Cardiovascular diseases deaths are on the rise in South Africa

23 August 2022 | Story André Damons | Photo Supplied

Dr Walter Janse van Rensburg, Senior Lecturer in the Human Molecular Biology Unit, Department of Haematology and Cell Biology in the UFS School of Biomedical Sciences, says new research found that men of European descent over the age of 50 are the most vulnerable for the development of atherosclerosis.

A new study by researchers in the Human Molecular Biology Unit in the School of Biomedical Sciences at the University of the Free State (UFS) into atherosclerosis in the South African population found that men of European descent over the age of 50 are the most vulnerable for the development of atherosclerosis – the most common disorder associated with cardiovascular diseases (CVDs). Nearly half of men in this group had visible signs of atherosclerosis in the coronary arteries of the heart.

This was in contrast to the only roughly one-tenth of the African-descent males and females in the same age bracket. More than a third of women of European descent over 50 had visible atherosclerosis in their coronary arteries. One hypothesis regarding a possible explanation for this discrepancy is based on the theory that socioeconomic status may be a driving force behind CVD.

Risks factor for cardiovascular diseases

Dr Walter Janse van Rensburg, Senior Lecturer in the Human Molecular Biology Unit at the School of Biomedical Sciences, UFS, and principal researcher, says the study was conceptualised during 2020s COVID-19 pandemic, due to reports of excessive blood clots associated with both acute COVID-19 infection and some of the SARS-CoV2 vaccines. However, limited data existed in our region regarding the other underlying causes for blood clot formation, such as atherosclerotic plaque rupture. The data was collected during a couple of months in 2021. The data was collected out of more than 10,000 case files spanning 10 years. The study is still ongoing.

“Atherosclerosis remains a major risk factor for CVD, and thus, believed to be a good indicator of the CVD profile in a population, yet little is known on its prevalence in sub-Saharan African populations. We aimed to determine the prevalence of atherosclerosis in a diverse South African population as found in post-mortem investigations. A retrospective file audit was done on 10,240 forensic post-mortem reports done at a forensic pathology mortuary in South Africa, over 10 years,” writes Dr Janse van Rensburg in the Abstract of the research article.

According to him, cardiovascular diseases are reportedly the No 1 cause of mortality worldwide. According to the latest report from Stats SA, diseases of the circulatory system account for nearly a fifth of all deaths in South Africa.

“CVD is a multifactorial disorder, however, the presence of atherosclerosis (an inflammatory condition of artery walls) is the most common disorder associated with CVD. In order to assist in the prevention of the formation and progression of atherosclerosis, one can manage factors that have been associated with a higher risk for atherosclerosis, such as the use of tobacco, hypertension, elevated cholesterol, obesity, HIV infection and diabetes,” says Dr Janse van Rensburg.

Reasons behind different population’s mortality rate

It has been proposed, says Dr Janse van Rensburg, that socioeconomic status is possibly one of the essential roleplayers in CVD aetiology. The socioeconomic inequality in South Africa is well known, with an economic inequality Gini coefficient of 0.63 (the highest in the world). One study reported that in the Free State province, in the non-agricultural sector, the average household income for a European-descent household is roughly 4.35-times higher than the average African-descent household income.

“Therefore, it is postulated that wealthier people, in the South African context, historically people of European descent, have the means to afford and adopt lifestyles that contribute to the increased risk of lifestyle diseases such as obesity, hypercholesterolaemia and diabetes, which are associated with a higher risk to develop CVD.

“We postulate that CVD-related deaths are traditionally lower among South Africans of African descent compared to the other ethnic populations due to the historical socioeconomic discrepancy between people of African descent and other population groups in higher-income countries.”

The study also found that the prevalence of CVDs and the incidence of premature CVD-related deaths are steadily increasing in both rural and urban communities and across the socioeconomic spectrum. The theory of epidemiological transition says that in populations with improved living conditions and better access to healthcare, the proportion of deaths caused by infectious diseases will decrease, and the proportion of deaths due to more chronic “man-made” lifestyle-related diseases, such as CVD, will increase.

However, our population’s socioeconomic status is not the only driving force behind CVD. Therefore, we theorise there has been an upward trend in South Africa across all regions to improve the access to better food and better healthcare, consequently resulting in an increase in CVD-related morbidity and mortality statistics.

“For all population groups, males are more affected than females within their demographic group. This may also be possibly attributed to the socioeconomic status and access to the healthcare gender-gap differential in the country.”

Studies are vital in raising public awareness

Dr Janse van Rensburg says that studies such as this are vital in raising public awareness regarding disorders associated with the lifestyle choices people make. However, a multidisciplinary approach is needed to ultimately create a lasting impact.

“We hope that our findings will assist in identifying specific groups with a possible increased risk for CVD, and that we will inspire more focused research to identify potential high-risk behaviours within these groups that may eventually result in the enhancement of public health policies and awareness campaigns in our region.

“Recently, another article has been accepted for publication regarding the prevalence of excessive blood clots (thrombosis) as the underlying cause of death in our study cohort, further contributing to our understanding of the origins and contributory factors of CVDs in our region.”

State of our campuses

2017-10-30

STATEMENT OF THE RECTOR AND VICE-CHANCELLOR

The protests and disruptions of academic activities by students or groups of students on the Bloemfontein and Qwaqwa Campuses of the University of the Free State (UFS) since 18 October 2017 are taking place at a critical time in the academic calendar when students are writing the end-of-year examinations.

Not only does this place strain on students preparing for examinations, it also places strain on their families, and the entire university community.

I have spent most of my time since 18 October 2017 engaging with a large number of the university’s stakeholders, including concerned parents, staff, union representatives, alumni, the media, and various interest groups to share our plans and approach towards the protests and disruptions, and to ensure our stakeholders of the executive management’s commitment towards ensuring the stability of the campuses, and the uninterrupted completion of the 2017 academic year. Similar engagements by the executive management with the Student Representative Councils (SRCs) of the Bloemfontein and Qwaqwa Campuses have also taken place, and will continue.

During the past week, the disruption of academic activities, damage to and destroying of university property, criminal behaviour, and the violation of the rights of staff and students have occurred. Such behaviour is condemned in the strongest terms by the executive management, and directly contravenes the interdict granted to the UFS by the High Court of South Africa’s Free State Division on 22 February 2017. Although the university supports peaceful protests, I appeal to student leaders and the students who are in support of the protests, to continually prioritise the completion of the exams and the academic year. The executive management will keep on supporting peaceful protests of students about matters that are important to them, and obviously important to the university. However, we do not support the kind of disruptions and protests that transpired since 18 October 2017.

Last week, we were also made aware of alleged excessive use of force and assault of students by private security companies hired by the UFS at both the Bloemfontein and Qwaqwa Campuses. These allegations are currently being investigated. The executive management condemns in the strongest terms any misuse of force by private security.

The situation on the Bloemfontein and Qwaqwa Campuses is being closely monitored, and the necessary contingency plans remain in place to ensure the safety of staff and students, and to safeguard university property.

The executive management understands and shares the concerns of academic and support service staff about the completion of the academic year. We also understand the emotional anxiety that student protests and defiance generates among staff and students. I want to thank the university community for their support, as well as members of the institutional task team for their remarkable work under difficult and trying circumstances.

There is continuity between the student protests that started last year in October and what we are facing now. The unifying theme is students’ experience of financial exclusion from higher education. A contributing factor is the fact that President Jacob Zuma has not yet released the Heher Commission’s Report on the feasibility of fee-free higher education and training, which was handed to him at the end of August 2017.

The latest developments indicate that the President might release the report by the end of the coming week. This will hopefully provide more certainty on the issue of free higher education, and could therefore contribute to the stability on campuses at South African universities. The UFS, as a collective, will actively engage with the recommendations in the report once it is available.

The executive will continue to engage with the SRC, not only to strengthen the relationship between these bodies, but to constructively address various domestic challenges on our campuses.

UPDATE: 27 October 2017 at 15:03: Concession for students who experienced trauma on Friday 20 October 2017

As part of an agreement between the UFS Executive Management and the Bloemfontein Campus SRC on Monday 23 October 2017, it was agreed that there would be a process in place to allow students to write an additional exam if they experienced physical, emotional or psychological trauma relating to events that took place on the Bloemfontein and Qwaqwa Campuses on Friday 20 October 2017.

The names and student numbers of students were sent to management. In total, 1 236 student numbers were received, of which only 1 152 students were matched and qualified for an additional exam in place of the main examination that took place in the period 23 October to 28 October 2017.

Note: Only students with predicates qualify for the above concession.

Students will be notified via email by Wednesday 1 November 2017 if their applications have been successful. Should you have any enquiries regarding the notification or need to follow up on the process, you may contact the Student Academic Services Examination Division at addexam@ufs.ac.za. Lecturers will be notified via the Dean of the relevant faculty.

The students approved via this process, will also be eligible to apply for an ad hoc exam. This process will be managed by the Student Academic Services Examination Division.

Definitions:
· Main Examination: The first sitting of the final examination
· Additional Examination: The second sitting of the final examination. For the above students, this will be their first opportunity.
· Ad hoc Examination: A once-off concession for the above students, which allows them to apply for a second opportunity.
· Special Examination: A last opportunity given to students who have one module outstanding to complete their qualification. This examination is managed by the relevant ‘home’ of the outstanding module.

UPDATE: 26 October 2017 at 15:00: The exams on the campuses are continuing and no disruptions have been experienced since it started on Monday 23 October 2017.

A fire broke out on the Rag Farm of the University of the Free State’s (UFS) Bloemfontein Campus during the early hours of Thursday 26 October 2017, damaging the western side of the building. Arson is expected and the incident is being investigated by the South African Police Service (SAPS). On the same campus, two students were arrested in the early hours of Thursday morning for attempts to light a fire next to the Main Building. The incident is also being investigated by the SAPS.

On the Qwaqwa Campus, the situation is calm and no incidents were reported since yesterday morning.

The situation on the Bloemfontein and Qwaqwa Campuses is being closely monitored, and the necessary contingency plans remain in place to ensure the continuation of the exams, the safety of staff and students, and the safeguarding of university property.

UPDATE: 25 October 2017 at 14:26: Exams at the University of the Free State (UFS) are continuing today without disruptions on the campuses, after commencing on Monday 23 October 2017.

Early this morning, six students were arrested on the Qwaqwa Campus for contravening the Interdict. One of the two students who was injured and hospitalised the evening of 22 October 2017 on the Qwaqwa Campus during an incident between students, security officers, and members of the South African Police Service (SAPS) when a firearm was allegedly released, has been discharged. The second student is still in hospital and recovering well. The private security company involved in this incident has since been suspended and the incident is being investigated.

The necessary safety contingency plans remain in place on the campuses, and continued discussions/conversations between the executive management and the SRCs are taking place. Notices of intention to suspend will be issued to students who performed acts of a criminal nature or who violated the rights of staff and students.

UPDATE: 24 October 2017 at 13:36: Situation on the UFS Bloemfontein and Qwaqwa Campuses on 24 October 2017

The exams on the campuses of the University of the Free State (UFS) started yesterday (23 October 2017) without disruptions. The situation on the Bloemfontein and Qwaqwa Campuses is calm today and no disruptions have occurred at exam venues. The necessary safety contingency plans remain in place.

UPDATE: 23 October 2017 at 14:54: Agreement between the UFS executive management and the Bloemfontein Campus SRC on Monday 23 October 2017

During a meeting between the executive management of the University of the Free State (UFS) and the Bloemfontein Campus Student Representative Council (SRC) this morning, the following was agreed:

1.       Students who feel traumatised by events that took place on the Bloemfontein and Qwaqwa Campuses on Friday 20 October 2017 and do not think that they are fit to write exams, must provide their names and student numbers to the respective SRCs.

2.       In Bloemfontein, email should be sent to Asive Dlanjwa at DlanjwaA@ufs.ac.za; TyidaS@ufs.ac.za or submitted at Steve Biko House, Office 54. In Qwaqwa, email should be sent or submitted to the SRC President, Masopha Hlalele, at 2013037573@ufs4life.ac.za. These students will be excused from the exams taking place between 23 October and 28 October 2017, and will be given a chance to write additional exams. These exams will be regarded as the first opportunity.

3.       Students injured on the Bloemfontein Campus as a consequence of the events of Friday 20 October, should contact Dr WP Wahl from Student Affairs (to arrange for medical assistance).

4.       Students who wrote exams today (23 October 2017), but who feel that they have done so despite being traumatised and want to withdraw from the examination list, must indicate their names, student numbers, and the exam that they wrote. These students are also eligible for additional exams in relation to the exams set for the week of 23 October to 28 October.
5.       A window period of 48 hours (ending at 15:00 on Wednesday 25 October 2017) will be given to provide the names and details of students who experienced trauma to come forward for these arrangements to take place.

The following was also confirmed again during the meeting:

•         Students in Armentum and Beyers Naudé residences, which were singled out by the SRC as particularly affected by the events, would be offered counselling and medical assistance.

•         The 36 students jailed on Friday 20 October 2017, as well as those students residing in Armentum and Beyers Naudé who were traumatised or hurt by the events, will be starting exams a week later and will be given additional examinations for the modules they had to write during the week of 23 October to 28 October 2017.

•         Additional examination will be granted to all members of the SRC.

•         Any other student who was affected by Friday’s events and who is in need of counselling or medical attention, must indicate this to the SRC or the Office of the Dean of Students.

Please note the procedure for accessing counselling services: On the Bloemfontein Campus, students must go to the Student Counselling Offices, Health and Counselling Building (above Kovsie Health), to fill in the necessary forms and schedule emergency appointments.

UPDATE: 23 October 2017 at 07:28: Summary of events on the Bloemfontein and Qwaqwa Campuses since Wednesday 18 October 2017

Disruption of academic activities at the UFS started on the morning of Wednesday 18 October 2017 when a group of students blocked the main entrance to the Qwaqwa Campus and handed a memorandum to the campus management. Academic activities on the Qwaqwa Campus were interrupted, and resumed the next day. On the Bloemfontein Campus, disruption of some academic activities occurred after a meeting of students convened by the Student Representative Council (SRC). Members of the executive management subsequently met with the Bloemfontein Campus SRC, and a memorandum was handed to the executive management on 19 October 2017.

On the evening of 19 October 2017, seven students were arrested for arson on the Qwaqwa Campus, and four students were arrested on the Bloemfontein Campus on the morning of 20 October 2017 for contravening the Interdict. In the late afternoon of 20 October 2017, 36 students were arrested on the Bloemfontein Campus for contravening the Interdict. The arrest of this group of students occurred after the executive management responded to the memorandum of the SRC earlier in the day; the reply to the memorandum was rejected by the SRC and the students present.

Mindful of the Interdict and aware of the fact that these 36 students needed to prepare for exams, the university attempted to secure their release. This was not possible, given that the legal processing of these students by the South African Police Service (SAPS) had to continue. Students were finally released on bail on Sunday 22 October 2017 and will appear in court on Monday 23 October 2017.

Early on Saturday morning, the executive management met with the SRC and was made aware of incidents that took place at some residences, and the manner in which the private security company proceeded on Friday afternoon. The executive management explicitly stated that the approach taken by the security company was not in agreement with the UFS’s stand on student protest. At this meeting, it was agreed that the UFS would terminate its contract with the private security company and that it would initiate an independent external investigation into Friday’s events as soon as possible.

It was further agreed with the SRC that students in Armentum and Beyers Naudé, residences which were singled out by the SRC as particularly affected by the events, would be offered counselling and medical assistance.

It was finally agreed that the SRC, the 36 students jailed on Friday, as well as those students residing in Armentum and Beyers Naudé who were traumatised or hurt by the events, will be starting exams a week later and will be given special examinations for the modules they had to write during the week of 23 October 2017.

The students included in the categories indicated above, are the only students who had been granted special examinations. Any other student intending to request a special examination must follow the normal procedure.

Occurrences of fake news and miscommunication are taking place on social media – especially about the exams. The university’s official communication platforms (i.e. Newsflash, State of our campuses email, the website, Facebook, Twitter, Blackboard, SMS, and the ufs4life student email) are the only ones that carry official messages.
Exams start on all campuses on Monday 23 October 2017 at 08:00 and will continue as planned.

UPDATE: 22 October 2017 at 19:37: EXPLANATORY NOTE ON THE INTERDICT ISSUED BY THE FREE STATE HIGH COURT ON 22 FEBRUARY 2017

Since Wednesday 18 October 2017, disruptions and protests have occurred on and around the Bloemfontein and Qwaqwa Campuses of the University of the Free State (UFS), caused by students or groups of students.

On 22 February 2017, the High Court of South Africa, Free State Division, granted an Interdict against four respondents, of which the fourth respondent includes all individuals or legal persons acting in direct or indirect support of the activities to which this matter applies.

In terms of the Interdict, no registered student of the UFS, or legal persona may:

1.     Do anything which directly or indirectly obstructs, inhibits, prevents, disrupts, delays or interferes with the academic functioning of the UFS. This includes registration of students, any functions or events taking place at the UFS, tests, examinations and the processes related to academic activities, administrative services and normal student activities.
2.     Block, barricade or obstruct roads or entrances to the UFS. Similarly, roads on the UFS campus or entrances to buildings or venues on the UFS campus may not be blocked, obstructed or barricaded.
3.     Damage or destroy any property (moveable or immovable) on the UFS campus, irrespective of who the owners are.
4.     Molest, assault, threaten or intimidate UFS staff members, students, contractors and officials.
5.     Incite, taunt, instigate, prompt or encourage any other individuals or students to act in any way that violates this Interdict.

Please note that any student(s) who who contravenes the Interdict, will immediately be provisionally suspended.

The Sheriff of the Court and/or the South African Police Services are authorised to remove and expel from the UFS property and premises any student(s) who fails to comply with the provisions of the Interdict.

This Interdict is current and valid for all registered UFS students and legal persona operating at the university.

UPDATE: 22 October 2017 at 12:42: Exams will go ahead on the Bloemfontein and Qwaqwa Campuses on 23 October 2017
The exams will go ahead on the Bloemfontein and Qwaqwa Campuses on Monday 23 October 2017, as per the exam timetable. All academic and administrative activities are also continuing on both campuses tomorrow.

The situation on the two campuses is calm today, and no disruptions occurred during the course of last night.

The university crisis team – including members of the executive management and Protection Services – is on alert and has worked with the South African Police Service (SAPS) during the weekend to ensure stability on the two campuses during the exams. Security measures are in place for the exams and the situation on both campuses is monitored closely.

Occurrences of fake news and miscommunication are taking place on social media – especially about the exams. The university’s official communication platforms (i.e. Newsflash, State of our campuses email, the website, Facebook, Twitter, Blackboard, SMS, and the ufs4life student email) are the only ones that carry official messages.

Exams will proceed on the South Campus as scheduled.

UPDATE: 21 October 2017 at 12:45
The situation on the Bloemfontein and Qwaqwa Campuses of the University of the Free State (UFS) is calm today, and no disruptions occurred during the course of last night. Security measures are in place and the situation on both campuses is monitored closely.

Thirty six students were arrested on the Bloemfontein Campus yesterday at late afternoon, after a group of students clashed with members of the private security company and the South African Police Service (SAPS).

The executive management met with the Bloemfontein Campus Student Representative Council (SRC) this morning to discuss the arrest of students, as well as the disruptions of academic activities that happened on campus since Wednesday.

UPDATE: 20 October 2017 at 12:05: Situation on the Bloemfontein and Qwaqwa Campuses on 20 October 2017

Academic and administrative activities are continuing on the Bloemfontein and Qwaqwa Campuses today.

Last night, six students were arrested for arson on the Qwaqwa Campus. The South African Police Services (SAPS) and Campus Security were on the campus and are still monitoring the situation. On the Bloemfontein Campus, four students were arrested this morning for contravening the Interdict by causing disruptions at the Computer Labs and UFS Sasol Library. The SAPS is also deployed on the Bloemfontein Campus and are closely monitoring the situation, together with the university’s security team.

The executive management will meet with students on the Bloemfontein Campus at midday to provide feedback on the memorandum handed to them by the Student Representative Council (SRC) yesterday.

The safety of both staff and students remains a priority to the executive management. Staff and students on both campuses are requested to stay calm and to focus on the coming examinations and completion of the academic programme for the year. Measures are put in place to ensure that the exams will go ahead as planned. The university crisis team – including members of the executive management and Protection Services – is on alert and are working to stabilise the situation on the two campuses.

The continuation of the university’s academic programme is a serious matter to the executive management and the disruptive behaviour of some of our students will not be tolerated. Students who are identified while taking part in these incidents will be disciplined according to the university’s student disciplinary procedures.

Video recordings and/or photos of these incidents can be shared with Protection Services by contacting Noko Masalesa and Elise Saayman at masalesan@ufs.ac.za | saaymane@ufs.ac.za or +27 51 401 3436 | +27 51 401 9706.

Occurrences of fake news and miscommunication are taking place on social media – especially about the coming exams. The university’s official communication platforms (i.e. Newsflash, State of our campuses email, the website, Facebook, Twitter, Blackboard, SMS, and the ufs4life student email) are the only ones that carry official messages.

UPDATE: 19 October 2017 at 19:07: All academic activities on the UFS Bloemfontein and Qwaqwa Campuses will continue as normal on Friday 20 October 2017.

The necessary steps will be taken to ensure that outstanding classes and tests continue unhindered. Communication about the rescheduling of classes and/or tests affected by the disruptions on the Bloemfontein Campus will be sent via email tomorrow. Students on the Qwaqwa Campus must please check with the respective lecturers and/or information on Blackboard for details on rescheduled tests.

UPDATE: 19 October 2017 at 10:50: Situation on the Bloemfontein and Qwaqwa Campuses on 19 October 2017

During a meeting between the executive management of the University of the Free State (UFS) and the Student Representative Council (SRC) of the Bloemfontein Campus on 17 October 2017, a basic percentage point of 8% increase in tuition fees for 2018 was used as discussion point. Rumours on the social media of a different basic percentage point in relation to tuition fees for 2018 are untrue.

No decision has been made about the increase in tuition fees for 2018. Tuition-fee increases must be approved by the UFS Council, and therefore no decision about an increase in tuition fees for 2018 has been made yet.

Members of the executive management met with the Bloemfontein Campus SRC yesterday and it was agreed that a memorandum will be handed over today (midday); on the Qwaqwa Campus, a memorandum was handed to the campus management yesterday.

The Rector and Vice-Chancellor, Prof Francis Petersen, has subsequently been in discussion with the President of the Bloemfontein Campus Student Representative Council, Asive Dlanjwa, regarding yesterday’s disruption of academic activities on the campus. The campus management of the Qwaqwa Campus are in a similar conversation with the campus SRC, and discussions will continue today.

The situation on the Bloemfontein Campus remains under control and is being closely monitored, with academic activities on the campus continuing as normal today. The situation on the Qwaqwa Campus is calm today and academic activities, including tests, are continuing as scheduled. Staff and students on both campuses are requested to stay calm and to focus on the completion of the academic programme for the year.
