The incidence of infection (CDI) has been previously reported in a number of studies. However, data collected from the Chinese population is limited. In the present study, the diversity of the toxin genes, and of 57 () isolates from a Chinese population were investigated by polymerase chain reaction (PCR) (38 AB, 14 AB and 5 AB). Quantitative PCR was used to check the expression of these two genes and it was found that the genes were not expressed by all the strains. The absence of or expression in certain strains could be due to the lower expression of and the higher expression of , which are positive and negative regulators for these two toxin genes, respectively. In addition, the antimicrobial susceptibilities of 57 isolates were investigated. Therefore, these data would aid in the future prevention of CDI outbreaks and improve the understanding of the infection.

Background: Understand individuals' self-perception of aging is crucial for promoting a positive aging experience, better health with good quality of life, addressing activities participation, and can help by advocating policies and interventions that support the diverse needs of an aging population. This study aims to examine the validity and reliability of the Chinese version of BAPQ (C-BAPQ) for the healthy older people by assessing the content validity, test-retest reliability, and correlational analyses with mental health by Depression, Anxiety, and Stress Scale (DASS-21), quality of life by the Short Form 36 Health Survey (SF-36) and activity participation by the Model of Human Occupation Screening Tool (MOHOST). Moreover, to study the factor structure of the Chinese version of BAPQ (C-BAPQ) by using exploratory factor analysis.

Background: This prediction model quantifies the risk of cognitive impairment. This aim of this study was to develop and validate a prediction model to calculate the 6-year risk of cognitive impairment.
Methods: Participants from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) 2008-2014 and 2011-2018 surveys were included for developing the cognitive impairment prediction model.

Background: Asian American, Native Hawaiian, and Pacific Islander (AANHPI) populations are underrepresented in Alzheimer's disease and related dementias (ADRD) research, despite being the fastest growing racial group in the United States. The Collaborative Approach for AANHPI Research and Education (CARE) registry aims to create a sustainable research recruitment source to address this need.
Method: Participants can enroll online, by phone, or in-person by completing an enrollment survey in English, Chinese (Simplified/Traditional), Hindi, Korean, Samoan, or Vietnamese.

Background: Studies show that tube feeding does not improve clinical outcomes, and professional guidelines recommend against its use for individuals with advanced dementia. Yet, our preliminary work demonstrates a preference for tube feeding among Chinese-American dementia caregivers. We propose linguistic and cultural adaptation of "Making Choices: Feeding Options for Patients with Dementia (MCFODA) to create the Chinese version of this efficacious decision aid intervention.

University of Queensland, Brisbane, QLD, Australia.
Background: Dementia is highly stigmatised, misperceived as a mental illness, and considered a normal part of ageing by people from culturally and linguistically diverse backgrounds in Australia. There is a lack of valid and reliable scale to measure their dementia attitudes. This study aimed to cross-culturally translate and validate a dementia attitudes scale in Arabic, Vietnamese, Chinese, and Greek communities as they represent the main languages spoken throughout Western Sydney, Australia.
