High-flow nasal cannula versus standard low-flow nasal cannula during deep sedation in patients undergoing radiofrequency atrial fibrillation catheter ablation: a single-centre randomised controlled trial

To our knowledge, there are few trials studying the effect of high-flow nasal cannula (HFNC) during deep sedation. Our hypothesis is that high-flow nasal cannula (HFNC) will prevent hypoxemia and desaturation ...

Clinical Validation of a Novel T-cell Receptor Sequencing Assay for Identification of Recent or Prior SARS-CoV-2 Infection

alexandrossfakianakis shared this article with you from Inoreader
Abstract
Background
While diagnostic, therapeutic, and vaccine development in the COVID-19 pandemic has proceeded at unprecedented speed, critical gaps in our understanding of the immune response to SARS-CoV-2 remain unaddressed by current diagnostic strategies.
Methods
A statistical classifier for identifying prior SARS-CoV-2 infection was trained using >4000 SARS-CoV-2–associated TCRβ sequences identified by comparing 784 cases and 2447 controls from 5 independent cohorts. The T-Detect™ COVID assay applies this classifier to TCR repertoires sequenced from blood samples to yield a binary assessment of past infection. Assay performance was assessed in 2 retrospective (n = 346; n = 69) and 1 prospective cohort (n = 87) to determine positive percent agreement (PPA) and negative percent agreement (NPA). PPA was compared to 2 commercial serology assays, and pathogen cross-reactivity was evaluated.
Results
T-Dete ct COVID demonstrated high PPA in individuals with prior RT-PCR–confirmed SARS-CoV-2 infection (97.1% 15 + days from diagnosis; 94.5% 15 + days from symptom onset), high NPA (∼100%) in presumed or confirmed SARS-CoV-2 negative cases, equivalent or higher PPA than 2 commercial serology tests, and no evidence of pathogen cross-reactivity.
Conclusion
T-Detect COVID is a novel T-cell immunosequencing assay demonstrating high clinical performance for identification of recent or prior SARS-CoV-2 infection from blood samples, with implications for clinical management, risk stratification, surveillance, and understanding protective immunity and long-term sequelae.

Competing responses to global inequalities in access to COVID vaccines: Vaccine Diplomacy and Vaccine Charity Versus Vaccine Liberty

alexandrossfakianakis shared this article with you from Inoreader
Abstract
Global access to COVID vaccines has been extraordinarily unequal and remains an ongoing source of global health insecurities due to the evolution of viral variants in the bodies of the unvaccinated. There have nevertheless been at least three significant alternatives developed to this disastrous bioethical failure. These alternatives are reviewed in this article in the terms of 'vaccine diplomacy', 'vaccine charity', and 'vaccine liberty'. Vaccine diplomacy includes the diverse bilateral deliveries of vaccines organized by the geopolitical considerations of countries strategically seeking various kinds of global and regional advantages in international relations. Vaccine charity centrally involves the humanitarian work of the global health agencies and donor governments that have organized the COVAX program as an antidote to unequal access. Despite their many promises, however, both vaccine diplomacy and vaccine charity have failed to deliver the doses needed to overcome the global vaccination gap. Instead, they have unfortunately served to immunize the global vaccine supply system from more radical demands for a 'People's Vaccine', technological transfer and compulsory licensing of vaccine intellectual property (IP). These more radical demands represent the third alternative to vaccine access inequalities. As a mix of NGO-led and politician-led social justice demands, they are diverse and multifaceted, but together they have been articulated as calls for vaccine liberty. After first describing the realities of vaccine access inequalities, this article compares and contrasts the effectiveness thus far of the three alternatives. In doing so, it also provides a critical bioethical framework for reflecting on how the alternatives have come to compete with one another in the context of the vaccine property norms and market structures entrenched in global IP law. The uneven and limited successes of vaccine dipl omacy and vaccine charity in delivering vaccines in underserved countries can be re-considered in this way as compromised successes that not only compete with one another, but which have also worked together to undermine the promise of universal access through vaccine liberty.

Influence of lingual plate fracture pattern on remodelling site during the healing process of sagittal split ramus osteotomy

alexandrossfakianakis shared this article with you from Inoreader
The purpose of this study was to investigate whether differences in the pattern of the lingual plate split in sagittal split ramus osteotomy (SSRO) affect the remodelling of the split site. Sixty-one patients with mandibular prognathism (122 sides) underwent SSRO. Computed tomography (CT) was performed at 1 week and 1 year after SSRO. Bone splits were classified according to the lingual split scale (LSS) and the lateral bone cut end (LBCE) by evaluating CT images at 1 week. The remodelling at the split sites was evaluated by superimposing the CT images obtained at 1 week and 1 year. (Source: International Journal of Oral and Maxillofacial Surgery)
