Abstract
Introduction: There is no clear evidence in the literature that platelet-rich plasma (PRP) injections improve female sexual dysfunction (FSD) and female stress urinary incontinence (SUI). Objectives: A systematic review was performed to study the efficacy and safety of PRP injections in women with the above pathologies, as well as to explore the optimal dosing, frequency and area of injections, and duration of treatment. Methods: A systematic search on PubMed, Embase and the Cochrane Library database was performed, as well as sources of grey literature from the date of database or source creation to January 2023. After title/abstract and full-text screening, clinical studies on humans evaluating the efficacy of PRP in gynecological disorders using standardized tools were included. Risk of bias was undertaken with RoB-2 for randomized-controlled trials (RCT) and the Newcastle-Ottawa Scale (NOS) for observational studies. Results: Four prospective and one retrospective study explored FSD, while six prospective and one RCT evaluated female SUI. A total of 327 women with a mean age of 51 ± 12 years were included. For FSD, PRP significantly improved the Female Sexual Function Index (FSFI), the Vaginal Health Index (VHI) and the Female Sexual Distress score (FSDS). For SUI, PRP led to a significant improvement in the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and the Urogenital Distress Inventory (UDI-6). The identified RCT reported a significantly higher mean score of ICIQ-SF (p < 0.05) and UDI-6 (p < 0.01) in the midurethral sling group compared to the PRP injections group. Regarding the risk of bias, the RCT was characterized by high risk, whereas the observational studies were of moderate risk. The protocol for PRP injections for FSD is the injection of 2 mL of PRP into the distal anterior vaginal wall once a month for 3 months. For female SUI, 5-6 mL of PRP should be injected into the periurethral area once a month for 3 months. Conclusions: Despite the promising initial results of PRP injections, the level of current evidence is low due to methodological issues in the available studies. It becomes clear that there is an emerging need for high-quality research examining PRP injections for the treatment of FSD and female SUI.

Frontiers in endocrinology. 2023;14:1183209
Abstract
OBJECTIVE This meta-analysis aims to evaluate the efficacy and safety of autologous platelet-rich plasma (PRP) administration in reducing adhesion recurrence and improving pregnancy outcomes in patients with intrauterine adhesion (IUA). METHODS We conducted a comprehensive search of Pubmed, Embase, the Cochrane Library, Web of Science, Scopus, and China National Knowledge Internet (CNKI) from inception to February 10, 2023, without any language or regional restrictions. We used random-effects models to assess odds ratios (OR) and weight mean differences (WMD) with 95% confidence intervals (CI). RESULTS Our meta-analysis included a total of 730 patients from 10 clinical studies (6 RCTs and 4 non-RCTs). The results showed that PRP administration significantly increased endometrial thickness (WMD = 0.79, 95% CI: 0.40-1.19; P < 0.001; I(2) = 0.0%), menstrual volume (WMD = 2.96, 95% CI = 2.30-3.61; P < 0.001; I(2) = 0.0%), and days of menstruation (WMD = 1.13, 95% CI = 0.86-1.41; P < 0.001; I(2) = 0.0%). Additionally, the clinical pregnancy rate was also improved (OR = 1.82, 95% CI: 1.19-2.78; P = 0.006; I(2) = 0.0%). However, there was insufficient evidence to reach a conclusion regarding the effects of PRP on the recurrence rate of moderate to severe IUA, changes in AFS scores, miscarriage rate, and live birth rate. CONCLUSIONS Our analysis confirms that autologous PRP is an effective treatment for IUA. However, the limited sample size suggests that the results should be interpreted with caution. Therefore, larger and well-designed studies are necessary in the future to confirm these findings and explore the optimal PRP dosing regimens further.

Hu S, Jin Z, Tang Q
Geburtshilfe und Frauenheilkunde. 2023;83(4):453-462
Abstract
Purpose This meta-analysis was conducted to systematically retrieve relevant randomized controlled trials (RCTs) and evaluate the effects of intrauterine infusion of autologous platelet-rich plasma (PRP) in women with thin endometrium, implantation or pregnancy failure undergoing treatment with assisted reproductive technology (ART). Methods We conducted a systematic review and meta-analysis of the retrieved RCTs. Studies on the intrauterine infusion of PRP in women undergoing treatment with ART that were published in PubMed, the Cochrane library, Web of Science, and Embase from inception until June 2022 were included. The data were extracted and analyzed independently using the fixed-effects or random-effects model according to heterogeneity. Results Seven RCTs involving 861 patients (435 in the intervention group and 426 in the control group) were included. The rates of clinical pregnancy (risk ratio [RR]: 2.51; 95% confidence interval [CI]: 2.0-3.13; PÂ <Â 0.00001), chemical pregnancy (RR: 1.96; 95% CI: 1.58-2.45; PÂ <Â 0.00001), live births (RR: 7.03; 95% CI: 3.91-12.6; PÂ <Â 0.00001), and implantation (RR: 3.27; 95% CI: 1.42-7.52; PÂ =Â 0.005) were significantly higher in the women who received PRP infusion than in the control group. No significant differences were noted in the miscarriage rate (RR: 0.98; 95% CI: 0.39-2.42; PÂ =Â 0.96) between the two groups. Conclusion In summary, intrauterine infusion of PRP may be an effective therapy for women with thin endometrium and recurrent implantation failure (RIF) undergoing treatment with ART. More population-based RCTs are warranted to verify the efficacy of our evidence.

Soliman, A., Elsonbaty, S., Saleh, Y., Hegazy, D., Faragallah, H. M.
Turkish journal of obstetrics and gynecology. 2023;20(2):154-163
Abstract
Repeated implantation failure refer to failure to conceive after three or more embryo transfer attempts. Several interventions were offered to improve maternal and fetal outcomes. Our objective was to investigate the impact of platelet-rich plasma (PRP) as a promising intervention to improve both pregnancy and birth outcomes. We searched PubMed, Scopus, Web of Science, and Cochrane Central, in addition to other relevant resources of grey literature. Only clinical trials were eligible to be included. We performed the meta-analysis using a random effects model. Eight randomized clinical trials, enrolling 1038 women with more than 3 implantation failure attempts, were included. We found a significant increase regarding all our prespecified primary outcomes. Chemical pregnancy rate [relative ratio (RR): 1.96, 95% confidence interval (CI): 1.61, 2.39; p<0.001], clinical pregnancy rate (RR: 4.35, 95% CI: 1.92, 2.88; p<0.001), and live birth rate (RR: 4.03, 95% CI: 1.29, 12.63; p=0.02) were found to be statistically significant and increased in patients who received PRP compared with the control group. Implantation rate (RR: 1.98, 95% CI: 1.34, 2.75; p<0.001), miscarriage rate (RR: 0.44, 95% CI: 0.23, 0.83, p=0.01), and multiple pregnancy rate (RR: 2.56, 95% CI: 1.02, 6.42, p=0.04) were also found to be significantly increased in the PRP group. We provide strong evidence on how intrauterine PRP can improve implantation, pregnancy, and birth outcomes in RIF women, which should direct clinicians to consider this intervention as a very effective tool in assisted reproductive techniques.

Abstract
BACKGROUND Platelet-rich plasma (PRP) is an autologous platelet concentration recently used in the reproductive field. Studies had conflicting results regarding its effect on pregnancy outcomes. We aimed to solve the debate on the safety and efficacy of PRP in women undergoing assisted reproduction and assess the influence of covariates on the outcomes of PRP infusion. METHODS We searched PubMed, Scopus, Cochrane, and Web of Science in May 2023. We included randomized and non-randomized clinical trials as well as cohort studies assessing intrauterine PRP in sub fertile women undergoing assisted reproduction (IVF/ICSI). For the quality assessment, We used the Cochrane Risk of Bias Tool 1, the ROBINS-I tool, and the Newcastle-Ottawa Scale. We pooled the data using RevMan version 5.4. RESULTS The data from 23 studies were pooled. PRP had favorable outcomes compared with the control group on clinical pregnancy rate (RR: 1.84, 95% CI 1.62 to 2.09; P < 0.00001), live birth rate (RR: 1.75, 95% CI: 1.24 to 2.47; P = 0.001), and miscarriages (RR: 0.51, 95% CI: 0.36 to 0.72; P = 0.0002). Women with repeated implantation failure had a significantly improved clinical pregnancy rate (RR: 1.83, 95% CI: 1.49 to 2.24; P < 0.00001), live birth rate (RR:1.83, 95% CI: 1.33 to 2.51; P = 0.002), and miscarriage rate (RR: 0.46, 95% CI: 0.31 to 068; P = 0.0001). CONCLUSION PRP showed promising results in assisted reproductive techniques. Further large and multicenter RCTs are required to compare the doses of PRP while identifying the specific population with the most benefits from PRP.

Obstetrics and gynecology. 2023;141(1):49-58
Abstract
OBJECTIVE To evaluate red blood cell use during delivery in patients with placenta accreta spectrum. DATA SOURCES We searched MEDLINE, EMBASE, CINAHL, Cochrane Central, ClinicalTrials.gov, and Scopus for clinical trials and observational studies published between 2000 and 2021 in countries with developed economies. METHODS OF STUDY SELECTION Abstracts (n=4,275) and full-text studies (n=599) were identified and reviewed by two independent reviewers. Data on transfused red blood cells were included from studies reporting means and SDs, medians with interquartile ranges, or individual patient data. The primary outcome was the weighted mean number of units of red blood cells transfused per patient. Between-study heterogeneity was assessed with an I2 statistic. Secondary analyses included red blood cell usage by placenta accreta subtype. TABULATION, INTEGRATION, AND RESULTS Of the 599 full-text studies identified, 20 met criteria for inclusion in the systematic review, comprising 1,091 cases of placenta accreta spectrum. The number of units of red blood cells transfused was inconsistently described across studies, with five studies (25.0%) reporting means, 11 (55.0%) reporting medians, and four (20.0%) reporting individual patient data. The weighted mean number of units transfused was 5.19 (95% CI 4.12-6.26) per patient. Heterogeneity was high across studies (I2=91%). In a sensitivity analysis of five studies reporting mean data, the mean number of units transfused was 6.61 (95% CI 4.73-8.48; n=220 patients). Further quantification of units transfused by placenta accreta subtype was limited due to methodologic inconsistencies between studies and small cohort sizes. CONCLUSION Based on the upper limit of the CI in our main analysis and the high study heterogeneity, we recommend that a minimum of 6 units of red blood cells be available before delivery for patients with placenta accreta spectrum. These findings may inform future guidelines for predelivery blood ordering and transfusion support. SYSTEMATIC REVIEW REGISTRATION PROSPERO, CRD42021240993.

Platelet-Rich Plasma Intrauterine Infusion as Assisted Reproduction Technology (ART) to Combat Repeated Implantation Failure (RIF): A Systematic Review and Meta-Analysis
Huang, C., Ye, X., Ye, L., Lu, L., Liu, F.
Iranian journal of public health. 2023;52(8):1542-1554
Abstract
BACKGROUND Repeated implantation failure (RIF) is considered one of the major challenges facing clinician in assisted reproduction technologies (ART) despite the significant advances that have been made in this field. Platelet rich plasma (PRP), also known as autologous conditioned plasma, is a protein concentrate with anti-inflammatory and pro-regenerative characteristics. The use of PRP in women undergoing ART has been studied in the past, with varying degrees of success. The goal of this trial was to see if injecting PRP into the uterus improves pregnancy outcomes in women receiving ART. METHODS PubMed, Embase, Scopus, Web of Science, and the Cochrane Database of Clinical Trials were among the databases searched (CENTRAL), from 2015 to 2021. The pooled estimates were calculated using a meta-analysis with a random-effects model. There were 14 studies with a total of 1081 individuals (549 cases and 532 controls). RESULTS There was no difference in miscarriage rates between women who got PRP and those who received placebo (P≤0.90). Chemical pregnancy (P≤0.00), clinical pregnancy (P ≤0.001), and implantation rate (P≤ 0.001) were all significantly higher in women. Endometrial thickness increased in women who got PRP vs women who received placebo after the intervention (P ≤0.001). CONCLUSION PRP may be an alternate therapeutic approach for individuals with thin endometrium and RIF, according to the findings of this comprehensive study. To determine the subgroup that would benefit the most from PRP, more prospective, big, and high-quality randomized controlled trials (RCTs) are needed.

Abstract
BACKGROUND Foetal anaemia is caused by a severe pregnancy complication, haemolytic disease of the foetus and newborn. Intrauterine transfusions (IUTs) are performed to treat foetal anaemia in alloimmunised pregnant women. If left untreated hydrops can develop thereby reducing the chance of survival. Survival rates have improved but the procedure is not without complications. Procedure-related complications can be associated with early gestational age, hence delaying IUT could improve outcomes. This review aims to determine the effectiveness and safety of IUTs by examining survival and mortality rates, procedure-related complications with associated foetal mortality and the influence of hydrops. STUDY DESIGN AND METHOD A systematic review was conducted by searching keywords in four scientific databases from January 2000 to April 2022. A meta-analysis was performed with the OpenMeta-Analyst software using an arcsine transformed proportion with the binary random-effects model and maximum likelihood method. RESULTS Fifteen studies were identified as eligible and used in the meta-analysis. The forest plots all showed statistically significant outcomes with heterogeneity of data. Results indicated a greater foetal survival rate with IUT to treat anaemic foetuses, a low foetal mortality rate, and low risk of procedure-related complications associated with foetal loss but a higher risk of foetal mortality when hydrops is present. CONCLUSION The findings of this systematic review and meta-analysis provide evidence that IUT is a safe and effective treatment for foetal anaemia in the absence of hydrops when experienced personnel perform the procedure to minimise the risk of procedure-related complications.

Abstract
BACKGROUND Growing evidence suggests low and high maternal hemoglobin (Hb) concentrations may have adverse consequences for maternal and child health. There remain questions on specific Hb thresholds to define anemia and high Hb as well as how cutoffs may vary by anemia etiology and timing of assessment. METHODS We conducted an updated systematic review (using PubMed and Cochrane Review) on low (< 110 g/L) and high (≥ 130 g/L) maternal Hb concentrations and associations with a range of maternal and infant health outcomes. We examined associations by timing of Hb assessment (preconception; first, second, and third trimesters, as well as at any time point in pregnancy), varying cutoffs used for defining low and high hemoglobin concentrations and performed stratified analyses by iron-deficiency anemia. We conducted meta-analyses to obtain odds ratios (OR) and 95% confidence intervals. RESULTS The updated systematic review included 148 studies. Low maternal Hb at any time point in pregnancy was associated with: low birthweight, LBW (OR (95% CI) 1.28 (1.22-1.35)), very low birthweight, VLBW (2.15 (1.47-3.13)), preterm birth, PTB (1.35 (1.29-1.42)), small-for-gestational age, SGA (1.11 (1.02-1.19)), stillbirth 1.43 (1.24-1.65)), perinatal mortality (1.75 (1.28-2.39)), neonatal mortality (1.25 (1.16-1.34), postpartum hemorrhage (1.69 (1.45-1.97)), transfusion (3.68 (2.58-5.26)), pre-eclampsia (1.57 (1.23-2.01)), and prenatal depression (1.44 (1.24-1.68)). For maternal mortality, the OR was higher for Hb < 90 (4.83 (2.17-10.74)) than for Hb < 100 (2.87 (1.08-7.67)). High maternal Hb was associated with: VLBW (1.35 (1.16-1.57)), PTB (1.12 (1.00-1.25)), SGA (1.17 (1.09-1.25)), stillbirth (1.32 (1.09-1.60)), maternal mortality (2.01 (1.12-3.61)), gestational diabetes (1.71 (1.19-2.46)), and pre-eclampsia (1.34 (1.16-1.56)). Stronger associations were noted earlier in pregnancy for low Hb and adverse birth outcomes while the role of timing of high Hb was inconsistent. Lower Hb cutoffs were associated with greater odds of poor outcomes; for high Hb, data were too limited to identify patterns. Information on anemia etiology was limited; relationships did not vary by iron-deficiency anemia. CONCLUSION Both low and high maternal Hb concentrations during pregnancy are strong predictors of adverse maternal and infant health outcomes. Additional research is needed to establish healthy reference ranges and design effective interventions to optimize maternal Hb during pregnancy.
PICO Summary
Population
Women during pregnancy or preconception (148 studies, n= 13,839,327).
Intervention
Updated systematic review on low (< 110 g/L) and high (≥ 130 g/L) maternal haemoglobin (Hb) concentrations and associations with adverse maternal and infant health outcomes.
Comparison
Outcome
Low maternal Hb at any time point in pregnancy was associated with: Low birthweight, very low birthweight (VLBW), preterm birth (PTB), small-for-gestational age (SGA), stillbirth, perinatal mortality, neonatal mortality, postpartum haemorrhage, transfusion, pre-eclampsia, and prenatal depression. For maternal mortality, the OR was higher for Hb < 90 (OR, 4.83; 95% CI [2.17, 10.74]) than for Hb < 100 (OR, 2.87; 95% CI [1.08, 7.67]). High maternal Hb was associated with: VLBW, PTB, SGA, stillbirth, maternal mortality, gestational diabetes, and pre-eclampsia. Stronger associations were noted earlier in pregnancy for low Hb and adverse birth outcomes while the role of timing of high Hb was inconsistent.

Mardiyan Kurniawati, E., Anisah Rahmawati, N., Hardianto, G., Paraton, H., Hastono Setyo Hadi, T.
International journal of reproductive biomedicine. 2023;21(12):957-974
Abstract
BACKGROUND Management for pelvic floor disorders needs to be improved. Platelet-rich plasma (PRP) offers an innovative treatment in general medical care to promote cell regeneration. OBJECTIVE This review aims to investigate the role of PRP in pelvic floor disorders. MATERIALS AND METHODS 6 international databases were accessed using several keywords namely PubMed, Science Direct, Cochrane Library, ProQuest, Google Scholar, and Scopus. The inclusion criteria were articles written in English, published in 10-yr period from 2012 until 2022, and investigated the relevant topic. This systematic review followed PRISMA guideline. RESULTS 644 articles were found in several databases and 15 articles met the criteria. Management for pelvic floor disorders needs to be improved, but there are still many challenges, such as less effective treatments, risk of recurrence, and postoperative wound healing. PRP offers an innovative treatment in general medical care to promote cell regeneration. A total of 644 articles from the database were found, but 15 studies met the criteria. A total of 600 women with various pelvic floor disorders treated with PRP were analyzed. PRP positively impacts female sexual dysfunction, perineal trauma, vulvovaginal atrophy, stress urinary incontinence, vesicovaginal fistula, perineal rupture, and pelvic organ prolapse. Dosages, preparation techniques, injection techniques, and additive materials are varied. Most studies do not report side effects from the therapy, but the urinary disorder complaints must be paid attention to. CONCLUSION PRP can be used to manage pelvic floor disorders. Future studies should clarify and standardize the dose in each case and how to make PRP produce the best results.
