Article Synopsis
  • Lewy body dementia includes two main forms: dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD), with no disease-modifying therapies currently available and limited FDA-approved treatments.
  • Cholinesterase inhibitors, like rivastigmine and donepezil, help improve cognitive symptoms, while levodopa can aid motor symptoms.
  • Research is ongoing, with trials focused on disease modification rather than just symptom relief; promising results from phase II trials, like neflamapimod, highlight the need for better biomarkers and outcome definitions in studies.

Background: Job satisfaction and retention of healthcare staff remains an ongoing issue in many health systems. Huddles have been endorsed as a mechanism to improve patient safety by improving teamwork, collaboration, and communication in teams.

Aim: This study aims to synthesises the literature to investigate the impact of huddles on job satisfaction, teamwork, and work engagement in multidisciplinary healthcare teams.

Traditional hierarchical leadership has been implicated in patient safety failings internationally. Given that healthcare is almost wholly delivered by multidisciplinary teams, there have been calls for a more collective and team-based approach to the sharing of leadership and responsibility for patient safety. Although encouraging a collective approach to accountability can improve the provision of high quality and safe care, there is a lack of knowledge of how to train teams to adopt collective leadership.

Background: Most outpatient orthopedic follow-up visits for patients who had total joint arthroplasty are routine among those with well-functioning implants. The technology and resources now exist to enable patient assessment without requiring attendance in hospital. We tested an electronic clinic for routine follow-up in a small cohort of arthroplasty patients.

Pacific sockeye salmon (Oncorhynchus nerka) can travel several hundred kilometers to reach native spawning grounds and fulfill semelparous reproduction. The dramatic changes in lipid reserves during upstream migration can greatly affect internal toxicokinetics of persistent organic pollutants (POPs) such as PCBs, PCDDs, and PCDFs. We measured lipid content changes and contaminant concentrations in tissues (liver, muscle, roe/gonads) and biomarker responses (ethoxyresorufin O-deethylase or EROD activity and CYP1A levels) in two Pacific sockeye salmon stocks sampled at several locations along their spawning migration in the Fraser River, British Columbia.

Objective: This paper details an observational study that estimates rates for wearing seat belts in rural Alberta and compares them with rates derived from a similar study conducted in 1999.

Method: Direct observations of drivers and front-seat passengers of 72,593 light-duty vehicles were carried out at 334 survey locations in communities with populations of fewer than 25,000, throughout northern, central and southern Alberta. In addition to seat belt use, information collected included vehicle type, gender of drivers and passengers and, at intersections controlled by a stop sign, whether or not the vehicle came to a complete stop.
