Addressing the Transition to Adult Health Care for Adolescents and Young Adults with Pancreatic Disorders

INTRODUCTION

 The transition from pediatric to adult health care is a vulnerable time period for adolescents and young adults (AYA). Guidance on how to effectively implement transition support for AYA with recurrent acute pancreatitis (RAP) and chronic pancreatitis (CP) is lacking.

METHODS

 To address this gap, we formed a consortium of pancreatic centers that would work in coordination to test interventions to improve the transition for AYA with RAP and CP. We then performed a baseline assessment of consortium resources and patient transition readiness and developed an educational toolkit for AYA with RAP and CP.  Results: Our consortium consists of three National Pancreatic Centers of Excellence, each with a multidisciplinary team to work with AYA with RAP and CP. While our patients ages 18 to 23 were generally seen at the pediatric centers, the baseline assessment of transition readiness suggests that our patients may have higher transition readiness scores than other populations. The educational toolkit contains both pancreas-specific and general guidance to support AYA with RAP and CP during their transition, including guidance on nutrition, pain management, and finding an adult gastroenterologist.  Conclusions: We have formed a consortium to test interventions to improve the transition to adult health care for AYA with RAP and CP. We have completed a baseline assessment and developed our first intervention: an educational tool kit. Future work planned includes tests of the tool kit and efforts to improve rates of transfer to an adult provider for YA with RAP and CP.

Primary care use and depression screening among young adults with sickle cell disease during their final year of pediatric hematology care

Depression may contribute to transition risk among young adults with sickle cell disease (SCD). It is unclear if they receive depression screening because primary care providers (PCPs) routinely perform this screening, but PCP use declines with age. This retrospective study of young adults with SCD during their final year of pediatric hematology care identified 51 (91%) had PCPs. Among those with hospital system PCPs, 20% saw their PCP and 50% of those were screened for depression by the PCP. This suggests young adults with SCD may not receive depression screening or see PCPs, leading to potential missed opportunities for intervention.

Body image profiles combining body shame, body appreciation and body mass index differentiate dietary restraint and exercise amount in women

This project aimed to establish whether meaningful body image profiles (BIPs) could be identified across measures of body shame, body appreciation, and body mass index (BMI), and whether these profiles could differentiate key health behaviours. Data came from 1200 adult women who responded to an online body image survey. Latent profile analysis was used to identify BIPs based on relative levels of body shame, body appreciation and BMI. Differences in dietary restraint and weekly exercise amount were investigated according to BIP membership. Latent profile analysis revealed four unique BIPs; 1. Appreciative BIP (AP-BIP); 2. Medium Shame BIP (MS-BIP); 3. High Shame BIP (HS-BIP) and 4. Average BIP (AV-BIP). Dietary restraint and exercise amount differed significantly according to BIP in most comparisons. Women in the High Shame BIP exhibited the highest dietary restraint and lowest exercise. Women in the Appreciative BIP exhibited the lowest dietary restraint and highest exercise. Body shame and body appreciation intersect with BMI to form unique profiles (BIPs) that differentiate dietary restraint and exercise. Using BIPs to tailor interventions designed to promote healthful diet and exercise should be considered in public health initiatives.

Using Fume Hood to Reduce Nurses' Exposure to Particulate Matters Dispersed Into the Air During Pill Crushing

BACKGROUND

Pill crushing is a common practice in patient care settings. Crushing pills can disperse particulate matter (PM) into indoor air. The PM is a widespread air pollutant composed of microscopic particles and droplets of various sizes and may carry active and/or inactive ingredients nurses can inhale. This study aimed to quantify PM sizes and concentration in indoor air when pills are crushed and examine the role of a fume hood in reducing particulate pollution.

METHODS

Two scenarios (with and without a fume hood) representing nurses' pill-crushing behaviors were set up in a positive-pressure cleanroom. Two acetaminophen tablets (325 mg/tablet) were crushed into powder and mixed with unsweetened applesauce. The PM sizes and concentrations were measured before and during crushing.

RESULTS

Different sizes of PM, including inhalable, respirable, and thoracic particles, were emitted during medication crushing. The total count of all particle sizes and mass concentrations of particles were significantly lower during crushing when a fume hood was used (p = .00).

CONCLUSION

Pill crushing increases PM and should be considered a workplace safety health hazard for nurses. Healthcare professionals should work under a fume hood when crushing pills and wear proper protective equipment. The findings of significant particulate pollution related to pill crushing suggest that further research is warranted.

Diagnosis of Pulmonary Embolism in Pregnancy

Pulmonary embolism (PE) is a significant cause of obstetric morbidity and mortality. However, over diagnosis related to excessive use of diagnostic testing is also associated with long term major health issues, including impact on future pregnancies and subsequent health care. Accurate diagnosis of PE depends on knowledge of the prevalence of PE in the pregnant population, the a priori probability of a PE based on specific findings in a given patient and understanding of the accuracy of computed tomographic pulmonary arteriography (CTPA), the dominant diagnostic modality employed for this diagnosis. Venous thromboembolism (VTE) is widely considered to be more common in pregnancy. However, this term includes both deep venous thrombosis (DVT) as well as PE. While the former appears to be more common, published data on the prevalence of PE in pregnancy show little or no increase relative to the general population. Given the published data on the sensitivity and specificity of CTPA, a positive reading is more likely to be a false positive unless the probability of a PE in a given patient is at least 5% (a two-hundred-fold increase from baseline). Doubling the probability to 10% (a four-hundred-fold increase) only improves the positive predictive value to about 67%. Strategies to refine the a priori probability of a PE in a given patient are detailed, including scoring systems and D-dimer measurements. A careful history and physical examination and thoughtful development of a differential diagnosis are key elements of clinical practice and should include both the likelihood of each possible diagnosis and the accuracy of diagnostic modalities. This approach should precede the application of a given algorithm. Such a structured approach can decrease utilization and limit false positive diagnoses without increasing morbidity or mortality.

Why "mealtime chatter matters": A process evaluation of a preventive health brief intervention

How parents communicate about food is important for building children's emotional relationships with food. "Mealtime Chatter Matters" (MCM) is an evidence-informed brief intervention providing behavioral strategies for parents focusing on positive communication at mealtimes. This process study explored parents' experiences of the brief intervention. Nine mothers participated in interviews, followed by a qualitative inductive analysis. Findings revealed the strengths and weaknesses of MCM and critical reflections of participants' experiences that can be used to inform future program strategies. This study has important health marketing implications for developing preventive health resources and indicates that future research on mealtime communication is warranted.

Disordered eating prevention: Co-designing a brief intervention for use in Community Child Health Services

Dietary habits established in childhood, often persist into adulthood highlighting the importance of early intervention. However, limited interventions exist promoting "how" to establish healthful eating behaviors in children. To create impactful interventions, it is important they are based on evidence and co-designed with end-users. Fifteen child health nurses participated in this co-design study, underpinned by the Knowledge to Action Framework. Child health nurses reviewed evidence-based statements and then workshopped practical strategies. Findings from the co-design sessions were used to inform the development of a preventive intervention. The study has important health marketing implications for conducting co-design with child health nurses.

Examining the feasibility of a brief parent intervention designed to promote positive food communication with infants

BACKGROUND

Few prevention interventions exist focusing on supporting parents to use positive food communication at mealtimes, for the prevention of disordered eating. "Mealtime chatter matters (MCM)" is a brief intervention designed for parents of infants. The intervention was designed in collaboration with child health nurses (CHNs) to be embedded into usual care. The overall aim of this study was to test the feasibility of the intervention through examining the acceptability of the MCM content and resources and the potential impact of the intervention on parents.

METHODS

This pilot study utilised a mixed methods approach and took place within a regional child health service in Queensland, Australia (October 2021 to June 2022). Participants were parents of infants attending child health education groups and CHNs. The intervention consisted of a brief education session (including accompanying resources), facilitated by a Paediatric Dietitian. The acceptability of MCM content and resources was assessed by both parents and CHNs via self-reported questionnaires and the potential impact on parents assessed via pre-/post-self-reported questionnaires.

RESULTS

Forty-six parents of infants (aged < 8 months) and six CHNs who hosted the intervention and observed the program's delivery participated in the study. MCM content and resources were highly acceptable to parents and CHNs, as both qualitative and quantitative data concurred. How the program may have potentially impacted parenting practices was unclear from the survey results and further investigation is required to better understand these. Tangible lessons and opportunities to further test this intervention were clear from current results.

CONCLUSION

Overall, MCM was acceptable to both parents and CHNs, with the content and resources both being highly valued. Parents reported the content to be informative and engaging and CHNs were keen to have such an intervention available in the future. However, further modification and testing is required of MCM. This feasibility study is an essential first step in supporting parents and CHNs to access an evidence-based intervention with the aim of preventing disordered eating.

Reducing inappropriate polypharmacy for older patients at specialist outpatient clinics: a systematic review

OBJECTIVE

Polypharmacy is associated with negative clinical consequences. The efficacy of deprescribing interventions within medical specialist outpatient clinics remains unclear. Here, we reviewed the research on the effectiveness of deprescribing interventions implemented within specialist outpatient clinics for patients ≥ 60 years.

METHODS

Systematic searches of key databases were undertaken for studies published between January 1990 and October 2021. The diverse nature of the study designs made it unsuitable for pooling for meta-analysis, thus, a narrative review was conducted and presented in both text and tabular formats. The primary outcome for review was that intervention resulted in a change in medication load (either total number of medications or appropriateness of medication). Secondary outcomes were the maintenance of deprescription and clinical benefits. Methodological quality of the publications was assessed using the revised Cochrane risk-of-bias tools.

RESULTS

Nineteen studies with a total of 10,914 participants were included for review. These included geriatric outpatient clinics, oncology/hematology clinics, hemodialysis clinics, and designated polypharmacy/multimorbidity clinics. Four randomized controlled trials (RCTs) reported statistically significant reductions in medication load with intervention; however, all studies had a high risk of bias. The inclusion of a pharmacist in outpatient clinics aims to increase deprescribing, however, the current evidence is mainly restricted to prospective and pilot studies. The data on secondary outcomes were very limited and highly variable.

CONCLUSIONS

Specialist outpatient clinics may provide valuable settings for implementing deprescribing interventions. The addition of a multidisciplinary team including a pharmacist and the use of validated medication assessment tools appear to be enablers. Further research is warranted.

A134 THE PEDIATRIC ENDOSCOPY POCKET GUIDE – DEVELOPMENT OF A NOVEL “IN-THE-MOMENT” ELECTRONIC RESOURCE FOR PEDIATRIC ENDOSCOPY

Background

Endoscopy is vital to pediatric gastroenterology. Performing endoscopic procedures safely, effectively and with age-specific considerations requires integration of technical and cognitive competencies. There are many guidelines for endoscopic diagnosis, classification, and management of pediatric gastrointestinal conditions. To date, there are few collated resources for pediatric endoscopists.

Subspecialty trainee feedback at McMaster University identified the need for an accessible, consolidated resource to improve knowledge and competence. The literature shows a lack of exposure in subspeciality training to uncommon yet high acuity procedures such as gastrointestinal bleeding. In an apprenticeship-based learning model, this poses a challenge for both trainees and trainers. Evidence suggests use of multimedia tools is more effective for learning procedural skills than text alone, which guided the creation of this resource.

Purpose

To develop an “in-the-moment” electronic resource to supplement training of pediatric endoscopic procedures.

Method

A subspeciality trainee and two pediatric gastroenterologists with expertise in medical education and program development identified existing knowledge gaps. An electronic pocket guide with links to relevant guidelines and instructional resources was developed. The guide underwent six rounds of revision to ensure it contained relevant and updated guidelines. A copyright and e-learning expert reviewed the content to certify it complied with copyright laws and McMaster University’s accessibility guidelines. The guide will be uploaded to Pressbooks © which allows for export to multiple formats for distribution.

Result(s)

Based on knowledge gaps identified by local experts, the following six domains were incorporated into the pocket guide:

1. Logistics: safety procedures, colonoscopy preparation regimens, equipment specifications, considerations for urgent endoscopy and reporting guidelines

2. Troubleshooting: patient positioning, loop recognition/management strategies

3. Special tests: method of collection, collection media and lab protocols

4. Scoring systems: validated scoring tools for eosinophilic esophagitis, Barrett’s esophagus, esophageal varices, caustic esophageal injury, bleeding ulcers, and inflammatory bowel disease

5. Endoscopic emergencies: guidelines for esophageal burns, foreign body ingestions and upper gastrointestinal bleeds

6. Endoscopic tools: instructions for tools used in the categories of hemostasis, polypectomy, foreign body removal, esophageal varices, and strictures

Conclusion(s)

This novel teaching tool provides an electronic guide that can be used at all levels of pediatric gastroenterology training to gain familiarity and/or rapidly access resources for complex or infrequently encountered endoscopy techniques. Future studies will aim to evaluate the pocket guide from two aspects – ease of use/accessibility and whether implementation of this guide leads to increased competence with various endoscopic tools and techniques.

Zooming in: The relationship between appearance concerns and perceived performance whilst videoconferencing among Australian adults

Videoconferencing for work/study purposes has increased rapidly due to the COVID-19 global pandemic. Given this practice often involves viewing one's own video image, higher appearance concerns whilst videoconferencing may be linked to poorer performance whereby individuals may not feel they are able to engage or have control during a work/study meeting. The present study cross-sectionally examined whether both facial appearance concerns and fear of negative evaluation during videoconferencing for work/study purposes were directly and indirectly related to performance control and engagement, through self-focused attention and appearance distraction. Adult participants (N = 534, M_age = 26.32, SD = 11.08; 78% female) completed an online survey during the COVID-19 pandemic in Australia. Path analysis revealed direct and indirect effects, suggesting that heightened appearance self-consciousness was associated with greater self- and appearance-focused attention. In turn, this was related to impaired performance during videoconferencing. Multigroup analyses demonstrated that the magnitude of the proposed correlational effects were comparable across men and women. Given the ongoing reliance on videoconferencing, these findings have important theoretical and practical implications.

Management of Pulmonary Arterial Hypertension in Pregnancy: Experience from a Nationally Accredited Center

(1) Background: In pulmonary arterial hypertension (PAH), pregnancy is regarded a contraindication due to high maternal and fetal morbidity and mortality. We report our experience in the management of pregnancies in PAH. (2) Methods: retrospective observational study in a nationally accredited pulmonary hypertension (PH) center from 2013 to 2021. (3) Results: seven pregnancies in six women with PAH, ranging from low to high risk and 21 to 37 years old. Half had known pre-existing PAH before pregnancy. One had a multifetal gestation, and one was pregnant twice under our care. PH medical therapy and serial clinical assessment throughout pregnancy were implemented with focused attention on optimizing right heart function. Delivery was planned by a multidisciplinary team involving PH cardiology, maternal fetal medicine, and obstetric anesthesiology. Patients delivered between 31 and 40 weeks of gestation; five of the seven were via cesarean section. All received regional anesthesia and were monitored in the PH intermediate step-down unit after delivery until discharge. In all cases, delivery was without complications with excellent outcomes for the mother and child. (4) Conclusions: Multidisciplinary and tailored management of PAH in pregnancy, emphasizing optimized right heart function prior to delivery, can result in excellent clinical outcomes in a referral PH center.

Parental Food Communication and Child Eating Behaviours: A Systematic Literature Review

AIM

To review current evidence for parental food communication practices and their association with child eating behaviours.

METHODS

The PRISMA framework guided the reporting of the review; registered with Prospero in July 2020 (blinded for peer review). Eligible studies were critically appraised using the Joanna Briggs Institute tools. Only quantitative studies that included a parental measure of food communication and a child measure of eating behaviour were included.

RESULTS

From 11063 articles 23 were eligible for synthesis. The vast majority (82%) of studies used observational cross-sectional designs. Three involved observing parent-child dyads, with the remainder using questionnaires. Two quasi-experimental designs tested interventions and two randomised control trial were reported. The majority of measures assessing parental food communication were subscales of larger questionnaires. The Caregiver's Feeding Style Questionnaire (CFSQ) was the most direct and relevant measure of parental food communication. Findings of reviewed studies highlighted that "how" parents communicate about food appears to impact child eating behaviours. Using child-centred communication provided promising outcomes for positive child eating behaviours, while parental "diet" communication was found to be associated with poorer dietary outcomes in children.

CONCLUSIONS

Food communication research is in its infancy. However, evidence for the importance of parents' child-focused food communication is emerging, providing a focus for future research and interventions. SO WHAT?: Given the gaps in our understanding about prevention of disordered eating, there is a significant opportunity to explore what food communication strategies may assist parents to communicate about food in a positive way.

Building the Generalist Physician to Support Adolescence and Emerging Adulthood: A Narrative Review

Undergraduate medical education serves as a foundation for the medical student to develop the skills of a generalist physician. Given the "blurring" of the demarcations between childhood and adulthood and the increased scope of pediatric practice, an extra layer has been added to medical education which seeks to address care across the lifespan. While approaches have been developed to teach this layer, clerkship reform has not focused on advancing the clinical science of adolescence. Furthermore, as we look towards the vanguard of entrustable professional activities (EPA), specific attention to transition care for the adolescent has seen minimal attention. Drawing on prior examples of curriculum integration between specialties as well as solutions to complex care management from clinical reasoning, we suggest that attention to the development of the generalist physician requires attention to the combined medicine-pediatrics specialty.

Clinical decision support system RHINA in the diagnosis and treatment of acute or chronic rhinosinusitis

Background

Rhinosinusitis is an inflammation of the sinonasal cavity which affects roughly one in seven people per year. Acute rhinosinusitis (ARS) is mostly, apart from allergic etiology, caused by a viral infection and, in some cases (30–50%), by a bacterial superinfection. Antibiotics, indicated only in rare cases according to EPOS guidelines, are nevertheless prescribed in more than 80% of ARS cases, which increases the resistant bacterial strains in the population.

Methods

We have designed a clinical decision support system (CDSS), RHINA, based on a web application created in HTML 5, using JavaScript, jQuery, CCS3 and PHP scripting language. The presented CDSS RHINA helps general physicians to decide whether or not to prescribe antibiotics in patients with rhinosinusitis.

Results

In a retrospective study of a total of 1465 patients with rhinosinusitis, the CDSS RHINA presented a 90.2% consistency with the diagnosis and treatment made by the ENT specialist.

Conclusion

Patients assessed with the assistance of our CDSS RHINA would decrease the over-prescription of antibiotics, which in turn would help to reduce the bacterial resistance to the most commonly prescribed antibiotics.

The Body Confident Mums challenge: a feasibility trial and qualitative evaluation of a body acceptance program delivered to mothers using Facebook

Background

Motherhood is a time of intense physical, psychological, and identity transformation, and body dissatisfaction may emerge through the process of pregnancy, birth, and adaptation to parenting. We present a feasibility trial of the Body Confident Mums Challenge, a program developed by adapting existing, effective interventions that focus on self-compassion and appreciation of body functionality to be specific to mothers.

Methods

The program was delivered using the social learning function in a closed Facebook group. Qualitative evaluation of evidence of change was conducted by gathering individual written reflections posted during the challenge (n = 120). Feasibility and acceptability was determined using a feedback survey (n = 22).

Results

Participant’s reflective posts indicated that they were embracing self-compassion, and de-prioritising body image concerns during the challenge. Feedback indicated that the program was mostly feasible and acceptable for mothers, with recommendations from some participants relating to slowing the pace of content delivery and reducing the time commitment of the Challenge.

Conclusions

The social media environment may therefore be a useful setting in which to implement brief intervention programs to improve body image and wellbeing.

A qualitative study of fourteen African countries' nursing workforce and labour market

AIM

The aim of this study was to describe factors affecting nursing education and labour markets in countries in East, Central, and Southern Africa, and critical areas for investment.

BACKGROUND

An understanding about the relationship between the supply of nurses (determined by types of educational programmes, and the quantity and quality of nurse graduates), and workforce demand is critical to health policy development.

METHODS

Six focus groups and 14 key informant interviews with nursing leaders and experts were conducted. Participants included government chief nursing officers, registrars of regulatory bodies, association leaders and heads of nursing education. The data were transcribed, coded and analysed using inductive techniques.

FINDINGS

Participants discussed challenges and strengths of nursing education, school and regulatory infrastructure, financing mechanisms for the nursing workforce, the state of nursing jobs and scope of nursing practice.

CONCLUSION

Strengthened regulations and leadership are needed to improve investment in nursing, the quality of nursing education, and working conditions and to promote the achievement of better health outcomes.

IMPLICATIONS FOR NURSING POLICY

Clarifying scope of practice for nurses in the health sector and creating competency-based requirements is important. Governments should establish positions that align with updated competencies and provide fair and safe working conditions. The current and ongoing investment case for nursing requires improved data systems and a commitment to use labour market data for decision-making.

Mumbod? A comparison of body image and dietary restraint among women with younger, older, and no children

Pregnancy and the postpartum period are times of significant body, and body image changes for women. Adult women (N = 885) aged 21 to 47 years old completed an online questionnaire. Mothers of young children (0-5 years) had significantly lower levels of body shame, self-objectification, and dietary restraint than women without children, and women with school-aged (6-10 years) children had significantly lower self objectification than women without children, once we controlled for age. BMI predicted body shame more than motherhood status. This research has implications for the development of appropriate body image interventions for adult women.

It Is a Life Journey: A Roadmap of Teens With Chronic Diseases in Transitioning to Independence

INTRODUCTION

Adolescents with chronic diseases have to cope with a number of challenges in their transition to independence and need to learn self-management. The purpose of this study was to understand the life journey of adolescents and their caregivers.

METHOD

Face-to-face interviews were conducted with 13 adolescents with chronic diseases (e.g., type 1 diabetes, cystic fibrosis, attention deficit hyperactivity disorder, epilepsy) and 13 caregivers (N = 26). Verbal methods were complemented with visual materials. Behavioral models and grounded theory principles guided the analysis of the data.

RESULTS

Participants were grouped according to an "archetype" based on the strategy they adopted to manage their chronic diseases. A life journey map was developed having the stages of transition.

DISCUSSION

This study proposed a new perspective to the life journey, transition stages, and personal archetypes from a patient-centered approach. We argued the need of a multidimensional approach and outlined the differences of archetypes and transition stages.

Engagement in Household Chores in Youth With Chronic Conditions: Health care Transition Implications

This study examined associations between chores engagement, self-management, and transition readiness in youth with chronic conditions. Youths with various chronic conditions attending a therapeutic camp, and their parents participated. Responses of 165 campers and their parents were analyzed (mean camper age 12.3 ± 2.6 years, 47.9% males, 79.4% White). The most common diagnoses were diabetes, spina bifida, cerebral palsy, and sickle cell anemia. Youth who completed chores manifested higher overall health care transition readiness (β^ = 5.17, p = .026) and better communication with providers (β^ = 2.98, p = .006) than youth who completed no chores. Higher chores frequency was not more predictive of higher health care transition readiness scores above and beyond the effects of having chores at all. These results suggest that responsible health care behaviors are related to similar actions in other areas of life. Assignment of chores may promote self-management and health care transition readiness in youth with chronic conditions.

Understanding the Needs of Young People Who Engage in Self-Harm: A Qualitative Investigation

Self-harm is common and associated with adverse outcomes. Research about the risk factors for self-harm has informed the field with regard to clinical interventions that should be delivered for young people who engage in self-harm. Missing is an in-depth understanding of what the triggers of an urge to self-harm might be, including in young people being treated with a clinical intervention. Therefore, there is little knowledge about what techniques young people find helpful to deal with urges to self-harm when they occur. This qualitative study engaged seven young people with lived experience of self-harm in semi-structured interviews about the immediate triggers of the urge to self-harm, and helpful strategies to manage this urge. Thematic analysis using a general inductive approach revealed distressing emotions and a sense of isolation as key themes, with other triggers associated with their induction. Highlighted was the wide range of situations and emotions that can be triggering, such that a further key theme was the idiosyncratic nature of the self-help strategies young people found helpful. Interventions that are developed to support young people who self-harm must address this complexity and findings highlight the need for young people to maintain some autonomy and control while being supported to connect with others for support. This research adds to the literature on self-help strategies to support young people in moments when they are experiencing distressing emotions, feel isolated, and have an urge to self-harm providing important insight to the prevention and intervention for self-harm among young people.

Abstract P6-18-06: Ribociclib treatment benefit in patients with advanced breast cancer with ≥1 dose reduction: Data from the MONALEESA-2, -3, and -7 trials

Background: In the MONALEESA (ML) trials, addition of ribociclib (RIB; cyclin-dependent kinase 4/6 inhibitor) to endocrine therapy (ET) prolonged progression-free survival (PFS) in patients (pts) with hormone receptor-positive (HR+), HER2-negative (HER2–) advanced breast cancer (ABC). RIB was generally well tolerated, with adverse events (AEs) managed effectively by dose modifications. Here we present efficacy data for RIB-based regimens of interest for the proposed indication (i.e. with a non-steroidal aromatase inhibitor [NSAI] or fulvestrant [FUL]) from ML-2, -3, and -7 in pts who received no prior ET for ABC and who had ≥1 RIB dose reduction, to explore the efficacy of RIB in pts who need to dose reduce.

Methods: Pts included in this analysis were: postmenopausal women with HR+, HER2– ABC and no prior ET for ABC who received RIB (600 mg; 3-weeks-on/1-week-off) with letrozole (2.5 mg/day; ML-2 [NCT01958021]), or FUL (500 mg per label; ML-3 [NCT02422615]); and premenopausal women with no prior ET and ≤1 line of chemotherapy for ABC who received RIB with an NSAI (anastrozole: 1 mg/day; letrozole: 2.5 mg/day; ML-7 [NCT02278120]) plus goserelin (3.6 mg every 28 days). Dose reductions for RIB (600 to 400 to 200 mg) were permitted. Primary endpoint was PFS. Secondary endpoints included overall response rate (ORR), clinical benefit rate (CBR), and safety.

Results: In ML-2, -3, and -7, ≥1 RIB dose reduction occurred (n/N) in 169/334 (51%), 92/238 (39%), and 91/246 (37%) pts assigned to RIB, respectively. AEs were the main reason for dose reduction, with all-grade neutropenia the most common AE leading to dose reduction (ML-2 69%, ML-3 80%, ML-7 82%). Median PFS (months) was prolonged with RIB vs placebo in pts without a RIB dose reduction (ML-2: 27.7 vs 16.0; ML-3: not reached [NR] vs 18.3; ML-7: 23.8 vs 13.8); median PFS in pts with ≥1 RIB dose reduction was: ML-2 25.3, ML-3 NR, and ML-7 27.5 months. In pts with measurable disease and without a RIB dose reduction, ORR was 46% (ML-2), 43% (ML-3), and 48% (ML-7); CBR was 70%, 68%, and 79%, respectively. In pts with measurable disease and ≥1 RIB dose reduction, ORR was 62% (ML-2), 57% (ML-3), and 55% (ML-7); CBR was 88%, 85%, and 88%, respectively. The most common Grade 3/4 AEs in the RIB vs placebo groups (≥5% of pts in either ML trial, irrespective of causality or dose reduction) were neutropenia (ML-2: 62% vs 1%; ML-3: 55% vs 0; ML-7: 65% vs 4%), leukopenia (ML-2: 21% vs 1%; ML-3: 12% vs 0; ML-7: 16% vs 1%), hypertension (ML-2: 13% vs 13%; ML-3: 5% vs 5%; ML-7: 2% vs 3%), increased alanine aminotransferase (ML-2: 10% vs 1%; ML-3: 10% vs 0; ML-7: 5% vs 1%), and increased aspartate aminotransferase (ML-2: 6% vs 1%; ML-3: 6% vs 0; ML-7: 4% vs 1%).

Conclusions: Results from the ML-2, -3, and -7 trials suggest that pts who start on 600 mg of RIB and require dose reduction for the management of their AEs, or for other reasons, continue to derive clinical benefit.

Partial maxillectomy for ameloblastoma of the maxilla with infratemporal fossa involvement: A combined endoscopic endonasal and transoral approach

Ameloblastoma represents the most common epithelial odontogenic tumor. Because of the proximity of the maxillary tumors to the orbit and skull base, it should be managed as radically as possible. Maxillectomy, mainly via the transfacial or transoral approach, represents the most common type of surgical procedure. Drawback of these approaches is limited control of the superiomedial extent of the tumour in the paranasal area. We report the use of a combined endoscopic endonasal and transoral approach to manage maxillary plexiform ameloblastoma in a 48-year-old male patient. A combined endoscopic endonasal and transoral approach enabled the radical removal of tumour with a 1.5cm margin of radiographically intact bone with good control from both intrasinusal and intraoral aspects. Adequate visualization of the extent of the lesion (e.g. orbit, infratemporal fossa, anterior cranial base) had been achieved. Non-complicated healing was achieved. This technique of partial maxillectomy led to very good aesthetic and functional results. No recurrence had been noted during review appointments. The combination of endoscopic endonasal and transoral approach for a partial maxillectomy allows sufficient reduction of the defect, thus eliminating the necessity for reconstruction and reducing the morbidity associated with it.

P544The importance of contractile reserve when assessing asymptomatic patients with aortic stenosis

Asymptomatic patients may exhibit symptoms during objective exercise testing, but whether symptoms are due to the obstructively of the valve (typified by the mean gradient) or underlying ventricular function remains unknown. While the mean gradient is an easy parameter to measure no consensus about the measurement of contractile reserve exists. Longitudinal abnormalities may occur in the presence of a normal ejection fraction and the augmentation of these parameters is poorly described. To obtain an objective regarding patients exercise ability is best determined using cardiopulmonary exercise testing. We therefore examined echocardiographic predictors of exercise ability during cardiopulmonary exercise testing.24 asymptomatic patients with moderate to severe or severe aortic stenosis and preserved ejection fraction underwent stress echocardiography with simultaneous cardiopulmonary exercise testing. The primary assessment of exercise ability was the VO2peak and OUES. Echocardiography was measured at rest and during maximal exercise (defined as RER > 1)OUES and VO2peak showed a poor relationship with conventional parameters of severity including peak and mean gradients, AVA and dimensionless index, resting systolic function (by EF and TDI). During exercise systolic augmentation had a good relationship with exercise ability but the exercise mean gradient and exercise LVEF did not.Longitudinal systolic function and particularly systolic augmentation is the strongest predictor of exercise ability when compared to conventional measures of severity.VO2peakOUESS' exerciseRho=0.69 (p=0.001)R= 0.71 (p=0.001)S' restRho=0.52 (p=0.01)R= 0.44 (p=ns)Rest AV max VRho= 0.09 (p=ns)R= -0.08 (p=ns)Rest AV mean PGRho= 0.34 (p=ns)R=-0.10 (p=ns)Exercise AV max VRho=0.43 (p=0.05)R=0.23 (p=ns)Exercise AVmean PGRho= 0.51 (p=0.001)R=0.26 (p=ns)Rest AVARho=0.40 (p=ns)Rho=0.46 (p=0.04)Dimensionless indexRho=0.15 (p=ns)R=0.13 (p=ns)LVEF restRho=-0.18 (p=ns)R=-0.32 (p=ns)LVEF exerciseRho=0.18 (p=ns)R=0.17 (p=ns)S' - systolic velocity; V - velocity; AV - aortic valve; AVA- aortic valve area; LVEF - left ventricular ejection fraction.

A Parental Report of Youth Transition Readiness: The Parent STARx Questionnaire (STARx-P) and Re-evaluation of the STARx Child Report

PURPOSE

The STARx Questionnaire is a self-report measure of health care transition (HCT) readiness in youth with chronic diseases. We aimed to improve reliability and generalizability of the STARx and report initial reliability data on the STARx-P Questionnaire, a self-report measure of parent perspective on their child's HCT readiness.

METHODS

Participants were recruited in several clinics from a large academic hospital in the southeastern USA and via the therapeutic summer camp for children with chronic disease. Children with chronic conditions responded to the 18-question STARx Questionnaire and their parents responded to the parent version, the STARx-P Questionnaire.

RESULTS

IRB-approved consents were obtained from 341 parents (89.4% mothers) and 455 children (Mean age 12.28±2.53; 36.9% Males; 68.6% Caucasian; 22.6% African-American). The most common diagnoses were kidney disease, inflammatory bowel disease, diabetes, cerebral palsy, sickle cell, and cystic fibrosis. Principal component analysis of the STARx-P Questionnaire identified three major subscales in both the child and parent-report: Disease Knowledge, Self-management and Provider Communication. Internal reliability was moderate to good (α=0.545-0.759).

CONCLUSIONS

The STARx-P Questionnaire and STARx Version 4 Questionnaire have demonstrated initial reliability in this multi-institution study. It is the first HCT readiness questionnaire that includes a parent-proxy report which is needed in studies of non-verbal and/or developmentally delayed children. Parent-report can also give unique insights not obtained from self-reports.

TAK-228 (formerly MLN0128), an investigational dual TORC1/2 inhibitor plus paclitaxel, with/without trastuzumab, in patients with advanced solid malignancies

PURPOSE

This phase I trial evaluated the safety, pharmacokinetic profile, and antitumor activity of investigational oral TORC1/2 inhibitor TAK-228 plus paclitaxel, with/without trastuzumab, in patients with advanced solid malignancies.

METHODS

Sixty-seven patients received TAK-228 6-40 mg via three dosing schedules; once daily for 3 days (QDx3d QW) or 5 days per week (QDx5d QW), and once weekly (QW) plus paclitaxel 80 mg/m² (dose-escalation phase, n = 47) and with/without trastuzumab 2 mg/kg (expansion phase, n = 20). Doses were escalated using a modified 3 + 3 design, based upon dose-limiting toxicities in cycle 1.

RESULTS

TAK-228 pharmacokinetics exhibited dose-dependent increase in exposure when dosed with paclitaxel and no apparent differences when administered with or 24 h after paclitaxel. Dose-limiting toxicities were dehydration, diarrhea, stomatitis, fatigue, rash, thrombocytopenia, neutropenia, leukopenia, and nausea. The maximum tolerated dose of TAK-228 was determined as 10-mg QDx3d QW; the expansion phase proceeded with 8-mg QDx3d QW. Overall, the most common grade ≥3 drug-related toxicities were neutropenia (21%), diarrhea (12%), and hyperglycemia (12%). Of 54 response-evaluable patients, eight achieved partial response and six had stable disease lasting ≥6 months.

CONCLUSION

TAK-228 demonstrated a safety profile consistent with other TORC inhibitors and promising preliminary antitumor activity in a range of tumor types; no meaningful difference was noted in the pharmacokinetics of TAK-228 when administered with or 24 h after paclitaxel. These findings support further investigation of TAK-228 in combination with other agents including paclitaxel, with/without trastuzumab, in patients with advanced solid tumors. CLINICALTRIALS.

Abstract P1-14-06: A phase II randomized study with eribulin/cyclophosphamide (ErC) and docetaxel/cyclophosphamide (TC) as neoadjuvant therapy in HER2-negative breast cancer- Final analysis of primary endpoint and correlative analysis results

Background: Eribulin mesylate (Er) is a non-taxane inhibitor of microtubule growth that results in G2-M cell cycle arrest, disruption of normal mitotic spindles and apoptosis. Er demonstrated an overall survival (OS) but not progression free survival (PFS) advantage in anthracycline and taxane refractory breast cancer pts. This OS rather than PFS benefit has been attributed to Er's potential to suppress new metastases through its effects on the epithelial mesenchymal transition (EMT) pathway, even in the absence of an effect on the primary tumor or established metastases. In this study ErC was compared to TC, a standard regimen for (neo) adjuvant treatment. A companion exploratory analysis examined the EMT markers E-cadherin and vimentin, as well as the endothelial marker CD-31 assessing tumor vasculature. Final assessments of the primary endpoint of pathological complete response (pCR) and results of the correlative studies will be presented.

Methods: Women with histologically confirmed invasive HER2-negative (IHC 0-1+ or FISH/SISH negative), cT1-3, cN0-2, M0 (pN3a disease allowed) adenocarcinoma of the breast were eligible. Following a 10 pt lead-in to confirm the safety/feasibility of ErC, pts were randomized 2:1. Arm 1, Er 1.4 mg/m2 IV (Days 1 & 8) and C 600 mg/m2 IV (Day 1); Arm 2, T 75 mg/m2 IV and C 600 mg/m2 IV on Day 1, both regimens administered q 21 days x 6 cycles followed by surgery. Tumor samples were collected at baseline and from residual breast cancer at the time of surgery. Samples were assayed for E-cadherin, vimentin, and CD-31 expression by immunohistochemistry.

Results: Enrollment was completed 4/2014 (76 pts); 10 pts in lead-in phase, 66 pts were randomized (Arm 1, 44; Arm 2, 22). In the randomized population, 77% had invasive ductal adenocarcinoma; median tumor size 3.1 cm (range, 0.4-10cm; 29.5% were T3); axillary nodes clinically positive in 52%. 34% of pts were triple negative (TN). 59 pts (89%) underwent surgery after receiving neoadjuvant chemotherapy (NAC) on study. pCR rates were 9% and 18% on the TC and ErC arms respectively. 4/7 pts with pCR on the ErC arm were TN. tumor samples were analyzed from 69 pts (including lead-in pts) for expression of the EMT biomarkers. Of these, 40 pts had paired pre- and post-treatment samples, and 29 pts had either a pre- or post-treatment sample (including 8 pre-treatment samples from pts who achieved pCR). In pre-treatment tumor specimens (61 samples), E-cadherin levels were modest-high in 80%, vimentin expression was seen in 39%, and CD-31 expression observed in 21% of the samples. Analysis of pre- and post-treatment paired specimens and differential effects according to treatment regimen will be presented.

Conclusion: The observed pCR rate of 18% with ErC in this HER2- pt population was comparable with other NAC regimens. Correlative evaluation of EMT markers and tumor vascular density with response is ongoing and will be presented.

A randomized phase II study of the telomerase inhibitor imetelstat as maintenance therapy for advanced non-small-cell lung cancer

BACKGROUND

Continuation or 'switch' maintenance therapy is commonly used in patients with advancd non-small-cell lung cancer (NSCLC). Here, we evaluated the efficacy of the telomerase inhibitor, imetelstat, as switch maintenance therapy in patients with advanced NSCLC.

PATIENTS AND METHODS

The primary end point of this open-label, randomized phase II study was progression-free survival (PFS). Patients with non-progressive, advanced NSCLC after platinum-based doublet (first-line) chemotherapy (with or without bevacizumab), any histology, with Eastern Cooperative Oncology Group performance status 0-1 were eligible. Randomization was 2 : 1 in favor of imetelstat, administered at 9.4 mg/kg on days 1 and 8 of a 21-day cycle, or observation. Telomere length (TL) biomarker exploratory analysis was carried out in tumor tissue by quantitative PCR (qPCR) and telomerase fluorescence in situ hybridization.

RESULTS

Of 116 patients enrolled, 114 were evaluable. Grade 3/4 neutropenia and thrombocytopenia were more frequent with imetelstat. Median PFS was 2.8 and 2.6 months for imetelstat-treated versus control [hazard ratio (HR) = 0.844; 95% CI 0.54-1.31; P = 0.446]. Median survival time favored imetelstat (14.3 versus 11.5 months), although not significantly (HR = 0.68; 95% CI 0.41-1.12; P = 0.129). Exploratory analysis demonstrated a trend toward longer median PFS (HR = 0.43; 95% CI 0.14-1.3; P = 0.124) and overall survival (OS; HR = 0.41; 95% CI 0.11-1.46; P = 0.155) in imetelstat-treated patients with short TL, but no improvement in median PFS and OS in patients with long TL (HR = 0.86; 95% CI 0.39-1.88; and HR = 0.51; 95% CI 0.2-1.28; P = 0.145).

CONCLUSIONS

Maintenance imetelstat failed to improve PFS in advanced NSCLC patients responding to first-line therapy. There was a trend toward a improvement in median PFS and OS in patients with short TL. Short TL as a predictive biomarker will require further investigation for the clinical development of imetelstat.
