Review Meta AnalysisAlginate scaffolds improve functional recovery after spinal cord injury.
In this systematic review and meta-analysis, the use of alginate for the repair of the damaged spinal cord was investigated. ⋯ These findings suggest that alginate is an efficient scaffold for functional recovery and even a much better scaffold for drug/cell delivery after SCI.

Review Meta Analysis
Effect of the novel functional fibre, polyglycoplex (PGX), on body weight and metabolic parameters: A systematic review of randomized clinical trials.
Hundreds of dietary supplements are marketed as weight loss pills, but the evidence for effectiveness for most is unproven. The objective of this review was to critically appraise and evaluate the evidence from published randomized clinical trials (RCTs) examining the effectiveness of polyglycoplex (PGX), a novel functional fibre, on body weight and metabolic parameters. ⋯ The evidence from available RCTs does not indicate that PGX intake causes reductions in body weight. PGX may cause reductions in total and LDL cholesterol. Few trials examining the effects of PGX have been conducted; they are characterized by small sample sizes, deficiencies in reporting quality, and are funded by a single manufacturer. Future clinical trials evaluating its effect should be adequately powered and better reported.

Venous leg ulcers are a common and recurring type of chronic, complex wound associated with considerable cost to patients and healthcare providers. To aid healing, primary wound contact dressings are usually applied to ulcers beneath compression devices. Alginate dressings are used frequently and there is a variety of alginate products on the market, however, the evidence base to guide dressing choice is sparse. ⋯ The current evidence base does not suggest that alginate dressings are more or less effective in the healing of venous leg ulcers than hydrocolloid or plain non-adherent dressings, and there is no evidence to indicate a difference between different proprietary alginate dressings. However, the RCTs in this area are considered to be of low or unclear methodological quality. Further, good quality evidence is required from well designed and rigorously conducted RCTs that employ - and clearly report on - methods to minimise bias, prior to any definitive conclusions being made regarding the efficacy of alginate dressings in the management of venous leg ulcers.

Review Meta AnalysisAlginate dressings for treating pressure ulcers.
Pressure ulcers, also known as bedsores, decubitus ulcers and pressure injuries, are localised areas of injury to the skin or the underlying tissue, or both. Dressings are widely used to treat pressure ulcers and there are many options to choose from including alginate dressings. A clear and current overview of current evidence is required to facilitate decision-making regarding dressing use for the treatment of pressure ulcers. This review is part of a suite of Cochrane reviews investigating the use of dressings in the treatment of pressure ulcers. Each review will focus on a particular dressing type. ⋯ The relative effects of alginate dressings compared with alternative treatments are unclear. The existing trials are small, of short duration and at risk of bias. Decision makers may wish to consider aspects such as cost of dressings and the wound management properties offered by each dressing type, for example, exudate management.

Review Meta AnalysisAlginate dressings for healing diabetic foot ulcers.
Foot ulcers in people with diabetes mellitus are a common and serious global health issue. Dressings form a key part of ulcer treatment, with clinicians and patients having many different types to choose from including alginate dressings. A clear and current overview of current evidence is required to facilitate decision-making regarding dressing use. ⋯ Currently there is no research evidence to suggest that alginate wound dressings are more effective in healing foot ulcers in people with diabetes than other types of dressing however many trials in this field are very small. Decision makers may wish to consider aspects such as dressing cost and the wound management properties offered by each dressing type e.g. exudate management.
