Urinary thrombomodulin levels were significantly higher following occupational exposure to chemicals, in the presence of dipstick protein, but not in the presence of dipstick blood

Currently, there are no biomarkers which can identify patients with an increased risk of developing urothelial cancer as a result of occupational chemical exposure. The aim of this study was to evaluate the relationships between final diagnosis and 22 biomarkers measured in urine, serum and plasma collected from 156 hematuric patients. Fourteen of the 80 patients (17.5%) with urothelial cancer and 13/76 (17.1%) of the controls were deemed to have a history of chemical exposure. We applied Fisher's exact tests to explore associations between chemical exposure and final diagnosis, and tumor stage and grade, where applicable; ANOVA and t-test to compare age across patients with and without chemical exposure; and Zelen's exact test to evaluate relationships across final diagnosis, chemical exposure and smoking. Following pre-selection of biomarkers using Lasso, we identified biomarkers with differential levels across patients with and without chemical exposure using Welch's t-test. Using a one-sided t-test and considering multiple testing using FDR, we observed that TM levels in urine were significantly higher in samples from patients with a history of chemical exposure regardless of their diagnosis as control or urothelial cancer (one-sided t-test, p_UC = 0.014 and p_CTL = 0.043); in the presence of dipstick protein and when urinary pH levels ≤ 6 (p = 0.003), but not in the presence of dipstick blood (p = 0.115). Urothelial cancer patients with a history of chemical exposure were significantly younger (64.1 years) than those without chemical exposure (70.2 years) (one-sided t-test p-value = 0.012); and their tumors were higher grade (Fisher's exact test; p = 0.008). There was a strong association between a history of chemical exposure and smoking in urothelial cancer patients (Zelen's exact test; p = 0.025). Elevated urinary thrombomodulin levels could have the potential to identify chemical exposure in hematuric patients at high risk of developing urothelial cancer.

Reassessing the impact of yesterday's men

This special seminar to explore the controversy surrounding the Yesterday's Men programme of 1971, and its subsequent significance in the history of British political documentaries, was held at the Institute of Historical Research, London, on 26 January 1994. The seminar opened with a re‐screening of the programme, which featured interviews with Harold Wilson, the then leader of the opposition to Edward Heath's new Conservative government, front bench opposition spokesmen including Roy Jenkins, Tony Crosland and Denis Healey, and the political correspondent Peter Jenkins. The discussion was introduced by Dr Jean Seaton and chaired by Professor Peter Hennessy. The principal participants were Joe Haines (Chief Press Secretary to Harold Wilson 1969–76), Brian Wenham (editor, Panorama 1969–71, Head of BBC Current Affairs Group 1971–78) and John Grist (Head of BBC Current Affairs Group 1967–71, Controller, BBC English Regions 1972–77), with further contributions from Philip Whitehead, Professor Ben Pimlott, Peter Rose, David Benn, Professor Colin Seymour‐Ure, Joanna Kayford, Rosaleen Hughes, Hugh Purcell, Murray Weston and Chloe Miller.
