Methotrexate Scarcity Among Children's Oncology Group Institutions: Results of a Multinational Survey.

Shortages of curative chemotherapy agents for children and adults with cancer are ubiquitous. These shortages directly result in compromised outcomes, increased medication errors, heightened cost to health systems, and patient deaths. Methotrexate is a staple of many curative childhood cancer regimens and is frequently in scarcity.

Fingerspelling and Its Role in Translanguaging.

Fingerspelling is a critical component of many sign languages. This manual representation of orthographic code is one key way in which signers engage in translanguaging, drawing from all of their linguistic and semiotic resources to support communication. Translanguaging in bimodal bilinguals is unique because it involves drawing from languages in different modalities, namely a signed language like American Sign Language and a spoken language like English (or its written form).

Evaluation of a retinol containing topical treatment to improve signs of neck aging.

Background: The neck region is an area that can be indicative of signs of skin aging. A novel topical product that combines multiple active ingredients including retinol, tripeptide and glaucine was formulated to specifically target neck aging correction and complement post-procedure as part of an integrated skincare regimen.

Objectives: To evaluate the efficacy of a topical neck treatment through clinical subject evaluation, in addition to ultrasound and biopsy assessment.

Managing Prognosis in Precision Medicine: Utility, Imagination, and Communication.

Research on how physicians predict and communicate prognosis focuses primarily on end-of-life care. Unsurprisingly, as genomic technology gains traction as a prognostic tool, the focus has also been on terminality, with research focused on how genetic results may be used to terminate pregnancies or redirect care towards palliation for neonates. However, genomic results also have powerful impacts on how patients who live prepare for their futures.

An eco-friendly system for stabilization of retinol: A step towards attending performance with improved environmental respect.

Objective: Retinol (Vitamin A) is one of the most effective molecules for the treatment of skin aging. However, it degrades rapidly under the influence of light, oxygen, metal ions, and oxidizing agents. To prevent this, stabilizing systems are used commonly.

Locoregional CAR T cells for children with CNS tumors: Clinical procedure and catheter safety.

Central nervous system (CNS) tumors are the most common solid malignancy in the pediatric population. Based on adoptive cellular therapy's clinical success against childhood leukemia and the preclinical efficacy against pediatric CNS tumors, chimeric antigen receptor (CAR) T cells offer hope of improving outcomes for recurrent tumors and universally fatal diseases such as diffuse intrinsic pontine glioma (DIPG). However, a major obstacle for tumors of the brain and spine is ineffective T cell chemotaxis to disease sites.

Sensitivity to orthographic vs. phonological constraints on word recognition: An ERP study with deaf and hearing readers.

The role of phonology in word recognition has previously been investigated using a masked lexical decision task and transposed letter (TL) nonwords that were either pronounceable (barve) or unpronounceable (brvae). We used event-related potentials (ERPs) to investigate these effects in skilled deaf readers, who may be more sensitive to orthotactic than phonotactic constraints, which are conflated in English. Twenty deaf and twenty hearing adults completed a masked lexical decision task while ERPs were recorded.

What's in a Name? Parents' and Healthcare Professionals' Preferred Terminology for Pathogenic Variants in Childhood Cancer Predisposition Genes.

Current literature/guidelines regarding the most appropriate term to communicate a cancer-related disease-causing germline variant in childhood cancer lack consensus. Guidelines also rarely address preferences of patients/families. We aimed to assess preferences of parents of children with cancer, genetics professionals, and pediatric oncologists towards terminology to describe a disease-causing germline variant in childhood cancer.

Returning a Shelter Dog: The Role of Owner Expectations and Dog Behavior.

Millions of animals are adopted from animal shelters in the United States each year, although some are returned post-adoption, which can decrease both the animals' chances of future adoptions and the owners' willingness to adopt again. In this study, we investigated the impact of adopter expectations for ownership and animal behavioral problems on post-adoptive dog returns at a large animal shelter in South Carolina. Between June-September 2021, 132 dog adopters completed a survey about their expectations for ownership through Qualtrics.

Pediatric Emergency Medicine Didactics and Simulation (PEMDAS) Telesimulation Series: Hyperleukocytosis.

Introduction: Hyperleukocytosis, an infrequent presentation of new-onset leukemia, is a medical emergency requiring prompt recognition and treatment. It can include altered mental status, fever, critical electrolyte derangements, and coagulopathies. Due to the COVID-19 pandemic, this simulation was created as a telesimulation in order to adhere to mandatory physical distancing guidelines while addressing learning objectives.

Are form priming effects phonological or perceptual? Electrophysiological evidence from American Sign Language.

Form priming has been used to identify and demarcate the processes that underlie word and sign recognition. The facilitation that results from the prime and target being related in form is typically interpreted in terms of pre-activation of linguistic representations, with little to no consideration for the potential contributions of increased perceptual overlap between related pairs. Indeed, isolating the contribution of perceptual similarity is impossible in spoken languages; there are no listeners who can perceive speech but have not acquired a sound-based phonological system.

The neurocognitive basis of skilled reading in prelingually and profoundly deaf adults.

Deaf individuals have unique sensory and linguistic experiences that influence how they read and become skilled readers. This review presents our current understanding of the neurocognitive underpinnings of reading skill in deaf adults. Key behavioural and neuroimaging studies are integrated to build a profile of skilled adult deaf readers and to examine how changes in visual attention and reduced access to auditory input and phonology shape how they read both words and sentences.

Cross-linguistic metaphor priming in ASL-English bilinguals: Effects of the Double Mapping Constraint.

Meir's (2010) (DMC) states the use of iconic signs in metaphors is restricted to signs that preserve the structural correspondence between the articulators and the concrete source domain and between the concrete and metaphorical domains. We investigated ASL signers' comprehension of English metaphors whose translations complied with the DMC () or violated the DMC (). Metaphors were preceded by the ASL translation of the English verb, an unrelated sign, or a still video.

The organization of the American Sign Language lexicon: Comparing one- and two-parameter ERP phonological priming effects across tasks.

We used phonological priming and ERPs to investigate the organization of the lexicon in American Sign Language. Across go/no-go repetition detection and semantic categorization tasks, targets in related pairs that shared handshape and location elicited smaller N400s than targets in unrelated pairs, indicative of facilitated processing. Handshape-related targets also elicited smaller N400s than unrelated targets, but only in the repetition task.

Lineage Switch in an Infant B-Lymphoblastic Leukemia With t(1;11)(p32;q23); , Following Blinatumomab Therapy.

We report a 6 month-old infant girl with t(1;11)(p32;q23), -rearranged B-acute lymphoblastic leukemia (B-ALL) that was refractory to traditional ALL-directed chemotherapy. Following administration of blinatumomab, she experienced lineage switch from B-ALL to acute myeloid leukemia (AML). Myeloid-directed chemotherapy resulted in clearance of AML by flow cytometry, though a residual CD19+ B-ALL population persisted (0.

Can a Parent Refuse the Brain Death Examination?

The American Academy of Neurology believes that doctors have the right to do tests to evaluate whether a patient is brain dead even if the family does not consent. They argue that physicians have "both the moral authority and professional responsibility" to do such evaluations, just as they have the authority and responsibility to declare someone dead by circulatory criteria. Not everyone agrees.

ERP Evidence for Co-Activation of English Words during Recognition of American Sign Language Signs.

Event-related potentials (ERPs) were used to investigate co-activation of English words during recognition of American Sign Language (ASL) signs. Deaf and hearing signers viewed pairs of ASL signs and judged their semantic relatedness. Half of the semantically unrelated signs had English translations that shared an orthographic and phonological rime (e.

Phonological and semantic priming in American Sign Language: N300 and N400 effects.

This study investigated the electrophysiological signatures of phonological and semantic priming in American Sign Language (ASL). Deaf signers made semantic relatedness judgments to pairs of ASL signs separated by a 1300 ms prime-target SOA. Phonologically related sign pairs shared two of three phonological parameters (handshape, location, and movement).

Macrophage de novo NAD synthesis specifies immune function in aging and inflammation.

Recent advances highlight a pivotal role for cellular metabolism in programming immune responses. Here, we demonstrate that cell-autonomous generation of nicotinamide adenine dinucleotide (NAD) via the kynurenine pathway (KP) regulates macrophage immune function in aging and inflammation. Isotope tracer studies revealed that macrophage NAD derives substantially from KP metabolism of tryptophan.
