Hypomethylating agents for patients with VEXAS without myelodysplastic syndrome: Clinical outcome and longitudinal follow-up of vacuolization and UBA1 clonal dynamics.

VEXAS syndrome is a haemato-inflammatory disease caused by somatic UBA1 mutations and characterized by cytoplasmic vacuoles in myeloid and erythroid precursor cells. Although there is currently no standard treatment algorithm for VEXAS, patients are generally treated with anti-inflammatory therapies focused on symptom management, with only partial effectiveness. Hypomethylating agents (HMA) have shown promise in VEXAS patients with concomitant myelodysplastic syndrome (MDS), while the efficacy of HMA in VEXAS patients without MDS is largely unknown.

A "Round, Bruising Sort of Pain": Autistic Girls' Social Camouflaging in Inclusive High School Settings.

Although autistic females often "camouflage" their autism, few studies examine the degree to which adolescent females demonstrate these behaviors in inclusive school settings. We examined: (a) the nature, extent, and underlying motivation of camouflaging in high school; (b) the extent to which autistic girls' characteristics related to camouflaging settings, people, benefits, costs, and school supports; and (c) how girls' open-ended descriptions agreed with closed-ended camouflaging ratings. Using quantitative and qualitative analyses, this study examined the extent, domains, costs, and benefits of autistic females' school-based camouflaging.

Bovine PMN responses to extracellular vesicles released by tachyzoites and -infected host cells.

Bovine besnoitiosis is a re-emerging cattle disease caused by the apicomplexan parasite , which severely affects individual animal welfare and profitability in cattle industry. We recently showed that tachyzoite exposure to bovine polymorphonuclear neutrophils (PMN) effectively triggers neutrophil extracellular trap (NET) formation, leading to parasite immobilization hampering host cell infection. So far, the triggers of this defense mechanism remain unclear.

Catastrophic antiphospholipid syndrome: Lessons from the "CAPS Registry".

The catastrophic antiphospholipid syndrome (CAPS) is a rare life-threatening clinical condition that represents the most severe clinical presentation of the antiphospholipid syndrome (APS). It was first described in 1992 in a group of patients that presented with multiorgan involvement and microangiopathic features of APS. Most of the current knowledge of CAPS comes from the analysis of all cases collected at the "CAPS Registry" that was created in 2000 to perform studies on this condition.

The CAMKK/AMPK Pathway Contributes to -Induced NETosis in Bovine Polymorphonuclear Neutrophils.

is an obligate intracellular apicomplexan parasite and the causal agent of bovine besnoitiosis. Bovine besnoitiosis has a considerable economic impact in Africa and Asia due to reduced milk production, abortions, and bull infertility. In Europe, bovine besnoitiosis is classified as an emerging disease.

A Genome-Wide Association Study Suggests New Susceptibility Loci for Primary Antiphospholipid Syndrome.

Methods: We performed a genome-wide association study comprising 5,485 individuals (482 affected individuals) of European ancestry.

Pathological autoantibody internalisation in myositis.

Objectives: Autoantibodies targeting intracellular proteins are common in various autoimmune diseases. In the context of myositis, the pathologic significance of these autoantibodies has been questioned due to the assumption that autoantibodies cannot enter living muscle cells. This study aims to investigate the validity of this assumption.

Exploring relief for Behçet's disease refractory oral ulcers: a comparison of TNF inhibitors versus apremilast.
