Meta-Analysis Review
Since the 1950 s, several studies have reported that patients using first generation and/or second-generation antipsychotics had increased risk of venous thromboembolism events. These events include deep vein thrombosis and/or pulmonary embolism (PE). However, data about fatal PE in patients on antipsychotics (APs) remain scarce. Thus, the current study aimed to investigate sociodemographic, clinical and pharmacological characteristics related to psychiatric patients on APs and who died from a fatal PE. We reported a case-series, then conducted a literature review of relevant studies and performed a meta-analysis of studies with usable data. The main outcome of the study suggested a significantly high risk of fatal PE in patients using APs compared to nonusers (Odds Ratio=6.68, with 95% confidence interval 1.43-31.11). Clozapine was the most incriminated drug. Low potency first generation APs were the second most exhibited medication. Studies about the topic remain scarce with a high heterogeneity and a high probability of bias. Further studies are needed to ascertain this risk and to establish target preventive measures in this particularly vulnerable population.

PURPOSE
Pulmonary vein isolation (PVI) through catheter ablation is the basis for the treatment of atrial fibrillation (AF). The left common ostium (LCO) is a high prevalence anatomical variation and has conflicting results in the effects on the prognosis following ablation. We undertook a systematic review and meta-analysis of studies that compared the arrhythmia recurrence rate after radiofrequency ablation or cryoablation balloon between patients with normal pattern pulmonary vein and patients with LCO.
METHODS AND RESULTS
Results were pooled using a fixed or random effect, at the discretion of heterogeneity (>25%), in addition, we associated subgroup analysis in these cases and when clinically indicated. Fourteen non-randomized studies totaling 3278 patients were included. In analyses using the two energies all patients: OR 1.01 (95% CI 0.84-1.23; = .90, = 67%) and excluding patients with any type of persistent AF (PeAF) and those submitted to linear atrial lesion (LAL) OR 0.80 (95% CI 0.52-1.22; = .30, = 71%). Using CRYO: all patients OR 1.34 (95% CI 1.03-1.74; = .03, = 0%). Using RF: all patients-OR 0.55 (95% CI 0.32-0.95; = .03, = 49%); excluding studies with long duration PeAF and the performance of LAL concomitant-OR 0.45 (95% CI 0.23-0.91; = .03, = 44%).
CONCLUSION
The results suggest a better prognosis in patients with LCO, submitted to PVI without additional LAL under RF energy in paroxysmal AF and short-duration PeAF. In patients undergoing CRYO, the presence of LCO suggests a worse prognosis.

BACKGROUND
Peripherally inserted central catheters (PICCs) and midlines are commonly used devices for reliable vascular access. Infection and thrombosis are the main adverse effects of these catheters. We aimed to evaluate the relative risk of complications from midlines and PICCs.
METHODS
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies. The primary outcomes were catheter-related bloodstream infection (CRBSI) and thrombosis. Secondary outcomes evaluated included mortality, failure to complete therapy, catheter occlusion, phlebitis, and catheter fracture. The certainty of evidence was assessed using the GRADE approach.
RESULTS
Of 8368 citations identified, 20 studies met the eligibility criteria, including 1 RCT and 19 observational studies. Midline use was associated with fewer patients with CRBSI compared with PICCs (odds ratio [OR], 0.24; 95% CI, 0.15-0.38). This association was not observed when we evaluated risk per catheter. No significant association was found between catheters when evaluating risk of localized thrombosis and pulmonary embolism. A subgroup analysis based on location of thrombosis showed higher rates of superficial venous thrombosis in patients using midlines (OR, 2.30; 95% CI, 1.48-3.57). We did not identify any significant difference between midlines and PICCs for the secondary outcomes.
CONCLUSIONS
Our findings suggest that patients who use midlines might experience fewer CRBSIs than those who use PICCs. However, the use of midline catheters was associated with greater risk of superficial vein thrombosis. These findings can help guide future cost-benefit analyses and direct comparative RCTs to further characterize the efficacy and risks of PICCs vs midline catheters.

Meta-Analysis
PURPOSE
The purpose of this systematic review and meta-analysis was to evaluate the feasibility and safety of a same-day discharge protocol following pulmonary vein isolation (PVI).
METHODS
PubMed and Embase were systematically investigated from the inception to 20 July 2020. Studies on safety and feasibility of PVI for atrial fibrillation (AF) were included. Study-specific estimates were combined using one-group meta-analysis with a random-effects model.
RESULTS
Seven observational studies investigating the safety and feasibility of same-day discharge protocols were identified. Of a total of 3656 patients who have undergone PVI for AF, the overall complication rate was 0.80% (95% confidence interval [CI], 0.20-1.40%). The readmission within 30-day following same-day discharge protocol occurred at a pooled rate of 3.6% (95% CI, 0.0-8.4%). Frequent complications following the procedure were complications related to vascular access (0.38%; 95% CI, 0.18-0.58%), and phrenic nerve injury (0.19%; 95% CI, 0.05-0.33%). The reported complications in SDD group were mainly based on results among patients without perioperative complications.
CONCLUSIONS
The introduction of same-day discharge strategies might be safe and feasible in selected patients given the reported complication and re-admission rates in the current practice. Further prospective studies are needed to confirm these findings.

Meta-Analysis Review
BACKGROUND
Although concomitant pulmonary vein isolation (PVI) is used more frequently than the Cox-Maze procedure, which is currently the gold standard treatment for atrial fibrillation (AF), data on the comparative effectiveness of the two procedures after concomitant mitral valve (MV) surgery are still limited.
OBJECTIVE
We conducted a systematic review to identify randomized controlled trials (RCTs) and observational studies comparing the mid-term mortality and recurrence of AF after concomitant Cox-Maze and PVI in patients with AF undergoing MV surgery based on 12-month follow-up.
METHODS
Medline, EMBASE databases, and the Cochrane Library were searched from 1987 up to March 2022 for studies comparing concomitant Cox-Maze and PVI. Additionally, a meta-analysis of RCTs was performed to compare the mid-term clinical outcomes between these two surgical ablation techniques.
RESULTS
Three RCTs and three observational studies meeting the inclusion criteria were included in this systematic review with 790 patients in total (532 concomitant Cox-Maze and 258 PVI during MV surgery). Most studies reported that the concomitant Cox-Maze procedure was associated with higher freedom from AF at 12-month follow-up than PVI. Regarding AF recurrence, estimates pooled across the three RCTs indicated large heterogeneity and high uncertainty. In the largest and highest quality RCT, 12-month AF recurrence was higher in the PVI arm (risk ratio = 1.58, 95% CI: 0.91-2.73). In two out of three higher-quality observational studies, 12-month AF recurrence was higher in PVI than in the Cox-Maze arm (estimated adjusted probabilities 11% vs. 8% and 35% vs. 17%, respectively). RCTs demonstrated comparable 12-month mortality between concomitant Cox-Maze and PVI, while observational studies demonstrated the survival benefit of Cox-Maze.
CONCLUSIONS
Concomitant Cox-Maze in AF patients undergoing MV surgery is associated with better mid-term freedom from AF when compared to PVI with comparable mid-term survival. Large observational studies suggest that there might be a mid-term survival benefit among patients after concomitant Cox-Maze. Further large RCTs with longer standardized follow-up are required to clarify the benefits of concomitant Cox-Maze in AF patients during MV surgery.

OBJECTIVES
This study systematically reviewed the prevalence of pulmonary vein (PV) reconnection in subjects with and without AF recurrence and assessed the relationship between PV reconnection and freedom from atrial fibrillation (AF).
BACKGROUND
Pulmonary vein reconnection is frequently observed in patients experiencing recurrent AF post catheter ablation. However, its prevalence in AF-free patients has not been well studied.
METHODS
An electronic search was performed for studies describing PV electrical conduction in subjects with and without AF recurrence post PV isolation (PVI).
RESULTS
Eleven of 5,665 articles met selection criteria. A total of 683 subjects were included in the meta-analysis; 379 had AF recurrence, and 304 were AF-free. Among patients with AF recurrence, 324 of 379 patients (85.5%) had at least 1 pulmonary vein reconnected. Among AF-free patients, 178 of 304 patients (58.6%) had at least 1 PV electrically reconnected, and 126 of 304 (41.4%) had durable PVI. The relative risk (RR) of recurrent AF was significantly lower with durable PVI than with PV reconnection (RR: 0.57; 95% confidence interval [CI]: 0.37 to 0.86; p = 0.008). Analysis of 7 studies including exclusively paroxysmal AF patients (n = 470) showed RR of 0.69 (95% CI: 0.45 to 1.05; p = 0.09).
CONCLUSIONS
This meta-analysis shows that durable PVI is associated with a lower risk of AF recurrence after catheter ablation. However, the association was modest, and PV electrical reconnection is common, affecting 58% of AF-free patients. Analysis of studies that included exclusively patients with paroxysmal AF showed a weaker relationship. Additional research is warranted to better understand the mechanism(s) of benefit of catheter ablation for AF and investigate whether PVI should be the primary goal.

Review
OBJECTIVES
We performed a systematic review to assess the benefits or risks of physical activity in patients with an acute or previous DVT of the leg.
DATA SOURCES
PubMed, EMBASE and Science Citation Index were searched without language restrictions up to July 2007. Bibliographies of retrieved articles and personal files were also searched.
REVIEW METHODS
Randomized trials and prospective cohort studies that included patients with acute or previous DVT, described an exercise intervention or exercise exposure, and described any related clinical outcome were selected. Data were independently extracted by 2 investigators.
RESULTS
Seven randomized trials and two prospective observational studies were included. Early exercise, compared with bed rest, was associated with a similar short-term risk of pulmonary embolism in patients with acute DVT and led to more rapid resolution of limb pain. In patients with acute DVT, a 6 month daily walking program led to similar degrees of vein recanalization and improvement in quality of life as controls. In patients with previous DVT, 30 min of vigorous treadmill exercise did not worsen venous symptoms and improved calf muscle flexibility; a 6 month exercise training program improved calf muscle strength and pump function; and high levels of physical activity at one month tended to be associated with reduced severity of postthrombotic symptoms during the subsequent 3 months.
CONCLUSIONS
Early walking exercise is safe in patients with acute DVT and may help to reduce acute symptoms. Exercise training does not increase leg symptoms acutely in patients with a previous DVT and may help to prevent or improve the postthrombotic syndrome.

BACKGROUND
Pulmonary vein stenosis (PVS) is an uncommon but known cause of morbidity and mortality in adults and children and can be managed with percutaneous re-vascularization strategies of pulmonary vein balloon angioplasty (PBA) or pulmonary vein stent implantation (PSI).
AIM
To study the safety and efficacy outcomes of PBA PSI in all patient categories with PVS.
METHODS
We performed a literature search of all studies comparing outcomes of patients evaluated by PBA PSI for PVS. We selected all published studies comparing PBA PSI for PVS with reported outcomes of restenosis and procedure-related complications in all patient categories. In adults, PVS following atrial fibrillation ablation and in children PVS related to congenital etiology or post-procedural PVS following total or partial anomalous pulmonary venous return repair were included. The patient-centered outcomes were risk of restenosis requiring re-intervention and procedural-related complications. The meta-analysis was performed by computing odds ratios (ORs) using the random effects model based on underlying statistical heterogeneity.
RESULTS
Eight observational studies treating 768 severe PVS in 487 patients met our inclusion criteria. The age range of patients was 6 months to 70 years and 67% were males. The primary outcome of the re-stenosis requiring re-intervention occurred in 196 of 325 veins in the PBA group and 111 of 443 veins in the PSI group. Compared to PSI, PBA was associated with a significantly increased risk of re-stenosis (OR 2.91, 95%CI: 1.15-7.37, = 0.025, = 79.2%). Secondary outcomes of the procedure-related complications occurred in 7 of 122 patients in the PBA group and 6 of 69 in the PSI group. There were no statistically significant differences in the safety outcomes between the two groups (OR: 0.94, 95%CI: 0.23-3.76, = 0.929), = 0.0%).
CONCLUSION
Across all patient categories with PVS, PSI is associated with reduced risk of re-intervention and is as safe as PBA and should be considered first-line therapy for PVS.

Review
Initial experience suggests that the POLARx cryoballoon system (Boston Scientific) has a similar procedural efficacy and safety as Arctic Front Advance Pro (AFA-Pro, Medtronic). We performed an updated systematic review and meta-analysis comparing POLARx and AFA-Pro. Embase, MEDLINE, Web of Science, Cochrane, and Google Scholar databases were searched until 12/01/2022 for studies comparing POLARx versus AFA-Pro in patients undergoing pulmonary vein (PV) isolation for AF. A total of 8 studies, involving 1146 patients from 11 European centers were included (POLARx n = 317; AFA-Pro n = 819). There were no differences in acute PV isolation, procedure time, fluoroscopy time, ablation time, minimal esophageal temperature, and risk of phrenic nerve palsy or thromboembolic events. Balloon nadir temperatures were lower for POLARx in all PVs. Compared with AFA-Pro, POLARx had a higher rate of first freeze isolation in the left inferior PV (LIPV) (odds ratio [OR]: 2.60; 95 % confidence interval [CI]: 1.06 to 6.43; P = 0.04), higher likelihood of time-to-isolation (TTI) recording in LIPV (OR: 2.91; 95 % CI: 1.54 to 5.49; P = 0.001) and right inferior PV (OR: 3.23; 95 % CI: 1.35 to 7.74; P = 0.008). In contrast, the TTI in LIPV was longer with POLARx in comparison to AFA-Pro (mean difference: 7.61 ; 95 % CI 2.43 to 12.8 ; P = 0.004). In conclusion, POLARx and AFA-Pro have a similar acute outcome. Interestingly, there was a higher rate of TTI recording in the inferior PVs with POLARx. This updated -analysis provides new safety data on esophageal temperature and thromboembolic events.

Meta-Analysis Review
UNLABELLED
Essentials The association of superficial vein thrombosis (SVT) with venous thromboembolism (VTE) is variable. We performed a meta-analysis to assess the prevalence of concomitant VTE in patients with SVT. Deep vein thrombosis was found in 18.1%, and pulmonary embolism in 6.9%, of SVT patients. Screening for VTE may be worthy in some SVT patients to plan adequate anticoagulant treatment.
SUMMARY
Background Some studies have suggested that patients with superficial vein thrombosis (SVT) have a non-negligible risk of concomitant deep vein thrombosis (DVT) or pulmonary embolism (PE) at the time of SVT diagnosis. Unfortunately, the available data on this association are widely variable. Objectives To perform a systematic review and meta-analysis of the literature in order to evaluate the prevalence of concomitant DVT/PE in patients with SVT of the lower limbs. Methods Studies reporting on the presence of DVT/PE in SVT patients were systematically searched for in the PubMed, Web of Science, Scopus and EMBASE databases. The weighted mean prevalence (WMP) of DVT and PE was calculated by use of the random effect model. Results Twenty-one studies (4358 patients) evaluated the prevalence of DVT and 11 studies (2484 patients) evaluated the prevalence of PE in patients with SVT. The WMP of DVT at SVT diagnosis was 18.1% (95%CI: 13.9%, 23.3%) and the WMP of PE was 6.9% (95%CI: 3.9%, 11.8%). Heterogeneity among the studies was substantial. Selection of studies including outpatients only gave similar results (WMP of DVT, 18.2%, 95% CI 12.2-26.3%; and WMP of PE, 8.2%, 95% CI 3.3-18.9%). Younger age, female gender, recent trauma and pregnancy were inversely associated with the presence of DVT/PE in SVT patients. Conclusions The results of our large meta-analysis suggest that the prevalence of DVT and PE in patients presenting with SVT is not negligible. Screening for a major thromboembolic event may be worthwhile in some SVT patients, in order to allow adequate anticoagulant treatment to be planned. Other high-quality studies are warranted to confirm our findings.
