Discovery, Development & Delivery Of Safe, Effective & Affordable Vaccines For Global Public Health — Dr. Jerome H. Kim, M.D., Director General, International Vaccine Institute (IVI)

Dr. Jerome H. Kim, M.D., is the Director General of the International Vaccine Institute (IVI — https://www.ivi.int/), a nonprofit International Organization established in 1997 as an initiative of the United Nations Development Programme (UNDP), dedicated to the discovery, development and delivery of safe, effective and affordable vaccines for global public health.

IVI is headquartered in Seoul and hosted by the Republic of Korea with 36 member countries and the WHO on its treaty.

After months of shortages, pharmacies across the United States are being stocked with drugs to treat Covid-19. Now, the bottleneck has shifted to getting a prescription — and patients and public health agencies are looking to telehealth for help.

“Sometimes we hear telehealth is going to cure all of our challenges with access to health care, and that’s just not the case,” said Michelle Morse, chief medical officer of New York City’s department of health. “It’s a significant step forward in access, and yet there are still equity concerns with telehealth. It’s not a panacea.”

The patients most likely to know about and navigate digital health platforms to access the antivirals are typically younger, more affluent, and already well-served by the health system. And while a small group of public health departments are offering free telehealth, the end of the Health Resources and Services Administration Covid-19 Uninsured program means that uninsured patients may struggle to pay for teleservices, let alone any Covid care.

Michelle Lin, an emergency physician who works on an urgent care telehealth line in New York City, said many of the patients she sees turn to telehealth for Covid care have primary care doctors, but have struggled to get an appointment with them on short notice.

New technology could add another layer of protection against the next pandemic by simply turning on a light. Researchers are exploring a new way of using ultraviolet light to make indoor air safer.

“It’s been known for 80 years or so that ultraviolet light can kill bacteria and inactivate viruses in the air so that they’re no longer infectious,” Don K. Milton, professor of occupational and environmental health at the University of Maryland School of Public Health, told CBS News.

Conventional UV-C light has been used extensively in places like hospitals, homeless shelters and prisons. But that conventional UV light can damage the skin and eye, so should not be shined directly at people.

* Astrocytes play a variety of roles with neurons, but until now, scientists did not know that these cells carry electrical impulses.

* Applying new technology, Tufts University scientists recently discovered in mice that astrocytes are electrically active like neurons. Astrocytes play a variety of roles with neurons, but until now, scientists did not know that these cells carry electrical impulses.

Neurotransmitters are chemical messengers that facilitate the transfer of electrical signals between neurons and support the blood-brain barrier. Scientists have long understood that astrocytes control these substances to support neuronal health.

This study breaks ground in showing that neurons release potassium ions, which change the astrocytes’ electrical activity. This modulation affects how the astrocytes control neurotransmitters.

Researchers have identified distinct differences among the cells comprising a tissue in the retina that is vital to human visual perception. The scientists from the National Eye Institute (NEI) discovered five subpopulations of retinal pigment epithelium (RPE)—a layer of tissue that nourishes and supports the retina’s light-sensing photoreceptors. Using artificial intelligence, the researchers analyzed images of RPE at single-cell resolution to create a reference map that locates each subpopulation within the eye. A report on the research published in Proceedings of the National Academy of Sciences.

“These results provide a first-of-its-kind framework for understanding different RPE cell subpopulations and their vulnerability to retinal diseases, and for developing targeted therapies to treat them,” said Michael F. Chiang, M.D., director of the NEI, part of the National Institutes of Health.

“The findings will help us develop more precise cell and gene therapies for specific degenerative eye diseases,” said the study’s lead investigator, Kapil Bharti, Ph.D., who directs the NEI Ocular and Stem Cell Translational Research Section.

The BA.2 omicron subvariant still remains the dominant COVID strain across the U.S., but another subvariant has gained momentum in recent days.

BA.2.12.1, which health officials say appears to be up to 27% more contagious than BA.2, accounts for approximately 36.5% of cases nationwide, according to the most recent CDC weekly numbers.

While BA.2 accounts for approximately 75% of all cases in the country, it is said to make up at least 70% of the cases in the healthcare region encompassing New York, New Jersey, Puerto Rico and the Virgin Islands.

Not 6 million but 21 million.

And it has all happened because of a virus that caught the world unprepared.

The WHO report released today states that total deaths as reported by national health authorities attributable to COVID-19 don’t take into account excess mortality, or as it describes, “the mortality above what would be expected based on the non-crisis mortality rate.”

Excess mortality is not a measure that can easily be gleaned from across the planet. Why not? Because not all countries measure mortality at the same pace and in the same way. Data reporting techniques differ. Some countries don’t even measure at all. This makes calculating excess mortality problematic.

Tenet Healthcare Corporation recently experienced a cybersecurity incident in April 2022, which resulted in a temporary disruption to a subset of acute care operations.

The report from Tenet comes on the heels of telephone and computer problems occurring at St. Mary’s Medical Center and Good Samaritan Medical Center in West Palm Beach Florida, that were reported by WPTV NewsChannel 5. Tenet health is the parent company for both of the medical centers.

Patients and staff have contacted WPTV NewsChannel 5 expressing concerns about patient care tied to limits of electronic charting and their inability to communicate by telephone.
