An evaluation of the knowledge, attitude and practices of South African university students regarding the use of emergency contraception and of art as an advocacy tool

Background: This study assessed the knowledge and use of emergency contraception (EC) against the background of current sexual practicesamong a multi-racial student population at the Durban University of Technology (DUT) in the province of KwaZulu-Natal, South Africa. In addition, the use of art as an advocacy tool in promoting awareness of EC and related sexual issues was also evaluated. Methods: A random sample of 162 students with equal representation of race and gender was interviewed. The questionnaire used addressed knowledge, attitudes and practices regarding contraception, with emphasis on EC and current sexual practices. It was administered by trained interviewers at three different sites at the DUT, where the Kara Walker image was also displayed on banners by Art for Humanity (AFH). Results: Over 77% of participants indicated that EC was some sort of birth control or contraceptive method. Only 51% of the respondents felt that ECwas a good form of contraception and 27% of all students indicated that it should not be used at all. However, given a choice, 66% of African students would use it, compared to 46% Indian, 31% coloured and 52% white students. The various levels of undergraduate study (i.e. first to third year) did not impact on the level of knowledge of or attitude towards the use of EC among students. Students had health and social concerns, including that if more men were informed about EC, they may use it to pressure women into having unprotected sex. Over 90% of students knew that EC did not provide protection from HIV, AIDS and STDs. Of the 162 students questioned, only 21% had seen the Kara Walker poster and their responses to the banner were varied. While a few students thought that it was an inappropriate portrayal of women, most students who saw the banner thought it was effective in drawing attention to the consequences of unsafe sexual practices.Conclusion: It is imperative that concise information and pre- and post-counselling be provided by health care professionals to empower individuals at tertiary institutions to make informed choices with respect to reproductive health. Proper dissemination of information will create awareness and enhance wider acceptance and the use of the arts as an advocacy tool may further promote health education

Optimising invasive fish management in the context of invasive species legislation in South Africa

South Africa hosts a large number of non-native freshwater fishes that were introduced for various industries. Many of these species are now listed under the National Environmental Management: Biodiversity Act (NEM:BA) Alien and Invasive Species (A&IS) lists and regulations, though the practical options available to conservation agencies to effectively manage these fishes vary greatly among species and regions. Objectives & methods: We assessed the history and status of national legislation pertaining to invasive freshwater fishes, and the practical implications of the legislation for managing different species with contrasting distributions, impacts and utilisation value. Results: The smallmouth bass, despite being a potential conflict-generating species, is fairly straightforward to manage based on current legislation. Two species of trout, which remain absent from the NEM:BA A&IS lists because of ongoing consultation with stakeholders, continue to be managed in regions like the Western Cape province using existing provincial legislation. To maximise the limited capacity for management within conservation agencies, we proposed a decision-support tool that prioritises invasive fish populations that represent high environmental risk and low potential for conflict with stakeholders. Using three case studies, we demonstrated how the tool can be used to set management goals of 'eradicate', 'manage against impacts and further spread' and 'continue to monitor population' as the most pragmatic solutions given the state of an invasion, its socio-economic impact and the capacity of the responsible agency to act. Conclusion: By choosing a pragmatic management strategy, conservation agencies can maximise the effective deployment of limited resources, while minimising avoidable conflicts with stakeholders.EM201

Life within chronic care: is this a service or sentence?

Background: Understanding the meaning of one’s lived experiences improves one’s understanding of what it means to be human, in association with the social, cultural and historical context in which being a human occurs. The authors in this study describe the lived experiences of residents within a chronic care facility including the practitioner and family perspectives.Methods: A qualitative approach was employed with a single-site, descriptive, instrumental case study design. Purposive sampling was utilised to select the chronic facility. Multiple sources of evidence included narratives, semi-structured interviews with staff, residents and family members, and activity profiles of the residents augmented by an ergonomic evaluation of the facility. Content analysis using within-case analysis was implemented.Results: The greatest impact on the quality of the resident’s lived experiences emanates from the physical, organisational and social environments in which they reside. Limited resources, poor staff attitudes and routines that are enforced both on the staff of the facility and the residents appear to reduce optimal functioning within the facility. Furthermore the residents’ intrinsic motivation, presence of enforced idleness, learned helplessness and institutionalisation is often intensified and becomes characteristic of the residents lived experiences.Discussion: The lived experiences of the residents are described according to quality of life indicators that were identified during the study and supported by literature. These include the influence of the physical, social and organizational environments on the residents’ functional status, which comprises physical well-being and emotional well-being and engagement in meaningful occupations including social interaction and relationships with other individuals.Conclusions: Findings of this study may be valuable in understanding and facilitating a positive change in service delivery within chronic care centres.Keywords: chronic care, institutionalisation, lived experiences, residents, occupational deprivatio

The neural correlates of intimate partner violence in women

Objective: To examine hippocampal volume and white matter tracts in women with and without intimate partner violence (IPV). Method: Nineteen women with IPV exposure in the last year, and 21 women without IPV exposure in the last year underwent structural magnetic resonance imaging (MRI) including diffusion tensor imaging (DTI) sequences. Additional data on alcohol use and presence of psychiatric disorder was collected. Differences in fractional anisotropy (FA) between the two groups were examined, using a statistical model that included demographic measures, alcohol use and psychiatric disorder. Results: IPV subjects did not demonstrate significantly different hippocampal volumes compared to subjects without recent IPV. FA was, however, significantly reduced in the body of the corpus callosum of IPV subjects. Adjusting for age, alcohol use, smoking and psychiatric diagnosis did not change the significance of the result. Conclusion: Data on hippocampal volume in IPV are inconsistent, perhaps reflecting the fact that multiple factors influence this measure. Reduced FA in the body of the corpus callosum in IPV suggests altered integrity of this white matter tract; additional work is needed to address the underlying mechanisms and clinical correlates of this finding

Risk factors for atherosclerosis - can they be used to identify the patient with multisystem atherosclerosis?

Risk factors are often used in preventive care programmes to identify the patient at particular risk for developing atherosclerosis. Risk factors for atherosclerosis have also been shown to be linked to the presence of the disease at a given time, a fact that may be helpful when screening for additional atherosclerotic disease in the known arteriopath. Risk factors .were recorded in 471 patients admi"ed to hospital with symptoms of atherosclerosis. In patients admi"ed primarily with peripheral vascular disease, risk factors linked to the presence of additional coronary artery disease were a family history of ischaemic heart disease (odds ratio = 2,6), the presence of carotid artery disease (odds ratio = 1,9) and high fasting serum triglyceride levels (P < 0,04). Grouping these factors together usin.g logistic regression, ischaemic heart disease could be predicted with a sensitivity of 72% and a specificity of 43%. Patients admitted with carotid artery disease were more likely to have ischaemic heart disease in the presence of peripheral vascular disease (odds ratio = 1,9) and a raised serum cholesterol level (P < 0,02), while female gender (odds ratio = 2,9) and an increase in age (P< 0,001) were linked to an increased prevalence of concomitant atherosclerosis in patients admmed with acute myocardial infarction or for elective coronary artery bypass surgery. Using an age cut-off point, additional atherosclerosis could be predicted with a sensitivity of 32% and a specificity of 88% in these patients

The identification of Mycoplasma mycoides mycoides LC as the aetiological agent of balanoposthitis and vulvovaginitis in sheep in South Africa

Clinical ulcerative balanoposthitis and vulvovaginitis was experimentally reproduced in 14 sheep infected with a Mycoplasma mycoides mycoides LC field strain, isolated from the Straussheim Dorper stud. The study encompassed a series of field observations, a therapeutic trial and experimental investigations. A wide range of bacteria and various mycoplasma spp., but no viruses, were isolated from a large number of infected animals.The articles have been scanned in colour with a HP Scanjet 5590; 600dpi.
