Very young and advanced maternal age strongly elevates the occurrence of nonchromosomal congenital anomalies: a systematic review and meta-analysis of population-based studies.

BACKGROUND: Nonchromosomal congenital anomalies (NCAs) are the most common cause of infant mortality and morbidity. The role of maternal age is well known, although the specifics are not thoroughly elucidated in the literature. OBJECTIVE: To evaluate the role of maternal age in the incidence of NCAs and to pinpoint age groups at higher risk to refine screening protocols. STUDY DESIGN: A systematic review and meta-analysis were conducted following the PRISMA 2020 guidelines and Cochrane Handbook. Searches were performed on October 19, 2021, across MEDLINE (via PubMed), Cochrane Library (CENTRAL), and Embase. Population-based studies assessing the impact of maternal age on the incidence of NCAs in pregnant women were included, without restrictions on age range, country, or comorbidities. A random-effects model was used for pooling effect sizes, considering the heterogeneity across studies. RESULTS: From 15,547 studies, 72 were synthesized. Maternal age >35 showed an increased NCA risk (risk ratio [RR]: 1.31, confidence interval [CI]: 1.07 -1.61), rising notably after>40 (RR: 1.44, CI: 1.25 -1.66). The latter changes to 1.25 (CI: 1.08 -1.46) if the co-occurrence of chromosomal aberrations is excluded. Specific anomalies like cleft lip/palate (>40, RR: 1.57, CI: 1.11 -2.20) and circulatory system defects (>40, RR: 1.94, CI: 1.28 -2.93) were significantly associated with advanced maternal age. Conversely, gastroschisis was linked to mothers <20 (RR: 3.08, CI: 2.74 -3.47). CONCLUSION: The study confirms that both very young and advanced maternal ages significantly increase the risk of NCAs. There is a pressing need for age-specific prenatal screening protocols to better detect these anomalies, especially considering the current trend of delayed childbearing. Further research is required to fully understand the impact of maternal age on the prevalence of rarer NCAs.

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. OBJECTIVES: We aimed to compare the effectiveness and safety of these two procedures. METHODS: A systematic search was conducted in three medical databases. Studies investigating different perioperative outcomes of endometriosis-related surgeries were included. Results are presented as odds ratios (OR) or mean differences (MD) with 95% confidence intervals (CI). RESULTS: Our search yielded 2,014 records, of which 13 were eligible for data extraction. No significant differences were detected between the CL and RAL groups in terms of intraoperative complications (OR = 1.07, CI 0.43-2.63), postoperative complications (OR = 1.3, CI 0.73-2.32), number of conversions to open surgery (OR = 1.34, CI 0.76-2.37), length of hospital stays (MD = 0.12, CI 0.33-0.57), blood loss (MD = 16.73, CI 4.18-37.63) or number of rehospitalizations (OR = 0.95, CI 0.13-6.75). In terms of operative times (MD = 28.09 min, CI 11.59-44.59) and operating room times (MD = 51.39 min, CI 15.07-87.72;), the RAL technique remained inferior. CONCLUSION: RAL does not have statistically demonstrable advantages over CL in terms of perioperative outcomes for endometriosis-related surgery.

Ranking the dietary interventions by their effectiveness in the management of polycystic ovary syndrome: a systematic review and network meta-analysis.

INTRODUCTION: Polycystic ovary syndrome (PCOS) is a common condition in women, characterised by reproductive and metabolic dysfunction. While dietary approaches have been evaluated as a first-line treatment for patients with PCOS, there is limited evidence to support preference for a specific dietary composition. This systematic review and network meta-analysis was performed with the objective of comparing different dietary interventions in terms of positive impact. Metformin, the currently preferred treatment, was also compared. METHODS: The latest systematic search was performed on the 20th of March, 2023. Eligible randomised controlled trials (RCTs) included patients with PCOS and compared the dietary approach with another intervention or a standard diet. Outcomes were expressed via anthropometric measurements and hormonal, glycemic, and lipid levels. The Bayesian method was used to perform a network meta-analysis and to calculate the surface under the cumulative ranking curve (SUCRA) values in order to rank the dietary interventions. The overall quality of the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation system. RESULTS: 19 RCTs were identified, comprising data from 727 patients who were variously treated with 10 types of dietary interventions and metformin. The Dietary Approaches to Stop Hypertension (DASH) diet was the most effective in reducing Homeostatic Model Assessment of Insulin Resistance (SUCRA 92.33%), fasting blood glucose (SUCRA 85.92%), fasting insulin level (SUCRA 79.73%) and triglyceride level (SUCRA 82.07%). For body mass index (BMI), the most effective intervention was the low-calorie diet (SUCRA 84.59%). For weight loss, the low-calorie diet with metformin (SUCRA 74.38%) was the most effective intervention. Metformin produced the greatest reductions in low-density lipoprotein cholesterol (SUCRA 78.08%) and total testosterone levels (SUCRA 71.28%). The low-carb diet was the most effective intervention for reducing cholesterol levels (SUCRA 69.68%), while the normal diet (SUCRA 65.69%) ranked first for increasing high-density lipoprotein cholesterol levels. CONCLUSION: Dietary interventions vary in their effects on metabolic parameters in women with PCOS. Based on our results, the DASH diet is the most effective dietary intervention for treating PCOS.

Inositol-Exchange Activity in Human Primordial Placenta.

Human placenta is an intensively growing tissue. Phosphatidylinositol (PI) and its derivatives are part of the signaling pathway in the regulation of trophoblast cell differentiation. There are two different enzymes that take part in the direct PI synthesis: phosphatidylinositol synthase (PIS) and inositol exchange enzyme (IE). The presence of PIS is known in the human placenta, but IE activity has not been documented before. In our study, we describe the physiological properties of the two enzymes in vitro. PIS and IE were studied in different Mn2+ and Mg2+ concentrations that enabled us to separate the individual enzyme activities. Enzyme activity was measured by incorporation of 3[H]inositol in human primordial placenta tissue or microsomes. Optimal PIS activity was achieved between 0.5 and 2.0 mM Mn2+ concentration, but higher concentrations inhibit enzyme activity. In the presence of Mg2+, the enzyme activity increases continuously up to a concentration of 100 mM. PIS was inhibited by nucleoside di- and tri-phosphates. PI production increases between 0.1 and 10 mM Mn2+ concentration. The incorporation of [3H]inositol into PI increased by 57% when adding stabile GTP analog. The described novel pathway of inositol synthesis may provide an additional therapeutic approach of inositol supplementation before and during pregnancy.

Decreased Expression of Placental Proteins in Recurrent Pregnancy Loss: Functional Relevance and Diagnostic Value.

Miscarriages affect 50-70% of all conceptions and 15-20% of clinically recognized pregnancies. Recurrent pregnancy loss (RPL, ≥2 miscarriages) affects 1-5% of recognized pregnancies. Nevertheless, our knowledge about the etiologies and pathophysiology of RPL is incomplete, and thus, reliable diagnostic/preventive tools are not yet available. Here, we aimed to define the diagnostic value of three placental proteins for RPL: human chorionic gonadotropin free beta-subunit (free-ß-hCG), pregnancy-associated plasma protein-A (PAPP-A), and placental growth factor (PlGF). Blood samples were collected from women with RPL (n = 14) and controls undergoing elective termination of pregnancy (n = 30) at the time of surgery. Maternal serum protein concentrations were measured by BRAHMS KRYPTOR Analyzer. Daily multiple of median (dMoM) values were calculated for gestational age-specific normalization. To obtain classifiers, logistic regression analysis was performed, and ROC curves were calculated. There were differences in changes of maternal serum protein concentrations with advancing healthy gestation. Between 6 and 13 weeks, women with RPL had lower concentrations and dMoMs of free ß-hCG, PAPP-A, and PlGF than controls. PAPP-A dMoM had the best discriminative properties (AUC = 0.880). Between 9 and 13 weeks, discriminative properties of all protein dMoMs were excellent (free ß-hCG: AUC = 0.975; PAPP-A: AUC = 0.998; PlGF: AUC = 0.924). In conclusion, free-ß-hCG and PAPP-A are valuable biomarkers for RPL, especially between 9 and 13 weeks. Their decreased concentrations indicate the deterioration of placental functions, while lower PlGF levels indicate problems with placental angiogenesis after 9 weeks.

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, a comprehensive, contemporary systematic assessment of these factors in 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. METHODS: The authors performed a systematic literature search in three medical databases: PubMed, Elsevier and Cochrane Library (CENTRAL) with the closing date of October 2023. Original articles with quantitative satisfaction rates and frequencies of most common complications (hematoma, dehiscence, swelling, bleeding and infection) were included. RESULTS: Systematic search provided a total of 3954 records. After selection and review of the articles, 86 eligible, peer-reviewed studies were identified, of which 53 provided quantitative data. High overall satisfaction rate was found for all methods (Prop: 94%; CI: 93-95%), with highest satisfaction for deepithelization (Prop: 97%; CI: 85%-99%). Complications were generally rare, with elevated incidences for some techniques (wedge resection - dehiscence: Prop: 8%; CI: 5%-13% and composite reduction - swelling: Prop: 13%; CI: 2%-54%). Scalpel has significantly higher incidence of complications than laser, namely for bleeding, swelling and hematoma. CONCLUSIONS: Labiaplasty can be considered a generally effective approach to outer female genitalia beautification, with low associated risks. Surgeons must tailor their approach to the patients' needs and anatomy to achieve maximal satisfaction, given the differences in the frequency of complications for each method.

Lifestyle-, environmental-, and additional health factors associated with an increased sperm DNA fragmentation: a systematic review and meta-analysis.

INTRODUCTION: Infertility affects one in every six couples in developed countries, and approximately 50% is of male origin. In 2021, sperm DNA fragmentation (SDF) testing became an evidence-based test for fertility evaluations depicting fertility more clearly than standard semen parameters. Therefore, we aimed to summarize the potential prognostic factors of a higher SDF. METHODS: We conducted a systematic search in three medical databases and included studies investigating any risk factors for SDF values. We calculated mean differences (MD) in SDF with 95% confidence interval (CI) for exposed and non-exposed individuals. RESULTS: We included 190 studies in our analysis. In the group of associated health conditions, varicocele (MD = 13.62%, CI: 9.39-17.84) and impaired glucose tolerance (MD = 13.75%, CI: 6.99-20.51) had the most significant increase in SDF. Among malignancies, testicular tumors had the highest impact, with a maximum of MD = 11.3% (CI: 7.84-14.76). Among infections, the overall effects of both Chlamydia and HPV were negligible. Of lifestyle factors, smoking had the most disruptive effect on SDF - an increase of 9.19% (CI: 4.33-14.06). Different periods of sexual abstinence did not show significant variations in SDF values. Age seemed to have a more drastic effect on SDF from age 50 onwards, with a mean difference of 12.58% (CI: 7.31-17.86). Pollution also had a detrimental effect - 9.68% (CI: 6.85-12.52). CONCLUSION: Of the above risk factors, varicocele, impaired glucose tolerance, testicular tumors, smoking, pollution, and paternal age of over 50 were associated with the highest SDF.

Inositol is an effective and safe treatment in polycystic ovary syndrome: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Metformin is the gold standard insulin sensitizer, which is widely used to treat insulin resistance in polycystic ovary syndrome (PCOS). However, metformin may induce gastrointestinal side effects. OBJECTIVE: Inositols have long been debated as a potential alternative for metformin in treating PCOS. Therefore, the present systematic review aimed to evaluate the efficacy and safety of inositols in treating PCOS. METHODS: The present systematic search was performed in CENTRAL, MEDLINE, and Embase from the inception until October 20th, 2021. Eligible randomized controlled trials (RCTs) included women diagnosed with PCOS and compared any inositols with metformin or placebo. Our primary outcome was cycle normalization, whereas secondary outcomes were body mass index (BMI), parameters of carbohydrate metabolism and clinical and laboratory hyperandrogenism. Results are reported as risk ratios or mean differences (MDs) with 95% confidence intervals (CIs). RESULTS: Twenty-six RCTs were identified, including data of 1691 patients (806 inositol, 311 with placebo, and 509 metformin groups). In patients treated with inositols, the risk (CI: 1.13; 2.85) of having a regular menstrual cycle was found by 1.79 higher than in the case of placebo. Moreover, the inositols showed non-inferiority compared to metformin in this outcome. In the case of BMI (MD = -0.45; CI: -0.89; -0.02), free testosterone (MD = -0,41, CI: -0.69; -0.13), total testosterone (MD = -20.39, CI: -40.12; -0.66), androstenedione (MD = -0.69, CI: -1,16; -0.22), glucose (MD = -3.14; CI: -5.75; -0.54) levels and AUC insulin (MD = -2081.05, CI: -2745.32; -1416.78) inositol treatment induced greater decrease compared to placebo. Inositol increased sex-hormone-binding globulin significantly compared to placebo (MD = 32.06, CI:1.27; 62.85). CONCLUSION: Inositol is an effective and safe treatment in PCOS. Moreover, inositols showed non-inferiority in most outcomes compared to the gold standard treatment; metformin. TRIAL REGISTRATION: PROSPERO registration number: CRD42021283275.

Variable fragment length allele-specific polymerase chain reaction (VFLASP), a method for simple and reliable genotyping.

Single-nucleotide polymorphism (SNP) is a substitution of a single nucleotide at a specific position in the genome. Until now, 585 million SNPs have been identified in the human genome, and therefore, a widely applicable method is desirable to detect a specific SNP. Herein we report a simple and reliable genotyping assay, which seems to be suitable for medium and small size laboratories, as well, to easily genotype most of the SNPs. In our study, all of the possible base variations (A-T, A-G, A-C, T-G, T-C, G-C) were tested to prove the general feasibility of our technique. The basis of the assay is a fluorescent PCR, in which both allele-specific primers, differing only at the 3' end according to the sequence of the SNP, were present, and the length of one of them was modified with 3 bp by adding an adapter sequence to the 5' end of that primer. The competitive presence of both allele-specific primers excludes the false amplification of the absent allele (which can happen in simple allele-specific PCR (AS-PCR)) and ensures the amplification of the proper allele(s). Unlike other complicated genotyping methods that use of manipulation of fluorescent dyes for genotyping, we apply an approach based on the length of amplicons from different alleles to differentiate between them. In our experiment (named variable fragment length allele-specific polymerase chain reaction (VFLASP)), the investigated six SNPs, containing the six available base variations, gave clear and reliable results after detecting the amplicons by capillary electrophoresis.

Maternal age is highly associated with non-chromosomal congenital anomalies: Analysis of a population-based case-control database.

OBJECTIVE: The role of maternal age in the development of non-chromosomal congenital anomalies (NCAs) is under debate. Therefore, the primary aim of this study was to identify the age groups at risk for NCAs. The secondary aim was to perform a detailed analysis of the relative frequency of various anomalies. DESIGN: National population-based study. SETTING: The Hungarian Case-Control Surveillance of Congenital Anomalies (CAs) between 1980 and 2009. POPULATION OR SAMPLE: A cohort of 31 128 cases with confirmed NCAs was compared with Hungary's total of 2 808 345 live births. METHODS: Clinicians prospectively reported cases after delivery. Data were analysed by non-linear logistic regression. Risk-increasing effect of young and advanced maternal age was determined by each NCA group. MAIN OUTCOME MEASURES: These were the total number of NCAs: cleft lip and palate, circulatory, genital, musculoskeletal, digestive, urinary, eye, ear, face, and neck, nervous system, and respiratory system anomalies. RESULTS: The occurrence of NCAs in our database was lowest between 23 and 32 years of maternal age at childbirth. The relative risk (RR) of any NCA was 1.2 (95% CI 1.17-1.23) and 1.15 (95% CI 1.11-1.19) in the very young and advanced age groups, respectively. The respective results for the circulatory system were RR = 1.07 (95% CI 1.01-1.13) and RR = 1.33 (95% CI 1.24-1.42); for cleft lip and palate RR = 1.09 (95% CI 1.01-1.19) and RR = 1.45 (95% CI 1.26-1.67); for genital organs RR = 1.15 (95% CI 1.08-1.22) and RR = 1.16 (95% CI 1.04-1.29); for the musculoskeletal system RR = 1.17 (95% CI 1.12-1.23) and RR = 1.29 (95% CI 1.14-1.44); and for the digestive system RR = 1.23 (95% CI 1.14-1.31) and RR = 1.16 (95% CI 1.04-1.29). CONCLUSION: Very young and advanced maternal ages are associated with different types of NCAs. Therefore, screening protocols should be adjusted for these risk groups.

Comprehensive Analysis of the Prognostic Value of Circulating MMP-7 Levels in Urothelial Carcinoma: A Combined Cohort Analysis, Systematic Review, and Meta-Analysis.

Lymph node (LN) status is the most significant prognostic factor for invasive urothelial bladder cancer (UBC); however, the optimal extent of LN dissection (LND) is debated. We assessed circulating matrix metalloproteinase-7 (MMP-7) as a prognostic factor and decision-making marker for the extent of LND. Preoperative serum MMP-7 levels were determined in two independent UBC cohorts (n = 188; n = 68) and in one control cohort (n = 97) by using the ELISA method. A systematic review and meta-analysis on the prognostic role of circulating pretreatment MMP-7 levels were performed. Serum MMP-7 levels were higher in patients compared to controls (p < 0.001) with the highest levels in LN-positive cases. Half of LN-positive UBC patients had low MMP-7 levels, whereas the survival of LN-negative patients with high serum MMP-7 findings was poor. MMP-7 levels were independently associated with poor survival in both cohorts (p = 0.006, p < 0.001). Accordingly, our systematic review of six eligible publications revealed a 2.5-fold higher mortality risk in patients with high MMP-7 levels. In conclusion, preoperative MMP-7 level is a validated and independent prognostic factor in urothelial cancer. It cannot be used to decide between regional or extended LND but may be useful in identifying LN-negative high-risk patients with potentially undetected metastases.

Effects of Gender and Vitamin D on Vascular Reactivity of the Carotid Artery on a Testosterone-Induced PCOS Model.

The negative cardiovascular effects of polycystic ovary syndrome (PCOS) and vitamin D deficiency (VDD) have been discussed previously; however, the sex differences between PCOS females and males are not yet known. Our aim was to investigate the effect of PCOS and VDD in the carotid artery of male and female Wistar rats. Females were treated with transdermal testosterone (Androgel) for 8 weeks, which caused PCOS. VDD and vitamin D supplementation were accomplished via diet. The carotid arteries' contraction and relaxation were examined using myography. Receptor density was investigated using immunohistochemistry. In PCOS females, angiotensin receptor density, angiotensin II-induced contraction, androgen receptor optical density, and testosterone-induced relaxation increased. The increased contractile response may increase cardiovascular vulnerability in women with PCOS. As an effect of VDD, estrogen receptor density increased in all our groups, which probably compensated for the reduced relaxation caused by VDD. Testosterone-induced relaxation was decreased as a result of VDD in males and non-PCOS females, whereas this reduction was absent in PCOS females. Male sex is associated with increased contraction ability compared with non-PCOS and PCOS females. VDD and Androgel treatment show significant gender differences in their effects on carotid artery reactivity. Both VDD and PCOS result in a dysfunctional vascular response, which can contribute to cardiovascular diseases.

Sex differences in rat renal arterial responses following exercise training.

During aerobic exercise, hemodynamic alterations occur. Although blood flow in skeletal muscle arteries increases, it decreases in visceral vessels because of mesenterial vasoconstriction. However, maintaining renal blood flow during intensive sport is also a priority. Our aim was to investigate the changes of vascular reactivity and histology of isolated renal artery of male and female rats in response to swim training. Wistar rats were distributed into four groups: male sedentary (MSed), male trained (MTr), female sedentary (FSed), and female trained (FTr). Trained animals underwent a 12-wk-long intensive swimming program. Vascular function of isolated renal artery segments was examined by wire myography. Phenylephrine-induced contraction was lower in FSed than in MSed animals, and it was decreased by training in male but not in female animals. Inhibition of cyclooxygenases by indomethacin reduced contraction in both sedentary groups, and in MTr but not in FTr animals. Inhibition of nitric oxide production increased contraction in both trained groups. Acetylcholine induced relaxation was similar in all experimental groups showing predominant NO-dependency. Elastin and smooth muscle cell actin density was reduced in female rats after aerobic training. This study shows that, as a result of a 12-wk-long training, there are sex differences in renal arterial responses following exercise training. Swimming moderates renal artery vasoconstriction in male animals, whereas it depresses elastic fiber and smooth muscle actin density in females.NEW & NOTEWORTHY We provided the first detailed analysis of the adaptation of the renal artery after aerobic training in male and female rats. As a result of a 12-wk-long training program, the pharmacological responses of renal arteries changed only in male animals. In phenylephrine-induced contraction, cyclooxygenase-mediated vasoconstriction mechanisms lost their significance in female rats, whereas NO-dependent relaxation became a significant contraction reducing factor in both sexes. Early structural changes, such as reduced elastin and smooth muscle cell actin evolves in females.

Challenges of and possible solutions for living with endometriosis: a qualitative study.

BACKGROUND: Endometriosis as a chronic gynecological disease has several negative effects on women's life, thereby placing a huge burden on the patients and the health system. The negative impact of living with endometriosis (impaired quality of life, diverse medical experiences) is detailed in the literature, however, we know less about patients' self-management, social support, the meaning of life with a chronic disease, and the needs of patients. To implement a proper multidisciplinary approach in practice, we need to have a comprehensive view of the complexity of endometriosis patients' life and disease history. METHODS: Four focus group discussions were conducted between October 2014 and November 2015 by a team consisting of medical and psychological specialists. 21 women (age: 31.57; SD = 4.45) with surgical and histological confirmation of endometriosis were included in the study. Discussions were audiotaped and transcribed verbatim, and a 62,051-word corpus was analyzed using content analysis. RESULTS: Four main themes emerged from the analysis: (1) the impact of endometriosis on quality of life, (2) medical experiences, (3) complementary and alternative treatments, and (4) different coping strategies in disease management. All themes were interrelated and highly affected by a lack of information and uncertainty caused by endometriosis. A supporting doctor-patient relationship, active coping, and social support were identified as advantages over difficulties. Finding the positive meaning of life after accepting endometriosis increased the possibility of posttraumatic growth. Furthermore, women's needs were identified at all levels of the ecological approach to health promotion. CONCLUSIONS: Our results highlight the need for multidisciplinary healthcare programs and interventions to find solutions to the difficulties of women with endometriosis. To achieve this goal, a collaboration of professionals, psychologists, and support organizations is needed in the near future.

Trends in the prenatal diagnosis of trisomy 21 show younger maternal age and shift in the distribution of congenital heart disease over a 20-year period.

Prenatal testing has changed greatly over the past two decades, which may affect the diagnosis of congenital heart disease (CHD) in Down syndrome. The present study aimed to analyze changes in the prevalence and distribution of CHD diagnosed via ultrasonography and fetopathology in 462 fetuses with trisomy 21 between two consecutive 10-year periods (1999-2018), as well as the associations between CHDs, ultrasound markers, and extracardiac malformations. Overall, the frequency of cardiovascular malformations in trisomy 21 was 27.7 and 26.5%, and ultrasound identified 70 and 62% of CHDs during these periods. A profound increase in first-trimester ultrasound findings and associated anomalies with CHDs (ventricular septal defect, Tetralogy of Fallot) since 2009 were observed. Second-trimester nonstructural heart abnormalities were associated with ultrasound anomalies (74%) and major extracardiac malformations (42.9%). During both study periods, mothers carrying fetuses with CHD were significantly younger than those without CHD (p = 0.038, p = 0.009, respectively). Comparing the two 10-year periods, there were no changes in the prevalence and detection of CHDs. Trend analysis revealed that, although the frequency of CHD remained stable, the diagnostic spectrum had shifted between the study periods. Detection of nonstructural heart abnormalities necessitates detailed follow-up for cardiac/extracardiac malformations and chromosomal disorders.

Vitamin D Deficiency and Gender Alter Vasoconstrictor and Vasodilator Reactivity in Rat Carotid Artery.

The vitamin-D-sensitivity of the cardiovascular system may show gender differences. The prevalence of vitamin D (VD) deficiency (VDD) is high, and it alters cardiovascular function and increases the risk of stroke. Our aim was to investigate the vascular reactivity and histological changes of isolated carotid artery of female and male rats in response to different VD supplies. A total of 48 male and female Wistar rats were divided into four groups: female VD supplemented, female VDD, male VD supplemented, male VDD. The vascular function of isolated carotid artery segments was examined by wire myography. Both vitamin D deficiency and male gender resulted in increased phenylephrine-induced contraction. Acetylcholine-induced relaxation decreased in male rats independently from VD status. Inhibition of prostanoid signaling by indomethacin reduced contraction in females, but increased relaxation ability in male rats. Functional changes were accompanied by VDD and gender-specific histological alterations. Elastic fiber density was significantly decreased by VDD in female rats, but not in males. Smooth muscle actin and endothelial nitric oxide synthase levels were significantly lowered, but the thromboxane receptor was elevated in VDD males. Decreased nitrative stress was detected in both male groups independently from VD supply. The observed interactions between vitamin D deficiency and sex may play a role in the gender difference of cardiovascular risk.

Survival and early complications of preterm infants with birthweight less than 500 grams during a 10-year period in Hungary.

BACKGROUND: There are limited data available on the survival and early complications of preterm infants with less than 500 g birthweight. To estimate the outcomes for these infants, it is important for caregivers to be aware of perinatal factors that may affect survival. OBJECTIVES: We assessed the mortality and certain early complications of preterm infants born with less than 500 g in Hungary between 2006 and 2015. METHODS: We reviewed data of 486 infants from the database of the Hungarian Central Statistical Office and in parallel of 407 infants from the "NICU database." The study period was divided into two epochs: 2006-2010 and 2011-2015. RESULTS: The survival was 27.1% in the first epoch and 39.1% in the second epoch, and the incidence of early complications was slightly higher in the second epoch. In the surviving group (first and second epoch combined), gestational age (25.1 vs 23.7 weeks), birthweight (458 vs 447 g) antenatal steroid treatment (66.3% vs 52.3%), surfactant therapy (95.1% vs 84.3%), median Apgar scores (6 vs 3 and 8 vs 5 at 1 and 5 minutes, respectively) and proportion of caesarean delivery (89.3% versus 68.5%) were higher than in the non-surviving group (first and second epoch combined). The proportion of multiple births was lower in the surviving group (15.7% vs 33.4%). CONCLUSIONS: Survival of infants with less than 500 g improved between 2006-2010 and 2011-2015 in Hungary. The slightly higher occurrence of early complications might be associated with improving survival.

Maternal-related factors in the origin of isolated cleft palate-A population-based case-control study.

OBJECTS: Isolated cleft palate (CPO) is the rarest form of oral clefting affecting 1-25 per 10 000 newborns worldwide. There is increasing evidence for the different pathogenetic backgrounds of CPO and cleft lip with or without cleft palate. The role of environmental factors in the origin of non-syndromic and syndromic CPO is unclear in most patients. The aim of this study was to estimate possible maternal risk factors in the origin of CPO. SETTING AND SAMPLE POPULATION: The Hungarian Case-Control Surveillance of Congenital Abnormalities contains data of 32 345 birth defect cases and 57 231 control newborns. The study samples included 751 cases with isolated CPO, 1196 matched controls and 57 231 population controls. MATERIAL AND METHODS: Maternal diseases during pregnancy in cases and population controls were compared, and adjusted ORs with 95% CI were calculated in a multivariable unconditional logistic regression model. RESULTS: Beyond the well-known robust female excess (58.9%)-maternal smoking (OR with 95% CI: 2.34, 1.94-2.81) medically recorded maternal anaemia, threatened abortion and excessive vomiting in pregnancy were associated with a higher risk for CPO in the offspring. An elevated risk was found in Graves' disease (OR: 4.30, 1.74-10.62), epilepsy (OR: 4.64, 2.44-8.82), migraine (OR: 2.82, 1.18-6.76) and essential hypertension (OR: 2.33, 1.32-4.10). Among acute diseases common cold (OR: 4.94, 3.48-7.03), acute respiratory infections (OR: 4.20, 1.49-11.82), influenza (OR: 2.95, 1.75-4.95), pulpitis (OR: 7.85, 2.80-22.03), cholecystitis (OR: 3.15, 1.16-8.60), acute urinary tract infections (OR: 4.08, 2.22-7.49) and pelvic inflammatory diseases (OR: 3.93, 1.62-9.53) during pregnancy also were associated with an increased risk for developing CPO. CONCLUSION: The findings of this study suggest that maternal diseases and lifestyle factors during the first trimester play a significant role in the development of isolated cleft palate.

Oestrogen-free oral contraception with a 4 mg drospirenone-only pill: new data and a review of the literature.

Purpose: The contraceptive pill is an effective and safe method of preventing pregnancy. The progestins used for contraception either are components of a combined hormonal contraceptive (tablets, patches or vaginal rings) or are used alone in progestin-only formulations. Progestin-only contraceptives are available as daily oral preparations, subcutaneous or intramuscular injectables (every 1-3 months), subdermal implants (every 3-5 years) and intrauterine systems (every 3-5 years). Long-acting progestins are highly effective in typical use and have a very low risk profile and few contraindications.Material and Methods: A new progestin-only, oestrogen-free contraceptive, drospirenone, in a dosage of 4 mg/day in a 24/4 regimen, has received regulatory approval in the USA and the EU. The molecule has antigonadotropic, antimineralocorticoid, antiestrogenic and antiandrogenic properties.Results: The regimen was chosen to improve the bleeding profile; maintain plasma oestradiol levels at those of the early follicular phase, to avoid hypoestrogenism; and preserve efficacy even with a missed pill, as drospirenone has a half-life of 30-34 h.Conclusions: Clinical studies have shown good efficacy, very low cardiovascular side effects and a favourable bleeding pattern, as well as maintenance of ovulation inhibition after scheduled 24 h delays in pill intake.

[Biopsychosocially informed therapy of symptoms related to premature ovarian failure]. / Korai petefészek-kimerüléssel összefüggo tünetek bio-pszicho-szociális szemléletu kezelése.

The basic legal conditions for pursuing medical activities in Hungary require that psychologists be employed at certain somatic departments. In the Hungarian medical practice, however, attitudes recognizing the potential role of psychological factors in the course of diseases are not widely present. The modern psychosomatic approach to healing includes biological, psychological and social factors that may predispose one to, precipitate or perpetuate a medical condition. This case study of a 35-year-old woman reports on a therapy in which the symptoms were indicative of both premature ovarian failure and anxiety, influencing each other in a bidirectional way. Therapy also included interventions on physical (hormonal therapy, Jacobson's progressive relaxation technique) and psychological levels (cognitive behavioral interventions). This case management is an example for how physician-psychologist collaboration serves the best interests of patients. Orv Hetil. 2017; 158(36): 1432-1435.
