Field testing of recombinant subunit vaccines against in lambing ewes demonstrates a lack of efficacy in the face of a multi-species parasite challenge.

Introduction: We previously demonstrated efficacy of an 8-antigen recombinant subunit vaccine against a single species homologous challenge in lambs and in lambing ewes in pen trials. We subsequently demonstrated efficacy of a simplified, 2-antigen, version of this vaccine in lambs in pen trials. Here, we test both vaccines in lambing ewes in a field setting.

Expanding the Toolbox: A Palliative Care Lecture Series for Oncology Advanced Practice Providers.

Purpose: Initiation of early palliative care (PC) is vital in order to assure that the physical, psychological, spiritual, and social needs of patients and their families are addressed before, during, and after treatment for a serious illness. According to the World Health Organization, PC is patient-and family-centered care that optimizes quality of life by anticipating, preventing, and treating suffering. It is holistic care that addresses the physical, psychosocial, and spiritual needs of patients and their families.

Biophysical mapping of TREM2-ligand interactions reveals shared surfaces for engagement of multiple Alzheimer's disease ligands.

TREM2 is a signaling receptor expressed on microglia that has emerged as an important drug target for Alzheimer's disease and other neurodegenerative diseases. While a number of TREM2 ligands have been identified, little is known regarding the structural details of how they engage. To better understand this, we created a protein library of 28 different TREM2 variants that could be used to map interactions with various ligands using biolayer interferometry.

Using routine primary care data in research: (in)efficient case studies and perspectives from the Asthma UK Centre for Applied Research.

Aim: We aimed to identify enablers and barriers of using primary care routine data for healthcare research, to formulate recommendations for improving efficiency in knowledge discovery.

Background: Data recorded routinely in primary care can be used for estimating the impact of interventions provided within routine care for all people who are clinically eligible. Despite official promotion of 'efficient trial designs', anecdotally researchers in the Asthma UK Centre for Applied Research (AUKCAR) have encountered multiple barriers to accessing and using routine data.

Characteristics and Outcomes of Descemet Membrane Endothelial Keratoplasty for Treatment of Failed Endothelial Keratoplasty.

Purpose: To evaluate Descemet membrane endothelial keratoplasty (DMEK) for failed endothelial keratoplasty (EK).

Methods: We reviewed 362 consecutive DMEK cases for failed EK (Descemet stripping endothelial keratoplasty (DSEK) or DMEK), 118 for early EK failure, and 244 for late failure in 333 eyes of 323 patients without penetrating keratoplasty. Rejection and graft survival rates were assessed with Kaplan-Meier analysis.

The Impact of "Close Margins" in HPV-Associated Oropharyngeal Squamous Cell Carcinoma Treated with TORS.

Objective: Margin distance is a significant prognosticator in oral cavity cancer but its role in HPV-related oropharyngeal squamous cell carcinoma [HPV(+)OPSCC] remains unclear. Here, we investigate the impact of margin distance on locoregional recurrence in HPV(+)OPSCC.

Study Design: This is a retrospective cohort study of surgically treated HPV(+)OPSCC patients.

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Spatiotemporal patterns of mortality events in farmed Atlantic salmon in British Columbia, Canada, using publicly available data.

Monitoring mortality is an essential strategy for fish health management. Commercial marine finfish sites in British Columbia, Canada, are required to report mortality events (MEs) to Fisheries and Oceans Canada (DFO), which makes these data publicly available. This study aimed to analyze the spatial and temporal patterns of ME composition and total MEs.

Inhibitory KIRs decrease HLA class II-mediated protection in Type 1 Diabetes.

Inhibitory killer cell immunoglobulin-like receptors (iKIRs) are a family of inhibitory receptors that are expressed by natural killer (NK) cells and late-stage differentiated T cells. There is accumulating evidence that iKIRs regulate T cell-mediated immunity. Recently, we reported that T cell-mediated control was enhanced by iKIRs in chronic viral infections.

Preserved Ratio Impaired Spirometry in US Primary Care Patients Diagnosed with Chronic Obstructive Pulmonary Disease.

Background: Preserved ratio impaired spirometry (PRISm) represents a population with spirometry results that do not meet standardized COPD obstruction criteria, yet present with high respiratory symptom burden and might benefit from respiratory management and treatment. We aimed to determine prevalence of PRISm in US primary care patients diagnosed with COPD, describe their demographic, clinical, and CT scan characteristics.

Methods: An observational registry study utilizing the US APEX COPD registry, composed of patients diagnosed with COPD aged 35+ years.

National Trends and Benchmarks for Operative Time and Hospital Length of Stay in Parotidectomies.

Objective: The extent of parotidectomy for benign tumors has de-escalated in the United States. We aim to define modern benchmarks for operative time and hospital length of stay (LOS) in parotidectomy and identify risk factors that may prolong these benchmarks.

Study Design: This is a retrospective cross-sectional study of all adults who underwent parotidectomy for a primary parotid neoplasm between January 2011 and December 2021 using the American College of Surgeons National Surgical Quality Improvement Program database.

The impact of 3D real-IR delayed post gadolinium MRI parameterisation on the diagnostic performance and optimal descriptor selection in Ménière's disease.

Objectives: To compare the performance and optimal combination of MRI descriptors used for the diagnosis of Ménière's disease (MD) between a real-IR sequence with "zero-point" endolymph (ZPE), and an optimised real-IR sequence with negative signal endolymph (NSE).

Materials And Methods: This retrospective single-centre cross-sectional study evaluated delayed post-gadolinium ZPE and NSE real-IR MRI in consecutive patients with Ménièriform symptoms (8/2020-10/2023). Two observers assessed 14 MRI descriptors.

Increasing engagement in HIV prevention among cisgender women in New York City with sexual health self-testing kits: A MaxDiff analysis.

Background: Despite accounting for approximately 20% of new HIV diagnoses in the United States, cisgender women are consistently under-represented and under-engaged in HIV prevention services such as HIV testing and pre-exposure prophylaxis (PrEP). Black and Latina cisgender woman (BLCW) are disproportionately impacted by HIV, and face additional barriers to accessing prevention services due to racial/ethnic bias, sexism, and their intersection. Offering self-testing for sexually transmitted infections (STIs) and HIV is one potential strategy for increasing access to-and engagement in-preventative sexual health care among BLCW.

Developmental Coordination Disorder and Early Childhood Trajectories of Physical Activity.
