Dr Nashua Naicker
Dr Nashua Naicker, lecturer and Chairperson: Learning and Teaching Committee (SoHRS) in the Department of Optometry, UFS School of Health and Rehabilitation Sciences, graduated on Thursday (April 18) with the degree Doctor of Philosophy in Health Professions Education.

A strong need to improve the general standing of optometry as a profession and to create lifelong learning opportunities for locally trained optometrists beyond what currently exists, is what led Dr Nashua Naicker to pursue a PhD in this field.

Dr Naicker, lecturer, and Chairperson: Learning and Teaching Committee (SoHRS) in the Department of Optometry, UFS School of Health and Rehabilitation Sciences, says he feels an overwhelming sense of relief with a keen sense accomplishment by achieving what he set out to through persistence in the face of adversity.

He graduated on Thursday (18 April) at the Faculty of Health Sciences April graduation ceremony with the degree Doctor of Philosophy in Health Professions Education through the Division of Health Sciences Education. “I am pleased and hope to change the narrative on this new path as an accredited researcher from ‘how long are you going to take to finish?’ to ‘what have you learnt in this journey?’. We are far too focused on chasing a timeline rather than focusing on the contribution that one makes and the self-development in this journey of discovery,” says Dr Naicker. 

His supervisor was Prof Alvin J Munsamy from University of KwaZulu-Natal (UKZN) and co-supervisor Dr CB Written from the UFS.  

Need for educational expansion

His research was focused on establishing a framework for postgraduate programmes in specialty fields of optometry for South Africa. The investigation was carried out with practising optometrists as the primary stakeholders and with optometric academics as the custodians for education and training in the country.

“With an overwhelming need for educational expansion found in this investigation, a conceptual framework was proposed as the innovation to take the profession forward in South Africa. Improving patient care from being upskilled and receiving professional recognition for the additional competencies and proficiencies that would be gained, was the motivating factors identified by optometrists to consider further education and training,” says Dr Naicker.

According to him, being in the educational fraternity for almost two decades and as a former education committee member of the professional board of optometry, he was able to see where the shortcomings were in the profession which set him on this path to pursue this research. With most optometrists in clinical practice and no clinical postgraduate qualifications available except pure research-based qualifications in SA, Dr Naicker explains that this hindered optometrists’ professional trajectory and career path opportunities into various special interest areas. 

“By developing a framework for horizontal articulation pathways towards coursework postgraduate qualifications in various clinical specialty fields, this would be the contribution in addressing the educational gap that would guide higher education institutions in their programme development process. The beneficiaries of this expansion would not only be the health professionals but the patients who access optometric care from the optometrists who would have advanced skills and competencies to deliver comprehensive eye care services.”

Stayed motivated

Dr Naicker says the journey to his PhD was challenging from the outset as the country went into hard lockdown due the COVID-19 pandemic just five weeks after he registered for his PhD. Working on a PhD was not a priority at the time when your survival and that of your loved ones was uncertain as thousands of people fell victim to the coronavirus. Further to this, he continues, multiple changes to his supervisory team and the overhaul and revitalisation of the administration and management of the UFS Division of Health Sciences Education, also impacted his progress in his doctoral research at that time. He had felt despondent after a year of being registered when stability arrived with supervisory assistance that re-ignited his drive to pick up the slack and keep moving forward.

“The words ‘push through it’ were verbalised to me by a stranger I met in passing.  While chatting about research I found those three words to be so profound and with such depth that they resonated with my experience of facing adversity but remaining vigilant to preservere and not drop the baton in the race against time to conclude my research. Gaslighting yourself and questioning your potential to complete a PhD only compounds your procrastination which was all too apparent. The goal is to rise above the self-doubt, brush off the devil with the fork sitting on your shoulder and just ‘push through it’.”

Dr Naicker, who is currently supervising four master’s of optometry students in their research undertaking, as well as undergraduate research projects, says he is in the process of publishing the research manuscripts generated from his PhD and is also part of a task team with the professional Board of Optometry for setting up the board exams for foreign-qualified optometrists. He would also like to work on research involving educating the educators of visually impaired learners.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
