ABSTRACT

INTRODUCTION: Identifying responsive outcome measures for assessing functional change related to cognition, communication, and quality of life for individuals with neurodegenerative disease is important for intervention design and clinical care. Goal Attainment Scaling (GAS) has been used as an outcome measure to formally develop and systematically measure incremental progress toward functional, patient-centered goals in clinical settings. Evidence suggests that GAS is reliable and feasible for use in older adult populations and in adult populations with cognitive impairment, but no review has assessed the suitability of GAS in older adults with neurodegenerative disease experiencing dementia or cognitive impairment, based on responsiveness. This study conducted a systematic review to evaluate the suitability of GAS as an outcome measure for older adult populations with neurodegenerative disease experiencing dementia or cognitive impairment, based on responsiveness. METHODS: The review was registered with PROSPERO and performed by searching ten electronic scientific databases (PubMed, Medline OVID, CINAHL, Cochrane, Embase, Web of Science, PsycINFO, Scopus, OTSeeker, REHABDATA) and four registries (Clinicaltrials.gov, Grey Literature Report, Mednar, OpenGrey). A summary measure of responsiveness (post-intervention minus pre-intervention mean GAS T-score) was compared across eligible studies using a random-effects meta-analysis. Risk of bias in included studies was assessed using the NIH Quality Assessment Tool for Before-After (Pre-Post) Studies with No Control Group. RESULTS: 882 eligible articles were identified and screened by two independent reviewers. Ten studies met inclusion criteria for the final analysis. Of the ten included reports, 3 focus on all-cause dementia, 3 on multiple sclerosis, 1 on Parkinson's disease, 1 on mild cognitive impairment, 1 on Alzheimer's disease, and 1 on primary progressive aphasia. Responsiveness analyses showed pre- and post-intervention GAS goals were significantly different from zero (Z = 7.48, p < 0.001), with post-intervention GAS scores being higher than pre-intervention GAS scores. Three included studies showed a high risk of bias, 3 showed a moderate risk of bias, and 4 showed a low risk of bias. Overall risk of bias of included studies was rated as moderate. CONCLUSION: GAS showed an improvement in goal attainment across different dementia patient populations and intervention types. The overall moderate risk of bias suggests that while bias is present across included studies (e.g., small sample size, unblinded assessors), the observed effect likely represents the true effect. This suggests that GAS is responsive to functional change and may be suitable for use in older adult populations with neurodegenerative disease experiencing dementia or cognitive impairment.

ABSTRACT

PURPOSE: Primary progressive aphasia (PPA) is a clinical neurodegenerative dementia syndrome characterized by early, selective, and progressive language impairment. PPA onset is gradual, providing time to potentially identify additional or alternative expressive communication modes; however, reports of communication mode use and effectiveness by persons with PPA have not been described. This study characterized the use, frequency, and perceived effectiveness of communication modes reported by individuals with PPA. METHOD: Forty-one participants with mild-to-moderate PPA completed a structured interview detailing the type, frequency, and perceived effectiveness of 12 potential communication modes, categorized by technology required (no-tech, low-tech, and high-tech). The ratio of modes used was compared across technology categories with a repeated-measures generalized linear model assuming a binomial distribution with an overall Wald chi-square statistic, followed by pairwise post hoc t-test comparisons. RESULTS: Of the 12 communication modes assessed, participants reported using a median of eight (range: 5-10). All participants affirmed using speech, facial expressions, and talking on the phone. Frequency and perceived effectiveness ratings for these three modes were endorsed at the "some/most of the time" level for more than 80% of the participants. No-tech mode use was significantly higher than reported high-tech and low-tech modes (p = .004 and p < .0001, respectively). Even so, while some high-tech modes (apps) and some low-tech modes (nonelectronic augmentative and alternative communication) had fewer users, effectiveness ratings were moderate to high for all but one user. CONCLUSIONS: Persons with mild-to-moderate language impairment due to PPA report using a range of communication modes with moderate-to-high frequency and perceived effectiveness. These outcomes provide practical information when considering mode refinement or expansion during intervention to maximize communication participation. Barriers to modality use may include low awareness or access, which could be queried by future studies and supported by speech and language interventions.

ABSTRACT

Introduction: Angiotensinogen (AOG) is the precursor of peptides of the renin angiotensin system (RAS). Because insulin up-regulates transcriptional factors that normally repress kidney AOG synthesis, we evaluated urinary AOG (uAOG) in patients with type 1 diabetes (T1D) and microalbuminuria who are receiving either intensive or conventional insulin therapy. Methods: Urine samples from participants of the Diabetes Control and Complications Trial (DCCT) were used for the following: (i) uAOG/creatinine measurements in 103 patients with microalbuminuria and 103 patients with normoalbuminuria, matched for age, gender, disease duration, and allocation to insulin therapy; and (ii) uAOG/creatinine measurements from patients with microalbuminuria allocated to intensive insulin therapy (n = 58) or conventional insulin therapy (n = 41) after 3 years on each modality. Results: uAOG was higher in patients who started with microalbuminuria than in those with normoalbuminuria (6.65 vs. 4.0 ng/mg creatinine, P < 0.01). uAOG was higher in females than in males with microalbuminuria (11.7 vs. 5.4 ng/mg creatinine, P = 0.015). uAOG was lower in patients with microalbuminuria allocated to intensive insulin therapy than in conventional insulin therapy (3.98 vs. 7.42 ng/mg creatinine, P < 0.01). These differences in uAOG were observed though albumin excretion rate (AER) was not significantly different. Conclusion: In patients with T1D and microalbuminuria, uAOG is increased and varies with gender and the type of insulin therapy independently of AER. This suggests that AOG production is increased in females and it is decreased by intensive insulin therapy. The reduction in uAOG with intensive insulin therapy, by kidney RAS downregulation, may contribute to the known renoprotective action associated with intensive insulin and improved glycemic control.

ABSTRACT

Engaging in multiple health risk behaviors simultaneously may increase the risk for cardiometabolic diseases. This study examined the prevalence and clustering of three health behaviors (physical activity, fruit and vegetable consumption, and smoking) among Latino men. The participants were 99 Mexican and 104 Puerto Rican men who participated in a study addressing culture- and obesity-related factors. The health behaviors were obtained from self-reported and anthropometric assessments through objective measurements. Among all participants, 5% had no health risk behaviors, 30% had one, 47% had two, and 18% had all three; their most common health risk behavior cluster was low physical activity and low fruit and vegetable consumption (28%). Among Puerto Rican men, 7% had no health risk behaviors, 24% had one, 51% had two, and 18% had all three; their most common health risk behavior cluster was current smoker and low fruit and vegetable consumption (28%). Among Mexican men, 3% had no health risk behaviors, 36% had one, 43% had two and 19% had all three; their most common health risk behavior cluster was low physical activity and low fruit and vegetable consumption (33%). The findings highlight the need for lifestyle interventions that target multiple health risk behaviors related to cardiometabolic diseases in Latinos.

ABSTRACT

This study examined the logistical, practical, and cultural preferences of Latinos regarding the design of a healthy eating, physical activity, and body image intervention. Puerto Rican and Mexican men (n = 203) completed an interview as part of an NIH-funded study. Overall, 66.5% preferred the intervention to be in Spanish only or both Spanish and English; 88.67% said it was moderately, very or extremely important for the intervention leader to be bilingual; and 66.01% considered it moderately to extremely important for the leader to be Hispanic or Latino. Most participants (83.74%) reported they would be willing to attend an intervention that met twice per week and 74.38% said they would be willing to attend an intervention that met for 1.5 to 2 h, twice weekly. Overall, the majority said they would be moderately to extremely interested in attending an exercise program if it consisted of aerobics with Latin or salsa movements (74.88%) and if it consisted of aerobics with Latin or salsa music (70.44%). Some participants were moderately to extremely interested in attending an intervention if it included dichos (Latino sayings) (65.02%) and cuentos (folktales or stories) (69.46%). The findings have implications for lifestyle and body image interventions aimed at preventing cardiometabolic diseases.

ABSTRACT

BACKGROUND: Primary progressive aphasia (PPA) is a clinical dementia syndrome. Impairments in language (speaking, reading, writing, and understanding) are the primary and persistent symptoms. These impairments progress insidiously and devastate communication confidence, participation, and quality of life for persons living with PPA. Currently, there are no effective disease modifying treatments for PPA. Speech-language interventions hold promise for mitigating communication challenges and language symptoms. However, evidence regarding their efficacy in PPA is of low quality and there are currently no rigorous randomized trials. METHOD: Communication Bridge™-2 (CB2) is a Stage 2, superiority, single-blind, randomized, parallel group, active-control, behavioral clinical trial delivered virtually within a telehealth service delivery model to individuals with PPA. Ninety carefully characterized participants with clinically confirmed PPA will be randomized to one of two speech-language intervention arms: (1) Communication Bridge™ a dyadic intervention based in communication participation therapy models that incorporates salient training stimuli or (2) the control intervention a non-dyadic intervention based in impairment therapy models addressing word retrieval and language production that incorporates fixed stimuli. The superiority of Communication Bridge™ over the Control arm will be evaluated using primary outcomes of communication confidence and participation. Other outcomes include accuracy for trained words and scripts. Participants complete two therapy blocks over a 12-month period. Outcomes will be measured at baseline, at each therapy block, and at 12 months post enrollment. DISCUSSION: The CB2 trial will supply Level 2 evidence regarding the efficacy of the Communication Bridge™ intervention delivered in a telehealth service delivery model for individuals with mild to moderate PPA. An important by-product of the CB2 trial is that these data can be used to evaluate the efficacy of speech-language interventions delivered in both trial arms for persons with PPA. The impact of these data should not be overlooked as they will yield important insights examining why interventions work and for whom, which will advance effectiveness trials for speech-language interventions in PPA. TRIAL REGISTRATION: ClinicalTrials.gov NCT03371706 . Registered prospectively on December 13, 2017.

ABSTRACT

Triple-negative/basal-like breast cancer (BC) is characterized by aggressive biological features, which allow relapse and metastatic spread to occur more frequently than in hormone receptor-positive (luminal) subtypes. The molecular complexity of triple-negative/basal-like BC poses major challenges for the implementation of targeted therapies, and chemotherapy remains the standard approach at all stages. The matricellular protein cysteine-rich angiogenic inducer 61 (CCN1/CYR61) is associated with aggressive metastatic phenotypes and poor prognosis in BC, but it is unclear whether anti-CCN1 approaches can be successfully applied in triple-negative/basal-like BC. Herein, we first characterized the prevalence of CNN1 expression in matched samples of primary tumors and metastatic relapse in a series of patients with BC. We then investigated the biological effect of CCN1 depletion on tumorigenic traits in vitro and in vivo using archetypal TNBC cell lines. Immunohistochemical analyses of tissue microarrays revealed a significant increase of the highest CCN1 score in recurrent tissues of triple-negative/basal-like BC tumors. Stable silencing of CCN1 in triple-negative/basal-like BC cells promoted a marked reduction in the expression of the CCN1 integrin receptor αvß3, inhibited anchorage-dependent cell growth, reduced clonogenicity, and impaired migration capacity. In an orthotopic model of triple-negative/basal-like BC, silencing of CCN1 notably reduced tumor burden, which was accompanied by decreased microvessel density and concurrent induction of the luminal epithelial marker E-cadherin. Thus, CNN1/CYR61-targeting strategies might have therapeutic value in suppressing the biological aggressiveness of triple-negative/basal-like BC.

ABSTRACT

OBJECTIVE: To compare outcomes of obese and nonobese pediatric patients with acute promyelocytic leukemia (APL) from the Cancer and Leukemia Group B trial (CALGB) 9710 and the Children's Oncology Group trial AAML0631. METHODS: Data including demographics, adverse events, overall and event-free survival (EFS) were analyzed. RESULTS: The prevalence of obesity was 34% on C9710 and 35% on AAML0631. There was significantly lower overall and EFS in the obese population on multivariable analysis on AAML0631 but not on CALGB 9710. Eleven patients died during therapy or in follow-up. CONCLUSION: The prevalence of obesity is higher in pediatric patients with APL compared to the general population. The decreased EFS and OS in obese patients on AAML0631 suggest that the presence of obesity can influence outcomes using the most current treatment. These findings support the need for further research on the potential role of obesity in pediatric APL leukemogenesis.

ABSTRACT

PURPOSE: The use of telepractice in the field of communication disorders offers an opportunity to provide care for those with primary progressive aphasia (PPA). The Western Aphasia Battery-Revised (WAB-R) is used for differential diagnosis, to assess severity of aphasia, and to identify a language profile of strengths and challenges. Telehealth administration of the WAB-R is supported for those with chronic aphasia due to stroke but has not yet been systematically explored in neurodegenerative dementia syndromes. To fill this gap, in-person and telehealth performance on the WAB-R from participants with mild to moderate PPA was compared. METHOD: Nineteen participants with mild to moderate PPA were administered the WAB-R in person and over videoconferencing. Videoconferencing administration included modifications to the testing protocol to ensure smooth completion of the assessment. Subtest and Aphasia Quotient (WAB-AQ) summary scores were compared using concordance coefficients to measure the relationship between the administration modes. RESULTS: In-person and telehealth scores showed strong concordance for the WAB-AQ, Auditory Verbal Comprehension subtest, and Naming & Word Finding subtest. The Spontaneous Speech test summary score had slightly lower concordance, indicating the need for caution when comparing these scores across administration modes. CONCLUSION: These findings support extending the use of telehealth administration of the WAB-R via videoconferencing to those with mild to moderate PPA given appropriate modifications to testing protocol.

ABSTRACT

OBJECTIVES: Previous reports established the feasibility of a telehealth model for delivering speech-language therapy via Internet videoconferencing, which connects individuals with primary progressive aphasia (PPA) to an expert speech and language pathologist for treatment. This study reports feasibility of the same telehealth intervention in a larger set of progressive aphasia participants and explores factors potentially influencing functional intervention outcomes. METHODS: Participants with PPA or progressive aphasia in the context of a neurodegenerative dementia syndrome and their communication partners were enrolled into an 8-session intervention, with 3 evaluations (baseline, 2 months, and 6 months postenrollment). Half of the participants were randomized into a "check-in" group and received 3-monthly half-hour sessions postintervention. Mixed linear models with post hoc testing and percent change in area under the curve were used to examine communication confidence over time, as well as the influence of check-in sessions and the role of communication partner engagement on communication confidence. RESULTS: Communication confidence improved at the 2-month evaluation and showed no significant decline at the 6-month evaluation. Item-level analysis revealed gains in communication confidence across multiple communication contexts. Gains and maintenance of communication confidence were only present for the engaged communication partner group and were not bolstered by randomization to the check-in group. DISCUSSION: Internet-based, person-centered interventions demonstrate promise as a model for delivering speech-language therapy to individuals living with PPA. Maintenance is possible for at least 6 months postenrollment and is better for those with engaged communication partners, which supports the use of dyadic interventions.

ABSTRACT

PURPOSE: Angiosarcomas represents a diverse group of aggressive high-grade vascular tumours with limited therapeutic options. We sought to determine the safety and efficacy of regorafenib, a small-molecule multikinase inhibitor, in the treatment of metastatic or locally advanced unresectable angiosarcoma. PATIENTS AND METHODS: In this single-arm multicentre, open-label phase II clinical trial, 31 patients were enrolled and received regorafenib 160 mg PO daily for 21 days of a 28-day cycle. The primary endpoint for the study was progression-free survival at 4 months. Secondary endpoints included overall survival, response rate, and safety. Patients (≥18 years) with an Eastern Cooperative Oncology Group (ECOG) score of 0-1, a life expectancy of at least 4 months who had progressed on at least one but no more than 4 prior lines of therapy were eligible. RESULTS: Of the 23 patients evaluable for efficacy, 2 had a complete response (8.7%), and 2 had a partial response (8.7%), for a total overall response rate of 17.4%. Median PFS was 5.5 months, and 12/23 patients (52.2%) had a PFS of greater than 4 months. 10/31 (32.3%) patients evaluable for toxicity had a grade 3 or higher adverse events. CONCLUSIONS: Regorafenib is a safe and active treatment for refractory metastatic and unresectable angiosarcoma. Rates of adverse events were comparable to prior studies of regorafenib for other tumour types. Regorafenib, the single agent, could be considered as therapy for patients with metastatic or unresectable AS.

ABSTRACT

PURPOSE: To evaluate the effect of the anatomic size on 3D radiomic imaging features of the breast cancer hepatic metastases. MATERIALS AND METHODS: CT scans of 81 liver metastases from 54 patients with breast cancer were evaluated. Ten most common 3D radiomic features from the histogram and gray level co-occurrence matrix (GLCM) categories were calculated for the hepatic metastases (HM) and compared to normal liver (NL). The effect of size was evaluated by using linear mixed-effects regression models. The effect of size on different radiomic features was analyzed for both liver lesions and background liver. RESULTS: Three-dimensional radiomic features from GLCM demonstrate an important size dependence. The texture-feature size dependence was found to be different among feature categories and between the HM and NL, thus demonstrating a discriminatory power for the tissue type. Significant difference in the slope was found for GLCM homogeneity (NL slope = 0.004, slope difference 95% confidence interval [CI] 0.06-0.1, p <0.001), contrast (NL slope = 45, slope difference 95% CI 205-305, p <0.001), correlation (NL slope = 0.04, slope difference 95% CI 0.11-0.21, p <0.001), and dissimilarity (NL slope = 0.7, slope difference 95% CI 3.6-5.4, p <0.001). The GLCM energy (NL slope = 0.002, slope difference 95% CI -0.0005 to -0.0003, p <0.007), and entropy (NL slope = 1.49, slope difference 95% CI 0.07-0.52, p <0.009) exhibited size-dependence for both NL and HM, although demonstrating a difference in the slope between themselves. CONCLUSION: Radiomic features of breast cancer hepatic metastasis exhibited significant correlation with tumor size. This finding demonstrates the complex behavior of imaging features and the need to include feature-specific properties into radiomic models.

ABSTRACT

BACKGROUND: Lymphopenia has been associated with inferior cancer outcomes, but there is limited data in breast cancer. We describe the effects of neoadjuvant chemotherapy on circulating immune cells and its association with pathological complete response (pCR) rates in triple negative breast cancer (TNBC). METHODS: We constructed a database of patients with early stage TNBC treated with neoadjuvant chemotherapy. Circulating lymphocytes and monocytes were assessed before and after neoadjuvant chemotherapy. These were correlated with pCR rates and disease-free survival (DFS) using Fisher's exact test, logistic regression, and the log-rank test. RESULTS: From 2000 to 2015, we identified 95 eligible patients. Median age was 50; 29 (31%) were treated with platinum-containing chemotherapy; and 66 (69%) with nonplatinum-containing chemotherapy (anthracycline-taxane, or either alone). About 32 (34%) patients achieved a pCR; and 33 (35%) had recurrence events. Median follow-up time was 47 months. No significant associations were found between changes in lymphocytes and pCR or DFS. There was a correlation between lower monocyte levels after neoadjuvant chemotherapy and pCR (mean monocyte 0.56 in those with no-pCR vs 0.46 in those with pCR, P = .049, multivariate P = .078) and DFS (median DFS in highest monocyte quartile was 30 vs 107 months in lowest quartile, P = .022, multivariate P = .023). In patients who received nonplatinum regimens, DFS was better among those who had larger decreases in monocytes. CONCLUSIONS: Development of lymphopenia from neoadjuvant chemotherapy was not associated with pCR in patients with TNBC. However, lower absolute circulating monocytes after neoadjuvant chemotherapy was associated with improved outcomes.

ABSTRACT

ABSTRACT: Clinical health outcomes and health disparities can be improved through interprofessional collaborations among multidisciplinary clinicians, health care services researchers, and patients. Bridging gaps between community clinics and urban academic centers allows added valuable perspectives that can lead to improved care and extend clinical research. Nurse practitioners (NPs) who serve as primary care providers in many rural community clinics can facilitate access to clinical trials for patients who are rarely included in health care services research as well as coordinate interprofessional research team collaboration. A NP working in a rural clinic can assist academic-based research teams in designing feasible strategies to address disparities and improve health care of underserved populations. The purpose of this article was to provide an example of a rural provider/urban academic research team collaborating to conduct a health literacy-directed randomized controlled trial to improve colorectal cancer screening in isolated rural community clinics.

ABSTRACT

BACKGROUND: Response rates to single agent immune checkpoint blockade in unselected pretreated HER2-negative metastatic breast cancer (MBC) are low. However, they may be augmented when combined with chemotherapy. METHODS: We conducted a single-arm, phase II study of patients with triple negative (TN) or hormone receptor-positive endocrine-refractory (HR+) MBC who were candidates for capecitabine. Patients were treated with pembrolizumab 200 mg intravenously day 1 and capecitabine 1000 mg/m2 by mouth twice daily on days 1-14 of a 21-day cycle. The primary end point was median progression-free survival (mPFS) compared with historic controls and secondary end points were overall response rate (ORR), safety and tolerability. The study had 80% power to detect a 2-month improvement in mPFS with the addition of pembrolizumab over historic controls treated with capecitabine alone. RESULTS: Thirty patients, 16 TN and 14 HR+ MBC, were enrolled from 2017 to 2018. Patients had a median age of 51 years and received a median of 1 (range 0-6) prior lines of therapy for MBC. Of 29 evaluable patients, the mPFS was 4.0 (95% CI 2.0 to 6.4) months and was not significantly longer than historic controls of 3 months. The median overall survival was 15.4 (95% CI 8.2 to 20.3) months. The ORR was 14% (n=4), stable disease (SD) was 41% (n=12) and clinical benefit rate (CBR=partial response+SD>6 months) was 28% (n=8). The ORR and CBR were not significantly different between disease subtypes (ORR 13% and 14%, CBR 25% and 29% for TN and HR+, respectively). The 1-year PFS rate was 20.7% and three patients have ongoing responses. The most common adverse events were low grade and consistent with those seen in MBC patients receiving capecitabine, including hand-foot syndrome, gastrointestinal symptoms, fatigue and cytopenias. Toxicities at least possibly from pembrolizumab included grade 3 or 4 liver test abnormalities (7%), rash (7%) and diarrhea (3%), as well as grade 5 hepatic failure in a patient with liver metastases. CONCLUSIONS: Compared with historical controls, pembrolizumab with capecitabine did not improve PFS in this biomarker unselected, pretreated cohort. However, some patients had prolonged disease control. TRIAL REGISTRATION NUMBER: NCT03044730.

ABSTRACT

INTRODUCTION: The vast majority of patients who undergo a diagnostic evaluation for microscopic hematuria (MH) do not have occult bladder cancer. Identifying patients with MH at high risk of harboring bladder cancer can allow for a risk adjusted approach to diagnostic interventions with the goal of safely reducing unnecessary evaluations. METHODS: Patients with a new diagnosis of microhematuria during an 8.5 year period were retrospectively identified. All patients who had a complete MH evaluation were randomized to a training or a validation cohort. Logistic regression analysis was performed in the training cohort to identify factors related to a bladder cancer diagnosis and to develop our model. Receiver operating curves to identify bladder cancer were constructed for the training and validation cohort and tested for their ability to discriminate true cases. A nomogram to predict a bladder cancer diagnosis was created. RESULTS: In 4,178 patients split into training and validation cohorts, those diagnosed with bladder cancer were shown to be older, have a greater degree of MH (more RBC/hpf), and were former or current smokers. A nomogram created using this model was able to predict risk of a bladder cancer diagnosis with good discrimination (areas under the curve 0.79, 95% CI 0.75-0.83). A cutoff of 0.01 probability demonstrated a sensitivity of 99.1% and a negative predictive value of 99.7%. CONCLUSION: A nomogram can accurately predict the risk of bladder cancer diagnosed during the evaluation of MH and can potentially be used avoid a significant number of work ups in those at the lowest risk.

ABSTRACT

Introduction: While the incidence of skin cancers continues to rise, there remains a disproportionate lack of introductory training on skin cancer screening and identification of modifiable behaviors in medical curricula. Trainees and students have cited low confidence in their ability to counsel patients and lack of instruction as barriers. Methods: To address this need, we created a 1-hour didactic lecture based on a cognitive teaching framework for third-year medical students during their core primary care clerkship. The session highlighted visual identification of different skin cancers, factors increasing individual risk, and photoprotective behaviors. Session content was based on American Academy of Dermatology recommendations for skin cancer prevention. An assessment of knowledge, behaviors, and attitudes given before, immediately following, and at 6 months after the session was used to determine efficacy. Results: One hundred eight students before and immediately after the session demonstrated significantly improved knowledge (mean correct: 71% presession vs. 99% postintervention, p < .0001). Based on 39 participants completing 6-month follow-up, knowledge remained improved (mean answered correctly: 80%, p < .0001). Confidence in patient counseling on preventive behaviors, risk assessment, and reported likelihood of counseling significantly increased across the three time points (p < .0001 for all attitude questions). Specific topics included appropriate referral to a dermatologist, sunscreen application, and dangers of indoor tanning bed usage. Discussion: Our session on skin cancer screening and prevention demonstrated improvements in medical student knowledge, confidence, and patient counseling likelihood. This introductory curriculum could be adapted for multiple core clerkships or specialties.

ABSTRACT

This trial tested a multicomponent intervention to increase colorectal cancer (CRC) screening among underserved patients. Participants were randomized to: (1) physician + patient intervention, (2) physician-only intervention, or (3) usual care (UC). Study outcomes included patient knowledge, physician recommendation of CRC screening, and screening completion via colonoscopy or stool tests. Among 538 participants, those exposed to the physician + patient intervention had significantly increased knowledge over patients in physician-only (p=.0008) or UC arms (p=.0003). However, there were no statistically significant differences in completion of CRC screening, with 10%, 20%, and 16% of UC, physician-only, and physician + patient participants screened, respectively. In UC, all completed screenings were colonoscopy, whereas in the physician-only and physician + patient arms, 39% and 46% of completed tests were via stool test, respectively. The multicomponent intervention did not increase overall CRC screening, yet results underscore the need to provide patients options for completing CRC screening.

ABSTRACT

Vitiligo is impacted by environmental triggers. We studied the contribution of the microbiome in FH mice, in which depigmentation is mediated by tyrosinase-reactive T cells. The mice received oral antibiotics and were monitored for depigmentation. The microbiome was studied in fecal and skin samples using 16S rRNA analysis. The resulting T-cell distributions were evaluated. In untreated mice, pigment loss did not expand to the pelage, whereas mice in the ampicillin group were approximately 1/3 depigmented at 30 weeks. In contrast to models of autoimmunity that are less dependent on IFN-γ, ampicillin but not neomycin treatment correlated with accelerated disease and reduced bacteria in the fecal pellets. Modified cytokine patterns in the tissue and serum suggest a response that transcends the gut. Ampicillin-induced depigmentation was accompanied by gut but not skin dysbiosis, and reduced T cell numbers in both sites. Neomycin induced a redistribution of gut T cells and an accumulation of skin regulatory T cells. This treatment spurred a Bacteroides-dominated population of fecal bacteria. Reduced diversity is prominent particularly after ampicillin treatment, when the gut is dominated by Pseudomonas species. In line with current concepts relating the microbiome and the immune system, we predict that dietary measures might promote skin health and delay vitiligo onset.
