RESUMO

Adults diagnosed with major depressive disorder (MDD) have been found to be characterized by selective attention to negative material and by impairments in their ability to disengage from, or inhibit the processing of, negative stimuli. Altered functioning in the frontal executive control network has been posited to underlie these deficits in cognitive functioning. We know little, however, about the neural underpinnings of inhibitory difficulties in depressed adolescents. We used functional magnetic resonance imaging in 18 adolescents diagnosed with MDD and 15 age- and gender-matched healthy controls (CTLs) while they performed a modified affective Go/No-Go task that was designed to measure inhibitory control in the presence of an emotional distractor. Participants were presented with either a happy or a sad face, followed by a go or a no-go target to which they either made or inhibited a motor response. A group (MDD, CTL) by valence (happy, sad) by condition (go, no-go) analysis of variance indicated that MDD adolescents showed attenuated BOLD response in the right dorsolateral prefrontal cortex (DLPFC) and in the occipital cortex bilaterally, to no-go targets that followed a sad, but not a happy, face. Adolescents diagnosed with MDD showed anomalous recruitment of prefrontal control regions during inhibition trials, suggesting depression-associated disruption in neural underpinnings of the inhibition of emotional distractors. Given that the DLPFC is associated with the maintenance of goal-relevant information, it is likely that sad faces differentially capture attention in adolescents with MDD and interfere with task demands requiring inhibition.

RESUMO

PURPOSE: Black women with breast cancer often present with more aggressive disease compared with other races, contributing to an increased risk of cancer mortality. Despite this inequity, Black women remain severely underrepresented in breast cancer clinical trials. We aim to characterize factors that influence a woman's decision to enroll in a clinical trial, with the goal of identifying clinical interventions to aid in the recruitment of vulnerable groups. METHODS AND MATERIALS: A cross-sectional, descriptive study was conducted using a questionnaire adapted from 2 prevalidated surveys investigating factors influencing clinical trial enrollment. The survey was administered to women with curable breast cancer during a single follow-up visit at 4 different sites within a university medical system where all patients are screened for clinical trial eligibility. Chi-square tests and Mann-Whitney U tests were used to assess associations or differences between the populations. RESULTS: One hundred ninety-four out of 209 women completed the survey, giving a compliance rate of 93%. Twenty-six percent of women self-identified as Black, most women were located at community sites (67.1%), most women had diagnoses of early-stage disease (I: 57.7%, II: 29.4%), and 81% of women had some collegiate-level education. Black women were younger at diagnosis (P = .005) and less likely to be married (P = .012) but more often lived with family members (P = .003) and had a lower median income (P < .001). According to the survey, Black women were less likely to trust their care team (P = .032), more likely to believe that research ultimately harms minorities (P < .001), and had a stronger belief in God's will determining illness and wellness (P < .001). Recurring themes of trust in the health care team, patient education, and advancement of cancer treatments were discussed in the focus groups. CONCLUSIONS: Failure to offer clinical trials and mistrust in research institutions may pose the greatest hindrances to the enrollment of Black women in clinical trials. Empowering women through education and fostering trustworthy relationships can encourage greater clinical trial participation.

RESUMO

PURPOSE: There are little data quantifying the psychosocial needs of patients with cancer undergoing definitive radiation therapy. These needs significantly affect patients' access to care and treatment outcomes. Thus, our study aimed to characterize the socioeconomic needs of patients with cancer treated at an academic institution in urban and suburban radiation clinics. METHODS AND MATERIALS: A prospective, cross-sectional analysis was performed of patients undergoing curative radiation therapy for head and neck, lung/thoracic, gynecologic, or gastrointestinal malignancies using a questionnaire consolidated from prevalidated surveys. Main outcomes were differences in psychosocial needs stratified by race (Black vs non-Black) and time point (pretreatment, 1 month, 6 months, and 1 year after completion of radiation treatment). χ2 and Mann-Whitney U testing determined statistical differences between selected variables. Binary logistic regression analysis identified predictors of certain socioeconomic needs. RESULTS: Two hundred twenty-one of 266 patients completed the survey, giving a compliance rate of 83%. Black patients were more likely to be single (79% vs 37%; P < .001), reside in zip codes with a lower median income (74% vs 42%; P < .001), and be seen at our inner-city photon location (60% vs 25%; P < .001) compared with non-Black patients. Significantly higher proportions of Black compared with non-Black patients had unmet needs regarding pain (67% vs 39%; P = .005), stress management (64.7% vs 43.3%; P = .009), transportation (64% vs 19%; P < .001), and smoking cessation (35% vs 8.7%; P < .001) when all time points were considered. On multivariate analysis, Black patients were 2.6, 2.2, 7.2, and 3.4 times more likely than non-Black patients to request assistance with pain, stress, transportation, and financial aid, respectively. CONCLUSIONS: We identified disparate psychosocial needs of our cancer population, where Black patients had greater unmet needs than non-Black patients. By doing so, we plan to develop pragmatic, targeted interventions that, when combined with guideline-concordant cancer care, can lead to improvements in cancer outcomes and quality of life before, during, and after radiation therapy.

RESUMO

BACKGROUND: The Extended Prostate Cancer Index Composite (EPIC) instrument is a commonly used patient reported outcome (PRO) tool in prostate cancer clinical trials. Summary scores for EPIC subscales are calculated by averaging patient scores for attributes (e.g., side effects), implying equal weighting of the attributes in the absence of evidence showing otherwise. METHODS: We estimated patient preferences for each of the attributes included in the bowel subscale of the EPIC instrument using best-worst (B-W) scaling among a cohort of men with prostate cancer. Patients were presented with multiple tasks in which they were asked to indicate which attribute they would find most and least bothersome at different levels of severity. Analysis utilized both (simple) B-W counts and scores to estimate patient preferences for each attribute as well as attribute levels. RESULTS: A total of 174 respondents from two institutions participated in the survey. Preference estimates for each of the five attributes included in the EPIC-26 bowel subscale showed wide variation preferences: 'losing control of bowel movements' was found to be the most bothersome attribute, with a B-W score of -0.48, followed by bowel urgency which also had negative B-W score (-0.04). Increased frequency of bowel movements was the least bothersome attribute, with a B-W score of +0.33, followed by bloody stools (+0.12), and pelvic/rectal pain (+0.06). Analysis of preference weights for attribute bother levels showed preference estimates be linear. CONCLUSIONS: We provide novel evidence on patient preferences for side effect reduction following prostate radiotherapy. Within the bowel sub-scale of the EPIC-26 short form, we found that bowel incontinence was perceived to be the most bothersome treatment effect, while increased bowel frequency was least bothersome to patients.

RESUMO

Depressed adolescents are characterized by negative interpretation biases. Although investigators have used cognitive bias modification for interpretation (CBM-I) to experimentally manipulate interpretation biases in depressed adults, the near- and far-transfer effects are not well understood in adolescents diagnosed with Major Depressive Disorder (MDD). In this study, we extend previous research by investigating the near- and far-transfer effects of 6 sessions of Positive versus Neutral CBM-I on independent measures of interpretation bias (near-transfer effects) and on attention biases and clinical symptoms (far-transfer effects) in a sample of adolescents with MDD (n = 46). At post-training, adolescents who received Positive CBM-I interpreted ambiguous scenarios more positively than did participants who received Neutral CBM-I, providing evidence of training effectiveness. There was no evidence, however, of near- or far-transfer effects. These findings raise concerns about the malleability of interpretation biases in adolescent depression and suggest that further work is needed to establish the clinical utility of CBM-I for adolescents with MDD.

RESUMO

BACKGROUND: Individuals with Major Depressive Disorder (MDD) are characterized by biases in attention to negative emotional material. While there is evidence that anomalous functioning in frontocingulate regions may underlie these biases, we know little about the neural correlates of negative emotional biases in depressed adolescents. METHODS: Eighteen adolescents diagnosed with MDD and 21 matched healthy control (CTL) adolescents underwent fMRI while performing an emotional distractor task. On each trial participants were presented with task-relevant house pairs and task-irrelevant face pairs. Participants indicated whether the house pairs were identical while ignoring the face pairs, which were either fearful, sad, or neutral. RESULTS: Despite equivalent behavioral performance (response time and accuracy) between groups, adolescents with MDD exhibited greater activation in frontocingulate regions, including dorsal anterior cingulate cortex (dACC) and inferior frontal gyrus/middle frontal gyrus (IFG/MFG), and occipitoparietal regions, including lateral occipital cortex and superior parietal lobule when ignoring fearful versus neutral faces. Response times to these trial conditions also correlated negatively with activation in IFG/MFG and lateral occipital cortex suggesting these regions are recruited in order to effectively ignore emotional distractors. Groups did not differ when ignoring sad versus neutral faces or fearful versus sad faces. CONCLUSIONS: Adolescents with MDD recruit both cognitive control and visual attention regions to a greater degree than do CTL adolescents, reflecting greater cognitive demand when downregulating threat-related stimuli.
