The effectiveness of a coordinated preventive care approach for healthy ageing (UHCE) among older persons in five European cities: A pre-post controlled trial

Background: Older persons often have multiple health and social problems and need a variety of health services. A coordinated preventive approach that integrates the provision of health and social care services could promote healthy ageing. Such an approach can be organised differently, depending on the availability and organizational structures in the local context. Therefore, it is important to evaluate the effectiveness of a coordinated preventive care approach in various European settings. Objectives: This study explored the effects of a coordinated preventive health and social care approach on the lifestyle, health and quality of life of community-dwelling older persons in five European cities. Design: International multi-center pre-post controlled trial. Setting: Community settings in cities in the United Kingdom, Greece, Croatia, the Netherlands and Spain. Participants: 1844 community-dwelling older persons (mean age = 79.5; SD = 5.6). Methods: The Urban Health Centres Europe (UHCE) approach consisted of a preventive multidimensional health assessment and, if a person was at-risk, coordinated care-pathways targeted at fall risk, appropriate medication use, loneliness and frailty. Intervention and control sites were chosen based on their location in distinct neighbourhoods in the participating cities. Persons in the catchment area of the intervention sites ‘the intervention group’ received the UHCE a

Evaluation design of Urban Health Centres Europe (UHCE): Preventive integrated health and social care for community-dwelling older persons in five European cities

Background: Older persons often have interacting physical and social problems and complex care needs. An integrated care approach in the local context with collaborations between community-, social-, and health-focused organisations can contribute to the promotion of independent living and quality of life. In the Urban Health Centres Europe (UHCE) project, five European cities (Greater Manchester, United Kingdom; Pallini (in Greater Athens Area), Greece; Rijeka, Croatia; Rotterdam, the Netherlands; and Valencia, Spain) develop and implement a care template that integrates health and social care and includes a preventive approach. The UHCE project includes an effect and process evaluation. Methods: In a one-year pre-post controlled trial, in each city 250 participants aged 75+ years are recruited to receive the UHCE approach and are compared with 250 participants who receive 'care as usual'. Benefits of UHCE approach in terms of healthy life styles, fall risk, appropriate medication use, loneliness level and frailty, and in terms of level of independence and health-related quality of life and health care use are assessed. A multilevel modeling approach is used for the analyses. The process evaluation is used to provide insight into the reach of the target population, the extent to which elements of the UHCE approach are executed as planned and the satisfaction of the participants. Discussion: The UHCE project will provide new insight into the feasibility and effectiveness of an integrated care approach for older persons in different European settings.

Quorum sensing network in clinical strains of A. baumannii : AidA is a new quorum quenching enzyme

Acinetobacter baumannii is an important pathogen that causes nosocomial infections generally associated with high mortality and morbidity in Intensive Care Units (ICUs). Currently, little is known about the Quorum Sensing (QS)/Quorum Quenching (QQ) systems of this pathogen. We analyzed these mechanisms in seven clinical isolates of A. baumannii. Microarray analysis of one of these clinical isolates, Ab1 (A. baumannii ST-2-clon-2010), previously cultured in the presence of 3-oxo-C12-HSL (a QS signalling molecule) revealed a putative QQ enzyme (α/β hydrolase gene, AidA). This QQ enzyme was present in all nonmotile clinical isolates (67% of which were isolated from the respiratory tract) cultured in nutrient depleted LB medium. Interestingly, this gene was not located in the genome of the only motile clinical strain growing in this medium (A. baumannii strain Ab421-GEIH-2010 [Ab7], isolated from a blood sample). The AidA protein expressed in E. coli showed QQ activity. Finally, we observed downregulation of the AidA protein (QQ system attenuation) in the presence of HO (ROS stress). In conclusion, most of the A. baumannii clinical strains were not surface motile (84%) and were of respiratory origin (67%). Only the pilT gene was involved in surface motility and related to the QS system. Finally, a new QQ enzyme (α/β hydrolase gene, AidA protein) was detected in these strains
