Cancer Care Evaluation Scale (CCES): measuring the quality of the structure and process of cancer care from the perspective of patients with cancer.

OBJECTIVE: To evaluate the quality of the structure and process of cancer care from the perspective of patients with cancer, we developed a Cancer Care Evaluation Scale. METHODS: Two anonymous online surveys of patients with cancer in Japan were conducted using a convenience sample of 400 adult cancer outpatients. RESULTS: In total, 162 patients participated in the online surveys. Factor analysis revealed that the Cancer Care Evaluation Scale had the following 12 domains: (i) relationship with physician, (ii) relationship with nurse, (iii) physical care by physician, (iv) physical care by nurse, (v) psycho-existential care, (vi) help with decision-making for patients, (vii) coordination and consistency, (viii) environment, (ix) cost, (x) availability, (xi) care for the side effects of cancer treatment by a physician, and (xii) care for the side effects of cancer treatment by a nurse. The Cancer Care Evaluation Scale was correlated with overall care satisfaction (r = 0.75), but not with the quality of life (r = 0.40). In regard to rest-retest reliability, most items showed an intraclass correlation coefficient of 0.7 or higher. CONCLUSION: The validity and reliability of the Cancer Care Evaluation Scale were confirmed, suggesting that this tool is useful for evaluating the quality of cancer care from the perspective of patients with cancer.

Low coenzyme Q10 levels in patients with acute cardiovascular disease are associated with long-term mortality.

Coenzyme Q10 (CoQ10) plays a potential role in the prevention and treatment of cardiovascular disease through improved cellular bioenergetics. Critical illness in the intensive care unit has been reported to be associated with decreased circulating CoQ10 levels, and we previously demonstrated the association of low CoQ10 levels with in-hospital mortality. However, the association of CoQ10 with the acute phase of cardiovascular disease and long-term mortality remains unclear. We enrolled 242 consecutive patients with cardiovascular disease admitted to the coronary care unit of Juntendo University Hospital to investigate the association between long-term mortality and serum CoQ10 levels. During a mean follow-up of 3.2 years, 58 patients died. The mean serum CoQ10 levels were significantly lower in the non-survivors than in the survivors (0.48 ± 0.27 vs. 0.58 ± 0.38 mg/L; p = 0.035). Compared with the patients with above-median CoQ10 levels (0.46 mg/L), the cumulative incidence of all-cause mortality was significantly higher in those with lower CoQ10 levels (p = 0.025). Multivariate Cox regression analysis further demonstrated that lower CoQ10 levels were associated with poor prognosis. Low serum CoQ10 levels during the acute phase of cardiovascular diseases were associated with long-term mortality in patients, suggesting the utility of low serum CoQ10 levels as a predictor and potential therapeutic target.

Arterial Stiffness Index and Exercise Tolerance in Patients Undergoing Cardiac Rehabilitation.

Arterial stiffness contributes to the development of cardiovascular disease (CVD). However, the relationship between the arterial stiffness and exercise tolerance in CVD patients with preserved ejection fraction (pEF) and those with reduced EF (rEF) is unclear. We enrolled 358 patients who participated in cardiac rehabilitation and underwent cardiopulmonary exercise testing at Juntendo University Hospital. After excluding 195 patients who had undergone open heart surgery and 20 patients with mid-range EF, the patients were divided into pEF (n = 99) and rEF (n = 44) groups. Arterial stiffness was assessed using arterial velocity pulse index (AVI) and arterial pressure volume index (API) at rest. The patients in the pEF group were significantly older and had a higher prevalence of coronary artery disease than the rEF group. The pEF group had significantly lower AVI levels and higher API levels than the rEF group. In the pEF group, the peak oxygen uptake (peak VO2) and the anaerobic threshold was significantly higher than those in the rEF group. The peak VO2 was significantly and negatively correlated with AVI and API in the pEF group (All, P < 0.05), but not in the rEF group. Multivariate linear regression analyses demonstrated that AVI was independently associated with peak VO2 (ß = -0.34, P < 0.05) in the pEF group. In conclusion, AVI may be a useful factor for assessing exercise tolerance, particularly in CVD patients with pEF.

Association between the tissue accumulation of advanced glycation end products and exercise capacity in cardiac rehabilitation patients.

BACKGROUND: Advanced glycation end products (AGEs) are associated with aging, diabetes mellitus (DM), and other chronic diseases. Recently, the accumulation of AGEs can be evaluated by skin autofluorescence (SAF). However, the relationship between SAF levels and exercise capacity in patients with cardiovascular disease (CVD) remains unclear. This study aimed to investigate the association between the tissue accumulation of AGEs and clinical characteristics, including exercise capacity, in patients with CVD. METHODS: We enrolled 319 consecutive CVD patients aged ≥40 years who underwent early phase II cardiac rehabilitation (CR) at our university hospital between November 2015 and September 2017. Patient background, clinical data, and the accumulation of AGEs assessed by SAF were recorded at the beginning of CR. Characteristics were compared between two patient groups divided according to the median SAF level (High SAF and Low SAF). RESULTS: The High SAF group was significantly older and exhibited a higher prevalence of DM than the Low SAF group. The sex ratio did not differ between the two groups. AGE levels showed significant negative correlations with peak oxygen uptake and ventilator efficiency (both P <  0.0001). Exercise capacity was significantly lower in the high SAF group than in the low SAF group, regardless of the presence or absence of DM (P <  0.05). A multivariate logistic regression analysis showed that SAF level was an independent factor associated with reduced exercise capacity (odds ratio 2.10; 95% confidence interval 1.13-4.05; P = 0.02). CONCLUSION: High levels of tissue accumulated AGEs, as assessed by SAF, were significantly and independently associated with reduced exercise capacity. These data suggest that measuring the tissue accumulation of AGEs may be useful in patients who have undergone CR, irrespective of whether they have DM.

Prevalence of Restless Legs Syndrome and Its Effects on Sleep and Health-Related Quality of Life in Patients With Heart Failure.

BACKGROUND: Restless legs syndrome (RLS) is a neurological disorder characterized by leg restlessness and dysesthesia. Although the relationship between RLS and heart failure (HF) has been reported, the prevalence and clinical significance of RLS in patients with HF remain to be elucidated. METHODS AND RESULTS: We enrolled consecutive patients with HF who were admitted to our institutions. RLS was diagnosed using the International Restless Legs Syndrome Study Group criteria. Subjective sleepiness, sleep quality, and quality of life (QoL) were assessed using the Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), and 8-item Short Form (SF-8), respectively. Among the 133 patients, 18 (13.6%) had RLS and were younger than those without RLS (62.4±13.4 vs 70.0±12.2, P = .017). The RLS group had significantly disrupted sleep quality and QoL, with greater PSQI score (8.0±3.2 vs 5.9±3.3, P = .015) and lower SF-8 physical component summary (PCS) score (35.6±6.5 vs 40.7±9.5, P = .031), despite similar ESS and SF-8 mental component summary scores. In the multivariable regression analysis, RLS was associated with greater PSQI (ß=0.211; P = .014) and lower PCS score (ß=-0.177; P = .045). CONCLUSION: In the patients with HF, RLS was prevalent, and sleep quality and QoL may be disrupted by RLS.

Compound-Specific Carbon Isotopic Composition of Ethanol in Brazil and US Vehicle Emissions and Wet Deposition.

Global atmospheric ethanol budget models include large uncertainties in the magnitude of ethanol emission sources and sinks. To apply stable isotope techniques to constrain ethanol emission sources, a headspace solid phase microextraction gas chromatograph-combustion-isotope ratio mass spectrometry method (HS-SPME-GC-C-IRMS) was developed to measure the carbon isotopic composition of aqueous phase ethanol at natural abundance levels (1-30 µM) with a precision of 0.4‰. The method was applied to determine the carbon isotope signatures (δ13C) of vehicle ethanol emission sources in Brazil (-12.8 ± 2.4‰) and the US (-9.8 ± 2.5‰), and to measure the carbon isotope composition of ethanol in wet deposition (-22.6 to -12.7‰). A two end-member isotope mixing model was developed using anthropogenic and biogenic end members and fractionation scenarios to estimate ethanol source contributions to wet deposition collected in Brazil and US. Mixing model results indicate anthropogenic sources contribute two and a half to four times more ethanol to the atmosphere than previously predicted in modeled global ethanol inventories. As established and developing countries continue to rapidly increase ethanol fuel consumption and subsequent emissions, understanding the magnitude of all ethanol sources and sinks will be essential for modeling future atmospheric chemistry and air quality impacts.

Low 1,5-anhydroglucitol levels are associated with long-term cardiac mortality in acute coronary syndrome patients with hemoglobin A1c levels less than 7.0.

BACKGROUND: Diabetes mellitus is considered an important risk factor for cardiovascular diseases. High hemoglobin A1c (HbA1c) levels, which indicate poor glycemic control, have been associated with occurrence of cardiovascular diseases. There are few parameters which can predict cardiovascular risk in patients with well-controlled diabetes. Low 1,5-anhydroglucitol (1,5-AG) levels are considered a clinical marker of postprandial hyperglycemia. We hypothesized that low 1,5-AG levels could predict long-term mortality in acute coronary syndrome (ACS) patients with relatively low HbA1c levels. METHODS: The present study followed a retrospective observational study design. We enrolled 388 consecutive patients with ACS admitted to the cardiac intensive care unit at the Juntendo University Hospital from January 2011 to December 2013. Levels of 1,5-AG were measured immediately before emergency coronary angiography. Patients with early stent thrombosis, no significant coronary artery stenosis, malignancy, liver cirrhosis, a history of gastrectomy, current steroid treatment, moderately to severely reduced kidney function (estimated glomerular filtration rate < 45 ml/min/1.73 m2; chronic kidney disease stage 3B, 4, and 5), HbA1c levels ≥ 7.0%, and those who received sodium glucose co-transporter 2 inhibitor therapy were excluded. RESULTS: During the 46.9-month mean follow-up period, nine patients (4.5%) died of cardiovascular disease. The 1,5-AG level was significantly lower in the cardiac death group compared with that in the survivor group (12.3 ± 5.3 vs. 19.2 ± 7.7 µg/ml, p < 0.01). Kaplan-Meier survival analysis showed that low 1,5-AG levels were associated with cardiac mortality (p = 0.02). Multivariable Cox regression analysis showed that 1,5-AG levels were an independent predictor of cardiac mortality (hazard ratio 0.76; 95% confidence interval 0.41-0.98; p = 0.03). CONCLUSION: Low 1,5-AG levels, which indicate postprandial hyperglycemia, predict long-term cardiac mortality even in ACS patients with HbA1c levels < 7.0%.

Low circulating coenzyme Q10 during acute phase is associated with inflammation, malnutrition, and in-hospital mortality in patients admitted to the coronary care unit.

Coenzyme Q10 (CoQ10) has a potential role in the prevention and treatment of heart failure through improved cellular bioenergetics. In addition, it has antioxidant, free radical scavenging, and vasodilatory effects that may be beneficial. Although critical illness in intensive care unit is associated with decreased circulating CoQ10 levels, the clinical significance of CoQ10 levels during acute phase in the patients of cardiovascular disease remains unclear. We enrolled 257 consecutive cardiovascular patients admitted to the coronary care unit (CCU). Serum CoQ10 levels were measured after an overnight fast within 24 h of admission. We examined the comparison of serum CoQ10 levels between survivors and in-hospital mortalities in patients with cardiovascular disease. Serum CoQ10 levels during the acute phase in patients admitted to the CCU had similar independent of the diagnosis. CoQ10 levels were significantly lower in patients with in-hospital mortalities than in survivors (0.43 ± 0.19 vs. 0.55 ± 0.35 mg/L, P = 0.04). In patients admitted to the CCU, CoQ10 levels were negatively associated with age and C-reactive protein levels, and positively associated with body mass index, total cholesterol, and high-density lipoprotein cholesterol levels. Low CoQ10 levels correlated with low diastolic blood pressure. Multivariate logistic regression analysis demonstrated that low CoQ10 levels were an independent predictor of in-hospital mortality. Low serum CoQ10 levels during acute phase are significantly associated with cardiovascular risk and in-hospital mortality in patients admitted to the CCU.

Decreased circulating dihomo-gamma-linolenic acid levels are associated with total mortality in patients with acute cardiovascular disease and acute decompensated heart failure.

BACKGROUND: Polyunsaturated fatty acids (PUFAs) have important roles in the pathogenesis of cardiovascular diseases. However, the clinical significance of omega-6 PUFAs in acute cardiovascular disease remains unknown. METHODS: We enrolled 417 consecutive patients with acute cardiovascular disease admitted to the cardiac intensive care unit at Juntendo University Hospital between April 2012 and October 2013. We investigated the association between serum PUFA levels and long-term mortality. Blood samples were collected after an overnight fast, within 24 h of admission. We excluded patients who received eicosapentaenoic acid therapy and those with malignancy, end-stage kidney disease, chronic hepatic disease, and connective tissue disease. RESULTS: Overall, 306 patients (mean age: 66.4 ± 15.0 years) were analysed. During the follow-up period of 2.4 ± 1.2 years, 50 patients (16.3%) died. The dihomo-gamma-linolenic acid (DGLA) levels, arachidonic acid (AA) levels, and DGLA/AA ratio were significantly lower in the nonsurvivor group than in the survivor group (DGLA: 23.2 ± 9.8 vs. 31.5 ± 12.0 µg/ml, AA: 151.1 ± 41.6 vs. 173.3 ± 51.6 µg/ml, and DGLA/AA: 0.16 ± 0.05 vs. 0.19 ± 0.06, all p < 0.01). Kaplan-Meier curves showed that survival rates were significantly higher in the higher DGLA, AA, and DGLA/AA groups than in their lower counterparts (DGLA and AA; p < 0.01, DGLA/AA; p = 0.01), although omega-3 PUFAs were not associated with prognosis. Furthermore, in patients with acute decompensated heart failure (ADHF), survival rates were significantly higher in the higher DGLA, AA, and DGLA/AA groups than in their lower counterparts (DGLA and AA; p < 0.01, DGLA/AA; p = 0.04). However, among patients with acute coronary syndrome, none of the PUFA levels were associated with prognosis. Among patients with ADHF, after controlling for confounding variables, DGLA and DGLA/AA were associated with long-term mortality [DGLA: hazard ratio (HR), 0.94; 95% confidence interval (CI), 0.88-0.99; p = 0.01 and DGLA/AA: HR, 0.87; 95% CI, 0.77-0.97; p < 0.01], whereas AA was not associated with prognosis. CONCLUSION: Low omega-6 PUFA levels, particularly DGLA, and a low DGLA/AA ratio predict long-term mortality in patients with acute cardiovascular disease and ADHF.

Successful Treatment of Congestive Heart Failure Due to Severe Aortic Valve Stenosis With Low Dose Tolvaptan in Elderly Patients.

Medical therapy for severe aortic valve stenosis (AS) is necessary for inoperable patients due to comorbid conditions. Tolvaptan (TLV), unlike other diuretics, resulted in modest changes in filling pressures associated with an increase in urine output, suggesting that TLV improves congestive heart failure (CHF) due to severe AS without hemodynamic instability.We retrospectively investigated 14 consecutive patients ≥ 80 years of age admitted due to decompensated CHF with severe AS at Juntendo University Hospital from April 2014 to November 2015. Seven of the 14 patients were treated with TLV. We examined the safety and efficacy of TLV treatment for severe AS.Mean age was 90.0 ± 6.3 years and mean aortic valve area was 0.57 ± 0.22 cm2. Urine volume at day 1 of TLV treatment was increased and urine osmolality significantly decreased at day 1 of TLV treatment (all P < 0.05). New York Heart Association classification and brain natriuretic peptide levels significantly improved 1 week after treatment and at discharge (all P < 0.05) whereas brain natriuretic peptide levels did not improve in the patients without TLV. Severe adverse events did not occur during TLV treatment. During the first 3 days, blood pressure and heart rate were relatively stable. TLV treatment did not affect serum creatinine, blood urea nitrogen, or the estimated glomerular filtration rate.In elderly patients with severe AS, TLV treatment improved CHF without hemodynamic instability. Further prospective studies are needed to assess the safety and efficacy of TLV in decompensated heart failure due to severe AS.

Family caregivers require mental health specialists for end-of-life psychosocial problems at home: a nationwide survey in Japan.

BACKGROUND: Psychological distress is problematic for patients and their family caregivers in the oncological setting. The level of stress is influenced by the health status of the patient and their family members as well as the support system for home care. However, it remains unclear how best to support distressed caregivers providing end-of-life care at home. METHODS: The present study was performed as part of the Japan Hospice and Palliative Care Evaluation study among caregivers whose family members are provided home palliative care. The caregivers were asked whether they wished to receive psychological support from mental health specialists, and factors associated with the need for psychological support were analyzed. RESULTS: Of the 1052 caregivers, 628 completed the questionnaire. As a whole, 169 subjects [27%; 23-30% (95% confidence interval)] reported needing psychological support from a mental health specialist. According to a multiple regression analysis, factors associated with the need for psychological support included (1) emotional distress due to the need to adapt to rapid worsening of the patient's condition [adjusted odds ratio: 2.62 (95% CI 1.77-3.88), p < 0.001], (2) the poor health conditions of the caregivers [2.93 (1.61-5.36), p < 0.001], and (3) having someone else available to care for the patient in place of the caregiver [0.51 (0.34-0.78), p = 0.002]. CONCLUSIONS: Psychological support is required for caregivers tending to patients at home. Further studies are needed to construct a system to provide continuous support to caregivers.

Association between depressive symptoms and changes in sleep condition in the grieving process.

PURPOSE: Bereaved families often suffer from insomnia and depression. However, the associations between depressive state and changes in sleep condition during the grieving process have not been investigated. This study aimed to clarify the prevalence of insomnia symptoms and to explore associations between present depressive state and changes in sleep condition in the grieving process in bereaved families of Japanese patients with cancer. METHODS: A cross-sectional, multicenter survey was conducted in 103 certified palliative care units. A questionnaire asking insomnia symptoms and depressive symptoms by the Center for Epidemiological Studies Depression Scale (CES-D) was mailed to bereaved families (N = 987). The association between present depressive state (CES-D ≥7) and sleep conditions in the grieving process were analyzed. RESULTS: A total of 561 families were enrolled for analysis. Fifty-three percent of family members were considered to be in a depressive state at the time of the investigation. Prevalence of past insomnia was 86.5% at "within a few weeks before the patient's death" (T1) and 84.5% at "within 6 months after the patient's death" (T2) in all bereaved family members. However, in contrast to decreased severity of insomnia between T1 and T2 in the non-depressive group (p < 0.05), severity of insomnia was unchanged in the depressive group during this period (p = 0.139). CONCLUSIONS: Insomnia symptoms are highly prevalent and may be associated with posthumous depressive state in bereaved Japanese families. These results suggest the need for careful observation of changes in sleep condition during the grieving process.

Length of home hospice care, family-perceived timing of referrals, perceived quality of care, and quality of death and dying in terminally ill cancer patients who died at home.

PURPOSE: This study aims to clarify the length of home hospice care, family-perceived timing of referrals, and their effects on the family-perceived quality of care and quality of death and dying of terminally ill cancer patients who died at home and identify the determinants of perceived late referrals. METHODS: A multicenter questionnaire survey was conducted involving 1,052 family members of cancer patients who died at home supported by 15 home-based hospice services throughout Japan. RESULTS: A total of 693 responses were analyzed (effective response rate, 66 %). Patients received home-based hospice care for a median of 35.0 days, and 8.0 % received home hospice care for less than 1 week. While 1.5 % of the families reported the timing of referrals as early, 42 % reported the timing as late or too late. The families of patients with a length of care of less than 4 weeks were more likely to regard the timing of referrals as late or too late. The patients of family members who regarded the timing of referrals as late or too late had a significantly lower perceived quality of care (effect size, 0.18; P = 0.039) and lower quality of death and dying (effect size, 0.15, P = 0.063). Independent determinants of higher likelihoods of perceived late referrals included: frequent visits to emergency departments, patient being unprepared for worsening condition, and patient having concerns about relationship with new doctor. Discharge nurse availability was independently associated with lower likelihoods of perceived late referrals. CONCLUSIONS: A significant number of bereaved families regarded the timing of referrals to home hospices as late, and the perceived timing was associated with the family-perceived quality of care and quality of death and dying. Systematic strategies to overcome the barriers related to perceived late referrals are necessary.

[Talking about home hospices with terminally ill cancer patients -- a multicenter survey of bereaved families].

INTRODUCTION: Communicating with patients is clearly an integral part of physicians' practice, and introducing home hospice care is sometimes a difficult task for oncologists. The primary aims of this study were to clarify family-reported degree of emotional distress and the necessity for improvement in communication when introducing home hospice care, and to identify factors contributing to distress levels. METHODS: A multicenter questionnaire survey was conducted involving 1,052 family members of cancer patients who died at home at 15 home-based hospice services throughout Japan. RESULTS: A total of 616 responses were analyzed(effective response rate of 60%). Fifty-nine percent of the bereaved family members reported that they were distressed or very distressed in receiving information about home hospice care, and 30% reported considerable or much improvement was necessary. There were 6 determinants of family-reported degree of emotional distress and the necessity for improvement: 1 ) Family distress was experienced when the physician stated that the disease progression defeated medicine and nothing could be done for the patient. 2 ) The physicians' explanation did not match with the state of family preparation. 3 ) There was no intimacy between hospital physician and home physician. 4 ) Physicians did not make the atmosphere relaxing enough to allow families to ask questions. 5 ) Nurses did not follow up to generate additional ideas to supplement the physician's statement. 6 ) Family members experienced pressure to make a rash decision. CONCLUSION: In receiving information about transition of home care, a considerable number of families experienced high levels of emotional distress and felt a need for improvement in the communication style. This study proposes 6 strategies to alleviate family distress.

Which quality of life instruments are preferred by cancer patients in Japan? Comparison of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 and the Functional Assessment of Cancer Therapy-General.

PURPOSE: We compared two health-related quality of life (HRQOL) instruments used for cancer patients [the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) and the Functional Assessment of Cancer Therapy-General (FACT-G)] to identify which instrument cancer patients most preferred. METHODS: Adult cancer patients who had received cancer treatments within the previous 2 years (n = 395) completed both surveys; participants assessed the importance, necessity, and appropriateness of each as an indicator of their quality of life. RESULTS: The patients significantly preferred the FACT-G over the EORTC QLQ-C30 as a more important (effect size (ES) = 0.37, P < 0.001), necessary (ES = 0.18, P < 0.001), and appropriate questionnaire (ES = 0.14, P = 0.005). The subgroups of patients with good performance status, and those who reported low levels of work disruption, significantly preferred the FACT-G more than the other. The corresponding correlation coefficients were the following: physical functioning and well-being subscale, r = 0.65; emotional functioning and well-being subscale, r = 0.60; social functioning and social/family well-being subscale, r = 0.00; and role functioning and functional well-being subscale, r = 0.41. CONCLUSIONS: We recommend using the FACT-G if the performance status of the subject is good, e.g., in outpatient or cancer survivor surveys, based on the observed patient preferences. When performance status is not good, an instrument should be chosen after considering the differences between their scale structures and social domains and based on the availability of disease-specific modules.

Impact of sleep-disordered breathing on overnight changes in arterial stiffness in patients with acute heart failure.

Overnight increases in arterial stiffness associated with sleep-disordered breathing may adversely affect patients with acute heart failure. Thus, we investigated overnight changes in arterial stiffness and their association with sleep-disordered breathing in patients hospitalized for acute heart failure. Consecutive patients with acute heart failure were enrolled. All participants underwent overnight full polysomnography following the initial improvement of acute signs and symptoms of acute heart failure. The arterial stiffness parameter, cardio-ankle vascular index (CAVI), was assessed before and after polysomnography. Overall, 60 patients (86.7% men) were analyzed. CAVI significantly increased overnight (from 8.4 ± 1.6 at night to 9.1 ± 1.7 in the morning, P < 0.001) in addition to systolic and diastolic blood pressure (from 114.1 mmHg to 121.6 mmHg, P < 0.001; and from 70.1 mmHg to 78.2 mmHg, P < 0.001, respectively). Overnight increase in CAVI (ΔCAVI ≥ 0) was observed in 42 patients (70%). The ΔCAVI ≥ 0 group was likely to have moderate-to-severe sleep-disordered breathing (i.e., apnea-hypopnea index ≥15, 55.6% vs 80.9%, P = 0.047) and greater obstructive respiratory events (29.4% vs 58.5%, P = 0.041). In multivariable analysis, moderate-to-severe sleep-disordered breathing and greater obstructive respiratory events were independently correlated with an overnight increase in CAVI (P = 0.033 and P = 0.042, respectively). In patients hospitalized for acute heart failure, arterial stiffness, as assessed by CAVI, significantly increased overnight. Moderate-to-severe sleep-disordered breathing and obstructive respiratory events may play an important role in the overnight increase in cardio-ankle vascular index.

Psychometric evaluation of the Indonesian version of the Person-centered Care Assessment Tool.

BACKGROUND: The number of Indonesian care staff working in hospitals and long-term care facilities caring for persons with dementia in Japan is increasing; however, there is no instrument available in the Indonesian language to assess their dementia care practice. OBJECTIVES: This study aimed to translate the Person-centered Care Assessment Tool (P-CAT) and evaluate its psychometric properties in a sample of Indonesian care staff working in dementia care and long-term care facilities in Japan. METHODS: This is a descriptive, methodological, and cross-sectional study. The P-CAT was translated into the Indonesian language. The draft was administered to Indonesian care staff (n = 218) working at long-term care facilities in Japan. Data were analysed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), known-group validity, internal consistency, and test-retest reliability. RESULTS: EFA showed three-factor and CFA of the three-factor indicated that the model had an acceptable fit (chi-squared statistics/degree of freedom = 1.78, comparative fit index = 0.94, root mean square error of approximation = 0.06) with a slightly different structure compared to the original P-CAT. Regarding known-group validity, the P-CAT total score was significantly higher for those who had training in dementia, who knew about person-centred care, and who showed satisfaction in the job. Internal consistency (Cronbach's α) of the total scale was 0.68 which is considered acceptable, and the test-retest reliability intraclass correlation coefficient was 0.61 which is considered moderate. CONCLUSION: The Indonesian P-CAT indicated sound validity and reliability to measure person-centred care among Indonesian care staff working in dementia care and long-term care facilities in Japan. IMPLICATION FOR PRACTICE: The development of Indonesian P-CAT allows the evaluation of dementia care, promotes and further improves person-centred care for persons with dementia provided by Indonesian care staff working in long-term care facilities in Japan.

Prognostic Value of Cheyne-Stokes Respiration and Nutritional Status in Acute Decompensated Heart Failure.

Malnutrition frequently coexists with heart failure (HF), leading to series of negative consequences. Cheyne-Stokes respiration (CSR) is predominantly detected in patients with HF. However, the effect of CSR and malnutrition on the long-term prognosis of patients with acute decompensated HF (ADHF) remains unclear. We enrolled 162 patients with ADHF (median age, 62 years; 78.4% men). The presence of CSR was assessed using polysomnography and the controlling nutritional status score was assessed to evaluate the nutritional status. Patients were divided into four groups based on CSR and malnutrition. The primary outcome was all-cause mortality. In total, 44% of patients had CSR and 67% of patients had malnutrition. The all-cause mortality rate was 26 (16%) during the 35.9 months median follow-up period. CSR with malnutrition was associated with lower survival rates (log-rank p < 0.001). Age, hemoglobin, albumin, lymphocyte count, total cholesterol, triglyceride, low-density lipoprotein cholesterol, creatinine, estimated glomerular filtration rate, B-type natriuretic peptide, administration of loop diuretics, apnea-hypopnea index and central apnea-hypopnea index were significantly different among all groups (p < 0.05). CSR with malnutrition was independently associated with all-cause mortality. In conclusion, CSR with malnutrition is associated with a high risk of all-cause mortality in patients with ADHF.

Overnight changes in uric acid, xanthine oxidoreductase and oxidative stress levels and their relationships with sleep-disordered breathing in patients with coronary artery disease.

Serum uric acid (UA) level is associated with the high cumulative incidence or prevalence of coronary artery disease (CAD), and hyperuricemia is considered as an independent risk marker for CAD. Sleep-disordered breathing (SDB) is also associated with an increased risk of CAD. Several studies have shown that SDB is associated with hyperuricemia, but the mechanisms are unclear. We measured serum levels of UA and xanthine oxidoreductase (XOR) activity and urinary levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), all of which were assessed at 6 p.m. and the following 6 a.m. in males with CAD. In addition, nocturnal pulse oximetry was performed for the night. Overall 32 eligible patients with CAD were enrolled. Serum UA levels significantly increased overnight. (5.32 ± 0.98 mg/dl to 5.46 ± 1.02 mg/dl, p < 0.001) Moreover, XOR activity and urinary 8-OHdG levels significantly increased from 6 p.m. to 6 a.m. Furthermore, 3% Oxygen desaturation index (ODI) was correlated with the overnight changes in XOR activity (r = 0.36, P = 0.047) and urinary 8-OHdG levels (r = 0.41, P = 0.02). In addition, 3%ODI was independently correlated with the changes in XOR activity (correlation coefficient, 0.36; P = 0.047) and 8-OHdG (partial correlation coefficient, 0.63; P = 0.004) in multivariable analyses. SDB severity was associated with the overnight changes in XOR activity and urinary 8-OHdG, suggesting that SDB may be associated with oxidative stress via UA production.

Diurnal Variations in Serum Uric Acid, Xanthine, and Xanthine Oxidoreductase Activity in Male Patients with Coronary Artery Disease.

Hyperuricemia is influenced by diet and can cause gout. Whether it is a potential risk factor for cardiovascular disease (CVD) remains controversial, and the mechanism is unclear. Similar to CVDs, gout attacks occur more frequently in the morning and at night. A possible reason for this is the diurnal variation in uric acid (UA), However, scientific data regarding this variation in patients with CVD are not available. Thus, we aimed to investigate diurnal variations in serum levels of UA and plasma levels of xanthine, hypoxanthine, and xanthine oxidoreductase (XOR) activity, which were measured at 18:00, 6:00, and 12:00 in male patients with coronary artery disease. Thirty eligible patients participated in the study. UA and xanthine levels significantly increased from 18:00 to 6:00 but significantly decreased from 6:00 to 12:00. By contrast, XOR activity significantly increased both from 18:00 to 6:00 and 6:00 to 12:00. Furthermore, the rates of increase in UA and xanthine levels from night to morning were significantly and positively correlated. In conclusion, UA and xanthine showed similar diurnal variations, whereas XOR activity showed different diurnal variations. The morning UA surge could be due to UA production. The mechanism involved XOR activity, but other factors were also considered.
