RESUMO

OBJECTIVES: Cytomegalovirus (CMV) infection is a significant health concern affecting numerous expectant mothers across the globe. CMV is the leading cause of health problems and developmental delays among infected infants. Notably, this study examines CMV infection in pregnancy, its management, prevention mechanisms, and treatment options. METHODS: Specifically, information from the Cochrane Library, PUBMED, Wiley Online, Science Direct, and Taylor Francis databases were reviewed along with additional records identified through the register, the Google Scholar search engine. Based on the search, 21 articles were identified for systematic review. RESULTS: A total of six randomized controlled trials (RCTs) were utilized for a meta-analytic review. As heterogeneity was substantial, the random effects model was used for meta-analysis. Utilizing the random-effects model, the restricted maximum likelihood (REML) approach, the estimate of effect size (d = -0.479, 95% CI = -0.977 to 0.019, p = 0.060) suggests the results are not statistically significant, so it cannot be inferred that the prevention methods used were effective, despite an inverse relationship between treatment and number of infected cases. The findings indicated that several techniques are used to prevent, diagnose, and manage CMV infection during pregnancy, including proper hygiene, ultrasound examination (US), magnetic resonance imaging (MRI), amniocentesis, viremia, hyperimmunoglobulin (HIG), and valacyclovir (VACV). CONCLUSIONS: The current review has significant implications for addressing CMV infection in pregnancy. Specifically, it provides valuable findings on contemporary management interventions to prevent and treat CMV infection among expectant mothers. Therefore, it allows relevant stakeholders to address these critical health concerns and understand the effectiveness of the proposed prevention and treatment options.

RESUMO

BACKGROUND: congenital cytomegalovirus (cCMV) infection during pregnancy is a significant risk factor for fetal and neonatal morbidity and mortality. CMV detection is based on the traditional ultrasound (US) and MRI (magnetic resonance) approach. METHODS: the present review used the PRISMA protocol for identification of studies associated with CMV infection and sonographic analysis. Various search terms were created using keywords which were used to identify references from Medline, Pubmed, PsycInfo, Scopus and Web of Science. RESULTS: sonographic analysis of the cCMV infection identified several of the key features associated with fetuses. The presence of abnormal patterns of periventricular echogenicity, ventriculomegaly and intraparenchymal calcifications is indicative of CMV infection in the fetus. Hyperechogenic bowels were seen frequently. These results correlate well with MRI data, especially when targeted transvaginal fetal neurosonography was carried out. CONCLUSIONS: ultrasonography is a reliable indicator of fetal anomalies, due to cCMV. Fetal brain and organ changes are conclusive indications of infection, but many of the ultrasonographic signs of fetal abnormality could be due to any viral infections; thus, further research is needed to demarcate CMV infection from others, based on the ultrasonographic approach. CMV infection should always be an indication for targeted fetal neurosonography, optimally by the transvaginal approach.

RESUMO

BACKGROUND: Despite advances in routine prenatal cytogenetic testing, most anomalous fetuses remain without a genetic diagnosis. Exome sequencing (ES) is a molecular technique that identifies sequence variants across protein-coding regions and is now increasingly used in clinical practice. Fetal phenotypes differ from postnatal and, therefore, prenatal ES interpretation requires a large amount of data deriving from prenatal testing. The aim of our study was to present initial results of the implementation of ES to prenatal diagnosis in Polish patients and to discuss its possible clinical impact on genetic counseling. METHODS: In this study we performed a retrospective review of all fetal samples referred to our laboratory for ES from cooperating centers between January 2017 and June 2021. RESULTS: During the study period 122 fetuses were subjected to ES at our institution. There were 52 abnormal ES results: 31 in the group of fetuses with a single organ system anomaly and 21 in the group of fetuses with multisystem anomalies. The difference between groups was not statistically significant. There were 57 different pathogenic or likely pathogenic variants reported in 33 different genes. The most common were missense variants. In 17 cases the molecular diagnosis had an actual clinical impact on subsequent pregnancies or other family members. CONCLUSIONS: Exome sequencing increases the detection rate in fetuses with structural anomalies and improves genetic counseling for both the affected couple and their relatives.

RESUMO

Nowadays, conscious planning of the family is very important for many people. The possibility of using protective measures against unplanned pregnancy is a great comfort. Most forms of contraceptives are intended for women, although their use can be ruled out in various health conditions. Scientists have been trying to develop a different type of method for men for many years. More and more research is being done and there have been promising results. It is hoped that soon both genders will have a similar range of contraceptive options to enable responsible family planning.

RESUMO

BACKGROUND: Posterior urethral valves (PUVs) account for 17% of pediatric renal failure. The management of pregnancies involving fetuses with PUV is hampered by the fact that current clinical parameters obtained from fetal ultrasound and/or fetal urine biochemistry are insufficient to predict postnatal renal function. We previously have developed a fetal urine peptide signature (12PUV) that predicted with high precision postnatal renal failure at 2 years of age in fetuses with PUV. Here, we evaluated the accuracy of this signature to predict postnatal renal outcome in fetuses with PUV in an independent single-center study. METHODS: Thirty-three women carrying fetuses with suspected PUV were included. Twenty-five fetuses received vesicoamniotic shunts during pregnancy. PUV was confirmed postnatally in 23 patients. Of those 23 fetuses, 2 were lost in follow-up. Four and 3 patients died in the pre- and perinatal periods, respectively. Follow-up renal function at 6 months of age was obtained for the remaining 14 patients. The primary outcome was early renal failure, defined by an eGFR < 60 mL/min/1.73 m2 before 6 months of age or pre- or perinatal death. RESULTS: The peptide signature predicted postnatal renal outcome in postnatally confirmed PUV fetuses with an AUC of 0.94 (95%CI 0.74-1.0) and an accuracy of 90% (95%CI 78-100). The signature predicted postnatal renal outcome for the suspected PUV cases with an AUC of 0.89 (95%CI 0.72-0.97) and an accuracy of 84% (95%CI 71-97). CONCLUSIONS: This single-center study confirms the predictive power of the previously identified 12PUV fetal urinary peptide signature.

RESUMO

OBJECTIVES: Prenatal interventions in LUTO (lower urinary tract obstruction) usually are still question of a debate between gynaecologist and paediatric nephrologist. We aimed the study to assess the early survival rate and renal outcome in LUTO foetuses. MATERIAL AND METHODS: The study was a prospective data analysis of 39 foetuses from singleton pregnancies. All pregnant women with LUTO in the foetus were qualified for VAS based on a local practice. The mean time of first urine analysis ranged between 13-30 weeks of pregnancy. Primary end-point analysis included live birth, 28d-survival, pulmonary and renal function assessment in neonatal period. RESULTS: From initial number of 39, six patients miscarried before the procedure was performed. Overall, 33 VAS were performer at the mean 21 week of pregnancy (range 14-30 weeks). 25/39 foetuses survived until delivery. Three neonates died in first 3 days of life. In the first month 3 children required peritoneal dialysis, but at 28 day all children were dialysis-free. Overall survival rate at 28 day was 56%. Renal function preservation of the initial group (39) turned out to be low - 18% (7/39). CONCLUSIONS: Our study showed average survival curves and complications. LUTO in the foetus had mostly unfavourable outcome in the neonatal period. The prenatal intervention did not increase it significantly and did not guarantee the preservation of normal kidney function.

RESUMO

Intrauterine growth restriction (IUGR) is one of the most important problems in current perinatology. The number of complications such as intrauterine fetal hypoxia, preterm and operative labours, intrauterine demises and neonatal deaths are signifcantly higher among pregnant women with IUGR. The proper monitoring and assesement of the fetal well-being are crucial to make the right decision about optimal time and mode of delivery.

RESUMO

OBJECTIVES: The aim of the study was to evaluate the efficiency of intrauterine treatment of large cysts in fetal lungs using thoracoamniotic shunts. MATERIAL AND METHODS: Our observational retrospective study was carried out on a series of 8 fetuses who under went thoracoamniotic shunting after sonographic statement of large macrocystic lesions in the lungs at the Department of Gynecology Fertility and Therapy of the Fetus, Polish Mother's Research Institute, between 2009-2014. RESULTS: Mean gestational age at shunt insertion was 26.6 (range 18-33) weeks. Marked mediastinal shift in the echocardiographic examination was observed in all of the investigated cases. Five fetuses had polyhydramion, with 4 hydropic cases. Out of the remaining 4 fetuses without impaired cardiac function, 3 had very large lesions at initial presentation and 1 had a lesion that was rapidly increasing in size. Shunt insertion was successful in all cases. Only one patient went into premature labor (at 36 weeks of gestation). Mean gestational age at delivery was 38.2 weeks. Cesarean section was necessary in the half of the patients due to obstetric complications. All newborns underwent resection of the lesions. Three of them were operated in the first month after birth. The rest of the operations were postponed. Prenatal diagnosis of congenital cystic adenomatoid malformations was confirmed by pathologists in all cases. CONCLUSION: Intrauterine therapy of macrocystic lesions in fetal lungs enables to achieve good perinatal outcome It needs to be considered in every case of a fetus with developing impaired cardiac function.

RESUMO

We report 3 cases of prenatal diagnosis of premature constriction of the ductus arteriosus after maternal benzydamine hydrochloride therapy (3-mg lozenges) in third-trimester pregnancies. In each case, fetal echocardiography revealed a dilated, hypocontractile right ventricle with severe tricuspid regurgitation and constriction of the ductus arteriosus. Although the effect of indomethacin and other nonsteroidal anti-inflammatory drugs on prenatal ductal constriction is well known, readily available over-the-counter nonsteroidal anti-inflammatory drugs such as benzydamine can have an equally deleterious effect and are best avoided in the third trimester of pregnancy.

RESUMO

OBJECTIVE: The aim of the study was to establish optimal diagnostic and therapeutic scheme and to assess the efficacy of intrauterine therapy of hydrocephalus. MATERIAL AND METHODS: The study was carried out between 1992-2012 on the total of 222 fetuses with hydro- cephalus, using Orbis-Sigma and ACCU-Flow valves (168 cases) and Cook8 shunts, according to a strictly defined diagnostic and therapeutic scheme. RESULTS: In the first stage of the study (between 1992-2001), a total of 168 fetuses with prenatally diagnosed hydrocephalus received intrauterine therapy In 91.6% of the cases the therapy resulted in a decreased size of cerebral ventricles. The valve dislocated in 23 cases (13.6%). Preterm delivery occurred in 44% of the affected neonates. Severe mental impairment occurred in 17.76%, average in 36.8%, and slight in 32.9% of the infants. Normal mental development at the age of 3 was observed in 12.5% of the children. A total of 11.2% of chldren did not require further neurosurgical treatment. In the second stage of the study (between 2006-2012) after therapy the size of the right lateral cerebral ventricle decreased by 54.76% (average of27.54 mm to 12.46 mm) and the left lateral cerebral ventricle decreased by 53.12% (average of 26.41 mm to 12.38 mm) (p=0.0018). The maximum and minimum width of the cerebral cortex increased by 23.06% and 27% (average of 9.04 mm to 11.75 mm vs. 3.65 mm to 5 mm), respectively Early complications were observed in 22% of the cases: PROM (6), intrauterine fetal death (4), intrauterine infection (1), and premature detachment of the placenta (1). Average gestational age at delivery was 34 weeks, and 24% of the patients delivered at term. CONCLUSIONS: Implantation of ventriculoamniotic shunts proved to be an effective form of therapy resulting in normalization of intracranial pressure. In both stages of therapy reduction of ventricular size in patients with hydrocephalus and good neurological outcome (45.4% in I stage, 60% in II stage) were observed. In the second stage of therapy the size of lateral brain ventricles after fetal therapy was significantly lower (54%). A total of 18% of the neonates did not require neurosurgical treatment.

RESUMO

BACKGROUND: Twin to twin transfusion syndrome occurs in 15% of monochorionic twin pregnancies. Untreated, TTTS has been reported to have a mortality of nearly 100%. Two main therapies include serial amnioreduction and fetoscopic laser coagulation for the vascular anastomoses. OBJECTIVES: The aim of the project was to investigate the optimal diagnostic and therapeutic procedure in pregnancies complicated by TTTS. Additionally the study was supposed to compare non-invasive and invasive methods of treatment and to show antenatal and postnatal follow - up to 4 months of age. METHODS: 42 pregnant women with twin-to-twin transfusion syndrome were assigned to laser therapy using diode laser and 33 pregnant women underwent only several amnioreductions. Selected parameters characterizing the pregnancy were compared in both groups. RESULTS: In the amnioreduction group, the perinatal survival rate seven days after the delivery was 31.8%. The survival rate of at least one twin was 39.4%. As compared to the amnioreduction group, in the laser group the survival rate of at least one twin was observed in 31 cases (31/42) and it was equal to 74%. Neurological complications in the amninoreduction group were observed in 19% (4/21) of cases, in the laser group and in 5% (2/40) of neonates at 4 months of age. CONCLUSIONS: Currently the preferred and only method that addresses the cause of the disease is the endoscopic laser coagulation of anastomoses. Comparison of the two treatments shows better outcomes with higher survival rates and minor neurological defects in cases treated with laser coagulation.
