Objective: The use of umbilical artery catheters (UACs) for parenteral nutrition (PN) administration is controversial, and limited data exist on the safety of administration through this route. The objective of this research is to evaluate neonates who received PN through a UAC and assess catheter-related complications and PN composition.
Methods: This retrospective study evaluated all neonates who received PN through their UAC while admitted in the neonatal intensive care unit between January 2019 and December 2022.
Article Synopsis
- The study aimed to assess the experiences and challenges faced by AO Spine Fellows in Latin America, particularly those in their first three years of practice.
- A survey was conducted among recent AO Spine Associate Fellows, revealing that Argentina, Brazil, and Colombia have the highest participation, with most respondents being orthopedists aged 36-45.
- Findings indicate that while junior fellows feel confident in treating degenerative spine conditions and prefer the standard posterior technique, there is increasing interest in endoscopic and minimally invasive methods, highlighting areas for potential improvement in the fellowship program.
The sol-gel route was used to synthesize a series of compounds of the system Bi.Ba.Pr.
View Article and Find Full Text PDFTwiddler's syndrome is the voluntary or involuntary manipulation of an implanted device, most described in cardiac literature. Lead coiling may result in device malfunction due to lead migration or, less commonly, lead fracture. There are few but increasing reports of Twiddler's syndrome resulting in lead migration in sacral neuromodulation, but lead fracture has not yet been described.
