The association between early rehabilitation and ambulatory ability at discharge in patients with hip fractures at acute-phase rehabilitation wards: a survey of the Japan Association of Rehabilitation Database.

This study aimed to examine the effectiveness of early rehabilitation in patients with femoral neck fractures admitted to acute care settings in Japan using the data registered with the Japan Association of Rehabilitation Databases (JARD). We included data for 401 patients (out of 3088 patients) aged ≥ 65 years (85 males, 316 females) from nine hospitals who sustained a femoral neck fracture between July 2005 and September 2015. Using the number of days until surgery or the number of days until the start of rehabilitation or both as the explanatory variables, and the indoor mobility at discharge as the outcome variable, we calculated the adjusted rate ratio (ARR) and 95% confidence interval (CI) using Poisson regression analysis (age, sex, cognitive impairment, concurrent symptoms, and previous history of fracture adjusted as covariates). The ARR for independent walking at the discharge of the early-rehabilitation group (starting rehabilitation within two days after the injury) was significantly higher (ARR: 2.01, 95% CI: 1.34-3.02) than that of the non-early rehabilitation group. These results suggest that early acute-phase rehabilitation after a femoral neck fracture in older patients allows for better ambulatory ability at discharge, regardless of the time to surgery.

Diagnostic performance of nutritional indicators in patients with heart failure.

AIMS: The aim of this study was to compare the diagnostic performance of the nutritional indicators, the mini nutritional assessment-short form (MNA-SF), the geriatric nutritional risk index (GNRI), and the controlling nutritional status (CONUT), in heart failure (HF) patients. METHODS AND RESULTS: Nutritional status was prospectively assessed by the aforementioned three nutritional indicators in 150 outpatients with HF who were then followed for 1 year. The prevalence of patients with the nutritional risk as assessed by the MNA-SF, GNRI, and CONUT scores was 50.0%, 13.3%, and 54.0%, respectively. There was slight agreement of nutritional risk assessment between the MNA-SF and GNRI scores (κ coefficient = 0.16), as well as the GNRI and CONUT scores (κ = 0.11), but poor agreement between the MNA-SF and CONUT scores (κ = -0.09). The CONUT score had the lowest area under the curve (AUC) for the identification of low body weight, low muscle mass, and low physical function among the three indicators (all P < 0.05). Compared with the MNA-SF score, both the GNRI and CONUT scores had lower AUCs for the identification of reduced dietary intake and weight loss (all P < 0.05). There was no significant difference in predicting all-cause mortality or HF rehospitalization among the three indicators. The prescription of statins reduced the diagnostic performance of the CONUT score, as the CONUT score includes cholesterol level assessment. CONCLUSIONS: Of the three indicators, the diagnostic ability of the MNA-SF score was the highest, and that of the CONUT score was the lowest, for the assessment of HF patient nutritional status. The CONUT score may misrepresent nutritional status, particularly in patients receiving statins.

Simple Score to Predict Treatment Response to Low-Dose Tolvaptan in Patients with Heart Failure.

The recommended starting dose of Tolvaptan for heart failure (HF) is 7.5 mg/day in Japan; the recommended dose is 3.75 mg/day for older patients to avoid excessive diuresis and hypernatremia. However, low-dose Tolvaptan may delay the release of congestion in some patients. We aimed to develop a score to predict treatment responders to 3.75 mg tolvaptan.We retrospectively analyzed 106 patients with HF who initially received 3.75 mg/day of Tolvaptan in the derivation cohort (April 2013-December 2017) and 63 patients receiving 3.75 mg/day of Tolvaptan in the validation cohort (January 2018-April 2021). Treatment responders to 3.75 mg tolvaptan did not require dose escalation of Tolvaptan for congestion relief. In multivariate analysis, blood urea nitrogen (BUN) < 39 mg/dL and hematocrit > 35% were selected as variables to predict treatment responders. These were assigned 1 point each, and patients were stratified into groups with 2 points (n = 32), 1 point (n = 39), and 0 points (n = 35). The frequency of treatment responders was 82.9% in the 2-point group, 61.5% in the 1-point group, and 34.4% in the 0-point group (P < 0.05). The predictive ability of the score was acceptable with an area under the receiving operator characteristic curve (AUC) 0.726 (P < 0.05); its performance was maintained in the validation cohort (AUC 0.733, P < 0.05).A simple score using BUN and hematocrit could identify treatment responders to 3.75 mg tolvaptan, which may help determine the appropriate starting dose of Tolvaptan, balancing efficiency with safety for older patients with HF.

Left ventricular mass index-to-QRS-voltage ratio predicts outcomes in heart failure with preserved ejection fraction.

AIMS: Increased left ventricular mass index (LVMI) disproportionate to electrocardiographic QRS voltage has been reported to be associated with cardiac fibrosis and amyloid infiltration to myocardium. This study aimed to assess whether the LVMI-to-QRS-voltage ratio predicts clinical outcomes in heart failure with preserved ejection fraction (HFpEF). METHODS AND RESULTS: The Japanese Heart Failure Syndrome with Preserved Ejection Fraction (JASPER) registry is a nationwide, observational, and prospective registration of Japanese patients hospitalized with HFpEF (EF ≥ 50%). LVMI was assessed by echocardiography using the cube formula. QRS voltage was assessed by Sokolow-Lyon voltage criteria. We divided 290 patients in the registry who met inclusion criteria into five groups according to the quintile values of their LVMI-to-QRS-voltage ratio. In the highest quintile group (≥71.8 g/m2 /mV), approximately 50% of the patients had concentric hypertrophy and 30% had eccentric hypertrophy. These patients had the highest proportion of atrial fibrillation (61.4%) and history of pacemaker implantation (12.1%) among the five groups (P < 0.05). During the mean follow-up of 587 ± 300 days, 31.4% of all patients met the composite endpoint of all-cause death or rehospitalization for HF. Even after adjustment for demographic and baseline variables, the highest quintile group had a significantly higher incidence of the composite endpoints than the lowest quintile group (<30.7 g/m2 /mV) (hazard ratio: 2.205, 95% confidence interval: 1.106-4.395, P < 0.05). CONCLUSIONS: A high LVMI-to-QRS-voltage ratio is independently associated with poor outcomes in patients with HFpEF.

Child ego state and self-care behavior change in heart failure patients.

BACKGROUND: The psychological characteristics of ego functions interfere with self-care behavior in several diseases. However, the effect of ego functions on self-care behavior after education in heart failure (HF) remains unclear. METHODS: Seventy-one HF patients were enrolled. Patients' scores on the Japanese version of the European Heart Failure Self-care Behaviour Scale (EHFScBS) were measured before and after the HF intervention, and the rate of change was used as an indicator of educational effectiveness. The Tokyo University Egogram New Ver. II was used to assess five types of ego state functions: Critical parent, Nurturing parent, Adult, Free Child, and Adapted Child (AC). RESULTS: A comparison of the five ego states showed that AC scores were significantly lower than those of the other ego states (p < 0.01). Total EHFScBS scores significantly decreased from 33 (26-39) to 16 (14-20) (p < 0.01) after the HF education, and the median rates of change in EHFScBS was -46.2%. Patients with a lower rate of change in EHFScBS were more likely to have low AC scores, as characterized by a lack of compliance and coordination, and were less likely to receive higher education (all p < 0.05). Even after adjustment for covariates, low AC scores were independently associated with low rate of change in EHFScBS (p < 0.01). CONCLUSIONS: Educational behavior change for self-care is less effective in HF patients with an ego state with low AC.

Trimethylamine N-oxide and outcomes in patients hospitalized with acute heart failure and preserved ejection fraction.

AIMS: Trimethylamine N-oxide (TMAO) is a metabolite derived from the gut microbiota. Elevated TMAO levels are associated with a poor prognosis in patients with heart failure with reduced ejection fraction. However, the prognostic effect of elevated TMAO levels on heart failure with preserved ejection fraction (HFpEF) remains unclear. METHODS AND RESULTS: We consecutively enrolled 146 patients who were hospitalized and discharged from Tottori University Hospital with the primary diagnosis of HFpEF (ejection fraction ≥ 50%). High TMAO levels were defined as those greater than the median value in the patients (20.37 µmol/L). Patients with high TMAO levels had a significantly higher prevalence of prior hospitalization for heart failure and severe renal dysfunction than those with low TMAO levels. They also had a significantly higher acylcarnitine to free carnitine ratio than those with low TMAO levels, which indicated abnormal fatty acid metabolism and relative carnitine deficiency. After adjustment for differences in the patients' background in multivariate analysis, high TMAO levels remained independently associated with a high incidence of the composite endpoints of death due to cardiac causes and hospitalization for heart failure (adjusted hazard ratio, 1.91; 95% confidence interval, 1.01 to 3.62; P < 0.05). There was a significant interaction between TMAO and nutritional status on the primary outcome, and the prognostic effect of TMAO was enhanced in patients with malnutrition. CONCLUSIONS: Elevated TMAO levels at discharge are associated with an increased risk of post-discharge cardiac events in patients with HFpEF, especially those with the complication of malnutrition.

Potentially inappropriate medications according to STOPP-J criteria and risks of hospitalization and mortality in elderly patients receiving home-based medical services.

BACKGROUND: Although potentially inappropriate medications (PIMs) have been linked to poor health outcomes, country-specific PIM criteria have not been compared. Thus, we compared the identification of PIMs between the Screening Tool for Older Person's Appropriate Prescriptions for Japanese (STOPP-J) and the 2015 American Geriatrics Society Beers Criteria in elderly patients receiving home-based medical services. METHODS: A 5-year prospective cohort study was conducted with 196 patients receiving home-based medical services. Data were collected using questionnaires and chart reviews and included detailed information on prescription medication. STOPP-J and the Beers Criteria were used to categorize PIM and non-PIM recipients. All-cause mortality and first hospitalization were compared using a multivariate Cox regression model. RESULTS: PIMs were detected in 132 patients (67.3%) by STOPP-J and in 141 patients (71.9%) by the Beers Criteria, and the mean numbers of PIMs were 1.3 ± 1.3 and 1.2 ± 1.1, respectively. The three most frequently prescribed STOPP-J PIMs were hypnotics (26.8%), diuretics (25.6%), and NSAIDs (12.6%), compared with proton pump inhibitors (PPIs) (29.8%), hypnotics (26%), and NSAIDs (8.1%) according to the Beers Criteria. STOPP-J PIMs were associated with all-cause mortality (HR 3.01, 95% CI 1.37-6.64) and hospitalization (HR 1.91, 95% CI 1.17-3.09); neither was associated with Beers Criteria PIMs. Using a modified Beers Criteria (excluding PPIs), PIMs were correlated with first hospitalization (HR 1.91, 95% CI 1.17-3.09). CONCLUSIONS: PIMs categorized by STOPP-J are associated with hospitalization and mortality in Japanese patients receiving home-based medical services. PPIs, commonly used for acid-related diseases, do not seem to have deleterious effects on health outcomes. Country-oriented, medication-specific criteria would be of considerable clinical utility.

Change in quality of life and potentially associated factors in patients receiving home-based primary care: a prospective cohort study.

BACKGROUND: The trajectories for health-related quality of life of patients receiving home-based primary care are not well identified. Our objective was to investigate changes in the quality of life (QOL) and factors that affected the QOL of patients receiving home-based primary care. METHODS: Our prospective cohort study, the Observational study of Nagoya Elderly with HOme MEdical (ONE HOME) study, recruited 184 patients undergoing home-based primary care with a 5-year follow-up period. Patients' demographic data, socioeconomic status, physical diseases, medication use, feeding intake status, nutritional status, and functional status were measured annually. The 4-item quality of life index (QOL-HC [home care]) including self-perceived and family-reported QOL ratings that had been developed and previously validated in home care settings was used. Linear regression models were used for cross-sectional and longitudinal analyses. RESULTS: The participants' mean age was 78.8 ± 10.8 years, and 55.9% of the sample was male. Most patients were frail, disabled, and/or malnourished. Self-perceived and family-reported QOL scores dropped sequentially on annual follow-ups. In the multivariate longitudinal analysis, patients who were divorced (ß = 1.74) had high baseline QOL scores (ß = 0.75) and reported higher QOL ratings. In addition, high functional dependency was associated with a low self-perceived QOL rating, with a ß-value of - 1.24 in the pre-bedridden group and - 1.39 in the bedridden group. Given the family-reported QOL rating, the baseline QOL scores (ß = 0.50) and Mini-Nutritional Assessment-Short-Form scores (ß = 0.37) were found to have positive associations with the QOL rating. CONCLUSIONS: For the disabled receiving home-based primary care, independent functional status and divorce were positively associated with better self-perceived QOL, whereas nutritional status was correlated with better family-reported QOL.

[Agreement in the responses to self-reported and proxy-reported versions of QOL-HC: a new quality-of-life scale for patients receiving home-based medical care].

AIM: We developed quality-of-life (QOL) scales for patients receiving home medical care. The objective of this study was to examine the agreement between the scores of the scales answered by patients and those answered by their proxy, as cognitive decline may interfere with one's ability to understand complex topics, such as the QOL. METHODS: Participants were pairs of patients receiving home medical care and their proxy. The patients were asked to complete self-reported QOL scales (QOL-HC), and their proxies were asked to complete proxy-reported versions of the QOL scales (QOL-HC for caregivers). We then statistically examined the extent of agreement between the self- and proxy-reported QOL-HC scores using contingency tables and Spearman's rank correlation coefficient. The SPSS software program, version 24, was used for all statistical analyses. RESULTS: The concordance rate between patients and caregivers for questions 1 ( "Do you have peace of mind?" ), 2 ( "Do you feel satisfied with your life when you reflect on it?" ), 3 ( "Do you have someone that you spend time talking with?" ), and 4 ( "Are you satisfied with the home care service system?" ) were 52.3%, 52.3%, 79.5%, and 81.8%, respectively. The total scores for the patients and caregivers were significantly correlated (Spearman's ρ=0.364*). CONCLUSIONS: We created the first QOL scale for patients receiving home-based medical care and for caregivers. The findings of this study suggest that the QOL-HC can be used in clinical practice for the assessment of patients receiving professional home care.

Development and validation of a new quality of life scale for patients receiving home-based medical care: The Observational Study of Nagoya Elderly with Home Medical Care.

AIM: To develop and validate a scale that assesses quality of life in patients receiving home-based medical care. METHODS: A new quality of life scale was developed and evaluated in four phases: (i) item generation; (ii) first field study with a 14-item questionnaire; (iii) preliminary validation study, to reduce the number of items to four; and (iv) second field study comprising 40 patients, to evaluate the validity of the final version. Participants were requested to answer both the final version of the scale and the Short Form-8, to enable identification of any relationship between the two. RESULTS: Items were generated after discussions with doctors and care managers, and 14 items were selected for the draft version. In the preliminary validation study, 10 items were deleted, based on the results of statistical analysis of the data from the first field study. A psychometric analysis showed that the final four-item questionnaire had internal consistency (Cronbach's α = 0.7), and a significant association with the Short Form-8. CONCLUSIONS: We created the first quality of life scale for patients receiving home-based medical care. The scale's internal consistency was confirmed, as well as its external validity. This scale can be used independently of factors such as a patient's age, sex, level of independence in the presence of dementia or disability, swallowing function, hearing ability and communication ability, and can be used with ease in routine clinical practice.

[Comprehensive geriatric assessment for management of the elderly with diabetes mellitus].

In medical care for the elderly patients with diabetes mellitus, there are many cases that are not indicated for active treatment, because of their impairment of activity of daily living (ADL), instrumental ADL and cognitive function, and also the presence of some complications, such as cerebrovascular disorder. On the other hand, poor glycemic control is easy to induce dehydration, bacterial infection, and cognitive disorders in the elderly. Thus, it is necessary to maintain good glycemic control to preserve better ADL. However, compulsion of strict glycemic control might rather decrease QOL of the patient. To solve such a medical dilemma, the comprehensive geriatric assessment (CGA) is useful for the individual diabetic patient.
