Relation between motor perfomance and physical fi tness level of schoolchildren
Introduction: Children with poor motor performance, engage in less vigorous and organized activities, contributing to low scores in physical fi tness assessments. However, there is no consensus in the literature about the association between variables. Objective: Evaluate the relationship between motor performance and physical fi tness of students between 7 and 10 years old. Methods: Ninety-eight (98) students enrolled in a public school in Florianópolis, Santa Catarina State, Brazil, participated in this study. For motor evaluation, the Movement Assessment Battery for Children - Second Edition (MABC-2) was used; the assessment of physical fi tness was performed using the guidelines of the Brazil Sport Project (PROESP-BR). Data were tabulated in the Statistical Package for Social Sciences (SPSS) for the descriptive statistical analysis (mean, standard deviation, frequency) and inferential analysis (Student’s t-test, Mann-Whitney U test, and multiple linear regression test). The signifi cance level was set at p < 0.05. Results: The values of the prevalence of motor diffi culty and motor diffi culty risk were 5.9% and 13.9%, respectively, and the value for without diffi culty of movement was 80.2%. Differences were found for males in the agility tests and explosive strength of the lower limbs (p < 0.05), in which the boys with motor diffi culty showed lower values. We noticed that abdominal strength, endurance, and agility significantly contributed to explain the variability in motor performance, which together showed a coeffi cient of determination (R²) of 0.13. Conclusion: Abdominal strength/endurance and agility contributed signifi cantly in explaining the variability in motor performance. Thus, it is fundamental to encourage involvement in activities that contribute to the increase in motor repertoire refl ecting physical fi tness
Crianças respiradoras bucais apresentam padrão cefalométrico semelhante àquele observado em pacientes adultos com síndrome da apnéia obstrutiva do sono
OBJECTIVE: To determine whether mouth breathing children present the same cephalometric patterns as patients with obstructive sleep apnea syndrome (OSAS). METHOD: Cephalometric variables were traced and measured on vertical lateral cephalometric radiographs. The cephalometric measurements of 52 mouth and 90 nose breathing children were compared with apneic patients. The children had not undergone adenoidectomy or tonsillectomy and had not had or were not receiving orthodontic or orthopedic treatment. RESULTS: Mouth breathing children showed same cephalometric pattern observed in patients with OSAS: a tendency to have a retruded mandible (p=0.05), along with greater inclination of the mandibular and occlusal planes (p<0.01) and a tendency to have greater inclination of the upper incisors (p=0.08). The nasopharyngeal and posterior airway spaces were greatly reduced in mouth breathing children, as observed in patients with apnea (p<0.01). CONCLUSION: Mouth breathing children present abnormal cephalometric parameters and their craniofacial morphology resembles that of patients with OSAS.OBJETIVO: Determinar se crianças respiradoras bucais apresentam o mesmo padrão cefalométrico que os pacientes que tem síndrome da apnéia obstrutiva do sono (SAOS). MÉTODO: Foram traçadas radiografias laterais verticais da cabeça para a mensuração das variáveis cefalométricas. As medidas cefalométricas de 52 crianças respiradoras bucais e de 90 crianças respiradoras nasais foram comparadas à de pacientes com apnéia. Foram excluídas as crianças que haviam sido submetidas à cirurgia de remoção de amídalas ou adenóides, ou que haviam recebido tratamento ortodôntico prévio ou em andamento. RESULTADOS: As crianças respiradoras bucais apresentaram o mesmo padrão cefalométrico observado em pacientes com SAOS: tendência a ter retrusão de mandíbula (p=0,05), assim como uma maior inclinação dos planos mandibular e oclusal (p<0,01) e tendência a ter maior inclinação dos incisivos superiores (p=0,08). O espaço da nasofaringe e o espaço aéreo posterior se apresentaram muito diminuídos nas crianças respiradoras bucais, como é observado em pacientes com SAOS (p<0,01). CONCLUSÃO: Crianças respiradoras bucais apresentam padrão cefalométrico alterado e sua morfologia craniofacial é semelhante àquela observada em pacientes com SAOS.Federal University of São Paulo Hospital São Paulo Department of NeurologyUNIFESP, Hospital São Paulo Department of NeurologySciEL
Clinical co-morbidities in obstructive sleep apnea syndrome treated with mandibular repositioning appliance
Introduction: Intraoral mandibular repositioner appliances (IOMRAs) are designed to enlarge pharyngeal airway space advancing the mandible and increasing genioglossus tone during sleep. Obstructive sleep apnea syndrome (OSAS) treatment with IOMRAs is beneficial, but there is a lack of studies in the literature defining the target population more inclined to respond to this treatment.Methods: We contacted by telephone 188 previously treated patients with IOMRA, detecting 20 not improved patients (Study Group). Twenty improved patients of the remaining 168 were randomly paired according to gender, age, apnea, and hypopnea index as Control Group. Both groups answered questionnaires for diagnosis of sleep disorders, depression, anxiety, and the Epworth sleepiness scale. We did a descriptive and inferential statistical analysis. the inferential analysis was divided into two steps: univariate analysis using Fischer exact test and a multiple inferential analysis using a stepwise regression model.Results: Although the final model included only insomnia, we concluded that the presence of gastric, neurological and rheumatic diseases also tended to be associated with the self-perception of non-improvement. the association between the accumulation of gastric, neurological, and rheumatic diseases and insomnia and improvement demonstrated that an increase in one of these diseases correspond to a two-fold increase in the chance of non-improvement.Conclusions: Insomnia was the most important factor compromising the, success of OSAS treatment with IOMRAs, and the isolated presence of gastric, neurological and rheumatic diseases, but especially their combination, reduces the perception rate of welt-succeeded treatment with IOMRAs.

A apneia obstrutiva do sono impede a esperada diferença de crescimento cranofacial de meninos e meninas
OBJECTIVES: It was to compare cephalometric measures of mouth-breather boys and girls and with the cephalometric pattern observed in obstructive sleep apnea syndrome (OSAS) patients. METHODS: Craniofacial measurements of lateral cephalometric radiographs obtained from 144 children aged 7-14 years were compared between boys and girls, and both were compared to cephalometric pattern of OSAS patients. RESULTS: Mouth-breather boys and girls had no gender differences regarding to craniofacial morphology while nose-breather boys and girls showed those expected differences. Nose-breather boys presented a more retruded mandible and proinclined upper incisor when compared to nose-breather girls, but mouth-breather boys and girls had no differences. The measure NS.GoGn was the only variable with an interaction with gender and breathing. CONCLUSIONS: There were no cephalometric difference in mouth breather-boys and girls related to normal growth, suggesting that oral breathing make the same craniofacial morphology and both have craniofacial morphology close to that of OSAS patients.OBJETIVOS: Foi comparar medidas cefalométricas entre meninos e meninas respiradores bucais com o padrão cefalométrico de pacientes com síndrome da apneia obstrutiva do sono (SAOS). MÉTODOS: Medidas craniofaciais de radiografias cefalométricas laterais de 144 crianças com idade entre 7 e 14 anos foram comparadas entre meninos e meninas, e estas comparadas com o padrão cefalométrico de pacientes com SAOS. RESULTADOS: Meninos e meninas respiradores bucais não apresentaram diferenças em relação à morfologia craniofacial, enquanto meninos e meninas respiradores nasais mostraram as diferenças fisiologicamente esperadas. Meninos respiradores nasais apresentaram mandíbula mais retraída e incisivos superiores inclinados para frente quando comparados com meninas respiradoras nasais, mas os respiradores bucais não apresentaram diferenças. A medida NS.GoGn foi a única variável com interação entre gênero e tipo de respiração. CONCLUSÕES: Não houve diferença cefalométrica entre os respiradores bucais em relação ao crescimento craniofacial, sugerindo que a respiração bucal determina a mesma morfologia, e ambos os gêneros têm morfologia craniofacial semelhante àquela dos pacientes com SAOS.Universidade Federal de Sào Paulo São Paulo Hospital Department of NeurologySciEL
INCIDÊNCIA DE CONSUMO DE BEBIDA ALCOÓLICA ENTRE AS VÍTIMAS DE SUICÍDIO NO DISTRITO FEDERAL
Suicide is motivated by multiple causes, and the abusive consumption of alcoholic beverages can be an important sign that individuals do not have physical and emotional control of themselves. To estimate the incidence of alcohol consumption, immediately before suicide, among people who died in 2018 in the Brazilian Federal District. This is a population-based study, of a descriptive and exploratory nature, of all deaths which occurred in the Brazilian Federal District from January 1 to December 31, 2018. Data were collected from the Mortality Information System and Police reports. The incidence and respective 95% confidence intervals were calculated. This study was approved by the Research Ethics Committee. The incidence of alcohol consumption just before the suicide was 18.6% (CI 95%: 18.56% to 18.62%). Males, blacks, trade workers, those without a partner, young people, and individuals with less than 8 years of study had the highest indicators. There was a greater percentage of alcohol consumption in the fall/winter, at the end of the month, in rural areas, in people who had never attempted suicide before and when the modus operandi was choking or hanging. The consumption of drugs, such as methamphetamine, ecstasy, amphetamine, and cannabis, was observed together with alcoholic beverages. The results of this research signaled an important public health problem, which is the use of alcohol to potentially encourage suicide. Effective public policies to tackle the abusive consumption of alcoholic beverages and suicide are necessary.O suicídio é motivado por múltiplas causas e o consumo abusivo de bebidas alcoólicas pode ser um sinal importante de que os indivíduos não têm controle físico e emocional de si mesmos.

Enhancing Network Slicing Architectures with Machine Learning, Security, Sustainability and Experimental Networks Integration
Network Slicing (NS) is an essential technique extensively used in 5G
networks computing strategies, mobile edge computing, mobile cloud computing,
and verticals like the Internet of Vehicles and industrial IoT, among others.
NS is foreseen as one of the leading enablers for 6G futuristic and highly
demanding applications since it allows the optimization and customization of
scarce and disputed resources among dynamic, demanding clients with highly
distinct application requirements. Various standardization organizations, like
3GPP's proposal for new generation networks and state-of-the-art 5G/6G research
projects, are proposing new NS architectures. However, new NS architectures
have to deal with an extensive range of requirements that inherently result in
having NS architecture proposals typically fulfilling the needs of specific
sets of domains with commonalities. The Slicing Future Internet Infrastructures
(SFI2) architecture proposal explores the gap resulting from the diversity of
NS architectures target domains by proposing a new NS reference architecture
with a defined focus on integrating experimental networks and enhancing the NS
architecture with Machine Learning (ML) native optimizations, energy-efficient
slicing, and slicing-tailored security functionalities. The SFI2 architectural
main contribution includes the utilization of the slice-as-a-service paradigm
for end-to-end orchestration of resources across multi-domains and
multi-technology experimental networks. In addition, the SFI2 reference
architecture instantiations will enhance the multi-domain and multi-technology
integrated experimental network deployment with native ML optimization,
energy-efficient aware slicing, and slicing-tailored security functionalities
for the practical domain.Comment: 10 pages, 11 figure
