A qualitative study of informal caregiver perceptions of the benefits of an early dementia diagnosis.

BACKGROUND: Current and former dementia policies in the United Kingdom (UK) recommend diagnosing dementia early, or as close to the onset of symptoms as possible. Informal caregivers play an important role in initiating the diagnostic process and providing support to people living with dementia. Therefore, this study aimed to explore caregiver perceptions of the benefits of an early diagnosis. METHODS: We conducted semi-structured interviews with 12 current and former informal caregivers to people with dementia in the UK in 2020. We analysed the interviews using thematic analysis. RESULTS: Benefits of an early diagnosis included: (1) protecting the person with dementia from financial or physical harm, (2) timely decision-making, and (3) access to services and treatments following a diagnosis. We identified three conditions necessary for the benefits of an early diagnosis to be felt: (1) adequate prognostic information, (2) someone to advocate on behalf of the person with dementia, and (3) a willingness to seek and accept the diagnosis. CONCLUSIONS: In this study, we identified how diagnosing dementia close to the onset of symptoms could be beneficial and the conditions necessary for these benefits to be felt. The findings highlight the importance of an early diagnosis for enabling people with dementia and caregivers to make practical arrangements and to access services. Further research is needed to build on the findings of this study by exploring the perspectives of people with dementia and by including a larger, more diverse sample of caregivers.

Differences in survival and mortality in minority ethnic groups with dementia: A systematic review and meta-analysis.

OBJECTIVES: Although there are disparities in both risk of developing dementia and accessibility of dementia services for certain minority ethnic groups in the United States and United Kingdom, disparities in survival after a dementia diagnosis are less well-studied. Our objective was to systematically review the literature to investigate racial/ethnic differences in survival and mortality in dementia. METHODS: We searched Embase, Ovid MEDLINE, Global Health and PsycINFO from inception to November 2018 for studies comparing survival or mortality over time in at least two race/ethnicity groups. Studies from any country were included but analysed separately. We used narrative synthesis and random-effects meta-analysis to synthesise findings. The Newcastle-Ottawa Scale was used to assess quality and risk of bias in individual studies. RESULTS: We identified 22 articles, most from the United States (n = 17), as well as the United Kingdom (n = 3) and the Netherlands (n = 1). In a meta-analysis of US studies, hazard of mortality was lower in Black/African American groups (Pooled Hazard Ratio = 0.86, 95% CI = 0.82-0.91, I2  = 17%, from four studies) and Hispanic/Latino groups (Pooled HR = 0.65, 95% CI = 0.50-0.84, I2  = 86%, from four studies) versus comparison groups. However, study quality was mixed, and in particular, quality of reporting of race/ethnicity was inconsistent. CONCLUSION: Literature indicates that Black/African American and Hispanic/Latino groups may experience lower mortality in dementia versus comparison groups in the United States, but further research, using clearer and more and consistent reporting of race/ethnicity, is necessary to understand what drives these patterns and their implications for policy and practice.

A systematic review of the latent structure of the Center for Epidemiologic Studies Depression Scale (CES-D) amongst adolescents.

BACKGROUND: The Centre for Epidemiologic Studies Depression Scale (CES-D) is a commonly used psychometric scale of depression. A four-factor structure (depressed affect, positive affect, somatic symptoms, and interpersonal difficulties) was initially identified in an American sample aged 18 to 65. Despite emerging evidence, a latent structure has not been established in adolescents. This review aimed to investigate the factor structure of the CES-D in adolescents. METHODS: We searched Web of Science, PsychINFO and Scopus and included peer-reviewed, original studies assessing the factor structure of the 20-item CES-D in adolescents aged ≤18. Two independent researchers screened results and extracted data. RESULTS: Thirteen studies met the inclusion criteria and were primarily from school-based samples in the USA or Asia. Studies that conducted confirmatory factor analysis (CFA; n = 9) reported a four-factor structure consistent with the original factor structure; these studies were primarily USA-based. Conversely, studies that conducted exploratory factor analysis (EFA) reported distinct two or three factor structures (n = 4) and were primarily based in Asia. LIMITATIONS: Studies in a non-English language and those that included individuals aged > 18 years were excluded. Ethnic or cultural differences as well as different analytical methods impacted generalisability of results. The use of CFA as the primary analysis may have biased towards a four-factor structure. CONCLUSIONS: A four-factor CES-D structure was an appropriate fit for adolescents in Western countries; further research is required to determine the fit in in Asian countries. This has important implications for clinical use of the scale. Future research should consider how cultural differences shape the experience of depression in adolescents.

Filipino help-seeking for mental health problems and associated barriers and facilitators: a systematic review.

PURPOSE: This systematic review aims to synthesise the evidence on behavioural and attitudinal patterns as well as barriers and enablers in Filipino formal help-seeking. METHODS: Using PRISMA framework, 15 studies conducted in 7 countries on Filipino help-seeking were appraised through narrative synthesis. RESULTS: Filipinos across the world have general reluctance and unfavourable attitude towards formal help-seeking despite high rates of psychological distress. They prefer seeking help from close family and friends. Barriers cited by Filipinos living in the Philippines include financial constraints and inaccessibility of services, whereas overseas Filipinos were hampered by immigration status, lack of health insurance, language difficulty, experience of discrimination and lack of acculturation to host culture. Both groups were hindered by self and social stigma attached to mental disorder, and by concern for loss of face, sense of shame, and adherence to Asian values of conformity to norms where mental illness is considered unacceptable. Filipinos are also prevented from seeking help by their sense of resilience and self-reliance, but this is explored only in qualitative studies. They utilize special mental health care only as the last resort or when problems become severe. Other prominent facilitators include perception of distress, influence of social support, financial capacity and previous positive experience in formal help. CONCLUSION: We confirmed the low utilization of mental health services among Filipinos regardless of their locations, with mental health stigma as primary barrier, while resilience and self-reliance as coping strategies were cited in qualitative studies. Social support and problem severity were cited as prominent facilitators.

Latent structure of the Centre for Epidemiologic Studies Depression Scale (CES-D) in older adult populations: a systematic review.

Objective: The Center for Epidemiologic Studies Depression Scale (CES-D) is a 20-item, self-report metric intended to measure depression. Despite being one of the most popular depression scales, the psychometric properties, specifically the underlying factor structure of the scale, have come under scrutiny. The latent structure of a scale is a key indicator of its construct validity, i.e. the degree to which the intended variable is captured. To date, a comprehensive review of the latent structure of the CES-D in older adult populations (≥65 years old) has not been conducted. We aimed to examine the latent structure of the CES-D in samples of older adults to assess its ability to capture depressive symptoms.Methods: A systematic review across Scopus, Web of Science, and PsycINFO databases was conducted. Original studies conducting latent variable analysis of the 20-item CES-D in samples aged ≥65 years old were included.Results: Included studies (n = 6) were primarily conducted with community-dwelling older adults in the United States. Studies that conducted exploratory and confirmatory factor analysis (n = 2) revealed two latent factors, whereas those conducting confirmatory factor analysis of previously identified structures (n = 4) revealed four-factor structures in line with the original four-factor structure.Conclusions: A general alignment with the original four-factor structure of the CES-D provides tentative support for continued use amongst older adults; however, further research is required to provide conclusive evidence for these psychometric properties.

Ethnicity and survival after a dementia diagnosis: a retrospective cohort study using electronic health record data.

BACKGROUND: Individuals from minority ethnic groups in the UK are thought to be at higher risk of developing dementia while facing additional barriers to receiving timely care. However, few studies in the UK have examined if there are ethnic disparities in survival once individuals receive a dementia diagnosis. METHODS: We conducted a retrospective cohort study using electronic health record data of individuals diagnosed with dementia from a large secondary mental healthcare provider in London. Patients from Black African, Black Caribbean, South Asian, White British, and White Irish ethnic backgrounds were followed up for a 10-year period between 01 January 2008 and 31 December 2017. Data were linked to death certificate data from the Office of National Statistics to determine survival from dementia diagnosis. Standardised mortality ratios were calculated to estimate excess deaths in each ethnicity group as compared to the gender- and age-standardised population of England and Wales. We used Cox regression models to compare survival after dementia diagnosis across each ethnicity group. RESULTS: Mortality was elevated at least twofold across all ethnicity groups with dementia compared to the general population in England and Wales. Risk of death was lower in Black Caribbean, Black African, White Irish, and South Asian groups as compared to the White British population, even after adjusting for age, gender, neighbourhood-level deprivation, indicators of mental and physical comorbidities. Risk of death remained lower after additionally accounting for those who emigrated out of the cohort. CONCLUSIONS: While mortality in dementia is elevated across all ethnic groups as compared to the general population, reasons for longer survival in minority ethnic groups in the UK as compared to the White British group are unclear and merit further exploration. Implications of longer survival, including carer burden and costs, should be considered in policy and planning to ensure adequate support for families and carers of individuals with dementia.

Non-pharmacological interventions for the prevention of sexually transmitted infections (STIs) in older adults: A systematic review.

BACKGROUND: STIs in older adults (adults aged 50 years and older) are on the rise due to variable levels of sex literacy and misperceived susceptibility to infections, among other factors. We systematically reviewed evidence on the effect of non-pharmacological interventions for the primary prevention of sexually transmitted infections (STIs) and high-risk sexual behaviour in older adults. METHODS: We searched EMBASE, MEDLINE, PSYCINFO, Global Health and the Cochrane Library from inception until March 9th, 2022. We included RCTs, cluster-randomised trials, quasi-RCTs, interrupted time series (ITS) and controlled and uncontrolled before-and-after studies of non-pharmacological primary prevention interventions (e.g. educational and behaviour change interventions) in older adults, reporting either qualitative or quantitative findings. At least two review authors independently assessed the eligibility of articles and extracted data on main characteristics, risk of bias and study findings. Narrative synthesis was performed. RESULTS: Ten studies (two RCTs, seven quasi-experiment studies and one qualitative study) were found to be eligible for this review. These interventions were mainly information, education and communication activities (IECs) aimed at fostering participants' knowledge on STIs and safer sex, mostly focused on HIV. Most studies used self-reported outcomes measuring knowledge and behaviour change related to HIV, STIs and safer sex. Studies generally reported an increase in STI/HIV knowledge. However, risk of bias was high or critical across all studies. CONCLUSIONS: Literature on non-pharmacological interventions for older adults is sparse, particularly outside the US and for STIs other than HIV. There is evidence that IECs may improve short-term knowledge about STIs however, it is not clear this translates into long-term improvement or behaviour change as all studies included in this review had follow-up times of 3 months or less. More robust and higher-quality studies are needed in order to confirm the effectiveness of non-pharmacological primary prevention interventions for reducing STIs in the older adult population.

Access to Health Services in Older Minority Ethnic Groups with Dementia: A Systematic Review.

BACKGROUND/OBJECTIVES: While it is acknowledged that minority ethnic (ME) groups across international settings face barriers to accessing care for dementia, it is not clear whether ME groups access services less frequently as a result. The objective of this review is to examine whether ME groups have longer delays before accessing dementia/memory services, higher use of acute care and crisis services and lower use of routine care services based on existing literature. We also examined whether ME groups had higher dementia severity or lower cognition when presenting to memory services. DESIGN: Systematic review with narrative synthesis. SETTING: Nonresidential medical, psychiatric, memory, and emergency services. PARTICIPANTS: Twenty studies totaling 94,431 older adults with dementia or mild cognitive impairment. MEASUREMENTS: We searched Embase, Ovid MEDLINE, Global Health, and PsycINFO from inception to November 2018 for peer-reviewed observational studies which quantified ethnic minority differences in nonresidential health service use in people with dementia. Narrative synthesis was used to analyze findings. RESULTS: Twenty studies were included, mostly from the U.S. (n = 13), as well as the UK (n = 4), Australia (n = 1), Belgium (n = 1), and the Netherlands (n = 1). There was little evidence that ME groups in any country accessed routine care at different rates than comparison groups, although studies may have been underpowered. There was strong evidence that African American/Black groups had higher use of hospital inpatient services versus U.S. comparison groups. Primary care and emergency services were less well studied. Study quality was mixed, and there was a large amount of variability in the way ethnicity and service use outcomes were ascertained and defined. CONCLUSION: There is evidence that some ME groups, such as Black/African American groups in the U.S., may use more acute care services than comparison populations, but less evidence for differences in routine care use. Research is sparse, especially outside the U.S.

Outcomes tested in non-pharmacological interventions in mild cognitive impairment and mild dementia: a scoping review.

OBJECTIVES: Non-pharmacological treatments are an important aspect of dementia care. A wide range of interventions have been trialled for mild dementia and mild cognitive impairment (MCI). However, the variety of outcome measures used in these trials makes it difficult to make meaningful comparisons. The objective of this study is to map trends in which outcome measures are used in trials of non-pharmacological treatments in MCI and mild dementia. DESIGN: Scoping review. DATA SOURCES: EMBASE, PsychINFO, Medline and the Cochrane Register of Controlled Trials were searched from inception until February 2018. An additional search was conducted in April 2019 ELIGIBILITY: We included randomised controlled trials (RCTs) testing non-pharmacological interventions for people diagnosed with MCI or mild dementia. Studies were restricted to full RCTs; observational, feasibility and pilot studies were not included. CHARTING METHODS: All outcome measures used by included studies were extracted and grouped thematically. Trends in the types of outcome measures used were explored by type of intervention, country and year of publication. RESULTS: 91 studies were included in this review. We extracted 358 individual outcome measures, of which 78 (22%) were used more than once. Cognitive measures were the most frequently used, with the Mini-Mental State Examination being the most popular. CONCLUSIONS: Our findings highlight an inconsistency in the use of outcome measures. Cognition has been prioritised over other domains, despite previous research highlighting the importance of quality of life and caregiver measures. To ensure a robust evidence base, more research is needed to highlight which outcome measures should be used over others. PROSPERO REGISTRATION NUMBER: CRD42018102649.

Use of endothelial progenitor cell capture stent (Genous Bio-Engineered R Stent) during primary percutaneous coronary intervention in acute myocardial infarction: intermediate- to long-term clinical follow-up.

AIMS: We assessed the use of the endothelial progenitor cell (EPC) capture stent in primary percutaneous intervention in ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS: One hundred and twenty patients with acute STEMI without cardiogenic shock received 129 EPC capture stents. Procedural success was achieved in 95% of patients. Dual antiplatelet therapy was given for a month and statin therapy started immediately after the procedure. The study end points are major adverse cardiac events inhospital and at 30 days, 6 months, and 1 year. Hypertension was present in 47.5% and diabetes mellitus in 30% of the patients. The left anterior descending artery was the treated artery in 54% of the patients. Mean lesion length was 17.4 +/- 7.15 mm with mean reference vessel diameter of 3.18 +/- 0.6 mm. Platelet glycoprotein IIb/IIIa inhibitor was used in 14% of patients and 58% had thrombosuction before stent implantation. Ninety-five percent of patients achieved Thrombolysis in Myocardial Infarction 3 flow with cumulative major adverse cardiac event rate at 1.6% inhospital, 4.2% at 30 days, 5.8% at 6 months, and 9.2% at 1 year. There was 1 patient each with acute and subacute stent thrombosis but no incidence of late stent thrombosis. CONCLUSION: Using EPC capture stent during primary percutaneous coronary intervention for STEMI is feasible and safe.

Effectiveness and safety of the genous endothelial progenitor cell-capture stent in acute ST-elevation myocardial infarction.

The endothelial progenitor cell (EPC)-capture stent promotes endothelialization and preliminary studies have suggested its safety and feasibility in ST-elevation myocardial infarction (STEMI). Detailed late clinical follow-up and angiographic analyses are, however, limited. We sought to determine late angiographic and clinical outcomes of the Genous EPC-capture stent in primary angioplasty. EPC-capture stents were implanted during primary angioplasty in 489 consecutive patients presenting with STEMI from 2004 through 2008. The first 100 consenting patients undergoing successful stent implantation scheduled to undergo relook coronary angiography at 6 to 12 months were enrolled. Ninety-five patients with 96 lesions were analyzed independently. Mean duration of follow-up coronary angiography was 245 days. In-stent late luminal loss measured 0.87 ± 0.67 mm. Binary restenosis (defined as >50% diameter stenosis) was 28%, with diffuse in-stent restenosis (Mehran class II) as the predominant pattern. Of 27 patients with binary restenosis, 14 (52%) were symptomatic, with 10 patients undergoing target lesion revascularization. Asymptomatic patients had significantly larger reference vessel and in-stent minimal luminal diameters (2.77 ± 0.39 vs 2.54 ± 0.44 mm, p = 0.040; 2.74 ± 0.34 vs 2.31 ± 0.72 mm, p = 0.004, respectively). Follow-up late loss and diameter stenoses were also in favor of the asymptomatic group. Major adverse cardiac event rate was 16% at a mean follow-up of 34 months. There were no cases of Academic Research Consortium-defined stent thrombosis. In conclusion, implantation of the EPC-capture stent during primary angioplasty is associated with a favorable late clinical outcome but with higher than anticipated angiographic late loss.

Clinical experience of StarClose vascular closure device in patients with first and recurrent femoral punctures.

OBJECTIVE: We present our clinical experience of StarClose in patients undergoing coronary interventions, including its use in patients after repeated puncture of the same femoral access site. BACKGROUND: The StarClose is a novel vascular closure device that deploys a small, flexible, circumferential nitinol clip onto the femoral artery surface. METHODS: In this study, 103 consecutive patients (24% with repeated punctures) who underwent percutaneous coronary intervention and received a StarClose were followed up prospectively. The patients were assessed for vascular complications prior to hospital discharge. Device success, based on time-to-hemostasis, was divided into (1) immediate success: hemostasis achieved immediately after StarClose deployment without the need for adjunctive manual compression, (2) partial success: occurrence of minor oozing after StarClose deployment and hemostasis achieved after <3 minutes of manual compression, and (3) device failure: need for adjunctive manual compression for >3 minutes. RESULTS: Immediate success, partial success, and device failure rates were 74% (n = 68), 16% (n = 15), and 10% (n = 9), respectively. There were no major complications attributable to the StarClose device. There were 10 (9.7%) cases of minor complications; all were recurrent wound bleeding requiring manual compression in the wards. Among these 10 cases of recurrent bleeding, 5 (50%) had initial device success (immediate success, n = 2, partial success, n = 3) in the catheterization laboratory. The risk for recurrent bleeding was 2.9% after immediate device success and 20.0% after partial device success. CONCLUSION: Our study found no major complications but a 10% failure rate and a 9.7% rate of minor complications. Close surveillance is important as there is a risk for recurrent bleeding, especially in patients with partial device success as defined in this report.

Pretreatment with intracoronary adenosine reduces the incidence of myonecrosis after non-urgent percutaneous coronary intervention: a prospective randomized study.

AIMS: We sought to investigate the effect of adenosine pretreatment on the incidence of myonecrosis after non-urgent percutaneous coronary intervention (PCI). METHODS AND RESULTS: This was a prospective, randomized, open-label study. Patients who were scheduled for non-urgent PCI in de novo native coronary arteries were eligible. All patients were pretreated with aspirin and clopidogrel. Myonecrosis was measured by creatine kinase-myocardial band (CK-MB) elevation after PCI. A total of 62 patients were randomized into the adenosine (n = 31) or standard (n = 31) group. The adenosine group received 50 microg adenosine bolus before wiring of each lesion, whereas the standard group did not. Post-PCI myonecrosis occurred more frequently in the standard group (39 vs. 13%, OR 0.23, 95% CI 0.05-0.95, P = 0.020). After adjustment for drug-eluting stent implantation, multi-vessel stenting, and elevated baseline troponin, the OR was 0.19 (95% CI 0.05-0.72, P = 0.017). The median peak values of CK-MB in the adenosine and standard groups were 2 and 4 microg/L, respectively (P = 0.033). The adjusted difference was 1.95 microg/L (95% CI 0.13-3.77, P = 0.037). The incidences of myocardial infarction (>3 x CK-MB) were 6 and 16% in the adenosine and standard groups, respectively (OR 0.36; 95% CI 0.03-2.46, P = 0.229). CONCLUSION: Pretreatment with 50 microg of adenosine decreases the incidence of myonecrosis after non-urgent PCI compared with that without pretreatment.
