Acute aortic dissection (AAD) is a life-threatening disease with high morbidity and mortality. Previous studies have showed that vascular smooth muscle cell (VSMC) phenotype switching modulates vascular function and AAD progression. However, whether an endogenous signaling system that protects AAD progression exists, remains unknown. Our aim is to investigate the role of Anxa1 in VSMC phenotype switching and the pathogenesis of AAD.

We first assessed Anxa1 expression levels by immunohistochemical staining in control aorta and AAD tissue from mice. A strong increase of Anxa1 expression was seen in the mouse AAD tissues. In line with these findings, micro-CT scan results indicated that Anxa1 plays a role in the development of AAD in our murine model, with systemic deficiency of Anxa1 markedly progressing AAD. Conversely, administration of Anxa1 mimetic peptide, Ac2-26, rescued the AAD phenotype in Anxa1-/- mice. Transcriptomic studies revealed a novel role for Anxa1 in VSMC phenotype switching, with Anxa1 d1 and its mimetic peptide Ac2-26 in AAD through prevention of the switching of VSMC to a synthetic phenotype.
Rituximab (RTX) is an anti-CD20 antibody that selectively depletes B-cells and has emerged as a therapy for ANCA-associated vasculitis (AAV) during the past decade. This study sought to quantify, and determine potential risk factors for, severe infections in AAV patients treated with RTX at rheumatology clinics in Mexico City, Mexico and Lund, Sweden.

The study consisted of a retrospective case-record review (2005-2015) with standardized data collection related to the occurrence of severe infection in 46 patients with AAV in Mexico City (n = 20) and Lund (n = 26) treated with RTX during their disease course. Median duration of follow-up from first RTX dose to death or end of study was 26 months.

Eleven (24%) patients suffered a total of 18 severe infections (infection rate of 11.5/100 patient-years). Thirteen of the 18 infections (72%) occurred within the first year of treatment. check details Risk factors for severe infection were older age at RTX initiation and absence of ENT-involvement at diagnosis. In multivariate analyses, age at RTX infusion was the only independent factor predicting severe infection. Four patients (9%) died during follow-up, all as a result of infection.

Severe infections are common following RTX treatment, and mortality due to infection is a major concern. Most severe infections occur within the first year of RTX treatment. The negative correlation of ENT involvement with severe infection might reflect GPA phenotype heterogeneity. Older age at time of RTX treatment independently predicts severe infections.

The deep gray matter (DGM) exhibits a broad range of pathology and is uniquely suited to study the mechanisms and clinical relevance of tissue injury in MS using magnetic resonance techniques. DGM injury has been associated with clinical and cognitive disability. Recently, MRI characterization of DGM properties, such as thalamic volume, have been tested as potential clinical trial endpoints associated with neurodegenerative aspects of MS. Given this emerging area of interest and its potential clinical trial relevance, the North American Imaging in MS (NAIMS) Cooperative held a workshop and reached consensus on imaging topics related to the DGM. Herein, we review current knowledge regarding DGM injury in MS from an imaging perspective, including insights from histopathology, image acquisition and post-processing for DGM. We discuss the clinical relevance of DGM injury and specific regions of interest within the DGM. We highlight unanswered questions and propose future directions, with the aim of focusing research priorities towards better methods, analysis, and interpretation of results.Evolutionary history, diversity and (paleo)geographic distribution of Cainozoic to present-day species of the Trochidae subfamilies Cantharidinae and Trochinae are discussed based on an extensive literature survey. In total, 393 species-level taxa, assigned to 24 genera and subgenera, are listed from the NE Atlantic, the E Atlantic, the North Sea, the (Proto)-Mediterranean Sea, the Central Paratethys Sea and the Eastern Paratethys Sea. Short diagnosis and subjective and objective junior synonyms for genus-level taxa are given. Stratigraphic ranges and geographic distribution are listed for species-level taxa. The European fossil record suggests a first major radiation during the middle Eocene and a second diversity pulse during the Miocene, when most extant genera were already present. At the species level, however, the present-day fauna is geologically very young, originating during the Pleistocene and Holocene. Overall, no convincing correlation of evolution and diversity of European Cantharidinae and TrochSchaffer, 1912.The Old World genus Mesocomys Cameron (1905) (Hymenoptera Eupelmidae Eupelminae) is revised. Eleven species, including two newly described species, are recognized and keyed in two previously established species groups, the albitarsis and the pulchriceps species groups sensu Gibson (1995), but with additional features provided to distinguish members of the two groups. Five species are recognized in the pulchriceps group-Mesocomys anelliformis n. sp., M. longiscapus n. sp., M. orientalis Ferrière, 1935, M. pauliani Ferrière, 1951, and M. pulchriceps Cameron, 1905. Seven species are assigned to the albitarsis group, but one, M. aegeriae Sheng, 1996 is treated as a nomen dubium; the six recognized and keyed species in the albitarsis group are M. albitarsis (Ashmead, 1904), M. breviscapis Yao, Yang Zhao, 2009, M. menzeli (Ferrière, 1930b), M. obscurus (Ferrière, 1930b) revised stat., M. superansi Yao, Yang Zhao, 2009, and M. trabalae Yao, Yang Zhao, 2009. Within the albitarsis group, the species are further discussed relative to two newly established species subgroups, the albitarsis subgroup for M.
