How blocking iron drives the lung immune system to control infection

Although COVID-19 commands the headlines today, tuberculosis (TB) remains the biggest infection killer in the world and multiple drug resistant TB, which does not respond to regular antibiotics, continues to be a major threat to global health.

TB is caused by bacteria (Mycobacterium tuberculosis) that most often affect the lungs. Tuberculosis kills over 4,000 individuals daily throughout the world; while here in Ireland resistant and highly complex cases of TB continue to rise year after year, with cases numbering over 300 annually

Now, scientists at Trinity College Dublin and St James’s Hospital, Dublin have discovered how the iron chelator, DFX, which functions by attaching to iron, drives the immune system to deal with tuberculosis (TB).

Iron is crucial for daily human function but is also an essential element for the survival of viruses and bacteria. For some time, scientists have known that depriving infections of iron can limit bacterial burden and help improve patient outcomes.

Coronavirus: the truth against the myths

Some alarming news are being heard lately concerning a new virus outbreak from China: the ‘Coronavirus’. It is one of the main topics on the media and the internet, but not all information we receive is true. A lot of myths are being spread. These false ideas are only causing fear and anxiousness on people, so the truth must be known in order to calm this unnecessary nervousness. However, before that, let’s put things into context.

This is not the first time that humans face a health threat coming from a Coronavirus family member: in 2003, the SARS-CoV caused severe acute respiratory syndrome (SARS) and in 2012 the MERS-CoV provoked the Middle East Respiratory Syndrome (MERS). Now, a new coronavirus epidemic has been reported coming from Wuhan, China. The so called 2019-nCoV. Its transmission can be done between animals and humans, and from person to person. Infected people can present mild symptoms such as cough or fever. Severe expressions of the disease are also possible, such as pneumonia, kidney failure and even death. Since we previously did not know about this virus, no treatment nor vaccines are available.

So, what about the myths? It is said that the coronavirus can come in packages from China. However, the virus does not survive long on objects, so there is no need to worry about getting infected by this mean. It is completely safe to receive anything from China. It is also said that pets at home may spread the virus, but there is no evidence that this happens. This does not mean you do not have to wash your hands after contact with pets. It should always be done to prevent other potential infections, such as Salmonella.

How China is attempting to prevent a second wave of infections

With Chinese experts concluding coronavirus can’t be eradicated, the focus is on keeping infections to a manageable level to avoid catastrophic surges.

Beijing: As the first major country to emerge from coronavirus lockdowns, China is focused on avoiding a devastating second wave of infections as it returns to a semblance of pre-pandemic life.

Distanced school desks, compulsory face masks and tracking apps are being deployed from the financial hub of Shanghai to the frigid northern province of Heilongjiang. With Chinese experts concluding that the virus cannot be eradicated, government officials are focused on keeping infections to a manageable level to avoid catastrophic surges that overwhelm hospitals.

This balancing act between letting people return to normal life while keeping infections at a low level is one that governments around the world, including the hardest-hit nations like Italy and the U.S., will have to try to master. Even with tools that others don’t have — powerful state surveillance and control of people’s movements — China doesn’t have a full picture, nor any guarantee of success.

“All of which means that as China restarts its economic and social life, there are known unknowns that could viably lead to another outbreak,” said Nicholas Thomas, a professor specializing in public health at City University of Hong Kong.

Can air conditioning spread the coronavirus?

A study linking coronavirus transmission to an air-conditioning unit has highlighted a potential challenge for restaurants and other businesses as the US takes steps to reopen from pandemic lockdown.

Researchers in China conducted a limited study after an incident in January where one diner infected nine others at a restaurant in the city of Guangzhou.

“We conclude that in this outbreak, droplet transmission was prompted by air-conditioned ventilation. The key factor for infection was the direction of the airflow,” researchers from the Guangzhou Center for Disease Control and Prevention said. Their report will be published ​in the Centers for Disease Control and Prevention’s Emerging Infectious Diseases journal in July.

‘We’re worried people who are sick are not contacting us’; Coronavirus impact on Cork GP services

GENERAL PRACTICE has changed drastically in the wake of the Covid-19 pandemic, adapting for the safety of both patients and staff .

Face-to-face consultations and packed waiting rooms have been replaced with video assessments and phone calls, as GP practices across Cork and Ireland have met head-on the constraints brought forward by the global crisis.

But while the general practice has changed, Cork GP Dr Nick Flynn emphases that services are still very much there for patients during this difficult time.

“General practice is open for business, not business as usual, but open for all the usual business,” he said. 

“It’s so important that the public understand this and know that general practice is still there for them for the routine stuff during this difficult period.

“We’re worried that people who are sick are not contacting us.
