Nuclear Beta-Catenin Expression in Endometrioid Intraepithelial Neoplasia (Atypical Hyperplasia) Does Not Predict Carcinoma on Subsequent Hysterectomy.

Beta-catenin (BC) mutations are associated with a high risk of recurrence in otherwise low-grade, early-stage uterine endometrioid adenocarcinomas. Recent literature suggests nuclear BC expression by immunohistochemistry is highly sensitive and specific for BC mutations. The significance of BC expression in endometrioid intraepithelial neoplasia (EIN/atypical hyperplasia) and its relationship to altered differentiation patterns in EIN has yet to be fully explored. Cases meeting current diagnostic criteria for EIN based on H&E examination were obtained from 2 institutions (years 1999-2014). Patterns of altered differentiation (eg, tubal, squamous morular metaplasia, mucinous, secretory) were noted. Representative blocks were stained for BC, and expression patterns recorded. Follow-up and demographic data was obtained from the electronic medical record. Ninety-six cases were included (84 biopsies, 12 hysterectomies). BC nuclear expression was identified in 41 cases (42.7%), with 33 of 41 demonstrating foci of nonmorular BC staining. BC staining in any component of EIN was not significantly associated with the presence of carcinoma on subsequent hysterectomy (P=0.79). When restricting to nonmorular BC, the results were the same (P=0.56). Cases with tubal differentiation were significantly less likely to demonstrate nonmorular BC than cases with no specific pattern of differentiation (P<0.01). EIN frequently demonstrates BC nuclear positivity, especially in cases without tubal differentiation. BC nuclear expression in EIN does not appear to be associated with an increased likelihood of carcinoma on subsequent hysterectomy. Our results do not support routine use of BC immunohistochemistry as a prognostic biomarker in cases of EIN.

The Primary Tube Versus Trabeculectomy Study: Methodology of a Multicenter Randomized Clinical Trial Comparing Tube Shunt Surgery and Trabeculectomy with Mitomycin C.

PURPOSE: To describe the methodology of the Primary Tube Versus Trabeculectomy (PTVT) Study. DESIGN: Multicenter randomized clinical trial. PARTICIPANTS: Patients with medically uncontrolled glaucoma and no prior incisional ocular surgery. METHODS: Patients are being enrolled at 16 clinical centers and randomly assigned to treatment with a tube shunt (350-mm2 Baerveldt glaucoma implant) or trabeculectomy with mitomycin C (0.4 mg/ml for 2 minutes). MAIN OUTCOME MEASURES: The primary outcome measure is the rate of surgical failure, defined as intraocular pressure (IOP) more than 21 mmHg or reduced by less than 20% from baseline, IOP of 5 mmHg or less, reoperation for glaucoma, or loss of light perception vision. Secondary outcome measures include IOP, glaucoma medical therapy, visual acuity, visual fields, and surgical complications. CONCLUSIONS: Practice patterns vary in the surgical management of glaucoma, and opinions differ among surgeons regarding the preferred primary operation for glaucoma. The PTVT Study will provide valuable information comparing the 2 most commonly performed glaucoma surgical procedures.

Participant use and communication of findings from exome sequencing: a mixed-methods study.

PURPOSE: This study investigated how genome sequencing results affect health behaviors, affect, and communication. METHODS: We report on 29 participants who received a sequence result in the ClinSeq study, a cohort of well-educated, postreproductive volunteers. A mixed-methods design was used to explore respondents' use, communication, and perceived utility of results. RESULTS: Most participants (72%) shared their result with at least one health-care provider, and 31% reported subsequent changes in the health care they received. Participants scored high on the Positive Experiences subscale and low on the Distress subscale of a modified version of the Multidimensional Impact of Cancer Risk Assessment. The majority (93%) shared their result with at least one family member. Participants described deriving personal utility from their results. CONCLUSION: This article is the first to describe research participants' reactions to actionable sequencing results. Our findings suggest clinical and personal benefit from receiving sequencing results, both of which may contribute to improved health for the recipients. Given the participants' largely positive or neutral affective responses and disclosure of their results to physicians and relatives, health-care providers should redirect concern from the potential for distress and attend to motivating patients to follow their medical recommendations.Genet Med 18 6, 577-583.

Symptoms of Persistent Behavior Problems in Children With Mild Traumatic Brain Injury.

OBJECTIVE: To investigate the effects of mild traumatic brain injury (mTBI) in children on symptom ratings of behavior problems across the first-year postinjury. SETTING: Emergency departments of 2 regional children's hospitals. PARTICIPANTS: Parents of 176 children with mTBI and 90 children with orthopedic injury aged 8 to 15 years. DESIGN: Group comparisons of postinjury parent and teacher ratings of child behavior problems controlling for background factors. MAIN MEASURES: Child Behavior Checklist and Teacher's Report Form. RESULTS: For younger but not older children in the sample, children with mTBI compared with children with orthopedic injury had higher postinjury ratings on the Child Behavior Checklist Total Behavior Problem scale (t264 = 3.34, P < .001) and higher rates of T-scores of 60 or more on this scale (odds ratio = 3.00; 95% confidence interval, 1.33-6.77; P = .008). For children with mTBI, hospitalization, motor vehicle accidents, loss of consciousness, and magnetic resonance imaging abnormality were associated with higher parent or teacher ratings. CONCLUSIONS: School-aged children with mTBI are at risk for persistent symptoms of behavior problems, especially if mTBI is more severe or occurs at a younger age. The findings justify monitoring of behavior long after injury and further research to identify risk factors for these symptoms and their association with clinical disorders.

Preferences for results delivery from exome sequencing/genome sequencing.

PURPOSE: The aim of this study was to explore the implications of sequencing information and stated preferences for return of results among research participants. METHODS: Six focus groups were held with 39 ClinSeq participants. The groups included participants who had received results, those who had not, those affected with cardiovascular disease, and healthy adults. Audio recordings of the sessions were transcribed and coded and analyzed for themes. RESULTS: All participants expressed interest in receiving results that are medically actionable, nonactionable, carrier, and less so variants that cannot be interpreted. Most participants preferred to receive results in person, although several endorsed use of Internet-based resources that they could return to. Participants identified benefits for health management along with satisfying curiosity, making scientific contributions, and partnering in research. Value was seen in gaining control over health risks. Concerns were distress and/or fear that may result. Some participants were opposed to or ambivalent about learning certain types of results, particularly those having to do with diseases that were incurable or that might have implications for the health of their children. CONCLUSION: There was relative enthusiasm about the value of learning sequencing information, yet it was tempered by concern about negative feeling responses and aversion to learning about incurable conditions.

How do research participants perceive "uncertainty" in genome sequencing?

PURPOSE: The scope of uncertainty in genome sequence information has no rival in health-care delivery. We present data from adults participating in a National Institutes of Health study using this technology, in which perceptions of uncertainty are hypothesized to be key in predicting decisions to learn and act on genome health information. METHODS: We conducted six professionally moderated focus groups with 39 randomly selected ClinSeq participants varying on whether they had coronary heart disease and had received prior sequence results. We elicited perceptions of the uncertainties associated with genome sequencing using written prompts. RESULTS: Participants perceived uncertainty as a quality of genome information. The majority of participants characterized uncertainty of sequencing information as "changing, fluid, developing, or ground breaking." These responses led to anticipation of more optimistic future outcomes. Fewer participants described uncertainty as "questionable, less accurate, limited, or poorly understood." These perceptions seemed to undermine participants' faith in genome information, leading to feelings of disillusionment. CONCLUSION: Our findings suggest that perceptions of uncertainty are related to epistemological beliefs that inform expectations for the information. Interventions that promote realistic expectations of genome sequencing may mitigate negative responses to uncertainty.

A multicenter analysis of the ophthalmic knowledge assessment program and American Board of Ophthalmology written qualifying examination performance.

OBJECTIVE: To compare the performance on the American Board of Ophthalmology Written Qualifying Examination (WQE) with the performance on step 1 of the United States Medical Licensing Examination (USMLE) and the Ophthalmic Knowledge Assessment Program (OKAP) examination for residents in multiple residency programs. DESIGN: Comparative case series. PARTICIPANTS: Fifteen residency programs with 339 total residents participated in this study. The data were extracted from the 5-year American Board of Ophthalmology report to each participating program in 2009 and included residency graduating classes from 2003 through 2007. Residents were included if data were available for the USMLE, OKAP examination in ophthalmology years 1 through 3, and the WQE score. Residents were excluded if one or more of the test scores were not available. METHODS: Two-sample t tests, logistic regression analysis, and receiver operating characteristic (ROC) curves were used to examine the association of the various tests (USMLE, OKAP examination year 1, OKAP examination year 2, OKAP examination year 3, and maximum OKAP examination score) as a predictor for a passing or failing grade on the WQE. MAIN OUTCOME MEASURES: The primary outcome measure of this study was first time pass rate for the WQE. RESULTS: Using ROC analysis, the OKAP examination taken at the third year of ophthalmology residency best predicted performance on the WQE. For the OKAP examination taken during the third year of residency, the probability of passing the WQE was at least 80% for a score of 35 or higher and at least 95% for a score of 72 or higher. CONCLUSIONS: The OKAP examination, especially in the third year of residency, can be useful to residents to predict the likelihood of success on the high-stakes WQE examination.

Quality of life in pediatric mild traumatic brain injury and its relationship to postconcussive symptoms.

OBJECTIVES: Mild traumatic brain injury (TBI) and injury-related outcomes such as postconcussive symptoms (PCS) may influence health-related quality of life (HRQOL) in children. METHODS: We evaluated HRQOL in 186 8- to 15-year-old children with mild TBI and 99 children with orthopedic injuries (OI). Parents rated the frequency and severity of PCS at an initial assessment within 2-weeks postinjury and rated HRQOL at 3- and 12-months postinjury. RESULTS: The mild TBI and OI groups did not differ in psychosocial HRQOL, but the mild TBI group showed lower physical HRQOL at the 12-month follow-up. Somatic PCS were a significant predictor of physical HRQOL over time, and both cognitive and somatic PCS were significant predictors of psychosocial HRQOL over time. Children with higher PCS at the initial assessment had lower HRQOL scores at later time points. CONCLUSIONS: Effective management of PCS may be associated with improvements in HRQOL following pediatric mild TBI.

Creation of the Association of Pediatric Program Directors Faculty Development for Educators "Nuts and Bolts" Teaching Aids.

Faculty development (FD) continues to be a great need and challenge for faculty engaged in graduate medical education (GME) and such educator development should ultimately benefit learners in GME programs. As a Task Force within the Association of Pediatric Program Directors (APPD) FD Learning Community, our Educator subcommittee utilized multiple needs assessments to develop a novel educator development program called the APPD FD for Educators Nuts and Bolts (Nuts & Bolts) consisting of 1 to 2 page FD teaching aids. This paper outlines the development of these teaching aids and can be used as a reference for developing future Nuts & Bolts teaching aids. The development was based on 1) a defining framework (Glassick's criteria), 2) a clear model for evaluation of the program (Logic model), and 3) development of an assessment tool to demonstrate effectiveness of the teaching aids in FD at the local level. These 3 components help establish the scholarly nature of the FD Nuts & Bolts program. Multiple lessons learned from development of this program are presented to inform others engaged in educator program development. Detailed proposals for use of FD Nuts & Bolts for faculty improvement and plans for generating additional teaching aids are presented.

Survival in Patients with Neovascular Glaucoma Following Tube Shunt Implant or Cyclodestructive Procedure.

Purpose: The study purpose was to assess patient survival after tube shunt implant or cyclodestructive procedure for neovascular glaucoma and to determine whether specific preoperative factors are predictive of survival. Materials and methods: A retrospective chart review was performed on patients with neovascular glaucoma who underwent tube shunt implant and/or cyclodestructive procedure between January 2002 and December 2019 at the Minneapolis Veterans Affairs Health Care System. Patient survival was compared to the age and gender-matched Minnesota population. Cox regression analyses were performed to evaluate preoperative parameters and survival. Results: Tube shunt alone was implanted in 30 eyes, cyclodestruction alone was performed in nine eyes, and two eyes underwent both (n = 41 eyes, 39 patients). The postoperative 5-year survival rate was 62% in neovascular glaucoma patients compared to 80% in controls. Survival did not differ significantly based on neovascular glaucoma etiology. Preoperative best-corrected visual acuity of the neovascular glaucoma-affected eye (p = 0.05) and Charlson Comorbidity Index (p = 0.02) were associated with survival, but preoperative maximum intraocular pressure, hemoglobin A1c, and creatinine were not. The mean intraocular pressure at 6 months postprocedure was 14 mm Hg for tube shunt and 27 mm Hg for cyclodestruction (p = 0.03). Conclusion: Neovascular glaucoma patients have reduced survival, but the majority survived at least 5-year postprocedure. Ophthalmologists should consider patient survival and factors predictive of survival when planning procedures for neovascular glaucoma. Clinical significance: Our findings provide an updated perspective on survival in the setting of neovascular glaucoma and can help ophthalmologists provide patient-centered and holistic care.

Coping strategies as a predictor of post-concussive symptoms in children with mild traumatic brain injury versus mild orthopedic injury.

This study examined whether children's coping strategies are related to post-concussive symptoms following mild traumatic brain injury (TBI) versus orthopedic injury (OI). Participants were 8- to 15-year-old children with mild TBI (n = 167) or OI (n = 84). They rated their current preferred coping strategies and post-injury symptoms at 2 weeks (baseline) and 1, 3, and 12 months post-injury. Children's reported use of coping strategies did not vary significantly over time, so their baseline coping ratings were examined as predictors of post-concussive symptoms across time. Self-ratings of symptoms were positively related to emotion-focused strategies and negatively related to problem-focused engagement after both mild TBI and OI. Higher problem-focused disengagement predicted larger group differences in children's ratings of symptoms, suggesting that problem-focused disengagement moderates the effects of mild TBI. Coping strategies collectively accounted for approximately 10-15% of the variance in children's post-concussive symptoms over time. The findings suggest that coping may play an important role in accounting for children's perceptions of post-concussive symptoms after mild TBI.

Do postconcussive symptoms discriminate injury severity in pediatric mild traumatic brain injury?

OBJECTIVES: To assess whether postconcussive symptoms (PCS) can be used to discriminate injury severity among children with mild traumatic brain injury (TBI). PARTICIPANTS: One hundred eighty-six children with mild TBI, divided into high and low injury severity depending on whether the injury was associated with a loss of consciousness (LOC), and a comparison group of 99 children with orthopedic injuries (OI), all aged 8 to 15 years at the time of injury. MAIN MEASURES: Parent-rated frequency and severity of PCS at initial assessment within 2 weeks postinjury and again at 3 and 12 months postinjury. RESULTS: Ratings of PCS obtained at the initial and 3-month assessments differentiated children with mild TBI from OI, although only ratings at the initial assessment discriminated among all 3 groups. Somatic PCS accounted for most of the discriminatory power. CONCLUSIONS: Overall, the accuracy of group classification was relatively modest, with a large proportion of misclassifications of children in the mild-TBI groups. Although children with mild TBI have more PCS than children with OI, PCS do not permit sufficiently accurate discrimination of mild TBI and injury severity to warrant diagnostic decisions at this time.

Enhancing pediatricians' engagement on social media: the role of board style questions.

This article was migrated. The article was marked as recommended. Background: Social Media is used among medical professionals for collaborative education. Little is known about how case discussions prompt engagement. Objective: To determine the association between item characteristics of board exam-style questions to social media engagement. Methods: This was a prospective cohort study through the American Academy of Pediatrics (AAP) PediaLink FaceBook page, conducted in 2018 over 9 months. Items from the 2017 PREP® questions were ranked in difficulty, then rated in relevance to general pediatrics through content-expert consensus. Thirty-six questions were randomly posted on FaceBook and Twitter weekly. Independent variables included item difficulty rank, difficulty level (easy vs hard), relevance to general pediatrics, and word count. Outcome variables included percent correct responses and total comments under the post. Results: More difficult questions were associated with fewer comments (rho=0.63, p<0.001) and lower correct response percentages (rho=0.39, p=0.02). Easy questions garnered more comments than hard questions (median 18 IQR 13-23 vs median 9.5 IQR 5-14, p=0.001). Correct response percentage was lower for hard questions (90% IQR 85-95% vs. 77% IQR 60-94%, p=0.04). Relevance to general pediatrics and word count did not affect engagement (p > 0.1). Conclusion: Easier practice test items attracted more responses from pediatricians on social media, increasing engagement.

Cognitive reserve as a moderator of postconcussive symptoms in children with complicated and uncomplicated mild traumatic brain injury.

The occurrence of postconcussive symptoms (PCS) following mild traumatic brain injury (TBI) in children may depend on cognitive reserve capacity. This prospective, longitudinal study examined whether the relationship between mild TBI and PCS is moderated by cognitive ability, which served as a proxy for cognitive reserve. Participants included 182 children with mild TBI and 99 children with orthopedic injuries (OI), ranging from 8 to 15 years of age when injured. Mild TBI were classified as complicated (n = 32) or uncomplicated (n = 150) depending on whether they were associated with trauma-related intracranial abnormalities on magnetic resonance imaging. PCS were assessed initially within 3 weeks of injury, and again at 1, 3, and 12 months post injury. The initial assessment also included standardized tests of children's cognitive skills and retrospective parent ratings of pre-injury symptoms. Hierarchical linear modeling indicated that ratings of PCS were moderated jointly by cognitive ability and injury severity. Children of lower cognitive ability with a complicated mild TBI were especially prone to cognitive symptoms across time according to parents and to high acute levels of PCS according to children's self-ratings. Cognitive reserve is an important moderator of the outcomes of mild TBI in children and adolescents.

Relationships among post-concussive symptoms and symptoms of PTSD in children following mild traumatic brain injury.

PRIMARY OBJECTIVE: To investigate the occurrence of post-concussive symptoms (PCS) and symptoms of post-traumatic stress disorder (PTSD) in children following mild traumatic brain injuries (TBI). RESEARCH DESIGN: Longitudinal study comparing the outcomes of mild TBI and orthopaedic injuries (OI) in children aged 8-15. METHODS AND PROCEDURES: One hundred and eighty-six children with mild TBI and 99 with OI were recruited prospectively. Parents rated children's PCS and symptoms of PTSD at 2 weeks, 3 months and 12 months post-injury. One hundred and sixty-seven with mild TBI and 84 with OI completed all assessments. MAIN OUTCOMES AND RESULTS: Controlling for symptoms of PTSD, the mild TBI group demonstrated more PCS than the OI group, although the magnitude of group differences diminished with time. Controlling for PCS, the OI group displayed more symptoms of PTSD than the mild TBI group at baseline, but not thereafter. Symptoms of PTSD and PCS were correlated significantly, but more highly in the OI group than the mild TBI group. CONCLUSIONS: Although PCS and symptoms of PTSD are correlated, children with mild TBI are more distinguishable from children with OI based on PCS than on symptoms of PTSD. The latter symptoms, moreover, do not account for increased PCS following mild TBI in children.
