Human hemoglobin variants are known to protect the host against severe malaria due to P. falciparum. A new study demonstrates that such genetic variation may also be associated with increased transmission of this pathogen from the human host to the Anopheles vector.

Clinical depression prevalence and associated factors among adolescents with sickle cell anemia in dar es salaam, tanzania: a cross-sectional study.

The Sickle Pan-African Research Consortium (SPARCO) - Tanzania, Muhimbili University of Health and Allied Sciences, Dar Es Salaam, Tanzania.
Background: Depression commonly arises among adolescents who have experienced long-standing psychosocial difficulties, especially those facing chronic illnesses such as sickle cell anemia (SCA). SCA is a global health concern, and Tanzania is one of the countries with a high incidence, estimated at 8,000-11,000 births per year. This study aims to assess the magnitude and factors associated with depression among adolescents with SCA.

Thalassemia is an inherited hematological disorder characterized by a decrease in the synthesis of or absence of one or more globin chains. Hepatitis E virus (HEV) is a major cause of acute viral hepatitis, constituting a major global health burden and emerging as a critical public health concern. HEV infection is mainly transmitted via the fecal-oral route; however, parenteral transmission through blood components has been reported in both developing and developed countries.

The transsulfuration (TSS) pathway is an alternative source of cysteine for glutathione synthesis. Little of the TSS pathway in antioxidant capacity in sickle cell disease (SCD) is known. Here, we evaluate the effects of TSS pathway activation through cystathionine beta-synthase (CBS) to attenuate reactive oxygen species (ROS) and ferroptosis stresses in SCD.

Iron overload has been associated with cerebrovascular disease and cognitive impairment in β-thalassaemia patients, typically appearing earlier than in the general population. However, the mechanisms of iron overload on cerebrovascular pathology remain unclear. This study investigated the effects of heavy iron overload on the blood-brain barrier and neurohistology, particularly in the CA3 region of hippocampus and its contribution to cognitive impairment in β-thalassaemia mice.

This study pursued to evaluate the tropisetron effects in attenuating D-galactose induced heart aging in mice. The study aimed to ascertain whether tropisetron affects apoptotic processes, mitochondrial oxidative stress, or inflammatory variables in cardiac tissue, presumably through the modulation of the SIRT1 signaling pathway or sirtuin 1. Aging was induced via administration of D-galactose (200 mg/kg, s.
