Review Meta AnalysisEnteral iron supplementation in preterm and low birth weight infants.
Preterm infants are at risk of exhausting their body iron stores much earlier than healthy term newborns. It is widespread practice to give enteral iron supplementation to preterm and low birth weight infants to prevent iron deficiency anaemia. However, it is unclear whether supplementing preterm and low birth weight infants with iron improves growth and neurodevelopment. It is suspected that excess exogenous iron can contribute to oxidative injury in preterm babies, causing or exacerbating conditions such as necrotising enterocolitis and retinopathy of prematurity. Additionally, the optimal dose and timing of commencement and cessation of iron supplementation are uncertain. ⋯ The available data suggest that infants who receive iron supplementation have a slightly higher haemoglobin level, improved iron stores and a lower risk of developing iron deficiency anaemia when compared with those who are unsupplemented. However, it is unclear whether iron supplementation in preterm and low birth weight infants has long term benefits in terms of neurodevelopmental outcome and growth. The optimum timing and duration of iron supplementation remains unclear.

Review Meta AnalysisHypnosis for pain management during labour and childbirth.
This review is one in a series of Cochrane Reviews investigating pain management for childbirth. These reviews all contribute to an overview of systematic reviews of pain management for women in labour, and share a generic protocol. We examined the current evidence regarding the use of hypnosis for pain management during labour and childbirth. This review updates the findings regarding hypnosis from an earlier review of complementary and alternative therapies for pain management in labour into a stand-alone review. ⋯ There are still only a small number of studies assessing the use of hypnosis for labour and childbirth. Although the intervention shows some promise, further research is needed before recommendations can be made regarding its clinical usefulness for pain management in maternity care.

Review Meta AnalysisActive cycle of breathing technique for cystic fibrosis.
People with cystic fibrosis experience chronic airway infections as a result of mucus build up within the lungs. Repeated infections often cause lung damage and disease. Airway clearance therapies aim to improve mucus clearance, increase sputum production, and improve airway function. The active cycle of breathing technique (ACBT) is an airway clearance method that uses a cycle of techniques to loosen airway secretions including breathing control, thoracic expansion exercises, and the forced expiration technique. ⋯ There is insufficient evidence to support or reject the use of ACBT over any other airway clearance therapy. Five studies, with five different comparators, found that ACBT was comparable to other therapies in outcomes such as patient preference, lung function, sputum weight, oxygen saturation, and number of pulmonary exacerbations. Longer-term studies are needed to more adequately assess the effects of ACBT on outcomes important for patients such as quality of life and patient preference.

The common cold is a frequent illness, which, although benign and self-limiting, results in many consultations to primary care and considerable loss of school or work days. Current symptomatic treatments have limited benefit. Corticosteroids are an effective treatment in other upper respiratory tract infections and their anti-inflammatory effects may also be beneficial in the common cold. ⋯ Current evidence does not support the use of intranasal corticosteroids for symptomatic relief from the common cold. However, there were only two trials and limited statistical power. Further large randomised placebo-controlled trials in adults and children are required to answer this question.

Review Meta AnalysisCognitive stimulation to improve cognitive functioning in people with dementia.
Cognitive stimulation is an intervention for people with dementia which offers a range of enjoyable activities providing general stimulation for thinking, concentration and memory usually in a social setting, such as a small group. Its roots can be traced back to Reality Orientation (RO), which was developed in the late 1950s as a response to confusion and disorientation in older patients in hospital units in the USA. RO emphasised the engagement of nursing assistants in a hopeful, therapeutic process but became associated with a rigid, confrontational approach to people with dementia, leading to its use becoming less and less common.Cognitive stimulation is often discussed in normal ageing as well as in dementia. This reflects a general view that lack of cognitive activity hastens cognitive decline. With people with dementia, cognitive stimulation attempts to make use of the positive aspects of RO whilst ensuring that the stimulation is implemented in a sensitive, respectful and person-centred manner.There is often little consistency in the application and availability of psychological therapies in dementia services, so a systematic review of the available evidence regarding cognitive stimulation is important in order to identify its effectiveness and to place practice recommendations on a sound evidence base. ⋯ There was consistent evidence from multiple trials that cognitive stimulation programmes benefit cognition in people with mild to moderate dementia over and above any medication effects. However, the trials were of variable quality with small sample sizes and only limited details of the randomisation method were apparent in a number of the trials. Other outcomes need more exploration but improvements in self-reported quality of life and well-being were promising. Further research should look into the potential benefits of longer term cognitive stimulation programmes and their clinical significance.
