Multicenter Study
Predictors of psychosocial adjustment in people with physical disease.
The purpose of this paper was to examine the demographic, medical and psychosocial variables that result in the deterioration of psychosocial adjustment in patients with physical disease, the meaning their illness has for them and their coping style. ⋯ The study indicated some predictors in the assessment of psychosocial adjustment and care of patients with physical illness. In daily clinical practice, among the patients with physical illness, those with a negative perception of their illness and those who define depression should be given special attention for psychosocial support.

Randomized Controlled Trial Multicenter Study Clinical Trial
Cost-effectiveness of voluntary HIV-1 counselling and testing in reducing sexual transmission of HIV-1 in Kenya and Tanzania.
Access to HIV-1 voluntary counselling and testing (VCT) is severely limited in less-developed countries. We undertook a multisite trial of HIV-1 VCT to assess its impact, cost, and cost-effectiveness in less-developed country settings. ⋯ HIV-1 VCT is highly cost-effective in urban east African settings, but slightly less so than interventions such as improvement of sexually transmitted disease services and universal provision of nevirapine to pregnant women in high-prevalence settings. With the targeting of VCT to populations with high HIV-1 prevalence and couples the cost-effectiveness of VCT is improved significantly.

Risk factors for severe respiratory syncytial virus infection leading to hospital admission in children in the Western Region of The Gambia.
Acute lower respiratory tract infections (ALRI) are the major cause of mortality and morbidity in young children worldwide. Respiratory syncytial virus (RSV) infection is the most important viral cause of severe ALRI but only a small proportion of children infected with this virus develop severe disease. To identify possible risk factors for severe RSV infection leading to hospital admission we have carried out a case-control study of Gambian children with RSV infection admitted to hospital. ⋯ Risk factors for severe RSV infection identified in this study are not amenable to public health interventions. Prevention of severe infection is likely to require the development of an effective vaccine.

Multicenter Study Clinical TrialEfficacy and safety of liposomal amphotericin B (AmBisome) for visceral leishmaniasis in endemic developing countries.
Reported are the results of a study to determine the efficacy and safety of liposomal amphotericin B (AmBisome) for treating visceral leishmaniasis (kala-azar) in several developing countries where the disease is endemic (Brazil, India, and Kenya). At each study site, sequential cohorts of 10 patients each were treated with AmBisome at a dose of 2 mg.kg-1.day-1 (2 MKD). The first cohort received regimen 1:2 MKD on days 1-6 and day 10 (total dose: 14 mg/kg). ⋯ In Brazil, regimen 1 was only partially curative: 5 of 13 patients (62%). Therefore, 15 patients were administered regimen 4 (2 MKD for 10 consecutive days; total dose, 20 mg/kg) and 13 patients were cured (83%). These results suggest that for the treatment of kala-azar the following doses of AmBisome should be administered: in India and Kenya, 2 mg/kg on days 1-4 and day 10; and in Brazil, 2 mg/kg on days 1-10.

Case-control study of oral contraceptives and risk of thromboembolic stroke: results from International Study on Oral Contraceptives and Health of Young Women.
To determine the influence of oral contraceptives (particularly those containing modern progestins) on the risk for ischaemic stroke in women aged 16-44 years. ⋯ Although there is a small relative risk of occlusive stroke for women of reproductive age who currently use oral contraceptives, the attributable risk is very small because the incidence in this age range is very low. There is no difference between the risk of oral contraceptives of the third and second generation; only first generation oral contraceptives seem to be associated with a higher risk. This small increase in risk may be further reduced by efforts to control cardiovascular risk factors, particularly high blood pressure.
