The Eye4HK Meme and the Construction of an Injustice Frame

The territory-wide protest in Hong Kong in 2019, originated from a proposed amendment bill on the extradition of fugitives to China which triggered massive protests. In an incident, the police shot a female medic in the eye which outraged the public. A Korean celebrity initiated an online movement by uploading a selfie covering his right eye to Twitter showing solidarity with the victim. The eye-covered image signifies the girl who lost her eye as a political victim, gaining wide sympathy. The sub-campaign constructed an image of resistance against police brutality which strengthened the wider movement in Hong Kong and helped to win support in other parts of the world. The campaign also linked the emotions of the two places by recalling Koreans’ memory of their historical struggle for democracy. The sub-campaign generated symbolic resources accumulating through the production and reproduction process online and subsequently benefited the wider social movement for political change

Advance directive and end-of-life care preferences among Chinese nursing home residents in Hong Kong

OBJECTIVES: The objectives of the present study were to describe the knowledge and preferences of Hong Kong Chinese older adults regarding advance directives and end-of-life care decisions, and to investigate the predictors of preferences for advance directive and community end-of-life care in nursing homes. METHODS: This was a cross-sectional survey conducted in 140 nursing homes in Hong Kong. A total of 1600 cognitively normal Chinese older adults were recruited. Information on demographics, social, medical diseases, preferences of end-of-life care decisions, and advance directives were collected by face-to-face questionnaire interviews. RESULTS: The mean age of the participants was 82.4 years; 94.2% of them would prefer to be informed of the diagnosis if they had terminal diseases and 88.0% preferred to have their advance directives regarding medical treatment in the future. Approximately 35% would prefer to die in their nursing homes. The significant independent predictors for the preference of advance directive included asking for relatives' advice, wishing to be informed of their terminal illness diagnoses, absence of stroke, and having no problems in self-care in European Quality of Life-5 Dimensions. For the preference for community end-of-life care and dying in nursing homes, the independent predictors included older age, not having siblings in Hong Kong, Catholic religion, nonbeliever of traditional Chinese religion, not receiving any old age allowance, lower Geriatric Depression Scale score, and being residents of government-subsidized nursing homes. CONCLUSIONS: Most of our cognitively normal Chinese nursing home older adults prefer having an advance directive, and one-third of them would prefer to die in nursing homes.postprin

Children with Respiratory Disease Associated with Metapneumovirus in Hong Kong

Human metapneumovirus (HMPV) is a newly discovered pathogen thought to be associated with respiratory disease. We report the results of a study of 587 children hospitalized with respiratory infection over a 13-month period. HMPV was detected in the nasopharyngeal aspirates from 32 (5.5%) children by reverse transcription-polymerase chain reaction. HMPV infection was associated with clinical diagnoses of pneumonia (36%), asthma exacerbation (23%), or acute bronchiolitis (10%). When compared to those with respiratory syncytial virus infection, children with HMPV infection were older, and wheezing was more likely to represent asthma exacerbation rather than acute bronchiolitis. HMPV viral activity peaked during the spring-summer period in Hong Kong. Phylogenetically, all HMPV virus strains from Hong Kong belonged to one of the two genetic lineages previously described. HMPV contributed to 441.6 hospital admissions per 100,000 population <6 years of age

Dementia and risk of visual impairment in Chinese older adults

We had previously identified visual impairment increasing risk of incident dementia. While a bi-directional vision-cognition association has subsequently been proposed, no study has specifically examined the longitudinal association between dementia and incidence of clinically defined visual impairment. In this territory-wide community cohort study of 10,806 visually unimpaired older adults, we examined their visual acuity annually for 6 years and tested if dementia at baseline was independently associated with higher risk of incident visual impairment (LogMAR ≥ 0.50 in the better eye despite best correction, which is equivalent to moderate visual impairment according to the World Health Organization definition). By the end of Year 6, a total of 3151 (29.2%) participants developed visual impairment. However, we did not find baseline dementia associating with higher risk of incident visual impairment, after controlling for baseline visual acuity, cataract, glaucoma, diabetes, hypertension, hypercholesterolemia, heart diseases, stroke, Parkinson's disease, depression, hearing and physical impairments, physical, intellectual and social activities, diet, smoking, age, sex, educational level, and socioeconomic status. Among different covariables, baseline visual acuity appears to be more important than dementia in contributing to the development of visual impairment. Our present findings highlight the need for re-evaluating whether dementia is indeed a risk factor for visual impairment

Assay of pleural fluid interleukin-6, tumour necrosis factor-alpha and interferon-gamma in the diagnosis and outcome correlation of tuberculous effusion

AbstractObjective: To assess the usefulness of interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ) in the diagnosis and prediction of outcome of pleural tuberculosis.Patients and methods: Pleural fluid from 32 TB and 34 non-TB patients was sent for assay of IL-6, TNF-α and IFN-γ. Clinical parameters at presentation and residual pleural scarring at completion of treatment were assessed for pleural TB cases.Results: The pleural fluid levels of IL-6, TNF-α and IFN-γ in TB patients were significantly higher than those with non-TB effusions (P values of <0.001, 0.018 and <0.001, respectively by independent t-test). Utility of these cytokines for diagnosis of pleural TB was evaluated using receiver operating characteristic (ROC) curve analysis. The cut-off values for IL-6, TNF-α and IFN-γ determined in this analysis were 4000, 4 and 60pg/ml respectively, and their sensitivity and specificity were 90.6% and 76.5%, 90.6% and 79.4%, 100% and 100%, respectively. The pretreatment pleural fluid IL-6 levels had a positive correlation with the number of febrile days after treatment (Pearson correlation test: r=0.60, P=0.009). A negative correlation was found between the percentage reduction in pleural fluid cytokines after 2 weeks treatment and the extent of residual pleural scarring (IL-6: r=–0.62, P=0.041; TNF-α: r=–0.65, P=0.030; IFN-γ: r=–0.83, P=0.002).Conclusion: Pleural fluid IL-6, TNF-α and IFN-γ assays are useful in the diagnosis of pleural TB. The initial IL-6 level correlates with the number of febrile days. The percentage change of cytokines after 2 weeks of treatment also helps to predict residual pleural scarring
