Plasmodium vivax is the most prevalent cause of human malaria in the world and can lead to severe disease with high potential for relapse. Its genetic and geographic diversities make it challenging to control. P. vivax is understudied and to achieve control of malaria in endemic areas, a rapid, accurate, and simple diagnostic tool is necessary. In this pilot study, we found that a colorimetric system using AuNPs and MSP10 DNA detection in urine can provide fast, easy, and inexpensive identification of P. vivax. The test exhibited promising sensitivity (84%), high specificity (97%), and only mild cross-reactivity with P. falciparum (21%). It is simple to use, with a visible color change that negates the need for a spectrometer, making it suitable for use in austere conditions. Using urine eliminates the need for finger-prick, increasing both the safety profile and patient acceptance of this model.

Denisovans contributed notably to the genomes of present-day East and Southeast Asians. However, the relationship between the inhabited paleohabitats and the adaptive genetic traits related to infections in modern humans remains underexplored. This study uses geospatial techniques to analyze climatic factors associated with three Denisovan archaeological sites linked to nine specimens.

We hypothesized that variants in inflammasome-related genes could influence susceptibility to gestational malaria (GM). To test this, we conducted an association study in a cohort of pregnant women from a malaria-endemic region in northern Brazil, assessing whether specific functional single nucleotide variants (SNVs) in inflammasome genes affect (1) the response to Plasmodium infection and (2) the development of placental malaria. Our findings revealed that the NLRP1 p.

The global distribution of Plasmodium vivax Circumsporozoite Protein variants (PvCSP), VK210, VK247, and P. vivax-like, plays a crucial role in malaria transmission and vaccine development. This systematic review and meta-analysis assessed the prevalence of these variants in humans and their association with Anopheles species worldwide.

Hepatitis A virus (HAV) typically causes a self-limiting illness in children. Rarely, it can progress to fulminant hepatic failure (FHF), and even less commonly, may be followed by features suggestive of autoimmune hepatitis (AIH). The diagnostic overlap can be particularly challenging in tropical regions, where endemic infections such as dengue and malaria may present with similar clinical features.
