Papierlos? Rechtlos! Die Gesundheitsversorgung von Menschen ohne legalen Aufenthaltsstatus
Authors: Sayed Mustapha , Schmidt-Semisch Henning 
Published: June 2015

Zusammenfassung:
Papierlose Menschen gehören in Deutschland zum Personenkreis, die nach dem Asylbewerberleistungsgesetz Anspruch auf eine medizinische Versorgung haben. Im Rahmen einer qualitativen Untersuchung wurden teilstandardisierte Experten- und Betroffeneninterviews in den Städten Hannover und Bremen durchgeführt. Die Betroffenen machen in den Interviews deutlich, dass sie faktisch rechtlos sind, da sie aus Angst vor Aufdeckung nur sehr selten die vorhandenen rechtlichen Ansprüche auf medizinische Versorgung wahrnehmen.

Published: June 2015

Zusammenfassung
Health Literacy zielt auf die Fähigkeiten gesundheitsbezogene Informationen zu beschaffen und damit umzugehen. Erste Studien deuten darauf hin, dass Migranten in ihrer Health Literacy deutlich schlechter abschneiden als die Vergleichsbevölkerung des Ziellandes. In Deutschland steht eine empirische Betrachtung der besonders gefährdeten Subpopulationen oder der risikoerhöhenden Konstellationen, aber auch der Konsequenzen und wirksamen Interventionsmöglichkeiten jedoch noch aus.

Published: June 2015

Abstract
An early diagnosis of bone metastases is very important for providing a profound decision on a subsequent therapy. In this study, a new
agent for SPECT-imaging of bone metastases,
111In-(4-{[(bis(phosphonomethyl))carbamoyl]methyl}-7,10-bis(carboxymethyl)-1,4,7,10-tetraazacyclododec-1-yl) acetic acid
(111In-BPAMD) complex has been developed with specific activity of 2.85 TBq/mmol. Radiochemical purity of the
radiolabeled complex was checked by instant thin layer chromatography method indicated high radiochemical purity > 95% at
the optimal conditions. The complex demonstrated significant stability at room temperature and in human serum at least for
48 h. Hydroxyapatite (HA) binding assay showed high binding ability of the radiolabeled complex even at the low amounts of
HA. Also, log P measurements highlighted the strong hydrophilic nature of the complex. Biodistribution studies as well as planar
imaging after injection of the complex into the male Syrian mice showed major accumulation of the labelled compound in the bone
tissue. Totally, the obtained results indicated that 111In-BPAMD has interesting characteristics as an agent for
SPECT-imaging of the bone metastases.
The Black Man’s Burden? – Language and Political Economy in a Diglossic State and Beyond
Authors: Farquharson Joseph T. 
Published: June 2015

AbstractThe article looks at language as capital, with particular reference to the Jamaican language, highlighting the parallels and interactions between the economic and linguistic systems. In the ongoing discourse on language in Jamaica, Jamaican Creole has generally been viewed as a problem. It is normally the first excuse offered for why many Jamaican children do poorly in English in high-stakes examinations, and is often seen as a hindrance to social and economic advancement both locally and internationally. By looking at the expansion of the language in several ‘new’ domains, and drawing on research in linguistics which deals with this expansion, the article argues that Jamaican has been undergoing a revaluation which has the potential to place economic power in the hands of its speakers. This project is important because the Jamaican language has normally been viewed as a burden for Black Jamaicans. The wordburdenin the title is being used not in the sense of an onerous task which one is obligated to do, but in the sense of a hindrance, something one should get rid of. The question mark signals that I wish to interrogate the perspective which labels the language as an obstacle for its speakers.
Transforming into a Swallow: Coffin Text Spell 294 and Avian Behaviour
Authors: Cooper Julien , Evans Linda 
Published: June 2015

Summary
Coffin Texts Spell 294 describes the transformation of the deceased into a mn.t-bird. Examination of the passage from a lexical, mythological, and geographical perspective have highlighted the bird’s solar and Hathoric associations, but additional layers of meaning are revealed when textual references are also examined zoologically. This approach has shown that Spell 294 accurately describes the appearance and natural behaviour of migratory and resident barn swallows (Hirundo rustica), elucidating formerly problematical allusions and leading to a deeper understanding of the spell’s transformative process.

Abstract
Cu2ZnSiSe4 belong to the adamantine family of quaternary chalcogenides crystallizing in the wurtzstannite structure. Recent ab-initio calculations show, that the lowest energy structure of Cu2ZnSiSe4 is the wurtzkesterite type structure in contrast to wurtzstannite type, usually obtained in experiments. To clarify this issue a structural study on single crystals of Cu2ZnSiSe4 was performed for the first time. The structural characterization of the single crystals was carried out by X-ray diffraction at two different temperatures – room temperature and 150 K. The XRD data analysis shows, that Cu2ZnSiSe4 single crystals adopt the orthorhombic wurtzstannite type structure (space group Pmn21) and lattice parameters a = 7.809 Å, b = 6.778 Å, c = 6.447 Å at 150 K, and lattice parameters a = 7.821 Å, b = 6.734 Å, c = 6.453 Å at room temperature were derived. The structural parameters were confirmed for the polycrystalline Cu2ZnSiSe4 bulk sample.

Published: June 2015

Background: A primary hepatic neuroendocrine tumour (PHNET) is a very rare disease. The liver represents the preferential site for neuroendocrine tumors' metastases.Case presentation: A 45-year old Caucasian female who presented with nausea, vomiting, diarrhea, accompanied by diffuse abdominal pain was found to have on contrast-enhanced computer tomography an encapsulated, partially cystic liver mass. The patient underwent an uneventful left atypical hepatic resection. Histopatological and immunohistochemical examination revealed a slowly growing (G1) hepatic neuroendocrine tumour. Post surgery, the specific neuroendocrine markers (serum Chromogranin A and 24h urinary 5 hydroxy-indolacetic acid) were within normal range. Further functional imaging investigations were performed. No other lesions were found making probable the diagnosis of PHNET. The patient is presently after 4 years of follow-up with no local recurrence or distant metastases.Conclusions: The diagnosis of PHNET is a medical challenge that requires a thorough longterm follow-up in order to exclude an occult primary neuroendocrine tumour.
Early Achievable Severity (EASY) Index for Simple and Accurate Expedite Risk Stratification in Acute Pancreatitis
Authors: Hritz István , Hegyi Péter 
Published: June 2015

Background: Acute pancreatitis (AP) is one of the most common diseases of the gastrointestinal tract associated with significant morbidity and mortality. The assessment of severity is crucial in the management of the disease. Current methods of risk stratification in AP have a limited value, as they provide little additional information thus delaying appropriate patient care. Early recognition of severe disease may prevent serious adverse events and improve patient management as well as overall clinical outcome.Methods/Design: The EASY trial is an observational, multicenter, prospective cohort study for establishing a simple, easy and accurate clinical scoring system for early prognostication of AP. Evaluation of simple attainable potential prognostic parameters obtained at admission (or not later than 6-12 hours afterwards) from patients diagnosed with AP will be performed to assess their potential correlation with the disease severity. The selected parameters that show the strongest correlation with severe disease course will be further utilized as potential early severity prognostic markers for prospective new patient stratification. Comparison of patients' clinical course with the obtained results of early risk stratification may validate the utilized parameters as prognostic markers. The trial has been (i) discussed and (ii) accepted in a distinguished international scientific meeting, (ii) receiving the relevant ethical approval (TÜKEB: 30595-1/2014/EKU), (ii) registered at the ISRCTN registry which is a primary clinical trial registry recognized by WHO (Trial registration number: ISRCTN10525246).Conclusion: The EASY trial is designed to develop a simple and accurate clinical scoring system that can stratify patients with AP during the first 6-12 hours of hospitalization according to their risk for severe disease course.Key words: - - - -.

Authors: Togănel Răzvan Dan , Şimon Ioan , Zolog Adriana , Simescu Răzvan , Cozma Angela , Muntean Valentin 
Published: June 2015

Background: Psammocarcinomas (PCas) are rare epithelial tumors, usually originating in the ovaries or the peritoneum. These tumors are morphologically characterized by extensive psammomatous calcifications, invasiveness and low-grade cytological features.Case report: We present the case of a 54-year-old woman who was referred to our department with an umbilical tumor and increasing abdominal girth. The patient had had an umbilical hernia for more than 20 years. The CA 125 level was normal. The CT scan showed small peritoneal nodules at the level of the Douglas pouch, including the posterior wall of the uterus, and the entire colon, as well as large nodules located on the caecum and the sigmoid colon. We performed partial enterectomy, total colectomy with ileo-rectal anastomosis, omentectomy, total histerectomy and bilateral adnexectomy, pelvic peritonectomy of the Douglas pouch. Pathology findings were consistent with F.I.G.O. stage IIIC peritoneal PCa. The patient received adjuvant chemotherapy with Taxol and Carboplatin. To date, twelve months after surgery, the follow-up shows no evidence of disease.Conclusion: Standardized treatment protocols are hindered by the rarity of the PCas. However, literature concludes that optimal debulking is mandatory, whereas the efficacy of adjuvant chemotherapy remains to be elucidated.
Coping Strategies and Irrational Beliefs as Mediators of the Health-Related Quality of Life Impairments in Irritable Bowel Syndrome
Authors: Fadgyas Stanculete Mihaela , Matu Silviu , Pojoga Cristina , Dumitrascu Dan L. 
Published: June 2015

Background & Aims: Irritable bowel syndrome (IBS) is a chronic and disabling gastrointestinal disorder. Although considerable research has underlined the influence of coping mechanisms as the determinants of the quality of life (QOL), only limited data are available regarding the specific coping mechanisms used by IBS patients to manage illness in daily life. Irrational cognitions are known to emerge in stressful situations such as chronic diseases, and it has been proposed to have implications in the QOL. The aim of this study was to explore the relationship between coping styles and irrational beliefs in predicting the effects of IBS symptoms on the health-related QOL (HRQOL).Methods: A cross-sectional study was performed at two tertiary gastroenterology centers. A sample of 70 consecutive IBS patients and 55 healthy controls was studied. All participants completed the Brief Cope Inventory, the Dysfunctional Attitudes Scale, the Short-Form Health Survey and a demographic questionnaire.Results: All the HRQOL scores of the group with IBS were significantly lower than the HRQOL scores of the healthy group [Pillai's trace V = 0.404, F(8, 116) = 9.833, p < 0.001]. Irritable bowel syndrome patients used more problem-focused coping and avoidant-oriented coping than healthy subjects. The impact of IBS symptoms on HRQOL distress is mediated by irrational beliefs and avoidant oriented coping.Conclusions: Our findings highlight the role of irrational cognition and coping mechanisms in patients with IBS. The results underline the importance of the evaluation of psychological aspects of IBS with the possibility of having more tailored treatments for these patients.

Evaluating the Risk of Casing Failure Caused by High-Density Perforation: A 3D Finite-Element-Method Study of Compaction-Induced Casing Deformation in a Deepwater Reservoir, Gulf of Mexico
Authors: Guo Y.. , Blanford M.. , Candella J. D. 
Published: June 2015

Summary
For a deviated well planned in a highly compressible deepwater reservoir in the Gulf of Mexico, a typical perforation strategy of 140° phasing with 16 shots/ft is unlikely to meet flux requirements at the anticipated production rate. Perforating the production casing twice to double the flow area is one option to avoid exceeding the maximum flux limit. But will the high-density perforations affect the casing strength enough to cause casing failure as the reservoir compacts, given the reservoir-operating limits? This cannot be assessed by using existing analytical models, by published numerical models, or from available empirical or experimental data.
To evaluate the feasibility of using a double-perforation approach, a 3D finite-element method (FEM) was developed to determine the effect of the additional holes on casing failure. The model considers variations in both casing thickness and perforation pattern during expected wellbore and reservoir conditions. Both perforated and nonperforated casings were analyzed to compare casing-deformation characteristics and to determine the effect of the perforation on critical depletion pressures.
The FEM model shows that casing deformation is not uniform, resulting from nonuniform strain loading across reservoir boundaries and nonuniform distribution of casing strength as a result of the perforation. For the nonperforated casing, the maximum strain is associated with bending near the reservoir boundaries. In contrast, the maximum distortion of the perforated casing is concentrated around the perforation holes at the ends of the perforated intervals. Allowing for a critical strain of 6% in the casing, the depletion limit would have to be reduced from 3,500 psi to 2,600 psi if the second set of perforations could be applied uniformly relative to the first set. A nonuniform distribution of the second set could further reduce the casing strength and lower the critical depletion pressure to 2,200 psi. Finally, the study also shows that increasing the casing thickness by 0.0625 in. would have almost no effect on casing deformation or the attendant reservoir-operating limit.
The study quantifies how much casing strain to expect in the scenario described—and that is critical for evaluating the risk of casing failure in expensive deepwater wells. The results suggest that models similar to the one described here, in fact, offer a feasible way to assess casing deformation in highly compressible reservoirs in which high-density perforation may lead to casing failure.
Overcoming Extended-Reach Challenges for Annular Fracturing
Authors: Castro L.. , Craig S.. , Micheli R.. , Livescu S.. 
Published: June 2015

Summary
More operators are seeing the production benefits of targeted, horizontal annular fracturing. The most-active method of annular fracturing in the US involves ported sleeves installed with the completion and activated by means of an isolation packer. Initial operations were in lateral lengths of 2,000 to 3,000 ft; however, current operations are planned for accessing lateral lengths up to 10,000 ft. Increasing lateral length results in the traditional access challenges faced by all coiled-tubing operations. The traditional method of lubricant use is the primary option because of its simplicity. The second method is to use fluid-hammer tools (FHTs). These are industry standard for improving efficiency in composite-plug milling operations, but their use in genuine extended-reach operations is not as broad.
This paper briefly covers historical ported-annular-fracturing operations and the various methods of achieving increased lateral reach. Results from four wells that have a lateral reach of 7,200 to 10,277 ft are detailed in the paper. The balance of the paper details operational results and optimization from several extended-reach wells.
Detailed lateral-reach modeling was performed before all operations. This permitted the determination of the number of expected stages that would require the use of lubricant in the fracture-treatment flush. Given that residual lubricant in the completion is removed by the erosion effects of the proppant in the fracture treatment, each stage would require an additional fluid flush. This gives an opportunity to modify the lubricant concentration, type, and volume in the flush. Before using FHTs for setting the isolation packer, laboratory testing was performed to ensure the bottomhole-assembly-system compatibility.
The lubricant testing and initial field results were reported previously (Livescu and Craig 2014; Livescu et al. 2014a, 2014b). This paper provides operators with sufficient case histories of the planned use of an advanced lubricant in genuine extended-reach wells in real-life situations. This knowledge can improve operator confidence in drilling longer laterals for predictable access for annular-fracturing operations.

Authors: Romelczyk B. , Kulczyk M. , Pakieła Z. 
Published: June 2015

The aim of this study was to characterize the microstructure and properties of fine-grained iron. The samples were prepared by sintering at 1000°C ±5°C for 30 minutes, followed by Severe Plastic Deformation via Hydrostatic Extrusion (HE). After the sintering the rod samples were capsulated to prevent damage during extrusion. HE has been applied as a final consolidation process of iron powders. The HE process was carried out on two extrusion passes. The rods of 8 mm in diameter were obtained as a final product after hydroextrusion. The total cumulative strain was 2.3. Materials in three states were investigated: sintered, sintered and deformed by one hydrostatic extrusion pass, and two hydrostatic extrusion passes. The results were compared with the results obtained for coarse-grained Armco iron. The measurements showed that the grain size was reduced from 3.5 μm after sintering to 180±81 nm after the 2nd extrusion pass. The tensile strength and microhardeness increased with cumulative strain of the material. The impact test carried out at -196°C showed transformation of the fracture mechanism from cleavage for coarse-grained structure to ductile for extruded material.

Deformation of Ferrite-Austenite Banded Structure in Cold-Rolled Duplex Steel / Odkształcenie Pasmowej Struktury Ferrytu I Austenitu W Walcowanej Na Zimno Stali Duplex
Authors: Ryś J. , Zielińska-Lipiec A. 
Published: June 2015

Duplex type ferritic-austenitic stainless steels develop a specific two-phase banded structure upon thermo-mechanical pre-treatment and subsequent cold-rolling. The band-like morphology of ferrite and austenite imposes different conditions on plastic deformation of both constituent phases in comparison to one-phase ferritic and austenitic steels.
In the present research the ingot of a model ferritic-austenitic steel of duplex type, produced by laboratory melt, was subjected to preliminary thermo-mechanical treatment including forging and solution annealing. Afterwards cold-rolling was conducted over a wide deformation range. The investigations comprised examination of ferrite and austenite microstructures by means of optical and transmission electron microscopy and texture measurements after selected rolling reductions.
The presented results indicate that deformation mechanisms operating within the bands of both constituent phases are essentially the same as compared to one-phase steels, however their appearance and contribution are changed upon deformation of two-phase banded structure. Different deformation behavior within ferrite-austenite bands in duplex steels, visible especially at higher strains, considerably affects microstructure evolution and in consequence texture formation in both phases.
