JUVENILE DEVELOPMENT OF DILOCARCINUS PAGEI STIMPSON, 1861 (BRACHYURA, TRICHODACTYLIDAE) REARED IN THE LABORATORY, WITH EMPHASIS ON SETAE MORPHOLOGY

The juvenile development of the freshwater crab Dilocarcinus pagei Stimpson, 1861 was studied under laboratory conditions, focusing on setae morphology. The ovigerous females were collected manually associated with water hyacinth at the Municipal Dam of Sao Jose do Rio Preto (Sao Paulo, Brazil). The specimens were raised in the laboratory under constant aeration, photoperiod (12: 12 h) and temperature (27 +/- 1 degrees C). Twelve juvenile stages were obtained with descriptions of the main morphological characters that allow their identification are presented. Fourteen types of setae were discovered: dentate, denticulate, serrulate, papposerrate, cuspidate, plumose, plumodenticulate, plumoserrulate, simple, pappose, brush, curved, nail and setules. The greatest diversity of setae was found on the mouth appendages, especially the maxillule. The gill ontogeny and sexual dimorphism becomes apparent from the second juvenile stage onwards. At the third juvenile stage, the carapace begins to exhibit a wider shape, becoming similar to that of the adults.

Emotional assessment of patients with oral lichen planus

Background Oral lichen planus is a chronic immune-mediated disease with an estimated prevalence of 0.5-2.5% in the general population. Patients with oral lichen planus are often emotionally unstable and anxious and may develop concomitant systemic disorders. The objective of this study was to evaluate emotional characteristics of patients with oral lichen planus.Methods Two groups were studied: the first group consisted of 48 patients with a diagnosis of oral lichen planus, and the second group consisted of controls without the disease matched for age and gender at a proportion of 1 : 1. The emotional state of the patients was evaluated using the State-Trait Anxiety Inventory, SF-36 generic quality of life questionnaire, and the Self Reporting Questionnaire-20.Results and conclusions The present investigation demonstrated the presence of anxiety and depression in patients with oral lichen planus and a negative impact of the disorder on the patient's quality of life as indicated by impairment of the physical aspect, vitality, mental health, and social aspect domains. This could indicate that associated psychological treatment may be important in the follow-up of these patients.

Fatores de risco para complicações respiratórias após adenotonsilectomia em crianças com apneia obstrutiva do sono

Identificar fatores de risco para complicações respiratórias após adenotonsilectomia em crianças ≤ 12 anos com apneia obstrutiva do sono encaminhadas à UTI pediátrica (UTIP). Estudo de coorte histórica com corte transversal que analisou 53 crianças após adenotonsilectomia que preencheram os critérios pré-estabelecidos para encaminhamento à UTIP em um hospital escola de nível terciário. Foram utilizados o teste t de Student, o teste de Mann-Whitney e o teste do qui-quadrado para identificar os fatores de risco. Das 805 crianças submetidas à adenotonsilectomia entre janeiro de 2006 e dezembro de 2012 no hospital escola, 53 foram encaminhadas à UTIP. Vinte e uma crianças (2,6% do total de submetidas à adenotonsilectomia e 39,6% das que foram encaminhadas à UTIP) apresentaram complicações respiratórias, sendo 12 do gênero masculino e a idade média de 5,3 ± 2,6 anos. Maior índice de apneia-hipopneia (IAH; p = 0,0269), maior índice de dessaturação de oxigênio (IDO; p = 0,0082), baixo nadir da SpO2 (p = 0,0055), maior tempo de intubação orotraqueal (p = 0,0011) e rinopatia (p = 0,0426) foram preditores independentes de complicações respiratórias. Foram observadas complicações respiratórias menores (SpO2 entre 90-80%) e maiores (SpO2 ≤ 80%, laringoespasmos, broncoespasmos, edema agudo de pulmão, pneumonia e apneia). Em crianças de até 12 anos e com apneia obstrutiva do sono, aquelas que têm maior IAH, maior IDO, menor nadir da SpO2 e/ou rinopatia são mais predispostas a desenvolver complicações respiratórias após adenotonsilectomia do que aquelas sem essas características.

Centriole behaviour during meiosis of male germ cells of Dermatobia hominis (Diptera:Cuterebridae)

During the meiotic division of Dermatobia hominis spermatogenesis, the centrioles duplicate only in prophase I, giving rise to short cilia which are exposed on the cellular surface. In metaphase I they are internalized and distributed to the daughter cells. Consequently, the secondary spermatocytes have two centrioles which repeat the cycle of cilia externalization followed by internalization. The spermatids receive only one centriole, which changes into a basal body and originates a flagellum. This centriole behaviour seems to be a general feature in insect male germ cell meiosis.

Are biological species and higher-ranking categories real? Fish folk taxonomy on Brazil`s Atlantic Forest coast and in the Amazon

Analysis of Brazilian fishers` classifications of 24 marine (Atlantic coast) and 24 freshwater (Amazon) fish species reveals that fishers from the Atlantic coast identify fish mainly through generic names (primary lexemes), while riverine Amazonian fishers typically identify them through binomials. The similarity of Amazonian fish species seems to contribute to the detailed folk taxonomy used by riverine fishers. High-ranking groups called ""relatives"" or ""cousins"" are sorted by fishers in terms of similarities of habitat, diet, and morphology and, secondarily, behavior. The general correspondence between the folk and scientific taxonomies reinforces the reality of both the supracategories used by these fishers and the biological groups as discontinuities in nature. Given the urgency of biological inventories and the lack of knowledge of high-biodiversity environments such as the Atlantic Forest and the Amazon, these results suggest that fisher knowledge and experience could contribute to scientific research.

Role of common mental and physical disorders in partial disability around the world

Background Mental and physical disorders are associated with total disability, but their effects on days with partial disability (i.e. the ability to perform some, but not full-role, functioning in daily life) are not well understood. Aims To estimate individual (i.e. the consequences for an individual with a disorder) and societal effects (i.e. the avoidable partial disability in the society due to disorders) of mental and physical disorders on days with partial disability around the world. Method Respondents from 26 nationally representative samples (n=61 259, age 18+) were interviewed regarding mental and physical disorders, and day-to-day functioning. The Composite International Diagnostic Interview, version 3.0 (CIDI 3.0) was used to assess mental disorders; partial disability (expressed in full day equivalents) was assessed with the World Health Organization Disability Assessment Schedule in the CIDI 3.0. Results Respondents with disorders reported about 1.58 additional disability days per month compared with respondents without disorders. At the individual level, mental disorders (especially post-traumatic stress disorder, depression and bipolar disorder) yielded a higher number of days with disability than physical disorders. At the societal level, the population attributable risk proportion due to physical and mental disorders was 49% and 15% respectively. Conclusions Mental and physical disorders have a considerable impact on partial disability, at both the individual and at the societal level. Physical disorders yielded higher effects on partial disability than mental disorders.

Internacionalização pelo Envolvimento de Atores Externos no Conflito Colombiano: Atuação da OEA na Desmobilização de Grupos Paramilitares na Colômbia

Internationalization of the Colombian Conflict by the Involvement of External Actors: Action by the OAS in Demobilizing Paramilitary Groups in Colombia This paper discusses the effects of the internationalization of the Colombian armed conflict, understood as the participation of foreign actors in programs regarding the resolution of the conflict. Through an analysis of the involvement of multilateral and state actors, the authors argue that this process involved the dilemma between unilateralism and multilateralism. The empirical analysis is centered on the intervention of conflict mediation mechanisms from the Organization of American States (OAS), specifically the Mission to Support the Peace Process (MAPP/OAS), whose scope is aimed at demobilizing paramilitary groups in Colombia.

THE KNOWLEDGE ABOUT COMMUNICATION STRATEGIES WHEN TAKING CARE OF THE EMOTIONAL DIMENSION IN PALLIATIVE CARE

The aim of this qualitative study was to investigate existing knowledge and the use of communication strategies in emotional care for patients receiving palliative care in Brazil. It was performed from August, 2008, to July, 2009, with 303 health professionals who worked or had frequent contact with patients receiving palliative care, using a questionnaire. Data was submitted to descriptive and analytical statistical treatment. The professionals reported not knowing about communication strategies, showing a significant difference (p-value 0.0011) in comparing subjects with and without previous training in palliative care, showing that those who had received proper training know/use more communication strategies when providing care for their patients on an emotional level. The strategies most often cited were: careful listening, verbal reaffirmation of care, using open questions, and affective touch. We conclude that there is little knowledge and poor use of communication strategies among health professionals in towards the emotional care of patients receiving palliative care.
