Geophagy is described in most countries of the world as a practice observed in pregnant women. In industrialized countries, it results from migrant populations who carry with them their cultural habits and practices. This is the case in France and more particularly in Guiana, an overseas territory. Originally used to treat the ills of pregnancy, it is today considered to be dangerous for the woman and her unborn child.

Aging is associated with a progressive increase in the incidence of neurodegenerative diseases, both in laboratory animals and humans. In rats, aging is accompanied by degenerative and/or atrophic processes in the cholinergic system of the forebrain, as well as morphological changes which parallel a reduction in spatial learning capacity. 

The emergence of new coronaviruses poses a significant global health threat, as witnessed during recent outbreaks. Coronaviruses were first identified in the 1960s, primarily causing mild respiratory illnesses in humans. The introduction of the severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002, on the other hand, constituted a watershed moment. The outbreak began in China and swiftly spread to numerous nations, resulting in severe respiratory sickness and a global public health disaster. The SARS-CoV outbreak demonstrated coronaviruses' ability to cause severe illness and inspired substantial study into their origins and transmission patterns.

Acute myeloid leukemia (AML) is characterized by multiple molecular and cytogenetic abnormalities, with increasing data to support clinical and prognostic implications to guide clinical decision making. One of the most well described mutations involves fms-like tyrosine kinase 3 (FLT3) that results in a constitutively active tyrosine kinase and is generally associated with poor prognosis involving shorter overall survival and higher rates of relapse.
