We report a case of isolated native tricuspid valve infective endocarditis caused by Coagulase Negative Staphylococcus in a non-IV drug abuser without structural heart disease. Early diagnosis and prompt initiation of appropriate treatment saved the patient without surgical intervention. The recent trend of Coagulase Negative Staphylococci (CoNS) causing native valve endocarditis (NVE) is reviewed with literature.

Interferons have attracted considerable attention due to their vital roles in the host immune response and low induction of antibiotic resistance. In this study, total RNA was extracted from spleen cells of chicken embryos inoculated with Newcastle disease vaccine, and the full-length chicken interferon-γ (ChIFN-γ) gene was amplified by RT-PCR. The full complementary DNA sequence of the ChIFN-γ gene was 495 bp long and was cloned into the prokaryotic expression vector pProEX™HTb . The plasmid was transformed into Escherichia coli DH5α and the expression of ChIFN-γ was induced by isopropyl β-D-1-thiogalactopyranoside...

Stress hyperglycemia is commonly observed in patients suffering from ischemic heart disease. It not only worsens cardiovascular prognosis but also attenuates the efficacies of various cardioprotective agents. This study aimed to investigate the protective effect of melatonin against myocardial ischemia-reperfusion (MI/R) injury in acute hyperglycemic state with a focus on Notch1/Hes1/Akt signaling and intracellular thioredoxin (Trx) system. Sprague-Dawley rats were subjected to MI/R surgery and high glucose (HG, 500 g/L) infusion (4 ml/kg/h) to induce temporary hyperglycemia...

Little is known about how the virulence of a human pathogen varies in the environment it shares with its vector. This study focused on whether the virulence of Trypanosoma cruzi (Trypanosomatida: Trypanosomatidae), the causal agent of Chagas' disease, is related to altitude. Accordingly, Triatoma dimidiata (Hemiptera: Reduviidae) specimens were collected at three different altitudes (300, 700 and 1400 m a.s.l.) in Chiapas, Mexico. The parasite was then isolated to infect uninfected T. dimidiata from the same altitudes, as well as female CD-1 mice...

We report the case of a 67-year-old woman with a carcinoid tumor of midgut origin who developed carcinoid heart disease and died because of bowel perforation. Echocardiography allowed the diagnosis, recognizing the typical abnormalities of tricuspid and pulmonary valve leaflets. The sonographic examination also evidenced peculiar alterations of the right heart hemodynamics: end-diastolic reversal of flow at the level of the pulmonary valve, reduced respiratory excursion without enlargement of the inferior vena cava, and biphasic hepatic venous flow without respiratory variation...

It has been established that cell-free DNA circulating in the bloodstream affects cells. The characteristics of cfDNA depend on the physiological state of the organism. As we showed previously, diseases can cause either GC-enrichment of the cell-free DNA pool or its oxidation. Thus, in cases of cerebral atherosclerosis, heart attack and rheumatic arthritis the cell-free DNA pool is GC-enriched and, in the case of cancer, both GC-enriched and oxidized. Herein we investigated the time-dependent effect of oxidized and GC-rich cell-free DNA on NF-kB and NRF2 signaling pathways in human mesenchymal stem cells and showed that they affect cells in different ways...

BACKGROUND: Cross-sectional studies suggest many people are unaware that cancer risk increases with age, but this misbelief has rarely been studied prospectively, nor are its moderators known. PURPOSE: To assess whether people recognize that cancer risk increases with age and whether beliefs differ according to gender, education, smoking status, and family history of cancer. METHODS: First, items from the cross-sectional Health Information National Trends Survey (n = 2069) were analyzed to examine the association of age and perceived cancer risk...

PURPOSE: Knowledge of how alterations in pharmacogenomics and pharmacogenetics may affect drug therapy in the intensive care unit (ICU) has received little study. We review the clinically relevant application of pharmacogenetics and pharmacogenomics to drugs and conditions encountered in the ICU. SOURCE: We selected relevant literature to illustrate the important concepts contained within. PRINCIPAL FINDINGS: Two main approaches have been used to identify genetic abnormalities - the candidate gene approach and the genome-wide approach...

Ivabradine is a blocker of the funny current channels in the sinoatrial node cells. This results in pure heart rate reduction when elevated without direct effect on contractility or on the vessels. It was tested in a large outcome clinical trial in stable chronic heart failure (CHF) with low ejection fraction, in sinus rhythm, on a contemporary background therapy including betablockers (SHIFT: Systolic Heart Failure Treatment with the If inhibitor Trial).The primary composite endpoint (cardiovascular mortality or heart failure hospitalization) was reduced by 18% whereas the first occurrence of heart failure hospitalizations was reduced by 26%...

Heart failure and depression are widespread diseases and of particular clinical and economic relevance. Compared with the general population depression is up to 5‑times more common in patients with heart failure, with adverse effects on morbidity, mortality, quality of life and treatment costs. Depressive symptoms overlap with those of heart failure which renders diagnosis difficult. Simple screening tools, e. g. the two-item patient health questionnaire, help to recognize depression in the clinical routine...

5-Fluorouracil (5-FU) is the backbone of the chemotherapy regimens approved for treatment of many malignancies, especially colorectal cancer (CRC). The incidence of cardiotoxicity associated with 5-FU ranges between 1.5% to 18% and is most commonly manifested as anginal symptoms. Cardiomyopathy is very rarely reported with 5-FU and capecitabine. A 35-year-old Caucasian male with T3, N1, M0 rectal cancer after the initial neoadjuvant chemoradiation with 5FU/LV followed by surgical abdominoperineal resection (APR), began mFOLFOX6 in the adjuvant setting...

Diagnosis of mitochondrial respiratory chain disorder (MRCD) is often difficult. Its pathogenesis is still unclear. We diagnosed MRCD by measuring the activity of the mitochondrial respiratory chain enzyme, and the patient also had hemophagocytic lymphohistiocytosis (HLH). A preterm female infant was born at 34 weeks of gestation. On day 6, HLH was revealed by bone marrow aspiration. She died on day 10 due to uncontrollable HLH. An autopsy was performed, and we measured the activity of the mitochondrial respiratory chain enzyme in the liver, muscle, and heart...

Idiopathic inflammatory myopathies (IIM) include the main subgroups polymyositis (PM), dermatomyositis (DM), inclusion body myositis (IBM) and juvenile DM (JDM). The mentioned subgroups are characterised by inflammation of skeletal muscles leading to muscle weakness and other organs can also be affected as well. Even though clinically significant heart involvement is uncommon, heart disease is one of the major causes of death in IIM. Recent studies show an increased prevalence of traditional cardiovascular risk factors in JDM and DM/PM, which need attention...

In the modern era, with high-throughput technology and large data size, associational studies are actively being generated. Some have statistical and clinical validity and utility, or at least have biologically plausible relationships, while others may not. Recently, the potential effect of birth month on lifetime disease risks has been studied in a phenome-wide model. We evaluated the associations between birth month and 5 cardiovascular disease-related outcomes in an independent registry of 8,346 patients from Ontario, Canada in 1977-2014...
