Abstract
Key Points In the lower-parathyroid hormone (PTH) group, associations between serum alkaline phosphatase (ALP) and all-cause mortality were positive and linear. In the higher-PTH group, lower serum ALP tended to have higher risk than those with intermediate serum ALP. Serum ALP was independently and linearly associated with new hip fracture regardless of intact PTH level. Background Monitoring of serum alkaline phosphatase (ALP) is recommended in the management of CKD–mineral bone disorder because of associations with poor outcomes among patients on dialysis. However, such associations may have changed with several advances in the management of CKD–mineral bone disorder over the past decade. Methods Baseline data of 241,670 patients on dialysis (mean age, 69±12 years; male, 65.9%; median dialysis duration, 68 months) were extracted from a nationwide dialysis registry in Japan at the end of 2019. Outcomes, including all-cause and cardiovascular (CV) mortality and hip fracture, were evaluated using the registry at the end of 2020 and 2021. All-cause mortality was assessed using Cox regression analysis, whereas CV mortality and new hip fracture were assessed using competing-risks regression analysis. Multiple imputations for missing values were performed. Results Within the 2-year study period, a total of 40,449 patients (16.7%) died, including 13,562 CV deaths (5.6%). Of the 168,836 patients with no history of hip fracture at the end of 2019, 4136 (2.4%) suffered hip fracture within 2 years. Higher serum ALP was independently associated with higher all-cause and CV mortality and new hip fracture, but the association with CV mortality was marginal (hazard ratio, 1.21; 95% confidence interval [CI], 1.18 to 1.24; subhazard ratio, 1.07; 95% CI, 1.03 to 1.12 and subhazard ratio, 1.28, 95% CI, 1.19 to 1.38, respectively). There is a linear association between serum ALP and all-cause mortality among the lower parathyroid hormone (PTH) group, whereas lower serum ALP tended to have higher all-cause mortality than intermediate serum ALP among patients in the higher PTH group. Conclusions Higher serum ALP was independently and linearly associated with higher all-cause and CV mortality and new hip fracture in Japanese patients on dialysis. Higher serum ALP and higher intact PTH were synergistic in increasing all-cause and CV mortality but were not associated with new hip fracture.

Abstract
BACKGROUND Peritoneal dialysis (PD) and haemodialysis (HD) are two possible modalities for people with kidney failure commencing dialysis. Only a few randomised controlled trials (RCTs) have evaluated PD versus HD. The benefits and harms of the two modalities remain uncertain. This review includes both RCTs and non-randomised studies of interventions (NRSIs). OBJECTIVES To evaluate the benefits and harms of PD, compared to HD, in people with kidney failure initiating dialysis. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies from 2000 to June 2024 using search terms relevant to this review. Studies in the Register were identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal, and ClinicalTrials.gov. MEDLINE and EMBASE were searched for NRSIs from 2000 until 28 March 2023. SELECTION CRITERIA RCTs and NRSIs evaluating PD compared to HD in people initiating dialysis were eligible. DATA COLLECTION AND ANALYSIS Two investigators independently assessed if the studies were eligible and then extracted data. Risk of bias was assessed using standard Cochrane methods, and relevant outcomes were extracted for each report. The primary outcome was residual kidney function (RKF). Secondary outcomes included all-cause, cardiovascular and infection-related death, infection, cardiovascular disease, hospitalisation, technique survival, life participation and fatigue. MAIN RESULTS A total of 153 reports of 84 studies (2 RCTs, 82 NRSIs) were included. Studies varied widely in design (small single-centre studies to international registry analyses) and in the included populations (broad inclusion criteria versus restricted to more specific participants). Additionally, treatment delivery (e.g. automated versus continuous ambulatory PD, HD with catheter versus arteriovenous fistula or graft, in-centre versus home HD) and duration of follow-up varied widely. The two included RCTs were deemed to be at high risk of bias in terms of blinding participants and personnel and blinding outcome assessment for outcomes pertaining to quality of life. However, most other criteria were assessed as low risk of bias for both studies. Although the risk of bias (Newcastle-Ottawa Scale) was generally low for most NRSIs, studies were at risk of selection bias and residual confounding due to the constraints of the observational study design. In children, there may be little or no difference between HD and PD on all-cause death (6 studies, 5752 participants: RR 0.81, 95% CI 0.62 to 1.07; I2 = 28%; low certainty) and cardiovascular death (3 studies, 7073 participants: RR 1.23, 95% CI 0.58 to 2.59; I2 = 29%; low certainty), and was unclear for infection-related death (4 studies, 7451 participants: RR 0.98, 95% CI 0.39 to 2.46; I2 = 56%; very low certainty). In adults, compared with HD, PD had an uncertain effect on RKF (mL/min/1.73 m2) at six months (2 studies, 146 participants: MD 0.90, 95% CI 0.23 to 3.60; I2 = 82%; very low certainty), 12 months (3 studies, 606 participants: MD 1.21, 95% CI -0.01 to 2.43; I2 = 81%; very low certainty) and 24 months (3 studies, 334 participants: MD 0.71, 95% CI -0.02 to 1.48; I2 = 72%; very low certainty). PD had uncertain effects on residual urine volume at 12 months (3 studies, 253 participants: MD 344.10 mL/day, 95% CI 168.70 to 519.49; I2 = 69%; very low certainty). PD may reduce the risk of RKF loss (3 studies, 2834 participants: RR 0.55, 95% CI 0.44 to 0.68; I2 = 17%; low certainty). Compared with HD, PD had uncertain effects on all-cause death (42 studies, 700,093 participants: RR 0.87, 95% CI 0.77 to 0.98; I2 = 99%; very low certainty). In an analysis restricted to RCTs, PD may reduce the risk of all-cause death (2 studies, 1120 participants: RR 0.53, 95% CI 0.32 to 0.86; I2 = 0%; moderate certainty). PD had uncertain effects on both cardiovascular (21 studies, 68,492 participants: RR 0.96, 95% CI 0.78 to 1.19; I2 = 92%) and infection-related death (17 studies, 116,333 participants: RR 0.90, 95% CI 0.57 to 1.42; I2 = 98%) (both very low certainty). Compared with HD, PD had uncertain effects on the number of patients experiencing bacteraemia/bloodstream infection (2 studies, 2582 participants: RR 0.34, 95% CI 0.10 to 1.18; I2 = 68%) and the number of patients experiencing infection episodes (3 studies, 277 participants: RR 1.23, 95% CI 0.93 to 1.62; I2 = 20%) (both very low certainty). PD may reduce the number of bacteraemia/bloodstream infection episodes (2 studies, 2637 participants: RR 0.44, 95% CI 0.27 to 0.71; I2 = 24%; low certainty). Compared with HD; It is uncertain whether PD reduces the risk of acute myocardial infarction (4 studies, 110,850 participants: RR 0.90, 95% CI 0.74 to 1.10; I2 = 55%), coronary artery disease (3 studies, 5826 participants: RR 0.95, 95% CI 0.46 to 1.97; I2 = 62%); ischaemic heart disease (2 studies, 58,374 participants: RR 0.86, 95% CI 0.57 to 1.28; I2 = 95%), congestive heart failure (3 studies, 49,511 participants: RR 1.10, 95% CI 0.54 to 2.21; I2 = 89%) and stroke (4 studies, 102,542 participants: RR 0.94, 95% CI 0.90 to 0.99; I2 = 0%) because of low to very low certainty evidence. Compared with HD, PD had uncertain effects on the number of patients experiencing hospitalisation (4 studies, 3282 participants: RR 0.90, 95% CI 0.62 to 1.30; I2 = 97%) and all-cause hospitalisation events (4 studies, 42,582 participants: RR 1.02, 95% CI 0.81 to 1.29; I2 = 91%) (very low certainty). None of the included studies reported specifically on life participation or fatigue. However, two studies evaluated employment. Compared with HD, PD had uncertain effects on employment at one year (2 studies, 593 participants: RR 0.83, 95% CI 0.20 to 3.43; I2 = 97%; very low certainty). AUTHORS' CONCLUSIONS The comparative effectiveness of PD and HD on the preservation of RKF, all-cause and cause-specific death risk, the incidence of bacteraemia, other vascular complications (e.g. stroke, cardiovascular events) and patient-reported outcomes (e.g. life participation and fatigue) are uncertain, based on data obtained mostly from NRSIs, as only two RCTs were included.

THE AMERICAN JOURNAL OF PATHOLOGY 2024; 194:759-771.

Abstract
In patients with chronic kidney disease (CKD), skeletal muscle mass and function are known to occasionally decline. However, the muscle regeneration and differentiation process in uremia has not been extensively studied. In mice with CKD induced by adenine-containing diet, the tibialis anterior muscle injured using a barium chloride injection method recovered poorly as compared to control mice. In the cultured murine skeletal myocytes, stimulation with indoxyl sulfate (IS), a representative uremic toxin, morphologically jeopardized the differentiation, which was counteracted by L-ascorbic acid (L-AsA) treatment. Transcriptome analysis of cultured myocytes identified a set of genes whose expression was down-regulated by IS stimulation but up-regulated by L-AsA treatment. Gene silencing of myomixer, one of the genes in the set, impaired myocyte fusion during differentiation. By contrast, lentiviral overexpression of myomixer compensated for a hypomorphic phenotype caused by IS treatment. The split-luciferase technique demonstrated that IS stimulation negatively affected early myofusion activity that was rescued by L-AsA treatment. Lastly, in mice with CKD compared with control mice, myomixer expression in the muscle tissue in addition to the muscle weight after the injury was reduced, both of which were restored with L-AsA treatment. Collectively, data showed that the uremic milieu impairs the expression of myomixer and impedes the myofusion process. Considering frequent musculoskeletal injuries in uremic patients, defective myocyte fusion followed by delayed muscle damage recovery could underlie their muscle loss and weakness.

Abstract
Fractures represent a major cause of disability in the elderly, and patients with fractures exhibit a higher mortality rate than those without. Fractures are also an important health problem among patients with end-stage kidney disease (ESKD) requiring hemodialysis, peritoneal dialysis, or kidney transplantation. To the best of our knowledge, no study in the literature has yet quantitatively summarized the mortality rates, and a summary of evidence on post-hip and spine fracture mortality in patients with ESKD is lacking. The purpose of this study is to quantitatively evaluate the mortality rate, one-year mortality rate, and five-year mortality rate after hip and spine fractures in patients with ESKD receiving kidney replacement therapy. The MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, and ClinicalTrials.gov databases were comprehensively searched for reports on mortality rate and time-period mortality in patients with ESKD after hip or spine fractures up to June 2022. Prospective and retrospective cohort studies, as well as case series involving four or more patients, were included. Pooled mortality rate, one-year rate, and five-year mortality rate with 95% confidence intervals (CIs) were examined using a random-effects model. The risk of bias was assessed using the Joanna Briggs Institute (JBI) Prevalence Critical Appraisal Tool. Additionally, heterogeneity between studies was evaluated. A total of 26 studies were included in this meta-analysis. The one-year and five-year mortality rates after hip and spine fractures were 215.35-774.0 per 1,000 person-year and 148-194.1 per 1,000 person-year, respectively. After hip fractures, the one-year mortality rate was 27% (95% CI: 18-38%, I2 = 98%), whereas the five-year mortality rate was 56% (95% CI: 41-71%, I2 = 99%). After spine fractures, the one-year mortality rate was 10% (95% CI: 4-17%, I2 = 70%), whereas the five-year mortality rate was 48.3%. The post-fracture mortality rate was high in patients with ESKD, particularly within one year after the occurrence of fractures. Additionally, the five-year mortality rate after hip femoral or spine fractures was high at approximately 50%.

Abstract
Introduction Proximal femur fragility fractures (PFFFs) are a growing worldwide concern. Recognizing the risk factors for subsequent fracture is essential for secondary prevention. This study aimed to analyze the risk factors for refracture and mortality rates in patients who suffered a PFFF. Methods Patients aged 65 years or older with PFFF who underwent surgical treatment during the year of 2017 in the same institution were retrospectively analyzed and at least four years after the index fracture were evaluated. Results From a total of 389 patients, 299 patients were included, with a median age of 83 years, and 81% female. Thirty-two (10.7%) suffered a refracture, with a mean time to refracture of 19.8 ± 14.80 months, being the female sex a risk factor for refracture (OR-4.69; CI [1.05-20.95]). The 1-year mortality rate was 15.4%. Seventy-three (24.4%) patients had previous fragility fractures. After the index fracture, 79% remained untreated for osteoporosis. No statistical association was found between antiosteoporotic treatment and refracture. Patients with refracture had higher prefracture functional level compared with patients without refracture (OR-1.33; CI [1.08-1.63]) and were discharged more often to rehabilitation units (31% versus 16%, P =.028). After 4 years of follow-up, patients with refracture had lower functional level compared with patients without. Chronic kidney disease was a risk factor (P = .029) for early refracture (<24 months). Conclusion Female sex and higher prefracture functional level may increase the risk of refracture. Chronic kidney disease was associated with a shorter refracture time. Despite having a PFFF or other fragility fractures, the majority of patients remained untreated for osteoporosis.

Abstract
Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD) comprises alterations in calcium, phosphorus, parathyroid hormone (PTH), Vitamin D, and fibroblast growth factor-23 (FGF-23) metabolism, abnormalities in bone turnover, mineralization, volume, linear growth or strength, and vascular calcification leading to an increase in bone fractures and vascular disease, which ultimately result in high morbidity and mortality. The bone component of CKD-MBD, referred to as renal osteodystrophy, starts early during the course of CKD as a result of the effects of progressive reduction in kidney function which modify the tight interaction between mineral, hormonal, and other biochemical mediators of cell function that ultimately lead to bone disease. In addition, other factors, such as osteoporosis not apparently dependent on the typical pathophysiologic abnormalities resulting from altered kidney function, may accompany the different varieties of renal osteodystrophy leading to an increment in the risk of bone fracture. After kidney transplantation, these bone alterations and others directly associated or not with changes in kidney function may persist, progress or transform into a different entity due to new pathogenetic mechanisms. With time, these alterations may improve or worsen depending to a large extent on the restoration of kidney function and correction of the metabolic abnormalities developed during the course of CKD. In this paper, we review the bone lesions that occur during both CKD progression and after kidney transplant and analyze the factors involved in their pathogenesis as a means to raise awareness of their complexity and interrelationship.

Abstract
Osteoporosis is a common bone health disorder in hemodialysis patients that is linked with a higher morbidity and mortality rate. While previous studies have explored the associated factors of osteoporosis, there is a lack of studies investigating the impacts of health literacy (HL) and digital healthy diet literacy (DDL) on osteoporosis. Therefore, we aimed to investigate the associations of HL, DDL, and other factors with osteoporosis among hemodialysis patients. From July 2020 to March 2021, a cross-sectional study was conducted on 675 hemodialysis patients in eight hospitals in Vietnam. The data were collected by using the osteoporosis self-assessment tool for Asians (OSTA) and the 12-item short form of the health literacy questionnaire (HLS-SF12) on digital healthy diet literacy (DDL) and hemodialysis dietary knowledge (HDK). In addition, we also collected information about the socio-demographics, the clinical parameters, the biochemical parameters, and physical activity. Unadjusted and adjusted multinomial logistic regression models were utilized in order to investigate the associations. The proportion of patients at low, medium, and high levels of osteoporosis risk was 39.6%, 40.6%, and 19.8%, respectively. In the adjusted models, women had a higher likelihood of osteoporosis risk than men (odds ratio, OR, 3.46; 95% confidence interval, 95% CI, 1.86, 6.44; p < 0.001; and OR, 6.86; 95% CI, 2.96, 15.88; p < 0.001). The patients with rheumatoid arthritis (OR, 4.37; 95% CI, 1.67, 11.52; p = 0.003) and stomach ulcers (OR, 1.95; 95% CI, 1.01, 3.77; p = 0.048) were more likely to have a higher likelihood of osteoporosis risk than those without. The patients who had a higher waist circumference (WC), HL, and DDL were less likely to have a medium level of osteoporosis risk (OR, 0.95; 95% CI, 0.92, 0.98; p = 0.004; OR, 0.92; 95% CI, 0.88, 0.96; p < 0.001; OR, 0.96; 95% CI, 0.93, 0.99; p = 0.017, respectively) and a high level of osteoporosis risk (OR, 0.93; 95% CI, 0.89, 0.97; p = 0.001; OR, 0.89; 95% CI, 0.84, 0.94; p < 0.001; OR, 0.95; 95% CI, 0.91, 0.99; p = 0.008, respectively) compared with a low level of osteoporosis risk and to those with a lower WC, HL, and DDL. In addition, higher levels of hemoglobin (Hb) (OR, 0.79; 95% CI, 0.66, 0.95; p = 0.014), hematocrit (Hct) (OR, 0.95; 95% CI, 0.92, 0.99; p = 0.041), albumin (OR, 0.91; 95% CI, 0.83, 0.99; p = 0.030), and education (OR, 0.37; 95% CI, 0.16, 0.88; p = 0.025) were associated with a lower likelihood of a high level of osteoporosis risk. In conclusion, osteoporosis risk is highly prevalent in hemodialysis patients. Improved HL, DDL, education, WC, albumin, Hb, and Hct levels should be considered in preventing hemodialysis patients from developing osteoporosis.

Kim Y, Lee E, Lee MJ, Park B, Park I. Characteristics of fracture in patients who firstly starts kidney replacement therapy in Korea: a retrospective population-based study. Sci Rep 2022; 12:3107. [PMID: 35210536 PMCID: PMC8873500 DOI: 10.1038/s41598-022-07178-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Accepted: 01/31/2022] [Indexed: 11/17/2022] Open
Abstract
The incidence of fractures in patients with end-stage kidney disease (ESKD) is high which is associated with high morbidity and mortality. Since fractures are preventable diseases to some extent, epidemiologic studies are needed a lot. The aim of this study is to explore the epidemiology of fractures by modality of kidney replacement therapy (KRT). We performed a retrospective analysis of 52,777 patients dependent on KRT from 2008 to 2017 using the National Health Insurance System of Republic Korea. Fractures were occurred in 8995 (17.04%) of 52,777 patients with ESKD. Hemodialysis and kidney transplant patients had the highest (57.4 per 1000 person-year) and the lowest (25.2 per 1000 person-year) incidence rate, respectively. The two most common fracture sites were the lower limb and upper limb, regardless of KRT modality. The first fractures were about 2.55 ± 2.07 years after KRT initiation, the earliest in Hemodialysis patients. Diabetes mellitus, cerebrovascular disease, chronic lung and liver disease were risk factors of fractures. The use of steroids, anti-osteoporosis medications, and some classes of psychotropics and opioids was associated with an elevated risk. The results of this study inform the understanding of fractures in KRT patients.

Abstract
INTRODUCTION Romosozumab reportedly increases bone mineral density (BMD) potently but might adversely affect cardiovascular disease (CVD). We evaluated the efficacy of romosozumab in osteoporotic HD patients with a high risk of fracture. MATERIALS AND METHODS This was a single-center 1-year study in Japanese HD patients. Among 96 HD romosozumab-treated HD patients with high risk of fracture, 76 HD patients completed 1 year of subcutaneous administration of romosozumab (210 mg/4 weeks) for 1 year. Romosozumab-untreated HD patients (n = 55) were also included. Changes in BMD and serum markers, together with fracture occurrence, and CVD events, were monitored. RESULTS During romosozumab treatment of 76 HD patients, BMD time-dependently increased significantly by 15.3% ± 12.9% at the lumbar spine (L1-4), and 7.2% ± 8.3% at the femoral neck at 1 year. Serum BAP and total P1NP increased significantly and serum TRACP-5b decreased at 4 weeks. Fragility fractures occurred in three (3.8%) patients. Hypocalcemia occurred at 4-48 weeks despite the increased dosing of active vitamin-D derivatives, but without any symptom. New CVD events occurred in 5.2% of romosozumab-treated HD patients and10.9% in romosozumab-untreated HD patients. CONCLUSIONS BMD was increased significantly during romosozumab treatment at the lumbar spine, and the femoral neck, respectively, at 1 year in HD patients. Hypocalcemia occurred but without any intolerable event. There was no apparent increase in CVD events during 1 year of study, suggesting romosozumab as a promising agent for HD patients with severe osteoporosis.

Abstract
Purpose In older adults, the one-year mortality rate after experiencing a hip fracture ranges between 8% and 36%. The purpose of this study was to look at the efficacy of rehabilitation-based multidisciplinary care for older individuals who had hip fractures. Patients and Methods The study included 185 people (aged 65 and over) with a history of hip fracture surgery between February 2014 and March 2017. A survey was conducted one month and six months following the operation to assess the recovery of 93 individuals who were part of a rehabilitation-based multidisciplinary care program and 92 patients who were getting standard therapy with surgery and unsupervised physical therapy. Results Physical activity, gait, balance evaluation, and depression scale ratings all had statistical significance (P < 0.05) after participants received rehabilitation-based care services from multidisciplinary medical professionals. Furthermore, the refracture and one-year mortality rates in this rehabilitation-based multidisciplinary care model were lower than in the groups getting standard therapy. Conclusion The research indicates the efficacy of a multidisciplinary rehabilitation strategy provided by a collaborative medical team to older individuals with hip fractures.

Abstract
BACKGROUND Although malnutrition and bone fracture are both major complications in patients undergoing hemodialysis, their association has not been clarified. The aim of our study was to clarify the association between the geriatric nutritional risk index (GNRI), an indicator of nutritional status, and the incidence of bone fractures in patients undergoing hemodialysis. METHODS We included 1342 registered patients undergoing hemodialysis and performed a post hoc analysis. We divided patients into the high GNRI group (≥92), considered to have a low risk of malnutrition, and the low GNRI group (<92), considered to have a high risk of malnutrition. Fracture-free survival in the low and high GNRI groups was evaluated by the Kaplan-Meier method. Cox proportional hazards models were used to identify the risk factors for fractures requiring hospitalization. All results were stratified by sex. RESULTS New bone fractures developed in 108 (8.0%) patients in 5 years of follow-up. Bone fractures occurred more frequently in the low GNRI group compared with the high GNRI group (HR: 3.51, 95% CI: 1.91-6.42, p < 0.01 in males; HR: 2.47, 95% CI: 1.52-4.03, p < 0.01 in females). A low GNRI was significantly associated with an increased incidence of bone fractures, even after adjustment for covariates. However, the serum levels of calcium, phosphate, parathyroid hormone, and alkaline phosphatase were not associated with the incidence of bone fractures. CONCLUSIONS A low GNRI is an independent risk factor for bone fractures in patients undergoing hemodialysis. Early intervention for the low GNRI group may be important in preventing the occurrence of fractures.

Abstract
Background The risk of death and complications after major trauma in patients with chronic kidney disease (CKD) is higher than in the general population, but whether this association holds true among Canadian trauma patients is unknown. Objectives To characterize patients with CKD/receiving dialysis within a regional major trauma cohort and compare their outcomes with patients without CKD. Methods All major traumas requiring hospitalization between 2006 and 2017 were identified from a provincial trauma registry in Nova Scotia, Canada. Trauma patients with stage ≥3 CKD (estimated glomerular filtration rate <60 mL/min/1.73 m2) or receiving dialysis were identified by cross-referencing two regional databases for nephrology clinics and dialysis treatments. The primary outcome was in-hospital mortality; secondary outcomes included hospital/intensive care unit (ICU) length of stay (LOS) and ventilator-days. Cox regression was used to adjust for the effects of patient characteristics on in-hospital mortality. Results In total, 6237 trauma patients were identified, of whom 4997 lived within the regional nephrology catchment area. CKD/dialysis trauma patients (n=101; 28 on dialysis) were older than patients without CKD (n=4896), with higher rates of hypertension, diabetes, and cardiovascular disease, and had increased risk of in-hospital mortality (31% vs 11%, p<0.001). No differences were observed in injury severity, ICU LOS, or ventilator-days. After adjustment for age, sex, and injury severity, the HR for in-hospital mortality was 1.90 (95% CI 1.33 to 2.70) for CKD/dialysis compared with patients without CKD. Conclusion Independent of injury severity, patients without CKD/dialysis have significantly increased risk of in-hospital mortality after major trauma.

Abstract
INTRODUCTION Bone loss in end stage renal disease (ESRD) patients associates with fractures, vascular calcification, cardiovascular disease (CVD) and increased mortality. We investigated factors associated with changes of bone mineral density (ΔBMD) during the initial year on dialysis therapy and associations of ΔBMD with subsequent mortality in ESRD patients initiating dialysis. MATERIALS AND METHODS In 242 ESRD patients (median age 55 years, 61% men) starting dialysis with peritoneal dialysis (PD; n = 138) or hemodialysis (HD; n = 104), whole-body dual-energy X-ray absorptiometry (DXA), body composition, nutritional status and circulating biomarkers were assessed at baseline and 1 year after dialysis start. We used multivariate linear regression analysis to determine factors associated with ΔBMD, and fine and gray competing risk analysis to determine associations of ΔBMD with subsequent mortality risk. RESULTS BMD decreased significantly in HD patients (significant reductions of BMDtotal and BMDleg, trunk, rib, pelvis and spine) but not in PD patients. HD compared to PD therapy associated with negative changes in BMDtotal (β=- 0.15), BMDhead (β=- 0.14), BMDleg (β=- 0.18) and BMDtrunk (β=- 0.16). Better preservation of BMD associated with significantly lower all-cause mortality for ΔBMDtotal (sub-hazard ratio, sHR, 0.91), ΔBMDhead (sHR 0.91) and ΔBMDleg (sHR 0.92), while only ΔBMDhead (sHR 0.92) had a beneficial effect on CVD-mortality. CONCLUSIONS PD had beneficial effect compared with HD on BMD changes during first year of dialysis therapy. Better preservation of BMD, especially in bone sites rich in cortical bone, associated with lower subsequent mortality. BMD in cortical bone may have stronger association with clinical outcome than BMD in trabecular bone.

Abstract
OBJECTIVE To investigate the relationship between poor oral health and the incidence of fall-related fractures in older Japanese individuals. DESIGN A 9-year prospective cohort study. SETTING AND PARTICIPANTS Participants comprised 937 community-dwelling older Japanese adults aged 70 years or older. They all lived in the Tsurugaya district, a suburban area of Sendai city, and underwent comprehensive geriatric assessment, including an oral examination, in a public facility. MEASUREMENTS The exposure variables were related to oral health status (posterior occlusal support, number of remaining teeth, and occlusal force). The outcome measure was the incidence of fall-related fractures, which was determined by National Health Insurance data. Analyzed covariates included age, sex, medical history, smoking, alcohol drinking, educational level, depressive symptoms, cognitive impairment, physical function, body mass index, and history of falls. Statistical relationships were examined by calculating hazard ratios (HRs) at 95% confidence intervals (CIs) using the Cox proportional hazard model. RESULTS In the multivariate analysis, the HRs of fall-related fractures were significantly higher in those with unilateral posterior occlusal support (HR, 2.72; 95% CI, 1.13-6.55) and no posterior occlusal support (HR, 2.58; 95% CI, 1.29-5.15) than in those with bilateral posterior occlusal support. The HRs (95% CIs) of fall-related fractures in individuals with 10-19 and 1-9 teeth and edentulous individuals were 1.77 (0.81-3.89), 2.67 (1.24-5.75), and 2.31 (1.01-5.28), respectively, compared to those with ≥20 teeth. CONCLUSIONS AND IMPLICATIONS Poor oral health status is a risk factor for the incidence of fall-related fractures in community-dwelling older Japanese individuals. The findings suggest that attention should be focused on oral health status to further understand the risk of fall-related fractures among community-dwelling older adults.

Abstract
BACKGROUND Previous studies evaluating fractures in chronic kidney disease (CKD) have mostly focused on hip or major fractures in aged populations with moderate to advanced CKD. We aimed at evaluating the association between early CKD and fracture incidence at all sites across age and sex in middle-aged individuals. METHODS We analyzed CARTaGENE, a prospective population-based survey of 40- to 69-year-old individuals from Quebec (Canada). Estimated glomerular filtration rate (eGFR) at baseline was evaluated categorically or continuously using restricted cubic splines. Fractures at any site (except toes, hand and craniofacial) for up to 7 years of follow-up were identified through administrative databases using a validated algorithm. Adjusted Cox models were used to evaluate the association of CKD with fracture. Interaction terms for age and sex were also added. RESULTS A total of 19 391 individuals (756 CKD Stage 3; 9114 Stage 2; 9521 non-CKD) were included and 829 fractures occurred during a median follow-up of 70 months. Compared with the median eGFR of 90 mL/min/1.73 m2, eGFRs of ≤60 mL/min/1.73 m2 were associated with increased fracture incidence in unadjusted and adjusted models [adjusted hazard ratio (HR) = 1.25 (95% confidence interval 1.05-1.49) for 60 mL/min/1.73 m2; 1.65 (1.14-2.37) for 45 mL/min/1.73 m2]. The eGFR was linearly associated with fracture incidence <75 mL/min/1.73 m2 [HR = 1.18 (1.04-1.34) per 10 mL/min/1.73 m2 decrease] but not above [HR = 0.98 (0.91-1.06) per 10 mL/min/1.73 m2 decrease). The effect of decreased eGFR on fracture incidence was more pronounced in younger individuals [HR = 2.45 (1.28-4.67) at 45 years; 1.11 (0.73-1.67) at 65 years] and in men. CONCLUSIONS Even early CKD increases fracture incidence, especially in younger individuals and in men.

Abstract
Patients with chronic kidney disease have a higher risk of fractures than the general population due to the added factor of uraemia. Although the mechanisms behind uraemia-associated fractures are not fully understood, it is widely accepted that the decrease in bone mineral content and alteration in bone architecture both increase bone fragility. As chronic kidney disease progresses, the risk of fracture increases, especially once the patient requires dialysis. Among the many causes of the increased risk are advanced age, amenorrhoea, steroid exposure, decreased vitamin D, increased PTH, malnutrition and chronic inflammation. Serum phosphorus, whether high or very low, seems to correlate with the risk of fracture. Moreover, increased serum phosphate is known to directly and indirectly affect bone metabolism through the development of adaptive hormonal mechanisms aimed at preventing hyperphosphataemia, such as the increase in PTH and FGF23 and the reduction in calcitriol. These adaptive mechanisms are less intense if the intestinal absorption of phosphorus is reduced with the use of phosphorus captors, which seem to have a positive impact in reducing the risk of fractures. We describe here the possible mechanisms associating serum phosphorus levels, the adaptive mechanisms typical in kidney disease and the use of drugs to control hyperphosphataemia with the risk of fractures. We found no studies in the literature providing evidence on the influence of different treatments on the risk of fractures in patients with chronic kidney disease. We suggest that control of phosphorus should be an objective to consider.

Abstract
OBJECTIVES Subjective memory complaints (SMCs) in the elderly are associated with poor recovery in performing activities of daily living. This study was designed to examine SMCs and their association with recovery and health outcomes of older persons within 1 year following hospital discharge after hip-fracture surgery. METHODS Data were collected between 2012 and 2015 from 194 hip-fractured elders in northern Taiwan. SMCs were assessed by the Prospective and Retrospective Memory Questionnaire. Recovery outcomes included self-care ability (activities of daily living [ADLs] and instrumental activities of daily living [IADLs]), physical function (range of motion and maximal muscle strength), cognitive function, delirium, depressive symptoms, and health-related quality of life (HRQoL). Outcomes were assessed before discharge and 1, 3, 6, and 12 months afterwards. Associations of SMCs with participants' recovery outcomes were examined by the generalized estimating equation approach. RESULTS Participants with SMCs had significantly poorer recovery outcomes than those without SMCs. Additionally, the interaction term for time-by-SMC was significant on ADLs, IADLs, maximal strength of quadriceps muscles, maximal strength of hip abductor muscles, ankle dorsiflexion, and HRQoL, suggesting that negative associations with SMCs increased over time. Participants with SMCs were at significantly higher risk for cognitive impairment and delirium than those without SMCs. CONCLUSIONS Participants with SMCs not only had worse recovery than those without SMCs, but their rate of recovery was also slower during the first year following hip-fracture surgery. Therefore, SMCs need to be assessed to identify patients at high risk for worse recovery outcomes following hip fracture.

Abstract
UNLABELLED Having rheumatoid arthritis (RA) or end-stage renal disease (ESRD) can lead to fractures. RA independently increases the risk of hip or other femur fracture in dialysis patients. Use of corticosteroids is a potentially modifiable risk factor for fractures among persons with RA and ESRD on dialysis. PURPOSE Rheumatoid arthritis (RA) and end-stage renal disease (ESRD) both independently increase fracture risk; however, how RA and ESRD interplay to affect fracture risk is unknown. We aim to determine the association of RA with fracture in ESRD and identify risk factors for fracture in patients with RA and ESRD. METHODS A retrospective cohort study was conducted using the United States Renal Data System (USRDS) to identify ESRD adults with and without a history of RA who initiated dialysis in 2005-2008. International Classification of Diseases, 9th Revision (ICD-9) codes were used to identify fractures following start of dialysis. Risk for incident fracture was compared between those with and without RA. Potential risk factors for fracture among persons with RA and ESRD were analyzed. RESULTS There were 754 persons with ESRD and RA, of whom 126 (17%) had any incident fracture. In multivariable adjusted final models, among ESRD patients, RA was an independent risk factor for hip/femur fracture (RR 1.28, 95% CI 1.01-1.64). Among persons with RA and ESRD, in final models, only corticosteroid use was a significant risk factor for both any incident (RR 2.00, 95% CI 1.40-2.87) and hip/femur (RR 1.97, 95% CI 1.24-3.11) fracture. Those with higher body mass index had a lower relative risk of hip/femur fracture (RR 0.95, 95% CI 0.91-0.99). CONCLUSION Among ESRD patients, those with RA have a 28% increased risk for hip or other femur fracture. Use of corticosteroids is a potentially modifiable risk factor for fractures among persons with RA and ESRD.

Abstract
BACKGROUND The purpose of this study was to analyze the all-cause mortality rate over time after elderly hip fracture in end-stage renal disease (ESRD) patients with dialysis, using a Korean nationwide claims database. METHODS This retrospective nationwide study identified subjects from the Korean National Health Insurance Service-Senior cohort (NHIS-Senior). The NHIS-Senior (total of 588,147 participants) was constructed by 10% random sampling and was designed to represent the elderly living in Korea. Subjects were patients aged 65-99 years who underwent surgical treatment for femoral neck fractures or intertrochanteric fractures. A generalized estimating equation model with Poisson distribution and logarithmic link function was used to estimate adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) to measure associations between renal dialysis and cumulative mortality in various time frames. RESULTS The total number of patients included in this study was 16,818. These patients were divided into two groups: 116 (0.69%) in the dialysis group and 16,702 (99.31%) in the no-dialysis group. The mean length of hospital stay was 43.87 ± 48.45 days in the dialysis group and 36.29 ± 37.49 days in the no-dialysis group (P = 0.095). The effect of renal dialysis on all-cause mortality was 2.29-fold (aRR; 95% CI, 1.29-4.06; P = 0.005) within 30 days and 1.72-fold (aRR; 95% CI, 1.34-2.21; P < 0.001) within 1-year after hip fracture compared to the no-dialysis group. And, the effect of renal dialysis of in-hospital mortality was 2.72-fold (aRR; 95% CI, 1.71-4.33; P < 0.001) compared to the no-dialysis group. CONCLUSION Elderly patients who underwent dialysis have very high mortality rates after hip fracture. Therefore, it is considered that postoperative care through multidisciplinary management and understanding of pathophysiology for the ESRD patients is necessary.

Abstract
Osteoporosis characterized by low bone mineral density (BMD) as assessed by dual-energy X-ray absorptiometry (DXA) is common among end-stage renal disease (ESRD) patients and associates with high fracture incidence and high all-cause mortality. This is because chronic kidney disease-mineral bone disorders (CKD-MBDs) promote not only bone disease (osteoporosis and renal dystrophy) but also vascular calcification and cardiovascular disease. The disturbed bone metabolism in ESRD leads to 'loss of cortical bone' with increased cortical porosity and thinning of cortical bone rather than to loss of trabecular bone. Low BMD, especially at cortical-rich bone sites, is closely linked to CKD-MBD, vascular calcification and poor cardiovascular outcomes. These effects appear to be largely mediated by shared mechanistic pathways via the 'bone-vascular axis' through which impaired bone status associates with changes in the vascular wall. Thus, bone is more than just the scaffolding that holds the body together and protects organs from external forces but is-in addition to its physical supportive function-also an active endocrine organ that interacts with the vasculature by paracrine and endocrine factors through pathways including Wnt signalling, osteoprotegerin (OPG)/receptor activator of nuclear factor-κB (RANK)/RANK ligand system and the Galectin-3/receptor of advanced glycation end products axis. The insight that osteogenesis and vascular calcification share many similarities-and the knowledge that vascular calcification is a cell-mediated active rather than a passive mineralization process-suggest that low BMD and vascular calcification ('vascular ossification') to a large extent represent two sides of the same coin. Here, we briefly review changes of BMD in ESRD as observed using different DXA methods (central and whole-body DXA) at different bone sites for BMD measurements, and summarize recent knowledge regarding the relationships between 'low BMD' and 'fracture incidence, vascular calcification and increased mortality' in ESRD patients, as well as potential 'molecular mechanisms' underlying these associations.

Abstract
The association between serious falls and dialysis modality [hemodialysis (HD) and peritoneal dialysis (PD)] is unclear. A nationwide population-based retrospective cohort study with 127,823 end-stage renal disease patients aged over 18 years was conducted with the unmatched cohort of 101,304 HD and 7,584 PD patients retrieved from Taiwan's National Health Insurance Research Database during 2000-2013. A total of 7,584 HD and 7,584 PD patients matched at 1:1 ratio by propensity score were enrolled to the study. Serious falls were defined by the diagnostic codes, E code, and image studies. Cox regression model and competing-risk model were used for statistical analysis. HD patients were older and had more comorbidities at baseline than PD patients. After matching and adjustment, HD patients had a higher risk of serious falls than PD patients [sHR 1.27 (95% CI 1.06-1.52)]. Females, elders, a history of falls before dialysis, comorbidity with stroke or visual problems, using diuretics, α-blockers, and mydriatics were associated with higher risks of serious falls among dialysis patients. The risk of serious falls was higher in HD patients than PD patients. Health professionals should create age-friendly environments, reduce unnecessary medications, and raise patients' awareness of falls in daily life.

Abstract
BACKGROUND Major fractures (MF) are common in dialysis patients. We investigated incidence, predictors and clinical outcomes associated with first MF occurring after initiation of dialysis (MFfirst). METHODS In Swedish Renal Registry of 9714 incident (2005-2016) dialysis patients (age 68 years, 67% men), we identified all MFfirst in hip, spine, humerus and forearm. Using flexible parametric hazard models and Fine-Gray analysis, we estimated incidence, mortality rates and predictors of MFfirst, and, in time-dependent analysis, risk of all-cause and cardiovascular disease (CVD) mortality following MFfirst. RESULTS During median follow-up of 2.2 years, the crude incidence rate of MFfirst (n = 835) was 23.7/1000 patient-years and that of hip fractures (n = 470) 13.3/1000 patient-years. The multivariate-adjusted fracture incidence rates increased gradually after dialysis initiation and were 47% higher among women. Female sex, higher age, comorbidity, and previous history of MF (MFprevious) were associated with increased risk for MFfirst, whereas peritoneal dialysis as compared to hemodialysis was associated with decreased risk. The adjusted fracture incidence rate of MFfirst during the first 90 days following dialysis initiation was higher in patients with MFprevious than in those without MFprevious. MFfirst independently predicted increased all-cause (sub-distribution hazard ratio, SHR, 1.67(95%CI 1.47-1.91)) and CVD (SHR 1.49 (95%CI 1.22-1.84)) mortality. Adjusted mortality rate following hip fractures was higher than for other types of MF. Spline curves showed that mortality following MFfirst was highest during the first 6 months of follow-up. CONCLUSIONS MF are common and associated with increased mortality in incident dialysis patients.

Abstract
BACKGROUND The aim of this study is to compare perioperative outcomes, readmission, and mortality after hemiarthroplasty for hip fractures in diabetic patients with different renal function statuses. METHODS In this retrospective population-based cohort study, diabetic patients who received primary hemiarthroplasty for hip fracture between January 1997 and December 2013 were identified from the Taiwan National Health Insurance Research Database. Primary outcomes were perioperative outcomes including infection and revision. Secondary outcomes were all-cause readmission and mortality. RESULTS A total of 29,535 diabetic patients were included: 8270 patients had chronic kidney disease (CKD group), 1311 patients underwent permanent dialysis (dialysis group), and 19,954 patients did not have CKD (non-CKD group). During a mean follow-up of 4.5 years, these 3 groups had comparable risks of any infection, including superficial and deep infection. Dialysis patients had a significantly higher risk of revision than did CKD and non-CKD patients (subdistribution hazard ratio 1.65, 95% confidence interval 1.16-2.36; subdistribution hazard ratio 1.57, 95% confidence interval 1.10-2.24, respectively). Compared with the non-CKD group, the dialysis group had significantly higher risks of readmission and mortality at all time points, namely 3 months after surgery, 1 year after surgery, and the final follow-up. The CKD group also had higher risks of readmission and mortality than did the non-CKD group at all time points. CONCLUSION CKD is associated with poor outcomes following hemiarthroplasty for fragility hip fracture. CKD patients may have higher risks of surgical complications including revision than non-CKD patients, and they have significantly elevated risks of readmission and mortality.

Abstract
OBJECTIVE To determine the cumulative 30-day and 1-year mortality as well as personal independence after hip fracture in patients on hemodialysis. DESIGN Prospective, observational cohort study with matched controls. SETTING One teaching hospital, one metropolitan trauma center, one peripheral hospital. PATIENTS AND INTERVENTION Study group: a consecutive cohort of 64 patients with end-stage renal disease receiving chronic hemodialysis who had undergone surgery for a trochanteric or femoral neck fracture from June 2008 to November 2016. CONTROL GROUP subjects without end-stage renal disease who underwent surgery for similar hip fractures. MAIN OUTCOME MEASURE One-year mortality, activities of daily living, and ambulatory activity. RESULTS The 30-day and 1-year mortality rate in patients with a hip fracture undergoing hemodialysis was 25.0% and 57.8%, respectively. Hemodialysis was independently associated with increased 30-day (Hazard ratio 2.933; 95% confidence interval 1.270-6.770; P = 0.018) and 1-year (hazard ratio 2.535; 95% confidence interval, 1.494-4.299; P < 0.001) mortality compared with the matched controls. At the 1-year follow-up, loss of personal independence in comparison with the prefracture status was detected. CONCLUSIONS Hemodialysis was associated with increased mortality after hip fracture. A worse prefracture functional status predicted the loss of functional independence at follow-up. LEVEL OF EVIDENCE Prognostic Level III.

A multi-imaging modality study of bone density, bone structure and the muscle - bone unit in end-stage renal disease. Bone 2019; 127:271-279. [PMID: 31158505 DOI: 10.1016/j.bone.2019.05.022] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2016] [Revised: 05/16/2019] [Accepted: 05/16/2019] [Indexed: 01/10/2023]
Abstract
End stage renal disease (ESRD) is associated with sarcopenia and skeletal fragility. The objectives of this cross-sectional study were to (1) characterize body composition, bone mineral density (BMD) and bone structure in hemodialysis patients compared with controls, (2) assess whether DXA areal BMD (aBMD) correlates with peripheral quantitative CT (pQCT) measures of volumetric BMD (vBMD), cortical dimensions and MRI measures of trabecular microarchitecture, and (3) determine the magnitude of bone deficits in ESRD after adjustment for muscle mass. Thirty ESRD participants, ages 25 to 64 years, were compared with 403 controls for DXA and pQCT outcomes and 104 controls for MRI outcomes; results were expressed as race- and sex- specific Z-scores relative to age. DXA appendicular lean mass index (ALMI kg/m2) and total hip, femoral neck, ultradistal and 1/3rd radius aBMD were significantly lower in ESRD, vs. controls (all p < 0.01). pQCT trabecular vBMD (p < 0.01), cortical vBMD (p < 0.001) and cortical thickness (due to a greater endosteal circumference, p < 0.02) and MRI measures of trabecular number, trabecular thickness, and whole bone stiffness were lower (all p < 0.01) in ESRD, vs. controls. ALMI was positively associated with total hip, femoral neck, ultradistal radius and 1/3rd radius aBMD and with tibia cortical thickness (R = 0.46 to 0.64). Adjustment for ALMI significantly attenuated bone deficits at these sites: e.g. mean femoral neck aBMD was 0.79 SD lower in ESRD, compared with controls and this was attenuated to 0.33 with adjustment for ALMI. In multivariate models within the dialysis participants, pQCT trabecular vBMD and cortical area Z-scores were significant and independently (all p < 0.02) associated with DXA femoral neck, total hip, and ultradistal radius aBMD Z-scores. Cortical vBMD (p = 0.01) and cortical area (p < 0.001) Z-scores were significantly and independently associated with 1/3rd radius areal aBMD Z-scores (R2 = 0.62). These data demonstrate that DXA aBMD captures deficits in trabecular and cortical vBMD and cortical area. The strong associations with ALMI, as an index of skeletal muscle, highlight the importance of considering the role of sarcopenia in skeletal fragility in patients with ESRD.

Abstract
Background Chronic kidney disease (CKD)-mineral and bone disorder (MBD) and fracture risk are both closely related to declining renal function. Controlling hyperphosphatemia with phosphate binders is a basic principle of CKD-MBD treatment. The aim of this study was to identify differences in fracture risk between pre-dialysis CKD patients and end-stage renal disease (ESRD) on dialysis, and to evaluate the effects of phosphate binders on fracture risk in ESRD patients. Methods Data from a total of 89,533 CKD patients comprising CKD diagnosis, dialysis, fracture history, and phosphate binder prescription history from 2012 to 2016 were retrieved from the Health Insurance Review and Assessment Service Database. Multivariate Cox regression analyses were performed to identify whether dialysis or phosphate binders were associated with an increased fracture risk. Results Overall, the rate of fractures in pre-dialysis CKD patients was 74 per 1,000 patient-years, while that in dialysis patients was 84 per 1,000 patient-years. The risk of fracture in ESRD patients was higher than pre-dialysis CKD patients (hazard ratio, 1.16; 95% confidence interval, 1.12–1.21; P < 0.001) after adjusting for confounding variables. In addition, the fracture risk in patients who were not taking phosphate binders was 20.0% higher compared to ESRD patients taking phosphate binders. Conclusion Fractures were more prevalent in ESRD patients on dialysis than pre-dialysis CKD patients. Use of phosphate binders was associated with a lower fracture risk in ESRD patients.

Abstract
Mineral and bone disorders including osteoporosis are common in dialysis patients and contribute to increased morbimortality. However, whether denosumab and alendronate are effective and safe treatments in hemodialysis patients is not known. Thus, we conducted a prospective, three-center study of 48 hemodialysis patients who were diagnosed as having osteoporosis and had not received anti-osteoporotic agents previously. Participants were randomized to either denosumab or intravenous alendronate, and all subjects received elemental calcium and calcitriol during the initial 2 weeks. The primary endpoint was the percent change in lumbar spine bone mineral density (LSBMD) at 12 months of treatment. The secondary endpoints included the following: change in BMD at other sites; change of serum bone turnover markers (BTM), coronary artery calcium score (CACS), ankle-brachial pressure index (ABI), brachial-ankle pulse wave velocity (baPWV), flow mediated dilation (FMD), and intima-media thickness at the carotid artery (CA-IMT); change from day 0 to day 14 in serum levels of Ca and P; time course of serum calcium (Ca), phosphorus (P), and intact parathyroid hormone (i-PTH); new fractures; and adverse events. Initial supplementation with elemental calcium and calcitriol markedly ameliorated the decrease of serum corrected calcium (cCa) levels induced by denosumab during the first 2 weeks, whereas serum cCa levels in the alendronate group were increased. Denosumab and alendronate markedly decreased serum levels of BTM and increased LSBMD at 12 months compared with baseline. However, no significant differences were found in the changes in LSBMD between the two groups. The serum cCa, P, and i-PTH levels in the two groups were maintained within the appropriate range. In contrast to the anti-osteoporotic effects, no significant differences after 12 months of treatment were found in the CACS, CA-IMT, ABI, baPWV, and FMD compared with pretreatment in both groups. Denosumab and alendronate treatment improved LSBMD, reduced BTM, and appeared to be safe in hemodialysis patients with osteoporosis. © 2019 American Society for Bone and Mineral Research.

Abstract
BACKGROUND Bone and mineral metabolism disorders are common among end-stage renal disease (ESRD) patients, which could lead to hip fracture. It is unclear whether the hip fracture risk is different among patients on hemodialysis (HD) versus peritoneal dialysis (PD). This meta-analysis was conducted to evaluate the hip fracture risk in ESRD patients on HD, when compared to PD. METHODS A literature review was conducted in EMBASE, MEDLINE, and Cochrane databases through January 31, 2018 to identify studies that appraised the rate or risk of hip fracture among patients on HD, when compared to PD. Effect estimates from the individual studies were derived and consolidated utilizing random-effect, generic inverse variance approach of DerSimonian and Laird. RESULTS Five cohort studies with 1 276 677 ESRD patients were enrolled. HD status was associated with a significantly higher risk of hip fracture with the pooled odds ratio (OR) of 1.61 (95% confidence interval [CI] 1.50-1.73, I2 = 10.0%), compared with PD. When the analysis was limited to studies with confounder-adjusted analysis, the pooled OR of hip fracture among HD patients was 1.57 (95% CI 1.43-1.72, I2 = 13.6%). Funnel plots and Egger's regression test demonstrated no significant publication bias in our meta-analysis. CONCLUSIONS Among ESRD patients, HD status is associated with a 61% higher risk of hip fracture compared to PD.

Abstract
There is an increased tendency for hip fractures in patients with chronic kidney disease (CKD). Although surgery is the mainstay of treatment for hip fractures, there is scant information on outcomes after hip fracture surgery in diabetic patients at different stages of CKD. In this population-based cohort study, we compared the surgical outcome, readmission, and mortality rates after osteosynthesis of hip fractures in diabetic patients with different stages of renal function. Diabetic patients who received primary osteosynthesis for hip fracture between January 1997 and December 2013 were enrolled. The primary outcomes were surgical outcomes, including infection and revision surgery. The secondary outcomes were all-cause readmission and mortality. This study included 44,065 patients; 11,954 had CKD (diabetic CKD group), 1662 patients were receiving dialysis (diabetic dialysis group), and 30,449 patients had no CKD (diabetic non-CKD group). We found that the diabetic dialysis group had a significantly higher risk of infection and revision surgery compared with diabetic non-CKD patients (HR = 1.52, 95% CI, 1.24 to 1.87; HR = 1.62, 95% CI, 1.33 to 1.97, respectively, both P < 0.001) and diabetic CKD patients (HR = 1.62, 95% CI, 1.32 to 1.99; HR = 1.48, 95% CI, 1.22 to 1.80, respectively, both P < 0.001). Diabetic CKD patients had a comparable risk of surgical complications including infection and revision as diabetic non-CKD patients. For readmission and mortality, the diabetic dialysis group had the highest risk among the three groups at all time-points (3 months after surgery, 1 year, and the last follow-up, all P < 0.001). Compared with the diabetic non-CKD group, the diabetic CKD group had an elevated risk of readmission and mortality at all time-points (all P < 0.001). In conclusion, CKD was associated with worse outcomes after hip fracture fixation surgery. Although at significantly higher risk of readmission and mortality, CKD patients still had a comparable risk of infection and revision to non-CKD patients. © 2019 American Society for Bone and Mineral Research.

Abstract
Background Renal osteodystrophy has caused increased risk of fragility fracture in end-stage renal disease (ESRD) patients. However, risk factors and outcome of ESRD patients with fragility fracture remain uncharacterized. We aimed to assess these parameters in ESRD patients. Summary This retrospective case-control study analyzed 354 ESRD patients (initial fragility fracture [FF] group, n = 59; control group, n = 295). Pre-dialysis blood hemoglobin, serum albumin, lipid, calcium, phosphorus, alkaline phosphatase (ALP), and intact parathyroid hormone (iPTH) were collected. All procedures performed involving human participants were in accordance with the ethical standards of the institutional committee of The First Affiliated Hospital of Chongqing Medical University (IRB approval number 216-82), and informed consent was obtained from all participants. There were higher prevalence rates of primary hypertension and diabetes, higher serum ALP, corrected calcium, and lower serum total cholesterol, low-density lipoprotein, lipoprotein-α, and iPTH in the FF group. Fractures were more likely to occur in the higher level of corrected calcium as well as in the lower iPTH group. High corrected calcium (p = 0.010, OR = 11.308, 95% CI: 1.770-72.242) and serum ALP (p = 0.000, OR = 1.007, 95% CI: 1.004-1.011) were independent risk factors of fragility fracture. The incidence of all-cause mortality and cardiovascular (CV) events in ESRD patients with fragility fracture was higher than in those without fracture. Key Messages Patients with hypertension, diabetes, excessive suppression of PTH, and poor nutritional status are more prone to fractures. Serum corrected calcium and ALP were independent risk factors of fragility fracture. Patients with initial fragility fracture had more CV events and higher mortality.

Abstract
Chronic kidney disease is associated with an increased risk of fracture and cardiovascular mortality. The risk of fracture in hemodialysis (HD), peritoneal dialysis (PD) and kidney transplant (KT) patients is higher when compared with the general population. However, there exists a knowledge gap concerning which group has the highest risk of fracture. We aimed to compare the risk of fracture in HD, PD, and KT populations. We conducted a systematic review of observational studies evaluating the risk of fracture in HD, PD, or KT patients. Eligible studies were searched using MEDLINE, Embase, Web of Science, and Cochrane Library from their inception to January 2016, and in grey literature. Incidences (cumulative and rate) of fracture were described together using the median, according to fracture sites, the data source (administrative database or cohort and clinical registry), and fracture diagnosis method. Prevalence estimates were described separately. We included 47 studies evaluating the risk of fracture in HD, PD, and KT populations. In administrative database studies, incidence of hip fracture in HD (median 11.45 per 1000 person-years [p-y]), range: 9.3 to 13.6 was higher than in KT (median 2.6 per 1000 p-y; range 1.5 to 3.8) or in PD (median 5.2 per 1000 p-y; range 4.1 to 6.3). In dialysis (HD+PD), three studies reported a higher incidence of hip fracture than in KT. Prevalent vertebral fracture (assessed by X-rays or questionnaire) reported in HD was in a similar range as that reported in KT. Incidence of overall fracture was similar in HD and KT, from administrative databases studies, but lower in HD compared with KT, from cohorts or clinical registry studies. This systematic review suggests an important difference in fracture risk between HD, PD, and KT population, which vary according to the diagnosis method for fracture identification. © 2018 The Authors.

Abstract
OBJECTIVE Liver cirrhosis (LC) was associated with an increased risk of osteoporosis; however, the association between LC and fracture risk was inconclusive. Therefore, this systematic review and meta-analysis aims to explore the association between LC and fracture risk. DESIGN To identify related literature, a systematic search of PubMed, EMBASE, Web of science and the Cochrane Library from 1965 to July 2017 without language limitation was performed. The random-effects model described by DerSimonian and Laird was used to calculate pooled odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Eventually, 5 cohort and 3 case-control studies were identified, which included 321 035 subjects and 31 272 fracture cases. The pooled OR of the association between LC and any fracture risk, hip fracture, spine/trunk fracture and limb fracture was 1.94 (95% CI, 1.59-2.37), 2.11 (95% CI, 1.34-3.32), 2.00 (95% CI, 1.50-2.67) and 1.82 (95% CI, 1.65-2.01), respectively. CONCLUSION In conclusion, this study indicates that cirrhotic patients have an increased risk of fracture. Preventive measures should be instituted as early as possible.

Abstract
Purpose We aimed to conduct a meta-analysis of published cohort studies to evaluate the risk of hip fracture in patients undergoing dialysis or kidney transplantation (KT). Methods We identified relevant studies by searching PubMed, EMBASE and Google Scholar databases from their inception to December 31, 2017. Cohort studies evaluating risk of hip fractures in patients undergoing dialysis or KT were considered included. The methodological quality of the cohort studies was assessed using the modified Newcastle-Ottawa scale. Results In our meta-analysis of 14 retrospective cohort studies, a total of more than 1.5 million patients undergoing dialysis or KT were included, of whom more than 30,000 had hip fractures. After the merger, the proportion of hip fractures was 1.92% (95% CI, 1.38%−2.46%) with significant heterogeneity (I2=99.9%, P=0.000) in all patients, and the incidence rate of hip fractures (per 1,000 person-years) was 8.95 (95% CI, 4.05–13.85) with significant heterogeneity (I2=99.9%, P=0.000). The pooled relative risks (RR) value for dialysis patients compared with the general population were 6.35 (95% CI, 4.53–8.88) for male and 5.57 (95% CI, 4.44–6.99) for female. The pooled RR value for hemodialysis (HD) patients compared with peritoneal dialysis (PD) patients was 1.39 (95% CI, 1.13–1.70) with no heterogeneity (I2=0.0%, P=0.763). Conclusion In conclusion, the present meta-analysis reveals that about 2% of dialysis or KT patients go on to sustain a hip fracture during follow-up, with the overall hip fracture incidence rates being 8.95 per 1,000 person-years. The overall risk of hip fracture was more than 5-fold higher in dialysis patients than in the general population. Among patients on PD, HD, and KT, HD and KT patients had the highest and the lowest risk of hip fractures, respectively.

Abstract
UNLABELLED We assessed the FRAX® method in 718 hemodialyzed patients in estimating increased risk of bone major and hip fractures. Over two prospective years, statistical analysis showed that FRAX® enables a better assessment of bone major fracture risk in these patients than any of its components and other risk factors considered in the analysis. INTRODUCTION Despite the generally increased risk of bone fractures among patients with end-stage renal disease, no prediction models for identifying individuals at particular risk have been developed to date. The goal of this prospective, multicenter observational study was to assess the usefulness of the FRAX® method in comparison to all its elements considered separately, selected factors associated with renal disease and the history of falls, in estimating increased risk of low-energy major bone and hip fractures in patients undergoing chronic hemodialysis. METHODS The study included a total of 1068 hemodialysis patients, who were followed for 2 years, and finally, 718 of them were analyzed. The risk analysis included the Polish version of the FRAX® calculator (without bone mineral density), dialysis vintage, mineral metabolism disorders (serum calcium, phosphate, and parathyroid hormone), and the number of falls during the last year before the study. RESULTS Over 2 years, low-energy 30 major bone fractures were diagnosed and 13 of hip fractures among them. Area under the curve for FRAX® was 0.76 (95% CI 0.69-0.84) for major fractures and 0.70 (95% CI 0.563-0.832) for hip fractures. The AUC for major bone fractures was significantly higher than for all elements of the FRAX® calculator. In logistic regression analysis FRAX® was the strongest independent risk factor of assessment of the major bone fracture risk. CONCLUSIONS FRAX® enables a better assessment of major bone fracture risk in ESRD patients undergoing hemodialysis than any of its components and other risk factors considered in the analysis.

Abstract
Background and purpose - While development in hip fracture incidence and mortality is well examined, none has yet looked at the temporal trends regarding prevalence of co-morbidities. Therefore we investigated changes in incidence of first hip fracture, co-morbidity prevalence, 30 day- and 1-year mortality in hip fracture patients in the Danish population during the period 1999 to 2012. Patients and methods - Patients >18 years admitted with a fractured hip in Denmark between 1996 and 2012 were identified with data for the period 1999-2012 being analyzed regarding prevalence of co-morbidities, incidence, and mortality. Results - 122,923 patients were identified. Incidence in the whole population declined but sex-specific analysis showed no changes for men. For the whole study population, 30-day and 1-year mortality remained unchanged. Age at time of first hip fracture also remained unchanged. Of the included co-morbidities a decrease in prevalence of malignancy and dementia in women was found while there was an increase in the prevalence of all remaining co-morbidities, except hemi- or paraplegia for both sexes, rheumatic diseases for women, and for men diabetes with complications, myocardial infarction, AIDS/HIV, and malignancy. Interpretation - While hip fracture incidence declined for women it was unchanged for men; likewise, 30-day and 1-year mortality rates together with age at first fracture remained unchanged. When these results are compared with the relatively large increase in the prevalence of co-morbidities, it does not seem likely that the increased disease burden is affecting either the incidence or the mortality.

Abstract
The patient with chronic kidney disease (CKD) represents an extreme model for arteriosclerosis, vascular calcification, and bone disorders, all of which are also associated with ageing in the general population. These pathological features are also relevant to other common chronic health disorders such as diabetes, and chronic inflammatory and cardiovascular diseases. Although management and interventions for these major risk factors are now incorporated into most public health guidelines (eg, smoking cessation and control of bodyweight and blood pressure, as well as glucose and cholesterol concentrations), some residual cardiovascular risk is not reduced by implementation of these interventions. CKD should be regarded as an atypical disease in which both traditional and novel cardiovascular risk factors have effects on outcomes. But CKD can also be viewed conceptually as an accelerator of traditional cardiovascular risk factors. Findings from research into mineral bone disorder associated with CKD (CKD-MBD) could help the medical community to better understand the vascular actions of certain molecules, such as phosphates, fibroblast growth factor 23, parathyroid hormone, sclerostin, or vitamin D and their relevance to the management of different pathologies in the general population. Importantly, these components, which are recognised in nephrology, could help to explain residual risk of cardiovascular events in the general population. Thus, achieving a better understanding of CKD-MBDs could provide substantial insight into future treatments for arteriosclerosis and osteoporosis, which are strongly associated with ageing and morbidity in the general population.

Abstract
Chronic kidney disease (CKD) is a risk factor for fractures. The current evaluation of fracture risk is based upon the combination of various clinical factors and quantitative imaging of bone. X-ray-based tools were developed to evaluate bone status and predict fracture risk. Dual energy X-ray absorptiometry (DXA) is available worldwide. Longitudinal studies showed that low areal Bone Mineral Density (BMD) measured by DXA predicts fractures in the CKD population as it does in non uremic populations, with good specificity and moderate sensitivity. Peripheral quantitative computed tomography (pQCT) and high resolution pQCT are research tools which measure volumetric BMD at the tibia and radius. They are able to discriminate between the cortical and trabecular envelopes which are differentially affected by renal osteodystrophy. In CKD, a rapid thinning and increased porosity at the cortex is observed which is associated with increased the risk for fracture.

Abstract
Background The incidence of end stage renal disease (ESRD) in patients with systemic lupus erythematosus (SLE) is rising. However, the relationship between osteoporotic fractures and SLE in the setting of ESRD remains uninvestigated. The purpose of this study was to compare the frequency of incident osteoporotic fractures in patients with ESRD with and without SLE, to identify risk factors for fractures in patients with SLE and ESRD, and to examine the contribution of these fractures to mortality. Methods Retrospective cohort study of patients with SLE ( n = 716) and a 5% random sample of controls without SLE ( n = 4176) in the United States Renal Data System (USRDS) from years 2006-2008 enrolled in Medicare Part D. Results Fractures occurred in 10.6% ( n = 76) of patients with SLE and ESRD and 12.1% ( n = 507) of patients with ESRD without SLE ( p = 0.24). Older age (adjusted relative risk 1.02, 95% confidence interval 1.01-1.04) was associated with an increased risk for fracture in patients with SLE and ESRD. In multivariable analyses, vertebral and hip fractures more than doubled the risk for mortality. Conclusions The frequency of osteoporotic fractures in patients with SLE and ESRD is similar to the general population of patients with ESRD. Vertebral and hip fractures are significant contributors to mortality in patients with SLE and ESRD. Fracture prevention, in particular, for elderly patients with SLE and ESRD, should be considered. Summary SLE is not an independent risk factor for fractures in patients with ESRD. However, among patients with SLE and ESRD, vertebral and hip fractures are significant contributors to mortality.

Abstract
Osteoporosis is defined simply as "a skeletal disorder characterized by compromised bone strength predisposing to an increased risk of fracture. Thus, any bone lesion that causes fragility fracture is osteoporosis, which has quite heterogeneous backgrounds. Chronic kidney disease-related bone and mineral disease (CKD-MBD) is defined as "a systemic disorder of mineral and bone metabolism due to CKD, which is manifested by abnormalities in bone and mineral metabolism and/or extra-skeletal calcification". Although CKD-MBD is one of the possible causes of osteoporosis, we do not have evidences that CKD-MBD is the only or crucial determinant of bone mechanical strength in CKD patients. The risk of hip fracture is considerably high in CKD patients. Drugs that intervene in systemic mineral metabolism, indeed, lead to the improvement on bone histology in CKD patients. However, it remains unclear whether the intervention in systemic mineral metabolism also improves bone strength, today. Thus, the use of drugs that directly act on bone and the introduction of fracture liaison concept are promising strategies for fragility fracture prevention among CKD patients, as well as treatment for CKD-MBD.

Abstract
The incidence and mortality of site-specific cancers in patients with end-stage renal disease (ESRD) on maintenance dialysis have been rarely studied for Asian populations. We tapped Taiwan`s National Health Insurance Research Database to identify and recruit patients starting maintenance dialysis between 1999 and 2004. They were followed from initiation of dialysis until death, discontinuation of dialysis, or the end of 2008. We calculated the survival rate and mortality risk of dialysis patients with cancer. Of 40,833 dialysis patients, 2352 (5.8%) had been newly diagnosed with cancer. Being older, being male, and having chronic liver disease were factors associated with a higher risk for new cancer in ESRD dialysis patients. In men, liver cancer (20.63%) was the most frequent, followed by cancers of the bladder (16.88%) and kidney (11.61%). In women, bladder cancer (25.57%) was the most frequent, followed by cancers of the kidney (16.31%) and breast (11.20%). The 5-year survival rates for kidney and bladder cancer were higher than for other cancers; the survival rates for lung, stomach, and liver cancer were lower. In conclusion, the distribution of site-specific cancer was different between men and women in patients with ESRD on dialysis. More attention should be paid to teaching dialysis patients how to avoid the well-known cancer risks and carcinogens and individualized regular cancer screenings.

Abstract
PURPOSE The purpose of this paper was to review the literature concerning the treatment of chronic kidney disease-mineral bone disorder (CKD-MBD) in the elderly peritoneal dialysis (PD) patient. RESULTS Chronic kidney disease-mineral bone disorder is a major problem in the elderly PD patient, with its associated increased fracture risk, vascular calcification, and accelerated mortality fracture risk. Peritoneal dialysis, however, bears a lower risk than hemodialysis (HD). The approach to CKD-MBD prophylaxis and treatment in the elderly PD patient is similar to other CKD patients, with some important differences. Avoidance of hypercalcemia, hyperphosphatemia, and hyperparathyroidism is important, as in other CKD groups, and is generally easier to attain. Calcium-free phosphate binders are recommended for normocalcemic and hypercalcemic patients. Normalization of vitamin D levels to > 75 nmol/L (> 30 pg/L) and low-dose active vitamin D therapy is recommended for all patients. Hyperparathryoidism is to be avoided by using active vitamin D and cinacalcet. Particular attention should be paid to treating protein malnutrition. Fracture prophylaxis (exercise, use of walkers, dwelling modifications) are important. Hypomagnesemia is common in PD and can be treated with magnesium supplements. Vitamin K deficiency is also common and has been identified as a cause of vascular calcification. Accordingly, warfarin treatment for this age group is problematic. CONCLUSION While treatment principles are similar to other dialysis patient groups, physicians should be aware of the special problems of the elderly group.

Abstract
Large population registries present opportunities to understand the epidemiology of disease, study patters of care, and compare the effectiveness of different care practices. While these 'big data' tempt investigators to examine all available individuals, a targeted approach that restricts the study to an optimal sub-population may yield more relevant insights. We discuss how researchers might adapt their studies existing literature to generate additional insights.

Abstract
INTRODUCTION Fractures of the proximal femur are a significant cause of mortality and morbidity in the elderly population. Yet predictive marker of unfavourable prognosis are still lacking. Calcium phosphate product is a marker of osteo-renal dysregulation. This study investigated the role of serum calcium phosphate product (SCPP) levels as a prognostic parameter for outcome in those patients. PATIENTS AND METHODS A total of 3577 consecutive patients with diagnosed fractures of the proximal femur were included in our study (72.5% females). SCPP was divided into tertiles: <1.92mmol(2)/l(2), 1.93-2.38mmol(2)/l(2) and >2.39mmol(2)/l(2). Data collection was performed prospectively and statistical evaluation was performed retrospectively. RESULTS Mean follow up in our study group was 11.0±0.3 months. The mean age of our study group was 79.0 years (SEM ±14 years). To facilitate analysis, patients were divided in two groups: ≤84 years (64.4%) and ≥85 years (35.6%), and mortality <12 months was 12.4% (n=445). In our study population higher SCPP levels ad admission were associated with a markedly elevated mortality. In a multivariate logistic regression model adjusted for age and sex, plasma creatinine and haemoglobin at admission caused a 1.3 (CI: 1.01-1.6) for SCPP 1.93-2.38mmol(2)/l(2), and a 1.6 (CI: 1.2-2.0) for SPP >2.39mmol(2)/l(2) fold increase in overall mortality compared to patients with baseline SCPP levels (<1.92mmol(2)/l(2)) as reference category. CONCLUSION Those findings in our study population with 3577 patients over a period of 20 years proved to be, that serum Ca levels may be a good predictor for mortality in patients with fracture of the proximal femur. Further studies are required to evaluate whether these high risk patients might benefit from specific therapeutic measurements. This prognostic factor may help to increase the outcome of elderly patients with a fracture of the proximal femur.

Risk of fractures in vitiligo patients treated with phototherapy-A retrospective population-based cohort study. J Dermatol Sci 2016; 82:197-203. [PMID: 26988075 DOI: 10.1016/j.jdermsci.2016.02.010] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2015] [Revised: 02/12/2016] [Accepted: 02/26/2016] [Indexed: 12/18/2022]
Abstract
BACKGROUND Phototherapy might increase bone mineral density. However, it is unknown whether phototherapy can reduce the risk of fractures in patients with vitiligo. OBJECTIVES To investigate the effect of phototherapy on fracture risks in vitiligo patients aged 40 or older. METHODS This population-based cohort study used the 2000-2010 Taiwan National Health Insurance Research Database (NHIRD) to identify 3863 patients newly diagnosed with vitiligo between 2003 and 2009 at age ≥40 years. Study subjects were classified into three cohorts: (1) frequent phototherapy; (2) infrequent phototherapy; and (3) no phototherapy. Patients were followed until the first hip or vertebral fracture or 31 December 2010. Data were analysed using Cox regression models and also stratified by age and gender. RESULTS Frequent phototherapy decreased the fracture risks (adjusted hazard ratio (aHR)=0.32, p=0.009) in vitiligo patients. Stratification by age and gender confirmed the fracture prevention effect of frequent phototherapy in patients aged 40-64 years (aHR=0.14, p=0.016) and in female patients (aHR=0.31, p=0.024). CONCLUSIONS This study provides the first evidence that frequent phototherapy can reduce the risk of fractures among middle-aged and among female vitiligo patients.
