Venous thrombosis is a life-threatening condition with high morbidity and mortality. Abnormal functioning of different cells in the blood is an integral part of its pathogenesis. In this review, we describe the contribution of bone marrow-derived cells to the development of this debilitating disease. We present both epidemiological and clinical data demonstrating involvement of various cell types in venous thrombosis, and discuss potential mechanisms underlying these effects. Modern concepts including recently discovered new paradigms in thrombosis, such as neutrophil extracellular traps, mast cells, and polyphosphate, are summarized.

Food allergy has a known effect on quality of life (QoL), but this has not been extensively studied during the coronavirus disease 2019 pandemic.

To characterize SBI-477 of anxiety of mothers of children aged 0 to 8 years with food allergy compared with families of children without a food allergy and the health-related QoL among children with food allergy during the coronavirus disease 2019 pandemic.

In a mixed-methods study, Canadian mothers of children aged 0 to 8 years with (cases) and without (controls) food allergy provided demographic data and completed age-appropriate anxiety questionnaires between April 14, 2020, and April 28, 2020. The cases also provided food allergy-related data and completed the Food Allergy Quality of Life Questionnaire. In-depth interviews were subsequently conducted with purposefully selected cases.

In a total of 580 participants, 5.5% were cases and 94.5% were controls. For mothers of children aged 0 to 1.5 years, anxiety levels did not differ between cases and controls. #link# For mothers of children aged 1.5 to 8 years, anxiety levels were higher in cases vs controls (P < .05). Among the cases, neither overall nor domain-specific Food Allergy Quality of Life Questionnaire scores differed between age groups (0-3 vs 4-7 years), even after adjustment for confounding variables, including childcare during the pandemic. Qualitatively, the following 3 themes were identified unexpected challenges of food shopping; less food-related food anxiety during the pandemic; and differences and delays in food allergy testing and therapy.

Mothers of children with food allergy reported high anxiety and poor health-related QoL. Yet, qualitatively, day-to-day food allergy management was better during the pandemic.

To synthesize investigations into the role of lipid-mediated recruitment and activation of group 2 innate lymphoid cells (ILC2s) in aspirin-exacerbated respiratory disease (AERD).

A comprehensive literature review of reports pertaining to cellular mechanisms, cytokine, and lipid mediators in AERD, as well as ILC2 activation and recruitment, was performed using PubMed and Google Scholar.

Selections of studies were based on reports of lipid mediators in AERD, cytokine mediators in AERD, type 2 effector cells in AERD, platelets in AERD, AERD treatment, ILC2s in allergic airway disease, and ILC2 activation, inhibition, and trafficking.

The precise mechanisms of AERD pathogenesis are not well understood. Greater levels of proinflammatory lipid mediators and type 2 cytokines are found in tissues derived from patients with AERD relative to controls. After pathognomonic cyclooxygenase-1 inhibitor reactions, proinflammatory mediator concentrations (prostaglandin D2 and cysteinyl leukotrienes) are rapidly increased, as are ILC2 levels in the nasal mucosa. The ILC2s, which potently generate type 2 cytokines in response to lipid mediator stimulation, may play a key role in AERD pathogenesis.

Although the literature suggests that lipid-mediated ILC2 activation may occur in AERD, there is a dearth of definitive evidence. Future investigations leveraging novel next-generation single-cell sequencing approaches along with recently developed AERD murine models will better define lipid mediator-induced ILC2 trafficking in patients with AERD.

Epinephrine autoinjectors (EAs) are the standard of care for severe food allergic reactions, although they are frequently underused or misused.

To understand the factors associated with underuse of EA by caregivers of pediatric patients with food allergy.

A survey was administered to 200 caregivers of pediatric patients with food allergies to assess most severe lifetime allergic reaction, EA education, and use and factors associated with incorrect use or underutilization.

A total of 164 surveys were completed; of which 118 (72%) of lifetime most severe reactions warranted EA use, but the EA was used in only 45 (38.1%). Reasons caregivers indicated for not administering the EA included the following reactions did not seem severe enough; it was the patient's first allergic reaction; use of other medication; and fear of using EA.

Multiple factors contribute to underuse of EA in the treatment of severe allergic reactions. Results from this study highlight the need for continuous EA education in caregivers of and pediatric patients with food allergies, using a multipronged approach targeting clear symptom recognition and alleviation of fear of EA use.

The genus has a long and convoluted taxonomic history, with many attempts made to address the taxonomy and systematics of the group. Here we employ massively parallel sequencing of thousands of ultraconserved elements (UCEs) to provide both the most comprehensive subspecies-level phylogeny of Epinecrophylla antwrens and the first population-level genetic analyses for most species in the genus. Most of our results are robust to a diversity of phylogenetic and population genetic methods, but we show that even with thousands of loci we are unable to fully resolve the relationships between some western Amazonian species in the haematonota group. We uncovered phylogenetic relationships between taxa and patterns of population structure that are discordant with both morphology and current taxonomy. For example, we found deep genetic breaks between taxa in the ornata group that are currently regarded as species, and in the haematonota and leucophthalma groups we found paraphyly at the species and subspecies levels, respectively.
