Multidimensional patterns of aging in 70-year-olds: survival differences.

This article examines the predictive ability for survival of five multidimensional patterns of aging found in 335 70-year-olds from the geriatric and gerontological studies in Gothenburg, Sweden (H-70). The multidimensional patterns were identified by cluster analysis of the domains of cognitive performance, physical health, functional capacity, subjective well-being, and social contacts. Survival differences are found among the patterns and between genders within the patterns. Patterns with higher domain scores at age 70 have higher median survival rates over 20 years. Conversely, patterns with lower domain scores at age 70 have earlier mortality. However, one group, with the lowest cognitive score, has a survival pattern similar to the group with low scores in every domain, substantiating the finding that poor cognitive performance is an important single predictor of mortality. Females exhibit at least a 4-year survival advantage over males in all but one group, in which the males resemble the females in their survival.

Chronometric comparisons of imagery to action: visualizing versus physically performing springboard dives.

Motor imagery research emphasizes similarities between the mental imagery of an action and its physical execution. In this study, temporal differences between motor imagery and its physical performance as a function of performer expertise, skill complexity, and spatial ability were investigated. Physical execution times for springboard dives were compared with visualized execution times. Results indicate that physical and visualized performance times were not identical: Their relation is a function of dive complexity and diver expertise, but not their interaction. Relative to physical time, visualization time increased with increased complexity, suggesting the involvement of capacity-limited working memory. A nonmonotonic relation was found for expertise: Unlike experts or novices, visualization time for intermediates was significantly slower than physical time. These temporal differences are most consistent with schematic differences in skill representation. Intermediates may be relatively slowed by greater amounts of nonautomatized knowledge, as compared with the automatized knowledge of experts or the sparse knowledge of novices.

Sustained cardiac diastolic changes elicited by ultrafiltration in patients with moderate congestive heart failure: pathophysiological correlates.

OBJECTIVE: To investigate the pathophysiological (cardiac function and physical performance) significance of clinically silent interstitial lung water accumulation in patients with moderate heart failure; to use isolated ultrafiltration as a means of extravascular fluid reabsorption. DESIGN: Echocardiographic, Doppler, chest x-ray evaluations, and cardiopulmonary tests at baseline, soon after ultrafiltration (veno venous extracorporeal circuit), and four days, one month, and three months later. SETTING: University institute of cardiology. SUBJECTS: 24 patients with heart failure due to idiopathic dilated cardiomyopathy or ischaemic myocardial disease with sinus rhythm and ejection fraction less than 35%. Twelve were randomised to ultrafiltration and 12 were taken as controls. MAIN OUTCOME MEASURES: Left ventricular systolic function (from ultrasonography); Doppler evaluation of mitral, tricuspid, and aortic flow and echo-Doppler determination of cardiac output; radiological score of extravascular lung water; right and left ventricular filling pressures; oxygen consumption at peak exercise and exercise tolerance time in cardiopulmonary tests. RESULTS: Soon after ultrafiltration (1976 (760) ml of fluid removed) the following was observed: a reduction in radiological score of extravascular lung water (from 15(1) to 9(1)) and of right (from 7.1 (2.3) to 2.3 (1.7) mm Hg) and left (from 17.6 (8.8) to 9.5 (6.4) mm Hg) ventricular filling pressures; an increase in oxygen consumption at peak exercise (from 15.8 (3.3) to 17.6 (2) ml/min/kg) and of tolerance time (from 444 (138) to 508 (134) s); a slight decrease in atrial and ventricular dimensions; no changes in the systolic function of the left ventricle; a reduction of the early to late filling ratio in both ventricles (mitral valve from 2 (2) to 1.1 (1.1)); (tricuspid valve from 1.3 (1.3) to 0.69 (0.18)) and an increase in the deceleration time of mitral and tricuspid flow, reflecting a redistribution of filling to late diastole. Variations in the ventricular filling pattern, lung water content, and functional performance persisted for three months in all cases. None of these changes was detected in the control group. CONCLUSIONS: Reduction of interstitial lung water was probably the mechanism whereby ultrafiltration modified the pattern of filling of the two ventricles and improved functional performance.

A randomized trial of physical rehabilitation for very frail nursing home residents.

BACKGROUND: Past studies suggest multidisciplinary interventions that include physical therapy (PT) can improve function of nursing home residents. This trial specifically evaluates effects of PT for frail long-stay nursing home residents. DESIGN: Randomized, controlled trial. SETTING: One academic nursing home and eight community nursing homes. PATIENTS: A total of 194 elderly nursing home residents dependent in at least two activities of daily living residing in the nursing home for at least 3 months. INTERVENTIONS: Patients were randomized to individually tailored one-on-one PT sessions or friendly visits (FVs) three times a week for 4 months. Physical therapy included range-of-motion, strength, balance, transfer, and mobility exercises. MAIN OUTCOME MEASURES: Performance-based physical function assessed by the Physical Disability Index; self-perceived health status assessed with the Sickness Impact Profile; observer-reported activities of daily living; and falls. RESULTS: Eighty-nine percent and 92% of PT and FV sessions, respectively, were attended; 5% and 9% of subjects dropped out in the PT group and FV group, respectively. Compared with the FV group, the PT group experienced no significant improvements in overall Physical Disability Index, Sickness Impact Profile, or activities of daily living scores. A 15.5% improvement in the mobility subscale of the Physical Disability Index was seen (95% confidence interval [CI], 6.4% to 24.7%); no benefits in range-of-motion, strength, or balance subscales were found. Compared with the FV group, the PT group used assistive devices for bed mobility tasks less often (P = .06) and were less likely to use assistive devices and wheelchairs for locomotion (P < .005). There were 79 falls in the PT group vs 60 falls in the FV group (P = .11). Charge for the 4-month PT program was $1220 per subject (95% CI, $412 to $1832). CONCLUSION: This standardized physical therapy program provided modest mobility benefits for very frail long-stay nursing home residents with physical disability due to multiple comorbid conditions.

Lung function and treadmill performance of smoking and nonsmoking males receiving ascorbic acid supplements.

Twelve cigarette smoking and 10 nonsmoking healthy human volunteers, 25 to 38 yr of age, performed lung function and treadmill performance tests over two periods of 3 wk duration while taking either ascorbic acid (300 mg daily) or placebo tablets in a cross-over design. The two exercise periods were separated by a one-month inactive phase. Tablets were administered in a random, double-blind manner. Plasma vitamin C levels were significantly increased after 3 wk of ascorbic acid supplementation in both smokers and nonsmokers as compared to initial levels in the same subjects. No differences between ascorbic acid and placebo treatments of smokers and nonsmokers were observed for 1-s forced expiratory volume, forced vital capacity, 1-s forced expiratory percent, resting heart rate, resting and postexercise systolic and diastolic blood pressures, treadmill workload, postexercise blood lactic acid, and ventilation measurements. The postexercise systolic blood pressure values of the nonsmokers were lower, although not quite significantly, after the ascorbic acid treatment than after the placebo. The 300-mg ascorbic acid supplement appeared to have little effect on the lung function and physical performance of healthy smoking and nonsmoking males.

Exploratory study of incident vehicle crashes among older drivers.

BACKGROUND: As the number of older adult drivers increases, distinguishing safe from unsafe older adult drivers will become an increasing public health concern. We report on the medical and functional factors associated with vehicle crashes in a cohort of Alabama drivers, 55 years old and older. METHODS: This prospective study involved 174 older adults, on whom demographic, medical, functional, and physical performance data were collected in 1991. Subjects were then followed through 1996 for incident vehicle crashes. RESULTS: Sixty-one subjects experienced between one and four police-reported vehicle crashes during the study period. Following adjustment for age, race, days driven per week, and gender, Cox proportional-hazards models showed the following variables to be associated with crash involvement: reported difficulty with yardwork or light housework (relative risk [RR] = 2.1; 95% confidence interval [CI] 1.1, 4.0; p = .02), or opening ajar (RR = 3. 1; 95% CI 1.4, 6.7; p = .004); at least one crash before 1991 (RR = 2.1; 95% CI 1.2, 3.7; p = .008); using hypnotic medication (RR = 2.9; 95% CI 1.3, 6.6; p = .01); self-reported stroke or transient ischemic attack (RR = 2.7; 95% CI 1.1, 6.6; p = .03); scoring within the depressed range on the Geriatric Depression Scale (RR = 2.5; 95% CI 1.1, 6.0; p = .03), and failing the useful field-of-view test (RR = 1.9; 95% CI 1.0, 3.5; p = .05). CONCLUSIONS: Variables related to function, medication use, affect, neurological disease, and visuocognitive skills were associated with vehicle crash involvement in this cohort. Our findings suggest that multifactorial assessments are warranted to identify at-risk older drivers.

Long-term outcomes in open pelvic fractures.

BACKGROUND: Open pelvic fractures represent one of the most devastating injuries in orthopedic trauma. The purpose of this study was to document the injury characteristics, complications, mortality, and long-term, health-related quality of life outcomes in patients with open pelvic fractures. METHODS: The trauma registry at an adult trauma center was used to identify all multiple system blunt trauma patients with a pelvic fracture from January of 1987 to August of 1995 (n = 1,179). Demographic data, mechanism of injury, and fracture type were determined from hospital records. Short-term outcome measures included infectious complications, mortality, and length of stay in hospital. Long-term outcomes of survivors were obtained by telephone interview using the SF-36 Health Survey and the Functional Independence Measure. RESULTS: Open pelvic fractures were uncommon, occurring in 44 patients (4%). Patients with open fractures were about 9 years younger, on average, than patients with closed fractures (30 vs. 39, p < 0.001). Similarly, patients with open fractures were more likely to be male (75 vs. 57%, p < 0.02), more likely to have been involved in a motorcycle crash (27 vs. 6%, p < 0.001), and more likely to have an unstable pelvic ring disruption (45 vs. 25%, p < 0.001). Open pelvic fracture patients required more blood than closed pelvic fracture patients, both in the first day (16 vs. 4 units, p < 0.001) and during the total hospital admission (29 vs. 9 units, p < 0.001). Five patients with perineal wounds did not receive a diverting colostomy; in turn, these individuals had a total of six pelvic infectious complications (one abscess, two with osteomyelitis, and three perineal wound infections). Overall, 11 patients died, six patients were lost to follow-up, and 27 were long-term survivors (mean duration of 4 years). Chronic disability was common after a pelvic fracture, with problems related to physical role performance and physical functioning, and was particularly severe after an open pelvic fracture (p < 0.05 for both as measured by the SF-36). CONCLUSIONS: Patients with open pelvic fractures often survive, need to be treated with massive blood transfusions, and often require a colostomy. They are frequently left with chronic pain and residual disabilities in physical functioning and physical roles, and many remain unemployed years after injury.

Is dosage of physiotherapy a critical factor in deciding patterns of recovery from stroke: a pragmatic randomized controlled trial.

BACKGROUND AND PURPOSE: The best treatment and management of stroke patients has been shown to be in stroke units by multidisciplinary rehabilitation teams. Since the composition of stroke units differs it is important to know the extent to which the different components contribute to this results. Physiotherapy is one component of most rehabilitation teams and recent systematic reviews have shown that patients with stroke receiving more physiotherapy achieve more recovery from disability. However, information about the actual amounts of physiotherapy needed to achieve this result is not known. METHOD: A pragmatic, randomized, single-blind, controlled trial comparing recovery from disability in subjects receiving the current standard amount of 30 minutes' physiotherapy with those receiving double that amount (60 minutes). The study included measures of physical performance and function, psychological aspects of anxiety and depression, and perceived control over recovery. RESULTS: Some 114 subjects were recruited to the study; full six-week data are available for 104 subjects and six-month data for 93 subjects. Comparison of initial to six-week difference scores in the control and intervention groups of the whole sample did not show a significant difference. Scrutiny of the recovery curves of the whole sample showed that, in half the sample, three distinct patterns of recovery were demonstrated. CONCLUSION: These results suggest that doubling the physiotherapy time available for patients in a stroke unit will not provide a measurable benefit for all patients. The subgroup analysis of patterns of recovery must be regarded as speculative, but provides the basis for hypotheses about those likely to respond well to more intensive therapy.

The National Institute on Aging and the National Cancer Institute SEER collaborative study on comorbidity and early diagnosis of cancer in the elderly.

BACKGROUND: An effect of comorbidity, or the coexistence of other diseases, on the stage of cancer at diagnosis and the appropriateness of therapy in older patients with cancer is hypothesized. The effect of comorbidity differs by cancer site and by type of comorbidity. Such variation could be due to the use of different populations or methods, or the natural history of the tumor being studied. METHODS: The National Institute on Aging (NIA) and the National Cancer Institute (NCI) have initiated a study using cancer patient populations in the NCI's SEER (Surveillance, Epidemiology and End Results) program. Five geographic locations participated in the NIA/NCI pilot study of comorbidity associated with seven cancer sites. Approximately 250 patients with each type of cancer, stratified by age (either 65-74 years of age or 75 years and older) had hospital records abstracted for comorbidity using a form derived from previously reported methods. RESULTS: After analyzing preliminary results for 1712 patients, it was ascertained that more and different chronic disease categories would be necessary, that it was not feasible to collect data on ability to perform certain physical functions from the medical records, and that the collection of data on current medications was possible. With these limitations, relationships of comorbid conditions with stage of cancer were analyzed. CONCLUSION: With the success of the pilot study, the full study is underway. In addition to the planned abstracting of approximately 7800 records, interviews assessing the behavior of illness in a sample of 1000 cancer patients will provide valuable information on the influence of comorbidity and age on stage at initial diagnosis and the treatment of older persons afflicted with cancer.

Effectiveness of Yoga and Combined Exercise in Female With Rheumatoid Arthritis: Randomized Controlled Trial.

BACKGROUND: Although exercise is beneficial for Rheumatoid Arthritis (RA), the comparative efficacy of different modalities for patients in clinical remission remains unclear. This study compared the short- and long-term effects of yoga versus a combined exercise programme on pain, balance, mobility, fatigue, depression, and quality of life in females with RA in remission. METHODS: In this single-blind, randomized controlled trial, 74 female participants were allocated to yoga (n&#xa0;=&#xa0;25), combined exercise (n&#xa0;=&#xa0;25), or a usual care control group (n&#xa0;=&#xa0;24). The intervention groups underwent an 8-week supervised programme. Clinical assessments, including the Visual Analogue Scale (pain), Berg Balance Scale, Timed Up and Go Test, Beck Depression Inventory, Fatigue Severity Scale, and Short Form-36, were conducted at baseline, post-intervention (8&#xa0;weeks), and follow-up (20&#xa0;weeks). RESULTS: Both intervention groups demonstrated significant improvements in all outcome measures compared with the control group at post-treatment and follow-up (p&#xa0;<&#xa0;0.05). Notably, the yoga group exhibited superior outcomes compared to the combined exercise group in reducing pain intensity (median reduction of 4.00 vs. 2.00 points; p&#xa0;<&#xa0;0.001, &#x3b7;2&#xa0;=&#xa0;0.724), as well as in physical function, balance, fatigue, depression, and quality of life at the 20-week follow-up. These benefits may be partly attributed to the incorporation of breathing and relaxation techniques inherent to yoga practice. CONCLUSIONS: Both 8-week yoga and combined exercise programs are effective in managing residual symptoms in females with RA in clinical remission. However, yoga appears to provide superior benefits in pain management and psychosocial well-being, supporting its integration into multidisciplinary RA management protocols, particularly for addressing psychosocial burden in patients achieving remission. TRIAL REGISTRATION: This study was retrospectively registered at NCT07072754 (clinicaltrials.gov).

Blood lipid distributions in older persons. Prevalence and correlates of hyperlipidemia.

Distributions of blood total cholesterol, triglyceride, low-density-lipoprotein (LDL) cholesterol, and high-density-lipoprotein (HDL) cholesterol levels are presented for a geographically defined cohort of rural elderly Iowans, 71 to 102 years old. Cross-sectionally, women had higher levels of total and LDL cholesterol than men did, levels that declined with increasing age. Mean HDL cholesterol levels were also higher in women than in men, but remained relatively constant across the age range. Age- and sex-specific total, LDL, and HDL cholesterol levels were lower among participants residing in long-term-care facilities. HDL but not total cholesterol levels were lower in cigarette smokers and those with chronic illnesses, physical dependence, and poorer performance on physical function tests, and higher among those consuming alcohol. If subjected to the screening guidelines of the National Cholesterol Education Program, a majority of this population, having total cholesterol levels of 5.2 mmol/L (200 mg/dL) or higher, would require further evaluation for possible hyperlipidemia.

Geriatric assessment.

A comprehensive geriatric assessment involves the evaluation of the physical, psychosocial, and environmental factors affecting the health of an elderly person. In the office setting a geriatric assessment is best accomplished by the use of screening questions, which are incorporated into the patient's medical questionnaire; the use of validated, brief screening tests that measure the patient's performance of daily living activities, cognition, nutritional status, and risk of falls; and a review of the patient's personal values and social support network. The screening assessment can be completed in an average of ten minutes by using self-administered questionnaires and brief performance-based measures of physical functioning. The comprehensive assessment performed on the initial visit with an elderly patient will help to (1) improve diagnostic accuracy, (2) guide the selection of interventions to restore or preserve health, (3) recommend an optimal environment for care, (4) predict health outcomes, and (5) monitor clinical change over time. The effectiveness of geriatric assessment has been demonstrated in clinical trials and is likely to be most effective when conducted by the patient's primary care physician.

Androgen effects on body composition.

Androgens are known to have a role in the body fat, muscle size, muscle performance and physical function differences seen between hypogonadal and eugonadal men. The results of investigations into effects of testosterone on body composition, fat metabolism and muscle anabolism are reviewed here. Testosterone dose-response relationships are presented in studies of the effects of physiologic and supraphysiologic doses with and without exercise in young hypogonadal men, older men with low testosterone levels and in chronic illness states.

The use of a simple Likert scale to measure quality of life in brain tumor patients.

The use of a self-administered 10-Point Likert self-assessment quality of life scale was explored in a convenience sample of patients attending a brain tumor clinic. The original scale, developed by Priestman, was modified to be more brain-tumor specific. A total of 430 patients completed the scale at 535 different points of measurement. The patients had a variety of brain tumors ranging from meningiomas to high-grade gliomas. The Total Score of the original scale and the Modified Total Score of the brain-specific version were explored in relationship to patient demographics and available clinical characteristics: age, gender, severity of tumor, location of tumor, survival rates, prior surgery, radiation, radiosurgery, and chemotherapy. We also examined the relationship between sub-scales and these variables. On a scale of 10-100, the average Total Score was 67.83, not significantly different from the Modified Score. There were no differences between bilateral, midline, or left- versus right-sided lesions. Patients with the worst prognosis in terms of tumor type were 5-6 points lower in quality of life than patients with intermediate or relatively good prognosis. In a multiple regression model, adjusted for age, the overall score was related only to tumor severity and to gender, with women having significantly poorer functional status than men by 4 points. Both the Modified and Total Scores were significantly associated with higher mortality risk, and more specifically, poor scores on well-being, mood, physical function, house/job performance, self-care, concentration, and energy all predicted higher mortality risk. We suggest that the simplicity of this instrument may make it particularly useful for longitudinal assessment of quality of life in brain tumor patients.

Comparison of health-related quality of life in three subgroups of spinal cord injury patients.

Health-related quality of life (HRQL) was evaluated in three subgroups of spinal cord injury (SCI) patients: (1) persons who had sustained a pediatric SCI (mean time from injury 20 years, age at injury 11.3 years, n = 36), (2) newly injured patients at the beginning of acute rehabilitation (mean age 35.3 years, n = 31), and (3) patients with a chronic SCI (mean time from injury 4.8 years, mean age at injury 35.2 years, n = 34). All the patients were clinically examined and structurally interviewed with a list of questions dealing with details of anamnestic information about injury, its treatment, possible complications and persons past and present psycho-social condition. HRQL was assessed by a generic fifteen-dimensional self-administered instrument (15D). The relative importance of the 15D dimensions and an overall judgement of health status were measured by a 0-100 visual analogue scale. Average importance weights of the dimensions of moving and working differed significantly in the three subgroups. Patients with pediatric SCI assigned the lowest importance for moving. The newly injured patients highly valued working capability. The HRQL scores of the patients who had sustained their injury in childhood were significantly higher than those of the newly injured patients or chronic patients. The tetraplegic patients estimated their HRQL significantly lower than patients with incomplete paraplegia. Of the three subgroups studied, those with pediatric SCI were well adjusted on the basis of anamnestic information and scored high on HRQL when compared with the other two subgroups. Patients injured in adulthood rated their overall HRQL lower and were often unable to return to work. Patients injured in childhood expressed better performance in physical functions than patients who had sustained their injury in adulthood. The subgroups did not differ in psychological functions.

The interrelationship of weight loss, dietary intake, and quality of life in ambulatory patients with cancer of the lung, breast, and ovary.

One hundred four consecutive patients with newly diagnosed small cell lung cancer, metastatic breast cancer, and ovarian cancer in good physical functional condition (performance rating 0-1 on Eastern Cooperative Oncology Group scale) were divided into a weight-losing group (> or = 5% unintentional weight loss within 3 mo; n = 48) and a weight-stable group (n = 56). Dietary intakes in relation to fat-free mass were not different in the two groups. According to the Quality of Life index and the General Health Questionnaire, weight-losing patients had significantly lower quality of life than weight-stable patients. In patients with weight loss, daily intakes of energy and protein correlated significantly with scores on the General Health Questionnaire. This study has shown that many ambulatory cancer patients do not eat enough to maintain weight and that even a moderate weight loss is associated with psychological distress and lower quality of life.

Determinants of compliance with antiretroviral therapy in patients with human immunodeficiency virus: prospective assessment with implications for enhancing compliance.

Non-compliance with therapy is a significant problem, particularly when the disease process is chronic and therapeutic regimens are employed for prolonged periods. We assessed the prevalence and variables associated with compliance with antiretroviral therapy in patients with human immunodeficiency virus infection, by means of a longitudinal observational study of 46 patients aged 23 to 68 years, with human immunodeficiency virus infection, followed at the Pittsburgh VA Medical Center. Data on demographics, medical status, physical functioning (Karnofsky performance scores), CD4 lymphocyte count, depression (Beck depression inventory), coping (inventory of coping with illness scale scores), and psychological and emotional stress (profile of mood states scale scores), were prospectively assessed on all patients at baseline and every 6 months. Compliance was assessed at 6 and 12 months: patients taking > or = 80% of antiretroviral therapy were considered compliant. Overall, 63% of patients were compliant with antiretroviral therapy. Age, education, employment, religious support, and perceived quality of life did not correlate with compliance. By univariate analysis, lack of prior intravenous drug use was significantly associated with compliance (p = 0.01). Compliant patients had significantly better adaptive coping (p = 0.03), and less depression (p = 0.04). By multivariate analysis, black race was significantly associated with non-compliance independent of intravenous drug use and educational status. History of prior opportunistic infection (which presumably heightens the perceived severity of illness) (p = 0.02), and lesser psychological disturbance scores (p = 0.02) were associated with compliance. Compliance was observed despite the greater number of prescription medications taken by compliant patients (p = 0.04). At 12 months, Karnofsky scores were better in compliant patients (p = 0.02), although mortality was not different. Besides identifying predictors of compliance, our data suggest that symptoms of depression and psychological stress be sought in patients with non-adherence.
