Background Hazardous alcohol use significantly affects health and wellbeing in society. General practitioners (GPs) are uniquely positioned to address this problem by integrating early identification and brief intervention (EIBI) in daily practice. Unfortunately, EIBI implementation remains low. Community-oriented strategies (COS), defined as public health activities directed to the general population, are suggested to address this implementation gap. COS aim to increase the understanding, engagement and empowerment within the population to facilitate EIBI delivery. However, no consensus on what COS should contain exists. Objectives To obtain insight in the stakeholders’ perspectives and create consensus with them on COS with the highest potential to facilitate EIBI delivery. Methods Four nominal group sessions were conducted with 31 stakeholders representing 12 different stakeholder groups from Leuven (Belgium). Stakeholders generated ideas, reflected on them in group and prioritised them anonymously, creating four separate lists. Merging these lists with their relative scores resulted in a master list, which was checked for accuracy through a member check. Qualitative content analysis on the stakeholder’s notes provided an in-depth exploration of their perspectives. Results Twenty-one strategies were identified, nine of which were COS. Highlighting the GPs’ proactive role was considered most relevant. Other foci included creating awareness on the effects of alcohol use and normalising discussing alcohol use within the community. A holistic approach, exceeding the sole focus on COS, combining community, healthcare and government was accentuated. Conclusion Stakeholders emphasise addressing the proactive role of GPs as most promising COS, though it should be delivered within a holistic multi-component approach.

BackgroundSeveral studies have investigated the histopathology of mechanically retrieved thrombi from stroke patients. Thrombi with unusual components constitute about 1–2% of all stroke thrombi in clinical practice. Knowledge about these rare components is limited.ObjectivesTo characterize the histopathology of unusual stroke thrombi from a real-world setting with relation to clinical presentation, patient characteristics and procedural aspects of mechanical thrombectomy.MethodsOne-thousand and eight thrombi retrieved from stroke patients with mechanical thrombectomy at three different hospitals were retrospectively reviewed for unusual histological components. Fifteen thrombi were included in the study for further histopathological analysis. Clinical data and data on procedural aspects were collected.ResultsWe identified six cases with large amounts of extracellular DNA, of which three were calcified. All six cases except one received anticoagulant therapy. We describe two types of calcifications that differ with respect to general calcification morphology, von Kossa staining pattern, macrophage immunophenotype and presence of multinucleated giant cells. Cholesterol-rich (n = 3), adipocyte-like pattern-rich (n = 2), collagen-rich (n = 2) and myxomatous (n = 1) thrombi were also identified and are discussed with regard to pathogenesis and clinical and intervention characteristics. Finally, a thrombus with parts of a vascular wall is described. Suggestions for future studies are made and clinical and technical aspects of the management for these rare but important patients are discussed.ConclusionIn our retrospective multicenter study, we characterized stroke thrombi histopathologically and found subgroups of thrombi defined by presence of rarely seen components. These defined subgroups showed relation to underlying cardiovascular disease, patient characteristics, and mechanical thrombectomy technique. Knowledge about these components may increase our understanding of stroke pathophysiology and influence interventional procedures.

Hazardous alcohol use is one of the leading risk factors for morbidity and mortality in the world. Early identification and brief interventions (EIBIs) delivered in primary care is an effective but underutilized strategy to address this issue. Community-oriented strategies (COS) are suggested to facilitate EIBI delivery. COS are public health activities directed to the general population raising awareness and encouraging behaviour change. Unfortunately, it remains unclear what these COS should comprise and what their added value might be in EIBI delivery. To map the available information on COS aiming to facilitate alcohol-related EIBI delivery in general practice. A scoping review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping reviews guidelines, was used to map both grey and peer-reviewed literature. Of the 6586 information sources screened, 8 sources were retained in this review. Three COS are currently described in the literature, all with their different components. They include the use of mass media, self-assessment tools and waiting room actions. Waiting room actions comprising audio recordings or computerized self-assessment tools significantly increase the discussion on alcohol use in primary care. The effect of mass media and community-wide self-assessment tools on EIBI delivery remains to be determined. Currently, the described COS lack empirical justification to motivate their added value in facilitating EIBI delivery. However, a theoretical reflection showed the use of a limited set of behaviour change techniques, which might support the use of COS. There remains a lot of possible strategies to explore. This review highlights the current evidence gap and discusses the next steps.
