Wnt signaling is one of the cell's most complex and important signal transduction pathways. This pathway, which is divided into additional sub-pathways, regulates cell growth, motility, polarity, and differentiation during embryonic development as well as stem cell regeneration. In addition, the Wnt cascades are involved in maintaining different aspects of adult homeostasis.

Background: During the COVID-19 pandemic participatory digital surveillance of symptoms (syndromic surveillance) re-established itself as a worthy addition to the surveillance pyramid, as they are scalable, flexible and function independent from the health care system or health care seeking behaviour. A limitation of syndromic surveillance however is the inability of pathogen identification. We describe our experiences regarding integrating self-swabs with centralized testing into a participatory syndromic surveillance system in the Netherlands (Infectieradar).

We conducted the largest genome-wide meta-analysis of borderline personality disorder (BPD) to date, with a discovery sample of 12,339 cases and 1,041,717 controls, and a replication study of 685 cases and 107,750 controls (all participants of European ancestry). We identified 11 independent associated genomic loci, and nine risk genes in the gene-based analysis. We observed a single-nucleotide polymorphism (SNP) heritability of 17.

Background: Vaginitis is a major cause of healthcare visits in the US, costing over $1.2 billion annually. Point-of-care (POC) nucleic acid amplification tests (NAATs) could improve accuracy of diagnosis and treatment during initial visit for vaginitis compared to send-out NAATs.

Background: Peritonsillar abscess (PTA) is a prevalent infection for specialists in otorhinolaryngology and pediatric primary care providers, that has the potential to cause severe complications. The aim of this study is to investigate the surgical treatment of pediatric peritonsillar abscesses and to compare the risk profiles of bilateral surgery versus surgery on the affected side alone. In addition, the evaluation of the microbiological smears obtained intraoperatively should provide information on whether the calculated antibiotic therapy adequately covers the microbial spectrum.
