Background And Aim: Werner syndrome (WS) is an autosomal recessive, adult-onset, progeroid syndrome caused by mutations. As refractory skin ulcers significantly affect the quality of life of patients with WS, this study identified ulcer risk factors and assessed prevention methods.
Methods: We analyzed the data of 51 patients with WS enrolled in the Japanese Werner Syndrome Registry between 2016 and 2022.

Aim: Addressing sarcopenia and frailty in aging populations is crucial for enhancing quality of life and reducing healthcare dependence. While the importance of energy, protein, and amino acid supplementation is known, the role of minerals needs further exploration. This systematic review evaluates the effectiveness of these minerals in managing sarcopenia and frailty.

Herein, we applied mechanical energy to a high molecular weight Dx to control its molecular weight and simultaneously generate mechanoradicals. The solid-state polymerization of methacrylate- or methacrylamide derivatives initiated with Dx mechanoradicals showed polymer conversion of >95%, yielding Dx-based graft copolymers with molecular weights of approximately 30,000 g mol.

Because dipeptidyl peptidase-4 (DPP4) and cysteinyl cathepsin K (CTSK) play important roles in human pathobiology, we investigated the role(s) of DPP4 in stress-related adipocyte differentiation, with a focus on the glucagon-like peptide-1 (GLP-1)/adiponectin-CTSK axis in vivo and in vitro. Plasma and inguinal adipose tissue from non-stress wild-type (DPP4), DPP4-knockout (DPP4) and CTSK-knockout (CTSK) mice, and stressed DPP4, DPP4, CTSK, and DPP4 mice underwent stress exposure plus GLP-1 receptor agonist exenatide loading for 2 weeks and then were analyzed for stress-related biological and/or morphological alterations.

Introduction: We examined the efficacy of a multidomain intervention in preventing cognitive decline among Japanese older adults with mild cognitive impairment (MCI).
Methods: Participants aged 65-85 years with MCI were randomized into intervention (management of vascular risk factors, exercise, nutritional counseling, and cognitive training) and control groups. The primary outcome was changes in the cognitive composite score over a period of 18 months.
Introduction: Patient empowerment, as part of patient-centered care, is important in the treatment of diabetes. However, this concept is still not well-understood by healthcare professionals, because it differs substantially from traditional approaches. We developed the "Diabetes Theater" workshop to promote a better understanding of patient empowerment.
View Article and Find Full Text PDFSarcopenia has a significant impact on falls, physical function, activities of daily living, and quality of life in older adults, and its prevention and treatment are becoming increasingly important as the global population ages. In addition to primary age-related sarcopenia, activity-related sarcopenia, disease-related sarcopenia, and nutrition-related sarcopenia have been proposed as secondary sarcopenia. Polypharmacy and potentially inappropriate medication based on multiple diseases cause health problems in older patients.

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).

Advance care planning (ACP) for people with dementia, as with other diseases, is a necessary process to realize medical treatment and care in the final stage of a person's life. On the other hand, dementia, a disease that is expected to make it difficult for people to make decisions on their own in the future, has a long course, and is characterized by uncertainty regarding the course of the disease, which may also be a limiting factor in the implementation of ACP for people with dementia. On the other hand, the uncertainties may also be a reason for implementing ACP.

Lysosomal cysteinyl cathepsins play an important role in human pathobiology. Given that cathepsin S (CTSS) is upregulated in the stressed vascular and adipose tissues, we investigated whether CTSS participates in chronic stress-induced skeletal muscle mass loss and dysfunction, with a special focus on muscle protein metabolic imbalance and apoptosis.

Here, we investigate the effect of myonectin on skeletal muscle atrophy in various male mouse models of muscle dysfunction.

Here, we examined whether CTSS participates in stress-related skeletal muscle mass loss and dysfunction, focusing on protein metabolic imbalance. Eight-week-old male wildtype (CTSS ) and CTSS-knockout (CTSS ) mice were randomly assigned to non-stress and variable-stress groups for 2 weeks, and then processed for morphological and biochemical studies.

Older patients are prone to multimorbidity or related polypharmacy, which may cause various adverse drug reactions (ADRs) and a high incidence of drug-related health problems. Although not often noted, ADRs include nutrition-related adverse reactions. Aging, multiple illnesses, mental and psychological problems, declining physical function, and environmental factors can lead to decreased food intake and increased metabolic stress in older people, resulting in energy imbalances that cause malnutrition.

Background: Exposure to chronic psychological stress is a risk factor for metabolic cardiovascular disease. Given the important role of lysosomal CTSS (cathepsin S) in human pathobiology, we examined the role of CTSS in stress-related thrombosis, focusing on inflammation, oxidative stress, and apoptosis.
Methods: Six-week-old wild-type mice (CTSS) and CTSS-deficient mice (CTSS) randomly assigned to nonstress and 2-week immobilization stress groups underwent iron chloride3 (FeCl)-induced carotid thrombosis surgery for morphological and biochemical studies.
This quick literature review aimed to organize information on the detailed components of total pain in older people with advanced dementia in a holistic manner. The authors analyzed qualitative data from relevant clinical guidelines or textbooks, focusing on certain types of pain and distress in older people with advanced dementia, followed by an expert panel review by research team members. In the search, the authors defined a person with advanced dementia as having a functional assessment staging tool scale score greater than or equal to six.

Older adults have physical and metabolic characteristics, and there are many differences in nutritional outcomes from middle-aged adults. In addition, there are many factors that cause malnutrition peculiar to the older adults, which are not seen in middle-aged adults, and it is easy for them to lose weight and become malnourished. Therefore, nutritional management needs to take into account the age of each subject.

Background: Young bone marrow transplantation (YBMT) has been shown to stimulate vascular regeneration in pathological conditions, including ageing. Here, we investigated the benefits and mechanisms of the preventive effects of YBMT on loss of muscle mass and function in a senescence-associated mouse prone 10 (SAMP10) model, with a special focus on the role of growth differentiation factor 11 (GDF-11).
Methods: Nine-week-old male SAMP10 mice were randomly assigned to a non-YBMT group (n = 6) and a YBMT group (n = 7) that received the bone marrow of 8-week-old C57BL/6 mice.
Background: Loss of skeletal muscle mass is associated with numerous factors such as metabolic diseases, lack of independence, and mortality in older adults. Therefore, developing simple, safe, and reliable tools for assessing skeletal muscle mass is needed. Some studies recently reported that the risks of the incidence of geriatric conditions could be estimated by analyzing older adults' gait; however, no studies have assessed the association between gait parameters and skeletal muscle loss in older adults.
