Seroprevalence of SARS-CoV-2 antibodies in healthcare workers at a London NHS Trust.

Healthcare workers (HCWs) have a theoretically increased risk of contracting severe acute respiratory coronavirus virus 2 (SARS-CoV-2) given their occupational exposure. We tested 2,167 HCWs in a London Acute Integrated Care Organisation for antibodies to SARS-CoV-2 in May and June 2020 to evaluate seroprevalence. We found a seropositivity rate of 31.

Randomized Controlled Trials to Define Viral Load Thresholds for Cytomegalovirus Pre-Emptive Therapy.

Background: To help decide when to start and when to stop pre-emptive therapy for cytomegalovirus infection, we conducted two open-label randomized controlled trials in renal, liver and bone marrow transplant recipients in a single centre where pre-emptive therapy is indicated if viraemia exceeds 3000 genomes/ml (2520 IU/ml) of whole blood.

Methods: Patients with two consecutive viraemia episodes each below 3000 genomes/ml were randomized to continue monitoring or to immediate treatment (Part A). A separate group of patients with viral load greater than 3000 genomes/ml was randomized to stop pre-emptive therapy when two consecutive levels less than 200 genomes/ml (168 IU/ml) or less than 3000 genomes/ml were obtained (Part B).

Chronic lung disease in HIV-infected children established on antiretroviral therapy.

Objective: Respiratory disease is a major cause of morbidity and mortality in HIV-infected children. Despite antiretroviral therapy (ART), children suffer chronic symptoms. We investigated symptom prevalence, lung function and exercise capacity among older children established on ART and an age-matched HIV-uninfected group.

Uptake and yield of HIV testing and counselling among children and adolescents in sub-Saharan Africa: a systematic review.

Introduction: In recent years children and adolescents have emerged as a priority for HIV prevention and care services. We conducted a systematic review to investigate the acceptability, yield and prevalence of HIV testing and counselling (HTC) strategies in children and adolescents (5 to 19 years) in sub-Saharan Africa.

Methods: An electronic search was conducted in MEDLINE, EMBASE, Global Health and conference abstract databases.

Influenza and pneumococcal vaccinations in dialysis patients in a London district general hospital.

Background: Patients on dialysis mount reduced immune responses compared with the general population. The Department of Health advises that these patients receive influenza and pneumococcal vaccinations at regular intervals-once yearly and every five years, respectively. This article investigates the uptake of these vaccinations in this patient population and seeks to examine factors that may influence vaccination status such as patient's language and presence of a general practitioner (GP) electronic vaccination reminder system.

Liver transplant for adult hemophagocytic lymphohistiocytosis: case report and literature review.

We report the case of a middle-aged man who died from multiorgan failure 3 weeks after orthotopic liver transplant for fulminant hepatic failure, associated with a rare, often fatal, hematologic condition that usually presents in childhood. We discuss the importance of its diagnosis, treatment, and implications for liver transplant.

Risk of transmission of H1N1 influenza by solid organ transplantation in the United Kingdom.

Background: Concern that pandemic H1N1 swine influenza could be transmitted by solid organ transplantation led to the publication of guidance advising screening of donors, restriction of use of organs under certain conditions, and prophylaxis of recipients. We have reviewed the outcomes for cases of solid organ graft recipients from H1N1 influenza-positive donors in the United Kingdom up to May 2010.

Methods: The Organ Donation and Transplantation Directorate supplied a list of five known H1N1 influenza-positive donors, one of whom died from active H1N1 infection.

Gonococcal peritonitis diagnosed post laparotomy in a 38-year-old woman: a case report.

A 38-year-old South African lady with a background history of cervical intra-epithelial neoplasia and recent colposcopy presented to the emergency department with severe abdominal pain. Initial investigations were non-diagnostic and despite empirical antibiotic therapy the patient developed peritonism. Post-laprotomy the diagnosis of severe pelvic inflammatory disease and peritonitis secondary to infection with Neisseria Gonorrhoea was made.
