Objective: To assess volatile organic compounds (VOCs) in breath samples collected non-invasively from preterm and full-term infants.
Methods: This was a pilot study included preterm and full-term infants who were not intubated or suspected or diagnosed with metabolic or gastrointestinal disorders. The samples were analyzed for VOCs using a selected-ion flow-tube mass spectrometer.
Results: Twenty infants were included; ten preterm and ten full-term infants. Twenty-two VOCs were detected and measurable in all samples. There was a significant difference between preterm and full-term infants for the 2-propanol, acetaldehyde, acetone, acetonitrile, benzene, ethanol, isoprene, pentane, 3-methylhexane, 2-nonene, ethane, triethylamine, and trimethylamine compounds.
Conclusion: It is feasible to measure VOCs in breath samples of preterm and full-term non-intubated infants. Full-term infants express different concentrations than preterm infants. Further studies are needed to examine the utility and reproducibility of measuring VOCs to identify neonatal diseases and predict outcomes.

Foveal Avascular Zone development by OCTA: weighing the influence of Gestational Age and neonatal early growth independently of Retinopathy of Prematurity.

Pediatrics Department. Alvaro Cunqueiro University Hospital, 36313 Vigo, Spain. Galicia Sur Health Research Institute.
Purpose: Focusing the premature birth and its potential complications, this study analyzes Foveal Avascular Zone (FAZ) measured by Optical Coherence Tomography Angiography (OCTA) and its correlation with the severity of prematurity and neonatal growth.
Methods: A cross-sectional comparative study was performed, involving 71 children school-age with history of prematurity and a full-term children control group. Several variables from the neonatal period were collected, such as Gestational Age (GA), Birth Weight (BW), initial Weight Gain (WG) and Retinopathy of Prematurity (ROP).

Objective: To explore the clinical significance of trisomy 7 signaled by non-invasive prenatal testing (NIPT).
Methods: Pregnant women with high risk for trisomy 7 by NIPT from January 2017 to December 2023 were selected as the study subjects, and the results of prenatal diagnosis and follow-up were analyzed. Literature related to pregnant women with a high risk for trisomy 7 by NIPT from January 2016 to July 2024 was retrieved from China Biomedical Literature Database, Wanfang Database, China National Knowledge Infrastructure and PubMed database.
Background: Prematurely born individuals are usually of low or normal weight in childhood; in adulthood, however, their probability of being overweight is twice that of persons born at full term. There is not yet any way to predict the weight development of premature babies.
Methods: A polygenic BMI score (BMI = body-mass index), calculated from the often very small individual effects of more than 2 million genetic variants, was recently described for adults.
Factors Associated with the Prolonged Use of Donor Human Milk at the Da Nang Hospital for Women and Children in Vietnam.

Background And Objectives: Donor human milk (DHM) from a human milk bank (HMB) is used to feed low-birthweight (LBW) and preterm infants when mothers cannot provide their own breastmilk. The misuse of DHM could interfere with mothers' breastmilk and weaken breastfeeding efforts. This study aimed to identify factors behind prolonged DHM usage during the first six years of Vietnam's first HMB.

Children born with a very low birthweight (VLBW; <1500 g) and/or very preterm (VPT; <32 weeks) are at increased risk of mental health problems, but adult data are inconsistent. We examined the prevalence of a range of mental health disorders in a national cohort of adults born with a VLBW, as well as associations between gestational age and mental health outcomes. All infants born with a VLBW in New Zealand in 1986 were followed prospectively from birth.
