56 percent of pregnant women in UK hospitals with COVID-19 are BAME

According to a new national surveillance study released this week, over half of the pregnant women admitted to a hospital in the United Kingdom with COVID-19 are either black or belong to other ethnic minority groups.

Synthetic monoclonal antibodies effectively neutralize SARS-CoV-2 in laboratory conditions

In a new study available on the preprint server bioRxiv*, a multinational research group demonstrated how monoclonal antibodies strongly inhibit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vitro at even sub-nanomolar concentrations. This makes them a prime candidate for the treatment of coronavirus disease (COVID-19).

Opioid, sedative and antidepressant use prior to surgery leads to more complications

A study led by University of Kentucky Markey Cancer Center researchers showed that patients who already used opioids, sedatives or antidepressants prior to colorectal surgery experience significantly more complications post-surgery.

Improving detection of SARS-CoV-2 infection among severely ill children

Researchers in the UK have conducted a study showing that children with a severe inflammatory syndrome had high levels of antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), despite having tested negative for the virus by polymerase chain reaction (PCR).

Irradiation with UV light kills SARS-CoV-2

Researchers in Italy have found that it is possible to completely inactivate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using short-wavelength UV (UV-C) irradiation.

Novel compound shows promise for ANCA-associated vasculitis

ANCA-associated vasculitis (AAV) is a systemic disease involving the formation of special autoantibodies (so-called anti-neutrophil cytoplasmic antibodies/ANCA) and vascular inflammation.

Researchers discover important molecular mechanism of Charcot-Marie-Tooth disease

Charcot-Marie-Tooth (CMT) disease is the most common form of inherited neuropathies. A genetic mutation causes the insulating myelin layer of peripheral nerves to become progressively damaged, resulting in severe disabilities in the case of CMT type 4B, for instance.

Study: Surfaces play a key role in viral transmission

Virus DNA left on a hospital bed rail was found in nearly half of all sites sampled across award within 10 hours and persisted for at least five days, according to a new study by UCL and Great Ormond Street Hospital (GOSH).

Monocytes could be critical in dysregulated immunity in COVID-19

A new study by Spanish researchers as part of the GEN-COVID Project, and published on the preprint server medRxiv* in June 2020, suggests that monocytes are primarily involved in triggering the hyperinflammatory immune response that may underlie severe COVID-19 infection.

The receptor binding domain of the SARS-CoV-2

With the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) across most of the world, scientists are working strenuously to find effective therapies or vaccines. Most strategies being worked on at present are targeting viral entry into the host cells, mainly through the interaction of the SARS-CoV-2 S protein with the angiotensin-converting enzyme 2 (ACE2) receptor.

Inhibition of coronavirus spike protein binding to ACE2

A novel coronavirus, CoV-19, and a later phenotype CoV-2 were identified as the primary cause for severe acute respiratory syndrome (SARS CoV-2). The spike (S) protein of CoV-2 is one target for the development of a vaccine to prevent the viral entry into human cells. The inhibition of the direct interaction between ACE2 and the S-protein could provides a suitable strategy to prevent the membrane fusion of CoV-2 and the viral entry into human cells. Using MD simulations, we investigate the assembly process of a Coronavirus Spike protein fragment, the hexapeptide YKYRYL on the ACE2 receptor and its inhibitzory effect on the aggregation and activation of the CoV-2 spike receptor protein at the same receptor protein.

SARS-CoV-2 invasion of central nervous system through olfactory tract

As the COVID-19 pandemic continues to claim lives throughout the world, the evidence is mounting that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affects the respiratory tract as well as the central nervous system. Now, a new study by German researchers published on the preprint server bioRxiv in June 2020 describes various neurological manifestations of COVID-19, as well as the underlying pathophysiology.

Tocilizumab in COVID-19 patients on mechanical ventilation

Now, a new study by researchers from the University of Michigan and published on the online preprint server medRxiv* in June 2020 shows that the cytokine inhibitor tocilizumab could have a favorable effect on survival in the most severely infected patients who require mechanical ventilation. This needs to be confirmed by clinical trials.

New strategy may facilitate development of multi-epitope peptide vaccine against SARS-CoV-2

By combining T and B lymphocyte analysis with manufacturability heuristic, researchers from the US and Germany proposed a set of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine peptides to use in subsequent animal studies and clinical trials. Their paper is currently available on the bioRxiv preprint server.

Zinc-finger antiviral protein makes SARS-CoV-2 highly susceptible to interferons

By looking into zinc-finger antiviral proteins (ZAP), a new study from Germany and the United Kingdom (UK) and available on the preprint server bioRxiv suggests that zoonotic transmission of a coronavirus with a specific genetic make-up facilitated the pandemic spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but also its sensitivity to interferons.

Approved drug could help dampen massive immune response associated with severe COVID-19

The drug acalabrutinib, FDA-approved for the treatment of several types of B cell cancers, improved the oxygenation levels and decreased molecular markers of inflammation in a majority of 19 patients hospitalized for the treatment of severe COVID-19, according to a new study by Mark Roschewski and colleagues.

Kidney impairment significantly higher among hospitalized COVID-19 patients

Germany was not hit as hard by the SARS-CoV-2 pandemic as many other European countries. The reason for this is that the wave of infection reached Germany later, that the authorities were warned by the situation in Italy and Spain and at an early stage ordered a lockdown and conducted extensive testing.
