A Case of Late-Onset Gemcitabine Lung Toxicity
Gemcitabine is a chemotherapeutic agent used for the treatment of a number of malignancies. Although its major dose-limiting side effect is myelosuppression, many pulmonary toxicities have been described with its use. Severe pulmonary toxicity is rare, but symptoms tend to be rapid in onset and potentially deadly. The average time from initiation of chemotherapy to onset of symptoms is less than two months. The most effective therapy is steroid administration, the efficacy of which has been variable. In this report, we describe a unique case of gemcitabine pulmonary toxicity in a patient who did not experience symptoms of pulmonary dysfunction until after 1 year of treatment. Her symptoms did not improve rapidly with steroids, nor did she rapidly decompensate as has been frequently described. To our knowledge, this is one of the first reported descriptions of late-onset gemcitabine lung toxicity
Gemcitabine, cisplatin and methylprednisolone (GEM-P) is an effective salvage regimen in patients with relapsed and refractory lymphoma
There is currently no standard salvage chemotherapy regimen in relapsed and refractory lymphoma. Gemcitabine is a novel nucleoside analogue, which acts synergistically with cisplatin both in vitro and in clinical studies. We evaluated the combination of gemcitabine, cisplatin and methylprednisolone (GEM-P) in 41 heavily pretreated patients with relapsed and refractory Hodgkin's and non-Hodgkin's lymphoma. The best-achieved response rate (RR) was 79% (95% CI 64–91), with a complete RR of 21%. In patients with chemo-resistant disease, the RR was 63%. Myelosuppression was the main toxicity, the incidence of Grade 3 or 4 anaemia, neutropenia and thrombocytopenia was 17.1, 61.0 and 53.7% respectively. Only one patient had neutropenic sepsis and none of the patients suffered from haemorrhage. Grade 3 or 4 nonhaematological toxicity was minimal and stem cell mobilisation was not inhibited. GEM-P is an effective salvage regimen and its use prior to autologous stem cell transplant warrants further investigation
Behavior learning to predict using neural networks (NN): Towards a fast, cooperative and adversarial robot team (RoboCup)
Team Cooperation using Dual Dynamics
The design of autonomous mobile robots includes the design of team behaviors. We have extended the Dual Dynamics scheme for behavior design in order to let the designer specify team behavior. This approach comes with a tool suite for team behavior specification, simulation, and monitoring, and is used for the coordination of soccer playing robots
The VolksBot Concept – Rapid Prototyping for real-life Applications in Mobile Robotics (Das VolksBot Konzept – Ein Baukastensystem für anwendungsnahes Rapid-Prototyping mobiler Roboter)
Behavior engineering with "dual dynamics" models and design tools
Dual Dynamics (DD) is a mathematical model of a behavior control system for mobile autonomous robots. Behaviors are specified through differential equations; forming a global dynamical system made of behavior subsystems which interact in a number of ways. DD models can be directly compiled into executable code. The article (i) explains the model; (ii) sketches the Dual Dynamics Designer (DDD) environment that we use for the design; simulation; implementation and documentation; and (iii) illustrates our approach with the example of kicking a moving ball into a goal
