Temporal Trends and Outcomes of Acute Myocardial Infarction in Patients With Cancer

Background: Data on outcomes of ST-elevation myocardial infarction (STEMI) in patients with cancer are scarce. We investigated the nationwide trends in admissions for STEMI, utilization of percutaneous coronary intervention (PCI), and in-hospital outcomes in patients with the three most common cancer diagnoses (lung, breast, and colon) compared to patients without cancer. Methods: We conducted an administrative database study using the Nationwide Inpatient Sample (NIS). All in-patient hospitalizations for STEMI from 2001 to 2011 were identified. Patients with concomitant diagnosis of lung, breast or colon cancer were identified using appropriate International classification of diagnosis (ICD 9-CM) codes. Primary outcome was utilization of PCI and in-hospital mortality in patients with cancer compared to those without cancer. Results: Utilization of PCI was 30.8% (1,191/3,871), 20.2% (4,541/22,480) and 17.3% (1,716/9,944) in patients with breast, lung and colon cancer, respectively. Among patients without any of these cancers, use of PCI was 49.6%. In-hospital mortality was highest in patients with lung cancer (57.1%) and lowest in patients without cancer (25.7%). Conclusions: Patients with cancer have significantly worse in-hospital mortality compared to those without cancer, partly due to a relatively lower rate of PCI utilization in cancer patients with STEMI

Spontaneous left main coronary artery dissection complicated by pseudoaneurysm formation in pregnancy: role of CT coronary angiography

We report a case of a 26-year-old female, who presented at 34 weeks of an uncomplicated pregnancy with an acute ST elevation anterior wall myocardial infarction. Cardiac catheterization suggested a left main coronary artery dissection with pseudoaneurysm formation. The patient's course was complicated by congestive heart failure. She was initially managed conservatively by a multidisciplinary team including heart failure specialists, obstetricians, and cardiovascular surgeons. 4 days after admission, her LMC was imaged by dual-source 64 slice Cardiac computed tomography, coronary dissection was identified extending to the lumen, and the presence of pseudoaneurysm was confirmed. She underwent subsequently a staged procedure, which included placement of an intra-aortic balloon pump, cesarean section, and coronary artery bypass grafting. This case illustrates the utility of coronary artery CT imaging to assess the complexity and stability of coronary artery dissections, thereby helping to determine the need for, and timing of revascularization procedures

Early farmers from across Europe directly descended from Neolithic Aegeans

Farming and sedentism first appeared in southwestern Asia during the early Holocene and later spread to neighboring regions, including Europe, along multiple dispersal routes. Conspicuous uncertainties remain about the relative roles of migration, cultural diffusion, and admixture with local foragers in the early Neolithization of Europe. Here we present paleogenomic data for five Neolithic individuals from northern Greece and northwestern Turkey spanning the time and region of the earliest spread of farming into Europe. We use a novel approach to recalibrate raw reads and call genotypes from ancient DNA and observe striking genetic similarity both among Aegean early farmers and with those from across Europe. Our study demonstrates a direct genetic link between Mediterranean and Central European early farmers and those of Greece and Anatolia, extending the European Neolithic migratory chain all the way back to southwestern Asia

Candidate genetic analysis of plasma high-density lipoprotein-cholesterol and severity of coronary atherosclerosis

<p>Abstract</p> <p>Background</p> <p>Plasma level of high-density lipoprotein-cholesterol (HDL-C), a heritable trait, is an important determinant of susceptibility to atherosclerosis. Non-synonymous and regulatory single nucleotide polymorphisms (SNPs) in genes implicated in HDL-C synthesis and metabolism are likely to influence plasma HDL-C, apolipoprotein A-I (apo A-I) levels and severity of coronary atherosclerosis.</p> <p>Methods</p> <p>We genotyped 784 unrelated Caucasian individuals from two sets of populations (Lipoprotein and Coronary Atherosclerosis Study- LCAS, N = 333 and TexGen, N = 451) for 94 SNPs in 42 candidate genes by 5' nuclease assays. We tested the distribution of the phenotypes by the Shapiro-Wilk normality test. We used Box-Cox regression to analyze associations of the non-normally distributed phenotypes (plasma HDL-C and apo A-I levels) with the genotypes. We included sex, age, body mass index (BMI), diabetes mellitus (DM), and cigarette smoking as covariates. We calculated the q values as indicators of the false positive discovery rate (FDR).</p> <p>Results</p> <p>Plasma HDL-C levels were associated with sex (higher in females), BMI (inversely), smoking (lower in smokers), DM (lower in those with DM) and SNPs in <it>APOA5, APOC2</it>, <it>CETP, LPL </it>and <it>LIPC </it>(each q ≤0.01). Likewise, plasma apo A-I levels, available in the LCAS subset, were associated with SNPs in <it>CETP</it>, <it>APOA5</it>, and <it>APOC2 </it>as well as with BMI, sex and age (all q values ≤0.03). The <it>APOA5 </it>variant S19W was also associated with minimal lumen diameter (MLD) of coronary atherosclerotic lesions, a quantitative index of severity of coronary atherosclerosis (q = 0.018); mean number of coronary artery occlusions (p = 0.034) at the baseline and progression of coronary atherosclerosis, as indicated by the loss of MLD.</p> <p>Conclusion</p> <p>Putatively functional variants of <it>APOA2</it>, <it>APOA5, APOC2</it>, <it>CETP, LPL</it>, <it>LIPC </it>and <it>SOAT2 </it>are independent genetic determinants of plasma HDL-C levels. The non-synonymous S19W SNP in <it>APOA5 </it>is also an independent determinant of plasma apo A-I level, severity of coronary atherosclerosis and its progression.</p

The effect of scolicidal solutions on the biliary tracts (An experimental study in rats) SKOLISIDAL AJANLARIN SAFRA YOLLARI UZERINE ETKISI (DENEYSEL CALISMA)

Several cases of sclerosing cholangitis have been reported after surgical treatment of hepatic hydatid disease. In these patients, hypertonic saline of formaldehyde solutions had been given into the cysts. In our country, 3% hydrogen peroxide has been frequently injected into the cyst as a scolicidal agent and there have been no reported case of sclerosing cholangitis. In this experimental study, we showed that injection of 20% hypertonic saline solution, 2% formaldehyde solution, 3% hydrogen peroxide solution and 10% hydrogen peroxide solution into the biliary tract in rats caused lesions of the biliary epithelium. As compared with 20% hypertonic saline solution, 2% formaldehyde solution and 3% H2O2 resulted in more severe lesions in the biliary epithelium and in addition, induced the development of periductal fibrosis and pseudocirrhosis. This experimental study confirms the deleterious effect of all scolicidal solutions to the biliary epithelium and the liver

Percutaneous Muscular Ventricular Septal Defect Closure with 2D Transthoracic Echocardiography: Can We Sufficiently Visualize It?

Ventricular septal defect (VSD) is one of the most common congenital heart diseases worldwide today. Although the majority close spontaneously, transcatheter VSD closure is a common option for symptomatic patients with suitable anatomy in adult age. Although transesophageal echocardiography (TEE) and intracardiac echocardiography are the most common imaging modalities for the procedure, in patients with poor TEE images, Transthoracic echocardiography (TTE) can be used as a reliable alternative. Here we present an adult patient with pulmonary hypertension associated with a muscular VSD which was closed percutaneously using 2-dimensional TTE because of poor TEE images
