Explicit and implicit knowledge of environment states induce adaptation in postural control

The aim of this study was to investigate the effects of explicit and implicit knowledge about visual surrounding manipulation on postural responses. Twenty participants divided into two groups, implicit and explicit, remained in upright stance inside a moving room. In the fourth trial participants in the explicit group were informed about the movement of the room while participants in the implicit group performed the trial with the room moving at a larger amplitude and higher velocity. Results showed that postural responses to visual manipulation decreased after participants were told that the room was moving as well as after increasing amplitude and velocity of the room, indicating decreased coupling (down-weighting) of the visual influences. Moreover, this decrease was even greater for the implicit group compared to the explicit group. The results demonstrated that conscious knowledge about environmental state changes the coupling to visual information, suggesting a cognitive component related to sensory re-weighting. Re-weighting processes were also triggered without awareness of subjects and were even more pronounced compared to the first case. Adaptive re-weighting was shown when knowledge about environmental state was gathered explicitly and implicitly, but through different adaptive processes. (C) 2014 Elsevier Ireland Ltd.

Violence against children and adolescents: the importance of knowledge of the spectrum of bruise colors in its diagnosis

Introduction: One of the violence types more observed against children is the physical abuse, which produces many types of traumatic injuries. Contusions are common trauma signs and may indicate aggression when frequently present in locations where accidental injuries are rare. Contusions in skin undergo color changes with the passage of time, and such change in color is called “spectrum of bruise colors of Legrand du Saulle”. Thus, it is possible to estimate the age of the lesion based on the evaluation of color. Injuries caused by child abuse often reach regions of head, face and neck, because they are exposed and easily accessible. Therefore, the dentist is responsible with regard to the diagnosis and the actions to be undertaken against the cases of child abuse. Objective: To present and discuss the significance of the spectrum of bruise colors as a considerable visible trace in suspicion of violence against children and adolescents, during dentists’ clinical routine. Literature review: The study of the “spectrum of bruise colors of Legrand du Saulle” refers to the estimation of the age of the injury, in respect to the color change. The application of this study is of great value for identify if a lesion occurred from a single incident or from multiple incidents, especially in cases where it occurs in the same region of the body, indicative of repetitive trauma. Conclusion: The spectrum of bruise colors is very important for health professionals, such as dentists, for the identification or suspicion of cases of abuse against children and adolescents. As great part of the lesions originated of abuse involve the areas of head and neck, it is unacceptable that these professionals are unaware of the basic signs to help in early diagnosis, which is the case of the colors of the lesions. However, concerning the chronology of the spectrum of bruise colors, it is not possible to establish rigorous times.

Knowledge of professionals from public service on oral health promotion for babies

Health promotion seeks to integrate oral health practices to other public health, by building healthy public policy and the development of strategies directed to all people in the community. This study aimed to analyze the knowledge and actions on the infants’ oral health promotion by dentists, pediatricians and nurses. Were interviewed dentists (n=34), pediatricians (n=31) and nurses (n=26) from Basic Health Units, Family Health Units and Centers for Education and Recreation in Araraquara - SP about knowledge and actions on oral health promotion for infants, by filling out a pre-tested questionnaire. Data were analyzed by association tests. Generally, the professionals are aware of and perform actions on oral health promotion for infants. Most participants were female; mean age of 39.9 years, worked in Basic Health Units, had over 10 years of graduation, demonstrated knowledge on and considered oral health promotion in infants very important. The time since graduation and actions on oral health promotion for infants were associated (p<0.05) with issues concerning the use of dental floss. That most of the professionals who participated in this study know about, take actions on oral health promotion for infants and consider them crucial.

Knowledge of nursing undergraduate students about the use of contact precautions measures

To assess knowledge of nursing undergraduate students about the use of contact precautions. Methodology. There were 106 nursing undergraduate students from three universities within the state of Sao Paulo. The data collection was done between April and May 2012. A questionnaire was elaborated with questions assessing knowledge regarding contact precautions. The data were submitted to statistical procedures in the package MINITAB version 16. The knowledge were rated as adequate, partially adequate and inadequate. Results. There was a predominance of females (86%) and age group between 20 and 29 years (70%). Regarding the definition of contact precaution of diseases in which these measures are used, undergraduate’s knowledge was partially adequate (92% and 44%, respectively). The knowledge was considered adequate for the preventive measures used during assistance (86%). As difficulties mentioned in the use of these measures were discomfort, lack of material, personnel and time. Conclusion. Although undergraduate students know what measures to be used in contact precaution, they do not have adequate knowledge about which diseases they should use them. The three participating universities should reflect on the quality of training for nursing students regarding biosecurity and contact precautions.

Dynamical erosion of asteroid groups in the region of the Phocaea family

In a previous paper, the current state of knowledge of the region containing the Phocaea dynamical family was revised. Here, the dynamical evolution and possible origin of the Phocaea dynamical family and asteroid groups in the region are investigated. First, I study the case of asteroids at high eccentricity (e > 0.31). I find that these objects are unstable because of encounters with Mars on time-scales of up to 270 Myr. The minimum time needed by members of the Phocaea classical family to reach the orbital locations of these objects, 370 Myr, can be used to set a lower limit on the age of the Phocaea family.Next, attention is focused on the chaotic layer previously identified near the nu(6) secular resonance border. Using analytical and numerical tools, I find that the presence of the nu(6) secular resonance forces asteroids with vertical bar g-g(6)vertical bar < 2.55 arcsec yr(-1) to reach eccentricities high enough to allow them to experience deep, close encounters with Mars. Results of the analytical model of Yoshikawa and of my numerical simulations fully explain the low-inclination chaotic region found by Carruba.Finally, I investigate the long-term stability of the minor families and clumps identified in the previous paper, with particular emphasis on a clump only identifiable in the domain of proper frequencies (n, g, g - s) around (6246) Komurotoru. I find that while the clumps identified in the space of proper elements quickly disperse when the Yarkovsky effect is considered, the family around (19536) is still observable for time-scales of more than 50 Myr. The (6246) clump, characterized by its interaction with the nu(5) + nu(16) and 2 nu(6) - nu(16) secular resonances, is robust on time-scales of 50 Myr. I confirm that this group may be the first clump ever detected in the frequency domain that can be associated with a real collisional event.

Efect of an educative action on relatives' knowledge about childhood burns at home

O objetivo deste trabalho foi avaliar o efeito de ação educativa sobre o conhecimento de familiares de crianças a respeito de queimaduras em ambiente doméstico. Participaram 40 familiares de crianças menores de quatro anos, divididos igualmente em grupos intervenção e controle. Foram realizadas entrevista inicial, ação educativa com folder de queimaduras e entrevista após uma semana. As respostas foram comparadas, utilizando-se teste estatístico de Fisher. Na primeira entrevista, registrou-se 60 respostas de situações de risco no grupo controle e 62 no grupo intervenção; na segunda, aumentou para 61 e 80 indicações, respectivamente. Na primeira entrevista, 90% dos participantes do grupo controle e 80% do grupo intervenção verbalizaram acreditar que a queimadura infantil pode ser evitada; na segunda, a indicação diminuiu para 84% e aumentou para 100%, respectivamente. Este estudo mostrou a importância da orientação com folder de queimaduras em ambiente doméstico.

Evaluation of sixth grade primary schoolchildren's knowledge about avulsion and dental reimplantation

Dental trauma, particularly tooth avulsion, is a frequent cause of tooth loss in children, adolescents, and young adults. The avulsed tooth should be immediately reimplanted in its alveolus. This procedure can be performed by anyone at the accident site and not only by dental surgeons. Therefore, the purpose of this study is to evaluate the knowledge of sixth graders of the city of Aracatuba, SP, about dental avulsion and tooth reimplantation through a structured and standardized survey. Our sample consisted of 778 students. The data collected was processed using the program epiinfo 2000. Most students were around 12 years of age and 94.5% related to practice some kind of sports. Results demonstrated that the possibility of tooth reimplantation after dental avulsion is not acknowledged among these students and dental traumatism was associated to caries, toothache, and use of orthodontic appliances. Only 18.9% of the students associated dental traumatism to an impact trauma; 3.6% would store the tooth in milk, and 3.1% believed the tooth could be reimplanted by anyone present at the accident site. In summary, the results show an overall the lack of knowledge about dental traumatism and highlight the need of special programs designed to educate school-aged students about emergency procedures to handle cases of dental traumatisms.

Crown and crown-root fractures: an evaluation of the treatment plans for management proposed by 154 specialists in restorative dentistry

Traumatic tooth injuries involve function and aesthetics and cause damage that range from minimal enamel loss to complex fractures involving the pulp tissue and even loss of the tooth crown. Technical knowledge and clinical experience are essential to establish an accurate diagnosis and provide a rational treatment. The purpose of this study was to evaluate the knowledge of Restorative Dentistry specialists about the management of crown and crown-root fractures based on treatment plans proposed by these professionals for these cases. A descriptive questionnaire was mailed to 245 Restorative Dentistry specialists with questions referring to their professional profile and the treatment plans they would propose for the management of crown and crow-root fractures resulting from dental trauma. One hundred and fifty-four questionnaires were returned properly filled. The data were subjected to descriptive statistics and the chi-square test was used to determine the frequency and the level of the significance among the variables. The analysis of data showed that in spite of having a specialist title, all interviewees had great difficulty in planning the treatments. As much as 42.8% of the participants were unable to treat all types of dental trauma. Complicated and uncomplicated crown-root fractures posed the greatest difficulties for the dentists to establish adequate treatment plans because these fractures require multidisciplinary knowledge and approach for a correct case planning and prognosis.
