Meta-Analysis
BACKGROUND
Data on complications after upper extremity vein thrombosis (UEVT) are limited and heterogeneous.
METHODS
The aim of the present study was to evaluate the pooled proportions of venous thromboembolism (VTE) recurrence, bleeding, and post-thrombotic syndrome (PTS) in patients with UEVT. A systematic literature review was conducted of PubMed, Embase, and the Cochrane Library databases from January 2000 to April 2023 in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. All studies included patients with UEVT and were published in English. Meta-analyses of VTE recurrence, bleeding, and of PTS after UEVT were performed to compute pooled estimates and associated 95% confidence intervals (CIs). Subgroup analyses of cancer-associated UEVT and catheter-associated venous thrombosis were conducted. Patients with Paget-Schroetter syndrome or effort thrombosis were excluded.
RESULTS
A total of 55 studies with 15,694 patients were included. The pooled proportions for VTE recurrence, major bleeding, and PTS were 4.8% (95% CI, 3.8%-6.2%), 3.0% (95% CI, 2.2%-4.0%), and 23.8% (95% CI, 17.0%-32.3%), respectively. The pooled proportion of VTE recurrence was 2.7% (95% CI, 1.6%-4.6%) for patients treated with direct oral anticoagulants (DOACs), 1.7% (95% CI, 0.8%-3.7%) for patients treated with low-molecular-weight heparin (LMWH), and 4.4% (95% CI, 1.5%-11.8%) for vitamin K antagonists (VKAs; P = .36). The pooled proportion was 6.3% (95% CI, 4.3%-9.1%) for cancer patients compared with 3.1% (95% CI, 2.1%-4.6%) for patients without cancer (P = .01). The pooled proportion of major bleeding for patients treated with DOACs, LMWH, and VKAs, was 2.1% (95% CI, 0.9%-5.1%), 3.2% (95% CI, 1.4%-7.2%), and 3.4% (95% CI, 1.4%-8.4%), respectively (P = .72). The pooled proportion of PTS for patients treated with DOACs, LMWH, and VKAs was 11.8% (95% CI, 6.5%-20.6%), 27.9% (95% CI, 20.9%-36.2%), and 24.5% (95% CI, 17.6%-33.1%), respectively (P = .02).
CONCLUSIONS
The results from this study suggest that UEVT is associated with significant rates of PTS and VTE recurrence. Treatment with DOACs might be associated with lower PTS rates than treatment with other anticoagulants.

Review
INTRODUCTION
Hemoptysis is one of the most common symptoms of respiratory system diseases. Common causes include bronchiectasis, tumors, tuberculosis, aspergilloma, and cystic fibrosis. The severity of hemoptysis varies from mild to moderate to massive hemoptysis and can easily lead to hemodynamic instability and death from suffocation or shock. Nevertheless, the most threatening hemoptysis that is presented to the emergency department and requires hospitalization is the massive one. In these cases, today, the most common way to manage hemoptysis is bronchial artery embolization (BAE).
METHODS
A systematic literature search was conducted in PubMed and Scopus from January 2017 (with the aim of selecting the newest possible reports in the literature) until May 2023 for studies reporting massive hemoptysis. All studies that included technical and clinical success rates of hemoptysis management, as well as rebleeding and mortality rates, were included. A proportional meta-analysis was conducted using a random-effects model.
RESULTS
Of the 30 studies included in this systematic review, 26 used bronchial artery embolization as a means of treating hemoptysis, with very high levels of both technical and clinical success (greater than 73.7% and 84.2%, respectively). However, in cases where it was not possible to use bronchial artery embolization, alternative methods were used, such as dual-vessel intervention (80% technical success rate and 66.7% clinical success rate), customized endobronchial silicone blockers (92.3% technical success rate and 92.3% clinical success rate), antifibrinolytic agents (50% clinical success rate), and percutaneous transthoracic embolization (93.1% technical success rate and 88.9% clinical success rate), which all had high success rates apart from antifibrinolytic agents. Of the 2467 patients included in these studies, 341 experienced rebleeding during the follow-up period, while 354 other complications occurred, including chest discomfort, fever, dysphagia, and paresis. A total of 89 patients died after an episode of massive hemoptysis or during the follow-up period. The results of the meta-analysis showed a pooled technical success of bronchial artery embolization equal to 97.22% and a pooled clinical success equal to 92.46%. The pooled recurrence was calculated to be 21.46%, while the mortality was 3.5%. These results confirm the ability of bronchial artery embolization in the treatment of massive hemoptysis but also emphasize the high rate of recurrence following the intervention, as well as the risk of death.
CONCLUSION
In conclusion, massive hemoptysis can be treated with great clinical and technical success using bronchial artery embolization, reducing mortality. Mortality has now been reduced to a small percentage of cases.

Meta-Analysis
INTRODUCTION
Gastrointestinal bleeding results in significant morbidity, cost and mortality. TXA, an antifibrinolytic agent, has been proposed to reduce mortality; however, many studies report conflicting results.
METHODS
The aim of the study was to perform the first systematic review and meta-analysis of RCTs to evaluate the efficacy TXA for both upper and lower gastrointestinal bleeding. This was performed per PRISMA guidelines. PubMed, EMBASE, Cochrane and Scopus databases were searched for RCTs. Dichotomous variables were pooled as risk ratios (RR) with 95% confidence intervals (CI) using the MH method with random effects modelling.
RESULTS
Fourteen RCTs were identified with 14,338 patients and mean age of 58.4 years. 34.9% (n = 5008) were female and 65.1% (n = 9330) male. There was no significant difference in mortality between TXA and placebo (RR 0.86 95% CI (0.74 to 1.00), P: 0.05). The secondary outcomes, similarly, did not yield significant results. These included rebleeding, need for surgical intervention (RR: 0.75 95% CI (0.53, 1.07)), endoscopic intervention (RR: 0.92 95% CI (0.70, 1.22)), transfusion requirement (RR: 1.01 95% CI (0.94, 10.7)) and length of stay (RR: 0.03 95% CI (- 0.03, 0.08)). There was no increased risk of VTE, RR: 1.29 95% CI (0.53, 3.16). One trial (n = 12,009) reported an increased risk of seizure in the TXA group, RR: 1.73 95% CI (1.03-2.93).
CONCLUSION
TXA does not reduce mortality in patients with acute upper or lower gastrointestinal bleeding and may confer an increased risk of seizures. The authors do not recommend the use of TXA in acute gastrointestinal bleeding.

Review
Cataract, defined as the opacification of the lens that prevents clear vision, is a leading cause of vision loss and impairment worldwide. Elderly people comprise the highest proportion of those suffering from this eye disease. According to the National Institute of Health (NIH), the risk of developing aged-related cataract (ARC) increases with every decade of life, starting from the age of 40. Despite progress in surgical treatment methods, life-style modifications may be beneficial in prevention or slowing down the progression of ARC. This systematic review aims to summarize studies on the significance of specific nutritional patterns, dietary products, vitamins, minerals, and carotenoids intake in the onset or progression of ARC. In this context, the presented paper thoroughly analyzes 24 articles, following the PRISMA guidelines. The results indicate significant protective effects of various dietary patterns, including the Korean balanced diet, vegetarian diet, "dairy products and vegetables", "traditional", "antioxidant", and "omega-3" patterns. Additionally, the consumption of fruits, vegetables, legumes, nuts, skimmed yoghurt, fish, coffee, and vitamins has shown positive effects on cataract incidence. Therefore, further research seems to be essential to gain a better understanding of these associations and to create uniform dietary recommendations for both the vulnerable population and ARC patients.

Meta-Analysis Review
Tranexamic acid is an antifibrinolytic drug that is widely used during surgery, but there are concerns about its thromboembolic effects. We aimed to investigate the effect of prophylactic intravenous tranexamic acid on thromboembolic outcomes in patients undergoing non-cardiac surgery. The MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials were searched. Randomised controlled trials comparing intravenous tranexamic acid with placebo or no treatment in patients undergoing non-cardiac surgery were included. The primary outcome was a composite of peri-operative cardiovascular thromboembolic events, defined as any deep vein thrombosis, pulmonary embolism, myocardial ischaemia/infarction or cerebral ischaemia/infarction. A total of 191 randomised controlled trials (40,621 patients) were included in the review. The primary outcome occurred in 4.5% of patients receiving intravenous tranexamic acid compared with 4.9% of patients in the control group. Our analysis showed that there was no difference between groups for composite cardiovascular thromboembolic events (risk ratio 1.02, 95%CI 0.94-1.11, p = 0.65, I 0%, n = 37,512). This finding remained robust when sensitivity analysis was performed with continuity correction and in studies with a low risk of bias. However, in trial sequential analysis, our meta-analysis only achieved 64.6% of the required information size. There was no association between intravenous tranexamic acid and seizure rate or mortality rate within 30 days. Intravenous tranexamic acid was associated with a reduced blood transfusion rate compared with control (9.9% vs. 19.4%, risk ratio 0.46, 95%CI 0.41-0.51, p < 0.0001). It was encouraging to see the evidence that the administration of intravenous tranexamic in patients undergoing non-cardiac surgery was not associated with an increased risk of thromboembolic outcomes. However, our trial sequential analysis demonstrated that currently available evidence is not yet sufficient to reach a firm conclusion.

Meta-Analysis
INTRODUCTION
Tranexamic acid (TXA) has been widely utilized to reduce blood loss and allogeneic transfusions in patients who undergo lower limb arthroplasty. In recent years, there have been several articles reporting the incidence of periprosthetic joint infection (PJI) as a primary outcome of TXA administration, but no meta-analysis has been conducted to date. The present systematic review and meta-analysis evaluated the efficacy of TXA administration in preventing PJI and surgical site infection (SSI).
MATERIALS AND METHODS
Pubmed, CINAHL, and the Cochrane Library bibliographic databases were searched for studies published by May 24, 2022, that evaluated the effects of TXA on PJI and SSI. Two researchers screened the identified studies based on the PRISMA flow diagram. The quality of each randomized clinical trial was assessed using Version 2 of the Cochrane risk-of-bias tool for randomized trials (ROB2.0), and the quality of cohort and case-control studies was assessed by risk of bias for nonrandomized studies (ROBANS-I).
RESULTS
Of the 2259 articles identified from the database search, 31 were screened and selected. Treatment with TXA significantly reduced the incidence of overall infection, including PJI, SSI, and other infections (OR 0.55; 95% CI 0.49-0.62) (P < 0.00001), and that of PJI alone (OR 0.53; 95% CI 0.47-0.59) (P < 0.00001). TXA reduced the incidence of overall infection in patients who underwent total hip arthroplasty (THA; OR 0.51; 95% CI: 0.35-0.75) (P = 0.0005) and total knee arthroplasty (TKA; OR 0.55; 95% CI: 0.43-0.71) (P < 0.00001). Intravenous administration of TXA reduced the incidence of overall infection (OR 0.59; 95% CI 0.47-0.75) (P < 0.0001), whereas topical administration did not.
CONCLUSIONS
Intravenous administration of TXA reduces the incidence of overall infection in patients undergoing both THA and TKA.

Meta-Analysis
Postpartum hemorrhage (PPH) is the leading cause of maternal mortality worldwide and PPH resulting in transfusion is the most common maternal morbidity in the United States. Literature demonstrates that tranexamic acid (TXA) can reduce blood loss in cesarean deliveries; however, there is little consensus on the impact on major morbidities like PPH and transfusions. We conducted a systematic review/meta-analysis of randomized controlled trials (RCTs) to evaluate if administration of prophylactic intravenous (IV) TXA prevents PPH and/or transfusions following low-risk cesarean delivery. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines were followed. Five databases were searched: Cochrane, EBSCO, Ovid, PubMed, and ClinicalKey. RCTs published in English between January 2000 and December 2021 were included. Studies compared PPH and transfusions in cesarean deliveries between prophylactic IV TXA and control (placebo or no placebo). The primary outcome was PPH, and the secondary outcome was transfusions. Random effects models were used to calculate effect size (ES) of exposure in Mantel-Haenszel risk ratios (RR). All analysis was done at a confidence level (CI) of = 0.5. Modeling showed that TXA led to significantly less risk of PPH than control (RR: 0.43; 95% CI: 0.28-0.67). The effect on transfusion was comparable (RR: 0.39; 95% CI: 0.21-0.73). Heterogeneity was minimal ( = 0%). Due to the large sample sizes needed, many RCTs are not powered to interpret TXA's effect on PPH and transfusions. Pooling these studies in a meta-analysis allows for more power and analysis but is limited by the heterogeneity of studies. Our results minimize heterogeneity while demonstrating that prophylactic TXA can lower PPH occurrence and reduce the need for blood transfusion. We suggest considering prophylactic IV TXA as the standard of care in low-risk cesarean deliveries. KEY POINTS: · Consider TXA prior to incision for singleton, term pregnancies undergoing elective cesarean.. · Prophylactic TXA is effective in preventing PPH and blood transfusions.. · Routine use of TXA has the potential to decrease transfusion-related complications and costs..

Meta-Analysis Review
OBJECTIVE
Endoscopic sinus surgery (ESS) and endoscopic skull base surgery (ESBS) approaches have revolutionized the management of sinonasal and intracranial pathology. Maintaining surgical hemostasis is essential as bleeding can obscure the visibility of the surgical field, thus increasing surgical duration, risk of complications, and procedural failure. Tranexamic acid (TXA) acts to reduce bleeding by inhibiting fibrin degradation. This review aims to assess whether TXA improves surgical field quality and reduces intraoperative blood loss compared with control.
METHODS
We searched PubMed, MEDLINE, Embase, Web of Science, and Cochrane Library from inception until September 1, 2022. Two reviewers independently screened citations, extracted data, and assessed methodological quality using the Cochrane risk-of-bias tool for randomized trials. Data were pooled using a random-effect model, with continuous data presented as mean differences and dichotomous data presented as odds ratios.
RESULTS
Seventeen ESS randomized controlled trials (n = 1377) and one ESBS randomized controlled trial (n = 50) were reviewed. Significant improvement in surgical field quality was achieved with both systemic TXA (six studies, p < 0.00001) and topical TXA (six studies, p = 0.01) compared with the control. Systemic TXA (eight studies) and topical TXA (three studies) both achieved a significant reduction in intraoperative blood loss compared with the control (p < 0.00001). There were significant differences in operative times (p < 0.001) but no significant difference in perioperative outcomes (p = 0.30).
CONCLUSION
This meta-analysis demonstrated that the administration of TXA in ESS can improve surgical field quality and reduce intraoperative blood loss. TXA use did not result in increased perioperative complications including thrombotic events.

Meta-Analysis Review
BACKGROUND
The effect of tranexamic acid (TXA) has been proven to be effective in reducing blood loss in lower limb arthroplasty. The aim of this study is to investigate the effect of TXA in shoulder surgery with the updated studies.
MATERIALS AND METHODS
A systematic review and meta-analysis of all the randomized controlled trials were conducted. We compared the outcomes of patients with and without TXA. The PubMed, MEDLINE, EMBASE, and CENTRAL databases were systematically searched for relevant studies.
RESULTS
A total of 14 studies, enrolling 1131 patients, were included for qualitative and quantitative analysis. Our results revealed that TXA was associated with a significant reduction in total volume blood loss (mean difference [MD]: -112.97, P = .0006), drain output (MD: -81.90, P < .00001), hemoglobin changes (MD: -0.55, P = .02), shorter operative time (MD: -6.19, P = .01), and lower risk of hematoma formation (odds ratio: -0.20, P = .01). The postoperative visual analog scale pain score was also significantly better in the TXA group (MD: -0.78, P < .00001). No significant difference was detected in length of hospital stay and incidence of thromboembolization.
CONCLUSION
The usage of TXA in shoulder surgery appeared to be safe and effective in reducing blood loss without any significant complication.

Meta-Analysis Review
This meta-analysis aimed to assess whether administration tranexamic acid (TXA) could reduce blood loss and vascular events in patients undergoing unicompartmental knee arthroplasty (UKA). We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and case control trials (CCT) that compared outcomes of patients who did and did not receive TXA during UKA. We searched Cochrane Central Register of including PubMed, EMBASE, Web of Science, the Cochrane Library, Wan Fang data, CBM and CNKI for relevant studies. We assessed the risk of bias of the included studies and calculated pooled risk estimates. The primary outcome was operation time, intraoperative blood loss, postoperative HCT, postoperative HB, transfusion rate, dominant blood loss, postoperative drainage volume, hidden blood loss, total blood loss, postoperative ROM,postoperative VAS score, postoperative complications. Data were using fixed-effects or random-effects models with standard mean differences and risk ratios for continuous and dichotomous variables, respectively. Finally, 9 clinical studies with 744 patients were included in this meta-analysis. Compared with the control group, TXA group could reduced transfusion rate, dominant blood loss, postoperative drainage volume, hidden blood loss, and total blood loss, and increased postoperative HB with statistically significance. The main findings of this meta-analysis are that the transfusion rate, dominant blood loss, postoperative drainage volume, hidden blood loss, total blood loss and postoperative HB in the tranexamic acid group were superior to those in the routine group. Additional high-quality RCTs should be conducted in the future.
