Eye-tracking-based cognitive assessment efficiently detects mild cognitive decline in the predementia stage.

INTRODUCTION: The early detection of cognitive decline is key to maximizing the benefits of preventive and therapeutic interventions against dementia. Generally, dementia is first assessed by interview-based neuropsychological tests, but the lengthy interview and mental stress during the assessment process make screenings inefficient. We previously developed a rapid screening test for dementia using an eye-tracking technology (eye tracking-based cognitive assessment, ETCA) and reported its utility for clinically detecting cognitive impairment in dementia cases. However, the ETCA's performance in detecting people with mild cognitive decline, which is the major target population for dementia-prevention strategies, remains insufficiently examined. Therefore, this study aimed to evaluate the ETCA's performance in individuals aged 40 years and older (n = 94, mean age; 61.0 [SD 13.1] years) without being formally diagnosed with dementia. METHODS: All participants underwent both the ETCA and neuropsychological tests, including the Mini-Mental State Examination (MMSE), Rivermead Behavioral Memory Test (RBMT), and Addenbrooke's Cognitive Examination-III (ACE-III) on the same day. We examined the correlations in scores between the ETCA and each neuropsychological test. Furthermore, we selected participants who earned normal scores in each neuropsychological test and evaluated the ETCA's performance in this subgroup. RESULTS: Participants' ETCA scores correlated significantly with their scores on neuropsychological tests, including the MMSE, RBMT, and ACE-III. Notably, the ETCA scores correlated with the RBMT or ACE-III scores in individuals who showed normal scores in each neuropsychological test. CONCLUSION: The ETCA has the potential to screen mild cognitive decline efficiently at the predementia stage in nonclinical settings.

A mixed-methods study on the pharmacological management of pain in Australian and Japanese nursing homes.

BACKGROUND: Understanding how analgesics are used in different countries can inform initiatives to improve the pharmacological management of pain in nursing homes. AIMS: To compare patterns of analgesic use among Australian and Japanese nursing home residents; and explore Australian and Japanese healthcare professionals' perspectives on analgesic use. METHODS: Part one involved a cross-sectional comparison among residents from 12 nursing homes in South Australia (N = 550) in 2019 and four nursing homes in Tokyo (N = 333) in 2020. Part two involved three focus groups with Australian and Japanese healthcare professionals (N = 16) in 2023. Qualitative data were deductively content analysed using the World Health Organization six-step Guide to Good Prescribing. RESULTS: Australian and Japanese residents were similar in age (median: 89 vs 87) and sex (female: 73% vs 73%). Overall, 74% of Australian and 11% of Japanese residents used regular oral acetaminophen, non-steroidal anti-inflammatory drugs or opioids. Australian and Japanese healthcare professionals described individualising pain management and the first-line use of acetaminophen. Australian participants described their therapeutic goal was to alleviate pain and reported analgesics were often prescribed on a regular basis. Japanese participants described their therapeutic goal was to minimise impacts of pain on daily activities and reported analgesics were often prescribed for short-term durations, corresponding to episodes of pain. Japanese participants described regulations that limit opioid use for non-cancer pain in nursing homes. CONCLUSION: Analgesic use is more prevalent in Australian than Japanese nursing homes. Differences in therapeutic goals, culture, analgesic regulations and treatment durations may contribute to this apparent difference.

Impact of nurse-led interprofessional work in older patients with heart failure and multimorbidity: A retrospective cohort study.

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. Methods: Patients who were admitted to the cardiovascular medicine ward of an acute care hospital in Osaka, Japan, and underwent nurse-led interprofessional work from April 1, 2017 to March 31, 2020, and from April 1, 2014 to March 31, 2016, were included in this retrospective cohort study. The patients were matched by age, sex, and New York Heart Association classification. The nurse-led interprofessional work was based on a three-step model that incorporates recommendations from international guidelines for multimorbidity. The primary outcome was all-cause mortality. Results: The mean age of the participants was 80 years, and 62 % were men. The nurse-led interprofessional work group showed a significant difference in all-cause mortality compared with the usual care group (hazard ratio, 0.45; 95 % confidence interval [CI], 0.29-0.69; P < 0.001). Compared with the usual care group, the nurse-led interprofessional work group exhibited a 7 % difference in mortality rate at 1-year post-discharge (P < 0.001). Conclusions: Nurse-led interprofessional work may reduce the all-cause mortality in older patients with heart failure and multimorbidity.
