Multigene panel testing has allowed for the detection of a growing number of inherited pathogenic/likely pathogenic variants in people at high risk of cancer, including endometrial cancer (EC). Hereditary syndromes associated with EC include Lynch syndrome, PTEN hamartoma tumor syndrome, and Peutz-Jeghers syndrome. This manuscript provides the latest recommendations from the NCCN Guidelines for Genetic/Familial High-Risk Assessment: Colorectal, Endometrial, and Gastric on the screening and management of EC in patients at high risk for these syndromes, as well as the advantages and limitations of multigene panel testing.

This study, guided by the theory of planned behavior (TPB), aimed to investigate whether attitude, subjective norms, and perceived behavioral control can predict parents' intentions to reduce or stop adding sugar to their child's beverages, such as tea or milk. The research also seeks to determine the predictive power of the TPB on the actual behavior of parents in reducing or halting sugar intake in their children's drinks. A questionnaire was developed to assess sweetening beverage behavior variables by mothers of children aged 3-7 years attending Lebanese public schools, with 184 responses retained with no missing values for analysis.

Studies of Electronic Nicotine Delivery Systems (ENDS) toxicity have largely focused on individual components such as flavour additives, base e-liquid ingredients (propylene glycol, glycerol), device characteristics (eg, model, components, wattage), use behaviour, etc. However, vaping involves inhalation of chemical mixtures and interactions between compounds can occur that can lead to different toxicities than toxicity of the individual components. Methods based on the additive toxicity of individual chemical components to estimate the health risks of complex mixtures can result in the overestimation or underestimation of exposure risks, since interactions between components are under-investigated.

  • The study aimed to investigate racial disparities in cascade testing rates for genetic predisposition to cancer among at-risk relatives of probands with germline variants.
  • It found that significantly fewer Black probands had their at-risk relatives undergo testing compared to White probands, both before and after a policy change that made testing available at no cost.
  • The disparity in testing rates persisted despite the elimination of testing fees, suggesting that other barriers to testing need to be addressed to improve access and benefits for all populations.
