Relationship between phthalates exposures and metabolic dysfunction-associated fatty liver disease in United States adults

by Junhao Sun, Siqi Yang, Yue Zhang, Wenzhi Xiang, Xiubo Jiang

As a new definition for the evidence of hepatic steatosis and metabolic dysfunctions, the relationship between phthalates (PAEs) and metabolic dysfunction-associated fatty liver disease (MAFLD) remains virtually unexplored. This study included 3,137 adults from the National Health and Nutrition Examination Survey spanning 2007–2018. The diagnosis of MAFLD depended on the US Fatty Liver Index (US FLI) and evidence of metabolic dysregulation. Eleven metabolites of PAEs were included in the study. Poisson regression, restricted cubic spline (RCS), and weighted quantile sum (WQS) regression were used to assess the associations between phthalate metabolites and MAFLD. After adjusting for potential confounders, Poisson regression analysis showed that mono-2-ethyl-5-carboxypentyl phthalate (MECPP), mono-n-butyl phthalate, mono-(3-carboxypropyl) phthalate, mono-ethyl phthalate (MEP), mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and mono-(2-ethyl-5-oxohexyl) phthalate were generally significant positively associated with MAFLD (P

Identification of IGF2 promotes skin wound healing by co‐expression analysis

Abstract

Oral mucosa is an ideal model for studying scarless wound healing. Researchers have shown that the key factors which promote scarless wound healing already exist in basal state of oral mucosa. Thus, to identify the other potential factors in basal state of oral mucosa will benefit to skin wound healing. In this study, we identified eight gene modules enriched in wound healing stages of human skin and oral mucosa through co-expression analysis, among which the module M8 was only module enriched in basal state of oral mucosa, indicating that the genes in module M8 may have key factors mediating scarless wound healing. Through bioinformatic analysis of genes in module M8, we found IGF2 may be the key factor mediating scarless wound healing of oral mucosa. Then, we purified IGF2 protein by prokaryotic expression, and we found that IGF2 could promote the proliferation and migration of HaCaT cells. Moreover, IGF2 promoted wound re-epithelialization and accelerated wound healing in a full-thickness skin wound model. Our findings identified IGF2 as a factor to promote skin wound healing which provide a potential target for wound healing therapy in clinic.

Downregulation of the CD151 protects the cardiac function by the crosstalk between the endothelial cells and cardiomyocytes via exosomes

by Luying Jiang, Jingbo Liu, Zhenjia Yang, Jianyu Wang, Wenkai Ke, Kaiyue Zhang, Chunran Zhang, Houjuan Zuo

Background

Heart failure (HF) is the last stage in the progression of various cardiovascular diseases. Although it is documented that CD151 contributes to regulate the myocardial infarction, the function of CD151 on HF and involved mechanisms are still unclear.

Method and results

In the present study, we found that the recombinant adeno-associated virus (rAAV)-mediated endothelial cell-specific knockdown of CD151-transfected mice improved transverse aortic constriction (TAC)-induced cardiac function, attenuated myocardial hypertrophy and fibrosis, and increased coronary perfusion, whereas overexpression of the CD151 protein aggravated cardiac dysfunction and showed the opposite effects. In vitro, the cardiomyocytes hypertrophy induced by PE were significantly improved, while the proliferation and migration of cardiac fibroblasts (CFs) were significantly reduced, when co-cultured with the CD151-silenced endothelial cells (ECs). To further explore the mechanisms, the exosomes from the CD151-silenced ECs were taken by cardiomyocyte (CMs) and CFs, verified the intercellular communication. And the protective effects of CD151-silenced ECs were inhibited when exosome inhibitor (GW4869) was added. Additionally, a quantitative proteomics method was used to identify potential proteins in CD151-silenced EC exosomes. We found that the suppression of CD151 could regulate the PPAR signaling pathway via exosomes.

Conclusion

Our observations suggest that the downregulation of CD151 is an important positive regulator of cardiac function of heart failure, which can regulate exosome-stored proteins to play a role in the cellular interaction on the CMs and CFs. Modulating the exosome levels of ECs by reducing CD151 expression may offer novel therapeutic strategies and targets for HF treatment.

Conducting family meetings on families with dementia: An integrative review

Abstract

Aim

To explore the role of family meetings for individuals living with dementia and their family caregivers.

Design

Integrative review.

Methods

We conducted searches in the Cochrane Library, PubMed, CINAHL, and Embase databases (up to December 2022). Additionally, an ancestry search strategy was employed to supplement the retrieval of published literature related to family meetings or family conferences for people with dementia and their family caregivers.

Results

The review integrated 11 articles, comprising seven quantitative studies, two qualitative studies, and two case reports. The findings did not indicate a significant improvement in end-of-life quality for individuals with dementia in the family meetings group compared to those receiving usual care. Limited evidence suggested some improvement in mental health outcomes for family caregivers. Both intervention and control groups incurred high care costs. However, family meetings appeared to delay nursing home placements for individuals with dementia. Two qualitative studies provided insights into the experiences of families and healthcare professionals participating in family meetings, highlighting opportunities and challenges in implementing such meetings. Additionally, two case reports offered specific and illustrative accounts of typical family meetings.

Conclusion

Family meetings can delay nursing home placements for elderly individuals with dementia. Families dealing with dementia perceive family meetings as an opportunity to collaborate with professionals in providing comprehensive care. Further research is needed to explore the effectiveness of family meetings in decision-making for families affected by dementia. Additionally, addressing timing and process coordination issues in family meetings is crucial for optimising their practices among families dealing with dementia.

Relevance to Clinical Practice

In order to make family meetings more accessible to families of individuals with dementia, we offer the following recommendations for future research and practice: Rather than a blanket rejection, the decision regarding the participation of individuals with dementia in family meetings should be based on their specific condition and the needs of their family. Coordination and harmonisation of opinions and perceptions among family members of individuals with dementia can sometimes be complex for healthcare professionals. The involvement of family coordinators may simplify this process. To determine the optimal timing for holding family meetings that can better assist families dealing with dementia, we propose that the right to initiate a meeting be granted to the family. This allows them to convene with healthcare professionals and address their concerns at their convenience.

Influencing factors of falls among older adults in Chinese retirement institutions: A systematic review and meta-analysis

by Xiaoxing Huang, Yunlan Jiang, Yaxin Liu, Liyin Shen, Jing Pan, Yue Zhang

Background

The incidence of falling has always been high among the elderly, and it was easy to cause injuries to the elderly and seriously affect their quality of life. There were many studies have been conducted on risk factors affecting the fall of the elderly, but the results widely, retirement institutions as a gathering place for the elderly, there was currently no comprehensive analysis of the factors related to elderly falls in pension institutions. This study aimed to explore the influencing factors of falls among older adults in Chinese nursing homes.

Methods

Chinese and English databases were searched for literature published from database inception to 5 April 2023 on the influencing factors of falls among older adults in Chinese nursing homes. Two reviewers independently screened articles, extracted data, and assessed the quality of the included studies. Meta-analysis was performed using RevMan 5.4 software.

Results

Eleven studies involving 3503 participants were included in the meta-analysis. The pooled estimate of falls among older adults in Chinese nursing homes was 32% [95% confidence interval (95%CI) (24.0%, 39.0%)]. The main influencing factors for falls among older adults in Chinese nursing homes were age (Odds Ratio (OR) = 1.53), gender (OR = 5.50), visual impairment (OR = 2.30), sedative-hypnotics (OR = 2.36), fear of falling (OR = 2.95), hypertension (OR = 3.72), static balance (OR = 2.02), three or more chronic diseases (OR = 5.63), cognitive status (OR = 2.64), walking aid use (OR = 1.98), fall-related chronic diseases (OR = 2.48), self-awareness of abilities (OR = 2.43), and frequent reminders for fall prevention (OR = 0.10).

Conclusion

Falls among older adults in Chinese nursing homes were common, and there were many influencing factors. Timely screening and intervention should be implemented to reduce the adverse consequences of falls on older adults.
