Abstract

Introduction: Cancer survivors experienced poorer health-related quality of life (HRQoL) and greater psychological distress during the COVID-19 pandemic than those without cancer. However, the underlying mechanisms that may explain how negative experiences during the pandemic are associated with distress and HRQoL remain unknown. We examined whether psychosocial risk factors (i.e., healthcare disruption, disruption to daily activities and social interaction [DDASI], and financial hardship) mediated the relationship between negative COVID-19-related experiences and cancer survivors' HRQoL and psychological distress (i.e., depressive symptoms, and anxiety) and whether the mediating effects were moderated by psychosocial protective factors (i.e., stress management ability and social support). Methods: A total of 9,651 cancer survivors completed a questionnaire assessing negative COVID-19-related experiences, psychosocial and practical experiences, and HRQoL. Conditional process analysis was used to evaluate the proposed moderated mediation models. Results: Participants had a mean age of 63.8 years (SD = 12.3) and were mostly non-Hispanic White (82.3%). DDASI and financial hardship mediated the relationship between negative COVID-19-related experiences and cancer survivor's HRQoL and psychological distress. Stress management ability buffered the indirect effect of DDASI on cancer survivors' HRQoL and psychological distress. Social support buffered the indirect effect of financial hardship on HRQoL and depressive symptoms. Conclusion: Financial resources and social interactions may buffer negative effects of major disruptions such as the COVID-19 pandemic. Future studies should assess the longitudinal impact of these associations. [ABSTRACT FROM AUTHOR]

Abstract

Background Electrocorticography (ECoG) language mapping is often performed extraoperatively, frequently involves offline processing, and relationships with direct cortical stimulation (DCS) remain variable. We sought to determine the feasibility and preliminary utility of an intraoperative language mapping approach guided by real-time visualization of electrocorticograms. Methods A patient with astrocytoma underwent awake craniotomy with intraoperative language mapping, utilizing a dual iPad stimulus presentation system coupled to a real-time neural signal processing platform capable of both ECoG recording and delivery of DCS. Gamma band modulations in response to 4 language tasks at each electrode were visualized in real-time. Next, DCS was conducted for each neighboring electrode pair during language tasks. Results All language tasks resulted in strongest heat map activation at an electrode pair in the anterior to mid superior temporal gyrus. Consistent speech arrest during DCS was observed for Object and Action naming tasks at these same electrodes, indicating good correspondence with ECoG heat map recordings. This region corresponded well with posterior language representation via preoperative functional MRI. Conclusions Intraoperative real-time visualization of language task-based ECoG gamma band modulation is feasible and may help identify targets for DCS. If validated, this may improve the efficiency and accuracy of intraoperative language mapping. [ABSTRACT FROM AUTHOR]

Abstract

Background: Chemotherapy‐induced peripheral neuropathy (CIPN) includes negative sensations that remain a major chronic problem for cancer survivors. Previous research demonstrated that neurofeedback (a closed‐loop brain–computer interface [BCI]) was effective at treating CIPN versus a waitlist control (WLC). The authors' a priori hypothesis was that BCI would be superior to placebo feedback (placebo control [PLC]) and to WLC in alleviating CIPN and that changes in brain activity would predict symptom report. Methods: Randomization to one of three conditions occurred between November 2014 and November 2018. Breast cancer survivors no longer in treatment were assessed at baseline, at the end of 20 treatment sessions, and 1 month later. Auditory and visual rewards were given over 20 sessions based on each patient's ability to modify their own electroencephalographic signals. The Pain Quality Assessment Scale (PQAS) at the end of treatment was the primary outcome, and changes in electroencephalographic signals and 1‐month data also were examined. Results: The BCI and PLC groups reported significant symptom reduction. The BCI group demonstrated larger effect size differences from the WLC group than the PLC group (mean change score: BCI vs. WLC, −2.60 vs. 0.38; 95% confidence interval, −3.67, −1.46 [p =.000; effect size, 1.07]; PLC, −2.26; 95% confidence interval, −3.33, −1.19 [p =.001 vs. WLC; effect size, 0.9]). At 1 month, symptoms continued to improve only for the BCI group. Targeted brain changes at the end of treatment predicted symptoms at 1 month for the BCI group only. Conclusions: BCI is a promising treatment for CIPN and may have a longer lasting effect than placebo (nonspecific BCI), which is an important consideration for long‐term symptom relief. Although scientifically interesting, the ability to separate real from placebo treatment may not be as important as understanding the placebo effects differently from effects of the intervention. Plain Language Summary: Chemotherapy‐induced nerve pain (neuropathy) can be disabling for cancer survivors; however, the way symptoms are felt depends on how the brain interprets the signals from nerves in the body.We determined that the perception of neuropathy can be changed by working directly with the brain.Survivors in our trial played 20 sessions of a type of video game that was designed to change the way the brain processed sensation and movement.In this, our second trial, we again observed significant improvement in symptoms that lasted after the treatment was complete. The current results demonstrated that a brain–computer interface was an effective treatment for chemotherapy‐induced peripheral neuropathy, with benefits maintained at the 1‐month follow‐up. Although scientifically interesting, the ability to separate real from placebo treatment may not be clinically helpful to obtain longer term significant relief for cancer survivors.

Abstract

This study sought to determine if there was an association between prognostic-based serum biomarkers, survival, and psychosocial factors in patients with metastatic renal cell carcinoma. Associations were found between psychosocial factors and biomarker levels (hemoglobin with depressive symptoms (r = -0.29), positive affect (r = 0.30), social support (r = 0.19), and perceived stress (r = -0.27); albumin with depressive symptoms (r = -0.19), positive affect (r = 0.22), and social support (r = 0.20); alkaline phosphatase with depressive symptoms (r = 0.21), all p values Keywords Positive affect * Cancer * Depression * Biopsychosocial * Positive psychology * Survival, Introduction The majority of research in health psychology has focused on patients' negative psychological states or traits after diagnosis of diseases, including cancer (Reiche et al. 2005; Thaker et al.
