The purpose of this project is to investigate whether a 3-week training program involving music beat (serving as a type of rhythmic auditory stimulation) reduces the severity of bradykinesia and dyskinesia in at-risk individuals and schizophrenia patients. It is hypothesized that the program is effective in reducing the severity of bradykinesia and dyskinesia in at-risk individuals and schizophrenia patients.
The purpose of this study is to evaluate the efficacy of guselkumab treatment in participants with active psoriatic arthritis (PsA) axial disease by assessing reduction in axial symptoms and inflammation.
Restricted range of shoulder motion following ORIF is a potential complication that severely affects the patients' functional outcome and should be actively avoided by means of adequate pain control in addition to early mobilization and physiotherapy. Peripheral nerve blocks, which can be given as a single injection or continuous infusion via an indwelling catheter, are analgesic options to be considered. Interscalene Block (ISB) is the regional analgesia of choice for the shoulder and proximal humerus region. While continuous infusion (aka continuous nerve block) offers the advantage of a longer duration of analgesia compared to a single injection of standard local anaesthetic, it is associated with an inherent risk of catheter displacement, dislodgement, obstruction, and infection. Compared to Standard Bupivacaine (SB), Liposomal Bupivacaine (LB) is a formulation designed to prolong the duration of action to up to 72 hours by slow release of bupivacaine from the multi-vesicular liposomes. Several studies have demonstrated satisfactory analgesic effects of liposomal bupivacaine given as local surgical site infiltration over placebo. However, the effects of single injection of liposomal bupivacaine given via local surgical site infiltration compared to continuous nerve block have been inconsistent. Administrating liposomal bupivacaine directly to peripheral nerve blocks is a potentially effective approach that has not been extensively studied. ISB with single shot liposomal bupivacaine has been shown to provide superior postoperative analgesia compared to ISB with injection of standard bupivacaine or placebo. ISB with liposomal bupivacaine could perhaps prolong and improve postoperative analgesia without the potential problems with continuous nerve blocks. The analgesic effect of ISB with single shot liposomal bupivacaine versus continuous ISB with standard bupivacaine has not been previously investigated. The aim of this study is to compare the analgesic effect of these two analgesic modalities for plate fixation of proximal humerus fractures.
Because of continuous change of the supporting oral tissues, removable dentures can gradually lose retention and stability, resulting in reduced masticatory efficiency. Denture adhesive is a commercially available material used to adhere a denture to the oral mucosa. Our previous review indicated that denture adhesive can improve denture retention, bite force and masticatory performance of complete denture wearers. However, related studies in partial dentures are rare. Therefore, this study aims to investigate the effects of denture adhesives on the masticatory performance and oral health related quality of life of removable partial denture and complete denture wearers. Participants will be identified and recruited from the patient pool of the Prince Philip Dental Hospital (PPDH). Target patients are those who have problems with their existing dentures (for example, dissatisfied denture retention and stability, or reduced chewing efficiency), but do not plan to have new dentures. After sample size calculation, 47 participants are expected to be recruited for this clinical trial. In this study, each participant will be interviewed by a trained interviewer and undergo a clinical examination. Information about the oral condition, denture condition, masticatory performance, oral health related quality of life, socio-demographic and other data will be recorded. Saliva samples will be collected for analysis of oral microorganisms. A commercial copolymer-based cream adhesive (Polident, GlaxoSmithKline, Sussex, UK) is selected as the denture adhesive. Participants will be shown to apply the adhesive following the manufacturer's instructions. The denture is pressed firmly into place, then held firmly as the participant bites down to secure it. Participants will be instructed to apply the adhesive twice daily with an 8-hour interval. Outcome measurements will be taken before application of denture adhesives, 1 week, 4 weeks and 12 weeks after usage of denture adhesives.
COVID-19 has spread rapidly and now affects all over the world. On 11 March 2020, coronavirus disease 2019 (COVID-19) was declared a global pandemic by the World Health Organization (WHO). Most of the infected people will develop mild to moderate illness, for example fever, cough, tiredness and joint pain etc. For some older people, and those with comorbidities like cardiovascular disease, diabetes, chronic respiratory disease, and malignancy are more likely to develop serious illness. Also long-term problems such as fatigue, breathlessness and joint pain experienced by survivors of COVID-19 after discharge from hospital. Some clinical and pharmacological studies have suggested Traditional Chinese Medicine (TCM) has achieved remarkable therapeutic effect for active COVID cases of different severity during SARS epidemic in 2003. Also, some studies shown that using Chinese medicine interventions together with conventional treatment is more effective than using the conventional treatment alone in treating chronic fatigue syndrome. Traditional Chinese Medicine (TCM) has a long history and played an important role in the prevention and treatment of several epidemic diseases. However, there is a lack of clinical study of using TCM to treat the residue symptom of COVID-19 recovered patients. COVID-19 recovered patients will be screened and randomized into TCM group or placebo group for 8 weeks and followed by a post-treatment visits at week 12.
The purpose of the study is to investigate the effect of bright light therapy, myopic defocus, atropine and the combination in myopia control in schoolchildren.
This pilot randomised wait-list controlled trial aims to determine the feasibility, acceptability and preliminary effects of a Family Acceptance and Commitment Therapy-based Eczema Management Programme (FACT-EMP) on the health outcomes of both children patients and their main caregivers over a 3-month post-intervention.
The investigators propose a phase II single-arm study on using stereotactic body radiation therapy in combination with durvalumab for inoperable/unresectable hepatocellular carcinoma. In addition, the investigators will also measure the change in number and intensity of PD-L1-positive circulating tumor cells before and after stereotactic body radiation therapy and durvalumab and evaluate their correlation with treatment response.
Necrotizing enterocolitis (NEC) is a devastating disease that affects the intestine of premature infants and is the most common surgical emergency in newborns. It is estimated that up to 10% of premature babies can suffer from this condition. Despite aggressive medical treatment, surgical intervention is necessary in up half of the cases for bowel necrosis or perforation and these often represent the more severe form of the disease. The advances in neonatal intensive care and surgical knowledge have resulted in improved survival rate in recent years. For NEC patients with severe disease (i.e.) those with intestinal perforation or gangrenous bowel not responding to medical therapy, surgery with resection of diseased segments is the treatment of choice. Traditional surgical approach would be to resect the diseased bowel segment with formation of enterostomy. However, in a few advanced centres, primary anastomosis after the resection of diseased bowel segment is practised. Retrospective reports of the primary anastomosis approach have shown that this is also a viable option with no increased rate of peri-operative morbidity. It also has the advantage of avoiding a second operation for enterostomy closure. Nonetheless, prospective studies comparing the two approaches are lacking. The proposed study will fill up the following knowledge gap on what the best surgical option for NEC at laparotomy is. The findings will help guide our practice for NEC patients in the future in order to provide them with the best possible and evidence-based care. In this study, the investigators hypothesize that neonates with major NEC undergoing primary anastomosis after surgical resection is not inferior to neonates who have enterostomy, in terms of peri-operative morbidities. Aim of the study is to compare the short term and medium term outcomes of NEC patients requiring surgical intervention who either receive primary anastomosis or enterostomy creation.
