Building RECOVERY: development of the registry of eating disorders and their co-morbidities OVER time in youth

BackgroundEating disorder (ED) research is limited by the lack of longitudinal cohort studies, particularly those in adolescents, and the lack of inclusion of multiple perspectives and diagnoses. The objective of this study was to describe the development of a longitudinal cohort of adolescents/young adults representing varied ED diagnoses and including perspectives of parents and multi-disciplinary clinicians in addition to those of patients.MethodsPatients of an outpatient ED program who were age 10–27 years, along with their parents and clinicians, were recruited to participate in a longitudinal web-based study. Using univariate, bivariate, and multivariate analyses, we assessed rates of participation among different groups (i.e., parents, patients, different clinical disciplines) as well as factors related to attrition.Results71% of patients, 75% of parents, 56% of adolescent medicine providers, 20% of primary care physicians, 83% of dietitians, and 80% of mental health clinicians invited agreed to participate. At 12 months, 32% of patient participants had not completed their on-line surveys. Attrition rates were higher for parents (55%) and clinicians (45% of nutritionists, 55% of primary care physicians, 51% of Adolescent/Young Adult providers, and 64% of mental health providers) at 12 months.ConclusionsA longitudinal registry of patients with EDs is feasible and efficient when using web-based surveys. However, clinician participation is particularly hard to secure and maintain.

(242) Medicare Beneficiaries with Erectile Dysfunction Who Receive Inflatable Penile Prosthesis: A Real-World, Downstream Revenue Analysis

Abstract Introduction Erectile dysfunction (ED) has a significant negative impact on the quality of life of patients, while also presenting challenges due to the limited access to effective treatment options. Given ED is recognized as a precursor for other chronic health conditions, increasing patient access to ED treatment through men’s health programs may provide economic benefits to a healthcare system through revenue generated from subsequent patient care for other comorbidities. Objective This study quantified the incremental downstream revenue generated from treating men with ED with an inflatable penile prosthesis (IPP) compared to men without ED. Methods This retrospective study used the 100% Medicare Standard Analytical Files to identify men aged 65 years or older with ED who underwent IPP implantation (Current Procedural Terminology 54405) in a hospital outpatient setting between January 1, 2016 and December 31, 2021. To capture 5-year downstream revenue, patients were required to have continuous Medicare Parts A and B enrollment for 12 months pre-index IPP and five years post-index IPP discharge date. Propensity score matching (PSM) was used to match men with ED who received an IPP to men without ED based on demographic and clinical characteristics. Revenue was defined as the sum of the payment for patient services received by hospitals from Medicare, other payor paid amounts, and patient deductibles, copayment, and coinsurance. The total revenue generated was estimated as follows: 1-year pre-IPP, 1-year post-IPP, and 5-year cumulative post-IPP. The 1-year and 5-year downstream revenue was captured post-IPP discharge date and excluded the revenue generated from the index IPP encounter. Revenue was inflated to 2022 US dollars. The mean values and their corresponding standard deviations (SD) were reported. Results Before PSM, the study identified 3,367 men with ED who received IPP and 10,609 men without ED or IPP (mean age: 70; White: 77% vs 79%; Southern region: 53% vs 45%; and Elixhauser comorbidity index score ≥3: 21% vs 20%). Among men undergoing IPP, the average revenue generated was $6,152 (SD: $12,934) at 1-year pre-IPP and $7,898 (SD: $17,794) at 1-year post-IPP. After PSM, the men with ED who received IPP showed a significantly higher 5-year cumulative revenue (n=2,905; mean=$34,571 [SD=$50,234]) compared to the men without ED (n=7,462; mean=$3,189 [SD=$11,527]), respectively. The 5-year cumulative average revenue varied by type of diagnosis: circulatory disease (n=1,597; cost difference=$10,258), urology (n=1,358; cost difference=$2,013), diabetes diagnosis (n=562; cost difference=$2,646), and prostate cancer diagnosis (n=551; cost difference=-$1,043). All statistical analysis results post-PSM are significant at p-value less than 0.05. Conclusions Men with ED who received IPP generated substantially higher revenue for the healthcare system over a 5-year period, nearly ten times as much, compared to men without ED, excluding the initial cost of the IPP procedure. These findings emphasize the financial implications of implementing an advanced ED program aimed at improving access to necessary care for these patients. Healthcare facilities can leverage these insights to effectively allocate resources to deliver critical healthcare to men with ED.

Capacity, Communication, and Coordination Are Key to Successful Implementation of Policy, Systems, and Environmental Strategies at SNAP-Ed Partner Sites in One Southeastern US State: A Qualitative Approach

BackgroundThe United States Department of Agriculture expanded the Supplemental Nutrition Assistance Program (SNAP)-Ed program to all 50 states in 2004. In 2010, the Healthy, Hunger-Free Kids Act required that agencies implementing SNAP-Ed support policy, systems, and environmental (PSE) strategies, in addition to providing direct education (DE). Research has evaluated the impact of PSEs on health, but few studies have investigated the process of PSE implementation. ObjectiveThe objective of this study was to identify facilitators and barriers to PSE implementation at SNAP-Ed partner sites from the perspectives of site contacts and SNAP-Ed implementers. DesignThis study employed a qualitative longitudinal design. The PSE planning and implementation process was observed over 1 year at SNAP-Ed partner sites. Semistructured interviews were conducted with site contacts and SNAP-Ed implementers throughout the year. Participants/settingParticipants were SNAP-Ed implementers (n = 8) and site contacts (n = 18) from 18 partner sites where both PSE and direct education were occurring. SNAP-Ed implementers were debriefed once, and site contacts were interviewed three times over the course of the study. This study was conducted in a Southern US state with SNAP-Ed partner sites that intended to implement PSEs. The duration of data collection was October 2017 through September 2018. AnalysisA thematic analysis of barriers and facilitators to PSE implementation across sites was conducted. ResultsThe PSE implementation barriers were lack of site or implementer readiness or capacity; breakdowns in communication; and DE prioritized over PSE. Facilitators were effective communication; site capacity or readiness; and alignment between site and SNAP-Ed goals. ConclusionsCommunication, capacity, and coordination between SNAP-Ed and partner sites were key components over the timeline of PSE planning and potential implementation.

Teacher talk in an early educator blog: building culture circles for exploring ethics

ABSTRACT This paper examines teacher discourse and the building of culture circles in an asynchronous collaborative blog that combined two different classes in an Early Childhood MS Ed program. Social speech is often considered non-rational. Coupling grounded theory to analyze speech patterns with relational ethics, we argue that teachers engaged in relational discourse that was reflective and social simultaneously. The collaborative blog served as a vehicle for the teachers as they engaged in ethical meaning making.

Factors Influencing Students’ Academic Performance: The Case of Pre-Service Teachers at Dambai College of Education in Ghana

Academic success is the assessment of a learner's ability in a variety of academic areas. Classroom performance, graduation rates, and standardised test results are commonly used by teachers and education administrators to assess student accomplishment. This study, on the other hand, was conducted to assess the factors influencing students’ academic performance at a College of Education in Ghana. The research design employed was the quantitative research method, specifically, a cross-sectional descriptive survey research design. It mainly focused on level 200 pre-service teachers pursuing the B. Ed programme and level 300 pre-service teachers offering the Diploma in Basic Education programme as they are the seniors in their individual programmes. A total of 100 pre-service teachers participated in the study with 51 being females and 49 being males. From the results, some of the factors that influence the pre-service teacher’s academic performance were parents, friends, instructors and the use of teaching and learning materials.

Young adults with eating disorders perspectives on educational resources to support the transition into adult medicine: a thematic analysis

BackgroundEating disorders (EDs) commonly develop in adolescence and can be a chronic condition. Once patients reach the age when it is no longer permitted or appropriate for them to be seen in a children’s healthcare setting, they will need to transition into adult-focused care. This transition period can be challenging, with increased risks of negative health outcomes and disruptions in care. Appropriate educational resources could be an effective support for patients during this transition. Our objectives were to engage patients about the value of developing educational supports and determine how these supports should be structured to be most useful to young adults with EDs.MethodsPatients who had transitioned out of a hospital-based ED program between 2017 and 2020 were invited to participate in a semi-structured interview. Data were analyzed using thematic analysis and qualitative description.ResultsSix young adults (5 females and 1 male) with EDs were interviewed. All participants thought it would be helpful to have an educational resource. Three main themes and seven subthemes were identified. Themes identified related to the unique challenges of transition for ED patients given the age of onset and cycle of symptoms; issues in adult care related to comorbidities and new level of autonomy; and the value of educational resources as both a connection tool and a benchmark. Participants also thought it would be useful to include in any educational resource a summary of their previous treatments, information regarding the transition process, a list of main healthcare providers they saw for their ED, a description of the differences and expectations of the adult system, a list of their follow up appointments, and a list of community and emergency mental health resources.ConclusionsParticipants said that educational supports can play a useful role for young adults with EDs during their transition into adult care. They also provided valuable insights into the desired contents of such supports and expanded on the roles that educational resources could serve for ED patients.

2363. Clinician Educators within Infectious Diseases Society of America (IDSA): Who We Are, What We Do, and What We Need to Succeed

Abstract Background To best support, its membership, the IDSA Medical Education Community of Practice (Med Ed CoP) must know the spectrum of educational duties, common challenges, and needs among its clinician educators (CE). Further, benchmark data for medical education is lacking, including average time to perform duties, salary support, and other resources. Therefore, we conducted a survey to help identify opportunities for institutions and IDSA to support Infectious Disease (ID) CE. Methods We conducted an anonymous electronic mixed-methods survey of ID CE faculty in the United States. The survey link was distributed through the IDSA Med Ed CoP and Program Director discussion forums and receptions at IDWeek 2021. Results Approximately 90/552 (16%) participants completed a majority of the survey. Respondents were evenly distributed by gender and geographic region. A majority of respondents were Caucasian, aged 30 – 49 years, and at the Assistant or Associate Professor level (Table 1). Overall breakdown of allocated duties is as follows; median education full-time equivalent (FTE) was 0.25, clinical FTE=0.50, administrative FTE=0.16, and research FTE=0 (Table 1). Faculty most commonly taught medical students (95%), physician residents (92%), and fellows (88%) and held positions within ID fellowship programs (69%) and medical schools (50%, Table 2). CE's common challenges included competing responsibilities (69%), lack of medical education mentorship (51%), and inexperience in medical education publication (67%). In addition, 77% reported burnout in the past year, frequently due to an increased pandemic-related workload. CEs would like to see opportunities for IDSA grants, advocacy for salary support, and increased opportunities to publish within IDSA journals. CEs report finding reward in their educational work related to: teaching the next generation, developing relationships with learners and colleagues, and promoting others’ success. Conclusion In our study, ID CEs identified common challenges including educational work often requiring more time than allocated FTE, lack of mentors, publishing educational activities, recognition of CE work for promotion, and burnout. Additionally, ID CEs identified practical strategies in which their institutions and IDSA can offer support. Disclosures All Authors: No reported disclosures.

Analyzing the VARK Model of Pre - Service Teachers PCK of Learning

The style of learning refers to the way an individual gains and applies creativity to acquire skills or knowledge. Teachers are accountable for delivering high-quality instruction. As a result, teachers must be able to create an engaging learning environment that draws students' attention to the material being taught. This study will explore the advantages of the VARK (Visual, Aural, Reading or Writing, and Kinesthetic) paradigm as a very effective learning approach. The study's purpose was to investigate whether there is a significant correlation between learning preferences of first-year undergraduate pre-service teachers using the VARK model and their age and programme of study. The population of the participants is 219 students in the B. Ed programme in St. Teresa’s College of Education in Ghana. The purposive sampling was used to select participants for the study however, only 176 of them conveniently responded to the questionnaire. Of these 39 were Early Childhood Education (ECE) students, 116 Primary Education (PE) students and 21 Home Economics (HE) students. The VARK Questionnaire (Version 8.01) was adopted and used for data collection. Descriptively, it was noted that 22(12.5%) of the participants prefer Visual learning only, and 37(21.0%), 19(10.8%) prefer Aural, Reading/Writing and Kinesthetic learning only respectively. Meanwhile, some participants indicated that they prefer learning in more than one of the models, thus 30(25.6%) 13(7.4) and 10(5.7) prefer learning in Bimodal, Trimodal Quadrimodal respectively. Principal Component Analysis (PCA) with varimax rotation was conducted to assess the underlying structure for the 16 items of the VARK learning model. Analysis of Variance (ANOVA) of the main effect of age and programme of study on the VARK learning model of the pre – service teachers were assed. It was found that there is statistically significance difference between the mean scores of the pre – service teachers in the age brackets of 18-23 and 24-29 years of the study (F1, 174 =.001, p < .05). There was a statistically significant difference between programmes of study as determined by one-way ANOVA (F (2,173) = 8.457, p = .001). A Tukey post hoc test revealed that using the VARK learning model there was statistically significantly difference between PE (3.09 ± 1.5, p = .001) and ECE pre – service teachers (4.15 ± 1.7, p = .001) but not PE and HE pre – service teachers (3.75 ± 1.05, p = .301) programmes of study. Again, there was no statistically significant difference between the ECE and HE programme of study (p = .646). It is therefore, recommended teachers should vary their lessons to meet the needs and learning styles of all learnings by the VARK instructional tools or resources.

Behavioural and emotional symptoms of adolescents consulting a specialised eating disorders programme

IntroductionEating disorders (EDs) are complex conditions of multifactorial origin. Their main characteristic is excessive concern about body weight and shape, which causes great discomfort and physical problems and leads to a decrease in quality of life and alterations in the patient’s functionality social environment. The objective of this study is to describe the emotional and behavioural symptoms of adolescents who consult a specialised ED programme in the city of Bogota. MethodsObservational, descriptive, cross-sectional study, for which patients between 11 and 19 years old with an ED diagnosis were recruited. ResultsForty patients with an ED diagnosis were included, of which 92% were female. The mean age of the patients was 16.6±1.9 years; 57% of patients live in a two-parent home and 30% in a single-parent home; 72% of the sample had excellent academic performance; 50% were moderately ill; 60% received pharmacological management with SSRIs; 65% of patients met clinical criteria for anxiety disorder, 30% for depressive disorder; 22.5% had aggression problems; 17.5% criminal behaviour; 72.5% of the sample met clinical criteria for internalising symptoms and 42.5% for externalising symptoms, the majority being patients with a diagnosis of bulimia nervosa. ConclusionsPatients with bulimia nervosa obtained higher scores in the different emotional and behavioural symptoms than those with other eating disorders. This condition is associated with greater psychopathology, which must be examined rigorously at the time of clinical care, seeking to reduce the functional impact that these symptoms generate on the individual.

An investigation of the effects of connective tissue massage in women with migraine: A controlled clinical trial

IntroductionTo investigate the effects of connective tissue massage (CTM) on pain characteristics, accompanying symptoms, medication usage, disability, sleep quality, psychological status, and quality of life in women with migraine. MethodThe study was designed as a prospective controlled clinical trial. Women were allocated into the CTM (CTM + education (Ed) program, n = 8) and control groups (only Ed program, n = 8). One session of Ed and 12 sessions of CTM were performed for 4 weeks. They filled out a headache diary, including pain characteristics, accompanying symptoms, and medication usage, for the pre-, during-, and after-treatment periods. Disability, sleep quality, psychological status, quality of life, and disability were evaluated with the Migraine Disability Assessment Scale, the Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale, and the Headache Impact Test-6, respectively. ResultsThe CTM group showed a significant change in pain, accompanying symptoms (except vomiting), medication usage, Headache Impact Test-6, and Disability with Migraine Disability Assessment Scale scores compared to the control group (p < 0.05). Only the CTM group showed a significant change over time in all parameters of the headache diary except vomiting (p < 0.05). Only Headache Impact Test-6 and Migraine Disability Assessment Scale scores improved in the CTM group (p < 0.05). DiscussionsCTM was superior for reducing pain characteristics, accompanying symptoms, medication usage, disability, and improving quality of life. Conclusion: CTM may be considered as a non-pharmacological and complementary therapy for migraine.

Effectiveness of the SMART Sex Ed program among 13-18 year old English and Spanish speaking adolescent men who have sex with men.

Adolescent men who have sex with men (AMSM) have a high HIV incidence and low utilization of testing and prevention services. However, very few HIV prevention programs exist that focus on the unique sexual health needs of AMSM. SMART is a stepped care package of eHealth interventions that comprehensively address the sexual and HIV prevention needs of AMSM. This study examines the impact of the first step of SMART, "SMART Sex Ed," on 13- to 18-year-old AMSM (n = 983) from baseline to three-month follow-up across 18 separate outcomes measuring HIV prevention attitudes, skills, and behaviors. We observed significant change from baseline to three-month post-intervention in nine HIV-related outcomes (e.g., receipt of HIV and STI test, HIV knowledge), as well as largely consistent effects across demographic subgroups (e.g., race, age, rural, low SES). Analyses observed no effects on condom use behaviors. SMART Sex Ed shows promise as an effective sexual health education program for diverse AMSM.

Perception of Teacher Educators towards 2-Year B.Ed. Programme in Odisha

The nation's development is based on its education. The Teacher Educators train the student teachers to ensure quality in school education by raising the learning levels of the students. The 2-Year Bachelor of Education (B. Ed) is essential to fulfill the said purpose. In the present study it has been found that this Programme is providing sufficient time to acquire proper content knowledge for the development of student teachers. It has been reported that the Teacher Educators of Science stream perceived the programme better in comparison to their Arts counterparts. Like this, the Teacher Educators of higher qualification have perceived the programme better in comparison to their counterparts having inferior qualification. In totto, it has been observed in the present study that the teacher educators are in favour of the 2-Year B. Ed Programme

A Cross-Sectional Geographic Information Systems Study of a Pediatric Emergency Department Child Restraint System Distribution Program

IntroductionA pediatric ED program sought to promote injury prevention through distribution of child restraint systems. Program funds are paid for child passenger safety technician certification of all personnel. Pediatric emergency nurses distributed child restraint systems at hospital discharge and dedicated technicians at fitting stations. Researchers described program characteristics, developed a baseline understanding of program outreach using geographic information systems, and evaluated adherence to manufacturer guidelines with a sensitivity analysis. MethodsThis retrospective cross-sectional study used distribution forms linked to hospital records from 2013 to 2016. Testing for differences used nonparametric methods. Median values and interquartile ranges for weight and height of children were compared with manufacturer guidelines. Geographic information systems visualized recipients’ street addresses and motor vehicle crashes on an underlying base map. ResultsThere were 312 child restraint systems distributed: of which 179 (57.4%) at the hospital, 126 (40.4%) at fitting stations, and 7 (2.2%) missing a location. Among those on Medicaid, 64.4% received a child restraint system at the hospital compared with 35.6% at fitting stations (χ2 = 5.40, P < .02). Fitting stations had limited outreach to rural residents. Finally, results from the sensitivity analysis showed that devices were issued according to manufacturer guidelines. DiscussionDespite the workplace pressures of clinical care, pediatric emergency nurses delivered educational information and demonstrated hands-on installation at similar rates to dedicated technicians. Distribution of child restraint systems through the hospital reached a uniquely underserved population. Further research should investigate methods to improve fitting station outreach among Medicaid recipients.

This study was conducted to determine the study habits/attitudes among the University of Cape Coast one-year, 3-semester B.Ed. Programme Cohort 1 students at Koforidua SDA College of Education study centre. A sample of 185 students was selected using the simple random sampling technique. A self-administered close-ended questionnaire was used to gather data from the respondents sampled for the study. Data were analysed with frequencies, percentages, means, standard deviation, etc. Based on the results of the study, it is concluded that it is good habit for students to read materials prior to it being covered in the class. Again, the study concluded that female and male students do not show variance/difference in study habits. It is recommended that when facilitators actively engage students in lesson, it will help improve their learning habits/attitudes. Also, when facilitators pay attention to individual needs of students, it motivates them to improve their study habits/attitudes.

Facilitators, barriers, and perceived changes of a social behaviour change nutrition programme and economic development programme in rural Bangladesh: A qualitative study

AbstractThis qualitative study explored facilitators, barriers and perceived changes related to programme participation and utilisation among 69 parents of young children who attended a Positive Deviance/Hearth (PDH) programme alone or a PDH programme alongside an Economic Development (PDH/ED) programme to improve child nutrition in rural Bangladesh. Family support stimulated participation in the programmes, while a lack of understanding of the programme's objectives could hinder the effective assets utilisation provided by the ED programme to improve child nutrition. Improvement in child nutritional status was frequently observed in both groups. Proactive engagement and elevated self‐esteem were distinctively reported in the PDH/ED group.

Theoretical Method for Controlling the Flow Rate of the Pumped Medium by Positioning Locking Elements of the Pipe Fittings

Any object located in the pipeline, including the flow meter, leads to a drop in pressure in the pipeline and the need to increase the power of the pumps. Therefore, it seems promising to reduce energy consumption for pumping fluid in the pipeline by reducing the number of flow meters installed after shut-off and control valves and to predict the flow rate of the pumped medium by the position of the locking element in the valve. This will also lead to a reduction in the cost of transporting media by reducing the number of metering devices. In order to solve this complex problem in pipeline transport, the article solves a number of regional problems of hydromechanics based on the finite element method. In order to simplify the acquaintance with these solutions, as well as their practical application by engineers, the article proposes «parametric stationary vortex flow models in such types of shut-off and control valves as a ball valve, butterfly valve, wedge gate valve, angle valve. Without prejudice to generality of the technique, water is considered as an example of a pumped medium. The analysis was performed using FLOTRAN CFD software of ANSYS10 ED program». The article describes in detail the capabilities of both the graphical interface and the command line. Creating models is accompanied by full comments on the actions, which allows any user to master these models. All stages of building models are considered in detail: construction of a solid-state model, selection of elements, appointment of properties of the pumped media, appointment of boundary conditions, as well as solving the problem and viewing the results. «It has been established that the flow rate of the medium is affected both by the geometry of the considered types of shut-off and control valves», and the position of the locking element. The technique can be applied to any designs of pipe fittings associated with calculation of movement of a viscous fluid.
