    áveis, portadores de DPOC e hipoxemia leve (saturação de oxigênio = 90-94%) em um centro clínico especializado no atendimento de doenças respiratórias em Goiânia (GO). Os pacientes foram submetidos à avaliação clínica, espirometria, polissonografia, ecocardiografia, gasometria arterial, teste de caminhada de seis minutos e radiografia de tórax. Foram avaliados 64 pacientes com DPOC e hipoxemia leve, e 39 (61%) apresentaram distúrbios respiratórios do sono (14 com AOS e 25 com hipoxemia noturna isolada). A análise de correlação mostrou moderada correlação da PaO2 com saturação média do sono (r = 0,45; p = 0,0002), saturação média do sono rapid eye movement (REM; r = 0,43; p = 0,001) e saturação média do sono não-REM (r = 0,42; p = 0,001). Um ponto de corte de PaO2 ≤ 70 mmHg (OR = 4,59; IC95%: 1,54-13,67; p = 0,01) na gasometria arterial foi significativamente associada com distúrbios respiratórios do sono. O modelo mostrou que, para identificar distúrbios respiratórios do sono, o ponto de corte teve uma especificidade de 73,9% (IC95%: 51,6-89,8%), uma sensibilidade de 63,4% (IC95%: 46,9-77,9%) e valores preditivos positivo e negativo de 81,3% (IC95%: 67,7-90,0%) e 53,1% (IC95%: 41,4-64,4%), respectivamente. A área sob a curva ROC foi de 0,69 (IC95%: 0,57-0,80), e a proporção de observações corretamente classificadas foi de 67,2% dos casos. A elevada prevalência de distúrbios respiratórios do sono em portadores de DPOC e hipoxemia leve nesta amostra (61%) sugere que esses pacientes podem se beneficiar da realização de estudos do sono.

    It is suspected that prolactin may affect mohair growth; therefore, effects of infusing prolactin on mohair growth were investigated using a skin perfusion technique. Seven Angora wethers (average body weight, 30 +/- 3 kg) were implanted bilaterally with silicon catheters into the superficial branches of the deep circumflex iliac artery and vein. For the first 14 d of the experiment, animals were infused (2.4 mL/h) with prolactin (one side) or control (other side) into the deep circumflex iliac arteries. The infusion rate of prolactin was 2.21 mg/d and was calculated to triple prolactin blood concentration in the perfused region. The area of skin supplied by the deep circumflex iliac artery was approximately 240 cm2. Two weeks after the cessation of infusions, 100-cm2 areas within the perfused regions were shorn to determine mohair growth. Greasy and clean mohair production was decreased (P < 0.05) by prolactin compared with control (3.79 vs 4.62 and 3.02 vs 3.67 g/[100 cm2 x 28 d], respectively). Oxygen satura tion in blood hemoglobin from the deep circumflex iliac veins was greater (P < 0.02) on the side infused with prolactin than on the control side (75.1 vs 68.2%). Higher concentrations of methionine, lysine, valine, isoleucine, and leucine were observed in blood of the deep circumflex iliac vein on the side infused with prolactin vs that infused with control (P < 0.05). In conclusion, direct skin infusion with prolactin decreased mohair fiber synthesis by the skin and may have concomitantly lessened oxygen consumption. Thus, effects of increasing prolactin concentration approximately two-fold in the skin on mohair fiber growth may not be limited to simple competition for nutrients between skin and other tissues such as the mammary gland.

    Evaluate the perception of nurses regarding interpersonal communication while providing care via telehealth. Qualitative research realized with seven nurses working in telehealth in Brazil, the sample was determined by data saturation. A questionnaire with open questions was applied and then content analysis of the dialogues was conducted, focusing on thematic analysis. Four categories emerged from the dialogues: Understanding the importance of communication; the interpersonal relationship interfering with communication; Communicating via technology; and Learning the communication process. The perception of nurses working in telehealth in Brazil is that technology has facilitated their professional practice; however, in relation to the communication process, they believe it is harder to communicate by telehealth, mainly due to difficulty in perceiving nonverbal signals. To overcome these difficulties, they agreed that interpersonal communication is a skill that must be acquired during their professional training. Avaliar a percepção do enfermeiro referente à Comunicação interpessoal no cuidado por telessaúde. Pesquisa qualitativa, realizada com sete enfermeiros que atuam em telessaúde no Brasil, com amostra determinada pela saturação de dados. Aplicou-se um questionário com perguntas abertas e foi realizada análise de conteúdo dos discursos, com enfoque na análise temática. Dos discursos emergiram quatro categorias: Entendendo a importância da comunicação; O relacionamento interpessoal interferindo na comunicação; Comunicando-se por meio da tecnologia; e Aprendendo o processo de comunicação. A percepção dos enfermeiros que atuam em telessaúde no Brasil é de que a tecnologia tem facilitado sua prática profissional; porém, em relação ao processo de comunicação, creem que seja mais difícil se comunicar pela telessaúde, principalmente devido à dificuldade de percepção de sinais não verbais. Para superar essas dificuldades, concordam

    To evaluate the acute effects of maternal and fetal hemodynamic responses in pregnant women submitted to fetal Doppler and an aerobic physical exercise test according to the degree of effort during the activity and the impact on the well-being. Transversal study with low risk pregnant women, obtained by convenience sample with gestational age between 26 to 34 weeks. The participants carry out a progressive exercise test. After the exercise session, reduced resistance (p=0.02) and pulsatility indices (p=0.01) were identified in the umbilical artery; however, other Doppler parameters analyzed, in addition to cardiotocography and fetal biophysical profile did not achieve significant change. Maternal parameters obtained linear growth with activity, but it was not possible to establish a standard with the Borg scale, and oxygen saturation remained stable. A short submaximal exercise had little effect on placental blood flow after exercise in pregnancies without complications, corroborating that healthy fetus maintains homeostasis even in situations that alter maternal hemodynamics. Avaliar os efeitos agudos de respostas hemodinâmicas maternas e fetais em gestantes submetidas a Doppler fetal e a um teste de exercício físico aeróbio, de acordo com o grau de esforço durante a atividade e o impacto sobre o bem-estar.

    Introdução: A sépsis severa e o choque sético são entidades clínicas frequentes com elevada morbi-mortalidade que superam os da doença cardíaca coronária ou do acidente vascular cerebral. A realidade da sépsis tratada no hospital fora das unidades de cuidados intensivos é amplamente desconhecida. Pretende-se neste trabalho estimar o cumprimento da bundle das 6-horas da Surviving Sepsis Campaign num serviço de urgência português e os resultados clínicos dos doentes. Material e Métodos: Estudo retrospetivo, observacional de coorte com 178 pacientes com sépsis severa/choque sético internados na unidade de cuidados intensivos e intermédios entre 1 de Janeiro de 2012 e 31 de Dezembro de 2012. Resultados: Durante o período estudado foi diagnosticado choque sético em 100 pacientes (56,2%) e sépsis severa em 78 pacientes (43,8%). O cumprimento com a bundle foi: (1) 62,9% para a medição de lactatos; (2) 62,9% para a colheita hemoculturas antes da antibioterapia; (3) 41,6% para a administração de antibióticos nas primeiras 3 horas; (4) 76,4% para a administração de fluidos; (5) 25% para a administração de vasopressores; (6) 37% for medição da pressão venosa central; (7) 39% para a medição da saturação venosa central de oxigénio. O cumprimento de todas as medidas foi observado em 22% dos pacientes. A medida 'colheita hemoculturas antes da antibioterapia' esteve significativamente associada a um menor risco de mortalidade na unidade de cuidados intensivos e aos 28 dias. Também se verificou uma tendência para uma correlação inversa entre cumprimento crescente da bundle e a mortalidade na unidade de cuidados intensivos e aos 28 dias. Discussão: A baixa adesão à bundle das 6-horas da Surviving Sepsis Campaign é um resultado que replica o de estudos internacionais semelhantes. A explicação para este fenómeno é complexa mas pode incluir a falta de monitorização da qualidade dos cuidados no serviço de urgência. Conclusões: O

  12. Soil aggregate stability as an indicator for eco-engineering effectiveness?

    have been performed in order to bridge this gap addressing partic-ularly the influence of root growth and mycorrhizal fungi on the resistance of soil aggregates against disintegration and linking it to slope stability. As superficial soil failure is often related to heavy rainstorms and, in this regard, mainly due to water satura-tion, recent investigations focused on the pore water pressure, too. Summarising main results of the different studies a positive relationship between soil aggregate stability and traditional soil mechanical shear strength parameters was found, e.g. given certain soil conditions, an increase in aggregate stability may be equated to an increase of the angle of internal friction Φ' and/or cohesion c'. In addition, almost all investigations showed a strong positive correlation between root length per soil volume and soil aggregate stability. In respect of mycorrhizal fungi, results are not yet as clear. On the one hand it was found that the use of unspecific (commercial) inoculum had no or even a negative effect on root growth within the first vegetation period and, correspondingly, on soil aggregate stability. However, the use of specific plant fungi combinations almost ever resulted in an obvious acceleration of root growth immediately with con-comitant gain of soil stability. As far as pore water pressure is concerned we did not yet find an interpretation that is fairly straightforward and not overly prone to controversy. It looks like soil aggregated by mycorrhized plants does have a higher capacity for building up pressure than such permeated by non-mycorrhized roots. Within this scope results of several studies showing these (inter-) relationships and correlations are presented and differences as well as unexpected results discussed.

    sessão de hemodiálise. Trinta pacientes foram randomizados para realizar exercício aeróbio com cicloergômetro para membros inferiores durante 30 minutos com intensidade entre 60-70% da frequência cardíaca máxima, ou grupo controle (GC). Amostras sanguíneas foram coletadas antes e imediatamente após o término do exercício ou no período equivalente no GC. Análises da bioquímica do sangue e dialisato e gasometria foram realizadas. A massa removida e a depuração dos solutos foram calculadas. O estresse oxidativo foi determinado pela peroxidação lipídica e capacidade antioxidante total. As concentrações séricas dos solutos aumentaram com o exercício, mas somente o fósforo mostrou elevação significativa (p = 0.035). Não houve modificações significantes na remoção de solutos e no equilíbrio ácido-básico. A pressão parcial e a saturação de oxigênio aumentaram com o exercício (p = 0.035 e p = 0.024, respectivamente), o que não ocorreu no GC. A capacidade antioxidante total diminuiu significativamente (p = 0.027). O exercício aeróbico intradialítico agudo aumentou a concentração sérica de fósforo e diminuiu a capacidade antioxidante total, revertendo a hipoxemia resultante da hemodiálise. O exercício intradialítico não alterou o equilíbrio ácido-básico e a remoção de solutos.
