Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of immature myeloid cells that promote tumor progression. In this study, we investigated the effect of dectin-1 stimulation by yeast-derived particulate β-glucan in MDSC function and differentiation in cancer. In vivo treatment of mice bearing lewis lung carcinoma and mammary cell carcinoma with particulate β-glucan decreased tumor weight and splenomegaly, and reduced the accumulation of polymorphonuclear-MDSC (PMN-MDSC) but not monocytic-MDSC (M-MDSC) in the spleen and tumor. In addition, particulate β-glucan differentially modulated the function of different MDSC subsets; it enhanced PMN-MDSC respiratory burst and apoptosis, and induced the differentiation of M-MDSC into …

Family Care Giver Knowledge, Patient Illness Characteristics, And Unplanned Hospital Admissions In Older Adults With Cancer, Patricia Geddie
Electronic Theses and Dissertations
Unplanned hospital admissions (UHA) in older adult populations are a recurring problem in older adults with cancer. Older adults comprise approximately 60% of cancer diagnoses and receive the majority of cancer treatment. However, little is known about why older adults under treatment for cancer experience a high number of unplanned hospital admissions. A review of the literature provided few study findings and a gap in the current knowledge was identified regarding the factors associated with unplanned hospital admissions in older adults under treatment for cancer. A conceptual framework based on the literature and this researcher's clinical experienced guided this study. …
