Perspectivas de adolescentes e cuidadores sobre saúde mental e serviços

Objetivo: analisar os conceitos e percepções que adolescentes e seus cuidadores possuem sobre saúde mental e serviços de saúde em seu contexto ecológico e investigar as barreiras de acesso à assistência à saúde mental vivenciadas. Método: trata-se de estudo exploratório e analítico em amostra de conveniência obtida no período de outubro de 2009 a junho de 2010, com 100 adolescentes e 100 cuidadores, no município de Belém-PA, em dois contextos clínicos públicos, sendo um ambulatório especializado em saúde mental e um geral e dois contextos escolares, sendo um público e um privado. Utilizou-se questionários estruturados, para investigar diferentes dimensões envolvidas nas temáticas saúde, família, bem-estar e condições de vida, seguidos de análise estatística, com técnicas de análise da variância e correlacional. Resultados: a média das idades dos adolescentes foi de 14,47 (DP 1,90) anos, sendo 58% feminino; o tipo de problema de saúde mental relatado pela maioria foram problemas na escola (21,9%); o profissional mais frequentemente procurado foi o psicólogo (59,4%). No que tange as concepções de saúde mental, adolescentes e cuidadores deram importância ao comportamento de abster-se de drogas; quanto às concepções de doença mental, ambos, conceberam como algo a ser considerado com seriedade; ambos concordaram que a religião contribui para a saúde/doença mental e revelaram a primazia da mãe na busca de ajuda; no que tange as estratégias de coping os adolescentes lidavam de forma semelhante com os problemas de saúde mental em suas vidas; adolescentes e cuidadores possuíam uma visão estigmatizada do profissional de saúde e temores de discriminação principalmente pelos pares; quanto ao tratamento real ou imaginado ambos revelaram concepções favoráveis das terapias como fonte de ajuda e espaço privilegiado para expressar a própria opinião e em qualquer dos casos, a mãe revelou-se como a principal pessoa a contribuir na busca de ajuda especializada. As variáveis que revelaram a procedência das concepções sobre saúde/doença mental e as estratégias empregadas na manutenção da saúde mental da família mostraram diferenças entre os contextos investigados; no que tange ao auto conceito, os adolescentes da escola privada mostraram maior auto-congruência entre o self real e o ideal comparativamente os demais contextos; os cuidadores revelaram auto-congruência maior na escola pública. Quanto às perspectivas que o adolescente tem sobre a família revelaram identificações reais mais frequentes nos quatro contextos com a mãe, seguidas da avó/avô; quanto aos modelos de identificação familiar nos contextos clínicos e escola privada é maior com a mãe; na escola pública é maior com o pai; foi observado discrepância da perspectiva do cuidador acerca do conceito sobre o adolescente. Para a maioria dos adolescentes e cuidadores as condições de saúde foram classificadas de "boas" a "excelentes". A auto-avaliação do bem-estar dos adolescentes na amostra geral mostrou que, em sua maioria, sentiam-se muito satisfeitos, totalmente cheios de energia, divertiam-se e tiveram boa relação com os professores; na visão dos cuidadores, a maioria de seus adolescentes sentiam-se muito satisfeitos com a vida, utilizavam seu tempo livre divertindo-se com amigos e deram maior importância aos sentimentos de bem-estar com relação ao desempenho físico. Conclusões: são evidenciadas as semelhanças e diferenças entre adolescentes e cuidadores nas amostras clínicos e escolares que podem subsidiar ações preventivas de saúde contextualizadas para a cidade de Belém.

Physical education in schools, sport activity and total physical activity in adolescents

Less than half of adolescents reach the recommended 300 minutes per week of physical activity (PA). Physical education classes and sports participation provide opportunities for adolescents to accumulate more time for PA practice; however, little is known about the influence of these variables on the level of total physical activity of adolescents. The aim of this study was to investigate the association between the practice of physical education (PE) in schools and sports activities (SA) with the practice of total PA of adolescents. The study was cross-sectional and involved 467 adolescents of high school (15.8 ± 0.9 years-old) from the city of Rio Claro, in the State of São Paulo. Participants completed the Physical Activity Questionnaire to Older Children (PAQ-C) and questions related to the practice of PE and SA in schools. We performed a logistic regression with p<0.05 using SPSS. Girls had lower prevalence of PA than boys, 9.4% and 26.8%, respectively. Boys who did not participate of PE classes (OR=0.25, 95% CI=0.09-0.66) and SA in schools (OR=0.34, 95% CI=0.12-0.95) were less likely to be active in PA than boys who practiced these activities. The participation in PE classes or engagement in some SA were positively associated with the practice of total PA in boys.

Time needed to schedule dermatological consultations in Brazil

BACKGROUND: It is not clear what the population's demand for dermatologists is, nor how many professionals are needed in order to provide adequate care in this area of expertise. Knowledge of the flow of patients at dermatological clinics throughout the country allows for the formation of expansion and distribution policies regarding professionals, and provides backing for the decision to increase medical residency places. OBJECTIVES: To evaluate the time it takes to schedule a private dermatological consultation in Brazil, and other factors concerning consultations. METHODS: Survey with a random sample of 14% of Brazilian dermatologists, simulating the scheduling of emergency clinical and cosmetic consultations, and botulinum toxin procedures. Also, details relating to cost and professionals, were studied. Data were adjusted for each region of the country. RESULTS: A total of 873 dermatologists were evaluated. Full SBD members represented 85%, and 66% were women. The median time to schedule a consultation ranged from 6 (out-of-pocket payment) to 7 (medical insurance) consecutive working days. Times varied depending on the region. A multivariate analysis showed that out-of-pocket consultations and procedures were scheduled sooner than with medical insurance, regardless of whether they were clinical or cosmetic. CONCLUSION: The characteristics of dermatologists are varied throughout regions of the country. Private consultations and procedures are scheduled sooner than with insurance companies.

Tratamentos breves na psicanálise lacaniana: uma revisão sistemática de literatura

The paper outlines the profile of the scientific production about brief treatments based on the Lacanian Psychoanalysis. In order to accomplish this, the research focuses on online journals with free full-text articles written by members of Lacanian Schools listed on the website of the World Psychoanalysis Association. The work analyses studies from 2000 to 2009. In a total of 115 selected documents, the research has identified that online journals from Latin America contributed with 96 (83,47%) works. The literature review indicates that brief treatments are made possible by a construction of a specific mechanism, in which parameters of gratuity and limited time of care are established. However, a key conclusion from this review is that individual interventions with adults from big cities are still predominant.

From Sample Processing to Quantification: A Full Electrochemical Approach for Neutral Analyte Derivatization, Capillary Electrophoresis Separation, and Contactless Conductivity Detection

A thin-layer electrochemical flow cell coupled to capillary electrophoresis with contactless conductivity detection (EC-CE-(CD)-D-4) was applied for the first time to the derivatization and quantification of neutral species using aliphatic alcohols as model compounds. The simultaneous electrooxidation of four alcohols (ethanol, 1-propanol, 1-butanol, and 1-pentanol) to the corresponding carboxylates was carried out on a platinum working electrode in acid medium. The derivatization step required 1 min at 1.6 V vs. Ag/AgCl under stopped flow conditions, which was preceded by a 10 s activation at 0 V. The solution close to the electrode surface was then hydrodynamically injected into the capillary, and a 2.5 min electrophoretic separation was carried out. The fully automated flow system operated at a frequency of 12 analyses per hour. Simultaneous determination of the four alcohols presented detection limits of about 5 x 10(-5) mol As a practical application with a complex matrix, ethanol concentrations were determined in diluted pale lager beer and in nonalcoholic beer. No statistically significant difference was observed between the EC-CE-(CD)-D-4 and gas chromatography with flame ionization detection (GC-FID) results for these samples. The derivatization efficiency remained constant over several hours of continuous operation with lager beer samples (n = 40).

Real-time electrochemical determination of phenolic compounds after benzene oxidation

A sensitive electrochemical sensor was successfully developed on multi-walled carbon nanotubes (MWCNT) and cobalt phthalocyanine (CoPc) modified glassy carbon electrode (GC), and used to detect byproducts formed after the electrolysis of benzene. The GC/MWCNT/CoPc electrode was applied in the detection of phenolic compounds using square wave voltammetry (SWV). The proposed sensor exhibited a sequence in the sensitivity of the tested phenols: catechol > hydroquinone > resorcinol > phenol and 1,4-benzoquinone. The detection limits for individual phenols were also calculated: catechol (15.62 mu g L-1), hydroquinone (17.91 mu g L-1), resorcinol (46.12 mu g L-1), phenol (58.83 mu g L-1) and 1,4-benzoquinone (13.75 mu g L-1). The proposed sensor was successfully applied in the determination of the total amount of phenols formed after the benzene oxidation, and the obtained results were in full agreement with those from the HPLC procedure.

New Isomers in the Full Seniority Scheme of Neutron-Rich Lead Isotopes: The Role of Effective Three-Body Forces

The neutron-rich lead isotopes, up to Pb-216, have been studied for the first time, exploiting the fragmentation of a primary uranium beam at the FRS-RISING setup at GSI. The observed isomeric states exhibit electromagnetic transition strengths which deviate from state-of-the-art shell-model calculations. It is shown that their complete description demands the introduction of effective three-body interactions and two-body transition operators in the conventional neutron valence space beyond Pb-208.

Fuzzy Connectedness Image Segmentation in Graph Cut Formulation: A Linear-Time Algorithm and a Comparative Analysis

A deep theoretical analysis of the graph cut image segmentation framework presented in this paper simultaneously translates into important contributions in several directions. The most important practical contribution of this work is a full theoretical description, and implementation, of a novel powerful segmentation algorithm, GC(max). The output of GC(max) coincides with a version of a segmentation algorithm known as Iterative Relative Fuzzy Connectedness, IRFC. However, GC(max) is considerably faster than the classic IRFC algorithm, which we prove theoretically and show experimentally. Specifically, we prove that, in the worst case scenario, the GC(max) algorithm runs in linear time with respect to the variable M=|C|+|Z|, where |C| is the image scene size and |Z| is the size of the allowable range, Z, of the associated weight/affinity function. For most implementations, Z is identical to the set of allowable image intensity values, and its size can be treated as small with respect to |C|, meaning that O(M)=O(|C|). In such a situation, GC(max) runs in linear time with respect to the image size |C|. We show that the output of GC(max) constitutes a solution of a graph cut energy minimization problem, in which the energy is defined as the a"" (a) norm ayenF (P) ayen(a) of the map F (P) that associates, with every element e from the boundary of an object P, its weight w(e). This formulation brings IRFC algorithms to the realm of the graph cut energy minimizers, with energy functions ayenF (P) ayen (q) for qa[1,a]. Of these, the best known minimization problem is for the energy ayenF (P) ayen(1), which is solved by the classic min-cut/max-flow algorithm, referred to often as the Graph Cut algorithm. We notice that a minimization problem for ayenF (P) ayen (q) , qa[1,a), is identical to that for ayenF (P) ayen(1), when the original weight function w is replaced by w (q) . Thus, any algorithm GC(sum) solving the ayenF (P) ayen(1) minimization problem, solves also one for ayenF (P) ayen (q) with qa[1,a), so just two algorithms, GC(sum) and GC(max), are enough to solve all ayenF (P) ayen (q) -minimization problems. We also show that, for any fixed weight assignment, the solutions of the ayenF (P) ayen (q) -minimization problems converge to a solution of the ayenF (P) ayen(a)-minimization problem (ayenF (P) ayen(a)=lim (q -> a)ayenF (P) ayen (q) is not enough to deduce that). An experimental comparison of the performance of GC(max) and GC(sum) algorithms is included. This concentrates on comparing the actual (as opposed to provable worst scenario) algorithms' running time, as well as the influence of the choice of the seeds on the output.

Field and Laboratory Studies Provide Insights into the Meaning of Day-Time Activity in a Subterranean Rodent (Ctenomys aff. knighti), the Tuco-Tuco

South American subterranean rodents (Ctenomys aff. knighti), commonly known as tuco-tucos, display nocturnal, wheel-running behavior under light-dark (LD) conditions, and free-running periods >24 h in constant darkness (DD). However, several reports in the field suggested that a substantial amount of activity occurs during daylight hours, leading us to question whether circadian entrainment in the laboratory accurately reflects behavior in natural conditions. We compared circadian patterns of locomotor activity in DD of animals previously entrained to full laboratory LD cycles (LD12:12) with those of animals that were trapped directly from the field. In both cases, activity onsets in DD immediately reflected the previous dark onset or sundown. Furthermore, freerunning periods upon release into DD were close to 24 h indicating aftereffects of prior entrainment, similarly in both conditions. No difference was detected in the phase of activity measured with and without access to a running wheel. However, when individuals were observed continuously during daylight hours in a semi-natural enclosure, they emerged above-ground on a daily basis. These day-time activities consisted of foraging and burrow maintenance, suggesting that the designation of this species as nocturnal might be inaccurate in the field. Our study of a solitary subterranean species suggests that the circadian clock is entrained similarly under field and laboratory conditions and that day-time activity expressed only in the field is required for foraging and may not be time-dictated by the circadian pacemaker.

Comparison between frequency domain and time domain riser analysis

In the optimization or parametric analyses of risers, several configurations must be analyzed. It is laborious to perform time domain solutions for the dynamic analysis, since they are time-consuming tasks. So, frequency domain solutions appear to be a possible alternative, mainly in the early stages of a riser design. However, frequency domain analysis is linear and requires that nonlinear effects are treated. The aim of this paper is to present a possible way to treat some of these nonlinearities, using an iterative process together with an analytical correction, and compare the results of a frequency domain analysis with the those of a full nonlinear analysis.

Constraint-based analysis of gene interactions using restricted boolean networks and time-series data

Abstract Background A popular model for gene regulatory networks is the Boolean network model. In this paper, we propose an algorithm to perform an analysis of gene regulatory interactions using the Boolean network model and time-series data. Actually, the Boolean network is restricted in the sense that only a subset of all possible Boolean functions are considered. We explore some mathematical properties of the restricted Boolean networks in order to avoid the full search approach. The problem is modeled as a Constraint Satisfaction Problem (CSP) and CSP techniques are used to solve it. Results We applied the proposed algorithm in two data sets. First, we used an artificial dataset obtained from a model for the budding yeast cell cycle. The second data set is derived from experiments performed using HeLa cells. The results show that some interactions can be fully or, at least, partially determined under the Boolean model considered. Conclusions The algorithm proposed can be used as a first step for detection of gene/protein interactions. It is able to infer gene relationships from time-series data of gene expression, and this inference process can be aided by a priori knowledge available.
