This idea is reinforced by the few studies that report no substantial changes in cardiovascular parameters, even with such higher doses as 2 and 5 mg/kg of tramadol [ 40- 42].
Human studies have shown no substantial changes in hematologic, lipid, hepatic, thyroid, or urinary characteristics in populations exposed occupationally to perfluorinated chemicals (Olsen et al. 1999, 2003).
Stability studies demonstrated no substantial change in HEV RNA concentration after freeze drying or after 10 months of storage at −20°C (the usual temperature), +4°C, and +20 to +26°C, compared with samples stored at <−80°C.
Markers of preventive screening, such as retinopathy, neuropathy, dietary counseling, microalbuminuria, smoking habits, BMI, and physical activity, showed no substantial changes throughout the study (Table 2).
Although introducing hospitalists and intensivists previously was shown to reduce inpatient mortality [ 36- 39], no substantial changes in hospital staffing or work hours occurred during the study period.
No substantial changes in chemotherapy protocols were made during the study years.
No substantial changes in ocular signs or BCVA were observed throughout the study, and the safety profile of BRINZ/TIM-FC was similar to previous reports [ 12, 13].
No substantial changes were observed in these markers; however, it is possible that the study duration of 12 months was not sufficient to see any major changes.
No substantial changes in delivery room assistance or medical or nursing staff were made during the study period.
Thereafter there were no substantial changes.
