Meta-Analysis Review
Prostate cancer (PC) is the second most incident cancer and the sixth cause of death by cancer in men worldwide. Despite extensive research efforts, no modifiable risk factors have been consistently identified for PC risk. A number of studies have focused on possible relationships between sexually transmitted infections (STIs) and PC. We performed a meta-analysis to explore the association between infection caused by Neisseria gonorrheae, Treponema pallidum, Chlamydia trachomatis, Trichomonas vaginalis, Ureaplasma urealyticum, Mycoplasma hominis, Herpes Simplex Virus types 1 and 2, Human Herpes Virus 8 and Cytomegalovirus, and PC. We conducted a comprehensive, systematic bibliographic search of medical literature to identify relevant studies. We calculated summary relative risk (SRR) and 95% confidence intervals (CI) for the association between each STI and PC through random effect models. Subgroup, meta-regression and sensitivity analyses were carried out to detect between-study heterogeneity and bias. We included 47 studies published between 1971 and 2011. Men who reported having ever had any STI in lifetime had an increased PC (SRR 1.49, 95% CI 1.19-1.92). We found a significantly increased PC risk in men having had gonorrhoea (SRR 1.20, 95% CI 1.05-1.37). No other single STI was significantly associated with PC. Due to high incidence of both STIs and PC worldwide, prevention of STIs may help preventing a considerable number of PC cases.

Review
Male genital schistosomiasis (MGS) may result in eggs lodged in the prostate causing persistent inflammation that may play a major role in prostate carcinogenesis. Globally, prostate cancer (PCa) is one of the most common cancers and the global distribution of PCa overlaps with that of schistosomiasis infections, suggesting a probable causal relationship. Objectives of this review were to assess evidence of co-existence of schistosomiasis and PCa and possible causal association between the two diseases. Relevant literature published between 1950 and 2019 yielded 20 publications on schistosomiasis and PCa co-existence. Schistosoma (S.) haematobium and S. mansoni were associated with MGS manifestation and mostly prostate adenocarcinoma diagnosis. Effects of prostatic MGS infection progressed over time with high Schistosoma egg burden thought to contribute to the development of PCa. Causal association and mechanistic pathways of MGS on PCa development and the role of Schistosoma eggs on the development of PCa remains unestablished.

Review
AIM
To present a summary of the updated guidelines of the Italian Prostate Biopsies Group following the best recent evidence of the literature.
MATERIALS AND METHODS
A systematic review of the new data emerging from 2012-2015 was performed by a panel of 14 selected Italian experts in urology, pathology and radiology. The experts collected articles published in the English-language literature by performing a search using Medline, EMBASE and the Cochrane Library database. The articles were evaluated using a systematic weighting and grading of the level of the evidence according to the Grading of Recommendations Assessment, Development and Evaluation framework system.
RESULTS
An initial prostate biopsy is strongly recommended when i) prostate specific antigen (PSA) >10 ng/ml, ii) digital rectal examination is abnormal, iii) multiparametric magnetic resonance imaging (mpMRI) has a Prostate Imaging Reporting and Data System (PIRADS) ≥4, even if it is not recommended. The use of mpMRI is strongly recommended only in patients with previous negative biopsy. At least 12 cores should be taken in each patient plus targeted (fusion or cognitive) biopsies of suspicious area (at mpMRI or transrectal ultrasound). Saturation biopsies are optional in all settings. The optimal strategy for reducing infection complications is still a controversial topic and the instruments to reduce them are actually weak. The adoption of Gleason grade groups in adjunction to the Gleason score when reporting prostate biopsy results is advisable.
CONCLUSION
These updated guidelines and recommendations are intended to assist physicians and patients in the decision-making regarding when and how to perform a prostatic biopsy.

Meta-Analysis
BACKGROUND
Periodontal disease is a chronic infectious disease caused by bacterial infection which may lead to various systematic diseases. Recently, increasing studies have explored the correlation of periodontal disease with the risk of prostate cancer. However, the findings were inconsistent. Hence, this study aims to investigate the association between periodontal disease and the risk of prostate cancer by a meta-analysis.
MATERIAL AND METHODS
PubMed, EMBASE, and Cochrane were searched for publications up to July 17, 2020. Cohort and case-control studies evaluating the risk of prostate cancer in patients with periodontal disease were included. A fixed or random-effect model was used to calculate the summary relative risk (RR) along with 95% confidence interval (CI). All analyses were conducted using Stata 12.0 software.
RESULTS
Seven studies were included in the final analysis. The pooled estimates showed that periodontal disease was significantly associated with the risk of prostate cancer (RR = 1.17; 95% CI = 1.07-1.27; P = 0.001). Findings of sensitivity analyses proved that the overall results were robust.
CONCLUSIONS
Periodontal disease may be considered as a potential risk factor for prostate cancer. Although it's a possibility, males should be more aware of their oral health and implement effective measures to prevent and treat periodontal disease.

Review
A systematic review to identify risk factors for prostate biopsy-related infection, preventative strategies, and optimal management of infectious complications was conducted. Significant risk factors for postbiopsy infection include urogenital infection, antibiotic use, international travel, hospital exposure, bacteriuria, previous transrectal biopsy, and resistance of fecal flora to antibiotic prophylaxis (especially fluoroquinolones). Patients at risk may benefit from an adjusted biopsy protocol comprising transrectal biopsy under targeted prophylaxis, and/or the use of rectal disinfection techniques or using a transperineal approach. Management of biopsy-related infection should be based on individual risk and local resistance profiles with input from multiple specialties.

Review
INTRODUCTION
Transrectal ultrasound-guided biopsies (TRUS-gb) are associated with both mild and serious complications. Prophylactic antibiotics reduce the risk of septicaemia and mortality; however, no international consensus exists on the timing and duration of antibiotics, including the optimal drug strategy. We reviewed the current evidence supporting use of prophylactic antibiotics and the risk of complications following prostate biopsies.
METHODS
This review was drafted in accordance with the Prisma Guidelines. The PubMed, Embase and Cochrane databases were searched.
RESULTS
A total of 19 eligible trials were identified. One trial demonstrated a significant reduction in the risk of infection after biopsy and reported that oral ciprofloxacin as either a single-dose or a three-day regimen was superior to oral chloramphenicol and norfloxacin. Of three studies investigating the timing of the first dose of antibiotic, one study found that administration 24 h before biopsy versus administration immediately before reduced the relative risk of post-biopsy infection by 55%. Seven studies compared different durations of antibiotic prophylaxis. None showed any benefit from continuing prophylaxis beyond a single dose or a one-day regimen.
CONCLUSION
Evidence supporting a specific antibiotic regimen for TRUS-gb prophylaxis is scarce. Widespread use of fluoroquinolone prophylaxis may be associated with an increase in resistant Escherichia coli strains, posing a potentially major health issue in the future. .

Review
INTRODUCTION
Focal therapy (FT) is a promising alternative with curative intent for Low- to Intermediate-risk localized Prostate Cancer (PCa), claiming better functional outcomes and safety profile than standard whole-gland treatments. Ten different FT modalities have been described in the literature. The objective of our narrative review is to evaluate the safety profile and functional outcomes of these different modalities and the current most used tools of assessment for those outcomes.
MATERIAL AND METHODS
Literature search was performed on 21st February 2023 using PubMed, EMBASE, and Scopus, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA). Articles reporting whole-gland treatments were excluded. All articles reporting functional outcomes were included.
RESULTS
One-hundred-seven studies, reporting data on 6933 patients, were included (26 on High Intensity Focal Ultrasound, 22 on Focal Cryotherapy, 14 on Irreversible Electroporation, 11 on Focal brachytherapy, 10 on Focal Laser Ablation, 8 on Photodynamic Therapy, 3 on Microwave ablation, 3 on Robotic Partial Prostatectomy, 2 on bipolar Radio Frequency Ablation, 1 on Prostatic Artery Embolization, and 7 studies comparing different FTs). Post-operative pad-free rate ranged between 92.3-100%. Greater heterogeneity exists considering the Change in Erectile Function, with Changing in Erectile function- rates ranging between 0-94.4% (Cryotherapy). The most used Patient-Reported Outcome Measures (PROMs) were the International Prostate Symptom Score and the International Index of Erectile Function for incontinence/urinary function and potency, respectively. The most common reported complications were hematuria, infections, and urethral strictures, with rates widely ranging among different treatments. The Clavien-Dindo Classification was the most used (40/88 papers) to describe adverse events.
CONCLUSION
FT is a promising treatment for localized PCa, achieving excellent results in terms of safety and functional outcomes. There is a wide heterogeneity in the definition of PROMS and time of collection between studies. High quality comparative studies with standard treatments are needed to reinforce these findings.

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.

Review
OBJECTIVE
Neisseria gonorrhoeae (Ng) is the second most common sexually transmitted bacterial infection (STI), leading to serious health problems in men, women and newborns. While early antibiotic treatment is effective, infections are increasingly antibiotic-resistant. No systematic reviews present health problems associated with Ng infections or their likelihood of occurrence. The objective, therefore, was to conduct a systematic literature review to address these gaps.
METHODS
A systematic literature review was conducted of all studies with an English abstract published since 1950 (Pubmed)/1966 (Embase). The search included patients with a history of/current sexually transmitted Ng infection. Expected outcomes were defined from published reviews of gonorrhoea health problems. Observational studies with a control group were included. A decision tree determined the best quality studies for each outcome, prioritising generalisable populations, laboratory-confirmed diagnosis, clearly defined outcomes, no STI co-infections, adjusted analyses and risk estimates. Where feasible, a meta-analysis was performed; otherwise, the best quality study estimates were identified.
FINDINGS
In total, 46 studies were included, and 22 health problems were identified. Of these problems, Ng infection was statistically significantly associated with preterm premature ruptures of membranes, preterm birth, low birth weight, stillbirth, infant death, neonatal ophthalmia, schizophrenia in offspring, pelvic inflammatory disease and subsequent tubal infertility, human immunodeficiency virus and prostate cancer/problems. High-quality evidence was generally lacking, with high heterogeneity across studies, and limited or inconclusive data on other health problems.
CONCLUSION
Ng infection is associated with severe health problems in women, men and newborns. More high-quality comparative studies are needed to address the limitations in current knowledge.

Meta-Analysis
There is growing evidence showing a putative association between high-risk human papillomavirus (HR-HPV) infection and an increased risk of PCa. The aim of the current meta-analysis was to evaluate the association between HPV infection and PCa risk. This analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. We included all studies on HPV DNA or antibodies detected in biopsy tissues or sera. Available data were extracted from the article, including means and standard deviations in all case-control groups. Thirty studies that investigated the link between HPV-16 and -18 were identified as eligible for this systematic review and meta-analysis, including a total of 6321 participants. The pooled OR showed increased risk of PCa (OR =1.37; < .01) in men positive for HPV-16. There were seven studies with 2391 PCa cases and 4059 controls investigating the association between HPV-18 infection and PCa risk. Significant heterogeneity between study was found in the pooled analyzes. The pooled OR did not show increased risk of PCa (OR =0.80; = .49) in men positive for HPV-18. This meta-analysis suggests that HPV-16 infection could represent a risk factor for PCa, whereas we found no such association for HPV-18. Further well-conducted studies could be useful to confirm this conclusion.
