BackgroundFew clinical studies perform detailed analyses of subtypes of intracranial hemorrhage (ICH) after mechanical thrombectomy (MT) used to treat acute ischemic stroke. Symptomatic intracranial hemorrhage (sICH) is a formidable complication of MT and is widely used in clinical trials as a safety outcome. However, variable definitions of sICH are used across clinical studies.ObjectiveTo radiographically subcategorize post-MT ICH development within this large cohort and examine overlap with sICH. Second, to examine the agreement of this definition of sICH with local site-reported occurrences of sICH to see how sICH rates change with modifications of the definitions used.MethodsA large cohort of patients treated with MT for acute ischemic stroke (n=1395) was analyzed to (1) radiographically characterize hemorrhagic subtypes of intracranial hemorrhage (ICH) occurring after MT; (2) examine associations of hemorrhagic subtypes with sICH; and (3) compare core laboratory-adjudicated occurrences of sICH with site-reported sICH.ResultsThe overall rate of ICH was 552/1395 patients (39.6%), and the overall rate of sICH was 47/1395 (3.4%). The most common type of ICH was hemorrhagic infarction type 1 (HI1), which represented 45.3% of all ICH cases– followed by HI2 (31.5%) and subarachnoid hemorrhage (SAH, 29.2%). Parenchymal hematoma 2 (PH2) represented only 3.3% of all ICH cases. Of the PH2 hemorrhages, only 33.3% were determined to be symptomatic. Of sICH cases, the most common ICH subtypes were HI2 (48.9%) and SAH (38.3%). Comparison of sICH rates as determined by core laboratory adjudication versus local site-reported results showed that only 14 patients were identified as having sICH with both definitions, with 47 patients total with sICH according to one definition, but not the other.ConclusionsResults of this analysis demonstrate the radiographic subtypes of ICH and also highlight the limitations of variable criteria used to define sICH, suggesting that it might be appropriate to revisit how sICH is defined post-MT.Trial registration numberClinical trial NCT03845491.

Fibrillary and immunotactoid glomerulonephritis: Distinct entities with different clinical and pathologic features. Controversy surrounds the relatedness of fibrillary glomerulonephritis (FGN) and immunotactoid glomerulonephritis (IT). To better define their clinicopathologic features and outcome, we report the largest single center series of 67 cases biopsied from 1980 to 2001, including 61 FGN and 6 IT. FGN was defined by glomerular immune deposition of Congo red–negative randomly oriented fibrils of < 30 nm (mean, 20.1 ± 0.4 nm). IT was defined by glomerular deposition of hollow, stacked microtubules of ≥ 30 nm (mean, 38.2 ± 5.7 nm). FGN comprised 0.6% of total native kidney biopsies and IT was tenfold more rare (0.06%). Deposits in FGN were immunoglobulin G (IgG) dominant and polyclonal in 96%. IgG subtype analysis in 19 FGN cases showed monotypic deposits in four (two IgG1 and two IgG4) and oligotypic deposits in 15 (all combined IgG1 and IgG4). In IT, deposits were IgG dominant in 83% and monoclonal in 67% (three IgG1κ and one IgG1λ). FGN patients were a mean age of 57 years, 92% were Caucasian, and 39% were male. At biopsy, FGN patients had the following clinical characteristics (mean, range): creatinine 3.1 mg/dL (0.5 to 14), proteinuria 6.5 g/day (0.8 to 25), 60% microhematuria, and 59% hypertension. Histologic patterns of FGN were diverse, including diffuse proliferative glomerulonephritis (DPGN) (nine cases), membranoproliferative glomerulonephritis (MPGN) (27 cases), mesangial proliferative/sclerosing (MES) (13), membranous glomerulonephritis (MGN) (four), and diffuse sclerosing (DS) (eight). The more proliferative (MPGN and DPGN) and sclerosing (DS) forms presented with a higher creatinine and greater proteinuria compared to MES and MGN. Median time to end-stage renal disease (ESRD) was 24.4 months for FGN and mean time to ESRD varied by histologic subtype: DS 7 months, DPGN 20 months, MPGN 44 months, compared to MES 80 months and MGN 87 months. There was no statistically significant effect of immunosuppressive therapy (given to 36% of FGN patients). By Cox regression (hazard ratio, confidence interval, P value), independent predictors of progression to ESRD were creatinine at biopsy [2.05 (1.55 to 2.72) P < 0.001] and severity of interstitial fibrosis [2.01 (1.05 to 3.85) P = 0.034]. Although IT had similar presentation, histologic patterns, and outcome compared to FGN, it had a greater association with monoclonal gammopathy (P = 0.014), underlying lymphoproliferative disease (P = 0.020), and hypocomplementemia (P = 0.032). FGN is an idiopathic condition characterized by polyclonal immune deposits with restricted gamma isotypes. Most patients present with significant renal insufficiency and have a poor outcome despite immunosuppressive therapy, and outcome correlates with histologic subtype. By contrast, IT often contains monoclonal IgG deposits and has a significant association with underlying dysproteinemia and hypocomplementemia. Differentiation of FGN from the much more rare entity IT appears justified on immunopathologic, ultrastructural, and clinical grounds.

ObjectivesTo explore the relationship between final expanded treatment in cerebral infarction (eTICI) score and the presence or absence of distal emboli on final angiography on clinical outcome after endovascular thrombectomy (EVT) for acute ischaemic stroke (AIS). Persistent distal emboli on angiography are commonly noted, yet not all patients with intermediate eTICI scores demonstrate clear angiographic emboli, raising the possibility that these angiographic differences may correlate with distinct mechanisms of ‘no-reflow’. Therefore, we sought to better understand the potential clinical impact of such angiographic markers in cases of incomplete reperfusion.DesignWe performed an exploratory retrospective analysis of a prospectively collected group of AIS patients who underwent EVT for M1 occlusions using the ASSIST Registry.Setting71 sites in 11 countries participated in the registry.ParticipantsA total of 650 patients with M1 occlusions were included.Main outcome measuresWe compared 90-day modified Rankin scale (mRS) scores based on eTICI score as well as the presence or absence of distal emboli on final angiography.ResultsClinical outcome based only on eTICI score revealed a shift in 90-day mRS, with a significant difference across eTICI scores in predicting 90-day mRS 0–2. In the intermediate eTICI grades 2b67 and 2c, there was a trend towards better 90-day mRS when emboli were present on final angiography than when emboli were absent. However, pairwise comparisons between these levels were non-significant.ConclusionIn patients with final eTICI 2b67 or 2c, those with persistent emboli trended towards better clinical outcomes. With intermediate eTICI reperfusion, identifying the presence or absence of distal emboli on final angiography may be useful in distinguishing patterns of incomplete reperfusion. These findings should be followed by investigations on correlation between angiography and other markers of microcirculatory ‘no-reflow’.Trial registration numberNCT03845491.

The phylum Cnidaria is the outgroup of Bilateria and includes sea anemones, corals, hydroids, and jellyfish. Cnidarians play crucial ecological roles in marine ecosystems, including the formation of highly diverse and productive coral reefs, and acting as important predator and prey species. Cnidarians are also well known for their remarkable regeneration capacities. Here, we report single-cell RNA sequencing during bell regeneration in two species of scyphozoans or true jellyfish, Aurelia coerulea and Rhopilema esculentum. We delineated 12 cell populations in Aurelia and Rhopilema, and revealed their respective marker genes and enriched gene pathways. Conserved transcription factor Otx and Wnt/β-catenin signalling pathway genes were identified during regeneration processes. Additionally, we discovered two conserved, sequentially activated modules during regeneration, with stem cells, gastrodermal cells, neural cells, and secretory gland cells modulated in the first phase, followed by cnidocytes in the second phase. Further comparison among cnidarian genomes identified a suite of scyphozoan lineage-specific genes, a subset of which were frequently significantly expressed in cnidocytes in both jellyfish species during the first phase of regeneration. This study reveals key insights into the evolution and contribution of conserved and novel genes to the formation of lineage-specific genetic networks and biological processes.
