Group cognitive behavioural courses may reduce fatigue from rheumatoid arthritis

Fatigue can be one of the most difficult symptoms to cope with for people with rheumatoid arthritis and this study found that group cognitive behavioural courses may help. This NIHR-funded study compared six weekly group sessions plus a booster session with a single brief one-to-one meeting. Both groups also received an educational booklet. It took ...

Working in groups with ongoing support is valued by people with severe obesity trying to lose weight

People with severe obesity, a BMI of 35kg/m² or more, value the support and motivation they get from weight management programmes that include group-based interventions. However, commissioners and service managers should consider how to maintain adequate support and motivation once programmes end. Although previous studies have assessed the impact of non-surgical weight management programmes for ...

MRI and ultrasound scans are both helpful in assessing Crohn’s disease; MRI is slightly more accurate

Two types of scan, MRI and ultrasound, work well when used for staging and monitoring Crohn’s disease. MRI is more accurate. Researchers compared a form of magnetic resonance (MR) imaging that includes an oral contrast agent, with ultrasound scans. They aimed to see which was better able to detect the presence and extent of active ...

‘As-needed’ combination asthma inhalers can be more effective than regular inhaled steroids

In adults with mild to moderate asthma, budesonide-formoterol used as needed for symptom relief was more effective at preventing severe exacerbations than maintenance low-dose budesonide plus as-needed terbutaline. In this trial involving 885 adults, those using the combination inhaler as required had fewer severe asthma attacks, with similar levels of general symptom control, and overall ...

Longer duration of urinary catheter placement associated with an increase in urinary infection

The risk of urinary infection appears low with very short-term use but increases with the time that a patient has a catheter. Women and patients with paraplegia or cerebrovascular disease are at increased risk. This US-based retrospective analysis of electronic health records identified 148,361 indwelling catheterisations, of which 61,047 were for three or more days, ...

Holistic services in advanced lung disease can help people cope better with breathlessness

Services providing holistic health care can improve the psychological well-being of people who are living with breathlessness associated with chronic or advanced lung disease, such as lung cancer or chronic obstructive pulmonary disease. Breathlessness is a distressing symptom in which feelings of fear and helplessness, social isolation, high levels of anxiety and significant carer burden ...

Twenty mph speed zones reduce the danger to pedestrians and cyclists

Introducing 20mph speed zones reduces road traffic accidents, including those suffered by pedestrians and cyclists. Speed zones use physical obstacles such as road narrowing, speed bumps and chicanes, whereas speed limits only use signs and lines. The evidence was inconclusive on whether limiting speed to 20mph alone was effective, without the traffic calming. There was ...

Voucher rewards do not reduce frequency of cannabis use or relapse in people with early psychosis

Contingency management - the use of positive reinforcement in the form of supermarket vouchers to shape behaviour - makes no difference in the frequency of cannabis use or relapse rates in those with early psychosis. Although psychotic symptoms initially decrease, these changes are not sustained over the longer term and are no better than with ...

Very small babies appear not to be affected by the rate of increasing milk feeds

A large-scale trial has found that the speed of increasing milk feed volumes in low birth weight or very low gestational age babies who are on intravenous feeding does not influence outcomes. This NIHR-funded study randomised preterm (below 32 weeks) or very low birth weight (less than 1,500g) babies to receive either daily milk feed ...

Taking blood pressure medications at night seems best

People who took their blood pressure medications at bedtime were 45% less likely to experience a major cardiovascular outcome, such as heart attack or stroke, compared with people who took them in the morning. Most blood pressure medications, diuretics aside, do not have a recommended time of administration. A large trial conducted across 40 general ...
