COVID-19: Factors Predicting Depressive Symptoms in People Aging With Long-Term Physical Disabilities.

The mental health impact of the COVID-19 pandemic may be greater than that of the viral infection. This impact is likely greater for disadvantaged groups such as people with long-term physical disabilities (PwLTPD). This cross-sectional study used a multiple linear regression model to examine factors associated with depressive symptoms and to understand their relative importance during the onset of the COVID-19 pandemic. The model explained 58% of the variance in depressive symptoms. Anxiety was the most important predictor, accounting for 8% of variance. Higher levels of anxiety, loneliness, and financial stress; prior diagnosis of depression; and non-Black race predicted a higher level of depressive symptoms in PwLTPD during the onset of the COVID-19 pandemic. Occupational therapy practitioners should strategically acknowledge predictors of depression that cannot be modified and actively address those that can be modified through evidence-based interventions to improve depressive symptoms in PwLTPD.

Multi-institution assessment of the use and risk of cardiovascular computed tomography in pediatric patients with congenital heart disease.

BACKGROUND: Cardiac computed tomography (CT) is increasingly used in pediatric patients with congenital heart disease (CHD). Variability of practice and of comprehensive diagnostic risk across institutions is not known. METHODS: Four centers prospectively enrolled consecutive pediatric CHD patients <18 years of age undergoing cardiac CT from January 6, 2017 to 1/30/2020. Patient characteristics, cardiac CT data and comprehensive diagnostic risk were compared by age and institutions. Risk categories included sedation and anesthesia use, vascular access, contrast exposure, cardiovascular medication, adverse events (AEs), and estimated radiation dose. RESULTS: Cardiac CT was performed in 1045 pediatric patients at a median (interquartile range, IQR) age of 1.7 years (0.3, 11.0). The most common indications were arterial abnormalities, suspected coronary artery anomalies, functionally single ventricle heart disease, and tetralogy of Fallot/pulmonary atresia. Sedation was used in 8% and anesthesia in 11% of patients. Peripheral vascular access was utilized for 93%. Median contrast volume was 2 â€‹ml/kg. Beta blockers were administered in 11% of cases and nitroglycerin in 2% of cases. The median (IQR) total procedural dose length product (DLP) was 20 â€‹mGy∗cm (10, 50). Sedation, vascular access, contrast exposure, use of cardiovascular medications and radiation dose estimates varied significantly by institution and age (p â€‹< â€‹0.001). Seven minor adverse events (0.7%) and no major adverse events were reported. CONCLUSION: Cardiac CT for CHD is safe in pediatric patients when appropriate CT technology and expertise are available. Scans can be acquired at relatively low radiation exposure with few minor adverse events.

Long-Term (3 Years) Outcomes of Ranolazine Therapy for Refractory Angina Pectoris (from the Ranolazine Refractory Registry).

Ranolazine is approved for patients with chronic stable angina but has not been formally studied in patients with refractory angina pectoris (RAP). Patients with RAP have limited therapeutic options and significant limitations in their quality of life. The Ranolazine Refractory Angina Registry was designed to evaluate the safety, tolerability, and effectiveness of ranolazine in RAP patients in order to expand treatment options for this challenging patient population. Using an extensive prospective database, we enrolled 158 consecutive patients evaluated in a dedicated RAP clinic. Angina class, medications, major adverse cardiac events including death, myocardial infarction, and revascularization were obtained at 12, 24, and 36 months. At 3 years, 95 (60%) patients remained on ranolazine. A ≥2 class improvement in angina was seen in 48% (38 of 80 patients with known Canadian Cardiovascular Society class) of those who remained on ranolazine. Discontinuation due to side effects, ineffectiveness, cost, and progression of disease were the principle reasons for discontinuation, but primarily occurred within the first year. In conclusion, ranolazine is an effective antianginal therapy at 3-year follow-up in patients with RAP and may reduce cardiac readmission.

Outcomes Before and After the Recall of a Heart Failure Pacemaker.

Importance: Timely and complete disclosure of medical device defects is necessary to manage patient care safely and effectively. Objectives: To determine if the manufacturer's recommendations following the recall of a medical device were timely and complete, the follow-up information and data provided to patients and physicians were adequate for managing patient care, and the actions taken by the US Food and Drug Administration (FDA) regarding the recall were appropriate. Design, Setting, and Participants: This single-center retrospective case series included 90 of 448 patients who were implanted with a cardiac resynchronization therapy pacemaker at the Minneapolis Heart Institute from May 2003 through January 2011; this pacemaker was recalled in November 2015. In addition, returned product reports submitted by the manufacturer to the FDA via the Manufacturer and User Facility Device Experience (MAUDE) database from January 2008 through December 2018 were analyzed. Main Outcomes and Measures: Clinical outcomes were serious adverse clinical events that occurred before and after the November 2015 recall notifying physicians and patients that the device's battery could fail unexpectedly because of high internal impedance. Technical outcomes were signs and causes of failure. Results: Five of 90 patients observed during 2015 experienced syncope when their pacemakers stopped pacing owing to battery or wire connection defects prior to the recall. Of the 90 patients, 37 (41%) were men, and the median (interquartile range) age at implantation was 71.3 (66.1-78.2) years. Analysis of the MAUDE data revealed that battery failures prior to the recall were associated with serious adverse events that included 1 death, 1 cardiac arrest, 5 syncopal attacks, and 6 heart failure exacerbations; 3 additional prerecall syncopal events were caused by wire connection defects. The manufacturer and the FDA were aware of the battery and wire connection defects for 19 months before issuing the recall, yet the wire connection problem was not included in the advisory and physicians were not informed that interrogating the pacemaker could result in loss of pacing. The FDA classified the recall as class II rather than the more critical class I. Conclusions and Relevance: This case series study of patients implanted with a defective pacemaker found that the pacemaker recall was delayed and that subsequent communications did not include all critical information needed for safe and effective patient care. These findings should prompt reforms in how the medical device industry and the FDA manage future medical device recalls.

Revascularization in Patients With Spontaneous Coronary Artery Dissection and ST-Segment Elevation Myocardial Infarction.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is an increasingly recognized cause of myocardial infarction (MI) in younger women, often treated conservatively due to revascularization risks. Revascularization outcomes are largely unknown in SCAD presenting with ST-segment elevation myocardial infarction (STEMI). OBJECTIVES: The purpose of this study was to compare revascularization strategies and outcomes of STEMI-SCAD with STEMI atherosclerosis (STEMI-ATH). METHODS: Consecutive STEMI patients were retrospectively analyzed (2003 to 2017) at 2 regional STEMI programs (Minneapolis Heart Institute and Cedars-Sinai Smidt Heart Institute) with 3-year outcomes. RESULTS: Among 5,208 STEMI patients, SCAD was present in 53 (1%; 93% female). SCAD prevalence was 19% in female STEMI patients age ≤50 years. Compared with STEMI-ATH, STEMI-SCAD patients were younger (age 49 ± 10 years vs. 63 ± 13 years), were more often female (93% vs. 27%), and had more frequent cardiogenic shock (19% vs. 9%); all p ≤ 0.03. In STEMI-SCAD, the culprit artery was more commonly left main (13% vs. 1%) or left anterior descending (47% vs. 38%); both p = 0.003. Acute revascularization was lower in STEMI-SCAD (70% vs. 97%); p < 0.001. In STEMI-SCAD, acute revascularization included percutaneous coronary intervention (PCI), n = 33 (62%), or bypass grafting, n = 4 (8%); PCI success was 91%. Those with revascularization were more likely to have shock, left main culprit, proximal dissection, and initial TIMI (Thrombolysis In Myocardial Infarction) flow grade 0 to 1. The 3-year survival was 98% for STEMI-SCAD versus 84% for STEMI-ATH; p < 0.001. CONCLUSIONS: STEMI-SCAD represents an important STEMI subset, particularly among younger women, characterized by significantly greater frequency of left main or left anterior descending culprit and cardiogenic shock than STEMI-ATH. Primary PCI is successful in most STEMI-SCAD patients, with low 3-year mortality.

Evaluation of a brief aerobic exercise intervention for high anxiety sensitivity.

Anxiety sensitivity, or the belief that anxiety-related sensations can have negative consequences, has been shown to play an important role in the etiology and maintenance of panic disorder and other anxiety-related pathology. Aerobic exercise involves exposure to physiological cues similar to those experienced during anxiety reactions. The present study sought to investigate the efficacy of a brief aerobic exercise intervention for high anxiety sensitivity. Accordingly, 24 participants with high anxiety sensitivity scores (Anxiety Sensitivity Index-Revised scores >28) were randomly assigned to complete either six 20-minute sessions of aerobic exercise or a no-exercise control condition. The results indicated that individuals assigned to the aerobic exercise condition reported significantly less anxiety sensitivity subsequent to exercise, whereas anxiety sensitivity scores among non-exercisers did not significantly change. The clinical research and public health implications of these findings are discussed, and several potential directions for additional research are recommended.
