Remdesivir no COVID-19 silver bullet

Published

on

An advisory body of the UN health agency is not recommending the use of the high-profile antiviral drug Remdesivir for hospitalized COVID-19 patients, saying on Thursday there is insufficient evidence that it improves survival outcomes or cuts down on the need for patients to be put onto ventilators. 

A World Health Organization (WHO) Guideline Development Group (GDG) panel of international experts made the recommendation in the BMJ – the weekly peer-reviewed medical journal, published by the British Medical Association – as part of so-called “living guidelines” to manage the coronavirus and help doctors make better decisions in consultation with patients. 

“Living guidelines are useful in fast moving research areas like COVID-19 because they allow researchers to update previously vetted and peer reviewed evidence summaries as new information becomes available”, said WHO, in a press release on the findings. 

Evidence-based decisions  

Remdesivir has received global attention in treating severe coronavirus cases and is increasingly being used for hospitalized patients. But its role in clinical practice has remained uncertain. 

WHO’s recommendation is based on new evidence comparing the effects of several drugs on treating the virus and includes data from four international randomized trials involving more than 7,000 COVID-19 inpatients. 

After reviewing the evidence, the WHO GDG expert panel, which includes four patients who have had the coronavirus, concluded that the intravenously administered Remdesivir “has no meaningful effect on mortality or on other important outcomes for patients, such as the need for mechanical ventilation or time to clinical improvement”. 

Arguing its use 

The panel acknowledged that the certainty of the evidence is low and did not prove that Remdesivir has no benefit; but rather, “there is no evidence based on currently available data that it does improve important patient outcomes”, according to the WHO release. 

However, the GDG supported the continued enrolment of patients into Remdesivir evaluation trials to determine whether more substantial evidence can be obtained, especially with regards to specific groups of patients.  

The WHO press release also cites a feature article linked in the panel’s BMJ report, which says that the full story of Remdesivir will not be understood until its manufacturer, Gilead, releases full clinical study reports. 

In the meantime, reports the journalist who wrote the feature, Jeremy Hsu, alternative treatments such as widely available corticosteroid, dexamethasone, that has been proved to reduce mortality among some severely-ill COVID-19 sufferers, are “now impacting discussions about Remdesivir’s cost-effectiveness”, in the words of the WHO press release.

Today marks the beginning of the first trials for the delivery of MMR, influenza and COVID-19 vaccines in the southern state of Telangana.

The trials, which have been organized by the World Economic Forum in partnership with the state government of Telangana, Apollo Hospital’s HealthNet Global and NITI Aayog, will be conducted over 28 days in designated air corridors in the district of Vikarabad, Telangana.

Starting off with the first ever drone delivery of a vaccine in India, the trials are focused on laying the groundwork for a more elaborate drone delivery network that will improve access to vital healthcare supplies for remote and vulnerable communities. This is also the first drone programme since India recently liberalized its drone policy.

“The Forum is pleased to support Indian government and industry in demonstrating how emerging technologies can be used to improve access to healthcare for its most vulnerable populations,” says Timothy Reuter, Head of Aerospace and Drones, World Economic Forum. “The project has set into motion the adoption of drones to deliver lifesaving services across the country. We believe that India’s work with drones can serve as a model for other countries in the region and beyond.”

“Ever since Telangana issued the expression of interest in expanded drone use in March 2020, the industry has witnessed an acceleration around policy decisions,” said Vignesh Santhanam, Lead, Aerospace and Drones, World Economic Forum. “With the latest liberalization of India’s drone economy the Medicine from the Sky initiative has made efforts to invigorate the drone sector in India by demonstrating the essence of cooperative federalism and creating a template for the region.”

“Being at the forefront of leveraging emerging technologies, Telangana has always acted as a testbed for innovative solutions to support scaling across the nation,” said K.T. Rama Rao, Minister of Information Technology, Industries, Municipal Administration and Urban Development of Telangana, India. “The COVID-19 pandemic has highlighted that healthcare supply chains can be further strengthened and drones offer a robust value proposition especially when it comes to remote areas and emergencies. The Medicine from the Sky is the first of its kind initiative in the country to generate insights that shall benefit the entire ecosystem. The enthusiasm and support by all the partners is deeply appreciated.”

With the support of the Vikarabad municipality, India’s Ministry of Civil Aviation, the Directorate-General of Civil Aviation and the Airports Authority of India, this will be the first drone-delivered COVID-19 vaccine in Asia. After extended trials with MMR and influenza vaccines, COVID-19 vaccines will also be transported beyond the visual line of sight.

“This pilot has been enabled through a series of collaborations between India’s regulatory agencies state government, the World Economic Forum, international organizations, healthcare experts and drone companies,” said Anna Roy, Senior Adviser, Frontier Technologies, NITI Aayog, Government of India. “The Medicine from the Sky community has acted as an important platform providing advice and insight that has translated the extensive academic groundwork into action on ground. Through a highly collaborative effort, the pilot programme also demonstrates the importance of localized inputs and micro planning for healthcare in remote parts of the world.”

This initiative aims to improve equity in healthcare while enabling healthcare access for isolated populations and hazard-prone areas. The project has eight participating partners, including drone operators and experts in healthcare and airspace management among others. Together, these partners will demonstrate short and long-range drone-based deliveries to assess the efficacy of low-altitude aerial logistics in healthcare.

“Drone use provides the opportunity to support our traditional approaches to healthcare delivery especially in underserved or remote regions of the country,” said Dr. Sangita Reddy, Joint Managing Director, Apollo Hospitals Group. “Our healthcare sector could potentially witness large-scale deliveries of long-tail medicines, vaccines, blood and vital organs throughout the country across terrains with drones in action. As clinical partners in the Medicine from the Sky initiative, Apollo Hospital’s HealthNet Global will be responsible for enabling vaccine and medicine availability and properly monitoring the adherence of clinical protocols throughout the project.”

An industry core group was commissioned in June 2021 to help scale the effort to bolster last-mile mobility in healthcare. The outcomes from the trials will be analysed and used to scale up the effort to additional states with the support of the Medicine from the Sky community and key stakeholders. The project is expected to be expanded to six states in the coming months.

Pandemic increasing risk factors for suicide

Published

on

Suicide prevention must be prioritized after 18 months of the COVID-19 pandemic, the Americas office of the World Health Organization (WHO) warned ahead of World Suicide Prevention Day, commemorated annually on 10 September. 

Studies show that the global crisis has exacerbated risk factors associated with suicidal behaviours, such as job loss, trauma or abuse, mental health disorders and barriers to accessing health care.

‘Urgent public health problem’ 

“Suicide is an urgent public health problem and its prevention must be a national priority,” said Renato Oliveira e Souza, head of the Mental Health Unit at the Pan American Health Organization (PAHO).  

“We need concrete action from all elements of society to put an end to these deaths, and for governments to create and invest in a comprehensive national strategy to improve suicide prevention and care,” he added. 

Globally, one in 100 deaths is by suicide, making it among the leading causes of death worldwide and the fourth leading cause of death among 15- to 29-year-olds, after road traffic accidents, tuberculosis and interpersonal violence. 

More people die each year from suicide than from HIV, malaria, or breast cancer, or from war and homicide, according to WHO

Warning signs 

Some of the verbal or behavioural warning signs for suicide include talking about wanting to die, feeling immense guilt or shame, or feeling like a burden to others.  Other signs are feeling empty, hopeless or trapped, or having no reason to live, or feeling extremely sad, anxious, agitated, or full of anger. 

Among behavioural changes that can also be warning signs, are researching ways to die, staying away from friends, giving away important items, showing extreme mood swings, eating or sleeping too much or too little, and using drugs or alcohol more often. 

Anyone who detects warning signs of suicide, whether in themselves or in someone they know, should seek help from a health care professional as soon as possible. 

Hope through action 

World Suicide Prevention Day is organized by the International Association for Suicide Prevention (IASP) and endorsed by WHO.  

This year’s theme ‘Creating hope through action’, focuses on the need for collective action to address the issue. 

WHO recently published guidance that supports national efforts to help reduce the global suicide rate by one-third by 2030, in line with the Sustainable Development Goals (SDGs). 

Key prevention measures include limiting access to means of suicide, such as firearms and pesticide, as well as early identification, assessment, management and follow-up of people affected by suicidal thoughts and behaviours. 

Other actions include fostering adolescent social-emotional skills, and educating the media in responsible reporting on suicide

Majority Want to Prioritize Equitable Access to COVID-19 Vaccines Before Boosters

Published

on

A new survey found a majority of fully vaccinated adults would get a COVID-19 vaccine booster shot if offered, but think priority should be given to people who have not yet had a first dose.

The latest World Economic Forum/Ipsos survey was conducted at the end of August in 13 countries and included 9,521 adults under the age of 75, of whom nearly 6,000 had received two doses of a COVID-19 vaccine.

The World Health Organization has called for a pause on COVID-19 vaccine boosters to narrow the gap in vaccinations between countries.

Genya Dana, Head, Health & Healthcare at the World Economic Forum said: “It is vital we work to close the gap between those with access to vaccines and those without. COVID-19 highlighted how vaccination is by far the most effective public health intervention to protect populations from disease and it is crucial that robust vaccination infrastructure is deployed in every country on earth.

Dr Dana continued: “At least 60% of world’s population needs to be vaccinated by 2022 to get the current pandemic under control – but the issue of equity and access must be front and centre of this effort. With only 0.4% of current doses administered in low-income countries, this crisis will keep multiplying. We need to redouble our efforts to get vaccines to everyone who hasn’t had one yet.”

Boosters likely needed

The survey shows a widespread belief that COVID-19 vaccine booster shots will be needed at least annually to maintain protection against the disease. The expectation was highest in Mexico, Brazil and the United Kingdom, but lowest in Russia.

The survey also showed that a majority of adults who have had two doses of the COVID-19 vaccine would get a booster shot if they were offered. Intent to get a booster shot was highest in Brazil (96%), Mexico (93%) and China (90%) and lowest in Russia (62%) and Italy (66%).
