Psychological distress in pulmonary embolism survivors in a pulmonary embolism response team clinic: Protocol for a prospective observational study.

Background: Pulmonary embolism (PE) is a leading cause of cardiovascular death. Psychological distress in PE is understudied and underrecognized. Objectives: The primary aim of this proposed protocol was to describe the incidence of psychological distress symptoms (anxiety, depression, posttraumatic stress, and fear of recurrence) in the survivors of PE after discharge from hospitalization. The secondary aim was to assess the influence of acute disease, etiology, and treatment of PE on psychological distress. Methods: This is a prospective observational cohort study in a large tertiary care referral center. The participants are adult patients presenting to the hospital with PE fulfilling objective pulmonary embolism response team (PERT) activation criteria. After discharge, patients complete a series of validated measures of psychological distress (anxiety, depression, posttraumatic stress, and fear of recurrence) and quality of life at follow-ups approximately 1, 3, 6, and 12 months after diagnosis and treatment of their PE. Factors influencing each type of distress are evaluated. Conclusion: This protocol aims to identify the unmet needs of patients experiencing psychological distress following PE. It will describe anxiety, depression, fear of recurrence, and posttraumatic symptoms in PE survivors during the first year of outpatient follow-up in a PERT clinic.

Effects of Body Mass Index on Presentation and Outcomes of COVID-19 among Heart Transplant and Left Ventricular Assist Device Patients: A Multi-Institutional Study.

The coronavirus disease 2019 (COVID-19) pandemic continues to pose a significant threat to patients receiving advanced heart failure therapies. The current study was undertaken to better understand the relationship between obesity and outcomes of SARS-CoV-2 infection in patients with a left ventricular assist device (LVAD) or heart transplant. We performed a retrospective review of patients with a heart transplant or LVAD who presented to one of the participating 11 institutions between April 1 and November 30, 2020. Patients were grouped by body mass index (BMI) into obese (BMI ≥ 30 k/m2) and nonobese cohorts (BMI < 30 kg/m2). Multivariable logistic regression models were used to estimate effects of obesity on outcomes of interest. Across all centers, 162 heart transplant and 81 LVAD patients were identified; 54 (33%) and 38 (47%) were obese, respectively. Obese patients tended to have more symptoms at presentation. No differences in rates of hospitalization or ICU admission were noted. Obese patients with LVADs were more likely to require mechanical ventilation (39% vs. 8%, p < 0.05). No differences in renal failure or secondary infection were noted. Mortality was similar among heart transplant patients (11% [obese] vs. 16% [nonobese], p = 0.628) and LVAD patients (12% vs. 15%, p = 1.0). BMI was not associated with increased adjusted odds of mortality, ICU admission, or mechanical ventilation (all p > 0.10). In summary, acute presentations of SARS-CoV-2 among heart transplant and LVAD recipients carry a significantly higher mortality than the general population, although BMI does not appear to impact this. Further studies on the longer-term effects of COVID-19 on this population are warranted.

Comparative outcomes of cooled versus traditional radiofrequency ablation of the lateral branches for sacroiliac joint pain.

OBJECTIVES: Sacroiliac joint pain is a common cause of low back pain (LBP). Cooled radiofrequency ablation (c-RFA) of the lateral branches was recently introduced with the hypothesis that it creates larger lesions to overcome the anatomic variability of the lateral branches and achieve better outcomes as compared with the traditional radiofrequency approach (t-RFA). The objective of this comparative study is to determine if c-RFA is superior over t-RFA in providing longer pain relief. METHODS: Data on 88 patients were retrospectively collected between January 2006 and June 2009. Patients' pain relief was registered as <50%, 50% to 80%, or >80% at 1, 3, 6, and 12 months after procedure. The duration of pain relief, defined as the time until the patient reported <50% pain relief, served as our primary outcome. Demographic, morphometric, and procedural characteristics were analyzed using standard descriptive statistics and univariable tests. The relationship between RFA technique and duration of pain relief was evaluated using multivariable Cox regression. RESULTS: Among the 88 patients, 30 received t-RFA and 58 received c-RFA. We did not find a significant univariable relationship between RFA technique and duration of pain relief either before (P=0.76, Sun test) or after (P=0.95, Wald test) adjusting for the potentially confounding variables. Both cooled and traditional RFAs provided >50% pain reduction for 3 to 6 months in majority of the patients. DISCUSSION: This study did not reveal evidence that c-RFA of the lateral branches provides longer relief of sacroiliac joint pain as compared with t-RFA.
