B.C. Teachers’ Federation president Jim Iker says members voted Monday and Tuesday, and will be asked to endorse additional job action up to, and including, a strike that would shut down every public school in the province.Iker says the stronger tactics were being considered even before yesterday’s Labour Relations Board ruling went against the union and allowed the government to dock teachers’ and impose a partial lockout.Iker goes on to say if teachers walk off the job, “schools will be closed and there will be no instructions or any other activities”, the press reports. – Advertisement -The union dropped its wage demand on Tuesday by one per cent, bringing the request into the range of 12 per cent over four years, but the employer has been offering 7.3 per cent over six years. If a full scale strike is approved, teachers must give three-days notice, meaning the earliest date for a walkout would be Monday, June 16th.

Gammie, MD, from the University of Maryland School of Medicine in Baltimore. “In these cases, the malfunctioning mitral valve has caused significant damage to the heart and/or lungs, and while an operation can be performed, long-term outcomes will be compromised, to some extent.”Dr. Gammie, Vinay Badhwar, MD, from West Virginia University in Morgantown, and colleagues analyzed data from The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) in order to determine trends related to current mitral valve operations in North America. The ACSD contains more than 6.5 million cardiac surgery procedure records, representing more than 90% of all adult cardiac surgery hospitals across the US and Canada.The researchers identified 87,214 patients at 1,125 centers who had isolated primary mitral valve operations from July 2011 to September 2016. The average age of patients in this group was 64 years; half were female. During the study period, the number of mitral valve operations performed per year increased by 24%, from 14,442 in 2011 to 17,907 in 2016, with a 44% increase in primary mitral operations performed for degenerative disease, the most common form of mitral valve disease in the United States.”This suggests that the mitral valve disease may have reached a chronic stage prior to referral for operation, which means that heart and lung damage may not be fully reversible,” explained Dr. Badhwar. “In these patients, their symptoms may improve after surgery, but their life expectancy may be reduced.”Related StoriesDon’t Miss the Blood-Brain Barrier Drug Delivery (B3DD) Summit this AugustNew research links “broken heart syndrome” to cancerDon’t ignore diastolic blood pressure values, say researchersThe mitral valve-;one of four valves in the heart-;is the inflow valve between the lungs and the main pumping chamber of the heart (the left ventricle). This valve allows blood to enter the heart from the lungs when the heart muscle is relaxing and also prevents backflow of blood when the heart squeezes. Mitral valve diseases include mitral regurgitation (leaking) and mitral stenosis (narrowing), which may cause fatigue and shortness of breath.”Once the leakage is severe, heart damage may result, thus mitral valve operation is recommended,” said Dr. Badhwar. “The preferred operation is mitral repair, whenever possible. If performed in a timely manner, the patient’s heart function and life expectancy may return to normal.”In this study, the data showed that the overall repair rate was 65.6% (57,244) and the replacement rate was 34.4% (29,970). Overall operative mortality was 2.0% (1,762).”We found that the number of operations performed for mitral valve disease is growing faster than any other category of heart operation and that the results were excellent with low risks of death and complications,” said Dr. Gammie.The researchers also revealed that while the prevalence of mitral valve disease and the number of mitral valve operations performed per year are increasing, overall aortic valve operations were performed 1.6 times more commonly than mitral valve operations during the study period.”This may suggest important under-referral and under-treatment of mitral valve disease, which may be related to the slower progression of signs and symptoms of mitral compared to aortic disease, as well as potential lack of adherence to guidelines for intervention,” said Dr. Gammie. “So although contemporary outcomes are excellent, there remains an important and substantial opportunity to improve results for patients with mitral valve disease by following established guidelines and encouraging earlier referral for operation.”
