Considering the implementation research-to-practice gap: An experimental evaluation of intervention-general methods for assessing and supporting intervention fidelity through coaching.

Implementation support through coaching-such as with embedded fidelity assessment, performance feedback, modeling, and alliance building-has been empirically supported as a way to increase and sustain interventionists' fidelity levels. However, education research consistently shows that practitioners struggle to monitor and improve interventionists' fidelity using implementation support strategies. One explanation for this type of implementation research-to-practice gap is that evidence-based coaching strategies have significant limitations with respect to their usability, feasibility, and adaptability. This study is the first to experimentally evaluate an evidence-based set of adaptable materials and procedures designed to assess and support the intervention fidelity of school-based interventions. Using a randomized multiple-baseline-across-participants design, we examined the extent to which these materials and procedures would influence intervention adherence and quality of an evidence-based reading intervention. Across all nine interventionist participants, data revealed that the implementation strategies meaningfully improved intervention adherence and quality, and high levels of intervention fidelity maintained 1 month after removing the support procedures. Findings are discussed with respect to how these materials and procedures address a critical need within school-based research and practice as well as how they may help to inform and address the implementation research-to-practice gap in education.

Geographically representative scholarship and internationalization in school and educational psychology: A bibliometric analysis of eight journals from 2002-2016.

Although the discipline of school and educational psychology is arguably international (e.g., relevant research and practice is evident in more than 80 countries), there has been limited research examining the international scholarship published in school and educational psychology journals. Such an assessment is important because it provides one important metric for better understanding the field's level of internationalization. The purpose of this study was to evaluate every article (N = 4456) published from 2002 to 2016 across eight school and educational psychology journals that publish international scholarship. Each article's authorship and participant data were coded and reported in terms of respective country and geographical region. Research questions examined, for example, how the published scholarship aligns with international employment data for school psychologists and whether particular journals published a geographically wider breadth of articles. Overall findings indicated that although the field of school psychology is present in more than 80 countries, the overall scholarship in the reviewed journals predominantly features participants living in, and authors working in, North America or Western Europe. However, one journal (School Psychology International) published relatively more articles with participants from outside of these geographic regions. Also, journals affiliated with a national professional organization largely differed in their percentage of "within-nation" publications (e.g., articles with participants living in the same nation that sponsors the respective journal). Explanations of the data are discussed and several recommendations are made that, if followed, could improve the internationalization and geographical representation of scholarship in school and educational psychology.

Autoimmune Lymphoproliferative Syndrome Masquerading as Posttransplant Lymphoproliferative Disorder.

We present a case of a 2-year-old female presenting with diffuse lymphadenopathy 2 years following orthotopic heart transplant. Initially, she was diagnosed with posttransplant lymphoproliferative disease based on clinical presentation and pathology and she was treated accordingly. Because of persistent lymphadenopathy following the completion of chemotherapy and new onset of autoimmune cytopenias, repeat flow of the lymph node showed an elevated double negative T-cell population prompting evaluation for autoimmune lymphoproliferative syndrome (ALPS). A complete workup was confirmative of a germline Fas mutation consistent with ALPS-FAS. This case emphasizes the importance of considering ALPS-FAS in a patient with lymphadenopathy of unknown cause.

Targeting nano drug delivery to cancer cells using tunable, multi-layer, silver-decorated gold nanorods.

Multifunctional nanoparticles have high potential as targeting delivery vehicles for cancer chemotherapy. In this study, silver-decorated gold nanorods (AuNR\Ag) have been successfully used to deliver specific, targeted chemotherapy against breast cancer (MCF7) and prostate carcinoma (PC3) cell lines. Doxorubicin, a commonly used chemotherapy, and anti-Epithelial cell adhesion molecule (anti-EpCAM) antibodies were covalently bonded to thiolated polyethylene glycol-coated AuNR\Ag, and the resultant system was used to deliver the drugs to cancer cells in vitro. Furthermore, these nanoparticles have a unique spectral signature by surface enhanced Raman spectroscopy (SERS), which enables reliable detection and monitoring of the distribution of these chemotherapy constructs inside cells. The development of interest in a plasmonic nano drugs system with unique spectroscopic signatures could result in a clinical approach to the precise targeting and visualization of cells and solid tumors while delivering molecules for the enhanced treatment of cancerous tumors.

Effects of allergen sensitization on response to therapy in children with eosinophilic esophagitis.

BACKGROUND: In children with eosinophilic esophagitis (EoE) foods are the most common disease triggers, but environmental allergens are also suspected culprits. OBJECTIVE: To determine the effects of environmental allergen sensitization on response to treatment in children with EoE in the southeastern United States. METHODS: Patients 2 to 18 years old who were referred to the Arkansas Children's Hospital Eosinophilic Gastrointestinal Disorders Clinic from January 2012 to January 2016 were enrolled in a prospective, longitudinal cohort study with collection of demographics, clinical symptoms, medical history, allergy sensitization profiles, and response to treatment over time. Comparisons were made between complete responders (peak esophageal eosinophil count <15 per high-power field [HPF]) and nonresponders (>25 eosinophils per HPF) after treatment with diet elimination alone, swallowed corticosteroids alone, or diet elimination and swallowed corticosteroids. Sensitization patterns to environmental allergens found in the southeastern United States were analyzed for the effect on treatment response. RESULTS: A total of 223 individuals were enrolled. Of these, 182 had environmental allergy profiling and at least one endoscopy while receiving proton pump inhibitor (PPI) therapy. Twenty-nine individuals had PPI-responsive EoE and were excluded from further analysis, leaving 123 individuals with non-PPI-responsive EoE who were further analyzed; 72 (58.5%) were complete responders and 33 (26.8%) were nonresponders. Seventeen individuals (13.8%) were partial responders (≥1 but ≤25 eosinophils per HPF) and excluded from further analysis. Nonresponders were more likely to be sensitized to perennial allergens (P = .02). There was no significant difference in response based on seasonal allergen sensitization. Individuals with mold or cockroach sensitization were more likely to fail combination diet and swallowed corticosteroid treatment (P = .02 and P = .002). CONCLUSION: Perennial allergen and mold sensitization may lead to nonresponse to EoE treatment in some patients. Additional studies are needed to further understand the effect of environmental allergens on EoE. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01779154.

Naegleria fowleri: Diagnosis, Pathophysiology of Brain Inflammation, and Antimicrobial Treatments.

Primary amoebic meningoencephalitis (PAM) is a very rare disease with a high mortality rate. PAM is caused by Naegleria fowleri, an amoeba which resides in freshwater lakes and ponds and can survive in inadequately chlorinated pools ( Lopez, C.; Budge, P.; Chen, J., et al. Primary amebic meningoencephalitis: a case report and literature review . Pediatr. Emerg. Care 2012 , 28 , 272 - 276 ). In the past 50 years, there have been over 130 cases of Naegleria induced PAM in the United States with only three known survivors; one survivor was diagnosed and treated at Arkansas Children's Hospital. Successful treatment of PAM started with a rapid diagnosis, extensive antimicrobial therapy including an investigational medication miltefosine, supportive care, an intraventricular shunt, and hypothermia. These treatments address different aspects of the disease process. Increased understanding of the diagnosis and treatment of PAM is important especially for patients who present with meningitis-like findings during the summer months.

Cervical polyps: Is histologic evaluation necessary?

OBJECTIVE: The aim of this study was to examine a series of clinically identified cervical polyps and determine the incidence of significant histologic and concurrent cytologic findings. METHODS: Consecutive cervical polyps from January 2000 through September 2012 were retrieved from the hospital laboratory information system. Histologic evaluation of these polyps was performed, followed by a chart review of clinical findings and correlation with the immediately prior or concurrently collected cervical Papanicolaou (Pap) test results, when available. RESULTS: A total of 369 cervical polyps were identified and reviewed. The patient ages ranged from 18 to 87 years (mean 46.5years). Eight polyps demonstrated squamous dysplasia (6 Cervical Intraepithelial Neoplasia/CIN I, and 2 CIN II/III), while 6 had malignant or atypical/potentially malignant features (2 adenosarcoma, 2 atypical polyps concerning for Mullerian adenosarcoma, 1 endometrioid endometrial adenocarcinoma and 1 adenocarcinoma in-situ). An increased incidence of atypical squamous cells of undetermined significance (ASCUS) and atypical glandular cells not otherwise specified (AGC NOS) Pap diagnoses (12.7% and 6.1%, respectively) was found in women with benign polyps on biopsy. DISCUSSION: We demonstrated a higher rate of clinically significant histologic findings in cervical polyps (14 of 369 cases, 3.7%) compared to previously reported studies. The increase in ASCUS and AGC Pap results was most likely related to reactive and inflammatory changes present in benign polyps. Our results suggest that removal of all cervical polyps with subsequent histologic review is warranted.

Naegleria fowleri That Induces Primary Amoebic Meningoencephalitis: Rapid Diagnosis and Rare Case of Survival in a 12-Year-Old Caucasian Girl.

Primary amoebic meningoencephalitis (PAM) is a rare and almost always fatal disease that is caused by Naegleria fowleri, a freshwater thermophilic amoeba. Our case involves an adolescent female who presented with fever of unknown origin. A lumbar puncture was performed, and the Wright-Giemsa and Gram stained cerebrospinal fluid (CSF) cytospin slides showed numerous organisms. Experienced medical technologists in the microbiology and hematology laboratories identified the organisms as morphologically consistent with Naegleria species. The laboratory made a rapid diagnosis and alerted emergency department care providers within 75 minutes. The patient was treated for PAM with amphotericin, rifampin, azithromycin, fluconazole and aggressive supportive therapy including dexamethasone. The Centers for Disease Control and Prevention (CDC) was contacted, and miltefosine, an investigational medication, was started. Additional treatment included an intraventricular shunt and controlled hypothermia in order to mitigate potential cerebral edema. Our patient is a rare success story, as she was diagnosed swiftly, successfully treated, and survived PAM.

Myeloid sarcoma as the presenting symptom of chronic myelogenous leukemia blast crisis.

Myeloid sarcoma is an extramedullary tumor composed of immature myeloid cells that efface the underlying tissue architecture. It is usually associated with acute myelogenous leukemia, but can be associated with myeloproliferative neoplasms, myelodysplastic disorders, or myeloproliferative/ myelodysplastic syndromes. If it is unrecognized, appropriate chemotherapy may be delayed and survival jeopardized. We present a case of a myeloid sarcoma presenting in an otherwise asymptomatic patient who ultimately was found to have chronic myelogenous leukemia, presenting in blast crisis. We also review the distinct clinical and pathologic features of myeloid sarcoma, as well as treatment of the disease.

Smooth muscle neoplasms of the vulva masquerading as Bartholin gland duct cysts.

Smooth muscle neoplasms of the vulva can be mistaken for Bartholin duct cysts, which can lead to a delay in diagnosis. We present a case of vulvar leiomyoma and a case of leiomyosarcoma that clinically mimicked Bartholin duct cysts. Identification of leiomyosarcomas in this region is particularly important; due to the risk of recurrence, patients may need radiation and/or chemotherapy in addition to adequate surgical treatment and appropriate follow up. Prior series have shown that risk of recurrence is related to inadequate resection and not to the size or grade of tumor. It is critical that pathologists recognize smooth muscle tumors of the vulva and communicate to clinicians the importance of clear margins and wide local excision in cases of malignancy.

The fetal magnetic resonance imaging experience in a large community medical center.

Fetal magnetic resonance imaging (MRI) continues to prove a useful problem solving tool for diagnostic and management decision making issues encountered in the antenatal period. In this paper, we attempt to review basic fetal MRI protocol considerations and demonstrate key imaging findings through multiple modalities, with pathologic correlation in several cases. A study of five fetal MRI cases, from our institution, were selected in order to highlight both the indications for, and benefits obtained from this advanced imaging technique. Fetal MRI proved useful in each case in better defining fetal anomalies, especially where ultrasound (due to drawbacks such as shadowing by pelvic bones) was unable to be completely diagnostic. The more in-depth study made possible by MRI also helped with formulation of disease prognosis and estimation of survival chances of the fetus. Further, MRI as a diagnostic and prognostic tool has become more ubiquitous across the medical community. This imparts tangible benefit to patients, who are now able to find this service within arm's reach. Whereas previously these patients were obligatorily referred up to 90 miles away from our centre for further medical work-up, now a large percentage can obtain their prenatal imaging and perinatal care locally. In addition, medical education benefits as new types of cases, those with pathology of the antenatal period, are retained for work-up and management in these large community settings. Cases from our institution exemplify these types of pathologies, from fetal chest masses to a syndromic presentation of bilateral renal agenesis.
