RESUMO
BACKGROUND: Vitamin D deficiency is frequent in older adults and associated with poor musculoskeletal function. The prevalence of pre-frailty is also high in older persons, who may proceed to a frail state. This study aimed to determine the vitamin D levels in pre-frail older adults and its correlation with hand grip strength. METHODS: A cross-sectional study was conducted on older adults (age > 60 years) with a pre-frail condition who were visiting the outpatient geriatric clinic at Cipto Mangunkusumo Hospital in Jakarta, Indonesia. Serum levels of vitamin D, measured as 25(OH)D, were determined by enzyme-linked immunosorbent assay (ELISA), and hand grip strength was measured using a Jamar hydraulic dynamometer. Correlations between vitamin D levels and hand grip strength were evaluated by Spearman's rank correlation coefficient. Multiple linear regression analysis was carried out to assess contribution of variables that influence hand grip strength. RESULTS: Of 95 pre-frail older adults (mean age 70.08 ± 5.35 years), 67.4% were female, and the median vitamin D level was 17.91 (interquartile range/IQR 13.68-26.36) ng/mL. Overall, 11.6% of the participants had normal vitamin D levels, whereas 34.7% and 53.7% had insufficient and deficient levels, respectively. Females were more likely to have inadequacy of vitamin D than males. Those with vitamin D deficiency tended to have a higher body mass index (BMI) and lower vitamin D intake than normal levels. A significant correlation between serum vitamin D levels and hand grip strength was observed (r = 0.283; P = 0.006). After adjusting for age, comorbidities, nutritional status, functional status, BMI, protein intake, and sun exposure score, regression analysis between hand grip strength and vitamin D levels gave standard coefficient beta = 0.255 (P = 0.013). CONCLUSION: In this study, pre-frail older adults had a high proportion of deficient and insufficient vitamin D levels, and a significant correlation was found between serum vitamin D levels and hand grip strength.
RESUMO
BACKGROUND: obesity and osteoarthritis have strong inter-relationship with multi-factorial mechanism that caused pain and leads to decreased quality of life. Exercise has been identified as prevention and management against obesity and joint pain. This systematic review aims to assess the effect between exercises compared to diet group for chronic pain management, physical and mental function in obese patients with chronic musculoskeletal problem. METHODS: we performed a systematic search of Randomized Control Trial studies from Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EBSCO; SCIENCEDIRECT (Elsevier); SCOPUS, grey literature, trial registry, ongoing study for published studies, and from the ClinicalTrial.gov, thesis of rehabilitation medicine in RSCM, and proceeding books for unpublished studies that was last updated on November 2016. Risk of bias was assessed using Cochrane risk-of-bias tool and data were analyzed using Review Manager 2014. RESULTS: one study showed no difference in pain reduction (assessed using VAS) between two groups. Two studies showed improvement in physical function measured using 6MWT in exercise group at 6 and 18 months with mean difference 28.12 [11.20, 45.04] and 26.21 [9.01, 43.41]. There was no significant effects observed for Mental and Physical Function based on SF-36 after 6 months (1 study) and 18 months (2 studies) observation, with mean difference 1.10 [-0.79, 2.99] and 0.08 [-1.53, 1.70] respectively for Mental Function score and -0.30 [-2.54, 1.94] and -0.36 [-2.30, 1.57] respectively for Physical Function score. CONCLUSION: exercise can improve physical function objectively, but could not reduce pain in obese patients with chronic musculoskeletal problem subjectively.

BACKGROUND: sarcopenia contributes to the development of frailty syndrome. Frailty syndrome is potentially improved by modifying insulin resistance, inflammation, and myostatin level. This study is aimed to investigate the effect of metformin on handgrip strength, gait speed, myostatin serum level, and health-related quality of life (HR-QoL) among non-diabetic pre-frail elderly patients. METHODS: a double blind randomized controlled trial study was conducted on non-diabetic elderly outpatients aged ≥ 60 years with pre-frail status based on phenotype and/ or index criteria (Cardiovascular Health Study and/ or Frailty Index 40 items) consecutively recruited from March 2015 to June 2016 at Cipto Mangunkusumo Hospital. One-hundred-twenty subjects who met the research criteria were randomized and equally assigned into 3 x 500 mg metformin or placebo group. The study outcomes were measured at baseline and after 16 weeks of intervention. RESULTS: out of 120 subjects, 43 subjects in metformin group and 48 subjects in placebo group who completed the intervention. There was a significant improvement on the mean gait speed of metformin group by 0.39 (0.77) second or 0.13 (0.24) meter/second that remained significant after adjusting for important prognostic factors (p = 0.024). There was no significant difference on handgrip strength, myostatin serum level, and HR-QoL between both groups. CONCLUSION: 3 x 500 mg metformin for 16 weeks was statistically significant and clinically important in improving usual gait speed as one of the HR-QoL dimensions, but did not significantly improve the EQ-5D index score, handgrip strength, nor myostatin serum level.

AIM: to get a recommendation on the best frailty syndrome diagnostic tools, that will be able to be practiced on a daily setting in Indonesia. METHODS: this is a cross-sectional study with diagnostic test approach, conducted to patients in the Geriatric Outpatient Clinic of Cipto Mangunkusumo National Referral Hospital on May-June 2013. Each subject underwent a frailty evaluation using CHS, SOF, FI-CGA and FI-40 scoring systems. Then, we calculate the sensitivity, specificity, PPV, NPV, LR+ and LR- of each scoring system compared to FI-40. RESULTS: the proportion of frail, pre-frail and fit according to FI-40 are 25.3%, 71% and 3.7% respectively. In terms of differentiation frail to non-frail, CHS had 41.2% sensitivity, 95% specificity, PPV 73.7%, NPV 82.7%, LR+ 8.41 and LR- 0.62. SOF scoring system had 17.6% sensitivity, 99.5% specificity, PPV 92.3%, NPV 78.1%, LR+ 35.2 and LR- 0.83. Furthermore FI-CGA had 8.8% sensitivity, 100% specificity, PPV 100%, NPV 76.4%, LR+ and LR- 0.91. CONCLUSION: There is no better scoring system that could be implemented to screen for frailty syndrome other than FI-40 items. However, other scoring systems could be used as a good diagnostic tool for the syndrome.

AIM: to design a model and assess the effectiveness of endurance exercise to increase physical fitness in intelectual disability (ID) patients with obesity. METHODS: a randomized-controlled clinical trial was performed in ID patients with obesity aged 10-30 years old from all Special School in DKI Jakarta, which were randomly allocated into 3 groups and then given 3 different type of exercises: lower extremity muscles endurance exercise for 20 RM followed by cardiorespiratory endurance exercise for 24-25 minutes (type I), lower extremity muscles endurance exercises for 10 RM followed by cardiorespiratory endurance exercises for 26-27 minutes (type II), and threw a tennis ball with 10 m distance for 10 minutes as control (type III). These program was performed 3 times a week for 4 months. Assesment of the exercise effectiveness was done by measuring maximum load that can be lifted and six-minutes walking test on rectangular track which was converted with the VO2 max prediction formula. Analysis was perfomed with Kruskal Wallis test. RESULTS: two hundred and twelve (212) subjects were included in the study, randomly allocated into three types (I, II, and III) of exercises groups. The type II of endurance exercise model was proved to be more effective in increasing lower extremity muscles endurance level compared to type I and III for ID patients with obesity (p<0.05). Meanwhile, type I of endurance exercise model was proved to be more effective in increasing cardiorespiratory endurance level compared to type II and III for ID patients with obesity (p<0.05). CONCLUSION: lower extremity muscles endurance exercise followed by a cardiorespiratory endurance exercise can be used to increase physical fitness in ID patients with obesity.

AIM: To investigate the effect of cholecalciferol supplementation on hand grip strength, walking speed, and expression of vitamin D receptor (VDR), interleukine-6 (IL-6) and insulin-like growth factor-1 (IGF-1) in monocyte in pre-frail older adults. METHODS: We conducted a randomized double-blinded placebo-controlled clinical trial for 12 weeks, involving 120 pre-frail older adults who were randomized to the cholecalciferol group (cholecalciferol 4000 IU/day) or the placebo group. All subjects were given calcium lactate 500 mg/day. Hand grip strength and walking speed, as primary outcomes, were analyzed using intention-to-treat analysis. The expression of VDR, IGF-1 and IL-6 in monocytes, as secondary outcomes, were analyzed using per-protocol analysis. RESULTS: After a 12-week intervention, there was a significant increase in serum 25(OH)D levels in both groups, with the increase being higher in the cholecalciferol group than in the placebo group (49.05 vs. 24.01 ng/mL; P < 0.001). No statistically significant differences were observed in hand grip strength (P = 0.228) and walking speed (P = 0.734) between the groups. There were no differences in the expression of VDR (P = 0.513), IL-6 (P = 0.509), and IGF-1 (P = 0.503) monocytes between the groups. CONCLUSIONS: Cholecalciferol supplementation for 12 weeks increased serum 25(OH)D levels among pre-frail older adults. However, it did not improve hand grip strength and walking speed, and nor did it change the expression of VDR, IL-6, and IGF-1 in monocytes. Geriatr Gerontol Int 2024; 24: 554-562.

This study developed a formula for calculating the predicted VO2 max value using a prototype model of foot-based cardiorespiratory exercise. Forty sedentary workers (20 men and 20 women) were enrolled via consecutive sampling. They underwent direct measurement of VO2 max using spiroergometry as the gold standard; the predicted VO2 max value was calculated using a prototype model of foot-based cardiorespiratory exercise, which was performed on consecutive days. Multivariate linear regression analysis was used to formulate the equation for the predicted VO2 max value by including potential contributing variables: gender, body height, body weight and heart rate. Bland-Altman test was used for assessing the agreement level for the predicted VO2 max value. The equation for the predicted VO2 max value was formulated as 3.2 + 0.15 optimal exercise heart rate -5.5 sexes (0 for men, 1 for women). The agreement level for the formula was acceptable in all measurement result ranges. The formula developed in this study can be used to measure the predicted VO2 max value with an acceptable agreement level.

AIM: To determine the effect of alfacalcidol on muscle strength and functional mobility in Indonesian older women whose handgrip strength was low. METHODS: A randomized, double-blind controlled trial was carried out among 95 older women whose handgrip strength was ≤22 kg. Participants were randomized into two groups: 47 participants received alfacalcidol 0.5 µg/day and 48 participants received a placebo. Each participant in both groups was given calcium 500 mg/day. Handgrip strength as well as the Timed-Up and Go test were measured before and after 90 days of intervention. Per protocol analysis after intervention between two groups was carried out. RESULTS: There was a significant improvement of handgrip strength in the group that received alfacalcidol compared with the placebo group (15.50 vs 13.75; P = 0.003). The median time for the Timed-Up and Go test in the alfacalcidol group also improved significantly compared with the placebo group (9.01 vs 10.07, P = 0.028). CONCLUSIONS: Alfacalcidol with daily doses of 0.5 µg significantly improved muscle strength and functional mobility in Indonesian older women. Geriatr Gerontol Int 2018; 18: 434-440.
