The authors must be applauded for their honesty in that they accept and demonstrate that glucose levels in the ICU are difficult to control, in which we find some solace.
Tac to CSA conversion therapy in patients who fail to achieve target glycemic control or in those with difficult to control diabetes has yielded variable results.
The outbreaks in the Netherlands are difficult to control.
On the other hand, biases in registries are difficult to control.
Moreover, some outbreaks in Japan were difficult to control quickly, taking a mean of 46.5 days (range: 32 63) after the onset of index cases, partly due to secondary infections [ 25], emphasizing the need for early detection to prevent transmission.
In addition, changes in 'diagnostic behaviour' are difficult to control for.
In engineering, it is usually difficult to control CDNs by adding controllers to all nodes.
In particular, it is difficult to control nucleation because the molecular bonds in III-V semiconductors are highly covalent.
However, in a very severe lung disease, the rise in PaCO2 is sometimes difficult to control using conventional protective ventilation strategies.
Many diseases that can be relatively easily controlled in captive or domestic animals are very difficult to control in the wild (Krkošek et al. 2006).
