OBJECTIVES: Postoperative atrial fibrillation (POAF) remains a major risk after cardiac surgery. Twelve percent patients admitted to this unit postcardiac surgery experienced POAF, which led to hemodynamic instability, increased risk of stroke, and increased length of postoperative intensive care unit stay. Our aim was to decrease the incidence of POAF in the cardiothoracic intensive care unit by the end of April 2014. METHODS: Design-Retrospective data analysis...

A multilayer structure of TeO2/interdigital transducers (IDTs)/ZnO(112¯0)/Si(100) was proposed and investigated to achieve both high sensitivity and temperature-stability for bio-sensing applications. Dispersions of phase velocities, electromechanical coupling coefficients K(2), temperature coefficient of delay (TCD) and sensitivity in the multilayer structures were simulated as functions of normalized thicknesses of ZnO (hZnO/λ) and TeO2 (hTeO2/λ) films. The fundamental mode of Love mode (LM) - surface acoustic wave (SAW) shows a larger value of K(2) and higher sensitivity compared with those of the first mode...

Oral mucositis manifests as erythematous and ulcerative lesions of the oral mucosa. Among its various causes, cancer treatment (e.g., chemotherapy with or without radiation therapy) is one of the more well known. It has been widely mentioned that oxidative stress parameters such as lipid peroxidation levels increase during the cancer process. Glutathione is one of the major intracellular enzymes used to detoxify oxidant molecules; it exists in both a reduced and oxidized state. Reduced glutathione is used as a substrate to synthesize glutathione peroxidase...

Current reforms of mental health and substance abuse services (MHS) emphasize community-based care and the downsizing of psychiatric hospitals. Reductions in acute and semi-acute hospital beds are achieved through shortened stays or by avoiding hospitalization. Understanding the factors that drive the current inpatient treatment provision is essential. We investigated how the MHS service structure (diversity of services and balance of personnel resources) and indicators of service need (mental health index, education, single household, and alcohol sales) correlated with acute and semi-acute inpatient treatment provision...

JAKs, a key family of cytoplasmic tyrosine kinases acting as a requisite part in the signaling process of growth factors and cytokines, important for immunity responses and hematopoiesis have become attractive targets for a considerable number of immune, inflammatory and hematopoietic diseases. Moreover, the JAK signal system has drawn significant attention in recent years as therapeutic targets including JAKs, STATs and JAK/STAT signal pathway. Herein, we present a review of the JAK/STAT signal pathway, the structure, biological function, mechanism of the JAKs and STATs along with a summary of the up-to-date clinical or approved JAK inhibitors which are involved in the treatment of various kinds of tumors and other immunity indications...

Surgery for heart diseases during pregnancy, especially necessitating cardiopulmonary bypass, is believed to trigger maternal and fetal risks and should be performed only when medical therapy has been unsuccessful to alleviate the cardiac decompensation. A 33-year-old pregnant woman in her 33rd week of gestation was admitted to our hospital. She had rheumatic mitral valvular stenosis and had undergone mitral valve replacement (MVR) with a mechanical prosthesis 11 years earlier in another center. Echocardiography revealed a thrombotic mass obstructing the leaflets of the mechanical mitral valve...

Four screening assays aimed for rapid detection of carbapenemase production from Gram-negative bacterial isolates i.e. the Neo-Rapid CARB kit (Rosco Diagnostica A/S), the RAPIDEC CARBA NP test (BioMérieux SA), the β CARBA test (Bio-Rad Laboratories N.V) and a home-made electrochemical assay (BYG Carba test) were evaluated against a panel comprising 328 clinical isolates (Enterobacteriaceae [n= 198], nonfermentative Gram-negative bacilli [n = 130]) with previously characterized resistance mechanisms to carbapenems...

PURPOSE OF REVIEW: This review provides an update on the need, development status, and important next steps for advancing development of vaccines against sexually transmitted infections (STIs), including herpes simplex virus (HSV), Neisseria gonorrhoeae (gonorrhea), Chlamydia trachomatis (chlamydia), and Treponema pallidum (syphilis). RECENT FINDINGS: Global estimates suggest that more than a million STIs are acquired every day, and many new and emerging challenges to STI control highlight the critical need for development of new STI vaccines...

Owing to statin's immune modulatory, anti-inflammatory, antioxidant, antithrombotic and endothelial function actions, they are widely used in the critical care settings in diverse disease scenarios. We aim to explore the evidence to globalize the utilization of statins in the intensive care practice for different indications. We carried out a search of the PubMed, Cochrane and EMBASE databases up to January 2016. We included review articles, meta-analyses, and original trials on the effects of statin therapy in the intensive care unit (ICU) combining the following MESH terms: 'satins', 'intensive care, 'cardiac surgery', 'sepsis', 'acute respiratory distress syndrome' 'pneumonia', subarachnoid hemorrhage', traumatic brain injury and 'critical illness'...

The title hydrated salt, C30H26N6(2+)·2C9H5N4O(-)·3H2O, was obtained as an unexpected product from the hydro-thermal reaction between potassium 1,1,3,3-tetra-cyano-2-eth-oxy-propenide, 4,4'-bi-pyridine and iron(II) sulfate hepta-hydrate. The cation lies across a twofold rotation axis in the space group I2/a with the other components all in general positions. In the cation, the H atom linking the pyridine units is disordered over two adjacent sites having occupancies of 0.66 (4) and 0.36 (4), i.e. as N-H⋯N and N⋯H-N...

This study investigated the impact of voluntary exercise on depressive behaviours, serum and hippocampal levels of myokines, and histopathological features of hippocampal formation in rats. Depressed rats were allowed to voluntarily run on a wheel for 3 weeks. Locomotor activity was assessed by a forced swimming test and the myokine levels in sera and hippocampal homogenates were measured using Enzyme-linked Immunosorbent Assay. Brain sections were analysed for hippocampal structure and neuronal counts. Voluntary running produced significant increase in the distance moved by rats and significant decrease in immobility duration...

N-Acetylglucosamine β-O-linked to nucleocytoplasmic proteins (O-GlcNAc) is implicated in the regulation of gene expression in organisms, from humans to Drosophila melanogaster. Within Drosophila, O-GlcNAc transferase (OGT) is one of the Polycomb group proteins (PcGs) that act through Polycomb group response elements (PREs) to silence homeotic (HOX) and other PcG target genes. Using Drosophila, we identify new O-GlcNAcylated PcG proteins and develop an antibody-free metabolic feeding approach to chemoselectively map genomic loci enriched in O-GlcNAc using next-generation sequencing...

Multiple sclerosis (MS) is an autoimmune disease in which auto-reactive T cells react with self-antigens expressed in the central nervous system (CNS). The main cause of MS is unknown. Nonetheless, the most probable theory is based on molecular mimicry, which suggests that some infections can activate T cells against brain auto-antigens like myelin proteolipid protein (PLP) and initiate the disease cascade. This study is conducted to evaluate the activatory effects of PLP58-74 on T lymphocytes and humoral immunity...

Lambl's excrescences are filamentous extensions of cardiac valves, mostly asymptomatic but rarely associated with catastrophic thromboembolic events such as acute ischemic stroke and acute coronary syndromes. Numerous case reports cited in the literature have addressed various spectrum of presentation of these syndromes and their outcomes based on therapies used. We encountered such a patient from our own experience who presented with an acute ischemic stroke with no other identifiable cause other than the Lambl's excrescences...

Carcinomatous lymphangitis accounts for 5% of all skin metastases, but blue lymphangitis of the breast has never been described. We report a case of blue lymphangitis of the breast in a patient 11 years after treatment for ipsilateral breast cancer that was in full remission. Breast examination and imaging showed no other abnormalities. Skin biopsy revealed a carcinomatous-pigmented infiltration corresponding to melanoma metastasis, which helped highlight a primitive right flank injury. This case report emphasizes that a full body exam should always be performed with unusual presentation of breast cancer and reiterates the indispensable place of histology before any diagnosis...
