Objective: To identify patient and provider factors associated with lower rates of follow-up for positive depression screens in outpatient settings.
Design: Retrospective cohort study with electronic health record analysis investigating factors associated with follow-up care for patients with moderate-to-severe depressive symptoms. Patient and provider variables were associated with rates of follow-up for positive depression screens.
Article Synopsis
- Wolverines in North America have seen a reduction in their distribution due to human activities during the 19th and 20th centuries, leading to their threatened status in the US and special concern status in Canada.
- A study collected 882 genetic samples to analyze landscape connectivity factors, focusing on terrain complexity, human disturbance, forest configuration, and climate across a vast region of southwestern Canada and northwestern US.
- Findings showed that human disturbance negatively affects wolverine genetic connectivity, while forest cover and snow persistence help maintain genetic diversity, which can inform future conservation management efforts.
Previous studies have reported a potential occurrence of sleep disorders in patients following a COVID-19 infection. However, these findings were based on surveys or retrospective studies with small sample sizes. This study examined if subjects with a previous COVID-19 infection in 2020 experienced sleep disorders in 2021.

- Ross River virus (RRV) and Barmah Forest virus (BFV) are related viruses found in Australia and Papua New Guinea, showing evidence of convergent evolution in their genetic development.
- Analysis of multiple genomes revealed that specific mutations in key proteins are important for their replication and interaction with host cells, indicating similarities in how both viruses adapt to their environments.
- Although some mutations appear to have benefited their evolution, the overall selection pressures suggest that RRV and BFV have undergone purifying selection, maintaining stable functions during their replication in different hosts like mosquitoes and vertebrates.
