Obesity is one of the major public health problems of modern society. Intragastric balloon (IGB) treatment for obesity has been developed as a temporary aid. Its primary objective is the treatment of obese people, who have had unsatisfactory results in their clinical treatment for obesity, despite of being cared for by a multidisciplinary team, and super obese patients with a higher surgical risk. However, the effects of different IGB procedures compared with conventional treatments and with each other are uncertain. ⋯ Evidence from this review is limited for decision making, since there was large heterogeneity in IGB trials, regarding both methodological and clinical aspects. However, a co-adjuvant factor described by some authors in the loss and maintenance of weight has been the motivation and the encouragement to changing eating habits following a well-organized diet and a program of behavioural modification. The IGB alone and the technique of positioning appear to be safe. Despite the evidence for little additional benefit of the intragastric balloon in the loss of weight, its cost should be considered against a program of eating and behavioural modification.

Peripheral arterial disease (PAD) affects 4% to 12% of people aged 55 to 70 years and 20% of people over 70 years. The most common complaint is intermittent claudication (IC) characterised by pain in the legs or buttocks that occurs with exercise and which subsides with rest. Compared with age-matched controls, people with IC have a three- to six-fold increase in cardiovascular mortality. Symptoms of IC, walking distance, and quality of life can be improved by risk factor modification, smoking cessation, and a structured exercise program. Antiplatelet treatment is beneficial in patients with IC for the reduction of vascular events but has not been shown to influence claudication distance. ⋯ Patients with IC should receive secondary prevention for cardiovascular disease. Cilostazol has been shown to be of benefit in improving walking distance in people with IC. There are no data on whether it results in a reduction of adverse cardiovascular events.

Review Meta AnalysisCessation of medication for people with schizophrenia already stable on chlorpromazine.
Chlorpromazine, one of the first generation of antipsychotic drugs, is effective in the treatment of schizophrenia. For most people schizophrenia is a life-long disorder but about a quarter of those who have a first psychotic breakdown do not go on to experience further breakdowns. Most people with schizophrenia are prescribed antipsychotic drugs, although use is often intermittent. The effects of stopping medication are not well researched in the context of systematic reviews. ⋯ This review confirms clinical experience and quantifies the risks of stopping chlorpromazine medication for a group of people with schizophrenia who are stable on this drug. With its moderate adverse effects, chlorpromazine is likely to remain one of the most widely prescribed treatments for schizophrenia.

Multiple sclerosis is a presumed cell-mediated autoimmune disease of the central nervous system. Cyclophosphamide (CFX) is a cytotoxic and immunosuppressive agent, used in systemic autoimmune diseases. Controversial results have been reported on its efficacy in MS. We conducted a systematic review of all relevant trials, evaluating the efficacy of CFX in patients with progressive MS. ⋯ We were unable to achieve all of the objectives specified for the review. This review shows that the overall effect of CFX (administered as intensive schedule) in the treatment of progressive MS does not support its use in clinical practice.

Review Meta AnalysisOral fluphenazine versus placebo for schizophrenia.
Fluphenazine is one of the first drugs to be classed as an 'antipsychotic' and has been widely available for five decades. ⋯ The findings in this review confirm much that clinicians and recipients of care already know, but they provide quantification to support clinical impression. Fluphenazine's global position as an effective treatment for psychoses is not threatened by the outcome of this review. However, fluphenazine is an imperfect treatment and If accessible, other inexpensive drugs less associated with adverse effects may be an equally effective choice for people with schizophrenia.
