Bridging the Gap: Developing a Palliative Approach to Care for Young Adults with Life Limiting Conditions

Bridging the Gap: Developing a Palliative Approach to Care for Young Adults with Life Limiting Conditions

More young adults (YAs) with life limiting conditions (LLC) are surviving into adulthood as earlier diagnosis and improved medical management in pediatric care lead to higher rates of survival for cancer, congenital heart and neuromuscular conditions. When these YAs leave pediatric care, they leave behind comprehensive and coordinated health, social and education services for uncoordinated adult systems, with limited access to palliative services they received in pediatric care.

YAs with LLCs will benefit from a public health palliative approach to care. This approach better matches their chronic disease trajectories of a series of declining plateaus over a period of months to years, punctuated by unpredictable periodic crises. Public health palliative care is a blended provision of health care and community services based on evidence that health care is most effective and least expensive when offered in conjunction with a complement of services that reflects social determinants of health and well-being. For YAs with LLCs, these resources will support their health, social, vocational, independent living, and educational goals to maximize their opportunities in an abbreviated time frame.


The objectives of this workshop are to:

1. Provide an overview of the young adult population with palliative care needs.
2. Discuss current care of this population.
3. Highlight results from three recent projects to examine and address needs of this population.
4. Dialogue with audience about other programs, initiatives, or ideas to address the needs of this population.

We look forward to robust conversations and ideas from your practice and research.

Insight into determinants of substrate binding and transport in a multidrug efflux protein

Multidrug resistance arising from the activity of integral membrane transporter proteins presents a global public health threat. In bacteria such as Escherichia coli, transporter proteins belonging to the major facilitator superfamily make a considerable contribution to multidrug resistance by catalysing efflux of myriad structurally and chemically different antimicrobial compounds. Despite their clinical relevance, questions pertaining to mechanistic details of how these promiscuous proteins function remain outstanding, and the role(s) played by individual amino acid residues in recognition, binding and subsequent transport of different antimicrobial substrates by multidrug efflux members of the major facilitator superfamily requires illumination. Using in silico homology modelling, molecular docking and mutagenesis studies in combination with substrate binding and transport assays, we identified several amino acid residues that play important roles in antimicrobial substrate recognition, binding and transport by Escherichia coli MdtM, a representative multidrug efflux protein of the major facilitator superfamily. Furthermore, our studies suggested that 'aromatic clamps' formed by tyrosine and phenylalanine residues located within the substrate binding pocket of MdtM may be important for antimicrobial substrate recognition and transport by the protein. Such 'clamps' may be a structurally and functionally important feature of all major facilitator multidrug efflux proteins.
