Review Meta AnalysisMicronutrient supplementation for children with HIV infection.
Micronutrient deficiencies are widespread and compound the effects of HIV disease in children, especially in poor communities. Micronutrient supplements may be effective and safe in reducing the burden of HIV disease. This review is an update of an earlier Cochrane review of micronutrient supplementation in children and adults which found that vitamin A and zinc are beneficial and safe in children exposed to HIV and living with HIV infection (Irlam 2010). ⋯ Vitamin A supplementation is beneficial and safe in children with HIV infection. Zinc is safe and appears to have similar benefits on diarrhoeal morbidity in children with HIV as in children without HIV infection. Multiple micronutrient supplements have some clinical benefit in poorly nourished children with HIV infection.Further trials of single supplements (vitamin D, zinc, and selenium) are required to build the evidence base. The long-term effects and optimal composition and dosing of multiple micronutrient supplements require further investigation in children with diverse HIV disease status.

ReviewOptimal time for initiating antiretroviral therapy (ART) in HIV-infected, treatment-naive children aged 2 to 5 years old.
The use of combination antiretroviral therapy (cART) comprising three antiretroviral medications from at least two classes of drugs is the current standard treatment for HIV infection in adults and children. Current World Health Organization (WHO) guidelines for antiretroviral therapy recommend early treatment regardless of immunologic thresholds or the clinical condition for all infants (less than one years of age) and children under the age of two years. For children aged two to five years current WHO guidelines recommend (based on low quality evidence) that clinical and immunological thresholds be used to identify those who need to start cART (advanced clinical stage or CD4 counts ≤ 750 cells/mm(3) or per cent CD4 ≤ 25%). This Cochrane review will inform the current available evidence regarding the optimal time for treatment initiation in children aged two to five years with the goal of informing the revision of WHO 2013 recommendations on when to initiate cART in children. ⋯ This systematic review shows that there is insufficient evidence from clinical trials in support of either early or CD4-guided initiation of ART in HIV-infected children aged 2 to 5 years. Programmatic issues such as the retention in care of children in ART programmes in resource-limited settings will need to be considered when formulating WHO 2013 recommendations.

Review Meta AnalysisManual small incision cataract surgery (MSICS) with posterior chamber intraocular lens versus phacoemulsification with posterior chamber intraocular lens for age-related cataract.
Age-related cataract is a major cause of blindness and visual morbidity worldwide. It is therefore important to establish the optimal technique of lens removal in cataract surgery. ⋯ On the basis of this review, removing cataract by phacoemulsification may result in better UCVA in the short term (up to three months after surgery) compared to MSICS, but similar BCVA. There is a lack of data on long-term visual outcome. The review is currently underpowered to detect differences for rarer outcomes, including poor visual outcome. In view of the lower cost of MSICS, this may be a favourable technique in the patient populations examined in these studies, where high volume surgery is a priority. Further studies are required with longer-term follow-up to better assess visual outcomes and complications which may develop over time such as posterior capsule opacification.

Croup is a common childhood illness characterized by barky cough, stridor, hoarseness and respiratory distress. Children with severe croup are at risk for intubation. Nebulized epinephrine may prevent intubation. ⋯ Nebulized epinephrine is associated with clinically and statistically significant transient reduction of symptoms of croup 30 minutes post-treatment. Evidence does not favor racemic epinephrine or L-epinephrine, or IPPB over simple nebulization.The authors note that data and analyses were limited by the small number of relevant studies and total number of participants and thus most outcomes contained data from very few or even single studies.

Review Meta AnalysisIntegrated disease management interventions for patients with chronic obstructive pulmonary disease.
In people with chronic obstructive pulmonary disease (COPD) there is considerable variation in symptoms, limitations and well-being, which often complicates medical care. To improve quality of life (QoL) and exercise tolerance, while reducing the number of exacerbations, a multidisciplinary program including different elements of care is needed. ⋯ In these COPD participants, IDM not only improved disease-specific QoL and exercise capacity, but also reduced hospital admissions and hospital days per person.
