Abstract
ZusammenfassungZiel: Es wurde untersucht, ob eine Einführung radioaktiver Isotope von Yb und Y in ausgewählte Porphyrine möglich ist. Außerdem sollten erste Daten zur Bioverteilung von radioaktiven Yb-169-Porphyrin-Komplexen gewonnen werden. Methoden: Die Synthesen der Metall-Porphyrin-Komplexe erfolgten mit geträgerten Radiometallen. Erste Tierversuche wurden an Mammakarzinom-tragenden Mäusen durchgeführt. Die Organe wurden 5 und 24 h nach i.v.-lnjektion im Bohrlochdetektor gemessen. Ergebnisse: Es konnten vier Yb-169-Porphyrin-Komplexe und Y-90-Porphyrin-Komplexe in nicht trägerfreier Form synthetisiert werden. Dies wurde anhand der Absorptionsspektren sowie mittels DC und HPLC bewiesen. Je nach Komplex lagen die Tumor/Untergrund-Verhältnisse im Durchschnitt zwischen 2 und 20. Schlußfolgerung: Die synthetisierten radioaktiven Metall-Porphyrin-Komplexe zeigen eine deutliche Tumoraffinität, die bei weiterer Verbesserung der Synthese (Ziel: Trägerreduzierung, andere Radionuklide) eine Tumorszintigraphie und vielleicht -therapie ermöglichen könnte.

Abstract
Summary
Objectives: Comparison of the binding affinity to a CD30-positive Hodgkin lymphoma (HL) cell line and biodistribution in HL bearing mice of new anti-CD30 radioimmunoconjugates (RICs) of varying structure and labelling nuclides. Methods: The antibodies Ki-4 and 5F11 were radioiodinated by the chloramine T method or labelled with 111In via p-NCSBenzyl- DOTA. In addition, the Ki-4-dimer was investigated in the iodinated form. The RICs were analyzed for retained immunoreactivity by immunochromatography. In-vitro binding studies were performed on CD30-positive L540 cell lines. For in-vivo biodistribution studies, SCID mice bearing human HL xenografts were injected with the various radioimmunoconjugates. After 24 h, activities in the organs and tumour were measured for all 5 RICs. Tumour-free animals were studied in the same way with 131I- Ki-4 24 h p. i. The three RICs with the highest tumour/background ratios 24 h p.i. (131I-Ki-4, 131I–5F11, 111In-bz- DOTA-Ki-4) were analysed further at 48 h and 72 h. Results: All the RICs were successfully labelled with high specific activities (28–47 TBq/ mmol) and sufficient radiochemical yields (> 80%). Scatchard plot analysis proved high tumour affinity (KD = 20–220 nmol/l). In-vivo tumour accumulation in % of injected dose per g tissue (%ID/g) lay between 2.6 (131I-5F11) and 12.3 % ID/g (131I-Ki-4) with permanently high background in blood. Tumour/blood-ratios of all RICs were below one at all time points. Conclusions: In-vitro tumour cell affinities of all RICs were promising. However, in-vivo biokinetics tested in the mouse model did not meet expectations. This highlights the importance of developing and testing further new anti-CD30 conjugates.

Abstract
Summary
90Y-ibritumomab tiuxetan (Zevalin®) is currently approved for radioimmunotherapy of patients with relapsed or refractory follicular non-Hodgkin’s lymphoma pretreated with rituximab. Future directions are the combined use of 90Y-ibritumomab tiuxetan as part of the initial treatment and as first-line multi-agent therapy of relapsed disease. Current studies investigate patients with other than follicular indolent histologies, e. g. diffuse large cell lymphoma. Labelling of 90Y ibritumomab tiuxetan is a safe procedure, the radiochemical purity is not disturbed by a higher room temperature or by metallic impurity. Quality control is recommended by thin layer chromatography (TLC), strips >15 cm are favourable. TLC cannot distinguish between the correctly radiolabelled antibodies and radiocolloid impurity. If necessary, additional HPLC should be performed. Radiocolloid impurities are absorbed to the solid phase and do not reach the eluate. If the radiochemical purity test is insufficient (<95%), the additional cleaning using EconoPac 10 DG columns (Biorad, Hercules, CA, USA) is a reliable procedure to reduce the percentage of free radionuclide. However, this procedure is not part of the approval.

Abstract
Summary
Aim: The change of both amount and chemical forms of radioiodine exhaled in the air of rooms with patients on the therapy ward should be investigated depending on radioactivity applied, time after application, and kind of thyroid disease. Methods: The air of ward-rooms of 62 patients with thyroid carcinoma, Graves’ Disease, and autonomy which received different therapy doses, was investigated with an portable constant air flow sampler. Different chemical iodine species (organic, elemental, aerosol bound) were collected during 8 hr in various filters until 3 days after application of the radioiodine capsule, according to their chemical form. The radioactivity in the filters was measured with a well counter on defined time points after application. Results: The radioactivity exhaled was between 0,008 and 0,03% related to activity of radioiodine applied. The percentage of radioiodine exhaled related to the activity applied, differed significantly depending on disease and changed as follows: Grave’s Disease > autonomy > carcinoma. The exhalation of radioiodine became stronger with increasing applied activities and showed an exponential decrease with time. The most part of radioiodine was present in organic bound form. This organic portion decreased with time in favour of the other iodine species. Conclusion: The degree of accumulation of radioiodine orally applied within thyroid seems to be in direct proportion to the extend of its exhalation. Further measurements directly in the breathing air of RIT-patients are necessary, in order to clarify the relationship between degree of thyroid uptake and quantity as well as chemical form of radioiodine exhaled.

Abstract
BACKGROUND Social media presents an important means for social interaction, especially among adolescents, with Instagram being the most popular platform in this age-group. Pictures and communication about non-suicidal self-injury (NSSI) can frequently be found on the internet. METHODS During 4 weeks in April 2016, n = 2826 (from n = 1154 accounts) pictures which directly depicted wounds on Instagram were investigated. Those pictures, associated comments, and user accounts were independently rated for content. Associations between characteristics of pictures and comments as well as weekly and daily trends of posting behavior were analyzed. RESULTS Most commonly, pictures depicted wounds caused by cutting on arms or legs and were rated as mild or moderate injuries. Pictures with increasing wound grades and those depicting multiple methods of NSSI generated elevated amounts of comments. While most comments were neutral or empathic with some offering help, few comments were hostile. Pictures were mainly posted in the evening hours, with a small peak in the early morning. While there was a slight peak of pictures being posted on Sundays, postings were rather evenly spread across the week. CONCLUSIONS Pictures of NSSI are frequently posted on Instagram. Social reinforcement might play a role in the posting of more severe NSSI pictures. Social media platforms need to take appropriate measures for preventing online social contagion.

Abstract
BACKGROUND Conventional cervicofacial rhytidectomy has become the standard treatment of skin excess of the ageing neck. However, some patients want to avoid an extensive surgical procedure, especially if the anterior neck is the predominant problem zone. OBJECTIVE To report on the efficacy and safety of a zigzag-shaped skin excision combined with platysma plication. METHODS AND MATERIALS We present a retrospective case review series of six female patients. Skin excess was marked preoperatively using the skin pinching technique, then transferred to a zigzag-shaped area and finally excised using the method according to Tschopp, which is described. Patients were followed up for at least 1 year. RESULTS All patients (age: 55-82 years, median: 65 years) were very satisfied with the results. On an overall patient satisfaction scale of 1-10 (1 being the best), the scars were graded on average 1.85 (median: 2) 1 year after surgery. No scar hypertrophy, functional impairment, nerve damage or other serious complications were observed. CONCLUSION In selected patients, the direct anterior zigzag-shaped excision poses an effective, safe and easy surgical option for both skin excess and fat excess and platysma banding. The technique is easily reproducible, with low morbidity and high patient satisfaction.

Abstract
The miniaturization of complementary metal-oxide-semiconductor (CMOS) devices becomes increasingly difficult due to fundamental limitations and the increase of leakage currents. Large research efforts are devoted to find alternative concepts that allow for a larger data-density and lower power consumption than conventional semiconductor approaches. Spin waves have been identified as a potential technology that can complement and outperform CMOS in complex logic applications, profiting from the fact that these waves enable wave computing on the nanoscale. The practical application of spin waves, however, requires the demonstration of scalable, CMOS compatible spin-wave detection schemes in material systems compatible with standard spintronics as well as semiconductor circuitry. Here, we report on the wave-vector independent detection of short-waved spin waves with wavelengths down to 150 nm by the inverse spin Hall effect in spin-wave waveguides made from ultrathin Ta/Co8Fe72B20/MgO. These findings open up the path for miniaturized scalable interconnects between spin waves and CMOS and the use of ultrathin films made from standard spintronic materials in magnonics.

Abstract
BACKGROUND More and more people worldwide and also in Germany are using botulinum toxin type A (BoNT-A) and hyaluronic acid injections for skin rejuvenation. OBJECTIVE Study on body image and self-esteem of women with BoNT-A and/or hyaluronic acid filler treatment. MATERIAL AND METHODS A total of 145 women who requested BoNT-A and/or hyaluronic acid injections completed a survey comprised of the body dysmorphic disorder questionnaire, the Rosenberg self-esteem scale and questionnaires on the attitudes and motives on measures for optimization of the body and demographic features. Using this instrument data on the body image and self-esteem as well as attitudes and motives for utilization of minimally invasive skin rejuvenation were collated. RESULTS Female users of minimally invasive skin rejuvenation showed an overall higher socioeconomic status and an above average high monthly income. They lived in a partnership more often in comparison to women of equal age living in Berlin. The users of BoNT-A and/or hyaluronic acid fillers showed no conspicuous differences in body image and self-esteem. They showed a moderately positive attitude to body optimization procedures and 91% achieved their standard weight with a body mass index (BMI) of ≤25 kg/m2 in comparison to 56% of German women in the same age range (25 to ≥75 years old). CONCLUSION In the first study of body image and self-esteem in users of BoNT‑A and/or dermal fillers in German women, the users showed no signs of body dysmorphic patterns or disorders of self-esteem.

Pilot study of MRI/ultrasound fusion imaging in postpartum assessment of Cesarean section scar. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2017; 50:520-526. [PMID: 27804175 DOI: 10.1002/uog.17349] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/26/2016] [Revised: 09/17/2016] [Accepted: 10/21/2016] [Indexed: 06/06/2023]
Abstract
OBJECTIVE To evaluate prospectively the uterine scar after Cesarean section (CS) and the corresponding uterine region after vaginal delivery (VD) at 6 weeks postpartum using transabdominal (TAS) and transvaginal (TVS) sonography with magnetic resonance imaging (MRI) fusion to investigate whether fusion imaging allows standardized and reproducible identification of the scar location and measurement of uterine wall thickness compared with high-resolution MRI alone. METHODS Pelvic MRI was performed 6 weeks after delivery in 30 women (10 with planned CS (PCS), 10 with emergency CS (ECS) and 10 with VD). After transfer of MRI-DICOM datasets to the ultrasound system, the scar region after CS and the corresponding uterine region after VD were examined by TAS (5 MHz) and TVS (10 MHz) using smart fusion with MRI to guide visualization of the region in the corresponding sectional planes for both modalities. Vascularization of the scar region was determined as a percentage area using power Doppler ultrasound. Anterior (AW) and posterior (PW) uterine wall thickness was measured using TAS and TVS with fusion imaging and using MRI alone. RESULTS TVS with fusion imaging was applied successfully for uterine assessment at the end of the postpartum period in all women. TAS failed to identify the scar area in three women. Imaging techniques were similar in the evaluation of AW and PW thickness following VD. MRI and MRI/TVS fusion showed significant differences in AW thickness or scar area, in terms of the difference relative to PW thickness, in women with PCS and ECS (MRI: PCS, 4.3 mm; ECS, 4.2 mm; VD, 0.8 mm; P = 0.034; MRI/TVS fusion: PCS, 2.0 mm; ECS, 3.3 mm; VD, 0.0 mm; P = 0.01). The degree of vascularization in the scar region measured by power Doppler ultrasound was lower after PCS (13.1 ± 9.4%/area) and ECS (17.0 ± 8.2%/area) than after VD (34.6 ± 8.5%/area; P = 0.0017). CONCLUSION MRI/ultrasound fusion imaging can be performed in a reproducible manner for examination of the postpartum uterus. MRI/TVS fusion enables standardized identification of the CS scar location and vascularization is reduced in this area. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Therapy of ulcus cruris of venous and mixed venous arterial origin with autologous, adult, native progenitor cells from subcutaneous adipose tissue: a prospective clinical pilot study. J Eur Acad Dermatol Venereol 2017; 31:2104-2118.

Abstract
BACKGROUND The stromal vascular fraction (SVF) of adipose tissue consists of cellular subpopulations with distinct regenerative potential. OBJECTIVE To investigate the regenerative capacities of autologous SVF cells in the treatment of chronic leg ulcers of venous (VLU) and arterial-venous (AVLU) origin. METHODS Multimorbid ulcer patients received a singular topical treatment with 9-15 × 106 SVF cells, separated from abdominal lipoaspirates by digestion with collagenase and neutral protease and applied immediately after isolation. The primary endpoints were the change in wound size 12 weeks after treatment and evaluation of adverse events. Secondary endpoints included the time to complete wound epithelialization and change in pain levels. Postoperative wound treatment modalities and treatment of comorbidities were not intensified compared with pre-operative management. Follow-up period was at least 6 months. RESULTS Sixteen elderly ulcer patients (seven with VLU, nine with AVLU) were treated as described. All VLU patients (median ulcer size: 48.25 cm2 ) and four of nine AVLU patients showed complete epithelialization of the ulcers within 71-174 days. In three patients with large ulcerations on both legs, ulcerations on the non-treated, contralateral leg also epithelialized. Patients reported a considerable rapid decrease in pain intensity by 2.5 points on average on a visual scale from 1 to 5 within the first 2 weeks after treatment. The patients were followed up for 9-44 months (median: 30 months). No severe side-effects were observed. CONCLUSIONS The use of SVF cells presents an effective, minimally invasive option for the treatment of VLU and AVLU even in multimorbid patients. In patients with larger predominantly ischaemic AVLU and comorbidities, one-time application of the used amounts of SVF cells was not sufficient in the majority of cases.

Abstract
BACKGROUND Psoriasis is a disease of enormous socio-economic impact. Despite approval of numerous highly efficient and costly therapies, a minor proportion of severely affected patients actually receives sufficient treatment. OBJECTIVE To investigate whether addictions are associated with psoriasis and to develop evidence-based recommendations for dermatologists in their daily clinical practice in order to improve medical assessment of psoriasis and patients' quality of life. PATIENTS AND METHODS Psoriasis patients at the University Department of Dermatology were asked to fill out a paper-based self-reported anonymous questionnaire with 92 questions of validated screening tests for the six most common addictions in Germany (alcohol, nicotine, drugs and illegal drugs, gambling, food). Body weight and height as well as current Psoriasis Area and Severity Index (PASI) were documented as well. RESULTS Between October 2015 and February 2016, 102 patients (65 males, 37 females; mean age 49.7 years (SD 13.4), range 18-83 years) participated in the study. Fifty-seven of the 102 patients showed addictive behaviour. Of these, 23.8% were high-risk drinkers, 41% regular smokers, 11% at risk of drug abuse, 4.1% at risk of food dependency and 19% compulsive gamblers. Compared with the general population, these results are significantly higher for alcohol abuse (P < 0.005), nicotine (P < 0.001) and gambling (P < 0.001). Body mass index was significantly higher in the study population (P < 0.001). CONCLUSION Addictions and gambling are more prevalent in patients with psoriasis compared with the general population. Respective screening measures are recommended in daily practice for doctors treating psoriasis patients, and PeakPASI is suggested as a score to document patients' lifetime highest PASI. Parallel to new drug approvals and even more detailed insights into the pathomechanism of psoriasis, public health strategies and interdisciplinary approaches are essential for a general sustained psoriasis treatment.

Retention efficacy and release of radioiodine in fume hoods. JOURNAL OF ENVIRONMENTAL RADIOACTIVITY 2017; 166:175-180.

Abstract
Procedures to determine the release of hazardous gaseous substances including radioactive iodine are covered by different norms such as the European standard EN 14175 and the German national standard DIN 25466. The detection of sulphur hexafluoride (SF6) is required to comply with the prescribed methodology. The detection limit of this test is 4.5·10-7 mol/m3 in exhaust air. This detection limit would represent a very high activity in the region of 0.27 TBq/m3 leading to an unacceptable risk. We therefore developed a test using a filter system, consisting of a combination of filters capable of separating various chemical forms of airborne radioiodine. Air samples were collected directly in front of the fume hood and in the laboratory beside two different fume hoods of a similar construction with a final activated carbon filter for retention of radioiodine. Particular attention was therefore paid to air samples taken after passage over the filters. Significant differences in the degree of retention of iodine were found between the two fume hoods investigated. In one test a malfunction of the fume hood was demonstrated. In this case 0.148 × 10-3% of the total released activity per m3 air was found 1 cm in front of the hood sash. A remarkably high fraction of the activity released in the fume hood (1.3 × 10-3%/m3 air) was measured after the activated carbon filter. In the ambient air, values of up to 8.6 × 10-6% pro m3 laboratory air sampled were measured, despite a 6-8-fold air exchange. The selected procedure is a factor of 1011 (Schomäcker et al., 2001) more sensitive than the standard recommended methods (EN 14175). The standard test prescribed by the DIN/EN failed to reveal any inadequacy in the protective function of the radionuclide hood with respect to radioiodine retention.

Abstract
The protective effect of stable iodide against radiation on thyroid cells was investigated. One physiological effect of stable iodine is well-rooted: stable iodine leads to a reduced thyroid uptake of radioactive iodine. This work wants to focus on an intrinsic effect of stable iodine by which DNA-damage in cells is prevented. To investigate this intrinsic effect thyroid cells (FRTL-5) were externally irradiated by use of a linear accelerator (LINAC) applying energy doses of 0.01 Gy-400 Gy and by incubation with various activity concentrations of 131I (0.1-50 MBq/ml for 24 h). We added stable iodine (NaI) to the cells prior to external irradiation and investigated the effect of the concentration of stable iodine (1, 5, 15 μg/ml). In order to clarify whether thyroid cells have a distinctive and iodine-dependent reaction to ionizing radiation, keratinocytes (HaCaT) without NIS were exposed in the same way. As indicators for the cellular reaction, the extent of DNA fragmentation was determined (Roche, Mannheim, Germany). Both cell types showed distinct ability for apoptosis as proven with camptothecin. The addition of "cold" iodine from 1 to 15 μg/ml without irradiation ("negative control") did not change the response in both cell types. Plausibly, the radio-sensitivity of both cell types did increase markedly with increasing radiation dose but the radiation effect is diminished if iodine is added to the thyroid cells beforehand. The DNA-damage in thyroid cells after addition of cold iodine is reduced by a factor of 2-3. The skin cells did not show an significant change of radio-sensitivity depending on the presence of cold iodine. Elementary iodine possibly acts as a radical scavenger and thus markedly reduces the secondary radiation damage caused by the formation of cytotoxic radicals. This intrinsic radioprotective effect of iodine is seen only in cells with NIS.

Abstract
The new expert recommendation from the Austrian Society of Obstetrics and Gynaecology (OEGGG) comprises an interpretation and summary of guidelines from the leading specialist organisations worldwide (RCOG, ACOG, SOGC, CNGOF, WHO, NIH, NICE, UpToDate). In essence it outlines alternatives to the direct pathway to elective repeat caesarean section (ERCS). In so doing it aligns with international trends, according to which a differentiated, individualised clinical approach is recommended that considers benefits and risks to both mother and child, provides detailed counselling and takes the patient's wishes into account. In view of good success rates (60-85 %) for vaginal birth after caesarean section (VBAC) the consideration of predictive factors during antenatal birth planning has become increasingly important. This publication provides a compact management recommendation for the majority of standard clinical situations. However it cannot and does not claim to cover all possible scenarios. The consideration of all relevant factors in each individual case, and thus the ultimate decision on mode of delivery, remains the discretion and responsibility of the treating obstetrician.

Abstract
Magnonic spin currents in the form of spin waves and their quanta, magnons, are a promising candidate for a new generation of wave-based logic devices beyond CMOS, where information is encoded in the phase of travelling spin-wave packets. The direct readout of this phase on a chip is of vital importance to couple magnonic circuits to conventional CMOS electronics. Here, we present the conversion of the spin-wave phase into a spin-wave intensity by local non-adiabatic parallel pumping in a microstructure. This conversion takes place within the spin-wave system itself and the resulting spin-wave intensity can be conveniently transformed into a DC voltage. We also demonstrate how the phase-to-intensity conversion can be used to extract the majority information from an all-magnonic majority gate. This conversion method promises a convenient readout of the magnon phase in future magnon-based devices.

Abstract
INTRODUCTION As the accurate diagnosis and treatment of gestational diabetes mellitus (GDM) is of increasing importance; new diagnostic approaches for the assessment of GDM in early pregnancy were recently suggested. We evaluate the diagnostic power of an 'early' oral glucose tolerance test (OGTT) 75 g and glycosylated fibronectin (glyFn) for GDM screening in a normal cohort. METHODS AND ANALYSIS In a prospective cohort study, 748 singleton pregnancies are recruited in 6 centres in Switzerland, Austria and Germany. Women are screened for pre-existing diabetes mellitus and GDM by an 'early' OGTT 75 g and/or the new biomarker, glyFn, at 12-15 weeks of gestation. Different screening strategies are compared to evaluate the impact on detection of GDM by an OGTT 75 g at 24-28 weeks of gestation as recommended by the International Association of Diabetes and Pregnancy Study Groups (IADPSG). A new screening algorithm is created by using multivariable risk estimation based on 'early' OGTT 75 g and/or glyFn results, incorporating maternal risk factors. Recruitment began in May 2014. ETHICS AND DISSEMINATION This study received ethical approval from the ethics committees in Basel, Zurich, Vienna, Salzburg and Freiburg. It was registered under http://www.ClinicalTrials.gov (NCT02035059) on 12 January 2014. Data will be presented at international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT02035059.

Abstract
BACKGROUND A revised version of the PI-RADS scoring system has been introduced and score-related variability between version 1 and 2 may be suspected. This study aimed to assess the PI-RADS scores derived from version 1 (v1) and the updated version 2 (v2). MATERIAL AND METHODS 61 patients with biopsy-proven prostate cancer (PCa) and 90 lesions detected on pre-biopsy 3-Tesla multiparametric MRI were included in this retrospective analysis. 2 experienced radiologists scored all lesions in consensus. Lesion scores differing between PI-RADS v1 and v2 were further analyzed. Histology data from radical prostatectomy (RP) were included when available. RESULTS The PI-RADS v1 and v2 score differed in 52% of patients (32/61) and in 39% of lesions (35/90). On a lesion basis, the reason for the differences were related to sum score in v1 vs. categorical system in v2 in 51% (18/35) of lesions, cutoff between PI-RADS 4 and 5 based on lesion size in v2 as opposed to the sum score in v1 in 31% (11/35) and were inconclusive in 17% (6/35). The RP subgroup indicates enhanced detection of PCas with GS 3+3 and GS 3+4 in v2. CONCLUSION PI-RADS scores of prostatic lesions frequently differed between v1 and v2, the major reasons for these differences being score-related. In men undergoing RP, PI-RADS v2 improved detection of low risk PCa, but did not increase accuracy for discrimination of GS 3+4 vs. GS≥4+3 compared to v1. Urologists should be aware of the system-related differences when interpreting PI-RADS scores.

Abstract
Blood is known to be an extremely non-Newtonian material, the fluidity (or reciprocal of viscosity) of which can vary in vivo between that of plasma alone and zero, that is, the total lack of fluidity in the absence of coagulation. The fluidity of blood under high driving pressures and in small blood vessels is un usually high when compared to that of all other known suspensions or emul sions. The high fluidity of blood is caused by the fluidity of the red cells, which adapt to the forces of flow and participate in flow much like fluid droplets. When subjected to high forces the blood behaves dynamically like an emulsion of extremely low viscosity. In the absence of adequate flow forces, the erythro cytes are aggregated into rouleaux and rouleaux networks, which render to blood the properties of a reticulated suspension. Under these flow conditions, the fluidity of blood strongly decreases if the hematocrit value is normal or slightly elevated. If the flow forces fall below a critical level, the fluidity ap proaches zero, under which conditions the flow of blood ceases altogether (de spite the presence of residual driving pressures). The fluidity of blood is further jeopardized by an enhanced tendency to aggregation and biochemical erythro cyte rigidification, for example, by lactacidosis, hyperosmolarity, or loss of ATP. However, an actual loss of fluidity under these conditions occurs only if the biochemical changes are strictly associated with a drop in driving pressures (locally or generally). Restitution of blood fluidity can be achieved most simply by isovolumic he modilution, by defibrinogating agents, or by drugs that protect against rigid ifying effects of acidosis or other biochemical sequelae of stagnation anoxia.

Abstract
Background Mesonephric adenocarcinoma of the vagina is an extremely rare tumor of the female genital tract, with only a few cases reported so far worldwide. Consequently, there is no established standard treatment and limited knowledge about the prognosis and biologic behavior of vaginal mesonephric adenocarcinoma. Methods This report documents a new case of vaginal mesonephric adenocarcinoma diagnosed in a 54-year-old woman, and analyzes this in the context of all previously published cases. Results MRI demonstrated that the 2.5 × 1.8 cm tumor of the vaginal wall was invading urethra and bladder. Following surgical excision, histologic analysis determined mesonephric adenocarcinoma of the vagina, stage pT2 R1. In order to avoid the mutilating extended surgery which would be required to reach R0 and considerable impairment of quality of life, adjuvant radiochemotherapy was administered with external radiation and brachytherapy, including 5 cycles of cisplatin (40 mg/m²) for radiosensitization. After 4 years of continuous oncologic follow-up, the patient is alive and clinically free of disease. Conclusion In this case it was shown that adjuvant radiochemotherapy with radiation and brachytherapy was effective to manage the surgical R1 situation and maintain the patient’s life quality. More published cases reports are needed to gradually substantiate optimal treatment strategies.

Abstract
BACKGROUND Systems medicine is the name for an assemblage of scientific strategies and practices that include bioinformatics approaches to human biology (especially systems biology); "big data" statistical analysis; and medical informatics tools. Whereas personalized and precision medicine involve similar analytical methods applied to genomic and medical record data, systems medicine draws on these as well as other sources of data. Given this distinction, the clinical translation of systems medicine poses a number of important ethical and epistemological challenges for researchers working to generate systems medicine knowledge and clinicians working to apply it. DISCUSSION This article focuses on three key challenges: First, we will discuss the conflicts in decision-making that can arise when healthcare providers committed to principles of experimental medicine or evidence-based medicine encounter individualized recommendations derived from computer algorithms. We will explore in particular whether controlled experiments, such as comparative effectiveness trials, should mediate the translation of systems medicine, or if instead individualized findings generated through "big data" approaches can be applied directly in clinical decision-making. Second, we will examine the case of the Riyadh Intensive Care Program Mortality Prediction Algorithm, pejoratively referred to as the "death computer," to demonstrate the ethical challenges that can arise when big-data-driven scoring systems are applied in clinical contexts. We argue that the uncritical use of predictive clinical algorithms, including those envisioned for systems medicine, challenge basic understandings of the doctor-patient relationship. Third, we will build on the recent discourse on secondary findings in genomics and imaging to draw attention to the important implications of secondary findings derived from the joint analysis of data from diverse sources, including data recorded by patients in an attempt to realize their "quantified self." This paper examines possible ethical challenges that are likely to be raised as systems medicine to be translated into clinical medicine. These include the epistemological challenges for clinical decision-making, the use of scoring systems optimized by big data techniques and the risk that incidental and secondary findings will significantly increase. While some ethical implications remain still hypothetical we should use the opportunity to prospectively identify challenges to avoid making foreseeable mistakes when systems medicine inevitably arrives in routine care.

Abstract
Background A long-term analysis by the Early Breast Cancer Trialist Group (EBCTG) revealed a strong correlation between local control and cancer-specific mortality. MicroRNAs (miRs), short (20–25 nucleotides) non-coding RNAs, have been described as prognosticators and predictors for breast cancer in recent years. The aim of the current study was to identify miRs that can predict local control after breast conserving therapy (BCT) in early stage breast cancer. Results Clinical data of 46 early stage breast cancer patients with local relapse after BCT were selected from the institutional database. These patients were matched to 101 control patients showing identical clinical features but without local relapse. The study was conducted in two steps. (1) In the pilot study, 32 patients (16 relapses versus 16 controls) were screened for the most de-regulated microRNAs (= candidate microRNAs) in a panel of 1250 miRs by microarray technology. Eight miRs were found to be significantly de-regulated. (2) In the validation study, the candidate microRNAs were analyzed in an independent cohort of 115 patients (30 relapses versus 85 controls) with reverse transcription quantitative polymerase chain reaction (RT-qPCR). From these eight candidates, hsa-miR-375 could be validated. Its median fold change was 2.28 (Mann-Whitney U test, corrected p value = 0.008). In the log-rank analysis, high expression levels of hsa-miR-375 correlated with a significantly higher risk of local relapse (p = 0.003). In a multivariate analysis (forward stepwise regression) including established predictors and prognosticators, hsa-miR-375 was the only variable that was able to distinguish the statistical significance between relapse and control groups (raw p value = 0.000195 HR = 0.76, 95 % CI 0.66–0.88; corrected p value = 0.005). Conclusions Hsa-miR-375 predicts local control in patient with early stage breast cancer, especially in estrogen receptor α (ER-α)-positive patients. It can therefore serve as an additional molecular marker for treatment choice independently from known predictors and prognosticators. Validation in larger prospective studies is warranted.

Abstract
Background Pooled human platelet lysate (pHPL) is an efficient alternative to xenogenic supplements for ex vivo expansion of mesenchymal stem cells (MSCs) in clinical studies. Currently, porcine heparin is used in pHPL-supplemented medium to prevent clotting due to plasmatic coagulation factors. We therefore searched for an efficient and reproducible medium preparation method that avoids clot formation while omitting animal-derived heparin. Methods We established a protocol to deplete fibrinogen by clotting of pHPL in medium, subsequent mechanical hydrogel disruption and removal of the fibrin pellet. After primary culture, bone-marrow and umbilical cord derived MSCs were tested for surface markers by flow cytometry and for trilineage differentiation capacity. Proliferation and clonogenicity were analyzed for three passages. Results The proposed clotting procedure reduced fibrinogen more than 1000-fold, while a volume recovery of 99.5 % was obtained. All MSC types were propagated in standard and fibrinogen-depleted medium. Flow cytometric phenotype profiles and adipogenic, osteogenic and chondrogenic differentiation potential in vitro were independent of MSC-source or medium type. Enhanced proliferation of MSCs was observed in the absence of fibrinogen but presence of heparin compared to standard medium. Interestingly, this proliferative response to heparin was not detected after an initial contact with fibrinogen during the isolation procedure. Conclusions Here, we present an efficient, reproducible and economical method in compliance to good manufacturing practice for the preparation of MSC media avoiding xenogenic components and suitable for clinical studies.
