Urinary arsenic species and birth outcomes in Tacna, Peru, 2019: a prospective cohort study.

Arsenic exposure during pregnancy might affect foetal development. Arsenic metabolism may modulate the potential damage to the fetus. Tacna has the highest arsenic exposure levels in Peru.

Systemic biological mechanisms underpin poor post-discharge growth among severely wasted children with HIV.

In sub-Saharan Africa, children with severe malnutrition (SM) and HIV have substantially worse outcomes than children with SM alone, facing higher mortality risk and impaired nutritional recovery post-hospitalisation. Biological mechanisms underpinning this risk remain incompletely understood. This case-control study nested within the CHAIN cohort in Kenya, Uganda, Malawi, and Burkina Faso examined effect of HIV on six months post-discharge growth among children with SM and those at risk of malnutrition, assessed proteomic signatures associated with HIV in these children, and investigated how these systemic processes impact post-discharge growth in children with SM.

VSV drives CD8 T cell-mediated tumour regression through infection of both cancer and non-cancer cells.

Oncolytic viruses (OV) are designed to selectively infect and kill cancer cells, while simultaneously eliciting antitumour immunity. The mechanism is expected to originate from infected cancer cells. However, recent reports of tumour regression unaccompanied by cancer cell infection suggest a more complex mechanism of action.

Colovesical Fistula in a Kidney Transplant Patient: A Fatal Outcome.

Colovesical fistula (CVF) is a rare but potentially serious condition characterized by abnormal communication between the colon and the bladder. This pathology can result from inflammatory diseases, malignancies, or previous surgical interventions, with a significant impact on the patient's quality of life. CVF is associated with high morbidity and mortality rates, particularly in immunosuppressed individuals, such as renal transplant recipients, due to their increased susceptibility to infections and surgical complications.
