Digital tech could unlock warning signs for imminent sudden cardiac arrest

Posted by in categories: health, privacy

A new study in Lancet Digital Health identifies early warning symptoms like chest pain and dyspnea that are moderately associated with imminent sudden cardiac arrest. The research suggests that future digital technologies could combine these symptoms with biometric data to more precisely predict and potentially prevent these life-threatening events.

New Covid vaccines from Pfizer, Moderna and Novavax will likely protect against Eris variant

Posted by in categories: biotech/medical, health

The drugmakers designed their updated vaccines to target the omicron subvariant XBB.1.5, which is slowly declining nationwide. But health experts and initial data suggest that the new shots will still be effective against Eris, or EG.5, and other widely circulating variants – all of which are descendants of omicron.

“I think that these vaccines will provide very substantial protection against EG.5. Maybe just a little bit of loss, but it’s nothing that I’m very concerned about,” Dr. Mark Mulligan, director of the NYU Langone Vaccine Center, told CNBC. “It looks like we’re going to be OK.”

All three companies are still waiting for the Food and Drug Administration to approve their vaccines, meaning those jabs won’t be available to the public for a month or so. The Centers for Disease Control and Prevention also has to decide which Americans should get the shots and how often.

Biological clocks: How does the body know that time goes by?

Posted by in categories: biotech/medical, health

In April of this year, Spanish athlete Beatriz Flamini emerged into the light after a 500-day stay in a cave. Her descent underground is probably the longest undertaken by a long stretch. Flamini says she lost all sense of time on the 65th day. But can she really be sure it was the 65th day? By way of comparison, in 1962 France’s Michel Siffre surfaced from the Scarasson chasm in Italy after spending what he thought was 33 days there. In fact, he spent 58 days underground.

How can isolated human beings keep regular track of time, even when they’re disconnected from their surrounding environment? Quite simply, because biological rhythms are at the heart of life, regulating it all the way from the up to that of the entire body. These include not only our sleep/, but also body temperature, hormones, metabolism and the cardiovascular system, to name but a few.

And these rhythms have many repercussions, not least in terms of public health. Indeed, a number of diseases are episodic—for example, asthma is more severe at night, while cardiovascular accidents are more frequent in the morning. Another example is shift work, which disconnects people from their environment. It may be associated with an increased risk of cancers in workers, prompting the WHO to label it as a probable carcinogen.

Scientists develop finger sweat test to detect antipsychotic drugs in patients

Posted by in categories: biotech/medical, health

Antipsychotic drugs treat incredibly vulnerable patients. Maintaining a treatment regimen is difficult for many patients, but not taking the medication is associated with a higher risk of poor health outcomes. These drugs are also very powerful with strong side effects, and blood tests are often used to calibrate a patient’s dosage and confirm that they are taking the recommended dose.

However, blood tests are invasive and potentially uncomfortable. Scientists have now discovered a way to test the levels of common in the sweat from patients’ fingerprints, offering a quicker, more comfortable, and more convenient alternative to blood draws for patient monitoring.

“Our test offers patients a quick and dignified way of showing commitment to antipsychotic treatment,” said Katherine Longman of the University of Surrey, first author of the study in Frontiers in Chemistry. “This non-invasive approach can also be adapted to fit other therapeutic regimes.”

Eye drop recall grows after FDA warning, reports of ‘adverse events’

Posted by in category: health

(WJW) – A nationwide recall of tainted eye drops is growing after bacterial and fungal contamination were found in sample tests, according to the Food and Drug Administration (FDA).

Dr. Berne’s Whole Health Products is now voluntarily recalling all lots of the company’s MSM Drops 5% Solution, 15% Solution, Organic Castor Oil Eye Drops and MSM Mist 15% Solution.

IBM makes major leap in quantum computing error-detection

Posted by in categories: biotech/medical, health, quantum physics, robotics/AI, space travel

Quantum computing is on the verge of catapulting the digital revolution to new heights.

Turbocharged processing holds the promise of instantaneously diagnosing health ailments and providing rapid development of new medicines; greatly speeding up response time in AI systems for such time-sensitive operations as autonomous driving and space travel; optimizing traffic control in congested cities; helping aircraft better navigate extreme turbulence; speeding up weather forecasting that better prepares localities facing potential disaster, and optimizing supply chain systems for more efficient delivery times and cost savings.

But we’re not there yet. One of the greatest obstacles facing quantum operations is error-correction.

England to roll out world’s first seven-minute cancer treatment jab

Posted by in categories: biotech/medical, health

Britain’s state-run national health service will be the first in the world to offer an injection that treats cancer to hundreds of patients in England which could cut treatment times by up to three quarters.

Following approval from the Medicines and Healthcare products Regulatory Agency (MHRA), NHS England said on Tuesday (Aug 29) hundreds of eligible patients treated with the immunotherapy, atezolizumab, were set to have “under the skin” injection, which will free up more time for cancer teams.

“This approval will not only allow us to deliver convenient and faster care for our patients, but will enable our teams to treat more patients throughout the day,” Dr Alexander Martin, a consultant oncologist at West Suffolk NHS Foundation Trust said.

A universal influenza vaccine

Posted by in categories: biotech/medical, health

The article titled “Evaluation of OVX836: A Promising Universal Influenza Vaccine Candidate” published in The Lancet presents a comprehensive assessment of OVX836, a novel influenza vaccine candidate targeting the nucleoprotein of influenza A virus. Authored by a team of researchers led by IL-R at CEVAC Clinical Unit and Laboratory, the study aims to investigate the safety, immunogenicity, and potential efficacy of OVX836 at different doses, shedding light on its potential as a universal influenza vaccine.

Influenza remains a significant global health concern, with seasonal epidemics and occasional pandemics causing substantial morbidity and mortality. Current influenza vaccines primarily focus on the viral surface protein hemagglutinin, but their efficacy is limited by antigenic variation and the emergence of new strains. Current vaccines are developed for the season based on what strains were prominent in the last season. Additionally, vaccine efficacies can vary from season to season. OVX836 takes a different approach by targeting the highly conserved nucleoprotein, which plays a crucial role in the influenza virus life cycle.

OVX836 elicited a robust immune response, characterized by significant increases in nucleoprotein-specific CD4 and CD8 T-cell responses, as well as the production of anti-nucleoprotein IgG antibodies. The magnitude of these immune responses displayed a dose-dependent relationship, with higher doses of OVX836 leading to stronger immune reactions. Of particular interest was the induction of a CD8 T-cell response, a rare achievement for influenza vaccines and a crucial component of comprehensive immune protection.

Protein inhibition could offer new strategies for treating severe asthma

Posted by in categories: biotech/medical, health

Inhibiting a protein on the surface of immune cells could offer new strategies for treating severe asthma, Cleveland Clinic researchers found.

Researchers discovered a new way a protein called MCEMP1 contributes to severe inflammation in the airway and lungs. The discovery, published in Nature Communications, provides critical information for developing therapeutic interventions to treat long-term lung conditions, including asthma, on a biological level.

The study was conducted in a lab led by Jae Jung, PhD, chair of the Cancer Biology Department, director of the Infection Biology program, and director of the Sheikha Fatima bint Mubarak Global Center for Pathogen & Human Health Research.
