Review
Intracranial aneurysms (IAs) are abnormal dilations of the cerebral vessels, which pose a persistent threat of cerebral hemorrhage. Inflammation is known to contribute to IA development. The nuclear factor "kappa-light-chain-enhancer" of activated B-cells (NF-κB) is the major driver of inflammation. It increases the expression of inflammatory markers and matrix metalloproteinases (MMPs), which contribute heavily to the pathogenesis of IAs. NF-κB activation has been linked to IA rupture and resulting subarachnoid hemorrhage. Moreover, NF-κB activation can result in endothelial dysfunction, smooth muscle cell phenotypic switching, and infiltration of inflammatory cells in the arterial wall, which subsequently leads to the initiation and progression of IAs and consequently results in rupture. After a systematic search, abstract screening, and full-text screening, 30 research articles were included in the review. In this systematic review, we summarized the scientific literature reporting findings on NF-κB's role in the pathogenesis of IAs. In conclusion, the activation of the NF-κB pathway was associated with IA formation, progression, and rupture.

Review
Although gastroschisis is often diagnosed by prenatal ultrasound, there is still a gap in the literature about which prenatal ultrasound markers can predict complex gastroschisis. This systematic review and meta-analysis aimed to investigate the ultrasound markers that characterize complex gastroschisis. A systematic review of the literature was conducted according to the guidelines of PRISMA. The protocol was registered (PROSPERO ID CRD42020211685). Meta-analysis was displayed graphically on Forest plots, which estimate prevalence rates and risk ratios, with 95% confidence intervals, using STATA version 15.0. The combined prevalence of intestinal complications in fetuses with complex gastroschisis was 27.0%, with a higher prevalence of atresia (about 48%), followed by necrosis (about 25%). The prevalence of deaths in newborns with complex gastroschisis was 15.0%. The predictive ultrasound markers for complex gastroschisis were intraabdominal bowel dilatation (IABD) (RR 3.01, 95% CI 2.22 to 4.07; I = 15.7%), extra-abdominal bowel dilatation (EABD) (RR 1.55, 95% CI 1.01 to 2.39; I = 77.1%), and polyhydramnios (RR 3.81, 95% CI 2.09 to 6.95; I = 0.0%). This review identified that IABD, EABD, and polyhydramnios were considered predictive ultrasound markers for complex gastroschisis. However, evidence regarding gestational age at the time of diagnosis is needed.

Meta-Analysis
This meta-analysis was performed to compare the efficacy and safety of dilatation and curettage (D&C) (simply D&C or combined with other treatments) and lesion resection for cesarean scar pregnancy (CSP). A search of English and Chinese databases from 2010 to 2019 was conducted. Thirty one studies were retrieved including sixteen random controlled and fifteen case controlled trials. Compared with abdominal resection surgery(ARS) and vaginal resection surgery(VRS), uterine artery embolization(UAE)+D&C has no obvious difference in curative effect and safety (UAE + D&C versus ARS: Cure rate(CR): P = 0.076, time for menstruation recovery/β-HCG normalization: P = 0.545/0.949,Blood loss: P = 0.005, adverse event: P = 0.420; versus VRS: CR: P = 0.085, time for menstruation recovery/β-HCG normalization: P < 0.001/P = 0.031,Blood loss: P = 0.902, adverse event: P = 0.249). UAE + D&C associated with lower blood loss and less postoperative complication than laparoscopic resection surgery(LRS), but LRS take more advantages in terms of the curative effect (CR: P = 0.047, time for menstruation recovery/β-HCG normalization: P = 0.352/0.103). The efficacy and safety of VRS are better than D&C, methotrexate (MTX) + D&C (D&C versus VRS: CR: P < 0.001, time for β-HCG normalization: P = 0.363,blood loss: P < 0.001, adverse event: P = 0.046; MTX + D&C versus VRS: CR: P < 0.001, time for menstruation recovery/β-HCG normalization: P < 0.001/P = 0.005, blood loss: P < 0.001, adverse event: P < 0.001). Lesion resection had advantages in shorter time for menstrual recovery/β-HCG normalization and less adverse events, lower failure rate over the administration of D&C treatments. In detail, the curative effect of UAE + D&C is similar to ARS and VRS, but inferior to LRS, while the safety of UAE + D&C is better than LRS. The efficacy and safety of simply D&C and MTX + D&C are not as good as VRS.

OBJECTIVE
Uterine perforation is a potential, not rare complication of all intrauterine procedures and may be associated with injury of surrounding organs and structures. The incidence, risk factors, possible prevention, dia-gnosis, management and impact on future reproduction is reviewed here.
METHODS
Systematic review of available sources on the topic was carried out using the PubMed database and textbooks of Czech authors.
CONCLUSION
Some risk factors that make access to the uterine cavity difficult may be prevented, however, others remain unpreventable. For patients in whom the perforation occurred during sondage, dilatation or insertion of blunt and cold instrument, without significant bleeding and who are hemodynamically stable, observation is recommended rather than immediate abdominal exploration. The exception are young women planning pregnancy in whom endoscopic suture is indicated. Abdominal exploration is required in patients who have been injured by electrosurgical or sharp device, laser, vacuum curette, who are hemodynamically unstable or show signs of severe bleeding or visceral injury.

The past 20 years witnessed an invigoration of research on labor progression and a change of thinking regarding normal labor. New evidence is emerging, and more advanced statistical methods are applied to labor progression analyses. Given the wide variations in the onset of active labor and the pattern of labor progression, there is an emerging consensus that the definition of abnormal labor may not be related to an idealized or average labor curve. Alternative approaches to guide labor management have been proposed; for example, using an upper limit of a distribution of labor duration to define abnormally slow labor. Nonetheless, the methods of labor assessment are still primitive and subject to error; more objective measures and more advanced instruments are needed to identify the onset of active labor, monitor labor progression, and define when labor duration is associated with maternal/child risk. Cervical dilation alone may be insufficient to define active labor, and incorporating more physical and biochemical measures may improve accuracy of diagnosing active labor onset and progression. Because the association between duration of labor and perinatal outcomes is rather complex and influenced by various underlying and iatrogenic conditions, future research must carefully explore how to integrate statistical cut-points with clinical outcomes to reach a practical definition of labor abnormalities. Finally, research regarding the complex labor process may benefit from new approaches, such as machine learning technologies and artificial intelligence to improve the predictability of successful vaginal delivery with normal perinatal outcomes.

Meta-Analysis Review
OBJECTIVE
This systematic review and meta-analysis aimed to describe the features of right ventricular impairment and pulmonary hypertension in coronavirus disease (COVID-19) and assess their effect on mortality.
DESIGN
The authors carried out a systematic review and meta-analysis of observational studies.
SETTING
The authors performed a search through PubMed, the International Clinical Trials Registry Platform, and the Cochrane Library for studies reporting right ventricular dysfunction in patients with COVID-19 and outcomes.
PARTICIPANTS
The search yielded nine studies in which the appropriate data were available.
INTERVENTIONS
Pooled odds ratios were calculated according to the random-effects model.
MEASUREMENTS AND MAIN RESULTS
Overall, 1,450 patients were analyzed, and half of them were invasively ventilated. Primary outcome was mortality at the longest follow-up available. Mortality was 48.5% versus 24.7% in patients with or without right ventricular impairment (n = 7; OR = 3.10; 95% confidence interval [CI] 1.72-5.58; p = 0.0002), 56.3% versus 30.6% in patients with or without right ventricular dilatation (n = 6; OR = 2.43; 95% CI 1.41-4.18; p = 0.001), and 52.9% versus 14.8% in patients with or without pulmonary hypertension (n = 3; OR = 5.75; 95% CI 2.67-12.38; p < 0.001).
CONCLUSION
Mortality in patients with COVID-19 requiring respiratory support and with a diagnosis of right ventricular dysfunction, dilatation, or pulmonary hypertension is high. Future studies should highlight the mechanisms of right ventricular derangement in COVID-19, and early detection of right ventricular impairment using ultrasound might be important to individualize therapies and improve outcomes.

Meta-Analysis
BACKGROUND
Crohn's disease (CD) is a chronic progressive condition that is complicated by intestinal or colonic stricture in nearly 30% of cases within 10 years of the initial diagnosis. Endoscopic balloon dilation (EBD) is associated with a risk of perforations and recurrence rates of up to 60% at 5 years. Endoscopic stenting has been used as an alternative to EBD, but data on its safety and efficacy are limited. We conducted a systematic review and meta-analysis to assess the outcomes of endoscopic stenting in CD-related strictures.
METHODS
A systematic and detailed search was run in January 2022 with the assistance of a medical librarian for studies reporting on outcomes of endoscopic stenting in CD-related strictures. Meta-analysis was performed using random-effects model, and results were expressed in terms of pooled proportions along with relevant 95% confidence intervals (CIs).
RESULTS
Nine studies with 163 patients were included in the final analysis. Self-expanding metal stents (SEMS) including both partial and fully covered were used in 7 studies, whereas biodegradable stents were used in 2 studies. Pooled rate of clinical success and technical success was 60.9% (95% CI, 51.6-69.5; I2 = 13%) and 93% (95% CI, 87.3-96.3; I2 = 0%), respectively. Repeat stenting was needed in 9.6% of patients (95% CI, 5.3-16.7; I2 = 0%), whereas pooled rate of spontaneous stent migration was 43.9% (95% CI, 11.4-82.7; I2 = 88%). Pooled incidence of overall adverse events, proximal stent migration, perforation, and abdominal pain were 15.7%, 6.4%, 2.7%, and 17.9%, respectively. Mean follow-up period ranged from 3 months to 69 months.
DISCUSSION
Endoscopic stenting in CD-related strictures is a safe technique that can be performed with technical ease, albeit with a limited clinical success. Postprocedure abdominal pain and proximal stent migration are some of the common adverse events reported.

Review
Is a Course of Intermittent Self-dilatation with Topical Corticosteroids Superior at Stabilising Urethral Stricture Disease in Men and Improving Functional Outcomes over a Course of Intermittent Self-dilatation Alone? A Systematic Review and Meta-analysis.
CONTEXT
Intermittent self-dilatation (ISD) is a therapeutic strategy used to stabilise a urethral stricture and postpone or avoid further treatment. Adding corticosteroids to this mode of management might further enhance its outcomes by downregulation of collagen deposition and excessive scar tissue formation.
OBJECTIVE
To explore whether a course of ISD with topical corticosteroids is superior at stabilising urethral stricture disease in men and improving functional outcomes over a course of ISD alone.
EVIDENCE ACQUISITION
This systematic review and meta-analysis was undertaken by the European Association of Urology Urethral Strictures Guideline Panel according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines (CRD42021256744). The primary benefit outcome was successful stabilisation of the urethral stricture. Treatment-related complications were the primary harm outcome.
EVIDENCE SYNTHESIS
In total, 978 records were screened for eligibility, ultimately leading to five included studies, all randomised controlled trials, comprising 250 patients, of whom 124 underwent a course of ISD with corticosteroids and 126 underwent a course of ISD alone, all after direct vision internal urethrotomy (DVIU). Successful stabilisation of the stricture was achieved in 77% and 64% of patients in the group with and without corticosteroids, respectively ( = 0.04). No extra complications related to the addition of corticosteroids to the ISD regimen were reported. The risk of bias of the included studies was generally unclear to high.
CONCLUSIONS
Based on the currently available data, a course of ISD with topical corticosteroids appears to be safe and superior at stabilising a urethral stricture after DVIU in the short term to a course of ISD alone. However, given the unclear to high risk of bias in the included studies, further high-quality studies are needed to fully underpin this.
PATIENT SUMMARY
This study shows that addition of topical corticosteroids to intermittent self-dilatation after direct vision internal urethrotomy can better stabilise the stricture in the short term.

Review
Tracheal stenosis (TS) is an iatrogenic sequela after intubation or tracheostomy that is increasing despite technological improvement and skilled respiratory care in the ICU. According to the studies, the rate of TS varies from 10 to 22%, but only 1-2% of these stenoses are severe and present with inspiratory dyspnea that does not respond to medical management. Bronchoscopy is considered the most appropriate diagnostic test, and laser surgery and tracheobronchial stenting are the most commonly performed procedures for tracheal stenosis. However, alternative treatment options, including cryotherapy for inoperable patients, have yet to be studied widely. As the number of patients requiring ICU admission with mechanical intubation is increasing, it is crucial to acknowledge this complication and consider alternative management options. Here we present a review of the use of cryotherapy for post-intubation tracheal stenosis. Pubmed, Cochrane, and EMBASE databases were inquired for studies performed using the keywords 'airway stricture' OR 'airway obstruction' AND 'post-intubation' OR 'post-extubation' OR 'tracheostomy' AND 'cryotherapy'. After the primary and secondary screening, five studies were included in the analysis. We included 67 patients were included in the analysis, with a mean age of 50.2 (range: 42-55) years. Tracheal stenosis and subglottic stricture were the most common sites of stenosis. Twenty-nine patients were treated with cryotherapy only, while the rest 38 patients had cryotherapy followed by balloon dilation. After the intervention, 48 patients experienced improvement, five experienced no change in the symptoms, 13 patients were asymptomatic before the treatment, and one died. No complication was reported in 65 patients, with only minor complications reported in rest. Although, there is no clear treatment protocol for patients with inoperable tracheal stenosis. Our review demonstrates that cryotherapy for inoperable tracheal stenosis can be an acceptable alternative treatment with significant clinical improvement. Additionally, cryotherapy has fewer adverse effects compared to other treatment options.

Meta-Analysis Review
OBJECTIVES
The primary objective was to perform a systematic review of predictive factors for obstetric anal sphincter injury (OASI) occurrence at first vaginal delivery, with the diagnosis made by ultrasound (US-OASI). The secondary objective was to report on incidence rates of sonographic anal sphincter (AS) trauma, including trauma that was not clinically reported at childbirth, among the studies providing data for our primary objective.
METHODS
We conducted a systematic search of MEDLINE, EMBASE, Web of Science, CINAHL, The Cochrane Library and ClinicalTrials.gov databases. Both observational cohort studies and interventional trials were eligible for inclusion. Study eligibility was assessed independently by two authors. Random-effects meta-analyses were performed to pool effect estimates from studies reporting on similar predictive factors. Summary odds ratio (OR) or mean difference (MD) is reported with 95% CI. Heterogeneity was assessed using the I statistic. Methodological quality was assessed using the Quality in Prognosis Studies tool.
RESULTS
A total of 2805 records were screened and 21 met the inclusion criteria (16 prospective cohort studies, three retrospective cohort studies and two interventional non-randomized trials). Increasing gestational age at delivery (MD, 0.34 (95% CI, 0.04-0.64) weeks), shorter antepartum perineal body length (MD, -0.60 (95% CI, -1.09 to -0.11) cm), labor augmentation (OR, 1.81 (95% CI, 1.21-2.71)), instrumental delivery (OR, 2.13 (95% CI, 1.13-4.01)), in particular forceps extraction (OR, 3.56 (95% CI, 1.31-9.67)), shoulder dystocia (OR, 12.07 (95% CI, 1.06-137.60)), episiotomy use (OR, 1.85 (95% CI, 1.11-3.06)) and shorter episiotomy length (MD, -0.40 (95% CI, -0.75 to -0.05) cm) were associated with US-OASI. When pooling incidence rates, 26% (95% CI, 20-32%) of women who had a first vaginal delivery had US-OASI (20 studies; I = 88%). In studies reporting on both clinical and US-OASI rates, 20% (95% CI, 14-28%) of women had AS trauma on ultrasound that was not reported clinically at childbirth (16 studies; I = 90%). No differences were found in maternal age, body mass index, weight, subpubic arch angle, induction of labor, epidural analgesia, episiotomy angle, duration of first/second/active-second stages of labor, vacuum extraction, neonatal birth weight or head circumference between cases with and those without US-OASI. Antenatal perineal massage and use of an intrapartum pelvic floor muscle dilator did not affect the odds of US-OASI. Most (81%) studies were judged to be at high risk of bias in at least one domain and only four (19%) studies had an overall low risk of bias.
CONCLUSION
Given the ultrasound evidence of structural damage to the AS in 26% of women following a first vaginal delivery, clinicians should have a low threshold of suspicion for the condition. This systematic review identified several predictive factors for this. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.
