Outcomes of Oral Anticoagulation in Atrial Fibrillation Patients with or without Comorbid Vascular Disease: Insights from the GARFIELD-AF Registry.
Many patients with atrial fibrillation suffer from comorbid vascular disease. The comparative efficacy and safety of different types of oral anticoagulation (OAC) in this patient group have not been widely studied. ⋯ Atrial fibrillation patients with a history of vascular disease have worse long-term outcomes than those without. The association of NOACs vs VKA with clinical outcomes was more evident in atrial fibrillation patients with vascular disease.

The ongoing emergence of novel severe acute respiratory syndrome coronavirus 2 strains such as the Omicron variant amplifies the need for precision in predicting severe COVID-19 outcomes. This study presents a machine learning model, tailored to the evolving COVID-19 landscape, emphasizing novel risk factors and refining the definition of severe outcomes to predict the risk of a patient experiencing severe disease more accurately. ⋯ We offer an improved machine learning model and risk score for predicting severe outcomes during changing COVID-19 strain eras. By emphasizing a more clinically precise definition of severe outcomes, the study provides insights for resource allocation and intervention strategies, aiming to better patient outcomes and reduce health care strain. The necessity for regular model updates is highlighted to maintain relevance amidst the rapidly evolving COVID-19 epidemic.

Anemia (either pre-existing or hospital-acquired) is considered an independent predictor of mortality in acute coronary syndromes. However, it is still not clear whether anemia should be considered as a marker of worse health status or a therapeutic target. We sought to investigate the relationship between hospital-acquired anemia and clinical and laboratory findings and to assess the association with mortality and major cardiovascular events at long-term follow-up. ⋯ Hospital-acquired anemia affects one-third of patients hospitalized for acute coronary syndrome and is associated with age, frailty, and comorbidity burden, but was not found to be an independent predictor of long-term mortality.

Our objective was to explore evolving trends in US drug overdose mortality, overall and by age, sex, race, urbanization, and geography from 1999-2020. ⋯ Drug overdoses in the United States from 1999-2020 increased 4.3-fold, with the highest increase in White and Native American or Alaskan Native populations, and Midwest and non-metro areas. The data create preventive and therapeutic challenges, including restrictions on pharmaceutical industries and enhanced efforts by health care providers in safer prescribing. Addiction care should be integrated into all clinical practices, regardless of specialty, and into undergraduate, graduate, and continuing medical education. Targeted interventions are needed to adequately assess patients and provide care. Analytic studies designed a priori are necessary to test hypotheses formulated from these data.
