SARS-CoV-2 hybrid immunity: silver bullet or silver lining?
Suryawanshi Rahul et al. Nature reviews. Immunology 2022 8

Hybrid immunity occurs in those who have been both infected with and vaccinated against SARS-CoV-2. But how well does such hybrid immunity protect against the virus and its emerging variants? Several studies suggest that hybrid immunity confers more effective cross-variant neutralization than a natural infection alone (Fig. 1a,c). Vaccination after infection with the SARS-CoV-2 ancestral Wuhan-Hu-1 strain or with Alpha, Delta and Beta variants increases the number of SARS-CoV-2 memory T cells and B cells by more than an order of magnitude by recruiting new B cell clones into the memory pool and expanding persistent clones.(

Measuring Lipoprotein(a) in Clinical Practice to Reduce the Burden of Cardiovascular Disease? Still Work in Progress.
J Osei et al, CDC Blog Post, August 9, 2022 Brand

A recent review suggested that the use of lipoprotein (Lp) (a) measurement in clinical practice may have clinical and economic benefits for patients, healthcare systems, and society as a whole. However, widespread adoption of Lp(a) measurement in the general population has been hindered by limited treatment options targeting Lp(a) reduction.

Interactive exploration of a global clinical network from a large breast cancer cohort
N Sella et al, NPJ Diital Medicine, August 10, 2022

Despite unprecedented amount of information now available in medical records, health data remain underexploited due to their heterogeneity and complexity. Simple charts and hypothesis-driven statistics can no longer apprehend the content of information-rich clinical data. There is, therefore, a clear need for powerful interactive visualization tools enabling medical practitioners to perceive the patterns and insights gained by state-of-the-art machine learning algorithms. Here, we report an interactive graphical interface for use as the front end of a machine learning causal inference server (MIIC), to facilitate the visualization and comprehension by clinicians of relationships between clinically relevant variables.

Leveraging reimbursement strategies to guide value-based adoption and utilization of medical AI
KP Venkatesh et al, NPJ Digital Medicine, August 10, 2022

With the increasing number of FDA-approved artificial intelligence (AI) systems, the financing of these technologies has become a primary gatekeeper to mass clinical adoption. Reimbursement models adapted for current payment schemes, including per-use rates, are feasible for early AI products. A successful reimbursement strategy will align interests across stakeholders to guide value-based and cost-effective improvements to care.
