Titanium dioxide nanoparticles - physicochemical characterization and cytotoxic risk.

Titanium dioxide (TiO) nanoparticles (NPs) are incorporated into numerous consumer products yet data as to potential adverse health effects remains inconclusive. In this paper we physically characterize 16 nanoforms of TiO from different manufacturers of different size, crystalline structure and with surface chemistry. Physical measurements of the particles were performed and compared with those provided by manufacturers revealing several discrepancies.

The use of premedication for intubating very low birth weight infants in the neonatal intensive care unit: Results of a national survey.

Objective: To explore barriers and perspectives of premedication use for non-emergent intubations of very low birth weight (VLBW) infants (less than 1,500 g).

Study Design: A cross-sectional, online survey was distributed from January to April 2023 to members of the American Academy of Pediatrics Section on Neonatal-Perinatal Medicine. Data was analyzed using descriptive statistics and chi-square tests.

How do we capture child and family goals? Examining the goal setting practices used by community-based allied health professionals.

Purpose: This study aimed to i) identify child and family goals reported in a community allied health service, ii) map goals to ICF domains, and iii) evaluate goal characteristics against child-centred and family-centred practice principles.

Methods: A retrospective study design was used to extract and analyse raw goal data documented for children and families accessing a community-based allied health service. ICF linking rules were used to map goals to the ICF domains.

Genotyped cluster investigations versus standard contact tracing: comparative impact on latent tuberculosis infection cascade of care in a low-incidence region.

Background: Cluster and contact investigations aim to identify and treat individuals with tuberculosis (TB) and latent TB infection (LTBI). Although genotyped cluster investigations may be superior to contact investigations in generating additional epidemiological links, this may not necessarily translate into reducing infections. Here, we investigated the impact of genotyped cluster investigations compared to standard contact investigations on the LTBI care cascade in a low incidence setting.

Luminescence Lifetime-Based Water Conductivity Sensing Using a Cationic Dextran-Supported Ru(II) Polypyridyl Complex.

Water conductivity sensing relies universally on electrical measurements, which are subject to corrosion of the electrodes and subsequent signal drift in prolonged in situ uses. Furthermore, they cannot provide contactless sensing or remote readout. To this end, a novel device for water conductivity monitoring has been developed by employing a microenvironment-sensitive ruthenium complex, [Ru(2,2'-bipyridine-4,4'-disulfonato)], embedded into a quaternary ammonium functionalized cross-linked polymer support.
