Consequently, we found a decrease in the vulnerability for trauma related symptoms with an increased duration in the bush, when the correlation between trauma symptoms and the duration in the bush is controlled for the number of self-experienced event types.
Subjects underwent a training program to learn to remain immobile in response to a vocal command: "reste!", for an increasing duration (5 to 60 seconds).
The program included successive steps, in which they had to maintain immobility for an increasing duration (from 5 to 60 seconds, cf. table 1).
Although we found no significant difference in response rates by genotype (P=0.75) (73.5% overall response rate, 71.4% for CC, 77.5% for CG and 69.0% for GG), comparison of response duration by genotype showed a trend for increased duration of transfusion independence with C-allele dosage; however, this did not reach statistical significance (P=0.51).
In patients with exacerbations of COPD, domiciliary use of benzodiazepines had no effect on mortality and hospital length of stay, but seemed to cause a higher need for and increased duration of noninvasive ventilation.
The evidence for increased duration causing an increased risk of VAI is conflicting with some studies suggesting an increasing risk with duration [ 3, 11, 13, 25, 51, 52] longer than 5 7 days, with others showing no association [ 4, 53- 56].
In addition, an engineered protein variant of human G6Pase, designed for increased duration of expression, showed superior efficacy to the wild-type sequence by maintaining improved fasting blood glucose levels and reductions in liver mass for up to 12 days post-dose.
Increases in duration of viral shedding would allow for increased duration of contact among infected and naive animals, as well as a larger time window for vectors to acquire virus from an infected host.
In a study of 87 cases from several US hospitals, Morabia and Wynder [ 13, 14] reported an odds ratio (OR) of BAC for current smoking of 3.9 (95% confidence interval 1.8, 8.7), an increase in OR for increasing duration and amount of smoking, and a protective effect of quitting.
There was a significant trend for increasing duration of disease and lower percentage of total brain volume (Ptrend < 0.001), lower percentage of gray matter (Ptrend < 0.001) and white matter (Ptrend < 0.001), and higher percentage of WMLs (Ptrend = 0.05) (Table 3).
