FRANKFURT. They are young and well-trained – but a fourth of sport science students suffers from pain in combination with psychosocial stresses. This was revealed in a study that originated at Goethe University.

When active sport is at the centre of a profession or education, pain is often a constant companion – pain being defined in this case as physical and psychological symptoms. “One in three top athletes suffers significant pain," explains Dr. Johannes Fleckenstein, private lecturer at Goethe University. This is an issue that generally tends to be neglected, but he has made it the main focus of his classes.

This led to a master's thesis in which the author Anke Bumann looks predominantly at the situation of sport students. Bumann sent her questionnaire to the students of 89 sport sciences institutes in German-speaking regions. The response was impressive: 865 individuals took part, 664 completed the entire form, some adding very detailed answers in their own words.

The basis of the survey was the “German pain questionnaire" of the German Pain Society, supplemented by specific aspects such as athleticism, extent of training, self-efficacy and resilience. They were asked in which and how many regions of the body pain occurs, which injuries and other diagnoses are present, as well as psychological factors, alcohol consumption and sleep quality.

The study shows clearly: one in four of the presumably healthy young individuals suffers from pain and shows occurrence of what are known as biopsychosocial factors that can foster pain, in particular stress resulting from high performance pressure. More than half of those surveyed feel pain in two or more regions of the body – although most of them report a relatively high pain tolerance. Compared with others their age, sport students have more frequent depressions, anxiety and stress, while at the same time their self-compassion was significantly lower. On average, the students train five to seven hours a week and consume more painkillers (analgesics) and alcohol.  More than 60 percent report of sleep disorders. The findings are the same for all types of sports, with only the location of the pain being different. The lack of self-compassion for their own bodies and its limitations leads, however, to the condition becoming chronic and increasingly difficult to change.

The qualitative answers make it clear that the need is great: There was a frequent expression of happiness that attention was now being paid to the issue and for the opportunity to express one's problems. Fleckenstein hopes that if students confront and discuss this issue early it will help them deal with it more openly – without the fear of being branded as “wimps". In his opinion, teachers could also make a positive contribution by giving more consideration to the health of the candidates during practical exams. And when the sport scientists complete their studies and assume corresponding professional positions, they could gradually contribute to a change in attitudes.

“We have to finally stop trivialising the issue of pain in sports," demands Johannes Fleckenstein. It is alarming that pain disorders already occur in young and physically active students in this number. As professionalism increases, surmise the authors, the number of those affected also increases: “An enormously high performance is demanded, and there is a lot of money involved," says the sport medicine expert. For this reason, the study will now be continued with professional athletes.

FRANKFURT. On March 25, the “International Conference on Learning Analytics & Knowledge 2020" (LAK20) will be carried out from Frankfurt am Main as a complete online format. Responding rapidly to the spread of the coronavirus, the team of organisers has rescheduled and completely switched the event, joined by attendees across the world, to a virtual conference. Learning Analytics reflects the measurement and analysis of data from technology-based learning processes that are, for instance, gained in online courses or software tutorials. Learning is thus meant to be supported and optimised.

“Especially at an international level, Learning Analytics has been shown to have a relevant impact on education“, says Professor Dr. Hendrik Drachsler from DIPF | Leibniz Institute for Research and Information in Education and the Goethe University Frankfurt, who has held a leading role in organising the conference. DIPF and the University, together with Technical University (TU) Darmstadt, are hosting the LAK this year, which is operated by a German team for the first time. Drachsler explains that Learning Analytics is, for example, used to promote students in ongoing learning processes, or in setting up learner groups according to certain communication patterns which reveal insights into their collaborative needs. Drachsler is a computer scientist and Professor for Educational Technologies. He emphasizes the high relevance of data protection in the discipline: “The purpose of technology is solely to serve the learners' needs.“ To promote exchange in this field the team of organisers have done their utmost to ensure that the conference can take place even in the current situation.


Conference in a virtual space

The organisers have responded without delay and made sure that the conference, which was originally planned as a venue in Frankfurt am Main, can go online in a pioneering virtual format. Registered participants can, for example, dial into video conference rooms where live talks are broadcast from anywhere in the world. Moderated chats then offer an opportunity to pose and answer questions. Contributions are recorded, subject to contributors' consent. It is thus possible to flexibly watch the videos. Posters and applications are also presented in purely virtual settings. The programme spans long periods of the day, to accommodate for participants across seven time zones. The team is confident that the format with its spatial independence and flexible timing also offers incentives for future conferences.

Individuals who are interested should register by Tuesday, 24 March, 17 hrs CET to join LAK20. Please go here to register: https://lak20.solaresearch.org/registration

Thematically, the tenth LAK focuses on „shaping the future of the field". The conference is held once a year at alternating venues, under the auspices of the international network “Society for Learning Analytics Research“ (SoLAR). “Possible developmental lines will be traced for the next ten years and beyond. At the core, we will investigate ways of measuring learning and teaching and which insights can thus be gained, how they can be put to an optimal use and what needs to be considered regarding the different areas of implementation and scales of Learning Analytics", Dr. Christoph Rensing from the TU Darmstadt illustrates, a co-organiser of the LAK20.

Besides the general presentations, two keynotes are expected by international experts:

•  „Learning Analytics – A field on the verge of relevance?“
  Prof. Dr. Shane Dawson, Director of the Teaching Innovation Unit, Co-Director of the Centre for Change and Complexity in Learning and Professor of Learning Analytics at the University of South Australia

•  „Group Learning Analytics“
  Prof. Dr. Milena Tsvetkova, Assistant Professor at the Department of Methodology at the London School of Economics and Political Science

The team of LAK organisers is acting in a regional environment where the benefits and forms of implementing Learning Analytics are already being intensively discussed for the higher education area. Professor Drachsler and Dr. Rensing have thus initiated an innovation forum, as part of the project “Digitally supported teaching and learning in Hesse“, funded by the federal state of Hesse. Subject to this project, eleven universities in the state are designing innovative concepts for university teachers and students.

FRANKFURT. At least five million euros – this is the sum that Goethe University and the University Hospital want to collect to better meet the challenges of the Corona pandemic. Anyone can help: the money is to be raised through the donation platform betterplace.org and will go primarily toward researching the coronavirus, the urgent training of employees, and patient care at the University Hospital. Direct donations are also possible (please see link and donation account at the end of this press release).

The Johanna Quandt University Foundation made the start: non-bureaucratically, and within 24 hours, it provided a quarter million euros for the corona researcher Professor Sandra Ciesek and her team. With this money, the virologists from Goethe University and University Hospital want to advance their search for effective treatment. But this is only a beginning. The corona crisis requires a substantial degree of additional exertion – and therefore a substantial amount of additional funding.

“Our call goes out to everyone who wants to not just marvel at the incredible challenges, but to provide tangible help: donate to the Goethe-Corona fund. Every contribution is important and welcome," says University President Professor Birgitta Wolff, appealing to people's willingness to help. “If we all want to weather this crisis well and perhaps even emerge from it stronger than before, now is the time to set the course. If the city and university communities close ranks – not physically, of course – we can master even great challenges. This is precisely why the university was founded over 100 years ago," Wolff adds. As Stiftungsuniversität (university foundation under public law), Goethe University has the necessary leeway to also take unorthodox paths to enable financing, says Wolff. In the name of the University, the University Hospital, and the patients affected, she already expresses thanks to everyone who with their donation contributes to an improvement of the situation.

To master the crisis scientifically, clinically and organisationally, Goethe University and the Frankfurt University Hospital require additional personnel in the short term, and financial means. For this reason, the Goethe Corona Fund was established with the intention that it will quickly increase to at least five million euros – with the help of donations from the general public, foundations, and other private sponsors. Toward this end, a donation page was set up on the platform Betterplace; direct transfers are also possible, and both provide a donation receipt. First commitments have already been made from the circle of researchers: a professor has already  announced a donation of 40,000 euros.

“The growing pandemic entails a growing financial need in many areas: for example, we need money for specific equipment and experts, training for additional helpers in the crisis, and also to equip our medical personnel with protective clothing, goggles and face masks," says Professor Jürgen Graf, medical director of the University Hospital. In research, particular focus is placed on the patient-oriented research conducted by Professor Sandra Ciesek and her team: the goal is to find a vaccine and medical treatment for the aggressive virus, and to improve the diagnosis procedure. “With the aid of the additional funds we can emphatically expedite this research," explains virologist Ciesek. To do so, employees with biostatistical or biomedical training need to be hired in order to process and analyse the generated clinical data. In addition, additional equipment is urgently needed in virological and intensive care research and development in order to carry out experiments and studies more quickly and efficiently.

But in teaching as well, financial support is urgently needed: students should have the opportunity to participate in training and simulation classes to prepare them for the difficult situations in clinical daily routine. For this, additional medical simulation mannequins are required. “We are quick to reach the limits of our capacity in this area, although there is tremendous interest and commitment on the part of the students," says Professor Josef Pfeilschifter, Dean of the Faculty of Medicine at Goethe University. Teaching, education and training also depend on realistic simulations.

FRANKFURT. A particular neuronal circuit in the brains of bats controls their vocalisations. This was recently discovered by biologists at Goethe University Frankfurt. Based on the rhythm with which the circuit oscillated, the Frankfurt researchers were able to predict the kind of sounds the bats were about to make. These research results could contribute to a better understanding of human diseases in which language is impaired such as Parkinson's or Tourette syndrome.

Bats are famous for their sonar-based navigation. They use their extremely sensitive hearing for orientation, emitting ultrasound noises and receiving an image of their surroundings based on the echo. Seba's short-tailed bat (Carollia perspicillata), for example, finds the fruits that are its preferred food using this echolocation system. At the same time, bats also use their voices in a somewhat deeper frequency range to communicate with other members of their species. Seba's short-tailed bats employ a vocal range for this purpose that is otherwise only found among songbirds and humans. Like humans, they produce sound through the larynx.

Together with his team, neuroscientist Julio C. Hechavarria from the Institute for Cell Biology and Neuroscience at Goethe University investigated brain activity preceding vocalisation in Seba's short-tailed bats. The scientists were able to identify a group of nerve cells that create a circuitry from the frontal lobe to the corpus striatum in the interior of the brain. When this neural circuit fires off rhythmic signals, the bat emits a vocalisation about half a second later. The type of rhythm seemed to determine whether the bats were about to utter echolocation or communication vocalisations.

Since it is nearly impossible to make a prediction within half a second, the Frankfurt researchers trained a computer to test their hypothesis: The computer analysed the recorded sounds and the neural rhythm separately and attempted to make prognoses using the various rhythms. The result: in its predictions of echolocation versus communication vocalisations, the computer was correct about 80 percent of the time. Predictions were particularly accurate when considering signals from the frontal lobe, an area that in humans has been linked to action planning, among other functions.    

The Frankfurt scientists argue that the rhythms they observed in the bat brain are similar to neural rhythms often recorded from the human scalp, and concluded that brain rhythms could be linked to sound production in mammals in general.
Julio Hechavarria: “For over 50 years, bats have served as an animal model for studying how the brain processes auditory stimuli and how human language develops. For the first time, we were able to show how distant brain regions in bats communicate with each other during vocalization. At the same time, we know that the corresponding brain networks are impaired in individuals who, for example, stutter as a result of Parkinson's disease or emit involuntary noises due to Tourette syndrome. We therefore hope that by continuing to study vocal behaviour in bats, we can contribute to a better understanding of these human diseases."

The formation of gametes and the first cell divisions of the fertilized egg in mammals are prone to errors. Sometimes the wrong number of chromosomes is passed on to the offspring, or the first division leads to two nuclei instead of one in the two-cell embryo. In most cases, these errors result in miscarriages. Judith Reichmann has shown what leads to these errors in mouse embryos.

FRANKFURT am MAIN. Today, Dr. Judith Reichmann is receiving the €60,000 Paul Ehrlich and Ludwig Darmstaedter Prize for Young Researchers 2020. Dr. Reichmann, who works at the European Molecular Biology Laboratory (EMBL) in Heidelberg, researches the sources of chromosomal abnormalities in eggs and embryos of mice and their potential contribution to miscarriages. Mice synthesize a protein called Tex19.1, which maintains chromosome cohesion during the formation of oocytes and protects sperm cells from genetic damage. Without this protein, many mouse embryos have the wrong number of chromosomes and die after a few cell divisions. Errors also occur when the fertilized egg splits into two daughter cells. Reichmann was able to show that the paternal and maternal chromosome sets are not passed on via one but two mitotic spindles. As a result, the two sets of chromosomes sometimes drift apart during the cell division process so that the two-cell embryo ends up with two haploid cell nuclei instead of one diploid cell nucleus.

Reichmann discovered the dual spindle formation using light-sheet microscopy, which she developed further for this purpose. Mouse embryos do not tolerate continuous light exposure and therefore cannot be examined with a conventional microscope in high spatiotemporal resolution. This has precluded detailed live-imaging analyses in the past. In light-sheet microscopy, illumination occurs only in the plane that is actually being observed, while other parts of the embryo remain in the dark. "Judith Reichmann has shown how mice make sure that their offspring have the correct number of chromosomes, and only one cell nucleus. If this process fails, reproduction is compromised," the Scientific Council´s statement reads. "Reichmann's research may one day contribute to reducing the rate of miscarriages in women - provided that the sources of error identified in mice also apply to human reproduction".

Reichmann discovered that the Tex19.1 protein indirectly stabilizes the chromosomes during meiosis. This process ensures that the gametes enter fertilization with a single set of chromosomes, for without this process the number of chromosomes would double with each generation. In oocytes, stabilization of the chromosomes is needed because meiosis is interrupted for a long time and is only completed upon fertilization. When Tex19.1 is missing, the chromosomes drift apart in the egg. As a result, many embryos among the offspring do not inherit the correct number of chromosomes.

Reichmann's discovery of the dual spindles during the first cell division of the fertilized egg has toppled a textbook statement. Up to now, it had been assumed that the parental chromosomes merge in the fertilized egg and are distributed to the two daughter cells via a single spindle apparatus. Reichmann was able to show that the paternal and maternal chromosomes are grouped separately from each other in two spindles and are then distributed to the poles. Even in the nucleus of the two-cell embryo, maternal and paternal chromosomes initially remain in different hemispheres before they finally mix during subsequent cell divisions.

If Reichmann´s findings in mice also hold for human embryogenesis, and the human paternal and maternal chromosomes only merge in the two-cell embryo as well, a central assumption of the German Embryo Protection Act may have to be reconsidered. It states that human life begins when maternal and paternal chromosomes join; by this definition, the two-cell embryo rather than the zygote would take centre stage.

The Paul Ehrlich and Ludwig Darmstaedter Prize for Young Researchers has been awarded since 2006 in recognition of outstanding achievements in biomedical research.
