Front Pharmacol 2021; 12:632045. [PMID: 34489690 PMCID: PMC8417776 DOI: 10.3389/fphar.2021.632045] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 06/24/2021] [Indexed: 01/01/2023] Open
Abstract
Background: Cholangiofibrosis is a controversial intrahepatic cholangial lesion that precedes the development of cholangiocarcinoma. Here, we demonstrate that molecular hydrogen (H2) can be used to effectively prevent cholangiofibrosis. Methods: The safety and quality of life (QOL) of rats was firstly evaluated. H2 was administered to rats subjected to thioacetamide (TAA)-induced cholangiofibrosis throughout the whole process. Then, rats were administrated with TAA for 3 months and then followed by H2 intervention. Rat livers were harvested and assessed by light microscopy and convolutional neural network. RNA-seq was performed to analyze the genetic changes in these animal models. Results: Continuous use of H2-rich water was safe and improved QOL.The incidence and average number of cholangiofibrosis in the liver were higher in the TAA group (100%, 12.0 ± 10.07) than that in the H2 group (57.1%, 2.86 ± 5.43). The AI algorithm revealed higher Alesion/Aliver in the TAA group (19.6% ± 9.01) than that in the H2 group (7.54% ± 11.0). RNA-seq analysis revealed that H2 results in a decline in glycolysis. Moreover, in the third experiment, the incidence of microscopic or suspicious tumors and the ratio of liver lesions was decreased after long-term use of H2 (12.5%, 0.57% ± 0.45) compared with untreated group (100%, 0.98% ± 0.73). A number of intestinal microbiota was changed after H2 usage, including clostridiaceae_1, ruminococcus, turicibacter, coriobacteriales, actinobacteria, and firmicutes_bacterium. Conclusion: Hydrogen-rich water protects against liver injury and cholangiofibrosis and improved quality of life partially through regulating the composition of intestinal flora.

Cancer 2020; 126:1512-1521. [PMID: 31869452 PMCID: PMC7178109 DOI: 10.1002/cncr.32670] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Revised: 11/17/2019] [Accepted: 11/26/2019] [Indexed: 01/07/2023]
Abstract
BACKGROUND To the authors' knowledge, studies regarding risk perception among survivors of thyroid cancer are scarce. METHODS The authors surveyed patients who were diagnosed with differentiated thyroid cancer from the Surveillance, Epidemiology, and End Results registries of Georgia and Los Angeles County (2632 patients; 63% response rate). The analytic cohort was defined by a ≤5% risk of disease recurrence and mortality (1597 patients). Patients estimated their recurrence and mortality risks separately (increments of 10% and endpoints of ≤5% and ≥95%). Both outcomes were dichotomized between reasonably accurate estimates (risk perception of ≤5% or 10%) versus overestimation (risk perception of ≥20%). Multivariable logistic regression was used to identify factors associated with risk overestimation, and the relationships between overestimation and both worry and quality of life were evaluated. RESULTS In the current study sample, 24.7% of patients overestimated their recurrence risk and 12.5% overestimated their mortality risk. A lower educational level was associated with overestimating disease recurrence (≤high school diploma: odds ratio [OR], 1.64 [95% CI, 1.16-2.31]; and some college: OR, 1.36 [95% CI, 1.02-1.81]) and mortality (≤high school diploma: OR, 1.86 [95% CI, 1.18-2.93]) risk compared with those attaining at least a college degree. Hispanic ethnicity was found to be associated with overestimating recurrence risk (OR, 1.44, 95% CI 1.02-2.03) compared with their white counterparts. Worry about recurrence and death was found to be greater among patients who overestimated versus those who had a reasonably accurate estimate of their risk of disease recurrence and mortality, respectively (P < .001). Patients who overestimated mortality risk also reported a decreased physical quality of life (mean T score, 43.1; 95% CI, 41.6-44.7) compared with the general population. CONCLUSIONS Less educated patients and Hispanic patients were more likely to report inaccurate risk perceptions, which were associated with worry and a decreased quality of life.

Abstract
BACKGROUND Breast cancer worries are important determinants in relation to behavior favoring breast cancer screening. OBJECTIVE To determine the effect of theory-based training to promote breast cancer screening among women with high and low levels of breast cancer worries. DESIGN AND SETTING Randomized controlled trial, conducted in two family health centers. METHODS In total, 285 women were recruited. Women with low levels of breast cancer worries were included in the first intervention group (112 women) and the first control group (112 women), while women with high levels of breast cancer worries were included in the second intervention group (37 women) and the second control group (43 women). Theory-based training to promote breast cancer screening was given to intervention groups. The women's willingness to undergo breast cancer screening and breast cancer worry scores were evaluated at 1, 3 and 6 months. RESULTS The women in the low cancer-worry intervention group performed breast self-examination more in months 1 and 6 following the training, and the women in the high cancer-worry control group performed breast self-examination more in month 3 (P < 0.05). No difference between the women who had low or high levels of breast cancer worries were observed in relation to breast self-examination, clinical breast examination or mammography (P > 0.05). CONCLUSION The level of worry did not affect the success of theory-based training, and the training was partially effective with regard to willingness to undergo breast cancer screening.

Abstract
BACKGROUND Menopause predisposes individuals to affective disorders, such as depression, which is tightly related to neuroinflammation. While the neuroinflammatory condition has been demonstrated in ovariectomized (OVX) rodents, there is limited evidence concerning microglial polarization, a key process in brain immune activation, in menopause-related brain. METHODS Therefore, the present study aims to evaluate the polarized microglia in long-term OVX rats and we further explored whether supplementation of ω-3 polyunsaturated fatty acids (PUFA), the pleiotropic bioactive nutrient, is effective in the neurobehavioral changes caused by OVX. RESULTS Our data showed that OVX-induced anxiety and depression-like behaviors in rats, accompanied with increased neural apoptosis and microglial activation in the hippocampus. Additionally, OVX enhanced proinflammatory cytokines expression and suppressed the expression of anti-inflammatory cytokine, IL-10. Correspondingly, OVX reinforced NFκB signaling and shifted the microglia from immunoregulatory M2 phenotype to proinflammatory M1 phenotype. Meanwhile, daily supplementation with PUFA suppressed microglial M1 polarization and potentiated M2 polarization in OVX rats. In parallel, PUFA also exerted antidepressant and neuroprotective activities, accompanied with neuroimmune-modulating actions. CONCLUSION Collectively, the present study firstly demonstrated the disturbed microglial polarization in the OVX brain and provide novel evidence showing the association between the antidepressant actions of PUFA and the restraint neuroinflammatory progression.

Abstract
BACKGROUND Risk perception is a multidimensional phenomenon that describes the individual's judgment of the likelihood of experiencing something unpleasant. Risk perception helps to understand how rheumatoid arthritis patients perceive disease-related-risks. We developed and validated a risk perception questionnaire for Spanish speaking rheumatoid arthritis patients. METHODS The questionnaire development and validation was performed in 3 steps, using respective convenience samples. Step-1 included the conceptual model construction, 20 patient's interviews to identify components from the conceptual model-dimensions and 11 healthcare provider´s consultations who identified RA related manifestations/complications (network and frequencies analysis). Step-2 consisted of item generation and reduction and questionnaire feasibility (n = 100). Step-3 consisted of the questionnaire psychometric validation (n = 270), which included content, face, construct (exploratory factor analysis) and criterion validity (logistic regression analysis) and consistency and stability (Cronbach's α and test-retest). RESULTS Samples were representative of typical RA outpatients. Initial conceptual model included 7 dimensions, 3 for probability and 1 each, for responsibility, prevention, control and for severity (Step-1). The final version was considered feasible by the patients and included 27 items (Step-2). A five-factor model was most appropriated and resulted in 68.8% of the variance explained: Cronbach's α = 0.90, intraclass-correlation-coefficient = 0.93 (95% CI = 0.90-0.95). A positive relation between number of external criteria from the charts and risk perception was found; all items had ≥80% agreement from experts; patients agreed about item´s semantic clarity (89%) and format adequacy (97%), (Step-3). CONCLUSIONS The risk perception questionnaire was valid and reliable to evaluate risk perception construct in RA outpatients; it can be incorporated to routine care and clinical research, and guide interventions to improve patient's health behaviors.
