File photo by Mike Dougherty/VTDigger [U]niversity of Vermont Medical Center is planning an $8.6 million expansion of its primary care services in Chittenden County, new state documents show. Amid a statewide shortage of adult primary care services, hospital administrators have proposed a new facility in Essex that could handle up to 10,500 additional patient visits annually. It would be twice the size of the hospital's current Essex practice and would add seven new staff. The practice also would include an in-house psychiatrist and a drug and alcohol counselor as part of a statewide and nationwide effort to integrate such services with medical care. "It's kind of one-stop shopping," said Dr. Jennifer Gilwee, division chief of general internal medicine and geriatrics. "It just makes it easier to access...

Understanding Immune Cell Recruitment Key to STI Vaccine Development - Technology Networks

-

In a study published in Nature Communications, researchers from King’s have shown how skin vaccination can generate protective CD8 T-cells that are recruited to the genital tissues and could be used as a vaccination strategy for sexually transmitted infections.

One of the challenges in developing vaccines for STIs, such as HIV or herpes simplex virus, is understanding how to attract specialised immune cells, called CD8 T-cells, to take up residence in the part of the body where the virus first enters. These cells need to be in place, armed and ready to provide an immediate protective immune defence, rather than waiting for immune cells in the blood to enter the tissues which takes time.

Before this study, it was thought that vaccines ideally needed to be delivered directly to the body surface (e.g. female genital tissue) where the infection might start, so that the immune system can generate these CD8 T-cells, travel back to the vaccination site and eliminate any future virus that is encountered. However, delivering vaccines directly to the female genital tissue is neither patient-friendly nor efficient.

Now the team from King’s have found that their vaccination strategy marshals a platoon of immune cells, called innate lymphoid cells (ILC1) and monocytes, in the genital tissues to work together and release chemicals (chemokines) to send out a call to the CD8 T-cells generated by the vaccine to troop into the genital tissue.

This research builds on the team’s earlier work to develop skin vaccination techniques using a dissolvable ‘microneedle’ vaccine patch that once placed against the skin dissolves and releases the vaccine without requiring a hypodermic needle injection and generates immune responses.

Lead author, Professor Linda Klavinskis from King’s said: “This study highlights how specialised groups of ‘innate’ immune cells in distant tissues can be harnessed to attract protective CD8 T-cells, arming the body’s frontline tissues from infection.

“We now need to confirm these results with other types of vaccines from the one used in the study to see if a common pathway is triggered by skin vaccination. If proven, this could have a significant impact in improving the  effectiveness of vaccines against sexually transmitted infections.”

advanced primary care of the ozarks :: Article Creator Integrating Rx With Advanced Primary Care Will Unlock Better Health America's healthcare industry has been squeezed tightly over the past few years with post-pandemic fallout, a declining economy and high consumer expectations. Retail pharmacies are no exception, and it's clear that the traditional pharmacy model is in crisis. With rising costs for medications and supplies and changing consumer retail habits, this doesn't bode well for the brick-and-mortar community pharmacy. Simply put: the traditional pharmacy model is unsustainable. We will soon see a rash of closing retail pharmacies and consumers scrambling to fill needed prescriptions affordably. You might be asking yourself why this should matter to you as HR and benefit professionals.
