Neurological monitoring in ECMO patients: current state of practice, challenges and lessons.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) in critically ill patients serves as a management option for end-stage cardiorespiratory failure in medical and surgical conditions. Patients on ECMO are at a high risk of neurologic adverse events including intracranial hemorrhage (ICH), acute ischemic stroke (AIS), seizures, diffuse cerebral edema, and hypoxic brain injury. Standard approaches to neurological monitoring for patients receiving ECMO support can be challenging for multiple reasons, including the severity of critical illness, deep sedation, and/or paralysis. This narrative literature review provides an overview of the current landscape for neurological monitoring in this population. METHODS: A literature search using PubMed was used to aid the understanding of the landscape of published literature in the area of neurological monitoring in ECMO patients. RESULTS: Review articles, cohort studies, case series, and individual reports were identified. A total of 73 varied manuscripts were summarized and included in this review which presents the challenges and strategies for performing neurological monitoring in this population. CONCLUSION: Neurological monitoring in ECMO is an area of interest to many clinicians, however, the literature is limited, heterogenous, and lacks consensus on the best monitoring practices. The evidence for optimal neurological monitoring that could impact clinical decisions and functional outcomes is lacking. Additional studies are needed to identify effective measures of neurological monitoring while on ECMO.

Outcomes in patients with sarcoidosis and COVID-19.

BACKGROUND AND AIM: The effect of COVID-19 in patients with sarcoidosis has not been fully explored. The aim was to conduct a retrospective cohort study investigating outcomes in patients with sarcoidosis who were hospitalized with COVID-19. METHODS: We included patients who had diagnoses of sarcoidosis and COVID-19 between January 1, 2020, and February 28, 2021. Primary outcomes included development of critical COVID-19; need for supplemental oxygen, noninvasive ventilation, and invasive ventilation; and death. Association of comorbidities and immunosuppression therapy with outcomes were analyzed. Multiple logistic regression analysis was used to assess risk factors associated with critical COVID-19. RESULTS: Of 1198 patients with COVID-19, 169 had sarcoidosis (14.1%) and 1029 (85.9%) did not (control group). Of the 169 patients with sarcoidosis and COVID-19, 84 (49.7%) were hospitalized (study group: mean age 62.4 years; 61.9% women; and 56.0% Black). The study group required supplemental oxygen (81% vs 62%; p = 0.001) and noninvasive ventilation (33.3% vs 6.4%; p < 0.001) more often and had lower mortality (15.5% vs. 30.4%; p = 0.004) than the control group. In patients hospitalized with COVID-19, sarcoidosis was not associated with critical COVID-19 (odds ratio, 0.77; 95% CI, 0.46-1.29; p = 0.317), but having sarcoidosis while taking immunosuppression therapy was associated with decreased risk of critical COVID-19 (odds ratio, 0.45; 95% CI, 0.31-0.65; p < 0.001). CONCLUSIONS: Patients with sarcoidosis may not be at increased risk of critical illness or death from COVID-19, and immunosuppression therapy in these patients may reduce the risk of critical COVID-19.

Differences in Baseline Characteristics and Outcomes in Young Caucasians and African Americans with Acute Myocardial Infarction.

BACKGROUND: The incidence of acute myocardial infarction (AMI) in young patients is increasing. While race-related differences in clinical characteristics and outcomes for older AMI patients have been well-studied, such differences in young patients are unknown. METHODS: We performed a retrospective review of charts of Caucasian and African American (AA) patients <50 years of age, presenting with AMI between 2010 and 2017 in an urban, community hospital in Detroit, Michigan. RESULTS: A total of 271 patients were identified with 156 being AAs (57.5%). Mean age was 43 years which was similar in both groups. AAs with AMI were 2.2 times more likely to be women and to have a history of diabetes and 1.2 times more likely to have BMI >30 kg/m2. History of coronary artery disease (1.8-fold) and hypertension (1.5-fold) were also more common in AAs. Overall presenting features were similar, other than that AAs presented more often with non-ST-elevation MI and tended to present less often with cardiac arrest. No differences were observed in the angiographic findings or in-hospital outcomes in the two groups, with the exception of lower need of mechanical support in AAs. CONCLUSIONS: In conclusion, our data provide important, not previously described information on race-related differences in history, presentation, clinical and angiographic features and outcomes in AAs compared with Caucasians younger than 50 with AMI. These findings may have implications for tailoring specific preventive strategies to decrease the incidence of AMI and its associated adverse events in both racial groups.

Myocardial Infarction Secondary to Blunt Chest Trauma.

Myocardial infarction (MI) following blunt chest trauma is rare, but potentially fatal. We treated a young patient for acute MI after falling chest-first on ice while playing hockey. Coronary artery bypass grafting (CABG) was performed after percutaneous stenting attempts were unsuccessful. By reviewing the related literature, we found 179 cases, the majority of which affected young males following road accidents. Left anterior descending artery was most frequently affected followed by right coronary artery particularly in their proximal thirds. Prior to the advent of emergent angioplasty for MI, conservative management was frequently pursued, whereas subsequently both stenting and CABG were performed as initial therapy. Several cases required CABG after the failure of stenting attempts. Trauma-associated MI is uncommon but should be suspected to be properly diagnosed and managed; the potential need for CABG requires that a cardiac surgeon be informed at the time of angiography to avoid possible delay in revascularization.
