Antibody Levels from High-Throughput Variant-Specific SARS-CoV-2 Anti-Spike IgG and ACE2 Neutralization Assays Correlate with COVID Infection Risk in a Large Population.

Background: SARS-CoV-2 antibody levels have been proposed as a correlate of protection (CoP) from infection. Yet, large-scale prospective studies of cost-effective scalable antibody measures as predictors of infection under real-world conditions are limited. We examined whether antibody levels measured using high-throughput variant-specific SARS-CoV-2 anti-spike immunoglobulin G (IgG) and ACE2-neutralization assays correlate with cell-based neutralizing antibody (NAb) measurements, and whether they can serve as a reasonable CoP from SARS-CoV-2 infection.

Genomic surveillance reveals dynamic shifts in the connectivity of COVID-19 epidemics.

The maturation of genomic surveillance in the past decade has enabled tracking of the emergence and spread of epidemics at an unprecedented level. During the COVID-19 pandemic, for example, genomic data revealed that local epidemics varied considerably in the frequency of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) lineage importation and persistence, likely due to a combination of COVID-19 restrictions and changing connectivity. Here, we show that local COVID-19 epidemics are driven by regional transmission, including across international boundaries, but can become increasingly connected to distant locations following the relaxation of public health interventions.

Specialist palliative care out of hours telephone advice in Ireland: a national survey.

Objectives: In 2015 the All-Ireland Institute of Hospice and Palliative Care identified access to specialist palliative care (SPC) advice out of hours (OOH) as their number one research priority. Receiving appropriate advice in response to palliative care needs OOH can address a patient/family's concerns and prevent unnecessary hospital attendances.The aim of this study was to describe the current model of SPC OOH advice in the units that run this service, and gain a greater understanding of the nature of calls received by these services.

Palliative care nursing. Part 1. Building the foundations for primary nursing.

Primary nursing offers a structure that can facilitate the development of patient-centred care and promote the role and status of the nurse. Successful introduction of primary nursing depends on a careful analysis of the current situation, a shared vision for the future, and a consensus on strengths, weaknesses, opportunities and threats. This article explores the experience of four senior nurses who set out to introduce primary nursing to a palliative care setting.
