Association between lesion depth and placement technique with failures requiring extraction of preformed metal crowns in primary molars. A retrospective study.

Purpose: The aim of the present study was to evaluate the factors associated with failure requiring extraction after placement of preformed metal crowns (PMCs) in primary molars. Radiographic caries depth at baseline (initial/moderate and severe) and placement technique (Conventional and Hall technique) and other patient-related variables were analysed.

Methods: Clinical and radiographic records from children aged 2-10 years who had at least one primary molar treated with PMCs between 2011 and 2019 were evaluated.

Experiences of participant and public involvement in an international randomized controlled trial for people living with dementia and their informal caregivers.

Background: This study was initiated and co-designed by a Participant and Public Involvement (PPI) group attached to HOMESIDE, a randomized controlled trial that investigated music and reading interventions for people living with dementia and their family caregivers across five countries: Australia, Germany, Norway, Poland, and the UK. The aim was to capture experiences of PPI across the five countries, explore the benefits and challenges of PPI in dementia research, and identify contributions made to the study.

Methods: We surveyed PPI members and academic researchers who collaborated on the HOMESIDE study.

Exploring why European primary care physicians sometimes do not think of, or act on, a possible cancer diagnosis. A qualitative study.

Background: While primary care physicians (PCPs) play a key role in cancer detection, they can find cancer diagnosis challenging, and some patients have considerable delays between presentation and onward referral.

Aim: To explore European PCPs' experiences and views on cases where they considered that they had been slow to think of, or act on, a possible cancer diagnosis.

Design & Setting: A multicentre European qualitative study, based on an online survey with open-ended questions, asking PCPs for their narratives about cases when they had missed a diagnosis of cancer.

Presence of (Phylotype I) in Aquatic Environments in the Netherlands.

, a European Union quarantine organism, was until recently absent in the aquatic environments and outdoor cultivation systems of the region. This bacterium was only sporadically reported in restricted greenhouse cultivation systems in some EU countries. In this paper, we report the first findings of (phylotype I) in surface water in two distinct geographic locations in the Netherlands in 2020.
