Epigenetic tuning of PD-1 expression improves exhausted T cell function and viral control.

PD-1 is a key negative regulator of CD8+ T cell activation and is highly expressed by exhausted T cells in cancer and chronic viral infection. Although PD-1 blockade can improve viral and tumor control, physiological PD-1 expression prevents immunopathology and improves memory formation. The mechanisms driving high PD-1 expression in exhaustion are not well understood and could be critical to disentangling its beneficial and detrimental effects. Here, we functionally interrogated the epigenetic regulation of PD-1 using a mouse model with deletion of an exhaustion-specific PD-1 enhancer. Enhancer deletion exclusively alters PD-1 expression in CD8+ T cells in chronic infection, creating a 'sweet spot' of intermediate expression where T cell function is optimized compared to wild-type and Pdcd1-knockout cells. This permits improved control of chronic infection without additional immunopathology. Together, these results demonstrate that tuning PD-1 via epigenetic editing can reduce CD8+ T cell dysfunction while avoiding excess immunopathology.

In Vivo CRISPR Screening Reveals CHD7 as a Positive Regulator of Short-lived Effector Cells.

CD8+ T cells differentiate into two subpopulations in response to acute viral infection: memory precursor effector cells (MPECs) and short-lived effector cells (SLECs). MPECs and SLECs are epigenetically distinct; however, the epigenetic regulators required for formation of these subpopulations are mostly unknown. In this study, we performed an in vivo CRISPR screen in murine naive CD8+ T cells to identify the epigenetic regulators required for MPEC and SLEC formation, using the acute lymphocytic choriomeningitis virus Armstrong infection model. We identified the ATP-dependent chromatin remodeler CHD7 (chromodomain-helicase DNA-binding protein 7) as a positive regulator of SLEC formation, as knockout (KO) of Chd7 reduced SLECs numerically. In contrast, KO of Chd7 increased the formation of central memory T cells following pathogen clearance yet attenuated memory cell expansion following a rechallenge. These findings establish CHD7 as a novel positive regulator of SLEC and a negative regulator of central memory T cell formation.

Germline variants in tumor suppressor FBXW7 lead to impaired ubiquitination and a neurodevelopmental syndrome.

Neurodevelopmental disorders are highly heterogenous conditions resulting from abnormalities of brain architecture and/or function. FBXW7 (F-box and WD-repeat-domain-containing 7), a recognized developmental regulator and tumor suppressor, has been shown to regulate cell-cycle progression and cell growth and survival by targeting substrates including CYCLIN E1/2 and NOTCH for degradation via the ubiquitin proteasome system. We used a genotype-first approach and global data-sharing platforms to identify 35 individuals harboring de novo and inherited FBXW7 germline monoallelic chromosomal deletions and nonsense, frameshift, splice-site, and missense variants associated with a neurodevelopmental syndrome. The FBXW7 neurodevelopmental syndrome is distinguished by global developmental delay, borderline to severe intellectual disability, hypotonia, and gastrointestinal issues. Brain imaging detailed variable underlying structural abnormalities affecting the cerebellum, corpus collosum, and white matter. A crystal-structure model of FBXW7 predicted that missense variants were clustered at the substrate-binding surface of the WD40 domain and that these might reduce FBXW7 substrate binding affinity. Expression of recombinant FBXW7 missense variants in cultured cells demonstrated impaired CYCLIN E1 and CYCLIN E2 turnover. Pan-neuronal knockdown of the Drosophila ortholog, archipelago, impaired learning and neuronal function. Collectively, the data presented herein provide compelling evidence of an F-Box protein-related, phenotypically variable neurodevelopmental disorder associated with monoallelic variants in FBXW7.

After Surgically Induced Remission, Ileal and Colonic Mucosa-Associated Microbiota Predicts Crohn's Disease Recurrence.

BACKGROUND & AIMS: Investigating the tissue-associated microbiota after surgically induced remission may help to understand the mechanisms initiating intestinal inflammation in Crohn's disease. METHODS: Patients with Crohn's disease undergoing ileocolic resection were prospectively recruited in 6 academic centers. Biopsy samples from the neoterminal ileum, colon, and rectosigmoid were obtained from colonoscopies performed after surgery. Microbial DNA was extracted for 16S rRNA gene sequencing. Microbial diversity and taxonomic differential relative abundance were analyzed. A random forest model was applied to analyze the performance of clinical and microbial features to predict recurrence. A Rutgeerts score ≥i2 was deemed as endoscopic recurrence. RESULTS: A total of 349 postoperative colonoscopies and 944 biopsy samples from 262 patients with Crohn's disease were analyzed. Ileal inflammation accounted for most of the explained variance of the ileal and colonic mucosa-associated microbiota. Samples obtained from 97 patients who were in surgically induced remission at first postoperative colonoscopy who went on to develop endoscopic recurrence at second colonoscopy showed lower diversity and microbial deviations when compared with patients who remained in endoscopic remission. Depletion of genus Anaerostipes and increase of several genera from class Gammaproteobacteria at the 3 biopsy sites increase the risk of further recurrence. Gut microbiome was able to predict future recurrence better than clinical features. CONCLUSIONS: Ileal and colonic mucosa-associated microbiome deviations precede development of new-onset ileal inflammation after surgically induced remission and show good predictive performance for future recurrence. These findings suggest that targeted microbial modulation is a plausible modality to prevent postoperative Crohn's disease recurrence.

Acute Lymphoblastic Leukemia, Version 2.2024, NCCN Clinical Practice Guidelines in Oncology.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for acute lymphoblastic leukemia (ALL) provide recommendations for management of ALL, with a focus on the classification of ALL subtypes based on immunophenotype and cytogenetic/molecular markers; risk assessment and stratification for risk-adapted therapy; treatment strategies for Philadelphia chromosome (Ph)-positive and Ph-negative ALL for both adolescent and young adult and adult patients; and supportive care considerations. This selection from the NCCN Guidelines for ALL focuses on treatment recommendations for adults with newly diagnosed Ph-negative ALL based on current evidence.

Mediational roles of stress-coping factors in the relationship between patient-perceived communication quality and physical functioning: racial difference between Chinese and Non-Hispanic White American breast cancer survivors.

PURPOSE: The assumption that patient-provider communication may mediate patients' sense of control over cancer to affect health outcomes has limited evidence. This study examines whether patient-perceived cancer care communication quality (PPCQ) mediates stress appraisal and coping behavior, affecting physical functioning across different racial groups. METHODS: Two hundred and twenty Chinese American and 216 non-Hispanic White (NHW) women (ages 28-80) with stage 0-III breast cancer, 1-5 years post-diagnosis, and without recurrence, enrolled and completed a cross-sectional telephone survey. Physical functioning was measured by the NIH-PROMIS short form. Validated measures of PPCQ, patients' evaluation of their socioeconomic well-being, stress appraisal (perceived severity and control), use of coping strategies, treatment-related symptoms, and comorbidities were also assessed. Path analyses were used to examine the mediation for each racial group. RESULTS: Regardless of race, treatment-related symptoms, comorbidities, and socioeconomic well-being were all directly related to physical functioning (p < 0.05). The impact of PPCQ on physical functioning was mediated by perceived control in the Chinese American group (p < 0.05), but not in the NHW group. Perceived severity and coping were not mediators of physical functioning in either group. CONCLUSIONS: The mediational pathway from PPCQ to perceived control to physical functioning in Chinese American survivors may be partially explained by their lower socioeconomic well-being and culturally valued conformity to physicians as a medical authority. These sociocultural dynamics reinforce the importance of cancer care communication. For NHW survivors, the impact of treatment-related symptoms and socioeconomic well-being on physical functioning outweighed their PPCQ and perceived control.

Pilot Trial of Streamlined Genetic Education and Traceback Genetic Testing in Prostate Cancer Survivors.

BACKGROUND: Germline genetic testing is recommended for men with metastatic or high-risk prostate cancer to inform treatment and risk management for other cancers and inform genetic testing in at-risk relatives. However, relatively few patients with prostate cancer undergo genetic testing. Given the low rate of testing and increasing demands on genetic service providers, strategies are needed that reduce barriers to testing while conserving genetic counseling resources. The primary goal of this study was to determine whether a proactive and streamlined "traceback" approach could yield increased genetic testing participation among prostate cancer survivors. METHODS: We randomized 107 survivors of metastatic and high-risk prostate cancer to streamlined testing (ST) versus enhanced usual care (EUC). ST participants were proactively provided with print genetic education materials and the option to proceed to genetic testing without pre-test genetic counseling. EUC participants were sent a letter from their physician advising them of their eligibility for genetic testing and recommending they schedule genetic counseling. The primary outcome was genetic testing participation. Secondary outcomes were distress, knowledge, decision satisfaction, and regret. RESULTS: In the ST group, 41.5% of participants completed genetic testing compared with 27.8% in the EUC group. After adjusting for education and marital status, the odds of testing were more than twice as high for the ST group as for the EUC group (odds ratio, 2.57; 95% CI, 1.05-6.29). The groups did not differ on any of the psychosocial outcomes at the 3-month follow-up. CONCLUSIONS: Proactive outreach paired with streamlined genetic testing delivery may be a safe, effective, and resource-efficient approach to facilitate traceback genetic testing in prostate cancer survivors.

Going the distance in acoustic neuroma resection: microsurgical outcomes at high-volume centers of excellence.

PURPOSE: High-volume hospitals are associated with improved surgical outcomes for acoustic neuromas (ANs). Due to the benign and slow-growing nature of ANs, many patients travel to geographically distant cities, states, or countries for their treatment. However, the impact of travel burden to high-volume centers, as well as its relative benefit are poorly understood. We compared post-operative outcomes between AN patients that underwent treatment at local, low-volume hospitals with those that traveled long distances to high-volume hospitals. METHODS: The National Cancer Database was used to analyze AN patients that underwent surgery (2004-2015). Patients in the lowest quartile of travel distance and volume (Short-travel/Low-Volume: STLV) were compared to patients in the highest quartile of travel distance and volume (Long-travel/High-Volume: LTHV). Only STLV and LTHV cases were included for analysis. RESULTS: Of 13,370 cases, 2,408 met inclusion criteria. STLV patients (n = 1,305) traveled a median of 6 miles (Interquartile range [IQR] 3-9) to low-volume centers (median 2, IQR 1-3 annual cases) and LTHV patients (n = 1,103) traveled a median of 143 miles [IQR 103-230, maximum 4,797] to high-volume centers (median 34, IQR 28-42 annual cases). LTHV patients had lower Charlson/Deyo scores (p = 0.001), mostly received care at academic centers (81.7% vs. 39.4%, p < 0.001), and were less likely to be minorities (7.0% vs. 24.2%, p < 0.001) or underinsured (4.2% vs. 13.8%, p < 0.001). There was no difference in average tumor size. On multivariable analysis, LTHV predicted increased likelihood of gross total resection (odds ratio [OR] 5.6, 95% confidence interval [CI] 3.8-8.4, p < 0.001), longer duration between diagnosis and surgery (OR 1.3, 95% CI 1.0-1.6, p = 0.040), decreased length of hospital stay (OR 0.5, 95% CI 0.4-0.7, p < 0.001), and greater overall survival (Hazard Ratio [HR] 0.6, 95% CI 0.4-0.95, p = 0.029). There was no significant difference in 30-day readmission on adjusted analysis. CONCLUSION: Although traveling farther to high-volume centers was associated with greater time between diagnosis and treatment for AN patients, they experienced superior postoperative outcomes compared to patients who received treatment locally at low-volume centers. Enabling access and travel to high-volume centers may improve AN patient outcomes.

Venetoclax-based salvage therapy for adult patients with relapsed/refractory acute lymphoblastic leukemia.

OBJECTIVES: Dysregulation of BCL-2 family members has been reported in acute lymphocytic leukemia (ALL), with various BH3-dependencies of the leukemic clone. We conducted a multicenter retrospective cohort of patients with relapsed/refractory B or T ALL, with ven-chemotherapy or ven-navitoclax combinations, to assess efficacy and safety. METHODS: Seventeen patients were included in the analysis, median age was 32 years, with 6 B-ALL and 11 T-ALL patients. Nine patients received venetoclax combined with chemotherapy, and 13 patients received venetoclax in combination with navitoclax, vincristine and asparaginase, of which 5 were already exposed to venetoclax in previous lines. RESULTS: ORR was 55% and 46% among the ven-chemotherapy and the ven-navitoclax-chemotherapy, respectively. Most of the responders proceeded to an allogenic bone marrow transplant in both cohorts. The most common adverse effects of the ven-navitoclax combination were infectious complications and hepatotoxicity. CONCLUSIONS: Our data demonstrated the possible efficacy of ven-chemotherapy and ven-navitoclax in r/r ALL with moderate toxicity.

Advancing health equity: A qualitative study assessing barriers and facilitators of implementing hereditary breast and ovarian cancer risk screening tools in community-based organizations.

Genetic counseling and testing (GCT) inform cancer management for persons at risk for hereditary breast and ovarian cancer (HBOC). Community-based organizations (CBOs) may play a role in identifying at-risk Latinx individuals to connect them to GCT but data are lacking. Two academic centers and their four CBO partners planned to implement a validated questionnaire for HBOC risk screening ("HBOC risk screening tool"). This study aimed to assess CBO's preferences for HBOC risk screening tools, as well as the barriers and facilitators anticipated for future implementation. Pre-implementation focus groups were conducted with CBO's staff. Discussions centered on current practices to identify and refer at-risk patients. During the discussion, staff were asked to select one out of five validated HBOC risk screening tools to implement and to discuss anticipated barriers/facilitators for implementation. The four focus groups were coded and qualitative analyzed following the Consolidated Framework for Implementation Research (CFIR) and Health Equity domains. All CBOs chose the Family History Screen 7 (FHS-7). Participants (N = 35) highlighted how the FHS-7 was easy to adapt to better fit the target population and changing guidelines. They had positive attitudes toward implementing the screening tool, stressed how the culture of the organization positioned them to reach the target population, and noted barriers in different CFIR domains (e.g., low knowledge about HBOC and GCT referrals; scarce available resources). Participants pointed to barriers related to health equity domains including limited access to GCT and follow-up care for uninsured and underinsured populations, challenges obtaining accurate family history, and immigration-related barriers. CBOs highlighted the importance of partnering with other stakeholders to overcome barriers. Findings emphasize the need to develop multi-level implementation strategies to overcome barriers and leverage facilitators. This study can inform the development of implementation toolkits for CBOs to implement HBOC screening tools to advance health equity.

An Adaptation, Extension and Pre-Testing of an Interactive Decision Aid for Men Diagnosed with Localized Prostate Cancer in Iceland: A Mixed-Method Study.

In this study an interactive decision aid (DA) for men diagnosed with localized prostate cancer was adapted, extended and pre-tested. The DA's prototype was based on a literature review and other empirically tested DAs. Semi-structured interviews with 12 men (age 65-80) diagnosed with localized prostate cancer were conducted to get feedback on content, usability, and the DA's layout. The interviews were analyzed using thematic analysis and themes were identified using deductive and inductive coding. Participants found the accessibility of the information and the explicit values clarification tool helpful. Four themes were identified: (1) usability and design, (2) content and knowledge, (3) deciding factors of decision-making, and (4) social support. Participants valued receiving extensive and realistic information on surgery/radiation therapy side effects and getting unbiased presentations of treatment options. Following the thematic analysis, the DA was revised and tested in a survey among 11 newly diagnosed prostate cancer patients (age 60-74). The participants valued the DA and found it helpful when making a treatment decision, and all reported that they would recommend it to others making a prostate cancer treatment decision. The DA is currently being tested in a randomized clinical trial (RCT). This is the first DA developed for prostate cancer patients in Iceland and if the results of the RCT show that it is more effective than standard care in assisting newly diagnosed patients with their treatment decision, the DA can be easily translated and adapted to cultures similar to Iceland such as the Nordic countries.

Using Protection Motivation Theory to Predict Intentions for Breast Cancer Risk Management: Intervention Mechanisms from a Randomized Controlled Trial.

The purpose of this study is to evaluate the direct and indirect effects of a web-based, Protection Motivation Theory (PMT)-informed breast cancer education and decision support tool on intentions for risk-reducing medication and breast MRI among high-risk women. Women with ≥ 1.67% 5-year breast cancer risk (N = 995) were randomized to (1) control or (2) the PMT-informed intervention. Six weeks post-intervention, 924 (93% retention) self-reported PMT constructs and behavioral intentions. Bootstrapped mediations evaluated the direct effect of the intervention on behavioral intentions and the mediating role of PMT constructs. There was no direct intervention effect on intentions for risk-reducing medication or MRI (p's ≥ 0.12). There were significant indirect effects on risk-reducing medication intentions via perceived risk, self-efficacy, and response efficacy, and on MRI intentions via perceived risk and response efficacy (p's ≤ 0.04). The PMT-informed intervention effected behavioral intentions via perceived breast cancer risk, self-efficacy, and response efficacy. Future research should extend these findings from intentions to behavior. ClinicalTrials.gov Identifier: NCT03029286 (date of registration: January 24, 2017).

Prospective Evaluation of Coronavirus Disease 2019 (COVID-19) Vaccine Responses Across a Broad Spectrum of Immunocompromising Conditions: the COVID-19 Vaccination in the Immunocompromised Study (COVICS).

BACKGROUND: We studied humoral responses after coronavirus disease 2019 (COVID-19) vaccination across varying causes of immunodeficiency. METHODS: Prospective study of fully vaccinated immunocompromised adults (solid organ transplant [SOT], hematologic malignancy, solid cancers, autoimmune conditions, human immunodeficiency virus [HIV]) versus nonimmunocompromised healthcare workers (HCWs). The primary outcome was the proportion with a reactive test (seropositive) for immunoglobulin G to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain. Secondary outcomes were comparisons of antibody levels and their correlation with pseudovirus neutralization titers. Stepwise logistic regression was used to identify factors associated with seropositivity. RESULTS: A total of 1271 participants enrolled: 1099 immunocompromised and 172 HCW. Compared with HCW (92.4% seropositive), seropositivity was lower among participants with SOT (30.7%), hematological malignancies (50.0%), autoimmune conditions (79.1%), solid tumors (78.7%), and HIV (79.8%) (P < .01). Factors associated with poor seropositivity included age, greater immunosuppression, time since vaccination, anti-CD20 monoclonal antibodies, and vaccination with BNT162b2 (Pfizer) or adenovirus vector vaccines versus messenger RNA (mRNA)-1273 (Moderna). mRNA-1273 was associated with higher antibody levels than BNT162b2 or adenovirus vector vaccines after adjusting for time since vaccination, age, and underlying condition. Antibody levels were strongly correlated with pseudovirus neutralization titers (Spearman r = 0.89, P < .0001), but in seropositive participants with intermediate antibody levels, neutralization titers were significantly lower in immunocompromised individuals versus HCW. CONCLUSIONS: Antibody responses to COVID-19 vaccines were lowest among SOT and anti-CD20 monoclonal recipients, and recipients of vaccines other than mRNA-1273. Among those with intermediate antibody levels, pseudovirus neutralization titers were lower in immunocompromised patients than HCWs. Additional SARS-CoV-2 preventive approaches are needed for immunocompromised persons, which may need to be tailored to the cause of immunodeficiency.

Psychosocial impact of proactive rapid genetic counseling following breast cancer diagnosis.

OBJECTIVE: As germline genetic referral becomes increasingly routine as part of the care of newly diagnosed breast cancer patients, it is important to understand the psychosocial impact of genetic counseling at the time of diagnosis. We examined the psychosocial and quality of life (QOL) impact of providing proactive rapid genetic counseling and testing (RGCT) in the immediate aftermath of a breast cancer diagnosis. METHODS: We randomized 330 patients in a 2:1 ratio to proactive rapid genetic counseling (RGCT; N = 222) versus usual care (UC; N = 108). Participants completed a baseline telephone survey before randomization and definitive surgery and a follow-up survey at 1-month post-randomization. We evaluated the impact of RGCT versus UC on breast cancer genetic knowledge, distress, QOL, and decisional conflict. Given that 43% of UC participants and 86% of RGCT participants completed genetic counseling prior to the 1-month assessment, we also evaluated the impact of genetic counseling participation over and above group assignment. RESULTS: The RGCT intervention led to increased breast cancer genetic knowledge relative to UC but did not differentially impact other study outcomes. Across groups patients who participated in genetic counseling had significantly increased knowledge and improved QOL compared to those who did not participate in genetic counseling. CONCLUSIONS: While prior research has documented the impact of genetic counseling and testing on surgical decisions, these results confirm that participation in genetic counseling at the time of diagnosis can yield improvements in knowledge and QOL in the short-term.

Tofacitinib inhibits inflammatory cytokines from ulcerative colitis and healthy mucosal explants and is associated with pSTAT1/3 reduction in T-cells.

Poor translatability of animal disease models has hampered the development of new inflammatory bowel disorder (IBD) therapeutics. We describe a preclinical, ex vivo system using freshly obtained and well-characterized human colorectal tissue from patients with ulcerative colitis (UC) and healthy control (HC) participants to test potential therapeutics for efficacy and target engagement, using the JAK/STAT inhibitor tofacitinib (TOFA) as a model therapeutic. Colorectal biopsies from HC participants and patients with UC were cultured and stimulated with multiple mitogens ± TOFA. Soluble biomarkers were detected using a 29-analyte multiplex ELISA. Target engagement in CD3+CD4+ and CD3+CD8+ T-cells was determined by flow cytometry in peripheral blood mononuclear cells (PBMCs) and isolated mucosal mononuclear cells (MMCs) following the activation of STAT1/3 phosphorylation. Data were analyzed using linear mixed-effects modeling, t test, and analysis of variance. Biomarker selection was performed using penalized and Bayesian logistic regression modeling, with results visualized using uniform manifold approximation and projection. Under baseline conditions, 27 of 29 biomarkers from patients with UC were increased versus HC participants. Explant stimulation increased biomarker release magnitude, expanding the dynamic range for efficacy and target engagement studies. Logistic regression analyses identified the most representative UC baseline and stimulated biomarkers. TOFA inhibited biomarkers dependent on JAK/STAT signaling. STAT1/3 phosphorylation in T-cells revealed compartmental differences between PBMCs and MMCs. Immunogen stimulation increases biomarker release in similar patterns for HC participants and patients with UC, while enhancing the dynamic range for pharmacological effects. This work demonstrates the power of ex vivo human colorectal tissue as preclinical tools for evaluating target engagement and downstream effects of new IBD therapeutic agents.NEW & NOTEWORTHY Using colorectal biopsy material from healthy volunteers and patients with clinically defined IBD supports translational research by informing the evaluation of therapeutic efficacy and target engagement for the development of new therapeutic entities. Combining experimental readouts from intact and dissociated tissue enhances our understanding of the tissue-resident immune system that contribute to disease pathology. Bayesian logistic regression modeling is an effective tool for predicting ex vivo explant biomarker release patterns.

Process evaluation of a culturally targeted video for Latinas at risk of hereditary breast and ovarian cancer.

This paper presents a process evaluation of a culturally targeted narrative video about hereditary breast and ovarian cancer (HBOC) for Latina women at risk for HBOC. Spanish-speaking Latina women at risk for HBOC participated in a single arm study (n = 40). Participants watched the video developed by the authors and responded to surveys. We used mixed methods to assess theoretical constructs that are hypothesized mediators of narrative interventions (i.e., transportation or engagement, identification with characters, emotions) and implementation outcomes (e.g., acceptability). Descriptive statistics summarized theoretical constructs and implementation outcomes. We conducted Mann-Whitney U tests to assess the differences in theoretical and implementation outcomes between participants who were affected versus. unaffected and participants with different levels of education and health literacy. We used the consensual qualitative research framework to analyze qualitative data. Participants' mean age was 47.1 years (SD = 9.48). Most participants were high school graduates or less (62.5%). Acceptability of the video was extremely high (Md = 10.0, IQR = 0.2, scale 1-10). Most (82.5%) suggested video dissemination be through social media. Participants were highly engaged (Md = 5.7, IQR = 1.5, scale 1-7), strongly identified with the main character (Md = 8.7, IQR = 2.6, scale 1-10), and reported experiencing mostly positive emotions (Md = 9.5, IQR = 2.8, scale 1-10). Participants with low health literacy and affected participants reported a significantly higher identification with the main character (p<.05). Qualitative data reinforced the quantitative findings. Women reported gaining knowledge, correcting misconceptions, and feeling empowered. Our culturally targeted video is highly acceptable and targets mechanisms of behavior change for narrative interventions. The video is easily disseminable and can be used as an education tool for patients including affected and unaffected women and patients with different education and health literacy levels. Future studies should test the impact of the video in enhancing genetic counseling and testing uptake.

The Genetic Education for Men (GEM) Trial: Development of Web-Based Education for Untested Men in BRCA1/2-Positive Families.

Cascade testing for hereditary breast/ovarian cancer is an important public health priority. Increasing attention has been paid to the relevance of testing for men within BRCA1/2-positive families given that such testing may provide important information about their cancer risks, particularly for prostate cancer, and risks to their offspring. However, men are much less likely to seek genetic counseling and testing than their at-risk female relatives. To facilitate access to pre-test information and testing, we developed a web-based intervention (WI) for men that we are evaluating in a pilot randomized controlled trial (RCT). This paper describes three phases of research in the development of the WI: (1) formative (qualitative) research among men from BRCA1/2 families to assess needs and preferences for education; (2) a detailed description of the organization, format, and content of the WI; and (3) usability testing. We discuss the aims and hypotheses of the pilot RCT in which the WI is being compared with an enhanced usual care condition among at-risk men. We expect that the WI described here will foster informed decisions and lead to increased use of BRCA1/2 counseling and testing, potentially yielding improved cancer control outcomes for this understudied group, and for their at-risk relatives.

Voices of the students: Adolescent well-being and social interactions during the emergent shift to online learning environments.

Health and safety concerns during the COVID-19 pandemic required many face-to-face United States schools to suddenly shut their doors, moving classes to virtual learning environments. Amidst concerns of technology overuse, adolescents across the country saw dramatic increases in both personal screen time use and social isolation as they learned to navigate online schooling. Understanding the impact of the pandemic-related shutdowns upon adolescent well-being, learning, and social life is critical for designing effective online learning experiences, but research provides few insights from the adolescent perspective. This mixed methods study works to fill this gap by investigating adolescent needs and perceptions during the pandemic. The main questions asked are:To what extent does adolescent well-being during the pandemic differ from pre-pandemic well-being?What factors do adolescents view as influences upon their learning during the imposed shift to online schooling?What social changes and concerns do adolescents report during the pandemic? Twenty-one adolescents completed Likert scale surveys and participated in semi-structured one-to-one interviews. Results showed a significant decrease in positive affect and a significant increase in negative affect during the pandemic, suggesting a decline in well-being. The majority of participants reported high distractibility and noted the lure of entertaining technology, but also described their smartphones as "connecting" and "necessary". Social interactions were a priority for all participants, but participants agreed that opportunities for social connectedness in online education were limited. The challenges of online learning, the importance of identifying and responding to student needs, and suggested strategies for online education are discussed.

Prior breast density awareness, knowledge, and communication in a health system-embedded behavioral intervention trial.

BACKGROUND: Breast density is an important breast cancer risk factor and a focus of recent national and state health policy efforts. This article describes breast density awareness, knowledge, and communication among participants in a health system-embedded trial with clinically elevated breast cancer risk 1 year before state-mandated density disclosure. METHODS: Trial participants' demographics and prior health history were ascertained from electronic health records. The proportions of women reporting prior breast density awareness, knowledge of density's masking effect, and communication with a provider about their own breast density were calculated using baseline interview data collected from 2017 to 2018. Multiple logistic regression was used to estimate associations between women's characteristics and density awareness, knowledge, and communication. RESULTS: Although the overwhelming majority of participants had heard of breast density (91%) and were aware of breast density's masking effect (87%), only 60% had ever discussed their breast density with a provider. Annual mammography screening was associated with prior breast density awareness (odds ratio [OR], 2.97; 95% confidence interval [CI], 1.29-6.81), knowledge (OR, 2.83; 95% CI, 1.20-6.66), and communication (OR, 2.87; 95% CI, 1.34-6.16) compared with an infrequent or unknown screening interval. Receipt of breast biopsy was also associated with prior knowledge (OR, 1.60; 95% CI, 1.04-2.45) and communication (OR, 1.36; 95% CI, 1.00-1.85). CONCLUSIONS: Breast density awareness and knowledge are high among insured women participating in clinical research, even in the absence of mandated density disclosure. Patient-provider communication about personal density status is less common, particularly among women with fewer interactions with breast health specialists.

Complete Resolution of Mucosal Neutrophils Associates With Improved Long-Term Clinical Outcomes of Patients With Ulcerative Colitis.

BACKGROUND & AIMS: We investigated correlations between histologic features of the colonic mucosa in patients with ulcerative colitis (UC) and clinical outcomes during a 3-year follow-up period. METHODS: We obtained baseline biopsies from all colorectal segments (n = 889) from 281 patients with UC enrolled in a prospective study at a single center from 2009 through 2013. Biopsies were assessed in a blinded manner using validated histologic scoring systems (the Geboes score, Nancy histopathologic index, and Robarts histopathologic index). Clinical, endoscopic, and histologic data were collected and tested for correlations with systemic corticosteroid use, hospitalization, and colectomy within 3 years of the index colonoscopy. RESULTS: We found histologic evidence of UC activity (Geboes score ≥ 2B.1) in biopsies from 182 patients (65%) and endoscopic evidence of UC activity in 149 patients (53%) (substantial agreement, κ = 0.60). Histologic features of UC activity were associated with increased rates of systemic corticosteroid use, colectomy, and hospitalization in the entire cohort (P < .05 for all) and associated with increased rates of systemic corticosteroid use in an analysis limited to patients in endoscopic remission (P < .001). In patients in endoscopic remission, only histologic activity was independently associated with use of systemic corticosteroids (multivariate odds ratio, 6.34; 95% CI, 2.20-18.28; P = .001). Similar results were seen when the entire cohort was analyzed. Compared with patients without histologic evidence of UC activity, patients with only a small number of mucosal neutrophils still had higher rates of systemic corticosteroid use (P < .001). CONCLUSIONS: Histologic evidence of UC activity, including small numbers of neutrophils in the colonic mucosa, is the only factor independently associated with use of systemic corticosteroids. Complete resolution of neutrophil-associated inflammation should be a target for treatment of UC.
