Covalent Attachment of Horseradish Peroxidase to Single-Walled Carbon Nanotubes for Hydrogen Peroxide Detection.

Single-walled carbon nanotubes (SWCNTs) are desirable nanoparticles for sensing biological analytes due to their photostability and intrinsic near-infrared fluorescence. Previous strategies for generating SWCNT nanosensors have leveraged nonspecific adsorption of sensing modalities to the hydrophobic SWCNT surface that often require engineering new molecular recognition elements. An attractive alternate strategy is to leverage pre-existing molecular recognition of proteins for analyte specificity, yet attaching proteins to SWCNT for nanosensor generation remains challenging.

Weight management medications for chronic use in 37 veterans affairs medical centers-A medication use evaluation.

Rationale: Controlled trials have demonstrated successful weight loss associated with certain weight management medications (WMMs). However, there are limited real-world data on prescribing patterns and efficacy and safety profiles of WMMs in Veterans Affairs (VA) patients.

Objective: To evaluate: utilization patterns of WMMs liraglutide, naltrexone/bupropion, orlistat, phentermine, phentermine/topiramate, and semaglutide; weight loss at three, six, twelve, and more than 12 months; safety; and treatment barriers.

Antibiotic stewardship in the emergency department setting: Focus on oral antibiotic selection for adults with skin and soft tissue infections.

Purpose: An advisory panel of experts was convened by the ASHP Foundation as a part of its Medication-Use Evaluation Resources initiative to provide commentary on an approach to antibiotic stewardship in the treatment of skin and soft tissue infections (SSTIs), with a focus on oral antibiotics in the emergency department (ED) setting for patients who will be treated as outpatients. Considerations include a need to update existing guidelines to reflect new antibiotics and susceptibility patterns, patient-specific criteria impacting antibiotic selection, and logistics unique to the ED setting.

Summary: While national guidelines serve as the gold standard on which to base SSTI treatment decisions, our advisory panel stressed that institutional guidelines must be regularly updated and grounded in local antimicrobial resistance patterns, patient-specific factors, and logistical considerations.

VA Big Data Science: A Model for Improved National Pandemic Response Present and Future.

Background: The US Department of Veterans Affairs (VA) enterprise approach to research (VA Research) has built a data-sharing framework available to all research teams within VA. Combined with robust analytic systems and tools available for investigators, VA Research has produced actionable results during the COVID-19 pandemic. Big data science techniques applied to VA's health care data demonstrate that medical research can be performed quickly and judiciously during nationwide health care emergencies.

Early Mortality After the First Dose of COVID-19 Vaccination: A Target Trial Emulation.

Background: Vaccine hesitancy persists alongside concerns about the safety of coronavirus disease 2019 (COVID-19) vaccines. We aimed to examine the effect of COVID-19 vaccination on risk of death among US veterans.

Methods: We conducted a target trial emulation to estimate and compare risk of death up to 60 days under two COVID-19 vaccination strategies: vaccination within 7 days of enrollment versus no vaccination through follow-up.

Producing knowledge together: a participatory approach to synthesising research across a large-scale collaboration in Aboriginal and Torres Strait Islander health.

Background: Despite that stakeholder participation in evidence synthesis could result in more useful outcomes, there are few examples of processes that actively involve them in synthesis work. Techniques are needed that engage diverse stakeholders as equal partners in knowledge co-production. The aims of this paper are to describe an innovative participatory process of synthesising a large body of academic research products and compare the findings of the participatory process against two traditional approaches to synthesis: a rapid review and a structured review.

Mapping the Morphology of DNA on Carbon Nanotubes in Solution Using X-ray Scattering Interferometry.

Single-walled carbon nanotubes (SWCNTs) with adsorbed single-stranded DNA (ssDNA) are applied as sensors to investigate biological systems, with potential applications ranging from clinical diagnostics to agricultural biotechnology. Unique ssDNA sequences render SWCNTs selectively responsive to target analytes such as (GT)-SWCNTs recognizing the neuromodulator, dopamine. It remains unclear how the ssDNA conformation on the SWCNT surface contributes to functionality, as observations have been limited to computational models or experiments under dehydrated conditions that differ substantially from the aqueous biological environments in which the nanosensors are applied.

Pharmacogenetic testing and monitoring of complete blood counts among Veterans newly prescribed thiopurine treatments: a retrospective cohort study.

Pharmacogenetic (PGx) testing before initiation of thiopurine treatment and CBC monitoring post-initiation helps avoid adverse events and ensure patient safety. This study aims to evaluate trends in PGx testing and CBC monitoring among Veterans prescribed azathioprine, thioguanine, or mercaptopurine to demonstrate VA's efforts to improve medication safety after an adverse event. To assess testing patterns, we used VA electronic health report data to identify 20,524 Veterans who first began thiopurine treatment between January 1, 2010, to December 31, 2021.

ASHP and ASHP Foundation Pharmacy Forecast 2024: Strategic Planning Guidance for Pharmacy Departments in Hospitals and Health Systems.

Purpose: The 2024 ASHP Pharmacy Forecast identifies and contextualizes emerging issues and trends that will influence healthcare, health systems, and the pharmacy profession and provides recommendations to inform long-term strategic planning that should prompt action by pharmacists and health-system leaders.

Methods: Drawing on the “wisdom of crowds” concept, a survey was constructed with 6 general themes, each with 6 to 9 focused statements and a seventh theme on preparedness (58 survey items in total). The size of and representation within the survey panel were intended to capture opinions from a wide range of pharmacy leaders.

Toward robust clinical genome interpretation: Developing a consistent terminology to characterize Mendelian disease-gene relationships-allelic requirement, inheritance modes, and disease mechanisms.

Purpose: The terminology used for gene-disease curation and variant annotation to describe inheritance, allelic requirement, and both sequence and functional consequences of a variant is currently not standardized. There is considerable discrepancy in the literature and across clinical variant reporting in the derivation and application of terms. Here, we standardize the terminology for the characterization of disease-gene relationships to facilitate harmonized global curation and to support variant classification within the ACMG/AMP framework.
