Or, more specifically, by a single absence at that meeting.
The vast majority of these staff were "patient-facing" e.g., clinical doctors and nurses, reception, etc.. Illness absence for each staff member was regarded as a single episode if the absence was for the same illness and on consecutive days, for example five days of absence due to influenza was counted as a single absence and attributed to the week of the first day of absence.
Thus the goal of this study was not to find one single cause of sickness absence but to look for common features during organizational changes and identify situations where the individual finds herself in a vulnerable position or in a protective scenario.
Most studies use a single sickness absence modality as outcome, e.g. number of absence days, any absence spell, or absence spells of a certain duration [ 5, 8, 11- 17].
The use of multiple indicators for tracking fecal contamination could circumvent the problem of single marker absence or presence and strengthen overall diagnoses of microbiological water quality [6], [7], [8], [9], [11].
Readings were filtered for single mapping, absence of N, and identity level over 70% before SNP detection.
These include 691 single probe absences and 179 double probe absences for S. lividans 66 relative to S. coelicolor M145, and 436 single probe and 114 double probe absences for S. lividans TK24, relative to S. coelicolor M145, respectively.
However, initially our confidence in the validity of single probe absences was less.
The results presented here regarding single probe absences provide evidence for recombination between the aspartate-specific adenylation domain modules (4, 5 & 7) of the CdaPS genes of the CDA biosynthetic gene cluster revealing them to be "mosaic" genes, relative to the corresponding S. coelicolor sequences.
Some limitations of this study should be taken into account including single center design, absence of blinding, exclusion of patients with suspected pneumonia at ICU admission, and absence of evaluation of microaspiration, colonization, or tracheal ischemia.
Children were excluded if they only had a single episode of absence (eg, a 2-week illness), a medical illness that could reasonably explain the absence, a known hospital admission or were known to have been on holiday or to be truanting.
