Epidemiology of pulmonary hypertension: new data from the Swiss registry.

since 1999 data from pulmonary hypertension (PH) patients from all PH centres in Switzerland were prospectively collected. We analyse the epidemiological aspects of these data. PH was defined as a mean pulmonary artery pressure of >25 mm Hg at rest or >30 mm Hg during exercise. Patients with pulmonary arterial hypertension (PAH), PH associated with lung diseases, PH due to chronic thrombotic and/or embolic disease (CTEPH), or PH due to miscellaneous disorders were registered. Data from adult patients included between January 1999 and December 2004 were analysed. 250 patients were registered (age 58 +/- 16 years, 104 (41%) males). 152 patients (61%) had PAH, 73 (29%) had CTEPH and 18 (7%) had PH associated with lung disease. Patients <50 years (32%) were more likely to have PAH than patients >50 years (76% vs. 53%, p <0.005). Twenty-four patients (10%) were lost to followup, 58 patients (26%) died and 150 (66%) survived without transplantation or thrombendarterectomy. Survivors differed from patients who died in the baseline six-minute walking distance (400 m [300-459] vs. 273 m [174-415]), the functional impairment (NYHA class III/IV 86% vs. 98%), mixed venous saturation (63% [57-68] vs. 56% [50-61]) and right atrial pressure (7 mm Hg [4-11] vs. 11 mm Hg [4-18]). PH is a disease affecting adults of all ages. The management of these patients in specialised centres guarantees a high quality of care. Analysis of the registry data could be an instrument for quality control and might help identify weak points in assessment and treatment of these patients.

Integration of high-resolution geophysical data for the characterization of alluvial aquifers : new approaches and implications for hydrological predictions

Abstract Accurate characterization of the spatial distribution of hydrological properties in heterogeneous aquifers at a range of scales is a key prerequisite for reliable modeling of subsurface contaminant transport, and is essential for designing effective and cost-efficient groundwater management and remediation strategies. To this end, high-resolution geophysical methods have shown significant potential to bridge a critical gap in subsurface resolution and coverage between traditional hydrological measurement techniques such as borehole log/core analyses and tracer or pumping tests. An important and still largely unresolved issue, however, is how to best quantitatively integrate geophysical data into a characterization study in order to estimate the spatial distribution of one or more pertinent hydrological parameters, thus improving hydrological predictions. Recognizing the importance of this issue, the aim of the research presented in this thesis was to first develop a strategy for the assimilation of several types of hydrogeophysical data having varying degrees of resolution, subsurface coverage, and sensitivity to the hydrologic parameter of interest. In this regard a novel simulated annealing (SA)-based conditional simulation approach was developed and then tested in its ability to generate realizations of porosity given crosshole ground-penetrating radar (GPR) and neutron porosity log data. This was done successfully for both synthetic and field data sets. A subsequent issue that needed to be addressed involved assessing the potential benefits and implications of the resulting porosity realizations in terms of groundwater flow and contaminant transport. This was investigated synthetically assuming first that the relationship between porosity and hydraulic conductivity was well-defined. Then, the relationship was itself investigated in the context of a calibration procedure using hypothetical tracer test data. Essentially, the relationship best predicting the observed tracer test measurements was determined given the geophysically derived porosity structure. Both of these investigations showed that the SA-based approach, in general, allows much more reliable hydrological predictions than other more elementary techniques considered. Further, the developed calibration procedure was seen to be very effective, even at the scale of tomographic resolution, for predictions of transport. This also held true at locations within the aquifer where only geophysical data were available. This is significant because the acquisition of hydrological tracer test measurements is clearly more complicated and expensive than the acquisition of geophysical measurements. Although the above methodologies were tested using porosity logs and GPR data, the findings are expected to remain valid for a large number of pertinent combinations of geophysical and borehole log data of comparable resolution and sensitivity to the hydrological target parameter. Moreover, the obtained results allow us to have confidence for future developments in integration methodologies for geophysical and hydrological data to improve the 3-D estimation of hydrological properties.

Contribution to the geology of Southern Turkey: new insights from the Mersin mélanges and from the Lycian and Antalya nappes

Abstract The study of fossil Tethyan continental margins implies the consideration of the oceanic domains to which they were connected. The advent of plate tectonics confirmed the importance of the detection of accretion-related mélanges. Ophiolitic mélanges are derived from both an upper ophiolitic obducting plate and a lower oceanic plate. Besides ophiolitic elements, the mélanges may incorporate parts of a magmatic arc and dismembered fragments of a passive continental margin. As the lower plate usually totally disappears during the obduction process, it can only be reconstructed from its elements found in the mélanges. Because of their key location at active margin boundaries, preserved accretion-related mélanges provide strong constraints on the geological evolution of former oceanic domains and their adjacent margins. The identification of Palaeotethyan remnants as accretionary series or reworked during the Late Triassic Eo-Cimmerian event, as well as the recognition of HugluPindos marginal sequences in southern Turkey and in the external Hellenides represent the main achievements of this work, making possible to establish new palaeogeographical correlations. The Mersin mélanges (Turkey), together with the Antalya and Mamonia (Cyprus) domains, are characterized by a series of exotic units found now south of the main Taurus range and compose the South-Taurides Exotic Units. The Mersin mélanges are subdivided in a Triassic and a Late Cretaceous unit. These units consist of the remnants of three major Tethyan oceans, the Palaeotethys, the Neotethys and the Huglu-Pindos. The definition and inventory of the Upper Antalya Nappes (Turkey) are still a matter of controversies and often conflicting interpretations. The recognition of Campanian radiolarians on top of the Kerner Gorge unit directly overlain by the Ordovician Seydi§ehir Fm. of the Tahtah Dag Nappe outlines a tectonic contact and demonstrates that the Upper Antalya Nappes system is composed of three different nappes, the Kerner Gorge, Bakirli and the Tahtah Dag nappes. Additionally, a limestone block in a doubtful tectonic position at the base of the Upper Antalya Nappes yielded for the first time two middle Viséan associations of foraminifers and problematic algae. The Tavas Nappe in the Lycian Nappes (Turkey) is classically divided into the Karadag, Teke Dere, Köycegiz and Haticeana units. As for the Mersin mélanges, the Tavas Nappe is highly composite and includes dismembered units belonging to the Palaeotethyan, Neotethyan and HugluPindos realms. The Karadag unit consists of a Gondwana-type platform succession ranging from the Late Devonian to the Late Triassic. It belongs to the Cimmerian Taurus terrane and was part of the northern passive margin of the Neotethys. The Teke Dere unit is composed of different parts of the Palaeotethyan succession including Late Carboniferous OIB-type basalts, Carboniferous MORB-type basalts, an Early Carboniferous siliciclastic series and a Middle Permian arc sequence. The microfauna and microflora identified in different horizons within the Teke Dere unit share strong biogeographical affinities with the northern Palaeotethyan borders. Kubergandian limestones in primary contact above the Early Carboniferous siliciclastics yielded a rich and diverse microfauna and microflora also identified in reworked cobbles within the Late Triassic Gevne Fm. of the Aladag unit (Turkey). The sedimentological evolution of the Köycegiz and Haticeana series is in many points similar to classical Pindos sequences. These series originated in the Huglu-Pindos Ocean along the northern passive margin of the Anatolian (Turkish transect) and Sitia-Pindos (Greek transect) terranes. Conglomerates at the base of the Lentas Unit in southern Crete (Greece) yielded a microfauna and microflora presenting also strong affinities with the northern borders of the Palaeotethys. This type of reworked sediments at the base of Pindos-like series would suggest a derivation from the Palaeotethyan active margin. -Résumé (French abstract) L'étude des marges continentales fossiles de l'espace téthysien implique d'étudier les domaines océaniques qui y étaient rattachés. Les progrès de la tectonique des plaques ont confirmé l'importance de la reconnaissance des mélanges d'accrétion. Les mélanges ophiolitiques dérivent d'une plaque supérieure ophiolitique qui obducte, et d'une plaque inférieure océanique. En plus d'éléments ophiolitiques, les mélanges peuvent aussi incorporer des parties d'un arc magmatique, ou des fragments d'une marge continentale passive. Comme la plaque inférieure disparaît généralement complètement durant le processus d'obduction, elle ne peut être reconstruite qu'au travers de ses éléments trouvés dans les mélanges. A cause de leur situation aux limites de marges actives, les mélanges d'accrétion bien préservés permettent de contraindre l'évolution géologique d'anciens océans et de leurs marges. L'identification de vestiges de la Paléotéthys en série d'accrétion ou remaniés lors de l'orogenèse éo-cimmérienne au Trias supérieur, ainsi que l'observation de séquences marginales de Huglu-Pinde en Turquie du sud et dans les Hellénides externes représentent les principaux résultats de ce travail, permettant d'établir de nouvelles corrélations paléogéographiques. Les mélanges de Mersin (Turquie), avec les domaines d'Antalya et de Mamonia (Chypre), sont caractérisés par des unités exotiques se trouvant au sud de la chaîne taurique, et forment les Unités Exotiques Sud-Tauriques. Les mélanges de Mersin sont subdivisés en une unité triasique, et une autre du Crétacé supérieur. Ces unités comprennent les reliques de trois principaux océans téthysiens, la Paléotéthys, la Néotéthys et Huglu-Pinde. L'inventaire et la définition des nappes supérieures d'Antalya (Turquie) sont encore matière à controverse et donne lieu à des interprétations conflictuelles. La découverte de radiolaires campaniens au sommet de l'unité de la Gorge de Kemer, directement recouverts par la formation ordovicienne de Seydisehir de la nappe du Tahtali Dag met en évidence un contact tectonique et démontre que les nappes supérieures sont composées de trois différentes nappes, celle de la Gorge de Kemer, celle du Bakirli et celle Tahtali Dag. De plus, un bloc de calcaire dont la position tectonique demeure incertaine à la base des nappes supérieures a fourni pour la première fois deux associations viséennes de foraminifères et d'algues problématiques. La nappe de Tavas dans les nappes lyciennes (Turquie) est séparée en unités du Karadag, du Teke Dere, de Köycegiz et d'Haticeana. Comme pour les mélanges de Mersin, la nappe de Tavas est composite et inclut des unités appartenant à la Paléotéthys, à la Néotéthys et à Huglu-Pinde. L'unité du Karadag est une plateforme carbonatée de type Gondwana se développant du Dévonien supérieur au Trias supérieur. Elle appartient au domaine cimmérien du Taurus et formait la marge nord de la Néotéthys. L'unité du Teke Dere est composée de différentes écailles paléotéthysiennes et inclut des basaltes d'île océanique du Carbonifère supérieur, des basaltes de ride océanique du Carbonifère, une série siliciclastique du Carbonifère supérieur et un arc du Permien moyen. Les microfaunes et -flores trouvées à différents niveaux de la série du Teke Dere partagent de fortes affinités paléogéographiques avec les marges nord de la Paléotéthys. Des calcaires du Kubergandien en contact primaire au-dessus de la série siliciclastique a donné de riches microfaunes et -flores, également identifiées dans des galets remaniés dans la formation de Gevne du Trias supérieur de l'Aladag. L'évolution sédimentologique des séries de Köycegiz et d'Haticeana sont très similaires aux séries classiques du Pinde. Ces séquences prennent leur racine dans l'océan de Huglu-Pinde, le long de la marge passive nord anatolienne (profil turc) et de la marge de Sitia-Pinde (profil grec). Des conglomérats à la base de l'unité de Lentas au sud de la Crète (Grèce) ont donné des microfaunes et flores partageant également de fortes similitudes avec les bordures nord de la Paléotéthys. Le type de sédiments remaniés à la base d'unités de type Pinde suggère une dérivation depuis la marge active de la Paléotéthys. -Résumé grand public (non-specialized abstract) Au début du 20ème siècle, Alfred Wegener bouleverse les croyances géologiques de l'époque et publie plusieurs articles sur la dérive ou la translation des continents. En utilisant des arguments géographiques (similarités des lignes de côte), paléontologiques (faunes et flores similaires) et climatiques (dépôts tropicaux et glaciaires), Wegener explique qu'il y a plusieurs millions d'années, les terres émergées actuelles ne devaient former qu'un seul et grand continent. La fin du 20ème siècle verra l'avènement de la théorie de la tectonique des plaques suite à la reconnaissance du cycle de Wilson, des rides médio-océaniques, des anomalies magnétiques dans les océans et des sutures océaniques qui représentent les reliques d'océans disparus. Le Cycle de Wilson se caractérise par une suite d'évènements géologiques majeurs pouvant se résumer de la manière suivante : (1) séparation d'un craton continental en deux parties, créant une limite de plaque divergente. C'est ce que l'on appelle un rift; (2) développement et croissance d'un océan entre ces deux blocs. Des roches magmatiques remontent à la surface de la terre et forment une chaîne de montagne sous-marine que l'on appelle ride médio-océanique ou dorsale. L'océan continue de se développer, et des sédiments se déposent à sa surface formant la suite ophiolitique ou trinité de Steinmann; (3) après une phase d'expansion plus ou moins longue, les conditions imposées aux limites des plaques à la surface de la terre changent, et l'océan se met à se refermer par disparition progressive (subduction) de sa croûte océanique sous une croûte continentale par exemple. Ceci crée une nouvelle limite de plaque, convergente cette fois; (4) la subduction de la plaque océanique sous la plaque continentale provoque une remontée de magma formant des chaînes volcaniques à la surface de la Terre ; (5) une fois que la plaque océanique a complètement disparu, les deux blocs préalablement séparés par l'océan font collision, formant ainsi une chaîne de montagne. Les chaînes de montagnes sont de manière générale formées par un empilement plus ou moins complexe de nappes. C'est au coeur de certaines de ces nappes que se trouvent les vestiges de l'océan disparu. Un des objectifs de ce travail était la recherche de ces vestiges dans le domaine téthysien de la Méditerranée orientale. Pour ce faire, nous avons parcourus une grande partie du sud de la Turquie, nous sommes allés à Chypre, dans le Sultanat d'Oman, en Iran, en Crète, et nous avons visités quelques îles grecques du Dodécanèse. La région de la Méditerranée orientale est une zone qui a été tectoniquement très active, et qui continue de l'être de nos jours par des phénomènes de subduction (ex. les volcans de Santorin), et par des mouvements coulissants entre des plaques continentales (ex. la faille nord-anatolienne) qui donnent régulièrement lieu à des tremblements de terre. Pour le géologue, la complexité de ces zones d'étude réside dans le fait que les chaînes de montagne actuelles ne contiennent en général pas seulement les restes d'un océan, mais bien de plusieurs bassins océaniques qui se sont succédés dans l'espace et dans le temps. Les nappes qui se trouvent au sud de la Turquie et dans le Dodécanèse forment un important jalon dans la chaîne alpine qui s'étend depuis les Alpes jusque dans l'Himalaya. L'idée d'un continuum au coeur de ce système se basait principalement sur l'âge des océans et sur la reconnaissance de similarités dans l'évolution des séries sédimentaires. La localisation des vestiges de la Paléotéthys ainsi que l'identification des séries sédimentaires ayant appartenu à l'océan de HugluPinde repris sous forme de nappes en Turquie et en Grèce sont cruciales pour permettre de bonnes corrélations locales et régionales. La reconnaissance, la compréhension et l'interprétation de ces séries sédimentaires permettront d'élaborer un modèle d'évolution géodynamique régional, s'appuyant sur des faits de terrains indiscutables, et prenant en compte les contraintes globales que ce genre d'exercice implique.

Frequency and determinants of using pharmacological enhancement in the clinical practice of in-hospital stroke rehabilitation.

Background: Pharmacological enhancement in stroke rehabilitation (PESR) is promising. Data about its use in clinical practice are missing. Methods: In a prospective, explorative study of four rehabilitation centers, we systematically observed the frequency and determinants of using PESR in consecutive patients. PESR was defined as using agents potentially enhancing post-stroke recovery exclusively to aid rehabilitation without an established indication. Results: 257 (55.4%) of 464 patients had agents potentially enhancing recovery. Selective serotonin reuptake inhibitors (SSRI) (n = 125, 26.9%), levodopa (n = 114, 24.6%), serotonin-noradrenaline reuptake inhibitors (SNRI) (n = 52, 11.2%), and acetylcholinesterase inhibitors (n = 48, 10.3%) were used most often. SSRI in 102/125 patients and SNRI in 46/52 patients were mostly used for accompanying depressive symptoms. 159 (34.3%) patients had PESR (without an otherwise established indication). In PESR patients, levodopa (n = 102, 64.1%) was used most commonly. PESR was primarily used for aphasia (36.5%) and paresis (25.2%). PESR patients did not differ from non-PESR patients in age, gender and stroke type. However, the utilization rates of PESR differed significantly across centers (2, 4, 38 and 55%). Conclusion: SSRI and SNRI were predominately used for accompanying depression, while levodopa was nearly exclusively used to aid stroke rehabilitation in the absence of an otherwise established indication. The differences in utilization rates for PESR between centers suggest therapeutic uncertainty and indicate the need for additional studies.

Pieces of Iowa’s Past, March 21, 2012

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. March 21, 2012 THIS WEEK: Quick Work at Carlisle(From the Indianola Tribune, December 20, 1877) BACKGROUND: Lewis Todhunter was born in Fayette County, Ohio, April 6, 1817. He was admitted to the bar in Highland County, Ohio, in 1848. Todhunter came to Iowa in 1850, settling along the Des Moines River in Polk County, where he was engaged in farming and selling goods. In 1854, he moved to Indianola and began the practice of law, continuing in that profession for more than a quarter of a century. He served as prosecuting attorney, county auditor, treasurer, and mayor of the city. He was a member of the third constitutional convention, which met at Iowa City in 1857, representing Warren, Madison, Adair, and Cass counties in that body and had the honor of assisting in making the first laws of the state. Todhunter served in the army during the Civil War from 1863-1865 as assistant quartermaster with rank of Captain. He is perhaps widest known, however, as a temperance leader and earnest worker. He joined in the Washingtonian movement in 1840 and was active in temperance reformation for the rest of his life.

Comparison of the site distribution of melanoma in New Zealand and Canada

A comparison of the site distribution of cutaneous malignant melanoma in New Zealand and Canada was performed. This series deals with 41,331 incident cases registered between 1968 and 1990 and is the largest to date to evaluate the influence of age and gender on the site distribution of melanoma. Site-specific, age-standardized rates per unit surface area and relative tumour density were assessed by gender and country and differences compared with statistical techniques adapted to this context. The age-standardized rates for all sites were higher in New Zealand than in Canada, the ratio being 3.2 for men and 3.8 for women. Occurrence of melanoma was denser for chronically than intermittently exposed sites in both New Zealand and Canada. The highest incidence rate per unit area was for the ears in men which was more than 5 times the rate for the entire body in each country. For each gender, melanomas were relatively commoner on the trunk and the face in Canada, and on the lower limbs in New Zealand. The variations in the site distribution were similar in each country and consistent with the effect of differential patterns of sun exposure between genders. Our results show that the levels of risk of melanoma between phenotypically comparable populations exposed to different amount of UV radiation vary in a site-specific manner, especially for intermittently exposed sites. This suggests that both environmental conditions and lifestyle factors influence the site distribution of melanoma in these two populations.

A recent inventory of the bats of Mozambique with new documentation of 7 new species for the country

The bat fauna of Mozambique is poorly documented. We conducted a series of inventories across the country between 2005 and 2009, resulting in the identification of 50 species from 41 sites. Of these, seven species represent new national records that increase the country total to 67 species. These data include results from the first detailed surveys across northern Mozambique, over an area representing almost 50% of the country. We detail information on new distribution records and measurements of these specimens. Special attention is paid to the Rhinolophidae, because these include several taxa that are currently in a state of taxonomic confusion. Furthermore, we also present some notes on taxonomy, ecology and echolocation calls. Finally, we combine modelled distributions to present predicted species richness across the country. Species richness was lowest across the coastal plain, to the east and far north, and is predicted to increase in association with rising altitude and higher topographic unevenness of the landscape.

A composite stratigraphy for the Neoproterozoic Huqf Supergroup of Oman: integrating new litho-, chemo- and chronostratigraphic data of the Mirbat area, southern Oman

The Huqf Supergroup in Oman contains an exceptionally well-preserved and complete sedimentary record of the Middle to Late Neoproterozoic Era. Outcrops of the Huqf Supergroup in northern and central Oman are now well documented, but their correlation with a key succession in the Mirbat area of southern Oman, containing a sedimentary record of two Neoproterozoic glaciations, is poorly understood. Integration of lithostratigraphic, chemostratigraphic and new U-Pb detrital zircon data suggests that the Mirbat Group is best placed within the Cryogenian (c. 850-635 Ma) part of the Huqf Supergroup. The c. I km thick marine deposits of the Arkahawl and Marsham Formations of the Mirbat Group are thought to represent a stratigraphic interval between older Cryogenian and younger Cryogenian glaciations that is not preserved elsewhere in Oman. The bulk of detrital zircons in the Huqf Supergroup originate from Neoproterozoic parent rocks. However, older Mesoproterozoic, Palaeoproterozoic and even Archaean zircons can be recognized in the detrital population from the upper Mahara Group (Fiq Formation) and Nafun Group, suggesting the tapping of exotic sources, probably from the Arabian-Nubian Shield.
