If you are reading this you may be interested in better understanding why there is a need for a World Suicide Prevention Day each year on 10 September. For some it may seem morbid, while for others it is just another awareness initiative. But for too many, suicide is personal. You may have lost someone you love in this manner. Or you yourself may be struggling with thoughts of ending your life. If you fall into the latter group you may want to skip over to the very last paragraph, because I know your attention may be waning and your energy may be low. Everybody else, please join me in better understanding the need for awareness of thoughts of self-harm and attempts at ending one’s life.

Mental illness can be fatal 

In most instances dying by ‘suicide’ is more accurately described as dying from a psychiatric disease. Mental illness can be fatal if left untreated and we need only refer to suicide-related statistics to realise the magnitude of this plague in South Africa. The World Health Organisation indicated that South Africa is ranked 10th on the list of international countries with the highest suicide rates, while The South African Depression and AFnxiety Group (Sadag) reports 23 deaths by suicide per day. For each person who dies by suicide in our country; 10 others attempt to end their lives. Up to nine out of 10 people who die by suicide in South Africa had a mental health disease such as depression at the time of their death. If we take a look at these facts, it becomes almost absurd that we still regard mental illness and thoughts of self-harm and the act of causing self-death, as shameful and abnormal. But that is still very much how mental illness and particularly suicidality are viewed in our communities. Perhaps if we are able to really understand what it feels like to feel so terribly sad, empty, hopeless, worthless and guilty that you would rather end your life than suffer through another hour; perhaps then we would be able to create safe spaces for those who feel suicidal to express how they feel. It is only through connection and communication that we can provide the right support at the right time in order to save lives.

The black dog

There are many descriptions of what it feels like to be so ill that death seems the only cure and these vary across cultures and countries. The Black Dog Institute in Australia derived its name from the description of depression as feeling as though a menacing dark dog-like creature is following you around and no matter how hard you try, you just can’t shake it. Winston Churchill used this metaphor to describe times when he felt melancholic, demotivated and down. Now I love dogs, so I imagine this particular type of canine as being almost monstrous, not leaving you alone, but also not giving you anything. Instead of the loyalty and companionship and protection that our pet dogs give us, this dog demands constant feeding, does not allow you any freedom and prevents you from making contact with other people. The moment you start to reach out to someone, this black dog starts growling in the background and you give up or scare them away with your dark mood. And the black beast has you all to himself once again. This type of depression sucks your energy and your motivation. It makes you irritable and tired and isolated. Difficult to like.

Another metaphor for depression is ‘feeling blue’, one which we use so frequently that we have perhaps not stopped to consider where it originates. There are many theories, and all of them quite bleak. One is that the description derives from the human body that turns blue after death; another that ships used to fly blue flags if their captain had perished at sea, and yet another, that Zeus, the Greek God of the sky and thunder, would make it rain when he was sad. Have you noticed how flippantly people comment on ‘the baby blues’ as though this were something almost endearing and expected that is associated with becoming a mother. This while the stark reality of post-natal depression has been highlighted in the recent trial of Dr Lauren Dickason in New Zealand. I cannot comment on the legal aspects related to her case, but what I found jarring was the number of times that she told the people around her that she wanted to die or that she wanted to harm her children. I have worked with many women diagnosed with post-partum depression who describe feeling as though they are drowning. Having nothing to stand on, being pummelled by waves, unable to catch a breath and with no sight of help or the shore. This type of depression is a torturous combination of distress, anxiety and hopelessness where you just cannot stop the negative fearful ruminations swirling in your mind. There is no calm, no silence and no peace.

Feeling nothing 

The metaphor I find most disturbing is when depressed patients describe feeling ‘nothing’. So often people will express feeling empty and their lives as grey. Nothingness. And I am always reminded of the 1980s movie ‘Neverending Story’ where everything that was magical and creative and hopeful had been swallowed up by ‘The Nothing’ – an empty energy that consumed everything in its way. How terrifying it must be to feel nothing. No hope, no joy, no excitement, not even sadness or fear. Just nothing. Blank. And no matter what you do or how hard you try, you just feel nothing. How horrifying it must be to hug someone you love, or have to get up each morning and go to school, or go to work and have to paste on a smile and chat about the weekend while you feel nothing. I can only imagine the desperation to feel something. Anything. This depression is you sitting on your bed and staring at the ceiling for hours. Waiting for it to end. 

Something that stands out to me as a common theme among all of these metaphors is this: if a monster is following you around, nobody wants to come near you. If you are gasping for breath and swallowing water drowning in the sea – there is nobody around to save you. If you float through your days in a bubble of nothingness – you are alone. The antidote to suicidality is connection. It is being willing to spend time with someone who has a growling, slobbering, and mangy stray dog following them. It is listening to someone who is struggling and thrashing, terrified of drowning. It is being brave enough to enter nothingness and to realise that you too could horrifyingly easily feel empty and grey too. Now we need to be cautious. It is dangerous dealing with an angry dog, or trying so save a drowning person or rescuing someone floating off into space. We cannot do it alone and we cannot do it without experts. But the first step is to shout, or speak or whisper: ‘Hello’. ‘I’m here’. ‘I’ll get help’. Without fear or judgement or discrimination. But with the deep understanding that being human is a treacherous thing. And recalling the times when a safe, strong hand reached out to pull us away from danger. Because you see, we are all vulnerable to being followed by a black dog. Or being washed away by a wave. Or being consumed by The Nothing. 

Grab hold of the stretched out hand 

What makes us human is our vulnerability. To diseases of the body. And diseases of the mind. And what makes us human is our willingness to see our own vulnerabilities in others. I will reach out and help you because I too have needed help. So this World Suicide Prevention Day let us tame black dogs and send life rafts out to stormy seas. Let us be the solid ground to tether those who are floating away into outer space. And when we find ourselves followed or drowning or adrift – let us too reach past the snarling and swirling and emptiness to touch the outstretched hands of those who are here for us. Because they are here. We are right here. But in order to be rescued from the attacking beast, or the crashing waves or the airlessness of space, you have to grab hold of the hand stretched out toward you. 

If you or someone you know are experiencing suicidal thoughts or feelings of depression please tell someone you trust how you feel and make contact with one of the 24-hour support lines such as The South African Depression and Anxiety Group (Sadag) (+27 800-567-567) or LifeLine (+27 861-322-322).

A summary of an inaugural lecture delivered by Prof Robert Bragg at the University of the Free State:

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
