Plasma concentrations of morphine, morphine-6-glucuronide and morphine-3-glucuronide and their relationship with analgesia and side effects in patients with cancer-related pain.
Morphine, the recommended drug for the management of moderate to severe cancer pain, is metabolized predominantly to the glucuronides morphine-6-glucuronide (M6G) and morphine-3-glucuronide (M3G). The quantitative clinical importance of these metabolites following the administration of oral morphine is unclear. This study investigates the relationship between plasma concentrations of morphine (M), M6G, M3G and clinical effects in patients receiving sustained release oral morphine for cancer-related pain. ⋯ Similarly, there was no significant relationship between high and low plasma concentrations and clinical effect. This study did not identify a simple relationship between plasma concentrations of morphine, morphine metabolites or metabolite ratios and clinical effects in patients with cancer and pain who were receiving chronic oral morphine therapy. Although overall pain control was good, there was marked interpatient variability in the dose of morphine and the plasma concentrations necessary to achieve this degree of analgesia.

An ad libitum schedule for conversion of morphine to methadone in advanced cancer patients: an open uncontrolled prospective study in a Chinese population.
Methadone has been used as an alternative strong opioid to morphine in the management of cancer pain. The conversion of morphine to methadone is not straightforward because of the high individual variability and unpredictability in the pharmacokinetics of methadone. An ad libitum schedule for conversion of morphine to methadone was used in 37 cancer patients who had intolerable morphine-related side effects or had pain not satisfactorily controlled by morphine. ⋯ The median time required to achieve good pain control was three days (range 1-11 days). A majority (88.6%) of morphine-related adverse effects improved or resolved after conversion to methadone. This ad libitum schedule is effective in conversion of morphine to methadone in these patients.

ReviewWhat is the best way to help caregivers in cancer and palliative care? A systematic literature review of interventions and their effectiveness.
Informal carers in cancer and palliative care are known to have high needs and psychological morbidity, yet a literature review identified few targeted interventions. This systematic review of interventions for carers of patients using home cancer and palliative care services searched Medline, CancerLit, Psycinfo and Cinahl databases. The terms used were carer(s), caregiver(s), palliative and cancer. ⋯ Methodological challenges may mean alternatives to 'pure' RCTs should be considered. The current evidence contributes more to understanding feasibility and acceptability than to effectiveness. Practitioners and evaluators must prioritize the further development of intervention studies.

ReviewThe palliative care needs of people with intellectual disabilities: a literature review.
People with intellectual disabilities are among the most disadvantaged groups in society. A literature review was conducted aiming to answer the following question: What are the palliative care needs of people with intellectual disabilities? The literature review covers case histories, morbidity and mortality patterns for people with intellectual disabilities, their healthcare needs and primary care provision, the way they may present symptoms, their conceptualization of illness and death and issues around education and training. ⋯ It is suggested that future studies will need to include the views and experiences of people with intellectual disabilities themselves. Areas for possible future development include symptom assessment, evaluation of current practice and access to services and the development of information and training materials.
