RESUMEN

OBJECTIVES: Childhood adversity and lifestyle have been associated with frailty in later life, but not much is known about factors that may explain these associations. Therefore, this study aims to investigate the association of childhood adversity with frailty, and the mediating role of unhealthy lifestyle in the association. METHODS: This lifespan analysis included 152,914 adults aged 40-69 years old from the UK Biobank. We measured childhood adversity with five items: physical neglect, emotional neglect, sexual abuse, physical abuse, and emotional abuse through online mental health survey. Frailty was measured by the frailty index; an unhealthy lifestyle score (range: 0-5) was calculated based on unhealthy body mass index, smoking, alcohol consumption, physical inactivity, and unhealthy diet at the baseline survey. Multiple logistic regression and mediation analysis were performed. RESULTS: A total of 10,078 participants (6.6%) were defined as having frailty. Participants with any childhood adversity had higher odds of frailty. For example, in the fully adjusted model, with a one-point increase in cumulative score of childhood adversity, the odds of frailty increased by 38% (odds ratio: 1.38; 95% Confidence Interval: 1.36, 1.40). Unhealthy lifestyle partially mediated the associations of childhood adversity with frailty (mediation proportion: 4.4%-7.0%). The mediation proportions were largest for physical (8.2%) and sexual (8.1%) abuse. CONCLUSIONS: Childhood adversity was positively associated with frailty, and unhealthy lifestyle partially mediated the association. This newly identified pathway highlights the potential of lifestyle intervention strategies among those who experienced childhood adversity (in particular, physical, and sexual abuse) to promote healthy aging.

RESUMEN

BACKGROUND: It has been documented that social media addiction (SMA) has a detrimental effect on college students' academic engagement. However, the mechanisms underlying this association are not well understood. This study aimed to determine the serial mediation effects of sleep quality and fatigue on the relationship between SMA and academic engagement among college students. METHODS: A cross-sectional survey was conducted with 2661 college students (43.3% males, mean age = 19.97 years). The participants completed the Bergen Social Media Addiction Scale, the Utrecht Student Work Engagement Scale for Students, the Pittsburgh Sleep Quality Index, and the Fatigue Assessment Scale. The serial mediation effects were examined using Model 6 in the Hayes' PROCESS macro for SPSS. RESULTS: The results showed that SMA among college students had a direct negative relationship with their academic engagement (Effect = - 0.051, 95% CI: -0.087 to - 0.015). In addition, sleep quality and fatigue mediated the relationship between SMA and academic engagement both independent and serially, with the independent mediation effect of sleep quality being - 0.031 (95% CI: -0.048 to - 0.016), the independent mediation effect of fatigue being - 0.109 (95% CI: -0.133 to - 0.088), and the serial mediation effect of sleep quality and fatigue being - 0.080 (95% CI: -0.095 to - 0.066). The total indirect effect of the three mediation paths was 80.9%. CONCLUSIONS: Decreased academic engagement caused by SMA can be aggravated by poor sleep quality and fatigue. Strengthening supervision and intervention in social media use among college students, supplemented by attention to psychosomatic health, including sleep quality and fatigue could promote their engagement in academic work.

RESUMEN

OBJECTIVES: This study investigates the relationship between emotional symptoms and dental caries in adolescents and the role of dietary patterns as mediating variables. METHODS: This cross-sectional study used a multistage stratified random sample of schools, in Jiangsu, with a sample of 17,997 adolescents aged 11-19. Measures included emotional symptoms, dental caries, toothbrushing frequency, and dietary patterns. Logistic and Poisson regression models were conducted to test mediation hypotheses. RESULTS: The decayed, missing, and filled teeth index (DMFT) was related to depressive symptoms following adjustment for other variables (incidence rate ratios [IRR] = 1.09; p < 0.05), but not to anxiety symptoms level (IRR = 1.02; p > 0.05). The link between depressive symptoms and DMFT had a partial mediation impact on toothbrushing frequency (a, b, c' all p < 0.05). Sugary foods, but not fried foods, partially mediated the link between depressive symptoms and caries when toothbrushing frequency was adjusted. CONCLUSION: There are direct and indirect associations between emotional symptoms and caries; the latter may be due to changes in oral health behaviours that increase the risk of caries.

RESUMEN

Ten jatrophane diterpenoids were isolated from the whole plant Euphorbia peplus Linn. including seven new ones, named euphjatrophanes A-G (labeled compounds 1, 2, 4-8). Their structures were elucidated with a combination of spectroscopic and single-crystal X-ray crystallography, enabling the identification of compounds 3, 9, and 10 as the previously published euphpepluones G, K, and L, respectively. All compounds were evaluated for their bioactivity with flow cytometry in assays of autophagic flux in HM Cherry-GFP-LC3 (human microglia cells stably expressing the tandem monomeric mCherry-GFP-tagged LC3) cells. Euphpepluone K (9) significantly activated autophagic flux, an effect that was verified with confocal analysis. Moreover, cellular assays showed that euphpepluone K (9) induced autophagy and inhibited Tau pathology.

RESUMEN

We have previously demonstrated that Arabidopsis (Arabidopsis thaliana) phloem protein PP2-A1 is an integral component of resistance to the green peach aphid (Myzus persicae). Here, we report that M. persicae overcomes the resistance of PP2-A1 by using the salivary protein Mp1 as an energetic effector and an interactor of AtPP2-A1. Using the RNA interference technique, we demonstrated that Mp1 plays an essential role in the phloem-feeding activity of M. persicae. When the Mp1 gene was silenced, aphids incurred serious impairments not only in phloem-feeding activity, but also in survival and fertility. In essence, phloem-feeding activity was attributed to the molecular interaction between Mp1 and AtPP2-A1. The Mp1 and AtPP2-A1 interactions were localized to plant cell membranes by co-immunoprecipitation and bimolecular fluorescence complementation experiments. Furthermore, the interaction was found to be required for aphid feeding on Arabidopsis phloem. Overall, our results suggest that Mp1 is an important effector of M. persicae and interacts with AtPP2-A1 to facilitate infestation in the plant tissue by this insect.

RESUMEN

BACKGROUND: Vitamin D deficiency has been associated with type 2 diabetes (T2D) and metabolic syndrome (MS) and its components. However, it is unclear whether a low concentration of vitamin D is the cause or consequence of these health conditions. Thus, this study aimed to evaluate the association of vitamin D concentrations and its genetic risk scores (GRSs) with MS and its component diseases, such as T2D, in middle-aged and elderly participants from rural eastern China. METHODS: A subset of 2393 middle-aged and elderly individuals were selected from 70,458 participants of the Nantong Chronic Diseases Study of 2017-2018 in China. We used two 25-hydroxyvitamin D (25[OH]D) synthesis single-nucleotide polymorphisms (SNPs) (DHCR7-rs12785878 and CYP2R1-rs10741657) and two 25(OH) D metabolism SNPs (GC-rs2282679 and CYP24A1-rs6013897) for creating GRSs, which were used as instrumental variables to assess the effect of genetically lowered 25(OH) D concentrations on MS and T2D based on the Wald ratio. F statistics were used to validate that the four SNPs genetically determined 25(OH) D concentrations. RESULTS: Compared to vitamin D sufficient individuals, individuals with vitamin D insufficiency had an odds ratio (OR [95% confidence interval {CI}]) of MS of 1.30 (1.06-1.61) and of T2D of 1.32 (1.08-1.64), individuals with vitamin D deficiency had an ORs (95% CI) of MS of 1.50 (1.24-1.79) and of T2D of 1.47 (1.12-1.80), and those with vitamin D severe deficiency had an ORs (95% CI) of MS of 1.52 (1.29-1.85) and of T2D of 1.54 (1.27-1.85). Mendelian randomization analysis showed a 25-nmol/L decrease in genetically instrumented serum 25(OH) D concentrations using the two synthesis SNPs (DHCR7 and CYP2R1 genes) associated with the risk of T2D and abnormal diastolic blood pressure (DBP) with ORs of 1.10 (95%CI: 1.02-1.45) for T2D and 1.14 (95%CI: 1.03-1.43) for DBP. CONCLUSIONS: This one sample Mendelian randomization analysis shows genetic evidence for a causal role of lower 25(OH) D concentrations in promoting of T2D and abnormal DBP in middle-aged and elderly participants from rural China.

RESUMEN

The first phytochemical investigation of the seeds of Euphorbia peplus led to the isolation and characterization of five new (1-5), named euphopepluanones A-E, and five known diterpenoids (6-10). Their structures were established by extensive spectroscopic analysis and X-ray crystallographic experiments. Euphopepluanones A-E (1-3) feature a very rare 5/11/5-tricyclic skeleton, and euphopepluanones D-E (4-5) represent the first report of lathyrane type diterpenoids found in E. peplus. The new compounds 1-5 were assessed for their activities to induce lysosomal biogenesis through LysoTracker Red staining, in which compounds 1 and 3 could significantly induce lysosomal biogenesis. In addition, compounds 1 and 3 could promote the nuclear translocation of TFEB, a master transcriptional factor of lysosomal genes, indicating that compounds 1 and 3 induced lysosomal biogenesis through activation of TFEB.

RESUMEN

A methodology based on light scattering and spectrophotometry was developed to evaluate the effect of organic surfactants on the size and yield of eutectic gallium/indium (EGaIn) nanodroplets formed in organic solvents by ultrasonication. The process was subsequently applied to systematically evaluate the role of headgroup chemistry as well as polar/apolar interactions of aliphatic surfactant systems on the efficiency of nanodroplet formation. Ethanol was found to be the most effective solvent medium in promoting the formation and stabilization of EGaIn nanodroplets. For the case of thiol-based surfactants in ethanol, the yield of nanodroplet formation increased with the number of carbon atoms in the aliphatic part. In the case of the most effective surfactant system-octadecanethiol-the nanodroplet yield increased by about 370% as compared to pristine ethanol. The rather low overall efficiency of the reaction process along with the incompatibility of surfactant-stabilized EGaIn nanodroplets in nonpolar organic solvents suggests that the stabilization mechanism differs from the established self-assembled monolayer formation process that has been widely observed in nanoparticle formation.

RESUMEN

Research investigating the influence of emotion regulation (ER) strategies on emotional eating and diet among Chinese adolescents is scarce. The aim of this study was to test associations between two ER strategies (suppression/cognitive reappraisal), emotional eating, and an energy-rich dietary pattern. A total of 4316 adolescents from 10 high schools were surveyed. Dietary patterns were derived using factor analysis. Bivariate correlations were analyzed to examine associations between ER strategies, emotional eating behavior and an energy-rich dietary pattern, by gender. The mediating effect of emotional eating in the relationship between ER and energy-rich food consumption by gender was estimated using structural equation modeling. A higher level of suppression, but no lack of cognitive reappraisal, was associated with emotional eating in boys and girls. A higher level of suppression and lack of cognitive reappraisal were associated with a greater intake of energy-rich foods in girls only. Emotional eating mediated the relationship between a higher level of suppression and a greater intake of energy-rich food in girls. This study revealed significant associations between two ER strategies and an energy-rich dietary pattern in girls, and provided evidence that higher levels of suppression may put girls at risk for emotional eating, potentially affecting the energy-rich dietary pattern.

RESUMEN

The prevalence of metabolic syndrome increases rapidly worldwide, and its association with physical activity (PA) varies with race and lifestyles. Little is known about the association in rural China. The Nantong Metabolic Syndrome Study recruited 13,505 female and 6997 male participants in 2007 and 2008. Socio-demographic characteristics, and physiological and behavioural data were collected. Logistic regression model was applied to estimate associations of metabolic syndrome and its components with different PAs. The overall metabolic syndrome prevalence was 21.6% in current study. Increasing total PA or moderate-to-vigorous-intensity occupational PA was associated with decreasing 5%-60% risk of having metabolic syndrome and abnormal metabolic syndrome components in both genders. An association between leisure-time PA and blood pressure was found in men, but no associations between leisure-time PA and metabolic syndrome components were found in women. Commuting PA, such as walking and taking bus, by bicycle and walking only, was associated with decrease of 20%-45% risk of several abnormal metabolic syndrome components in women. This study provides information for future investigation into the nature of these associations so that recommendations can be developed to reduce the prevalence of metabolic syndrome and its components among rural population in China.

RESUMEN

The purpose of this study is to test the relation of cortisol reactivity, delay discounting and percent body fat (PBF) in adolescents aged 12-13 years (N=87), and evaluate the delay discounting as potential components in models of adolescent obesity. Anthropometry and body composition measurements were assessed in adolescents. The cortisol reactivity to Trier Social Stress Test for Children (TSST-C) and delay discounting were measured. The result showed increased cortisol reactivity and greater delay discounting were associated with higher PBF in girls. Structural equation modeling supported greater delay discounting as a mediator of relations between increased cortisol reactivity and PBF in adolescent girls. The proposed mediation model indicated that cortisol reactivity is linked to PBF through delay discounting, thereby supporting a significant indirect relationship. The direct relationship between increased cortisol reactivity and higher PBF was significant in a model that did not include delay discounting, and was still significant in the mediation model that included delay discounting. This study provides the first evidence that greater delay discounting may partially account for the relationship of hyperactivity of the HPA-axis and higher PBF in girls.

RESUMEN

BACKGROUND: Social anxiety has been shown to affect college students' academic performance. However, the role of social media addiction and academic engagement in this association is unclear. METHODS: A total 2661 college students completed a self-report questionnaire including Liebowitz Social Anxiety Scale, the Bergen Social Media Addiction Scale, the Utrecht Student Work Engagement Scale for Students, and the grade point average. Hayes' PROCESS macro for SPSS was employed to test the serial mediation effect. RESULTS: Results indicated that social anxiety was negatively related to academic performance, only academic engagement played a single mediating role in the relationship between social anxiety and academic performance, meanwhile social media addiction and academic engagement acted as serial mediators between social anxiety on academic performance. CONCLUSIONS: Social media addiction and academic engagement can explain the potential mechanisms of the association between social anxiety and academic performance, which have implications for devising intervention strategies to enhance the mental health and academic outcomes of college students.

RESUMEN

BACKGROUND: Social media addiction (SMA) is an increasing problem, especially among young adults. Little is known about university students' SMA and family functioning. This study aimed to explore the mediating effect of depressive symptoms and the moderating effect of peer support in the relationship between family functioning and SMA among young adults. METHODS: A sample of 1862 Chinese university students completed an online survey including the Bergen Social Media Addiction Scale (BSMAS), Family APGAR, the Patient Health Questionnaire (PHQ-9), peer support, and demographic characteristics. Hierarchical regression and moderated mediation analysis were used to test the effects and pathways among them. RESULTS: Of the 1840 participants, 30.11% experienced SMA, 38.80% had family dysfunction and 15.98% had depressive symptoms. Hierarchical multiple regression showed better family functioning significantly predicted less SMA (ß = -0.26, p < 0.001) and lower depressive symptoms (ß = -0.58, p < 0.001), after adjusting for covariates. Mediation analysis verified that depressive symptoms mediated the effect of family functioning on SMA (indirect effect = -0.22, 95%CI[-0.28, -0.17]). Furthermore, the interaction of family functioning and peer support was negatively related to depressive symptoms (ß= -0.03, 95% CI[-0.05, -0.01]) and the interaction of depressive symptoms and peer support was positively related to SMA (ß = 0.01, 95%CI[0.004, 0.02]). Additional analysis further confirmed that peer support decreased depressive symptoms among young adults from dysfunctional families, and increased SMA behaviors in individuals with depressive symptoms. CONCLUSION: Better family functioning and lower depressive symptoms may contribute to less social media addiction among Chinese university students. Peer support could moderate the mediating role of depressive symptoms on social media addiction in individuals with family dysfunction.

RESUMEN

The aim of this study was to explore possible effects of emotional symptoms (depressive symptoms and anxiety symptoms) and life stress on eating behaviors (restrained, emotional and external eating behaviors) among junior and high school students in China. A total of 5473 students in Xuzhou, Jiangsu Province were sampled to participate in this survey based on a clustering sampling approach. The survey collected sociodemographic data, emotional symptoms, life stress and eating behaviors of adolescents. Spearman correlation coefficients were measured and tested to examine the relationship between eating behaviors and emotional symptoms as well as life stress. In addition, we analyzed the data using Chi-square tests and multivariate logistic regression models. The results showed positive correlation between emotional symptoms, life stress, and eating behaviors. Furthermore, depressive symptoms, anxiety symptoms and life stress were significantly associated with unhealthy eating behaviors, after adjusting for gender, age, BMI, parental education level and self-assessed family economic status. This study suggests that a comprehensive intervention focusing on emotion and stress management would be helpful for the prevention of unhealthy eating behaviors among Chinese adolescents.

RESUMEN

Background: Signal transducers and activators of transcription (STAT) proteins, well-known cytoplasmic transcription factors, were found to be abnormally expressed in various cancers and play essential parts in the initiation, progression and therapy resistance of cancer. Nevertheless, the functions of different STATs in pancreatic cancer (PC) and their relationship to the prognosis and immune infiltration as well as drug efficacy in PC patients have not been systematically elucidated. Methods: Expression, prognosis, genetic alterations and pathway enrichment analyses of the STAT family were investigated via Oncomine, GEPIA, Kaplan Meier-plotter, cBioPortal, Metascape and GSEA. Analysis of tumor immune microenvironment was conducted by ESTIMATE and TIMER. "pRRophetic" packages were used for analysis of chemotherapeutic response. Finally, the diagnostic and prognostic value of key STATs were further validated through public datasets and immunohistochemistry. Results: In this study, only STAT1 mRNA level was significantly increased in tumor tissues and highly expressed in PC cell lines via multiple datasets. PC patients with higher STAT1/4/6 expression had a worse overall survival (OS) and progression-free survival (PFS), while higher STAT5B expression was correlated with better prognosis in the TCGA cohort. The STATs-associated genes were enriched in pathways about the remodeling of tumor immune microenvironment. The STATs levels were significantly correlated with immune infiltration, except STAT6. The STAT1 was identified as a potential biomarker and its diagnostic and prognostic value were further validated at mRNA and protein levels. GSEA showed that STAT1 may be involved in the progression and immune regulations of PC. Moreover, STAT1 expression was significantly related to the level of immune checkpoint, and predicted immunotherapy and chemotherapy responses. Conclusion: STAT family members were comprehensively analyzed and STAT1 was identified as an effective biomarker for predicting the survival and therapeutic response, which could be beneficial to develop better treatment strategies.

RESUMEN

A new ent-abietane diterpenoid, named Euphejolkinolide A (1), was isolated from the whole plant of Euphorbia peplus L. Its structure, including absolute configurations, was determined by spectroscopic analyses and was corroborated by single-crystal X-ray diffraction analysis. This new compound was assessed for its activity to induce lysosome biogenesis through Lyso-Tracker Red staining, in which compound 1 could significantly induce lysosome biogenesis. In addition, quantitative real-time PCR (qRT-PCR) analysis demonstrated a direct correlation between the observed lysosome biogenesis and the transcriptional activation of the lysosomal genes after treatment with the compound 1. Moreover, compound 1 promoted autophagic flux by upregulating LC3-II and downregulating SQSTM1 in both human microglia cells and U251 cells, which is required for cellular homeostasis. Further results suggested 1 induced lysosome biogenesis and autophagy which was mediated by TFEB (transcription factor EB). The structure activity relationships (SAR) analysis suggested that the carbony1 at C-7 in 1 might be a key active group. Overall, the current data suggested that 1 could be a potential compound for lysosome disorder therapy by induction of autophagy.

RESUMEN

Background: Childhood adversity and lifestyle have been associated with frailty in later life, but not much is known about factors that may explain these associations. An unhealthy lifestyle may play an important role in the pathway from childhood adversity to frailty. Therefore, this study aims to investigate the association of childhood adversity with frailty, and the mediating role of unhealthy lifestyle in the association. Methods: This lifespan analysis included 152914 adults aged 40-69 years old from the UK Biobank. We measured childhood adversity with five items: physical neglect, emotional neglect, sexual abuse, physical abuse, and emotional abuse through online mental health survey. Frailty was measured by the frailty index; an unhealthy lifestyle score (range: 0-5) was calculated based on unhealthy body mass index, smoking, drinking, physical inactivity, and unhealthy diet at the baseline survey. Multiple logistic regression and mediation analysis were performed. Results: A total of 10078 participants (6.6%) were defined as having frailty. Participants with any childhood adversity had higher odds of frailty. For example, in the fully adjusted model, with a one-point increase in cumulative score of childhood adversity, the odds of frailty increased by 41% (Odds Ratio: 1.41; 95% Confidence Interval: 1.39, 1.44). Unhealthy lifestyle partially mediated the associations of childhood adversity with frailty (mediation proportion: 4.4%-7.0%). The mediation proportions were largest for physical (8.2%) and sexual (8.1%) abuse. Conclusions: Among this large sample, childhood adversity was positively associated with frailty, and unhealthy lifestyle partially mediated the association. This newly identified pathway highlights the potential of lifestyle intervention strategies among those who experienced childhood adversity (in particular, physical and sexual abuse) to promote healthy aging.

RESUMEN

Foodborne diseases (FBDs) are a major public health concern, especially in Sub-Saharan African (SSA) countries, such as Ghana, where poor food handling practices (FHPs) are prevalent. To estimate the pooled proportion of good FHPs and the associated factors among Ghanaian food handlers, this systematic review and meta-analysis was conducted to aid scholars, practitioners and policymakers in devising FBD-preventable interventions. The scientific databases PubMed, Google Scholar, Science Direct, African Journals Online, ProQuest, and Directory of Open Access Journals were systematically searched until April 19, 2023, for relevant literature. Observational studies meeting the inclusion criteria of reported good FHPs among food handlers were included. Three authors independently searched the database, assessed the risks of bias and extracted the data from the shortlisted articles. A random-effects model with the DerSimonian and Laird model was used to estimate the pooled effect size of FHPs and the pooled odds ratio (POR) of FHP-associated factors. Out of the 2019 records collated, 33 with a total sample size of 6095 food handlers met the inclusion criteria for meta-analysis. The pooled proportion of good FHPs among Ghanaian food handlers was 55.8% [95% Cl (48.7, 62.8%); I2 = 97.4%; p < 0.001]. Lack of food safety training [POR = 0.10; 95% CI (0.03, 0.35); p = 0.001] and inadequate knowledge of food hygiene [POR = 0.36; 95% CI (0.01, 10.19); p < 0.001] were identified as the critical good FHP-associated factors. The study showed that the proportion of good FHPs among Ghanaian food handlers was 55.8%.

RESUMEN

OBJECTIVE: To survey patients with chronic hepatitis B (CHB) to determine their perceptions of CHB-related quality of life (QOF) and to determine the factors influencing this measure. METHODS: A total of 268 patients with CHB (disease group) and 205 healthy individuals (control group) completed the World Health Organization (WHO)QOL-BREF life assessment survey and a self-designed questionnaire of health and QOL. The groups' responses were comparatively analyzed by the cluster sampling method and the independent samples t-test. The strength of influence of each factor on the patients' perceptions of QOL was determined by multiple stepwise regression and one-way ANOVA. RESULTS: The disease group had significantly lower scores than the control group for overall QOL (62.88 ± 8.22 vs. 67.31 ± 5.82), the physiological area (PHYS: 64.71 ± 15.05 vs. 73.21 ± 11.26), the psychological area (PSYCH: 64.35 ± 14.71 vs. 68.94 ± 10.13), the social relations area (SOCIL: 67.20 ± 12.98 vs. 69.83 ± 8.65), the environmental area (ENVIR: 59.58 ± 13.23 vs. 63.97 ± 10.24), the QOL self-assessment (60.75 ± 21.54 vs. 66.90 ± 17.57) and the health self-assessment (58.13 ± 19.15 vs. 76.26+/-14.27) (all, P less than 0.05). Multiple stepwise regression analysis identified the following parameters as risk factors of PHYS: depression (P less than 0.001), perception of being seriously ill (P less than 0.001), self-payment for treatment (P = 0.003), CHB significant impact on income (P = 0.002), poor appetite (P = 0.002), langur (P less than 0.001), and fear of infecting others (P = 0.022). Confidence of treatment was a protective factor of PHYS (P = 0.001). The risk factors of PSYCH were depression (P less than 0.001) and recurrence (P less than 0.001), and the protective factors were confidence of treatment (P = 0.003) and male sex (P = 0.014). The risk factors of SOCIL were depression (P less than 0.001, dissatisfaction with the attitude of the people around (P = 0.001), recurrence (P = 0.008), and advanced age (P = 0.009), and the protective factors were social support (P less than 0.001) and confidence of treatment (P = 0.015); however, the scores were significantly different for different occupations (P = 0.008). The risk factors of ENVIR were depression (P less than 0.001), dissatisfaction with the attitude of the people around (P less than 0.001), living in rural area (P = 0.007), and recurrence (P = 0.016). CONCLUSION: Patients should be monitored for depressive symptoms during the course of clinical medical care for CHB so that psychological care may be initiated in a timely manner. It is important to strengthen communication between healthcare professionals and patients in order to improve the patient's perception of social support and quality of life.

RESUMEN

The aim of the study was to explore the effect of intensive psychological nursing intervention on HAMD and SF-36 scores in patients with severe liver cancer in intensive care unit (ICU). 134 critically ill patients with liver cancer in ICU who underwent resection of primary liver cancer from July 2019 to November 2021 were selected. The patients were randomly divided into control group and study group. The patients in the control group received routine nursing. The patients in the study group received intensive psychological nursing intervention on the basis of routine nursing. Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and the MOS 36-item short-form health survey (SF-36) scores before and after nursing were compared between the two groups. The satisfaction of the two groups of patients with nursing was counted. The HAMA, HAMD, and SF-36 scores of patients receiving intensive psychological nursing intervention were significantly better than those receiving routine nursing. The nursing satisfaction of patients receiving intensive psychological nursing intervention was significantly higher than that of patients receiving routine nursing. Intensive psychological nursing intervention for patients with severe liver cancer in ICU can significantly reduce HAMD, improve SF-36 score, and patient nursing satisfaction. It is worthy of wide clinical promotion.
