There are about 3491 clinical studies being (or have been) conducted in Singapore. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Our study involves the evaluation of a high potency chemical peel in its efficacy and safety profile for the treatment of acne scars. This chemical peel regime is a high potency peel of 70% glycolic acid combined with vitamin C that is purported to provide a good balance between yielding results and patient safety. We aim to evaluate its efficacy and safety profile of a single application. The study design is based on a single group that compares pre- vs post-intervention. 10 patients with atrophic acne scars of skin type I-IV will be recruited. Potential benefits include improvement of post acne scars with a short downtime and risks include post peel hyper pigmentation and scarring. We believe that this treatment will be highly beneficial to patients with post acne scarring. This chemical peel regime has good efficacy and safety profile for the treatment of acne scars.
Our study involves the evaluation of a high potency peel in its efficacy for skin rejuvenation in the treatment of photoaging. This chemical peel regime is a high potency peel 70% glycolic acid combined with vitamin C that is purported to provide a good balance between yielding results and patient safety. AIM We aim to qualitatively evaluate its efficacy and safety profile. Our hypothesis is that a single peel of 70% glycolic acid combined with vitamin C will result in improvement of the features of photoaging with few side effects.
According to World Health Organization (WHO) estimates, more than 200 million people suffer from asthma worldwide and in 2009, the disease had claimed 250,000 lives globally. Autopsy reports suggest 2 phenotypes of severe asthma: one that is characterized by intense airway inflammation with mucus plugging, and the other by severe bronchoconstriction causing respiratory failure in the absence of significant airway inflammation. However, it is not easy to stratify patients according to phenotypes without bronchoscopy. Although severe asthma comprises only 10% of affected individuals, it accounts for more than half of the total healthcare spending on asthma. Inhaled corticosteroids are effective by suppressing production of multiple pro-inflammatory mediators, unfortunately efficacy plateaus. Addition of long acting beta agonist and anti-cholinergic agent to inhaled corticosteroids offers some measure of relief but effective treatment of severe asthma remains an unmet goal, resulting in intensive utilization of healthcare resources. In 2010, the United States Food and Drug Administration (FDA) approved bronchial thermoplasty (BT) as an adjunctive therapy for severe asthma. BT is radiofrequency ablation of airway smooth muscle via bronchoscopy with each patient undergoing three procedures which targets different lobes of the lung 3 weeks apart. Studies have demonstrated improved symptom control allowing discontinuation of oral steroids in some patients as well as reductions in exacerbations, hospitalizations and use of rescue medications. No development of airway strictures or bronchiectasis, and regeneration of normal epithelium after BT has been observed. At present, it remains unclear if BT benefits all asthma phenotypes or if BT has any effect on airway inflammation and remodeling. The hypothesis of this study is that bronchial thermoplasty is likely to benefit all severe asthma phenotypes, and achieves this by exerting an effect on airway inflammation and remodelling. The specific aims of the study are: 1) to better define the asthma phenotype who will benefit from BT by microarray and gene expression profiling; 2) to study effects of BT on airway inflammation; 3) to define its role in the overall asthma management algorithm
i. To determine whether Confocal Laser Endomicroscopy (CLE) with optical biopsy and targeted mucosal biopsy improves the diagnostic yield of gastric IM/IN/CA in high risk populations compared to WLE with standard biopsy protocol. ii. To determine whether CLE with optical biopsy and targeted biopsy, as compared to WLE with standard biopsy, can reduce the number of biopsies needed per patient for detection of gastric IM/IN/carcinoma without the loss of corresponding diagnostic yield. iii. To compare the sensitivity and specificity of CLE with WLE for the detection of gastric IM/IN/CA.
Median sternotomy has been the standard incision for coronary artery bypass grafting (CABG) in patients undergoing surgery for coronary artery disease. Given the increasing risk profile of contemporary cardiac surgery patients, sternal complications are subject to increase concomitantly. Despite advances in many areas of cardiac surgical procedures, innovation in sternal closure technique has been lacking and postoperative complications remain. In this study, the investigators aim to assess the effectiveness of using a novel osteoconductive biologic bone cement (KryptoniteTM, Doctors Research Group Inc.) as an adjunct to conventional sternal closure in post CABG patients having median sternotomy. The outcomes of interest for this study will include: pain, discomfort, lung function, wound healing and analgesic use. The investigators assume that the use of KryptoniteTM will decrease postoperative pain leading to improvement in postoperative lung function. This may also lead to improvement in patient recovery and decrease in postoperative complications. The investigators will undertake a single-blinded randomized, controlled study consisting of patients undergoing elective coronary artery bypass grafting (CABG) randomly assigned to either Group A (usual closure with stainless steel wires) or Group B (usual closure with stainless steel wires plus application of bone cement). Each group will consist of 64 patients in a total of 128 patients. Lung function data using a spirometer will be collected preoperatively and 3rd and 5th postoperative days as well as in outpatient clinic. Pain data will be collected on the 1st to 5th postoperative days.
The overall objective of this study is to investigate in depth the impact of birth weight on the nature of metabolic physiology, body composition and epigenetic differences of the different phenotypes of overweight and obese individuals who are otherwise overtly healthy. We also aim to determine the efficacy of a weight loss intervention on the above mentioned metabolic parameters in these individuals.
The primary aim of this research protocol is to compare if there is a difference in progression free survival between weekly versus 5-day 3 weekly cisplatin based chemotherapy regimen in women with locally advanced cervical cancer. The secondary aims are to compare quality of life assessment of patients and their carers as well as toxicity profiles both acute and late.
