Continuing cancer care delivery during the peak of COVID-19 in the Bronx, New York: experience from a public teaching hospital.

INTRODUCTION: We report our experience with cancer care delivery during the peak of COVID-19 pandemic in New York City. METHODS: Retrospective analysis of the patients treated from the 1st of March, 2020 to the 8th of May, 2020. RESULTS: Team huddles, infection screening and patient selection strategies were implemented. One hundred and seventy patients were treated in 576 visits. Six developed severe COVID-19 requiring hospitalization, two died. Their median Charlson Comorbidity Index was 9, higher than the rest of the cohort. CONCLUSIONS: Cancer care delivery is safe and feasible using an approach focused on careful patient selection, team communication and infection control.

Survival With Continuous Outpatient Intravenous Inotrope Therapy in the Modern Era.

BACKGROUND: To describe baseline characteristics and outcomes in the largest known registry of advanced heart failure (HF) patients receiving continuous outpatient intravenous inotrope therapy. Studies evaluating the use of outpatient inotropes for palliation or as a bridge to advanced therapies were performed before current guideline directed medical and device therapy (GDMDT). There are limited data on the modern experience using outpatient inotrope (OI) therapy. STUDY QUESTION: We aimed to study current use and outcomes of OI. STUDY DESIGN: Retrospective database analysis. MEASURES AND OUTCOMES: From 2015 to 2017, 1540 advanced HF patients in a largess nationwide registry received OI with either milrinone or dobutamine. Baseline characteristics of 1149 patients data were retrospectively reviewed. Unadjusted Kaplan-Meier survival estimates censored at the time of transplant or mechanical circulatory support were reported. RESULTS: Of 1149 patients, more patients were treated with milrinone than dobutamine (64.6% vs. 35.4%). Regardless of the indication for OI, estimated 1 and 2-years survival was 61.8% and 41.6%, respectively. Milrinone use was associated with a greater 1-year survival than dobutamine (70.7% vs. 46.2%, P < 0.0001). The superiority of milrinone over dobutamine extended to all indications for OI, including bridge to transplant (85.9% vs. 71.3%, P < 0.0001), bridge to mechanical support (91.4% vs. 71%, P = 0.001), and palliation (73.6% vs. 63.3%, P < 0.001). After adjusting for indication, age, gender and weight, milrinone was associated with lower mortality than dobutamine (HR 0.50, 95% CI 0.39-0.64, P < 0.0001). CONCLUSIONS: In the largest dataset of HF patients receiving OI, survival on OI for palliation in the current era of GDMDT is significantly higher than previously reported. Compared with dobutamine, milrinone was associated with improved survival in all cohorts.

Vulnerable Plaque: A Review of Current Concepts in Pathophysiology and Imaging.

Advances in our understanding of the natural history and biology of atherosclerotic vascular disease led to the concept of a vulnerable plaque (VP), which is predisposed toward more rapid progression and acute coronary events. With newer technologies, we now have at our disposal high-quality imaging studies, both invasive and noninvasive, which promise in identifying plaque characteristics that make it more vulnerable. Upcoming trials aim to evaluate the utility of imaging VP in predicting clinical events. We discuss the role of VP imaging in managing atherosclerotic vascular disease.

Sacubitril/valsartan in cardiovascular disease: evidence to date and place in therapy.

Cardiovascular (CV) disease is a major cause of morbidity and mortality in the developing and the developed world. Mortality from CV disease had plateaued in the recent years raising concerning alarms about the sustained efficacy of available preventive and treatment options. Heart failure (HF) is among the major contributors to the CV-related health care burden, a persisting concern despite the use of clinically proven guideline-directed therapies. A requirement for more efficient medical therapies coupled with recent advances in bio-innovation led to the creation of sacubitril/valsartan, an angiotensin receptor-neprilysin inhibitor (ARNI), which demonstrated substantial CV benefit when compared with the standard of care, enalapril, in patients with HF and reduced ejection fraction. Further investigations of this novel combination ARNI at the tissue level shed light into the anti-remodeling and cardioprotective effects of sacubitril/valsartan, while clinical studies in the phenotypes of HF with preserved ejection fraction, hypertension and subsets, coronary outcomes, postmyocardial infarction, and renal disease suggested that this combination could be beneficial across a wide spectrum of CV disease. Sacubitril/valsartan is a much-needed therapeutic advance in the avenue of CV disease.

Managing Hypertension in Patients Aged 75 Years and Older.

On the basis of the available data, we would diagnose a normal blood pressure in elderly persons including those 75 years of age and older if the blood pressure was below 120/80 mmHg. We would diagnose hypertension in elderly persons including those aged 75 years and older if the systolic blood pressure was 130 mmHg and higher or if the diastolic blood pressure was 80 mmHg and higher. We would treat these elderly patients with hypertension to a blood pressure goal of less than 130/80 mmHg if the blood pressure was obtained by automated blood pressure monitoring in a quiet room. We would consider treating high-risk persons aged 75 years and older to a blood pressure goal of less than 120/80 mmHg if they were carefully monitored for serious adverse events. If the blood pressure is more than 20/10 mmHg above the goal blood pressure, we would initiate antihypertensive drug therapy with two antihypertensive drugs. The initial drug of choice for the treatment of hypertension in adults aged 75 years and older should be based on co-morbidities, co-incidental indications, tolerability, and cost.

Efficacy and safety of dronedarone in the treatment of patients with atrial fibrillation.

INTRODUCTION: Dronedarone, a derivative of amiodarone with structural modifications, was designed to have similar electrophysiological properties with a less toxic profile. Areas covered: Brief overview of the pharmacology of dronedarone followed by a summary of randomized clinical trials testing the efficacy of dronedarone in maintaining normal sinus rhythm and clinical outcomes associated with these trials. In depth discussion and commentary on trial findings which may seem contradictory at first approach and brief discussion of post-marketing surveillance studies. Expert opinion: Dronedarone is a moderately efficacious anti-arrhythmic agent which is safe for use in a carefully selected patient population, maintained in normal sinus rhythm, without advanced congestive heart failure, structural heart disease, permanent atrial fibrillation, digoxin use. It is especially useful in younger patients who lack other risk factors for cardiovascular events and, who stand to gain the most by avoiding long-term pulmonary and thyroid toxicities associated with more effective, but also significantly more toxic agents such as amiodarone.

Are two drugs better than one? A review of combination therapies for hypertension.

INTRODUCTION: Current guidelines for pharmacotherapy briefly describe a role for combination antihypertensive therapy. However, guidance on whether combination therapy should be used at the time of initiating therapy or as add on, and the choice of combination therapy is scarce. Areas covered: Current literature suggests that intensive blood pressure control is the key to managing cardiovascular risk. Along with lifestyle management, pharmacotherapy is an central component in the treatment of hypertension. Here, we aim to review the pathophysiology of hypertension, rationale for using combination therapy, and the different combinations of antihypertensive drug classes that are available in the market. Papers from 1967 through 2016 listed on PubMed on this topic were reviewed. Expert opinion: Based on the review of the literature, combination antihypertensive therapies are more effective than monotherapy and are also well tolerated, safe and cost effective for treatment of hypertension. Further research is needed to help guide the choice of combination antihypertensive therapy in different patient populations based on age, gender, race and comorbidities.
