Review
The aim of this study was to determine the risk factors for postoperative infection after spinal surgery, in order to prevent its occurrence. We searched the Pubmed, Embase, and Cochrane library databases, and identified 25 case-control studies. The pooled results revealed that the major factors associated with infection were diabetes mellitus (odds ratio [OR] 2.04; 95% confidence interval [CI] 1.69-2.46), obesity (OR 2.13; 95% CI 1.55-2.93), smoking (OR 1.17; 95% CI 1.03-1.32), urinary tract infection (OR 3.19; 95% CI 1.68-6.06), hypertension (OR 1.67; 95% CI 1.26-2.22), transfusion (OR 3.64; 95% CI 2.60-5.08), and cerebrospinal fluid leak (OR 3.22; 95% CI 1.07-9.67). There was insufficient evidence to suggest that male sex, age, alcohol use, and steroid use increased the incidence of infection after spinal surgery. Our analyses suggest strategies to prevent surgical site infection. However, the results should be interpreted with caution because of heterogeneity amongst the included studies.

Meta-Analysis Review
Probiotics were used for liver transplantation (LT) patients to reduce postoperative infection, but clinical trials examining the combined use of prebiotics and probiotics are limited. This meta-analysis aimed to compare the safety and efficacy of combined use of prebiotics and probiotics in patients undergoing LT. PubMed, Cochrane, and Embase databases were reviewed for the combined use of prebiotics and probiotics in patients undergoing LT. The weighted mean difference (WMD), risk ratio (RR), and 95% CI were calculated. A total of 6 related studies comprising 345 patients were included. Most prebiotics and probiotics were given for 7.14 days. The overall infection rate (RR = 0.29; 95% CI, 0.14.0.60; P value for heterogeneity [P ] = .066; test for heterogeneity [I ] = 51.7%) and the incidence of urinary tract infection (RR = 0.14; 95% CI, 0.04-0.47, P = .724; I = 0%) were lower in the probiotics group when compared with those in the control group. Furthermore, probiotics significantly reduced the hospital length of stay (WMD = -1.37; 95% CI, -1.92 to 0.82; P = .506; I = 0%) and the duration of antimicrobial therapy (WMD = -4.31; 95% CI, -5.41 to 3.22; P = .019; I = 69.8%) in patients undergoing LT. These findings suggested that the combined use of prebiotics and probiotics (Lactobacillus and Bifidobacterium) was effective in lowering the incidence of bacterial infections and shortening the hospital length of stay and duration of antibiotic therapy in patients undergoing LT, when compared with conventional nutrition.

Review
CONTEXT
Patients undergoing radical cystectomy frequently suffer from infectious complications, including urinary tract infections (UTIs) and surgical site infections (SSIs) leading to emergency department visits, hospital readmission, and added cost.
OBJECTIVE
To summarize the literature regarding perioperative antibiotic prophylaxis, ureteric stent usage, and prevalence of infectious complications after cystectomy.
EVIDENCE ACQUISITION
A systematic review of PubMed/Medline, EMBASE, Cochrane Library, and reference lists was conducted.
EVIDENCE SYNTHESIS
We identified 20 reports including a total of 55 306 patients. The median rates of any infection, UTIs, SSIs, and bacteremia were 40%, 20%, 11%, and 6%, respectively. Perioperative antibiotic prophylaxis differed substantially between reports. Perioperative antibiotics were used only during surgery in one study but were continued over several days after surgery in all other studies. Empirical use of antibiotics for 1-3 d after surgery was described in 12 studies, 3-10 d in two studies, and >10 d in four studies. Time to stent removal ranged from 4 to 25 d after cystectomy. Prophylactic antibiotics were used before stent removal in nine of 20 studies; two of these studies used targeted antibiotics based on urine cultures from the ureteric stents, and the other seven studies used a single shot or 2 d of empirical antibiotics. Studies with any prophylactic antibiotic before stent removal found a lower median percentage of positive blood cultures after stent removal than studies without prophylactic antibiotics before stent removal (2% vs 9%).
CONCLUSIONS
We confirmed a high proportion of infectious complications after cystectomy, and a heterogeneous pattern of choice and duration of antibiotics during and after surgery or stent removal. These findings highlight a need for further studies and support quality prospective trials.
PATIENT SUMMARY
In this review, we observed wide variability in the use of antibiotics before or after surgical removal of the bladder.

Meta-Analysis Review
Procalcitonin is a serologic marker that increases in response to inflammatory stimuli, especially those of bacterial origin. Postoperative orthopedic periprosthetic infections are often difficult to diagnose. This study systematically reviewed the literature to evaluate the statistical measures of performance of procalcitonin as a marker of postoperative orthopedic infection. This study showed that procalcitonin has a weighted pooled sensitivity of 67.3%, specificity of 69.4%, positive likelihood ratio of 1.778, negative likelihood ratio of 0.423, and diagnostic odds ratio of 5.770. These results illustrate that procalcitonin is an effective serologic marker for postoperative bacterial infections. [Orthopedics. 2018; 41(3):e303-e309.].

Review
BACKGROUND
Modern management of human immunodeficiency virus (HIV) infection has afforded patients longevity while increasing the burden of arthroplasty procedures because of the increased risk of osteonecrosis, fragility fractures, and degenerative joint disease. Early publications on hip and knee arthroplasty in HIV-positive patients reported a high risk of complications, although some more recent publications demonstrated acceptable outcomes. Despite the widespread nature of the HIV pandemic, there is a paucity of literature addressing outcomes following joint arthroplasty in infected patients. We pooled available studies to obtain the best evidence regarding the safety of total hip and knee arthroplasty procedures in HIV-positive patients. The studies identified were heterogeneous, precluding a meta-analysis. However, we performed a review of the literature focusing on complications and outcomes.
METHODS
Twenty-one published English-language articles involving 6,516,186 joints were identified by a systematic review as suitable for inclusion in the study. The articles were analyzed for complication and prosthesis survivorship rates and relative risks.
RESULTS
An overall complication rate of 3.3% was found across the 19 articles that provided such data. HIV-positive patients had a significantly elevated risk of periprosthetic joint infection, at 7.6%, compared with HIV-negative patients, at 3.3% (relative risk = 2.28, 95% confidence interval = 2.14 to 2.43). Eleven articles were suitable for analysis of prosthesis survivorship, and survivorship rates did not differ significantly between HIV-positive and negative patients.
CONCLUSIONS
Total hip and total knee arthroplasty appear to be safe procedures with acceptable outcomes in HIV-positive patients.

Review
PURPOSE
Approximately one-third of the world's population has Toxoplasma gondii infection, and one of the main routes of transmission is organ transplantation. The aim of this study was to evaluate the impact of Toxoplasma infection on liver transplantation patients.
METHODOLOGY
We searched PubMed, Lilacs, Medline, Science direct, Scielo, Ebsco, Springer, Wiley, Ovid and Google Scholar for reports published up to June 2017, and a systematic review was performed.
RESULTS
Twenty cases were analysed before and after liver transplantation. Primary and reactivated infections were investigated. Before transplantation, positive IgG antibodies were the predominant serological markers in donors and recipients: 40 % (D+/R-), 20 % (D+/R+) and 20 % (D-/R+). IgM was present in only 5 % of the donors (D+/R-). In four cases, the serological markers were not specified or were negative (D?/R? or D?/R-). After transplantation, IgM anti-Toxoplasma antibodies were found in 30 % of the recipients, and in 67 % of the seronegative recipients the presence of Toxoplasma DNA or tachyzoites was reported, suggesting a primary infection. Clinical symptoms were meningitis, massive cerebral oedema, encephalitis and seizures. Treatment was administered in 70 % of the patients, and 40 % died after presenting symptoms associated with Toxoplasma infection.
CONCLUSIONS
Although we review Toxoplasma infection and liver transplantation cases, problems associated with the parasite may be greater than identified. Hence, follow-up studies on Toxoplasma infection in liver transplantation patients are recommended.

Review
INTRODUCTION
One-stage exchange is the gold-standard for management of periprosthetic shoulder infection. The present review compares efficacy between 1- and 2-stage exchange in this indication.
MATERIAL AND METHODS
We performed a systematic literature review and meta-analysis following the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) criteria. The literature search used the Medline, Embase and Central data-bases. The studies included assessed 1- and 2-stage exchange in periprosthetic shoulder infection. The main outcome was reinfection rate, and the secondary outcome postoperative complications rate.
RESULTS
Twenty-one studies, for 501 patients, were included: 5 assessing 1-stage exchange, 11 2-stage, and 5 both. Mean follow-up was 4.3 years (range, 2-6.1 years). Mean reinfection rates ranged between 0 and 50% in 1-stage exchange and between 0 and 36.8% in 2-stage exchange. The combined rate was 7% (95% CI, 3.8-12.5%) in 1-stage and 21.3% (95% CI, 16-27.9%) in 2-stage exchange. Mean complications rates ranged between 0 and 50% in 1-stage exchange and between 5.7% and 73%% in 2-stage exchange. The combined rate was 17% (95% CI, 11.9-23.9%) in 1-stage and 32.8% (95% CI, 25.8-40.6%) in 2-stage exchange.
DISCUSSION
To our knowledge, the present meta-analysis is the first to assess results in 1- and 2-stage exchange for chronic periprosthetic shoulder infection.
CONCLUSION
One-stage exchange seemed to provide better results, with less reinfection and fewer complications than 2-stage exchange.

Meta-Analysis Review
BACKGROUND
Elective hysterectomy is commonly performed for benign gynaecological conditions. Hysterectomy can be performed abdominally, laparoscopically, or vaginally, with or without laparoscopic assistance. Antibiotic prophylaxis consists of administration of antibiotics to reduce the rate of postoperative infection, which otherwise affects 40%-50% of women after vaginal hysterectomy, and more than 20% after abdominal hysterectomy. No Cochrane review has systematically assessed evidence on this topic.
OBJECTIVES
To determine the effectiveness and safety of antibiotic prophylaxis in women undergoing elective hysterectomy.
SEARCH METHODS
We searched electronic databases to November 2016 (including the Cochrane Gynaecology and Fertility Group Specialised Register, the Cochrane Central Register of Studies (CRSO), MEDLINE, Embase, PsycINFO, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), as well as clinical trials registers, conference abstracts, and reference lists of relevant articles.
SELECTION CRITERIA
All randomised controlled trials (RCTs) comparing use of antibiotics versus placebo or other antibiotics as prophylaxis in women undergoing elective hysterectomy.
DATA COLLECTION AND ANALYSIS
We used Cochrane standard methodological procedures.
MAIN RESULTS
We included in this review 37 RCTs, which performed 20 comparisons of various antibiotics versus placebo and versus one another (6079 women). The quality of the evidence ranged from very low to moderate. The main limitations of study findings were risk of bias due to poor reporting of methods, imprecision due to small samples and low event rates, and inadequate reporting of adverse effects. Any antibiotic versus placebo Vaginal hysterectomyModerate-quality evidence shows that women who received antibiotic prophylaxis had fewer total postoperative infections (risk ratio (RR) 0.28, 95% confidence interval (CI) 0.19 to 0.40; five RCTs, N = 610; I = 85%), less urinary tract infection (UTI) (RR 0.58, 95% CI 0.43 to 0.77; eight RCTs, N = 1790; I = 44%), fewer pelvic infections (RR 0.28, 95% CI 0.20 to 0.39; 11 RCTs, N = 2010; I = 57%), and fewer postoperative fevers (RR 0.43, 95% CI 0.34 to 0.54; nine RCTs, N = 1879; I = 48%) than women who did not receive such prophylaxis. This suggests that antibiotic prophylaxis reduces the average risk of postoperative infection from about 34% to 7% to 14%. Whether this treatment has led to differences in rates of other serious infection remains unclear (RR 0.20, 95% CI 0.01 to 4.10; one RCT, N = 146; very low-quality evidence).Data were insufficient for comparison of adverse effects. Abdominal hysterectomyWomen who received antibiotic prophylaxis of any class had fewer total postoperative infections (RR 0.16, 95% CI 0.06 to 0.38; one RCT, N = 345; low-quality evidence), abdominal wound infections (RR 0.64, 95% CI 0.45 to 0.92; 11 RCTs, N = 2434; I = 0%; moderate-quality evidence), UTIs (RR 0.39, 95% CI 0.29 to 0.51; 11 RCTs, N = 2547; I = 26%; moderate-quality evidence), pelvic infections (RR 0.50, 95% CI 0.35 to 0.71; 11 RCTs, N = 1883; I = 11%; moderate-quality evidence), and postoperative fevers (RR 0.60, 95% CI 0.51 to 0.70; 11 RCTs, N = 2581; I = 51%; moderate-quality evidence) than women who did not receive prophylaxis, suggesting that antibiotic prophylaxis reduces the average risk of postoperative infection from about 16% to 1% to 6%. Whether this treatment has led to differences in rates of other serious infection remains unclear (RR 0.44, 95% CI 0.12 to 1.69; two RCTs, N = 476; I = 29%; very low-quality evidence).It is unclear whether rates of adverse effects differed between groups (RR 1.80, 95% CI 0.62 to 5.18; two RCTs, N = 430; I = 0%; very low-quality evidence). Head-to-head comparisons between antibiotics Vaginal hysterectomyWe identified four comparisons: cephalosporin versus penicillin (two RCTs, N = 470), cephalosporin versus tetracycline (one RCT, N = 51), antiprotozoal versus lincosamide (one RCT, N = 80), and cephalosporin versus antiprotozoal (one RCT, N = 78). Data show no evidence of differences between groups for any of the primary outcomes, except that fewer cases of total postoperative infection and postoperative fever were reported in women who received cephalosporin than in those who received antiprotozoal.Only one comparison (cephalosporin vs penicillin; two RCTs, N = 451) yielded data on adverse effects and showed no differences between groups. Abdominal hysterectomyWe identified only one comparison: cephalosporin versus penicillin (N = 220). Data show no evidence of differences between groups for any of the primary outcomes. Adverse effects were not reported. Combined antibiotics versus single antibiotics Vaginal hysterectomyWe identified three comparisons: cephalosporin plus antiprotozoal versus cephalosporin (one RCT, N = 78), cephalosporin plus antiprotozoal versus antiprotozoal (one RCT, N = 78), and penicillin plus antiprotozoal versus penicillin (one RCT, N = 230). Data were unavailable for most outcomes, including adverse effects. We found no evidence of differences between groups, except that fewer women receiving cephalosporin with antiprotozoal received a diagnosis of total postoperative infection, UTI, or postoperative fever compared with women receiving antiprotozoal. Abdominal hysterectomyWe identified one comparison (penicillin plus antiprotozoal vs penicillin only; one RCT, N = 230). Whether differences between groups occurred was unclear. Adverse effects were not reported. Comparison of cephalosporins in different regimensSingle small trials addressed dose comparisons and provided no data for most outcomes, including adverse effects. Whether differences between groups occurred was unclear. No trials compared route of administration.The quality of evidence for all head-to-head and dose comparisons was very low owing to very serious imprecision and serious risk of bias related to poor reporting of methods.
AUTHORS' CONCLUSIONS
Antibiotic prophylaxis appears to be effective in preventing postoperative infection in women undergoing elective vaginal or abdominal hysterectomy, regardless of the dose regimen. However, evidence is insufficient to show whether use of prophylactic antibiotics influences rates of adverse effects. Similarly, evidence is insufficient to show which (if any) individual antibiotic, dose regimen, or route of administration is safest and most effective. The most recent studies included in this review were 14 years old at the time of our search. Thus findings from included studies may not reflect current practice in perioperative and postoperative care and may not show locoregional antimicrobial resistance patterns.

Review
PURPOSE
To investigate whether prophylactic antibiotics are beneficial on patients undergoing routine dental implant placement procedures and to investigate which administration regimen is the most effective.
METHODS
The primary outcome was implant failure; the secondary outcome was postoperative infection. In the fixed-effects model, the Mantel-Haenszel method was used to calculate pooled relative risks (RRs) at 95% confidence intervals (CIs). To determine the outcomes, the quality of available evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE).
RESULTS
Prophylactic antibiotics significantly decreased the incidence of implant failure (RR, 0.29; 95% CI, 0.15-0.55; P= 0.0002; I2= 0%) but did not decrease infection. There was no statistically significant difference between single preoperative antibiotics (SPA) and preoperative and postoperative antibiotics (PPA) while treating patients with dental implant failure (RR, 1.07; 95% CI, 0.31-3.62; P= 0.92). No statistically significant difference was observed between SPA and PPA when prescribed to treat infection postoperatively (RR, 1.05; 95% CI, 0.29-3.85; P= 0.94; I2= 0%).
CLINICAL SIGNIFICANCE
The administration of prophylactic antibiotics significantly reduced the failure of dental implants under ordinary conditions. Furthermore, single preoperative antibiotics and preoperative and postoperative antibiotics had similar effects on dental implant failures and infections.

Meta-Analysis Review
The aim of this systematic review and meta-analysis was to investigate whether there are any effects of diabetes mellitus on implant failure rates, postoperative infections, and marginal bone loss. An electronic search without time or language restrictions was undertaken in March 2014. The present review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligibility criteria included clinical human studies. The search strategy resulted in 14 publications. The I (2) statistic was used to express the percentage of total variation across studies due to heterogeneity. The inverse variance method was used for the random effects model when heterogeneity was detected or for the fixed effects model when heterogeneity was not detected. The estimates of an intervention for dichotomous outcomes were expressed in risk ratio and in mean difference in millimeters for continuous outcomes, both with a 95% confidence interval. There was a statistically significant difference (p = .001; mean difference = 0.20, 95% confidence interval = 0.08, 0.31) between diabetic and non-diabetic patients concerning marginal bone loss, favoring non-diabetic patients. A meta-analysis was not possible for postoperative infections. The difference between the patients (diabetic vs. non-diabetic) did not significantly affect implant failure rates (p = .65), with a risk ratio of 1.07 (95% confidence interval = 0.80, 1.44). Studies are lacking that include both patient types, with larger sample sizes, and that report the outcome data separately for each group. The results of the present meta-analysis should be interpreted with caution because of the presence of uncontrolled confounding factors in the included studies.
