In Reply.— The major point raised by the letter of Rigo and Senterre is that the plasma threonine concentration should decrease with increasing gestational age in the groups with high threonine intake (>1,500 µmol/kg/day). These are the infants receiving a milk formula containing 3.0 g/100 mL of protein in one of our first studies.1 In our recent study on term infants2 the threonine intake in the formula-fed infants was <1,500 µmol/kg/day. Plasma threonine values in relation to gestational age from the first study are shown in the Table.

Abstract Background Congenital lobar emphysema (CLE) is a congenital pulmonary cystic disease, characterized by overinflation of the pulmonary lobe and compression of the surrounding areas. Most patients with symptoms need an urgent surgical intervention. Caution and alertness for CLE is required in cases of local emphysema on chest X-ray images of extremely premature infants with bronchopulmonary dysplasia (BPD). Case presentation Here, we report a case of premature infant with 27 + 4 weeks of gestational age who suddenly presented with severe respiratory distress at 60 days after birth. Chest X-ray and computed tomography (CT) indicated emphysema in the middle lobe of the right lung. The diagnosis of CLE was confirmed by histopathological examinations. Conclusions Although extremely premature infants have high-risk factors of bronchopulmonary dysplasia due to their small gestational age, alertness for CLE is necessary if local emphysema is present. Timely pulmonary CT scan and surgical interventions should be performed to avoid the delay of the diagnosis and treatment.

One hundred four healthy premature infants, of birth weight 1,000 to 1,800 gm, were fed one of five feedings: (1) human milk; (2) human milk plus 13 meq/l of sodium chloride; (3) human milk plus 13 meq/l of sodium chloride and 18 meq/l of potassium chloride; (4) a half-skimmed cows milk formula; and (5) a partially-skimmed vegetable oil, cows milk formula. The infants fed any of the three human milk formulas gained weight at a slower rate than the infants fed either of the two cows milk formulas. Infants whose diets were changed from unmodified human milk to the half-skimmed cows milk gained large amounts of weight, and at times were visibly edematous. Infants whose diets were changed from the human milks with added sodium chloride, to the half-skimmed cows milk, gained lesser amounts of weight and did not become edematous. The infants fed the two cows milk diets gained similar amounts of weight, although one diet provided 6.5 gm/kg/day, the other 3.1 gm/kg/day of protein.

The article by Redding and Pereira reports that a group of premature infants with RDS had lower mean serum thyroxine levels than a group of prematures "comparable by gestational age" who did not develop RDS and implies a possible causative effect. Table I of the article indicates that of the 40 prematures with RDS, 10 had a gestational age of less than 29 weeks, 10 had a gestational age of 30 to 33 weeks, and 20 had a gestational age of 34 to 37 weeks.

OBJECTIVE: Retinopathy of prematurity (ROP) is a severe morbidity that can lead to blindness in premature babies. Neonatal hyperglycemia has been related to the growth of ROP in a variety of studies. However, there aren't many observational trials to show whether hyperglycemia is linked to ROP in the absence of other comorbidities. The aim of this research was to see if hyperglycemia in premature babies is linked to ROP in a different way. STUDY DESIGN: Premature infants (<1500 g or⩽ 32 weeks gestational age) were enrolled in a prospective longitudinal cohort study. All demographic, clinical and laboratory data were collected. Bedside whole-blood glucose concentration was measured every 8 hours daily for rst 7 , days of live. For any glucose reading <50 or>150 mg dl 1 serum sample was sent to the laboratory for conrmation. Hyperglycemia was dened as any blood glucose level⩾ 150 mg dl − 1. ROP patients were compared with non-ROP patients in a bivariate analysis. Variables signicantly associated with ROP were studied in a logistic regression model. RESULT:Atotal of 100 patients were enrolled with gestational age <32weeks and birth weight <1500g. Forty-eight patients (48%) were identied with hyperglycemia. On eye examination, 30 cases (30%) had ROP (19 with stage 1, 10 with stage 2 and 1 with stage 3). There were more cases of ROPin the hyperglycemia group compared with the euglycemia group (45.83% vs 15.38%, P = 0.007). Patients who developed ROP had signicantly higher maximum and average glucose concentrations when compared with non-ROP patients. Multiple factors have been associated with ROP on bivariate analysis, including gestational age, exposure to oxygen, respiratory support and poor weight gain. However, in a logistic regression model including all signicant variables, average blood glucose in the rst week of life was the factor independently associated with ROPwith an odds ratio of: 1.77 (95% condence interval: 1.08 to 2.86), P= 0.024 CONCLUSION: In a prospective cohort study of premature infants, elevated average blood glucose concentrations in the rst week of life is an independent risk factor associated with the development of ROP.

Objective Novel coronavirus disease 2019 (COVID-19) is a disease associated with atypical pneumonia caused by the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). The first cases of COVID-19 were reported in Wuhan at the end of 2019. Transmission usually occurs via infected droplets and close personal contact; the possibility of vertical transmission is still under debate. This retrospective study aimed to analyze clinical characteristics of premature infants born to mothers with symptomatic COVID-19 disease. Study Design This case control study compared the clinical and laboratory data of 20 premature infants born to mothers infected with SARS-CoV-2 with sex and gestational age–matched historical controls. Results The median gestational age and birth weight in both groups were similar. Respiratory distress developed in 11 (55.5%) infants in study group and 19 (47.5%) infants in control group. Mechanical ventilation and endotracheal surfactant administration rates were similar. Median duration of hospitalization was 8.5 (2–76) days in study group and 12 days in historical controls. Real-time reverse-transcription polymerase chain reaction tests (RT-PCR) of nasopharyngeal swab samples for SARS-CoV-2 were found to be negative twice, in the first 24 hours and later at 24 to 48 hours of life. No neutropenia or thrombocytopenia was detected in the study group. Patent ductus arteriosus, bronchopulmonary dysplasia, and necrotizing enterocolitis rates were similar between groups. No mortality was observed in both groups. Conclusion To the best of our knowledge, this is one of the few studies evaluating the clinical outcomes of premature infants born to SARS-CoV-2 infected mothers. There was no evidence of vertical transmission of SARS-CoV-2 from symptomatic SARS-CoV-2-infected women to the neonate in our cohort. The neonatal outcomes also seem to be favorable with no mortality in preterm infants. Key Points

ObjectiveTo compare postdischarge growth, adiposity and metabolic outcomes of appropriate for gestational age (AGA) versus small for gestational age (SGA) premature infants fed an exclusive human milk (HM)-based diet in the neonatal intensive care unit.DesignPremature infants (birth weight ≤1250 g) fed an exclusive HM-based diet were examined at 12–15 months corrected gestational age (CGA) (visit 1) for anthropometrics, serum glucose and non-fasting insulin, and at 18–22 months CGA (visit 2) for body composition by dual-energy X-ray absorptiometry.ResultsOf 51 children, 33 were AGA and 18 were SGA at birth. The SGA group had weight gain (g/day) equal to AGA group during the follow-up period. SGA had a significantly greater body mass index (BMI) z-score gain from visit 1 to visit 2 (0.25±1.10 vs −0.21±0.84, p=0.02) reflecting catch-up growth. There were no significant differences in total fat mass (FM) and trunk FM between groups. SGA had significantly lower insulin level (5.0±3.7 vs 17.3±15.1 µU/mL, p=0.02) and homeostatic model of assessment-insulin resistance (1.1±0.9 vs 4.3±4.1, p=0.02). Although regional trunk FM correlated with insulin levels in SGA (r=0.893, p=0.04), they had lower insulin level compared with AGA and no difference in adiposity.ConclusionsSGA premature infants who received an exclusive HM-based diet exhibited greater catch-up growth without increased adiposity or elevated insulin resistance compared with AGA at 2 years of age. An exclusive HM-based diet may improve long-term body composition and metabolic outcomes of premature infants with ≤1250 g birth weight, specifically SGA.
