Crosstalk between hypoxia-inducible factor-1α and short-chain fatty acids in inflammatory bowel disease: key clues toward unraveling the mystery.

The human intestinal tract constitutes a complex ecosystem, made up of countless gut microbiota, metabolites, and immune cells, with hypoxia being a fundamental environmental characteristic of this ecology. Under normal physiological conditions, a delicate balance exists among these complex "residents", with disruptions potentially leading to inflammatory bowel disease (IBD). The core pathology of IBD features a disrupted intestinal epithelial barrier, alongside evident immune and microecological disturbances. Central to these interconnected networks is hypoxia-inducible factor-1α (HIF-1α), which is a key regulator in gut cells for adapting to hypoxic conditions and maintaining gut homeostasis. Short-chain fatty acids (SCFAs), as pivotal gut metabolites, serve as vital mediators between the host and microbiota, and significantly influence intestinal ecosystem. Recent years have seen a surge in research on the roles and therapeutic potential of HIF-1α and SCFAs in IBD independently, yet reviews on HIF-1α-mediated SCFAs regulation of IBD under hypoxic conditions are scarce. This article summarizes evidence of the interplay and regulatory relationship between SCFAs and HIF-1α in IBD, pivotal for elucidating the disease's pathogenesis and offering promising therapeutic strategies.

The Effect of Bullying Victimization on Adolescent Non-Suicidal Self-Injury: The Mediating Roles of Alexithymia and Self-Esteem.

Background & Aim: Non-suicidal self-injury (NSSI) in adolescents is a serious public health issue influenced by the interaction of multiple factors. The purpose of this study was to investigate the multiple mediating roles of alexithymia and self-esteem in the association between bullying victimization and NSSI in a sample of Chinese adolescents. Methods: A survey of 1299 adolescents from two public middle schools in Henan Province, China, was undertaken. Data were collected using the Chinese version of the Delaware bullying victimization scale-student (DBVS-S), the Toronto Alexithymia-20 Scale (TAS-20-C), the Rosenberg self-esteem scale (RSES), and the adolescent self-injury questionnaire. Besides, we performed a structural equation modeling (SEM) with latent variables using AMOS 26.0 to examine the relationship between variables and the mediating effects. Results: The SEM analysis found that not only can bullying victimization directly impact NSSI, but that alexithymia and self-esteem have a chain mediating effect in the association between bullying victimization and NSSI. This mediating effect contributed 22.47% to the total effect. Conclusion: These findings validate bullying victimization, alexithymia, and low self-esteem are important variables that affect NSSI among Chinese adolescents. Educators need to implement some prevention and intervention strategies to ameliorate the campus atmosphere and adolescents' mental health aimed at avoiding NSSI behavior in adolescence.

The Relationship Between Illness Uncertainty and Social Support Among Cancer Patients: A Meta-analysis.

BACKGROUND: As a common psychological problem in cancer patients, illness uncertainty has attracted wide attention from scholars. Some studies have pointed out that the level of social support may affect illness uncertainty in patients with cancer, but the results of these studies remain controversial. OBJECTIVE: The aim of this study was to evaluate the correlation between illness uncertainty and social support in patients with cancer using meta-analysis. METHODS: PubMed, Web of Science, EMBASE, EBSCO, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and VIP Citation Database were searched for articles published up to 2022. The screening of the literature, data extraction, and quality assessment of the included studies were performed independently by 2 researchers. Stata 17.0 software was used to analyze the overall and moderation effects. RESULTS: Notably, 41 studies involving 5403 patients were included. The results showed that the illness uncertainty of adults with cancer was moderately negatively correlated with social support (r = -0.33). Country, publication year, cancer type, and instrument used to measure social support moderated the association between illness uncertainty and social support. CONCLUSION: Improving the level of social support can reduce illness uncertainty experienced by adults with cancer to a certain extent. IMPLICATIONS FOR PRACTICE: This review provides a clear direction for implementing precise interventions to reduce illness uncertainty among adults with cancer. Furthermore, patients with cancer with high morbidity and mortality rates deserve greater attention from healthcare personnel and family caregivers.

The relationship between childhood trauma and internet addiction in adolescents: A meta-analysis.

Objective: Many studies have explored the relationship between childhood trauma and internet addiction from different theoretical perspectives; however, the results have been inconsistent. The purpose of this meta-analysis was to examine the relationship between childhood trauma and internet addiction. Methods: The PubMed, Web of Science, Embase, CNKI, Wanfang and VIP electronic databases were searched to identify studies examining the correlation between childhood trauma and adolescent internet addiction. The databases were searched from inception to December 31, 2022. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias of the included studies. Then, Stata 17.0 software was used to perform meta-analysis. Results: This study was registered on PROSPERO (CRD42023388699). A total of 19 studies involving 21,398 adolescents were included in this meta-analysis. The random effects model was used for pooled analysis, and the results revealed a strong positive association between childhood trauma and internet addiction (r = 0.395, 95% CI [0.345, 0.442]). The relationship between childhood trauma and internet addiction was moderated by sample size, survey area, and internet addiction measurement tools. There were significant differences between the associations based on the various child trauma measurement tools and study quality scores. However, interstudy heterogeneity was not significantly affected by study year, sample source, or participant age. Conclusion: Internet addiction is positively correlated with childhood trauma. Therefore, it is extremely important for parents to provide a good growth environment during childhood to enhance the physical and mental development of adolescents. A warm family atmosphere helps individuals develop a healthy personality, thereby reducing or preventing the occurrence of internet addiction. Due to the limited number and low quality of the included studies, the above conclusions need to be verified by additional high-quality studies.

Correlates of death anxiety for patients with cancer: A systematic review and meta-analysis.

OBJECTIVE: A systematic review and meta-analysis was performed to identify the factors related to cancer death anxiety based on available evidence. DESIGN: This systematic review and meta-analysis followed the PRISMA 2020 guidelines. METHODS: Seven databases were searched to identify studies on the relationships of cancer death anxiety with demographic characteristics, disease factors and psychosocial factors from inception to May 2023. The Agency for Medical Research and Quality (AHRQ) scale was used to evaluate the quality of the included studies. After two researchers independently completed the literature search, data extraction and quality evaluation, meta-analysis was conducted by using RevMan5.3 and Stata 17.0 software. RESULTS: In total, 52 studies were included in this review. The results revealed that there were positive correlations of death anxiety with female sex, the symptom burden, anxiety levels, depression levels, fear of recurrence, attachment avoidance, psychological distress, resignation and confrontation coping. Death anxiety was negatively correlated with age, education level, ability to perform daily activities, self-esteem, spiritual well-being, sense of meaning in life, resilience, quality of life, social support and religious beliefs. CONCLUSIONS: Our results can inform the design of interventions to address death anxiety and improve the overall quality of life of cancer patients. Healthcare professionals should promptly identify and focus on death anxiety in high-risk populations of cancer patients. RELEVANCE TO CLINICAL PRACTICE: Cancer patients commonly experience death anxiety, and this anxiety has a nonnegligible impact on patients' mental health and overall quality of life. This study can inform the development of interventions by clinical healthcare professionals. NO PATIENT OR PUBLIC CONTRIBUTION: This was a meta-analysis based on data from previous studies.

Estrogen plays an important role by influencing the NLRP3 inflammasome.

The nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome is an important part of the natural immune system that plays an important role in many diseases. Estrogen is a sex hormone that plays an important role in controlling reproduction and regulates many physiological and pathological processes. Recent studies have indicated that estrogen is associated with disease progression. Estrogen can ameliorate some diseases (e. g, sepsis, mood disturbances, cerebral ischemia, some hepatopathy, Parkinson's disease, amyotrophic lateral sclerosis, inflammatory bowel disease, spinal cord injury, multiple sclerosis, myocardial ischemia/reperfusion injury, osteoarthritis, and renal fibrosis) by inhibiting the NLRP3 inflammasome. Estrogen can also promote the development of diseases (e.g., ovarian endometriosis, dry eye disease, and systemic lupus erythematosus) by upregulating the NLRP3 inflammasome. In addition, estrogen has a dual effect on the development of cancers and asthma. However, the mechanism of these effects is not summarized. This article reviewed the progress in understanding the effects of estrogen on the NLRP3 inflammasome and its mechanisms in recent years to provide a theoretical basis for an in-depth study.

The relationship between stigma and psychological distress among people with diabetes: a meta-analysis.

BACKGROUND & AIMS: Diabetes may perceive or experience varying degrees of stigma and psychological distress. The association between diabetes-related stigma and psychological distress has been examined in many studies, but no research has used a quantitative synthesis method to investigate the severity of this association and the moderators of the relationship. Thus, we conducted a meta-analysis to quantitatively integrate previous findings to identify the magnitude of the association between stigma and psychological distress among people with diabetes. REVIEW METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, we systematically searched four English academic databases (PubMed, Embase, Web of Science, and PsycINFO) and three Chinese databases (China National Knowledge Infrastructure [CNKI], WANFANG Data, China Science and Technology Journal Database [VIP]). The databases were searched from the inception of each database to the end of March 2023. The pooled correlation coefficient of the association between stigma and psychological distress among people with diabetes was calculated by a random effects model using Stata software (version 17.0), and several moderators that impacted this relationship were identified. RESULTS: Eligible studies (N = 19) with a total of 12,777 participants were analysed. The pooled correlation was high between diabetes-related stigma and psychological distress (r = 0.50, 95% CI: [0.43-0.57]). Moreover, the association was moderated by the diabetes stigma measurement tools and diabetes distress measurement tools used. However, the relationship was not moderated by type of diabetes, age, gender, geographical location, or type of stigma. CONCLUSIONS: The results of the meta-analysis showed that stigma is strongly related to psychological distress among people with diabetes. Longitudinal or experimental research should be expanded in the future to further identify the causal pathways in the relationship between diabetes stigma and diabetes distress.

The effect of parenting styles on Chinese undergraduate nursing students' academic procrastination: the mediating role of causal attribution and self-efficacy.

Background: Academic procrastination is common among college students, but there is a lack of research on the influencing mechanism of academic procrastination among nursing students. The purpose of this study was to explore the influence of parental rearing patterns on academic procrastination of nursing students, and the mediating role of causal attribution and self-efficacy. Methods: Using Parental Bonding Instrument, Aitken Procrastination Inventory, Multidimensional Multi-Attribution Causality Scale and General Self-Efficiency Scale, the data of 683 nursing undergraduates from two universities in China were collected. Moreover, path analysis for structural equation modeling via AMOS 26.0 to evaluate mediation path model. Results: Positive parenting style was negatively associated with academic procrastination (r = -0.350) and negative parenting style was positively associated with academic procrastination (r = 0.402). Positive parenting style directly or indirectly predicted academic procrastination through the mediating effect of internal attributional style (ß = -0.10, 95% CI: -0.18 to -0.04) and self-efficacy (ß = -0.07, 95% CI: -0.11 to -0.03), and this mediating effect accounted for 41.46% of the total effect. Positive parenting style directly or indirectly predicted academic delay through the mediating effect of external attributional style (ß = 0.12, 95% CI: 0.07 to 0.17) and self-efficacy (ß = 0.05, 95% CI: 0.03 to 0.08), and this mediating effect accounted for 42.5% of the total effect. In addition, causal attribution and self-efficacy of nursing students play a chain intermediary role between parenting style and academic procrastination. Conclusion: Parents should give students more care and autonomy and reduce control. In addition, educators should give students attribution training, which is helpful to improve students' self-efficacy and reduce academic procrastination.

Perceived parenting style and Chinese nursing undergraduates' learning motivation: The chain mediating roles of self-efficacy and positive coping style.

AIM: The aim of this study was to examine the chain mediating effects of self-efficacy and positive coping style on the relationship between parenting style and learning motivation in Chinese nursing students. BACKGROUND: Despite the abundance of literature that focuses on learning motivation, there is a lack of research that accurately and thoroughly examines the factors that influence learning motivation among nursing students. DESIGN: This study involved a cross-sectional design. METHODS: In total, 677 Chinese undergraduate nursing students completed the parental bonding instrument, the general self-efficacy scale, the simplified coping style questionnaire, and the learning motivation scale. A structural equation model was performed with AMOS 26.0 to explore the influence paths of variables and the mediating effects of self-efficacy and coping style. RESULTS: Parental care positively predicted intrinsic learning motivation directly or indirectly through the mediating effects of self-efficacy (B = 0.17, 95% CI: 0.12-0.23) and positive coping style (B = 0.03, 95% CI: 0.01-0.06), and this mediating effect contributed 54.06% of the total effect. Parental encouraging autonomy positively predicted intrinsic learning motivation indirectly through the mediating effects of self-efficacy (B = 0.17, 95% CI: 0.12-0.24) and positive coping style (B = 0.03, 95% CI: 0.01-0.06), and this mediating effect contributed 71.42% of the total effect. Parental control negatively influenced intrinsic learning motivation directly or indirectly through the mediating effects of self-efficacy (B = -0.10, 95% CI: -0.15 to -0.04) and positive coping style (B = -0.02, 95% CI: -0.05 to -0.01), and this mediating effect contributed 42.85% of the total effect. CONCLUSION: Parents should provide more care and autonomy to nursing students and reduce control over them. Nurse educators should consider targeted improvement strategies to improve the level of self-efficacy and positive coping style of nursing undergraduates to enable them to maintain a more intrinsic learning motivation.

The role of taurine in male reproduction: Physiology, pathology and toxicology.

Taurine, a sulfur-containing amino acid, has a wide range of biological effects, such as bile salt formation, osmotic regulation, oxidative stress inhibition, immunomodulation and neuromodulation. Taurine has been proved to be synthesized and abundant in male reproductive organs. Recently, accumulating data showed that taurine has a potential protective effect on reproductive function of male animals. In physiology, taurine can promote the endocrine function of the hypothalamus-pituitary-testis (HPT) axis, testicular tissue development, spermatogenesis and maturation, delay the aging of testicular structure and function, maintain the homeostasis of the testicular environment, and enhance sexual ability. In pathology, taurine supplement may be beneficial to alleviate pathological damage of male reproductive system, including oxidative damage of sperm preservation in vitro, testicular reperfusion injury and diabetes -induced reproductive complications. In addition, taurine acts as a protective agent against toxic damage to the male reproductive system by exogenous substances (e.g., therapeutic drugs, environmental pollutants, radiation). Related mechanisms include reduced oxidative stress, increased antioxidant capacity, inhibited inflammation and apoptosis, restored the secretory activity of the HPT axis, reduced chromosomal variation, enhanced sperm mitochondrial energy metabolism, cell membrane stabilization effect, etc. Therefore, this article reviewed the protective effect of taurine on male reproductive function and its detailed mechanism, in order to provide reference for further research and clinical application.

The effect of prosocial behaviours on Chinese undergraduate nursing students' subjective well-being: The mediating role of psychological resilience and coping styles.

This study aimed to explore the effect of prosocial behaviours on Chinese undergraduate nursing students' subjective well-being (SWB) and examine the roles of psychological resilience and coping styles. The sample for this study included 683 nursing students from two undergraduate universities in Henan Province, China. SWB, prosocial behaviours, psychological resilience, and coping styles were assessed by the Index of Well-Being, the Prosocial Behavioural Tendency Scale, the Connor-Davidson Resilience Scale, and the Simplified Coping Style Questionnaire, respectively. We adopted Pearson's correlation analysis and the PROCESS Macro Model 81 in regression analysis to explore the relationships among prosocial behaviours, psychological resilience, coping styles, and SWB. Prosocial behaviours of undergraduate nursing students had a positive predictive effect on SWB; psychological resilience and coping styles both were the mediating variable between prosocial behaviours and undergraduate nursing students' SWB; psychological resilience and coping styles played a chain mediating role between the prosocial behaviours and SWB of undergraduate nursing students. The results indicated that prosocial behaviours not only directly affected the SWB of undergraduate nursing students but also affected the SWB of undergraduate nursing students via psychological resilience and coping styles. These results offer certain theoretical support and guidance for the research and improvement of undergraduate nursing students' SWB and emphasize the importance of interventions to increase prosocial behaviours, improve psychological resilience, promote positive coping styles, and address negative coping styles.

Effects of Lycopene Attenuating Injuries in Ischemia and Reperfusion.

Tissue and organ ischemia can lead to cell trauma, tissue necrosis, irreversible damage, and death. While intended to reverse ischemia, reperfusion can further aggravate an ischemic injury (ischemia-reperfusion injury, I/R injury) through a range of pathologic processes. An I/R injury to one organ can also harm other organs, leading to systemic multiorgan failure. A type of carotenoid, lycopene, has been shown to treat and prevent many diseases (e.g., rheumatoid arthritis, cancer, diabetes, osteoporosis, male infertility, neurodegenerative diseases, and cardiovascular disease), making it a hot research topic in health care. Some recent researches have suggested that lycopene can evidently ameliorate ischemic and I/R injuries to many organs, but few clinical studies are available. Therefore, it is essential to review the effects of lycopene on ischemic and I/R injuries to different organs, which may help further research into its potential clinical applications.
