Amsterdam UMC, location University of Amsterdam, Department of Global Health, Amsterdam Institute for Global Health and Development, Amsterdam, the Netherlands.
Background: Risk prediction tools for acutely ill children have been developed in high- and low-income settings, but few are validated or incorporated into clinical guidelines. We aimed to assess the performance of existing paediatric early warning scores for use in low- and middle-income countries using clinical data from a recent large multi-country study in Africa and South-Asia.
Methods: We used data (children across three nutritional strata) from the Childhood Acute Illness and Nutrition (CHAIN) Network cohort study (n = 3101).
Propionylation of Fis K32 in serovar Typhi: a key modification affecting pathogenicity.
Future Microbiol
January 2025
Department of Biochemistry & Molecular Biology, School of Medicine, Jiangsu University, Zhenjiang, Jiangsu, China.
Aim: This study aims to explore the role of propionylation at the K32 residue of the global regulator Fis in serovar Typhi (. Typhi) and its influence on the pathogenicity of the bacteria.
Materials & Methods: Bacterial strains were cultured in media with sodium propionate supplementation.
Clinical integration of germline findings from a tumor testing precision medicine program.

Department of Medicine, Division of Medical Oncology and Hematology, Princess Margaret Cancer Centre, University Health Network, University of Toronto, Toronto, ON, Canada.
Background: Integrating germline genetic testing (GGT) recommendations from tumor testing into hereditary cancer clinics and precision oncology trials presents challenges that require multidisciplinary expertise and infrastructure. While there have been advancements in standardizing molecular tumor boards, the implementation of tumor profiling for germline-focused assessments has only recently gained momentum. However, this progress remains inconsistent across institutions, largely owing to a lack of systematic approaches for managing these findings.

Several clinical studies have shown that COVID-19 increases the systemic concentration of drugs in hospitalized patients with COVID-19. However, it is unclear how COVID-19-mediated bidirectional dysregulation of hepatic and pulmonary cytochrome P450 (CYP) 3A4 affects drug concentrations, especially in the lung tissue, which is most affected by the disease. Herein, physiologically based pharmacokinetic modeling was used to demonstrate the differences in systemic and pulmonary concentrations of 4 respiratory infectious disease drugs when CYP3A4 is concurrently downregulated in the liver and upregulated in the lung based on existing clinical data on COVID-19-CYP3A4 interactions at varying severity levels including outpatients, non-intensive care unit (ICU), and ICU patients.

Purpose: To describe the characteristics of sick role adaptation and understand the differences in young and middle-aged colorectal cancer (CRC) patients.
Methods: 225 colorectal cancer patients aged 18-59 admitting to a specialized oncology hospital in Guangzhou, China were involved from January to April 2022. Socio-demographic characteristics, disease-related characteristics, scores of Illness Behavior Questionnaire, Hospital Anxiety and Depression Scale, the Brief Illness Perception Questionnaire, Mishel Uncertainty in Illness Scale and Medical Coping Modes Questionnaire were applied to collect quantitative data.
