Estudo de natureza exploratória descritiva com abordagem quantitativa, avaliou a predisposição para o uso e abuso do álcool na Graduação em Enfermagem/UFRN. A amostra foi composta por 42 alunos regularmente matriculados, sendo 76% do gênero feminino. Utilizou-se o questionário CAGE acrescido de itens sobre a síndrome da abstinência alcoólica. Metade (50%) faz uso de álcool, com idade entre 21 e 22 anos (41%). O maior consumo está no quinto período (38%), seguido do terceiro (19%). Dentre os pesquisados, 34% sentem-se fisicamente mal após beberem, 33% tropeçam, cambaleiam e trançam as pernas, e 33% sentem calor e suam. No que se refere aos sintomas mentais e emocionais, 50% referiram lentidão do raciocínio, 25% sensações estranhas e assustadoras quando bebem, e 25%, perda da memória. Conclui-se que há predisposição para o uso e abuso do álcool, e uma tendência ao alcoolismo feminino.<br>El estudio de naturaleza exploratoria descriptiva con el acercamiento cuantitativo, evalu�� la predisposición para el uso y abuso del alcoholen la Graduación en enfermería /UFRN.

Half (50%) makes use of alcohol, with age among 21 to 22 years (41%). The largest consumption is in the fifth period (38%), following by the third period (19%) among researched them, 34% felt bad physically after having drunk, 33% trip, sway and braid the legs, and33% felt hot and sweat. In what refers to the mental and emotional symptoms, 50% referred slowness of the reasoning, 25% strange and frightening sensations when they drink, and 25% loss of the memory. It was ended that there is predisposition for the use and abuse of the alcohol and a tendency to the feminine alcoholism

O brincar em sala de espera de um Ambulatório Infantil: a visão dos profissionais de saúde

O objetivo deste estudo foi compreender, na perspectiva dos profissionais de saúde, o significado do uso do brincar/brinquedo em sala de espera de um ambulatório infantil. Realizaram-se entrevistas semiestruturadas com 11 trabalhadores. Procedeu-se à análise qualitativa dos dados, os quais foram organizados ao redor de dois temas: reconhecimento da importância do brincar/brinquedo e lidando com limitações. O brincar mostra-se como uma estratégia de cuidado à criança, pois ameniza o tempo de espera neste ambiente, altera positivamente o comportamento e valoriza o processo de desenvolvimento das mesmas, além de melhorar a comunicação e a interação com os profissionais da saúde. É preciso, entretanto, que exista uma estrutura física adequada do hospital, aliada aos profissionais de saúde e à equipe gestora sensíveis para a inclusão de novas estratégias de cuidado, a exemplo do brincar, a fim de humanizar a assistência à saúde da criança

Colonizing while migrating: How do individual enteric neural crest cells behave?

Background Directed cell migration is essential for normal development. In most of the migratory cell populations that have been analysed in detail to date, all of the cells migrate as a collective from one location to another. However, there are also migratory cell populations that must populate the areas through which they migrate, and thus some cells get left behind while others advance. Very little is known about how individual cells behave to achieve concomitant directional migration and population of the migratory route. We examined the behavior of enteric neural crest-derived cells (ENCCs), which must both advance caudally to reach the anal end and populate each gut region. Results The behaviour of individual ENCCs was examined using live imaging and mice in which ENCCs express a photoconvertible protein. We show that individual ENCCs exhibit very variable directionalities and speed; as the migratory wavefront of ENCCs advances caudally, each gut region is populated primarily by some ENCCs migrating non-directionally. After populating each region, ENCCs remain migratory for at least 24 hours. Endothelin receptor type B (EDNRB) signaling is known to be essential for the normal advance of the ENCC population. We now show that perturbation of EDNRB principally affects individual ENCC speed rather than directionality. The trajectories of solitary ENCCs, which occur transiently at the wavefront, were consistent with an unbiased random walk and so cell-cell contact is essential for directional migration. ENCCs migrate in close association with neurites. We showed that although ENCCs often use neurites as substrates, ENCCs lead the way, neurites are not required for chain formation and neurite growth is more directional than the migration of ENCCs as a whole. Conclusions Each gut region is initially populated by sub-populations of ENCCs migrating non-directionally, rather than stopping. This might provide a mechanism for ensuring a uniform density of ENCCs along the growing gut

Biological, environmental and socioeconomic threats to citrus lime production

Limes as a fruit crop are of great economic importance, key to Asian and South American cuisines and cultivated in nearlyall tropical and subtropical regions of the world. Demand for limes is increasing, driven by World Health Organizationrecommendations. Pests and pathogens have significantly reduced global productivity, while changes in agronomictechniques aim to alleviate this stress. We present here a holistic examination of the major biotic (pests and pathogens) andabiotic (environment and socioeconomic) factors that presently limit global production of lime. The major producers oflimes are India, China and Mexico, while loss of lime production in the United States from 2006 has led many countries inthe Western Hemisphere (Mexico, Costa Rica and Brazil) to export primarily to the USA. The most widespread inver-tebrate pests of lime areToxoptera citricidaandScirtothrips citri. Another insect,Diaphorina citri, vectors both Huan-glongbing (HLB) and Witches Broom of Lime, which are particularly destructive diseases. Developing agronomictechniques focus on production of resistant and pathogen-free planting materials and control of insect vectors. HLB infectscitrus in nearly all growing regions, and has been particularly devastating in Asian citrus. Meanwhile,Citrus tristeza virushas infected over 100 million citrus trees, mainly in the Americas and Mediterranean. Currently, Witches Broom Disease ofLime is localised to the Middle East, but recently it has been detected in South America. The range of its vectors (D. citriandHishimonus phycitis) further raises concerns about the potential spread of this disease. Abiotic threats to limeproduction are also a significant concern; key areas of lime production such as Mexico, India and the Middle East sufferfrom increasing water stress and high soil salinity, which combined with invasive pests and pathogens, may eliminate limeproduction in these areas. To ensure future security in lime production, policy makers, researchers and growers will need toexamine the potential of more resistant lime cultivars and establish novel areas of cultivation
