PURPOSE: The purpose of this study was to evaluate left ventricular (LV) deformation and LV dyssynchrony in patients with Wolff-Parkinson-White (WPW) syndrome and to identify the factors that affect the efficacy of radiofrequency catheter ablation (RFCA). METHODS: Thirty patients (26 men, mean age 40 ± 12 years) with WPW syndrome were prospectively recruited for this study. They underwent 2-dimensional transthoracic echocardiography with speckle tracking analysis before RFCA and again within 48 hours after RFCA...

PURPOSE OF REVIEW: The purpose of this paper is to provide recent insights in management of neurologic complications of left-sided infective endocarditis (IE). RECENT FINDINGS: Cerebral lesions observed in IE patients are thought to involve synergistic pathophysiological mechanisms including thromboembolism, sepsis, meningitis, and small-vessel cerebral vasculitis. Brain MRI represents a major tool for the detection of asymptomatic events occurring in the majority of patients...

BACKGROUND: A decision-to-delivery interval (DDI) of no more than 20 minutes has long been considered a requirement for cesarean sections, even though there have hardly been any studies on this topic. We retrospectively investigated data relevant to DDI for emergency cesarean sections performed for the most common indications, namely, suspected and documented fetal asphyxia. METHODS: We analyzed data on emergency in-hospital cesarean sections in the period 2008-2015...

OBJECTIVE: Autoimmune polyendocrine syndrome type 1 (APS-1) is a rare, childhood onset disease caused by mutations in the autoimmune regulator (AIRE) gene. Chronic mucocutaneous candidiasis (CMC) is one of the three major disease components and is, to date, mainly explained by the presence of neutralizing auto-antibodies against cytokines [interleukin (IL)-17A, IL-17F, and IL-22] from T helper 17 cells, which are critical for the protection against fungal infections. However, patients without current auto-antibodies also present CMC and we, therefore, hypothesized that other immune mechanisms contribute to CMC in APS-1...

Ebstein's anomaly is a rare congenital heart disorder, accounting for <1% of all cases of congenital heart disease. It is a congenital malformation of the heart that is characterized by apical displacement of the septal and posterior tricuspid valve leaflets, leading to atrialization of the right ventricle with a variable degree of malformation and displacement of the anterior leaflet. We report the case of a 25 years old female with Ebstein's anomaly which was associated with Ostium Secundum type of atrial septal defect and WPW syndrome, who presented with dyspnea, palpitations, cyanosis, clubbing and cardiomegaly...

BACKGROUND: Mutations in the PRKAG2 gene encoding the γ-subunit of adenosine monophosphate-kinase (AMPK) cause hypertrophic cardiomyopathy (HCM) and familial-Wolff-Parkinson-White syndrome (WPW). Patients carrying the R302Q mutation in PRKAG2 present sinus bradycardia, escape rhythms, ventricular pre-excitation, supraventricular tachycardia and atrioventricular block. This mutation affects AMPK activity and increases glycogen storage in cardiomyocytes. The link between glycogen storage, WPW, HCM and arrhythmias remains unknown...

Context: Autoimmune polyendocrine syndrome type 1 (APS-1) is a rare monogenic autoimmune disease caused by mutations in the autoimmune regulator (AIRE) gene and characterized by chronic mucocutaneous candidiasis, hypoparathyroidism, and primary adrenal insufficiency. Comprehensive characterizations of large patient cohorts are rare. Objective: To perform an extensive clinical, immunological, and genetic characterization of a large nationwide Russian APS-1 cohort...

OBJECTIVES: The aim of this study was to examine tumor-infiltrating lymphocytes (TILs) and their prognostic value in patients with pancreatic ductal adenocarcinoma (PDAC) after neoadjuvant therapy. METHODS: Intratumoral CD4, CD8, and FOXP3 lymphocytes were examined by immunohistochemistry using a computer-assisted quantitative analysis in 136 PDAC patients who received neoadjuvant therapy and pancreaticoduodenectomy. The results were correlated with clinicopathological parameters and survival...

BACKGROUND: Wolff-Parkinson-White (WPW) syndrome and idiopathic left ventricular tachycardia (ILVT) are rare and up to now the coexistence of both entities has rarely been reported. In patients with ventricular preexcitation the underlying mechanism of paroxysmal tachycardia most likely is atrioventricular reentrant tachycardia (AVRT). However, without ECG documentation of the tachycardia diagnosis of the underlying mechanism cannot be made due to similar clinical presentation of AVRT and ILVT...

CONTEXT: Restless legs syndrome (RLS) is a common neurological disorder characterized by an irresistible urge to move the lower limbs often accompanied by unpleasant sensations in the legs, worsened at rest and in the evening. Symptoms are improved by movement. Its pathophysiology remains poorly understood. Lesion-related RLS has been reported, mainly in cases of stroke-related RLS involving the brainstem and lenticulostriate nuclei. Only few data of RLS in a context of spinal cord injury have been reported...

Short-chain fatty acids (SCFAs), which are generated by the bacterial fermentation of dietary fibers, promote expansion of regulatory T cells (Tregs). Potential therapeutic value of SCFAs has been recently highlighted in the experimental models of T cell-mediated autoimmunity and allergic inflammation. These studies suggest that physiological intestinal concentrations of SCFAs within the millimolar range are crucial for dampening inflammation-mediated processes. Here, we describe opposing effects of SCFAs on T cell-mediated immune responses...

Hanseniaspora uvarum (anamorph Kloeckera apiculata) is a predominant yeast on wine grapes and other fruits and has a strong influence on wine quality, even when Saccharomyces cerevisiae starter cultures are employed. In this work we sequenced and annotated approximately 93% of the H. uvarum genome. Southern and synteny analyses were employed to construct a map of the seven chromosomes present in a type strain. Comparative determinations of specific enzyme activities within the fermentative pathway in H. uvarum and S...

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of hospitalizations. Interventional studies focusing on the hospital-to-home transition for COPD patients are few. In the BREATHE (Better Respiratory Education and Treatment Help Empower) study, we developed and tested a patient and family-centered transitional care program that helps prepare hospitalized COPD patients and their family caregivers to manage COPD at home. METHODS: In the study's initial phase, we co-developed the BREATHE transitional care program with COPD patients, family-caregivers, and stakeholders...

The chorioallantoic membrane of fertilized chicken eggs in an early phase of breeding presents an approved test situation for the growth and treatment of human cancer cells.These models work due to the inoculation of cells into the membrane that stays within the egg shell during the time of investigation. In this study a modification of this model is presented. Samples of native tumors, rather than cell lines, are transplanted into the membrane and the body of the egg is taken out of the shell and placed in a plastic bowl...

Addressing how neural circuits underlie behavior is routinely done by measuring electrical activity from single neurons in experimental sessions. While such recordings yield snapshots of neural dynamics during specified tasks, they are ill-suited for tracking single-unit activity over longer timescales relevant for most developmental and learning processes, or for capturing neural dynamics across different behavioral states. Here we describe an automated platform for continuous long-term recordings of neural activity and behavior in freely moving rodents...

The 2016 Colorado Trail Race (CTR) was an ultra-endurance mountain bike race where competitors cycled for up to 24 hrs/day between altitudes of 1675 to 4025 meters to complete 800 kilometers and 21,000 meters of elevation gain. In one athlete, we had the unique opportunity to characterize skeletal muscle protein synthesis and mitochondrial respiration in response to a normal activity control period (CON) and the CTR. We hypothesized that mitochondrial protein synthesis would be elevated and mitochondrial respiration would be maintained during the extreme stresses of the CTR...
