Objective This study aimed to investigate allied health professionals' (AHPs') perspectives pre- and post-implementation of an electronic medical record (EMR) in a tertiary health service in Australia and examine factors influencing user acceptance. Methods Data were collected pre- and post-EMR implementation via cross-sectional online surveys based on the Unified Theory of Acceptance and Usage of Technology (UTAUT). All AHPs at a large tertiary hospital were invited to complete the surveys.

EDs in Singapore faced a surge of confirmed cases of COVID-19 patients, which stretched their resources. Here we describe how we adopted strategic changes using the identify-isolate-inform tool to improve the evaluation, treatment and management of COVID-19 patients.

However, the synthesis of unusual crystal phases of noble metals still remains a great challenge, making the construction of heterophase noble metal nanostructures difficult. Here, we report a one-pot wet-chemical synthesis of well-defined heterophase fcc-2H-fcc gold nanorods (fcc: face-centred cubic; 2H: hexagonal close-packed with stacking sequence of "AB") at mild conditions.

In particular, amorphous/crystalline heterophase nanostructures have exhibited some intriguing properties. Herein, the one-pot wet-chemical synthesis of two types of amorphous/crystalline heterophase PdCu nanosheets is reported, in which one is amorphous phase-dominant and the other one is crystalline phase-dominant.

Generally, biocompatible and nontoxic poly(ethylene glycol) surface modification (PEGylation) can enhance NLC stability, although this may impair drug delivery and NLC clearance. To attain RIPL-NLC steric stabilization without impairing function, pH-sensitive cleavable PEG (cPEG) was grafted onto RIPL-NLCs (cPEG-RIPL-NLCs).
View Article and Find Full Text PDFRSA 905, a rapidly solidified aluminum alloy, has been widely utilized in optical, automotive, and aerospace industries owing to its superior mechanical properties such as hardness and strength compared to conventional aluminum alloys. However, the surface finishing of RSA 905 to achieve submicron surface roughness is quite challenging and was rarely addressed. This paper presents an experimental and analytical study on magnetic field-assisted finishing (MFAF) of RSA 905 through a systematic investigation on surface integrity in relation to the MFAF process parameters.

The sugar sphere pellets were firstly layered with IDN and hypromellose and then coated with Eudragit RS (copolymers of acrylic and methacrylic acid esters), employed as a release modifier, using a fluid-bed coater. Solid-state characterizations using solid-state X-ray diffraction and differential scanning calorimeter indicated that the antispasmodic agent was homogeneously layered onto the pellets in an amorphous state.

Methods: NLCs were prepared using a solvent emulsification-evaporation method and the RIPL peptide was conjugated to the maleimide-derivatized NLCs via the thiol-maleimide reaction. Employing a fluorescent probe (DiI), in vitro target-selective intracellular uptake behaviors were observed using fluorescence microscopy and flow cytometry.
Study Design: Retrospective study.
Objective: To determine if there is an association between obstructive sleep apnoea (OSA) and blood pressure (BP) pattern or heart rate variability (HRV) in people with spinal cord injury (SCI).
Setting: A state-based spinal cord service in Victoria, Australia.
Study Design: Observational study.
Objectives: To quantify diurnal blood pressure (BP) patterns and nocturnal hypertension and to measure diurnal urine production in people with chronic spinal cord injury (SCI), compared with controls without SCI.
Setting: Chronic SCI population in the community in Victoria, Australia.
Nanostructured transition metal dichalcogenides (TMDs) are proven to be efficient and robust earth-abundant electrocatalysts to potentially replace precious platinum-based catalysts for the hydrogen evolution reaction (HER). However, the catalytic efficiency of reported TMD catalysts is still limited by their low-density active sites, low conductivity, and/or uncleaned surface. Herein, a general and facile method is reported for high-yield, large-scale production of water-dispersed, ultrasmall-sized, high-percentage 1T-phase, single-layer TMD nanodots with high-density active edge sites and clean surface, including MoS , WS , MoSe , Mo W S , and MoSSe, which exhibit much enhanced electrochemical HER performances as compared to their corresponding nanosheets.

NPs with a mean diameter of approximately 200 nm, a narrow size distribution, and capable of efficient drug encapsulation were prepared using an emulsification-solvent evaporation method. The stability of NPs was verified in water, phosphate buffered saline (PBS), and serum after 24-h incubation.

Reasons for this include the imprecision of blood pressure measurement, the complexity of assessing cardiovascular risk, and the need to use multiple agents to control blood pressure.
Objective: This article discusses clinical scenarios that force clinicians to make decisions about blood pressure measurement techniques and methods of treatment.
