Examining the impact of HIV&AIDS on South African educators

Our aim in this study was to examine the impact of HIV&AIDS on South African educators. A cross-sectional survey was conducted in public schools combining HIV testing and a face-to-face interview with participants from a nationally representative sample of public educators. The results show that HIV is highly prevalent among South African public educators (12.7%) and the educators who are absent from school for longer periods (20 days or more) compared with those who are absent for less than four days have higher HIV prevalence (16.8% vs 11.95%). Educators also spend time away from teaching while they attend funerals for colleagues who have died (6.7%), for family members (13.4%) and for members of their communities (47.6%). This makes them feel depressed (71%). These results suggest that HIV&AIDS has an impact on the quality of education. There is a need to prevent new HIV infections and reduce morbidity through the implementation of comprehensive integrated prevention and treatment programmes targeted at educators. There is also a need to support educators in coping with the problem of HIV&AIDS at work and in the community

Family Planning Among Hiv Positive And Negative Clients In A Resource Poor Setting In South Africa

Objective: To investigate family planning needs, knowledge of HIV transmission and HIV disclosure in a cohort sample that had undergone PMTCT in a resource poor setting. Design. Cross-sectional survey. Setting: Five clinics implementing PMTCT from Qaukeni Local Service Area, O.R. Tambo District in the Eastern Cape. Subjects: The sample at postnatal care consisted of one postnatal interview (n= 1310) when the infants were aged three months or less (n= 141, 10.8%), 4-6 months (n=200, 15.3%), 7-12 months (n=785, 59.9%), or 13-18 months (n=183, 14.0%). Results: One hundred and sixteen women were found HIV positive, 642 HIV negative and 552 with unknown HlV status. Considering those with HIV test results, 15.3% were HIV positive. Almost four out of five women got counselling on safe sex during pregnancy but only two out of three women practiced safe sex during pregnancy. Postnatally, almost all women received counselling on family planning, yet use of contraceptives and condoms were low. HIV positive women used condoms more often than HIV negative women. HIV positive women were significantly more likely than HIV negative women to say that they did not intend to have more children. For HIV positive women PMTCT knowledge was a positive predictor for the intention to have a child, while age, having a partner, HIV disclosure to partner and number of children were not significant. Pregnancy desire did not differ between HIV positive and HIV negative women regarding marital status, having two or more live births and HIV disclosure. Conclusion: High pregnancy desires, low contraceptive and condom use were found among HIV positive women. The incorporation of HIV prevention into promotion of contraceptives by family planning programmes and service providers needs to be improved. East African Medical Journal Vol. 85 (3) 2008: pp. 20-2

New approaches, new activities and new outcomes in international conferences on HIV/AIDS in Africa – Report of the 3rd African Conference on the social aspects of HIV/AIDS, Dakar, 10 - 14 October 2005

Africa's HIV/AIDS situation remains cause for concern. The impact of HIV is considerable and threatens the survival and development of African societies. Although much has been attempted, the results still leave much to be desired. AIDS is an epidemic that needs to be addressed with much creativity and spirit of initiative. It is against this background that the 3rd African conference on the social aspects of HIV/AIDS brought innovations in the way international conferences are designed, activities implemented and results obtained. The innovations concerned the approach to international conferences and take into account reconceptualising HIV/AIDS so as to encourage holistic approaches and better visibility of vulnerable groups.The activities of the conference were organised in such a way as to get people living with HIV/AIDS (PLWHA), grassroots communities and marginalised groups to play a focal role.The conference offered an opportunity for developing cultural activities that would translate the African cultural concepts that had been identified as important in the HIV situation and response analysis. Interaction at the conference created an opportunity to analyse the various dimensions of the political, cultural and economic determinants. The conference offered food for thought around response construction while singling out the themes of urgency and acceleration of response, synergy construction, and coordination and conception of political responses.

How Solvent Dynamics Controls the Schlenk Equilibrium of Grignard Reagents: A Computational Study of CH₃MgCl in Tetrahydrofuran

The Schlenk equilibrium is a complex reaction governing the presence of multiple chemical species in solution of Grignard reagents. The full characterization at the molecular level of the transformation of CH₃MgCl into MgCl₂ and Mg(CH₃)₂ in tetrahydrofuran (THF) by means of ab initio molecular dynamics simulations with enhanced-sampling metadynamics is presented. The reaction occurs via formation of dinuclear species bridged by chlorine atoms. At room temperature, the different chemical species involved in the reaction accept multiple solvation structures, with two to four THF molecules that can coordinate the Mg atoms. The energy difference between all dinuclear solvated structures is lower than 5 kcal mol⁻¹. The solvent is shown to be a direct key player driving the Schlenk mechanism. In particular, this study illustrates how the most stable symmetrically solvated dinuclear species, (THF)CH₃Mg(μ-Cl)₂MgCH₃(THF) and (THF)CH₃Mg(μ-Cl)(μ-CH₃)MgCl(THF), need to evolve to less stable asymmetrically solvated species, (THF)CH₃Mg(μ-Cl)₂MgCH₃(THF)₂ and (THF)CH₃Mg(μ-Cl)(μ-CH₃)MgCl(THF)₂, in order to yield ligand exchange or product dissociation. In addition, the transferred ligands are always departing from an axial position of a pentacoordinated Mg atom. Thus, solvent dynamics is key to successive Mg–Cl and Mg–CH₃ bond cleavages because bond breaking occurs at the most solvated Mg atom and the formation of bonds takes place at the least solvated one. The dynamics of the solvent also contributes to keep relatively flat the free energy profile of the Schlenk equilibrium. These results shed light on one of the most used organometallic reagents whose structure in solvent remains experimentally unresolved. These results may also help to develop a more efficient catalyst for reactions involving these species

LAPW frozen-phonon calculation, shell model lattice dynamics and specific-heat measurement of SnO

An ab-initio Linear Augmented Plane-Wave (LAPW) calculation of the zone-centered phonon frequencies of SnO has been performed. E$_g$ symmetry has been ascribed to the mode observed at 113 cm$^{-1}$ in Raman measurements, discarding a previous B$_{1g}$ assignement. The other phonon modes measured by Raman spectroscopy are also well reproduced. A new shell-model has also been developed, that gives good agreement of the zone-centered frequencies compared to the measured data and the LAPW results. Specific heat measurements have been performed between 5 K and 110 K. Computation of the specific heat and the M\"{o}ssbauer recoilless fraction with the improved shell-model shows a good agreement with the experimental data as a function of temperature.Comment: 11 pages, 1 figure. to appear in Phys.

Screening and brief interventions for hazardous and harmful alcohol use among patients with active tuberculosis attending primary care clinics in South Africa: a cluster randomized controlled trial protocol

<p>Abstract</p> <p>Background</p> <p>In 2008 the World Health Organization (WHO) reported that South Africa had the highest tuberculosis (TB) incidence in the world. This high incidence rate is linked to a number of factors, including HIV co-infection and alcohol use disorders. The diagnosis and treatment package for TB and HIV co-infection is relatively well established in South Africa. However, because alcohol use disorders may present more insidiously, making it difficult to diagnose, those patients with active TB and misusing alcohol are not easily cured from TB. With this in mind, the primary purpose of this cluster randomized controlled trial is to provide screening for alcohol misuse and to test the efficacy of brief interventions in reducing alcohol intake in those patients with active TB found to be misusing alcohol in primary health care clinics in three provinces in South Africa.</p> <p>Methods/Design</p> <p>Within each of the three selected health districts with the highest TB burden in South Africa, 14 primary health care clinics with the highest TB caseloads will be selected. Those agreeing to participate will be stratified according to TB treatment caseload and the type of facility (clinic or community health centre). Within strata from 14 primary care facilities, 7 will be randomly selected into intervention and 7 to control study clinics (42 clinics, 21 intervention clinics and 21 control clinics). At the clinic level systematic sampling will be used to recruit newly diagnosed TB patients. Those consenting will be screened for alcohol misuse using the AUDIT. Patients who screen positive for alcohol misuse over a 6-month period will be given either a brief intervention based on the Information-Motivation-Behavioural Skills (IMB) Model or an alcohol use health education leaflet.</p> <p>A total sample size of 520 is expected.</p> <p>Discussion</p> <p>The trial will evaluate the impact of alcohol screening and brief interventions for patients with active TB in primary care settings in South Africa. The findings will impact public health and will enable the health ministry to formulate policy related to comprehensive treatment for TB and alcohol misuse, which will result in reduction in alcohol use and ultimately improve the TB cure rates.</p> <p>Trial registration number</p> <p>PACTR: <a href="http://apps.who.int/trialsearch/trial.aspx?trialid=PACTR201105000297151">PACTR201105000297151</a></p

Patient experiences and health system responsiveness in South Africa

<p>Abstract</p> <p>Background</p> <p>Patients' views are being given more and more importance in policy-making. Understanding populations' perceptions of quality of care is critical to developing measures to increase the utilization of primary health care services. Using the data from the South African <it>World Health Survey </it>(WHS), the current study aims to evaluate the degree of health care service responsiveness (both out-patient and in-patient) and comparing experiences of individuals who used public and private services in South Africa.</p> <p>Methods</p> <p>A population-based survey of 2352 participants (1116 men and 1236 women) was conducted in South Africa in 2003, the WHS – as part of a World Health Organization (WHO) project focused on health system performance assessment in member countries.</p> <p>Results</p> <p>Health care utilization was among those who attended in-patient care 72.2% attended a public and 24.3% a private facility, and of those who attended out-patient care 58.7% attended a public and 35.7% a private facility. Major components identified for out-patient care responsiveness in this survey were highly correlated with health care access, communication and autonomy, secondarily to dignity, confidentiality and quality of basic amenities, and thirdly to health problem solution. The degree of responsiveness with publicly provided care was in this study significantly lower than in private health care. Overall patient non-responsiveness for the public out-patient service was 16.8% and 3.2% for private care. Discrimination was also one of the principal reasons for non-responsiveness in all aspects of provided health care.</p> <p>Conclusion</p> <p>Health care access, communication, autonomy, and discriminatory experiences were identified as priority areas for actions to improve responsiveness of health care services in South Africa.</p

The association of nutrition behaviors and physical activity with general and central obesity in Caribbean undergraduate students

Objective. To quantify the prevalence of obesity and obesity-related factors in a cross-sectional, observational study of Caribbean students using the results of three recent surveys of health behavior among undergraduates in Barbados, Grenada, and Jamaica. Methods. A total of 1578 Caribbean undergraduate students from Barbados, Grenada, and Jamaica (ages 18.30 years) completed questionnaires and had physical measurements recorded. Multivariable logistic regression was used to estimate odds ratios (ORs) for the association of nutrition behaviors with prevalence of obesity (body mass index ≥ 30 kg/m2); elevated waist-to-height ratio (W/ht) (> 0.50); and high waist circumference (WC) (> 88 cm in females, > 102 cm in males). Models were adjusted for age, year in university, socioeconomic status, and sex. Results. There was a higher prevalence of obesity (13% versus 10%), high WC (21% versus 7%), and high W/ht (35% versus 25%) in females relative to males. Compared to females, males had reduced odds of obesity (OR 0.46), high WC (OR 0.22), and high W/ht (OR 0.61) (P < 0.05 for all). Both females (46%) and males (24%) reported high levels of physical inactivity. Fruit and vegetable consumption was low (approximately two servings per day). Many students reported avoiding fatty foods (40%); this behavior was associated with high W/ht (OR 1.68), obesity (OR 1.90), and high WC (OR 1.82) (P < 0.05 for all). Irregular breakfast consumption, age, and year of study were also positively associated with obesity. Physical activity was not significantly associated with any obesity measure. Conclusions. There was a low prevalence of healthy behaviors and a high prevalence of obesity in this sample of Caribbean young adults
