Two final-year MBChB students show how it is done when they donated blood earlier this year.

Bachelor of Medicine and Bachelor of Surgery (MBChB) staff and students in the Faculty of Health Sciences have challenged other departments in the faculty as well as other faculties and departments at the University of the Free State (UFS) to see whose staff and students will donate the most blood!

Mrs Angela Vorster, UFS Clinical Psychologist, says the South African National Blood Services (SANBS) has been appealing for increased blood donations since the onset of the COVID-19 pandemic last year. In order to provide support, the School of Clinical Medicine at the UFS held a virtual blood donation challenge in 2020, to encourage students to participate in altruistic behaviour and to enable the pre-clinical platform year groups to also feel like they are providing essential medical assistance.

“This was hugely successful and consequently we decided to include a blood donation challenge in our annual Mental Health Awareness programme. The benefits of donating blood are not only of a physiological nature (e.g. it assists in reducing iron levels and helps to control high blood pressure etc.) but means you are giving something of yourself. It will definitely save at least one life, perhaps more, and is incredibly beneficial in enhancing feelings of self-worth and personal meaning,” says Vorster.

The Faculty of Health Sciences invited the SANBS to UFS this week to provide all students and staff with the opportunity to donate blood at their place of work and study. So Have a Heart and take a few minutes to relax with a cookie and cool drink while your heart does the work of blood donation for you.

Details are as follows:

When: 18 and 19 February

Afromontane Research Unit makes climate change inroads

The Afromontane Research Unit (ARU) has recently made inroads in climate-change research. This has been achieved through work published by Professor Geofrey Mukwada and Professor Desmond Manatsa, whose research could make it possible to predict El Nino Southern Oscillation (ENSO) several months before its occurrence. 

Professor Manatsa is an ARU postdoctoral fellow currently collaborating with Professor Mukwada on an ongoing climate-change research project. The two experts noted that ENSO is one of the most important climate phenomena on earth, due to its ability to change the global atmospheric circulation, which in turn, influences temperature and precipitation across the world.

Climate change scientific breakthrough

“This is a tremendous breakthrough, because humanity as a whole has been looking for answers regarding the origins of climate-related hazards which are worsening, yet becoming more frequent and difficult to predict. In some cases, floods and droughts occur in the same season, and within the same geographical area. These extreme climate events are becoming more frequent, often leading to loss of life and threatening national economies and livelihoods,” said Professor Mukwada, coordinator of the ARU sub-theme on Living and Doing Business In Afromontane Environments.

During an interview with the Southern Times, Professor Manatsa revealed that the El Nino Southern Oscillation (ENSO) is initiated and sustained in the tropical Pacific, a fact that has eluded climate scientists for years. “It was an unresolved puzzle which limited the successful prediction of ENSO events with reasonable lead time. Climate scientists were only able to know with some degree of certainty that the event would occur once it had started, just a few months before its impacts were felt,” Professor Manatsa said.

Prof Manatsa is upbeat that a lot of headway has now been made towards unravelling the mystery of ENSO’s origin. “The necessity of the inclusion of the solar energy changes due to ozone alterations in the upper atmosphere should significantly impact on the realistic version of ENSO in climate models. This in turn should not only provide more accurate ENSO forecasts for the region, but a longer lead time for users to prepare for the event,” he said.

ENSO is a climate phenomenon based in the tropical Pacific Ocean. Its events bring good rains and even floods over most parts of the world in some years and droughts in others, depending on whether the phenomenon is in a warm or cold phase. The warm phase is referred to as El Nino, when the waters over the tropical east Pacific are heated up, but when cooled, it is termed La Nina. La Nina was responsible for the favourable rains over much of Southern Africa, including Zimbabwe, during the 2016/17 rainfall season. The El Nino occurrence a year before had devastating drought effects that was characterised by scorching heat and widespread water shortages. This work was published in a high-profile journal, Nature Scientific Reports

ARU is a flagship inter- and trans-disciplinary research programme focusing on the under-researched area of montane communities. It was launched in June 2015 and is based on the Qwaqwa Campus.
