The aim of this investigation was to determine the prognostic value of coagulation abnormalities in a defined subset of patients with acute head injury. Prothrombin time, accelerated partial thromboplastin time (APTT), thrombin clotting time, fibrinogen assay, platelet count, fibrin degradation products (FDP) were assayed in 204 patients with acute closed head injury. Their values were graded on a score 0-3 and the sum score for each patient regarded as the disseminated intravascular coagulation (DIC) score. Moderate to severe DIC scores were evident in 38% of the cohort. At least one parameter was abnormal in 71% of patients. The DIC score correlated inversely with the Glasgow coma score (GCS) (p < 0.0001). In the GCS 13-15 subset, FDP scores were significant predictors of poor outcome (p < 0.001). In the GCS 6-12 subset, the APTT score (p < 0.001), and DIC score (p < 0.0001) predicted an adverse outcome. The DIC scores were significantly abnormal in most patients who had a poor outcome, without evidence of adverse predictors on CT. Logistic regression analysis confirmed the independent predictive capacity of APTT, FDP and DIC scores when values for GCS were fixed. Abnormal haemostatic parameters may enhance the predictive ability in subsets of patients with acute head injury defined by clinical or CT predictors.
Decline in forest productivity due to forest conversion is defining the Bornean landscape. Responses of bacterial communities due to land-use changes are vital and could define our understanding of ecosystem functions. This study reports the changes in bacterial community structure in organic soil (0-5 cm; O-Horizon) and organic-mineral soil (5-15 cm; A-Horizon) across Maliau Basin Conservation Area old growth forest (MBOG), Fragment E logged forest (FELF) located in Kalabakan Forest Reserve to Benta Wawasan oil palm plantation (BWOP) using two-step PCR amplicon analysis of bacteria DNA on Illumina Miseq next generation sequencing. A total of 30 soil samples yielded 893,752-OTU reads at ≥97% similarity from 5,446,512 good quality sequences. Soil from BWOP plantation showed highest unshared OTUs for organic (49.2%) and organic-mineral (50.9%) soil. MBOG soil showed a drop in unshared OTUs between organic (48.6%) and organic-mineral (33.9%). At phylum level, Proteobacteria dominated MBOG but shifted to Actinobacteria in logged and plantation soil. Present findings also indicated that only FELF exhibited change in bacterial communities along the soil depth, moving from the organic to the organic-mineral layer. Both layers of BWOP plantation soils deviated from other forests' soil in β-diversity analysis. To our knowledge, this is the first report on transitions of bacterial community structures with different soil horizons in the tropical rainforest including Borneo, Sabah. Borneo tropical soils form a large reservoir for soil bacteria and future exploration is needed for fully understanding the diversity structure and their bacterial functional properties.
