Background:Criteria for determining brain death (BD) vary between China and the United States. We reported the results of an investigation designed to compare procedures to determine BD in two countries.Methods:The latest criteria in the United states were published in 2010. The latest criteria in China were published in 2009. We used these two types of BD criteria to evaluate patients who were considered to be BD. The time, cost, and accuracy of the diagnosis were compared.Results:From January 1, 2012 to October 8, 2013, there were 37 patients which were applied for BD evaluation in the Neurological Intensive Care Unit of Beijing Tiantan Hospital. The cause of coma were known as subarachnoid hemorrhage (18 patients, 48.6%), intracerebral hemorrhage (8 patients, 21.6%), cerebral ischemia (9 patients, 24.3%), brain stem tumor (1 patient, 2.7%), and intracranial infection (1 patient, 2.7%). The clinical examinations were done for all of the patients except 1 patient who had low blood pressure. Three patients had brainstem reflexes that were excluded from BD. Twenty-five patients had apnea tests, and 20 tests were completed that were all positive. Confirmatory tests were completed differently: Transcranial Doppler (30 patients, positive rate 86.7%), electroencephalogram (25 patients, positive rate 100%), and somatosensory evoked potential (16 patients, positive rate 100%). Thirty-three patients were diagnosed BD by criteria of the United States. Only 9 patients were diagnosed BD by Chinese criteria. The use of time and money in the USA criteria was obviously fewer than those in Chinese criteria (P = 0.000).Conclusion:Compared with BD criteria of the United States, Chinese criteria were stricter, lower positive rate, more cost in money and time, and more reliable by families and doctors.

Health literacy has been identified as one vital determinant of public health and healthy behaviors, but very few studies regarding infectious disease prevention have been found. This descriptive cross-sectional study aimed to validate the pathway of infectious disease-specific health literacy (IDSHL), COVID-19 (coronavirus disease 2019) preventive behaviors, and their determinants. A sample of 1459 casino workers in Macao was eligible for analysis. The concept model was verified with a comparative fit index of 0.937 and goodness-of-fit index of 0.971. Government responses was a significant determinant of situational factors (helpfulness of health information, resource accessibility, and organizational training adequacy), while situational factors showed a direct effect on COVID-19 preventive behaviors. Education and organization training adequacy was the strongest influencing factor of IDSHL, which should be a key target of intervention programs for COVID-19.

Based on Construal Level Theory (CLT), the youth and older adults have different psychological distances towards dementia that may lead to different dementia knowledge and attitudes. A cross-sectional survey among 239 youth and 62 older adults using a two-step sampling approach in Macao aimed to examine the hypothesis. Results showed older adults had a higher score of dementia knowledge (F(1,299) = 45.692, p <0.001) but a lower score of dementia attitudes (F(1,299) = 161.887, p <0.001) compared to the youth. Age group explained the majority of the variances in the hierarchical multiple regressions for dementia knowledge (R2 = 0.178, F = 9.059, p < 0.001) and for dementia attitudes (R2 = 0.399, F = 24.233, p < 0.001), which are β = 0.47 and −0.56, respectively. Thus, the hypothesis was supported and revealed an interesting pattern of dementia knowledge and attitudes among the youth and older adults. From the CLT perspective, the study implies that reducing and bridging the psychological distance of dementia would probably be an effective strategy to increase dementia awareness among young people, and intergenerational programs may be a good option to increase community acceptance and support for people with dementia.

Background Dementia-friendly community has been promoted in Macao since 2016. There is no study investigating the understanding of nor attitudes towards dementia among public contact staff in Macao. This study aimed to (i) understand the level of knowledge of dementia, (ii) examine the attitudes towards people living with dementia, and (iii) explore the associated factors of the willingness to help people with dementia symptoms among police officers, bank officers, bus drivers, and building superintendents. Methods A cross-sectional survey was conducted between January and May 2019 using a structured questionnaire. Results A total of 351 valid questionnaires were received. Building superintendents had more knowledge while police officers and bank officers had more positive attitudes. All practitioners were more willing to help people with dementia symptoms when they were on official duty. Participants who had more knowledge about dementia were associated with a higher willingness to help people with dementia symptoms.
