This study aimed to evaluate the effects of functional foods containing powder on gut health and clinical indicators in middle-aged and older adults. Participants were randomly assigned to either the intervention group (n = 24) or control group (n = 26), and assessments including anthropometric measurements, blood analyses, and dietary intake surveys were conducted. The intervention group consumed functional foods containing powder twice daily for 8 weeks.

Objectives: This study investigates the changing perceptions of Korean care workers regarding a robotic bed designed to assist with repositioning and prevent pressure ulcers. With the primary aim of assessing the technology acceptance among care workers using the robotic bed to solve the problem of a shortage of care workers in Korea, we sought to examine the possibility of applying care robots in the field.
Methods: A total of 20 long-term care workers participated in the experiment, and their attitudes were measured before and after using the robot.
This study aimed to determine whether patients with type 2 diabetes can benefit from a meal plan designed based on diabetes management guidelines to improve blood glucose levels. Participants were divided into intervention and control groups. The intervention group consumed a diabetic diet for 2 weeks, while the control group consumed their normal diet.

Participants were assigned to either the collagen group (15 g/day of collagen peptide) or the placebo group (placebo drink). Body composition was measured by bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DEXA).

Compared to the driving group, the driving cessation group in this study was found to be a high-risk population in terms of their life satisfaction. This study evaluated data from 315 older adults, aged 55 or older, using the 2018 Korean Older Adults Driving and Mobility Service Trend Survey. These data were collected from 17 representative cities and provinces in South Korea.

For health maintenance and improvement, preventive healthcare measures including safe food selection and nutritional supply are needed. This study aimed to evaluate the effect of senior-friendly diet on nutrition and health status improvement in older adults receiving community care.

They are at a higher risk of experiencing violence-including physical, emotional, and sexual-from patients or their families, possibly leading to high turnover intention. This study aims to verify how having experienced client violence affect turnover intention of long-term care workers and to suggest implications to prevent frequent turnover in long-term care field.
View Article and Find Full Text PDFLong-term Care Insurance (LTCI) was created for the elderly, to provide various types of medical and care services, along with the National Health Insurance (NHI). However, the elderly must choose one of these systems, which leads to some of them being unable to receive services and care/medical care based on their needs, because the LTCI only provides limited services, regardless of the needs of the elderly. In order to establish the best solution between the LTCI and NHI, I conducted a utilization effect analysis; using the difference in difference (DID) and difference in difference in difference (DDD) methods with National Health Insurance Services-senior (NHIS-senior) cohort data from 2008 to 2013.

Objectives: Drawing on the stress coping theory, this study examines whether negative attitudes toward aging and low levels of active coping are associated with greater depressive symptoms, and whether active coping attenuates the increased risk of depression caused by negative aging attitudes. We also investigate how these associations differ in middle-aged and older adults.

Health literacy is closely associated with poor health outcomes and mortality. However, only a handful of studies have examined the association between health literacy and frailty status. The current study used data from a nationwide sample of Korean adults aged 70-84 collected from 10 cities, each of which represents a different region of South Korea ( = 1521).

The IL-1 receptor-associated kinase 1 (IRAK1) gene on the X chromosome was recently suggested as strong autoimmune disease-susceptible loci, second to the major histocompatibility complex region. We investigated the frequency of IRAK1 single-nucleotide polymorphisms (SNPs) in children with AITD.

The use of the well-known powerful antioxidant ascorbate has recently become more widespread in human medicine. Intravenous administration of high-dose ascorbate has been demonstrated to exert anticancer effects. It has resulted in effective cell death in vitro and inhibition of tumour growth in vivo.

However, despite diverse research studies conducted on its biocompatibility, its uses are still limited. The main reason is the degree of deacetylation (DOD), which represents the proportion of deacetylated units in the polymer and is directly correlated with its biocompatibility property.

Macromolecular nanoparticles can extravasate and accumulate within tumor tissues via the passive targeting system, reflecting enhanced permeability and the retention effect. However, the unsatisfactory tumor therapeutic efficacy of the passive-targeting system, attributable to the retention of extravasated nanoparticles in the vicinity of tumor vessels, argues that a new system that facilitates intracellular delivery of nanoparticles within tumors is needed. Here, we developed hydrophobically modified glycol chitosan (HGC) nanoparticles conjugated with interleukin-4 receptor (IL-4R) binding peptides, termed I4R, and tested them in mice bearing IL-4R-positive tumors.

To design the pH-responsive polymeric micelles, hydrophilic methyl ether poly(ethylene glycol) (MPEG) and pH-responsive/biodegradable poly(beta-amino ester) (PAE) were copolymerized using a Michael-type step polymerization, resulting in an MEPG-PAE block copolymer. The amphiphilic MPEG-PAE block copolymer formed polymeric micelles with nano-sized diameter by self-assembly, which showed a sharp pH-dependant micellization/demicellization transition at the tumoral acidic pH value (pH 6.

The active tumor targeting and tumoral pH-responsive polymeric micelles were prepared by mixing AP peptide conjugated PEG-poly(d,l-lactic acid) block copolymer (AP-PEG-PLA) into the pH-responsive micelles of methyl ether poly(ethylene glycol) (MPEG)-poly(beta-amino ester) (PAE) block copolymer (MPEG-PAE). These mixed amphiphilic block copolymers were self-assembled to form stable AP peptide-conjugated and pH-responsive AP-PEG-PLA/MPEG-PAE micelles (AP-pH-PMs) with an average size of 150 nm.
