TO THE EDITOR—We thank Dr Mc-Donald for his interest in our work and concur that the role of particular ribo-types in the clinical outcome of Clostrid-ium difficile infection (CDI) is complex [1]. Our study identified several factors that predicted severe CDI in unadjusted analysis, including ribotype 027/078 (Table 2 in our article) [2]. We agree that including intermediate white blood cell (W...

McDONALD INSTITUTE MONOGRAPHS

John Corbett McDonald.

In the study of work related diseases, John Corbett McDonald was a pioneering investigator, whose research and techniques in many ways defined occupational epidemiology. His best known role from the mid-1960s onwards—analysing the effects on health of different forms of asbestos—yielded controversy in a highly contentious field. An inspiration to epidemiologists worldwide, McDonald produced res...

McDonald et al.pmd

High frequency (> 1 Hz) repetitive transcranial magnetic stimulation (rTMS) applied to the left prefrontal cortex and low frequency (≤ 1 Hz) rTMS applied to the right prefrontal cortex have shown antidepressant effects. However, the clinical significance of these effects has often been modest. It was hypothesized that a combination of these two techniques might act synergistically and result in...

George McDonald Church (1954- )

George McDonald Church studied DNA from living and from extinct species in the US during the twentieth and twenty-first centuries. Church helped to develop and refine techniques with which to describe the complete sequence of all the DNA nucleotides in an organism's genome [4], techniques such as multiplex sequencing, polony sequencing, and nanopore sequencing. Church also contributed to the Hu...
