Appendiceal diverticulitis masked as acute appendicitis Open
Diverticula of the appendix have been the subject of study since the early 1900s. Appendiceal diverticulitis has varying presentations that can be acute or chronic and has features that differentiate it from classical acute appendicitis. W…

Comparison of conventional and novel rotational FNA needles using conventional microscopy and image analysis to quantitatively assess yield Open
Background There is increasing interest in designing new fine‐needle aspiration (FNA) needles to maximize tissue acquisition. This study compares cytological preparations from a new rotating FNA needle (CytoCore) with conventional FNA (Con…

A retrospective multi-site examination of chronic kidney disease using longitudinal laboratory results and metadata to identify clinical and financial risk Open
Background A retrospective observational study was conducted at 3 health care organizations to identify clinical gaps in care for patients with stage 3 or 4 chronic kidney disease (CKD), and financial opportunity from U.S. risk adjustment …

Antiarrhythmic Mechanisms of Epidural Blockade After Myocardial Infarction Open
BACKGROUND: Thoracic epidural anesthesia (TEA) has been shown to reduce the burden of ventricular tachycardia in small case series of patients with refractory ventricular tachyarrhythmias and cardiomyopathy. However, its electrophysiologic…

A Retrospective Multi-site Examination of Chronic Kidney Disease Using Longitudinal Laboratory Results and Metadata to Identify Clinical and Financial Risk Open
(350 words) Background: A retrospective, non-experimental, non-interventional study was conducted at 3 health care organizations to identify clinical gaps in care for patients with stage 3 or 4 chronic kidney disease (CKD), and financial o…

Thoracic epidural blockade after myocardial infarction benefits from anti-arrhythmic pathways mediated in part by parasympathetic modulation Open
Background Thoracic epidural anesthesia (TEA) has been shown to reduce the burden of ventricular tachyarrhythmias (VT) in small case-series of patients with refractory VT and cardiomyopathy. However, its electrophysiological and autonomic …

Updated Salivary Gland Immunohistochemistry: A Review Open
Context.— Salivary gland neoplasms are rare lesions in the head and neck (H&N) pathology realm. There are more than 20 malignant and 15 benign salivary gland neoplasms in the 5th edition of the World Health Organization classification of H…

Müllerian Cysts of the Posterior Mediastinum: A Case Report and Review of the Literature Open
Cysts can be segregated according to their embryonic backgrounds. The cysts that were found in the mediastinum are usually divided into bronchogenic cysts, enteric cysts, esophageal cysts, and nonspecific cysts. We add to the relatively sm…

Myocardial infarction reduces cardiac nociceptive neurotransmission through the vagal ganglia Open
Myocardial infarction causes pathological changes in the autonomic nervous system, which exacerbate heart failure and predispose to fatal ventricular arrhythmias and sudden death. These changes are characterized by sympathetic activation a…
View article: Scalable and reversible axonal neuromodulation of the sympathetic chain for cardiac control
Scalable and reversible axonal neuromodulation of the sympathetic chain for cardiac control Open
Autonomic imbalance and excess sympathetic activity have been implicated in the pathogenesis of cardiovascular disease and are targets for existing medical therapy. Neuromodulation may allow for control of sympathetic projections to the he…
View article: A novel metric linking stellate ganglion neuronal population dynamics to cardiopulmonary physiology
A novel metric linking stellate ganglion neuronal population dynamics to cardiopulmonary physiology Open
Activity of stellate ganglion neurons is often linking indirectly to cardiac function. Using novel approaches coupled with extended period of recordings in large animals, we link neuronal population dynamics to mechanical events occurring …

Innervation and Neuronal Control of the Mammalian Sinoatrial Node a Comprehensive Atlas Open
Rationale: Cardiac function is under exquisite intrinsic cardiac neural control. Neuroablative techniques to modulate control of cardiac function are currently being studied in patients, albeit with variable and sometimes deleterious resul…

Mechanism of ventricular premature beats elicited by left stellate ganglion stimulation during acute ischaemia of the anterior left ventricle Open
Aims Enhanced sympathetic activity during acute ischaemia is arrhythmogenic, but the underlying mechanism is unknown. During ischaemia, a diastolic current flows from the ischaemic to the non-ischaemic myocardium. This ‘injury’ current can…

Cardiac sympathetic activation circumvents high-dose beta blocker therapy in part through release of neuropeptide Y Open
The sympathetic nervous system plays an important role in the occurrence of ventricular tachycardia (VT). Many patients, however, experience VT despite maximal doses of beta blocker therapy, possibly due to the effects of sympathetic cotra…

Cardiac TRPV1 afferent signaling promotes arrhythmogenic ventricular remodeling after myocardial infarction Open
Chronic sympathoexcitation is implicated in ventricular arrhythmogenesis (VAs) following myocardial infarction (MI), but the critical neural pathways involved are not well understood. Cardiac adrenergic function is partly regulated by symp…
