RESUMO

Functional accounts of emotion have guided research for decades, with the core assumption that emotions are functional-they improve outcomes for people. Based on functional accounts of emotion, we theorized that anger should improve goal attainment in the presence of challenges. In seven studies, goal attainment was assessed in situations that involved varying levels of challenges to goal attainment. Across studies, anger compared to a neutral condition resulted in behavior that facilitated greater goal attainment on tasks that involved challenges. With a goal to solve difficult puzzles, anger resulted in more puzzles correctly solved (Study 1). With a goal to attain prizes, anger increased cheating rates and numbers of unearned prizes (Study 2). With a goal to do well in a video game, anger increased scores on a game with challenges to be avoided, but not other scores (Study 3). In two studies, examining the consequences of anger in response to the challenging task that was the focus of that anger, anger decreased reaction time with goals to win trials (Study 4), and predicted making the effort to vote in two contentious elections (Study 5). With a goal to protect financial resources, anger increased action taken to prevent loss compared to a physiological arousal condition (Study 6).

RESUMO

(1) Background: Disparities in cancer treatment and outcomes have long been well-documented in the medical literature. With the eruption of advances in new treatment modalities, the long-existing disparities are now being further uncovered and brought to the attention of the medical community. While social health determinants have previously been linked to treatment disparities in lung cancer, we analyzed data from the National Cancer Database to explore sociodemographic and geographic factors related to accepting or declining physician-recommended chemotherapy. Patients diagnosed with metastatic lung cancer between 2004 and 2016 who declined chemotherapy recommended by their physicians were included in this study. Multivariate logistic regression analysis was performed. Cox Regression and Kaplan-Meier analyses were performed to look for survival characteristics. (2) Results: 316,826 patients with Stage IV lung cancer were identified. Factors related to a higher rate of refusal by patients included older age > 70, female sex, low income, lack of insurance coverage, residency in the New England region, and higher comorbidity. Patients living in areas with lower education were less likely to decline chemotherapy. (3) Conclusion: Further understanding of the factors impacting treatment decisions would be essential to improve the efficacy of care delivery in patients with cancer and reduce reversible causes of disparity.

RESUMO

Epigenetic ("above genetics") modifications can alter the gene expression without altering the DNA sequence. Aberrant epigenetic regulations in cancer include DNA methylation, histone methylation, histone acetylation, non-coding RNA, and mRNA methylation. Epigenetic-targeted agents have demonstrated clinical activities in hematological malignancies and therapeutic potential in solid tumors. In this review, we describe mechanisms of various epigenetic modifications, discuss the Food and Drug Administration-approved epigenetic agents, and focus on the current clinical investigations of novel epigenetic monotherapies and combination therapies in solid tumors.

RESUMO

BACKGROUND: Some cancer patients who are diagnosed with thromboembolism may require dual treatment with vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs) and factor Xa inhibitors (low-molecular-weight heparin [LMWH] or direct oral anticoagulants [DOACs]). However, to the authors' knowledge, the safety of such combinations has not been well characterized. METHODS: Patients with advanced cancer who were treated with concurrent VEGFR TKIs and factor Xa inhibitors between 2010 and 2018 at The Ohio State University Comprehensive Cancer Center were included. Charts were reviewed retrospectively for clinically significant bleeding events occurring during concurrent treatment compared with those occurring during factor Xa inhibitor therapy alone, using each patient as their own control. The Fisher exact test was used to compare distribution of bleeding severities. The Cox proportional hazards model was used to compare bleeding risk between groups. RESULTS: Among 86 patients, there were 29 clinically significant bleeding events (including 8 major bleeding events) reported during concurrent treatment and 17 events (including 4 major bleeding events) reported during factor Xa inhibitor therapy alone over a median follow-up of 63 days. Concurrent treatment was associated with significantly higher risks of overall bleeding (hazard ratio, 2.45; 95% confidence interval, 1.28-4.69 [P = .007]) and first-onset bleeding (hazard ratio, 2.23; 95% confidence interval, 1.13-4.42 [P = .02]). Analysis of 6-month bleeding risk and the subgroups of patients treated with concurrent TKIs and LMWH versus LMWH alone demonstrated a similar trend. The sample size was inadequate for comparisons between treatment with concurrent TKIs and DOACs versus DOACs alone. CONCLUSIONS: Concurrent treatment with VEGFR TKIs and LMWH was found to be associated with a significantly increased risk of bleeding events when compared with LMWH therapy alone.

RESUMO

Elderly women with early-stage, nonmetastatic breast cancer do not always receive recommendations for definitive surgical treatment. The reasons vary and include patient and provider-related reasons.We queried the surveillance, epidemiology, and end results database from 2010 to 2013 for women age 60 and older with stage I/II/III invasive breast cancer for whom local treatment was known. We divided the patients into 3 groups: patients for whom surgery was performed; patients for whom surgery was recommended but not performed; patients for whom surgery was not recommended and not performed. We used Kaplan-Meier method to generate OS curves and the Cox proportional hazard test to compare survival outcomes.A total of 119,404 patients were eligible for study with a median age between 70 and 74 years old. Compared with patients who received breast surgery, patients who did not receive surgery had a worse overall survival (OS) (hazard ratio [HR], 7.39; 95% confidence interval [CI], 6.98-7.83, P < .001). Patients who were recommended but ultimately did not undergo surgery had better OS than those who were recommended against surgery (adjusted HR, 0.60; 95% CI, 0.53-0.69). However, their survival was significantly inferior to patients who underwent surgery (adjusted HR, 2.81; 95% CI 2.48-3.19). Similar results were found regardless of age, tumor stage, estrogen receptor, or human epidermal growth factor receptor 2 status and were recapitulated in analyses of cancer-specific survival.Upfront definitive breast surgery should be performed in medically-fit elderly patients with early-stage, nonmetastatic breast cancer given significant survival benefit.

RESUMO

Improving methods for assessing the spatial and temporal resolution of organic compound concentrations in marine environments is important to the sustainable management of our coastal systems. Here we evaluate the use of ethylene vinyl acetate (EVA) as a candidate polymer for thin-film passive sampling in waters of marine environments. Log K(EVA-W) partition coefficients correlate well (r(2) = 0.87) with Log K(OW) values for selected pesticides and polychlorinated biphenyls (PCBs) where Log K(EVA-W) = 1.04 Log K(OW) + 0.22. EVA is a suitable polymer for passive sampling due to both its high affinity for organic compounds and its ease of coating at sub-micron film thicknesses on various substrates. Twelve-day field deployments were effective in detecting target compounds with good precision making EVA a potential multi-media fugacity meter.

RESUMO

Plasmacytoid dendritic cells (pDCs) play essential roles in directing immune responses. These cells may be particularly important in determining the nature of immune responses to viral infections in patients with allergic asthma as well those with other atopic diseases. The purposes of this study were 1) to compare the functional capacity of pDCs in patients with one type of allergic disorder, allergic asthma, and controls; 2) to determine whether IgE cross-linking affects antiviral responses of influenza-exposed pDCs; and 3) to determine whether evidence of counterregulation of FcepsilonRIalpha and IFN-alpha pathways exists in these cells. pDC function was assessed in a subset of asthma patients and in controls by measuring IFN-alpha production after exposure of purified pDCs to influenza viruses. FcepsilonRIalpha expression on pDCs was determined by flow cytometry in blood samples from patients with allergic asthma and controls. pDCs from patients with asthma secreted significantly less IFN-alpha upon exposure to influenza A (572 versus 2815; p = 0.03), and secretion was inversely correlated with serum IgE levels. Moreover, IgE cross-linking prior to viral challenge resulted in 1) abrogation of the influenza-induced pDC IFN-alpha response; 2) diminished influenza and gardiquimod-induced TLR-7 upregulation in pDCs; and 3) interruption of influenza-induced upregulation of pDC maturation/costimulatory molecules. In addition, exposure to influenza and gardiquimod resulted in upregulation of TLR-7, with concomitant downregulation of FcepsilonRIalpha expression in pDCs. These data suggest that counterregulation of FcepsilonRI and TLR-7 pathways exists in pDCs, and that IgE cross-linking impairs pDC antiviral responses.

RESUMO

The impact of IFN-alpha secretion on disease progression was assessed by comparing phenotypic changes in the lupus-prone B6.Sle1Sle2Sle3 (B6.Sle123) strain and the parental C57BL/6 (B6) congenic partner using an adenovirus (ADV) expression vector containing a recombinant IFN-alpha gene cassette (IFN-ADV). A comprehensive comparison of cell lineage composition and activation in young B6 and B6.Sle123 mice revealed a variety of cellular alterations in the presence and absence of systemic IFN-alpha. Most IFN-alpha-induced phenotypes were similar in B6 and B6.Sle123 mice; however, B6.Sle123 mice uniquely exhibited increased B1 and plasma cells after IFN-alpha exposure, although both strains had an overall loss of mature B cells in the bone marrow, spleen and periphery. Although most of the cellular effects of IFN-alpha were identical in both strains, severe glomerulonephritis occurred only in B6.Sle123 mice. Mice injected with IFN-ADV showed an increase in immune complex deposition in the kidney, together with an unexpected decrease in serum anti-nuclear antibody levels. In summary, the predominant impact of systemic IFN-alpha in this murine model is an exacerbation of mechanisms mediating end organ damage.
