SARS-CoV-2 immunity and vaccine strategies in people with HIV.

Current severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccines, based on the ancestral Wuhan strain, were developed rapidly to meet the needs of a devastating global pandemic. People living with Human Immunodeficiency Virus (PLWH) have been designated as a priority group for SARS-CoV-2 vaccination in most regions and varying primary courses (two- or three-dose schedule) and additional boosters are recommended depending on current CD4+ T cell count and/or detectable HIV viraemia. From the current published data, licensed vaccines are safe for PLWH, and stimulate robust responses to vaccination in those well controlled on antiretroviral therapy and with high CD4+ T cell counts.

Attenuated humoral responses in HIV after SARS-CoV-2 vaccination linked to B cell defects and altered immune profiles.

We assessed a cohort of people living with human immunodeficiency virus (PLWH) (n = 110) and HIV negative controls (n = 64) after 1, 2 or 3 SARS-CoV-2 vaccine doses. At all timepoints, PLWH had significantly lower neutralizing antibody (nAb) titers than HIV-negative controls. We also observed a delayed development of neutralization in PLWH that was underpinned by a reduced frequency of spike-specific memory B cells (MBCs).

Attenuated humoral responses in HIV infection after SARS-CoV-2 vaccination are linked to global B cell defects and cellular immune profiles.

People living with HIV (PLWH) on suppressive antiretroviral therapy (ART) can have residual immune dysfunction and often display poorer responses to vaccination. We assessed in a cohort of PLWH (n=110) and HIV negative controls (n=64) the humoral and spike-specific B-cell responses following 1, 2 or 3 SARS-CoV-2 vaccine doses. PLWH had significantly lower neutralizing antibody (nAb) titers than HIV-negative controls at all studied timepoints.

A Springboard for physicians returning to practice.

Background: Many physicians take time out of training and have decreased confidence and poor performance ratings on their return. Courses employing multiple educational methods have been shown to be effective in easing learners into new clinical roles during transition periods but, to date, there is limited evidence for courses to support trainees returning to practice (RTP).

Methods: A 2-day course, named Springboard, was developed, specifically to address the needs of trainee physicians RTP.

Presentations and outcomes of central nervous system TB in a UK cohort: The high burden of neurological morbidity.

Objectives: Most data for Central Nervous System Tuberculosis (CNS-TB) derive from high-incidence, resource-limited countries. We sought to determine the presentation, management and outcomes of CNS-TB in a low-incidence setting with accessible healthcare.

Methods: We undertook a retrospective, observational study of CNS-TB in adults at a single tertiary-referral London hospital (2001-2017).

Evaluation of training programmes mapped to the new internal medicine curriculum.

In preparation for the internal medicine training (IMT) programme introduced in 2019, the core medical training (CMT) programme in London was made 'IMT-ready' in 2018 by creating new rotations that reflected the compulsory requirements of the first 2 years of the IMT curriculum, including provision of the requisite number of critical care placements. Core medical trainees completed posts within the 'IMT-ready' programme between August 2018 and August 2019, during which time the trainee experience was evaluated. A total of 497 responses were received.
