Evaluation of implementation and effect of primary school based intervention to reduce risk factors for obesity

Abstract Objectives: To implement a school based health promotion programme aimed at reducing risk factors for obesity and to evaluate the implementation process and its effect on the school. Design: Data from 10 schools participating in a group randomised controlled crossover trial were pooled and analysed. Setting: 10 primary schools in Leeds. Participants: 634 children (350 boys and 284 girls) aged 7-11 years. Main outcome measures: Response rates to questionnaires, teachers' evaluation of training and input, success of school action plans, content of school meals, and children's knowledge of healthy living and self reported behaviour. Results: All 10 schools participated throughout the study. 76 (89%) of the action points determined by schools in their school action plans were achieved, along with positive changes in school meals. A high level of support for nutrition education and promotion of physical activity was expressed by both teachers and parents. 410 (64%) parents responded to the questionnaire concerning changes they would like to see implemented in school. 19 out of 20 teachers attended the training, and all reported satisfaction with the training, resources, and support. Intervention children showed a higher score for knowledge, attitudes, and self reported behaviour for healthy eating and physical activity. Conclusion: This programme was successfully implemented and produced changes at school level that tackled risk factors for obesity. What is already known on this topic Prevention of obesity is an increasingly important aspect of health promotion Few trials have investigated school based primary prevention programmes directed at obesity What this study adds The programme was successful in producing school level changes to tackle risk factors for obesity High levels of participation indicated support from schools, staff, parents, and pupils Positive changes were seen in school meals, tuck shops, and playground activities
Vasoactive intestinal peptide promotes differentiation and clock gene expression in granulosa cells from prehierarchal follicles

Vasoactive intestinal peptide (VIP) signaling via cyclic adenosine monophosphate (cAMP) is reported to stimulate steroidogenesis in ovarian granulosa cells from a variety of vertebrate species, including the domestic hen. Prior to follicle selection in the hen ovary (i.e., cyclic recruitment) follicle‐stimulating‐hormone (FSH)‐induced cAMP signaling is absent within the granulosa layer until immediately following follicle selection. As a consequence, granulosa cells remain in an undifferentiated state and are unable to initiate FSH‐induced steroidogenesis. VIP receptors (VPAC1 and VPAC2), like the FSH receptor, are G protein‐coupled receptors, so we predicted that VIP signaling in granulosa cells is also absent in follicles that have not yet been selected into the preovulatory hierarchy. Initial studies established that mRNA encoding VPAC1 and VPAC2 are expressed within the granulosa cells throughout follicle development. Nevertheless, undifferentiated granulosa cells from prehierarchal (6–8 mm) follicles do not accumulate cAMP in response to a 4‐hr incubation with chicken VIP; the capacity for such receptor signaling is attained only following selection within actively differentiating granulosa cells. VIP treatment did, however, increase expression of mRNA encoding the Gallus circadian clock protein, BMAL1—but only in granulosa cells collected from selected follicles. These findings provide evidence that, at follicle selection, the acquisition of VIP‐induced cAMP cell signaling helps initiate and promote the differentiation of of granulosa cells. Furthermore, we propose that VIP signaling may regulate BMAL1 expression and, thus, a daily rhythmicity within granulosa cells of preovulatory follicles. Mol. Reprod.

Molecular characterization of acute leukemias by use of microarray technology

Accurate subclassification of leukemia and the identification of prognostic determinants are essential to guide therapy and to improve patients' outcome. According to present standards, pre‐therapeutic assessment depends on a combination of different methods. We aimed to expand the molecular characterization of different acute leukemia subtypes to identify new genome‐wide diagnostic markers. Total RNA from 90 adult patients suffering from acute lymphoblastic leukemia (ALL, n = 25) and acute myeloid leukemia (AML, n = 65) was extracted at diagnosis and high density oligonucleotide microarrays were used to analyze the expression profiles of 12,000/22,000 genes in all specimens (Affymetrix U95Av2/U133A). All cases were thoroughly characterized by individual combinations of cytomorphology, cytogenetics, multiparameter immunophenotyping, and molecular genetics. The expression signature of a small set of differentially expressed genes was sufficient to accurately discriminate eight clinically relevant acute leukemia subgroups. Underlying chromosomal aberrations or immunophenotypical characteristics were strictly correlated with a distinct gene expression pattern for AML with t(8;21), t(15;17), t(11q23)/MLL, or inv(16) as well as for precursor B‐ALL with t(9;22), t(8;14), or t(11q23)/MLL and precursor T‐ALL. These data support a possible future application of microarray technology for classification of the acute leukemias. © 2003 Wiley‐Liss, Inc.
Spinal AMPA receptor inhibition attenuates mechanical allodynia and neuronal hyperexcitability following spinal cord injury in rats

In this study, we examined whether a competitive AMPA receptor antagonist, NBQX, attenuates mechanical allodynia and hyperexcitability of spinal neurons in remote, caudal regions in persistent central neuropathic pain following spinal cord injury in rats. Spinal cord injury was produced by unilateral T13 transverse spinal hemisection, from dorsal to ventral, in male Sprague Dawley rats (200–250 g). Mechanical thresholds were measured behaviorally, and the excitability of wide‐dynamic‐range (WDR) dorsal horn neurons in the lumbar cord (L4–L5) was measured to assess central neuropathicpain. On postoperation day (POD) 28 after spinalhemisection, mechanical thresholds were significantly decreased in both injured (ipsilateral) and noninjured (contralateral) hindpaws compared with preinjury and sham control, respectively (P < 0.05). Intrathecal administration of NBQX (0.25, 0.5, 1 mM) significantly reversed the decreased mechanical thresholds in both hindpaws, dose dependently (P < 0.05). The excitability of WDR neurons was significantly enhanced on both sides of the lumbar dorsal horn 28 days following spinal hemisection (P < 0.05). The hyperexcitability of WDR neurons was attenuated by topical administration of NBQX (0.125, 0.25, 0.5, 1 mM), dose dependently (P < 0.05). Regression analysis indicated that at least three molecules of NBQX bond per receptor complex, and are needed to achieve inhibition of WDR hyperexcitability. In conclusion, our study demonstrates that the AMPA receptor plays an important role in behaviors related to the maintenance of central neuropathic pain below the level of spinal cord injury. © 2007 Wiley‐Liss, Inc.
Low specificity of cytokeratin 19 reverse transcriptase-polymerase chain reaction analyses for detection of hematogenous lung cancer dissemination.

PURPOSE Sensitive detection of systemic tumor dissemination in lung cancer patients is important for selection of appropriate treatment modalities. Based on recent promising data that showed reverse transcriptase-polymerase chain reaction (RT-PCR) analyses for cytokeratin 19 (CK-19) expression in peripheral-blood or bone marrow samples to be a rapid and highly sensitive method for detection of hematogenous tumor dissemination in patients with breast and prostate cancer, we evaluated the specificity of this assay system in lung cancer patients and a large number of healthy controls. PATIENTS AND METHODS We examined CK-19 mRNA expression by RT-PCR in 17 lung cancer cell lines and in peripheral-blood samples of 50 lung tumor patients and 65 healthy controls. RESULTS Expression of CK-19 mRNA was observed in all lung cancer cell lines and in 50% of peripheral-blood samples from lung tumor patients. However, under the experimental conditions analyzed, at least 20% of the control samples were positive for CK-19 mRNA expression. CONCLUSION Contrary to prior reports, RT-PCR may detect non-tissue-specific constitutive low-level (illegitimate) expression of CK-19 mRNA in peripheral-blood mononuclear (PBMN) cells in a significant number of healthy controls. This finding may not only hamper the use of this assay system in lung cancer patients, but also questions its proposed applicability in patients with other epithelial tumors such as breast and prostate cancer.
A Conserved C-terminal Element in the Yeast Doa10 and Human MARCH6 Ubiquitin Ligases Required for Selective Substrate Degradation*

Specific proteins are modified by ubiquitin at the endoplasmic reticulum (ER) and are degraded by the proteasome, a process referred to as ER-associated protein degradation. In Saccharomyces cerevisiae, two principal ER-associated protein degradation ubiquitin ligases (E3s) reside in the ER membrane, Doa10 and Hrd1. The membrane-embedded Doa10 functions in the degradation of substrates in the ER membrane, nuclear envelope, cytoplasm, and nucleoplasm. How most E3 ligases, including Doa10, recognize their protein substrates remains poorly understood. Here we describe a previously unappreciated but highly conserved C-terminal element (CTE) in Doa10; this cytosolically disposed 16-residue motif follows the final transmembrane helix. A conserved CTE asparagine residue is required for ubiquitylation and degradation of a subset of Doa10 substrates. Such selectivity suggests that the Doa10 CTE is involved in substrate discrimination and not general ligase function. Functional conservation of the CTE was investigated in the human ortholog of Doa10, MARCH6 (TEB4), by analyzing MARCH6 autoregulation of its own degradation. Mutation of the conserved Asn residue (N890A) in the MARCH6 CTE stabilized the normally short lived enzyme to the same degree as a catalytically inactivating mutation (C9A). We also report the localization of endogenous MARCH6 to the ER using epitope tagging of the genomic MARCH6 locus by clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9-mediated genome editing. These localization and CTE analyses support the inference that MARCH6 and Doa10 are functionally similar. Moreover, our results with the yeast enzyme suggest that the CTE is involved in the recognition and/or ubiquitylation of specific protein substrates.
Delay of Digital Filter Tuned for Mechanical Resonant Frequency Reduction in Multi-mass Mechanical Systems in Electrical Direct Drive

This paper presents a mathematical model of direct drive system. Includes a four-mass structure for the mechanical part. Discusses how to identify the mechanical resonance frequency using two signals: PRBS (pseudo random binary sequence) and chirp. The result is a nonparametric model from which is determined the resonant frequency. Knowledge of resonance frequencies allows to tune determine digital filter for resonance damping. The filter is inserted between the speed controller and current controller. The article discusses the method of determining the delay caused by the filter. Knowledge of total delay is used in the synthesis of the speed controller. In paper were analyzed following filters: notch, reversed resonance characteristics and low-pass. The exact formulas for the group delay was derived for the notch filter. In the last stage of research the control system was tested. Speed set point was less than 1 res/s.
Binge eating disorder and medical comorbidities in bariatric surgery candidates.

OBJECTIVE To determine whether binge eating disorder (BED) status is associated with medical comorbidities in obese adults scheduled for bariatric surgery. METHOD The study utilized Longitudinal Assessment of Bariatric Surgery-2 data obtained from six clinical centers around the United States. This is a well-phenotyped cohort of individuals who were evaluated within 30 days before their scheduled surgery using standardized protocols. In the cohort, 350 participants were classified as having BED and 1,875 as not having BED (non-BED). Multivariable logistic regression was used to determine whether BED status was independently related to medical comorbidities. As an exploratory analysis, significance was based on nominal p-values (p < .05). Holm's-adjusted p-values were also reported. RESULTS After adjusting for age, sex, education, and body mass index, BED status was found to be independently associated with four of the 15 comorbidities (i.e., impaired glucose levels (odds ratio [OR] = 1.45 (95% confidence interval [CI]: 1.12-1.87)), high triglycerides (OR = 1.28 (95% CI: 1.002-1.63)), and urinary incontinence (OR = 1.30 (95% CI: 1.02-1.66)), all being more common among the BED sample, and severe walking limitations being less common in the BED sample (OR = 0.53 (95% CI: 0.29-0.96)). With further adjustment for psychiatric/emotional health indicators, BED status was independently associated with three comorbidities (impaired glucose levels (OR = 1.36 (95% CI: 1.04-1.79)), cardiovascular disease (OR = 0.50 (95% CI: 0.30-0.86)), and severe walking limitations (OR = 0.38 (95% CI: 0.19-0.77)). However, Holm's-adjusted p-values for all variables were greater than . 05. DISCUSSION The results suggest the possibility of a contribution of BED to risk of specific medical comorbidities in severely obese adults.
Physiological problems in patients undergoing autologous and allogeneic hematopoietic stem cell transplantation

Objective: Stem cell transplantation is usually performed in an effort to extend the patient's life span and to improve their quality of life. This study was conducted to determine the postoperative physiological effects experienced by patients who had undergone autologous and allogeneic stem cell transplantation. Methods: The research is a descriptive study conducted with a sample of 60 patients at Stem Cell Transplantation Units in Ankara. Percentile calculation and chi-square tests were used to evaluate the data. Results: When a comparison was made between patients who had undergone allogeneic Hematopoietic stem cell transplantation (HSCT) and those who had undergone autologous HSCT, results indicated that problems occurred more often for the allogeneic HSCT patients. The problems included: Digestion (94.3%), dermatological (76.7%), cardiac and respiratory (66.7%), neurological (66.7%), eye (56.7%), infections (26.7%) and Graft Versus Host Disease (5 patients). Furthermore, the problems with pain (50%), numbness and tingling (40%), and speech disorders (3 patients) were observed more often in autologous BMT patients. Conclusion: Autologous and allogeneic patients experienced most of physical problems due to they receive high doses of chemotherapy. Therefore, it is recommended that an interdisciplinary support team approach should be usedtohelp reduce and manage the problems that may arise during patient care.
PHYLOGENETIC ANALYSIS OF BREEDING SITE USE AND α‐AMANITIN TOLERANCE WITHIN THE DROSOPHILA QUINARIA SPECIES GROUP

The Drosophila quinaria group is unusual within the genus in that it comprises both mycophagous and nonmycophagous species. DNA sequence data from three regions of the mitochondrial genome were used to infer relationships among four mycophagous species and three that breed on decaying water plants. Phylogenetic analysis of these species show that breeding in mushrooms and tolerance of high levels of α‐amanitin were the ancestral states within the group. Thus, breeding in decaying water plants and intolerance of α‐amanitin are derived conditions. We also found that the D. quinaria species group does not comprise separate mycophagous and nonmycophagous clades, but rather that (1) the shift from mushrooms to decaying plants occurred on at least two occasions; or (2) mycophagy reevolved within a lineage that had previously shifted to breeding on plants. The correlation between mycophagy and α‐amanitin tolerance is perfect across the species we have examined, indicating that there is no detectable time lag between an ecological shift to a new breeding site and correlated changes in biochemical adaptation. The genetic distance between the mycophagous D. recens and the nonmycophagous D. quinaria indicates that these species split only about 1 M.Y. B.P. In terms of α‐amanitin tolerance, D. recens and D. quinaria are typical of other ecologically similar species within the group. Thus, evolutionary changes in α‐amanitin tolerance can evidently occur on the order of about 1 million yr. Our data also indicate that, in comparison to other groups of Drosophila, the quinaria species group may be undergoing an adaptive radiation.
Experimental Errors in QSAR Modeling Sets: What We Can Do and What We Cannot Do

Numerous chemical data sets have become available for quantitative structure–activity relationship (QSAR) modeling studies. However, the quality of different data sources may be different based on the nature of experimental protocols. Therefore, potential experimental errors in the modeling sets may lead to the development of poor QSAR models and further affect the predictions of new compounds. In this study, we explored the relationship between the ratio of questionable data in the modeling sets, which was obtained by simulating experimental errors, and the QSAR modeling performance. To this end, we used eight data sets (four continuous endpoints and four categorical endpoints) that have been extensively curated both in-house and by our collaborators to create over 1800 various QSAR models. Each data set was duplicated to create several new modeling sets with different ratios of simulated experimental errors (i.e., randomizing the activities of part of the compounds) in the modeling process. A fivefold cross-validation process was used to evaluate the modeling performance, which deteriorates when the ratio of experimental errors increases. All of the resulting models were also used to predict external sets of new compounds, which were excluded at the beginning of the modeling process. The modeling results showed that the compounds with relatively large prediction errors in cross-validation processes are likely to be those with simulated experimental errors. However, after removing a certain number of compounds with large prediction errors in the cross-validation process, the external predictions of new compounds did not show improvement. Our conclusion is that the QSAR predictions, especially consensus predictions, can identify compounds with potential experimental errors. But removing those compounds by the cross-validation procedure is not a reasonable means to improve model predictivity due to overfitting.
Serum lipid and apolipoprotein profiles in newborns and six‐year‐old children: The Tallinn Young Family Study

Seventy children aged 6 years (34 boys, 36 girls) were studied for cardiovascular risk factors. Among the children 40 had also been investigated at birth. The aim of the study was to determine changes in serum lipoprotein parameters from birth up to preschool age and to assess the role of some relevant factors that might affect the process. An obvious association was found between serum apolipoprotein (apo) B levels, the apoB/apoA‐I ratio and lipoprotein(a) (Lp(a)) levels at birth and at 6 years of age (r = 0.43; p<0.05, r = 0.73; p<0.0001 and r = 0.81; p<0.0001, respectively). Thirty percent of children who were in the top quartile by apoB or total cholesterol levels and 66.7% of those in this quartile by apoB/apoA‐I ratio at birth remained in the top quartiles also in the follow‐up study. The significantly higher apoB/apoA‐I ratio in newborns and the apoB/apoA‐I and apoB values in the 6‐year‐old children were observed in the carrier apoE4 isoform as compared to E3 homozygotes. A significant influence of apoE polymorphism on serum apoB/apoA‐I ratio and apoB level in preschool children was confirmed by ANOVA one‐way analysis of variance. In a multiple regression analysis from all the studied factors, the independent determinants of apoB level in preschool age were apoE phenotype, gestational age and Apgar score in the first minute of life. Thus, tracking of serum Lp(a), apoB, apoB/apoA‐I ratio and total cholesterol levels from birth up to 6 years of age was demonstrated. The association between apoE polymorphism and serum lipoprotein parameters became more obvious after the first 6 years of life.
Reliability of two methods for measurement of alveolar bone level in children.

OBJECTIVES To determine the intra- and interexaminer reliability of two methods (calliper and computerized images) for measuring the alveolar bone level on bitewing radiographs of pre-school children and to determine the extent to which one method can measure more sites. METHODS Standardized paediatric bitewings were analysed with either an image analysis program (ImageTool) or a digital calliper (Digimatic Caliper). With each method, radiographs were measured three times by three trained examiners. The differences in the number of sites measured with the two methods were assessed with McNemar's tests and kappa statistics. Reliability was assessed with paired t-tests, intraclass correlation coefficients (ICCs), Bland-Altman and survival-agreement plots. RESULTS The kappa statistics and McNemar's test indicated that examiners measured 14% fewer sites using ImageTool. Paired t-tests also demonstrated a statistically significant bias (range 0.11-0.23 mm) indicating larger measurements for this method, although these observed differences were considered clinically unimportant for the detection of 2 mm of bone loss (which was considered the threshold for periodontal disease). Intra- and interexaminer reliability (ICC range: 0.87-0.97) was considered good for both methods. CONCLUSIONS Reliable methods to assess alveolar bone loss in primary teeth are important for the diagnosis of incipient periodontal diseases. Both studied methods proved to be reliable. With the Digimatic Caliper, however, more sites were measured.
In Situ Detection of Epstein‐Barr Virus in Gastric and Colorectal Adenocarcinomas

The association of Epstein-Barr virus (EBV) with lymphoepithelioma-like carcinoma in the nasopharynx, which is common in Chinese from the southern region, is well established. Recently, EBV has also been found to be associated with lymphoepithelioma-like carcinomas (LELCs) and carcinomas with prominent lymphoid infiltrates in the stomach. We investigated for the presence of EBV in 74 cases of gastric adenocarcinoma and 36 cases of colorectal adenocarcinoma from Chinese patients by in situ hybridization (ISH) using an antisense EBER probe. In seven cases (9.5%) of gastric carcinoma, EBER was highly expressed in the adenocarcinoma cells and metastatic tumor cells in regional lymph nodes. In all these cases, the normal gastric epithelium was EBV negative. None of the colorectal carcinomas showed a positive signal. Isolated positive lymphoid cells were frequently found in both tumors. Of the seven positive cases, only one was LELC, and the others were conventional adenocarcinomas of the intestinal type. Five showed expression of the viral RNA in all tumor cells as well as the surrounding dysplastic epithelium. Interestingly, the sixth case showed distinct negative islands of dysplastic glands adjacent to strongly positive dysplastic glands and invasive carcinoma cells. This pattern of positivity, together with negative normal gastric epithelium and positive metastatic tumor, suggested that EBV infection occurred in the dysplastic phase and that an apparent growth advantage was conferred by the EBV infection.
