Characterizing the Use of Exercise Testing in Repaired Tetralogy of Fallot Patients: A Multi-Institutional Survey.

Cardiopulmonary exercise testing (CPET) is an important tool used in the management of patients with congenital heart disease. However, there are no clear guidelines for its use in specific populations, such as repaired Tetralogy of Fallot (rTOF). We sought to characterize current practice patterns and attitudes regarding exercise testing in the rTOF population using an online survey distributed to pediatric cardiologists.

Characterizing the Use of Exercise Testing in Repaired Tetralogy of Fallot Patients: A Multi-Institutional Survey.

Long-term survival for repaired Tetralogy of Fallot (rTOF) is excellent. We achieve this by close clinical monitoring to stratify prognosis and guide clinical decision-making. Cardiopulmonary exercise stress testing (CPET) is used to help guide clinical decision making; however, there are no clear guidelines for its use in this population.

Colorectal Cancer Screening Decisions From Student-Led Telemedicine Initiative During COVID-19.

Background And Objectives: With the onset of the COVID-19 pandemic, there has been a significant decrease in colorectal cancer (CRC) screening leading to delayed diagnoses and increased cancer deaths. To mitigate these burgeoning gaps in care, we developed a medical student-led service learning project aimed at improving rates of colorectal cancer screening at the Farrell Health Center (FHC), a primary care practice within the Ambulatory Care Network (ACN) at New York-Presbyterian Hospital.

Methods: A cohort of 973 FHC patients aged 50-75 years were identified as possibly overdue for screening.

Developmental Exposure to Low Concentrations of Organophosphate Flame Retardants Causes Life-Long Behavioral Alterations in Zebrafish.

As the older class of brominated flame retardants (BFRs) are phased out of commercial use because of findings of neurotoxicity with developmental exposure, a newer class of flame retardants have been introduced, the organophosphate flame retardants (OPFRs). Presently, little is known about the potential for developmental neurotoxicity or the behavioral consequences of OPFR exposure. Our aim was to characterize the life-long neurobehavioral effects of 4 widely used OPFRs using the zebrafish model.

Developmental exposure to low concentrations of two brominated flame retardants, BDE-47 and BDE-99, causes life-long behavioral alterations in zebrafish.

Background: Polybrominated diphenyl ethers (PBDEs) were widely used as flame retardants until the early 2000s, mainly in home furnishings and electronics. The persistence of PBDEs in the environment leads to continued ubiquitous exposure to low levels, with infants and children experiencing higher exposures than adults. Accumulating evidence suggest that low-level exposures during early life stages can affect brain development and lead to long-term behavioral impairments.
