Cardiac POCUS: Another Tool In The Armory
Introduction.This study assessed the educational impact of hybrid cardiac Point of Care Ultrasonography (POCUS) training in a community-based academic setting.
Methods.Internal Medicine and Medicine/Pediatrics residents across all post-graduate years (PGY) at a midwestern medical school undertook a structured hybrid (online and hands-on teaching) model of POCUS training. Anonymous surveys with Likert-type scale responses were administered before and after the curriculum. Questions were categorized into domains to assess the residents’ interest in learning POCUS, their understanding of fundamental cardiac ultrasound (US) concepts, and their confidence in its application. The authors used Fisher’s Exact and t-test, and estimated odds ratios to gauge the impact of the training to achieve net scores above 0 on each domain.
Results. A total of 27 and 26 residents completed the pre-and post-training surveys, respectively. Experience with previous cardiac US use showed a positive skew. The training resulted in a significant increase in both, the understanding of the principles, and the residents’ confidence in its application. These findings were most significant amongst PGY 2 and 3 residents. Post-training mean scores were similar across all domains for subgroups of PGY level and previous ultrasound experience.
Conclusions.Residents displayed greater understanding of the fundamental cardiac ultrasound concepts with improved confidence levels after implementing a structured hybrid teaching model for POCUS. Future studies with objective assessment tools are needed to gauge the clinical impact of POCUS and its adoption rate in clinical practice to guide a recommendation for its incorporation into the residency curriculum
Kidney Recovery in Patients with Acute Kidney Injury Treated in Outpatient Hemodialysis or Rehabilitation Facilities
Rationale & Objective: Since January 2017, patients with acute kidney injury requiring dialysis (AKI-D) can be discharged to outpatient dialysis centers for continued hemodialysis (HD) support. We aimed to examine the rate of kidney recovery, time to recovery, and hospitalization-related clinical parameters associated with kidney recovery in patients with AKI-D.
Study Design: Single-center prospective cohort study.
Setting & Participants: 111 adult patients who were admitted to the University of Kentucky Hospital, experienced AKI-D, and were discharged with need of outpatient HD.
Exposure: Hospitalization-related clinical parameters were evaluated.
Outcome: Kidney recovery as a composite of being alive and no longer requiring HD or other form of kidney replacement therapy.
Analytical Approach: Discrete-time survival analysis and logistic regression were used to determine adjusted probabilities of kidney recovery at prespecified time points and to evaluate clinical parameters associated with recovery.
Results: 45 (41%) patients recovered kidney function, 25 (55.5%) within the first 30 days following discharge, 16 (35.5%) within 30 to 60 days, and 4 (9%) within 60 to 90 days. Adjusted probabilities of recovery were 36.7%, 27.4%, and 6.3%, respectively. Of the remaining patients, 49 (44%) developed kidney failure requiring chronic kidney replacement therapy and 17 (15%) died or went to hospice. Patients who did not recover kidney function were older, had more comorbid conditions, had lower estimated glomerular filtration rates at baseline, and received more blood transfusions during hospitalization when compared with those who recovered kidney function.
Limitations: Selection bias given that patients included in the study were all eligible for AKI management with outpatient HD as part of Medicare/Medicaid services.
Conclusions: At least one-third of AKI-D survivors discharged from an acute care hospital dependent on HD recovered kidney function within the first 90 days of discharge, more commonly in the first 30 days postdischarge. Future studies should elucidate clinical parameters that can inform risk classification and interventions to promote kidney recovery in this vulnerable and growing population
Isolated Right Ventricular Air Embolism
Vascular air embolism (VAE) is an uncommon but potentially life-threatening event often associated with various procedures and diagnostic tests. Understanding this challenging incident will enable physicians to evaluate, diagnose and manage this incident successfully. We present a case of a 73-year-old male who developed air in the right ventricle after intravenous contrast-enhanced computed tomography (CT) imaging. We aim at highlighting this challenging clinical scenario and emphasizing ways to assess the risks and implement means to prevent and treat accordingly

Obesity, inflammatory and thrombotic markers, and major clinical outcomes in critically ill patients with COVID‐19 in the US
Objective
This study aimed to determine whether obesity is independently associated with major adverse clinical outcomes and inflammatory and thrombotic markers in critically ill patients with COVID‐19.
Methods
The primary outcome was in‐hospital mortality in adults with COVID‐19 admitted to intensive care units across the US. Secondary outcomes were acute respiratory distress syndrome (ARDS), acute kidney injury requiring renal replacement therapy (AKI‐RRT), thrombotic events, and seven blood markers of inflammation and thrombosis. Unadjusted and multivariable‐adjusted models were used.
Results
Among the 4,908 study patients, mean (SD) age was 60.9 (14.7) years, 3,095 (62.8%) were male, and 2,552 (52.0%) had obesity. In multivariable models, BMI was not associated with mortality. Higher BMI beginning at 25 kg/m2 was associated with a greater risk of ARDS and AKI‐RRT but not thrombosis. There was no clinically significant association between BMI and inflammatory or thrombotic markers.
Conclusions
In critically ill patients with COVID‐19, higher BMI was not associated with death or thrombotic events but was associated with a greater risk of ARDS and AKI‐RRT. The lack of an association between BMI and circulating biomarkers calls into question the paradigm that obesity contributes to poor outcomes in critically ill patients with COVID‐19 by upregulating systemic inflammatory and prothrombotic pathways
