Prolonged delirium during hospitalization is associated with worse long-term and short-term outcomes in patients with acute heart failure.

BACKGROUND: The association between prolonged delirium during hospitalization and long-term prognosis in patients with acute heart failure (AHF) admitted to the cardiac intensive care unit (CICU) has not been fully elucidated. METHODS: We conducted a prospective registry study of patients with AHF admitted to the CICU at 2 hospitals from 2013 to 2021. We divided study patients into 3 groups according to the presence or absence of delirium and prolonged delirium as follows: no delirium, resolved delirium, or prolonged delirium. Main outcomes were in-hospital mortality and 3-year mortality after discharge. RESULTS: A total of 1555 patients with AHF (median age, 80 years) were included in the analysis. Of these, 406 patients (26.1%) developed delirium. We divided patients with delirium into 2 groups: the resolved delirium group (n = 201) or the prolonged delirium group (n = 205). Multivariate Cox proportional hazards models for long-term prognosis demonstrated that the prolonged delirium group had a higher incidence of all-cause death (hazard ratio [HR], 1.52; 95% CI, 1.08 to 2.14) and non-cardiovascular death (HR, 1.84; 95% CI, 1.21 to 2.78) than the resolved delirium group. Regarding in-hospital outcomes, multivariate logistic regression modeling showed that prolonged delirium is associated with all-cause death (odds ratio [OR], 9.55; 95% confidential interval [CI], 2.99 to 30.53) and cardiovascular death (OR, 13.02; 95% CI, 2.86 to 59.27) compared with resolved delirium. CONCLUSIONS: Prolonged delirium is associated with worse long-term and short-term outcomes than resolved delirium in patients with AHF.

Blood biomarker profiles and exceptional longevity: comparison of centenarians and non-centenarians in a 35-year follow-up of the Swedish AMORIS cohort.

Comparing biomarker profiles measured at similar ages, but earlier in life, among exceptionally long-lived individuals and their shorter-lived peers can improve our understanding of aging processes. This study aimed to (i) describe and compare biomarker profiles at similar ages between 64 and 99 among individuals eventually becoming centenarians and their shorter-lived peers, (ii) investigate the association between specific biomarker values and the chance of reaching age 100, and (iii) examine to what extent centenarians have homogenous biomarker profiles earlier in life. Participants in the population-based AMORIS cohort with information on blood-based biomarkers measured during 1985-1996 were followed in Swedish register data for up to 35 years. We examined biomarkers of metabolism, inflammation, liver, renal, anemia, and nutritional status using descriptive statistics, logistic regression, and cluster analysis. In total, 1224 participants (84.6% females) lived to their 100th birthday. Higher levels of total cholesterol and iron and lower levels of glucose, creatinine, uric acid, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, lactate dehydrogenase, and total iron-binding capacity were associated with reaching 100 years. Centenarians overall displayed rather homogenous biomarker profiles. Already from age 65 and onwards, centenarians displayed more favorable biomarker values in commonly available biomarkers than individuals dying before age 100. The differences in biomarker values between centenarians and non-centenarians more than one decade prior death suggest that genetic and/or possibly modifiable lifestyle factors reflected in these biomarker levels may play an important role for exceptional longevity.

Centenarians: who are they? A description of the total Swedish centenarian population in terms of living arrangements, health, and care utilization.

BACKGROUND: The global centenarian population has doubled each decade and is expected to continue growing. However, information regarding how they live, their health status, and care needs is limited. AIMS: This study aims to describe the total Swedish centenarian population in terms of health status, living arrangements, and socio-demographic characteristics. METHODS: This nationwide register-based study included all Swedish people reaching age 100 between 2013 and 2018. We analyzed their socio-demographic characteristics, living arrangements, number of prescribed drugs, and health status. Moreover, their care transitions from age 100 and two years forward were described. RESULTS: Of 5,882 centenarians (80.7% women), only 15.0% lived at home without formal care and 24.5% cohabited on their 100th birthday. Men (22.7%) were more likely than women (13.2%) to live at home without care. Approximately half of the centenarians lived in care homes, with fewer men (41.0%) than women (54.0%). Around 66.6% had a child living within the 50 km range. Most (76.5%) had an income below the median for Swedish older adults. Almost none were free from drugs, and polypharmacy was common (65.3%). Over half had at least one morbidity. Two years later, only 4.3% lived at home without care, and 63.9% died. CONCLUSION: Sweden's centenarian population is highly dependent on home care and care homes. Among the ones still living at home, the vast majority live alone and have low incomes. Strategies to manage health and social care demands of this growing population group in the coming decade are important.

Cognitive transitions based on functional status in older adults with heart failure: a population-based study.

AIMS: Cognitive impairment and functional status are both important determinants of poor outcomes in heart failure (HF). However, little is known about how functional status impacts the changes in cognitive status during the disease course. This study aimed to describe the cognitive transitions in patients with HF and assess the relationship of these transitions to functional status, which was assessed by the dependency of activities of daily living (ADL). METHODS AND RESULTS: This retrospective cohort study included 1764 patients with an International Classification of Diseases-10 code of HF (≥65 years, mean age 82.3 ± 7.9 years, 39% male) from a long-term care and medical insurance database from Nobeoka city, a rural city of south-western Japan. Cognitive status at baseline and 6, 12, 18, and 24 month time points was collected, and participants were stratified based on ADL status at baseline. Generalized estimating equations and multi-state modelling were used to examine associations between ADL dependency and cognitive changes/mortality. Transition probabilities were estimated using multi-state modelling. At baseline, there were 1279 (73%) and 485 (27%) patients with independent and dependent ADL, respectively. In overall patients, 1656 (93.9%) patients had normal/mild cognitive status and 108 (6%) patients had a moderate/severe cognitive status at baseline. The majority [104 (96%) patients] of patients with moderate/severe cognitive status at baseline had dependent ADL. In patients with moderate/severe cognitive status, the number of patients with dependent ADL always outnumbered that of the independent ADL throughout the follow-up. Multi-state modelling estimated that patients with dependent ADL and normal/mild cognitive status at baseline had 47% probability of maintaining the same cognitive status at 24 months, while the probability of maintaining the same cognitive status was 86% for those with independent ADL. Patients with normal/mild cognitive status in the dependent ADL group at baseline had a higher risk of experiencing a transition to moderate/severe cognitive status at any time point during 24 months compared with those with independent ADL [hazard ratio 5.24 (95% confidence interval 3.47-7.90)]. CONCLUSIONS: In older patients with HF, the prevalence of cognitive impairment was always higher for those with reduced functional status. Despite having a normal/mild cognitive status at baseline, patients with dependent ADL are at high risk of experiencing cognitive decline over 24 months with substantially less chance of maintaining their cognitive status. ADL dependency was an important risk factor of cognitive decline in patients with HF.

Studies of Health Insurance Claims Data in Japan: A Scoping Review.

Background: Health insurance claims data are used in various research fields; however, an overview on how they are used in healthcare research is scarce in Japan. Therefore, we conducted a scoping review to systematically map the relevant studies using Japanese claims data. Methods: MEDLINE, EMBASE, and Ichushi-Web were searched up to April 2021 for studies using Japanese healthcare claims data. We abstracted the data on study characteristics and summarized target diseases and research themes by the types of claims database. Moreover, we described the results of studies that aimed to compare health insurance claims data with other data sources narratively. Results: A total of 1,493 studies were included. Overall, the most common disease classifications were "Diseases of the circulatory system" (18.8%, n = 281), "Endocrine, nutritional, and metabolic diseases" (11.5%, n = 171; mostly diabetes), and "Neoplasms" (10.9%, n = 162), and the most common research themes were "medical treatment status" (30.0%, n = 448), "intervention effect" (29.9%, n = 447), and "clinical epidemiology, course of diseases" (27.9%, n = 417). Frequent diseases and themes varied by type of claims databases. A total of 19 studies aimed to assess the validity of the claims-based definition, and 21 aimed to compare the results of claims data with other data sources. Most studies that assessed the validity of claims data compared to medical records were hospital-based, with a small number of institutions. Conclusions: Claims data are used in various research areas and will increasingly provide important evidence for healthcare policy in Japan. It is important to use previous claims database studies and share information on methodology among researchers, including validation studies, while informing policymakers about the applicability of claims data for healthcare planning and management.

Dynamic changes of the direction and angle of radiographic ocular lateral deviation in patients with lateropulsion after stroke onset.

OBJECTIVE: To examine if radiographic ocular lateral deviation (rOLD) could be provoked in stroke patients with mild-to-moderate lateropulsion according to vertical perception. METHODS: In this single-center, retrospective study, acute stroke patients with mild-to-moderate lateropulsion assessed by the Scale for Contraversive Pushing were enrolled. Computed tomography or magnetic resonance imaging was performed on all patients on admission and then according to their conditions. The direction and angle of rOLD were compared among three groups according to the responsible lesion: lateral medullary (LM), pontine (P), and hemispheric (H). RESULTS: Sixty-six patients (male, 47; average age, 67 years) were enrolled and divided into the LM (n = 37), P (n = 8), and H (n = 21) groups. All patients had body tilt. Patients in the LM group showed body tilt to the ipsilesional side during hospitalization, while those in the P and H groups tilted to the contralesional side. All patients had rOLD at the final assessment at an average of 13 days after onset; patients in the P and H groups showed contralateral rOLD, while those in the LM group showed ipsilateral rOLD if they did not have cerebellar or pontine lesions. Significant decreases in the angle and changes in direction of rOLD according to lesion site were observed during hospitalization. CONCLUSION: Serial changes in rOLD findings after stroke onset are different according to the responsible lesion. The direction of rOLD in most patients is in accordance with vertical perception after the acute stage of stroke.

In-hospital predictors for primary prevention of sudden death after acute myocardial infarction with cardiac dysfunction.

BACKGROUND: Current guidelines recommend prophylactic defibrillator implantation in patients with acute myocardial infarction (AMI) and left ventricular ejection fraction (LVEF) ≤40 % or LVEF ≤35 % plus heart failure symptoms or inducible ventricular tachyarrhythmias during an electrophysiology study at 40 days after AMI or 90 days after revascularization. In-hospital predictors of sudden cardiac death (SCD) after AMI during the index hospitalization remain unsettled. We sought to examine in-hospital predictors of SCD in patients with AMI and LVEF ≤40 % evaluated during the index hospitalization. METHODS: We retrospectively evaluated 441 consecutive patients with AMI and LVEF ≤40 % admitted to our hospital between 2001 and 2014 (77 % male gender; median age: 70 years; median hospitalization length: 23 days). The primary endpoint was a composite of SCD or aborted SCD at ≥30 days after AMI onset (composite arrhythmic event). LVEF and QRS duration (QRSd) on electrocardiography were measured at a median of 12 days and 18 days, respectively. RESULTS: During a median follow-up of 7.6 years, the incidence of composite arrhythmic events was 7.3 % (32 of 441 patients). In multivariable analysis, QRSd ≥100 msec (beta-coefficient = 1.54, p = 0.003), LVEF ≤23 % (beta-coefficient = 1.14, p = 0.007), and onset-reperfusion time > 5.5 h (beta-coefficient = 1.16, p = 0.035) were independent predictors of composite arrhythmic events. The combination of these 3 factors was associated with the highest rate of composite arrhythmic events compared with 0-2 factors (p < 0.001). CONCLUSIONS: The combination of QRSd ≥100 msec, LVEF ≤23 %, and onset-reperfusion time > 5.5 h during the index hospitalization provides precise risk stratification for SCD in patients early after AMI.

Prognostic Predictors of Tricuspid Regurgitation Worsening after Mitral Regurgitation Surgery with Mild Tricuspid Regurgitation.

We aimed to investigate the prevalence and predictors of postoperative tricuspid regurgitation (TR) worsening in patients with mitral regurgitation (MR) and concomitant ≤mild TR. A total of 620 patients underwent surgery for MR from 2013 to 2017. Of these, 260 had ≤mild preoperative TR and no concomitant tricuspid valve surgery and were enrolled in this single-center retrospective study. The primary endpoint was postoperative worsening of ≥moderate TR. The primary endpoint occurred in 28 of 260 patients (11%) during the follow-up period [median: 4.1 years (interquartile range: 2.9-6.1 years)]. In the multivariable analysis, age, female sex, and left atrial volume index (LAVI) were significant predictors of the primary outcome during intermediate-term follow-up (age: hazard ratio [HR] 1.05 per 1-year increment, 95% confidence interval [CI] 1.02-1.10, P = 0.003; female sex: HR 3.53, 95% CI 1.61-7.72, P = 0.002; LAVI: HR 1.17 per 10-mL/m2 increment, 95% CI 1.07-1.26, P < 0.001). The optimal LAVI cut-off value for predicting postoperative TR worsening was 79 mL/m2 (area under the curve: 0.69). A high LAVI (>79 mL/m²) was significantly associated with a low rate of freedom from postoperative TR worsening compared with a low LAVI (≤79 mL/m²) (82.6% vs 93.9% at 5 years, respectively; log-rank P = 0.008). In patients with ≤mild preoperative TR and no concomitant tricuspid surgery, the rate of postoperative TR worsening was 11% during intermediate-term follow-up. LA enlargement in patients with MR and ≤mild preoperative TR was significantly associated with postoperative TR worsening.

Claimed-based frailty index in Japanese older adults: a cohort study using LIFE Study.

BACKGROUNDS: We aimed to assess whether the U.S. developed claimed-based frailty index (CFI) can be implemented in Japanese older adults using claim data. METHODS: We used the monthly claims data and certification of long-term care (LTC) insurance data of residents from 12 municipalities from April 2014 to March 2019. The 12 months from first recording was defined as the "baseline period," and the time thereafter as "follow-up period". Participants aged ≥65 years and those with no certified LTC insurance or who died at baseline were included. New certification of LTC insurance and all-cause mortality during the follow-up period were defined as outcome events. CFI categorization consisted of three steps including: 1) using 12 months deficit-accumulation approach that assigned different weights to each of the 52 items; 2) the accumulated score to derive the CFI; and 3) categorizing the CFI as "robust" (<0.15), "prefrail" (0.15-0.24), and "frail" (≥0.25). Kaplan-Meier survival curves and Cox proportional hazard models were used to determine the association between CFI and outcomes. Hazard ratios (HR) and 95% confidence intervals (95%CI) were calculated. RESULTS: The participants were 519,941 in total. After adjusting for covariates, the severe CFI category had a high risk of certification of LTC insurance (prefrail, HR: 1.33, 95%CI:1.27-1.39; frail, HR: 1.60, 95%CI: 1.53-1.68) and all-cause mortality (prefrail, HR: 1.44, 95%CI: 1.29-1.60; frail, HR: 1.84, 95%CI: 1.66-2.05). CONCLUSIONS: This study suggests that CFI can be implemented in Japanese claims data by predicting the certification of LTC insurance and mortality.

Real-world comparison of in-hospital complications after catheter ablation for atrial fibrillation between non-antivitamin K anticoagulants and warfarin: A propensity-matched analysis using nation-wide database.

Background: Few large-scale, real-world studies have compared the efficacy and safety of non-antivitamin K anticoagulants (NOACs) with that of warfarin in catheter ablation (CA) for atrial fibrillation (AF). Methods: This retrospective, cross-sectional study used a nationwide administrative claims database, to compare complication-incidence rates following CA for AF between NOAC-treated patients and warfarin-treated matched cohorts in the real-world. Among the 32,797,540 records between June 2011 and August 2020 from 426 hospitals, 41,347 patients (38,065 on NOACs and 3,282 on Warfarin) were considered eligible. After performing propensity matching, 6,564 patients (3,282 per group) were analyzed. Results: The overall complication incidence was significantly lower in the NOACs group than in the warfarin group (2.3 % vs. 4.0 %; P < 0.001, odds ratio [OR]: 0.55, 95 % confidence interval [CI]: 0.41-0.74). Although no significant differences in the incidence of cardiac tamponade (1.0 % vs. 1.1 %; P = 0.90, OR: 0.97, 95 % CI: 0.60-1.56) and major bleeding (0.6 % vs. 0.7 %; P = 0.54, OR: 0.83, 95 % CI: 0.44-1.52) were noted, blood transfusion requirements (0.6 % vs. 1.2 %; P = 0.02, OR: 0.52, 95 % CI: 0.30-0.88) and vascular complications (0.2 % vs. 0.5 %; P = 0.02, OR: 0.33, 95 % CI: 0.12-0.79) were significantly lower in the NOACs group than in the warfarin group. Furthermore, the thromboembolic event incidence was significantly lower in the NOACs group than in the warfarin group (0.5 % vs. 1.2 %; P < 0.001, OR: 0.36, 95 % CI: 0.19-0.64). Conclusions: NOACs should be considered as a first-line therapy for periprocedural anticoagulation in patients undergoing CA for AF.

The Japan-Multimodal Intervention Trial for Prevention of Dementia PRIME Tamba (J-MINT PRIME Tamba): Study protocol of a randomised controlled multi-domain intervention trial.

The Japan-Multimodal Intervention Trial for Prevention of Dementia PRIME Tamba (J-MINT PRIME Tamba) is a randomised controlled trial to prevent cognitive decline in community-dwelling cognitively ordinary older people at risk of dementia. Participants are aged 65-85 years living in a rural area in Japan, aware of very mild decline in cognitive function or abilities of activities of daily living, have at least one vascular risk (e.g. hypertension or diabetes), and have a Mini-Mental State Examination score of 24 or higher. Approximately 200 participants are randomly divided into two groups, with the intervention group receiving a multi-modal intervention, including lifestyle-related disease management, physical exercise, cognitive training, and nutritional counselling, over 18 months. The primary outcome is change in the composite score of seven neuropsychological tests, including the Free and Cued Selective Reminding Test, Logical Memory I and II subsets of the Wechsler Memory Scale-Revised, and Digit Symbol Substitution Test of the Wechsler Adult Intelligence Scale. In addition, changes in a wide range of other parameters such as physical function, blood test results, sleep, and frailty are also analysed as secondary outcomes. We believe that this study's results will contribute significantly to the development of dementia prevention measures in Japan. Clinical trial registration number: UMIN000041938.

Aetiology of chronic heart failure in patients from a super-aged society: the KUNIUMI registry chronic cohort.

AIMS: With the rapidly increasing ageing population, heart failure is an urgent challenge, particularly in developed countries. The study aimed to investigate the main aetiologies of chronic heart failure in a super-aged society. METHODS AND RESULTS: The KUNIUMI registry chronic cohort is a community-based, prospective, observational study of chronic heart failure in Awaji Island, Japan. Inhabitants of this island aged ≥65 years accounted for 36.3% of the population. In the present study, data from patients with symptomatic heart failure were extracted from the registry. A total of 1646 patients were enrolled from March 2019 to March 2021, accounting for ~1.3% of the inhabitants of Awaji Island. We analysed 852 patients with symptomatic heart failure. The mean age was high (78.7 ± 11.1 years), with 357 patients (41.9%) being female. The proportion of women increased significantly with advancing age and constituted more than half of the patients aged 85 years and older (P < 0.01). The prevalence of atrial fibrillation, and in particular long-standing persistent atrial fibrillation, increased at 70 years of age (P < 0.01). The proportion of patients with heart failure with preserved ejection fraction increased to ~60% when age was over 75 years. Although ischaemic heart disease accounted for 35.0% of chronic heart failure aetiologies, valvular heart disease was the most common cause of chronic heart failure (49.8%). The major types of valvular heart disease were mitral regurgitation and tricuspid regurgitation (27.2% and 21.7%, respectively), both of which increased significantly with age (P < 0.01). The incidence of aortic valve stenosis increased markedly over the age of 85 years (P < 0.01). Atrial functional mitral regurgitation increased with age and was the major cause of mitral regurgitation in patients aged >75 years. Patients with atrial functional mitral regurgitation had a higher prevalence of atrial fibrillation (especially long-standing persistent atrial fibrillation) and a larger left atrial volume index when compared with patients with other types of mitral regurgitation (P < 0.001, respectively). CONCLUSIONS: The KUNIUMI registry chronic cohort showed a change in heart failure aetiology to valvular heart disease in a super-aged society. Effective and comprehensive countermeasures are required to prepare for the rapid rise in heart failure incidence in a super-aged society.

Frequency of working at home, body mass index, and productivity in Japanese office workers: A cohort study.

BACKGROUND: Since the start of the COVID-19 pandemic, the number of people working at home has grown significantly. OBJECTIVE: This cohort study aimed to investigate whether the frequency of working at home was associated with changes in body mass index (BMI) and productivity from 2018 to 2020. METHOD: Frequency of working at home was self-reported. Participants were classified into three groups based on mean frequency of working at home per week (no working at home: ≦ 0.5 days, low frequency: 0.5 to 2.5 days, and high frequency: >2.5 days). Productivity was measured using a numerical rating scale, and BMI was calculated using height and weight. Changes in BMI and productivity were calculated by subtracting 2018 data from 2020 data. Linear regression analysis was performed by considering BMI and productivity change as outcomes and frequency of working at home as explanatory variable. RESULTS: BMI change in the high frequency group was significantly smaller than in the group that did not work at home (crude; coefficient: -0.27; 95% CI: -0.55--0.01, adjusted; coefficient: -0.30; 95% CI: -0.60--0.01). Frequency of working at home was not associated with productivity change. CONCLUSION: Working at home may be a solution for preventing BMI from increasing significantly.

Joint effect of cognitive decline and walking ability on incidence of wandering behavior in older adults with dementia: A cohort study.

OBJECTIVES: Wandering behavior is one of the most troublesome behavioral disturbances in dementia. Inconsistent associations between physical function and wandering behavior were reported, and the effect of cognitive decline may be different according to walking ability. The purposes of this study are to investigate whether high walking ability is a risk factor for wandering behavior and to investigate the interaction of walking ability and cognitive function with wandering behavior in older adults with dementia. METHODS: This retrospective cohort study included 3979 elderly adults with dementia. The association of cognitive function and walking ability with incidence of wandering behavior during a 5-year follow-up period were examined using a generalized linear model, and relative excess risk due to interaction (RERI) was calculated. RESULTS: Severe cognitive decline and high walking ability were associated with a higher risk for wandering behavior. Additionally, some joint effects of cognitive decline and walking ability decline were higher than the sum of its individual effects (RERI [95% confidence interval], severe cognitive decline × 'walk with help': 1.58 [0.35, 2.81]; severe cognitive decline × 'independent': 3.09 [1.05, 5.14]). CONCLUSIONS: Effects of cognitive decline and walking ability on incidence of wandering behavior were observed, and the effects varied depending on their combination.

Association between Abnormal Gait Patterns and an Elevated Degree of Pain after Daily Walking: A Preliminary Study.

This study aimed to investigate whether abnormal gait patterns are associated with experiencing an elevated degree of pain after daily walking. In this preliminary, cross-sectional study, 223 community-dwelling older adults were assessed for pain experienced after daily walking using a simple question that involved asking the subject about their past experiences of an elevated degree of pain after walking for 400 m or more. Gait patterns were assessed using the Comprehensive Gait Assessment using InerTial Sensor score (C-GAITS score), derived from the data measured by Inertial sensors attached to the lower trunk and heel when subjects walked along a 15 m walkway at a self-selected preferred speed. The score was the sum of 10 gait parameter scores. The lower scores indicated more and worse abnormal gait patterns. In total, 24 older adults (10.8%) reported that they experienced pain after daily walking. According to the multiple logistic regression analyses, older adults with a lower total C-GAITS score had a significantly greater probability of having past experiences of pain after walking (odds ratio = 1.11, 95% confidence interval = 1.03-1.20). The findings of this study suggest that more and worse abnormal gait patterns among older adults in a clinical walking test are associated with an elevated degree of pain after daily walking.

Indirect effects of social activity on appetite via depressive symptoms in community-dwelling older adults: A cross-sectional study.

Depressive symptoms have a strong effect on appetite decline in older adults. There is also an association between social activity and decreased depressive symptoms, but the mechanism between appetite and social activity with respect to depressive symptoms is unclear. This cross-sectional study examined the direct and indirect effects of social activity on appetite, via depressive symptoms. A total of 259 community-dwelling older adults (mean age 75.1 ± 5.3 years; 55% female) completed the Council on Nutrition Appetite Questionnaire (CNAQ) and the 15-item version of the Geriatric Depression Scale (GDS). We used a cutoff score of 6 on the GDS-15 to determine whether participants displayed depressive symptoms. Social activity was assessed based on the number of activities participated in at least 1-3 times per month. The types of social activity consisted of local community, hobby, sports, citizen, industry, religion, volunteer, and others. Other assessed factors included age, sex, education, financial status, living situation, and comorbidities. To examine the relationships among social activity, depressive symptoms, and appetite, structural equation modeling (SEM) was used, adjusting for variables associated with depressive symptoms or appetite in multivariate analyses. SEM revealed that participation in more types of social activity had a significant indirect effect on higher appetite score via less having depressive symptoms (ß = 0.04, p = 0.018). Our findings suggest that active participation in social activities may have a positive effect on good appetite via not having depressive symptoms among older adults. Further longitudinal or intervention studies are needed to confirm our findings.

Thyroid Storm Patients With Elevated Brain Natriuretic Peptide Levels and Associated Left Ventricular Dilatation May Require Percutaneous Mechanical Support.

OBJECTIVES: To determine the characteristics of thyroid storm patients with acute decompensated heart failure who should be candidates for temporary percutaneous mechanical circulatory support in addition to beta-blocker treatment to prevent cardiogenic shock. DESIGN: A single-center, retrospective review of treatment details and data collected from electronic medical records. SETTING: Thyrotoxicosis complicated with acute decompensated heart failure. PATIENTS: Eight consecutive patients who were admitted to our hospital for acute decompensated heart failure with thyroid storm between December 2011 and August 2020 were retrospectively reviewed. Of the eight patients, four were treated with percutaneous mechanical circulatory support. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Compared with thyroid storm patients who did not require percutaneous mechanical circulatory support, those who did had a significantly higher initial plasma brain natriuretic peptide level (1,231 [911-3,387] vs 447 pg/mL [243-653 pg/mL], respectively; p = 0.015), as well as a significantly larger left ventricular end-diastolic diameter (56 [54-63] vs 48 mm [38-48 mm], respectively; p = 0.029) and end-systolic diameter (50 [49-58] vs 28 mm [28-30 mm], respectively; p = 0.029) on echocardiogram. In terms of thyroid storm severity, the Burch-Wartofsky score was higher in patients with percutaneous mechanical circulatory support than in those without, although the difference was not significant. All patients survived this index admission. CONCLUSIONS: In thyroid storm patients, the presence of a high brain natriuretic peptide level, "left ventricular dilatation," or both may necessitate hemodynamic assessment to determine the indication of percutaneous mechanical circulatory support before beta-blocker administration.

Effect of a Combined Exercise and Cognitive Activity Intervention on Cognitive Function in Community-dwelling Older Adults: A Pilot Randomized Controlled Trial.

OBJECTIVE: The purpose of this study is to investigate the effect of an intervention combining exercise and cognitive activity on cognitive function in healthy older adults. METHODS: This pilot randomized controlled trial recruited 33 eligible, healthy communitydwelling older adults (mean age, 77.1 years old; women, 51.5%), who were divided into intervention and waitlist control groups. The intervention group was engaged weekly in a group activity comprising exercise and discussions of homework, which included reading aloud, simple arithmetic, and simple activities, like spotting differences, for cognitive stimulation. They were also required to complete cognitive activity homework twice a week. The waitlist control group received no intervention. The main outcomes were cognitive function assessed using the Mini-Mental State Examination, delayed recall score on the Logical Memory IIA of the Wechsler Memory Scale Revised, Trail Making Test, and digit symbol substitution test. RESULTS: According to the results, Mini-Mental State Examination scores were maintained in the intervention group but declined in the control group [Mean change in outcomes in control group (95% confidence interval): -1.68 (-2.89 to -0.48)]. Additional mean change in outcomes in intervention group were found [1.68 (0.02 to 3.35)]. CONCLUSIONS: Interventions combining exercise and cognitive activity can be helpful for preserving cognitive function in healthy older adults.
