Potential protein biomarkers in saliva for detection of frailty syndrome by targeted proteomics

Frailty is a physiological geriatric syndrome, caused by immunosenescence, inflammation and alterations at the protein level leading to metabolic and microbiota changes. Currently, this syndrome is evaluated clinically with the Frailty-VIG index. The aim of the study was therefore to investigate the potential suitability of saliva as a non-invasive proximal biological fluid for the characterisation and identification of possible protein-level biomarkers in frailty syndrome. This cross-sectional study was conducted in a rural population of older Spanish adults using the SMR proteomics technique. A differential protein profile of eight potential and surrogate proteins (CYTC, CYTD, CYTS, CYTB, MIF, ALBU, CD44 and B2MG) was detected in saliva, all of which correlated with factors characterising frailty syndrome, such as vascular ageing (arterial stiffness and cardiovascular disease), obesity, mood problems, global cognitive impairment, changes in gait and hand pressure strength. The proteins CYTD (r = 0.415, p = 0.013) and CYTC (r = 0.280, p = 0.026), which were detected differentially in the protein profile, were associated with the Frailty-VIG index. All analysed proteins are associated not only with the clinical symptoms of frailty syndrome, but also with an acute inflammatory response, endothelial cell proliferation and the complement system, among others.

Taiwanese reference values for the Short Physical Performance Battery in community-dwelling older adults

OBJECTIVES

To establish reference values for SPPB score as well as test performances among Taiwanese community-dwelling older adults.

METHODS

Participants included 847 older adults. The total scores and three subtest scores for the SPPB and the registered time to complete the walk and five-repetition sit-to-stand (STS) tests were determined and compared between sex and age (65-74, 75-84, and ≥85 years) groups.

RESULTS

The mean SPPB total score was 10.9 in women and 10.5 in men. SPPB scores did not differ by sex, regardless of age group. However, the walk test (p = .030) and STS test (p = .008) timings were longer for men than for women in the 65-74-year-old group. The ≥85-year-old men achieved a lower balance score than did the 65-74-year-old men (p = .027).

CONCLUSIONS

Population-specific SPPB reference values contribute to assessments of physical function and facilitate cross-cultural comparisons of physical performance.

Reliability and minimal detectable change of the Short Physical Performance Battery in older adults with mild cognitive impairment

OBJECTIVES

Reliability of the Short Physical Performance Battery (SPPB) are rarely examined among older adults with mild cognitive impairment (MCI). This study aimed to investigate the test-retest reliability and minimal detectable change (MDC) of the SPPB in older adults with MCI.

METHODS

Participants included 100 older adults with MCI. The SPPB was assessed with the first 2 assessments separated by a 20-min interval and the third separated by a 1-week interval. The intraclass correlation coefficient (ICC) and MDC values were estimated.

RESULTS

The intraday ICC was 0.73 for the SPPB score, 0.90 for the 4-m walk time (4mwt), and 0.95 for the 5-times chair stand time (5cst); the corresponding interday ICC values were 0.76, 0.89, and 0.91, respectively. The MDC values ranged from 1.1 to 1.2 for the SPPB score, from 0.77 to 0.80 s for the 4mwt, and from 1.32 to 1.77 for the 5cst.

CONCLUSIONS

The SPPB had satisfactory reliability among older adults with MCI. The test-retest reliability of the SPPB is sufficient (>0.7) for group comparisons. Moreover, the test-retest reliability for the 4mwt and 5cst subscale performances is acceptable (> 0.9) for individual-level measurements over time.

Functionality, muscular strength and cardiorespiratory capacity in the elderly: relationships between functional and physical tests according to sex and age

Introduction: There are several tests that provide information about physical fitness and functionality in older adults. The aims of this study were: (i) to analyze the differences between sex and age in functional, strength and cardiorespiratory tests; and (ii) to study the correlations between functional, strength and cardiorespiratory tests according to sex and age. Methods: A total of 171 older adults (72.09 ± 13.27 kg; 1.59 ± 0.09 m; 72.72 ± 6.05 years) were divided according to sex (men: n = 63; women: n = 108) and age (≥60 <70: n = 65; ≥70 <80: n = 89; ≥80: n = 18). Anthropometry, body composition, upper limb strength (hand grip; HG), lower limb strength (countermovement jump; CMJ), cardiorespiratory capacity (6 min walking test; 6MWT), timed up and go test (TUG) and Short Physical Performance Battery (SPPB) were assessed. Results: Men showed higher values in CMJ height, HG and expired volume (VE) (p < 0.05). There were no significant differences between sexes in TUG and SPPB. Regarding age, there were significant differences in CMJ, VE and peak oxygen uptake (VO2peak), TUG, gait speed, chair and stand test and SPPB total (p < 0.05). The test times were higher in older people. Regarding correlations, the TUG showed significant correlations in all strength and cardiorespiratory tests, regardless of sex and age. The CMJ correlated more significantly with functional tests compared to HG. Discussion: There were sex and age differences in functional, strength, and cardiorespiratory tests. The execution of quick and low-cost tests such as the CMJ and TUG could provide information on overall physical fitness in older adults.

Effectiveness of a cardiac rehabilitation program on biomechanical, imaging, and physiological biomarkers in elderly patients with heart failure with preserved ejection fraction (HFpEF): FUNNEL + study protocol

BACKGROUND

Patients with heart failure with preserved ejection fraction (HFpEF) have a low functional status, which in turn is a risk factor for hospital admission and an important predictor of survival in HFpEF. HFpFE is a heterogeneous syndrome and recent studies have suggested an important role for careful, pathophysiological-based phenotyping to improve patient characterization. Cardiac rehabilitation has proven to be a useful tool in the framework of secondary prevention in patients with HFpEF. Facilitating decision-making and implementing cardiac rehabilitation programs is a challenge in public health systems for HFpEF management. The FUNNEL + study proposes to evaluate the efficacy of an exercise and education-based cardiac rehabilitation program on biomechanical, physiological, and imaging biomarkers in patients with HFpEF.

METHODS

A randomised crossover clinical trial is presented among people older than 70 years with a diagnosis of HFpEF. The experimental group will receive a cardiac rehabilitation intervention for 12 weeks. Participants in the control group will receive one educational session per week for 12 weeks on HFpEF complications, functional decline, and healthy lifestyle habits. VO2peak is the primary outcome. Biomechanical, imaging and physiological biomarkers will be assessed as secondary outcomes. Outcomes will be assessed at baseline, 12 weeks, and 24 weeks.

DISCUSSION

Identifying objective functional parameters indicative of HFpEF and the subsequent development of functional level stratification based on functional impairment ("biomechanical phenotypes") may help clinicians identify cardiac rehabilitation responders and non-responders and make future clinical decisions. In this way, future pharmacological and non-pharmacological interventions, such as exercise, could be improved and tailored to improve quality of life and prognosis and reducing patients' hospital readmissions, thereby reducing healthcare costs.

Effects of COVID-19 Lockdown on Nutritional, Functional and Frailty Biomarkers of People Living in Nursing Homes. A Prospective Study

BACKGROUND

Nursing home residences suffered a lockdown from the beginning of the COVID-19 pandemic. The present study prospectively evaluates the frailty, functional, and nutritional statuses of nursing home residents.

METHODS

Three hundred and one residents from three nursing homes took part in the study. Frailty status was measured using the FRAIL scale. Functional status was evaluated using the Barthel Index. Additionally, Short Physical Performance Batter (SPPB), SARC-F, hand-grip strength, and gait speed were also evaluated. Nutritional status was determined using the mini nutritional assessment test (MNA) and several anthropometrical and biochemical markers.

RESULTS

Mini Nutritional Assessment test scores decreased in 20% throughout the confinement (p < .001). Barthel index, SPPB and SARC-F scores also decreased, although to a lesser extent, reflecting a decrease in functional capacity. However, both anthropometric parameters, hand grip strength and gait speed, remained stable throughout confinement (p > .050 in all cases). Morning cortisol secretion significantly decreased by 40% from baseline to post-confinement. A significant reduction in daily cortisol variability was observed, which may suggest increased distress. Fifty-six residents died during the period of confinement (81.4% survival rate). Sex, FRAIL and Barthel Index scores were significant predictors of resident survival.

CONCLUSION

After the first COVID-19 blockade, several alterations in residents' frailty markers were observed, which were small and potentially reversible. However, many of the residents were pre-frail after the lockdown. This fact highlights the need for preventive strategies to reduce the impact of future social and physical stressors on these vulnerable individuals.

Validity and Reliability of the Short Physical Performance Battery Tool in Institutionalized Spanish Older Adults

BACKGROUND

In order to be used safely, accurately and reliably, measuring instruments in the health field must first be validated, for which the study of their psychometric properties is necessary. The Short Physical Performance Battery (SPPB) tool is a widely used clinical assessment test that has been approved for usage across several nations, languages and demographics. Finding SPPB's psychometric properties for a sample of institutionalized older individuals is the aim of this research.

METHODS

This is a multicenter, retrospective and observational study of the psychometric properties of the Short Physical Performance Battery tool with a convenience sample of 194 institutionalized older adults. Reliability (internal consistency) and validity (construct validity and convergent validity) tests were performed.

RESULTS

The results show a very good internal consistency, construct validity and convergent validity. In addition, the factorial structure of the SPPB is provided, which reflects that it is a unidimensional scale.

CONCLUSIONS

In conclusion, the Short Physical Performance Battery is a valid and reliable tool for use with institutionalized older adults. Its use is recommended as part of the Comprehensive Geriatric Assessment for the evaluation of the physical or functional sphere. This study was not registered.

Cognitive and functional trajectories in geriatric outpatients after a pharmacologic multidisciplinary intervention: A study protocol

BACKGROUND

Polypharmacy is a common condition among older adults and is associated with adverse drug reactions and health outcomes, including falls, functional and cognitive impairment, and frailty.

METHODS

A prospective observational study will be conducted on older adults with polypharmacy. The aim is to assess the impact of a specialized outpatient clinic focused on pharmacotherapy optimization recently integrated into daily clinical practice in a Spanish public tertiary teaching hospital on patients' functional and cognitive abilities. Patients who attend a first consultation and meet inclusion criteria (≥75 years old, have a life expectancy≥3 months, and polypharmacy (≥5 prescribed medications) will be invited to participate in the study, until reach a calculated sample size of 104 participants. Patients will be excluded if they are enrolled in a clinical trial related to medication or in the event of a no-show or cancellation of the appointment at the first visit. Participants will receive usual care: a first consultation including multidisciplinary pharmacological optimization in the context of a CGA and subsequent face-to-face and/or telephone follow-up (∼3 and ∼6 months). The primary endpoint will be the functional (Barthel index) and cognitive change in capacities (IPCR - Índice de Incapacidad psíquica de la Cruz Roja). Secondary endpoints include medication changes, changes in patients' quality of life, rate of falling, and use of healthcare resources.

DISCUSSION

We expect that the close collaboration between professionals from different disciplines working together will be an effective strategy to improve the functional and cognitive abilities of older adults.

Risk factors for developing symptomatic COVID-19 in older residents of nursing homes: A hypothesis-generating observational study

Objectives

To identify which risk factors were associated with developing Coronavirus Disease-19 (COVID-19) infection, with symptoms, in institutionalized older people.

Methods

A 1-year longitudinal multi-center study was conducted in 5 nursing homes (NHs) over the period December 2019 to March 2021. Inclusion criteria included being a permanent resident in the NH, aged 65 years or older, and a positive diagnosis of COVID-19 objectively confirmed by a diagnostic test. A descriptive and bivariate analysis was performed, calculating relative risk (RR) with 95% confidence intervals and statistical significance at p<0.05.

Results

Of the total sample of 78 individuals who tested positive for COVID-19, the mean age was 84.6 years (SD=±7.8), 62 (79.5%) were female; 40 (51.3%) participants presented with COVID-19 symptoms. Living in a private NH (RR=3.6, 95% CI [1.2-11.0], p=0.023) and having suffered a stroke (RR=4.1, 95% CI [1.1-14.7], p=0.033) were positively associated with developing COVID-19 infection with symptoms.

Conclusions

Having suffered a stroke and living permanently in a private NH were positively associated with symptomatic COVID-19 in this sample of institutionalized older people.Clinical Trials ID: NCT04297904.

Living Conditions and the Incidence and Risk of Falls in Community-Dwelling Older Adults: A Multifactorial Study

Old age represents a social group that is undergoing continuous expansion. The aging population will be prone to chronic diseases and falls, which is a marker of frailty and a public health problem. This study aims to examine the relationship between living conditions and the prevalence of the risk of falls in older adults within the community. As an observational cross-sectional study, intentional sampling was carried out on residents of the metropolitan area over 75 years of age. The socio-demographic data of the subjects and their history of falls were collected. Additionally, the subjects were evaluated on the risk of falling, basic activities of daily living, such as walking and balance, fragility, and their fear of falling. The statistical analyses used were based on the Shapiro-Wilk test for normality, statistics of central tendency with description, mean (M) and dispersion, standard deviation (SD), bivariate contingency tables for studying the relationships between the variables, and the analysis of Pearson's relational statistics (χ²). The comparisons of means were resolved by parametric or non-parametric routes. We obtained the following results: 1. The socio-demographic profile of our sample consisted of adults over 75 years of age, the majority of whom were overweight or obese women living in an urban area, specifically in an apartment, and receiving care; 2. Older people in the studied community had mild dependency and frailty, and were also at severe risk of falls; 3. The prevalence of falls was higher in women than in men in this study. Through these results, we confirmed the relationship between living conditions and the prevalence of risk of falls in older adults within the community.

SMARTfit Dual-Task Exercise Improves Cognition and Physical Function in Older Adults With Mild Cognitive Impairment: Results of a Community-Based Pilot Study

Mild cognitive impairment is an intermediate state between the cognitive decline often experienced in normal aging and dementia that affects 15% of Americans over 65 years of age. Our communities have an opportunity to support the development and adoption of evidence-based programs to help older adults preserve cognition and physical function. In partnership with a local urban YMCA in an underserved, predominantly minority neighborhood, we tested the appeal and therapeutic benefits of SMARTfit training among older adults with mild cognitive impairment. The participants reported a positive training experience. After 12 weeks of dual-task training, Trail-Making Test and Stroop Color-Word Interference Test scores improved, as did scores on the Short Physical Performance Battery. Results of our SMARTfit dual-task training intervention are encouraging. Larger randomized controlled trials must further investigate the development, implementation, and therapeutic impacts of SMARTfit dual-task training on cognitive and physical function in aging.

A group-based exercise and behavioural maintenance intervention for adults over 65 years with mobility limitations: the REACT RCT

Background

Mobility limitation in older age reduces quality of life, generates substantial health- and social-care costs, and increases mortality.

Objective

The REtirement in ACTion (REACT) trial aimed to establish whether or not a community-based active ageing intervention could prevent decline in physical functioning in older adults already at increased risk of mobility limitation.

Design

A multicentre, pragmatic, two-arm, parallel-group randomised controlled trial with parallel process and health economic evaluations.

Setting

Urban and semi-rural locations across three sites in England.

Participants

Physically frail or pre-frail older adults (aged ≥ 65 years; Short Physical Performance Battery score of 4–9). Recruitment was primarily via 35 primary care practices.

Interventions

Participants were randomly assigned to receive brief advice (three healthy ageing education sessions) or a 12-month, group-based, multimodal exercise and behavioural maintenance programme delivered in fitness and community centres. Randomisation was stratified by site and used a minimisation algorithm to balance age, sex and Short Physical Performance Battery score. Data collection and analyses were blinded.

Main outcome measures

The primary outcome was change in lower limb physical function (Short Physical Performance Battery score) at 24 months, analysed using an intention-to-treat analysis. The economic evaluation adopted the NHS and Personal Social Services perspective.

Results

Between June 2016 and October 2017, 777 participants (mean age 77.6 years, standard deviation 6.8 years; 66% female; mean Short Physical Performance Battery score 7.37, standard deviation 1.56) were randomised to the intervention arm (n = 410) or the control arm (n = 367). Data collection was completed in October 2019. Primary outcome data at 24 months were provided by 628 (80.8%) participants. At the 24-month follow-up, the Short Physical Performance Battery score was significantly greater in the intervention arm (mean 8.08, standard deviation 2.87) than in the control arm (mean 7.59, standard deviation 2.61), with an adjusted mean difference of 0.49 (95% confidence interval 0.06 to 0.92). The difference in lower limb function between intervention and control participants was clinically meaningful at both 12 and 24 months. Self-reported physical activity significantly increased in the intervention arm compared with the control arm, but this change was not observed in device-based physical activity data collected during the trial. One adverse event was related to the intervention. Attrition rates were low (19% at 24 months) and adherence was high. Engagement with the REACT intervention was associated with positive changes in exercise competence, relatedness and enjoyment and perceived physical, social and mental well-being benefits. The intervention plus usual care was cost-effective compared with care alone over the 2 years of REACT; the price year was 2019. In the base-case scenario, the intervention saved £103 per participant, with a quality-adjusted life-year gain of 0.04 (95% confidence interval 0.006 to 0.074) within the 2-year trial window. Lifetime horizon modelling estimated that further cost savings and quality-adjusted life-year gains were accrued up to 15 years post randomisation.

Conclusion

A relatively low-resource, 1-year multimodal exercise and behavioural maintenance intervention can help older adults to retain physical functioning over a 24-month period. The results indicate that the well-established trajectory of declining physical functioning in older age is modifiable.

Limitations

Participants were not blinded to study arm allocation. However, the primary outcome was independently assessed by blinded data collectors. The secondary outcome analyses were exploratory, with no adjustment for multiple testing, and should be interpreted accordingly.

Future work

Following refinements guided by the process evaluation findings, the REACT intervention is suitable for large-scale implementation. Further research will optimise implementation of REACT at scale.

Sarcopenia and associated factors according to the EWGSOP2 criteria in older people living in nursing homes: a cross-sectional study

Background

In 2018, the European Working Group on Sarcopenia in Older People (EWGSOP2) updated the original definition of sarcopenia, establishing new criteria to be used globally. Early diagnosis of sarcopenia in nursing home residents and the identification of contributing factors would target interventions to reduce the incidence of malnutrition, social isolation, functional decline, hospitalization and mortality.

Aim

Verify the prevalence and the degree of severity of sarcopenia according to the new EWSGOP2 criteria and to analyse its associated factors in residents living in nursing homes in Central Catalonia (Spain).

Design

A cross-sectional multicenter study was conducted in 4 nursing homes. SARC-F test was applied as the initial screening, muscle strength was measured by a dynamometer, skeletal muscle mass by bioimpedance analysis and physical performance by Gait Speed. Four categories were used: total probable sarcopenia, probable sarcopenia, confirmed sarcopenia and severe sarcopenia.

Results

Among the total sample of 104 nursing home residents (mean age 84.6, ± 7.8; median 86, IQR 110), 84.6% were women and 85 (81.7%) (95% confidence interval [CI] 73.0-88.0) had total probable sarcopenia, 63 (60.5%) had probable sarcopenia, 19 (18.3%) had confirmed sarcopenia and 7 (6.7%) had severe sarcopenia. In the bivariate analysis, obesity was negatively associated and total time in sedentary behavior positively associated with all sarcopenia categories. In addition, malnutrition and urinary continence were positively associated with total and probable sarcopenia. Urinary incontinence was a positive associated factor of total and probable sarcopenia. In the multivariate analysis, obesity represented a negative associated factor: OR = 0.13 (0.03 - 0.57), p = 0.007 and OR = 0.14 (0.03 - 0.60), p = 0.008 with total and probable sarcopenia, respectively, adjusted by urinary incontinence status. For confirmed sarcopenia, obesity also represented a negative associated factor OR = 0.06 (0.01 - 0.99), p = 0.049 and the total time in sedentary behavior a positive associated factor OR = 1.10 (1.00- 1.20), p = 0.040.

Conclusions

According the EWGSOP2 criteria, high prevalence of sarcopenia was found in institutionalized older people, ranging from 6.7 to 81.7% depending on the category. Malnutrition, urinary incontinence and total time in sedentary behavior were associated with sarcopenia, whilst obesity represented a protective factor in this population.

Physical Performance, Cardiovascular Health and Psychosocial Wellbeing in Older Adults Compared to Oldest-Old Residential Seniors

Background: This study analyzed physical, cardiovascular, and psychosocial health in different age groups at the far end of the lifespan. Methods: Sixty-two residential seniors participated in this cross-sectional study and were assigned according to age to either the older adults (n = 27; age: 74.8 (3.6); f: 23) or the oldest-old group (n = 35; age: 87.2 (5.0); f: 28). Gait speed, functional mobility, handgrip strength, and pulse wave velocity (PWV) were measured. Additionally, questionnaires to assess quality of life were applied. Mean between-group differences (Δ) and Hedge’s g with 95 % confidence intervals were calculated. Results: Oldest-old had moderately lower handgrip strength (Δ = −31.3 N, 95% CI [−66.30; −1.65], Hedge’s g = 0.49 [−0.97; 0.03]) and relevant lower gait speed than the older adults (Δ = −0.11 m/s [−0.28; 0.05], g = 0.34 [−0.89; 0.20]). All other physical parameters showed trivial differences. Very large effects were found in PWV in favor of the older adults (Δ = −2.65 m/s [−3.26; −2.04], g = −2.14 [−2.81; −1.36]). The questionnaires showed trivial to small differences. Conclusion: We found small differences in physical as well as psychosocial health between age groups with large inter-individual variance. Large differences were found in arterial stiffness, which increases with age. Exercise programs in nursing homes should consider physical, psychosocial, and cardiovascular variables more than age.

The effect that the Otago Exercise Programme had on fear of falling in community dwellers aged 65-80 and associated factors

BACKGROUND

Falls are a major public health problem. Fear of falling is highly prevalent amongst community-dwelling older adults who have already fallen and it is also a risk factor for recurrent falls. There has been limited research about the impact that exercises programs have on the fear of falling. The aim of this study was to evaluate whether the Otago Exercise Programme (OEP) reduced the fear of falling in non-institutionalised people aged 65-80 years in Spain. It also evaluated the factors associated with the fear of falling.

METHODS

This was a quasi-experimental study that focused on people aged 65-80 who attended 21 primary healthcare centres, lived in the community, were able to walk independently and provided written, informed consent. They were recruited from September 2017 to December 2019. The OEP sessions took place at the primary healthcare centres and were provided on an individual or group basis by trained OEP instructors. The participants attended five weekly sessions, where they were given exercises to develop their strength, balance and endurance. They then continued the programme at home. The subjects were followed up 12 months after baseline and the analyses included a bivariate analysis and a multivariate analysis with logistic regression.

RESULTS

We enroled 498 patients (67.07% female) with an average age of 71.81 years. More than two-thirds (65.06%) lived with a partner and 42.37% were overweight. Significant reductions were observed in the mean level of fear of falling between baseline and 12 months (p = 0.000). A number of factors associated with fear of falling also showed significant differences. These were: age (p = 0.033), sex (p = 0.000), living alone (p = 0.000), body mass index (p = 0.003) and whether psychotropic drugs were used (p = 0.000). The multivariate analysis showed a moderate to high fear of falling amongst participants who were female (p = 0.000), 72-80 years of age (p = 0.017), obese (p = 0.045) and used psychotropic drugs (p = 0.021).

CONCLUSIONS

Taking part in the OEP reduced the overall fear of falling. There were significant associations between fear of falling and being female, taking psychotic drugs and having a history of falls. This study is a quasi-experimental sign nested an experimental study (randomized controlled trial previously published and registered on ClinicalTrials.org (NCT03320668)). Retrospectively registered on 25/10/2017.

2015-2016 Normative Data for the 3-m Usual Walk, Five Repeated Chair Stands, and Static Balance Components of the SPPB Among U.S. Older Adults Across Two Nationally Representative Data Sets: NSHAP and NHATS

OBJECTIVES

Our primary objective was to examine the distribution of 3-m usual walk, five repeated chair stands, and three static balance stance performances among age and gender subgroups of adults at least 65 years in two national data sets. We secondarily determined whether demographic-function associations varied across data sets, birth cohorts, or models incorporating data from those "unable to do" tasks.

METHODS

Two nationally representative data sets were used to generate survey weight-adjusted performance distributions: the 2015-2016 National Social Life Health and Aging Project and the 2016 National Health and Aging Trends Study. We then regressed walk and chair stand performance on age, gender, and race/ethnicity, examining differences across data sets, birth cohorts (1920-1947, 1948-1965), and before/after incorporating the "unable to do" performers.

RESULTS

Findings confirmed the gradual decline in function with age and allowed estimation of "relative" performance within age/gender subgroups. Data set distribution differences were noted, possibly due to recruitment, eligibility, and protocol variations. Demographic associations were similar across data sets but generally weaker among the 1948-1965 cohort and in models including the sizable "unable to do" group.

DISCUSSION

We present the largest, most current Short Physical Performance Battery reference data in U.S. adults aged 65 or older. Findings support standardization of administration protocols in research and clinical care and differentiating absolute from relative performance.

Multicomponent Staff Training Intervention to Improve Residential Dementia Care (PROCUIDA-Demencia): A Mixed-Methods 2-Arm Cluster Randomized Controlled Pilot and Clinical Outcomes Study

OBJECTIVES

To evaluate the feasibility outcomes of implementing a multicomponent staff training intervention (PROCUIDA-Demencia) to promote psychosocial interventions and reduce antipsychotic prescription in Mexican care homes and study its effect on staff's care experience and residents' quality of life.

DESIGN

A mixed-methods 2-arm cluster randomized controlled pilot study of a 2-day staff training program with baseline, 12 weeks, and 24 weeks of the PROCUIDA-Demencia intervention vs treatment as usual (TAU).

SETTING AND PARTICIPANTS

Eight care homes in Mexico City were selected, from which 55 residents and 126 staff were recruited.

INTERVENTION

In situ staff training consisting of evidence-based manualized psychosocial interventions of person-centered activities, reminiscence therapy, doll therapy, psychomotor dance therapy, and antipsychotic prescription review. Fidelity to protocol was supervised once a week.

METHODS

Cluster-level feasibility measures included views of staff, residents, and relatives on acceptability, satisfaction, adherence, and fidelity to the intervention. Staff outcome measures were Maslach Burnout Inventory (MBI), Approaches to Dementia Questionnaire, and Sense of Competence in Dementia Care Staff. Residents' outcome measures included Quality of Life-Alzheimer's Disease scale (QoL-AD), and Neuropsychiatric Inventory-Nursing Home Version (NPI-NH). Staff distress was measured using the NPI-NH occupational disturbance scale. Feasibility was elicited through a focus group, and hierarchical linear mixed effects models were used to assess the adjusted effects of the respective measures.

RESULTS

Observed medical practice showed the prescription of at least 1 antipsychotic in 41% of participants in the intervention group. Overall, 39% of residents reported discontinuation, and 15% reduction of antipsychotics, following the 12-week medical review in parallel with psychosocial interventions. Clinical outcomes contributed positively to the reduction in baseline staff burden according to the MBI after the intervention [mean difference -8.9, 95% confidence interval (CI) -17.7, -0.1, P = .049] and to the reduction in severity and frequency of behavior as per NPI-NH in residents (mean difference -9.4, 95% CI -17.5, -1.3, P = .025).

CONCLUSIONS AND IMPLICATIONS

PROCUIDA-Demencia is a feasible intervention for Mexican care homes. Results contribute to the Mexican Dementia Plan optimizing dementia care by supporting the need for staff training to implement psychosocial interventions prior to prescribing antipsychotic medication.

Nutritional status and physical performance using handgrip and SPPB tests in hospitalized older adults

BACKGROUND & AIMS

Malnutrition and poor physical performance are highly prevalent within hospitalized older adults, and both have in common the loss of muscle mass. Likewise, there is growing interest in identifying markers of physical performance, other than just measuring muscle mass, that might be useful for managing malnutrition. This study aimed to (i) characterize the physical condition of hospitalized older adults in comparison to previously published reference percentile values of same age adults and (ii) to examine the association between the nutritional status and physical performance of older inpatients.

METHODS

A total of 604 inpatients (age 84.3 ± 6.8 years, 50.3% women) participated in this cross-sectional study. Patients were assessed for nutritional status (Mini Nutritional Assessment-Short Form (MNA-SF)) and physical performance (handgrip strength and the Short Physical Performance Battery (SPPB)).

RESULTS

During hospitalization, 65.7% of the inpatients were at risk of malnutrition or malnourished. More than a half of the older inpatients were unfit (≤P25) for handgrip strength (52.0%) and SPPB total score (86.3%) as well as for two of its subtests, gait speed (86.7%) and 5 times sit-to-stand (91.1%) tests. Patients' nutritional status was significantly associated with better physical performance within all tests (all p < 0.001), as their nutritional status improved so did their physical performance (all p for trend <0.001). Hence, being at risk of malnutrition or malnourished significantly increased the likelihood for being classified as unfit according to handgrip strength (OR: 1.466, 95% CI: 1.045-2.056), SPPB total score (OR: 2.553, 95% CI: 1.592-4.094) and 4-m walking test (OR: 4.049, 95% CI: 2.469-6.640) (all p < 0.05), and as frail (OR: 4.675, 95% CI: 2.812-7.772) according to the SPPB frailty threshold (p < 0.001).

CONCLUSIONS

This study reinforces the use of handgrip strength and SPPB, as well as its subtests (gait speed and 5 times sit-to-stand tests), in hospitalized older adults as alternative measures of muscle mass for malnutrition management. Hence, it seems that risk of malnutrition or malnutrition assessed by MNA-SF might help to predict poor physical performance in older inpatients.

The Fracture Liaison Service of the Virgen Macarena University Hospital Reduces the Gap in the Management of Osteoporosis, Particularly in Men. It Meets the International Osteoporosis Foundation Quality Standards

OBJECTIVES

To describe the Fracture Liaison Service (FLS), to know the characteristics of the patients attended with emphasis on sex differences, and to know the compliance of International Osteoporosis Foundation (IOF) quality standards.

METHODS

Observational, prospective research. All the consecutive patients that attended in usual clinical practice from May 2018 to October 2019, were over 50 years, and with a fragility fracture (FF), were included.

RESULTS

Our FLS is a type A multidisciplinary unit. We included 410 patients, 80% women. FF recorded in 328 women were: Hip (132, 40%), Clinical Vertebral (81, 25%) and No hip No vertebral (115, 35%). Those in 82 men were: Hip (53, 66%), Clinical Vertebral (20, 24%) and No hip No vertebral (9, 10%), p = 0.0001. Men had more secondary osteoporosis (OP). The most remarkable result was the low percentage of patients with OP receiving treatment and the differences between sex. Forty-nine (16%) women versus nine (7%) men had received it at some point in their lives, p = 0.04. The probability of a man not receiving prior treatment was 2.5 (95%CI 1.01-6.51); p = 0.04, and after the FF was 0.64 (0.38-1.09). Treatment adherence in the first year after the FLS was 96% in both sexes. The completion of IOF quality standards was bad for patient identification and reference time. It was poor for initial OP screening standard and good for the remaining ten indicators.

CONCLUSIONS

the FLS narrowed the gap in diagnosis, treatment, and follow-up of fragility fracture patients, especially men. The FLS meets the IOF quality standards.

[Reference values for SPPB in people over 60 years of age in the Basque Country]

Objetivo

Proporcionar valores de referencia del Short Physical Performance Battery (SPPB) en adultos y adultos mayores en el País Vasco, identificando puntos de corte para medir la fragilidad y comparar los valores con otras poblaciones de España.

Emplazamiento

Bilbao capital, País Vasco (España).

Participantes

1.923 personas mayores de 60 años incluidos en el Programa de Salud para Personas Mayores del Ayuntamiento de Bilbao participaron en el estudio. El programa de actividad física (AF) se impartió dos veces por semana durante un mínimo de 12 semanas, con sesiones de 50 minutos.

Mediciones principales

Se evaluó a los participantes con la prueba SPPB que evalúa: equilibrio (PE), velocidad de la marcha en 4 m (PM) y la fuerza a través de la prueba de levantarse y sentarse de la silla (PS). Según el resultado obtenido de todas las pruebas, se identificó la funcionalidad de las personas en: limitación grave (cero a cuatro puntos), moderada (cuatro a seis puntos), leve (siete a nueve puntos) y mínima (10 a 12 puntos).

Resultados

Edad media 77,9 (5,6) años, siendo el 87,9% mujeres y el 12,1% hombres. La batería SPPB mostro diferencias significativas en la edad (p = 0,000) y género (p = 0,005) Además, se realizó una comparación con una población similar: 70 a 75 años = 0,6 (d de Cohen), 76 a 79 años = 0,98 (d de Cohen) y >80 años = 0,98 (d de Cohen).

Conclusiones

El presente estudio señala los valores normativos para SPPB. La funcionalidad de las personas disminuye a medida que avanza la edad. A pesar de los hallazgos actuales que los profesionales de la salud disponen para una detección más eficaz de la fragilidad, muchos de ellos aún no se han traducido a la práctica clínica.

Beneficial effects of an intergenerational exercise intervention on health-related physical and psychosocial outcomes in Swiss preschool children and residential seniors: a clinical trial

Background

Intergenerational exercise possesses the potential to becoming an innovative strategy for promoting physical activity in seniors and children. Although this approach has gained attraction within the last decade, controlled trials on physical and psychosocial effects have not been performed yet.

Methods

Sixty-eight healthy preschool children (age: 4.9 y (SD 0.7)) and 47 residential seniors (age: 81.7 y (7.1)) participated in this five-armed intervention study. All participants were assigned to either an intergenerational (IG), peer (PG) or a control group (CON). Children were tested on gross motor skills (TGMD-2), jump performance and handgrip strength. Social-emotional skills questionnaires (KOMPIK) were assessed by kindergarten teachers. Seniors performed the Short Physical Performance Battery (SPPB), including gait speed. Arterial stiffness parameters were also examined. Questionnaires assessing psychosocial wellbeing were filled in with staff. IG and PG received one comparable exercise session a week lasting 45 minutes for 25-weeks. CON received no intervention. Measurements were performed before and after the intervention.

Results

In children: IG improved all measured physical parameters. When adjusted for baseline values, large effects were observed in favor of IG compared to CON in TGMD-2 (Cohen's d=0.78 [0.33;1.24]) and in handgrip strength (d = 1.07 [0.63;1.51]). No relevant differences were found in KOMPIK between groups (-0.38<d≤0.14). In seniors: IG showed moderate to very large improvements in all main physical performance (0.61<d≤2.53) and psychosocial parameters (0.89<d≤1.20) compared to CON.

Conclusion

IG children showed large benefits in motor skills compared to CON while IG seniors benefit especially in psychosocial wellbeing and functional mobility necessary for everyday life. Intergenerational exercise is comparable and in certain dimensions superior to peer group exercise and a promising strategy to integratively improve mental health as well as physical fitness in preschool children and residential seniors.

[Physical exercise impact on variables related to emotional and functional well-being in older adults]

BACKGROUND AND AIM

The benefits of the physical exercise in aging, and specially in frailty, have been associated with reduced risk of mortality, chronic disease, and cognitive and functional impairments. Multi-component training, which combines strength, endurance, balance, and gait training, represents the most beneficial kind of physical exercise in older adults.

METHODS

Given the effectiveness of the multi-component training, a physical exercise program «Actívate» (based on the methodology Vivifrail), with the focus on «active aging», was conducted in the present study. Forty-nine older adults over 60 years participated in this program.

RESULTS

The physical exercise intervention led to a reduction in diastolic blood pressure, pain threshold and sleep disturbances (e. g. hypersomnia) (t ≥ 2.72, p < 0.01), as well as an increase of walking speed (t = 7.84, p ≤ 0.001). Further, quality of life factors (GENCAT scale), like emotional well-being, personal development, physical well-being, self-determination, and social inclusion, were greater after intervention (t ≥ -2.06, p < 0.05).

CONCLUSIONS

These findings underline the benefits of multi-component training in functionality of older adults, and further, provide relevant aspects about the modulation of pain perception, sleep disturbances, social factors and physical and emotional well-being. Physical exercise programs such as «Actívate» should be promoted, in order to encourage healthy lifestyle habits, in the older adults' population.

[Prevalence of fear of falling and related factors in community-dwelling older people]

Objetivo

El objetivo general del estudio es conocer la prevalencia de la preocupación a caer en personas mayores, independientes para la deambulación, que viven en la comunidad, según la versión reducida del FES-I y los factores asociados que influyen en esta preocupación.

Diseño

Estudio descriptivo transversal.

Emplazamiento

Centro de Salud El Greco (Getafe), Gerencia Asistencial de Atención Primaria de Madrid.

Participantes

Ciento ochenta y nueve pacientes ≥ 70 años independientes o con dependencia funcional leve-moderada (índice de Barthel ≥ 60) e independientes para la deambulación (camina 45 min sin ayuda o con bastón). El estudio se ofreció a 328 personas: 217 aceptaron y rechazaron 111.

Mediciones principales

La variable dependiente, miedo a caerse (MC), fue evaluada mediante el cuestionario Short FES-I, considerando como punto de corte para el cribado positivo del MC una puntuación ≥ 11. Como variables independientes se consideraron: índice de Barthel, escala Downton, prueba de fragilidad Short Physical Performance Battery (SPPB), caídas en el último año, lesiones asociadas a las caídas, tiempo desde la última caída, déficit sensorial, uso de dispositivos de la marcha, comorbilidad y tratamiento farmacológico.

Resultados

La prevalencia del MC fue del 42,9% (IC 95%: 35,5-50,2). Los factores asociados al MC en el análisis multivariante final fueron: sexo femenino, vivir solo, alto riesgo de caídas, presencia de fragilidad, uso de hipotensores y lesiones asociadas a caídas previas.

Conclusiones

La prevalencia del miedo a caer en personas mayores es elevada. Los profesionales de atención primaria deben sistematizar el cribado de este problema de salud, priorizando especialmente en las personas que presentan los siguientes factores de riesgo: ser mujer, vivir solo, tener una puntuación baja en el SPPB (como indicador de fragilidad) o presentar un elevado riesgo de caídas.

Impacts of Physical Environment Perception on the Frailty Condition in Older People

Frailty increases the vulnerability of older people who commonly develop a syndrome leading to growing dependence and finally often death. Physical environment conditions may affect the severity of the syndrome positive or negatively. The main objective of this study was to analyse the conditions of different urban physical environments and their relationship with the frailty syndrome in older people. Geographic Information Systems (GIS) analyses were performed to detect global and local geographic clustering. Investigating 284 adults with ages from 60 to 74 years old from Talca City, Chile, we found spatial clustering of frailty conditions registered for older people, with hotspots of high and low values associated with areas of different urban infrastructures and socioeconomic levels into the city. The spatial identifications found should facilitate exploring the impact of mental health programmes in communities exposed to disasters like earthquakes, thereby improving their quality of life as well as reducing overall costs. Spatial correlation has a great potential for studying frailty conditions in older people with regard to better understanding the impact of environmental conditions on health.

Functional capacity and physical performance of community-dwelling elderly: a longitudinal study

This study aimed to verify the occurrence of changes in the functional capacity and physical performance of community-dwelling elderly and its determining factors over a two-year period. This is a quantitative, observational and longitudinal household survey conducted in 2014 and 2016, with the participation of 380 elderly from Uberaba, Minas Gerais. The following instruments were used: The Mini-Mental State Examination and questionnaires with sociodemographic/economic, clinical and life habits data. The functional capacity was evaluated through the Katz Index and Lawton-Brody's scale. Physical performance was verified through the Short Physical Performance Battery. A descriptive, bivariate and linear multiple regression analysis was conducted, with a significance level of α < 0.05. The results showed reduced functional capacity for the instrumental activities of daily living and physical performance in a two-year period. The determining factors for both outcomes were age group, occupational activity, and physical activity. Schooling was a specific factor only for the instrumental activities of daily living, and gender and the number of medicines used, for physical performance.

Normative Values for the Short Physical Performance Battery (SPPB) and Their Association With Anthropometric Variables in Older Colombian Adults. The SABE Study, 2015

Background: The short physical performance battery (SPPB) is a physical performance test of lower extremity function designed for non-disabled older adults. We aimed to establish reference values for community-dwelling Colombian adults aged 60 years or older in terms of (1) the total score; (2) the three subtest scores (walking speed, standing balance performance, and five times sit-to-stand test); and (3) the time to complete the five times sit-to-stand test, s and the walking speed test. Additionally, we sought to explore how much of the variance in the SPPB subtest scores could be explained by anthropometric variables (age, body mass, height, body mass index, and calf circumference).

Methods: Participants were men and women aged 60 years or older who participated in the Health and Well-being and Aging Survey in Colombia, 2015. A sample of 4,211 participants (57.3% women) completed the SPPB test, and their anthropometric variables were evaluated. Age-specific percentiles were calculated using the LMS method (3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles).

Results: The mean SPPB total score for the entire sample was 8.73 (2.0) points. On average, the total SPPB score was 0.85 points greater in men than in women (p < 0.001). Significant sex differences were observed in all three age groups tested (60–69, 70–79, and 80+ years). In the full sample, our findings suggested that age, body mass, height, body mass index, and calf circumference are significant contributors to walking speed (p < 0.001) after controlling for confounding factors, including ethnicity, socioeconomic status, and urbanicity.

Conclusions: Percentile values are of interest to identify target populations for primary prevention and to estimate the proportion of high or low values for SPPB measures in community-dwelling Colombians aged at least 60 years.

Measuring and monitoring skeletal muscle function in COPD: current perspectives

Skeletal muscle dysfunction is an important systemic consequence of chronic obstructive pulmonary disease (COPD) that worsens the natural cause of the disease. Up to a third of all people with COPD express some form of impairment which encompasses reductions in strength and endurance, as well as an increased fatigability. Considering this complexity, no single test could be used to measure and monitor all aspects of the impaired skeletal muscle function within the COPD population, resulting in a wide range of available tests and measurement techniques. The aim of the current review is to highlight current and new perspectives relevant to skeletal muscle function measurements within the COPD population in order to provide guidance for researchers as well as for clinicians. First of all, standardized and clinically feasible measurement protocols, as well as normative values and predictive equations across the spectrum of impaired function in COPD, are needed before assessment of skeletal muscle function can become a reality in clinical praxis. This should minimally target the quadriceps muscle; however, depending on the objective of measurements, eg, to determine upper limb muscle function or walking capacity, other muscles could also be tested. Furthermore, even though muscle strength measurements are important, current evidence suggests that other aspects, such as the endurance and power capacity of the muscle, should also be considered. Moreover, although static (isometric) measurements have been favored, dynamic measurements of skeletal muscle function should not be neglected as they, in a larger extent than static measurements, are related to tasks of daily living. Lastly, the often modest relationships between functional tests and skeletal muscle function measurements indicate that they evaluate different constructs and thus cannot replace one another. Therefore, for accurate measurements of skeletal muscle function in people with COPD, specific and formal measurements should still be prioritized.

Does adding an integrated physical therapy and neuromuscular electrical stimulation therapy to standard rehabilitation improve functional outcome in elderly patients with pneumonia? A randomised controlled trial

OBJECTIVE

To compare the effects of an integrated programme of physical and electrical therapy to standard rehabilitation to improve physical and functional performance in elderly patients with pneumonia.

DESIGN

Randomized clinical trial. The study was registered in the ClinicalTrial.gov website (identifier: NCT02515565).

SETTING

University Hospital.

SUBJECTS

In total, 185 elderly patients with pneumonia were eligible for the study, of which 95 were finally randomized.

INTERVENTIONS

Patients were randomized to a control group which received the standard treatment or to an intervention group which received additionally an integrated programme of physical and electrical therapy.

MAIN MEASURES

Demographic and clinical information was acquired. Pulmonary function, length of hospital stay, handgrip strength, independence levels and comorbidities were assessed as descriptive outcomes. The main outcome measure was functional and physical performance, evaluated with the short physical performance battery. Secondary outcome measures were respiratory symptoms including dyspnoea, fatigue and cough.

RESULTS

Mean age of patients was 74.92 (11.03) years in the intervention group and 72.53 (9.24) years in the control group. Significant between groups differences (P < 0.05) were found in short physical performance battery chair stand test (2.17 (0.97) vs. 0.58 (0.61)) and total score (5.91 (3.61) vs. 4.15 (3.15)). The intervention group showed better performance than the control group in both cases. Fatigue (32.04 (18.58) vs. 46.22 (8.90)) and cough (18.84 (2.47) vs. 17.40 (3.67)) showed higher improvement in the intervention group, and significant differences were observed between the groups.

CONCLUSION

An integrated programme of physical and electrical therapy during hospitalization improves physical and functional performance in patients with pneumonia.

Effectiveness of a muticomponent workout program integrated in an evidence based multimodal program in hyperfrail elderly patients: POWERAGING randomized clinical trial protocol

BACKGROUND

Short-term and mid-term comparison of the efficacy of a multimodal program that incorporates a therapeutic workout program, medication review, diet adjustment and health education, in comparison to the standard medical practice in the improvement of the neuromuscular and physiological condition. Furthermore, it is intended to analyse the maintenance of these effects in a long-term follow-up (12 months) from the onset of the intervention.

METHODS

A randomized clinical trial of elderly frail patients drawn from the Clinical Management Unit "Tiro de Pichón", Health District of Malaga, will be included in the study (after meeting the inclusion / exclusion criteria) will be randomized in two groups: a control group that will undergo an intervention consistent of medication review + diet adjustment + health education (regular workout recommendations within a complete advice on healthy lifestyles) and an experimental group whose intervention will consist of a multimodal treatment: therapeutic workout program+ medication review+ diet adjustment + health education. The sociodemographic, clinical and tracing variables will be reflected at the beginning of the study. In addition, the follow-up variables will be gathered at the second and sixth months after the beginning of the treatment and at the third and sixth months after the treatment (follow-up). The follow-up variables that will be measured are: body mass index, general health condition, fatigue, frailty, motor control, attention- concentration- memory, motor memory, spatial orientation, grip strength, balance (static, semi-dynamic), gait speed and metabolomics. A descriptive analysis of the sociodemographic variables of the participants will be conducted. One-Factor ANOVA will be used for the Within-Subject analysis and as for the Between-Subject analysis, the outcome variables between both the groups in each moment of the data collection will be compared.

DISCUSSION

A multimodal program that incorporates a therapeutic workout program, medication review, diet adjustment and health education may be effective treatment to reduce the functional decline in elderly. The results of the study will provide information on the possible strengths and benefits in multimodal program in elderly.

Frailty Level Monitoring and Analysis after a Pilot Six-Week Randomized Controlled Clinical Trial Using the FRED Exergame Including Biofeedback Supervision in an Elderly Day Care Centre

Background: Frailty is a status of extreme vulnerability to endogenous and exogenous stressors exposing the individual to a higher risk of negative health-related outcomes. Exercise using interactive videos, known as exergames, is being increasingly used to increase physical activity by improving health and the physical function in elderly adults. The purpose of this study is to ascertain the reduction in the degree of frailty, the degree of independence in activities of daily living, the perception of one's state of health, safety and cardiac healthiness by the exercise done using FRED over a 6-week period in elderly day care centre. Material and Methods: Frail volunteers >65 years of age, with a score of <10 points (SPPB), took part in the study. A study group and a control group of 20 participants respectively were obtained. Following randomisation, the study group (20) took part in 18 sessions in total over 6 months, and biofeedback was recorded in each session. Results: After 6 weeks, 100% of patients from the control group continued evidencing frailty risk, whereas only 5% of patients from the study group did so, with p < 0.001 statistical significance. In the case of the EQ-VAS, the control group worsened (-12.63 points) whereas the study group improved (12.05 points). The Barthel Index showed an improvement in the study group after 6 weeks, with statistically significant evidence and a value of p < 0.003906. Safety compliance with the physical activity exceeded 87% and even improved as the days went by. Discussion: Our results stand out from those obtained by other authors in that FRED is an ad hoc-designed exergame, significantly reduced the presence and severity of frailty in a sample of sedentary elders, thus potentially modifying their risk profile. It in turn improves the degree of independence in activities of daily living and the perception of one's state of health, proving to be a safe and cardiac healthy exercise. Conclusions: The study undertaken confirms the fact that the FRED game proves to be a valid technological solution for reducing frailty risk. Based on the study conducted, the exergame may be considered an effective, safe and entertaining alternative.

The Impact of Multiple Dimensions of Socioeconomic Status on Physical Functioning Across the Life Course

Objective: We used the Physical Performance Across the LifeSpan Study to investigate the relationships of multiple indicators of socioeconomic status (SES), both in early life and late life, with physical function. Method: We examined associations between multiple early and late life SES indicators with physical function measured by aerobic endurance, gait speed, and lower body strength. Results: Higher participant education and household income were associated with increased physical function. In our age-stratified analysis, we observed widening SES disparities with increasing age among those in the two younger strata with lower SES associated with worse physical function. Finally, we observed an association between socioeconomic trend and gait speed, aerobic endurance, and lower body strength. There was also an association between lower aerobic endurance and being in a downward socioeconomic trend. Discussion: These findings highlight the significance of considering multiple dimensions of the social environment as important correlates of physical functioning across the life course.

Efficacy of the Otago Exercise Programme to reduce falls in community-dwelling adults aged 65-80 years old when delivered as group or individual training

AIM

This study will compare how falls can be reduced in non-institutionalized older Spanish adults aged 65-80 years by providing group or individual exercise sessions using the Otago Exercise Programme.

BACKGROUND

The Otago Exercise Programme is a progressive home-based exercise programme, where trained health professionals help people engage in strength, balance and endurance exercises. Its format is based on the evidence from four clinical trials. The benefits of the Otago Exercise Programme are the same for people who have and have not suffered falls and it can also be used for visually impaired people.

DESIGN

A multicentre, simply blinded, randomized, non-inferiority clinical trial, with two arms-group training and individual training-that started in January 2017 and will continue until December 2019.

METHODS

Each study group has 364 subjects, who will take part in four individual or group sessions delivered mainly by nurses over an 8-week period, with a reinforcement session 6 months later. Data will be collected at baseline and after 6 and 12 months. The fall percentage will be the most relevant clinical variable and we will also consider safety, viability, compliance, economic analysis and therapeutic value. Approval and funding was granted in December 2016 for this 3-year study by the Spanish Health Research Fund (PI16CIII/00031).

DISCUSSION

Older people from 65-80 years old tend to be more isolated and tackling worries about falls can improve social activities and independence. It has been shown that group training provides better adherence to exercise than individual training and this study will test that hypothesis for the Otago Exercise Programme.

Validation of the Spanish version of the Pittsburgh Fatigability Scale for older adults

BACKGROUND

The Pittsburgh Fatigability Scale (PFS) is the only validated scale for measuring perceived fatigability in older adults.

AIMS

We validated the PFS Spanish version by assessing convergent validity with respect to several measures of physical performance, physical activity, physical function and disability.

METHODS

A cross-sectional validation study of 79 community-dwelling older adults aged 70 and older from Barcelona, Spain was included. Translation-retrotranslation was performed. Convergent validity was assessed in relation to physical activity and performance measurements, and analyzed with Spearman correlation coefficients, a linear trend test and non-linear regression. We also assessed the discriminant validity of the PFS physical score between participants with different physical activity and performance levels.

RESULTS

Higher PFS physical scores were inversely associated with the Short Physical Performance Battery (r = - 0.5, p < 0.001) and weak to moderately correlated with gait speed (r = 0.38, p = 0.001), and self-reported weekly walking time (r = 0.24, p = 0.035).

CONCLUSION

The PFS is a novel, brief instrument to assess fatigability in Spanish-speaking older adults, with good convergent validity against physical performance measurements. Thus, the PFS can be used in Spanish-speaking populations.

[Detection of the largest population susceptible to prescription of a program of exercises in Primary Care to prevent frailty]

Objetivo

Identificar a la población mayor de 70 años atendida en Atención Primaria, susceptible de participar en un programa de ejercicio físico para prevenir fragilidad. Analizar la concordancia entre 2 criterios para seleccionar la población beneficiaria del programa.

Diseño

Estudio transversal de base poblacional.

Emplazamiento

Atención Primaria.

Participantes

Mayores de 70 años no frágiles residentes del Barrio Peñagrande (distrito Fuencarral, Madrid) pertenecientes a la cohorte de Peñagrande localizables en 2015 y que aceptaron participar (n = 307).

Mediciones principales

La variable principal del estudio es la necesidad de prescripción de ejercicio en Atención Primaria en personas mayores de 70 años; se identificó a través de 2 definiciones diferentes: personas prefrágiles (1 o 2 de los 5 criterios de Fried) y personas independientes con desempeño físico limitado, definida por los criterios del documento de consenso sobre prevención de fragilidad y caídas en la persona mayor (mayor de 70 años independiente y con puntuación total del SPPB < 10).

Resultados

El 63,84% de los participantes (n = 196) necesitan prescripción del ejercicio por ser prefrágiles y/o por cumplir los criterios definidos en el documento de consenso. En 82 casos cumplían los 2 criterios (prefragilidad y desempeño físico disminuido), 80 eran prefrágiles con desempeño físico normal y 34 eran robustos con desempeño físico limitado. La concordancia entre ambos criterios es débil (índice kappa 0,27).

Conclusión

Casi 2 tercios de los mayores presentan algún tipo de limitación funcional. Los criterios del documento de consenso para prevenir la fragilidad detectan a la mitad de los individuos prefrágiles de la comunidad.

FRED: Exergame to Prevent Dependence and Functional Deterioration Associated with Ageing. A Pilot Three-Week Randomized Controlled Clinical Trial

Introduction: Frailty syndrome and advanced age may decrease the acceptance of illness and quality of life, and worsen patients' existing health conditions, as well as leading to an increase in health care expenses. Purpose: The purpose of this study is to reduce frailty risk via the use of a FRED game which has been expressly designed and put together for the study. Materials and methods: A total of 40 frail volunteers with a score of <10 points in the short physical performance battery (SPPB) took part in a feasibility study in order to validate the FRED game. Following randomisation, the study group (20 subjects) took part in nine sessions of 20 min each over a three-week period. The control group (19 subjects) continued to lead their daily lives in the course of which they had no physical activity scheduled; Results: After three weeks and having taken part in nine physical activity sessions with the FRED game, 60% of subjects from the study group (12/20) obtained a score of ≥10 points at the end of the study, i.e., less risk of evidencing frailty. This result proved to be statistically significant (p < 0.001). The degree of compliance with and adherence to the game was confirmed by 100% attendance of the sessions. Discussion: Our findings support the hypothesis that FRED, an ad hoc designed exergame, significantly reduced the presence and severity of frailty in a sample of sedentary elders, thus potentially modifying their risk profile. Conclusions: The FRED game is a tool that shows a 99% certain improvement in the degree of frailty in frail elderly subjects. The effectiveness of the design of ad hoc games in a certain pathology or population group is therefore evidenced.

The Feldenkrais Method improves functioning and body balance in people with intellectual disability in supported employment: A randomized clinical trial

Loss of functioning and age-related health problems tend to appear earlier in individuals with intellectual disability (ID) than in their non-disabled peers. The Feldenkrais method (FM) is a movement-based form of learning that enhances body balance and physical functioning. We carried out an intervention based on Awareness Through Movement, a form of the FM. Thirty-two middle-aged (48.94±6.01years old) adults with ID who were in supported employment were recruited and randomly assigned to the experimental group (EG) or control group (CG). The EG received 30 Awareness Through Movement classes while the CG did not receive any movement-based intervention. Physical functioning (body balance, gait speed and chair stands) was assessed with the Short Physical Performance Battery (SPPB) and balance by stabilometry. After 30 FM classes, individuals in the EG had significantly improved their chair stand test score (p<0.005) and SPPB total score (p<0.005), and reduced their sway area (p<0.05) in the stabilometric test. These results indicate that the FM could be a good tool for the prevention of loss of functioning and body balance in middle-aged individuals with ID.

Physical Activity Protects Men but Not Women for Sarcopenia Development

Objective: Sarcopenia is among the most deleterious effects of aging. The objective of this study was to analyze the relationship between performance tests and muscular volume over the life span of male and female participants. Method: A correlation study was conducted with healthy individuals (50 males and 47 females) between the ages of 20 and 94; the study group included active older people, sedentary younger people, and young athletes. Muscular volume was determined by tomography and muscular performance (4-meter speed tests [4 MSTs], chair test, and handgrip test), and a correlation analysis between the groups was performed. Results: Sex-related differences were observed between the variables; in males, muscle volume and functional parameters were closely related with age and physical activity, whereas in females, they were not related at all. Conclusion: Male and female muscle volume and performance demonstrate strong differences, which should be considered during clinical evaluations of sarcopenia.

Validation and comparison of instruments to identify frail patientes in primary care settings: Study protocol

BACKGROUND

In the last few years several indices and tools, aimed at identifying frail subjects in various care settings have been developed. However, to date none of them has been incorporated into usual practice in the primary care setting. The purposes of this study are: 1) to evaluate the predictive capacity of the Tilburg Frailty Indicator (TFI), the Gérontopôle Frailty Screening Tool (GFST) and the KoS model together with two biomarker levels (SOX2 and p16INK4a) for adverse events related to frailty; 2) to determine differences in the use of healthcare services according to frailty.

METHODS/DESIGN

Prospective multicentre cohort study with a 2-year follow-up. The study will be performed in primary care centres of Gipuzkoa and Costa del Sol, both located in Spain. Autonomous, non-institutionalized individuals aged 70 and over that agree to participate in this study will constitute the study population. A total of 900 individuals will be randomly selected from the healthcare administrative data bases of the participating health services. Data will be collected at baseline and at 1 and 2 years. The main independent variables assessed at baseline will be TFI outcomes, GFST and the KoS model, together with the expression of SOX2 and p16INK4a levels. During follow-up, loss of autonomy, the occurrence of death and consumption of healthcare resources will be assessed.

DISCUSSION

The main focus of this work is the identification and evaluation of several instruments constructed under different rationales to identify frail subjects in primary care settings. The resulting outcomes have potential for direct application to the primary care practice. Early identification of the onset of functional impairment of elderly is an essential, still unresolved aspect in the prevention of dependence in the scope of primary care.

Relationships between physical performance and knee and hip osteoarthritis: findings from the European Project on Osteoarthritis (EPOSA)

BACKGROUND

poor physical performance (PP) is known to be associated with disability, lower quality of life and higher mortality rates. Knee and hip osteoarthritis (OA) might be expected to contribute to poor PP, through joint pain and restricted range of movement. Both clinical and self-reported OA are often used for large-scale community and epidemiological studies.

OBJECTIVE

to examine the relationships between hip and knee OA and PP in a large data set comprising cohorts from six European countries.

METHODS

a total of 2,942 men and women aged 65-85 years from the Germany, Italy, Netherlands, Spain, Sweden and the UK were recruited. Assessment included an interview and clinical assessment for OA. PP was determined from walking speed, chair rises and balance (range 0-12); low PP was defined as a score of ≤9.

RESULTS

the mean (SD) age was 74.2 (5.1) years. Rates of self-reported OA were much higher than clinical OA. Advanced age, female gender, lower educational attainment, abstinence from alcohol and higher body mass index were independently associated with low PP. Clinical knee OA, hip OA or both were associated with a higher risk of low PP; OR (95% CI) 2.93 (2.36, 3.64), 3.79 (2.49, 5.76) and 7.22 (3.63, 14.38), respectively, with relationships robust to adjustment for the confounders above as well as pain.

CONCLUSION

lower limb OA at the hip and knee is associated with low PP, and for clinical diagnosis relationships are robust to adjustment for pain. Those at highest risk have clinical OA at both sites.

Associations of the antioxidant capacity and hemoglobin levels with functional physical performance of the upper and lower body limbs

Herein we considered the role of oxidative stress on deficiencies of functional physical performance that could affect a future pre-frailty condition. Using principal component analyses (PCA), we created new variables to better describe the functionality regarding the physical performance of the upper and lower body limbs. Gait speed and the Short Physical Performance Battery (SPPB) score were classified by PCA to describe functional performance of the lower body limbs. Variables describing the general physical status, including weekly consumption of kilocalories and the musculoskeletal index, were classified together with grip strength of the dominant hand as indicators of functional performance of the upper body limbs. An intimate association between the functional physical performance of the upper body limbs and the total antioxidant capacity was observed in older subjects. Low levels of total antioxidant capacity were found in women 76 years or younger with deficiencies in the physical performance of both upper and lower body limbs. Similarly, we observed a close association between the functional physical performance of the lower body limbs and the levels of hemoglobin. In particular, low levels of hemoglobin were mostly found in men older than 76 years of age, showing impaired functional physical performance. In addition, the physical performance of the lower body limbs was shown to be more important than that of the upper body limbs in the statistical association with pre-frailty in the elderly. Therefore, specific low levels of hemoglobin and deficient oxidative defense in the elderly could significantly affect the functional physical performance and future outcomes of pre-frailty.

Validity and reliability of the Short Physical Performance Battery (SPPB): a pilot study on mobility in the Colombian Andes

OBJECTIVES

To assess the validity (convergent and construct) and reliability of the Short Physical Performance Battery (SPPB) among non-disabled adults between 65 to 74 years of age residing in the Andes Mountains of Colombia.

METHODS

Design Validation study;

PARTICIPANTS

150 subjects aged 65 to 74 years recruited from elderly associations (day-centers) in Manizales, Colombia.

MEASUREMENTS

The SPPB tests of balance, including time to walk 4 meters and time required to stand from a chair 5 times were administered to all participants. Reliability was analyzed with a 7-day interval between assessments and use of repeated ANOVA testing. Construct validity was assessed using factor analysis and by testing the relationship between SPPB and depressive symptoms, cognitive function, and self rated health (SRH), while the concurrent validity was measured through relationships with mobility limitations and disability in Activities of Daily Living (ADL). ANOVA tests were used to establish these associations.

RESULTS

Test-retest reliability of the SPPB was high: 0.87 (CI95%: 0.77-0.96). A one factor solution was found with three SPPB tests. SPPB was related to self-rated health, limitations in walking and climbing steps and to indicators of disability, as well as to cognitive function and depression. There was a graded decrease in the mean SPPB score with increasing disability and poor health.

CONCLUSION

The Spanish version of SPPB is reliable and valid to assess physical performance among older adults from our region. Future studies should establish their clinical applications and explore usage in population studies.
