Improving STEMI Management Internationally: Initial Report of the American College of Cardiology-Global Heart Attack Treatment Initiative.

Background: The burden of ST-segment elevation myocardial infarction (STEMI) worldwide is increasing as the leading cause of death; there are scant data on system-based initiatives and performance metrics relative to its management in low- and middle-income countries where resources are frequently limited.

Objectives: The Global Heart Attack Treatment Initiative (GHATI) ultimate aim is improving evidence-based STEMI care, adherence to guidelines, and tracking of clinical and institutional indicators in low- and middle-income countries. To achieve that goal, the process of care and outcomes of STEMI patients in those nations will be studied.

Cost-Effectiveness of Managing MIH Teeth.

Numerous therapeutic approaches are available for managing molar incisor hypomineralisation (MIH); however, the cost-effectiveness of these strategies is underexplored. Economic evaluations are crucial for determining the optimal treatment approach to individual patients' requirements. We systematically reviewed the literature on the topic to have a more comprehensive discussion about these issues.

Retrospective Analysis of Potential Lyme Disease Clinical Cases in Argentina.

Lyme disease, a multisystemic infectious disorder caused by pathogenic spirochetes of the genus transmitted by the bite of ticks, typically from the family Ixodidae, pose a significant public health issue worldwide. The (s.l.

Impact of Pressure Guidewire on Model-Based FFR Prediction.

Introduction: Fractional Flow Reserve (FFR) is used to characterize the functional significance of coronary artery stenoses. FFR is assessed under hyperemic conditions by invasive measurements of trans-stenotic pressure thanks to the insertion of a pressure guidewire across the coronary stenosis during catheterization. In order to overcome the potential risk related to the invasive procedure and to reduce the associated high costs, three-dimensional blood flow simulations that incorporate clinical imaging and patient-specific characteristics have been proposed.

Effectiveness of MRNA booster vaccine among healthcare workers in New York City during the Omicron surge, December 2021 to January 2022.

Objective: To describe effectiveness of mRNA vaccines by comparing 2-dose (2D) and 3-dose (3D) healthcare worker (HCW) recipients in the setting of Omicron variant dominance. Performance of 2D and 3D vaccine series against SARS-CoV-2 variants and the clinical outcomes of HCWs may inform return-to-work guidance.

Methods: In a retrospective study from December 15, 2020 to January 15, 2022, SARS-CoV-2 infections among HCWs at a large tertiary cancer centre in New York City were examined to estimate infection rates (aggregated positive tests / person-days) and 95% CIs over the Omicron period in 3D and 2D mRNA vaccinated HCWs and were compared using rate ratios.
