Estimation of internal displacement in Ukraine from satellite-based car detections.

Estimating the numbers and whereabouts of internally displaced people (IDP) is paramount to providing targeted humanitarian assistance. In conflict settings like the ongoing Russia-Ukraine war, on-the-ground data collection is nevertheless often inadequate to provide accurate and timely information. Satellite imagery may sidestep some of these challenges and enhance our understanding of the IDP dynamics.

Human migration from the Levant and Arabia into Yemen since Last Glacial Maximum.

Newborn Screening for Six Primary Conditions in a Clinical Setting in Morocco.

Unlabelled: Newborn screening (NBS) represents an important public health measure for the early detection of specified disorders; such screening can prevent disability and death, not only from metabolic disorders but also from endocrine, hematologic, immune, and cardiac disorders. Screening for critical congenital conditions affecting newborns' health is a great challenge, especially in developing countries such as Morocco, where NBS program infrastructure is lacking. In addition, the consanguinity rate is high in Morocco.

Targeting GSK-3β for adipose dysfunction and cardiovascular complications of metabolic disease: An entangled WNT/β-catenin question.

Individuals with metabolic syndrome have a high risk of developing cardiovascular disorders that is closely tied to visceral adipose tissue dysfunction, as well as an altered interaction between adipose tissue and the cardiovascular system. In metabolic syndrome, adipose tissue dysfunction is associated with increased hypertrophy, reduced vascularization, and hypoxia of adipocytes, leading to a pro-oxidative and pro-inflammatory environment. Among the pathways regulating adipose tissue homeostasis is the wingless-type mammary tumor virus integration site family (Wnt) signaling pathway, with both its canonical and non-canonical arms.

Pulmonary and Medullary Tuberculosis: An Uncommon Cause of Evans Syndrome in Adults.

Evans syndrome (ES) is a rare syndrome characterised by the association of autoimmune idiopathic hemolytic anemia (AIHA) with immune thrombocytopenia (ITP) and, less commonly, autoimmune neutropenia (AIN). ES may be primary or secondary to some aetiology, including, exceptionally, tuberculosis. We describe a case of association between pulmonary and medullary tuberculosis and Evans syndrome with an effective response to antitubercular treatment and corticosteroids.
