 patients who presented with SAP and underwent successfully elective PCI were included in the study. Patients with elevated troponin I levels (>0.1 ng/mL) before the procedure excluded from the study. Hs-TnT levels were measured before the procedure and at 3-4 hours (h) (early period) and 12-24 hours (late period) after the procedure and Hs-TnT level >14 pg/mL was considered positive. The incidence of MACE during the first year was recorded. Results: Hs-TnT levels were positive in 36% of the patients in the early period and in 54% of the patients in the late period. The incidence rate of MACE for the first year was significantly higher in the patients with positive Hs-TnT levels in the early period but not the late period (36.1% vs. 15.6%; p = 0.026) and logistic regression analysis yielded an odds ratio of 3.36. Conclusion: Hs-TnT levels measured 3-4 h after a successful elective PCI in patients with SAP can predict the incidence of MACE within the first year. Nonetheless, these results must be corroborated by other larger studies.
