Meta-Analysis Review
BACKGROUND
Venous sinus thromboses (VSTs) are rare complications of neurosurgical procedures in the proximity of the dural sinuses. Surgery of the posterior cranial fossa (PCF) and particularly of the cerebellopontine angle (CPA) shows increased risk of VST. VST management is challenging because anticoagulant therapy must be balanced with the risk of postoperative bleeding. We performed a systematic review and meta-analysis to summarize the most important neuroradiologic and clinical aspects of VST after PCF/CPA surgery.
METHODS
We performed a comprehensive literature search to identify articles reporting data on VST after PCF/CPA surgery. We selected only comparative studies providing adequate neuroimaging assessing VST and a control group.
RESULTS
We included 13 articles reporting 1855 patients. VST occurred in 251/1855 cases (estimated incidence, 17.3%; 95% confidence interval [CI], 12.4%-22.2%). Only presigmoid approach (odds ratio [OR], 2.505; 95% CI, 1.161-5.404; P = 0.019) and intraoperative sinus injury (OR, 8.95; 95% CI, 3.43-23.34; P < 0.001) showed a significant association with VST. VST-related symptoms were reported in 12/251 patients with VST (pooled incidence, 3.1%; 95% CI, 1%-5.2%). In particular, we found a significantly increased OR of cerebrospinal fluid leak (OR, 3.197; 95% CI, 1.899-5.382; P < 0.001) and cerebrospinal fluid dynamic alterations in general (OR, 3.625; 95% CI, 2.370-5.543; P < 0.001). Indications for VST treatment were heterogeneous: 58/251 patients underwent antithrombotics, with 6 treatment-related bleedings. Recanalization overall occurred in 56.4% (95% CI, 40.6%-72.2%), with no significant difference between treated and untreated patients. However, untreated patients had a favorable outcome.
CONCLUSIONS
VST is a relatively frequent complication after PCF/CPA surgery and a presigmoid approach and intraoperative sinus injury represent the most significant risk factors. However, the clinical course is generally benign, with no advantage of antithrombotic therapy.

Review
BACKGROUND
Suspension trauma syndrome is a life-threatening event that occurs when a person is "trapped" in a prolonged passive suspension. It is most commonly seen in people who engage in occupational or sport activities that require harness suspension. The aim of this study is to identify the predisposing factors, pathophysiology, and management of suspension trauma.
METHODS
A review and analysis of the literature published in English and Spanish from 1972 to 2020 on suspension trauma were performed. Search sources were PubMed, Medline, Cochrane Library, MeSH, UpToDate, and Google Scholar. Articles referring to suspension trauma associated with other injury mechanisms (traumatic impact injuries, drowning, asphyxiation, or bleeding), case reports, and pediatric population were excluded.
RESULTS
Forty-one articles were identified. Of these, 29 articles related to mechanism, pathophysiology, and management of individuals who suffered prolonged suspension trauma without associated traumatic injuries were included in the study. We encountered several controversies describing the putative pathophysiology, ranging from blood sequestration in the lower extremities versus accumulation of metabolic waste and hyperkalemia to dorsal hook-type harness as a trigger cause of positional asphyxia; to vascular compression of femoral vessels exerted by the harness causing decreased venous return. Pstients suspended in a full-body harness with dorsal hook showed more hemodynamic alterations in response to the compressive effect on the rib cage, causing a reduction in perfusion by presenting a decrease in pulse pressure. Management strategies varied across studies.
CONCLUSIONS
Progress has been made in individualizing the population at risk and in the management of suspension trauma. We recommend the formation of consensus definitions, larger cohort or registry studies to be conducted, and experimental animal models to better understand the mechanisms in order to develop management and life support guidelines from a trauma and emergency medicine perspective.

BACKGROUND
The limited availability of balloon sizes for cryoballoon leads to anatomical limitations for pulmonary vein (PV) isolation. We conducted a comprehensive systematic analysis on procedural success rate, atrial fibrillation (AF) recurrence rate and complications of cryoballoon ablation in association with the anatomy of the left atrium and PV based on preprocedural CT to gain insights into proper treatments of patients with AF using cryoballoon.
METHOD
A systematic search of literature databases, including PubMed, Web of Science and Cochrane Library, from the inception of each database through February 2021 was conducted. Search keywords included 'atrial fibrillation', 'cryoballoon ablation' and 'anatomy'.
RESULTS
Overall, 243 articles were identified. After screening, 16 articles comprising 1396 patients were included (3, 5 and 8 for acute success, AF recurrence and complications, respectively). Regarding acute success and AF recurrences, thinner width of the left lateral ridge, higher PV ovality, PV ostium-bifurcation distance, shorter distance from the non-coronary cusp to inferior PVs, shallower angle of right PVs against the atrial septum and larger right superior PV (RSPV) were associated with poor outcomes. Regarding complications, shorter distance between the RSPV ostium and the right phrenic nerve, larger RSPV-left atrium angle, larger RSPV area and smaller right carina width were associated with incidences of phrenic nerve injury.
CONCLUSION
This study elucidated several key anatomical features of PVs possibly affecting acute success, AF recurrence and complications in patients with AF using cryoballoon ablation. CT analysis has helped to describe benefits and anatomical limitations for cryoballoon ablation.

Meta-Analysis Review
BACKGROUND
Pulmonary cement embolism (PCE) was a rare but fatal complication for percutaneous vertebral augmentation (PVA). Thus we did a systematic review and meta-analysis of cohort studies to investigate the risk factors for PCE after PVA.
METHODS
We systematically searched PubMed, EMBASE, Cochrane library, Google Scholar, web of science, and ClinicalTrial.gov from the establishment of the database to September 2021. All eligible studies assessing the risk factors for PCE after PVA were incorporated. Dichotomous data was calculated by risk difference (RD) from Mantel-Haenszel method (M - H method); continuous data was analyzed by mean difference (MD) from Inverse-Variance method (I-V method). All variables were taken as measure of effect by fixed effect model. Heterogeneity, sensitivity, and publication bias analyses were also performed.
RESULTS
This study totally included 13 studies. According to the Newcastle-Ottawa Scale (NOS), 7 studies were considered as low quality, with NOS< 6. The others were of relatively high quality, with NOS≥6. 144/6251 patients (2.3%) had PCE after PVA. percutaneous vertebroplasty (PVP) (RD = 0.02, 95%CI: [0.01, 0.04], Z = 3.70, P < 0.01), thoracic vertebra (RD = 0.03, 95%CI: [0.01, 0.05], Z = 3.53, P < 0.01), higher cement volume injected per level (MD = 0.23, 95%CI: [0.05, 0.42], Z = 2.44, P = 0.01), more than three vertebrae treated per session (MD = -0.05, 95%CI: [-0.08, -0.02], Z = 3.65, P < 0.01), venous cement leakage (RD = 0.07, 95%CI: [0.03, 0.11], Z = 3.79, P < 0.01) were more likely to cause PCE.
CONCLUSION
This study showed that risk factors for PCE included PVP, thoracic vertebra, higher cement volume injected per level, more than three vertebrae treated per session, venous cement leakage. As a serious complication, PCE should be paid attention and avoided.

BACKGROUND
Thromboprophylaxis can reduce the risk of venous thromboembolism (VTE) during lower-limb immobilisation, but it is unclear whether or not this translates into meaningful health benefit, justifies the risk of bleeding or is cost-effective. Risk assessment models (RAMs) could select higher-risk individuals for thromboprophylaxis.
OBJECTIVES
To determine the clinical effectiveness and cost-effectiveness of different strategies for providing thromboprophylaxis to people with lower-limb immobilisation caused by injury and to identify priorities for future research.
DATA SOURCES
Ten electronic databases and research registers (MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Database of Abstracts of Review of Effects, the Cochrane Central Register of Controlled Trials, Health Technology Assessment database, NHS Economic Evaluation Database, Science Citation Index Expanded, ClinicalTrials.gov and the International Clinical Trials Registry Platform) were searched from inception to May 2017, and this was supplemented by hand-searching reference lists and contacting experts in the field.
REVIEW METHODS
Systematic reviews were undertaken to determine the effectiveness of pharmacological thromboprophylaxis in lower-limb immobilisation and to identify any study of risk factors or RAMs for VTE in lower-limb immobilisation. Study quality was assessed using appropriate tools. A network meta-analysis was undertaken for each outcome in the effectiveness review and the results of risk-prediction studies were presented descriptively. A modified Delphi survey was undertaken to identify risk predictors supported by expert consensus. Decision-analytic modelling was used to estimate the incremental cost per quality-adjusted life-year (QALY) gained of different thromboprophylaxis strategies from the perspectives of the NHS and Personal Social Services.
RESULTS
Data from 6857 participants across 13 trials were included in the meta-analysis. Thromboprophylaxis with low-molecular-weight heparin reduced the risk of any VTE [odds ratio (OR) 0.52, 95% credible interval (CrI) 0.37 to 0.71], clinically detected deep-vein thrombosis (DVT) (OR 0.40, 95% CrI 0.12 to 0.99) and pulmonary embolism (PE) (OR 0.17, 95% CrI 0.01 to 0.88). Thromboprophylaxis with fondaparinux (Arixtra, Aspen Pharma Trading Ltd, Dublin, Ireland) reduced the risk of any VTE (OR 0.13, 95% CrI 0.05 to 0.30) and clinically detected DVT (OR 0.10, 95% CrI 0.01 to 0.94), but the effect on PE was inconclusive (OR 0.47, 95% CrI 0.01 to 9.54). Estimates of the risk of major bleeding with thromboprophylaxis were inconclusive owing to the small numbers of events. Fifteen studies of risk factors were identified, but only age (ORs 1.05 to 3.48), and injury type were consistently associated with VTE. Six studies of RAMs were identified, but only two reported prognostic accuracy data for VTE, based on small numbers of patients. Expert consensus was achieved for 13 risk predictors in lower-limb immobilisation due to injury. Modelling showed that thromboprophylaxis for all is effective (0.015 QALY gain, 95% CrI 0.004 to 0.029 QALYs) with a cost-effectiveness of £13,524 per QALY, compared with thromboprophylaxis for none. If risk-based strategies are included, it is potentially more cost-effective to limit thromboprophylaxis to patients with a Leiden thrombosis risk in plaster (cast) [L-TRiP(cast)] score of ≥ 9 (£20,000 per QALY threshold) or ≥ 8 (£30,000 per QALY threshold). An optimal threshold on the L-TRiP(cast) receiver operating characteristic curve would have sensitivity of 84-89% and specificity of 46-55%.
LIMITATIONS
Estimates of RAM prognostic accuracy are based on weak evidence. People at risk of bleeding were excluded from trials and, by implication, from modelling.
CONCLUSIONS
Thromboprophylaxis for lower-limb immobilisation due to injury is clinically effective and cost-effective compared with no thromboprophylaxis. Risk-based thromboprophylaxis is potentially optimal but the prognostic accuracy of existing RAMs is uncertain.
FUTURE WORK
Research is required to determine whether or not an appropriate RAM can accurately select higher-risk patients for thromboprophylaxis.

There is increasing evidence that novel coronavirus disease 2019 (COVID-19) leads to a significant coagulopathy, a phenomenon termed "COVID-19 associated coagulopathy." COVID-19 has been associated with increased rates of both venous and arterial thromboembolic events, a source of significant morbidity and mortality in this disease. Further evidence suggests a link between the inflammatory response and coagulopathy associated with COVID-19. This presents a unique set of challenges for diagnosis, prevention, and treatment of thrombotic complications. In this review, we summarize and discuss the current literature on laboratory coagulation disruptions associated with COVID-19 and the clinical effects of thromboembolic events including pulmonary embolism, deep vein thrombosis, peripheral arterial thrombosis, and acute ischemic stroke in COVID-19. Endothelial injury and augmented innate immune response are implicated in the development of diffuse macro- and microvascular thrombosis in COVID-19. The pathophysiology of COVID-19 associated coagulopathy is an important determinant of appropriate treatment and monitoring of these complications. We highlight the importance of diagnosis and management of dysregulated coagulation in COVID-19 to improve outcomes in COVID-19 patients with thromboembolic complications.

Review
Wound irrigation versus swabbing technique for cleansing noninfected chronic wounds: A systematic review of differences in bleeding, pain, infection, exudate, and necrotic tissue.
PURPOSE
To systematically summarize and review the existing literature to determine the difference between wound cleansing techniques, irrigation and swabbing, in relation to bleeding, pain, infection, necrotic tissue and exudate in non-infected chronic wounds including pressure injuries, venous and arterial leg ulcers and diabetic foot ulcers.
METHODS
A systematic search of the electronic databases Ovid Medline, Cochrane Database of Systematic Reviews, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and EMBASE was performed to identify all relevant literature in English. The search also included systematic reviews as a method to obtain additional potential citations by manually searching the reference lists. Included studies were assessed for methodological quality using the Cochrane Risk of Bias Tool.
RESULTS
One study met eligibility criteria. Two hundred fifty six patients with wounds healing via secondary intention (n = 256) were included. Wound cleansing via swabbing technique was associated with increased perception of pain and increased rates of infection when compared to the irrigation group (93.4% versus 84.2% p = 0.02 and 5.2% versus 3.3% p = 0.44, respectively). Only a small proportion of this sample met the inclusion criteria, so the results are not considered externally valid.
CONCLUSION
Wound cleansing remains a controversial topic. Despite calls for further research, there continues to remain a large gap in evidence to guide practice. Irrigation continues to replace swabbing in the management of chronic wounds, although evidence of improved outcomes is virtually nonexistent. Although the one study identified was of sound methodological quality, chronic wounds accounted for only a small percentage of the sample. Therefore, results are not generalizable to those with chronic wounds. Further research is needed to determine the effectiveness of basic wound cleansing techniques before considering more costly products.

Meta-Analysis
Timing of pharmacologic venous thromboembolism prophylaxis initiation for trauma patients with nonoperatively managed blunt abdominal solid organ injury: a systematic review and meta-analysis.
BACKGROUND
Blunt abdominal solid organ injury is common and is often managed nonoperatively. Clinicians must balance risk of both hemorrhage and thrombosis. The optimal timing of pharmacologic venous thromboembolism prophylaxis (VTEp) initiation in this population is unclear. The objective was to evaluate early (< 48 h) compared to late initiation of VTEp in adult trauma patients with blunt abdominal solid organ injury managed nonoperatively.
METHODS
Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials were searched from inception to March 2021. Studies comparing timeframes of VTEp initiation were considered. The primary outcome was failure of nonoperative management (NOM) after VTEp initiation. Secondary outcomes included risk of transfusion, other bleeding complications, risk of deep vein thrombosis (DVT) and pulmonary embolism, and mortality.
RESULTS
Ten cohort studies met inclusion criteria, with a total of 4642 patients. Meta-analysis revealed a statistically significant increase in the risk of failure of NOM among patients receiving early VTEp (OR 1.76, 95% CI 1.01-3.05, p = 0.05). There was no significant difference in risk of transfusion. Odds of DVT were significantly lower in the early group (OR 0.36, 95% CI 0.22-0.59, p < 0.0001). There was no difference in mortality (OR 1.50, 95% CI 0.82-2.75, p = 0.19). All studies were at serious risk of bias due to confounding.
CONCLUSIONS
Initiation of VTEp earlier than 48 h following hospitalization is associated with an increased risk of failure of NOM but a decreased risk of DVT. Absolute failure rates of NOM are low. Initiation of VTEp at 48 h may balance the risks of bleeding and VTE.

Meta-Analysis
OBJECTIVE
The aim of this meta-analysis was to compare the functional outcomes and complications of external fixation (EF) versus open reduction and internal fixation (ORIF) in the treatment of complex tibial plateau fractures.
METHODS
Based on a comprehensive search of major databases through PubMed, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL), 19 studies comparing EF versus ORIF in treatment of complex tibial plateau fractures (Schatzker V-VI/ OTA C1, C2, and C3) were included in the studies. There was one randomized controlled trial, two prospective comparative studies, 14 retrospective comparative studies, and two conference papers. From these studies, the data regarding functional and surgical outcomes as well as complications were obtained and pooled to conduct a comparison between the two methods of treatment.
RESULTS
1191 tibial plateau fractures were determined by the systematic review. Of those fractures, 543 were treated using EF, and 648 were treated using ORIF with plate and screws. All the studies included the young patients with traumatic tibial plateau fractures with mean ages from 40 to 60 years. The analysis of pooled data revealed significantly better functional outcome in patients operated with EF (standard mean difference [SMD] = 0.29, 95% confidence interval [CI] = 0.04-0.55, P = 0.02, I2= 0%). However, according to categorical functional outcomes, no significant differences were found (OR 0.80, 95%CI: 0.47, 1.34, P=0.39, I2= 31%). The range of movement at the knee joint was significantly better in patients treated by EF (mean difference [MD] = 7.86, 95%CI = 3.56 -12.17, P = 0.0003). The surgical time in the EF group was significantly shorter compared to the ORIF group (MD = -52.11, 95%CI = -99.62-(-4.60), P = 0.03). Similarly, the intraoperative blood loss was significantly lesser in the EF group (MD = -341.53, 95%CI = -528.18- (-154.88), P = 0.0003). Although the superficial infection was more frequent in the EF group (odds ratio [OR] = 3.22, P = 0.0002), there were no differences in the deep infection and overall infection rates. Also, there were no differences in reoperation rate, knee stiffness, compartment syndrome, and venous thromboembolism. The radiographic osteoarthritis was more common in the EF group (OR = 1.56, P = 0.04); however, there was no difference in the need for total knee arthroplasty between the two treatment modalities.
CONCLUSION
EF provides better functional outcomes and range of motion compared to ORIF in the treatment of complex tibial plateau fractures. With shorter surgical time and lesser intraoperative blood loss, EF can be considered as a definite treatment method in open injuries, polytrauma patients, and chronically morbid patients who cannot withstand prolonged surgery.

Critical Care Explorations May 2021To compare different modalities of renal replacement therapy in critically ill adults with acute kidney injury. (Review)
Review
OBJECTIVES
To compare different modalities of renal replacement therapy in critically ill adults with acute kidney injury.
DATA SOURCES
We searched Medline, PubMed, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov from inception to 25 May, 2020. We included randomized controlled trials comparing the efficacy and safety of different renal replacement therapy modalities in critically ill patients with acute kidney injury.
STUDY SELECTION
Ten reviewers (working in pairs) independently screened studies for eligibility, extracted data, and assessed risk of bias.
DATA EXTRACTION
We performed random-effects frequentist network meta-analyses and used the Grading of Recommendations, Assessment, Development, and Evaluation approach to assess certainty of evidence. The primary analysis was a four-node analysis: continuous renal replacement therapy, intermittent hemodialysis, slow efficiency extended dialysis, and peritoneal dialysis. The secondary analysis subdivided these four nodes into nine nodes including continuous veno-venous hemofiltration, continuous veno-venous hemodialysis, continuous veno-venous hemodiafiltration, continuous arterio-venous hemodiafiltration, intermittent hemodialysis, intermittent hemodialysis with hemofiltration, slow efficiency extended dialysis, slow efficiency extended dialysis with hemofiltration, and peritoneal dialysis. We set the minimal important difference threshold for mortality as 2.5% (relative difference, 0.04).
DATA SYNTHESIS
Thirty randomized controlled trials ( = 3,774 patients) proved eligible. There may be no difference in mortality between continuous renal replacement therapy and intermittent hemodialysis (relative risk, 1.04; 95% CI, 0.93-1.18; low certainty), whereas continuous renal replacement therapy demonstrated a possible increase in mortality compared with slow efficiency extended dialysis (relative risk, 1.06; 95% CI, 0.85-1.33; low certainty) and peritoneal dialysis (relative risk, 1.16; 95% CI, 0.92-1.49; low certainty). Continuous renal replacement therapy may increase renal recovery compared with intermittent hemodialysis (relative risk, 1.15; 95% CI, 0.91-1.45; low certainty), whereas both continuous renal replacement therapy and intermittent hemodialysis may be worse for renal recovery compared with slow efficiency extended dialysis and peritoneal dialysis (low certainty). Peritoneal dialysis was probably associated with the shortest duration of renal support and length of ICU stay compared with other interventions (low certainty for most comparisons). Slow efficiency extended dialysis may be associated with shortest length of hospital stay (low or moderate certainty for all comparisons) and days of mechanical ventilation (low certainty for all comparisons) compared with other interventions. There was no difference between continuous renal replacement therapy and intermittent hemodialysis in terms of hypotension (relative risk, 0.92; 95% CI, 0.72-1.16; moderate certainty) or other complications of therapy, but an increased risk of hypotension and bleeding was seen with both modalities compared with peritoneal dialysis (low or moderate certainty). Complications of slow efficiency extended dialysis were not sufficiently reported to inform comparisons.
CONCLUSIONS
The results of this network meta-analysis suggest there is no difference in mortality between continuous renal replacement therapy and intermittent hemodialysis although continuous renal replacement therapy may increases renal recovery compared with intermittent hemodialysis. Slow efficiency extended dialysis with hemofiltration may be the most effective intervention at reducing mortality. Peritoneal dialysis is associated with good efficacy, and the least number of complications however may not be practical in all settings. Importantly, all conclusions are based on very low to moderate certainty evidence, limited by imprecision. At the very least, ICU clinicians should feel comfortable that the differences between continuous renal replacement therapy, intermittent hemodialysis, slow efficiency extended dialysis, and, where clinically appropriate, peritoneal dialysis are likely small, and any of these modalities is a reasonable option to employ in critically ill patients.
