Article Synopsis
- Malaria is a significant global health issue, particularly in Venezuela, where co-infections with other viral and bacterial pathogens complicate malaria diagnosis and treatment, leading to higher mortality rates.
- A study was conducted on 161 malaria patients to assess the prevalence of co-infections with pathogens like dengue virus and hepatitis viruses, using specific laboratory tests for diagnosis.
- Results showed that 34% of the malaria patients had co-infections, with a higher incidence in those infected with the Plasmodium falciparum strain compared to Plasmodium vivax, highlighting the need for improved diagnostic methods in endemic areas.
Background: Venezuela accounted for 55% of the cases and 73% of the malaria deaths in the Americas in 2019. Bolivar state, in the southeast, contributes > 60% of the country's Plasmodium vivax and Plasmodium falciparum cases every year. This study describes the clinical-epidemiological characteristics of clinical malaria patients in this high-transmission area.

- - Pregnant women in southern Venezuela are at a high risk for malaria infections, particularly impacted by the low endemicity of both *Plasmodium falciparum* and *Plasmodium vivax*, but recent studies on malaria in pregnancy (MiP) are lacking in this region.
- - A study analyzing 52 pregnant women at a hospital showed that 71% were infected with *P. vivax*, with most infections occurring in the third trimester; complications were common, including severe anemia and fetal deaths.
- - The findings highlight the need for routine malaria testing and preventive measures, like distributing insecticide-treated mosquito nets, to improve maternal and fetal health in these vulnerable populations.
Oil extraction efficiency strongly depends on the wettability status (oil- vs water-wet) of reservoir rocks during oil recovery. Aromatic compounds with polar functional groups in crude oil have a significant influence on binding hydrophobic molecules to mineral surfaces. Most of these compounds are in the asphaltene fraction of crude oil.

We confirmed this, by using characterization data from an international collection of cocoa, collected 25 years ago, and from a contemporary plantation. We focus on the trees derived from three centuries of admixture between Meso-American Criollo and South American Forastero genomes.
