The effect of ulipristal acetate on tumor necrosis factor α, insulin-like growth factor 1, and plasminogen activator inhibitor-1 serum levels in patients with symptomatic uterine fibroids.

Introduction: Uterine fibroids (UFs) are benign tumors of the female reproductive system originating from the smooth muscle of the uterus. Currently, progesterone is known to play a key role in the differentiation of the myometrial tissue to form UFs and their abnormal growth. The mechanism of action of progesterone in UF tumorigenesis involves its effect on increasing the concentrations and dysregulation of selected growth factors. Material and methods: A retrospective cohort study was performed to evaluate and compare tumor necrosis factor α (TNF-α), insulin-like growth factor 1 (IGF-1), plasminogen activator inhibitor-1 (PAI-1) serum concentrations in patients with UFs without prior hormonal treatment, patients with UFs treated with a 3-month standard ulipristal acetate (UPA - a type of selective progesterone receptor modulator) scheme (5 mg/day) and in control patients without UFs. A total of 120 patients were divided into 3 groups (controls, UFs with UPA treatment, UFs without UPA treatment). Results: There were no significant differences in TNF-α serum concentrations between patients with UFs who underwent UPA treatment and patients who did not. Serum concentrations of IGF-1 and PAI-1 did not show significant intergroup differences. Conclusions: No significant differences were found between TNF-α concentrations in the serum of patients with UFs treated with UPA, and patients without UPA treatment. In addition, our data analysis did not show significant differences in the concentrations of IGF-1 and PAI-1 between patients with UFs and the control group. Further studies on the dependence of specific symptoms on selected growth factors are mandatory.

Can pelvic floor muscle function before surgery determine the outcome of surgical treatment of stress urinary incontinence in women?

AIM: The study aimed to determine whether pelvic floor muscle (PFM) function before surgery may correlate with the success of surgical interventions for treating stress urinary incontinence (SUI). Our hypothesis was that addressing identified variables in preoperative rehabilitation could potentially improve surgical outcomes. METHODS: This prospective observational study was conducted at a single center and enrolled women qualified to mid-urethral tape insertion for SUI between 2020 and 2022. Digital palpation and manometry (Peritron™ 9300 V) were used to evaluate PFM function. The following parameters were acquired: vaginal resting pressure, vaginal pressure during maximal voluntary contraction (MVC), the area under the curve during a 10-second MVC, moreover the ability to perform correct PFM contraction, reflexive PFM contraction during cough and relaxation were assessed. All measurements were performed before the surgical treatment and during follow-up assessments at 1, 3, and 6 months postoperatively. The primary endpoint of the study was defined as objective cure, characterized by a negative cough stress test (CST), along with a subjective assessment based on the Urogenital Distress Inventory-6 (UDI-6) and Incontinence Impact Questionnaire-7 (IIQ-7). RESULTS: The study involved 57 eligible female participants, all of whom completed the 6-month follow-up. Objective cure was observed in 75.44% of cases, while subjective cure was reported in 33%. There was no association between PFM parameters and surgical outcomes. CONCLUSION: The success of surgical treatment of SUI 6 months postsurgery is not related to preoperative pelvic floor muscle function.

Impact of preoperative pelvic floor muscle function on the success of surgical treatment of pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to identify the potential characteristics of pelvic floor muscles (PFM) in the preoperative assessment that could be associated with post-surgical prolapse severity. We hypothesized that the same variables, if identified, could be addressed in preoperative rehabilitation to improve surgical results. METHODS: This was a single-center prospective observational study that included women who underwent surgical pelvic organ prolapse repair between 2020-2022. Genital prolapse was evaluated according to the Pelvic Organ Prolapse Quantification (POP-Q) system. All the participants underwent a PFM assessment, including a vaginal digital assessment and manometry (Peritron™ 9300 V) before surgery and at 1-, 3-, and 6-month follow-ups. Several PFM variables were recorded: vaginal resting pressure, vaginal pressure during maximal voluntary contraction (MVC), area under the curve during a 10-second MVC, ability to correctly contract the PFMs, and reflexive activation during cough and relaxation. The primary endpoint of the analysis was objective surgical success defined as POP-Q 0 or 1 at the 6-month follow-up. Additionally, a change in pelvic floor muscle function was recorded during postoperative visits. RESULTS: A total of 106 females were included in the study. Fifty-one were lost during the 6-month follow-up, which is a major limitation of the study. None of the examined parameters evaluating PFM were associated with surgical success. No statistically significant difference was found in MVC and PFM endurance before and after surgery. Post-surgery, a significant change was observed in the vaginal resting pressure and the ability to correct PFM activation and relaxation. CONCLUSIONS: Preoperative PFM function is not associated with surgical success 6 months after surgery.

Quality of Life and Sexual Satisfaction in the Early Period of Motherhood-A Cross-Sectional Preliminary Study.

The aim of the study was to assess the impact of breastfeeding-related fatigue and family support on the sexuality and quality of life of mothers during early motherhood. A cross-sectional preliminary study was conducted between 1 October 2021 and 15 May 2022 in 65 women being in early postpartum period. We used the authors' questionnaire developed for the purposes of the study; the Sexual Satisfaction Scale for Women-SSS-W; the Mell-Krat scale for women; and the General Health Questionnaire-GHQ28. A significant negative correlation was found between the age of the patients and the reduction in somatic symptoms (GHQ28 questionnaire) (r = -0.315, p = 0.011). Women working professionally achieved significantly higher results in the SSS-W contentment category (r = 0.313, p = 0.014). Frequent sexual activity reduced disorders in social functioning (the GHQ28 questionnaire) (r = -0.107, p = 0.283). Women who breastfed up to 5 times a day (p = 0.033) reached significantly higher SSS-W scores in terms of communication. The partner's help significantly contributed to higher sexual satisfaction in the aspect of compatibility (p = 0.004) and the overall level of satisfaction determined with the SSS-W questionnaire (p = 0.016). The presented study suggests that older mothers who are employed and supported by a partner have a higher level of contentment, sexual satisfaction and quality of life.

Comment on 'Importance of real-time measurement of sperm head morphology in intracytoplasmic sperm injection' by Fumiaki Itoi et al.

We present a commentary on the article published in the Zygote FirstView: 'Importance of real-time measurement of sperm head morphology in intracytoplasmic sperm injection' by Fumiaki Itoi and colleagues. We comment on the importance of providing the microscope setup details whenever sperm morphology visualization is discussed. The claim of ×6000-10,000 magnification is misleading as such levels of magnification are impossible to achieve.

The Opinions of Specialists in Obstetrics and Gynecology on the Indications for Pregnancy Termination in Poland-A Preliminary Cross-Sectional Study.

The physician's decision concerning pregnancy termination is influenced by a number of factors. The study aimed at obtaining the opinions of obstetricians and gynecologists with regard to the indications for pregnancy termination, the readiness to perform the procedure personally and the assessment of the determinants thereof. The survey study was conducted between 1 January 2020 and 31 December 2021 among physicians who performed diagnostic prenatal ultrasonography. A considerable majority of physicians participating in the study did not approve of termination without medical indications (62.5%). A marked majority of them considered the following cases as indications for pregnancy termination: severe fetal defects (90%), lethal defects (91.5%) and a disease threatening maternal life (91.5%). A small group of physicians declared that they were ready to perform a termination without medical indications (12.5%). However, they were ready to perform a pregnancy termination personally in cases of threat to maternal life (77.5%), severe fetal defects (75%), lethal fetal defects (75%) and a pregnancy being a result of rape (75%). No statistical significance was observed with regard to the influence of the respondents' sex, the fact of having children or the workplace on the issue of indications for pregnancy termination. It seems justified to develop case-centered counseling concerning abortion, based on specialists in perinatology, law and ethics, especially in countries with more restrictive abortion law or strongly religious societies.

Inflammation-Related Molecules at the Maternal-Fetal Interface during Pregnancy and in Pathologically Altered Endometrium.

The blastocyst expresses paternally derived alloantigens and induces inflammation during implantation. However, it is necessary for the onset of pregnancy. An abnormal response might result in a pathological course of pregnancy or pregnancy failure. On the other hand, a state of maternal immune tolerance is necessary to ensure the normal development of pregnancy by suppressing inflammatory processes. This article discusses recognized mechanisms and the significance of inflammatory processes for embryo implantation and pregnancy establishment. We would also like to present disorders involving excessive inflammatory response and their influence on events occurring during embryo implantation. The chain of correlation between the processes responsible for embryo implantation and the subsequent physiological course of pregnancy is complicated. Many of those interrelationships are still yet to be discovered. Undoubtedly, their recognition will give hope to infertile couples for the emergence of new treatments that will increase the chance of giving birth to a healthy child.

Sacral Neuromodulation in Pregnant Women-A Case Report and Literature Review.

Millions of women around the world suffer from an overactive bladder and urinary retention. A significant number of them are of reproductive age. For 25 years, SNM has been an effective therapy for treatment-resistant hyperactive bladder and idiopathic urinary retention. The paper presents a case of a 35-year-old pregnant woman with an overactive bladder resistant to pharmacological treatment, who responded positively to sacral neuromodulation. The patient decided against deactivating the neuromodulator and, after an uneventful course of pregnancy, she gave birth by a caesarean section to a healthy female infant. The use of SNM in pregnant patients remains a constant clinical challenge. The current literature was reviewed, but published studies do not provide a clear answer. Further studies with a long follow-up period are necessary to determine more accurately the effects of SNM therapy on the fetus and the course of pregnancy. Currently, it is recommended to deactivate SNM during pregnancy. However, it seems that an individual approach to the patient with information on the risks and benefits of continuing or discontinuing therapy should be the current procedure.

Mitochondrial DNA Copy Number in Cleavage Stage Human Embryos-Impact on Infertility Outcome.

A retrospective case control study was undertaken at the molecular biology department of a private center for reproductive medicine in order to determine whether any correlation exists between mitochondrial DNA (mtDNA) content of cleavage-stage preimplantation embryos and their developmental potential. A total of 69 couples underwent IVF treatment (averaged women age: 36.5, SD 4.9) and produced a total of 314 embryos. A single blastomere was biopsied from each embryo at the cleavage stage (day-3 post-fertilization) subjected to low-pass next generation sequencing (NGS), for the purpose of detecting aneuploidy. For each sample, the number of mtDNA reads obtained after analysis using NGS was divided by the number of reads attributable to the nuclear genome. The mtDNA copy number amount was found to be higher in aneuploid embryos than in those that were euploid (mean mtDNA ratio ± SD: 6.3 ± 7.5 versus 7.1 ± 5.8, p < 0.004; U Mann−Whitney test), whereas no statistically significant differences in mtDNA content were seen in relation to embryo morphology (6.6 ± 4.8 vs. 8.5 ± 13.6, p 0.09), sex (6.6 ± 4.1 vs. 6.2 ± 6.8, p 0.16), maternal age (6.9 ± 7.8 vs. 6.7 ± 4.5, p 0.14) or its ability to implant (7.4 ± 6.6 vs. 5.1 ± 4.6, p 0.18). The mtDNA content cannot serve as a useful biomarker at this point in development. However, further studies investigating both quantitative and qualitative aspects of mtDNA are still required to fully evaluate the relationship between mitochondrial DNA and human reproduction.

Role of Leptin and Adiponectin in Endometrial Cancer.

Endometrial cancer is the most common malignancy of the female genital tract. Obesity is a strong risk factor for endometrial cancer. Adipose tissue is an active endocrine organ that synthesizes biologically active cytokine peptides, called adipokines. Adiponectin and leptin are the main cytokines of adipose tissue, which may influence the development of metabolic diseases and carcinogenesis. In this scenario, we describe the role of leptin and adiponectin in the development of endometrial cancer. A better understanding of the signalling pathway of these cytokines in endometrial cancerogenesis will provide an opportunity for effective target therapy and may be usable in fertility-sparing treatment. In the future, clinical trials focusing on adipokines, molecular biology, and genetics of the tumour will be needed.

Cross-Reactivity between Half Doses of Pfizer and AstraZeneca Vaccines-A Preliminary Study.

Media reports have caused a significant drop in confidence in the AstraZeneca ChAdOx1 nCoV-19 COVID-19 vector vaccine (Vaxzevria, AstraZeneca Södertälje, Sweden). This has caused many people, already vaccinated with the first dose of AstraZeneca, to refuse vaccination with this product. On the other hand, the increased demand for mRNA vaccines has resulted in a greater shortage of mRNA vaccines and cases of people being vaccinated with the AstraZeneca vaccine after the first dose of the Pfizer/BioNTech BNT162b2 COVID-19 vaccine (Comirnaty, Pfizer/BioNTech, Mainz, Germany). Moreover, currently, 60.9% of the global population have received at least one dose of a COVID-19 vaccine, while only 10% of people in low-income countries have received at least one dose. Even less people are fully vaccinated. The present pilot study evaluated the administration of half doses of AstraZeneca and Pfizer vaccines and included the enrollment of 26 subjects who were vaccinated with a different vaccine the first and second time. The reference group included individuals undergoing vaccination with two full doses of the Pfizer vaccine (21-day interval) monitored for their antibody levels as part of a parallel study. The distribution of antibody levels was not significantly different between those who received the Pfizer vaccine alone and those receiving the AstraZeneca vaccine plus Pfizer or Pfizer and AstraZeneca. To prepare for the next pandemic waves, solving the problem of the matching of booster vaccine to the previously received doses would be advisable. The topic is important and emerging as most of the population in low-income countries is still not vaccinated. We strongly believe that vaccine equity is the most important aspect of vaccination strategies.

IMSI-Guidelines for Sperm Quality Assessment.

Intracytoplasmic sperm injection (ICSI) is a widely used and accepted treatment of choice for oocyte fertilization. However, the quality of sperm selection depends on the accurate visualization of the morphology, which can be achieved with a high image resolution. We aim to correct the conviction, shown in a myriad of publications, that an ultra-high magnification in the range of 6000×-10,000× can be achieved with an optical microscope. The goal of observing sperm under the microscope is not to simply get a larger image, but rather to obtain more detail-therefore, we indicate that the optical system's resolution is what should be primarily considered. We provide specific microscope system setup recommendations sufficient for most clinical cases that are based on our experience showing that the optical resolution of 0.5 µm allows appropriate visualization of sperm defects. Last but not least, we suggest that mixed research results regarding the clinical value of IMSI, comparing to ICSI, can stem from a lack of standardization of microscopy techniques used for both ICSI and IMSI.

Vitamin D receptor gene polymorphisms and uterine fibroid incidence in Caucasian women.

INTRODUCTION: Uterine fibroids (UFs) are benign tumors which are derived from the smooth muscle cells of the uterus. Recent studies have demonstrated that the development of UFs can be particularly related to vitamin D and its receptor. Vitamin D comprises a group of fat-soluble steroid compounds which exert powerful, pleiotropic effects all over the human body. These actions are mediated by a specific type of receptor - vitamin D receptor (VDR). Recent findings have focused on the possible role of VDR genetic variations in the development of several types of diseases, e.g. autoimmune system diseases, various cancers and infections. MATERIAL AND METHODS: The aim of the study was to evaluate the association between rs731236, rs1544410, and rs2228570 polymorphisms in the VDR (vitamin D receptor) gene and the incidence of UFs in Caucasian women. A total of 197 patients (114 fibroid-positive and 83 controls) were included in this retrospective cohort study. VDR gene polymorphisms rs731236 (TaqI), rs1544410 (BsmI) and rs2228570 (FokI) were determined using TaqMan and Simple Probes. RESULTS: No statistically significant differences in the occurrence of selected VDR polymorphisms were observed between UF-positive women and healthy controls. CONCLUSIONS: We found no association between rs731236, rs1544410, and rs2228570 VDR polymorphisms and UF incidence in Caucasian women. Larger sample size and multi-ethnic studies are necessary to investigate the matter further.

Humoral Response after Vaccination with Half-Dose of BNT162b2 in Subjects under 55 Years of Age.

In the context of the ongoing COVID-19 pandemic, using a half-dose schedule vaccination can help to return to normalcy in a cost-efficient manner, which is especially important for low and middle-income countries. We undertook a study to confirm that in adults up to 55 years old, the humoral response to the half-dose (15 µg, 35 participants between 18 and 55 years old) and to the recommended dose (30 µg, 155 participants) in the two-dose three-week interval schedule would be comparable. Antibody levels were measured by the Elecsys Anti-SARS-CoV-2 S assay (Roche Diagnostics, upper detection limit: 2570 BAU/mL) on the day of dose 2 of the vaccine and then 8-10 days later to assess peak response to dose 2. The difference in proportions between the participants who did and did not exceed the upper detection limit 8-10 days after dose 2 was not statistically significant (p = 0.152). We suggest that a half-dose schedule can help to achieve widespread vaccination coverage more quickly and cheaply.

Abortion in Countries with Restrictive Abortion Laws-Possible Directions and Solutions from the Perspective of Poland.

The tendency towards the radicalization of abortion law is observed in numerous countries, including Poland. The aim of the present paper was to determine the main factors influencing the number of abortions performed worldwide and to indicate the main directions which should be followed to improve the patients' well-being. The authors conducted their search in the PubMed of the National Library of Medicine and Google Scholar. Databases were extensively searched for all original and review articles/book chapters in English until June 2021. The main problems associated with the contemporary policy of birth regulation include no possibility of undergoing a termination because of the conscience clause invoked by the medical personnel, restrictive abortion law and lack of sexual education. Minimal changes that should be considered are: improved sex education and the availability of contraception, free access to abortion-inducing drugs with adequate information provided by qualified medical personnel in countries with a conscience clause invoked by the personnel, and the development of an international network which would facilitate undergoing a pregnancy termination abroad to provide women with access to legal abortion assisted by professional medical personnel.

Position Statement by Experts of the Polish Menopause and Andropause Society on menopausal hormone therapy with an oral combination drug containing oestradiol 1 mg and progesterone 100 mg.

At a meeting held on 20 May 2021, reviewed the available literature on the use of the medicinal product Bijuva® for the relief of menopausal symptoms.

Humoral Response to SARS-CoV-2 Vaccine of a Patient Receiving Methotrexate Treatment and Implications for the Need of Monitoring.

We report a case of monitoring the antibody response to the BioNTech-Pfizer vaccine of a 50-year-old female diagnosed with rheumatoid arthritis undergoing treatment with methotrexate (MTX). Antibody levels were measured 21 days after dose 1 (i.e., on the day of dose 2) and then 8, 14 and 30 days after dose 2 with Elecsys Anti-SARS-CoV-2 S assay (Roche Diagnostics). Patient showed a negative result after dose 1 and had the serum sample retested using a LIAISON® SARS-CoV-2 TrimericS IgG assay (DiaSorin), which showed a positive result. Subsequent samples were tested using both assays. Antibody levels kept increasing but at a much slower rate than in patients not receiving any immunomodulatory therapies. Other research indicates that among patients with autoimmune diseases, those receiving disease-modifying antirheumatic drugs (DMARDs) have higher COVID-19 mortality than those treated with tumor necrosis factor inhibitors (TNFis). These results indicate the need for people with autoimmune diseases to be carefully observed following vaccinations, including testing of antibody levels, and treated as potentially at risk until the effect of vaccination is confirmed. The different available vaccines should also be tested to verify their usefulness in the case of people with autoimmune diseases and those who take different immunomodulatory medications.

Cervicovaginal Microbiome after Cervical Intraepithelial Neoplasia Treatment. A Protocol for Systematic Review and Meta-Analysis.

(1) Background: The microbiome consists of microorganisms from various kingdoms with numerous physical and chemical properties Lactobacillus species constitute the highest percentage of healthy cervical and vaginal microbiota. Dysbiosis may cause adverse outcomes, e.g., bacterial vaginosis, pelvic inflammatory disease and pregnancy complications. The cervicovaginal microbiome might contribute to the development of a persistent HPV infection-the main risk factor of cervical cancer-and influence progression to malignancy The aim is to perform a systematic review of current literature and a meta-analysis regarding microbiome changes after cervical intraepithelial neoplasia treatment. (2) Methods: We will search PubMed, Scopus, Google Scholar and Embase Database and trace citations in the reference sections. Randomized and non-randomized controlled studies, case-control and cohort studies published between January 2000 and May 2021 will be included in the study protocol. The following keywords will be used: 'microbiome', 'vaginal microbiome', 'cervical microbiome', 'cervical neoplasia treatment', 'conization', 'electroconization', and 'electrosurgical treatment'. Statistical analyses will be performed using RevMan 5.4. (3) Results: The results will be published as a peer-reviewed article. (4) Conclusions: The study will show which forms of intraepithelial neoplasia treatment change the cervicovaginal microbiome. Finding the best form of treatment by studying the cervicovaginal microbiome after various forms of treatment is essential. Patients would benefit not only from the treatment of the initial disease but also the management of dysbiosis, which might underlie other pathologies.

Usefulness of IVD Kits for the Assessment of SARS-CoV-2 Antibodies to Evaluate the Humoral Response to Vaccination.

BACKGROUND: The introduction of the vaccination against SARS-CoV-2 infection creates the need for precise tools for the quality control of vaccination procedures, detection of poor humoral response, and estimation of the achieved protection against the disease. Thus, the study aimed to compare the results of the anti-SARS-CoV-2 tests to evaluate the application of the WHO standard unitage (the binding antibody units; BAU/mL) for a measurement of response to the vaccination. METHODS: Patients undergoing vaccination against SARS-CoV-2 with Pfizer/BioNTech BNT162b2 (BNT162b2) (n = 79), referred for SARS-CoV-2 antibody measurement prior to vaccination and 21 days after dose 1, and 8, 14, and 30 days after dose 2 were included. The sera were tested with three assays: Elecsys SARS-CoV-2 S (Roche), LIAISON® SARS-CoV-2 TrimericS IgG (DiaSorin), and SARS-CoV-2 IgG II Quant (Abbott). RESULTS: The three assays showed varying correlations at different time points in the study. The overall agreement for all samples was moderate to high (ρ = 0.663-0.902). We observed the most uniform agreement for the day of dose 2 (ρ = 0.775-0.825), while it was least consistent for day 8 (ρ = -0.131-0.693) and 14 (ρ = -0.247-0.603) after dose 2. The dynamics of changes of the SARS-CoV-2 antibody levels in patients without history of prior SARS-CoV-2 infection appears homogenous based on the Roche results, more heterogenous when considering the DiaSorin results, and in between for the Abbott results. CONCLUSIONS: The results highlight the need for further work on the international standard of measurement of SARS-CoV-2 Ig, especially in the era of vaccination. The serological assays can be useful to detect IgG/IgM antibodies to assess the response to the vaccination. However, they cannot be used interchangeably. In terms of the evaluation of the immune response to the BNT162b2 vaccine, Roche and Abbott kits appear to be more useful.

The role of vitamin D in perinatology. An up-to-date review.

The role of vitamin D in perinatology is a subject of major interest in current medicine. There is growing evidence about the role of maternal vitamin D levels in pregnancy outcomes. The aim of this review is to summarize the current literature about the role of vitamin D in perinatology. Evidence from this review suggests associations between low levels of maternal vitamin D and higher risk of certain obstetrical complications. Vitamin D has been found to be related to preeclampsia, gestational diabetes mellitus, low birth weight, and preterm birth. The current literature supports vitamin D supplementation in pregnant women, but more high-quality data are necessary. The problem that remains is how to achieve an optimal 25-hydroxyvitamin D level. To determine the real benefits of vitamin D supplementation in pregnancy, we need high-quality trials in larger groups.
