Sleep as a mediator of the relationship between social class and health in higher education students

A substantial body of research indicates that higher education students from lower social class backgrounds tend to have poorer health than those from higher social class backgrounds. To investigate sleep as a potential mediator of this relationship, online survey responses of students from five large Australian universities, one Irish university and one large Australian technical college were analysed in three studies (Study 1 N = 628; Study 2 N = 376; Study 3 N = 446). The results revealed that sleep quality, sleep duration, sleep disturbances, pre-sleep worries and sleep schedule variability mediated the relationship between social class and physical and mental health. Sleep remained a significant mediator when controlling for related variables and other mediators. Thus, the findings suggest that sleep partly explains social class differences in health. We discuss the importance of addressing sleep issues among students from lower social class backgrounds.

Content appraisal and age moderate the relationship between passive social media use and mental ill-being

An important distinction to make when assessing the impact of social media use on mental health is whether the use is passive (e.g., browsing) or active (e.g., posting). Recent research suggests that the connection between passive social media use and mental ill-being is inconsistent, with some research finding a significant negative association, while other research finds no such association. In the present research, we sought to investigate this relationship, as well as two potential moderators of this relationship: the subjective appraisal of social media content social media users consume (i.e., positively or negatively-appraised) and age of users. In a cross-sectional survey of Australian and United States Facebook users (N = 991), there was no direct relationship between passive use and mental ill-being, however user age and positive (but not negative) content appraisal were found to moderate the relationship between passive use and mental ill-being. Specifically, the relationship between passive use and mental ill-being became weaker as subjective positive appraisal increased, and it reversed to become negative at high levels of positive appraisal. Additionally, the positive relationship between passive use and mental ill-being became weaker as age of social media users increased, and the direction of this relationship became negative at the oldest ages of social media users. These results suggest that the relationship between social media use and mental ill-being is more nuanced than previous research suggests. In particular, higher amounts of passive Facebook use may have a less negative, or even a positive effect on social media users' mental health when the content being (passively) consumed is positively appraised, or when users are older.

Intersectional Person Perception: A Scoping Review of Studies Investigating the Roles of Category Relationships and Cognitive Processes

This review considered experimental studies that used an intersectional framework in order to examine (1) how perceived relationship between the categories in a given intersection impacts the perception of its members and (2) how intersectional person perception has been studied through different cognitive processes. A systematic search in databases identified 5,393 records, and a screening processes resulted in 43 articles reporting 110 studies. The way intersectional targets were cognitively processed depended on contextual factors as well as on the perceived relationship between intersected identities (e.g., perceived [in-]congruence between identities). Less prototypical intersectional targets (e.g., Black gay men) sometimes experienced intersectional invisibility, facing both relative advantages (e.g., being less associated with certain negative stereotypes), and disadvantages (e.g., being overlooked, less recognized) compared to more prototypical members of their constituent ingroups (e.g., Black people, gay men). Future work should incorporate observed exceptions to these patterns and expand the cultural context of analysis.

Covariate-specific evaluation of continuous biomarker

Diagnostic tests usually need to operate at a high sensitivity or specificity level in practice. Accordingly, specificity at the controlled sensitivity, or vice versa, is a clinically sensible performance metric for evaluating continuous biomarkers. Meanwhile, the performance of a biomarker may vary across sub-populations as defined by covariates, and covariate-specific evaluation can be informative. In this article, we develop a novel modeling and estimation method for covariate-specific specificity at a controlled sensitivity level. Unlike existing methods which typically adopt elaborate models of covariate effects over the entire biomarker distribution, our approach models covariate effects locally at a specific sensitivity level of interest. We also extend our proposed model to handle the whole continuum of sensitivities via dynamic regression and derive covariate-specific ROC curves. We provide the variance estimation through bootstrapping. The asymptotic properties are established. We conduct extensive simulation studies to evaluate the performance of our proposed methods in comparison with existing methods, and further illustrate the applications in two clinical studies for aggressive prostate cancer.

Evaluation of daily environmental cleaning and disinfection practices in veterans affairs acute and long-term care facilities: A mixed methods study

OBJECTIVES

To describe daily environmental cleaning and disinfection practices and their associations with cleaning rates while exploring contextual factors experienced by healthcare workers involved in the cleaning process.

METHODS

A convergent mixed methods approach using quantitative observations (ie, direct observation of environmental service staff performing environmental cleaning using a standardized observation form) and qualitative interviews (ie, semistructured interviews of key healthcare workers) across 3 Veterans Affairs acute and long-term care facilities.

RESULTS

Between December 2018 and May 2019 a total of sixty-two room observations (N = 3602 surfaces) were conducted. The average observed surface cleaning rate during daily cleaning in patient rooms was 33.6% for all environmental surfaces and 60.0% for high-touch surfaces (HTS). Higher cleaning rates were observed with bathroom surfaces (Odds Ratio OR = 3.23), HTSs (OR = 1.57), and reusable medical equipment (RME) (OR = 1.40). Lower cleaning rates were observed when cleaning semiprivate rooms (OR = 0.71) and rooms in AC (OR = 0.56). In analysis stratified by patient presence (ie, present, or absent) in the room during cleaning, patient absence was associated with higher cleaning rates for HTSs (OR = 1.71). In addition, the odds that bathroom surfaces being cleaned more frequently than bedroom surfaces decreased (OR = 1.97) as well as the odds that private rooms being cleaned more frequently than semi-private rooms also decreased (OR = 0.26; 0.07-0.93). Between January and June 2019 eighteen qualitative interviews were conducted and found key themes (ie, patient presence and semiprivate rooms) as potential barriers to cleaning; this supports findings from the quantitative analysis.

CONCLUSION

Overall observed rates of daily cleaning of environmental surfaces in both acute and long-term care was low. Standardized environmental cleaning practices to address known barriers, specifically cleaning practices when patients are present in rooms and semi-private rooms are needed to achieve improvements in cleaning rates.

Further evidence that system justification amongst the disadvantaged is positively related to superordinate group identification

Members of disadvantaged groups sometimes support societal systems that enable the very inequalities that disadvantaged them. Is it possible to explain this puzzling system-justifying orientation in terms of rational group-interested motives, without recourse to a separate system motive? The social identity model of system attitudes (SIMSA) claims that it is. SIMSA proposes that the system justification shown by a disadvantaged group (e.g., African American women) can sometimes support identity needs that are tied to a more inclusive (superordinate) in-group (e.g., Americans). There is already some supportive evidence for this proposition, but it is not yet clear whether: (1) such trends are visible in a wider range of disadvantaged contexts, and (2) this explanation also applies to those who are strongly invested in their subgroup (e.g., feminists). In two waves of a large nationally representative survey from 21 to 23 European states (N_total = 84,572) and two controlled experiments (N_total = 290 women), we found that: (a) system justification was positively associated with superordinate ingroup identification across multiple cases of disadvantage (Studies 1-3), (b) system justification increased when this inclusive identity was made more salient (Studies 2 & 3), and (c) system justification was visible even amongst feminists when they activated their superordinate (Italian) identity (Study 3).

An exploratory investigation of the reliability and validity of the Independent-Interdependent Problem-Solving Style Scale

The Independent-Interdependent Problem-Solving Scale is based on Cross et al.'s conceptualisation of relational-interdependent self-construal. The IIPSS provides a relatively context-free measure of people's tendencies to solve problems independently or with the help of others. Because previous investigations have not provided extensive evidence for the reliability and validity of the IIPSS, the current research aimed to test the psychometric properties of this novel measure. Investigations of four student samples (combined N = 1157) and one sample comprised of academic researchers (N = 198) generally supported the reliability and validity of the IIPSS. Exploratory factor analysis of IIPSS items yielded a single factor structure. However, confirmatory factor analyses did not demonstrate good model fit for the one factor solution and instead yielded good model fit for two underlying factors. The IIPSS showed adequate test-retest reliability and predicted positive associations with social personality traits. It also showed no significant associations with measures of demand characteristics and social desirability. Future research needs to be undertaken to further assess the factor structure and address shortcomings of the present research such as utilising objective data in addition to self-reports to assess the scale's validity.

Aberrant hyperexpression of the RNA binding protein FMRP in tumors mediates immune evasion

Many human cancers manifest the capability to circumvent attack by the adaptive immune system. In this work, we identified a component of immune evasion that involves frequent up-regulation of fragile X mental retardation protein (FMRP) in solid tumors. FMRP represses immune attack, as revealed by cancer cells engineered to lack its expression. FMRP-deficient tumors were infiltrated by activated T cells that impaired tumor growth and enhanced survival in mice. Mechanistically, FMRP’s immunosuppression was multifactorial, involving repression of the chemoattractant C-C motif chemokine ligand 7 (CCL7) concomitant with up-regulation of three immunomodulators—interleukin-33 (IL-33), tumor-secreted protein S (PROS1), and extracellular vesicles. Gene signatures associate FMRP’s cancer network with poor prognosis and response to therapy in cancer patients. Collectively, FMRP is implicated as a regulator that orchestrates a multifaceted barrier to antitumor immune responses.

What Experts Think About Prostate Cancer Management During the COVID-19 Pandemic: Report from the Advanced Prostate Cancer Consensus Conference 2021

Patients with advanced prostate cancer (APC) may be at greater risk for severe illness, hospitalisation, or death from coronavirus disease 2019 (COVID-19) due to male gender, older age, potential immunosuppressive treatments, or comorbidities. Thus, the optimal management of APC patients during the COVID-19 pandemic is complex. In October 2021, during the Advanced Prostate Cancer Consensus Conference (APCCC) 2021, the 73 voting members of the panel members discussed and voted on 13 questions on this topic that could help clinicians make treatment choices during the pandemic. There was a consensus for full COVID-19 vaccination and booster injection in APC patients. Furthermore, the voting results indicate that the expert's treatment recommendations are influenced by the vaccination status: the COVID-19 pandemic altered management of APC patients for 70% of the panellists before the vaccination was available but only for 25% of panellists for fully vaccinated patients. Most experts (71%) were less likely to use docetaxel and abiraterone in unvaccinated patients with metastatic hormone-sensitive prostate cancer. For fully vaccinated patients with high-risk localised prostate cancer, there was a consensus (77%) to follow the usual treatment schedule, whereas in unvaccinated patients, 55% of the panel members voted for deferring radiation therapy. Finally, there was a strong consensus for the use of telemedicine for monitoring APC patients. PATIENT SUMMARY: In the Advanced Prostate Cancer Consensus Conference 2021, the panellists reached a consensus regarding the recommendation of the COVID-19 vaccine in prostate cancer patients and use of telemedicine for monitoring these patients.

Management of Patients with Advanced Prostate Cancer: Report from the Advanced Prostate Cancer Consensus Conference 2021

BACKGROUND

Innovations in treatments, imaging, and molecular characterisation in advanced prostate cancer have improved outcomes, but various areas of management still lack high-level evidence to inform clinical practice. The 2021 Advanced Prostate Cancer Consensus Conference (APCCC) addressed some of these questions to supplement guidelines that are based on level 1 evidence.

OBJECTIVE

To present the voting results from APCCC 2021.

DESIGN, SETTING, AND PARTICIPANTS

The experts identified three major areas of controversy related to management of advanced prostate cancer: newly diagnosed metastatic hormone-sensitive prostate cancer (mHSPC), the use of prostate-specific membrane antigen ligands in diagnostics and therapy, and molecular characterisation of tissue and blood. A panel of 86 international prostate cancer experts developed the programme and the consensus questions.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The panel voted publicly but anonymously on 107 pre-defined questions, which were developed by both voting and non-voting panel members prior to the conference following a modified Delphi process.

RESULTS AND LIMITATIONS

The voting reflected the opinions of panellists and did not incorporate a standard literature review or formal meta-analysis. The answer options for the consensus questions received varying degrees of support from panellists, as reflected in this article and the detailed voting results reported in the Supplementary material.

CONCLUSIONS

These voting results from a panel of experts in advanced prostate cancer can help clinicians and patients to navigate controversial areas of management for which high-level evidence is scant. However, diagnostic and treatment decisions should always be individualised according to patient characteristics, such as the extent and location of disease, prior treatment(s), comorbidities, patient preferences, and treatment recommendations, and should also incorporate current and emerging clinical evidence and logistic and economic constraints. Enrolment in clinical trials should be strongly encouraged. Importantly, APCCC 2021 once again identified salient questions that merit evaluation in specifically designed trials.

PATIENT SUMMARY

The Advanced Prostate Cancer Consensus Conference is a forum for discussing current diagnosis and treatment options for patients with advanced prostate cancer. An expert panel votes on predefined questions focused on the most clinically relevant areas for treatment of advanced prostate cancer for which there are gaps in knowledge. The voting results provide a practical guide to help clinicians in discussing treatment options with patients as part of shared decision-making.

Identification and characterization of a new ensemble of cometary organic molecules

In-situ study of comet 1P/Halley during its 1986 apparition revealed a surprising abundance of organic coma species. It remained unclear, whether or not these species originated from polymeric matter. Now, high-resolution mass-spectrometric data collected at comet 67P/Churyumov-Gerasimenko by ESA’s Rosetta mission unveil the chemical structure of complex cometary organics. Here, we identify an ensemble of individual molecules with masses up to 140 Da while demonstrating inconsistency of the data with relevant amounts of polymeric matter. The ensemble has an average composition of C₁H_1.56O_0.134N_0.046S_0.017, identical to meteoritic soluble organic matter, and includes a plethora of chain-based, cyclic, and aromatic hydrocarbons at an approximate ratio of 6:3:1. Its compositional and structural properties, except for the H/C ratio, resemble those of other Solar System reservoirs of organics—from organic material in the Saturnian ring rain to meteoritic soluble and insoluble organic matter –, which is compatible with a shared prestellar history.

A new analysis of Rosetta mass spectra reveals an ensemble of complex organic molecules with striking similarities to other organic reservoirs in the Solar System, including Saturn’s ring rain material, pointing at a likely joint prestellar history.

Brexit and Trump: Which Theory of Social Stasis and Social Change Copes Best With the New Populism?

Why do voters seek to change the political landscape or to retain it? System justification theory (SJT) proposes that a separate system motive to preserve the existing order drives support for the status-quo, and that this motivation operates independently from personal and collective interests. But how does this explanation apply to recent populist shifts in the political order such as Brexit and the emergence of Donald Trump? While the system motive may seem useful in understanding why the usual progressives (Remain/Clinton voters) may want to stick with an established order, it seems insufficient to explain why the more conservative voters (Brexit/Trump voters) would want to upend the establishment. Thus, we compared SJT’s system motive explanation for the system attitudes of voters on both sides of the political divide to an alternative explanation drawn from the newer social identity model of system attitudes (SIMSA). According to SIMSA, the difficulty in explaining the system attitudes of Brexit/Trump and Remain/Clinton voters from SJT’s system motive standpoint can be resolved by focusing instead on the collective interests that both camps seek to satisfy with their votes. We examined these explanations in two studies conducted soon after Brexit (N = 313) and Trump’s election (N = 289) in 2016, with results providing more support for SIMSA than for SJT.

Yield of ASPECTS and collateral CTA Selection for mechanical thrombectomy within 6-24 hours from symptom onset in a hub and spoke system

BACKGROUND

Recent extended window trials support the benefit of mechanical thrombectomy in anterior circulation large vessel occlusions with clinical-radiographic dissociation. Using trial imaging criteria, 6% were found eligible for MT in the EW in a hub-and-spoke system. We examined the eligibility and outcomes in consecutive extended window-mechanical thrombectomy patients using more pragmatic selection criteria.

METHODS

We retrospectively analyzed single-institution data of anterior circulation large vessel occlusions patients presenting between 6-24 h who underwent mechanical thrombectomy based on a priori determined criteria including non-contrast CT head ASPECTS ≥ 6 and/or CTA collateral scores ASITN/SIR 2-4. Primary outcomes consisted of post-mechanical thrombectomy TICI 2b-3 and 3-month modified Rankin scores; safety outcomes consisted of in-hospital mortality and symptomatic intracerebral hemorrhage.

RESULTS

767 consecutive acute ischemic strokes patients presented within the 6-24 hour window, and of these 48 (6%) anterior circulation large vessel occlusions patients underwent mechanical thrombectomy. In this cohort the mean age was 63±17 years, 56% were male, the median NIHSS was 16 [IQR 10-19], the median ASPECTS was 9 (IQR 8-10), and 79% (n=38) had good CTA collaterals. Occlusions were primarily M1 MCA (46%), with 29% tandem occlusions. Successful recanalization (mTICI 2b or 3) was achieved in 73% (n=35), while 6% (n=3) of patients developed symptomatic intracerebral hemorrhage. In-hospital mortality was 25% (n=12) while 40% (n=19) achieved 3-month modified Rankin Scores 0-2.

CONCLUSIONS

Our data suggest the use of pragmatic imaging approach of ASPECTS ≥6 with CTA collateral grade in extended time window which is already established in most hospitals.

Abstract 5708: The DNA methylation landscape of prostate cancer brain metastases

Introduction: Improved survival in prostate cancer through more effective therapies has also led to an increase in the diagnosis of metastases to infrequent locations such as the brain. In the largest cohort of prostate cancer brain metastases (PCBM) yet studied, we investigated the DNA methylation landscape of PCBM.

Methods: Using Illumina EPIC arrays, we profiled the DNA methylation landscapes of 95 metastatic samples from 42 patients, with multi-regional analysis of the metastases from 31 patients. We compared DNA methylation profiles from metastases to the primary prostate cancer (PCa) samples of 18 of these patients. Multi-regional data was obtained for 15 of these. We performed unsupervised analyses of DNA methylation profiles across sample types, and identified differentially methylated CpG sites and regions (DMRs) between PCBM and PCa samples, and PCBM/PCa samples and normal prostate tissue. We integrated our data with targeted-RNA sequencing and whole exome sequencing (WES).

Results: We highlight the epigenetic heterogeneity present in different regions of the PCBM from patients for which multi-regional data were available. While substantial DNA methylation changes were detected in PCa compared to normal prostate tissue, epigenetic dysregulation was strikingly more pronounced in PCBM samples. DNA methylation changes in PCBM involved striking hypermethylation particularly enriched at CpG islands, and associated with activity of the PRC2 complex. We observed a marked distinction of the methylation profiles of SPOP mutant and TMPRSS2-ERG samples. SPOP mutant samples acquired substantially more epigenetic aberrations, particularly enriched at CpG islands which were hypermethylated genome-wide compared to TMPRSS2-ERG PCBM samples, as well as SPOP mutant PCa samples. These changes were strongly associated with the activity of EZH2 and MYC, both of which were overexpressed specifically in SPOP mutant PCBM. TMPRSS2-ERG samples showed fewer DNA methylation changes, but those detected were associated with targets of the SP1 transcription factor.

Conclusion: We show that epigenetic heterogeneity is present in different regions of PCBM. While the distinct methylation landscapes of SPOP mutant and TMPRSS2-ERG PCa has been previously reported, we show that metastasis-specific DNA methylation changes emerge in each of these settings. These observations suggest that the acquisition of DNA methylation changes may be an important feature of PCBM, and may help to improve our understanding of the processes driving the occurrence of these rare metastases.

Lack of consensus identifies important areas for future clinical research: Advanced Prostate Cancer Consensus Conference (APCCC) 2019 findings

BACKGROUND

Innovations in treatments, imaging and molecular characterisation have improved outcomes for people with advanced prostate cancer; however, many aspects of clinical management are devoid of high-level evidence. At the Advanced Prostate Cancer Consensus Conference (APCCC) 2019, many of these topics were addressed, and consensus was not always reached. The results from clinical trials will most reliably plus the gaps.

METHODS

An invited panel of 57 experts voted on 123 multiple-choice questions on clinical management at APCCC 2019. No consensus was reached on 88 (71.5%) questions defined as <75% of panellists voting for the same answer option. We reviewed clinicaltrials.gov to identify relevant ongoing phase III trials in these areas of non-consensus.

RESULTS

A number of ongoing phase III trials were identified that are relevant to these non-consensus issues. However, many non-consensus issues appear not to be addressed by current clinical trials. Of note, no phase III but only phase II trials were identified, investigating side effects of hormonal treatments and their management.

CONCLUSIONS

Lack of consensus almost invariably indicates gaps in existing evidence. The high percentage of questions lacking consensus at APCCC 2019 highlights the complexity of advanced prostate cancer care and the need for robust, clinically relevant trials that can fill current gaps with high-level evidence. Our review of these areas of non-consensus and ongoing trials provides a useful summary, indicating areas in which future consensus may soon be reached. This review may facilitate academic investigators to identify and prioritise topics for future research.

Following the best of us to help them: Group member prototypicality and collective action

While considering the role of group-level factors as predictors of collective action, research has overlooked the role of group prototypes in determining willingness to engage in collective action. To begin to investigate this area, we conducted two correlational studies ( Ns = 141 and 98) in high schools examining the association between prototypical ingroup members’ desire to engage in collective action and participants’ collective action on behalf of a disadvantaged group (immigrants). Results showed a positive association between these two variables. We also investigated boundaries of this effect, finding that the association emerged when participants lacked personal experiences with the disadvantaged group (cross-group friendships; Study 1) or identified more with their ingroup, an effect also found when including a behavioral measure of collective action (Study 2). Intentions to follow the prototypical ingroup member emerged as the mediator (Study 2). It is worth noting that our methodology allowed us to assess prototypicality in a naturalistic context by calculating a metacontrast ratio for each group member, in line with self-categorization theory’s conceptualization of prototypicality. We discuss the theoretical and practical implications, with reference to the role of prototypicality as a means of social influence and to developing social norms in the context of collective action.

Measuring Disability in Consumers of mental health services - psychometric properties of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) in Ghana

The World Health Disability Assessment Scale (WHODAS-2.0) has widely been accepted as the standard measure of disability. However, psychometric testing is mostly performed in developed countries. This paper aims to assess the psychometric properties (reliability, validity) of the WHODAS-2.0 among consumers of mental health services in Ghana. Two translators (expert in English language and Akan language) performed forward and backward translation of the WHODAS-2.0 from English language to Ghanaian language (Twi). A total of 510 consumers of mental health services were recruited consecutively to complete the WHODAS-2.0 using RedCAP. Confirmatory factor analysis was used to analyse the data. All domains in the 6-factor solutions had excellent internal consistency (ω = 0.90-0.98), sufficient convergent validity and had satisfactory discriminant validity except for domain on participation. The CFA model confirmed that the data had a good model fit, CFI = 0.97, TLI = 0.96, RMESA = 0.05, RMR = 0.03; NFI = 0.94; χ²  = 1243.8, df = 529, P < 0.001. Although the WHODAS 2.0 had satisfactory psychometric properties and was thus considered to be a reliable and valid measure for assessing disability and level of functioning in consumers of mental health services, researchers and clinicians should re-consider items within the participation domain. Also, practitioners are encouraged to integrate the WHODAS-2.0 into the collection of data on clinical outcomes, as well as, collecting data on government social protection intervention programmes for consumers.

Molecular medicine tumor board: whole-genome sequencing to inform on personalized medicine for a man with advanced prostate cancer

PURPOSE

Molecular profiling of cancer is increasingly common as part of routine care in oncology, and germline and somatic profiling may provide insights and actionable targets for men with metastatic prostate cancer. However, all reported cases are of deidentified individuals without full medical and genomic data available in the public domain.

PATIENT AND METHODS

We present a case of whole-genome tumor and germline sequencing in a patient with advanced prostate cancer, who has agreed to make his genomic and clinical data publicly available.

RESULTS

We describe an 84-year-old Caucasian male with a Gleason 10 oligometastastic hormone-sensitive prostate cancer. Whole-genome sequencing provided insights into his tumor's underlying mutational processes and the development of an SPOP mutation. It also revealed an androgen-receptor dependency of his cancer which was reflected in his durable response to radiation and hormonal therapy. Potentially actionable genomic lesions in the tumor were identified through a personalized medicine approach for potential future therapy, but at the moment, he remains in remission, illustrating the hormonal sensitivity of his SPOP-driven prostate cancer. We also placed this patient in the context of a large prostate-cancer cohort from the PCAWG (Pan-cancer Analysis of Whole Genomes) group. In this comparison, the patient's cancer appears typical in terms of the number and type of somatic mutations, but it has a somewhat larger contribution from the mutational process associated with aging.

CONCLUSION

We combined the expertise of medical oncology and genomics approaches to develop a molecular tumor board to integrate the care and study of this patient, who continues to have an outstanding response to his combined modality treatment. This identifiable case potentially helps overcome barriers to clinical and genomic data sharing.

Abstract 1434: Uncovering the mechanism of adaptive resistance to RET inhibitors in RET rearranged thyroid cancer

Kinase inhibitors are a critical tool for cancer treatment, but their efficacy is limited by resistance mechanisms. In thyroid and lung cancer RET gene rearrangements result in constitutive MAPK pathway activation and drive malignancy. While treatment with new selective RET inhibitors has been associated with significant clinical responses, a majority of patients experience a partial response or disease stabilization as their best clinical outcome. Resistance to RET inhibitors has emerged as a clinical problem requiring new treatment strategies. Using a combination of drug screening, proteomic, and biochemical profiling we identified a strategy to overcome adaptive resistance to RET inhibitors in human thyroid cancer cell lines and vertebrate animal models. The identification of alternative signaling pathways that reactivates ERK signaling as a mechanism of resistance to RET inhibitors provides an opportunity to anticipate resistance to selective RET inhibitors and use combination therapy that leads to more significant and durable anti-tumor responses in patients with RET rearranged cancers.

Emotions in Intergroup Contact: Incidental and Integral Emotions' Effects on Interethnic Bias Are Moderated by Emotion Applicability and Subjective Agency

This research draws from three distinct lines of research on the link between emotions and intergroup bias as springboard to integrative, new hypotheses. Past research suggests that emotions extrinsic to the outgroup (or “incidental”), and intrinsic to the outgroup (or “integral”), produce valence-congruent effects on intergroup bias when relevant or “applicable” to the outgroup (e.g., incidental/integral anger and ethnic outgroups). These emotions produce valence incongruent effects when irrelevant or “non-applicable” to the outgroup (e.g., incidental/integral sadness and happiness, and ethnic outgroups). Internally valid and ecologically sound tests of these contrasting effects are missing; hence we examined them experimentally in meaningful settings of interethnic contact. To this end, we hybridized established research paradigms in mood and intergroup contact research; this approach enabled us to use same materials and induction methods to instigate incidental and integral emotions in a single research design. In Experiment 1, White Australian students (N = 93) in in vivo real face-to-face contact with an ethnic tutor in their classroom displayed less interethnic bias when incidentally sad (vs. happy) or integrally happy (vs. sad). In Experiment 2, White American males' (N = 492) anti-Arab bias displayed divergent effects under incidental vs. integral (non-applicable) sadness/happiness and similar effects under incidental vs. integral (applicable) anger. The role of perceptions of agency in the emotion-inducing situation is also explored, tested, and explained drawing from mainstream emotion theory. As expected, integral and incidental applicable emotions caused valence congruent effects, at the opposite sides of the subjective agency spectrum, by encouraging the generalization of dislike from the outgroup contact partner to the outgroup as a whole. On the other hand, incidental-non-applicable emotions caused valence-incongruent effects on bias, under high agency conditions, by encouraging (non-partner-centered) heuristic processing. Because of the improved methodology, these effects can be regarded as genuine and not the byproduct of methodological artifacts. This theory-driven and empirically sound analysis of the interplay between emotion source, emotion applicability and subjective agency in intergroup contact can increase the precision of emotion-based bias reduction strategies by deepening understanding of the emotion conditions that lead to intergroup bias attenuation vs. exacerbation.

Factors Predicting Trial Engagement, Treatment Satisfaction, and Health-Related Quality of Life During a Web-Based Treatment and Social Networking Trial for Binge Drinking and Depression in Young Adults: Secondary Analysis of a Randomized Controlled Trial

BACKGROUND

Mental health and alcohol use problems are among the most common causes of disease burden in young Australians, frequently co-occur (comorbidity), and lead to significant lifetime burden. However, comorbidities remain significantly underdetected and undertreated in health settings. Digital mental health tools designed to identify at-risk individuals, encourage help-seeking, or deliver treatment for comorbidity have the potential to address this service gap. However, despite a strong body of evidence that digital mental health programs provide an effective treatment option for a range of mental health and alcohol use problems in young adults, research shows that uptake rates can be low. Thus, it is important to understand the factors that influence treatment satisfaction and quality-of-life outcomes for young adults who access e-mental health interventions for comorbidity.

OBJECTIVE

In this study, we seek to understand the factors that influence treatment satisfaction and quality-of-life outcomes for young adults who access e-mental health interventions for comorbid alcohol and mood disorders. The aim is to determine the importance of personality (ie, Big Five personality traits and intervention attitudes), affective factors (ie, depression, anxiety, and stress levels), and baseline alcohol consumption in predicting intervention trial engagement at sign-up, satisfaction with the online tool, and quality of life at the end of the iTreAD (Internet Treatment for Alcohol and Depression) trial.

METHODS

Australian adults (N=411) aged between 18 and 30 years who screened positive for depression and alcohol use problems signed up for the iTreAD project between August 2014 and October 2015. During registration, participants provided information about their personality, current affective state, alcohol use, treatment expectations, and basic demographic information. Subsequent follow-up surveys were used to gauge the ongoing trial engagement. The last follow-up questionnaire, completed at 64 weeks, assessed participants' satisfaction with web-based treatment and quality-of-life outcomes.

RESULTS

Multiple linear regression analyses were used to assess the relative influence of predictor variables on trial engagement, treatment satisfaction, and quality-of-life outcomes. The analyses revealed that the overall predictive effects of personality and affective factors were 20% or lower. Neuroticism constituted a unique predictor of engagement with the iTreAD study in that neuroticism facilitated the return of web-based self-assessments during the study. The return of incentivized follow-up assessments predicted treatment satisfaction, and state-based depression predicted variance in quality-of-life reports at study completion.

CONCLUSIONS

Our findings suggest that traditional predictors of engagement observed in face-to-face research may not be easily transferable to digital health interventions, particularly those aimed at comorbid mental health concerns and alcohol misuse among young adults. More research is needed to identify what determines engagement in this population to optimally design and execute digital intervention studies with multiple treatment aims.

In a Class on Their Own: Investigating the Role of Social Integration in the Association Between Social Class and Mental Well-Being

It has been established that people from lower social classes tend to have poorer mental well-being compared with people from higher classes. Research also suggests that people from the lower classes are also less socially integrated. This research investigated the role of social integration in the relationship between social class and mental well-being across three studies (Study 1 N = 15,028; Study 2 N = 1,946; Study 3 N = 461). Across all studies, social class had an indirect effect on mental well-being via social integration. Moderation results found that social integration buffers the negative impact of financial issues on mental well-being, social support buffers the effects of class on mental ill-health, and family support amplifies rather than reduces social class differences in mental well-being. We propose that although improving social integration has the potential to improve the mental well-being of lower class populations, some caveats need to be considered.

Explaining the association between subjective social status and mental health among university students using an impact ratings approach

Previous research has found a positive association between social class and mental health among university students. Various mediators of this association have been proposed. However, the extent to which students perceive these mediators as having an impact on their mental health has not been investigated. It is important to investigate this issue because students who do not perceive issues as having an impact on their mental health may not be motivated to address those issues. In the current study, 402 first-year undergraduate psychology students from a large Australian university indicated the extent to which 32 issues had a negative impact on their mental health over the past six months. Students rated lack of money, time management, coursework assessment items, lack of sleep, and course marks as having the largest impact on their mental health. Lack of money and time management mediated the positive association between subjective social status and mental health over (a) the past week and (b) the past month. Coursework assessment items and course marks mediated the positive association between subjective social status and satisfaction with the university experience. It is concluded that interventions should focus on these relatively high impact issues in order to address social class differences in students' mental health and university satisfaction.

Openness to Experience Moderates the Association Between Problem-Solving Style and Negative Affect

Abstract. Everyday problem-solving situations can be approached on an independent or interdependent basis. The current article investigated the moderating effects of openness to experience and self-efficacy on the relation between an independent versus interdependent problem-solving style and negative affect (stress, anxiety, depression, and neuroticism). Australian university students ( Ns = 399, 186, 337, and 248) and international academic researchers ( N = 199) took part in research studies examining the relations between personality, problem-solving-style, and mental health. Openness to experience moderated the association between problem-solving style and negative affect in all five studies. When openness was low, independent problem-solvers reported greater negative emotionality compared to interdependent problem-solvers. Further, the moderating effect of openness to experience on trait-based negative affectivity (i.e., neuroticism) was mediated by state-based negative emotional experiences of anxiety and stress. The moderating effect of self-efficacy appraisals was only statistically significant on specific anxiety about solving problems. Openness to experience seems to help alleviate the negative mental consequences of independent problem-solvers. These findings have implications for clinical practice with regard to building a therapeutic relationship and retaining clients.

Subjective status and perceived legitimacy across countries

The relationships between subjective status and perceived legitimacy are important for understanding the extent to which people with low status are complicit in their oppression. We use novel data from 66 samples and 30 countries (N = 12,788) and find that people with higher status see the social system as more legitimate than those with lower status, but there is variation across people and countries. The association between subjective status and perceived legitimacy was never negative at any levels of eight moderator variables, although the positive association was sometimes reduced. Although not always consistent with hypotheses, group identification, self-esteem, and beliefs in social mobility were all associated with perceived legitimacy among people who have low subjective status. These findings enrich our understanding of the relationship between social status and legitimacy.

Work Group Report: Perspectives in Diagnosis and Management of Exercise-Induced Bronchoconstriction in Athletes

Exercise-induced bronchoconstriction, otherwise known as exercise-induced bronchoconstriction with asthma or without asthma, is an acute airway narrowing that occurs as a result of exercise and can occur in patients with asthma. A panel of members from the American Academy of Allergy, Asthma & Immunology Sports, Exercise, & Fitness Committee reviewed the diagnosis and management of exercise-induced bronchoconstriction in athletes of all skill levels including recreational athletes, high school and college athletes, and professional athletes. A special emphasis was placed on the recommendations and regulations set forth by professional athletic organizations after a detailed review of their collective bargaining agreements, substance abuse policies, antidoping program manuals, and the World Anti-Doping Agency antidoping code. The recommendations in this review are based on currently available evidence in addition to providing guidance for athletes of all skill levels as well as their treating physicians to better understand which pharmaceutical and nonpharmaceutical management options are appropriate as well as which medications are permitted or prohibited, and the proper documentation required to remain compliant.

Young People's Voices Regarding the Use of Social Networking Sites to Plan for a Night Out Where Alcohol Is Involved

The risk of alcohol related harm is experienced disproportionality by young people aged 15-24 years. Harmful use of alcohol has serious effects on individual physical and mental wellbeing and is considered by the World Health Organization to be one of the main risk factors for poor health globally. It is crucial to understand the factors that influence drinking behavior in young people in order to inform prevention strategies to prevent problematic drinking. This is particularly paramount during the transition into young adulthood (around 18-25 years), when risky health behaviors are likely to become embedded. This pilot study adopted a qualitative descriptive methodology that facilitates exploration of what young people say about their own experiences and behavior, as it relates to SNS use and alcohol consumption. Semi-structured interviews were conducted in Newcastle, NSW Australia. An inductive, semantic approach to thematic analysis was selected to analyze the data as this method supported the exploratory nature of the pilot study and ensured that the themes identified were strongly linked to the data. Four main organizing themes that arose from the collected data were: organizing friends; safety amongst friends, planning not to plan; and different event - different plans. All of the participants stated they preferred to use Facebook Messenger™ to connect and share in a group conversation with peers. Convenience, cost and accessibility emerged as the main reasons for using SNSs to plan nights out. Planning for a night out using SNSs allows young people to impulsively plan and change plans - making planning fluid and asynchronous. To date, despite the global use of SNSs, the influence of SNSs in young adults' planning for events during which alcohol is served is relatively unknown. This pilot study gives us a some understanding of how young people use SNSs to plan and prepare for a night out where alcohol is served. Further research needs to be conducted to determine whether SNSs can be used effectively to promote health behavior change or be used as forums for advice seeking and support when attending events where alcohol is served, with the ultimate goal of lowering risky behaviors and thereby improving health outcomes for young people.

Workplace stress and resilience in the Australian nursing workforce: A comprehensive integrative review

This integrative review aimed to identify and synthesize evidence on workplace stress and resilience in the Australian nursing workforce. A search of the published literature was conducted using EMBASE, MEDLINE, CINAHL (EBSCO), PsycINFO, Web of Science, and Scopus. The search was limited to papers published in English from January 2008 to December 2018. The review integrated both qualitative and quantitative data into a single synthesis. Of the 41 papers that met the inclusion criteria, 65.85% (27/41) used quantitative data, 29.26% (12/41) used qualitative data, and 4.87% (2/41) used mixed methods. About 48.78% (20/41) of the papers addressed resilience issues, 46.34% (19/41) addressed workplace stress, and 4.87% (2/41) addressed both workplace stress and resilience. The synthesis indicated that nurses experience moderate to high levels of stress. Several individual attributes and organizational resources are employed by nurses to manage workplace adversity. The individual attributes include the use of work-life balance and organizing work as a mindful strategy, as well as self-reliance, passion and interest, positive thinking, and emotional intelligence as self-efficacy mechanisms. The organizational resources used to build resilience are support services (both formal and informal), leadership, and role modelling. The empirical studies on resilience largely address individual attributes and organizational resources used to build resilience, with relatively few studies focusing on workplace interventions. Our review recommends that research attention be devoted to educational interventions to achieve sustainable improvements in the mental health and wellbeing of nurses.

Management of Patients with Advanced Prostate Cancer: Report of the Advanced Prostate Cancer Consensus Conference 2019

BACKGROUND

Innovations in treatments, imaging, and molecular characterisation in advanced prostate cancer have improved outcomes, but there are still many aspects of management that lack high-level evidence to inform clinical practice. The Advanced Prostate Cancer Consensus Conference (APCCC) 2019 addressed some of these topics to supplement guidelines that are based on level 1 evidence.

OBJECTIVE

To present the results from the APCCC 2019.

DESIGN, SETTING, AND PARTICIPANTS

Similar to prior conferences, experts identified 10 important areas of controversy regarding the management of advanced prostate cancer: locally advanced disease, biochemical recurrence after local therapy, treating the primary tumour in the metastatic setting, metastatic hormone-sensitive/naïve prostate cancer, nonmetastatic castration-resistant prostate cancer, metastatic castration-resistant prostate cancer, bone health and bone metastases, molecular characterisation of tissue and blood, inter- and intrapatient heterogeneity, and adverse effects of hormonal therapy and their management. A panel of 72 international prostate cancer experts developed the programme and the consensus questions.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The panel voted publicly but anonymously on 123 predefined questions, which were developed by both voting and nonvoting panel members prior to the conference following a modified Delphi process.

RESULTS AND LIMITATIONS

Panellists voted based on their opinions rather than a standard literature review or formal meta-analysis. The answer options for the consensus questions had varying degrees of support by the panel, as reflected in this article and the detailed voting results reported in the Supplementary material.

CONCLUSIONS

These voting results from a panel of prostate cancer experts can help clinicians and patients navigate controversial areas of advanced prostate management for which high-level evidence is sparse. However, diagnostic and treatment decisions should always be individualised based on patient-specific factors, such as disease extent and location, prior lines of therapy, comorbidities, and treatment preferences, together with current and emerging clinical evidence and logistic and economic constraints. Clinical trial enrolment for men with advanced prostate cancer should be strongly encouraged. Importantly, APCCC 2019 once again identified important questions that merit assessment in specifically designed trials.

PATIENT SUMMARY

The Advanced Prostate Cancer Consensus Conference provides a forum to discuss and debate current diagnostic and treatment options for patients with advanced prostate cancer. The conference, which has been held three times since 2015, aims to share the knowledge of world experts in prostate cancer management with health care providers worldwide. At the end of the conference, an expert panel discusses and votes on predefined consensus questions that target the most clinically relevant areas of advanced prostate cancer treatment. The results of the voting provide a practical guide to help clinicians discuss therapeutic options with patients as part of shared and multidisciplinary decision making.

Examining the Dimensionality, Reliability, and Invariance of the Depression, Anxiety, and Stress Scale–21 (DASS-21) Across Eight Countries

This study evaluated the dimensionality, invariance, and reliability of the Depression, Anxiety, and Stress Scale–21 (DASS-21) within and across Brazil, Canada, Hong Kong, Romania, Taiwan, Turkey, United Arab Emirates, and the United States ( N = 2,580) in college student samples. We used confirmatory factor analyses to compare the fit of four different factor structures of the DASS-21: a unidimensional model, a three-correlated-factors model, a higher order model, and a bifactor model. The bifactor model, with three specific factors (depression, anxiety, and stress) and one general factor (general distress), presented the best fit within each country. We also calculated ancillary bifactor indices of model-based dimensionality of the DASS-21 and model-based reliability to further examine the validity of the composite total and subscale scores and the use of unidimensional modeling. Results suggested the DASS-21 can be used as a unidimensional scale. Finally, measurement invariance of the best fitting model was tested across countries indicating configural invariance. The traditional three-correlated-factors model presented scalar invariance across Canada, Hong Kong, Romania, Taiwan, and the United States. Overall, these analyses indicate that the DASS-21 would best be used as a general score of distress rather than three separate factors of depression, anxiety, and stress, in the countries studied.

Comparison of neutral outgassing of comet 67P/Churyumov-Gerasimenko inbound and outbound beyond 3 AU from ROSINA/DFMS

CONTEXT

Pre-equinox measurements of comet 67P/Churyumov-Gerasimenko with the mass spectrometer ROSINA/DFMS on board the Rosetta spacecraft revealed a strongly heterogeneous coma. The abundances of major and various minor volatile species were found to depend on the latitude and longitude of the nadir point of the spacecraft. The observed time variability of coma species remained consistent for about three months up to equinox. The chemical variability could be generally interpreted in terms of surface temperature and seasonal effects superposed on some kind of chemical heterogeneity of the nucleus.

AIMS

We compare here pre-equinox (inbound) ROSINA/DFMS measurements from 2014 to measurements taken after the outbound equinox in 2016, both at heliocentric distances larger than 3 AU. For a direct comparison we limit our observations to the southern hemisphere.

METHODS

We report the similarities and differences in the concentrations and time variability of neutral species under similar insolation conditions (heliocentric distance and season) pre- and post-equinox, and interpret them in light of the previously published observations. In addition, we extend both the pre- and post-equinox analysis by comparing species concentrations with a mixture of CO₂ and H₂O.

RESULTS

Our results show significant changes in the abundances of neutral species in the coma from pre- to post-equinox that are indicative of seasonally driven nucleus heterogeneity.

CONCLUSIONS

The observed pre- and post-equinox patterns can generally be explained by the strong erosion in the southern hemisphere that moves volatile-rich layers near the surface.

mHealth Interventions to Reduce Alcohol Use in Young People: A Systematic Review of the Literature

Harmful use of alcohol has serious effects on public health and is considered a significant risk factor for poor health. mHealth technology promotes health behavior change and enhances health through increased social opportunities for encouragement and support. It remains unknown whether these types of applications directly influence the health status of young people in reducing harmful levels of alcohol consumption. The purpose of this systematic review is to examine current evidence on the effectiveness of mHealth technology use in positively influencing alcohol-related behaviors of young people without known alcohol addiction. Relevant articles published from 2005 to January 2017 were identified through electronic searches of eight databases. Studies with interventions delivered by mHealth (social networking sites, SMS and mobile phone applications) to young people aged 12-26 years were included. Outcome measures were alcohol use, reduction in alcohol consumption or behavior change. Eighteen studies met the inclusion criteria. Interventions varied in design, participant characteristics, settings, length and outcome measures. Ten studies reported some effectiveness related to interventions with nine reporting a reduction in alcohol consumption. Use of mHealth, particularly text messaging (documented as SMS), was found to be an acceptable, affordable and effective way to deliver messages about reducing alcohol consumption to young people. Further research using adequately powered sample sizes in varied settings, with adequate periods of intervention and follow-up, underpinned by theoretical perspectives incorporating behavior change in young people's use of alcohol, is needed.

Is a system motive really necessary to explain the system justification effect? A response to Jost (2019) and Jost, Badaan, Goudarzi, Hoffarth, and Mogami (2019)

The debate between the proponents of SIMSA and SJT does not pivot on whether system justification occurs - we all agree that system justification does occur. The issue is why it occurs? System justification theory (SJT; Jost & Banaji, 1994, British Journal of Social Psychology, 33, 1) assumes that system justification is motivated by a special system justification motive. In contrast, the social identity model of system attitudes (SIMSA; Owuamalam, Rubin, & Spears, , Current Directions in Psychological Science, 27, 2) argues that there is insufficient conclusive evidence for this special system motive, and that system justification can be explained in terms of social identity motives, including the motivation to accurately reflect social reality and the search for a positive social identity. Here, we respond to criticisms of SIMSA, including criticisms of its social reality, ingroup bias, and hope for future ingroup status explanations of system justification. We conclude that SJT theorists should decide whether system justification is oppositional to, or compatible with social identity motives, and that this dilemma could be resolved by relinquishing the theoretically problematic notion of a system justification motivation.

Revisiting 25 years of system motivation explanation for system justification from the perspective of social identity model of system attitudes

Do the disadvantaged have an autonomous system justification motivation that operates against their personal and group interests? System justification theory (SJT; Jost & Banaji, 1994, Br. J. Soc. Psychol, 33, 1) proposes that they do and that this motivation helps to (1) reduce cognitive dissonance and associated uncertainties and (2) soothe the pain that is associated with knowing that one's group is subject to social inequality. However, 25 years of research on this system justification motivation has given rise to several theoretical and empirical inconsistencies. The present article argues that these inconsistencies can be resolved by a social identity model of system attitudes (SIMSA; Owuamalam, Rubin, & Spears, 2018, Curr. Dir. Psychol. Sci, 27, 91). SIMSA assumes that instances of system justification are often in alignment with (rather than opposed to) the interests of the disadvantaged. According to SIMSA, the disadvantaged may support social systems (1) in order to acknowledge social reality, (2) when they perceive the wider social system to constitute a superordinate ingroup, and (3) because they hope to improve their ingroup's status through existing channels in the long run. These propositions are corroborated by existing and emerging evidence. We conclude that SIMSA offers a more coherent and parsimonious explanation for system justification than does SJT.

Abstract A074: Aberrant activation of a gastrointestinal transcriptional circuit in prostate cancer mediates castration resistance

Prostate cancer exhibits a remarkable lineage-specific dependence on androgen signaling. Lineage-directed therapy using androgen deprivation has been the mainstay of prostate cancer treatment for 70 years. Castration resistance involves reactivation of androgen signaling or activation of alternative lineage programs to bypass androgen requirement. Our studies found that an aberrant gastrointestinal lineage transcriptome is expressed in ~5% of primary prostate cancer that is characterized by abbreviated response to androgen deprivation therapy and in ~30% of castration-resistant prostate cancer. This program is governed by a transcriptional circuit consisting of HNF4G and HNF1A. Cistrome and chromatin analyses revealed that HNF4G is a pioneer factor that generates and maintains enhancer landscape at gastrointestinal lineage genes, independent of AR signaling. In HNF4G/1A-negative prostate cancer, exogenous expression of HNF4G at physiologic levels recapitulates the GI transcriptome, chromatin landscape and leads to relative castration resistance.
