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.
The purpose of this study is to study the safety and efficacy of pooled buffy-coat derived platelets which had been frozen with dimethyl sulphoxide (DMSO), in the prevention of bleeding for patients with hypoproliferaitve thrombocytopenia. These platelets are hereafter referred to as cryopreserved platelets. Patients who have severely low platelet count due to impaired bone marrow function from chemotherapy or certain haematological conditions may need platelet transfusion to prevent spontaneous bleeding. Currently, platelets are stored in liquid form, and must be used within five to seven days of collection. In this study, DMSO is used to preserve platelets during freezing so that they can be stored for longer than five to seven days. Investigators hope to learn if thawed cryopreserved platelets are functional and safe for transfusion in humans.
A case series was built after review of available literature by searching four databases (PubMed, Embase, Medline and Cochrane Library) for observational studies or case reports on routine prophylactic TCT for MEN-1 and the development of thymic carcinoids.
This study is designed to evaluate the preliminary effectiveness and safety of a digitally based multidomain intervention in patients with MCI. In addition, a portion of cognitively normal subjects and caregivers of patients with MCI will also be recruited as an exploratory cohort. We hope that the digital platform will improve the overall cognition and quality of life in patients with MCI.
The side effects following post surgical neck dissection treatment for tumours in the head and neck (HN) region are weakness of the shoulder and neck muscles, numbness and reduced sensation around the neck and shoulder region and a general impact on the participant's overall fitness. While survival has been emphasized as an important outcome, recovery of treatment-related morbidity and return to pre-treatment quality of life (QOL) for participants after cancer treatment is equally important. Sternocleidomastoid (SCM) muscle functions to turn the head to the left or right. In particular while performing neck dissections, SCM dissection is a common step. The side effects of SCM dissection is a stiff neck or reduced neck movements. To objectively measure the outcome of the SCM muscle function, it is necessary to determine what is the normal range of motion in healthy subjects turning to the left and right to look at objects in a specific location or Point-of gaze (POG) procedure, as well as the Electromyography (EMG) of the SCM during the movement. In this normative study, 20 healthy subjects will be recruited to perform this POG assessment as well as EMG and Elastography (ETG) testing of the SCM on the left and right side. Outcome measures will include 1. neck range of motion for flexion, side flexion and rotation 2. EMG activation patterns for SCM 2) muscle thickness & stiffness (as determined by grey scale ultrasound (US) and ETG, respectively) of the SCM The investigators hypothesize that there will not be any significant differences of POG, EMG and ETG measurements between the left and right side of the SCM in healthy subjects.
Aberration of glycosylation is a hallmark of cancer cells, and plays an important role in oncogenesis and cancer progression, including metastasis. One of the markers of aberrant glycosylation (O-linked) is the binding of the lectin Helix pomatia agglutinin (HPA), which has been demonstrated in a wide range of human cancers, especially in tumours with a more aggressive phenotype. Data on the role of HPA within follicular neoplasms of the thyroid gland are currently lacking, therefore we sought to investigate possible changes in cell surface glycosylation associated with this type of neoplasms.
Beta-cryptoxanthin (BCX) is a naturally occurring member of the carotenoid family, found in a wide range of fruits and vegetables. The unique biological functions of BCX have not been well-established, although BCX, like other members of the carotenoids have antioxidant functions. BCX, may also serve as a precursor of Vitamin A. Vitamin A has a wide range of functions including maintain immunity, vision, growth and development. Whilst not specific for BCX, epidemiological studies indicate that dietary intake of carotenoids may be of benefit in maintaining cognitive health and reducing stress via its antioxidant, anti-inflammatory and immunomodulatory properties. This pilot study aims to establish the relationship between supplemental dose and circulating concentrations of BCX and related carotenoids in circulation. Results obtained from this study will provide greater insight of bioavailability and carotenoid metabolism, necessary for larger supplementation in selected target populations.
Oral cancer (including the lip) alone, with 300.373 cases worldwide in 2012, is the predominant head and neck squamous cell carcinoma. With an incidence of 6.5 cases per 100.000, south - east asia has the highest incidence worldwide. Many of these cases do present at a locally advanced stage, which often requires combined modality treatment that includes extensive surgery to the primary site and neck and flap reconstruction. This is often followed by either adjuvant radiation or chemo-radiotherapy. This treatment can come with a significant morbidity affecting the self-care ability of the patients as well as impact the quality of life(QOL) (3,4).At the SingHealth Duke - NUS Head and Neck Centre 340 complex cases of head and neck cancer (HNC) involving flap reconstructions and extensive resections have been operated in 2014 alone. Almost all of these patients need further adjuvant treatment (radiotherapy and/or chemotherapy). Side-effects following such treatments, Significant number of patients underwent subsequent adjuvant treatment. The adjuvant treatment and surgery may render these patients weakness of the shoulder and neck muscles, numbness and reduced sensation around the neck and shoulder region and a general impact on the patient's fitness. While survival remains the most important outcome in oncologic treatment, recovery of treatment related morbidity and return to pre-treatment QOL for patients after cancer treatment is equally important. The aims of this study is to evaluate the impact of surgical and adjuvant treatment on physical functions and QOL of the patients. By measuring the impact of extensive treatments for head and neck malignancies on the fitness and QOL of these patients, the team aims to identify the risk factors that necessitate a more aggressive rehabilitation. This is to date the first prospective study investigating the impact of multimodality treatment on fitness and QOL in HNC patients in a structured and predefined manner. Ultrasound (US) elastography will be used to assess muscle and soft tissue stiffness and elasticity and correlate these with functional outcome measurements. Elastography has been previously described as a useful tool to assess stiffness of the neck soft tissues and muscles, however no study thus far has correlated these findings with functional measurements. Hence this trial aims to establish the following: 1. Due to the limited available data: to quantify and qualify the impact of surgery as well as adjuvant treatment on the fitness, physical function of the neck and shoulder & QOL of HNC patients 2. To establish a workflow and assessment protocol for a subsequent larger prospective clinical trial 3. To identify performance markers in these patients, that allow a more targeted rehabilitation process 4. Many patients post head and neck treatment are economically compromised since they are unable to return to mainstream work and there exists a significant unemployment rate. The understanding we gain through objective analysis apart from targeted treatment for every individual patient, in the future this study hopes to address and improve the economic impact to the individual and probably reduce the health care burden.
Colorectal cancer (CRC) is a leading cause of cancer-related morbidity and mortality worldwide, with rates of CRC predicted to increase. Colonoscopy is currently the gold standard of screening for CRC. Artificial intelligence (AI) is seen as a solution to bridge this gap in adenoma detection, which is a quality indicator in colonoscopy. AI systems utilize deep neural networks to enable computer-aided detection (CADe) and computer-aided classification (CADx). CADe is concerned with the detection of polyps during colonoscopy, which in turn is postulated to help decrease the adenoma miss-rate. In contrast, CADx deals with the interpretation of polyp appearance during colonoscopy to determine the predicted histology. Prediction of polyp histology is crucial in helping Clinicians decide on a "resect and discard" or "diagnose and leave strategy". It is also useful for the Clinician to be aware of the predicted histology of a colorectal polyp in determining the appropriate method of resection in terms of safety and efficacy. While CADe has been studied extensively in randomized controlled trials, there is a lack of prospective data validating the use of CADx in a clinical setting to predict polyp histology. The investigators plan to conduct a prospective, multi-centre clinical trial to validate the accuracy of CADx support for prediction of polyp histology in real-time colonoscopy.
The purpose of this study is to establish the efficacy, safety, and tolerability of remibrutinib (LOU064) in adult participants suffering from chronic spontaneous urticaria (CSU) inadequately controlled by H1-antihistamines in comparison to placebo.
Umbilical vein catheters (UVC) are commonly inserted in newborns especially neonates admitted to the Neonatal Intensive Care Unit (NICU).These catheters are used since 1959. It is a suitable method for parenteral nutrition access and medications administration. Despite the benefits of the UVC, its potential complications must be considered. Thus, it is vital to determine the appropriate penetration length of the UVC.
