JACC. Advances Sep 2023Data on the association between atrial fibrillation (AF) and venous thromboembolism (VTE) are controversial.
BACKGROUND
Data on the association between atrial fibrillation (AF) and venous thromboembolism (VTE) are controversial.
OBJECTIVES
The purpose of this study was to investigate the risk of VTE in patients with AF according to the time from AF diagnosis.
METHODS
Systematic review of MEDLINE (PubMed), Embase, Cumulative Index to Nursing and Allied Health Literature (EBSCO host), Cochrane Central Register of Controlled Trials (2020) in the Cochrane Library, and World Health Organization Global Index Medicus databases and meta-analysis of observational studies. The risk of VTE, deep vein thrombosis (DVT) and pulmonary embolism (PE) was analyzed according to the time of AF onset: 1) short (≤3 months); 2) medium (≤6 months); and 3) long (>6 months) time groups.
RESULTS
Eight studies were included with 4,170,027 patients, of whom 650,828 with AF. In the short-term group, AF was associated with the highest risk of either PE (HR: 9.62; 95% CI: 7.07-13.09; I = 0%) or DVT (HR: 6.18; 95% CI: 4.51-8.49, I = 0%). Even if to a lesser extent, AF was associated with a higher risk of VTE (HR: 3.69; 95% CI: 1.65-8.27; I = 79%), DVT (HR: 1.75; 95% CI: 1.43-2.14; I = 0%), and PE (HR: 4.3; 95% CI: 1.61-11.47; I = 68%) in the up to 6 months and long-term risk group >6 months groups (HR: 1.39; 95% CI: 1.00-1.92; I = 72%) and PE (HR: 1.08; 95% CI: 1.00-1.16; I = 0%).
CONCLUSIONS
The risk of VTE is highest in the first 3 to 6 months after AF diagnosis and decreases over time. The early initiation of anticoagulation in patients with AF may reduce the risk of VTE.

Meta-Analysis
We sought to assess the efficacy and safety of endovenous laser ablation utilizing a 980 nm device versus a 1470 nm device in the treatment of lower limb venous insufficiency. We performed a systematic review adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 statement. A research on PubMed, Scopus and Web of science for articles published by January 2024 was conducted. The primary endpoint was great saphenous vein (GSV) and truncal vein occlusion. Eleven studies encompassing 3061 patients and 3193 truncal veins, were included. The 1470 nm device demonstrated superior truncal vein and GSV occlusion outcomes compared to the 980 nm device at the early, one-year, and medium to long-term follow-up intervals. Odds ratios (OR) were 2.79(95%CI:1.31-5.94), 2.22(95%CI:1.21-4.07), and 2.02(95%CI:1.24-3.29) for truncal veins and 2.54(95%CI:1.119-5.41), 2.06(95%CI:1.07-3.95) and 2.04(95%CI:1.25-3.33) for GSV, across the respective intervals. While both devices demonstrated minimal, deep vein thrombosis (DVT), endovenous heat-induced thrombosis (EHIT) ≥ 2, and burn estimates, the 1470 nm device exhibited improved paresthesia, risk ratio (RR), 0.51(95%CI:0.34-0.77) and pain outcomes, standardized mean difference (SMD), -0.62(95%CI:-0.99to-0.25). Subgroup analysis displayed enhanced occlusion outcomes with the 1470 nm device for the six-month and one-year intervals, irrespective of fiber type. Radial fibers were associated with improved paresthesia outcomes (β=-0.9520,p = 0.03). This review emphasized the enhanced efficacy of the 1470 nm device over the 980 nm device, regardless of fiber type. Radial fibers showed promise for improved paresthesia outcomes, suggesting similar safety profiles for both systems. Conclusive remarks on pain outcomes were impeded by data limitations.

BACKGROUND
We conducted an overview to assess immune adverse effects associated with the COVID-19 vaccine, guiding safer choices and providing evidence-based information to clinicians.
METHODS
Forty-three studies on adverse effects of vaccines were reviewed from PubMed, Embase, and Web of Science. Single-arm meta-analyses estimated summary effects, incidence, presentation, etc. An overview using single-arm meta-analysis and reported the findings following the guidelines outlined in the 'Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) specifically focusing on myocarditis and thrombosis. After screening 2,591 articles, 42 studies met the inclusion criteria. Methodological quality was evaluated using AMSTAR 2. Disagreements were resolved via consensus. Data analysis utilized a random-effects model in R software to estimate incidence rates of selected adverse events.
RESULTS
After removing 1,198 duplicates and screening out irrelevant articles from a total of 2,591, we included 42 studies. Adverse reactions to vaccinations include myocarditis, thrombosis, skin reactions, GBS, etc. thrombosis and myocarditis are the most dangerous diseases associated with vaccination. Myocarditis occurred in 6% of Vector vaccine recipients, compared to 61% of mRNA vaccine recipients. Thrombosis was more common after Vector vaccination (91%) than after mRNA vaccination (9%). Furthermore, eight studies conducted anti-PF4 antibody tests and yielded a positivity rate of 67%. Meta-analysis showed that among all patients with Vaccine-induced Thrombotic Thrombocytopenia, cerebral venous sinus thrombosis occurred in 66%, and intracranial hemorrhage occurred in 43%. The rates of deep vein thrombosis and pulmonary thromboembolism in vaccinated patients were 13% and 23%, respectively, with a pooled case fatality rate of 30%.
CONCLUSION
The results of this overview indicate the majority of adverse reactions are self-limiting and require minimal intervention, while rare occurrences such as myocarditis and thrombosis pose a potentially fatal threat.

Review
BACKGROUND
Peripherally inserted central catheters (PICCs) and midline catheters (MCs) may offer convenient intravenous access, but evidence to support their place in palliative care is limited. This review aimed to assess catheter indications, utilization, complications, dwell time, and patient experiences in cancer patients receiving palliative care.
METHODS
A systematic search for studies on catheter utilization for supportive or symptom treatment was conducted in Medline, Embase, CINAHL, Web of Science, Cochrane, and CENTRAL databases. Studies with a study population or a subgroup of palliative care cancer patients were included. Study quality was assessed using the Effective Public Health Practice Quality assessment tool.
RESULTS
Of 7631 unique titles, 17 articles were examined in detail, all published between 2002 and 2022. Median catheter dwell time varied from 15 to 194 days, the longest when utilized for home parenteral nutrition. For pain and symptom management, the typical duration was 2-4 weeks, often until the patient's death. Complication rates were minimal, with thrombosis, infections, and occlusion ranging from 0 to 2.46 incidents per 1000 catheter days. In studies from palliative care services, patients reported minimal distress during procedures and high user satisfaction. Quality of life assessments post-procedure improved, possibly influenced by concurrent specialist palliative care provision. All studies were assessed to be of moderate or weak quality.
CONCLUSION
PICC and MC are safe and valuable tools in palliative care cancer patients who would benefit from intravenous access for symptom management. Further studies are needed to clarify indications for PICC or MC in palliative care.

Review
PURPOSE
To estimate the prevalence of peripherally inserted central catheter (PICC)-related venous thrombosis in patients with hematological malignancies.
METHODS
A systematic review of observational studies that evaluated the occurrence of PICC-related venous thrombosis in children, adults, and older people with hematological malignancies was conducted. Searches were carried out on June 12th, 2023 on PubMed, CINAHL, Embase, Web of Science Core Collection, Scopus, and LILACS, and to gray literature on Google Scholar, and ProQuest Dissertations and Theses Global. Eligibility criteria were applied independently by two reviewers, first on the titles and abstracts on the Rayyan platform and then on the full text of eligible studies. Risk of bias was assessed by the JBI checklist. Data were summarized descriptively, and the meta-analysis was carried out using the MetaXL 5.3 software. The review followed JBI guidelines and PRISMA for reporting.
RESULTS
In the 40 studies included, prevalence of PICC-related venous thrombosis was 9% in general, 9% in adults, and 6% in children with hematological malignancies. Most studies only evaluated cases of symptomatic thrombosis (n = 25; 64%).
CONCLUSION
Patients with hematological malignancies using PICC have an estimated prevalence of PICC-related venous thrombosis of 9%, and this rate may be underestimated due to the consideration of mostly symptomatic cases.

Review
Adolescent venous thromboembolism (VTE) has unique challenges in management, complications, and compliance to anticoagulants. Direct oral anticoagulants (DOACs) have been approved for pediatric VTE management, with an increasing use especially in adolescents. Primary objective is to evaluate the safety and efficacy of DOAC therapy in adolescent VTE. Secondary objectives include adverse events, bleeding events, and overall mortality. A SR protocol was registered in PROSPERO 2022 (CRD42022363928). Databases were searched from inception to September 22, 2022. Studies with children aged 10-18 years, VTE diagnosis, DOAC therapy, randomized control trials (RCTs), cohort, and relevant study types were included. Studies including prophylaxis, non-DOAC therapy, arterial thrombosis, age outliers, non-relevant study types were excluded. Findings are reported in accordance to PRISMA 2020. Nine reports from five studies, published between 2016 and 2022, were included. Rivaroxaban was the most common DOAC. VTE recurrence was 0.02% in the rivaroxaban phase III trial and one patient in the dabigatran phase IIb/III trial. Complete/partial thrombus resolution (CR/PR) was 76.6% in the rivaroxaban phase III trial, and 83.9% in the dabigatran phase IIb/III trial. CR/PR was found to be 68.4% in Dhaliwal et al. study and 83.3% in Hassan et al. study. Major bleeding occurred in one patient. Headache and gastrointestinal symptoms were commonly seen. All-cause mortality occurred in a patient due to cancer progression. DOAC therapy in adolescent VTE had CR/PR in two-thirds of the patients, with low incidence of VTE recurrence and major bleeding. As there are only two randomized controlled trial (RCTs), future adolescents' studies are required to validate our results.

Meta-Analysis
BACKGROUND
Budd-Chiari syndrome (BCS) results from the obstruction of the hepatic venous flow, usually at the level of the hepatic vein or inferior vena cava. When left untreated, it can progress with several complications, including liver cirrhosis. Transjugular intrahepatic portosystemic shunt (TIPS) appears to be effective in a subgroup of BCS patients.
OBJECTIVE
To perform a systematic review and meta-analysis of TIPS effectiveness in BCS treatment, considering the survival rate, reduction in portosystemic pressure, need for liver transplantation, technical failure, and shunt dysfunction for up to 10 years of follow-up.
METHODS
We evaluated 17 studies published in PubMed, Science Direct, Web of Science, and SCOPUS databases, which used TIPS as a treatment for BCS, comprising 618 subjects between 18 and 78 years old. We assessed the bias risk by the NOS, NHI, and JBI scales for cohort stu-dies, before-after studies, and case series, respectively. We conducted the meta-analyses by extracting the number of events and the total patients evaluated to perform the proportion meta-analyses using the R software ("meta" package - version 4.9-6).
RESULTS
The pooled results (95%CI) showed a 19% (25.9-12.5%) rate of portosystemic pressure reduction, 6% (1-12%) rate for the need for liver transplants despite the use of TIPS, 2% (1-6%) technical failure rate, 30% (18-46%) shunt dysfunction rate, and 88% (81-93%) for the mean frequency of patients alive between 1 and 10 years after the procedure. We stratified survival rate and found an 86% (74-93%) prevalence of living subjects during less than five years, 92% (83-97%) at five years, and a 77% frequency (68-83%) of patients alive ten years after the TIPS placement.
CONCLUSION
TIPS is an effective treatment for BCS, providing a high 10-year frequency of living patients and a significant decrease in portosystemic pressure. The need for liver transplants after TIPS and the technical failure rate is low.

Review
May-Thurner syndrome (MTS) is an anatomical condition of external luminal compression of common iliac vein due to a partial obstruction of the common iliac vein between common iliac artery and lumbar vertebra causes deep-vein thrombosis, venous hypertension, and chronic venous insufficiencies. In this article, we review present evidence of the clinical diagnosis and management of MTS. Here, we conducted a literature review of studies on MTS. We also reviewed different clinical features, presentation, diagnostic methods, and therapeutic procedure for this condition. Most studies mentioned the diagnosis of this condition is performed by color Doppler, computed tomographic angiography, venography, and problem-solving cases by intravascular ultrasound technique. Nonsurgical methods of management are first line, and vascular surgery is reserved for refractory cases. Multiple modalities are required to reach the diagnosis of MTS, and noninvasive intervention radiology methods are the first line of management. This review highlights the presentations of MTS and outlines diagnostic procedure and management.

BACKGROUND
Post-thrombotic syndrome (PTS) is common in patients with deep vein thrombosis (DVT). It is unclear if different types of anticoagulant therapies (e.g. vitamin K antagonists (VKA), direct oral anticoagulants (DOACs) or low molecular weight heparin (LMWH)) are associated with different risks of PTS. We sought to assess the incidence rates of PTS development following a proximal DVT of the lower extremity managed with different types of anticoagulation regimens.
METHODS
A systematic search of MEDLINE, EMBASE and PubMed, from inception to June 2023 was performed. The primary outcome was development of PTS. The secondary outcomes included severe PTS, venous ulcers, and major bleeding. Incidence rates were pooled using the random effects model and expressed as event per 100 patient-years with its associated 95 % confidence intervals (CI) using R software.
RESULTS
A total of 21 (4342 patients) articles were included in the analysis. The adjusted pooled incidence of PTS was 15.1 (95 % CI: 8.7 to 26.1), 18.2 (95 % CI: 9.4 to 35.1) and 24.6 (95 % CI: 9.2 to 65.5) per 100 patient-years patients managed with VKA, DOAC and LMWH, respectively. The adjusted pooled incidence of severe PTS was 5.1 (95 % CI: 2.6 to 10.0) and 0.2 (95 % CI: 0.01 to 2.7) per 100 patient-years for VKAs and DOACs, respectively.
CONCLUSIONS
The development of PTS is common in patients with proximal lower extremity DVT. The incidence rates of PTS seem to be similar across the different anticoagulation regimens, but severe PTS may be lower among patients receiving a DOAC.
