‘Artificial pancreas’ improves glucose control in hospital patients with type 2 diabetes
Closed-loop insulin pumps, which continuously monitor blood glucose and administer insulin accordingly, can improve blood glucose control among patients with type 2 diabetes admitted to hospital for non-critical care. Those using the system spent about six hours longer in the target range, and this could hasten their recovery and reduce staff workload.
The number of hospitalised patients with type 2 diabetes is increasing. Glucose control often worsens during illness. Closed-loop pumps have bee...
MRI scan does not help to find the cause of pelvic pain in women
MRI scans are not sufficiently accurate to find the cause of chronic pelvic pain in women and should not replace laparoscopy (keyhole surgery), which can be used for diagnosis and often treatment. MRI only correctly ruled out a gynaecological condition in half of women judged to have no obvious cause and missed half of women who did have a treatable gynaecological condition.
Pinpointing the origin of chronic pelvic pain is often difficult due to the number of possible causes. If initial tests a...
Reminders help GPs to find and manage inherited cholesterol disorders
GPs and practice nurses assess more adults with inherited raised cholesterol (familial hypercholesterolaemia) when prompted by reminders. More patients have repeat cholesterol tests and assessments for heart disease, in line with NICE guidelines.
This NIHR-funded study used electronic health records from six GP practices to identify patients with total cholesterol greater than 7.5mmol/l. Reminder messages appeared when their records were opened during consultations and prompted GPs to carry out...
Ultrasound shows potential for confirming the diagnosis of pneumonia in children
Ultrasound scans of the lungs can be more accurate than chest X-rays for diagnosing pneumonia in children in some circumstances.
A review of the published evidence found that lung ultrasound was more sensitive (missed fewer cases) and about as specific (gave about the same number of false alarms) as chest X-ray, when used to confirm suspected community-acquired pneumonia in children. While pneumonia is a clinical diagnosis, X-ray is often used for confirmation.
Ultrasound also spares the child...
Self-monitoring improves control of high blood pressure compared with GP monitoring alone
Allowing patients who have inadequately controlled high blood pressure to monitor their own blood pressure at home helps their GPs to optimise their management. Patients who self-monitor and visit or talk to their GP when needed for medication adjustments achieve 4mmHg lower systolic blood pressure over 12 months compared with those relying only on the measurements made by a GP without self-monitoring.
Effects are similar if patients write down their measurements to send to the GP or do so via ...
Atraumatic needles reduce headaches following lumbar puncture
Use of atraumatic needles rather than conventional needles for lumbar puncture more than halves the rate of post-procedure headache. Moreover, this improvement does not come at the expense of procedure success rates.
Lumbar puncture involves inserting a needle in the lower back into the spinal canal to collect cerebrospinal fluid for diagnosis, or to inject a treatment or anaesthetic into it.
A common side effect is a headache, often from leakage of fluid from the puncture. Atraumatic needles ...
Imaging is the only way to diagnose blood clots in pregnancy
No blood test can accurately tell if a pregnant or recently pregnant woman has a blood clot. All pregnant women with a suspected clot should continue to have imaging investigations as per current UK guidelines.
This NIHR-funded study recruited 328 pregnant or postpartum women with a suspected blood clot in the lung (pulmonary embolism) or leg (deep vein thrombosis). They had a blood test to measure the levels of 13 biomarkers, such as the D-dimer, to see if they could rule a blood clot in or ou...
Self-testing kits increase overall HIV testing uptake in men who have sex with men
Frequency of HIV testing in men who have sex with men may be increased by one additional test in a six month period when self-testing kits are used. Self-testing kits allow people to collect their finger-prick or saliva sample, perform the test and interpret the result themselves.
This global study found that first-time testers made up around a tenth of all self-testers in high-income countries such as the US or UK, but about a third of those in resource-limited countries. About a third of self...
Uncertain benefits of BNP blood tests to monitor heart failure treatment
In specialist clinics, using B-type natriuretic peptide (BNP) blood levels to guide treatment in people with chronic heart failure shows promise but did not improve survival for all groups. In this review, the benefit was only seen in patients aged less than 75, who survived an extra 1.5 years on average, and possibly those with poor heart function (reduced ejection fraction). However, there was a reduction in hospital admissions for heart failure for everyone.
BNP is a hormone released from th...
New screening pathway could help to identify a rare, single-gene form of diabetes
A screening pathway using blood and urine tests followed by two genetic (DNA) tests identified all people with a rare subtype of diabetes called monogenic diabetes. The screening pathway performed better than current practice based on age at diagnosis and family history which misses 63%. It is, therefore, a useful approach for ruling out this form of diabetes and probably cheaper overall than offering every young person with diabetes DNA testing.
Monogenic diabetes, caused by a mutation in a si...
