RESUMO

While disclosure of HIV sero-status is encouraged in the management of the HIV and AIDS epidemic; it remains a challenge; especially among family members. This article examines the moral dilemmas and pragmatic incentives surrounding disclosure of HIV status in contemporary Uganda. Our findings are based on 12 in-depth interviews; 2 focus-group discussions; 6 key informant interviews with AIDS activists; and open-ended responses derived from 148 HIV-positive persons in a quantitative survey. The study was conducted in 2008-2009 in Kampala; Mpigi; and Soroti districts in Uganda. We found both parents and adult children facing dilemmas in disclosure; whether it was parents revealing their own HIV status to their children or the status of their perinatally infected children; or young people infected through sexual intercourse telling their parents. For both groups; there is fear of blame; stigma; discrimination; and shame and guilt related to unsafe sex; while young people also fear loss of privileges. On the other hand; there are practical imperatives for disclosure in terms of gaining access to care; treatment; and material resources. Faced with these dilemmas; HIV-positive people and their families require professional counselling to help them work through the emotional challenges encountered and identify mechanisms of support and coping

RESUMO

Adherence levels in Africa have been found to be better than those in the US. However around one out of four ART users fail to achieve optimal adherence, risking drug resistance and negative treatment outcomes. A high demand for 2nd line treatments (currently ten times more expensive than 1st line ART) undermines the sustainability of African ART programs. There is an urgent need to identify context-specific constraints to adherence and implement interventions to address them. We used rapid appraisals (involving mainly qualitative methods) to find out why and when people do not adhere to ART in Uganda, Tanzania and Botswana. Multidisciplinary teams of researchers and local health professionals conducted the studies, involving a total of 54 semi-structured interviews with health workers, 73 semi-structured interviews with ARTusers and other key informants, 34 focus group discussions, and 218 exit interviews with ART users. All the facilities studied in Botswana, Tanzania and Uganda provide ARVs free of charge, but ART users report other related costs (e.g. transport expenditures, registration and user fees at the private health facilities, and lost wages due to long waiting times) as main obstacles to optimal adherence. Side effects and hunger in the initial treatment phase are an added concern. We further found that ART users find it hard to take their drugs when they are among people to whom they have not disclosed their HIV status, such as co-workers and friends. The research teams recommend that (i) health care workers inform patients better about adverse effects; (ii) ART programmes provide transport and food support to patients who are too poor to pay; (iii) recurrent costs to users be reduced by providing three-months, rather than the one-month refills once optimal adherence levels have been achieved; and (iv) pharmacists play an important role in this follow-up care.

RESUMO

The ABC strategy is credited for bringing the HIV/AIDS epidemic under control in Uganda. By promoting abstinence, being faithful, and condom use, safe(r) behaviours have been identified that are applicable to people in different circumstances. However, scaling-up of antiretroviral therapy in the country raised concerns that HIV prevention messages targeting the uninfected population are not taking sufficient account of inherent complexities. Furthermore, there is debate in the country over relative importance of abstinence in reduction of HIV incidence as well as over the morality and effectiveness of condoms. The purpose of this paper is to examine each component of ABC in light of current developments. It is argued that there is still a strong justification for condom use to complement abstinence and being faithful. There is an urgent need to update and relaunch Uganda's ABC strategy--its three elements are complementary, synergistic, and inseparable in the national HIV prevention programme.

RESUMO

BACKGROUND: Treatment of sexually-transmitted infections (STIs) and behavioural interventions are the main methods to prevent HIV in developing countries. We aimed to assess the effect of these interventions on incidence of HIV-1 and other sexually-transmitted infections. METHODS: We randomly allocated all adults living in 18 communities in rural Uganda to receive behavioural interventions alone (group A), behavioural and STI interventions (group B), or routine government health services and community development activities (group C). The primary outcome was HIV-1 incidence. Secondary outcomes were incidence of herpes simplex virus type 2 (HSV2) and active syphilis and prevalence of gonorrhoea, chlamydia, reported genital ulcers, reported genital discharge, and markers of behavioural change. Analysis was per protocol. FINDINGS: Compared with group C, the incidence rate ratio of HIV-1 was 0.94 (0.60-1.45, p=0.72) in group A and 1.00 (0.63-1.58, p=0.98) in group B, and the prevalence ratio of use of condoms with last casual partner was 1.12 (95% CI 0.99-1.25) in group A and 1.27 (1.02-1.56) in group B. Incidence of HSV2 was lower in group A than in group C (incidence rate ratio 0.65, 0.53-0.80) and incidence of active syphilis for high rapid plasma reagent test titre and prevalence of gonorrhoea were both lower in group B than in group C (active syphilis incidence rate ratio, 0.52, 0.27-0.98; gonorrhoea prevalence ratio, 0.25, 0.10-0.64). INTERPRETATION: The interventions we used were insufficient to reduce HIV-1 incidence in rural Uganda, where secular changes are occurring. More effective STI and behavioural interventions need to be developed for HIV control in mature epidemics.

RESUMO

This paper describes the implementation of a large community-based HIV/AIDS behavioural intervention in rural Uganda and presents 4 years' worth of quantitative process data. The intervention involved 560 field-based workers (57% male, 76% subsistence farmers, mean age 35 years), supervised by six central staff. Intervention channels included drama and video shows, Community Educators (CEs), as well as leaflet and condom distribution. Activities focused on one or more of 16 key topics. In total, 392 000 attendances (51% female) were recorded--a mean of over 6 for each of the 64 000 target adults--at 81 000 activities, with CEs attracting 71% of the total attendance; 164 000 leaflets and 242 000 condoms were also distributed. The annual cost of the intervention per target individual was approximately US$1.76. Our voluntary workforce experienced an annual attrition rate of 11%, with 'stable' workers more likely to be older, married or opinion leaders in their community than those who dropped out. We calculate that even a significant increase in the proportion of female field workers would have made little difference either to the sex ratio of attendees or to overall attendance. In spite of some initial resistance to the intervention, particularly in relation to condoms, we have demonstrated that people in rural Africa can accept and actively participate in the dissemination of HIV/AIDS prevention messages throughout their own communities.

RESUMO

A cross-sectional questionnaire survey examining knowledge, attitudes and intended use of condoms was conducted among 1,821 pupils (mean age = 14.2 years, range = 9--24) from 27 primary and secondary schools in rural south western Uganda. Condom education is not provided in Ugandan schools, but both boys and girls had relatively high overall levels of knowledge, even though boys demonstrated a higher level than girls. This suggests that respondents had successfully obtained reliable information from other sources. Boys and girls had similar and fairly positive attitudes towards condoms, although considerable shyness was expressed, both about discussing condoms with a partner and buying them. Fifty-eight per cent said that they themselves would use a condom if one were available, but girls were far less likely than boys to say so. Roman Catholics (46% of the sample) were less knowledgeable and less positive about condoms than non-Catholics, and the boys in this group, but not the girls, were also much less likely to say they would use one. Possible interventions based on these findings are discussed, and a research agenda for the delivery of assertiveness training to girls is proposed.

RESUMO

A 19 activity extracurricular school-based AIDS education programme lasting 1 year was conducted in rural southwestern Uganda using specially trained teachers, and was evaluated using mutually supportive quantitative and qualitative methods. In total, 1274 students from 20 intervention schools and 803 students from 11 control schools completed questionnaires at baseline, and their classes were followed up. In addition, 93 students from five of the intervention schools participated in 12 focus group discussions. The programme had very little effect--seven of the nine key questionnaire variables showed no significant increase in score after the intervention. Data from the focus group discussions suggest that the programme was incompletely implemented, and that key activities such as condoms and the role-play exercises were covered only very superficially. The main reasons for this were a shortage of classroom time, as well as teachers' fear of controversy and the unfamiliar. We conclude that large-scale comprehensive school-based AIDS education programmes in sub-Saharan Africa may be more completely implemented if they are fully incorporated into national curricula and examined as part of life-skills education. This would require teachers to be trained in participatory teaching methods while still at training college.

RESUMO

The objective of the study was to explore how school-going adolescents in south-western Uganda negotiate sexual relationships. Qualitative data were obtained from 15 boys and 15 girls (14-18 years old), during a series of role plays, focus group discussions and one-to-one interviews. A questionnaire was administered to 80 pupils (12-20 years old) from the same school. Most of the pupils were sexually active. Sexual relationships between boys and girls were mediated by peers. Boys initiated relationships. Exchange played an important role in the negotiation of sexual relationships. Money or gifts were given and received in exchange for sexual favours and to strengthen the relationship. To maximize gains, some adolescents had sexual relationships with adults. Sexual relationships were characterized by ambiguity. Love is intertwined with sexual desire, money and prestige. Girls have to be explicit enough to get a good deal; if they are too explicit they will be stigmatized as 'loose' but if they are not interested in money they may be suspected of wanting to spread HIV. Boys try to persuade girls that they have money, but do not want to emphasize this too much. In sexual negotiations a boy must persuade a girl that although he is modern and sophisticated (i.e. experienced) he does not chase after every girl; the girl does not want to come over as an unsophisticated virgin, but does not want to give the impression that she is loose either. There is a tension between the traditional ideal of female chastity and submissiveness and the modern image of sexual freedom. Multiple partnerships were highly valued as a sign of sophistication. Condoms were not considered important. Interventions aimed at reducing the spread of HIV do not seem to be having an effect on the behaviour of this group of adolescents. On the contrary, risky attitudes and behaviour are part of an adolescent ideal of modernity and sophistication. New approaches are needed to persuade this group of the need for change. Shifting the source of interventions from adults to the adolescents themselves, encouraging girls to try other means of earning money and debunking the idea that having many partners is sophisticated may be productive alternatives.

RESUMO

A recent article in Nature, "Soil Fertility Limits Carbon Sequestration by Forest Ecosystems in a CO2-Enriched Atmosphere" by Oren and colleagues, has been widely reported on, and often misinterpreted, by the press. The article dampens enthusiasm for accelerated forest growth due to CO2 fertilization and puts in question the fringe theory that the world"s forests can provide an automatic mitigation feedback. We agree that these results increase our understanding of the global carbon cycle. At the same time, their relevance in the context of the international climate change negotiations is much more complicated than portrayed by newspapers such as the New York Times ("Role of Trees in Curbing Greenhouse Gases is Challenged", May 24, 2001) and the Christian Science Monitor ("Trees No Savior for Global Warming", May 25, 2001).

RESUMO

Malpractice lawsuits filed against educators are a relatively new phenomenon. These suits have met with considerable resistance from the courts, which prefer not to involve themselves in assessing the quality of educational services. However, educators in the health professions are more susceptible to legal action because courts are more likely to recognize claims based on medical malpractice. This article reviews the case law regarding negligence as a basis for educational malpractice and suggests ways educators can avoid such litigation.

RESUMO

PIP: To explore the socializing influences which have shaped rural adolescent schoolgirls' views and values about sex in a high HIV prevalence area of Uganda, detailed qualitative data were obtained over a 1-year period from 15 schoolgirls aged 14-17 years. The girls were chosen for their willingness to participate actively in a series of role plays, focus group discussions, and one-to-one interviews. Results indicated that the girls have been subjected to a wide range of influences, including parents, social functions, other young children, nature, their paternal aunt, peers, school, and various media, such as pornography. Moreover, there was disagreement about the relative values of sex and virginity. Some were determined to retain their virginity but the majority felt that sex benefits them socially and personally. Notably, peer pressure was a major factor influencing the opinions of many girls, while traditional influences are in decline. Given the small sample size of the study, care should be taken in generalizing from the results. However, the data suggest that sex has a high value for at least a substantial minority of adolescent girls in rural Misaka, Uganda. Policy makers and health educators should therefore consider how best to devise safe messages about sex that are relevant and applicable to this vulnerable segment of the population.^ieng

RESUMO

As part of a large IEC (Information, Education and Communication)/STD intervention trial, a 19-lesson, comprehensive school-based AIDS education programme was implemented and evaluated in 50 primary and 16 secondary schools in 12 parishes of Masaka District, Uganda. A series of three teacher-training and evaluation workshops spread over a year was held in each parish, between which teachers implemented the programme in the classroom. One hundred and forty-eight teachers were trained and about 3,500 students were subsequently exposed to the programme. Both teachers and students responded positively, which suggests that this type of programme has much to offer young people who attend school. However, some problems were encountered: language, programme content, community resistance to teaching about condoms, and several practical issues. Proposed solutions include flexibility with the English language policy, alternative approaches to role play activities, targeting influential individuals with information about the need for young people to learn about safer sex, and a parallel community-based IEC programme to facilitate community acceptance of the need for the programme. In addition, implementation may be incomplete unless comprehensive AIDS education is fully incorporated into the curriculum, and properly examined. These findings are placed in the context of other life skills/AIDS education programmes being introduced both in Uganda and elsewhere in Africa.


PIP: This paper presents a comprehensive teacher-based AIDS education program that was implemented in 50 primary and 16 secondary schools in Masaka District, Uganda. An education program produced by WHO/UN Educational, Scientific and Cultural Organization was used which contained 53 English language student activities and related teachers' guides. 19 activities were chosen for the Masaka trial that would cover 15-20 hours of classroom time. A total of 148 teachers were trained and about 3500 students (85% fell within the target age range of 12-16 years) were exposed to the program. The program received positive response from both teachers and students. However, there were some problems encountered which included language difficulties, program content, and community resistance to teaching about condoms. There was a limited discussion of condoms in class because parents, religious sectors opposed it, and by teachers themselves who believe that condoms promote promiscuity. In addition, practical problems were also experienced such as time constraints, teacher attrition, sexual harassment of schoolgirls by some male teachers, and limited transportation and communication. The proposed solutions included flexibility with the English language policy, targeting influential individuals with information about the need for young people to learn about safer sex and a parallel community-based program to facilitate community acceptance of the need for the program. Finally, the benefits of this program range from reduction of HIV transmission and unwanted pregnancies, to improved communication between sexual partners that is accompanied by an enhanced mental well-being.

RESUMO

Free radicals such as superoxide (.O2-) produced by xanthine oxidase might cause cell death during reperfusion after myocardial ischemia. The effect of the xanthine oxidase inhibitor allopurinol on infarct size in ischemia-reperfusion models has been variable, possibly because of differences in treatment duration. Adequate inhibition of xanthine oxidase may require a sufficient pretreatment period to permit conversion of allopurinol to oxypurinol, the actual inhibitor of superoxide production. To test more definitively whether xanthine oxidase-derived free radicals cause cell death during reperfusion, the effect of oxypurinol on infarct size was evaluated in an ischemia-reperfusion model. Open chest dogs underwent 40 min of circumflex coronary artery occlusion followed by reperfusion for 4 days. Twelve dogs were treated with oxypurinol (10 mg/kg body weight intravenously 10 min before occlusion and 10 mg/kg intravenously 10 min before reperfusion) and 11 control dogs received drug vehicle alone (pH 10 normal saline solution). Nine control dogs from a concurrent study also were included. Infarct size was measured histologically and analyzed with respect to its major baseline predictors, including anatomic area at risk and collateral blood flow (measured with radioactive microspheres). Infarct size as a percent of the area at risk averaged 23.8 +/- 2.7% (mean +/- SEM) in the oxypurinol group (n = 10) and 23.1 +/- 4.2% in the control group (n = 17) (p = NS). Collateral blood flow to the inner two thirds of the ischemic wall averaged 0.08 +/- 0.01 ml/min per g in the oxypurinol group and 0.09 +/- 0.02 ml/min per g in the control group.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

In this study, alternative dose-response equations for assessing the effects of O3 on soybeans (Glycine max (L.) Merr.) were established. For each of three soybean cultivars, three models (linear, quadratic, and Weibull) were fitted to relate different measures of O3 dose, during the soybean flowering maturity period, to the soybean yield. The dose measures were 7-h (9:00 a.m. to 4:00 p.m.) and 12-h (7:00 a.m. to 7:00 p.m.) means, 7-h and 12-h total doses, and the 90th and 75th percentile O3 concentrations. Using data for primarily rural and small city O3 monitoring sites, county-level O3 doses were calculated, and soybean losses due to O3 were predicted for Illinois, Kentucky, and Virginia. The sensitivity of O3-induced soybean loss predictions to model forms and inputs was determined with regard to: (1) inter-year differences in ambient O3, (2) differences among the six dose measures, (3) differences among the three different model forms, (4) the impact of the agricultural practice of double-cropped soybean production, and (5) variance in response to O3 among three different soybean cultivars.
