Primary Cutaneous Anaplastic Large Cell Lymphoma With Rare Extracutaneous Disseminated Disease: A Case Report.

Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a CD30+ lymphoproliferative disorder with generally favorable outcomes and infrequent extracutaneous spread, usually limited to local lymph nodes. However, there may be extensive histologic overlap with more aggressive CD30+ lymphomas, such as large cell transformation of mycosis fungoides or secondary skin involvement by anaplastic lymphoma kinase (ALK)-negative anaplastic large cell lymphoma. Definitive diagnosis relies on clinicopathologic correlation.

Qualitative exploration of the barriers and facilitators to community pharmacy PrEP delivery for UK pharmacists and underserved community members using the COM-B model of behaviour change.

Objectives: Expanding delivery of oral pre-exposure prophylaxis (PrEP) to community pharmacies could improve access, aligning well with the UK government's goals to eliminate new HIV acquisitions by 2030. Using the Capability, Opportunity, Motivation, Behaviour (COM-B) model for behaviour change, the aim of this research was to explore the barriers and facilitators of community pharmacy PrEP delivery, for pharmacists and community members.

Methods: Community members at elevated risk of acquiring HIV and community pharmacists were recruited to participate in semi-structured interviews.

Enabling data linkages for rare diseases in a resilient environment with the SERDIF framework.

Environmental factors amplified by climate change contribute significantly to the global burden of disease, disproportionately impacting vulnerable populations, such as individuals with rare diseases. Researchers require innovative, dynamic data linkage methods to enable the development of risk prediction models, particularly for diseases like vasculitis with unknown aetiology but potential environmental triggers. In response, we present the Semantic Environmental and Rare Disease Data Integration Framework (SERDIF).

Systemic analysis of lipid metabolism from individuals to multi-organism systems.

Lipid metabolism is recognised as being central to growth, disease and health. Lipids, therefore, have an important place in current research on globally significant topics such as food security and biodiversity loss. However, answering questions in these important fields of research requires not only identification and measurement of lipids in a wider variety of sample types than ever before, but also hypothesis-driven analysis of the resulting 'big data'.

Synthesis, characterization, and stability assessment of sodium and barium heptamolybdates.

The study of complex phases in nuclear fuels is necessary to understand the physicochemical properties of the fuel. NaMoO⋅14HO (1) was prepared via a simplified method and the crystal structure was improved. Upon thermal degradation, 1 decomposes into NaMoO and MoO.

Adding "Unlikely" as a Clinical Qualifier Is Unlikely to Be of Help: A Retrospective, Single-Center, Cross-Sectional Cohort Study.

Clinical correlation is essential to accurate and efficient diagnosis and differential diagnosis in dermatopathology. Poor-quality clinical information can lead to failures and delays in patient care. Some clinicians use the term "unlikely" when submitting a specimen.

Motivators, Barriers, and Facilitators to Choosing Care in VA Facilities Versus VA-Purchased Care.

Many Veterans receive Department of Veterans Affairs (VA)-purchased care from non-VA facilities but little is known about factors that Veterans consider for this choice. Between May 2020 and August 2021, we surveyed VA-purchased care-eligible VA patients about barriers and facilitators to choosing where to receive care. We examined the association between travel time to their VA facility and their choice of VA-purchased care (VA-paid health care received in non-VA settings) versus VA facility and whether this association was modified by distrust.

The prescription and monitoring of conventional synthetic disease-modifying anti-rheumatic drugs: British Society for Rheumatology guideline scope.

This guideline will provide up-to-date, evidence-based recommendations on the safe use of non-biologic DMARDs, also called conventional synthetic DMARDs (csDMARD), across the full spectrum of autoimmune rheumatic diseases. The guideline will update the guideline published in 2017 and will be expanded to include people of all ages. Updated information on the monitoring of DMARDs and vaccinations will be included.

Advancing PFAS characterization: Development and optimization of a UV-HO-TOP assay for improved PFCA chain length preservation and organic matter tolerance.

As per- and polyfluoroalkyl substances (PFAS) infiltrate the environment via industrial, commercial, and domestic sources, the demand for robust, cost-effective, and straightforward analytical assays intensifies to enhance PFAS characterization and quantification. To address this demand, this study introduces a novel UV-HO-TOP assay, identifying optimal parameters such as pH (5-9), oxidant concentration (500 mM HO), activation rate (63 mM HO h), and an acceptable total organic carbon (TOC) limit (~1000 mg/L TOC) to achieve maximum PFAA precursor conversion. Additional work was performed further optimizing the UV-TOP assay, by confirming its superiority to heat activation, identifying the effectiveness of different persulfate salts, and investigating different concentrations of sodium persulfate and sodium hydroxide at a 1:2.

Growth of Community Outpatient Care in the Veterans Affairs System After the MISSION Act.

Background: The Maintaining Internal Systems and Strengthening Integrated Outside Networks (MISSION) Act of 2018 authorized a major expansion of purchased care in the community for Veterans experiencing access barriers in the Veterans Affairs (VA) health care system.

Objective: To estimate changes in primary care, mental health, and emergency/urgent care visits in the VA and community fiscal years (FY) 2018-2021 and differences between rural and urban clinics.

Design: A national, longitudinal study of VA clinics and outpatient utilization.

Pediatric Acne Vulgaris: A Guide for Recognition, Examination, Referral, and Treatment.

Acne is a common skin condition in adolescent patients but much less common in childhood. Pediatric providers should be familiar with the varying presentations in the pediatric population and recognize when additional physical signs of hyperandrogenism are present. This article details the pathogenesis and presentation of acne in infancy, mid-childhood, and preadolescence.

The Clinical Resource Hub Telehealth Program and Use of Primary Care, Emergency, and Inpatient Care During the COVID-19 Pandemic.

Background: The COVID-19 pandemic disrupted delivery of health care services worldwide. We examined the impact of the pandemic on clinics participating in the Veterans Affairs (VA) Clinical Resource Hub (CRH) program, rolled out nationally in October 2019, to improve access to care at under-resourced VA clinics or "spoke" sites through telehealth services delivered by regional "hub" sites.

Objective: To assess whether the CRH program was associated with increased access to primary care, we compared use of primary, emergency, and inpatient care at sites that adopted CRH for primary care (CRH-PC) with sites that did not adopt CRH-PC, pre-post pandemic onset.

Mouthparts of the bumblebee () exhibit poor acuity for the detection of pesticides in nectar.

Bees are important pollinators of agricultural crops, but their populations are at risk when pesticides are used. One of the largest risks bees face is poisoning of floral nectar and pollen by insecticides. Studies of bee detection of neonicotinoids have reported contradictory evidence about whether bees can taste these pesticides in sucrose solutions and hence avoid them.

Improving detection of cystic fibrosis related liver disease using liver fibrosis assessment tools.

Background & Aims: Cystic Fibrosis related liver disease (CFLD) is the 3rd largest cause of death in Cystic Fibrosis (CF). As advances in pulmonary therapies have increased life-expectancy, CFLD has become more prevalent. Current guidelines may underdiagnose liver fibrosis, particularly in its early stages.

Advancing PFAS characterization: Enhancing the total oxidizable precursor assay with improved sample processing and UV activation.

Per- and polyfluoroalkyl substances (PFAS) encompass over 9000 chemicals utilized in various industrial and commercial applications. However, the quantification of PFAS using standard commercial analytical methods is currently limited to <50 selected compounds. To address this issue, the total oxidizable precursor (TOP) assay was developed, allowing for the oxidative conversion of previously undetectable PFAS precursors into measurable PFAS.

Data quality and patient characteristics in European ANCA-associated vasculitis registries: data retrieval by federated querying.

Objectives: This study aims to describe the data structure and harmonisation process, explore data quality and define characteristics, treatment, and outcomes of patients across six federated antineutrophil cytoplasmic antibody-associated vasculitis (AAV) registries.

Methods: Through creation of the vasculitis-specific Findable, Accessible, Interoperable, Reusable, VASCulitis ontology, we harmonised the registries and enabled semantic interoperability. We assessed data quality across the domains of uniqueness, consistency, completeness and correctness.

Human equivalent doses of L-DOPA rescues retinal morphology and visual function in a murine model of albinism.

L-DOPA is deficient in the developing albino eye, resulting in abnormalities of retinal development and visual impairment. Ongoing retinal development after birth has also been demonstrated in the developing albino eye offering a potential therapeutic window in humans. To study whether human equivalent doses of L-DOPA/Carbidopa administered during the crucial postnatal period of neuroplasticity can rescue visual function, OCA C57BL/6 J-c2J OCA1 mice were treated with a 28-day course of oral L-DOPA/Carbidopa at 3 different doses from 15 to 43 days postnatal age (PNA) and for 3 different lengths of treatment, to identify optimum dosage and treatment length.

Effects of elexacaftor/tezacaftor/ivacaftor on liver fibrosis markers in adults with cystic fibrosis.

Background: There are limited studies to date on the effects of elexacaftor/tezacaftor/ivacaftor (E/T/I) on markers of liver fibrosis in adults with cystic fibrosis (CF). This study aims to analyse changes in makers of liver fibrosis before and after initiation of E/T/I in CF adults.

Methods: Outcome measures of liver fibrosis, including liver stiffness measurement (LSM) using FibroScan, AST-to-platelet-ratio index (APRI) and gamma-GT-to-platelet-ratio (GPR) were available in 74 CF adults following initiation of E/T/I.
