How well do parents identify their child's baby teeth? Engagement and accuracy of parent-reported information on a tooth checklist survey.

OBJECTIVES: Naturally exfoliated primary teeth are being increasingly collected in child development studies. Most of these odontological collections and tooth biobanks use parent-reported information from questionnaires or tooth checklists to collect data on offspring teeth. To the best of the authors' knowledge, no studies have assessed parental engagement in tooth checklists, nor parental accuracy in identifying their child's baby tooth. This study aimed to evaluate these dimensions by analysing data from the about this tooth checklist returned with donated primary teeth in a natural experimental study called STRONG (the Stories Teeth Record of Newborn Growth). METHODS: Parental self-reported information were analysed on checklists returned with 825 primary teeth belonging to 199 children. The percentage of blank answers was calculated for each question. The accuracy of parents-reported tooth identification was evaluated by comparing parental ratings to researchers' ratings. Reliability of researchers' tooth identification was first evaluated by calculating intra-observer and inter-observer agreements, as well as Cohen's Kappa values. The percentage of accuracy of parents' tooth identification (relative to researcher's) was then calculated, and logistic regressions were used to evaluate if time elapsed between when exfoliation occurred and the checklist was completed associated with parental accuracy in tooth identification. RESULTS: Parents returned 98.4% of the checklists and completed 74.9% to 97.7% of the questions. Excellent reliability was demonstrated for researchers' intra- and inter-rater tooth identification (agreement percentages >90%; Cohen's Kappa values >.83). Moderate accuracy of parents-reported tooth identifications was found, with parents correctly identifying 49.5% of the donated tooth. Better parental accuracies were highlighted for partial identifications (87.1% of correct jaw, 75.6% of correct tooth type, and 65.8% of correct lateralization). Logistic regressions showed the odds of correct parental identifications decreased on average by 1.8% every 30 days of distance between tooth exfoliation and checklist completion. CONCLUSIONS: While parental engagement is high, parents-reported tooth identifications have moderate accuracy, which decreases over time. High accuracy is however found for partial identifications. Parent-reported information on the accompanying questionnaire of naturally exfoliated primary teeth collection or tooth biobanks, even when filled in a long time after exfoliation took place, should be encouraged. However, expert identifications of teeth should remain best practice.

Behavior ratings of executive functions index multiple domains of psychopathology and school functioning in child psychiatric outpatients.

Behavior rating scales of executive functions (EFs) are convenient and associate with academic and other outcomes; however, prior studies indicate limited correlations with psychometric tests of EFs. To better understand their potential for clinical utility, we examined the extent to which parent ratings on the Behavior Rating Inventory of Executive Function (BRIEF) related to psychopathology constructs and psychometric test scores in a sample of N = 692 psychiatric outpatients aged 8-17. Then, in a subsample of the youth (N = 261), we related the BRIEF, psychopathology constructs, and psychometric test scores to teacher ratings of school functioning. BRIEF scales were significantly associated with multiple types of psychopathology including ADHD, autism spectrum, mood, anxiety, conduct, oppositional defiant, and psychotic disorders. While the BRIEF showed limited associations with psychometric EF tests, its Global Executive Composite score explained additional variance in teacher-reported functioning beyond what was predicted by clinical diagnoses (additional explained variance of 9.9% in study skills) and psychometric tests (additional explained variance of 2.1% in learning problems and 4.5% in study skills). The Global Executive Composite was not significantly related to teacher-rated school functioning after psychiatric symptoms were accounted for. These findings support further investigation of the unique contribution of the BRIEF in clinical practice.

Pragmatic fidelity measurement in youth service settings.

Background: Fidelity measurement is critical for developing, evaluating, and implementing evidence-based treatments (EBTs). However, traditional fidelity measurement tools are often not feasible for community-based settings. We developed a short fidelity rating form for the Collaborative Problem Solving (CPS) approach from an existing manualized coding system that requires extensive training. We examined the reliability and accuracy of this short form when completed by trained observers, untrained observers, and self-reporting providers to evaluate multiple options for reducing barriers to fidelity measurement in community-based settings. Methods: Community-based treatment providers submitted recordings of youth service sessions in which they did, or did not, use CPS. For 60 recordings, we compared short-form fidelity ratings assigned by trained observers and untrained observers to those provided by trained observers on the manualized coding system. For 141 recordings, we compared providers' self-reported fidelity on the short form to ratings provided by trained observers on the manualized coding system and examined providers' accuracy as a function of their global fidelity. Results & Conclusions: The short form was reliable and accurate for trained observers. An assigned global integrity score and a calculated average of component scores on the short form, but not component scores themselves, were reliable and accurate for observers who had CPS expertise but no specific training on rating CPS fidelity. When providers self-reported fidelity on the short form, their global integrity score was a reliable estimate of their CPS integrity; however, providers with better CPS fidelity were most accurate in their self-reports. We discuss the costs and benefits of these more pragmatic fidelity measurement options in community-based settings.

Developing brief, easy-to-use, and reliable tools to measure how well providers deliver evidence-based treatments (EBTs) in community clinical settings is critical to ensure the benefits of EBTs. However, reliable tools are often too time-consuming and not feasible to use in community settings because they require independent observers to receive intensive training on a coding system and to observe live or recorded treatment sessions for reliable and accurate evaluation. This paper describes steps we took to develop a more practical measure of how well providers deliver one EBT, Collaborative Problem Solving (CPS), based on a previously validated measure, to explore whether the quality of the measure can be maintained while reducing the need for training independent observers and the need for recording treatment sessions. This work contributes to the growing efforts of developing more pragmatic fidelity measures and introduces a new tool, the CPS Practice Integrity Form (CPS-PIF), as a promising measure for community-based clinical settings using CPS.

Validation of the "Perrier" parathyroid adenoma location nomenclature.

BACKGROUND: In 2009, the "Perrier" nomenclature was introduced to enhance communications among surgeons and specialists regarding the location of parathyroid adenomas. The purpose of this study was to validate the utility of the nomenclature in a prospective manner at a different institution. METHODS: A prospective database was created from June 2010 through January 2011 evaluating 108 consecutive patients. In each case, the location of the parathyroid adenoma according to the nomenclature was predicted individually by an attending physician and a resident based on preoperative imaging studies. A radiologist interpreted the images retrospectively. These predictions were compared to the operative findings. RESULTS: The mean age of the patients was 61 ± 1 years, and 82% were women. The distribution using the nomenclature was as follows: A (adherent to posterior thyroid capsule) 20%; B (tracheoesophageal groove) 27%; C (tracheoesophageal groove but close to the clavicle) 12%; D (directly over the recurrent laryngeal nerve) 2%; E (easy to identify, inferior thyroid pole) 35%; F (fallen into the thymus) 4%. The overall predicting accuracy was significantly higher for the attending physicians than for the residents or the radiologist (78% vs. 64% vs. 25%, P < 0.001). It was 73-92%, 55-77%, and 12-46%, respectively, for locations with more than four patients. The accuracy was not affected by parathyroid hormone or and calcium levels, or the gland weight. CONCLUSIONS: The "Perrier" nomenclature is reproducible. The most common adenoma locations were B and E in our study, similar to the initial studies. Nevertheless, there is a wide range of preoperative predicting accuracy based on the imaging studies obtained and the interpreter's experience.

Follicular thyroid cancer cell growth inhibition by proteosome inhibitor MG132.

BACKGROUND: Effective therapies for the subset of follicular thyroid cancer (FTC) patients with aggressive, metastatic disease are lacking. Therefore, we sought to determine the effects of proteosome inhibition, an emerging class of chemotherapeutic agents, on metastatic FTC cells. MATERIALS AND METHODS: Human metastatic FTC cells (FTC236) were treated in vitro with the proteosome inhibitor MG132 (0 to 800 nM). Western blot analysis was performed on whole cell lysates isolated after 2 d. To measure cell growth, we performed an MTT cellular proliferation assay over 6 d. RESULTS: Treatment of FTC236 cells with MG132 led to dose-dependent cell growth inhibition. Increases in inactive, phosphorylated GSK-3beta, and active beta-catenin also were observed. With 800 nM MG132, growth was reduced by 87% at 6 d (P < 0.0001). This reduction in cellular proliferation correlated with the degree of GSK-3beta inhibition. MG132 treatment also caused increased p21(Waf1/Cip1) and decreased cyclin D1 expression, suggesting that growth suppression may occur through cell cycle arrest. CONCLUSION: Growth of metastatic human FTC cells appears to be suppressed by proteosome inhibition. Whether this effect is directly due to cell cycle arrest and inactivation of GSK-3beta signaling is unclear. Nonetheless, these compounds may become novel treatments for aggressive, metastatic FTC.

Association of Insurance Status with Severity and Management in ED Patients with Asthma Exacerbation.

INTRODUCTION: Previous studies have demonstrated an association of low socioeconomic status with frequent asthma exacerbations. However, there have been no recent multicenter efforts to examine the relationship of insurance status - a proxy for socioeconomic status - with asthma severity and management in adults. The objective is to investigate chronic and acute asthma management disparities by insurance status among adults requiring emergency department (ED) treatment in the United States. METHODS: We conducted a multicenter chart review study (48 EDs in 23 U.S. states) on ED patients, aged 18-54 years, with acute asthma between 2011 and 2012. Each site underwent training (lecture, practice charts, certification) before reviewing randomly selected charts. We categorized patients into three groups based on their primary health insurance: private, public, and no insurance. Outcome measures were chronic asthma severity (as measured by ≥2 ED visits in one-year period) and management prior to the index ED visit, acute asthma management in the ED, and prescription at ED discharge. RESULTS: The analytic cohort comprised 1,928 ED patients with acute asthma. Among these, 33% had private insurance, 40% had public insurance, and 27% had no insurance. Compared to patients with private insurance, those with public insurance or no insurance were more likely to have ≥2 ED visits during the preceding year (35%, 49%, and 45%, respectively; p<0.001). Despite the higher chronic severity, those with no insurance were less likely to have guideline-recommended chronic asthma care - i.e., lower use of inhaled corticosteroids (ICS [41%, 41%, and 29%; p<0.001]) and asthma specialist care (9%, 10%, and 4%; p<0.001). By contrast, there were no significant differences in acute asthma management in the ED - e.g., use of systemic corticosteroids (75%, 79%, and 78%; p=0.08) or initiation of ICS at ED discharge (12%, 12%, and 14%; p=0.57) - by insurance status. CONCLUSION: In this multicenter observational study of ED patients with acute asthma, we found significant discrepancies in chronic asthma severity and management by insurance status. By contrast, there were no differences in acute asthma management among the insurance groups.

Prevalence of eosinophilia in hospitalized patients with asthma exacerbation.

BACKGROUND: Recent studies have identified the "eosinophilic phenotype" of asthma that is characterized by persistent eosinophilic inflammation and frequent exacerbations. However, the prevalence of eosinophilia in patients hospitalized for asthma exacerbation is not known. METHODS: We performed a pilot study in two sites participating in a multicenter chart review project of children and adults hospitalized for asthma exacerbation during 2012-2013. The pilot study investigated the prevalence of blood eosinophilia in this patient population. Eosinophilia was defined as a count of ≥300 cells/microliter at some time during the hospitalization. RESULTS: Among 80 patients hospitalized for asthma exacerbation, 47 (59%) underwent CBC with differential and had data on blood eosinophil count. These 47 comprised the analytic cohort. The median patient age was 32 years (IQR, 24-44 years), and 51% were female. Overall, 40% (95% CI, 26%-56%) of patients had eosinophilia. Although statistical power was limited, there were no statistically significant differences in patient characteristics or hospital course between patients with eosinophilia and those without (all P > 0.05). CONCLUSION: Our pilot study showed that 40% of patients hospitalized for asthma exacerbation had eosinophilia. The clinical meaning of this biomarker in the emergency department/inpatient setting requires further study in much larger samples with long-term follow-up; such studies appear feasible.

Children and Adults With Frequent Hospitalizations for Asthma Exacerbation, 2012-2013: A Multicenter Observational Study.

BACKGROUND: Earlier studies reported that many patients were frequently hospitalized for asthma exacerbation. However, there have been no recent multicenter studies to characterize this patient population with high morbidity and health care utilization. OBJECTIVE: To examine the proportion and characteristics of children and adults with frequent hospitalizations for asthma exacerbation. METHODS: A multicenter chart review study of patients aged 2 to 54 years who were hospitalized for asthma exacerbation at 1 of 25 hospitals across 18 US states during the period 2012 to 2013 was carried out. The primary outcome was frequency of hospitalizations for asthma exacerbation in the past year (including the index hospitalization). RESULTS: The cohort included 369 children (aged 2-17 years) and 555 adults (aged 18-54 years) hospitalized for asthma exacerbation. Over the 12-month period, 36% of the children and 42% of the adults had 2 or more (frequent) hospitalizations for asthma exacerbation. Among patients with frequent hospitalizations, guideline-recommended outpatient management was suboptimal. For example, among adults, 32% were not on inhaled corticosteroids at the time of index hospitalization and 75% had no evidence of a previous evaluation by an asthma specialist. At hospital discharge, among adults with frequent hospitalizations who had used no controller medications previously, 37% were not prescribed inhaled corticosteroids. Likewise, during a 3-month postdischarge period, 64% of the adults with frequent hospitalizations were not referred to an asthma specialist. Although the proportion of patients who did not receive these guideline-recommended outpatient care appeared higher in adults, these preventive measures were still underutilized in children; for example, 38% of the children with frequent hospitalizations were not referred to asthma specialist after the index hospitalization. CONCLUSIONS: This multicenter study of US patients hospitalized with asthma exacerbation demonstrated a disturbingly high proportion of patients with frequent hospitalizations and ongoing evidence of suboptimal longitudinal asthma care.

Thyroid hormone replacement after thyroid lobectomy.

BACKGROUND: The purpose of this study was to determine the incidence of and identify risk factors for postoperative hypothyroidism in patients undergoing thyroid lobectomy. METHODS: We retrospectively reviewed patients who underwent a thyroid lobectomy for benign disease from May 2004 to December 2007. Patients with known hypothyroidism or on preoperative thyroid hormone replacement were excluded. RESULTS: In this study, 14.3% of patients developed hypothyroidism and required thyroid hormone supplementation. These hypothyroid patients had a higher mean pre-operative thyroid-stimulating hormone (TSH) and lower mean free thyroxine (T4) serum levels compared with euthyroid patients (TSH, 2.12 vs 1.35 microIU/mL [P = .006]; free T4, 1.03 vs 1.34 ng/dL [P = .01]). When stratified into 3 groups based on their preoperative TSH measurement (< or =1.5, 1.51-2.5, and > or =2.51 microIU/mL), the rate of hypothyroidism increased significantly at each level (13.5%, 20.5%, and 41.3%, respectively [P < .001]). In addition, patients with Hashimoto's thyroiditis were significantly more likely to become hypothyroid (odds ratio, 3.78; 95% confidence interval, 2.17-6.60). CONCLUSION: After thyroid lobectomy, approximately 1 in 7 patients experience hypothyroidism requiring thyroid hormone treatment. Patients with preoperative TSH levels >1.5 microIU/mL, lower free T4 levels, and Hashimoto's thyroiditis are at increased risk and should be counseled and followed appropriately.

The UBX-regulated network in the haltere imaginal disc of D. melanogaster.

Hox proteins have been proposed to act at multiple levels within regulatory hierarchies and to directly control the expression of a plethora of target genes. However, for any specific Hox protein or tissue, very few direct in vivo-regulated target genes have been identified. Here, we have identified target genes of the Hox protein Ultrabithorax (UBX), which modifies the genetic regulatory network of the wing to generate the haltere, a modified hindwing. We used whole-genome microarrays and custom arrays including all predicted transcription factors and signaling molecules in the Drosophila melanogaster genome to identify differentially expressed genes in wing and haltere imaginal discs. To elucidate the regulation of selected genes in more detail, we isolated cis-regulatory elements (CREs) for genes that were specifically expressed in either the wing disc or haltere disc. We demonstrate that UBX binds directly to sites in one element, and these sites are critical for activation in the haltere disc. These results indicate that haltere and metathoracic segment morphology is not achieved merely by turning off the wing and mesothoracic development programs, but rather specific genes must also be activated to form these structures. The evolution of haltere morphology involved changes in UBX-regulated target genes, both positive and negative, throughout the wing genetic regulatory network.
