Preference for anti-phospholipase A2 receptor antibody assay in patients with suspected membranous nephropathy: a survey study on medical practice after publication of Japanese Guidelines for Nephrotic Syndrome 2020. Clin Exp Nephrol 2024; 28:531-538. [PMID: 38402500 DOI: 10.1007/s10157-024-02462-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Accepted: 01/12/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND International practice guidelines advocate for the use of anti-phospholipase A2 receptor (PLA2R) antibody testing to diagnose primary membranous nephropathy (pMN). This study aimed to clarify the current status of anti-PLA2R antibody testing in the diagnosis of pMN in Japan and to scrutinize the factors associated with the implementation of this antibody test. METHODS Utilizing a web-based questionnaire for nephrologists, responses were collected from 306 facilities and 427 nephrologists between November 2021 and December 2021. Preference for anti-PLA2R antibody testing was also investigated. Factors related to the experience of quantifying anti-PLA2R antibodies were estimated by generalized estimating equations using a robust analysis of variance with clusters of facilities of affiliation. RESULTS Of the 427 respondents, 140 (32.8%) had previous measurement experience at their current workplace and 165 (38.6%) had previous measurement experience overall. In pMN-suspected cases without contraindications to renal biopsy, 147 (34.4%) of the respondents opted to request anti-PLA2R antibody testing. The respondents' experience with anti-PLA2R antibody quantification at their current place of work was generally higher in university hospitals and increased with the annual number of kidney biopsies and the number of years since graduation. CONCLUSION The results of this study suggest that a significant proportion of nephrologists in Japan have no experience in performing anti-PLA2R antibody assays, and that the assays may be hampered by the limited capabilities of the current workplace and the financial burden on facilities and patients.

Contralateral knee pain exacerbation after total knee arthroplasty and its impact on functional activity. Arch Orthop Trauma Surg 2024; 144:1713-1720. [PMID: 38142260 DOI: 10.1007/s00402-023-05163-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 11/26/2023] [Indexed: 12/25/2023]
Abstract
INTRODUCTION The purposes of the present study were to (1) describe the prevalence of contralateral knee pain exacerbation after total knee arthroplasty (TKA), (2) explore the risk factors for pain exacerbation, and (3) verify the association of contralateral knee pain with future functional activity. MATERIALS AND METHOD We consecutively recruited outpatients with osteoarthritis of both knees who had primary TKA planned. The contralateral knee pain using a Numerical Rating Scale (NRS) and the functional activities subdomain of the new Knee Society Knee Scoring System (KSS) were assessed preoperatively and at 1, 3, and 6 months postoperatively. Among patients with < 5 NRS points preoperatively, we described the frequency of the contralateral knee pain exacerbation, defined as a ≥ 2-point increase from preoperative pain at each postoperative visit. An exploratory analysis was performed to identify preoperative risk factors for contralateral knee pain exacerbation. A linear mixed model was fit to examine the association of the contralateral knee pain with KSS functional activities at subsequent visits. RESULTS Among 315 patients, 14.6%, 24.1%, and 27.6% of patients experienced contralateral knee pain exacerbation at 1, 3, and 6 months postoperatively, respectively. The identified preoperative risk factors were low quadriceps strength and higher Kellgren-Lawrence grade on the non-operative knee, along with severe pain on the operative knee. The magnitude of the association between contralateral knee pain and worsening KSS functional activities increased with subsequent visits (p for interaction < 0.001). CONCLUSION The frequency and impact of pain exacerbation on the contralateral knee increase after TKA and should be carefully evaluated for a prolonged period of time.

Trust, Multidimensional Health Literacy, and Medication Adherence among Patients Undergoing Long-Term Hemodialysis. Clin J Am Soc Nephrol 2024; 19:463-471. [PMID: 38127331 PMCID: PMC11020446 DOI: 10.2215/cjn.0000000000000392] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Accepted: 12/12/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Basic health literacy and trust in physicians can influence medication adherence in patients receiving dialysis. However, how high-order health literacy is associated with medication adherence and how trust in physicians mediates this association remain unclear. We assessed the inter-relationships between health literacy, trust in physicians, and medication adherence. We investigated the mediating role of trust in physicians in the relationship between health literacy and medication adherence. METHODS This multicenter cross-sectional study included Japanese adults receiving outpatient hemodialysis at six dialysis centers. Multidimensional health literacy was measured using the 14-item Functional, Communicative, and Critical Health Literacy scale. Trust in physicians was measured using the five-item Wake Forest Physician Trust scale. Medication adherence was measured using the 12-item Adherence Starts with Knowledge scale. A series of general linear models were created to analyze the associations between health literacy and Adherence Starts Knowledge scores with and without trust in physicians. Mediation analysis was performed to determine whether trust in physicians mediated this association. RESULTS In total, 455 patients were analyzed. Higher functional and communicative health literacies were associated with less adherence difficulties (per 1-point higher: -1.79 [95% confidence interval (CI): -2.59 to -0.99] and -2.21 [95% CI: -3.45 to -0.96], respectively), whereas higher critical health literacy was associated with greater adherence difficulties (per 1-point higher: 1.69 [95% CI: 0.44 to 2.94]). After controlling for trust in physicians, the magnitude of the association between health literacies and medication adherence decreased. Trust in physicians partially mediated the association between functional or communicative health literacy and medication adherence (especially beliefs) and completely mediated the association between critical health literacy and medication adherence (especially behaviors). CONCLUSIONS Functional and communicative health literacies were positively associated with medication adherence, whereas critical health literacy was negatively associated with it. Each association was mediated by trust in physicians.

Japanese clinical practice patterns of rituximab treatment for minimal change disease in adults 2021: A web-based questionnaire survey of certified nephrologists. PLoS One 2024; 19:e0299053. [PMID: 38551948 PMCID: PMC10980199 DOI: 10.1371/journal.pone.0299053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 02/04/2024] [Indexed: 04/01/2024] Open
Abstract
BACKGROUND In Japan, rituximab (RTX) for adult-onset frequently relapsing (FR)/steroid-dependent (SD) minimal change disease (MCD) is not explicitly reimbursed by insurance, and its standard regimen has not been established. METHODS We conducted a cross-sectional web-based survey between November and December 2021. The participants were nephrologists certified by the Japanese Society of Nephrology and answered 7 items about RTX for adult MCD. Factors related to the experience of RTX administration at their facilities were estimated by generalized estimating equations. RESULTS Of 380 respondents, 181 (47.6%) reported the experience of RTX use for adult MCD at their current facilities. Those who worked at university hospitals (vs. non-university hospitals, proportion difference 13.7%) and at facilities with frequent kidney biopsies (vs. 0 cases/year, 19.2% for 1-40 cases/year; 37.9% for 41-80 cases/year; 51.9% for ≥ 81 cases/year) used RTX more frequently. Of 181 respondents, 28 (15.5%) answered that there was no insurance coverage for RTX treatment. Of 327 respondents who had the opportunity to treat MCD, which was a possible indication for RTX, 178 (54.4%) indicated withholding of RTX administration. The most common reason was the cost due to lack of insurance coverage (141, 79.2%). Regarding RTX regimens for FR/SD MCD, introduction treatment with a single body surface area-based dose of 375 mg/m2 and maintenance treatment with a 6-month interval were the most common. CONCLUSION This survey revealed the nephrologists' characteristics associated with RTX use, the barriers to RTX use, and the variation in the regimens for adult MCD in Japan.

[PMID: 38462749 DOI: 10.1111/1744-9987.14122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Revised: 02/15/2024] [Accepted: 02/21/2024] [Indexed: 03/12/2024]
Abstract
INTRODUCTION This study aimed to examine the associations of vitamin D receptor activators (VDRA) and calcimimetics use with falls. METHODS This is a prospective cohort study on hemodialysis patients in the Japan Dialysis Outcomes and Practice Patterns Study. We excluded those who were unable to walk. The associations of VDRA or calcimimetics use with falls and effect modifications by physical activity were analyzed using marginal structural models. RESULTS In total, 1875 patients were included. VDRA and calcimimetics use was not associated with falls (risk ratio [95% CI]: 1.13 [0.84-1.51] and 1.02 [0.72-1.44]). The risk ratio for falls associated with VDRA use was lower among those with poor physical activity (p for interaction <0.1). CONCLUSIONS Although vitamin D receptor activators and calcimimetics use was not associated with falls, the lower risk ratio for falls with vitamin D receptor activators use among those with poor physical activity suggests that vitamin D receptor activators use might be beneficial among these patients.

Abstract
BACKGROUND Although rituximab (RTX) is recommended by kidney disease improving global outcomes as one of the standard therapies for primary membranous nephropathy (pMN), given the constraint of insurance coverage, it is not clear how the drug is used in Japan. METHODS This cross-sectional study was conducted via a web-based survey between November and December 2021. The participants were certified nephrologists and recruited through convenience sampling. Experience with RTX for pMN was compared to experience with RTX for minimal change nephrotic syndrome (MCNS). Reasons for withholding RTX for pMN, even when it is indicated, were also investigated. Furthermore, the proportion difference in RTX experience was analyzed. RESULTS Responses from 380 nephrologists across 278 facilities were analyzed. RTX was used for pMN by 83 (21.8%), which was less than the 181 (47.6%) who had used RTX for MCNS (ratio of proportions: 0.46). RTX use for pMN was more frequent in facilities performing 41-80 and 81 or more kidney biopsies annually (vs. none) and by physicians with experience in anti-PLA2R antibody measurement. RTX administration for pMN was covered by insurance for 56 (67.5%), was facility-paid for 10 (12.0%), and was copaid by patients for 6 (7.2%). The most common reason for withholding RTX for pMN was difficulty in ensuring financing (146, 79.3%). CONCLUSIONS RTX use for pMN is less common than for MCNS but not infrequent. Treatment with RTX was more frequent in biopsy-intensive facilities, and it was fully paid by the facility or patient in one-fifth of cases.

Abstract
OBJECTIVE Person-centred care (PCC), which incorporates patients' preferences and values for medical care and their life, has been proposed in decision-making for promoting advance care planning (ACP) among patients with kidney failure. Therefore, we aimed to examine variations in PCC across facilities and the association between PCC and ACP participation. METHODS This multicentre cross-sectional study included Japanese adults undergoing outpatient haemodialysis at six dialysis centres. The main exposure was PCC, measured using the 13-item Japanese version of the Primary Care Assessment Tool-short form. The main outcome was ACP participation as defined by discussion with the attending physician or written documentation or notes regarding treatment preferences. A general linear model was used to examine the covariates of the quality of PCC. Modified Poisson regression models were used to examine the associations of ACP participation. RESULTS A total of 453 individuals were analysed; 26.3% of them participated in ACP. Higher PCC was associated with greater ACP participation in a dose-response manner (adjusted prevalence ratios for the first to fourth quartiles: 1.36, 2.31, 2.64 and 3.10, respectively) in respondents with usual source of care (USC) than in those without USC. Among the PCC subdomains, first contact, longitudinality, comprehensiveness (services provided) and community orientation were particularly associated with ACP participation. A maximum of 12.0 points of facility variation was noted in the quality of PCC. CONCLUSIONS High quality of PCC was associated with ACP participation. The substantial disparity in PCC between facilities provides an opportunity to revisit the quality improvement in PCC.

Abstract
INTRODUCTION The dose-response relationship between serum magnesium (sMg) and atrial fibrillation (AF) and the contribution of dysmagnesemia to AF among hemodialysis patients remain unknown. Hence, we examined the dose-response correlation between sMg and AF and estimated the extent of the contribution of dysmagnesemia to AF in this population. METHODS This was a nationwide cross-sectional study on the Japanese Society for Dialysis Therapy registry, also known as Japanese Renal Data Registry (JRDR), encompassing a nationwide population of dialysis centers, as of the end of 2019. Eligible participants were adult patients undergoing hemodialysis three times per week. The main exposure was sMg, categorized into seven categories (≤1.5, >1.5-≤2, >2-≤2.5, >2.5-≤3, >3-≤3.5, >3.5-≤4, and ≥4.0 mg/dL). The outcome was AF reported by dialysis facilities. The independent contribution to AF was assessed via logistic regression to generate population-attributable fractions, assuming a causal relationship between sMg and AF. RESULTS Total 165,926 patients from 2,549 facilities were investigated. AF prevalence was 7.9%. Compared with the reference (>2.5-≤3 mg/dL), lower sMg was associated with increased AF (adjusted odds ratios (ORs) (95% confidence interval, CI) of 1.49 (1.19-1.85), 1.24 (1.17-1.32), and 1.11 (1.06-1.16) for sMg of ≤1.5, >1.5-≤2.0, and >2.0-≤2.5 mg/dL categories, respectively). Elevated sMg was associated with fewer AF (adjusted OR 0.87 [95% CI, 0.79-0.96] for sMg of >3.0-≤3.5 mg/dL). The adjusted population-attributable fraction of lower sMg and higher and lower sMg for AF was 7.4% and 6.9%, respectively. An association did indeed exist between lower sMg and AF, with the lowest percentages of AF at sMg levels above the reference range for the general population. CONCLUSION Dysmagnesemia may be an important contributor to AF among adult hemodialysis patients. Further, longitudinal studies are warranted to determine whether sMg correction reduces the AF incidence.

Abstract
OBJECTIVE Differences in communication styles based on physicians' personality traits have been identified, particularly in primary care, and these physician-related factors can be important in building patient-physician trust. This study examined the effects of rheumatologists' personality traits on patients' trust in their attending rheumatologists. METHODS This cross-sectional study included adult Japanese patients with systemic lupus erythematosus (SLE) at 5 academic medical centers between June 2020 and August 2021. The exposures were the Big 5 personality traits (ie, extraversion, agreeableness, openness, conscientiousness, and emotional stability) of attending rheumatologists using the Japanese version of the 10-Item Personality Inventory scale (1-7 points each). The outcome was the patients' trust in their attending rheumatologist using the Japanese version of the 5-item Wake Forest Physician Trust Scale (0-100 points). A general linear model was fitted. RESULTS The study included 505 patients with a mean age of 46.8 years; 88.1% were women. Forty-three attending rheumatologists (mean age: 39.6 years; 23.3% female) were identified. After multivariable adjustment, higher extraversion and agreeableness were associated with higher trust (per 1-point increase, 3.76 points [95% CI 1.07-6.45] and 4.49 points [95% CI 1.74-7.24], respectively), and higher conscientiousness was associated with lower trust (per 1-point increase, -2.17 points [95% CI -3.31 to -1.03]). CONCLUSION Whereas higher extraversion and agreeableness of attending rheumatologists led to higher patient trust in their rheumatologist, overly high conscientiousness may lead to lower trust resulting from the physicians' demand of responsibility and adherence to instructions from patients with SLE.

Abstract
In patients undergoing hemodialysis, the impact of atrial fibrillation (AF) through cardiac thromboembolism on the development of ischemic stroke may be influenced by the severity of atherosclerosis present. However, there are no large-scale reports confirming whether the severity of atherosclerosis influences the relationship between AF and stroke development in patients requiring hemodialysis. We aimed to investigate the effects of atherosclerotic disease on the relationship between AF and new-onset ischemic stroke. This nationwide longitudinal study based on dialysis facilities across Japan used data collected from the Japanese Renal Data Registry at the end of 2019 and 2020. The exposure was AF at the end of 2019, identified using a resting 12-lead electrocardiography. The primary outcome was the incidence of cerebral infarction (CI) after 1 year. To examine whether the number of atherosclerotic diseases modified the association between AF and the outcome, we estimated the odds ratios (ORs) using a logistic regression model and then assessed the presence of global interaction using Wald test. Following the study criteria, data from 151,350 patients (mean age, 69 years; men, 65.2%; diabetic patients, 48.7%) were included in the final analysis. A total of 9841 patients had AF (prevalence, 6.5%). Between 2019 and 2020, 4967 patients (3.2%) developed ischemic stroke. The adjusted OR of AF for new-onset CI was 1.5, which showed a decreasing trend with an increasing number of atherosclerotic diseases; the interaction was not significant (P = 0.34). While age, diabetes mellitus, smoking, systolic blood pressure, and serum C-reactive protein concentration were positively associated with CI, intradialytic weight gain, body mass index, and serum albumin level were negatively associated. While we demonstrated the association between AF and new-onset CI among Japanese patients on hemodialysis, we failed to demonstrate the evidence that the association was attenuated with an increasing numbers of atherosclerotic complications.

Abstract
Spiritual care for patients' quality of life (QOL) and hope should be included in home medical care for patients with limited life expectancy. This study aimed to analyze the associations between estimated life expectancy, QOL, and hope among patients receiving home medical care in Japan. This multicenter cross-sectional study involved 29 home medical care facilities in Japan. Patients were categorized by estimated life expectancy, as assessed by home medical care physicians. The outcomes were QOL measured via the Quality-of-Life Scale for Elderly Patients Receiving Professional Home Care (QOL-HC: higher score indicates better QOL), the domain scores of health-related hope ("health," "role and connectedness," and "something to live for"; higher scores indicate higher levels of hope), and life functioning measured using the WHO Disability Assessment Schedule 2.0 (WHODAS 2.0; higher score indicates worse functioning and disability). QOL-HC scores were significantly higher in patients with shorter life expectancy (< 6 m vs. ≥ 1 y, adjusted mean differences: 0.7 points [95%CI 0.1 to 1.3]). Regarding health-related hope, "something to live for" scores were associated with shorter life expectancy (< 6 m vs. ≥ 1 y, -17.7 points [-34.2 to -1.2]), whereas "role and connectedness" scores did not change remarkably with shorter life expectancy (< 6 m vs. ≥ 1 y, -3.3 points [-16.4 to 9.8]). Furthermore, shorter life expectancy was associated with higher WHODAS 2.0 scores (< 6 m vs. ≥ 1 y, 19.6 points [4.3 to 34.8]). Home medical care physicians who engage in spiritual care should facilitate thoughtful dialogue with their patients by recognizing declines in life functions and hope for fulfilment, which are associated with short life expectancy.

Abstract
AIMS The aim of this cohort study was to evaluate the association between urinary levels of C-megalin, a full-length form of megalin, and kidney dysfunction progression and its dependence on the urinary albumin-creatinine ratio (UACR) in individuals with diabetes. METHODS We enrolled 1,547 individuals with diabetes who visited the ambulatory clinic at Tenri Hospital, a regional tertiary-care hospital in Tenri City, Nara Prefecture, Japan, with an estimated glomerular filtration (eGFR) of ≥ 30 mL/min/1.73 m2. The hazard ratio (HR) and 95% confidence interval (CI) were estimated using Cox proportional hazard models to examine the association between urinary C-megalin levels and eGFR decline by ≥ 40% from baseline. RESULTS Urinary C-megalin level was not associated with ≥ 40% eGFR decline in an age-, sex-, eGFR-, systolic blood pressure-, hemoglobin-, and UACR-adjusted model in the 1,547 patients enrolled in the study. However, urinary C-megalin levels were associated with a ≥ 40% decline in eGFR when accounting for the relationship between urinary C-megalin levels and UACR in the model. This association was UACR-dependent. CONCLUSIONS High urinary C-megalin levels were associated with progressive kidney dysfunction in individuals with diabetes, and this association was attenuated by high UACRs.

Abstract
INTRODUCTION Hyporesponsiveness to erythropoiesis stimulating agents (ESAs) is important problem in dialysis patients. While proton pump inhibitors (PPIs) may inhibit iron absorption, few studies have examined associations between PPIs and ESA-resistant anemia in hemodialysis patients. This study examined the associations between PPIs and ESA-resistant anemia in hemodialysis patients. METHODS The present study was a cross-sectional study using repeated 4-month observations, up to eight observations/patient, from the Japan Dialysis Outcomes and Practice Patterns Study (J-DOPPS). The primary outcome was erythropoietin resistance index (ERI). ESA dose, hemoglobin, proportion of erythropoietin-resistant anemia, transferrin saturation (TSAT), and ferritin were also examined. Linear or risk-difference regression models were used with generalized estimating equations to account for repeated measurements. RESULTS Of 1,644 patients, 867 patients had PPI prescriptions (52.7%). Patients prescribed PPI had higher ERI, higher ESA dose, and lower TSAT levels. Multivariable analysis for 12,048 four-month observations showed significantly greater ERI in PPI users (adjusted difference 0.95 IU/week/kg/[g/dL] [95% CI: 0.40-1.50]). Significant differences were also found in ESA dose (336 IU/week [95% CI: 70-602]) and the prevalence of erythropoietin-resistant anemia (3.9% [2.0-5.8%]) even after adjusted for TSAT and ferritin. Among possible mediators between the association of PPIs and anemia, TSAT was significantly different between PPI users and non-users (adjusted difference, -0.82% [95% CI: -1.56 to -0.07]). CONCLUSIONS This study showed the associations between PPI and ERI, ESA dose, and TSAT in hemodialysis patients; physicians should consider anemia's associations with PPIs in hemodialysis patients.

Abstract
OBJECTIVE Providing appropriate health information to patients with systemic lupus erythematosus (SLE) is advantageous in the treatment decision-making process. We aimed to investigate how online health information-seeking behaviors affect shared decision-making (SDM) in patients with SLE. METHODS This cross-sectional study included 464 patients with SLE from five institutions. The main exposure was time spent on the internet per day, divided into four categories (none, <1 h, 1- < 2 h, ≥2 h). Participants categorized their preferred first source of health information as physicians, the internet, or other media. The outcome was the degree of SDM measured via the 9-item Shared Decision-Making Questionnaire (SDM-Q-9). A general linear model was applied. RESULTS Compared to no internet use, longer internet use was associated with a higher SDM-Q-9 score: <1 h, 6.9 points (95% confidence interval [CI] 0.32 to 13.6) and ≥2 h, 8.75 points, (95% CI 0.61 to 16.9). The SDM-Q-9 did not differ between the individuals who chose physicians and those who chose the Internet as their preferred first source of health information (-2.1 points, 95% CI -6.7 to 2.6). Individuals who chose other media had significantly lower SDM-Q-9 scores than those who chose physicians (-7.6 points, 95% CI -13.2 to -1.9). CONCLUSIONS The present study suggests that SDM between physicians and patients is positively associated with online information-seeking behavior, with no negative influence associated with accessing the Internet before clinical consultations. Rheumatologists may need to introduce their patients to websites offering high-quality health information to establish a good physician-patient relationship for SDM.

Japanese clinical practice patterns of primary nephrotic syndrome 2021: a web-based questionnaire survey of certified nephrologists. Clin Exp Nephrol 2023; 27:767-775. [PMID: 37310570 DOI: 10.1007/s10157-023-02366-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Accepted: 05/28/2023] [Indexed: 06/14/2023]
Abstract
BACKGROUND With the publication of the "Evidence-Based Clinical Practice Guideline for Nephrotic Syndrome 2020," we examined nephrologists' adherence to the recommendations of four of its clinical questions (CQs). METHODS This was a cross-sectional web-based survey conducted between November and December 2021. The target population comprised nephrologists certified by the Japanese Society of Nephrology who were recruited using convenience sampling. The participants answered six items regarding the four CQs about adult patients with nephrotic syndrome and their characteristics. RESULTS In total, 434 respondents worked in at least 306 facilities, of whom 386 (88.9%) provided outpatient care for primary nephrotic syndrome. Of these patients, 179 (41.2%) answered that they would not measure anti- phospholipase A2 receptor antibody levels in cases of suspected primary membranous nephropathy (MN) in which kidney biopsy was not possible (CQ1). Regarding immunosuppressants as maintenance therapy after relapse of minimal change nephrotic syndrome (CQ2), cyclosporine was the most common choice (290 [72.5%] and 300 [75.0%] of 400 respondents after the first and second relapses, respectively). The most common treatment for steroid-resistant cases of primary focal segmental glomerulosclerosis (CQ3) was cyclosporine (323 of 387, 83.5%). For the initial treatment of primary MN with nephrotic-range proteinuria (CQ4), corticosteroid monotherapy was the most common choice (240 of 403, 59.6%), followed by corticosteroid and cyclosporine (114, 28.3%). CONCLUSION Gaps in recommendations and practices regarding serodiagnosis and treatment of MN (i.e., CQ1 and 4) are observed, suggesting the need to address the barriers to their insurance reimbursement and the lack of evidence behind them.

Abstract
Background Older adults commonly experience both sleep disturbances and constipation. Pathophysiological mechanisms such as inhibition of colonic peristalsis due to sympathetic activation associated with sleep disturbances have been postulated. Here, we aimed to assess the temporal association between the degree of sleep quality and the incidence of constipation. Methods We conducted a prospective cohort study of independent community-dwelling older adults aged ≥75 years (the Sukagawa Study). Using a self-administered questionnaire inquiring about awareness of own constipation or the use of laxatives in 2019 and 2020, we determined the onset of constipation. The Japanese version of the Pittsburgh Sleep Quality Index (PSQI) was used to measure sleep quality in 2019. The global PSQI score was divided into quartiles. We analyzed the association between the degree of sleep quality and the incidence of constipation using logistic regression models. Results Overall, 1,696 participants without constipation at baseline were analyzed after 1 year, of whom 823 (48.5%) were male. The mean age of participants was 79.9 years. In total, 191 participants (11.3%) developed constipation. The median (interquartile range; IQR) global PSQI score was 4 (2, 6). According to the quartiles of the global PSQI scores (0-2, 3-4, 5-6, and ≥7), 35 (7.8%), 55 (11.3%), 48 (12.8%), and 53 (13.8%), respectively, developed constipation. Compared to those with global PSQI scores of 0-2, the odds ratios, adjusted by age, sex, smoking status, alcohol status, educational level, working status, exercise, and medical history were 1.57, 1.78, and 2.02 for participants with global PSQI scores of 3-4, 5-6, and ≥7, respectively (p = 0.003 for trend). Conclusions We identified poor sleep quality as a new risk factor for developing constipation in independent, community-dwelling, older adults aged ≥75 years.

Abstract
OBJECTIVES There is a high prevalence of burnout among rheumatologists. Grit, which is defined as possessing perseverance and a passion to achieve long-term goals, is predictive of success in many professions; however, whether grit is associated with burnout remains unclear, especially among academic rheumatologists, who have multiple simultaneous responsibilities. Thus, the purpose of this study was to examine the associations between grit and self-reported burnout components-professional efficacy, exhaustion, and cynicism-in academic rheumatologists. METHODS This cross-sectional study involved 51 rheumatologists from 5 university hospitals. The exposure was grit, measured using mean scores for the 8-item Short Grit Scale (range, 1-5 [5 = extremely high grit]). The outcome measures were mean scores for 3 burnout domains (exhaustion, professional efficacy, and cynicism; range, 1-6; measured using the 16-item Maslach Burnout Inventory-General Survey). General linear models were fitted with covariates (age, sex, job title [assistant professor or higher vs lower], marital status, and having children). RESULTS Overall, 51 physicians (median age, 45 years; interquartile range, 36-57; 76% men) were included. Burnout positivity was found in 68.6% of participants (n = 35/51; 95% confidence interval [CI], 54.1, 80.9). Higher grit was associated with higher professional efficacy (per 1-point increase; 0.51 point; 95% CI, 0.18, 0.84) but not with exhaustion or cynicism. Being male and having children were associated with lower exhaustion (-0.69; 95% CI, -1.28, -0.10; p = 0.02; and -0.85; 95% CI, -1.46, -0.24; p = 0.006). Lower job title (fellow or part-time lecturer) was associated with higher cynicism (0.90; 95% CI, 0.04, 1.75; p = 0.04). CONCLUSIONS Grit is associated with higher professional efficacy among academic rheumatologists. To prevent burnout among staff, supervisors who manage academic rheumatologists should assess their staff's individual grit.

Development and external validation of the DOAT and DOATS scores: simple decision support tools to identify disease progression among nonelderly patients with mild/moderate COVID-19. BMC Pulm Med 2023; 23:312. [PMID: 37641057 PMCID: PMC10463653 DOI: 10.1186/s12890-023-02604-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Accepted: 08/10/2023] [Indexed: 08/31/2023] Open
Abstract
BACKGROUND During the fifth wave of the coronavirus disease 2019 (COVID-19) pandemic in Japan, which took place between June and September 2021, a significant number of COVID-19 cases with deterioration occurred in unvaccinated individuals < 65 years old. However, the risk factors for COVID-19 deterioration in this specific population have not yet been determined. This study developed a prediction method to identify COVID-19 patients < 65 years old who are at a high risk of deterioration. METHODS This retrospective study analyzed data from 1,675 patients < 65 years old who were admitted to acute care institutions in Fukushima with mild-to-moderate-1 COVID-19 based on the Japanese disease severity criteria prior to the fifth wave. For validation, 324 similar patients were enrolled from 3 hospitals in Yamagata. Logistic regression analyses using cluster-robust variance estimation were used to determine predictors of disease deterioration, followed by creation of risk prediction scores. Disease deterioration was defined as the initiation of medication for COVID-19, oxygen inhalation, or mechanical ventilation starting one day or later after admission. RESULTS The patients whose condition deteriorated (8.6%) tended to be older, male, have histories of smoking, and have high body temperatures, low oxygen saturation values, and comorbidities, such as diabetes/obesity and hypertension. Stepwise variable selection using logistic regression to predict COVID-19 deterioration retained comorbidities of diabetes/obesity (DO), age (A), body temperature (T), and oxygen saturation (S). Two predictive scores were created based on the optimism-corrected regression coefficients: the DOATS score, including all of the above risk factors, and the DOAT score, which was the DOATS score without oxygen saturation. In the original cohort, the areas under the receiver operating characteristic curve (AUROCs) of the DOATS and DOAT scores were 0.81 (95% confidence interval [CI] 0.77-0.85) and 0.80 (95% CI 0.76-0.84), respectively. In the validation cohort, the AUROCs for each score were both 0.76 (95% CI 0.69-0.83), and the calibration slopes were both 0.80. A decision curve analysis confirmed the clinical practicability of both scores in the validation cohort. CONCLUSIONS We established two prediction scores that can quickly evaluate the risk of COVID-19 deterioration in mild/moderate patients < 65 years old.

Abstract
AIM Dysphagia is a problem typically associated with aging. The aim was to investigate the relationship between dysphagia and motor function using a simple assessment method that can be performed in the community setting, and to promote the early detection and prevention of dysphagia. METHODS Data from the Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS) were used. Those aged ≥65 years were included. Motor function was assessed using a grip strength test, single limb standing test (SLS), and timed up and go test (TUG). Swallowing function was assessed using the Japanese version of the 10-item Eating Assessment Tool (EAT-10). The association between motor function and swallowing function was analyzed. RESULTS In total, 1732 participants were included. In logistic regression modes in which grip strength, SLS, and TUG results were included separately, the odds ratio for dysphagia increased by 1.08 (P = 0.001) for each 1-kg decrease in grip strength, and increased by 1.15 (P < 0.001) for each 1-s increase in TUG time. No association was found for SLS. In the model in which grip strength and TUG were included simultaneously, the odds ratio for dysphagia increased by 1.06 (P = 0.01) in grip strength, and increased by 1.11 (P = 0.009) in TUG time. CONCLUSION Our results suggest that skeletal muscle strength and dynamic balance function are associated with dysphagia in community-dwelling older people. Geriatr Gerontol Int 2023; ••: ••-••.

Abstract
Background and Objectives The relationship between social isolation/loneliness and oral health is unclear. This study investigated the association between social isolation/loneliness and tooth loss in older Japanese adults. Research Design and Methods This was a cross-sectional study of a population-based cohort (the Sukagawa Study); 5,490 cohort study participants aged ≥75 years and who were independent answered a self-administered questionnaire in 2018. Social isolation was defined based on the 6-item Japanese version of the Lubben Social Network Scale. Loneliness was measured by the 3-item Japanese version of the University of California, Los Angeles (UCLA) Loneliness Scale version 3. The primary outcome was tooth loss, defined as having fewer than 20 teeth. The secondary outcomes were decreased toothbrushing frequency and diminished ability to chew food. Prevalence ratios (PRs) were estimated using a modified Poisson regression analysis in 2 models-Model 1, which adjusted for age, gender, smoking status, alcohol consumption, low annual income, and short education period, and Model 2, which added history of depression, history of diabetes mellitus, history of stroke, and cognitive impairment to Model 1. Results The primary analysis included 4,645 participants. Adjusted PRs of social isolation and loneliness for tooth loss (Model 1) were 0.97 (95% confidence interval [CI] 0.92-1.01) and 1.06 (95% CI 1.01-1.12), respectively; those for decreased toothbrushing frequency were 1.13 (95% CI 0.95-1.36) and 1.56 (95% CI 1.26-1.92), respectively; and those for chewing difficulty were 1.61 (95% CI 1.06-2.43) and 2.94 (95% CI 1.91-4.53), respectively. The adjusted PRs in Model 2 demonstrated results similar to that of Model 1. Discussion and Implications Loneliness is associated with tooth loss among older adults, whereas social isolation is not. Our findings can inform plans for policymakers, professionals, and organizations to identify lonely older adults and provide social prescriptions to improve their access to oral health care services.

Abstract
OBJECTIVES We examined the frequency of cross-reactions to Rickettsia typhi in patients with Japanese spotted fever (JSF) and evaluated the differences between two rickettsiae using antibody endpoint titers. METHODS Patients' IgM and IgG titers against Rickettsia japonica and R. typhi in two phases were measured using an indirect immunoperoxidase assay at two reference centers for rickettsiosis in Japan. Cross-reaction was defined as a higher titer against R. typhi in convalescent sera than in acute sera among patients fulfilling the criteria for JSF diagnosis. The frequencies of IgM and IgG were also evaluated. RESULTS Approximately 20% of cases showed positive cross-reactions. A comparison of antibody titers revealed the difficulty in identifying some positive cases. CONCLUSIONS Cross-reactions of 20% in serodiagnosis may lead to the misclassification of rickettsial diseases. However, with the exception of some cases, we were able to successfully differentiate JSF from murine typhus using each endpoint titer.

Abstract
OBJECTIVE Patients who trust their physicians have been shown to demonstrate good medication adherence, self-management, and favorable disease outcomes. This study examines how trust in physicians is affected by functional health literacy (HL) and by broader concepts of HL, including communicative HL and critical HL, among patients with systemic lupus erythematosus (SLE). METHODS This was a cross-sectional study using baseline data from the Trust Measurement for Physicians and Patients with SLE (TRUMP2-SLE) study, an ongoing multicenter cohort study conducted at 5 academic centers. The 14-item Functional, Communicative, and Critical Health Literacy Scale assessed the 3 dimensions of HL; each item of the scale was scored on a 4-point Likert scale, ranging from 1 to 4. Outcomes were trust in one's physician and trust in physicians in general using the 5-item Wake Forest Physician Trust Scale, which ranged from 0 to 100 points. General linear models were fit. RESULTS A total of 362 patients with SLE were included. Trust in one's physician increased with higher functional and communicative HL (per 1-point increase: mean difference 3.39, 95% CI 0.39-6.39, and mean difference 5.88, 95% CI 2.04-9.71, respectively). Trust in physicians in general increased with higher communicative HL and decreased with higher critical HL (per 1-point increase: mean difference 7.09, 95% CI 2.34-11.83, and mean difference -6.88, 95% CI -11.72 to -2.04, respectively). Longer internet use was associated with both higher communicative and critical HL. CONCLUSION The findings suggest that rheumatologists need to improve their communication to match each patient's HL, which may foster trust and lead to improved self-management and outcomes in SLE. They also suggest that the formation of the rheumatologist-patient relationship may negate the effect of high critical HL in building trust.

Abstract
OBJECTIVES Although personality characteristics of patients with systemic lupus erythematosus (SLE) affect their disease activity and damage, it is unclear whether those of attending physicians affect the outcomes of patients with SLE. Grit is a personality trait for achieving long-term goals that may influence the decision-making for continuing treatment plans for patients. We aimed to evaluate the relationship between the grit of attending physicians and achievement of treatment goals in patients with SLE. METHODS This cross-sectional study was conducted at five referral hospitals. The main exposure was "consistency of interest" and "perseverance of effort" of the attending physicians, measured by the Short Grit Scale. The primary outcome was achievement of a lupus low disease activity state (LLDAS). The association between physicians' grit score and LLDAS was analyzed by generalized estimating equation (GEE) logistic regression with cluster robust variance estimation with adjustment for confounders. RESULTS The median (interquartile range) total, consistency, and perseverance scores of 37 physicians were 3.1 (2.9-3.6), 3.3 (2.8-3.8), and 3.3 (3.0-3.5), respectively. Among the 386 patients, 154 (40%) had achieved LLDAS. Low consistency score (≤2.75) in physicians was related to LLDAS achievement independently using GEE logistic regression. The score of the question "I often set a goal but later choose to pursue a different one" was significantly higher in patients achieving LLDAS. CONCLUSIONS Difficulty of attending physicians to change treatment goals might be related to lower LLDAS achievement in patients with SLE.

Abstract
OBJECTIVE Poor medication adherence among patients with systemic lupus erythematosus (SLE) is a critical problem associated with adverse outcomes. This study examined the relationship between trust in one's physician and goal-oriented thinking, hope, and medication adherence among Japanese patients with SLE who were ethnically matched to their physicians. METHODS This cross-sectional study was conducted in the rheumatology outpatient clinics at five academic centres. Patients with SLE who were prescribed oral medications were included. The main exposure was trust in one's physician measured via the 5-item Japanese version of the Wake Forest Physician Trust Scale and the 18-item Health-related Hope Scale, with each score ranging from 0 to 100 points. Medication adherence was measured using the 12-item Medication Adherence Scale with scores ranging from 5 to 60 points. A general linear model was created after adjusting for demographics, socioeconomic status, disease activity, disease duration, basic health literacy, depression, medication variables, experiencing adverse effects, and concerns regarding lupus medications. RESULTS Altogether, 373 patients with SLE were included. The mean age of the patients was 46.4 years; among them, 329 (88.2%) were women. Both trust in one's physician (per 10-point increase: 0.88, 95% confidence interval [95% CI]: 0.53-1.24) and the Health-related Hope score (per 10-point increase: 0.64, 95% CI: 0.33-0.95) were associated with better medication adherence. CONCLUSION This study demonstrated that patients' health-related hope and trust in their rheumatologist were both associated with better medication adherence in SLE.

Abstract
BACKGROUND Whether the lower phase angle associated with worse physical function is a result of pain and muscle weakness in patients with lumbar spinal stenosis (LSS) is unclear. OBJECTIVE To evaluate the association between phase angle and back pain-specific disabilities in patients with LSS. METHODS In this single-center, cross-sectional study, 491 participants with LSS were enrolled. The phase angle and back pain-specific disability were measured using bioelectrical impedance analysis and the Oswestry Disability Index, respectively. General linear models were used to examine associations between phase angle and the Oswestry Disability Index with or without adjustment for age, sex, low back and lower limb pain, numbness in the lower extremities, total fat mass, and lower limb muscle mass. RESULTS The mean (SD) phase angle was 4.4∘ (1.0∘), and the mean Oswestry Disability Index was 36.1 (14.1) points. Greater phase angles were associated with less Oswestry Disability Index points (p= 0.037) independent of fat mass, low back pain, and hip or lower limb pain. CONCLUSIONS A lower phase angle was associated with worse functional disability. Low phase angle may be an indicator of functional impairment due to low back pain associated with LSS.

Abstract
Introduction Lupus nephritis (LN) is more prevalent in patients with SLE of Asian ethnicity than in Caucasian patients. Belimumab became available in Japan in 2017 to treat patients with SLE, including those with LN. In the BLISS-LN trial (NCT01639339), belimumab showed a favourable effect on renal outcomes when combined with standard therapy (ST) starting at the induction treatment phase for active LN, but real-world effectiveness of belimumab in LN has not been extensively studied. Here we describe the protocol for the MOONLIGHT (post-Marketed effectiveness of belimumab cOhOrt and JapaN Lupus NatIonwide ReGistry (LUNA) coHorT) study, which will use data from a Japan postmarketing surveillance study and the Lupus Registry of Nationwide Institutions (LUNA) to evaluate the real-world effectiveness of belimumab plus ST versus ST alone in patients with a history of active LN who are not in the induction phase. Methods and analysis This multicentre, retrospective, observational study (GSK Study 214710) will enrol adults with SLE and a history of active LN, holding ≥3 years of complete follow-up data from the initiation of belimumab (no continuous treatment required). Data for patients with belimumab plus ST treatment (postmarketing registry data, belimumab cohort) will be compared with those for patients with ST only treatment (LUNA data, comparison cohort). Patients who discontinue/initiate belimumab after the start of the follow-up may be included in the comparison/belimumab cohort, respectively. The primary endpoint will be the occurrence of renal flares, for which belimumab’s effectiveness will be estimated using a marginal structural model to consider time-dependent treatment and confounding factors. Secondary endpoints will include change in corticosteroid dose, renal disease activity, extrarenal disease activity, disease severity/activity biomarkers, LN class changes, end-stage kidney disease events and hospitalisations. Ethics and dissemination This study will be conducted according to the Declaration of Helsinki and the local ethical guidelines. Findings will be submitted to peer-reviewed journals and presented at scientific meetings.

Abstract
BACKGROUND There is a growing need to realize high-quality end-of-life care at home that respects the patient's wishes. OBJECTIVE To examine the association between the quality of primary care and advance care planning (ACP) participation among patients receiving home-based medical care. METHODS In this multicentre, cross-sectional study, 29 home medical care clinics in Japan were included. Adult Japanese patients receiving home medical care were surveyed to assess their consideration of ACP. The quality of primary care, which reflects patient-centredness, was assessed with the Japanese version of the Primary Care Assessment Tool-Short Form (JPCAT-SF). Information on the clinical conditions that require home medical care was collected from physicians. RESULTS Of the 194 patients surveyed from 29 home medical services, 62 patients (32%) showed signs of ACP participation. Lack of opportunities was the most common reason for not participating in the ACP. In a multivariable-adjusted generalized estimating equation, primary care quality was associated with ACP participation (per 10-point increase, adjusted odds ratio: 1.96, 95% confidence interval: 1.51-2.56). In addition, all domains of the JPCAT-SF were associated with ACP participation. CONCLUSIONS Patient-centredness in home medical care facilitates the initiation of ACP participation.

Abstract
DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6 × 6 × 6 m 3 liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light. The scintillation light signal in these detectors can provide the trigger for non-beam events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP, scintillation and electroluminescence light produced by cosmic muons in the LArTPC is collected by photomultiplier tubes placed up to 7 m away from the ionizing track. In this paper, the ProtoDUNE-DP photon detection system performance is evaluated with a particular focus on the different wavelength shifters, such as PEN and TPB, and the use of Xe-doped LAr, considering its future use in giant LArTPCs. The scintillation light production and propagation processes are analyzed and a comparison of simulation to data is performed, improving understanding of the liquid argon properties.

Abstract
BackgroundIn clinical practice for systemic lupus erythematosus (SLE), the concept of “treat to target” has been introduced with an established goal of reducing glucocorticoid dose as much as possible while controlling disease activity. Although it has been shown that various personality characteristics of patients with SLE affect their disease activity and damage, it is not clear whether the personality characteristics of attending physicians affect the outcomes of patients with SLE. Grit is a personality trait characterized by perseverance and passion for achieving long-term goals.ObjectivesThis study aims to evaluate the relationship between attending physicians’ grit personality characteristics and treatment goal achievements in patients with SLE.MethodsA cross-sectional study was conducted on 386 patients with SLE in five referral hospitals in Japan. The main exposure was the “perseverance” and “consistency” (scores 1-5) of the attending physicians, as measured by the Short Grit Scale, and the primary outcome was the achievement of the Lupus Low Disease Activity Score (LLDAS). Considering the clustering of achievement of LLDAS by each attending physician, the association between attending physician’s personality and LLDAS was analyzed by logistic regression with cluster robust variance estimation. Odds ratios to assess the relationship between perseverance and consistency and LLDAS were estimated with adjustment for confounders (age, sex, disease duration, hydroxychloroquine use, immunosuppressant use, and Systemic Lupus International Collaborating Clinics-Damage Index). We used multiple imputation to handle the uncertainty caused by missing values of potential confounders on the assumption of missing at random.ResultsThe median age of the patients was 45 years (interquartile range[IQR],36-56), 88% were female, and the median disease duration was 152 months(IQR, 80-240). Thirty-seven doctors were in charge of the patients (1-79 patients/each doctor). The median age of the attending physicians was 40 years (IQR, 35-43), and 19% were female. The median perseverance and consistency scores of attending physicians were 3.1 (IQR, 3.0-3.5) and 3.3 (IQR, 2.8-3.8), respectively. Of the enrolled patients, 154 (40%) had achieved LLDAS. The attending physicians with a lower consistency score of <3 were more frequent in the patients who achieved LLDAS (40% vs. 29%, p=0.026). The lower consistency score of attending physicians was still related to LLDAS independently (adjusted odds ratio 1.63, 95% confidential interval 1.17-2.27). There was no association between the achievement of LLDAS and perseverance.ConclusionThe grit personality characteristics of the attending physician may affect the achievement of treatment goals in patients with SLE.Disclosure of InterestsKEN-EI SADA Speakers bureau: I received speaker’s fees from Glaxo Smith Kline K.K., Grant/research support from: I received a research grant from Pfizer Inc., Yoshia Miyawaki: None declared, Kenta Shidahara: None declared, Shoichi Nawachi: None declared, Yu Katayama: None declared, Yosuke ASANO: None declared, Keigo Hayashi: None declared, Keiji Ohashi: None declared, Eri Katsuyama: None declared, Takayuki Katsuyama: None declared, Mariko Narazaki: None declared, Yoshinori Matsumoto: None declared, Nao Oguro: None declared, Yuichi Ishikawa: None declared, Natsuki Sakurai: None declared, Chiharu Hidekawa: None declared, Ryusuke Yoshimi: None declared, Takanori Ichikawa: None declared, Dai Kishida: None declared, Yasuhiro Shimojima: None declared, Noriaki Kurita: None declared, Nobuyuki Yajima: None declared

Abstract
BackgroundIt is well known that providing appropriate health information to patients with systemic lupus erythematosus (SLE) has an advantage in the treatment decision making process. In modern information society the growing popularity of smartphones and social networking services, patients have more access to online health information. However, there are concerns that Internet use may inversely affect the shared decision making (SDM) process with their attending physicians if they receive inaccurate information.ObjectivesThis study aimed to investigate how online information gathering behavior affects SDM with their attending physicians.MethodsIn this cross-sectional study, information of 386 patients with SLE, which were enrolled from five Japanese institutions between June 2020 and August 2021, were analyzed. The main exposure was time spent on the Internet per day (excluding time used for working). It was divided into four categories (none, <1 hour, 1-2 hours, > 2 hours). Patients were asked to select the source of health care information they would like to access first and were categorized into physicians, the Internet, and other media sources (family and friends, healthcare professionals other than physicians, or TV and radio, etc.). Outcome was shared decision making measured via the 9-item Shared Decision Making Questionnaire (SDM-Q-9 [scores 0-100]). To assess the relationship between the time of Internet use and SDM, we fitted general linear models adjusted for age, gender, education level, household income, marital status, history of cancer, disease duration, and disease activity. Chained equations were used to impute missing values of covariates.ResultsThis study ultimately employed 334 patients whose mean age and female ratio were 45.3 years (standard deviation 13.8) and 87.7%, respectively. 68.9% of the patients indicated that they would like to access their physicians first, and 19.5% indicated that they would like to access the Internet first. Compared to patients who chose their physician as their first access to health information, there was no difference in SDM-Q-9 among patients who chose the Internet, but patients who chose other media had significantly lower SDM-Q-9 (-7.7 point, 95% confident interval [CI] -14.4 to -0.92, P=0.026). Besides, SDM-Q-9 scores were significantly lower in patients who did not use the Internet compared to those who used it for more than two hours except for their work activities (-9.6, 95%CI -18.9 to -0.26, P=0.044).ConclusionThe present study suggests that SDM between physicians and patients is positively rather than adversely associated with online information-gathering behavior. Rheumatologists also need to be aware that how patients prefer to access health information to establish a good physician-patient relationship for SDM. In addition, rheumatologists may need to introduce their patients to websites offering appropriate health information.Disclosure of InterestsNone declared

Abstract
BackgroundInformation technology has expanded the gap in patient health literacy (HL), and HL has various implications on the trust in patient-doctor relationship. Previously, only functional HL, the ability to interpret health information through reading and writing skills, has been studied in patients with SLE (1).ObjectivesWe examined how trust in physicians is affected by the broader concept of HL, including communicative HL, the ability to extract health information from communication to use, and critical HL, the ability to discern and use such information (2).MethodsThis cross-sectional study enrolled 362 SLE patients at 5 sites between June 2020 and August 2021. Three domains of HL (i.e., functional HL, communicative HL, and critical HL) were assessed using the 14-item FCCHL scale (range: 1-4 points for each domain). The outcomes were patients’ trust in their physicians and physicians in general and were measured using the Japanese version of the 5-item Wake Forest Physician Trust scales (range: 0-100 points for each scale). General linear models adjusted for age, gender, education, income, SLEDAI, disease duration, depression, and hours of Internet use were conducted. Subsequently, a series of general linear models were then fit to each of the three domains of HL to examine whether or not it was associated with the aforementioned covariates.ResultsThe median age of the patients was 45 (interquartile range [IQR],34-55), 88% were female. The median value of SLEDAI was 4 ([IQR], 2-8), Trust in one’s physician was 80 ([IQR], 70-95) and trust in physicians generally was 65 ([IQR], 50-80). Trust in one’s physician increased with higher functional and communicative HL (per 1-pt increase, 3.2 [95%CI 0.7 to 5.9]; 5.4 [95%CI 1.6 to 9.3]). Trust in doctors generally increased with higher communicative HL and decreased with higher critical HL (per 1-pt increase, 6.8 [95% CI 2.0 to 12]; -6.7 [95% CI -12 to -1.9]). Lower functional HL was associated with older age and depression, while higher HL was associated with higher educational level. Higher communicative HL and critical HL were each associated with longer Internet use.ConclusionIn patients with SLE, higher trust in one’s physician was associated with both functional and communicative HL, while higher trust in physicians generally was associated with higher communicative HL and lower critical HL. Our findings suggest that trusting relationships may be fostered by the encouragement of rheumatologists to cultivate patients’ ability to share their health problems with their physicians and family members and to obtain useful health information (i.e., communicative HL), rather than to improve their ability to discern health information (i.e., critical HL).References[1]Maheswaranathan M, Cantrell S, Eudy AM, Rogers JL, Clowse MEB, Hastings SN, et al.

Abstract
Despite the applicability of the lumbar spinal stenosis (LSS)-diagnosis support tool (DST) and the LSS-self-administered, self-reported history questionnaire (SSHQ), their diagnostic accuracy has never been compared with that of the well-known North American Spine Society (NASS) clinical description of LSS. This study aimed to compare the diagnostic accuracy of the two diagnostic tools with that of the NASS guidelines’ clinical description of LSS in a Japanese secondary care hospital setting. This multicenter cross-sectional study used data from the lumbar spinal stenosis diagnostic support tool (DISTO) project, which was conducted from December 1, 2011 to December 31, 2012. Japanese adults with low back pain (LBP) aged ≥20 years were consecutively included. The reference standard was LSS diagnosed by orthopedic physicians. The diagnostic accuracy of the two support tools was compared. Of 3,331 patients, 1,416 (42.5%) patients were diagnosed with LSS. The NASS clinical description of LSS had a sensitivity of 63.9% and specificity of 89.5%. The LSS-DST and LSS-SSHQ had sensitivities of 91.3% and 83.8% and specificities of 76.0% and 57.6%, respectively, with substantial improvements in sensitivity (P < 0.0001). Similar results were obtained when we limited included patients to those aged >60 years. These findings indicated that the LSS-DST and LSS-SSHQ were more sensitive in screening patients with LBP for a diagnosis of LSS than the NASS clinical description of LSS. This study strongly supports prioritizing the use of either of these two diagnostic support tools for screening.

Abstract
BACKGROUND Previous qualitative research has described that previous misdiagnoses may reduce patient and their families' trust in healthcare. OBJECTIVE To quantify the associations between patients or family members' misdiagnosis experiences and trust in their physician. DESIGN Cross-sectional study. PARTICIPANTS Adult Japanese people with non-communicable diseases (cancer, diabetes, depression, heart disease, and connective tissue disease), recruited using a web-based panel survey. MAIN MEASURES Surveys assessed the patient and the patient's family's experience with misdiagnosis. Trust in the respondent's current physician was measured using the Japanese version of the 11-item Trust in Physician Scale. KEY RESULTS Among 661 patients (response rate 30.1%), 23.2% had a personal history of misdiagnosis and 20.4% had a family history of misdiagnosis. In a multivariable-adjusted general linear model, patients or a family members' misdiagnosis experiences were associated with lower confidence in their current physician (mean difference -4.3, 95%CI -8.1 to -0.49 and -3.2, 95%CI -6.3 to -0.05, respectively). The impact of having a personal and a family member's experience of misdiagnosis on trust was additive, with no evidence of interaction (P for interaction = 0.494). CONCLUSIONS The patient's or family members' misdiagnosis experiences reduced trust in the patient's current physicians. Interventions specifically targeting misdiagnosed patients are needed to restore trust.

Abstract
AIMS Megalin is a multiligand receptor expressed in proximal tubular cells that reabsorbs filtered albumin and correlates cross-sectionally with albuminuria. We investigated the association between urinary C-megalin levels and the incidence of microalbuminuria in patients with diabetes mellitus. METHODS This cohort study included 752 patients with type 1 or 2 diabetes mellitus and a urinary albumin-to-creatinine (Cr) ratio (UACR) within the normoalbuminuric range (<30 mg/g Cr). The association between urinary C-megalin and persistent microalbuminuria, accounting for the possible interaction between baseline UACR and urinary C-megalin, was estimated using a Cox proportional hazards model. RESULTS During a median follow-up period of 1.99 years, 179 cases of persistent microalbuminuria were observed. The association between urinary C-megalin and persistent microalbuminuria was UACR-dependent (P for interaction < 0.001), with the highest association observed in the absence of UACR (per 100 fM/gCr of urinary C-megalin: adjusted hazard ratio, 1.13; 95% CI 1.07-1.19), gradually decreasing as UACR increased to 30 mg/g Cr. UACR dependence was confirmed by sensitivity analyses according to low-normal (<10 mg/gCr) or high-normal (10-<30 mg/gCr) UACR. CONCLUSIONS Urinary C-megalin is associated with progression to microalbuminuria, especially in those with low-normal UACR levels, and its usefulness to identify high risk patients requires further investigation.

Abstract
Background: Musculoskeletal pain could represent a psychological stressor in adolescent athletes. However, few epidemiological studies have investigated this association. Purpose: To assess the relationship between musculoskeletal pain (shoulder, elbow, wrist, and low back) and psychological stress responses in high school baseball players. Study Design: Cross-sectional study. Methods: Participants comprised male Japanese high school baseball players who had completed a questionnaire as part of their annual medical evaluation in 2016. Experiences of shoulder, elbow, wrist, and low back pain during the previous season were investigated. Pain severity was graded as 1 (mild, playing without interference), 2 (moderate, playing with interference), or 3 (severe, could not play because of pain). The Stress Response Scale–18 was used to measure stress response: low, medium, rather high, and high. Prevalence rates of shoulder, elbow, wrist, and low back pain and their association with psychological stress responses were investigated using univariate and multivariable analyses. Results: A total of 944 players (223 pitchers and 721 fielders) were included in this study. Their mean age was 16.1 ± 0.6 years, and 66% were high school juniors, while 33.6% were seniors. In pitchers, the prevalence rates during the previous year of severe (grade 3) interference with playing because of elbow, shoulder, wrist, and low back pain were 21.5% (n = 48), 19.3% (n = 43), 3.6% (n = 8), and 18.4% (n = 41), respectively, whereas in fielders, the respective prevalence rates were 17.1% (n = 123), 17.9% (n = 129), 6.7% (n = 48), and 19.3% (n = 139). After adjusting for confounding factors (playing on a top-performing team, high school grade level, and all other sites of musculoskeletal pain), the authors found significant associations in pitchers between severe experiences of elbow pain and low back pain and medium to high psychological stress responses (odds ratio, 2.64 [95% CI, 1.32-5.39], P = .006 and odds ratio, 2.32 [95% CI, 1.12-4.89], P = .024, respectively). No significant associations were seen between musculoskeletal pain and psychological stress responses in fielders. Conclusion: In the current study, elbow and low back pain were associated with stronger psychological stress responses compared with other musculoskeletal pain in high school baseball pitchers.

Abstract
BACKGROUND A family member's negative experiences with medical care have long-term effects on a patient's attitudes and emotions. However, the impact of family members' experiences on patients' trust in their own physicians and in physicians generally is poorly understood. This study aims to quantify these associations. METHODS A cross-sectional online survey involving adults with non-communicable diseases (cardiac disease, diabetes, cancer, depression, and rheumatic disease) was conducted in Japan during April 2020. The main exposure variable was dissatisfaction with the medical care that family members had received. The main outcomes were patients' (N = 661) own trust in their personal physicians and in physicians generally. The study adopted the Japanese version of the Abbreviated Wake Forest Physician Trust Scales. Both 5-item scales (general and individual physician trust) were translated and validated for the study. The total scores were transformed into a scale of 0-100 points. A series of linear mixed-effects models with consideration for clustering effect by prefectures were fit. RESULTS The results showed a lower rating for trust in physicians generally as compared to trust in the respondent's personal physician (mean 57.0 vs. 66.4 points; p < 0.001). Furthermore, dissatisfaction with a family member's medical care was associated with lower trust in physicians generally (mean difference - 9.58, 95 %CI -12.4 to -6.76). Interestingly, dissatisfaction with a family member's care was also associated with lower trust in the respondent's personal physician (mean difference - 3.19, 95 %CI -6.02 to -0.36), but the magnitude of this association was weaker. The lower trust in personal physicians may be mediated by reduced trust in physicians generally. CONCLUSIONS We suggest that physicians enquire about past patients' negative experiences, including dissatisfaction with family members' medical care, to repair hidden loss of trust, when they sense that patients doubt them or physicians generally.

[PMID: 34518920 DOI: 10.1007/s00586-021-06965-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 05/13/2021] [Accepted: 08/11/2021] [Indexed: 11/29/2022]
Abstract
PURPOSE To determine whether abnormalities of the sagittal modifiers (SMs) of the Scoliosis Research Society (SRS)-Schwab classification truly reflect back pain (BP)-specific quality of life (QOL), it is necessary to examine their dose-response relationships and to determine clinically impactful thresholds for declines in BP-specific QOL. This study aimed to analyse the continuous dose-response relationship between each SM and BP-specific QOL. METHODS This cross-sectional study, using data from a Japanese population-based cohort study, included 519 community-dwelling residents aged ≥ 50 years who participated in the annual health examination. The participants completed the Roland-Morris Disability Questionnaire (RDQ) on BP-specific QOL. Spino-pelvic alignment based on SMs was assessed by whole-spine X-ray examinations. We fitted general linear models with or without nonlinear terms to estimate the dose-response relationship between each SM and BP-specific QOL. RESULTS Pelvic tilt, pelvic incidence minus lumbar lordosis (PI-LL), and sagittal vertical axis showed dose-response relationships with BP-specific QOL measured as the RDQ score. PI-LL was most likely to predict a minimally clinically important RDQ score when its value exceeded the 90th percentile. A nonlinear relationship between PI-LL and the BP-specific QOL score was found. RDQ increased when PI-LL exceeded 10°. CONCLUSION PI-LL might be the most sensitive of the three modifiers of the SRS-Schwab classification for determining BP-specific QOL. Moreover, BP-specific QOL worsens rapidly when the compensatory mechanism against malalignment exceeds a critical value. Therefore, we suggest that traditional classifications and surgical strategies should be re-examined regarding the dose-dependent abnormalities of the SMs to develop a more reliable classification strategy.

Abstract
Abstract
Background
Little is known about the fall risk of older adults with overactive bladder (OAB), especially in the absence of urgency incontinence (UI).
Methods
This prospective cohort study included 630 community-dwelling, independent older adults 75 years old or older who attended a health check-up in 2017 with a 1-year follow-up. The associations of OAB with and without UI (OAB-wet and OAB-dry) with a fall history, and future fall risk compared to no OAB were assessed using logistic regression models. The contribution of OAB as a predictor of falls was examined using a random forest and decision tree approach.
Results
Of the 577 analyzed participants (median age 79 years), 273 were men. The prevalence of OAB-dry and OAB-wet at baseline was 15% and 14%, respectively. Multivariable logistic regression analysis revealed that both OAB-dry and OAB-wet were associated with a higher likelihood of prior falls (adjusted ORs vs no OAB 2.03 and 2.21, respectively; 95% CI 1.23–3.37 and 1.29–3.78, respectively). Among the 363 participants without a fall history, the adjusted ORs (95% CIs) of OAB-dry and OAB-wet for the occurrence of falls during the 1-year follow-up were 2.74 (1.19–6.29) and 1.35 (0.47–3.87), respectively. The tree-based approach used for all participants showed that OAB was an important predictor of falls in adults without a fall history.
Conclusions
OAB, even in the absence of UI, is an important predictor of falls in older adults with a low absolute fall risk.
Key messages
Our findings suggest that OAB is a risk factor for falls in the community-dwelling elderly irrespective of the presence of UI.

Half-integer quantized anomalous thermal Hall effect in the Kitaev material candidate α-RuCl 3. Science 2021; 373:568-572. [PMID: 34326240 DOI: 10.1126/science.aay5551] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2019] [Revised: 04/19/2020] [Accepted: 06/29/2021] [Indexed: 02/01/2023]
Abstract
Half-integer thermal quantum Hall conductance has recently been reported for the two-dimensional honeycomb material α-RuCl3 We found that the half-integer thermal Hall plateau appears even for a magnetic field with no out-of-plane components. The measured field-angular variation of the quantized thermal Hall conductance has the same sign structure as the topological Chern number of the pure Kitaev spin liquid. This observation suggests that the non-Abelian topological order associated with fractionalization of the local magnetic moments persists even in the presence of non-Kitaev interactions in α-RuCl3.

Incidence and factors associated with prescribing renin-angiotensin-system inhibitors in adult idiopathic nephrotic syndrome: A nationwide cohort study. J Clin Hypertens (Greenwich) 2021; 23:999-1007. [PMID: 33645883 PMCID: PMC8678837 DOI: 10.1111/jch.14224] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 02/02/2021] [Accepted: 02/03/2021] [Indexed: 11/27/2022]
Abstract
Angiotensin‐converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are prescribed as conservative or adjunctive therapies for adult idiopathic nephrotic syndrome. However, studies on real‐world practice patterns are scarce. This study aimed to examine the prevalence and incidence of ACEI/ARB prescription and their associated factors. This nationwide cohort study included adult Japanese patients with idiopathic nephrotic syndrome including minimal change disease (MCD), membranous nephropathy (MN), focal segmental glomerulosclerosis (FSGS), and others. The outcomes were the prevalence of ACEI/ARB prescription at baseline (date of renal biopsy or date of immunosuppressant initiation) and at 2 months after baseline. Of the 326 eligible patients, 122 (37.4%) had already been prescribed ACEIs/ARBs. Of the remaining 204 patients, 67 (32.7%) were newly prescribed within the 2‐month period. MN/FSGS (vs. MCD, adjusted odds ratio [AOR]: 4.96 [95% confidence interval {CI} 2.53–9.72] and 3.95 [95% CI 1.61–9.66], respectively), higher age (per 1‐yr increase, AOR: 1.02 [95% CI 1.00–1.04]), other hypertensive agents (AOR: 2.18 [95% CI 1.21–3.92]), antidiabetic drug (AOR: 6.57 [95% CI 1.77–24.4]) were associated with a higher prevalence of ACEI/ARB prescription. MN (vs. MCD, AOR: 6.00 [95% CI 2.57–14.0]) and higher baseline systolic blood pressure (SBP) (per 10‐mmHg increase, AOR: 1.36 [95% CI 1.09–1.70]) were associated with a higher incidence of ACEI/ARB prescription. On average, incidence of ACEI/ARB prescription increased from 19.2% to 40.8% as baseline SBP increased from 100 to 140 mmHg. Thus, Japanese nephrologists are likely to prescribe ACEIs/ARBs for nephrotic patients with MN or high baseline SBP, even below the hypertensive range.

Abstract
BACKGROUND/OBJECTIVE Reduction of muscle markers, such as creatine phosphokinase (CK), in rheumatic diseases and its association with reduced muscle mass may be of clinical importance in osteoarthritis (OA). Considering the complexity of secondary sarcopenia, clarifying the association between muscle markers and sarcopenia and disentangling the involvement of OA-related conditions are of clinical importance. We investigated the association between serum muscle biomarkers and sarcopenia among patients with OA, considering the presence of pain and inflammation. METHODS Overall, 1425 patients with knee and hip OA scheduled for joint replacement surgery were included in a single-center cross-sectional study from Screening for People Suffering Sarcopenia in Orthopedic cohort of Kobe study. Primary outcome was sarcopenia defined by 2 criteria (the Asian Working Group for Sarcopenia and the European Working Group on Sarcopenia in Older People). Pain and inflammation were measured using the numeric rating scale and serum C-reactive protein (CRP) levels, respectively. Associations between the biomarkers (serum CK, aspartate aminotransferase, alanine aminotransferase) and sarcopenia were examined using logistic regression models. RESULTS Sarcopenia by the Asian Working Group for Sarcopenia criteria was present in 4.0% of patients. In adjusted analyses, sarcopenia was negatively associated with higher serum CK levels, but not with serum aspartate aminotransferase or alanine aminotransferase levels independent of pain score and serum CRP. Neither pain score nor serum CRP level was associated with sarcopenia. Similar results were found when the European Working Group on Sarcopenia in Older People criteria were used. CONCLUSIONS Serum CK was associated with sarcopenia, suggesting the potential usefulness for sarcopenia detection regardless of pain or inflammation in OA.

Validating care-needs level against self-reported measures of functioning, disability and sarcopenia among Japanese patients receiving home medical care: The Zaitaku Evaluative Initiatives and Outcome Study. Geriatr Gerontol Int 2021; 21:229-237. [PMID: 33393206 DOI: 10.1111/ggi.14124] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Revised: 11/20/2020] [Accepted: 12/10/2020] [Indexed: 11/29/2022]
Abstract
AIM This study aimed to examine the validity of the care-needs levels classified in Japan's long-term care insurance system (LTCI-CNLs) when compared with patients' self-perceived functioning, disability and physical performance among patients receiving home medical care. METHODS This was a multicenter cross-sectional study in Japan. Patients who were receiving continuous home medical care and who could respond to the questionnaire were enrolled in this study. In addition to the LTCI-CNLs, the 12-item version of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) and the SARC-F were used to measure functioning, disability and physical performance (sarcopenia). In addition, correlations and associations of the LTCI-CNLs with the WHODAS 2.0 and SARC-F were analyzed using Spearman correlations and linear mixed models. RESULTS Data from 181 patients were included in the analyses. The LTCI-CNLs varied, ranging from support level 1 (5.5%) to care-needs level 5 (10.5%), with care-needs level 2 being the most prevalent (24.9%). Moderate correlations of the LTCI-CNLs with the WHODAS 2.0 and SARC-F were found (ρ = 0.58 and 0.44, respectively). Although WHODAS 2.0 and SARC-F scores varied within each LTCI-CNL, predicted WHODAS 2.0 and SARC-F scores increased as LTCI-CNL increased. Dementia was not associated with WHODAS 2.0 or SARC-F. CONCLUSIONS The LTCI-CNLs was associated with self-reported functioning, disability and physical performance among home medical care patients. Future studies can use the LTCI-CNLs as an outcome variable for specific care approaches or as a proxy covariate for casemix status. Geriatr Gerontol Int 2021; 21: 229-237.

Abstract
BACKGROUND/OBJECTIVES Depression and hopelessness are frequently experienced in chronic kidney disease (CKD) and are generally associated with lessened physical activity. The aim of this study was to quantify the associations between sarcopenia as determined by SARC-F with both depression and hopelessness. DESIGN AND SETTING This multicenter cohort study involving cross-sectional and longitudinal analyses was conducted in a university hospital and four general hospitals, each with a nephrology center, in Japan. PARTICIPANTS Participants consisted of 314 CKD patients (mean age 67.6), some of whom were receiving dialysis (228, 73%). MEASUREMENTS The main exposures were depression, measured using the Center for Epidemiologic Studies Depression (CES-D) questionnaire, and hopelessness, measured using a recently developed 18-item health-related hope scale (HR-Hope). The outcomes were sarcopenia at baseline and one year after, measured using the SARC-F questionnaire. Logistic regression models were applied. RESULTS The cross-sectional and longitudinal analyses included 314 and 180 patients, respectively. Eighty-nine (28.3%) patients experienced sarcopenia at baseline, and 44 (24.4%) had sarcopenia at the one-year follow-up. More hopelessness (per 10-point lower, adjusted odds ratio [AOR]: 1.33, 95% confidence interval [95% CI] 1.12-1.58), depression (AOR: 1.87, 95% CI 1.003-3.49), age (per 10-year higher, AOR: 1.70, 95% CI 1.29-2.25), being female (AOR: 2.67, 95% CI 1.43-4.98), and undergoing hemodialysis (AOR, 2.92; 95% CI, 1.41-6.05) were associated with a higher likelihood of having baseline sarcopenia. More hopelessness (per 10-point lower, AOR: 1.69, 95% CI 1.14-2.51) and depression (AOR: 4.64, 95% CI: 1.33-16.2) were associated with a higher likelihood of having sarcopenia after one year. CONCLUSIONS Among patients with different stages of CKD, both hopelessness and depression predicted sarcopenia. Provision of antidepressant therapies or goal-oriented educational programs to alleviate depression or hopelessness can be useful options to prevent sarcopenia.

Abstract
Rationale & Objective Depression is prevalent and highly associated with mortality among patients with chronic kidney disease (CKD). Psychological flexibility can be captured as acceptance in psychology, and its improvement by behavioral therapy is associated with reduced depression in some clinical settings. However, no study has been reported on patients with CKD. This study aimed to examine the association between psychological flexibility and depression in patients with CKD. Study Design Cohort study. Setting & Participants This multicenter study of 5 hospitals in Japan included patients with nondialysis stage 3-5 CKD or stage 5D CKD receiving hemodialysis or peritoneal dialysis. Predictor Psychological flexibility measured using the 7-item Acceptance and Action Questionnaire (AAQ-II). Outcomes The prevalence and incidence of depression after 1 year, which was defined by a score ≥ 16 points on the Center for Epidemiologic Studies Depression (CES-D) questionnaire. Analytical Approach Gamma regression was used in the examination of correlates of the psychological flexibility value. Modified Poisson regression models were fit for the prevalence and incidence of depression. Results The cross-sectional and longitudinal analyses included 433 and 191 patients, respectively. Lower (ie, worse) psychological flexibility levels were associated with hemodialysis and peritoneal dialysis. Higher (ie, better) psychological flexibility levels were associated with lower prevalence of depression (per 5-point increase; adjusted prevalence ratio, 0.75; 95% CI, 0.70-0.80) and lower incidence of depression (per 5-point increase; adjusted risk ratio, 0.72; 95% CI, 0.61-0.85). Limitations Depression was assessed using the CES-D questionnaire. Cultural differences may exist in the interpretation of AAQ-II scores. Conclusions Better psychological flexibility was associated with lower prevalence and incidence of depression in patients with CKD. Further studies are warranted to determine the possible prevention and treatment of depression by the development of behavioral interventions to improve psychological flexibility.
