Opinion article by Angela Vorster, Clinical Psychologist at the School for Clinical Medicine, University of the Free State.
Twenty-three people will die from suicide today in South Africa. Another 460 South Africans will try to end their lives today. They are from different cultural groups, different income groups, attained different levels of education, speak different languages, range in age from childhood through to elderly, have different genders and sexual orientations. These people have very little in common except that their lives all ended due to the final symptom of an illness. People who experience thoughts of ending their lives describe this mental space as feeling grey. Their thoughts tend to keep returning to the futility of being alive, what a burden they are to those around them, how nothing will ever get better and that nobody can help them. They tend to experience feelings of worthlessness, self-hatred, guilt, hopelessness, immense sadness and despair. Their suffering and emotional pain are excruciating. Nothing is enjoyable anymore. There is nothing to look forward to. Everything is difficult, boring, scary or meaningless. Inwardly they are drowning. But very often they smile, do their job and pass their exams, go on dates and vacations, make plans for the weekend and check up on their loved ones. They look happy in their photos. And when someone asks them if they are okay they say yes. Because they don’t feel like they deserve to feel better. They don’t want to be a bother. They might not call a helpline or make an appointment to see a psychologist or go to their GP for anti-depressants. Because they just don’t have the energy. It’s exhausting pretending to be fine all day. The one thought that brings relief is that they can end this pain. And one day they do. And their colleagues, friends and family are left reeling with shock and disbelief. How could this have happened? How could they have missed the signs? What should they have done differently to prevent this? 

The causes are as complex and varied

This is the purpose of World Suicide Prevention Day which takes place internationally each year on 10 September and through which the International Association for Suicide Prevention endeavours to increase awareness of suicidality, as well as to fight the stigma associated with suicide. Wanting to die can occur along with many other symptoms and disorders including, but not limited to, depression, post-traumatic stress disorder, bipolar disorder, psychotic disorders, personality disorders and substance dependence or abuse disorders. The causes are as complex and varied as the manner in which suicidality may present. It is dangerous to regard only certain signs and symptoms as indicative of suicide risk, because we know that suicide can be extremely unpredictable. There is no way to tell if someone is a suicide risk based purely on their behaviour. However there are certain factors which may indicate an increased risk for self-harm. These include, but are not limited to, having previously tried to end their life, having a psychiatric illness, being seriously ill or having chronic pain or the misuse of substances. Experiencing legal, relationship, financial or academic stressors may increase suicide risk, as well as having access to lethal means to end their life along with being unable to access mental health care. 

So what can you do if you think someone may be at risk of self-harm? Say something. Talk to them. Tell them what you are worried about and give them the space to express how they feel without judgment or condemnation. Reach out to their support system and share your concerns with them. Encourage the suicidal person to make contact with a health care professional – this can be a psychologist, GP, psychiatrist, social worker, psychiatric nurse, counsellor or a suicide prevention help line. Other important members of our community who provide a great deal of assistance to suicidal people and their families include religious and spiritual leaders, teachers, support groups and employee assistance programmes. There are actually so many ways and places to receive health care and support; however the most significant barrier to making use of these resources is sustained by the stigma associated with suicide and mental illness. In our culture of toxic positivity where our photos are touched up, our statuses updated and our successes plastered on various social media platforms, the authentic act of acknowledging when we feel defeated, unhappy or like a failure has become a rarity. The more real, honest and vulnerable we can be about our ‘undesirable’ emotions and experiences, the more space we create for those around us to do the same. When we normalise not being okay at all times, we give ourselves and others permission to speak up when we need help. And this is our greatest weapon against suicide – authentic connection.

What suicide is not

We’ve explored what it may feel like to be suicidal, now let’s focus on what suicide is not. Suicide is not a moral failing. It is not because the person was weak or selfish, it is not because their family was dysfunctional or their faith not strong enough. Suicide is the final symptom of mental illness – and every single person is vulnerable to experiencing suicidal thoughts. Each one of us will be affected by suicide during the duration of our lives, either directly or indirectly. This is irrespective of how successful you are, how supportive your family is or how strong your religious convictions are. Dying by suicide is not a shame. It is not a failure. It is no different to a patient dying from any other disease. And just like any other illness there are symptoms we can look out for and treatments and medications that can assist in recovery. 

Please think before you speak about someone who died due to suicide. I guarantee that at least one person in the conversation has suffered the pain of losing someone in this way. But you probably wouldn’t even know, because stigma silences. Stigma disconnects and alienates those who need support the most. Our words have the power to shame and silence, or to empower and encourage connection, which is lifesaving. Treat each conversation as though there may be someone present who is having suicidal thoughts or is working through the loss of someone they love due to suicide. Often we want to reach out and support families affected by suicide, but don’t because we are afraid of offending, or upsetting or because we ourselves are so uncomfortable with mental illness. But all these survivors of suicide need from you is your calm, empathetic, kind presence, a safe space to express difficult and messy emotions. Without being blamed or shunned or shamed. Support suicide survivors as though a terrible illness took the life of their loved-one. Because that is exactly what happened. 

On 10 September this year I encourage you to light a candle and place it in your windowsill around 8pm wherever you are. This is in remembrance of those lost to mental illness and to show your support to those they left behind. In the words of the International Association of Suicide Prevention: “By encouraging understanding, reaching in and sharing experiences, we want to give people the confidence to take action. To prevent suicide requires us to become a beacon of light to those in pain. You can be the light.”

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
