High-flow nasal cannulae for respiratory support in adult intensive care patients.

Background: High-flow nasal cannulae (HFNC) deliver high flows of blended humidified air and oxygen via wide-bore nasal cannulae and may be useful in providing respiratory support for adults experiencing acute respiratory failure, or at risk of acute respiratory failure, in the intensive care unit (ICU). This is an update of an earlier version of the review.

Objectives: To assess the effectiveness of HFNC compared to standard oxygen therapy, or non-invasive ventilation (NIV) or non-invasive positive pressure ventilation (NIPPV), for respiratory support in adults in the ICU.

From proband to provider: is there an obligation to inform genetic relatives of actionable risks discovered through direct-to-consumer genetic testing?

Direct-to-consumer genetic testing is a growing phenomenon, fuelled by the notion that knowledge equals control. One ethical question that arises concerns the proband's duty to share information indicating genetic risks in their relatives. However, such duties are unenforceable and may result in the realisation of anticipated harm to relatives.

Interventions to reduce body temperature to 35 ⁰C to 37 ⁰C in adults and children with traumatic brain injury.

Background: Traumatic brain injury (TBI) is a major cause of death and disability, with an estimated 5.5 million people experiencing severe TBI worldwide every year. Observational clinical studies of people with TBI suggest an association between raised body temperature and unfavourable outcome, although this relationship is inconsistent.

Long-term GnRH agonist therapy before in vitro fertilisation (IVF) for improving fertility outcomes in women with endometriosis.

Background: Endometriosis is known to have an impact on fertility and it is common for women affected by endometriosis to require fertility treatments, including in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI), to improve the chance of pregnancy. It has been postulated that long-term gonadotrophin-releasing hormone (GnRH) agonist therapy prior to IVF or ICSI can improve pregnancy outcomes. This systematic review supersedes the previous Cochrane Review on this topic (Sallam 2006).
