Exhibits

The Finnish American Heritage Center at Finlandia University recently installed three exhibits. They include a photographic exhibit titled “Rural Reflections: Finnish American Buildings and Landscapes in Michigan’s Copper Country”; a historic photography exhibit named “People, Place and Time: Michigan’s Copper Country Through the Lens of J.W. Nara”; and a pair of lithographs acquired by the National Park Service which were on either side of the Italian Hall stage the night of the infamous Christmas Eve tragedy 100 years ago. The “Rural Reflections” exhibit documents the built environment that Finnish immigrants and their descendants created in Michigan's Copper Country from the 1880s through the 1930s. Although much of this heritage has been lost with the passage of time, the district yet holds one of the largest concentrations of rural Finnish buildings and cultural landscapes in North America. The Nara exhibit, funded in part by descendants Robert and Ruth Nara of Bootjack Michigan, works from historical photographs held at the Michigan Tech Archives. Interpretive panels highlight the people, places, and times that J.W. Nara experienced during his lifetime and include material on urban life, farming, and the 1913 Michigan copper miners’ strike. The lithographs are a recent and unique acquisition for the Keweenaw National Historical Park, and will be on protected display at the FAHC. One of the panels shows the Italian royal family and was produced in 1908, while the other, produced in 1905, is of the five founders of the modern Italian state.

Ultrasound-guided paravertebral puncture and placement of catheters in human cadavers: an imaging study

BACKGROUND: During paravertebral block, the anterolateral limit of the paravertebral space, which consists of the pleura, should preferably not be perforated. Also it is possible that, during the block, the constant superior costotransverse ligament can be missed in the loss-of-resistance technique. We therefore aimed to develop a new technique for an ultrasound-guided puncture of the paravertebral space. METHODS: We performed 20 punctures and catheter placements in 10 human cadavers. A sonographic view showing the pleura and the superior costotransverse ligament was obtained with a slightly oblique scan using a curved array transducer. After inline approach, injection of 10 ml normal saline confirmed the correct position of the needle tip, distended the space, and enabled catheter insertion. The spread of contrast dye injected through the catheters was assessed by CT scans. RESULTS: The superior costotransverse ligament and the paravertebral space were easy to identify. The needle tip reached the paravertebral space without problems under visualization. In contrast, the introduction of the catheter was difficult. The CT scan revealed a correct paravertebral spread of contrast in 11 cases. Out of the remaining, one catheter was found in the pleural space, in six cases there was an epidural, and in two cases there was a prevertebral spread of contrast dye. CONCLUSIONS: We successfully developed a technique for an accurate ultrasound-guided puncture of the paravertebral space. We also showed that when a catheter is introduced through the needle with the tip lying in the paravertebral space, there is a high probability of catheter misplacement into the epidural, mediastinal, or pleural spaces.

Perforation of the median nerve with an acupuncture needle guided by ultrasound

In an experiment on one of the authors, we used ultrasound to visualise an acupuncture needle completely perforating the median nerve at the acupuncture point PC6. During this procedure only a slight sensation occurred, and no pain. We conclude that, in individual cases, the median nerve might be perforated without causing pain or neurological problems.

[Swiss Research Agenda for Nursing (SRAN): the development of an agenda for clinical nursing research in Switzerland]

In many Anglo-Saxon and North European countries nursing research agendas have been developed to address priorities in nursing research in accordance with a nationally defined health policy. In Switzerland, due to lack of a nationwide governmental health policy, co-ordination of nursing research so far was scarce. The "Swiss Research Agenda for Nursing (SRAN)" project developed an agenda for clinical nursing research between 2005 and 2007. Based on literature reviews, expert panels and a national survey a project team formulated an agenda which passed a consensus conference. The agenda recommends aspects that should lead research and defines seven research priorities for nursing in Switzerland for the time between 2007 and 2017. Nursing research should prioritize to investigate 1) the effectiveness of nursing interventions; 2) the influences of service adaptations in a changing health care system; 3) the phenomena in patients requiring nursing care; 4) the influence of the work environment on the quality of nursing care; 5) the functioning of family and social systems; 6) varieties of life circumstances and their integration; and 7) the implementation of ethical principles in nursing. Written in German and French, the Swiss Research Agenda for Nursing for the first time formulates priorities for nursing research in Switzerland and can be used for strategic discussions. As a next step, the development of an action plan to enhance nursing research will take place in Switzerland.

Injuring potential of drinking glasses

At a party of a sports club, an argument started between two groups of young men, in the course of which one of the persons involved threw a beer glass hitting a young man of the other group, who collapsed with a profusely bleeding wound. Although resuscitation measures were initiated immediately, the victim died at the scene due to exsanguination from the completely severed left external carotid artery in combination with the aspiration of blood. Tests with drinking glasses thrown at a skull-neck model suggested that an undamaged beer glass thrown at the head of the victim could not cause the fatal injuries on the neck because of its splintering behaviour. In fact, it seemed that the beer glass had been damaged prior to throwing it and that its sharp edges perforated the skin on hitting the neck.

Sustainability study of nanomaterials including societal and occupational implications

In recent years there has been a tremendous amount of research in the area of nanotechnology. History tells us that the commercialization of technologies will always be accompanied by both positive and negative effects for society and the environment. Products containing nanomaterials are already available in the market, and yet there is still not much information regarding the potential negative effects that these products may cause. The work presented in this dissertation describes a holistic approach to address different dimensions of nanotechnology sustainability. Life cycle analysis (LCA) was used to study the potential usage of polyethylene filled with nanomaterials to manufacture automobile body panels. Results showed that the nanocomposite does not provide an environmental benefit over traditional steel panels. A new methodology based on design of experiments (DOE) techniques, coupled with LCA, was implemented to investigate the impact of inventory uncertainties. Results showed that data variability does not have a significant effect on the prediction of the environmental impacts. Material profiles for input materials did have a highly significant effect on the overall impact. Energy consumption and material characterization were identified as two mainstreams where additional research is needed in order to predict the overall impact of nanomaterials more effectively. A study was undertaken to gain insights into the behavior of small particles in contact with a surface exposed to air flow to determine particle lift-off from the surface. A mapping strategy was implemented that allows for the identification of conditions for particle liftoff based on particle size and separation distance from the wall. Main results showed that particles smaller than 0:1mm will not become airborne under shear flow unless the separation distance is greater than 15 nm. Results may be used to minimize exposure to airborne materials. Societal implications that may occur in the workplace were researched. This research task explored different topics including health, ethics, and worker perception with the aim of identifying the base knowledge available in the literature. Recommendations are given for different scenarios to describe how workers and employers could minimize the unwanted effects of nanotechnology production.

Analysis of independent microarray datasets of renal biopsies identifies a robust transcript signature of acute allograft rejection

Transcriptomics could contribute significantly to the early and specific diagnosis of rejection episodes by defining 'molecular Banff' signatures. Recently, the description of pathogenesis-based transcript sets offered a new opportunity for objective and quantitative diagnosis. Generating high-quality transcript panels is thus critical to define high-performance diagnostic classifier. In this study, a comparative analysis was performed across four different microarray datasets of heterogeneous sample collections from two published clinical datasets and two own datasets including biopsies for clinical indication, and samples from nonhuman primates. We characterized a common transcriptional profile of 70 genes, defined as acute rejection transcript set (ARTS). ARTS expression is significantly up-regulated in all AR samples as compared with stable allografts or healthy kidneys, and strongly correlates with the severity of Banff AR types. Similarly, ARTS were tested as a classifier in a large collection of 143 independent biopsies recently published by the University of Alberta. Results demonstrate that the 'in silico' approach applied in this study is able to identify a robust and reliable molecular signature for AR, supporting a specific and sensitive molecular diagnostic approach for renal transplant monitoring.

Strategies to advance translational research into brain barriers

There is a paucity of therapies for most neurological disorders--from rare lysosomal storage diseases to major public health concerns such as stroke and Alzheimer's disease. Advances in the targeting of drugs to the CNS are essential for the future success of neurotherapeutics; however, the delivery of many potentially therapeutic and diagnostic compounds to specific areas of the brain is restricted by the blood-brain barrier, the blood-CSF barrier, or other specialised CNS barriers. These brain barriers are now recognised as a major obstacle to the treatment of most brain disorders. The challenge to deliver therapies to the CNS is formidable, and the solution will require concerted international efforts among academia, government, and industry. At a recent meeting of expert panels, essential and high-priority recommendations to propel brain barrier research forward in six topical areas were developed and these recommendations are presented here.

Surgical glove perforation and the risk of surgical site infection

HYPOTHESIS: Clinically apparent surgical glove perforation increases the risk of surgical site infection (SSI). DESIGN: Prospective observational cohort study. SETTING: University Hospital Basel, with an average of 28,000 surgical interventions per year. PARTICIPANTS: Consecutive series of 4147 surgical procedures performed in the Visceral Surgery, Vascular Surgery, and Traumatology divisions of the Department of General Surgery. MAIN OUTCOME MEASURES: The outcome of interest was SSI occurrence as assessed pursuant to the Centers of Disease Control and Prevention standards. The primary predictor variable was compromised asepsis due to glove perforation. RESULTS: The overall SSI rate was 4.5% (188 of 4147 procedures). Univariate logistic regression analysis showed a higher likelihood of SSI in procedures in which gloves were perforated compared with interventions with maintained asepsis (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.4-2.8; P < .001). However, multivariate logistic regression analyses showed that the increase in SSI risk with perforated gloves was different for procedures with vs those without surgical antimicrobial prophylaxis (test for effect modification, P = .005). Without antimicrobial prophylaxis, glove perforation entailed significantly higher odds of SSI compared with the reference group with no breach of asepsis (adjusted OR, 4.2; 95% CI, 1.7-10.8; P = .003). On the contrary, when surgical antimicrobial prophylaxis was applied, the likelihood of SSI was not significantly higher for operations in which gloves were punctured (adjusted OR, 1.3; 95% CI, 0.9-1.9; P = .26). CONCLUSION: Without surgical antimicrobial prophylaxis, glove perforation increases the risk of SSI.

Einbeziehung der privaten Krankenvollversicherung in den Risikostrukturausgleich der gesetzlichen Krankenversicherung in Deutschland. Abschätzung der quantitativen Auswirkungen

Die Einbeziehung der privaten Krankenversicherung (PKV) in den Risikostrukturausgleich (RSA) der gesetzlichen Krankenversicherung (GKV) wird häufig diskutiert. In der vorliegenden Studie wird anhand einer quantitativen Analyse unter Verwendung der Daten des Sozioökonomischen Panels (SOEP) abgeschätzt, welche Transfersumme aus dem System der PKV in das System der GKV fließen würden, wenn ein übergreifender RSA eingerichtet würde. Die Summe läge bei 9,9 Mrd. Euro pro Jahr unter Annahme der Beitragsbemessungsgrenze des Jahres 2006. Einbezogen wurden dabei nur die Unterschiede auf der Einnahmenseite des RSA. Einschränkend muss gesehen werden, dass unklar bleibt, welche Krankenversicherungsunternehmen be- oder entlastet würden und über welches Verfahren die Transfersumme aufgebracht werden könnte.

Plurilingual Interpretation in WTO Panel and Appellate Body Reports

This article analyzes the extent to which the Appellate Body and WTO panels compare the authentic texts in their examination of the WTO Agreements and the extent to which the parties themselves do so in their arguments. The texts of the WTO Agreements are authentic in English, French and Spanish. Article 33 of the Vienna Convention on the Law of Treaties governs the interpretation of treaties authenticated in two or more languages. WTO practice diverges significantly from the rules set out in Article 33 and the travaux préparatoires of the International Law Commission. The terms of a plurilingual treaty are presumed to have the same meaning in each authentic text, which means that a treaty interpreter need not compare the authentic texts as a routine matter as a matter of law. Nevertheless, routine comparison of authentic texts would be good practice in the WTO context, since there are several discrepancies that could affect the interpretation of WTO provisions.

In vitro temperature evaluation during cement augmentation of proximal humerus plate screw tips

BACKGROUND The treatment of proximal humerus fractures in patients with poor bone quality remains a challenge in trauma surgery. Augmentation with polymethylmethacrylate (PMMA) cement is a possible method to strengthen the implant anchorage in osteoporotic bone and to avoid loss of reduction and reduce the cut-out risk. The polymerisation of PMMA during cement setting leads, however, to an exothermic reaction and the development of supraphysiological temperatures may harm the bone and cartilage. This study addresses the issue of heat development during augmentation of subchondrally placed proximal humerus plate screws with PMMA and the possible risk of bone and cartilage necrosis and apoptosis. METHODS Seven fresh frozen humeri from geriatric female donors were instrumented with the proximal humerus interlocking system (PHILOS) plate and placed in a 37°C water bath. Thereafter, four proximal perforated screws were augmented with 0.5 ml PMMA each. During augmentation, the temperatures in the subchondral bone and on the articular surface were recorded with K-type thermocouples. The measured temperatures were compared to threshold values for necrosis and apoptosis of bone and cartilage reported in the literature. RESULTS The heat development was highest around the augmented tips of the perforated screws and diminished with growing distance from the cement cloud. The highest temperature recorded in the subchondral bone reached 43.5°C and the longest exposure time above 42°C was 86s. The highest temperature measured on the articular surface amounted to 38.6°C and the longest exposure time above 38°C was 5 min and 32s. CONCLUSION The study shows that augmentation of the proximal screws of the PHILOS plate with PMMA leads to a locally limited development of supraphysiological temperatures in the cement cloud and closely around it. The critical threshold values for necrosis and apoptosis of cartilage and subchondral bone reported in the literature, however, are not reached. In order to avoid cement extravasation, special care should be taken in detecting perforations or intra-articular cracks in the humeral head.

La philanthropie: alliée ou concurrente des politiques sociales étatiques (I, 1880-1945)

La philanthropie joue actuellement un rôle très important en Suisse. On estime que la moitié des personnes domiciliées en Suisse est active dans le champ d’action du bénévolat. Toutefois, cet objet d’études a longtemps été délaissé par les historiens. Ces deux panels viseront à rendre compte des recherches récentes en s’intéressant à la dimension comparative et transnationale de la philanthropie en Suisse de 1880 à nos jours. Deux dimensions seront privilégiées. D’une part, l’accent sera mis sur les rapports entre les associations philanthropiques privées et l’Etat social. Les études tendent le plus souvent à mettre l’accent sur l’opposition, dans le domaine social, entre activités de bienfaisance ou de bénévolat et les politiques publiques. Or, les relations entre ces deux pôles ne se résument pas à cette opposition et oscillent, selon les lieux et les périodes, entre coopération étroite et concurrence acharnée, à moins que ne s’instaure, comme cela semble le cas de la Suisse, une division du travail plus ou moins institutionnalisée. D’autre part, une attention toute particulière sera mise sur les jeux d’échelle. Les activités des associations philanthropiques couvrent des espaces géographiques très différents : certaines se concentrent sur un quartier urbain, d’autres se focalisent sur l’ensemble de la planète. Toutefois, nous postulons que cette spatialisation ne se confine pas à un antagonisme local/global. Bien au contraire, les différentes échelles – locale, nationale, globale ou transnationale – interagissent étroitement. Des contributions d’historiens étrangers permettront d’inscrire le cas suisse dans une perspective comparative.
