Colesevelam is a second-generation bile acid sequestrant that has effects on both blood glucose and lipid levels. It provides a promising approach to glycaemic and lipid control simultaneously. ⋯ Colesevelam added on to antidiabetic agents showed significant effects on glycaemic control. However, there is a limited number of studies with the different colesevelam/antidiabetic agent combinations. More information on the benefit-risk ratio of colesevelam treatment is necessary to assess the long-term effects, particularly in the management of cardiovascular risks as well as the reduction in micro- and macrovascular complications of type 2 diabetes mellitus. Furthermore, long-term data on health-related quality of life and all-cause mortality also need to be investigated.

ReviewNebulised surfactant in preterm infants with or at risk of respiratory distress syndrome.
Nebulised surfactant has the potential to deliver surfactant to the infant lung with the goal of avoiding endotracheal intubation and ventilation, ventilator-induced lung injury and bronchopulmonary dysplasia (BPD). ⋯ There are insufficient data to support or refute the use of nebulised surfactant in clinical practice. Adequately powered trials are required to determine the effect of nebulised surfactant administration for prevention or early treatment of RDS in preterm infants. Nebulised surfactant administration should be limited to clinical trials.

Paliperidone palmitate, a long-acting, intramuscular formulation of paliperidone, is now available for clinical use. Paliperidone is an active metabolite of risperidone and it is also available in an oral formulation for daily use. ⋯ In short-term studies, paliperidone palmitate is an antipsychotic drug that is more efficacious than placebo. We found its adverse effects to be similar to those of its related compounds, paliperidone and risperidone, with extrapyramidal movement disorders, weight gain, and tachycardia all more common with paliperidone palmitate than placebo. While no difference was found in the incidence of reported adverse sexual outcomes, paliperidone palmitate is associated with substantial increases in serum prolactin. When flexibly dosed with a mean doses of approximately 70 to 110 mg every four weeks, paliperidone palmitate appears comparable in efficacy and tolerability to risperidone long-acting injection flexibly dosed with mean doses of approximately 35 mg every two weeks.

Review Meta AnalysisExternal counterpulsation for acute ischaemic stroke.
External counterpulsation (ECP) may improve cerebral blood flow, and it has been proposed as a potential therapy for patients with ischaemic stroke. ⋯ The methodological quality of the included studies was poor, and reliable conclusions could not be drawn from the present data. High-quality and large-scale RCTs are needed.

Review Meta AnalysisVigabatrin versus carbamazepine monotherapy for epilepsy.
The efficacy and safety of vigabatrin (VGB) as an add-on therapy for refractory epilepsy has been well established. However, this needs to be weighed against the risk of the development of visual field defects. Whether VGB monotherapy is an effective and safe treatment compared with the standard antiepileptic drug carbamazepine (CBZ) monotherapy for epilepsy has not been systematically reviewed. ⋯ There is currently insufficient data to address the risk-benefit balance of using VGB versus CBZ monotherapy for epilepsy. Considering the high prevalence of visual field defects, reported in an existing systematic review of observational studies (Maguire 2010), the prescribing of VGB monotherapy for epilepsy should be used with caution and not considered as a first-line choice. If necessary, a frequent assessment of visual field is needed. Future research should focus on investigating the reasons for visual field defects and exploring the potential prevention strategies. Moreover, future monotherapy studies of epilepsy should report results according to the recommendation of International League Against Epilepsy (ILAE) Commission, and methodological quality should be improved.
