The number of grafts and the use of the heart lung machine were not correlated with mortality, but intra-aortic balloon pump, the use of blood products and catecholamine intra-operatively were significant predictors. Post- operatively, agitation, post-operative stroke, atrial fibrillation and reintubation were bad prognosis factors. Surgical treatment of left main coronary artery stenosis has been the gold standard for the management of left main coronary disease. Nevertheless, patients should be well selected, in terms of their conditions, in order to benefit from surgical treatment. Introduction Despite the recent advances in medical treatment and percutaneous intervention techniques, surgical management of left main coronary artery disease remains the gold standard and drug-eluting stents have not been established yet to be more efficient and safe, especially in high risk patients with severe coronary lesions [1]. However, predictors of post-operative mortality must be assessed in order to achieve better results. Through our practice, in a single cardio-thoracic department in Tunisia, we aimed to assess the predictors of mortality after surgical management of left main coronary artery disease. Material and methods We reported our single center retrospective series about 148 patients who had undergone a coronary artery bypass grafting for left main coronary artery disease in the department of thoracic and cardio-vascular surgery of Abderrahmen Mami hospital in Tunisia from January 2004 to December 2012. The records of all our patients were reviewed and the predictors of post-operative mortality were assessed. Results During 9 years, 148 patients had been operated for left main coronary artery disease with a mortality Medimond. This rate was variable along the years with a tendency for decrease in the last three years to reach 10. History of diabetes was found in 50% of patients, chronic obstructive pneumonia in 14. Left ventricular ejection fraction was variable in our patients from 18 to 81% with a mean of 51%. Most of our patients had a multi-vessel disease and therefore a triple or more coronary artery bypass grafting was performed in 66. The number of grafts and the use of the heart lung machine were not correlated with mortality, but the use of intra-aortic balloon pump, blood products and catecholamine intra-operatively were significant predictors. Post-operatively, agitation, postoperative stroke, atrial fibrillation and reintubation were bad prognosis factors. From the early 70s, surgical management of patients with left main coronary artery disease has been proven to be the gold standard [5], with a continuing decrease in mortality rate, which varies between 2 and 3% according to a recent review [2]. Predictors of post-operative mortality have been assessed in many studies, in order to improve the post- operative outcomes and adapt the best strategy of revascularization according to the patients conditions. Chronic renal failure and previous congestive heart failure were specific risk factors for death after percutaneous intervention [6]. In our series, age was a predictive factor of post-operative mortality with patients 40 years being at high risk. Euroscore didnt show statistical significance in determining in-hospital mortality rate. Pre-operative atrial fibrillation and the use of catecholamine were positively correlated with post-operative death. Left ventricular dysfunction, right coronary artery stenosis and comorbidities such as diabetes didnt show significant impact on mortality. The same results were noticed in our series, with recent myocardial infarction being an important predictor of post-operative mortality. Intra-aortic balloon pump, inotropic support and the use of blood products intra-operatively were also significant predictors. Conclusion Surgical treatment of left main coronary artery stenosis remains the gold standard for the management of left main coronary artery disease.

Clinic of Anesthesiology Introducton The coronary artery fistula frequency among all coronary angiography patients is 0. Among them, the fistulisation of the coronary artery with the pulmonary artery and the right ventricle has been shown for 10-25 %. But the involvement of both the pulmonary artery and the right ventricle is a very seldom seen clinical antity (1, 2). Patients may complain about chest pain, syncope or signs of heart failure, while most of them can be asymptomatic. Our case report is about the ligation of such a fistula of a patient just complaining sometimes about chest pain, by a off-pump technique. Keywords: coronary artery fistula, off pump, ligation Case Report We report a 53 year old male patient who admitted to our clinic with rarely occuring chest pain, palpitation and dyspnea. After aorta and right ventricle sutures were taken the proximal and distal portions of the fistula were oblitered by 5/0 prolene sutures with a previously prepared teflon felt. Dscusson Coronary artery fistula is seen very rare among coronary artery abnormalities. Although showing symptoms like angina pectoris, dyspnea and signs of heart failure, some patients may remain asymptomatic. Sometimes it is detected incidentallly in coronary angiograms done due to other indications. The physical examination revealed a soft murmur in the left 2nd intercostal space and the diagnosis was completed with coronary angiography. The surgical indications for coronary artery fistulas are; symptomatic disease, aneurismatic coronary artery, signs of heart failure and ischemia.

This study was approved by the animal welfare sub-committee of Nara Institute of Science and Technology buy cheapest viagra professional and viagra professional. Mice were sacrificed by overdose intra peritoneal injection of sodium pentobarbital and perfusion fixated 100mg viagra professional mastercard. Since mouse aorta is around 500 1 discount viagra professional 100 mg on-line,000 m in diameter and expresses HtrA1, we then examined the aorta. Female mice showed more severe phenotypes probably because they are more susceptible [8] to atherosclerosis than male mice. Intimal hyperplasia or intimal proliferation develops after vessel wall injury or stress and it is one of the initial events in atherosclerosis. The aortic intima of mice at age 38-42 weeks did not show significant phenotype, but local intimal proliferation was found in the aorta of 52 weeks old mice. But the problem is, that leg amputation in atherosclerotic occluded disease is associated with acute mortality of about 20 to 30% and within the first year nearly 20% died (3, 4). A new treatment is the intramuscular or intraarterial injection of regenerative autologous stem cells e. In this open study, patients were recruited with leg pain at rest, non-healing ulcer and not suiteable for endovascular or surgical revascularisation procedures. Further studies from 2002 to 2012 with bone marrow- derived cells support the positive trend of salvage of threatened distal limbs. Recently, a closed bedside centrifugation system for processing whole bone marrow blood samples have been developed and employed in clinical trials. Bone marrow seems to be the cell source of choice, because puncture of iliac crest is possible under mild sedation, and yields reproducable cell numbers. Interestingly, the intraarterial cell application was performed either by an angiographic guiding catheter directely into the occluded/ stenotic peripheral artery or transcutaneously by selective syringe injection e. At the beginning of stem cell therapy in peripheral artery disease safety issues were thoroughly explored. Thereafter, stem cell application in humans with progressive peripheral artery disease was possible. No local or distant tumor growth, uncontrolled vascularisation, systemic inflammation, unexpected mortality rate or increased amputation free survival were observed. If medical treatment and revascularistation procedures fail or will not be applicable, limb amputation and death impend. Positive results on clinical symptoms, ischemia-associated outcome parameters and some endpoints like limb salvage has been demonstrated in several studies. However, lager randomised placebo-controlled double blind trials are necessary and are nowadays underway.

Autologous bone marrow cell transplantation increases leg perfusion and reduces amputations in patients with advanced critical limb ischemia due to peripheral artery disease. Materials and Methods Adipose tissue Adipose tissue samples were resected from 5 human subjects during plastic surgery (all females, age, 20-60 years) as excess discards. The protocol was approved by the Review Board for Human Research of Kobe University Graduate School of Medicine, Osaka University Graduate School of Medicine and Foundation for Biomedical Research and Innovation. Red blood cells were excluded using density gradient centrifugation with Lymphoprep (d=1. Following incubation, the adherent cells were washed extensively and then treated with 0. Animal model of myocardial infarction and cell transplantation 1 Chronic myocardial infarction swine models were prepared as described previously. From 5 days before cell transplantation to the end of the experiment, the swine received CyA as an immunosuppressant (6. The studies were shown as M-mode with short axis view observed from left 5th intracostal space. For histological analysis, the swine hearts were dissected out at the end of the experiment and immediately fixed overnight in 4% paraformaldehyde, and applied for embedding in paraffin wax. The sections were cut at 3-m thickness, and then incubated with mouse monoclonal antibodies to human alpha-cardiac actin (American Research Products. The stained all slides were viewed on a BioZero laser scanning microscope (Keyence, Osaka, Japan). After incubation with spermine for indicated time, the cells showed the increment of cardiocytic marker-expressions. First, the source of adipose-derived cells is easily and safely accessible and large quantities of the cells can be obtained without serious ethical issues. Finally, the reconstruction of a thick myocardial wall rescued cardiac dysfunction after chronic myocardial infarction. For adipogenic differentiation, cells were cultured in Differentiation Medium (Zen-Bio, Inc. After three days, half of the medium was changed with Adipocyte Medium (Zen-Bio) every two days. Five days after differentiation, adipocytes were characterized by microscopic observation of intracellular lipid droplets by Oil Red O staining. For Alcian Blue staining, nuclear counter- staining with Weigerts hematoxylin was followed by 0. The immunosuppression regimen consisted of the following: i) intramuscular injection of cyclosporin A (6 mg/kg/day) daily from the day before surgery to sacrifice, ii) intramuscular injection of rapamycin (0. Serum samples were obtained from nonfasting rabbits before and after transplantation. Serum total cholesterol was measured in each sample using assay kits from Wako Pure Chemical Industries (Osaka, Japan). Significant reductions in total serum cholesterol were observed within 4 weeks of the transplantation, and the reductions were maintained for the entire period. The source of stem cells for such therapy should be easily and safely accessible, free of any ethical issue, and when possible, available in large amounts. Adipose tissue is considered a suitable cell source as mentioned above; because it is abundant and Medimond. The procedure used for obtaining cells from 7 lipoaspirates is somewhat similar to that described by Bjorntorp et al.

Condition specific registers are essential for data collection on complex conditions when definitions need to be standardized and completeness ensured. Cases of congenital anomaly among livebirths, stillbirths, fetal deaths from 20 weeks gestation, and terminations of pregnancy after prenatal diagnosis of any gestation are registered. More information about the networks activities, its publications as well as data tables on the prevalence of congenital anomalies in Europe is available on its website www. Maternal demographic characteristics affect rates of perinatal mortality and morbidity [20]. The literature shows that older mothers and nulliparas both face increased risks of stillbirth [21-23] Studies report higher rates of antepartum, intrapartum and neonatal complications such as pregnancy induced hypertension, preterm labor, caesarean births and neonatal intensive care unit admissions in older women [24-26]. Multiple pregnancies also carry a much higher fetal and neonatal mortality risk than singleton pregnancies [30-32]. This increased risk is mostly due to the higher preterm birth rate in multiple pregnancies [33, 34]. Numerous reports have demonstrated the harmful effects of smoking on maternal and neonatal condition [35-37]. These effects concern not only the perinatal period but also the infants long-term development. Smoking cessation may be the most effective intervention to improve both short- and long-term outcome for mothers and children and is an indicator of effective antenatal preventive health services. Finally, a large body of literature has consistently documented differences in perinatal health outcomes linked to social factors [38, 39]. Mortality and morbidity rates are higher among 165 socially disadvantaged population groups, defined with respect to individual indicators of social status such as education or parental occupation and neighborhood deprivation scores. Parity may not always be defined in the same way, since the rules about counting past stillbirths or early abortions and births from previous marriages differ. In contrast, data on smoking during pregnancy and maternal education are less frequently collected in routine statistics. However, these items are included in many birth registers and thus can be considered realistic goals for routine health reporting. Country of birth is also collected in many registers and in vital statistics, but common conventions for reporting on these data do not as yet exist. The relationship of maternal age to perinatal health outcomes is U-shaped and it is thus pertinent to compare the extremes of the age distribution. For young mothers the increased risks of perinatal mortality are associated with social and health care factors, including lack on antenatal care, unwanted or hidden pregnancies, poor nutrition and lower social status [40]. Differences between the new and old member states are also apparent with respect to childbearing at older ages. There is a trend towards later childbearing in the 15 old member states, while this trend is much less evident in the new member states. Smoking among women of childbearing age varies substantially across Europe from 15 to over 40%. Failure to collect these data at a national level in many countries may prevent the generalisation of smoking cessation programmes for pregnant women and will certainly preclude the measurement of their effects. Preterm birth and low birth weight are important risk factors for morbidity in infancy and childhood. Changes in antenatal and delivery care have reduced morbidity from intra partum asphyxia and dystocia among babies born at term. An indicator that specifically monitors neonatal health outcomes among babies at highest risk is also considered a priority for development. For example, changes in birth notification and registration practices can cause major changes in these rates. In France in 2001, the registration of stillbirths was reduced from 28 to 22 weeks and fetal mortality rates rose from 6 to over 9 per 1000 [48]. Fetal and neonatal mortality should be presented by gestational age or birth weight groups in order to improve the interpretation and reliability of these data by making it possible to separate out the groups, such as extremely low birth weight babies, for which comparability between countries is questionable. Each country, however, has its own classification system for analysing and reporting these data. These differences in classification systems mean that it is not possible to produce a comparative table of causes of death. Morbidity indicators also require more collaborative work before they can be used for international comparisons. Similar data is probably available in other countries, but not presently accessed. More research on the quality of hospital discharge data is necessary before this indicator can be reported on a European level. Table 2 presents data on mortality rates for 2005 or most recent year and illustrates the large variation that exists between countries in Europe. Similar disparities are observed for mortality in the first year of life (from 2 to 15 per 1,000), as well as for fetal mortality (from 2 to 8 per 1,000). If every country had the mortality of those with the lowest rates, this number would be halved. There are marked differences in rates of neonatal mortality between countries based on their date of accession to the European Union. Among countries who joined prior to 2004 (the original 15 members) and Norway, the median rate of neonatal mortality in 2004 was 2. These babies include those that are preterm, with normal or low birthweights and babies born at term with growth restriction; all these groups are at higher risk of having longer-term impairments in childhood than term babies with normal birthweight. Data on preterm babies are not currently reported routinely, but this information is very important for evaluating perinatal health outcomes. However even babies born between 33 and 35 weeks of gestation, often termed mildly or moderately preterm births, have higher mortality and are more likely than others to have motor and learning difficulties than term babies [52-54]. Committees that audit maternal deaths regularly report that 40-60% of them are associated with substandard care [57-59].
