Sodium-glucose cotransporter-2 inhibitors improve cardiovascular outcomes post-acute coronary syndrome complicated by acute heart failure.

Background: Acute coronary syndrome (ACS) remains a risk factor for heart failure (HF). Therefore, we aimed to assess the cardioprotective role of sodium-glucose cotransporter-2 (SGLT2) inhibitors post-ACS in patients with acute HF (AHF) and diabetes.

Methods: We conducted a retrospective observational cohort study employing propensity score matching.

Syncope following Pfizer BioNTech (bnt162b2) vaccination unmasking Brugada syndrome.

The Brugada syndrome is an uncommon inherited condition associated with increased risk of ventricular tachyarrhythmias and sudden cardiac death. Different triggers including fever are well known to precipitate the Brugada pattern on electrocardiogram. We report a patient who presents with syncope, two days after the first dose of the BNT162b2 vaccine due to fever-related unmasking of Brugada syndrome.

Do the selection criteria of internal medicine residency program predict resident performance?

Background: Well-performing physician reflects the success of the residency program in selecting the best candidates for training. This study aimed to evaluate the selection criteria, mainly the United States Medical Licensing Examination (USMLE) Step 2 Clinical Knowledge (CK) results and applicants' status as international or locally trained applicants, used by the medical education department and the internal medicine residency program in Hamad Medical Corporation in Qatar to predict the residents' performance during their training.

Methods: A retrospective chart review was performed for three batches of graduates who started residency training in 2011, 2012, and 2013.

Acute myocarditis following administration of BNT162b2 vaccine.

The wide use of vaccines was linked with rare but serious complications in adults, causing a global concern. Here, we describe a young male patient, who presented with acute myocarditis, three days after the second dose of BNT162b2 vaccine.

Autoimmune Hemolytic Anemia in Chronic Myeloid Leukemia.

Background: Autoimmune hemolytic anemia (AIHA) might be associated with underlying hematological malignancies such as chronic lymphocytic leukemia. However, the association between AIHA and chronic myelogenous leukemia is extremely unusual.

Summary: We reviewed case reports and series of 54 patients with chronic myeloid leukemia (CML) who developed autoimmune hemolysis between 1952 and 2018.

Autoimmune Hemolytic Anemia After Relapse of Chronic Myeloid Leukemia: A Case Report.

Autoimmune hemolytic anemia is one of the differential diagnoses for anemia in patients with lymphoproliferative neoplasia, such as chronic lymphocytic leukemia, who experience sudden drop in hemoglobin. The association between autoimmune hemolytic anemia and chronic myeloid leukemia on the contrary is unusual. Here we present a patient with a background of chronic myeloid leukemia treated previously with Tyrosine Kinase Inhibitors, then developed autoimmune hemolysis simultaneously with chronic myeloid leukemia relapse.
