Real-World Treatment Patterns and Healthcare Resource Use for Patients with Myelofibrosis: Results from the METER Study.

Myelofibrosis (MF) is a myeloproliferative neoplasm that was most commonly treated with hydroxyurea (HU) prior to approval of ruxolitinib (RUX), now the standard of care. Factors that influence changes in MF treatment in real-world settings are not well understood. The METER study (NCT05444972) was a multi-country retrospective chart review of MF treatment patterns, treatment effectiveness, and healthcare resource utilization.

Offshore wind and wave energy can reduce total installed capacity required in zero-emissions grids.

As the world races to decarbonize power systems to mitigate climate change, the body of research analyzing paths to zero emissions electricity grids has substantially grown. Although studies typically include commercially available technologies, few of them consider offshore wind and wave energy as contenders in future zero-emissions grids. Here, we model with high geographic resolution both offshore wind and wave energy as independent technologies with the possibility of collocation in a power system capacity expansion model of the Western Interconnection with zero emissions by 2050.

Safety and immunogenicity of the intranasal H3N2 M2-deficient single-replication influenza vaccine alone or coadministered with an inactivated influenza vaccine (Fluzone High-Dose Quadrivalent) in adults aged 65-85 years in the USA: a multicentre, randomised, double-blind, double-dummy, phase 1b trial.

Background: Older adults (aged ≥65 years) show increased susceptibility to severe disease with influenza virus infection, accounting for 70-85% of annual influenza-related fatalities in the USA. Stimulating mucosal antibodies and T cells might enhance the low vaccine effectiveness seen in older adults for currently licensed inactivated influenza vaccines, which induce mainly serum antibodies. We aimed to evaluate the safety and immunogenicity of the intranasal H3N2 M2-deficient single-replication (M2SR) vaccine, alone or coadministered with a licensed inactivated influenza vaccine (Fluzone High-Dose Quadrivalent; hereafter referred to as Fluzone HD), in older adults.

The Growth of Complex Syntax in School-Age African American Children Who Speak African American English.

Purpose: Syntax provides critical support for both academic success and linguistic growth, yet it has not been a focus of language research in school-age African American children. This study examines complex syntax performance of African American children in second through fifth grades.

Method: The current study explores the syntactic performances of African American children ( = 513) in Grades 2-5 on the Test of Language Development-Intermediate who speak African American English.

Active Direction: A new observational measure of African American parenting.

A new observational measure of a culturally salient, supportive African American parenting style, Active Direction, was developed. Ratings were compared to standard qualitative ratings and across two ethnic groups. Active Direction represents the provision of structure to interactions in the form of corrective direction with clear and concise feedback that is assessed for supportiveness rather than simple content or tone.

Long-term administration of intravenous Trappsol® Cyclo™ (HP-β-CD) results in clinical benefits and stabilization or slowing of disease progression in patients with Niemann-Pick disease type C1: Results of an international 48-week Phase I/II trial.

Background: Niemann-Pick disease type C (NPC) is a rare, fatal, pan-ethnic, autosomal recessive lysosomal storage disease characterized by progressive major organ failure and neurodegeneration. Preclinical studies confirmed a critical role of systemically administered hydroxypropyl-β-cyclodextrin (HP-β-CD; Trappsol Cyclo™) in cholesterol metabolism and homeostasis in peripheral tissues of the body, including the liver, and in the central nervous system (CNS). Herein, the pharmacokinetics (PK), safety, and efficacy of HP-β-CD, and biomarkers of NPC were assessed in pediatric and adult patients with NPC1.

EDP-938, a Respiratory Syncytial Virus Inhibitor, in a Human Virus Challenge.

Background: Respiratory syncytial virus (RSV) infection causes substantial morbidity and mortality among infants, older adults, and immunocompromised adults. EDP-938, a nonfusion replication inhibitor of RSV, acts by modulating the viral nucleoprotein.

Methods: In a two-part, phase 2a, randomized, double-blind, placebo-controlled challenge trial, we assigned participants who had been inoculated with RSV-A Memphis 37b to receive EDP-938 or placebo.

Prevention of Respiratory Syncytial Virus Infection in Healthy Adults by a Single Immunization of Ad26.RSV.preF in a Human Challenge Study.

Background: Respiratory syncytial virus (RSV) is a significant cause of severe lower respiratory tract disease in children and older adults, but has no approved vaccine. This study assessed the potential of Ad26.RSV.

Safety and Antiviral Effects of Nebulized PC786 in a Respiratory Syncytial Virus Challenge Study.

Background: PC786 is a nebulized nonnucleoside respiratory syncytial virus (RSV) polymerase inhibitor designed to treat RSV, which replicates in the superficial layer of epithelial cells lining the airways.

Methods: Fifty-six healthy volunteers inoculated with RSV-A (Memphis 37b) were randomly dosed with either nebulized PC786 (5 mg) or placebo, twice daily for 5 days, from either 12 hours after confirmation of RSV infection or 6 days after virus inoculation. Viral load (VL), disease severity, pharmacokinetics, and safety were assessed until discharge.

Functional diversity response to hardwood forest management varies across taxa and spatial scales.

Contemporary forest management offers a trade-off between the potential positive effects of habitat heterogeneity on biodiversity, and the potential harm to mature forest communities caused by habitat loss and perforation of the forest canopy. While the response of taxonomic diversity to forest management has received a great deal of scrutiny, the response of functional diversity is largely unexplored. However, functional diversity may represent a more direct link between biodiversity and ecosystem function.

A Tool for Investigating Asthma and COPD Exacerbations: A Newly Manufactured and Well Characterised GMP Wild-Type Human Rhinovirus for Use in the Human Viral Challenge Model.

Background: Human Rhinovirus infection is an important precursor to asthma and chronic obstructive pulmonary disease exacerbations and the Human Viral Challenge model may provide a powerful tool in studying these and other chronic respiratory diseases. In this study we have reported the production and human characterisation of a new Wild-Type HRV-16 challenge virus produced specifically for this purpose.

Methods And Stock Development: A HRV-16 isolate from an 18 year old experimentally infected healthy female volunteer (University of Virginia Children's Hospital, USA) was obtained with appropriate medical history and consent.

Chemistry and biology of tubulysins: antimitotic tetrapeptides with activity against drug resistant cancers.

Since their first report in 2000, tubulysins have sparked great interest for development as anti-cancer agents due to their exceptionally potent antiproliferative activity. Progress in the discovery and development of tubulysins, especially tubulysin conjugates, has quickly advanced despite limitations in their availability from Nature. In this Highlight, the key research on the isolation and structure determination, biosynthesis, bioactivity, structure-activity relationships (SAR), synthesis, and conjugates of tubulysins is presented.

Broadening the ecological context of ungulate-ecosystem interactions: the importance of space, seasonality, and nitrogen.

Spatial heterogeneity of soil resources, particularly nitrogen availability, affects herbaceous-layer cover and diversity in temperate forest ecosystems. Current hypotheses predict that ungulate herbivores influence nitrogen availability at the stand scale, but how ungulates affect nitrogen availability at finer spatial scales that are relevant to the herb layer is less understood. We tested the hypothesis that ungulate exclusion reduces the spatial complexity of nitrogen availability at neighborhood scales (1-26 m) apart from mean stand scale effects.

Post-disturbance plant community dynamics following a rare natural-origin fire in a Tsuga canadensis forest.

Opportunities to directly study infrequent forest disturbance events often lead to valuable information about vegetation dynamics. In mesic temperate forests of North America, stand-replacing crown fire occurs infrequently, with a return interval of 2000-3000 years. Rare chance events, however, may have profound impacts on the developmental trajectories of forest ecosystems.

Frame-based immobilization and targeting for stereotactic body radiation therapy.

Frame-based stereotactic body radiation therapy (SBRT), such as that conducted with Elekta's Stereotactic Body Frame, can provide an extra measure of precision in the delivery of radiation to extracranial targets, and facilitates secure patient immobilization. In this paper, we review the steps involved in optimal use of an extra-cranial immobilization device for SBRT treatments. Our approach to using frame-based SBRT consists of 4 steps: patient immobilization, tumor and organ motion control, treatment/planning correlation, and daily targeting with pretreatment quality assurance.
