Serious complications in both mother and newborn arising as a result of fetal macrosomia indicate the need for early diagnosis and prevention. Unfortunately, current predictors, such as fetal biometry, fundal height, and amniotic fluid index, appear to be insufficient. Therefore, we decided to assess the predictive potential of interventricular septal thickness (IVST), as measured at ≥33 weeks of gestation. Two hundred and ninety-nine patients met the inclusion criteria: complete medical history including all necessary measurements—namely, IVST obtained by M-mode echocardiography, fetal biometry, and birth weight. The Statistica 13.1 PL software was used to generate the receiver operating curve. The optimal cut-off point (IVST of 4.7 mm) was selected using the Youden index method. The analysis of fetal biometry abnormalities resulted in 46.6% of macrosomia cases being correctly predicted; however, IVST analysis detected 71.4% of cases. IVST at ≥4.7 mm appears to have a higher sensitivity and negative predictive value (NPV) than routine ultrasound.

Antinatalism is an umbrella term for numerous moral dilemmas associated with procreation. In the past few years, the deterioration of environmental conditions, social difficulties, global worsening of people’s mental health, and pandemics have induced discussion about antinatalism. Therefore, we aimed to characterize antinatalists in the Polish population in terms of the frequency and description of the main reasons behind this phenomenon. The cross-sectional study was performed in the Polish population. An online, four-part survey was performed between 19 and 25 January 2022. The study group comprised 1240 respondents. Antinatalists (n = 472, 38%) were defined as people who do not have children and want to be childless in the future, whereas pronatalists (n = 768, 62%) consisted of people who want to have offspring in the future and/or already have children. The opinion that climate change is a significant reason not to have a child appeared twice as often among antinatalists. Additionally, the performed binary logistic regression model highlighted the importance of the fear of climate change as an independent factor facilitating an antinatalistic attitude. Regarding females, the following factors discouraging them from having a child were observed: fear of child’s congenital diseases, pregnancy complications, dissatisfaction with medical services, and fear of exacerbation of maternal chronic diseases. Anxiety, depression, and stress were not found to be statistically different between pro- and antinatalist groups. However, further analysis revealed that female antinatalists were significantly more depressive and anxious. Our study helps us to understand why, as mentioned beforehand, around 38% of respondents prefer to stay childless. In conclusion, antinatalism views have become relatively prevalent in society, and its reasons include environmental antinatalism and medical factors, including depression and anxiety. However, better access to medical services and changes in climate politics were not found to be significant factors in encouraging society to decide to have offspring.

Hypoplastic left heart syndrome (HLHS) and single ventricle (SV) remain a significant cause of cardiac deaths occurring in the first week of life. Their pathogenesis and seasonal frequency are still unknown. Therefore, we attempt to look at the genesis of the HLHS and SV in the context of territorial distribution as well as seasonality. A total of 193 fetuses diagnosed with HLHS and 92 with SV were selected. The frequency was analyzed depending on the year, calendar month, quarter and season (fall-winter vs. spring-summer). The spatial distribution of HLHS and SV in Poland was analyzed. We observed a statistically significant overrepresentation of HLHS formation frequency in March: 27 (14.00%) in comparison to a monthly median of 15 (IQR: 13.75–16.25; p = 0.039), as well as a significantly higher frequency of HLHS in 2007−2009: 65 cases (33.68%) in comparison to the annual mean of 13.79 ± 6.36 (p < 0.001). We noted a higher frequency of SV among parous with the last menstrual period reported in the fall/winter season of 58 vs. 34 in the spring/summer season (p = 0.014). The performed analysis also revealed significant SV overrepresentation in 2008: 11 cases (12.00%) in comparison to the annual mean of 6.57 ± 2.71 (p = 0.016). Every single case of HLHS was observed when the concentration of benzo(a)pyrene and/or PM10 exceeded the acceptable/target level. Our research indicates that both the season and the level of pollution are significant factors affecting the health of parous women and their offspring. The reason why HLHS and SV develop more frequently at certain times of the year remains unclear, therefore research on this topic should be continued, as well as on the effects of PM10 and benzo(a)pyrene exposure.

Introduction: The placental thickness (PTh) is an ultrasonographic measurement commonly used to assess the placenta. The study aimed to determine selected factors influencing PTh in 2D prenatal ultrasonographic examination. It might have a special value in difficult cases for interpretation when PTh is above or below the reference values.Material and methods: In this retrospective study, we analysed the results of foetal ECHO examination of 2833 foetuses performed between June 2016 and December 2019 in our single unit. 596 healthy foetuses older than 12 weeks of gestation from singleton pregnancies were enrolled in the study. The following parameters were used in the further analysis: placental implantation site, gestational age according to the last menstrual period (LMP) and foetal biometry (FB); maternal weight, height, and body mass index (BMI) at the time of examination; and PTh.Results: PTh was affected by its location: posterior 33 mm vs. anterior 30 mm (p < 0.001). Moreover, its thickness significantly correlated with gestational age according to FB (r = 0.386, p < 0.001), LMP (r = 0.369, p < 0.001), maternal weight (r = 0.192, p < 0.001), height (r = 0.125, p = 0.002), and BMI (r = 0.147, p < 0.001), but not with maternal age (r = 0.050, p = 0.219). A linear regression model based on these data explained the 16.38% variability of the tested subjects (p < 0.001).Conclusions: Our observations suggest that maternal weight correlated more strongly with PTh than maternal BMI. For PTh evaluation, it is important to pay attention to the placental implantation site – the posterior placenta was thicker than the anterior placenta. Moreover, PTh variability remains largely unknown; therefore, further research in this field is needed.

Long-term monitoring of a fetus with heart failure is an undeniable challenge for prenatal cardiology. Echocardiography is constrained by many fetal and maternal factors, and it is difficult to maintain the reproducibility of the measured and analyzed parameters. In our study, we presented the possibilities of using modern speckle tracking technology in combination with standard echocardiography parameters that may be insufficient or less sensitive in the context of monitoring life-threatening fetal conditions. Our analysis shows the superiority of the parameters used to assess fetal cardiac architecture, such as the GSI Global sphericity Index, and fetal cardiac function, such as the FAC fractional area change and the EF ejection fraction, which temporal change may indicate a worsening condition of the fetus with heart failure. The significant increase in the parameters of fetal heart size in speckle tracking allows for an improved echocardiographic diagnosis and monitoring of the fetus with heart failure and the prognostic conclusions about the clinical condition after birth. Significant decreases in FAC for the left and right ventricles and EF for the left ventricle may indicate an unfavourable prognosis for the monitored fetus due to heart failure.

Lymphangiomas are uncommon, benign (from a histopathology viewpoint) malformations of the lymphatic system with thin-walled vessels; however, these tumors may be dangerous for fetal or neonatal life. They are observed in 1:6000 newborns at birth and in 1:750 spontaneous abortions. We aimed to investigate the role of fetal echocardiography in the prognosis of lymphangioma. Selected data of 19,836 pregnant women studied between 1999 and 2020 were retrospectively analyzed. In total, 32 cases of lymphangioma meeting the following criteria were further analyzed: (1) ultrasound availability from the 1st trimester of pregnancy and (2) nuchal translucency ≤ 2.5 mm. Echocardiographic findings, karyotype, size, and location of the possible lesion were juxtaposed with the clinical follow-up. The statistical analysis was performed using Statistica 13.1 software (StatSoft, Tulsa, OK, USA). Lymphangioma in the analyzed material coexisted with abnormalities in fetal echo in 78% (n = 25) of cases, especially: heart defect in 50% (n = 16) and with normal heart structure with functional changes in 28% (n = 9). Karyotype was available in 50% of the analyzed cases (n = 16). Normal cytogenetic results were observed in 62.5% (n = 10) of cases. In the remaining cases, the following were observed: Turner Syndrome: 25% (n = 4) and Down Syndrome 12.5% (n = 2). The rate of alive newborns was significantly higher among fetuses with isolated lymphangioma in comparison to those with lymphangioma associated with abnormal ECHO examination: 38.46% (n = 5) vs. 15.38% (n = 2; p = 0.037). Abnormal ECHO exam was a poor prognostic sign for fetuses with lymphangioma; therefore, we think it is important to refer these cases for detailed echocardiography in tertiary centers. Moreover, it should be highlighted that in all lymphangioma cases there was an indication to perform the karyotype assessment, as there was a high risk of aneuploidy.
