The 'best fit' endotracheal tube in children --comparison of four formulae.

BACKGROUND Uncuffed endotracheal tubes are still being recommended by most pediatric of anesthetists at our Institutes. Different algorithms and formulae have been proposed to choose the best-fitting size of the tracheal tube. The most widely accepted is related to the age of the child [inner diameter [ID] in mm = (age in yr/4) + 4; the second is a body, length-related formula (ID in mm = 2 + height in cm/30); the third, a multivariate formula (ID in mm = 2.44 + age in yr x 0.1 + height in cm x 0.02 + weight in kg x 0.016]5; the fourth, the width of the 5th fingernail is used for ID prediction of the ETT (ID in mm = maximum width of the 5th fingernail). The primary endpoint of this prospective study was to compare the size of the 'best fit' tracheal tube with the size predicted using each of the above mentioned formulae. PATIENTS AND METHODS With Institutional Ethics Committee approval and parental consent, 27 boys, 23 girls, ASA I-III, 2-10 years, scheduled for different surgical procedures requiring general anesthesia and endotracheal intubation, were enrolled in the study. The size of 'best fit' endotracheal tubes in those children were compared. The internal diameter considered the 'best fit' by the attending pediatric anesthesiologist was compared to age-based, length-based, multivariate-based and 5th fingernail width-based formulae. For all tests, P < 0.05 was considered to be statistically significant. RESULTS The mean (SD) IDs for the 'best fit', age-based, length-based, multivariate and 5th fingernail techniques were 5.31 (0.691), 5.54 (0.622), 5.82 (0.572), 5.71 (0.67) and 5.43 (0.821) mm, respectively. CONCLUSIONS The age-based and 5th fingernail width-based predictions of ETT size are more accurate than length-based and multivariate-based formulae in terms of mean value and case matching.
Evaluation of Outcome of Orthodontic Treatment in Context to Posttreatment Stability: A Retrospective Analysis.

INTRODUCTION One of the main aims of orthodontic treatment is the improvement of esthetics along with enhancement of functions of the orofacial regions. Complications are observed even after final completion of the orthodontic treatment due to relapse and loss of stability. Hence, we retrospectively analyzed angle class I malocclusion cases to study the correlation of outcome of orthodontic treatment and posttreatment stability. MATERIALS AND METHODS A total of 100 patients were included in this retrospective analysis, which accounted for the patients reporting to the department of orthodontics from 2013 to 2015 with angle class I malocclusion. Pretreatment, posttreatment, and postretention casts of the patients were made and analyzed. The Richmond et al criteria was used to evaluate peer assessment rating (PAR) index and Little irregularity index, followed by scoring with American weight. Measurement of Pearson's coefficient was done to calculate the p-value. p-value of less than 0.05 was considered as significant. RESULTS No significant amount of alteration was seen in the systematic errors of Little index and PAR index, while casual errors were also within the normal range. While comparing the PAR index at pretreatment and posttreatment phases, statistically significant results were obtained, whereas in case of Little index at same time intervals, scores showed nonsignificant results. CONCLUSION Even after delivering ideal orthodontic treatment, stability of the treatment is still not ensured until unless posttreatment follow-up is properly maintained.
Amelogenin Exons 8 and 9 Encoded Peptide Enhances Leucine Rich Amelogenin Peptide Mediated Dental Pulp Repair

Amelogenins containing exons 8 and 9 are alternatively spliced variants of amelogenin. Some amelogenin spliced variants have been found to promote pulp regeneration following pulp exposure. The function of the amelogenin spliced variants with the exons 8 and 9 remains unknown. In this study, we synthesized recombinant leucine rich amelogenin peptide (LRAP, A–4), LRAP plus exons 8 and 9 peptide (LRAP 8, 9) or exons 8 and 9 peptide (P89), to determine their effects on odontoblasts. In vivo analyses were completed following the insertion of agarose beads containing LRAP or LRAP 8, 9 into exposed cavity preparations of rat molars. After 8, 15 or 30 days’ exposure, the pulp tissues were analyzed for changes in histomorphometry and cell proliferation by PCNA stainings. In vitro analyses included the effects of the addition of the recombinant proteins or peptide on cell proliferation, differentiation and adhesion of postnatal human dental pulp cells (DPCs). These studies showed that in vivo LRAP 8, 9 enhanced the reparative dentin formation as compared to LRAP. In vitro LRAP 8, 9 promoted DPC proliferation and differentiation to a greater extent than LRAP. These data suggest that amelogenin exons 8 and 9 may be useful in amelogenin-mediated pulp repair.
Oral health status in relation to ethnicity of children in the Municipality of Copenhagen, Denmark.

UNLABELLED Approximately 25% of children under the age of 18 in the Municipality of Copenhagen have a non-Danish ethnic background, and it is suspected that there may be major inequalities in oral health as a result. OBJECTIVES The objectives of this study were to describe the occurrence of dental caries in different ethnic minorities, and to analyse whether the dental caries experience of the children may be affected by cultural and behavioural differences. MATERIALS AND METHODS The study was conducted in Copenhagen as a cross-sectional investigation of 794 children, aged 3 and 5 years old (preschool), 7 years old (Grade 1) and 15 years old (Grade 9). Children of Danish, Turkish, Pakistani, Albanian, Somali and Arabian backgrounds were selected by convenience sampling. Epidemiological data were retrieved from the Danish Recording System for the Public Dental Health Services (SCOR) and sociological data were collected by postal questionnaires. RESULTS Marked differences in dental caries prevalence were observed when different ethnic minorities were compared to Danish children. These were most prominent for the primary dentition. At age 7, 53% of the Danish and 84% of the Albanian children were affected by dental caries, the mean caries experience was 3.5 dmfs (decayed, missed and filled surfaces) and 13.8 dmfs, respectively. Caries in incisors and/or smooth surfaces was observed in 10% of the Danish children and 48% of the Albanian children. There were cultural differences in dental attendance and self-care practices of children and parents. These socio-behavioural factors may help to explain the differences in dental caries prevalence and severity. CONCLUSIONS Development of appropriate oral health promotion strategies is urgently needed to improve oral health behaviour and attitudes of parents and children of ethnic minorities. Preventive programs should be organized at local community level in close collaboration with key persons of ethnic minority societies.
The neuropeptide head activator is a high-affinity ligand for the orphan G-protein-coupled receptor GPR37

The neuropeptide head activator (HA) is a mitogen for mammalian cell lines of neuronal or neuroendocrine origin. HA signalling is mediated by a G-protein-coupled receptor (GPCR). Orphan GPCRs with homology to peptide receptors were screened for HA interaction. Electrophysiological recordings in frog oocytes and in mammalian cell lines as well as Ca2+ mobilisation assays revealed nanomolar affinities of HA to GPR37. HA signal transduction through GPR37 was mediated by an inhibitory G protein and required Ca2+ influx through a channel of the transient receptor potential (TRP) family. It also required activation of Ca2+-dependent calmodulin kinase and phosphoinositide 3-kinase. Respective inhibitors blocked HA signalling and HA-induced mitosis in GPR37-expressing cells. HA treatment resulted in internalisation of GPR37. Overexpression of GPR37 led to aggregate formation, retention of the receptor in the cytoplasm and low survival rates of transfected cells, confirming the notion that misfolded GPR37 contributes to cell death, as observed in Parkinson's disease.
INTERGENIC SPACER (IGS) POLYMORPHISM: A NEW GENETIC MARKER FOR DIFFERENTIATION OF TOXOPLASMA GONDII STRAINS AND NEOSPORA CANINUM

The region between the 28S and 18S rRNA genes, including the intergenic spacer (IGS) region and the 5S rRNA gene, from 32 strains of Toxoplasma gondii and the NC1 strain of Neospora caninum was amplified and used for DNA sequencing and/or restriction fragment length polymorphism (RFLP) analysis. The 5S rDNA sequences from 20 strains of T. gondii were identical. The IGS region between the 5S and 18S rRNA genes (nontranscribed spacer 2 or NTS 2) showed 10 nucleotide variations. Six of the 10 variant positions correlated with the murine virulence of the strains. Intraspecific polymorphisms distinguished the virulent strains of zymodemes 5, 6, and 8 from other virulent strains (in zymodeme 1). RFLP methods (IGS-RFLP) were developed and used to characterize the virulent and avirulent patterns among 29 T. gondii strains. Sequence diversity of 19.8% was found between T. gondii and N. caninum when comparing a region of 919 bp at the 3′ end of NTS 2. The sequence variation in ribosomal IGS could therefore be a useful marker for Toxoplasma strain identification and for distinguishing N. caninum from T. gondii.
Syntactic and Story Structure Complexity in the Narratives of High- and Low-Language Ability Children with Autism Spectrum Disorder

Although language impairment is commonly associated with the autism spectrum disorder (ASD), the Diagnostic Statistical Manual no longer includes language impairment as a necessary component of an ASD diagnosis (American Psychiatric Association, 2013). However, children with ASD and no comorbid intellectual disability struggle with some aspects of language whose precise nature is still outstanding. Narratives have been extensively used as a tool to examine lexical and syntactic abilities, as well as pragmatic skills in children with ASD. This study contributes to this literature by investigating the narrative skills of 30 Greek-speaking children with ASD and normal non-verbal IQ, 16 with language skills in the upper end of the normal range (ASD-HL), and 14 in the lower end of the normal range (ASD-LL). The control group consisted of 15 age-matched typically-developing (TD) children. Narrative performance was measured in terms of both microstructural and macrostructural properties. Microstructural properties included lexical and syntactic measures of complexity such as subordinate vs. coordinate clauses and types of subordinate clauses. Macrostructure was measured in terms of the diversity in the use of internal state terms (ISTs) and story structure complexity, i.e., children's ability to produce important units of information that involve the setting, characters, events, and outcomes of the story, as well as the characters' thoughts and feelings. The findings demonstrate that high language ability and syntactic complexity pattern together in ASD children's narrative performance and that language ability compensates for autistic children's pragmatic deficit associated with the production of Theory of Mind-related ISTs. Nevertheless, both groups of children with ASD (high and low language ability) scored lower than the TD controls in the production of Theory of Mind-unrelated ISTs, modifier clauses and story structure complexity.
Factors affecting the palpability of breast lesion by self-examination.

INTRODUCTION This study aims to assess the accuracy of detection of breast lesion by breast self-examination and to assess different factors affecting the accuracy. METHODS All consecutive Chinese female patients, who attended our breast imaging unit in 2001, completed our questionnaire, had retrievable hard copy films, and had more than three years clinical follow-up, were recruited for this study. Different factors, such as age, menopausal status, previous experience of breastfeeding, family history of breast cancer, previous history of mastectomy or lumpectomy, hormonal therapy, oral contraceptive pills and previous history of mammography, were correlated with accuracy in self-detection of breast lesions retrospectively. The nature, size and location of the lesion, and breast size based on imaging, were also correlated with the accuracy in self-detection of breast lesions. RESULTS A total of 163 questionnaires were analysed. 111 patients detected a breast lesion themselves and 24 of these lesions were false-positives. A total of 173 lesions (27 cancerous, 146 benign lesions) were documented by either ultrasonography and/or mammography, and confirmed by either histology or three-year clinical follow-up. The overall sensitivity in detecting both benign and malignant breast lesions was 71% when number of breast lesions was used as the denominator, and up to 78% sensitivity was achieved when number of patients was used as the denominator. History of mastectomy, and size and nature of the lesions were found to affect the accuracy of self-detection of breast lesions. CONCLUSION Overall, breast self-examinations were effective in the detection of breast lesions and factors such as size of lesion, nature of the lesion and history of mastectomy affect the accuracy of the detections. Breast self-examination should be promoted for early detection of breast cancer.
Weed control in rose-scented geranium (Pelargonium spp).

Abstract: Field investigations were carried out during 1999 and 2000 to identify effective chemical/ cultural methods of weed control in rose-scented geranium (Pelargonium spp). The treatments comprised pre-emergence applications of oxyfluorfen (0.15, 0.20 and 0.25 kg AI ha(-1)) and pendimethalin (0.50, 0.75 and 1.00kg AI ha(-1)), successive hand weeding, hoeing and mulching using spent of lemon grass (at 5 tonnes ha(-1)) 45 days after planting (DAP), three hand-weedings 30, 60 and 90 DAP, weed-free (frequent manual weeding) and weedy control. Broad-leaf weeds were more predominant than grass and sedge weeds, accounting for 85.8% weed density and 93.0% weed dry weight in 1999 and 77.2% weed density and 93.9% weed dry weight in 2000. Unrestricted weed growth significantly reduced geranium oil yield, by 61.6% and 70.6% in 1999 and 2000, respectively. Pre-emergence application of pendimethalin (0.75-1.00 kgAI ha(-1)) or oxyfluorfen (0.25 kg AI ha(-1)), successive hand-weeding, hoeing and mulching and three hand-weedings were highly effective in reducing weed density and dry weight and gave oil yield comparable to the weed-free check. Application of oxyfluorfen (0.15 or 0.20 kg AI ha(-1)) and pendimethalin (0.50 kg AI ha(-1)) were less effective in controlling the weed species in geranium. None of the herbicides impaired the quality of rose-scented geranium oil measured in terms of citronellol and geraniol content.
Gender differences in the utilisation of surgery for congenital heart disease in India

Background Corrective surgery for congenital heart disease may be life-saving, but its utilisation depends upon several social and economic factors. Girls with cardiac defects may not receive equitable care in India, but this has not been systematically studied. Methods In this prospective study, parents or guardians of 405 consecutive children aged up to 12 years (mean±SD age 3.43±3.44 years; 271 boys) who had been advised to undergo elective paediatric cardiac surgery were interviewed using a validated questionnaire. The status of the patients was reviewed after a year and the factors associated with non-compliance with treatment were analysed. In a qualitative sub-study the parents of 20 children who had not undergone surgery were interviewed. Qualitative data were analysed using an inductive analytical approach. Results Of the 405 patients studied, 44% (59/134) of girls had undergone surgery at 1 year compared with 70% (189/271) of boys (χ2=24.97; p<0.001). Independent predictors for non-compliance with surgery included female gender (OR 3.46, 95% CI −2.06 to 5.80; p<0.0001), lower socioeconomic classes (lower-middle: OR 18.62, 95% CI −2.14 to 161.8, p=0.008; upper-lower: OR 34.27, 95% CI −3.72 to 316.0, p=0.002) and higher cost of surgery (OR 1.92, 95% CI −1.06 to 3.47, p=0.03). In the in-depth interviews, apprehensions about future matrimonial prospects of girls and lack of social support emerged as the major factors responsible for delays in undergoing surgery. Conclusions Female gender is an important determinant of non-compliance with paediatric cardiac surgery. Deep-seated social factors underlie this gender bias.
The conceptual framework of the factors influencing consumer satisfaction in social commerce

The twentieth century has seen enormous changes in the field of Information Communication Technology (ICT) and that change will continue into the future, as well. When Web 2.0 tools appeared, people had the opportunity to interact with each other on the internet and helped to create a new stream with different functions. This stream called Social commerce (SC) which is defined as an extension of Business to Customer (B2C) e-commerce where consumers can interact with each other to conduct online shopping activities and discuss their experiences and preferences on products and services. Virtually all of the previous research on SC focus on behavioral and purchase intentions. In addition, there are many theories that can provide a better understanding of the satisfaction in SC. For instance, the theory of social interaction (Liang & Turban 2011) and the theory of social process (Amblee & Bui 2011) can both help in understanding consumer behaviors. In addition, the motivation theory might help in understanding why people use SC as well as how intrinsic and extrinsic motivations carry on in SC (Liang & Turban 2011). Although these studies have reviled promising findings, questions remain concerning what factors affect consumers’ satisfaction, which are yet to be answered. Therefore, this study aims to develop a theoretical framework using Trust and Social Influence theories to investigate the influencing factors on customer satisfaction in social commerce. Investigating the theoretical framework of this study would provide theoretical evidence and help businesses and individuals to better understanding the factors that affect consumer satisfaction in SC.
Metabolic Response to Feeding in Tupinambis merianae: Circadian Rhythm and a Possible Respiratory Constraint

The diurnal tegu lizard Tupinambis merianae exhibits a marked circadian variation in metabolism that is characterized by the significant increase in metabolism during part of the day. These increases in metabolic rate, found in the fasting animal, are absent during the first 2 d after meal ingestion but reappear subsequently, and the daily increase in metabolic rate is added to the increase in metabolic rate caused by digestion. During the first 2 d after feeding, priority is given to digestion, while on the third and following days, the metabolic demands are clearly added to each other. This response seems to be a regulated response of the animal, which becomes less active after food ingestion, rather than an inability of the respiratory system to support simultaneous demands at the beginning of digestion. The body cavity of Tupinambis is divided into two compartments by a posthepatic septum (PHS). Animals that had their PHS surgically removed showed no significant alteration in the postprandial metabolic response compared to tegus with intact PHS. The maximal metabolic increment during digestion, the relative cost of meal digestion, and the duration of the process were virtually unaffected by the removal of the PHS.
Mutations in the ataxia telangiectasia and rad3‐related–checkpoint kinase 1 DNA damage response axis in colon cancers

In response to certain types of DNA damage, ataxia telangiectasia and rad3‐related (ATR) phosphorylates checkpoint kinase 1 (CHEK1) resulting in cell cycle arrest and subsequent DNA repair. ATR and CHEK1 contain mononucleotide microsatellite repeat regions, which are mutational targets in tumors with defective mismatch repair (MMR). This study examined the frequency of such mutations in colon cancers and their impact on biologic behavior. Screening for ATR mutations in 48 tumors was performed using denaturing high‐performance liquid chromatography (DHPLC) and confirmed with sequencing analysis. The CHEK1 exon 7 A(9) region was sequenced in 20 of the 27 (74%) tumors with high frequency of microsatellite instability (MSI‐H). Univariate and multivariate analyses were used to examine associations with clinical outcomes. Frequent mutations in MSI‐H colon cancers were identified within the ATR (37%)/CHEK1(5%) damage response pathway. Stage and MSI status both independently predicted overall survival (OS) and disease‐free survival (DFS). ATR status was not associated with stage, but was associated with a trend toward improved DFS: 0/9 cancers recurred in MSI‐H cases harboring ATR mutations vs. 4/18 recurrences in MSI‐H cases without ATR mutations. This suggests that ATR mutations may affect clinical behavior and response to therapy in MSI‐H colon cancers. © 2007 Wiley‐Liss, Inc.
Artesunate, artemether or quinine in severe Plasmodium falciparum malaria?

Quinine and the artemisinin-derivative drugs artesunate and artemether are effective treatments for severe falciparum malaria. Trials comparing artemether with quinine have not demonstrated convincing evidence of a mortality advantage for artemether. The South East Asian Quinine Artesunate Malaria Trial (SEAQUAMAT), a multicenter, randomized, open-label trial in 1461 adults with severe malaria in Asia compared artesunate with quinine. Mortality was 15% in the artesunate group and 22% in the quinine group, a reduction of 34.7% (95% confidence interval: 18.5–47.6%) in the artesunate group, with almost all the benefit reported in those with high parasite counts. Artesunate should constitute first-line treatment for severe malaria in Asia. These results can probably be generalized to the treatment of severe malaria in adults from all areas, especially in those with hyperparasitemia. However, it is unclear whether these results can be generalized to children in Africa, who constitute the majority of those who die from severe malaria worldwide.
Outcome of a Food Observational Study Among Low-Income Preschool Children Participating in a Family-Style Meal Setting

Introduction. In the United States, one out of every seven low-income children between the ages of 2 and 5 years is at risk for overweight and obesity. Formative research was conducted to determine if preschool children participating in family-style meals consumed the minimum food servings according to U.S. Department of Agriculture dietary guidelines. Method. Participants were 135 low-income children aged 3 to 4 years who attended an urban child care center. Participant’s parents completed a Family Demographic Questionnaire to provide information on race/ethnicity, parent’s level of education, and household income. Direct observation of children’s food and beverage consumption during school breakfast and lunch was collected over 3 consecutive days. Dietary data were assessed using the Nutrition Data System for Research software. Height and weight measurements were obtained to determine risk for obesity. Descriptive statistics were reported by using the Statistical Package for the Social Sciences Version 16. Results. Among 135 participants, 98% identified as Mexican American, 75% lived at or below poverty level, and 24% reported a family history of diabetes. Children consumed less than half of the calories provided between breakfast and lunch and did not consume the minimum recommended dietary food servings. Despite the poor dietary intake, physical measurement findings showed 25% obesity prevalence among study participants. Conclusions. Findings support the need for evidenced-based early childhood obesity prevention programs that provide behavior change opportunities for children, their families, teachers, and menu planners. Family-style meal settings are ideal opportunities for implementing nutrition education strategies to prevent early childhood obesity.
