Despite improvements in our knowledge of the physiopathology of severe infection and the evolution of diagnostic methods, antibiotic therapy, postoperative care and surgical techniques, a substantial number of patients develop severe intra-abdominal infection and advanced stages of septic insult requiring admission to the ICU.
In part, the discordant age estimates can be explained through reference to the genuine time-lag (δ True MA-FA ; see Figure 1) between the divergence of genetic lineages (predating speciation) and the evolution of diagnostic morphological characters (postdating speciation).
The evolution of diagnostic criteria for PMS has a confusing and controversial history that has led to frustration among scholars and caregivers who are unclear of what symptoms constitute either disorder.
The underestimation of speciation times from fossil data (δ Fossil error ) can be partitioned into two components: (i) the interval, following speciation, required for diagnostic characters to evolve (δ Diagnostic character ); and (ii) the time, following the evolution of diagnostic characters, realized for the deposition of a sampled fossil (δ Oldest fossil ).
Moreover, the limited time frame of a common RCT does not allow assessment of long-term outcomes or risks related to testing (e.g. radiation risk due to imaging tests) and technological evolution of diagnostics may render the RCT results quickly out-dated.
Lack of uniform definition of AE-COPD hampers international comparisons and the evolution of uniform diagnostic testing and treatment guidelines [ 19].
Also the effect of analgesics on the evolution of signs, diagnostic accuracy and outcome were surveyed.
Its epidemiology has been difficult to study because of its rarity and evolution in diagnostic and coding practices.
A few minutes of diagnostics, and Linda had his number.
Finally, as in previous French analyses, we assumed that the period effect, if any, would mainly be due to variations in the efficiency of surveillance systems and evolution of the diagnostic tests [ 12].
