Abstract
Abstract
Background
Inter-sectoral coalitions are regarded as a key principle of health promotion. The study examines the questions of how these are defined, which scientific theories and models are available, and which methods and parameters are used for their evaluation.
Methods
The scoping review in three databases (PubMed, Web of Science, LIVIVO) included studies in English and German published in 1/2010 to 5/2018. The results were analyzed qualitatively. In addition, relevant websites and textbooks in the field of public health, health promotion and social work were subjected to a document analysis in an iterative procedure.
Results
The database searches yielded 186 hits, of which 48 publications were systematically examined. Document analysis revealed 128 materials. Six common terms on inter-sectoral cooperation (network, collaboration, partnership, coalition, cooperation, alliance) were identified. Uniform definitions and unambiguous distinctions do not exist. Overall, only a few of the identified inter-sectoral collaborations are theoretically based, nine publications present models. Only seven studies provide insights into the effectiveness of model/theory-based strategies, whereby these almost exclusively examine output parameters. In particular, there are parameters on structure and process (e.g. team functioning, coalition capacity). Qualitative success factors and barriers were identified (e.g. integration of different actors, development of new financial sources, formalization). Eight validated instruments are identified. Four studies also examine the outcome level and demonstrate intended effects on behavioral parameters.
Conclusions
For research and practice, it is necessary to sharpen the terminology of intersectoral cooperation. Existing models should be systematically used and evaluated. In the future, an evaluation of the outcome of inter-sectoral cooperation and long-term effects will be increasingly necessary.
Key messages
Inter-sectoral coalitions are an evolving field, and both their theoretical foundation and empirical testing are still in their infancy. While success factors are well investigated, evaluations at the outcomes level are particularly necessary.

Abstract
Soft tissue sarcomas with smooth muscle differentiation are termed leiomyosarcoma. Leiomyosarcoma is an aggressive tumor commonly originating from smooth muscle cells of uterus or retro peritoneal areas. Distant metastasis occurs by hematogenous route to liver and lung. Eyelid metastasis without involvement of other ocular structures is extremely rare. A case of eyelid metastasis which on extensive investigations was proved to be from upper gastrointestinal tract leiomyosarcoma is reported here.

Abstract
Approximate one-dimensional (1D) as well as 2D and 3D simulations are playing an important supporting role in the design and analysis of future experiments at National Ignition Facility. This paper is mainly concerned with 1D simulations, used extensively in design and optimization. We couple a 1D buoyancy-drag mix model for the mixing zone edges with a 1D inertial confinement fusion simulation code. This analysis predicts that National Ignition Campaign (NIC) designs are located close to a performance cliff, so modeling errors, design features (fill tube and tent) and additional, unmodeled instabilities could lead to significant levels of mix. The performance cliff we identify is associated with multimode plastic ablator (CH) mix into the hot-spot deuterium and tritium (DT). The buoyancy-drag mix model is mode number independent and selects implicitly a range of maximum growth modes. Our main conclusion is that single effect instabilities are predicted not to lead to hot-spot mix, while combined mode mixing effects are predicted to affect hot-spot thermodynamics and possibly hot-spot mix. Combined with the stagnation Rayleigh-Taylor instability, we find the potential for mix effects in combination with the ice-to-gas DT boundary, numerical effects of Eulerian species CH concentration diffusion, and ablation-driven instabilities. With the help of a convenient package of plasma transport parameters developed here, we give an approximate determination of these quantities in the regime relevant to the NIC experiments, while ruling out a variety of mix possibilities. Plasma transport parameters affect the 1D buoyancy-drag mix model primarily through its phenomenological drag coefficient as well as the 1D hydro model to which the buoyancy-drag equation is coupled.

Abstract
Asymmetry is required by most numerical simulations of stellar core-collapse explosions, but the form it takes differs significantly among models. The spatial distribution of radioactive (44)Ti, synthesized in an exploding star near the boundary between material falling back onto the collapsing core and that ejected into the surrounding medium, directly probes the explosion asymmetries. Cassiopeia A is a young, nearby, core-collapse remnant from which (44)Ti emission has previously been detected but not imaged. Asymmetries in the explosion have been indirectly inferred from a high ratio of observed (44)Ti emission to estimated (56)Ni emission, from optical light echoes, and from jet-like features seen in the X-ray and optical ejecta. Here we report spatial maps and spectral properties of the (44)Ti in Cassiopeia A. This may explain the unexpected lack of correlation between the (44)Ti and iron X-ray emission, the latter being visible only in shock-heated material. The observed spatial distribution rules out symmetric explosions even with a high level of convective mixing, as well as highly asymmetric bipolar explosions resulting from a fast-rotating progenitor. Instead, these observations provide strong evidence for the development of low-mode convective instabilities in core-collapse supernovae.

Abstract
The combination of lenalidomide and dexamethasone (Len-Dex) is a commonly used initial therapy for newly diagnosed multiple myeloma (MM). Although the initial response rates and toxicity are well known, long-term outcome is not well described. We studied 286 consecutive patients with newly diagnosed MM initially treated with Len-Dex. The median (range) age at diagnosis was 63 (28-92) years, 166 (58%) patients ≤ 65 years and 175 (61%) male. The median estimated duration on Len-Dex was 5.3 months with overall response (≥ partial response) of 72%, including 26% with very good partial response or better. The median overall survival (OS) from the diagnosis was not reached (NR) and the estimated 5-year survival was 71%. The median time to first disease progression, irrespective of transplant status, was 30.2 months. Overall, 143 (50%) patients underwent stem cell transplant. The median OS was NR for patients ≤ 70 years and 5.8 years for the older patients (P=0.01). The 5-year OS estimate for patients in International Staging System stage 1, 2 and 3 were 82, 65, and 44% respectively. There were 21 new second malignancies after MM diagnosis (6.6%). The median survival exceeding 7 years reflects the efficacy of novel agents. The risk of second malignancies doesn't appear to be excessive in this population.

Abstract
Dental traumas are reasonably common, especially in children and adolescents. They are caused by many factors with fall accounting for the most frequent one. Dental trauma requires a special consideration when dental fractures accompany soft tissue lacerations. Dental fragments occasionally penetrate into soft tissue and may cause severe complications. Early diagnosis and surgical removal of these fragments could prevent undesirable foreign body reaction and scarring. This report presents immediate diagnosis and management of a case in which dental fragment was embedded in the lip soft tissue.

Abstract
PURPOSE To develop a library of graphic human models that closely match patients undergoing interventional fluoroscopic procedures in order to obtain an accurate estimate of their skin dose. METHODS A dose tracking system (DTS) has been developed that calculates the dose to the patient's skin in real time during fluoroscopic procedures based on a graphical simulation of the x-ray system and the patient. The calculation is performed using a lookup table containing values of mGy per mAs at a reference point and inverse-square correction using the distance from the source to individual points on the skin. For proper inverse-square correction, the external shape of the graphic should closely match that of the patient. We are in the process of developing a library of 3D human graphic models categorized as a function of basic body type, sex, height and weight. Two different open- source software applications are being used to develop graphic models with varying weights and heights, to 'morph' the shapes for body type and to 'pose' them for proper positioning on the table. The DTS software is being designed such that the most appropriate body graphic can be automatically selected based on input of several basic patient dimensional metrics. RESULTS A series of male and female body graphic models have been developed which vary in weight and height. Matching pairs have been constructed with arms at the side and over the head to simulate the usual placement in cardiac procedures. The error in skin dose calculation due to inverse-square correction is expected to be below 5% if the graphic can match the position of the patient's skin surface within 1 cm. CONCLUSIONS A library of categorized body shapes should allow close matching of the graphic to the patient shape allowing more accurate determination of skin dose with the DTS. Support for this work was provided in part by NIH grants R43FD0158401, R44FD0158402, R01EB002873 and R01EB008425, and by Toshiba Medical Systems Corporation.

Abstract
7671 Background: Brain metastases confer significant morbidity and a poorer survival in non-small cell lung cancer (NSCLC). Vascular endothelial growth factor-targeted antiangiogenic therapies (AAT) have demonstrated benefit for patients with metastatic NSCLC and are expected to directly inhibit the pathophysiology and morbidity of brain metastases, yet patients with brain metastases have been excluded from most clinical trials of AAT for fear of intracranial hemorrhage (ICH). This is a low suspected risk, but needs to be quantitated to plan clinical trials of AAT for NSCLC brain metastases. Methods: Data from MD Anderson Cancer Center Tumor Registry and electronic medical records from January 1998 to March 2006 was interrogated. 2143 patients with metastatic NSCLC registering from Jan 1998 to Sept 2005 were followed till March 2006. 776 patients with and 1367 patients without brain metastases were followed till death, date of ICH, or last date of study, whichever occurred first. Results: The incidence of ICH seemed to be higher in those with brain metastasis compared to those without. However, the rates of symptomatic ICH were not significantly different. All ICH patients with brain metastasis had received radiation therapy for them and were not anticoagulated. Most of the brain metastasis-associated ICH's were asymptomatic, detected during radiologic surveillance. The rates of symptomatic ICH, or cerebrovascular accidents were similar and not significantly different between the two groups. The following table depicts the rates of CVA and/or ICH in metastatic NSCLC patients. Conclusions: In metastatic NSCLC patients, the incidence of spontaneous ICH appeared to be higher in those with brain metastases compared to those without, but was very low in both groups nonetheless without a statistically significant difference. These data suggest minimal risk of clinically significant ICH for NSCLC brain metastasis patients and justifies for them clinical trials of AAT. No significant financial relationships to disclose.

Abstract
17080 Background: Lung is the most frequent organ site of metastases from non-small cell lung cancer (NSCLC), yet the impact of these metastases on the natural history of the disease has not been well elucidated. Part of the difficulty of evaluating the prognosis of lung metastases in NSCLC patients is the effect of metastases to other organ sites. Here we have studied the survival of patients with lung as the solitary or dominant site of metastases and correlated it with number and maximal size of tumors. Methods: Data from the M.D. Anderson Cancer Center Tumor Registry during 1998 to 2002 was interrogated. Of 1280 patients registering as new patients, 87 were evaluable as having lung as the only site of metastases on initial staging evaluation. Excluding 13 patients who had bronchioloalveolar carcinoma (BAC) or BAC features on histology, the remaining 74 patients’ baseline CT scans were reviewed and scored for 1) the maximal linear measurement of the largest lung tumor and 2) the number of lung nodules that were growing and consistent with lung metastases. Results: In non-BAC patients with lung only metastases, an inverse correlation is seen between maximal linear measurement of a patient’s largest lung metastasis on baseline staging and their subsequent survival. A similar inverse correlation is seen between the number of lung metastases and survival. When patients with subsequent development of other metastatic sites are excluded from the analysis, these correlations are strengthened. Also, in BAC patients with lung only metastases, a trend toward longer survival with fewer metastases was seen, but only 13 patients were evaluable. Formal statistical analysis of these results is pending. Conclusions: The number and size of lung metastases from NSCLC appear to be independent predictors of survival. This might be explained by lead-time bias where fewer lesions represent an earlier stage of metastatic disease, however, increasing number and size of metastases may also be multiplying the source for further metastatic spread of disease. This interpretation of data may justify the local therapy of individual lung metastases in oligometastatic disease by surgery, stereotactic radiosurgery, or radiofrequency ablation.

Abstract
4036 Background: Two-thirds of all pancreatic cancer patients have radiographically detectable metastatic disease at the time of diagnosis. Most of the remaining patients have locally advanced, unresectable disease that is typically treated with either chemoradiation or chemotherapy alone. We explored the possible benefit of the use of consolidative chemoradiation after induction chemotherapy. Methods: Between December 1993 and October 2005, 318 patients with locally advanced, non-metastatic, pancreatic cancer were treated at our institution with concurrent chemoradiation therapy. All patients underwent CT staging and biopsy confirmed adenocarcinoma. 245 patients received chemoradiation (CR) as initial treatment while 73 patients received a median of 2.5 months of induction chemotherapy prior to chemoradiation (CCR). Radiosensitizers included 5FU (42%), gemcitabine (39%) and capecitabine (19%) and most patients (88%) received 30 Gy of radiation therapy. The most common induction chemotherapy regimens were gemcitabine and cisplatin (73%) and gemcitabine alone (15%). Results: All statistics are actuarial and calculated from date of initial treatment. Median follow-up was 5.5 months (range 1–63 months). For all patients, overall survival was 9.0 months and 2-year survival was 8%. Age, gender, histology, grade, radiation fractionation and concurrent chemotherapy regimen had no impact on outcomes on univariate analysis. However, overall survival was 8.5 months in the CR group and 11.9 months in the CCR group (p = 0.0004). Median time to local progression was 6.0 months in the CR group and 8.4 in the CCR group (p = 0.0055). Median time to distant progression was 5.8 months in the CR group and 9.5 months in the CCR group (p=0.0136). Conclusions: In one of the largest series of locally advanced pancreatic cancer patients, the use of induction chemotherapy followed by chemoradiation seems to prolong median survival over initial treatment with chemoradiation. By excluding patients who progress rapidly during induction chemotherapy, this approach presumably selects patients most likely to benefit from a local treatment modality. This strategy merits prospective evaluation. [Table: see text]
