Mesothelioma mortality in Great Britain from 1968 to 2001.

BACKGROUND: The British mesothelioma register contains all deaths from 1968 to 2001 where mesothelioma was mentioned on the death certificate. AIMS: To present summary statistics of the British mesothelioma epidemic including summaries by occupation and geographical area. METHODS: Standardized mortality ratios (SMRs) were calculated for local authorities, unitary authorities and counties. Temporal trends in SMRs were also examined. Proportional mortality ratios (PMRs) were calculated using the Southampton (based on the 1980 standard occupational classification) coding scheme. Temporal trends in PMRs were also examined. RESULTS: The annual number of mesothelioma deaths has increased from 153 in 1968 to 1848 in 2001. Current deaths in males account for about 85% of the cases. The areas of West Dunbartonshire (SMR 637), Barrow-in-Furness (593), Plymouth (396) and Portsmouth (388) have the highest SMRs over the period 1981-2000. The occupations with the highest PMRs are metal plate workers (PMR 503), vehicle body builders (526), plumbers and gas fitters (413) and carpenters (388). CONCLUSIONS: These data reinforce earlier findings that geographical areas and occupations associated with high exposure to asbestos in the past continue to drive the mesothelioma epidemic in Great Britain. However, the trends over time suggest a change in the balance of risk away from traditional asbestos exposure industries to industries where one could describe the exposure as secondary, such as plumbers and gas fitters, carpenters, and electricians

Proportion of Pelvic Inflammatory Disease caused by Chlamydia trachomatis: consistent picture from different methods

Background. Pelvic inflammatory disease (PID) is a leading cause of both tubal factor infertility and ectopic pregnancy. Chlamydia trachomatis is an important risk factor for PID, but the proportion of PID cases caused by C. trachomatis is unclear. Estimates of this are required to evaluate control measures. Methods. We consider 5 separate methods of estimating age-group-specific population excess fractions (PEFs) of PID due to C. trachomatis, using routine data, surveys, case-control studies, and randomized controlled trials, and apply these to data from the United Kingdom before introduction of the National Chlamydia Screening Programme. Results. As they are informed by randomized comparisons and national exposure and outcome estimates, our preferred estimates of the proportion of PID cases caused by C. trachomatis are 35% (95% credible interval [CrI], 11%–69%) in women aged 16–24 years and 20% (95% CrI, 6%–38%) in women aged 16–44 years in the United Kingdom. There is a fair degree of consistency between adjusted estimates of PEF, but all have wide 95% CrIs. The PEF decreases from 53.5% (95% CrI, 15.6%–100%) in women aged 16–19 years to 11.5% (95% CrI, 3.0%–25.7%) in women aged 35–44 years. Conclusions. The PEFs of PID due to C. trachomatis decline steeply with age by a factor of around 5-fold between younger and older women. Further studies of the etiology of PID in different age groups are required

Objective Measurement of Blood Loss following Vaginal Delivery in a UK Hospital

Background: Postpartum haemorrhage (PPH) is the leading cause of maternal morbidity and mortality worldwide. The reported incidence of PPH varies globally, which is often due to the use of subjective visual estimation of blood loss. The aim of this study was to measure the rate of PPH and severe PPH at a UK hospital using objective measurement of blood loss. Methods: Blood loss after vaginal birth was objectively measured in 2009 women at Birmingham Women’s Hospital, UK using a blood collection drape. Results: The postpartum haemorrhage rate, defined as blood loss of 500 mL or more, was 22.2%. The severe PPH rate, defined as blood loss of 1000 mL or more, was 5.3%. Conclusions: The objective measurement of blood loss following vaginal birth is necessary for the accurate calculation of PPH rates

The reliability of the McCabe score as a marker of co-morbidity in healthcare-associated infection point prevalence studies

This study aimed to ascertain the reliability of the McCabe score in a healthcare-associated infection point prevalence survey.   A 10 European Union Member States survey in 20 hospitals (n = 1912) indicated that there was a moderate level of agreement (κ = 0.57) with the score. The reliability of the application of the score could be increased by training data collectors, particularly with reference to the ultimately fatal criteria. This is important if the score is to be used to risk adjust data to drive infection prevention and control interventions
