Lung cancer screening by low-dose computed tomography reduces lung cancer mortality, but reliable risk-based selection of participants is crucial to maximize benefits and minimize harms. Multiple risk models have been developed for this purpose, and their discrimination and calibration performance is commonly evaluated based on large-scale cohort studies. Using a recent comparative evaluation of 10 risk models as an example, we illustrate the merits, limitations and pitfalls of such evaluations.

Background: Individuals with diabetes and metabolic syndrome have an increased risk of colorectal cancer (CRC), suggesting earlier screening than the average-risk population may be warranted.

Aims: To derive risk-adapted starting ages of CRC screening for people with diabetes or metabolic syndrome.

Methods: We determined 5-year cumulative risks of CRC at individual ages between 30 and 50 across Europe (overall and individually for Germany, France, the UK and Italy) and North America (the United States and Canada) based on the GLOBOCAN 2022 database.

Article Synopsis
  • * The analysis included 26 studies with variability in sample sizes and methods; 13 studies focused on single metabolites (mostly lipids), while 11 developed panels of metabolites, with two doing both types of assessments.
  • * Metabolite panels, particularly lipid-based ones, show potential for identifying CRC risks, boasting AUC values between 0.69 and 1.0, but their clinical application is hindered by the need for standardization and further validation.*

High red and processed meat intake and genetic predisposition are risk factors of colorectal cancer (CRC). However, evidence of their independent and joint associations on the risk of colorectal neoplasms is limited. We assessed these associations among 4774 men and women undergoing screening colonoscopy.

Article Synopsis
  • - Insufficient physical activity (PA) is a major risk factor for non-communicable diseases and has significant economic impacts on healthcare systems; this study analyzed the cost differences between varying levels of PA in Germany.
  • - Data was collected from over 157,000 participants using the Global Physical Activity Questionnaire to assess their PA levels and categorize them as sufficient or insufficient, with costs calculated from self-reported health resource use and productivity losses.
  • - Findings showed that individuals with insufficient PA incurred higher average annual healthcare costs and that these cost differences were more pronounced in older adults, particularly concerning leisure activities, suggesting different cost implications based on the type of PA.

Introduction: Excess weight is an established risk factor of colorectal cancer (CRC). However, evidence is lacking on how its impact varies by polygenic risk at different stages of colorectal carcinogenesis.

Methods: We assessed the individual and joint associations of body mass index (BMI) and polygenic risk scores (PRSs) with findings of colorectal neoplasms among 4,784 participants of screening colonoscopy.

Background: The present study aimed at the translation and cross-cultural adaptation of six PROMIS pediatric self- and proxy- item banks and short forms to universal German: anxiety (ANX), anger (ANG), depressive symptoms (DEP), Fatigue (FAT), pain interference (P) and peer relationships (PR).

Methods: Using standardized methodology approved by the PROMIS Statistical Center and in line with recommendations of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) PRO Translation Task Force, two translators for each German-speaking country (Germany, Austria, and Switzerland) commented on and rated the translation difficulty and provided forward translations, followed by a review and reconciliation phase. An independent translator performed back translations, which were reviewed and harmonized.

Aim: The increasing body mass index (BMI) often followed by overweight and obesity is a global health problem of the 21st century. Children and adolescents with lower socioeconomic status are more affected than their counterparts. The mechanisms behind these differences must be well understood to develop effective prevention strategies.
