Objectives: To develop a cross-cultural dialogue for enriching our understanding of how an ethical environment can be constructed in fostering tube-feeding decisions in patients with advanced dementia (AD). Design & Data Source: Drawing on the findings of two prospective case studies conducted in Boston and Hong Kong, this paper compares the decision-making patterns of forgoing tube feeding for AD patients and their emergent ethical dilemmas typified in a special dementia care unit in Boston (BCU) and a long-term care unit in Hong Kong (HKCU). Findings: Differences in forgoing tube feeding decision are delineated in the two places. No-tube-feeding practice was sustained in BCU in two ways: advance decision-making with respect paid to the patient's wishes and advance proxy decision-making focused on patient comfort. With life preservation as the prevailing value in the Hong Kong medical system, only strong family request coupled with medical evidence of patient's ability to continue hand-feeding that tube feeding would be discontinued. All patients died with some form of artificial feeding. Conclusion: A paradigm shift of values underpinning the practice of forgoing tube feeding in the context of palliative care is observed in three aspects. First, the emphasis on prognostication based on biomedical markers in predicting the length of survival is shifted to a focus on the "diagnosis of dying". Second, the overriding concern in conventional medical practice with preserving life is shifting to an overriding concern of "what is best for the patient." Third, in the last days of life, the conventional approach of "trying to do everything for the patient" had shifted from a technological to a relational one. Palliative measures for relieving discomfort and providing a peaceful and dignified environment in which the patient could die are the primary concern. Although the predominant medical culture in Hong Kong is biomedical, voices from the patients and family members challenge this conventional practice, and suggest that the alternative model may be a better choice.

NURSING students , *NURSING ethics - Abstract
This paper reports part of a longitudinal research project, which sought to capture students’ conceptualization of caring practice as they progressed to different levels of study in a nursing diploma programme in Hong Kong. Model emulation was found to be an effective means of focusing students’ learning processes on the moral aspects of nursing practice. The theory of model emulation from a Chinese perspective and how it is applied to create a learning context to allow students to acquire a moral sense of nursing are discussed. The participating students are invited to be sincere enquirers in the pursuit of the good embedded in practice through introspective self-examination and dialogue. They are asked to describe and share their experience of positive and negative examples of nursing in written accounts. Van Kaam’s phenomenological method was adopted to explicate the good and bad constituents of nursing from these examples, with the students assuming an active role in the explication process. The explication reveals that the students were able to articulate the good and bad practices in a variety of patient care situations. [ABSTRACT FROM AUTHOR]

MEDICAL ethics , *LEGAL status of patients - Abstract
While the movement to ensure patient’s rights to information and informed consent spreads throughout the world, patient rights of this kind have yet to be introduced in mainland China. Nonetheless, China is no different from other parts of the world in that nurses are expected to shoulder the responsibility of safeguarding patients’ best interests and at the same time to uphold their right to information. This paper expounds on the principle of protectiveness grounded in traditional Chinese medical ethics concerning the practice of informed consent. Nurses in China have a moral obligation to treat patients with sincerity. This notion carries a strong sense of parental protectiveness. As far as information-giving is concerned, nurses in China are ambivalent about the notion of truthfulness. The findings of an empirical study undertaken in seven Chinese cities reveal that nurses in China experience similar difficulties related to the disclosure of information as their counterparts in other parts of the world. A nurse’s narrative, the Chan case, is used to illustrate the typical difficult situation that nurses in China often encounter in looking after vulnerable patients who would like to learn more about their therapeutic regimens. The moral tension embedded in nursing practice is analysed. It is found that most nurses would prefer to tell the truth to patients, but their primary ethical justification is not that of respect for patients’ autonomy or safeguarding patients’ right to self-determination. Rather, it is basically beneficent in nature; that is, they base their decision to reveal the truth on whether or not patients will receive more relevant treatment and better nursing care.

- Abstract
Background: Tuberculous meningitis (TBM) is the most severe form of tuberculosis. Microbiological confirmation is rare and treatment is often delayed. Early diagnosis and immediate initiation of treatment are essential for effective TBM control. A systematic review was performed in this study to assess the diagnostic accuracy of detecting antibodies against Mycobacterium tuberculosis in the cerebrospinal fluid (CSF), according to standard methods. Test performance was summarized using a bivariate random-effects meta-analysis., Methods: Studies were identified by a search of the literature, up to July 25, 2015, in the EMBASE and MEDLINE databases via Ovid SP and PubMed. The Cochrane Library was also searched for original, peer-reviewed molecular epidemiology studies that reported the diagnosis of TBM based on antibody detection in the CSF., Results: Thirty-six articles (58 studies) were identified. The sensitivity of antibody detection was 0.75 (95% confidence interval (CI) 0.66-0.82), specificity was 0.98 (95% CI 0.96-0.99), and the area under the receiver operating characteristic curve (AUROC) was 0.97 (95% CI 0.95-0.98). By subgroup analysis, the detection of anti-M37Ra was the highest (AUROC 0.99, 95% CI 0.98-1.00), followed by anti-antigen 5 (AUROC 0.99, 95% CI 0.97-0.99) and anti-M37Rv (AUROC 0.97, 95% CI 0.95-0.98)., Conclusions: For the early diagnosis of TBM based on antibodies in the CSF, the detection of anti-M37Ra, anti-antigen 5, or anti-M37Rv provides the greatest sensitivity and specificity., (Copyright © 2016 The Author(s).

- Abstract
Since 2002, hospitals have to report to Nursing Service Department, Hospital Authority Head Office on the pressure ulcer trends for risk management in Hong Kong. In line with the strategy, hospitals have designed their own patient observation records and reporting forms for monthly analysis and reporting of in-patient hospital acquired pressure ulcers. The incidence rates of individual hospital and its specialties are then calculated manually or using electronic spread sheets. However, the diversity in data definition and vocabulary use generates difficulties in communication among professionals and hospital managers. The development of the system would help to standardize the requirements and to reduce the time required for generating trends and ulcer information. The system also lays the foundation for future systems integration with the changing information system infrastructure.

- Abstract
Adeno-associated virus-2 (AAV) can integrate in a site-specific manner to human chromosome 19 and is currently in phase I clinical trials for cystic fibrosis (CF) at Johns Hopkins Hospital. The goal of this study was to determine the fate of recombinant AAV containing the CFTR cDNA (AAV-CFTR) in an immortalized pseudotetraploid CF bronchial epithelial cell line (IB3-1) established from a patient with CF. Fluorescence in situ hybridization (FISH) and Southern blotting of DNA from IB3-1 cells infected with wild-type (wt) or recombinant AAV-CFTR were performed. CFRH2, an IB3-1 cell line with an estimated 15-20 integrated copies of CFTR cDNA, was used to test FISH sensitivity. All metaphase spreads had integrated copies: a single site in 36 of 56 (64.3%) and two sites within the same metaphase spread in 20 of 56 (35.7%). 3-CF-8, an IB3-1 cell line with integration of a partial CFTR cDNA (3.9 kb) was also analyzed by FISH. Integration was observed in 56 of 157 (35.7%) metaphase spreads examined. IB3-1 cells infected with wild-type AAV showed integration in 51 of 86 (59%) metaphase spreads examined. Of 51 integrations, 48 (94%) were to chromosome 19. Examination of 67 metaphase chromosome spreads of IB3-1 cells infected with AAV-CFTR vector (Azero) identified four integrations (6%) to different chromosomes. No integration was to chromosome 19 which differs significantly (P < 0.0001) from wild-type AAV. We then analyzed the A35 cell line, a clone of Azero selected for stable CFTR expression. Genomic DNA from A35 cells did not show a single site of integration; however episomal AAV-CFTR sequences were abundant in the low molecular weight DNA fraction. Examination of 68 metaphase chromosome preparations identified eight distinct integrations, none to chromosome 19. These studies show that FISH is sensitive for the detection of a partial CFTR cDNA integration. Wild-type AAV integrates in a predominantly site-specific fashion. Recombinant AAV-CFTR integrates at low frequency in a nonspecific manner and persists in episomal form in this epithelial cell line.
