Acetylcholinesterase activity and bone biochemical markers in premature and full-term neonates.

Background Almost 30% of the premature infants have low body weight and bone mineral density due to prematurity. There is no consensus of screening premature neonates for metabolic bone disease; therefore, it is important to investigate the use of bone biochemical parameters. Latest studies involved the activity of acetylcholinesterase as a mediator in bone remodeling.

Clinical-laboratory findings of bone metabolism in healthy premature and full-term neonates: preliminary results.

Premature infants are a major risk group for bone metabolic disorders. The purpose of this study is to clarify certain aspects of bone metabolism in healthy preterm and full-term neonates. Forty neonates (20 preterm and 20 full-term) were the material of the study.

Inside the "fragile" infant: pathophysiology, molecular background, risk factors and investigation of neonatal osteopenia.

Current research in bone mineral metabolism reveals many aspects of osteopenia occurred in premature infants. This review examines not only the pathophysiological and molecular mechanisms of newborn osteopenia but also the risk factors and investigation. Osteopenia of premature infants has increased incidence among other diseases of prematurity.

Is there a necessity for multiple doses of surfactant for respiratory distress syndrome of premature infants?

Both prophylactic and early surfactant (SF) replacement therapy reduce pulmonary complications and mortality in ventilated infants with respiratory distress syndrome (RDS). The effectiveness of one or more doses and the impact on morbidity and mortality of premature neonates with RDS need to be further clarified. The objective of this study was to investigate the necessity of repeated surfactant replacement therapy in premature infants ≤32 weeks of gestational age and the possibility of an underlying pathology.

Antifungal chemoprophylaxis in children and adolescents with haematological malignancies and following allogeneic haematopoietic stem cell transplantation: review of the literature and options for clinical practice.

Invasive opportunistic fungal infections are important causes of morbidity and mortality in children and adolescents with cancer or haematopoietic stem cell transplantation (HSCT). Difficulties in establishing the diagnosis continue to delay antifungal therapy, and this has been shown to adversely impact on survival. Apart from ongoing attempts to improve early recognition, effective chemoprophylaxis of invasive fungal infections remains a goal of high priority in populations with disease-related incidence rates of 10% or higher.
