The trial aims to test a novel rehabilitation device for subacute stroke hemiplegic upper limbs based on state-of-the-art non invasive Brain-Computer Interface (BCI) robotic rehabilitation in a clinical setting. The investigators aim to prove the clinical efficacy and safety of BCI therapy over traditional rehabilitation methods.
This is an observational, prospective and pilot study to determine through confocal endomicroscopy diagnostic microscopic features detectable at the gastroesophageal junction of patients with non-erosive gastroesophageal reflux disease. The hypothesis is that minimal mucosal changes occur in non-erosive gastroesophageal reflux disease. Although these minimal changes are not always visible on white-light endoscopy, it is detectable using high-resolution confocal endomicroscopy and these confocal features are diagnostic of non-erosive reflux disease (NERD).
1. To determine the association between LVD and clinico-pathologic variables in archived colorectal cancer and Nasopharyngeal carcinoma specimens 2. To determine the association between VEGF-C,-D expression with COX-2 expression and clinico-pathologic variables in colorectal cancer and Nasopharyngeal carcinoma 3. To determine the effect of celecoxib on lymphangiogenesis in Nasopharyngeal carcinoma Lymphangiogenesis and factors modulating lymphangiogenesis are associated with clinico-pathological outcome in Nasopharyngeal carcinoma and colorectal cancer. Celecoxib down-regulates lymphangiogenesis Archival colorectal cancer and Nasopharyngeal carcinoma tumor specimens will be obtained from the Department of Pathology. To determine the effect of celecoxib on lymphangiogenesis in Nasopharyngeal carcinoma, the investigators intend to analyze archived specimens collected in a previously conducted study. Colorectal tumor and nodal specimens and Nasopharyngeal carcinoma primary will be examined for MVD, LVD and growth factor expression using established haematoxylin and eosin and immunohistochemical techniques. Quantification of LVD and MVD shall be performed by two pathologists blinded to clinico-pathological variables using standardised methods.
The purpose of this study is: 1. To determine the proportion of Asian patients achieving a target area under the curve (AUC) of 20-24 mg.h/L using a pharmacokinetically guided 5-fluorouracil (5-FU) dose 2. To determine the safety and tolerability of dose adjusted 5-FU 3. To correlate 5-FU pharmacokinetics with gene variants associated with the 5-FU pathway and with clinical outcomes Based on Western data, levels of 5-FU are highly variable when doses are based on BSA. A relationship between systemic plasma levels of 5-FU and treatment toxicity and efficacy exists. Whilst pharmacokinetically-guided dose management has been shown to improve 5-FU efficacy and tolerance, there is currently no data in Asian patients using this approach. Using pharmacokinetically guided 5-FU-dose adjustment, the investigators hypothesize the proportion of Asian patients achieving a target AUC of 20-24 mg.h/L is similar to that of Caucasians. METHODS: This is an open, non-randomised single center Phase II study evaluating dose adjusted 5-FU in patients receiving de Gramont, FOLFIRI or mFOLFOX-6 schedules.
This protocol aims to create a tissue bank of breast tumors obtained at the time of diagnosis for the identification of biomarkers for diagnosis, prognostication, and prediction of treatment response in breast cancer. While tissue banks now exist in major hospitals in Singapore to collect tumor specimens at the time of surgery, specimens collected at surgery from patients who had undergone pre-operative treatment represent a post-treatment sample and not a baseline, untreated sample. Such samples are intrinsically different from untreated samples, and have to be analyzed separately from untreated samples. However, they remain valuable samples, particularly if a pre-treatment sample has been obtained, providing paired pre- and post-treatment samples, which could provide valuable information on treatment-related tumor biomarker changes. A tissue bank comprising of samples collected during the diagnostic core biopsy thus represents a valuable supplement to existing tissue banks. Approximately 10-20% of patients diagnosed with non-metastatic breast cancer will require neoadjuvant chemotherapy. In addition, future clinical trials may include 'window-of-opportunity' studies during which biological therapy is administered for a short period (2-3 weeks) while an operable breast cancer patient is awaiting definitive surgery. The majority of early-stage breast cancer patients would be eligible for such trials, allowing the rapid recruitment of breast cancer patients. When coupled with analysis of surrogate markers of response (eg apoptosis, anti-angiogenic effects, etc), these unique clinical trials could provide valuable insights into the biological effects of new therapeutic agents in evaluation.
Aims of Research Proposal: 1. To build a DNA bank in association with a comprehensive database of treatment outcomes and toxicities of cancer patients. 2. To carry out genotyping of potential candidate genes in relation to specific anti-cancer agents and to correlate genotype with treatment outcomes and toxicities. The investigators hypothesize that genetic variations between different individuals and ethnic groups may account for inter-individual and inter-ethnic differences in treatment response and toxicities to anti-cancer therapy. The understanding of the contribution of these genetic variations may help to individualize therapy to optimize treatment outcomes and reduce toxicities. Patients will be recruited from the National University Hospital Cancer Centre. Any individual aged 18 or above who has been diagnosed with cancer is eligible. 20 ml of blood will be collected from each subject for DNA extraction and pharmacogenetics analysis. At the time of recruitment, demographic characteristics, cancer history, and past and present cancer treatment history of the study subject will be collected. The patients' progress will be followed up periodically (approximately every 6 months) through the medical records, and subsequent cancer treatments, progression of cancer, and survival outcome will be updated. Follow-up will occur until death. Important treatment information that will be collected include the drug regimen, drug doses, intent of treatment, aematologic and non-haematologic toxicities, and hospitalization episodes that may be related to treatment. Known functional single nucleotide polymorphisms (SNPs) of drug metabolizing enzymes, transporters and targets of different anti-cancer agents will be characterized. More comprehensive genotyping will be carried out in 'outliers' who experience exceptional toxicity or biological response to identify novel functional SNPs using high throughput sequencing techniques. Correlation will be made between genotype and treatment-related outcomes (tumor response, progression-free survival) and toxicities. For selected patients, lymphoblastoid transformation will be carried out to maintain an infinite supply of DNA.
The aim of this study is to demonstrate that clazosentan, administered as a continuous intravenous infusion at either 5 mg/h or 15 mg/h until Day 14 post aneurysmal subarachnoid hemorrhage (aSAH), reduces the incidence of cerebral vasospasm-related morbidity and all-cause mortality within 6 weeks post-aSAH treated by endovascular coiling. The primary endpoint of the study is the occurrence of cerebral vasospasm-related morbidity, and mortality of all-causes within 6 weeks post-aSAH, defined by at least one of the following: 1. Death (all causes). 2. New cerebral infarct(s) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 3. Delayed ischemic neurological deficit (DIND) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 4. Administration of a valid rescue therapy in the presence of confirmed cerebral vasospasm on angiography (DSA or CTA). An independent Critical Events Committee (CEC) will adjudicate whether or not patients meet the primary endpoint and its individual morbidity components.
