Suicidality associated with decreased help-seeking attitudes in college students: Implications for identifying and treating at-risk students.

Suicide is a leading cause of death in college-aged youth, yet only half of all college students report engaging in professional mental health help-seeking. We examined how the various aspects of young adults' suicidality were associated with their openness to pursue professional mental health care in the future (i.e., "future help-seeking intentions"). Multilevel binary logistic regressions were tested in a sample of 24,446 U.S. college undergraduates with suicidality. The moderating effect of past service utilization on future help-seeking intentions was also tested. Strikingly, young people reporting past-year suicidal ideation, past-year suicidal attempts, and self-reported likelihood of a future suicide attempt demonstrated decreased likelihood of future help-seeking intentions, while those reporting prior diagnosis of a mental health condition and/or past service utilization demonstrated an increased likelihood. Past service utilization also significantly moderated the effect of suicide disclosure, such that youth reporting prior disclosure and prior professional treatment-seeking demonstrated greater odds of future help-seeking intentions relative to those who had disclosed suicidality but never utilized professional services. In order to mitigate the mental health crisis facing youth, further exploration is necessary to understand why students with suicidality do not report openness to seek help. It is also imperative to develop and implement novel strategies to identify at-risk students, understand and alleviate relevant barriers to treatment, and promote positive help-seeking attitudes and behaviors.

Telephone-Based Rehabilitation Intervention to Optimize Activity Participation After Breast Cancer: A Randomized Clinical Trial.

Importance: Following treatment, breast cancer survivors face challenges participating in valued activities. Objective: To determine whether a telephone-based coaching rehabilitation intervention enhances activity participation in the year following breast cancer treatment. Design, Setting, and Participants: In this multisite, single-blind randomized clinical trial (Optimizing Functional Recovery of Breast Cancer Survivors), recruitment occurred between August 28, 2019, and April 30, 2022. Data collection was completed by April 1, 2023. Participants were recruited from 2 cancer centers (Dartmouth College and the University of Alabama at Birmingham) and via social media advertisements. Women aged 18 years or older who had completed primary treatment for stage I to III breast cancer within 1 year and reported participation restrictions were eligible to participate. Randomization was stratified by site, treatment, and time since treatment. Interventions: The intervention, delivered via telephone over 9 sessions, used behavioral activation and problem-solving principles to promote activity participation. The education-based attention control condition was delivered via telephone at matched intervals. Main Outcomes and Measures: The primary outcome was participation, assessed using 5 measures, including Patient-Reported Outcomes Measurement Information System (PROMIS) social participation-satisfaction measure. One individualized outcome allowed participants to specify activities for which they wanted to foster recovery. Outcomes were collected by telephone by blinded coordinators at baseline and at 8, 20, and 44 weeks. The individualized outcome was assessed at the first and last intervention and control session. Results: Among 1996 patients identified, 303 were eligible and enrolled. Of these, 284 women (94%; mean [SD] age, 56.1 [10.2] years) completed baseline assessments and were randomized, and 81% or more of each group completed the final assessment with no adverse events. Of those who completed the final assessment, 118 of 114 (82%) were in the intervention group, and 113 of 140 (81%) were attention control participants. Between-group differences were not statistically significant for the main measures of PROMIS satisfaction (week 20: Cohen d, 0.1 [95% CI, -0.09 to 0.29] and week 44: Cohen d, -0.08 [95% CI, -0.27 to 0.11]) and ability (week 20: Cohen d, 0.15 [95% CI, -0.06 to 0.37] and week 44: Cohen d, -0.08 [95% CI, -0.27 to 0.11]). On the individualized outcome, intervention participants reported significantly greater improvements in activity satisfaction (Cohen d, 0.76 [95% CI, 0.48-1.02]) and performance (Cohen d, 0.60 [95% CI, 0.32-0.87]). Conclusions and Relevance: In this randomized clinical trial, the intervention catalyzed greater improvements in self-selected activity participation and goal disengagement but did not otherwise accelerate recovery compared with the control condition. Future research should determine what intervention features may lead to the greatest reductions in participation restrictions and other measures that may detect functional recovery. Trial Registration: ClinicalTrials.gov Identifier: NCT03915548.

Strategies to support cancer survivors at work: content analysis of cancer survivor, healthcare provider, and employer perspectives.

PURPOSE: To (1) describe the challenges identified by cancer survivors, healthcare providers, and employers related to work maintenance and optimization during and after cancer treatment and (2) identify strategies that can address those challenges. METHODS: We conducted content analysis of semi-structured interview data collected from cancer survivors, healthcare providers, and employers regarding workplace challenges that cancer survivors face and strategies to address them. Challenges and strategies were summarized according to whether they related to the cancer survivor, the work demands, or the work environment. RESULTS: Forty-five total participants identified challenges and strategies primarily related to the cancer survivor's signs and symptoms of treatment. Healthcare providers (n = 17) focused primarily on challenges and strategies related to the cancer survivor, while employers (n = 5) focused on the work environment-especially policies and procedures that facilitate time off work and the importance of bidirectional communication between cancer survivors and employers. Cancer survivors (n = 23) identified challenges and suggestions in all three categories, though they uniquely focused on challenges relating to work demands and adjustments to those demands that would facilitate employment maintenance. CONCLUSIONS: Efforts to address the many challenges that cancer survivors experience at work should include the views of cancer survivors, healthcare providers, and employers reflecting their respective domains of expertise in work demands, cancer survivors' medical care, and the work environment. IMPLICATIONS FOR CANCER SURVIVORS: Survivors and healthcare providers are able to address many side effects that can create work challenges, but improved collaboration between survivors and employers may identify ways to modify work demands and environments to maximize employment maintenance.

Behavioral Activation: Values-Aligned Activity Engagement as a Transdiagnostic Intervention for Common Geriatric Conditions.

Scalable, transdiagnostic interventions are needed to meet the needs of a growing population of older adults experiencing multimorbidity and functional decline. Behavioral activation (BA) is a pragmatic, empirically supported treatment for depression that focuses on increasing engagement in values-aligned activities. We propose BA is an ideal transdiagnostic intervention approach for older adults because it (a) specifically targets activity restriction, a shared characteristic of common conditions of aging; and (b) has strong potential for scalability through delivery by a broad range of clinician and nonclinician interventionists and via telehealth. We describe the history of BA and review recent literature demonstrating impacts beyond depression including on cognition, social isolation, and disability. We also describe the feasibility of delivering BA across interventionists, settings, and modalities. Our approach advances scholarship by proposing BA as a scalable, transdiagnostic behavioral intervention to address functional decline in older adults with common geriatric conditions.

Adapting natural language processing and sentiment analysis methods for an intervention in older adults: Positive perceptions of health and technology.

Background: Older adults frequently participate in behavior change studies, yet it is not clear how to quantify a potential relationship between their perception of the intervention and its efficacy. Research Aim: We assessed the relationship between participant sentiment toward the intervention from follow-up interviews with physical activity and questionnaires for the perception of health. Methods: Sentiment was calculated using the transcripts of exit interviews through a bag of words approach defined as the sum of positive and negative words in 28 older adults with obesity (body mass index ≥30kg/m2). Results: Mean age was 73 years (82% female), and 54% lost ≥5% weight loss. Through linear regression we describe a significant association between positive sentiment about the intervention and weight loss; positive sentiment on technology and change in PROMIS-10 physical health and reduced physical activity time, while controlling for sex and age. Conclusions: This analysis demonstrates that sentiment analysis and natural language processing in program review identified an association between perception and topics with clinical outcomes.

A Process Evaluation of Intervention Delivery for a Cancer Survivorship Rehabilitation Clinical Trial Conducted during the COVID-19 Pandemic.

The purpose of the present study was to conduct a process evaluation of intervention delivery for a randomized controlled trial (RCT) conducted during the COVID-19 pandemic (NCT03915548). The RCT tested the effects of a telephone-delivered behavioral intervention on changes in breast cancer survivors' satisfaction with social roles and activities, as compared to an attention control condition. This process evaluation examined (a) fidelity monitoring scores; (b) participants' perceived benefit ratings for gaining confidence, reducing distress, adjusting habits and routines, setting goals, and increasing exercise; and (c) field notes, email communications, and transcripts of coach supervision and debriefing sessions. The behavioral and attention control conditions were delivered with a high degree of fidelity (global quality rating score for the BA/PS condition was M = 4.6 (SD = 0.6) and M = 4.9 (SD = 0.3) for the attention control condition, where "5" is the highest rating). The behavioral intervention participants perceived greater benefits than the control participants pertaining to goal setting, t(248) = 5.73, p = <0.0001, adjusting habits and routines, t(248) = 2.94, p = 0.0036, and increasing exercise, t(248) = 4.66, p = <0.0001. Moreover, coaches' perceptions regarding the behavioral intervention's therapeutic aspects aligned with the study's a priori conceptual model including the use of a structured process to set small, observable goals and facilitate the independent use of problem-solving skills. However, coaches also noted that aspects of the attention control condition, including the perceived relevance of the educational content and opportunities for social support, may have made it more therapeutically potent than intended. The pandemic may have affected the activity goals behavioral intervention participants could set as well as augmented the relevancy of social support provided in both conditions.

Enhancing Efficiency and Reach Using Facebook to Recruit Breast Cancer Survivors for a Telephone-Based Supportive Care Randomized Trial During the COVID-19 Pandemic.

PURPOSE: Evidence supporting social media-based recruitment of cancer survivors is limited. This paper describes how we used Facebook during the COVID-19 pandemic to augment our recruitment of breast cancer survivors for our two-site telephone-based randomized clinical trial (RCT) at Dartmouth-Hitchcock Medical Center and the University of Alabama at Birmingham. METHODS: Originally a two-site RCT of a telephone-delivered breast cancer survivorship intervention, we extended our clinic-based recruitment to Facebook. Participant characteristics, geographic reach, and baseline outcomes were compared across recruitment sources (ie, two clinics and Facebook) using descriptive statistics and effect sizes. RESULTS: Enrollment rates (20%-29%) were comparable across recruitment sources. The 21-month Facebook marketing campaign accounted for 59% (n = 179/303) of our total sample and had the greatest geographic reach, recruiting women from 24 states. The Facebook campaign reached a total of 51,787 unique individuals and cost $88.44 in US dollars (USD) per enrolled participant. Clinic samples had a greater proportion of women who were widowed (8% v 1%; P = .03) and Facebook had a higher proportion of women with a household income over $40,000 USD (83% v 71%; P = .02). There were no statistically significant differences between Facebook and the two clinics on baseline survey scores. CONCLUSION: Augmenting traditional recruitment with Facebook increased our RCT's geographic and sociodemographic reach and supported meeting recruitment goals in a timely way. In the wake of the COVID-19 pandemic, cancer survivorship researchers should consider using social media as a recruitment strategy while weighing the advantages and potential biases introduced through such strategies.

Long COVID and psychological distress in young adults: Potential protective effect of a prior mental health diagnosis.

BACKGROUND: Although young adulthood is a period characterized by marked psychological vulnerability, young adults are typically considered to be in good physical health and are therefore understudied with respect to the effects of COVID-19 infection and long COVID. The present study examined associations between post-acute sequelae of COVID-19 (PASC) and serious psychological distress during young adulthood, and tested whether prior mental health diagnosis moderated this association. METHODS: Participants were 44,652 young adults who completed the Spring 2022 administration of the American College Health Association-National College Health Assessment III (ACHA-NCHA). Blockwise logistic regressions tested the odds of meeting the clinical threshold for serious psychological distress. RESULTS: PASC was associated with 53 % increased likelihood of meeting the clinical threshold for serious psychological distress. Among young adults with a prior mental health diagnosis, PASC predicted 36 % increased odds of serious psychological distress; among those without a diagnosis, PASC predicted 81 % increased odds. LIMITATIONS: PASC was assessed using a single self-report item rather than a clinical diagnosis of specific symptomatology. The analyses were cross-sectional and relied on concurrent reports of PASC and psychological distress which precluded us from making claims regarding directionality of the associations. The outcome of generalized psychological distress limited us from generating targeted treatment recommendations. CONCLUSIONS: PASC may confer elevated psychological distress among young adults. The association of PASC to serious psychological distress was stronger in young adults without a mental health diagnosis than those with a diagnosis. Prior experience with mental illness may mitigate the psychological burden of long-term symptomatology.

Exploring Acceptability of Employment Interventions to Support People Living With Cancer: Qualitative Study of Cancer Survivors, Health Care Providers, and Employers.

BACKGROUND: Employment contributes to cancer survivors' quality of life, but this population faces a variety of challenges when working during and after treatment. Factors associated with work outcomes among cancer survivors include disease and treatment status, work environment, and social support. While effective employment interventions have been developed in other clinical contexts, existing interventions have demonstrated inconsistent effectiveness in supporting cancer survivors at work. We conducted this study as a preliminary step toward program development for employment support among survivors at a rural comprehensive cancer center. OBJECTIVE: We aimed (1) to identify supports and resources that stakeholders (cancer survivors, health care providers, and employers) suggest may help cancer survivors to maintain employment and (2) to describe stakeholders' views on the advantages and disadvantages of intervention delivery models that incorporate those supports and resources. METHODS: We conducted a descriptive study collecting qualitative data from individual interviews and focus groups. Participants included adult cancer survivors, health care providers, and employers living or working in the Vermont-New Hampshire catchment area of the Dartmouth Cancer Center in Lebanon, New Hampshire. We grouped interview participants' recommended supports and resources into 4 intervention delivery models, which ranged on a continuum from less to more intensive to deliver. We then asked focus group participants to discuss the advantages and disadvantages of each of the 4 delivery models. RESULTS: Interview participants (n=45) included 23 cancer survivors, 17 health care providers, and 5 employers. Focus group participants (n=12) included 6 cancer survivors, 4 health care providers, and 2 employers. The four delivery models were (1) provision of educational materials, (2) individual consultation with cancer survivors, (3) joint consultation with both cancer survivors and their employers, and (4) peer support or advisory groups. Each participant type acknowledged the value of providing educational materials, which could be crafted to improve accommodation-related interactions between survivors and employers. Participants saw usefulness in individual consultation but expressed concern about the costs of program delivery and potential mismatches between consultant recommendations and the limits of what employers can provide. For joint consultation, employers liked being part of the solution and the possibility of enhanced communication. Potential drawbacks included additional logistical burden and its perceived generalizability to all types of workers and workplaces. Survivors and health care providers viewed the efficiency and potency of peer support as benefits of a peer advisory group but acknowledged the sensitivity of financial topics as a possible disadvantage of addressing work challenges in a group setting. CONCLUSIONS: The 3 participant groups identified both common and unique advantages and disadvantages of the 4 delivery models, reflecting varied barriers and facilitators to their potential implementation in practice. Theory-driven strategies to address implementation barriers should play a central role in further intervention development.

Linking social and built environmental factors to leisure-time physical activity in rural cancer survivors.

BACKGROUND: This study explored associations between social and built environmental factors and leisure-time physical activity (LTPA) in rural cancer survivors (RCS) and whether these associations differed by exercise stage of change (SOC). METHOD: RCS (n = 219) completed questionnaires assessing LTPA, SOC, and social (social status, connectedness, support) and environmental (home environment, neighborhood environment) factors. Linear regression models examined associations between social and built environmental factors and LTPA and tested for moderation by SOC. RESULTS: Half (50.7%) of RCS were physically active, and 49.3% were not active. Social factors positively associated with LTPA included subjective social status in the community (B = 89.0, P = .014) and in the United States (B = 181.3, P < .001), social connectedness (B = 122.3, P = .024), and social support for physical activity from family (B = 41.9, P < .001) and friends (B = 44.3, P < .001). Environmental factors positively associated with LTPA included the home environment (B = 111.2, P < .001), perceived environmental support for PA (B = 355.4, P = .004), and neighborhood attributes, including bicycling infrastructure (B = 191.3, P = .003), proximity to recreation facilities (B = 140.1, P = .021), traffic safety (B = 184.5, P = .025), and aesthetics (B = 342.6, P < .001). SOC statistically significantly moderated the association between social status in the United States and LTPA (B = 160.3, P = .031). CONCLUSIONS: Social and built environmental factors were consistently linked with LTPA and provide context for multilevel interventions promoting LTPA in RCS.

COVID-19-related direct and vicarious racial discrimination: Associations with psychological distress among U.S. college students.

BACKGROUND: The COVID-19 pandemic has been accompanied by a myriad of racist incidents targeting minorities in the U.S. Young adults are susceptible to direct and vicarious (indirect) pandemic-related racial discrimination. We sought to examine associations between both types of discrimination experiences and psychological distress among college students across different racial groups. METHODS: We analyzed self-reported data from 64,041 undergraduate students from the Spring 2021 American College Health Association-National College Health Assessment. Logistic regression examined odds of severe distress based on self-reported exposure to direct and vicarious racial discrimination. RESULTS: Even after controlling for sociodemographic characteristics and prior mental health diagnoses, there was a significant association between direct discrimination and distress among Asian (AOR: 1.3, p < 0.001), Hispanic (AOR: 1.6, p < 0.001), and Multiracial (AOR: 1.4, p < 0.001) students. Vicarious discrimination was significantly associated with distress among White (AOR: 1.4, p < 0.001), Asian (AOR: 1.4, p < 0.001), Hispanic (AOR: 1.5, p < 0.001), and Multiracial (AOR: 1.3, p < 0.001) students. Further analysis considering distress as a continuous measure revealed a significant association between vicarious discrimination and distress for Black participants (ß = 0.9, p < 0.001). LIMITATIONS: Self-reported variables are susceptible to recall bias. Minority racial group analyses may be underpowered. CONCLUSIONS: Our findings reveal an overall link between both direct and vicarious racial discrimination and distress across several racial groups. Further studies should examine effective mental health interventions and anti-racism initiatives to support students who have experienced direct or vicarious discrimination due to COVID-19.

Prevalence and Correlates of Prescription Stimulant Misuse Among US College Students: Results From a National Survey.

Objective: There is a high prevalence of prescription stimulant misuse (PSM) among college students in the United States (US). Preventing and identifying PSM requires an understanding of risk factors and correlates, but large-scale surveys regarding this issue have been lacking. We present the largest multi-institution study to date on the correlates of PSM among US college students.Methods: We performed a secondary analysis of the 2017 American College Health Association-National College Health Assessment (ACHA-NCHA), an annual national survey on the demographics, health, and academic experiences of US college students. Logistic regression models examined associations between past-year PSM in 40,645 undergraduate college students and hypothesized risk factors.Results: PSM was reported in 8% of college students. PSM was associated with past-year diagnosis or treatment of depression (adjusted odds ratio [AOR] = 1.16; 99% CI, 1.01-1.33), anorexia (AOR = 1.44; 99% CI, 1.02-2.03), attention-deficit/hyperactivity disorder (AOR = 1.66; 99% CI, 1.41-1.95), and substance use disorder/other addiction (AOR = 1.79; 99% CI, 1.30-2.46). The odds of PSM were 5.5 times higher for students who endorsed past-month use of "Legal drugs" and 8 times higher for students who endorsed past-month use of "Illegal drugs" than for those who did not. Other factors associated with PSM included academic difficulty, daytime sleepiness, fraternity or sorority involvement, White race, and cis-male gender.Conclusions: This study identifies many potential risk factors for PSM among US undergraduate college students. Targeted outreach, prevention, and clinical management are discussed. As the COVID-19 pandemic has exacerbated psychiatric distress, sleep difficulties, substance use, and attentional challenges among college students, this study may serve as a baseline for future studies examining the impact of COVID-19 on PSM among college students.

Association Between College Course Delivery Model and Rates of Psychological Distress During the COVID-19 Pandemic.

Importance: College students in the US have been heavily affected by the COVID-19 pandemic. In addition to increased rates of depression and anxiety, college students have faced unprecedented stressors, such as geographic relocation and abrupt conversion from in-person classes to online classes. Objective: To study the association between course delivery model and psychological distress among US college students. Design, Setting, and Participants: This cross-sectional analysis used national data from the American College Health Association-National College Health Assessment III data set. Data were gathered from a web-based survey administered from January to early June 2021 to full-time US college students attending 4-year programs. Exposure: Course delivery model was self-reported. Main Outcomes and Measures: Psychological distress was measured using the Kessler Screening Scale for Psychological Distress. Results: This study evaluated 59 250 full-time undergraduate students (68.1% women; 51.5% White students; mean [SD] age, 21.2 [4.3] years); 3.5% attended fully in-person classes, 61.2% attended fully online classes, and 35.3% attended a mixed format of in-person and online classes. Students who attended classes fully online reported higher levels of psychological distress than those who attended a mix of online and in-person classes (b = 0.76 [99% CI, 0.64-0.88]; P < .001). This association remained significant after controlling for geographic region, year in school, gender, race and ethnicity, food security, current anxiety and/or depressive disorders, COVID-19 concerns, and residence (living on campus, off campus with family, or other off-campus arrangements) (b = 0.18 [99% CI, 0.04-0.31]; P = .001), as well as time spent socializing with friends (b = 0.13 [99% CI, 0.002-0.26]; P = .009). Conclusions and Relevance: The findings of this study suggest that mental health professionals may wish to consider the association of course delivery models with mental health outcomes when working with college students. Colleges should be aware of the mental health burden associated with attending fully online classes and consider possible in-person components and supports for students.

Testing positive, losing a loved one, and financial hardship: Real-world impacts of COVID-19 on US college student distress.

BACKGROUND: The COVID-19 pandemic has taken a particularly heavy toll on U.S. college students. In addition to facing academic-related stress and social pressures, these individuals are now increasingly susceptible to experiences such as contracting the virus, losing loved ones to COVID-19, or facing financial hardship due to the pandemic. The effects of such personal, pandemic-related experiences on young adult mental health - and the inherent racial disparities within these outcomes - remain largely understudied. METHODS: We analyzed 65,568 undergraduate students from the Spring 2021 American College Health Association-National College Health Assessment (ACHA-NCHA). RESULTS: The rates of the aforementioned COVID-19-related stressors were unevenly distributed across racial groups. A logistic regression analysis to identify predictors of moderate and serious psychological distress revealed that participants who had experienced the death of a loved one had 1.14 times greater odds of developing psychological distress (p < 0.0001). Those who experienced financial hardship had an odds ratio of 1.78 (p < 0.0001). Surprisingly, testing positive for COVID-19 was associated with an odds ratio of 0.82 of psychological distress (p < 0.0001). LIMITATIONS: Self-reported measures are susceptible to recall bias and misinterpretation. Exposure and outcome variables were measured simultaneously in this cross-sectional study which limits inference on causality. CONCLUSIONS: Financial burdens and bereavement are especially impactful stressors among college students during the pandemic, whereas contracting COVID-19 seemingly exhibits less impact on distress levels. When addressing student wellbeing, institutions should consider prioritizing the implementation of resources to support individuals affected by pandemic-related financial and familial losses.

Human Colon Cancer-Derived Clostridioides difficile Strains Drive Colonic Tumorigenesis in Mice.

Defining the complex role of the microbiome in colorectal cancer and the discovery of novel, protumorigenic microbes are areas of active investigation. In the present study, culturing and reassociation experiments revealed that toxigenic strains of Clostridioides difficile drove the tumorigenic phenotype of a subset of colorectal cancer patient-derived mucosal slurries in germ-free ApcMin/+ mice. Tumorigenesis was dependent on the C. difficile toxin TcdB and was associated with induction of Wnt signaling, reactive oxygen species, and protumorigenic mucosal immune responses marked by the infiltration of activated myeloid cells and IL17-producing lymphoid and innate lymphoid cell subsets. These findings suggest that chronic colonization with toxigenic C. difficile is a potential driver of colorectal cancer in patients. SIGNIFICANCE: Colorectal cancer is a leading cause of cancer and cancer-related deaths worldwide, with a multifactorial etiology that likely includes procarcinogenic bacteria. Using human colon cancer specimens, culturing, and murine models, we demonstrate that chronic infection with the enteric pathogen C. difficile is a previously unrecognized contributor to colonic tumorigenesis. See related commentary by Jain and Dudeja, p. 1838. This article is highlighted in the In This Issue feature, p. 1825.

Murine fecal microbiota transfer models selectively colonize human microbes and reveal transcriptional programs associated with response to neoadjuvant checkpoint inhibitors.

Human gut microbial species found to associate with clinical responses to immune checkpoint inhibitors (ICIs) are often tested in mice using fecal microbiota transfer (FMT), wherein tumor responses in recipient mice may recapitulate human responses to ICI treatment. However, many FMT studies have reported only limited methodological description, details of murine cohorts, and statistical methods. To investigate the reproducibility and robustness of gut microbial species that impact ICI responses, we performed human to germ-free mouse FMT using fecal samples from patients with non-small cell lung cancer who had a pathological response or nonresponse after neoadjuvant ICI treatment. R-FMT mice yielded greater anti-tumor responses in combination with anti-PD-L1 treatment compared to NR-FMT, although the magnitude varied depending on mouse cell line, sex, and individual experiment. Detailed investigation of post-FMT mouse microbiota using 16S rRNA amplicon sequencing, with models to classify and correct for biological variables, revealed a shared presence of the most highly abundant taxa between the human inocula and mice, though low abundance human taxa colonized mice more variably after FMT. Multiple Clostridium species also correlated with tumor outcome in individual anti-PD-L1-treated R-FMT mice. RNAseq analysis revealed differential expression of T and NK cell-related pathways in responding tumors, irrespective of FMT source, with enrichment of these cell types confirmed by immunohistochemistry. This study identifies several human gut microbial species that may play a role in clinical responses to ICIs and suggests attention to biological variables is needed to improve reproducibility and limit variability across experimental murine cohorts.

Younger Age Impacts Perceptions of Care Received in the Emergency Department Among Women with Spontaneous Coronary Artery Dissection.

Background: Spontaneous coronary artery dissection (SCAD) is a nonatherosclerotic etiology of acute coronary syndrome (ACS) that primarily affects younger women with few traditional cardiovascular disease risk factors. The primary objective of this study was to evaluate how younger age impacts the perception of care women receive in the emergency department (ED) at the time of their first or only SCAD. Methods: SCAD survivors were recruited using SCAD Alliance social media platforms to complete a one-time online survey regarding their experiences of seeking treatment for SCAD in the ED and their post-SCAD recovery. A total of 409 participants consented to participate in the parent study and data collected from the 367 participants who reported female gender were further analyzed. Results: Fewer participants <50 years old than would be expected under the null hypothesis (i.e., 65.5% observed vs. 71.2% expected, p = 0.009) reported perceived serious treatment by ED staff, more participants <50 years than would be expected under the null hypothesis (i.e., 12.0% observed vs. 9.3% expected, p = 0.049) reported perceived dismissive treatment by ED staff, and more participants <50 years than would be expected under the null hypothesis (i.e., 13.3% observed vs. 10.8% expected, p = 0.02) reported discharge from the ED without a diagnosis. Conclusions: Results of this study highlight the different experiences of younger SCAD survivors' engaging with providers in the ED. Further research regarding strategies for increasing ED providers' clinical interrogation of SCAD when treating and evaluating younger female patients presenting with ACS symptoms is indicated.

Prevalence and correlates of mental health symptoms and disorders among US international college students.

Objective: This study assessed the prevalence and correlates of mental health (MH) symptoms and diagnoses in international college students in the United States. Participants: The sample included 44,851 degree-seeking undergraduate students (42,428 domestic students and 2,423 international students). Methods: Logistic regression analyses were conducted using international student status to predict MH symptoms and diagnoses from the Spring 2017 administration of the ACHA-National College Health Assessment (ACHA-NCHA). Results: International students were less likely than domestic students to report a diagnosis of anxiety, comorbid depression and anxiety, or other psychiatric diagnoses. International students were more likely to report suicide attempts and feeling overwhelmingly depressed. Conclusions: Among international students studying in the US, lower rates of MH diagnoses despite higher rates of depressive symptoms and suicide attempts mirror similar trends seen in American-born minority students. University campuses should consider culturally sensitive and targeted psychoeducation, mental health services, and outreach programming.

Preexisting Depression and Daytime Sleepiness in Women and Men.

BACKGROUND: Sleep problems can persist following the treatment of depression and remission of symptoms. The extent to which having a previous history of depression may be associated with current daytime sleepiness is largely unknown. METHODS: Data were obtained from the spring 2017 American College Health Association-National College Health Assessment (ACHA-NCHA) survey (92 institutions) which assessed self-reported health in U.S. college students (n = 41,670). Among the sample, 93.5% were 18-24 year of age, and 69.6% women. Logistic regression estimated the association between reported prior lifetime diagnosis of depression and daytime sleepiness from the past 7 days, while adjusting for depressive symptoms and antidepressant use from the past year. Unadjusted and adjusted logistic regression models stratified by gender were performed. RESULTS: Among those who reported problems with sleepiness, 31.6% women and 19.4% men had a preexisting depression diagnosis. Individuals with preexisting depression were more likely than those without this diagnosis to report sleepiness problems (women: OR = 1.4, CI = 1.3-1.6, p < .001; men: OR = 1.2, CI = 1.0-1.4, p < .01). However, this association differed significantly by gender, with women with a preexisting depression diagnosis having a 13.0% greater likelihood of sleepiness compared to men. CONCLUSIONS: Those with a preexisting depression diagnosis, and specifically women, may be at risk for daytime sleepiness even in the absence of current depressive mood-related symptoms. Given that many individuals are at risk for daytime sleepiness, mental health initiatives, including those on college campuses, should incorporate sleep hygiene within their programming.

Binge drinking and sexual risk behavior among US sexual and gender minority college students.

BACKGROUND AND OBJECTIVES: Binge drinking and sexual risk behaviors have historically been associated with lesbian, gay, bisexual, and transgender (LGBT) adults; however, few studies have described this association among broader sexual and gender minority (SGM) students, who often identify outside of LGBT (e.g., asexual, queer). This study examined the relationship between binge drinking and sexual risk behaviors among SGM versus non-SGM college students. METHODS: A retrospective analysis was conducted with cross-sectional data from the Spring 2017 American College Health Association-National College Health Assessment (ACHA-NCHA) survey among US undergraduates (n = 47,821) across 92 institutions. Binge drinking was measured as more than five drinks consumed the last time the student socialized; sexual risk behavior was measured as the number of sexual partners in the past 12 months. RESULTS: Numerous undergraduates nationally identify as SGM (19.9%), with bisexual (32.7%), other SGM (26.1%), and asexual (25.4%) students comprising the largest subgroups. Prevalent among both SGM (28.1%) and non-SGM (29.6%) students, binge drinking had a significant main effect on the number of sexual partners. A significant interaction effect was observed between SGM identity and binge drinking on the number of sexual partners, such that this association was stronger in SGM versus non-SGM students. This effect remained significant across multiple SGM subgroups. DISCUSSION AND CONCLUSIONS: SGM students are more prevalent and diverse than previously reported. While prevalent overall, binge drinking may be uniquely sexualized among SGM students. SCIENTIFIC SIGNIFICANCE: In the first large-scale study assessing drinking among disaggregated SGM college students, data suggest tailoring alcohol interventions to SGM students, particularly those identifying outside of LGBT.
