Global risk of selection and spread of Plasmodium falciparum histidine-rich protein 2 and 3 gene deletions

Since their first detection in 2010, Plasmodium falciparum malaria parasites lacking the P. falciparum histidine-rich protein 2 gene (pfhrp2) have been observed in 40 of 47 surveyed countries, as documented by the World Health Organization. These genetic deletions reduce detection by the most widely used rapid diagnostic tests, prompting three countries to switch to alternative diagnostics.

What goes up must come down: dynamics of type 1 interferon signaling across the lifespan

Type 1 interferons (T1IFNs) are typically expressed in low concentrations under homeostatic conditions, but upon pathogenic insult or perturbation of the pathway, these critical immune signaling molecules can become either protectors from or drivers of pathology. While essential for initiating antiviral defense and modulating inflammation, dysregulation of T1IFN signaling can contribute to immunopathology, making it and its associated pathways prime targets for immune evasion and disruption by pathogens. 

A malaria seasonality dataset for sub-Saharan Africa

Malaria imposes a significant global health burden and remains a major cause of child mortality in sub-Saharan Africa. In many countries, malaria transmission varies seasonally. The use of seasonally-deployed interventions is expanding, and the effectiveness of these control measures hinges on quantitative and geographically-specific characterisations of malaria seasonality.

Prevention of rheumatic heart disease in New Zealand: High-dose subcutaneous benzathine penicillin is cost-saving compared with traditional intramuscular injections

Acute rheumatic fever is a preventable condition that can lead to chronic illness and early death. Standard prevention with 4-weekly intramuscular (IM) benzathine penicillin G (BPG) injections for ≥10 years may be associated with poor adherence. High-dose 10-weekly subcutaneous penicillin injections (SCIP) may improve adherence by reducing injection frequency.

Clonal expansion of new penicillin-resistant clade of neisseria meningitidis serogroup w clonal complex 11, Australia

In Western Australia, Neisseria meningitidis serogroup W clonal complex 11 became the predominant cause of invasive meningococcal disease in 2016

Expression profiling of Sudanese visceral leishmaniasis patients pre- and post-treatment with sodium stibogluconate

These results contribute to our understanding of immunopathology associated with visceral leishmaniasis and response to sodium stibogluconate treatment

Nurses are underutilised in antimicrobial stewardship - Results of a multisite survey in paediatric and adult hospitals

Nurses consider antimicrobial stewardship activities within their roles, but are underutilised in antimicrobial stewardship programs

Using record linkage to validate notification and laboratory data for a more accurate assessment of notifiable infectious diseases

Studies investigating pathogen-specific infectious disease would benefit from using multiple data sources.

Production of IgG antibodies to pneumococcal polysaccharides is associated with expansion of ICOS+ circulating memory T follicular-helper cells which is impaired by HIV infection

Dysfunction of T follicular-helper cells is a possible cause of impaired germinal centre and IgG antibody responses in individuals with HIV
