Total carotenoid intake is associated with reduced loss of grip strength and gait speed over time in adults: The Framingham Offspring Study

BACKGROUND

Lower antioxidant serum concentrations have been linked to declines in lean mass and physical function in older adults. Yet population data on the effect of dietary antioxidants on loss of muscle strength and physical function are lacking.

OBJECTIVE

We sought to determine the association of antioxidant intake [vitamin C, vitamin E, and total and individual carotenoids (α-carotene, β-carotene, β-cryptoxanthin, lycopene, and lutein + zeaxanthin)] with annualized change in grip strength and gait speed in adults from the Framingham Offspring study.

METHODS

This prospective cohort study included participants with a valid FFQ at the index examination and up to 2 prior examinations and at ≥2 measures of primary outcomes: grip strength (n = 2452) and/or gait speed (n = 2422) measured over 3 subsequent examinations. Annualized change in grip strength (kg/y) and change in gait speed (m/s/y) over the follow-up period were used. Linear regression was used to calculate β coefficients and P values, adjusting for covariates.

RESULTS

Mean ± SD age of participants was 61 ± 9 y (range: 33-88 y). Median intakes (IQR, mg/d) of vitamin C, vitamin E, and total carotenoid across available examinations were 209.2 (133.1-394.2), 27.1 (7.4-199.0), and 15.3 (10.4-21.3), respectively. The mean follow-up time was ∼12 ± 2 y (range: 4.5-15.4 y). In the sex-combined sample, higher intakes of total carotenoids, lycopene, and lutein + zeaxanthin were associated with increased annualized change in grip strength [β (SE) per 10-mg higher intake/d, range: 0.0316 (0.0146) to 0.1223 (0.0603) kg/y)]. All antioxidants except for vitamin C were associated with faster gait speed [β (SE) per 10-mg higher intake/d, range: 0.00008 (0.00004) to 0.0187 (0.0081) m/s/y].

CONCLUSIONS

Higher antioxidant intake was associated with increase in grip strength and faster gait speed in this cohort of adults. This finding highlights the need for a randomized controlled trial of dietary antioxidants and their effect on muscle strength and physical function.

The effect of physical exercise on rheumatoid arthritis: An overview of systematic reviews and meta-analysis

AIMS

To determine which outcomes will be improved by different exercise interventions and the evidence quality for each intervention.

DESIGN

Overview of systematic reviews and meta-analysis.

DATA SOURCES

PubMed, Cochrane, Web of Science, CINAHL, and Embase. Published from the establishment of the database to 3 September 2019.

REVIEW METHODS

AMSTAR 2 and PRISMA were used to evaluate methodological and reporting quality. Evidence quality of the effect of each intervention was assessed according to GRADE guidelines. Meta-analysis of original studies was conducted for comparison of systematic reviews and to explore the effect of different exercise interventions on the same outcome.

RESULTS

Ten systematic reviews were included in the overview. A significant improvement was seen in: aerobic exercise for aerobic capacity; strength training for erythrocyte sedimentation rate and 50-foot walking time; aerobic exercise combined with strength training for aerobic capacity, physical function, and fatigue; hand exercise for hand function.

CONCLUSIONS

For the maximum benefit of rheumatoid arthritis (RA) patients, different exercise methods should be selected according to the symptoms. For RA patients, any exercise is better than no exercise, but the intensity, frequency, and period of exercise for better results are not determined.

IMPACT

What problem did the study address is which outcomes will be improved by different exercise interventions. For maximum benefit for RA patients, different exercise methods should be selected according to symptoms. The research summarized the evidence of exercise rehabilitation of RA and will help RA patients or their caregivers choose the appropriate type of exercise, which will play a positive role on the rehabilitation of patients with RA.

Clinical Effectiveness of a Self-Regulation Theory-Based Self-Management Intervention for Adults With Knee Osteoarthritis: A Long-Term Follow-Up

PURPOSE

To determine if there are long-term effects of a self-management intervention guided by self-regulation theory for adults with knee osteoarthritis at 6 and 12 months after completing the intervention.

DESIGN

This long-term follow-up study used a longitudinal quasi-experimental design with repeated measures.

METHODS

A convenience sample of 127 patients with knee osteoarthritis who were 45 to 64 years of age were recruited from outpatient clinics in Taiwan. The Self-Management Needs of Knee Osteoarthritis Scale was used to assess self-management needs at enrollment (baseline). To evaluate the long-term effects, participants were reassessed at 6 and 12 months after the intervention using the following questionnaires: The Knee Injury and Osteoarthritis Outcome Score, Healthcare Outcomes, and the Short-Form Health Survey. Generalized estimating equations compared assessments at baseline with scores at 6 and 12 months following completion of the intervention. Multiple regression was used to examine significant factors associated with the assessments.

FINDINGS

Participants had moderate levels of self-management needs. When assessments at 6 months were compared with baseline, scores for knee symptoms and physical function and quality of life showed significant improvements; significant reductions were seen in body mass index, unplanned medical consultations, and pain medication doses. Assessments at 12 months compared with baseline measures indicated these improvements were maintained. These improvements were significant from baseline measures at both 6 months and 12 months after adjustments were made for time and other significant variables.

CONCLUSIONS

Twelve months after completion of the intervention, the significant improvements seen at 6 months were maintained. Our findings demonstrate that the self-management intervention had significant long-term effects on knee symptoms and physical function, body mass index and pain medication doses, and overall quality of life for patients with moderate self-management needs of knee osteoarthritis.

CLINICAL RELEVANCE

Clinical care of knee osteoarthritis that includes a self-regulation theory-based self-management intervention could provide long-term benefits to patients.

Impact of a Rehabilitation Protocol and a Dedicated Therapist in the Intensive Care Unit on Physical Function and Activities of Daily Living

Objectives:

The goal of this study was to determine the effects of an intensive care unit (ICU) rehabilitation protocol with dedicated therapists on the physical function and activities of daily living (ADL) of patients on discharge from the ICU.

Methods:

This retrospective study included patients who started rehabilitation during their ICU stay. Patients were divided into three groups: the Usual Care group (before the introduction of the rehabilitation protocol), the Protocol group (after the introduction of the rehabilitation protocol), and the PT + Protocol group (with a dedicated therapist in addition to the rehabilitation protocol). The standard interventions in the Protocol group and the PT + Protocol group were set according to the protocol based on the level of consciousness and strength of each individual patient. Patients’ age, APACHE II score, length of ICU stay, length of hospital stay, and the Functional Status Score for the ICU (FSS-ICU) and Medical Research Council score (MRC score) on discharge from the ICU were compared among the three groups.

Results:

There were no significant differences among the three groups in age and APACHE II score. The MRC and FSS-ICU scores were significantly higher in the PT + Protocol and Protocol groups than in the Usual Care group. Furthermore, the lengths of ICU stay and hospital stay were lower in the PT + Protocol group than in the Usual Care group.

Conclusions:

Introduction of the rehabilitation protocol improved the limb strength and ADL of patients. Moreover, the presence of dedicated therapists in addition to the protocol reduced the lengths of ICU and hospital stays.

Reflections on the T Trials

BACKGROUND

This manuscript is a review and discussion of the published results of the T Trials.

OBJECTIVE

To re-examine the efficacy of testosterone replacement of hypogonadal men >65 years of age in the T Trials.

MATERIALS AND METHODS

The T Trials were a complex collection of seven double blind, placebo-controlled trials of the efficacy of testosterone as replacement therapy for older men with unequivocal hypogonadism. There were three main trials (sexual function; physical function; vitality) and four sub-trials (cognition; bone; anemia; and cardiovascular). All subjects participated in the main trials while more selective inclusion/exclusion criteria existed for the sub-trials. Subjects were excluded for perceived higher risk of prostate cancer and recent myocardial or cerebral vascular events.

RESULTS

The previously published results are reviewed here as seen in the context of this special issue on late-onset hypogonadism. In the T Trials, positive benefits were seen in the sexual function, bone, and anemia trials with small but significant benefits in the vitality trial. No benefit was seen in the cognition trial, partial benefit in physical function, and a negative benefit outcome seen in the cardiovascular trial. The later trial was underpowered and the results were described as exploratory. Adverse events were relatively uncommon in the 12-month treatment phase and additional 12-month post-treatment phase. The most frequent adverse effect ascribed to testosterone was erythrocytosis.

CONCLUSIONS

The T Trials studied the efficacy of testosterone replacement therapy on 788 men with low testosterone and symptoms of hypogonadism. The studies demonstrated benefits in four trials (sexual function, vitality, bone, and anemia); partial benefit in the physical function trial; no effect in the cognition trial; and a negative effect in the exploratory cardiovascular trial. The T Trials were not designed to assess long-term risks of testosterone in men.

Some gain for a small investment: An economic evaluation of an exercise program for people living in residential aged care

OBJECTIVE

To evaluate the cost-effectiveness of a 12-week Exercise Physiology (EP) program for people living in a residential aged care facility.

METHODS

A within-study pre- and postintervention design to calculate incremental cost-effectiveness ratios per quality-adjusted life years gained. A health service provider perspective was used.

RESULTS

Fifty-nine participants enrolled in a 12-week program. The program cost was A$514.30 per resident. At a willingness-to-pay threshold of A$64 000, the likelihood of being cost-effective of the program is approximately 60%, due to a small increase in participants' quality of life, as reported by care staff. The model showed great variance, depending on who rated the participants' quality of life outcomes.

CONCLUSION

It is uncertain that a 12-week EP program is cost-effective based on the evidence of the current trial. However, it appears that a low-cost program can produce small improvements for residents in care facilities.

Overall Health and the Influence of Physical Therapy on Physical Function Following Total Ankle Arthroplasty

BACKGROUND

The overall health and the importance of physical therapy for people following total ankle arthroplasty (TAA) have been understudied. Our purpose was to characterize the overall health of patients following TAA, and explore the frequency, influence, and patient-perceived value of physical therapy.

METHODS

People who received a TAA participated in this retrospective cohort online survey study. The survey included medical history questions and items from the Patient-Reported Outcomes Measurement Information System (PROMIS) Short Forms. Seven PROMIS domains, reflecting the biopsychosocial model of care (physical, mental, social), were included to examine participant overall health status in comparison to the general population. Items regarding physical therapy participation (yes/no), number of visits, and perceived value (scale 0-10; 10 = extremely helpful) were also included. Descriptive statistics were generated for participant characteristics, PROMIS domain T scores, and physical therapy questions. The influence of participant characteristics or physical therapy visits on PROMIS domain T scores that scored below the population mean were examined with multiple linear regression or ordinal regression.

RESULTS

The response rate was 61% (n=95). Average postoperative time was approximately 3 years (mean [SD]: 40.0 [35.3] months). Physical function and ability to participate in social roles and activities domain T scores were at least 1 SD below the population mean. Most patients received physical therapy (86%; 17.1 [11.0] visits) and found it helpful (7.2 [3.0]). Participant characteristics were minimally predictive of physical function and social participation T scores. Number of physical therapy visits predicted physical function T scores (P = .03).

CONCLUSIONS

Most health domain scores approached the population mean. Physical therapy was perceived to have a high value, and greater visits were related to greater physical function. However, lower physical function and social participation scores suggest that postoperative care directed toward these domains could improve the value of TAA and promote overall health.

LEVEL OF EVIDENCE

Level III, retrospective comparative study.

Exercise and Nutrition Interventions in Patients with Head and Neck Cancer during Curative Treatment: A Systematic Review and Meta-Analysis

The aim of this meta-analysis was to examine the effects of nutritional and physical exercise interventions and interventions combining these interventions during radiotherapy treatment for patients with head and neck cancer on body composition, objectively measured physical function and nutritional status. Systematic electronic searches were conducted in MEDLINE (PubMed interface), EMBASE (Ovid interface), CINAHL (EBSCO interface) and Cochrane Library (Wiley interface). We identified 13 randomized controlled trials (RCTs) that included 858 patients. For body composition, using only nutrition as intervention, a significant difference between treatment and control group were observed (SMD 0.42 (95CI 0.23-0.62), p < 0.001). Only pilot RCTs investigated combination treatment and no significant difference between the treatment and control groups were found (SMD 0.21 (95CI -0.16-0.58), p = 0.259). For physical function, a significant difference between treatment and control group with a better outcome for the treatment group were observed (SMD 0.78 (95CI 0.51-1.04), p < 0.001). No effects on nutritional status were found. This meta-analysis found significantly positive effects of nutrition and physical exercise interventions alone in favor of the treatment groups. No effects in studies with combined interventions were observed. Future full-scaled RCTs combining nutrition and physical exercise is warranted.

Health-Related Quality of Life and Physical Function in Individuals with Parkinson's Disease after a Multidisciplinary Rehabilitation Regimen-A Prospective Cohort Feasibility Study

Parkinson’s disease (PD) is a neurodegenerative disease and a multidisciplinary approach to rehabilitation has been suggested as the best clinical practice. However, very few studies have investigated the long-term effects of a multidisciplinary rehabilitation approach, particularly regarding whether this can slow the progression of PD. The purpose was to investigate the short- and long-term effect of a 2-week multidisciplinary rehabilitation regimen on the PD-related decline in health-related quality of life (HRQOL), mobility, and muscle function. Individuals with PD (IPD) participated in a 2-week inpatient multidisciplinary rehabilitation regimen that focused on improving HRQOL, mobility, and muscle function. Data from the primary outcome: HRQOL (Parkinson’s Disease Questionnaire 39, PDQ-39), secondary outcomes: handgrip strength, Timed-up and Go (TUG), Hospital Anxiety and Depression Scale (HADS), and Falls Efficacy Scale-International (FES-I) were compared at pre-visitation, before and after the 2-week regimen, and again at 4 and 10 months follow-up. In total, 224 patients with PD were included. There were short-term improvements in all outcomes. PDQ-39 was maintained at the same level as pre-visitation after 10 months follow-up. A 2-week multidisciplinary rehabilitation regimen improved short-term mobility, muscle function, and HRQOL in individuals with Parkinson’s disease. HRQOL was maintained after 10 months demonstrating long-term effects.

Comparison of the Effects of Four Treatment Techniques Commonly Used in Ureteral Stone Treatment on Patients' Daily Physical Functioning: An Observational Randomized-Controlled Study

Objective: To investigate the effect of four different techniques used in the treatment of ureteral stones on patients' daily physical functioning (PF) and quality of life (QoL). Materials and Methods: Patients who underwent ureterorenoscopy (URS)-with or without Double-J stenting (DJS)-and extracorporeal shock wave lithotripsy (SWL) were divided into four groups: Group I: SWL (n = 29), Group II: URS (n = 43), Group III: URS +4.8F DJS (n = 39), Group IV: URS +6F DJS (n = 42), and Group V: Control (n = 30). Short Form-36 (SF-36) was administered to each participant both preoperatively and 14 days after operation. Based on the SF-36 results, the changes in patients' PF and QoL were evaluated. Results: Ureteral stone treatment was performed in 202 patients. Of these, 153 patients who underwent an effective SWL or URS procedure in the first attempt were included in the study. Success rates in the first session were 53.7% (29/54) and 83.8% (124/148) for SWL and URS, respectively (p < 0.001). All the four groups were similar with regard to age, gender, body mass index, stone size, preoperative PF, and QoL. However, although postoperative PF, role limitations due to physical health, and energy/fatigue scores were similar in Group I, III, and IV, they were significantly higher in Group II. No major complication associated with SWL or URS occurred in any patient. However, in Group 2, DJS was inserted in three (7.7%) patients in the early postoperative period (within the first 48 hours) due to renal colic attacks secondary to ureterovesical junction mucosal edema. Conclusion: URS without DJS seems to be the most advantageous technique in the treatment of ureteral stones in terms of daily PF and QoL. However, it should be noted that patients undergoing URS may require postoperative emergency stenting, although rarely.

Risk Model for Decline in Activities of Daily Living Among Older Adults Hospitalized With Acute Myocardial Infarction: The SILVER-AMI Study

Background

Functional decline (ie, a decrement in ability to perform everyday activities necessary to live independently) is common after acute myocardial infarction (AMI) and associated with poor long‐term outcomes; yet, we do not have a tool to identify older AMI survivors at risk for this important patient‐centered outcome.

Methods and Results

We used data from the prospective SILVER‐AMI (Comprehensive Evaluation of Risk Factors in Older Patients With Acute Myocardial Infarction) study of 3041 patients with AMI, aged ≥75 years, recruited from 94 US hospitals. Participants were assessed during hospitalization and at 6 months to collect data on demographics, geriatric impairments, psychosocial factors, and activities of daily living. Clinical variables were abstracted from the medical record. Functional decline was defined as a decrement in ability to independently perform essential activities of daily living (ie, bathing, dressing, transferring, and ambulation) from baseline to 6 months postdischarge. The mean age of the sample was 82±5 years; 57% were men, 90% were White, and 13% reported activity of daily living decline at 6 months postdischarge. The model identified older age, longer hospital stay, mobility impairment during hospitalization, preadmission physical activity, and depression as risk factors for decline. Revascularization during AMI hospitalization and ability to walk a quarter mile before AMI were associated with decreased risk. Model discrimination (c=0.78) and calibration were good.

Conclusions

We identified a parsimonious model that predicts risk of activity of daily living decline among older patients with AMI. This tool may aid in identifying older patients with AMI who may benefit from restorative therapies to optimize function after AMI.

A Narrative Review on Measurement Properties of Fixed-distance Walk Tests Up to 40 Meters for Adults With Knee Osteoarthritis

Knee osteoarthritis (OA) is a serious disease and has no cure to date. Knee OA is a leading cause of functional limitation (e.g., difficulty walking). Walking speed is 1 method of quantifying difficulty with walking and should be assessed in clinical practice for adults with knee OA because it has prognostic value and is modifiable. Specifically, slow walking speed is associated with increased risk of adverse health outcomes, including all-cause mortality in adults with knee OA and can be modified by engaging in physical activity or exercise. However, at present, there is little consensus on the distance and instructions used to conduct the walk test. Distance is often selected based on space availability, and instruction varies, from asking the participants to walk at a comfortable pace versus as fast as possible. Therefore, the purpose of this narrative review is to summarize the measurement properties, strengths, and limitations of a fixed-distance walk test ≤ 40 meters in adults with knee OA. Good measurement properties in terms of reliability and validity were observed across the different testing protocols for fixed-distance walk test (i.e., any distance ≤ 40 m and fast- or self-paced). Therefore, clinicians and researchers can select a testing protocol that can safely and consistently be performed over time, as well as provide a practice trial to acclimatize the patients to the fixed-distance walk test.

Cerebral Amyloid-β Deposition Is Associated with Impaired Gait Speed and Lower Extremity Function

BACKGROUND

Impaired physical function (i.e., slowing of gait, muscle weakness, and poor mobility) is common in older adults with cognitive impairment and dementia. Evidence suggests that cerebral small vessel disease, specifically white matter lesions (WMLs), is associated with impaired physical function, but little research has been conducted to understand the specific role of Alzheimer's disease pathology in physical outcomes.

OBJECTIVE

The objective of this study was to examine the association between cerebral amyloid-β (Aβ) deposition and physical function in people with cognitive impairment.

METHODS

Thirty participants completed an 11C Pittsburgh compound B (PIB) position emission tomography (PET) scan to quantify global Aβ deposition using standardized uptake value ratio (SUVR). We assessed usual gait speed, muscle strength of the lower extremities, balance, and functional mobility using the Short Physical Performance Battery (SPPB) and the Timed Up and Go Test (TUGT). Multiple linear regression analyses examined the association between Aβ and each measure of physical function, adjusting for age, body mass index, and WML load.

RESULTS

Global PIB SUVR was significantly associated with usual gait speed (β= -0.52, p = 0.01) and SPPB performance (β= -0.47, p = 0.02), such that increased Aβ deposition was associated with reduced performance on both measures. Global PIB SUVR was not significantly associated with TUGT performance (β= 0.32, p = 0.08).

CONCLUSIONS

Cerebral Aβ deposition is associated with reduced gait speed, muscle strength, and balance in older adults with cognitive impairment independent of WML load. However, Aβ deposition was not associated with functional mobility.

Evaluation of beneficial effect of a dual-task exercise based on Japanese transitional games in older adults: a pilot study

Not only does Japan has the world's longest healthy life expectancy, but also the world's longest average life span. This study investigated the effect of a novel dual-task (DT) exercise called "Synapsology" (SYNAP), developed as a game-like activity to improve older adults' physical and cognitive functions. Participants (n=24) with a mean age of 70.6 years (65-77 years) were randomly assigned to the SYNAP exercise group (SG, n=15) and the control group (CG, n=9). The SG participated in the DT intervention consisting of 60-minute sessions, twice a week, for 8 weeks. Physical function in timed-up-and-go had significant pre- and post- trial differences (P=0.017) in SG. In addition, cognitive function results in the a 25-hole trail-making peg test (P=0.004) and an oxidative stress marker (P=0.039) had a statistically significant difference within the SG. However, there were no significant differences in the physical and cognitive functions between SG and CG. In the study, older adults who participated in cognitive-motor DT intervention improved significantly with regard to motor ability and cognitive function results. Thus, a game-like DT exercise may help maintain the healthy life of older adults compared to no intervention.

The Association of an Increasing Waist Circumference and Risk of Incident Low Physical Function in Adults with Knee Osteoarthritis

OBJECTIVE

To investigate an 8-year change in waist circumference (WC) with the risk of incident low physical function over 1 year in adults with, or at risk of, knee osteoarthritis (OA).

METHODS

Data from the Osteoarthritis Initiative were used. Change in WC was measured from study enrollment (0 month) to the 96-month visit and classified as Increase (≥ 5cm gain) or Maintain (< 5cm gain). We identified World Health Organization (WHO) risk category based on WC at study enrollment as Large WC (males ≥ 102 cm, females ≥ 88 cm) or Small WC (males < 102 cm, females < 88 cm). The outcome was incident low physical function (≥ 28 Western Ontario and McMaster Universities Osteoarthritis Index physical function subscale) at the 108-month visit. To investigate the association of the 8-year change in WC with the risk of low physical function, we calculated risk ratios (95% CI) and adjusted for potential confounders. We repeated the analyses stratified by the WHO disease risk category.

RESULTS

The Increase WC group had 1.43 (95% CI 1.04-1.96) times the risk of incident low physical function compared to adults in the Maintain WC group. Adults with a Large WC at baseline who increased WC had 1.55 (95% CI 1.00-2.37) times the risk of incident low physical function compared to those who maintained WC. Adults with a Small WC at baseline who increased WC had 1.97 (95% CI 0.84-4.63) times the risk compared to those who maintained WC.

CONCLUSION

Increasing WC increases the risk of incident low physical function in the following year. Maintaining WC may mitigate developing low physical function.

Obstacle-Crossing Task-Related Usual Gait Patterns of Older Adults Differentiating Falls and Gait Ability

Obstacle crossing, such as stepping over a curb, exerts additional demands on balance control, and therefore the study of usual-pace gait patterns associated with obstacle-crossing performance may provide additional insight into understanding falls and deterioration of gait in older adults. Participants included 432 adults aged 60-96 years (218 women). Participants who failed the obstacle-crossing task (n = 181) walked slower with smaller knee range of motion than participants who successfully completed the obstacle-crossing task (all ps < .001). Participants who failed the obstacle crossing reported a greater likelihood of falling in the previous year, more balance problems, lower walking ability, and needed longer time to complete 5 chair stands than those who passed the task (all ps < .05). Obstacle-crossing task may identify gait patterns in older adults who appear functionally intact, but who are nonetheless at risk of fall and balance problems.

Poorer Visual Acuity is Independently Associated With Impaired Balance and Step Length But Not Overall Physical Performance in Older Adults

This study examined the association between varying levels of visual acuity (VA) and physical performance (Short Physical Performance Battery) in older adults. A cross-sectional analysis of participants aged ≥50 years with a clinical diagnosis of vision loss across two studies was undertaken. Of 434 (96%) participants with available VA data, 74% (320/434) had nil, 7% (32/434) had mild, 8% (33/434) had moderate, and 11% (49/434) had severe visual impairment. Poorer VA of both better and worse eye was found to be significantly associated with poorer standing balance (p = .006 and p = .004, respectively); worse VA of the better eye was significantly associated with increased number of steps per meter (p = .005). Mean total Short Physical Performance Battery score of this study population was lower than published normative data for this age group. Physical activity programs for older people with reduced VA should be targeted at improving balance and gait skills to reduce falls risk.

Psychosocial and Health-Related Factors Associated With Discordance Between 13-Year Trajectories of Self-Reported Functional Limitations and Performance-Based Physical Functioning in Old Age

Objective: The objective of this study was to examine correlates of discordance between 13-year trajectories of self-reported functional limitations and performance-based physical functioning in older adults. Method: We included 2,135 participants from the population-based Longitudinal Aging Study Amsterdam, the Netherlands, followed across 1995-2008. Self-reported functional limitations included six (instrumental) activities of daily living. Performance-based functioning was a composite of four tests. We used latent class growth analysis and multinomial logistic regression to examine discordance and its correlates. Results: Patterns of discordance and concordance (41% concordance, 46% "overestimation" of daily functioning, 13% "underestimation") appeared to be persistent over 13 years. Older age, male sex, cognitive impairment, absence of pain, and light alcohol use were associated with overestimation. Younger age, female sex, and lower self-rated health were associated with underestimation. Discussion: Factors associated with overestimation partly differ from those associated with underestimation. Factors that are highly stable over time are particularly good indicators of persistent discordance.

Inter-rater reliability of activity measure for post-acute care '6-Clicks' inpatient mobility short form in the intensive care unit

OBJECTIVE

Examine the inter-rater reliability of the activity measure for post-acute care (AM-PAC) inpatient mobility short form (IMSF) when completed by physical therapists (PTs), during routine clinical practice, in a variety of patients with critical illness.

METHODS

A prospective observational evaluation at single, large academic hospital in the United States. Patients (n = 76) in surgical, medical and neurological intensive care units (ICUs) were evaluated as part of routine clinical practice using the AM-PAC IMSF administered by eight PTs with at least 6 months of experience using this tool. One of two reference rater PTs observed the physical therapy session, and simultaneously scored the AM-PAC IMSF. The reference rater and clinical PTs were blinded to each other's scores with a minimum of 10 assessments completed by each clinical PT. Bland-Altman plots were constructed and intra-class correlation coefficients (ICC) were computed using a random intercept (physical therapy session) model.

RESULTS

Eighty one assessments (five patients assessed twice) were scored by both a clinical PT and reference rater PT (total assessments = 162). Bland-Altman plots revealed a mean difference in AM-PAC IMSF scoring of 0.0 (95% limits of agreement: -3.0 to +3.0), with an ICC (95% confidence interval) of 0.957 (0.947-0.964). The ICC (95% confidence interval) for patients in surgical, medical and neurological ICUs was very similar: 0.949 (0.927-0.959), 0.963 (0.946-0.971) and 0.936 (0.886-0.955), respectively.

CONCLUSIONS

The AM-PAC IMSF demonstrates excellent reliability compared with reference rater PTs when performed by PTs during clinical care across surgical, medical and neurological ICUs.

Effects of Intravenous Golimumab on Health-Related Quality of Life in Patients With Psoriatic Arthritis: 24-Week Results of the GO-VIBRANT Trial

OBJECTIVES

Evaluate the effects of intravenous golimumab 2 mg/kg on multiple domains of health-related quality of life (HRQoL) in adult patients with active psoriatic arthritis (PsA).

METHODS

In this phase III, randomized, double-blinded, placebo-controlled study, adults with active PsA were randomized in a 1:1 ratio to receive intravenous (IV) infusions of placebo (n = 239) or golimumab 2 mg/kg (n = 241) at weeks 0, 4, 12, and 20. Physical function was assessed using the Health Assessment Questionnaire-Disability Index (HAQ-DI). HRQoL was assessed using the 36-item Short-Form Health Survey Physical and Mental Component Summary (SF-36 PCS/MCS) scores, the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue, EQ VAS, and the Dermatology Life Quality Index (DLQI).

RESULTS

Patients in the golimumab group had greater mean changes from baseline in HAQ-DI compared with placebo at weeks 8 (-0.52 vs -0.10), 14 (-0.60 vs -0.12), and 24 (-0.63 vs -0.14). Mean improvements from baseline in SF-36 PCS (8.0 vs 1.7), SF-36 MCS (5.0 vs 1.2), EQ VAS (17.2 vs 3.7), FACIT-Fatigue (7.9 vs 2.0), and DLQI (-7.2 vs -1.7) were also greater in the golimumab group versus placebo at week 8 and were maintained or increased through week 24. Greater proportions of golimumab-treated patients had improvements greater than or equal to the minimal clinically important difference (MCID) for HAQ-DI, SF-36 PCS/MCS, EQ VAS, FACIT-Fatigue, and DLQI scores at weeks 14 and 24.

CONCLUSION

Improvements in HRQoL were greater in the IV golimumab group compared with placebo and were evident at week 8 and sustained through week 24.

Supplementing Glycine and N-acetylcysteine (GlyNAC) in Aging HIV Patients Improves Oxidative Stress, Mitochondrial Dysfunction, Inflammation, Endothelial Dysfunction, Insulin Resistance, Genotoxicity, Strength, and Cognition: Results of an Open-Label Clinical Trial

Background: Patients with HIV (PWH) develop geriatric comorbidities, including functional and cognitive decline at a younger age. However, contributing mechanisms are unclear and interventions are lacking. We hypothesized that deficiency of the antioxidant protein glutathione (GSH) contributes to multiple defects representing premature aging in PWH, and that these defects could be improved by supplementing the GSH precursors glycine and N-acetylcysteine (GlyNAC). Methods: We conducted an open label clinical trial where eight PWH and eight matched uninfected-controls were studied at baseline. PWH were studied again 12-weeks after receiving GlyNAC, and 8-weeks after stopping GlyNAC. Controls did not receive supplementation. Outcome measures included red-blood cell and muscle GSH concentrations, mitochondrial function, mitophagy and autophagy, oxidative stress, inflammation, endothelial function, genomic damage, insulin resistance, glucose production, muscle-protein breakdown rates, body composition, physical function and cognition. Results: PWH had significant defects in measured outcomes, which improved with GlyNAC supplementation. However, benefits receded after stopping GlyNAC. Conclusions: This open label trial finds that PWH have premature aging based on multiple biological and functional defects, and identifies novel mechanistic explanations for cognitive and physical decline. Nutritional supplementation with GlyNAC improves comorbidities suggestive of premature aging in PWH including functional and cognitive decline, and warrants additional investigation.

Effects of exercise therapy on the persistence of physical function, exercise habits, and self-efficacy after cessation of exercise in patients undergoing hemodialysis: A nonrandomized control trial

The present study investigated the sustained effect of exercise therapy discontinuation in patients under hemodialysis with low physical function. Seven subjects in the exercise group and eight in the control group who had low physical function (short physical performance battery; SPPB ≤ 9 points) were included in the study. The exercise group received 6 months of intradialytic exercise, followed by 6 months of observation. We assessed SPPB, grip strength, self-efficacy (SE), and exercise habits in both the groups before and after 12 months. There were statistically significant improvements in SPPB (effect size, 0.58; 95% confidence interval [CI], 0.13-3.55) and SE (effect size, 0.59; 95% CI, 0.25-7.57) in the exercise group relative to the control group. The exercise group displayed more exercise habits than the control group at 12 months. A 6-month period of intradialytic exercise may contribute to the continuation of SPPB and SE after exercise discontinuation.

Effect of Early Mobilization on Physical Function in Patients after Cardiac Surgery: A Systematic Review and Meta-Analysis

The objective effects of early mobilization on physical function in patients after cardiac surgery remain unknown. The purpose of the present study was to clarify the effects of early mobilization on physical function in patients after cardiac surgery through meta-analysis. Four electronic databases were searched on 2 August 2019. We used search keywords related to “early mobilization”, “cardiac surgery”, and “randomized controlled trials”. All randomized controlled trials conducting early mobilization after cardiac surgery were included. We defined early mobilization as the application of physical activity within the first five postoperative days. Citations and data extraction were independently screened in duplicate by two authors. The meta-analysis was conducted using random-effects modeling with EZR software. The primary outcome was the distance walked during the six-minute walking test at hospital discharge. Six randomized controlled trials comprising 391 patients were included following screening of 591 studies. All studies included coronary artery bypass grafting as the cardiac surgery conducted. Early mobilization started on postoperative days 1–2 and was conducting twice daily. Early mobilization showed a trend of being combined with respiratory exercise or psychoeducation. The meta-analysis showed that the distance walked during the 6-min walking test improved by 54 m (95% confidence interval, 31.1–76.9; I² = 52%) at hospital discharge. The present study suggested that early mobilization after cardiac surgery may improve physical function at discharge.

The Association between Health Literacy and Gait Speed in Community-Dwelling Older Adults

The association between gait speed, a vital health outcome in older adults, and health literacy, an important health promotion aspect, is unclear. This study examined the relationship of gait speed with health literacy, physical function, and cognitive function in community-dwelling older adults. The subjects were 240 older adults (52 men, mean age 73.8 ± 6.0 years). Gender, age, and education were self-reported, while height and weight were measured directly. Health literacy was evaluated using Communicative and Critical Health Literacy (CCHL). Grip strength, knee extension strength, toe-grip strength, sit-up test, sit-and-reach test, one-leg stance test time, 30-s chair-stand test (CS-30), and normal gait speed were measured. Subjects were divided into two groups based on normal gait speed—fast (speed ≥ 1.3 m/s) and slow (<1.3 m/s). In the logistic regression analysis, the dependent variable was normal gait speed (fast/slow). Four logistic regression models were utilized to determine whether health literacy affects gait speed. Height and CCHL were found to independently affect gait speed. That health literacy influences gait speed is a new discovery.

Prevalence and determinants of depressive symptoms among adults in Indonesia: A cross-sectional population-based national survey

AIMS

To analyze the association between personal health conditions (self-rated health, physical function, and chronic conditions) and symptoms of depression in Indonesia.

METHODS

Data were collected from the Indonesian family life survey 5. This study used a cross-sectional study design with a sample size of 17,734 respondents. We included depressive symptoms, self-rated health, physical function, chronic conditions, demographics and socioeconomic variables. The center for epidemiologic studies depression scale was used to measure symptoms of depression. Multivariate logistic regression analysis was used to analyze the data.

RESULTS

The results showed that 23.47% of respondents had depressive symptoms, 20.04% had poor self-rated health, 55.93% had a poor physical function, and 32.37% had at least one chronic disease. Respondents who had poor self-rated health, had poor physical function, or had a chronic condition were all had a significantly higher odds of experiencing symptoms of depression after controlling for demographic variables (age, sex, married, and education level), social-economic, and smoking status.

CONCLUSION

Depressive symptoms were significantly associated with personal health conditions including self-rated health, physical functioning, and chronic conditions among community residents. Strategies that can improve personal health conditions needed to be studied at the community level to improve the level of mental health.
