Virtual Loupes: A Pilot Study on the Use of Video Passthrough Augmented Reality in Plastic Surgery.

Background: Plastic surgeons use loupes or operative microscope to aid in tissue dissection and anastomosis of structures. These devices have their own limitations in areas of visualization and weight. Current uses of augmented and virtual reality in surgery have been limited to operative planning and simulation.

Tuberculosis and HIV/AIDS coinfection in patients attending Directly Observed Treatment Short-course (DOTS) centers in Anambra State, Nigeria: A retrospective study.

Background And Aims: This study retrospectively assessed the prevalence of TB and human immunodeficiency virus (HIV)/AIDS coinfection among patients that attended the Directly Observed Treatment Short-course (DOTS) centers in Anambra State, Southeast, Nigeria, between 2013 and 2017.

Methods: The study adopted a descriptive and retrospective epidemiological survey design. A total of 1443 case files of patients aged 15-60 who were treated in DOTS centers selected from Anambra State's 21 Local Government Areas between 2013 and 2017 were investigated.

Knowledge and Practice of COVID-19 Preventive Strategies among Nurses.

Background: Knowledge of COVID-19 preventive measures, in addition to appropriate practices of such measures, remains a necessity for the prevention of contracting COVID-19 by nurses. This study assessed nurses' knowledge and practice of COVID-19 preventive strategies. It also determined the influence of sociodemographic variables on the knowledge of preventive measures for COVID-19 among nurses.

Could eggshell membrane be an adjuvant for recombinant Hepatitis B vaccine?: A preliminary investigation.

Background: Despite the invasiveness of the Hepatitis B infection, its vaccines are only formulated with FDA-approved alum-based adjuvants, which poorly elicit a lasting immune response, hence the need for a more effective adjuvant system. This study evaluated the immunogenicity and toxicity of eggshell membranes (ESM) when administered as an adjuvant for the recombinant HBV vaccine (rHBsAg) in albino mice. Differential white blood cell analysis, as well as the titer measurement of Immunoglobulin G, subclass G1 and G2a on indirect ELISA, was performed to measure the immune-modulatory potentials of ESM.
