Prophylactic Antibiotic Choice and Deep Infection in Lower Extremity Endoprosthetic Reconstruction: Comparison of Cefazolin, Cefazolin-Vancomycin, and Alternative Regimens.

INTRODUCTION: Infection is a common mode of failure in lower extremity endoprostheses. The Prophylactic Antibiotic Regimens in Tumor Surgery trial reported that 5 days of cefazolin had no difference in surgical site infection compared with 24 hours of cefazolin. Our purpose was to evaluate infection rates of patients receiving perioperative cefazolin monotherapy, cefazolin-vancomycin dual therapy, or alternative antibiotic regimens. METHODS: A single-center retrospective review was conducted on patients who received lower extremity endoprostheses from 2008 to 2021 with minimum 1-year follow-up. Three prophylactic antibiotic regimen groups were compared: cefazolin monotherapy, cefazolin-vancomycin dual therapy, and alternative regimens. The primary outcome was deep infection, defined by a sinus tract, positive culture, or clinical diagnosis. Secondary outcomes were revision surgery, microorganisms isolated, and superficial wound issues. RESULTS: The overall deep infection rate was 10% (30/294) at the median final follow-up of 3.0 years (IQR 1.7 to 5.4). The deep infection rates in the cefazolin, cefazolin-vancomycin, and alternative regimen groups were 8% (6/72), 10% (18/179), and 14% (6/43), respectively (P = 0.625). Patients not receiving cefazolin had an 18% deep infection rate (6/34) and 21% revision surgery rate (7/34) compared with a 9% deep infection rate (24/260) (P = 0.13) and 12% revision surgery rate (31/260) (P = 0.17) in patients receiving cefazolin. In those not receiving cefazolin, 88% (30/34) were due to a documented penicillin allergy, only two being anaphylaxis. All six patients in the alternative regimen group who developed deep infections did not receive cefazolin secondary to nonanaphylactic penicillin allergy. CONCLUSION: The addition of perioperative vancomycin to cefazolin in lower extremity endoprosthetic reconstructions was not associated with a lower deep infection rate. Patients who did not receive cefazolin trended toward higher rates of deep infection and revision surgery, although not statistically significant. The most common reason for not receiving cefazolin was a nonanaphylactic penicillin allergy, highlighting the continued practice of foregoing cefazolin unnecessarily.

Navigating the Enigma of Pediatric Musculoskeletal Infections: A Race Against Time.

Musculoskeletal infection (MSKI) in children is a critical condition in pediatric orthopedics due to the potential for serious adverse outcomes, including multiorgan dysfunction syndrome, which can lead to death. The diagnosis and treatment of MSKI continue to evolve with advancements in infectious organisms, diagnostic technologies, and pharmacologic treatments. It is imperative for pediatric orthopedic surgeons and medical teams to remain up to date with the latest MSKI practices.

Systematic Review Examining the Reporting of Race and Ethnicity in Sport-Related Concussion Studies.

OBJECTIVE: Sport-related concussion (SRC) is an evolving public health concern among youth athletes. Despite emerging evidence that race/ethnicity are important factors in determining concussion outcomes, studies examining race/ethnicity are limited. We conducted a systematic review to: 1) determine the prevalence of SRC studies that report race/ethnicity of their participants, 2) describe how race/ethnicity are used within each study, and 3) assess predictive factors for reporting of race/ethnicity. DATA SOURCES: PubMed/Embase/PsycINFO/CINAHL databases. STUDY SELECTION: Study inclusion criteria were: 1) primary/peer-reviewed research 2) related to the diagnosis/treatment/recovery of SRC 3) involving school-aged athletes (ages 5-25) 4) with ≥ 25 participants. The search was performed 03/2021 and included only studies published after 03/2013. DATA EXTRACTION: For each article, we looked at whether race/ethnicity were reported, and if so, which races/ethnicities were mentioned. For each race/ethnicity mentioned, we extracted the corresponding sample size and how they were used as variables in the study. DATA SYNTHESIS: Of 4,583 studies screened, 854 articles met inclusion criteria. Of the included articles, 132 (15.5%) reported race of their sample and 65 (7.6%) reported ethnicity, whereas 721 (84.4%) reported neither. When examining the demographic characteristics of the 132 studies that reported race, 69.8% of athletes were reported to be White. Additionally, 79.5% of these studies solely used race as a demographic descriptor as opposed to as a main exposure or covariate of interest. Studies published more recently were more likely to report race. Further, specific study/journal topics and geographic location of the authors were more likely to report race. CONCLUSIONS: Reporting of race/ethnicity is limited in current SRC literature. Future studies should improve the reporting of race/ethnicity, diversify study samples by focusing on enrolling athletes from underrepresented groups, and consider the potential impact of race/ethnicity as social determinants of health on risk factors, recovery, and long-term sequelae after SRC.

Overall health and health care utilization among Latino American men in the United States.

Although the Latino American male population is increasing, the subgroup Latino men's health remains underinvestigated. This study examined the overall pattern of Latino male health and health care utilization in major subgroups, using a nationally representative sample (N = 1,127) from the National Latino and Asian American Study. The authors evaluated rates of chronic, behavioral, and mental health service utilization in this first nationally representative survey. The results identified significant cross-subgroup differences in most physical and chronic conditions with Puerto Rican American men having high rates in 8 of 15 physical ailments, including life-altering conditions such as cardiovascular diseases. Despite differences in racial/ethnic, socioeconomic, and cultural factors, Cuban American men shared similar rates of heart diseases and cancer with Puerto Rican American men. In addition, Puerto Rican American men had higher rates of substance abuse than other Latinos. For health providers, the authors' findings encourage awareness of subgroup differences regarding overall health issues of Latino American men to provide culturally appropriate care.
