Strongly Fluorescent Blue-Emitting LaO: Bi Phosphor for Latent Fingerprint Detection.

Blue-emitting bismuth-doped lanthanum oxide (LaO: Bi) with various concentrations of Bi was synthesized using the sol-gel combustion method and used for visualization of latent fingerprints (LFPs). An X-ray diffraction (XRD) study revealed the hexagonal structure of the phosphors and total incorporation of the bismuth in the LaO matrix. Field Emission Scanning Electron Microscopy (FE-SEM) and Fourier Transform Infrared Spectroscopy (FTIR) were used to study the morphology and the relative vibrations of the synthesized samples.

Tapered-cuff Endotracheal Tube Does Not Prevent Early Postoperative Pneumonia Compared with Spherical-cuff Endotracheal Tube after Major Vascular Surgery: A Randomized Controlled Trial.

Background: Patients undergoing major vascular surgery often develop postoperative pneumonia that impacts their outcomes. Conflicting data exist concerning the potential benefit of tapered-shaped cuffs on tracheal sealing. The primary objective of this study was to assess the efficiency of a polyvinyl chloride tapered-cuff endotracheal tube at reducing the postoperative pneumonia rate after major vascular surgery.

First closed-loop goal directed fluid therapy during surgery: a pilot study.

Objective: Intraoperative haemodynamic optimization based on fluid management and stroke volume optimization (Goal Directed Fluid Therapy [GDFT]) can improve patients' postoperative outcome. We have described a closed-loop fluid management system based on stroke volume variation and stroke volume monitoring. The goal of this system is to apply GDFT protocols automatically.

[Aerobic bacteria associated with acute appendicitis in children].

Objective: The aim of the study was to determine the microbiological profile of acute appendicitis in children.

Study Design: Prospective descriptive study including children hospitalized for acute appendicitis.

Methods: A specimen of the appendice and the peritoneal exudates (if exists) was performed intraoperatively for aerobe bacteriological examination.
