ReviewIndividual participant data meta-analyses compared with meta-analyses based on aggregate data.
Meta-analyses based on individual participant data (IPD-MAs) allow more powerful and uniformly consistent analyses as well as better characterisation of subgroups and outcomes, compared to those which are based on aggregate data (AD-MAs) extracted from published trial reports. However, IPD-MAs are a larger undertaking requiring greater resources than AD-MAs. Researchers have compared results from IPD-MA against results obtained from AD-MA and reported conflicting findings. We present a methodology review to summarise this empirical evidence . ⋯ IPD offers the potential to explore additional, more thorough, and potentially more appropriate analyses compared to those possible with AD. But in many cases, similar results and conclusions can be drawn from IPD-MA and AD-MA. Therefore, before embarking on a resource-intensive IPD-MA, an AD-MA should initially be explored and researchers should carefully consider the potential added benefits of IPD.

The aim of the study was to evaluate and study the full spectrum of swallowing dysfunction and long-term disease-specific outcomes in adults with surgically corrected esophageal atresia/tracheaesophageal fistula (EA/TEF). ⋯ Swallowing dysfunction is common in adults who underwent EA/TEF repair as infants; however, patients reported minimal effect on QOL or day-to-day activities. The SDQ is a valid and reliable tool to measure the full spectrum of swallowing dysfunction in the EA/TEF repair population.

To assess current nationwide case selection factors for minimally invasive distal pancreatectomy (MIDP) and identify actual risk factors for adverse outcomes compared with open distal pancreatectomy (ODP). ⋯ Current selection factors for ODP or MIDP (benign disease, tumor size, and BMI) do not mitigate the risk of major morbidity. We found no evidence that MIDP should be avoided based on tumor etiology or size, BMI, or patient physical status.

Aortic valve stenosis is the most common type of valvular heart disease in the USA and Europe. Aortic valve stenosis is considered similar to atherosclerotic disease. Some studies have evaluated statins for aortic valve stenosis. ⋯ Result findings showed uncertainty surrounding the effect of statins for aortic valve stenosis.The quality of evidence from the reported outcomes ranged from moderate to very low. These results give support to European and USA guidelines (2012 and 2014, respectively) that so far there is no clinical treatment option for aortic valve stenosis.

ReviewTopiramate for acute affective episodes in bipolar disorder in adults.
Bipolar disorder is a common recurrent illness with high levels of chronicity. Previous trials have suggested that the anticonvulsant topiramate may be efficacious in bipolar disorder. This is an update of a previous Cochrane review (last published 2006) on the role of topiramate in bipolar disorder. ⋯ It is not possible to draw any firm conclusions about the use of topiramate in clinical practice from this evidence. The only high-quality evidence found was that lithium is more efficacious than topiramate when used as monotherapy in the treatment of acute affective episodes in bipolar disorder, and we note that this evidence came from only two studies. Moderate-quality evidence showed that topiramate was no more or less efficacious than placebo as monotherapy when a 3-week endpoint was used, but the quality of the evidence for this outcome at a 12-week endpoint dropped to low. As we graded the quality of the evidence for the other findings as low and very low, it was not possible to draw any conclusions from the results.To best address this research question, if investigators see the indication in so doing, more double-blind randomised controlled trials could be conducted that are more explicit with regard to methodological issues. In particular, investigators could compare placebo, alternative, and combination treatments (including a wide range of mood stabilisers), atypical antipsychotics for manic and mixed episodes, and antidepressants in combination with mood stabilisers or atypical antipsychotics for depressive episodes.
