RESUMO

AIMS: An updated Cochrane systematic review assessed effectiveness of screening and brief intervention to reduce hazardous or harmful alcohol consumption in general practice or emergency care settings. This paper summarises the implications of the review for clinicians. METHODS: Cochrane methods were followed. Reporting accords with PRISMA guidance. We searched multiple resources to September 2017, seeking randomised controlled trials of brief interventions to reduce hazardous or harmful alcohol consumption in people attending general practice, emergency care or other primary care settings for reasons other than alcohol treatment. Brief intervention was defined as a conversation comprising five or fewer sessions of brief advice or brief lifestyle counselling and a total duration of less than 60 min. Our primary outcome was alcohol consumption, measured as or convertible to grams per week. We conducted meta-analyses to assess change in consumption, and subgroup analyses to explore the impact of participant and intervention characteristics. RESULTS: We included 69 studies, of which 42 were added for this update. Most studies (88%) compared brief intervention to control. The primary meta-analysis included 34 studies and provided moderate-quality evidence that brief intervention reduced consumption compared to control after one year (mean difference -20 g/wk, 95% confidence interval -28 to -12). Subgroup analysis showed a similar effect for men and women. CONCLUSIONS: Brief interventions can reduce harmful and hazardous alcohol consumption in men and women. Short, advice-based interventions may be as effective as extended, counselling-based interventions for patients with harmful levels of alcohol use who are presenting for the first time in a primary care setting.

RESUMO

BACKGROUND: Oral candidiasis (OC) associated with human immunodeficiency virus (HIV) infection occurs commonly and recurs frequently, often presenting as an initial manifestation of the disease. Left untreated these lesions contribute considerably to the morbidity associated with HIV infection. Interventions aimed at preventing and treating HIV-associated oral candidal lesions form an integral component of maintaining the quality of life for affected individuals. OBJECTIVES: To determine the effects of any intervention in preventing or treating OC in children and adults with HIV infection. SEARCH STRATEGY: The search strategy was based on that of the HIV/AIDS Cochrane Review Group. The following electronic databases were searched for randomised controlled trials for the years 1982 to 2005: Medline; AIDSearch; EMBASE and CINAHL. The Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effectiveness and the Cochrane Central Register of Controlled Trials (CENTRAL) was also searched through May 2005. The abstracts of relevant conferences, including the International Conferences on AIDS and the Conference on Retroviruses and Opportunistic Infections, as indexed by AIDSLINE, were also reviewed. The strategy was iterative, in that references of included studies were searched for additional references. All languages were included. SELECTION CRITERIA: Randomised controlled trials (RCTs) of palliative, preventative or curative therapy were considered, irrespective of whether the control group received a placebo. Participants were HIV positive adults. DATA COLLECTION AND ANALYSIS: Two authors independently assessed the methodological quality of the trials and extracted data. Study authors were contacted for additional data where necessary. MAIN RESULTS: Four trials were conducted in developing countries with eleven of the trials conducted in the United States of America. Twenty eight trials (n=3225) were included. Nineteen trials investigated treatment and nine trials the prevention of OC. One trial, comparing fluconazole and ketoconazole, investigated the treatment of OC in children. Eighteen of the included studies reported CD4 cell counts. None of the included studies investigated the effects of HAART or any other form of antiretroviral treatment on OC treatment or prevention.TreatmentTreatment was assessed in the majority of trials looking at both clinical and mycological cures. In the majority of comparisons there was only one trial. Compared to nystatin, fluconazole favoured clinical cure in adults(1 RCT; n=167; RR 1.69; 95% CI 1.27 to 2.23). There was no difference with regard to clinical cure between fluconazole compared to ketoconazole (2 RCTs; n=83; RR 1.27; 95% CI 0.97 to 1.66), itraconazole (2 RCTs; n=434; RR 1.05; 95% CI 0.94 to 1.16) or clotrimazole (2 RCTs; n=358; RR 1.14; 95% CI 0.92 to 1.42). When compared with clotrimazole, both fluconazole (2 RCTs; n=358; RR 1.47; 95% CI 1.16 to 1.87) and itraconazole (1 RCT; n=123; RR 2.20; 95% CI 1.43 to3.39) proved to be better for mycological cure. Both gentian violet (1 RCT; n=96; RR 5.28; 95% CI 1.23 to 22.55) and ketoconazole (1 RCT; n=92; RR 5.22; 95% CI 1.21 to 22.53) were superior to nystatin in bringing about clinical cure. PreventionSuccessful prevention was defined as the prevention of a relapse while receiving prophylaxis. Fluconazole was compared with placebo in one trial (5 RCTs; n=599; RR 0.61; 95% CI 0.5 to 0.74) and with no treatment in another (1 RCT; n=65; RR 0.16; 95% CI 0.08 to 0.34). In both instances the prevention of clinical episodes was favoured by fluconazole. Comparing continuous fluconazole treatment with intermittent treatment (1 RCT; n=62; RR 0.37; 95% CI 0.15 to 0.92), prevention is favoured by the continuous treatment. AUTHORS' CONCLUSIONS: Implications for practiceDue to only one study in children it is not possible to make recommendations for treatment or prevention of OC in children. Amongst adults, there were few studies per comparison. Due to insufficient evidence no conclusion could be made about the effectiveness of clotrimazole, nystatin, amphotericin B, itraconazole or ketoconazole with regard to OC prophylaxis. In comparison to placebo, fluconazole is an effective preventative intervention. However, the potential for resistant Candida organisms to develop, as well as the cost of prophylaxis, might impact the feasibility of implementation. No studies were found comparing fluconazole with other interventions. Direction of findings suggests that ketoconazole, fluconazole, itraconazole and clotrimazole improved the treatment outcomes. Implications for researchThere is an urgent need for gentian violet and other less expensive anti-fungal drugs for OC treatment to be evaluated in larger studies. More well designed treatment trials with larger sample size are needed to allow for sufficient power to detect differences in not only clinical, but also mycological response and relapse rates. There is also a strong need for more research to be done on the treatment and prevention of OC in children as it is reported that OC is the most frequent fungal infection in children and adolescents who are HIV positive. More research on the effectiveness of less expensive interventions also needs to be done in resource-poor settings. Currently few trials report outcomes related to quality of life, nutrition, or survival. Future researchers should consider measuring these when planning trials. Development of resistance remains under-studied and more work must be done in this area. It is recommended that trials be more standardised and conform more closely to CONSORT as this will improve research and also clinical practice.

RESUMO

OBJECTIVE: To describe randomised controlled trials (RCTs) published in the South African Medical Journal (SAMJ) over a 50-year period from 1948 to 1997 with regard to number, topic and quality. METHODS: We hand searched all issues of the SAMJ published during the study period to identify all published RCTs. OUTCOME MEASURES: Number, topic and quality of RCTs published from 1948 to 1997. RESULTS: Eight hundred and fifty-eight clinical trials were published during the period reviewed. Eighty-four per cent of RCTs were published as full articles. During the 1980s the number of RCTs published increased rapidly, with a peak of 35 in 1985, but then declined to only 5 in 1997. The majority (92%) of RCTs were conducted in a hospital setting. A varied range of subjects was covered, with gastroenterology taking the lead and no trials in public health. The sample size in more than 50% of RCTs was smaller than 50 patients. Fifty-one per cent (435 trials) used random allocation and 49% (423) quasi-random methods of allocation. Concealment of treatment allocation was judged to be adequate in 46% of studies (N = 200), blinding of observers assessing outcomes was adequate in 28% (123), and all the allocated test subjects were included in the primary analysis in 28% (123). The follow-up period was more than 1 year in 4% (17) and less than 6 days in 16% (71). CONCLUSIONS: Compared with other international journals the SAMJ is highly regarded in terms of the number of trials published. There are, however, a number of deficiencies in the quality of the trials.

RESUMO

The South African Medical Research Council (MRC) has provided access to on-line health and biomedical information since 1976, when the MRC became an international partner of NLM. This was done to support research and health care when the Institute of Biomedical Communication was established. The institute has since reorganized and is now the Information Systems Division in the Research Systems Support Group MRC. he MRC and medical libraries in South Africa are able to access various automated services via telecommunication. The major systems available are MEDLARS, DIALOG, DATASTAR and BRS, with ECRI being the latest addition; most used are MEDLARS and DIALOG. New technologies (e.g., CD-ROM) have given more people access. This technology is not available to many people working in Primary Health Care (PHC), as they do not have access to computer networks. Beyond on-line is statistical and printed information, called "Gray Literature," not accessible through on-line systems as it is not published in conventional sources used to build databases. With a shift to Essential National Health Research and the focus on PHC and preventative medicine, demand for health information and "gray literature" is growing. The MRC collects and produces this material and has its own database called SAMED, which is to be made available to others as our contribution to health. It is hoped to make this available for inclusion in the proposed African Index Medicus presently investigated by the World Health Organization. Africa as a continent, and South Africa as a country, are experiencing major changes in health care and medical practice, and inevitably, provision of health information services. With South Africa's re-entry into the global village and its acceptance by the rest of Africa, it can be a key player in information provision to the rest of the continent. The MRC, as a major provider of Health information, can play a vital role in the information flow throughout Africa by continuously improving and expanding its services. A large proportion of South Africans live in rural areas where health care is provided by clinics not linked to information networks. This does not mean these clinics are excluded from the use of information. The major challenge is to find the ways and means of getting the relevant information to these clinics. Information is needed to help with patient care and continuing education. With this in mind, the MRC is evaluating different formats in which information can be supplied. Due to the lack of computer literacy, facilities, and financial constraints, it is better to supply printed information. With the spread of technology through the country and continent, it can be assumed that information flow and transfer will be more rapid. Repackaging of information means that it is possible to get the relevant information to the right people at the right time. The first such package developed is for hospital managers. With the help from experts in the field of PHC, it is hoped to develop packages aimed specifically at the CHWs and other workers in the field. All packages developed by the MRC are backed by a document provision service, using the most cost-effective route to obtain documents. A printed product must comply with certain criteria; these are: 1) purpose for which the information is needed; 2) kind of information needed and the format in which it is needed; 3) when the information is needed; 4) is the information to be supplied on an ongoing basis i.e., updated with latest information; 5) cost involved; and 6) how to get the information to the relevant user.
