Preliminary study of the effect of the web application on caregiver burden in dementia and behavioural and psychological symptoms of dementia.

This study aimed to investigate if our web application could be a viable intervention for providing caregivers with information on resilient coping strategies for the reduction of their burden, thereby leading to the alleviation of behavioural and psychological symptoms of dementia (BPSD). We recruited outpatients with dementia and informal caregiver dyads at Nagoya University Hospital from April 2022 to October 2022. The caregivers were asked to have the web application installed on their smartphones during the study period and answer the following two self-administered questionnaires once a month for 3 months: (a) Abe's BPSD Score (ABS), which assesses BPSD, and (b) the Japanese version of the Zarit Caregiver Burden Interview (J-ZBI) score, which measures caregiver burden.

Production of a heterozygous exon skipping model of common marmosets using gene-editing technology.

Nonhuman primates (NHPs), which are closely related to humans, are useful in biomedical research, and an increasing number of NHP disease models have been reported using gene editing. However, many disease-related genes cause perinatal death when manipulated homozygously by gene editing. In addition, NHP resources, which are limited, should be efficiently used.
