Cone of light aims to cut pandemic fears by killing 99.9% of viruses with light
Far-UVC light could make sidewalks safer and plaza folks happy to gather again.

We’re all eager to look forward and imagine a time where vaccine-sated countries and states lift restrictions on the pandemic and we go on with our life . The question is, can we expect to shed our deep anxiety about that, too?
A new technology using light can help us in that regard.

In the Netherlands, a design team wants to restore confidence with a cone-of-light design. This is being referred to as a “floating design” installation that emits specific light that kills viruses.

A randomized double-blind controlled trial of convalescent plasma for adults hospitalized with severe COVID-19 found that mortality at 28 days in the treatment arm was half the rate seen in the control arm (12.6% vs. 24.6%), although treatment was not associated with other improvements in clinical status.
The study was led by investigators from the Center for Infection and Immunity at Columbia University Mailman School of Public Health; Columbia University Irving Medical Center; ICAP at Columbia University; Instituto Nacional de Infectologia and Hospital Federal dos Servidores do Estado in Rio de Janeiro, Brazil; University of Washington; and New York Blood Center. The results are published in the Journal of Clinical Investigation.

Blood pressure is controlled by many medications but in some people, they don t work as desired resulting in drug resistant hypertension and so they need additional therapeutic approaches to help patients get their blood pressure under control.
To overcome this issue, recently a study led by researchers at Columbia University Vagelos College of Physicians and Surgeons and New York-Presbyterian published in journal
The Lancet tests a clinical procedure called Renal denervation , that delivers two to three short blasts of ultrasound to nerve fibres that travel close to the renal artery.
The participants of the study were adults with moderate to severe hypertension despite taking three or more antihypertensive drugs, among them 69 were treated with renal denervation and 67 had the sham procedure.
Brief pulses of ultrasound delivered to nerves near the kidney lowered blood pressure in people with drug-resistant hypertension, Columbia and NewYork-Presbyterian physicians have found.

Ultrasound-based renal denervation (Paradise; ReCor Medical) significantly lowers systolic blood pressure when compared with a sham procedure in patients with resistant hypertension treated on a background of antihypertensive therapy, the RADIANCE-HTN TRIO shows.
Renal denervation reduced daytime ambulatory systolic blood pressure by 8.0 mm Hg compared with a 3.0-mm Hg reduction observed in patients treated with the sham procedure, a median between-group difference of 4.5 mm Hg (
P = 0.02). Additionally, there were significant between-group reductions in 24-hour ambulatory systolic blood pressure, nighttime ambulatory systolic blood pressure, and office- and home-based systolic blood pressure.
“I don’t want to be perceived as overselling anything, but sham-controlled controls are great for determining if there is an effect or not,” senior investigator Ajay Kirtane, MD (NewYork-Presbyterian/Columbia University Irving Medical Center, New York, NY), told TCT
