Validation of Continuous Glucose Monitoring in Children and Adolescents With Cystic Fibrosis: A prospective cohort study

OBJECTIVE: To validate continuous glucose monitoring (CGM) in children and adolescents with cystic fibrosis. RESEARCH DESIGN AND METHODS: Paired oral glucose tolerance tests (OGTTs) and CGM monitoring was undertaken in 102 children and adolescents with cystic fibrosis (age 9.5-19.0 years) at baseline (CGM1) and after 12 months (CGM2). CGM validity was assessed by reliability, reproducibility, and repeatability. RESULTS: CGM was reliable with a Bland-Altman agreement between CGM and OGTT of 0.81 mmol/l (95% CI for bias +/- 2.90 mmol/l) and good correlation between the two (r = 0.74-0.9; P < 0.01). CGM was reproducible with no significant differences in the coefficient of variation of the CGM assessment between visits and repeatable with a mean difference between CGM1 and CGM2 of 0.09 mmol/l (95% CI for difference +/- 0.46 mmol/l) and a discriminant ratio of 13.0 and 15.1, respectively. CONCLUSIONS: In this cohort of children and adolescents with cystic fibrosis, CGM performed on two occasions over a 12-month period was reliable, reproducible, and repeatable

Comparing Total Neoplasms, Breast & Prostate Cancer Mortality Rates of the UK and 20 Major Developed Countries 1989-91 v 2013- 15 - Identifying Progress

Introduction: Britain’s cancer survival results have been criticised as being significantly higher than twenty Major Developed Countries (MDC). Hence this comparison of current UK Total Age-StandardisedDeath-Rates (ASDR), female Breast and Prostate cancer mortality rates with twenty (MDC) between1989 to 2015 to determine any significant change. Method: WHO data ASDR per million (pm) for Total, Breast and Prostate cancer mortality rates examined for the years 1989-91 to 2013-15. Confidence Intervals (+/- 95%) are used to determine any significant differences between the UK and other country’s outcomes over the period. Chi square tests for each nation’s Breast and Prostate mortality. Results: Every country’s Total ASDR, Breast and Prostate cancer mortality fell except Greece and Japan. Total ASDR Male cancer mortality rates ranged from Portugal 1653pm to Sweden 1232pm. UK at 1475pm were 10th but had been 6th highest. Total ASDR Female rates went from Denmark’s 1176pm to Japan’s 740pm, the UK 1092pm now 5th but previously had been second highest. No country’s Total rates fell significantly more than Britain’s who had significantly bigger reductions than four other countries for both sexes. Breast mortality ranged from Ireland’s 206pm to Japan’s 99pm, UK rates fell significantly more than five countries. Whilst Breast mortality fell in every country Norway and UK had significantly bigger reductions in Breast than Prostate deaths, conversely France’s Prostate rates fell more than Breast mortality. Prostate mortality went from Norway 213pm Japan’s 60pm, the UK 167pm and five countries had greater reductions than Britain. Conclusions: Results reflect well on UK services for Total and Breast cancers, showing the NHS achieving more with proportionately less as Britain spends less on health than most MDC. The need how to improve UK prostate results are briefly discussed, such as a public information campaign to match the successful Breast cancer aware programme of the 1990’s

Genetic Determinants and Epidemiology of Cystic Fibrosis–Related Diabetes: Results from a British cohort of children and adults

OBJECTIVE—Longer survival of patients with cystic fibrosis has increased the occurrence of cystic fibrosis–related diabetes (CFRD). In this study we documented the incidence of CFRD and evaluated the association between mutations responsible for cystic fibrosis and incident CFRD, while identifying potential risk factors
