Sarcopenia: looking to muscle mass to better manage pancreatic cancer patients Purpose of review Overall survival of patients with pancreatic cancer is strongly conditioned by tumor biology and the incidence of malnutrition and metabolic disorders. In this landscape, the assessment of body composition is crucial to properly manage the clinical implications of muscle wasting. The pathogenesis of this condition is the result of a complex interplay between cancer and the host. In particular, sarcopenia is induced by an inadequate nutritional intake, hormonal abnormalities, inflammation and imbalance between anabolic and catabolic pathways. Recent findings Recent evidences have highlighted the role of sarcopenia in cancer patients, revealing a prognostic impact on morbidity, mortality and survival. Summary The occurrence of sarcopenia could amplify chemotherapy-induced toxicities, prolong hospitalizations and reduce adherence to anticancer treatment, worsening quality of life and survival. Although considerable efforts have been made to develop treatment strategies, no effective interventions have been identified so far. Nevertheless, if promptly and adequately supported, pancreatic cancer might benefit from adopted dietary intervention to avoid further loss of lean mass.

Dietetic assessment and intervention in lung cancer Purpose of review Systemic therapy for lung cancer is increasing in intensity and duration. European nutrition guidelines suggest screening for weight loss and malnutrition, however acknowledges there is a lack of evidence. We discuss current data round this issue and identify opportunities for further research. Recent findings International guidelines now exist to aid the definition of weight loss in cancer, including cachexia, sarcopenia and malnutrition. These allow consistent definition of overlapping, but distinct clinical syndromes. Nutritional status can be assessed in a range of ways including questionnaires, functional assessments, blood markers, physical activity, weight and BMI. Weight loss is commonly associated with a proinflammatory state. Future treatment is likely to be a combination of dietetic support and pharmacological treatment of cachexia. Summary There is a paucity of data on dietetic intervention. It is potentially quick, inexpensive and patient specific, using a holistic approach to aid patients who are malnourished or at risk of malnutrition. Lung cancer-related weight loss is common, further strategies are needed to effectively assess and intervene. Dietetic intervention has the potential to improve patients’ quality of life and outcomes. Correspondence to Dr Iain Phillips, Edinburgh Cancer Centre, Western General Hospital, Edinburgh, UK.

Ketamine and lidocaine infusions decrease opioid consumption during vaso-occlusive crisis in adolescents with sickle cell disease Purpose of review Recurrent exposure to opioids can lead to development of opioid tolerance and opioid-induced hyperalgesia through activation of N-methyl-D-aspartate receptors. N-methyl-D-aspartate receptor antagonists ketamine and lidocaine can modulate development of opioid tolerance and OIH. This study evaluated the utility of ketamine and/or lidocaine in decreasing opioid consumption during acute pain episodes in adolescents with sickle cell disease. There has been an increased effort to promote opioid-sparing pain relieving methods given the ongoing opioid epidemic. Recent findings There have been six studies published over the past decade that highlight the ability of ketamine to reduce opioid consumption in the management of sickle cell disease-related pain, primarily in adult patients. There has been one study (2015) that demonstrated a similar benefit with lidocaine, however this was also in adult patients. Summary We retrospectively evaluated treatment with ketamine and/or lidocaine infusions in adolescents hospitalized for vaso-occlusive crisis (VOC). Patients served as self-controls using a comparison with a previous control admission for VOC. The use of ketamine and/or lidocaine as adjuncts to opioids resulted in lower daily opioid consumption in three of four patients. Our study suggests that ketamine and/or lidocaine infusions may be useful adjuncts in reducing opioid exposure during VOC pain. Correspondence to Doralina L.
