Objective: Apathy is a common behavioral problem in Alzheimer’s disease. has profound consequences, such as functional impairment, higher service utilization, caregiver burden, and increased mortality. The authors’ objective was to study the effects of methylphenidate on apathy Method: A 12-week, prospective, double-blind, randomized, placebo-controlled trial (methylphenidate versus placebo) conducted community-dwelling veterans (N=60) with mild primary outcome for (Apathy Evaluation...
<h3>Importance</h3> Suicide and suicide attempts are persistent increasing public health problems. Observational studies meta-analyses of randomized clinical trials have suggested that lithium may prevent in patients with bipolar disorder or depression. <h3>Objective</h3> To assess whether augmentation usual care reduces the rate repeated episodes suicide-related events (repeated attempts, interrupted hospitalizations to suicide, deaths from suicide) participants depression who survived a...
<h3>Background</h3> The efficacy of ad libitum low-fat diets in reducing body weight and fat overweight obese adults remains controversial. <h3>Methods</h3> We examined the effect a 12-week low-fat, high–complex carbohydrate diet alone (HI-CHO) combination with aerobic exercise training (HI-CHO + EX) on composition 34 individuals impaired glucose tolerance (20 women 14 men; mean ± SEM age, 66 1 years). Participants were randomly assigned to control (41% fat, 14% protein, 45% carbohydrates, 7...
Megestrol acetate (MA) (Bristol-Myers Squibb Co., Princeton, NJ) increases weight gain in AIDS and cancer patients age-related cachexia; however, the is predominately fat. We determined if adding resistance exercise and/or testosterone (T) replacement to MA administration would result a more favorable body composition change than alone. Thirty older men (aged 67.0 ± 5.8) completed this 12-wk study. All subjects received were randomly assigned one of following groups: placebo (P) injections,...
Although data suggest that physical activity is associated with decreased insulin resistance, recommendations for exercise training are not specific age or level of obesity. Therefore, we examined the influence moderate-intensity (50% VO2max) (MI) versus high-intensity (75% (HI) on insulin-stimulated glucose disposal (ISGD) in elderly individuals.Following medical examinations, 21 overweight (body mass index = 29 +/- 1 kg x m(-2)) (74 yr) subjects were randomized to 1) HI, 2) MI, a 3)...
Background. Although weight change in older persons has proven prognostic significance, it is not known whether monthly weights obtained by the clinical staff long-term care institutions are reliable enough to be useful identifying at-risk residents. The objective of this study was determine an association exists between mortality risk and intraresident variation institutions. Methods. For study, 900 nursing home residents with a recently identified nutritional problem from 96 facilities 8...
AbstractThe primary objective of this cross-sectional study was to test the hypothesis that plasma concentration insulin-like growth factor I (IGF-I) correlates with risk in-hospital morbidity among metabolically stable elderly. The secondary determine whether IGF-I other putative indicators protein-energy nutritional status.To meet these objectives, 110 randomly selected admissions a Geriatric Rehabilitation Unit (GRU) Veterans Administration hospital were studied. average age patients 76...
Background. The objective of this study was to examine the relationship between serum IGF-I concentration and incidence side effects therapy with recombinant human growth hormone (rhGH) insulin-like factor-I (rhIGF-I). Methods. Thirteen high-risk, undernourished elderly males were started on a 15-day course rhGH rhIGF-I by subcutaneous injection. dose held constant at .0125 mg/kg/day, whereas increased in stepwise fashion from 10μg/kg targeted 40 μg/kg twice day. Results. Nine subjects...
Although anthropometrics have traditionally been utilized in the assessment of protein‐energy malnutrition, little is known reliability these measurements elderly patient populations. In this study, an anthropometric measurement protocol, designed for ease both independent and functionally debilitated patients, evaluated. An analysis variance technique was used to calculate test‐retest each three observers. experience observers equivalent, precision their varied considerably. After repeat...
To determine the incidence, prevalence, and duration of urinary incontinence, a survey was undertaken all patients aged 65 over admitted to university hospital during six‐week period. The daily prevalence which 19 per cent for entire study population, highly variable from one nursing unit another. Twenty‐five those on acute care general medical units 17 surgical were incontinent any given day. burn had highest incontinence (75 cent). incidence stay, determined 315 who followed admission...
Background. Previous studies have demonstrated that aerobic exercise training and weight loss independent effects on insulin-stimulated glucose disposal (ISGD). We hypothesized ad libitum consumption of a high-carbohydrate diet would result in improved ISGD, facilitate greater improvements ISGD compared with alone. Methods. Older participants (13 women, 9 men; age = 66 ± 1 year) impaired tolerance were randomly assigned to an alone (18% fat, 19% protein, 63% carbohydrate) or this plus (4...
African American women have a high prevalence of obesity, which partially may be explained by their lower rates resting energy expenditure (REE). The aim this study was to examine the influence acute sibutramine administration on REE and post-exercise in women.
Background. Previous studies have identified relationships between subcutaneous abdominal fat (SAF), visceral (VF), and insulin resistance. In addition, lower muscle attenuation decreased adiponectin also been associated with
1 The aim of the present study was to examine associations between micronutrients, inflammation and prevalence congestive heart failure (CHF) in elderly aged 65 years, using US National Health Nutrition Examination Surveys. 2 After adjusting for age, gender, race/ethnicity other covariates, subjects with decreased folate vitamin B12 intake elevated serum levels inflammatory biomarkers (C-reactive protein total homocysteine) had significantly higher risk CHF than their counterparts. 3 Elderly...
OBJECTIVE : To investigate whether the physiological response to surgery‐induced stress, as measured by changes in serum secretory proteins, is more profound older than younger total joint arthroplasty patients. DESIGN Retrospective study. SETTING A 267‐bed teaching hospital. PARTICIPANTS of 220 ambulatory patients with normal admission albumin levels, whom 106 were 65 years age or (mean 73.3 ± 6.2 years) and 114 less 48.8 12.2 years). METHODS Serum transferrin levels obtained at on fifth...
Our work identifies subjects based on their height and the distance between joints. Using a depth sensing camera, we obtained position of person's joints in 3D space relative to each other. The distances adjacent subject's head are used create vector eight features for an individual use identification. modified KNN, full partial feature sets were identify subjects. Additionally, our classifier can be utilized assess ambulation (such as walking's velocity distance) subject, when identified.
