OBJECTIVE: Guided by the hedonic surplus/mood-as-resource hypotheses, we sought to identify message components that prevent health information avoidance by inducing hedonic psychological states.
METHODS: Two experimental studies.
METHODS: Participants, age 45-75, recruited from the online survey platform, Prolific (Study 1 N = 288, Study 2 N = 505), completed a survey of their colorectal cancer (CRC) information avoidance tendency and demographics. They were reinvited to participate in a study where they were randomized to view one of four types of images: humorous comics, cute animals, coping messages or streetscapes images (control condition). To assess CRC information avoidance behaviour after viewing the stimuli, participants choose whether to be directed to a website to complete a CRC risk calculator (Study 1), or whether to view a CRC information video or a video about foot care (Study 2). Using logistic regression, we regressed each outcome variable on interactions between self-reported CRC information avoidance tendency and experimental condition. We then used the PROCESS macro to test if mood mediated these interaction effects.
RESULTS: In Study 1, to the degree participants reported CRC information avoidance tendency, viewing humorous comics compared to control images increased their odds of choosing to view the risk calculator (OR = 5.26, p = .02). The same was true in Study 2 for choosing to watch the video about CRC vs. foot care (OR = 2.42, p = .04). Effects were not mediated through mood and there were no effects for the cute animals or coping messages.
CONCLUSIONS: Using humour at the outset of a health message may increase reach to people who otherwise avoid CRC or other health messaging.

Candida auris is an emerging multi-drug resistant yeast that can cause life-threatening infections. A recent report clarified the ability of C. auris to form a biofilm with enhanced drug resistance properties in the host skin\'s deep layers. The formed biofilm may initiate further bloodstream spread and immune escape. Therefore, we propose that secreted chemicals from the biofilm may facilitate fungal pathogenesis. In response to this interaction, the host skin may develop potential defensive mechanisms. Comparative transcriptomics was performed on the host dermal cells in response to indirect interaction with C. auris biofilm through Transwell inserts compared to planktonic cells. Furthermore, the effect of antifungals including caspofungin and fluconazole was studied. The obtained data showed that the dermal cells exhibited different transcriptional responses. Kyoto Encyclopedia of Genes and Genomes and Reactome analyses identified potential defensive responses employed by the dermal cells and potential toxicity induced by C. auris. Additionally, our data indicated that the dominating toxic effect was mediated by ferroptosis; which was validated by qRT-PCR, cytotoxicity assay, and flow cytometry. On the other hand, the viability of C. auris biofilm was enhanced and accompanied by upregulation of MDR1, and KRE6 upon interaction with dermal cells; both genes play significant roles in drug resistance and biofilm maturation, respectively. This study for the first-time shed light on the dominating defensive responses of human dermal cells, microbe colonization site, to C. auris biofilm and its toxic effects. Further, it demonstrates how C. auris biofilm responds to the defensive mechanisms developed by the human dermal cells.

Phosphorus (P) plays a crucial role in facilitating plant adaptation to cadmium (Cd) stress. However, the molecular mechanisms underlying P-mediated responses to Cd stress in roots remain elusive. This study investigates the effects of P on the growth, physiology, transcriptome, and metabolome of Salix caprea under Cd stress. The results indicate that Cd significantly inhibits plant growth, while sufficient P alleviates this inhibition. Under Cd exposure, P sufficiency resulted in increased Cd accumulation in roots, along with reduced oxidative stress levels (superoxide anion and hydrogen peroxide contents were reduced by 16.8% and 30.1%, respectively). This phenomenon can be attributed to the enhanced activities of antioxidant enzymes such as superoxide dismutase (SOD) and catalase (CAT), as well as increased levels of antioxidants including ascorbic acid (AsA) and flavonoids under sufficient P conditions. A total of 4208 differentially expressed genes (DEGs) and 552 differentially accumulated metabolites (DAMs) were identified in the transcriptomic and metabolomic analyses, with 2596 DEGs and 113 DAMs identified among treatments with different P levels under Cd stress, respectively. Further combined analyses reveal the potential roles of several pathways in P-mediated Cd detoxification, including flavonoid biosynthesis, ascorbate biosynthesis, and plant hormone signal transduction pathways. Notably, sufficient P upregulates the expression of genes including HMA, ZIP, NRAMP and CAX, all predicted to localize to the cell membrane. This may elucidate the heightened Cd accumulation under sufficient P conditions. These findings provide insights into the roles of P in enhancing plant resistance to Cd stress and improving of phytoremediation.

Colorectal cancer (CRC) is the fourth most common cancer among U.S. men and women and the second deadliest. Effective screening modalities can either prevent CRC or find it earlier, but fewer than two thirds of U.S. adults are adherent to CRC screening guidelines. We tested whether people who defensively avoid CRC information have lower adherence to CRC screening recommendations and weaker intentions for being screened and whether CRC information avoidance adds predictive ability beyond known determinants of screening. Participants, aged 45-75 years, completed a survey about known structural determinants of CRC screening (healthcare coverage, healthcare use, provider recommendation), CRC information avoidance tendencies, and screening behavior (n = 887) and intentions (n = 425). Models were tested with multivariable regression and structural equation modeling (SEM). To the extent that participants avoided CRC information, they had lower odds of being adherent to CRC screening guidelines (OR = 0.55) and if non-adherent, less likely to intend to be screened (b=-0.50). In the SEM model, avoidance was negatively associated with each known structural determinant of screening and with lower screening adherence (ps < 0.01). Fit was significantly worse for nested SEM models when avoidance was not included, (i.e., the paths to avoidance were fixed to zero). Information avoidance was associated with screening behavior and other known structural determinants of screening adherence, potentially compounding its influence. Novel strategies are needed to reach avoiders, including health communication messaging that disrupts avoidance and interventions external to the healthcare system, with which avoiders are less engaged.

OBJECTIVE: Patients with Post-Traumatic Stress Disorder (PTSD) present a variety of symptoms, with different intensities, causing impairments in the individual, social and occupational functioning areas. The aim of this study was to understand the psychodynamic functioning of patients with PTSD, exploring the relationship between symptom severity, quality of life, subjective suffering, conflicts and psychic structure regarding sociodemographic characteristics, styles and defensive mechanisms.
METHODS: This is a cross-sectional quantitative study with 60 participants. The following were used: sociodemographic questionnaire, the Operationalized Psychodynamic Diagnosis-2 (OPD-2) and the Defensive Style Questionnaire (DSQ-40).
RESULTS: Participants had moderate to high symptom severity, with significant subjective suffering and isolation. The main conflict was Need for care x Self-sufficiency and the level of Total Structure was moderate/low. The use of immature, neurotic, and mature defensive styles was observed. More primitive personality structures, more rigid defenses and greater dependence were found in patients with history of past trauma. Other mental disorders were also associated.
CONCLUSIONS: OPD-2 was effective to assess the psychodynamic functioning characteristics of patients with PTSD. Therapeutic treatment should focus on the psychic structure and not only on symptom control. Prevention strategies should target vulnerability factors and strengthening of protective factors.

UNASSIGNED: Non-suicidal self-injury (NSSI) is commonly seen in adolescents with depression and is a high-risk factor leading to suicide. The psychological mechanisms underlying depression with NSSI are still unclear. The purpose of this study was to explore the differences in personality traits, defensive styles, and borderline symptoms among first-episode youth patients with depression and self-injury compared with patients with depression without self-injury and healthy populations.
UNASSIGNED: The current study recruited 188 participants, including 64 patients with depression and NSSI, 60 patients with depression without NSSI, and 64 healthy control subjects. Eysenck Personality Questionnaire, the Defense Style Questionnaire, the short version of the Borderline Symptom List, the Beck Depression Inventory, and the Ottawa Self-Injury Inventory were used to assess all participants.
UNASSIGNED: Patients with depression and NSSI showed more psychoticism than patients with depression without NSSI and healthy control subjects. Patients with depression and NSSI presented more intermediate defense styles than healthy control subjects. In the patients with depression and NSSI group, the frequency of self-injury in the last week was negatively correlated with mature defense styles and positively correlated with depressive symptoms and borderline symptoms. Further regression analysis showed that EPQ-psychoticism and depressive symptoms were independent risk factors for NSSI in patients with depression.
UNASSIGNED: This study found that patients with depression and self-injury presented more neuroticism, introversion, EPQ-psychoticism, immature defenses, intermediate defenses, and borderline symptoms. Self-injury frequency was negatively correlated with mature defense styles and positively correlated with depressive symptoms and borderline symptoms. EPQ-Psychoticism and depressive symptoms are risk factors for predicting non-suicidal self-injury in patients with depression.

Polycyclic aromatic hydrocarbons (PAHs) are widespread, persistent environmental pollutants. They exert toxic effects at different developmental stages of plants. Plant defense mechanisms against PAHs are poorly understood. To this end, transcriptomics and widely targeted metabolomic sequencing were used to study the changes in gene expression and metabolites that occur in the roots of Salix viminalis subjected to phenanthrene stress. Significant variations in genes and metabolites were observed between treatment groups and the control group. Thirteen amino acids and key genes involved in their biosynthesis were upregulated exposed to phenanthrene. Cysteine biosynthesis was upregulated. Sucrose, inositol galactoside, and mellidiose were the main carbohydrates that were largely accumulated. Glutathione biosynthesis was enhanced in order to scavenge reactive oxygen species and detoxify the phenanthrene. Glucosinolate and flavonoid biosynthesis were upregulated. The production of pinocembrin, apigenin, and epigallocatechin increased, which may play a role in antioxidation to resist phenanthrene stress. In addition, levels of six amino acids and N,N\'-(p-coumaroyl)-cinnamoyl-caffeoyl-spermidine were significantly increased, which may have helped protect the plant against phenanthrene stress. These results demonstrated that S. viminalis had a positive defense strategy in response to phenanthrene challenge. Subsequent defense-related reactions may have also occurred within 24 h of phenanthrene exposure. The findings of the present study would be useful in elucidating the molecular mechanisms regulating plant responses to PAH challenges and would help guide crop and plant breeders in enhancing PAH resistance.
