Surface Immune Checkpoints as Potential Biomarkers in Physiological Pregnancy and Recurrent Pregnancy Loss.

Due to the genetic diversity between the mother and the fetus, heightened control over the immune system during pregnancy is crucial. Immunological parameters determined by clinicians in women with idiopathic recurrent spontaneous abortion (RSA) include the quantity and activity of Natural Killer (NK) and Natural Killer T (NKT) cells, the quantity of regulatory T lymphocytes, and the ratio of pro-inflammatory cytokines, which indicate imbalances in Th1 and Th2 cell response. The processes are controlled by immune checkpoint proteins (ICPs) expressed on the surface of immune cells. We aim to investigate differences in the expression of ICPs on T cells, T regulatory lymphocytes, NK cells, and NKT cells in peripheral blood samples collected from RSA women, pregnant women, and healthy multiparous women. We aim to discover new insights into the role of ICPs involved in recurrent pregnancy loss. Peripheral blood mononuclear cells (PBMCs) were isolated by gradient centrifugation from blood samples obtained from 10 multiparous women, 20 pregnant women (11-14th week of pregnancy), and 20 RSA women, at maximum of 72 h after miscarriage. The PBMCs were stained for flow cytometry analysis. Standard flow cytometry immunophenotyping of PBMCs was performed using antibodies against classical lymphocyte markers, including CD3, CD4, CD8, CD56, CD25, and CD127. Additionally, ICPs were investigated using antibodies against Programmed Death Protein-1 (PD-1, CD279), T cell immunoglobulin and mucin domain-containing protein 3 (TIM-3, CD366), V-domain Ig suppressor of T cell activation (VISTA), T cell immunoglobulin and ITIM domain (TIGIT), and Lymphocyte activation gene 3 (LAG-3). We observed differences in the surface expression of ICPs in the analyzed subpopulations of lymphocytes between early pregnancy and RSA, after miscarriage, and in women. We noted diminished expression of PD-1 on T lymphocytes (p = 0.0046), T helper cells (CD3CD4 positive cells, p = 0.0165), T cytotoxic cells (CD3CD8 positive cells, p = 0.0046), T regulatory lymphocytes (CD3CD4CD25CD127 low positive cells, p = 0.0106), and NKT cells (CD3CD56/CD16 positive cells, p = 0.0438), as well as LAG-3 on lymphocytes T (p = 0.0225) T helper, p = 0.0426), T cytotoxic cells (p = 0.0458) and Treg (p = 0.0293), and cells from RSA women. Impaired expression of TIM-3 (p = 0.0226) and VISTA (p = 0.0039) on CD8 cytotoxic T and NK (TIM3 p = 0.0482; VISTA p = 0.0118) cells was shown, with an accompanying increased expression of TIGIT (p = 0.0211) on NKT cells. The changes in the expression of surface immune checkpoints indicate their involvement in the regulation of pregnancy. The data might be utilized to develop specific therapies for RSA women based on the modulation of ICP expression.

The effect of high-intensity focused ultrasound guided by magnetic resonance therapy on obstetrical outcomes in patients with uterine fibroids - experiences from the main Polish center and a review of current data.

Introduction: Uterine fibroids (UFs) are benign tumors of female genital tract. Clinically symptomatic UFs may be a cause of serious health problems for many women worldwide. The optimal choice of a treatment method should fit a patient's specific life situation or expectancies (especially fertility) as much as possible. In line with the general current trend in medicine and surgery, great importance is attached to the development of minimally invasive radiological procedures e.g., magnetic resonance guided focused ultrasound (MRgFUS). Materials and methods: Single-center retrospective cohort study conducted at the Department of Obstetrics and Gynecology of Pro-Familia Hospital in Rzeszów, Poland. The study group consisted of 276 patients suffering from UFs and treated with MR-HIFU over the period from April 2015 to May 2018. Results: In our group 20 out of 276 patients conceived after the MR-HIFU therapy (7.25%). A general improvement and alleviation of symptoms of the disease after MRgFUS/MR-HIFU procedure were observed in 80% (n = 16) of study participants that conceived. 15% (n = 3) did not report any changes in disease severity. Out of 11 patients who already gave birth - 63.64% (n = 7) underwent cesarean section. Conclusions: MRgFUS/MR-HIFU seems to be an interesting minimally invasive alternative for women with UFs who wish to conceive and deliver after the procedure. This method does not increase the rate of spontaneous abortions or pregnancy complications. In our opinion, it is important to take off an unjustified badge stating that MRgFUS/MR-HIFU method is contraindicated in women with UFs who wish to conceive.

Treatment of genitourinary syndrome of menopause: the potential effects of intravaginal ultralow-concentration oestriol and intravaginal dehydroepiandrosterone on quality of life and sexual function.

The climacteric is considered a natural phase in a woman's aging process and is defined as the period starting from the decline in ovarian activity until after the end of ovarian function. Genitourinary syndrome of menopause (GSM) is commonly observed in menopausal women and is characterised by a collection of symptoms resulting from changes to the internal and external genitalia as well as the lower urinary tract. Several studies have demonstrated the close association between sexual dysfunction and symptoms related to GSM. Many medications, at different doses, have been studied over the years for the treatment of the symptoms of GSM. More specifically, ultralow-dose intravaginal oestriol and intravaginal dehydroepiandrosterone (DHEA) are reported to improve symptoms, signs, and quality of life of women with GSM, and they are safe owing to their specific local effect. While the dosage and the administration of intravaginal DHEA are well defined, the literature on intravaginal oestriol is less uniform: different doses and times of administration are proposed with different possible combinations with other non-pharmacological therapies, although a more standardised treatment may be necessary. The aim of this review is to summarise the available data about the effects of ultralow-concentration oestriol and intravaginal DHEA on the menopause-related symptoms, quality of life, and sexual function of women affected by GSM.

A comparison of sacral neuromodulation vs. transvaginal electrical stimulation for the treatment of refractory overactive bladder: the impact on quality of life, body image, sexual function, and emotional well-being.

Overactive bladder syndrome (OAB) is defined by the presence of urinary urgency, with or without urge incontinence, usually accompanied by an increase in urinary frequency and nocturia in the absence of urinary tract infections (UTI) or other diseases. The overall prevalence of OAB symptoms in the female population is reported to be 16.6% and increases with advancing age and menopause. The aetiology of OAB is not fully understood and is likely to affect a heterogeneous population of patients due to changes to their central and peripheral nervous systems. Although OAB is frequently associated with female sexual dysfunction (FSD), its real impact on sexual function in women has been evaluated only in a few studies. The first line of treatment for OAB includes behavioural modification and physical therapy, either as monotherapies or in combination. Many patients who have not had success in managing their symptoms with more conservative therapies may decide to resort to third-line treatments for refractory OAB. These treatments include neuromodulation therapies, particularly transvaginal electrical stimulation (TES) and sacral neuromodulation (SN). The aim of this short commentary is to provide an overview of the effectiveness of these treatments and of their impact on quality of life, body image, sexual function, and emotional well-being.
