Occupational therapy delivered by specialists versus non-specialists for people with schizophrenia.
Schizophrenia is a severe mental health condition that is characterised by positive symptoms, such as hallucinations and delusions; negative symptoms, such as flattened affect, thought disorder (disrupted speech), and lack of motivation; and cognitive symptoms, such as problems with memory and attention. Schizophrenia can occur as an isolated episode, or as a recurring cycle of remission and relapse, and is associated with impairment in psychosocial and occupational functioning.Although antipsychotic drugs are the main treatment for people with schizophrenia, in most countries mental health services usually provide a range of add-on interventions, including occupational therapy. This is a complex intervention designed to support and enable continued participation in daily life through engagement in activities and occupations meaningful to the individual. Occupational therapists are professionals trained to deliver therapy where the emphasis is on improving occupational function and participation rather than treating symptoms, and uses a wide range of methods based on the needs of individuals. However, similar interventions may also be delivered by staff not trained as occupational therapists. ⋯ Currently there are no randomised controlled trials comparing delivery of occupational therapy for people diagnosed with schizophrenia by occupational therapists with delivery of similar interventions by anyone other than occupational therapists. Research studies employing methodologically robust trial designs are needed to establish whether or not there are better outcomes for people with a diagnosis of schizophrenia with occupational therapy that is delivered by trained occupational therapists.

Post-thrombotic syndrome (PTS) is a long-term complication of deep venous thrombosis (DVT) that is characterised by pain, swelling, and skin changes in the affected limb. One in three patients with DVT will develop post-thrombotic sequelae within five years. The current standard care for the prevention of PTS following DVT is elastic compression stockings. Rutosides are a group of compounds derived from horse chestnut (Aesculus hippocastanum), a traditional herbal remedy for treating oedema formation in chronic venous insufficiency (CVI). However, it is not known whether rutosides are effective and safe in the prevention of PTS. This is the second update of the review first published in 2013. ⋯ As there were no studies identified in this review there is currently insufficient evidence to determine the effectiveness and safety of rutosides for prevention of PTS in patients with DVT. Some studies suggest that rutosides may provide short-term relief of PTS symptoms. However, there is nothing published on their use as a preventative therapy for PTS. High quality randomised controlled trials of rutoside versus any alternative are required to build the evidence base in this area.

WITHDRAWN: Iodine supplementation for preventing iodine deficiency disorders in children.
Iodine deficiency is the main cause of potentially preventable mental retardation in childhood, as well as causing goitre and hypothyroidism in people of all ages. It is still prevalent in large parts of the world. ⋯ Despite most of the included studies being of low quality, the results suggest that iodine supplementation, especially iodised oil, is an effective means of decreasing goitre rates and improving iodine status in children. Indications of positive effects on physical and mental development and mortality were seen, although results were not always significant. Adverse effects were generally minor and transient. Insufficient evidence was available on non-oil supplements. High quality controlled studies investigating relevant long term outcome measures are needed to address the question of the best form of iodine supplementation in different population groups and settings.

Sickle cell disease encompasses a group of genetic disorders characterized by the presence of at least one hemoglobin S (Hb S) allele, and a second abnormal allele that could allow abnormal hemoglobin polymerisation leading to a symptomatic disorder.Autosomal recessive disorders (such as sickle cell disease) are good candidates for gene therapy because a normal phenotype can be restored in diseased cells with only a single normal copy of the mutant gene. This is an update of a previously published Cochrane Review. ⋯ No randomised or quasi-randomised clinical trials of gene therapy for sickle cell disease were reported. Thus, no objective conclusions or recommendations in practice can be made on gene therapy for sickle cell disease. This systematic review has identified the need for well-designed, randomised controlled trials to assess the benefits and risks of gene therapy for sickle cell disease.

Energy (calorie) labelling for healthier selection and consumption of food or alcohol.
This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To estimate the effect of energy labelling for food (including non‐alcoholic drinks) and alcoholic drinks on healthier selection (with or without purchasing) and consumption. To assess possible modifiers – energy label type, setting and socioeconomic status ‐ of the effect of energy labelling on selection and consumption of food and alcohol.
