NCT ID: NCT06381310 Recruiting - Clinical trials for Successful Cannulation

Ultrasound-guided Cannulation of Difficult Hemodialysis Arteriovenous Access

Start date: February 26, 2024
Phase: N/A
Study type: Interventional

Patients with ESRD are able to maintain life by undergoing renal replacement therapy, including hemodialysis (HD), peritoneal dialysis (PD) or kidney transplantation. HD continues to be the primary option. Arteriovenous fistula (AVF) and arteriovenous graft (AVG) are the common access sites for hemodialysis (HD) patients. AVF is the best access for dialysis , which is known as the lifeline of hemodialysis patients, but requires 6 to 8 weeks to maturate. Long-term use of an AVF for dialysis requires the ability of the dialysis staff to cannulate it successfully with large-bore needles thrice weekly. With increasing AVF prevalence as well as aging and more obese populations in the developed world, increasing numbers of difficult-to-cannulate AVFs are being encountered in practice. Traditionally, after maturation, cannulation of new AVF/AVG was performed by trained renal nurses through physical examination, namely listening to bruits and feeling for thrills to guide needle placement, known as "blind" cannulatio. However, physical examination is not reliable for first and difficult access cannulation (e.g., small or partial stenosis, deep-seated AVF/AVG, presence of clots, after multiple failed attempts with hematoma /swelling, and/or immature access with small vessel caliber), rendered higher rate of cannulation failure and lower AVF and AVG survival. Unfortunately, cannulation failure result in access damage, vessel intimal lining damage leading to stenosis, thrombosis, or aneurysm formation contributing to AVF failure, treatment delay and increased requirement for central venous access devices (CVAD). Patients with early AVF failure have much higher mortality risk, particularly if they are older and female. Van Loon et al. revealed that up to 90% of the first cannulation had complications (i.e., infiltration including hematoma formation and missed cannulation). With a high rate of AVF maturation failure (38-60%) in general, cannulation failure may be avoidable if a more in-depth assessment was done before the attempt. Ultrasound (US) guided cannulation effective in identifying access location and patency. Roshan et al. reported a case study on bedside ultrasonography for AVF cannulation. The study showed decreased cannulation failure, vessel wall damage, thrombosis, and hematoma formation risks also reduced missed cannulation and increased staff confidence in performing cannulation. Therefore, this study aims to explore the effects of ultrasound technology on arteriovenous access successful cannulation for patients with end-stage kidney disease to provide reliable research integration evidence as the basis for future clinical care.

NCT ID: NCT06380933 Completed - Sleep Quality Clinical Trials

NCT ID: NCT06379256 Not yet recruiting - Clinical trials for Hepatocellular Carcinoma

Evaluation of Immune Responses and Outcomes in Patients With Hepatocellular Carcinoma Undergoing Radiotherapy

Start date: April 26, 2024
Phase:
Study type: Observational

Radiation therapy (RT) is a highly effective modality for managing localized solid tumors and has become a fundamental component of treating unresectable hepatocellular carcinoma (HCC). Our previous preclinical investigation (Hsieh et al., Science Immunology 2022) revealed that RT can initiate immunogenic cell death and facilitate the cross-presentation of tumor antigens by antigen-presenting cells, thereby augmenting systemic anti-tumor T cell responses in murine tumor models. However, this immune response subsequent to irradiation has not been comprehensively evaluated in clinical trials involving HCC patients. Given that RT represents a standard therapeutic approach for unresectable HCC, our ongoing phase II non-randomized trial aims to prospectively assess immunological responses and dose-volumetric parameters, while identifying predictors of clinical outcomes in patients undergoing definitive RT for HCC.

NCT ID: NCT06376266 Recruiting - Sarcopenia Clinical Trials

Assessment of the Intervention Effectiveness of Branched-chain Amino Acids(BCAA) Combined With Medium-chain Fatty Acid(MCFA) Products in Sarcopenia Among Middle-aged and Elderly Individuals

Start date: October 1, 2023
Phase: N/A
Study type: Interventional

Taiwan entered an aging society in 2018 and is expected to transition into a super-aged society by 2025. With the increasing elderly population, age-related diseases pose urgent challenges to modern society. According to the Ministry of Health and Welfare's National Health Statistics in 2018, the prevalence of sarcopenia in Taiwan among individuals aged 65 and older is 23.6% for males and 18.6% for females. Sarcopenia, characterized by the loss of skeletal muscle mass due to aging, coupled with decreased muscle strength and/or reduced physical performance, poses a significant risk for disability, decreased quality of life, and increased mortality. Existing research indicates that appropriate nutrition and exercise can slow the onset of sarcopenia and even increase muscle mass to reverse its effects. This study is an interventional clinical trial recruiting middle-aged and elderly patients with sarcopenia or pre-sarcopenia. The intervention involves a combination of branched-chain amino acids and medium-chain triglyceride products, and the study aims to assess the effectiveness of this intervention for sarcopenia in middle-aged and elderly individuals.

NCT ID: NCT06373887 Recruiting - Weight Loss Clinical Trials

The Efficacy of Weight-loss Diet Decision-making Based on Initial Gut Metabolic Modules (GMMs)

Start date: April 10, 2024
Phase: N/A
Study type: Interventional

In recent years, the technology to detect the gut microbiome's function has become increasingly developed. GMMs are tools (GitHub - raeslab/GMMs: A manually curated database of human gut metabolic modules.) for describing metabolic pathways for linking microbial metabolic function to species associated with a single metabolite, helping to analyze the transcriptional characteristics and metabolic functions of each bacterium, and studying their role of the food chain in the ecosystem. According to our previous research, the group with good weight loss response (more than 10% body weight loss in 8 weeks) after low-carb diet intervention has higher Shannon's diversity and carbohydrate degradation activity test by GMMs, implying the deficiency of availability of energy sources may cause more weight changes. Based on the above research, we designed a low-carb diet (rich in monounsaturated fatty acids) and a low-fat diet (whole grains) with the same calories as a means of weight loss. The primary purpose of this study is to evaluate the pre-GMM test for determines the weight loss benefit of the intervention diet. Furthermore, we try to found the possible mechanism of whether metabolites of microbiota (e.g. SCFA) could affect the immune cell change which modulates adipose tissue .

NCT ID: NCT06372171 Recruiting - Nutrition, Healthy Clinical Trials

Effects of Liposomal Encapsulation on Vitamin C Absorption and Metabolism

Start date: April 2024
Phase: N/A
Study type: Interventional

Vitamin C is an important antioxidant in the human body and plays many important roles. It is currently known that vitamin C has the functions of treating scurvy, assisting in collagen synthesis, whitening, and increasing immunity. Smokers, patients with cardiovascular disease, and patients with diabetes may have higher requirements for vitamins due to higher oxidative stress in the body. Liposome coating is a technology commonly used in food processing and medicine to protect active substances, increase absorption or slow release. Currently, vitamin C is commonly available on the market as an additive nutritional supplement in the form of powder packets, tablets, etc. The disadvantages are that vitamin C is relatively unstable, easily destroyed by gastric acid, and maintains blood concentration for a short time. Taking liposome microbial C has been Found to have the potential to increase bioavailability in the human body, it is expected that vitamin C coated with lecithin is relatively stable and can be stabilized in the small intestine without being damaged by gastric acid, while reducing the risk of gastrointestinal discomfort caused by the acidity of vitamin C. According to the revised seventh edition of the Reference Intake of Dietary Nutrients for Chinese People, the upper daily intake of vitamin C (tolerable upper intake levels, UL) for people aged 19 to 70 is 2,000 mg. According to literature, the absorption rate of vitamin C when consuming 30-180 mg per day is about 70-90%; when the daily intake exceeds 1000 mg, the absorption rate will drop to less than 50%. The dose of vitamin C used in this study is more than 1500 mg. The purpose is to explore whether the sustained-release characteristics of liposome coating technology can improve the absorption rate and achieve better bioavailability when consuming high-dose vitamin C powder. It is expected that through the egg The liposome vitamin C powder made of phospholipids increases its maintenance time in the blood, thereby increasing the supplementary effect of vitamin C powder and serving as another supplement option for vitamin C.

NCT ID: NCT06372158 Recruiting - Osteoporosis Clinical Trials

Effects of Liposomal Encapsulation on Calcium Powder Absorption and Metabolism

Start date: April 8, 2024
Phase: N/A
Study type: Interventional

Compared with traditional calcium supplements, liposome calcium can increase the bioavailability of calcium and reduce the waste caused by gastric acid destruction of calcium. This allows calcium to be released slowly in the intestines, reducing the risk of indigestion or other side effects caused by excessive intake at one time. Liposomal calcium can be taken orally directly. It does not need to be dissolved in water before taking like other calcium supplements, making it more convenient to use. Based on the above advantages, liposomal calcium is a relatively safe and easy-to-absorb calcium supplement, suitable for long-term use, and can meet the body's demand for calcium. According to the recommendations of the World Health Organization, the daily calcium intake for adults should be 1000-1300 mg. In Taiwan, the seventh edition of the revised reference intake of dietary nutrients for Chinese people recommends that the daily intake for adults should be 1,000 mg. The calcium dose used in this study was 500 mg. The purpose was to explore whether the sustained-release characteristics of liposome coating technology can improve the absorption rate after consuming calcium powder and achieve better bioavailability. It is expected that microlipids made by lecithin can Lipid calcium powder increases its maintenance time in the blood, thereby increasing the supplementary effect of calcium, and is an alternative to calcium supplements.
