Growth

The NEST study is a prospective, observational research study designed to collect clinical measurements and image data to develop and evaluate artificial intelligence (AI)-derived algorithms for estimating anthropometric parameters in neonates and young infants. The study focuses on infants from birth up to 6 months of age and aims to assess the accuracy of AI-based estimations of length, weight, and head circumference using photographs and/or video recordings captured during routine clinical care. These AI-derived measurements will be compared against standard clinical measurements obtained by trained healthcare professionals in neonatal and infant care settings.

This is a research study to compare an investigational infant formula against a currently marketed infant formula. An investigational infant formula is one that has never been approved by the United States Food and Drug Administration (FDA). The purpose of this research study is to evaluate the growth and tolerance of infants who consume a new (not yet available to buy) extensively hydrolyzed cow milk protein infant formula compared to an extensively hydrolyzed cow milk protein infant formula that is currently available to buy. The study will also look at the growth of your baby, how many poops your baby has, what the poops are like (for example, soft or hard), how much study formula your baby drinks, how well your baby handles the study formula (such as spit-up, fussiness, gas, colic, or changes in sleep), and any health problems that might come up during the study.

The main purpose of the study is to evaluate the effect of early human milk fortification versus delayed fortification on growth and feeding tolerance in premature infants.

The association between nutrition in early life and its long-term health consequences has long been known. However, there is a scarcity of scientific evidence on how nutritional status affects child growth and development in remote, rural agro-pastoral communities with distinct dietary intake habits, geographical location, socio-economic status, and cultures.

Multi-center, single-blinded, randomized, controlled study consisting of two arms, to investigate the impact of an oral nutritional supplement in combination with dietary counseling on growth in children with growth concerns as compared to children who receive dietary counselling alone

The investigators of this clinical trial aim to: * Compare the effectiveness and efficiency of Clark's Twin Block Appliance (CTB) vs Carriere Motion Appliance (CMA) in correcting Class II malocclusion when used in post-pubertal older adolescents, in terms of skeletal and dental change. * Evaluate potential negative oral health-related quality of life (OHRQoL) impacts during the active treatment phase with either CTB or CMA in post-pubertal adolescents. * Investigate the impact of Class II malocclusion on oral health-related quality of life (OHRQoL) in post-pubertal adolescents. Class II division 1 malocclusion is a dental condition where the upper teeth protrude significantly over the lower teeth. It is a common type of malocclusion observed in orthodontic practice, accounting for approximately 20-25% globally. Correcting Class II malocclusion in growing patients using functional appliances and Class II correctors is relatively predictable. In Ireland and the United Kingdom, the Clark's Twin Block (CTB) is the most commonly used functional appliance. The CTB consists of two components: one for the upper teeth and one for the lower teeth. These components are engineered to position the lower jaw forward, thereby promoting the desired dentoskeletal changes (moving the upper teeth back and lower forward). Another device used for Class II correction is the Carriere Motion Appliance (CMA). The CMA is gaining popularity as a treatment option for Class II malocclusion, inducing dental changes similar to those achieved with a CTB. However, uncertainty persists regarding the effectiveness of these appliances in older adolescents in the post-pubertal growth phase (aged approximately 14.5 years or above). Additionally, although both CTB and CMA are effective in growing patients in correcting dental and skeletal discrepancies, they may influence daily activities, comfort, and psychological aspects, which often results in poor compliance. Poor adherence to orthodontic treatment, whether with fixed or removable appliances, can lead to higher rates of treatment failure.

This is a double-blind, randomized, multi-center, controlled, parallel study to evaluate the growth and tolerance of preterm infants fed human milk fortifier (HMF).

This is a multicenter randomised controlled trial to assess whether standardised enteral feeding in newborns with duct dependenty congenital heart disease decreases the risk of necrotising enterocolitis (NEC). The investigators plan to include a total 384 infants. The study will be carried out in three level III hospitals in Poland. The primary end will be NEC and/or death. Secondary end points include weight gain, hospital length of stay, time required to reach full feeding.
