Abstract
BACKGROUND Severe heterotopic ossification (HO) (grades III and IV) after total hip arthroplasty (THA) over the last 25 years requiring excision is very uncommon. We performed a systematic review of the literature and reported a new case series with operative treatment after primary uncemented THA. METHODS A systematic review identified papers describing patients who had excision of HO after THA performed after 1988. Concepts of hip arthroplasty, HO, and surgical excision were searched in MEDLINE, Embase, and Scopus from database inception to November 2022. The inclusion criteria were articles that included specific patient data on the grade of HO, operative procedure, and prophylaxis. Studies were screened for inclusion by 2 independent reviewers. The extracted data included demographic data, the interval from index surgery to excision, clinical results, and complications. There was one surgeon who performed reoperation for ankylosis of primary THA in 3 men who had severe pain and hip deformity. RESULTS Data from 7 studies were included. There were 41 patients who had grade III or IV HO who had excision, and in 5 patients, revision of a component was also performed. Perioperative prophylaxis was irradiation alone in 10 patients, irradiation and indomethacin in 10 patients, and indomethacin alone in 21 patients. At a mean follow-up time of 14.8 months, the definition of the results was not uniform, and range of motion was improved, but relief of pain was inconsistent. There was one dislocation after resection without revision, one gastrointestinal complication, and 2 recurrences. Treatment of the 3 new patients, with wide excision of periarticular bone, selective exchange of components, and perioperative irradiation prophylaxis, was successful in improving pain, motion, and deformity. CONCLUSIONS There is insufficient good-quality data on the operative treatment of severe symptomatic HO after THA performed over the last 25 years. Prophylaxis with low-dose irradiation prevented a recurrence. Multicenter studies are needed to determine the optimum timing and prognosis for treatment.

Abstract
BACKGROUND Infection with vancomycin-resistant Enterococcus (VRE) in liver transplant recipients (LTR) has been associated with extended hospital stays, increased readmission rates, graft failure, and death. A tailored perioperative surgical prophylaxis regimen targeting VRE may reduce postoperative infections in VRE-colonized patients. This study investigated the outcomes of perioperative daptomycin in this patient population. METHODS This retrospective, single-center cohort study included LTR ≥ 18 years old who were VRE-colonized from June 2018 to November 2022. VRE colonization was identified by a VRE rectal swab screen or a positive VRE culture prior to transplant. Two groups were analyzed: daptomycin versus no daptomycin. All LTR received perioperative piperacillin-tazobactam for 24 h. If VRE-colonized, one dose of daptomycin (6 mg/kg) was given pre- and postoperatively. Demographics, clinical characteristics, risk factors for VRE infection, and daptomycin dose were collected. The primary outcome was VRE infection at 14 days and 90 days post-transplant. RESULTS There were 36 VRE-colonized LTR; 19 received daptomycin and 17 did not. Baseline characteristics and risk factors for VRE infection were similar between groups. More VRE infections occurred in the no daptomycin group within 14 days post-transplant (24% vs. 0%, p = .04), but at 90 days posttransplant there was no significant difference (29% vs. 16%, p = .43). The average daptomycin dose was 7.1 mg/kg. CONCLUSION Perioperative daptomycin reduced the rate of VRE infections in VRE-colonized LTR within 14 days posttransplant but not at 90 days. Future studies should evaluate if higher doses and/or longer duration of perioperative daptomycin can reduce VRE infections beyond 14 days post-transplant.

Abstract
Arthroplasty is a healthcare priority and represents high volume, high cost surgery. Periprosthetic joint infection (PJI) results in significant mortality, thus it is vital that the risk for PJI is minimized. Vancomycin is recommended for surgical prophylaxis in total joint arthroplasty (TJA) by current clinical practice guidelines endorsed by the Infectious Diseases Society of America. This study aimed to develop a new assay to determine vancomycin concentrations in serum and bone, and a minimal physiologically based population PK (mPBPK) model to evaluate vancomycin bone penetration in noninfected patients. Eleven patients undergoing TJA received 0.5-2.0 g intravenous vancomycin over 12-150 min before surgery. Excised bone specimens and four blood samples were collected per patient. Bone samples were pulverized under liquid nitrogen using a cryogenic mill. Vancomycin concentrations in serum and bone were analyzed by liquid chromatography-tandem mass spectrometry and subjected to mPBPK modeling. Vancomycin serum and bone concentrations ranged from 9.30 to 86.6 mg/L, and 1.94-37.0 mg/L, respectively. Average bone to serum concentration ratio was 0.41 (0.16-1.0) based on the collected samples. The population mean total body clearance was 2.12L/h/kg0.75. Inclusion of total body weight as a covariate substantially decreased interindividual variability in clearance. The bone/blood partition coefficient (Kpbone) was estimated at 0.635, reflecting the average bone/blood concentration ratio at steady-state. The model predicted median ratio of vancomycin area under the curve (AUC) for bone/AUC for serum was 44%. Observed vancomycin concentrations in bone were overall consistent with perfusion-limited distribution from blood to bone. An mPBPK model overall well described vancomycin concentrations in serum and bone.

Abstract
(1) Background: Postoperative infections are major contributors of morbidity and mortality after paediatric liver transplantation (pLTX). Evidence and recommendations regarding the most effective antimicrobial strategy are lacking. (2) Results: Of 39 pLTX centres, 20 responded. Aminopenicillins plus ß-lactamase inhibitors were used by six (30%) and third generation cephalosporins by three (15%), with the remaining centres reporting heterogenous regimens. Broad-spectrum regimens were the standard in 10 (50%) of centres and less frequent in the 16 (80%) centres with an infectious disease specialist. The duration ranged mainly between 24-48 h and 3-5 days in the absence and 3-5 days or 6-10 days in the presence of risk factors. Strategies regarding antifungal, antiviral, adjunctive antimicrobial, and surveillance strategies varied widely. (3) Methods: This international multicentre survey endorsed by the European Liver Transplant Registry queried all European pLTX centres from the registry on their current practice of perioperative antibiotic prophylaxis and antimicrobial strategies via an online questionnaire. (4) Conclusions: This survey found great heterogeneity regarding all aspects of postoperative antimicrobial treatment, surveillance, and prevention of infections in European pLTX centres. Evidence-based recommendations are urgently needed to optimise antimicrobial strategies and reduce the spectrum and duration of antimicrobial exposure.

Abstract
Surgical site infections (SSIs) represent a valid indicator of the healthcare quality. This study described the preliminary results of one-year active surveillance program on colon surgeries in a hospital in Molise region, central Italy. Patients who had undergone colon surgery according to National Healthcare Safety Network were included. Data on intervention, perioperative antibiotic prophylaxis, and SSIs occurrence were collected. Chi-square and Fisher's Exact test were used to evaluate any association between risk factors and SSIs. Sixty-eight patients (mean age 70.6 years) were included, and 44 (64.7%) were males. The most frequent interventions were right (n = 17, 25.0%) and left (n = 15, 22.0%) hemicolectomy. Surgical interventions were largely elective (n = 43, 63.2%) and with laparotomy (n = 56, 82.4%). During hospital stay, 10 (14.7%) SSIs were detected, including five superficial, three deep and two organ/space infections. Three (4.4%) additional SSIs were detected at post-discharge follow-up, for 13 (19.1%; CI95%: 9.7%-28.5%) total cases detected. Metronidazole plus Ceftriaxone (third generation cephalosporin) was the antibiotics combination mostly used (n = 36, 52.9%) for the perioperative antibiotic prophylaxis within 60 minutes of incision. The study underlines the need of improvements of the practices currently adopted, since SSIs could be significantly reduced through a multimodal strategy generating bundles. As third generation cephalosporins may facilitate resistant strains emergence, for perioperative prophylaxis in clean-contaminated interventions with entry into gastrointestinal tract, Cefazolin plus Metronidazole or only second generation cephalosporin are recommended. Due to the large variability of post-intervention antibiotic therapy, antimicrobial stewardship approach is strictly necessary.

Abstract
BACKGROUND Solid organ transplant (SOT) recipients can benefit from traditional antimicrobial stewardship (AMS) activities directed to improve judicious perioperative prescribing and management, but evidence is lacking. The aim of this expert opinion review is to provide an update on the current landscape of application of AMS practices for optimization of perioperative prophylaxis (PP). METHODS We reviewed the available literature on early postoperative infectious complications in SOT and PP management, on modified perioperative approaches in case of infection or colonization in recipients and donors and on AMS in transplantation PP. RESULTS SOT recipients are at high risk for early postoperative infectious complications due to the complexity of surgical procedures, severity of end stage organ disease, net state of immunosuppression in the posttransplant period and to the high risk for multidrug resistant organism. Moreover, SOT may be exposed to preservation fluid infections and expected or unexpected donor-derived infections. We summarize main factors to take into account when prescribing transplant PP. CONCLUSION Creating personalized PP to avoid unwanted consequences of antimicrobials while improving outcomes is an emerging and critical aspect in SOT setting. Further studies are needed to offer best PP tailored to SOT type and to evaluate interventions efficacy and safety.

Abstract
Objective Perioperative prophylaxis, commonly with a third-generation cephalosporin plus ampicillin or piperacillin-tazobactam, is usually employed to prevent infections in liver transplantation (LT) recipients. Patients with a high Model for End-Stage Liver Disease (MELD) score have an increased infection risk after LT. However, whether carbapenems could be used as surgical prophylaxis in these high-risk patients remains unclear. Therefore, this study aimed at comparing the effectiveness of carbapenems with that of cephalosporin or piperacillin-tazobactam for surgical prophylaxis in high-risk LT recipients with a MELD score ≥30. Design or Methods This retrospective study included adult patients with a MELD score ≥30 who underwent LT between May 2018 and September 2020. We comparatively analyzed the infection rate and outcome between patients using cefoperazone-sulbactam or piperacillin-tazobactam and those using carbapenems as surgical prophylaxis. Results This study included 105 LT recipients. Seventy-eight and 27 patients used non-carbapenem and carbapenem antibiotics, respectively, as surgical prophylaxis. The corresponding infection incidence rates within 30 days were 38.5% and 66.7% (p = 0.011). Multivariate analysis revealed that reoperation and the Child–Pugh score were independent risk factors for infections within 30 days after LT. The following four risk factors were associated with the 180-day post-LT survival: MELD score, vascular complication, intra-abdominal bleeding, and infection with carbapenem-resistant organisms (CROs). There was no significant difference in CRO infection incidence between the carbapenem and non-carbapenem groups (18.5% vs 11.5%; p = 0.345). Conclusion Carbapenem use as surgical prophylaxis was not associated with infection incidence within 30 days after LT, 180-day post-LT survival or CRO infection. Therefore, carbapenems are not superior to cephalosporin or piperacillin-tazobactam for perioperative antibiotic prophylaxis in LT recipients with a MELD score ≥30.

Abstract
Background—Appropriate perioperative antibiotic prophylaxis (PAP) is essential to prevent surgical site infections (SSIs) and to avoid antibiotics misuse. Aim—The aim of this study is to determine the effectiveness and long-term sustainability of an antimicrobial stewardship program (ASP), based on a clinical pathway (CP) and periodic education, to improve adherence to the guidelines for PAP in a tertiary care pediatric surgery center. Methods—We assessed the changes in PAP correctness and its effect on SSIs between the six months before and the 24 months after the implementation of ASP in the Pediatric Surgery Unit of the Department of Women’s and Children’s Health of Padova. The ASP was addressed to all surgeons and anesthesiologists of the Pediatric Surgery Unit. The primary outcome was appropriateness of PAP (agent, timing of the first dose, and duration). SSI rate was the secondary outcome. Results—1771 patients were included in the study and 676 received PAP. The overall correctness of the PAP, in terms of agent, timing, and duration, increased significantly after the CP implementation. What changed most was the PAP discontinuation within 24 h (p < 0.001). Cefazolin was the most used antibiotic, with a significant increase in the post-intervention period (p < 0.001) and with a reduction in the use of other broad-spectrum antibiotics. No variations in the incidence of SSIs were reported in the five periods (p = 0.958). Conclusion—The implementation of an ASP based on CP and education is an effective and sustainable antimicrobial stewardship tool for improving the correct use of PAP.

Abstract
BACKGROUND Vancomycin-resistant Enterococcus (VRE)-colonized liver transplantation (LT) recipients have increased post-LT morbidity, mortality, and higher rates of VRE infections compared with their non-colonized counterparts. Pre-LT screening for VRE colonization and inclusion of daptomycin in the perioperative antibiotic prophylaxis regimen may mitigate this risk. METHODS We performed a retrospective chart review of liver transplant recipients aged ≥ 18 years between 2013 and August 2019 to identify pre-LT VRE-colonized recipients and whether they received daptomycin perioperative prophylaxis (DPP). Demographic and clinical characteristics, including risk factors for VRE infection, were collected. Outcomes measured were VRE-related infection and all-cause mortality within 90 days of LT. RESULTS Of the 27 VRE-colonized liver transplant recipients within the study period, 25 received DPP. All recipients were admitted to the intensive care unit postoperatively, six (24%) required reoperation, fifteen (60%) required renal replacement therapy, and eight (32%) experienced postoperative hemorrhage within 90 days post-transplant. Two recipients (8%) experienced acute cellular rejection, but no primary graft failure was seen within 90 days. Among those who received DPP, no infections related to VRE or death was seen within 90 days of LT. The two VRE-colonized recipients who did not receive DPP both developed VRE bacteremia in the early post-LT period. CONCLUSION Despite having multiple risk factors for post-LT VRE infection, VRE-colonized recipients who received DPP did not develop VRE-related infections in the first 90 days post-LT. Our experience demonstrates that pre-LT VRE screening and DPP may be associated with a reduction in VRE infection in the early post-LT period, but this strategy warrants further evaluation in prospective studies.

Abstract
BACKGROUND Bone and joint infections remain a clinical challenge with potentially serious consequences. Nevertheless there is a lack of studies with strict criteria for diagnosis and etiology. The primary aim of this study was to determine the causative agents in orthopaedic infections using strict diagnostic criteria for infection and etiology. The secondary aim was to assess the timing of post-operative infections in relation to pathogens and to compare causative bacteria in different parts of the body. METHODS A retrospective registry study of 363 consecutive cases of bone and joint infections was performed. Microbiological data on sampling and culture results were registered. RESULTS Staphylococcus aureus dominated in both operated (45%) and non-operated (44%) patients, followed in frequency by coagulase-negative staphylococci (CoNS) in operated patients (11%) and beta-haemolytic streptococci in non-operated patients (16%) (p < 0.001). There were no polymicrobial infections in non-surgical cases (p < 0.001). For operated patients, Gram-negative bacilli were observed in 6%, almost exclusively isolated from the lower extremity. Propionibacterium spp. was the most common finding after spinal surgery. In 90/363 (25%), the agent responsible for the infection could not be defined according to the strict criteria used. CONCLUSION S. aureus dominated as etiological agent in all bone and joint infections, including operated patient given peri-operative prophylaxis. Improved timing of antibiotic prophylaxis seen after the introduction of the Swedish national project PRISS may have changed this. The number of infections with uncertain etiology was high, stressing the importance of more studies on diagnostics, as well as strict diagnostic algorithms.

Abstract
Background: Recent studies described an increase in acute kidney injury when high dose gentamicin was included in perioperative prophylaxis for orthopedic surgeries. To this effect, we compared the rate of nephrotoxicity for selected orthopedic surgeries where gentamicin was included (Gentamicin Group) to those where it was not included (Control Group) for perioperative prophylaxis and evaluated risk factors for nephrotoxicity. Methods: Spine, hip and knee surgeries performed between April 2011 and December 2013 were reviewed retrospectively. Gentamicin was given to eligible patients based on age, weight and Creatinine Clearance. Nephrotoxicity was assessed using Risk, Injury, Failure, Loss, End-stage kidney disease (RIFLE) criteria. Results: Among selected surgeries (N = 1590 in Gentamicin Group: hip = 926, spine = 600, knee = 64; N = 2587 in Control Group: hip = 980, spine = 902, knee = 705), patients’ body weight, serum creatinine, comorbidities and surgery duration were similar in Gentamicin Group and Control Group. Gentamicin median dose was 4.5 mg/kg of dosing weight. Nephrotoxicity rate was 2.5% in Gentamicin Group and 1.8% in Control Group, p = 0.17. Most cases of nephrotoxicity were Risk category by RIFLE criteria (67% in Gentamicin Group and 72% in Control Group, p = 0.49). In logistic regression, risk factors for nephrotoxicity were hospital stay >1 day prior to surgery (odds ratio = 8.1; 95% confidence interval = 2.25–28.97, p = 0.001), knee or hip surgery (odds ratio = 4.7; 95% confidence interval = 2.9–9.48, p = 0.0005) and diabetes (odds ratio = 1.95; 95% confidence interval = 1.13–3.35, p = 0.016). Receipt of gentamicin was not an independent predictor of nephrotoxicity (odds ratio = 1.5; 95% confidence interval = 0.97–2.35, p = 0.07). Conclusion: In this cohort, rate of nephrotoxicity was similar between Gentamicin Group and Control Group. Single high dose gentamicin is a safe and acceptable option for perioperative prophylaxis in eligible patients undergoing orthopedic surgeries.

Abstract
BACKGROUND Gastrointestinal (GI) complications of cardiovascular surgery, particularly bleeding, occur frequently. OBJECTIVE To determine factors that predict upper GI bleeding (UGIB) after cardiac surgery to improve prognostication and, thus, outcomes. METHODS The present case-control study reviewed institutional records spanning 2002 to 2005 for consecutive patients who developed in-hospital UGIB following cardiovascular surgery. Each case was matched to two to three controls for age, sex and date of hospital admission. Demographics, pharmacotherapy (including use of in-hospital acid suppression), endoscopic findings and outcomes were recorded. After adjustment for possible confounders, including Parsonnet score and demographic parameters, conditional logistic regression analysis identified independent significant predictors of the subsequent development of UGIB. RESULTS The study population consisted of 131 cases (mean [± SD] age 68.8±10.2 years, 69.5% male, mean Parsonnet score 24.6±14.2) and 387 matched controls (mean age 68.8±10.8 years, 70.0% male, mean Parsonnet score 20.9±14.2). UGIB events occurred a mean of 10.3±7.7 days after cardiac surgery. Duration of mechanical ventilation (OR 3.01 [95% CI 1.44 to 6.28]), elevation of international normalized ratio (OR 1.91 [95% CI 1.31 to 2.78]) and occurrence of Clostridium difficile colitis before bleeding (OR 3.15 [95% CI 1.19 to 8.36]) were independent risk factors. Use of histamine type 2 receptor antagonists (H2RAs) (OR 0.65 [95% CI 0.38 to 1.12]) or proton pump inhibitors (PPIs) (OR 0.60 [95% CI 0.27 to 1.32]) demonstrated trends toward protecting against UGIB after cardiac surgery. CONCLUSIONS GI bleeding events occurred approximately 10 days after cardiac surgery in patients with a complicated postoperative course. Significant predictors of subsequent bleeding included increased duration of mechanical ventilation and elevation of international normalized ratio; routine acid suppression with PPIs should be considered in such patients. C difficile colitis also significantly predicted UGIB, and H2RAs should be considered for acid suppression. Neither H2RAs nor PPIs were effective in preventing UGIB, although the small number of patients limits definitive conclusions regarding the role of acid suppression.
