Filter by:The human intestine is colonized with a complex microbial community and forms a super organism with the human body. Intestinal microorganisms include more than 1,000 kinds of bacterias, and their flora is very complex and functions are very diverse. The intestinal flora affects the body's nutrition, immunity and metabolism through interaction with the human body and the external environment, and is closely related to multiple systems. When the flora structure and function are changed, it will lead to the occurrence of various diseases or increase the risk of disease. In recent years, the role of intestinal microbes in tumorigenesis and development, as well as the role of diagnosis and treatment have been paid more and more attention. Abnormal intestinal flora can not only promote tumorigenesis, but also affect radiochemotherapy and immunotherapy effects. It is worth noting that the huge impact of the intestinal flora on immunotherapy suggests that immune checkpoint inhibitors can maximize the efficacy by protecting the balance and diversity of the intestinal microecology. Therefore, in this study, quantitative analysis of the diversity and abundance of intestinal, urinary tract flora, and urine components before and after adjuvant chemotherapy in patients with gastric and bowel cancer was performed. The link between treatment efficacy and prognosis.
Randomized clinical trial of multimodal prehabilitation in vulnerable patients with colon or rectal cancer prior to surgery.
Improving communication is foundational to improving patient safety. Electronic health records (EHRs) can improve communication, but also introduce unique vulnerabilities. Failure to follow-up abnormal test results (missed results) is a key preventable factor in diagnosis and treatment delays in the VHA and often involves EHR-based communication breakdowns. Effective methods are needed to detect diagnostic delays and intervene appropriately. Manual techniques to detect care delays, such as spontaneous reporting and random chart reviews, have limited effectiveness, due in part to bias and lack of provider awareness of delays. They are also inefficient and cost-prohibitive when applied to large numbers of patients. Diagnostic errors are considered harder to tackle, in part because they are difficult to measure. Rigorous measurement of diagnostic safety is essential and should be prioritized given the increasing amount of electronically available data. To create an effective measurement and learning program researchers must (1) ensure teams know how to take actionable steps on data and have assistance in doing so and (2) prioritize diagnostic safety at the organizational level by securing commitment from local VA leadership and clinical operations personnel. This will ensure that safety measurement will translate into action. The proposed study focuses on creating a novel program to develop and evaluate multifaceted socio-technical tools and strategies to help prevent, detect, mitigate, and ameliorate breakdowns in EHR-based communication that often lead to "missed" test results in the VHA.
The aim of this study is to evaluate the clinical benefit and safety of using an AI device in colonoscopy procedures with the indication of screening or surveillance.
To explore the effect of general anesthesia combined with transversus abdominis plane block (TAPB) and/or rectus sheath block (RSB) on the recovery of patients with gastrointestinal tumor after surgical treatment.
The PHYTOME project (Phytochemicals to reduce nitrite in meat products) is a major European Union (EU) co-funded research project that aims to develop innovative meat products in which the food additive nitrite has been replaced by natural compounds originating from fruits and vegetables. These biologically active compounds, also referred to as phytochemicals, are known to contribute to improved gut health and are added to the meat as natural extracts. In a number of meat products, carefully selected combinations of natural antioxidants and other biologically active compounds occurring in vegetables, fruits and natural extracts such as coffee and tea, will be added during meat processing. Some of these compounds possess an antimicrobial activity allowing them to replace nitrite, whereas others possess a natural red colour that may contribute to the desired appearance of the products. Also, some of these compounds are known to protect colonic cells against damaging effects of cancer causing agents that may be formed in the large intestine after meat consumption. The PHYTOME project will develop new technologies to introduce the natural extracts during processing to different types of meat products. These techniques will guarantee good sensory quality of the product as well as microbiological safety. Once these techniques have been developed and optimized at laboratory scale, the new type of products will be produced on an industrial scale. The health promoting effects of these products will be evaluated in a human dietary intervention study with healthy volunteers. After consumption of a fully controlled diet with either relatively high amounts of the traditional meat products or products produced following the new concept, faeces and colonic material will be collected and investigated for markers of colorectal cancer risk. These investigations will be performed in close collaboration with Research Institutes in the United Kingdom, Belgium, Italy and Greece, and will make use of the newest genomics techniques that are available.
Comparing the complete resection rate and subsequent adenoma recurrence rate at surveillance colonoscopy of 15-40mm laterally spreading adenomas for conventional EMR vs. cold snare EMR.
The purpose of this study is to gather information about the long term health of people who have been prescribed the Cologuard test, which is used for colorectal cancer (CRC) screening.
Inflammation plays an important role in the pathogenesis of peritoneal carcinosis. Patients with elevated levels of different inflammation cytokines show a worse prognosis at the time of diagnosis. In women, ovarian and colon cancer are the main causes of peritoneal carcinosis and a comparison of these two different types of peritoneal invasion have not been conducted yet. We found interesting studying the role of immune response, in particular tumour-associated antigens (TAA) that modulate the metastatic process. We will investigate also mitochondrial defects, such as mutations in mt-DNA, potentially involved in carcinogenesis.
This clinical trial will be conducted as a single-center, open-label, Phase I/2 trial to evaluate the feasibility and safety of Yttrium-90 radioembolization (Y90-RE) in combination with a fixed dose of of immunotherapy (durvalumab - 750 mg) in subjects with liver-predominant, metastatic colorectal cancer (mCRC), which is mismatch repair proficient/microsatellite stable (pMMR/MSS).
