The well-being among college students living on campus: a focus on morning-evening preference

Conference Theme: The Development of Psychology in Hong Kong: Past, Present, and FuturePoster Presentation: no. P-36BACKGROUND/RATIONALE: Getting into college, students can choose to live on-or off-campus. While on-campus residence allows easier access to campus facilities, its impact on college students’ well-being remains unclear. This research aims to study the well-being(indicated by mood, sleep and quality-of-life) among students living on/off campus. We also intend to explore the factors leading students to discontinue living on campus. While studies showed that morning-evening preference(M/E) has a role in college students’ well-being …published_or_final_versio

ICTs, development and peace : spectrum for constructive debate and engagement

In this age of the so-called ICTs and 'digital revolution', majority of the world is hungry, thirsty, poor, insecure and conflict-riven. Common mind-boggling questions include: why are large swathes of the world so deprived and insecure? What are the factors mitigating against global equality? How and why are ICTs appropriated by some parts of the world, yet virtually non-existant in others? Are there any prospects for the developing world? These questions frame the focus of the article, and articles and comementaries that follow. While the picture may look gloomy, it is noted that there is scope for hope and change. All contributions in this Volume [volume 1, number 2] share this conviction: they are critically diagnostic, yet optimistically presscriptive

Clinical Characteristics and Transmission of COVID-19 in Children and Youths During 3 Waves of Outbreaks in Hong Kong

IMPORTANCE: Schools were closed intermittently across Hong Kong to control the COVID-19 outbreak, which led to significant physical and psychosocial problems among children and youths. OBJECTIVE: To compare the clinical characteristics and sources of infection among children and youths with COVID-19 during the 3 waves of outbreaks in Hong Kong in 2020. DESIGN, SETTING AND PARTICIPANTS: This cross-sectional study involved children and youths aged 18 years or younger with COVID-19 in the 3 waves of outbreaks from January 23 through December 2, 2020. Data were analyzed from December 2020 through January 2021. MAIN OUTCOMES AND MEASURES: Demographic characteristics, travel and contact histories, lengths of hospital stay, and symptoms were captured through the central electronic database. Individuals who were infected without recent international travel were defined as having domestic infections. RESULTS: Among 397 children and youths confirmed with COVID-19 infections, the mean (SD) age was 9.95 (5.34) years, 220 individuals (55.4%) were male, and 154 individuals (38.8%) were asymptomatic. There were significantly more individuals who were infected without symptoms in the second wave (59 of 118 individuals [50.0%]) and third wave (94 of 265 individuals [35.5%]) than in the first wave (1 of 14 individuals [7.1%]) (P = .001). Significantly fewer individuals who were infected in the second and third waves, compared with the first wave, had fever (first wave: 10 individuals [71.4%]; second wave: 22 individuals [18.5%]; third wave: 98 individuals [37.0%]; P < .001) or cough (first wave: 6 individuals [42.9%]; second wave: 15 individuals [12.7%]; third wave: 52 individuals [19.6%]; P = .02). Among all individuals, 394 individuals (99.2%) had mild illness. One patient developed chilblains (ie, COVID toes), 1 patient developed multisystem inflammatory syndrome in children, and 1 patient developed post–COVID-19 autoimmune hemolytic anemia. In all 3 waves, 204 patients with COVID-19 (51.4%) had domestic infections. Among these individuals, 186 (91.2%) reported having a contact history with another individual with COVID-19, of which most (183 individuals [90.0%]) were family members. In the third wave, 18 individuals with domestic infections had unknown contact histories. Three schoolmates were confirmed with COVID-19 on the same day and were reported to be close contacts. CONCLUSIONS AND RELEVANCE: his cross-sectional study found that nearly all children and youths with COVID-19 in Hong Kong had mild illness. These findings suggest that household transmission was the main source of infection for children and youths with domestic infections and that the risk of being infected at school was small

A prospective controlled double-blind trial of great auricular nerve preservation at parotidectomy

Background: Earlier reports of the advantages of preservating the posterior branches of the great auricular nerve (GAN) at parotidectomy were conflicting. This prospective study was aimed at clarifying the controversy. Methods: Eighty-one patients in a university otolaryngology department were recruited. The posterior branches were preserved whenever initial dissection showed that tumor clearance would not be compromised. Touch-pressure sensation was monitored in predefined territories supplied by the GAN using a Semmes-Weinstein aesthesiometer, preoperatively and postoperatively. Minimal pressure thresholds obtained were compared between the two groups. Results: Preservation of the GAN was achievable in 69% of patients; sensory deficit was transient. With the GAN divided, measurable sensory depression occurred up to 2 years after surgery. The difference is statistically significant. Patients' subjective assessment of numbness also conformed to these trends. Additional time taken for preservation of the GAN was about 10 minutes. Conclusions: The posterior branches should always be preserved if tumor clearance is not compromised. © 2003 Excerpta Medica, Inc. All rights reserved.link_to_subscribed_fulltex
