Cholesterol at ages 6, 12 and 24 months: Tracking and associations with diet and maternal cholesterol in the Infant Cholesterol Study
Øyri et al.
The finding, in our words
Home-based dried blood spot sampling from infants showed significant tracking of total cholesterol between 6 and 12 months of age. With 21% of children having elevated cholesterol, this demonstrates that decentralised microsampling can identify those needing early preventive measures.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
A study of 292 patients found that the slopes of home-collected stimulated dried blood spot C-peptide levels over six months predicted 12-month venous mixed-meal tolerance test results, P<0.001. This shows decentralised microsampling can monitor beta-cell function, though further validation is required to confirm its reliability and broader applicability.
In an adolescent with cerebral palsy undergoing a home-based, remotely supervised sprint-intensity interval training intervention, dried blood spot testing demonstrated a 37.8% reduction in triglycerides and a 15.4% improvement in total cholesterol to HDL ratio. This illustrates how remote microsampling can support decentralized metabolic monitoring in pediatric disability rehabilitation.
Home dried blood spot monitoring for maple syrup urine disease raised the proportion of leucine concentrations meeting therapeutic targets by 35 per cent. More frequent self-sampling at home was associated with better biochemical control in newborns and fewer hospital visits, showing that patient-centric microsampling can improve management of inherited metabolic disorders.
Home-collected dried blood spots from 143 infants aged 8-14 months revealed wide variation in total cholesterol (4.1 mmol/L, range 2.3-6.6) and glycated haemoglobin (4.9%, range 3.7-6.0). Infant cholesterol correlated with macronutrient intake and maternal cholesterol, supporting decentralised paediatric screening.
Isoelectric focusing from dried blood spot and capillary samples yields results identical to serum for transferrin glycosylation, with stable storage at -20 degrees Celsius for more than six months, enabling reliable diagnosis and therapy control of congenital disorders of glycosylation and supporting home self-collection for follow-up.
