Background and Aims: With rapid changes in the management landscape of chronic hepatitis B (CHB), this technical systematic review addresses 4 critical Population, Intervention, Comparator, Outcome (PICO) questions to provide guidance to the formulation of recommendations to the 2025 AASLD practice guideline for management of CHB. Approach: The review was reported in accordance with PRISMA guidelines. Outcomes were evaluated across 4 key PICOs: (1) antiviral therapy for prevention of horizontal HBV transmission in high-risk groups, (2) antiviral therapy versus observation for persons in the immune-tolerant phase, (3) discontinuation versus continuation of nucleos(t)ide analogue therapy in HBeAg-negative individuals with undetectable HBV DNA, and (4) hepatocellular carcinoma (HCC) surveillance in non-cirrhotic individuals with HBsAg clearance or co-infections with HCV, HDV, or HIV. Results: For PICO 1, limited evidence suggests antiviral therapy may reduce horizontal transmission risk, though with low certainty. PICO 2 analyses reveal uncertain benefits of treating persons in the immune-tolerant phase, with very low certainty due to heterogeneity and bias. PICO 3 analyses demonstrate that discontinuing antiviral therapy in persons who are HBeAg negative with undetectable HBV DNA increases HBsAg loss rates (OR: 12.65, 95% CI: 1.58–101.51) but carries moderate risks of virologic relapse (OR: 47.17, 95% CI: 2.79–797.35) and clinical flares. PICO 4 analyses on several cohort studies showed that in patients co-infected with HCV, HBV, or HIV, the annual incidence of HCC was higher than the level where screening becomes cost-effective, suggesting that regular liver cancer screening could be beneficial for these patients. Conclusions: Despite low certainty, the findings support shared decision-making in high-risk horizontal transmission scenarios or in treating individuals in the immune tolerance phase, caution in discontinuing antiviral therapy in virologically suppressed individuals without HBsAg loss, and tailored HCC surveillance for those with co-infection or cirrhosis.
The Methodological Quality of Case Series Published Early vs. Late in the Course of a Pandemic: A Meta-Epidemiologic Study
Abstract Introduction Case reports and series are critical to guide initial decision-making in a pandemic, but may have lower rigor because of the need to publish them quickly. This meta-epidemiologic study compares the methodological quality of case series that described the acute coronavirus disease 2019 (COVID-19) pandemic in 2020 versus those that described long-haul cases. Methods We conducted a systematic review in multiple databases for long-haul case series and reports. We identified early cases of acute COVID-19 synthesized in published systematic reviews. We evaluated the methodological quality by pairs of independent reviewers using a tool dedicated for appraising case series. Results We included 239 original case series (81 published in the first year of the pandemic and 158 published later describing long-haul COVID). The methodological quality of both groups of case series was very good (80–100% of series satisfying quality items) except for two items, the selection approach of cases included in the series and ruling out other causes that can explain the main finding described in the series. The appraisal tool demonstrated high agreement and reliability between reviewers. Conclusion The methodological quality of modern case series is high, except for two quality items that represent an area for potential for improvement for authors of case series describing future pandemics.
Endovascular thrombectomy for severe cerebral venous thrombosis: A comprehensive meta-analysis assessing safety and efficacy
Background Cerebral sinus venous thrombosis (CSVT) has traditionally been treated medically with systemic anticoagulation. Recent advances in endovascular therapy (EVT) may represent an alternative treatment to medical therapy for CSVT. We conducted a systematic review and meta-analysis to evaluate the use of EVT for CSVT. Methods We conducted a systematic literature review using PubMed, Embase, Scopus, and Web of Science. We included studies that reported outcomes following EVT for CSVT. The primary outcome of interest was rate of modified Rankin Scale (mRS) 0–2. Secondary outcomes of interest were rates of complete, partial, and failed recanalization, mortality, and new or expansion of hematoma. We calculated pooled rates (%) and their corresponding 95% confidence intervals (CIs). Results Thirty-eight studies with 682 patients were included. Rate of mRS 0–2 was 82.6% (95% CI, 75.3%–88.0%). Rate of complete recanalization was 60.9% (95% CI, 49.1%–71.5%), rate of partial recanalization was 34.2% (95% CI, 24.1%–45.9%), and rate of failed recanalization was 5.4% (95% CI, 3.1%–9.2%). Rate of mortality was 6.7% (95% CI, 4.1%–10.8%), and rate of new hematoma or expansion of hematoma was 5.1% (2.9%–8.8%). Conclusions In this systematic review and meta-analysis, EVT for CSVT was associated with favorable rates of mRS 0–2 and recanalization. Furthermore, EVT was associated with a promising safety profile. Future prospective, comparative studies are warranted to assess EVT for CSVT.
Cardiac CT vs Echocardiography for Intracardiac Thrombus Detection in Ischemic Stroke
ImportanceEndovascular thrombectomy (EVT) is standard treatment for acute ischemic stroke (AIS) due to large-vessel occlusion (LVO), but optimal post-EVT blood pressure (BP) control remains debated.ObjectiveTo assess the association of different systolic BP targets following EVT with functional outcomes, mortality, and complications in patients with AIS due to LVO.Data SourcesSystematic review and meta-analysis of databases (PubMed, Embase, Web of Science, Scopus, and Cochrane Library) to September 8, 2023.Study SelectionInclusion criteria consisted of randomized clinical trials examining post-EVT management of systolic BP in patients with AIS and LVO comparing intensive vs conventional targets. Nonrandomized studies, observational studies, noninterventional trials, meeting abstracts, duplicate studies, studies with overlapping data, and non–English language studies were excluded. Two authors independently applied these criteria through a blinded review, with discrepancies resolved through consensus. The risk of bias in the included studies was assessed using the revised tool for assessing risk of bias in randomized trials.Data Extraction and SynthesisThis study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline. Three authors extracted data regarding study characteristics, baseline patient data, and outcomes of interest. The pooled data were analyzed using a random-effects meta-analysis.Main Outcomes and MeasuresRates of functional independence, 90-day mortality, symptomatic intracranial hemorrhage, and hypotensive events.ResultsA total of 4 randomized clinical trials with 1571 initially enrolled patients were included in the analysis. Lower functional independence rates were observed in the intensive control group (relative risk [RR], 0.81 [95% CI, 0.67-0.98]). No significant differences were found in 90-day mortality (RR, 1.18 [95% CI, 0.92-1.52]), symptomatic intracranial hemorrhage (RR, 1.12 [95% CI, 0.75-1.67]), or hypotensive events (RR, 1.80 [95% CI, 0.37-8.76]). There was minimal heterogeneity among the studies included in the functional independence outcome (I2 = 13% and τ2 = 0.003), which was absent among other outcomes (I2 = 0 and τ2 = 0).Conclusions and RelevanceThese findings suggest that intensive post-EVT BP reduction does not yield benefits and may carry risks. While awaiting the results of additional ongoing trials, a conservative BP management strategy after endovascular recanalization is favored in daily practice.
Safety and efficacy of the Woven Endo-Bridge-17 device for intracranial aneurysm treatment: A systematic review and meta-analysis
Background The Woven Endo-Bridge (WEB) device revolutionized the treatment of wide-necked bifurcation aneurysms by intrasaccular flow diversion. The latest advancement is the WEB-17 system, offering greater flexibility with fewer wires, enabling treatment of smaller distal aneurysms using smaller microcatheters than the WEB-21 system. Methods We conducted a systematic review following preferred reporting items for systematic reviews and meta-analyses guidelines, analyzing data from seven retrospective cohort studies involving 483 aneurysms treated with the WEB-17 device. Statistical analysis computed pooled prevalence rates and 95% confidence intervals using appropriate models for each outcome and R software version 4.3.1 (R Foundation for Statistical Computing, Vienna, Austria). Results Technical success was achieved in 475 out of 483 aneurysms treated with the WEB-17 device, with a success rate of 98.34% (95% confidence interval (CI) = 96.72–99.17). Among the successful cases, 4.97% (95% CI = 1.60–14.39) required adjunctive devices. Adequate occlusion, defined as complete occlusion or neck remnants, was observed in 94.41% (95% CI = 88.17–97.46) of cases. Periprocedural complications were infrequent, with thromboembolic complications occurring in 4.93% (95% CI = 3.29–7.30) of cases, hemorrhagic complications in 1.28% (95% CI = 0.58–2.83), and postprocedural neurologic complications in 0.99% (95% CI = 0.31–3.14). Procedure-related morbidity was observed in 1.71% (95% CI = 0.86–3.39) of cases, and there was one procedure-related mortality reported at 0.21% (95% CI = .03–1.50). Mortality unrelated to the procedure occurred in 1% (95% CI = 0.23–4.15). Conclusion Our findings suggest that the WEB-17 device is associated with a high rate of technical success, favorable angiographic outcomes, and a low rate of periprocedural complications. Further research, including prospective trials, is needed to confirm these findings and establish its safety and efficacy definitively.
