This study serves as an exemplar to demonstrate the scalability of a research approach using survival analysis applied to general practice electronic health record data from multiple sites. Collection of these data, the subsequent analysis, and the preparation of practice-specific reports were performed using a bespoke distributed data collection and analysis software tool.
Background:
Statins are a very commonly prescribed medication, yet there is a paucity of evidence for their benefits in older patients. We examine the relationship between statin prescriptions for general practice patients over 75 and all-cause mortality.
Methods:
We carried out a retrospective cohort study using survival analysis applied to data extracted from the electronic health records of five Australian general practices.
Findings:
The data from 8025 patients were analysed. The median duration of follow-up was 6.48 years. Overall, 52 015 patient-years of data were examined, and the outcome of death from any cause was measured in 1657 patients (21%), with the remainder being censored. Adjusted all-cause mortality was similar for participants not prescribed statins versus those who were (HR 1.05, 95% CI 0.92–1.20, P = 0.46), except for patients with diabetes for whom all-cause mortality was increased (HR = 1.29, 95% CI: 1.00–1.68, P = 0.05). In contrast, adjusted all-cause mortality was significantly lower for patients deprescribed statins compared to those who were prescribed statins (HR 0.81, 95% CI 0.70–0.93, P < 0.001), including among females (HR = 0.75, 95% CI: 0.61–0.91, P < 0.001) and participants treated for secondary prevention (HR = 0.72, 95% CI: 0.60–0.86, P < 0.001). This study demonstrated the scalability of a research approach using survival analysis applied to general practice electronic health record data from multiple sites. We found no evidence of increased mortality due to statin-deprescribing decisions in primary care.
Symptom clustering research provides a unique opportunity for understanding complex medical conditions. The objective of this study was to apply a variable-centered analytic approach to understand how symptoms may cluster together, within and across domains of functioning in mild cognitive impairment (MCI) and dementia, to better understand these conditions and potential etiological, prevention, and intervention considerations.
Method:
Cognitive, motor, sensory, emotional, and social measures from the NIH Toolbox were analyzed using exploratory factor analysis (EFA) from a dataset of 165 individuals with a research diagnosis of either amnestic MCI or dementia of the Alzheimer’s type.
Results:
The six-factor EFA solution described here primarily replicated the intended structure of the NIH Toolbox with a few deviations, notably sensory and motor scores loading onto factors with measures of cognition, emotional, and social health. These findings suggest the presence of cross-domain symptom clusters in these populations. In particular, negative affect, stress, loneliness, and pain formed one unique symptom cluster that bridged the NIH Toolbox domains of physical, social, and emotional health. Olfaction and dexterity formed a second unique cluster with measures of executive functioning, working memory, episodic memory, and processing speed. A third novel cluster was detected for mobility, strength, and vision, which was considered to reflect a physical functioning factor. Somewhat unexpectedly, the hearing test included did not load strongly onto any factor.
Conclusion:
This research presents a preliminary effort to detect symptom clusters in amnestic MCI and dementia using an existing dataset of outcome measures from the NIH Toolbox.
Circadian rhythms exhibit many alterations during the normal aging process and more severe disruptions are evident in age-related neurological conditions such as Alzheimer’s disease (AD). Indeed, evidence suggests that circadian rhythm alterations increase susceptibility to AD and conversely that the progressive neuropathological features of AD such as amyloid-beta accumulation further exacerbate circadian rhythm disruption. Impairments in neural function in the master circadian pacemaker in the hypothalamic suprachiasmatic nucleus underlie age- and AD-related alterations in circadian rhythms. Deficits in expression of the clock genes constituting the molecular pathways controlling circadian rhythms also contribute to circadian rhythm impairments and neurodegeneration in senescence and AD. This chapter describes the mechanisms underlying age- and AD-related alterations in circadian rhythms as well as their possible causes and potential strategies for their amelioration.
Neuropsychologists have difficulty detecting cognitive decline in high-functioning older adults because greater neurological change must occur before cognitive performances are low enough to indicate decline or impairment. For high-functioning older adults, early neurological changes may correspond with subjective cognitive concerns and an absence of high scores. This study compared high-functioning older adults with and without subjective cognitive concerns, hypothesizing those with cognitive concerns would have fewer high scores on neuropsychological testing and lower frontoparietal network volume, thickness, and connectivity.
Method:
Participants had high estimated premorbid functioning (e.g., estimated intelligence ≥75th percentile or college-educated) and were divided based on subjective cognitive concerns. Participants with cognitive concerns (n = 35; 74.0 ± 9.6 years old, 62.9% female, 94.3% White) and without cognitive concerns (n = 33; 71.2 ± 7.1 years old, 75.8% female, 100% White) completed a neuropsychological battery of memory and executive function tests and underwent structural and resting-state magnetic resonance imaging, calculating frontoparietal network volume, thickness, and connectivity.
Results:
Participants with and without cognitive concerns had comparable numbers of low test scores (≤16th percentile), p = .103, d = .40. Participants with cognitive concerns had fewer high scores (≥75th percentile), p = .004, d = .71, and lower mean frontoparietal network volumes (left: p = .004, d = .74; right: p = .011, d = .66) and cortical thickness (left: p = .010, d = .66; right: p = .033, d = .54), but did not differ in network connectivity.
Conclusions:
Among high-functioning older adults, subjective cognitive decline may correspond with an absence of high scores on neuropsychological testing and underlying changes in the frontoparietal network that would not be detected by a traditional focus on low cognitive test scores.
Diets with a low proportion of energy from protein have shown to cause overconsumption of non-protein energy, known as Protein Leverage. Older adults are susceptible to nutritional inadequacy. The aim was to investigate associations between protein to non-protein ratio (P:NP) and intakes of dietary components and assess the nutritional adequacy of individuals aged 65–75 years from the Nutrition for Healthy Living (NHL) Study.
Design:
Cross-sectional. Nutritional intakes from seven-day weighed food records were compared with the Nutrient Reference Values for Australia and New Zealand, Australian Guide to Healthy Eating, Australian Dietary Guidelines and World Health Organisation Free Sugar Guidelines. Associations between P:NP and intakes of dietary components were assessed through linear regression analyses.
Setting:
NHL Study.
Participants:
113 participants.
Results:
Eighty-eight (59 female and 29 male) with plausible dietary data had a median (interquartile range) age of 69 years (67–71), high education level (86 %) and sources of income apart from the age pension (81 %). Substantial proportions had intakes below recommendations for dairy and alternatives (89 %), wholegrain (89 %) and simultaneously exceeded recommendations for discretionary foods (100 %) and saturated fat (92 %). In adjusted analyses, P:NP (per 1 % increment) was associated with lower intakes of energy, saturated fat, free sugar and discretionary foods and higher intakes of vitamin B12, Zn, meat and alternatives, red meat, poultry and wholegrain % (all P < 0·05).
Conclusions:
Higher P:NP was associated with lower intakes of energy, saturated fat, free sugar and discretionary. Our study revealed substantial nutritional inadequacy in this group of higher socio-economic individuals aged 65–75 years.
The Harmonized Cognitive Assessment Protocol (HCAP) describes an assessment battery and a family of population-representative studies measuring neuropsychological performance. We describe the factorial structure of the HCAP battery in the US Health and Retirement Study (HRS).
Method:
The HCAP battery was compiled from existing measures by a cross-disciplinary and international panel of researchers. The HCAP battery was used in the 2016 wave of the HRS. We used factor analysis methods to assess and refine a theoretically driven single and multiple domain factor structure for tests included in the HCAP battery among 3,347 participants with evaluable performance data.
Results:
For the eight domains of cognitive functioning identified (orientation, memory [immediate, delayed, and recognition], set shifting, attention/speed, language/fluency, and visuospatial), all single factor models fit reasonably well, although four of these domains had either 2 or 3 indicators where fit must be perfect and is not informative. Multidimensional models suggested the eight-domain model was overly complex. A five-domain model (orientation, memory delayed and recognition, executive functioning, language/fluency, visuospatial) was identified as a reasonable model for summarizing performance in this sample (standardized root mean square residual = 0.05, root mean square error of approximation = 0.05, confirmatory fit index = 0.94).
Conclusions:
The HCAP battery conforms adequately to a multidimensional structure of neuropsychological performance. The derived measurement models can be used to operationalize notions of neurocognitive impairment, and as a starting point for prioritizing pre-statistical harmonization and evaluating configural invariance in cross-national research.
Hearing impairment in older adults may affect cognitive function and increase the risk of dementia. Most cognitive tests are delivered auditorily, and individuals with hearing loss may fail to hear verbal instructions. Greater listening difficulty and fatigue in acoustic conditions may impact test performance. This study aimed to examine the effect of decreased audibility on cognitive screening test performance in older adults.
Method
Older adults (n = 63) with different levels of hearing loss completed a standard auditory Mini-Mental State Examination test and a written version of the test.
Results
Individuals with moderate to moderately severe hearing loss (41–70 dB) performed significantly better on the written (24.34 ± 4.90) than on the standard test (22.55 ± 6.25), whereas scores were not impacted for mild hearing loss (less than 40 dB).
Conclusion
Hearing evaluations should be included in cognitive assessment, and test performance should be carefully interpreted in individuals with hearing loss to avoid overestimating cognitive decline.
Prevalence of cognitive decline and dementia is rising globally, with more than 10 million new cases every year. These conditions cause a significant burden for individuals, their caregivers, and health care systems. As no causal treatment for dementia exists, prevention of cognitive decline is of utmost importance. Notably, alcohol is among the most significant modifiable risk factors for cognitive decline.
Methods
Longitudinal data across 15 years on 6,967 individuals of the Survey of Health, Ageing and Retirement in Europe were used to analyze the effect of alcohol consumption and further modifiable (i.e., smoking, depression, and educational obtainment) and non-modifiable risk factors (sex and age) on cognitive functioning (i.e., memory and verbal fluency). For this, a generalized estimating equation linear model was estimated for every cognitive test domain assessed.
Results
Consistent results were revealed in all three regression models: A nonlinear association between alcohol consumption and cognitive decline was found—moderate alcohol intake was associated with overall better global cognitive function than low or elevated alcohol consumption or complete abstinence. Furthermore, female sex and higher educational obtainment were associated with better cognitive function, whereas higher age and depression were associated with a decline in cognitive functioning. No significant association was found for smoking.
Conclusion
Our data indicate that alcohol use is a relevant risk factor for cognitive decline in older adults. Furthermore, evidence-based therapeutic concepts to reduce alcohol consumption exist and should be of primary interest in prevention measures considering the aging European population.
Glycemic control for elderly diabetics is a challenge. Treatment satisfaction reflects this control.
Objectives
To determine the factors associated with insulin treatment satisfaction among type 2 diabetic elderly.
Methods
A cross-sectional study on 86 type 2 diabetic insulin dependent elderly recruited from the outpatient endocrinology consultation during June and July 2021. We applied the Diabetes Treatment Satisfaction Questionnaire (DTSQ) and geriatric assessment scores.
Results
Three quarters of the patients were satisfied with the insulin therapy. Satisfied patients had significantly less history of hospitalization and more regular follow-up. Diabetic neuropathy medications were significantly less taken by satisfied patients. The number of daily insulin injections was significantly higher in the unsatisfied patients. Diabetic foot was significantly more frequent in unsatisfied patients. Satisfied patients were significantly less depressed, more independent in both basic and instrumental activities of daily living, without memory impairment, in better nutritional status and not falling. Higher DTSQ scores were associated with regular follow up (β 7.92, 95% CI 1.83 to 34.3). Lower DTSQ scores were associated with the history of hospitalization (β 0.12, 95% CI 0.02 to 0.58), the taking of medications for diabetic neuropathy (β 0.07, 95% CI 0.09 to 0.51), the high number of insulin injections (β 0.43, 95% CI 0.19 to 0.97) and the presence of diabetic foot (β 0.17, 95% CI 0.01 to 0.38).
Conclusions
Risk factors for patients’ insulin dissatisfaction should be detected early and managed appropriately to improve patients’satisfaction and consequently their well-being.
Although depression is one of the most common diseases among older people, it is still underdiagnosed due to frequent misleading symptoms.
Objectives
The aims of our study were to assess depression in type 2 diabetic insulin-dependent older adults and to identify factors associated with depression among this population.
Methods
A cross-sectional study on 100 type 2 diabetic insulin-dependent elderly recruited from the outpatient endocrinology consultation during June and July 2021. We applied the geriatric assessment scores: the Geriatric Depression Scale 15-item, the KATS score, the Lawton scale. the five-word test, the Mini Nutritional Assessment and the Timed Up and Go test.
Results
The mean age of the population was 70.8±5.8 years with sex ratio of 0.85. Depression was noted among 57% of the patients who were distributed as follow: around one fifth (21%) had mild depression while 36% had moderate to severe depression. Around one quarter of the patients (24%) were dependent in the basic activities of daily living. Depression was significantly associated with dependency (β = 5.27; 95% CI, 1.01 to 27.35), ophthalmologic diseases (β = 8.81; 95% CI, 2.18 to 35.63), high frequency of nocturia (β = 3.71; 95% CI, 1.24 to 11.05) and high frequency of bleeding at insulin injection site (β = 4.21; 95% CI, 1.49 to 11.84).
Conclusions
Our findings suggest that the prevalence of depression is high among type 2 diabetic insulin-dependent older adults. Early assessment of depression’s risk factors is a major pillar of the comprehensive care of our seniors.
Aging leads to progressive deterioration of physiological function and predisposes to pathological processes. Common geriatric syndromes (such as depression, dementia, falls, mobility impairment, delirium, and osteoporosis), along with age-related impairment in appetite, absorption, and food intake, affect nutrition, symptom presentation, and response to therapy of common gastrointestinal (GI) disorders in the elderly. Age-associated changes in drug metabolism and polypharmacy can result in potential interactions and side effects of drugs used in the treatment of GI diseases, which in turn complicates their management. Polypharmacy, which is common in the elderly, can also exacerbate digestive symptoms. Elderly patients with neurocognitive decline often have atypical presentation of their GI disorders. These factors can make the diagnosis of GI diseases in the elderly more challenging, as they may require different management approaches. In this chapter, we discuss the common GI disorders that affect the elderly with special focus on age-related pathophysiology and clinical implications.
Common urological conditions in older adults include hematuria, urinary tract infections, urological malignancies, and conditions that affect male and female genitalia. The incidence and prevalence of most urological conditions increase with advancing age in both men and women, and approximately 20% of all primary care visits include some type of urological complaint. These conditions can cause significant discomfort and pain, affect quality of life, and some conditions potentially lead to hospitalization and death. Prompt evaluation and treatment are required for effective management.
In the absence of a simple validated instrument to screen for cognitive impairment among illiterate Lebanese older adults, the aims of this study were to validate an Arabic version of the Test of Nine Images (A-TNI93) adapted by the Working Group on Dementia at Saint Joseph University: Groupe de Travail sur les Démences de l’Univesité Saint Joseph (GTD-USJ) for illiterate older Lebanese and to establish normative data.
Method:
A national population-based sample of 332 community-dwelling illiterate Lebanese aged 55 years and older was administered the A-TNI93 (GTD-USJ) scoring free and overall recall. The sample is part of a larger national sample (1342 participants) used to validate an Arabic version of the Mini-Mental State Examination already reported. Reproducibility, sensitivity, specificity, and area under the curve of the A-TNI93 (GTD-USJ) scoring to detect cognitive impairment according to Clinical Dementia Rating (CDR) as the gold standard were measured. Normative data were established among 188 cognitively normal participants.
Results:
A threshold score of six on free recall (FR) provided a sensitivity of 66.7% and a specificity of 90.5%. The area under the curve was 0.93. By taking either scores, that is, a FR ≤ 6 or a total recall ≤ 8, the A-TNI93 (GTD-USJ) slightly improved dementia case detection with a sensitivity of 70.8% and a specificity of 88%. Normative data illustrate the distribution of cognitive performance among illiterate older adults.
Conclusions:
Compared to the CDR requiring physician’s competence, the A-TNI93 (GTD-USJ) is a valid Arabic adaptation to screen for cognitive impairment among illiterate Lebanese older adults.
Transition care programmes (TCP) provide older adults with goal-oriented rehabilitation after hospitalisation. However, limited research has focused on understanding older adults' experiences when undertaking TCP. Using a phenomenological approach, we explored the lived experience of older adults undertaking a TCP at a transition care facility in Australia. A purposive sample (N = 33 participants: 16 older adults, four family members and 13 staff) was recruited. Semi-structured interviews were undertaken at three time-points during admission and inductive thematic analysis was utilised. Older adults reflected on their TCP experiences through an emotional lens through which they deliberated, ‘is my destination home?’ Fear of losing independence and uncertainty about their discharge destination strongly influenced older adults' perspectives regarding their TCP experience. Emotional responses, both positive and negative, were influenced by expectations prior to admission, level of family support and staff behaviour. Staff and family concurred that many older adults were confused about their admission to the facility and initially were unprepared to engage in the rehabilitation provided. Older adults experienced TCP as a time of great uncertainty and feared the unknown when discharged from hospital to transition care. They expressed grief at the loss of existing life roles and anxiety about the possibility of being unable to return home. Health professionals need to inform and tailor rehabilitation for older adults to better support this transient time of life.
The aim is to understand the experiences and views of oncology nurses about the unmet care needs of older cancer patients receiving chemotherapy. Nurses play the key role in evaluating and determining the needs of this special group.
Method
A phenomenological descriptive qualitative study with convenience sampling was used. Participants were referred by the Turkish Oncology Nursing Society. The study participants were 12 nurses aged 34–53 years, with oncology experience between 5 and 27 years. The data were collected using semi-structured face-to-face interviews. Interviews were transcribed verbatim with concurrent analyses and data collection. Thematic content analysis was used to determine common domains.
Results
The study data were categorized into 3 contexts, 12 themes, and 37 subthemes. The first context, “unmet needs”, includes physical care, psychological care, and social care themes. The second context, “barriers to meeting those needs”, comprises the theme of patient characteristics, attitude of family, attitude of the nurses/healthcare team, health system, and culture. The last context is “suggestions for meeting needs”. Nurses play an important role in identifying and meeting unmet psychosocial needs.
Significance of results
The study indicated that older cancer patients had problems in identifying, expressing, and making demands for their needs and that their culture contributed to this situation. Nurses serving in the outpatient chemotherapy units should conduct a holistic assessment of older cancer patients, be aware that these patients may not be able to express their needs, be more sensitive toward them, and ensure that the voice of the older patients is heard.
Acute facial palsy is a consequence of various diseases, with the number of patients increasing with advancing age. This study aimed to analyse the clinical characteristics of acute peripheral facial palsy in older adults.
Methods
A total of 30 patients with a mean age of 68.4 ± 9.1 years were included in the study. All patients received a standardised investigation and follow up. The hospital charts of the patients with acute facial palsy were reviewed retrospectively.
Results
The predominant causes of acute facial palsy in older adults were: Bell's palsy, Ramsay Hunt syndrome, trauma, otitis media and malignancy. At baseline, complete and incomplete facial palsies were seen in 26.7 per cent and 73.3 per cent of patients, respectively. The overall rates of good recovery, partial recovery and no recovery were 66.7 per cent, 10 per cent and 23.3 per cent, respectively. Increased age led to a significantly lower level of recovery in older adults.
Conclusion
Bell's palsy and Ramsay Hunt syndrome were the most common aetiologies of acute facial palsy in older adults, and such patients are likely to have incomplete recovery. Active early treatment is necessary for achieving good outcomes in older adults.
To investigate the relationship of a healthy eating score with depression in Chilean older adults.
Design:
Cross-sectional study.
Setting:
Older adults from the Chilean National Health Survey 2016–2017. Associations were analysed using complex samples multivariable logistic regressions adjusted for age, sex, socio-demographic, lifestyles (physical activity, smoking, alcohol consumption and sleep duration), BMI and clinical conditions (hypertension, diabetes, hypercholesterolaemia and cardiovascular diseases).
Participants:
The number of participants was 2031 (≥ 60 years). The Composite International Diagnostic Interview-Short Form was applied to establish the diagnosis of major depressive episode. Six healthy eating habits were considered to produce the healthy eating score (range: 0–12): consumption of seafood, whole grain, dairy, fruits, vegetables and legumes. Participants were categorised according to their final scores as healthy (≥ 9), average (5–8) and unhealthy (≤ 4).
Results:
Participants with a healthy score had a higher educational level, physical activity and regular sleep hours than participants with an average and unhealthiest healthy eating score. Participants classified in the healthiest healthy eating score had an inverse association with depression (OR: 0·28, (95 % CI 0·10, 0·74)). Food items that contributed the most to this association were legumes (15·2 %) and seafood (12·7 %).
Conclusion:
Older adults classified in the healthiest healthy eating score, characterised by a high consumption of legumes and seafood, showed a lower risk for depression in a representative sample of Chilean population.
Computerised neuropsychological assessments (CNAs) are proposed as an alternative method of assessing cognition to traditional pencil-and-paper assessment (PnPA), which are considered the “gold standard” for diagnosing dementia. However, limited research has been conducted with culturally and linguistically diverse (CALD) individuals. This study investigated the suitability of PnPAs and CNAs for measuring cognitive performance in a heterogenous sample of older, Australian CALD English-speakers compared to a native English-speaking background (ESB) sample.
Methods:
Participants were 1037 community-dwelling individuals aged 70–90 years without a dementia diagnosis from the Sydney Memory and Ageing Study (873 ESB, 164 CALD). Differences in the level and pattern of cognitive performance in the CALD group were compared to the ESB group on a newly developed CNA and a comprehensive PnPA in English, controlling for covariates. Multiple hierarchical regression was used to identify the extent to which linguistic and acculturation variables explained performance variance.
Results:
CALD participants’ performance was consistently poorer than ESB participants on both PnPA and CNA, and more so on PnPA than CNA, controlling for socio-demographic and health factors. Linguistic and acculturation variables together explained approximately 20% and 25% of CALD performance on PnPA and CNA respectively, above demographics and self-reported computer use.
Conclusions:
Performances of CALD and ESB groups differed more on PnPAs than CNAs, but caution is needed in concluding that CNAs are more culturally-appropriate for assessing cognitive decline in older CALD individuals. Our findings extend current literature by confirming the influence of linguistic and acculturation variables on cognitive assessment outcomes for older CALD Australians.
A palliative approach to care aims to meet the needs of patients and caregivers throughout a chronic disease trajectory and can be delivered by non-palliative specialists. There is an important gap in understanding the perspectives and experiences of primary care providers on an integrated palliative approach in dementia care and the impact of existing programs and models to this end. To address these, we undertook a scoping review. We searched five databases; and used descriptive numerical summary and narrative synthesizing approaches for data analysis. We found that: (1) difficulty with prognostication and a lack of interdisciplinary and intersectoral collaboration are obstacles to using a palliative approach in primary care; and (2) a palliative approach results in statistically and clinically significant impacts on community-dwelling individuals, specifically those with later stages of dementia. There is a need for high-quality research studies examining the integrated palliative approach models and initiation of these models sooner in the care trajectory for persons living with mild and moderate stages of dementia in the community.
