Effect of Growth Hormone Therapy on Pubertal Timing: Systematic Review and Meta-analysis.

Introduction Recombinant human growth hormone (rhGH) therapy effectively increases height in various disorders of childhood growth. However, whether rhGH affects pubertal timing is unclear. We aimed to review systematically published evidence on the effect of rhGH on pubertal timing. Methods Embase, Medline, and Cochrane library databases were searched until December 2021 on randomized and non-randomized controlled studies of rhGH in children. Results Twenty-five articles (n=1,438 children) were identified describing 12 randomized and 13 non-randomized controlled studies in children with idiopathic short stature (ISS; 15 studies), small for gestational age (n=6 studies), chronic renal failure (n=3), Noonan syndrome (n=1), and growth hormone deficiency (n=1). Significant differences in the effects of rhGH on pubertal timing were found by clinical indication. Only among children with ISS, rhGH promoted earlier age at pubertal timing (mean difference=-0.46 years; 95% CI, -0.90 to -0.03; 9 studies; n total=402) or higher relative risk for pubertal onset during study follow-up (1.26; 95% CI, 1.03 to 1.54; 6 studies; n total=284). Conclusions Treatment with rhGH appears to promote earlier pubertal timing among children with ISS. Evidence was lacking in children with growth hormone deficiency due to the absence of studies with untreated controls

Assessment of Biobanking Knowledge and Attitudes towards Biospecimen Donation among Healthcare Providers in Saudi Arabia.

BACKGROUND: Biobanking is a critical cornerstone of the global shift towards precision medicine (PM). This transformation requires smooth and informed interaction between a range of stakeholders involved in the healthcare system. In Saudi Arabia, there is still insufficient awareness of the importance of biobanking and its potential benefits for patients, the healthcare system, and society as a whole. The purpose of this study was to determine the biobanking knowledge of Saudi healthcare providers and the potential factors that might influence their self-reported attitudes toward biospecimen donation and biobanking. METHODS: A cross-sectional study was conducted targeting 636 healthcare providers in Makkah province using a structured, self-administered questionnaire. RESULTS: The study had a response rate of 61%. The mean knowledge level about biobanks was 3.5 (±1.8) out of 7. About one-third of the participants were aware of the Human Genome Project (HGP) (35%) or the term "biobank" (34%). The mean rating of their attitude was 37.3 (±4.3) out of 55. Most participants (74%) had a positive attitude toward medical research. Job position, general health, previous blood tests, knowledge of biobanking, and attitudes toward biomedical research were significantly related and predictors of willingness to donate biospecimens (p < 0.05). However, concerns about biospecimen misuse and confidentiality were the main reasons for not donating biospecimens. CONCLUSIONS: This study has shown that healthcare providers mostly lack basic knowledge about HGP and biobanks and their roles and activities, and therefore are generally disinclined to actively participate in biospecimens' collection and management. It is recommended that medical trainees receive more education and awareness about biobanks and the latest personalized healthcare approaches to improve translational research outcomes and achieve precision medicine

Here, we tested the associations between appetitive traits and growth velocities from birth to childhood. Appetitive trait data were collected using the Children's Eating Behaviour Questionnaire (CEBQ) in 149 children from the Cambridge Baby Growth Study at age 9-17 years. These participants also provided anthropometric measurements during infancy (birth, 3, 12, 18, and 24 months) and childhood (5 to 11 years). Standardized growth velocities (in weight, length/height, BMI, and body fat percentage) for 0-3 months, 3-24 months, and 24 months to childhood were estimated using individual linear-spline models. Associations between each of the eight CEBQ traits and each growth velocity were tested in separate multilevel linear regression models, adjusted for sex, age at CEBQ completion, and the corresponding birth measurement (weight, length, BMI, or body fat percentage). The three food-approach traits (food responsiveness, enjoyment of food and emotional overeating) were positively associated with infancy and childhood growth velocities in weight, BMI, and body fat percentage. By contrast, only one of the food-avoidant traits, satiety responsiveness, was negatively associated with all growth velocities. Significant associations were mostly of similar magnitude across all age periods. These findings reveal a broadly consistent relationship between appetitive traits with gains in weight and adiposity throughout infancy and childhood.
