A claims-based retrospective cohort study shows that patients who used bisphosphonates between 01/01/2019 and 02/29/2020 had dramatically reduced odds of SARS-CoV-2 testing, COVID-19 diagnosis, and COVID-19-related hospitalizations during the initial surge of the COVID-19 pandemic in the US.

A large observational study has found that irregular sleep-wake patterns are associated with a higher risk of overall mortality, and also mortality from cancers and cardiovascular disease.

Irregular sleep-wake patterns are associated with higher mortality risk, including mortality due to cancer and cardiovascular disease.

During the COVID-19 pandemic, cancer-related screening and healthcare practices varied (by age, race/ethnicity, education, and comorbidities), and considering these differences in high-risk individuals' monitoring is important as undiagnosed cases or poor prognosis may increase due to delayed screening/treatment.

Sociodemographic (age, race/ethnicity) and clinical (Eastern Cooperative Oncology Group performance status, pre-existing comorbidities, and active and progressing cancer) risk factors were associated with worse COVID-19 outcomes in patients with breast cancer.

Guidelines are presented to help researchers comply with sex-inclusive research mandates while upholding high standards of rigor.

A certain type of primary cancer may cause another second primary cancer which would be of clinical importance to make a personalized screening plan for certain primary cancer patients.

The use of within-host pathogen genomic sequence data can be used to improve phylogenetic and transmission estimates.

Leveraging time-varying and tissue-dependent genetic instruments into Mendelian randomization studies may help develop insight over more conventional applications.
