Our findings suggest that brachial-ankle pulse wave velocity is a significant predictive factor for cardiovascular disease in the general Japanese population and that information on brachial-ankle pulse wave velocity substantially improves cardiovascular risk assessment beyond that achieved by a model based on potential risk factors in general practice.
Noninvasive cSBP calculated with rSBP2 accorded well with aSBP measured by the invasive method. Vasodilator medication and four of five diseases did not affect this relation.
Aim: Peripheral artery disease (PAD), defined as a decreased ankle brachial index (ABI), is a risk factor for cardiovascular disease; however, few studies have assessed the relationship between a low ABI and cardiovascular risks in Asian populations. We herein examined the relationship between the ABI and the development of cardiovascular disease in a Japanese community. Methods: A total of 2,954 community-dwelling Japanese individuals without prior cardiovascular disease ≥ 40 years of age were followed up for an average of 7.1 years. The subjects' ABIs were categorized into the three groups: low (≤ 0.90), borderline (0.91-0.99) and normal (1.00-1.40). We estimated the relationship between the ABI and cardiovascular risk using a Cox proportional hazards model.
This review describes a new enzymatic method for in vitro glycogen synthesis and its structure and properties. In this method, short-chain amylose is used as the substrate for branching enzymes (BE, EC 2.4.1.18). Although a kidney bean BE and Bacillus cereus BE could not synthesize high-molecular weight glucan, BEs from 6 other bacterial sources produced enzymatically synthesized glycogen (ESG). The BE from Aquifex aeolicus was the most suitable for the production of glycogen with a weight-average molecular weight (Mw) of 3,000-30,000 k. The molecular weight of the ESG is controllable by changing the concentration of the substrate amylose. Furthermore, the addition of amylomaltase (AM, EC 2.4.1.25) significantly enhanced the efficiency of this process, and the yield of ESG reached approximately 65%. Typical preparations of ESG obtained by this method were subjected to structural analyses. The average chain length, interior chain length, and exterior chain length of the ESGs were 8.2-11.6, 2.0-3.3, and 4.2-7.6, respectively. Transmission electron microscopy and intrinsic viscosity measurement showed that the ESG molecules formed spherical particles. Unlike starch, the ESGs were barely degraded by pullulanase. Solutions of ESG were opalescent (milky-white and slightly bluish), and gave a reddishbrown color on the addition of iodine. These analyses revealed that ESG shares similar molecular shapes and solution properties with natural-source glycogen. Moreover, ESG had macrophage-stimulating activity and its activity depends on the molecular weight of ESG. We successfully achieved large scale production of ESG. ESG could lead to new industrial applications, such as in the food, chemical, and pharmaceutical fields.
We developed a new process for enzymatically synthesized glycogen (ESG), which is equivalent in physicochemical properties to natural-source glycogen (NSG) except its resistant property to degradation by α-amylase in vitro. In this study the metabolic fates of orally administered ESG in rats were investigated by a single oral administration test and a 2 week ingestion test. The glycemic index of ESG was 79. After the 2 week ingestion of ESG, the cecal content and production of short chain fatty acids were significantly increased, the pH value of cecal content was lowered, and the counts of Bifidobacterium and Lactobacillus in feces were significantly increased. Additionally, plasma levels of triacylglycerol and total cholesterol were significantly reduced by ESG. In contrast, NSG did not affect these parameters at all. The results collectively suggest that around 20% of orally administered ESG was transferred to the cecum in the form of polymer and assimilated into short chain fatty acids by microbiota and the polymer affected lipid metabolism.
This study’s objective was to explore the association between various factors and the increased caregiver burden of informal caregivers during the COVID-19 pandemic. On February, 2021, 700 informal caregivers completed an online survey. We assessed the change in caregiver burden during the COVID-19 pandemic. Among all caregiver participants, 287 (41.0%) complained of an increased caregiver burden due to the COVID-19 pandemic. The factors associated with increased caregiver burden were depressive symptoms in caregivers [odds ratio (OR), 2.20; 95% confidence interval (CI), 1.50–3.23], dementia (OR, 2.48; 95%CI, 1.07–5.73) and low Barthel Index scores (OR, 2.01; 95%CI, 1.39–2.90) in care receivers, care days (OR, 1.09; 95%CI, 1.01–1.17) and times (OR, 1.06; 95%CI, 1.01–1.10), and use of home care service (OR, 1.46; 95%CI, 1.01–2.10) and visiting care service (OR, 1.71; 95%CI, 1.20–2.45). These findings suggest we need to pay attention to the physical and mental health of both the care receivers and caregivers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
