A fleeting thought of suicide is not an uncommon experience for quite a number of people, especially during moments of stress or strife. Sadly, for some, their surrounding circumstances or confronting situations seem so insurmountable that these evoke feelings of despair, hopelessness, and constrict the individual reasoning abilities to a point where suicide seems to be the only reasonable solution to their problem. Thinking about ending one’s life (suicide ideation) on a frequent basis can lead to increased pre-occupation with suicidal thoughts, to the point where a detailed plan is put into action – also called a suicide attempt. Optimistically, we hope that the suicide attempt is effectively managed towards a complete recovery, with the necessary interventions. If loss of life has occurred due to the suicide attempt, the individual has completed suicide. Although the suicidal mindset focuses on eradicating the pain or stressor, the left-behinds (surviving family/friends) are often shocked or disillusioned by these acts, an aspect often less discussed. 

A glance into suicidal thinking

“Take the saddest/most embarrassing moment in your life and multiply this by 1 000
Then subtract your libido, self-confidence, and appetite
Now add feelings of slipping deeper and deeper into a state of pain and non-resolution”
(Author unknown)
This suicidal experience is associated with thoughts such as:
“There is no point in going on”
“Nothing I do will be able to help me”
“I’m probably better off dead”

“Even though I try, I will make no difference”


Who are most at risk?

The global trend of suicide prevalence has changed over the past few decades. Initially, the adult and elderly population were at higher risk, which was in line with the age-related stressors (loss of employment, financial debt, divorce, illness, experiencing a growing number of losses, as well as the experience of loneliness) during these age groups. Currently, the suicide picture has significantly swung the pendulum to the point where the age group of 15-29 years is at the highest risk of suicide (WHO, 2021). Accordingly, one person complete suicide every 40 seconds, and for each suicide at least 20 or more persons will attempt suicide. Within the confines of South Africa, the South African Depression and Anxiety Group (SADAG) expressed much concern about the youth, given that 17,6% of teens considered attempting suicide, while more than 20% of 18-year-olds had one or more suicide attempt. These alarming figures cannot be viewed with complacency and need our urgent attention as community, professionals, and government. 

Why our youth are at higher risk

Transitioning into adolescence and then into early adulthood is typically accompanied by a number of challenges and adjustments. Such challenges are varied, and depending on an individual’s resources and support, many social exposures (alcohol and other recreational substances, romantic relationship challenges, competitive educational environments, poor parent-child relationships, to name but a few) may be satisfactorily traversed. Unfortunately, many of these challenges transgress into stress factors which, if allowed to escalate, can negatively impact on the individual’s mental health.

In addition to these social pressures, South Africa is viewed as one of the more violent countries in the world, while its high unemployment rate and associated repercussions have placed inordinate stressors on family well-being (OSAC, 2020). Compounding this effect, is the presence of uncertainty in the socio-political arena. These economic uncertainties contribute to a strained societal environment in which the most vulnerable are often neglected in terms of adequate and efficient resource provision. The youth are more impulsive and less skilled in problem solving, thereby increasing their vulnerability to the above stressors. 

Reading the warning signs 

IS PATH WARM (APA, 2010)
I – Ideation: Talking/asking about suicide content
S – Substance use: Substances can disinhibit protective impulses and serve as a means to escape the unbearable/painful thoughts
P – Purposelessness: Questioning meaning in life, including your purpose
A – Anxiety: Agitated and emotionally difficult 
T – Trapped: Feeling that this situation is inescapable
H – Hopelessness: Loss of purpose and meaning
W – Withdrawal: From family, friends, social and community activities, and previously engaged-in groups 
A – Anger: Rage, uncontrollable anger, vengefulness
R – Recklessness: Don’t care attitude, inconsiderate and reckless actions seemingly without cause 
M – Mood changes: Mood improves in a positive manner, happier, more agreeable, etc.

Tell-tale warning signs:
• Significant changes in academic marks or uncharacteristic absenteeism from classes/lectures
• Uncharacteristic sharing, to the point of giving away precious possessions
Risk factors for suicide
The presence of risk factors compounds the probability that suicide behaviour may occur (Turecki & Brent, 2016; WHO, 2021).
• Previous suicide attempt: Still the number one factor that predicts future attempts
• History of suicide: Family history or attempts by close friends increase risk
• Alcohol/substances: Decreases inhibitions and causes mind-altering changes 
• Life situations: Marital separation, romantic break-up, difficulty adjusting to new circumstances
• Recent loss: Death of a person very close, physical amputation or loss of other physical functions
• Limited social resources: Poor support system by family, friends, etc.
• Psychiatric history: History of a mental illness or presence of psychotic conditions
• Various forms of trauma
• Stressful life experiences: Household violence, criminal violence, disaster situations, physical illness, chronic diseases, financial or legal difficulties

Responding to suicide

Suicidal thinking consists of constrictive thought patterns that seem polarised; however, research has indicated that reasoning is still possible and that a suicidal individual can change their mind (Yasgur, 2016). For the individual who is suicidal, the following ‘tips’ may prove useful (Malema, 2019; WHO, 2019).
• Take your mind off and rest by counting digits backward from 10 to 1
• If you feel angry, avoid the situation, but face it again after 10 minutes
• Accept help from colleagues and friends to deal with your worry
• Participate in distraction activities, e.g., regular exercise, regular sleep, or good nutrition
• Seek professional help, as this is key in helping you deal with your problems
As a family member or friend, you may become aware that someone is suicidal
• Do something now. Avoid delaying, ignoring, or denying
• It is a shock to your system. Acknowledge it, BUT know that you are targeted for help
• Support emotionally. Be there for them 
• If you can, enquire about possible methods being considered and, where possible, remove any dangerous items
• Get extra help and accompany them. Make suggestions and listen to the person’s wishes regarding who they might talk to

• Do not withdraw suddenly after the person has been stabilised

Professional help is available and can make a big difference. Consult a GP or go to your local casualty department, where you should receive some help and be referred to a psychologist and/or psychiatrist, depending on the need. These professionals will be able to do a risk assessment and advise accordingly in terms of treatment and a psychotherapy plan to assist, support, and guide the person towards coping more effectively with life challenges.

Concluding

COVID-19 is the most recent global health challenge that has placed pressure on health facilities. Most notably, developing economies seem to have been under greater response pressure in managing the pandemic. Some evidence suggests that a short-term decrease in suicide rates following the immediate aftermath of the pandemic onset was noticeable. Disaster events seem to trigger what is called the ‘pulling together effect’, leading to an environment filled with social concerns, cohesiveness – including the presence of social and emotional support – which are also needs that buffer the effects of suicide behaviour (Gordon et al., 2011; Wilkinson & Pickett, 2020; Zortea et al., 2020). Unfortunately, as the levels of hope in managing the pandemic have become more palpable, the ‘pulling together effect’ tends to decrease in effect. As the presence of the pandemic extended over time, the measurable risk of depression and suicide screening numbers steadily increased, especially in females (Mayne et al., 2021).

Suicide has been a public health challenge for many centuries, and we have learnt a great deal about the personal, social, and interactional dynamics related to suicide behaviour. As mentioned earlier, effective management warrants responses from all levels of society, and South Africa is currently in urgent need of a national suicide prevention strategy policy. Unfortunately, the existing National Mental Health Policy Framework and Strategy Plan lacks detailed content and is not suicide prevention specific. According to the WHO (2021), the most effective response to suicide requires every nation to implement a comprehensive and multi-sectoral strategy approach plan.

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.
