Évolutions de la jurisprudence, de la politique relative au droit du travail et de la protection sociale au Japon

Le législateur est moins actif en matière du droit du travail et du droit de la protection sociale depuis fin 2021. Le gouvernement et les partis politiques au pouvoir n’ont en effet pas voulu aborder des sujets susceptibles de provoquer des débats politiques avant les élections législatives du Shangi-In (à peu près équivalent au Sénat) prévues en septembre 2022. Pourtant, en droit du travail, nous relevons un arrêt important de la Cour Suprême relatif au droit de la négociation collective (I..

びまん性血管損傷 磁化率強調画像を用いた重症頭部外傷での収束性出血

INTRODUCTION:Susceptibility-weighted image (SWI) is one of the most sensitive methods for detect microbleeding and useful for evaluation of traumatic brain damage. The purpose of this study is to delineate the characteristics and importance of supratentorial deep white matter hemorrhages detected by SWI in cases of traumatic brain damage. METHODS:Twenty-one consecutive cases with severe traumatic head injury were included in the current study. MRI examinations were made within 1 month after injury. We evaluated the degree and distribution of the supratentorial hemorrhages on SWI retrospectively. We classified the degree of bleeding into four grades: "small hemorrhage," "single bead-like hemorrhage," "convergent-type hemorrhage," and "massive hemorrhage." We then correlated the degree and distribution of the hemorrhage to clinical outcomes. We also evaluated the apparent diffusion coefficient (ADC) image of lobes with "convergent-type hemorrhage." RESULTS:Existence of "massive hemorrhage" correlated with a poor outcome, that is, worse than "severely disabled" on the Glasgow Outcome Scale. The number of lobes affected by "convergent-type hemorrhage" also correlated with poor outcome. There were 45 lobes with "convergent-type hemorrhage" and 27 of them showed increased diffusivity on ADC images. CONCLUSION:Supratentorial massive hemorrhages and supratentorial convergent-type multiple hemorrhages were associated with poor prognosis after traumatic brain injury. The increased diffusivity in lobes with convergent-type hemorrhages may indicate that congestion of the proximal medullary vein may play some role for these hemorrhages.博士（医学）・甲第594号・平成25年3月15日© Springer International Publishing AG,201

DOCK2 is involved in the host genetics and biology of severe COVID-19

「コロナ制圧タスクフォース」COVID-19疾患感受性遺伝子DOCK2の重症化機序を解明 --アジア最大のバイオレポジトリーでCOVID-19の治療標的を発見--. 京都大学プレスリリース. 2022-08-10.Identifying the host genetic factors underlying severe COVID-19 is an emerging challenge. Here we conducted a genome-wide association study (GWAS) involving 2, 393 cases of COVID-19 in a cohort of Japanese individuals collected during the initial waves of the pandemic, with 3, 289 unaffected controls. We identified a variant on chromosome 5 at 5q35 (rs60200309-A), close to the dedicator of cytokinesis 2 gene (DOCK2), which was associated with severe COVID-19 in patients less than 65 years of age. This risk allele was prevalent in East Asian individuals but rare in Europeans, highlighting the value of genome-wide association studies in non-European populations. RNA-sequencing analysis of 473 bulk peripheral blood samples identified decreased expression of DOCK2 associated with the risk allele in these younger patients. DOCK2 expression was suppressed in patients with severe cases of COVID-19. Single-cell RNA-sequencing analysis (n = 61 individuals) identified cell-type-specific downregulation of DOCK2 and a COVID-19-specific decreasing effect of the risk allele on DOCK2 expression in non-classical monocytes. Immunohistochemistry of lung specimens from patients with severe COVID-19 pneumonia showed suppressed DOCK2 expression. Moreover, inhibition of DOCK2 function with CPYPP increased the severity of pneumonia in a Syrian hamster model of SARS-CoV-2 infection, characterized by weight loss, lung oedema, enhanced viral loads, impaired macrophage recruitment and dysregulated type I interferon responses. We conclude that DOCK2 has an important role in the host immune response to SARS-CoV-2 infection and the development of severe COVID-19, and could be further explored as a potential biomarker and/or therapeutic target
