Association between human papillomavirus and preterm delivery: A systematic review and meta-analysis.

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.

Platelet-rich plasma (PRP) treatment of the ovaries significantly improves fertility parameters and reproductive outcomes in diminished ovarian reserve patients: a systematic review and meta-analysis.

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.

Sociodemographic and Medical Characteristics of Women Applied for Emergency Contraception-A Retrospective Observational Study.

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.

Motivators for emergency contraception: Previous pregnancy and condom rupture.

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.

Comparison of Combined Parenteral and Oral Hormonal Contraceptives: A Systematic Review and Meta-Analysis of Randomized Trials.

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; I2 = 0%). We found significant subgroup differences between parenteral methods in terms of compliance (χ2 = 4.32, p =0.038, I2 = 80%) and certain adverse events: breast discomfort (χ2 = 19.04, p =0.001, I2 = 80%), nausea (χ2 = 8.04, p =0.005, I2 = 75%), and vomiting (χ2 = 9.30, p =0.002; I2 = 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.

[Emergency contraception.] / Esemény utáni fogamzásgátlás.

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.

[Herniated amniotic sac through uterine dehiscence at the 30th gestational week after prior laparoscopic salpingectomy]. / Elozetes laparoszkópos salpingectomiát követo hegszétválás és buroksérv a várandósság 30. hetében.

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.

Impact of Sex and Exercise on Femoral Artery Function: More Favorable Adaptation in Male Rats.

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.

[Molar pregnancy in postmenopause]. / Molaterhesség postmenopausában.

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.

Administration of Antioxidants in the Infertile Male: When it may have a Beneficial Effect?

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.

The potential role of central obesity in male infertility: body mass index versus waist to hip ratio as they relate to selected semen parameters.

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.
