Clinical trials

The aim of this study is to determine whether restricted fluid intake (135 ±5 mL/kg/day) compared to liberal fluid intake (165 ±5 mL/kg/day) from day 8 of life reduces the incidence of bronchopulmonary dysplasia (BPD) at 36 weeks postmenstrual age or prior death in preterm infants born \<30 weeks gestational age.

Plain Language Summary: Background Glucocorticoids are stress hormones produced by the human body to control inflammation and regulate the immune system. Cortisol is the most well-known example of a glucocorticoid. These stress hormones are essential for the bodys healthy functioning. To treat certain types of cancer, such as leukemia (blood cancer) in children, glucocorticoids are administered as medications in large quantities. This helps rapidly reduce the number of cancer cells in the body but also leads to the suppression of the body's natural glucocorticoid production, causing a deficiency. This deficiency can be particularly dangerous for children with leukemia, as their immune defenses are already weakened by chemotherapy, leading to an increased risk of infections. Moreover, the signs of glucocorticoid deficiency in children with leukemia are often indistinguishable from the side effects of chemotherapy, making the deficiency harder to detect. Objectives The aim of the study is to understand how frequently and for how long the body's natural glucocorticoid production is impaired in children treated for lymphoblastic leukemia and lymphoblastic lymphoma. Additionally, the goal is to identify which children are at particularly high risk. By gaining a better understanding, this study may help to improve the detection and treatment of glucocorticoid deficiency in children with blood cancer. Methods Regular low-dose ACTH tests will be conducted to assess the bodys natural glucocorticoid production during and after treatment. To avoid placing additional burden on children who are already heavily affected by the disease, these tests will only be performed when there is already a venous access established and the children are in the hospital for treatment reasons.

Electrical impedance tomography (EIT) enables assessment of regional lung ventilation at the bedside. EIT has been safely used in newborn infants to image intrathoracic lung volume patterns as early as from the first minute of life. This prospective single-centre observational study is to identify optimal PEEP in infants on respiratory support by measurements of EIT, FOT and SOPI.

This longitudinal, prospective, multicentre study is to monitor lung function prospectively in childhood cancer patients after diagnosis. The impact of cancer treatment on pulmonary dysfunction non-invasively using lung function, lung imaging and breath analysis as well as clinical symptoms using a questionnaire will be assessed at different time points.

This study is to investigate breath analysis (breath metabolomics) combined with established bioinformatic tools as a platform for companion diagnostics.

This study is to evaluate the efficacy of the digital health assistant (DHA) "Alex" in improving asthma control in asthmatic children and adolescents aged 10 to 19 compared to their baseline values. It is designed to track over a period of six consecutive months lung function parameters, lung inflammation, asthma symptoms and burden, medication adherence, and passively recorded nocturnal asthma symptoms and markers related to sleep quality. In Phase I (months 1-3), Digital Health Assistant (DHA) 's core functionality will be deployed. In Phase II (months 3-6), the platform will be augmented with lung-function-fluctuations analysis-informed therapeutic recommendations, allowing to quantify the incremental benefit of targeted decision support beyond the gamified DHA alone. An embedded qualitative study will be conducted to evaluate acceptability of and engagement with the DHA.

The aim of this multicentric, randomised, two-arms and single-blinded clinical trial is to prospectively evaluate OptiThyDose for Congenital hypothyroidism (CH) and Graves' disease (GD).

1. The primary objective is to improve the sensitivity of novel immunodiagnostic tests for detection of TB disease in children. 2. The secondary objective is to determine biomarkers that discriminate children with TB infection and disease.
