Active clinical trials for "Colorectal Neoplasms"

Colorectal cancer is among the top three types of cancer that are most common and causes death worldwide.Nutritional support is widely used in elective colorectal surgery patients, as nutritional status is an important factor affecting clinical outcomes. European Society for Clinical Nutrition and Metabolism (ESPEN, 2016) emphasizes that nutritional supplementation with compounds such as amino acids, arginine, glutamine, and fish oil (omega 3) improves postoperative recovery. Glutamine; it becomes an essential amino acid under stress. It is an energy substrate for cells such as intestinal mucosal cells and lymphocytes, a material for glutathione synthesis, and a potent antioxidant, which also increases heat shock protein expression. In stressful conditions, arginine is the primary fuel source for T cells and is required for nitric oxide synthesis; therefore, it helps maintain immune function. Omega 3; It plays a role in the treatment of inflammation and improves wound healing. In addition, EPA and DHA increase the immune response by improving lymphocyte function. RNA; They are essential for maturation, proliferation, and function in nearly all biochemical processes, in rapidly proliferating cells such as T cells. studies have shown that immunonutrition (IMN) formulas enriched with biologically active compounds may be more effective in reducing infection complications and shortening postoperative hospital stays. This study aimed to investigate the additional effects of perioperative compared with preoperative immunonutrition on anthropometric, nutritional, and biochemical parameters, complications, and the length of hospital stay in patients with colorectal cancer.

The study explored the effects of short-term structured psychological care on the level of postoperative psychological resilience, stigma, anxiety and depression in patients with colorectal cancer colostomy.

The aim of this study was to compare the effects of expiratory muscle training (EMT) and incentive spirometry (IS) in addition to conventional pulmonary rehabilitation after colorectal surgery. Twenty-four individuals (13 male) undergoing colorectal surgery were included. They were randomly divided into two groups. In addition to conventional chest physiotherapy, group 1 was performed EMT (n=12), group 2 was performed deep breathing exercises with incentive spirometry (IS) in postoperative period. Respiratory muscle strength, functional capacity, levels of movement and independence, and postoperative pulmonary complications (PPC) were evaluated. Length of stay in hospital (LOS) was recorded.

GERICO is a randomized, controlled prospective trial. The aim is to investigate if frail, elderly patients with stage II-IV colorectal cancer, will profit from full comprehensive geriatric assessment and intervention before and during treatment with chemotherapy. The hypotheses are: Optimizing the health conditions and functional status of frail elderly patients who suffers from stage II-IV colorectal cancer, with geriatric intervention will lead to a higher grade of completing the planned chemotherapy and at higher dose intensity. This will also result in a higher overall survival and improve quality of life.

There is a critical need for physical activity interventions in colorectal cancer (CRC). The investigators have developed a digital health physical activity intervention, Smart Pace, which includes a wearable tracker (Fitbit) and text messaging and aims to have patients build up to 150 min/wk of moderate activity. In this study, the investigators propose to expand and improve Smart Pace, including: 1) enrolling patients during chemotherapy; 2) tailoring text messages to individual preferences and treatment timing; and 3) adding resources to support home-based exercise. The study is a 12-week pilot randomized controlled trial (RCT) to evaluate the feasibility of this novel digital health physical activity intervention among 48 CRC patients on chemotherapy. The specific aims are to: 1) Determine the feasibility of the intervention via adherence and attrition, and determine the acceptability of the intervention via questionnaires and semi-structured interviews . 2) Estimate the effect of the intervention vs. usual care on physical activity, QOL, and symptoms at 12-weeks . And 3) Explore the impact of the intervention vs. usual care on fitness, weight, waist circumference, and blood pressure at 12-weeks.

Fats and oils play important roles in maintaining human nutrition and health through providing energy, essential fatty acids, and acting as modulators of many biological processes (signal transduction, immunity and inflammation). Due to differences in the fatty acid composition and content of antioxidants of individual cooking oils, the degree of oxidative and thermolytic reactions may vary oil by oil. It is lack of human feeding study to investigate the molecular mechanisms on how and which deep-fried oil exerts its adverse effects. The investigators are also lack of biomarkers for monitoring deep-fried oil exposure. Therefore, the purpose of this study is to compare how human body responds differently to several popular uncooked and deep-fried oils with varied fatty acid compositions with respect of oxylipin profile, inflammatory markers, non-targeted metabolomics, and transcriptomics. The investigators will recruit 20 volunteers, provided them once a week the milk shakes prepared from 60g of olive oil, soybean oil, palm oil, camellia oil, tallow (butter), and deep-fried oils of the last 4, respectively; in comparison with a no-fat milk shake control. The experiments lasted for 10 weeks.。Each time; serum, plasma, whole blood and urine samples were collected at baseline, after 2 hours, and after 4 hours. The investigators anticipate to find biomarker(s) for deep-frying, and contribute to the understanding of molecular mechanisms on how deep-fried oils exert adverse effects toward health through integrative omics or so-called system biology approaches.

Pneumoperitoneum, the use of carbon dioxide, presents some disadvantages, including a risk of hypercarbia and respiratory acidosis during surgery in the respiratory system, and of an increased mean arterial pressure and systemic vascular resistance due to sympathetic excitation in the cardiovascular system. 10~15 mmHg intra-abdominal pressure is required in order to achieve a pneumoperitoneum, and increased abdominal pressure following a pneumoperitoneum causes hemodynamic changes leading to a reduced cardiac function by increasing the left ventricular end systolic wall stress and the right and left ventricular filling pressure, while decreasing the stroke volume and cardiac index. The author compared the intra-abdominal pressure necessary to achieve a pneumoperitoneum under deep muscle relaxation and medium muscle relaxation in ten patients undergoing laparoscopic surgery for colorectal cancer as part of preliminary research. The results showed that deep muscle relaxation, compared to medium muscle relaxation, was able to lower the intra-abdominal pressure by an average of 5.6 mmHg (13.2 ± 0.8 vs 7.6 ± 1.1) and the inspiratory pressure by an average of 8. Above all, even after lowering the intra-abdominal pressure with deep muscle relaxation, the surgeon was able to maintain a view almost identical to the one afforded by medium muscle relaxation. However, up until now, no reports have clearly indicated the change in pneumoperitoneum pressure, the patient's hemodynamic change, post-operative recovery, and surgical prognosis depending on the depth of muscle relaxation.Against this background, this study aims to identify the degree to which intra-abdominal pressure in laparoscopic colorectal surgery can be reduced by deep muscle relaxation, and the corresponding advantages this method presents in terms of physiological changes such as hemodynamic and respiratory system changes. In addition, the study intends to examine the difference between deep muscle relaxation and medium muscle relaxation in terms of surgical prognosis, including their effects on post-operative pain and on the patient's recovery of intestinal mobility.

Background: Patients who undergo laparoscopic surgical resection of colorectal cancer may experience various post-operative symptoms (e.g., pain, nausea and vomiting, and anxiety) and limitation of daily activities (e.g., walking capacity). There is also a risk of post-operative complications and a prolonged hospital stay due to complications. Patients who underwent surgical resection may have experienced chronic pain, anxiety/depression, or diminished quality of life. The physical, psychological, and functional aspects of patients' disorders imply the necessity of multidisciplinary care, including complementary or traditional medicines such as acupuncture. This study aims to assess whether acupuncture treatment, combined with an enhanced recovery program after surgery in an inpatient care setting is effective than only an enhanced recovery program after surgery. Objective: To assess the effectiveness and safety of acupuncture combined with an enhanced recovery program after surgery to reduce postoperative symptoms and improve functional recovery and the patients' quality of life.

The purpose of this study is to assess the impact of physician's counseling on participation and utilization of sedation in a primary colonoscopy-based colorectal cancer (CRC) screening program

This is a monocentric study in 2 steps: A safety part to assess the feasibility of using Xenon in association with a thoracic epidural analgesia (TEA) with a sequential recruitment of 3, 6 or 9 patients according to predefined safety rules. The second part will randomly allocated patients (1:1) to receive TEA+Xenon or TEA+Desflurane. 28 patients will be enrolled and followed over 45 days.
