Helping Educational Leaders Mobilize Evidence (HELM): The iterative redesign of the Leadership and Organizational Change for Implementation (LOCI) intervention for use in schools.

Background: Few "intervention agnostic" strategies have been developed that can be applied to the broad array of evidence-based practices (EBPs) in schools. This paper describes two studies that reflect the initial iterative redesign phases of an effective leadership-focused implementation strategy-Leadership and Organizational Change for Implementation (LOCI)-to ensure its acceptability, feasibility, contextual appropriateness, and usability when used in elementary schools. Our redesigned strategy-Helping Educational Leaders Mobilize Evidence (HELM)-is designed to improve principals' use of strategic implementation leadership to support the adoption and high-fidelity delivery of a universal EBP to improve student outcomes. Method: In Study 1, focus groups were conducted (n = 6) with 54 district administrators, principals, and teachers. Stakeholders provided input on the appropriateness of original LOCI components to maximize relevance and utility in schools. Transcripts were coded using conventional content analysis. Key themes referencing low appropriateness were summarized to inform LOCI adaptations. We then held a National Expert Summit (Study 2) with 15 research and practice experts. Participants provided feedback via a nominal group process (NGP; n = 6 groups) and hackathon (n = 4 groups). The research team rated each NGP suggestion for how actionable, impactful/effective, and feasible it was. We also coded hackathon notes for novel ideas or alignment with LOCI components. Results: Study 1 suggestions included modifications to LOCI content and delivery. Study 2's NGP results revealed most recommendations to be actionable, impactful/effective, and feasible. Hackathon results surfaced two novel ideas (distributed leadership teams and leaders' knowledge to support educators EBP use) and several areas of alignment with LOCI components. Conclusion: Use of these iterative methods informed the redesign of LOCI and the development of HELM. Because it was collaboratively constructed, HELM has the potential to be an effective implementation strategy to support the use of universal EBP in schools.

Our research team designed a strategy (HELM) for school principals to improve the support they provide to staff to implement practices proven to work in research for improving student outcomes. We designed HELM by conducting focus groups with school district administrators, principals, and teachers. Participants were asked for their feedback on how to adapt an existing leadership strategy (LOCI) to the school context. After collecting this feedback, we held a meeting with 15 research and practice experts. During this meeting, the group of experts reviewed the focus group feedback and decided how to incorporate it into the design of the HELM strategy. We believe that collecting this feedback and involving research and practice experts in interpreting and integrating participant feedback into the HELM strategy will make HELM a more effective strategy for supporting school principals' in implementing supports in their schools.

The incremental association of implementation leadership and school personnel burnout beyond transformational leadership.

Successful implementation of school-wide interventions (i.e., delivered to all students by a wide array of school personnel) is key to promoting students' academic achievement and psychosocial development. Yet, the implementation of school-wide interventions is complex and can be psychologically taxing for implementing personnel. If evidence-based practice and program (EBP) implementation goes unsupported, implementation challenges might result in chronic stress among school personnel that leads to burnout. While generally effective leadership tends to decrease educator burnout, implementation-specific leadership may also decrease burnout through its strategic supports for EBP implementation. A series of linear regression and path models were used to examine the concurrent association between transformational (e.g., general) and implementation (e.g., strategic) leadership and burnout and its component parts (i.e., emotional exhaustion, depersonalization, personal accomplishment). In a sample of 338 school personnel, we found transformational and implementation leadership were each significantly associated with decreased burnout. However, transformational leadership was not significantly associated with any of the three burnout components, whereas implementation leadership was significantly associated with increased personal accomplishment. These results suggest both general and strategic forms of leadership are key supports for school personnel burnout and as such, leaders may benefit from training to improve each. Additional implications for schools and future directions to understand how best to support school personnel are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Amyloidosis increase is not attenuated by long-term calorie restriction or related to neuron density in the prefrontal cortex of extremely aged rhesus macaques.

As human lifespan increases and the population ages, diseases of aging such as Alzheimer's disease (AD) are a major cause for concern. Although calorie restriction (CR) as an intervention has been shown to increase healthspan in many species, few studies have examined the effects of CR on brain aging in primates. Using postmortem tissue from a cohort of extremely aged rhesus monkeys (22-44 years old, average age 31.8 years) from a longitudinal CR study, we measured immunohistochemically labeled amyloid beta plaques in Brodmann areas 32 and 46 of the prefrontal cortex, areas that play key roles in cognitive processing, are sensitive to aging and, in humans, are also susceptible to AD pathogenesis. We also evaluated these areas for cortical neuron loss, which has not been observed in younger cohorts of aged monkeys. We found a significant increase in plaque density with age, but this was unaffected by diet. Moreover, there was no change in neuron density with age or treatment. These data suggest that even in the oldest-old rhesus macaques, amyloid beta plaques do not lead to overt neuron loss. Hence, the rhesus macaque serves as a pragmatic animal model for normative human aging but is not a complete model of the neurodegeneration of AD. This model of aging may instead prove most useful for determining how even the oldest monkeys are protected from AD, and this information may therefore yield valuable information for clinical AD treatments.

Use of a capillary specimen in the laboratory to verify a point-of-care international normalized ratio: Avoidance of a venipuncture in a pediatric setting.

INTRODUCTION: Point-of-care (POC) international normalized ratio (INR) values above an institutional cutoff are confirmed in the laboratory using a gold standard venous specimen. This can be problematic in a pediatric setting. METHOD: In this study, 449 consecutive POC INR results were compared to an INR performed in the laboratory on a capillary citrate specimen collected from the same finger-stick. The results were statistically analyzed. RESULTS: The mean INR values from the CoaguChek XS and laboratory were 2.85 ± 1.19 and 2.63 ± 1.11, respectively. There was a good correlation between the methods with r = 0.97. Bland-Altman analysis indicated a bias of 0.22 favoring the CoaguChek XS, with 95% limits of agreement -0.29 to 0.72. Passing and Bablok method comparison resulted in a slope of 0.91 (y = 0.91x + 0.02). An INR of ≤0.5 was found between the methods in 89% of cases and 84% agreement was noted (κ = 0.69). CONCLUSION: Comparing the capillary INR laboratory results to studies involving a venous specimen, the capillary specimen performed with equivalence. Thus, a capillary citrate specimen can be collected from the same finger-stick used to perform the POC INR for confirmation in the laboratory. This avoids the trauma of a venous collection in such a situation.

Subtalar Dislocations: Case Series Inclusive of the Rare Anterior Subtalar Dislocation and Review of the Literature / Dislocaciones subtalares: serie de casos con inclusión de la rara dislocación subtalar anterior y revisión de la literatura

ABSTRACT Subtalar dislocations were first described by Judey and Dufaurest in 1811. These dislocations represent only 1-2% of all joint dislocations, making them a rare injury. In this rare injury, there are four variations with differing clinical presentations. The clinical picture may vary from a dramatic deformity (as in medial and lateral dislocations) to a more subtle presentation (as in anterior and posterior dislocations). This case series highlights the variations in clinical presentations and the management difficulties associated with each subtype.

RESUMEN Las dislocaciones subtalares fueron por primera vez descritas por Judey y Dufaurest en 1811. Estas dislocaciones representan solamente el 1-2% de todas las dislocaciones de las articulaciones, por lo que constituye una lesión poco frecuente. Esta rara lesión se caracteriza por cuatro variaciones con presentaciones clínicas que difieren. El cuadro clínico puede variar desde una deformidad dramática (tal cual ocurre en las dislocaciones intermedias y laterales) hasta una presentación más sutil (como en el caso de las dislocaciones anteriores y posteriores). Esta serie de casos destaca las variaciones en las presentaciones clínicas y las dificultades en el tratamiento asociado con cada subtipo.

Maternal vaccination as a Salmonella Typhimurium reduction strategy on pig farms.

AIMS: The control of Salmonella in pig production is necessary for public and animal health, and vaccination was evaluated as a strategy to decrease pig prevalence. METHODS AND RESULTS: The study examined the efficacy of a live Salmonella Typhimurium vaccine, administered to sows on eight commercial farrow-to-finish herds experiencing clinical salmonellosis or Salmonella carriage associated with S. Typhimurium or its monophasic variants. Results of longitudinal Salmonella sampling were compared against eight similarly selected and studied control farms. At the last visit (~14 months after the start of vaccination), when all finishing stock had been born to vaccinated sows, both faecal shedding and environmental prevalence of Salmonella substantially declined on the majority of vaccinated farms in comparison to the controls. A higher proportion of vaccine farms resolved clinical salmonellosis than controls. However, Salmonella counts in positive faeces samples were similar between nonvaccinated and vaccinated herds. CONCLUSIONS: The results suggest that maternal vaccination is a suitable option for a Salmonella Typhimurium reduction strategy in farrow-to-finish pig herds. SIGNIFICANCE AND IMPACT OF THE STUDY: Salmonella vaccines have the potential to reduce the prevalence of Salmonella in pigs and result in a reduction of human cases attributed to pork.

The unusual osteochondroma: A case of snapping scapula syndrome and review of the literature.

Snapping scapula syndrome is a rare condition characterized by crepitus of the scapula on motion of the ipsilateral upper extremity. It may be quite painful and disabling. The majority of cases are due to bursal and muscular disorders. Snapping scapula syndrome secondary to an underlying osteochondroma is an even more infrequent phenomenon. The case presented highlights the unusual post pubertal growth of an osteochondroma of the scapula that progressed to develop a snapping scapular syndrome. Review of the literature revealed less than fifty reported cases of this phenomenon secondary to an underlying osteochondroma.

Connecting the Libraries and Athletics through Instruction and Outreach.

This column describes the approaches taken by librarians and staff at James Madison University (JMU) Libraries & Educational Technologies (LET) to extend library support to university athletics. The model resembles that used for outreach to academic programs and was first adapted to the semi-clinical, nonacademic Strength & Conditioning Department, then to JMU Athletics as a whole. Librarians offered targeted instructional sessions, orientations, and asynchronous learning modules embedded in the learning management system. This new relationship has provided an opportunity for broader collaboration, increasing LET's presence across campus.

Food addiction in children: Associations with obesity, parental food addiction and feeding practices.

Food addiction research in children is limited, and to date addictive-like eating behaviors within families have not been investigated. The aim of this study is to understand factors associated with addictive-like eating in children. The association between food addiction in children with obesity, parental food addiction, and parental feeding practices (i.e., restriction, pressure to eat, monitoring) was investigated. Parents/primary caregivers (aged≥18years) of children aged 5-12years, recruited and completed an online cross-sectional survey including demographics, the Yale Food Addiction Scale (YFAS), and the Child Feeding Questionnaire (CFQ). Parents, reporting on themselves and one of their children, were given a food addiction diagnosis and symptom score according to the YFAS predefined criteria. The total sample consisted of 150 parents/primary caregivers (48% male) and 150 children (51% male). Food addiction was found to be 12.0% in parents and 22.7% in children. In children, food addiction was significantly associated with higher child BMI z-scores. Children with higher food addiction symptoms had parents with higher food addiction scores. Parents of FA children reported significantly higher levels of Restriction and Pressure to eat feeding practices, but not Monitoring. Children with elevated YFAS-C scores may be at greater risk for eating-related issues.

Parents' perception of quality of life in their sons with haemophilia.

AIM: Quality of life (QOL) in haemophilia involves both physical and psychological issues. This study was performed to determine parents' perceptions of the QOL of their sons with haemophilia and compare this to their children's own assessment. METHODS: In this study, we used the Haemo-QoL questionnaire for haemophilia, to compare the responses of 22 parents to the responses of their children within the age groups 4-7, 8-12 and 13-16 and also for the severity groups mild versus moderate-severe. RESULTS: In the 4-7 age group, the children considered their QOL to be less than that estimated by their parents for a number of areas, while in the 8-12 age group the parents considered the QOL for their children to be lower than that estimated by the children themselves. In the 13-16 age group, there was almost universal agreement on QOL between the children and their parents apart from the subscale of school and sport (P = 0.04). Within the severity groupings, there was much more concordance between the parents and children. The only significant difference between parents and children was for physical health in the mild group (P = 0.03). In the moderate-severe groups, no results were significant, however, five of the subscales showed borderline significant (P < 0.1) results. CONCLUSIONS: Parental perceptions of QOL of their sons changes with the age of the child and the severity of the haemophilia. These perceptions need to be taken into account when developing an overall care strategy involving both the child and parent.

An in-vitro investigation into the efficacy of disinfectants used in the duck industry against Salmonella.

In 2010, 81 confirmed cases of Salmonella Typhimurium DT8 were reported across England and Northern Ireland - an increase of 26% from 2009 and 41% since 2008. Five cases were hospitalized and one death reported, with a strong association found between cases and the consumption of duck eggs. Once present on farms, Salmonella may become persistent and can survive for long periods of time in residual organic matter, increasing risk of infection for follow-on flocks if cleaning and disinfection is not carried out effectively. The aim of this study was to investigate the efficacy of a range of disinfectants used by the duck industry against Salmonella using laboratory models. Sixteen products were selected from seven chemical groups and the Minimum Inhibitory Concentration and Minimum Bactericidal Concentrations determined. Each product was also tested at the recommended general orders (GO) concentration using a faecal suspension model to mimic boot dips and a surface contamination model to simulate contaminated building fabric and equipment. In the faecal suspension model, all products were effective at 2 × GO concentration, and activity was more inconsistent at GO concentration. At 0.5 × GO concentration, iodine-based and quaternary-ammonium-compound-based products were significantly less effective than products within other chemical groups (P < 0.001). Glutaraldehyde-based products were significantly more effective than the other products in the surface contamination tests (P < 0.001). Chlorocresol-based products were found to be most effective for use in boot dips and aldehyde-based products for surface disinfection, although there was variability between products within a chemical group.

Point-of-care management of urogenital Chlamydia trachomatis via Gram-stained smear analysis in male high-risk patients. Diagnostic accuracy and cost-effectiveness before and after changing the screening indication at the STI Clinic in Amsterdam.

OBJECTIVES: To measure the effect of changing the point-of-care (POC) testing algorithm of urogenital chlamydia for all male high-risk patients to those with only symptoms with respect to: diagnostic accuracy, loss to follow-up, correctly managed consultations and costs. METHODS: Retrospective comparison of the diagnostic accuracy and cost-effectiveness of Gram-stained urethral smear analysis for the POC management of urogenital Chlamydia trachomatis infections. Between 2008 and 2009 Gram-stained urethral smear analysis was offered to all men irrespective of symptoms; between 2010 and 2011 only to those with symptoms. The Aptima CT assay was the reference diagnostic test. RESULTS: The number of examined Gram-stained smears in the two periods was respectively 7185 (2008-2009 period) and 18,852 (2010-2011 period). The sensitivity of the Gram stain analysis was respectively 83.8% (95% CI 81.2% to 86.1%) and 91.0% (95% CI 89.5% to 92.3%) (p<0.001). The specificity was respectively 74.1% (95% CI 73.0% to 75.2%) and 53.1% (95% CI 51.8% to 54.4%) (p<0.001). The positive predictive value was low in both periods, respectively 31.7% (95% CI 29.8% to 33.6%) and 35.6% (95% CI 34.1% to 37.1%) (p=0.002), whereas the negative predictive value was high, respectively 97.0% (95% CI 96.4% to 97.4%) and 95.4% (95% CI 94.6% to 96.1%) (p=0.002). The loss to follow-up rate between 2008-2009 and 2010-2011 was, respectively, 1.8% (95% CI 1.0% to 2.9%) vs 2.3% (95% CI 1.7% to 3.0%) (p=0.36). There was a small difference in overtreatment, 68.0% (95% CI 66.0% to 69.8%) vs 64.1% (95% CI 62.6% to 65.5%) (p=0.001). The cost per correctly managed consultation was 14.3% lower in the 2010-2011 period (€94.31 vs €80.82). The percentage of delayed treated infections was significantly lower in the 2008-2009 period (10.5%) compared with the 2010-2011 period (22.8%) (p<0.001). CONCLUSIONS: With a high sensitivity in male high-risk patients, the Gram-stained urethral smear is a useful POC test to detect urogenital C. trachomatis. When offered only to men with urogenital symptoms the specificity decreases but the cost per correctly managed consultation is reduced with 14.3% without a significant difference in loss to follow-up but with a significantly higher rate of delayed treatment.

Pediatric thrombotic events: a single-center study.

Recent literature has reported an apparent increase in the incidence of pediatric venous thromboembolism over the last 10 years. In our study, data were collected from all children (ages 0 to 18 y) with a thrombotic event between January 2000 and May 2012, to determine whether an increased incidence of thromboembolism (TE) was evident and to investigate mitigating factors in the development of the TE. A total of 134 patients were entered into the study, 42% under the age of 1 year. There was no conclusive evidence of an increased incidence in our population over the period of the study. Within our population the peripheral venous system was the most common location for TE followed by cerebral vascular accidents. A thrombophilic risk factor was found in 84% of the patients. In our study 4.5% of the children had a second event.

Costs and cost-effectiveness of community health workers: evidence from a literature review

This study sought to synthesize and critically review evidence on costs and cost-effectiveness of community health worker (CHW) programmes in low- and middle-income countries (LMICs) to inform policy dialogue around their role in health systems.

Comparison of two Gram stain point-of-care systems for urogenital gonorrhoea among high-risk patients: diagnostic accuracy and cost-effectiveness before and after changing the screening algorithm at an STI clinic in Amsterdam.

OBJECTIVES: To compare point-of-care (POC) systems in two different periods: (1) before 2010 when all high-risk patients were offered POC management for urogenital gonorrhoea by Gram stain examination; and (2) after 2010 when only those with symptoms were offered Gram stain examination. METHODS: Retrospective comparison of a Gram stain POC system to all high-risk patients (2008-2009) with only those with urogenital symptoms (2010-2011) on diagnostic accuracy, loss to follow-up, presumptively and correctly treated infections and diagnostic costs. Culture was the reference diagnostic method. RESULTS: In men the sensitivity of the Gram stain was 95.9% (95% CI 93.1% to 97.8%) in 2008-2009 and 95.4% (95% CI 93.7% to 96.8%) in 2010-2011, and in women the sensitivity was 32.0% (95% CI 19.5% to 46.7%) and 23.1% (95% CI 16.1% to 31.3%), respectively. In both periods the overall specificity was high (99.9% (95% CI 99.8% to 100%) and 99.8% (95% CI 99.7% to 99.9%), respectively). The positive predictive value (PPV) and negative predictive value (NPV) before and after 2010 were also high: PPV 97.0% (95% CI 94.5% to 98.5%) and 97.7% (95% CI 96.3% to 98.6%), respectively; NPV 99.6% (95% CI 99.4% to 99.7%) and 98.8% (95% CI 98.5% to 99.0%), respectively. There were no differences between the two time periods in loss to follow-up (7.1% vs 7.0%). Offering Gram stains only to symptomatic high-risk patients as opposed to all high-risk patients saved €2.34 per correctly managed consultation (a reduction of 7.7%). CONCLUSIONS: The sensitivity of the Gram stain is high in men but low in women. When offered only to high-risk patients with urogenital symptoms, the cost per correctly managed consultation is reduced by 7.7% without a significant difference in accuracy and loss to follow-up.

The use of a gas chromatograph coupled to a metal oxide sensor for rapid assessment of stool samples from irritable bowel syndrome and inflammatory bowel disease patients.

There is much clinical interest in the development of a low-cost and reliable test for diagnosing inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS), two very distinct diseases that can present with similar symptoms. The assessment of stool samples for the diagnosis of gastro-intestinal diseases is in principle an ideal non-invasive testing method. This paper presents an approach to stool analysis using headspace gas chromatography and a single metal oxide sensor coupled to artificial neural network software. Currently, the system is able to distinguish samples from patients with IBS from patients with IBD with a sensitivity and specificity of 76% and 88% respectively, with an overall mean predictive accuracy of 76%.

An evaluation of pharmacogenomic information provided by five common drug information resources.

INTRODUCTION: This study evaluated whether pharmacogenomic information contained in the Food and Drug Administration (FDA)-approved package inserts of sixty-five drugs was present in five drug information resources. METHODS: The study searched for biomarkers from the FDA package inserts in 5 drug information sources: American Hospital Formulary Service Drug Information (AHFS), Facts & Comparisons 4.0 (Facts), ePocrates Online Free (ePocrates Free), Lexicomp Online (Lexicomp), and Micromedex 2.0. Each resource had the opportunity to present biomarker information for 65 drugs, a total of 325 opportunities. A binary system was used to indicate presence or absence of the biomarker information. A sub-analysis was performed on the 13 most frequently prescribed drugs in the United States. RESULTS: Package insert biomarker information was available, on average, for 81.5% of the 65 FDA-listed drugs in 2011. Percent availability for the individual resources was: Lexicomp, 95.3%; Micromedex 2.0, 92.3%; Facts, 76.9%; AHFS, 75.3%; and ePocrates Free, 67.7%. The sub-analysis of the 13 top drugs showed Lexicomp and Micromedex 2.0 had the most mentions, 92.3%; ePocrates Free had the least, 53.8%. CONCLUSION: The strongest resource for pharmacogenomic information was Lexicomp. The gap between Lexicomp and ePocrates Free is concerning. Clinicians would miss pharmacogenomic information 6.6 times more often in ePocrates Free than in Lexicomp. IMPLICATIONS: Health sciences librarians should be aware of the variation in biomarker availability when recommending drug resources for licensing and use. Librarians can also use this study to encourage publishers to include pharmacogenomics information from the package insert as a minimum standard.
