Brognara L, Luna OC, Traina F, Cauli O. Inflammatory Biomarkers and Gait Impairment in Older Adults: A Systematic Review. Int J Mol Sci 2024; 25:1368. [PMID: 38338653 PMCID: PMC10855721 DOI: 10.3390/ijms25031368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 01/15/2024] [Accepted: 01/21/2024] [Indexed: 02/12/2024] Open
Abstract
Peripheral inflammation and gait speed alterations are common in several neurological disorders and in the aging process, but the association between the two is not well established. The aim of this systematic literary review is to determine whether proinflammatory markers are a positive predictor for gait impairments and their complications, such as falls in older adults, and may represent a risk factor for slow gait speed and its complications. The systematic review was performed in line with the Preferred Report Items for Systematic Review and Meta-Analyses (PRISMA). A protocol for literature searches was structured a priori and designed according to the International Perspective Register of Systemic Review (PROSPERO: CRD42023451108). Peer-reviewed original articles were identified by searching seven electronic databases: Excerpta Medica Database (EMBASE), SciVerse (ScienceDirect), Scopus, PubMed, Medline, Web of Science, and the Cochrane Library. The search strategy was formulated based on a combination of controlled descriptors and/or keywords related to the topic and a manual search was conducted of the reference lists from the initially selected studies to identify other eligible studies. The studies were thoroughly screened using the following inclusion criteria: older adults, spatiotemporal gait characteristics, and proinflammatory markers. A meta-analysis was not performed due to the heterogeneity of the studies, and the results were narratively synthesized. Due to the clinical and methodological heterogeneity, the studies were combined in a narrative synthesis, grouped by the type of biomarkers evaluated. A standardized data extraction form was used to collect the following methodological outcome variables from each of the included studies: author, year, population, age, sample size, spatiotemporal gait parameters such as gait velocity, and proinflammatory markers such as TNF-α, high sensitivity C-reactive (CRP) proteins, and IL-6. We included 21 out of 51 studies in our review, which examined the association between inflammatory biomarkers and gait impairment. This review highlights the role of TNF-α, CRP, and IL-6 in gait impairment. Biomarkers play an important role in the decision-making process, and IL-6 can be an effective biomarker in establishing the diagnosis of slow gait speed. Further longitudinal research is needed to establish the use of molecular biomarkers in monitoring gait impairment.

Abstract
BACKGROUND Few studies have compared gait speed and its correlates among different ethnogeographic regions. The goals of this study were to describe usual and rapid gait speed, and identify their correlates across Australian, Asian, and African countries. METHODS We used data from 6 population-based cohorts of adults aged 65+ from 6 countries and 3 continents (N = 6 472), with samples ranging from 231 to 1 913. All cohorts are members of the Cohort Studies of Memory in an International Consortium collaboration. We investigated whether clinical (body mass index [BMI], hypertension, stroke, apolipoprotein status), psychological (cognition, mood, general health), and behavioral factors (smoking, drinking, physical activity) correlated with usual (N = 4 cohorts) and rapid gait speed (N = 3 cohorts) similarly across cohorts. Regression models were controlled for age, sex, and education, and were sex-stratified. RESULTS Age- and sex-standardized usual gait speed means ranged from 0.61 to 1.06 m/s and rapid gait speed means ranged from 1.16 to 1.64 m/s. Lower BMI and better cognitive function consistently correlated with faster gait speed in all cohorts. Less consistently, not having hypertension and greater physical activity engagement were associated with faster gait speed. Associations with mood, smoking, and drinking were largely nonsignificant. These patterns were not attenuated by demographics. There was limited evidence that the associations differed by sex, except physical activity, where the greater intensity was associated with usual gait among men but not women. CONCLUSIONS This study is among the first to describe the usual and rapid gait speeds across older adults in Africa, Asia, and Australia.

Ahmed-Yousef NS, Dilian O, Iktilat K, Agmon M. CRP, but not fibrinogen, is associated with gait speed as early as middle age, in females but not males. Sci Rep 2023; 13:15571. [PMID: 37730750 PMCID: PMC10511512 DOI: 10.1038/s41598-023-42183-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Accepted: 09/06/2023] [Indexed: 09/22/2023] Open
Abstract
Low grade systemic inflammation and age-related gait speed decline are known to be related in older adults, but their relations in the early stages of the aging process are yet to be fully described. The aim of this study was to examine the relationship between gait speed and two inflammation markers-c-reactive protein (CRP) and fibrinogen-in a cohort of middle-aged adults in Israel. 326 healthy, middle-aged, Muslim-Arabs from three villages in northern Israel participated in this cross-sectional study. Serum CRP and fibrinogen were measured via blood tests, and gait speed was assessed with the 6-min walk test (6MWT). After adjusting for sex, age, height, BMI, systolic blood pressure, fasting blood glucose and triglycerides, executive function, smoking status and aerobic physical activity, gait speed was negatively and significantly associated with CRP (b = - 0.01, p = 0.029). When stratifying by gender, this link remained significant only among females (b = - 0.012, p = 0.041), such as that an increase of one SD unit of CRP was associated with a 0.047 m/s decrease in gait speed. No significant link was found between fibrinogen levels and gait speed. Blood CRP levels are associated with a slower walking speed already in middle age, independent of age, executive function and cardio-metabolic factors, among female Arab-Muslims in Israel. Future studies should examine this relationship longitudinally and investigate a broader array of inflammation markers. Systemic inflammation may serve as an early marker for people at risk of decreased walking or accelerated aging; Early identification and intervention among at-risk individuals may help prevent or slow gait speed decline, and promote healthier aging.

Abstract
This study explored the potential relationship between levels of high-sensitivity C-reactive protein (hs-CRP) in plasma and freezing of gait (FOG) in Parkinson's disease (PD) in China. A total of 72 healthy subjects, 62 PD patients with FOG, and 83 PD patients without FOG from our center were enrolled in this prospective study. Patients with FOG showed significantly higher hs-CRP levels than controls, but patients without FOG did not. Binary logistic regression analysis identified levels of hs-CRP in plasma to be an independent risk factor for FOG among the patients in our cohort (OR 6.371, 95% CI 2.589-15.678, p < 0.001). In fact, a cut-off level of 0.935 mg/L distinguished patients with or without FOG [area under the ROC curve (AUC) = 0.908, sensitivity 87.1%, specificity 89.2%]. Our study suggests that high levels of hs-CRP in plasma are associated with the occurrence of FOG in PD. The pooled data combined with a previous study carried out in Spain also indicate a positive association between plasma hs-CRP levels and FOG in PD. However, more research is still needed to verify the plasma hs-CRP as a potential biomarker of FOG.

Abstract
Background Gait speed, a central marker of aging, has been linked to various health outcomes, such as cognitive and physical functions in middle-aged adults. Although long-term systemic low-grade inflammation is considered a mechanism underlying a variety of aging-related risk factors, the longitudinal associations between inflammation markers and gait speed are yet to be fully investigated. Objective To explore the associations of CRP and fibrinogen levels, measured two decades ago, with gait speed among community dwelling adults, considering the contribution of cardio-metabolic factors and cognition. Methods Study participants took part in two phases of the of the “Kibbutzim Family Study” (i.e., Phase II, 1999–2000 and Phase III, 2017–2019). Blood samples collected in Phase II (baseline) were used to determine level of inflammatory markers. Gait speed was assessed under single-task (ST) and dual-task (DT) conditions in Phase III. Demographic, anthropometric and clinical data were collected in both phases. Linear regression models were used to assess the adjusted associations of inflammation and gait speed. Results A total of 373 individuals aged 34–99 (mean 64 ± 13 years) in Phase III were included in the study. Gait speed under ST was negatively associated with baseline levels of fibrinogen (b per standard deviation (SD) = −0.053, p = 0.0007) and CRP (b per SD = −0.043, p = 0.010), after adjusting for baseline and concurrent cardiometabolic risk factors. Accounting for executive functions, associations of fibrinogen with gait under ST were somewhat attenuated, yet associations remained statistically significant (p < 0.05). Associations with CRP were attenuated to the null. In contrast, there were no associations between inflammation markers and gait under DT. Conclusion Our findings demonstrate that in a sample including younger to older adults, higher systemic inflammatory activity was linked with gait 20 years later, beyond age and cardiometabolic health, and to a certain extent, beyond executive functions. Thus, systemic inflammation may serve as an early marker to identify individuals at risk for gait decline.

Abstract
BACKGROUND This study aims to investigate the predictive value of biological and neuroimaging markers to determine incident frailty among older people for a period of 5 years. METHODS We included 1394 adults aged 70 years and older from the Multidomain Alzheimer Preventive Trial, who were not frail at baseline (according to Fried's criteria) and who had at least 1 post-baseline measurement of frailty. Participants who progressed to frailty during the 5-year follow-up were categorized as "incident frailty" and those who remained non-frail were categorized as "without frailty." The differences of baseline biochemical factors (25-hydroxyvitamin D, homocysteine, omega-3 index, C-reactive protein), other biological markers (Apolipoprotein E genotypes, amyloid-β deposits), and neuroimaging data (gray matter volume, hippocampal volume, white matter hyperintensities) were compared between groups. Cox proportional hazard model was used to evaluate the associations between biomarkers and incident frailty. RESULTS A total of 195 participants (14.0%) became frail over 5 years. Although 25-hydroxyvitamin D deficiency, homocysteine levels, low-grade inflammation (persistently increased C-reactive protein 3-10 mg/L), gray matter, and hippocampal volume were significantly associated with incident frailty in unadjusted models, these associations disappeared after adjustment for age, sex, and other confounders. Omega-3 index was the sole marker that presented a trend of association with incident frailty (hazard ratio: 0.92; 95% confidence interval: 0.83-1.01; p = .082). CONCLUSIONS This study failed to identify biomarkers able to predict frailty incidence in community-dwelling older adults for a period of 5 years. Further longitudinal research with multiple measurements of biomarkers and frailty is needed to evaluate the long-term relationships between changes in biomarkers levels and frailty evolution.

Abstract
OBJECTIVES The motoric cognitive risk (MCR) syndrome, characterized by cognitive complaints and slower gait speed, is a pre-dementia syndrome associated with dementia and mortality risk. The present study examined whether subjective age, that is how old or young individuals feel relative to their chronological age, is related to concurrent and incident MCR syndrome. A relation between subjective age and MCR will inform knowledge on psychological factors related to dementia risk, identify who is at greater risk, and suggest a potential target of intervention. METHOD The study sample was composed of 6,341 individuals aged 65 to 107 years without dementia from the Health and Retirement Study (HRS), a longitudinal study of adults aged 50 years and older. Participants completed measures of subjective age, cognitive complaints, and gait speed and provided information on demographic factors, cognition, physical activity, depressive symptoms, and body mass index (BMI) at baseline in 2008/2010. Incident MCR was assessed four and eight years later. RESULTS Controlling for demographic factors, an older subjective age was related to more than 60% higher likelihood of MCR at baseline and to around 50% higher risk of incident MCR over time. These associations remained significant when cognition, physical inactivity, depressive symptoms, and BMI were included in the analytic models. CONCLUSION This study provides evidence that how old individuals feel is related to concurrent and incident MCR beyond the effect of chronological age, other demographic factors, physical inactivity, depressive symptoms, BMI, and cognitive functioning.

Abstract
BACKGROUND Whereas the independent effects of biomarkers, including 25-hydroxy vitamin D (25(OH)D), insulin-like growth factor 1, C-reactive protein, and interleukin 6 (IL-6), on gait speed in older adults have been evaluated, their joint effects on gait speed are not well understood. METHODS Study subjects aged at least 65 at baseline (N = 970) were enrolled in the population-based Invecchiare in Chianti (InCHIANTI) study from 1998 to 2000 and were followed up at 3 and 6 years. All above biomarkers and gait speed data were measured at each of the three time points. Using a generalized estimating equation approach, we determined if slow gait speed (<0.8 m/s) was associated with the biomarkers. Further investigation was conducted for interactions between high IL-6 (≥.87 pg/mL) and other biomarkers focusing on low 25(OH)D (<20 ng/mL). RESULTS After controlling for other biomarkers and potential confounders, IL-6 emerged as the only biomarker independently associated with gait speed. The association between high IL-6 and slow gait speed was enhanced by low 25(OH)D, with significant interaction between high IL-6 and low 25(OH)D (p = .038). The odds ratio of slow gait speed for low 25(OH)D and high IL-6 was 1.63 (95% confidence interval [CI]: 1.15, 2.32) compared with the reference groups with both biomarker levels at the other ends. CONCLUSION The association of low vitamin D with slow gait speed statistically interacts with high IL-6. Coexisting vitamin D insufficiency and inflammation may provide a better biomarker for identifying those at risk of developing impairments in gait speed than either factor alone.

Abstract
BACKGROUND Gait speed is a strong predictor of morbidity and mortality in older adults. Understanding the factors associated with gait speed and the associated adverse outcomes will inform mitigation strategies. We assessed the potentially modifiable and nonmodifiable factors associated with gait speed in a large national cohort of middle and older-aged Canadian adults. METHODS We examined cross-sectional baseline data from the Canadian Longitudinal Study on Aging (CLSA) Comprehensive cohort. The study sample included 20 201 community-dwelling adults aged 45-85 years. The associations between sociodemographic and anthropometric factors, chronic conditions, and cognitive, clinical, and lifestyle factors and 4-m usual gait speed (m/s) were estimated using hierarchical multivariable linear regression. RESULTS The coefficient of determination, R 2, of the final regression model was 19.7%, with 12.9% of gait speed variability explained by sociodemographic and anthropometric factors, and nonmodifiable chronic conditions and 6.8% explained by potentially modifiable chronic conditions, cognitive, clinical, and lifestyle factors. Potentially modifiable factors significantly associated with gait speed include cardiovascular conditions (unstandardized regression coefficient, B = -0.018; p < .001), stroke (B = -0.025; p = .003), hypertension (B = -0.007; p = .026), serum Vitamin D (B = 0.004; p < .001), C-reactive protein (B = -0.005; p = .005), depressive symptoms (B = -0.003; p < .001), physical activity (B = 0.0001; p < .001), grip strength (B = 0.003; p < .001), current smoking (B = -0.026; p < .001), severe obesity (B = -0.086; p < .001), and chronic pain (B = -0.008; p = .018). CONCLUSIONS The correlates of gait speed in adulthood are multifactorial, with many being potentially modifiable through interventions and education. Our results provide a life-course-perspective framework for future longitudinal assessments risk factors affecting gait speed.

Lifetime Duration of Exposure to Biomechanical Factors at Work as a Mediator of the Relationship Between Socioeconomic Position and Walking Speed. Front Public Health 2020; 8:412. [PMID: 33282805 PMCID: PMC7689267 DOI: 10.3389/fpubh.2020.00412] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2019] [Accepted: 07/10/2020] [Indexed: 11/13/2022] Open
Abstract
The study aimed to assess the proportion mediated by the duration of exposure to ergonomic factors at work on the relationship between socioeconomic position (SEP) and low walking speed. This cross-sectional study was performed on data collected at baseline on 19,704 men and 20,273 women 45-70 years old, currently or previously employed, enrolled in the Constances cohort. SEP was assigned through current or last occupation, categorized in three classes, based on the European Socioeconomic Classification. Walking speed was assessed through one measurement of normal walking for 3 m and dichotomized at the lowest quintile of the sex- and age- (5-year) specific distribution. Self-reported workplace exposure throughout working life to repetitive work, intense physical work, and lifting/carrying heavy loads was used to assess the duration of exposure to each factor, categorized in four classes. Through Poisson regression models, adjusted for BMI, smoking, alcohol intake, hypertension, physical activity, diabetes, cardiovascular diseases, and a cognitive score, the attenuation in the prevalence ratio (PR) of low walking speed by SEP produced by the inclusion of duration of exposure to each factor was evaluated. The mediating effect of work ergonomic exposures on the relationship between SEP and low walking speed was assessed using the weighted method by Vanderweele. In the fully adjusted model without ergonomic exposures, both men and women in the middle and the lowest SEP had a significantly increased risk of low walking speed compared with those in the highest SEP (men: PR = 1.30 and PR = 1.46, respectively; women: PR = 1.24 and PR = 1.45, respectively). The inclusion in separate regression models of exposure duration to repetitive work, intense physical work, and handling of heavy loads produced modest risk attenuations in both men and women, all smaller or around 10%. Mediation analysis revealed in both sexes significant mediation effects for most ergonomic exposures considered, although also with low mediation effects. Significant differences in walking speed by SEP were observed in this large sample, but the proportion of such differences explained by the duration of exposure to ergonomic factors at work was low using either the risk attenuation or the mediation analysis methods.

Abstract
CONTEXT The associations between serum 25-hydroxyvitamin D concentrations [25(OH)D] and all-cause mortality have been inconsistent in existing literatures. One plausible reason is the interaction of intrinsic vitamin D with other biological conditions such as malnutrition and chronic inflammation. OBJECTIVE To explore the associations between serum levels of 25(OH)D, albumin, and all-cause mortality and further evaluate their interactions in elderly people. DESIGN Population-based longitudinal study. SETTING AND PARTICIPANTS Data were obtained from 1834 people aged 65 to 112 who had their serum 25(OH)D and albumin assayed at baseline in 2011. Participants' survival status was ascertained at the 2014 and 2018 follow-up survey waves. MAIN OUTCOME MEASURES All-cause mortality. RESULTS Among the 1834 participants, both serum 25(OH)D and albumin concentrations were inversely associated with all-cause mortality (Ps < 0.001). In addition, the interaction effect of 25(OH)D and albumin on all-cause mortality was observed among the participants (P = 0.001). In the group with a higher albumin level (≥40 g/L), participants with a lower level of 25(OH)D (<50 nmol/L) had higher risk of mortality than their counterparts (hazard ratio, 1.92; 95% confidence interval, 1.45-2.56), and the association was more pronounced in women. In the group with a lower albumin level (<40 g/L), the associations failed to reach statistical significance in all participants as well as in women and in men. CONCLUSIONS Serum 25(OH)D and albumin levels were inversely associated with all-cause mortality in Chinese older adults. The association between 25(OH)D and mortality was more pronounced in participants with higher albumin levels.

Abstract
Background: Vitamin D and complement components shared some common pathophysiological pathways in the musculoskeletal system, circulation, and metabolism, which were linked to physical function. It is hypothesized that serum complement components may interact with vitamin D in respect of the physical activities of daily living (PADLs). Objective: To investigate if serum complement components 3 (C3), complement components 4 (C4), and 25-hydroxyvitamin D [25(OH)D] associate with PADLs, and to examine whether the association between 25(OH)D levels and PADLs varies at different complement component levels among Chinese centenarians. Methods: This study was conducted in a group of population-based centenarians. PADLs were evaluated using the Barthel Index. Multiple regressions were used to analyze the associations among 25(OH)D, complements C3 and C4, and PADLs. Results: Among 943 participants, 672 (71.3%) had physical dependence (PD). After adjusting for potential confounders, serum 25(OH)D and C3 levels were positively correlated with PADLs, while C4 levels were negatively correlated with PADLs (Ps < 0.05). Serum 25(OH)D levels significantly interacted with both C3 (P for interaction = 0.033) and C4 (P for interaction = 0.006) levels on PADLs. At lower complement component levels, the multivariate odds ratios (ORs) of the upper tertile of vitamin D for PD were 0.32 (95% CI: 0.18-0.55) in the C3 group and 0.29 (95% CI: 0.16-0.50) in the C4 group. At higher complement component levels, the ORs in the C3 and C4 groups were not statistically significant. Conclusions: In a group of population-based Chinese centenarians, we observed that serum complement C3 and 25(OH)D levels were positively associated with PADLs, while C4 was negatively associated with PADLs. The associations between 25(OH)D levels and PADLs were more pronounced in groups with lower serum complement component levels.

Abstract
Dementia is characterized by a long preclinical phase that may last years to decades before the onset of mild cognitive impairment. Slow gait speed and subjective memory complaint commonly co-occur during this preclinical phase, and each is a strong independent predictor of cognitive decline and dementia. Motoric cognitive risk (MCR) syndrome is a pre-dementia syndrome that combines these two early harbingers of dementia. The risk of cognitive decline or dementia is stronger for MCR than for either slow gait speed or subjective memory complaint alone. Slow gait speed and subjective memory complaint have several common risk factors: cardiovascular disease, diabetes mellitus, abnormal cortisol profiles, low vitamin D levels, brain atrophy with decreased hippocampal volume, and increased deposition of beta-amyloid in the brain. The underlying pathogenesis of MCR remains poorly understood. Metabolomics and proteomics have great potential to provide new insights into biological pathways involved in MCR during the long preclinical phase preceding dementia.

Abstract
C-reactive protein (CRP) is a biomarker of systemic inflammation that has been linked to accelerated decline in walking speed in older adults. The aim of the present study was to compare the CRP levels of PD patients with vs patients without freezing of gait (FOG). Patients and controls participating in the COPPADIS-2015 study that performed blood extraction for determining molecular serum biomarkers were included. Patients with FOG were identified as those with a score of 1 or greater on item-3 of the Freezing of Gait Questionnaire (FOG-Q). Immunoassay was used for determining ultrasensitive CRP (US-CRP) level (mg/dL). In the PD group (n = 225; 61.8 ± 9.5 years old, 61.8% males), 32% of the patients presented FOG but none in the control group (n = 65; 60.3 ± 6.1 years old, 56.9% males) (p < 0.0001). Differences in US-CRP level were significant in patients with FOG vs patients without FOG and vs controls (0.31 ± 0.52 vs 0.16 ± 0.21 vs 0.21 ± 0.22; p = 0.04). Significant differences were also observed between patients with vs without FOG (p = 0.001) but not between patients and controls (p = 0.163). US-CRP level was related to FOG (OR = 4.369; 95% CI 1.105-17.275; p = 0.036) along with H&Y (OR = 2.974; 95% CI 1.113-7.943; p = 0.030) and non-motor symptoms burden (NMSS total score; OR = 1.017; 95% CI 1.005-1.029; p = 0.006) after adjusting for age, gender, disease duration, equivalent daily levodopa dose, number of non-antiparkinsonian drugs per day, motor fluctuations, cognition, motor phenotype, and chronic use of anti-inflammatory drugs. The present study suggests that serum US-CRP level is related to FOG in PD patients. Inflammation could be linked to FOG development.

Abstract
Objectives The association of C‐reactive protein (CRP) and serum 25‐hydroxyvitamin D [25(OH)D] and cardiovascular disease (CVD) remains unknown. Methods We performed a cross‐sectional analysis on 3848 participants by using the data from the National Health and Nutrition Examination Surveys (2007 to 2008). CVD was defined as a compromise of stroke, myocardial infarction, heart failure, and coronary heart disease. High CRP was defined as ≥0.2 mg/dL, and vitamin D status were categorized as severe deficiency, <25 nmol/mL; deficiency, 25 to 49.9 nmol/mL; insufficiency, 50 to 74.9 nmol/mL; and normal, ≥75 nmol/mL. Statistical analysis was performed using logistic regression models. Results We found that both high CRP and low 25(OH)D levels were associated with CVD. Participants with high CRP levels and severe vitamin D deficiency had a higher likelihood of having CVD than those with neither risk factor (odds ratio = 2.69, 95% confidence interval = 1.45‐4.98, P = .0017). In stratified analysis, a significant positive association between vitamin D level and CVD was observed only in the high CRP group. However, in the absence of high CRP, even with severe vitamin D deficiency, no association was found with an increasing risk of CVD (P = .6416). Conclusion Within a cross‐sectional, nationally representative sample, these findings suggest that vitamin D status evaluation, or vitamin D supplement may be especially important for individuals with high CRP levels.

Functional capacity, renal function and vitamin D in community-dwelling oldest old. Int Urol Nephrol 2019; 51:713-721.

Abstract
PURPOSE The aim of this study was to evaluate the association between the decline in estimated glomerular filtration rate (eGFR) and serum 25(OH)D with the physical and mental functional capacity of elderly individuals aged 80 years or older. METHODS We evaluated the functional capacity in its multidomain aspects: Geriatric Depression Scale (GDS), Instrumental Activities of Daily Living (IADL), Mental State Mini-Exam (MMSE), Verbal Fluency Test (VF), handgrip strength and time to sit and rise from a chair five times, combined creatinine and cystatin C-based eGFR and 25(OH)D levels in 205 independent asymptomatic and community-dwelling elderly subjects in a cross-sectional study. RESULTS Every 1 year of life, there was reduction of about 10% chance of adequate performance in functional capacity. Each 1 ml/min/m2 in eGFR was associated with 2% better chance of adequate performance in the IADL. We found no association between eGFR and cognition. Serum 25(OH)D between 15.00 and 22.29 ng/ml increased the chance of better performance in VF, IADL, handgrip strength and sit and rise from the chair compared to the lower level of serum vitamin D. CONCLUSIONS Decreased renal function associated with age compromises the ability to perform activities for independent life in the community, but we did not observe influence in specific domains of cognition and physical performance. Low serum level of 25(OH)D appears to be a marker of greater risk of functional decline than eGFR measurement in independent oldest old dwelling in the community.

Abstract
The present study aims to clarify the association of vitamin D status with functionality, measured through gait speed and hand grip strength, in a sample of older adults, considering sex-specific characteristics and the potential confounding effect of lifestyle factors, disease, skin phenotype, season of blood collection and vitamin D supplementation. The Nutrition UP 65 cross-sectional study was conducted in a population-based sample of 1,425 older adults ≥ 65 years old. Serum levels of 25-hydroxyvitamin D were quantified through electrochemiluminescence immunoassay. Multinomial logistic regressions were carried out using quartiles of gait speed and of hand grip strength as dependent variables. Participants at risk of vitamin D inadequacy (30.0-49.9 nmol/L) and deficiency (< 30.0 nmol/L) presented higher adjusted odds ratio of the lowest values of gait speed and hand grip strength than those with adequate vitamin D levels (≥ 50.0 nmol/L). These associations were strongest among men at risk of vitamin D deficiency [adjusted odds ratio for the lowest quartile of gait speed = 3.24; 95% CI: 1.56–6.73 and for the lowest quartile of hand grip strength = 3.28; 95% CI: 1.47-7.31] than in women at risk of vitamin D deficiency [adjusted odds ratio for the lowest quartile of gait speed = 2.72; 95% CI: 1.37-5.41 and for the lowest quartile of hand grip strength = 1.56; 95% CI: 0.81–3.00]. In conclusion, in older adults, particularly in men, the risk of vitamin D deficiency was directly associated with the lowest values of gait speed and of hand grip strength. However, randomized controlled trials are needed to overcome the possibility of reverse causation and residual confounding. Present results emphasise the need for strategies to promote the reduction of the high prevalence of low vitamin D status among the Portuguese older adult population.

Abstract
AIM To explore vitamin D and the risk factors associated with knee pain in a representative population of Korean older adults METHODS: Data were analyzed from the Korean National Health and Nutrition Examination Survey (2010-2013). A total of 3874 participants (1728 men, 2146 women) aged 65 years and older who had a measured serum 25-hydroxyvitamin D level were evaluated. Multivariate logistic regression was used to investigate the relationship between serum vitamin D and knee pain severity RESULTS: Sex, age, obesity, education, knee radiographic osteoarthritis, hip pain and back pain were associated with having knee pain. Also, the level of serum 25-hydroxyvitamin D was not significantly associated with knee pain severity. After controlling for confounding factors, the level of serum 25-hydroxyvitamin D was not significantly associated with knee pain, and severity levels of mild, moderate and severe. CONCLUSIONS The results show that the serum vitamin D did not have a significant effect on knee pain in older adults in Korea. Geriatr Gerontol Int 2017; 17: 1278-1285.

Abstract
BACKGROUND Low gait speed is associated with inflammation and muscle strength. Follistatin, a glycosylated plasma protein, is involved in inflammatory diseases, bone metabolism, muscle strength and cognition. However, research regarding the relationship between follistatin and gait speed in elderly individuals is limited. In this study, we aimed to examine the association between follistatin and gait speed in older adults. METHODS This cross-sectional, observational study included 205 ambulatory individuals aged ≥ 65 years. The baseline measures included 15-foot walking time, a structured questionnaire, grip strength and biomarkers, including follistatin and myostatin levels. Multiple linear regression was used to determine the change in gait speed for each 1 pg/mL increase in serum follistatin level. An extended model approach with a quartile-based analysis of serum follistatin levels was conducted. RESULTS In the linear regression model, the β coefficient, representing the change in gait speed for each 1 pg/mL increase in serum follistatin level, was -0·308 (P < 0·001). After additional adjustment for relevant covariates, the β coefficient changed slightly, although the negative correlation remained (all P ≤ 0·001). After controlling for multiple covariates, participants in the highest serum follistatin level quartile had a significantly lower gait speed than those in the lowest quartile (all P for trend < 0·001). CONCLUSIONS A higher follistatin level was independently associated with lower gait speed in community-dwelling elderly individuals; this suggests that serum follistatin level may be an indicator of mobility in elderly persons and may more particularly represent lower extremity function.

Abstract
Cardiovascular disease and frailty frequently occur together. Both are associated with inflammation, which may be partially triggered by oxidative stress, especially in cardiovascular disease. We investigated whether inflammatory and oxidative stress biomarkers linked to cardiovascular disease were associated with frailty and the related outcome of gait speed. We report cross-sectional associations of biomarkers and frailty assessed at Framingham Offspring Study cycle eight. Participants ≥60 years were eligible if they had information on frailty and at least one of the following: C-reactive protein, interleukin-6, tumor necrosis factor receptor 2, 8-epi-FGFα isoprostanes (isoprostanes), lipoprotein phospholipase A2 (LpPLA2) mass or activity, osteoprotegerin, intracellular adhesion molecule-1, monocyte chemoattractant protein-1 or P-selectin. Stepwise logistic models were utilized for frailty and stepwise linear models for gait speed. Covariates included age, sex, body mass index, smoking, and co-morbidities. Odds ratios (ORs) and slope estimates (B) are reported per standard deviation increase of loge-transformed biomarker. Of the 1919 participants, 142 (7 %) were frail. In a stepwise model, frailty odds increased with higher interleukin-6 (OR 1.90, 95 % CI 1.51, 2.38), isoprostanes (OR 1.46, 95 % CI 1.12, 1.92), and LpPLA2 mass (OR 1.29, 95 % CI 1.00, 1.65). Stepwise regression found that slower gait speeds were associated with interleukin-6 (B = -0.025 m/s, 95 % CI 0.04, -0.01), isoprostanes (B = -0.019, 95 % CI -0.03, -0.008), LpPLA2 mass (B = -0.016, 95 % CI -0.03, -0.004), and osteoprotegerin (B = -0.015, 95 % CI -0.03, -0.002, all p < 0.05). Interleukin-6, isoprostanes, and LpPLA2 mass were associated with greater frailty odds and slower gait speeds. Oxidative stress may be a mechanism contributing to frailty.

Abstract
PURPOSE OF REVIEW With the discovery and widespread use of antiretroviral therapies, growing numbers of individuals with HIV are now able to live into advanced age. Nevertheless, growing evidence indicates that these dramatic gains in longevity have also resulted in increased prevalence among the survivors of non-AIDS morbidity and disability, together with acceleration of many underlying aging processes. As a result, individuals involved in HIV care, policy, and research have increasingly had to refocus their efforts from a traditional infectious disease emphasis toward conceptual models grounded in the management of common chronic diseases and geriatric syndromes. RECENT FINDINGS It has been estimated that by 2015, one-half of all Americans with HIV will be 50 years or older. Such individuals are likely to develop chronic diseases typically seen in their older HIV-negative counterparts. Moreover, the presence of multiple coexisting chronic conditions together with polypharmacy and acceleration of varied age-related physiological changes renders many older HIV-positive individuals more vulnerable to becoming disabled or dying from conditions that are not immediately linked to HIV. SUMMARY As growing numbers of individuals confront the prospect of a life with HIV, both they and their providers will need to shift their focus toward a broader and more encompassing perspective that considers the impact of multiple coexisting conditions and age-related changes on outcome measures associated with function, independence, and quality of life. To that end, there is an urgent need for increased dialog between different disciplines, ensuring that the care of older HIV-positive individuals is guided by research that incorporates relevant functional outcome measures.
