Pressure and tidal volume delivery in extremely preterm infants at birth using different t-piece resuscitation devices

Infants <28 weeks' gestation in need of inflations at birth were recorded with Respiratory Function Monitor. Two devices were used for resuscitation. Peak Inspiratory Pressure spikes were visible in all inflations with GE Panda and in none with Neo-Puff. There was no significant difference in mean Vte/kg between GE Panda and Neo-Puff.

Nutritional problems of children with bronchopulmonary dysplasia after hospital discharge

The last decades have seen significant improvements in the care of premature infants. The introduction of new approaches, especially in the ventilatory management, have led to significant increase of survival rate of low and extremely low gestational age infants. These populations of neonates, however, often experience prolonged mechanical ventilation, which is widely recognized to be closely related to bronchopulmonary dysplasia (BPD) development. The management of BPD, which is a multifacto...

Functional nutrients in infants born by vaginal delivery or caesarean section

The development of a proper neonatal microbiota is of great importance, especially for the effects that dysbiosis has in acute and chronic diseases’ onset. The microbiota, particularly the intestinal one, plays a crucial role in maintaining the health of the host, preventing colonization by pathogenic bacteria and significantly influencing the development and maturation of a normal gastrointestinal mucosal immunity. Several factors may interfere with the physiological development of microbiot...

Victim’s identification and social categorization: first- and second-order effects on altruistic behavior

We explore in laboratory how donations to a charity can be influenced by the identifiability and the social categorization of the recipients. We find that donors give more, on average, to unidentified than to identified beneficiaries, since the latter are more likely to receive small donations than the former. Average donations are the same for in- and out-group beneficiaries; however, an in-group recipient is more likely to receive a top donation than an out-group one, whereas the latter is ...

Palladium-Catalyzed/Mn(OAc)3-Mediated 1,2-Diazidation and 1,2-Acetoxy/Hydroxylation of N-Allyl Sulfonamides

Palladium-catalyzed conditions for diazidation or acetoxy/hydroxylation of N-allyl sulfonamides by using Pd(OAc)(2) as the catalyst combined with Mn(OAc)(3) & sdot; 2H(2)O have been developed. The 1,2-diazidation reaction of the carbon-carbon double bond occurs in mild conditions (i. e. NaN3 as azide source in THF at room temperature), whereas the 1,2-acetoxy/hydroxylation requires an excess of Mn(OAc)(3) & sdot; 2H(2)O. The well-known ability of this reagent to act through single-ele...
