Background:Although the aged population is increasing in developed countries, clinical evidence on super-elderly heart failure (HF) patients is scarce. This study determined the characteristics and outcomes of Japanese hospitalized super-elderly HF patients (aged ≥90 years) using a nationwide inpatient database.Methods and Results:A comprehensive analysis was performed of 447,818 HF patients in the Diagnosis Procedure Combination database who were hospitalized and discharged between January 2010 and March 2018. Among the study population, 243,028 patients (54.3%) were aged ≥80 years and 64,628 patients (14.4%) were aged ≥90 years. The percentage of elderly patients increased over time. Elderly patients were more likely to be female and had a higher New York Heart Association functional class at admission. Invasive and advanced procedures were rarely performed, whereas infectious complications were more common in patients with older age. Length of hospital stay and in-hospital mortality increased with age. Multivariable logistic regression analysis fitted with a generalized estimating equation showed higher in-hospital mortality in patients aged ≥80 and ≥90 years (odds ratios 1.99 and 3.23, respectively) compared with those aged <80 years.Conclusions:The number of hospitalized super-elderly HF patients has increased, and these patients are associated with worse clinical outcomes. The results of this study may be useful in establishing an optimal management strategy for super-elderly HF patients in the era of HF pandemic.

Background: The applicability of the Stages of Change model for cardiovascular disease-related behaviors, such as smoking, exercise, diet, and sleep quality, is unclear.Methods and Results: Using a large-scale epidemiological dataset, we found that baseline behavior change intention, as per the transtheoretical model, was associated with modifications of unhealthy lifestyles including cigarette smoking, physical inactivity, skipping breakfast, and poor sleep quality.Conclusions: Our results suggest that an individual’s motivation to change assessed by a general questionnaire may contribute to lifestyle modification and potentially prevent subsequent cardiovascular disease.

Aim: Obesity and metabolic syndrome (MetS) frequently coexist and are both important risk factors for cardiovascular disease. However, the pathophysiological role of obesity without MetS, also referred to as metabolically healthy obesity (MHO), remains unclear. In this study, we aim to clarify the effect of MHO on the development of carotid plaque using a community-based cohort.Methods: We examined 1,241 subjects who underwent health checkups at our institute. Obesity was defined by a body mass index of ≥ 25.0 kg/m2. Subjects were divided into three groups: non-obese, MHO, and metabolically unhealthy obesity (MUO).Results: The prevalence of carotid plaque, defined as intima-media thickness (IMT) ≥ 1.1 mm, was higher in subjects with MUO and MHO than in non-obese subjects. Multivariable analysis demonstrated that MHO (odds ratio 1.6, p=0.012) and MUO (odds ratio 1.9, p=0.003) as well as age of ≥ 65 years, male sex, hypertension, and diabetes mellitus were independently associated with carotid plaque formation. A similar trend was observed in each subgroup according to age and sex.Conclusions: MHO increased the prevalence of carotid plaque when compared with non-obese subjects, suggesting the potential significance of MHO in the development of subsequent cardiovascular diseases.

In this study, we investigated the taxonomic diversity of actinomycetes isolated from swine manure compost that had undergone self-heating. Pretreatment with sodium dodecyl sulfate and subsequent cultivation of the compost sample on humic acid-vitamin agar at 30 and 50°C resulted in the selective isolation of 125 actinomycete strains. These isolates were classified using a combination of morphological characterization and 16S rDNA sequence analysis, with sequence similarities of ≥97% and ≥99% used to identify isolates at genus and species level, respectively. The isolated actinomycete assemblage consisted of a diverse array of species, with the 125 isolates falling into 10 families, 15 genera, and 22 species. The most dominant thermophilic actinomycetes were Saccharomonospora (Sam.) viridis and Thermobifida fusca, followed by Actinomadura spp. Other species that were frequently isolated at 30°C included Glycomyces spp., Nocardiopsis (Nop.) alba, Nop. composta, Rhodococcus rhodochrous, and Sam. azurea.
