There are about 3709 clinical studies being (or have been) conducted in Thailand. 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.
Genetic disorders, such as thalassemia, can lead to iron overload and severe adverse health outcomes. In iron-loading thalassemia, iron overload is due to increased iron absorption. Iron accumulates in the body organs causing widespread damage. The standard treatment is iron chelation therapy and/or periodic phlebotomy to remove iron from the body; frequency of phlebotomy or chelation therapy is dependent on how quickly body iron stores accumulate. Polyphenolic compounds are very strong inhibitors of non-heme iron absorption, as they form insoluble complexes with ferrous iron in the gastrointestinal tract that cannot be absorbed. The investigators have recently shown in European subjects with hereditary hemochromatosis (another iron-loading disorder) that our newly-developed natural polyphenol supplement (PPS) that is rich in polyphenols, when taken with iron-rich meals or with an iron-fortified drink, reduces iron absorption by ~40%. Decreasing non-heme iron absorption in adults with iron-loading thalassemia could potentially lead to an extension of the time period between phlebotomies or chelation therapies, and therefore an improved quality of life. Therefore, in this stable iron isotope study, the investigators will study the effect the natural PPS on oral iron absorption from an iron-rich test meal or iron-fortified drink in Thai adults with iron-loading thalassemia.
Liver cancer, specifically cholangiocarcinoma (CCA), is very common in different areas in Thailand. Many factors make this cancer more common, such as liver fluke infection, older age, eating raw fish, family history of cancer, alcohol intake, taking certain medicines (praziquantel), low intake of fresh vegetable, and low education. In 2015, researchers from Khon Kaen University developed the Community-based Health Education and Communication (CHEC) program to prevent liver cancer caused by liver flukes in communities of the Khon Kaen province, Thailand. The main aim of this 5-year research study is to enhance the CHEC program to prevent liver cancer, and test if it is effective in improving the knowledge and behaviours of community residents regarding how to prevent liver cancer. This study will take place in Khon Kaen, Thailand. Other aims are to: 1. Increase understanding in the community that make it difficult to prevent liver cancer, as well as community characteristics that can help prevent liver cancer; 2. Incorporate the program we develop in healthcare to prevent liver cancer in Thailand.
International and national guideline for chronic hepatitis B (HBV) infection treatment recommend initiated antiviral in high HBV viral loads patients with significant liver inflammation and significant liver fibrosis. In Thailand, HBV viral loads and liver elastography are limited available in seconds to tertiary care hospital. Recently, many of simplified scoring system (TREAT-B score, WHO (World Health Organization)-simplified score and REACH-B score) were developed for assessment of antiviral initiation. This study aim to evaluate the performance of simplified score for chronic HBV treatment compare to Thailand and international standard guideline.
Several natural products have been use to promote wound healing and relieve pain. Acmella oleracea has a component that has anesthetic and anti-inflammatory properties. The mucoadhesive film can be improved by drug delivery system due to close contact with the absorption tissue leading to improvement in both local and systemic effects. This study aims to evaluate the effectiveness and safety of mucoadhesive film containing Acmella oleracea extract in healthy subjects. This is a randomised, double-blind (participant and investigator), parallel-controlled clinical trial. In total, approximately 72 subjects will be enrolled into study. Objectives 1. To investigate the potential of skin allergy reaction to mucoadhesive film containing Acmella oleracea extract in healthy subjects 2. To study the duration of mucosal adhesion of mucoadhesive film 3. To study the local anesthetic effect, participant's satisfaction and adverse effect of mucoadhesive film containing Acmella oleracea extract
This study explored the effects of self-compassion intervention on diabetes distress and self-compassion.
The glucose-containing fluid was preferred for maintenance fluid in pediatric surgery to prevent hypoglycemic events. This practice can lead to intraoperative hyperglycemia which can induce osmotic diuresis and consequently dehydration and electrolyte disturbances. As an anesthesiologist, the use of glucose-containing fluid should be reconsidered to avoid these undesirable effects in pediatric surgery. Our study aims to identify an appropriate use of 5% dextrose containing solution during intraoperative period in children (2 age groups: 1-2 vs 3-5 years old) that can prevent glucose and lipid mobilization without causing hypo/hyperglycemia and provide adequate fluid maintenance in the context of hospitals in Thailand
Split-thickness skin graft (STSG) is one of the most common procedures performed in plastic surgery and dermatology. The donor site of skin grafting is expected to heal without scarring. However, hypertrophic scar formation is prevalent among STSG donor sites during scar maturation and has become a significant problem at present. Hypertrophic scar results in aesthetic, physical, functional, and psychological problems, leading to a dramatic impact on patients' quality of life ultimately. There are many current therapeutic approaches for preventing and treating hypertrophic scars; however, they remain clinically unsatisfactory because many treatments have been associated with high recurrent rates, high cost, and side effects. Currently, there are no gold standards for hypertrophic scar therapy. There are many attempts to develop new treatment options for the prevention and management of scarring that are acceptable to both physicians and patients. It has previously been shown that both edible bird's nest (EBN) extract and sericin have effectiveness in reducing scar development. They might be a suitable alternative option for scar prevention and could be used safely. Therefore, the sericin hydrogel sheet impregnated with EBN extract is developed as it is believed that the synergism of these combined compounds would be a great help to prevent the development of scars. This study aims to evaluate the efficacy and safety of sericin hydrogel sheet impregnated with EBN extract for the prevention of scar formation in patients with STSG donor sites.
Women's physiology changes markedly during normal pregnancy. The most distinct alterations occur in the hormonal and cardiovascular systems. There is a dramatic increase in both estrogen and progesterone. Blood volume starts to increase in the first gestational period and reaches a peak in the third trimester. The physiologic ocular changes during pregnancy are mainly the result of hormonal and blood volume increase, and then are usually marked in the third trimester.
Intraocular surgery could induce vitreous degeneration and posterior vitreous detachment (PVD). Vitreomacular interface (VMI) abnormalities usually are caused by abnormal PVD, vitreoschisis and partial-thickness PVD. Furthermore, the PVD could induce the peripheral break. The incidence of peripheral break and epimacular membrane (EMM) after pneumatic retinopexy were 11.7% and 4-11%, respectively. Although multiple intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections induced PVD of 5.6%, but peripheral break was reported as only 0.67%. The most common intraocular surgery is cataract surgery. From the literature review, many methods were used to detect the PVD after phacoemulsification. The former studies used indirect ophthalmoscopy and ocular ultrasound for diagnosis of PVD. The later studies used the optical coherence tomography (OCT) for PVD detection. The OCT device had higher effectiveness in evaluation of the posterior segment, then it can detect post-phacoemulsification PVD more and early than previous studies. Ivastinovic et al demonstrated 59.2% of patients had PVD at 1 month after phacoemulsification, and increased up to 71.4% at 3 months. The incidence of rhegmatogenous retinal detachment (RRD) after phacoemulsification is gradually increased with time. The accumulative risk of RRD was increased from 0.27% at 1 year to 1.27% at 20 years after phacoemulsification.
Tafenoquine was recently approved by regulatory authorities in the USA and Australia. Tafenoquine is an alternative radical curative treatment to primaquine acting against the dormant liver stage of Plasmodium vivax (the hypnozoite). Tafenoquine (an 8-aminoquinoline) has the substantial advantage of single dosing as compared to a 14-day course of primaquine to achieve radical cure. The recommended tafenoquine dose is 300 mg, which was shown to be significantly worse in radical curative efficacy to a total primaquine dose of 3.5 mg/kg in Southeast Asia. The cure rate of tafenoquine 300 mg in Southeast Asian study sites was only 74%. The comparator 3.5 mg/kg total primaquine dose is the standard and most commonly used dose globally, but in Southeast Asia and the Western Pacific, higher doses of primaquine are needed for radical cure. This study aims to determine the optimal dose of tafenoquine in Southeast Asia.
