ABSTRACT
BACKGROUND: Up to 50% of people scheduled for screening colonoscopy do not complete this test and no studies have focused on minority and low-income populations. Interventions are needed to improve colorectal cancer (CRC) screening knowledge, reduce barriers, and provide alternative screening options. Patient navigation (PN) and tailored interventions increase CRC screening uptake, however there is limited information comparing their effectiveness or the effect of combining them. PURPOSE: Compare the effectiveness of two interventions to increase CRC screening among minority and low-income individuals who did not attend their screening colonoscopy appointment-a mailed tailored digital video disc (DVD) alone versus the mailed DVD plus telephone-based PN compared to usual care. METHODS: Patients (n = 371) aged 45-75 years at average risk for CRC who did not attend a screening colonoscopy appointment were enrolled and were randomized to: (i) a mailed tailored DVD; (ii) the mailed DVD plus phone-based PN; or (iii) usual care. CRC screening outcomes were from electronic medical records at 12 months. Multivariable logistic regression analyses were used to study intervention effects. RESULTS: Participants randomized to tailored DVD plus PN were four times more likely to complete CRC screening compared to usual care and almost two and a half times more likely than those who were sent the DVD alone. CONCLUSIONS: Combining telephone-based PN with a mailed, tailored DVD increased CRC screening among low-income and minority patients who did not attend their screening colonoscopy appointments and has potential for wide dissemination.
Up to half of people scheduled for a screening colonoscopy do not complete this test. There is a need for interventions to improve knowledge about colorectal cancer (CRC) screening, enhance access to screening by offering alternative test options, foster skills for completing screening, and mitigate barriers. The purpose of this study was to compare the effects of two interventions aimed at increasing CRC screeninga mailed tailored digital video disc (DVD) alone versus the mailed DVD plus telephone-based patient navigation (PN)for patients who had not completed a scheduled screening colonoscopy. We enrolled 371 patients aged 4575 years who had no CRC risk factors other than age, who were scheduled for a screening colonoscopy but did not attend their appointment. Participants were randomized to receive either: (i) a mailed tailored DVD; (ii) the mailed DVD plus phone-based PN; or (iii) usual care. Those who received the tailored DVD plus PN were four times more likely to complete CRC screening with stool test or colonoscopy compared to usual care. Combining telephone-based PN with a mailed, tailored DVD increased CRC screening among low-income and minority patients who did not attend a scheduled screening colonoscopy appointment.

Conducting clinical research in public sector community mental health centers (CMHCs) can be challenging. The purpose of this report is to describe the challenges our research team encountered in engaging CMHC providers in a clinical trial aimed at testing an intervention to improve parent activation and engagement in their child's behavioral healthcare. We discuss the intervention we aimed to test, the challenges we encountered engaging providers, and the barriers to engagement that we identified. The barriers included restrictive inclusion criteria, an ambitious randomized controlled design, a dyadic (provider-parent) recruitment plan, a requirement to record provider-parent sessions, and high day-to-day practice demands on providers. The strategies we used to address the barriers and a discussion of the "trade-offs" these strategies introduced are presented. Improving provider engagement in research in CMHCs can avoid research delays or termination of studies and ultimately mitigate an early blockage in the research-to-practice pipeline.
ABSTRACT
BACKGROUND: Immunotherapy using a checkpoint inhibitor (CPI) alone or in combination with chemotherapy is the standard of care for treatment-naive patients with advanced non-small cell lung cancer (NSCLC) without driver mutations for which targeted therapies have been approved. It is unknown whether continuing CPI treatment beyond disease progression results in improved outcomes. METHODS: Patients who experienced progressive disease (PD) after a clinical benefit from chemotherapy plus a CPI were enrolled. Patients received pembrolizumab (200 mg every 3 weeks) plus next-line chemotherapy. The primary end point was progression-free survival (PFS) according to the Response Evaluation Criteria in Solid Tumors (version 1.1). Key secondary end points included the overall survival (OS), clinical benefit rate, and toxicity. The authors' hypothesis was that continuing pembrolizumab beyond progression would improve the median PFS to 6 months in comparison with a historical control of 3 months with single-agent chemotherapy alone. RESULTS: Between May 2017 and February 2020, 35 patients were enrolled. The patient and disease characteristics were as follows: 51.4% were male; 82.9% were current or former smokers; and 74.3%, 20%, and 5.7% had adenocarcinoma, squamous cell carcinoma, and NSCLC not otherwise specified, respectively. The null hypothesis that the median PFS would be 3 months was rejected (p < .05). The median PFS was 5.1 months (95% confidence interval [CI], 3.6-8.0 months). The median OS was 24.5 months (95% CI, 15.6-30.9 months). The most common treatment-related adverse events were fatigue (60%), anemia (54.3%), and nausea (42.9%). There were no treatment-related deaths. CONCLUSIONS: Pembrolizumab plus next-line chemotherapy in patients with advanced NSCLC who experienced PD after a clinical benefit from a CPI was associated with statistically significant higher PFS in comparison with historical controls of single-agent chemotherapy alone.

BACKGROUND: The impact of pandemic has had worse effects in countries with already stretched healthcare resources. study's The study aimed to explore changes in epilepsy care delivery in resource-limited countries during and since the acute phase of the COVID-19 pandemic. METHOD: A cross-sectional survey was conducted in 22 countries among healthcare providers (HCPs) caring for persons with epilepsy (PWE), in collaboration with newly formed global collaborators, the International Epilepsy Equity Group. Findings were compared based on the World Bank Ranking (WBR) and HCPs' practice type. Data were analyzed using Chi-square tests (α = 0.05) and pairwise multiple comparisons with α = 0.017 (Bonferroni adjustment). Open-ended responses were analyzed using thematic analysis. FINDINGS: A total of 241 HCPs participated in the study. Of these, 8.30%, 65.98%, and 21.99% were from high-income (HIC), upper-middle-income (UMIC), and lower-middle-income countries (LMICs), respectively. Among HCPs, 31.12% were adult specialists, and 43.98% were pediatric specialists. During the acute phase of the pandemic, HCPs reported that the major barrier for PWE was difficulty reaching physicians/healthcare providers. Except for difficulty reaching physicians/healthcare providers (WBR P = 0.01 HIC < LMIC), no other significant differences in barriers during the acute phase were observed. Since the acute phase of the pandemic, the major concern for PWE was fear of getting infected with the SARS-CoV-2 virus. Significant differences in concerns since the acute phase included lockdowns (WBR: P = 0.03 UMIC < LMIC), fiscal difficulties (WBR: P < 0.001 UMICs < LMICs, UMICs < HIC; practice type: P = 0.006 adult < others, pediatrics < others), clinic closure (WBR: P = 0.003 UMIC < HIC; practice type: P =< 0.001 adult < others, pediatric < others), and long waiting times (WBR: P = 0.005, LMIC < UMIC, LMIC < HIC; practice type: P = 0.006 pediatric < adults). Diagnostic services, including EEG, MRI, CT (practice type: P < 0.001, adult < others; pediatric < others), and lab work (WBR: P = 0.01 UMIC < HIC), were restricted. The telephone was the most reported teleconsultation method used. Except for SMS/texting (WBR P = 0.02 UMIC < LMIC), there were no significant differences in teleconsultation methods used. DISCUSSION: There is a high probability that the initial wave and consequent reduction of in-person care, restriction of health services, and fiscal difficulties affecting all involved in care delivery, led to the disruption of epilepsy care. Additional support are needed in resource-limited countries to cope with future pandemics.

BACKGROUND: The high maternal and neonatal mortality rate in sub-Saharan Africa could be reduced by using navigation by means of mobile devices to increase the number of women who choose to give birth in a health center (HC) with a skilled healthcare practitioner. METHODS: A quasi-experimental design was used to test a midwife-delivered navigation by means of mobile phone. A total of 208 women were randomized to two groups (intervention and control). Women in the intervention group received up to three navigation calls from midwives. Women in the control group received usual antenatal education during prenatal visits. Data were collected using semistructured questionnaires. Childbirth location was determined through medical records. RESULTS: Overall, 180 (87%) women gave birth in a HC with a 3% advantage for the intervention group. A total of 86% (88/102) of the control group gave birth in a HC versus 89% (92/103) for the intervention group (Χ2 = 0.44, p-value = 0.51), with an unadjusted odds ratio of 1.33 (95% CI: 0.57, 3.09). Among those with personal phones, 91% (138/152) had a birth in a HC versus 79% (42/53) in those without a personal phone (Χ2 = 4.89, p-value = 0.03). CONCLUSIONS: The results of this study indicate that it is feasible to deliver phone-based navigation to support birth in a HC; personal phone ownership may be a factor in the success of this strategy.
ABSTRACT
BACKGROUND: Home health care (HHC) patients with diabetes are at high risk for inpatient admissions. PURPOSE: To identify variables associated with inpatient admissions among adults age ≥50 with diabetes receiving HHC in the community and in assisted living (AL). METHODS: Retrospective HHC data (collected October 2021 to March 2022 in the Southern United States) from the Outcome and Assessment Information Set D were analyzed with logistic regression (n = 5,308 patients). DISCUSSION: The inpatient admission rate was 29.5%. For community-dwelling patients, multiple hospitalizations, depression, limited cognitive function, decreased activities of daily living (ADL) performance, and unhealed pressure ulcer or injury ≥stage 2 were significantly associated with inpatient admission. For those in AL, multiple prior hospitalizations and decreased ability to perform ADLs were associated with inpatient admission. CONCLUSION: Understanding risk factors for inpatient admissions among patients with diabetes can support the identification of at-risk patients and inform interventions.

PURPOSE: National and international guidelines recommend the use of 1 dose of intravesical chemotherapy immediately following surgery for nonmuscle invasive bladder cancer, which is performed infrequently on a population level. We sought to understand the importance of potential environmental and clinical dimensions involved in the decision to offer this therapy. MATERIALS AND METHODS: Urologists from the Michigan Urological Surgery Improvement Collaborative (MUSIC) rated 8 distinct clinical vignettes involving patients with nonmuscle invasive bladder cancer. A ratings-based conjoint analysis method was used to evaluate the clinical vignette responses. Each vignette included 4 clinical dimensions and 2 environmental dimensions, with each dimension consisting of 2 possible attributes. The relative importance of each attribute was derived from the regression model and ranked in order. RESULTS: A total of 58 urologists answered the clinical vignettes which represents >75% of MUSIC sites. The median age of urologists was 53, most were male, and median years in practice was 20 years post residency. An environmental attribute, having a recovery room protocol for instilling and disposing of the chemotherapy, ranked as the most influential attribute for giving postoperative chemotherapy (utility=8.6). The clinical attribute yielding the strongest preference for giving chemotherapy was tumor grade (utility=4.9). These preferences varied by different subgroups of urologists, particularly regarding the type of practice a urologist was in. CONCLUSIONS: This study demonstrates that urologists have clear preferences for when they offer postoperative immediate chemotherapy. Factors beyond just clinical variables play a role in this decision making process such as the structure of the recovery room.

Apicomplexa is a large monophyletic phylum of unicellular, parasitic organisms. Reptiles are hosts to both haemosporidian (Haemosporida) and hemogregarine (Eucoccidiorida) apicomplexan blood parasites. Within reptiles our understanding of their diversity remains limited, with a paucity of information from Australia, despite a high diversity of squamates (snakes and lizards). We provide a preliminary assessment of haemosporidian and hemogregarine diversity occurring in lizards across northern tropical Australia, building on existing data with results from a microscopy and genetic assessment. We screened total of 233 blood slides using microscopy and detected hemogregarines in 25 geckos, 2 skinks and 1 agamid, while haemosporidians were detected in 13 geckos. DNA sequencing of 28 samples of the hemogregarine 18S rRNA (â¼900 bp) nuclear gene revealed five lineages of Australian lizard hemogregarines within heteroxenous adeleids. We sequenced 10 samples of Haemosporida mtDNA (cytb & coI: â¼1313 bp) and phylogenetic analysis with 30 previously published sequences revealed that the Australian Haemosporida grouped within the Haemoproteidae but were not supported as a monophyletic clade. Our results demonstrate that there is significant undocumented evolutionary diversity in Australian lizard haemosporidian and hemogregarine parasites, with preliminary evidence of significantly higher infection rates in geckos.

PURPOSE: The purpose of the study was to compare the individual and total number of symptoms and explore symptom clusters by hyperglycemia status in colorectal cancer survivors (CRCS) with diabetes (type 2). METHODS: A retrospective cohort study was conducted, whereby symptom data were extracted from clinical notes in electronic health records. CRCS (stage II or III) diagnosed between 2007 and 2017 who had diabetes and at least one HbA1c within 8 months of initial chemotherapy were included. Zero-inflated negative binomial regression analysis was used to examine total symptoms by hyperglycemia status (hyperglycemia versus no hyperglycemia). Exploratory factor analysis was conducted to identify symptom clusters. RESULTS: Two hundred forty-three CRCS met inclusion criteria. CRCS with hyperglycemia (HbA1c ≥ 6.5%) had greater individual symptoms (fatigue and depression) and total number of symptoms than those with no hyperglycemia. Two distinct symptom clusters, with five (nausea, vomiting, constipation, fatigue, and peripheral neuropathy) and two symptoms (anxiety and depression), were identified among CRCS with hyperglycemia. CONCLUSION: These findings indicate that CRCS with diabetes and hyperglycemia had more symptoms and two distinct symptom clusters compared to those with no hyperglycemia. Prospective research studies are needed to examine the role of hyperglycemia in symptoms among CRCS with diabetes. Understanding hyperglycemia's influence is important as it is a modifiable risk factor towards which prevention and intervention can be directed, potentially mitigating symptoms and symptom clusters and improving outcomes for CRCS with diabetes.

PURPOSE: To evaluate the acceptability, satisfaction, and preliminary efficacy of cognitive training for improving cognitive function and health outcomes in breast cancer survivors (BCS). PATIENTS AND METHODS: BCS enrolled in this 2-group randomized, double-masked controlled trial of cognitive training. Primary outcomes included the acceptability and satisfaction of the interventions. Secondary outcomes included examining the effect size and reliable improvement of perceived cognitive function and health outcomes, including work ability, health perception (status and change), and quality of life. Exploratory outcomes were performance on neuropsychological tests and plasma levels of brain-derived neurotropic factor (BDNF). Data were collected at baseline and immediately post-intervention. Using ANCOVA models, the intervention was compared to attention control while adjusting for covariates and baseline values. The effect sizes for differences in means and the reliable improvement percentage were reported. RESULTS: Thirty-six BCS completed the study and were on average 57.6 (SD = 8.0) years old, 59.4% Caucasian, and had some college education (74.5%). Both programs were reported to be satisfactory and acceptable. Non-significant small effect sizes were noted for the intervention on cognitive abilities (d = 0.26) and cognitive concerns (d = - 0.32), with reliable improvement noted in 32% and 28% of BCS, respectively. Small to medium effect sizes were noted in improvement in work ability (d = 0.37) and health perception status (d = 0.30) and change (d = 0.60, p < 0.05). CONCLUSIONS: Cognitive training was acceptable to BCS and resulted in improvement in perceived cognitive function and perceptions of "real-world" health benefits. A larger randomized controlled trial is warranted to determine its effectiveness for objective cognitive performance.

A process evaluation was conducted as part of a comparative effectiveness trial of a mailed interactive educational DVD intervention to promote colorectal cancer screening among average-risk patients who did not attend a scheduled colonoscopy. Participants (n = 371) for the trial were randomized to (1) mailed DVD, (2) mailed DVD plus patient navigation, or (3) usual care. Participants (n = 243) randomized to the two DVD intervention arms were called 2 weeks after mailing materials to complete a process evaluation interview about the DVD (September 2017-February 2020). Forty-nine (20%) participants were not reached, and 194 (80%) participants watched the DVD and completed the interview. The process evaluation assessed whether (1) the DVD content was helpful, (2) any new information was learned by participants, (3) the appropriate amount of information was included in the DVD, (4) participants were engaged when watching the DVD, (5) the DVD content was relevant, (6) participants were satisfied with the DVD (7) participants would recommend the DVD to others, and (8) their opinion about colorectal cancer screening was changed by watching the DVD. Among participants who watched the DVD, 99% reported the screening information was very or somewhat helpful, 47% learned new information, 75% said the DVD included the right amount of information, they were engaged (M = 3.35 out of 4, SD = 0.49), 87% reported all or most information applied to them, they were satisfied (M = 3.42 out of 4, SD = 0.39) with DVD content, 99% would recommend the DVD to others, and 45% reported changing their opinion about screening. To understand the effects of interventions being tested in trials and to plan the dissemination of evidence-based interventions, process evaluation is critical to assess the dose received and acceptability of behavioral interventions.

Background CD-30 is highly expressed in some patients with non-seminomatous germ-cell tumors. Brentuximab vedotin is an antibody-drug conjugate directed to CD-30. We report a phase 2 trial of brentuximab vedotin in patients with chemo-refractory GCT. Patients and methods This is a single arm, two cohort phase 2 trial investigating brentuximab vedotin 1.8 mg/kg IV every 3 weeks until disease progression or intolerable toxicities in patients with relapsed GCT who have no curative options. Patients with mGCT who progressed after first line cisplatin-based chemotherapy and after at least 1 salvage regimen (high-dose or standard-dose chemotherapy) were eligible. CD30 expression was assessed and two cohorts defined: CD30 positive and CD30 negative/unknown. Results 18 patients were enrolled. Median age 34.7 (range, 23-56). All patients had non-seminoma. Median AFP 4.9 (range, 1-219,345) and hCG 282 (range, 0.6-172,064). Five patients had late relapse (> 2 years). Median number of previous chemotherapy regimens was 3 (range, 2-7). Ten patients received prior high-dose chemotherapy. Seven patients had positive CD30 staining. There were two grade 3 treatment-related adverse events. No partial or complete responses were observed. 6 patients achieved radiographic stable disease (range, 9-14.9 weeks), 5 had elevated AFP or hCG at trial entry and all 5 had transient > 50% decline in baseline AFP/hCG: 4 had CD30 -ve and 2 had CD30 + ve staining; 10 patients had progression of disease as their best response; 2 were not evaluable for response. Conclusion Brentuximab vedotin does not appear to have clinically meaningful single-agent activity in patients with refractory GCT.

INTRODUCTION: Although African Americans have the highest colorectal cancer (CRC) incidence and mortality rates of any racial group, their screening rates remain low. STUDY DESIGN/PURPOSE: This randomized controlled trial compared efficacy of two clinic-based interventions for increasing CRC screening among African American primary care patients. METHODS: African American patients from 11 clinics who were not current with CRC screening were randomized to receive a computer-tailored intervention (n = 335) or a non-tailored brochure (n = 358) designed to promote adherence to CRC screening. Interventions were delivered in clinic immediately prior to a provider visit. Univariate and multivariable logistic regression models analyzed predictors of screening test completion. Moderators and mediators were determined using multivariable linear and logistic regression analyses. RESULTS: Significant effects of the computer-tailored intervention were observed for completion of a stool blood test (SBT) and completion of any CRC screening test (SBT or colonoscopy). The colonoscopy screening rate was higher among those receiving the computer-tailored intervention group compared to the nontailored brochure but the difference was not significant. Predictors of SBT completion were: receipt of the computer-tailored intervention; being seen at a Veterans Affairs Medical Center clinic; baseline stage of adoption; and reason for visit. Mediators of intervention effects were changes in perceived SBT barriers, changes in perceived colonoscopy benefits, changes in CRC knowledge, and patient-provider discussion. Moderators of intervention effects were age, employment, and family/friend recommendation of screening. CONCLUSION: This one-time computer-tailored intervention significantly improved CRC screening rates among low-income African American patients. This finding was largely driven by increasing SBT but the impact of the intervention on colonoscopy screening was strong. Implementation of a CRC screening quality improvement program in the VA site that included provision of stool blood test kits and follow-up likely contributed to the strong intervention effect observed at that site. The trial is registered at ClinicalTrials.gov as NCT00672828.

Early detection of lung cancer offers an important opportunity to decrease mortality while it is still treatable and curable. Thirteen secretory proteins that are Stat3 downstream gene products were identified as a panel of biomarkers for lung cancer detection in human sera. This panel of biomarkers potentially differentiates different types of lung cancer for classification. Among them, the transthyretin (TTR) concentration was highly increased in human serum of lung cancer patients. TTR concentration was also induced in the serum, bronchoalveolar lavage fluid, alveolar type II epithelial cells, and alveolar myeloid cells of the CCSP-rtTA/(tetO)7-Stat3C lung tumor mouse model. Recombinant TTR stimulated lung tumor cell proliferation and growth, which were mediated by activation of mitogenic and oncogenic molecules. TTR possesses cytokine functions to stimulate myeloid cell differentiation, which are known to play roles in tumor environment. Further analyses showed that TTR treatment enhanced the reactive oxygen species production in myeloid cells and enabled them to become functional myeloid-derived suppressive cells. TTR demonstrated a great influence on a wide spectrum of endothelial cell functions to control tumor and immune cell migration and infiltration. TTR-treated endothelial cells suppressed T cell proliferation. Taken together, these 13 Stat3 downstream inducible secretory protein biomarkers potentially can be used for lung cancer diagnosis, classification, and as clinical targets for lung cancer personalized treatment if their expression levels are increased in a given lung cancer patient in the blood.

OBJECTIVE: In participants with traumatic brain injury (TBI) and peer controls, examine (1) differences in negative attributions (interpret ambiguous behaviors negatively); (2) cognitive and emotional factors associated with negative attributions; and (3) negative attribution associations with anger responses, life satisfaction, and participation. SETTING: Two TBI outpatient rehabilitation centers. PARTICIPANTS: Participants with complicated mild to severe TBI (n = 105) and peer controls (n = 105). DESIGN: Cross-sectional survey study. MAIN MEASURES: Hypothetical scenarios describing ambiguous behaviors were used to assess situational anger and attributions of intent, hostility, and blame. Executive functioning, perspective taking, emotion perception and social inference, alexithymia, aggression, anxiety, depression, participation, and life satisfaction were also assessed. RESULTS: Compared with peer controls, participants with TBI rated behaviors significantly more intentional, hostile, and blameworthy. Regression models explained a significant amount of attribution variance (25%-43%). Aggression was a significant predictor in all models; social inference was also a significant predictor of intent and hostility attributions. Negative attributions were associated with anger responses and lower life satisfaction. CONCLUSION: People with TBI who have higher trait aggression and poor social inferencing skills may be prone to negative interpretations of people's ambiguous actions. Negative attributions and social inferencing skills should be considered when treating anger problems after TBI.

Cancer incidence and mortality are increasing in low- and middle-income countries (LMICs), where more than 75% of global cancer burden will occur by the year 2040. The primary drivers of cancer morbidity and mortality in LMICs are environmental and behavioral risk factors, inadequate prevention and early detection services, presence of comorbidities, and poor access to treatment and palliation. These same drivers also contribute to marked cancer health disparities in high-income countries. Studying cancer in LMICs provides opportunities to better understand and address these drivers to benefit populations worldwide, and reflecting this, global oncology as an academic discipline has grown substantially in recent years. However, sustaining this growth requires a uniquely trained workforce with the skills to pursue relevant, rigorous, and equitable global oncology research. Despite this need, dedicated global cancer research training programs remain somewhat nascent and uncoordinated. In this paper, we discuss efforts to address these gaps in global cancer research training at the US National Institutes of Health.

BACKGROUND: Associations among illness perceptions of viruses, anxiety and depression symptoms, and self-management decisions, such as mask-wearing, are critical to informing public health practices to mitigate the short- and long-term consequences of the SARS-CoV-2 viral pandemic. PURPOSE: Guided by the common-sense model of self-regulation, this observational study examined associations among illness perceptions of COVID-19, anxiety, and depression symptoms among community-dwelling adults. METHOD: Data were collected from 1380 adults living in the United States early in the pandemic (03-23-2020 to 06-02-2020). Participants completed online surveys. Analyses were conducted using descriptive statistics and correlations. FINDINGS: While increased anxiety symptoms were associated with less perceived personal control, greater concern, and higher emotional responsiveness, increased depression symptoms were related to lower concern as well as greater emotional responsiveness and perceived consequences of the pandemic. DISCUSSION: Associations among illness perceptions, anxiety, and depression symptoms may impact viral spread mitigation behavior adoption.

OBJECTIVES: (1) To explore the construct validity of the Ambiguous Intentions Hostility Questionnaire (AIHQ) in participants with traumatic brain injury (TBI) (ie, confirm negative attributions are associated with anger and aggression); and (2) use the AIHQ to examine negative attribution differences between participants with and without TBI. SETTING: Two rehabilitation hospitals. PARTICIPANTS: Eighty-five adults with TBI and 86 healthy controls (HCs). DESIGN: Cross-sectional survey. MAIN MEASURES: The AIHQ, a measure of negative attributions (intent, hostility, and blame), anger, and aggressive responses to hypothetical scenarios. RESULTS: Attributions were significantly correlated with anticipated anger and aggressive responses to AIHQ scenarios. Compared with HCs, participants with TBI reported stronger negative attributions (P ≤ .001), anger (P = .021), and aggressive responses (P = .002) to the scenarios. CONCLUSION: Negative attributions were associated with anger and aggression responses, demonstrating construct validity of the AIHQ in the TBI population. Participants with TBI judged others' behaviors more severely than HCs, similar to prior research using a different attribution measure. The AIHQ has promise as a practical instrument for assessing negative attributions after TBI.

BACKGROUND AND AIMS: Locally advanced pancreatic cancer (LAPC) has a poor prognosis. There are limited data describing the use of photodynamic therapy (PDT) for pancreatic cancer in humans. We hypothesized that EUS-guided PDT for LAPC is safe, technically feasible, and produces a dose- and time-dependent increasing degree of image-defined tumor necrosis. METHODS: In a single-center, prospective, dose-escalation phase 1 study, patients with treatment-naïve LAPC received intravenous porfimer sodium (Concordia Laboratories Inc, St Michael, Barbados) followed 2 days later by EUS-PDT. EUS-PDT was performed by puncture with a 19-gauge needle and insertion of a 1.0-cm light diffuser (Pioneer Optics, Bloomfield, Conn) and illumination with a 630-nm light (Diomed Inc, Andover, Mass). A CT scan 18 days after PDT was done to assess for change in pancreatic necrosis. Nab-paclitaxel (125 mg/ m2 intravenously) and gemcitabine (1000 mg /m2 intravenously) were initiated 7 days after CT and given weekly for 3 of 4 weeks (1 cycle) until disease progression or unacceptable toxicity. RESULTS: Twelve patients (mean age, 67 ± 6 years; 8 male) with tumors (mean diameter, 45.2 ± 12.9 mm) in the head and/or neck (8) or body and/or tail (4) underwent EUS-PDT. Compared with baseline imaging, increased volume and percentage of tumor necrosis were observed in 6 of 12 patients (50%) after EUS-PDT. The mean overall increases in volume and percentage necrosis were 10 ± 26 cm3 (P = .20) and 18% ± 22% (P = .016), respectively. After a median follow-up of 10.5 months (range, 1.0-37.4 months), median progression-free (PFS) and overall survival (OS) were 2.6 months (95% confidence interval, 0.7, not estimable) and 11.5 months (95% confidence interval, 1.1, 16.9), respectively. Surgical resection was attempted in 2 patients, and pathology showed a complete response (n = 1) and residual 2-mm tumor (n = 1). There were 8 serious adverse events and none related to EUS or EUS-PDT. CONCLUSION: EUS-PDT for LAPC appears to be safe and produces measurable imaged-defined tumor necrosis. Phase 2 studies are warranted. (Clinical trial registration number: NCT01770132.).

Co-infections with multiple parasite taxa are ubiquitous in nature and have the potential to impact the co-evolutionary dynamics between host and parasite, though patterns of phylogenetic community structure of co-infecting parasites and the processes that generate these patterns have rarely been studied across diverse host-parasite communities. Here, we tested for the roles of host and parasite evolutionary history as well as environmental variables as drivers of phylogenetic community structure among co-infecting haemosporidian (malaria) parasites and their avian hosts in the North American boreal forest, a region characterized by an extraordinarily high blood parasite co-infection rate. We used multiple methods to identify non-random patterns of co-infection among parasite species and determined whether these patterns were influenced more by co-evolutionary host associations or environmental variables. We used model-based approaches to test whether parasites that occurred together in a single host individual exhibited phylogenetic clustering or overdispersion. Lastly, we tested whether the observed phylogenetic community structure could be explained by parasites having convergently evolved similar patterns of host associations. We found that haemosporidian parasite co-infections occurred at a high frequency in the boreal forest system and that parasite taxa co-occurred in significantly non-random patterns within host individuals and among host species. Parasite taxa that occurred in co-infections tended to be phylogenetically overdispersed. We show that this pattern of phylogenetic overdispersion can be attributed largely to the effect of evolutionarily labile, convergent host associations that have resulted in the pool of parasites that have the potential to infect a given host consisting nearly exclusively of distantly related lineages. Our findings illustrate that environmental filtering of convergent traits can produce phylogenetically overdispersed communities, even at the level of co-infecting parasites within an individual host organism. Broadly, this analysis illustrates how co-evolutionary history can have a strong influence on the modern phylogenetic community assembly of diverse host-symbiont communities.
