Article Synopsis
  • A new type of tumor called keratin-positive giant-cell rich tumor has been identified, which is associated with certain genetic fusions and displays unique immunoreactivity to keratin in its cells.
  • Researchers investigated if similar keratin-positive tumors could occur in the jaws by studying 16 cases of giant cell granulomas, but found no evidence of keratin positivity in these cases.
  • Although no keratin-positive giant cell-rich tumors were detected in the jaw samples, the authors suggest that further research is needed, and oral pathologists should remain vigilant for the possible occurrence of this condition.

Background: Using Patient Reported Outcome Measures (PROMs) in clinical settings can improve patient outcomes by enhancing communication between patient and provider. There has been significant improvements in the development of PROMs, their implementation in routine patient clinical care, training physicians and other healthcare providers to interpret the PROMs results to identify any issues reported by the patient, and to use the PROMs results to provide or modify the treatment.

Main Body: Despite the increased use of PROMs, the lack of PROM completion by patients is a major concern in the optimal use of PROMs.

Background: The World Health Organization stresses the need for tailored COVID-19 models of vaccination to meet the needs of diverse populations and ultimately reach high rates of vaccination. However, little evidence exists on how COVID-19 models of vaccination operated in the novel context of the pandemic, how vulnerable populations, such as refugees, experience COVID-19 vaccination systems in high-income countries, and what lessons may be learned from vaccination efforts with vulnerable populations. To address this gap, this study explored COVID-19 vaccine delivery models available to newcomer refugees and immigrants, and refugee experiences across different COVID-19 vaccine delivery models in Calgary, Canada, and surrounding area in 2021 and 2022, to understand the barriers, strengths, and strategies of models to support access to COVID-19 vaccination for newcomer refugees and immigrants.

Background: Substitute decision-makers (SDMs) make decisions that honor medical, personal, and end-of-life wishes for older adults who have lost capacity, including those with dementia. However, SDMs often lack support, information, and problem-solving tools required to make decisions and can suffer with negative emotional, relationship, and financial impacts. The need for adaptable supports has been identified in prior meta-analyses.

Refugee decisions to vaccinate for COVID-19 are a complex interplay of factors which include individual perceptions, access barriers, trust, and COVID-19 specific factors, which contribute to lower vaccine uptake. To address this, the WHO calls for localized solutions to increase COVID-19 vaccine uptake for refugees and evidence to inform future vaccination efforts. However, limited evidence engages directly with refugees about their experiences with COVID-19 vaccinations.
