Comparision of Mechanical Thrombectomy With Contact Aspiration or Stent Retriever in Patients With Large-vessel Occlusion in Acute Ischemic Stroke.

OBJECTIVES: Whether the direct aspiration approach of thrombectomy for recanalization in patients with acute ischemic stroke has a similar efficacy and safety compared to the stent-retriever still remains uncertain. METHODS: A retrospective data analysis was performed to identify patients with large cerebral artery acute ischemic stroke treated with endovascular thrombectomy. The study was conducted between January 2018 and December 2019 in a single stroke center. RESULTS: Twenty patients met inclusion criteria for this study with a mean age 66.64 ±â€Š17.92 years' old. The symptom occurred on the left side were in 13, and the right side in 7. The location of occlusion was 8 in M1 of the middle cerebral artery of M2, and 6 in internal carotid artery. Nine patients were randomized to first-line treatment with contact aspiration and eleven to first-line treatment with a stent retriever. The mean time from admission time to groin puncture was 55.51 ±â€Š31.03 minutes. The average time from groin puncture to maximal revascularizion after mechanical thrombectomy was 50.9 ±â€Š22.5 minutes in contact aspiration group, but this time was 71.37 ±â€Š25.45 minutes in the group of stent retriever. The overall successful revascularization rate (TICI 2b-3) was 88.9% in contact aspiration (TICI2a = 1, TICI 2b = 4 patients, TICI 3 = 4 patients), and 90.1% in stent retriever (TICI2a = 1, TICI 2b = 6 patients, TICI 3 = 4 patients). DISCUSSION: First-line thrombectomy with contact aspiration did not result in a higher successful revascularization rate at the end of the procedure but had a short time from groin puncture to maximal revascularizion.

Maternal periconceptional folate status and infant atopic dermatitis: A prospective cohort study.

BACKGROUND: Maternal folate status is linked with the risk of allergic disorders including atopic dermatitis (AD) in children, but findings remain inconclusive. We aim to assess the relationship between maternal folate status in early gestation and early-onset infant AD, based on a prospective mother-child cohort study. METHODS: Pregnant women were recruited at 12-14 weeks of gestation. Red blood cell folate (RBC folate) and serum folate concentrations were examined at enrollment. Periconceptional folic acid supplementation was investigated through a self-administered questionnaire. The primary outcome was AD incidence before 6 months of age, diagnosed according to Williams' criteria. Multivariate logistic regression was used to evaluate associations of maternal folate status with infant AD by adjusting parental and child covariates. RESULTS: In total, 107 (23.4%) of 458 infants developed AD before 6 months, with more male infants affected (P = .002). Higher maternal RBC folate levels (per 100 ng/mL) were associated with an increased risk of AD (adjusted odds ratio [aOR] 1.16, 95% confidence interval [CI] 1.04-1.31). An RBC folate level ≥620 ng/mL was associated with increased infant AD by 91% (aOR 1.91, 95% CI 1.09-3.36). However, associations were not observed for maternal serum folate at early gestation or periconceptional folic acid supplement intakes. CONCLUSIONS: We provide the first evidence that higher maternal RBC folate concentrations during early gestation are associated with increased early-onset infant AD. Our findings support the importance of maintaining appropriate folate levels during the periconceptional period to reduce the risk of AD in infants.
