Long-term shelf stability of amphiphilic β-cyclodextrin nanosphere suspensions monitored by dynamic light scattering and cryo-transmission electron microscopy

Amphiphilic β-cyclodextrins (βCDa) were synthesized by statistically grafting hexanoyl carbon chains on the secondary hydroxyl functions of the βCD glucopyranosyl units. The obtained derivative was used to prepare sub-micronic colloidal nanosphere suspensions using a nano-precipitation method. The fresh suspensions contained particles with a diameter ranging from 60–100?nm. Taking into account that the physical stability of colloidal systems remains one of the major problems which can restrict their use in pharmaceutical particulate carrier formulations, the long-term stability of the aqueous nano-dispersions was investigated. Two complementary characterization methods, namely dynamic light scattering and cryo-transmission electron microscopy, were used to control the size distribution and morphology of the nanospheres during storage. The zeta potential was measured as well. An unexpected good physical stability of the suspensions after 3 year storage at room temperature was observed. This behaviour appears to be related to the small size and structural organization of the nanoparticles. The mean diameters determined from light scattering experiments are consistent with those measured from electron micrographs. The slight difference between the values obtained by both methods is discussed.

Hard to heal pressure ulcers (stage III-IV): Efficacy of injected activated macrophage suspension (AMS) as compared with standard of care (SOC) treatment controlled trial

The objective of this study was to compare local injections of AMS with SOC treatments for stage III and IV pressure ulcers in elderly patients. It was designed as historically prospective 2-arms non-parallel open controlled trial, and conducted in a department of geriatric medicine and rehabilitation of a university affiliated tertiary hospital. We studied 100 consecutive elderly patients with a total of 216 stage III or IV pressure ulcers, 66 patients were assigned to the AMS group and had their wounds injected, while 38 patients were assigned to the SOC group. Primary outcome was rate of complete wound closure. Time to complete wound closure and 1-year mortality served as secondary outcomes. Statistical analyses were performed at both patient and wound levels. Percentage of completely closed wounds (wound level and patient level) were significantly better (p < 0.001/p < 0.001, respectively) in all patients in favor of AMS, as well as in the subset of diabetic patients (p < 0.001/p < 0.001). Similarly, AMS proved significantly better for the subset of those with leg ulcers and with baseline wounds ≤15 cm², compared with SOC. There were no statistically significant differences with regard to time to complete closure or 1-year mortality rates in the two groups. It is concluded that there is a significant difference in favor of stage III and IV wound closure rates by AMS, as compared with SOC treatments.
