OBJECTIVE To review the literature systematically to determine whether initiation of beta blockade within 45 days prior to noncardiac surgery reduces 30-day cardiovascular morbidity and mortality rates. METHODS PubMed (up to April 2013), Embase (up to April 2013), Cochrane Central Register of Controlled Trials (up to March 2013), and conference abstracts (January 2011 to April 2013) were sear...

INTRODUCTION Carotid endarterectomy (CEA) is a standard treatment for the prevention of stroke and death in patients with significant stenosis of the internal carotid artery. Eversion endarterectomy is warranted in patients with symptoms of cerebral ischemia and the degree of stenosis of 70-99%. The same is suitable for treating a symptomatic carotid artery stenosis with contralateral stenosis ...

Within traditional clinical care, the postoperative recovery after pelvic/rectal surgery has been slow with high morbidity and long hospital stay. The enhanced recovery after surgery program is a multimodal approach to perioperative care designed to accelerate recovery and safely reduce hospital stay. This review will briefly summarize optimal perioperative care, before, during and after surger...

BACKGROUND Enhanced recovery after surgery (ERAS) protocols consist of a set of perioperative measures aimed at improving patient recovery and decreasing length of stay and postoperative complications. We assess the implementation and outcomes of an ERAS program for colorectal surgery. METHODS Single center observational study. Data were collected from consecutive patients undergoing open or ...

This meta-analysis aimed to compare the short- and long-term outcomes in patients undergoing combined coronary endarterectomy and coronary artery bypass grafting (CE + CABG) versus isolated CABG, and particularly to examine subgroup patients with high-risk profile and patients with diffuse disease in the left anterior descending artery (LAD).Studies published between January 1, 1970 and May 31,...

This review provides an overview of the present knowledge on the aspects of preoperative fasting with the assessment of the evidence quality. A systematic research was conducted in electronic databases in order to identify trials published between 1990 and 2014 concerning preoperative fasting, early resumption of oral intake and the effects of oral carbohydrate mixtures on gastric emptying and ...

An MI-group is an algebraic structure based on a generalization of the concept of a monoid that satisfies the cancellation laws and is endowed with an invertible anti-automorphism representing inversion. In this paper, a topology is defined on an MI-group $G$ under which $G$ is  a topological MI-group. Then we will identify open, discrete and compact MI-subgroups. The connected components of th...

A study of the development of the eye in the cinnamon mouse, homozygous for the gene for microphthalmia (mi), has shown that the microphthalmia is due to failure of secondary vitreous formation associated with a coloboma. The retina is dystrophic but there is a residual population of large ganglion cells and the optic nerve also contains ganglion cells. All these ganglion cells have cytoplasm s...
