Background
The Tama-REgistry of Acute endovascular Thrombectomy (TREAT) is a multicenter registry of endovascular thrombectomy in the Tama area of Tokyo. The objective of this study was to confirm the real-world status of 2 paradigms of transportation.Methods
This was a retrospective analysis of data from TREAT. Patients were divided into 2 groups and 2 periods: directly admitted to an endovascular thrombectomy-capable center (ECC; group D)/secondary transfer from a non-ECC (group S), and the first period/the second period. Transfer distance, workflow metrics, and clinical outcomes were analyzed.Results
A total of 326 patients, including 264 in group D and 62 in group S, were analyzed. The median distance from the onset-to-ECC was 3.62km for group D and 7.87km for group S (P < .001). The median onset-to-needle (OTN) time was longer for group S (168 minutes) than group D (138 minutes; P?=?.006). The median onset-to-reperfusion (OTR) time was significantly shorter for group D (247 minutes) than for group S (304 minutes; P?=?.029). With respect to the 2 periods, there was no significant difference in onset-to-puncture time between the 2 groups in the first period (207 minutes versus 243.5 minutes, respectively, P?=?.50), while there was one in the second period (164 minutes versus 246.5 minutes, respectively, P?=?.02).Conclusions
This region-wide registry study showed longer OTN and OTR times, with no improvement of the time course over time in patients transported via non-ECCs. These results should be used to create a regional medical policy for the management of acute ischemic stroke. 相似文献2.

While the incidence of oropharyngeal squamous cell carcinoma (OPSCC) has been increasing in these two decades, primarily due to human papillomavirus (HPV), stratification of OPSCC into molecular subgroups showing different clinicopathological features has not been fully investigated. We performed DNA methylome analysis using Infinium 450k for 170 OPSCC cases, including 89 cases in our cohort and 81 cases reported by The Cancer Genome Atlas, together with targeted exon sequencing analysis. We stratified OPSCC by hierarchical clustering analysis using methylome data. Methylation levels of classifier markers were validated quantitatively using pyrosequencing, and area under the curve (AUC) values of receiver operating characteristics (ROC) curves were calculated. OPSCC was stratified into four epigenotypes: HPV(+) high-methylation (OP1), HPV(+) intermediate-methylation (OP2), HPV(−) intermediate-methylation (OP3) and HPV(−) low-methylation (OP4). Ten methylation marker genes were generated: five to classify HPV(+) cases into OP1 and OP2, and five to classify HPV(−) cases into OP3 and OP4. AUC values of ROC curves were 0.969 and 0.952 for the two marker panels, respectively. While significantly higher TP53 mutation and CCND1 copy number gains were observed in HPV(−) than in HPV(+) groups (p < 0.01), no significant difference of genomic aberrations was observed between OP1 and OP2, or OP3 and OP4. The four epigenotypes showed significantly different prognosis (p = 0.0006), distinguishing the most favorable OPSCC subgroup (OP1) among generally favorable HPV(+) cases, and the most unfavorable OPSCC subgroup (OP3) among generally unfavorable HPV(−) cases. HPV(+) and HPV(−) OPSCC are further divided into distinct DNA methylation epigenotypes, showing significantly different prognosis. 相似文献

BackgroundPathogenic mitochondrial (mt)DNA mutations, which often cause life‐threatening disorders, are maternally inherited via the cytoplasm of oocytes. Mitochondrial replacement therapy (MRT) is expected to prevent second‐generation transmission of mtDNA mutations. However, MRT may affect the function of respiratory chain complexes comprised of both nuclear and mitochondrial proteins.MethodsBased on the literature and current regulatory guidelines (especially in Japan), we analyzed and reviewed the recent developments in human models of MRT.Main findingsMRT does not compromise pre‐implantation development or stem cell isolation. Mitochondrial function in stem cells after MRT is also normal. Although mtDNA carryover is usually less than 0.5%, even low levels of heteroplasmy can affect the stability of the mtDNA genotype, and directional or stochastic mtDNA drift occurs in a subset of stem cell lines (mtDNA genetic drift). MRT could prevent serious genetic disorders from being passed on to the offspring. However, it should be noted that this technique currently poses significant risks for use in embryos designed for implantation.ConclusionThe maternal genome is fundamentally compatible with different mitochondrial genotypes, and vertical inheritance is not required for normal mitochondrial function. Unresolved questions regarding mtDNA genetic drift can be addressed by basic research using MRT. 相似文献
