In recent years, the established paradigm of the three Rs of animal research-refinement, replacement, and reduction-has come under scrutiny. A crucial weakness in use of the three Rs is uncertainty about how they should be prioritized. Events like pandemics have the power to alter the research landscape, fast-tracking innovation and setting new precedents. Existential threats can raise perceptions of social benefit and can lower animal-welfare thresholds. The rush to develop new research models may also undermine progress in reducing or replacing animal models...

Point-of-care ultrasound is ubiquitous in the hand of the clinician in many specialties, especially in the evaluation of the patient who is in shock or cardiac arrest. Two of the more common protocols are ACES (Abdominal and Cardiothoracic Evaluation with Sonography) and RUSH (Rapid Ultrasound for Shock and Hypotension). The purpose of this editorial is to introduce a new protocol that builds on many of the previous ones but is more comprehensive and easier to use. The ABCDs of ResUS - Resuscitation Ultrasound - is a systematic head to toe approach to facilitate the workup of the unstable patient...

INTRODUCTION: The literature describes the influence of venom immunotherapy (VIT) on the subpopulation of T regulatory cells (CD4+ CD25+ Foxp3+) and the synthesis of IL-10, TGF-β1 as well as many other cytokines at various times after immunotherapy. AIM: To assess changes in the percentage of cells of CD4+ and CD25+ in peripheral blood and serum concentrations of IL-10, IL-21 and TGF-β1 in the early stages of VIT. MATERIAL AND METHODS: The study included 18 patients who were allergic to wasp venom and who in the past underwent systemic anaphylactic reaction after stinging, meeting the criteria to qualify for VIT...

BACKGROUND: Up to 30% of patients with food allergies have clinical reactivity to more than one food allergen. Although there is currently no cure, oral immunotherapy (OIT) is under investigation. Pilot data have shown that omalizumab may hasten the ability to tolerate over 4 g of food allergen protein. OBJECTIVE: To evaluate the safety and dose tolerability of a Phase 1 Single Site OIT protocol using omalizumab to allow for a faster and safe desensitization to multiple foods simultaneously...

After decades of negative multicenter, randomized, placebo-controlled, double-blind clinical trials in patients with critical illness, the last decade witnessed the publication of a series of studies demonstrating an improved outcome for a variety of interventions. These positive studies and interventions have subsequently been brought together into "bundles" of care. This rush to change clinicians' practice has often been with little regard for the context in which the evidence was generated and the problems created by the difference between efficacy and effectiveness...

High-throughput siRNA screens are now widely used for identifying novel drug targets and mapping disease pathways. Despite their popularity, there remain challenges related to data variability, primarily due to measurement errors, biological variance, uneven transfection efficiency, the efficacy of siRNA sequences, or off-target effects, and consequent high false discovery rates. Data variability can be reduced if siRNA screens are performed in replicate. Running a large-scale siRNA screen in replicate is difficult, however, because of the technical challenges related to automating complicated steps of siRNA transfection, often with multiplexed assay readouts, and controlling environmental humidity during long incubation periods...

BACKGROUND: Studies using rush immunotherapy (RIT) have shown that rapid protection can be achieved using protocols allowing a fast increment of allergen dose. We examined the early effects of RIT on basophil numbers and expression of CD203c, production of interleukin (IL)-4 and IL-13 and histamine release by basophils in the peripheral blood of patients treated with immunotherapy and controls. METHODS: Twelve patients treated with RIT and 4 untreated controls were included in the study...

OBJECTIVE: To establish a focused assessment with sonography for trauma (FAST) protocol in dogs, determine whether FAST can be performed by veterinary clinicians without extensive ultrasonographic experience, and assess the frequency of free fluid (as determined via FAST) in the abdominal cavity of dogs following motor vehicle accidents (MVAs). DESIGN: Prospective study. ANIMALS: 100 client-owned dogs evaluated within 24 hours of an MVA. PROCEDURE: Dogs were placed in lateral recumbency for the FAST examination...

CONTEXT: Although universal screening for diabetes mellitus is generally not recommended, recent reports suggest that screening individuals with multiple diabetes risk factors may be worthwhile. Little is known about the cost, yield, or acceptability of this kind of screening. PRACTICE PATTERN EXAMINED: Screening of high-risk patients for diabetes mellitus using a two-step, glucose-based screening protocol: Patients were initially screened with a random glucose test; those with abnormal results received a follow-up fasting, 2-hour, 75-gram oral glucose tolerance test...

BACKGROUND: Rapid clinical tolerance can be induced over several hours by very fast bee venom immunotherapy (VIT) protocols. OBJECTIVE: To investigate the mechanisms underlying VIT we examined the changes of blood basophil responsiveness during VIT. METHODS: Seven bee venom allergic patients with a history of severe systemic reactions after a bee sting were investigated. A cumulative dose of 111.1 micrograms bee venom (BV) was administered sc over 3...
