Observational Study
Risk stratification of patients with atrial fibrillation in the emergency department.
Early and accurate risk stratification of patients with atrial fibrillation (AF) in the emergency department (ED) could aid the physician in determining a timely treatment strategy appropriate to the severity of disease. We conducted a retrospective review of 243 adult patients who presented to a tertiary ED with AF in 2017. Primary outcome studied was 30-day adverse event (a composite outcome of repeat visit to the ED, cardiovascular complications, and all-cause mortality). Secondary outcome studied was 90-day all-cause mortality. We compared the performance of the RED-AF, AFTER and CHA2DS2-VASc score by plotting receiver operating characteristic (ROC) curves and estimating the areas under curves (AUC), and assessed the potential to further improve the tools with their incorporation of new variables. ⋯ Existing scores collectively performed poorly to predict 30-day adverse outcomes, but the AFTER and Modified AFTER score showed good predictive value for 90-day mortality. Further studies should be done to validate their use in guiding clinician's disposition of patients with AF in the ED.

Myxedema Ascites is a rare finding of primary hypothyroidism, thereby leading to delayed diagnosis. However, prompt treatment with levothyroxine leads to complete resolution of the condition. We present a rare case of myxedema ascites in an elderly female and highlight the importance of early diagnosis and management. We also present ischemic colitis in the same patient, which has not been reported thus far in literature as a complication of myxedema ascites.

Comparative Study
Hemodynamic comparison of intravenous push diltiazem versus metoprolol for atrial fibrillation rate control.
Intravenous push (IVP) diltiazem and metoprolol are commonly used for management of atrial fibrillation (AF) with rapid ventricular rate (RVR) in the emergency department (ED). This study's objective was to determine if there was a significant difference in blood pressure reduction between agents. ⋯ IVP diltiazem and metoprolol caused similar SBP reduction and hypotension when used for initial management of AF with RVR in the ED. However, rate control was achieved more often with diltiazem.

Observational Study
Characteristics and prognosis of acute type A aortic dissection with negative D-dimer result.
Evidence regarding the characteristics and prognosis in acute type A aortic dissection (AAD) patients with negative D-dimer result is limited. We aimed to investigate the characteristics and prognosis in AAD patients with negative D-dimer result. ⋯ Negative D-dimer result is strongly influenced by white blood cell and symptom with pain. Negative D-dimer result was negatively associated with in-hospital mortality compared with positive group in AAD patients.
