A Call for Better, Not Faster, Research Ethics Committee Reviews in the Covid-19 Era.

With the rapid spread of SARS-CoV2 has come a rapid proliferation of clinical research studies, resulting in considerable strain on research ethics committees (RECS), which need to review study proposals. RECs are pressured to move through the review process quickly so that studies can get underway to address the pandemic. These committees are also asked to increase efficiency without relaxing the standards for ethical review.

Centralized Lung Nodule Management at A Veterans Hospital Using A Multidisciplinary Lung Nodule Evaluation Team (LNET).

Background: Lung nodules are frequently identified on imaging studies and can represent early lung cancers. We instituted the Lung Nodule Evaluation Team (LNET) to optimize management of these nodules by a lung specialist physician. All lung nodules identified by a radiologist prompted a direct consultation to this service.

Antitumor effect of secreted Flt3-ligand can act at distant tumor sites in a murine model of head and neck cancer.

The Flt3 ligand (Flt3-L) manifests antitumor activity, presumably due to its capacity to recruit dendritic cells and cause their proliferation. To assess whether local production of Flt3-L can mediate a "distant bystander" effect, murine B4B8 squamous cell carcinoma cells were transfected with a plasmid encoding a secretory form of Flt3-L to produce B4B8FL cells. Similarly, B4B8FL and B4B8 cells were transfected with herpes simplex virus thymidine kinase (HSVTK) to produce B4B8TK and B4B8FL/TK cells, which should be sensitive to ganciclovir (GCV), to know whether the effects of Flt3-L and HSVTK/GCV would be synergistic.
