Introduction: Studies have demonstrated growth suppressive effects in case of use of inhaled corticosteroids therapy.
Objective: To assess growth velocity during 12 months of inhaled corticosteroids therapy in children with persistent asthma.
Methods: Measurements of height were performed in the study group including 109 children with mild and moderately severe, persistent asthma, after 12 month with low or medium doses of either beclomethasone dipropionate or fluticasone propionate. The results were compared with a control group including 71 children with asthma treated with montelukast or cromones.
Results: There were statistically significant differences between study group and controls concerning the growth velocity after 3 months of inhaled glucocorticoid therapy (GSI).
Conclusions: The velocity of growth was decreased in the study group compared to controls after 3 months of treatment, but the differences become unsignificant after 12 months of therapy.

Long-acting growth hormones (LAGHs) represent a significant advancement in the treatment of pediatric growth hormone deficiency (GHD), offering an alternative to daily recombinant human growth hormone (rhGH) therapy. Traditional rhGH treatments, while effective, require daily injections, often leading to poor adherence due to the frequency of dosing, injection pain, and difficulties with storage and travel. In contrast, LAGHs, such as somatrogon, somapacitan, and lonapegsomatropin, are designed for once-weekly administration, improving patient compliance and quality of life.

Understanding the kinematics of aerosol horizontal transport and vertical mixing near the surface, within the atmospheric boundary layer (ABL), and in the overlying free troposphere (FT) is critical for various applications, including air quality and weather forecasting, aviation, road safety, and dispersion modeling. Empirical evidence of aerosol mixing processes within the ABL during synoptic-scale events over arid and semiarid regions (i.e.

This study delves into the feasibility of leveraging quasi-static component (QSC) generation during primary Lamb wave propagation to discern subtle alterations in the interfacial properties of a two-layered plate. Unlike the second-harmonic generation of Lamb waves, QSC generation doesn't necessitate precise phase-velocity matching but rather requires an approximate matching of group velocities to ensure the emergence of cumulative growth effects. This unique characteristic empowers the QSC-based nonlinear ultrasonic method to effectively surmount the limitations associated with inherent dispersion and multimode traits of Lamb wave propagation.

Study Question: Does a human fallopian tube (HFT) organoid model offer a favourable apical environment for human sperm survival and motility?
Summary Answer: After differentiation, the apical compartment of a new HFT organoid model provides a favourable environment for sperm motility, which is better than commercial media.
What Is Known Already: HFTs are the site of major events that are crucial for achieving an ongoing pregnancy, such as gamete survival and competence, fertilization steps, and preimplantation embryo development. In order to better understand the tubal physiology and tubal factors involved in these reproductive functions, and to improve still suboptimal in vitro conditions for gamete preparation and embryo culture during IVF, we sought to develop an HFT organoid model from isolated adult stem cells to allow spermatozoa co-culture in the apical compartment.

Background: Meier-Gorlin syndrome (MGORS) is a rare autosomal inherited form of primordial dwarfism. Pathogenic variants in 13 genes involved in DNA replication initiation have been identified in this disease, but homozygous intronic variants have never been reported. Additionally, whether growth hormone (GH) treatment can increase the height of children with MGORS is unclear.
