Disparities in PrEP use and unmet need across PEPFAR-supported programs: doubling down on prevention to put people first and end AIDS as a public health threat by 2030.

Background: In 2023, an estimated 1.3 million people newly acquired HIV. In the same year, 3.

T-bet suppresses proliferation of malignant B cells in chronic lymphocytic leukemia.

The T-box transcription factor T-bet is known as a master regulator of the T-cell response but its role in malignant B cells has not been sufficiently explored. Here, we conducted single-cell resolved multi-omics analyses of malignant B cells from patients with chronic lymphocytic leukemia (CLL) and studied a CLL mouse model with a genetic knockout of Tbx21. We found that T-bet acts as a tumor suppressor in malignant B cells by decreasing their proliferation rate.

Common genetic risk for Parkinson's disease and dysfunction of the endo-lysosomal system.

Parkinson's disease is a progressive neurological disorder, characterized by prominent movement dysfunction. The past two decades have seen a rapid expansion of our understanding of the genetic basis of Parkinson's, initially through the identification of monogenic forms and, more recently, through genome-wide association studies identifying common risk variants. Intriguingly, a number of cellular pathways have emerged from these analysis as playing central roles in the aetiopathogenesis of Parkinson's.

A Novel Variant in the WRN Gene Detected in a Case of Early-Onset Severe Insulin Resistance Displaying Some but Not All Hallmarks of Progeroid Werner Syndrome.

Objective: Determining the cause of severe insulin resistance and early-onset diabetes in the case of a young woman in which a wide range of differential diagnoses did not apply.

Research Design And Methods: Diagnostic workup including medical history, physical examination, specialist consultations, imaging methods, laboratory assessment, and genetic testing carried out by next-generation panel sequencing.

Results: After ruling out several differential diagnoses, genetic testing revealed a previously unknown homozygous variant within the canonical splice site of intron 4 in the WRN gene classified as pathogenic.

Cost-effectiveness analysis of full versus selective root canal retreatment.

Aim: Selective root-canal retreatment has been proposed as an alternative to full retreatment in multirooted, root-canal-filled teeth with evidence of apical pathology, where only the affected root(s) is retreated. Whilst this option may save costs initially, failures and retreatments may compensate for these initial savings. We assessed the cost-effectiveness of full versus selective root-canal retreatment using data from a recent clinical pilot study, employing a modelling approach.
