NCT ID: NCT04416061 Completed - COVID Clinical Trials

The Role of a Private Hospital in Hong Kong Amid COVID-19 Pandemic

COVID-19
Start date: May 11, 2020
Phase:
Study type: Observational

Hong Kong public healthcare system is facing tremendous pressure under the COVID-19 pandemic. As the virus spread in Hong Kong, Hong Kong Sanatorium & Hospital (HKSH) is one of the first private hospitals which immediately provide reliable and rapid COVID-19 test -- Reverse Transcription Polymerase Chain Reaction (RT-PCR). Early provision of the RT-PCR screening test for COVID-19 not only facilitates identification of COVID-19 but also contains the spread of the virus in the community and frontline medical staff. Since description of role of private hospital in Hong Kong amid COVID-19 pandemic is lacking, this study will describe COVID-19 screening algorithm and methodology. A retrospective analysis on clinical characteristics, laboratory findings as well as outcome of patients who underwent COVID-19 test in HKSH is also performed.

NCT ID: NCT04413513 Completed - Anxiety Symptoms Clinical Trials

Effect of IATP on Cognitive Functioning in Anxious Older Adults.

Start date: August 13, 2018
Phase: N/A
Study type: Interventional

Older adults with anxiety symptoms was found to be associated with greater risk of dementia. Interventions targeting signs as early as in the pre-symptomatic phase could be most effective in early prevention of dementia. On reviewing the identified non-pharmacological interventions, integrated attention training program (IATP) is proposed to target older adults with anxiety symptoms in Hong Kong.

NCT ID: NCT04409496 Completed - Smoking Cessation Clinical Trials

Chat-based Support for Preventing Smoking Relapse

Start date: June 2, 2020
Phase: N/A
Study type: Interventional

This pilot trial aims to evaluate the effectiveness of chat-based instant messaging support in preventing smoking relapse in recent tobacco abstainers.

NCT ID: NCT04403373 Completed - Clinical trials for Major Depressive Disorder (MDD)

Effectiveness of Walking Exercise in Improving Depression in Older Adults With Major Depressive Disorder, A Pilot Study

Start date: November 1, 2019
Phase: N/A
Study type: Interventional

1. This pilot randomized controlled trial aims at investigating the effects of different intensities of aerobic walking exercise to alleviate depression in older adults with major depressive disorder. Both baseline and post-intervention measurements will be conducted at the Exercise Physiology Laboratory, Division of Kinesiology, School of Public Health, The University of Hong Kong, while the exercise intervention will be conducted outdoors in a small group setting (3-5 participants). 2. Three-time-per-week moderate-intensity (~3.5 METs) or vigorous-intensity (~7 METs) walking exercise will be prescribed to participants in two exercise groups, while the participants in the waitlist group will receive no intervention. The intervention duration is 12 weeks. 3. We will recruit participants from the community in HK. Interested participants will be invited for a semi-structured interview including an assessment on the Beck Depression Inventory and medical history record to confirm eligibility.

NCT ID: NCT04399369 Completed - Dental Caries Clinical Trials

Preventing Caries With Silver Diamine Fluoride

Start date: September 16, 2020
Phase: Phase 2
Study type: Interventional

Background: Early childhood caries (tooth decay, ECC) affected 55% 5-year-old Hong Kong children, and 70% of these children had gross destruction of the upper anterior teeth with negative long-term impacts on health and quality of life. The existing standard of care for prevention of ECC, topical application of 5% sodium fluoride (NaF) varnish, is inadequate. In Hong Kong and other parts of the world, 38% silver diamine fluoride (SDF) solution, applied topically to cavities, is used to arrest ECC. Work published by our research group suggests it likely also has a preventive effect of ECC. Moreover, SDF has been shown to be preventive in tooth decay in permanent teeth. Nevertheless, no pivotal clinical trial has been performed to support a change in usual practice. Aim: This is a Phase II single-centre randomized, double-blind, active-controlled, parallel-group pragmatic trial with two arms to assess the effectiveness of 38% SDF and 5% NaF in preventing new caries lesions in primary anterior teeth. Methods: 688 three-year-old kindergarten children who are healthy will be recruited, stratified by school, and block randomized to receive either 38% SDF (treatment group) or 5% NaF (standard treatment group) therapy on primary upper anterior teeth. This sample size is sufficient for a superiority trial with power at 90%, allowing for a 15% dropout rate. The primary outcome is the number of sound tooth surfaces that become cavitated caries per child at 12-month follow-up. The secondary outcome is the number of carious tooth surfaces developed after baseline that become arrested at 12-month for each child. Dental examinations for the status of caries (active or arrested) will be conducted by the same calibrated examiner. The examiner, children and children's parents will be blind to treatment allocation. Parents will be surveyed to study the children's oral health-related behaviours and socioeconomic backgrounds, which will allow the adjustment for effect modification. Possible results and implications: If the results are as anticipated, it will help change the standard of care for caries prevention. If adopted in Hong Kong, SDF therapy will prevent 20,800 (13% of the 160,000) kindergarten children from having caries developed in their anterior teeth, thus reduce significantly the burden of ECC of the children and related stress of their family. Moreover, the results will be widely available and increase adoption of SDF in other countries to reduce the global burden of ECC among children.

NCT ID: NCT04398888 Completed - Clinical trials for Postprandial Distress Syndrome

Efficacy of a Modified Banxia Xiexin Decoction for the "Wei-Pi" Syndrome (Postprandial Distress Syndrome)

Start date: August 1, 2020
Phase: N/A

Bintrafusp Alfa in Previously Treated Patients With R/M Non-keratinizing NPC

Start date: February 27, 2020
Phase: Phase 2
Study type: Interventional

This would be a phase II prospective single arm mono-institutional study conducted in Queen Mary Hospital (Hong Kong) assessing the efficacy and safety of bintrafusp alfa in previously treated patients with recurrent and metastatic (R/M) non-keratinizing nasopharyngeal carcinoma (NPC).
