The Minimum Spanning Tree (MST) problem is one of the most important and commonly occurring primitive in the design and operation of data and communication networks. While there are distributed algorithms for the MST problem these require relatively large number of messages and time, and are fairly involved, require synchronization and a lot of book keeping; this makes these algorithms impracti...

BACKGROUND Atherosclerosis of the coronary arteries is the most common cause of death in the United States for persons over the age of 45. Dyslipidemia is one of the risk factors for the development of coronary atherosclerosis. Recent studies suggest that treating dyslipidemia in persons with coronary atherosclerosis may decrease morbidity and mortality. METHODS A meta-analysis of 33 studies ...

IMPORTANCE The effectiveness of perioperative β-blockade in patients undergoing noncardiac surgery remains controversial. OBJECTIVE To determine the associations of early perioperative exposure to β-blockers with 30-day postoperative outcome in patients undergoing noncardiac surgery. DESIGN, SETTING, AND PATIENTS A retrospective cohort analysis evaluating exposure to β-blockers on the day o...

With interest we have read the paper of Kupczyk et al. It is an important contribution to the current understanding of the course and early detection of asthma exacerbations, especially with the advent of internet-based self-management programmes using daily or weekly monitoring. In the current research the authors found that the combination of a 20% decrease in peak expiratory flow (PEF) on 2 ...

BACKGROUND Helicobacter pylori infection is recognized as a major contributory factor to many diseases, but recommended eradication therapies demonstrated unsatisfactory eradication rates. Currently, some studies suggested that lactobacillus species have an inhibitory action on Helicobacter pylori both in vitro and in vivo. OBJECTIVE this meta-analysis broadly examined the efficacy of eradica...

BACKGROUND AND AIM Postpolypectomy haemorrhage (PPH) is a known adverse event that can occur following polypectomy, occurring in 0.3-6.1% of cases. Previous meta-analysis has included small polyps, which are less likely to bleed, and less amenable to some methods of mechanical haemostasis. No comprehensive cost-benefit analysis of this topic is available. The aim of this study was to perform a ...

INTRODUCTION Only limited information is available on cost efficacy of the various biological agents used to treat patients with rheumatoid arthritis with intolerance or for whom it would be inappropriate to continue treatment with conventional agents. We estimated the efficacy and treatment costs of monotherapy with biological agents in the treatment of this group of patients. METHODS Data f...

BACKGROUND The number needed to treat (NNT) is an absolute effect measure that has been used to assess beneficial and harmful effects of medical interventions. Several methods can be used to calculate NNTs, and they should be applied depending on the different study characteristics, such as the design and type of variable used to measure outcomes. Whether or not the most recommended methods hav...
