Alterations in emotional responses (pleasantness/unpleasantness) induced by sniffing food odors during chemotherapy in patients with lung cancer.

Background: Patients receiving chemotherapy experience anorexia and food aversion in their daily lives, and one of the causes is the smell of food. However, it is not clear why the aversion to these smells occurs. This study aimed to determine the emotional responses of patients when they sniff representative food odors during chemotherapy and to investigate factors influencing smell-induced food aversion.

Multidisciplinary nutritional support for autologous hematopoietic stem cell transplantation: a cost-benefit analysis.

Objective: The objective of the present study was to evaluate the economic and clinical efficacy of a multidisciplinary nutritional support team (NST) for autologous stem cell transplantation.

Methods: We performed a retrospective cost-benefit analysis of autologous stem cell transplantation (ASCT) in patients with and without NST intervention at a single institute. Patients (n = 120) had undergone 169 ASCTs, 67 before the commencement of NST intervention in September 2005 and 102 after September 2005.
