Vaginal Packing After Pelvic Floor Reconstructive Surgery: Does the Soaking Agent Used for Packing (Bupivacaine, Estrogen or Saline) Impact Postoperative Pain Scores?

Study Objective: Vaginal packing is traditionally placed after pelvic floor reconstructive surgery (PFRS) to prevent hematoma formation. We seek to determine if there is a difference in postoperative pain scores after PFRS if vaginal packing is soaked with estrogen cream, bupivacaine, or saline. The primary outcome was pain as measured by a visual analog scale at 2 hours, 6 hours, and 1 day postoperatively.

Evaluation of Real and Perceived Risk to Health Care Workers Caring for Patients With the Omicron Variant of the SARS-CoV-2 Virus in Surgery and Obstetrics.

Objectives: The Omicron variant of the SARS-CoV-2 virus is described as more contagious than previous variants. We sought to assess risk to health care workers (HCWs) caring for patients with COVID-19 in surgical/obstetrical settings, and the perception of risk among this group.

Methods: From January to April 2022, reverse transcription polymerase chain reaction was used to detect the presence of SARS-CoV-2 viral ribonucleic acid in patient, environmental (floor, equipment, passive air) samples, and HCWs' masks (inside surface) during urgent surgery or obstetrical delivery for patients with SARS-CoV-2 infection.

Effect of Guanine Adduct Size, Shape, and Linker Type on the Conformation of Adducted DNA: A DFT and Molecular Dynamics Study.

DNA is damaged through various exogenous sources (e.g., automobile exhaust, tobacco smoke, and processed foods), which can yield diverse C8-dG bulky aryl adducts.

Mechanistic Insights into Bioengineered Antibiofilm Enamel Pellicles.

Dental caries remains the most widespread chronic disease worldwide. Basically, caries originates within biofilms accumulated on dental enamel. Despite the nonrenewable nature of the enamel tissue, targeted preventive strategies are still very limited.
