Applying the National Health Educator Competencies Update Project Model to Health Education

A brief overview of the six-year National Health Educator Competencies Update Project (CUP) research is provided as an introduction to a discussion of applications of the resulting CUP Hierarchical Model. Considerations for application of the model to the professional preparation, credentialing and professional development of health educators are explored. In addition, examples of the applicability of the CUP Hierarchical Model to three different work settings are presented at the Entry, Advanced 1, and Advanced 2 levels of professional practice. The benefits of being guided by a validated practice model are discussed with implications for future research endeavors

Comparison of Clinician Suspicion Versus a Clinical Prediction Rule in Identifying Children at Risk for Intra‐abdominal Injuries After Blunt Torso Trauma

ObjectivesEmergency department (ED) identification and radiographic evaluation of children with intra‐abdominal injuries who need acute intervention can be challenging. To date, it is unclear if a clinical prediction rule is superior to unstructured clinician judgment in identifying these children. The objective of this study was to compare the test characteristics of clinician suspicion with a derived clinical prediction rule to identify children at risk of intra‐abdominal injuries undergoing acute intervention following blunt torso trauma.MethodsThis was a planned subanalysis of a prospective, multicenter observational study of children (50% prior to knowledge of abdominal computed tomography (CT) scanning (if performed). Intra‐abdominal injuries undergoing acute intervention were defined by a therapeutic laparotomy, angiographic embolization, blood transfusion for abdominal hemorrhage, or intravenous fluid administration for 2 or more days in those with pancreatic or gastrointestinal injuries. Patients were considered to be positive for clinician suspicion if suspicion was documented as ≥1%. Suspicion ≥ 1% was compared to the presence of any variable in the prediction rule for identifying children with intra‐abdominal injuries undergoing acute intervention.ResultsClinicians recorded their suspicion in 11,919 (99%) of 12,044 patients enrolled in the parent study. Intra‐abdominal injuries undergoing acute intervention were diagnosed in 203 (2%) patients. Abdominal CT scans were obtained in the ED in 2,302 of the 2,667 (86%, 95% confidence interval [CI] = 85% to 88%) enrolled patients with clinician suspicion ≥1% and in 3,016 of the 9,252 (33%, 95% CI = 32% to 34%) patients with clinician suspicion  50% previamente a conocer la tomografía computarizada (TC) abdominal (si fue realizada). La LIA con necesidad de intervención urgente se definió como laparotomía terapéutica, embolización angiográfica, transfusión de sangre por hemorragia intrabdominal o administración de fluidos intravenosos durante 2 o más días en aquéllos con lesiones pancreáticas o gastrointestinales. Los pacientes se consideraron positivos para la sospecha clínica si la sospecha se documentó como ≥1%. La sospecha > 1% se comparó con la presencia de cualquier variable en la regla de predicción para la identificación de niños con LIA con necesidad de una intervención urgente.ResultadosLos clínicos documentaron su sospecha en 11.919 (99%) de los 12.044 pacientes incluidos en el estudio original. La LIA con necesidad de intervención urgente se diagnosticó en 203 (2%) pacientes. Las TC abdominales se obtuvieron en el SU en 2.302 de los 2.667 pacientes (86%, IC95% = 85% a 88%) incluidos con sospecha clínica ≥1%; y en 3.016 de los 9.252 pacientes (33%, IC95% = 32% a 34%) con sospecha clínica < 1%. La sensibilidad de la regla de predicción para LIA con necesidad de intervención aguda fue mayor que la sospecha clínica ≥1% (197 de 203, 97,0%, IC95% = 93,7% a 98,9%, frente a 168 de 203, 82,8%, IC95% = 76,9% a 87,7%, respectivamente; diferencia de 14,2%, IC95% = 8,6% a 20,0%). La especificidad de la regla de predicción, sin embargo, fue menor que la sospecha clínica (4,979 de los 11.716, 42,5%, IC95% = 41,6% a 43,4%, frente a 9,217 de los 11.716, 78,7%, IC95% = 77,9% a 79,4%, respectivamente; diferencia de –36,2%, IC95% = –37,3% a –35,0%). Treinta y cinco de los pacientes con sospecha clínica < 1% (0,4%, IC95% = 0,3% a 0,5%) tuvieron LIA con necesidad de intervención urgente.ConclusionesLa regla de predicción clínica derivada tuvo una sensibilidad mayor de forma significativa, pero menor especificidad que la sospecha clínica para la identificación de niños con necesidad de una intervención urgente. La mayor especificidad de la sospecha clínica, sin embargo, no se tradujo en la práctica clínica, ya que los clínicos obtuvieron más frecuentemente TC abdominales en los pacientes que consideraron de muy bajo riesgo. Si se validase, esta regla de predicción puede ayudar en la toma de decisiones clínicas sobre el uso de TC abdominal en los niños con traumatismo torácico cerrado.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/113736/1/acem12739.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/113736/2/acem12739_am.pd

Topoisomerase II alpha gene copy loss has adverse prognostic significance in ERBB2-amplified breast cancer: a retrospective study of paraffin-embedded tumor specimens and medical charts

<p>Abstract</p> <p>Background</p> <p>Amplification of the <it>ERBB2 </it>(<it>Her-2/neu</it>) oncogene, which occurs in approximately 25% of breast carcinomas, is a known negative prognostic factor. Available data indicate that a variable number of nearby genes on chromosome 17q may be co-amplified or deleted, forming a continuous amplicon of variable size. In approximately 25% of these patients, the amplicon extends to the gene for <it>topoisomerase II alpha </it>(<it>TOP2A</it>), a target for anthracyclines. We sought to understand the significance of these associated genomic changes for breast cancer prognosis and predicting response to therapy.</p> <p>Methods and patients</p> <p>Archival tissue samples from 63 breast cancer patients with <it>ERBB2 </it>amplification, stages 0–IV, were previously analyzed with FISH probes for genes located near <it>ERBB2</it>. In the present study, the clinical outcome data were determined for all patients presenting at stages I–III for whom adequate clinical follow up was available.</p> <p>Results</p> <p>Four amplicon patterns (Classes) were identified. These were significantly associated with the clinical outcome, specifically, recurrence of breast cancer. The Amplicon class IV with deleted <it>TOP2A </it>had 67% (6/9) cases with recurrence, whereas the other three classes combined had only 12% (3/25) cases (p-value = 0.004) at the time of last follow-up. <it>TOP2A </it>deletion was also significantly associated with time to recurrence (p-value = 0.0002). After adjusting for age in Cox regression analysis, the association between <it>TOP2A </it>deletion and time to recurrence remains strongly significant (p-value = 0.002) whereas the association with survival is marginally significant (p-value = 0.06).</p> <p>Conclusion</p> <p><it>TOP2A </it>deletion is associated with poor prognosis in <it>ERBB2</it>-amplified breast carcinomas. Clarification of the mechanism of this association will require additional study.</p

Pediatric DXA: clinical applications

Normal bone mineral accrual requires adequate dietary intake of calcium, vitamin D and other nutrients; hepatic and renal activation of vitamin D; normal hormone levels (thyroid, parathyroid, reproductive and growth hormones); and neuromuscular functioning with sufficient stress upon the skeleton to induce bone deposition. The presence of genetic or acquired diseases and the therapies that are used to treat them can also impact bone health. Since the introduction of clinical DXA in pediatrics in the early 1990s, there has been considerable investigation into the causes of low bone mineral density (BMD) in children. Pediatricians have also become aware of the role adequate bone mass accrual in childhood has in preventing osteoporotic fractures in late adulthood. Additionally, the availability of medications to improve BMD has increased with the development of bisphosphonates. These factors have led to the increased utilization of DXA in pediatrics. This review summarizes much of the previous research regarding BMD in children and is meant to assist radiologists and clinicians with DXA utilization and interpretation

Age at first birth in women is genetically associated with increased risk of schizophrenia

Prof. Paunio on PGC:n jäsenPrevious studies have shown an increased risk for mental health problems in children born to both younger and older parents compared to children of average-aged parents. We previously used a novel design to reveal a latent mechanism of genetic association between schizophrenia and age at first birth in women (AFB). Here, we use independent data from the UK Biobank (N = 38,892) to replicate the finding of an association between predicted genetic risk of schizophrenia and AFB in women, and to estimate the genetic correlation between schizophrenia and AFB in women stratified into younger and older groups. We find evidence for an association between predicted genetic risk of schizophrenia and AFB in women (P-value = 1.12E-05), and we show genetic heterogeneity between younger and older AFB groups (P-value = 3.45E-03). The genetic correlation between schizophrenia and AFB in the younger AFB group is -0.16 (SE = 0.04) while that between schizophrenia and AFB in the older AFB group is 0.14 (SE = 0.08). Our results suggest that early, and perhaps also late, age at first birth in women is associated with increased genetic risk for schizophrenia in the UK Biobank sample. These findings contribute new insights into factors contributing to the complex bio-social risk architecture underpinning the association between parental age and offspring mental health.Peer reviewe

Gene expression imputation across multiple brain regions provides insights into schizophrenia risk

Transcriptomic imputation approaches combine eQTL reference panels with large-scale genotype data in order to test associations between disease and gene expression. These genic associations could elucidate signals in complex genome-wide association study (GWAS) loci and may disentangle the role of different tissues in disease development. We used the largest eQTL reference panel for the dorso-lateral prefrontal cortex (DLPFC) to create a set of gene expression predictors and demonstrate their utility. We applied DLPFC and 12 GTEx-brain predictors to 40,299 schizophrenia cases and 65,264 matched controls for a large transcriptomic imputation study of schizophrenia. We identified 413 genic associations across 13 brain regions. Stepwise conditioning identified 67 non-MHC genes, of which 14 did not fall within previous GWAS loci. We identified 36 significantly enriched pathways, including hexosaminidase-A deficiency, and multiple porphyric disorder pathways. We investigated developmental expression patterns among the 67 non-MHC genes and identified specific groups of pre- and postnatal expression

Contribution of copy number variants to schizophrenia from a genome-wide study of 41,321 subjects

Copy number variants (CNVs) have been strongly implicated in the genetic etiology of schizophrenia (SCZ). However, genome-wide investigation of the contribution of CNV to risk has been hampered by limited sample sizes. We sought to address this obstacle by applying a centralized analysis pipeline to a SCZ cohort of 21,094 cases and 20,227 controls. A global enrichment of CNV burden was observed in cases (OR=1.11, P=5.7×10−15), which persisted after excluding loci implicated in previous studies (OR=1.07, P=1.7 ×10−6). CNV burden was enriched for genes associated with synaptic function (OR = 1.68, P = 2.8 ×10−11) and neurobehavioral phenotypes in mouse (OR = 1.18, P= 7.3 ×10−5). Genome-wide significant evidence was obtained for eight loci, including 1q21.1, 2p16.3 (NRXN1), 3q29, 7q11.2, 15q13.3, distal 16p11.2, proximal 16p11.2 and 22q11.2. Suggestive support was found for eight additional candidate susceptibility and protective loci, which consisted predominantly of CNVs mediated by non-allelic homologous recombination
