Review Meta AnalysisShort-term treatment with proton pump inhibitors, H2-receptor antagonists and prokinetics for gastro-oesophageal reflux disease-like symptoms and endoscopy negative reflux disease.
Heartburn affects 25% of the adult population on a monthly basis and represents the core symptom of gastro-oesophageal reflux disease (GORD). Treatment is readily available and puts a large demand on healthcare budgets. A majority of GORD patients show no endoscopic abnormalities and in daily practice most patients are treated empirically. ⋯ The findings in this review suggest that antisecretory drugs are effective in the empirical treatment of complaints likely to originate from GORD and in treatment of ENRD and furthermore that PPIs are superior to H2RAs in empirical treatment of typical GORD symptoms.

Low-back pain is a costly illness for which spinal manipulative therapy is commonly recommended. Previous systematic reviews and practice guidelines have reached discordant results on the effectiveness of this therapy for low-back pain. ⋯ There is no evidence that spinal manipulative therapy is superior to other standard treatments for patients with acute or chronic low-back pain.

Review Meta AnalysisPre-operative education for hip or knee replacement.
Hip or knee replacement is a major surgical procedure which can be physically and psychologically stressful for patients. It is hypothesised that education before surgery reduces anxiety and enhances postoperative outcomes. ⋯ There is little evidence to support the use of pre-operative education over and above standard care to improve postoperative outcomes in patients undergoing hip or knee replacement surgery, especially with respect to pain, functioning and length of hospital stay. There is evidence that preoperative education has a modest beneficial effect on preoperative anxiety. There may also be beneficial effects when preoperative education is tailored according to anxiety, or targeted at those most in need of support (e.g. those who are particularly disabled, or have limited social support structures).

Agitation affects up to 70% of older people with dementia. Valproic acid has been used for the past 10 years to control agitation in dementia, but no systematic review of the effectiveness of this drug has been published to date. The current study examines three randomized, placebo-controlled trials of the effect of valproic acid on older people with dementia who were agitated. ⋯ The trials reviewed should be regarded as preliminary. Individual reports suggest that low dose sodium valproate is ineffective in treating agitation among demented patients, and that high dose divalproex sodium is associated with an unacceptable rate of adverse effects. More research on the use of valproate preparations for agitation of people with dementia is needed. On the basis of current evidence, valproate preparations cannot be recommended for the treatment of agitation in dementia.

Review Meta AnalysisHyperbaric oxygen therapy for the adjunctive treatment of traumatic brain injury.
Traumatic brain injury is common and presents a health problem with significant effect on quality of life. Hyperbaric oxygen therapy (HBOT) has been suggested to improve oxygen supply to the injured brain and, therefore, to reduce the volume of brain that will ultimately perish. It is postulated that the addition of HBOT to the standard intensive care regimen may result in a reduction in patient death and disability as a result of these additional brain-preserving effects. ⋯ In people with traumatic brain injury, the addition of HBOT significantly reduced the risk of death but not of favourable clinical outcome. The routine application of HBOT to these patients cannot be justified from this review. In view of the modest number of patients, methodological shortcomings and poor reporting, this result should be interpreted cautiously, and an appropriately powered trial of high methodological rigour is justified to define those patients (if any) who can be expected to derive most benefit from HBOT.
