Caries is the most common disease in the world. Great efforts have been undertaken for prevention and to identify a regenerative treatment solution for dental caries. Self-assembling β-sheet forming peptides have previously shown to form 3-dimensional fiber networks supporting tissue regeneration. In particular, the self-assembling peptide P11-4 has shown potential in the treatment and prevention of dental caries. It has previously been shown that application of monomeric P11-4 solution to early carious lesions can increase net mineral gain by forming de novo hydroxyapatite crystals...

Purpose There are limited data regarding the clinical use of decitabine for the treatment of acute myeloid leukemia in patients with a serum creatinine of 2 mg/dL or greater. Methods We retrospectively evaluated 111 patients with acute myeloid leukemia who had been treated with decitabine and compared the development of toxicities during cycle 1 in those with normal renal function (creatinine clearance greater than or equal to 60 mL/min) to those with renal dysfunction (creatinine clearance less than 60 mL/min)...

The CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, previous stroke, vascular disease, age 65-74 years, female gender) score is used to estimate thromboembolic risk in atrial fibrillation (AF). Its usefulness in predicting in-stent restenosis (ISR) is unknown. We evaluated the predictive value of the CHA2DS2-VASc score in AF-free patients who have undergone stent implantation. A total of 1350 patients who underwent coronary angiography and successful bare-metal stent implantation were analyzed...

OBJECTIVES: Atrioventricular nodal ablation (AVNA) is recommended for patients (pts) with cardiac resynchronization therapy (CRT) having atrial fibrillation (AF) and incomplete ventricular capture (Class IIa, level B). AVNA reduces mortality and improves the New York Heart Association (NYHA) functional class during intermediate term follow-up. The objectives were to study the long-term outcome regarding quality of life (QoL) and survival of our CRT pts after AVNA. DESIGN: 37 CRT-pts undergoing AVNA due to inadequate biventricular pacing were included in the study...

BACKGROUND: Aberrant vagal stimulation may promote the generation and propagation of atrial fibrillation (AF). Researchers have suggested that botulinum toxin (BTX), a neurotoxin that decreases neural vagal stimulation, may decrease the incidence of postoperative AF. The exact electrophysiologic mechanism underlying the observations and histopathologic alterations associated with BTX are unclear. OBJECTIVE: To investigate the electrophysiologic, functional, and histopathologic effects of BTX on fibrillation induction in ovine atria...

BACKGROUND: Polybasic helical peptides, such as peptide p5, bind human amyloid extracts and synthetic amyloid fibrils. When radiolabeled, peptide p5 has been shown to specifically bind amyloid in vivo thereby allowing imaging of the disease. Structural requirements for heparin and amyloid binding have been studied using analogs of p5 that modify helicity and chirality. METHODS: Peptide-ligand interactions were studied using CD spectroscopy and solution-phase binding assays with radiolabeled p5 analogs...

BACKGROUND: Although advancements in the treatment of atrial fibrillation have improved patient prognosis for this persistent condition, interest in atrial fibrillation development is growing. Of note is the fact that additional attention is being focused on the accompanying effect of insomnia. The aim of the study was to investigate the effects of insomnia on the risk of atrial fibrillation development. METHODS: This was a nationwide population-based retrospective cohort study using data from the Taiwan National health Insurance Research Database...

BACKGROUND: Pulmonary vein isolation (PVI) using the 2nd-generation cryoballoon (CB2) for the treatment of atrial fibrillation (AF) has demonstrated encouraging acute and mid-term results. However, follow-up data on outcomes beyond 1 year are sparse. We investigated the 3-year outcome after PVI using the CB2.Methods and Results:100 patients with paroxysmal (PAF, 70/100 [70%] patients) or persistent AF (pAF, 30/100 [30%] patients) underwent CB2-based PVI in 2 experienced centers in Germany...

BACKGROUND: Recent studies have shed light on the continued prescription of inpatient medications upon hospital discharge despite the original intent of short-term inpatient therapy. Amiodarone, an antiarrhythmic associated with significant adverse effects with long-term use, is commonly used for new-onset atrial fibrillation in critical illness (NAFCI). While it is often preferred in this setting of hemodynamic instability, a prescription for long-term use should be carefully considered, preferably by a cardiologist...

Formal guidelines play an important role in disseminating the best available evidence knowledge and are expected to provide simple and practical recommendations for the most optimal management of patients with various conditions. Such guidelines have important implications for many disease states, which thereby could be more professionally managed in everyday clinical practice by clinicians with divergent educational backgrounds, and also more easily implemented in wards or outpatient clinics eliminating inequalities in health care management...

The adenosine A2B receptor (A2BAR) has been identified as an important therapeutic target in cardiovascular disease, however in vitro and in vivo targeting has been limited by the paucity of pharmacological tools, particularly potent agonists. Interestingly, 2-((6-amino-3,5-dicyano-4-(4-(cyclopropylmethoxy)phenyl)-2-pyridinyl)thio)acetamide (BAY60-6583), a potent and subtype-selective A2BAR agonist, has the same core structure as 2-amino-6-[[2-(4-chlorophenyl)-1,3-thiazol-4-yl]methylsulfanyl]-4-[4-(2-hydroxyethoxy)phenyl]pyridine-3,5-dicarbonitril (capadenoson)...

BACKGROUND: Wide variation in out-of-hospital cardiac arrest (OHCA) survival has been reported, with low survival in urban settings. We sought to describe the epidemiology of OHCA in Philadelphia, Pennsylvania, the fifth largest U.S. city, and identify potential areas for targeted interventions to improve survival. METHODS AND RESULTS: Retrospective chart review of adult, non-traumatic, OHCA occurring in Philadelphia between 2008 and 2012. We determined incidence and epidemiological factors including: demographics, initial cardiac rhythm, bystander cardiopulmonary resuscitation, automated external defibrillator use, return of spontaneous circulation and 30-day survival...

Atrial fibrillation is more frequent in older patients, who have a higher risk of cardioembolic stroke and thromboembolism. Oral anticoagulant therapy is the standard of treatment for stroke prevention; however, under-prescription is still very common in older patients. The reasons underlying this phenomenon have not been systematically investigated, and true contraindications only partially account for it. An intimate skepticism on the real benefit-risk balance of oral anticoagulant therapy in the oldest patients seems to derive from the fact that most studies supporting it were conducted decades ago and included younger patients, with overall better functional and clinical status...

INTRODUCTION: Rotors and complex fractionated atrial electrograms (CFAEs) have been suggested as possible therapeutic targets in ablation of atrial fibrillation (AF). The aim of this study was to assess the relationship between rotors and CFAEs in patients with AF. METHODS: We studied 18 patients with AF (mean age 69±8 years, 33% female) who underwent rotor ablation and pulmonary vein isolation. Endocardial mapping was performed with a basket catheter to identify the presence, number and location of rotors and CFAEs...

Primary cardiac and pericardial tumors are rare entities with an autopsy frequency of 0.001-0.03%. Metastases to the heart and pericardium are much more common than primary tumors. Malignant pericardial mesotheliomas account for up to 50% of primary pericardial tumors. We report the case of a 75-year-old woman with hypertension, dyslipidemia and atrial fibrillation who went to the emergency department due to nonspecific thoracic discomfort of over six hours duration associated with syncope. Physical examination revealed a low-amplitude arrhythmic pulse, no heart murmurs and no signs of pulmonary congestion...

An 87-year-old man with persistent atrial fibrillation experienced heartburn and dysphagia at 2 years 9 months after initiation of dabigatran. An esophagogastroduodenoscopy demonstrated multiple longitudinal white plaques with ulcers in the narrowed midesophagus compressed between the left atrium and the tortuous aorta. We speculate that the esophageal stenosis contributed to stasis of dabigatran within the esophagus, resulting in prolonged mucosal contact with the caustic contents of the drug. Progressive enlargement of the left atrium may have led to the late onset of the potentially serious complication...

Management of chronic lymphocytic leukemia has changed markedly over the last several years with the emergence of several novel oral agents targeting B-cell receptor and Bcl-2 signaling pathways. For patients requiring treatment, ibrutinib, idelalisib, and venetoclax offer unique clinical benefits with a different set of therapeutic considerations compared with traditional parenteral therapy. Despite the conveniences afforded by oral therapy, these agents also carry unique logistical obstacles. Drug interactions with agents that are metabolized via the cytochrome P450 3A4 pathway are possible with all three agents...

Immunoglobulin light chain amyloidosis is a rare plasma cell dyscrasia characterized by deposition of abnormal amyloid fibrils in multiple organs impairing their function. In the largest cohort studied up to now of 118 CD138-purified plasma cell samples from previously untreated immunoglobulin light chain amyloidosis patients, we assessed in parallel copy number alterations using high-density copy number arrays and interphase fluorescence in situ hybridization. We used fluorescence in situ hybridization probes for the IgH translocations t(11;14), t(4;14), and t(14;16) or any other IgH rearrangement as well as numerical aberrations of the chromosome loci 1q21, 8p21, 5p15/5q35, 11q22...
