Aim: In view of the long-standing recognition that gross domestic product (GDP) does not capture the unremunerated work largely conducted by women upon which societal well-being depends, to discuss the implications for GDP of maternal, newborn, child and adolescent health (MNCAH), and its influences on health, well-being and prosperity across the life course and across generations. Methods: A wide-ranging discussion of the informal think-tank The Venice Forum was held over two days, with inputs from invited experts in person and online. Results: There was consensus that a strong case could be made for inclusion of unremunerated work largely conducted by women as a positive contribution to GDP in view of its impact on future health and prosperity, and conversely exclusion from GDP of outputs from industries which harm health. Conclusion: Taken with the current challenges from COVID, climate change and conflict, there is a compelling need to redefine economic progress through equitable models and metrics that incorporate short-/medium-/long-term societal value of activities that improve MNCAH.

(Strong-quality evidence; strong recommendation). In selected cases, extension of this period up to 34+6 weeks may be considered (Expert opinion). Optimal benefits are found in infants delivered within 7 days of corticosteroid administration. Even a single-dose administration should be given to women with imminent preterm birth, as this is likely to improve neurodevelopmental outcome (Moderate-quality evidence; conditional recommendation). Either betamethasone (12 mg administered intramuscularly twice, 24-hours apart) or dexamethasone (6 mg administered intramuscularly in four doses, 12-hours apart, or 12 mg administered intramuscularly twice, 24-hours apart), may be used (Moderate-quality evidence; Strong recommendation). Administration of two “all” doses is named a “course of corticosteroids”. Administration between 22+0 and 23+6 weeks should be considered when preterm birth is anticipated in the next seven days and active newborn life-support is indicated, taking into account parental wishes. Clear survival benefit has been observed in these cases, but the impact on short-term neurological and respiratory function, as well as long-term neurodevelopmental outcome is still unclear (Low/moderate-quality evidence; Weak recommendation). Administration between 34 + 0 and 34 + 6 weeks should only be offered to a few selected cases (Expert opinion). Administration between 35+0 and 36+6 weeks should be restricted to prospective randomized trials. Current evidence suggests that although corticosteroids reduce the incidence of transient tachypnea of the newborn, they do not affect the incidence of respiratory distress syndrome, and they increase neonatal hypoglycemia. Long-term safety data are lacking (Moderate quality evidence; Conditional recommendation). Administration in pregnancies beyond 37+0 weeks is not indicated, even for scheduled cesarean delivery, as current evidence does not suggest benefit and the long-term effects remain unknown (Low-quality evidence; Conditional recommendation). Administration should be given in twin pregnancies, with the same indication and doses as for singletons. However, existing evidence suggests that it should be reserved for pregnancies at high-risk of delivering within a 7-day interval (Low-quality evidence; Conditional recommendation). Maternal diabetes mellitus is not a contraindication to the use of antenatal corticosteroids (Moderate quality evidence; Strong recommendation). A single repeat course of corticosteroids can be considered in pregnancies at less than 34+0 weeks gestation, if the previous course was completed more than seven days earlier, and there is a renewed risk of imminent delivery (Low-quality evidence; Conditional recommendation).

This mini-narrative historical review presents views and recommendations of Ancient Greek and Byzantine physicians and philosophers, concerning the nutrition and lifestyle, collectively referred in antiquity as ‘diet’, of pregnant and breastfeeding women, and the nutrition of the foetus and neonate. Pregnant and breastfeeding women in these eras were cared for with regard to their nutrition and well-being, in addition to their clothing, physical exercise and mental health. A number of ancient scholars taught that the foetus was fed through the umbilical cord. Breastfeeding by mothers was warmly recommended, but wet nurses and baby bottles were also available. Relevant information is found in preserved texts of well-known antique physicians and philosophers, who had studied medicine, or discussed medical issues. ©2021 Foundation Acta Pædiatrica.

There is emerging evidence that economic crises may impact long-term health. Furthermore, adversity experienced by women and their offspring might be transmitted to next generations. The Developmental Origins of Health and Disease (DOHaD) approach emphasises the importance of early life events for the state of health and risk for disease later in life. In this review, we discuss current evidence on the possible impact of economic crises on offspring health through the DOHaD framework and highlight the importance of critical periods of development for future disease risk. Therefore, successful interventions should prioritise strategies that address early life risk factors.

In reference to my commentary (1), Kono et al (2) correctly distinguish between improvements in mortality and morbidity and lack of significant improvement in cognitive delay among three years old survivors, born at 22 gestational weeks and actively resuscitated during 2003-2012 in Japan. This clarification is well taken.

Pulmonary hypertension (PH) is associated with meta-inflammation related to obesity but the role of adipose tissue in PH pathogenesis is unknown. We hypothesized that adipose tissue-derived metabolic regulators are altered in human and experimental PH. We measured circulating levels of fatty acid binding protein 4 (FABP-4), fibroblast growth factor -21 (FGF-21), adiponectin, and the mRNA levels of FABP-4, FGF-21, and peroxisome proliferator-activated receptor γ (PPARγ) in lung tissue of patients with idiopathic PH and healthy controls. We also evaluated lung and adipose tissue expression of these mediators in the three most commonly used experimental rodent models of pulmonary hypertension. Circulating levels of FABP-4, FGF-21, and adiponectin were significantly elevated in PH patients compared to controls and the mRNA levels of these regulators and PPARγ were also significantly increased in human PH lungs and in the lungs of rats with experimental PH compared to controls. These findings were coupled with increased levels of adipose tissue mRNA of genes related to glucose uptake, glycolysis, tricarboxylic acid cycle, and fatty acid oxidation in experimental PH. Our results support that metabolic alterations in human PH are recapitulated in rodent models of the disease and suggest that adipose tissue may contribute to PH pathogenesis.

The human microbiome is crucial for regulating normal development, but the exact point when it is established remains unknown. A sterile placenta was traditionally considered a prerequisite for a healthy pregnancy, but studies have revealed that the placenta harbours microbial communities, even under normal conditions. However, reports have failed to provide evidence for the consistent presence of bacteria in the normal human placenta, challenging the in utero colonisation hypothesis. This mini review examines our understanding of the potential placental microbial colonisation in normal healthy pregnancies. This may impact the metabolic and immune functions of the growing foetus and have long-term consequences.
