RESUMO

INTRODUCTION: Sodium-glucose cotransporter 2 (SGLT2) inhibitors exhibit potential benefits in reducing dementia risk, yet the optimal beneficiary subgroups remain uncertain. METHODS: Individuals with type 2 diabetes (T2D) initiating either SGLT2 inhibitor or sulfonylurea were identified from OneFlorida+ Clinical Research Network (2016-2022). A doubly robust learning was deployed to estimate risk difference (RD) and 95% confidence interval (CI) of all-cause dementia. RESULTS: Among 35,458 individuals with T2D, 1.8% in the SGLT2 inhibitor group and 4.7% in the sulfonylurea group developed all-cause dementia over a 3.2-year follow-up, yielding a lower risk for SGLT2 inhibitors (RD, -2.5%; 95% CI, -3.0% to -2.1%). Hispanic ethnicity and chronic kidney disease were identified as the two important variables to define four subgroups in which RD ranged from -4.3% (-5.5 to -3.2) to -0.9% (-1.9 to 0.2). DISCUSSION: Compared to sulfonylureas, SGLT2 inhibitors were associated with a reduced risk of all-cause dementia, but the association varied among different subgroups. HIGHLIGHTS: New users of sodium-glucose cotransporter 2 (SGLT2) inhibitors were significantly associated with a lower risk of all-cause dementia as compared to those of sulfonylureas. The association varied among different subgroups defined by Hispanic ethnicity and chronic kidney disease. A significantly lower risk of Alzheimer's disease and vascular dementia was observed among new users of SGLT2 inhibitors compared to those of sulfonylureas.

RESUMO

INTRODUCTION: Magnetic resonance imaging (MRI) biomarkers are needed for indexing early biological stages of Alzheimer's disease (AD), such as plasma amyloid-ß (Aß42/40) positivity in Aß positron emission tomography (PET) negative individuals. METHODS: Diffusion free-water (FW) MRI was acquired in individuals with normal cognition (NC) and mild cognitive impairment (MCI) with Aß plasma-/PET- (NC = 22, MCI = 60), plasma+/PET- (NC = 5, MCI = 20), and plasma+/PET+ (AD dementia = 21) biomarker status. Gray and white matter FW and fractional anisotropy (FAt) were compared cross-sectionally and the relationships between imaging, plasma and PET biomarkers were assessed. RESULTS: Plasma+/PET- demonstrated increased FW (24 regions) and decreased FAt (66 regions) compared to plasma-/PET-. FW (16 regions) and FAt (51 regions) were increased in plasma+/PET+ compared to plasma+/PET-. Composite brain FW correlated with plasma Aß42/40 and p-tau181. DISCUSSION: FW imaging changes distinguish plasma Aß42/40 positive and negative groups, independent of group differences in cognitive status, Aß PET status, and other plasma biomarkers (i.e., t-tau, p-tau181, glial fibrillary acidic protein, neurofilament light). HIGHLIGHTS: Plasma Aß42/40 positivity is associated with brain microstructure decline. Plasma+/PET- demonstrated increased FW in 24 total GM and WM regions. Plasma+/PET- demonstrated decreased FAt in 66 total GM and WM regions. Whole-brain FW correlated with plasma Aß42/40 and p-tau181 measures. Plasma+/PET- demonstrated decreased cortical volume and thickness.

RESUMO

INTRODUCTION: Alzheimer's disease studies often lack ethnic diversity. METHODS: We evaluated associations between plasma biomarkers commonly studied in Alzheimer's (p-tau181, GFAP, and NfL), clinical diagnosis (clinically normal, amnestic MCI, amnestic dementia, or non-amnestic MCI/dementia), and Aß-PET in Hispanic and non-Hispanic older adults. Hispanics were predominantly of Cuban or South American ancestry. RESULTS: Three-hundred seventy nine participants underwent blood draw (71.9 ± 7.8 years old, 60.2% female, 57% Hispanic of which 88% were Cuban or South American) and 240 completed Aß-PET. P-tau181 was higher in amnestic MCI (p = 0.004, d = 0.53) and dementia (p < 0.001, d = 0.97) than in clinically normal participants and discriminated Aß-PET[+] and Aß-PET[-] (AUC = 0.86). P-tau181 outperformed GFAP and NfL. There were no significant interactions with ethnicity. Among amnestic MCI, Hispanics had lower odds of elevated p-tau181 than non-Hispanic (OR = 0.41, p = 0.006). DISCUSSION: Plasma p-tau181 informs etiological diagnosis of cognitively impaired Hispanic and non-Hispanic older adults. Hispanic ethnicity may relate to greater likelihood of non-Alzheimer's contributions to memory loss. HIGHLIGHTS: Alzheimer's biomarkers were measured in Hispanic and non-Hispanic older adults. Plasma p-tau181 related to amnestic cognitive decline and brain amyloid burden. AD biomarker associations did not differ between Hispanic and non-Hispanic ethnicity. Hispanic individuals may be more likely to have non-Alzheimer causes of memory loss.

RESUMO

OBJECTIVE: While declarative learning is dependent on the hippocampus, procedural learning and repetition priming can operate independently from the hippocampus, making them potential targets for behavioral interventions that utilize non-declarative memory systems to compensate for the declarative learning deficits associated with hippocampal insult. Few studies have assessed procedural learning and repetition priming in individuals with amnestic mild cognitive impairment (aMCI). METHOD: This study offers an overview across declarative, conceptual repetition priming, and procedural learning tasks by providing between-group effect sizes and Bayes Factors (BFs) comparing individuals with aMCI and controls. Seventy-six individuals with aMCI and 83 cognitively unimpaired controls were assessed. We hypothesized to see the largest differences between individuals with aMCI and controls on declarative learning, followed by conceptual repetition priming, with the smallest differences on procedural learning. RESULTS: Consistent with our hypotheses, we found large differences between groups with supporting BFs on declarative learning. For conceptual repetition priming, we found a small-to-moderate between-group effect size and a non-conclusive BF somewhat in favor of a difference between groups. We found more variable but overall trivial differences on procedural learning tasks, with inconclusive BFs, in line with expectations. CONCLUSIONS: The current results suggest that conceptual repetition priming does not remain intact in individuals with aMCI while procedural learning may remain intact. While additional studies are needed, our results contribute to the evidence-base that suggests that procedural learning may remain spared in aMCI and helps inform behavioral interventions that aim to utilize procedural learning in this population.

RESUMO

Persons with amnestic Mild Cognitive Impairment (aMCI) are at risk for experiencing changes in their daily functioning due to their memory impairment. The Memory Support System (MSS), a compensatory calendaring system, was developed to support functional independence in persons with aMCI (pwaMCI). This cross-sectional study examined procedural learning, declarative learning, and working memory as predictors of MSS learning efficiency in pwaMCI. Sixty pwaMCI participated in MSS training. The Serial Reaction Time Test and Mirror Tracing Test were used to assess procedural learning. The Rey Auditory Verbal Learning Test and CogState One Card Learning were used to assess declarative learning and the CogState One Back task was used to assess working memory. Multiple regression analyses were conducted to assess if procedural learning, declarative learning, and working memory predicted MSS learning efficiency. This study showed that declarative learning predicted MSS learning efficiency in pwaMCI, with less consistent results for procedural learning and non-significant results for working memory. Findings suggest that success in teaching compensatory tools is greater when training is offered in early aMCI before declarative learning skill is fully lost. Future studies should assess additional strategies to facilitate MSS learning in advanced aMCI.

RESUMO

INTRODUCTION: This study aims to explore machine learning (ML) methods for early prediction of Alzheimer's disease (AD) and related dementias (ADRD) using the real-world electronic health records (EHRs). METHODS: A total of 23,835 ADRD and 1,038,643 control patients were identified from the OneFlorida+ Research Consortium. Two ML methods were used to develop the prediction models. Both knowledge-driven and data-driven approaches were explored. Four computable phenotyping algorithms were tested. RESULTS: The gradient boosting tree (GBT) models trained with the data-driven approach achieved the best area under the curve (AUC) scores of 0.939, 0.906, 0.884, and 0.854 for early prediction of ADRD 0, 1, 3, or 5 years before diagnosis, respectively. A number of important clinical and sociodemographic factors were identified. DISCUSSION: We tested various settings and showed the predictive ability of using ML approaches for early prediction of ADRD with EHRs. The models can help identify high-risk individuals for early informed preventive or prognostic clinical decisions.

RESUMO

OBJECTIVES: Describe health concerns of Black Americans as they age and what influences their participation in aging and clinical research. METHODS: Fifty participants attended focus groups and completed questionnaires to identify barriers to research participation and attitudes toward dementia screening. Bivariate correlations explored associations between barriers to research participation and attitudes toward dementia screening. RESULTS: Cancer, hereditary conditions, vascular conditions, memory disorders, and psychological disorders were the greatest health concerns. Time demands, mistrust, lack of knowledge about potential research, and stigma were identified as barriers for research participation. Incentives, better understanding of how proposed research will benefit the community, lifestyle modification studies, active presence of principal researchers/clinicians, and community investment were identified as factors to improve participation. Questionnaires revealed mistrust and religious beliefs to be among the primary barriers. Attitudes toward dementia screening reflected perceived stigma, suffering, and subsequent loss of independence. Higher barriers to participation were associated with perceived stigma and loss of independence related to dementia screening. CONCLUSIONS: Successfully recruiting Black Americans for aging and clinical research remains a challenge. This study identifies barriers to participation and offers suggestions for planning and recruitment.

RESUMO

The literature on repetition priming in Alzheimer's disease (AD) is inconsistent, with some findings supporting spared priming while others do not. Several factors may explain these inconsistencies, including AD severity (e.g., dementia vs. Mild Cognitive Impairment; MCI) and priming paradigm-related characteristics. This systematic review and meta-analysis provides a quantitative summary of repetition priming in AD. We examined the between-group standard mean difference comparing repetition priming in AD dementia or amnestic MCI (aMCI; presumably due to AD) to controls. Thirty-two studies were selected, including 590 individuals with AD dementia, 267 individuals with amnestic MCI, and 703 controls. Our results indicated that both individuals with aMCI and AD dementia perform worse on repetition priming tasks than cognitively older adults. Paradigm-related moderators suggested that the effect size between studies comparing the combined aMCI or AD dementia group to cognitively healthy older adults was the highest for paradigms that required participants to produce, rather than identify, primes during the test phase. Our results further suggested that priming in AD is impaired for both conceptual and perceptual priming tasks. Lastly, while our results suggested that priming in AD is impaired for priming tasks that require deep processing, we were unable to draw firm conclusions about whether priming is less impaired in aMCI or AD dementia for paradigms that require shallow processing.

RESUMO

The Memory Support System (MSS) is the memory compensation tool used in the HABIT Healthy Action to Benefit Independence and Thinking® Program. People diagnosed with mild cognitive impairment (pwMCI; n = 153) participated in this cognitive rehabilitative programme with a partner. We first aimed to determine if prior research on the positive impact of higher baseline cognitive status on successful MSS learning would be replicated in a new sample. We further evaluated the impact of the pwMCI's and partner's personality traits, as measured by the Ten Item Personality Inventory, on successful learning. Better global cognitive status was again shown to increase the odds for MSS learning success. In terms of personality, the highest odds of learning success occurred when the pwMCI was high in Openness to Experience (OR = 5.43), followed by high partner Openness (OR = 2.53) or high Openness in both the pwMCI and partner (OR = 2.31). In sum, when the pwMCI possessed both better cognitive status and openness to new experience they were better able to master a cognitive rehabilitation tool for MCI.

RESUMO

BACKGROUND: Patients commonly display aggressive and violent behaviors toward nursing staff, contributing to severe consequences. Healthcare institutions must develop and implement systems addressing this global safety problem. AIM: To improve clinical practice safety for inpatient acute care settings by providing healthcare teams throughout a large academic medical center with a Behavioral Emergency Response Team (BERT) program, that is, a system for reporting and de-escalating aggressive patient encounters. METHODS: This descriptive quality improvement process took place within two inpatient acute care departments using simulation-based training, patient safety rounds, and a BERT activation system. Participant groups included nursing personnel who completed a baseline survey (n = 302), telecommunication dispatchers (n = 20), BERT responders (n = 78), and bedside nursing staff (n = 43) recipients of BERT program resources. Methods included a baseline questionnaire, pre- and post-intervention surveys, formal reports of aggressive patient encounters, documentation from patient safety rounds, and records of activated BERT responses. Data analysis included descriptive statistics, boxplots, and the Wilcoxon signed-rank test. RESULTS: This project mitigated patient aggression episodes by successfully designing and implementing an evidence-based BERT program. Findings suggested bedside nursing program participants felt more confident and capable of managing aggressive patient behaviors. A strong partnership between security officers and nursing staff limited the risk of harm to clinical staff by identifying and intervening with 41 potentially aggressive patients. Finally, formal reports of patient aggression episodes did not increase during this project, which may have indicated early prevention and detection of aggression while reflecting the broader problem of aggression under-reporting in nursing. LINKING EVIDENCE TO ACTION: Healthcare organizations need to have robust systems to manage aggressive patient encounters. Comprehensive strategies for managing patient aggression include simulation-based training, the use of BERT responders, and a strong partnership between nursing and security officer teams.

RESUMO

The notion that procedural learning and memory is spared in Alzheimer's disease (AD) has important implications for interventions aiming to build on intact cognitive functions. However, despite these clinical implications, there are mixed findings in the literature about whether or not procedural learning remains intact. This meta-analysis examines the standard mean difference of all published studies regarding procedural learning in AD dementia or amnestic Mild Cognitive Impairment (aMCI) compared to cognitively healthy older adults. Additionally, we conducted statistical equivalence analyses. Our systematic review showed that only a limited number of studies (k = 17) have compared procedural learning between individuals with aMCI or AD dementia and healthy controls. Our meta-analysis, which synthesized these studies, demonstrated that while procedural learning performance was not statistically equivalent between individuals with aMCI or AD dementia, and healthy older adults, the difference was clinically and statistically trivial. Although larger studies are needed, the present findings suggest that procedural learning does appear to remain spared in aMCI and AD dementia.

RESUMO

We introduce a JINS special section inspired by a symposium presented at INS 2020 in Denver. The symposium was entitled Truly Cross-fit: The Association of Exercise and Cognitive Reserve. The collection of papers herein spans diverse methods, a range of developmental and clinical conditions, and a variety of outcomes all reflecting on the association of exercise and cognition-related outcomes. Taken together, the studies in this Special Section direct us to the variety of dimensions to be considered in understanding this association including what mode, intensity, duration, and timing of physical activity and aspects of age, sex, genetics, baseline characteristics, and disease status moderate these findings. We hope this Special Section will not only provide a framing for important future research on exercise and clinical outcomes but also inspiration to pursue them.

RESUMO

OBJECTIVES: Lifestyle modifications for those with mild cognitive impairment (MCI) may promote functional stability, lesson disease severity, and improve well-being outcomes such as quality of life. The current analysis of our larger comparative effectiveness study evaluated which specific combinations of lifestyle modifications offered as part of the Mayo Clinic Healthy Action to Benefit Independence in Thinking (HABIT) program contributed to the least functional decline in people with MCI (pwMCI) over 18 months. METHODS: We undertook to compare evidence-based interventions with one another rather than to a no-treatment control group. The interventions were five behavioral treatments: computerized cognitive training (CCT), yoga, Memory Support System (MSS) training, peer support group (SG), and wellness education (WE), each delivered to both pwMCI and care partners, in a group-based program. To compare interventions, we randomly withheld one of the five HABIT® interventions in each of the group sessions. We conducted 24 group sessions with between 8 and 20 pwMCI-partner dyads in a session. RESULTS: Withholding yoga led to the greatest declines in functional ability as measured by the Functional Activities Questionnaire and Clinical Dementia Rating. In addition, memory compensation (calendar) training and cognitive exercise appeared to have associations (moderate effect sizes) with better functional outcomes. Withholding SG or WE appeared to have little effect on functioning at 18 months. CONCLUSIONS: Overall, these results add to the growing literature that physical exercise can play a significant and lasting role in modifying outcomes in a host of medical conditions, including neurodegenerative diseases.

RESUMO

BACKGROUND: Patient-centered care requires understanding patient preferences and needs, but research on the clinical care preferences of individuals living with dementia and caregivers is sparse, particularly in dementia with Lewy bodies (DLB). METHODS: Investigators conducted telephone interviews with individuals living with DLB and caregivers from a Lewy body dementia specialty center. Interviews employed a semistructured questionnaire querying helpful aspects of care and unmet needs. Investigators used a qualitative descriptive approach to analyze transcripts and identify themes. RESULTS: Twenty individuals with DLB and 25 caregivers participated. Twenty-three of the caregivers were spouses, 2 were daughters. Aspects of clinical care valued by individuals with DLB and caregivers included clinician time, diagnosis, education, symptom management, communication, and caring staff. Unmet needs or challenges included patient/caregiver education, education of nonspecialist clinicians and community care providers, scheduling difficulties, caregiver support, financial concerns, assistance with advance care planning and finding local resources, and effective treatments for DLB symptoms. CONCLUSION AND RELEVANCE: Improving care for individuals with DLB and their families will require a multipronged strategy including education for nonspecialist care providers, increasing specialty care access, improved clinical care services, research to support disease prognosis and treatment decisions, and local and national strategies for enhanced caregiver support.

RESUMO

OBJECTIVES: We adapted a self-efficacy measure for managing chronic illness to be specific to persons with mild cognitive impairment (pwMCI). The aim of this study was to investigate the psychometric properties of the scale, the self-efficacy for managing MCI scale, for use in research. METHODS: Analyses involved data from pwMCI enrolled in a behavioral intervention study that completed the measure five times from intervention enrollment to 18-month post-intervention. Factor structure, construct validity, internal consistency, and test-retest reliability were analyzed. RESULTS: Factor analysis identified two factors, related to self-efficacy for daily activities and managing MCI, which corresponded with domains from the original chronic illness self-efficacy scale. Consistent with prior research, construct validity analysis suggested an association between memory-loss self-efficacy and psychosocial distress, but not cognitive or functional ability. Further analyses supported the scale's internal and test-retest reliability. CONCLUSIONS: Currently, no "gold standard" scale of memory-loss self-efficacy for pwMCI exists, despite the positive impact self-efficacy may have on modifiable health behaviors. Overall, results supported the notion that the scale is a valid and reliable measure of memory-loss self-efficacy for pwMCI.

RESUMO

This study aimed to identify predictors of learning and adherence to a previously validated compensatory calendar and note-taking system (Memory Support System; MSS) in persons with amnestic mild cognitive impairment (aMCI). Age, education, global cognition, depression, and memory-related self-efficacy were studied as predictors of individuals' ability to learn the use of the MSS during the two-week training and of their adherence to the MSS 6, 12, and 18 months after training. How well an individual was able to learn the use of the MSS was itself examined as a predictor of adherence. Two-hundred-and-fifteen older adults with aMCI and their study partners (e.g., spouse, adult child) received MSS training one-hour daily for 10 days. Ordinal logistic regression analyses indicated that (1) global cognition predicted MSS learning at end of training, and (2) MSS learning at end of trainng predicted MSS adherence at 6, 12, and 18 months post-training. The current study suggests that offering compensatory strategies as early as possible for those with MCI might be of most benefit, and might have implications for long-term adherence.

RESUMO

OBJECTIVE: The presence of sub-epidermal moisture (SEM) over a bony prominence is indicative of incipient pressure ulcer (pressure injury/decubitus/bedsore) (PU). Early identification of patients at increased risk of PU can prompt interventions that reduce the incidence and severity of hospital (or community)-acquired PUs (HAPUs). This study evaluated the clinical utility of a SEM Scanner device in HAPU management. METHOD: The study used a pragmatic 'real-world' approach. HAPU data before and during SEM Scanner use were obtained through routine audit. Patients had regular visual and daily SEM Scanner skin assessments over the sacrum and heels. Nursing care otherwise followed standard of care according to the established protocols of individual participating sites. HAPU incidence rates were determined and feedback gathered from health professionals on how the device influenced HAPU-related clinical decision-making. RESULTS: There were 15 participating sites: 13 acute care, one palliative care and one community care setting. The sample size was 1478 patients. All sites reported a substantial reduction in mean HAPU incidence: 87.2% in acute care settings; 46.7% in the palliative care setting and 26.7% in the community care setting. A 100% incidence reduction was reported in 10 (66.7%) sites. In the palliative care setting, SEM Scanner results changed HAPU-related clinical decision-making for 40% of patients scanned. The community care site demonstrated a 82% change in clinical decision-making. CONCLUSION: In this study, SEM analysis fitted seamlessly into routine skin assessment and enabled early identification of increased risk of tissue damage, with clinically important reductions in the incidence of HAPU across all participating sites.

RESUMO

Professional autonomy has come under greater scrutiny due to managerialism, consumerism, information and communication technologies (ICT), and the changing composition of professions themselves. This scrutiny is often portrayed as a tension between professional and managerial logics. Recently, medical autonomy has increasingly been shaped in terms of transparency, where publication of clinical performance (via ICT) might be a more pervasive form of surveillance. Such transparency may have the potential for a more explicit managerial logic but is contested by clinicians. This paper applies notions of surveillance to public reporting of cardiac surgery, involving the online publication of mortality rates of named surgeons. It draws on qualitative data from a case-study of cardiac surgeons in one hospital, incorporating interviews with health care managers and national policymakers in England. We examine how managerial logics are mediated by professional autonomy, generating patterns of enrolment, resistance and reactivity to public reporting. The managerial 'gaze' of public reporting is becoming widespread but the surgical specialty is accommodating it, leading to a re-assertion of knowledge, based on professional definitions. The paper assesses whether this form of surveillance is challenging to or being assimilated by the medical profession, thereby recasting the profession itself.

RESUMO

OBJECTIVE: An in-practice evaluation of an sub-epidermal moisture (SEM) scanner, to detect non-visible pressure damage, allowing appropriate, targeted pressure ulcer (PU) prevention interventions. METHOD: The evaluation included patients on a single medical-surgical ward over a period of two months. RESULTS: The evaluation included 35 patients. The outcomes of the evaluation suggest that the SEM scanner provided objective evidence that both the interventions being employed and the increase in repositioning and assessment prevented further incipient skin damage. CONCLUSION: We conclude that the early detection of non-visible tissue injury using the SEM scanner as an adjunct to the usual PU risk assessment strategies can reduce PU incidence, leading to improved patient outcomes and released productivity.

RESUMO

Despite the understanding that wounds are a common problem affecting the individual, the health service and society as a whole, there continues to be a lack of a systematic, structured, evidence-based approach to wound management. The TIME principle was first published in 2003, 1 and has since been integrated by many into clinical practice and research. However, this tool has been criticised for its tendency to focus mainly on the wound rather than on the wider issues that the patient is presenting with. At an expert meeting held in London in 2018, this conundrum was addressed and the TIME clinical decision support tool (CDST) was elaborated upon. This article introduces the TIME CDST, explains why it is required and describes how its use is likely to benefit patients, clinicians and health-service organisations. It also explores the framework in detail, and shows why this simple and accessible framework is robust enough to facilitate consistency in the delivery of wound care and better patient outcomes.
