Filter by:Dr. Rogers' long-term goal is to better understand the etiology of an early-onset colorectal (CRC) diagnosis and to improve long-term survivorship and quality of life for early-onset CRC (EOCRC) survivors globally by studying the burdens accompanying this condition. The goal of this study is to better understand the reasons why people under age 50 in Utah and Wisconsin are being diagnosed with CRC. As a first step, the researchers identified the specific places in Utah and Wisconsin where diagnoses of CRC among younger people are increasing the most. Next, they conducted 1-hour recorded Zoom interviews over phone and/or video with 27 people across the United States diagnosed with CRC when they were under age 50. Thirdly, the researchers plan to create and test a program that will raise the awareness of residents in Utah and Wisconsin of the increasing risk of CRC among residents of the state who are aged under 50. This study is unique as CRC survivors are key to helping drive the study forward.
Aerobic exercise is associated with many benefits in patients with cancer treatments. Among these, the reduction of cancer-related fatigue (CRF) is one of the best demonstrated. Besides, several animal models have shown a marked reduction in tumor growth with aerobic exercise, sometimes by more than 60%. As the level of physical activity is convincingly associated with a reduction in the risk of cancer or recurrences, this suggests that aerobic exercise may represent a central therapeutic approach during treatment, both against CRF and for its potential anti-tumor effect. Both benefits have been suggested to be based on the immunostimulatory and anti-inflammatory effects of exercise. Indeed, systemic inflammatory activity seems to play a central role in the etiology of CRF during cancer treatments, among other things by stimulating the neuro-inflammatory activity of the central nervous system. Also, regarding the anti-tumor effect of exercise, animal models show that this benefit is partly explained by an increase in the activity of immune cells called natural killers (Natural Killer; NK) in tumor tissue and a reduction in the activity of regulatory T cells, the latter having an immunosuppressive effect. However, in humans, the results vary. While some improvement in NK cell activity has been reported in response to aerobic training in breast cancer survivors, others have seen no effect on the immune profile of patients and survivors. On the other hand, some authors report an improvement in the inflammatory profile with training, while others report little or no effect, as well as weak associations with the perception of fatigue. Although these results seem to discredit the hypothesis of immune and inflammatory regulation of exercise in humans, these studies have all looked at the effect of several weeks of training on the inflammatory and immune profile on an empty stomach and rest. However, several results from the field of exercise immunology convincingly show that the anti-inflammatory effect, as well as the immunostimulating effect of aerobic exercise (including the anti-tumor activity of NK cells) are mainly acute and transient, ie. in the hours following the end of the effort. Furthermore, certain results suggest that in the context of chemotherapy treatments, cyclical treatment by nature, the peaks of fatigue are also acute (i.e. in the days following the treatment) and parallel to peaks of inflammatory activity. Considering these results, it is therefore plausible to assume that the effect of aerobic exercise on suppressing tumor growth and reducing CRF results rather than the repetition of this acute response at each exercise session. In this case, the prescription of aerobic exercise preceding a session of chemotherapy could potentially represent an interesting therapeutic modality, allowing both the reduction of the CRF associated with this treatment, as well as a better response to the treatment. Besides, as this acute response seems to be highly dependent on the intensity of the effort, high-intensity interval training (HIIT) could be a particularly interesting approach in this context, because it does not require that the high intensity or long-lasting exercise. However, considering the immunosuppressive and pro-inflammatory effects of chemotherapy, the extent of the acute response to exercise may not allow this type of therapeutic use to be considered in this population. To date, no study has attempted to characterize the acute immune and inflammatory response following aerobic exercise in patients currently undergoing chemotherapy treatments.
This is a two stage nested case-control study to construct the hologram plane , explore biomarkers and screening original drugs of metastatic colorectal cancer.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been identified as the cause of the Coronavirus disease 19 (COVID-19), which was initially reported in December 2019 in China and has since rapidly spread worldwide. Since then, the COVID-19 pandemic has caused a detrimental effect of the national health care system, causing a drastic reduction of the screening programs for colorectal cancer and requiring the redistribution of the hospital resources from elective surgery to the care of patients with SARS-Cov_2 infection requiring admission.
Anastomotic leakage (AL) is one of the major complications after gastrointestinal surgery. Compromised tissue perfusion at the anastomosis site increases the risk of AL. Indocyanine green (ICG) combined with fluorescent near infrared imaging has proven to be a feasible and reproducible application for real-time intraoperative quantification of the tissue perfusion and cohort studies showed reduced leakage rate. Unfortunately, these studies were not randomized. Therefore, we propose a nationwide randomized controlled trial to identify the value of ICG for AL in colorectal anastomosis.
This is a 3-arm randomized trial aimed at increasing rates of participation in colorectal cancer (CRC) screening by outreach to patients' homes using choice architecture informed by behavioral science principles.
The study is intended to compare the detection rate obtained by performing G-EYE® high definition colonoscopy vs. the detection rate obtained by performing ECV high definition colonoscopy.
This study focused on the key nodes, molecular events and regulatory mechanisms of intestinal microecological disorders that affect the malignant transformation of intestinal epithelial cells into tumors during the occurrence and development of colorectal cancer.
Umbrella study structure to independently and simultaneously assess the effects of the association of durvalumab and tazemetostat in multiple solid tumors.
This pilot study will explore the preliminary efficacy of a colorectal cancer (CRC) screening intervention delivered by virtual health assistants (VHAs). Participants will include 750 African American patients in the US between the ages of 45 and 75 recruited through Qualtrics panels. The main research question is: How does the integration of different levels of dialect density of the linguistic features of African American English (AAE) influence the perceived credibility of a Black VHA. Four types of VHAs will be presented to our patients: a VHA with Standardized American English (SAE) linguistic features, a VHA with a low level of African American English (AAE) linguistic features integrated, a VHA with a high level of African American English (AAE) linguistic features integrated, and a text-only control condition. Survey questions will be used to obtain credibility judgments about VHAs post-interaction.
