Abstract
The Haemostasis Traffic Light is a cognitive aid with a user-centred design to enhance and simplify situation awareness and decision-making during peri-operative bleeding. Its structure helps to prioritise therapeutic interventions according to the pathophysiology and the severity of the bleeding. This investigator-initiated, randomised, prospective, international, dual-centre study aimed to validate the Haemostasis Traffic Light by adapting it to the local coagulation protocols of two university hospitals. Between 9 January and 12 May 2020, we recruited 84 participants at the University Hospital Zurich, Switzerland, and the Italian Hospital of Buenos Aires, Argentina. Each centre included 21 resident and 21 staff anaesthetists. Participants were randomly allocated to either the text-based algorithm or the Haemostasis Traffic Light. All participants managed six bleeding scenarios using the same algorithm. In simulated bleeding scenarios, the design of the Haemostasis Traffic Light algorithm enabled more correctly solved cases, OR (95%CI) 7.23 (3.82-13.68), p < 0.001, and faster therapeutic decisions, HR (95%CI) 1.97 (1.18-3.29, p = 0.010). In addition, the tool improved therapeutic confidence, OR (95%CI) 4.31 (1.67-11.11, p = 0.003), and reduced perceived work-load coefficient (95%CI) -6.1 (-10.98 to -1.22), p = 0.020). This study provides empirical evidence for the importance of user-centred design in the development of haemostatic management protocols.

Abstract
In patients with pre-operative anaemia undergoing cardiac surgery, combination treatment with intravenous iron, subcutaneous erythropoietin alpha, vitamin B12 and oral folic acid reduces allogeneic blood product transfusions. It is unclear if certain types of anaemia particularly benefit from this treatment. We performed a post-hoc analysis of anaemic patients from a randomised trial on the 'Effect of ultra-short-term treatment of patients with iron deficiency or anaemia undergoing cardiac surgery'. We used linear regression analyses to examine the efficacy of a combination anaemia treatment compared with placebo on the following deficiencies, each representing a part of the combination treatment: ferritin and transferrin saturation; endogenous erythropoietin; holotranscobalamine; and folic acid in erythrocytes. Efficacy was defined as change in reticulocyte count from baseline to the first, third and fifth postoperative days and represented erythropoietic activity in the immediate peri-operative recovery phase. In all 253 anaemic patients, iron deficiency was the most common cause of anaemia. Treatment significantly increased reticulocyte count in all regression analyses on postoperative days 1, 3 and 5 (all p < 0.001). Baseline ferritin and endogenous erythropoietin were negatively associated with change in reticulocyte count on postoperative day 5, with an unstandardised regression coefficient B of -0.08 (95%CI -0.14 to -0.02) and -0.14 (95%CI -0.23 to -0.06), respectively. Quadruple anaemia treatment was effective regardless of the cause of anaemia and its effect manifested early in the peri-operative recovery phase. The more pronounced a deficiency was, the stronger the subsequent boost to erythropoiesis may have been.

Abstract
IntroductionAccording to the dopamine hypothesis functional brain abnormalities and neurochemical alterations may converge to cause psychosis through aberrant salience attribution. Indeed, resting-state functional magnetic resonance imaging (rs-fMRI) has revealed widespread brain disconnectivity across the psychotic spectrum.ObjectivesTo advance the understanding of the dopaminergic involvement in intrinsic functional connectivity (iFC) and its putative relationship to the development of psychotic disorders we aimed to investigate the link between L-Dopa, a dopamine precursor, and its modulation of striatal iFC in subthreshold psychosis, i.e. non-clinical psychosis.MethodsWe used a randomized, double-blind placebo controlled study design including in our sample 56 healthy, male, right-handed, subjects with no familiar risk factors for psychosis who were assessed with the Schizotypal Personality Questionnaire (SPQ) and underwent 10 minutes of rs-fMRI scanning. All subjects received either 250 mg of Madopar DR®(200 mg L-Dopa plus 50 mg benserazid, dual release form) or a placebo. We analysed resting-state iFC of 6 striatal seeds, known to evoke dopamine related networks.ResultsThe main effect of L-Dopa presented itself (FWE-corrected) as a significant decrease in iFC from the right ventral striatum to the cerebellum and the precuneus cortex, and an increase in iFC to the occipital cortex. Subjects with high SPQ positive symptom sub-scores showed a significant increase of L-Dopa induced connectivity.ConclusionWe identified striatal functional connectivity being modulated by augmented dopamine availability, and in support of the dopamine hypothesis, we found that those iFC patterns are associated to high scores of psychotic like experiences.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
The therapy of vascular tumors and malformations should be interdisciplinary and performed according to available guidelines. Infantile hemangiomas (IH) are the most frequent vascular tumors of childhood and do not require treatment in most cases. If the IH is complicated by its location (e.g. facial or genital) or if the lesion threatens to cause loss of function, small localized IH should be treated by laser- or cryotherapy. If the IH is diffuse or rapidly growing it can be successfully treated using the β blocker propranolol. The mechanism underlying the efficacy of this medication-based therapy is not completely understood and this still represents an experimental therapy. The results of molecular studies on vascular malformations have indicated new strategies for medical therapies. However, lymphatic malformations (LM) are still treated by surgery where possible, or sclerotherapy. Further investigations are necessary to determine whether new drugs such as the mTOR inhibitor rapamycin may be effective for treatment of diffuse LM. First case reports seem to be promising.

Abstract
Angiogenesis is crucial for the growth of cancer. As such, it has become an established target in fighting cancer. Metronomic chemotherapy-the chronic administration of chemotherapy at relatively low, minimally toxic doses on a frequent schedule of administration at close regular intervals, with no prolonged drug-free breaks-is a potential novel approach to controlling advanced cancer disease. It is thought to work primarily through antiangiogenic mechanisms and has the property of killing resistant cancer cells while significantly reducing undesirable toxic side effects. We review the data regarding the use of metronomic chemotherapy in children with cancer and discuss its potential uses and limits.

Abstract
Silicon nanowires have been grown with gallium as catalyst by plasma enhanced chemical vapor deposition. The morphology and crystalline structure has been studied by electron microscopy and Raman spectroscopy as a function of growth temperature and catalyst thickness. We observe that the crystalline quality of the wires increases with the temperature at which they have been synthesized. The crystalline growth direction has been found to vary between <111> and <112>, depending on both the growth temperature and catalyst thickness. Gallium has been found at the end of the nanowires, as expected from the vapor-liquid-solid growth mechanism. These results represent good progress towards finding alternative catalysts to gold for the synthesis of nanowires.

Abstract
Focus on new drug development over the last few years has yielded new agents that differ from unspecific classical chemotherapeutics and ionizing radiation, while still targeting the cancer cell itself. Antiangiogenesis is a totally distinct approach targeting the tumor's blood vessels. This concept has now found its eligibility for the treatment of several adult solid tumors: the human antivascular endothelial growth factor (VEGF) antibody bevacizumab, as well as the VEGF receptor tyrosine kinase inhibitors, sunitinib and sorafinib, have recently been licensed by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMEA) for the treatment of colorectal, renal, and lung cancer. Other antiangiogenic drugs are under preclinical and early clinical evaluation. However, what do we know of the use of these drugs in pediatric solid tumors, such as sarcomas and embryonal and neuronal tumors? For some time now, neuroblastoma has been shown to be dependent on angiogenesis. However, the first preclinical data on antiangiogenic drugs in neuroblastoma have not been published until recently, and clinical trials with antiangiogenic agents in neuroblastoma treatment protocols are scarce. This review adresses current knowledge on the important role and mechanisms of angiogenesis in neuroblastoma and summarizes available preclinical and clinical results of antiangiogenic agents used to treat neuroblastoma. Our review clearly demonstrates that clinical trials are urgently needed to bring forward promising antiangiogenesis concepts in neuroblastoma therapy.

Abstract
Klippel-Trenaunay and Parkes Weber (Klippel-Trenaunay-Weber) syndromes consist of vascular malformations of the capillary, venous and lymphatic systems combined with soft tissue and bone hypertrophy of the affected extremity. Klippel-Trenaunay syndrome is a pure low-flow condition, while Parkes Weber syndrome is characterized by significant arteriovenous fistulas. The distinction of both entities is relevant, since the prognosis and therapeutic strategies differ significantly. Our purpose is to demonstrate that thick-slice dynamic magnetic resonance projection angiography (MRPA) is a non-invasive tool to detect arteriovenous shunting in Parkes Weber syndrome. Four patients underwent MR imaging and MRPA. MRPA demonstrated arteriovenous shunting in three patients. Arteriovenous shunting was characterized by early appearing draining veins. The time of arrival between normal arteries and pathological veins varied between less than 0.5 and 1.0 s. Therefore, the diagnosis in these cases could be specified as Parkes Weber syndrome. In all these cases, arteriovenous shunting was confirmed by intraarterial digital subtraction angiography. One patient showed normal results in MRPA and could be diagnosed as having Klippel-Trenaunay syndrome.

Abstract
Extracranial vascular anomalies can be divided into haemangiomas and vascular malformations. The latter can be subdivided on the basis of the predominant type of vascular channels. Separation of high- and low-flow vascular malformations is of clinical importance. We report preliminary observations on time-resolved magnetic resonance projection angiography (MRPA) of vascular malformations of the head and neck. We examined eight patients with vascular anomalies of the head and neck. On MRPA the time between the early arterial phase and enhancement of the malformation could be used to distinguish high- and low-flow lesions. High-flow arteriovenous malformations showed early, intense enhancement. Venous malformations were either not visible on MRPA or showed late enhancement of veins. One patient was examined after embolisation of an arteriovenous fistula of the mandible. Normal MRPA was taken to indicate absence of a residual lesion.

Abstract
Humoral angiogenesis stimulators including vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) have been implicated in the pathogenesis of solid malignancies. However, it has remained unclear whether both stimulators contribute to the development and progression of solid malignancies of children. The aim of the present study was to determine whether VEGF and bFGF are elevated in body fluids of children with solid malignancies and, if so, whether these elevated levels correlate with clinical parameters. Using enzyme-linked immunosorbent assays (ELISAs), we quantified VEGF and bFGF in serum (n = 107) and urine (n = 57) of healthy children and of children with solid malignancies (serum: n(VEGF) = 69, n(bFGF) = 60; urine: n(VEGF) or n(bFGF) = 13). Finally, we compared patients' pre-therapeutic and post-therapeutic levels. Serum VEGF was elevated in children with several solid tumors (Ewing's sarcoma, primitive neuroectodermal tumours, malignant lymphoma, Langerhans cell histiocytosis and medulloblastoma). In contrast, serum bFGF, urinary bFGF or urinary VEGF were not significantly elevated. Upon successful therapy, elevated pre-therapeutic serum VEGF levels declined to levels present in healthy children. VEGF could contribute to the progression of pediatric solid malignancies, and serum VEGF could be used to monitor therapeutic response. Furthermore, the determination of angiogenesis stimulators could identify patients eligible for anti-angiogenic therapy.

Abstract
UNLABELLED Primary lymphoma of bone (PLB) is a rare entity of extranodal non-Hodgkin lymphoma (NHL). We report on two children with PLB focussing on diagnostic evaluation and treatment strategy. Clinical and radiographic presentation in both children suggested a primary bone tumour such as Ewing sarcoma. A 13-year-old girl showed osteolytic tumours in the right 7th rib and right iliac crest. Additional skeletal lesions were found by whole-body positron emission tomography. A 6-year-old boy presented with an isolated, osteolytic lesion of the left distal femur. In both patients staging procedures excluded any organ involvement besides the skeletal tumours. Tumour biopsy and immunohistological studies revealed lymphoblastic non-Hodgkin lymphoma of B-cell lineage in both children. They received a polychemotherapy for B-cell lymphoma according to the NHL-BFM 95 protocol and are in complete remission with a follow up of 24 and 18 months respectively. CONCLUSION Isolated, primary lymphoma of bone in children may clinically and radiographically impose as primary bone tumour. Multiple therapeutic strategies have been applied in the treatment of this malignancy, however, treatment modalities are not well focussed on immunological patterns in the case of primary lymphoma of bone. Staging techniques should include immunophenotyping to initiate specific cell lineage treatment.

Abstract
We have examined the effect of hypoxia and nutrient depletion on the growth of human neuroblastoma cells with normal or enhanced expression of the N-myc oncogene. The combination of both conditions reduced the growth of neuroblastoma cells with normal N-myc expression. However, this effect was much more pronounced in neuroblastoma cells with enhanced N-myc expression and eventually resulted in apoptosis, presumably by the up-regulation of CD95. Our data suggest that therapeutic induction of tumor hypoxia and nutrient depletion (for example, by anti-angiogenesis) could help to improve the outcome of patients with neuroblastomas carrying the prognostically unfavourable N-myc amplification.

Abstract
Angiogenesis, the formation of new blood vessels, is seen during embryonic development and tumor progression, but the mechanisms have remained unclear. Recent data indicate that developmental and tumor angiogenesis can be induced by cellular oncogenes, leading to the enhanced activity of molecules stimulating angiogenesis. However, activated oncogenes might also facilitate angiogenesis by down-regulating endogenous inhibitors of angiogenesis. We report here that enhanced expression of the N-myc oncogene in human neuroblastoma cells down-regulates an inhibitor of endothelial cell proliferation, identified by amino acid sequencing as being identical with activin A, a developmentally regulated protein. Down-regulation appears to involve interaction of the N-Myc protein with the activin A promoter. In addition, activin A inhibits both endothelial cell proliferation in vitro and angiogenesis in vivo, and it induces hemorrhage in vivo. We suggest that the N-myc-induced down-regulation of activin A could contribute to developmental and tumor angiogenesis.

Abstract
N-myc oncogene amplification is frequent in human neuroblastoma and predicts poor prognosis, but the molecular consequences have remained obscure. We report here that enhanced N-myc expression correlates with low or undetectable expression of activin A, but not other closely related members of the transforming growth factor-beta superfamily. N-myc interacts with the activin A promoter, eventually inducing down-regulation of activin A mRNA and protein. This study demonstrates for the first time N-myc-induced down-regulation of a gene implicated in signal transduction. Down-regulation of activin A could deprive neuroblastomas from a signal with growth-inhibitory activities toward the tumor and its stroma and thereby permit neuroblastoma progression.

Abstract
The congenital dyserythropoietic anemias (CDA) are hereditary diseases characterized by a lifelong, mostly moderate anemia. CDA can be diagnosed already in early childhood. However, diagnosis is complicated due to poor knowledge of morphological criteria and the large number of differential diagnoses that have to be excluded. CDA type I is characterized by macrocytic anemia with megaloblastic changes in erythropoiesis and chromatin bridges between isolated erythroblasts. Type II shows a normocytic anemia with a positive acidified serum test and increased agglutination with anti-i. Erythroblasts can present with 2 or more nuclei. CDA type III presents with a macrocytic anemia and erythroblasts with up to 12 nuclei, the so called gigantoblasts. Some patients lack the typical morphological abnormalities of type I-III (variants or type IV). Besides light microscopic abnormalities, CDA type-specific changes in electron microscopy are described. The clinical picture of the patients vary between the different forms: signs of hemolysis and ineffective erythropoiesis such as icterus, splenomegaly and gall stones can be present. Most important is the tendency of a part of patients to have an increased iron absorption and iron storage. Patients with and without transfusion dependency are described. Supportive care such as iron chelation can be necessary in some patients. The CDA are inherited in an autosomal recessive manner; in type III an additional autosomal dominant variant exists. Recently, the determination of gene loci for type I, II and III was enabled by linkage analysis on different regions of chromosome 15 and 22. It is considered that CDA I and II are genetically heterogenic. Until now no gene has been identified in either type of CDA. In CDA type II, a glycosylation defect of erythrocyte membrane proteins is present. An international group plans to do further research. Therefore, identification and registration of patients in a registry is necessary. Patients' data and material would enable gene characterization. The results would allow an extended classification according to genotype and prediction of the course of the disease. Additionally, information on the regulation and control of normal and abnormal erythropoiesis could be obtained.

Abstract
Recent evidence indicates that the genetic alterations of the multistage process of malignant transformation appear to activate tumor neovascularization by altering the balance between stimulators and inhibitors of angiogenesis. In the present study, we have attempted to define the effect of enhanced MYCN oncogene expression on the profile of endothelial cell growth modulators in neuroblastoma cells. We report here that conditioned medium of human neuroblastoma cells with normal MYCN expression contains three inhibitors of endothelial cell proliferation, which appear to be novel proteins as judged by their physicochemical, immunological and biological properties. All three inhibitors are diminished or become undetectable upon experimental increase of MYCN expression. Our results suggest that enhanced MYCN expression in human neuroblastoma cells alters the angiogenic balance by down-regulating endothelial cell growth inhibitors but leaving the expression of the stimulators unaffected. These data shed light on the molecular mechanisms linking the genetic changes of malignant transformation with initiation of tumor angiogenesis. Moreover, our observations might explain the poor prognosis of human neuroblastomas following MYCN oncogene amplification through initiation of angiogenesis and subsequent tumor growth and spread.

Abstract
We have previously demonstrated that arginine deiminase inhibits the proliferation of vascular endothelial cells, but the mechanisms leading to growth inhibition have remained unclear. We report here that low concentrations of arginine deiminase purified from Mycoplasma arginini inhibit proliferation of various cultured cells by arresting the cell cycle in G(1) and/or S phase with higher arginine deiminase concentrations leading to subsequent apoptosis. Our results demonstrate that arginine deiminase inhibits cell proliferation not only by depletion of arginine, but also by mechanisms involving the cell cycle and death signals.

Abstract
Enhanced angiogenesis apparently contributes to the poor clinical outcome of human neuroblastoma, but the mechanisms have remained unclear. We report here that cultured human neuroblastoma cells express a bioactive endothelial cell growth factor indistinguishable from the angiogenesis stimulator vascular endothelial growth factor (VEGF). VEGF is present in neuroblastoma but not vascular endothelial cells, whereas the corresponding VEGF receptors (Flt-1 and Flk-1/KDR) are expressed in endothelial but not neuroblastoma cells. Exposure of neuroblastoma cells to hypoxia induces a marked increase in bioactive VEGF. VEGF is also present in human neuroblastoma specimens, with substantial amounts in apparently hypoxic neuroblastoma cells, eventually accumulating in tumor microvessels. Our results indicate that VEGF (i) is present in human neuroblastomas, (ii) is up-regulated by tumor hypoxia and (iii) may stimulate neuroblastoma angiogenesis by paracrine mechanisms, thereby contributing to the progression of human neuroblastomas. We suggest that inhibition of VEGF activity may represent a novel approach for the therapy of human neuroblastoma.

Abstract
Ionised and total magnesium concentrations were determined in the serum of different groups of patients suffering from renal or hepatic diseases. Ionised magnesium was measured by Microlyte 6 (KONE, Espoo, Finland) and total magnesium by atomic absorption spectrometry. In renal insufficiency ionised and total magnesium concentrations were almost equally increased. In proteinuria with a normal glomerular filtration rate, "pseudohypomàgnesaemia" was observed, i.e. decreased total magnesium concentration in parallel with a decreased albumin concentration with no significant change in the concentration of ionised magnesium. Hypermagnesaemia occurred in liver diseases combined with renal insufficiency, whereas "pseudohypomagnesaemia" was most often found in the absence of renal failure. Also treatment with an aldosterone antagonist was associated with a normal ionised magnesium concentration, but the total magnesium concentration was decreased; when additional magnesium was administered, the total magnesium concentration approached a normal value, while ionised magnesium slightly exceeded reference values. Only during cyclosporin treatment did both ionised and total magnesium concentrations become lowered. However, the decrease of total magnesium exceeded that of ionised magnesium due to concomitant hypoalbuminaemia with reduction of the protein-bound fraction. It is concluded that especially low total magnesium concentrations should be investigated by measurement of ionised magnesium to exclude "pseudohypomagnesaemia".

Abstract
Clinical and experimental findings in idiopathic amyothrophic lateral sclerosis (ALS) would be compatible with a retroviral involvement. In 35 adult patients with non-familial ALS we observed elevated circulating immune complexes, a decrease in IgG3 isotype and enzyme-linked sorbent assay (ELISA) serum antibodies against human spuma retrovirus (HSRV), confirmed by specific human foamy virus immunoblots. All 35 were negative for IgM or relevant IgG anti-ganglioside antibodies. We treated 12 HIV-negative, immune-complex-positive ALS patients with 500 mg d-1 zidovudine p.o. over 2-10 months and found reductions of serum creatine kinase and circulating immune complexes from two days to two weeks after the beginning of medication.

Abstract
Serum samples collected from patients with a wide variety of diseases from African and other countries were tested for antibodies to the human spumaretrovirus (HSRV). A spumaviral env-specific ELISA was employed as screening test. Out of 3020 human sera screened, 106 were found to be positive (3.2%). While the majority of patients' sera from Europe (1581) were negative, 26 were positive (1.6%). Sera from healthy adult blood donors (609), from patients with multiple sclerosis (48), Graves' disease (45), and chronic fatigue syndrome (41) were negative or showed a very low prevalence for spumaviral env antibodies. A higher percentage of seropositives (6.3%) were found among 1338 African patients from Tanzania, Kenya, and Gabon. Out of 1180 patients from Tanzania, 708 suffered from tumors, 75 from AIDS, and 128 had gynecological problems; 51 of the Tanzanian patients were HSRV seropositive (4.3%). A particularly high percentage of 16.6% seropositives were identified among nasopharyngeal carcinoma patients (NPC) from Kenya and Tanzania consistent with results reported 10 years ago. However, 20 nasopharyngeal carcinoma patients from Malaysia were HSRV-seronegative. In selected cases, sera from seropositive individuals were reacted with proteins from HSRV-infected cells in vitro. HSRV env- and gag-specific antibodies were specifically detected by these sera in Western blots. The results indicate spumavirus infections in human patients with various diseases at a relatively low prevalence worldwide; in African patients, however, the prevalence of spumavirus infections is markedly higher.

Abstract
Sixty patients with mammary cancer were studied in order to determine whether a connection between the tendency to delay medical treatment and a neurotic personality structure exists. The results are based on different personality factors that were investigated by means of the 16-PF test by Cattell. It could be shown that for patients who had delayed treatment (D2) the personality traits "limited inner tension" and "slightly inhibited" were present. On the other hand patients who had not delayed treatment (K1) displayed the personality traits "higher inner tension" and "free of inhibitions".
