Potentiating the effect of immunotherapy in pancreatic cancer using gas-entrapping materials.

Immune checkpoint inhibitors (ICIs) show limited success in treating pancreatic ductal adenocarcinoma (PDAC), largely due to immune evasion mechanisms, including downregulating expression of major histocompatibility complex class I (MHC-I). Our retrospective analysis demonstrated that smoking - a state of elevated CO exposure - is correlated with increased MHC I expression in pancreatic tumors. Here we tested our hypothesis that introducing exogenous CO augments the anti-cancer effects of immunotherapy.

A comparison of assessment tools for childcare centers in high vs. low resource settings.

Studies suggest issues may arise when using childcare setting assessment tools designed for high-resource settings in low-resource settings to assess and improve the quality of care, including placing disproportionate weight on features of the childcare environment that may not be available or culturally appropriate within the low-resource context. This study compares a novel assessment tool developed in and for low-income and low-resource settings with a standardized "gold standard" tool developed for use in high-resource settings. The study included a randomized sample of 34 childcare centers in a low-resource context that provided care for approximately 918.

RELAX (REducing Levels of AnXiety): a study protocol for a parallel two-arm randomised controlled trial evaluating a web-based early intervention for pregnant women with high levels of repetitive negative thinking to prevent escalating anxiety during pregnancy and after birth.

Background: Perinatal anxiety is common: up to 40% of pregnant women and new mothers experience high levels of anxiety. Given its prevalence, interventions that are low-intensity, highly accessible and cost-efficient, and target modifiable risk factors for anxiety are needed. Repetitive negative thinking (RNT)-such as worrying about ways things will go wrong in the future or ruminating about past negative events-is a risk factor for the development of anxiety.
