Background: Chronic and/or extreme stress in early life, often referred to as early adversity, childhood trauma, or early life stress, has been associated with a wide range of adverse effects on development. However, while early life stress has been linked to negative effects on a number of neural systems, the specific mechanisms through which early life stress influences development and individual differences in children's outcomes are still not well understood.
Main Text: The current paper reviews the existing literature on the neurobiological effects of early life stress and their ties to children's psychological and behavioral development.
Conclusions: Early life stress has persistent and pervasive effects on prefrontal-hypothalamic-amygdala and dopaminergic circuits that are at least partially mediated by alterations in hypothalamic-pituitary-adrenal axis function. However, to date, this research has primarily utilized methods of assessment that focus solely on children's event exposures. Incorporating assessment of factors that influence children's interpretation of stressors, along with stressful events, has the potential to provide further insight into the mechanisms contributing to individual differences in neurodevelopmental effects of early life stress. This can aid in further elucidating specific mechanisms through which these neurobiological changes influence development and contribute to risk for psychopathology and health disorders.

External Validation of a 5-Factor Risk Model for Breast Cancer-Related Lymphedema.
JAMA Netw Open

Importance: Secondary lymphedema is a common, harmful side effect of breast cancer treatment. Robust risk models that are externally validated are needed to facilitate clinical translation. A published risk model used 5 accessible clinical factors to predict the development of breast cancer-related lymphedema; this model included a patient's mammographic breast density as a novel predictive factor.

Early root traits, particularly total root length, are heritable and show positive genetic correlations with biomass yield in perennial ryegrass; incorporating them into breeding programs can enhance genetic gain. Perennial ryegrass (Lolium perenne L.) is an important forage grass widely used in pastures and lawns, valued for its high nutritive value and environmental benefits.

Background: Colon and rectum cancer (CRC) is a major health burden in China, with notable gender disparities. This study was designed to analyze trends in CRC incidence, prevalence, and mortality from 1990 to 2021 and to project future trends.
Methods: Using data from the Global Burden of Disease (GBD) Study 2021, we examined CRC burden in China, including incidence, prevalence, mortality, disability-adjusted life years (DALYs), years lived with disability (YLDs), and years of life lost (YLLs).

Splenomegaly is a quite common clinical feature of Philadelphia (Ph) negative chronic myeloproliferative neoplasms (MPNs) and its presence may, in some cases, drives treatment decision. Most importantly, palpable splenomegaly is a minor criterion for both pre-fibrotic/early primary myelofibrosis and primary myelofibrosis (PMF) diagnosis, even if clinical assessment by physical examination is poorly reliable and accurate. On the other hand, despite the International Working Group-Myeloproliferative Neoplasms Research and Treatment and European LeukemiaNet guidelines defined spleen response criteria by palpation, they also recognized the highly subjective nature of spleen size assessment by physical examination, and recommended objective confirmation of volume reduction via computed tomography or magnetic resonance imaging (MRI).
