OBJECTIVE
The aim of this study was to determine the association between fluoroquinolones (FQs) use, the risk of aortic aneurysm or dissection (AAD), and the prognosis of patients with pre-existing AAD.
MATERIALS AND METHODS
We searched PubMed, EMBASE, CENTRAL, Scopus, and Web of Science on 31 March 2022. Observational studies that evaluated the association of FQs with AAD risk in the general population or FQs with the prognosis of patients with preexisting AAD and presented adjusted effect estimates were included. Two reviewers assessed study eligibility, extracted data, and assessed the risk of bias and certainty of evidence using GRADE.
RESULTS
Of the 13 included studies, 11 focused on the association of FQs with AAD incidence, and only one study investigated the association of FQs with the patient with AAD prognosis. FQ use was associated with an increased risk of AAD within 30 days (RR: 1.42; 95% CI: 1.11-1.81; very low certainty) and 60 days (RR: 1.44; 95% CI: 1.26-1.64; low certainty). Specifically, the association was significant when compared with amoxicillin, azithromycin, doxycycline, or no antibiotic use. Furthermore, patients with preexisting AAD exposure to FQ had an increased risk of all-cause mortality (RR: 1.61; 95% CI: 1.50-1.73; moderate certainty) and aortic-specific mortality (RR: 1.80; 95% CI: 1.50-2.15; moderate certainty), compared to the non-exposed FQ group within a 60-day risk period.
CONCLUSION
FQs were associated with an increased incidence of AAD in the general population and a higher risk of adverse outcomes in patients with preexisting AAD. Nevertheless, the results may be affected by unmeasured confounding factors. This should be considered by physicians contemplating using FQs in patients with aortic dilation and those at high risk of AAD.

Meta-Analysis Review
INTRODUCTION
Chemotherapy and radiation therapy are considered standard treatments for stage II seminoma patients; however, these therapies are associated with long-term toxicities. Recently, retroperitoneal lymph node dissection has emerged as an alternative strategy, and the first three phase II trials were published in 2023 with promising results. The present study conducted a systematic review and meta-analysis to evaluate this surgery as an alternative treatment for stage IIA/B seminoma patients.
PURPOSE
Seminomas are the most common testicular tumors, often affecting young adult males. Standard treatments for stage II seminomas include chemotherapy and radiation therapy, but these therapies are associated with long-term toxicities. Thus, identifying alternative strategies is paramount. Herein, we conducted a systematic review and meta-analysis to appraise the efficacy and safety of retroperitoneal lymph node dissection (RPLND) for treating this condition.
METHODS
We systematically searched the PubMed, Embase, and Cochrane databases for studies evaluating RPLND as a primary treatment for stage II A/B seminomas. Using a random-effects model, single proportion and means and pooled 2-year recurrence-free survival rates with hazard rates and 95% CI were calculated.
RESULTS
Seven studies were included, comprising 331 males with stage II seminomas. In the pooled analysis, the recurrence rate was 17.69% (95% CI 12.31-24.75), and the 2-year RFS rate was 81% (95% CI 0.77-0.86). The complication rate was 9.16% (95% CI 6.16-13.42), the Clavien-Dindo > 2 complication rate was 8.83% (95% CI 5.76-13.31), and the retrograde ejaculation rate was 7.01% (95% CI 3.54-13.40). The median operative time was 174.68 min (95% CI 122.17-249.76 min), median blood loss was 105.91 mL (95% CI 46.89-239.22 mL), and patients with no evidence of lymph node involvement ranged from 0-16%.
CONCLUSIONS
Primary RPLNDs for treating stage IIA/B seminomas have favorable RFS rates, with low complication and recurrence rates. These findings provide evidence that this surgery is a viable alternative therapy for these patients.

Meta-Analysis
BACKGROUND
Neck dissection has a central role in the management of head and neck cancers. This systematic review aimed to compare the intraoperative and postoperative parameters between conventional and LigaSure Small Jaw (LSJ)-assisted neck dissection.
METHODS
PubMed (MEDLINE), Embase, and the Cochrane Library were searched. independently by two authors for relevant articles comparing the outcomes of conventional and LSJ-assisted neck dissection. Data from each study were extracted, and a random-effects model was used in the pooled analysis.
RESULTS
Compared with conventional techniques, LSJ-assisted neck dissection was associated with a significantly reduced operative time. The rates of postoperative hematoma, infection, amount of intraoperative blood loss, the length of hospital stay and the drainage amount showed no significant intergroup differences.
CONCLUSIONS
The meta-analysis provides evidence that properly using LSJ may reduce the operative time compared with that of conventional techniques. Surgeons may consider using LSJ in neck dissection according to personal experiences.

Review
A systematic review and meta-analysis of Harmonic technology compared with conventional techniques in mastectomy and breast-conserving surgery with lymphadenectomy for breast cancer.
BACKGROUND
Mastectomy and breast-conserving surgery (BCS) are important treatment options for breast cancer patients. A previous meta-analysis demonstrated that the risk of certain complications can be reduced with the Harmonic technology compared with conventional methods in mastectomy. However, the meta-analysis did not include studies of BCS patients and focused on a subset of surgical complications. The objective of this study was to compare Harmonic technology and conventional techniques for a range of clinical outcomes and complications in both mastectomy and BCS patients, including axillary lymph node dissection.
METHODS
A comprehensive literature search was performed for randomized controlled trials comparing Harmonic technology and conventional methods in breast cancer surgery. Outcome measures included blood loss, drainage volume, total complications, seroma, necrosis, wound infections, ecchymosis, hematoma, hospital length of stay, and operating time. Risk of bias was analyzed for all studies. Meta-analysis was performed using random-effects models for mean differences of continuous variables and a fixed-effects model for risk ratios of dichotomous variables.
RESULTS
Twelve studies met the inclusion criteria. Across surgery types, compared to conventional techniques, Harmonic technology reduced total complications by 52% (P=0.002), seroma by 46% (P<0.0001), necrosis by 49% (P=0.04), postoperative chest wall drainage by 46% (P=0.0005), blood loss by 38% (P=0.0005), and length of stay by 22% (P=0.007). Although benefits generally appeared greatest in mastectomy patients with lymph node dissection, Harmonic technology showed significant reductions in complications in the BCS study subgroup.
CONCLUSION
In this meta-analysis of both mastectomy and BCS procedures, the use of Harmonic technology reduced the risk of most complications by about half across breast cancer surgery patients. These benefits may be due to superior hemostatic capabilities of Harmonic technology and better dissection, particularly lymph node dissection. Reduction in complications and other resource outcomes may engender lower downstream health care costs.

Meta-Analysis Review
Endoscopic submucosal dissection (ESD) is an advanced endoscopic procedure for management of gastrointestinal tumours. ESD is usually performed under sedation. However, the use of general anaesthesia (GA) has been hypothesised to improve ESD outcomes. We performed a systematic review and meta-analysis to compare GA against sedation in ESD. A systematic literature search was performed on Cochrane Library, EMBASE and MEDLINE using the terms "General Anaesthesia", "Sedation" and "Endoscopic submucosal dissection". Original articles comparing GA versus sedation in ESD were included. The risk of bias and level of evidence were assessed by validated methods. This review is registered in PROSPERO (CRD42021275813). 176 articles were found in the initial literature search, and 7 articles (comprising 518 patients receiving GA and 495 receiving sedation) were included. Compared with sedation, GA was associated with higher en-bloc resection rates in oesophageal ESD (RR 1.05; 95% CI: 1.00-1.10; I 2 = 65%; P = 0.05). GA patients also trended towards lower rates of gastrointestinal perforation in all ESD procedures (RR 0.62; 95% CI: 0.21-1.82; I 2 = 52%; P = 0.06). Rates of intra- procedural desaturation and post-procedural aspiration pneumonia were lower in GA patients than in patients under sedation. The included studies had a moderate to high risk of bias, and the overall level of evidence was low. GA appears safe and feasible for ESD, yet high-quality trials will be required before GA can be regularly implemented for ESD.

Review
The advantages of endoscopic submucosal dissection (ESD) over endoscopic mucosal resection for large colorectal neoplasms are well established; however, the technical challenges and lack of adequate training in ESD limit its widespread adoption in Western countries. A literature search was performed in Medline, Embase, Web of Science, and the Cochrane Library for studies conducted in non-Asian countries evaluating the effectiveness of colorectal ESD. A random effects model was used to obtain pooled en bloc, R0 resection rates, and adverse events (AEs). Thirty-three studies comprising 3,958 ESD procedures met the inclusion criteria. Of the polyps, 96.7% (2,817 of 2913) were ≥ 2 cm. Pooled en bloc resection (31 studies), R0 resection (29 studies), and curative resection rates were 84.6% (95% confidence interval [CI] [83.3%-85.9%]), 75.6% (95% CI [74.1%-77.0%]), and 81.9% (95% CI [78.6%-84.9%]), respectively. Surgery for invasive cancer was performed in 4.8% (23 studies). ESD-related perforation (25 studies) was observed in 5.5% and bleeding in 4.1% (delayed bleeding 3.4%). 1.8% of patients underwent surgery for procedure-related complications. A high degree of heterogeneity was observed for en bloc resection, R0 resection, and curative resection. Heterogeneity for AEs (perforation [I 13%], delayed bleeding [I 30%], and overall bleeding [I 49%]) was low to moderate. The effectiveness of colorectal ESD for large colorectal polyps and early colorectal cancers is improving in Western countries, and recent resection rates are comparable to that seen in Asia. Colorectal perforation is still observed in about 5% of ESD; however, < 2% of patients need emergency surgery for AEs.

Mycetoma is one of the badly neglected tropical diseases, characterised by subcutaneous painless swelling, multiple sinuses, and discharge containing aggregates of the infecting organism known as grains. Risk factors conferring susceptibility to mycetoma include environmental factors and pathogen factors such as virulence and the infecting dose, in addition to host factors such as immunological and genetic predisposition. Epidemiological evidence suggests that host genetic factors may regulate susceptibility to mycetoma and other fungal infections, but they are likely to be complex genetic traits in which multiple genes interact with each other and environmental factors, as well as the pathogen, to cause disease. This paper reviews what is known about genetic predisposition to fungal infections that might be relevant to mycetoma, as well as all studies carried out to explore host genetic susceptibility to mycetoma. Most studies were investigating polymorphisms in candidate genes related to the host immune response. A total of 13 genes had allelic variants found to be associated with mycetoma, and these genes lie in different pathways and systems such as innate and adaptive immune systems, sex hormone biosynthesis, and some genes coding for host enzymes. None of these studies have been replicated. Advances in genomic science and the supporting technology have paved the way for large-scale genome-wide association and next generation sequencing (NGS) studies, underpinning a new strategy to systematically interrogate the genome for variants associated with mycetoma. Dissecting the contribution of host genetic variation to susceptibility to mycetoma will enable the identification of pathways that are potential targets for new treatments for mycetoma and will also enhance the ability to stratify 'at-risk' individuals, allowing the possibility of developing preventive and personalised clinical care strategies in the future.

Review
INTRODUCTION
Total mesorectal excision (TME) is the standard surgical treatment for mid and low rectal cancer. The procedure is performed by open, laparoscopic or robotic approaches. Transanal TME (TaTME) is a new procedure that potentially solves some difficulties in the pelvic part of the dissection. We aimed to evaluate the literature on TaTME.
METHODS
We performed a systematic search of the literature in the PubMed and Embase databases. Both authors assessed the studies. All publications on TaTME were included with the exception of review articles.
RESULTS
A total of 29 studies (336 patients) were included. Only low-quality evidence is available, and the literature consists of case reports and case series. Studies represent the initial experience of surgeons/centres. No precise indication for TaTME is yet specified other than the presence of mid and low rectal tumours, although the potential advantages seem to be related to a bulky mesorectum in the male pelvis. The preliminary results are encouraging and the most serious complication is urethral injury. The oncological results are acceptable, although the follow-up is short.
CONCLUSION
TaTME is a feasible approach for mid and low rectal cancers. Long-term follow-up data are awaited regarding functional results, local recurrence and survival, and to facilitate comparison with standard laparoscopic or robotic rectal resections.

Review
Radical prostatectomy (RP) is one of the recommended treatments to achieve oncological outcomes in localized prostate cancer. However, a radical prostatectomy is a major abdominopelvic surgery. Venous thromboembolism (VTE) is a well-known complication associated with surgical procedures, including RP. There is a lack of consensus regarding VTE prophylaxis in urological procedures. The aim of this systematic review and meta-analysis was to investigate different aspects of VTE in post-radical prostatectomy patients. A comprehensive literature search was performed, and relevant data were extracted. The primary aim was to perform a systematic review and meta-analysis (wherever possible) of VTE occurrence in post-RP patients in relation to surgical approach, pelvic lymph node dissection, and type of prophylaxis (mechanical or combined prophylaxis). The secondary aim was to investigate the incidence and other risk factors of VTE in post-RP patients. A total of 16 studies were included for quantitative analysis. Statistical methods for analysis included the DerSimonian-Laird random effects. We were able to conclude that the overall incidence of VTE in post-radical prostatectomy is 1% (95% CI) and minimally invasive procedures (MIS), including laparoscopic, as well as robotic procedures for radical prostatectomy and RP without pelvic lymph node dissection (PLND), are associated with less risk of developing VTE. Additional pharmacological prophylaxis to mechanical methods may not be necessary in all cases and should be considered in high-risk patients only.

Review
PURPOSE OF REVIEW
Bladder neck preservation (BNP) during radical prostatectomy (RP) has been proposed as a method to improve early recovery of urinary continence after radical prostatectomy. However, there is concern over a possible increase in the risk of positive surgical margins and prostate cancer recurrence rate. A recent systematic review and meta-analysis reported improved early recovery and overall long-term urinary continence without compromising oncologic control. The aim of our study was to perform a critical review of the literature to assess the impact on bladder neck and base margins after bladder neck sparing radical prostatectomy.
EVIDENCE ACQUISITION
We carried out a systematic review of the literature using Pubmed, Scopus and Cochrane library databases in May 2017 using medical subject headings and free-text protocol according to PRISMA guidelines. We used the following search terms: bladder neck preservation, prostate cancer, radical prostatectomy and surgical margins. Studies focusing on positive surgical margins (PSM) in bladder neck sparing RP pertinent to the objective of this review were included.
EVIDENCE SYNTHESIS
Overall, we found 15 relevant studies reporting overall and site-specific positive surgical margins rate after bladder neck sparing radical prostatectomy. This included two RCTs, seven prospective comparative studies, two retrospective comparative studies and four case series. All studies were published between 1993 and 2015 with sample sizes ranging between 50 and 1067. Surgical approaches included open, laparoscopic and robot-assisted radical prostatectomy. The overall and base-specific PSM rates ranged between 7-36% and 0-16.3%, respectively. Mean base PSM was 4.9% in those patients where bladder neck sparing was performed, but only 1.85% in those without sparing. Bladder neck preservation during radical prostatectomy may increase base-positive margins. Further studies are needed to better investigate the impact of this technique on oncological outcomes. A future paradigm could include modification of intended approach to bladder neck dissection when anterior base lesions are identified on pre-operative MRI.
