Meta-Analysis
OBJECTIVE
To perform a systematic review and meta-analysis of all population-based studies reporting on incidence of acute aortic dissections (AADs).
METHODS
We searched the MEDLINE, EMBASE, CENTRAL, and Open Grey databases from inception to August 2020 for population-based studies reporting on the incidence of AAD. A systematic review was conducted following the PRISMA guidelines using a registered protocol (CRD42020204007). Data were pooled using a random effects model of proportions using Freeman-Tukey double arcsine transformation. The main outcome was the incidence of AAD. Secondary outcomes were incidence type A aortic dissections (TAAD) and type B aortic dissections (TBAD), the incidence of aortic dissection repair and medical management, and the incidence of in-hospital mortality. In addition, we estimated the proportion of aortic dissection repair and mortality (in hospital, overall and specific mortality according to subtype) among patients with AAD.
RESULTS
Thirty-three studies were included. The pooled incidence of AADs was 4.8 per 100,000 individuals/year (95% confidence interval [CI], 3.6-6.1). The incidence of TAAD was 3.0 per 100,000/year (95% CI, 1.8-4.4) and the incidence of TBAD was 1.6 per 100,000/year (95% CI, 1.1-2.2). The incidence of AAD needing repair was 1.4 per 100,000/year (95% CI, 1.0-2.0) (or 1.4 [95% CI, 1.2-1.7] for TAAD and 0.4 [95% CI, 0.2-0.7] for TBAD). The incidence of medically managed AAD was 3.4 per 100,000/year (95% CI, 2.4-4.5). The incidence of in-hospital death owing to AAD was 1.3 per 100,000 individuals/year (95% CI, 0.9-1.9), 1.0 (95% CI, 0.6-1.4; I = 97%) for TAAD, and 0.3 for TBAD (95% CI, 0.2-0.4; I = 96%).
CONCLUSIONS
A global estimate regarding the incidence rate of AADs was achieved. The incidence of AAD varied significantly between study designs and geographical regions. More accurate information on AAD epidemiology is crucial for public health decisions, clinical understanding, and healthcare management.

BACKGROUND
Case reports and case control studies have suggested an association between chiropractic neck manipulation and cervical artery dissection (CAD), but a causal relationship has not been established. We evaluated the evidence related to this topic by performing a systematic review and meta-analysis of published data on chiropractic manipulation and CAD.
METHODS
Search terms were entered into standard search engines in a systematic fashion. The articles were reviewed by study authors, graded independently for class of evidence, and combined in a meta-analysis. The total body of evidence was evaluated according to GRADE criteria.
RESULTS
Our search yielded 253 articles. We identified two class II and four class III studies. There were no discrepancies among article ratings (i.e., kappa=1). The meta-analysis revealed a small association between chiropractic care and dissection (OR 1.74, 95% CI 1.26-2.41). The quality of the body of evidence according to GRADE criteria was "very low."
CONCLUSIONS
The quality of the published literature on the relationship between chiropractic manipulation and CAD is very low. Our analysis shows a small association between chiropractic neck manipulation and cervical artery dissection. This relationship may be explained by the high risk of bias and confounding in the available studies, and in particular by the known association of neck pain with CAD and with chiropractic manipulation. There is no convincing evidence to support a causal link between chiropractic manipulation and CAD. Belief in a causal link may have significant negative consequences such as numerous episodes of litigation.

BACKGROUND
Esophagogastric junction adenocarcinomas (EGJAs) include esophageal and gastric cardia adenocarcinomas (GCAs). These tumors are currently regarded as a single entity, with similar surgical and oncological therapies, although they originate from different organs. Endoscopy allows an early-stage diagnosis, where both subtypes can be differentiated. With this review we aimed to describe the outcomes of endoscopic submucosal dissection for the treatment of esophageal adenocarcinomas (EAs) and GCAs.
METHODS
We identified studies by screening PubMed, Embase and Web of Science. We included all 19 studies that mentioned at least one of the following criteria of interest: ; R0 resection; local recurrences; and/or overall survival.
RESULTS
We found an resection rate superior to 90% for both tumors. R0 resections rates were over 60% for most EAs, vs. 83% for most GCAs. We recorded less than 13% and 20% early and late adverse events for EA, and 10% and 7% for GCA. The local recurrence rate was 8% for EA and 3% for GCA. The overall survival was over 90%.
CONCLUSIONS
Endoscopic submucosal dissection is safe and effective for esophageal and GCAs. These data support the extension of the use of endoscopic submucosal dissection to all EGJAs, including early EAs.

Meta-Analysis Review
BACKGROUND AND PURPOSE
Cervical artery dissection (CAD) involving the carotid or vertebral arteries is an important cause of stroke in younger patients. The purpose of this systematic review is to assess the risk of recurrent CAD.
METHODS
A systematic review and meta-analysis was conducted on studies in which patients experienced radiographically confirmed dissections involving an extracranial segment of the carotid or vertebral artery and in whom CAD recurrence rates were reported.
RESULTS
Data were extracted from 29 eligible studies (n = 5898 patients). Analysis of outcomes was performed by pooling incidence rates with random effects models weighting by inverse of variance. The incidence of recurrent CAD was 4% overall (95% confidence interval (CI) = 3-7%), 2% at 1 month (95% CI = 1-5%), and 7% at 1 year in studies with sufficient follow-up (95% CI = 4-13%). The incidence of recurrence associated with ischemic events was 2% (95% CI = 1-3%).
CONCLUSIONS
We found low rates of recurrent CAD and even lower rates of recurrence associated with ischemia. Further patient-level data and clinical subgroup analyses would improve the ability to provide patient-level risk stratification.

Meta-Analysis
OBJECTIVES
Non-A non-B aortic dissections are rare, and little is known about their natural history, indications for surgery and operative results. We aim to examine the literature to summarize what is known of the natural history of non-A non-B dissections and evaluate the outcomes of the therapeutic options available.
METHODS
An extensive literature search was performed using MEDLINE to find all published studies that report data on the natural history and outcomes of patients with non-A non-B aortic dissection. Data on patients treated with medical therapy were extracted to characterize the natural history. Primary end points included 30-day mortality, stroke and retrograde type A dissection.
RESULTS
Of the 423 studies found, 14 articles (433 patients) fulfilled the inclusion criteria for quantitative analysis. The proportion of medically treated patients ranged from 5 to 54% with a pooled rate of 36% (50/138). The 30-day mortality of patients treated with medical therapy was 14% (7/50). The overall estimated proportion of 30-day mortality for patients who underwent intervention was 3.6% [95% confidence interval (CI) 1.7-5.6%], retrograde type A dissection was 2.6% (95% CI 0.8-4.4%) and stroke was 2.8% (95% CI 1.0-4.5%).
CONCLUSIONS
Despite the likelihood of reporting and selection bias, patients with non-A non-B dissection often have a complicated course requiring some form of intervention. The 30-day mortality of patients treated with medical therapy seems higher than surgical or endovascular therapy. Ideally, further large prospective studies are necessary to confirm our suggestion that early intervention may be indicated in non-A non-B dissections.

Meta-Analysis Review
To perform a meta-analysis and examine the use of D-dimer levels for diagnosing acute aortic dissection (AAD). Medline, Cochrane, EMBASE, and Google Scholar were searched until April 23, 2014, using the following search terms: biomarker, acute aortic dissection, diagnosis, and D-dimer. Inclusion criteria were diagnosis of acute aortic dissection, D-dimer levels obtained, 2-armed study. Outcome measures were the accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of D-dimer level for the diagnosis of AAD. Sensitivity analysis was performed using the leave-one-out approach. Of 34 articles identified, 5 met the inclusion criteria and were included in the analysis. The age of participants was similar between treatments within studies. The number of AAD patients ranged from 16 to 107 (total = 274), and the number of control group patients ranged from 32 to 206 (total = 469). The pooled sensitivity of D-dimer levels in AAD patients was 94.5% (95% confidence interval [CI] 78.1%-98.8%, P < 0.001), and the specificity was 69.1% (95% CI 43.7%-86.5%, P = 0.136). The pooled area under the receiver-operating characteristic curve for D-dimer levels in AAD patients was 0.916 (95% CI 0.863-0.970, P < 0.001). The direction and magnitude of the combined estimates did not change markedly with the exclusion of individual studies, indicating the meta-analysis had good reliability. D-dimer levels are best used for ruling out AAD in patients with low likelihood of the disease.

Intramyocardial dissection (IMD) with ventricular septal rupture (VSR) following myocardial infarction (MI) is a rare subacute form of cardiac rupture. The evidence available in this regard is scarce. We aimed to share our experience and conduct a systematic review of previous cases. We searched the literature and performed a systematic review of previous cases. A total of 37 cases of IMD with VSR were included (1 our original and 36 literature cases). Mean age was 68 ± 8 years and 20 (54.1%) patients were male. Anterior and inferior MI were observed in 14 (37.8%) and 23 (62.2%) cases, respectively. The dissected area was the septum, RV, both septum and RV, or LV apex in 21 (56.8%), 9 (24.3%), 5 (13.5%), and 2 (5.4%), respectively. Apicoseptal and inferoseptal VSR were observed in 15 (40.5%) and 22 (59.5%) cases, respectively. At least one occluded artery was observed in 29 (90.6%) of cases. Reperfusion therapy was done for 15 (40.5%) cases before the VSR occurred. Surgery, percutaneous, and medical therapy were done for 26 (70.3%), 3 (8.1%), and 7 (18.9%) cases, respectively. The mortality rate was significantly higher in the medical versus surgical-treated group (85.7% versus 42.3%, P = .027). There was a trend to higher mortality in the group with dissection of both septum and RV (P = .15). We concluded that echocardiography has a critical role in diagnosing this complication. Surgery is mandatory in IMD with VSR.

Meta-Analysis
OBJECTIVE
To present the pooled quantitative evidence of basic profiles, initial treatment strategies, and clinical outcomes in patients with isolated abdominal aortic dissection (IAAD).
METHODS
A comprehensive systematic review and meta-analysis was performed of all available studies reporting IAAD, retrieved from the MEDLINE, Embase, and Cochrane Databases. The logistic normal random effect model was fitted using the generalised linear mixed model with random intercepts to calculate the pooled proportion estimates.
RESULTS
Seventeen studies with 482 patients were included in this meta-analysis. Male smokers with hyperlipidaemia and hypertension were the most prominent basic profile. IAADs were predominantly spontaneous and infrarenal, and roughly half were acute and symptomatic. Approximately 67% [95% confidence interval (CI) 42-86%] of patients were managed initially conservatively. In the overall population, the 30 day all cause mortality was 3% (95% CI 1-5%) and the long term mortality during follow up was 8% (95% CI 5-14%). Re-intervention during follow up occurred in 8% (95% CI 5-15%) of patients. In the subgroup analysis, patients with conservative treatment had a 30 day mortality of 1% (95% CI 0-8%), a long term mortality of 5% (95% CI 1-29%), and a re-intervention rate of 18% (95% CI 10-29%). Patients with open surgery had a 30 day mortality of 9% (95% CI 0-82%), a long term mortality of 12% (95% CI 4-31%), and a re-intervention rate of 9% (95% CI 1-44%). Patients with endovascular repair had a 30 day mortality of 2% (95% CI 0-10%), a long term mortality of 5% (95% CI 2-13%), a re-intervention rate of 6% (95% CI 3-13%), and a persistent endoleak rate of 4% (95% CI 2-10%).
CONCLUSION
Appropriate initial treatment strategies can be used to obtain acceptable clinical outcomes in patients with IAAD. Invasive intervention is necessary if patients match certain indications for intervention. Regular imaging surveillance should be provided for all patients, especially those treated conservatively.

Meta-Analysis
BACKGROUND
Primary cadaveric studies were reviewed to give a contemporary overview of what is known about innervation of the female breast and nipple/nipple-areola complex.
METHODS
The authors performed a Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant systematic review and meta-analysis. The authors searched four electronic databases for studies investigating which nerve branches supply the female breast and nipple/nipple-areola complex or describing the trajectory and other anatomical features of these nerves. Inclusion criteria for meta-analysis were at least five studies of known sample size and with numerical observed values. Pooled prevalence estimates of nerve branches supplying the nipple/nipple-areola complex were calculated using random-effects meta-analyses; the remaining results were structured using qualitative synthesis. Risk of bias within individual studies was assessed with the Anatomical Quality Assurance checklist.
RESULTS
Of 3653 studies identified, 19 were eligible for qualitative synthesis and seven for meta-analysis. The breast skin is innervated by anterior cutaneous branches and lateral cutaneous branches of the second through sixth and the nipple/nipple-areola complex primarily by anterior cutaneous branches and lateral cutaneous branches of the third through fifth intercostal nerves. The anterior cutaneous branch and lateral cutaneous branch of the fourth intercostal nerve supply the largest surface area of the breast skin and nipple/nipple-areola complex. The lateral cutaneous branch of the fourth intercostal nerve is the most consistent contributory nerve to the nipple/nipple-areola complex (pooled prevalence, 89.0 percent; 95 percent CI, 0.80 to 0.94).
CONCLUSIONS
The anterior cutaneous branch and lateral cutaneous branch of the fourth intercostal nerve are the most important nerves to spare or repair during reconstructive and cosmetic breast surgery. Future studies are required to elicit the course of dominant nerves through the breast tissue.

Review
Despite guideline recommendations, strategies for implementing cardiac rehabilitation (CR) in patients with acute aortic dissection (AAD) are not well established with little evidence to risk stratify prudent and effective guidelines for the many required variables. We conducted a systematic review of studies (2004-2023) reporting CR following type A (TA) and type B (TB) AAD. Our review is limited to open surgical repair for TA and medical treatment for TB. A total of 5 studies were included (4 TA-AAD and 1 TB-AAD) in the qualitative analysis. In general, observational data included 311 patients who had an overall favorable effect of CR in AAD consisting of a modestly improved exercise capacity and work load during cycle cardiopulmonary exercise test (TB-AAD), and improved quality of life (QoL). No adverse events were reported during symptom limited pre-CR treadmill or cycle exercise VO max or CR. Given the overall potential in this high risk population without adequate evidence for important variables such as safe time from post-op to CR, intensity of training, duration and frequency of sessions and followup it is time for a moderate sized well designed safe trial for patients' post-op surgery for TA-AAD and medically treated TB-AAD who are treated with standardized evidence based medical therapy and physical therapy from discharge randomized to CR versus usual care. PROSPERO registry ID: CRD42023392896.
