Acta Obstet Gynecol Scand 2023; 102:1431-1439. [PMID: 37475190 PMCID: PMC10577622 DOI: 10.1111/aogs.14634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 05/29/2023] [Accepted: 05/30/2023] [Indexed: 07/22/2023]
Abstract
INTRODUCTION This meta-analysis aimed to evaluate the efficacy and safety of low-molecular-weight heparin (LMWH) on pregnancy outcomes in thrombophilic women receiving in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). MATERIAL AND METHODS A systematic literature search of PubMed, EMBASE, the Cochrane Library, and China National Knowledge Infrastructure was performed to identify randomized controlled trials (RCTs) comparing LMWH with no treatment or placebo published from database inception until February 19, 2023. Primary outcomes were the clinical pregnancy rate and implantation rate, and secondary outcomes were the live birth rate, miscarriage rate, and the risk of bleeding events. The certainty of the evidence was rated using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) system. Meta-analysis was conducted using STATA 14.0. RESULTS Five RCTs involving 1094 thrombophilic women receiving IVF/ICSI were finally included. Administration of LMWH was associated with statistically higher clinical pregnancy rate (4 RCTs, risk ratio [RR] 1.50, 95% confidence interval [CI] 1.23-1.82, p < 0.001, low certainty evidence), implantation rate (5 RCTs, RR 1.49, 95% CI 1.25-1.78, p < 0.001, very low certainty evidence), and live birth rate (2 RCTs, RR 2.15, 95% CI 1.60-2.89, p < 0.001, very low certainty evidence), but with statistically lower miscarriage rate (2 RCTs, RR 0.36, 95% CI 0.15-0.86, p = 0.021, very low certainty evidence). However, using LMWH was linked to a higher risk of bleeding events (2 RCTs, RR 2.36, 95% CI 1.49-3.74, p < 0.001, very low certainty evidence). CONCLUSIONS Very low certainty evidence suggests that administration of LMWH may benefit pregnancy outcomes in thrombophilic women receiving IVF/ICSI treatment, although it may also increase the risk of bleeding events. However, before putting our findings into practice, healthcare professionals should conduct an in-depth evaluation of the available evidence and specific patient situations. Furthermore, due to the low methodological quality of the included studies, more high-quality studies are needed to validate our findings in the future.

Abstract
Thrombophilia is a group of inherited or acquired coagulation disorders that have been associated with reproductive failure. However, there are still no clear recommendations on whether its inclusion in the initial study of the infertile couple or patients with recurrent implantation failure is necessary. In this discussion paper, based on a SWOT (strengths, weaknesses, opportunities, threats) analysis, the different aspects of the repercussions of thrombophilia screening and treatment in reproduction are evaluated. To avoid possible subjectivity in the analysis and results of this study, researchers followed Oxford criteria for the evaluation of evidence. The results from the evaluation of the reviewed bibliography seem to indicate that, pending new evidence, it would be advisable not to include thrombophilia screening in the initial baseline study of the infertile couple. There is no evidence to support a clear association between thrombophilia and implantation failure or infertility. Thrombophilia testing in this setting may increase cost, with minimal potential benefit and lead to inappropriate use of anticoagulants with possible deleterious adverse effects. Future well-designed studies are needed to assess the possible benefit of anticoagulant therapy in infertile thrombophilic patients with implantation failure.

Abstract
Background A number of publications have examined the relation between blood group and female infertility including ovarian reserve, recurrent miscarriage, and live birth. However, there is a lack of literature investigating joint mother/father ABO blood type in a large cohort. This study aimed to investigate the association between couple combinations for ABO blood groups and assisted reproductive technology (ART) outcomes in patients undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI). Methods This retrospective cohort study included 30,717 couples who underwent IVF cycles between 2010 and 2019. The clinical outcomes of IVF treatment were the primary outcome. History of spontaneous miscarriage, embryo quality, and birth sex, weights, defects rate were also studied. Results There was no difference in the baseline demographics between the blood type groups. There was a statistically significant positive association between the combination of female blood type AB and male blood type AB with biochemical pregnancy, clinical pregnancy, and live birth rate (OR 1.36; 95% CI, 1.05–1.78; P = 0.02 and OR 1.31; 95% CI, 1.0–1.68; P = 0.031 and OR 1.28; 95% CI, 1.01–1.63; P = 0.041 respectively). No statistically significant difference was observed between joint mother/father ABO blood types and high-quality embryo rate, early abortion rate, birth sex, birth weights, and birth defect rate. Conclusions Our findings suggest that the success rate of IVF/ICSI cycles in parent mating AB blood type is higher than that in other blood type combination groups.

Abstract
The aim of our study was to investigate the effect of maternal and embryo MTHFR C677T and A1298C polymorphisms on embryo aneuploidies and mosaicism and the correlation between these genetic variants in transferred euploid embryos and IVF outcomes. MTHFR genotype was analyzed in 77 women who performed an IVF/ICSI cycle with PGT-A. Moreover, to evaluate the effect of embryo MTHFR polymorphisms on embryo aneuploidies and mosaicism, the MTHFR genotype was analyzed in 191 biopsied embryos from the PGT-A cycles of these patients. Additionally, 218 DNA samples from trophectoderm biopsies belonging to a different group of patients were also genotyped. MTHFR polymorphisms were analyzed in a total amount of 409 trophectoderm samples. The main parameters analyzed were embryo aneuploidy and mosaicism rates. Finally, the IVF outcomes of 241 single euploid embryo transfers were assessed and compared between different MTHFR embryo genotypes. The aneuploidy rates were similar in embryos from homozygous normal women and women with at least one mutated allele (54.7% vs. 30.2% in 677C>T and 37.8% vs. 42.7% in 1298A>C). Furthermore, no differences were observed in the mosaicism rate (24.0% vs. 13.8% in 677C>T and 17.1% vs. 17.3% in 1298A>C). A similar analysis was performed, taking into account the embryo genotype results. No differences in aneuploidy rate were observed between the study groups. The only significant difference was the mosaicism rate among 677C>T genotype (13.5% in 677CC group vs. 5.4% in 677CT/TT; p = 0.019). Implantation rate, biochemical and clinical miscarriage rates, and ongoing pregnancy rate were compared between different embryo genotypes, and no statistically significant differences were found. In conclusion, the maternal MTHFR genotype did not influence embryo chromosomal abnormalities. Moreover, the embryo MTHFR genotype was not associated with embryo aneuploidy or IVF outcomes such as implantation, pregnancy loss, and ongoing pregnancy when euploid embryos were transferred.Abbreviations: MTHFR: methylenetetrahydrofolate reductase; IVF: in vitro fertilization; PGT-A: preimplantation genetic testing for aneuploidies; SAM: S-adenosyl methionine; SNP: single nucleotide polymorphism; SPSS: Statistical Package for Social Sciences; RIF: recurrent implantation failure; RPL: recurrent pregnancy loss; hCG: human chorionic gonadotropin; PBS: phosphate buffered saline; CGH: comparative genomic hybridization; NGS: next generation sequencing.

Abstract
Alongside an interplay of a multitude of factors, attainment of a favorable pregnancy outcome is predicated on successful implantation, which in itself is a complex process anchored by balanced interchange with the hemostatic system. Among other etiologies, failure of implantation can result in infertility, and lead affected couples to consider assisted reproductive technology (ART) in an effort to fulfill their desire for procreation. Given the critical role of the hemostatic system in the process of implantation, documentation of a hypercoagulable state during controlled ovarian stimulation in the context of in vitro fertilization, as well as the potential association of its derangement in the setting of thrombophilia, with infertility, ART, ovarian hyperstimulation syndrome, and failure of implantation are explored. Additionally, current evidence addressing the relationship between ART and thromboembolism is examined, as is the role of therapy with heparin and aspirin to decrease thrombotic risk and improve ART-related pregnancy outcomes. Evidence-based recommendations from relevant professional societies are summarized.

Abstract
Importance Infertility poses a substantial public health problem for women of reproductive age, in the United States and globally. Infertility can be overcome with a variety of emerging assisted reproductive technologies (ARTs). In vitro fertilization (IVF) currently represents the most commonly utilized method of ART and is typically associated with the highest clinical pregnancy rate and live birth rate compared with other infertility treatment options. However, proper preconception evaluation and counseling is paramount for optimizing IVF and pregnancy outcomes. Objective This article aims to outline current guidelines and recommendations for comprehensive preconception evaluation before initiation of IVF. Evidence Acquisition Articles were obtained from PubMed, ACOG committee opinions 781 and 762, and relevant textbook chapters. Results A variety of recommendations and best practices exist for optimally managing patients seeking IVF. Special attention must be paid to the workup of certain patient populations, such as those with age older than 35 years, uterine abnormalities, comorbidities (especially hypertension, diabetes, and thrombophilias), and obesity. In addition, many lifestyle factors must be addressed before IVF initiation, such as smoking, illicit drug use, and inadequate nutrition. Preconception counseling and expectation management is key to optimizing pregnancy outcome. Conclusion and Relevance A myriad of patient and environmental factors impact the potential success rates of IVF in treating infertility. Providers must be equipped to provide data-driven, patient-centered counseling before initiation of IVF.

Abstract
BACKGROUND Even though thrombophilias are associated with negative pregnancy outcomes (PO), there is not a consensus of when thrombophilias should be screened for, or how they affect placental vascularization during pregnancy. Therefore, the main aim of this study was to discover inherited thrombophilias (IHT) in the first trimester in women with otherwise no indications for thrombophilia screening, based on their vascularization parameters. LMWH treatment in improvement of placental vascularization and PO was also assessed. Finally, the classification of thrombophilias based on observed obstetric risks was proposed. METHODS Women were included in study based on their poor gestational sac and later utero-placental juncture vascularization signal and screening for inherited thrombophilias. LMWH were then initiated and Resistance index of Uterine artery (RIAU) was followed alongside PO (preterm birth, preeclampsia, placental abruption, intrauterine growth reduction). Study group consisted of women with combined inherited thrombophilias. Control group consisted of patients with inherited thrombophilias who have received LMWH therapy since pregnancy beginning. FINDINGS Out of 219 women, 93 had IHT, and 43 had combined IHT. All pregnancies both in both groups ended up with live births. Vaginal birth was more present in the control group (p < .001), and all women in study group delivered by CS. Premature birth was present in 8.4% of patients in control group, and in 32.55% of the patients in the study (p < .001). PE wasn't noted, and only 1 case of PA in control group. In the control group, 6.5% patients had IUGR, and 32.55% in the study group (p < .05). Based on RIAU and PO, thrombophilia categories were established: S (severe), MO (moderate), MI (mild) and L (low). Higher risk thrombophilias had higher RIAU later in the pregnancy, earlier pregnancy termination and Intrauterine Growth Reduction (IUGR). CONCLUSIONS Thrombophilias should be considered and screened when poor vascularization is noted early in the pregnancy with Doppler sonography. Intervention with LMWH prevents adverse PO in these patients.

Abstract
OBJECTIVE Reproductive clinics are often faced with cases of repeated implantation failure (RIF). This study evaluated whether platelet-rich plasma (PRP) might improve the implantation outcomes of patients suffering from RIF. METHODS Thirty women with RIF submitted to frozen-thawed embryo transfers were included in the study. Intrauterine infusions of autologous purified platelet preparations were administered 48 hours prior to embryo transfer. Differences in implantation, clinical pregnancy, and miscarriage rates of cycles with and without PRP infusions were analyzed. RESULTS The implantation rate seen in the PRP group was 6.7%. No significant difference was found the between the implantation, clinical pregnancy, ongoing pregnancy, and miscarriage rates of frozen-thawed embryo transfers with and without PRP infusion. However, the effect size of PRP infusion (Cohen's d=0.39) on implantation rates revealed a relationship in medium strength. CONCLUSION Platelet-rich plasma might potentially yield beneficial effects as a safe therapeutic option offered alongside other treatments designed to improve the reproductive outcomes of women with repeated implantation failure.

Abstract
Background Spontaneous pregnancy loss and implantation failure after assisted reproductive technologies (ART) are very common occurrences. Although 50–60% of all cases remains unexplained, various predisposing factors, including thrombophilias, have been identified. Thus, the potential benefit of a prophylaxis with low-molecular-weight heparins in improving outcomes has been often investigated over the years. However, the majority of studies are observational and results from randomized clinical trials (RCTs) are inconclusive, probably due to heterogeneity and limited sample size. To cover these unmet needs and to have further data mainly based on the real-life clinical management, we designed these multicenter registries. Methods OTTILIA (Observational sTudy on antiThrombotic prevention in thrombophILIA and pregnancy loss) and FIRST (recurrent Failures in assIsted Reproductive Techniques) registries are two prospective, multicenter, observational studies to evaluate pregnancy or ART outcomes in consecutive women with previous reproductive failures after spontaneous or assisted conception, respectively. All enrolled women are observed from their first visit after positive pregnancy test (OTTILIA) or before commencing a new ART cycle (FIRST) until the end of pregnancy or ART procedure (negative pregnancy test/end of pregnancy, if successful cycle), respectively. Data are collected by means of questionnaires and recorded in a central database. Follow-up investigations are performed during hospital stay, routine clinical follow-up visits or telephone interviews. Primary outcome is live birth rate in the OTTILIA register and clinical pregnancy rate in the FIRST. Discussion Although RCTs are the ‘gold standard’ for evaluating treatment outcomes, we believe that our registries represent a valid alternative in improving knowledge on mechanisms involved in reproductive failures and supporting future clinical decisions. Trial registration NCT 02385461, retrospectively registered 5 March 2015 (OTTILIA); NCT 02685800, registered 10 February 2016 (FIRST).

[PMID: 31254142 DOI: 10.1007/s10815-019-01473-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2018] [Accepted: 05/02/2019] [Indexed: 12/12/2022] Open
Abstract
PURPOSE The aim is to summarize and evaluate current systematic reviews and meta-analyses on MTHFR polymorphisms in recurrent pregnancy loss (RPL). METHODS We searched Pubmed and Embase databases and selected in form of PICOS (participants, interventions, comparisons, outcomes, and study design). Our methodology was registered on PROSPERO (CRD42017042762). Systematic reviews and meta-analyses containing primary studies were extracted for meta-analyses, along with their OR and 95%CI. We assessed the quality of the included studies using AMSTAR and OQAQ criteria. RESULTS Eleven systematic reviews and meta-analyses were identified. C677T was significantly related to RPL overall in Allele (OR, 95%CI 1.43, 1.29-1.60), Recessive (OR, 95%CI 1.66, 1.42-1.95), and Homozygous (OR, 95%CI 2.08, 1.66-2.61). There was no correlation observed between A1298C and RPL, except for in Heterozygous (OR, 95%CI 1.62, 1.17-2.25). CONCLUSIONS We identified a difference in the association between MTHFR C677T polymorphism and RPL, especially in Asian population. No significant correlation was found between A1298C and RPL.

Abstract
Background The shift towards hypercoagulation during in vitro fertilization (IVF) can lead to the impairment of embryo implantation and placental blood circulation, which is believed to be a factor in an unsuccessful IVF cycle. Objectives To assess coagulation in women with infertility before the start of an IVF cycle and during treatment to reveal the association between coagulation imbalance and IVF outcome. Patients/Methods We conducted a prospective cohort observational study including 125 participants who underwent fresh IVF cycles. Blood samples were collected at five time points: before IVF, one week after the start of controlled ovarian stimulation (COS), on the day of follicular puncture, on the day of embryo transfer (ET) and one week after ET. Coagulation tests (clotting times: activated partial thromboplastin time (APTT) and prothrombin; fibrinogen and D-dimer concentrations; thrombodynamics) were performed. Results Women with an elevated clot growth velocity (>32.3 μm/min, detected by thrombodynamics) before IVF demonstrated a higher risk of negative IVF outcomes (adjusted RR = 1.38; 95% CI 1.28–1.49; P<0.001). During the procedure, we observed increases in prothrombin, fibrinogen and D-dimer concentrations, a slight shortening of APTT and a hypercoagulation shift in the thrombodynamics parameters. The hemostasis assay values during COS and after ET had no associations with IVF outcomes. Conclusions Hypercoagulation in the thrombodynamics before the start of IVF treatment was associated with negative IVF outcomes. After the start of COS, all tests demonstrated a hypercoagulation trend, but the hypercoagulation did not influence IVF outcome. This research is potentially beneficial for the application of thrombodynamics assay for monitoring hemostasis in infertile women prior to an IVF procedure with the goal of selecting a group requiring hemostasis correction to increase the chances of pregnancy.

An observational multicentre study on the efficacy and safety of assisted reproductive technologies in women with rheumatic diseases. Rheumatol Adv Pract 2019; 3:rkz005.

Abstract
Objectives The aim was to determine whether assisted reproductive technologies (ARTs) confer additional risk in rheumatic patients (in terms of disease flare and fetal–maternal complications) and whether, if performed, their efficacy is affected by maternal disease. Methods Sixty infertile rheumatic women undergoing 111 ART cycles were included. Clinical pregnancy rate, live birth rate, maternal disease flares and maternal–fetal complications were recorded. Results One hundred and eleven ART cycles in 60 women were analysed. We reported 46 pregnancies (41.4%), 3 (3.1%) cases of ovarian hyperstimulation syndrome and no cases of thrombosis during stimulation, pregnancy and puerperium. One or more maternal complication was reported in 13 (30.2%) pregnancies, and fetal complications occurred in 11 fetuses (21.1%). The live birth rate was 98%, but we reported three (6%) perinatal deaths in the first days of life. During puerperium, we recorded one (2.5%) post-partum haemorrhage and one (2.5%) articular flare. Conclusion The safety and efficacy of the ARTs, demonstrated in the general population, seems to be confirmed also in rheumatic patients. No evidence was found to advise against their application, and the choice of therapy should be made depending on the patient’s risk profile, irrespective of whether the pregnancy is natural or artificial induced.

Abstract
Background: Antiphospholipid antibodies (aPL) have a multifaceted effect on the hemostatic system, damaging all its protective links.Aim: To study the effect of APA on outcomes of assisted reproductive technologies (ART).Study design: We examined 267 women with infertility, who planned pregnancy using ART. They included 178 women with IVF failure (I group) and 89 women with pregnancy after the IVF program (II group). The comparison group consisted of 80 pregnant women after IVF (male factor); a control group included 80 pregnant women with physiological pregnancy. Results of study demonstrated a high frequency of aPL circulation in a group of women with IVF failures. Overall, the proportion of aPL among all 267 women who planned pregnancy with ART was 32.6%. Elevated levels of aPL in the structure of causes of IVF failures (group I) were observed in 42.1% of them. Among women whose pregnancy occurred with ART (II group) the rate of APA was 19.1%. In the comparison group, in 6.3% of cases, aPL circulation was observed. In the control group, the rate was 3.4%.Conclusion: Considering the high percentage of aPL circulation in the case of IVF failures, authors think that high titers of aPL are a temporary contraindication for IVF. Patients with a history of aPL circulation are required to receive anticoagulant therapy from the first days of the hormonal protocol. The drug of choice is a group of low molecular weight heparins (LMWH). An individual approach is extremely important with the possible identification of causes of IVF failures and selective therapy, which leads to a significant improvement in the outcomes of the IVF program.

Abstract
Hereditary thrombophilias (HT) and undifferentiated connective tissue dysplasia (uCTD) are important causes of female infertility. Moreover, there are signs of their common pathogenesis: a number of proteins, such as PAI-1, play an important role in the pathogenesis of both conditions, as well as in the development of infertility in patients with HT and uCTD OBJECTIVE: To determine the morphological substrate and molecular mechanisms of impaired pregnancy outcomes in women with uCTD and HT. SUBJECT AND METHODS: A study group included 130 reproductive-aged female patients with primary infertility and a control group consisted of 11 patients (surrogate mothers). An endometrial pipelle biopsy sample was taken from each patient on days 6-8 after ovulation according to the ultrasound findings. The study group patients were divided into subgroups: 1A) infertility and HT (n=91); 1B) infertility, NT, and uCTD (n=19); 1C) infertility and uCTD (n=20).

Abstract
INTRODUCTION The effects of multiple inherited and acquired thrombophilic defects on the outcome of in-vitro fertilization (IVF) remain unexplored. The aim of this study was to evaluate the association between multiple thrombophilia and clinical outcomes in a large prospective cohort of women undergoing IVF. MATERIALS AND METHODS Consecutive women scheduled for IVF were eligible. The primary study outcome was live birth. Secondary outcomes included spontaneous abortion, clinical pregnancy, and symptomatic venous thromboembolism. RESULTS 687 women with a mean age of 34.6 (±3.2) years were included. Overall, 22 women (3.2%) had two or more thrombophilic defects. The probability of live birth was not statistically significantly different between women with ≥2 thrombophilia (odds ratio [OR] 0.62; 95% confidence interval [CI], 0.18 to 2.11) or ≥1 thrombophilia (OR 0.67;95% CI, 0.41 to 1.09) and women without any thrombophilia. None of the individual inherited thrombophilia nor positivity to antiphospholipid antibodies or lupus anticoagulant were associated with live birth. Single positivity for lupus anticoagulant carried a more than threefold higher risk of abortion (OR 3.74; 95% CI, 1.30 to 10.75). There were no statistically significant associations between individual or multiple thrombophilic defects and clinical pregnancy or pregnancy test results. No woman had a history of venous thromboembolism and none developed a thrombotic event during the study. CONCLUSIONS In women undergoing IVF, the presence of two or more thrombophilic defects was rare and showed no statistically significant associations with IVF outcomes.

Abstract
PURPOSE Retrospective and cross-sectional studies suggested that non-O blood group may be associated with failures of in vitro fertilization (IVF), but data remain controversial. The aim of this observational cohort study was to prospectively evaluate the effect of non-O blood type on clinical outcomes of IVF. METHODS Women < 40 years who underwent IVF and had ABO blood type recorded as part of the routine workup were eligible. The primary study outcome was live birth. Secondary outcomes included spontaneous abortion, positive pregnancy test, and clinical pregnancy. RESULTS A total of 497 women with a mean age of 34.6 (standard deviation 3.2) years were included. The mean number of embryos transferred was 2.3 (standard deviation 0.6). The most common ABO blood types were O (n = 213, 42.9%) and A (n = 203, 40.8%), while 63 (12.7%) and 18 (3.6%) women had the B and AB blood types, respectively. Differences in live birth (21.8 vs. 24.3%, odds ratio [OR] 1.17; 95% confidence intervals [CI], 0.76 to 1.78), positive pregnancy test (37.9 vs. 36.6%, OR 0.96; 95% CI, 0.66 to 1.38), clinical pregnancy (35.1 vs. 33.8%, OR 0.95; 95% CI, 0.66 to 1.39), and spontaneous abortion (12.3 vs. 9.2%, OR 0.72; 95% CI, 0.41 to 1.29) between women with O and non-O blood type were not statistically significant. CONCLUSIONS In a prospective cohort study, we confirmed the lack of a significant association between non-O blood type and clinical outcomes of IVF. Further studies are needed to clarify whether non-O blood group has any prognostic relevance in women undergoing IVF.

Abstract
Protein C global is a global dotting assay that evaluates abnormalities in the protein C anticoagulant pathway. A few studies have examined this assay in relation to assisted reproductive technology (ART), but its role in infertile women with in vitro fertilization (IVF) failure remains unclear. In this study, we assessed protein C in infertile women with a history of IVF failure who were undergoing ART. We examined 45 healthy fertile women who conceived naturally, and 45 infertile women with 2 or more implantation failures undergoing ART. Both protein C and activated protein C resistance (APC-R) were evaluated. The results showed that mean protein C expressed as a normalized ratio (PCAT-NR) was significantly lower in the study group compared to the control group (0.76 ± 0.15 vs. 0.91 ± 0.14, respectively; p = 0.0001). Follow-up on ART outcomes showed that women who failed ART had significantly lower PCAT-NR compared to successful cases. PCAT-NR did not correlate with APC-R levels in the study (r = 0.125, p < 0.5) or failed ART subgroups. Using logistic regression analysis, patients with lower PCAT-NR levels showed an elevated risk of implantation failure (p = 0.04, OR 0.50, 95% CI 0.26-0.84). In conclusion, protein C global assay may play a role in the etiology of IVF failure, which might be independent of APC-R. Larger studies are encouraged to validate these findings and explore the underlying pathophysiological mechanisms.

Abstract
Almost 1600 individuals from the Polish population were recruited to this study. Among them 319 were fertile couples, 289 were recurrent spontaneous abortion (RSA) couples, and 131 were in the group of recurrent implantation failure (RIF) following in vitro fertilization. The aim of this study was to evaluate the MTHFR c.c.677 C>T and c.c.1298 A>C polymorphisms’ association with RSA and RIF. We used PCR-RFLP with HinfI (677 C>T) and MboII (1298 A>C) digestion. We observed a protective effect of the female AC genotype (OR = 0.64, p = 0.01) and the C allele (AC+CC genotypes; OR = 0.65, p = 0.009) against RSA. Moreover, 1298 AA/677 CT women were more frequent in RSA (31.14%) and RIF (25.20%) groups in comparison to fertile women (22.88%), although this difference was significant only in the case of RSA (p = 0.022, OR = 1.52). Male combined genotype analysis revealed no association with reproductive failure of their partners. Nevertheless, the female/male combination AA/AC of the 1298 polymorphism was more frequent in RSA couples (p = 0.049, OR = 1.49). However, the significant results became insignificant after Bonferroni correction. In addition, analysis of haplotypes showed significantly higher frequency of the C/C haplotype (1298 C/677 C) in the female control group than in the female RSA group (p = 0.03, OR = 0.77). Moreover, the association between elevated homocysteine (Hcy) level in plasma of RSA and RIF women and MTHFR polymorphisms was investigated but did not reveal significant differences. In conclusion, for clinical practice, it is better to check the homocysteine level in plasma and, if the Hcy level is increased, to recommend patients to take folic acid supplements rather than undergo screening of MTHFR for 1298 A>C and 677 C>T polymorphisms.

Abstract
Infertility and subfertility, menstrual irregularities, and decreased parity may occur in women with autoimmune diseases due to multiple factors, including underlying inflammatory disease, gonadotoxic medications, and psychosocial issues related to living with chronic disease. Awareness of these factors, as well as validation and support of patients confronting reproductive challenges, is important for providing comprehensive care to these women. An understanding of the expanding options for fertility preservation strategies during gonadotoxic medications is essential. Referral to a reproductive endocrinology clinic is indicated in this patient population.

Abstract
The aim of the study was to investigate the combined impact of the genetic heterogeneity of the glycoproteins Ia (GpIa) and IIIa (GpIIIa) and the platelet-endothelial cell adhesion molecule-1 (PECAM-1) and P-Selectin genes on IVF embryo transfer implantation failures (IVF-ET failures). Sixty nulligravida women with previous IVF-ET failures and 60 fertile controls were genotyped for the GpIa-C807T, GpIIIa-PlA1/PA2, PECAM-1-C373G (Leu125Val) and P-Selectin-A37674C (Thr715Pro) polymorphisms by pyrosequencing. Compared with wild-type combined homozygotes, carriers of combinations of risk alleles in two gene loci were at significantly increased risk for IVF-ET failure, whereas carriers of the combination of GpIa-807T, GpIIIa-PlA2 and PECAM-1-373G alleles had OR = 52.50 (95%CI: 4.05-680.95, p < .001). The area under the receiver-operating characteristic curve (AUC) based on the number of polymorphisms and the number of risk alleles per subject was 75.4% (95%CI: 66.7%-82.8%, p < .001) and 72.5% (95%CI: 63.6%-80.3%, p < .001), respectively. The OR per polymorphism and risk allele increase was 4.26 (95%CI: 2.15-8.41, p < .001) and 2.85 (95%CI: 1.71-4.76, p < .001), respectively. The above associations were more robust among younger women. The combined analysis of these polymorphisms revealed strong association of combined carriers with IVF-ET failures especially for younger women and provided a genetic risk score with good diagnostic accuracy in the prediction of IVF-ET failures.

Abstract
INTRODUCTION The discovery of the factor V Leiden (FVL) missense mutation (Arg506Gln) causing factor V resistance to the anticoagulant action of activated protein C was a landmark that allowed a better understanding of the basis of inherited thrombotic risk. FVL mutation is currently the most common known hereditary defect predisposing to venous thrombosis. Areas covered: Novel data-driven FVL diagnosis and therapeutic approaches in the management of FVL carriers in various clinical settings. Brief conclusions on topics of direct clinical relevance including currently available indications for primary and secondary prophylaxis, the management of female, pediatric carriers and asymptomatic relatives. Latest evidence on the association between FVL and cancer, as well as the possible use of direct oral anticoagulant therapy. Expert commentary: Although FVL diagnosis nowadays is highly accurate, many doubts remain regarding the best management and therapeutic protocols. The main role of clinicians is to tailor therapeutic strategies to carriers and their relatives. High familial penetrance, distinctive aspects of the first thrombotic event (provoked/unprovoked, age, etc.) and laboratory biomarkers can guide the optimal management of secondary antithrombotic prophylaxis, primary prophylaxis in asymptomatic individuals, and whether to screen relatives.

Abstract
PURPOSE The aim of this study is to provide an overview of the studies investigating a possible association between thrombophilia and assisted reproductive technology (ART) outcome. METHODS This is a literature review. RESULTS Congenital thrombophilias (CoT) are reported to be associated with pregnancy loss. However, the association between CoT and early pregnancy loss is weak and does not necessarily support causation. CoT are more likely to be associated with late fetal loss. Even though data pooled from case-control and cohort studies suggest an increased risk of ART failure in women with CoTs, there seems no association when the analysis is confined to better quality cohort studies. The evidence supporting anticoagulation to improve ART outcome in CoT carriers is weak. Likewise, studies on antiphospholipid antibodies (APAs) and ART outcome suffer from multiple methodological limitations and a detrimental impact of APA positivity is controversial. Empirical administration of heparin or low molecular weight heparin to women with recurrent ART failures is supported by weak evidence. Importantly, thrombophilias are likely to increase thrombotic complications after ovarian stimulation for ART. CONCLUSIONS Current evidence does not support routinely testing for or treatment of thrombophilia in the setting of ART nor in couples with implantation failure. A careful personal and family history should be obtained and a risk assessment for thrombotic complications should be made in every woman undergoing ovarian stimulation. If positive, testing for thrombophilia is warranted.

Abstract
The crucial issue for a better pregnancy outcome in women with autoimmune rheumatic diseases is appropriate planning, with counseling of the ideal timing and treatment adaptation. Drugs used to treat rheumatic diseases may interfere with fertility or increase the risk of miscarriages and congenital abnormalities. MTX use post-conception is clearly linked to abortions as well as major birth defects, so it should be stopped 3months before conception. Leflunomide causes abnormalities in animals even in low doses. Although in humans, it does not seem to be as harmful as MTX, when pregnancy is detected in a patient on leflunomide, cholestyramine is given for washout. Sulfasalazine can be used safely and is an option for those patients who were on MTX or leflunomide. Azathioprine is generally the immunosuppressive of choice in many high-risk pregnancy centers because of the safety profile and its steroid-sparing property. Cyclosporine and tacrolimus can also be used as steroid-sparing agents, but experience is smaller. Although prednisone and prednisolone are inactivated in the placenta, we try to limit the dose to the minimal effective one, to prevent side effects. Antimalarials have been broadly studied and are safe during pregnancy and breastfeeding. Among biologic disease modifying anti-rheumatic agents (bDMARD), the anti-TNFs that have been used for longer are the ones with greater experience. The large monoclonal antibodies do not cross the placenta in the first trimester, and after conception, the decision to continue medication should be taken individually. The experience is larger in women with inflammatory bowel diseases, where anti-TNF is generally maintained at least until 30weeks to reduce fetal exposure. Live vaccines should not be administrated to the infant in the first 6months of life. Pregnancy data for rituximab, abatacept, anakinra, tocilizumab, ustekinumab, belimumab, and tofacitinib are limited and their use in pregnancy cannot currently be recommended.

Abstract
PURPOSE The aim of this study was to determine whether in vitro fertilization (IVF) outcomes are associated with inherited thrombophilias. METHODS Several databases including PubMed, Embase, and Cochrane Library were retrieved up to 12 January 2016. The quality of the included studies was assessed by two authors. The associations of the following mutations in inherited thrombophilias and IVF outcomes were explored: factor V Leiden (FVL), prothrombin gene G20210A mutation (PGM), 5,10-methylentetrahydrofolate reductase (MTHFR) C677T, MTHFR (A1298C) and activated protein C resistance (APCR). The main outcome measures included CPR and implantation rate (IR). The relative risk (RR) and its 95 % confidence interval (CI) were calculated for effect index. Heterogeneity test was evaluated by Chi-square based on Q statistic and I (2) statistics. RESULTS A total of seven articles published between 2007 and 2015 with the ages of subjects between 30.9 and 36.2 were included. For subgroups analysis of CPR or IR, there were no significant differences in MTHFR (C377T), MTHFR (A1298C), FVL, PGM, and FVL/PGM mutation were found between the mutation group and control group (P > 0. 05). CONCLUSIONS IVF outcomes are not associated with FVL, PGM, MTHFR (C677T), MTHFR (A1298C), and APCR mutation in inherited thrombophilias.

Abstract
Apart from its established role in the pathogenesis of venous thromboembolism (VTE), inherited thrombophilia has been proposed as a possible cause of pregnancy loss and vascular gestational complications. There is a lot of controversy in the literature on the relationship between inherited prothrombotic defects and these obstetric complications. This is a review of the literature on inherited thrombophilia and reproductive disorders. Factor V Leiden, prothrombin G20210A mutation, and protein S deficiency seem to be associated with late and recurrent early pregnancy loss, while their impact on other pregnancy complications is conflicting. No definite association has been established between protein C and antithrombin deficiency and adverse pregnancy outcome, primarily due to their low prevalence. Screening is suggested only for women with early recurrent loss or late pregnancy loss. Anticoagulant treatment during pregnancy should be considered for women with complications who were tested positive for thrombophilia.

Abstract
PURPOSE The aim of the study is to determine if thrombophilic single nucleotide polymorphisms (SNPs) affect outcomes in fresh in vitro fertilization (IVF) cycles in a large general infertility population. METHODS A prospective cohort analysis was performed at a university-affiliated private IVF center of female patients undergoing fresh non-donor IVF cycles. The effect of the following thrombophilic SNPs on IVF outcomes were explored: factor V (Leiden and H1299R), prothrombin (G20210A), factor XIII (V34L), β-fibrinogen (-455G → A), plasminogen activator inhibitor-1 (4G/5G), human platelet antigen-1 (a/b9L33P), and methylenetetrahydrofolate reductase (C677T and A1298C). The main outcome measures included positive pregnancy test, clinical pregnancy, embryo implantation, live birth, and pregnancy loss. RESULTS Patients (1717) were enrolled in the study, and a total of 4169 embryos were transferred. There were no statistically significant differences in positive pregnancy test, clinical pregnancy, embryo implantation, live birth, or pregnancy loss in the analysis of 1717 patients attempting their first cycle of IVF. Receiver operator characteristics and logistic regression analyses showed that outcomes cannot be predicted by the cumulative number of thrombophilic mutations present in the patient. CONCLUSIONS Individual and cumulative thrombophilic SNPs do not affect IVF outcomes. Therefore, initial screening for these SNPs is not indicated.

Abstract
UNLABELLED Impaired endometrial receptivity is a major cause of reproductive losses in in vitro fertilization (IVF) cycles given a normal embryo. Its causes may be associated with many diseases, including inherited thrombophilia (IT) and undifferentiated connective tissue dysplasia syndrome (uCTDS). However, endometrial receptivity remains little studied. OBJECTIVE to investigate the morphological and immunohistochemical substrates of impaired endometrial receptivity in women with uCTDS, IT, and their concurrence. SUBJECTS AND METHODS Antibodies against ER, PgR, LIF, VEGF, and PAI-1 were used to morphologically and immunohistochemically examine pipelle endometrial biopsy specimens taken from 141 women in the implantation window (on days 6-7 after ovulation). In accordance with their clinical diagnoses, the patients were divided into 4 groups: 1) 13 patients with uCTDS; 2) 100 with IT; 3) 19 with uCTDS and IT; 4) 9 healthy surrogate mothers (a control group). In the examined groups, a total of 145 (90.1%) out of all the IVF protocols were unsuccessful. In the remaining 16 (9.9%) patients without exception, miscarriage started at less than 10 weeks' gestation. RESULTS In the implantation window, the endometrium was immature in 101 (83.1%) women and corresponded to late proliferation or early secretion phases; 102 (84.3%) women were also found to have no mature pinopodes, pointing to the fact that the endometrial receptivity was very low. Immunohistochemical examination revealed the lower expression of the receptivity marker LIF in the endometrial surface epithelium and its higher expression in the stroma in the study groups (p < 0.05 for the uCTDS and uCTDS+IT groups) and the higher expression of PAI-1 and VEGF in the epithelium, stroma, and endothelium in the study groups than in the control group (p < 0.05), suggesting the intensity of neoangiogenetic processes and impaired fibrinolysis in these patients. CONCLUSION uCTDS and IT are risk factors of impaired endometrial receptivity in the pathogenesis of infertility. The manifestations of impaired endometrial receptivity in this case are a decrease in mature pinopodes in the surface epithelium; focal stromal sclerosis; and redistribution of the receptivity marker LIF from the surface epithelium to the stroma, which may be used for diagnosis, prediction, and the development of targeted therapy.

Abstract
Thrombophilic genetic factors have been shown to play an important role in implantation outcome after in vitro fertilisation (IVF). In this pilot study we investigated the frequencies of glycoprotein Ia (GpIa)-C807T and GpIIIa-PlA1/PlA2 polymorphisms in 60 nulligravidae women with a history of unexplained IVF implantation failures and compared them with 60 healthy fertile women. We found statistically significant associations between the GpIa-C807T and GpIIIa-PlA1/PlA2 polymorphisms and IVF implantation failure (odds ratio [OR] = 3.45, 95% confidence interval [CI]: 1.63-7.30, p = 0.001; and OR = 2.86, 95% CI: 1.27-6.45, p = 0.010, respectively) with the risk being higher for combined carriers of GpIa-807T and GpIIIa-PlA2 alleles (OR = 10.13, 95% CI: 2.85-35.99, p < 0.001), suggesting a synergistic effect of the two polymorphisms. The above associations were strongest for the youngest age group. Our results indicate that GpIa-807T and GpIIIa-PlA2 may be susceptibility alleles for IVF implantation failure.

Abstract
Throughout the last decade, increasing awareness has been raised on issues related to reproduction in rheumatic diseases including basic research to clarify the important role of estrogens in the etiology and pathophysiology of immune/inflammatory diseases. Sub- or infertility is a heterogeneous condition that can be related to immunological mechanisms, to pregnancy loss, to disease burden, to therapy, and to choices in regard to family size. Progress in reproductive medicine has made it possible for more patients with rheumatic disease to have children. Active disease in women with rheumatoid arthritis (RA) affects their children's birth weight and may have long-term effects on their future health status. Pregnancy complications as preeclampsia and intrauterine growth restriction are still increased in patients with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS), however, biomarkers can monitor adverse events, and several new therapies may improve outcomes. Pregnancies in women with APS remain a challenge, and better therapies for the obstetric APS are needed. New prospective studies indicate improved outcomes for pregnancies in women with rare diseases like systemic sclerosis and vasculitis. TNF inhibitors hold promise for maintaining remission in rheumatological patients and may be continued at least in the first half of pregnancy. Pre-conceptional counseling and interdisciplinary management of pregnancies are essential for ensuring optimal pregnancy outcomes.

Abstract
Abstract
Assisted reproductive technology is widely used to treat couples affected by infertility. Complications associated with assisted reproduction include venous thromboembolism, ovarian hyperstimulation syndrome, and recurrent implantation failure. It has also been proposed that thrombophilia may be associated with an increased likelihood of these events. Although data are limited, antithrombotic therapy is frequently used to enhance the likelihood of successful assisted reproduction. This chapter reviews the risks of venous and arterial thromboembolism associated with assisted reproduction, as well as available data regarding the impact of thrombophilia on the risks of thromboembolism and failure of implantation. The role of antithrombotic therapy in reducing the likelihood of these events, along with recommendations from various guidelines, are also discussed.

Abstract
BACKGROUND The usefulness of antithrombotic prophylaxis in management of Assisted Reproductive Technologies (ART) is questionable. OBJECTIVES We prospectively examined the contribution of an antithrombotic prophylaxis in influencing clinical pregnancy and live-birth in an unselected cohort of women approaching ART. PATIENTS/METHODS 1107 women with fertility problems and a valid indication for ART were recruited. Baseline and follow-up information of obstetric outcomes and antithrombotic treatment were collected. RESULTS AND CONCLUSIONS Median follow-up time was 34.5 months (range: 2-143). During the follow-up period, 595 (53.8%) women underwent ART (total 1234 cycles); 202 (33.9%) women achieved a pregnancy for a total of 255 clinical pregnancies. The concomitant use of LMWH and aspirin was significantly associated with a higher rate of clinical pregnancies (p: 0.003, OR: 4.9, 95% CI: 1.7-14.2). The pregnancy rate was also significantly increased by the use of LMWH alone (p: 0.005, OR: 2.6, 95% CI: 1.3-5.0). Carriership of inherited or acquired thrombophilia did not affect clinical outcomes of the ART. The efficacy of antithrombotic treatment was confirmed when the outcome " live-birth" was considered. Present data suggest a potential benefit of antithrombotic prophylaxis during ART in improving the number of live-births.

Abstract
Background The activation of blood coagulation could contribute to the failure of in-vitro fertilization (IVF) techniques. The aim of this study was to assess the predictive value of D-dimer levels for pregnancy outcome in women undergoing IVF. Findings A prospective study was performed in 105 women undergoing IVF. D-dimer was measured before and one week after the administration of recombinant human chorionic gonadotropin (r-hCG). The primary outcome of the study was clinical pregnancy. The mean age was 36 years (range 26 to 43 years). The main indications for IVF were infertility due to a tubaric (n = 21, 20%) or male factor (n = 37, 35%) and idiopathic infertility (n = 30, 29%) which altogether accounted for 84% of the total. Clinical pregnancy was achieved by 40/105 (38%) women of whom 32 (80%) delivered a live child. On the day of r-hCG administration, D-dimer concentrations were significantly higher in patients not achieving a clinical pregnancy (141 ng/dL vs. 115 ng/dL, p = 0.035) which remained statistically significant after correction for age and indications for IVF in multivariable analysis (p = 0.032). One week after r-hCG, the levels of D-dimer were significantly increased both in women with and without a clinical pregnancy with no differences between the groups (748 ng/dL vs. 767 ng/dL, p = 0.88). Conclusions D-dimer concentrations seem to predict a higher risk of pregnancy failure in women undergoing IVF. If confirmed in future prospective studies, D-dimer could help identifying a group of patients who could benefit from prophylaxis to increase the pregnancy success rate.

Abstract
PURPOSE In the last few years more robust evidence is emerging to point out at an increased rate of prematurity and low birth weight in singleton pregnancies following ART. Whether this increased rate is related to ART practice or to infertility per se, is still an open question. Our aim in this study was to explore this question by evaluating Protein C (ProC) Global assay in infertile women before ART treatment. METHODS A cohort of 95 unselected and consecutive infertile women, eligible for ART, was prospectively recruited for the study. The control group included 77 matched healthy fertile women with a history of spontaneous conceptions. Pro C Global assay was evaluated in both groups. A full thrombophilic work-up was performed in the study group. RESULTS ProC Global assay level was found to be significantly lower in the study as compared to the control group, corresponding to 0.78 ± 0.16 and 0.88 ± 0.16, respectively (P < 0.01). As well, abnormal ProC Global assay level of ≤ 0.8 was significantly higher in the study as compared to control group corresponding to 53 % and 29 %, respectively. ProC Global assay level was significantly lower in women within the study group found to have APCR, factor V Leiden and high factor VIII level, any thrombophilia or combined thrombophilia when compared to women without these thrombophilic risk factors. CONCLUSIONS Reduced ProC Global assay level is encountered in infertile women prior to ART treatment. This finding may suggest a unique anticoagulation Protein C pathway in infertile as compared to fertile women. Further studies are encouraged to explore this finding.

Abstract
Background: Microvascular reconstruction for oncologic defects is a challenging and rewarding endeavor, and successful outcomes are dependent on a multitude of factors. This study represents lessons learned from a personal prospective experience with 100 consecutive free flaps. Methods: All patients’ medical records were reviewed for demographics, operative notes, and complications. Results: Overall 100 flaps were performed in 84 consecutive patients for reconstruction of breast, head and neck, trunk, and extremity defects. Nineteen patients underwent free flap breast reconstruction with 10 patients undergoing bilateral reconstruction and 2 patients receiving a bipedicle flap for reconstruction of a unilateral breast defect. Sixty-five free flaps were performed in 61 patients with 3 patients receiving 2 free flaps for reconstruction of extensive head and neck defects and 1 patient who required a second flap for partial flap loss. Trunk and extremity reconstruction was less common with 2 free flaps performed in each group. Overall, 19 patients (22.6%) developed complications and 14 required a return to the operating room. There were no flap losses in this cohort. Thorough preoperative evaluation and workup, meticulous surgical technique and intraoperative planning, and diligent postoperative monitoring and prompt intervention are critical for flap success. Conclusions: As a young plastic surgeon embarking in reconstructive plastic surgery at an academic institution, the challenges and dilemmas presented in the first year of practice have been daunting but also represent opportunities for learning and improvement. Skills and knowledge acquired from time, experience, and mentors are invaluable in optimizing outcomes in microvascular free flap reconstruction.

Abstract
Implantation failure in assisted reproduction is thought to be mainly due to impaired uterine receptivity. With normal uterine anatomy, changes in endocrine profile during ovarian stimulation and medical conditions of the mother (i.e. thrombophilia and abnormal immunological response) could result in a non-receptive endometrium. High oestradiol concentrations during ovarian stimulation lead to premature progesterone elevation, causing endometrial advancement and hampering implantation, which can be overcome by a freeze-all approach and embryo transfer in natural cycles or by milder stimulation protocols. Patients with recurrent implantation failure (RIF) should be tested for inherited and acquired thrombophilias. Each patient should be individually assessed and counselled regarding therapy with low-molecular-weight heparin (LMWH). Empirical treatment with LMWH, aspirin or corticosteroids is not effective for women with RIF who have negative thrombophilic tests. If thrombophilic tests are normal, patients should be tested for immunological causes. If human leukocyte antigen dissimilarity is proven, treatment with intravenous immunoglobulin might be beneficial. Preliminary observational studies using intralipid infusion in the presence of increased natural killer cytotoxic activity are interesting but the proposed rationale is controversial and randomized controlled trials are needed. Hysteroscopy and/or endometrial scratching in the cycle preceding ovarian stimulation should become standard for patients with RIF.

Abstract
PURPOSE This study was performed to investigate the incidence of thrombophilic gene mutations in repeated assisted reproductive technology (ART) failures. METHODS The prevalence of mutated genes in the patients with a history of three or more previous ART failures was compared with the patients with a history of successful pregnancy following ARTs. The study group included 70 patients, 34 with three or more previously failed ARTs (A) and control group consisted of 36 patients with successful pregnancy following ARTs (B). All patients were tested for the presence of mutated thrombophilic genes including factor V Leiden (FVL), Methylenetetrahydrofolate reductase (MTHFR) and Prothrombin (G20210A) using real-time polymerase chain reaction (RT- PCR). RESULTS Mutation of FVL gene was detected in 5.9% women of group A (2 of 34) compared with 2.8% women (1 of 36) of control group (P = 0.6). Mutation of MTHFR gene was found in 35.3% (12 cases) as compared with 50% (18 cases) of control (35.3% versus 50%; P = 0.23). Regarding Prothrombin, only control group had 5.6% mutation (P = 0.49). No significant differences were detected in the incidences of FVL, Prothrombin and MTHFR in the study group A compared with the control group B. CONCLUSION The obtained results suggest that thrombophilia does not have a significant effect in ART failures.
