ABSTRACT

BACKGROUND/OBJECTIVES: Slow gait speed prospectively predicts elevated risk of adverse events such as falls, morbidity, and mortality. Additionally, gait speed under a cognitively demanding challenge (dual-task gait) predicts further cognitive decline and dementia incidence. This evidence has been mostly collected using electronic walkways; however, not all clinical set ups have an electronic walkway and comparability with simple manual dual-gait speed testing, like a stopwatch, has not yet been examined. Our main objective was to assess concurrent-validity and reliability of gait speed assessments during dual-tasking using a stopwatch and electronic walkway in older adults with mild and subjective cognitive impairment (MCI and SCI). DESIGN: Cross-sectional, reliability study. SETTING: Clinic based laboratory at an academic hospital in London, ON, Canada. PARTICIPANTS: 237 walk tests from 34 community-dwelling participants (mean age 71.84 SD 5.38; 21 female - 62%, 13 male - 38%) with SCI and MCI. were included from the Comprehensive Assessment of Neurodegeneration and Dementia (COMPASS-ND) study. INTERVENTION: Each participant performed seven walk tests: three single gait walks at their normal pace, three dual-task walks (walking and counting backwards by one, by sevens, and naming animals), and one fast walk. MEASUREMENTS: Gait speed (cm/s) for each walk was measured simultaneously with an electronic walkway (Zeno Mat®) and a handheld stopwatch (Ultrak chronometer®). Dual-task cost (DTC) was calculated for the three individual dual-task walks as [((single gait speed - dual-task gait speed) / single gait speed) ∗ 100]. Level of agreement between the two measurement methods was analyzed using Pearson correlations, paired t-tests, and Bland-Altman plots. RESULTS: Gait speed was consistently lower when measured with the stopwatch than with the electronic walkway (mean speed difference: 10.6 cm/s ± 5.1, p < 0.001). Calculating DTC, however, yielded very similar results with both methods (mean DTC difference: 0.19 ± 1.18, p = 0.872). The higher the DTC, the closer the measurement between methods. CONCLUSION: Assessing and calculating DTC with a stopwatch is simple, accessible and reliable. Its validity and reliability were high in this clinical sample of community older adults with SCI and MCI.

ABSTRACT

BACKGROUND: Currently there are no disease-modifying treatments for Parkinson's disease dementia (PDD), a condition linked to aggregation of the protein α-synuclein in subcortical and cortical brain areas. One of the leading genetic risk factors for Parkinson's disease is being a carrier in the gene for ß-Glucocerebrosidase (GCase; gene name GBA1). Studies in cell culture and animal models have shown that raising the levels of GCase can decrease levels of α-synuclein. Ambroxol is a pharmacological chaperone for GCase and is able to raise the levels of GCase and could therefore be a disease-modifying treatment for PDD. The aims of this trial are to determine if Ambroxol is safe and well-tolerated by individuals with PDD and if Ambroxol affects cognitive, biochemical, and neuroimaging measures. METHODS: This is a phase II, single-centre, double-blind, randomized placebo-controlled trial involving 75 individuals with mild to moderate PDD. Participants will be randomized into Ambroxol high-dose (1050 mg/day), low-dose (525 mg/day), or placebo treatment arms. Assessments will be undertaken at baseline, 6-months, and 12-months follow up times. Primary outcome measures will be the Alzheimer's disease Assessment Scale-cognitive subscale (ADAS-Cog) and the ADCS Clinician's Global Impression of Change (CGIC). Secondary measures will include the Parkinson's disease Cognitive Rating Scale, Clinical Dementia Rating, Trail Making Test, Stroop Test, Unified Parkinson's disease Rating Scale, Purdue Pegboard, Timed Up and Go, and gait kinematics. Markers of neurodegeneration will include MRI and CSF measures. Pharmacokinetics and pharmacodynamics of Ambroxol will be examined through plasma levels during dose titration phase and evaluation of GCase activity in lymphocytes. DISCUSSION: If found effective and safe, Ambroxol will be one of the first disease-modifying treatments for PDD. TRIAL REGISTRATION: ClinicalTrials.gov NCT02914366, 26 Sep 2016/retrospectively registered.

ABSTRACT

BACKGROUND AND PURPOSE: Cognitive enhancers are commonly prescribed to people with Alzheimer's disease and related dementias to improve cognition and function. However, their effectiveness for individuals in the pre-stages of dementia, particularly in functional motor outcomes, remains unknown. We aimed to determine the efficacy of donepezil, a cognitive enhancer that improves cholinergic neurotransmission, on gait performance in mild cognitive impairment (MCI). METHODS: This was a double-blind, placebo-controlled trial including 60 older adults with MCI, randomized to receive donepezil (10 mg/daily, maximal dose) or placebo. Primary outcome was gait speed (cm/s) under single and three dual-task conditions (counting backwards by 1 or 7 and naming animals) measured using an electronic walkway. Dual-task gait cost (DTC), a valid measure of motor-cognitive interaction, was calculated as the percentage change between single (S) and dual-task (D) gait speeds: [(S - D)/S] × 100. Secondary outcomes included attention, executive function, balance and falls. RESULTS: After 6 months, the donepezil group experienced an improvement in dual-task gait speed (range 4-11 cm/s), although this was not statistically significant. The donepezil group showed a significant reduction in DTC (improvement) by counting backwards by 1 and 7 compared with placebo (10.25% vs. 1.75%, P = 0.048; 21.38% vs. 14.64%, P = 0.037, intention-to-treat analysis). Per-protocol analyses showed that all three DTCs improved in the donepezil group, along with a non-significant reduction of rate of falls. CONCLUSIONS: Donepezil treatment improved dual-task gait speed and DTC in elderly patients with MCI. Our results support the concept of reducing falls in MCI by targeting the motor-cognitive interface.

ABSTRACT

Altered neurometabolic profiles have been detected in Alzheimer disease (AD) using (1)H magnetic resonance spectroscopy (MRS), but no definitive biomarker of mild cognitive impairment (MCI) or AD has been established. This study used MRS to compare hippocampal metabolite levels between normal elderly controls (NEC) and subjects with MCI and AD. Short echo-time (TE=46 ms) (1)H spectra were acquired at 4T from the right hippocampus of 23 subjects with AD, 12 subjects with MCI and 15 NEC. Absolute metabolite levels and metabolite ratios were compared between groups using a multivariate analysis of covariance (covariates: age, sex) followed by post hoc Tukey's test (p<0.05 significant). Subjects with AD had decreased glutamate (Glu) as well as decreased Glu/creatine (Cr), Glu/myo-inositol (mI), Glu/N-acetylaspartate (NAA), and NAA/Cr ratios compared to NEC. Subjects with AD also had decreased Glu/mI ratio compared to MCI. There were no differences between subjects with MCI and NEC. Therefore, in addition to NAA/Cr, decreased hippocampal Glu may be an indicator of AD.

ABSTRACT

OBJECTIVE: This report describes the pilot testing of an educational intervention to manage acute pain associated with wound care in an outpatient clinic. The intervention included essential elements of pain education identified in the acute pain literature: provision of information; pain measurement; establishing expectations; treatment planning; teaching environment. METHOD: The intervention was tested on five patients attending a wound clinic for scheduled treatment. Patients were aged 65 years or older and had a history of experiencing pain during treatment procedures such as dressing changes and debridement. Before the intervention, the study nurse gave the patients information about the procedure, discussed strategies they could use to make it as comfortable as possible, and explained how they could use a rating scale to denote any physical and emotional distress. RESULTS: All patients used the intervention strategies. Three out of five reported reduced pain and/or distress following the intervention. CONCLUSION: The pilot study supported the use of education as a pain control strategy in wound care and illuminated key methodological issues for further research on this topic.

ABSTRACT

The purpose of this study was to identify risk factors for urinary retention (UR) in frail, elderly patients, to determine its prevalence, and to assess the validity of the use of the BladderScan BVI 2500+ ultrasound scanner to measure postvoid residual urine volumes of > or = 150 ml. Probable UR was defined as two consecutive ultrasound scans with postvoid residual urine estimations of > or = 150 ml. The estimates were confirmed by in- and out-catheterization of actual postvoid residual urine (PVR). Risk factors for UR were the independent variables used in the regression analysis. Nineteen of the 167 people (11%) had UR. The risk of UR was greatest among patients who were older, or who were on anticholinergic medication, or who had diabetes of long standing, or who had fecal impaction. The correlation between paired scans and catheter volumes of > or = 150 ml was 0.87. The results suggest that the BladderScan BVI 2500+ ultrasound scanner, when used by trained nursing staff, provides conservative and valid estimates of PVR of > or = 150 ml in people undergoing geriatric rehabilitation.

ABSTRACT

OBJECTIVES: To determine the relative independent contributions of mobility and mental function to the prevalence rate of incontinence in a long-term care hospital and to establish the baseline prevalence rate and cost of incontinence before implementation of a continence program. DESIGN: Prevalence survey. SETTING: Long-term care hospital. PARTICIPANTS: All 457 inpatients (mean age of men 73.6 years, of women 73.8 years) who met the defined criteria for degree of urinary and fecal incontinence, mobility and mental function. Of the 447 questionnaires that were returned 12 were incomplete. MAIN OUTCOME MEASURES: Degree of urinary and fecal incontinence and costs of incontinence as measured by nursing time spent dealing with incontinent patients, laundry and incontinence supplies. RESULTS: The prevalence rate of urinary incontinence was 62%, fecal incontinence 46% and combined incontinence 44%. The mean time spent each day dealing with incontinence was 52.5 minutes per patient. The total annual cost of incontinence per patient was $9771. Mobility and mental function were independent predictors of frequency of urinary and fecal incontinence. Frequency of incontinent events was the strongest predictor of quantity of linen soiled, but immobility was the strongest predictor of nursing time spent dealing with incontinence. CONCLUSIONS: The prevalence rate of urinary incontinence depends on patient characteristics and the definition of incontinence. A management approach to incontinence could lower laundry and supply costs, and improvements in mobility could reduce nursing time spent dealing with incontinence.

ABSTRACT

The relationship between behavioral symptoms and cognitive impairment in Alzheimer's Disease (AD) is only poorly understood. The aim of the present study was to examine cognitive correlates of urinary incontinence in AD. Although incontinence is generally accepted as an accompaniment of AD, it was our clinical impression that it correlated poorly with global measures of cognitive impairment. A retrospective pilot study of 17 incontinent demented patients and 17 continent patients, matched for age, sex, and total score on the Folstein Mini-Mental Status Exam (MMSE), revealed a striking association between an inability to do a copy task and urinary incontinence. A prospective study confirmed this finding in a sample of 45 patients meeting DSMIII-R diagnostic criteria for dementia, probable Alzheimer's disease. The 17 incontinent patients did not differ from the 28 continent patients in age, sex distribution, or total score on the MMSE. However, the incontinent subjects scored significantly lower on a cube copying task. Qualitative analysis revealed that the drawings by incontinent patients showed features comparable with those observed in the drawings by patients with right-sided parietal lesions, in particular, poor representation of perspective and spatial orientation. Further investigation of the relationship between copying performance and incontinence may have implications for understanding the cortical mechanisms of urinary continence. The present results also underscore the limitations of the MMSE as a measure of dementia severity and suggest there are areas of cognitive ability which are inadequately assessed by MMSE but which may be of major important in understanding the loss of functional skills in the dementing patient.

ABSTRACT

A sample of 761 subjects 70 years and over was drawn from general-practice records of a rural township. Each subject was assessed and followed for 1 year to determine the incidence of and factors related to falls. The fall rate (number of falls per 100 person-years) increased from 47 for those aged 70-74 years to 121 for those 80 years and over. There was no sex difference in fall rate but men were more likely than women to fall outside and at greater levels of activity. Twenty per cent of falls were associated with trips and slips but we found no evidence that inspection of homes and installation of safety features would have decreased the fall rate. Ten per cent of falls resulted in significant injury. Men who fell had an increased subsequent risk of death compared with those who did not fall (relative risk 3.2, 95% CI 1.7-6.0). Subsequent mortality was increased among women who fell but not to significant levels (relative risk 1.6, 95% CI 0.9-2.7).

ABSTRACT

Corrected arm muscle area (CAMA), triceps skin-fold thickness (TSF) and body mass index (BMI) were measured in a community sample of 758 people who were then followed for 40-46 months. Percentile values were calculated for each sex in 5-year age groups. The relative risk of death of those in the upper and lower percentiles was compared with those between the 10th and 90th percentiles, controlling for age and sex. Subjects below the 5th percentile for CAMA, TSF and BMI and between the 5th and 10th percentile for CAMA had a significantly increased risk of death. There was no increased risk of death in those subjects above the 90th percentile in any measurement. In the logistic regression model, both low CAMA and low TSF were associated with a significantly increased risk of subsequent mortality. Poor nutritional state shown by low muscle bulk and fat stores was an important predictor of mortality, but obesity had no adverse effect on survival.

ABSTRACT

In a community based, prospective study to determine risk factors for falls, 465 women and 296 men 70 years and over were followed for 1 year and 507 falls were documented. A greater proportion of women (32.7%) than men (23.0%) experienced at least one fall in which there was no or minimal external contribution. Using unconditional logistic regression models we investigated the effect of physical and sociological variables on the sex difference in fall rate. Controlling for the variables age, use of psychotropic drugs, inability to rise from a chair without using arms, going outdoors less than daily and living alone decreased the relative risk of women falling compared to men from 2.02 (95% CI, 1.40-2.92) to 1.55 (95% CI 1.04-2.31). Some of the increased risk of falling associated with being a women was able to be explained and is potentially correctable. But even after controlling for the physical and social variables which we had assessed, women compared to men still had a significantly increased relative risk of falling.

ABSTRACT

We investigated factors associated with falls in a community-based prospective study of 761 subjects 70 years and older. The group experienced 507 falls during the year of monitoring. On entry to the study a number of variables had been assessed in each subject. Variables associated with an increased risk of falling differed in men and women. In men, decreased levels of physical activity, stroke, arthritis of the knees, impairment of gait, and increased body sway were associated with an increased risk of falls. In women, the total number of drugs, psychotropic drugs and drugs liable to cause postural hypotension, standing systolic blood pressure of less than 110 mmHg, and evidence of muscle weakness were also associated with an increased risk of falling. Most falls in elderly people are associated with multiple risk factors, many of which are potentially remediable. The possible implications of this in diagnosis and prevention are discussed.

ABSTRACT

A 79-year-old woman was admitted to hospital complaining of chest pain, increasing weakness, anorexia, hoarseness, headache and discomfort in the throat and jaws while eating. Physical examination, chest x-rays, serial electrocardiograms and cardiac enzymes were unremarkable. After admission she developed weakness and numbness in the left leg with urinary retention, decreased sensation to touch, weakness, increased tone, absent deep tendon reflexes and a positive Babinski sign on the left. Zeta sedimentation rate was markedly elevated at 0.63. Computerized tomographic head scan, myelography, echocardiography, barium swallow and meal, immunoglobulins, electrophoresis and other laboratory investigations were unremarkable. Repeat sedimentation rate was still markedly elevated three weeks later. A temporal artery biopsy confirmed the diagnosis of temporal or giant cell arteritis. Prednisone, 60 mg daily, was started.

ABSTRACT

The usual alcohol intake in a community-based sample of subjects aged 70 years and over was investigated. A sample of 825 subjects was drawn from the records of five general practices in a rural township and 774 subjects (93.8%) agreed to participate. A stratified sub-sample of subjects from the abstainers, infrequent, weekly, and daily drinkers was subsequently investigated in more detail. Men took alcohol more frequently than women and in greater quantities although frequency and amount decreased with age. The usual place for drinking was the home. The highest use of psychotropic drugs occurred in the abstainers, but this was significant for men only. When compared with drinking patterns in middle age, 60.1% of men and 30.3% of women said that they took less alcohol, while 7.4% of men and 11.1% of women said that they took more. The main reasons for decrease in alcohol intake were change in health and fewer social opportunities. The main reasons for increase in alcohol intake were more money and more time. Drinking was most commonly associated with social activities and few took alcohol to help cope with personal situations.

ABSTRACT

Fit elderly score higher on tests of fluid intelligence than aged-matched sedentary controls. Elderly patients who have taken part in exercise programs have shown improvement in mental function. We compared the effects of 45 minutes of exercise on memory, mood, and cognitive function in elderly subjects to a control intervention using a randomized control study design. Neuropsychological tests employed where the color slide test, digit symbol test, digit span test, logical memory test, word fluency test, and the Mini-Mental State Examination. We measured mood using a mood test and geriatric depression scale. Each subject was tested before, and immediately after, control and exercise sessions. Fifteen elderly subjects [ten men and five women; mean age, 66 years, (range, 60 to 85 years)] completed the study. There was a greater improvement in six of the eight scores of cognitive function following exercise, compared to control. These differences were significantly greater following exercise for the logical memory test score (P less than or equal to 0.02) and Mini-Mental State Examination (P less than or equal to 0.025) compared with the control intervention.

ABSTRACT

In a prospective study of falls in 761 subjects 70 years and over an increase in the rate of falls in winter was observed in women but not men. When the daily minimum temperature fell to 1 degrees C or less the relative risk of falling in women increased to 1.53 (95% confidence intervals 1.21-1.84). We discuss measures to decrease this seasonal increase in the rate of falls.

ABSTRACT

During one year 151 patients with 154 strokes were studied prospectively to determine the occurrence and outcome of urinary incontinence after a stroke. Seventeen per cent had pre-existing urinary incontinence. At 1, 4 and 12 weeks, 60%, 42% and 29% of the survivors, respectively, were not continent. Cystometry was performed in those with moderate or severe urinary incontinence persisting 4 weeks after the stroke. Detrusor instability was present in 85% of those who had been continent prior to their stroke. Factors associated with urinary incontinence at 4 weeks were moderate or severe motor deficit, impaired mobility and mental impairment (P less than 0.001). Two-thirds of patients with mild urinary incontinence at 4 weeks regained continence by 12 weeks.

ABSTRACT

Osteomalacia in New Zealand and Australia has previously been thought rare. The medical records of 22 elderly inpatients diagnosed as having osteomalacia on biopsy criteria in Dunedin between January 1980 and December 1983 were reviewed. Risk factors, mode of presentation, month of presentation, biochemistry, bone biopsy, bright line counting and bone scans were assessed. Our findings, and a review of the diagnosis of osteomalacia in the elderly are discussed. We conclude that in the elderly, osteomalacia is not uncommon, and recommend increased attention to risk factors and biochemical screening.
