Finding the attractor of anger: Bridging the gap between dynamic concepts and empirical data

Although it accounts for the prototypical course of emotions, the attractor concept has hardly ever been used empirically. Authors applied Empirical Differential Equations (EDE) to frequent (hourly) anger ratings to find the attractor of anger. The attractor concept, its neurological basis, and EDE are explained. The attractor of anger follows an underdamped oscillator, and is affected by the capacity to inhibit prepotent responses. Anger accelerates less fast when inhibitory control increases. Results stress the internal dynamics of emotions, and help to bridge the gap between concepts from dynamic systems theory and empirical dat

Leadership development programmes in healthcare research: a systematic review, meta-analysis and meta-aggregation

Background: Academic institutions benefit from researchers adopting leadership positions and, subsequently, leadership development programmes are of increasing importance. Despite this, no evaluation of the evidence basis for leadership development programmes for healthcare researchers has been conducted. In this study, the authors reviewed leadership development programmes for healthcare researchers and aimed to identify their impact and the factors which influenced this impact. Methods: The authors searched MEDLINE, EMBASE, CINAHL and PsycINFO between January 2000 and January 2023 for evaluations of leadership development programmes with healthcare researchers. The authors synthesised results through exploratory meta-analysis and meta-aggregation and used the Medical Education Research Study Quality Instrument (MERSQI) and Joanna Briggs Institute (JBI) Checklist for Qualitative Studies to identify higher-reliability studies. Results: 48 studies met inclusion criteria, of which approximately half (22) met the criteria for higher reliability. The median critical appraisal score was 10.5/18 for the MERSQI and 3.5/10 for the JBI. Common causes of low study quality appraisal related to study design, data analysis and reporting. Evaluations principally consisted of questionnaires measuring self-assessed outcomes. Interventions were primarily focused on junior academics. Overall, 163/168 categorised programme outcomes were positive. Coaching, experiential learning/project work and mentoring were associated with increased organisational outcomes. Conclusion: Educational methods appeared to be more important for organisational outcomes than specific educational content. To facilitate organisational outcomes, educational methods should include coaching, project work and mentoring. Programmes delivered by external faculty were less likely to be associated with organisational outcomes than those with internal or mixed faculty, but this needs further investigation. Finally, improving evaluation design will allow educators and evaluators to more effectively understand factors which are reliably associated with organisational outcomes of leadership development

Hormone replacement therapy, mammography screening and changing age-specific incidence rates of breast cancer: an ecological study comparing two European populations

Background: In 2003, for the first time, US breast cancer incidence rates have fallen. Experts argue whether this is due to the reduced uptake of screening mammography or to lower use of Hormone Replacement Therapy (HRT). This study aims to disentangle the respective impact of screening and HRT on age-incidence rates and histology of breast cancer, by comparing two populations with comparably high levels of screening mammography, but with different prevalence of HRT. Methods: We included all invasive breast cancers recorded at the Geneva cancer registry (n=4,909) and the Netherlands Cancer Registry (n=152,428) between 1989-2003. We compared age-specific incidence rates and trends in histological subtyping between the two populations. Results: Between 1989-1991, incidence rates increased with age in both populations. In 2001-2003, women aged 60-64years showed highest incidence rates in Geneva, while in the Netherlands incidence rates continued to increase with age. The annual increase in ductal cancer incidence was similar in the Netherlands (2.3%) and Geneva (2.5%), but the annual increase in lobular cancer was sharper in Geneva (10%) than in the Netherlands (5%). Conclusion: The sharp differences in age distribution and histological subtyping of breast cancer between two European populations are not attributable to screening, since both populations have a high uptake of mammography screening. Since the prevalence of HRT use is very high in Geneva and rather low in the Netherlands, HRT may explain these discrepancies. However, other etiological factors and differences in histological assessment may also have played a rol

The implementation of community-based programs in Vietnam is promising in promoting health

Background: Low-and middle-income countries mostly have ageing populations with many unmet economic, social, or health-related needs, Vietnam being an example. Community-based support in Vietnam, organized as Intergenerational Self-Help Clubs (ISHCs) based on the Older People Associations (OPA) model, can help to meet these needs by the provision of services for various aspects of life. This study aims to assess the implementation of the ISHCs and whether successful implementation is associated with more member-reported positive health.Methods: We used the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework to evaluate the implementation using multiple data sources: ISHC board surveys (n = 97), ISHC member surveys (n = 5,080 in 2019 and n = 5,555 in 2020), focus group discussions (6; n = 44), and interviews with members and board leaders (n = 4).Results: Reach ranged between 46 and 83% of ISHCs reaching target groups, with a majority of women and older people participating. Regarding Effectiveness, members indicated high satisfaction with the ISHCs. Adoption scores were high, with 74%–99% for healthcare and community support activities, and in 2019, higher adoption scores were associated with more members reporting good positive health. In 2020, reported positive health slightly decreased, probably due to the influence of the COVID-19 pandemic. A total of 61 ISHCs had consistent or improving Implementation from 2019 to 2020, and confidence in Maintenance was high.Conclusion: The implementation of the OPA model in Vietnam is promising regarding its promotion of health and may help to tackle the needs of an ageing population. This study further shows that the RE-AIM framework helps to assess community health promotion approaches.</p
