    Notes: Abstract Bleeding from esophagogastric varices is a potentially deadly complication in patients with hepatosplenic schistosomiasis. The aim of this study is to establish indicators of variceal bleeding. We studied 40 patients with compensated hepatosplenic schistosomiasis and varices, analyzing four endoscopic (variceal size, red color signs, fundic varices, and congestive gastropathy), nine ultrasonographic (right and left hepatic lobe size, periportal and gallbladder wall thickness, portal and splenic veins diameter, spleen longitudinal axis and volume, and presence of collateral circulation), and five US-Doppler parameters (portal and splenic veins velocity and flow and portal vein congestion index). Patients were divided in two groups according to previous history of variceal bleeding. The group with bleeding episodes was again divided in two groups: with and without treatment, namely endoscopic sclerotherapy. All endoscopic parameters and two ultrasonographic (periportal thickness and portal vein diameter) were statistically different between the groups with and without previous bleeding. The likelihood index, adopted to determine the best parameters related to previous bleeding showed that the most important combinations are: gastropathy and red signs followed by portal vein diameter and variceal size. In conclusion, although aware of the limits of the statistical analysis due to the small number of patients, our results demonstrated that endoscopic and US parameters (isolated or combined) can identify patients with a high risk of variceal bleeding, allowing physicians to optimize prophylactic therapy.

    Description: The core was collected manually from a boat employing a gravity core sampler. The core was sliced every two centimeters in the field, packed in individual identified plastics bags, and kept refrigerated. The THIII sediment core (N 28°01.626, W 12°16.558), measuring 48 cm, was recovered in one of the sections of the main water entrance channel in the Lagoon. This site is approximately seven meters deep and lies between two islets of exposed sediment dominated by marine grass specimens of *Zostera noltii*. During the sampling, salinity at the site was 40 PSU (Practical Salinity Unit). Due to its proximity to the inlet, this site is highly influenced by the seawater entrance and ocean nutrients. Aiming the recognition of the environmental changes at this point of the lagoon, we have performed the following measurements in the core's sediments: isotopic ratio of C, dating (210Pb and 137Cs calibration), sedimentation rate, mean grain size, Chlorophyll, Total Organic Carbon (TOC), C/N elemental ratio and C/S elemental ratio.
