Background: Chronic diseases, such as heart disease, cancer, and diabetes, are the leading causes of death and disability. Loneliness is linked to a greater risk of chronic disease. However, the lack of loneliness may change this relationship.

Colorectal polyps serve as potential precursors of colorectal cancer and automating polyp segmentation aids physicians in accurately identifying potential polyp regions, thereby reducing misdiagnoses and missed diagnoses. However, existing models often fall short in accurately segmenting polyps due to the high degree of similarity between polyp regions and surrounding tissue in terms of color, texture, and shape. To address this challenge, this study proposes a novel three-stage polyp segmentation network, named Reverse Attention Feature Purification with Pyramid Vision Transformer (RAFPNet), which adopts an iterative feedback UNet architecture to refine polyp saliency maps for precise segmentation.

Hypertension is a complex disease with unknown causes. Therefore, it's crucial to deeply study its molecular mechanism. The hypertension dataset was obtained from Gene Expression Omnibus data base (GEO), and miRNA regulating central hub genes was screened via weighted gene co-expression network (DEGs) and gene set enrichment (GSEA).

Article Synopsis
  • The study investigates how loneliness affects the risk of cardio-cerebral vascular disease (CCVD) among older Chinese adults aged 62 and older.
  • Researchers analyzed data from over 6,100 participants, scoring their loneliness levels over two years and correlating it with the onset of CCVD a year later.
  • Findings revealed that individuals with a high burden of loneliness had a 37% higher risk of developing CCVD compared to those with lower loneliness scores, suggesting that addressing loneliness could be crucial for improving heart and brain health in older adults.

Background: Chronic stress promotes the development of atherosclerosis, causing disruptions in the body's hormone levels and changes in the structural function of organs.

Objective: The purpose of this study was to investigate the pathological changes in the adrenal gland in a model of atherosclerosis under chronic stress and to verify the expression levels of Sodium-glucose cotransporter (SGLT) 1 and SGLT2 in the adrenal gland and their significance in the changes of adrenal gland.

Methods: The model mice were constructed by chronic unpredictable stress, high-fat diet, and Apoe-/- knockout, and they were tested behaviorally at 0, 4, 8 and 12 weeks.

Parkinson's disease (PD) is a complex progressive neurodegenerative disease associated with aging. Its main pathological feature is the degeneration and loss of dopaminergic neurons related to the misfolding and aggregation of α-synuclein. The pathogenesis of PD has not yet been fully elucidated, and its occurrence and development process are closely related to the microbiota-gut-brain axis.

Article Synopsis
  • Social frailty is less studied compared to physical frailty, especially in relation to cardiovascular and cerebrovascular diseases (CCVD) among older adults in China.
  • A national survey in 2015 included over 222,000 participants aged 60 and older, revealing a 16.03% prevalence of social frailty among those with CCVD, influenced by factors like gender, age, urban-rural location, and education.
  • Key findings indicated that older women with CCVD exhibited higher rates of social frailty, particularly in the 75-79 age group, highlighting regional differences and various health-related issues connected to social frailty.

The WD-repeat (WDR) family affects carcinogenesis, but its role in the immune microenvironment is poorly characterized. Although functional loss or gain of WDR6 does not markedly change in vitro proliferative and invasive capacity of HCC cells, its deficiency in hepa1-6 cells drastically inhibits the growth and lung metastasis of orthotopically implanted tumors in immune-competent C57BL/6J mice. Mechanistically, WDR6 targets tumor suppressor UVRAG to the CUL4A-DDB1-ROC1 E3 ubiquitin ligase complex through a unique WDxR motif and promotes its degradation.

Aim: To evaluated the prevalence and potential risk factors of self-reported diabetes among the elderly in China, by demographic data, socioeconomic factors, and psychological factors.

Methods: Descriptive analysis and Chi-square analysis were used to assess the prevalence and variation between self-reported diabetes and non-diabetes by demographic data, living habits, socioeconomic factors and comorbidities. Univariate and multivariate logistic regression were used to describe the odds ratios (OR) of diabetes prevalence in different groups, while stratification analysis was performed to describe prevalence based on gender, age, and urban/rural areas.

Article Synopsis
  • * Researchers analyzed tumor samples from 50 BC patients alongside normal bladder tissue samples to identify hub genes, finding that six genes (CDK1, TTK, AURKB, MELK, PLK1, and BUB1) were significantly up-regulated in BC.
  • * The study results indicate that higher levels of PLK1 expression correlate with poorer overall survival in BC patients, suggesting it could serve as a potential biomarker for the disease, whereas the other five genes do not show a similar relationship.
