Review Comparative Study
Antiplatelet therapy in patients with ST-elevation myocardial infarction undergoing myocardial revascularisation: beyond clopidogrel.
Despite revascularisation, outcomes among patients presenting with ST-elevation myocardial infarction (STEMI) remain suboptimal. ⋯ Future studies also need to address several other outstanding issues, such as the subsequent approach if patients do not undergo PCI, and to overcome limitations in and differences between the primary studies. In particular, head-to-head comparisons need to compare directly the risks and benefits of ticagrelor and prasugrel in STEMI patients. These caveats notwithstanding, ticagrelor and prasugrel markedly improve the prognosis for patients with STEMI.

Despite limited empirical support, chronic pain has traditionally been defined mainly on the basis of its duration, which takes no account of the causative mechanisms or its clinical significance. ⋯ The implementation of a prognostic definition and wider adoption of integrated care could bring significant advantages. However, these measures require improved training in pain management and structural revision of specialist facilities, for which political support is essential.

Intravenous iron sucrose has been used to treat iron deficiency and iron deficiency anaemia associated with different chronic diseases for several decades. Despite the complex structure of iron sucrose, copies called iron sucrose similars (ISSs) have been approved according to the generic approach and therefore, therapeutic equivalence is taken for granted. ⋯ Due to emerging evidence that ISSs differ from the iron sucrose originator in safety and efficacy profiles, it seems prudent for physicians as well as patients who require intravenous (i.v.) iron to have available data on therapeutic equivalence of new ISS preparations versus the originator. This may be especially important in patients who are chronically ill and need iron supplementation on a regular, long-term basis.

Review Comparative Study
Clinical effectiveness of inhaled corticosteroids versus montelukast in children with asthma: prescription patterns and patient adherence as key factors.
To examine the real-life effectiveness of inhaled corticosteroids (ICS) versus leukotriene receptor antagonists (LTRA) monotherapy in children with mild or moderate asthma. ⋯ When compared to LTRA, the prescription of ICS monotherapy did not significantly reduce rescue oral corticosteroids or acute care visits and was associated with a higher rate of hospital admission for asthma and rescue β(2)-agonist use. The findings may be due to paradoxical shorter ICS prescription duration and lower patient adherence, despite more persistent asthma and poorer control than in LTRA-treated children.

The quality of the clinical data supporting the development and ultimately the approval for medical use of new drugs is often challenged. Many share the perception that the business goals of the pharmaceutical industry overrule the best scientific efforts to accrue critical knowledge on a new molecule, in order to inform investment of resources, regulatory approvals and appropriate use by patients. Despite this common belief, few scientists have attempted to assess objectively the quality of industry funded (IF) clinical trials by measuring it and comparing it with non-industry funded (NIF) clinical trials in a data-driven fashion. Overall, the average quality of IF clinical research has been reported to be higher than the quality of NIF clinical research.
