ReviewEducation support services for improving school engagement and academic performance of children and adolescents with a chronic health condition.
Chronic health conditions in children and adolescents can have profound impacts on education, well-being and health. They are described as non-communicable illnesses that are prolonged in duration, do not resolve spontaneously, and rarely cured completely. Due to variations in the definition of chronic health conditions and how they are measured prevalence estimates vary considerably and have been reported to be as high as 44% in children and adolescents. Of young people with a chronic health condition, an estimated 5% are affected by severe conditions characterised by limitations to daily activities impacting their ability to attend school. School attendance is important for academic and social skill development as well as well-being. When children and adolescents are absent from school due to a chronic health condition, school engagement can be affected. Disengagement from school is associated with poorer academic achievement, social-emotional functioning and career choices. Education support services for children and adolescents with chronic health conditions aim to prevent disengagement from school, education and learning during periods where their illness caused them to miss school. However, there is limited evidence on the effectiveness of educational support interventions at improving school engagement and educational/learning outcomes for children and adolescents with chronic health conditions. ⋯ This review has demonstrated the infancy of quality research on the effectiveness of education support interventions for children and adolescents with chronic health conditions. At best, we can say that we are uncertain whether education support interventions improve either academic achievement or school engagement. Of the secondary outcomes, we are also uncertain whether education support interventions improve transition back to school, or school re-entry. However, we suggest there is some evidence that education support may slightly improve mental health, measured as self-esteem. Given the current state of the evidence of the effectiveness of education support interventions for children and adolescents with chronic health conditions, we highlight some important implications for future research in this field to strengthen the evidence that can inform effective practice and policy.

ReviewPreoperative combined mechanical and oral antibiotic bowel preparation for preventing complications in elective colorectal surgery.
The success of elective colorectal surgery is mainly influenced by the surgical procedure and postoperative complications. The most serious complications include anastomotic leakages and surgical site infections (SSI)s, which can lead to prolonged recovery with impaired long-term health. Compared with other abdominal procedures, colorectal resections have an increased risk of adverse events due to the physiological bacterial colonisation of the large bowel. Preoperative bowel preparation is used to remove faeces from the bowel lumen and reduce bacterial colonisation. This bowel preparation can be performed mechanically and/or with oral antibiotics. While mechanical bowel preparation alone is not beneficial, the benefits and harms of combined mechanical and oral antibiotic bowel preparation is still unclear. ⋯ Based on moderate-certainty evidence, our results suggest that MBP+oAB is probably more effective than MBP alone in preventing postoperative complications. In particular, with respect to our primary outcomes, SSI and anastomotic leakage, a lower incidence was demonstrated using MBP+oAB. Whether oAB alone is actually equivalent to MBP+oAB, or leads to a reduction or increase in the risk of postoperative complications, cannot be clarified in light of the low- to very low-certainty evidence. Similarly, it remains unclear whether omitting preoperative bowel preparation leads to an increase in the risk of postoperative complications due to limited evidence. Additional RCTs, particularly on the comparisons of MBP+oAB versus oAB alone or nBP, are needed to assess the impact of oAB alone or nBP compared with MBP+oAB on postoperative complications and to improve confidence in the estimated effect. In addition, RCTs focusing on subgroups (e.g. in relation to type and location of colon resections) or reporting side effects of the intervention are needed to determine the most effective approach of preoperative bowel preparation.

Since the previous Cochrane Review on this topic in 2016, debate has continued surrounding a potential role for vitamin D in reducing risk of asthma exacerbation and improving asthma control. We therefore conducted an updated meta-analysis to include data from new trials completed since this date. ⋯ In contrast to findings of our previous Cochrane Review on this topic, this updated review does not find evidence to support a role for vitamin D supplementation or its hydroxylated metabolites to reduce risk of asthma exacerbations or improve asthma control. Participants with severe asthma and those with baseline 25(OH)D concentrations < 25 nmol/L were poorly represented, so further research is warranted here. A single study investigating effects of calcidiol yielded positive results, so further studies investigating effects of this metabolite are needed.

ReviewBehavioural and cognitive-behavioural interventions for outwardly directed aggressive behaviour in people with intellectual disabilities.
Outwardly directed aggressive behaviour in people with intellectual disabilities is a significant issue that may lead to poor quality of life, social exclusion and inpatient psychiatric admissions. Cognitive and behavioural approaches have been developed to manage aggressive behaviour but the effectiveness of these interventions on reducing aggressive behaviour and other outcomes are unclear. This is the third update of this review and adds nine new studies, resulting in a total of 15 studies in this review. ⋯ There is moderate-certainty evidence that cognitive-behavioural approaches such as anger management and PBS may reduce outwardly directed aggressive behaviour in the short term but there is less certainty about the evidence in the medium and long term, particularly in relation to other outcomes such as quality of life. There is some evidence to suggest that combining more than one intervention may have cumulative benefits. Most studies were small and there is a need for larger, robust randomised controlled trials, particularly for interventions where the certainty of evidence is very low. More trials are needed that focus on children and whether psychological interventions lead to reductions in the use of psychotropic medications.

ReviewEndovascular therapy versus medical treatment for symptomatic intracranial artery stenosis.
Intracranial artery stenosis (ICAS) is an arterial narrowing in the brain that can cause stroke. Endovascular therapy (ET) and conventional medical treatment (CMT) may prevent recurrent ischaemic stroke caused by ICAS. However, there is no consensus on the best treatment for people with ICAS. ⋯ This review provides moderate-certainty evidence that ET plus CMT compared with CMT alone increases the risk of short-term stroke and death in people with recent symptomatic severe ICAS. This effect was still apparent at long-term follow-up but appeared to be due to the early risks of ET; therefore, there may be no clear difference between the interventions in terms of their effects on long-term stroke and death. The impact of delayed ET intervention (more than three weeks after a qualifying event) warrants further study.
