Rab27b promotes lysosomal function and alpha-synuclein clearance in neurons.

Alpha-synuclein (αsyn) is the key pathogenic protein implicated in synucleinopathies including Parkinson's Disease (PD) and Dementia with Lewy Bodies (DLB). In these diseases, αsyn is thought to spread between cells where it accumulates and induces pathology; however, mechanisms that drive its propagation or aggregation are poorly understood. We have previously reported that the small GTPase Rab27b is elevated in human PD and DLB and that it can mediate the autophagic clearance and toxicity of αsyn in a paracrine αsyn cell culture model.

Parents in peer delivery of family-based behavioral pediatric weight management: the SHIFT randomized noninferiority trial.

Objective: This trial examined the noninferiority of family-based behavioral pediatric weight management treatment (FBT) delivered by peers relative to professionals.

Methods: Children (n = 127) aged 7 to 11 years with BMI > 85th percentile for age and sex and at least one parent with BMI > 25 kg/m were randomly assigned to receive FBT delivered by parents who had previously received FBT from professionals. Child and parent anthropometrics and child quality of life were measured prior to FBT, at treatment end, and at 12-month follow-up.

Co-culture of Helicobacter pylori with oral microorganisms in human saliva.

Objective: Helicobacter pylori is known for colonizing the gastric mucosa and instigating severe upper gastrointestinal diseases such as gastritis, gastroduodenal ulcers, and gastric cancer. To date, there is no data available on the oral cavity as transmission site, whether H. pylori can survive in the oral cavity or in human saliva.

Determining the feasibility of linked claims and vaccination data for a COVID-19 vaccine pharmacoepidemiological study in Germany-RiCO feasibility study protocol.

Introduction: In Germany, there has been no population-level pharmacoepidemiological study on the safety of the COVID-19 vaccines. One factor preventing such a study so far relates to challenges combining the different relevant data bodies on vaccination with suitable outcome data, specifically statutory health insurance claims data. Individual identifiers used across these data bodies are of unknown quality and reliability for data linkage.
