RESUMEN
INTRODUCTION: This study utilized continuous glucose monitoring data to analyze the effects of switching to treatment with fast-acting insulin aspart (faster aspart) in adults with type 1 diabetes (T1D) in clinical practice. METHODS: A noninterventional database review was conducted in Sweden among adults with T1D using multiple daily injection (MDI) regimens who had switched to treatment with faster aspart as part of basal-bolus treatment. Glycemic data were retrospectively collected during the 26 weeks before switching (baseline) and up to 32 weeks after switching (follow-up) to assess changes in time in glycemic range (TIR; 70-180 mg/dL), mean sensor glucose, glycated hemoglobin (HbA1c) levels, coefficient of variation, time in hyperglycemia (level 1, > 180 to ≤ 250 mg/dL; level 2, > 250 mg/dL), and time in hypoglycemia (level 1, ≥ 54 to < 70 mg/dL; level 2, < 54 mg/dL) (ClinicalTrials.gov Identifier NCT03895515). RESULTS: Overall, 178 participants were included in the study cohort. The analysis population included 82 individuals (mean age 48.5 years) with adequate glucose sensor data. From baseline to follow-up, statistically significant improvements were reported for TIR (mean increase 3.3%-points [approximately 48 min/day]; p = 0.006) with clinically relevant improvement (≥ 5%) in 43% of participants. Statistically significant improvements from baseline were observed for mean sensor glucose levels, HbA1c levels, and time in hyperglycemia (levels 1 and 2), with no statistically significant changes in time spent in hypoglycemia. CONCLUSIONS: Switching to faster aspart was associated with improvements in glycemic control without increasing hypoglycemia in adults with T1D using MDI in this real-world setting.
RESUMEN
Modulation in ventilatory settings is one of the approaches and interventions used to treat and prevent secondary brain damage after traumatic brain injury (TBI). Here we investigate the effect of hyperoxia in combination with hypoventilation on brain oxygenation, metabolism and intracranial pressure. Twelve pigs were divided into three groups; group1-100% hyperoxia (n=4), group 2-100% hyperoxia and 20% decrease in minute volume (MV) (n=4) and group 3-100% hyperoxia and 50% decrease in MV (n=4). Neither of the ventilator settings affected the lactate/pyruvate ratio significantly. However, there was a significant decrease of brain lactate (2.6±1.7 to 1.8±1.6mM) and a rapid and marked increase in brain oxygenation (7.9±0.7 to 61.3±17.6mmHg) in group 3. Intracranial pressure (ICP) was not significantly affected in this group, however, the ICP increased significantly in group 2 with 100% hyperoxia plus 20% reduction in minute volume. We conclude that hyperoxia in combination with 50% decrease in MV showed pronounced increase in partial brain oxygen tension (pbrO2) and decrease in brain lactate. The ventilatory modification, used in this study should be considered for further investigation as a possible therapeutic intervention for TBI patients.
