Distinctive Nanogels as High-Efficiency Transdermal Carriers for Skin Wound Healing.

J Biomed Nanotechnol 2020 Mar;16(3):304-314

We propose that nanogels (HLGs) prepared by simply blending an epidermal growth factor (EGF)-loaded hyaluronan (HA)-based nanoformulation and poloxamers can be efficient transdermal drug carriers. In particular, due to the thermogelling behavior of poloxamer, when the HLGs, which are liquid at room temperature, are applied to the skin's surface, they form a gel at skin temperature. First, lipid-based nanoformulations (EGF-LNs) were fabricated by the lipid thin film method and then chemically conjugated with HA on the surface of the films to prepare EGF-loaded HA-based nanoformulations (EGF-HLNs).

Zwitterionic Porous Conjugated Polymers as a Versatile Platform for Antibiofouling Implantable Bioelectronics.

ACS Appl Polym Mater 2020 Feb 5;2(2):528-536. Epub 2020 Feb 5.

Weldon School of Biomedical Engineering, Birck Nanotechnology Center, Center for Implantable Devices, Purdue University, West Lafayette, Indiana 47906, United States.

Here, we describe the design, synthesis, and evaluation of two kinds of multifunctional zwitterionic linear poly(carboxybetaine thiophene) (PCBTh) and porous poly(carboxybetaine thiophene--9,9'-bifluoreneylidene) (PCBTh-BF) polymers, which can be facilely synthesized using Yamamoto and Suzuki polycondensation, respectively. The integrations of zwitterionic polymer-based biomaterials that consist of conjugated polymer backbones, multifunctional zwitterionic side chains, and distorted units are designed and studied to address a key challenge of conjugated polymers in biomedical applications: biofouling phenomena that eventually lead to the failure and reduced lifetime of bioelectronics in the body. The introduction of a twisting unit into the polymer backbone allows us to tune the porosity, morphology, optical properties, and efficiency of antibiofouling features of resulting polymers.

Implantable Drug Reservoir Devices for Inner Ear Delivery of Pharmacotherapeutics.

Otolaryngol Head Neck Surg 2020 Jun 2:194599820930229. Epub 2020 Jun 2.

Department of Head and Neck Surgery, David Geffen School of Medicine at UCLA, Los Angeles, California, USA.

Objective: Cisplatin is a platinum-based chemotherapeutic drug that secondarily induces toxicity in inner ear sensory epithelia, contributing to auditory and vestibular dysfunction. We describe the creation of a drug reservoir device (DRD) to combat this ototoxicity for the duration of chemotherapy. As ototoxic side effects of chemotherapy may limit an oncologist's ability to prescribe first-line agents such as cisplatin, mitigating such devastating effects through prolonged topical therapy would be tremendously valuable.

Tailored Anticoagulation for Thromboembolic Risk Reduction in Paroxysmal Atrial Fibrillation.

J Innov Card Rhythm Manag 2018 Apr 15;9(4):3116-3125. Epub 2018 Apr 15.

Harvard-Thorndike Electrophysiology Institute, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA, USA.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, affecting up to six million people in the United States and more than 35 million individuals worldwide. Thromboembolism, including stroke, represents the most common AF-related morbidity and mortality and data indicate that anticoagulation can mitigate this risk by 65%. Our understanding of thromboembolism in AF, however, remains incomplete, and the mechanisms by which AF increases thromboembolic risk are areas of ongoing investigation and debate. Read More

Risk Stratification of Sudden Cardiac Death After Acute Myocardial Infarction.

J Innov Card Rhythm Manag 2018 Feb 15;9(2):3035-3049. Epub 2018 Feb 15.

Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA, USA.

Despite advances in the diagnosis and treatment of acute coronary syndromes and an overall improvement in outcomes, mortality after myocardial infarction (MI) remains high. Sudden death, which is most frequently due to ventricular tachycardia or ventricular fibrillation, is the cause of death in 25% to 50% of patients with prior MI, and therefore represents an important public health problem. Use of the implantable cardioverter-defibrillator (ICD), which is the primary method of reducing the chance of arrhythmic sudden death after MI, is costly to the medical system and is associated with procedural and long-term risks.

An "UninTENSional" Subcutaneous Implantable Cardioverter-defibrillator Shock.

J Innov Card Rhythm Manag 2018 Nov 15;9(11):3395-3397. Epub 2018 Nov 15.

Department of Cardiology, Sunnybrook Health Sciences Centre, Toronto, ON, Canada.

Subcutaneous implantable cardioverter-defibrillators (ICDs) (S-ICDs) are advantageous because they eliminate the need for transvenous leads. However, just like in the case of traditional ICDs, inappropriate shocks are an unwanted complication that may result following their placement. In this case, we discuss the mechanism of an inappropriate shock in a patient with an S-ICD. Read More

Implantable Cardiac Monitors: Evolution Through Disruption.

J Innov Card Rhythm Manag 2017 Sep 15;8(9):2824-2834. Epub 2017 Sep 15.

Department of Cardiology, Mercy Hospital, Mason City, IA.

Syncope and stroke are commonly seen in clinical practice, and the diagnostic workup is often time-consuming and costly and may increase resource utilization in the health-care system. The use of implantable cardiac monitors (ICMs) in syncope evaluation has been well studied, but their use in cryptogenic stroke evaluation and anticoagulation management in patients with atrial fibrillation (AF) is still emerging. The standard workup of the syncope patient or those at risk for a possible cardioembolic stroke includes the utilization of external cardiac monitors; however, these devices cannot provide long-term arrhythmia assessment, whereas ICMs can now last up to three years, increasing the possibility of arriving at a diagnosis.

Brugada Syndrome: Evolving Insights and Emerging Treatment Strategies.

J Innov Card Rhythm Manag 2017 Feb 15;8(2):2613-2622. Epub 2017 Feb 15.

Section of Cardiac Electrophysiology, Division of Cardiology, Department of Medicine, Western University, London, Ontario, Canada.

Brugada syndrome (BrS) is a rare inherited arrhythmia disorder associated with sudden cardiac death secondary to malignant ventricular arrhythmias. Since its first mention approximately 25 years ago, major strides have been made towards unraveling the condition's genetic and mechanistic underpinnings. Despite considerable progress, however, gaps in the understanding of BrS continue to persist, and clinical management of affected individuals remains challenging. Read More

Department of Medicine, Division of Cardiology, Electrophysiology Section, Columbia University, New York, NY, USA.

Silent atrial fibrillation (AF) is common. In some patients, it is the only manifestation of AF, while in others, the AF may be symptomatic or both symptomatic and asymptomatic. Regardless, however, to date, the significance, detection, and management considerations for silent AF have been incompletely elucidated. Read More

Electrical Storm in Patients with Implantable Cardioverter-defibrillators: A Practical Overview.

J Innov Card Rhythm Manag 2017 Oct 15;8(10):2853-2861. Epub 2017 Oct 15.

Electrophysiology Section, Cardiovascular Division, Hospital of the University of Pennsylvania, Philadelphia, PA.

Electrical storm (ES) is an increasingly common medical emergency characterized by clustered episodes of sustained ventricular arrhythmias (VAs) that lead to repeated appropriate implantable cardioverter-defibrillator (ICD) therapies. A diagnosis of ES can be made with the occurrence of three or more sustained episodes of VAs, or of three or more appropriate ICD therapies within 24 hours in patients with implanted devices. ES is associated with poor outcomes in patients with structural heart disease, particularly those with severe left ventricular dysfunction. Read More

A 62-year-old gentleman with a history of an ischemic cardiomyopathy and previous implantation of a biventricular cardioverter-defibrillator presented with complaints of palpitations and a wide complex ventricular paced rhythm at 120 bpm. This was originally thought to be ventricular tracking of an atrial tachycardia at the upper tracking rate, as the patient remained hemodynamically stable for three consecutive days in this rhythm. On the third day, the patient's implantable cardioverter-defibrillator (ICD) was interrogated and it was found that he was indeed in a sustained ventricular tachycardia with biventricular pacing being delivered as a function of the ventricular sense response feature.

The management of atrial fibrillation (AF) is among the most challenging aspects of cardiology and uncertainties abound concerning stroke assessment and stroke risk reduction. Currently, AF is viewed as a dichotomous variable (fully present or absent) when it comes to stroke risk; there is no regard to the amount of AF either spontaneously or due to rhythm control strategies. For this reason, monitoring in patients with a known AF history, particularly after ablation, has focused on easily measured outcomes such as time to recurrence. Read More

Optimal Strategies to Reduce Inappropriate Implantable Cardioverter-defibrillator Shocks.

J Innov Card Rhythm Manag 2019 Apr 15;10(4):3623-3632. Epub 2019 Apr 15.

University of Colorado, Aurora, CO, USA.

Since the widespread implementation of implantable cardioverter-defibrillators (ICDs), their effectiveness in various situations has become well-established. However, despite many advances in both the technology and its utilization, inappropriate therapy remains a risk. Here, we review ICD shocks, their effect on outcomes, and current methods to reduce inappropriate therapy, finding overall that inappropriate ICD shocks are common and associated with adverse outcomes.

Complete Atrioventricular Block with Intact Retrograde Conduction in Cardiac Rhythm Management Devices: Implications of the Phenomenon.

J Innov Card Rhythm Manag 2019 Apr 15;10(4):3617-3619. Epub 2019 Apr 15.

Abbott Laboratories, Chicago, IL, USA.

Intact retrograde ventriculoatrial (VA) conduction in the presence of complete atrioventricular (AV) heart block has been well-documented in the past. We sought to describe the prevalence and clinical significance of intact VA conduction accompanied by complete antegrade AV block in patients with implanted cardiac rhythm management (CRM) devices. During routine follow-up of CRM devices in our device clinic, 42 patients were found to be in a state of complete heart block. Read More
