Young children with backward positioned lower jaw/chin will be recruited to have an upper jaw expansion appliance. Previous research showed that the use of similar appliances can lead to lower jaw forward growth. 60 young children aged 9-11 will be recruited to have either active or non-active Wilson type upper arch expansion appliance. Patients will have special x-ray (Cone Beam computed tomography) before and after treatment (after 9 months) of starting the treatment. After participation, routine orthodontic treatment will be continued.
In a small group of people gluten, a storage protein commonly in wheat and other grains, can cause gut inflammation and symptoms like diarrhea and abdominal pain. Gluten-related disorders include celiac disease (CD) and non-celiac gluten sensitivity (NCGS) and are treated by starting a gluten free diet (GFD). Patients with CD and NCGS also more commonly experience esophageal reflux and damage to the lining of the esophagus. A potential consequence of long-standing heartburn is Barrett's esophagus (BE), a major risk factor for cancer of the esophagus. This study aims to investigate the mechanism that leads to reflux and BE in those with gluten related disorders, and to assess if a GFD is beneficial. We will study the upper gut function and reflux activity in patients with BE both with and without a GRD disorder. Testing will occur before and after a gluten free diet is instituted. The results will help inform health care providers and patients about the connection between gluten-related disorders, reflux, BE, and the role of GFD.

Introduction A Hong Kong study found that more than half of the chronic kidney disease (CKD) patients declined peritoneal dialysis (PD) and preferred receiving palliative care, although PD is vital for early preservation of residual kidney functions. Decision-making was found to be influenced by feelings of hopelessness, leading to underestimation and the pursuit of a successful plan of action. Cumulative evidences revealed that hope is a factor that heightens positive expectations in patients, and could lead to consideration of wider alternatives and thorough decision making. Aim The aim of this study is to examine the effectiveness of a brief hope intervention in reducing the decisional conflict and improving the quality of life of CKD patients who have to plan for receiving dialysis therapy. If patients' quality of decision-making could be improved, timely initiation dialysis and less decisional regret is expected. Method This study is a single-blinded randomised controlled trial. On completion of the baseline assessment and the screening procedure, eligible participants will be randomly assigned in equal number into either the experimental group (education programme plus a brief hope intervention) or the control group (education programme) using sets of computer-generated random numbers. Patients attending the outpatient renal clinic of a regional hospital in HK will be approached. Stage 5 CKD patients (GRF equal to or less than 15) who are planned to receive dialysis therapy or palliative care will be invited to join the study. Taking into consideration of attrition and the health status of the palliative care patients, it was appropriate to sign up 36 participants per arm, correlation alpha value 0.6, 0.5 effect size with a power of 0.70. There are four waves of data collection, which will be done before the commencement of the intervention (T1), immediately post-intervention (T2) and one month (T3) and three months (T4) after the completion of programme. Primary Outcomes include the assessing the patients' decisional conflict, strength of preference, on their choice of treatment modalities between peritoneal dialysis and palliative care, and health resources utilization. Secondary outcomes measure hope level change and quality of life. Sociodemographic and socioeconomic information will be collected. Two open-ended questions will be used to explore the perceived impact and benefits of the intervention.
This study will evaluate the efficacy and safety of posterior scleral reinforcement on controlling myopia progression, including change in refraction, axial elongation as well as sight-threatening complications, in adults with high myopia. Half the adults will receive posterior scleral reinforcement, while the other half will receive no surgerical treatment.
The purpose of this study is to investigate the change of cholesterol efflux capacity in patients with coronary artery disease treated with secondary prevention drugs, and the correlation with the prognosis.
This is a randomised trial in which healthy volunteers, men and women aged 50-75 years from the general community are randomized into one of three arms: participants will be provided with 50 gm extra virgin coconut oil, or 50 grams butter or 50 extra virgin olive oil to be eaten daily for a month. The food will be provided in the form of processed cheese to mask participants. The key outcome is blood low density lipoprotein cholesterol concentrations and secondary outcomes blood lipid profile (total cholesterol, high density lipoprotein cholesterol, triglycerides) and anthropometric measures: weight and waist circumference. This trial is powered to detect a difference of 0.5 mmol/L LDL-cholesterol difference between the trial arms.
