Twenty-five patients were included, and follicular fluid and serum samples were analysed for various mycotoxins. Principal observations:1.

Strong Early Impact of Letrozole on Ovulation Induction Outperforms Clomiphene Citrate in Polycystic Ovary Syndrome.

Polycystic ovary syndrome is a common endocrine disorder, characterized by hyperandrogenism and/or chronic oligo/anovulation, which leads to infertility. The aim of this systematic review and meta-analysis was to explore the efficacy of letrozole compared with clomiphene citrate for ovulation induction in women with polycystic ovarian syndrome. The study protocol has been registered with PROSPERO (registration number CRD42022376611).

Comprehensive Assessment of Labiaplasty Techniques and Tools, Satisfaction Rates, and Risk Factors: A Systematic Review and Meta-analysis.

Background: Various surgical techniques have been devised for the surgical cosmetic enhancement of female outer genitalia. The selection of an optimal method should be based on satisfaction rates and safety; however, comprehensive, contemporary systematic assessment of these factors has been limited in the literature.

Objectives: Our aim was to conduct a comprehensive systematic review and meta-analysis to evaluate the overall satisfaction rates and risk factors associated with various labiaplasty techniques and tools.

The Possible Role of Mycotoxins in the Pathogenesis of Endometrial Cancer.

Endometrial cancer is one of the most common cancer types among women. Many factors can contribute to the development of this disease, including environmental factors and, thus, eating habits. Our study aims to determine the levels of various mycotoxins and their metabolites in the blood serum and endometrial tissue samples of participants with previously proven endometrial cancer and to find possible contributions to cancer development.

Robot-assisted laparoscopy does not have demonstrable advantages over conventional laparoscopy in endometriosis surgery: a systematic review and meta-analysis.

Background: Endometriosis is a chronic condition affecting 6-10% of women of reproductive age, with endometriosis-related pain and infertility being the leading symptoms. Currently, the gold standard treatment approach to surgery is conventional laparoscopy (CL); however, the increasing availability of robot-assisted surgery is projected as a competitor of CL. This study aimed to compare the perioperative outcomes of robot-assisted laparoscopy (RAL) and CL in endometriosis surgery.

[Possible applications of poultry immunoglobulins focusing on mycotoxin environmental loads and human influence].

In addition to their role, immunoglobulins can be used in animal and human diagnostic (immunoassay-based) measurements, prophylaxis and (immuno)therapy. For these purposes, today's "alternative" that is advantageous from an animal ethical point of view is the bird immunoglobulin Y isolated from egg yolk. Its development and production are cost-effective, the complexity is low, and due to its advantageous properties, it can be used in assays or even more so in medical therapies (primarily passive immunization).

[Successful pregnancy of a patient with primary sclerosing cholangitis awaiting liver transplantation].

In women, primary sclerotising cholangitis (PSC) associated with ulcerative colitis and intrahepatic cholestasis is a rare disease. To date, there are no data from Hungary on the fertility and pregnancy outcome of women with this chronic liver disease. Our aim is to present the favorable pregnancy outcome of a woman with PSC associated with ulcerative colitis, intrahepatic cholestasis and postpartum colectomy, and review of the literature.

Additive damage in the thromboxane related vasoconstriction and bradykinin relaxation of intramural coronary resistance arterioles in a rodent model of andropausal hypertension.

Hypertension and andropause both accelerate age-related vascular deterioration. We aimed to evaluate the effects of angiotensin-II induced hypertension and deficiency of testosterone combined regarding the resistance coronaries found intramurally. Four male groups were formed from the animals: control group (Co, n = 10); the group that underwenr orchidectomy (ORC, n = 13), those that received an infusion of angiotensin-II (AII, n = 10) and a grous that received AII infusion and were also surgically orchidectomized (AII + ORC, n = 8).

Depressed calcium cycling contributes to lower ischemia tolerance in hearts of estrogen-deficient rats.

Objective: Estrogens enhance ischemia tolerance (IT) in the myocardium, the mechanism of which remains unclear. We investigated the effects of long-term estrogen deprivation on the intracellular calcium (Ca(2+)(i)) transient of the heart and its possible influence on IT.

Methods: Hearts of ovariectomized (OVX) and sham-operated (control) adult female rats (some receiving estrogen therapy) were studied 10 weeks after surgical operation: control (n = 8), OVX (n = 10), sham-operated estrogen-substituted (n = 7), and ovariectomized estrogen-substituted (n = 9).

Antioxidant effect of the active metabolites of tibolone.

Certain steroidal compounds have an antioxidant effect in humans. Our aim was to test whether the synthetic steroid tibolone and its metabolites are also able to display such a property. For this, granulocytes from healthy men and women were incubated for two hours with different concentrations (10(-7), 10(-8), 10(-9 )M) of either estradiol, tibolone, 3α-hydroxytibolone, 3β-hydroxytibolone, Δ(4)-tibolone, 3α-sulfated-tibolone, 3α-17β-disulfated-tibolone, 3β-sulfated-tibolone or 3β-17β-disulfated-tibolone.

Lower-limb veins are thicker and vascular reactivity is decreased in a rat PCOS model: concomitant vitamin D3 treatment partially prevents these changes.

Polycystic ovary syndrome (PCOS) causes vascular damage to arteries; however, there are no data for its effect on veins. Our aim was to clarify the effects of dihydrotestosterone (DHT)-induced PCOS both on venous biomechanics and on pharmacological reactivity in a rat model and to test the possible modulatory role of vitamin D3 (vitD). PCOS was induced in female Wistar rats by DHT treatment (83 μg/day, subcutaneous pellet).

Effects of vitamin D3 derivative--calcitriol on pharmacological reactivity of aortic rings in a rodent PCOS model.

Background: The aim of this study was to examine the effects of the hyperandrogenic state in dihydrotestosterone (DHT)-induced polycystic ovary syndrome (PCOS), the vascular responses to different vasoactive agents, and the modulatory role of vitamin D3.

Methods: APCOS model was induced by DHT application in 20 female Wistar rats. Ten of the DHT treated rats simultaneously received calcitriol treatment.

Altered insulin-induced relaxation of aortic rings in a dihydrotestosterone-induced rodent model of polycystic ovary syndrome.

Objective: To clarify the effects of dihydrotestosterone (DHT)-induced polycystic ovary syndrome (PCOS) on the insulin-dependent vasodilatation of the thoracic aorta and the role of vitamin D in a rat model.

Design: Controlled experimental animal study.

Setting: Laboratory.

Pharmacological reactivity of resistance vessels in a rat PCOS model - vascular effects of parallel vitamin D₃ treatment.

The aim of this study was to clarify the effects of dihydrotestosterone (DHT)-induced polycystic ovary syndrome (PCOS) on pharmacological reactivity of a resistance vessel in a rat model and the possible modulatory role of 1,25-(OH)₂-cholecalciferol (vitamin D₃). The PCOS model was induced in adolescent female Wistar rats by a 10-week DHT treatment. Norepinephrine induced contractility and acetylcholine relaxation were tested in arterioles by pressure arteriography in control as well as DHT- and DHT plus vitamin D₃-treated (DHT+D3) animals.

[Ultrasonography in the diagnosis of ovarian and endometrial carcinoma].

Transvaginal sonography has become a crucial part of the routine gynecologic examination. It offers now a great help in the diagnosis of almost all gynecological diseases. Transvaginal ultrasound means the first step in the diagnosis of the first two most common gynecological malignancies, and in many cases we are able to set up a diagnosis of its own.

[Spontaneous aortic rupture during pregnancy].

Aortic dissection is a rare entity. Half of the aortic dissection cases occur during pregnancy in women under the age of 40. The authors report a case of a multiparous woman at the third trimester of her sixth pregnancy, who died from a sudden and intractable cardiovascular shock.

Successful management of pregnancy with nephrotic syndrome due to preexisting membranous glomerulonephritis: a case report.

The influence of membranous glomerulonephritis (MGN) on maternal and fetal outcome is controversial, as is the effect of pregnancy on the course of preexisting nephrotic syndrome. We report a case of successful management of a pregnancy with preexisting severe nephrotic syndrome due to biopsy-proven primary MGN. Our patient became pregnant in a non-compliance period, discontinued the nephrological follow-up program and her kidney disease decompensated.
