- ItemContamination rate of the surgical gowns during total hip arthroplasty(2019) Klaber Rosenberg, Ianiv Walter; Ruiz, Pablo; Schweitzer Fernandez, Daniel Alberto; Lira Salas, María Jesús; Botello Correa, Eduardo Andrés; Wozniak Banchero, AnielaIntroduction: Surgical instrument contamination during total joint replacement is a matter of major concern. Available recommendations suggest changing suction tips, gloves and avoiding light handle manipulation during the procedure. There is a paucity of data regarding surgical gown contamination. The aim of the present study was to evaluate the contamination rate of surgical gowns (SGs) during total hip arthroplasty (THA) and secondarily compare it with other orthopedic procedures. Materials and methods: One hundred and forty surgical gowns (from 70 surgeries) were screened for bacterial contamination using thioglycolate (a high-sensitivity culture broth). The THA contamination rate was compared with those of knee and spine procedures. Controls were obtained at the beginning of every surgery and from the culture broth. The procedure’s duration and the level of training of the surgeon were evaluated as potential risk factors for contamination. Results: Bacterial contamination was identified on 12% of surgical gowns (22% of surgical procedures). The contamination rate during THA was 4.1% (2% in primary THA and 8.3% in revisions) vs 21.67% during other surgeries (spine and knee) (OR 6.15, p = 0.012). There were no contaminated SGs during THAs performed in ≤ 2 h (0/33 SGs) vs 7.5% (3/40) for THAs that took ≥ 2 h (p = 0.25). Conclusion: There was a high rate of SG contamination during orthopedic procedures that was higher during non-arthroplasty procedures and prolonged THAs. There were no contaminated surgical gowns in THAs under 120 min, efforts should point keeping primary THAs under this cutoff time. As a general recommendation, SGs should be changed every time there is concern about potential contamination. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

Alex; Sanchez, Brisa N.; Stankov, Ivana; Granados, Jose Tapia; SALURBAL GrpWe discuss the design, implementation, and results of a collaborative process designed to elucidate the complex systems that drive food behaviors, transport, and health in Latin American cities and to build capacity for systems thinking and community-based system dynamics (CBSD) methods among diverse research team members and stakeholders. During three CB SD workshops, 62 stakeholders from 10 Latin American countries identified 98 variables and a series of feedback loops that shape food behaviors, transportation and health, along with 52 policy levers. Our findings suggest that CBSD can engage local stakeholders, help them view problems through the lens of complex systems and use their insights to prioritize research efforts and identify novel solutions that consider mechanisms of complexity.
