ReviewImpact of tuberculosis preventive therapy on tuberculosis and mortality in HIV-infected children.
Children with HIV are at increased risk of acquiring tuberculosis (TB), a common cause of acute and chronic respiratory disease and death in HIV-infected children living in areas where prevalence of the disease is high. Children infected with HIV and TB have worse outcomes than HIV-uninfected children who have TB; thus, preventing the infection and disease in HIV-infected children is potentially an important public health intervention. Isoniazid, an anti-tuberculosis medication, has been used effectively to prevent TB in HIV-uninfected children, but currently there are no guidelines on the use of TB preventive therapy in HIV-infected children. ⋯ Isoniazid prophylaxis in HIV-infected children has the potential to play a major public health role by reducing TB incidence and death. As yet, however, data are insufficient to guide the duration of prophylaxis and to support its use in children using highly active antiretroviral therapy (HAART) and in those living in areas of low TB prevalence. Further studies are needed to assess whether TB preventive therapy is of benefit in all HIV-infected children, irrespective of use of antiretroviral treatment, the optimal duration of preventive therapy, or long-term adverse events.

Review Meta AnalysisSertraline versus other antidepressive agents for depression.
The National Institute for Health and Clinical Excellence clinical practice guideline on the treatment of depressive disorder recommended that selective serotonin reuptake inhibitors should be the first-line option when drug therapy is indicated for a depressive episode. Preliminary evidence suggested that sertraline might be slightly superior in terms of effectiveness. ⋯ This systematic review and meta-analysis highlighted a trend in favour of sertraline over other antidepressive agents both in terms of efficacy and acceptability, using 95% confidence intervals and a conservative approach, with a random effects analysis. However, the included studies did not report on all the outcomes that were pre-specified in the protocol of this review. Outcomes of clear relevance to patients and clinicians were not reported in any of the included studies.

ReviewInterprofessional collaboration: effects of practice-based interventions on professional practice and healthcare outcomes.
Poor interprofessional collaboration (IPC) can negatively affect the delivery of health services and patient care. Interventions that address IPC problems have the potential to improve professional practice and healthcare outcomes. ⋯ In this updated review, we found five studies (four new studies) that met the inclusion criteria. The review suggests that practice-based IPC interventions can improve healthcare processes and outcomes, but due to the limitations in terms of the small number of studies, sample sizes, problems with conceptualising and measuring collaboration, and heterogeneity of interventions and settings, it is difficult to draw generalisable inferences about the key elements of IPC and its effectiveness. More rigorous, cluster randomised studies with an explicit focus on IPC and its measurement, are needed to provide better evidence of the impact of practice-based IPC interventions on professional practice and healthcare outcomes. These studies should include qualitative methods to provide insight into how the interventions affect collaboration and how improved collaboration contributes to changes in outcomes.

Review Meta AnalysisRegular treatment with formoterol and inhaled steroids for chronic asthma: serious adverse events.
Epidemiological evidence has suggested a link between beta(2)-agonists and increases in asthma mortality. There has been much debate about possible causal links for this association, and whether regular (daily) long-acting beta(2)-agonists are safe when used alone or in conjunction with inhaled corticosteroids. ⋯ It is not possible, from the data in this review, to reassure people with asthma that inhaled corticosteroids with regular formoterol carries no risk of increasing mortality in comparison to inhaled corticosteroids alone as all four deaths occurred among 6,594 people using inhaled corticosteroids with formoterol. On the other hand, we have found no conclusive evidence of harm and there was only one asthma related death registered during over 3,000 patient year observation on formoterol. In adults, the decrease in asthma-related serious adverse events on regular formoterol with inhaled corticosteroids was not accompanied by a decrease in all cause serious adverse events. In children the number of events was too small, and consequently the results too imprecise, to determine whether the increase in all cause non-fatal serious adverse events found in the previous meta-analysis on regular formoterol alone is abolished by the additional use of inhaled corticosteroids. Clinical decisions and information for patients regarding regular use of formoterol have to take into account the balance between known symptomatic benefits of formoterol and the degree of uncertainty and concern associated with its potential harmful effects.

Review Meta AnalysisOxygen therapy for lower respiratory tract infections in children between 3 months and 15 years of age.
Usual practice in lower respiratory tract infections (LRTIs) includes administering complementary oxygen. The effectiveness of oxygen therapy and different methods of delivery is unknown. This review contributes to the rational use of oxygen in the treatment of LRTIs. ⋯ NP and NPC seem to be similar in effectiveness and safety when used in patients with LRTI. There is no single clinical sign or symptom that accurately identifies hypoxaemia. Studies identifying the most effective and safe oxygen delivery method are needed.
