    • Declines in stroke admission, IV thrombolysis (IVT), and mechanical thrombectomy volumes were reported during the first wave of the COVID-19 pandemic. There is a paucity of data on the longer-term effect of the pandemic on stroke volumes over the course of a year and through the second wave of the pandemic. We sought to measure the effect of the COVID-19 pandemic on the volumes of stroke admissions, intracranial hemorrhage (ICH), IVT, and mechanical thrombectomy over a 1-year period at the onset of the pandemic (March 1, 2020, to February 28, 2021) compared with the immediately preceding year (March 1, 2019, to February 29, 2020).We conducted a longitudinal retrospective study across 6 continents, 56 countries, and 275 stroke centers. We collected volume data for COVID-19 admissions and 4 stroke metrics: ischemic stroke admissions, ICH admissions, IVT treatments, and mechanical thrombectomy procedures. Diagnoses were identified by their ICD-10 codes or classifications in stroke databases.There were 148,895 stroke admissions in the 1 year immediately before compared with 138,453 admissions during the 1-year pandemic, representing a 7% decline (95% CI [95% CI 7.1-6.9]; p < 0.0001). ICH volumes declined from 29,585 to 28,156 (4.8% [5.1-4.6]; p < 0.0001) and IVT volume from 24,584 to 23,077 (6.1% [6.4-5.8]; p < 0.0001). Larger declines were observed at high-volume compared with low-volume centers (all p < 0.0001). There was no significant change in mechanical thrombectomy volumes (0.7% [0.6-0.9]; p = 0.49). Stroke was diagnosed in 1.3% [1.31-1.38] of 406,792 COVID-19 hospitalizations. SARS-CoV-2 infection was present in 2.9% ([2.82-2.97], 5,656/195,539) of all stroke hospitalizations.There was a global decline and shift to lower-volume centers of stroke admission volumes, ICH volumes, and IVT volumes during the 1st year of the COVID-19 pandemic compared with the prior year. Mechanical thrombectomy volumes were preserved. These results suggest preservation in the stroke care of higher severity of disease through the first pandemic year.This study is registered under NCT04934020.

  • Molecular characterization of exosomes and their microRNA cargo in human follicular fluid: bioinformatic analysis reveals that exosomal microRNAs control pathways involved in follicular maturation
  • 2014
  • Ingår i: Fertility and Sterility. - : Elsevier BV. - 0015-0282. ; 102:6
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To characterize well-represented microRNAs in human follicular fluid (FF) and to ascertain whether they are cargo of FF exosomes and whether they are involved in the regulation of follicle maturation. Design: FF exosomes were characterized by nanosight, flow cytometry, and exosome-specific surface markers. Expression microRNA profiles from total and exosomal FF were compared with those from plasma of the same women. Patient(s): Fifteen healthy women who had undergone intracytoplasmic sperm injection. Main Outcome Measure(s): TaqMan low-density array to investigate the expression profile of 384 microRNAs; DataAssist and geNorm for endogenous control identification; significance analysis of microarrays to identify differentially expressed microRNAs; nanosight, flow-cytometry, and bioanalyzer for exosome characterization; bioinformatic tools for microRNAs target prediction, gene ontology, and pathway analysis. Result(s): We identified 37 microRNAs upregulated in FF as compared with plasma from the same women. Thirty-two were carried by microvesicles that showed the well-characterized exosomal markers CD63 and CD81. These FF microRNAs are involved in critically important pathways for follicle growth and oocyte maturation. Specifically, nine of them target and negatively regulate mRNAs expressed in the follicular microenvironment encoding inhibitors of follicle maturation and meiosis resumption. Conclusion(s): This study identified a series of exosomal microRNAs that are highly represented in human FF and are involved in follicular maturation. They could represent noninvasive biomarkers of oocyte quality in assisted reproductive technology. (C) 2014 by American Society for Reproductive Medicine.

  • Registry of the International Society of Uterus Transplantation: First Report
  • 2023
  • Ingår i: Transplantation. - : Ovid Technologies (Wolters Kluwer Health). - 0041-1337. ; 107:1, s. 10-17
  • Tidskriftsartikel (refereegranskat)abstract
    • Background.Uterus transplantation (UTx) is a novel type of transplantation to treat infertility in women with an absent or nonfunctioning uterus. The International Society of Uterus Transplantation (ISUTx) has developed a registry to monitor worldwide UTx activities while serving as a repository for specific research questions. Methods.The web-based registry has separate data fields for donor, recipient, surgeries, immunosuppression, rejections, pregnancies with live birth(s), and transplant hysterectomies. Data are prospectively registered. Results.A total of 45 UTx procedures have been registered; the majority (78%) of those procedures were live donor (LD) transplants. Median age of the LDs, deceased donors, and recipients were 50 y (range 32-62), 38.5 y (19-57), and 29 y (22-38), respectively. The duration of LD surgery was approximately twice as long as the recipient surgery. Postoperative complications of any Clavien-Dindo grade were registered in 20% of LDs and 24% of recipients. Rejection episodes were more frequent (33%) early after transplantation (months 1-5) compared with later time points (months 6-10; 21%). Healthy neonates were delivered by 16 recipients, with 3 women giving birth twice. The total live birth rate per embryo transfer was 35.8%. Median length of pregnancy was 35 gestational weeks. Twelve uteri were removed without childbirth, with 9 transplant hysterectomies occurring during the initial 7 mo post-UTx. Conclusions.A mandatory registry is critical to determine quality and process improvement for any novel transplantation. This registry provides a detailed analysis of 45 UTx procedures performed worldwide with a thorough analysis of outcomes and complications.

  • Safety and Outcome of Revascularization Treatment in Patients With Acute Ischemic Stroke and COVID-19: The Global COVID-19 Stroke Registry.
  • 2023

    • COVID-19-related inflammation, endothelial dysfunction, and coagulopathy may increase the bleeding risk and lower the efficacy of revascularization treatments in patients with acute ischemic stroke (AIS). We aimed to evaluate the safety and outcomes of revascularization treatments in patients with AIS and COVID-19.This was a retrospective multicenter cohort study of consecutive patients with AIS receiving intravenous thrombolysis (IVT) and/or endovascular treatment (EVT) between March 2020 and June 2021 tested for severe acute respiratory syndrome coronavirus 2 infection. With a doubly robust model combining propensity score weighting and multivariate regression, we studied the association of COVID-19 with intracranial bleeding complications and clinical outcomes. Subgroup analyses were performed according to treatment groups (IVT-only and EVT).Of a total of 15,128 included patients from 105 centers, 853 (5.6%) were diagnosed with COVID-19; of those, 5,848 (38.7%) patients received IVT-only and 9,280 (61.3%) EVT (with or without IVT). Patients with COVID-19 had a higher rate of symptomatic intracerebral hemorrhage (SICH) (adjusted OR 1.53; 95% CI 1.16-2.01), symptomatic subarachnoid hemorrhage (SSAH) (OR 1.80; 95% CI 1.20-2.69), SICH and/or SSAH combined (OR 1.56; 95% CI 1.23-1.99), 24-hour mortality (OR 2.47; 95% CI 1.58-3.86), and 3-month mortality (OR 1.88; 95% CI 1.52-2.33). Patients with COVID-19 also had an unfavorable shift in the distribution of the modified Rankin score at 3 months (OR 1.42; 95% CI 1.26-1.60).Patients with AIS and COVID-19 showed higher rates of intracranial bleeding complications and worse clinical outcomes after revascularization treatments than contemporaneous non-COVID-19 patients receiving treatment. Current available data do not allow direct conclusions to be drawn on the effectiveness of revascularization treatments in patients with COVID-19 or to establish different treatment recommendations in this subgroup of patients with ischemic stroke. Our findings can be taken into consideration for treatment decisions, patient monitoring, and establishing prognosis.The study was registered under ClinicalTrials.gov identifier NCT04895462.
