Anticholinergic drugs and physical function among frail elderly population.

Increasing evidence from experimental studies and human observations suggests that drugs with anticholinergic properties can cause physical and mental impairment. The aim of this study was to evaluate the relationship between the use of drugs with anticholinergic activity and measures of physical performance, muscle strength, and functional status in persons aged 80 years or older. Data are from baseline evaluation of 364 subjects enrolled in the ilSIRENTE study. The ilSIRENTE study is a prospective cohort study performed in the mountain community living in the Sirente geographic area (L'Aquila, Abruzzo) in Central Italy. Physical performance was assessed using the physical performance battery score (Short Physical Performance Battery), which is based on three timed tests: 4-meter walking speed, balance, and chair stand tests. Muscle strength was measured by hand grip strength. We defined as anticholinergic drugs all medications for which serum anticholinergic activity was previously demonstrated. Analyses of covariance were performed to evaluate the relationship of anticholinergic drugs with physical function. In the unadjusted model, all the physical performance, muscle strength, and functional measures showed significant associations with the anticholinergic drug use. After adjustment for potential confounders (age, gender, smoking, physical activity level, cognitive performance score, living alone, body mass index, congestive heart failure, lung diseases, diabetes), these associations were weaker but still statistically significant (physical performance battery score: non-users anticholinergic drugs 6.9, SE 0.1, users anticholinergic drugs 6.1, SE 0.2, P=0.05; hand grip strength: non-users anticholinergic drugs 31.3 kg, SE 0.8, users anticholinergic drugs 28.8 kg, SE 1.0, P=0.05; Activities of Daily Living scale score: non-users anticholinergic drugs 1.2, SE 0.1, users anticholinergic drugs 1.6, SE 0.1, P=0.03; Instrumental Activities of Daily Living scale score: non-users anticholinergic drugs 2.7, SE 0.1, users anticholinergic drugs 3.4, SE 0.1, P<0.001). The use of medication with anticholinergic properties is common among community older subjects in Italy. Our results suggest that among old-old subjects the use of anticholinergic drugs is associated with impaired physical performance and functional status.

Functional decline in frail community-dwelling stroke patients.

Patients who suffer a stroke event are at high risk of functional decline after the post-acute rehabilitation period. The aim of the present study was the evaluation of factors associated with functional decline in a large sample of older patients with stroke living in the community. The study population consisted of all patients admitted to home care programs after a post-acute rehabilitation program--with at least 1 year of follow-up--in twenty-two Italian Home Health Agencies from 2000 to 2002 (n=1338). For the present study we selected 355 (26%) patients with diagnosis of stroke. After 1 year of in-home care program, 149 out of 355 stroke survivors (42%) had presented a worsening in the activities of daily living (ADL) scale score. In the final adjusted model, patients with cognitive impairment (OR 2.59, 95% CI, 1.45-4.64), pressure ulcer (OR 2.74, 95% CI, 1.45-5.18), urinary incontinence (OR 1.64, 95% CI, 1.01-3.29), or hearing impairment (OR 1.83, 95% CI, 1.02-3.29) were more likely to significantly decline in physical functioning after a period of 1 year in-home care program. Our study documents that functional decline of stroke patients was largely dependent on specific subjects' clinical characteristics. Three of four concomitant disabling conditions associated in our sample with functional decline--pressure ulcer, urinary incontinence, hearing--can be prevented and eventually treated or modified. Appropriate post-acute rehabilitation programs and adequate home care interventions focused on the prevention and treatment of these conditions might be correlated to better outcomes in older post-stroke patients.

Lifetime occupation and physical function: a prospective cohort study on persons aged 80 years and older living in a community.

BACKGROUND: Several studies have reported predictors for loss of mobility and impairments of physical performance among frail elderly people. AIM: To evaluate the relationship between lifetime occupation and physical function in persons aged 80 years or older. METHODS: Data are from baseline evaluation of 364 subjects enrolled in the ilSIRENTE study (a prospective cohort study performed in a mountain community in Central Italy). Physical performance was assessed using the physical performance battery score, which is based on three timed tests: 4-metre walking speed, balance, and chair stand tests. Muscle strength was measured by hand grip strength. Lifetime occupation was categorised as manual or non-manual work. RESULTS: Mean age of participants was 85.9 (SD 4.9) years. Of the total sample, 273 subjects (75%) had a history of manual work and 91 subjects (25%) a history of non-manual work. Manual workers had significant lower grip strength and physical performance battery score (indicating worse performance) than non-manual workers. After adjustment for potential confounders (including age, gender, education, depression, cognitive performance scale score, physical activity, number of diseases, hearing impairment, history of alcohol abuse, smoking habit, and haemoglobin level), manual workers had significantly worse physical function (hand grip strength: non-manual workers 32.5 kg, SE 1.4, manual workers 28.2 kg, SE 0.8; physical performance battery score: non-manual workers 7.1, SE 0.4, manual workers 6.1, SE 0.2). CONCLUSIONS: A history of manual work, especially when associated with high physical stress, is independently associated with low physical function and muscle strength in older persons.

Analysis of circulating gammadelta T cells in children affected by IgE-associated and non-IgE-associated allergic atopic eczema/dermatitis syndrome.

Recent studies have suggested that not only alphabeta(+) T cells, but also the less common gammadelta(+) T cells may play a role as effectors and immunoregolatory cells in the development and perpetuation of allergic inflammation. The objective of this study was to focus on the role of gammadelta(+) T cells in atopic dermatitis (AD), a chronic relapsing inflammatory disease of the skin, often associated with allergic bronchial asthma. The present study employed flow cytometric analysis to compare numbers and phenotypic characteristics of gammadelta(+) T cells in the peripheral blood of children with atopic dermatitis and age-matched healthy controls. The percentage of circulating Vgamma 9Vdelta2(+) T lymphocytes was significantly increased in AD patients with respect to the age-matched controls, with a positive correlation with clinical score severity. The prevalent phenotype in both AD patients and controls was CD45RO(+), with no differences observed in the percentage of Vdelta2(+) CD45RO(+) between these groups. Conversely, memory CD45RO(+) CD62L(+) Vdelta2(+) lymphocytes were significantly lower in AD patients. Furthermore, naive circulating Vdelta2(+) T lymphocytes were significantly lower in AD children than in aged-matched controls. No correlation was observed between circulating Vgamma 9Vdelta2(+) expansion and IgE serum levels. It was concluded that an association exists between the levels of circulating gammadelta(+) T lymphocytes and atopic dermatitis, with a positive correlation with clinical score but no link with IgE serum levels. The pathophysiological role of gammadelta T lymphocytes in atopic dermatitis awaits further investigation.

Emotional and interpersonal factors are most important for patient satisfaction with anaesthesia.

BACKGROUND: Questionnaires to evaluate patient satisfaction with anaesthesia mainly consider physiological aspects. This study was performed to identify the items of value for patients having anaesthesia (pilot phase) and to validate the questionnaire built on these findings in a new group of inpatients. METHODS: In the pilot phase, 100 surgical patients were interviewed and asked whether each of the 23 items selected by a panel of providers was relevant (score 1) and to rank these from 1 (additional score 6) to 5 (additional score 2). The resulting 10-item final instrument was administered to 219 consecutive inpatients by interview, after recent anaesthesia, asking them how much of each item they received (item received) and the level of satisfaction with the same item, using Numerical Rating Scales (range 0-10). RESULTS: In the pilot phase, gender, age, education and surgery did not influence the score enough to change the first 10 rank-ordered items. The 219 patients subsequently studied did not differ from those missing the questionnaire administration. The patients aged less than 55 years showed lower satisfaction scores than those aged 55 years or more (P = 0.019). In all items, except 'feeling anxious/frightened', the item received was significantly associated with the satisfaction reported. 'Kindness/regard of caregivers' together with 'information given by anaesthetist' and 'feeling safe' predicted 47% of the variance in total patient satisfaction. CONCLUSIONS: Inpatients value highly those elements of care that pertain to emotional and interpersonal relationships.

Physical activity and behavior in the elderly: a pilot study.

Although exercise is usually promoted for weight loss and better heart health, there is growing evidence that regular physical activity helps people preserve their mental ability. We describe the results of a pilot longitudinal study addressing the impact of a moderate intensity exercise program on behavioral problems of frail, elderly, demented patients living in nursing home. Overall, patients in the treatment group (combination of aerobic/endurance activities, strength training, balance, and flexibility training) showed a statistically significant reduction in the behavioral problems, such as wandering, physical and verbal abuse, and in the sleep disorders. As a consequence, a significant reduction in the use of antipsychotic and hypnotic medications was observed in subjects of the treated group. In conclusion, our preliminary results suggest that engaging in regular physical activity,among other health benefits, may delay or prevent the onset of behavior problems in demented frail elderly people living in nursing home.

Skin tolerability and efficacy of combination therapy with hydrogen peroxide stabilized cream and adapalene gel in comparison with benzoyl peroxide cream and adapalene gel in common acne. A randomized, investigator-masked, controlled trial.

BACKGROUND: Combination therapy with antiseptics such as benzoyl peroxide (BP) and topical retinoids is widely used as first-line treatment for acne vulgaris (AV). However, these combinations could have a suboptimal skin tolerability. Recently, a new formulation of hydrogen peroxide (HP) 1% in stabilized cream (Crystacide; Mipharm, Milan, Italy) became available. A previous clinical study has shown that HP cream monotherapy presents a better skin tolerability in comparison with BP in patients with mild AV. OBJECTIVES: To evaluate the tolerability and the efficacy of combination therapy with HP cream and adapalene 0.1% gel in comparison with the combination of BP 4% cream and adapalene 0.1% gel in the treatment of mild to moderate AV. METHODS: In a randomized, investigator-blinded trial, 52 patients (mean +/- SD age 25 +/- 6 years; 19 men and 33 women) with AV were randomly assigned to HP cream and adapalene gel (group HP + A) or to BP cream and adapalene gel (group BP + A), for eight consecutive weeks. Efficacy was assessed by total (TL), inflammatory (IL) and noninflammatory (NL) lesion counts performed at baseline and weeks 4 and 8. Tolerability was assessed by evaluating skin erythema, burning and dryness at weeks 4 and 8. RESULTS: All patients completed the study. At baseline, the mean +/- SD numbers of TL, IL and NL were 44 +/- 9, 25 +/- 7 and 19 +/- 6 in group HP + A and 40 +/- 9, 21 +/- 7 and 19 +/- 9 in group BP + A, respectively. At the end of the treatment period, TL, IL and NL were reduced by 93%, 92% and 95%, respectively, in group HP + A and by 88%, 86% and 90%, respectively, in group BP + A. A significantly (P = 0.0025) greater reduction in NL was observed in group HP + A in comparison with group BP + A. Tolerability was significantly better in group HP + A in comparison with group BP + A (P = 0.02). Skin dryness and burning sensation were more frequent in group BP + A. CONCLUSIONS: The combination of adapalene and HP cream is an effective topical treatment regimen in mild to moderate AV. This combination has shown a better tolerability profile in comparison with the combination of BP and adapalene.

Antithrombotic drugs in secondary stroke prevention among a community dwelling older population.

BACKGROUND: Patients who suffer a cerebrovascular event are at high risk of a recurrence. Secondary prevention is crucial in reducing the burden of cerebrovascular disease. OBJECTIVE: To estimate the percentage of stroke survivors receiving antiplatelet or anticoagulant drugs and to identify factors associated with such treatment. DESIGN: Cross sectional retrospective cohort study. METHODS: Data were analysed from a large collaborative observational study, the Italian "silver network" home care project, which collected data (from 1997 to 2001) on patients admitted to home care programmes (n = 5372). Twenty two home health agencies participated in evaluating the implementation of the minimum dataset for home care (MDS-HC) instrument. For the present study, 648 individuals with a diagnosis of stroke were selected and the initial MDS-HC assessment reported. RESULTS: 70% of stroke survivors did not receive any antiplatelet or anticoagulant drugs (95% confidence interval (CI), 66.5 to 73.5). Among all age categories, aspirin and ticlopidine were the two most commonly prescribed drugs. Living alone (odds ratio (OR), 0.49 (95% CI, 0.24 to 0.89)), dependency in activities of daily living (0.66 (0.40 to 0.99)), cognitive impairment (0.58 (0.38 to 0.86)), and low educational level (0.58 (0.34 to 0.98)) were associated with a reduced likelihood of receiving secondary stroke prevention treatment. Cardiac arrhythmias, coronary artery disease, heart failure, and peripheral vascular disease were associated with the use of antiplatelet or anticoagulant treatment. CONCLUSIONS: Negative attitudes among physicians with respect to secondary stroke prevention are prevalent and reinforce the need for increased awareness of existing data on the risks and benefits for elderly individuals. Social problems and functional impairment may be issues concerning physicians when deciding whether or not the risks of treatment exceed the benefit.

Gender differences in predictors of mortality in nursing home residents with AD.

OBJECTIVE: To evaluate whether the excess mortality in men with AD can be explained by a gender difference in the predictors of mortality. METHODS: The authors studied 2,838 men and 6,385 women over 65 years of age with AD admitted, between 1992 and 1995, to 1 of nearly 1,500 nursing homes in five U.S. states (Kansas, Maine, Mississippi, New York, and South Dakota). Resident level data including sociodemographic characteristics, dementia severity, measures of physical disability, comorbidity, and other clinical variables were collected with the Minimum Data Set. Information on death was derived through linkage to Medicare enrollment files; the median follow-up was 23 months. Baseline characteristics were used to predict age at time of death in Cox proportional hazard models. RESULTS: Men with AD had an increased risk of mortality relative to women, adjusted for differences in the distribution of age and race. The most important predictors of death in men were those related to the disease itself. These were the severity of dementia and the occurrence of episodes of delirium. Instead, death among women was associated with measures of disability, namely, impairment in performing the activities of daily living, presence of pressure sores, malnutrition, and comorbidity. CONCLUSION: These data suggest that the underlying mechanisms for AD may be different in men and women. Future studies of survival and progression of AD need to examine men and women separately.

Treatment of osteoporosis among older adults discharged from hospital in Italy.

OBJECTIVE: Osteoporosis and its complications represent one of the most important causes of morbidity and mortality among the elderly. Despite the availability of several drugs deemed effective at reducing the incidence of fractures, only a minority of patients receive pharmacological treatment. We studied patients with a diagnosis of osteoporosis at discharge from hospital in Italy to identify predictors of receiving specific pharmacological treatment and to analyse how the pattern of drug prescription has changed in the last decade. METHODS: We analysed data from a multicentre pharmacoepidemiology study that collected data on hospitalised patients throughout Italy. Patients with a diagnosis of osteoporosis admitted during five different surveys in 1988, 1991, 1993, 1995 and 1997 were considered for the present study. RESULTS: Of 863 patients with a diagnosis of osteoporosis, 461 (53.4%) received treatment. Age [odds ratio (OR) 0.86 for each decade of increment, 95% confidence interval (CI) 0.73, 0.99], male gender (OR 0.67, 95% CI 0.44, 0.99), number of comorbid conditions (4-5 vs. 0-3 conditions: OR 0.66, 95% CI 0.47, 0.91; 6 or more vs. 0-3 conditions: OR 0.47, 95% CI 0.31, 0.72) and number of medications (OR 0.92 for each drug increase, 95% CI 0.85, 0.99) were all associated with a reduced likelihood of receiving pharmacological treatment for osteoporosis. In contrast, concomitant corticosteroid use (OR 2.00, 95% CI 1.05, 3.80), admission for hip or vertebral fracture (OR 2.10, 95% Cl 1.12, 3.93) and year of survey (OR 1.11, 95% CI 1.01, 1.24) were independent predictors of a higher treatment rate. Among individual drugs, calcitonin use remarkably declined from 42.1% in 1988 to 0.8% in 1997 (P for trend <0.001), while bisphosphonate prescriptions increased from 1.3% in 1988 to 34.9% in 1997 (P for trend <0.001). Prescription of calcium did not change significantly throughout the decade examined, while vitamin D had a twofold increase (14.2% in 1988 to 26.2% in 1997, P for trend <0.001). CONCLUSIONS: Among patients discharged from hospital in Italy, osteoporosis is an uncommon diagnosis. Even when the diagnosis is made, osteoporosis is often undertreated, and treatment is reserved for younger and less medically complex patients.

A new model of integrated home care for the elderly: impact on hospital use.

The objective of the present study was to examine the effect of a home care program based on comprehensive geriatric assessment-Minimum Data Set for Home Care-and case management on hospital use/cost of frail elderly individuals. We determined all hospital admissions and days spent in hospital during the first year since the implementation of the home care program, and compared them to the rate of hospitalization that the same patients had experienced in the year preceding the implementation of such program. Following the implementation of this program, there was a significant reduction of the number of hospitalizations (pre 44% vs. post 26%, P < 0.001), associated with a reduction of hospital days, both at the individual patient level and for each admission. In conclusion, an integrated home care program based on the implementation of a comprehensive geriatric assessment instrument guided by a case manager has a significant impact on hospitalization and is cost-effective.

Trends in antihypertensive drugs in the elderly: the decline of thiazides.

The last decade has seen the publication of different editions of guidelines for the pharmacological treatment of hypertension that were based on the results of large, randomised trials. Since these guidelines were meant to inform practitioners, we analysed the pattern of prescription of antihypertensive agents between 1988 and 1997 among older hospitalised adults. Because of the wealth of data supporting the use of thiazides diuretics, we focused on diuretic prescription, to identify independent predictors of their utilisation. To this end, we used the GIFA database that includes patients admitted to academic medical centres throughout Italy between 1988 and 1997. We studied 5061 patients over 65 years of age selected among a population of 28 411, based on the diagnosis of arterial hypertension at discharge. The use of ACE-inhibitors has been raising steadily through the years, and they are the agents most commonly used since 1996. Calcium channel blockers showed a similar trend and were the top prescribing drug until 1995; afterwards, the documentation of potentially severe side effects has resulted in a nearly 20% reduction of their use. Beta-blockers have remained unpopular throughout the decade. Instead, the prescription of diuretics as a class showed a biphasic trend; an initial decrease with a prolonged steady state and a more recent raise. However, at a separate analysis, it was a evident that a progressive increase of the use of loop diuretics since 1988 has been paralleled by a nearly 50% reduction of thiazides prescriptions. Loop diuretics were more likely to be prescribed to older individuals, those with cardiac heart failure, coronary heart disease and high creatinine level. In contrast, independent predictors of thiazides use were female gender, good functional status, preserved renal function, and absence of cardiovascular comorbidity. In conclusion, despite continued recommendations to use thiazides diuretics for the treatment of hypertension among older individuals, their use has been declining steadily between 1988 and 1997. A possible explanation is that the choice to prescribe a thiazides diuretic is influenced by age, functional status and comorbidity.

Impact of a new assessment system, the MDS-HC, on function and hospitalization of homebound older people: a controlled clinical trial.

OBJECTIVES: To evaluate the impact of a new assessment system, the Minimum Data Set for Home Care (MDS-HC), on the functional status and hospitalization rates of frail, community-dwelling older people. DESIGN: Single-blind randomized trial with 1-year follow-up. SETTING: Bergamo, Italy. PARTICIPANTS: All 187 subjects who were eligible for home care services delivered by two Health Districts between September 1998 and April 1999. INTERVENTION: Random allocation to an intervention group undergoing MDS-HC assessment or to a control group receiving conventional geriatric assessment with Barthel, Lawton and Brody, and Mini-Mental State Examination (MMSE) scales. MEASUREMENTS: Hospitalization, health services use and costs, and variations in functional status. RESULTS: Survival analysis indicated that the intervention group was admitted to the hospital later and less often than were controls (relative risk = 0.49, 95% confidence interval = 0.56-0.97). Health services were used to the same extent, but intervention subjects used more in-home help services. Total costs for the intervention group were 21% lower than for the control group. The adjusted mean scores of the activities of daily living index (51.7+/-36.1 vs 46.3+/-33.7; P = .05) and MMSE (19.9+/-8.9 vs 19.2+/-10.7; P = .03) were significantly improved in the intervention group as compared with the control group. CONCLUSIONS: The MDS-HC assessment instrument may provide a cost-saving approach to reducing institutionalization and functional decline in older people living in the community.

Functional status and clinical correlates in cognitively impaired community-living older people.

We describe the prevalence of cognitive impairment in a population of community-living older people, its association with functional decline, and degree of comorbidity. In addition, we examined the relationship between different levels of cognitive impairment and mortality. We conducted an observational study of 1787 patients aged 65 years and above with any degree of cognitive impairment. Patient data were collected with the Minimum Data Set for Home Care. More than 50% of patients had some level of cognitive impairment, which correlates with the degree of physical frailty. On the contrary, patients with cognitive impairment appear to have fewer comorbid conditions and are less likely to receive medications than patients with normal cognitive status. In particular, hypertension, congestive heart failure, chronic obstructive pulmonary disease, cancer, diabetes mellitus, and osteoporosis are found more frequently among patients with normal mental status compared with those showing some level of cognitive defects. Yet, more severe cognitive impairment is associated with a higher mortality rate. Demented patients are characterized by a high prevalence of functional disability and by increased mortality. This increased morbidity and mortality rate is associated with a lower prevalence of comorbid clinical conditions and drug use, relative to patients with normal cognitive performance. The present findings support the possibility that severe cognitive impairment has an independent effect on survival.

Physical restraint and subcutaneous hematoma in an anticoagulated patient.

A large subcutaneous hematoma extending from the breastbone region to the left axillary region and left flank developed in a 86-year-old anticoagulated man because of repeated microtrauma from a physical restraint used to prevent his rising from a chair. Physicians, nurses, and physiotherapists should recognize that physical restraints causing pressure on the skin increase hemorrhagic risk in patients who take low molecular weight heparin. Accordingly, they should systematically check for hemorrhagic complications and attempt to limit the use of such devices.

Dose-related impact of alcohol consumption on cognitive function in advanced age: results of a multicenter survey.

BACKGROUND: Moderate alcohol consumption has been associated in several studies with decreased risk of cardiovascular and cerebrovascular events; however, available data on the effects of alcohol intake on cognitive functioning are conflicting. We assessed the association between alcohol consumption and cognitive impairment in a series of older subjects enrolled in a multicenter pharmacoepidemiology survey. METHODS: The association between average alcoholic intake and cognitive performance was assessed in 15,807 patients admitted to participating centers during the survey periods. Demographic variables, comorbid conditions, medications, and objective tests that were associated with cognitive impairment (as indicated by a Hodkinson Abbreviated Mental Test score <7) in separate logistical regression models were examined as potential confounders in a summary model. RESULTS: Cognitive impairment was detected in 1693 (19%) of 8755 drinkers and 2008 (29%) of 7052 nondrinkers (Fisher's exact test, p < 0.0001). After adjusting for potential confounders, alcohol consumption was associated with decreased probability of cognitive impairment (odds ratio, 0.75; 95% confidence interval, 0.66-0.85). The relationship between drinking level and cognitive dysfunction was nonlinear, because the probability of cognitive impairment was decreased for moderate alcohol use as compared with abstinence, but it was increased for daily consumption exceeding one wine-equivalent liter among men and 0.5 liter among women. This nonlinear association persisted when cerebrovascular and Alzheimer's disease were considered separately. CONCLUSIONS: Alcohol abuse is associated with increased prevalence of cognitive dysfunction among older subjects; however, a daily alcohol consumption of less than 40 g for women and 80 g or less for men might be associated with a decreased probability of cognitive impairment. This possible protective effect of alcohol consumption should be further assessed by prospective studies.
