A behavioural intervention for obese pregnant women did not reduce risk of diabetes

This large NIHR-funded UK trial found that a behavioural intervention for obese pregnant women did not reduce their risk of developing diabetes during pregnancy, or having a baby born too large for the duration of pregnancy (large-for-dates). However, the intervention did reduce the mothers’ weight gain slightly and increased their physical activity. Women received advice ...

A simple postural change to the Valsalva manoeuvre (see Definitions) improves the effectiveness of this cheap, non-invasive means of treating supraventricular tachycardia - an abnormally fast heart rate over 100 beats per minute. The NIHR funded a pragmatic trial of the promising technique in ten hospital emergency departments in England. The trial found that laying ...

Inhaling a saline mist did not reduce the time in hospital for babies with bronchiolitis

In this NIHR-funded trial babies with a viral chest infection (acute bronchiolitis) were treated either with a strong saline mist (nebulised 3% hypertonic sodium chloride) with standard care or standard care alone. The stronger than usual, hypertonic saline mist had no effect on the time it took for babies to be ready for discharge, nor ...

Education can restore awareness of low blood glucose in people with type 1 diabetes

This systematic review found that a range of educational and technological interventions could help adults with type 1 diabetes regain awareness of when they have low blood glucose (hypoglycaemia). Nearly one in every three adults with type 1 diabetes stops noticing low blood sugar levels. This means they cannot take action quickly to prevent a ...

The structured interventions lasted between one and three years and included activities like organising dedicated clinics to monitor and adjust medication to meet ...

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

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. It found that cognitive behavioural therapies were more effective than no treatment and provided some benefit compared with other active treatments like physiotherapy with education, home and clinic based exercise, or to less active ...
