Nerve growth factor receptor (NGF-R) has been shown to have antiproliferative, differentiative, or apoptotic effects on some types of tumor cells, whereas in others it may have mitogenic activity. The immunohistochemical distribution of NGF-R was analyzed in a series of tissue samples from breast cancer patients and its relationship with other clinical and pathological parameters was studied. The distribution of NGF-R was evaluated by immunohistochemistry in frozen tissue samples of 46 breast cancer patients (ME20-4 monoclonal anti-NGF-R). NGF-R immunoreactivity was localized in the plasma membrane of myoepithelial cells, differentiated ducts, neoplastic cells, blood vessels, and nerve fibers in 26 patients (57%). Less differentiated neoplastic tissues were usually NGF-R negative. NGF-R immunoreactivity was associated with estrogen receptor (ER) status (p = 0.02), small tumor dimension (pT) (p = 0.04), low histologic grade (G1-G2) (p < 0.05), old age (p = 0.02), menopause (p = 0.02), and long disease-free survival (DFS) (median follow up 86 months; p = 0.03; independently from ER, pT, age, menopause by multivariate analysis, p = 0.0078). The expression of NGF-R immunoreactivity by breast cancer patients with long DFS may represent a crucial step both in the differentiation status of neoplasia and in the host immune mechanism controlling tumor growth and metastasization.

The prevalence of burnout in oncology staff was compared with that of the ophthalmology staff, who normally present a low prevalence of burnout as described in this literature. The correlation of burnout with the emotion of anger was also investigated. Thirty-six subjects working in an oncology department and 32 working in an ophthalmology department were examined using the Maslach Burnout Inventory and the State-Trait Anger Expression Inventory. The oncology group showed higher mean scores on the MBI Emotive Exhaustion and Depersonalization scales with respect to ophthalmology staff. Correlation analysis showed that increasing burnout was associated with higher anger expressed towards the environment and loss of anger control. Anger, as a response to frustration, appears to be a feature constantly associated with the clinical expression of burnout and it should not be underestimated in theoretical and preventive contexts.

This is the first cluster randomized trial aiming to demonstrate that a structured modality of providing information reduces psychological distress. We did not find this, but we believe results should be interpreted cautiously, particularly because of the low compliance with PIS implementation. Context analysis preceding such interventions is essential.

Our data indicate that H. pylori infection is associated with active interleukin‐18 production in patients with chronic gastritis. Different cell types appear to be involved in this activity and may play a role in the development of immunopathologic damage.

Our findings suggest that the loss of TRF1 expression capability, as a result of down-regulation of TRF1 expression in malignant gliomas cells, may play a role in the malignant progression of astroglial brain tumors.
