RESUMO
BACKGROUND: The burden of COVID-19 on healthcare workers (HCWs) is reported to be increasing, yet the psychometric scales now in use evaluate only single aspects; few measure the pandemic-specific burden on HCWs comprehensively. OBJECTIVE: To develop a scale to quantify the physical, mental, and socioeconomic burden of the COVID-19 pandemic on HCWs. DESIGN: Scale development and cross-sectional survey. PARTICIPANTS: Consenting HCWs aged ≥20. MAIN MEASURES: Development of an item-list based on literature reviews and HCW panel input, evaluation of content validity and item selection using the Delphi method, psychometric testing conducted on HCWs, validity assessment by factor analyses and hypothesis verification, internal consistency evaluation by Cronbach's alpha, test-retest analysis, and interpretability assessment. KEY RESULTS: Through the Delphi process, a 29-item pilot scale was generated. In psychometric testing, data from 863 HCWs contributed to the development of the final version of this scale, called Pandemic Burden Index twenty for HCWs (PBI-20), a 20-item scale to measure six domains: fatigue, fear of infection, inadequacy as a medical professional, mental health concerns, prejudice or discrimination, and anxiety about one's livelihood and daily life. Factor analysis showed each factor corresponded to the six domains of this scale. Hypothesis verification showed the PBI-20 total score to be moderately to highly correlated with the Short Form 36 vitality score and mental health score and with intention of turnover. The PBI-20 had good internal consistency (Cronbach's alpha 0.92). Test-retest analysis showed the intraclass correlation coefficient to be 0.70 and the minimal important change to be -7.0. CONCLUSIONS: The psychometrically sound questionnaire we developed to measure pandemic-specific burdens for HCWs provides an understanding of comprehensive burdens on HCWs and may serve to evaluate interventions to reduce the burdens.

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.

We aimed to develop and validate a new simple decision support tool (U-TEST) for diagnosis of sarcopenia in orthopaedic patients. We created seventeen candidate original questions to detect sarcopenia in orthopaedic patients with sarcopenia through expert opinions and a semi-structured interview. To derive a decision support tool, a logistic regression model with backward elimination was applied to select variables from the seventeen questions, age and underweight (BMI < 18·5 kg/m2). Sarcopenia was defined by Asian Working Group for Sarcopenia 2019 criteria. After assigning a score to each selected variable, the sum of scores was calculated. We evaluated the diagnostic performance of the new tool using a logistic regression model. A bootstrap technique was used for internal validation. Among a total of 1334 orthopaedic patients, sixty-five (4·9 %) patients were diagnosed with sarcopenia. We succeeded in developing a 'U-TEST' with scores ranging from 0 to 11 consisting of values for BMI (Underweight), age (Elderly) and two original questions ('I can't stand up from a chair without supporting myself with my arms' (Strength) and 'I feel that my arms and legs are thinner than they were in the past' (Thin)). The AUC was 0·77 (95 % CI 0·71, 0·83). With the optimal cut-off set at 3 or greater based on Youden's index, the sensitivity and the specificity were 76·1 and 63·6 %, respectively. In orthopaedic patients, our U-TEST scoring with two questions and two simple clinical variables can help to screen for sarcopenia.

BACKGROUND: To elucidate the experience of patients with cancer from diagnosis to early survivorship in Japan using a nationwide questionnaire survey, and to inform the current progress of the cancer control programs. METHODS: The survey was sent to a representative sample of adult patients with cancer identified from the national database of hospital-based cancer registries. The patients' responses were compared across three groups: patients with rare cancers, patients aged < 40 years, and patients with non-rare cancers aged ≥40 years. RESULTS: Of 20,488 patients invited to participate in the survey, 8935 (43.6%) responded. Respondents reported an average score of 7.9 out of 10 on global ratings of care. Patients with rare cancers experienced a longer time to diagnosis but the shortest time from diagnosis to first treatment (p < 0.05). Patients aged < 40 years rated worse for the majority of the survey items, especially on items that related to communication with medical staff and items referring to early survivorship. CONCLUSION: The care experienced by patients with cancer in Japan varies on the basis of age group and cancer type. Efforts should be directed to ensuring prompt access to diagnostic facilities for patients with rare cancers and providing sufficient support to younger patients.

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.

BACKGROUND: In chronic kidney disease (CKD), patients' adherence to prescriptions for diet and for medications might depend on the degree to which they have hope that they will enjoy life, and that hope could vary with the stage of CKD. The aims of this study were to quantify both the association of CKD stage with health-related hope (HR-Hope), and the association of that hope with psychological and physiological manifestations of adherence. METHODS: This was a cross-sectional study involving 461 adult CKD patients, some of whom were receiving dialysis. The main exposure was HR-Hope, measured using a recently-developed 18-item scale. The outcomes were perceived burden of fluid restriction and of diet restriction, measured using the KDQOL, and physiological manifestations of adherence (systolic and diastolic blood pressure [BP], and serum phosphorus and potassium levels). General linear models and generalized ordered logit models were fit. RESULTS: Participants at non-dialysis stage 4 and those at stage 5 had lower HR-Hope scores than did those at stage 2 or 3 (combined). Those at non-dialysis stage 5 had the lowest scores. HR-Hope scores of participants at stage 5D were similar to those of participants at stage 4, but they were lower than the scores of participants at stage 2 or 3 (combined). Higher HR-Hope scores were associated with lower perceived burdens of fluid restriction and of diet restriction (adjusted ORs per ten-point difference were 0.82 and 0.84, respectively). Higher HR-Hope scores were associated with lower systolic BP (adjusted mean difference in systolic BP per ten-point difference in HR-Hope scores was - 1.87 mmHg). In contrast, HR-Hope scores were not associated with diastolic BP, serum phosphorus levels, or serum potassium levels. CONCLUSIONS: Among CKD patients, HR-Hope is associated with disease stage, with psychological burden, and with some physiological manifestations of adherence.

BACKGROUND: Patients who have undergone esophagectomy or gastrectomy have certain dietary limitations because of changes to the alimentary tract. This study attempted to develop a psychometric scale, named "Esophago-Gastric surgery and Quality of Dietary life (EGQ-D)," for assessment of impact of upper gastrointestinal surgery on diet-targeted quality of life. METHODS: Using qualitative methods, the study team interviewed both patients and surgeons involved in esophagogastric cancer surgery, and we prepared an item pool and a draft scale. To evaluate the scale's psychometric reliability and validity, a survey involving a large number of patients was conducted. Items for the final scale were selected by factor analysis and item response theory. Cronbach's alpha was used for assessment of reliability, and correlations with the short form (SF)-12, esophagus and stomach surgery symptom scale (ES(4)), and nutritional indicators were analyzed to assess the criterion-related validity. RESULTS: Through multifaceted discussion and the pilot study, a draft questionnaire comprising 14 items was prepared, and a total of 316 patients were enrolled. On the basis of factor analysis and item response theory, six items were excluded, and the remaining eight items demonstrated strong unidimensionality for the final scale. Cronbach's alpha was 0.895. There were significant associations with all the subscale scores for SF-12, ES(4), and nutritional indicators. CONCLUSIONS: The EGQ-D scale has good contents and psychometric validity and can be used to evaluate disease-specific instrument to measure diet-targeted quality of life for postoperative patients with esophagogastric cancer.

BACKGROUND: We developed the Brief Scale for Psychiatric Problems in Orthopaedic Patients (BS-POP, physician and patient versions) and have previously shown that the BS-POP is reliable and has construct validity, criterion validity, and reproducibility. The present study aimed to proactively verify the responsiveness of the BS-POP with regard to chronic low back pain (LBP) patients. METHODS: The study subjects included 193 chronic LBP patients (81 males, 112 females; mean age 62 years) who had suffered from persistent LBP for ≥3 months. During the first test (before the treatment), the BS-POP, the Minnesota Multiphasic Personality Inventory (MMPI), the Profile of Mood States (POMS), the 36-item Short-form Health Survey version 2 (SF-36 v2), and the Roland-Morris Disability Questionnaire (RDQ) were conducted. The BS-POP, POMS, SF-36 v2, and RDQ for the third test were conducted (4-6 weeks after treatment) on all patients who had participated in the first test to determine the responsiveness of the BS-POP. The responsiveness of the BS-POP was investigated statistically. RESULTS: The total crude BS-POP scores were significantly lower for both physician and patient versions in the third test than in the first test. Moreover, the crude RDQ scores and SF-36 v2 items, physical functioning (PF), bodily pain (BP), MH, VT, and GH, and POMS items, tension-anxiety (T-A), D, F, and confusion (C) improved significantly, confirming responsiveness to treatment. DISCUSSION: The present findings indicate that the BS-POP possesses sufficient responsiveness from a computational psychology perspective. The BS-POP constitutes a tool enabling orthopaedists to easily identify psychiatric problems in orthopaedic patients.

BACKGROUND: As Japan's population ages, more frail elderly people are cared for by members of their family. The dynamics within such families are difficult to study, in part because they are difficult to quantify. We developed a scale for assessing family dynamics related to long-term care. Here we report on the development of that scale, and we present the results of reliability testing and validation testing. METHODS: Two primary-care specialists drafted questions about family dynamics, and discussed them with other primary-care physicians and clinical researchers. The final questionnaire asked about four problems or undesirable situations: disengagement (emotional distance), scapegoating (inappropriate blame), transfer of problems across generations (transfer of unnecessary burden from older to younger generations, trans-generationally displaced revenge), and undesirable behavior (co-dependence). Next, at six general-medicine clinics, doctors evaluated families that had a caregiver and a patient requiring long-term care. The results were analyzed by factor analysis. Cronbach's α was computed, and criterion-related validation tests were done with three types of criteria: relationship before caregiving, ability to do activities of daily living (ADL), and the duration of care. RESULTS: Results were obtained from 199 families. Among the caregivers, 79% were women and their mean age was 63 years. Among the patients, 71% were women and their mean age was 84 years. The results of factor analysis indicated that the scale was unidimensional. Cronbach's α was 0.73. Not having a good relationship before caregiving was associated with significantly worse family dynamics scores, as was greater dependence regarding ADL. CONCLUSIONS: We developed a scale that enables physicians to assess the dynamics of families with a patient and a family caregiver. The scale's scores are reliable and the results of validation testing were generally good. This scale holds promise as a tool both for research and for primary-care practice.

BACKGROUND: Few studies have examined the prevalence of lumbar spinal stenosis (LSS) in the general population. The purposes of this study were to estimate the prevalence of LSS and to investigate correlated factors for LSS in Japan. METHODS: A questionnaire survey was performed on 4,400 subjects selected from residents aged 40-79 years in Japan by stratified two-stage random sampling in 2010. The question items consisted of lower-limb symptoms suggestive of LSS, the diagnostic support tool for LSS (LSS-DST), demographic and lifestyle characteristics, comorbidities, the Japanese Perceived Stress Scale (JPSS), and the Mental Health Index 5 (MHI-5). Using the LSS-DST, the presence of LSS was predicted to estimate the prevalence of LSS. Logistic regression analysis was performed to examine the relationship between LSS and correlated factors. RESULTS: Questionnaires were obtained from 2,666 subjects (60.6 %), consisting of 1,264 males (47.4 %). The mean (standard deviation) age was 60.0 (10.9) years. According to the LSS-DST, 153 subjects were regarded as having LSS. The prevalence was estimated to be 5.7 %. When standardizing this value with the age distribution of the Japanese population, it was estimated that 3,650,000 Japanese subjects aged 40-79 years might have LSS using the LSS-DST. Prevalence increased with age and was particularly high in subjects aged 70-79 years, irrespective of gender. As correlated factors, an advanced age (60 years or older), diabetes mellitus, urological disorders, and osteoarthritis/fracture as comorbidities, and depressive symptoms, were associated with LSS. CONCLUSIONS: This study elucidated the prevalence of LSS and factors associated with LSS in Japan. This is the first report describing the estimated prevalence of LSS and associated factors using a strictly sampled representative population.

Introduction Establishing a scale that can easily be used to appropriately measure the impact of constipation on the quality of life in Japan is a first step toward addressing this important health issue. We developed a Japanese language version of the Constipation-Related Quality of Life scale, which has 18 items and four subscales, and then subjected it to validation testing. Methods After translation according to a standardized and commonly used procedure, the Japanese version of the Constipation-Related Quality of Life scale was administered to people in an internet-based panel, in March 2023. The participants included 1,276 adults who had constipation (median age: 60 years, 690 {54.1%} males). The outcome measures included the Constipation-Related Quality of Life scale, the Constipation Scoring System (an index of constipation severity), and the Medical Outcomes Study (MOS) eight-item short form (a measure of generic health-related quality of life). Results Confirmatory factor analysis (four-factor model) indicated that all 18 Constipation-Related Quality of Life items had sufficiently high factor loadings (0.686-0.926). Internal consistency reliability was high (Cronbach's alpha: 0.86-0.94). Scores on the social impairment subscale and on the distress subscale of the Constipation-Related Quality of Life scale were significantly worse in the participants who had worse scores on the social functioning and mental health domains, respectively, of the MOS eight-item short form, which indicates good concurrent validity. Regarding criterion-based validity, the four subscale scores differed significantly among the four constipation-severity groups. The four subscale scores were also 1.16-4.53 times more sensitive than the MOS eight-item short form's mental component score to differences among the four constipation-severity groups (relative validity: 1.16-4.53), which indicates good discriminant validity. Conclusion The Japanese version of the Constipation-Related Quality of Life scale can be used with confidence in its factor structure, its concurrent, criterion-based, and discriminant validity, and its internal consistency reliability.
RESUMO
BACKGROUND: To prepare for a longitudinal study of the effects of potassium-lowering treatment on quality of life (QOL), we quantified the validity of a new disease-specific instrument for measuring QOL, using data from patients who had hyperkalemia (HK) due to chronic kidney disease (CKD) or chronic heart failure, and were also being treated with potassium binders (PBs). METHODS: In this cross-sectional study, the participants were 98 patients at five outpatient clinics in Japan. The outcome measures were the Medical Outcomes Study 36-item short-form (SF-36), a widely used generic measure of QOL, and the Quality of Life Disease-specific Impact Scale (QDIS-7), a recently-developed disease-specific measure of QOL. Internal-consistency reliability was quantified, and factor analysis was done to confirm hypothesized QOL dimensions. Validation tests used two external criteria: CKD stage, and PB formulation. PB formulation was used because different formulations are associated with different degrees of patients' burden. Using a previously-described method, we computed the relative validity (RV) of the two measures. RESULTS: Two factor scoring of the SF-36 and one factor scoring of the QDIS-7, as standardized from previous studies, were confirmed. The RVs showed that the QDIS-7 was much more valid than the SF-36, for discriminating between groups defined clinically (by CKD stage), and also between groups defined by PB formulation. Reliability was satisfactory: 0.73-0.95 for the SF-36 and 0.86 for the QDIS-7. CONCLUSIONS: The QDIS-7 with CKD or PB attributions was more valid than the SF-36 for measuring the effects of CKD and of PB formulation on QOL.
RESUMO
INTRODUCTION: Hyperkalaemia (HK) is a frequent complication in patients with chronic kidney disease (CKD) and/or chronic heart failure (CHF). HK must be managed, both to protect patients from its direct clinical adverse outcomes and to enable treatment with disease-modifying therapies including renin-angiotensin-aldosterone system inhibitors. However, the experiences of patients undergoing treatment of HK are not clearly understood. Optimising treatment decisions and improving long-term patient management requires a better understanding of patients' quality of life (QOL). Thus, the aims of this research are: (1) to describe treatment patterns and the impact of treatment on a patient's QOL, (2) to study the relationships between treatment patterns and the impact of treatment on a patient's QOL and (3) to study the relationships between the control of serum potassium (S-K) and the impact of treatment on a patient's QOL, in patients with HK. METHODS AND ANALYSIS: This is a prospective cohort study with 6 months of follow-up in 30-40 outpatient nephrology and cardiology clinics in Japan. The participants will be 350 patients with CKD or CHF who received their first potassium binders (PB) prescription to treat HK within the previous 6 months. Medical records will be used to obtain information on S-K, on treatment of HK with PBs and with diet, and on the patients' characteristics. To assess the impact of treatment on a patient's QOL, questionnaires will be used to obtain generic health-related QOL, CKD-specific and CHF-specific QOL, and PB-specific QOL. Multivariable regression models will be used to quantify how treatment patterns and S-K control are related to the impact of treatment on a patient's QOL. ETHICS AND DISSEMINATION: Institutional review boards at all participating facilities review the study protocol. Patient consent will be obtained. The results will be published in international journals. TRIAL REGISTRATION NUMBER: NCT05297409.

Personality scales based on the five-factor model, especially the big-five scale of personality trait adjectives (Wada, 1996), are commonly used in Japan. In this study a short form of the Big-Five Scale was constructed. To avoid changes in the capacity dimension caused by the decrease in the number of items, item selection was conducted after item response theory (IRT) scales were constructed for all the items. In study 1 data was collected from 2099 participants. A generalized partial credit model was applied to the IRT model, and items were selected using the slope and location parameters for each item. Cronbach's alpha showed that the short form, as well as the five sub-scales, had sufficient reliability as a personality test. In study 2, we determined correlations with the NEO-FFI and tested the concurrent validity of the short form. The results indicate that the short form of big-five scale demonstrates sufficient reliability and validity despite the reduced number of items.

INTRODUCTION: We developed the Brief Scale for Psychiatric problems in Orthopaedic Patients (BS-POP) (doctor and patient versions). The present study aimed to proactively verify the factorial validity, internal consistency, criterion-related validity and reproducibility of the BS-POP with regard to chronic low back pain patients. METHODS: Subjects comprised 193 chronic low back pain patients. During the first test, the BS-POP, Minnesota Multiphasic Personality Inventory (MMPI), Profile of Mood States (POMS) and 36-Item Short-Form Health Survey version 2 (SF-36 v2) were conducted. In the second test, patients were asked to complete the BS-POP in order to verify BS-POP reproducibility. RESULTS: Factor analysis demonstrated the factorial validity of the BS-POP, including 1-factor structure. Internal consistency was confirmed by Cronbach's α reliability coefficients of 0.794 (doctor version) and 0.750 (patient version). Criterion-related validity was confirmed through association with the psychosocial factors of the SF-36, the MMPI, and the POMS. The correlation coefficients for the retests were r = 0.654 (doctor version) and r = 0.719 (patient version), showing reproducibility. DISCUSSION: The present findings indicate that the BS-POP possesses sufficient reliability regarding computational psychology. The BS-POP constitutes a tool enabling orthopaedists themselves to easily identify psychiatric problems in orthopaedic patients. Further study is required regarding responsiveness.

PURPOSE: The quality of recovery score QoR-40 is a recovery-specific and patient-rated questionnaire to assess the early postoperative health status of patients. However, the Japanese version of the QoR40 has not been established. The aim of this study was to validate the quality of recovery 40 Japanese version (the QoR-40J) according to the methods adopted by the International Quality of Life Assessment (IQOLA) project. METHODS: After obtaining ethics committee approval and consent, 192 general and otological surgical patients were studied. The QoR-40J was used to measure postoperative health status on day 3 and 1 month after surgery. The level of quality of life was also evaluated using a general, health-related quality of life questionnaire (Short-Form Health Survey-36 sub-scales; SF-36), at 1 month after the surgery. Psychometric analysis including the following properties: test-retest reliability, internal consistency, predictive validity, and measurement of responsiveness, was performed to validate the QoR-40J. RESULTS: Test-retest reliability (Spearman's correlation coefficient) and internal consistency (Cronbach's α) of the QoR-40J were 0.887 and 0.91, respectively. A significant relationship was observed between the total QoR-40J score and duration of hospitalization (r = -0.291) and between the global QoR-40J score and postoperative scores of the SF-36 sub-scales (physical function, ρ = 0.287; vital score, ρ = 0.349). The standardized mean of the QoR-40J, a measurement of responsiveness, was 0.70. CONCLUSION: The results of the psychometric analysis indicated that the QoR-40J has characteristics of acceptable validity, reliability, and responsiveness in clinical practice in Japan. The QoR-40J may aid in evaluating the quality of recovery after surgery or the quality of methods of anesthesia.

BACKGROUND: Understanding patient journey and burden of disease in patients with chronic thromboembolic pulmonary hypertension (CTEPH) helps improve diagnostic and treatment processes. OBJECTIVES: This study aimed to explore patient journey from time of disease onset to a definitive diagnosis and disease burden in Japanese patients with CTEPH. METHODS: A mixed-methods study exploring patient journey and disease burden of 33 Japanese patients with a definitive diagnosis of CTEPH. The patients from 2 university hospitals underwent semistructured interviews. Data were transcribed into verbatim records, and 2 independent researchers conducted thematic analyses. Data concerning patient journey were also analyzed quantitatively with supplementary use of medical records. RESULTS: Median times from initial onset of symptoms to a confirmed diagnosis and first visitation to a medical institution to a definitive diagnosis of CTEPH were 32 and 20 months, respectively. Thematic analyses found that, for patients, reasons for delay in seeking initial consultations included misattribution of symptoms to aging or lack of physical strength. For healthcare providers, reasons for delays in diagnosis included poor recognition of CTEPH and difficulty in recalling the disease as a differential diagnosis. Burdens of CTEPH were caused by physical symptoms, and mental and social issues, including restriction of daily activities owing to oxygen therapy, disappointment with the intractable nature of the disease, poor understanding of the disease by other people, and lack of social networks. CONCLUSIONS: This study highlighted physical, mental, and social burdens in patients with CTEPH and possible missed opportunities in making the diagnosis of CTEPH during the patient journey. Increasing disease awareness in healthcare providers and networking among patients may contribute to better patient care.

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.
RESUMO
BACKGROUND: The carbonaceous oral adsorbent AST-120 slows the deterioration of kidney function in patients with advanced chronic kidney disease (CKD). However, information about AST-120 in patients with less severe stages of CKD is lacking. STUDY DESIGN: Randomized controlled trial. SETTING & PARTICIPANTS: 75 medical facilities, 460 patients with CKD with serum creatinine (sCr) concentrations less than 5.0 mg/dL (not undergoing dialysis). INTERVENTION: Random assignment to either a low-protein diet and antihypertensive medication in the control group or that treatment combined with AST-120 (6 g/d). OUTCOMES & MEASUREMENTS: Composite primary end point: doubling of sCr level, increase in sCr level to 6.0 mg/dL or more, need for dialysis or transplantation, or death. SECONDARY OUTCOMES: adverse events and changes in estimated creatinine clearance (CCr) rate, proteinuria (protein in milligrams per day), and quality of life. RESULTS: Mean sCr level was 2.66 mg/dL and estimated CCr was 22.4 mL/min in both groups. During 56 weeks, numbers of primary end-point events (43 for control versus 42 for AST-120) and event-free survival (P = 0.9) did not differ between groups. Gastrointestinal adverse events were less common in the control group than the AST-120 group (2 versus 32 events). Estimated CCr decreased more in the control group than in the AST-120 group (-15% per year versus -12% per year, relative to the baseline value; [corrected] P = 0.001). Median proteinuria changed from protein of 1,162 to 1,167 mg/d in the control group versus 1,102 to 906 mg/d in the AST-120 group (P = 0.2). LIMITATION: Infrequent primary end-point events. CONCLUSION: AST-120 did not substantially slow the progression of kidney disease in patients with moderate to severe CKD during 1 year.

BACKGROUND: Various Japanese versions of the Epworth Sleepiness Scale (ESS) have been used, but none was developed via standard procedures. Here we report on the construction and testing of the developer-authorized Japanese version of the ESS (JESS). METHODS: Developing the JESS involved translations, back translations, a pilot study, and psychometric testing. We identified questions in the ESS that were difficult to answer or were inappropriate in Japan, proposed possible replacements for those questions, and tested them with analyses based on item response theory (IRT) and classical test theory. The subjects were healthy people and patients with narcolepsy, idiopathic hypersomnia, or obstructive sleep apnea syndrome. RESULTS: We identified two of our proposed questions as appropriate replacements for two problematic questions in the ESS. The JESS had very few missing data. Internal consistency reliability and test-retest reliability were high. The patients had significantly higher JESS scores than did the healthy people, and higher JESS scores were associated with worse daytime function, as measured with the Pittsburgh Sleep Quality Index. CONCLUSIONS: In Japan, the JESS provides reliable and valid information on daytime sleepiness. Researchers who use the ESS with other populations should combine their knowledge of local conditions with the results of psychometric tests.
