Background : Vulvovaginal atrophy (VVA) significantly impacts the quality of life in breast cancer patients leading to symptoms like vaginal dryness, dyspareunia, and genital discomfort. Quality of life in this context is measured using validated scales like the Vaginal Health Index, Visual Analog Scale (VAS), and the Female Sexual Function Index (FSFI). Methods : We performed a systematic review and meta-analysis to identify effective treatment options for VVA, including topical estrogen, systemic hormone therapy, vaginal DHEA, ospemifene, and non-hormonal methods like intravaginal laser therapy, moisturizers, and lubricants. A systematic search of four databases (MEDLINE, Scopus, CENTRAL, Embase) identified studies on VVA treatment efficacy in breast cancer patients, yielding 13,039 records, with 32 eligible studies and 8 included in the meta-analysis. Results : Significant improvements were found with intravaginal laser therapy, showing notable differences in the Vaginal Health Index (MD = 8.24, p < 0.01), dyspareunia (MD = -4.82, p = 0.05), and dryness (MD = -5.05, p = 0.01). However, no significant changes were observed in FSFI and vaginal pH. Notably only intravaginal laser therapy was included in the meta-analysis, as other treatment options lacked comparable data. Both hormonal and non-hormonal treatments improved quality of life, with laser therapy showing the most substantial effects. Conclusions : Intravaginal laser therapy is an effective treatment for VVA symptoms in breast cancer survivors, particularly in improving the Vaginal Health Index and reducing dyspareunia. Despite the strengths of the study, variability among studies, lack of RCT-s and data limitations, especially on long-term effects, present challenges.

Introduction: The lifetime prevalence of human papillomavirus infection (HPV) is estimated to be around 80% and it is the most common sexually transmitted infection. Despite being well known for its oncologic relevance, it has been associated with adverse pregnancy outcomes, though available evidence is contradicting. Previous meta-analyses involved articles which based HPV infection on Pap smear results, leading to a significant source of bias. Therefore, we aimed to assess the burden of genetically proven HPV infection on adverse pregnancy outcomes., Material and Methods: In our meta-analysis, pregnant women tested for HPV DNA were only considered eligible. We conducted a systematic search in three major databases (PubMed, Embase, and CENTRAL) on September 22, 2023. Cohort, cross-sectional, and case-control studies were eligible for the analysis. The exposed group consisted of HPV-infected patients. We assessed the odds ratios (OR) with a confidence interval (CI) of 95%. In order to reduce the heterogeneity, we performed subgroup analyses based on different strains (high risk HPV, HPV 16/18, study design). The study was prospectively registered on PROSPERO (CRD42022370228)., Results: Our study involved 14 articles with 7008 women. A significant association was found between preterm delivery and HPV infection (OR: 1.94, CI: 1.31-2.87). No significant association was found when separately examining high-risk HPV-infected women (OR: 1.94, CI: 0.82-4.59), and HPV 16 or 18-infected women (OR: 2.08, CI: 0.50-8.63) in terms of preterm delivery. No significant association was found between spontaneous abortion and HPV infection (OR: 1.02, CI: 0.16-6.31)., Conclusions: Our analysis indicates an association between HPV infection and preterm delivery. It is imperative that future studies consider confounding variables more comprehensively. Additionally, the global implementation of HPV vaccination programs holds significance not only in oncology but also in obstetrics., (© 2024 The Author(s).

Objectives: This systematic review aimed to evaluate current surgical and non-surgical management strategies for malignant bowel obstruction (MBO) in patients with gynaecological cancer. Methods: Comprehensive literature searches were conducted across MEDLINE, Embase, CENTRAL, and Scopus, without restrictions on language or publication date. Following the removal of duplicates, 4866 articles were screened, with 34 meeting the inclusion criteria. Results: Surgical intervention remains the definitive treatment for MBO, offering longer symptom-free periods and improved survival, particularly when conservative methods fail. However, the selection of surgical candidates is crucial due to the high risk of morbidity and the potential for significant complications. Non-surgical treatments, such as the use of Gastrografin, Octreotide, and Dexamethasone, along with invasive procedures like nasogastric tubing, percutaneous gastrostomy, and stent placement, offer varying degrees of symptom relief and are often considered when surgery is not feasible. Conclusions: In this article we provide a potential therapeutic algorithm for the management of patients with MBO. This review underscores the urgent need for high-quality research to develop clear, evidence-based guidelines for MBO management in patients with gynaecologic cancer. Establishing standardised protocols will improve patient outcomes by aiding clinicians in making informed, individualised treatment decisions.

Endometrial cancer is a leading gynecological malignancy, with obesity being a significant risk factor due to increased estrogen production in body fat. Current treatments often involve hysterectomy, which precludes fertility, thus highlighting the need for fertility-preserving options. This study aims to evaluate the combined efficacy of a levonorgestrel intrauterine device (LNG-IUD), metformin, and liraglutide for treating women with endometrial hyperplasia or early stage endometrial cancer while preserving fertility. The study will enroll 264 women aged 18-45 with a BMI > 30 who desire uterine preservation. Participants will be randomized into three groups: LNG-IUD alone, LNG-IUD plus metformin, and LNG-IUD plus metformin and liraglutide. Primary outcomes will include complete pathological remission, while secondary outcomes will assess histological changes, glucose, insulin levels, and weight changes over a 12-month period. This study protocol hypothesizes that LNG-IUD combined with metformin and liraglutide may potentially lead to higher regression rates of endometrial hyperplasia (EH) and early stage endometrial cancer (EC) compared to LNG-IUD alone. Furthermore, the protocol anticipates that these combination therapies will demonstrate good tolerability with minimal adverse effects, suggesting the potential benefit of integrating metabolic interventions with LNG-IUD to enhance treatment efficacy while preserving fertility in women with EH and EC.

Introduction: The incidence of infertility caused by diminished ovarian reserve has become a significant problem worldwide. The beneficial effect of PRP treatment of the ovaries has already been described, but the high-level evidence of its effectiveness has not yet been proven., Materials and Methods: A systematic search was performed in five databases, until March 12th, 2024. Both randomized and non-randomized studies that compared PRP treatment of the ovaries to self-control among women with diminished ovarian reserve were eligible for inclusion. Hormonal levels (Anti-Müllerian hormone (AMH), Follicle stimulating hormone (FSH), Luteinizing hormone (LH), Estradiol (E2), In-vitro fertilization parameters (Antral follicle count, oocyte, and embryo count), biochemical and spontaneous pregnancy and livebirth were measured., Results: 38 eligible studies were identified reporting on 2256 women. The level of AMH rised, the level of FSH decreased significantly after the PRP treatment. AMH 1 month MD 0.20 (n = 856, p > 0.001, 95% CI: [0.12;0.28]), 2 months MD 0.26 (n = 910, p = 0.013, 95% CI: [0.07;0.44]), 3 months MD 0.36 (n = 881, p = 0.002,95% CI: [0.20;0.52]). FSH 1 month MD -10.20 (n = 796, p > 0.039, 95% CI: [-19.80;-0.61]), 2 months MD -7.02 (n = 910, p = 0.017, 95% CI: [-12.48; -1.57]), 3 months MD -8.87 (n = 809, p = 0.010, 95% CI: [-14.19; -3.55]). The antral follicle count elevated significantly MD 1.60 (n = 1418, p =  < 0.001, 95% CI: [0.92; 2.27]). Significant improvement was observed in the number of retrieved oocytes MD 0.81 (n = 802, p = 0.002, 95% CI: [0.36; 1.26]), and embryos created MD 0.91 (n = 616, p = 0.001, 95% CI: [0.45;1.36]). The incidence of spontaneous pregnancy following PRP treatment showed a rate with a proportion of 0.07 (n = 1370, 95% CI: 0.04-0.12), the rate of biochemical pregnancy was 0.18 (n = 1800, 95% CI: 0.15-0.22), livebirth was 0.11 (n = 1482, 95% CI: 0.07-0.15)., Conclusions: Our meta-analysis showed that based on protocolized analysis of the widest scientific literature search to date, containing predominantly observational studies, PRP treatment resulted in a statistically significant improvement in the main fertility parameters of diminished ovarian reserve women. Further multicenter, randomized trials, with large patient numbers and a longer follow-up period are needed to certify our results and develop the most effective treatment protocol., (© 2024.

Background : Lifestyle factors significantly impact overall health. Our aim was to assess reproductive health awareness among patients who applied for emergency contraceptive pills. Methods : This present retrospective observational study between July 2021 and September 2021 is embedded in the MEEC (Motivation and Epidemiology of Emergency Contraceptive Pill) based on the study cohort of a Hungarian data bank containing follow-up data of 447 women who applied for EC telemedicine consultation. Collected data: age, history of previous pregnancy, lifestyle factors like smoking, alcohol consumption, sexual characteristics: partner consistency and protection during intercourse, cervical cancer screening within the past 2 years, previous HPV screening, and the preference for future contraceptive methods. The investigation also compiled accurate data on intercourse (elapsed time to request a medical consultation). Lifestyle factors were scored. Results : The more health-conscious patients were quicker to report for a post-event pill. Earlier pregnancies and older age were associated with greater reproductive health awareness. Conclusions : Reproductive health awareness is increased by previous pregnancies and older age. More health-conscious women consult a doctor earlier, which can reduce the chance of various health damage. Our study emphasizes the significance of lifestyle factor influence on reproductive health decisions.

Background: Delivering contraceptive hormones through a transdermal patch or a vaginal ring might have advantages over the traditional oral route., Objectives: To compare the effectiveness, compliance, and side effect profile of oral and parenteral drug administration methods., Methods: We performed a systematic literature search in four medical databases-MEDLINE (via PubMed), Cochrane Library (CENTRAL), Embase, and Scopus-from inception to 20 November 2022. Randomized controlled trials assessing the efficacy, compliance, and adverse event profile of combined parenteral and oral hormonal contraceptives were included., Results: Our systematic search provided 3952 records; after duplicate removal, we screened 2707 duplicate-free records. A total of 13 eligible studies were identified after title, abstract, and full-text selection. We observed no significant difference in contraceptive efficacy (Pearl Index) between oral and parenteral drug administration (MD = -0.06, CI: -0.66-0.53; I 2 = 0%). We found significant subgroup differences between parenteral methods in terms of compliance (χ 2 = 4.32, p =0.038, I 2 = 80%) and certain adverse events: breast discomfort (χ 2 = 19.04, p =0.001, I 2 = 80%), nausea (χ 2 = 8.04, p =0.005, I 2 = 75%), and vomiting (χ 2 = 9.30, p =0.002; I 2 = 72%)., Conclusion: Both parenteral and oral contraceptives can be used as an effective contraceptive method, and the route of administration should be tailored to patient needs and adverse event occurrence.

Objectives: Little is known about the motivations to apply for emergency contraception (EC). Our first aim was to explore the motivating circumstances to use EC as fast as possible. Our second aim was to explore the contraceptive method of the population seeking EC., Study Design: This present retrospective observational study between July 2021 and September 2021 is embedded in the MEEC (Motivation and Epidemiology of Emergency Contraceptive Pill) based on the study cohort of a Hungarian data bank containing follow-up data of 455 women applied for EC telemedicine consultation. Variables assessed were: age, gynecological history (pregnancies, abortions, miscarriages), data of the intercourse (elapsed time, contraceptive method), and data of the menstrual cycle, and relationship status., Results: Of all patients, 59.3 % reported condom rupture, 29.5 % no protection, and 11.2 % other. Patients using condom applied for EC significantly sooner than those using no protection and using other protective methods. A significantly shorter elapsed time was observed in patients with a history of a previous pregnancy. No significant relationship was seen between the way of protection, previous pregnancies, and surprisingly the time of ovulation despite the obvious intention of avoiding pregnancy., Conclusions: This is the first study to examine the potential role of epidemiologic factors as motivators for EC on the basis of a large patient cohort. Our study demonstrates the significant role of condom rupture/use and the history of previous pregnancies to be the strongest motivators for EC., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.

Introduction: Emergency contraception is an effective and safe solution for preventing unwanted pregnancies. Many methods of emergency contraception are used, which have different mechanisms of action and time frames., Objective: Providing information to healthcare professionals and decision-makers based on the literature data about the target populations of emergency contraception, evidence-based modern methods, their effectiveness, and practical application for the purpose of reducing the incidence of unintended pregnancies., Methods: We conducted a systematic literature search in MEDLINE (PubMed), Embase and Scopus databases based on relevant keywords, for publications that were published between 1960 and 2023., Results: 23 clinical professional publications were selected that examined the effectiveness of oral and long-term usable contraceptives as emergency contraceptives. Our research results were interpreted in terms of weight, breastfeeding, time elapsed since the intercourse and future contraceptive plans, which help to select the most appropriate emergency contraceptive for healthcare professionals., Conclusion: Based on the literature data, our systematic review provides assistance for choosing between the available oral levonorgestrel, ulipristal acetate, and intrauterine contraceptive devices available in Hungary based on effectiveness, target population, and accessibility. We support the healthcare governance in creating up-to-date professional guidelines to improve the availability of emergency contraception and, consequently, enhance reproductive health.

Uterine rupture is a rare complication during pregnancy which may even lead to the death of the mother and the fetus. In this report, the management of a herniated amniotic sac associated with uterine dehiscence is presented. A 25-year-old primigravida at 30 weeks with a history of a previous unilateral salpingectomy was transferred to our hospital with the potential diagnosis of a herniated amniotic sac, which was discovered during a routine ultrasound scan. The patient had no prior complaints or any other signs that would have indicated a serious condition during her pregnancy. She underwent an emergency cesarean section and a two-layer closure of the lesion. An adequate suture during laparoscopic salpingectomy provides prevention of uterine rupture during subsequent pregnancies. A medical history with a previous laparoscopic dehiscence should necessitate a more frequent sonographic observation during pregnancy. Orv Hetil. 2023; 164(25): 988-992.

Blood flow increases in arteries of the skeletal muscles involved in active work. Our aim was to investigate the gender differences as a result of adaptation to sport in the femoral arteries. Vascular reactivity and histology of animals were compared following a 12-week swimming training. Animals were divided into sedentary male (MS), trained male (MTr), sedentary female (FS), and trained female (FTr) groups. Isolated femoral artery rings were examined by wire myography. Contraction induced by phenylephrine (Phe) did not differ between the four groups. The contractile ability in the presence of indomethacin (INDO) was decreased in both sedentary groups. However, we found a specific cyclooxygenase-2 (COX-2) role only in FS rats. After exercise training, we observed increased vasoconstriction in both sexes, when nitro-L-arginine methyl ester (L-NAME) was present. The COX-dependent vasoconstriction effect disappeared in MTr animals, and the COX-2-dependent vasoconstriction effect disappeared in FTr ones. Relaxation was reduced significantly, when L-NAME was present in MTr animals compared to in FTr rats. The training was associated with greater endothelial nitric oxide synthase (eNOS) protein expression in males, but not in females. The present study proves that there are gender differences regarding adaptation mechanisms of musculocutaneous arteries to sports training. In males, relaxation reserve capacity was markedly elevated compared to in females.

Hydatidiform mole is an extremely rare gestational trophoblastic disease. The pathogenesis is unique in that the maternal tumor arises from pregnancy tissue. In terms of occurrence, it mainly affects women of reproductive age. In our case report, a 53-year-old female patient was diagnosed with molar pregnancy as the background of her perimenopausal bleeding disorder. Mola is a high-risk disease because the symptoms can be deceiving and may be very similar to those of an incomplete miscarriage, ectopic pregnancy or perimenopausal bleeding. Appropriate diagnosis is key to terminating the pregnancy as soon as possible. The purpose of our case report is to draw attention to the atypical appearance of molar pregnancy; in relation to our perimenopausal female patient, we review the basic principles of treatment of hydatidiform mole and present the diagnostic and therapeutic management of a successfully completed case.

Background: Reactive Oxygen Species (ROS) are required for intact spermatogenesis and sperm function, but excessive levels will cause oxidative stress, impairing sperms and sperm function due to membrane damage and DNA fragmentation., Objective: Theoretically, antioxidant supplementation may act as a protection system against free radicals. Since infertile males have higher levels of ROS, nutritional supplements are widely used for protecting sperms. In the recent review, the authors summarize the most recent data regarding the effect of antioxidant treatment and draw the attention of the limitations of antioxidant use in male infertility., Methods: The recent review gives an update of antioxidant treatment in male infertility., Results: Improvement of sperm parameters was reported in the majority of studies. Comparing different antioxidants versus placebo showed low certainty of evidence with a serious risk of bias, and there is a lack regarding certain doses, pregnancy rate, and live birth rate outcomes. Various clinical studies and randomized control trials reported negative outcomes. Conflicting findings lead the attention to the study of biochemical features of the oxidant vs. antioxidant equilibrium. Higher exposure to antioxidants will result in "reductive stress", which has harmful effects on sperm function, moreover can negatively influence embryo development. Reductive stress is as dangerous as oxidative stress and may act as a cause of different human pathologies., Conclusion: An intact balance of oxidant and antioxidant systems is required for normal sperm function. No guideline exists for the antioxidant dose regimen and treatment duration. Overdosing can result in reductive stress, which is also harmful to fertility and can cause several diseases. Assessment of the pre-treatment redox status can be recommended before the administration of exogenous antioxidants., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: Little is known about the potential role of central obesity among men. Our first aim was to confirm what is already known from prior research, namely that both BMI and WHR are inversely associated with selected semen parameters. Our second aim was to examine the potential role of central obesity by assessing if there was a difference between BMI and WHR regarding their relationships to these selected semen parameters., Methods: In this cross-sectional study between January 2011 to January 2018, we analyzed semen samples from 1169 patients who visited an andrology clinic in Budapest for infertility reasons. Variables assessed were: body measurements (height, weight, waist circumference, and hip circumference), and the results of semen analysis (sperm concentration, total sperm count, progressive sperm motility, and normal sperm morphology)., Results: The mean height and weight were 180.6 cm and 87.3 kg, respectively - the mean BMI was 26.8. The mean waist and hip circumferences were 100.9 cm and 94.8 cm, respectively - the mean waist to hip ratio was 0.94. The mean sperm concentration, total sperm count, and percents of progressive motility and normal morphology were 48.7 M/ml, 165 million, 21.2, and 4.8%, respectively. Both BMI and WHR were significant correlates in all semen parameter regression models. When comparing the parameter estimates for BMI with those for WHR for each semen parameter, the parameter estimate for WHR was significantly lower (indicating a stronger negative association) than that for BMI for progressive motility and total sperm count, but not for normal morphology or concentration., Conclusions: Our study is the first to examine, using a large patient sample, the potential role of central obesity by comparing the difference between BMI and WHR as they relate to selected semen parameters. Our findings indicate a potential role of central obesity for progressive motility and total sperm count, but not for normal morphology and concentration. Despite the limitations and the exploratory nature of this study, we can conclude that our results point to a potential role of central obesity in male infertility, but this finding should be confirmed and further explored in future research., Trial Registration: The trial was retrospectively authorized after the data collection on September 24, 2018. Registration number: SE RKEB: 169/2018.

Recent advances in sequencing technologies have made it significantly easier to find the genetic roots of rare hereditary pediatric diseases. These novel methods are not panaceas, however, and they often give ambiguous results, highlighting multiple possible causative mutations in affected patients. Furthermore, even when the mapping results are unambiguous, the affected gene might be of unknown function. In these cases, understanding how a particular genotype can result in a phenotype also needs carefully designed experimental work. Model organism genetics can offer a straightforward experimental setup for hypothesis testing. Containing orthologs for over 80% of the genes involved in human diseases, zebrafish ( Danio rerio ) has emerged as one of the top disease models over the past decade. A plethora of genetic tools makes it easy to create mutations in almost any gene of the zebrafish genome and these mutant strains can be used in high-throughput preclinical screens for active molecules. As this small vertebrate species offers several other advantages as well, its popularity in biomedical research is bound to increase, with "aquarium to bedside" drug development pipelines taking a more prevalent role in the near future.

Recombinant human erythropoietins (rHuEPOs) are used to treat cancer-related anemia. Recent preclinical studies and clinical trials, however, have raised concerns about the potential tumor-promoting effects of these drugs. Because the clinical significance of erythropoietin receptor (EPOR) signaling in human non-small cell lung cancer (NSCLC) also remains controversial, our aim was to study whether EPO treatment modifies tumor growth and if EPOR expression has an impact on the clinical behavior of this malignancy. A total of 43 patients with stage III-IV adenocarcinoma (ADC) and complete clinicopathological data were included. EPOR expression in human ADC samples and cell lines was measured by quantitative real-time polymerase chain reaction. Effects of exogenous rHuEPOα were studied on human lung ADC cell lines in vitro. In vivo growth of human ADC xenografts treated with rHuEPOα with or without chemotherapy was also assessed. In vivo tumor and endothelial cell (EC) proliferation was determined by 5-bromo-2'-deoxy-uridine (BrdU) incorporation and immunofluorescent labeling. Although EPOR mRNA was expressed in all of the three investigated ADC cell lines, rHuEPOα treatment (either alone or in combination with gemcitabine) did not alter ADC cell proliferation in vitro. However, rHuEPOα significantly decreased tumor cell proliferation and growth of human H1975 lung ADC xenografts. At the same time, rHuEPOα treatment of H1975 tumors resulted in accelerated tumor endothelial cell proliferation. Moreover, in patients with advanced stage lung ADC, high intratumoral EPOR mRNA levels were associated with significantly increased overall survival. This study reveals high EPOR level as a potential novel positive prognostic marker in human lung ADC.

The hepatocyte growth factor/scatter factor (HGF/SF) tyrosine kinase (TK) receptor c-Met plays a crucial role in the development of the invasive phenotype of tumors and thus represents an attractive candidate for targeted therapies in a variety of malignancies, including human malignant melanoma (MM). In contrast to what has been shown previously, we were not able to detect any genetic alterations, either in the juxtamembrane- or in the TK-domain of c-Met, in the studied MM cell lines. Nevertheless, c-Met was constitutively active in these cell lines without exogenous HGF/SF stimulation. The active receptor was localized to the adhesion sites of the cells. Addition of the c-Met TK inhibitor SU11274 specifically decreased the phosphotyrosine signal at the focal adhesions sites, which was accompanied by a decrease in cell proliferation as well as an increase in apoptotic cells. In addition, non-apoptotic concentrations of SU11274 significantly reduced the in vitro migratory capacity of MM cells in the modified Boyden-chamber assay. Administration of SU11274 significantly decreased primary tumor growth as well as the capacity for liver colony formation of MM cells in SCID mice. Our study provides the first evidence for an in vivo antitumor activity of SU11274 in a human melanoma xenograft model, and suggests c-Met as a valid target for the therapy of MM. Consequently, SU11274 treatment might represent a useful strategy for controlling melanoma progression and metastasis in patients with MM.
