The purpose of he study is to evaluate effects of dexmedetomidine on pain during radiofrequency ablation of liver and kidney tumours.
The purpose of this study is to understand if a home-based physical activity program can improve symptoms and physical function among patients with advanced stage cancer.
Despite broad awareness of the role that diet plays in increasing obesity risk, adherence to public health recommendations for maintaining healthy eating is low. Insights gained from weight loss intervention trials find that trial participants report difficulty in restricting calories, dissatisfaction with the pace of weight loss, inability to control eating, low palatability of recommended foods and strong food cravings. Indeed, recent systematic reviews provide empirical support that these subjective experiences that trial participants describe likely represent eating-related traits or phenotypes . While amassing evidence supports individual variation in these eating-related traits, to date there has been no systematic effort to characterize robust eating-related phenotypes. Proposed is a Sub-study initially planned to be piggy-backed on a planned Study being conducted by investigators at the University of North Carolina (UNC-- Linnan, Dilworth- Anderson & Evans). The UNC Parent Study was a feasibility study using community-based participatory research (CBPR) approaches to explore possible intervention strategies aimed to reduce the burden of chronic disease and cancer among African American families. The NHGRI-led eating behavior Sub-study is proposed to be integrated with the UNC Parent Study (hereafter referred to as Phase 1). The additional aims of the Sub-study (hereafter referred to as Phase 2) are to gain understanding of whether we can characterize clusters of eating-related behaviors that may be associated with adherence to weight management and weight outcomes. This current protocol lays out the specific qualitative activities planned for Phase 1 which include conducting structured interviews with Black Family Reunion organizers (N=8) and a sample of reunion participants (N=40). We also describe the larger quantitative survey proposed for Phase 2. Pending the feasibility of the sub-study with the African-American community, we will collect information on eating-related behaviors in a large sample of individuals (N=350). If the initial assessments (Phase1) prove that this is not a viable study to be conducted in that setting, we will consider other population groups and other settings. We are also considering Phase 3 activities if we identify clusters of eating-related phenotypes within individuals. Amended IRB applications will be submitted prior to launching Phase 3.
Many studies have demonstrated the beneficial effects of Adapted Physical Activity (APA) in different cancer types. It therefore seems necessary to assess spontaneous Physical Activity in order to integrate it to the overall calculation of physical activity in clinical practice. To assess the AP, two types of methods are validated : the subjective method using a questionnaries and objective method using a pedometer , accelerometer or measures calorimetry . Subjective method shows , good acceptability by patients and low cost but can sometimes lead to poor estimation of the level of activity. Objective methods obviously increase the accuracy of assessments but are more difficult to use for epidemiological studies , less accepted by the patient and more expensive. In this study the investigators will measure the spontaneous Daily Physical Activity by both methods andd evaluate the correclation.
SPANC stands for Study of the Prevention of Anal Cancer. There are more than 100 types of human papillomavirus (HPV). Some HPV types cause genital warts and other types cause more than 90% of anal cancer. Gay men are over 20 times more likely than others to develop anal cancer. SPANC is a study of anal (HPV) infection and related anal disease in gay men. The study will provide important information to guide the possible future introduction of anal cancer screening programs for gay men.
Cancer results when undifferentiated cells grow in an uncontrolled manner, crowding out normal cells, causing morbidity and ultimately mortality. The cancer stem cell theory suggests that most tumors undergo a process of differentiation through which a relatively rare cancer stem or progenitor cell (CSC) gives rise to more differentiated populations of cells (including transiently amplifying cells) comprising the bulk of the tumor. As a result of this cellular diversity, one or more cells within the tumor are likely to be resistant to therapy. Among cells resistant to a given therapy, only CSCs can repopulate the tumor. A key feature of this resistant subset of CSCs is that they repopulate a tumor resistant to the original intervention. The cellular programs driving the uncontrolled proliferation of many solid tumors result from aberrant activity of Wnt, Shh, and/or Notch signaling pathways in CSC. Thus, therapies that down-regulate the activity of these fundamental pathways in CSCs will be effective in the treatment of cancer. The investigators' research program focuses on the elucidation of signaling mechanisms, control of cellular processes and discovery of small molecules that selectively target Wnt, Shh, and Notch signaling pathways that are fundamental to CSCs. Our preliminary results identified a novel Notch associated protein NACK that functions as a transcriptional co-activator of Notch. Moreover, Nack is expressed in human solid tumors and is required for cell survival and tumor growth in notch -dependent tumor cells. The investigators' aim is to further interrogate the link between Notch and Nack.
The proposed project will answer key questions about implementing evidence-based health promotion interventions at small and low-wage worksites. Small, low-wage worksites will be randomized to receive HealthLinks (a free American Cancer Society program to disseminate evidence-based interventions), HealthLinks+ (which will include creating worksite wellness committees as part of the program), or to serve in a delayed control group. This approach will identify successful strategies for implementing evidence-based interventions at low-wage worksites to improve workers' cancer screening, healthy eating, physical activity, and tobacco cessation.
The curative treatment of thoracic (lung and oesophagus), digestive (gastric, pancreatic, hepatic, colorectal), and urologic (renal, bladder, prostatic) cancers needs a surgical resection. For patients aged of 70 years old and more, this surgery is associated to an increased morbid-mortality especially because of more frequent co-morbidities. Comprehensive geriatric assessment (CGA) allows distinguishing patients for whom a resection surgery can be complicated by high morbid-mortality or a loss of autonomy. It has been proved that for old patient population without cancer, CGA associated with a geriatric intervention plan (GIP) allows autonomy preservation, decrease of institution admission, and survival improvement. The reference study showed that a CGA associated to a GIP improves survival of old patients who had a cancer surgery. However this study included patients from 60 years old and the GIP consisted in 3 home visits and 5 phone calls during the 4 weeks following hospital discharge. We propose to perform a prospective and randomized study to evaluate the impact of a CGA with GIP in 70 years old and more patients with a thoracic, digestive or urologic cancer resection, respectively 1, 3, 6 and 12 months after discharge. CGA and GIP will focus on 8 distinct fields: autonomy, co-morbidities, co-medication, mobility, nutritional status, depression, cognitive function and social status. The impact of such a strategy on autonomy and survival has never been studied.
The Eastern Caribbean Health Outcomes Research Network (ECHORN) is a collaborative research study that examines the lifestyles, eating habits, and health behaviors associated with cancer, diabetes and heart disease in adult men and women living in the Eastern Caribbean.
