Introduction: To conduct a systematic review and meta-analysis of the association between chorioamnionitis and respiratory outcomes of prematurely born children.
Content: Pubmed, Medline and Embase were searched for relevant studies. Studies were included if they assessed prematurely born children, who had been exposed to chorioamnionitis and had either lung function testing or assessment of wheeze or asthma following NICU discharge. Two reviewers independently screened the search results, applied inclusion criteria and assessed methodological quality. One reviewer extracted the data and these were checked by a second reviewer.
Summary: A total of 1,237 studies were identified, but only eight which included 35,000 infants, fulfilled the inclusion criteria. One study looked at both lung function results and wheeze or asthma in childhood. Four of five studies found an association between wheeze/asthma in childhood and exposure to chorioamnionitis: the overall Odds Ratio (OR) for developing wheeze/asthma in childhood was OR 1.71 (95 % CI: 1.55-1.89). Four studies looked at lung function in childhood, three of which showed no statistically significant association between chorioamnionitis exposure and altered lung function. One study found lower lung function in those exposed to chorioamnionitis and lower expiratory flows with increasing levels of chorioamnionitis (forced expiratory flow at 50 % of exhaled forced vital capacity (=FEF50) p=0.012, forced expiratory flow at 25-75 % of the forced vital capacity is exhaled (=FEF25-75) p=0.014).
Outlook: There was a significant association between chorioamnionitis and the development of wheeze or asthma in childhood, but overall not in impairment of lung function.
Objectives: To discuss the increasing visibility of non-binary individuals and inclusive policies and practices in assisted reproductive technologies (ART).
Methods: Comparison between traditional ART approach designed for binary genders and propose approach in non-binary individuals.
Results: Traditional ART services, designed for binary genders, must adapt to address the unique fertility needs of non-binary patients. This includes using gender-neutral language, providing comprehensive fertility assessments, and offering hormone therapy and fertility preservation options. Children of non-binary parents benefit from open communication about gender diversity, enhancing psychological well-being. Positive societal attitudes and inclusive environments in schools are crucial for preventing discrimination and promoting mental health. A systemic approach is required to make ART inclusive. This involves training staff, adjusting facilities, updating documentation, and advocating for supportive legislation. Addressing the reproductive needs of non-binary individuals ensures equitable access to care and supports their family-building goals.
Conclusions: Ensuring the well-being of children in non-binary families requires psychological support, inclusive healthcare, legal recognition, social support, and comprehensive education.
Objectives: Atenolol is a commonly used beta bloscker in non-pregnant women. Many providers are hesitant in prescribing atenolol in pregnancy because of a possible association with poor fetal growth. We aimed to assess the association between atenolol and the occurrence of small for gestational age neonates compared to other beta blockers, as described in the existing literature.
Methods: We used the meta-analytic method to generate a forest plot for risk ratios (RR) of small for gestational age in patients who used atenolol vs. other beta blockers. Statistical heterogeneity was assessed with the I2 statistic.
Results: Two studies were included, with a resultant RR of 1.94 [95 % confidence interval (CI) 1.60; 2.35]. A study by Duan et al. in 2018 noted the following rate of small for gestational age for each beta blocker use: 112/638 atenolol, 590/3,357 labetalol, 35/324 metoprolol, and 50/489 propranolol. A study by Tanaka et al. in 2016 noted the following rate of small for gestational age: 8/22 for propranolol, 2/12 for metoprolol, 2/6 for atenolol, 0/5 for bisoprolol. Heterogeneity (I2) was 0 %.
Conclusions: Our results suggested an elevated risk of small for gestational age associated with atenolol use in comparison to other beta blockers, specifically labetalol, propranolol, bisoprolol, and metoprolol.
Objectives: Fetal hypoxia due to placental dysfunction is the hallmark of fetal growth restriction (FGR). Preferential perfusion of the brain (brain-sparing effect), as a part of physiological placental cardiovascular compensatory mechanisms to hypoxia, in FGR was reported. Therefore, the correlation between vascular endothelial growth factor A (VEGF-A) protein expression in the FGR placentas and newborns' early neurological outcome was examined.
Methods: This study included 50 women with FGR complicated pregnancies and 30 uneventful pregnancies. Fetal hemodynamic parameters, neonatal acid-base status after delivery, placental pathohistology and VEGF-A expression were followed. Early neonatal morphological brain evaluation by ultrasound and functional evaluation of neurological status by Amiel - Tison Neurological Assessment at Term (ATNAT) were performed.
Results: VEGF-A protein expression level was significantly higher in the FGR placentas than normal term placentas (Fisher-Freeman-Halton's test, p≤0.001). No statistically significant correlation between placental VEGF-A expression and different prenatal and postnatal parameters was noticed. Whereas the alteration of an early neurological status assessed by ATNAT was found in 58 % of FGR newborns, morphological brain changes evaluated by UZV was noticed in 48 % of cases. No association between the level of placental VEGF-A expression and the early neurological deficits was found.
Conclusions: As far as we know this is the first study of a possible connection between VEGF-A protein expression in the FGR placentas and neonates' early neurological outcomes. The lack of correlation between the FGR placental VEGF-A expression and neonates' neurological outcome could indicate that optimal early neurodevelopment may take place due to compensatory mechanism not related to placental VEGF-A expression.
