Estimating the thermoneutral zone for broiler breeders using behavioral analysis

Knowledge about bird's heat stress is extensively discussed in the literature. From behavior data collected during the summer of 2000/2001 in an open-sided reduced scale model of a poultry barn, this study estimated the thermoneutral zone for female broiler breeders. The birds were electronically identified and the frequency of use of passage, indicating movement, and drinker, indicating thirst, where the antennas were placed, was recorded. Environmental data such as dry and wet bulb temperature were collected in the geometric center of the model and continuously registered by a datalogger. From the statistical analysis, it was possible to predict a real-time-based zone where the birds showed coherent behavior towards the use of the drinker and movement in the passage.

Longitudinal behavioral analysis during dental care of children aged 0 to 3 years

Abstract: When and how the dentist intervenes have repercussions on children's physical and emotional patterns. The objective of the present study was to conduct a longitudinal behavioral analysis during dental care of babies aged 0 to 3 years. A total of 216 patients seen at the Baby Clinic of the School of Dentistry at Araçatuba, São Paulo State University (UNESP), were selected. The selection criterion was attendance at ten dental care sessions at bimonthly intervals for routine procedures such as clinical examination and oral hygiene. There was a predominance of cooperative behavior compared to uncooperative behavior when each visit was analyzed separately. The behavior of the patients must have been directly influenced by their psychomotor development. Constant attendance and exposure of the baby to non-stressful dental stimuli are factors that favor a cooperative behavior.

Prevalência de alterações locais e sistêmicas em indivíduos com disfunção temporomandibular

Temporomandibular disorder describes a variety of conditions including joint and muscle in the stomatognathic system, characterized by pain, TMJ sounds, functions irregular jaw and represent the leading cause of nondental pain in the orofacial region. The objective of this research was to evaluate the prevalence of ophthalmological, otological and cognitive-behavioral changes, parafunctional habits in individuals with temporomandibular disorders (TMD). A total of 117 medical records of female and male individuals, aged 18 to 60 years, from the Occlusion, Temporomandibular Dysfunction and Orofacial Pain of the Ribeirão Preto School of Dentistry – USP, between 2010 and 2011. The anamnesis index proposed by Helkimo was used to classify the individuals according to TMD severity degree and to divide them into two groups: AiI (mild to moderate) with 69 individuals and AiII (severe) with 48 individuals. The groups were then subdivided with respect to gender (72.64% female and 27.36% male) and age. There was predominance in the 18-40 year age group (60.68%) when compared to the 41-60 year age group (39.32%). Data were collected through an interview with questions about the presence of parafunctional habits, otological, ophthalmological and behavioral changes. Data were subjected to the statistical analysis using the Kruskal-Wallis test. The prevalence of each change was also evaluated. The results showed statistically significant for all groups according to gender, age and degree of severity. Individuals with temporomandibular disorders exhibited high prevalence of systemic and local dysfunctions.

Uma análise comportamentalista de relatos verbais e práticas educativas parentais: alcance e limites

O presente artigo discute a relevância de algumas estratégias metodológicas da Análise Aplicada do Comportamento para examinar práticas educativas parentais. Um instrumento e um conceito relacionados à coleta e análise de dados são discutidos sob a ótica teórica e aplicada: relatos verbais e análise funcional comportamental descritiva. Conclui-se que, consideradas as limitações dos relatos, as informações obtidas com essa estratégia e com a análise funcional comportamental descritiva permitem inferir algumas hipóteses sobre os comportamentos de pais e de filhos que podem ser utilizadas em ações que procuram investigar e intervir sobre os comportamentos problema e as habilidades sociais.

Treatment seeking by individuals with obsessive-compulsive disorder from the British Psychiatric Morbidity Survey of 2000

Objective: For several reasons, many individuals with obsessive-compulsive disorder (OCD) do not seek treatment. However, data on treatment seeking from community samples are scant. This study analyzed service use by adults with OCD living in private households in Great Britain. Methods: Data from the British Survey of Psychiatric Morbidity of 2000, in which 8,580 individuals were surveyed, were analyzed. Service use was compared for those with OCD, with other neuroses, with different subtypes of OCD (only obsessions, only compulsions, or both), and with OCD and comorbid neuroses. Results: Persons with OCD (N=114) were more likely than persons with other neuroses (N=1,395) to be receiving treatment (40% compared with 23%, p<.001). However, those with OCD alone (N=38) were much less likely than those with OCD and a comorbid disorder to be in treatment (14% compared with 56%, p<.001). In the previous year, 9.4% of persons with OCD had seen a psychiatrist and 4.6% had seen a psychologist. Five percent were receiving cognitive-behavioral therapy, 2% were taking selective serotonin reuptake inhibitors, and 10% were taking tricyclics. Conclusions: Most persons with OCD were not in contact with a mental health professional, and apparently very few were receiving appropriate treatments. Very few persons with noncomorbid OCD were receiving treatment. Individuals with OCD who are in treatment may not be disclosing their obsessions and compulsions and may be discussing other emotional symptoms, leading to inappropriate treatment strategies. Public awareness of OCD symptoms should be raised, and primary care professionals should inquire about them with all patients who have depressive or anxiety disorders.

Emetofobia: revisão crítica sobre um transtorno pouco estudado

INTRODUÇÃO: A emetofobia ou fobia de vômitos - que inclui o medo excessivo de vomitar ou de ver outras pessoas vomitando e pode ser desencadeado por estímulos internos e externos - é um transtorno mental complexo e pouco conhecido. OBJETIVO: Este estudo teve como objetivo levantar os conhecimentos disponíveis sobre diversos aspectos do quadro. MÉTODO: Revisão convencional da literatura dos últimos 30 anos utilizando como estratégia de busca as seguintes palavras-chave: emetofobia, emetofóbico, medo de vomitar, fobia de vomitar efobia de vômito. Foram incluídos artigos sobre epidemiologia, fenomenologia, diagnóstico diferencial e tratamento da emetofobia, assim como artigos referidos nestes. RESULTADOS: Não há dados de prevalência na população geral e pouco se sabe sobre a etiologia da emetofobia. A maioria dos estudos aponta predominância no sexo feminino, início precoce e curso crônico. Os comportamentos de esquiva podem impactar negativamente a vida ocupacional, social e familiar. Os principais diagnósticos diferenciais são: transtorno de pânico com agorafobia, fobia social, anorexia nervosa e transtorno obsessivo-compulsivo. Estudos de tratamento se resumem a relatos de casos e não há ensaios clínicos controlados, mas intervenções cognitivo-comportamentais parecem ser promissoras. CONCLUSÃO: Mais estudos são necessários para melhor compreensão sobre a epidemiologia, o quadro clínico, a etiologia, a classificação e o tratamento da emetofobia.

Tratamento do transtorno de pânico com terapia psicodramática de grupo

INTRODUÇÃO/OBJETIVOS: Há poucos trabalhos publicados sobre psicoterapia grupal para pacientes com transtorno de pânico (TP); além disso, esses estudos geralmente são restritos a abordagens cognitivo-comportamentais. O objetivo deste trabalho é relatar uma experiência de atendimento psicoterápico psicodramático grupal para portadores de TP, iniciada em 1996 na Faculdade de Medicina de Botucatu/Unesp, e discutir aspectos psicodinâmicos desse transtorno. MÉTODOS: Atende-se uma média de oito a dez pacientes em sessões mensais de duas horas de duração, nas quais se utilizam técnicas psicodramáticas. O uso associado de psicofármacos é a regra. A temática é aberta, centrando-se tanto em aspectos próprios do TP (sintomas mais comuns; peregrinação em serviços médicos até o diagnóstico; preocupações hipocondríacas; limitações e dependência; reações dos familiares; estratégias de exposição e enfrentamento; efeitos e reações dos medicamentos) quanto em problemas individuais específicos. RESULTADOS: A abordagem psicodramática favorece a identificação e a elaboração de aspectos psicodinâmicos. Entre estes, destacaram-se os sentimentos de desamparo e seus desdobramentos: insegurança; fragilidade e medo; raiva e culpa; sentimentos de desamor e rejeição; vergonha e inferioridade; isolamento e dificuldade de pedir ajuda; dificuldade de identificar e de expressar sentimentos - manifestados somaticamente -; e dificuldade de assumir o papel de cuidador e outras responsabilidades. CONCLUSÕES: Aspectos valiosos para o tratamento do TP, como apoio mútuo, companheirismo, confiança, modelo e estímulo, são favorecidos pelo contexto grupal homogêneo. O compartilhar de experiências e sofrimentos comuns propiciou rápida coesão e suporte grupal, melhora da capacidade de expressar sentimentos e da auto-estima e o aprimoramento de papéis sociais. Além da melhora dos sintomas, possibilitou-se a melhor compreensão e elaboração destes, que passam a ser integrados significativamente no contexto existencial.

Conceito de número: uma contribuição da análise comportamental da cognição

Fundamenta-se o presente estudo na análise comportamental da cognição, cujas formulações permitem compreender o conceito de número como uma rede de relações entre estímulos e/ou entre estímulos e respostas. O desempenho de seis crianças de três a sete anos de idade e uma adolescente portadora da Síndrome de Down foi analisado em uma série de tarefas consideradas pré-requisitos para aprendizagens matemáticas mais complexas. Para isso, foi utilizada uma versão informatizada do procedimento de discriminação condicional em um contexto de matching to sample. As relações presentes, ausentes e as não bem estabelecidas no repertório dos sujeitos foram graficamente representadas em diagramas que configuram-se como que retratos do repertório individual. Tal recurso facilita o planejamento do ensino estratégico de umas poucas relações com vistas à emergência das relações ausentes e/ou o fortalecimento daquelas nas quais o sujeito apresenta desempenho pobre, de modo a completar a rede. A guisa de conjeturas, apresentam-se sugestões de intervenção.

New guidelines for diagnosis and treatment of insomnia

The Brazilian Sleep Association brought together specialists in sleep medicine, in order to develop new guidelines on the diagnosis and treatment of insomnias. The following subjects were discussed: concepts, clinical and psychosocial evaluations, recommendations for polysomnography, pharmacological treatment, behavioral and cognitive therapy, comorbidities and insomnia in children. Four levels of evidence were envisaged: standard, recommended, optional and not recommended. For diagnosing of insomnia, psychosocial and polysomnographic investigation were recommended. For non-pharmacological treatment, cognitive behavioral treatment was considered to be standard, while for pharmacological treatment, zolpidem was indicated as the standard drug because of its hypnotic profile, while zopiclone, trazodone and doxepin were recommended.

Psicoterapia grupal no transtorno obsessivo-compulsivo

There are few published papers about group psychotherapy for patients with obsessive-compulsive disorder (OCD), and usually restricted psychoeducational, support or cognitive-behavioral approaches. This article describes the experience of group psychotherapy for OCD patients started in 1996 in Botucatu Medical School - Unesp, São Paulo, Brazil. The two-hour sessions occur once a month, with 6 to 10 female patients, and are based on psychodramatic techniques. Psychotropic prescriptions are given after the sessions. In the beginning, aggressive obsessions were more prominent and were reported with much anguish and shame. Gradually, the themes changed from OCD specific issues (symptoms, pharmacological treatment, outcome, need of exposure and response prevention) to deeper and more personal psychodynamic aspects. The psychodramatic approach (techniques of double, mirror, role inversion, search for prymary scenes) has mostly shown: difficulty in accepting their own human mistakes or negative emotions due to excessive personal demands. This seems to generate guilt, low self-esteem, idealization of others, difficulty in enjoying pleasant situations, fear of taking responsibilities and of losing control (madness/aggressiveness). The group has been considered very important by the patients, since sharing experiences helps to diminish feelings of isolation, shame and guilt, stimulates the exposure to feared situations and enhances self-esteem. The fact that all participants have the same disorder favors group cohesion and provides relief, as they see in the others some of their afflictions and are able to share similar feelings and experiences. Many times the burden of the symptoms are dealt with humor. The confidence in such therapeutic setting is helping the identification and resolution of personal conflicts and contributing to the adherence to pharmacological treatment. The group also provides valuable training experiences for resident physicians in psychiatry.

Predatory behavior of Canthon virens (Coleoptera: Scarabaeidae): A predator of leafcutter ants

We present a detailed description of the predatory behavior of the beetle Canthon virens Mannerheim, 1829, on the leafcutter ant Atta sp. We observed 51 acts of predation, which were also recorded on film and subjected to behavioral analysis. Canthon virens exhibited 28 behaviors while predating upon Atta sp. queens. Adult beetles search for queens while flying in a zigzag pattern, 15 to 20cm above the ground. After catching a queen, the predator stands on its back and starts cutting the queen cervix. Once the prey is decapitated, the predator rolls it until an insurmountable obstacle is reached. The distance from the site of predation to the obstacle can vary widely and is unpredictable. The beetle rolling the queen also buries it in a very peculiar way: first, it digs a small hole and pulls the queen inside, while another beetle is attached to the prey. The burial process takes many hours (up to 12) and may depend on the hardness of the soil and the presence of obstacles. In general, one or two beetles are found in a chamber with the queen after it is buried. They make the brood balls, which serve as food for the offspring. This study contributes to the knowledge of the predatory behavior of Canthon virens, a predator poorly studied in Brazil and widespread in the country. Copyright © 2012 Luiz Carlos Forti et al.
