Meta-Analysis Review
Systematic review and meta-analysis of association of prophylactic cerebrospinal fluid drainage in preventing spinal cord ischemia after thoracic endovascular aortic repair.
OBJECTIVE
We conducted a systemic review and meta-analysis to compare the association between prophylactic cerebrospinal fluid drainage (CSFD) vs non-CSFD in preventing spinal cord ischemia (SCI) after thoracic endovascular aortic repair (TEVAR) for aneurysm and dissection.
METHODS
The MEDLINE, Embase, and Cochrane databases were systematically searched to identify all relevant studies reported before April 1, 2020. A systematic review and meta-analysis were performed. We assessed the association between CSFD strategies, including routine CSFD vs selective CSFD or no CSFD, and the SCI rates after TEVAR for patients with aortic dissection (AD), solitary thoracic aortic aneurysm (TAA), or thoracoabdominal aortic aneurysm (TAAA). Subgroup analyses were conducted to assess the association between different aortic pathologies, including AD and thoracic aneurysms, and SCI rates after TEVAR with and without prophylactic CSFD. The data are presented as the pooled event rates (ERs) and 95% confidence intervals (CIs).
RESULTS
A total of 34 studies of 3561 patients (2671 with TAA or TAAA and 890 with type B AD) were included in the present analysis. The data are presented as the pooled ERs and 95% CIs. The overall SCI rate for patients who had undergone TEVAR with prophylactic CSFD for AD (ER, 1.80%; 95% CI, 0.88%-2.72%) was significantly lower than that for the aortic aneurysm group (ER, 5.73%; 95% CI, 4.20%-7.27%; P < .0001). The SCI rate after TEVAR with prophylactic CSFD was not significantly different from that without CSFD for AD (P = .51). No association was found between the rates of SCI after TEVAR with routine prophylactic CSFD vs selective prophylactic CSFD for aortic aneurysms (P = .76) and AD (P = .70). The SCI rate after TEVAR without CSFD for aortic aneurysms, including isolated TAA and TAAA (ER, 3.49%; 95% CI, 0.23%-6.76%) was not significantly different from that for AD (ER, 3.20%; 95% CI, 0.00%-7.20%; P = .91). For the patients with TAAAs, the rate of SCI after TEVAR with routine prophylactic CSFD was significantly lower than that with selective prophylactic CSFD (P = .04).
CONCLUSIONS
Our systematic review and meta-analysis has shown that SCI occurs more often after TEVAR for aortic aneurysms than for AD. Routine prophylactic CSFD, compared with selective CSFD, was associated with a lower rate of postoperative SCI after TEVAR for TAAAs. No significant association was found between the SCI rate and routine prophylactic CSFD for patients undergoing TEVAR for isolated TAA or AD.

Meta-Analysis Review
BACKGROUND
Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are surgical methods used for rectal neuroendocrine tumors (NETs) with diameters of ≤ 10 mm. However, which method has a higher performance remains uncertain.
OBJECTIVES
Evaluate which of the two methods shows a higher performance.
DESIGN
Systematic review and meta-analysis METHODS: Data from PubMed, Embase, Cochrane Library, and Web of Science were searched from inception to 12 April 2022. Outcomes, including complete resection, en bloc resection, recurrence, perforation, bleeding, and procedure time, were pooled by 95% confidence intervals (95% CI) using a fixed- or random-effects model.
MAIN OUTCOME MEASURES
Complete resection, en bloc resection, and recurrence.
SAMPLE SIZE
18 studies, including 1168 patients were included in the study.
RESULTS
Eighteen retrospective cohort studies were included in this meta-analysis. There were no statistical differences in the rates of complete resection, en bloc resection, recurrence, perforation, and bleeding rates between EMR and ESD. However, a statistical difference was detected in the procedure time; EMR had a significantly shorter time (MD=-17.47, 95% CI=-22.31 - -12.62, <.00001).
CONCLUSIONS
EMR and ESD had similar efficacies and safety profiles in resectioning rectal NETs ≤ 10 mm. Even so, the advantages of EMR included a shorter operation time and expenditure. Thus, with respect to health economics, EMR outperformed ESD.
LIMITATION
Most of these studies are retrospective cohort studies instead of RCTs.
CONFLICT OF INTEREST
None.

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
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
PURPOSE
The development of risk prediction models for breast cancer lymphedema is increasing, but few studies focus on the quality of the model and its application. Therefore, this study aimed to systematically review and critically evaluate prediction models developed to predict breast cancer-related lymphedema.
METHODS
PubMed, Web of Science, Embase, MEDLINE, CNKI, Wang Fang DATA, Vip Database, and SinoMed were searched for studies published from 1 January 2000 to 1 June 2021. And it will be re-run before the final analysis. Two independent investigators will undertake the literature search and screening, and discrepancies will be resolved by another investigator. The Prediction model Risk Of Bias Assessment Tool will be used to assess the prediction models' risk of bias and applicability.
RESULTS
Seventeen studies were included in the systematic review, including 7 counties, of which 6 were prospective studies, only 7 models were validation studies, and 4 models were externally validated. The area under the curve of 17 models was 0.680~0.908. All studies had a high risk of bias, primarily due to the participants, outcome, and analysis. The most common predictors included body mass index, radiotherapy, chemotherapy, and axillary lymph node dissection.
CONCLUSIONS
The predictive factors' strength, external validation, and clinical application of the breast cancer lymphedema risk prediction model still need further research. Healthcare workers should choose prediction models in clinical practice judiciously.

Review
BACKGROUND
Aberrant subclavian artery (AScA) with or without associated Kommerell's diverticulum (KD) is the most frequently encountered anomaly of the aortic arch, it may be life threatening, especially when associated with aneurysmal degeneration. The best management is still debated and depends on many clinical and anatomical factors. A systematic review was conducted to assess the current evidence on the treatment options and their efficacy and safety for AscA and KD repairs.
METHODS
A literature search in PubMed and Cochrane Library was performed, and articles that were published from January 1947 to August 2021 reporting on AscA and KD management were identified. Multicenter studies, single-center series, and case series with three or more patients were considered eligible in the present review. A comparison of outcomes of patients who underwent open surgery (OS), a hybrid approach (HA), and total endovascular repair (ER) (ie, 30-day mortality and stroke were analyzed when available and compared among the three groups (P < .05; Benjamini and Hochberg-adjusted P < .05; Bonferroni-adjusted P < .05). Titles, abstracts, and full texts were evaluated by two authors independently. Primary outcomes included survival rate, perioperative stroke, arm ischemia, and spinal cord ischemia. Endoleak, in the case of HA and ER, and reintervention rates were considered outcomes.
RESULTS
Three hundred thirty-one articles were initially evaluated and 30 studies, totaling 426 patients treated for AScA with 324 KD, were included. Of the 426 patients, 241 were male (56.5%), and the mean patient age was 57.9 ± 12.0 years. The approach was OS in 228 patients, HA in 147 patients, and ER in 51. Dysphagia was the most common presentation in 133 cases. Aortic rupture was observed in 16 of the 426 patients (3.8%), including 14 AScA/KD (3.3%) aneurysm rupture. KD maximum diameter varied widely from 12.6 to 63.6 mm. The overall 30-day mortality was 20 (4.7%) (OS group 8/228 [3.5%]; HA group 10/147 [6.8%]; ER 2/51 [3.9%]; P = NS). The overall stroke rate was 4.9% (21/426) (OS group 10/228 [4.4%]; HA group 6/147 [4.1%]; ER group 5/51 [9.8%]; P = NS), including nine transient and nondisabling neurological deficits. Overall secondary procedures for complications were reported in 36 of the 426 cases (8.4%), mostly owing to endoleak. Follow-up varied from 13 to 74 months.
CONCLUSIONS
This systematic review assessed the current outcomes of the three types of therapeutic management for AScA and KD and demonstrated that they are all relatively safe and effective, providing satisfactory early and midterm outcomes. Long-term outcomes are warranted, especially for total ERs since the long-term durability of stent grafts remains unknown.

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
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.

OBJECTIVE
The management of cervical artery dissections (CADs) is poorly standardized given the scarce number of prospective studies comparing medical and interventional approach to CAD. The aim of the present study is to perform a systematic review and meta-analysis of studies on the treatments of CAD.
METHODS
Systematic review and meta-analysis (pre-registered on PROSPERO [CRD42022297512] are performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses [PRISMA] guidelines searching in three different databases [PubMed, Embase and Cochrane Database]) of studies on medical or interventional approach to CAD. Only prospective studies were selected to reduce the risk of bias for the primary meta-analysis. Secondarily, retrospective studies were also included. The aim was to assess the rate of stroke and of stroke/death/bleeding (major or intracranial) by Der Simonian-Laird weights of random effects model.
RESULTS
After screening 456 articles, 6 prospective and 22 retrospective studies were identified. Two randomized controlled trials and five retrospective studies comparing antiplatelet (APT) vs oral anticoagulant therapy (OAC) for CAD were identified, as well as four prospective and 17 retrospective single-arm studies evaluating stenting for CAD. In the meta-analysis of randomized controlled trials comparing APT vs OAC, 444 patients were considered, and a borderline significant association was identified in terms of stroke/death in the APT vs OAC groups (odds ratio [OR], 5.6; 95% confidence interval [CI], 0.94-33.38; P = .06; I = 0%). No differences were found for the stroke/death/bleeding outcome (OR, 1.25; 95% CI, 0.19-8.18; P = .81; I = 0%) between the two treatments. In the meta-analysis including also retrospective studies, overall risk of bias was considered "serious," and 4104 patients were included with no differences in APT vs OAC for stroke (OR, 1.06; 95% CI, 0.53-2.11; P = .29; I = 18%); no other comparisons were possible. The pooled meta-analysis of prospective studies on stenting for CAD included four series, for a total of 68 patients, in whom stenting was adopted primarily after failed medical therapy or after traumatic dissection. The pooled rate of stroke/death was 7% (95% CI, 3%-17%; I = 0%). The analysis of moderators identified a significant inverse association between the percentage of traumatic dissection and a reduction in postoperative stroke (Y = -1.60-2.02X; P = .03). The pooled rate of the composite endpoint of stroke/death/ or major bleeding was 8% (95% CI, 3%-18%; I = 0%). Secondarily, the meta-analysis also included 17 retrospective studies with overall 457 patients and showed a 2.1% pooled rate of stroke/death (95% CI, 1.0%-3.3%; I = 0%) and 3.2% stroke/death/bleeding (95% CI, 1.8%-4.7%; I = 0%).
CONCLUSIONS
Few prospective studies on CAD treatment are present in literature. APT and OAC seem to have similar efficacy in reducing the recurrence of stroke after CAD. No definitive conclusion can be drawn for stenting, due to the low number of studies available. More prospective studies are necessary to evaluate its potential additional value over medical therapy alone in the early phase after CAD.
