Study: Diminished COVID Vaccine Response in Lupus

Jan 30th, 2023 - Patients with systemic lupus erythematosus (SLE) showed reduced antibody responses following COVID-19 vaccination, with drugs for the condition such as belimumab (Benlysta) and mycophenolate mofetil (MMF) likely to blame, researchers said. Immunoglobulin G (IgG) titers measured 2 weeks after the second dose of mRNA COVID vaccines were lower by about 20% among 342 lupus patients compared with th...

Jan 30th, 2023 - The FDA has granted accelerated approval to pirtobrutinib (Jaypirca), a non-covalent or reversible Bruton's tyrosine kinase (BTK) inhibitor, for the treatment of relapsed or refractory mantle cell lymphoma (MCL) after at least two prior lines of systemic therapy, including a BTK inhibitor. Pirtobrutinib is the first BTK inhibitor of any kind specifically approved for patients with MCL that has ...

Viruses Tied to Subsequent Dementia, Other Neurodegenerative Diseases

Jan 30th, 2023 - At least 22 viral illnesses were linked with an increased risk of subsequent neurodegenerative disease, NIH researchers found. Using data from the U.K. and Finland, Mike Nalls, PhD, of the NIH Center for Alzheimer's and Related Dementias, and co-authors identified 45 viral exposures that were tied to an increased risk of dementia or other neurodegenerative diseases and replicated 22 of these as...

Lipid biomarkers that reflect postoperative recurrence risk in lung cancer patients who...
Lipids in Health and Disease; Takanashi Y, Kahyo T et. al.

Jan 29th, 2023 - The risk of postoperative recurrence is higher in lung cancer patients who smoke than non-smokers. However, objective evaluation of the postoperative recurrence risk is difficult using conventional pathological prognostic factors because of their lack of reproducibility. Consequently, novel objective biomarkers that reflect postoperative risk in lung cancer patients who smoke must be identified...

Patient-level performance evaluation of a smartphone-based malaria diagnostic application.
Malaria Journal; Yu H, Mohammed FO et. al.

Jan 29th, 2023 - Microscopic examination is commonly used for malaria diagnosis in the field. However, the lack of well-trained microscopists in malaria-endemic areas impacted the most by the disease is a severe problem. Besides, the examination process is time-consuming and prone to human error. Automated diagnostic systems based on machine learning offer great potential to overcome these problems. This study ...
