Holobiont nitrogen control and its potential for eutrophication resistance in an obligate photosymbiotic jellyfish.

Background: Marine holobionts depend on microbial members for health and nutrient cycling. This is particularly evident in cnidarian-algae symbioses that facilitate energy and nutrient acquisition. However, this partnership is highly sensitive to environmental change-including eutrophication-that causes dysbiosis and contributes to global coral reef decline.

Reasons for discontinuation of acute postoperative pain ketamine infusions: A retrospective case-control study.

Purpose: The purpose of the study was to investigate factors associated with early discontinuation of low-dose ketamine infusions due to adverse drug events (ADEs).

Methods: A retrospective, matched case-control study of surgical patients who received low-dose ketamine infusions for postoperative pain over 6 years was conducted. Forty-seven study patients, who required early discontinuation of their infusion due to ADEs, were included and matched 1:1 with 47 controls, who did not experience ADEs, for a total of 94 patients.

Improving Disaster Response Efforts Through the Development of a Disaster Health Care Response System.

We review the development of a disaster health care response system in Mississippi aimed at improving disaster response efforts. Large-scale disasters generate many injured and ill patients, which causes a significant utilization of emergency health care services and often requires external support to meet clinical needs. Disaster health care services require a solid infrastructure of coordination and collaboration to be effective.

Treatment of accidental perianal injection of topical thrombin with intravenous antithrombin.

While topical thrombin application can markedly improve surgical hemostasis, rapid absorption of thrombin can result in pulmonary embolism and death. We report a case of accidental interstitial infiltration of topical thrombin after hemorrhoidectomy that was treated with administration of human antithrombin and heparin anticoagulation. Except for a marked decrease in antithrombin activity from super normal to normal values, the patient exhibited no laboratory or clinical signs of pulmonary embolism, thrombin mediated consumptive loss of procoagulants, or regional thrombosis.
