Glucocorticoid-induced hyperglycaemia in respiratory disease: a systematic review and meta-analysis.

The relative risk of glucocorticoid-induced hyperglycaemia is poorly quantified. We undertook a meta-analysis to estimate the association between glucocorticoid treatment and hyperglycaemia, overall and separately in individuals with and without diabetes and underlying respiratory disease. We searched electronic databases for clinical trials of adults randomized to either glucocorticoid treatment or placebo. Eight articles comprising 2121 participants were identified. We performed a random effects meta-analysis to determine relative risks for the associations between glucocorticoid use and both hyperglycaemia and starting hypoglycaemic therapy. In all individuals, the relative risk of hyperglycaemia comparing glucocorticoid treatment with placebo was 1.72 [95% confidence interval (CI) 1.50-2.04; p < .001]. The relative risks in individuals with and those without diabetes were 2.10 (95% CI 0.92-5.02; p = .079) and 1.50 (95% CI 0.79-2.86; p = .22), respectively. In all individuals, the relative risk of hyperglycaemia requiring initiation of hypoglycaemic therapy, comparing glucocorticoid treatment with placebo, was 1.73 (95% CI 1.40-2.14; p < .001). In conclusion, glucocorticoid therapy increases the risk of hyperglycaemia in all individuals with underlying respiratory disease but not when diabetic status is analysed separately.

Prevalence of rheumatic valvular heart disease in Rwandan school children: echocardiographic evaluation using the World Heart Federation criteria.

BACKGROUND: Rheumatic fever (RF) and rheumatic valvular heart disease (RHD) remain important medical, surgical and public health concerns in many parts of the world, especially in sub-Saharan Africa. However, there are no published data from Rwanda. We performed a RHD prevalence study in a randomly selected sample of Rwandan school children using the 2012 World Heart Federation (WHF) criteria. METHODS: Echocardiographic assessment of 2 501 Rwandan school children from 10 schools in the Gasabo district near Kigali was carried out. Resulting data were evaluated by four experienced echocardiographers. Statistical analyses were carried out by statisticians. RESULTS: RHD prevalence was 6.8/1 000 children examined (95% CI: 4.2/1 000-10.9/1 000). Seventeen met WHF criteria for RHD, 13 fulfilled criteria for 'borderline' RHD and four were 'definite' RHD. None of these 17 had been previously identified. CONCLUSION: These data indicate a significant burden of RHD in Rwanda and support a need for defined public health RF control programmes in children there.

Adolescent violence. Assessment of nurses' attitudes and educational needs.

Adolescent violence is a major public health problem. Because of their roles in community and hospital settings, nurses have an opportunity to limit the epidemic of violence. The purpose of this study was to examine the perceived levels of knowledge, the value of further education, resource utilization, and attitudes of nurses caring for adolescent victims of violence. Data were collected from 60 nurses employed at an urban public hospital. Results of the study indicate that 50% of the respondents had high scores on the perceived knowledge section of the survey. However, the majority of nurses (82.5%) felt inadequately educated about violence. The attitudes reported with the most frequency were frustration (78%), anger (59%), and powerlessness (58%). The results of this study indicate a need for additional violence education for nurses, particularly in the areas of available resources and intervention for adolescent victims of violence.
