Reduction of circulating cholesterol and apolipoprotein levels during sepsis

Sepsis with multiple organ failure is frequently associated with a substantial decrease of cholesterol levels. This decrease of cholesterol is strongly associated with mortality suggesting a direct relation between inflammatory conditions and altered cholesterol homeostasis. The host response during sepsis is mediated by cytokines and growth factors, which are capable of influencing lipid metabolism. Conversely lipoproteins are also capable of modulating cytokine production during the inflammatory response. Therefore the decrease in circulating cholesterol levels seems to play a crucial role in the pathophysiology of sepsis. In this review the interaction between cytokines and lipid metabolism and its clinical consequences will be discussed

Diagnostic routes and time intervals for patients with colorectal cancer in 10 international jurisdictions; findings from a cross-sectional study from the International Cancer Benchmarking Partnership (ICBP)

OBJECTIVE: International differences in colorectal cancer (CRC) survival and stage at diagnosis have been reported previously. They may be linked to differences in time intervals and routes to diagnosis. The International Cancer Benchmarking Partnership Module 4 (ICBP M4) reports the first international comparison of routes to diagnosis for patients with CRC and the time intervals from symptom onset until the start of treatment. Data came from patients in 10 jurisdictions across six countries (Canada, the UK, Norway, Sweden, Denmark and Australia). DESIGN: Patients with CRC were identified via cancer registries. Data on symptomatic and screened patients were collected; questionnaire data from patients\u27 primary care physicians and specialists, as well as information from treatment records or databases, supplemented patient data from the questionnaires. Routes to diagnosis and the key time intervals were described, as were between-jurisdiction differences in time intervals, using quantile regression. PARTICIPANTS: A total of 14 664 eligible patients with CRC diagnosed between 2013 and 2015 were identified, of which 2866 were included in the analyses. PRIMARY AND SECONDARY OUTCOME MEASURES: Interval lengths in days (primary), reported patient symptoms (secondary). RESULTS: The main route to diagnosis for patients was symptomatic presentation and the most commonly reported symptom was \u27bleeding/blood in stool\u27. The median intervals between jurisdictions ranged from: 21 to 49 days (patient); 0 to 12 days (primary care); 27 to 76 days (diagnostic); and 77 to 168 days (total, from first symptom to treatment start). Including screen-detected cases did not significantly alter the overall results. CONCLUSION: ICBP M4 demonstrates important differences in time intervals between 10 jurisdictions internationally. The differences may justify efforts to reduce intervals in some jurisdictions

Psychological symptoms

Psychological symptoms are highly prevalent in people requiring palliative care. They are much more challenging to elicit, and more controversy exists about what is normal and what might require intervention than physical symptoms. There are significant issues in determining what is normal and what is not. Sadness, distress, anxiety, and depression can coexist and require careful assessment. Management of psychological symptoms and conditions can broadly be considered in terms of non-pharmacological and pharmacological therapies, “the talking and the drug therapies.” These are not mutually exclusive, and for people with limited energy, failing cognition, and limited time, some pragmatic decisions may be necessary. To be distressed and immobilized by emotion is not normal. Depression is not a normal part of dying. There should be discussion about the nature of psychological issues and conditions, explanation of common somatic symptoms, and a plan for intervention and support. The burden on the carer, both professional and personal, in such situations should not be underestimated.Gregory B. Crawfor
