Abstract Background Endoprosthestic or allograft reconstruction has become common following resection of malignant musculoskeletal tumors. Reported SSI rates after resection and reconstruction have been reported as high as 10 – 39% due to concurrent radiation and/or chemotherapy, compared to 0.6% - 2.0% in other orthopedic procedures. Though the optimal duration and perioperative antibiotic prophylaxis is well defined in other orthopedic procedures, there is little evidence to guide management in patients undergoing reconstruction with large endoprosthesis. At Moffitt Cancer Center (MCC), cefepime and vancomycin (FEP/VAN) were historically used for perioperative antibiotic prophylaxis; however, due to national logistical issues, these antibiotics were modified on June 6th, 2015 to cefazolin and vancomycin (CFZ/VAN). Methods We report a pre-post quasi-experimental interrupted time-series non-inferiority study conducted at MCC with 150 high-risk orthopedic surgery patients with a primary objective of demonstrating non-inferiority of CFZ/VAN to FEP/VAN with reducing early SSI rates for patients after tumor resection followed by reconstruction. Statistical analysis was performed utilizing a multivariate logistic regression analysis of the interventions and primary outcome. Data were processed and analyzed within the R version 4.0.2 software. Results Both groups included 75 patients with most common indications for surgery being sarcoma of any type (53%) and metastatic bone disease (27%), with the most common location of reconstruction at the distal femur (25%) and acetabulum (24%). Rates of early SSIs were low and numerically similar with 3 (4%) in the FEP/VAN group and 4 (5.4%) in the CFZ/VAN group. There was one instance of hardware removal due to infection within the FEP/VAN group. Baseline Characteristics Baseline characteristics for total study population, FEP/VAN, and CFZ/VAN Results including SSI rate, pathogens, infection Surgical site infection rates, culture site, group and interventions Conclusion Overall, the rates of early SSI rates at MCC between both groups are numerically lower compared to previous studies. Between groups, the rates are similar and supports the use of CFZ/VAN in this patient population. The low rate of early SSIs in this study may be attributed to several factors such as extended oral antibiotic prophylaxis at discharge. Further analysis is ongoing to determine the statistical significance of any differences between confounding variables. Disclosures All Authors: No reported disclosures

Effect Estimate

Introduction:According to guidelines, antibiotic prophylaxis in orthopedic surgery without implant is not recommended for the reduction of the incidence of surgical site infections (SSI); however, the evidence level is low. Surveys have shown that preoperative antibiotics for orthopedic procedures without implant are administered routinely by surgeons due to medico-legal concerns. Such practice may have an important impact on costs, side effects and the emergence of antibiotic resistance. Therefore, the objective of the review is to evaluate existing clinical evidence.Methods:A systematic review was performed with the use of Pubmed, EMBASE/MEDLINE, CENTRAL, SBBL-CILEA/METACRAWLER, ISRCTN Registry, ICTRP and ClinicalTrials.gov databases. Trials were initially screened by the title and abstract; secondly, full papers were analysed. The meta-analysis included randomized controlled trials (RCT) with patients undergoing surgery as treatment for any orthopedic impairment that did not need implantation. Heterogeneity analysis of the studies was conducted with chi-square. The statistical analysis of the infection rate was performed using the meta package with the R software. The effect estimate was expressed in risk ratio (RR) and pooled using a random effects model. Study quality assessment was undertaken using the Jadad scale.Results:Of the 184 identified papers, 129 were excluded since they did not meet inclusion criteria and 45 were discarded because they were considered to be duplicate publications. After analyzing the 10 potentially relevant studies, only two were included. The study population consisted of 1,152 patients. No heterogeneity was observed; however, the studies were outdated and associated with a high risk of bias. According to the pooled RR, the incidence of infection in the intervention group was lower than the control group favoring prophylaxis (RR = 0.39, 95% CI: 0.16−0.96, p = 0.040).Conclusions:The meta-analysis demonstrated, in contrast to the guidelines, that antibiotic prophylaxis can reduce the incidence of SSI in elective orthopedic surgeries without implant; however, the low number of available studies and the high risk of bias show that the effect estimate is not statistically significant. Considering that antibiotic prophylaxis is usually administered in clinical practice, RCTs are required to establish whether antibiotic prophylaxis in orthopedic procedures without implant is recommended or if this practice could cause more harm.

SummaryPurer factor IX (FIX) concentrates have been produced for the treatment of hemophilia B in the attempt to reduce the risk of thrombotic complications associated with the use of prothrombin complex concentrates. To evaluate ex vivo whether or not FIX concentrates activate the coagulation system in conditions associated with a high risk for thrombosis, we measured markers of hypercoagulability in 10 patients with hemophilia B who underwent surgery, mainly orthopedic procedures, covered by multiple concentrate infusions (40-80 U/kg/day). Postinfusion plasma levels of prothrombin fragment 1+2 and factor X activation peptide did not differ significantly from the presurgical levels, neither before nor after each concentrate dose. Therefore, it appears that prolonged treatment of patients with hemophilia B undergoing high risk surgical procedures with high doses of FIX concentrate does not cause systemic activation of coagulation. This suggests that purified FIX concentrates are preferable to prothrombin complex concentrates for conditions associated with an increased risk of thrombosis.

The Brain

BackgroundAlthough there are eight factors known to indicate a high risk of intracranial hemorrhage (ICH) in mild traumatic brain injury (TBI), identification of the strongest of these factors may optimize the utility of brain CT in clinical practice. This study aimed to evaluate the predictors of ICH based on baseline characteristics/mode of injury, indications for brain CT, and a combination of both to determine the strongest indicator.MethodsThis was a descriptive, retrospective, analytical study. The inclusion criteria were diagnosis of mild TBI, high risk of ICH, and having undergone a CT scan of the brain. The outcome of the study was any type of ICH. Stepwise logistic regression analysis was used to find the strongest predictors according to three models: (1) injury pattern and baseline characteristics, (2) indications for CT scan of the brain, and (3) a combination of models 1 and 2.ResultsThere were 100 patients determined to be at risk of ICH based on indications for CT of the brain in patients with acute head injury. Of these, 24 (24.00%) had ICH. Model 1 found that injury due to motor vehicle crash was a significant predictor of ICH, with an adjusted OR (95% CI) of 11.53 (3.05 to 43.58). Models 2 and 3 showed Glasgow Coma Scale (GCS) score of 13 to 14 after 2 hours of observation and open skull or base of skull fracture to be independent predictors, with adjusted OR (95% CI) of 11.77 (1.32 to 104.96) and 5.88 (1.08 to 31.99) according to model 2.DiscussionOpen skull or base of skull fracture and GCS score of 13 to 14 after 2 hours of observation were the two strongest predictors of ICH in mild TBI.Level of evidenceIII.

The Impact

Resections of primary pelvic bone tumors are frequently complicated by surgical site infections (SSIs), thereby impairing the functional prognosis of patients, especially in case of implant removal. Although prophylactic antibiotics play an essential role in preventing SSIs, there are presently no recommendations that support their appropriate use. This study aimed to assess the impact of a 24 h prophylactic protocol on the bacterial ecology, the resistance pattern, and the SSI healing rate. We hypothesized that this protocol not only limits the emergence of resistance but also results in a good cure rate with implant retention in case of SSI. A retrospective study was performed that included all patients with an SSI following a pelvic bone tumoral resection between 2005 and 2017 who received a 24 h antibiotic prophylaxis protocol. Twenty-nine patients with an SSI were included. We observed a 75.9% rate of polymicrobial infection, with a high prevalence of digestive flora microorganisms and a majority of wild-type phenotypes. We confirmed that there was no significant emergence of resistant flora. After first-line debridement, antibiotics (DA) if any implant was used, or debridement, antibiotics, and implant retention (DAIR) whenever possible, we obtained a 79.3% cure rate, with implant removal in 20% of cases. The absence of an implant was significantly associated with SSI healing. Early infection management and low resistance profiles may also have a positive effect, but this needs to be confirmed in a larger cohort. In light of this, the use of a 24 h prophylactic protocol in primary pelvic bone tumor resections is associated with a favorable infection cure rate and implant retention in case of SSI, and minimal selection of resistant microorganisms.
