Article Synopsis
  • Since late 2020, new SARS-CoV-2 variants have frequently appeared, showing differences that may help them evade immunity from past infections.
  • The Early Detection group within the NIH's SARS-CoV-2 program utilizes bioinformatics to track these variants' emergence, spread, and traits, highlighting important ones for further study.
  • Since April 2021, this group has successfully prioritized variants each month, assisting NIH researchers by providing timely data on SARS-CoV-2 evolution for guiding experiments.

Article Synopsis
  • The emergence of new SARS-CoV-2 variants threatens the effectiveness of immunity from previous infections or vaccinations.
  • To tackle this issue, the NIH launched the SARS-CoV-2 Assessment of Viral Evolution (SAVE) program for real-time assessment of variant risks that might impact transmission and vaccine efficacy.
  • The program focuses on gathering and analyzing data on emerging variants and their effects on immunity, using animal models, while also addressing future challenges in monitoring rapidly evolving viruses.

A therapeutic vaccine that induces lasting control of HIV infection could eliminate the need for lifelong adherence to antiretroviral therapy. This study investigated a therapeutic DNA vaccine delivered with a single adjuvant or a novel combination of adjuvants to augment T cell immunity in the blood and gut-associated lymphoid tissue in SIV-infected rhesus macaques. Animals that received DNA vaccines expressing SIV proteins, combined with plasmids expressing adjuvants designed to increase peripheral and mucosal T cell responses, including the catalytic subunit of the E.

Objectives: To develop a suprapubic catheter (SPC) training model as no specific realistic training model exists to replicate SPC exchange where a catheter tract is present.

Materials And Methods: We describe a novel, anatomically realistic, animal simulator model for use in SPC training, which was trialed at a national urology simulation boot camp by new urology trainees and validated by expert urologists. A scale reproduction of an abdominal wall was created using a porcine abdominal wall.

Context: Bladder pain syndrome/interstitial cystitis (BPS/IC) is a poorly understood chronic debilitating condition. Surgery is reserved for severe refractory cases; however, there is no consensus on patient selection or optimal approach.

Objective: To evaluate the evidence relating to the safety and efficacy of surgical interventions for treating BPS/IC.
