The assimilation of population models into ecological risk assessment (ERA) has been hindered by their range of complexity, uncertainty, resource investment, and data availability. Likewise, ensuring that the models address risk assessment objectives has been challenging. Recent research efforts have begun to tackle these challenges by creating an integrated modeling framework and decision guide to aid the development of population models with respect to ERA objectives and data availability. In the framework, the trade-offs associated with the generality, realism, and precision of an assessment are used to guide the development of a population model commensurate with the protection goal. The decision guide provides risk assessors with a stepwise process to assist them in developing a conceptual model that is appropriate for the assessment objective and available data. We have merged the decision guide and modeling framework into a comprehensive approach, Population modeling Guidance, Use, Interpretation, and Development for Ecological risk assessment (Pop-GUIDE), for the development of population models for ERA that is applicable across regulatory statutes and assessment objectives. In Phase 1 of Pop-GUIDE, assessors are guided through the trade-offs of ERA generality, realism, and precision, which are translated into model objectives. In Phase 2, available data are assimilated and characterized as general, realistic, and/or precise. Phase 3 provides a series of dichotomous questions to guide development of a conceptual model that matches the complexity and uncertainty appropriate for the assessment that is in concordance with the available data. This phase guides model developers and users to ensure consistency and transparency of the modeling process. We introduce Pop-GUIDE as the most comprehensive guidance for population model development provided to date and demonstrate its use through case studies using fish as an example taxon and the US Federal Insecticide Fungicide and Rodenticide Act and Endangered Species Act as example regulatory statutes.

Aim: Total proctocolectomy (TPC) is the standard of care for patients with ulcerative colitis (UC) and dysplasia not amenable to endoscopic management. However, the risks of an extensive resection may outweigh the benefits in high-risk surgical patients. Therefore, we performed a systematic review and meta-analysis to assess postoperative outcomes between segmental colectomy (SEG) versus TPC in patients with UC.

Purpose: A comprehensive literature review was undertaken to understand the effects and underlying mechanisms of cranial radiotherapy (RT) on the hippocampus and hippocampal neurogenesis as well as to explore protective factors and treatments that might mitigate these effects in preclinical studies.
Methods: PubMed/MEDLINE, Web of Science, and Embase were queried for studies involving the effects of radiation on the hippocampus and hippocampal neurogenesis. Data extraction followed the Animal Research Reporting of In Vivo Experiments (ARRIVE) guidelines, and a risk of bias assessment was conducted for the included animal studies using the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) risk of bias tool.

Chemokine (C-X3-C motif) Receptor 1 (CX3CR1) primarily mediates the chemotaxis and adhesion of immune cells. However, its role in hepatitis C virus (HCV)-induced early-stage liver cirrhosis remains unexplored. GSE15654 was downloaded from the GEO database.

The utility of the sCAR (secrum creatinine/albumin) and LAR (Lactate dehydrogenase/albumin) as diagnostic markers for persistent severe SA-AKI remains unclear.
Methods: We acquired training set data from the MIMIC-IV database and validation set data from the First Affiliated Hospital of Harbin Medical University.

Background: Early identification of the risk of early cancer-related death (within one year, ECRD) due to recurrence after liver resection for hepatocellular carcinoma (HCC) patients with Barcelona Clinic Liver Cancer (BCLC) stage B/C is important for surgeons to make clinical decisions. Our study aimed to establish a nomogram to predict the ECRD due to recurrence for HCC patients with BCLC stage B/C.
Methods: A total of 672 HCC patients with BCLC stages B/C from four medical centers between January 2012 and December 2018 were included in our study.
