Research focus: Circulation and vascular research

PI: Nandu Goswami

Focus: Research interests include the effects of various disorders - on the one hand in healthy humans, such as aging, space travel, prolonged bed rest or exercise, and on the other hand in diseases, such as lymphedema, preeclampsia, HIV, COVID-19, dyslipidemia and diabetes mellitus - on the cardiovascular system. Another area of interest is the vascular system and how it is affected by chronic stimuli. The broad methodological spectrum used here includes noninvasive measurements of endothelial and vascular function as well as blood biomarkers related to endothelial function and blood coagulation in healthy subjects. Our studies are based on data collection in healthy volunteers as well as on patient data and different disease models.

Network: We collaborate closely with various partners within Med Uni Graz. These include research teams from the Division of Physiological Chemistry (Gerhard Cvirn: Coagulation; Karl Öttl: Plasma Proteins), the Division of Pharmacology (Gunter Marsche: Lipid Oxidation), the Diagnostic & Research Institute for Hygiene, Microbiology and Environmental Medicine (Harald Kessler: HIV and COVID-19), the Department of Internal Medicine (Harald Sourij: Diabetology; Regina Roller-Wirnsberger: Geriatrics; Martin Stradner: Rheumatology), the Department of Obstetrics and Gynecology (Mila Cervar-Zivkovic: Preeclampsia), the Department of Medical Psychology and Psychotherapy (Christian Fazekas: Resilience), and the Department of Psychiatry (Sabrina Mörkl: Depression).

Projects

SARS-CoV-2 infection in HIV-positive patients with or without antiretroviral therapy in sub-Saharan Africa: Cardiometabolic risk, Thrombosis and Vascular function in sub-Saharan Africa (ENDOCOVID)

  • The aim of this novel study is to assess the number of SARS-CoV-2 infections in people living with HIV in two sub-Saharan countries (South Africa and Nigeria). Furthermore, ENDOCOVID aims to estimate the severity of covid-19 disease and to evaluate the effects of covid-19 on vascular function and coagulation during infection and recovery in HIV-positive patients with and without antiretroviral therapy (ART). Cardiometabolic risk, thrombosis risk, and markers of vascular function will be collected.

Health & Academic Performance with Happy Children (HAPHC)

  • Over the past decades, there has been a huge increase in inactivity and obesity among children and adolescents. Increased physical activity and a healthy diet can help to curb this development. The aim of this project is to explore how physical activity, actively incorporated into the classroom, affects school children. The experience gained in Norway (HOPP project) and the knowledge that has already been established will be continued and extended to Europe.

Projects funded by Land Steiermark: "Young children in the digital world" and "Analysis of stress levels during the Corona crisis using cortisol measurements from hair strands"

  • "Young children in the digital world" investigates the influence of the use of interactive, digital media on the health and development of toddlers, how different offers differ in their effect as well as the influence of the duration and type of media use. "Analysis of stress levels during the Corona crisis using cortisol measurements from hair strands" explores how the exposure to COVID-19 affects the stress levels of different population groups, determined by stress hormone measurements from hair strands as well as questionnaires.
  • Duration: 2018-2021 und 2020-2021

ESA projects (bedrest, dry immersion and artificial gravity)

  • Four different ESA-funded projects are investigating how microgravity (bedrest and dry-immersion studies) and hypergravity (artificial gravity (AG)) affect different physiological systems. On the one hand, the effect on venous blood flow, viscosity and inflammatory parameters as well as molecular mechanisms of coagulation are investigated. On the other hand, how hemodynamics and blood flow in different regions are affected by AG exposure (an individual orthostatic threshold is applied) is explored.

The relationship between polymorphisms of candidate genes and primary lymphedema

  • Since lymphedema patients show significant (subclinical) measurements of cardiovascular dysfunction - related to microvascular dysfunction - before, during and after decongestive therapy, measurements of endothelial and coagulation parameters will be performed. The project will also investigate the relationship between possible gene polymorphisms and these parameters. The influence of functional polymorphisms of candidate genes on the dynamics of cardiovascular responses (e.g. I/D-ACE polymorphism or polymorphisms of the angiotensinogen gene) will be evaluated.
