ReviewExtracorporeal membrane oxygenation for critically ill adults.
Extracorporeal membrane oxygenation (ECMO) may provide benefit in certain populations of adults, including those with severe cardiac failure, severe respiratory failure, and cardiac arrest. However, it is also associated with serious short- and long-term complications, and there remains a lack of high-quality evidence to guide practice. Recently several large randomized controlled trials (RCTs) have been published, therefore, we undertook an update of our previous systematic review published in 2014. ⋯ In this updated systematic review, which included four additional RCTs, we found that ECMO was associated with a reduction in day-90 to one-year all-cause mortality, as well as three times increased risk of bleeding. However, the certainty of this result was only low to moderate, limited by a low number of small trials, clinical heterogeneity, and indirectness across studies.

ReviewAutoinflation for otitis media with effusion (OME) in children.
Otitis media with effusion (OME) is an accumulation of fluid in the middle ear cavity, common amongst young children. The fluid may cause hearing loss. When persistent, it may lead to behavioural problems and a delay in expressive language skills. Management of OME includes watchful waiting, medical, surgical and mechanical treatment. Autoinflation is a self-administered technique, which aims to ventilate the middle ear and encourage middle ear fluid clearance by providing a positive pressure of air in the nose and nasopharynx (using a nasal balloon or other handheld device). This positive pressure (sometimes combined with simultaneous swallow) encourages opening of the Eustachian tube and may help ventilate the middle ear. ⋯ All the evidence we identified was of low or very low certainty, meaning that we have little confidence in the estimated effects. However, the data suggest that autoinflation may have a beneficial effect on OME-specific quality of life and persistence of OME in the short term, but the effect is uncertain for return to normal hearing and adverse effects. The potential benefits should be weighed against the inconvenience of regularly carrying out autoinflation, and the possible risk of ear pain.

ReviewSilicone hydrogel versus hydrogel soft contact lenses for differences in patient-reported eye comfort and safety.
Ocular discomfort is the leading cause of permanent discontinuation of soft contact lens (SCL) wear. Silicone hydrogel and hydrogel materials are the two major categories of SCLs, with silicone hydrogel materials being newer and more breathable than hydrogel materials. Whether comfort is associated with SCL material is controversial despite numerous studies. Similarly, the difference between these materials in terms of safety outcomes (e.g. frequency of microbial keratitis) is unclear. ⋯ The overall evidence for a difference between all included silicone hydrogel and hydrogel SCLs was of very low certainty, with most trials at high overall risk of bias. The majority of studies did not assess comfort using a validated instrument. There was insufficient evidence to support recommending one SCL material over the other. For extended wear, hydrogel SCL may have a lower risk of adverse events at 52 weeks compared to silicon hydrogel. Future well-designed trials are needed to generate high certainty evidence to further clarify differences in SCL material comfort and safety.
