Identifying the critical physically demanding tasks performed by personal support workers in Canada.

Due to increased work demands, personal support workers (PSWs) are experiencing more work-related injuries. However, little is known about PSW work tasks and their corresponding physical demand. The purpose of this study was to identify critical tasks that are physically demanding and completed frequently as identified by PSWs. Additionally, we identified contextual factors (i.e., environmental-, situational-, patient-related) that influenced physical demands. We surveyed 443 community-based PSWs working in Canada who rated the physical demand associated with client care tasks and identified contextual factors that can increase task specific physical demands. Transferring/repositioning patients, dressing, and bathing were perceived as most demanding. Patient weight and mobility influenced the level of physical demand required for most tasks. These data provide a foundation to develop physical employment standards and task specific education and training to prevent PSW injuries.

The Antibacterial and Remineralizing Effects of Biomaterials Combined with DMAHDM Nanocomposite: A Systematic Review.

Researchers have developed novel nanocomposites that incorporate additional biomaterials with dimethylaminohexadecyl methacrylate (DMAHDM) in order to reduce secondary caries. The aim of this review was to summarize the current literature and assess the synergistic antibacterial and remineralizing effects that may contribute to the prevention of secondary caries. An electronic search was undertaken in MEDLINE using PubMed, Embase, Scopus, Web of Science and Cochrane databases. The initial search identified 954 papers. After the removal of duplicates and screening the titles and abstracts, 15 articles were eligible for this review. The amalgamation of 2-methacryloyloxyethyl phosphorylcholine (MPC) and silver nanoparticles (AgNPs) with DMAHDM resulted in increased antibacterial potency. The addition of nanoparticles of amorphous calcium phosphate (NACP) and polyamidoamine dendrimers (PAMAM) resulted in improved remineralization potential. Further clinical studies need to be planned to explore the antibacterial and remineralizing properties of these novel composites for clinical success.

Use of the Myocardial Performance Index in Decreased Fetal Movement Assessment: A Case-Control Study.

OBJECTIVES: To determine whether there are any fetal cardiac function changes, as measured by the myocardial performance index (MPI), in pregnancies complicated by decreased fetal movement (DFM). METHODS: We performed a prospective cross-sectional case-control study of 50 DFM and 50 uncomplicated third-trimester pregnancies matched within 2 gestational weeks. Routine ultrasound growth and well-being parameters as well as MPI were measured. Average MPI measurements and its component values were compared between the DFM and the control group, as were demographics, other ultrasound data, and perinatal outcomes. RESULTS: Average left MPI (LMPI) and right MPI (RMPI) was similar between groups (LMPI: 0.54 ± 0.08 [DFM], 0.53 ± 0.08 [controls], p = 0.76; RMPI: 0.60 ± 0.12 (DFM), 0.59 ± 0.11 [controls], p = 0.79). However, subgroup analysis of DFM fetuses with (n = 20) or without (n = 30) any adverse perinatal outcome demonstrated modestly higher average RMPI and LMPI in the adverse perinatal outcome group (RMPI: 0.64 ± 0.08 vs. 0.57 ± 0.13, p = 0.02; LMPI: 0.56 ± 0.07 vs. 0.52 ± 0.07, p = 0.052). CONCLUSION: The MPI did not demonstrate clinically usable differences between the overall DFM population and controls. However, higher LMPI and RMPI values in the exploratory subgroup of DFM fetuses with adverse perinatal outcomes may warrant further exploration of the MPI in DFM.

How parents perceive and feel about participation in community activities. The comparison between parents of preschoolers with and without Autism Spectrum Disorders.

The present study compared how parents of preschoolers with and without Autism Spectrum Disorders (ASD) perceived and felt about participation in community activities. A questionnaire survey was conducted with 380 Hong Kong parents of preschoolers with ASD and 214 Hong Kong parents of preschoolers without ASD. The two groups were not different in their willingness and frequency of participation in community activities. However, the psychological processes underneath their willingness were very different. Among the parents of preschoolers with ASD, their willingness was associated with how they perceived the difficulty and importance of the participation and what emotions they experienced during the activities. This pattern of association was not evident among the parents of preschoolers without ASD.
