Little risk from dental aerosol procedures: 10 minutes gap is enough between two procedures

September 12, 2020 | News

We summarize all the latest pieces of evidence on dental aerosol procedures. We also trace the evidence back to 2003 SARS times when the aerosols were studied first. Despite weak evidence, dental aerosol-generating procedures have been termed risky.

First clinical trial: Vitamin D prevents Covid-19 complications in hospitalized patients

September 7, 2020 | News

A lot has been written on the role of vitamin D in the prevention & management of SARS-CoV-2 infection & COVID-19 disease. Interest in Vitamin D therapy has increased multifold after the recent bradykinin hypothesis successfully answered the questions that had been left unanswered by the cytokine storm hypothesis. The bradykinin hypothesis also proposed that Vitamin D therapy may control the bradykinin storm. However, the literature lacked a clinical trial in this regard. This article covers the results of a preliminary trial that has shown promising results with Vitamin D therapy in preventing complications in hospitalized Covid-19 patients.

‘Mask Mouth’- a novel threat to oral health in the COVID era – Dr Pooja Muley

August 26, 2020 | News

Today the use of face masks has become necessary and ubiquitous due to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Even though a face mask protects the user from SARS-CoV-2 infection, it has certain adverse effects. One of the new and recently noticed side effect is on the oral health of the wearer known as ‘Mask Mouth’. This includes symptoms like caries, gingivitis, halitosis, candidiasis and angular cheilitis. But a positive aspect of the mask-mouth is that it can be easily prevented and treated. In this article, we will see this new phenomenon, its aetiology, symptoms and prevention.

Cycle Threshold (Ct) value of RT-PCR can tell us if a SARS-CoV-2 infected person can spread disease

August 24, 2020 | News

Currently, all SARS-CoV-2 detection measures make use of RT-PCR test, and its results are generally reported as either positive or negative, which tells us if a person is infected. However, to contain the pandemic, what we need to know is whether that person is infectious or in other words, 'can he spread the disease?' It's important to know that the RT-PCR test does provide an additional measure of the viral load in the sample. This reading is called the cycle threshold (Ct) value. Evidence suggests that reporting this Ct value (calculated viral load) can assist in a better interpretation of the condition, and also in taking clinical decisions.

Humans develop robust immune response & memory that may provide lasting protection against Covid-19

August 21, 2020 | News

One of the most critical questions the world is waiting for an answer is if the human body can mount a protective response that provides a lasting immunity against SARS-CoV-2. This understanding is crucial to the success of vaccines, the successful return of recovered patients to their pre-pandemic lifestyle, and also, how readily the world can overcome the fear of pandemic spread.

Studies on mutations show SARS-CoV-2 has become more transmissible but less deadly

August 19, 2020 | News

Recently all mainstream media houses screamed: "Malaysia Detects New Coronavirus Strain 'D614G' Which is 'Ten Times' Deadlier." and the fear-mongering strategy tried to scare people with a question: "Worse to come?". This article analyses two mutations - D614G and Δ382. The evidence shows that the infection is only getting milder and less deadly. We present clinical, immunological, genomic and evolutionary perspectives.

First direct evidence: SARS-CoV-2 neutralizing antibodies protect against re-infection in humans

August 18, 2020 | News

Vaccine development against SARS-CoV-2 would be greatly facilitated by the identification of immunological parameters that correlate with protection in humans. However, to date, most studies on protective immunity have only been performed in animal models and correlates of protection have not been established in humans. This study provides the first direct evidence that SARS-CoV-2 neutralizing antibodies protect against SARS-CoV-2 re-infection in humans.

ORF8 & ORF3b antibodies: Accurate serological markers of early & late SARS-CoV-2 infection

August 18, 2020 | News

The currently available SARS-CoV-2 antibody tests with their traditional serological approaches just tell us - yes or no, which has resulted in an underestimation of asymptomatic and mild infections. The next-generation serologic tests with a broader landscape of antibody responses to a wide range of viral proteins may help us establish the timing of infections too. This editorial describes a recent study (Nature, 17th Aug 2020) that gives an idea about the future of antibody testing in Covid-19.

New Book: “B cell Immunotherapy in Oral Cancer: A Short Review” by Drs. Smitha T & Anela Thomas

August 12, 2020 | News

Immunotherapy is once again an emerging trend in cancer therapeutics, as an effective measure to reduce the mortality & morbidity rates. Evidence is evolving at a faster rate on the potential role of immunotherapy in the complete recovery from a tumour and its possible recurrence. T cell-based immunotherapy has been recognized for its role in curbing the tumour progression rate. However, the role of B cells is still controversial. This new book by Dr Smitha T & Anela Thomas explores the pro-tumourigenic & anti-tumorigenic roles of B lymphocytes in a tumour microenvironment.
