Developing a Nomogram-Based Prediction Model for Malnutrition Risk in Preoperative Elderly Patients with Hip Fracture.

Objective: To evaluate the risk factors contributing to preoperative malnutrition in elderly patients with hip fractures.

Methods: The study retrospectively analysed clinical data from 182 elderly patients aged 60 years or older with hip fractures. Nutritional status was assessed according to the Global Leadership Initiative on Malnutrition diagnostic criteria, and risk factors associated with malnutrition were identified through univariate and logistic regression analyses.

Multiscale Structural Control by Matrix Engineering for Polydimethylsiloxane Filled Graphene Woven Fabric Strain Sensors.

Elastomer cure shrinkage during composite fabrication often induces wrinkling in conductive networks, significantly affecting the performance of flexible strain sensors, yet the specific roles of such wrinkles are not fully understood. Herein, a highly sensitive polydimethylsiloxane-filled graphene woven fabric (PDMS-f-GWF) strain sensor by optimizing the PDMS cure shrinkage through careful adjustment of the base-to-curing-agent ratio is developed. This sensor achieves a gauge factor of ∼700 at 25% strain, which is over 6 times higher than sensors using commercially formulated PDMS.

Association between underlying conditions, multimorbidity, and COVID-19 vaccination status of adults aged ≥80 years old in Beijing, China.

Background: Promoting coronavirus disease 2019 (COVID-19) vaccination is crucial among older adults, particularly those geriatric. This study aimed to analyze the association between chronic conditions, multimorbidity, and vaccination status in adults aged ≥80 years old to provide recommendations for vaccine-preventable diseases.

Methods: A cross-sectional study was conducted in Beijing from April 5, 2023, to May 5, 2023, including participants aged ≥80 years old who did not receive the booster COVID-19 vaccination.

IGF2-IGF1R signaling inhibition delays the growth of IGF2-high colorectal cancer by modulating MDSCs.

Approximately 22 % of human colorectal cancers (CRC) are characterized by IGF2 overexpression, and the tumor-promoting role of IGF2 has been widely reported. Despite promising preclinical results, IGF2 signaling inhibition therapy has exhibited limited efficacy in treating unselected patients with CRC. Recent evidence suggests that IGF2-high CRC are more sensitive to IGF2 signaling blockade therapy in immune-deficient mice, suggesting that IGF2-high CRC can benefit from IGF2 signaling blockade therapy.

Prognostic implications and therapeutic opportunities related to CAF subtypes in CMS4 colorectal cancer: insights from single-cell and bulk transcriptomics.

Cancer-associated fibroblasts (CAFs) significantly influence tumor progression and therapeutic resistance in colorectal cancer (CRC). However, the distributions and functions of CAF subpopulations vary across the four consensus molecular subtypes (CMSs) of CRC. This study performed single-cell RNA and bulk RNA sequencing and revealed that myofibroblast-like CAFs (myCAFs), tumor-like CAFs (tCAFs), inflammatory CAFs (iCAFs), CXCL14CAFs, and MTCAFs are notably enriched in CMS4 compared with other CMSs of CRC.
