Heterogeneous nanostructuring of MoSe2 over carbon nanotube (CNT) sponge as a free standing electrode not only bring higher performance but also, eliminates the need for dead elements such as a binder, conductive carbon and supportive current collectors. Further, the porous CNT sponge can be easily compacted via an in-tense densification of the active material MoSe2 to produce an electrode with a high mass loading for a signif-icantly improved areal capacity. In this work, we present a tunable coating of MoSe2 on a CNT sponge to fab-ricate a core-shell MoSe2@CNT anode...

We report on a compact, ultra-broadband, 2×2 adiabatic 3 dB coupler using silicon-on-insulator (SOI) strip waveguides assisted by sub-wavelength gratings (SWGs). In our device, two tapered SWG-assisted SOI strip waveguides achieve an adiabatic mode evolution of the two lowest-order transverse electric modes, in a two-waveguide system, for broadband 3 dB power splitting. Theory predicts that the proposed coupler will operate from 1200 nm to 1700 nm. We have been able to measure the performance of a device with a 15 μm long mode evolution region that achieves even, broadband power splitting over the 185 nm wavelength range of our tunable laser with an imbalance of less than ±0...

A 74-year-old female underwent an uneventful bilateral thoracoscopic maze procedure for persistent atrial fibrillation with continuous transesophageal echocardiographic (TEE) guidance. She presented six weeks later with persistent fever and focal neurological signs. Computed tomography of the thorax revealed air in the posterior LA, raising suspicion for an abscess versus an atrioesophageal fistula (AEF). Before undergoing an exploratory median sternotomy, an esophagogastroduodenoscopy (EGD) was performed by the surgeon to check for any esophageal pathology...

Chronic heart failure (HF) is one of the main causes of mortality and morbidity worldwide and represents a growing challenge in interventional cardiology. Its prevalence is recently increasing due to the improvements in cardiac care with subsequent significant reduction in the HF acute mortality. HF may occur with either a reduced left ventricular ejection fraction (LVEF) (LVEF<40%, HFrEF) or a preserved EF (typically LVEF≥50%, HFpEF) indicative of diastolic dysfunction. Despite recent advances in drug therapies as well as in nonpharmacological strategies, including defibrillators, cardiac resynchronization therapy, LV assist devices (LVAD), mortality in HF remains high...

The impact of sleep on LVAD patients' self-care behaviors is unknown. This study examined the patterns and changes of patients sleep quality (SQ), daytime sleepiness (DS), instrumental activities of daily living (IADL), and self-care capability (SCC) before and after LVAD. In addition, the relationships among these variables were explored. This observational study consisted of 38 subjects from two VAD Centers in Michigan. The subjects completed self-reported demographics and psychometrically sound SQ, DS, IADL, and SCC questionnaires before LVAD implant and at 1, 3, and 6 months after implant...

REVIEW
Judith E C Lieu
Purpose of Review: The aim of this study is to summarize the consequences of permanent unilateral hearing loss (UHL) on the development of children as documented in the recent literature. Recent Findings: Congenital and early-identified UHL places young children at risk for delays in speech-language development. School-aged children with UHL score lower on standardized tests of language and cognition and need increased assistance in school for educational and behavioral issues than siblings with normal hearing, and report lower hearing-related quality of life, similar to children with bilateral hearing loss (HL)...

STUDY: Implantation of a Left Ventricular Assist Device (LVAD) may produce both excessive local tissue stress and resulting strain-induced tissue rupture that are potential iatrogenic factors influencing the success of the surgical attachment of the LVAD into the myocardium. By using a computational simulation compared to mechanical tests, we sought to investigate the characteristics of stress-induced suture material on porcine myocardium. METHODS: Tensile strength experiments (n = 8) were performed on bulk left myocardium to establish a hyperelastic reduced polynomial constitutive law...

Incomplete spinal cord injury (iSCI) often leads to partial disruption of spinal pathways that are important for motor control of walking. Persons with iSCI present with deficits in walking ability due, in part, to inconsistent leg kinematics during stepping. While kinematic variability is important for normal walking, growing evidence indicates that excessive variability may limit walking ability and increase reliance on assistive devices (AD) after iSCI. The purpose of this study was to assess the effects of iSCI-induced impairments on kinematic variability during overground walking...

A series of peripherally dicyano-, tricyano- and tetracyano- substituted subphthalocyanines (SubPcs) have been prepared via microwave-assisted palladium-mediated cyanation of iodinated precursors. The introduction of π-acceptor cyano groups in the macrocycle clearly influences its electronic and redox properties, which are dependent on the number and relative position of these substituents. Additional functionalization of the SubPcs periphery with electron-donating or electron-withdrawing groups allows for a further fine tune of their features, leading to intensely-absorbing strong-electron-acceptor panchromatic dyes with low-lying LUMO energy levels...

INTRODUCTION: Ventricular arrhythmias are common in patients with advanced heart failure, which may also persist after sufficient intensive therapy for heart failure even with a left ventricular assist device. Although most ventricular arrhythmias have no hemodynamic relevance during left ventricular assist device support, some patients suffer from right ventricular decompensation due to ventricular arrhythmias resulting in severe hemodynamic deterioration and poor clinical outcomes. METHODS: We describe herein an left ventricular assist device patient with refractory ventricular arrhythmic storm early after left ventricular assist device implantation...

The ability of interventional cardiologists to identify high-risk percutaneous coronary interventions (PCI) patients, requires the integration of different features belonging to medical history, organ damage, coronary anatomy and the nature of the acute event. The selection of a subgroup of patients that could benefit from mechanical support during interventions is a key feature to success. The introduction of the Impella percutaneous axial pump have added an easy to set-up, less-invasive and time consuming active-support device to the interventional toolbox...
