More importantly, workout had a positive influence on several procedures of heart work as well as general quality of life,’ Berry said in a university news release. UT researchers analyzed studies that included a lot more than 400 people who have pulmonary hypertension. Their review discovered that exercise is safe and can decrease pressure in the arteries and boost patients’ ability to exercise. However, people with pulmonary hypertension should not begin an exercise program without initial consulting their doctor, Berry said. He noted that a lot of patients in the analysis were in supervised exercise programs that had lower levels of strength than those typically prescribed for heart failure patients.Although Hindawi doesn’t let authors recommend reviewers because of their manuscripts, it made a decision to examine the peer-review information for manuscripts submitted in 2013 and 2014 for possible fraud. The peer-review procedure used in Hindawi’s journals depends mainly on the expertise of its editorial board members and the guest editors of special issues, who are in charge of supervising the review of submitted manuscripts.5 Because the peer reviewers selected by the guest editors weren’t subject to any kind of independent verification, editors themselves could undermine the process in much the same way that authors or third-party agencies have done somewhere else: by creating fake reviewer identities and addresses from which they submitted positive reviews endorsing publication.
