Validation of the short version of the dimensional inventory for child development assessment

Objectives: There is a critical need to monitor the development of children around the world, and in Brazil, this need is substantial since there is a paucity of assessment tools. This study aimed to describe the design and provide evidence of reliability and validity for the short version of the Dimensional Inventory for Child Development Assessment (IDADI-short). Methods: A sample of 1,865 biological mothers of children aged 4---72 months (M = 34.8, SD = 20.20) completed the IDADI to assess Cognitive, socio-emotional, Expressive, and Receptive Language and Communication, Fine and Gross Motor, and Adaptive Behavior development. The psychometric properties of a total of 118 subscales of IDADI were obtained and the IDADI-short age-specific scores were correlated with the original inventory, and criteria variables such as neurodevelopment diagnosis, socioeconomic status, and sex. Results: Item Response Theory analysis, Cronbach’s Alpha, and McDonald’s Omega indicated excellent internal consistency and optimal participant discrimination after minor alterations. IDADI-short scores were strongly associated with the original inventory, with high sensibility and specificity precision for developmental delays. Significant associations with relevant criteria variables were also observed. Conclusion: Findings support the use of IDADI-short as a parental measure of young children’s development

Cardiorespiratory andmetabolic responses and reference equation validation to predict peak oxygen uptake for the incremental shuttle waking test in adolescent boys

Background Previous studies speculated that the Incremental Shuttle Walking Test (ISWT) is a maximal test in children and adolescents, however comparison between ISWT with cardiopulmonary exercise test has not yet performed. Furthermore, there is no regression equation available in the current literature to predict oxygen peak consumption (VO2 peak) in this population. This study aimed to assesses and correlate the cardiorespiratory responses of the ISWT with the cardiopulmonary exercise (CEPT) and to develop and validate a regression equation to predict VO2 peak in healthy sedentary adolescent boys. Methods Forty-one participants were included in the study. In the first stage, the VO2 peak, respiratory exchange ratio (R peak), heart rate max (HR max) and percentage of predicted HR max (% predicted HR max) were evaluated in CEPT and ISWT (n = 26). Second, an equation was developed (n = 29) to predict VO2 peak. In both phases, the VO2 peak, respiratory exchange ratio R and hearth rate (HR) were evaluated. In the third stage, the validation equation was performed by another 12 participants. Results Similar results in VO2 peak (P>0.05), R peak (P>0.05) and predicted maximum HR (P>0.05) were obtained between the ISWT and CEPT. Both tests showed moderate significant correlations of VO2 peak (r = 0.44, P = 0.002) e R peak (r = -0.53, P < 0.01), as well as the agreement of these measurements by Bland-Altman analysis (VO2 peak, bias = -0.13; R peak, bias = 0.0). Distance walked was the variable that explained 42.5% (R2 = 0.425, p = 0.0001) of the variance in VO2 peak. The equation was VO2 peak (predicted) = 20.94 + (0.02 x distance walked). The results obtained by the equation were not significantly different compared to the values obtained by the gas analyzer and the Bland-Altman analysis showed agreement (bias = 1.6). Conclusion The ISWT produced maximal cardiorespiratory responses comparable to the CEPT, and the developed equation showed viability for the prediction of VO2 peak in healthy sedentary adolescent boys.Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico (CNPq)Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES)Funda??o de Amparo ?

Automotive Turbocharger Compressor CFD and Extension Towards Incorporating Installation Effects

This paper focuses on the application of CFD to turbocharger compressor characteristics predictions over a range of speeds between 100,000 and 200,000RPM, and concentrating around the peak performance at 160,000RPM. A production turbocharger compressor which is widely used in the small-to-medium size automotive sector is studied. A methodical approach is taken to compare computation versus rig measurements, which represents an idealised installation. Benchmarking under the idealised rig conditions then gives a degree of confidence to apply the same prediction method to the device under real installation conditions. In practice this means that the inlet duct is strongly curved due to space constraints. One observes that the performance of the compressor deteriorates at higher mass flows when the inflow to the compressor face is distorted by a curvilinear duct. Under the same installation constraint, we then observe that performance reduces when using inlet guide vanes upstream of the compressor face to alleviate noise problems. A primary motivator in this work is to develop an efficient methodology for analysing the turbocharger compressor performance. To do this it is necessary first to benchmark the CFD methodology in steady-state so that the OEM can be confident to perform intake design analyses for their vehicles under installation conditions. Therefore we concentrate here on robust processes for geometry handling, meshing and flow solution which can be easily automated.</jats:p

Autism Spectrum Disorder: An Overview of Early Detection, and Role of Nurses

Autism spectrum disorder ASD is a neurological and developmental illness that affects social relationships and communication as well as a variety of challenging behaviors. Children are not screened for ASD despite the fact that it is generally recommended. The best outcomes for people with ASD come from early intervention and developmental surveillance and screening are essential before intervention. Nurses are the primary healthcare providers for children and they are in a unique position to encourage their development. They have regular contact with children before they start school and can deliver family-centered comprehensive coordinated care including a more thorough medical assessment if a screening suggests a child is at risk for a developmental condition. The diagnosis of ASD is on the continual rise usually diagnosed in the younger years of life but this is not always the case. Regardless of when the diagnosis is received it is important to remember that individuals diagnosed with ASD continue to grow into adulthood and experience many of the same illnesses and disorders as the rest of society thus rendering the nurse the possibility of interacting with this special population sometime throughout his or her career.</jats:p

Breast Adenocarcinoma Mimicking Temporomandibular Disorders: A Case Report

Aim: The aim of this report is to present a case of a metastatic lesion in the mandible originating from a breast adenocarcinoma that was initially diagnosed as temporomandibular disorder (TMD). The role of the dental practitioner in the diagnostic phases is also discussed. Background: It is not uncommon to see a patient who complains of what seems to be a TMD but who in reality suffers from a systematic disease, dental infection, or neoplasia. Although metastases to the head and neck are uncommon, it should always be considered among the differential diagnoses of lesions. Report: A 42-year-old female presented with pain and swelling in the right temporomandibular joint (TMJ) previously diagnosed as TMD. Further clinical, radiological, and histological examinations coupled with a history of adenocarcinoma of the breast lead to a final diagnosis of a metastatic lesion in the right TMJ region. Summary: In most patients who present with an oral metastasis the distant primary tumor has already been diagnosed and treated. Occasionally the discovery of an oral metastasis leads to the detection of an occult primary malignancy elsewhere in the body. Thus the dentist should be able to perform an adequate diagnosis and play an important role in the diagnostic phase of care that can lead to a useful palliation and an enhanced quality of the patient's life. Clinical Significance: In order to avoid the pitfalls so common in evaluating patients with TMJ pain, the clinician must perform a complete and critical review of the medical history along with a comprehensive examination. The challenge is to know and evaluate the differential diagnosis. Failure to do so can result in a misdiagnosis which may lead to unnecessary care, long-term therapy without clinical resolution, or potentionally death.95100106Bodner, L., Sion-Vardy, N., Geffen, D.B., Nash, M., Metastatic tumors to the jaws: A report of eight new cases (2006) Med Oral Patol Oral Cir Bucal, 11 (2), pp. E132-E135van der Waal, R.I., Buter, J., van der Waal, I., Oral metastases: Report of 24 cases (2003) Br J Oral Maxillofac Surg, 41 (1), pp. 3-6Ogutcen-Toller, M., Metin, M., Yildiz, L., Metastatic breast carcinoma mimicking periodontal disease on radiographs (2002) J Clin Periodontol, 29 (3), pp. 269-271Adelson, R.T., DeFatta, R.J., Miles, B.A., Hoblitt, S.L., Ducic, Y., Metastatic breast cancer of the oral cavity (2005) Am J Otolaryngol, 26 (4), pp. 279-281Keller, E.E., Gunderson, L.L., Bone disease metastatic to the jaws (1987) J Am Dent Assoc, 115 (5), pp. 697-701Johal, A.S., Davies, S.J., Franklin, C.D., Condylar metastasis: A review and case report (1994) Br J Oral Maxillofac Surg, 32 (3), pp. 180-182Ozcelik, T.B., Ersoy, A.E., Temporomandibular joint clicking noises caused by a multilocular bone cyst: A case report (2006) J Contemp Dent Pract, 7 (3), pp. 99-105Auriol, M., Chomette, G., Wann, A., Guilbert, F., Metastases of malignant tumor in the jaw.

Knowledge Based Methodology Supporting Interoperability Increase in Manufacture Domain

The formation of cooperation and collaboration alliances between several small organizations is proving, in multiple cases, to be more efficient and competitive by comparison with big companies. Manufacturing processes span nowadays across borders as result of the globalization markets pressure, thus research on manufacturing management has turned from an intra-enterprise to an inter-enterprise focus. Consequently there is a growing interest in electronic business (e-business) solutions to facilitate information sharing between organizations in the supply chain. However, due to the worldwide diversity of communities, a high number of knowledge representation elements, such as ontologies, which are not semantically coincident, have appeared representing the same segment of reality. Even operating in the same domain, enterprises do not understand each other, making the communication among various systems parties more difficult and sometimes impracticable. As a result there is a demand for intelligent solutions capable of reinforcing partnerships and collaborations between enterprises, which needs to be able to manage its maintenance dynamically. Authors propose the increase of Interoperability in the mechanical manufacturing domain by the use of a knowledge–based methodology able to build a reference ontology and to provide its maintenance through the system user’s feedback.</jats:p
