Prognosis in pediatric hematologic malignancies is associated with serum concentration of mannose-binding lectin-associated serine protease-2 (MASP-2)

BACKGROUND: Mannose-binding lectin (MBL) and MBL-associated serine protease-2 (MASP-2) are key components of the lectin pathway of complement activation. Their serum concentrations show a wide interindividual variability. This study investigated whether the concentration of MBL and MASP-2 is associated with prognosis in pediatric patients with cancer. METHODS: In this retrospective multicenter study, MBL and MASP-2 were measured by commercially available ELISA in frozen remnants of serum taken at diagnosis. Associations of overall survival (OS) and event-free survival (EFS) with MBL and MASP-2 were assessed by multivariate Cox regression accounting for prognostically relevant clinical variables. RESULTS: In the 372 patients studied, median serum concentration of MBL was 2,808 microg/L (range, 2-10,060) and 391 microg/L (46-2,771) for MASP-2. The estimated 4-year EFS was 0.60 (OS, 0.78). In the entire, heterogeneous sample, MBL and MASP-2 were not significantly associated with OS or EFS. In patients with hematologic malignancies, however, higher MASP-2 was associated with better EFS in a significant and clinically relevant way (hazard ratio per tenfold increase (HR), 0.22; 95% CI, 0.09-0.54; P = 0.001). This was due to patients with lymphoma (HR, 0.11; 95% CI, 0.03-0.47; P = 0.003), but less for those with acute leukemia (HR, 0.35; 95% CI, 0.11-1.15; P = 0.083). CONCLUSION: In this study, higher MASP-2 was associated with better EFS in pediatric patients with hematologic malignancies, especially lymphoma. Whether MASP-2 is an independent prognostic factor affecting risk stratification and anticancer therapy needs to be assessed in prospective, disease-specific studies.

Carbonate, organic carbon, pyrolysis and composition of the extracts at DSDP Holes 76-534A and 44-391

The geochemical studies of Sites 534 and 391 and their comparison allow us to improve the chemical characterization of different geological formations dating from the early Callovian to the Maestrichtian along the continental margin of eastern North America. Three of the formations are favorable for the preservation of organic matter: (1) the unnamed formation (middle Callovian to Oxfordian), (2) the Blake-Bahama Formation (Berriasian to Barremian), and (3) the Hatteras Formation (Aptian to Cenomanian). The organic matter is mainly detrital, except for a few organic-rich layers where a contribution of aquatic material occurs. In these organic-rich layers, the petroleum potential is medium to good. Maturation has not quite reached the beginning of the oil window even for the deepest organic material.

Thickness and duration of biostratigraphic zones, assemblages, ages and sedimentation rates at DSDP Sites 76-534 and 44-391

In this Initial Report of the Deep Sea Drilling Project, detailed studies of Sites 533 (gas hydrates) on the Blake Outer Ridge and 534 (oldest ocean history) in the Blake-Bahama Basin have provided answers to many geological and geophysical questions posed over the decade that deep drilling has been undertaken in this part of the western North Atlantic. The history of drilling and a historical review of key scientific accomplishments have been presented in the Introduction (Gradstein and Sheridan, this volume). In this final chapter we review highlights of new geological, geophysical and paleoceanographic interpretations presented in this volume, and offer a critical review of this information. We conclude with a listing of some outstanding problems and recommendations for future research, including data collection.
