As a mental healthcare provider, I approach the end of every year with some trepidation. As soon as the August winds start to blow in Bloemfontein, we tend to see a distinct increase in our community’s psychological distress. The year 2020 has not spared us this increased burden of suffering.

This year has presented humanity with extreme challenges and our university community has felt this to our core. The latest research indicates that the South African population has been affected by the pandemic in various ways and on various levels but none less severe than our psychological health. One in three South Africans will present with a psychological disorder during our lifetime (and this was prior to the Covid-19 outbreak); and the effects of the pandemic have caused a significant rise in depression, anxiety and trauma symptoms among South Africans.

In mourning 

We are experiencing exceptionally high levels of financial stress due to the impact of the disease and lockdown on our economy. We have endured months of social distancing, fears surrounding our own health and the well-being of our loved ones, our financial safety, managing our children’s home-schooling, adapting to distance-learning and concerns about the academic year being salvaged. We have had to experience loss after loss. We mourn loved ones, colleagues and acquaintances that have become ill or passed away due to the pandemic. We have mourned the loss of our normal lives. The hugs, handshakes, casually touching someone’s arm, the shows, sporting events, weddings, graduations and braais we took as for granted. We grieve for a time before sanitising and masks and avoiding contact with our fellow humans was the daily norm. We miss our offices and tearoom banter. We miss being with our students. Amid all of these losses we know that our rates of gender-based violence, suicide and substance abuse have increased. When people are forced to spend time with others in confined spaces amid increasing financial, health and social stressors, frustration and fear may lead to damaging reactions and dysfunctional coping mechanisms. 

World Mental Health Awareness Day on 10 October could not have arrived at a better time. This year the World Health Organisation is encouraging investment into mental healthcare across the globe. While this is an essential step in increasing access to mental healthcare services, it is also only one aspect in the use of psychological treatment resources. One of our most important barriers to providing mental healthcare often lies within us. Mental illness remains one of the most stigmatised conditions in society; even though each one of us will be affected by our own, or our loved ones’ mental-health problems at some point during our lives. Some of the common problematic and erroneous beliefs society holds about people who struggle with mental illness is that they are somehow deviant, dangerous, weak or even faking it. Unfortunately, our healthcare workers are not immune to such prejudicial attitudes and neither are their patients. Self-stigmatisation occurs when we internalise these discriminatory generalisations and fail to access mental health care because we believe that we should be stronger, or just pull ourselves together or worry about the impact of receiving a psychiatric diagnosis on our career or our relationships. 

Silence is one of the most insidious barriers 

We fear being judged by our healthcare providers, our employers, colleagues, family and friends. This culminates in a situation where we lead lives of quiet desperation – numbing our distress with distractions and substances and perhaps even work. The silence surrounding mental health is one of the most insidious barriers to accessing treatment – because you cannot be helped if nobody knows you are suffering. This is the tragedy of suicide, which more frequently than we wish to believe, is the final symptom of depression and severe psychological illness. I have had to assist more patients than I care to recall to work through the trauma and grief of losing a loved one to suicide. Perhaps one of the most tragic aspects of this is that almost all would sit in utter shock recalling how their loved one had seemed fine. How this came out of the blue. How he or she had never told anyone how difficult life had become for them. How hard it was to get out of bed each morning. How much energy it took to go through the motions of a normal day. How ultimately they were so ill that they believed that they were a burden to their family and friends. How they could see no hope of relief from their pain other than to end their lives. And nobody knew. They were silent in their suffering because of fear of stigma, judgement, rejection or being viewed as a burden. 

The surprising gift of the pandemic

Mental illness does not discriminate against anyone. It affects professors, students, support staff and the greater university community equally. Nobody is spared these struggles. This is what we all share,   the human experience of life's seasons which we cannot do alone. When we need the help of more than our resilience, support structure and exercise routine. This is where the pandemic has brought some unexpected gifts. Prior to March of this year, it was very unusual for psychologists to provide online or telephonic therapy. In fact, many medical aids were uncomfortable covering teletherapy. Once we had no other alternative; however, we all had to adapt. Suddenly I no longer only saw patients who were able to attend sessions at my office. Now I could assist students and doctors who were in lockdown across the country. I could refer patients to the appropriate therapist, irrespective of where they were. Patients no longer had to negotiate the uncomfortable experience of waiting in a psychologist's waiting room or being seen leaving an office looking upset or need to take time off work to attend a session. Now patients can access their psychotherapist from the containment and confidentiality of their own space, and we in turn, are more freely available as we are not bound to a specific venue. 

Receiving psychological treatment is becoming as normal a part of well-being as going for a run, or eating healthily or spending time with our social support system. And this is what is going to save lives. The more we normalise the use of psychological services, the less stigma and silencing we will be subjected to.

We survived a pandemic 

As a clinical psychologist I proudly tell my students, colleagues and patients that I have my own psychotherapist without whom I would not be the therapist, colleague, friend and mom I am. There is no shame in owning our vulnerability and reaching out for assistance in order to make meaningful and even enjoyable the few journeys around the sun that we have left. So this October of 2020 should be the month when we start the conversation about our mental health. And by doing, so we permit those around us to do the same. We have survived a pandemic that changed the world and our daily lives. It's okay not to be okay.

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
