    Abstract Here, we report a case of hereditary hyperhomocysteinemia presenting as dilated cardiomyopathy which was successfully diagnosed using a combination of point-of-care ultrasonography (POCUS) and echocardiogram (ECHO). A 39-year-old Caucasian male with a family history of homocystinuria and early deaths in adult male members from cardiovascular disease presented with complaints of purplish discoloration and 4/10 pain in bilateral feet along with severe nausea/vomiting for the last two days. Physical examination was significant for tachycardia, low normal mean arterial pressures, dry mucous membranes, right basilar crepitations, S3 gallop with holosystolic murmur along with peripheral cyanosis, and pitting edema. Laboratory examination revealed leucocytosis, elevated d-dimers, high anion gap metabolic acidosis secondary to worsening renal function, elevated liver enzymes, hyperhomocysteinemia, elevated B-type natriuretic peptide, and troponins along with low protein C and S. Electrocardiogram demonstrated left axis deviation with abnormal QRS-T angle and intraventricular conduction delay with a QRS duration of 133 ms. Bedside POCUS and ECHO revealed marked left ventricular dilatation with an ejection fraction of 10% and mitral regurgitation. Computed tomography angiography of the chest and abdomen was positive for partial left subclavian vein thrombus with extensive collateral formation and right-sided pleural effusion. The patient was started on anticoagulants and promptly transferred to a tertiary care center for left ventricular assist device placement. Hyperhomocysteinemia can present with atypical heart failure symptoms, and early usage of bedside POCUS and interpretation of findings in the context of family history are imperative for a successful diagnosis.

    Abstract The SARS-CoV-2, a novel virus has shown an association with central nervous system (CNS) symptoms. Initial retrospective studies emerging from China and France, as well as case reports from different parts of the world revealed a spectrum of neurological symptoms ranging from a simple headache to more serious encephalitis and dysexecutive syndromes. Authors have tried to explain this neurotropism of the virus by comparing invasion mechanisms with prior epidemic coronavirus like severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). Concrete evidence on those viruses has been limited. This review attempts to discuss various pathophysiological mechanisms as it relates to neurological complications of SARS-CoV-2. We will also discuss the neurological manifestations seen in various retrospective studies, systemic reviews, and case reports.

    Abstract Objective: The objective of this study was to develop a US-representative prediction model identifying factors with a greater likelihood of patients leaving without being seen.
    Methods: We conducted a retrospective cohort analysis using a 2016 nationwide emergency department (ED) sample. Patient factors considered for analysis were the following: age, sex, acuity, chronic diseases, weekend visit, quarter of presentation, median household income quartile for patient's zip code, primary/secondary insurance, total charges for the visit, and urban/rural household. Hospital factors considered were urban/rural location, trauma center/teaching hospital, and annual ED volume. Multivariable logistic regression was used to find significant predictors and their interactions. A random forest algorithm was used to determine the order of importance of factors.
    Results: A total of 32,680,232 hospital-based ED visits with 466,047 incidences of leaving without being seen were included. The cohort comprised 55.5% females, with a median (IQR) age of 37 (21-58) years. Positively associating factors were male sex (odds ratio [OR], 1.22; 99% confidence interval [CI], 1.17-1.26), lower acuity (
    Conclusion: Our derivation model reiterated several modifiable and non-modifiable risk factors for leaving without being seen established previously while rejecting the importance of others.

    Abstract Introduction: Our goal was to systematically review contemporary literature comparing the relative effectiveness of two mechanical compression devices (LUCAS and AutoPulse) to manual compression for achieving return of spontaneous circulation (ROSC) in patients undergoing cardiopulmonary resuscitation (CPR) after an out-of-hospital cardiac arrest (OHCA).
    Methods: We searched medical databases systematically for randomized controlled trials (RCT) and observational studies published between January 1, 2000-October 1, 2020 that compared mechanical chest compression (using any device) with manual chest compression following OHCA. We only included studies in the English language that reported ROSC outcomes in adult patients in non-trauma settings to conduct random-effects metanalysis and trial sequence analysis (TSA). Multivariate meta-regression was performed using preselected covariates to account for heterogeneity. We assessed for risk of biases in randomization, allocation sequence concealment, blinding, incomplete outcome data, and selective outcome reporting.
    Results: A total of 15 studies (n = 18474), including six RCTs, two cluster RCTs, five retrospective case-control, and two phased prospective cohort studies, were pooled for analysis. The pooled estimates' summary effect did not indicate a significant difference (Mantel-Haenszel odds ratio = 1.16, 95% confidence interval, 0.97 to 1.39, P = 0.11, I2 = 0.83) between mechanical and manual compressions during CPR for ROSC. The TSA showed firm evidence supporting the lack of improvement in ROSC using mechanical compression devices. The Z-curves successfully crossed the TSA futility boundary for ROSC, indicating sufficient evidence to draw firm conclusions regarding these outcomes. Multivariate meta-regression demonstrated that 100% of the between-study variation could be explained by differences in average age, the proportion of females, cardiac arrests with shockable rhythms, witnessed cardiac arrest, bystander CPR, and the average time for emergency medical services (EMS) arrival in the study samples, with the latter three attaining statistical significance.
    Conclusion: Mechanical compression devices for resuscitation in cardiac arrests are not associated with improved rates of ROSC. Their use may be more beneficial in non-ideal situations such as lack of bystander CPR, unwitnessed arrest, and delayed EMS response times. Studies done to date have enough power to render further studies on this comparison futile.

    Abstract In this systematic review, we compared the incidences of psychological issues during the COVID-19 pandemic, such as anxiety, depression, occupational stress, PTSD and insomnia, in healthcare workers (HCW) and non-healthcare workers (NHCW). PubMed, Ovid, Google Scholar and PsycInfo were systematically searched for related published articles. In all electronic databases, the following search strategy was implemented, and these key words were used: "COVID 19″ OR "SARS-CoV-2″ AND "psychological" OR "stress" OR "depression" AND "healthcare$". We identified 6 studies, out of the final 15 selected, which reported numerical estimates for incidences of psychological effects. Meta-analysis was conducted, comparing both combined and individual effect sizes of all psychological manifestations. Qualitative evidence was reported from the remaining 9 cross- sectional studies. The summary effects of the combined quantitative meta-analysis conducted on 6 studies did indicate near significant differences between HCW and NHCW. Summary effects of individual manifestations indicated significantly higher incidence of insomnia among HCW, when compared to NHCW. Qualitative evidence from remaining cross-sectional studies provided additional information into the nature of the psychological issues. We conclude that even though reasons for psychological distress among HCW and NHCW may be different, both suffered in equal measures excepting for insomnia.
