Article Synopsis
  • This study focused on how Body Mass Index (BMI) influences radiation exposure in patients with chest pain undergoing different imaging techniques, highlighting the importance of optimizing doses for patient safety.
  • A total of 9,046 patients were analyzed, and results showed PET/CT had the lowest radiation exposure, particularly for patients with higher BMI, while CCTA had significantly higher doses in heavier patients.
  • The findings emphasize that while radiation doses for these imaging methods are generally modest, understanding BMI's impact is crucial for improving imaging practices and reducing unnecessary radiation exposure.

Article Synopsis
  • - The COVID-19 pandemic significantly disrupted cardiovascular testing in Latin America (LATAM), with a study finding a 21% decrease in procedure volumes from pre-pandemic levels in April 2021, contrasting with zero change in the rest of the world.
  • - Central America and Mexico experienced the largest reductions in procedures (47%), while healthcare centers in LATAM reported more staff layoffs and salary cuts than those in other regions.
  • - The study highlighted the lasting effects of the pandemic on cardiovascular care and emphasized the need for mental health support for healthcare workers in LATAM, as nearly 50% reported excessive psychological stress.

Article Synopsis
  • The study aimed to evaluate the recovery of cardiac diagnostic procedure volumes in Oceania during the COVID-19 pandemic by comparing data from March 2019, April 2020, and April 2021 across various health facilities.
  • Results showed that 11,902 procedures were performed in April 2021, slightly below pre-pandemic levels, while the rest of the world had similar recovery rates, indicating a small decline in both regions.
  • Although there were no significant differences in overall recovery rates, anatomical coronary testing in Oceania demonstrated poorer recovery compared to the rest of the world, raising concerns about specific diagnostic procedures.

Article Synopsis
  • The COVID-19 pandemic significantly disrupted cardiovascular care, particularly affecting noninvasive testing for coronary artery disease (CAD), with unclear trends across different income levels.
  • A global survey by the International Atomic Energy Agency included data from 669 centers in 107 countries, revealing that traditional tests decreased by 14%, while advanced tests increased by 15% from 2019 to 2021.
  • The rise in advanced testing mainly occurred in high- and upper middle-income countries, highlighting a growing disparity in CAD diagnostic practices between wealthier and lower-income nations.

Article Synopsis
  • The study aimed to assess how diagnostic cardiovascular procedure volumes rebounded in the U.S. and abroad during the year after COVID-19 hit, relying on data from 669 facilities worldwide.
  • In the early pandemic (April 2020), procedure volumes dropped significantly but showed a better recovery in U.S. facilities by April 2021 compared to non-U.S. facilities, although high-income non-U.S. countries showed similar recovery rates as the U.S.
  • Regional variations within the U.S. were noted, with the Midwest having the highest recovery rate, but no specific factors were found to predict recovery levels from the initial drop in procedure volumes.

Article Synopsis
  • The COVID-19 pandemic led to a significant decline in cardiovascular diagnostic procedures in Asia, with procedure volumes dropping by 47% from March 2019 to March 2020, and even more in low-income countries where reductions reached 81%.
  • A worldwide survey by the International Atomic Energy Agency highlighted that recovery began in some regions like Eastern Asia, especially China, between March and April 2020.
  • Changes in practices included the implementation of physical distancing and restricting visitors; however, COVID testing was infrequently conducted, despite being more common in one-third of Eastern Asian facilities.

Article Synopsis
  • This study analyzed the impact of the COVID-19 pandemic on cardiovascular procedure volumes in the U.S. compared to non-U.S. institutions, finding significant declines across both areas.
  • In April 2020, U.S. facilities experienced a 68% reduction in procedures, similar to the 63% decline in non-U.S. locations, but U.S. invasive coronary angiography procedures dropped more steeply (69% vs. 53%).
  • The study also noted more U.S. facilities adopted telehealth and patient screening measures, with volume reductions varying by region—most significantly in the Northeast and Midwest.

Rationale, Aims, And Objectives: To both examine the impact of preprint publishing on health sciences research and survey popular preprint servers amidst the current coronavirus disease 2019 (COVID-19) pandemic.

Methods: The authors queried three biomedical databases (MEDLINE, Web of Science, and Google Scholar) and two preprint servers (MedRxiv and SSRN) to identify literature pertaining to preprints. Additionally, they evaluated 12 preprint servers featuring COVID-19 research through sample submission of six manuscripts.
