Background: Mental health disorders of children and adolescents represent a key area of concern, yet child and adolescent mental health services (CAMHS) are neglected, especially in low- and middle-income countries. There is a clear need to provide services that are relevant to the needs of service users, but little research to date has explored their needs and experiences of services, or to identify their recommendations for service strengthening. In 1997 the South African Government introduced the "Batho Pele" ('People First') initiative in all public sector services, with the aim of putting the voices of service users at the centre of decision-making of policy development and implementation.

Background And Objective: Intravesical instillation of chemotherapy (IIC) after radical surgery for upper urinary tract urothelial carcinoma (UTUC) reduces the risk of intravesical recurrence (IVR). However, compliance is low because of possible extravesical leakage after bladder cuff excision. The aim of this study was to evaluate the efficacy of preoperative IIC in reducing the risk of IVR.

Mosaic loss of Y (mLOY) is the most common somatic chromosomal alteration detected in human blood. The presence of mLOY is associated with altered blood cell counts and increased risk of Alzheimer disease, solid tumors, and other age-related diseases. We sought to gain a better understanding of genetic drivers and associated phenotypes of mLOY through analyses of whole-genome sequencing (WGS) of a large set of genetically diverse males from the Trans-Omics for Precision Medicine (TOPMed) program.

Polygenic risk scores (PRSs) depend on genetic ancestry due to differences in allele frequencies between ancestral populations. This leads to implementation challenges in diverse populations. We propose a framework to calibrate PRS based on ancestral makeup.

Background: Migratory bats perform seasonal movements between their summer and winter areas. When crossing ecological barriers, like the open sea, they are exposed to an increased mortality risk due to energetically demanding long-distance flights and unexpected inclement weather events. How such barriers affect bat migratory movements is still poorly known.
