BackgroundThe crucial role of thrombectomy in the management of emergent large vessel occlusive stroke is not disputed but there is a technical failure rate in a significant minority of patients whose outcomes are often poor. Our objective was to perform a systematic review and meta-analysis to assess the safety and efficacy of permanent self-expandable stent deployment as a bailout procedure in cases of failed anterior circulation thrombectomy.MethodsTwo independent reviewers searched the Pubmed (Medline) database for studies reporting outcomes following failed endovascular thrombectomy with subsequent rescue therapy employing self-expandable stents.ResultsEight studies (one prospective, seven retrospective) originating from Europe, Asia, and America comprising 160 patients met the inclusion criteria. Estimated baseline National Institutes of Health Stroke Scale score was 17.1 (95% CI 15.7 to 18.4). Following failed thrombetcomy and stent deployment, the rate of favorable outcome (modified Rankin Scale score 0–2) was 43% (95% CI 34% to 53%). Pooled mortality was 21% (95% CI 13% to 33%). Successful recanalization (Thrombolysis in Cerebral Infarction (TICI) 2b–3 or Thrombolysis in Myocardial Infarction (TIMI) 2–3) was 71% (95% CI 63% to 77%). Symptomatic intracerebral hemorrhage was seen in 12% (95% CI 7% to 18%). The Solitaire stent (Medtronic) was the most commonly deployed stent following failed thrombectomy attempts (66%; 95% CI 31% to 89%). Pre- or post-stent angioplasty was performed in 39%of patients (95% CI 29% to 48%). Glycoprotein IIb/IIIa inhibitors were used in 89% (95% CI 71% to 97%). 95% of patients received postprocedural antiplatelet therapy.ConclusionA rescue stent procedure seems reasonable as a last resort following failed thrombectomy but currently the level of evidence is limited. Prospective registries may aid in guiding future recommendations.

Abstract Background Differentiated thyroid carcinoma (DTC) has an excellent prognosis and the role of high-sensitive thyroglobulin measured during levothyroxine (ON-T4 hs-Tg) testing to discriminate patients with structural from not-evidence of disease (SED and NED, respectively) has been investigated. We conducted a systematic review and meta-analysis evaluating the performance of ON-T4 hs-Tg in two clinical scenarios considering its negative predictive value (NPV) as primary outcome: (1) diagnostic performance of Tg when undetectable value and NED status are simultaneously demonstrated; (2) prognostic performance of undetectable Tg in predicting NED in the subsequent follow-up. Methods This systematic review and meta-analysis were registered on PROSPERO (CRD42019125092). PubMed, Scopus, CENTRAL and Web of Science were searched until February 12, 2019. Original articles reporting data on SED/NED in patients with detectable/undetectable ON-T4 hs-Tg were selected. Summary operating points were estimated using a random-effects model. Results Out of 1413 retrieved papers, 10 studies evaluating 1796 patients were included. Participants were outpatients diagnosed with DTC, treated with near-total (NTx) or total thyroidectomy (TTx) with or without radioactive iodine (RAI). The NPV of ON-T4 hs-Tg for diagnostic and prognostic performance was 99.4% (95% CI 98.9–99.9; I2 = 13%) and 99.4% (95% CI 98.8–100; I2 = 0%), respectively. Conclusions Our findings show that ON-T4 hs-Tg is an excellent diagnostic tool and prognostic factor to rule-out SED. A high level of evidence is provided to decrease the intensity and frequency of follow-up in those DTC patients having undetectable high-sensitive Tg.

ObjectiveTo evaluate the safety and efficacy of intra-arterial thrombolysis (IAT) as an adjunct to endovascular thrombectomy (EVT) in ischemic stroke, we performed a systematic review and meta-analysis of the literature.MethodsSearches were performed using Medline, Embase, and Cochrane databases for studies that compared EVT to EVT with adjunctive IAT (EVT+IAT). Safety outcomes included symptomatic intracerebral hemorrhage (sICH) and mortality at three months. Efficacy outcomes included successful reperfusion (Thrombolysis in Cerebral Infarction score of 2b to 3), and functional independence, defined as a modified Rankin Scale score of 0 to 2 at three months.ResultsFive studies were identified that compared combined EVT+IAT (IA alteplase or urokinase) to EVT-only, and were included in the random effects meta-analysis. There were 1693 EVT patients, including 269 patients treated with combined EVT+IAT and 1424 patients receiving EVT-only. Pooled analysis did not demonstrate any differences between EVT+IAT and EVT-only in rates of sICH (OR: 0.61, 95% CI: 0.20-1.85; P=0.78), mortality (OR: 0.77, 95% CI: 0.54-1.10; P=0.15), or successful reperfusion (OR: 1.05, 95% CI: 0.52-2.15; P=0.89). There was a higher rate of functional independence in patients treated with EVT+IAT, although this was not statistically significant (OR: 1.34, 95% CI: 1.00-1.80; P=0.053).ConclusionsAdjunctive IAT appears to be safe. In specific situations, neurointerventionists may be justified in administering small doses of intraarterial alteplase or urokinase as rescue therapy during EVT.

This systematic review aimed to find attitudes toward Altruistic and Game-playing love styles across individualistic and collectivistic cultures. Addressing major moderators concerning Altruistic and Game-playing love styles are the secondary objectives of this review. This review included 102 articles comprising samples from 37 countries (N = 41997). The findings of this meta-analysis show that there is a collectivistic and individualistic difference in Game-playing but not in the Altruistic love style. Collectivistic and individualistic cultures, on average, demonstrate the same perception concerning the Altruistic love style, whereas collectivistic culture shows the Game-playing love style more strongly. To explain the role of moderators in key measures, the subgroup analysis and meta-regression show that both Game-playing and Altruistic love styles decline by increasing the length of the relationship. Likewise, having children affects these love styles such that the Altruistic love style is improved, and the Game-playing love style is reduced by the presence of children in families.
