Removing the Digital Divide for Senior Web Users

It is hard for the elderly to use the internet to find the resource they want. Usually help is needed for them to complete the task on the technology things. The main reason for this project is to research ideas on encourage senior people to make use of the web to locate helps they want, such as finding volunteers and professional helps. The scope of this project is to develop a new way of web access and content presentation methodologies that let senior people getting help from volunteers and various service providers more easily that incorporates social networking technology e.g. Facebook. By incorporating the social network web site like Facebook into the web application, senior people will be able to find volunteering help or other related service providers through social networking. Volunteers will show up in Google map in search results for senior to easily locate helps. Senior people can also search for self help videos tutorials through the web application search engine. A mobile version of the senior user application will also be developed for easy access on the road. Other features that benefit senior users includes voice input, control / content posting and collaborative social networking where a sponsors would sponsor a help task volunteer undertake

Intra-operative spinal chord monitoring

Spinal surgery carries a small but definite risk of damaging the spinal chord. Early detection and correction of any reversible insult to the chord is important. An intra-operative 'wake-up' test has been used to monitor the chord function for more than 20 years. However, it has its limitations and disadvantages. Advances in electronics have facilitated the development and clinical application of electrophysiological methods in assessing the integrity of the spinal chord during surgery. It is now possible to monitor the spinal chord during surgery using various evoked potentials techniques.published_or_final_versio

The Embryotrophic Activity of Oviductal Cell-derived Complement C3b and iC3b, a Novel Function of Complement Protein in Reproduction

The oviduct-derived embryotrophic factor, ETF-3, enhances the development of trophectoderm and the hatching process of treated embryos. Monoclonal anti-ETF-3 antibody that abolishes the embryotrophic activity of ETF-3 recognized a 115-kDa protein from the conditioned medium of immortalized human oviductal cells. Mass spectrometry analysis showed that the protein was complement C3. Western blot analysis using an antibody against C3 confirmed the cross-reactivities between anti-C3 antibody with ETF-3 and anti-ETF-3 antibody with C3 and its derivatives, C3b and iC3b. Both derivatives, but not C3, were embryotrophic. iC3b was most efficient in enhancing the development of blastocysts with larger size and higher hatching rate, consistent with the previous reported embryotrophic activity of ETF-3. Embryos treated with iC3b contained iC3b immunoreactivity. The oviductal epithelium produced C3 as evidenced by the presence of C3 immunoreactivity and mRNA in the human oviduct and cultured oviductal cells. Cyclical changes in the expression of C3 immunoreactivity and mRNA were also found in the mouse oviduct with the highest expression at the estrus stage. Molecules involving in the conversion of C3b to iC3b and binding of iC3b were present in the human oviduct (factor I) and mouse preimplantation embryo (Crry and CR3), respectively. In conclusion, the present data showed that the oviduct produced C3/C3b, which was converted to iC3b to stimulate embryo development.postprin

Advance directive and preference of old age home residents for community model of end-of-life care in Hong Kong

Key Messages: 1. Among 1600 cognitively normal elderly persons living in old age homes in Hong Kong, 88% preferred palliative treatments that could keep them comfortable and free from pain, and 88% agreed to have advance directives. Factors that favour having advance directives among Chinese elders included the practice of asking for relatives’ advice in medical decisions, wishing to be informed of their terminal illness diagnoses, absence of a stroke history, and having no problems in self-care. 2. Approximately one third of old age home residents would accept dying in place. Older age, religion (Catholic or non-believer of traditional Chinese religion), having a better mood score (Geriatric Depression Scale), having no siblings, not receiving an old age allowance, and being a resident of subvented old age homes were independent predictors of preference for community end-of-life care and dying in place. 3. End-of-life care in the hospital was expensive. The total bed-day costs for the 2084 deaths in the two clusters for the index death episode, cumulative 3, 6, and 12 months of hospitalisation were HK$65 474 591, HK$82 543 510, HK$100 170 949, and HK$108 960 348, respectively. The annual cost-savings in hospitalisation bed-days would be HK$177 million when about 30% of elders accepted dying in their old age homes. 4. Elderly residents were willing to pay an additional fee for community end-of-life care services in old age homes. Both the services of the doctor and old age home staff were important attributes. Hence, elderly people were prepared to use more community end-of-life care if better staff and doctor services were provided.published_or_final_versio

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

Is acupuncture effective in controlling gagging when taking an alginate impressions?

Our community health project aimed to (1) identify the prevalence of gagging among patients attending the Prince Philip Dental Hospital; and to identify socio-demographic variations in reported gagging experiences; and (2) perform a pilot study to evaluate the effectiveness of acupuncture in the control of gagging in the dental setting. Methods: A survey on reported gagging experiences was conducted among patients attending our hospital involving a convenience sample of 225 patients. Participants who reported to previously gag in the dental setting were invited to participate in a pilot study to evaluate the effectiveness of acupuncture in controlling gagging when taking an upper alginate impression. Participants were randomized to receive acupuncture stimulation at a site reported to be effective in the control of gagging on the lower lip (point CV 24) or at a sham site on the upper lip (point GV 26) on their first visit and at their second visit to receive the alternative acupuncture stimulation. Results: The response rate to the survey was 81.3% (183/225). Approximately a third (58/183) reported to have experienced gagging in the dental setting and most frequently encountered this when having a dental impression (among approximately a quarter of participants - 44/183). Half (95/183) reported gagging while performing oral self-care. Four in ten participants (73/183) reported some stress visiting the dentist related to gagging. Sociodemographic variations in reported gagging experiences were evident with respect to age, gender and education level. The response rate to the pilot study was 92.3% (36/39). There was no significant difference in the prevalence of gagging when acupuncture was applied to the test site compared to when acupuncture was applied to the sham site on dental examination (p>0.05) or when taking an upper alginate impression (p>0.05). Conclusions: Gagging in a relative common experience reported by patients attending our hospital – in daily life, in the dental setting and in performing oral self-care. Socio-demographic variations in the prevalence of gagging were apparent. The pilot study does not support the use of acupuncture in controlling gagging in the dental setting.published_or_final_versio

The concerns and experiences of patients with lumbar spinal stenosis regarding prehabilitation and recovery after spine surgery: A qualitative study

Objectives To improve our understanding of patients’ perspectives regarding: (1) the decision making and prehabilitation before lumbar spinal stenosis (LSS) surgery; and (2) their postoperative experiences. Design Qualitative research with semi-structured interviews. Setting General community Participants Individuals received (n=10) and did not receive (n=15) prehabilitation before LSS surgery were recruited at the 6-month postoperative follow-up (8 females; average age: 67.7±6.7 years) by purposive sampling. Additionally, one participant invited her daughter to accompany her in an interview. Interventions Not applicable Main outcome measures Concerns and experiences of patients with LSS regarding prehabilitation and recovery after spine surgery. Results Thematic analysis was conducted to identify four themes inductively: (1) sources of information about LSS surgery; (2) factors affecting the surgical decision making; (3) attitudes toward prehabilitation; and (4) postoperative recovery. All participants desired to have more preoperative education to inform their surgical decision making. There were mixed opinions regarding the perceived benefits of prehabilitation because some individuals hesitated to participate in prehabilitaiotn due to their symptoms, or the cost or time of travelling. Many participants expected some or even complete relief of LSS-related symptoms after surgery. However, not all participants experienced the expected postoperative improvements. Some participants only experienced temporary symptomatic relief, while others experienced new postoperative symptoms. Patients generally found that postoperative exercises taught by physiotherapists were useful although their compliance decreased over time. Conclusions Our study highlights the need for better preoperative LSS education. Since face-to-face prehabilitation or postoperative rehabilitation may not be feasible for all patients, future studies should explore whether online-based prehabilitation or postoperative rehabilitation may benefit certain patient subgroups
