Value of intrauterine platelet-rich concentrates in patients with intrauterine adhesions after hysteroscopy: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: To evaluate the value of intrauterine platelet-rich concentrates among patients with intrauterine adhesions (IUAs) after hysteroscopic adhesiolysis. METHODS: Four different databases (PubMed, Cochrane Library, Scopus, and ISI web of science) were searched for the available studies from inception to November 2021. We selected randomized clinical trials (RCTs) that compared platelet-rich concentrates in the intervention group versus no injection of platelet-rich concentrates in the control group among women with intrauterine adhesions after operative hysteroscopy. Revman software was utilized for performing our meta-analysis. Our primary outcomes were the adhesion score and incidence of recurrence of severe intrauterine adhesions postoperatively. Our secondary outcomes were the clinical pregnancy rate, menstrual flow duration in days, and menstrual flow amount (number of pads). RESULTS: Five RCTs met our inclusion criteria with a total number of 329 patients. We found that platelet-rich concentrates were linked to a significant reduction in the postoperative adhesion score (MD = -1.00, 95% CI [-1.68, -0.32], p = 0.004). Moreover, there was a significant reduction in the incidence of severe IUAs recurrence among the platelet-rich concentrates group (7.6%) compared to the control group (23.4%) after hysteroscopy (p = 0.001). The clinical pregnancy rate was significantly increased among the platelet-rich concentrates group (37.1%) in comparison with the control group (20.7%) after hysteroscopic adhesiolysis (p = 0.008). There were significant improvements in the menstrual flow duration and amount among the platelet-rich concentrates group (p < 0.001). CONCLUSIONS: Intrauterine placement of platelet-rich concentrates is an effective method for the treatment of intrauterine adhesions after hysteroscopy.

The impact of music therapy on anxiety and pregnancy rate among infertile women undergoing assisted reproductive technologies: a systematic review and meta-analysis.

Objective: We aimed to perform a systematic review and meta-analysis to evaluate the effect of music therapy on anxiety and pregnancy rates among infertile women undergoing to perform assisted reproductive technologies (ART).Methods: Cochrane Library, PubMed, ISI web of science, and Scopus were searched from inception to May 2021. We included randomized controlled trials (RCTs) that compared music therapy (intervention group) to no music intervention (control group). Our primary outcomes were anxiety score using the State-Trait Anxiety Inventory (STAI) tool and pain score utilizing the Visual Analog Scale (VAS). Our secondary outcomes were the overall satisfaction score and clinical pregnancy rate. We extracted the available data from included studies and pooled them in a meta-analysis model using RevMan software. The overall quality of evidence was assessed through GRADEpro GDT software.Results: Seven RCTs with a total number of 793 patients were included in our study. Music therapy significantly reduced the anxiety score compared to control group (MD= -3.09, 95% CI [-5.57, -0.61], p = 0.01). Moreover, pain score was significantly improved after music treatment (MD= -2.93, 95% CI [-3.86, -2.00], p > 0.001). A significant improvement in the overall satisfaction score was found among music therapy group (MD= 1.51, 95% CI [0.40, 2.61], p = 0.008). Although more women in music therapy group experienced an increase in the clinical pregnancy rate in comparison with control group, the result was not statistically significant (RR= 1.08, 95% CI [0.94, 1.26], p = 0.28). The GRADEpro GDT tool showed a moderate quality of evidence for the evaluated outcomes.Conclusions: There is evidence of moderate quality that music therapy improves anxiety, pain, and satisfaction scores among infertile women undergoing ART. Moreover, it increases the clinical pregnancy rate but without statistical significance. More trials with a larger sample size are needed to investigate the influence of music therapy on the clinical outcomes of ART.

Androgen receptor gene methylation and exon one CAG repeat length in ovarian cancer: differences from breast cancer.

More than one neoplastic founder clone can exist in benign epithelial tumours. Although theories of clonal selection make pluriclonality appear unlikely in carcinomas, published data do not exclude this possibility. This study looked for evidence of multiclonal X inactivation in ovarian carcinoma using AR methylation as a marker. Fifteen unifocal ovarian carcinomas and 14 multifocal carcinomas all in Scottish patients were studied. One representative formalin-fixed paraffin-embedded tumour block was chosen for each of the former and two for the latter. From each of these 43 tumour blocks three samples each of approximately 10(4) carcinoma cells were obtained by microdissection (129 in all). DNA released by proteinase K digestion was subjected to PCR amplification of the androgen receptor gene AR exon I CAG repeat polymorphism with and without prior digestion with methylation-sensitive restriction enzymes HpaII and HhaI. Complex amplification patterns were consistent with mosaic X inactivation in some ovarian carcinomas but acquired anomalies of AR methylation cannot be excluded. Parallel analysis of other X-linked polymorphic loci would strengthen the inference of clonality status from DNA methylation data in tumour X studies. Strikingly, the number of CAG repeats in the 29 ovarian tumour patients (median 16, range 11 - 20) was substantially fewer than in 34 previously studied breast cancer patients from the same scottish population (median 21, range 14 - 26; P < 0.0001), and women homozygous for the AR CAG repeat were over-represented in the ovarian cancer patients but not in the breast cancer series. These findings reinforce recent suggestions that AR may have a role in ovarian carcinogenesis.
