This human heart-muscle patch can boost heart attack recovery

New York, Jan 13: Novel heart-muscle patches made with human cells can significantly improve recovery from a heart attack, results of a clinical trial show.

The results are a step closer to the goal of treating human heart attacks by suturing cardiac-muscle patches over an area of dead heart muscle in order to reduce the pathology that often leads to heart failure, said scientists led by Jianyi “Jay” Zhang, Chair of University of Alabama at Birmingham.

In the study, described in the journal Circulation, the team tested human cardiac-muscle patches of 1.57 by 0.79 inches in size and nearly as thick as a dime, created in the lab, on large animals in a heart attack model.

Transplanting two of these patches onto the infarcted area of a pig heart significantly improved function of the heart’s left ventricle, the major pumping chamber.

The patches also significantly reduced infarct size, which is the area of dead muscle, heart-muscle wall stress and heart-muscle enlargement, as well as significantly reducing apoptosis, or programmed cell death, in the scar boarder area around the dead heart muscle.

Furthermore, the patches did not induce arrhythmia in the hearts — improper beating of the heart, too fast or too slow.

Each patch was made from a mixture of three cell types — four million cardiomyocytes, or heart-muscle cells, two million endothelial cells — known to help cardiomyocytes survive and function in a micro-environment — and two million smooth muscle cells, which line blood vessels.

Each patch was grown in a three-dimensional fibrin matrix that was rocked back and forth for a week. The cells begin to beat synchronously after one day.

This mixture of three cell types and the dynamic rocking produced more heart muscle cells that were more mature, with superior heart-muscle physiological function and contractive force.

The patches resembled native heart-muscle tissue in their physiological and contractile properties, the scientists noted.

WHO’s Tedros says countries on “dangerous track” in pandemic

GENEVA : The world is now at a critical juncture in the COVID-19 pandemic and some countries are on a dangerous path, facing the prospect of health services collapsing under the strain, the head of the World Health Organization said on Friday.

“We are at a critical juncture in the COVID-19 pandemic, particularly in the Northern hemisphere,” WHO Director-General Tedros Adhanom Ghebreyesus told a news conference. “The next few months are going to be very tough and some countries are on a dangerous track.”

“We urge leaders to take immediate action, to prevent further unnecessary deaths, essential health services from collapsing and schools shutting again. As I said it in February and I’m repeating it today: This is not a drill.”

Tedros said too many countries were now seeing an exponential increase in infections, “and that is now leading to hospitals and intensive care units running close or above capacity — and we’re still only in October”.

He said countries should take action to limit the spread of the virus quickly. Improving testing, tracing of contacts of those infected and isolation of those at risk of spreading the virus would enable countries to avoid mandatory lockdowns.

New Delhi, Oct 22 : The Delhi High Court will, on November 4, hear a plea seeking direction to release the salaries and allowances of the nursing staff at the Rajan Babu Institute of Pulmonary Medicine and Tuberculosis, under the North Delhi Municipal Corporation, pending since June this year.

The matter was listed before a division bench of Chief Justice D.N. Patel and Justice Prateek Jalan on Wednesday but got adjourned as the bench didn’t assemble.

The petition, filed by the Delhi Nurses Union, also sought directions to release the nursing personnel staff’s arrears since January 2016 pertaining to the Central Pay Commission bonus, Dearness Allowance, Leave Travel Concession, etc.

The plea further states that nursing personnel have been presently collectively working vigorously in the detection of coronavirus as well by conducting home visits, virtual community meetings, contact tracing, organising Covid-19 tests, comorbidity evaluation, ensuring regular medication, defaulter patients visits, record maintenance, etc.

“The nursing personnel, in accordance with the service conditions, are lawfully entitled to regularly receive the monthly salary along with all the associated allowances and benefits,” the plea said.
