The Doppler Perfusion Index of the Liver and the Underlying Duplex Sonography of Visceral Vessels-A Systematic and Comprehensive Evaluation of Reproducibility.

Prior to the curative resection of colorectal carcinoma (CRC) or pancreatic ductal adenocarcinoma (PDAC), the exclusion of hepatic metastasis using cross-sectional imaging is mandatory. The Doppler perfusion index (DPI) of the liver is a promising method for detecting occult liver metastases, but the underlying visceral duplex sonography is critically viewed in terms of its reproducibility. The aim of this study was to investigate systematically the reproducibility of the measured variables, the calculated blood flow, and the DPI.

[The Brandenburg Network Healthy Children: Early Prevention Shows Effectiveness].

Background And Aim Of The Study: The Brandenburg Network Healthy Children (NHC) is a regional health programme for families with toddlers (0-3) run by trained volunteers. Based on the analysis of School Entry Medical Examination (SEME), the study investigates the possible influence of NHC on children's health.

Method: A retrospective epidemiological analysis of the sociodemografic and health-related differences among subgroups nc and n-nc based on SEME, school year 2016/2017 (network children/nc: 1,152, not network children/n-nc: 20,954), using descriptive statistics; a logistic regression analysis assessing, for instance, the power of NHC's influence on health adjusting also for social status and region.
