Purpose: To assess the impact of taxes, warnings, and a combination of taxes and warnings on US adults' decisions to purchase products that contain red meat in an online grocery store. Procedures (methods): Participants will be recruited from Prime Panels (an online panel research company). Following online consent, participants will be assigned to one of four trial arms: 1) Control (no warning and no tax), 2) Warnings (all products that contain red meat have a health warning and environmental warning), 3) Tax (30% tax on products that contain red meat), and 4) Combined warning and tax (all products that contain red meat will have the two warnings and a 30% tax). Then, participant will enter an online grocery store reflecting their assigned arm. The participant will be instructed to complete a shopping task in the online grocery store. After completing the shopping task, participants will be redirected to an online survey and answer a series of questions about the shopping task, labels (excluding tax and control groups), and taxes (excluding warning and control groups). Questions will also include standard demographic and health related variables.
A pathological complete response (pCR) after surgery occurs in approximately 20% of rectal cancer patients submitted to neoadjuvant chemotherapy, with apparent survival benefit. This group could, potentially, be spared the morbidity of surgery. The diversified response to neoadjuvant chemotherapy (nCRT) amongst tumors suggests a complex relationship between tumor biology and response possibly due to a number of genetic or molecular pathways that might regulate chemoradiosensitivity. Accumulating evidence indicated that circulating cell-free nucleic acids can be a promising biomarker of response, in liquid biopsy, for rectal cancer. The concentration of baseline plasma cell-free DNA (cfDNA) appears significantly higher in responders compared to non-responders. The objective of this study is to investigate the potential role of cfDNA as a marker of pCR (or partial response) to nCRT as well as a marker of outcomes (overall survival and disease-free survival). The investigators are conducting a prospective, observational, cohort, non-randomized study of consecutive patients with locally advanced rectal cancer submitted to nCRT, followed by surgical excision 6-12 weeks later. Patients are assigned to groups according to their pathological response to nCRT. A total of 20 patients with complete pathological response, 50 partial response and 50 non-responders will be selected over a year and followed for another year. Participants will be observed and examined during the entire course of treatment and the follow-up period. Serial analysis of cfDNA through liquid biopsies will be performed in consecutive patients at specific time points (pre-nCRT, post-nCRT and postoperative week 1), incorporating analysis of concentration, dimension of DNA fragments, % of mutation frequency (CIN, APC, p53, MSI, KRAS, BRAF, EGFR, cKIT) and next-generation sequencing of tumour biopsy and surgical specimens. This study will serve as the feasibility of a larger, comparative study.
The prevalence of malnutrition is common among patients with colorectal cancer. Chemotherapy induced side effects may impact negatively on nutrition intake thus increase the risk of malnutrition and serious complications for patients. Purpose is to test the effect of empowering education on activation and knowledge level among patients with colorectal cancer during the chemotherapy. Secondary outcomes are quality of life and malnutrition. A two-arm, single center, patient blinded superiority trial with stratified randomization (1:1) and with repeated measures is used to measure the effectiveness of face-to-face education on nutrition intake related chemotherapy induced side-effects' self-care compared to standard care. Eligibility criteria are adult patients diagnosed with colorectal cancer and receiving intra venous chemotherapy treatment. Patients are recruited in one university hospital outpatient clinic in Finland. Experienced oncology nurse delivers the intervention two weeks after the first chemotherapy. Primary outcomes are activation in self-care and knowledge level. Secondary outcomes are quality of life and risk of malnutrition measured at baseline (M0) and after eight (M1) and 16 weeks (M2) after the intervention. The study will provide knowledge of nurse-led educational intervention on self-care among patients with colorectal cancer. The findings will contribute to patient education and self-care, thus better quality of life.
The purpose of this study is to test the usability of the Plan To Thrive smartphone application with cancer survivors. This study will involve three visits (baseline, follow-up, and feedback assessments). Between the baseline and follow-up time points, patients will undergo a 90-day period in which they will engage with app content. It is hypothesized that cancer survivors in this study will find the smartphone application, Plan to Thrive, an acceptable and feasible way to access post-treatment information. In addition, the investigators will explore preliminary efficacy by examining changes over time in primary (patient activation, patient knowledge and adherence to follow-up care recommendations and health behaviors) and secondary outcomes [symptom burden, health-related quality of life and patient satisfaction].
The purpose of this research study is to look at how tumors responds to a short course of radiation (5 days) followed by 8 cycles of chemotherapy.
Anastomotic leakage is a serious complication after LAR with high morbidity and mortality rates. Early diagnosis and treatment is mandatory. The primary aim of the present study is to investigate the clinical use of peritoneal microdialysis and whether is able to detect anastomotic leakage prior to clinical symptoms develops.
