Meta-Analysis
OBJECTIVE
This meta-analysis was performed to investigate the correlation between von Willebrand factor (vWF) antigen and hepatic venous pressure gradient (HVPG) and to evaluate the diagnostic performance of vWF to detect clinically significant portal hypertension (CSPH) and severe portal hypertension (SPH).
DESIGN
Systematic review and meta-analysis.
METHODS
MEDLINE, EMBASE, Web of Science and the Cochrane Library were screened up to 5 April 2018. Studies related to the diagnostic performance of vWF to detect CSPH and/or SPH with HVPG as the reference standard were included. Study quality was assessed by using the Quality Assessment of Diagnostic Accuracy Studies scale. Two authors independently used a standardised form to extract data.
OUTCOMES
The primary outcome was the correlation coefficient between vWF and HVPG. The secondary outcome was the diagnostic performance of vWF to detect CSPH or SPH.
RESULTS
A total of six articles involving 994 patients were included in this study. Five of the included articles were used to stratify the results for the correlation coefficient, three for the diagnostic performance of CSPH and two for SPH. The pooled correlation coefficient based on the random effects model was 0.54 (95% CI 0.35 to 0.69), thus suggesting a moderate correlation between vWF and HVPG. The pooled sensitivity, specificity and area under the curve of vWF for CSPH detection were 82% (95% CI 78 to 86), 76% (95% CI 68 to 83) and 0.87 (95% CI 0.80 to 0.94), respectively. Regarding the ability of vWF to detect SPH, the pooled sensitivity and specificity were 86% (95% CI 80 to 90) and 75% (95% CI 66 to 83), respectively. These results supported the satisfactory diagnostic performance of vWF for CSPH and SPH detection.
CONCLUSIONS
vWF, as a novel biomarker, has a moderate correlation with HVPG and shows a satisfactory performance for the diagnosis of CSPH and SPH in patients with cirrhosis.

Review
BACKGROUND
This comprehensive systematic review aims to assess the literature regarding the risk of postoperative complications in patients undergoing total joint arthroplasty (TJA) with concomitant thyroid dysfunction.
METHODS
Studies were identified by searching PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, and ClinicalTrials.gov (end of search: May 2022).
INCLUSION CRITERIA
Randomized control and case-control studies, cohort and observational clinical studies were included, which focused on postoperative complications and outcomes of patients undergoing TJA operations of major joints (knee, hip, ankle, elbow). All studies were assessed according to their level of evidence, the number and age of patients, and treatment complications.
ANALYSIS
Nine studies were included in this review that demonstrated a higher risk of postoperative anemia, perioperative blood loss, hemoglobin decrease, and transfusion rates in hypothyroid patients after TJA.
RESULTS
Hypothyroidism has been identified as a potential but modifiable risk factor for increased rates of deep venous thrombosis, acute kidney injury, pneumonia, and non-specified cardiac complications among hypothyroid patients who underwent TJA as well as increased rates of periprosthetic joint infection. No significant differences in the prosthesis-related mechanical complication rates have been calculated when comparing hypothyroid and euthyroid patients.

Meta-Analysis
INTRODUCTION
We aimed to describe the extrapulmonary manifestations of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, including their frequency, onset with respect to respiratory symptoms, pathogenesis and association with disease severity.
METHODS
We searched the MEDLINE and Embase databases for SARS-CoV-2-related studies. Meta-analysis, observational studies, case series and case reports published in English or Chinese between 1 January 2020 and 1 May 2020 were included. Reports with only paediatric or obstetric cases were excluded.
RESULTS
169 articles were included. Early manifestations (preceding respiratory symptoms until Day 6 of onset) included olfactory and gustatory disturbance (self-reported in up to 68% and 85% of cases, respectively), gastrointestinal symptoms (up to 65.9%) and rash (up to 20.4%). From Day 7 onwards, hypercytokinaemia, paralleled multi-organ complications including acute cardiac injury (pooled incidence of 17.7% in 1,412 patients, mostly with severe disease and 17.4% mortality), kidney and liver injury (up to 17% and 33%, respectively) and thrombocytopenia (up to 30%). Hypercoagulability resulted in venous thromboembolic events in up to 31% of all patients. Uncommon disease presentation and complications comprised Guillain-Barré syndrome, rhabdomyolysis, otitis media, meningoencephalitis and spontaneous pneumomediastinum.
CONCLUSION
Although the systemic manifestations of SARS-CoV-2 infection are variegated, they are deeply interwoven by shared mechanisms. Two phases of extrapulmonary disease were identified: (a) an early phase with possible gastrointestinal, ocular and cutaneous involvement; and (b) a late phase characterised by multiorgan dysfunction and clinical deterioration. A clear, multidisciplinary consensus to define and approach thromboinflammation and cytokine release syndrome in SARS-CoV-2 is needed.

Meta-Analysis
BACKGROUND
Total hip arthroplasty (THA) relieves pain and restores function in patients with severe rheumatoid arthritis and osteoarthritis. Over the past few decades, several authors have attempted to assess the efficacy and safety of simultaneous bilateral THA compared with staged bilateral THA. The purpose of this meta-analysis is to compare the mortalities and complications between simultaneous bilateral THA and staged bilateral THA.
METHODS
A literature search to identify eligible studies was undertaken to identify all relevant articles published until August 2018. We included studies that compared simultaneous bilateral THA and staged bilateral THA and their effects on mortality and complications. The outcomes included mortality, the occurrence of deep venous thrombosis (DVT), the occurrence of pulmonary embolism (PE), respiratory complications, cardiovascular complications, digestive system complications and the occurrence of dislocation. Stata 12.0 was used for the meta-analysis.
RESULTS
Nineteen studies involving 59,257 patients were identified; among them, 16,758 patients were selected for treatment with simultaneous bilateral THA, and 42,499 patients were chosen for the purpose of staged bilateral THA. The meta-analysis results demonstrated that there was no significant difference between simultaneous bilateral THA and staged bilateral THA in terms of mortality (risk ratio [RR] = 1.15, 95% CI = 0.76, 1.74; P = .520). Compared with staged bilateral THA, simultaneous bilateral THA was associated with a reduction in the occurrence of DVT, PE and respiratory complications (P < .05). There were no significant differences in the cardiovascular complications, digestive system complications or the occurrence of dislocation and infection (P = .057).
CONCLUSIONS
We observed that the prevalence of DVT, PE and respiratory complications was considerably lower with the use of simultaneous bilateral THA than with the use of staged bilateral THA. Thus, simultaneous bilateral THA is a considerably safer procedure than staged bilateral THA in selected THA patients.

Meta-Analysis
AIMS
The primary objective of this review was to determine whether tranexamic acid (TXA) reduces transfusion rates in patients undergoing surgery for hip fractures. The secondary objective was to assess the effects of TXA on mortality and thromboembolic events in the same cohort.
METHODS
A systematic review of electronic databases was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We included randomized controlled trials comparing perioperative TXA in patients treated surgically for hip/proximal femoral fractures against placebo. The primary outcome was the proportion of patients requiring blood transfusion. Secondary outcomes were blood loss, mortality, and complications. Meta-analysis was performed using inverse variance and random effects model.
RESULTS
The pooled data from 10 studies involving 842 patients showed that the proportion of patients requiring blood transfusion was significantly less in the TXA group (risk ratio (RR) 0.72, 95% confidence interval (CI) 0.59-0.88). There was no difference between TXA and control groups when comparing mortality (RR 1.17, 95% CI 0.65-2.10), deep venous thrombosis (RR 1.14, 95% CI 0.43-3.06), pulmonary embolism (RR 0.53, CI 0.09-3.02), acute coronary syndrome (RR 1.52, CI 0.18-12.98), cerebrovascular events (RR 0.78, CI 0.16-3.68), or wound complications (RR 1.61, CI 0.51-5.13).
CONCLUSION
There is evidence that TXA reduces the proportion of patients requiring blood transfusions when undergoing hip fracture surgery. However, the small sample size and low event rates for adverse effects preclude any definitive conclusions from being established regarding adverse effects. Future trials should be powered to further assess potential complications and determine the ideal dosage and regime.

BACKGROUND AND AIMS
The venous excess ultrasound (VExUS) score presents a prospect of valuable clinical utility. The study aimed to systematically review the effectiveness of the VExUS score in detecting venous congestion across emergency, critical care, and peri-operative contexts; assessing its utility in improved patient outcomes; and exploring its relationship with established parameters.
METHODS
This systematic review was registered in the International Prospective Register of Systematic Reviews (CRD42023421034). A comprehensive literature search, employing pre-defined search terms related to the VExUS score in diverse clinical contexts, was conducted on articles published between 2000 and 15 May 2023 across databases- PubMed, PubMed Central, Cochrane, Scopus, Elsevier Clinical Key, and Google Scholar. Bias risk assessment was carried out using the Risk of Bias in Non-Randomised Studies tool. Given the significant heterogeneity across studies concerning participants, interventions, outcomes, and study designs, data pooling for a meaningful meta-analysis was not feasible.
RESULTS
The review included 15 articles comprising observational studies, case series, and case reports. Most patients exhibited moderate-to-severe venous congestion based on their baseline VExUS scores. Higher VExUS scores correlated with a greater risk of acute kidney injury (AKI) in post-operative patients. The VExUS score strongly correlated with central venous pressure; specific components, such as the intra-renal monophasic pattern, portal-pulsatility, and inferior vena cava diameter, exhibited robust predictive value for venous congestion.
CONCLUSION
VExUS score is valuable in assessing and predicting venous congestion, especially regarding AKI prediction risk and guiding interventions. However, its utility in predicting outcomes in acute heart failure patients appears less certain.

Catheter ablation is a treatment modality which has been increasingly used for cardiac arrhythmias. However, it is not complication-free, and cardiac perforation is one of its most life-threatening complications. As surgery is usually not the first-line treatment for this emergent episode, there were only very few sporadic surgical reports in the literature. This systemic review primarily aims to collect different surgical approaches for catheter-induced cardiac perforation to help surgeons manage this kind of uncommon and critical patients. Of the 452 initially screened articles, 22 studies (38 patients) were included in the systemic review. Of all the included patients, 84% (32/38) were found to have pericardial effusion acutely following catheter-related procedures, and 16% (6/38) experienced delayed-onset episodes. Regarding the surgical procedures, four patients underwent removal of clots only, eight patients underwent suture repair of the left ventricle (LV), nine patients underwent suture repair of the right ventricle (RV), five patients underwent suture repair of the LA, and four patients underwent sutureless repair of the LV and pulmonary vein (LV 1, RV 1, pulmonary vein 1). In addition to repair of perforation sites, the concomitant combined procedures included repair of intercostal vessels (complication of pericardiocentesis) for one patient, cryoablation for two patients, and maze procedure for one patient. For cardiac perforation following catheter ablation or electrophysiology study, although the majority of the patients are treated with pericardiocentesis and medical management at first, cardiovascular surgeons have to prepare to take over if the bleeding is persistent or if the cardiac tamponade is not relieved.

Meta-Analysis
CONTEXT
Patients with spinal cord injury (SCI) are at high risk for venous thromboembolism (VTE). The risk factors for VTE in patients with SCI are complex.
OBJECTIVE
This meta-analysis was conducted to clarify the risk factors for VTE in patients with SCI.
METHODS
The Cochrane Library, PubMed, EBSCO, Web of Science, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM), Wanfang Med Data Database, and VIP Database were searched to identify studies reporting on risk factors for VTE in patients with SCI.
RESULTS
The meta-analysis included 25 studies. Findings showed that risk of VTE in patients with SCI was significantly associated with middle- and old-age (OR = 2.08, 95%CI, 1.47, 2.95), male sex (OR = 1.41, 95%CI, 1.26, 1.59), complete paralysis (OR = 3.69, 95%CI, 2.60, 5.24), personal/family history of venous thrombosis (OR = 1.95, 95%CI, 1.35, 2.81), history of smoking (OR = 2.67, 95%CI, 1.79, 3.98), lack of compression therapy (OR = 2.44, 95%CI, 1.59, 3.73), presence of lower limb/pelvic fracture (OR = 3.47, 95%CI, 1.79, 6.75), paraplegia (OR = 1.81, 95%CI, 1.49, 2.19), and diabetes (OR = 4.24, 95%CI, 2.75, 6.52).
CONCLUSION
The meta-analysis identified 9 risk factors for VTE in patients with SCI. Healthcare providers should be aware of the risk factors for VTE when rehabilitating patients with SCI.

Review
Cephalomedullary Nailing has a Higher Reoperation Rate Compared to Sliding Hip Screw Fixation in the Treatment of Intertrochanteric Femur Fractures: A Systematic Literature Review and Meta-analysis.
OBJECTIVES
Intertrochanteric hip fractures are a common orthopaedic injury in the United States. Complications of surgical treatment include nonunion, lag screw cutout, implant failure, post-operative pain, risk of refracture or reoperation, and infection. The purpose of this study was to compare the rate of complications of sliding hip screw fixation (SHS) compared to cephalomedullary nailing (CMN) for the treatment of closed intertrochanteric femur fractures in adult patients.
METHODS
PubMed, CINAHL, and Cochrane Library databases were searched for studies comparing SHS to CMN in the treatment of closed intertrochanteric femur fractures in adults. Data were compiled to observe the rate of nonunion, cutout failure, infection, refracture, perioperative blood loss, reoperation, postoperative pain, pulmonary embolism/deep venous thrombosis (DVT), length of hospital stay, and mortality.
RESULTS
Seventeen studies were included comprising 1,500 patients treated with SHS and 1,890 patients treated with CMN. Treatment of intertrochanteric femur fractures with SHS demonstrated significantly fewer refractures and reoperations. There was no significant difference in other variables between SHS and CMN treated groups.
CONCLUSION
This meta-analysis shows that the only notable difference in outcomes is patients treated with CMN have a higher rate of refracture and reoperation. With new advances in the development of both CMNs and SHS, further studies will be required to see if these differences persist in the coming years.

BACKGROUND
Although several complications of proximal hamstring tendon ruptures have been reported in the literature, few studies have comprehensively analyzed the complication profile of proximal hamstring tendon repair.
PURPOSE
To identify the overall rate of complications following proximal hamstring tendon repair and to differentiate these complications into categories.
STUDY DESIGN
Systematic review; Level of evidence, 4.
METHODS
Included in this review were studies that examined surgical repair of proximal hamstring tendon ruptures; all studies were in English and had an evidence level of 4 or higher. No restrictions were made regarding publication date or methodological quality. Data regarding complications were extracted to calculate the overall complication rate as well as the rate of major and minor complications. A quantitative data synthesis was conducted using the chi-square test to compare the proportion of patients who experienced complications with the endoscopic versus open approach.
RESULTS
A total of 43 articles including 2833 proximal hamstring tendon repairs were identified. The overall postoperative complication rate was 15.3% (n = 433). The rate of major complications was 4.6%, including a 1.7% rate of sciatic nerve injury, 0.8% rate of venous thromboembolism, 0.8% reoperation rate, 0.8% rerupture rate, and 0.4% rate of deep infection. Minor complications included a 2.4% rate of posterior femoral cutaneous nerve injury, 2.3% rate of persistent hamstring myopathy, 2.2% rate of persistent sitting pain, 1.8% rate of peri-incisional numbness, 1.1% rate of superficial infection, and 0.8% rate of hematoma/seroma.
CONCLUSION
Proximal hamstring tendon repair is associated with an overall complication rate of 15.3%, including a 4.6% rate of major complications.
