Role of precision medicine in obstructive sleep apnoea.

Obstructive sleep apnoea is a substantial clinical and public health problem because it contributes to harmful effects on quality of life, daytime symptoms, road traffic incidents, and cardiometabolic disease. Increasingly, obstructive sleep apnoea is recognised as a heterogeneous disease, and patients have varied susceptibility to long term complications and different responses to treatment. This narrative review summarises the current knowledge of precision medicine in obstructive sleep apnoea, particularly the role of symptom clusters, polysomnogram phenotypes, physiological endotypes, and circulating biomarkers in defining subtypes.

Circulating markers of oxidative stress and risk of incident cardiovascular events in obstructive sleep apnea.

Unlabelled: The identification of which patients with obstructive sleep apnea (OSA) are more likely to develop cardiovascular disease (CVD) remains a challenge. OSA causes oxidative stress (OS) which may contribute to CVD pathogenesis. Therefore, OS markers could be useful in risk-stratifying cardiovascular (CV) risk in OSA patients.

The rs579459 ABO gene polymorphism and risk of incident cardiovascular events in obstructive sleep apnea: a pilot study.

Purpose: We have previously shown that the TT genotype (rs579459 location of the ABO gene) is significantly associated with circulating levels of e-selectin in patients with suspected obstructive sleep apnea (OSA). We hypothesized that this genotype would be associated with incident cardiovascular disease (CVD).

Methods: Patients with suspected OSA who had a full diagnostic polysomnogram from 2003 to 2011 were recruited; CV events occurring within 8 years of polysomnography were identified by linkage to provincial health databases.

Microfluidics-based fabrication of cell-laden microgels.

Microfluidic principles have been extensively utilized as powerful tools to fabricate controlled monodisperse cell-laden hydrogel microdroplets for various biological applications, especially tissue engineering. In this review, we report recent advances in microfluidic-based droplet fabrication and provide our rationale to justify the superiority of microfluidics-based techniques over other microtechnology methods in achieving the encapsulation of cells within hydrogels. The three main components of such a system-hydrogels, cells, and device configurations-are examined thoroughly.
