A Study to Evaluate Subcutaneous Daratumumab in Combination With Standard Multiple Myeloma Treatment Regimens

Sep 9th, 2022 - The hypothesis is that the addition of daratumumab administered SC to standard MM regimens will improve responses compared to response data observed in completed phase 3 studies without daratumumab. Disease evaluations will include measurements of myeloma proteins, bone marrow examinations, skeletal surveys, assessment of extramedullary plasmacytomas, and measurements of serum calcium corrected...

Rebound of SARS-CoV-2 Infection after Nirmatrelvir–Ritonavir Treatment
The New England Journal of Medicine; Charness ME, .

Sep 15th, 2022 - Nirmatrelvir is an inhibitor of the main protease in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has been shown to block viral replication and reduce disease severity in unvaccinated persons at risk for the progression of coronavirus disease 2019 (Covid-19).1 Here, we describe the occurrence of rebound symptoms and viral replication after treatment with nirmatrelvir combin...

How deadly is monkeypox? What scientists know
Nature Kozlov M.

Sep 13th, 2022 - The global monkeypox outbreak has caused some deaths, but the death rate is lower than expected from historical data — and scientists are breathing a cautious sigh of relief. Out of more than 57,000 people confirmed to have had monkeypox infections, at least 22 have died, representing a death rate of about 0.04%. That’s significantly less than the 1–3% that has been reported during outbreaks ca...

How nasal-spray vaccines could change the pandemic
Nature Waltz E.

Sep 6th, 2022 - Are sprays the future of COVID-19 vaccines? That’s the hope of dozens of research groups and companies working on new kinds of inoculation. Rather than relying on injections, these use sprays or drops administered through the nose or mouth that aim to improve protection against the virus SARS-CoV-2.

Evidence of human-to-dog transmission of monkeypox virus
The Lancet; Seang S, .

Aug 27th, 2022 - Human monkeypox virus is spreading in Europe and the USA among individuals who have not travelled to endemic areas.1 On July 23, 2022, monkeypox was declared a Public Health Emergency of International Concern by WHO Director-General Tedros Adhanom Ghebreyesus.2 Human-to-human transmission of monkeypox virus usually occurs through close contact with the lesions, body fluids, and respiratory drop...

COVID-19 Disease Severity in Persons Infected With Omicron BA.1 and BA.2 Sublineages and Association With Vaccination Status
JAMA Internal Medicine; Butt AA, Dargham SR et. al.

Aug 22nd, 2022 - Infection with the SARS-CoV-2 Omicron variant is associated with less severe disease compared with the Delta variant.1-3 Two main Omicron sublineages—BA.1 and BA.2—have variable geographic distribution. In Qatar, BA.1 was initially predominant but was quickly replaced by BA.2 as the predominant sublineage. This study sought to determine and compare the severity of SARS-CoV-2 infection among per...

Which COVID boosters to take and when: a guide for the perplexed
Nature Ledford H.

Aug 19th, 2022 - The next generation of COVID-19 vaccines is on its way, but those shots will be looking to take a seat at an already crowded table. On the menu in some countries this autumn will be the familiar standards — mRNA and protein vaccines based on the spike protein from the ancestral version of SARS-CoV-2, which ushered in the pandemic. Alongside them will be a smattering of new specials, includin...
