Dr Peacock and Dr Douiri publish in the Journal of Allergy and Clinical Immunology

MedStats team members, Dr Peacock and Dr Douiri publish a study titled: ‘Intradermal Grass Pollen Allergen Immunotherapy for Seasonal Allergy: A Randomized Controlled Trial’

The study aimed to ‘evaluate the efficacy and safety of grass pollen intradermal immunotherapy in the treatment of allergic rhinitis’. Using a randomized control trial, the authors concluded that ‘intradermal allergen immunotherapy suppressed skin late responses but was not clinically effective and resulted in worsening of respiratory allergic symptoms’.



MedStats team member, Dr Douiri, publishes protocol paper in BMJ Open

Dr Douiri, along with colleagues, has published a protocol in BMJ Open titled: ‘OPTIMUM: a protocol for a multicentre randomised controlled trial comparing Out Patient Talc slurry via Indwelling pleural catheter for Malignant pleural effusion vs Usual inpatient Management’.

Key Strengths and Limitations from the study were highlighted:

  • This is the first prospective randomised con- trolled trial primarily comparing quality of life (QoL) outcomes between inpatient and out- patient treatment pathways for malignant pleural effusion.
  • The primary outcome measure is clinically relevant.
  • Patients with non-expandable lung are also included in the study.
  • The study represents real life presentation and management.
  • A limitation is that patients with poor perform- ance status are not included and only patients with potential for ambulatory management are included. However, to include those patient groups a separate study design to answer that specific question will have to be conducted.


Dr Douiri publishes in BMJ Open

Dr Douiri, along with colleagues, has published in BMJ Open a study titled: ‘Desensitisation to cigarette package graphic health warnings: a cohort comparison between London and Singapore’.

The study ‘compared 2 sociocultural cohorts with different duration of exposure to graphic health warning labels (GHWL), to investigate a possible desensitisation to their use’ and ‘studied how a differing awareness and emotional impact of smoking- associated risks could be used to prevent this’. The authors concluded that ‘length of exposure to GHWL impacts on the effectiveness. However, acknowledging the different levels of awareness and emotional impact of smoking-associated risks within different sociocultural cohorts could be used to maintain their impact’.



MedStats member, Dr Douiri, publishes in the Journal of Infection

The Journal of Infection has published a study titled ‘Baseline cytokine profiling identifies novel risk factors for invasive fungal disease among haematology patients undergoing intensive chemotherapy or haematopoietic stem cell transplantation‘. MedStats team member, Dr Douiri, was a co-author.

The study aimed to identify cytokine profiles that correlate with increased risk of invasive fungal disease (IFD). The authors concluded that ‘high baseline IL-2R and CCL2 concentrations were independent indicators of the risk of developing IFD and could be used to identify patients for enhanced prophylaxis and early antifungal therapy’.

Dr Douiri publsihes in the journal of Blood

Dr Douiri has recently published (along with colleagues) a study titled: ‘Survival in adults with sickle cell disease in a high-income setting’ in Blood.

The study evaluated ‘survival among adult patients with SCD [sickle cell disease] followed at a single center in the United Kingdom.’ The retrospective analysis concluded that ‘although life expectancy for a patient with SCD in the United Kingdom continues to improve, it still falls behind that in the general population in London’.

Dr Crichton publishes in Stroke

MedStats team member, Dr Crichton, publishes along with collegues a study in Stroke titled: ‘Effect of Exhaust- and Nonexhaust-Related Components of Particulate Matter on Long-Term Survival After Stroke’

The study using data from the South London Stroke Register concluded that ‘exposure to certain outdoor PM pollution, particularly PM2.5, increased mortality risk poststroke up to 5 years after the initial stroke’.

Dr Douiri publishes in Critical Care Medicine

Dr Douiri (MedStats team member) publishes, along with colleagues in Critical Care Medicine, a study titled: ‘Effect of Continuous Renal Replacement Therapy on Outcome in Pediatric Acute Liver Failure’

The study aimed to ‘establish the effect of continuous renal replacement therapy on outcome in pediatric acute liver failure’. Using a retrospective cohort design the authors concluded that ‘Continuous renal replacement therapy can be used successfully in critically ill children with pediatric acute liver failure to provide stability and bridge to transplantation’.

Dr Douiri publishes in Thorax (part of BMJ group)

MedStats member, Dr Douiri, and colleagues have published a study titled: ‘Physiotherapy, and speech and language therapy intervention for patients with refractory chronic cough: a multicentre randomised control trial’

The study investigated whether physiotherapy, and speech and language therapy intervention (PSALTI) is effective for patients with refractory chronic cough. Using a multi-centred randomised controlled trial, the study found that PSALTI ‘significantly reduced objective cough frequency and significantly improved health related quality of life when compared with control intervention’.


UMS member Fiona Reid appointed as Senior Fellow of the Higher Education Academy

Congratulations to Fiona Reid, Senior Lecturer in Medical Statistics, who recently became a Senior Fellow of the Higher Education Academy.

Her reflective portfolio looked at a pedagogy for teaching applied statistics to medical students and health professionals; the lessons for academic teaching from the world of outdoor education; and the challenges of developing a postgraduate framework for sharing core research modules across courses.

Professor Peacock collaborates on research with Dartmouth College US

UMS member Professor Peacock collaborates with colleagues from Dartmouth College US on study published in the Journal of Nutrition.

The study is titled:  Lifestyle and other factors explain one-half of the variability in the Serum 25-Hydroxyvitamin D response to cholesterol supplementation in health adults.

Researchers concluded that ‘the factors that most affected changes in serum 25(OH)D concentrations in response to cholecalciferol supplementation included sex, baseline serum 25(OH)D, supplement intake adherence, skin-covering clothes, physical activity, and season. Genetic factors did not play a major role’.

UMS Statisticians publish study on liver fibrosis for a NICE Guidance

UMS Statisticians, Dr Summers, Dr Douiri, Dr Wang, Dr Ayis, and Professor Peacock along with colleagues from Kings Technology Evaluation Centre (KiTEC) published this week in Applied Health Economics and Health Policy.

The study, as part of a NICE Medical Technology Guidance, investigated the use of Virtual Touch Quantification (VTR) to diagnose and monitor liver fibrosis in Hepatitis B and C.

In September 2015, NICE issued final guidance (MTG27) on this technology specifically in relation to liver fibrosis in patients with chronic hepatitis B or hepatitis C, and this study summarised this guidance and the evaluation process.

The study listed the following key points for decision makers:

  • Virtual Touch™ Quantification (VTq) is a software application used with Siemens Acuson ultrasound scanners to assess the stiffness of liver tissue and the stage of liver fibrosis.
  • The National Institute for Health and Care Excellence Medical Technology Evaluation Programme assessed the VTq software for use in people with hepatitis B or C and the External Assessment Centre estimated cost savings per patient for the VTq software in hepatitis patients was £53 when compared to transient elastography and £434 when compared to liver biopsy.
  • In September 2015, the VTq software was recommended for adoption within the National Health Service (NHS) for patients with hepatitis B or C for diagnosis and monitoring of liver fibrosis.

Professor Peacock publishes in Trials

Professor Peacock, as part of a collaboration with Dartmouth College US in Clinical trial methodology (funded by NIH), has pubslihed a study in Trials as senior author.

The study examines what factors might predict patients who will fail the run-in period that some drug trials have. This is important as if we knew why patients failed we might be able to stop it happening, which would then save time and money and gain a more representative sample included in trials.

Dr Wang published in Lancet

MedStats member Dr Wang is joint lead author of a study published this week in the Lancet titled: ‘Development and validation of a dynamic outcome prediction model for paracetamol-induced acute liver failure: a cohort study

The study funded by the Foundation for Liver Research developed prediction models for survival of patients will paracetamol-induced liver failure, and concluded that ‘the role and indications for emergency liver transplantation in paracetamol- induced acute liver failure require re-evaluation’.



MedStats team publish results of nationwide survey of SeHCAT utilisation

MedStats team members, Jennifer Summers, Janet Peacock, Bola Coker, Mercy Ofuya and Fiona Reid, along with colleagues, published results of their prospective survey of the provision and practise of SeHCAT (tauroselcholic [75 selenium] acid) for the diagnosis of Bile Acid Malabsorption.

The study was published in BMJ Open Gastroenterology.

The study was designed as a service evaluation of n=38 centres in the UK and captured  both centre and patient-level information; such as patient care-pathways, clinical history, SeHCAT results, treatment and aspects of follow-up.

The study ‘identified a lack of consistent cut-off/threshold values, with differing centre criteria for defining an ‘abnormal’ SeHCAT result’.

MedStats team publish study on Variation in Adverse Drug Reaction Product Information in BMJ Open

The study was published in the BMJ Open this month and was titled: ‘Variation in adverse drug reactions listed in product information for antidepressants and anticonvulsants, between the USA and Europe: a comparison review of paired regulatory documents‘.

Dr Victoria Cornelius (former member of the Medstats team, now at Imperial College) lead the study, along with Dr Kun Liu (Medstats member), Prof Janet Peacock (Medstats member) and Dr Odile Sauzet (associate member of the MedStats team).

This paper was dedicated to Kun Liu, our dear colleague, who sadly died in December 2015.

The comparison review study found notable variation in the product information sheets that list and describe adverse events for drugs between the UK and US versions. The authors suggest that this has implications for what is recognised as an adverse event and information which is given to patients.

MedStats team members, Dr Ayis & Ms Crichton, published in the Journal of Affective Disorders

Dr Ayis and Ms Crichton, along with co-authors from the Division of Health and Social Care Research at King’s College London, published the following article: The natural history of depression and trajectories of symptoms long term after stroke: The prospective south London stroke register’.

The study in the Journal of Affective Disorders tested the hypotheses that there are different trajectories of symptoms after stroke. Data was obtained from the South London Stroke Register (1998-2013).

Highlights from the study:

  • ‘Four patterns of development in depression symptoms after stroke were identified.’
  • ‘Mechanisms of change in symptoms over time vary across the four patterns.’
  • ‘For appropriate and timely interventions the varying needs should be observed.’
