RESUMEN
BACKGROUND: To examine the effectiveness and safety of a data sharing and comprehensive management platform for institutionalized older patients. METHODS: We applied information technology-supported integrated health service platform to patients who live at long-term care hospitals (LTCHs) and nursing homes (NHs) with cluster randomized controlled study. We enrolled 555 patients aged 65 or older (461 from 7 LTCHs, 94 from 5 NHs). For the intervention group, a tablet-based platform comprising comprehensive geriatric assessment, disease management, potentially inappropriate medication (PIM) management, rehabilitation program, and screening for adverse events and warning alarms were provided for physicians or nurses. The control group was managed with usual care. Co-primary outcomes were (1) control rate of hypertension and diabetes, (2) medication adjustment (PIM prescription rate, proportion of polypharmacy), and (3) combination of potential quality-of-care problems (composite quality indicator) from the interRAI assessment system which assessed after 3-month of intervention. RESULTS: We screened 1119 patients and included 555 patients (control; 289, intervention; 266) for analysis. Patients allocated to the intervention group had better cognitive function and took less medications and PIMs at baseline. The diabetes control rate (OR = 2.61, 95% CI 1.37-4.99, p = 0.0035), discontinuation of PIM (OR = 4.65, 95% CI 2.41-8.97, p < 0.0001), reduction of medication in patients with polypharmacy (OR = 1.98, 95% CI 1.24-3.16, p = 0.0042), and number of PIMs use (êµ = - 0.27, p < 0.0001) improved significantly in the intervention group. There was no significant difference in hypertension control rate (OR = 0.54, 95% CI 0.20-1.43, p = 0.2129), proportion of polypharmacy (OR = 1.40, 95% CI 0.75-2.60, p = 0.2863), and improvement of composite quality indicators (êµ = 0.03, p = 0.2094). For secondary outcomes, cognitive and motor function, quality of life, and unplanned hospitalization were not different significantly between groups. CONCLUSIONS: The information technology-supported integrated health service effectively reduced PIM use and controlled diabetes among older patients in LTCH or NH without functional decline or increase of healthcare utilization.

Marine organisms, such as sea urchins like Heliocidaris crassispina, produce bioactive substances with antimicrobial activity to protect themselves from the high density of microorganisms in their habitats. One such substance, Echinochrome A (Ech A), has been isolated from various sea urchins' shells and spines using strong acidic solutions and organic solvents. Ech A, however, has not been reported from the coelomic fluid of H. crassispina. In this study, we report the antimicrobial activity of H. crassispina coelomic fluid extract against various microbes, evaluating its potential for purifying potent antimicrobial materials. Upon confirming the extract as a promising source of antimicrobial materials, we isolated antimicrobial compounds from the extract. A series of HPLC steps were taken to purify antimicrobial materials from the H. crassispina coelomic fluid extract, resulting in the isolation of two single absorbance peaks showing antimicrobial activity against Staphylococcus aureus. One peak consisted of a single antimicrobial compound with a molecular weight (MW) corresponding to Ech A, while the other peak comprised five MWs inferred to be those of Ech A and its oxidative products. The elution of Ech A in two separate peaks may be attributable to the presence of Ech A's isomer, as reported in several previous studies. The use of the environmentally friendly extraction method in procurement of Ech A from the coelomic fluid would contribute to the implementation of risk-reducing extraction method for researchers studying Ech A from sea urchins.

Animal models have been utilized to understand the pathogenesis of Zellweger spectrum disorders (ZSDs); however, the link between clinical manifestations and molecular pathways has not yet been clearly established. We generated peroxin 5 homozygous mutant zebrafish (pex5-/-) to gain insight into the molecular pathogenesis of peroxisome dysfunction. pex5-/- display hallmarks of ZSD in humans and die within one month after birth. Fasting rapidly depletes lipids and glycogen in pex5-/- livers and expedites their mortality. Mechanistically, deregulated mitochondria and mechanistic target of rapamycin (mTOR) signaling act together to induce metabolic alterations that deplete hepatic nutrients and accumulate damaged mitochondria. Accordingly, chemical interventions blocking either the mitochondrial function or mTOR complex 1 (mTORC1) or a combination of both improve the metabolic imbalance shown in the fasted pex5-/- livers and extend the survival of animals. In addition, the suppression of oxidative stress by N-acetyl L-cysteine (NAC) treatment rescued the apoptotic cell death and early mortality observed in pex5-/-. Furthermore, an autophagy activator effectively ameliorated the early mortality of fasted pex5-/-. These results suggest that fasting may be detrimental to patients with peroxisome dysfunction, and that modulating the mitochondria, mTORC1, autophagy activities, or oxidative stress may provide a therapeutic option to alleviate the symptoms of peroxisomal diseases associated with metabolic dysfunction.

Background and objectives: Musculoskeletal (MSK) pain significantly impacts physical activity and quality of life in older adults, potentially influencing mortality. This study explored the relationship between MSK pain, physical activity, muscle mass, and mortality among older adults. Material and Methods: We studied 1000 participants in the Korean Longitudinal Study on Health and Aging (KLoSHA), a prospective, population-based cohort study of people aged 65 years or older. Survival status was tracked over a 5-year period. Correlations between low back pain (LBP), knee pain, regular exercise, appendicular skeletal muscle mass (ASM), and other variables were analyzed. Logistic regression analyses were used to identify independent risk factors for mortality. Results: Of the total participants, 829 (82.9%) survived over a 5-year period. Survivors tended to be younger, had a higher BMI, and were more active in regular exercise. In contrast, non-survivors exhibited a higher prevalence of both LBP and knee pain, along with increased instances of multiple MSK pains. Lower ASM correlated moderately with LBP and knee pain, whereas higher ASM was associated with regular exercise. There was a moderate correlation between LBP and knee pain, both of which were associated with a lack of regular exercise. Age, sex, ASM, and regular exercise were significant predictors, even though MSK pain itself did not directly predict all-cause mortality. Conclusions: This study demonstrated the independent association between ASM, regular exercise, and mortality. Although MSK pain did not directly correlate with all-cause mortality, the non-survivor group had higher levels of both single and multiple MSK pains. Recognizing the interplay of MSK pain, physical activity, and muscle mass for older adults, the research underscores the need for holistic strategies to enhance health outcomes in older individuals with MSK pain.

INTRODUCTION/AIMS: Effective strategies for rapid recovery after surgery are needed. Therefore, we investigated the effects of exercise prehabilitation (EP) and hindlimb unloading (HU) on muscle loss and contractility. METHODS: Twenty-two Sprague-Dawley rats (12 wk old) were divided into normal control (NCON, n = 5), hindlimb unloading control (HCON, n = 10), and exercise prehabilitation followed by hindlimb unloading (Ex-preH, n = 7) groups. Ex-PreH performed exercise training for 14 days before hindlimb unloading for 14 days. Body composition was evaluated, along with muscle strength and function. The soleus (SOL) and extensor digitorum longus (EDL) muscle contractile properties were analyzed at the whole-muscle level. The titin concentration and myosin heavy chain (MHC) type composition were analyzed. RESULTS: There were no effects of Ex-preH on total mass, lean mass, or muscle weight. Physical function was significantly higher in the Ex-preH group than in the HCON group (39.5° vs. 35.7°). The SOL twitch force (19.6 vs. 7.1 mN/m2 ) and specific force (107.3 vs. 61.2 mN/m2 ) were greater in Ex-preH group than in HCON group. EDL shortening velocity was higher in Ex-preH group than in HCON group (13.2 vs. 5.0 FL/s). The SOL full-length titin level was higher in Ex-preH group than in HCON group. DISCUSSION: Exercise prehabilitation did not prevent muscle mass loss followed by muscle wasting, although it minimized the reduction of physical function. Therefore, exercise prehabilitation should be considered for rapid functional recovery after disuse due to surgery and injuries.

BACKGROUND: Despite many studies on home-based primary care (HBPC)-related benefits and challenges, little is known about the perspectives of potential target groups of the care and their intention or preference for using it. This study aimed to explore the demand for HBPC from the perspective of people with disabilities (PWDs) and caregivers and identify relevant determinants for that demand. METHODS: Data from the population-based survey conducted in the Gyeonggi Regional Health & Medical Center for People with Disabilities in South Korea were analyzed. Logistic regression analysis was performed to identify relevant determinants for the demand on HBPC. RESULTS: Overall, 22% of respondents required HBPC, and 34.7% of persons aged ≥ 65 years demanded it. Older adults with disability, homebound status, and a need for assistance with daily living activities were associated with a demand for HBPC. Though having severe disability, only 19.49% of self-reported respondents demanded for HBPC, while 39.57% of proxy-reported respondents demanded for HBPC. Among self-reported group, only marital status was a predictor associated with a demand for HBPC. In contrast, among proxy-reported groups, PWDs with external physical disabilities, or with unmet medical needs due to availability barriers reported a higher demand for HBPC. CONCLUSIONS: The demand for HBPC does not derive from the medical demands of the users themselves, but rather the care deficit by difficulty in getting out of the house or in outpatient care. Beyond an alternative to office-based care, HBPC needs to be considered to solve the care deficit and as well as to deal with PWDs' medical problems.

Introduction: Limited range of motion (ROM) of the shoulder occurs commonly after breast cancer surgery, resulting in reduced quality of life and difficulty with activities of daily living. Physical exercise is effective in postoperative breast cancer patients, but no study has assessed the effects of augmented reality (AR)-based telerehabilitation. Therefore, this study aimed to investigate the effect of hospital-home linked rehabilitation therapy using an AR-based digital health care system (UINCARE Home+) in postoperative patients with breast cancer. Methods: This study was a prospective, multicenter, assessor-blinded, randomized controlled trial. Patients who underwent breast cancer surgery were assigned to either the UINCARE Home+ (intervention) group or the brochure-based home rehabilitation (control) group for an 8-week intervention. The study outcomes were the change in ROM of the affected shoulder, pain in the affected shoulder (Numerical Rating Scale [NRS]), functional outcomes (Disabilities of the Arm, Shoulder, and Hand questionnaire [QuickDASH] score), and quality of life (Functional Assessment of Cancer Therapy-Breast [FACT-B] and EuroQoL 5-Dimension 5-Level [EQ-5D-5L] scores), all of which were measured at enrollment and at 4, 8, and 12 weeks thereafter. Results: A total of 100 participants were enrolled in the study (n = 50 in each groups). In both groups, active and passive ROM, NRS, and the QuickDASH, FACT-B, and EQ-5D-5L scores showed significant improvements from baseline to 12 weeks (p < 0.001), but no group differences were detected. Discussion: A home-based exercise program with an AR system improved shoulder dysfunction in breast cancer patients and could be used in conjunction with a traditional hospital-based rehabilitation program.

INTRODUCTION: Digital healthcare systems based on augmented reality (AR) show promise for postoperative rehabilitation. We compared the effectiveness of AR-based rehabilitation and conventional rehabilitation after total knee arthroplasty (TKA). MATERIALS AND METHODS: We randomly allocated 56 participants to digital healthcare rehabilitation group (DR group) and conventional rehabilitation group (CR group). Participants in the CR group performed brochure-based home exercises for 12 weeks, whereas those in the DR group performed AR-based home exercises that showed each motion on a monitor and provided real-time feedback. The primary outcome was change in 4-m gait speed. The secondary outcomes were the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, health-related quality of life [assessed by the EuroQoL 5-Dimension 5-Level (EQ5D5L) questionnaire], pain [measured using a numeric rating scale (NRS)], Berg Balance Scale (BBS), range of motion (ROM), and muscle strength. Outcomes were measured at baseline (T0) and 3 (T1), 12 (T2), and 24 (T3) weeks after randomization. RESULTS: There was no significant difference in baseline characteristics of participants between two groups, except age and body mass index. No group difference was observed in 4-m gait speed (0.37 ± 0.19 and 0.42 ± 0.28 for the DR and CR groups, respectively; p = 0.438). The generalized estimating equation model revealed no significant group by time interaction regarding for 4-m gait speed, WOMAC, EQ5D5L, NRS, BBS, ROM, and muscle strength score. All outcomes were significantly improved in both groups (p < 0.001). CONCLUSION: The use of a digital healthcare system based on AR improved the functional outcomes, pain, and quality of life of patients after TKA. AR-based rehabilitation may be useful treatment as an alternative to conventional rehabilitation. TRIAL REGISTRATION: ClinicalTrials.gov (identifier: NCT04513353).

Background and Objectives: When considering surgery for patients with breast cancer-related lymphedema (BCRL), it is crucial to determine which surgery will be most effective for the patient and establish the indications for each surgery. Our study retrospectively compared the results of preoperative noncontrast MR lymphangiography (NMRL) performed on the lymphedematous limb of patients before surgery, with the aim of analyzing whether preoperative NMRL can be used as a criterion for determining the type of surgery. Materials and Methods: From January 2020 to June 2022, a total of 138 patients with lymphedema underwent surgery at Seoul National University Bundang Hospital. All patients underwent preoperative NMRL imaging and were classified into stages 1-3 based on the MRI severity index using the authors' previous reference. Three types of surgery, LVA, LVA + liposuction, and LVA + VLNT, were conducted on all patients. The effectiveness of the surgery was evaluated one year postoperatively using the interlimb volume difference before and after surgery, the fluid volume of the edematous limb measured by bioimpedance spectroscopy, and the subjective satisfaction of the patients through the Lymph Q questionnaire. Results: In this study, out of a total of 138 patients, 26 (19%) were MRI stage 1, 62 (45%) were stage 2, and 50 (36%) were stage 3. Of the 83 patients who underwent LVA surgery, the greatest decrease in interlimb volume difference was observed in stage 2 patients, and subjective satisfaction was also the most effective in stage 2. In the case of LVA + liposuction patients, a significant volume decrease and a high satisfaction were observed in stage 3 patients. In the case of LVA + VLNT patients, there was no difference in volume decrease according to the stage, but a greater decrease in body fluid volume was observed as the MRI severity index score increased through BIA. Conclusions: In conclusion, this study demonstrates that NMRL imaging is a useful modality for determining the most effective surgical method and predicting the surgical outcome in patients with lymphedema. This highlights the importance of using NMRL in the treatment planning of lymphedema patients.

INTRODUCTION: We aimed to investigate the correlation between spinal sarcopenia, spinal sagittal balance (SSB), and spinal function in older women living in rural areas versus those of the older urban women in our previous study. METHODS: Twenty-five older rural-dwelling women aged more than 70 years were compared with 24 older urban-dwelling women from our previous study. Demographic variables, conventional and spinal sarcopenic indices, variable functional outcome parameters, occupational state, and exercise participation rate were evaluated. We also measured the isometric back extensor strength, radiological parameters for SSB on whole-spine radiography, and volumetric parameters of the lumbar extensor muscle on computed tomography. RESULTS: There were no significant intergroup differences in demographic variables or the prevalence of sarcopenia. Older women in rural areas had greater handgrip strength than those in urban areas (22.7±3.7 kg v 20.0±3.4 kg, p=0.010). However, their mean lumbar lordosis angle was lower (31.7±15.3° v 42.3±11.2°, p=0.012). Isometric back extensor strength was lower in rural women than in urban women. The vocational activity participation rate of rural women was significantly higher (84% v 12.5%, p<0.001), whereas their exercise participation rate was significantly lower (60% v 92%, p<0.001). CONCLUSION: Older women in rural areas had greater handgrip strength and vocational participation rates but lower back extensor strength and exercise participation rates. Therefore, more attention is needed for healthcare services to support their spinal health and exercise habits.

Rotavirus infection has been reported to be associated with neonatal seizures with a diffuse and symmetrical diffusion restriction of periventricular white matter, namely, neonatal rotavirus-associated leukoencephalopathy. The extensive white matter injury seen in this cohort raises concerns about the long-term neurodevelopmental outcomes. In the present study, we prospectively assessed the neurodevelopmental outcomes of 13 patients with neonatal rotavirus-associated leukoencephalopathy at a median age of 26 months (range, 23-68 months). Neurodevelopmental outcomes were evaluated using a neurological examination, developmental evaluations, and magnetic resonance imaging (MRI) of the brain. Overall, 6 of the 13 patients (46%) had abnormal neurodevelopmental outcomes: 1 patient had mental retardation, visual-motor integration (VMI) dysfunction, cerebral palsy, and epilepsy; 1 patient had cerebral palsy and VMI dysfunction; remaining 4 patients had VMI dysfunction. Follow-up MRI in 12 of 13 patients showed an increased signal intensity on periventricular white matter in all patients. These findings suggested that neonatal rotavirus-associated leukoencephalopathy could not be assumed to be benign in long-term neurodevelopment, particularly in VMI function. Early intervention and long-term follow-up are necessary for these patients. Our findings raise caution for rotavirus infection in this vulnerable population for infants.

Skeletal muscle strength, mass, and function should be carefully monitored for signs of decline with advanced adult age. An understanding of the pathophysiology and severity of sarcopenia can be improved with the exploration of changes in muscle fiber properties. Furthermore, although functional decline with increase age is a well-known phenomenon, the mechanisms underlying this decline, and the features that characterize it, are complex and variable. The age-related decline of muscle function is a result of not only a decrease of muscle mass but also a decline in the intrinsic properties of muscle fibers that are independent of size. We believe it is important to understand changes in muscle quality (force adjusted for size), and not to focus solely on muscle mass, because muscle quality is closely related to measurements of function and could potentially predict clinical outcomes such as morbidity, disability, and mortality. Neurological and metabolic mechanisms contribute to muscle quality, but the intrinsic properties of muscle cells are central to the maintenance of force-generating capacity. Muscle quality can be evaluated with the assessment of morphological, physiological, and mechanical properties in single permeabilized or skinned fibers. This approach excludes the influence of the nervous system, tendons, and the extracellular matrix. In this review, we summarized the changes in active and passive mechanical properties at the single muscle cell level in older skeletal muscles. We argue that intrinsic mechanical changes in human single muscle fibers are useful biomarkers and indicators of muscle quality.

BACKGROUND: This study investigated the demand for and awareness of a primary healthcare pilot project for people with disabilities; it also sought to identify relevant determinants for demand and awareness using Andersen's behavioral model of health service use. METHODS: This study is a secondary analysis of data from the population-based survey conducted in Gyeonggi Regional Health & Medical Center for People with Disabilities. The data was designed with quota random sampling based on the population with disabilities in each district (city [si] and county [gun]) across the Gyeonggi province (do) to evaluate the health and healthcare accessibility of the disabled people living in the Gyeonggi province. The data was collected through the mobile-based survey of 1,140 people with disabilities living in Gyeonggi-do between March 2021 and June 2021. RESULTS: Awareness of the service (12.1%) was remarkably low, while the demand (80.5%) was high. The gap between respondents who needed the service but were unaware of it differed according to age, education, activities of daily living, health information sources, chronic disease, depression, subjective health status, and unmet healthcare needs. Chronic disease (odds ratio [OR], 1.86; P = 0.001) and an unmet need for medical care (OR, 2.30; P = 0.002) had significant influences on demand for the service. Furthermore, living alone (OR, 0.42; P = 0.023), medical aid program beneficiary status (OR, 2.10; P = 0.020), access to health information from health service centers (OR, 4.00; P = 0.002), chronic disease (OR, 1.68; P = 0.043), severity of disability (OR, 1.78; P = 0.025), and subjective health status (OR, 4.51; P < 0.001) significantly affected awareness of the program. CONCLUSION: Chronic disease and an unmet need for medical care were key determinants of service demand, while the severity of disability was not. Thus, there is a need to review the initiative that defines service beneficiaries as people with severe disabilities. Policy makers should consider advertising programs to improve service awareness among people with disabilities.

BACKGROUND: This study aimed to investigate the effects of comprehensive rehabilitation management on functional recovery and examine the correlation between clinical parameters and improvements in functional outcomes in severe-to-critical inpatients with coronavirus disease 2019 (COVID-19) in a tertiary hospital. METHODS: Post-acute COVID-19 patients who had a World Health Organization (WHO) ordinal scale of 5-7, underwent intensive care, and received comprehensive rehabilitation management, including exercise programs, nutritional support, dysphagia evaluation, and psychological care were included. The appendicular skeletal muscle mass index (SMI), Medical Research Council sum score, handgrip strength, number of repetitions in the 1-minute sit-to-stand test, gait speed, Berg Balance Scale (BBS), and Functional Ambulation Classification (FAC) were evaluated at hospital stay, discharge, and 1-month follow-up. The correlation between the rehabilitation dose and improvement in each outcome measure was analyzed. RESULTS: Overall, 37 patients were enrolled, of whom 59.5% and 32.4% had a score of 6 and 7 on the WHO ordinal scale, respectively. Lengths of stay in the intensive care unit and hospital were 33.6 ± 23.9 and 63.8 ± 36.5 days. Outcome measures revealed significant improvements at discharge and 1-month follow-up. The SMI was significantly increased at the 1-month follow-up (6.13 [5.24-7.76]) compared with that during the hospital stay (5.80 [5.39-7.05]). We identified dose-response associations between the rehabilitation dose and FAC (ρ = 0.46) and BBS (ρ = 0.50) scores. Patients with older age, longer hospitalization, longer stay at the intensive care unit, longer duration of mechanical ventilation, tracheostomy, a more depressive mood, and poorer nutritional status revealed poorer improvement in gait speed at the 1-month follow-up. CONCLUSION: Comprehensive rehabilitation management effectively improved muscle mass, muscle strength, and physical performance in severe-to-critical COVID-19 patients. Dose-response relationship of rehabilitation and functional improvement emphasizes the importance of intensive post-acute inpatient rehabilitation in COVID-19 survivors.

BACKGROUND: The incidence and number of fragility hip fractures are gradually increasing, resulting in a wide consumption of medical resources. Various factors affecting functional recovery in patients with fragility hip fractures are known, and comorbid diseases are one of them. The purpose of this study is to determine the effect of comorbidities on functional outcomes in patients surgically treated for fragility hip fractures, thereby contributing to the efficient distribution of medical resources. METHODS: This was a retrospective cohort study performed in the three tertiary rehabilitation facilities. A total of 211 patients (50 men and 161 women; average age 81.6 ± 6.7 years) who had undergone surgery for fragility hip fractures were followed up from immediately after transfer to the Department of Rehabilitation Medicine to 6 months postoperatively. Comorbidities referred to a summary of the following conditions: hypertension, diabetes mellitus, chronic liver disease, dementia, cerebrovascular accident, and osteoporosis. Functional outcomes included Koval's grade, Functional Ambulatory Category (FAC), Functional Independence Measure (FIM)-locomotion, Modified Rivermead Mobility Index, Berg Balance Scale (BBS), 4-Meter Walking speed Test (4MWT), the Korean version of the Mini-Mental State Examination(K-MMSE), Geriatric Depression Scale (GDS), EuroQol Five-Dimension (EQ-5D) questionnaire, the Korean version of the Modified Barthel Index (K-MBI), the Korean version of the Instrumental Activities of Daily Living (K-IADL), and Korean version of Fatigue, Resistance, Ambulation, Illnesses, and Loss of weight scale (K-FRAIL). For all tests, each patient was assessed immediately after transfer and 6 months post-surgery. RESULTS: Multivariate linear regression analyses adjusted for age, sex, the initial variable of the functional outcomes, and comorbidities revealed that dementia had a significant negative impact on Koval's grade and K-FRAIL 6 months postoperatively. Diabetes mellitus had a significant negative impact on the FAC, GDS, EQ-5D, K-IADL, and K-FRAIL 6 months postoperatively. Patients with osteoporosis showed a significant negative outcome of FIM-locomotion 6 months postoperatively. A cerebrovascular accident revealed a significant negative impact on the BBS 6 months postoperatively. In addition, hypertension led to significantly less favorable outcomes of the K-FRAIL 6 months postoperatively. CONCLUSIONS: This study confirmed that comorbidities, particularly dementia and diabetes mellitus, significantly influence functional outcomes 6 months after fragility hip fracture surgeries.

AIM: To examine the effects of a rural community-based program integrating health education and self-directed home-based resistance training on the mobility function of older women with knee osteoarthritis (OA). METHODS: Participants were assigned to the control (CON) or intervention (INT) group. Participants completed a mobility function assessment and questionnaire evaluation. The CON group received only the health education program and the INT group also participated in resistance training for 5 months. Primary outcomes were mobility function measured using a timed chair stand (TCS), timed up & go (TUG), gait speed (GS), and knee extensor strength (KES). We evaluated body composition and questionnaire results (WOMAC score, SARC-F scale, and SOF index) as secondary outcomes. RESULTS: There were significant differences in the interactions of group-by-time effects for TCS (p < 0.001), TUG (p = 0.006), GS (p = 0.020), and knee strength (p = 0.010). In the CON group, TCS (p = 0.003) and TUG (p = 0.005) increased compared with baseline, while in the INT group, TCS decreased significantly (p < 0.001) and TUG tended to decrease after the intervention. The INT group showed improvement in GS (p < 0.001) and KES (p = 0.003) after the intervention. By contrast, the CON group showed decreasing GS (p = 0.021) and KES (p = 0.011) compared with baseline. The SARC-F scale differed significantly in the interaction of group-by-time effects (p = 0.030), while the body composition, SOF index, and WOMAC score did not differ. CONCLUSION: These results suggest that an integrated intervention program combining self-directed home-based resistance training with health education effectively improves the mobility function of older adults with knee OA dwelling in rural areas.

BACKGROUND: As the primary treatment for adhesive capsulitis, intensive and accurate home exercise is as important as physical therapy in hospitals. Augmented reality (AR)-based telerehabilitation has been implemented recently in various musculoskeletal conditions to increase patient compliance and enable patients to exercise with the correct posture. The objective of this study is to present a protocol for investigating the additive effect of interactive AR-based telerehabilitation in comparison with the usual care for patients with adhesive capsulitis. METHODS: This study presents the protocol of a prospective, multi-center, single-blinded, two-armed randomized controlled trial (RCT). One hundred patients with stage I or II adhesive capsulitis will be recruited at the physical medicine and rehabilitation clinic. Patients will be randomly divided into two groups with 1:1 allocation. The intervention group will receive 3 months of hospital-based physical therapy in conjunction with home-based telerehabilitation. The control group will receive 3 months of hospital-based physical therapy in conjunction with a home-based exercise described in a brochure provided by the hospital. The primary outcome will be the change in passive range of motion (ROM) of the affected shoulder joint from baseline to 12 weeks after baseline assessment. The secondary outcomes will be active ROM, pain measured with the numeric rating scale, shoulder pain and disability index, 36-Item Short Form Survey, EuroQoL-5D-5L, and Canadian Occupational Performance Measure. DISCUSSION: This will be the first RCT study protocol to investigate the effect of telerehabilitation in patients with adhesive capsulitis. The result of this RCT will determine whether AR-based telerehabilitation is more effective than a brochure-based home exercise program and will provide evidence of the usefulness of "telerehabilitation" using hardware (IoT) and software (monitoring platform) technologies to develop "digital therapeutics" for the future. TRIAL REGISTRATION: This trial was retrospectively registered at the Clinicaltrials.gov website on 20 March 2020, with the identifier NCT04316130 .

OBJECTIVE: Accelerated loss of muscle mass is common in patients with chronic kidney disease (CKD). Various factors associated with CKD, such as nutritional deficiencies, metabolic acidosis, and chronic inflammation, contribute to muscle wasting. This study aimed to investigate the relationship between CKD and handgrip strength (HGS) in the Korean population. DESIGN AND METHODS: This is a population-based, cross-sectional study of a nationally representative sample of 18,765 patients aged ≥19 years from the Korea National Health and Nutrition Examination Survey in 2014-2017. We measured HGS using a digital hand dynamometer and determined the cutoff for low HGS by deriving -2 standard deviation values of sex-matched healthy young adults (19-39 years old). We defined CKD as eGFR <60 mL/min/1.73 m2 or the presence of CKD based on a self-reported questionnaire. RESULTS: The prevalence of CKD was 4.0% in the total population. The cutoff values for the low HGS were 29.5 kg for men and 16.8 kg for women. The prevalence of low HGS was 6.2% in patients without CKD, and 25.2% in patients with CKD. There was a significant correlation between HGS and eGFR in both men and women. In multivariate logistic regression adjusted by age group, diabetes, hypertension, and obesity, CKD showed an independent relationship with low HGS in both men (odds ratio [OR] 1.910, 95% confidence interval [CI] 1.468-2.485) and women (OR 1.570, 95% CI 1.202-2.052). CONCLUSIONS: The prevalence of low HGS was higher in patients with CKD. We suggest that the sarcopenia should be evaluated in patients with CKD.

RESUMEN
BACKGROUND: The results of total hip arthroplasty (THA) with use of Delta ceramic articulation were successful at medium term follow-up. The use of this newest ceramic has markedly reduced the incidence of ceramic head fractures, but not the incidence of ceramic liner fractures. We tested a hypothesis that the ceramic fractures are prevented by use of a metal shell with 18° inner taper angle and a stem design with a reduced neck geometry. METHODS: We conducted a prospective multicenter study of cementless THA with use of 32/36-mm Delta ceramic bearing, Exceed ABT metal shell and Taperloc stem. We evaluated ceramic fracture, noise, clinical results, radiological changes and survival rate at a minimum of 5-year follow-up. RESULTS: From April 2010 to February 2012, 246 patients (274 THAs) were enrolled. Among them, 224 patients (130 men and 94 women, 250 hips) were followed-up for 5-8 years (mean 6.0 years). Ceramic malseating or fracture did not occur in any patient. Eight patients (8 hips, 3.2%) reported noise. Mean Harris hip score was 84 points at the latest follow-up. All acetabular and femoral components had bone-ingrown stability. Two hips were revised due to recurrent dislocation and periprosthetic fracture. The survival rate was 99.6% at 8 years postoperatively. CONCLUSION: Ceramic fractures can be prevented by a use of (1) 32/36-mm Delta ceramic bearing, (2) metal shell with 18° taper angle, and (2) stem with a reduced neck geometry. However, noise remains a concern of the Delta ceramic bearing. LEVEL OF EVIDENCE: Therapeutic level II.
