'Containment' as an analytical framework for understanding patient delay: A qualitative study of cancer patients' symptom interpretation processes

Recent decades have seen much variation in survival and mortality among European cancer patients, with rather small increases in survival, especially among patients in UK and Denmark. This poor outcome has been ascribed tentatively to patient delay since an estimated 20-25% of all cancer patients report having experienced cancer-related symptoms for more than three months before seeking care. In this article we analyse semi-structured interviews with 30 adult Danish cancer patients and their families. Special focus is given to symptom interpretation processes, and how these processes potentially delay care-seeking decisions. The paper adopts a contextual approach inspired mainly by the sociologist (Alonzo, 1979) and (Alonzo, 1984) concept of containment. Alonzo's theory is supplemented with recent anthropological and sociological literature on how people establish the relation between bodily sensations and symptoms and decide how to respond adequately to these. We present an analysis illustrating that bodily sensations and symptoms are potentially contained in a dynamic interplay of factors related to specific social situations, life biographies and life expectations and their accordance with culturally acceptable values and explanations. Finally, we discuss the implications of the analysis for future studies on patient delay.Denmark Patient delay Care seeking Symptom interpretation Sensations Cancer

Creating knowledge about adverse drug reactions: A critical analysis of the Danish reporting system from 1968 to 2005

Data on adverse drug reactions (ADRs) have been collected in Denmark since 1968 and the process is ongoing. This article explores knowledge created by the system, including how the collected data have been used to monitor the safety of licensed drugs. Nonaka's theory of knowledge creation was used to discriminate between tacit and explicit knowledge. A total of 56,802 ADR case reports were received from 1968 to 2005. The analysis shows a rather stable number of ADR cases from 1980, with about 2000 reports per year. The distribution of cases into serious and non-serious ADRs has been one to four throughout the period under study, but with large variations. Analysis of selected ADR cases shows that the system lacked the potential to capture available knowledge. Consequently the ADR reports have had limited value and significance in the process of creating scientific knowledge. Thus, the analysis questions the way available data can become explicit as a basis for regulatory decisions and whether all data can become knowledge, including who decides what knowledge is.Adverse drug reaction reporting systems Drug monitoring Product surveillance Post marketing Knowledge Denmark

Characterization of Growth Hormone Resistance in Experimental and Ulcerative Colitis

Growth hormone (GH) resistance may develop as a consequence of inflammation during conditions such as inflammatory bowel disease, encompassing ulcerative colitis (UC). However, the specific role of the GH–insulin growth factor (IGF)-1-axis and/or the functional consequences of GH resistance in this condition are unclear. In situ hybridization targeting the GH receptor (GHR) and relevant transcriptional analyses were performed in patients with UC and in IL-10 knock-out mice with piroxicam accelerated colitis (PAC). Using cultured primary epithelial cells, the effects of inflammation on the molecular mechanisms governing GH resistance was verified. Also, the therapeutic potential of GH on mucosal healing was tested in the PAC model. Inflammation induced intestinal GH resistance in UC and experimental colitis by down-regulating GHR expression and up-regulating suppressor of cytokine signalling (SOCS) proteins. These effects are driven by pro-inflammatory mediators (tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6) as confirmed using primary epithelial cells. Treatment of experimental colitis with GH increased IGF-1 and body weight of the mice, but had no effects on colonic inflammation or mucosal healing. The high transcriptional similarity between UC and experimental colitis accentuates the formation of intestinal GH resistance during inflammation. Inflammation-induced GH resistance not only impairs general growth but induces a state of local resistance, which potentially impairs the actions of GH on mucosal healing during colitis when using long-acting GH therapy
