Avian injury quantification using the Shoreline Deposition Model and model sensitivities.

Deposition models, such as the Shoreline Deposition Model (SDM) used to quantify nearshore avian injuries resulting from the 2010 Deepwater Horizon (DWH) oil spill, were developed to improve the estimates of nearshore avian mortality resulting from the release of oil into coastal and marine environments. Unlike earlier approaches to injury quantification, such as simple counts of carcasses on the shoreline, a modeling approach allows trustees to evaluate the precision of their estimate (i.e.

Evaluation of the fate of carcasses and dummies deployed in the nearshore and offshore waters of the northern Gulf of Mexico.

In response to the Deepwater Horizon oil spill, federal and state agencies conducted field studies to develop inputs for a shoreline deposition model used to estimate nearshore avian mortality resulting from the spill. A 2011 carcass drift study was designed to generate data on the likelihood that birds that died on the water would deposit along the northern Gulf of Mexico coast (rather than becoming lost at sea). In the case of the Deepwater Horizon oil spill, carcass losses at sea accounted for a significant portion of nearshore avian mortality.

Dabigatran (Pradaxa) Is Safe for Extended Venous Thromboembolism Prophylaxis After Surgery for Pancreatic Cancer.

Background: The American College of Chest Physicians and American Hepato-Pancreato-Biliary Association recommend using low-molecular-weight heparin for 28 days postoperatively for venous thromboembolism prophylaxis after cancer surgery. Dabigatran is a once daily oral anticoagulant that is FDA approved for venous thromboembolism prophylaxis after orthopedic surgery, uses fixed dosing, and has an antidote.

Methods: Patients undergoing surgery for malignant pancreatic tumors (neuroendocrine excluded) from January 2017 to January 2018 were converted to dabigatran 220 mg daily on discharge until postoperative day 28; patients with medical or insurance contraindications were converted to enoxaparin or another direct oral anticoagulant.

Risk assessment of water quality in three North Carolina, USA, streams supporting federally endangered freshwater mussels (Unionidae).

Water quality data were collected from three drainages supporting the endangered Carolina heelsplitter (Lasmigona decorata) and dwarf wedgemussel (Alasmidonta heterodon) to determine the potential for impaired water quality to limit the recovery of these freshwater mussels in North Carolina, USA. Total recoverable copper, total residual chlorine, and total ammonia nitrogen were measured every two months for approximately a year at sites bracketing wastewater sources and mussel habitat. These data and state monitoring datasets were compared with ecological screening values, including estimates of chemical concentrations likely to be protective of mussels, and federal ambient water quality criteria to assess site risks following a hazard quotient approach.
