The promoter of prosocial behavior in fighting against the COVID-19 pandemic needs to be examined. Here, we examined the effect of experienced awe through cross-sectional (Study 1), a 3-wave longitudinal (Study 2) and experimental (Study 3–4) approaches. Study 1 showed that dispositional awe positively predicted one's prosocial behavior in the pandemic (N = 1281). Study 2 (N = 332) observed that experienced awe predicted higher prosociality, and this relationship was serially mediated by connectedness and empathy. Study 3 (N = 153) and 4 (N = 156) confirmed that elicited awe, compared to that of amusement and neutrality, promoted multiple types of prosociality (Study 3) and willingness of blood donation (Study 4) via serial mediation of connectedness and empathy. These findings suggest that the experience of awe increases one's connectedness to the world, which in turn enhances empathic concern and prosociality in pandemic fighting. [ABSTRACT FROM AUTHOR]

Human adipose-derived stem cells (ADSCs) have become a promising therapeutic approach against skin aging. Recent studies confirm that exosomes partially mediate the therapeutic effect of stem cells. This study successfully isolated exosomes from the ADSC culture medium and discovered that ADSC-derived exosomes (ADSC-Exos) could alleviate human dermal fibroblast (HDF) senescence and stimulate HDF migration. Moreover, ADSC-Exos increased the type I collagen expression level and reduced the reactive oxygen species (ROS) and senescence-associated β-galactosidase (SA-β-Gal) activity in HDFs. In addition, we demonstrated that ADSC-Exos significantly inhibited senescence-related protein expression levels of p53, p21, and p16. In conclusion, our results have revealed the antisenescence effects of ADSC-Exos on HDFs and ADSC-Exos may be a novel cell-free therapeutic tool for antiaging. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to summarize the current evidence-based approach to perioperative enteral nutritional (EN) program for gastric cancer (GC) surgery and to develop a staged and operable EN management scheme based on the evidence to provide clinical guidance for improving perioperative EN management in patients with GC. Methods: First, we synthesized expert consensuses, systematic reviews, and guidelines related to GC patients who had undergone surgery, based on a review of the literature and expert meetings. Subsequently, after carefully evaluating and selecting relevant EN management data, we created a preliminary draft of a perioperative EN program. Following Delphi expert consultations, the final version of the perioperative EN program was constructed after revision. Results: After two rounds of consultation, the expert opinions tended to be consistent. The expert positive coefficient was 1.00, and the expert authority coefficient was 0.90. After the second round of consultation, the coefficient of variation of the importance score ranged from 0.05 to 0.20, and the coefficient of variation of the feasibility score ranged from 0.09 to 0.23. The Kendall harmony coefficients were 0.338 and 0.392, and the difference between them was statistically significant (p < 0.001). The final practice plan includes 4 first-level, 16 s-level, and 64 third-level items. Conclusions: The perioperative EN program constructed in this study is comprehensive in content, feasible, and evidence-based, and can provide insights for clinical improvement.

GINS2 is overexpressed in several cancers, but little is known about its role in osteosarcoma (OS). A series of in vivo and in vitro experiments were conducted to explore the role of GINS2 in OS. In this study, we demonstrated that GINS2 was found to be highly expressed in OS tissues and cell lines, which was associated with poor outcomes in OS patients. GINS2 knockdown hindered the growth and induced apoptosis in OS cell lines in vitro. Furthermore, GINS2 knockdown effectively inhibited the growth of a xenograft tumor in vivo. By using an Affymetrix gene chip and intelligent pathway analysis, it was demonstrated that the GINS2 knockdown could reduce the expression of several targeted genes and reduce the activity of the MYC signaling pathway. Mechanically, LC-MS, CoIP, and rescue experiments revealed that GINS2 promoted tumor progression through the STAT3/MYC axis in the OS. Moreover, GINS2 was associated with tumor immunity and may be a potential immunotherapeutic target for OS. [ABSTRACT FROM AUTHOR]

Introduction: Subjective cognitive decline (SCD) is a self-reported cognitive decline without objective cognitive impairment. The relationship between audiometric hearing loss (HL) and cognitive function has not been reported in SCD. The purpose of this study was to investigate whether HL affects cognition-related indexes in SCD individuals. Methods: This is a cross-sectional study that used the baseline data of a multicenter cohort study that monitors clinical progression from SCD to dementia. Individuals aged ≥60 years who reported cognitive decline but had no objective cognitive impairment on comprehensive neuropsychological tests were recruited. Participants were grouped into the normal-hearing (NH) and bilateral HL groups. The demographics, clinical characteristics, dementia biomarkers, global cognition, questionnaire scores, neuropsychological test scores, and segmental brain volumes from MRI were compared between the groups. Results: Of a total of 120 participants, one hundred and two had NH (n = 57) or bilateral HL (n = 45). There were no group differences in the demographic and clinical data except the age. The biomarkers, global cognition, and questionnaire scores were not different between the groups. The HL group performed worse (the z-score of −0.06) in the Stroop Color Word Test than the NH group (0.27) (p = 0.025). Brain volumetric analysis revealed that the HL group had reduced gray matter volumes in four brain subregions: left temporal pole, left caudal middle frontal gyrus, left hippocampus, and right isthmus of the cingulate gyrus. Conclusion: In SCD, HL exerted an adverse effect on cognitive function, primarily frontal executive function tested in the Stroop task. HL was also related to gray matter volume reductions in brain subregions, although causality needs further investigation. This study may provide evidence for a potential link between hearing and cognition in SCD, an emerging clinical entity. [ABSTRACT FROM AUTHOR]

Self-management is essential for patients who require regular hemodialysis treatment. This study aimed to explore the relationships between social support, sense of coherence (SOC), and self-management in hemodialysis patients and to examine whether SOC plays a mediating role. In a cross-sectional study, 402 hemodialysis patients from four tertiary hospitals were recruited. Data were analyzed using structural equation modeling. Social support, SOC, and self-management were significantly correlated with each other. The proposed model provided a good fit to the data. Social support had a direct effect on self-management and SOC, partially mediated the effect of social support on self-management (β = 0.248, p = 0.001). Social support and SOC explained 69% of the variance in self-management. Our findings indicate that health care providers can enhance social support with an emphasis on strengthening SOC strategies to better improve self-management in hemodialysis patients.
