Volume-viscosity swallow test to facilitate individualized dietary modifications for dysphagia following intracerebral hemorrhage.

Purpose: This study examined the effects of individualized dietary modifications based on the volume-viscosity swallow test (V-VST) on functional oral intake, incidence of pneumonia, and swallowing-related quality of life in individuals with intracerebral hemorrhage.

Methods: One hundred and seven participants with signs of dysphagia in the acute and early subacute phases of stroke following intracerebral hemorrhage were randomly assigned into an experimental group for individualized dietary modifications based on V-VST plus routine standard care (n = 53), and a control group for routine care alone (n = 54). Incidence of pneumonia, functional oral intake scale (FOIS) ratings and Eating Assessment Tool (EAT-10) scores before and after intervention were evaluated.

An automatic cervical cell classification model based on improved DenseNet121.

The cervical cell classification technique can determine the degree of cellular abnormality and pathological condition, which can help doctors to detect the risk of cervical cancer at an early stage and improve the cure and survival rates of cervical cancer patients. Addressing the issue of low accuracy in cervical cell classification, a deep convolutional neural network A2SDNet121 is proposed. A2SDNet121 takes DenseNet121 as the backbone network.

A novel nomogram for predicting mortality risk in young and middle-aged patients undergoing maintenance hemodialysis: a retrospective study.

Objectives: The annual growth in the population of maintenance hemodialysis (MHD) patients is accompanied by a trend towards younger age groups among new cases.

TGF-β signaling orchestrates cancer-associated fibroblasts in the tumor microenvironment of human hepatocellular carcinoma: unveiling insights and clinical significance.

Liver cancer, specifically hepatocellular carcinoma (HCC), stands out as one of the most formidable solid tumors, characterized by a dauntingly low survival rate. At the forefront of the tumor microenvironment (TME) orchestrating the initiation and advancement of HCC are cancer-associated fibroblasts (CAFs). TGF-β, widely recognized as a potent activator of CAFs, not only regulates their activity but also assumes a pivotal role in the metastatic journey of the tumor.

New insights into interspecies relationships, chromosomal evolution, and hybrid identification in the Lycoris Herb.

Background: Frequent interspecific hybridization, unclear genetic backgrounds, and ambiguous evolutionary relationships within the genus Lycoris pose significant challenges to the identification and classification of hybrids, thereby impacting the application and development of Lycoris. This study utilizes karyotype structure, genome size, and fluorescent in situ hybridization (FISH) technology to explore the chromosomal evolution and hybrid identification of Lycoris employing three approaches at the cytogenetic level.

Results: The findings indicate that species with a smaller basic chromosome number exhibit less asymmetry than those with a larger basic chromosome number, suggesting that species with different basic chromosome numbers may have followed different evolutionary pathways.
