Systematic review of surveillance systems for AMR in Africa.

AIMS: Surveillance is a useful tool for tracking antimicrobial resistance (AMR) trends, patterns, therapeutic and policy interventions. Proper correlation of surveillance data gives meaningful insight into the underlying epidemiology and facilitates development of rational interventions. This comprehensive review aims to identify, classify and assess gaps in Global Antimicrobial Resistance and Use Surveillance System (GLASS) reporting and national action plan (NAP) implementation in Africa. METHODS: Articles published in English were searched across five electronic databases (PubMed, Scopus, Embase, AJOL and Cochrane) and grey literature. Articles were screened against inclusion/exclusion criteria and data from eligible studies were retrieved and analysed. This systematic review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) on 31 July 2020 under protocol CRD42020192165. RESULTS: Of the 4304 records found, only 32 met the initial inclusion criteria (4 peer reviews and 28 were grey literature). From these records, 41 surveillance systems were identified (30 national and 11 transnational). After final review of reported outcomes, only 23 national surveillance systems met the inclusion criteria. Indicators recorded from these systems shows lack of external quality assessment (EQA) in some systems and limited reporting of parameters such as infection origin, patient population and pathogen types. CONCLUSIONS: The outcome of the review shows that although AMR surveillance has been implemented in 23 out of the 47 countries in the region, a number of limitations exist in the surveillance methods and reporting protocols that can impair the usefulness, validity and trustworthiness of data generated from these surveillance systems.

The Content of Nostalgic Memories Among People Living with Dementia.

Although dementia may affect the reliability of autobiographical memories, the psychological properties of nostalgic memories may be preserved. We compared the content of nostalgic (n = 36) and ordinary (n = 31) narratives of 67 participants living with dementia. Narratives were rated according to their self-oriented, social, and existential properties, as well as their affective content. Social properties and affective content were assessed using a linguistic word count procedure. Compared to the ordinary narratives described in the control condition, nostalgic narratives described a typical events, expressed more positive affect, and had more expressions of self-esteem and self-continuity. They were also rated higher on companionship, connectedness and the closeness of relationships, and reflected life as being meaningful. Despite their cognitive impairment, people living with dementia experience nostalgia in similar ways to cognitively healthy adults, with their nostalgic narratives containing self-oriented, social, and existential properties.

Effectiveness of Infection Prevention and Control Interventions in Healthcare Facilities in Africa: A Systematic Review.

BACKGROUND: Healthcare associated infections (HAIs) are a major threat to patient safety and quality care. However, they are avoidable by implementing evidence-based infection prevention and control measures. This review evaluated the evidence of the effectiveness of Infection Prevention and Control (IPC) interventions in reducing rates of HAIs in healthcare settings in Africa. METHOD: We searched several databases: CENTRAL, EMBASE, PUBMED, CINAHL, WHO IRIS and AJOL for primary studies reporting rates of the four most frequent HAIs: surgical site infections, central line-associated blood stream infections, catheter-associated urinary tract infections, ventilator-associated pneumoniae and increase in hand hygiene compliance. Two reviewers appraised the studies and PRISMA guidelines were followed. RESULTS: Out of 4,624 studies identified from databases and additional sources, 15 studies were finally included in the review. Majority of studies were of pre and post-test study design. All the studies implemented a combination of interventions and not as stand-alone components. Across all included studies, an improvement was reported in at least one primary outcome. CONCLUSION: Our review highlights the potential of IPC interventions in reducing HAIs and improving compliance with hand hygiene in healthcare facilities in Africa. However, the certainty of evidence was low for majority of the outcomes. For future research, we recommend more pragmatic study designs with improved methodological rigor.

Socioeconomic Determinants of Cardiovascular Diseases, Obesity, and Diabetes among Migrants in the United Kingdom: A Systematic Review.

There has been little agreement on the role that socioeconomic factors play in the aetiology of cardiovascular diseases (CVDs), obesity, and diabetes among migrants in the United Kingdom (UK). We systematically reviewed the existing evidence on this association to contribute to filling this gap in the literature. Two reviewers were involved at each stage of the review process to ensure validity. We comprehensively searched through several electronic databases and grey literature sources to identify potentially eligible papers for our review. We extracted data from our finally included studies and appraised the methodological rigour of our studies. A narrative synthesis approach was used to synthesise and interpret the extracted data. We sieved through 2485 records identified from our search and finally obtained 10 studies that met our inclusion criteria. The findings of this review show that there is a trend towards an association between socioeconomic factors and CVDs, diabetes, and obesity among migrants in the UK. However, the picture was more complex when specific socioeconomic variables and migrant subgroups were analysed. The evidence for this association is inconclusive and its causal relationship remains speculative. There is, therefore, the need for further research to understand the exact association between socioeconomic factors and CVD, diabetes, and obesity among migrants in the UK.

Nostalgic conversations: The co-production of an intervention package for people living with dementia and their spouse.

OBJECTIVES: Nostalgic memories are more social than other forms of autobiographical recall, often refer to atypical events, express more positive affect and reflect life as meaningful. Recalling a nostalgic (compared to ordinary) memory increases self-esteem, self-growth, meaning in life and social connectedness for people living with dementia. We set two objectives: to work with people living with dementia to develop an intervention based on nostalgia, and to assess whether couples could engage in nostalgic conversations. METHOD: Our research fell into three phases. Initially, we consulted with people living with dementia and with carers to identify the parameters for a nostalgic intervention. From this, we drafted a workbook that contained triggers for nostalgic conversations, which we then took back to the public contributors for refinement. Finally, we trialled the workbook over 5 weeks with six couples, each of which included a person living with dementia. We assessed pre- and post-intervention self-esteem, self-growth, meaning in life and social connectedness for participants with dementia and social connectedness for carers. We then calculated Reliable Change Index scores and established levels of clinically significant change. We also interviewed couples at the end of the intervention to explore its implementation and acceptability. RESULTS: All six couples could identify nostalgic memories, with five couples successfully integrating the nostalgic conversations into their day-to-day lives. A sixth couple found it difficult to engage fully with the intervention, but still considered it useful. All six couples manifested a reliable change in at least one outcome, with one couple showing reliable change across three outcomes. CONCLUSION: The psychological benefits of nostalgia have been robustly demonstrated in laboratory-based studies. This co-production of an intervention that sets nostalgic recall into the context of a conversation has clinical potential but requires further investigation through a larger study.

Psychological and Mnemonic Benefits of Nostalgia for People with Dementia.

BACKGROUND: Studies with non-clinical populations show that nostalgia increases psychological resources, such as self-esteem and social connectedness. OBJECTIVES: Our objectives were to find out if the benefits of nostalgia in non-clinical populations generalize to people with dementia and if nostalgia facilitates recall of dementia-related information. METHODS: All three experiments recruited participants with mild or moderate levels of dementia. Experiment 1 tested whether nostalgia (compared to control) enhances psychological resources among 27 participants. Experiment 2 used music to induce nostalgia (compared to control) in 29 participants. Experiment 3 compared recall for self-referent dementia statements among 50 participants randomized to either a nostalgia or control condition. Findings across experiments were synthesized with integrative data analysis. RESULTS: Nostalgia (compared to control) significantly increased self-reported social connectedness, meaning in life, self-continuity, optimism, self-esteem, and positive (but not negative) affect (Experiments 1-3). Compared to controls, nostalgic participants also recalled significantly more self-referent dementia-related information (Experiment 3). CONCLUSION: This series of experiments extends social psychological research with non-clinical populations into dementia care, providing evidence that nostalgia significantly enhances psychological resources. The finding that nostalgia increased recall of self-referent statements about dementia suggests that this emotion lends participants the fortitude to face the threat posed by their illness. The finding has potentially important clinical implications both for the development of reminiscence therapy and for facilitating adjustment to a diagnosis of dementia.

Primary care-led dementia diagnosis services in South Gloucestershire: Themes from people and families living with dementia and health care professionals.

BACKGROUND: Primary care-led dementia services are an increasingly common form of service delivery; however, little is known about how these services are understood by their main stakeholders: the patients, family members and health care professionals. A primary care-led dementia service was piloted in the South Gloucestershire area during 2012, in which general practitioners (GPs) led the process of assessment and establishing a diagnosis. Of the 26 surgeries in the area, 11 initially agreed to participate in the pilot, with 12 more joining the project by the end of December 2012. AIM: The aim of this study was to provide a qualitative analysis of the experiences of health care professionals, patients and their families, of the new process of assessment, diagnosis and treatment of dementia within a primary care service. METHODS: Four patients, three care-givers and eight health care professionals were interviewed by peer researchers - all of whom were current care-givers. Interviews were transcribed and analysed using thematic analysis following Braun and Clarke's model. Data were also gathered about the number of referrals and what happened to these referrals. RESULTS: Themes gathered into four main areas: 'the journey', 'what next?', 'the benefits and limits of primary care' and 'are GPs getting it right'? CONCLUSIONS: The analysis provided a perspective on the experiences of patients, family members and health care professionals involved in the relocation of part of the memory service, from secondary care (memory clinics) to primary care, being piloted in South Gloucestershire. This identified both practical issues to be improved upon as well as possible barriers.
