A Review of the Knops Blood Group System.

The Knops blood group system is an independent blood group system recognized by International Society of Blood Transfusion (ISBT) in 1992, and latest time consisting of 13 antigens carried on a glycoprotein of 2489 amino acids and called the Complement C3b/C4b Receptor 1 (CR1). Erythrocyte KN antigen was first reported in 1970, and CR1 is a protein coding gene that is a member of the receptors of complement activation (RCA) family and is located in the "cluster RCA" region of chromosome 1. CR1 is an important participant in the erythrocyte immune machinery and plays an major role in inhibiting complement activation, and polymorphisms in its expression have been closely associated with a variety of diseases, including systemic lupus erythematosus (SLE), malaria, Plasmodium falciparum malaria, Alzheimer's disease (AD) and leprosy.

Structural Heart Disease in the Tropics: A Comprehensive Review.

Structural heart disease (SHD) remains a significant global health challenge, disproportionately impacting populations in tropical regions where the burden of infectious diseases, limited healthcare infrastructure, and socio-economic disparities exacerbate the issue. The tropics are uniquely affected by conditions such as rheumatic heart disease (RHD), endomyocardial fibrosis, tropical cardiomyopathies, and pericardial diseases, often resulting from or complicated by endemic infections like malaria, dengue, tuberculosis, and parasitic diseases. Moreover, Human Immunodeficiency Virus-Associated Cardiac Disease (HIVAC) represents an emerging concern in regions with high HIV prevalence, adding complexity to the interplay between infectious and structural cardiac conditions.

Sustainable antimicrobial resistance surveillance: time for a global funding mechanism.

Antimicrobial resistance (AMR) is predicted to outstrip malaria, HIV, and tuberculosis combined as the leading infectious cause of death by 2050. Strengthening the knowledge and evidence base for AMR with surveillance and research is one of the five main objectives of the WHO Global Action Plan on AMR. While recent efforts to strengthen diagnosis and surveillance have been encouraging, these are unlikely to be sustainable without continued funding support in most low-resource settings.
