The study was aimed at comparing intrapartum and postpartum outcomes between pregnant patients with and without antenatal COVID-19 infection using aggregated, deidentified electronic health record (EHR) data. This retrospective cohort study included data from over 80 health care organizations within the TriNetX Analytics Research Network. Individuals admitted for delivery from Jan 2020 to May 2023 were studied.

- The prevalence of unexpected positive intraoperative cultures (UPIC) in revision total knee arthroplasties (TKAs) is around 8.32%, with significant variability in reported findings across different studies due to differences in diagnostic methods for periprosthetic joint infection (PJI).
- A study analyzed 256 revision TKAs over 9 years, finding that 29.3% had at least one UPIC, and 13.28% were diagnosed as unsuspected PJI, leading to higher re-revision rates and treatment with antibiotics.
- After 24 months, a small percentage of patients (5.08%) required re-revision, with no reinfection cases linked to the same microorganisms, indicating that unsuspected PJ
Introduction: Clinical staging in lung cancer has implications for treatment planning and prognosis. We sought to determine the rate of inaccurate clinical stage (relative to pathologic), identify risk factors for inaccuracy, and evaluate the association of inaccuracy on survival. We hypothesized that inaccurate staging was associated with poor survival.

Methods: We identified patients admitted with a UTS condition from January to September 2017 in the National Readmissions Database.
Purpose: This work aimed to study clinical and neonatal outcomes of embryos derived from frozen compared to fresh donor oocytes in gestational carrier cycles.
Methods: This is a retrospective cohort study using the Society for Assisted Reproductive Technology Clinic Outcome Reporting System database between 2014 and 2015, comprising of 1284 fresh transfer cycles to gestational carrier recipients of embryos resulting from fresh (n = 1119) and vitrified/thawed (n = 165) donor oocytes. Models were adjusted for gestational carrier age, preimplantation genetic testing (PGT-A), number of embryos transferred, multiple gestation, and fetal heart reduction.
