Koç University Researchers Are at Work

It has been more than one and a half months since the first case of COVID-19 was reported in our country. Even though we are learning and experiencing new things about both the virus that causes the disease and the disease itself every day, this did not get in the way of scientists to roll up their sleeves and go into battle.

Right now, perhaps thousands of studies are being conducted at many universities and research institutions all over the world to find effective solutions for COVID-19. In Turkey, there are countless studies that are being carried out under the leadership of competent organizations, namely The Ministry of Health and TÜBİTAK (The Scientific and Technological Research Council of Turkey) and there is intense work within universities on matters such as disease diagnosis, treatment, determining how the disease spreads, management of the pandemic, development of patient tracking systems, vaccination, medication and equipment production, and organizing support systems.

Koç University is also one of the institutions that embraces the challenge and works on the issue vigorously with its departmental prowess. There are currently 39 multifaceted projects managed within the university most of which are interdisciplinary and could even be considered as supra-disciplinary. Some of these projects focus on diagnosis and treatment while others zero in on follow-up and even support; all projects are carried out with utmost scrutiny.

The first step in combating disease is diagnosis. If you have an accurate diagnostic system, the primary line of defence against an outbreak includes fast and effective detection of infected individuals and appropriate interventions. One of the projects that is managed at Koç University focuses on developing a novel diagnostic kit and measuring device based on SERS technique which will be able to detect whether COVID-19 is present in a patient’s nasal droplets with high sensitivity and fast response time.

Moreover, one of the most popular topics of the discussion revolves around whether or not the microdroplets in the air carry coronavirus and whether or not there is a risk of infection due to these droplets. Imaging studies which target microdroplets and aerosols in the air, as well as the development of a PCR system which collects samples from the air, are among the projects that are underway.

The next step is the treatment process. Medication is surely the most powerful instrument in this process. While everyone is waiting for the “magic pill” nowadays, scientists are at laboratories testing perhaps millions of molecules. Another study that is carried out at Koç University is based on observations of strong inflammatory response due to intense cytokine storms which can be triggered by various factors such as infection and medication use among patients who suffer more severe disease despite ventilation. There is also a project that is based on manufacturing anakinra and biosimilars since treating these patients with anti-inflammatory biologics like tocilizumab and anakinra has shown positive results. Yet in another drug research project, a study to identify drugs that block the spread of the virus in epithelial cells of the lungs was carried out. In the study, drugs that have the least side effects were identified among those that are currently used to treat other diseases and that have been approved by the FDA to inhibit the enzymes that are essential to the life cycle of SARS-CoV-2019; drugs that can block the spread were identified using a computer simulation.

Surely, manufacturing certain medical devices to help patients persevere through the process with ease is as vital as developing drugs that compensate for the devastating impact of the virus.

Again, in addition to the ventilators that are manufactured in laboratories at Koç University, a portable breathing support system, the ECMO machine, and a sensitive lung simulator are among the systems that are developed; robotic automation of PCR systems is also under development.

In addition, follow-ups are also as important as treatment. The goal is to develop a system for monitoring infected patients who are quarantined at home by health teams, optimizing the order, time, and route of team visits to facilitate systematic follow-up and response as well as developing cost-effective software/hardware based on Bluetooth and Wi-Fi signaling techniques, especially for high-risk older adults. Patient follow-ups, maintenance of social distancing, and application of telehealth are within the scope of the project.

It is also crucial to consider the big picture in terms of diseases like COVID-19 which impacts the whole world and does not discriminate; investigation of the discrepancy between death rates in other countries is the subject of a project which will give us important clues about fighting the disease. Also, projects focused on the examination of thorax CT images by using artificial intelligence or those that are about dynamic modelling of the spread of the virus offer important insights into the preventative steps that can be taken both in the present and in the future. In addition, there are projects underway to support clinicians who are treating patients in more complicated conditions; projects that investigate the psychological impact of the pandemic on radiotherapy patients or the role of Autism Spectrum Disorder (ASD) in understanding the COVID-19 infection and projects that investigate the challenges that are brought on by the virus in ASD patients’ continuation of treatment show that dealing with COVID-19 will require more effort than simply fighting off an infection. The goal of these projects is to come up with solutions to support patients and clinicians who are fighting diseases besides COVID-19.

These are just a handful of the studies that are carried out at Koç University, below, you can find the complete list of the projects that are undertaken by researchers who have mobilized together and put tireless effort into research during this process.

We are certain that all of these studies will be worth the effort and under the guidance of science, humanity will come out of this process stronger than ever.

 Drug Development

*Producing a Drug to Treat Cytokine Storm Caused by COVID-19-Induced Pneumonia

In severe COVID-19 patients, the disease induces a cytokine storm, followed by the severe inflammatory response, even when the patients are placed on ventilators. When treated with anti-inflammatory drugs such as anakinra and tocilizumab, some of the severe COVID-19 patients responded well and were saved. The goal of our project consortium is to produce anakinra and its bioequivalent derivatives.

*Prototype Design of The Pressure Measurement System of Tofas R&D Ventilator Which Went Into Mass Production

In cooperation with the Tofaş R&D team, we provided a prototype of the measuring system and pressure transducers, which is a critical component of this system that is now in mass production. This measurement system was previously developed for device projects at Koç University and have already been tested in the patients. For this reason, this measurement system, which is currently difficult to obtain, was provided quickly.

*Prototype Design and Production of Intensive Care Unit Systems That Allow Remote Patient Management And Improved Testing Chambers

With the help of our intensive care, anesthesiologist and cardiac surgeon colleagues, a biomedical engineering/clinician collaboration network has been established in order to identify the current needs of COVID-19 response. Current studies are carried out to develop robotic systems and patient care units for remote patient monitoring. We applied for funding from Istanbul Development Agency for project support.

*Development of Accurate In Vitro Lung Physiology Simulators at The Bench Top

Although there are various ventilator design and production campaigns ongoing worldwide, there is a shortage of accurate lung simulators, which can replicate both the disease and healthy physiological response. These systems enable validation and improve the safety of ventilators before they are used in COVID-19 patients. Through our previous experience with in vitro cardiovascular system simulators, we started developing physiological lung mock-up systems. To our knowledge, there are only two simulators in Istanbul which are now idle due to lack of trained personnel. These simulators are important for both testing devices during the prototype design phase and also training new doctors recruited for COVID-19 patents.

*Prototype Production of Extracorporeal Membrane Oxygenator Components That are Used in Most Severe COVID-19 Patients

Extracorporeal membrane oxygenator (ECMO), which is a critical device for the most severe COVID-19 patients at intensive care units. Compared to the artificial ventilators, ECMO is a much more complex blood-wetted device that requires technological expertise for its design and production. Since 2019 with the support of TÜBİTAK, we are working on to develop ECMO oxygenators and their cannulas.

*Psychological Effects of COVID-19 Pandemia on Radiation Oncologists  

Morbidity and mortality of COVID-19 infection might be high, and cancer patients are under a high risk group to face detrimental infection complications. Treating this high risk group, including possibly asymptomatic infected patients as well as patients with COVID-19 diagnosis at admission or during treatment, increases the risk to be infected in healthcare providers, especially the physicians in close contact with the patients. This study is aiming to reveal the details of this psychological burden in radiation oncologists to propose a related action plan.

*Effect of COVID-19 Pandemia on Clinical Practice in Radiation Oncology 

Morbidity and mortality of COVID-19 infection might be high, and cancer patients are under a high-risk group to face detrimental infection complications. The radiation oncologists have to decide which indications could require emergent radiotherapy, as well as cancelled or delayed/postponed radiotherapy approach, in addition to how to start or complete the ongoing treatments appropriately, in these pandemic environments without any level I evidence guideline to secure the decisions. This study is aiming to reveal the details of changes and modifications made in clinical practice including safety and treatment schemes in radiation oncology clinics to propose a related action plan.

Prof. Uğur Selek (Radiation Oncology, School Of Medicine)

*Psychological Effects of COVID-19 Pandemia on Patients Under Treatment in Radiation Oncology 

Morbidity and mortality of COVID-19 infection might be high in cancer patients. Therefore, patients under treatment for their cancer feel increased psychological pressure whether to continue their treatment or to give a break, despite giving all medical information. This study is aiming to reveal the details of this psychological burden to propose a related action plan.

Prof. Yasemin Bölükbaşı (Radiation Oncology, School Of Medicine)

*Could PSA be a Prognostic Marker in Men with COVID-19?

Prof. Tarık Esen (Urology, School Of Medicine)

*The Role of Autism Spectrum Disorder (ASD) in Understanding COVID-19 Infection and the Problems Caused by COVID-19 Infection in the Treatment of Patients with ASD

When individuals diagnosed with ASD are isolated at home during the COVID-19 process, there will be a significant increase in almost all problematic behavior areas (such as excessive mobility, stereotypical behavior, self-harming behavior). It is anticipated that obsessive and repetitive behaviors will increase at the highest rate among problem behavior sub-fields. It is predicted that there will be a decline in some social communication areas that individuals diagnosed with ASD gain through special education. An increase in the sensory sensitivity of ASD children is expected in this period. Also, ASD children’s sleep problems are expected to increase in this period. There is a positive correlation between primary caregiver (mother) anxiety and the child’s behavioral problems.
