Background Homocysteine is associated with endothelial damage and hypertension. Increased plasma homocysteine levels are often accompanied by cardiovascular impairment, including hypertension. Small for gestational age children have been found to have morbidity and mortality in cardiovascular diseases.Objective To assess for a possible association between homocysteine level and blood pressure in small for gestational age children.Methods This observational study was undertaken from December 2011 to April 2012 in Prof. Dr. R. D. Kandou Hospital, Manado, North Sulawesi, on children who were born small for gestational age in year 2004-2005. Data was analyzed by T-test to compare homocysteine levels in small for gestational age and normal birth weight children. Regression analysis and simple coefficient test were used to assess for an association between homocysteine levels and blood pressure in children who were small for gestational age at birth.Results The mean homocysteine level in small for gestational age children was significantly higher than that of normal birth weight children (P<0.001). We observed no correlation between homocysteine level and systolic blood pressure in the small for gestational age group (r=0.151, P=0.189). However, there was a weak correlation between homocysteine level and diastolic blood pressure in the small for gestational age group (r=0.237, P=0.049).Conclusion Children who were small for gestational age at birth have significantly higher mean homocysteine level than that of normal birth weight children. Higher homocysteine levels are associated with higher diastolic blood pressure in children who were small for gestational age at birth.

Atypical coeliac disease in young children is frequently missed when it presents atypically as non-gastrointestinal presentations to different specialties. There was a greater delay (54 months) in establishing the diagnosis in those with atypical coeliac disease (p < 0.001). No difference was observed in the mode of delivery or duration of breast feeding, but significant difference was observed between gestational age at birth (p < 0.001). Most cases showed stunted growth and underweight. Irritability, anaemia, rickets, dermatitis herpetiformis, alopecia and intussusception were other common predictors of atypical coeliac disease. Because of a myriad spectrum of non-gastrointestinal symptoms, at any age with diverse presentation, a high index of suspicion is therefore required.

AbstractMaternal age is an established predictor of preterm birth independent of other recognized risk factors. The use of chronological age makes the assumption that individuals age at a similar rate. Therefore, it does not capture interindividual differences that may exist due to genetic background and environmental exposures. As a result, there is a need to identify biomarkers that more closely index the rate of cellular aging. One potential candidate is biological age (BA) estimated by the DNA methylome. This study investigated whether maternal BA, estimated in either early and/or late pregnancy, predicts gestational age at birth. BA was estimated from a genome-wide DNA methylation platform using the Horvath algorithm. Linear regression methods assessed the relationship between BA and pregnancy outcomes, including gestational age at birth and prenatal perceived stress, in a primary and replication cohort. Prenatal BA estimates from early pregnancy explained variance in gestational age at birth above and beyond the influence of other recognized preterm birth risk factors. Sensitivity analyses indicated that this signal was driven primarily by self-identified African American participants. This predictive relationship was sensitive to small variations in the BA estimation algorithm. Benefits and limitations of using BA in translational research and clinical applications for preterm birth are considered.
