Medical students in the Faculty of Health Sciences at the UFS will now be able to learn how to perform procedures such as the precise location of a vein for intravenous lines and for diagnostic procedures such as detecting abnormalities in pregnancies, identifying gallstones, and diagnosing trauma-related injuries with ease.  This will be made possible by the placement of a one-of-a-kind ultrasound machine – putting them on par with cutting-edge global medical technology.

A first ever in the medical curriculum of undergraduate students at the UFS

The state-of-the-art, compact HS70A Samsung ultrasound system to the value of R1,4 million was unveiled in the Faculty of Health Sciences’ Clinical Simulation and Skills Unit on 19 November. A first ever in the medical curriculum of undergraduate students at the UFS, it is set to revolutionise the delivery of health-care education in the faculty, said Prof Lomby Odendaal, Teaching and Learning Coordinator for undergraduate anaesthesiology training in the Department of Anaesthesiology.

The ultrasound system was donated by SSEM Mthembu Medical and Samsung Korea.
Prof Odendaal said for the first time in the history of the undergraduate MB ChB curriculum, the ultrasound will be available to medical students from their third year. Students have never had the opportunity to be trained in using ultrasound this early in their careers.

Improved clinical training experience of students

Ultrasound is a diagnostic medical tool that uses sound waves to produce images of internal structures of the body. Prof Odendaal said ultrasound is important to determine pathology and diseases in the body and to provide point-of-care ultrasound. Having the ultrasound in the unit will transform the clinical training experience of students, training them to provide better treatment and medical care, even in constrained environments, to improve patient care.

“There is almost no structure in the body that cannot be examined using ultrasound. It makes the delivery of healthcare more effective. If you make a better diagnosis, the treatment and care will be much better. Ultrasound is so important lately that if you don’t do it, you will be left behind. That’s why we decided to bring this to the students. We can’t miss out on teaching our students about ultrasound, because we want them to be familiar with it by the time they finish their medical degree, so that, even if they go to smaller hospitals, they will be able to spread diagnostic care to the periphery,” Prof Odendaal said.

Streamlined workflow for patient care

“The cutting-edge technology and rich image quality of the ultrasound will deliver top-notch diagnoses to suit the diverse departments within the faculty,” said Chase Hutchinson, National Product Manager at SSEM Mthembu Medical. It comes with various pre-set models to cater for different needs and applications, allowing streamlined workflow for higher efficiency and patient care.

According to Prof Mathys Labuschagne, the Head of the Clinical Simulation and Skills Unit, ultrasound training will improve the quality of doctors graduating in the faculty. “We are really excited about this. You can diagnose many conditions using ultrasound and deliver point-of-care ultrasound; this will become a natural part of students’ training and clinical practice in future.”

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
