    Aldhoun, Jitka A; Horne, Elizabeth C

    2015-01-01

    During the years 2009-2012, faeces of African penguins (Spheniscus demersus L.) from South African rehabilitation centres were examined for helminths. In total, 46 out 555 samples (8.29 %), mostly belonging to adult birds, were found to contain oval schistosome eggs with a spine on one pole. Their dimensions were 153.21 ± 9.07 × 87.14 ± 8.67 μm. Selected DNA fragments (18S, 28S and ITS rDNA) were sequenced and compared to other schistosome isolates deposited in GenBank. The shape of the eggs suggests that they belong to the genus Gigantobilharzia; however, due to the insufficient stage of knowledge of the genus and limited number of species available for comparison, we were not able to assign the isolate unambiguously to this genus based on either the egg morphology or the results of molecular analysis.

  14. Enslaved Africans and doctors in South Carolina.

    PubMed Central

    Goodson, Martia Graham

    2003-01-01

    This interpretation of the relationship between enslavement and American medicine in 19th century South Carolina reveals the intimacy that existed between Africans enslaved in that state and the doctors who practiced and taught there. Enslaved Africans were resourceful and reliable medical figures in the slave community. Their knowledge of medical botany permeated the slave quarters and plantation hospitals and was appropriated into southern medical knowledge. The trajectories of the careers of three South Carolina physicians are tied to their practice around and on the enslaved. The beginnings of gynecological surgery are linked to 1840s experimentation on enslaved African women performed by one of them. PMID:12749683

    Wyngaardt, S. M.; Newman, R. T.; Lindsay, R.; Buffler, A.; de Meijer, R.; Maleka, P.; Bezuidenhout, J.; Nchodu, R.; van Rooyen, M.; Ndlovu, Z.

    Over the past two years there has been discussion among South African physicists about the possibility of establishing a deep underground physics laboratory to study, amongst others, double beta decay, geoneutrinos, reactor neutrinos and dark matter. As a step towards a full proposal for such a laboratory a number of smaller programmes are currently being performed to investigate feasibility of the Huguenot Tunnel in the Du Toitskloof Mountains near Paarl (Western Cape, South Africa) as a possible sight for the South African Underground Laboratory facility. The programme includes measurements of radon in air (using electret ion chambers and alpha spectroscopy), background gammaray measurements (inside/outside) the tunnel using scintillator (inorganic) detectors, cosmic ray measurements using organic scintillators and radiometric analyses of representative rock samples.

  20. An overview of South African psychology.

    PubMed

    Cooper, Saths; Nicholas, Lionel

    2012-01-01

    This overview of psychology in South Africa presents a concise and historical account of its science and practice, from its early origins in the late nineteenth century to the present, and traces seminal influences on the discipline. It is a review of how psychology in South Africa developed over more than a century to become one of the most popular subjects in universities and an established and recognized profession, whose members play a variety of roles in the South African polity and larger society. The impact that apartheid racism had on key aspects of psychology's development is traversed, and the influences that previous ruling party politics had on professional psychological organizations are delineated. The unification of psychology under the Psychological Society of South Africa, a few months before the advent of democracy in South Africa, is explicated. The protection of the title of psychologist in law and certain other changes in the legislative environment, enabling a greater role for psychologists, are reported. The primary research sites for psychology and its funding and the main university psychology programs are described, as are the requirements for registration and licensure. The genesis and the importance of the work of internationally acclaimed South African psychologists, such as J. Wolpe and A. A. Lazarus, are contextualized. With the increased participation of progressive black psychologists in leadership and research in the past two decades, a transformed psychology has the potential to play a significant role in addressing human issues confronting South Africa.

  3. Astronomy for teachers: A South African Perspective

    NASA Astrophysics Data System (ADS)

    de Witt, Aletha; West, Marion; Leeuw, Lerothodi; Gouws, Eldrie

    2015-08-01

    South Africa has nominated Astronomy as a “flagship science” and aims to be an international Astronomy hub through projects such as the Square Kilometre Array (SKA) and the South African Large Telescope (SALT). These projects open up career opportunities in maths, science and engineering and therefore offers a very real door for learners to enter into careers in science and technology through Astronomy. However, the Trends in International Mathematics and Science Survey (TIMSS), the Global Competitiveness Report (GCR) and Annual National Assessment (ANA) have highlighted that South Africa’s Science and Mathematics education is in a critical condition and that South African learners score amongst the worst in the world in both these subjects. In South Africa Astronomy is generally regarded as the worst taught and most avoided Natural Science knowledge strand, and most teachers that specialised in Natural Sciences, never covered Astronomy in their training.In order to address these issues a collaborative project between the University of South Africa (UNISA) and the Hartebeesthoek Radio Astronomy Observatory (HartRAO) was initiated, which aims to assist teachers to gain more knowledge and skills so that they can teach Astronomy with confidence. By collaborating we aim to ensure that the level of astronomy development will be raised in both South Africa and the rest of Africa.With the focus on Teaching and Learning, the research was conducted within a quantitative paradigm and 600 structured questionnaires were administered to Natural Science teachers in Public primary schools in Gauteng, South Africa. This paper reports the findings of this research and makes recommendations on how to assist teachers to teach Astronomy with confidence.

  4. South African TOPEX/Poseidon altimeter experiment

    Gruendlingh, Marten L.; Shannon, L. V.; Lutjeharms, J. R.

    1991-01-01

    The area surrounding the southern tip of Africa contains a juxtaposition of a variety of interesting and climatically relevant features. On the Indian Ocean side, the Agulhas Current with its tributaries form a conduit through which much of the southern Indian Ocean surface flow is focused. South of the continent, this flow is fragmented and partially injected into the Atlantic Ocean and across the Subtropical Convergence into the Southern Ocean. To the west of the subcontinent, the circulation of the South Atlantic subtropical gyre in the Cape Basin interacts with the vigorous Benguela upwelling regime. The creation, transformation, and transport of water masses and the intra-annual and climatic importance of all these processes have been specifically recognized by the World Ocean Circulation Experiment (WOCE). The South African TOPEX/POSEIDON Altimeter Experiment addresses many of these issues through four mutually complementary and interrelated subprojects.

  6. Appendicectomy prevalences in South African adolescents.

    PubMed

    Walker, A R; Walker, B F; Duvenhage, A; Jones, J; Ncongwane, J; Segal, I

    1982-01-01

    From questioning 16,939 South African pupils of 16-18 years, in 56 high schools, mean prevalences of appendicectomies in representative segments of ethnic groups were found to be: rural Blacks 0.6%; urban Blacks 0.7%; Indians, 2.9%; Coloureds (Eur-African-Malay), 1.7%; Whites, 10.5%. Percentages in the sexes were similar. Only those of Indian and Coloured pupils appear to be increasing. Blacks and Whites, respectively, have high and low intakes of fibre-containing foods, which are negatively correlated with appendicectomy prevalences. However, although intakes of fibre-containing foods are slightly higher in Indians and Coloureds than in Whites, the former's appendicectomy prevalences are lower than would be dietarily expected.

  7. Crowd psychology in South African murder trials.

    PubMed

    Colman, A M

    1991-10-01

    South African courts have recently accepted social psychological phenomena as extenuating factors in murder trials. In one important case, eight railway workers were convicted of murdering four strike breakers during an industrial dispute. The court accepted conformity, obedience, group polarization, deindividuation, bystander apathy, and other well-established psychological phenomena as extenuating factors for four of the eight defendants, but sentenced the others to death. In a second trial, death sentences of five defendants for the "necklace" killing of a young woman were reduced to 20 months imprisonment in the light of similar social psychological evidence. Practical and ethical issues arising from expert psychological testimony are discussed.

  8. South African food allergy consensus document 2014.

    2015-01-01

    The prevalence of food allergy is increasing worldwide and is an important cause of anaphylaxis. There are no local South African food allergy guidelines. This document was devised by the Allergy Society of South Africa (ALLSA), the South African Gastroenterology Society (SAGES) and the Association for Dietetics in South Africa (ADSA). Subjects may have reactions to more than one food, and different types and severity of reactions to different foods may coexist in one individual. A detailed history directed at identifying the type and severity of possible reactions is essential for every food allergen under consideration. Skin-prick tests and specific immunoglobulin E (IgE) (ImmunoCAP) tests prove IgE sensitisation rather than clinical reactivity. The magnitude of sensitisation combined with the history may be sufficient to ascribe causality, but where this is not possible an incremental oral food challenge may be required to assess tolerance or clinical allergy. For milder non-IgE-mediated conditions a diagnostic elimination diet may be followed with food re-introduction at home to assess causality. The primary therapy for food allergy is strict avoidance of the offending food/s, taking into account nutritional status and provision of alternative sources of nutrients. Acute management of severe reactions requires prompt intramuscular administration of adrenaline 0.01 mg/kg and basic resuscitation. Adjunctive therapy includes antihistamines, bronchodilators and corticosteroids. Subjects with food allergy require risk assessment and those at increased risk for future severe reactions require the implementation of risk-reduction strategies, including education of the patient, families and all caregivers (including teachers), the provision of a written emergency action plan, a MedicAlert necklace or bracelet and injectable adrenaline (preferably via auto-injector) where necessary.

  9. Analysis of South African graduate degrees in science education: 1930-2000

    NASA Astrophysics Data System (ADS)

    Laugksch, Rüdiger C.

    2005-05-01

    This analysis of research conducted by graduate students at South African universities over the last 70 years is an attempt to identify the foci of South African science education research. Appropriate graduate degrees were systematically identified by interrogating electronic databases and verifying details. Title and abstract were then used to assign keywords. Overall 23% and 77% of the 469 graduate degrees identified are doctoral and master's degrees, respectively. The activity of graduate work suggests that science education as a discipline was comparatively well established in South Africa by the 1980s, although 59% of all degrees were conferred between 1991 and 2000. Following the methodology of White [2001, in V. Richardson (Ed.), Handbook of research on teaching (4th ed., pp. 457-471)]. Washington, DC: American Educational Research Association), trends in the relative frequency of keywords indicate that South African science education is broadly in line with worldwide trends in the discipline but that some differences exist. However, South African science education research appears to focus relatively more on attitudes, classrooms, curriculum issues, STS-related issues, and laboratories, and relatively less on assessment, reflection, teachers' or students' conceptions, and informal learning. Research on identified national priorities is being conducted, albeit with variable prevalence. Future opportunities in science education research lie in following a research agenda more closely matched to local contexts, and in the diversification of research focused largely on the secondary-tertiary interface.

  14. South African court rejects country's new constitution.

    PubMed

    1996-09-20

    Fundamental principles designed to ensure that South Africa's new constitution upholds a wide range of individual rights and freedoms and establishes a responsive government with a balanced separation of powers, including recognition of the role of traditional tribal leadership, were adopted into the current interim constitution shortly before the 1994 free elections which brought Nelson Mandela and the African National Congress to power. In a judgement issued on September 6, 1996, South Africa's Constitutional Court rejected the country's new draft constitution, arguing that it failed to meet the standards of nine of the 34 principles established at the Kempton Park negotiations. The Constitutional Assembly is comprised of a joint meeting of the National Assembly and Senate. One of the court's major objections to the constitution concerned the proposed structure of rule, which was seen to give inadequate power to South Africa's nine provinces as compared with the national government. However, the bill of rights was almost entirely upheld. The bill would create a favorable environment for legalized abortion and guarantee a universal right of access to health care, including reproductive health services

  15. Developing generalism in the South African context.

    PubMed

    Howe, Amanda C; Mash, Robert J; Hugo, Jannie F M

    2013-10-11

    The largest impact on the South African burden of disease will be made in community-based and primary healthcare (PHC) settings and not in referral hospitals. Medical generalism is an approach to the delivery of healthcare that routinely applies a broad and holistic perspective to the patient's problems and is a feature of PHC. A multi-professional team of generalists, who share similar values and principles, is needed to make this a reality. Ward-based outreach teams include community health workers and nurses with essential support from doctors. Expert generalists - family physicians - are required to support PHC as well as provide care at the district hospital. All require sufficient training, at scale, with greater collaboration and integration between training programmes. District clinical specialist teams are both an opportunity and a threat. The value of medical generalism needs to be explained, advocated and communicated more actively.

    South Africa provides a useful country case study for financing vaccinations. It has been an early adopter of new vaccinations and has financed these almost exclusively from domestic resources, largely through general taxation. National vaccination policy is determined by the Department of Health, based on advice from a national advisory group on immunisation. Standard health economic criteria of effectiveness, cost-effectiveness, affordability and burden of disease are used to assess whether new vaccinations should be introduced. Global guidelines and the advice of local and international experts are also helpful in making the determination to introduce new vaccines. In terms of recent decisions to introduce new vaccines against pneumococcal disease and rotavirus diarrhoea in children, the evidence has proved unequivocal. Universal rollout has been implemented even though this has led to a fivefold increase in national spending on vaccines. The total cost to government remains below 1-1.5% of public expenditures for health, which is viewed by the South African authorities as affordable and necessary given the number of lives saved and morbidity averted. To manage the rapid increase in domestic spending, efforts have been made to scale up coverage over several years, give greater attention to negotiating price reductions and, in some cases, obtain initial donations or frontloaded deliveries to facilitate earlier universal rollout. There has been strong support from a wide range of stakeholders for the early introduction of new generation vaccines. PMID:22939027

    2015-04-23

    The platyrrhine primates, or New World monkeys, are immigrant mammals whose fossil record comes from Tertiary and Quaternary sediments of South America and the Caribbean Greater Antilles. The time and place of platyrrhine origins are some of the most controversial issues in primate palaeontology, although an African Palaeogene ancestry has been presumed by most primatologists. Until now, the oldest fossil records of New World monkeys have come from Salla, Bolivia, and date to approximately 26 million years ago, or the Late Oligocene epoch. Here we report the discovery of new primates from the ?Late Eocene epoch of Amazonian Peru, which extends the fossil record of primates in South America back approximately 10 million years. The new specimens are important for understanding the origin and early evolution of modern platyrrhine primates because they bear little resemblance to any extinct or living South American primate, but they do bear striking resemblances to Eocene African anthropoids, and our phylogenetic analysis suggests a relationship with African taxa. The discovery of these new primates brings the first appearance datum of caviomorph rodents and primates in South America back into close correspondence, but raises new questions about the timing and means of arrival of these two mammalian groups.

Until now, the oldest fossil records of New World monkeys have come from Salla, Bolivia, and date to approximately 26 million years ago, or the Late Oligocene epoch. Here we report the discovery of new primates from the ?Late Eocene epoch of Amazonian Peru, which extends the fossil record of primates in South America back approximately 10 million years. The new specimens are important for understanding the origin and early evolution of modern platyrrhine primates because they bear little resemblance to any extinct or living South American primate, but they do bear striking resemblances to Eocene African anthropoids, and our phylogenetic analysis suggests a relationship with African taxa. The discovery of these new primates brings the first appearance datum of caviomorph rodents and primates in South America back into close correspondence, but raises new questions about the timing and means of arrival of these two mammalian groups.

    South Africa's academic publishing history has been profoundly influenced by its colonial heritage. This is reflected in the publication of Transactions of the South African Philosophical Society (later, the Royal Society of South Africa) from 1878. Although the Society and journal sought to promote original research about South Africa, it was modelled after the Royal Society in London and formed part of an imperial scientific community. As the local higher education institutions grew more independent and research-focused, local scholarly publishing developed as well, with university presses playing an increasingly important role. The University of South Africa (Unisa) Press started publishing departmental journals in the 1950s, with a focus on journals that 'speak to the student', and it is today the only South African university press with an active journals publishing programme. As external funding declined and the country became intellectually isolated in the high apartheid period, the Press managed to attract journals that could no longer be subsidized by learned societies and other universities. More recently, new co-publishing arrangements have brought South African journals back into an international intellectual community. Although some argue that this constitutes a re-colonization of South African knowledge production, it is also an innovative strategy for positioning local research in a global context.

  12. Petroleum geology of Cretaceous-Tertiary rift basins in Niger, Chad, and Central African Republic

    1993-08-01

    This overview of the petroleum geology of rift basins in Niger, Chad, and Central African Republic (CAR) is based on exploration work by Exxon and partners in the years 1969-1991. The work included 50,000 km of modern reflection seismic, 53 exploration wells, 1,000,000 km[sup 2] of aeromagnetic coverage, and about 10,500 km of gravity profiles. The results outline ten Cretaceous and Tertiary rift basins, which constitute a major part of the West and Central African rift system (WCARS). The rift basins derive from a multiphased geologic history dating from the Pan-African (approximately 750-550 Ma) to the Holocene. WCARS in the study area is divided into the West African rift subsystem (WAS) and the Central African rift subsystem (WAS) and the Central African rift subsystem (CAS). WAS basins in Niger and Chad are chiefly extensional, and are filled by up to 13,000 m of Lower Cretaceous to Holocene continental and marine clastics. The basins contain five oil (19-43[degrees]API) and two oil and gas accumulations in Upper Cretaceous and Eocene sandstone reservoirs. The hydrocarbons are sourced and sealed by Upper Cretaceous and Eocene marine and lacustrine shales. The most common structural styles and hydrocarbon traps usually are associated with normal fault blocks. CAS rift basins in Chad and CAR are extensional and transtensional, and are filled by up to 7500 m of chiefly Lower Cretaceous continental clastics. The basins contain eight oil (15-39[degrees]API) and one oil and gas discovery in Lower and Upper Cretaceous sandstone reservoirs. The hydrocarbons are sourced by Lower Cretaceous shales and sealed by interbedded lacustrine and flood-plain shales. Structural styles range from simple fault blocks through complex flower structures. The main hydrocarbon traps are in contractional anticlines. Geological conditions favor the discovery of potentially commercial volumes of oil in WCARS basins, of Niger, Chad and CAR. 108 refs., 24 figs., 4 tabs.

    The pervasiveness of tenancy in the postbellum South had countervailing effects on marriage between African Americans. Tenancy placed severe constraints on African American women's ability to find independent agricultural work. Freedwomen confronted not only planters' reluctance to contract directly with women but also whites' refusal to sell land to African Americans. Marriage consequently became one of African American women's few viable routes into the agricultural labor market. We find that the more counties relied on tenant farming, the more common was marriage among their youngest and oldest African American residents. However, many freedwomen resented their subordinate status within tenant marriages. Thus, we find that tenancy contributed to union dissolution as well as union formation among freedpeople. Microdata tracing individuals' marital transitions are consistent with these county-level results.

  17. Tertiary paleomagnetism of regions around the South China Sea

    NASA Astrophysics Data System (ADS)

    Fuller, M.; Haston, R.; Lin, Jin-Lu; Richter, B.; Schmidtke, E.; Almasco, J.

    Paleomagnetic data from the Philippine Sea Plate (PSP) reveal a history of plate-wide clockwise (CW) rotation and northerly translation since the late Eocene about a nearby pole to the east. The motion has generated left lateral oblique convergence between the Philippine Sea Plate and S.E. Asia. Paleomagnetic data from Luzon in the northern Philippines show early Miocene CCW rotation followed by late Miocene CW rotation. In contrast, the Southern and Central Philippines display early Miocene CW rotation and unrotated late Miocene directions. These results define two different paleomagnetic domains with distinct post early Miocene histories. Pre-Miocene CCW rotation is suggested by data from Zambales, the Visayas and the Celebes Sea. In Borneo, a history of Tertiary CCW rotation has been found in Sarawak, and Sabah. Conflicting results have been reported from Kalimantan, some show no rotation with respect to Eurasia, while others give CCW rotations. In the Malaysian peninsula, the Segamat basalts and Kuantan dykes, of probable late Cretaceous early Tertiary age show CCW rotations similar to those seen in Sarawak. To the north peninsular Thailand, CW rotations have been found in two Miocene non-marine basins. Late Tertiary basalts from Northern and Central Thailand yield similar CW rotations while coeval flows on the Khorat plateau in Eastern Thailand are unrotated. The tectonic implications of the results remain problematical. In particular, the relative importance of true plate rotations and localized rotation of upper crustal blocks in distributed shear zones is unclear. The substantial region of CCW rotation in Borneo, the Celebes Sea and the Philippines is consistent with the broad features of the Holloway model, although the timing of the rotations precludes simple coherent rotation. The model must also be modified to include the effect of the left lateral oblique convergence between the PSP and Eurasia. The CW rotations seen in peninsular Thailand and Malaysia

    Professional psychology associations in South Africa have overtly and covertly furthered the aims of apartheid. Guidance about the ethical obligations of psychologists in the South African context has been singularly lacking, and as a result blacks have not been attracted to the profession of psychology in sufficient numbers to administer to psychological needs of the client population. The political dimension of psychological practice in South Africa needs to be addressed directly so that healing strategies relevant to the burgeoning racial conflict in South Africa can be implemented.

  1. Sexual dimorphism in cranial morphology among modern South Africans.

    2015-07-01

    Pattern expressions of morphoscopic cranial traits vary across populations with classification accuracies being highly dependent on the reference collection to which unknown skulls are compared. Despite recent developments in population-specific standards for South Africans, researchers have not addressed the accuracy of morphological methods. Several studies demonstrate differences in sexual dimorphism between South Africans and North Americans, warranting a need to re-evaluate sex estimation methods in South Africa. The purposes of this study were to test the reliability and accuracy of the Walker (2008) method and to examine patterns of sexual dimorphism among South Africans. A total of 245 modern Black and White South African male and female crania from the Pretoria Bone Collection, University of Pretoria, were scored using the Walker (2008) methodology. Cohen's kappa was used to evaluate reliability of the method, and percent correct assessed validity of the method. Logistic regression was utilised to create modified population-specific formulae. Inter- and intra-observer agreement was moderate to excellent (0.60-0.90), except for the mental eminence (0.40). The percent correct results for sex were 80% or higher for combinations of glabella, mastoid and menton and between 68% and 73% for menton, mastoid, orbital and nuchal margin using logistic equations of Walker (2008). White males had the highest (94-97%) and White females had the lowest (31-62%) percent correct. The low accuracies obtained when using Walker's (2008) equations emphasised the need for population-specific sex estimation models. Modified formulae for South Africans were created, yielding higher classification rates (84-93%) than when North American standards were employed. PMID:25394745

    2014-12-01

    This paper reports a study on South African learners' knowledge about scientific inquiry using the Views About Scientific Inquiry (VASI) Questionnaire. The sample consisted of 105 grade 11 learners from 7 schools across the socio-economic spectrum in a South African city. A rubric for scoring the VASI Questionnaire was developed and refined during the process of coding and is presented. Results showed that the learners held more informed views than that reported in previous international studies, except for particularly naive views regarding multiple methods of investigation. The results are discussed in terms of the Revised National Curriculum Statement (RNCS) that was taught from 2003 to 2010 in South African schools. This curriculum was founded on outcomes-based principles, valuing process skills rather than content. The study found that examples provided in the RNCS document correspond closely to the aspects of inquiry as described by the National Research Council. It is argued that the RNCS contributed to the more informed views about inquiry found among South African learners in this study.

    PubMed

    Carstens, Pieter; Stevens, Philip

    2016-01-01

    Historically, the link between sexual deviance and criminality has been described and documented, asserted by psychiatry, and manifested in law. Laws that have regulated sexual behaviour have referred to terms such as 'sexual deviation', 'sexual perversion' or even archaic moral terms such as 'unnatural acts and unspeakable crimes against nature'. A possible link between sexual perversion, psychopathy, and criminality, specifically manifesting in sexual homicide, has been the subject of remarkable research in forensic psychiatry. This contribution examines the phenomenon of paraphilia with specific reference to its definition, diagnostic classification and characteristics, as well as a few selections of incidences of paraphilia in South African criminal case law. A brief assessment is made of how South African criminal courts have dealt with paraphilia. In this regard, an analysis is made of the criminal liability of the paraphiliac. The South African response to sexual deviation as addressed in the Criminal Law (Sexual Offences and Related Matters) Amendment Act 32 of 2007 will also be addressed with reference to its efficacy in addressing paraphilia within South African criminal law. The interface between criminal law and medical ethics within the context of this theme will also be canvassed. In conclusion, recommendations for possible reform are canvassed. PMID:27182003

  8. RESEARCH REPORT: South African students' views of the universe

    Lemmer, M.; Lemmer, T. N.; Smit, J. J. A.

    2003-05-01

    In an empirical study the perceptions of the universe of 232 first-year Physics students from two South African universities were determined and interpreted in terms of their worldviews. The results were compared to Aristotelian and Newtonian views as well as with those of children as revealed in a literature survey. The worldviews of three non-scientific groups, namely the ancient Greeks, small children and traditional Africans are organistic in nature. The results of the empirical study showed that a statistically significant larger number of African than European students have organistic models of the universe. Since an organistic worldview differs completely from the formalized mechanistic worldview on which the classical mechanics taught at school is based, consequences for Physics education and African students are evident. This study hopes to contribute to the knowledge about the origin and features of pre-scientific conceptions and views so that they can be addressed more effectively in the science classroom.

  11. The TG/HDL-C ratio does not predict insulin resistance in overweight women of African descent: a study of South African, African American and West African women.

    Women of African descent have a high prevalence of diseases caused by insulin resistance. To positively impact cardiometabolic health in Black women, effective screening tests for insulin resistance must be identified. Recently, the TG/HDL-C ratio has been recommended as a tool to predict insulin resistance in overweight people. While the ratio predicts insulin resistance in White women, it is ineffective in African American women. As there are no data for African women, we tested the ability of the TG/HDL-C ratio to predict insulin resistance in Black women from South Africa, West Africa and the United States. For comparison, the ratio was also tested in White women from South Africa. Participants were 801 women (157 Black South African, 382 African American, 119 West African, 143 White South African, age 36 +/- 9y [mean +/- SD]). Standardized scores were created from log-transformed homeostasis model assessment-insulin resistance values from each population. Participants in the upper third of their population distribution were classified as insulin-resistant. To predict insulin resistance by the TC/HDL-C ratio, area under the receiver operating characteristic (AUC-ROC) curve was used and criteria were: 0.50 for no discrimination and > or = 0.70 for acceptable. Seventy-one percent of the Black women were overweight vs 51% of White women (P<.01). In overweight White women, AUC-ROC curve for prediction of insulin resistance by TG/HDL-C was 0.76 +/- 0.06, but below the 0.70 threshold in each group of overweight Black women (Black South African: 0.64 +/- 0.06, African American: 0.66 +/- 0.03, and West African: 0.63 +/- 0.07). Therefore, TG/HDL-C does not predict insulin resistance in overweight African American women and this investigation extends that finding to overweight Black South African and West African women. Resources to identify effective markers of insulin resistance are needed to improve cardiometabolic health in women of African descent.

    1986-01-01

    The Cretaceous-Tertiary boundary in south-central Saskatchewan is marked by coincident anomalies in abundance of iridium and fern spores at the extinction level of a suite of Cretaceous pollen taxa. Evidence of disruption of the terrestrial flora includes the fern-spore abundance anomaly and local extinction of as much as 30 percent of angiosperm species. The reorganized earliest Tertiary flora is made up largely of surviving species that assumed new roles of dominance. Persistence of climatically sensitive taxa across the boundary indicates that if paleoclimate was altered by the terminal Cretaceous event, it returned quickly to the pre-event condition.

  14. South African minerals and world demand

    van Rensburg, W.C.J.

    1983-01-01

    South Africa is a prodigious source of many mineral supplies that are critical to the industrial nations. Increasing and intensifying Soviet and Soviet-surrogate thrusts into Africa reflect a longstanding ambition to target the ''weak links'' in vulnerable Western supplies. The dangers to the Western countries relate not only to direct denial of critical resources, but to a trend toward a mineral cartel. The cessation of mineral supplies from South Africa would in most cases have a more serious effect on the availability of these commodities to the West than on their prices. A review ofpossible Soviet control and international trade developments suggests that the Western nations must consider the possible elimination of South Africa as a major supplier. 15 references, 1 figure.

  15. Living wills and advance directives in South African Law.

    2004-01-01

    The legal status of living wills and advance directives in South African Law will be considered. Presently there is no reported judgment of a court in South Africa which has directly ruled on the validity of an advance directive or living will. In a case decided in 1992 the issue as to whether to discontinue life supporting treatment was decided with reference to the legal persuasions of society and whether, in light of these, it would be reasonable to discontinue artificial feeding of the patient. The judge indicated that just as a living person has an interest in the disposal of his body so did he think that the patient's wishes as expressed when he was in good health should be given effect. In South African law every person is legally entitled to refuse medical treatment even if the consequences may be to hasten death. The South African Law Convention has extensively investigated the issue in its report entitled Report on Euthanasia and the Artificial Preservation of Life in 1998. Certain problems were identified and a draft bill was suggested.

    Diarrhoeal diseases are ranked the third major cause of childhood mortality in South African children less than 5 years, where the majority of deaths are among black children. Acute severe dehydrating rotavirus diarrhoea remains an important contributor towards childhood mortality and morbidity and has been well documented in South Africa. As the preventive strategy to control rotavirus diarrhoea, South Africa became the first country in the WHO African Region to adopt the rotavirus vaccine in the national childhood immunisation programme in August 2009. The rotavirus vaccine in use, Rotarix, GSK Biologicals, is given at 6 and 14 weeks of age, along with other vaccines as part of Expanded Programme on Immunisation (EPI). Studies which facilitated the introduction of rotavirus vaccine in South Africa included the burden of rotavirus disease and strain surveillance, economic burden of rotavirus infection and clinical trials to assess the safety and efficacy of vaccine candidates. This paper reviews the epidemiology of rotavirus in South Africa, outlines some of the steps followed to introduce rotavirus vaccine in the EPI, and highlights the early positive impact of vaccination in reducing the rotavirus burden of disease based on the post-marketing surveillance studies at Dr George Mukhari hospital, a sentinel site at University of Limpopo teaching hospital in Pretoria, South Africa, which has conducted rotavirus surveillance for >20 years.

    South Africa contains some of the world's largest mineral deposits, which include uranium. Uranium is mined as a by-product of gold production. The uranium content of the surface soil and groundwater in South Africa has been measured and shows marked variation, depending on location. Herbal remedies are collected by traditional healers from many sites, some of which may be contaminated. Thirty herbal remedies were analyzed using a sensitive adsorptive stripping voltammetry method. Eight samples had levels below the limit of detection, but in five the levels were greatly elevated, showing concentrations above 40,000 ppb. The mean uranium concentration of the remainder of the specimens was of the order of 15,000 ppb. We have attempted to put these data into context by comparison with other studies of absorption of uranium by the oral route.

  20. Embodied history. Uniqueness and exemplarity of South African AIDS.

    PubMed

    Fassin, Didier

    2002-01-01

    The exceptionality of AIDS in South Africa, both for its epidemiological features and public controversies, seems to have its correspondence in the exceptionalism of South African history, with its unprecedented regime of apartheid and its unexpected turn to democracy. The article shows that AIDS in this country can simultaneously be seen as unique (because of the historical context in which it is inscribed) and exemplar (of social determinants observed in other countries characterised by similar past or present of domination). As an alternative to cultural and behavioural models of the epidemic which have been widely spread on the African continent, the concept of embodiment of history is proposed in order to account for both the structural facts underlying the epidemic (inequality, violence, migration) and the construction of collective as well as individual narratives of the disease (including victimisation and accusation).

    1995-08-01

    For many years the South African survey system with its well monumented control beacons was the envy of many countries. The success of the integrated system plus the ease with which all types of surveys could be based on the system led to South African surveyors being referred to as fellows with 0.01 mentality. This 0.01 figure was a reference to the days prior to metrication when urban cadastral diagrams and general plans required distances to 0.01 of a foot. This historical resumé covers a period of over 100 years when surveying not only required average scientific ability but also demanded tremendous physical effort and perseverance.

    1976-12-25

    Since 1969 a survey of diving accidents involving South African amateur divers was undertaken. The South African Underwater Union diving accident report form was used, and various State agents (SA Police and inquest courts) and individual divers and club instructors were questioned. This survey covers the period up to the end of June 1976. Data acquired during the 8-year period 1969 - 1976 are compared. A conservative estimate from the number of certificates issued to club divers indicates a 25% increase in diver population, while the number of fatilities has decreased from 0,1% in 1971 to 0,016% in 1976, indicating the importance of accident reporting in determining safety trends. In general, a change in pattern is observed during the last 4 years, showing more SCUBA than breath-hold fatalities. The formation of the Decompression Sickness and Diving Accidents Investigation Panel as a further measure to decrease fatal diving accidents is discussed.

    2013-01-01

    South African youth in low-income, urbanized communities are exposed to high levels of daily stressors, which increase their risk to negative outcomes. Resiliency can provide avenues for youth to transcend adversity and may contribute to their positive development. To provide a deeper understanding of the pathways that adolescents use to overcome adversity, this paper examined future aspirations of South African youth, and how these aspirations were connected to resiliency factors framed by their lived context. A phenomenological approach was used to explore the perceptions of high school students. Fourteen focus groups with girls and boys (N=112) were conducted. Data was analyzed using a thematic approach. Discussions of the harsh conditions undermining the community’s future highlighted opportunities for improvement. Community connectedness, hope and altruism were prevalent in youth’s responses and could be used to facilitate community and individual resiliency. Our overall findings have important implications for positive youth development efforts. PMID:25897181

  5. Health and human rights in a South African bantustan.

    Turshen, M

    1986-01-01

    South Africa has stripped blacks (the majority population) of democratic rights and, over a period of 300 years, deprived them of their land; this dispossession culminated in 3.5 million involuntary removals of black South Africans to overcrowded and underdeveloped bantustans, on which a pseudo-independence is being conferred. Blacks are denationalized and disenfranchized in South Africa and their mobility is strictly controlled by the pass system, but their situation is even worse in the so-called 'homelands', where repression has replaced the rule of law. This paper presents a case study of health and human rights in the Ciskei, a bantustan that became 'independent' of South Africa in December 1981. It documents severe deprivation, widespread malnutrition and gross violations of human rights.

    Although South Africa is one of the most progressive countries in the world in terms of constitutional and legislative rights for LGBT individuals, education is one of many social arenas where these ideals are not carried out. Interviews with 25 practicing teachers revealed very little description of practice, but widely divergent understandings around sexual diversity that drew on various authoritative discourses, including religious teachings, educational policy, science, and the powerful human rights framework of the South African constitution. Implications for teacher education include directly engaging with these discourses and providing training, teaching materials, and practical guidelines based on existing policy.

    2010-01-01

    Tobacco use and its concomitant, nicotine dependence, are increasing in African countries and other parts of the developing world. However, little research has assessed nicotine dependence in South Africa or other parts of the African continent. Previous research has found that adolescent problem behaviors, including tobacco use, tend to cluster. This study examined the relationship between nicotine dependence and adolescent problem behaviors in an ethnically diverse sample of urban South African adolescents. A community sample (N = 731) consisting of “Black,” “White,” “Coloured,” and “Indian” youths aged 12–17 years was drawn from the Johannesburg metropolitan area. Structured interviews were administered by trained interviewers. Nicotine dependence was assessed by the Fagerström Test of Nicotine Dependence. Logistic regression analyses showed that higher levels of nicotine dependence significantly predicted elevated levels of violent behavior, deviant behavior, marijuana and other illegal drug use, binge drinking, early sexual intercourse, multiple sexual partners, and inconsistent condom use, despite control on the adolescents’ demographic characteristics, peer smoking, conflict with parents, peer deviance, and the availability of legal and illegal substances. These relationships were robust across ethnicity and gender. The findings indicate the need for policy makers and prevention and intervention programs in South Africa to consider adolescent nicotine dependence in conjunction with comorbid problem behaviors, including other substance use, sexual risk behaviors, and deviant behaviors.

    Summary Outcomes Extensive data from many randomised, controlled trials have shown the benefit of treating hypertension (HTN). The target blood pressure (BP) for antihypertensive management is systolic < 140 mmHg and diastolic < 90 mmHg, with minimal or no drug side effects. Lower targets are no longer recommended. The reduction of BP in the elderly should be achieved gradually over one month. Co-existent cardiovascular (CV) risk factors should also be controlled. Benefits Reduction in risk of stroke, cardiac failure, chronic kidney disease and coronary artery disease. Recommendations Correct BP measurement procedure is described. Evaluation of cardiovascular risk factors and recommendations for antihypertensive therapy are stipulated. Lifestyle modification and patient education are cornerstones of management. The major indications, precautions and contra-indications are listed for each antihypertensive drug recommended. Drug therapy for the patient with uncomplicated HTN is either mono- or combination therapy with a low-dose diuretic, calcium channel blocker (CCB) and an ACE inhibitor (ACEI) or angiotensin receptor blocker (ARB). Combination therapy should be considered ab initio if the BP is ≥ 160/100 mmHg. In black patients, either a diuretic and/or a CCB is recommended initially because the response rate is better compared to an ACEI. In resistant hypertension, add an alpha-blocker, spironolactone, vasodilator or β-blocker. Validity The guideline was developed by the Southern African Hypertension Society 2014©. PMID:25629715

    Chimere-dan, O

    1996-02-01

    This article is based on a prior report for the UN High Commissioner on Refugees on repatriation of Mozambican refugees in 1994. Official statistics revealed that 45% of all immigrants in South Africa, during 1992-94, came from European countries. 31.4% were from Asian countries and 18.4% were from African countries. Prior to about 1990, migrants tended to include contract workers recruited by big South African mining companies and other firms, or highly qualified professionals who worked in urban industrial and institutional areas. Although the number of illegal migrants from neighboring countries is not known, this population group draws the most attention. A 1993 survey of 6348 households of Mozambican refugees indicated that most left their home country due to war. Only 6.7% were economic and 2.4% were ecological migrants. Over 50% of all Mozambican refugees currently in South Africa, arrived during 1985-89. 47.2% are aged under 15 years. Refugee households average 4.38 persons/household. Household size varies with sex of the household head and area of residence. Family size was the largest in Gazankulu and the smallest in Winterveld. Family size tended to be lower among female-headed households. 79% had extended families in Mozambique. 48.3% of refugee household heads had 1-3 years of formal education, while 10.2% had none. 36.3% were unemployed and 35.1% were subsistence farmers. 89.3% wanted to return to Mozambique. National policy on migration needs to consider local needs and expectations, the economic opportunities and conditions of South Africans, and South Africa's regional position.

    We explore exhumation in the coastal Kwanza Basin by combining analyses of Tertiary hiatuses and apatite fission tracks. Planktonic biozones show five major hiatuses in the Oligo-Miocene and Plio-Pleistocene. Between gaps, Oligo-Miocene strata accumulated under marine conditions. A marine setting refutes the idea of a massively raised coastal plateau in the mid-Tertiary. Marine conditions continued until ˜5 Ma. Fission track data suggest three thermal events: ˜150 Ma, during rifting and volcanism; ˜100-70 Ma, during shortening and volcanism; and ˜20-10 Ma, during exhumation. Tertiary uplift was spatially highly variable. For the Kwanza Basin, we infer that Tertiary uplift on the West African margin is indeed a fact but that estimates of uplift timing and size are unreliable when extrapolated to adjoining areas. Massive uplift (2000-4000 m) of the Precambrian craton had little structural effect in the outer basin. Instead, minor uplifts on the shelf drove late Tertiary deformation on the slope.

    The propagation of radio signals in the Earth's atmosphere is dominantly affected by the ionosphere due to its dispersive nature. Global Positioning System (GPS) data provides relevant information that leads to the derivation of total electron content (TEC) which can be considered as the ionosphere's measure of ionisation. This paper presents part of a feasibility study for the development of a Neural Network (NN) based model for the prediction of South African GPS derived TEC. The South African GPS receiver network is operated and maintained by the Chief Directorate Surveys and Mapping (CDSM) in Cape Town, South Africa. Vertical total electron content (VTEC) was calculated for four GPS receiver stations using the Adjusted Spherical Harmonic (ASHA) model. Factors that influence TEC were then identified and used to derive input parameters for the NN. The well established factors used are seasonal variation, diurnal variation, solar activity and magnetic activity. Comparison of diurnal predicted TEC values from both the NN model and the International Reference Ionosphere (IRI-2001) with GPS TEC revealed that the IRI provides more accurate predictions than the NN model during the spring equinoxes. However, on average the NN model predicts GPS TEC more accurately than the IRI model over the GPS locations considered within South Africa.

    Sangomas or inyangas are shamans, healers, priests, and prophets that have been the backbone of Bantu communities, especially in the rural areas of Southern Africa for eons. However, with rapid Westernization and the increasing allure of the commodity market, the old ways are rapidly eroding. Indigenous knowledge has always been transmitted orally, and there is little written down about the secret traditions of initiation. Hence, the bibliography listed at the end of this article is scant. This information is a result of personal experience gleaned during my own initiation into the world of sangoma and my subsequent experiences with these healing realms. The knowledge has been gained experientially and not by the scientific method. Some of it is secret and cannot be revealed. The information may differ somewhat from healer to healer but the general principles are the same. Most sub-Saharan African peoples believe in the importance of the ancestors being able to guide events, and they revere them because they have this power. I mostly will be describing the traditions that I encountered during my initiation and subsequent practice. There are others. Since sangoma wisdom is an oral tradition the individual's initiation will depend on the mentor and the spirit guides involved. That particular sangoma's healing repertoire will be somewhat different to another though the principles remain the same. The ancestors find the most efficient way to impart the information so that the healer can do the work. The way in which they transmit the knowledge will be unique to that person's receptivity and talents. Objective proof is not part of the experiential training. In fact, any attempt at systematic inquiry gets in the way of the process. One has to put cognitive, left-brained intellect aside. Obsession with data obliterates the intuitive.

The ancestors find the most efficient way to impart the information so that the healer can do the work. The way in which they transmit the knowledge will be unique to that person's receptivity and talents. Objective proof is not part of the experiential training. In fact, any attempt at systematic inquiry gets in the way of the process. One has to put cognitive, left-brained intellect aside. Obsession with data obliterates the intuitive. The sangoma or inyanga has a lot to teach the West about the spirit world and our ancestral roots. Science has put us in touch with a

    The Shenhu Massif lies between the Zhu III Depression to the northwest, the Kaiping/Baiyun depressions to the northeast, and the Xisha Basin to the south. Major faulting began in the Paleocene, and initial basins formed on and around the Shenhu Massif during this time. Continental coarse clastics, derived from the massif area, filled the basins prior to the middle Oligocene though larger, deeper basins may have contained lacustrine environments. During the marine incursion from the middle Oligocene and until the early Miocene, coarse clastics were deposited adjacent to exposed basement areas, fine marine clastics were deposited on the massif, carbonate buildups formed along the massif rim, and carbonate platforms developed from the massif edge back into the shallow-water high-massif interior. In mid-lower Miocene, the carbonate areas were reduced in size and replaced by shales. Carbonate deposition as layers and mounds was reestablished over much of the Shenhu Massif in the early and middle Miocene. Prodelta shales in the east Shenhu Massif area and coarser clastics present in clinoforms in the Baiyun Depression are the distal components of a southerly prograding delta system located to the north. Carbonates continued to develop along the southeast side of the west Shenhu Massif during the latter part of the middle Miocene, but fine clastics dominated the rest of the area except in the Kaiping/Baiyun Depression where coarser clastics from the delta were deposited. Amoco and its partners, Nanhai West Oil Co. and Kerr-McGee Co., have begun evaluation of the Shenhu Massif area with the drilling of a Miocene carbonate buildup, the Amoco 23-1 Baodao prospect.

  18. Red Tide Strands South African Rock Lobsters

    Although some red tides form a healthy part of phytoplankton production, recurrent harmful or toxic blooms also occur, with results depending upon the type of plankton and on atmospheric and oceanic conditions. At Elands Bay in South Africa's Western Cape province, about 1000 tons of rock lobsters beached themselves during February 2002, when the decay of dense blooms of phytoplankton caused a rapid reduction in the oxygen concentration of nearshore waters. The lobsters (or crayfish, as they are known locally) moved toward the breaking surf in search of oxygen, but were stranded by the retreating tide.

    The Multi-angle Imaging SpectroRadiometer's nadir camera acquired these red, green, blue composites on February 2 and 18, 2002, during Terra orbits 11315 and 11548. The colors have been accentuated to highlight the bloom, and land and water have been enhanced separately. The two views show the shoreward migration of the algal bloom. Each image represents an area of about 205 kilometers x 330 kilometers. Elands Bay is situated near the mouth of the Doring River, about 75 kilometers northeast of the jutting Cape Columbine.

    The term 'red tide' is used to refer to a number of different types of phytoplankton blooms of various hues. The wine color of certain parts of this bloom are consistent with the ciliate species Mesodinium rubrum, which has been associated with recurring harmful algal blooms along the Western Cape coast. Under these conditions, the lobsters are not poisoned. During the recent event, government and military staff transported as many of the living lobsters as possible to areas that were less affected by the red tide. At the same time, people came from across South Africa to gather the undersized creatures for food. The effects of the losses on the maritime economy are expected to be felt over the next few years.

    The author discusses the effect of anti-apartheid actions on South Africa's position as the world's leading supplier of steam coal. Anti-apartheid economic sanctions by members of the EEC will not produce an immediate drop in tonnage because Western Europe will take coal already under contract. But Denmark and the Netherlands have already said they will phase out all contracts by 1990. Indications are that a number of other European countries will follow suit. However, it would be premature to write off South Africa as a coal trader. Ironically, economic sanctions and calls for disinvestment are likely to keep the rank weak and South African coal cheap for a long time. Cheap coal usually finds its way to market, despite political obstacles.

    Integrated algae pond systems (IAPS) combine the use of anaerobic and aerobic bioprocesses to effect sewage treatment. In the present work, the performance of IAPS was evaluated to determine the efficiency of this technology for treatment of municipal sewage under South African conditions. Composite samples were analysed over an 8 month period before and after tertiary treatment. Spectrophotometric assays indicated that the treated water from this IAPS was compliant with the discharge limits for phosphate-P, ammonium-N and nitrate/nitrite-N, and mean values were: 5.3, 2.9 and 12.4 mg L(-1), respectively. Chemical oxygen demand (COD), however, fluctuated significantly and was dependent on full function of the IAPS. Mean COD of the final treated water was 72.2 mg L(-1). Although these results suggest that the treated water discharged from this IAPS operating under South African conditions meets the standard for discharge, mean total suspended solids (TSS) was routinely above the limit at 34.5 ± 13 mg L(-1) and faecal coliforms were higher than expected. Tertiary treatment using a maturation pond series (MPS), slow sand filtration (SSF), or a controlled rock filter (CRF) ensured that the final treated water from the IAPS was of a quality suitable for discharge to the environment with CRF > SSF > MPS.

    2008-06-01

    The South African mining industry relied upon a massive African migrant workforce from the rural areas. Rural transformations in this migrant labor system form an important part of the story of developing capitalism in industrializing South Africa. Yet, recent historical studies on southern African migrant and rural wage labor have paid little attention to life adjustments made by the elderly and those 'burned out' by the mines and forced to leave formal wage employment in the urban areas. The South African segregationist state's rhetoric implied that 'retired' Africans could find economic security in their designated rural reserves. Indeed, legislation sought to prohibit Africans who were not employed from remaining in the 'white' urban areas. By the 1930s, however, the reserves were rapidly deteriorating. Many elderly Africans could not retire and were forced to seek wage labor. This raises significant questions about how retirement came to be defined and experienced by Africans in South Africa during a critical period of dramatic economic decline in the 1930s and 40s, and what the underlying material circumstances of African South Africans were with regard to adaptations to employment and ageing-related life changes. In many cases, elderly Africans were forced to forgo retirement, and find wage labor, usually in the most poorly paid, least sought-after or dangerous fields of employment. This article thus seeks to illuminate critical generational dimensions of the impact of segregation and racism in South Africa prior to the formal articulation of Apartheid.

    The natural occurrence of the carcinogenic mycotoxin ochratoxin A (OTA) in wines sold in local retail outlets in South Africa and Italy was investigated by HPLC analysis with fluorescence detection following cleanup by immunoaffinity column. All 24 local South African wines tested (15 white and 9 red) were found to contain detectable levels (>0.01 microg/L) of OTA, with a mean of 0.16 microg/L in the white wines and a mean of 0.24 microg/L in the red wines. Results were subsequently confirmed by LC-MS analysis using positive ion electrospray ionization with collision-induced dissociation of the protonated molecular ion [M + H](+) at m/z 404 and selected reaction monitoring of the resultant product ions [M + H - H(2)O - CO](+) at m/z 358 and [M + H - H(2)O](+) at m/z 386. Comparison with the fluorescence method gave a significant correlation (r = 0.87; p < 0.01). Although OTA contamination was present in all of the South African samples analyzed, levels were well below the suggested European Union limit of 0.5 microg/kg. The highest level found in a locally purchased wine was 0.39 microg/L in a blend of local and imported Spanish red wine. Of the eight Italian wines analyzed, only two red wines were contaminated above the suggested maximum level.

  7. Antimicrobial activity of selected South African medicinal plants

    2012-01-01

    Background Nearly 3,000 plant species are used as medicines in South Africa, with approximately 350 species forming the most commonly traded and used medicinal plants. In the present study, twelve South African medicinal plants were selected and tested for their antimicrobial activities against eight microbial species belonging to fungi, Mycobacteria, Gram-positive and Gram-negative bacteria. Methods The radiometric respiratory technique using the BACTEC 460 system was used for susceptibility testing against Mycobacterium tuberculosis, and the liquid micro-broth dilution was used for other antimicrobial assays. Results The results of the minimal inhibitory concentration (MIC) determinations indicated that the methanol extracts from Acacia karoo, Erythrophleum lasianthum and Salvia africana were able to prevent the growth of all the tested microorganisms. All other samples showed selective activities. MIC values below 100 μg/ml were recorded with A. karoo, C. dentate, E. lasianthum, P. obligun and S. africana on at least one of the nine tested microorganisms. The best activity (MIC value of 39.06 μg/ml) was noted with S. africana against E. coli, S. aureus and M. audouinii, and Knowltonia vesitoria against M. tuberculosis. Conclusion The overall results of the present work provide baseline information for the possible use of the studied South African plant extracts in the treatment of microbial infections.

  8. Brightness discrimination in the South African fur seal (Arctocephalus pusillus).

    Underwater, the contrast between object and background is much larger reduced with increasing distance between object and observer than in air. For marine predators, such as pinnipeds, it would therefore be advantageous to possess a high sensitivity for brightness differences, since this would increase the distance at which prey can be detected visually. Few studies have examined the brightness discrimination thresholds of pinnipeds. Two studies with phocid seals have confirmed low brightness discrimination thresholds in pinnipeds whereas the threshold obtained for the South African fur seal seems to be twice as high as that of the phocids. However, the experiments with the South African fur seal have been conducted under inadequate conditions which likely resulted in an underestimation of the brightness discrimination ability of this species. The study at hand reinvestigated the brightness discrimination threshold of the South African fur seal under well controlled conditions. In a two alternative forced choice task, one fur seal was trained to indicate the position of the brighter of two gray discs presented on a black background on a monitor. The thresholds were determined for 11 standard intensities each tested against 8 lower comparison intensities. It was found that the fur seal was able to perceive brightness differences of 8-10%, which is better than the phocid species tested so far. For low standard intensities, however, the threshold increased which could to be due to a relative slow dark adaptation rate of the fur seal. The results are discussed in terms of the relevance of visual information for pinnipeds during foraging dives and are directly compared to the results obtained for the harbor seal which has been tested under the same conditions as the fur seal in a previous study.

    Background Studies conducted in developed countries using economic models show that individual- and household- level variables are important determinants of health insurance ownership. There is however a dearth of such studies in sub-Saharan Africa. The objective of this study was to examine the relationship between health insurance ownership and the demographic, economic and educational characteristics of South African women. Methods The analysis was based on data from a cross-sectional national household sample derived from the South African Health Inequalities Survey (SANHIS). The study subjects consisted of 3,489 women, aged between 16 and 64 years. It was a non-interventional, qualitative response econometric study. The outcome measure was the probability of a respondent's ownership of a health insurance policy. Results The χ2 test for goodness of fit indicated satisfactory prediction of the estimated logit model. The coefficients of the covariates for area of residence, income, education, environment rating, age, smoking and marital status were positive, and all statistically significant at p ≤ 0.05. Women who had standard 10 education and above (secondary), high incomes and lived in affluent provinces and permanent accommodations, had a higher likelihood of being insured. Conclusion Poverty reduction programmes aimed at increasing women's incomes in poor provinces; improving living environment (e.g. potable water supplies, sanitation, electricity and housing) for women in urban informal settlements; enhancing women's access to education; reducing unemployment among women; and increasing effective coverage of family planning services, will empower South African women to reach a higher standard of living and in doing so increase their economic access to health insurance policies and the associated health services.

    The growth of technology, especially military technology, has heightened demand for certain critical mineral resources. Strategically important to the industrialized nations, these resources are increasingly available only through overseas trade. The concentration of many of these resources in politically unstable areas of the world has rendered the industrialized nations vulnerable to supply dislocation. Nowhere is this more evident than in the dependence of the United States (US) upon African minerals. This study examines these dependencies, especially with respect to South Africa's chromium and ferrochromium, in order to address the geopolitically important variables concerning resource access and the determination of US policy toward the mineral-rich region of Southern Africa.

    2003-11-01

    Inadequate data and apartheid policies have meant that, until recently, most demographers have not had the opportunity to investigate the level of, and trend in, the fertility of South African women. The 1996 South Africa Census and the 1998 Demographic and Health Survey provide the first widely available and nationally representative demographic data on South Africa since 1970. Using these data, this paper describes the South African fertility decline from 1955 to 1996. Having identified and adjusted for several errors in the 1996 Census data, the paper argues that total fertility at that time was 3.2 children per woman nationally, and 3.5 children per woman for African South Africans. These levels are lower than in any other sub-Saharan African country. We show also that fertility in South Africa has been falling since the 1960s. Thus, fertility transition predates the establishment of a family planning programme in the country in 1974.

    The eutherian placenta is considered to possess great plasticity, but it is not clear how this variation reflects adaptation to different ecological niches. Because South America was isolated for most of the Tertiary, it represents a natural laboratory to examine this question. We here describe placentation in three South American groups: Xenarthra have been part of the fauna from at least the mid-Paleocene whereas caviomorph rodents and Neotropical primates are each derived from a single founder that reached South America in the Eocene and Oligocene, respectively. The common ancestor of Xenarthra had a villous, haemochorial placenta, from which the labyrinthine, endotheliochorial placenta of sloths later evolved. Placentation in Caviomorpha follows an extraordinary stable pattern, characterized by a haemomonochorial, labyrinthine and highly lobed structure with specialized growing areas. This pattern was present before arrival of these rodents in South America and enabled a successful radiation especially during the spread of grasslands. Neotropical primates have haemochorial, trabecular placentas with a specialized maternal blood supply; a pattern that contrasts with that of Old World monkeys and may have been present in the founder generation on arrival in South America. In conclusion, there is a dichotomy within Xenarthra but otherwise the ancient South American mammals do not show much variation in principal placental characters. Thus, the successful radiation of these three groups, and their adaptation to diverse ecological niches, did not require substantial alterations in placentation.

  16. Differential opening of the Central and South Atlantic Oceans and the opening of the West African rift system

    1991-02-01

    Plate tectonic studies of the development of the Central and South Atlantic Oceans using Seasat and Geosat altimeter and magnetic anomaly isochron data now provide quantitative models of seafloor spreading through time. Such models enable an initial assessment of the differential opening between these two oceanic basins to be determined. The Equatorial Atlantic is an integral part of this oceanic rifting process, allowing stresses arising from the differential opening to be dissipated into both the Caribbean and Africa along its northern and southern boundaries respectively. The tectonic model for the West African rift system, based on geological and geophysical studies, shows a series of strike-slip fault zones diverging into Africa from the Gulf of Guinea and dissipating their shear movement into the development of extensional basins orientated perpendicular to these faults zones. The development of the West African rift system was contemporaneous with the early opening of the South Atlantic, continued to develop well after the final breakup of South America from Africa and did not cease until the late Cretaceous when there was a major phase of basin inversion and deformation. Santonian ( ~ 80 Ma) deformation across the Benue Trough (Nigeria) is broadly contemporaneous with dextral shear reactivation of the central African fracture system which, in turn resulted in renewed extension in the Sudan basins during the late Cretaceous and early Tertiary. This paper illustrates the close linkage in both time and space between the history of the African rift basins and the opening of the Atlantic. Both exhibit distinct phases of evolution with the rift basins developing in direct response to the differential opening between the Central and South Atlantic in order to dissipate stresses generated by this opening. The Mesozoic tectonic model proposed is therefore one of an intimate interaction between oceanic and continental tectonics.

    Noma (cancrum oris) is a destructive necrotising disease affecting orofacial tissues predominantly of malnourished young children. It is characterised by a rapid acute onset which usually starts in the mouth, spreads intra-orally destroying soft tissue and bone and progresses to perforate the facial skin, causing disfigurement. Polybacterial anaerobic infection is critical too, but is not alone sufficient for the initiation of noma. Cofactors, first and foremost malnutrition, but also systemic viral and bacterial infections are crucial to the development of noma. A patient with necrotising stomatitis or noma must be admitted to hospital for antibiotic treatment, fluid and electrolytes as well as nutritional supplementation and general supportive treatment. The epidemiology of noma in the South African population is unknown, and the clinicopathological features are poorly characterised. Although worldwide there is no evidence that HIV infection is a strong risk factor for noma, HIV infection may play a substantial role in the pathogenesis of noma in South Africa.

  13. Identification and characterisation of vaginal lactobacilli from South African women

    PubMed Central

    2013-01-01

    Background Bacterial vaginosis (BV), which is highly prevalent in the African population, is one of the most common vaginal syndromes affecting women in their reproductive age placing them at increased risk for sexually transmitted diseases including infection by human immunodeficiency virus-1. The vaginal microbiota of a healthy woman is often dominated by the species belonging to the genus Lactobacillus namely L. crispatus, L. gasseri, L. jensenii and L. iners, which have been extensively studied in European populations, albeit less so in South African women. In this study, we have therefore identified the vaginal Lactobacillus species in a group of 40 African women from Soweto, a township on the outskirts of Johannesburg, South Africa. Methods Identification was done by cultivating the lactobacilli on Rogosa agar, de Man-Rogosa-Sharpe (MRS) and Blood agar plates with 5% horse blood followed by sequencing of the 16S ribosomal DNA. BV was diagnosed on the basis of Nugent scores. Since some of the previous studies have shown that the lack of vaginal hydrogen peroxide (H2O2) producing lactobacilli is associated with bacterial vaginosis, the Lactobacillus isolates were also characterised for their production of H2O2. Results Cultivable Lactobacillus species were identified in 19 out of 21 women without BV, in three out of five women with intermediate microbiota and in eight out of 14 women with BV. We observed that L. crispatus, L. iners, L. jensenii, L. gasseri and L. vaginalis were the predominant species. The presence of L. crispatus was associated with normal vaginal microbiota (P = 0.024). High level of H2O2 producing lactobacilli were more often isolated from women with normal microbiota than from the women with BV, although not to a statistically significant degree (P = 0.064). Conclusion The vaginal Lactobacillus species isolated from the cohort of South African women are similar to those identified in European populations. In accordance with the other

    A culture-independent molecular analysis of archaeal communities in waters collected from deep South African gold mines was performed by performing a PCR-mediated terminal restriction fragment length polymorphism (T-RFLP) analysis of rRNA genes (rDNA) in conjunction with a sequencing analysis of archaeal rDNA clone libraries. The water samples used represented various environments, including deep fissure water, mine service water, and water from an overlying dolomite aquifer. T-RFLP analysis revealed that the ribotype distribution of archaea varied with the source of water. The archaeal communities in the deep gold mine environments exhibited great phylogenetic diversity; the majority of the members were most closely related to uncultivated species. Some archaeal rDNA clones obtained from mine service water and dolomite aquifer water samples were most closely related to environmental rDNA clones from surface soil (soil clones) and marine environments (marine group I [MGI]). Other clones exhibited intermediate phylogenetic affiliation between soil clones and MGI in the Crenarchaeota. Fissure water samples, derived from active or dormant geothermal environments, yielded archaeal sequences that exhibited novel phylogeny, including a novel lineage of Euryarchaeota. These results suggest that deep South African gold mines harbor novel archaeal communities distinct from those observed in other environments. Based on the phylogenetic analysis of archaeal strains and rDNA clones, including the newly discovered archaeal rDNA clones, the evolutionary relationship and the phylogenetic organization of the domain Archaea are reevaluated.

  15. Factors contributing to a decadal oscillation in South African rainfall

    2015-04-01

    South African rainfall in the period 1960-2010 exhibits ˜12-year oscillations of similar amplitude to those at 2-5 years. Corresponding global climate signals, as deduced from principal component analysis, include ocean heat content (HC2) and upper zonal winds (2U1) primarily in the Pacific sector. Composites of wet and dry summers are analyzed as depth and height sections to understand the ocean-atmosphere coupling that generates low frequency oscillations. Point-to-field correlations with respect to decadal-filtered South African rainfall (SA1) reveal how the Pacific signals connect with Africa through upper zonal winds, vorticity cells, sea temperature, and aerosol concentration. A regression algorithm of HC2 and 2U1 explains 58 % of the decadal SA1 variance and peak years 1976 and 2000. Although the HC2 pattern is asymmetric and independent, 2U1 principal component time scores follow the Multivariate El Nino Southern Oscillation Index and Pacific Decadal Oscillation. The conveyor of tropical easterlies that dips over the SW Indian Ocean subsequently rises over southern Africa bringing rain with a decadal frequency.

    Culture-independent molecular analysis of archaeal communities in waters collected from deep South African gold (Au) mines was performed by PCR-mediated terminal restriction fragment length polymorphism (T-RFLP) analysis of rRNA genes (rDNA) in conjunction with sequencing analysis of archaeal rDNA clone libraries. Water samples represented various environments including: deep fissure water; mine service water; and water from an overlying dolomite aquifer. T-RFLP analysis revealed that the ribotype distribution of archaea varied directly with the source of the water. The archaeal communities in the deep Au mine environments revealed a large phylogenetic diversity; the majority of members were most closely related to uncultivated species. Some archaeal rDNA clones obtained from mine service water and dolomite aquifer water samples were most closely related to the environmental rDNA clones from surface soil (Soil clones) and marine environments (Marine Group I; MGI). Other clones possessed an intermediate phylogenetic affiliation between soil clones and MGI within the Crenarchaea. Fissure water samples, derived from active or dormant geothermal environments, yielded archaeal sequences of novel phylogeny including a novel lineage of Euryarchaeota. These results suggest that deep South African Au mines harbor novel archaeal communities distinct from those observed in other environments. Based on the phylogenetic analysis of archaeal strains and rDNA clones, including these newly discovered archaeal rDNA clones, the evolutionary relationship and the phylogenetic organization of the domain Archaea is reevaluated.

  17. A reanalysis of the South African australopithecine natural endocasts.

    PubMed

    Falk, D

    1980-11-01

    Sulcal patterns of six previously available South African australopithecine natural endocasts are reexamined and compared to sulcal patterns of 17 human, 12 gorilla and six chimpanzee brains. In addition, a seventh natural endocast, from STS 58, is described for the first time and compared to an artificial endocast from the same specimen. Using the Taung endocast as a focal point, it is shown that sulcal patterns reproduced on natural endocasts of australopithecines appear to be pongid-like rather than human-like. Contrary to earlier descriptions, the lunate sulcus occupies a rostral position similar to that found in pongids. Since South African australopithecine brains do not appear to be reorganized along human lines at a gross external neuroanatomical level, the concept of neurological reorganization is best applied at finer neurological levels, perhaps at the level of the neuron or at a neurochemical level. Thus, future studies by comparative neuroscientists are more likely to elucidate the fine details of neurological reorganization that occurred during early human evolution than are studies by paleontologists who directly observe the australopithecine fossil record of natural endocasts.

    The technique of Raman spectroscopy was used to examine the composition of ancient African domestic clay pottery of South African origin. One sample from each of four archaeological sites including Rooiwal, Lydenburg, Makahane and Graskop was studied. Normal dispersive Raman spectroscopy was found to be the most effective analytical technique in this study. XRF, XRD and FT-IR spectroscopy were used as complementary techniques. All representative samples contained common features, which were characterised by kaolin (Al 2Si 2O 5(OH) 5), illite (KAl 4(Si 7AlO 20)(OH) 4), feldspar (K- and NaAlSi 3O 8), quartz (α-SiO 2), hematite (α-Fe 2O 3), montmorillonite (Mg 3(Si,Al) 4(OH) 2·4.5H 2O[Mg] 0.35), and calcium silicate (CaSiO 3). Gypsum (CaSO 4·2H 2O) and calcium carbonates (most likely calcite, CaCO 3) were detected by Raman spectroscopy in Lydenburg, Makahane and Graskop shards. Amorphous carbon (with accompanying phosphates) was observed in the Raman spectra of Lydenburg, Rooiwal and Makahane shards, while rutile (TiO 2) appeared only in Makahane shard. The Raman spectra of Lydenburg and Rooiwal shards further showed the presence of anhydrite (CaSO 4). The results showed that South African potters used a mixture of clays as raw materials. The firing temperature for most samples did not exceed 800 °C, which suggests the use of open fire. The reddish brown and grayish black colours were likely due to hematite and amorphous carbon, respectively.

    Recent scholarly attention has focused on weak governance and the negative effects of corruption on the provision of health services. Employing agency theory, this article discusses corruption in the South African health sector. We used a combination of research methods and triangulated data from three sources: Auditor-General of South Africa reports for each province covering a 9-year period; 13 semi-structured interviews with health sector key informants and a content analysis of print media reports covering a 3-year period. Findings from the Auditor-General reports showed a worsening trend in audit outcomes with marked variation across the nine provinces. Key-informants indicated that corruption has a negative effect on patient care and the morale of healthcare workers. The majority of the print media reports on corruption concerned the public health sector (63%) and involved provincial health departments (45%). Characteristics and complexity of the public health sector may increase its vulnerability to corruption, but the private-public binary constitutes a false dichotomy as corruption often involves agents from both sectors. Notwithstanding the lack of global validated indicators to measure corruption, our findings suggest that corruption is a problem in the South African healthcare sector. Corruption is influenced by adverse agent selection, lack of mechanisms to detect corruption and a failure to sanction those involved in corrupt activities. We conclude that appropriate legislation is a necessary, but not sufficient intervention to reduce corruption. We propose that mechanisms to reduce corruption must include the political will to run corruption-free health services, effective government to enforce laws, appropriate systems, and citizen involvement and advocacy to hold public officials accountable. Importantly, the institutionalization of a functional bureaucracy and public servants with the right skills, competencies, ethics and value systems and whose

    This random survey was to determine the flexible nasopharyngoscope disinfection practice employed by South African otolaryngologists and to establish whether a breach in the disinfection process exists. The study also aimed to identify organisms most likely to be transmitted via endoscopy and to propose a protocol for the disinfection of the flexible nasopharyngoscope. A questionnaire regarding disinfection techniques used for the flexible nasopharyngoscope was sent to 90 otolaryngologists in South Africa. All provinces were equally represented in the survey. Forty-five otolaryngologists out of a total of 90 participated in the study. Many of the otolaryngologists had no access to a flexible nasopharyngoscope and were therefore not included in the study. Fewer than 50 per cent of the 45 surgeons washed the instrument with soap/detergent and water after use. Only 42 per cent of surgeons used a FDA-approved disinfectant, 52 per cent of which immersed the scope for a shorter period than the recommended contact time. Of the 58 per cent using non-FDA-approved products, 33 per cent used only a 70 per cent Isopropyl alcohol wipe, without immersion of the scope in disinfectant solution. The remaining 25 per cent used non-FDA-approved disinfectants either by wiping or limited immersion of the scope. Of the 45 surgeons, 49 per cent used a different method of disinfection for high-risk patients. Strict guidelines have been proposed for the disinfection of this semi-critical device by the Association of Professionals for Infection Control (APIC) and the Centers for Disease Control (CDC). These guidelines are currently not being followed by many South African otolaryngologists. There is therefore a real risk of transmitting infectious diseases, especially tuberculosis, via endoscopy.

  4. Understandings of gender and HIV in the South African media.

    PubMed

    Gibbs, Andrew

    2010-01-01

    It is widely agreed empowering women to take control of their lives and sexual health is a key strategy for tackling gender inequalities and HIV/AIDS, but to date this has been exceedingly difficult to achieve. This paper explores how a sample of South African media represent the relationship between gender and HIV/AIDS in the interests of understanding the symbolic context in which HIV/AIDS programmers conduct their work. The starting assumption is that representations of gender and HIV in the symbolic sphere provide the context within which people charged with designing and implementing women's empowerment interventions--government officials and NGO programme managers--construct understandings of this relationship and how best to tackle it. Content analysis was conducted on four South African newspapers between 1 January 2007 and 31 December 2008. Newspapers selected are widely read by "opinion leaders"; government officials and NGO programme managers. It is accepted that women's empowerment needs to involve top-down and bottom-up approaches. Dominant media representations portray women's empowerment as almost entirely a top-down process in which powerful actors are responsible for identifying and implementing women-focused interventions. Newspapers pay little attention to the need for the mobilisation of women via bottom-up programmes. Furthermore, while the media focuses on structural- and individual-level interventions, there is limited discussion of the importance of community-development interventions. Community-development interventions emphasise the need to build and support community-led responses to HIV. For women's empowerment to be successful interventions need to be at all levels. Currently, much emphasis is placed on the need for "socially responsible" media reporting in South Africa that supports positive social development and social justice. Against this background, we conclude media representations of appropriate ways to tackle gender and HIV

    Background Some smokeless tobacco products (SLT) have been shown to be associated with only a fraction of the risks of cigarettes. This study assessed South African smokers’ interest in switching to a hypothetical reduced harm SLT product. Methods The 2007 South African Social Attitudes Survey was analysed for 678 exclusive cigarette smokers. Respondents were asked about their perceptions about relative harm of snuff compared to cigarettes, and their interest in switching to snuff if informed it was 99% less harmful than cigarettes. Results About 49.7% of exclusive cigarette smokers believed that snuff was equally as harmful as cigarettes; 12.9% thought snuff was more harmful; 5.7% thought snuff was less harmful; while 31.8% did not know if there was a difference in harm between snuff and cigarettes. Approximately 24.2% of exclusive cigarette smokers indicated interest in switching to snuff, with significantly greater interest observed among those exposed to 100% smoke-free work environment. Interest in switching was highest (34.7%) among smokers who believed a priori that using snuff was more harmful than cigarettes, and lowest (14.5%) among those who did not know if there was a difference in harm. In a multi-variable adjusted logistic regression model, this latter group remained less likely to be interested in harm reduction switching (adjusted odds ratio = 0.42; 95% CI: 0.19–0.91). Conclusion About a quarter of smokers indicated interest in harm reduction switching to snuff. SLT products have a potential role in reducing the harm from smoking in South Africa, but only if they are not used to circumvent smoke-free laws that have been associated with reduced smoking.

    Background South Africa has a significant violence problem. The exposure of girls and women to interpersonal violence is widespread, and the victimization of men, especially to severe and homicidal forms of aggression, is of considerable concern, with male homicide eight times the global rate. In the last two decades, there have been a plethora of South African policies to promote safety. However, indications suggest that the policy response to violence is not coherently formulated, comprehensive, or evenly implemented. Objective This study examines selected South African national legislative instruments in terms of their framing and definition of violence and its typology, vulnerable populations, and prevention. Design This study comprises a directed content analysis of selected legislative documents from South African ministries mandated to prevent violence and its consequences or tasked with the prevention of key contributors to violence. Documents were selected using an electronic keyword search method and analyzed independently by two researchers. Results The legislative documents recognized the high levels of violence, confirmed the prioritization of selected vulnerable groups, especially women, children, disabled persons, and rural populations, and above all drew on criminological perspectives to emphasize tertiary prevention interventions. There is a policy focus on the protection and support of victims and the prosecution of perpetrators, but near absent recognition of men as victims. Conclusions There is a need to broaden the policy framework from primarily criminological and prosecutorial perspectives to include public health contributions. It is likewise important to enlarge the conceptions of vulnerability to include men alongside other vulnerable groups. These measures are important for shaping and resourcing prevention decisions and strengthening primary prevention approaches to violence. PMID:26228996

    This article reports on an exploratory investigation carried out to identify conceptions of some components of worldview, based on logicostructural worldview theory, held by science student teachers in a South African context. It explores relationships among worldviews, student characteristics, and scientific concepts. The sample included 48 final-year science student teachers. Data were gathered by a questionnaire with follow-up interviews. Questions were based on Kearney's model of worldview with stimulus items related to each of seven worldview categories. Responses were categorized and examined for possible relationships. Results of the investigation indicated that students' conceptions of time and distance were nonmechanistic and psychologically bound and that authoritarian scientific explanation was considered as sufficient for proof. Some significant relationships were found between items as well as between field of study and scientific conceptions.Received: 30 March 1994; Revised: 1 December 1994;

    A 14-year-old female South African fur seal (Arctocephalus pusillus) was presented with a large skin mass on the right shoulder. At necropsy examination, multiple white nodules were found in the lungs, liver, spleen and right axillary lymph nodes. Histologically, the skin mass was composed of round to polygonal neoplastic cells with round to oval nuclei and variably sized cytoplasmic vacuoles. Cellular and nuclear atypia were prominent. Immunohistochemically, the neoplastic cells expressed vimentin, but not cytokeratins, S100 protein, adipophilin or desmin. The cytoplasmic lipid droplets stained positively with oil red O. Metastasis was seen in the lungs, liver, spleen and right axillary lymph nodes, with similar morphological features to the skin mass. Based on these findings, a diagnosis of a pleomorphic liposarcoma with systemic metastasis was made. No previous reports of metastatic liposarcomas have been published in marine mammals.

  12. Prevention implications of AIDS discourses among South African women.

    Strebel, A

    1996-08-01

    Social constructionist and feminist analyses have done much to extend the understanding of AIDS beyond the biomedical to include social accounts of the constitution of AIDS knowledge and meanings. However, these frameworks have not translated easily into realistic responses to the paradox of women being seen as responsible for HIV prevention, while they lack the power to implement safe sex behavior. This study explores the range and interplay of discursive themes which South African women drew on regarding AIDS and identifies constraints and opportunities for realistic prevention. The research involved 14 focus group discussions with women. Two main interpretative repertoires regarding AIDS were identified from the texts: one concerning the medicalization and the other the stigmatization of the disease. Although these representations were not unchallenged, the pervasive sense was of denial of own risk, fear, and fatalism. However, the analysis highlighted the complexity of issues to be faced in developing effective prevention initiatives.

    A telephone survey was conducted to compare the extent of smokeless tobacco use and perception of related health risks by white and black urban South Africans. Using systematic random sampling, one out of every 20 phone numbers was selected from the Seshego (blacks) and Pietersburg (whites) telephone directory until 300 tobacco users in each site were identified. Among the white group, cigarette smoking was clearly predominant (290) and only 10 used snuff, whereas among the black sample almost half (46.7%) of the tobacco users used snuff, especially women (40%). Although a majority acknowledged negative effects of snuff use on their health and its addictive character, 42% either do not believe or do not know that snuff contains nicotine and causes cancer.

    A 14-year-old female South African fur seal (Arctocephalus pusillus) was presented with a large skin mass on the right shoulder. At necropsy examination, multiple white nodules were found in the lungs, liver, spleen and right axillary lymph nodes. Histologically, the skin mass was composed of round to polygonal neoplastic cells with round to oval nuclei and variably sized cytoplasmic vacuoles. Cellular and nuclear atypia were prominent. Immunohistochemically, the neoplastic cells expressed vimentin, but not cytokeratins, S100 protein, adipophilin or desmin. The cytoplasmic lipid droplets stained positively with oil red O. Metastasis was seen in the lungs, liver, spleen and right axillary lymph nodes, with similar morphological features to the skin mass. Based on these findings, a diagnosis of a pleomorphic liposarcoma with systemic metastasis was made. No previous reports of metastatic liposarcomas have been published in marine mammals.

    A national multicenter study identified 17 South African children with vertically acquired HIV-1 infection and HIV-associated vasculopathy. Five of the children (all indigenous African ancestry) had progressive vascular disease, consistent with moyamoya syndrome. Median presentation age 5.8 years (range 2.2-11). The children with moyamoya syndrome presented with abnormal CD4 counts and raised viral loads. Clinical features included motor deficits, neuroregression, and intellectual disability. Neuroimaging supported progressive vascular disease with preceding clinically silent disease course. Neurologic recovery occurred in 1 patient with improved CD4 counts. Four of the 5 children presented during the era when access to antiretroviral therapy was limited, suggesting that with improved management of HIV-1, progressive vasculopathy is less prevalent. However the insidious disease course illustrated indicates that the syndrome can progress "silently," and manifest with misleading phenotypes such as cognitive delay or regression. Sub-Saharan Africa has limited access to neuroimaging and affected children may be underdiagnosed. PMID:26961262

    In 1984-1985, prevalences of appendectomy in inter-ethnic series of South African school pupils of 16-18 yr were: rural blacks, 0.5%; urban blacks, 1.0%; Indians, 2.6%; coloreds (Eur-African-Malay), 2.2%; Afrikaans whites, 13.4%; and English whites, 9.9%. Corresponding respective annual incidences per 1000 pupils of 10-19 yr were: 0.3, 0.6, 1.9, 1.7, 9.8, and 7.8. Thus, appendectomy is rare or infrequent in all except the white populations. Peak occurrence was postpubertal. There was no consistent sex bias. Dietarily, mean daily fiber intake was relatively low in all groups, 17.9-26.1 g. While the percentage of energy from fat intake was low in blacks, 16.3-22.3%, it was much higher in the other populations, 32.7-39.5%. Clearly, factors other than diet are involved in regulating frequency of appendectomy. While mortality is negligible and morbidity slight, elucidation of causation and prevention of the disease is desirable since subsequently appendectomy patients are at greater than average risk to certain cancers.

    Studies of dose-response relationships between respiratory outcomes at autopsy and coal dust exposure are limited. The Pathology Automation System (PATHAUT) database of South African miners, is one of the largest autopsy databases of occupational lung disease. This study described the prevalence of respiratory outcomes among South African coal miners at autopsy, and determined whether dose response relationships existed between emphysema and exposure. Autopsies conducted from 1975 to 1997 on coal miners with exclusive coal mining exposure and having exposure duration information (n = 3,167) were analyzed from PATHAUT Logistic regression was used to determine relationships between exposure and outcomes, controlling for race, smoking and age on a subset for whom smoking history was available (n = 725). The prevalence of silicosis, tuberculosis (TB), coal workers' pneumoconiosis (CWP), and moderate and marked emphysema were 10.7%, 5.2%, 7.3%, and 64%, respectively. All diseases, except TB, were associated with exposure duration. Black miners had 8.3 and 1.2 fold greater risks for TB and CWP, respectively, than white miners. White miners had an increased risk of 1.4 and 5.4 for silicosis and moderate to marked emphysema, respectively. In models unadjusted for age, and including smoking, moderate to marked emphysema was strongly associated with exposure duration (OR = 3.4; 95% CI = 1.9-5.9 for highest tercile of exposure duration). Exposure-related risk estimates were reduced when age was introduced into the model. However age and duration of exposure were highly correlated, = 0. 68) suggesting a dilution of the exposure effect by age. There were significant dose related associations of disease, including emphysema, with coal dust exposure.

    Rationale: HIV-associated tuberculosis remains a major health problem among the gold-mining workforce in South Africa. We postulate that high levels of recent transmission, indicated by strain clustering, are fueling the tuberculosis epidemic among gold miners. Objectives: To combine molecular and epidemiologic data to describe Mycobacterium tuberculosis genetic diversity, estimate levels of transmission, and examine risk factors for clustering. Methods: We conducted a cross-sectional study of culture-positive M. tuberculosis isolates in 15 gold mine shafts across three provinces in South Africa. All isolates were subject IS6110-based restriction fragment length polymorphisms, and we performed spoligotyping analysis and combined it with basic demographic and clinical information. Measurements and Main Results: Of the 1,602 M. tuberculosis patient isolates, 1,240 (78%) had genotyping data available for analysis. A highly diverse bacillary population was identified, comprising a total of 730 discrete genotypes. Four genotypic families (Latin American Mediterranean spoligotype family; W-Beijing; AH or X; and T1–T4) accounted for over 50% of all strains. Overall, 45% (560/1,240) of strains were genotypically clustered. The minimum estimate for recent transmission (n − 1 method) was 32% (range, 27–34%). There were no individual-level risk factors for clustering, apart from borderline evidence for being non–South African and having self-reported HIV infection. Conclusions: The high M. tuberculosis genetic diversity and lack of risk factors for clustering are indicative of a universal risk for disease among gold miners and likely mixing with nonmining populations. Our results underscore the urgent need to intensify interventions to interrupt transmission across the entire gold-mining workforce in South Africa. PMID:25419914

  19. East African and Kuunga Orogenies in Tanzania - South Kenya

    Tanzania and southern Kenya hold a key position for reconstructing Gondwana consolidation because here different orogen belts with different tectonic styles interfere. The older, ca. 650-620 Ma East African Orogeny resulted from the amalgamation of arc terranes in the northern Arabian-Nubian Shield (ANS) and continental collision between East African pieces and parts of the Azania terrane in the south (Collins and Pisarevsky, 2005). The change form arc suturing to continental collision settings is found in southern Kenya where southernmost arcs of the ANS conjoin with thickened continental margin suites of the Eastern Granulite Belt. The younger ca. 570-530 Ma Kuunga orogeny heads from the Damara - Zambesi - Irumide Belts (De Waele et al., 2006) over Tanzania - Mozambique to southern India and clashes with the East African orogen in southern-central Tanzania. Two transitional orogen settings may be defined, (1) that between island arcs and inverted passive continental margin within the East African Orogen and, (2) that between N-S trending East African and W-E trending Kuungan orogenies. The Neoproterozoic island arc suites of SE-Kenya are exposed as a narrow stripe between western Azania and the Eastern Granulite belt. This suture is a steep, NNW stretched belt that aligns roughly with the prominent southern ANS shear zones that converge at the southern tip of the ANS (Athi and Aswa shear zones). Oblique convergence resulted in low-vorticity sinstral shear during early phases of deformation. Syn-magmatic and syn-tectonic textures are compatible with deformation at granulite metamorphic conditions and rocks exhumed quickly during ongoing transcurrent motion. The belt is typified as wrench tectonic belt with horizontal northwards flow of rocks within deeper portions of an island arc. The adjacent Eastern Granulite Nappe experienced westward directed, subhorizontal, low-vorticity, high temperature flow at partly extreme metamorphic conditions (900°C, 1.2 to 1.4 GPa

    The inauguration of the Southern African Large Telescope (SALT) is an auspicious moment for reflection on South African astronomical history, the manner in which this heritage has been represented in the past, and how it might best be represented in the future. It is now appropriate to reassess the history of Euro pean astronomy in South Africa, confronting rather than ignoring issues of national identity, scientific politics, and racism. There are also wide opportunities for scholarship on South African archaeoastronomy and indigenous knowledge systems, with potential applications to culturally relevant basic science education. In the case of astronomy, reconciliation to a rich if troubled history will only come to pass when the science is not only pursued in South Africa, but when its heritage pertains to all South Africans.

    In spite of sustained efforts tertiary institutions implement to try and improve student academic performance, the number of students succeeding in first-year mathematics courses remains disturbingly low. For most students, the gap between their mathematical capability and the competencies they are expected and need to develop to function effectively in these courses persists even after course instruction. In this study, an instrument for identifying and examining factors affecting student performance and success in a first-year Mathematics university course was developed and administered to 86 students. The overall Cronbach's Alpha coefficient for the questionnaire was found to be 0.916. Having identified variables from prior research known to affect student performance, factor analysis was used to identify variables exhibiting the greatest impact on student performance. The variables included prior academic knowledge, workload, student approaches to learning, assessment, student support teaching quality, methods and resources. From the analysis, students' perceptions of their workload emerged as the factor having the greatest impact on student's performance, followed by the matriculation examination score. The findings are discussed and strategies that can be used to improve teaching and contribute to student success in a first-year mathematics course in a South African context are presented.

    In this concatenated overview, the development of psychology in South Africa is traced from its origins in the late 19th century to the present. The seminal influences on the science and practice of psychology of the racialized polity and the responses to the prevailing regimen are also explored. The significant events in the patinated layers of psychological discourse and consequent policies in these constrained circumstances are traversed. Despite the nonracial era occasioned by the formation of the Psychological Society of South Africa three months before the advent of democracy under Nelson Mandela in 1994, the profession of psychology remains demographically skewed. Nevertheless, psychology in the current democratic dispensation enjoys a high profile and is actively engaged in ongoing and reflexive self-examination to ensure that it is more accessible and truly serves humanity. If Africa is psychology's last frontier, the critical denouement of the various issues confronting psychology in the southern tip of the African continent will provide a positive growth path that is likely to merit attention beyond its borders.

    The adverse effects of acne on the psyche have been established in patients from 'first world' countries. There has been no in depth study in predominantly black patients from Africa addressing this issue. This was a prospective cross-sectional study of acne patients attending a dermatology unit in KwaZulu-Natal, South Africa. A questionnaire was completed and acne graded by the Global Acne Grading scale. Psychological morbidity and quality of life (QOL) were assessed by the General Health Questionnaire and Dermatology Specific Quality of Life Questionnaires, respectively. We found that clinical severity was not associated with patient perception or psychological distress. The QOL measures such as feelings, social activities, performance at work or school, activities of daily living and overall mental health were found to be associated with distress with associated P-values of 0.0002, 0.0168, 0.0032, 0.033 and < 0.0001, respectively. The severity of acne was not associated with psychological distress. Painful and bleeding lesions were associated with distress levels; P = 0.042 and P = 0.019, respectively. In conclusion, South African patients with acne vulgaris suffer significant psychological distress, which affects the quality of their lives. PMID:15663491

    When a mine in South Africa is granted a closure certificate, the responsibility for possible residual environmental impacts is passed from owners of the mine to the state. To enable the closure process to be completed with expediency and to ensure that industry fulfils their environmental obligations, the South African coal mining industry has initiated a research project to identify the problems that could be barriers to preventing successful mine closure. This paper describes the results of the investigation which was carried out together with mine owners and involved governmental departments. The results indicate that the problems that are presently being experienced are diverse and complex in nature. The identified problems range from a lack of well defined procedures and information to inadequate technical solutions. The lack of information on which to base longer term predictions and financial provisions is also seen to be a serious problem. By assessing the problems and the factors that cause them, areas of focus for further research have been identified. These areas include aspects such as the establishment of information bases, research projects to develop mitigation technologies and the establishment of guidelines and informatory processes to assist mine staff with closure of mines.

    Trauma in South Africa has been termed the malignant epidemic. This heritage was the result of a violent colonial legacy which spawned the apartheid system of injustice and the struggle against it The Apartheid regime created overcrowding, unemployment, social stagnation, and the disruption of normal family life. These were the catalysts for the incredible amount of criminal and interpersonal conflict in South Africa over the last 50 years. African townships such as Soweto in Johannesburg and Umlazi in Durban were crime-ridden ghettoes where the apartheid police were more interested in fueling the "black on black" violence rather than trying to curb it. Baragwanath (Chris Hani-Baragwanath) and King Edward the VIII Hospital in Durban were the "trauma care epicenters" on the fringes of these huge urban conurbations. Both were designated black hospitals and both were underfunded and dilapidated. Even the architecture was similar, with prefabricated, poorly ventilated structures serving as wards and clinics in both institutions. Trauma volumes consisted of between 10 and 20 laparotomies on weekend nights at the height of political unrest. This led to vast individual experience in several areas of trauma typified by Demetriades' experience with 70 penetrating cardiac injuries. In this setting of limited resources and an overwhelming volume of trauma, selective conservatism as a surgical philosophy took root and has profoundly influenced the way the world manages trauma. We detail and illustrate the evolution of this approach and its continued application. PMID:15983718

    2016-01-01

    Our daily lives are influenced by three different daily timers: the solar clock, our endogenous circadian clock and the societal clock. The way an individual's endogenous clock synchronises to the solar clock, through either advances or delays relative to sunrise and sunset, results in a phenomenon known as diurnal preference or chronotype. South Africa uses just one time zone, but in the most easterly regions of the country, the sun rises and sets up to an hour earlier than in the most westerly regions throughout the year. It was hypothesised first that South Africans living in the east of the country may have a greater preference for mornings (more morning chronotypes) than those living in the west; and second, that this difference would not be due to genetic differences in the populations, particularly a genetic polymorphism previously shown to influence chronotype. Here, we describe and compare the distribution of chorotype and PERIOD3 variable number tandem repeat (VNTR) polymorphism frequency in eastern (n = 129) and western (n = 175) sample populations. Using the Horne-Östberg Morningness, Eveningness Questionnaire we found that there was a significantly higher proportion of morning-types in the eastern population (56.6%) than in the western population (39.4%), and there were higher proportions of neither-types and evening-types in the western population (51.4% and 9.1%, respectively) than in the eastern population (37.2% and 6.2%, respectively) (p = 0.009). There were no significant differences in distribution of the PER3 genotype (p = 0.895) and allele (p = 0.636) frequencies. Although previous studies have shown associations between chronotype and PER3 VNTR genotypes, no significant associations were observed in either the eastern (p = 0.695) or the western (p = 0.630) populations. These findings indicate that, in South African populations, longitude influences chronotype independently of PER3 genotype. The impacts of the differences in chronotype whilst

    2008-01-01

    Background Tropical rain forests are the most diverse terrestrial ecosystems on the planet. How this diversity evolved remains largely unexplained. In Africa, rain forests are situated in two geographically isolated regions: the West-Central Guineo-Congolian region and the coastal and montane regions of East Africa. These regions have strong floristic affinities with each other, suggesting a former connection via an Eocene pan-African rain forest. High levels of endemism observed in both regions have been hypothesized to be the result of either 1) a single break-up followed by a long isolation or 2) multiple fragmentation and reconnection since the Oligocene. To test these hypotheses the evolutionary history of endemic taxa within a rain forest restricted African lineage of the plant family Annonaceae was studied. Molecular phylogenies and divergence dates were estimated using a Bayesian relaxed uncorrelated molecular clock assumption accounting for both calibration and phylogenetic uncertainties. Results Our results provide strong evidence that East African endemic lineages of Annonaceae have multiple origins dated to significantly different times spanning the Oligocene and Miocene epochs. Moreover, these successive origins (c. 33, 16 and 8 million years – Myr) coincide with known periods of aridification and geological activity in Africa that would have recurrently isolated the Guineo-Congolian rain forest from the East African one. All East African taxa were found to have diversified prior to Pleistocene times. Conclusion Molecular phylogenetic dating analyses of this large pan-African clade of Annonaceae unravels an interesting pattern of diversification for rain forest restricted trees co-occurring in West/Central and East African rain forests. Our results suggest that repeated reconnections between the West/Central and East African rain forest blocks allowed for biotic exchange while the break-ups induced speciation via vicariance, enhancing the levels of

    South Africa (SA) has had great success in creating major astronomical facilities - SALT, KAT and MeerKAT. However, the existing SA astronomical community is almost entirely white. The lack of black scientists (80% of SA population is black) is obviously one of the many legacies of apartheid and a major initiative was required to rectify the situation. The National Astrophysics and Space Science Program (NASSP) is aimed at ensuring the development of high level physics skills within SA, and specifically takes graduates with bachelor's degrees in math or the physical sciences and prepares them to do PhDs in astrophysics and related disciplines. However, in 2003 when NASSP was established, there were no black SA astronomers, who could act as role models and mentors. This jeopardized the chances of success of NASSP and with it astronomy in SA. An American organization, the National Society of Black Physicists (NSBP) received a $355,000 grant from the WK Kellogg Foundation to increase the number of black SA astronomers. It enabled African American scientists - both professionals and students - to participate in NASSP. The African American professionals taught NASSP courses and acted as role models and mentors. The project was an overwhelming success. From its beginning in 2003, the NASSP honors program graduates have gone on to a Master's or PhD program at a rate of 60% (USA rate: 35%). American participation started in 2008. In the very next year the number of black students jumped dramatically, reaching 80% in 2013 and this level continued in 2010-2014. We believe this increase and its maintenance is in large part due to bringing black SA students from SA historically black colleges for two weeks to expose them to astronomy, to a one year program to allow them to catch up academically and to the mentoring activities of the members of NSBP.

  1. Colonialism, Biko and AIDS: reflections on the principle of beneficence in South African medical ethics.

    PubMed

    Braude, Hillel David

    2009-06-01

    This paper examines the principle of beneficence in the light of moral and epistemological concerns that have crystallized in the South African context around clinical care. Three examples from the South African experience affecting the development of bioethics are examined: medical colonialism, the death in detention of Steve Biko, and the HIV/AIDS epidemic. Michael Gelfand's book [(1948). The sick African: a clinical study. Cape Town: Stewart Printing Company.] on African medical conditions captures the ambiguous nature of colonial medicine that linked genuine medical treatment with the civilizing mission. Biko's death was a key historical event that deeply implicated the medical profession under apartheid. The present HIV/AIDS epidemic presents the gravest social and political crisis for South African society. All three experiences influence the meaning and relevance of beneficence as a bioethics principle in the South African context. This paper argues for a South African bioethics informed by a critical humanism that takes account of the colonial past, and that does not model itself on an "original wound" or negation, but on positive care-giving practices.

    Tuberculosis, caused by Mycobacterium bovis, was first diagnosed in African buffalo in South Africa's Kruger National Park in 1990. Over the past 15 years the disease has spread northwards leaving only the most northern buffalo herds unaffected. Evidence suggests that 10 other small and large mammalian species, including large predators, are spillover hosts. Wildlife tuberculosis has also been diagnosed in several adjacent private game reserves and in the Hluhluwe-iMfolozi Park, the third largest game reserve in South Africa. The tuberculosis epidemic has a number of implications, for which the full effect of some might only be seen in the long-term. Potential negative long-term effects on the population dynamics of certain social animal species and the direct threat for the survival of endangered species pose particular problems for wildlife conservationists. On the other hand, the risk of spillover infection to neighboring communal cattle raises concerns about human health at the wildlife-livestock-human interface, not only along the western boundary of Kruger National Park, but also with regards to the joint development of the Greater Limpopo Transfrontier Conservation Area with Zimbabwe and Mozambique. From an economic point of view, wildlife tuberculosis has resulted in national and international trade restrictions for affected species. The lack of diagnostic tools for most species and the absence of an effective vaccine make it currently impossible to contain and control this disease within an infected free-ranging ecosystem. Veterinary researchers and policy-makers have recognized the need to intensify research on this disease and the need to develop tools for control, initially targeting buffalo and lion. ?? 2005 Elsevier B.V.

  4. South African managers in public service: On being authentic

    2014-01-01

    South African managers in public service consistently face challenges related to managing a well-adjusted and productive diverse workforce. Following the notion that leadership authenticity fosters positive psychological employee capacity, the aim of this study was to explore the meaning essence of authenticity as lived in the work–life experiences of senior managers in public service. Five senior managers in public service were purposefully selected based on their articulated challenges with being authentic at work, whilst attending a diversity sensitivity workshop. From a hermeneutic phenomenological perspective, in-depth interviews were used, and an interpretative phenomenological analysis yielded two predominant themes offering a description of what it means to be authentic. Authenticity is experienced as an affective state that results from a continuous self-appraisal of the extent to which expression of self is congruent with a subjective and socially constructed expectation of self in relation to others. Authenticity seems to develop through a continuous process of internal and external adaptation, and it leads to ultimately building a differentiated yet integrated identity of self. A reciprocal dynamic between feeling authentic and self-confidence alludes to the potential importance of authenticity dynamics in identity work. PMID:24434054

    Setting The “Thibela TB” cluster randomised trial of community-wide isoniazid preventive therapy (IPT) to reduce tuberculosis incidence in the South African gold mines. Objectives To determine the proportion of participants eligible for IPT and the reasons and risk factors for ineligibility, to inform the scale-up of IPT. Design Cross-sectional survey of participants in intervention clusters (mine shafts) consenting to tuberculosis screening and assessment for eligibility to start IPT. Results Among 27,126 consenting participants, 94.7% were male, the median age was 41 years, 12.2% reported previous tuberculosis, 0.6% reported ever taking IPT and 2.5% reported currently taking antiretroviral therapy. There were 24,430 (90.1%) assessed as eligible to start IPT, of whom 23,659 started IPT. The most common reasons for ineligibility were having suspected tuberculosis that was subsequently confirmed by a positive smear and/or culture (n=705), excessive alcohol consumption (n=427) and being on tuberculosis treatment at time of initial screen (n=241). Ineligibility was associated with factors including older age, female gender, prior history of tuberculosis and being in “HIV care”. However, at least 78% were eligible for IPT in all of these sub-groups. Conclusions The vast majority of participants in this community-wide intervention were eligible for IPT. PMID:24244741

  6. IYA2009 in Africa: A South African perspective

    2008-06-01

    In Africa the stars have always been a part of people's everyday lives, be it in the form of folklore, superstition or even agricultural indicators. Modern astronomy, however, has not been very widespread, with only a few African countries having sufficient facilities or academics to support a modern astronomical community. The International Year of Astronomy serves not only as an opportunity to boost these astronomical communities, but also to celebrate the rich history and culture that has existed for thousands of years. On this, the poorest continent, with so many millions living in rural areas, there is one glaring advantage over other continents - people's abundant access to a dark night sky. We would like to see 2009 as the year that everyone in Africa, no matter what their background or lifestyle, turn their heads to the skies in appreciation of the beauty of the Universe, in celebration of their cultural heritage, and in the hope that they are inspired to overcome harsh challenges that this small planet and its occupants may have placed on them. It is an opportunity not just to promote astronomy, but also to spark curiosity and spur on a culture of learning. The perspective will be given from South Africa, home to a number of major astronomical facilities, and a major player in the development of astronomy across Africa. IYA2009 progress to date and plans for the future will be discussed.

    Twenty four specimens of holothuroids recently received from the South African Environmental and Observation Network (SAEON), collected from off the south and west coasts of South Africa, are herein recorded and/or described. The specimens comprise eight nominal and one indeterminate species and represent both shallow-water and deep-sea forms, distributed from Plettenberg Bay to just north of Lambert's Bay in the Western Cape Province. There are no new species but two new records for the South African region and extensions of horizontal and bathymetric distributions of the other species. Additions to the South African fauna are Zygothuria lactea (Théel, 1886) and Synallactes cf. challengeri (Théel, 1886). The paper also contains the first definite record of Thyone venusta Selenka, 1868, originally described from the Red Sea. Distribution ranges of the following species have been altered Synallactes viridilimus Cherbonnier, 1952; S. mollis Cherbonnier, 1952 and Psuedostichopus langeae Thandar, 2009.

  13. Contribution of mantle convection to shifting South American coastlines during the Tertiary

    To what degree does mantle convection drive sea-level change and subsequently coastline change around South America in the Tertiary? The westward movement of the South American plate implies the overriding of the Phoenix and Farallon slabs. Temperature and density anomalies of subducted slabs are preserved in the mantle and can be inferred from seismic tomography images. The currently subducting Nazca Plate, is expected to generate a dynamic surface topography effect, leading to variable surface tilting and vertical motions over time. We use numerical models to discern the contribution to subsidence or uplift due to mantle convection and slab subduction. Geodynamic modelling software, CitcomS combined with the GPlates software facilitates the modelling of linked plate kinematic and mantle convection processes. The quality of model output for the surface dynamic topography can be assessed by comparison with observations. These include geological data constraining surface uplift or subsidence, mantle tomography models, as well as regional versus global estimates of sea-level and palaeoshoreline analysis. Initial results show an encouraging connection between palaeogeography reconstructed from geological data and modelled dynamic topography. Modelled vertical motions suggest changes of up to ±1500m amplitude, or ~±150m/10Ma. A South American digital elevation model that is corrected for time-dependent dynamic topography effects, and inundated using a eustatic sea level model, shows a substantially improved agreement with mapped paleo-coastlines from geological data compared with an uncorrected elevation model. This supports the notion that mantle convection effects through time have played a profound role in driving shifts in coastlines and river drainage in South America. The uplift of the Andes has previously been suggested as attributing to the reversal in flow of the Amazon river. However, our results suggest an alternative mechanism for major Miocene changes in

    Analyzing data from a survey of African American and White residents in South Carolina, this study attempts to understand how to better promote clinical trial participation specifically within the African American population. To explore why participation is lower in the African American population, the authors examined two sets of potential barriers: structural/procedural (limited accessibility, lack of awareness, doctors not discussing clinical trial options, lack of health insurance) and cognitive/psychological (lack of subjective and factual knowledge, misperceptions, distrust, fear, perceived risk). Findings revealed that African Americans were significantly less willing than Whites to participate in a clinical trial. African Americans also had lower subjective and factual knowledge about clinical trials and perceived greater risk involved in participating in a clinical trial. The authors found that lack of subjective knowledge and perceived risk were significant predictors of African Americans' willingness to participate in a clinical trial. Implications of the findings are discussed in detail. PMID:26042496

    The advertising of dental services in South Africa is controlled by rules and regulations of the South African Medical and Dental Council. According to these, advertising is not permissible with the exception of specified professional information which may be made known only by means of a nameplate and an entry in a telephone directory. Questionnaires were sent to a randomised sample of 2,100 persons in order to determine the attitude of South Africans towards advertising by private practitioners. According to information obtained from this study there is a strong indication that consumers of dental services prefer a freer form of advertising by dentists in the private practice. PMID:1820668

    Introduction: Taenia solium is a common two-host parasitic cestode, residing in both humans (definitive) and pigs (intermediate). Invasion of this parasitic cyst into central nervous system leads to a condition known as neurocysticercosis (NCC). The World Health Organization (WHO) considers NCC as one of the “most neglected” tropical zoonotic diseases. The disease is presented with pleomorphic clinical manifestations, of which epilepsy is the most common. Diagnosis of NCC is carried out by serological tests and imaging methods. Only a few studies from Andhra Pradesh, Kerala, Tamil Nadu, and Pondicherry are available regarding the seropositive levels of NCC in South India. Materials and Methods: A descriptive analysis was carried out on NCC suspected patients attending outpatient or inpatient department of different clinics majorly from neurology, medicine, pediatrics, ophthalmology, and skin at Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry, a tertiary care hospital in South India. A total of 391 patient samples (either serum or cerebrospinal fluid or urine) for 5 years from January 2011 to December 2015 were taken into the study. Serological investigations such as enzyme-linked immunosorbent assay and enzyme-linked immunoelectro transfer blot were performed for assessing the seropositivity levels of NCC. Results: The overall seropositive cases of NCC in the study population were found to be 32.5% of which positive male cases (59.1%) exceeding females (40.9%). The frequency of adult positive cases (77.2%) was more than that of pediatrics cases (22.8%) with an average of 30.9 years of age. Conclusions: NCC seropositive levels show an increasing trend with the study period. This necessitates a proper attention to the unnoticed spread of the parasitic disease, which affects the quality of life in the community. Quality screening and diagnostic strategy should be implied along with proper awareness for preventive measure practices

    Integration of coastal onlap stratigraphy, calcareous nannofossil, dinoflagellate, and megafossil biostratigraphy provide new data for interpretation of age and interregional correlation of Paleocene to Oligocene deposits of the western South Carolina Coastal Plain. Clastic and calcareous sediments examined in cores and outcrops in the vicinity of the Savannah River Plant record at least seven coastal onlap cycles. Basal Tertiary sediments of the Ellenton Formation represent cycles TA1.1 - 1.3 and contain dinoflagellates of Midwayan to Sabinian age. The overlying Williamsburg Formation probably represents deposits of cycle TA2.1. The superjacent siliciclastics of the Congaree Formation contain few fossils, but may preserve transgressive and highstand deposits of cycles TA2.4 - 3.3. The overlying unit is commonly calcareous, contains nannofossils indicative of zones NP16-17 (Upper Claibornian), and marks a significant change in depositional style subsequent to the 49.5 Ma eustatic fall. ''Marls'' of the overlying Griffins Landing Member of the Dry Branch Formation contain micro- and megafossils of Late Eocene (Jacksonian) age and represent transgressive deposits of cycle TA4.1. The discontinuous lateral distribution of these calcareous units and overlying clastics of the Dry Branch and Tobacco Road Formations results largely from erosion and deep incision during the mid-Oligocene eustatic fall (30 Ma). The ''Upland'' unit is interpreted as being deposited on this erosional surface.

    Dental tissues provide important insights into aspects of hominid palaeobiology that are otherwise difficult to obtain from studies of the bony skeleton. Tooth enamel is formed by ameloblasts, which demonstrate daily secretory rhythms developing tissue-specific structures known as cross striations, and longer period markings called striae of Retzius. These enamel features were studied in the molars of two well known South African hominid species, Australopithecus africanus and Paranthropus robustus. Using newly developed portable confocal microscopy, we have obtained cross striation periodicities (number of cross striations between adjacent striae) for the largest sample of hominid teeth reported to date. These data indicate a mean periodicity of seven days in these small-bodied hominids. Important differences were observed in the inferred mechanisms of enamel development between these taxa. Ameloblasts maintain high rates of differentiation throughout cervical enamel development in P. robustus but not in A. africanus. In our sample, there were fewer lateral striae of Retzius in P. robustus than in A. africanus. In a molar of P. robustus, lateral enamel formed in a much shorter time than cuspal enamel, and the opposite was observed in two molars of A. africanus. In spite of the greater occlusal area and enamel thickness of the molars of both fossil species compared with modern humans, the total crown formation time of these three fossil molars was shorter than the corresponding tooth type in modern humans. Our results provide support for previous conclusions that molar crown formation time was short in Plio-Pleistocene hominids, and strongly suggest the presence of different mechanisms of amelogenesis, and thus tooth development, in these taxa.

    Enamel is formed incrementally by the secretory activity of ameloblast cells. Variable stages of secretion result in the formation of structures known as cross striations along enamel prisms, for which experimental data demonstrate a correspondence with daily periods of secretion. Patterns of variation in this daily growth are important to understanding mechanisms of tooth formation and the development of enamel thickness. Transmitted light microscopy (TLM) of histological ground sections and scanning electron microscopy (SEM) of bulk specimens or their surface replicas are the usual methods for investigating cross striations. However, these methods pose some constraints on the study of these features in Plio-Pleistocene hominid enamel, the specimens of which may only rarely be sectioned for TLM or examined on only their most superficial surfaces for SEM. The recent development of portable confocal scanning optical microscopy (PCSOM) resolves some of the restrictions on fractured enamel surfaces, allowing the visualization of cross striations by direct examination. This technology has been applied here to the study of Australopithecus africanus and Paranthropus robustus hominid molars from the Plio-Pleistocene of South Africa. We hypothesize that these taxa have increased enamel appositional rates compared with modern humans, because despite having thicker enamelled molars (particularly P. robustus), the enamel crowns of these fossil taxa take an equivalent or reduced amount of time to form. Cross striations were measured in cuspal, lateral and cervical regions of the enamel crowns, and, within each region, the inner, middle and outer zones. Values obtained for A. africanus outer zones of the enamel crown are, in general, lower than those for P. robustus, indicating faster forming enamel in the latter, while both taxa show higher rates of enamel growth than modern humans and the African great apes. This demonstrates a relatively high degree of variability in the

  2. Divergent thermal specialisation of two South African entomopathogenic nematodes

    Thermal physiology of entomopathogenic nematodes (EPN) is a critical aspect of field performance and fitness. Thermal limits for survival and activity, and the ability of these limits to adjust (i.e., show phenotypic flexibility) depending on recent thermal history, are generally poorly established, especially for non-model nematode species. Here we report the acute thermal limits for survival, and the thermal acclimation-related plasticity thereof for two key endemic South African EPN species, Steinernema yirgalemense and Heterorhabditis zealandica. Results including LT50 indicate S. yirgalemense (LT50 = 40.8 ± 0.3 °C) has greater high temperature tolerance than H. zealandica (LT50 = 36.7 ± 0.2 °C), but S. yirgalemense (LT50 = −2.4 ± 0 °C) has poorer low temperature tolerance in comparison to H. zealandica (LT50 = −9.7 ± 0.3 °C), suggesting these two EPN species occupy divergent thermal niches to one another. Acclimation had both negative and positive effects on temperature stress survival of both species, although the overall variation meant that many of these effects were non-significant. There was no indication of a consistent loss of plasticity with improved basal thermal tolerance for either species at upper lethal temperatures. At lower temperatures measured for H. zealandica, the 5 °C acclimation lowered survival until below −12.5 °C, where after it increased survival. Such results indicate that the thermal niche breadth of EPN species can differ significantly depending on recent thermal conditions, and should be characterized across a broad range of species to understand the evolution of thermal limits to performance and survival in this group.

    Using discriminant function analysis, classification accuracies for ancestry and sex in white and black South Africans were compared using North American (FDB), African groups in Howells (HDB), and South African (SADB) databases in FORDISC 3.0. (FD3). Twenty-four standard linear measures were collected from a total of 86 black and 101 white crania obtained from the Pretoria Bone Collection. White and black South Africans classified 73% correctly in FDB, 55% correctly in HDB, and 71% correctly in SADB. The percentage of atypical cases was higher with FDB than SADB. In all three databases, misclassification occurred more with sex than ancestry revealing differences in sexual dimorphism between population groups. Broad ancestral differences may explain low misclassification rates for ancestry. FD3, with a modern South African reference sample, can assist South African anthropologists to standardize methodology and to justify procedures for estimating ancestry.

    In children, craniofacial changes due to facial growth complicate facial approximations and require specific knowledge of soft tissue thicknesses (STT). The lack of South African juvenile STT standards of particular age groups, sex and ancestry is problematic. According to forensic artists in the South African Police Service the use of African-American values to reconstruct faces of Black South African children yields poor results. In order to perform a facial approximation that presents a true reflection of the child in question, information regarding differences in facial soft tissue at different ages, sexes and ancestry groups is needed. The aims of this study were to provide data on STT of South African Black and Coloured children and to assess differences in STT with respect to age, sex and ancestry. STT was measured using cephalograms of South African children (n=388), aged 6-13 years. After digitizing the images, STT measurements were taken at ten mid-facial landmarks from each image using the iTEM measuring program. STT comparisons between groups per age, sex and ancestry were statistically analyzed. The results showed that STT differences at lower face landmarks are more pronounced in age groups per ancestry as opposed to differences per age and sex. Generally, an increase in STT was seen between 6-10 year old groups and 11-13 year old groups, regardless of ancestry and sex, at the midphiltrum, labiale inferius, pogonion, and beneath chin landmarks. This research created a reference dataset for STT of South African children of Black and Coloured ancestry per age and sex that will be useful for facial reconstruction/approximation of juvenile remains.

    Assessment of pain intensity and its effect on quality of life is important for proper management of pain, but no validated pain assessment tools that assess pain intensity and the interference pain has on daily life are available in indigenous South African languages. Therefore, the aim of this study was to validate translated versions of the Wisconsin Brief Pain Questionnaire (WBPQ) in South African HIV-positive patients. The WBPQ was translated into three indigenous South African languages, Setswana, isiZulu, and Xitsonga. We interviewed 452 ambulatory HIV-positive patients (327 urban and 125 rural patients) between the ages of 20 and 76 years old. Factor analysis to assess construct validity identified a two-factor structure (pain intensity and pain interference) for the isiZulu (n=132), Xitsonga (n=125), and Setswana (n=66) versions of the WBPQ, whereas a three-factor structure (pain intensity, mood interference, and activity interference) was identified for the English (completed by English second-language speakers, n=129) version of the WBPQ. Cronbach alphas, calculated to assess the reliability of the pain intensity and pain interference scales, were greater than 0.70 for all scales in all four versions of the WBPQ, showing internal consistency within the dimensions. These results provide evidence of validity for an easily administered questionnaire, which assesses pain intensity and pain interference, in three indigenous South African languages, and for English second-language speakers, in a population of South African HIV-positive patients.

    Due to both deliberate and accidental introductions, invasive African Clawed Frog (Xenopus laevis) populations have become established worldwide. In this study, we investigate the geographic origins of invasive X. laevis populations in France and Portugal using the phylogeographic structure of X. laevis in its native South African range. In total, 80 individuals from the whole area known to be invaded in France and Portugal were analysed for two mitochondrial and three nuclear genes, allowing a comparison with 185 specimens from the native range. Our results show that native phylogeographic lineages have contributed differently to invasive European X. laevis populations. In Portugal, genetic and historical data suggest a single colonization event involving a small number of individuals from the south-western Cape region in South Africa. In contrast, French invasive X. laevis encompass two distinct native phylogeographic lineages, i.e., one from the south-western Cape region and one from the northern regions of South Africa. The French X. laevis population is the first example of a X. laevis invasion involving multiple lineages. Moreover, the lack of population structure based on nuclear DNA suggests a potential role for admixture within the invasive French population. PMID:26855879

    Rapid urbanisation has led African women to have an obesity prevalence double than that of Caucasian women, and this also holds true for the stroke prevalence in Africans. The study aimed to compare various metabolic syndrome (MS) criteria of the International Diabetes Federation (IDF) of body mass index and age-matched African (n=102) and Caucasian women (n=115). More Caucasian (30.4%) than African women (24.8%) had MS. Only 48% of African women had waist circumferences (WC) higher than the IDF cutoff, compared to 62.6% of Caucasians. Caucasian women were significantly taller and heavier and had higher triglycerides, plasminogen activator inhibitor-1 activity, and cortisol. African women had significantly higher blood pressure, leptin, fibrinogen and C-reactive protein, and higher odds ratios for having the MS for HDL-cholesterol, blood pressure, and fasting glucose than Caucasians. It is concluded that the IDF WC criterion needs a downward adjustment for African women due to a smaller body size. Lean African women seem to be at higher risk for MS than Caucasians. South Africa needs to stem the increasing rates of type 2 diabetes by decreasing obesity and by education (unschooled African women showed a 4.8 times higher likelihood of having MS than schooled women).

    Since becoming a democracy, South African legislation has changed. The South African Constitution and legislation governing the structures and mandate of the different spheres of government aim towards municipalities needing to become more developmental in the way it serves the community with a specific focus on the poor and vulnerable. It sets ideals to overcome the inheritance of the past. However, how to do this is sometimes still unclear. This paper is a case study illustrating how Stellenbosch Municipality overcame obstacles of perceived legislative restrictions, silo operations and antiquated thinking, working towards social inclusion for all its citizens. In moving away from disability accessibility and embracing universal access as a way in which to deliver basic services, Stellenbosch discovered the beginning of the process of overcoming the negative legacy of the past. Understanding the Universal Design principles and approach illustrated how South African municipalities can promote the concept of our rainbow nation as envisioned in the Constitution.

    African women are often thought to be protected from developing eating disorder pathology because they experience less cultural pressure to be thin. Yet, to our knowledge, no previous study has quantified the African body ideals portrayed by the media. We determined the African and Caucasian body ideals portrayed by the media in the United States (US) and South Africa (RSA), by calculating the average body mass index of male and female fashion models in the respective countries. The African female body ideal was significantly heavier than the Caucasian body ideal in the US, but significantly thinner than the Caucasian body ideal in RSA. The African male body ideal was significantly thinner than the Caucasian body ideal in both countries. Findings indicate that the body ideals portrayed by the media parallel the previously reported eating disorder pathology for both sexes, and in both countries. PMID:21184978

    Background: Dental pulp calcifications are unique and represent the dental pulp regenerative process. Dental pulp calcifications are sometimes routine findings in oral radiographs and may later serve as an important diagnostic criterion for a hidden aspect of systemic illness. Objective: The purpose of this study was to assess the patterns and prevalence of idiopathic dental pulp calcifications in a tertiary care setting in South India. Materials and Methods: A total of 227 patients were included in the study fulfilling the inclusion criteria. Age range of the study population was from 15 to 70 years. Teeth were examined under digital panoramic radiograph. The presence or absence of pulp stones was recorded. The presence of pulp stone were categorized according to the types classified as Type I, Type IA, Type II, Type IIA, Type II B, and Type III. The frequency of occurrence of pulp stones with sex, tooth type, dental arches, and types were compared with the types of calcification. Results: Total no. of patients with pulpal calcification were 227 [females 133 (58.59%) and males 94 (41.40%)]. The most common type between both sexes was Type I (48%). Total no. of teeth with calcification was 697; maxilla (48%), mandible (52%). The prevalence of pulp stone was found to be higher in the molars in both the arches. Most no. of pulp stones are reported at the third and fourth decade of life. Conclusion: Idiopathic dental pulp calcifications are incidental radiographic findings of the pulp tissue and also may be an indicator of underlying disease. PMID:23349577

  13. Tectonic implications of paleomagnetic poles from Lower Tertiary Volcanic Rocks, south central Alaska

    We have determined the paleolatitude of lower Tertiary volcanic rocks in southern Alaska to measure possible poleward translation of the Wrangellia and the Peninsular terranes after 50 m.y. ago. Previous paleomagnetic studies have shown that in Triassic and Jurassic time these terranes were located near the equator and have moved at least 3000 km poleward relative to the North American craton. Our sample localities are in the northern Talkeetna Mountains in mildly deformed andesite and dacite flows (50.4, 51.3, 53.9, and 56.3 m.y. by K-Ar) that overlap Lower Cretaceous flysch, Lower Permian volcanic rocks of Wrangellia, and Upper Triassic pillow basalt of the Susitna terrane. Results from 26 cooling units (23 of reversed polarity and 3 of normal polarity) give a mean paleomagnetic pole at 69.5°N, 179.6°E, α95 = 12.2°. Stratigraphic sections from opposite limbs of a syncline yield directional paths that pass the fold test, satisfying a necessary condition for primary origin of the magnetization. The corresponding mean paleolatitude (76°N) of the northern Talkeetna Mountains is 8°±10° higher than the latitude predicted from the Eocene reference pole for North America. Therefore, northward drift of the Talkeetna superterrane, which is the amalgamation of the Wrangellia and Peninsular terranes during and after Middle Jurassic time, was probably complete by 50 m.y. ago. Our results are consistent with paleomagnetic poles from uppermost Cretaceous and Paleocene volcanic sequences in Denali National Park, the Lake Clark region, northern Bristol Bay region, and near McGrath. These poles generally lie south of the cratonic poles, suggesting that the region between the Kaltag, Bruin Bay, and Castle Mountain faults has rotated counterclockwise relative to North America since the early Eocene.

    Reliable and valid population specific standards are necessary to accurately develop a biological profile, which includes an estimation of peer-reported social identification (Hefner, 2009). During the last 300 years, colonialism, slavery and apartheid created geographic, physical and social divisions of population groups in South Africa. The purpose of this study was to evaluate variation in nasal bone and aperture shape in a modern population of black, white, and coloured South Africans using standard craniometric variables and geometric morphometrics, namely general Procrustes and elliptical Fourier analyses. Fourteen standard landmarks were digitally recorded or computationally derived from 310 crania using a 3D coordinate digitizer for discriminant function, principal components and generalized Procrustes analyses. For elliptical Fourier analysis, outlines of the nasal aperture were generated from standardized photographs. All classification accuracies were better than chance; the lowest accuracies were for coloured and the highest accuracies were for white South Africans. Most difficulties arose in distinguishing coloured and black South African groups from each other. Generally, misclassifications were noted between the sexes within each group rather than among groups, which suggests that sex has less influence on nasal bone and aperture shape than ancestry. Quantifiable variation in shape of the nasal aperture region between white and non-white South African groups was observed.

    Martinez, Peter

    In the 1990s a team of scientists and engineers at Stellenbosch University built the first South African satellite to fly in space, the 64-kg Sunsat. This university-based satellite programme took advantage of the skills and facilities developed in the previous South African space programme of the 1980s and early 1990s, which had developed a much larger satellite (Greensat), but was cancelled in the mid-1990s prior to launch. Sunsat incorporated a number of novel capabilities for a microsatellite platform, and interest was shown in these technologies by other groups developing similar satellites. As the University was not the ideal environment to develop the commercial potential of these microsatellite technologies, a company called Sunspace was later established, thus creating industrial capacity in South Africa in a niche area of space technology. This new industrial capability, together with the infrastructure from the previous space programme, have created a foundation upon which to build the new South African space programme. This paper discusses the historical, current and possible future roles of small satellites in the development of the South African space programme.

    The increasing worldwide prevalence of type 2 diabetes mellitus (T2D) is a serious global health concern. Although T2D has a strong genetic etiology, limited knowledge exists about the common variants associated with it in the black South African population. This study set out to evaluate the association of previously reported common variants in other world populations with T2D susceptibility in a black South African population of Setswana descent. A case-control study design of 178 cases and 178 controls nested in the Prospective Urban Rural Epidemiology (PURE) study was conducted wherein we genotyped for 77 single nucleotide polymorphisms (SNPs). PLINK software was used to evaluate the standard genetic models of disease penetrance for the association of the common variants with impaired glucose tolerance (IGT) while adjusting for age, sex, and body mass index. Only rs1436955 significantly associated with an increase in T2D risk; three other variants, rs831571, rs8050136, and rs7542900, significantly associated with decreased risk of T2D. However, none of the four SNPs had significant associations after correcting for multiple testing (p<0.05). Although further studies are required to confirm these observations, the common variants associated with T2D risk among the Black South Africans of Setswana descent might likely be different than those in the Asian and European populations. This study supports the broader thesis that the genetic background of Africans is diverse and cannot be directly extrapolated using genetic variants from other ethnicities. Therefore there is a need to identify the population-specific variants linked with T2D in Africa. PMID:26382014

    Watkins, David A; Mayosi, Bongani M

    2009-01-01

    Summary Background Dilated cardiomyopathy (DCM) is a heart muscle disease that is endemic in Africa. Over the past 50 years, South African investigators have made significant contributions to scientific elucidation of the condition. The objective of this review was to summarise their research on the subject of DCM. Methods and results We searched PubMed for articles originating from South Africa and focusing on DCM or the related condition, peripartum cardiomyopathy (PCM). Reference lists and prominent South African researchers on DCM were also consulted. The prevalence of DCM is comparable in magnitude to that of other endemic heart conditions such as hypertension and rheumatic heart disease, although by comparison, DCM may cause disproportionate morbidity from heart failure. In the African context, malnutrition, excessive alcohol intake, prior myocarditis and genetic make-up have been proposed as aetiologies, and some or all of these factors may play an interrelated role in individual disease expression. The pathogenesis of DCM is partially due to the mechanical effects of fibrosis, and the immune response to myocardial damage likely affects disease progression. Small trials of pentoxifylline plus conventional therapy have demonstrated a trend towards reduced mortality from heart failure. Conclusions Despite half a century of noteworthy research, the pathogenic mechanisms of DCM are still incompletely understood. South Africans have, however, played and should continue to play a critical role in advancing research on DCM. PMID:19287809

  9. Trauma and posttraumatic stress disorder in South Africa: analysis from the South African Stress and Health Study

    PubMed Central

    2013-01-01

    Background South Africa’s unique history, characterised by apartheid, a form of constitutional racial segregation and exploitation, and a long period of political violence and state-sponsored oppression ending only in 1994, suggests a high level of trauma exposure in the general population. The aim of this study was to document the epidemiology of trauma and posttraumatic stress disorder (PTSD) in the South African general population. Methods The South African Stress and Health Study is a nationally representative survey of South African adults using the WHO’s Composite International Diagnostic Interview (CIDI) to assess exposure to trauma and presence of DSM-IV mental disorders. Results The most common traumatic events were the unexpected death of a loved one and witnessing trauma occurring to others. Lifetime and 12-month prevalence rates of PTSD were 2.3% and 0.7% respectively, while the conditional prevalence of PTSD after trauma exposure was 3.5%. PTSD conditional risk after trauma exposure and probability of chronicity after PTSD onset were both highest for witnessing trauma. Socio-demographic factors such as sex, age and education were largely unrelated to PTSD risk. Conclusions The occurrence of trauma and PTSD in South Africa is not distributed according to the socio-demographic factors or trauma types observed in other countries. The dominant role of witnessing in contributing to PTSD may reflect the public settings of trauma exposure in South Africa and highlight the importance of political and social context in shaping the epidemiology of PTSD.

    2008-08-01

    Hypertension is highly prevalent in South Africa, resulting in high stroke mortality rates. Since obesity is very common among South African women, it is likely that obesity contributes to the hypertension prevalence. The aims were to determine whether black African women have higher blood pressures (BPs) than Caucasian women, and whether obesity is related to their cardiovascular risk. African (N=102) and Caucasian (N=115) women, matched for age and body mass index, were included. Correlations between obesity (total body fat, abdominal obesity and peripheral fat) and cardiovascular risk markers (haemodynamic parameters, lipids, inflammatory markers, prothrombotic factors, adipokines, HOMA-IR (homoeostasis model assessment insulin resistance)) were compared between the ethnic groups (adjusted for age, smoking, alcohol and physical activity). Comparisons between low- and high-BP groups were also made for each ethnic group. Results showed that African women had higher BP (P<0.01) with increased peripheral vascular resistance. Surprisingly, African women showed significantly weaker correlations between obesity measures and cardiovascular risk markers when compared to Caucasian women (specifically systolic BP, arterial resistance, cardiac output, fibrinogen, plasminogen activator inhibitor-1, leptin and resistin). Interestingly, the latter risk markers were also not significantly different between low- and high-BP African groups. African women, however, presented significant correlations of obesity with triglycerides, C-reactive protein and HOMA that were comparable to the Caucasian women. Although urban African women have higher BP than Caucasians, their obesity levels are weakly related to traditional cardiovascular risk factors compared to Caucasian women. The results, however, suggest a link with the development of insulin resistance. PMID:18432254

    2010-01-01

    Diabetes is one of the most common metabolic disorders worldwide. It is a major health problem with its frequency increasing every day in most countries. The disease is generally believed to be incurable; and the few orthodox drugs available to manage the disease are not readily affordable to the poor. Based on the historical success of natural products as antidiabetic agents and the ever increasing need for new antidiabetics, a number of South African medicinal plants have been evaluated for their antidiabetic properties. In this article, we review the major studies conducted based on ethnobotanical surveys carried out between 2005 and 2008 in South Africa on plants that are traditionally used for the treatment of diabetes. Overall, the results of the studies conducted confirmed the potential of South African medicinal plants in antidiabetic drug discovery and identified a number of promising taxa for further in vivo investigation as plant-based antidiabetic agents.

  13. Depositional features and source and reservoir rocks of Tertiary age in northern part of South China Sea

    SciTech Connect

    1986-07-01

    The northern part of the South China Sea covers an area of about 400,000 km/sup 2/. Tertiary deposits more than 10,000 m in thickness are widely distributed there. The area has sedimentary rocks more than 1000 m thick covers more than 300,000 km/sup 2/. Five sedimentary basins have been established in this area: Beibu Bay, Yinggehai, Southeastern Qiong, Pearl River Mouth, and Southwestern Taiwann basins. The primary source and reservoir rocks for oil and gas prospects are of Tertiary age. Tertiary rocks underwent three stages of development, each forming a specific sedimentation system: (1) a system of fluviolacustrine deposits in rift depressions from the Paleocene to early Oligocene; (2) a system of semiclosed-sea deposits from the late Oligocene to early Miocene; and (3) a system of deltaic open-sea deposits from the middle Miocene to Pliocene. These three sedimentation systems resulted in three suites of source rocks, three suites of reservoir rocks, and three groups of independent oil pools, complete with source, reservoir, and cap rocks. The three suites of source rocks are as follows: (1) the Eocene Liushagang Formation in the Beibu Bay basin, which is believed to be the best source rock discovered in the area; (2) the Oligocene Zhuhai Formation in the Pearl River Mouth basin; and (3) the lower Miocene series in the Pearl River Mouth basin. The Eocene formation is probably the principal source rock of regional scale in the northern part of the South China Sea. The three suites of reservoir rocks are as follows: (1) the fluviolacustrine sandstone bodies in the Liushagang Formation; (2) the fluviolacustrine sand bodies and shallow-sea sandstone bodies in the Zhuhai Formation and Lingshu Formation; (3) the deltaic, littoral, and shallow-sea sand bodies and bioherms of Neogene age, with the middle Miocene sandstone reservoirs having the best physical properties.

    Cancer is projected to become a leading cause of morbidity and mortality in low-income and middle-income countries in the future. However, cancer incidence in South Africa is largely under-reported because of a lack of nationwide cancer surveillance networks. We describe present cancer surveillance activities in South Africa, and use the International Agency for Research on Cancer framework to propose the development of four population-based cancer registries in South Africa. These registries will represent the ethnic and geographical diversity of the country. We also provide an update on a cancer surveillance pilot programme in the Ekurhuleni Metropolitan District, and the successes and challenges in the implementation of the IARC framework in a local context. We examine the development of a comprehensive cancer surveillance system in a middle-income country, which might serve to assist other countries in establishing population-based cancer registries in a resource-constrained environment.

    1982-01-01

    A computer model using finite-difference techniques was used successfully to simulate the predevelopment flow regime within the multilayered Tertiary limestone aquifer system in Southeastern Georgia, Northeastern Florida, and Southern South Carolina as part of the U.S. Geological Survey 's Tertiary Limestone Regional Aquifer System analysis. The aquifer, of early Eocene to Miocene age, ranges from thin interbedded clastics and marl in the updip area to massive limestone and dolomite 1,500 feet thick in the downdip area. The aquifer is confined above by Miocene clay beds, and terminates at depth in low-permeability rocks or the saltwater interface. Model-simulated transmissivity of the upper permeable zone ranged from about 1 x 10 super 3 foot squared per day in the updip area and within parts of the Gulf Trough (a series of alinement basins filled by fine clastic in material) to about 1 x 10 super 6 foot squared per day in South Georgia, and area having large secondarily developed solution channels. The model results indicate that only about 540 cubic feet per second of water flowed through the predeveloped system, from the updip highland area of high altitude and in the areas north of Valdosta and southwest of Jacksonville, to discharge along streams in the updip area and diffuse upward leakage in the downdip area near the coast and offshore.

    Substance use is a common problem among South African youth. We conducted this study to determine whether religious beliefs influenced substance use among South African youth. We conducted a cross sectional study of 704 students from five high schools in South Africa. We used a questionnaire to assess self reported substance use and religious beliefs among the study subjects. We used binary logistic regression analysis to evaluate the relationship between the subjects' religious beliefs and substance use. Thirty-six point six percent of students reported being very religious. More female students reported being very religious than male students (p = 0.039). Fifty-four percent of students had ever consumed alcohol. Comparing alcohol and drug use between religious and non-religious students, it was found that alcohol and drug use were more common among non-religious students (28.3%, 30.4%) than very religious students (8.4%, 11.5%) (p < 0.05). Those who considered themselves religious had lower odds of substance use. Religious beliefs had an influence on substance use among South African youth in our study.

    2015-08-01

    South Africa has experienced a recent increase in thefts of heritage objects from museums and galleries around the country. While the exact number of incidences is not known, the increase in thefts is nonetheless apparent, and has revealed the weaknesses of the systems currently in place to respond to these crimes. The South African Heritage Resources Information System (SAHRIS) is an integrated, online heritage resources management tool developed by the South African Heritage Resources Agency (SAHRA) in 2011 in terms of Section 39 of the National Heritage Resources Act (NHRA), No. 25 of 1999. The system's combined heritage resources and site and object management functionality has been expanded to provide an integrated, responsive tool for reporting heritage crimes and tracking the progress of the resultant cases. This paper reviews existing legislative frameworks and crime reporting and monitoring systems relevant to fighting heritage crime, and identifies current gaps in those responses. SAHRIS is presented as an innovative tool to combat heritage crime effectively in the South African context by offering a centralised, consolidated platform that provides the various stakeholders involved in reporting heritage crimes and locating and retrieving stolen objects with a means to coordinate their responses to such instances.

    2015-09-01

    We investigated familial and environmental risk factors in a cohort of South African children diagnosed with attention-deficit hyperactivity disorder (ADHD). A prospective, hospital-based case control study was conducted comprising 50 children diagnosed with ADHD and 50 matched non-ADHD controls. The adjusted effect of familial-environmental risk factors on ADHD was determined by systematic assessment. Birth complications, parental psychiatric disorder, maternal ADHD, early childhood trauma, and nonmaternal child care were significant risk factors for ADHD. Prolonged breastfeeding was found to be protective. In a multivariable logistic regression model, 5 criteria (birth complications, breastfeeding <3 months, at least 1 parent with tertiary education, presence of parental psychiatric disorder, and nonmaternal primary caregiver) differentiated ADHD from non-ADHD controls with a sensitivity and specificity of 74% and 86%, respectively. We found a correlation between certain familial and environmental risk factors and ADHD. A 5-criterion multivariable logistic regression model may offer clinical guidance in ADHD diagnosis.

  2. Environmental stressors, low well-being, smoking, and alcohol use among South African adolescents.

    2011-05-01

    This is the first study to examine the pathways from environmental stressors to substance use among a sample of South African adolescents (N = 2195). The study objective was to assess how environmental stressors might affect cigarette smoking and alcohol use among South African adolescents, and to focus on one mechanism, low well-being, which might mediate this association. Participants consisted of 2195 Black, mixed ancestry ("Colored"), Indian, and White youth, aged 12-17 years old (mean age = 14.6; SD = 1.8), recruited via a multi-stage stratified sampling procedure in Durban, Cape Town, and Johannesburg, South Africa. Data were collected via individual in-person structured interviews, administered by trained interviewers in the participant's preferred language. Structural equation modeling was used to analyze the interrelationships of environmental stressors (violent victimisation, legal and illegal drug availability) and low well-being (depressive symptoms, low self-esteem, health problems) with respect to adolescent cigarette smoking and alcohol use. The results supported our hypotheses: Environmental stressors were related to low well-being which, in turn, was linked to both adolescent smoking and alcohol use. There were also direct pathways from environmental stressors to both adolescent smoking and alcohol use. Smoking and alcohol use were significantly correlated. The findings suggest that environmental stressors may be associated with diminished psychological and physical well-being, as well as smoking and alcohol use, among South African adolescents. Longitudinal research is warranted to further understand the interrelationship of environmental stressors, low well-being, and adolescent substance use, so that these issues may be addressed by South African programmes and policies.

  3. Junctophilin 3 (JPH3) expansion mutations causing Huntington disease like 2 (HDL2) are common in South African patients with African ancestry and a Huntington disease phenotype.

    Huntington disease (HD) is a progressive autosomal dominant neurodegenerative disorder, characterized by abnormal movements, cognitive decline, and psychiatric symptoms, caused by a CAG repeat expansion in the huntingtin (HTT) gene on chromosome 4p. A CAG/CTG repeat expansion in the junctophilin-3 (JPH3) gene on chromosome 16q24.2 causes a Huntington disease-like phenotype (HDL2). All patients to date with HDL2 have some African ancestry. The present study aimed to characterize the genetic basis of the Huntington disease phenotype in South Africans and to investigate the possible origin of the JPH3 mutation. In a sample of unrelated South African individuals referred for diagnostic HD testing, 62% (106/171) of white patients compared to only 36% (47/130) of black patients had an expansion in HTT. However, 15% (20/130) of black South African patients and no white patients (0/171) had an expansion in JPH3, confirming the diagnosis of Huntington disease like 2 (HDL2). Individuals with HDL2 share many clinical features with individuals with HD and are clinically indistinguishable in many cases, although the average age of onset and diagnosis in HDL2 is 5 years later than HD and individual clinical features may be more prominent. HDL2 mutations contribute significantly to the HD phenotype in South Africans with African ancestry. JPH3 haplotype studies in 31 families, mainly from South Africa and North America, provide evidence for a founder mutation and support a common African origin for all HDL2 patients. Molecular testing in individuals with an HD phenotype and African ancestry should include testing routinely for JPH3 mutations.

    2012-06-01

    Despite available guidelines on indications for fresh-frozen plasma (FFP) transfusion, inappropriate use is increasing worldwide. We evaluated FFP administration to patients admitted to the Steve Biko Academic Hospital over 4 months, including indications for use and completeness of requisition forms. Transfusions were considered inappropriate for 39.5% of units administered. Of request forms submitted, only 22% had sufficient information for the blood transfusion services of the indication for transfusion. Transfusion with FFP is a medical intervention that carries risks and should be undertaken with care. Although this study was conducted in one centre, it is evident that clinicians' lack of knowledge of the indications for administration of FFP is widespread. Intervention is necessary to improve patient outcomes and reduce expenditure.

  19. Why do some South African ethnic groups have very high HIV rates and others not?

    PubMed

    Kenyon, Chris; Zondo, Sizwe

    2011-04-01

    The differences in HIV prevalence between South Africa's racial/ethnic groups (19.9%, 3.2%, and 0.5% among 15-49-year-old blacks, coloureds and whites, respectively) are as big as those between the countries with the highest and lowest levels of HIV prevalence worldwide. These large racial/ethnic differences are largely determined by different sexual network structures. In networks among black South Africans, sexual partnerships are more likely to be arranged concurrently - a configuration that leads to exponential increases in the spread of HIV. An examination of the historical origins of polygamy (where it is normative for partnerships to be arranged concurrently) and monogamy (serial or lifetime) reveals that it is the practice of universal monogamy in stratified societies which is the outlier. The ideology and practice of universal monogamy originated in Europe as the result of several factors, most prominently conflicts between the Christian Church and the nobility. After its imposition in Europe, the European colonial project would see this ideology disseminated around the world. Under the influence of liberalism it would mutate into a secular and unacknowledged value-programme of monogamy as a universal norm. This value-programme and practice of monogamy (mostly serial) is still the norm for white South Africans; thus, this sexual behaviour 'spandrel' (by-product of other historical processes) is a large contributor to the lower levels of HIV prevalence among whites. In pre-colonial African societies, polygyny was normative, and the Christian value-programme of monogamy never achieved the hegemonic status it did in Europe and other areas of conquest. Married black African men who converted to Christianity were no less likely to have additional sexual partners, but only more likely to conceal them. The ongoing secrecy about having concurrent partners has contributed to the connectedness of sexual networks among black Africans at large and in this manner has

    2004-06-01

    Given the high rates of crime in South Africa's townships, nonpolitical violence out-side the home and its psychological impact on women were investigated within two samples, the primary a help-seeking sample and the secondary a community sample. In the help-seeking sample, two thirds of the women reported having experienced several traumatic events outside the home. Those women displayed a median of 9 PTSD (post-traumatic stress disorder) symptoms, with nearly half meeting all criteria for PTSD. In the community sample, 40 women of color were interviewed at a community festival for women, and again two thirds reported having experienced several traumatic events outside the home during the previous year. These women displayed a median of 8.8 PTSD symptoms, with none meeting all criteria for PTSD. South Africa's distinctive culture of violence is discussed as context for understanding issues of community violence and PTSD among women in its minority townships.

    The 7th African Rotavirus Symposium was held in Cape Town, South Africa, on the 8th November 2012 as a Satellite Symposium at the First International African Vaccinology Conference. Over 150 delegates participated in this symposium including scientists, clinicians, health officials, policymakers and vaccine manufacturers from across Africa. Key topics discussed included rotavirus surveillance, rotavirus vaccine introduction, post rotavirus vaccine impact analysis and intussusception data and surveillance in Africa. The symposium provided early rotavirus vaccine adopter countries in Africa (South Africa, Ghana and Botswana) an opportunity to share up-to-date information on vaccine introduction, and allowed colleagues to share experiences in establishing routine rotavirus surveillance (Tanzania, Niger and Rwanda). Overall, the symposium highlighted the high burden of rotavirus in Africa, and the need to continue to strengthen efforts in preventing rotavirus diarrhoea in Africa.

    2006-01-01

    Polymorphisms in the promoter region of the Cytochrome P4502E1 (CYP2E1) gene reportedly modify the metabolic activity of CYP2E1 enzyme, and have been associated with increased susceptibility to squamous cell carcinoma (SCC) of the oesophagus in high prevalence areas such as China. To assess the frequency of these polymorphisms in Black South Africans, a population with a high incidence of oesophageal SCC, this study examined genomic DNA from 331 subjects for restriction fragment length polymorphisms in the CYP2E1 (RsaI and PstI digestion). The frequency of the CYP2E1 c1/c1 and c1/c3 genotypes was 95% and 5% respectively. The frequency of the CYP2E1 allele distribution was found to be markedly different between Chinese and South African populations; hence it is important to place racial differences into consideration when proposing allelic variants as genetic markers for cancer.

    1991-04-01

    The aim of this study was to investigate the specific impact of a major migration-related stressor on the psychological functioning of Black South African migrants who had been coerced to migrate from their indigenous residence to an area designated by the South African government. Scales measuring stress, locus of control, and psychological status were administered to a sample of 50 involuntary farm migrants, 50 "voluntary" farm migrants, 50 "black spot" migrants, and 50 non-migrants. Subjects were male and female adults aged between 35 and 45 years. Results indicated that migrants perceived more stress and were more psychologically distressed than nonmigrants. This distress was particularly associated with the stressor lose home. Farm migrants perceived more external control than black spot and nonmigrant groups.

    Guse, Tharina; Hudson, Daphne

    2014-12-01

    This study aimed to explore the possible presence of psychological strengths and posttraumatic growth in the life stories of ex-offenders who desisted returning to crime. Recidivism rates in South African offenders released from prison remain as high as 97%. Little is known about positive psychological factors that may facilitate successful reentry of ex-offenders in the South African context. In an exploratory qualitative study, three adult male ex-offenders who had successfully reintegrated into society were interviewed, using a semi-structured interview schedule focusing on their life stories. Data was analyzed using thematic analysis. Several psychological strengths, including hope, gratitude, and spirituality, were evident in the responses of the participants. Furthermore, they seemed to experience a sense of posttraumatic growth. Identifying psychological strengths, including character strengths, may add to understanding and facilitating successful reintegration of ex-offenders. From these preliminary findings, implications for practice and research are proposed.

    The paper describes a clinical case of South African tick bite fever in a group of Russian tourists. The group of 5 people who had been ill with this disease after a tourist trip to the South African Republic (the Kruger National Park in the north-eastern province of Mpumalanga) were followed up. During their trip, all of them were bitten by different insects many times. The disease exhibited different clinical presentations; however, all the patients were noted to have a fever with slight intoxication and a maculopapular rash at different sites of the body; 3 had lymphadenopathy and one had a primary effect at the site of tick sticking. The diagnosis was verified by indirect immunofluorescence for the detection of high titers to Rickettsia conorii. The course of the disease was favorable in all the patients treated with antibiotics (doxycycline or ceftriaxone).

    2008-01-01

    The aim of this paper is to describe the optimisation of Waste Minimisation/Zero Waste strategies into an already established integrated waste management system and to present a Zero Waste model for post-consumer waste for urban communities in South Africa. The research was undertaken towards the fulfilment of the goals of the Polokwane Declaration on Waste Management [DEAT, 2001. Department of Environmental Affairs and Tourism, Government of South Africa. Polokwane Declaration. Drafted by Government, Civil Society and the Business Community. National Waste Summit, Polokwane, 26-28 September 2001], which has set as its target the reduction of waste generation and disposal by 50% and 25%, respectively, by 2012 and the development of a plan for Zero Waste by 2022. Two communities, adjacent to the Mariannhill Landfill site in Durban, were selected as a case study for a comparative analysis of formal and informal settlements. Since the waste generated from these two communities is disposed of at the Mariannhill landfill, the impact of Zero Waste on landfill volumes could be readily assessed. A Zero Waste scheme, based on costs and landfill airspace savings, was proposed for the area. The case study demonstrates that waste minimisation schemes can be introduced into urban areas, in emerging countries, with differing levels of service and that Zero Waste models are appropriate to urban areas in South Africa.

    PubMed Central

    Jackson, Pamela Braboy; Williams, David R.; Stein, Dan J.; Herman, Allen; Williams, Stacey L.; Redmond, Deidre L.

    2012-01-01

    We analyze data from the South African Stress and Health Study, a nationally representative in-person psychiatric epidemiologic survey of 4,351 adults conducted as part of the World Mental Health Survey Initiative between January 2002 and June 2004. All blacks (Africans, Coloreds, and Indians) initially report higher levels of non-specific distress and anger/hostility than whites. Access to socioeconomic resources helps explain differences in non-specific distress between Coloreds and whites and Indians and whites. However, only when social stressors are considered do we find few differences in psychological distress (i.e., non-specific distress and anger/hostility) between Africans and whites. In addition, self-esteem and mastery have independent effects on non-specific distress and anger/hostility, but differences between Coloreds and whites in feelings of anger/hostility are not completely explained by self-esteem and mastery. The findings contribute to the international body of work on social stress theory, challenge underlying assumptions of the minority status perspective, and raise a series of questions regarding mental health disparities among South Africans.

    2016-01-01

    The toad species Sclerophrys capensis Tschudi, 1838 was erected for a single specimen from South Africa which has never been properly studied and allocated to a known species. A morphometrical and morphological analysis of this specimen and its comparison with 75 toad specimens referred to five South African toad species allowed to allocate this specimen to the species currently known as Amietophrynus rangeri. In consequence, the nomen Sclerophrys must replace Amietophrynus as the valid nomen of the genus, and capensis as the valid nomen of the species. This work stresses the usefulness of natural history collections for solving taxonomic and nomenclatural problems. PMID:26788431

    2016-10-01

    The translation of well established psychometric tools from English into Xhosa may assist in improving access to psychological services for Xhosa speakers. The aim of this study was to translate the Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM), a measure of general distress and dysfunction developed in the UK, into Xhosa for use at South African university student counselling centres. The CORE-OM and embedded CORE-10 were translated into Xhosa using a five-stage translation design. This design included (a) forward-translation, (b) back-translation, (c) committee approach, (d) qualitative piloting, and (e) quantitative piloting on South African university students. Clinical and general samples were drawn from English-medium South African universities. Clinical samples were generated from university student counselling centres. General student samples were generated through random stratified cluster sampling of full-time university students. Qualitative feedback from the translation process and results from quantitative piloting of the 34-item CORE-OM English and Xhosa versions supported the reduction of the scale to 10 items. This reduced scale is referred to as the South African CORE-10 (SA CORE-10). A measurement and structural model of the SA CORE-10 English version was developed and cross-validated using an English-speaking university student sample. Equivalence of this model with the SA CORE-10 Xhosa version was investigated using a first-language Xhosa-speaking university sample. Partial measurement equivalence was achieved at the metric level. The resultant SA CORE-10 Xhosa and English versions provide core measures of distress and dysfunction. Additional, culture- and language-specific domains could be added to increase sensitivity and specificity.

    Cashew apple juice (CAJ) is one of the feedstocks used for biofuel production and ethanol yield depends on the physical and chemical properties of the extracted juice. As far as can be ascertained, information on physical and chemical properties of South African cashew apple juice is limited in open literature. Therefore, this study provides information on the physical and chemical properties of the South African cashew apple juice. Physicochemical characteristics of the juice, such as specific gravity, pH, sugars, condensed tannins, Vitamin C, minerals, and total protein, were measured from a mixed variety of cashew apples. Analytical results showed the CAJ possesses specific gravity and pH of 1.050 and 4.52, respectively. The highest sugars were glucose (40.56 gL(-1)) and fructose (57.06 gL(-1)). Other chemical compositions of the juice were condensed tannin (55.34 mgL(-1)), Vitamin C (112 mg/100 mL), and total protein (1.78 gL(-1)). The minerals content was as follows: zinc (1.39 ppm), copper (2.18 ppm), magnesium (4.32 ppm), iron (1.32 ppm), sodium (5.44 ppm), and manganese (1.24 ppm). With these findings, South African CAJ is a suitable biomass feedstock for ethanol production.

  14. Virulence of South African isolates of Haemophilus paragallinarum. Part 1: NAD-dependent field isolates.

    2002-06-01

    The virulence of four South African field isolates of NAD-dependent Haemophilus paragallinarum, representing the four serovars known to occur in that country, was investigated. During this study an alternative challenge model for infectious coryza was used, in which the infectivity as well the virulence of different isolates could be evaluated. The challenge model consisted of the direct challenge, via intrasinus injection of one chicken in a row of interconnected layer cages, containing 10 chickens, which are subsequently infected by natural routes. A scoring system of the clinical signs was established in which a score is given to the ability of the isolate to produce clinical signs in the challenge birds. The mean daily disease score for the flock can be calculated and plotted on a graph to give a graphic representation of the disease profile. A mean disease score, calculated over a 20-day examination period can be calculated. Isolates can then be compared to each other, either graphically or by a comparison of the mean disease scores. It has been demonstrated using this scoring system that the South African serogroup C isolates appear to be more virulent than the South African serogroup A or B isolates. It was further established that the serovar C-3 isolate appeared to be the most virulent.

    In this study, the sociocultural view of science as a language and some quantitative language features of the complementary theoretical framework of systemic functional linguistics are employed to analyse the utterances of three South African Physical Sciences teachers. Using a multi-case study methodology, this study provides a sophisticated description of the utterances of Pietermaritzburg Physical Sciences teachers in language contexts characterised by varying proportions of English Second Language (ESL) students in each class. The results reveal that, as expected, lexical cohesion as measured by the cohesive harmony index and proportion of repeated content words relative to total words, increased with an increasing proportion of ESL students. However, the use of nominalisation by the teachers and the lexical density of their utterances did not decrease with an increasing proportion of ESL students. Furthermore, the results reveal that each individual Physical Sciences teacher had a 'signature' talk, unrelated to the language context in which they taught. This study signals the urgent and critical need for South African science teacher training programmes to place a greater emphasis on the functional use of language for different language contexts in order to empower South African Physical Sciences teachers to adequately apprentice their students into the use of the register of scientific English.

    2013-01-01

    Background Crystalline silica and asbestos are common minerals that occur throughout South Africa, exposure to either causes respiratory disease. Most studies on silicosis in South Africa have been cross-sectional and long-term trends have not been reported. Although much research has been conducted on the health effects of silica dust and asbestos fibre in the gold-mining and asbestos-mining sectors, little is known about their health effects in other mining sectors. Objective The aims of this thesis were to describe silicosis trends in gold miners over three decades, and to explore the potential for diamond mine workers to develop asbestos-related diseases and platinum mine workers to develop silicosis. Methods Mine workers for the three sub-studies were identified from a mine worker autopsy database at the National Institute for Occupational Health. Results From 1975 to 2007, the proportions of white and black gold mine workers with silicosis increased from 18 to 22% and from 3 to 32% respectively. Cases of diamond and platinum mine workers with asbestos-related diseases and silicosis, respectively, were also identified. Conclusion The trends in silicosis in gold miners at autopsy clearly demonstrate the failure of the gold mines to adequately control dust and prevent occupational respiratory disease. The two case series of diamond and platinum mine workers contribute to the evidence for the risk of asbestos-related diseases in diamond mine workers and silicosis in platinum mine workers, respectively. The absence of reliable environmental dust measurements and incomplete work history records impedes occupational health research in South Africa because it is difficult to identify and/or validate sources of dust exposure that may be associated with occupational respiratory disease.

    Original data about venous channels in South African Plio-Pleistocene hominids are discussed. To assess possible changes in blood volume flow of fossil hominids, we test whether dimensions of three extracranial venous foramina were different between Australopithecus africanus and Australopithecus (Paranthropus) robustus. Moreover, providing further data about the small sample of South African Plio-Pleistocene hominids, we also attempt to re-analyse the incidence of divided hypoglossal canals and four emissary foramina in a very large sample of extant African apes representing all ages, species and subspecies, in A. africanus and in "robust australopithecines". Up to now, only very poor data on extracranial dimensions of venous foramina were available for fossil hominids. However, this topic provides interesting information about the modifications of volume flow during human evolution. Assuming that in fossil hominids, as in humans, dimensions of condylar and mastoid foramina, as well as those of jugular foramina, depended on volume flow through them, we conclude, first, that volume flow through internal jugular veins was comparable in South African australopithecines, extant chimpanzees and humans, and second, that, in comparison with the extant less-encephalized chimpanzees (presumably reflecting the ancestral condition), volume flow was higher through condylar veins in A. (P.) robustus. This increase was responsible for a significantly greater amount of blood drainage from the brain (and consequently an increased arterial blood supply). We support the view that encephalization was the prevailing functional explanation for volume flow increase through condylar veins in A. (P.) robustus, in comparison with its ancestor with its presumably more ape-like degree of encephalization. Considering the incidence of emissary canals and foramina, significant differences between A. africanus, "robust australopithecines" and all the extant African ape species, were tested

    Previous studies characterizing the Theileria parva p67 gene in East Africa revealed two alleles. Cattle-derived isolates associated with East Coast fever (ECF) have a 129bp deletion in the central region of the p67 gene (allele 1), compared to buffalo-derived isolates with no deletion (allele 2). In South Africa, Corridor disease outbreaks occur if there is contact between infected buffalo and susceptible cattle in the presence of vector ticks. Although ECF was introduced into South Africa in the early 20th century, it has been eradicated and it is thought that there has been no cattle to cattle transmission of T. parva since. The variable region of the p67 gene was amplified and the gene sequences analyzed to characterize South African T. parva parasites that occur in buffalo, in cattle from farms where Corridor disease outbreaks were diagnosed and in experimentally infected cattle. Four p67 alleles were identified, including alleles 1 and 2 previously detected in East African cattle and buffalo, respectively, as well as two novel alleles, one with a different 174bp deletion (allele 3), the other with a similar sequence to allele 3 but with no deletion (allele 4). Sequence variants of allele 1 were obtained from field samples originating from both cattle and buffalo. Allele 1 was also obtained from a bovine that tested T. parva positive from a farm near Ladysmith in the KwaZulu-Natal Province. East Coast fever was not diagnosed on this farm, but the p67 sequence was identical to that of T. parva Muguga, an isolate that causes ECF in Kenya. Variants of allele 2 were obtained from all T. parva samples from both buffalo and cattle, except Lad 10 and Zam 5. Phylogenetic analysis revealed that alleles 3 and 4 are monophyletic and diverged early from the other alleles. These novel alleles were not identified from South African field samples collected from cattle; however allele 3, with a p67 sequence identical to those obtained in South African field samples from

    Little is known about childhood lead absorption in South Africa. In this study a cross-sectional analytic survey was carried out to determine the blood lead levels and associated risk factors for inner-city, first-grade schoolchildren. Blood lead analyses, hematological and anthropometric measurements were conducted, and a pretested questionnaire was administered to parents to identify risk factors for lead exposure. In detailed environmental study, daily air and dust samples were collected over a period of 1 year from several sites in the study area, contemporaneously with the blood and questionnaire surveys. Spatial and temporal variations in atmospheric lead were determined. It was found that 13% of mixed race children, but no white children, had blood lead levels {ge} 25 {mu}g/dL, the US action level. Air lead levels averaged around 1 {mu}g/m{sup 3}, and dust lead levels ranged from 410 to 3620 ppm. Environmental lead levels were significantly elevated near heavy traffic, where Environmental Protection Agency standards were exceeded mainly during winter months. Baseline exposure was of significance in influencing blood lead levels of children attending schools in direct proximity to heavy traffic, where blood lead levels were elevated irrespective of other influencing factors. Primary and secondary preventive measures are urgently needed in South Africa to reduce environmental lead exposure.

    The aim of this paper is to describe the optimisation of Waste Minimisation/Zero Waste strategies into an already established integrated waste management system and to present a Zero Waste model for post-consumer waste for urban communities in South Africa. The research was undertaken towards the fulfilment of the goals of the Polokwane Declaration on Waste Management , which has set as its target the reduction of waste generation and disposal by 50% and 25%, respectively, by 2012 and the development of a plan for Zero Waste by 2022. Two communities, adjacent to the Mariannhill Landfill site in Durban, were selected as a case study for a comparative analysis of formal and informal settlements. Since the waste generated from these two communities is disposed of at the Mariannhill landfill, the impact of Zero Waste on landfill volumes could be readily assessed. A Zero Waste scheme, based on costs and landfill airspace savings, was proposed for the area. The case study demonstrates that waste minimisation schemes can be introduced into urban areas, in emerging countries, with differing levels of service and that Zero Waste models are appropriate to urban areas in South Africa.

    Objective Suicide and suicidal behaviours are significant public health problems and a leading cause of death worldwide and in South Africa. We examined the association between childhood adversities and suicidal behaviour over the life course. Methods A national probability sample of 4351 South African adult participants (aged 18 years and older) in the South African Stress and Health (SASH) study was interviewed as part of the World Mental Health Surveys initiative. Respondents provided sociodemographic and diagnostic information, as well as an account of suicide-related thoughts and behaviours. Suicidality or suicidal behaviour were defined as were defined as suicide attempts and suicidal ideation in the total sample, and suicide plans and attempts among ideators. Childhood adversities included physical abuse, sexual abuse, parental death, parental divorce, other parental loss, family violence, physical illness and financial adversity. The association between suicidality and childhood adversities was examined using discrete-time survival models. Results More than a third of the respondents with suicidal behaviour experienced at least one childhood adversity, with physical abuse, parental death and parental divorce being the most prevalent adversities. Physical abuse, sexual abuse and parental divorce were identified as significant risk markers for lifetime suicide attempts, while physical abuse and parental divorce were significantly correlated with suicidal ideation. Two or more childhood adversities were associated with a twofold higher risk of lifetime suicide attempts. Sexual abuse (OR 9.3), parental divorce (OR 3.1) and childhood physical abuse (OR 2.2) had the strongest associations with lifetime suicide attempts. The effect of childhood adversities on suicidal tendencies varied over the life course. For example, sexual abuse was significantly associated with suicide attempts during childhood and teen years, but not during young and later adulthood

    1991-05-01

    Structural studies conducted in the Lengwe and Mwabvi Karroo basins and in the basement in South Malawi, using regional maps and published data extended to cover Southeast Africa, serve to propose a series of geodynamic reconstructions which reveal the persistence of an extensional tectonic regime, the minimum stress σ3 of which has varied through time. The period of Karroo rifting and the tholeiitic and alkaline magmatism which terminated it, were controlled by NW-SE extension, which resulted in the creation of roughly NE-SW troughs articulated by the Tanganyika-Malawi and Zambesi pre-transform systems. These were NW-SE sinistral-slip systems with directions of movement dipping slightly to the Southeast, which enabled the Mwanza fault to play an important role in the evolution of the Karroo basins of the Shire Valley. The Cretaceous was a transition period between the Karroo rifting and the formation of the Recent East African Rift System. Extension was NE-SW, with some evidence for a local compressional episode in the Lengwe basin. Beginning in the Cenozoic, the extension once more became NW-SE and controlled the evolution in transtension of the Recent East African Rift System. This history highlights the major role of transverse faults systems dominated by strike-slip motion in the evolution and perpetuation of the continental rift systems. These faults are of a greater geological persistence than the normal faults bounding the grabens, especially when they are located on major basement anisotropies.

    Conceptualisations of mental illness are not universally applicable, as culture shapes the expression, perceptions and treatment preferences thereof. By focusing on the perceptions of Hindu psychologists regarding mental illness, this study aimed to provide a deeper understanding of the impact that religious beliefs have on such conceptualisations. Semi-structured interviews were conducted with six Hindu psychologists around the Johannesburg area, South Africa. Responses were analysed using thematic content analysis. From the findings, it was evident that religion plays a critical role in the understanding and treatment of mental illness. Hindu beliefs around psychological disturbances were salient. Additionally, it was found that a tension existed between psychologists' awareness of the influential function of religion, particularly amongst collectivistic communities such as the Hindu community, and their occupational understandings and practices, which are deeply rooted in Western thought. Furthermore, it was suggested that the fear of stigma prevented Hindu clients from reaping the benefits of seeking help from culturally competent psychologists. PMID:23054478

    In recent decades South Africa has witnessed a substantial growth in its urban population. This growth has been accompanied by the mushrooming of informal settlements (shantytowns) flanking more formal development. The lack of adequate urban drainage in many of these informal settlements has resulted in extremely polluted environments which add to the disease burden of the poor people who live there. In many instances, informal settlements in South Africa are established on marginal land that is inherently difficult to service using conventional gravity sewerage. International experience has shown that various alternative wastewater collection systems may present more appropriate ways of providing water-borne sewerage in areas that are difficult to service by conventional means. Alternative sewerage schemes have however had a poor record of success in South African informal settlements - primarily stemming from the implementing agencies' failure to adequately address various social and institutional factors. In this paper, a review of South African experiences with simplified sewerage, settled sewerage and vacuum sewerage in urban informal settlements is used to highlight the key constraints that currently impede the application of these technologies.

    This paper investigates how greenhouse gases are accounted and reported in the waste sector in South Africa. Developing countries (including South Africa) do not have binding emission reduction targets, but many of them publish different greenhouse gas emissions data which have been accounted and reported in different ways. Results show that for South Africa, inventories at national and municipal level are the most important tools in the process of accounting and reporting greenhouse gases from waste. For the development of these inventories international initiatives were important catalysts at national and municipal levels, and assisted in developing local expertise, resulting in increased output quality. However, discrepancies in the methodology used to account greenhouse gases from waste between inventories still remain a concern. This is a challenging issue for developing countries, especially African ones, since higher accuracy methods are more data intensive. Analysis of the South African inventories shows that results from the recent inventories can not be compared with older ones due to the use of different accounting methodologies. More recently the use of Clean Development Mechanism (CDM) procedures in Africa, geared towards direct measurements of greenhouse gases from landfill sites, has increased and resulted in an improvement of the quality of greenhouse gas inventories at municipal level.

    The eastern Argentina South Atlantic passive continental margin is distinguished by a very flat topography. Out of the so called Pampean flat two mountain ranges are arising. These mountain ranges, the Sierras Australes and the Sierras Septentrionales, are located in the State of Buenos Aires south of the capital Buenos Aires. In existing literature the Sierras Australes are correlated with the South African cape fold belt (Torsvik 2009; Lopez Gamundi & Rossello 1998). Existing thermochronological data shows different post-breakup cooling histories for both areas and different AFT-ages. Published thermochronological ages (e.g. Raab et al. 2002, 2005, Gallagher et al et al. 1998)from the south African escarpement vary around 150 and 100 Ma (Gallagher et al. 1998). Only some spots in the eastern part of South Africa towards the pacific margin show older ages of 250 Ma and older than 350 Ma (Gallagher et al. 1998). New thermochronological data (AHe, AFT and ZHe) from the Sierras Australes indicate a different cooling history by revealing a range of varying ages due to younger tectonic activity. By comparing the data sets from both areas it is getting clear that the post-rift evolution of both continents is differing very strong. Gallagher, K., Brown, R. and Johnson, C. 1998.

    Abstract A new genus is proposed for the strikingly patterned African vespertilionid “Glauconycteris” superba Hayman, 1939 on the basis of cranial and external morphological comparisons. A review of the attributes of a newly collected specimen from South Sudan (a new country record) and other museum specimens of “Glauconycteris” superba suggests that “Glauconycteris” superba is markedly distinct ecomorphologically from other species classified in Glauconycteris and is likely the sister taxon to Glauconycteris sensu stricto. The recent capture of this rarely collected but widespread bat highlights the need for continued research in tropical sub-Saharan Africa and in particular, for more work in western South Sudan, which has received very little scientific attention. New country records for Glauconycteris cf. poensis (South Sudan) and Glauconycteris curryae (Gabon) are also reported. PMID:23805046

    Background Adherence is crucial for public health program effectiveness, though the benefits of increasing adherence must ultimately be weighed against the associated costs. We sought to determine the relationship between investment in community health worker (CHW) home visits and increased attendance at cervical cancer screening appointments in Cape Town, South Africa. Methodology/Principal Findings We conducted an observational study of 5,258 CHW home visits made in 2003–4 as part of a community-based screening program. We estimated the functional relationship between spending on these visits and increased appointment attendance (adherence). Increased adherence was noted after each subsequent CHW visit. The costs of making the CHW visits was based on resource use including both personnel time and vehicle-related expenses valued in 2004 Rand. The CHW program cost R194,018, with 1,576 additional appointments attended. Adherence increased from 74% to 90%; 55% to 87%; 48% to 77%; and 56% to 80% for 6-, 12-, 24-, and 36-month appointments. Average per-woman costs increased by R14–R47. The majority of this increase occurred with the first 2 CHW visits (90%, 83%, 74%, and 77%; additional cost: R12–R26). Conclusions/Significance We found that study data can be used for program planning, identifying spending levels that achieve adherence targets given budgetary constraints. The results, derived from a single disease program, are retrospective, and should be prospectively replicated. PMID:19492097

    Africa is one of the less studied continents with respect to atmospheric aerosols. Savannahs are complex dynamic systems sensitive to climate and land-use changes, but the interaction with the atmosphere is not well understood. Atmospheric particles, aka aerosols, affect the climate on regional and global scale, and are an important factor in air quality. In this study measurements from a relatively clean savannah environment in South Africa were used to model new particle formation and growth. There are already some combined long-term measurements of trace gas concentrations together with aerosol and meteorological variables available, but to our knowledge this is the first time detailed simulations, that include all the main processes relevant to particle formation, were done. The results show that both investigated particle formation mechanisms overestimated the formation rates dependency on sulphuric acid. The approach including low volatile organic compounds to the particle formation process was more accurate in describing the nucleation events. To get reliable estimation of aerosol concentration in simulations for larger scales, nucleation mechanisms would need to include organic compounds, at least in southern Africa.

    Although listed in some publications as an activity associated with silica (quartz) exposure, agriculture is not widely recognized as an industry with a potential for silica associated diseases. Because so many people work in agriculture; and because silica exposure and silicosis are associated with serious diseases such as tuberculosis (TB), particular in those immunological compromised by the Human immunodeficiency virus (HIV), silica exposure in agriculture is potentially very important. But in South Africa (SA) very little is known about silica exposure in this industry. The objectives of this project are: (a) to measure inhalable and respirable dust and its quartz content on two typical sandy soil farms in the Free State province of SA for all major tasks done on the farms; and (b) to characterise the mineralogy soil type of these farms. Two typical farms in the sandy soil region of the Free State province were studied. The potential health effects faced by these farm workers from exposure to respirable crystalline silica are discussed.

    This article reviews the contributions of Cliff Malcolm while in South Africa during the period 1997-2005. It focuses on his contribution to the fields of science education, teacher education, learner-centered education, transformational outcomes-based education and HIV/AIDS education. In this paper we provide snapshots of his work as an academic, researcher, writer and humanist as he attempted to redefine scientific literacy to acknowledge the primacy of context and culture as mediating influences on meaningful learning, especially in rural communities. We make brief reference to his use of the Foucauldian conception of power to articulate the complementarity of power and energy as an expression of agency and action, the ultimate goal of a relevant science education. An important aspect of his empirical work with research units, universities and schools, was promoting an awareness of the foundational value of learner centred education which acknowledged the child as a `collective self' rather than an `autonomous self' as derived from the Western canon. Critical of imposing Western conceptions of science on Africa, he appropriates the indigenous concept of `ubuntu,' to demonstrate the danger of dichotomising and essentialising scientific truth while simultaneously marginalising indigenous knowledges.

  7. Towards setting environmental water temperature guidelines: a South African example.

    Water temperature is a primary factor affecting the number and kinds of species in a stream. A key step towards including water temperatures in environmental flow assessments is to develop metrics which describe natural variability in a river's thermal regime. This is best achieved using time series analyses, where metrics are defined based either on time series disaggregation, or shapes of regimes defined using agglomerative techniques. The aim of this paper was to refine approaches in setting environmental water temperature guidelines for inclusion in defining environmental flows assessments. Annual water temperature series from 82 sites sampled across 48 rivers (mainstems and tributaries) in ten catchments in the southern Cape region of South Africa were described using 39 metrics based on the magnitude, frequency, duration and timing of thermal events. Sites were classified into thermal groups using their similarity in multivariate temperature regime and variation amongst groups along important temperature gradients examined. Deviation from a natural range of variability using a thermal confidence envelope is a suitable approach for broad evaluation of thermal guidelines. The approach presented can be applied at multiple levels of complexity to assess which elements of a thermal time series fall outside of reference conditions. Further steps in this approach are to link thermal patterns to biotic metrics, and gain a clearer understanding of interactions between flows, temperatures and biota, particularly below impoundments. Research on improving approaches in defining thermal regions is recommended.

    Objective: The aim of the study was to assess the knowledge, attitude and practice of cigarette smoking behavior (CSB) in a sample of Indian matriculation students. Methodology: All (N=325) Indian matriculation students, at high schools, in Northern Kwa-Zulu Natal, South Africa, were included in the study. A questionnaire was administered to assess knowledge, attitudes and practice of CSB. Results and conclusion: The study showed a prevalence of 16.9%. Most smokers (98.2%) had commenced the practice after the age of 10 years. The most common reason given for CSB was experimentation (83.6%). Main influence was family members followed by teachers and advertisements. The association between smoking and lung cancer was well-known by smokers (90.7%). There was very little awareness of anti-smoking programmes or organizations. Alarmingly, there was little formal health education on the dangers of smoking in schools. The implications of these results are discussed and recommendations on decreasing CSB are made. PMID:23008583

    Clinical risk prediction is important in the prognostication of peri-operative cardiac complications and the management of high-risk cardiac patients for major non-cardiac surgery. However, the current pre-operative clinical risk indices have been derived in European and American patients and not validated in South African patients. The purpose of this study was to evaluate the utility of the clinical risk predictors identified in Lee's revised cardiac risk index and in the African arm of the INTERHEART study, in predicting cardiac mortality following vascular surgery in South African patients. A retrospective cohort study was conducted of all patients undergoing elective or urgent vascular surgery at Inkosi Albert Luthuli Central Hospital over a three-year period. All in-hospital deaths were identified and classified into cardiac or non-cardiac deaths by an investigator blinded to the patients' pre-operative clinical risk predicators. A second investigator blinded to the cause of death identified the following clinical risk predictors: history of ischaemic heart disease, congestive cardiac failure and cerebrovascular accident, presence of diabetes, hypertension and obesity (BMI > 30 kg.m(-2)), elevated serum creatinine (> 180 micromol.l(-1)), positive smoking history and ethnicity. The main finding was that a serum creatinine level of greater than 180 micromol.l(-1) and a positive smoking history were significantly associated with cardiac death (p = 0.012, p = 0.012, respectively). Multivariate analyses using a backward stepwise modeling technique found only a serum creatinine of > 180 micromol.l(-1) and a positive smoking history to be significantly associated with cardiac mortality (p = 0.038, 0.035, respectively) with an odds ratio and 95% confidence interval of 3.02 (1.06-8.59) and 3.40 (1.09-10.62), respectively. All other clinical predictors were not significantly different between the two groups. However, based on the sample size of this study, a type 2 or

    Despite the large differences in the epidemiology of hypertension across Europe, treatment strategies are similar for national populations of white European descent. However, hypertensive patients of African or South Asian ethnicity may require ethnic-specific approaches, as these population subgroups tend to have higher blood pressure at an earlier age that is more difficult to control, a higher occurrence of diabetes, and more target organ damage with earlier cardiovascular mortality. Therefore, we systematically reviewed the evidence on antihypertensive drug treatment in South Asian and African ethnicity patients. We used the Cochrane systematic review methodology to retrieve trials in electronic databases including CENTRAL, PubMed, and Embase from their inception through November 2015; and with handsearch. We retrieved 4596 reports that yielded 35 trials with 7 classes of antihypertensive drugs in 25,540 African ethnicity patients. Aside from the well-known blood pressure efficacy of calcium channel blockers and diuretics, with lesser effect of ACE inhibitors and beta-blockers, nebivolol was not more effective than placebo in reducing systolic blood pressure levels. Trials with morbidity and mortality outcomes indicated that lisinopril and losartan-based therapy were associated with a greater incidence of stroke and sudden death. Furthermore, 1581 reports yielded 16 randomized controlled trials with blood pressure outcomes in 1719 South Asian hypertensive patients. In contrast with the studies in African ethnicity patients, there were no significant differences in blood pressure lowering efficacy between drugs, and no trials available with mortality outcomes. In conclusion, in patients of African ethnicity, treatment initiated with ACE inhibitor or angiotensin II receptor blocker monotherapy was associated with adverse cardiovascular outcomes. We found no evidence of different efficacy of antihypertensive drugs in South Asians, but there is a need for trials

    South Africa has one of the highest rates of HIV/AIDS in the world. Much blame for this has been laid on the apathy of the South African government and the cultural traits of South Africans. AIDS prevention research calls for early childhood education to raise awareness of the causes, dangers, and prevention of HIV/AIDS. This study involved surveys among a select sample of South African adolescents to determine their sexual attitudes before and after a cognitive-behavioral intervention. Overall, the results did not make a significant difference in their attitudes, suggesting pre-adolescent sex education might prove to be a more useful tool in anti-HIV/AIDS education. Risky sexual behavior, under the influence of alcohol, also serves as a warning to educate young consumers of alcohol.

    Dissection of the pudendal nerve (PN) and its branches in 71 cadavers revealed anatomic variations not previously described. Knowledge of this variation is necessary to prevent nerve injury resulting in sexual of sensory dysfunction. Because descriptions vary, this study re-evaluated the anatomy of the PN as implicated in perineal procedures in South Africans. The course of the PN from the gluteal region into the perineum was dissected in an adult sample of both sexes and of African and European ancestry. Distances between PN and branches to applicable landmarks were measured. Basic descriptive statistics and comparisons were carried out between groups. In 5/13 African females, the inferior rectal nerve (IRN) entered the gluteal region separately and in 12/13 cases it passed medial to the ischial spine with the PN. The dorsal nerve of the clitoris or penis (DNC/DNP) was closer to the bony frame in those of European ancestry. The IRN branches were more superficial in females, but deeper in males of European ancestry. In African females, a PN block and Richter stitch should be placed more medial. Outside-in transobturator tape procedures might endanger the DNC/DNP in obese individuals. In females of European ancestry the IRN branches are compromised during ischioanal abscess drainage. In males of European ancestry, the dorsal penile nerve block might be less effective. Predictions should be verified clinically.

    BACKGROUND Prostate cancer incidence and mortality rates are significantly increased in African–American men, but limited studies have been performed within Sub–Saharan African populations. As mitochondria control energy metabolism and apoptosis we speculate that somatic mutations within mitochondrial genomes are candidate drivers of aggressive prostate carcinogenesis. METHODS We used matched blood and prostate tissue samples from 87 South African men (77 with African ancestry) to perform deep sequencing of complete mitochondrial genomes. Clinical presentation was biased toward aggressive disease (Gleason score >7, 64%), and compared with men without prostate cancer either with or without benign prostatic hyperplasia. RESULTS We identified 144 somatic mtDNA single nucleotide variants (SNVs), of which 80 were observed in 39 men presenting with aggressive disease. Both the number and frequency of somatic mtDNA SNVs were associated with higher pathological stage. CONCLUSIONS Besides doubling the total number of somatic PCa‐associated mitochondrial genome mutations identified to date, we associate mutational load with aggressive prostate cancer status in men of African ancestry.

    Africa is one of the less studied continents with respect to atmospheric aerosols. Savannahs are complex dynamic systems sensitive to climate and land-use changes, but the interaction of these systems with the atmosphere is not well understood. Atmospheric particles, called aerosols, affect the climate on regional and global scales, and are an important factor in air quality. In this study, measurements from a relatively clean savannah environment in South Africa were used to model new particle formation and growth. There already are some combined long-term measurements of trace gas concentrations together with aerosol and meteorological variables available, but to our knowledge this is the first detailed simulation that includes all the main processes relevant to particle formation. The results show that both of the particle formation mechanisms investigated overestimated the dependency of the formation rates on sulphuric acid. From the two particle formation mechanisms tested in this work, the approach that included low volatile organic compounds to the particle formation process was more accurate in describing the nucleation events than the approach that did not. To obtain a reliable estimate of aerosol concentration in simulations for larger scales, nucleation mechanisms would need to include organic compounds, at least in southern Africa. This work is the first step in developing a more comprehensive new particle formation model applicable to the unique environment in southern Africa. Such a model will assist in better understanding and predicting new particle formation – knowledge which could ultimately be used to mitigate impacts of climate change and air quality.

    Remote sensing offers a cost efficient means for identifying and monitoring wetlands over a large area and at different moments in time. In this study, we aim at providing ecologically relevant information on characteristics of temporary and permanent isolated open water wetlands, obtained by standard techniques and relatively cheap imagery. The number, surface area, nearest distance, and dynamics of isolated temporary and permanent wetlands were determined for the Western Cape, South Africa. Open water bodies (wetlands) were mapped from seven Landsat images (acquired during 1987 – 2002) using supervised maximum likelihood classification. The number of wetlands fluctuated over time. Most wetlands were detected in the winter of 2000 and 2002, probably related to road constructions. Imagery acquired in summer contained fewer wetlands than in winter. Most wetlands identified from Landsat images were smaller than one hectare. The average distance to the nearest wetland was larger in summer. In comparison to temporary wetlands, fewer, but larger permanent wetlands were detected. In addition, classification of non-vegetated wetlands on an Envisat ASAR radar image (acquired in June 2005) was evaluated. The number of detected small wetlands was lower for radar imagery than optical imagery (acquired in June 2002), probably because of deterioration of the spatial information content due the extensive pre-processing requirements of the radar image. Both optical and radar classifications allow to assess wetland characteristics that potentially influence plant and animal metacommunity structure. Envisat imagery, however, was less suitable than Landsat imagery for the extraction of detailed ecological information, as only large wetlands can be detected. This study has indicated that ecologically relevant data can be generated for the larger wetlands through relatively cheap imagery and standard techniques, despite the relatively low resolution of Landsat and Envisat imagery

    2005-05-01

    Although Sumner's ethnocentrism hypothesis, which expects stronger group identification to be associated with more negative outgroup attitudes, has been widely accepted, empirical findings have been inconsistent. This research investigates the relationship of four dimensions of ethnocultural group identification previously proposed by Phinney, that is, salience, evaluation, attachment, and involvement, with attitudes to ethnic outgroups in four South African ethnocultural groups (Africans, Afrikaans Whites, English Whites, Indians). The findings supported the factorial independence of the four identification dimensions and indicated that only one, ethnocultural evaluation (ingroup attitudes), was systematically related to outgroup attitudes, but the association could be positive, negative, or zero. Both functionalist and similarity-dissimilarity approaches to intergroup relations seemed to provide plausible explanations for the pattern of relationships obtained between ingroup and outgroup attitudes.

    Though African-American youth in the South are at high risk for HIV infection, abstinence until marriage education continues to be the only option in some public schools. Using community-based participatory research methods, we conducted 11 focus groups with African-American adults and youth in a rural community in North Carolina with high rates of HIV infection with marked racial disparities. Focus group discussions explored participant views on contributors to the elevated rates of HIV and resources available to reduce transmission. Participants consistently identified the public schools' sex education policies and practices as major barriers toward preventing HIV infection among youth in their community. Ideas for decreasing youth's risk of HIV included public schools providing access to health services and sex education. Policymakers, school administrators, and other stakeholders should consider the public school setting as a place to provide HIV prevention education for youth in rural areas.

    2012-03-01

    Climate changes in southern South America and the Antarctic Peninsula during the Tertiary show a strong correlation with ocean warming and cooling events, which are in turn related to tectonic processes. During periods of accelerated sea-floor spreading and mid-ocean ridge activity, sea-levels rose so that parts of the continents were flooded and forests were destroyed. However, this was balanced by the large-scale release of CO2 during volcanic outgassing and carbonate precipitation on the continental shelves, which caused rising air temperatures and the poleward expansion of (sub)tropical and temperate forests. Cooling episodes generally caused an increase in the north-south thermal gradient because of an equatorward shift in climate belts, so that the Westerly Winds intensified and brought higher rainfall to the lower latitudes. An increase in wind-blown dust caused temperatures to drop further by reflecting sunlight back into space. The rising Andes Range had a marked influence on climate patterns. Up to the middle Miocene it was still low enough to allow summer rainfall to reach central and north-central Chile, but after about 14 Ma it rose rapidly and effectively blocked the spill-over of moisture from the Atlantic Ocean and Amazon Basin. At this time, the cold Humboldt Current was also established, which together with the Andes helped to create the "Arid Diagonal" of southern South America stretching from the Atacama Desert to the dry steppes of Patagonia. This caused the withdrawal of subtropical forests to south-central Chile and the expansion of sclerophytic vegetation to central Chile. However, at the same time it intercepted more rain from the northeast, causing the effect of the South American monsoon to intensify in northwestern Argentina and southern Bolivia, where forest communities presently occur. In Patagonia, glaciation started as early as 10.5 Ma, but by 7 Ma had become a prominent feature of the landscape and continued apparently

    Background The high burden of witnessing traumatic events has been demonstrated in previous research in South Africa. However, previous work has focused on PTSD rather than a broader range of psychopathological outcomes. This study examined the association between witnessing trauma and multiple outcomes including mood, anxiety, and substance use disorders. Methods Regression models measured the odds of mood, anxiety, and substance use disorders among those who reported witnessing in the South African Stress and Health Study. Discrete-time survival analysis was used to examine whether witnessing was associated with earlier onset of mental disorders. Results Witnessing trauma was more commonly reported among males and those with low-average education. Posttraumatic stress disorder, mood, and anxiety disorders varied significantly with witnessing status, and witnessing was associated with exposure to a higher number of traumatic events compared to other types of traumatic events. Respondents reporting witnessing trauma had elevated odds of mood and anxiety disorders, but not substance use disorders. Conclusion Witnessing trauma is common in the South African population and results in increased risk of mood and anxiety disorders. Interventions aimed at reducing the burden of trauma and its outcomes must now increase their focus on bystanders and other observers, rather than just focusing on those directly affected.

    Although South Africa's total fertility rate is one of the lowest in sub-Saharan Africa, high rates of early childbearing remain a concern. Most teenage pregnancies occur among poor black and coloured South Africans. The majority of these pregnancies are said to be unwanted and unplanned and the teenager's relationships, unstable. Becoming a mother during one's teenage years is perceived to be socially, economically and physically deleterious for the teenager and her baby. This paper presents ethnographic data collected over a five-year period in the South African township of Nyanga East in the Western Cape. It draws attention to the circumstances that surround teenage pregnancy and discusses reactions to teenage pregnancies in this community. Findings highlight that despite the negative perception of teenage pregnancy within the township, particular social and cultural circumstances provided fertile ground for its occurrence. Furthermore, the paper argues that in this particular community the management of a teenage pregnancy played a functional and critical role in maintaining and reproducing social norms and ideals regarding intergenerational relationships, which ultimately ensured that the rates of early childbearing remained high.

Findings highlight that despite the negative perception of teenage pregnancy within the township, particular social and cultural circumstances provided fertile ground for its occurrence. Furthermore, the paper argues that in this particular community the management of a teenage pregnancy played a functional and critical role in maintaining and reproducing social norms and ideals regarding intergenerational relationships, which ultimately ensured that the rates of early childbearing remained high.

    The fungus Fusarium globosum was first isolated from maize in South Africa and subsequently from wheat in Japan. Here, multiple analyses revealed that, despite morphological similarities, South African maize and Japanese wheat isolates of the fungus exhibit multiple differences. An amplified fragment length polymorphism-based similarity index for the two groups of isolates was only 45%. Most maize isolates produced relatively high levels of fumonisins, whereas wheat isolates produced little or no fumonisins. The fumonisin biosynthetic gene FUM1 was detected in maize isolates by Southern blot analysis but not in the wheat isolates. In addition, most of the maize isolates produced sclerotia, and all of them produced large orange to dark purple sporodochia in carrot agar culture, whereas wheat isolates did not produce either structure. In contrast, individual isolates from both maize and wheat carried markers for both mating type idiomorphs, which indicates that the fungus may be homothallic. However, a sexual stage of F. globosum was not formed under standard self-fertilization conditions developed for other homothallic species of Fusarium. The inability to produce the sexual stage is consistent with the high similarity of 87-100% and G (ST) index of 1.72 for the maize isolates, which suggests that these isolates are undergoing asexual but not sexual reproduction. Together, the results suggest that the South African maize and Japanese wheat isolates of F. globosum are distinct populations and could be different species.

    Genetic susceptibility to tuberculosis (TB) has been well established and this, taken together with variation in susceptibility observed between different geographic and ethnic populations, implies that susceptibility to TB may in part be affected by ethnicity. In a previous genome-wide TB case-control study (642 cases and 91 controls) of the admixed South African Coloured (SAC) population, we found a positive correlation between African San ancestry and TB susceptibility, and negative correlations with European and Asian ancestries. Since genome-wide data was available for only a small number of controls in the previous study, we endeavored to validate this finding by genotyping a panel of ancestry informative markers (AIMs) in additional individuals, yielding a data set of 918 cases and 507 controls. Ancestry proportions were estimated using the AIMs for each of the source populations of the SAC (African San, African non-San, European, South Asian and East Asian). Using logistic regression models to test for association between TB and ancestry, we confirmed the substantial effect of ancestry on TB susceptibility. We also investigated the effect of adjusting for ancestry in candidate gene TB association studies of the SAC. We report a polymorphism that is no longer significantly associated with TB after adjustment for ancestry, a polymorphism that is significantly associated with TB only after adjustment for ancestry, and a polymorphism where the association significance remains unchanged. By comparing the allele frequencies of these polymorphisms in the source populations of the SAC, we demonstrate that association results are likely to be affected by adjustment for ancestry if allele frequencies differ markedly in the source populations of the SAC.

    This study assessed the genetic diversity in the growth hormone 1 gene (GH1) within and between South African goat breeds. Polymerase chain reaction-targeted gene amplification together with Illumina MiSeq next-generation sequencing (NGS) was used to generate the full length (2.54 kb) of the growth hormone 1 gene and screen for SNPs in the South African Boer (SAB) (n = 17), Tankwa (n = 15) and South African village (n = 35) goat populations. A range of 27-58 SNPs per population were observed. Mutations resulting in amino acid changes were observed at exons 2 and 5. Higher within-breed diversity of 97.37% was observed within the population category consisting of SA village ecotypes and the Tankwa goats. Highest pairwise FST values ranging from 0.148 to 0.356 were observed between the SAB and both the South African village and Tankwa feral goat populations. Phylogenetic analysis indicated nine genetic clusters, which reflected close relationships between the South African populations and the other international breeds with the exception of the Italian Sarda breeds. Results imply greater potential for within-population selection programs, particularly with SA village goats. PMID:26919178

    Malaria prevention in travelers depends upon dissemination of accurate information about malaria risk, prevention of mosquito bites, appropriate chemoprophylaxis use and knowledge of the symptoms of malaria. A study was undertaken of travelers to the Kruger National Park and private game parks in Mpumalanga Province, South Africa to investigate travelers knowledge, of malaria, chemoprophylaxis use, and experience of adverse events. In-flight self administered questionnaires were distributed and completed by travelers on flights returning to Johannesburg International Airport, from the malaria areas. The study was conducted during the highest malaria risk period during 1996. The Mpumalanga game parks are those most visited in South Africa and are found in the extreme northeast of the country, which adjoins Mozambique in the east and Zimbabwe in the north. This area is classified by the South African health authorities as being a high risk Malaria area.10 Chloroquine-resistant Plasmodium falciparum malaria has been described in this area.2,3 The Department of Health in South Africa recommends the use of mefloquine alone or the combination of chloroquine and proguanil, (doxycycline is prescribed for travelers in which the former antimalarials cannot be utilized), for visitors to this area during the high risk period for malaria, which extends from October to May.4 For the remainder of the year mosquito avoidance measures are recommended. Little is known about travelers' compliance with these recommendations and their knowledge of malaria. A study to explore these factors was undertaken as a joint initiative between the SAIMR travel clinic, Mpumalanga Department of Health, and the South African National Parks.

    Bullying victimisation has been prospectively linked with mental health problems among children and adolescents in longitudinal studies in the developed world. However, research from the developing world, where adolescents face multiple risks to social and emotional development, has been limited by cross-sectional designs. This is the first longitudinal study of the psychological impacts of bullying victimisation in South Africa. The primary aim was to examine prospective relationships between bullying victimisation and internalising and externalising symptoms in South African youth. Secondary aims were to examine gender and age-related differences in experiences of bullying victimisation. Children and adolescents (10-17 years, 57 % female, n = 3,515) from high HIV-prevalent (>30 %) communities in South Africa were interviewed and followed-up 1 year later (97 % retention). Census enumeration areas were randomly selected from urban and rural sites in two provinces and door-to-door sampling included all households with a resident child/adolescent. Exposure to multiple experiences of bullying victimisation at baseline predicted internalising symptoms and conduct problems 1 year later. Additionally, baseline mental health scores predicted later bullying victimisation, demonstrating bi-directionality of relationships between bullying victimisation and mental health outcomes in this sample. Expected gender differences in physical, verbal, and relational bullying victimisation were evident and predicted declines in bullying victimisation over time were observed. In the developed world, school-based anti-bullying programmes have been shown to be effective in reducing bullying and victimisation. Anti-bullying programmes should be implemented and rigorously evaluated in South Africa, as this may promote improved mental health among South African children and adolescents.

    Aims: To find out the prevalence and types of neurological abnormalities associated in auditory neuropathy spectrum disorder in a large tertiary referral center. Settings and Design: A prospective clinical study was conducted on all patients diagnosed with auditory neuropathy spectrum disorder in the ear, nose, and throat (ENT) and neurology departments during a 17-month period. Patients with neurological abnormalities on history and examination were further assessed by a neurologist to determine the type of disorder present. Results: The frequency of auditory neuropathy spectrum disorder was 1.12%. Sixty percent were found to have neurological involvement. This included cerebral palsy in children, peripheral neuropathy (PN), spinocerebellar ataxia, hereditary motor-sensory neuropathy, spastic paresis, and ponto-bulbar palsy. Neurological lesions did not present simultaneously with hearing loss in most patients. Sixty-six percent of patients with auditory neuropathy spectrum disorder were born of consanguineous marriages. Conclusions: There is a high prevalence of neurological lesions in auditory neuropathy spectrum disorder which has to be kept in mind while evaluating such patients. Follow-up and counselling regarding the appearance of neuropathies is therefore important in such patients. A hereditary etiology is indicated in a majority of cases of auditory neuropathy spectrum disorder. PMID:26019414

    A block of pitchstone in the northern Black Hills, South Dakota, is Paleocene in age, according to potassium-argon dating of biotite and fission-track dating of zircon in the sample. These data invalidate published suggestions that the age is much younger. The pitchstone is not extrusive in its present position but instead is in a volcanic pipe with other fragments that came downward from as much as 1100 meters above the modern surface.

    Objectives. To aid future policy and intervention initiatives, we studied the prevalence and correlates of overweight and obesity among participants in the South African National Youth Risk Behaviour Survey in 2002 and 2008. Methods. The survey collected data from nationally representative cross-sectional samples of students in grades 8 through 11 (n = 9491 in 2002 and 9442 in 2008) by questionnaire and measurement of height and weight. We stratified data on overweight and obesity rates by age, socioeconomic status, and race/ethnicity. Results. Among male adolescents, overweight rates increased from 6.3% in 2002 to 11.0% in 2008 (P < .01); among female adolescents, overweight rates increased from 24.3% in 2002 to 29.0% in 2008 (P < .01). Obesity rates more than doubled among male adolescents from 1.6% in 2002 to 3.3% in 2008 (P < .01) and rose from 5.0% to 7.5% among female adolescents (P < .01). We observed a dose–response relationship in overweight and obesity rates across socioeconomic categories. Rates of overweight and obesity were significantly higher among urban youths than among rural youths (P < .01). Conclusions. South Africa is experiencing a chronic disease risk transition. Further research is needed to better understand and effectively address this rapid change. PMID:21940919

    This study explored narratives of drinking as a coping strategy among female drinkers in a South African township. In 2010–11, we conducted qualitative in-depth interviews with 54 women recruited from 12 alcohol-serving venues. Most women drank heavily and linked their drinking to stressors. They were motivated to use drinking to manage their emotions, facilitate social engagement, and achieve a sense of empowerment, even while recognizing the limitations of this strategy. This study helps to contextualize heavy drinking behavior among women in this setting. Multifaceted interventions that help female drinkers to more effectively manage stressors may aid in reducing hazardous drinking. PMID:23905586

    Globally, chronic diseases place a tremendous burden on health care systems all over the world. The increased prevalence of chronic diseases is mainly influenced by industrialization and decreased levels of physical activity. A cross-sectional qualitative and quantitative pilot survey, using a self-administered questionnaire and focus group discussions, was conducted with 73 students to assess the need for and feasibility of a health promotion program for university students at a rural South African university. The results of this survey suggest that there is a need for a health promotion program aimed at young adults who attend university. PMID:25635164

    We report briefly on an application of random matrix theory to the analysis of SA financial market data (An Analysis of cross-correlations in South African financial market data, e- print cond-mat/0402389). Correlation matrices C are constructed from 10 years of daily data for stocks listed on the Johannesburg Stock Exchange from January 1993 to December 2002. Spectral properties of C are tested against random matrix predictions. We highlight some quantitative differences which arise when treating prices as existing only when measured, as opposed to interpolating missing or illiquid trading days with a zero-order hold.

    Ninety-five members of three South African Indian families were examined for neurofibromatosis (NF) and 45 were deemed to be affected in terms of accepted diagnostic criteria. Analysis of the pedigrees revealed autosomal dominant inheritance with full penetrance. The absence of macromelanosomes in skin biopsies of café-au-lait macules and the failure to detect Lisch nodules (hamartomas of the iris) in this population group raises further evidence that NF might be a heterogeneous condition. The potential importance of heterogeneity in molecular linkage studies is emphasised.

    1996-01-01

    Derived from a marxist/liberal humanist view of power, conventional critiques of the South African gold mining industry's medical apparatus see only its power to repress and negate the true bodily attributes and authentic person of the African mine worker. In so doing, they ignore the productive capacity of medical practice as a manifestation of what Foucault termed "disciplinary" power, by which the human body is manufactured and made manageable as an object of medical knowledge and industrial utilization. Accordingly, this paper offers just such a Foucaultian reading of South African mining medicine to demonstrate how it has operated to fabricate the bodies of African miners as visible objects possessed of distinct attributes that provoked particular strategies for their surveillance in health and disease.

    Background: Globally, methicillin resistant Staphylococcus aureus (MRSA) is one of the most common pathogens that causes hospital- and community-acquired infections. The use of molecular typing methods is essential for determining the origin of the isolates, their clonal relations, and also epidemiological investigations. Objective: The purpose of this study was to determine the prevalence of antibiotic-resistant MRSA investigate the accessory gene regulator (agr) and staphylococcal cassette chromosome mec (SCCmec) types and perform multilocus sequence typing (MLST). Furthermore, the minimum inhibitory concentration of MRSA isolates was determined for vancomycin and daptomycin. Materials and Methods: Two hundred and fifty-nine MRSA isolates were collected from Tertiary Care Hospitals in Coimbatore. Disk diffusion method was employed to assess the sensitivity of MRSA isolates to selected antibiotics and genetic analysis was performed using SCCmec, agr, and MLST typing by multiplex-polymerase chain reaction strategy. Minimal inhibitory concentration (MIC) was determined using Ezy MIC (vancomycin) and Biomerieux (daptomycin) E-test strip. Results: Of 259 MRSA isolates, 209 (80.7%) were confirmed as methicillin resistant. Antibiotic susceptibility pattern revealed that all the MRSA isolates were 100% sensitive to linezolid, rifampicin, teicoplanin, and vancomycin. MIC results showed that of 209 MRSA isolates, 10 were found to be vancomycin intermediate S. aureus and 100% of the MRSA isolates were daptomycin-susceptible. The agr group I and SCCmec Type III were the major type among MRSA isolates. In addition to these MLST typing revealed the prevalence of sequence type (ST) 239 (SLV of ST8) among the MRSA isolates. Conclusion: This study confirms that ST239 (Brazilian clone) of MRSA is predominant in this region which is responsible for the hospital-acquired MRSA infections. Thus, the study also suggests that vancomycin and daptomycin can still be used as an alternative

  18. A critical analysis of the South African Disaster Management Act and Policy Framework.

    The promulgation of the South African Disaster Management Act No. 57 of 2002 and the National Disaster Management Policy Framework of 2005 placed South Africa at the international forefront by integrating disaster risk reduction into all spheres of government through a decentralised approach. Yet, good policy and legislation do not necessarily translate into good practice. This paper provides a critical analysis of the Act and Policy Framework. Using qualitative research methods, it analyses the attitudes and perceptions of senior public officials on all levels of government, the private sector and academia. The study finds that one of the weakest aspects of the Act and Framework is the absence of clear guidance to local municipalities. The placement of the disaster risk management function on all tiers of government remains problematic, funding is inadequate and overall knowledge and capacities for disaster risk reduction are insufficient.

  19. Maternal incest as moral panic: envisioning futures without fathers in the South African lowveld.

    2010-01-01

    During 2008, rumours about revolting incestuous encounters between sons and their mothers circulated in the Bushbuckridge municipality of the South African lowveld. This article views these rumours as expressing moral panic, paying particular attention to the historical contexts of their emergence and circulation, and to their temporal orientation. I locate these rumours in the periphery of South Africa's de-industrialising economy, marked by increased unemployment and criminality among men and by a growing prominence of women-headed households. They express a regressive temporalisation and pessimistic vision, not of development, progress and civilisation, but rather of deterioration and de-civilisation. Through the alleged act of incest, sons who engage in crime usurp the authority of fathers who once produced value in strategic industries and mines. As such the rumours envision a dystopia marked by the 'death of the father' and chaotic disorder without morality and law.

    Piroplasms, including Babesia, Cytauxzoon and Theileria species, frequently infect domestic and wild mammals. At present, there is no information on the occurrence and molecular identity of these tick-borne blood parasites in the meerkat, one of South Africa's most endearing wildlife celebrities. Meerkats live in territorial groups, which may occur on ranchland in close proximity to humans, pets and livestock. Blood collected from 46 healthy meerkats living in the South-African Kalahari desert was screened by microscopy and molecular methods, using PCR and DNA sequencing of 18S rRNA and ITS1 genes. We found that meerkats were infected by 2 species: one species related to Babesia sp. and one species related to Cytauxzoon sp. Ninety one percent of the meerkats were infected by the Cytauxzoon and/or the Babesia species. Co-infection occurred in 46% of meerkats. The pathogenicity and vectors of these two piroplasm species remains to be determined.

    2014-11-01

    The implementation of Catchment Management Agencies (CMAs) was supposed to be the cornerstone of the rescaling process of the South African water reform policy. Yet, less than 10 years after the adoption of the National Water Act, the process was suspended for 4 years and by 2012 only two CMAs had been established. Combining approaches in geography and political science, this paper investigates the reasons for the delays in CMAs' implementation in South Africa. It shows that the construction of interbasin transfers (IBTs) since the 1950s by the apartheid regime and nowadays the power struggles between CMAs and the Department of Water Affairs (DWA) are two of the main obstacles to the creation of CMAs planned by the 1998 National Water Act (NWA). Finally, the paper advocates taking the "hydrosocial cycle" as an analytical framework for designing new institutional arrangements that will include both rectifying the legacy of the past (the specific role of DWA) and acknowledging legitimate local interests.

    Background Eliminating silicosis is a priority of the International Labour Organization and the World Health Organization. Prevalence is particularly high in developing countries. Objectives We describe trends in silicosis among South African gold miners who had had an autopsy between 1975 and 2007 and quantify the contributions of age at autopsy and employment duration to these trends. Methods South African miners and ex-miners are eligible for autopsy examination for occupational lung disease, regardless of the clinical cause of death, and the families of deceased mine workers may receive compensation from the government of South Africa. Miners who died from external causes and who had been employed in the gold mines for > 1 year were stratified by population group because of differences in exposure, patterns of employment, and autopsy referral patterns. We extracted data from PATHAUT (Pathology Automation System) and used Stata 10 to estimate trends in relative proportions of silicosis that were standardized for age and employment duration. Results The crude proportion of silicosis for white miners was six times that of black miners in 1975. By 2007, it was 1.5 times higher for black miners. The proportion of miners with silicosis increased from 0.03 to 0.32 for black miners and from 0.18 to 0.22 for white miners. The increase can be explained by increasing age and employment duration for white miners. For black miners, it can be only partly explained by these two factors. Conclusion As miners continue to age and work for longer periods, the burden of silicosis will continue to rise. South Africa is committed to global efforts to eliminate silicosis by 2030. The autopsy database allows for disease surveillance, which is necessary to monitor the success of this initiative. PMID:20194070

    Glyphosate-based herbicides are among the leading products used in South Africa to control weeds and invading alien plant species. Although these herbicides ultimately find their way into aquatic ecosystems, South Africa has no water quality guideline based on indigenous species to protect the country's aquatic biota against these biocides. In this study, South African water quality guidelines (SAWQGs) for Roundup(®) based on species sensitivity distribution (SSD) using indigenous aquatic biota were developed. Short-term and long-term toxicity tests were conducted with eight different aquatic species belonging to five different taxonomic groups. Static non-renewal experimental methods were employed for short-term lethal tests (≤4 days), and static renewal for long-term sublethal tests (≥4 days ≤21 days). LC50 values for animal exposure and EC50 values for algae were calculated using probit analysis and linear regression of transformed herbicide concentration as natural logarithm data against percentage growth inhibition, respectively. No effect concentration (NEC) was determined based on the dynamic energy budget model, using survival data. The LC50, EC50 and NEC values were used to develop species sensitivity distribution (SSD) concentrations for Roundup(®). Based on the SSD concentrations, the short-term and long-term SAWQGs for Roundup(®) were derived as 0.250 (0.106-0.589) mg/L, and 0.002 (0.000-0.021) mg/L, respectively. These WQGs may be useful in protecting South African aquatic life against transient or long-term exposure to glyphosate-based chemicals as part of integrated water resources management.

    1997-12-01

    This paper is about power, medicine and the identity of the African as a patient of western medicine. From a conventional perspective and as encoded in the current "quest for wholeness" that characterises South African biomedical discourse, the African patient--like any other patient--has always existed as an authentic and subjectified being, whose true attributes and experiences have been denied by the "mechanistic," "reductionistic" and "ethnocentric" practices of clinical medicine. Against this liberal humanist perspective on the body as ontologically independent of power, this paper offers a Foucaultian reading of the African patient as-like any other patient--contingent upon the force relations immanent within and relayed through the clinical practices of biomedicine. A quintessential form of disciplinary micro-power, these fabricate the most intimate recesses of the human body as manageable objects of medical knowledge and social consciousness to make possible the great control strategies of repression, segmentation and liberation that are the usual focus of conventional investigations into the place and function of medicine in society. Since the 1930s when the African body first emerged as a discrete object of a secular clinical knowledge, these have repeatedly transformed the attributes and identity of the African patient, and the paper traces this archaeology of South African clinical perception from then until the 1990s to show how its "quest for wholeness" is not an end point of "discovery" or "liberation," but merely another ephemeral crystallization of socio-medical knowledge in a constantly changing force field of disciplinary power.

    Despite South Africa's history of violent political conflict, and the link between stressful experiences and smoking in the literature, no public health study has examined South Africans' experiences of human rights violations and smoking. Using data from participants in the nationally representative cross-sectional South Africa Stress and Health study (SASH), this analysis examined the association between respondent smoking status and both human rights violations experienced by the respondent and violations experienced by the respondents' close friends and family members. SAS-Callable SUDAAN was used to construct separate log-binomial models by political affiliation during apartheid (government or liberation supporters). In comparison to those who reported no violations, in adjusted analyses, government supporters who reported violations of themselves but not others (RR = 1.76, 95% CI: 1.25-2.46) had a significantly higher smoking prevalence. In comparison to liberation supporters who reported no violations, those who reported violations of self only (RR = 1.56, 95%CI: 1.07-2.29), close others only (RR = 1.97, 95%CI: 1.12-3.47), or violations of self and close others due to close others' political beliefs and the respondent's political beliefs (RR = 2.86, 95%CI: 1.70-4.82) had a significantly higher prevalence of smoking. The results of this analysis suggest that a relationship may exist between human rights violations and smoking among South Africa adults. Future research should use longitudinal data to assess causality, test the generalizability of these findings, and consider how to apply these findings to smoking cessation interventions.

    This paper discusses the planning and development of a South African national health knowledge network. The methodology is in essence based on the principles of knowledge management and the drivers of a system of innovation. The knowledge network, SA HealthInfo, aims to provide a one-stop interactive forum/resource, for quality-controlled and evidence-based health research information, to a wide spectrum of users, at various levels of aggregation, with the necessary security arrangements and facilities for interaction among users to promote explicit (codified) and tacit knowledge flow. It will therefore stimulate the process of innovation within the South African health system.

    The abundance and distribution of parasitic helminths in populations of African buffaloes, Syncerus caffer, have not been well documented. A total of 28 buffaloes of different ages and sexeswere sampled in the Kruger National Park, South Africa, for nematodes of the small intestine. Three nematode species were identified, namely Cooperia fuelleborni, Cooperia hungi and Trichostrongylus deflexus, with C. hungi being a new country record for African buffalo in South Africa. The overall prevalence was 71%and the average number of worms was 2346 (range: 0-15 980). This is a small burden for such a large mammal. Sex, age and body condition of the buffaloes had no significant effect on worm occurrence.

    Stable isotope ratios ((13)C/(12)C and (15)N/(14)N) of South African Dorper lambs from farms with different vegetation types were measured by isotope ratio mass spectrometry (IRMS), to evaluate it as a tool for the authentication of origin and feeding regime. Homogenised and defatted meat of the Longissimus lumborum (LL) muscle of lambs from seven different farms was assessed. The δ(13)C values were affected by the origin of the meat, mainly reflecting the diet. The Rûens and Free State farms had the lowest (p ⩽ 0.05) δ(15)N values, followed by the Northern Cape farms, with Hantam Karoo/Calvinia having the highest δ(15)N values. Discriminant analysis showed δ(13)C and δ(15)N differences as promising results for the use of IRMS as a reliable analytical tool for lamb meat authentication. The results suggest that diet, linked to origin, is an important factor to consider regarding region of origin classification for South African lamb.

    The apartheid policies in South Africa had a marked influence on the accessibility and quality of school science experienced by the different race groups. African learners in particular were seriously disadvantaged in this regard. The issues of equity and redress were foremost in transformation of the education system, and the accompanying curriculum reform. This paper reports on equity in terms of equality of outputs and equality of inputs in South African school science, with a particular focus on the implementation of practical science investigations. This was a qualitative case study of two teachers on their implementation of science investigations at two schools, one a township school, previously designated for black children, and the other a former Model C school, previously reserved for white children. My study was guided by the curriculum implementation framework by Rogan and Grayson in trying to understand the practice of these teachers at schools located in contextually diverse communities. The framework helped profile the implementation of science investigations and also enabled me to explore the factors which are able to support or hinder this implementation.

    Escalation of non-communicable diseases (NCDs) among urban South African populations disproportionately afflicted by HIV/AIDS presents not only medical challenges but also new ways in which people understand and experience sickness. In Soweto, the psychological imprints of political violence of the Apartheid era and structural violence of HIV/AIDS have shaped social and health discourses. Yet, as NCDs increasingly become part of social and biomedical discussions in South African townships, new frames for elucidating sickness are emerging. This article employs the concept of syndemic suffering to critically examine how 27 women living with Type 2 diabetes in Soweto, a township adjacent to Johannesburg known for socio-economic mobility as well as inequality, experience and understand syndemic social and health problems. For example, women described how reconstructing families and raising grandchildren after losing children to AIDS was not only socially challenging but also affected how they ate, and how they accepted and managed their diabetes. Although previously diagnosed with diabetes, women illustrated how a myriad of social and health concerns shaped sickness. Many related diabetes treatment to shared AIDS nosologies, referring to diabetes as 'the same' or 'worse'. These narratives demonstrate how suffering weaves a social history where HIV becomes ordinary, and diabetes new.

    Background. Nephroblastoma is the commonest renal tumour seen in children. It has a good prognosis in developed countries with survival rates estimated to be between 80% and 90%, while in Africa it remains low. Method. Retrospective study of patients diagnosed with nephroblastoma who are seen at 4 paediatric oncology units, representing 58.5% of all South African children with nephroblastoma and treated following SIOP protocol between January 2000 and December 2010. Results. A total of 416 patients were seen at the 4 units. Over 80% of our patients were African and almost 10% of mixed ethnicity. The most common stage was stage 4. The median survival was 28 months after diagnosis with the mixed ethnicity patients recording the longest duration (39 months) and the white patients had the shortest median survival. The overall 5-year survival rate was estimated to be 66%. Stage 2 patients did significantly better (85%). Conclusions. Our patients are similar with regard to gender ratio, median age, and age distribution as described in the literature, but in South Africa the more advanced stage disease seen than in other developed countries is translated into low overall survival rate.

    Despite the documented relationship between hegemonic norms of masculinities and South African men's use of sexual violence, less is known about how women's engagement with norms of masculinity influences their agency in sexually coercive experiences. This study applied a narrative approach to assess how women's understandings of hegemonic male norms affected their perceptions of and responses to sexually coercive experiences. Twenty-five sexual history narrative interviews were conducted with women across five South African provinces representing a range of ages, language and sociocultural backgrounds. Interviews elicited stories of first experiences of sex and the range of sexual relationships through adulthood. Data were analysed using principles of thematic and narrative analysis. Coercive sexual experiences informed many women's normative ideas about men's sexuality including being impulsive, controlling and aggressive. This could underpin women's limited ability to exercise agency and their increased vulnerability to sexual abuse. Some women reported levels of trust and respect in subsequent relationships, which typically involved deconstructing norms of men's use of coercion and moving beyond self-blame and guilt. The findings highlight the need to appreciate the fluid and situated nature of women's agency from a relational perspective in terms of how women condone and challenge gender norms that support men's use of sexual violence in their relationships.

    This article explores the concept of spirituality within selected South African managerial work contexts. The aim of the study was to determine managers' perceptions of spirituality and health-related aspects in various South African workplaces. A phenomenological research paradigm was used, applying an in-depth qualitative research approach. The sample consisted of 12 senior managers from different organizations, including, for example, an international healthcare provider, an international auditing and consulting firm, a manufacturer of paint supplies and decorations and an ecclesiastical organization. Research methods included semi-structured interviews and observation. Data was analysed through content analysis, identifying themes, categories and codes. The findings indicate that spirituality promotes the development of health-related aspects of individuals, such as self-awareness, inner peace and the management of stress and depression. Managers emphasize that spirituality also has an impact on managing teams and teamwork, engaging in competitive behaviour, encouraging honesty and reducing selfishness. Based on the findings, a conclusion is given and practical as well as scientific recommendations are emphasized. In love lies the seed of our growth. The more we love, the closer we are to the spiritual experience. (Paulo Coelho, 1994). PMID:24953148

    Given that skeletal material recovered from medicolegal contexts is often incomplete or damaged, forensic anthropologists need to have a variety of techniques at their disposal in order to correctly determine the sex of unidentified human remains. The purpose of the present study, therefore, was to produce practical standards for discriminating the sex of black South Africans using measurements of the glenoid cavity of the scapula. Standardized digital photographs of the left glenoid fossa were taken for 60 males and 60 females drawn from the Pretoria Bone Collection. An image analysis software program was then used to collect height, breadth, area, and perimeter data from each digital photograph. All four dimensions of the glenoid cavity were highly sexually dimorphic in this population group (p < 0.0001). Univariate logistic regression analysis yielded overall sex prediction success rates ranging from 88.3% for area of the glenoid fossa to 85.8% for glenoid fossa breadth. Multivariate procedures did not provide increased accuracy over those using only a single variable. Classification sex biases were below 5.0% for all equations. These results demonstrate that the analysis of glenoid cavity size provides a highly accurate method for discriminating the sex of black South Africans. PMID:20814691
