Frequency and Indications of Parenteral Nutrition in an Acute Palliative Care Unit.
The aim of this study was to estimate the use of parenteral nutrition (PN) in advanced cancer patients enrolled in an acute pain relief and palliative care unit of a comprehensive cancer center and the appropriateness of the criteria to select patients for PN. Fourteen out of 750 patients (1.8%) admitted to an acute palliative care unit were administered PN. Patients were referred from various settings. ⋯ This study shows that decisions to start or to stop PN were individually based on multiple considerations, not only clinical. Goals may vary from expected clinical benefits to compassionate use. The administration of PN should be assessed carefully and individually approached.

Meta AnalysisCoffee consumption and prostate cancer risk: a meta-analysis of cohort studies.
This meta-analysis was conducted to assess the association between coffee consumption and prostate cancer risk. Thirteen cohort studies with 34,105 cases and 539,577 participants were included in the meta-analysis. The summary relative risks (RRs) with 95% confidence intervals (CIs) for different coffee intake levels were calculated. ⋯ In subgroup analysis of prostate cancer grade, the summary RRs were 0.89 (95% CI: 0.83-0.96) for nonadvanced, 0.82 (95% CI: 0.61-1.10) for advanced and 0.76 (95% CI: 0.55-1.06) for fatal diseases. Our findings suggest that coffee consumption may be associated with a reduced risk of prostate cancer and it also has an inverse association with nonadvanced prostate cancer. Because of the limited number of studies, more prospective studies with large sample size are needed to confirm this association.
