Atherothrombotic Outcomes After Sodium-Glucose Cotransporter 2 Inhibitors Versus Dipeptidyl Peptidase-4 Inhibitors in Patients With Type 2 Diabetes: A Territory-Wide Retrospective Cohort Study.

Background: This study compared the risks of atherothrombotic major adverse cardiovascular events in patients with type 2 diabetes taking SGLT2 (sodium-glucose cotransporter 2) inhibitors to those taking DPP-4 (dipeptidyl peptidase-4) inhibitors.

Methods And Results: All adult patients (≥18 years of age) with type 2 diabetes and newly prescribed with SGLT2 inhibitors or DPP-4 inhibitors across all public hospitals in Hong Kong between January 2015 and December 2019 were included. Patients were propensity matched in a 1:1 ratio using a caliper distance of 0.

Histiocyte-rich ROS1-rearranged inflammatory myofibroblastic tumour of the trachea: A rare neoplasm presenting with asthma-like symptoms.

Inflammatory myofibroblastic tumour is a rare tumour. We present an atypical case of Inflammatory myofibroblastic tumour which was trachea in location, histocyte rich and ROS1 rearranged. The patient presented with upper airway obstruction, which was an asthma mimic.

Clinical Outcomes of Left Atrial Appendage Occlusion Versus Switch of Direct Oral Antcoagulant in Atrial Fibrillation: A Territory-Wide Retrospective Analysis.

Background Left atrial appendage occlusion (LAAO) has emerged as an alternative to oral anticoagulation therapy for stroke prevention in atrial fibrillation, but data comparing LAAO with direct oral anticoagulant (DOAC) are sparse. Methods and Results This cohort study compared LAAO (with or without prior anticoagulation) with a switch of one DOAC to another DOAC by 1:2 propensity score matching. The primary outcome was a composite of all-cause mortality, ischemic stroke, and major bleeding.

Evaluating High-Confidence Genes in Conotruncal Cardiac Defects by Gene Burden Analyses.

Background In nonsyndromic conotruncal cardiac defects, the use of next-generation sequencing for clinical diagnosis is increasingly adopted, but gene-disease associations in research are only partially translated to diagnostic panels, suggesting a need for evidence-based consensus. Methods and Results In an exome data set of 245 patients with conotruncal cardiac defects, we performed burden analysis on a high-confidence congenital heart disease gene list (n=132) with rare (<0.01%) and ultrarare (absent in the Genome Aggregation Database) protein-altering variants.

Recommendations for surgical management of recurrent nasopharyngeal carcinoma during COVID-19 pandemic.

Nasopharyngeal carcinoma is endemic in southern parts of China including Hong Kong. Primary treatment entails radiotherapy ± chemotherapy depending on disease stage at presentation. Surgery is offered as a means of salvage for persistent and recurrent disease.

Influenza B/Streptococcal co-infection complicated by organizing pneumonia.

Organizing pneumonia is a rare complication of influenza infection that has substantial morbidity. We report the first case of organizing pneumonia associated with influenza B and Streptococcus pneumoniae coinfection that had significant improvement with corticosteroid treatment. The clinical and radiological features of organizing pneumonia associated with this coinfection are similar to those after influenza A infection.
