After adjusting for paternal and maternal confounders, paternal blood concentrations of Cd [-0.30(-0.11,-0.02)], As [-0.26(-0.16,-0.11)], and U [-0.22(-0.24,-0.02)] were inversely associated with embryo cell cleavage on day 3. Counterintuitively, paternal blood and semen Pb levels [0.26(0.01,0.22); 0.25(0.03,0.14)] as well as semen U levels [0.27(0.01,0.19)] were positively associated with the proportion of implanted embryos. There were no significant associations observed for clinical pregnancy and live birth rates with any paternal heavy metal concentrations in semen and blood. These findings highlight the importance of paternal health for embryo efficiency outcomes in ICSI treatment cycles and the need for more male partner inclusive counseling in fertility practice. They also underline a paradoxical positive association between some heavy metal pollutants at low exposure levels and reproductive outcomes.Injection of intraovarian platelet-rich plasma (PRP) was recently presented in terms of improvement ovarian function in women with a poor ovarian response (POR) or primary ovarian insufficiency (POI). In a before and after study, 17 poor responder women and 9 women with the diagnosis of POI were recruited. The multifocal intramedullary infusion of 1.5 ml activated PRP was performed into each ovary. The majority of women in both groups received the second PRP injection with the twofold increase in the dosage to 3ml, 3 months after the first injection. Evaluation of serum anti-mullerian hormone ( AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) was performed. In addition, all women were followed with regard to pregnancy outcome up to delivery. In the POI group, menstrual restoration was monitored. The significant difference was not detected regarding the hormonal profile between the three time points in both groups. With regard to pregnancy outcome, 8/17 (47%) of PORs had spontaneous pregnancy in response to PRP injection. Of those, three women (37.55%) had abortions, whereas 4 pregnancies (50%) led to healthy live births, and one woman (12.5%) was in the 24th week of her pregnancy. Menstruation recovery occurred among 22.2% of women with POI after the second PRP injection, but no one became pregnant. Intraovarian injection of autologous PRP might be considered an alternative treatment in poor responders. As for women with POI, it is questionable whether PRP could induce menstrual recovery.Adenomyosis is associated with dysmenorrhea, infertility, and lesional fibrosis. The pathogenesis of adenomyosis is still unclear. Plasminogen activator inhibitor 1 (PAI-1) plays important roles in pathological activities like tumor metastasis and endometriosis. Our objective was to investigate the expression and localization of PAI-1 in eutopic and ectopic endometrium with adenomyosis and in endometrium without adenomyosis. We also sought to determine the relationship between PAI-1 immunoreactivity and the severity of dysmenorrhea and the extent of lesional fibrosis in adenomyosis. check details PAI-1 expression was significantly higher in the ectopic endometrium of patients with adenomyosis than in both the eutopic endometrium of patients with adenomyosis and the endometrium of controls. Ectopic PAI-1 expression correlated positively with dysmenorrhea visual analog scale (VAS) scores and the extent of lesional fibrosis in adenomyosis. High PAI-1 expression increased the likelihood of moderate to severe dysmenorrhea in adenomyosis. These results suggest that PAI-1 is involved in the adenomyosis-associated dysmenorrhea and lesional fibrosis, which provide a potential target in treating symptomatic adenomyosis.The cell division cycle 20 (CDC20) protein is a co-activator of anaphase-promoting complex/cyclosome (APC/C), required for mitotic exit and also meiotic exit, containing seven WD40 repeats in the C-terminus responsible for protein-protein interactions. Recently, a previous study has shown that biallelic mutations in CDC20 are causative for female infertility with abnormalities in oocyte maturation and embryonic development. This study is to further identify new mutations of CDC20 and the prevalence of variants in our cohort. A cohort of 50 primary infertile females with oocyte maturation abnormality and early embryonic arrest were recruited. Genomic DNA was isolated from peripheral blood samples. Mutation screening of all the coding regions of CDC20 was performed by Sanger sequencing. The pathogenicity of the identified variants on the CDC20 protein was accessed in silico. Two CDC20 variants, a nonsense mutation p.R262* and a missense mutation p.A211T, identified in one female of 50 unrelated affected individuals, accounting for a relative small proportion of this cohort (2%). In silico analysis revealed that the p.R262* would cause no production of protein or a truncated protein lacking five WD40 repeats in the C-terminus; and that p.A211T may interfere with the formation of a deep hydrophobic pocket and thus disturb the binding of CDC20 protein to the substrates of APC/C. This study identified two novel mutations in CDC20, further expanding the mutation spectrum of this gene. Our findings further confirm that biallelic mutations in CDC20 occur in a proportion of infertile females with oocyte maturation abnormality and early embryonic arrest.

Current guidelines on coronary anomalies are primarily based on expert consensus and alimited number of trials. Agold standard for diagnosis and aconsensus on the treatment strategy in this patient group are lacking, especially for patients with an anomalous origin of acoronary artery from the opposite sinus of Valsalva (ACAOS) with an interarterial course.

To provide evidence-substantiated recommendations for diagnostic work-up, treatment and follow-up of patients with anomalous coronary arteries.

Aclinical care pathway for patients with ACAOS was established by six Dutch centres. Prospectively included patients undergo work-up according to protocol using computed tomography (CT) angiography, ischaemia detection, echocardiography and coronary angiography with intracoronary measurements to assess anatomical and physiological characteristics of the ACAOS. Surgical and functional follow-up results are evaluated by CT angiography, ischaemia detection and aquality-of-life questionnaire. Patient inclusion for the first multicentre study on coronary anomalies in the Netherlands started in 2020 and will continue for at least 3years with aminimum of 2years of follow-up.
