Calvo CI, Hoy N, Rourke KF. Refining Bacteriuria as a Risk Factor for Complications After Urethroplasty: Identifying the Culprit. Urology 2024; 186:1-6. [PMID: 38354912 DOI: 10.1016/j.urology.2024.01.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Revised: 12/22/2023] [Accepted: 01/03/2024] [Indexed: 02/16/2024]
Abstract
OBJECTIVE To determine which bacteria are associated with an increased risk of 90-day complications after urethroplasty. Preoperative bacteriuria is associated with an increased risk of complications after urethroplasty. However, it remains unclear which specific micro-organisms are the primary drivers of this morbidity. METHODS A single-institution, 2-surgeon retrospective review was performed on patients undergoing urethroplasty from 08/2003 to 06/2021. Preoperative bacteriuria was considered significant when the patient had a mixed culture with ≥108 CFU/L or an identifiable micro-organism with ≥106 CFU/L. Descriptive statistics were used to summarize the results and chi-square was used to determine the association between 90-day complications (Clavien ≥2) and clinical characteristics/bacteria. RESULTS Out of 1611 patients, 23.2% (373) had significant preoperative bacteriuria. The most common pathogens included coagulase-negative staphylococcus 18.5% (69), mixed growth 15.8% (59), Escherichia coli 10.7% (40), and Enterococcus 14.2% (53). 7.9% (128/1611) experienced a significant 90-day complication (Clavien-Dindo ≥2). Gram-negative bacilli including E coli, Pseudomonas sp, Klebsiella sp, Serratia sp, Citrobacter sp, Achromobacter sp, Stenotrophomonas sp, and Morganella sp were associated with higher rates of postoperative complications (14.2%; P = .01) as well as Enterococcus sp (15.1%; P = .03). However, gram-positive cocci (7.9%; P = .97), gram-positive bacilli (11.8%; P = .47), mixed growth (5.1%; P = .54) and Candida (16.7%; P = .27) were not. Neither escalating concentrations of bacteria (P = .44) or number of strains (P = .08) were associated with increased risk of complications. CONCLUSION The main driver of bacteriuria-related complications after urethroplasty are gram-negative bacilli and Enterococcus sp. Patients with bacteriuria related to other micro-organisms can likely proceed with urethroplasty without increased risk of postoperative complications.

Propensity Score-Weighted Analysis of Postoperative Infection in Patients With and Without Preoperative Urine Culture. JAMA Netw Open 2024; 7:e240900. [PMID: 38436958 PMCID: PMC10912952 DOI: 10.1001/jamanetworkopen.2024.0900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 01/11/2024] [Indexed: 03/05/2024] Open
Abstract
Importance Although recent guidelines recommend against performance of preoperative urine culture before nongenitourinary surgery, many clinicians still order preoperative urine cultures and prescribe antibiotics for treatment of asymptomatic bacteriuria in an effort to reduce infection risk. Objective To assess the association between preoperative urine culture testing and postoperative urinary tract infection (UTI) or surgical site infection (SSI), independent of baseline patient characteristics or type of surgery. Design, Setting, and Participants This cohort study analyzed surgical procedures performed from January 1, 2017, to December 31, 2019, at any of 112 US Department of Veterans Affairs (VA) medical centers. The cohort comprised VA enrollees who underwent major elective noncardiac, nonurological operations. Machine learning and inverse probability of treatment weighting (IPTW) were used to balance the characteristics between those who did and did not undergo a urine culture. Data analyses were performed between January 2023 and January 2024. Exposures Performance of urine culture within 30 days prior to surgery. Main Outcomes and Measures The 2 main outcomes were UTI and SSI occurring within 30 days after surgery. Weighted logistic regression was used to estimate odds ratios (ORs) for postoperative infection based on treatment status. Results A total of 250 389 VA enrollees who underwent 288 858 surgical procedures were included, with 88.9% (256 753) of surgical procedures received by males and 48.9% (141 340) received by patients 65 years or older. Baseline characteristics were well balanced among treatment groups after applying IPTW weights. Preoperative urine culture was performed for 10.5% of surgical procedures (30 384 of 288 858). The IPTW analysis found that preoperative urine culture was not associated with SSI (adjusted OR [AOR], 0.99; 95% CI, 0.90-1.10) or postoperative UTI (AOR, 1.18; 95% CI, 0.98-1.40). In analyses limited to orthopedic surgery and neurosurgery as a proxy for prosthetic implants, the adjusted risks for UTI and SSI were also not associated with preoperative urine culture performance. Conclusions and Relevance This cohort study found no association between performance of a preoperative urine culture and lower risk of postoperative UTI or SSI. The results support the deimplementation of urine cultures and associated antibiotic treatment prior to surgery, even when using prosthetic implants.

Abstract
Introduction The contamination of dental unit waterlines (DUWLs) poses a significant risk of cross-infection in dentistry. Although chemical disinfectants have been effective in reducing number of bacteria, they do have limitations. Methods This study aimed to investigate the potential of chlorogenic acid, a natural substance with broadspectrum antibacterial properties, for treating DUWLs. Over a period of three months, we analyzed the microbial communities in 149 DUWLs samples collected from 5 dental units using high-throughput pyrophosphate sequencing. Results The results revealed that chlorogenic acid treatment had a significant impact on the microbial community profile in the DUWLs, with the most significant changes occurring within the first 15 days and stabilization observed in the last 30 days. The predominant genera detected in the samples were Bacteroides, Lactobacillus, Streptococcus, Methylobacterium, and Phreatobacter. Additionally, the relative abundance of certain beneficial bacteria, such as Alloprevotella, Roseburia, and Blautia, increased, while the presence of opportunistic pathogens like Mycobacteria significantly decreased. The functional prediction analysis using the KEGG database indicated a decrease in the pathogenicity of the bacterial community in the DUWLs following chlorogenic acid treatment. Discussion This study introduces a novel approach for the prevention and treatment of infections associated with dental care.

Utility of Routine Preoperative Urinalysis in the Prevention of Surgical Site Infections. World Neurosurg 2023; 180:e449-e459. [PMID: 37769846 DOI: 10.1016/j.wneu.2023.09.087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 09/17/2023] [Accepted: 09/20/2023] [Indexed: 10/03/2023]
Abstract
OBJECTIVE Preoperative assessment is important for neurosurgical risk stratification, but the level of evidence for individual screening tests is low. In preoperative urinalysis (UA), testing may significantly increase costs and lead to inappropriate antibiotic treatment. We prospectively evaluated whether eliminating preoperative UA was noninferior to routine preoperative UA as measured by 30-day readmission for surgical site infection in adult elective neurosurgical procedures. METHODS A single-institution prospective, pragmatic study of patients receiving elective neurosurgical procedures from 2018 to 2020 was conducted. Patients were allocated based on same-day versus preoperative admission status. Rates of preoperative UA and subsequent wound infection were measured along with detailed demographic, surgical, and laboratory data. RESULTS The study included 879 patients. The most common types of surgery were cranial (54.7%), spine (17.4%), and stereotactic/functional (19.5%). No preoperative UA was performed in 315 patients, while 564 underwent UA. Of tested patients, 103 (18.3%) met criteria for suspected urinary tract infection, and 69 (12.2%) received subsequent antibiotic treatment. There were 14 patients readmitted within 30 days (7 without UA [2.2%] vs. 7 with UA [1.2%]) for subsequent wound infection with a risk difference of 0.98% (95% confidence interval -0.89% to 2.85%). The upper limit of the confidence interval exceeded the preselected noninferiority margin of 1%. CONCLUSIONS In this prospective study of preoperative UA for elective neurosurgical procedures using a pragmatic, real-world design, risk of readmission due to surgical site infection was very low across the study cohort, suggesting a limited role of preoperative UA for elective neurosurgical procedures.

Abstract
Purpose Prosthetic joint infection (PJI) has an enormous physiological and psychological burden on patients. Surgeons rightly wish to minimise this risk. It has been shown that a standardised, evidence-based approach to perioperative care leads to better patient outcomes. A review of current practice was conducted using a cross-sectional survey among surgeons at multiple centers nationwide. Materials and Methods An 11-question electronic survey was circulated to hip and knee arthroplasty consultants nationally via the BOA (British Orthopaedic Association) e-newsletter. Results The respondents included 56 consultants working across 19 different trusts. Thirty-four (60.7%) screen patients for asymptomatic bacteriuria (ASB) preoperatively, with 19 (55.9%) would treating with antibiotics. Fifty-six (100%) screen for methicillin-resistant Staphylococcus aureus and treat if positive. Only 15 (26.8%) screen for methicillin-sensitive S. aureus (MSSA) or empirically eradicate. Zero (0%) routinely catheterise patients perioperatively. Forty-one (73.2%) would give intramuscular or intravenous gentamicin for a perioperative catheterisation. All surgeons use laminar flow theatres. Twenty-six (46.4%) use only an impervious gown, 6 (10.7%) exhaust pipes, and 24 (42.3%) surgical helmet system. Five different antimicrobial prophylaxis regimens are used 9 (16.1%) cefuroxime, 2 (3.6%) flucloxacillin, 19 (33.9%) flucloxacillin and gentamicin, 10 (17.9%) teicoplanin, 16 (28.6%) teicoplanin and gentamicin. Twenty-two (39.3%) routinely give further doses. Conclusion ASB screening, treatment and intramuscular gentamicin for perioperative catheterisation is routinely practiced despite no supporting evidence base. MSSA screening and treatment is underutilised. Multiple antibiotic regimens exist despite little variation in organisms in PJI. Practice varies between surgeons and centers, we should all be practicing evidence-based medicine.

J Arthroplasty 2023; 38:2142-2148. [PMID: 37172791 DOI: 10.1016/j.arth.2023.04.067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 04/27/2023] [Accepted: 04/30/2023] [Indexed: 05/15/2023] Open
Abstract
BACKGROUND Whether symptomatic benign prostatic hyperplasia (sBPH), which is common among middle-aged and older men, affects the risk of periprosthetic joint infection (PJI) remains controversial. The present study explored this question among men undergoing total knee arthroplasty and total hip arthroplasty (TKA and THA). METHODS We retrospectively analyzed medical data from 948 men who underwent primary TKA or THA at our institution between 2010 and 2021. We compared the incidence of postoperative complications such as PJI, urinary tract infection (UTI), and postoperative urinary retention (POUR) between 316 patients (193 hips and 123 knees) who did and 632 patients who did not have sBPH; the 2 groups of patients were matched to each other in a 1:2 ratio based on numerous clinical demographic variables. In the subgroup analyses, we stratified sBPH patients according to whether they began anti-sBPH medical therapy prior to arthroplasty. RESULTS PJI following primary TKA was significantly more common among sBPH patients than among patients who did not have sBPH (4.1 vs 0.4%; P = .029), as were UTI (P = .029), and POUR (P < .001). Patients who had sBPH also had an increased incidence of UTI (P = .006) and POUR (P < .001) following THA. Among sBPH patients, those who started anti-sBPH medical therapy before TKA suffered significantly lower incidence of PJI than those who did not. CONCLUSION Symptomatic benign prostatic hyperplasia is a risk factor for PJI after primary TKA among men, and starting appropriate medical therapy before surgery can reduce the risk of PJI following TKA and postoperative urinary complications following TKA and THA.

Abstract
The postoperative burden remains significant due to the possibility of prolonged hospitalization, escalated healthcare costs, and patient distress caused by postorthopedic surgical site infections (SSIs). Orthopedic surgery is likewise faced with a significant challenge posed by these conditions. A positive association has been observed between the presence of postorthopedic SSIs and heightened susceptibility to adverse health outcomes, along with elevated rates of morbidity and mortality. Systemic antibiotic prophylaxis (SAP) reduces the risk of acquiring an SSI. Closed fractures, open fractures, arthroplasty, and percutaneous fixation each possess distinct attributes that impact the data and antimicrobial therapy. When implementing SAP, it is crucial to strike a delicate equilibrium between maintaining effective antibiotic stewardship protocols and preventing the occurrence of SSIs. This practice effectively prevents both the incidence of negative consequences and the emergence of antibiotic resistance. The objective of this study was to examine the existing literature on the use of surgical antibiotic prophylaxis in orthopedic surgery and explore the potential consequences associated with the inappropriate administration of antibiotics.

Abstract
BACKGROUND Postvertebroplasty infection (PVI) is a catastrophic complication after vertebroplasty (VP). Although the urinary tract has been considered as a source of infectious pathogens, whether asymptomatic bacteriuria (ASB) is a risk factors for PVI remains unknown. METHODS This retrospective study included 716 patients (207 males; 509 females) treated with VP for osteoporotic vertebral fractures in a single medical center between May 2015 and December 2019. Clinical symptoms, urinalysis results, and culture data were collected preoperatively to identify patients with ASB. The primary outcome was PVI at the index level during follow-up. Demographic data and laboratory test results were compared between the PVI and non-PVI groups. RESULTS The mean age of the cohort was 78.6 ± 9.6 (range, 63-106). The prevalence of ASB was 14.1%, with female predominance (63.4%). The overall PVI rate was 1.26% (9/716). The PVI group had more patients with ASB (4/9, 44.4%) than did the non-PVI group (97/707, 13.7%) (p = 0.027). The rate of ASB treatment was similar between the PVI and non-PVI groups (25% vs. 23.7%, respectively). No case of PVI was caused by the urine culture pathogen. Multivariate analysis identified the following risk factors for PVI: ASB (odds ratio [OR], 5.61; 95% CI, 1.14-27.66; p = 0.034), smoking (OR, 16.26; 95% CI, 2.58-102.65; p = 0.003), and malignancy (OR 7.27; 95% CI, 1.31-40.31; p = 0.023). CONCLUSION ASB was not uncommon among patients admitted for VP and should be considered a marker of relatively poor host immunity. Preoperative ASB, a history of malignancy, and smoking were identified as significant risk factors for PVI.

Abstract
The antibiotic-resistant bacterium Acinetobacter baumannii is a leading cause of hospital-associated infections. Despite surveillance and infection control efforts, new A. baumannii strains are regularly isolated from health care facilities worldwide. In a mouse model of urinary tract infection, we found that mice infected with A. baumannii displayed high bacterial burdens in urine for several weeks. Two months after the resolution of A. baumannii infection, inserting a catheter into the bladder of mice with resolved infection led to the resurgence of a same-strain urinary tract infection in ~53% of the mice within 24 hours. We identified intracellular A. baumannii bacteria in the bladder epithelial cells of mice with resolved infection, which we propose could act as a host reservoir that was activated upon insertion of a catheter, leading to a resurgent secondary infection.

Abstract
INTRODUCTION Recent years have seen an increasing number of elective total knee (TKA) and hip arthroplasty (THA) procedures. Since a wide variety of methods and procedures are used in perioperative management, a survey-based study was carried out to identify the patterns of practice in Polish hospitals. MATERIAL AND METHODS With the help of the LimeSurvey application, questionnaires for anaesthesio-logists and orthopaedists were prepared to gain insight into the preparation of patients for TKA and THA procedures and perioperative care. Questionnaires included both single and multiple-choice questions concerning among other things type of laboratory tests, additional examinations and consultations performed on a routine basis before elective TKA and THA procedures. RESULTS A total of 162 medical centres took part in the study. Questionnaire responses were obtained from 93 (57%) orthopaedics teams and 112 (69%) anaesthesiology teams. A mean (standard deviation, SD) of 7.2 (3.5) laboratory tests are routinely ordered before surgery. For example, 47% of orthopaedists and 20% of anaesthesiologists order urinalysis, while 53% of orthopaedists and 26% of anaesthesiologists order a CRP test. Seventy-nine per cent of orthopaedists refer patients for at least one specialist consultation before the procedure. Dental consultation is requested by 40%, gynaecological consultation by 27%. Patient preoperative education is provided by 85% of orthopaedists and preoperative rehabilitation is prescribed by 46% of them. A total of 56% surveyed anaesthesiologists perform pre-anaesthetic evaluation upon patients' hospital admission. CONCLUSIONS The study found that the number of examinations and specialist consultations conducted in Polish hospitals exceeded the scope of recommendations of scientific societies. Furthermore, the authors identified a need to standardise perioperative management in the form of Polish guidelines or recommendations, with the intention to improve patient safety and optimize health care expenses.

Abstract
BACKGROUND The importance of preoperative urinary tract infection (UTI) in total hip and knee arthroplasty (THA and TKA) is controversial. The purpose of this study was to investigate the timing of preoperative UTI diagnosis and association with prosthetic joint infection (PJI) and determine if antibiotics impact this risk. METHODS A national database was used to analyze patients undergoing THA and TKA diagnosed with a preoperative UTI. Timing of diagnosis was categorized by 1-week intervals prior to surgery. Matched cohorts without UTI were collected, and PJI rates within 2 years of surgery were compared. Patients who received antibiotic prescriptions were identified and compared to no prescription. RESULTS Preoperative UTI within 1 week of TKA was associated with higher rates of PJI (odds ratio [OR] 1.34, 95% confidence interval [CI] 1.26-1.43, P < .001). Preoperative UTI within 1 week of THA (OR 1.56, 95% CI 1.44-1.68, P < .001) and between 1-2 weeks prior to THA (OR 1.12, 95% CI 1.02-1.22, P = .022) was associated with significantly higher rates of PJI. UTI diagnosis at any other time interval did not reach statistical significance. Antibiotic prescription was not associated with lower rates of PJI. CONCLUSION Patients with preoperative UTI within 1 week of TKA or within 2 weeks of THA have an increased risk of postoperative PJI. Antibiotics do not appear to mitigate risk.

Abstract
Background Surgical site infection following joint replacement surgery is still a significant complication, resulting in repeated surgery, prolonged antibiotic therapy, extended postoperative hospital stay, periprosthetic joint infection, and increased morbidity and mortality. This review discusses the risk factors associated with surgical site infection. Related risk factors The patient-related factors include sex, age, body mass index (BMI), obesity, nutritional status, comorbidities, primary diagnosis, living habits, and scores of the American Society of Anesthesiologists physical status classification system, etc. Surgery-related factors involve preoperative skin preparation, prolonged duration of surgery, one-stage bilateral joint replacement surgery, blood loss, glove changes, anti-microbial prophylaxis, topical anti-bacterial preparations, wound management, postoperative hematoma, etc. Those risk factors are detailed in the review. Conclusion Preventive measures must be taken from multiple perspectives to reduce the incidence of surgical site infection after joint replacement surgery.

Elimination of Routine Urinalysis before Elective Orthopaedic Surgery Reduces Antibiotic Utilization without Impacting Catheter-associated Urinary Tract Infection or Surgical Site Infection Rates. Hip Pelvis 2021; 33:225-230. [PMID: 34938692 PMCID: PMC8654593 DOI: 10.5371/hp.2021.33.4.225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Revised: 03/18/2021] [Accepted: 03/29/2021] [Indexed: 11/24/2022] Open
Abstract
Purpose Routine preoperative urinalysis has been the standard of care for the orthopedic population for decades, regardless of symptoms. Studies have demonstrated antibiotic overuse and low concordance between bacteria cultured from the surgical wound and the urine. Testing and treatment of asymptomatic urinary tract colonization before total joint arthroplasty (TJA) is unnecessary and increases patient risk. We investigated reducing antibiotic use by (1) modifying testing algorithms to target patients at risk, (2) modifying reflex to culture criteria, and (3) providing treatment guidelines. Materials and Methods A pre-post study was conducted to determine identify the impact of eliminating universal urinalysis prior to TJA on surgical site infection (SSI) and catheter-associated urinary tract infection (CAUTI) rates and number of antibiotic prescriptions. Patients who underwent primary hip or knee TJA or spinal fusions from February 2016 to March 2018 were included. Patient data was collected for pre- and post-practice change period (February 2016-October 2016 and August 2017-March 2018). Patient demographics, urinalysis results, cultures, and prescriptions were analyzed retrospectively from every tenth chart in the pre-period and prospectively on all patients in the post-period. Results A total of 4,663 patients were studied. There was a 96% decrease in urinalyses performed (P<0.0001), and a 93% reduction rate in antibiotic utilization (P<0.001). No significant difference in SSI and CAUTI rates was observed (P>0.05). Conclusion The elimination of routine urinalysis before orthopedic surgery resulted in a reduction in antibiotic utilization with no significant change in the SSI or CAUTI rates. Cost savings resulted from reduced antibiotic usage.

Abstract
Current strategies of combating bacterial infections are limited and involve the use of antibiotics and preservatives. Each of these agents has generally inadequate efficacy and a number of serious adverse effects. Thus, there is an urgent need for new antimicrobial drugs and food preservatives with higher efficacy and lower toxicity. Edible plants have been used in medicine since ancient times and are well known for their successful antimicrobial activity. Often photosensitizers are present in many edible plants; they could be a promising source for a new generation of drugs and food preservatives. The use of photodynamic therapy allows enhancement of antimicrobial properties in plant photosensitizers. The purpose of this review is to present the verified data on the antimicrobial activities of photodynamic phytochemicals in edible species of the world’s flora, including the various mechanisms of their actions.

Abstract
Traditionally, urinary tract infections (UTIs) have been categorised as either uncomplicated or complicated in veterinary medicine, with treatment differing for the two categories. In human medicine, there is an additional category: Asymptomatic bacteriuria, which is the presence of bacteriuria without symptoms of infection. Escherichia coli (E.coli) is the most common bacterial species involved in UTIs in dogs. Clinical signs can be absent in dogs with complicated UTIs, and this has been likened to asymptomatic bacteriuria (ASB) in people and has been termed subclinical bacteriuria (SBU) with the treatment recommendations for SBU in dogs have been adapted from human recommendations. There is a shift in the current treatment of UTIs to help minimise the development of antimicrobial resistance. Routine screening of dogs with conditions that may predispose them to UTIs has been discouraged as has the treatment of SBU. This has been due to the increase in antimicrobial resistance (AMR).

BMC Musculoskelet Disord 2021; 22:834. [PMID: 34587938 PMCID: PMC8480008 DOI: 10.1186/s12891-021-04725-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Accepted: 09/21/2021] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Current evidence does not recommend screening urine culture and curing asymptomatic bacteriuria (ASB) before joint arthroplasty. The bacteriuria count on pre-operative urinalysis is a more common clinical parameter. We aimed to investigate whether the bacteriuria count on preoperative urinalysis can increase postoperative wound complications in primary total hip arthroplasty (THA). METHODS We conducted a retrospective study that included patients who underwent primary THA in our institution from 2012 to 2018. We obtained preoperative urinalysis results before THA during the same hospitalization and identified patients with abnormal urinalysis. Receiver operating characteristic (ROC) curves were first generated to evaluate the predicted value of leukocyte esterase (LE), nitrite, bacteriuria, and pyuria in the urinalysis for superficial wound infection. Then, all included patients were divided into two groups according to the preoperative urinalysis: a bacteriuria-positive group and a bacteriuria-negative group. The primary outcome was the superficial wound infection rate within 3 months postoperatively, and the secondary outcomes included wound leakage, prosthetic joint infection (PJI), pulmonary infection, urinary tract infection (UTI), readmission rate within 3 months postoperatively, and length of stay (LOS) during hospitalization. We utilized univariable analyses to compare the outcomes between the two groups. A multivariable logistic regression model was generated to explore the potential association between bacteriuria and the risk of superficial wound infection, wound leakage, and readmission rate controlling for baseline values. RESULTS A total of 963 patients were included in the study. One hundred sixty patients had abnormal urinalysis. The AUCs for LE, nitrite, bacteriuria, and pyuria were 0.507 (95% confidence interval (CI), 0.315 to 0.698), 0.551 (0.347 to 0.756), 0.675 (0.467 to 0.882), and 0.529 (0.331 to 0.728), respectively. Bacteriuria was diagnostically superior to LE, nitrite, and pyuria. Among the 963 patients, 95 had a positive bacteriuria on preoperative urinalysis, and only 9 (9.5%) had a positive urine culture. Compared with the bacteriuria-negative group, the bacteriuria-positive group had a higher superficial wound infection rate (4.2% vs. 0.6%, P = 0.008), higher wound leakage rate (11.6% vs. 4.5%, P = 0.007), higher readmission rate (5.3% vs. 1.3%, P = 0.015) within 3 months postoperatively and longer LOS (6.19 ± 2.89 days vs. 5.58 ± 2.14 days, P = 0.011). After adjustment, the bacteriuria-positive group had a significantly increased risk of superficial wound infection (OR = 7.587, 95%CI: 2.002 to 28.755, P = 0.003), wound leakage (OR = 3.044, 95%CI: 1.461 to 6.342, P = 0.003), and readmission (OR = 4.410, 95%CI: 1.485 to 13.097, P = 0.008). CONCLUSION Preoperative bacteriuria positivity on urinalysis significantly increased the risk of postoperative wound complications, readmission, and LOS in primary THA regardless of the result of the urine culture. Urinalysis is a fast and cost-acceptable test whose advantages have been underestimated. LEVEL OF EVIDENCE Level III, observational study.

Abstract
Because of the negative side-effects of synthetic preservatives, the naturally-occurring polyphenols aroused intense interest of researchers. It has been suggested that chlorogenic acid (CA) and isochlorogenic acid A (iso-CAA) were good candidates to replace the synthetic preservatives. Moreover, the bactericidal activity of iso-CAA was stronger than CA, and the anti-bacterial activities of iso-CAA and CA were highly membrane-dependent. However, the mechanisms were still unclear. Therefore, in the present study, we investigated the mechanisms of the interactions between the two polyphenols and lipid bilayers through molecular dynamics simulations. The results revealed that iso-CAA could be inserted much deeper into POPG lipid bilayer than CA. We also found that hydrophobic interactions and hydrogen bonds both contributed to the insertion of iso-CAA into the POPG lipid bilayer, and the quinic acid moiety was the key structure in iso-CAA to form hydrogen bonds with POPG lipid bilayer. We believed that these findings would provide more useful information to explain the stronger bactericidal activity of iso-CAA than CA at the atomic level.

Abstract
The main goal of this study was to chemically characterize an aqueous S. nigra flower extract and validate it as a bioactive agent. The elderflower aqueous extraction was performed at different temperatures (50, 70 and 90 °C). The extract obtained at 90 °C exhibited the highest phenolic content and antiradical activity. Therefore, this extract was analyzed by GC-MS and HPLC-MS, which allowed the identification of 46 compounds, being quercetin and chlorogenic acid derivatives representative of 86% of the total of phenolic compounds identified in hydrophilic fraction of the aqueous extract. Naringenin (27.2%) was the major compound present in the lipophilic fraction. The antiproliferative effects of the S. nigra extract were evaluated using the colon cancer cell lines RKO, HCT-116, Caco-2 and the extract’s antigenotoxic potential was evaluated by the Comet assay in RKO cells. The RKO cells were the most susceptible to S. nigra flower extract (IC50 = 1250 µg mL−1). Moreover, the extract showed antimicrobial activity against Gram-positive bacteria, particularly Staphylococcus aureus and S. epidermidis. These results show that S. nigra-based extracts can be an important dietary source of bioactive phenolic compounds that contribute to health-span improving life quality, demonstrating their potential as nutraceutical, functional foods and/or cosmetic components for therapeutic purposes.

Abstract
BACKGROUND Surgical and host factors predispose patients to periprosthetic joint infection (PJI) after primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). While surgical factors are modifiable, host factors can be challenging, and there are limited data demonstrating that preoperative patient optimization decreases risk of PJI. The goal of this study was to evaluate whether extended oral antibiotic prophylaxis reduces the one-year infection rate in high-risk patients. METHODS A total of 3855 consecutive primary THAs and TKAs performed between 2011 and 2019 at a suburban academic hospital with modern perioperative and infection-prevention protocols were retrospectively reviewed. Beginning in January 2015, a 7-day oral antibiotic prophylaxis protocol was implemented after discharge for patients at high risk for PJI. The percentage of high-risk patients diagnosed with PJI within 1 year was compared between groups that did and did not receive extended antibiotic prophylaxis. Univariate and logistic regression analyses were performed, with P ≤ .05 denoting statistical significance. RESULTS Overall 1-year infection rates were 2.26% and 0.85% after THA and TKA, respectively. High-risk patients with extended antibiotic prophylaxis had a significantly lower rate of PJI than high-risk patients without extended antibiotic prophylaxis (0.89% vs 2.64%, respectively; P < .001). There was no difference in the infection rate between high-risk patients who received antibiotics and low-risk patients (0.89% vs 1.29%, respectively; P = .348) with numbers available. CONCLUSION Extended postoperative oral antibiotic prophylaxis for 7 days led to a statistically significant and clinically meaningful reduction in 1-year infection rates of patients at high risk for infection. In fact, the PJI rate in high-risk patients who received antibiotics was less than the rate seen in low-risk patients. Thus, extended oral antibiotic prophylaxis may be a simple measure to effectively counteract poor host factors. Moreover, the findings of this study may mitigate the incentive to select healthier patients in outcome-based reimbursement models. Further study with a multicenter randomized control trial is needed to further validate this protocol. LEVEL OF EVIDENCE Therapeutic level III.

Abstract
Background/aim Oral antibiotics are usually used to treat asymptomatic bacteriuria during the perioperative period of joint replacement. However, there is no unified conclusion as to whether asymptomatic bacteriuria causes infection around joint prostheses, and the efficacy of antibiotics is unknown. Materials and methods We systematically searched PubMed, CNKI, Ovid, Cochrane Library, EMBASE, manual research, and references of relevant articles up to January 1, 2020, to identify and compare observational studies. The Cochrane systematic review method was used, and Review Manager 5.3 software was used for analysis. Results Nine articles were included in the analysis, involving 29,844 cases of joint arthroplasty and 2366 cases of asymptomatic bacteriuria. Periprosthetic joint infection had a significantly higher incidence in the asymptomatic bacteriuria group than in the nonasymptomatic bacteriuria group (Odds Ratio: OR = 3.15, 95% CI: 1.23–8.02, P = 0.02). Seven of the nine articles reported the use of antibiotics for treating perioperative asymptomatic bacteriuria and there was no significant difference in the incidence of periprosthetic joint infection between the two groups (OR = 1.64, 95% CI: 0.84–3.23, P = 0.15). Conclusion The occurrence of asymptomatic bacteriuria in the perioperative period of joint arthroplasty is a risk factor for periprosthetic joint infection, and the use of antibiotics for asymptomatic bacteriuria does not change the rate of incidence.

Abstract
PURPOSE To evaluate preoperative asymptomatic bacteriuria (ASB) treatment to reduce early-periprosthetic joint infections (early-PJIs) after hip hemiarthroplasty (HHA) for fracture. METHODS Open-label, multicenter RCT comparing fosfomycin-trometamol versus no intervention with a parallel follow-up cohort without ASB. PRIMARY OUTCOME early-PJI after HHA. RESULTS Five hundred ninety-four patients enrolled (mean age 84.3); 152(25%) with ASB (77 treated with fosfomycin-trometamol/75 controls) and 442(75%) without. Despite the study closed without the intended sample size, ASB was not predictive of early-PJI (OR: 1.06 [95%CI: 0.33-3.38]), and its treatment did not modify early-PJI incidence (OR: 1.03 [95%CI: 0.15-7.10]). CONCLUSIONS Neither preoperative ASB nor its treatment appears to be risk factors of early-PJI after HHA. ClinicalTrials.gov Identifier: Eudra CT 2016-001108-47.

Abstract
We review antibiotic and other prophylactic measures to prevent periprosthetic joint infection (PJI) after hip hemiarthroplasty (HHA) surgery in proximal femoral fractures (PFFs). In the absence of specific guidelines, those applied to these individuals are general prophylaxis guidelines. Cefazolin is the most widely used agent and is replaced by clindamycin or a glycopeptide in beta-lactam allergies. A personalized antibiotic scheme may be considered when colonization by a multidrug-resistant microorganism (MDRO) is suspected. Particularly in methicillin-resistant Staphylococcus aureus (MRSA) colonization or a high prevalence of MRSA-caused PJIs a glycopeptide with cefazolin is recommended. Strategies such as cutaneous decolonization of MDROs, mainly MRSA, or preoperative asymptomatic bacteriuria treatment have also been addressed with debatable results. Some areas of research are early detection protocols in MDRO colonizations by polymerase-chain-reaction (PCR), the use of alternative antimicrobial prophylaxis, and antibiotic-impregnated bone cement in HHA. Given that published evidence addressing PJI prophylactic strategies in PFFs requiring HHA is scarce, PJIs can be reduced by combining different prevention strategies after identifying individuals who will benefit from personalized prophylaxis.

Abstract
Hintergrund Die Behandlung periprothetischer Infektionen (PPI) ist eine der größten Herausforderungen im Bereich der Endoprothetik. Der möglichst sichere Ausschluss oder die Bestätigung einer periprothetischen Infektion ist die Voraussetzung für jede Revisionsoperation und kann für den behandelnden Orthopäden und Unfallchirurgen eine große Herausforderung darstellen. Eine sichere evidenzbasierte präoperative Diagnostik ist im Sinne des Patienten notwendig, um einerseits eine periprothetische Infektion zu erkennen sowie die entsprechende chirurgische und antibiotische Therapie zu planen und andererseits unnötige zweizeitige Wechsel zu vermeiden. Ziel der Arbeit Ziel ist es, ein evidenzbasiertes problem- und prioritätenbasiertes Vorgehen zu entwickeln und dies in einem transparenten und standardisierten Algorithmus zusammenzufassen. Methode Durch systematische Literaturrecherche wurden relevante Arbeiten identifiziert und im Rahmen von Expertenrunden bewertet. Nach Extraktion der Daten erfolgte die Berechnung von Sensitivität, Spezifität, positiver und negativer Likelihood-Ratio sowie positiver und negativer prädiktiver Werte. Im Rahmen von 4 Treffen wurden die entsprechenden Studien der Arbeitsgruppe für implantatassoziierte Infektionen präsentiert und analog zu Standard-Delphi-Runden durch die einzelnen Experten bearbeitet und bewertet. Gemäß der Prioritätenliste der Expertenrunde erfolgte die Entwicklung eines zur ISO (International Organization for Standardisation) konformen Algorithmus. Ergebnisse Der entwickelte Algorithmus ist eine Abfolge von evidenzbasierten Prozessen gemäß der verwendeten ISO-Norm. Gemäß der durch die Expertenrunde priorisierten Haupt- und Nebenkriterien erfolgte die Entwicklung logisch strukturiert und problemorientiert. Schlussfolgerung Der Ausschluss einer periprothetischen Infektion ist von enormer Bedeutung vor einer Revisionsoperation und entscheidet in vielen Fällen über den Erfolg und die Invasivität der Operation. Die Diagnose „periprothetische Infektion“ erfordert eine substanzielle Veränderung der therapeutischen Strategie. Der durch die Arbeitsgruppe entwickelte Algorithmus fasst Positionen aus der aktuellen Literatur und spezielle Expertenmeinungen zusammen, dies ermöglicht einen transparenten diagnostischen Ansatz im Sinne einer Standard Operation Procedure.

Abstract
Every year, worldwide, millions of people suffering from joint pain undergo joint replacement. For most patients, joint arthroplasty reduces pain and improve function, though a small fraction will experience implant failure. One of the main reasons includes prosthetic joint infection (PJI), involving the prosthesis and adjacent tissues. Few microorganisms (MO) are required to inoculate the implant, resulting in the formation of a biofilm on its surface. Standard treatment includes not only removal of the infected prosthesis but also the elimination of necrotic bone fragments, local and/or systemic administration of antibiotics, and revision arthroplasty with a new prosthesis, immediately after the infection is cleared. Therefore, an alternative to the conventional therapeutics would be the incorporation of natural antimicrobial compounds into the prosthesis. Chitosan (Ch) is a potential valuable biomaterial presenting properties such as biocompatibility, biodegradability, low immunogenicity, wound healing ability, antimicrobial activity, and anti-inflammatory potential. Regarding its antimicrobial activity, Gram-negative and Gram-positive bacteria, as well as fungi are highly susceptible to chitosan. Calcium phosphate (CaP)-based materials are commonly utilized in orthopedic and dentistry for their excellent biocompatibility and bioactivity, particularly in the establishment of cohesive bone bonding that yields effective and rapid osteointegration. At present, the majority of CaP-based materials are synthetic, which conducts to the depletion of the natural resources of phosphorous in the future due to the extensive use of phosphate. CaP in the form of hydroxyapatite (HAp) may be extracted from natural sources as fish bones or scales, which are by-products of the fish food industry. Thus, this review aims to enlighten the fundamental characteristics of Ch and HAp biomaterials which makes them attractive to PJI prevention and bone regeneration, summarizing relevant studies with these biomaterials to the field.

Abstract
BACKGROUND Urinary catheter use in the peri- and post-operative phase following arthroplasty may be associated with urinary tract infection (UTI) and deep prosthetic joint infection (PJI). These can be catastrophic complications in joint arthroplasty. We performed a systematic review of the evidence on use of antibiotics for urinary catheter insertion and removal following arthroplasty. METHODS Electronic databases were searched using the Healthcare Databases Advanced Search interface. Grey literature was searched. From 219 citations, six studies were deemed eligible for review. Due to study heterogeneity, a narrative approach was adopted. Methodological quality of each study was assessed using the Critical Appraisal Skills Programme appraisal tool. RESULTS A total of 4696 hip and knee arthroplasties were performed on 4578 participants across all studies. Of these, 1475 (31%) were on men and 3189 (68%) on women. The mean age of study participants was 69 years. Three thousand four hundred and eighty-nine cases (74.3%) were related to hip arthroplasty and 629 (13.4%) to knee arthroplasty. Five hundred and seventy-eight (12.3%) were either hip or knee arthroplasty. Forty-five PJIs were reported across all studies (0.96%). Two studies found either no PJI or no statistical difference in the rate of PJI when no antibiotic prophylaxis was used for catheter manipulation. Another study found no statistical difference in PJI rates between patients with or without preoperative bacteriuria. Where studies report potential haematogenous spread from UTIs, this association can only be assumed. Increased duration of urinary catheterization is positively associated with UTI. CONCLUSION It remains difficult to justify the use of prophylactic antibiotics for catheter manipulation in well patients. Their use is not recommended for this indication.

Abstract
Background The aim of this study was to describe the clinical and microbiological characteristics of infective arthritis and to analyze risk factors for Gram-negative bacterial infections that cause infective arthritis. Materials and Methods Patients admitted between 2009 - 2018 with infective arthritis in a single-tertiary hospital were evaluated retrospectively. Results A total of 181 patients were enrolled in this study. Of them, 135 were native joint infection patients and 46 were prosthetic joint infection patients. The most common site of infective arthritis was the knee (63.6%), followed by the shoulder (17.7%), and the hip (9.9%). The most frequently identified microorganisms were Staphylococcus aureus (51.1%), followed by Streptococci sp. (21.1%), Enterobacteriaceae (8.4%), and coagulase-negative-Staphylococci (CNS; 8.4%). Infections due to Gram-negative bacteria and fungi made up 13.7% and 3.2% of all cases, respectively. Additionally, 20% and 4.2% of the cases involved methicillin-resistant S. aureus (MRSA) and MRCNS. We found that bacteriuria, infective arthritis in the hip, and steroid use at admission are independent risk factors for Gram-negative bacterial infections. Conclusion Infective arthritis with methicillin-resistant microorganisms reached up to about 25% in a single-tertiary hospital in Korea. In case of suspected urinary tract infection, infective arthritis of the hip joint, or steroid use at admission time among infective arthritis patients, empirical treatment covering Gram-negative microorganisms can be considered.

Using implementation science to develop and implement a guideline to reduce unnecessary preoperative testing for asymptomatic bacteriuria prior to elective arthroplasty. J Bone Jt Infect 2020; 6:57-62. [PMID: 33552879 PMCID: PMC7852403 DOI: 10.5194/jbji-6-57-2020] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Accepted: 10/01/2020] [Indexed: 11/11/2022] Open
Abstract
Introduction: Guidelines and consensus statements do not support routine preoperative testing for asymptomatic bacteriuria (ASB) prior to elective arthroplasty. Despite this, urine testing remains commonplace in orthopaedic practice. This mixed methods stepwise quality improvement project aimed to develop and implement a guideline to reduce unnecessary preoperative testing for asymptomatic bacteriuria prior to elective arthroplasty within a single centre. Methods: Step 1 - description of current practice in preoperative urine testing prior to arthroplasty within a single centre; Step 2 - examination of the association between preoperative urine culture and pathogens causing prosthetic joint infection (PJI); Step 3 - co-design of a guideline to reduce unnecessary preoperative testing for asymptomatic bacteriuria prior to elective arthroplasty; Step 4 - implementation of a sustainable guideline to reduce unnecessary preoperative testing for asymptomatic bacteriuria prior to elective arthroplasty. Results: Retrospective chart review showed inconsistency in mid-stream urine (MSU) testing prior to elective arthroplasty (49 % preoperative MSU sent) and in antimicrobial prescribing for urinary tract infection (UTI) and ASB. No association was observed between organisms isolated from urine and joint aspirate in confirmed cases of PJI. Co-design of a guideline and decision support tool supported through an implementation strategy resulted in rapid uptake and adherence. Sustainability was demonstrated at 6 months. Conclusion: In this stepwise study, implementation science methodology was used to challenge outdated clinical practice, achieving a sustained reduction in unnecessary preoperative urine testing for ASB prior to elective arthroplasty.

The Implementation of a Complication Avoidance Care Bundle Significantly Reduces Adverse Surgical Outcomes in Orthopedic Trauma Patients. J Clin Med 2020; 9:jcm9124006. [PMID: 33322347 PMCID: PMC7763652 DOI: 10.3390/jcm9124006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 12/02/2020] [Accepted: 12/08/2020] [Indexed: 11/29/2022] Open
Abstract
Background: Surgical complications are associated with a significant burden to patients and hospitals and are increasingly discussed in recent literature. This cohort study reviewed surgery-related complications in a Level I trauma center. The effect of a complication avoidance care bundle on the rate of surgical complications was analyzed. Methods: All complications (surgical and nonsurgical) that occur in our trauma department are prospectively captured using a standardized documentation form and are discussed and analyzed in a weekly trauma Morbidity and Mortality (M&M) conference. Surgical complication rates are calculated using the annual surgical procedure numbers. Based on discussions in the M&M conference, a complication avoidance care bundle consisting of five measures was established: (1) Improving team situational awareness; (2) reducing operating room traffic by staff members and limiting door-opening events; (3) preoperative screening for infectious foci; (4) adapted preoperative antibiotic prophylaxis in anatomic regions with a high risk of infectious complications; and (5) use of iodine-impregnated adhesive drape. Results: The number of surgical procedures steadily increased over the study years, from 3587 in 2015 to 3962 in 2019 (an increase of 10.5%). Within this 5-year study period, the overall rate of surgical complications was 0.8%. Surgical site infections were the most frequently found complications (n = 40, 24.8% of all surgical complications), followed by screw malposition (n = 20, 12.4%), postoperative dislocations of arthroplasties (n = 18, 11.2%), and suboptimal fracture reduction (n = 18, 11.2%). Following implementation of the complication avoidance care bundle, the overall rate of surgical complications significantly decreased, from 1.14% in the year 2016 to 0.56% in the study year 2019, which represents a reduction of 51% within a 3-year time period. Conclusions: A multimodal strategy targeted at reducing the surgical complication rate can be successfully established based on a transparent discussion of adverse surgical outcomes. The combination of the different preventive measures was associated with reducing the overall complication rate by half within a 3-year time period.

J Arthroplasty 2020; 35:2380-2385. [PMID: 32381445 DOI: 10.1016/j.arth.2020.04.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2020] [Revised: 03/16/2020] [Accepted: 04/06/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND The objective of this study is to evaluate urinary self-catheterization as a potential risk factor for postoperative complications following total hip (THA) and knee (TKA) arthroplasty procedures. METHODS Self-catheterization patients who underwent total joint arthroplasty from 2005 to 2014 were identified in a national insurance database. Rates of death, hospital readmission, emergency room visit, infection, revision, and dislocation for THA or arthrofibrosis for TKA were calculated, as well as cost and length of stay. Self-catheterizing patients were then compared to a 4:1 matched control cohort using a logistic regression analysis to control for confounding factors. RESULTS Sixty-nine patients underwent THA, and 128 patients who underwent TKA and who actively self-catheterized at the time of surgery were identified. Self-catheterization was not associated with infection, emergency room visits, readmissions, revision surgery, arthrofibrosis, or cost compared to the 4:1 matched control cohort. However, self-catheterization was associated with significantly longer length of stay (difference for THA = 1.91 days, confidence interval = 0.97-2.86, P < .001; difference for TKA = 0.61, odds ratio = 0.16-1.06, P = .01). CONCLUSION Self-catheterization does not appear to be associated with increased risk of major complications following total joint arthroplasty with the numbers available in this study. Reassurance can be given regarding concerns for infection and other complications following surgery in this patient population.

Abstract
OBJECTIVE To determine the prevalence of subclinical bacteriuria (SBU) in dogs with cranial cruciate ligament (CCL) disease, the clinical variables and clinicopathologic data associated with SBU, and the incidence of surgical site infections (SSI) in dogs with and without SBU. STUDY DESIGN Prospective, clinical cohort study. ANIMALS One hundred fifty-five dogs with CCL disease. METHODS Dogs had a urinalysis, sediment examination, and aerobic urine culture performed. Age, breed, sex, body weight, body condition score, clinical history, and physical examination findings were recorded. Dogs with SBU were not treated for bacteriuria or with postoperative antibiotics. Standard perioperative antimicrobials were provided for all dogs. Dogs that received nonsteroidal anti-inflammatory drugs were not excluded. Dogs that underwent an osteotomy were followed for at least 1 year to determine incidence of SSI. Outcomes and variables associated with SBU were assessed. RESULTS In 155 dogs with CCL disease, the prevalence of SBU was 6.5%, and SBU occurred exclusively in female dogs (11.4%). The incidence of SSI was 22.3% (25/112). Two of six dogs with SBU and 23/106 dogs without SBU developed SSI. Organisms isolated from SSI were different from those isolated from urine. CONCLUSION The prevalence of SBU in dogs with CCL disease was similar to that in other studies in which SBU was evaluated in various populations of dogs. CLINICAL SIGNIFICANCE Screening for and treatment of SBU may not be beneficial prior to tibial osteotomy for CCL disease. Additional studies are required to determine whether dogs with SBU have a greater risk of SSI.

Abstract
Asymptomatic bacteriuria (ASB) is a common finding in many populations, including healthy women and persons with underlying urologic abnormalities. The 2005 guideline from the Infectious Diseases Society of America recommended that ASB should be screened for and treated only in pregnant women or in an individual prior to undergoing invasive urologic procedures. Treatment was not recommended for healthy women; older women or men; or persons with diabetes, indwelling catheters, or spinal cord injury. The guideline did not address children and some adult populations, including patients with neutropenia, solid organ transplants, and nonurologic surgery. In the years since the publication of the guideline, further information relevant to ASB has become available. In addition, antimicrobial treatment of ASB has been recognized as an important contributor to inappropriate antimicrobial use, which promotes emergence of antimicrobial resistance. The current guideline updates the recommendations of the 2005 guideline, includes new recommendations for populations not previously addressed, and, where relevant, addresses the interpretation of nonlocalizing clinical symptoms in populations with a high prevalence of ASB.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE Compare postoperative infection rates and 30-day outcomes in spine surgery patients with and without a preoperative urinary tract infection (UTI). SUMMARY OF BACKGROUND DATA There is mixed evidence regarding safety and risks when operating on spine patients with a preoperative UTI. METHODS Using data from the American College of Surgeons National Surgical Quality Improvement Program, we identified all adult patients undergoing spine surgery between 2012 and 2017 with a preoperative UTI. Patients with other preoperative infections were excluded. Our primary outcome was any postoperative infection (pneumonia, sepsis, surgical site infection, and organ space infection). Our secondary outcomes included surgical site infections, non-infectious complications, return to operating room, and 30-day readmission and mortality. We used univariate, then multivariate Poisson regression models adjusted for demographics, comorbidities, laboratory values, and case details to investigate the association between preoperative UTI status and postoperative outcomes. RESULTS A total of 270,371 patients who underwent spine surgery were analyzed. The most common procedure was laminectomy (41.9%), followed by spinal fusion (31.7%) and laminectomy/fusion (25.6%). Three hundred fourty one patients had a preoperative UTI (0.14%). Patients with a preoperative UTI were more likely to be older, female, inpatients, emergency cases, with a higher American Society of Anesthesiologists score, and a longer operating time (for all, P < 0.001). Patients with a preoperative UTI had higher rates of infectious and non-infectious complications, return to operating room, and unplanned readmissions (for all, P < 0.001). However, there was no significant difference in mortality (0.6% vs. 0.2%, P = 0.108). Even after controlling for demographics, comorbidities, labs, and case details, preoperative UTI status was significantly associated with more postoperative infectious complications (incidence rate ratio [IRR]: 2.88, 95% confidence interval [CI]: 2.25-3.70, P < 0.001). CONCLUSION Preoperative UTI status is significantly associated with postoperative infections and worse 30-day outcomes. Spine surgeons should consider delaying or cancelling surgery in patients with a UTI until the infection has cleared to reduce adverse outcomes. LEVEL OF EVIDENCE 3.

Abstract
PURPOSE Urinary tract infection (UTI) are very common in the general population, however it is unclear whether UTI is a risk factor of prosthetic joint infection (PJI). Our purposes were: (1) To determine whether UTI is a risk factor of PJI after joint replacement, and (2) to determine whether the microorganisms causing PJI and UTI are the same. METHODS PubMed, Web of Science, the Cochrane Library, and EMBASE were searched systematically for studies. The effect sizes of RR were calculated for included studies that reported raw counts with 95% CIs. The aim 1 of the study is a meta-analysis; the aim 2 is a systematic review. RESULTS The aim 1 indicated that the risk of PJI was significantly higher in the UTI group than in the control group (RR = 3.17; 95% CI, 2.19-4.59). The aim 2 indicated that the microorganisms of UTI and PJI were the same in the same patient, and these included Enterococcus faecalis, and Pseudomonas, which supports the theory of PJI occurring via the haematogenous route from the genitourinary tract that harbours bacteria in UTI. CONCLUSION This study identified UTI as being significantly associated with PJI after joint arthroplasty and PJI occurring via the haematogenous route from the genitourinary tract harbouring bacteria in UTI. Therefore, postponing surgery and even treating patients with known UTI preoperatively are recommended.

Abstract
BACKGROUND Although empiric treatment of urinary tract colonized patients remains a frequent practice in neurosurgery, the value of this practice remains debatable. OBJECTIVE To analyze the effect of screening and treatment of bacteriuria on surgical site infections, incidence of Clostridium difficile, and mortality in neurosurgical trauma patients. METHODS Database queries and direct patient chart reviews were used to gather patient chart data. T-tests, chi-square tests, binary logistic regressions, and propensity matched cohorts comparisons were performed. RESULTS A total of 3563 admitted neurosurgical trauma patients were identified over an 8 yr period (1524 cranial, 1778 spinal, and 261 combined craniospinal diagnoses). Nine hundred ninety-one patients underwent an operative neurosurgical procedure. Urinalysis was significantly associated with antibiotics exposure in both operative and nonoperative patients (P < .001). Operative patients treated with empiric antibiotics did not have a reduced risk of wound infection (P = .21), including in a propensity matched cohort (P = .52). Patients treated with empiric antibiotics had significantly increased rates of C. difficile infection (P < .001). At last follow-up, neurosurgical trauma patients that developed C. difficile had an increased risk of death (P < .005); antibiotic exposure and death were also significantly associated (P = .018). The association of C. difficile with empiric antibiotics remained significant in a propensity-matched cohort (P = .0024). CONCLUSION The routine use of urinalysis and empiric urinary antibiotics for bacteriuria in neurosurgical trauma patients without urinary symptoms increases risk of exposure to antibiotics does not decrease rates of wound infection, and is associated with increased rates of C. difficile infection and death.

Abstract
PURPOSE Antibiotic prophylaxis is routinely used in the surgical management of proximal femur fractures. The role of bacterial colonization of the skin and urine in the development of deep surgical site infections (SSI) is yet to be elucidated. This study aimed to evaluate the role of previous skin and urine colonization in the development of deep SSI after a proximal femoral fracture surgery. METHODS We conducted a prospective observational study in 326 patients > 64 years old, who were scheduled to surgery. Cultures from skin samples of the surgical site and from urine were performed prior to the procedure, and cefazoline was administered as prophylaxis. RESULTS Skin microbiota was isolated in 233 (71.5%) cases; 8 (2.5%) samples were positive for other bacteria, and 85 (26%) were negative. Of 236 urine samples, 168 were negative or contaminated (71.2%), and 68 (28.8%) were positive, being 58/236 for Enterobacterales (24.6%). Acute deep SSI were diagnosed in nine out of 326 patients (2.7%), and two (22%) were infected by Gram-negative bacilli. Of the 9 cases, normal skin microbiota was isolated in 7 (78%), and the remaining two were negative. Seven cases had negative or contaminated urine cultures, and the one with E. coli did not correlate with SSI bacteria. CONCLUSION In our elderly hip fracture population, most patients harbored normal skin microbiota, and Enterobacterales urine cultures were positive in one-quarter of cases. There was no relationship between skin colonization, urine culture, and deep SSI. We therefore do not believe that our patients would benefit from modifying the current antibiotic prophylaxis.

Abstract
OBJECTIVE To determine the risk factors associated with prosthetic knee infection in elderly patients in a referral hospital in Peru. PATIENTS AND METHODS A case and control study was performed. The calculated sample was 44 cases and 132 controls. The data were collected retrospectively from clinical records. U-Mann Whitney and Chi-square tests were performed in the comparison of cases and controls. Odds ratios (OR) were calculated in a binary logistic regression analysis to identify the risk factors, a P<.05 and a 95% confidence interval (CI) were considered significant. RESULTS Significant (P<.05) risk factors evidenced in the bivariate analysis were obesity (OR=9.72; 95%CI: 4.47-21.14), smoking (OR=4.06; 95%CI: 1.59-10.39), rheumatoid arthritis (OR=4.66; 95%CI: 1.52-14.32), diabetes mellitus type2 (OR=5.63; 95%CI: 2.69-11.78), persistent drainage (OR=9.27; 95%CI: 3.85-22.31), superficial infection (OR=6.87; 95%CI: 3.25-14.49) and prolonged hospital stay (OR=4.67; 95%CI: 2.26-9.64). In the multivariate analysis where it was adjusted for confounding variables, it was determined that risk factors were obesity (ORa=9.14; 95%CI: 3.28-25.48), diabetes mellitus (ORa=3.77; 95%CI: 1.38-10.32), persistent drainage (ORa=4.64; 95%CI: 1.03-20.80) and superficial wound infection (ORa=27.35; 95%CI: 2.57-290.64). CONCLUSIONS Risk factors for prosthetic knee infection identified in this study are preventable. The main risk factors were obesity, diabetes mellitus type2, superficial wound infection and persistent drainage, which were considered together or separately to be risk factors in the population studied.

Abstract
Background Periprosthetic joint infection (PJI) is a rare but devastating complication after total joint arthroplasty. There is a paucity of data on the incidence and prevalence of periprosthetic infection in mainland China. This study aimed to analyze the rates of surgical revision after arthroplasty due to PJI and the procedures followed in Beijing, China. Methods The study involved a retrospective multicenter cross-sectional survey of patients undergoing revisions for periprosthetic infection after hip/knee arthroplasty at nine hospitals in Beijing from 2014 to 2016. Age, gender, body mass index, primary diagnosis, comorbidity, primary surgery, treatment methods, and post-revision complications were analyzed. Results A total of 38,319 hip/knee arthroplasties and 366 (0.96%) revisions for PJI were identified. Of these, 161 (161/14,110; 1.14%) revisions involved hip arthroplasty, whereas 205 (205/24,209; 0.85%) revisions were due to knee arthroplasty. Procedures for revisions of infected hip included 7 (4.3%) cases of open debridement and prosthesis retention, 32 (19.9%) cases of one-stage exchange, 121 (75.2%) cases of two-stage exchange, and 1 (0.007%) case of hip dissection. As for the infected knee, the procedures included 45 (22.0%) cases of open debridement and prosthesis retention, 13 (6.3%) cases of one-stage exchange, 143 (69.8%) cases of two-stage exchange, and 4 (0.02%) cases of knee fusion. Conclusions The study found the rates of revision due to PJI to be low. Nonetheless, the incidence of PJI in mainland China could be higher and calls for more elaborate studies in geographically and socioeconomically diverse health institutions.

Risk of infection in patients undergoing urologic surgery based on the presence of asymptomatic bacteriuria: A prospective study. Am J Infect Control 2019; 47:1474-1478. [PMID: 31375294 DOI: 10.1016/j.ajic.2019.06.024] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2019] [Revised: 06/18/2019] [Accepted: 06/19/2019] [Indexed: 11/24/2022]
Abstract
BACKGROUND Treatment of asymptomatic bacteriuria (ASB) is recommended in pregnant women and prior to urologic procedures with anticipated mucosal disruption. However, there is still insufficient evidence of the usefulness of treating ASB prior to urologic procedures. Therefore, the aim of this study was to ascertain the risk of infections in patients undergoing urologic surgery based on the presence of ASB. METHODS We conducted a cohort study among patients undergoing urologic surgery at a single center located in Medellín, Colombia. All patients were screened for ASB prior to their procedures. Patients were evaluated for the development of any postoperative infectious complications for up to 30 days after the procedure. RESULTS A total of 149 patients were included in this cohort. Incidence of ASB was 14.8%. Thirteen patients (8.72%) developed infectious complications: 3 (13.64%) with ASB and 10 (7.87%) without ABS. Factors associated with postoperative infectious complications included urologic cancers (hazard ratio [HR], 5.26; 95% confidence intervals [CI], 1.24-22.37), urologic interventions in the preceding 3 months (HR, 3.72; 95% CI, 1.02-13.51), and use of antibiotics 3 months prior to surgery (HR, 3.83; 95% CI, 1.01-15.49). Presence of ASB was not associated with postsurgical infectious complications (HR, 1.02; 95% CI, 0.26-3.96). CONCLUSIONS There was no association between ASB and postoperative infectious complications. There were other factors associated with infectious complications, such as urologic cancer, previous history of urologic manipulation, and antibiotic use.

Abstract
BACKGROUND Although the factors associated to bacterial resistance in patients with asymptomatic bacteriuria (ASB) have been studied in pregnant, fertile age women, patients with spinal cord injury, and those with urogynecological disorders, nothing is known about the factors associated with multidrug-resistant (MDR) bacteria in patients with ASB and planned urological procedures. This study therefore sought to identify the sociodemographic and clinical factors associated with MDR bacteria in a cohort of patients with ASB scheduled for urological procedures. METHODS We conducted a nested case-control study on a cohort of patients with ASB and planned urological procedures at 3 Colombian medical centers. Cases were patients with MDR bacteria and controls were patients without MDR bacteria. RESULTS A total of 184 patients were included, 41.8% (n = 77) of whom presented ASB with MDR bacteria. The factors linking ASB with MDR bacteria were: advanced age (odds ratio, 1.03; 95% confidence interval, 1.01-1.06) and hospitalization within the 3-month period before surgery (odds ratio, 2.35; 95% confidence interval, 1.08-5.21). CONCLUSIONS Bacterial resistance is frequent among patients with ASB and planned urological procedures. Advanced age and prior hospitalization should be borne in mind for patients with planned urological procedures because they are factors associated with the presence of MDR bacteria.

Abstract
Introduction Arthroplasty has always been associated with complications, such as the possibility of periprosthetic infection. The presence of an active infection at the site of the planned surgery is considered a contraindication for the new implant. However, it is unclear whether there is an association between the presence of remote musculoskeletal infection and the development of infection in the prosthetic joint itself. We report six cases involving patients with active ongoing musculoskeletal infections at a remote site who underwent arthroplasty. Presentation of cases Four male and two female patients were included in this review. Three patients underwent total hip arthroplasty, one underwent hip hemiarthroplasty, and two underwent total knee arthroplasty. All surgeries were performed in the presence of different stages of infection at a remote site; two had active infections with pus-discharging sinus, one was being treated with long-term oral antibiotic suppression, and three patients were diagnosed with remote prosthetic joint infections on the basis of joint aspiration or intraoperative cultures. Clinical assessments of pain, wound erythema or drainage, and soft tissue swelling were performed at follow-up. Radiography and analysis of inflammatory marker levels were performed preoperatively and 6 weeks postoperatively. Discussion All six patients were followed-up for at least 18 months (mean, 4.6 years; range, 18 months to 9 years). No evidence of superficial surgical-site infection or deep prosthetic joint infection was observed. Conclusion The presence of an active infection at a remote site might not be a contributing factor to periprosthetic joint infection. Six patients underwent arthroplasty in presence of active remote-site infections. No evidence of superficial surgical-site infection was seen (18-month follow-up). No evidence of deep prosthetic joint infection was observed (18-month follow-up). Active remote-site infection is not associated with periprosthetic joint infection.

Abstract
BACKGROUND Prosthetic joint infection (PJI) is a serious complication after total joint arthroplasty, and prevention is of great importance. The genitourinary tract is a potential source of bacterial seeding and one that can be easily managed. Despite little supportive evidence, routine urine screening and subsequent treatment before elective surgery in patients without symptoms has found its way into clinical practice in many countries. This systematic review and meta-analysis aims to ascertain whether asymptomatic bacteriuria (ASB) is a risk factor for PJI and if so, whether preoperative antibiotic treatment is effective in reducing its risk. METHODS PubMed, Ovid Medline, and Cochrane databases were searched using a systematic strategy. Selection of papers was exclusive to include only those which offered information about PJI rate specifically in patients with or without asymptomatic abnormal urinalysis or bacteriuria and/or information on whether ASB patients were preoperatively treated with antibiotics or not to be included in the analysis. RESULTS Six-hundred sixty-three papers were screened, and 10 papers were ultimately included (28,588 patients). Results show an increased risk of developing PJI among ASB patients (odds ratio = 3.64, 95% confidence interval = 1.40-9.42). However, most PJI microorganisms are unrelated to those previously found in the urine and preoperative antibiotic therapy does not influence PJI risk (odds ratio = 0.98, 95% confidence interval = 0.39-2.44). CONCLUSION Routine urinary screening prior to elective total joint arthroplasty and treatment of asymptomatic patients is not recommended.

Abstract
Periprosthetic joint infection (PJI) is one of the most serious complications after total joint arthroplasty (TJA). The prevalence of urinary tract infection (UTI) is common, particularly among elderly women, a group for whom TJA may be required. The association between preoperative UTI and increased risk of PJI after TJA is unclear. We reviewed key articles concerning the relationship between UTIs and PJI, and summarized recommendations of international consensus on PJI, which was established in Philadelphia in July of 2018. In addition, we distinguish between symptomatic UTI and asymptomatic bacteriuria, because their causative effects on PJI are quite different.
