Early in the COVID-19 pandemic, screening was initiated in several settings to mitigate asymptomatic transmission of SARS-CoV-2. However, this practice was later discouraged by the Society for Healthcare Epidemiology of America. This single-center retrospective study demonstrates limited utility of SARS-CoV-2 screening tests in asymptomatic HCT and CAR T-cell patients.

Health visiting in England is a universal service that aims to promote the healthy development of children aged under five years and safeguard their welfare. We consulted stakeholders about their priorities for research into health visiting and also used these consultations and a literature review to generate a logic model. Parents wanted research to explore how health visiting teams can provide a caring, responsive, accessible service (the mechanisms of change). Policymakers, commissioners, and clinical service leads wanted descriptions and evaluations of currently implemented and ‘gold standard’ health visiting. The challenges to evaluating health visiting (data quality, defining the intervention, measuring appropriate outcomes, and estimating causal effects) mean that quasi-experimental studies that rely on administrative data will likely underestimate impact or even fail to detect impact where it exists. Prospective and experimental studies are needed to understand how health visiting influences infant–parent attachments, breastfeeding, childhood accidents, family nutrition, school readiness, and mental health and well-being.

We surveyed healthcare professionals at a cancer center regarding their knowledge and perceptions of antibiotic use. Most knew the term “antimicrobial stewardship.” Nurses and other staff were less likely than pharmacists or providers to answer knowledge-based questions correctly. Opportunities exist to improve antibiotic knowledge among cancer center staff.

As the ageing population in China continues to grow, more people will be living with long-term health conditions and require support from family care-givers. This scoping review therefore aims to explore sources of stress and coping mechanisms adopted by care-givers of older relatives living with long-term conditions in mainland China. Literature searches were conducted in English (CINAHL, EMBASE, MEDLINE, PsycINFO and SCOPUS) and Chinese (CNKI, WANFANG DATA, CQVIP and CBM) databases between October and November 2019. The searches focused on the stressors and coping mechanisms utilised by family care-givers residing in the community. Narrative synthesis was used to identify themes within the data. Forty-six papers were included: 20 papers from English and 26 from Chinese databases. Six themes captured stressors: care-giving time (N = 22), financial resources (N = 17), role and personal strains (N = 42), preparedness (N = 4), social roles (N = 10) and lack of adequate formal support (N = 22); and one theme captured coping (N = 14). Unmet needs of care-givers of older relatives in mainland China were found to be extensive. Only a few studies had attempted to explore the causal link between stressors, coping and the influence of culture. Findings underscore the significance of adequately capturing intricacies around care-givers’ unmet needs, rather than generalising on the basis of culture. Qualitative studies are critical to providing a better understanding of the relationship between stressors, coping and resources afforded to care-givers by their cultural environment. Having such understanding is crucial to inform the development of competent care, which promotes self-efficacy and self-actualisation in care-givers in mainland China.

Despite the numerous challenges of ageing in a foreign land, many older immigrants are fairly resilient and report experiencing good wellbeing. The key question that the present paper addresses is how this is achieved. Drawing on frameworks from cross-cultural and social identity literatures, the present study proposes and tests a model of serial multiple mediation that identifies possible mechanisms supporting the wellbeing of older immigrants who have resided in the host country for some time. In this model, it is predicted that new group memberships acquired post-migration enable access to social support that in turn provides the basis for perceived integration, which enhances wellbeing. This model was tested in a survey study with 102 older people, whose mean age was 80.3 years and who had migrated to Australia from Asian, European, and Central and South American countries on average 36 years previously. The survey assessed cultural identity, social group memberships acquired post-migration, perceived social support, perceived integration and wellbeing. Results supported the hypothesised model, indicating that joining new heritage culture and wider groups in Australia post-migration provided a platform for social support and integration, which enhanced life satisfaction and reduced loneliness. The implications of these findings for theory and adapting successfully to both migration and ageing are discussed.

OBJECTIVES/GOALS: To explore the patterns, sequence, quantity, frequency and duration of poly substance use among adults for back translation of information to rodent models. METHODS/STUDY POPULATION: From May –December 2019, we conducted 13 focus group discussions with adults 19 to 63 years of age who reported concurrent use of cocaine with alcohol and/or marijuana in the past 30 days. All participants were recruited from the community through community outreach activities. Written informed consent was obtained and all focus group discussions were audio recorded, transcribed and analyzed using the qualitative data analysis software Atlas Ti™. RESULTS/ANTICIPATED RESULTS: A total of 34 cocaine users, (68% male, and 59% minority) participated. The majority reported cocaine as the drug of preference, while marijuana and alcohol were used to extend or control the ‘highs’, or ‘to take the edge off’ after cocaine use. All participants reported when they used alcohol with cocaine, they could keep drinking a large amount of alcohol without feeling its effect. Participants also reported using marijuana throughout the day while driving, at work, or in class. Frequent patterns noted for the study included using two drugs at the same time or right before or after each other with alcohol used throughout the day. Participants also gave feedback on our Poly Substance Use (PSU) assessment that captures exact patterns so that the most common can be translated for the rodent models. DISCUSSION/SIGNIFICANCE OF IMPACT: Our focus group discussions provided detailed information on patterns, sequence, quantity, and types of poly substance use that could be useful for developing a poly substance use assessment in the collection of data for rodent models to understand effects of poly substance use.
