Políticas públicas e direitos de crianças e adolescentes: o papel da mídia na expansão da cidadania

This paper presents results of an evaluation of the quality of the coverage of issues associated to the preservation of rights of children and adolescents in the eight main newspapers of major cities of Bauru (Sao Paulo State) administrative region, from August 2008 to March 2009. In a total of 389 assessed stories, 66% portrayed acts of legal infraction and violence with children and adolescents as victims or perpetrators, with a fragmented and superficial perspective; 34% are greater approaches about public policies aimed at the preservation of social rights. The results show the existence of a smaller number, yet significant, of stories which presented extended and more contextualized approaches. From a general view, we can point out that the contribution given by the media as a form of vigilance over the execution of public policies has been limited, which justifies the concern of demanding, from the mass media, measures to fulfill the role attributed to them by contemporaneous democracies to the strengthening of citizenship.

Avaliação da participação e confiabilidade da população em relação à campanha de vacinação anual contra a raiva de cães e gatos no município de Botucatu, São Paulo, Brasil

The annual vaccination campaign against rabies is the most effective prevention procedure for this disease in dogs and cats and hence for human protection also. However, in 2010 and 2011, this activity was interrupted in Brazil due to the occurrence of adverse events associated with vaccination. Even though cases of canine rabies have been decreasing in the last two decades, vigilance must be strengthened in order to maintain pet owners trust in the vaccines provided in public services. This study aimed to determine pet owners participation in the annual vaccination campaign carried out in Botucatu. During March and April 2012, the period before the 42nd campaign, 312 pet owners, dogs and cats, were interviewed. The homes were randomly drawn in blocks from different sectors of the city; all houses on the same block over the 120 km² of urban area participated in the sampling process. Statistical analysis was performed descriptively. The results showed that the owners main motivation to vaccinate their pets during the campaigns is rabies prevention (36%), followed by the proximity of the vaccination station to the house (20.7%), zero cost (10.9%), and the combination of all three factors (16.1%). When asked if they would take their animals back to be vaccinated in another campaign, 60.1% answered yes, 13.5% would go to a private clinic, 2.2% would not take because they do not trust the vaccine and 1.6% had not decided yet. We conclude that the respondents have realized how dangerous Rabies is, because even after the break period, they still utilized the vaccination campaign demonstrating confidence in its effectiveness, while knowing the campaign goals facilitates understanding and participation.

Predator and Heterospecific Stimuli Alter Behavior in Cattle

Wild and domestic ungulates modify their behavior in the presence of olfactory and visual cues of predators but investigations have not exposed a domestic species to a series of cues representing various predators and other ungulate herbivores.We used wolf (Canis lupus), mountain lion (Puma concolor), and mule deer (Odocoileus hemionus) stimuli (olfactory and visual), and a control (no stimuli) to experimentally test for differences in behavior of cattle (Bos taurus) raised in Arizona. We measured (1) vigilance, (2) foraging rates, (3) giving up density (GUD) of high quality foods and (4) time spent in high quality forage locations in response to location of stimuli treatments. In general, we found a consistent pattern in that wolf and deer treatments caused disparate results in all 4 response variables. Wolf stimuli significantly increased cattle vigilance and decreased cattle foraging rates; conversely, deer stimuli significantly increased cattle foraging rate and increased cattle use of high quality forage areas containing stimuli. Mountain lion stimuli did not significantly impact any of the 4 response variables. Our findings suggest that domestic herbivores react to predatory stimuli, can differentiate between stimuli representing two predatory species, and suggest that cattle may reduce antipredatory behaviour when near heterospecifics.

Evaluation of the capability of decentralized management of epidemiological surveillance in the state of Bahia

Evaluative research into the capability of decentralized management of epidemiological vigilance (EV) was conducted in the operational, organizational and sustainable dimensions in the state of Bahia, Brazil. The quantitative approach was used in the construction of a baseline, with primary data obtained through an online questionnaire answered by thirty-eight municipal EV managers. In the qualitative approach to analyze the context and assess the management capability of municipalities in two case studies, techniques adapted to the analysis of discursive practices were used. This was done through semi-structured interviews with managers of regional and municipal government, health workers and representatives of the municipal health council. The case studies showed that the municipality with enhanced management capability is that in which the manager has the greatest potential of using the resources of his position, in addition to his ability to control, negotiate and coordinate with other actors. Due to decentralization of EV, considering the shared nature of management between the three spheres of government, there is a marked variation in the management capability of municipalities, determined by social, economic, political inequalities and management mechanisms adopted.

Acidentes e violência na infância: evidências do inquérito sobre atendimentos de emergência por causas externas - Brasil, 2009

Compreender as características e a magnitude das causas externas (acidentes e violência) em crianças de 0 a 9 anos de idade torna-se cada vez mais importante em Saúde Pública. O objetivo do presente artigo foi analisar os atendimentos de emergência por causas externas em crianças. Utilizaram-se dados do Sistema de Vigilância de Violências e Acidentes em Serviços Sentinelas de Urgência e Emergência (Inquérito VIVA), realizado em 74 serviços de urgência do Distrito Federal e 23 capitais no ano 2009. Analisaram-se dados de 7.123 crianças: 6.897 (96,7%) vítimas de acidentes e 226 (3,3%) de violência. Em comparação às vítimas de violência, os atendimentos por acidentes foram mais frequentes entre crianças de 2 a 5 anos, de pele branca e ocorridos no domicílio (p < 0,05). Dentre os acidentes, as quedas e queimaduras predominaram no grupo de 0 a 1 ano, enquanto os acidentes de transporte foram mais frequentes no grupo de 6 a 9 anos (p < 0,001). Quanto às violências, atendimentos por negligência e agressão física predominaram, respectivamente, nos grupos extremos de faixa etária, sendo um familiar identificado como agressor (p < 0,001). Informações sobre ocorrência de causas externas em crianças podem apoiar políticas de promoção da saúde, além de orientar profissionais de saúde, educadores e famílias na prevenção destas causas.

Bone mineral density in postmenopausal women with and without breast cancer

OBJECTIVE: The values of bone mineral density (BMD) were compared in postmenopausal women with and without breast cancer. METHODS: A cross-sectional study was conducted, including 51 breast cancer survivors (BCS) and 71 women without breast cancer, who were non-users of hormone therapy, tamoxifen, or aromatase inhibitors. BMD T-scores and measurements in grams per centimeter squared (g/cm²) were obtained at the femoral neck, trochanter, Ward's triangle, and lumbar spine. Osteopenia and osteoporosis were grouped and categorized as abnormal BMD. Unconditional logistic regression analysis was used to estimate the odds ratios (OR) of abnormal BMD values as measures of association, with 95% confidence intervals (CIs), adjusting for age, years since menopause, parity, and body mass index (BMI). RESULTS: The mean age of the women with and without breast cancer was 54.7 ± 5.8 years and 58.2 ± 4.8 years (p < 0.01), respectively. After adjusting for age, parity and BMI, abnormal BMD at the femoral neck (adjusted OR: 4.8; 95% CI: 1.5-15.4), trochanter (adjusted OR: 4.6; 95% CI: 1.4-15.5), and Ward's triangle (adjusted OR: 4.5; 95% CI: 1.5-12.9) were significantly more frequent in postmenopausal BCS than in women without breast cancer. Postmenopausal BCS had a significantly lower mean BMD at the trochanter (0.719 vs. 0.809 g/cm², p < 0.01) and at the Ward's triangle (0.751 vs. 0.805 g/cm², p = 0.03). CONCLUSION: The prevalence of abnormal BMD was higher in postmenopausal BCS than in postmenopausal women without breast cancer. Bone health requires special vigilance and the adoption of interventions should be instituted early to minimize bone loss in BCS.

Genetic characterization and molecular identification of the bloodmeal sources of the potential bluetongue vector Culicoides obsoletus in the Canary Islands, Spain

[EN] Background: Culicoides (Diptera: Ceratopogonidae) biting midges are vectors for a diversity of pathogens including bluetongue virus (BTV) that generate important economic losses. BTV has expanded its range in recent decades, probably due to the expansion of its main vector and the presence of other autochthonous competent vectors. Although the Canary Islands are still free of bluetongue disease (BTD), Spain and Europe have had to face up to a spread of bluetongue with disastrous consequences. Therefore, it is essential to identify the distribution of biting midges and understand their feeding patterns in areas susceptible to BTD. To that end, we captured biting midges on two farms in the Canary Islands (i) to identify the midge species in question and characterize their COI barcoding region and (ii) to ascertain the source of their bloodmeals using molecular tools.Methods: Biting midges were captured using CDC traps baited with a 4-W blacklight (UV) bulb on Gran Canaria and on Tenerife. Biting midges were quantified and identified according to their wing patterns. A 688 bp segment of the mitochondrial COI gene of 20 biting midges (11 from Gran Canaria and 9 from Tenerife) were PCR amplified using the primers LCO1490 and HCO2198. Moreover, after selected all available females showing any rest of blood in their abdomen, a nested-PCR approach was used to amplify a fragment of the COI gene from vertebrate DNA contained in bloodmeals. The origin of bloodmeals was identified by comparison with the nucleotide-nucleotide basic alignment search tool (BLAST). Results: The morphological identification of 491 female biting midges revealed the presence of a single morphospecies belonging to the Obsoletus group. When sequencing the barcoding region of the 20 females used to check genetic variability, we identified two haplotypes differing in a single base. Comparison analysis using the nucleotide-nucleotide basic alignment search tool (BLAST) showed that both haplotypes belong to Culicoides obsoletus, a potential BTV vector. As well, using molecular tools we identified the feeding sources of 136 biting midges and were able to confirm that C. obsoletus females feed on goats and sheep on both islands.Conclusions: These results confirm that the feeding pattern of C. obsoletus is a potentially important factor in BTV transmission to susceptible hosts in case of introduction into the archipelago. Consequently, in the Canary Islands it is essential to maintain vigilance of Culicoides-transmitted viruses such as BTV and the novel Schmallenberg virus.

Seizure prediction and control in epilepsy

The first part of my thesis presents an overview of the different approaches used in the past two decades in the attempt to forecast epileptic seizure on the basis of intracranial and scalp EEG. Past research could reveal some value of linear and nonlinear algorithms to detect EEG features changing over different phases of the epileptic cycle. However, their exact value for seizure prediction, in terms of sensitivity and specificity, is still discussed and has to be evaluated. In particular, the monitored EEG features may fluctuate with the vigilance state and lead to false alarms. Recently, such a dependency on vigilance states has been reported for some seizure prediction methods, suggesting a reduced reliability. An additional factor limiting application and validation of most seizure-prediction techniques is their computational load. For the first time, the reliability of permutation entropy [PE] was verified in seizure prediction on scalp EEG data, contemporarily controlling for its dependency on different vigilance states. PE was recently introduced as an extremely fast and robust complexity measure for chaotic time series and thus suitable for online application even in portable systems. The capability of PE to distinguish between preictal and interictal state has been demonstrated using Receiver Operating Characteristics (ROC) analysis. Correlation analysis was used to assess dependency of PE on vigilance states. Scalp EEG-Data from two right temporal epileptic lobe (RTLE) patients and from one patient with right frontal lobe epilepsy were analysed. The last patient was included only in the correlation analysis, since no datasets including seizures have been available for him. The ROC analysis showed a good separability of interictal and preictal phases for both RTLE patients, suggesting that PE could be sensitive to EEG modifications, not visible on visual inspection, that might occur well in advance respect to the EEG and clinical onset of seizures. However, the simultaneous assessment of the changes in vigilance showed that: a) all seizures occurred in association with the transition of vigilance states; b) PE was sensitive in detecting different vigilance states, independently of seizure occurrences. Due to the limitations of the datasets, these results cannot rule out the capability of PE to detect preictal states. However, the good separability between pre- and interictal phases might depend exclusively on the coincidence of epileptic seizure onset with a transition from a state of low vigilance to a state of increased vigilance. The finding of a dependency of PE on vigilance state is an original finding, not reported in literature, and suggesting the possibility to classify vigilance states by means of PE in an authomatic and objectic way. The second part of my thesis provides the description of a novel behavioral task based on motor imagery skills, firstly introduced (Bruzzo et al. 2007), in order to study mental simulation of biological and non-biological movement in paranoid schizophrenics (PS). Immediately after the presentation of a real movement, participants had to imagine or re-enact the very same movement. By key release and key press respectively, participants had to indicate when they started and ended the mental simulation or the re-enactment, making it feasible to measure the duration of the simulated or re-enacted movements. The proportional error between duration of the re-enacted/simulated movement and the template movement were compared between different conditions, as well as between PS and healthy subjects. Results revealed a double dissociation between the mechanisms of mental simulation involved in biological and non-biologial movement simulation. While for PS were found large errors for simulation of biological movements, while being more acurate than healthy subjects during simulation of non-biological movements. Healthy subjects showed the opposite relationship, making errors during simulation of non-biological movements, but being most accurate during simulation of non-biological movements. However, the good timing precision during re-enactment of the movements in all conditions and in both groups of participants suggests that perception, memory and attention, as well as motor control processes were not affected. Based upon a long history of literature reporting the existence of psychotic episodes in epileptic patients, a longitudinal study, using a slightly modified behavioral paradigm, was carried out with two RTLE patients, one patient with idiopathic generalized epilepsy and one patient with extratemporal lobe epilepsy. Results provide strong evidence for a possibility to predict upcoming seizures in RTLE patients behaviorally. In the last part of the thesis it has been validated a behavioural strategy based on neurobiofeedback training, to voluntarily control seizures and to reduce there frequency. Three epileptic patients were included in this study. The biofeedback was based on monitoring of slow cortical potentials (SCPs) extracted online from scalp EEG. Patients were trained to produce positive shifts of SCPs. After a training phase patients were monitored for 6 months in order to validate the ability of the learned strategy to reduce seizure frequency. Two of the three refractory epileptic patients recruited for this study showed improvements in self-management and reduction of ictal episodes, even six months after the last training session.

Entwicklung und Überprüfung objektiver Testverfahren zur Messung von Angstbewältigungsdispositionen

Für die Entwicklung objektiver Testverfahren zur Messung von Angstbewältigungsdispositionen, d.h. von Tests, deren Meßprinzip für die Probanden nicht durchschaubar ist, wurde das Dot-Probe-Paradigma verwendet. Mit diesem Paradigma läßt sich das Aufmerksamkeitsverhalten gegenüber bedrohlichem Material messen. Es wurde angenommen, daß dieses Paradigma besonders gut für eine objektive Messung der Angstbewältigungsdispositionen Vigilanz und kognitive Vermeidung geeignet ist, da Vigilanz durch verstärkte Aufnahme und Verarbeitung bedrohungsbezogener Information gekennzeichnet ist, während sich kognitive Vermeidung in der Abwendung der Aufmerksamkeit von diesen Reizen zeigt. In drei Studien wurde für verschiedene Versionen des Dot-Probe-Paradigmas überprüft, ob die für den Einsatz als Testinstrument in der Persönlichkeitsdiagnostik notwendigen Gütekriterien erfüllt sind. Dabei wurde festgestellt, daß das Dot-Probe-Paradigma sowohl bei Verwendung von Wörtern als auch von Bildern als Stimuli für klinisch unauffällige Testpersonen keine reliable Messung ermöglicht. Die erhobenen Werte waren weder über eine Woche hinweg stabil, noch waren sie intern konsistent. Infolge der ungenügenden Reliabilität fanden sich in den Studien nur unsystematische Befunde zum Zusammenhang zwischen dem Aufmerksamkeitsverhalten im Dot-Probe-Paradigma und verschiedenen Fragebogenmaßen. Darüber hinaus vermag die mangelnde Reliabilität auch die in der Literatur berichteten inkonsistenten Befunde bei der Untersuchung nicht-klinischer Stichproben mit diesem Paradigma zu erklären. Mögliche Gründe für die mangelnde Reliabilität der Messung werden diskutiert.

Broschüren zur Früherkennung von Hautkrebs

In der vorliegenden Studie wurde überprüft, ob Broschüren, die negative Konsequenzen unzureichender Hautselbstuntersuchung (HSU) betonen (Verlustrahmung), besser geeignet sind, die Früherkennung von Hautkrebs zu fördern als Broschüren, die positive Konsequenzen bei richtig durchgeführter HSU schildern (Gewinnrahmung). Geschlecht und die Bewältigungsdispositionen Vigilanz und kognitive Vermeidung wurden als mögliche Moderatorvariablen untersucht. Nach Erfassung von Baseline- und Hintergrundvariablen lasen 180 Teilnehmer jeweils eine der Broschüren, die ihnen per Zufall zugeteilt wurde. Diese variierten in Rahmung (Gewinn/Verlust) und Bedrohungsgrad (gering/hoch), so dass vier unterschiedliche Versionen vorlagen. Rahmung und Bedrohungsgrad wirkten sich in Abhängigkeit von Vigilanz, d.h. der Disposition, bedrohungsbezogene Informationen systematisch zu verarbeiten, auf die Intention aus. Deutlicher war die Wirkung der Rahmung auf die berichtete Häufigkeit von HSU, die zwei Monate nach dem Lesen erneut erfragt worden war. In der Verlustbedingung stieg die berichtete Häufigkeit von HSU bei Personen mit hoher Vigilanz, bei Personen mit niedriger Vigilanz dagegen sank sie. In der Gewinnbedingung profitierten Personen mit niedriger Vigilanz, während Personen mit hoher Vigilanz weniger HSU berichteten als zuvor. Diese Effekte korrespondierten zwar mit Änderungen der eigenen Risikowahrnehmung, der Erinnerungsleistung und der Beschäftigung mit dem Studienthema, jedoch ließ sich für keine dieser Variablen eine vermittelnde Wirkung nachweisen. Einstellung und Anforderung von Informationsmaterialien blieben unbeeinflusst.

Facetten emotionaler Expressivität auf Fragebogenebene

Der Dimensionierung emotionaler Expressivität auf Fragebogenebene wurde in zwei Untersuchungen nachgegangen. Gross und John (1998) untersuchten die Items bestehender Fragebogen auf ihre dimensionale Struktur hin und ermittelten die fünf Facetten positive und negative Expressivität, Impulsstärke, Darstellungsfähigkeit (expressive confidence) und Verstellungstendenz (masking), wobei die drei erstgenannten in einem hierarchischen Modell einen engeren Zusammenhang mit einander aufwiesen (Kern-Expressivität) als die beiden anderen. Untersuchung 1 ging den Fragen nach, ob sich die gleichen Dimensionen auch mit deutschen Adaptationen der Fragebogen finden lassen, und ob sich die dimensionale Struktur ändert, wenn weitere Fragebogen aus dem Bereich der Expressivität hinzugenommen werden. Die Dimensionen von Gross und John (1998) konnten nur zum Teil repliziert werden. Dies und die Ergebnisse des erweiterten Itempools führten zur Formulierung eines modifizierten (erweiterten) Modells der Facetten emotionaler Expressivität. In Untersuchung 2 wurden Items für einen Fragebogen zu Facetten emotionaler Expressivität (FFEE) formuliert, welche die im modifizierten Modell spezifizierten Dimensionen erheben sollten. Die drei postulierten übergeordneten Bereiche Kern-Expressivität, soziale Expressivität und kognitive Expressivität konnten auch empirisch gefunden werden. Darüber hinaus differenzierten sich die negativen Items der Kern-Expressivität stärker als die positiven. Die Zusammenhänge mit externen Expressivitäts-Fragebogen, den globalen Persönlichkeitsmerkmalen Extraversion und Neurotizismus und den Angstbewältigungsdimensionen Vigilanz und kognitive Vermeidung bestätigten die Validität des FFEE. Theoretische Implikationen und Ansatzpunkte für weitere Forschungen wurden diskutiert.

Einfluss neurologischer Krankheitsbilder auf die Vigilanz gemessen mit dem Pupillographischen Schläfrigkeitstest

Zahlreiche neurologische Erkrankungen wie Morbus Parkinson oder Epilepsien sind mit nicht erholsamem Schlaf und erhöhter Tagesschläfrigkeit assoziiert. Andere Erkrankungen wie Multiple Sklerose induzieren zwar Fatigue / Müdigkeit, aber keine objektivierbar erhöhte Einschlafneigung. Aufgrund der komplexen Interaktionen von Grunderkrankung, Krankheitsfolgen und Medikationseffekten differieren subjektive Einschätzung und objektive Maße von Schläfrigkeit oft erheblich. Der pupillographische Schläfrigkeitstest (PST) ist ein effizientes und objektives Verfahren zur Bestimmung der Vigilanz bzw. Tagesschläfrigkeit, für neurologische Patienten unter naturalistischen Bedingungen liegen aber nur wenige Daten vor.

Excitability and recruitment patterns of spinal motoneurons in human sleep as assessed by F-wave recordings

This study examines the excitability and recruitment of spinal motoneurons in human sleep. The main objective was to assess whether supraspinal inhibition affects the different subpopulations of the compound spinal motoneuron pool in the same way or rather in a selective fashion in the various sleep stages. To this end, we studied F-conduction velocities (FCV) and F-tacheodispersion alongside F-amplitudes and F-persistence in 22 healthy subjects in sleep stages N2, N3 (slow-wave sleep), REM and in wakefulness. Stimuli were delivered on the ulnar nerve, and F-waves were recorded from the first dorsal interosseus muscle. Repeated sets of stimuli were stored to obtain at least 15 F-waves for each state of vigilance. F-tacheodispersion was calculated based on FCVs using the modified Kimura formula. Confirming the only previous study, excitability of spinal motoneurons was generally decreased in all sleep stages compared with wakefulness as indicated by significantly reduced F-persistence and F-amplitudes. More importantly, F-tacheodispersion showed a narrowed range of FCV in all sleep stages, most prominently in REM. In non-REM, this narrowed range was associated with a shift towards significantly decreased maximal FCV and mean FCV as well as with a trend towards lower minimal FCV. In REM, the lowering of mean FCV was even more pronounced, but contrary to non-REM sleep without a shift of minimal and maximal FCV. Variations in F-tacheodispersion between sleep stages suggest that different supraspinal inhibitory neuronal circuits acting on the spinal motoneuron pool may contribute to muscle hypotonia in human non-REM sleep and to atonia in REM sleep.
