Lipoprotein(a) prevalence trends in Portuguese children and adolescents: a real-world perspective   (2,992 times)
Isabel Morais Ribeiro, Susete Vieira, Miguel Saraiva, Mónica Tavares, José Carlos Oliveira, Isabel Mangas Palma, Helena Ferreira Mansilha
Clin Exp Pediatr. 2025;68(12):1031-1040.   Published online November 24, 2025
Early lipid screening, including lipoprotein(a) (Lp(a)), in children/adolescents is key to identifying and managing dyslipidemia and reducing the risk of early-onset cardiovascular disease. This study shows that prevalence of elevated Lp(a) in high-risk Portuguese children is alarming, with over 30% at intermediate/high risk and nearly 1% at very high-risk (>430 nmol/L). Since Lp(a) is mostly genetically determined, one-time early screening in atrisk children is crucial for timely monitoring and prevention.

Ga Won Jeon
Clin Exp Pediatr. 2025;68(7):486-488.   Published online April 16, 2025
Intermittent sigh breaths during high-frequency oscillatory ventilation can improve ventilation and oxygenation by enhancing lung recruitment. Although research on this approach in newborn infants is limited, some published studies suggest that sigh breaths are generally applied at a rate of 2–3 breaths/min with an inspiratory time of 0.5–1 second and pressure of current mean airway pressure + 5 cmH2O (maximum, 30 cmH2O).

Question: What is the prevalence of HTN among adolescents enrolled in the TLGS according to 3 different accepted definitions (4th report, ESH, and AAP-CPG). Also, what is the ability of each of these definitions in predicting early adulthood CIMT, as a surrogate for cardiovascular disease events?
Finding: The highest and lowest prevalence of stage 1 HTN was observed with the AAP-CPG (17.7%) and ESH (8.8%), respectively. Similarly, the highest and lowest prevalence of stage 2 HTN was noted with the AAP-CPG (1.5%) and ESH (0.8%), respectively. The highest to lowest predictive abilities belonged to the 4th report, ESH, and AAP-CPG, respectively.
Meaning: Among the various definitions of pediatric HTN, the 4th report offered the best ability to predict a high CIMT during early adulthood, followed by the ESH and AAP-CPG.

Finding: Both the IM and SC GnRH stimulation tests demonstrated comparable times to peak luteinizing hormone levels.
Meaning: Clinicians may consider the IM route as a time-efficient alternative, as it offers similar diagnostic utility for central precocious puberty without compromising the detection of hypothalamic-pituitary-gonadal axis activation.

Adiposity rebound in early childhood: understanding body mass index percentiles and monitoring on growth charts to be healthy   (2,424 times)
Sochung Chung
Clin Exp Pediatr. 2026;69(4):301-303.   Published online April 1, 2026
Height, weight, and body mass index percentiles should be tracked in routine childhood health checkups to address the age of adiposity rebound in early childhood. Comprehensive interventional lifestyle counselling in primary practice after growth and nutritional status assessments might be an early, effective strategy for preventing obesity and decreasing the double burden of disease in later life. Therefore, there is an urgent need for a cooperative and supportive health care system.
