Abstract Aims Preterm birth has been associated with elevated blood pressure early in life; however, hypertension risks from childhood into adulthood remain unclear. We conducted a large population-based study to examine gestational age at birth in relation to hypertension risks from childhood into adulthood. Methods and results A national cohort study was conducted of all 4 193 069 singleton live births in Sweden during 1973–2014, who were followed up for hypertension identified from nationwide inpatient and outpatient (specialty and primary care) diagnoses from any health care encounters through 2015 (maximum age 43 years; median 22.5). Cox regression was used to examine gestational age at birth in relation to hypertension risk while adjusting for other perinatal and maternal factors, and co-sibling analyses assessed the potential influence of unmeasured shared familial (genetic and/or environmental) factors. In 86.8 million person-years of follow-up, 62 424 (1.5%) persons were identified with hypertension (median age 29.8 years at diagnosis). Adjusted hazard ratios for new-onset hypertension at ages 18–29 years associated with preterm (<37 weeks) and extremely preterm (22–27 weeks) birth were 1.28 [95% confidence interval (CI), 1.21–1.36] and 2.45 (1.82–3.31), respectively, and at ages 30–43 years were 1.25 (1.18–1.31) and 1.68 (1.12–2.53), respectively, compared with full-term birth (39–41 weeks). These associations affected males and females similarly and appeared substantially related to shared genetic or environmental factors in families. Conclusions In this large national cohort, preterm birth was associated with increased risk of hypertension into early adulthood. Persons born prematurely may need early preventive evaluation and long-term monitoring for the development of hypertension.

<b><i>Introduction:</i></b> The Preterm Erythropoietin (Epo) Neuroprotection (PENUT) Trial sought to determine the safety and efficacy of early high-dose Epo as a potential neuroprotective treatment. We hypothesized that Epo would not increase the incidence or severity of retinopathy of prematurity (ROP). <b><i>Methods:</i></b> A total of 941 infants born between 24–0/7 and 27–6/7 weeks’ gestation were randomized to 1,000 U/kg Epo or placebo intravenously for 6 doses, followed by subcutaneous or sham injections of 400 U/kg Epo 3 times a week through 32 weeks post-menstrual age. In this secondary analysis of PENUT trial data, survivors were evaluated for ROP. A modified intention-to-treat approach was used to compare treatment groups. In addition, risk factors for ROP were evaluated using regression methods that account for multiples and allow for adjustment for treatment and gestational age at birth. <b><i>Results:</i></b> Of 845 subjects who underwent ROP examination, 503 were diagnosed with ROP with similar incidence and severity between treatment groups. Gestational age at birth, birth weight, prenatal magnesium sulfate, maternal antibiotic exposure, and presence of heart murmur at 2 weeks predicted the development of any ROP, while being on high-frequency oscillator or high-frequency jet ventilation (HFOV/HFJV) at 2 weeks predicted severe ROP. <b><i>Conclusion:</i></b> Early high-dose Epo followed by maintenance dosing through 32 weeks does not increase the risk of any or severe ROP in extremely low gestational age neonates. Gestational age, birth weight, maternal treatment with magnesium sulfate, antibiotic use during pregnancy, and presence of a heart murmur at 2 weeks were associated with increased risk of any ROP. Treatment with HFOV/HFJV was associated with an increased risk of severe ROP.

In recent years, a number of the studies of myokine irisin in adults and isolated in newborns have been carried out. The role of adipocytokines in the growth and development of the fetus and children has been shown.The aim of the study was to assess the levels of myokine irisin and adipocytokines in newborns small for gestational age at birth and to analyze the relationship between the parameters of the hormonal status of children and their mothers.49 newborns and their mothers were examined. Two groups were identified: group 1 (Gr1) – newborns small for gestational age (n = 24), group 2 (Gr2) – newborns appropriate for gestational age (n = 25). The levels of irisin and adipocytokines in the blood serum were determined by the enzyme immunoassay.Newborns small for gestational age had significantly lower levels of leptin and IGF-1 in the umbilical cord blood compared to children with physical development corresponding to the gestational age. There were no significant differences in the irisin content of cord blood serum in newborn Gr1 compared with Gr2. The presence of significant positive correlations between the level of irisin in the umbilical cord blood of newborns small for gestational age and the body weight at birth was established. In Gr1, a positive relationship was found between the irisin levels of mothers and newborns (r = 0.518, p = 0.028). The differences in the irisin content between the groups were established, taking into account the delivery mode (p = 0.0104).The revealed statistically significant differences in the concentrations of the analyzed metabolic markers in mother–child pairs, their relationship with clinical and anthropometric parameters substantiate the possibility of using irisin and adipocytokines as predictors in predicting the formation of metabolic disorders of infants small for gestational age.
