Nycomed Announces FDA Filing For Daxas(R) In COPD
Nycomed announced the submission of a New Drug Application (NDA) to the US Food and Drug Administration (FDA) for Daxas® as a once-daily oral treatment for patients with symptomatic COPD.

Two pivotal 12-month studies showed positive effects on exacerbation rates and pulmonary function (FEV1). Two supporting six-month studies also confirmed the efficacy of Daxas when used with standard bronchodilator treatments. Full data from all four studies are to be published during 2009.

Predictive Role In Peptic Ulcer Played By Childhood Adversities
Helicobacter pylori, nonsteroidal anti-inflammatory drug use and smoking are the most important risk factors for peptic ulcer. Alcohol intake may also play a role in the development of gastric ulcers. Psychological stress may also have an impact on the onset and course of ulcer disease. However, very little is known as to whether childhood adversities involving financial problems, conflicts in the family, problems with alcohol, and matters of personal security are associated with peptic ulcer.

CFIA And USDA Revise Potato Cyst Nematode Guidelines

The Canadian Food Inspection Agency (CFIA) and the United States Department of Agriculture (USDA) today announced revised guidelines for potato cyst nematode (PCN) that will allow continued trade of seed potatoes between the two countries. While PCN does not pose a risk to human health, it is recognized internationally as a destructive plant pest of economic importance and, therefore, a quarantine pest for the United States and Canada. "This Government is committed to helping farmers prosper, including facilitating access to international markets," said Minister of Agriculture Gerry Ritz. "These revised guidelines will allow for the continued trade of seed potatoes between Canada and the United States." "The United States and Canada are committed to working together to limit the spread of potato cyst nematodes on both sides of the border," said U.S. Agriculture Secretary Tom Vilsack. "These revised guidelines will ensure abundant potatoes for consumers as well as viable markets for potato farmers." The PCN Guidelines describe the national survey of potato production for PCN in both Canada and the U.S. and now require increased soil sampling and testing from all fields where seed potatoes are produced for trade between the two countries. The guidelines also outline the measures that should be taken to manage a PCN detection and contain procedures for the subsequent removal of restrictions on land. Both Canada and the U.S. have worked closely with industry representatives in revising these guidelines and will continue to work with stakeholders to ensure specific requirements are met. Continually improving our survey strategies and enhancing the required measures when PCN is detected are key to preventing the spread of this pest while ensuring the continued trade of seed potatoes across the Canada-U.S. border.
