A new monoclonal antibody discovered and developed at the National Institutes of Health safely prevented malaria for up to 9 months in people who were exposed to the malaria parasite. The small clinical trial is the first to show an antibody capable of preventing malaria in people. A total of 25 participants received at least one dose of an antibody named CIS43LS, and four of them received a second dose. Among adults who had never had malaria infection or vaccination, CIS43LS prevented malaria.

Icotinib is a highly selective, first-generation EGFR tyrosine kinase inhibitor (TKI) approved in China as first-line monotherapy in patients with NSCLC with somatic EGFR mutations. Following complete resection of EGFR-mutant stage-II to -IIIA non-small-cell lung cancer (NSCLC), icotinib significantly improves disease-free survival and has fewer side effects than chemotherapy, according to interim results of a phase-3 trial underway in China.

Physicians wearing white coats were rated as significantly more experienced and professional than peers wearing casual attire. Regardless of their attire, however, female physicians were more likely to be judged as appearing less professional and were more likely to be misidentified as medical technicians, physician assistants, or nurses, found research published in JAMA Network Open.

A white coat with scrubs attire was most preferred for surgeons (mean preference index, 1.3), whereas a white coat with business attire was preferred for family physicians and dermatologists (mean preference indexes, 1.6 and 1.2, respectively; P < .001.

While casual attire, such as fleece or softshell jackets emblazoned with the names of the institution and wearer, has become more popular attire for physicians in recent years.

Correcting endothelial dysfunction in both human tissue and an elastase-induced murine model of emphysema shows promise in stopping and reversing the course of the disease, according to an international group of researchers.

EC loss and dysfunction were also hallmarks of emphysematous lungs harvested from the elastase-treated mice. The team found that intravenous delivery of healthy lung ECs from genetically identical mice reversed these phenotypes.

“We also found,” continued Dr. Racanelli, “that removing a specific molecule from the cells had a similar result.” In particular the researchers observe that “Leucine-rich a-2-glycoprotein- 1 (LRG1) was a driver of emphysema, and deletion of Lrg1 from endothelial cells rescued vascular rarefaction and alveolar regression.” LRG1 upregulation, they note ,”directly correlated with severity of the COPD phenotype.”

A case report describes a novel helmet device that generates a noninvasive oscillating magnetic field and that shrunk a glioblastoma tumor by about a third.

The patient had end-stage recurrent glioblastoma and had undergone all standard therapy options. He wore the device for 5 weeks but died from an unrelated injury, so the treatment period was cut short.

A brain scan showed a 31% reduction of contrast-enhanced tumor volume, and an autopsy of his brain confirmed the rapid response to the treatment.
