RESUMEN

OBJECTIVE: To assess the feasibility of a new device for telemonitoring vital parameters during iloprost infusion. MATERIALS AND METHODS: In a pilot study, patients with systemic sclerosis received iloprost infusion while being telemonitored with Umana T1 Heart Monitor, within the hospital, under the supervision of family/community nurses and rheumatologists. Patients were administered a questionnaire to obtain information on satisfaction, practicability, and compliance with the new monitoring device. RESULTS: Data recorded by the device for blood pressure, heart rate, and oximetry were concordant with those registered directly by nurses. Most patients found the device useful and thought it could be used at home, even while working. CONCLUSIONS: Umana Heart Monitor T1 could be a valuable aid in at-home iloprost therapy in patients with systemic sclerosis.

RESUMEN

BACKGROUND: Myxoid liposarcoma (MLS) is the second most common subtype of liposarcoma, and metastasis occurs in up to one-third of cases. However, the mechanisms of invasion and metastasis remain unclear. Tumour-associated macrophages (TAMs) have important roles in tumour invasion, metastasis, and/or poor prognosis. The aim of this study was to investigate the relationship between TAMs and MLS. METHODS: Using 78 primary MLS samples, the association between clinical prognosis and macrophage infiltration was evaluated by immunochemistry. The effects of macrophages on cell growth, cell motility, and invasion of MLS cell lines were investigated in vitro. In addition, clinicopathological factors were analysed to assess their prognostic implications in MLS. RESULTS: Higher levels of CD68-positive macrophages were associated with poorer overall survival in MLS samples. Macrophage-conditioned medium enhanced MLS cell motility and invasion by activating epidermal growth factor receptor (EGFR), with the key ligand suggested to be heparin-binding EGF-like growth factor (HB-EGF). The phosphoinositide 3-kinase/Akt pathway was mostly involved in HB-EGF-induced cell motility and invasion of MLS. The expression of phosphorylated EGFR in MLS clinical samples was associated with macrophage infiltration. In addition, more significant macrophage infiltration was associated with poor prognosis even in multivariate analysis. CONCLUSIONS: Macrophage infiltration in MLS predicts poor prognosis, and the relationship between TAMs and MLS may be a new candidate for therapeutic targets of MLS.
