Environmental opportunities facilitating cognitive development in preschoolers: development of a multicriteria index.

Access to environmental opportunities can favor children's learning and cognitive development. The objectives is to construct an index that synthesizes environmental learning opportunities for preschoolers considering the home environment and verify whether the index can predict preschoolers' cognitive development. A quantitative, cross-sectional, exploratory study was conducted with 51 preschoolers using a multi-attribute utility theory (MAUT). The criteria used for drawing up the index were supported by the literature and subdivided in Group A "Resources from the house" extracted from HOME Inventory including: (1) to have three or more puzzles; (2) have at least ten children's books; (3) be encouraged to learn the alphabet; (4) take the family out at least every 2 weeks. Group B "Screens" (5) caution with using television; (6) total screen time in day/minutes. Group C "Parental Schooling" (7) maternal and paternal education. Pearson correlation analyses and univariate linear regression were performed to verify the relationship between the established index with cognitive test results. The index correlated with the total score of the mini-mental state exam (MMC) and verbal fluency test (VF) in the category of total word production and word production without errors. Multicriteria index explained 18% of the VF (total word production), 19% of the VF (total production of words without errors) and 17% of the MMC. The present multicriteria index has potential application as it synthesizes the preschooler's environmental learning opportunities and predicts domains of child cognitive development.

Do Signs of Attention-Deficit/Hyperactivity Disorder Increase the Odds of Dental Caries? A Case-Control Study.

Attention-deficit/hyperactivity disorder (ADHD) is a behavioural disorder that can affect one's performance in activities of daily living and can exert a negative impact on the oral health of children. OBJECTIVE: The aim of this work was to determine the association between ADHD (signs and executive functions) and dental caries in children aged 7-12 years. METHODS: A case-control study was conducted with 532 children in the city of Diamantina, Brazil. The case group was composed of children with caries and the control group was composed of children without caries. The children were submitted to a clinical oral examination for the determination of caries and neuropsychological evaluations of intellectual function and executive function. Other signs of attention deficit and hyperactivity were investigated using the Swanson, Nolan, and Pelham scale administered to parents/guardians and teachers. Socioeconomic and demographic characteristics were also evaluated. Statistical analysis involved the McNemar χ2 test and conditional logistic regression. RESULTS: The multivariate logistic regression model demonstrated that monthly household income and parental reports of signs of attention deficit were significantly associated with the occurrence of dental caries. CONCLUSION: Children considered by their parents/guardians to have attention deficit have a greater chance of exhibiting dental caries, independently of household income.

Motion sickness prevalence in school children.

UNLABELLED: This study aimed to determine the prevalence of motion sickness in schoolchildren and related the finding to the postural balance and quality of life. A population-based cross-sectional study was carried out with 831 children aged 7 to 12 years. The frequency of motion sickness was evaluated based on the Motion Sickness Susceptibility Questionnaire-Short (MSSQ-short). Postural balance was assessed using the Romberg test under different sensory conditions. The Dizziness Handicap Inventory was used in order to assess the quality of life. The statistical analyses were performed using the chi-square, Kruskal-Wallis, Mann-Whitney, and Spearman correlation tests. The prevalence of motion sickness was 43.4 % in car, 43.2 % on bus, 11.7 % on park swing, and 11.6 % on Ferris wheel. Mean unadjusted scores on the MSSQ-short ranged from 5.0 (SE = 0.5) for 10-year-olds to 6.8 (SE = 0.5) for 9-year-olds. The most prevalent symptoms following the balance tests were dizziness (89.2 %), vertigo (54.9 %), headache (10.6 %), and nausea (8.2 %). Significant correlations were found between the MSSQ-short score and all postural balance tests. Significant correlations were found between the MSSQ and modified DHI (Dizziness Handicap Inventory) at all ages. CONCLUSION: The prevalence of motion sickness in schoolchildren is greater when in a car or on a bus. An association was found between motion sickness and postural balance tests and motion sickness and quality of life.

Developmental defects of enamel in primary teeth: prevalence and associated factors.

BACKGROUND: Studies on the prevalence of enamel defects in the primary dentition as a whole are scarce, as most investigations examine specific population groups. OBJECTIVES: The aim of this study was to evaluate the prevalence of enamel defects in primary teeth and determine whether prematurity, birthweight, and socio-demographic variables are associated with such defects. DESIGN: A cross-sectional study was carried out with 381 children aged 3-5 years. Data were collected through clinical examinations and interviews with parents during the National Immunisation Day. The diagnosis of enamel defects was performed using the Developmental Defects of Enamel (DDE) Index. Through interviews, information was collected on socio-demographic aspects, pregnancy, birthweight, prematurity, and breastfeeding. Statistical analysis was performed using the SPSS program for Windows and involved descriptive analysis, Fisher's exact test, the chi-square test, and Poisson regression. RESULTS: The prevalence of developmental defects of enamel was 29.9%. Demarcated opacity was the most frequent type of defect. Children with a history of very low birthweight had a greater prevalence of enamels defects (PR, 2.7; 95% CI, 1.66-4.61). Prematurity and socio-demographic variables were not associated with enamel defects. CONCLUSION: Children with a history of very low birthweight had a greater frequency of enamel defects in primary teeth.

Degree of dental anxiety in children with and without toothache: prospective assessment.

BACKGROUND: Few prospective studies on the anxiety of children in the dental office have been published. AIMS: To monitor dental anxiety levels in children with and without previous experience with toothache over a period of six consecutive visits. DESIGN: A longitudinal study was carried out involving 167 children treated at a public dental service. Levels of anxiety in the dental setting were assessed in children without toothache (G1) and those with toothache (G2) using the modified Venham picture test (VPT). Data acquisition was carried out over a 6-week period, with each child treated in the dental office once a week. Six assessments of anxiety were performed in the waiting room prior to dental treatment. RESULTS: A significant reduction in anxiety scores occurred between appointments in both groups. In the inter-group comparison, G2 had significantly higher anxiety scores than G1. Although statistically significant reductions in anxiety scores occurred through to the fifth appointment, a tendency toward stagnation in anxiety scores was observed beginning with the fourth appointment. CONCLUSIONS: Dental anxiety scores were reduced over the course of six appointments. Children with toothache had higher levels of dental anxiety than those that had never experienced toothache.

Associations of physical activity and cognitive function with gross motor skills in preschoolers: Cross-sectional study.

Gross motor development in the preschool phase depends on several factors that remain poorly understood. This study aimed to investigate whether level of habitual physical activity (HPA) and global cognitive function (CF) can be used as predictors of gross motor skills in Brazilian preschoolers and to verify their possible mediators. A cross-sectional study was conducted with 166 children, aged 3-5 years. Gross motor skills, HPA, CF and possible mediators (e.g., sex, prematurity) were evaluated. Preschoolers with little HPA, low CF, and girls were more likely to have gross motor performance below expected, but female gender did not mediate HPA or CF. Therefore, HPA and CF, in addition to females, may be independent predictors of delayed gross motor skills in Brazilian preschoolers.

Effects of propolis on lingual mucosa response of hamsters submitted to experimental carcinogenesis.

OBJECTIVE: To assess the tissue reaction of the lingual mucosa in hamsters submitted to daily, alternating, topical applications of 9,10-dimethyl-1,2-benzanthracene (DMBA) and a commercial brand of an ethanol propolis extract (EPE). METHODS: A total of 60 hamsters were divided into three groups with two experimental periods (13 and 20 weeks). The lateral edge of the tongue was submitted to daily, alternating, topical applications of 0.5% DMBA and 30% EPE (EPE group, n=20), 0.5% of DMBA and aqueous propolis extract (APE group, n=20) and 0.5% of DMBA and saline solution (DMBA group, n=20). The occurrence of clinical and histological alterations was analyzed, along with the measurement of the area and volume of the clinical alterations, the determination of structural and cytological alterations of the squamous epithelial tissue with atypias and the measurement of the histological area of squamous cell carcinomas. RESULTS: There were no significant differences among groups regarding any of the variables analyzed in the two evaluation periods. At week 13, a single squamous cell carcinoma occurred in the EPE group. At week 20, the greatest occurrence of squamous cell carcinoma was also in the EPE group. CONCLUSION: The mechanism of EPE (30% alcohol content) affecting the onset of tissue reaction and the promotion of carcinogenesis has not been clarified yet.

Dental caries in schoolchildren: influence of inattention, hyperactivity and executive functions.

Attention-deficit/hyperactivity disorder (ADHD) is characterized by inappropriate levels of hyperactivity, impulsivity, and/or inattention. Individuals with ADHD may present limitations with regard to executive functions and performing activities that involve planning and/or attention/concentration. The aim of the study was to investigate the association between dental caries and signs of ADHD in a representative sample of schoolchildren. A representative sample of 851 schoolchildren aged seven to 12 years was randomly selected from public and private schools. Data acquisition involved a clinical dental examination for cavitated permanent and deciduous teeth using the DMFT/dmft indices. Neuropsychological evaluations, including the assessment of intelligence (Raven's Colored Progressive Matrix Test) and executive functions (Corsi Tapping Blocks tests and Digit Span test) were also performed. Parents/caregivers and teachers answered the SNAP-IV Questionnaire for the investigation of signs of inattention and hyperactivity in the family and school environment. Parents/caregivers also answered questionnaires addressing socioeconomic and socio-demographic characteristics. Descriptive analysis of the variables and Poisson regression with robust variance were performed. Parental reports of signs of inattention (PR: 1.28; p < 0.05) and hyperactivity (PR: 1.15; p < 0.05) were associated with a greater occurrence of caries. A better performance on the backward order of the Corsi Tapping Blocks tests (PR: 0.94; p < 0.05) and higher level of mother's schooling were associated with a lower frequency of caries. A better performance on executive function tasks was a protective factor against dental caries, whereas children considered inattentive and/or hyperactive by their parents had a higher prevalence rate of dental caries.

Association between inflammatory biomarkers in plasma, radiological severity, and duration of exposure in patients with silicosis.

OBJECTIVE: To evaluate the plasma levels of CCL2, CCL3, CCL11, CCL24, tumor necrosis factor alpha, sTNFR1, and sTNFR2 in subjects exposed to silica (SES) with and without silicosis compared with unexposed reference control group, and their associations with the radiological severity and duration of exposure to silica. METHODS: Fifty-seven SES; 36 with silicosis and 22 subjects in control group, were included in the study. RESULTS: CCL3, CCL24, sTNFR1, and sTNFR2 were increased in SES and in SES with silicosis than in controls. There were no differences in the levels of CCL2, CCL11, or tumor necrosis factor alpha. The sTNFR2 level was greater in SES with silicosis than in SES without silicosis. There was a positive correlation between sTNFR1 and sTNFR2 and the radiological severity and time of exposure to silica. sTNFR2 was associated with all categories of radiological severity. CONCLUSION: sTNFR2 is associated with silicosis severity and early exposure to silica.

Is surgical root coverage effective for the treatment of cervical dentin hypersensitivity? A systematic review.

BACKGROUND: Cervical dentin hypersensitivity (CDH) is characterized by tooth pain arising from root exposure. The aim of the present systematic review is to survey the literature on the efficacy of surgical root coverage techniques at reducing CDH in cases of gingival recession. METHODS: An online electronic search was performed in PubMed, Web of Science, and Cochrane Library databases. Randomized clinical trials dating from the inception of the respective databases through November 2011 were selected. Studies addressing clinical parameters of periodontal plastic surgery outcomes and variables related to CDH in patients ≥18 years of age were included. The studies were evaluated by two independent reviewers. For each article, methodologic quality, size effect, the periodontal parameters measured, study design, methods, and results were analyzed. RESULTS: Nine relevant articles were analyzed in the present review. A decrease in CDH was observed after periodontal surgery for root coverage. The risk of bias was considered low in two studies, and the size effect was considered large in one study. CONCLUSIONS: There is not enough scientific evidence to conclude that surgical root coverage procedures predictably reduce CDH. Well-conducted clinical trials are needed to establish scientific evidence that allows periodontists to indicate root coverage as treatment for CDH.

Association between executive/attentional functions and caries in children with cerebral palsy.

The aim of the present study was to evaluate the existence of an association between attention/executive functions and the development of dental caries in individuals with cerebral palsy (CP). Seventy-six children with CP were selected from a physical rehabilitation center and a school serving children with disabilities. The control group was made up of 89 children without neurological impairment. Socioeconomic status, presence of teeth with cavities due to caries, degree of motor impairment and intellectual, executive and attentional functions were assessed. Mean age of participants was 8.9 years (SD=3.56). The CP group had a significantly lower performance (p<0.05, Mann-Whitney test) on the intelligence, attentional function and executive function tests in comparison to the control group. Controlling for the clinical diagnosis (CP or control group), motor impairment and intellectual function, the significant explanatory variables for the presence of teeth with cavities were performance on the Complex Rey figure test (OR=0.941) and the Digit Span subtest of the Wechsler Intelligence Scale for Children in backward order (OR=0.581). After controlling for intellectual function, clinical diagnosis and motor impairment, deficits in executive and attentional functions increased the odds of developing dental caries in children with cerebral palsy.

An ICF-based approach for cerebral palsy from a biopsychosocial perspective.

OBJECTIVES: To integrate instruments to operationalize an ICF-based approach for cerebral palsy (CP); to assess differences in activity and participation among children with hemiplegia, diplegia and quadriplegia CP; to verify the facilitators or barriers to functioning; and to investigate the explanatory factors (cognitive and motor) for the type of school attended by children with CP (regular or special). METHODS: Sixty children with CP were assessed using the Mini-Mental State Examination and an ICF-based instrument and their parents were interviewed. Data were analysed by Chi-Squared, Anova's and Kruskal-Wallis tests and multivariate logistic regression. RESULTS: Significant differences between CP sub-groups were found for chewing, urinary function, cognitive function and activities and participation. Twelve environmental factors were identified as barriers. Multivariate regression identified cognitive function as a significant explanatory variable for the type of school attended, whereas motor function was not significant. CONCLUSIONS: The ICF-based approach allows a comprehensive assessment, relevant for planning interventions.

Does intellectual disability affect the development of dental caries in patients with cerebral palsy?

The aim of this study was to evaluate if the severity of intellectual disability is a factor that affects the development of dental cavities in patients with cerebral palsy. This cross-sectional study was conducted on 165 individuals who were selected from a physical rehabilitation center, a special public school and a regular public school. Of these, 76 individuals had been diagnosed with spastic cerebral palsy and 89 had no neurological impairment. The subjects were matched based on age and gender and selected randomly by lottery. All patients were examined to determine the number of dental cavities, and tested for their intellectual functioning (Raven Test) and motor abilities. The study showed that children with CP who presented with intellectual disabilities had a larger number of dental cavities than children with CP without intellectual disabilities. Considering intellectual functioning and motor impairment in the multivariate logistic regression, only intellectual functioning was found to have a significant effect on the development of dental cavities. These results suggest that intellectual disability can be considered a contributing factor for the development of dental caries in patients with cerebral palsy.

Risk behavior for the human immunodeficiency virus among motel clients.

This study aimed to verify risk behavior for infection with the Human Immunodeficiency Virus in people who attended motels. This is a cross-sectional study conducted in two motels in two municipalities in the state of Minas Gerais, Brazil, with a sample of 308 randomly selected individuals, aged between 18 and 60 years. Bivariate (chi-square and t test for independent samples) and multivariate (logistic regression) statistical tests were performed. A total of 45.8% of the participants reported not having used a condom during the last vaginal sexual intercourse, 48.4% did not use a condom during the last oral sex, while 26.3% reported not having used a condom in the last anal intercourse. Having a steady partner was the strongest predictor of not using condoms. Probable beliefs regarding loyalty involved in a stable relationship may be contributing to the failure to use condoms during intercourse, increasing the risk of HIV infection.

Reconhecimento e avaliação da ansiedade em indivíduos com paralisia cerebral durante consultas odontológicas / Recognition and evaluation of anxiety in individuals with cerebral palsy during dental appointments

Objetivo: o objetivo deste estudo foi verificar a correlação entre a avaliação da ansiedade realizada por meio de medidas fisiológicas e pela observação do comportamento de pacientes com paralisia cerebral realizado pelo dentista durante a primeira consulta odontológica. Métodos: quarenta pacientes com idade variando de 7 a 26 anos, com paralisia cerebral foram submetidos a exames odontológicos. A pressão arterial e a frequência cardíaca foram aferidas no início e no final da primeira consulta odontológica. O dentista avaliou o comportamento antes e após o exame clínico dentário através da observação do comportamento do paciente (inquietação / agitação / tiques nervosos, palidez, transpiração excessiva, resistência e mudança aparente na frequência respiratória). Foi utilizado o teste de correlação de Spearman para determinar a correlação entre as medidas fisiológicas e a classificação comportamental da ansiedade feita pelo cirurgião dentista a um nível de significância de 95%. Resultados: os sinais comportamentais mais frequentes foram inquietação / agitação / tiques nervosos (50,0%) e resistência (27,5%). Foi encontrada uma correlação positiva significativa entre os dois métodos de avaliação de ansiedade utilizados (p <0,05). Os pacientes considerados ansiosos pelo dentista apresentaram medidas fisiológicas mais elevadas do que aqueles considerados calmos (p <0,05). Conclusão: a observação contínua do comportamento de pacientes com paralisia cerebral durante o exame odontológico é uma ferramenta valiosa para o reconhecimento e avaliação da ansiedade por parte da equipe odontológica. Estudos adicionais são necessários para validar um código de expressões faciais e corporais ou reações de ansiedade em pacientes com paralisia cerebral.(AU)

Aim: The present study aimed to verify the correlation between the evaluation of anxiety performed through physiological measures and the observation of the behavior of patients with cerebral palsy performed by the dentist during the first dental visit. Methods: Forty patients with cerebral palsy, varying from seven to 26 years of age, were submitted to dental examinations. The blood pressure and heart rate were measured at the beginning and end of the first dental appointment. The dentist evaluated the behavior before and after the dental exam by observing the patient's behavior (restlessness / agitation / nervous tics, pallor, excessive perspiration, resistance, and apparent change in breathing rate). The Spearman correlation test was used to determine the correlation between the physiological measures and the behavioral classification of anxiety made by the dentist at a significance level of 95%. Results: The most frequent behavioral signs were restlessness / agitation / nervous tics (50.0%), and resistance (27.5%). Through the Kruskal-Wallis test and Spearman's correlation, a significant positive correlation was found between the two anxiety assessment methods used in this study (p<0.05). The patients considered anxious by the dentist presented higher physiological measurements than did those considered calm (p<0.05). Conclusion: It can therefore be concluded that the continuous observation of the behavior of patients with cerebral palsy during the dental examination is a valuable tool for the recognition and evaluation of anxiety on the part of the dental team. Further studies are warranted to validate a code of facial and body expressions or anxiety reactions in patients with cerebral palsy.(AU)

Influence of aerobic training on cardiovascular and metabolic parameters in ederly hypertensive women.

BACKGROUND: Treatment of hypertension includes pharmacological and nonpharmacological interventions. Among the nonpharmacological interventions emphasizes the practice of regular physical exercise. However, the effects of aerobic exercise training on cardiovascular and metabolic parameters in elderly hypertensive women are still controversial. OBJECTIVES: The purpose of this study was to assess the effects of a walking program on metabolic and cardiovascular parameters at rest and during the recovery period following maximal exercise by hypertensive elderly women. METHODS: Twelve elderly women with hypertension started a 2-week walking program. Rest blood cholesterol and anthropometric data, as well as blood pressure and heart rate at rest and after progressive maximal exercise were measured before and after training. RESULTS: There were significant differences between the pre- and posttraining periods in VO(2)max, systolic blood pressure, diastolic blood pressure, and mean blood pressure. There were no changes in serum cholesterol levels after the training. During the recovery period following the progressive test, the fall in heart rate and mean blood pressure after 10 minutes of recovery was significantly higher after training. CONCLUSION: The proposed walking program did not alter serum cholesterol, but it did reduce resting blood pressure, improve aerobic performance and accelerate the fall in heart rate and mean blood pressure during the postprogressive maximal aerobic exercise recovery period in elderly hypertensive women.

Multidisciplinary perspective for cerebral palsy assessment after an international, classification of functioning, disability and health training.

OBJECTIVE: To assess knowledge related to the ICF before and after an ICF training and to identify items to compose a monocentric rehabilitation ICF code set for cerebral palsy (CP). METHODS: (a) DESIGN: A cross-sectional study with a descriptive-explorative design. (b) PARTICIPANTS: Professionals from the fields of physiotherapy, nutrition, dentistry, occupational therapy, psychology, social work, speech therapy and medicine. (c) INSTRUMENT: A questionnaire to assess ICF's knowledge (total score = 17). RESULTS: A high effect size of the ICF training was found (Cohen's d = 4.10). Ninety-one and 43 ICF categories were selected for a comprehensive evaluation and triage, respectively, for CP. CONCLUSION: ICF categories were identified to compose a comprehensive evaluation and for triage through an ICF code sets for CP. Studies are needed to validate the instrument on the knowledge of the ICF and to test the impact of ICF's training for clinical rehabilitation of CP.

School Achievement Test: normative data for a representative sample of elementary school children

The present study established norms for the spelling and arithmetic subtests of the School Achievement Test (Teste do Desempenho Escolar [TDE]) in two Brazilian cities located in the state of Minas Gerais and compared the results with those obtained from the original normative sample. A stratified proportional sample of 1,034 students from Belo Horizonte and Mariana, from the 1st to 6th grades, was selected. The participants were assessed by the spelling and arithmetic subtests of the TDE. Significant differences were found between the results from Minas Gerais and Rio Grande do Sul, with moderate to high effect sizes. Significant differences were found in percentiles and classification parameters. The educational performance of the children from Minas Gerais was generally classified as less than expected (i.e., inferior) when the original norms were used as a classification parameter. Considering the high variability of educational data in different Brazilian regions, using norms for educational assessment based on only one Brazilian region is inappropriate.

Risk behavior for the Human Immunodeficiency Virus among motel clients / Comportamentos de risco frente ao vírus da imunodeficiência humana entre frequentadores de motéis / Las conductas de riesgo al virus de inmunodeficiencia humana entre usuarios de moteles

This study aimed to verify risk behavior for infection with the Human Immunodeficiency Virus in people who attended motels. This is a cross-sectional study conducted in two motels in two municipalities in the state of Minas Gerais, Brazil, with a sample of 308 randomly selected individuals, aged between 18 and 60 years. Bivariate (chi-square and t test for independent samples) and multivariate (logistic regression) statistical tests were performed. A total of 45.8% of the participants reported not having used a condom during the last vaginal sexual intercourse, 48.4% did not use a condom during the last oral sex, while 26.3% reported not having used a condom in the last anal intercourse. Having a steady partner was the strongest predictor of not using condoms. Probable beliefs regarding loyalty involved in a stable relationship may be contributing to the failure to use condoms during intercourse, increasing the risk of HIV infection.

Este estudo teve por objetivo verificar comportamentos de risco referentes à infecção pelo vírus da imunodeficiência humana (HIV) em pessoas que frequentaram motéis. Trata-se de estudo transversal, realizado em dois motéis de dois municípios do interior de Minas Gerais, com amostra de 308 indivíduos, seguindo cálculo amostral, selecionados aleatoriamente, com idade entre 18 e 60 anos. Foram realizados testes estatísticos bivariados (qui-quadrado e teste t para amostras independentes) e multivariados (regressão logística). Dentre os participantes, 45,8% relataram não ter usado preservativo na última relação sexual vaginal, 48,4% não utilizaram preservativo na última relação sexual oral, enquanto 26,3% afirmaram não ter usado na última relação anal. Ter um parceiro fixo foi o maior preditor do não uso do preservativo. Prováveis crenças de fidelidade, envolvidas em um relacionamento estável, podem estar contribuindo para o não uso do preservativo nas relações, aumentando o risco de infecção pelo HIV.

Este estudio tuvo como objetivo determinar las conductas de riesgo al virus de inmunodeficiencia humana en personas que asistieron moteles. Estudio transversal realizado en dos moteles en dos municipios de Minas Gerais con una muestra de 308 personas. Bivariado se realizaron pruebas estadísticas (Jue-cuadrado y t para muestras independientes) y multivariado (regresión logística). La mayoría (42,5%) tenían entre 18 y 25 años y el 45,8% no había utilizado preservativo en sus últimas relaciones sexuales vaginales, 48,4% no usó condón para sexo oral, mientras que 26,3 % reportó no haber utilizado el su última relación anal. Tener una pareja estable fue el mejor predictor para no usarse condones. Llegamos a la conclusión de que la lealtad tiende a estar involucrada en una relación estable puede estar contribuyendo a la no utilización de preservativos en las relaciones, aumentando la vulnerabilidad.
