Objectives: The study aimed to develop a machine learning (ML) model to predict early postdischarge falls in older adults using data that are easy to collect in acute care hospitals. This may reduce the burden imposed by complex measures on patients and health care staff.

Design: This prospective multicenter study included patients admitted to and discharged from geriatric wards at 3 university hospitals and 1 national medical center in Japan between October 2019 and July 2023.

Background: Robot-assisted surgery is widely performed for renal cell carcinoma (RCC) with inferior vena cava (IVC) tumor thrombi. Although many chemotherapeutic options are available for the treatment of unresectable RCC, there are very few reports on robot-assisted radical nephrectomy (RARN) with inferior vena cava thrombectomy (IVCT) after presurgical treatment with immune checkpoint inhibitors and tyrosine kinase inhibitors. We believe that pre-surgical treatment can provide minimally invasive surgical benefits to high-risk patients during the perioperative period.

The development of successful therapeutics for dementias requires an understanding of their shared and distinct molecular features in the human brain. We performed single-nuclear RNA-seq and ATAC-seq in Alzheimer's disease (AD), frontotemporal dementia (FTD), and progressive supranuclear palsy (PSP), analyzing 41 participants and ∼1 million cells (RNA + ATAC) from three brain regions varying in vulnerability and pathological burden. We identify 32 shared, disease-associated cell types and 14 that are disease specific.

Acrylamide may affect sex hormone levels and the timing of sexual maturation. The present study cross-sectionally examined interrelationship between the urinary metabolite of acrylamide exposure, serum sex hormone levels, and pubertal status in 408 Japanese adolescents aged 13-14 years. Their caregivers completed a questionnaire concerning the health status of their children, including pubertal maturation, and the lifestyles of children and parents.

Background: Family caregivers of dementia patients face significant challenges, including managing their own emotional responses. Understanding factors influencing expressed emotion (EE) is crucial for effective support interventions. The aim of this study was to explore and describe changes in EE among family caregivers of dementia and its associated factors at different time points over 3 months.

Background: Low vaccination coverage among travelers poses a critical challenge to global health security. Indeed, public concerns regarding vaccines can lead to vaccine reluctance and refusal, but evidence about the impacts of concerns regarding vaccines on the uptake of travel vaccinations remains sparse. We examined the associations between concerns about vaccines and vaccination behavior among travelers.

Patchy nanocubes are intriguing materials with simple shapes and space-filling and multidirectional bonding properties. Previous studies have revealed various mesoscopic structures such as colloidal crystals in the solid regime and rod-like or fractal-like aggregates in the liquid regime of the phase diagram. Recent studies have also shown that mesoscopic structural properties, such as an average cluster size M and orientational order, in amphiphilic nanocube suspensions are associated with macroscopic viscosity changes, mainly owing to differences in cluster shape among patch arrangements.

Article Synopsis
  • - The review aimed to identify how common sleep disturbances are in individuals with mild cognitive impairment (MCI), analyzing data from a wide range of databases, resulting in 52 studies being considered, with six excluded for quality concerns.
  • - Among the studies included, subjective sleep disturbances were reported in 35.8% of participants, while objective measurements showed a higher prevalence of 46.3% for sleep issues.
  • - The study found variations in sleep disturbance prevalence based on measurement methods, study designs, and geographical regions, highlighting the need for targeted intervention strategies to address these sleep problems in people with MCI.

Article Synopsis
  • The study aimed to identify fluid biomarkers in cerebrospinal fluid (CSF) for progressive supranuclear palsy (PSP) to aid in developing new therapies, utilizing advanced proteomic analysis methods.
  • Researchers analyzed a total of 136 participants across various groups, comparing individuals with PSP (Richardson syndrome) against healthy controls, using sophisticated platforms to assess the presence of specific proteins (SOMAmers) in CSF.
  • Findings revealed that many SOMAmers were differentially expressed in PSP patients, indicating potential biomarkers, with three significant biological pathways linked to disease progression identified, including synaptic functions and cytokine interactions.

Molecular autopsy has recently been gaining attention as a means of postmortem diagnosis; however, it is usually performed using the victim's blood sample at the time of death. Here, we report the first case of a deceased infant with Brugada syndrome whose diagnosis was made with banked cord blood. A seemingly healthy 1-year-old male infant collapsed while having a fever; this collapse was witnessed by his mother.

Objective: This review aimed to synthesize the experiences of patients with metachromatic leukodystrophy, adrenoleukodystrophy, or Krabbe disease and the experiences of their families.

Introduction: Leukodystrophies are metabolic diseases caused by genetic mutations. There are multiple forms of the disease, varying in age of onset and symptoms.

Background: The number of patients with multimorbidity has increased due to the aging of the global population. Although the World Health Organization has indicated that multimorbidity will be a major medical problem in the future, the appropriate interventions for patients with multimorbidity are currently unknown. This study aimed to investigate whether nurse-led interprofessional work is associated with improved prognosis in heart failure patients with multimorbidity aged ≥65 years who were admitted in an acute care hospital.

Purpose: Vascular distribution is important information for diagnosing diseases and supporting surgery. Photoacoustic imaging is a technology that can image blood vessels noninvasively and with high resolution. In photoacoustic imaging, a hemispherical array sensor is especially suitable for measuring blood vessels running in various directions.

Objectives: We aimed to psychometrically evaluate and validate a Japanese version of the Social Functioning in Dementia scale (SF-DEM-J) and investigate changes in social function in people with dementia during the coronavirus disease-19 (COVID-19) pandemic.

Design: We interviewed people with mild cognitive impairment (MCI) and mild dementia and their caregivers during June 2020-March 2021 to validate patient- and caregiver-rated SF-DEM-J and compared their scores at baseline (April 2020 to May 2020) and at 6-8 months (January 2021 to March 2021) during a time of tighter COVID-19 restrictions.

Alzheimer's disease (AD) is a multi-stage neurodegenerative disorder characterized by beta-amyloid accumulation, hyperphosphorylated Tau deposits, neurodegeneration, neuroinflammation, and cognitive impairment. Recent studies implicate CD8 T cells as neuroimmune responders to the accumulation of AD pathology in the brain and potential contributors to toxic neuroinflammation. However, more evidence is needed to understand lymphocytes in disease, including their functional states, molecular mediators, and interacting cell types in diseased brain tissue.

There is some biological plausibility that exogenous melatonin plays a role in preventing liver carcinogenesis. There has been little research on the association between melatonin intake in a normal diet and health outcomes. We evaluated the association between dietary melatonin intake and the incidence of liver cancer in a population-based prospective study in Japan.
