Our case illustrates a fatal course of infection with Gemella bergeriae endocarditis that was complicated by cardiogenic shock due to perforation of the mitral valve with severe mitral regurgitation, extension of infection into the myocardium adjacent to the mitral valve, and coronary sinus thrombosis.

Introduction: Tranexamic acid (TXA) decreases blood loss, perioperative transfusion rates, and cost in total hip and total knee arthroplasty. In a previous study, topical TXA decreased both perioperative blood loss and transfusions in patients undergoing resection of aggressive bone tumors and endoprosthetic reconstruction. The purpose of this study was to explore the cost effectiveness of TXA in patients undergoing resection of an aggressive bone tumor and endoprosthetic reconstruction, assessing transfusion cost, TXA administration cost, postoperative hospitalization cost, posthospital disposition, and 30-day readmissions. Methods: This study included 126 patients who underwent resection of an aggressive bone tumor and endoprosthetic resection at a single academic medical center; 61 patients in the TXA cohort and 65 patients in the non-TXA cohort. The cost of 1 unit of packed red blood cells, not including administration or complications, was estimated at our institution. The cost of hospitalization was estimated for lodging and basic care. The cost of TXA was $55 per patient. Patients were followed up for 30 days to identify hospital readmissions. Results: Patients in the TXA cohort experienced a TXA and blood transfusion cost reduction of $155.88 per patient (P = 0.007). Proximal femur replacement patients experienced a $282.05 transfusion cost reduction (P = 0.008), whereas distal femur replacement patients only experienced a transfusion cost reduction of $32.64 (P = 0.43). An average hospital admission cost reduction of $5,072.23 per patient (P < 0.001) was associated with TXA use. Proximal femur replacement patients who received TXA experienced a hospital cost reduction of $5,728.38 (P < 0.001), whereas distal femur replacement patients experienced a reduction of $3,724.90 (P = 0.01). No differences between the cohorts were identified in discharge to home (P = 0.37) or readmissions (P = 0.77). Discussion: TXA administration is cost effective in patients undergoing resection of an aggressive bone tumor and endoprosthetic reconstruction through reducing both perioperative transfusion rates and postoperative hospitalization. Level of evidence: III—Retrospective Cohort Study
Background and Objectives: Tranexamic acid (TXA) has been shown to decrease perioperative blood loss, transfusions, and cost in patients undergoing resection of aggressive bone tumors and endoprosthetic reconstruction. This study explored the effect of TXA administration on postoperative mobilization in these patients.Methods: This study included 126 patients who underwent resection of an aggressive bone tumor and endoprosthetic reconstruction; 61 patients in the TXA cohort and 65 patients in the non-TXA cohort. Postoperative physical therapy (PT) and occupational therapy notes were reviewed; patient ambulation distance and duration of therapies were recorded.Results: Patients in the TXA cohort ambulated further on all postoperative days, which was significant on postoperative Day 1 (POD1) (p = 0.002) and postoperative Day 2 (POD2) (p < 0.001). The TXA cohort ambulated 85% further per PT session 87.7 versus 47.4 ft (p < 0.001) and participated 14% longer, 36.1 versus 31.7 min (p < 0.001). Multivariate analysis identified a significant inverse association between postoperative hospitalization length and POD1, POD2, postoperative Day 3, and total ambulation (p < 0.001). Blood transfusion was independently associated with a 1.5 day increase in postoperative hospitalization (95% confidence interval: 0.64-2.5; p < 0.001).Conclusions: TXA administration was associated with increased postoperative ambulation and endurance. Increased postoperative ambulation was associated with decreased length of stay and increased likelihood to discharge home.
Background: Rotator cuff repair (RCR) is a well-studied procedure. However, the impact of patient sex on outcomes after RCR has not been well studied. Purpose: To conduct a systematic review and meta-analysis of sex-based differences in outcomes after RCR and to record what proportion of studies examined this as a primary or secondary purpose. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed using multiple databases according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Studies were included if they were written in English, performed on humans, consisted of patients who underwent RCR, evaluated at least 1 of the selected outcomes based on patient sex, and had statistical analysis available for their sex-based claim. Excluded were case reports, review studies, systematic reviews, cadaveric studies, and studies that did not report at least 1 sex-specific outcome or included certain other injuries associated with a rotator cuff injury. Results: Of 9998 studies screened and 1283 full-text studies reviewed, 11 (0.11%) studies with 2860 patients (1549 male and 1329 female) were included for quantitative analysis. None of these 11 studies examined the impact of patient sex on outcomes after RCR as a primary outcome. Postoperative Constant-Murley scores were analyzed for 7 studies. Male patients had a postoperative Constant-Murley score of 76.77 ± 15.94, while female patients had a postoperative Constant-Murley score of 69.88 ± 17.02. The random-effects model showed that male patients had significantly higher scores than female patients, with a mean difference of 7.33 (95% CI, 5.21-9.46; P < .0001). Analysis of retear rates in 5 studies indicated that there was no difference in the retear rate between sexes (odds ratio, 0.91 [95% CI, 0.49-1.67]). Conclusion: Female patients had lower postoperative Constant-Murley scores compared with male patients, but there was no difference in the retear rate. However, these results were based on an analysis of only 11 studies. The paucity of studies examining the impact of sex suggests that more research is needed on the impact of patient sex on outcomes after RCR.
