A Molecular Boron Cluster-Based Chromophore with Dual Emission

Bromination of the luminescent borane, anti-B18H22, via electrophilic substitution using AlCl3 and Br2 yields the monosubstituted derivative 4-Br-anti-B18H21 as an air-stable crystalline solid. In contrast to the unsubstituted parent compound, 4-Br-anti-B18H21 product possesses dual emission upon excitation with UV light and exhibits fluorescence at 410 nm and phosphorescence at 503 nm, with Фtotal = 0.07 in oxygen-free cyclohexane. Increased oxygen content in cyclohexane solution quenches the phosphorescence signal. The fluorescent signal intensity remains unaffected by oxygen, suggesting that this molecule could be used as a ratiometric oxygen probe.

Perspectiva dos condutores/maqueiros diante dos incidentes ocorridos no transporte de pacientes

RESUMOObjetivo: analisar os incidentes ocorridos durante o transporte intra-hospitalar dos pacientes na perspectiva dos condutores/maqueiros. Método: estudo quantitativo, exploratório, descritivo, realizado com 10 maqueiros de um hospital universitário. A coleta de dados foi realizada por meio de um formulário estruturado, com análise descritiva dos dados. Resultados: 60% dos trabalhadores relataram participação em cursos de capacitação; dentre os incidentes ocorridos durante o transporte intra-hospitalar, identificou-se a desconexão de O2 (oxigênio), de sonda, de equipo de soro, quebra de maca, paciente com parada cardíaca, crise de vômitos e quedas. Conclusão: os incidentes relatados pelos maqueiros, advindos do transporte do paciente, configuram-se em uma inconformidade com as diretrizes, pois colocam os trabalhadores em situação de vulnerabilidade a estes incidentes. Descritores: Segurança do Paciente; Gestão de Riscos; Acidentes; Assistência à Saúde; Profissional da Saúde; Indicador de Qualidade.ABSTRACTObjective: to analyze the incidents that occurred during the in-hospital transport of patients from the perspective of the handlers/stretchers-bearers. Method: this is a quantitative, exploratory, descriptive study, carried out with 10 nurses from a university hospital. The data collection was performed through a structured form, with a descriptive analysis of the data. Results: 60% of workers reported participation in training courses; among the incidents that occurred during intra-hospital transport, the disconnection of O2 (oxygen), probe, serum equipment, breakage of the stretcher, a patient with cardiac arrest, the crisis of vomiting and falls were identified. Conclusion: the incidents reported by the stretcher-bearers, arising from the patient's transportation, are in disagreement with the guidelines because they place workers in a situation of vulnerability to these incidents. Descriptors: Patient safety; Risk management; Accidents; Delivery of Health Care; Health Personnel; Quality Indicators.RESUMENObjetivo: analizar los incidentes ocurridos durante el transporte intra-hospitalario de los pacientes en la perspectiva de los conductores de camillas. Método: estudio cuantitativo, exploratorio, descriptivo, realizado con 10 conductores de maquilas de un hospital universitario. La recolección de datos fue realizada por medio de un formulario estructurado, con análisis descriptiva de los datos. Resultados: 60% de los trabajadores relataron participación en cursos de capacitación; dentro de los incidentes ocurridos durante el transporte intra-hospitalario, se identificaron la desconexión de O2 (oxígeno), de sonda, de equipo de suero, quiebra de la camilla, paciente con parada cardíaca, crisis de vómitos y caídas. Conclusión: los incidentes relatados por los conductores de camillas, em el transporte del paciente, se configura em una inconformidad con las diretrices, pues colocan a los trabajadores en situación de vulnerabilidad a estos incidentes.
