New drugs for deep vein thrombosis may offer a safe alternative to warfarin

This Cochrane systematic review found that two new types of drugs taken by mouth for deep vein thrombosis were as effective as standard treatment, which most commonly involves treatment by injection followed by warfarin tablets for at least three months. The new drugs have the advantage that they do not require monitoring or dose changes ...

Self-management support for stroke survivors may improve independence

This NIHR-funded summary of systematic reviews looked at the evidence on self-management support for stroke survivors. It found that the term self-management was rarely used in the literature. There was high quality evidence that therapy-based rehabilitation, some of it including components supporting self-management, had a beneficial effect on the basic activities of daily living, such ...

This NIHR-funded systematic review aimed to assess the effectiveness of talking therapies in improving outcomes for people with non-specific low back pain.

First, the technologies need to help people living with disease to build effective relationships with doctors, nurses and others. Second, there needs to be a good fit between the technology and everyday routine of the patient. Thirdly, the ...

Pyoderma gangrenosum is a rare serious skin condition causing painful ulcers, and over half of ulcers had failed to heal after six months of either treatment. There were more serious side effects – ...

A hormone-releasing coil is best for relieving heavy periods

This Cochrane systematic review of trials found that a progesterone releasing coil device (mainly Mirena®) inserted in the womb was more effective at reducing heavy periods than taking oral tablets. The coil led to more minor side effects, but improved quality of life, compared with tablets. Surgical removal of the womb, hysterectomy, was more effective ...
