Thrombocytopenia and platelet dysfunction contribute to hemorrhagic complications in the myelodysplastic syndromes (MDS). Reliable data regarding the frequency and consequences of thrombocytopenia in MDS are lacking. An extensive literature review indicated that the prevalence of thrombocytopenia (platelets <100 3 10 9 /L) in MDS ranged from 40% to 65%; the median frequency of thrombocytopenia prior to any MDS therapy was 65% (range, 23-93% high-risk disease. Treatment-related thrombocytopenia was observed in studies that involved azacitidine, tipifarnib, decitabine, lenalidomide, sirolimus, and combination chemotherapy with idarubicin, cytarabine, and topotecan. The reported incidence of hemorrhagic complications in the literature ranged from 3% to 53%, and the frequency of hemorrhagic deaths ranged from 14% to 24%.At MDACC, 460 patients had a coded cause of death: hemorrhage as a contributory cause of death, 20%; hemorrhage as the only cause of death, 10%. Thrombocytopenia was common in MDS, and there was an increased prevalence in higher risk IPSS categories. Many approved and investigational MDS therapies caused or exacerbated preexisting thrombocytopenia. The incidence of severe bleeding in MDS was greater than reported in current guidelines. Cancer

Graphical Abstract Highlights d Pegilodecakin induces systemic and intratumoral CD8 + T cell activation in patients d PD-1 + Lag3 + CD8 + T cells and previously undetected T cell clones are expanded d IFN-g, IL-18, GranzymeB, and FasL are elevated across tumor types d The magnitude of systemic immune activation correlates with tumor response SUMMARYTumor-reactive T cell exhaustion prevents the success of immune therapies. Pegilodecakin activates intratumoral CD8 + T cells in mice and induces objective tumor responses in patients. Here we report that pegilodecakin induces hallmarks of CD8 + T cell immunity in cancer patients, including elevation of interferon-g and GranzymeB, expansion and activation of intratumoral CD8 + T cells, and proliferation and expansion of LAG-3 + PD-1 + CD8 + T cells. On pegilodecakin, newly expanded T cell clones, undetectable at baseline, become 1%-10% of the total T cell repertoire in the blood. Elevation of interleukin-18, expansion of LAG-3 + PD-1 + T cells and novel T cell clones each correlated with objective tumor responses. Combined pegilodecakin with anti-PD-1 increased the expansion of LAG-3 + PD-1 + CD8 + T cells.

OBJECTIVES. The purpose of the study was to determine the clinical and economic impact of alternative contraceptive methods. METHODS. Direct medical costs (method use, side effects, and unintended pregnancies) associated with 15 contraceptive methods were modeled from the perspectives of a private payer and a publicly funded program. Cost data were drawn from a national claims database and MediCal. The main outcome measures included 1-year and 5-year costs and number of pregnancies avoided compared with use of no contraceptive method. RESULTS. All 15 contraceptives were more effective and less costly than no method. Over 5 years, the copper-T IUD, vasectomy, the contraceptive implant, and the injectable contraceptive were the most cost-effective, saving $14,122, $13,899, $13,813, and $13,373, respectively, and preventing approximately the same number of pregnancies (4.2) per person. Because of their high failure rates, barrier methods, spermicides, withdrawal, and periodic abstinence were costly but still saved from $8933 to $12,239 over 5 years. Oral contraceptives fell between these groups, costing $1784 over 5 years, saving $12,879, and preventing 4.1 pregnancies. CONCLUSIONS. Contraceptives save health care resources by preventing unintended pregnancies. Up-front acquisition costs are inaccurate predictors of the total economic costs of competing contraceptive methods.
