RESUMO

BACKGROUND: Forkhead box O3A (FOXOA3) and apolipoprotein E (APOE) are arguably the strongest gene candidates to influence human exceptional longevity (EL, i.e., being a centenarian), but inconsistency exists among cohorts. Epistasis, defined as the effect of one locus being dependent on the presence of 'modifier genes', may contribute to explain the missing heritability of complex phenotypes such as EL. We assessed the potential association of epistasis among candidate polymorphisms related to physical capacity, as well as antioxidant defense and cardiometabolic traits, and EL in the Japanese population. A total of 1565 individuals were studied, subdivided into 822 middle-aged controls and 743 centenarians. RESULTS: We found a FOXOA3 rs2802292 T-allele-dependent association of fibronectin type III domain-containing 5 (FDNC5) rs16835198 with EL: the frequency of carriers of the FOXOA3 rs2802292 T-allele among individuals with the rs16835198 GG genotype was significantly higher in cases than in controls (P < 0.05). On the other hand, among non-carriers of the APOE 'risk' ε4-allele, the frequency of the FDNC5 rs16835198 G-allele was higher in cases than in controls (48.4% vs. 43.6%, P < 0.05). Among carriers of the 'non-risk' APOE ε2-allele, the frequency of the rs16835198 G-allele was higher in cases than in controls (49% vs. 37.3%, P < 0.05). CONCLUSIONS: The association of FDNC5 rs16835198 with EL seems to depend on the presence of the FOXOA3 rs2802292 T-allele and we report a novel association between FNDC5 rs16835198 stratified by the presence of the APOE ε2/ε4-allele and EL. More research on 'gene*gene' and 'gene*environment' effects is needed in the field of EL.

RESUMO

BACKGROUND: Delirium is one of the most frequent complications of hospitalization in elderly patients. Its influence on prognosis in patients admitted for acute cardiac diseases is not well known. The objective of this study is to assess the incidence of delirium and its impact on clinical and functional outcomes in older patients hospitalized for acute cardiac diseases. METHODS: We prospectively analyzed 203 patients aged 75years or older admitted to a cardiology unit. Delirium was diagnosed with the Confusion Assessment Method. Logistic regression analysis was used to assess independent predictors of in-hospital delirium and to examine the independent risk of mortality, readmission, functional decline, and need for new help at discharge, at 1month and 12months associated with the development of delirium, after adjusting for age, comorbidity, and initial diagnosis. RESULTS: The incidence of delirium was 17.2%. Patients with delirium were older (83±5 vs 81±5years, P=.016) and showed a higher prevalence of major geriatric syndromes (82.9% vs 54.5%, P=.002). Aggressive ventilation modes, urinary catheters, prolonged fluid therapy, night treatments, longer immobilization, and physical restrain were associated with the incidence of delirium. Patients with delirium presented longer stays (8.9±6.2 vs 6.5±4.0days, P=.016) and a greater adjusted risk of functional decline at discharge (odds ratio 2.94, 95% CI 1.10-7.86, P=.032) and of 12-month mortality (odds ratio 4.20, 95% CI 1.81-9.74, P=.001). CONCLUSION: Delirium is a common preventable complication in older patients with acute cardiac diseases. It is associated with poorer in-hospital functional and clinical outcomes, and increased postdischarge mortality.

RESUMO

OBJECTIVES: the aim of this study is to know the prevalence of sarcopenia in geriatric outpatient clinics using the EGWSOP (European Working Group on Sarcopenia in Older People) diagnostic criteria that include muscle mass, muscle strength and physical performance. METHODS: subjects over 69 years old, able to walk without help and who attended five geriatric outpatient clinics were recruited. Body composition was assessed using bioimpedance analysis (BIA), grip strength using a JAMAR dynamometer and physical performance by the 4 m gait speed. Sarcopenia was diagnosed using the EGWSOP criteria (gait speed <0.8 m/s; grip strength <30 kg in men or <20 kg in women, and muscle mass index (MMI) <8.31 kg/m(2) in men or <6.68 kg/m(2) in women). RESULTS: two hundred and ninety-eight subjects were included (median age 83.2 years, 63.1% women). 19.1% had sarcopenia (12.7% men, 22.9% women); 20.1% had low muscle mass; 68.8% had low gait speed and 81.2% low grip strength. Only 21.9% of the subjects with low grip strength and 19.5% of those with low gait speed had sarcopenia. No correlations between muscle mass and either muscle strength or gait speed were detected. CONCLUSIONS: sarcopenia is present in one out of five subjects attending geriatric outpatient clinics.

RESUMO

BACKGROUND/OBJECTIVES: Hospitalization due to acute illness in older patients is often associated with anxiety or depressive symptoms. In these circumstances, given that pharmacologic treatment should be avoided to reduce interactions with ongoing medication regimes, psychotherapy techniques should be considered. The purpose of this study was to evaluate the effectiveness of group reminiscence therapy (RT) on the reduction of anxiety and depressive symptoms in acutely hospitalized older patients. METHODS: Controlled and prospective study conducted on the Acute Geriatric Unit of a university hospital. Patients included in the intervention group (RT Group) attended a group session focused on RT, whereas those included in the control group (UC) received usual hospital care. Exclusion criteria were severe cognitive impairment, impossibility to mobilize, and clinical/hemodynamic instability. The intervention was based on a multi-task daily group session of reminiscence activities. The severity of anxiety (Hamilton Anxiety Rating Scale, HAM-A), depressive symptoms (15-item Geriatric Depression Scale, GDS-15), loneliness (ESTE-II social loneliness scale), and fear of death (Collet-Lester scale) was assessed at admission and discharge in both groups. RESULTS: The intervention was effective in reducing the proportion of patients with anxiety and depressive symptoms during hospitalization. The proportion of patients with moderate-severe anxiety at discharge was 32.1% in the UC and 13.4% in the RT Group (p < 0.001), whereas the proportion of patients with depressive symptoms at discharge was 49.1% in the UC and 19.5% in the RT Group (p < 0.001). The intervention was independently associated with benefits on anxiety levels (RR 2.45, 95% CI 1.83-3.28) and depression (RR 3.71, 95% CI 2.22-6.19) at discharge. No differences were found in loneliness or fear of death. CONCLUSIONS: A group reminiscence activity reduces the proportion of patients with anxiety and depressive symptoms during hospitalization for an acute disease. Absolute changes in both anxiety and depression scores, even though significant, were relatively small.

RESUMO

PURPOSE: To analyze differences in the therapeutic approach to and tumor-related mortality of young and elderly colorectal cancer (CRC) patients. PATIENTS AND METHODS: This was a descriptive study of a retrospective cohort, based on administrative databases, of all patients with CRC diagnosed or treated in our institution. We extracted data on sociodemographic characteristics, comorbidity, type of cancer, type of treatment received, survival time, and cause of death. We compared differences between a young group (YG) (age <75 years) and an older group (OG) (age ≥75 years) and assessed the variables associated with receiving different therapeutic options (multivariate analysis) and with survival time (Cox proportional hazards models). RESULTS: The study included 503 patients (YG, 320; OG, 183), with mean ages of 63.1 years in the YG and 81.8 years in the OG. No differences were observed between the groups in degree of differentiation, extension, tumor stage, or comorbidity. After adjustment for gender, comorbidity, and tumor localization and extension, YG patients were more likely than OG patients to receive surgery, radiotherapy, and chemotherapy and less likely to receive palliative care. After a median follow-up of 36.5 months, YG patients had a longer tumor-specific survival time than OG patients (36.41 months vs 26.05 months). After further adjustment, the YG had a lower tumor-specific mortality risk (hazard ratio, 0.66) than the OG. CONCLUSION: In comparison with younger patients, elderly CRC patients are undertreated, mainly because of their age and not because of their tumor type or comorbidity. Elderly patients have a significantly shorter tumor-specific survival time, partially because of this undertreatment.

RESUMO

BACKGROUND: The Activity in GEriatric acute CARe (AGECAR) is a randomised control trial to assess the effectiveness of an intrahospital strength and walk program during short hospital stays for improving functional capacity of patients aged 75 years or older. METHODS/DESIGN: Patients aged 75 years or older admitted for a short hospital stay (≤ 14 days) will be randomly assigned to either a usual care (control) group or an intervention (training) group. Participants allocated in the usual care group will receive normal hospital care and participants allocated in the intervention group will perform multiple sessions per day of lower limb strength training (standing from a seated position) and walking (10 min bouts) while hospitalized. The primary outcome to be assessed pre and post of the hospital stay will be functional capacity, using the Short Physical Performance Battery (SPPB), and time to walk 10 meters. Besides length of hospitalization, the secondary outcomes that will also be assessed at hospital admission and discharge will be pulmonary ventilation (forced expiratory volume in one second, FEV1) and peripheral oxygen saturation. The secondary outcomes that will be assessed by telephone interview three months after discharge will be mortality, number of falls since discharge, and ability to cope with activities of daily living (ADLs, using the Katz ADL score and Barthel ADL index). DISCUSSION: Results will help to better understand the potential of regular physical activity during a short hospital stay for improving functional capacity in old patients. The increase in life expectancy has resulted in a large segment of the population being over 75 years of age and an increase in hospitalization of this same age group. This calls attention to health care systems and public health policymakers to focus on promoting methods to improve the functional capacity of this population. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT01374893.

RESUMO

Background: The literature pays low attention to functional changes during acute illness in older patients. Our main objectives were to separately describe the different functional changes occurring before and after hospital admission in oldest old medical patients, to investigate their association with mortality, and identify predictors associated with in-hospital failure to recover function. Methods: Secondary analysis of data from a prospective cohort study conducted in a tertiary teaching hospital. The study followed the STROBE criteria. The sample included 604 consecutive patients aged 65 or older hospitalized for acute illness, discharged alive, and not fully dependent at baseline. Activities of daily living measured at baseline, admission, and discharge were used to classify patients into four functional trajectories depending on whether they decline or remain stable between baseline and admission (prehospital) and whether they decline, remain stable, or recover baseline function between admission and discharge (in-hospital). Multivariate models were used to test the association between functional trajectories with mortality, and predictors for in-hospital recovery. Results: Functional trajectories were: "stable-stable" (18%); "decline-recovery" (18%); "decline-no recovery" (53%); "in-hospital decline" (11%). Prehospital decline occurred in 75% and 64% were discharged with worse function than baseline. "In-hospital decline" and "decline-no recovery" trajectories were independently associated with higher 6- and 12-month mortality. Extent of prehospital decline and dementia were predictors of failure to in-hospital recovery. Conclusion: In acutely ill older people, differentiating between prehospital and in-hospital functional changes has prognostic implications. Lack of functional regain at discharge is associated with higher mortality at 6- and 12-months.

RESUMO

OBJECTIVES: To assess if the impact of oral nutritional supplements (ONS) on nutritional and functional status in malnourished older persons living in nursing homes shown by clinical trials are also found outside a trial setting. DESIGN: Observational, multicenter, prospective, pragmatic study. SETTING AND PARTICIPANTS: This study was carried out in 38 nursing homes throughout Spain. Nursing home physicians recruited consecutive residents, older than 65 years, with a diagnosis of malnutrition, when a clinical decision to start ONS had been taken after unsuccessful initial management with dietary interventions. INTERVENTION: The participants received daily 2 bottles of an energy-rich, high-protein commercial ONS for 3 months. MEASURES: Primary outcomes were changes in nutritional status [body weight, body mass index (BMI), and Mini Nutritional Assessment-Short Form (MNA-SF)]; secondary outcomes were functional changes [Functional Ambulation Classification, Barthel index, handgrip strength, and Short Physical Performance Battery (SPPB)], as well as safety and adherence after 12 weeks of follow-up. RESULTS: A total of 282 residents (median age 86 years, 67% women) were included, and 244 (86.5%) completed the follow-up. At baseline, 77.3% of the participants were malnourished (BMI 19.7 kg/m2, interquartile range 18.3-21.8). After 12 weeks of follow-up, participants experienced significant increases in body weight (2.6 ± 3.1 kg, 5.2 ± 5.9%), BMI (1.0 ± 1.2 kg/m2) and MNA-SF (4.0 ± 2.5 points). There were also significant improvements in functional status measured by the Barthel index, handgrip strength, SPPB, and gait speed. Good adherence was registered in 94.6% of the participants. No relevant side effects were found. CONCLUSIONS AND IMPLICATIONS: Improvements in nutritional and functional status can be found when using a high-protein, high-calorie ONS in older undernourished people living in nursing homes.

RESUMO

BACKGROUND: Acute hospitalisation can have adverse effects in older adults, notably functional decline. We aimed to summarize evidence on the effects of exercise interventions in acutely hospitalised older adults. METHODS: Relevant articles were systematically searched (PubMed, Web of Science, Rehabilitation & Sports Medicine Source, and EMBASE) until 19th March 2020. Randomized controlled trials (RCTs) of in-hospital exercise interventions versus usual care conducted in older adults (>60yrs) hospitalised for an acute medical condition were included. Methodological quality of the studies was assessed with the PEDro scale. Primary outcomes included functional independence and physical performance. Intervention effects were also assessed for other major outcomes (length of hospital stay, incidence of readmission, and mortality). A meta-analysis was conducted when ≥3 studies analysed the same outcome. RESULTS: Fifteen studies from 12 RCTs (n = 1748) were included. Methodological quality of the studies was overall high. None of the studies reported any adverse event related to the intervention. Exercise interventions improved functional independence at discharge (standardized mean difference [SMD] = 0.64, 95% confidence interval = 0.19-1.08) and 1-3 months post-discharge (SMD = 0.29, 95%CI = 0.13-0.43), as well as physical performance (SMD = 0.57, 95%CI = 0.18-0.95). No between-group differences were found for length of hospital stay or risk of readmission or mortality (all p > 0.05). CONCLUSIONS: In-hospital supervised exercise interventions seem overall safe and effective for improving - or attenuating the decline of - functional independence and physical performance in acutely hospitalised older adults. The clinical relevance of these findings remains to be confirmed in future research.

RESUMO

BACKGROUND: The Health Enhancing Strength Training in Nonagenarians (STRONG) is a randomised control trial to assess the effectiveness of an aerobic and strength training program for improving muscle strength, functional capacity and quality of life in nonagenarians. METHODS: Sixty (51 women) nonagenarians (age range: 90-102 years) who live in a geriatric nursing home will be randomly assigned to either a usual care (control) group (n = 30) or an intervention (training) group (n = 30). Participants allocated in the usual care group will receive general physical activity guidelines and participants allocated in the intervention group will also enroll in three weekly non-consecutive individualized training sessions (approximately 45-50 min each) during 8 weeks. The exercise program will consist of muscular strength [with a special focus on leg press at 30% (start of the program) to 70% 1 repetition maximum (end)] and aerobic exercises (cycle-ergometry during 3-5 to 15 minutes at 12-14 points in the rate of perceived exertion scale). RESULTS: Results from STRONG will help to better understand the potential of regular physical activity for improving the well-being of the oldest population groups. CONCLUSION: The increase in life expectancy together with the dramatic decrease in birth rates in industrialized countries calls the attention to health care systems and public health policymakers to focus attention on promoting healthy lifestyle in the highest sector of the population pyramid. Our study attempts to improve functional capacity and QOL of nonagenarians by implementing an individualised aerobic and strength training program in a geriatric residential care. Results from STRONG will help to better understand the potential of regular physical activity for improving the well being even in persons aged 90 years or over.

RESUMO

Societies are progressively aging, with the oldest old (i.e., those aged >80-85 years) being the most rapidly expanding population segment. However, advanced aging comes at a price, as it is associated with an increased incidence of the so-called age-related conditions, including a greater risk for loss of functional independence. How to combat sarcopenia, frailty, and overall intrinsic capacity decline in the elderly is a major challenge for modern medicine, and exercise appears to be a potential solution. In this article, we first summarize the physiological mechanisms underlying the age-related deterioration in intrinsic capacity, particularly regarding those phenotypes related to functional decline. The main methods available for the physical assessment of the oldest old are then described, and finally the multisystem benefits that exercise (or "exercise mimetics" in those situations in which volitional exercise is not feasible) can provide to this population segment are reviewed. In summary, lifetime physical exercise can help to attenuate the loss of many of the properties affected by aging, especially when the latter is accompanied by an inactive lifestyle and benefits can also be obtained in frail individuals who start exercising at an advanced age. Multicomponent programs combining mainly aerobic and resistance training should be included in the oldest old, particularly during disuse situations such as hospitalization. However, evidence is still needed to support the effectiveness of passive physical strategies including neuromuscular electrical stimulation or vibration for the prevention of disuse-induced negative adaptations in those oldest old people who are unable to do physical exercise. © 2019 American Physiological Society.

RESUMO

AIM: To evaluate the abilities to perform essential tasks for heart failure (HF) self-management in elderly patients, and its influence on post-discharge prognosis. METHODS AND RESULTS: Overall, 415 patients ≥70 years old hospitalized for HF were included and followed during 1 year. The ability to perform six specific tasks (use of a scale, weight registration, diuretic identification, knowledge of salted foods, oedema identification, and treatment adjustment) was tested and distributed on terciles (T) of performance. Correlation with the self-administered questionnaire European HF Self-care Behaviour Scale (EHFScBS) was evaluated. The independent influence of self-care on 1-year mortality and readmission risks was calculated by Cox proportional hazards regression analysis. Mean age was 80.1 years. On average, patients could perform 2.9 ± 1.6 of self-care tasks, and only 5.3% could perform the six tasks correctly. Patients with previous HF self-care education had slight better performance (3.2 ± 1.6 vs 2.8 ± 1.6, P < 0.02). A weak correlation was found between EHFScBS and number of tasks correctly performed (r = -0.135; P = 0.006). One-year mortality in T1, T2, and T3 patients was 33.0%, 20.7%, and 14.1%, respectively (P = 0.002). Multivariable analysis showed T2 and T3 groups having a lower adjusted mortality risk compared with T1 [hazard ratio (HR) 0.58; 95% confidence interval (CI) 0.32-1.03; and HR 0.40; 95% CI 0.21-0.77, respectively], without differences in readmissions. CONCLUSION: Most elderly patients admitted for HF are unable to perform several essential tasks needed for HF self-care. Self-perception of care was poorly correlated with real ability, and poor self-care ability was associated with higher 1-year mortality risk.

RESUMO

AIMS: The aim of this study was to evaluate the prevalence, clinical features, and the independent impact of frailty-a geriatric syndrome characterized by the decline of physiological systems-and its components, on prognosis after heart failure (HF) hospitalization. METHODS AND RESULTS: FRAIL-HF is a prospective cohort study including 450 non-dependent patients ≥70 years old hospitalized for HF. Frailty was screened according to the biological phenotype criteria (low physical activity, weight loss, slow walking speed, weak grip strength, and exhaustion). The independent influence of frailty on mortality, functional decline, and readmission risks was calculated adjusted for HF characteristics and co-morbidities. Mean age was 80 ± 6 years; 76% fulfilled frailty criteria. Frail patients were older, more often female, but showed no differences in chronic co-morbidities, LVEF, and NT-proBNP levels. Slow walking speed was the most discriminative component between frail (89.2%) and non-frail patients (26%). Overall, 1-year survival was 89% in the non-frail group and 75% in frail subjects (P = 0.003). After adjusting for age, gender, chronic and acute co-morbidities, NYHA, and NT-proBNP, frail patients showed higher risks for 30-day functional decline [odds ratio (OR) 2.20, 95% confidence interval (CI) 1.19-4.08], 1-year all-cause mortality [hazard ratio (HR) 2.13, 95% CI 1.07-4.23], and 1-year readmission (OR 1.96, 95% CI 1.14-3.34). The association of individual components with 1-year adjusted mortality risk was HR 2.14, 95% CI 1.05-4.39 for low physical activity and HR 1.77, 95% CI 0.95-3.29 for slow walking speed. CONCLUSION: Frailty is highly prevalent even among non-dependent elderly HF patients, and is an independent predictor of early disability, long-term mortality, and readmission. Individual frailty components may be useful for risk prediction.

RESUMO

BACKGROUND: Physical inactivity and excess adiposity are thought to be interdependent "lifestyle" factors and thus, many older adults are at exaggerated risk for preventable diseases. The purposes of this study were to determine the degree of discordance between body mass index (BMI) and adiposity among adults older than 50 years, and to determine the extent to which direct measures of adiposity, and objectively measured sedentary behavior (SB) and physical activity (PA) are associated with insulin resistance (IR) or diabetes. METHODS: A population representative sample of 2,816 individuals, aged 50-85 years, was included from the combined 2003-2006 National Health and Nutrition Examination Survey (NHANES) datasets. BMI, percent body fat (%BF) and android adiposity as determined by dual energy x-ray absorptiometry, objectively measured SB and PA, established markers of cardiometabolic risk, IR, and type 2 diabetes were analyzed. RESULTS: Approximately 50% of the men and 64% of the women who were normal weight according to BMI had excessive %BF. Adults with the least SB and greatest moderate and vigorous PA exhibited the healthiest cardiometabolic profiles, whereas adults with the greatest SB and lowest activity had highest risk. Greater android adiposity stores were robustly associated with IR or diabetes in all adults, independent of SB and activity. Among men, less moderate-to-vigorous PA was associated with IR or diabetes; whereas among women, less lifestyle moderate activity was associated with IR or diabetes. CONCLUSIONS: Android adiposity and low moderate and vigorous PA are the strongest predictors of IR or diabetes among aging adults.

RESUMO

The clinical scenario of heart failure (HF) in older hospitalized patients is complex and influenced by acute and chronic comorbidities, coexistent geriatric syndromes, the patient's ability for self-care after discharge, and degree of social support. The impact of all these factors on clinical outcomes or disability evolution is not sufficiently known. FRAIL-HF is a prospective observational cohort study designed to evaluate clinical outcomes (mortality and readmission), functional evolution, quality of life, and use of social resources at 1, 3, 6, and 12 months after admission in nondependent elderly patients hospitalized for HF. Clinical features, medical treatment, self-care ability, and health literacy were prospectively evaluated and a comprehensive geriatric assessment with special focus on frailty was systematically performed in hospital to assess interactions and relationships with postdischarge outcomes. Between May 2009 and May 2011, 450 consecutive patients with a mean age of 80 ± 6 years were enrolled. Comorbidity was high (mean Charlson index, 3.4 ± 2.9). Despite being nondependent, 118 (26%) had minor disability for basic activities of daily living, only 76 (16.2%) had no difficulty in walking 400 meters, and 340 (75.5%) were living alone or with another elderly person. In addition, 316 patients (70.2%) fulfilled frailty criteria. Even nondependent older patients hospitalized for HF show a high prevalence of clinical and nonclinical factors that may influence prognosis and are usually not considered in routine clinical practice. The results of FRAIL-HF will provide important information about the relationship between these factors and different postdischarge clinical, functional, and quality-of-life outcomes.

RESUMO

BACKGROUND: The main objective of this study was to analyze the independent effect of increasing age on the recovery of different areas of functioning 1 year after hip fracture. METHODS: Consecutive 1-year survivors aged ≥ 65 years (n = 362) admitted to a single hospital for acute hip fracture surgery were followed prospectively for 1 year. Age was stratified as <75, 75-84, and ≥ 85 years. Basic activities of daily living and ambulation were measured by personal interview during hospitalization and phone contact at 3, 6, and 12 months. Longitudinal data of recovery in these areas were analyzed using generalized estimating equations. RESULTS: Older age was strongly associated with poor recovery in all areas of function, except eating. The pattern of recovery of ambulation differed with age, peaking at 6 months in the younger group and continuing for at least 12 months in the eldest group. The pattern of recovery of overall and individual activities of daily living was similar in the three age groups. Recovery of areas associated with upper extremity function peaked at 3 months, whereas areas associated with lower extremity function peaked at 6 months. CONCLUSIONS: The patterns of functional disability after hip fracture differ with areas of function and age with the oldest patients having a particular risk of decline and a prolonged time to recovery of ambulation.

RESUMO

OBJECTIVE: To assess the most appropriate criteria considered by geriatricians to select patients who might benefit the most from geriatric hospital care. MATERIAL AND METHODS: We carried out a survey that consisted of various socio-demographic, clinical, functional and mental criteria included in the definition of the geriatric and frail elderly patient. The survey was sent to all specialists in geriatrics in the different hospitals of the Madrid Health Service. They were asked to answer to each criterion indicating whether they considered it as high priority, priority, low priority or no priority. The responses were clustered by type of hospital: acute hospitals with or without a post-graduate geriatric program for medical residents, and medium and long stay hospitals. RESULTS: A total of 83 questionnaires were completed (70% of the study population): 42 teaching hospitals a post-graduate geriatric program (74% of possible), 20 of those with an emergency department but without a post-graduate geriatric program (56% of possible), and 21 medium and long stay hospitals (84% of potential). All proposed criteria were considered individually as priority or high-priority by more than 50% of respondents. An age 85 years and over, admission for hip fracture, the presence of severe cognitive or functional impairment, frailty, and unexplained deterioration of health status, were considered individually as criteria for selecting high-priority target population by more than 85% of respondents. CONCLUSIONS: Certain criteria, such as advanced age, or the presence of geriatrics-specific conditions, such as hip fracture or severe functional or cognitive impairment, are identified by geriatricians as useful to select patients to receive geriatric specialist hospital care.

RESUMO

OBJECTIVES: To assess the effects of an 8-week exercise training program with a special focus on light- to moderate-intensity resistance exercises (30-70% of one repetition maximum, 1RM) and a subsequent 4-week training cessation period (detraining) on muscle strength and functional capacity in participants aged 90 and older. DESIGN: Randomized controlled trial performed during March to September 2009. SETTING: Geriatric nursing home. PARTICIPANTS: Forty nonagenarians (90-97) were randomly assigned to an intervention or control group (16 women and 4 men per group). INTERVENTION: Eight-week muscle strength exercise intervention focused on lower limb strength exercises of light to moderate intensity. PRIMARY OUTCOME: 1RM leg press. SECONDARY OUTCOMES: handgrip strength, 8-m walk test, 4-step stairs test, Timed Up and Go test, and number of falls. RESULTS: A significant group by time interaction effect (P=.02) was observed only for the 1RM leg press. In the intervention group, 1RM leg press increased significantly with training by 10.6 kg [95% confidence interval (CI)=4.1-17.1 kg; P=.01]. Except for the mean group number of falls, which were 1.2 falls fewer per participant in the intervention group (95% CI=0.0-3.0; P=.03), no significant training effect on the secondary outcome measures was found. CONCLUSION: Exercise training, even of short duration and light to moderate intensity, can increase muscle strength while decreasing fall risk in nonagenarians.
