Saliva can be more effective for COVID testing: Study
New York, June 12, 2021 (IANS): The addition of a simple processing step to saliva samples before testing may improve Covid-19 detection rate, eliminate the challenges of nasopharyngeal testing and facilitate mass surveillance, researchers say.
The researchers, including Ravindra Kolhe from Augusta University in the US, found that an innovative protocol that processes saliva samples with a bead mill homogeniser before real-time PCR (RT-PCR) testing results in higher sensitivity compared to NPS samples.
“Saliva as a sample type for Covid-19 testing was a game-changer in our fight against the pandemic. It helped us with increased compliance from the population for testing along with decreased exposure risk to the healthcare workers during the collection process,” said lead investigator Kolhe.
The study, published in The Journal of Molecular Diagnostics, included samples from a hospital and nursing home as well as from a drive-through testing site.
In the first phase (protocol U), 240 matched NPS and saliva sample pairs were tested prospectively for SARS-CoV-2 RNA by RT-PCR.
In the second phase of the study (SalivaAll), 189 matched pairs, including 85 that had been previously evaluated with protocol U, were processed in an Omni bead mill homogeniser before RT-PCR testing.
An additional study was conducted with samples with both protocol U and SalivaAll to determine if bead homogenisation would affect the clinical sensitivity in NPS samples.
Finally, a five-sample pooling strategy was evaluated. Twenty positive pools containing one positive and four negative samples were processed with the Omni bead homogeniser before pooling for SARS-CoV-2 RT-PCR testing and compared to controls.
In Phase I, 28.3 per cent of samples tested positive for SARS-CoV-2 from either NPS, saliva, or both. The detection rate was lower in saliva compared to NPS (50.0 per cent vs. 89.7 per cent).
In Phase II, 50.2 per cent of samples tested positive for SARS-CoV-2 from either saliva, NPS, or both.
The detection rate was higher in saliva compared to NPS samples (97.8 per cent vs. 78.9 per cent). Of the 85 saliva samples tested with both protocols, the detection rate was 100 per cent for samples tested with SalivaAll and 36.7 per cent with protocol U.
The U.S. Embassy in Colombo welcomed the U.S. Sports Envoys to Sri Lanka, former National Basketball Association (NBA) and Women’s National Basketball Association (WNBA) players Stephen Howard and Astou Ndiaye, from June 8 through 14.
The Public Diplomacy section of the U.S. Embassy said that it would launch a weeklong basketball program intended to harness the unifying power of sports, made possible through collaboration with Foundation of Goodness and IImpact Hoop Lab.
While in Sri Lanka, Howard and Ndiaye, both retired professional basketball players, will conduct a weeklong program, Hoops for Hope: Bridging Borders through Basketball. The Sports Envoys will lead basketball clinics and exhibition matches and engage in leadership sessions in Colombo and Southern Province for youth aged 14-18 from Northern, Uva, Eastern and Western Provinces, offering skills and leadership training both on and off the court. The U.S. Envoys will also share their expertise with the Sri Lanka Basketball Federation, national coaches, and players, furthering the development of basketball in the country. Beyond the clinics, they will collaborate with Sri Lankan schoolchildren to take part in a community service project in the Colombo area.
“We are so proud to welcome Stephen and Astou as our Sports Envoys to Sri Lanka, to build on the strong people-to-people connections between the United States and Sri Lanka,” said U.S. Ambassador Julie Chung. “The lessons that will be shared by our Sports Envoys – communication, teamwork, resilience, inclusion, and conflict resolution – are essential for leadership development, community building, equality, and peace. The U.S. Sports Envoy program is a testament to our belief that sports can be a powerful tool in promoting peace and unity.”
SJB Colombo District MP Mujibur Rahuman in parliament demanded to know from the government the reasons for CEB suspending the leave of all its employees until further notice from Thursday.
MP Rahuman said that the CEB has got an acting General Manager anew and the latter yesterday morning issued a circular suspending leave of all CEB employees with immediate effect until further notice.
“We demand that Minister Kanchana Wijesekera should explain this to the House. This circular was issued while this debate on the new Electricity Amendment Bill was pending. There are many who oppose this Bill. The Minister must tell parliament the reason for the urge to cancel the leave of CEB employees,” the MP said.However, Speaker Mahinda Yapa Abeywardena prevented Minister Wijesekera responding to the query and said that the matter raised by MP Rahuman was not relevant.
The Chartered Institute of Personnel Management (CIPM) successfully concluded the 8th Annual CIPM Symposium, which took place on 31st May 2024.

Since its inception in 1959, CIPM has been dedicated to advancing the HR profession through education, professional development, and advocacy, solidifying its position as Sri Lanka’s leading professional body for HRM.
Ken Vijayakumar, the President of the CIPM, graced the occasion as the chief guest. The symposium commenced with the welcome address by the Chairperson, Prof. Arosha Adikaram, followed by the Web Launch of the Symposium Proceedings and Abstract Book by the CIPM President. The event featured distinguished addresses, including a speech by Chief Guest Ken Vijayakumar, President of CIPM, and an address by Guest of Honor Shakthi Ranatunga, Chief Operating Officer of MAS Holdings Pvt. Ltd., Sri Lanka.
The symposium also featured an inspiring keynote address by Prof. Mario Fernando, Professor of Management and Director of the Centre for Cross Cultural Management (CCCM) at the University of Wollongong, Australia.

These included Cultural Diversity and Inclusion, Talent Development and Retention, Ethical Leadership and Corporate Social Responsibility, Adapting to Technological Advancements, Mental Health and Well-being at Work, Global Workforce Challenges, Employee Empowerment, and Reskilling and Upskilling.
The plenary session was led by Prof. Wasantha Rajapakse. Certificates were awarded to the best paper presenters during the valedictory session, followed by a vote of thanks delivered by Kamani Perera, Manager of Research and Development.
The annual symposium of CIPM was a truly inclusive event, attracting a diverse audience that spanned undergraduates, graduates, working professionals, research scholars and lecturers. This widespread interest highlights the symposium’s significance in the field of HRM, offering a unique opportunity for everyone to network and learn from scholarly brains.The CIPM International Research Symposium was sponsored by Hambantota International Port, Sri Lanka Institute of Information Technology (SLIIT), E B Creasy & Co. PLC, and Print Xcel Company.
