CP violation in K±→π0π0π±K^{\pm}\to\pi^0\pi^0\pi^{\pm} decay

CP violation leads to a difference between the parameters $g^+$ and $g^-$ describing the energy distributions of the charged pions produced in the $K^+ \to\pi^0 \pi^0 \pi^+$ and $K^- \to \pi^0\pi^0 \pi^-$ decays. We study the difference $(g^+ - g^-)$ as a function of the relative contributions from the QCD-penguin and the electroweak-penguin diagrams. We find that the combination of these contributions in $(g^+ - g^-)$ is very similar to the corresponding one defining the parameter $\epsilon'$ in the $K_L \to 2\pi$ decays. This observation allows a determination of the value of $(g^+ - g^-)$, using data on $\epsilon'$

Options for overcoming implantation failures in infertility of uterine genesis due to chronic endometritis. A review

Chronic endometritis remains one of the most controversial issues of modern gynecology. The high relevance of research in this area is confirmed not only by the high prevalence but also by the extremely negative impact of this disease on the reproductive potential of patients. The complexity of the pathogenesis mechanism of the chronic inflammatory process of the endometrium stimulates the genuine interest of the world gynecological community to study the main patterns of endometrial receptor disorder, including implantation status and repeated reproductive failures. In this regard, it is essential to summarize the accumulated results of worldwide research to find the most optimal and effective diagnostic and therapeutic approaches

Vulvovaginal atrophy in the peri- and post-menopause: relevance and impact on quality of life

Vulvovaginal atrophy (VVA) is detected in more than 50% of postmenopausal women, and at 4049 years of age, 15-19% of women have relevant signs. Atrophic changes in the female urogenital system are associated with hypoestrogenism, which results in the defective synthesis of collagen and elastin due to reduced functional activity of fibroblasts. Although the symptoms of genitourinary syndrome of menopause significantly impair the quality of life, women rarely seek medical help for urogenital symptoms, considering them a normal condition for the period of aging. We searched Cochrane Library, PubMed, Science Direct, and ELibrary databases for the keywords vulvovaginal atrophy, genitourinary syndrome of menopause, quality of life, epidemiology, and postmenopausal age for 20122022. The literature review suggests that the prevalence of VVA is extremely high but underestimated due to the infrequent seeking of medical care by female patients with relevant symptoms. The genitourinary syndrome of menopause dramatically impacts patients' quality of life, but not all women eligible for treatment receive it. One of the reasons for refusing hormonal treatment is patients' fear of the systemic effects of hormonal drugs. There is an unmet need for alternative non-hormonal therapies. The objective is to analyze and systematize the scientific data accumulated over the past ten years on the epidemiology of VVA, its impact on patients' quality of life, and the challenges in diagnosing and treating the disease

Efficacy of laser remodeling in the genitourinary syndrome of menopause: A review

The real-world treatment of genitourinary syndrome of menopause has several limitations: contraindications to topical estrogen therapy, which is currently recognized as the "gold standard" treatment for vulvovaginal atrophy (VVA), fear of the systemic effects of topical estrogens or/and carcinophobia, and poor compliance of patients to intravaginal agents. Therefore, there is an unmet need for alternative noninvasive or minimally invasive therapies, mostly non-hormonal. A PubMed, Cochrane Library, Science Direct, and ELibrary databases were searched for the keywords CO2-laser, Er:YAG-laser, vulvovaginal atrophy, genitourinary syndrome of menopause, treatment, postmenopausal age for 20122022. Remodeling microablative laser therapy using carbon dioxide (CO2) is a promising method for treating VVA, acting pathogenetically and symptomatically. CO2 laser relieves VVA symptoms and improves the condition of the vaginal mucosa by enhancing regeneration and restoring vaginal pH. However, evidence of the efficacy and long-term safety of the method, obtained in high-quality studies, is needed before the method can be introduced into widespread clinical practice. Aim. To analyze and summarize the evidence-based and experimental data on the efficacy and safety of laser therapy for VVA and genitourinary syndrome of menopause

Metabesity: pathogenetic bases and predictive capabilities. A review

One of the most pressing problems of our time is obesity, recognized by the WHO as a pandemic of the XXI century. It is important to remember that obesity is a full-fledged nosological entity, but many women think that obesity is just a problem of beauty and aesthetics. It is important to note that this nosology has a number of serious consequences, starting with the development of cardiovascular disease and ending with cancer. However, the “problem in the problem” is the so-called “metabesity” – a new term that reflects a number of diseases, the pathogenesis of which is based on the metabolic syndrome. Obesity, metabolic syndrome and metabesity seem to be different concepts, but the absolute identity of the pathogenetic basis characterizes them as successive stages of one global process. In this regard, it is necessary to highlight the key mechanisms of the development of the described disorders and to consider the concept of clinical management of patients in this cohort
