An agenda for rethinking mid-career master programs in public administration

The pace of societal change and the development of societal challenges have speeded up considerably during the last couple of decades, with substantial impact on different levels, i.e. ranging from global to local, or from business to government. When focusing on the public domain, these changes and challenges have had a major impact on public professionals, who face different and frequently changing questions. Mid-career programs in Public Administration (MPA) have the mission to support enrolled professionals in dealing with these changes and challenges. This article is about the development of such MPAs. Both substantive and didactic development is needed. To counter institutional inertia it seems vital to institutionalize a regular rethinking and adaptation of curricula and didactic strategies. This article identified some important points of attention and some options to deal with these in order to continuously improve the contribution of MPA programs to relevant and effective professional development and ongoing professional learning

Increased hippocampal CA1 density of serotonergic terminals in a triple transgenic mouse model of Alzheimer's disease: an ultrastructural study

Alzheimer's disease (AD) is a neurodegenerative pathology that deteriorates mnesic functions and associated brain regions including the hippocampus. Serotonin (5-HT) has an important role in cognition. We recently demonstrated an increase in 5-HT transporter (SERT) fibre density in the hippocampal CA1 in an AD triple transgenic mouse model (3xTg-AD). Here, we analyse the ultrastructural localisation, distribution and numerical density (Nv) of hippocampal SERT axons (SERT-Ax) and terminals (SERT-Te) and their relationship with SERT fibre sprouting and altered synaptic Nv in 3xTg-AD compared with non-transgenic control mice. 3xTg-AD animals showed a significant increase in SERT-Te Nv in CA1 at both, 3 (95%) and 18 months of age (144%), being restricted to the CA1 stratum moleculare (S. Mol; 227% at 3 and 180% at 18 months). 3xTg-AD animals also exhibit reduced Nv of perforated axospinous synapses (PS) in CA1 S. Mol (56% at 3 and 52% at 18 months). No changes were observed in the Nv of symmetric and asymmetrical synapses or SERT-Ax. Our results suggest that concomitant SERT-Te Nv increase and PS reduction in 3xTg-AD mice may act as a compensatory mechanism maintaining synaptic efficacy as a response to the AD cognitive impairment

Dissolved trace elements and heavy metals in the Danjiangkou Reservoir, China

Concentrations of trace elements and heavy metals (Al, As, Ba, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Sb, Se, Sr, V and Zn) in the Danjiangkou Reservoir, the water source area of the Middle Route of China’s interbasin South to North Water Transfer Project, were analyzed using an Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) and compared with the national and international standards for drinking water. The results indicated that concentrations of As, Pb, Sb and Se in the Reservoir exceeded the standards and they would pose health risk for residents in the region and the water receiving areas of the interbasin water transfer project. Spatial and temporal variability of the trace elements and heavy metals in the Reservoir implies their mixed sources of natural processing and anthropogenic activities in the upper drainage of the Reservoir. The research results would help develop water resource management and conservation strategy for the interbasin water transfer project

Aspectos técnicos da monitorização da pressão intracraniana pelo método subaracnóideo no traumatismo craniencefálico grave Technical aspects of intracranial pressure monitoring by subarachnoid method in severe head injury

Foram analisados prospectivamente 206 pacientes com traumatismo craniencefálico (TCE) grave (8 pontos ou menos na Escala de Coma de Glasgow), internados na Unidade de Terapia Intensiva do Hospital das Clínicas da Universidade Estadual de Campinas. Após avaliação por tomografia computadorizada de crânio (TC), 72 pacientes necessitaram de tratamento neurocirúrgico. Todos os pacientes foram submetidos à monitorização contínua da pressão intracraniana (PIC) pelo método subaracnóideo (11 com parafuso metálico e 195 com cateter plástico). Os níveis de PIC foram registrados continuamente na tela do monitor, sendo os seus valores de final de hora anotados em ficha padronizada. Todos os pacientes foram tratados segundo um protocolo orientado pelos níveis da PIC. Não foram observadas complicações hemorrágicas ou hematomas intracranianos relacionados ao método de monitorização em TC de controle. Para controle de infecções intracranianas, foram colhidas amostras de líquido cefalorraquidiano através de punção lateral C1-C2 em 66 pacientes com PIC abaixo de 20 mm Hg, sendo positivas as culturas para Acinetobacter sp em 2 pacientes. O resultado final na alta hospitalar mostrou 75 (36,40%) óbitos e 131 (63,6%) sobreviventes. Os níveis de PIC influenciaram significativamente o resultado final (p<0,001), o que confirma a importância de sua monitorização e controle no tratamento do TCE grave. O método subaracnóideo para a monitorização contínua da PIC foi considerado aplicável, seguro, simples, de baixo custo e útil para a orientação do tratamento. A metodologia de registro da PIC foi considerada útil e prática. Apesar dos avanços técnicos nesta área, o método subaracnóideo mostrou-se uma alternativa bastante viável para a monitorização da PIC em pacientes com traumatismo craniencefálico grave.<br>Two hundred and six patients with severe head injury (Glasgow Coma Scale of 8 points or less after nonsurgical resuscitation on admission), managed at Intensive Care Unit-Hospital das Clínicas - Universidade Estadual de Campinas were prospectively analysed. All patients were assessed by CT scan and 72 required neurosurgical intervention. All patients were continuously monitored to evaluate intracranial pressure (ICP) levels by a subarachnoid device (11 with subarachnoid metallic bolts and 195 with subarachnoid polyvinyl catheters). The ICP levels were continuously observed in the bedside pressure monitor display and their end-hour values were recorded in a standard chart. The patients were managed according to a standard protocol guided by the ICP levels. There were no intracranial haemorrhagic complications or hematomas due the monitoring method. Sixty six patients were punctured by lateral C1-C2 technique to assess infectious complications and 2 had positive cerebrospinal fluid samples for Acinetobacter sp. The final results measured at hospital discharge showed 75 deaths (36,40%) and 131 (63,60%) survivors. ICP levels had significantly influenced the final results (p<0,001). The subarachnoid method to continuously assess the ICP levels was considered aplicable, safe, simple, low cost and useful to advise the management of the patients. The ICP record methodology was practical and useful. Despite the current technical advances the subarachnoid method was considered viable to assess the ICP levels in severe head injury
