Development of a systematic referral model to primary care health interventions for patients with atrial fibrillation. a delphi study

Abstract Background The European Society of Cardiology (ESC) guidelines for the management of atrial fibrillation (AF) recommend integrated care in AF, combining medical treatment with lifestyle modifications and psychosocial management in a multi-disciplinary set-up. Research show that patients with AF can benefit from lifestyle interventions and psychosocial management, like patient education. According to World Health Organization recommendations, these health interventions are moving from hospitals to primary healthcare settings. Therefore, patients with AF should be systematically referred to these interventions. Yet, an evidence-based referral model that can support this transition is lacking. Purpose The purpose is to develop a systematic referral model for primary care health interventions for patients with AF. Methods We used the Delphi-technique with three rounds of questionnaires (figure 1). International and national clinical experts in AF across disciplines and health sectors were invited to participate. In the first round, the expert panel evaluated items that could be part of a referral model on relevance, improvability and self-reporting. In the second round, the expert panel evaluated each item as either an inclusion or exclusion criteria, important knowledge to have, or not relevant. In the third round, the expert panel evaluated the items according to data source and outcome status. A final model was drawn based on items reaching consensus. The study was reported according to the guidance on conducting and reporting Delphi studies (CREDES). Results In total, 69 of 139 invited experts accepted to participate (50%). These were mostly academics or clinicians (90%), stemming from primary sector (16%), secondary sector (35%) and research (32%). Most were medical doctors (36%) and nurses (35%). However physiotherapist, psychologists, dieticians, and other disciplines along with six patients with AF were also represented. The expert panel (60% females) had a mean age of 50 years, and 65% were from Denmark. For the final referral model (figure 2), AF symptom burden and impaired health-related quality of life, anxiety and poor medicine compliance combined with a risk factor profile were the main inclusion criteria. Furthermore, it was important to know about the patients’ mental well-being, self-management abilities and comorbidities. Conclusion Consensus was reached for a generic referral model, which can be further adjusted in the appropriate clinical context. The model includes inclusion criteria which closely correlate with guidelines for AF management focusing on reducing the patients’ symptom and risk factor burden. The referral model is expected to increase the number of patients with AF referred to primary care health interventions, which could lead to better quality of life, fewer hospital admissions and lowered health care costs in AF.

Primary prevention of type 2 diabetes in the EU: A systematic review of interventional studies

Abstract Background The GBD 2019 study revealed that type 2 diabetes caused over 109.000 deaths and accounted for 5.3 million Disability Adjusted Life Years in the EU, with an estimated annual cost of EUR 300 billion in 2014. Interventions for primary prevention are pivotal in preventing diabetes, providing a structured approach to implementing lifestyle modifications or community-based programs. The objective of this study was to demonstrate the effectiveness of primary prevention interventions to prevent or delay the onset of type 2 diabetes in the EU member states. Methods A systematic review on six databases was conducted for relevant interventional studies carried out in the EU-28. The main outcome of the studies was determined by changes in the incidence of type 2 diabetes. Results The search yielded 18.885 records, of which 18 met the eligibility criteria. The following studies reported significant incidence reduction in the intervention groups: The Finnish Diabetes Prevention Study by individualised lifestyle intervention (HR: 0.614, 95%CI: 0.478-0.789), the Spanish CORDIOPREV Study through increased plant protein intake (HR: 0.64, 95%CI: 0.43-0.96), the Spanish PreDE trial by promoting healthy diet and physical exercise (RR: 0.68, 95%CI: 0.47-0.99), the Norfolk Diabetes Prevention Study with intensive diet-exercise counselling (OR: 0.57, 95%CI: 0.38-0.87), the Spanish PREDIMED and PREDIMED-Reus trials by mediterranean diet supplemented with extra virgin olive oil or mixed nuts (HR: 0.60, 95%CI: 0.43-0.85; HR: 0.49, 95%CI: 0.25-0.97; HR: 0.48, 95%CI: 0.24-0.96), and the Dutch SLIM Study with advices on diet and physical activity (RR: 0.53, 95%CI: 0.29-0.97). Conclusions Significantly decreasing the incidence of diabetes is feasible within primary healthcare settings through intensive lifestyle interventions targeting individuals at high risk. Therefore, it would be beneficial to incorporate these findings into the European guidelines for preventing type 2 diabetes. Key messages • Primary care plays an important role in the prevention of type 2 diabetes. • Well-defined primary lifestyle interventions are capable of slowing the progression from prediabetes to diabetes.

Developing an Evidence-Based Primary Cancer Prevention Repository: insights from the PIECES project

Abstract Introduction Up to 40% of cancer cases could be avoided through effective primary prevention. However, cancer prevention tends to be fragmented across Europe, leading to geographical health differences. The dissemination and scale-up of effective primary cancer prevention interventions may address this. Although effective cancer prevention programs exist, finding them and their materials (especially regarding implementation) can be challenging. Repositories of evidence-based interventions provide insight into “what is out there” and can support dissemination within and across national borders. The PIECES project aims to develop and disseminate a repository of evidence-based primary cancer prevention programs adaptable to European contexts, with information to aid adaptation and implementation across countries. Methods The development of the PIECES repository has been informed by established repositories such as NCI’s Evidence-Based Cancer Control Programs. The project team developed a scoring sheet with a selection of items that could be included in the repository. All participants rated each item on relevance and applicability and provided comments and suggestions. A final framework, including a set of minimal requirement items, was agreed upon during three online consensus building meetings. Results We created a repository of evidence-based primary cancer prevention interventions targeting modifiable risk factors suitable for implementation in European healthcare settings. This 22-item repository provides information about an intervention’s logic model, implementation practices, and appraisal of published evidence of effectiveness. Conclusions This repository is innovative as it includes practical information and tools to facilitate implementation. While initially built to serve the PIECES project, the repository is designed to be a valuable tool for European policymakers, researchers, and implementers. Lessons learned from this process will inform future developers. Key messages • A comprehensive cancer prevention intervention repository avoids “reinventing the wheel” and allows for more efficient use of existing interventions by building upon the best available evidence. • The ongoing efforts of the PIECES project represent a significant contribution to reduce cancer prevention disparities and to facilitate the adoption of evidence-based interventions in Europe.

Youth mental health and exposome

Abstract Mental health is a complex Public Health challenge, especially youth. A better understanding of factors that contribute to youth mental health and reduce the burden of youth mental health conditions such as executive and emotional functioning is needed to develop primary and secondary prevention interventions. One of the main challenges for better understanding mental health of youth is the complexity and diversity of exposures that individuals experience throughout their lifetime. There is a wide range of factors in the environment, and individuals are exposed to different combinations of external factors depending on their location, occupation, and lifestyles. These factors include physical (e.g., noise and indoor and outdoor air), chemical and social factors (e.g., neglect and abuse, relationship conflicts) based on the exposome framework. The exposome is a guiding framework for the multi-country study EARLY involving Albania, Belgium, Germany, Israel, Moldova, Portugal, Romania, Serbia, Spain, and Switzerland. EARLY is one of the first projects to theoretically explore and empirically investigate youth mental health in line with the exposome framework. We aim to identify factors influencing youth mental health with validated exposure measures. An exploratory list of measures was collected in Albania, Belgium, Germany, Israel, Moldova, Portugal, Romania, Serbia, Spain, and Switzerland. The measures vary widely. Besides the variation, there is still a lack of standardized methods for measuring environmental exposures. Limitations of measures affect reliability and validity. Therefore, an overview of available assessment methods and steps toward improving measures will be discussed in this talk.

A review on efficacy of polygenic risk score information on behavioral change and clinical outcomes

Abstract Background Polygenic Risk Score (PRS) represents a promising advancement in personalized medicine, enabling the inherited risk assessment for disease outcomes based on the effect of various common genetic variants. The utilization of PRS information to promote the adoption of healthier behaviors has witnessed an increase interest in recent years, but its full potential still needs to be fully addressed. Methods This systematic review aims to assess the efficacy of disclosing PRS information on individuals’ engagement in risk-reducing interventions. CENTRAL database has been searched up to December 2023 to identify randomized controlled trials (RCTs) comparing the disclosure of PRS results, with scenarios where other or no information is provided. We performed a preliminary meta-analysis on the mean difference of clinical and psychological outcomes between the two arms. Results Out of 4419 results, we included 12 studies. Trials focused on primary (83%), secondary (8%) and tertiary (8%) preventive interventions. As for the possible diseases predicted by the PRS, cardiovascular diseases (33%) were the most common (n = 4), along with cancers (33%), diabetes (25%) and metabolic disease (8%). PRS result disclosure was compared to standard care (n = 7), no information provided (n = 4), and family risk (n = 1). By pooling data from four comparable studies, we report a reduction in the mean difference for LDL cholesterol in the intervention group of -6.39mg/dL (95%CI -10.09, -2.70, I²=0%, p < 0.001). No significant changes were observed for systolic and diastolic blood pressure, and weight, in 3 studies and 4 analyzed studies, respectively. An increase in anxiety levels was observed towards the PRS group in 4 studies (SMD 0.24, 95%CI 0.02, 0.46, I² = 66%, p = 0.03). Conclusions Preliminary analysis show small or no effects of PRS disclosure on intermediate health or psychological outcomes. Larger trials assessing the potentiality of PRS disclosure are still needed. Key messages • From the analysis of twelve preventive trials on the efficacy of PRS on behavior change, we report a positive effect on LDL cholesterol reduction. • Larger well conducted trials are needed to integrate PRS-based information into future preventive strategies.

Association of type-D personality and left-ventricular remodelling in patients treated with primary percutaneous intervention after ST-segment elevation myocardial infarction

BackgroundType-D personality is an established predisposing factor for various diseases. Type-D traits have been shown to pose a 26% increased risk of coronary artery disease after controlling for other confounding factors. Significant associations have been reported between type-D personality traits and dyslipidaemia, impaired endothelial function, coronary heart disease (CAD), acute myocardial infarction, and other adverse cardiovascular events.ObjectiveTo assess the association between type-D personality and left-ventricular adverse remodelling in patients treated with percutaneous coronary intervention following index ST-segment elevation myocardial infarction.MethodsAll patients hospitalized and treated with percutaneous coronary intervention (PCI) after their index ST-segment elevation myocardial infarction (STEMI) between 1 January 2022 to 31 December 2023 were prospectively enrolled. Type-D personality traits in the study population were determined at baseline using type-D Scale-14 (DS14) instrument, whereas any positive change in left ventricular end diastolic volume (LVEDV) ≥ 20% at follow up period of 12-months from baseline was defined as left-ventricular adverse remodelling (LVAR). Univariate and multivariate analysis was done to establish the independent predictors of LVAR. The area under receiver-operating characteristic curve (AUROC) was employed to assess the sensitivity and specificity of the identified independent predictors.ResultsA total of 124 patients were enrolled in the study. The mean age of the study population was 67 ± 10 years and the overall incidence of LVAR was found to be 25%. Multivariate regression analysis revealed that type-D personality is a significant independent predictor of LVAR \\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\:(OR:2.51;95\\%CI:1.16-5.77;p=0.03)$$\\end{document} apart from the already established independent predictors Killip Class\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\:\\:(OR:7.30;95\\%CI:3.03-17.55;p<0.0001)$$\\end{document}, baseline Global Longitudinal strain (GLS)\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\:\\:(OR:2.69;95\\%CI:1.19-6.61;p=0.01)$$\\end{document}, and 3-vessel CAD\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\:\\:(OR:2.27;95CI:1.10-5.33;p=0.04)$$\\end{document}. In ROC curve analysis type-D personality as an independent predictor of LVAR achieved a sensitivity of 41.4% and a specificity of 87.1%, p < 0.02.ConclusionType-D personality trait is a significant independent predictor of LVAR in patients treated with PCI after their index-STEMI.

Effectiveness of a school- and primary care-based HPV vaccination intervention (the PrevHPV study)

Abstract Background HPV vaccine coverage (VC) remains lower than expected in many countries, particularly France. We developed and evaluated the PrevHPV multicomponent intervention to improve HPV VC among French adolescents. The components were ‘education and motivation’ of adolescents in schools, ‘at-school vaccination’, and ‘general practitioners’ (GPs) training’. We evaluated the effectiveness of the intervention two months after it ended. Methods We carried out a pragmatic cluster randomized controlled trial with incomplete factorial design in 14/25 French school districts (July 2021-April 2022). The cluster was the municipality (n = 91). The outcome was HPV VC (≥ 1 dose) two months after the intervention ended among 11-14-year-olds living in participating municipalities (data from the French national reimbursement database and from the trial). We performed two types of analyses: (1) without considering the dose of intervention received, using a linear model with one fixed effect per component, adjusted for baseline HPV VC; (2) a post hoc on-treatment analysis, rerunning the linear model by replacing the fixed effects with a quantitative ‘dose of intervention’ variable calculated for each component using data collected during the trial. Results For the three intervention components, estimates of the effect on VC at two months were greater for the on-treatment analyses than for the analysis that did not consider the intervention dose. For the ‘at-school vaccination’ component, the estimate increased from 5.50 percentage points (pp; p &amp;lt; 0.001) to 11.25 pp (p &amp;lt; 0.001). The ‘GPs’ training’ component reached significance (from -1.46 pp, p = 0.150 to 3.56 pp, p = 0.049). In both types of analyses, no significant effect was observed for ‘education and motivation’ (from -0.08 pp, p = 0.950 to 2.58 pp, p = 0.241). Conclusions Increasing HPV VC among adolescents requires the involvement of various stakeholders and could be achieved by combining interventions in both schools and primary care settings. Key messages • The PrevHPV study is supported by the French health authorities and conducted by a multidisciplinary consortium to tackle a long-lasting public health concern in France. • Offering free HPV vaccination at school significantly increased HPV VC; providing GPs with training and a dcision-aid tool helped increase HPV VC if the GPs completed the training.

8.N. Scientific session: Transferability and adaptation of vaccination interventions: Learning from underserved communities

Abstract Removing barriers in the health system that make it difficult for cultural, religious or ethnic minorities to access vaccinations is an urgent concern in order to prevent infectious diseases in the future. Childhood vaccine uptake for MMR and HPV in most underserved communities is lower than in the general population. The project RIVER-EU (Reducing Inequalities in Vaccine uptake in the European region - Engaging Underserved communities) engages the migrant community in Greece, females with a Turkish or Moroccan migration background in the Netherlands, the Ukrainian minority in Poland and marginalized Roma communities in Slovakia to remove health system barriers to vaccination. Barriers include, e.g., lack of culturally and linguistically appropriate information, financial barriers, insufficient capacities, coordination and delivery of health care. Based on a Participatory Action Research (PAR) approach we selected and adapted potentially transferable evidence-based interventions in partnership with the communities. First, we pre-selected 6 useful interventions from a realist review on 36 effective vaccine uptake interventions. Second, we assessed them in depth for their transferability. Building a bridge between evidence on interventions and community needs is not an easy task: We involved various stakeholders in a longitudinal process under consideration of contextual conditions in the primary intervention context and the context of the respective underserved community. We co-created knowledge through 25 workshops and 39 interviews or focus groups for decision-making and determining need for adaptation of selected interventions. The aim of this workshop is to present the results of this co-creative process in each country. Special attention is payed to facilitators and barriers for transferability of evidence-based interventions from the perspective of underserved communities, and contextual commonalities and differences that lead to a specific intervention tailoring. This workshop will contribute to an improved understanding of how to consider contextual needs underserved communities have to remove health system barriers to vaccination on the one hand and suitable evidence on interventions to improve their situation on the other hand. The workshop will include five presentations of eight minutes and a questions and answers session to involve the audience. First, an introductory presentation on transferability of interventions for HPV and MMR vaccine uptake to underserved communities in specific contexts will be given. Then each country will present the intervention(s) to address health system barriers adapted to their context. Thereby, we will underline common key elements that have potential for transferability in all countries. After all presentations, we will discuss the need for context-based decision-making on evidence-based interventions and intervention tailoring to improve vaccine uptake for cultural, religious or ethnic minorities. Key messages • Improving vaccine uptake in underserved communities requires local solutions with tailored interventions. Trusted partnerships with various stakeholders are key to reducing health system barriers. • Participatory approaches to evidence-informed decision-making build bridges between evidence on interventions and needs of underserved communities to understand the transferability of interventions.

Iterative Development of a Clinical Decision Support Tool to Enhance Naloxone Co-Prescribing.

Background Opioid overdoses have contributed significantly to mortality in the United States. Despite long-standing recommendations from the Centers for Disease Control and Prevention to co-prescribe naloxone for patients receiving opioids who are at high risk of overdose, compliance with these guidelines has remained low. Objectives The objective of this study was to develop and evaluate a hospital-wide electronic health record (EHR)-based clinical decision support (CDS) tool designed to promote naloxone co-prescription for high-risk opioids. Methods We employed an iterative approach to develop a point-of-order, interruptive EHR alert as the primary intervention and assessed naloxone prescription rates, EHR efficiency metrics, and barriers to adoption. Data was obtained from our EHR's clinical data warehouse and analyzed using statistical process control and Chi-square analyses to assess statistically significant differences in prescribing rates during the intervention periods. Results The initial implementation phase of the intervention, spanning from April 2019 to May 2022, yielded a nearly 3-fold increase in the proportion of high-risk patients receiving naloxone, rising from 13.4% [95% CI, 12.9% - 13.8%] to 36.4% [95% CI, 35.2% - 37.5%; p = 1 x 10-38]. Enhancements to the CDS design and logic during the subsequent iteration's study period, June 2022 and December 2023, reduced the number of CDS triggers by more than 30-fold while simultaneously driving an additional increase in naloxone receipt to 42.7% [95% CI, 40.6% - 44.8%; p = 2 x 10-5]. The efficiency of the CDS demonstrated marked improvement, with prescribers accepting the naloxone co-prescription recommendation provided by the CDS in 41.1% of the encounters in version two, compared to 6.2% in version one (p = 6 x 10-9). Conclusion This study offers a sustainable and scalable model to address low rates of naloxone co-prescription and may also be used to target other opportunities for improving guideline-concordant prescribing practices.

Immune system benefits of pulmonary rehabilitation in chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is a respiratory disease characterized by pulmonary and systemic inflammation. Inflammatory mediators show relationships with shortness of breath, exercise intolerance and health related quality of life. Pulmonary rehabilitation (PR), a comprehensive education and exercise training programme, is the most effective therapy for COPD and is associated with reduced exacerbation and hospitalization rates and increased survival. Exercise training, the primary physiological intervention within PR, is known to exert a beneficial anti-inflammatory effect in health and chronic diseases. The question of this review article is whether exercise training can also make such a beneficial anti-inflammatory effect in COPD. Experimental studies using smoke exposure mice models suggest that the response of the immune system to exercise training is favourably anti-inflammatory. However, the evidence about the response of most known inflammatory mediators (C-reactive protein, tumour necrosis factor α, interleukin 6, interleukin 10) to exercise training in COPD patients is inconsistent, making it difficult to conclude whether regular exercise training has an anti-inflammatory effect in COPD. It is also unclear whether COPD patients with more persistent inflammation are a subgroup that would benefit more from hypothesized immunomodulatory effects of exercise training (i.e., personalized treatment). Nevertheless, it seems that PR combined with maintenance exercise training (i.e., lifestyle change) might be more beneficial in controlling inflammation and slowing disease progress in COPD patients, specifically in those with early stages of disease.

Promoting Mental Health and Well-Being Among Adolescent Young Carers in Europe: A Cross-National Randomized Controlled Trial Study

Background/Objectives: This cross-national study focuses on adolescents who provide care and support to family members or significant others. Current evidence regarding their mental health and solutions to strengthen it is limited and mostly available in a few countries. The aim of this study is to evaluate the results of a primary prevention intervention for improving the mental health and well-being of adolescent young carers (AYCs) aged 15–17 years in six European countries. The intervention was based on a psychoeducational program and tools adapted from the Discoverer, Noticer, Advisor, and Values (DNA-V) model. Methods: We designed a randomized controlled trial with 217 AYCs participating in the study, either in the intervention or control group. Quantitative and qualitative data were collected via questionnaires at baseline, post-intervention, and a 3-month follow up. Results: The results were mixed, as positive improvements in primary (i.e., psychological well-being and skills) and secondary (school/training/work functioning) outcomes were shown by the experimental group but, in most cases, they were not statistically significant. The qualitative data supported positive claims about the intervention and its appropriateness for AYCs. Conclusions: The study implementation during the peak of the COVID-19 pandemic forced the consortium to adapt the design and may have influenced the results. More long-term studies are needed to assess similar mental health programs with this hard-to-reach target group.

What helps or hinders intervention success in primary care? Qualitative findings with older adults and primary care practitioners during a feasibility study to address malnutrition risk

BackgroundIn the UK, about 14% of community-dwelling adults aged 65 and over are estimated to be at risk of malnutrition. Screening older adults in primary care and treating those identified as ‘at risk’ may help reduce malnutrition risk and associated healthcare use, and improve quality of life. The aim of this study is to explore how primary care practitioners (PCPs) and older adults perceive, use and respond to an intervention to support those identified as ‘at risk’.MethodsWe developed and optimised an intervention (screen and treat protocol, online tools and printed materials) to support primary care practitioners to identify malnutrition risk among older adults, and intervene where necessary. We recruited older adults (described as ‘patients’ here) taking part in a feasibility study, and carried out semi-structured interviews to assess PCPs’ and patients’ engagement with the intervention, and identify any contextual issues that supported or undermined their engagement.ResultsFour themes were developed, encompassing patients’ and PCPs’ perceptions of undernutrition, study measures and appointments, constraints on PCPs’ enthusiasm to make a difference, and patients’ expectations of nutritional appointments. Key findings included patients commonly not accepting advice for undernutrition/malnutrition but welcoming support for their nutritional needs; checklists potentially distracting patients from recalling discussions about their nutritional needs; a tension between PCPs’ desire to recruit less-well patients and logistical difficulties in doing so; and patients compromising their nutritional needs to suit others.ConclusionsDiverse factors influence whether an intervention succeeds in primary care. PCPs learn about an intervention/study in different ways, vary in how they understand and accept its aims, and desire to make a difference to their patients. Patients bring perceptions and expectations about the study’s aims, coloured by their habits and preferences, prior experience of research and healthcare, and pressure from social expectations. Each aspect must be considered when developing a successful primary care intervention that is viewed as relevant and meaningful, and presented using language that aligns with participants’ values and goals. Our findings suggest that references to ‘malnutrition risk’ should be avoided in any patient-facing materials/interactions as participants do not accept or identify with this label.

Development and assessment of a machine learning tool for predicting emergency admission in Scotland

Emergency admissions (EA), where a patient requires urgent in-hospital care, are a major challenge for healthcare systems. The development of risk prediction models can partly alleviate this problem by supporting primary care interventions and public health planning. Here, we introduce SPARRAv4, a predictive score for EA risk that will be deployed nationwide in Scotland. SPARRAv4 was derived using supervised and unsupervised machine-learning methods applied to routinely collected electronic health records from approximately 4.8M Scottish residents (2013-18). We demonstrate improvements in discrimination and calibration with respect to previous scores deployed in Scotland, as well as stability over a 3-year timeframe. Our analysis also provides insights about the epidemiology of EA risk in Scotland, by studying predictive performance across different population sub-groups and reasons for admission, as well as by quantifying the effect of individual input features. Finally, we discuss broader challenges including reproducibility and how to safely update risk prediction models that are already deployed at population level.

Community Health Workers Linking Clinics and Schools and Asthma Control

Childhood asthma is characterized by pervasive disparities, including 3-fold higher hospitalization rates and 7-fold higher death rates for Black children compared with White children. To address asthma disparities, one must intervene in all lived environments. To determine if a community health worker (CHW) intervention to connect the primary care, home, and school for low-income minoritized school-aged children with asthma and their caregivers improves asthma control. This study was a hybrid effectiveness/implementation trial using a 2 × 2 factorial, cluster randomized clinical trial design of 36 schools crossed with participant-level randomization into a clinic-based CHW intervention. The study was conducted from May 2018 to June 2022. The intervention took place in primary care offices, homes, and 36 West Philadelphia, Pennsylvania, public and charter schools. Children aged 5 to 13 years with uncontrolled asthma were recruited from local primary care practices. Asthma management, trigger remediation, and care coordination occurred in school, home, and primary care settings. Children were followed up for 12 months. The Yes We Can Children's Asthma Program, Open Airways For Schools Plus, and school-based asthma therapy were implemented. Improvement in asthma control, as measured by the Asthma Control Questionnaire, comparing the mean difference between groups 1 year after randomization with their baseline (difference in differences). Both primary care and school interventions were dramatically disrupted by the COVID-19 pandemic; therefore, stratified analyses were performed to assess per-protocol intervention efficacy before the pandemic disruptions. A total of 1875 participants were approached, 1248 were excluded, and 1 was withdrawn. The 626 analyzed study participants (mean [SD] age, 8.7 [2.4] years; 363 male [58%]) self-identified as Black race (96%) and non-Hispanic ethnicity (98%). Although all groups had statistically significant improvements in asthma control from baseline to 12 months (P- group: -0.46; 95% CI, -0.58 to -0.33; P+ group: -0.57; 95% CI, -0.74 to -0.44; S- group: -0.47; 95% CI, -0.58 to -0.35; S+ group: -0.59; 95% CI, -0.74 to -0.44), none of the difference-in-differences estimates from the primary prespecified models showed a clinically meaningful improvement in asthma control. Analysis from the prepandemic interval, however, demonstrated that children in the combined clinic-school intervention had a statistically significant improvement in asthma control scores compared with control (-0.79; 95% CI, -1.40 to -0.18). This randomized clinical trial provides preliminary evidence that connecting all lived environments for care of children can be accomplished through linkages with CHWs.

A survey of dysphagia services practice in China.

Dysphagia services have only recently been formalised within Chinese health services. There has been no comprehensive evaluation of all aspects of dysphagia services practice in China. To provide a profile for the dysphagia practice in China by assessing various facets of dysphagia services. This is a survey study carried out from December 2022 to May 2023 online in China. One hundred fifty-nine respondents comprising doctors, nurses or therapists involved in the field of dysphagia rehabilitation completed a questionnaire via Sojump. The questionnaire included dichotomous (e.g., yes/no) and multiple-choice questions related to participants' general information and their provision of dysphagia management services. Results were analysed descriptively and the differences among different levels of hospitals were analysed. Approximately two-thirds of hospitals (67.9%) started dysphagia services within the last 5 years. A significant difference in the initiation of dysphagia rehabilitation was observed across different hospital levels (χ2=32.70;p<0.001). Routine dysphagia screening was a standard practice in most hospitals (71.7%), with the most frequently employed screening method being the water swallow test (95.6%). Clinical swallowing evaluation emerged as the preferred initial assessment method (80.5%) and the most utilised assessment method (91.8%). Video fluoroscopic swallow study and flexible endoscopic evaluation swallowing were used by 22.7% and 12.6% of respondents. A significant difference was observed in the choice of assessment methods across hospitals of different levels (χ2=43.397; p < 0.001). The majority of respondents (53.5%) primarily employed rehabilitation as the main intervention method (76%-100%). Most respondents indicated that they would reevaluate patients after treatment (74.8%) and reported routine follow-up with patients (60.4%). Despite the relatively recent development of dysphagia management in China, the practice patterns uncovered in this study are broadly consistent with Chinese guidelines and consensus. However, the use of instrumental assessments remains low, resulting in a lack of objective evaluation of patient conditions and outcomes. There is a need for policy and resource support in the field of dysphagia rehabilitation in China. What is already known on this subject Assessment and treatment methods for dysphagia are various across different patients, medical facilities and settings. There has been no comprehensive evaluation of all aspects of dysphagia rehabilitation practice in China. What this study adds to existing knowledge The study assessed various facets of dysphagia rehabilitation in China through an online survey. We found that the relatively recent development of dysphagia management in China, but the practice patterns uncovered in this study are broadly consistent with Chinese guidelines and consensus. Variations in practice patterns between hospitals of different levels may be attributed to resource constraints and patient needs. Besides, while rehabilitation exercises are the primary intervention method for dysphagia in China, the assessment largely centres on clinical swallowing evaluation. The use of instrumental assessments remains low, resulting in a lack of objective evaluation of patient conditions and outcomes. What are the clinical implications of this work? The study assessed various facets of dysphagia rehabilitation in China, and the results indicate that the use of instrumental assessments needs to be improved and there is a need for policy and resource support in the field of dysphagia rehabilitation in China.

An observational analysis of the impact of deltamethrin + piperonyl butoxide insecticide-treated nets on malaria case incidence and entomological indicators in Ebonyi State, Nigeria, 2017–2021

BackgroundIntense pyrethroid resistance threatens the effectiveness of the primary vector control intervention, insecticide-treated nets (ITNs), in Nigeria, the country with the largest malaria burden globally. In this study, the epidemiological and entomological impact of a new type of ITN (piperonyl-butoxide [PBO] ITNs) distributed in Ebonyi State were evaluated. The epidemiological impact was also compared to the impact of standard pyrethroid-only ITNs in Cross River State.MethodsA controlled interrupted time series analysis was conducted on monthly malaria incidence data collected at the health facility level, using a multilevel mixed-effects negative binomial model. Data were analysed two years before and after the PBO ITN campaign in Ebonyi State (December 2017 to November 2021). A pre-post analysis, with no comparison group, was used to assess the impact of PBO ITNs on human biting rates and indoor resting density in Ebonyi during the high transmission season immediately before and after the PBO ITN campaign.ResultsIn Ebonyi, PBO ITNs were associated with a 46.7% decrease (95%CI: -51.5, -40.8%; p < 0.001) in malaria case incidence in the 2 years after the PBO ITN distribution compared to a modelled scenario of no ITNs distributed, with a significant decrease from 269.6 predicted cases per 1000 population to 143.6. In Cross River, there was a significant 28.6% increase (95%CI: -10.4, 49.1%; p < 0.001) in malaria case incidence following the standard ITN distribution, with an increase from 71.2 predicted cases per 1000 population to 91.6. In Ebonyi, the human biting rate was 72% lower (IRR: 0.28; 95%CI 0.21, 0.39; p < 0.001) and indoor resting density was 73% lower (IRR: 0.27; 95%CI 0.21, 0.35; p < 0.001) after the PBO ITNs were distributed.ConclusionsThe epidemiological and entomological impact of the PBO ITNs underscore the impact of these ITNs in areas with confirmed pyrethroid resistance. These findings contribute to ongoing research on the impact of new types of ITNs in Nigeria, providing critical evidence for the Nigeria National Malaria Elimination Programme and other countries for future ITN procurement decisions as part of mass ITN campaign planning and malaria programming.

Ketogenic Approaches for the Treatment of Alzheimer's Disease.

Dementia represents one of the largest and most urgent public health problems across the globe. Modeling projections have estimated that delaying the onset of Alzheimer's disease (AD) by 6 months would reduce the prevalence by 5%, while a delay of 12 months would reduce the prevalence by 10%. One approach to achieving a delay in the onset of AD is to investigate lifestyle interventions that could be widely implemented with a favorable risk-benefit relationship and socioeconomic profile. Amongst such interventions, there is increasing evidence to support the use of ketogenic interventions in AD. Indeed, it is well known that cerebral glucose metabolism is impaired in AD, even at a preclinical stage, and a growing body of literature suggests that these findings may represent a primary pathogenic mechanism leading to neurodegeneration. Ketones are readily taken up by the brain and can serve as an alternative energy source for neurons and glia, hypothetically bypassing the glucose uptake deficit in AD. In this invited review we discuss the preclinical as well as clinical work aiming to increase ketones as a primary intervention in AD, including variations of the ketogenic diet, medium chain triglyceride supplementation, and newer, more experimental approaches.

Atherectomy Followed by Drug-Coated Balloon Angioplasty Versus Surgery for Symptomatic Deep Femoral Artery Arteriosclerotic Disease.

Limited data are available regarding endovascular therapy of arteriosclerotic lesions of the deep femoral artery (DFA). In this study, we compare the outcomes of atherectomy combined with drug-coated balloon (DCB) angioplasty and open repair of DFA lesions. This is a multicenter retrospective registry of patients with peripheral artery occlusive disease Rutherford categories 2 to 5 treated by surgical profundaplasty (SP) or atherectomy followed by DCB for DFA lesions (symptomatic DFA). The primary endpoint was clinically driven target lesion revascularization (CD-TLR). Overall mortality, target limb reinterventions, major amputation, and major adverse limb events (MALEs) were additionally analyzed. A total of 373 patients treated for an arteriosclerotic lesion of the DFA between February 2015 and August 2021 were included, 301 treated by SP and 72 with atherectomy and DCB. The rates of chronic limb threatening ischemia (CLTI) were 42.2% and 22.2% (p<0.002) for the surgical and endovascular groups, respectively. A previous DFA intervention was more frequent in the endovascular group (30.6% vs 15.3%; p<0.003). Patients who had an open repair were more likely to have an occlusion of the profunda (34.9% vs 19.7%, p=0.014), severe calcified lesions (26.5% vs 5.6%, p=0.001), and lesions longer than 20 mm (95.7% vs 88.7%, p=0.024). After propensity score matching, no significant differences were found with regard to technical and hemodynamic success. At 24 months, no difference was found in terms of freedom from CD-TLR (95.7% vs 96.8%), freedom from all-cause mortality (94.2% vs 98.5%), freedom from MALE (90.4% vs 93.9%), and amputation-free survival (93.8% vs 97%). Following endovascular therapy, length of stay was significantly lower (p<0.001) and any reintervention on the index limb was more frequent (p=0.039). Patients with CLTI, occlusion of profunda, severe calcified lesions, and longer lesions are more frequently treated by open surgery, while reinterventions are more commonly treated by atherectomy and DCB. In patients with comparable clinical and lesion characteristics after matching, endovascular and surgical reconstruction of DFA lesions showed similar mid-term clinical outcomes. However, the risk of reintervention at the index limb is higher after endovascular treatment. Randomized studies are now warranted to compare both techniques in terms of medical and financial aspects. Atherectomy followed by DCB of symptomatic DFA is safe and effective. In patients with comparable clinical and lesion characteristics, outcomes are comparable with surgery. However, the risk of reintervention at the index limb is higher after endovascular treatment. Therefore, whenever possible an additional outflow vessel revascularization should be performed by the time of the primary intervention. Randomized studies are warranted to compare endovascular techniques and open surgery also under economic aspects.

Managing COVID-19 outbreaks in prisons - a brief review of literature and key lessons learnt.

During the COVID-19 pandemic, prisons faced a unique challenge of preventing and managing outbreaks with minimal adverse impact. This study aims to describe the epidemiology of COVID-19 in prisons, identify lessons learnt and make recommendations. The authors used the PubMed advanced search function using MeSH terms; (coronavirus, sars) AND (prisons) AND (disease outbreaks). The authors included original research reporting COVID-19 outbreaks in prisons. All other types and non-English publications were excluded. The authors used a structured data abstraction template to extract data systematically, and a second author independently abstracted data from 10% of the papers for quality assurance. The search yielded 96 hits. The authors included 15 studies meeting the inclusion criteria. These studies were from four countries. Seven studies reported individual outbreaks. The mean and median number of inmates and staff were 1,765, 1,126 and 575, 510. The mean and median number of cases among inmates and staff were 584, 464, and 72, 77. The number of reported deaths varied from 0 to 11. The authors present the prison-specific hazards grouped under human factors, healthcare factors and environmental factors. The authors also summarise interventions deployed as either primary prevention interventions, such as vaccinations, or secondary prevention interventions, including screening and contact tracing. This narrative review summarises the prison-specific hazards, which include movement of people in and out of the person, moving in new prisoners from other prisons, mixing of prisoners when transporting to courts, limited medical and isolation resources, crowded dormitories, shared lavatories, small communal facilities, poor ventilation and overcrowding. The interventions included limiting non-medical transfers into and out of the persons, assigning staff members to specific areas, encouraging face coverings among prisoners and staff and social isolation measures within the constraints of the prison setting. The interventions were adopted by prison authorities to contain and manage the outbreaks. Public Health and prison authorities need to be aware of the risk of further outbreaks of COVID-19 and other infectious diseases in these settings and implement key measures identified in this review to minimise adverse outcomes.

Efficacy of Nonpharmacological Treatment in Children and Adolescent with Tic Disorder: A Systematic Review

Tic disorders (TDs) are neurodevelopmental conditions which affect 0.3–0.9% of individuals aged &lt; 18 years. Although tics often improve or resolve spontaneously over time, treatment is often recommended. Pharmacological approaches are widely used as primary interventions. However, their side effects encouraged the development and the interest in nonpharmacological approaches, whose efficacy in pediatric populations remains poorly understood. This systematic review aimed to evaluate the efficacy of nonpharmacological treatments for children and adolescents with TDs. A literature review was performed using PubMed, EBSCOhost, and JABA databases up to 16 May 2024. Eligible articles were randomized controlled trials, written in English and published in peer-reviewed journals, investigating the efficacy of nonpharmacological treatments in pediatric populations diagnosed with TDs. Significant evidence supported the efficacy of behavioral interventions such as the Comprehensive Behavioral Intervention for Tics (CBIT), its reduced version the Habit Reversal Therapy (HRT), and the Exposure and Relapse Prevention (ERP) in reducing tics and tic-related impairment among young people, as assessed through the Yale Global Tic Severity Scale. Behavioral interventions were generally effective in reducing tics, although some studies reported higher effects on motor tics when compared to vocal tics. High level of efficacy was observed for both face-to-face and online treatments. While future studies are needed to improve treatment effects, especially on vocal tics, as well as to have a better understanding of treatment components and modalities, taken together, the present findings support the use of nonpharmacological intervention for TDs in youth.
