Recommendations for monitoring avian populations with point counts: a case study in southeastern Brazil

No hemisfério norte, o censo de aves é fundamental para gerar informações que auxiliam na compreensão de tendências populacionais. Tais censos, devido à marcada sazonalidade deste hemisfério, são realizados durante dois momentos distintos: na estação reprodutiva (aves residentes) e no inverno (quando as aves migratórias deixam determinadas regiões). Na região neotropical, porém, dependendo da localidade, as aves podem se reproduzir durante qualquer ou vários períodos do ano; podem ou não migrar, e aquelas que o fazem podem apresentar um padrão assincrônico. Em contraste com o hemisfério norte, tendências populacionais são desconhecidas, bem como o impacto das taxas rápidas de urbanização e desmatamento, que também são pouco monitoradas. Para melhor entender padrões temporais de riqueza e abundância de aves, e avaliar como um censo similar pode ser implementado na América tropical, foram utilizados pontos de escuta ao longo de 12 meses em uma localidade no Estado de São Paulo, sudeste do Brasil. Os censos ocorreram duas vezes por dia (manhãs/tardes) em uma floresta semidecidual ao longo de transecções com 10 pontos (20 pontos por dia) distantes 200 m entre si e com raio de detecção limitado em 100 m. Ambas as riquezas e abundâncias de aves foram maiores durante as manhãs, mas as curvas de acumulação sugerem que os censos vespertinos com maior esforço amostral podem fornecer resultados similares aos censos matutinos. Riqueza e abundância das aves não variam de acordo com estações (i.e., sem padrão aparente entre reprodução e migração), enquanto espécies exclusivas foram encontradas todos os meses e relativamente poucas espécies (20%) foram registradas em todos os meses do ano. Durante este ano, 84% de todas as aves florestais da área estudada foram registradas. Sugerimos que a metodologia de pontos de escuta pode ser utilizada à semelhança dos censos do hemisfério norte. Recomendamos ainda que o esforço amostral em transecções deva incluir ao menos 20 pontos, e que o início da contagem das aves deva ser sazonal, utilizando o período de migração das espécies austrais (e os seis meses seguintes) para coordenar pontos de escuta. Por último, sugerimos que os censos no Brasil e até mesmo na América Latina podem ajudar no entendimento de tendências populacionais, mas também demandam maior esforço do que o observado em latitudes temperadas, devido à maior riqueza de espécies e diferenças nas dinâmicas de reprodução e migração. Por meio do uso de censos de aves coordenados poderá ser desenvolvida uma técnica para os trópicos que irá gerar informações que permitam acompanhar tendências populacionais, com benefícios para a conservação das aves, similarmente aos censos realizados em países do hemisfério norte.

Characterization of the intrahospital transport of critically ill patients

Objective: Characterizing the transport of critically ill patients in an adult intensive care unit.Methods: Cross-sectional study in which 459 intra -hospital transports of critically ill patients were included. Data were collected from clinical records of patients and from a form with the description of the materials and equipment necessary for the procedure, description of adverse events and of the transport team.Results: A total of 459 transports of 262 critically ill patients were carried out, with an average of 51 transports per month. Patients were on ventilatory support (41.3 %) and 34.5 % in use of vasoactive drugs. Adverse events occurred in 9.4% of transports and 77.3 % of the teams were composed of physicians, nurses and nurse technicians.Conclusion: The transport of critically ill patients occurred in the morning period for performing computerized tomographies (CT scans) with patients dependent on mechanical ventilation and vasoactive drugs. During the transports the equipment was functioning, and the adverse events were attributed to clinical changes of patients.

Fluticasone/formoterol dry powder versus budesonide/formoterol in adults and adolescents with uncontrolled or partly controlled asthma

This 12-week study compared the efficacy and safety of a fixed combination of fluticasone propionate plus formoterol (FL/F) 250/12 mu g b.i.d. administered via a dry powder inhaler (DPI) (Libbs Farmaceutica, Brazil) to a combination of budesonide plus formoterol (BD/F) 400/12 mu g b.i.d. After a 2-week run-in period (in which all patients were treated exclusively with budesonide plus formoterol), patients aged 12-65 years of age (N = 196) with uncontrolled asthma were randomized into an actively-controlled, open-labeled, parallel-group, multicentre, phase III study. The primary objective was to demonstrate non-inferiority, measured by morning peak expiratory flow (mPEF).The non-inferiority was demonstrated. A statistically significant improvement from baseline was observed in both groups in terms of lung function, asthma control, and the use of rescue medication. FL/F demonstrated a statistical superiority to BD/F in terms of lung function (FEV1) (p = 0.01) and for asthma control (p = 0.02). Non-significant between-group differences were observed with regards to exacerbation rates and adverse events.In uncontrolled or partly controlled asthma patients, the use of a combination of fluticasone propionate plus formoterol via DPI for 12-weeks was non-inferior and showed improvements in FEV1 and asthma control when compared to a combination of budesonide plus formoterol.

Comportamento ingestivo de bovinos mantidos em pastos de Brachiaria brizantha cv. Xaraés manejado em diferentes alturas de pastejo

This experiment was conducted to evaluate the effect of grazing heights on daytime behavioral activities of Nellore beef cattle in the rainy season. The experimental area was 12 hectares divided into paddocks of one hectare each. The treatments consisted of four defoliation heights (15, 30, 45 and 60 cm) in pastures of Brachiaria brizantha cv. Xaraes with three replicates each. It was used the continuos grazing method, with variable stocking rate. Forage samples collected on the plots were sent to the laboratory for separation of the botanical components, weighing and determination of dry matter, with the material collected by simulated grazing. The variables: grazing time, idle time and ruminating time were evaluated for 12 consecutive hours on days 15 and 16 February 2011, considering the morning and afternoon periods. It was used a completely randomized design. The height of the canopy significantly influenced the daily grazing time and ruminating time, with a quadratic response as a function of time of defoliation. The bite rate decreased as a function of heights studied. However the chemical composition of the material collected by simulated grazing did not differ between treatments. Xaraes grass swards grazed at around 45 cm height provide greater ease of apprehension by grazing cattle.

Eventos adversos em terapia medicamentosa em Unidade de Terapia Intensiva - UTI

Due to the complexity and instability of clinical conditions of ICU patients, the drug therapy applied in this type of environment requires a combination of several prescribed drugs, which is a favorable condition for drug interaction, toxic synergism and possible iatrogenia. In the possible universe of ICU occurrences, this study aimed at identifying and evaluating the incidence of adverse events in drug therapy at the Intensive Care Therapy Service (SETI) in wards I and II. It is a cross-sectional, descriptive, prospective and quantitative study conducted from August to September, 2011 in the Intensive Care Service of the Botucatu School of Medicine University Hospital - UNESP. The population consisted of fifteen clinical nurses, including those in the Improvement and Volunteer Internship Programs, who contributed to the investigation after signing an informed consent form and according to approval by the Research Ethics Committee number 10711/CE - FMB. The data were entered on a form and analyzed. Results showed that, on average, 8.9% of events/day occurred, and the highest frequency was observed on August 04, 2011. 63% and 22% were respectively observed in the morning and afternoon shifts, and 15% in the night shift. 48% of these were due to administration time errors, followed by drug prescription and dispensation errors, with percentages of 22% and 18%, respectively. Antibiotics showed the highest frequency of adverse events - 18%, which was followed by 13% for anticoagulant, 11% for antiemetic and 10% for antiulcerative drugs. As regards the occurrence of adverse events related to hospitalization time, the highest frequency occurred in patients who were hospitalized for 10 days. Concerning the ratio between reported events and the number of items in the prescription, the highest frequency of events was related to prescriptions with 20 items...
