Psoriasis is a chronic inflammatory skin condition that can markedly reduce life quality. Several systemic therapies exist for moderate to severe psoriasis, including oral fumaric acid esters (FAE). These contain dimethyl fumarate (DMF), the main active ingredient, and monoethyl fumarate. FAE are licensed for psoriasis in Germany but used off-licence in many countries. ⋯ Evidence suggests that FAE are superior to placebo and possibly similar in efficacy to MTX for psoriasis; however, the evidence provided in this review was limited, and it must be noted that four out of six included studies were abstracts or brief reports, restricting study reporting. FAE are associated with nuisance adverse effects, including flushing and gastrointestinal disturbance, but short-term studies reported no serious adverse effects.

Review Meta AnalysisEarly versus late removal of the laryngeal mask airway (LMA) for general anaesthesia.
The laryngeal mask airway (LMA) is a safe and effective modality to maintain the airway for general anaesthesia during surgical procedures. The LMA is removed at the end of surgery and anaesthesia, when the patient maintains an adequate respiratory rate and depth. This removal of the LMA can be done either when the patient is deep under anaesthesia (early removal) or only after the patient has regained consciousness (late removal). It is not clear which of these techniques is superior. ⋯ This systematic review suggests that current best evidence comparing early versus late removal of the LMA in participants undergoing general anaesthesia does not demonstrate superiority of either intervention. However, the quality of evidence available is either low or very low. There is a paucity of well designed RCTs and a need for large scale RCTs to demonstrate whether early removal or late removal of the LMA is better after general anaesthesia.

Review Meta AnalysisAlpha-2 adrenergic agonists for the prevention of shivering following general anaesthesia.
Shivering after general anaesthesia is common. It is unpleasant but can also have adverse physiological effects. Alpha-2 (α-2) adrenergic agonist receptors, which can lead to reduced sympathetic activity and central regulation of vasoconstrictor tone, are a group of drugs that have been used to try to prevent postoperative shivering. ⋯ There is evidence that clonidine and dexmedetomidine can reduce postoperative shivering, but patients given dexmedetomidine may be more sedated. However, our assessment of the quality of this evidence is very low.

Review Meta AnalysisInterventions for preventing and treating kidney disease in Henoch-Schönlein Purpura (HSP).
Henoch-Schönlein purpura (HSP) is the most common vasculitis of childhood but may occur in adults. This small vessel vasculitis is characterised by palpable purpura, abdominal pain, arthritis or arthralgia and kidney involvement. This is an update of a review first published in 2009. ⋯ There are no substantial changes in conclusions from this update compared with the initial review. From generally low quality evidence, we found no evidence of benefit from RCTs for the use of prednisone or antiplatelet agents to prevent persistent kidney disease in children with HSP. Though heparin appeared effective, this potentially dangerous therapy is not justified to prevent serious kidney disease when fewer than 2% of children with HSP develop severe kidney disease. No evidence of benefit has been found for cyclophosphamide treatment in children or adults with HSP and severe kidney disease. Because of small patient numbers and events leading to imprecision in results, it remains unclear whether cyclosporin and mycophenolate mofetil have any roles in the treatment of children with HSP and severe kidney disease.

In order to prevent overweight and obesity in the general population we need to understand the relationship between the proportion of energy from fat and resulting weight and body fatness in the general population. ⋯ Trials where participants were randomised to a lower fat intake versus usual or moderate fat intake, but with no intention to reduce weight, showed a consistent, stable but small effect of low fat intake on body fatness: slightly lower weight, BMI and waist circumference compared with controls. Greater fat reduction and lower baseline fat intake were both associated with greater reductions in weight. This effect of reducing total fat was not consistently reflected in cohort studies assessing the relationship between total fat intake and later measures of body fatness or change in body fatness in studies of children, young people or adults.
