https://academic.oup.com/ofid/article/9/10/ofac462/6762879
Open Forum Infectious Diseases; Adamson PC, .

Oct 19th, 2022 - Surges of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections among health care workers (HCWs) have led to critical staffing shortages. From January 4 to February 4, 2022, we implemented a return-to-work antigen testing program for HCWs, and 870 HCWs participated. Antigen test positivity was 60.5% for those ≤5 days from symptom onset or positive polymerase chain reaction (PC...

https://doi.org/10.1186/s12944-023-01778-3
Lipids in Health and Disease; Takanashi Y, Kahyo T et. al.

Jan 29th, 2023 - The risk of postoperative recurrence is higher in lung cancer patients who smoke than non-smokers. However, objective evaluation of the postoperative recurrence risk is difficult using conventional pathological prognostic factors because of their lack of reproducibility. Consequently, novel objective biomarkers that reflect postoperative risk in lung cancer patients who smoke must be identified...
