Impacts of electronic device use on adolescents' sexual knowledge, attitude and perception during the COVID-19 pandemic: A representative sexuality survey.

Background: COVID-19 pandemic has led to school closure and social distancing measures for infection control. Many young people thus spent more time on electronic devices and the Internet. This study aimed to determine if and how sexual knowledge, perception and behavior as well as sexuality among Hong Kong adolescents were affected as a result.

Evaluating the impact and cost-effectiveness of chlamydia management strategies in Hong Kong: A modeling study.

Objectives: To illustrate the epidemiologic and cost-effectiveness impact of shifting the focus from population-based screening toward a targeted management approach for genital chlamydia infection.

Design: Modeling study, implementing an individual-based, stochastic, dynamic network model.

Setting: Hong Kong.

Preferences for chlamydia testing and management in Hong Kong: a discrete choice experiment.

Objectives: As most chlamydia cases are asymptomatic, regular testing and timely management may be necessary for control. We aimed to determine the preferences of people living in Hong Kong for chlamydia testing and management services.

Methods: An online panel of sexually active individuals living in Hong Kong completed the survey with two discrete choice experiments (DCEs).

Baseline knowledge and receptiveness to genetic testing for hereditary breast and ovarian cancer syndromes in Chinese high-risk females.

Limited studies have examined the pre-counselling knowledge and attitudes of high-risk women on hereditary breast and ovarian cancer (HBOC) syndromes genetic screening in Asia Pacific regions, particularly among Chinese. After controlling cost, an intrinsic barrier to undertake such screening, comprehensive understanding of the baseline characteristics of this cohort towards HBOC genetic counselling and testing service (GT) could be sought. This study aimed at exploring the baseline knowledge, possible motivators, barriers, and decisional factors of undertaking such service.

Fighting against COVID-19: preparedness and implications on clinical practice in primary care in Shenzhen, China.

Background: The new coronavirus pneumonia (NCP) caused by COVID-19 has affected more than 46 million people worldwide. In China, primary care has played a vital role during the COVID-19 outbreak, and it is important to examine the challenges faced by general practitioners (GPs). This study investigated the roles, preparedness and training needs of GPs in China in managing the NCP outbreak.

Effects of REM sleep during a daytime nap on emotional perception in individuals with and without depression.

Background: It has been theoretically proposed that alteration in sleep physiology may contribute to the development of biased emotional processing featured in depression. The current study investigated the role of sleep and especially REM in modulating perception of emotional faces in depressed versus non-depressed individuals using a napping paradigm.

Methods: Forty-six individuals with major depressive disorder and 66 age- and education-matched healthy controls completed an emotional face perception task before and after random assignment to one of the three intention-to-treat (ITT) conditions, namely 30-min-nap, 90-min-nap and wake.

Attitudes and compliance of clinical management after genetic testing for hereditary breast and ovarian cancer among high-risk Southern Chinese females with breast cancer history.

Western studies have shown that the uptake rates of surveillance and prophylaxis may vary among BRCA mutation carriers between ethnicities. The present study is the first to investigate the behavioural impact and subjective attitudes in Southern Chinese high-risk families who had undergone BRCA1 and BRCA2 genetic testing up to 2.5 years post-testing.
