Life Satisfaction and Its Relationship With Personality Traits Among Medical College Students in China.

BACKGROUND: Life satisfaction is a comprehensive psychological index to measure a person's life quality. Previous studies have found that population sociological factors, physiological factors, psychological factors, and social factors all affect life satisfaction, but few studies have looked at the role of stable psychological factors, such as personality, in life satisfaction. Thus, this study combined previous research results and theories to study the current situation of college students' life satisfaction and its correlation with personality. OBJECTIVE: This study aims to comprehensively assess the life satisfaction levels among university students enrolled in a medical college in China, explore their correlation with various demographic factors and personality traits, identify potential areas for intervention, and provide recommendations for improving students' overall well-being and fostering the development of a positive and healthy personality. METHODS: A stratified cluster sampling method was used to select college students from a university. The questionnaire consists of general characteristics, a life satisfaction scale, and the Big Five Inventory. Descriptive statistical methods were conducted to describe the college students' life satisfaction status; an analysis of variance was performed to compare the score of life satisfaction among different demographic features; and the correlation between the score of life satisfaction and the Big Five Inventory was also analyzed. RESULTS: A total of 3116 subjects were included in this survey. The life satisfaction of females was higher than that of males in the dimensions of family, friends, school, and overall satisfaction (p<0.05). The life satisfaction of males in the self dimension was higher than that of females (p<0.05). The life satisfaction of different weight types had statistical significance in the life dimension (p<0.05). The life satisfaction of family, school, and overall well-being among smoking college students was lower than that of non-smoking college students (p<0.05). The life satisfaction of non-drinking college students in family, friends, life, school, and overall life satisfaction scores was higher than those of drinking college students (p<0.05). College students who get plenty of sleep a day (more than eight hours) scored higher life satisfaction scores in the self dimension than sleep-deprived college students (p<0.05). In addition to the family dimension, students taking long physical exercise breaks every day had higher life satisfaction scores in every dimension than students lacking physical exercise (p<0.05). The mean score of personality in the agreeableness and openness dimensions is the highest. Correlation analysis showed that the personality score in each dimension was positively correlated with the life satisfaction score in each dimension except for the neuroticism dimension of personality (p<0.05). CONCLUSION: The life satisfaction of college students is different for different lifestyles. The student management department should pay attention to the physical and mental health of college students with low life satisfaction and further find out the reasons for the difference in life satisfaction. Meanwhile, education should be strengthened for college students and encourage them to give up smoking and alcohol; strengthen physical training; and university education should strengthen the personality cultivation of college students.

Research Progress of Risk Factors Associated with Gestational Diabetes Mellitus.

Gestational Diabetes Mellitus (GDM) is a common endocrine condition associated with adverse pregnancy outcomes. In recent years, a growing number of risk factors associated with gestational diabetes mellitus have been defined. GDM poses a serious threat to maternal health. The etiology is complex and multifactorial and can be divided into inherent and modifiable factors. The inherent factors have been described in other literature, while the modifiable factors are mainly the risk of lifestyle habits. In this study, we performed a narrative review of the progress of risk factors associated with gestational diabetes mellitus.

Vitamin D May Play a Vital Role in Alleviating Type 2 Diabetes Mellitus by Modulating the Ferroptosis Signaling Pathway.

Ferroptosis is an iron-dependent death mode mediated by the aggregation of lipid peroxides and lipid-reactive oxygen species. It is characterized by iron-dependent lipid peroxide accumulation accompanied by oxidoreductase deficiency. Pancreatic beta cell dysfunction and insulin resistance are two major causes of type 2 diabetes mellitus (T2DM). Iron accumulation and metabolism may play a role in the development of T2DM. The molecular mechanism of ß cell apoptosis and iron death in T2DM were reviewed. In addition, we discuss recent insights on the relationship between the trace element iron and apoptosis of ß cells in T2DM.

Trends and prediction in the incidence rate of hepatitis C in Shandong Province in China from 2004 to 2030.

BACKGROUND: Hepatitis C threatens human health and brings a heavy economic burden. Shandong Province is the second most populous province in China and has uneven regional economic development. Therefore, we analyzed the incidence rate trend and regional differences of hepatitis C in Shandong Province from 2004 to 2021. METHODS: The monthly and annual incidence rates of hepatitis C in Shandong Province from 2022 to 2030 were predicted by fitting Autoregressive Integrated Moving Average model (ARIMA), Long Short-Term Memory (LSTM) and ARIMA-LSTM combined model. RESULTS: From 2004 to 2021, annual new cases of hepatitis C in Shandong Province increased from 635 to 5834, with a total of 61,707 cases. The incidence rate increased from 0.69/100 thousand in 2004 to 6.40/100 thousand in 2019, with a slight decrease in 2020 and 2021. The average annual incidence rate was 3.47/100 thousand. In terms of regional distribution, the hepatitis C incidence rate in Shandong Province was generally high in the west and low in the east. It is estimated that the hepatitis C incidence rate in Shandong Province will be 9.21 per 100 thousand in 2030. CONCLUSION: The hepatitis C incidence rate in Shandong Province showed an increasing trend from 2004 to 2019 and a decreasing trend in 2020 and 2021. Significant regional variations in incidence rate existed. An upward trend in incidence rate is predicted from 2022 to 2030. It is necessary to strengthen the prevention and control of hepatitis C to achieve the goal of eliminating viral hepatitis by 2030.

Engineered elastin-like polypeptide-based hydrogel delivering chemotherapeutics and PD-L1 antibodies for potentiated cancer immunotherapy.

Immune checkpoint inhibitors (ICIs) have effectively eradicated advanced tumors by inducing durable and systematic antitumor immune responses. However, when used as a standalone treatment, ICIs typically exhibit a low response rate in many cancers. In this study, we engineered an in situ-formed gel depot using elastin-like polypeptides (ELPs) to efficiently deliver PD-L1 antibodies (aPD-L1) and gemcitabine (GEM) for enhanced immunotherapy in melanoma. Sustainably released chemotherapeutics from gel depots could kill melanoma cells and promote PD-L1 upregulation in tumor cells. Moreover, aPD-L1/GEM-encapsulated ELP hydrogel promoted a 3.0-fold increase of tumor-infiltrated CD8+ T cells and 60% Tregs depletion compared with PBS group, eliciting a robust antitumor immune response for immunotherapy in melanoma mouse models. This research highlights the promising potential of ELP-based hydrogels in delivering ICIs and chemotherapeutic agents for potentiated cancer immunotherapy.

Exosome-derived long noncoding RNAs: Mediators of host-Plasmodium parasite communication.

Overcoming challenges associated with malaria eradication proves to be a formidable task due to the complicated life cycle exhibited by the malaria parasite and the lack of safe and enduring vaccines against malaria. Investigating the interplay between Plasmodium parasites and their mammalian hosts is crucial for the development of novel vaccines. Long noncoding RNAs (lncRNAs) derived from Plasmodium parasites or host cells have emerged as potential signaling molecules involved in the trafficking of proteins, RNA (mRNAs, miRNAs, and ncRNAs), and DNA. These lncRNAs facilitate the interaction between hosts and parasites, impacting normal physiology or pathology in malaria-infected individuals. Moreover, they possess the capacity to regulate immune responses and associated signaling pathways, thus potentially influencing chromatin organization, epigenetic modifications, mRNA processing, splicing, and translation. However, the functional role of exosomal lncRNAs in malaria remains poorly understood. This review offers a comprehensive analysis of lncRNA and exosomal lncRNA profiles during malaria infection. It presents an overview of recent progress in elucidating the involvement of exosomal lncRNAs in host-parasite interactions. Additionally, potential exosomal lncRNAs linked to the domains of innate and adaptive immunity in the context of malaria are proposed. These findings may contribute to the discovery of new diagnostic and therapeutic strategies for malaria. Furthermore, the need for additional research was highlighted that aimed to elucidate the mechanisms underlying lncRNA transportation into host cells and their targeting of specific genes to regulate the host's immune response. This knowledge gap presents an opportunity for future investigations, offering innovative approaches to enhance malarial control.

OLDER FARMERS OR ILLITERATE OLDER ADULTS ARE MORE LIKELY TO FALL：A COMMUNITY-BASED STUDY FROM CHINA.

The aim of this study was to determine the incidence of falls and its risk factors among community-dwelling older adults in a community from Wuhu city (China). This cross-sectional study recruited 1075 older adults. The history of injury history was assessed in the last year. Descriptive statistics was used for distribution of injury. Risk factors of falls were measured using logistic regression analysis. The results showed that the prevalence of falls in the last year was 8.47%. According to the results, farmer and illiteracy older adults were found as risk factors for falls. In our study, falls were the highest incidence of injury among community-dwelling older adults, farmer and illiteracy older adults were high risk population of falls. Therefore, farmers and illiteracy older adults should be addressed when prevention of falls among community-dwelling older adults.

Essential trace elements in patients with dyslipidemia: A meta-analysis.

BACKGROUND: Lipid metabolism is a complex process that includes lipid uptake, transport, synthesis, and degradation. Trace elements are vital in maintaining normal lipid metabolism in the human body. This study explores the relationship between serum trace elements and lipid metabolism Methods: In this study, we reviewed articles on the relationship between alterations in somatic levels of zinc, iron, calcium, copper, chrome, manganese, selenium, and lipid metabolism. In this systematic review and mate-analysis, databases such as PubMed, Web of Science, and China National Knowledge Infrastructure (CNKI), Wanfang was searched for articles on the relationship published between January 1, 1900, and July 12, 2022. The meta-analysis was performed using Review Manager5.3 (Cochrane Collaboration). RESULTS: No significant association was found between serum zinc and dyslipidemia, while other serum trace elements (Iron, selenium, copper, chromium, and manganese) were associated with hyperlipidemia. CONCLUSION: The present study suggested that the human body's zinc, copper, and calcium content may be related to lipid metabolism. However, findings on lipid metabolism and Iron, Manganese have not been conclusive. In addition, the relationship between lipid metabolism disorders and selenium levels still needs to be further studied. Further research is needed on treating lipid metabolism diseases by changing trace elements.

Role of in vitamin D in irritable bowel syndrome.

Irritable bowel syndrome (IBS) is a common chronic functional gastrointestinal disorder affecting 10%-22% of adults. Its development is closely related to the gut microbiota, and the inflammatory and immune responses triggered by the gut microbiota can lead to IBS. Vitamin D (VD) effectively treats IBS with fewer side effects by improving gut microbiota, immune regulation, and anti-inflammatory effects. In the future, it is necessary to carry out epidemiological studies on the relationship between VD and IBS, clinical studies on the efficacy of supplementing VD to improve IBS, and animal studies on the mechanism of VD improving IBS. Therefore, this paper discussed the relationship between VD and IBS.

Vitamin D may alleviate pre-eclampsia by modulating the ferroptosis signalling pathway: A hypothesis based on recent literature.

Ferroptosis is a novel form of regulated cell death typically characterized by non-apoptotic, iron-dependent, and reactive accumulation of oxygen species. Recent studies have found that ferroptosis plays an important role in the pathophysiology of pre-eclampsia (PE). In order to find potential therapeutic targets for ferroptosis intervention and better prevent the occurrence and progression of PE, the signalling pathways that regulate ferroptosis need to be identified. In this article, we review the role of vitamin D in PE and the role of ferroptosis in PE. Based on recent literature, we propose the scientific hypothesis that vitamin D can alleviate preeclampsia by modulating the ferroptosis signalling pathway. The aim of this review is to understand the regulatory pathways of ferroptosis in PE and to identify potential therapeutic targets.

Context: Researchers have associated insomnia with many disorders, making insomnia a serious public health issue in China. Sleep quality in older adults isn't well characterized in China. Objective: The study intended to explore the sleep quality and subjective duration of sleep in a community-dwelling older population in China and identify potential risk factors for poor sleep. Design: The research team performed a cross-sectional survey using the convenience sampling method. Setting: The study took place in a community in Wuhu, Anhui, China in 2015. Participants: Participants were 1075 members of the community from Wuhu city. Outcome Measures: The research team collected self-reported information on sleep quality. Results: The overall prevalence of self-reported insomnia among older adults were 40.8%. The prevalence of insomnia in females, 259 (59.00%), was significantly higher than in males, 180 (41.00%), with P = .00. For income status, the prevalence of insomnia was significantly higher for participants with less than 10 000 RMB per year income for a family, 191 participants (43.51%), than for participants with higher family incomes, with P = .00. For marital status, the prevalence of insomnia was significantly higher for the widowed participants, 121 participants (24.56%), with P = .01. Conclusions: Sleep quality for females, low-income families, and widowed people were significantly worse than for people in other categories among older adults in China. Older adults in China need proper interventions for the factors causing poor sleep hygiene.

The mediating role of coping strategies between depression and social support and the moderating effect of the parent-child relationship in college students returning to school: During the period of the regular prevention and control of COVID-19.

Objective: According to the WHO, compared to before the COVID-19 pandemic, young people showed a significant increase in depressive symptoms. In light of the recent coronavirus pneumonia pandemic, this study was conducted to determine how social support, coping style, parent-child relationships, and depression are associated. We investigated how these factors interacted and affected the prevalence of depression during this challenging and unheard-of time. Our research may help both individuals and healthcare professionals better comprehend and assist those who are coping with the pandemic's psychological effects. Design and main outcome measures: 3,763 students from a medical college in Anhui Province were investigated with Social Support Rate Scale, Trait Coping Style Questionnaire, and Self-rating Depression Scale. Results: When the pandemic situation was normalizing, social support was associated with depression and the coping style of college students (p < 0.01). During the period of pandemic normalization, the parent-child relationship moderated the relationship between social support and positive coping (t = -2.45, p < 0.05); the parent-child relationship moderated the relationship between social support and negative coping (t = -4.29, p < 0.01); and the parent-child relationship moderated the association between negative coping and depression (t = 2.08, p < 0.05). Conclusion: Social support has an impact on depression in the period of the regular prevention and control of COVID-19 through the mediating role of coping style and the moderating effect of the parent-child relationship.

Narrative review of ferroptosis in obesity.

Obesity is widely recognized as a major global health problem caused by a chronic energy imbalance resulting from a combination of excess caloric intake and insufficient energy expenditure. Excessive energy intake and physical inactivity are traditional risk factors for obesity. Obesity is a risk factor for many diseases, including hypertension, diabetes and tumours. Recent studies have found a strong link between ferroptosis and obesity. Ferroptosis is an iron-dependent regulated cell death caused by iron overload and reactive oxygen species-dependent excessive accumulation of lipid peroxidation. Ferroptosis is involved in many biological processes, such as amino acid metabolism, iron metabolism and lipid metabolism. Some potential strategies to reduce the adverse effects of ferroptosis on obesity are suggested and future research priorities are highlighted.

Trait creativity, personality, and physical activity: a structural equation model.

BACKGROUND: Previous studies have shown that personality affects creativity, and physical activity and is associated with cognitive function. However, the relationship among physical activity, creativity, and personality remains unclear. This study sought to examine the relationship among personality, physical activity, and creativity to identify relevant risk factors of trait creativity. Structural equation modeling (SEM) was used to assess the effect of personality (extraversion, agreeableness, conscientiousness, neuroticism, and openness) on physical activity, the effect of physical activity on creativity traits. METHODS: A total of 296 university students were recruited for this study. The survey was administered by WeChat. The self-reported questionnaires included questions related to demographic information, creativity (from the Williams Creativity Assessment Packet), the Big Five personality traits, and physical activity. A correlation analysis was conducted and the structural equation models were constructed using SPSSAU. RESULTS: The SEM analysis showed that openness in personality was positively correlated with physical activity. Physical activity was negatively correlated with curiosity, challenging, risk-taking, and imagination. CONCLUSIONS: Among university students, openness may be a profound positive factor affecting physical activity. Moreover, physical activity was also associated with trait creativity. Consideration should be given to assessing personality traits and physical activity to ensure the selection of more creative students.
