While health sciences offer data and models for preventing the development of NCDs through health promotion, they do not explain the dynamics between the different institutions and actors in the health field. Neofunctionalism refers to these different actors and suggests that their interaction leads to the construction of a supranational authority, allowing the actors to cooperate on common policies, rules and institutions, resulting in integration and Europeanization. Indeed, there are a variety of European Union (EU) institutions and policies concerned with physical activity (PA), however, the purpose of this paper is to analyze if Europeanization and integration are happening in PA promotion, through the lens of neofunctionalism. Analysis uses process tracing for investigating the emergence of PA on the EU agenda, the legal background, existing policies and institutions. Findings indicate that Europeanization and integration of PA promotion are happening, although the opportunity for actions of the EU are restricted to voluntary actions of the EU Member States due to the agreements in the Treaty of Lisbon. This only allows the EU institutions to apply soft law approaches on PA promotion, which seems to be implemented in some Member States despite its non-binding character. The findings are discussed and further implications for public health professionals and policies outlined.}, language = {en} } @article{CichyKruszwickaPalusetal., author = {Cichy, Ireneusz and Kruszwicka, Agnieszka and Palus, Patrycja and Przybyla, Tomasz and Schliermann, Rainer and Wawrzyniak, Sara and Klichowski, Michal and Rokita, Andrzej}, title = {Physical Education with Eduball Stimulates Non-Native Language Learning in Primary School Students}, series = {International Journal of Environmental Research and Public Health (Int.

This is surprising, because numerous studies show that integrating physical education (PE) with teaching content stimulates critical skills. For example, several experiments indicate that Eduball-based PE (i.e., lessons in a sports hall during which students play team mini-games with educational balls with printed letters, numbers, and other signs) develops mathematical and language competencies. At the same time, the Eduball method does not slow down learners' physical development. However, we have little knowledge about the effects of such techniques on non-native language learning. Consequently, the absence of incorporating core academic subjects into PE in dual-language schools or during foreign language education is exceptionally high. Here, we replicated the Eduball experiment, but with the goal of testing this method for non-native language learning. Thus, the intervention occurred in a dual-language primary school and we evaluated second language (L2) learning. As before, we used the technique of parallel groups (experimental and control); in both groups, there were three 45-min PE classes per week. In the experimental class, two of them were held using Eduball. After a half-year experiment, children from the experimental group (one second-grade, N = 14) improved their non-native language skills significantly more than their peers from the control group (one second-grade, N = 12). These findings demonstrate that Eduball-type intervention stimulates non-native language learning in children. Hence, our report suggests that specific body training forms can support L2 learning.}, language = {en} } @article{BenderFahriogluYamaciTaneri, author = {Bender, Guzide and Fahrioglu Yamaci, Rezan and Taneri, Bahar}, title = {CRISPR and KRAS: a match yet to be made}, series = {Journal of biomedical science}, volume = {28}, journal = {Journal of biomedical science}, publisher = {Springer Nature}, doi = {10.1186/s12929-021-00772-0}, pages = {1 -- 25}, abstract = {CRISPR (clustered regularly interspaced short palindromic repeats) systems are one of the most fascinating tools of the current era in molecular biotechnology. With the ease that they provide in genome editing, CRISPR systems generate broad opportunities for targeting mutations. Specifically in recent years, disease-causing mutations targeted by the CRISPR systems have been of main research interest; particularly for those diseases where there is no current cure, including cancer. KRAS mutations remain untargetable in cancer. Mutations in this oncogene are main drivers in common cancers, including lung, colorectal and pancreatic cancers, which are severe causes of public health burden and mortality worldwide, with no cure at hand. CRISPR systems provide an opportunity for targeting cancer causing mutations. In this review, we highlight the work published on CRISPR applications targeting KRAS mutations directly, as well as CRISPR applications targeting mutations in KRAS-related molecules. In specific, we focus on lung, colorectal and pancreatic cancers. To date, the limited literature on CRISPR applications targeting KRAS, reflect promising results. Namely, direct targeting of mutant KRAS variants using various CRISPR systems resulted in significant decrease in cell viability and proliferation in vitro, as well as tumor growth inhibition in vivo. In addition, the effect of mutant KRAS knockdown, via CRISPR, has been observed to exert regulatory effects on the downstream molecules including PI3K, ERK, Akt, Stat3, and c-myc. Molecules in the KRAS pathway have been subjected to CRISPR applications more often than KRAS itself. The aim of using CRISPR systems in these studies was mainly to analyze the therapeutic potential of possible downstream and upstream effectors of KRAS, as well as to discover further potential molecules. Although there have been molecules identified to have such potential in treatment of KRAS-driven cancers, a substantial amount of effort is still needed to establish treatment strategies based on these discoveries. We conclude that, at this point in time, despite being such a powerful directed genome editing tool, CRISPR remains to be underutilized for targeting KRAS mutations in cancer. Efforts channelled in this direction, might pave the way in solving the long-standing challenge of targeting the KRAS mutations in cancers.}, language = {en} } @article{ChatterjeeKobylinskiBasu, author = {Chatterjee, Subhomoy and Kobylinski, Sabine and Basu, Bikramjit}, title = {Finite Element Analysis to Probe the Influence of Acetabular Shell Design, Liner Material, and Subject Parameters on Biomechanical Response in Periprosthetic Bone}, series = {Journal of Biomechanical Engineering}, volume = {140}, journal = {Journal of Biomechanical Engineering}, number = {10}, publisher = {ASME}, issn = {1528-8951}, doi = {10.1115/1.4040249}, abstract = {The implant stability and biomechanical response of periprosthetic bone in acetabulum around total hip joint replacement (THR) devices depend on a host of parameters, including design of articulating materials, gait cycle and subject parameters. In this study, the impact of shell design (conventional, finned, spiked, and combined design) and liner material on the biomechanical response of periprosthetic bone has been analyzed using finite element (FE) method. Two different liner materials: high density polyethylene-20\% hydroxyapatite-20\% alumina (HDPE-20\%HA-20\%Al2O3) and highly cross-linked ultrahigh molecular weight polyethylene (HC-UHMWPE) were used. The subject parameters included bone condition and bodyweight. Physiologically relevant load cases of a gait cycle were considered. The deviation of mechanical condition of the periprosthetic bone due to implantation was least for the finned shell design. No significant deviation was observed at the bone region adjacent to the spikes and the fins. This study recommends the use of the finned design, particularly for weaker bone conditions. For stronger bones, the combined design may also be recommended for higher stability. The use of HC-UHMWPE liner was found to be better for convensional shell design. However, similar biomechanical response was captured in our FE analysis for both the liner materials in case of other shell designs. Overall, the study establishes the biomechanical response of periprosthetic bone in the acetabular with preclinically tested liner materials together with new shell design for different subject conditions.}, language = {en} } @article{TreutweinStegerLoescheletal., author = {Treutwein, Marius and Steger, Felix and L{\"o}schel, Rainer and K{\"o}lbl, Oliver and Dobler, Barbara}, title = {The influence of radiotherapy techniques on the plan quality and on the risk of secondary tumors in patients with pituitary adenoma}, series = {BMC cancer}, volume = {20}, journal = {BMC cancer}, publisher = {Springer}, doi = {10.1186/s12885-020-6535-y}, pages = {1 -- 13}, abstract = {BACKGROUND: This planning study compares different radiotherapy techniques for patients with pituitary adenoma, including flatness filter free mode (FFF), concerning plan quality and secondary malignancies for potentially young patients. The flatness filter has been described as main source of photon scatter. MATERIAL AND METHODS: Eleven patients with pituitary adenoma were included. An Elekta Synergy™ linac was used in the treatment planning system Oncentra® and for the measurements. 3D plans, IMRT, and VMAT plans and non-coplanar varieties were considered. The plan quality was evaluated regarding homogeneity, conformity, delivery time and dose to the organs at risk. The secondary malignancy risk was calculated from dose volume data and from measured dose to the periphery using different models for carcinoma and sarcoma risk. RESULTS: The homogeneity and conformity were nearly unchanged with and without flattening filter, neither was the delivery time found substantively different. VMAT plans were more homogenous, conformal and faster in delivery than IMRT plans. The secondary cancer risk was reduced with FFF both in the treated region and in the periphery. VMAT plans resulted in a higher secondary brain cancer risk than IMRT plans, but the risk for secondary peripheral cancer was reduced. Secondary sarcoma risk plays a minor role. No advantage was found for non-coplanar techniques. The FFF delivery times were not shortened due to additional monitor units needed and technical limitations. The risk for secondary brain cancer seems to depend on the irradiated volume. Secondary sarcoma risk is much smaller than carcinoma risk in accordance to the results of the atomic bomb survivors. The reduction of the peripheral dose and resulting secondary malignancy risk for FFF is statistically significant. However, it is negligible in comparison to the risk in the treated region. CONCLUSION: Treatments with FFF can reduce secondary malignancy risk while retaining similar quality as with flattening filter and should be preferred. VMAT plans show the best plan quality combined with lowest peripheral secondary malignancy risk, but highest level of second brain cancer risk. Taking this into account VMAT FFF seems the most advantageous technique for the treatment of pituitary adenomas with the given equipment.}, language = {en} } @article{AlvarezMoretObermeierPohletal., author = {Alvarez Moret, Judit and Obermeier, Tina and Pohl, Fabian and L{\"o}schel, Rainer and K{\"o}lbl, Oliver and Dobler, Barbara}, title = {Second cancer risk after radiation therapy of ependymoma using the flattening filter free irradiation mode of a linear accelerator}, series = {Journal of Applied Clinical Medical Physics}, volume = {19}, journal = {Journal of Applied Clinical Medical Physics}, number = {5}, publisher = {Wiley}, organization = {American Association of Physicists in Medicine}, doi = {10.1002/acm2.12438}, pages = {632 -- 639}, abstract = {Pediatric patients suffering from ependymoma are usually treated with cranial or craniospinal three-dimensional (3D) conformal radiotherapy (3DCRT). Intensity-modulated techniques spare dose to the surrounding tissue, but the risk for second malignancies may be increased due to the increase in low-dose volume. The aim of this study is to investigate if the flattening filter free (FFF) mode allows reducing the risk for second malignancies compared to the mode with flattening filter (FF) for intensity-modulated techniques and to 3DCRT. A reduction of the risk would be advantageous for treating pediatric ependymoma. 3DCRT was compared to intensity-modulated radiation therapy (IMRT) and volumetric-modulated arc therapy (VMAT) with and without flattening filter. Dose-volume histograms (DVHs) were compared to evaluate the plan quality and used to calculate the excess absolute risk (EAR) to develop second cancer in the brain. Dose verification was performed with a two-dimensional (2D) ionization chamber array and the out-of-field dose was measured with an ionization chamber to determine the EAR in peripheral organs. Delivery times were measured. Both VMAT and IMRT achieved similar plan quality in terms of dose sparing in the OAR and higher PTV coverage as compared to 3DCRT. Peripheral dose in low-dose region, which is proportional to the EAR in organs located in this region, for example, gonads, bladder, or bowel, could be significantly reduced using FFF. The lowest peripheral EAR and lowest delivery times were hereby achieved with VMATFFF . The EAR calculated based on DVH in the brain could not be reduced using FFF mode. VMATFFF improved the target coverage and homogeneity and kept the dose in the OAR similar compared to 3DCRT. In addition, delivery times were significantly reduced using VMATFFF . Therefore, for radiotherapy of ependymoma patients, VMATFFF may be considered advantageous for the combination of Elekta Synergy linac and Oncentra External Beam planning system used in this study.}, language = {en} } @article{GrabitzFriedmannGeppetal., author = {Grabitz, Peter and Friedmann, Zoe and Gepp, Sophie and Hess, Leonard U. and Specht, Lisa and Struck, Maja and Tragert, Sophie Kira and Walther, Tobias and Klemperer, David}, title = {Quantity and quality of conflict of interest policies at German medical schools}, series = {BMJ open}, volume = {10}, journal = {BMJ open}, number = {9}, publisher = {BMJ Publishing Group}, doi = {10.1136/bmjopen-2020-039782}, pages = {1 -- 8}, abstract = {OBJECTIVES: To assess the quantity and evaluate the quality of policies and curricula focusing on conflicts of interests (COI) at medical schools across Germany. DESIGN: Cross-sectional study, survey of medical schools, standardised web search. SETTING: Medical schools, Germany. PARTICIPANTS: 38 German medical schools. - INTERVENTIONS: We collected relevant COI policies, including teaching activities, by conducting a search of the websites of all 38 German medical schools using standardised keywords for COI policies and teaching. Further, we surveyed all medical schools' dean's offices. Finally, we adapted a scoring system for results we obtained with 13 categories based on prior similar studies. MAIN OUTCOMES AND MEASURES: Presence or absence of COI-related policies, including teaching activities at medical school. The secondary outcome was the achieved score on a scale from 0 to 26, with high scores representing restrictive policies and sufficient teaching activities. RESULTS: We identified relevant policies for one medical school via the web search. The response rate of the deans' survey was 16 of 38 (42.1\%). In total, we identified COI-related policies for 2 of 38 (5.3\%) German medical schools, yet no policy was sufficient to address all COI-related categories that were assessed in this study. The maximum score achieved was 12 of 26. 36 (94.7\%) schools scored 0. No medical school reported curricular teaching on COI. CONCLUSIONS: Our results indicate a low level of action by medical schools to protect students from undue commercial influence. No participating dean was aware of any curriculum or instruction on COI at the respective school and only two schools had policies in place. The German Medical Students Association and international counterparts have called for a stronger focus on COI in the classroom.
