Birth Weight and the Development of Functional Gastrointestinal Disorders in Infants
Baldassarre, Maria Elisabetta,Di Mauro, Antonio,Salvatore, Silvia,Tafuri, Silvio,Bianchi, Francesco Paolo,Dattoli, Enzo,Morando, Lucia,Pensabene, Licia,Meneghin, Fabio,Dilillo, Dario,Mancini, Valentin The Korean Society of Pediatric Gastroenterology 2020 Pediatric gastroenterology, hepatology & nutrition Vol.23 No.4
Purpose: To assess the association between birth weight and the development of functional gastrointestinal disorders (FGIDs) in the first year of life. Methods: This is a secondary analysis of a prospective cohort multicenter study including neonates, consecutively enrolled at birth, and followed up for one year. At birth all infants were classified by birth weight as extremely low (ELBW), very low, or low when <1,000, <1,500, and <2,500 g, respectively, and by birth weight for gestational age as appropriate (AGA, weight in the 10-90th percentile), small (SGA, weight <10th percentile), and large (LGA, weight >90th percentile) for gestational age. FGIDs were classified according to the Rome III criteria and assessed at 1, 3, 6, and 12 months of life. Results: Among 1,152 newborns enrolled, 934 (81.1%) completed the study: 302 (32.3%) were preterm, 35 (3.7%) were ELBW, 104 (11.1%) were SGA, 782 (83.7%) were AGA, and 48 (5.1%) were LGA infants. Overall, throughout the first year of life, 718 (76.9%) reported at least one FGID. The proportion of infants presenting with at least one FGID was significantly higher in ELBW (97%) compared to LBW (74%) (p=0.01) and in LGA (85.4%) and SGA (85.6%) compared to AGA (75.2%) (p=0.0001). On multivariate analysis, SGA was significantly associated with infantile colic. Conclusion: We observed an increased risk of FGIDs in ELBW, SGA, and LGA neonates. Our results suggest that prenatal factors determining birth weight may influence the development of FGIDs in infants. Understanding the role of all potential risk factors may provide new insights and targeted approaches for FGIDs.

Towards a digital twin realization of the blade system design study wind turbine blade
Alessandro Baldassarre,Alessandro Ceruti,Daniel N. Valyou,Pier Marzocca 한국풍공학회 2019 Wind and Structures, An International Journal (WAS Vol.28 No.5
This paper describes the application of a novel virtual prototyping methodology to wind turbine blade design. Numeric modelling data and experimental data about turbine blade geometry and structural/dynamical behaviour are combined to obtain an affordable digital twin model useful in reducing the undesirable uncertainties during the entire turbine lifecycle. Moreover, this model can be used to track and predict blade structural changes, due for example to structural damage, and to assess its remaining life. A new interactive and recursive process is proposed. It includes CAD geometry generation and finite element analyses, combined with experimental data gathered from the structural testing of a new generation wind turbine blade. The goal of the research is to show how the unique features of a complex wind turbine blade are considered in the virtual model updating process, fully exploiting the computational capabilities available to the designer in modern engineering. A composite Sandia National Laboratories Blade System Design Study (BSDS) turbine blade is used to exemplify the proposed process. Static, modal and fatigue experimental testing are conducted at Clarkson University Blade Test Facility. A digital model was created and updated to conform to all the information available from experimental testing. When an updated virtual digital model is available the performance of the blade during operation can be assessed with higher confidence.

Synchronization of estrus and ovulation are of paramountimportance in modern livestock improvement programs. These methods are critical for assisted reproductiontechnologies, including artificial insemination and embryotransfer, that can increase productivity. In the current study,subcutaneous implants containing norgestomet were placedfor long (14 days), medium (9 days), and short (5 days)periods of time in 70 crossbred ewes undergoing fixed-timeartificial insemination. The resulting effects on estrussynchronization and conception rates were subsequentlyevaluated. Among the synchronized ewes, 85.7% (60/70)underwent estrus over a period of 72 h after progestagentreatment ceased. The shortest mean interval betweenwithdrawal of the device and onset of estrus (34.2 ± 8.9 h) wasobserved in the G14 days of P4 group (p < 0.05). Theconception rate of the G14 days of P4 group was statisticallyhigher than that of the other groups (83.3% vs. 60.9% vs. 47.8%; p < 0.05). In conclusion, 14 days of norgestomettreatment produced higher conception rates and a greaternumber of pregnancies at the beginning of the breeding season.
