A retrospective examination of quantitation standard growth curves associated with 1,000 unique clinical serum specimens tested by a laboratory-developed TaqMan hepatitis C virus analyte-specific reagent-based assay revealed anomalous growth curves associated with 0.40% (95% confidence interval, 0.11% to 1.00%) of these specimens.

Background: The DCDDaily-questionnaire (DCDDaliy-Q) evaluates children's performance and participation in motor-based activities of daily living (ADLs), meeting diagnostic criterion B for developmental coordination disorder (DCD). Currently, there are no Chinese translations or growth references available. Thus, this study aimed to culturally adapt, validate, and establish reference norms for the DCDDaily-Q in Chinese children.

Background: Thymidine kinases (TKs) are key enzymes involved in DNA synthesis and repair, with alterations in their expression associated with various cancers. Thymidine kinase 1 (TK1) and TK2 are cytosolic enzyme proteins that catalyze the addition of a gamma-phosphate group to thymidine. The existing literature on TK1 in cervical squamous cell carcinoma (CESC) fails to address the clinical role of TK1 overexpression and its possible molecular mechanism in CESC.

Increased nerve density adversely affects outcome in colorectal cancer and denervation suppresses tumor growth.

J Transl Med

Department of Oncology, Shanghai East Hospital, School of Medicine, Tongji University, Shanghai, 200092, P.R. China.

Background: The colon and rectum are highly innervated, with neural components within the tumor microenvironment playing a significant role in colorectal cancer (CRC) progression. While perineural invasion (PNI) is associated with poor prognosis in CRC, the impact of nerve density and diameter on tumor behavior remains unclear. This study aims to evaluate the prognostic value of nerve characteristics in CRC and to verify the impact of nerves on tumor growth.

Background: Child malnutrition remains a critical public health problem, with socioeconomic factors playing a significant role. Socioeconomic factors include household income, parental education, and access to healthcare, which influence a child's nutritional status. Despite overall progress in reducing under-five child malnutrition in Kenya, disparities persist.

Temporal trends and patterns in mortality from falls across 59 high-income and upper-middle-income countries, 1990-2021, with projections up to 2040: a global time-series analysis and modelling study.

Background: Deaths related to falls are a substantial public health problem worldwide, and insight into trends and differences in global fall-related deaths can be valuable for identifying prevention strategies and developing effective policies. Thus, we aimed to estimate global fall-related mortality rate trends and forecast future fall-related deaths.

Methods: In this global time-series analysis and modelling study, we investigated temporal trends in fall-related mortality rates from 1990 to 2021 using the WHO Mortality Database, following the GATHER guidelines, and forecasted trends until 2040 across 59 high-income and upper-middle-income countries.
