BackgroundIn cancer patients, malnutrition is associated with treatment toxicity, complications, reduced physical functioning, and decreased survival. The Prevalence of Malnutrition in Oncology (PreMiO) study identified malnutrition or its risk among cancer patients making their first medical oncology visit. Innovatively, oncologists, not nutritionists, evaluated the nutritional status of the patients in this study.MethodsPreMiO was a prospective, observational study conducted at 22 medical oncology centers across Italy. For inclusion, adult patients (>18 years) had a solid tumor diagnosis, were treatment-naive, and had a life expectancy >3 months. Malnutrition was identified by the Mini Nutritional Assessment (MNA), appetite status with a visual analog scale (VAS), and appetite loss with a modified version of Anorexia-Cachexia Subscale (AC/S-12) of the Functional Assessment of Anorexia-Cachexia Therapy (FAACT).FindingsOf patients enrolled (N=1,952), 51% had nutritional impairment; 9% were overtly malnourished, and 43% were at risk for malnutrition. Severity of malnutrition was positively correlated with the stage of cancer. Over 40% of patients were experiencing anorexia, as reported in the VAS and FAACT questionnaire. During the prior six months, 64% of patients lost weight (1–10 kg).InterpretationMalnutrition, anorexia, and weight loss are common in cancer patients, even at their first visit to a medical oncology center.

We have analyzed the proteomes of two human melanoma cell lines (A375 and 526), and of the human melanocytes, (FOM 78), by two-dimensional electrophoresis (2D-PAGE) and liquid chromatography - tandem mass spectrometry (LC-MS/MS). Our comparative proteomic analysis revealed that six proteins were over-expressed in both melanoma cell lines as compared to melanocytes: galectin-1, inosine-5'-monophosphate dehydrogenase 2, serine/threonine-protein phosphatase 2A 65 kDa regulatory subunit A alpha isoform, protein DJ-1, cyclophilin A and cofilin-1. We show, for the first time, that only specific isoforms of these molecules are over-expressed in melanoma. Different protein profiles were also found between each individual melanoma cell line and the melanocytes. s-Methyl-5-thioadenosine phosphorylase, ubiquitin and ribosomal protein S27 a precursor, the basic form of protein DJ-1, annexin a1, proliferation associated protein 2g4, isoform alfa-enolase of alfa-enolase, protein disulfide-isomerase precursor, and elongation factor 2 were more strongly expressed in A375 cells compared to melanocytes. In 526 cells, 60s acidic ribosomal protein p1 and calreticulin precursor were more highly expressed than in melanocytes. These molecular differences may help in better understanding melanoma development and its different responsiveness to therapies. The identified proteins could be exploited as biomarkers or therapeutic targets for melanoma.

Objectives To evaluate an enrichment training program targeted at home palliative care professionals in terms of its effects and participants’ satisfaction. The program had 2 main aims: give voice to professionals’ emotional fatigue and promote their personal resources. Methods One hundred twenty-three home palliative care professionals participated in 12 parallel training courses; each course consisted of four 3-hour meetings led by 2 trainers and involved about 10–15 participants. The program adopted the method and tools typical of the enrichment approach, with the insertion of an art therapy exercise in the central meetings. The topics addressed were the following: emotional awareness in care relationship; the recognition of the needs of the patient, the family, and the professional himself; the inevitability of the death of the patient; and the challenges and resources of the multidisciplinary care team. At the first (T1) and last (T2) meetings, participants filled in a self-report questionnaire assessing work emotional fatigue, empowerment, generativity, and satisfaction with the course. Results Participants were highly satisfied with the course. They reported a higher level of work emotional fatigue and a higher perception of personal resources, in terms of empowerment (both individual-oriented and relationship-oriented) and generativity at the end of the program than before. Significance of results Results confirm the need to provide home palliative care professionals with trainings in which they can express, share, and deal with personal and professional needs. This course gave voice to professionals’ work emotional fatigue and promoted their personal resources, while enhancing collaboration in the multidisciplinary team.
