Review
PURPOSE
To summarize the incidence, risk factors, diagnosis methods, prophylaxis methods, and treatment of venous thromboembolism (VTE) following arthroscopic shoulder surgery.
METHODS
Literature on VTE after arthroscopic shoulder surgeries was summarized, and all primary full-text articles reporting at least 1 case of deep vein thrombosis (DVT) or pulmonary embolism (PE) after arthroscopic shoulder surgeries were included. Articles were critically appraised and systematically analyzed to determine the incidence, risk factors, diagnosis, prophylaxis, and management of VTE following arthroscopic shoulder surgeries.
RESULTS
This study included 42 articles in which the incidence of VTE ranges from 0 to 5.71% and the overall incidence was 0.26%. Most VTE events took place between the operation day and the 14th day after the operation (35/51). Possible risk factors included advanced age (> 70 years), obesity (BMI ≥ 30 kg/m), diabetes mellitus, thrombophilia, history of VTE, prolonged operation time, hormone use, and immobilization after surgery. The most common prophylaxis method was mechanical prophylaxis (13/15). No statistical difference was detected when chemoprophylaxis was applied. The management included heparinization followed by oral warfarin, warfarin alone and rivaroxaban, a direct oral anticoagulant.
CONCLUSION
Based on the included studies, the incidence rate of VTE after arthroscopic shoulder surgeries is relatively low. The risk factors for VTE are still unclear. CT/CTA and ultrasound were the mainstream diagnosis methods for PE and DVT, respectively. Current evidence shows that chemical prophylaxis did not deliver significant benefits, since none of the existing studies reported statistically different results. High-quality studies focusing on the prophylaxis and management of VTE population undergoing arthroscopic shoulder surgeries should be done in the future.

Meta-Analysis Review
Efficacy and safety of heparin full-dose anticoagulation in hospitalized non-critically ill COVID-19 patients: a meta-analysis of multicenter randomized controlled trials.
Arterial and venous thrombotic events in COVID-19 cause significant morbidity and mortality among patients. Although international guidelines agree on the need for anticoagulation, it is unclear whether full-dose heparin anticoagulation confers additional benefits over prophylactic-dose anticoagulation. This systematic review and meta-analysis aimed to investigate the efficacy and safety of heparin full-dose anticoagulation in hospitalized non-critically ill COVID-19 patients. We searched Pubmed/Medline, EMBASE, Clinicaltrials.gov, medRxiv.org and Cochrane Central Register of clinical trials dated up to April 2022. Randomized controlled trials (RCTs) comparing full-dose heparin anticoagulation to prophylactic-dose anticoagulation or standard treatment in hospitalized non-critically ill COVID-19 patients were included in our pooled analysis. The primary endpoint was the rate of major thrombotic events and the co-primary endpoint was the rate of major bleeding events. We identified 4 studies, all of them multicenter, randomizing 2926 patients. Major thrombotic events were 23/1524 (1.5%) in full-dose heparin anticoagulation versus 57/1402 (4.0%) in prophylactic-dose [relative risk (RR) 0.39; 95% confidence interval (CI) 0.25-0.62; p˂0.01; I = 0%]. Clinical relevant bleeding events occurred in 1.7% (26/1524) among patients treated with heparin full anticoagulation dose compared to 1.1% (15/1403) in prophylactic-dose group (RR 1.60; 95% CI 0.85-3.03; p = 0.15; I = 20%). Mortality was 6.6% (101/1524) versus 8.6% (121/1402) (RR 0.63; 95% CI 0.33-1.19; p = 0.15). In this meta-analysis of high quality multicenter randomized trials, full-dose anticoagulation with heparin was associated with lower rate of major thrombotic events without differences in bleeding risk and mortality in hospitalized non critically ill COVID-19 patients.Study registration PROSPERO, review no.

The Journal of Cardiovascular Surgery Dec 2021The main goal of this systematic review was to analyze the outcomes of acute limb ischemia (ALI) in patients suffering from the novel Coronavirus: COVID-19 (SARS-CoV-2).
INTRODUCTION
The main goal of this systematic review was to analyze the outcomes of acute limb ischemia (ALI) in patients suffering from the novel Coronavirus: COVID-19 (SARS-CoV-2).
EVIDENCE ACQUISITION
A systematic review on Medline and Embase was conducted up to May 15, 2021. All papers were sorted by abstract and full text by two independent authors. Systematic reviews, commentaries, and studies that did not distinguish status of COVID-19 infection were excluded from review. Patient demographics were recorded along with modality of treatment (endovascular and/or surgical). We analyzed 30-day outcomes, including mortality. Primary outcome was to evaluate clinical characteristic of ALI in patients affected by SARS-CoV-2 in term of location of ischemia, treatment options and 30-day outcomes.
EVINDENCE SYNTHESIS
We selected 36 articles with a total of 194 patients. Most patients were male (80%) with a median age of 60 years old. The treatment most used was thromboembolectomy (31% of all surgical interventions). A total of 32 patients (19%) were not submitted to revascularization due to critical status. The rate of technical success was low (68%), and mortality rate was high (35%).
CONCLUSIONS
This review confirms that SARS-CoV-2 is associated with a high risk of ALI. Further studies are needed to investigate the association and elucidate potential mechanisms, which may include a hypercoagulable state and hyperactivation of the immune response. Furthermore, management of ALI is not standardized and depends on patient condition and extension of the thrombosed segment. ALI in COVID-19 patients is associated with high risk of failure of revascularization and perioperative mortality.

Review
AIM
To identify and critically appraise studies of prediction models, developed using machine learning (ML) methods, for determining the optimal dosing of unfractionated heparin (UFH).
METHODS
Embase, PubMed, CINAHL, Web of Science, International Pharmaceutical Abstracts and IEEE Xplore databases were searched from inception to 31 January 2020 to identify relevant studies using key search terms synonymous with artificial intelligence or ML, 'prediction', 'dose', 'activated partial thromboplastin time (aPTT)' and 'UFH.' Studies had to have used ML methods for developing models that predicted optimal dose of UFH or target therapeutic aPTT levels in the hospital setting. The CHARMS Checklist was used to assess quality and risk of bias of included studies.
RESULTS
Of 8393 retrieved abstracts, 61 underwent full text review and eight studies met inclusion criteria. Four studies described models for predicting aPTT, three studies described models predicting optimal dose of heparin during dialysis and one study described a model that used surrogate outcomes of clotting and bleeding to predict a therapeutic aPTT. Studies varied widely in reporting of study participants, feature characterisation and selection, handling of missing data, sample size calculations and the intended clinical application of the model. Only one study conducted an external validation and no studies evaluated model impacts in clinical practice.
CONCLUSION
Studies of ML models for UFH dosing are few and none report a model ready for routine clinical use. Existing studies are limited by low methodological quality, inadequate reporting of study factors and absence of external validation and impact analysis.

Review
BACKGROUND
Venous thromboembolism is one of the major public health problems in the world. Though several studies were conducted to estimate common risk factors of venous thromboembolism and quality of anticoagulant therapy in Ethiopia, it is difficult to estimate the overall burdens of risk factors and quality of anticoagulant use because of the lack of a nationwide study.
OBJECTIVE
To assess magnitudes of risk factors of venous thromboembolism and quality of anticoagulant therapy in Ethiopia.
MATERIALS AND METHODS
Electronic searching using PubMed, EMBASE, Science Direct, Cochrane Database, Scopus, Hinari, Sci-Hub, African Journals Online Library, and Free-text Web Searches using Google Scholar was conducted from September, 15 to October 27, 2021. Each of the original studies was identified by Mesh terms and Boolean search technique using full title, various keywords and was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The data were extracted using a format prepared in Microsoft Excel and exported to STATA 14.0 for the outcome analyses.
RESULTS
The database search delivered a total of 2118 studies. After articles were removed by duplications, titles, reading the abstract, and assessed for eligibility criteria, 12 articles were found suitable for the systematic review. Prolonged immobilization (41.30%) was the most commonly observed risk factor of venous thrombosis followed by acute infection (40.25%). The proportion of therapeutic range (INR = 2-3), sub-therapeutic range (INR <2), and supra-therapeutic range (INR >3) were 32.15%, 47.58%, and 17.62%, respectively. One hundred and thirty-eight patients (11.4%) have developed minor or major bleeding complications.
CONCLUSION
Prolonged immobilization and acute infection were the main risk factors for venous thromboembolism. The quality of anticoagulant therapy in Ethiopia was poor and bleeding complications were high. A strong effort is needed to improve the quality of anticoagulation and close monitoring of patients' international normalized ratio is required to improve treatment outcomes.

Meta-Analysis
BACKGROUND
Coronavirus disease 2019 (COVID-19) is associated with hypercoagulability. It remains uncertain whether ongoing anticoagulation for atrial fibrillation (AF) in patients who later contract COVID-19 improves clinical outcomes.
OBJECTIVES
To compare chronic oral anticoagulation with no previous anticoagulation in patients with AF who contracted a COVID-19 infection concerning the outcomes of all-cause mortality, COVID-19 mortality, intensive care unit (ICU) admission, and hospitalization.
METHODS
We systematically searched PubMed, Embase, and Cochrane Library for eligible studies from inception to December 2022. We included studies comparing COVID-19 outcomes in patients with versus without prior chronic anticoagulation for AF. Risk ratios (RR) with 95% confidence intervals (CI) were pooled with a random-effects model. The level of significance was set at p < 0.05. Quality assessment and risk of bias were performed according to Cochrane recommendations.
RESULTS
Ten studies comprising 1,177,858 patients with COVID-19 and AF were identified, of whom 893,772 (75.9%) were on prior chronic anticoagulation for AF. In patients with COVID-19, being on chronic anticoagulation for AF significantly reduced all-cause mortality (RR 0.75; 95% CI 0.57 to 0.99; p = 0.048; I2 = 89%) and COVID-19-related mortality (RR 0.76; 95% CI 0.72 to 0.79; p < 0.001; I2 = 0%) when compared with no prior anticoagulation. In contrast, there was no difference between groups regarding hospitalization (RR 1.08; 95% CI 0.82 to 1.41; p = 0.587; I2 = 95%) or ICU admission (RR 0.86; 95% CI 0.68 to 1.09; p = 0.216; I2 = 69%).
CONCLUSIONS
In this meta-analysis, chronic anticoagulation for patients with AF who contracted COVID-19 was associated with significantly lower rates of all-cause mortality and COVID-19-related mortality as compared with no previous anticoagulation.

Meta-Analysis
BACKGROUND
Acute pulmonary embolism (PE) is a common cause of death, accounting for 50,000 to 200,000 deaths annually. It is the third most common cause of mortality among the cardiovascular diseases, after coronary artery disease and stroke. The advent of multi-detector computed tomographic pulmonary angiography (CTPA) has allowed better assessment of PE regarding visualisation of the peripheral pulmonary arteries, increasing its rate of diagnosis. More cases of peripheral PEs, such as isolated subsegmental PE (SSPE) and incidental PE, have thereby been identified. These two conditions are usually found in patients with few or none of the classic PE symptoms such as haemoptysis or pleuritic pain, acute dyspnoea or circulatory collapse. However, in patients with reduced cardiopulmonary reserve, classic PE symptoms can be found with isolated SSPEs. Incidental SSPE is found casually in asymptomatic patients, usually by diagnostic imaging performed for other reasons (for example routine CT for cancer staging in oncology patients). Traditionally, all PEs are anticoagulated in a similar manner independent of their location, or number and size of the thrombi. It has been suggested that many patients with SSPE may be treated without benefit, increasing adverse events by a possible unnecessary use of anticoagulants. Patients with isolated SSPE, or incidental PE, may have a more benign clinical presentation compared to those with proximal PEs. However, the clinical significance in patients, and their prognosis, needs to be studied to evaluate whether anticoagulation therapy is required. This is the second update of the Cochrane systematic review published in 2014.
OBJECTIVES
To assess the effectiveness and safety of anticoagulation therapy versus control in patients with isolated subsegmental pulmonary embolism (SSPE) or incidental SSPE.
SEARCH METHODS
The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL and AMED databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 26 November 2019. We also undertook reference checking to identify additional studies.
SELECTION CRITERIA
We included randomised controlled trials of anticoagulation therapy versus control in patients with SSPE or incidental SSPE.
DATA COLLECTION AND ANALYSIS
Two review authors inspected all citations identified to ensure reliable assessment. If relevant studies were identified, we planned for two review authors to independently extract data and to assess the methodological quality of identified trials using the criteria recommended in the Cochrane Handbook for Systematic Reviews of Interventions.
MAIN RESULTS
We did not identify any studies that met the inclusion criteria.
AUTHORS' CONCLUSIONS
There is no evidence from randomised controlled trials to assess the effectiveness and safety of anticoagulation therapy versus control in patients with isolated subsegmental pulmonary embolism (SSPE) or incidental SSPE. Well-conducted research is required before informed practice decisions can be made.

Review
BACKGROUND
Venous thromboembolism (VTE) in pregnancy is an important cause of maternal morbidity and mortality. Low-molecular-weight heparin (LMWH) is the cornerstone of prophylaxis and treatment of thrombotic events during pregnancy. LMWH has fewer adverse effects than other anticoagulants, does not cross the placenta, and is safe for the fetus. However, the use of LMWH during pregnancy is sensitive to womens' underlying preferences. The objective of this review is to systematically assess women's values and preferences research evidence on this topic.
METHODS
We searched four electronic databases from inception to March 2022, and included studies examining values and preferences of using LMWH among pregnant women at risk of VTE. We followed a convergent integrated mixed-methods design to compare and contrast quantitative outcomes (utility and non-utility measures) and qualitative findings. We assessed the certainty of the values and preferences evidence with the GRADE approach for quantitative findings, and with GRADE-CERqual for qualitative evidence. Results were presented in a conjoint display.
RESULTS
We screened 3,393 references and identified seven eligible studies. The mixed methods analysis resulted in four themes. Datasets confirmed each other in that: 1) the majority of women consider that benefits of treatment outweigh the inconveniences of daily injections; and 2) main concerns around medication are safety and injections administration. Quantitative outcomes expanded on the qualitative findings in that: 3) participants who perceived a higher risk of VTE were more willing to take LMWH. Finally, we found a discrepancy between the datasets around: 4) the amount of information preferred to make the decision; however, qualitative data expanded to clarify that women prefer making informed decisions and receive support from their clinician in their decision-making process.
CONCLUSIONS
We are moderately confident that in the context of pregnancy, using LMWH is preferred by women given its net beneficial balance. Integrating data from different sources of evidence, and representing them in a jointly manner helps to identify patient's values and preferences. Our results may inform clinical practice guidelines and support shared decision-making process in the clinical encounter for the management of VTE in the context of pregnancy.

Review
BACKGROUND CONTEXT
Complications such as pressure sores, pulmonary infection, urinary tract infection (UTI), and venous thromboembolism (VTE) are common after spinal cord injury (SCI). These have serious consequences for patients' physical, social, and vocational well-being. Several authoritative organizations have developed guidelines for managing these complications after SCI.
PURPOSE
We aim to systematically review and appraise guidelines on the management of four common complications (pressure sores, pulmonary infection, UTI, and VTE) after SCI as well as to summarize relevant recommendations and assess the quality of their supporting evidence.
DESIGN
Systematic review.
METHODS
We searched Medline, Embase, Cochrane, and Web of Science, as well as guideline-specific databases (eg, National Guideline Clearinghouse) and Google Scholar, from January 2000 to January 2022. We included the most updated guidelines developed by specific authoritative organizations. We evaluated the included guidelines using the Appraisal of Guidelines for Research and Evaluation 2nd edition instrument, which measures six domains (eg, applicability). Recommendations extracted from guidelines were categorized as for, against, or neither for nor against. An evidence assessment was adopted to classify the quality of supporting evidence as poor, fair, or good.
RESULTS
Eleven guidelines from 2005 to 2020 were included, all of which, among the six domains, scored lowest in the domain of applicability. For pressure sores, guidelines recommended for skin inspection, repositioning, and the use of pressure reduction equipment as preventive measures and dressings, debridement, and surgery as treatment measures. For pulmonary infection, guidelines recommended for physical (eg, the use of an insufflation-exsufflation device) and pharmacological measures (eg, the use of bronchodilators). For UTI, guidelines recommended for antibiotics as a treatment measure but recommended against cranberries, methenamine salts, and acidification or alkalinization agents as preventive measures. For VTE prophylaxis, five guidelines recommended for low molecular weight heparin (LMWH). Three guidelines recommended against unfractionated heparin, whereas one guideline recommended for it. Most of the supporting evidence was of poor quality (130/139), and the rest was of fair quality (9/139).
CONCLUSIONS
For pressure sores, pulmonary infection, and UTI, evidence of poor to fair quality indicated consistent recommendations for prevention and treatment measures. For VTE, LMWH was consistently recommended, whereas recommendations on the use of unfractionated heparin were controversial.

Meta-Analysis Review
: Venous thromboembolism (VTE) is common in cancer patients. Anticoagulant therapy with low-molecular-weight heparins (LMWHs) and direct oral anticoagulants (DOACs), such as dalteparin and apixaban, have demonstrated efficacy and safety. However, more comparative research of these drugs is still needed. This study aimed to synthesize evidence on the efficacy of apixaban compared to dalteparin in reducing recurrent VTE, major bleeding, and clinically relevant non-major bleeding associated with cancer. : We systematically searched the PubMed, Scopus, Web of Science, Embase, Cochrane Library, and ClinicalTrials databases up to 5 January 2023, for randomized controlled trials comparing apixaban versus dalteparin as treatment for cancer-associated VTE. Five studies were included. Effects according to meta-analyses were reported as relative risks (RRs) and their 95% confidence intervals (CIs). : It was found that 33 of 734 (4.5%) patients treated with apixaban and 56 of 767 (7.3%) with dalteparin had recurrent VTE as the efficacy outcome (RR 0.49, 95% CI 0.15-1.58, I 38%). Major bleeding occurred in 25 of 734 patients treated with apixaban (3.4%) and 27 of 767 with dalteparin (3.5%) (RR 1.29, 95% CI 0.31-5.27, I 59%). Likewise, clinically relevant non-major bleeding occurred in 64 of 734 patients treated with apixaban (8.7%) and 46 of 767 (5.9%) with dalteparin (RR 1.52, 95% CI 1.05-2.19, I 0%). : Apixaban showed a lower risk of recurrent VTE than dalteparin in patients with cancer-associated VTE, albeit with no statistical difference. Statistical significance was observed for no major clinically relevant bleeding but not for major bleeding.
