Dr Annamarie van Jaarsveld believes occupational therapy is important
Dr Annamarie van Jaarsveld believes occupational therapy is important for personal well-being.
On 27 October the profession of occupational therapy is promoted and celebrated internationally. The theme for this year is “Celebrating our global community.” Due to the theme of this year occupational therapists form all over the globe will be able to join in the World Federation for Occupational Therapy Virtual Exchange webinars.
 
Occupational therapy promotes health and well-being through occupation. The overarching goal of occupational therapy is to enable people to participate in the activities of everyday life that is meaningful to them. Occupational therapists work with people and communities in an effort to enable people of all ages to live life to its fullest by helping them maintain and/or promote health, and prevent (or live better with) injury, illness, or disability. 

Common occupational therapy interventions include helping children with disabilities to participate fully in school and social situations, helping people recovering from injury to regain skills, and providing supports for older adults experiencing physical and cognitive changes. Occupational and social justice along with occupational deprivation are core within the profession as it relates to oppression or restrictions to participation in occupation impacting on well-being and quality of life. 

Taking the lead in Sensory Integration research

Dr Annamarie van Jaarsveld is a lecturer in the Department of Occupational Therapy, and she is at the forefront of research in sensory integration, a specialist field within occupational therapy. Apart from completing her PhD on the curriculum design of a South African professional master’s degree qualification in sensory integration, she is also heading the South African leg of a large international study in collaboration with sensory integration experts all over the world.

Dr Van Jaarsveld explains: “The Evaluation of Ayres Sensory Integration (EASI) is a new test which aims to be a first of its kind in the field of sensory integration and occupational therapy. It will be inexpensive, electronically accessible and practical, and standardised on an international population which includes a South African sample. This will make the test accessible and useful for therapists in South Africa to be able to assess sensory integration related function of all South African children in a valid and reliable manner.” 

In addition to being the South African lead on the international EASI standardisation study, Annamarie was selected as the chairperson of the Board of Council Meetings of the International Council for Education in Ayres Sensory Integration (ICEASI). She is also the International Liaison on the board of the South African Institute for Sensory Integration. 

Annamarie’s passion for sensory integration and the application of a highly researched and specialised subfield where the expertise and guidance are provided by a first-world country is not only evident in her research, but also in various community projects that she is involved in. One such a project, Back to Urth Playgrounds, aims to make sensory integration relevant to the needs of South African children and their families struggling with sensory integration issues within the realities of diverse contexts. Through the designing of sustainable playgrounds based on sensory integration theory, building the playgrounds in collaboration with the community and other stakeholders, and equipping educators and caregivers with knowledge on how to encourage children to use the playgrounds, Annamarie has contributed to making the potential of sensory integration-based intervention accessible to the most under-resourced of areas. 

With the 27th of October being International Occupational Therapy Day, Annamarie says: “Sensory integration is not only the best researched field within occupational therapy, providing more and more best practice evidence through rigorous research, it is also becoming more available to children and families from all walks of life – indeed exciting times ahead for this field of practice and it remains a privilege to be involved in it”.

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
