Future mental health care may include diagnosis via brain scan and computer algorithm

 Most of modern medicine has physical tests or objective techniques to define much of what ails us. Yet, there is currently no blood or genetic test, or impartial procedure that can definitively diagnose a mental illness, and certainly none to distinguish between different psychiatric disorders with similar symptoms. Experts are combining machine learning with brain imaging tools to redefine the standard for diagnosing mental illnesses.

NIHR Signal 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 single gene can be misdiagnosed as type 1 diabetes, leading to unnecessary insulin treatment. Those recruited for this study were 98% white and tested at an average of 14 years after diagnosis.

Signal Single urine samples are just as good as 24-hour collections for diagnosing pre-eclampsia

The urine spot albumin-creatinine ratio (which is done on a single, on-the-spot sample) reliably identified 99% of pregnant women with high blood pressure who went on to develop severe pre-eclampsia. The spot protein-creatinine ratio, as currently recommended by NICE, was slightly less sensitive identifying over 90% of women. Both spot tests were good value for money.


Nearly 1,000 women, suspected of having pre-eclampsia, took part in this NIHR-funded study, in 36 UK obstetric units. They had high blood pressure and protein detected in their urine (by dipstick) beyond 20 weeks of pregnancy. The study compared the diagnostic accuracy of newer ways of ‘spot’ testing a single sample of urine for predicting severe pre-eclampsia with traditional tests on a urine sample taken over 24-hours.

Plasma EGFR mutation tests for adults with locally advanced or metastatic non-small-cell lung cancer [MIB 137}

New:  Medtech innovation briefing


Epidermal growth factor receptor (EGFR) mutation tests are in vitro diagnostic (IVD) tests used to help identify adults with non-small-cell lung cancer (NSCLC) suitable for treatment with EGFR tyrosine kinase inhibitors (EGFR‑TKIs). The presence of specific EGFR mutations show how effective treatment with EGFR‑TKIs will be. As a result, the test is useful for oncologists for deciding personalised treatment options.


EGFR mutations occur in EGFR exons 18–21 and mutations in exons 18, 19 and 21 and indicate suitability for treatment with EGFR‑TKIs. Mutations in exon 20 (with the exception of a few mutations) show the tumours are EGFR‑TKI resistant and not suitable for treatment with EGFR‑TKIs.

Point-of-care creatinine tests before contrast-enhanced imaging [MIB 136]

New:  Medtech innovation briefing


POC creatinine tests allow rapid measurements of creatinine levels using very small samples of whole blood, serum, plasma or a combination of these. The devices used for these tests are either handheld or table-top and need blood from either finger-prick or venous/arterial samples. The method of analysis can vary with some devices using test cartridges and some using test strips.


The focus of this briefing is POC creatinine testing to assess kidney function in people who are scheduled to have contrast-enhanced imaging. Testing is important because contrast materials such as iodine or gadolinium can cause kidney injury, particularly in high-risk patients and those with known kidney dysfunction. If patients do not have a recent creatinine measurement, their imaging may be cancelled and rescheduled. Alternatively, they may have unenhanced imaging – which is less reliable – or the planned contrast agent may be given, risking kidney injury. Current practice varies; a recent UK survey estimated that up to 20% of hospitals only check creatinine levels before imaging in people known to be at high risk of kidney injury (Harris et al. 2016).


MammaTyper in vitro diagnostic test for determining breast cancer subtypes [MIB 135]

New:  Medtech innovation briefing


The MammaTyper (BioNTech Diagnostics GmbH) test is a molecular in vitro diagnostic test for the relative gene expression quantification of the genes ERBB2, ESR1, PGR and MKI67 in human breast cancer tissue. It is used as a diagnostic test on biopsy samples of invasive breast cancer tissue from surgical resection or pre-operative core needle biopsies. The test is based on reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR). MammaTyper classifies breast cancer into 4 subtypes that have different treatments according to St Gallen (2017) guidelines:
  • Luminal A-like (oestrogen receptor [ER]-positive and generally human epidermal growth receptor 2 [HER2]-negative); treated with endocrine therapy.
  • Luminal B-like subdivided according to the ERBB2 expression into:
    • luminal B-like (ER-negative and HER2-positive); treated with anti-HER2 therapy and chemotherapy
    • luminal B-like (ER-positive and generally HER2-negative); treated with endocrine therapy.

  • HER2-positive (non-luminal); treated with anti-HER2 therapy and chemotherapy.
  • Triple-negative (generally ER, progesterone receptor [PR]- and HER2-negative); treated with chemotherapy.

Point-of-care and home faecal calprotectin tests for monitoring treatment response in inflammatory bowel disease [MIB132]

New medtech innovation briefing from NICE:

Elevated faecal calprotectin (FC) is a marker of intestinal inflammation, including that caused by inflammatory bowel disease (IBD). NICE diagnostics guidance recommends FC testing for the diagnosis of IBD; this briefing summarises the available information on the use of FC to monitor treatment response in patients with IBD.

There are 3 types of FC test available: point of care (used by healthcare professionals), home use (used by patients or carers) and laboratory (used by laboratory scientists). This briefing includes only point‑of‑care and home‑use tests because laboratory tests are widely available in the NHS, although their usage varies.

Survey of Dermatologists and Venereologists Shows Varying Approach to Penile Biopsies

J Clin Aesthet Dermatol. 2017;10(10):26–27

Objective. To determine frequency of use and safety of epinephrine containing local anesthesia among dermatologists in the United Kingdom and venereologists undertaking penile biopsy.

Conclusion. Use of epinephrine-containing local anesthesia is common among physicians in the United Kingdom undertaking penile biopsies. Despite this, no episodes of necrosis were observed. While further investigation is still required, it is likely that use of epinephrine-containing local anesthesia is safe for local penile injection.

Tests in secondary care to identify people at high risk of ovarian cancer [DG321

New: Diagnostic Guidance

Evidence-based recommendations on tests in secondary care to identify people at high risk of ovarian cancer. The tests are the IOTA ADNEX model, Overa (MIA2G), RMI I (at thresholds other than 250), ROMA and IOTA Simple Rules.

There is currently not enough evidence to recommend the routine adoption of the IOTA ADNEX model, Overa (MIA2G), RMI I (at thresholds other than 200 or 250), ROMA or IOTA Simple Rules in secondary care in the NHS to help decide whether to refer people with suspected ovarian cancer to a specialist multidisciplinary team (MDT).

NIHR Signal Placing wet gauze on babies’ tummies speeds up urine collection

Almost a third of infants managed to urinate within five minutes after a painless, cheap technique that stimulates the skin, compared with 12% of infants observed only, as is standard practice.

The ‘Quick-Wee’ method involved rubbing the babies’ abdomens gently with gauze soaked in cold saline before collecting urine. This trial was carried out with 354 babies aged one to 11 months in one Australian paediatrics emergency room.

NICE guidelines recommend non-invasive ‘clean catch’ collection if possible but this can be difficult, especially in young children. They estimate that 20 minutes of staff time can be needed to obtain a sample. Hospital paediatrics settings and primary care may want to try this promising, cheap and safe technique.

There was no difference in rates of contamination and it may reduce the number of babies who need to go on to the less desirable collection by pad samples or invasive techniques.

Detecting Eating Psychopathology in Female Athletes by Asking About Exercise: Use of the Compulsive Exercise Test

Use of the Compulsive Exercise Test. Eur. Eat. Disorders Rev., 25: 618624. doi: 10.1002/erv.2561.

The present study assessed the suitability of the Compulsive Exercise Test (athlete version; CET-A) for identifying female athletes with clinically significant features related to or comparable with eating psychopathology. Three hundred and sixty-one female athletes (including 12 with a clinically diagnosed eating disorder) completed the Eating Disorders Examination Questionnaire and the CET-A. Receiver operating curve analysis was employed to identify a cut-off value on the CET-A, which could indicate clinically significant features related to or comparable with eating psychopathology among female athletes. The analysis demonstrated that a CET-A score of 10 successfully discriminated female athletes with a current eating disorder. The results suggest that the CET-A may be a suitable tool for detecting eating psychopathology in female athletes. Additional longitudinal research is needed to evaluate the predictive value of the CET-A.
