Sleep is thought to be a learned neurological process that develops in response to cues from the environment. This is a process that we all go through, but which is impaired in children with neurodevelopmental problems. As a result they can retain their fragmented "baby" pattern of sleeping, potentially throughout their life. Circadian rhythm sleep disorders (CRSD) occur when there is a dissoci...

Surgical coronary bypass has evolved continually, and recent developments favor performing coronary grafts with all-arterial conduits in order to obtain better long-term graft patencies. With bilateral internal mammary artery grafts and both radial arteries, four excellent arterial conduits exist for revascularization of the majority of multivessel disease patients, including those with valve d...

OBJECTIVE To conduct a systematic review of the efficacy and safety of exogenous melatonin in managing secondary sleep disorders and sleep disorders accompanying sleep restriction, such as jet lag and shiftwork disorder. DATA SOURCES 13 electronic databases and reference lists of relevant reviews and included studies; Associated Professional Sleep Society abstracts (1999 to 2003). STUDY SEL...

background: we presumed that the surgeon himself has an impact on the results after coronary artery bypass grafting (cabg) as there is no unique protocol for the discharge of post-operative cardiac patients at our institution. therefore, we examined whether the surgeon himself has an impact on the intensive care unit (icu) stay of isolated cabg patients. methods: we prospectively studied a tota...

background: left ventricular dysfunction is one of the most powerful predictors of early and late outcomes in patients who undergo coronary artery bypass grafting (cabg). the aim of this study was to assess the early results of cabg that predict 30-day mortality and prolonged length of hospital stay (los) after cabg in patients with an ejection fraction (ef) of 30% or less. methods: seven hundr...

background: cardiac rehabilitation is known as a powerful non-pharmacological approach for improving functional capacity, and left ventricular systolic function; however, some limited data have suggested an attenuation of the decline in diastolic function with this program. this study investigated the effect of high intensity aerobic exercise following coronary artery bypass surgery (cabg) on d...

introduction: doppler ultrasonography (dus) is the most preferable method for screening of carotid artery disease in patients undergoing cabg. the purpose of this study was to investigate the frequency of carotid artery disease and determine the relation between known risk factors of atherosclerosis and rate of carotid artery narrowing in order to identify high-risk groups among patients schedu...

conclusions selenium can alleviate i/r injury in short time. further well-planned trials are needed to find the optimized administration method to achieve the most beneficial effects to the patients. background in patients with coronary artery stenosis, coronary artery bypass graft surgery (cabg) is the most effective strategy to limit infarct size and improving outcomes. however, the rapid res...

introduction: an attack of acute myocardial infarction (mi) poses the threat of great damage to cardiac tissue. operative therapeutic modalities such as coronary artery bypass grafting (cabg) may enhance myocardial perfusion in high-grade coronary vasculature occlusions. it has been shown previously that low-level laser therapy (lllt) significantly reduces infarct size following induction of my...
