Abstract

A microfluidic approach is described for generating capsules of biopolymer hydrogels at room temperature and with good control of particle size distribution and internal structure. The time of gelation and/or the concentration of the cross-linking agent in the continuous phase are controlled in order to achieve control over the internal structure of biomicrogels from capsules to gradient microgels to microgels with a uniform structure.

21. HIV Postexposure Prophylaxis-in-Pocket ("PIP") for Individuals With Low-Frequency, High-Risk HIV Exposures.

Author

Tumarkin, Ethan, Heendeniya, Amila, Murphy, Pauline, Placido, Tania, Tan, Darrell H. S., and Bogoch, Isaac I.

Abstract

Background: On-demand preexposure prophylaxis may reduce one's risk of HIV acquisition; however, it is unclear if individuals with a very low frequency of HIV exposures are conferred adequate protection. We evaluated a novel approach dubbed HIV post-exposure prophylaxis-in-pocket ("PIP"), for individuals with a low frequency of high-risk HIV exposures. Setting: Two HIV clinics in Toronto, Canada, managing HIV prevention cases. Methods: A retrospective evaluation of patients referred to HIV clinics for preexposure prophylaxis between January 1, 2013, and September 30, 2017, inclusive. After counseling and education, selected patients were initiated on PIP if they were having very infrequent HIV exposures. Results: Thirty patients were prescribed PIP. Four patients (13.3%) used PIP during this study. There were no HIV seroconversions in 21.8 cumulative patient-years of PIP. Conclusions: PIP may be a useful HIV prevention modality for individuals with a very low frequency of HIV exposures. [ABSTRACT FROM AUTHOR]

Abstract

In this tutorial review we discuss recent advances in the application of microfluidics for the generation of microgels from synthetic and biological polymers. We summarize advantages and drawbacks of the current methods used in microfluidic synthesis and assembly of polymer microgels. Continuous microfluidic encapsulation of cells is discussed as an exemplary application of the microgels. The article is finalized with a perspective on future research in the field. The article will be of interest to chemists, cell biologists, pharmacologists, and medicinal chemists.
