Severe burns are a major component of conflict-related injuries and can result in high rates of mortality. Conflict and disaster-related severe burn injuries present unique challenges in logistic, diagnostic and treatment options, while wider conflict is associated with driving local antimicrobial resistance. We present a targeted review of available literature over the last 10 years on the use of systemic antimicrobial antibiotics in this setting and, given limited available data, provide an expert consensus discussion.

We investigated the dynamics of COVID-19 contacts subsequent conversion to SARS-CoV-2 infection in an inpatient setting across three National Health Service (NHS) Trusts. 9.2% (476/5,156) COVID-19 contacts met inclusion criteria, were typable and tested positive for COVID-19.

Article Synopsis
  • The study aimed to evaluate how national antimicrobial susceptibility data varies across different surveillance platforms, focusing on their usability and data completeness.
  • Researchers compared data from WHO, ECDC, and Pfizer databases, examining susceptibility in common blood isolate species using various statistical methods.
  • Findings revealed significant discrepancies in data reporting and agreement levels between the platforms, indicating that variability in surveillance data can weaken the effectiveness of antimicrobial resistance strategies globally.

Background: Intracranial abscesses are rare but serious, and are associated with significant morbidity and mortality. Due to both the rarity and severity of these infections, well-controlled trials have not been reported in the literature, and optimal management is a matter for expert opinion. Advances in surgical management have improved outcomes and increased rates of microbiological diagnosis.

Background: Coronavirus disease-2019 (COVID-19) causes severe illness and multi-organ dysfunction. An abnormal electrocardiogram is associated with poor outcome, and QT prolongation during the illness has been linked to pharmacological effects. This study sought to investigate the effects of the COVID-19 illness on the corrected QT interval (QTc).

Aim: To describe the incidence and microbiological characteristics of nosocomial bloodstream infections in childhood over a 9-year period at a South London tertiary hospital.

Methods: Analysis of prospective data collected for clinically significant nosocomial bloodstream infections in children aged <16 years during 2001-2009.

Results: During the study period, although the absolute number of nosocomial bloodstream infections were similar for the neonatal unit (n = 254) and paediatric wards (n = 224), rates were 11.

Whole-genome analysis by 62-strain microarray showed variation in resistance and virulence genes on mobile genetic elements (MGEs) between 40 isolates of methicillin-resistant Staphylococcus aureus (MRSA) strain CC22-SCCmecIV but also showed (i) detection of two previously unrecognized MRSA transmission events and (ii) that 7/8 patients were infected with a variant of their own colonizing isolate.

Of 840 patients at hospital admission, 2.7% were positive for methicillin-resistant Staphylococcus aureus (MRSA) and 22.3% were positive for methicillin-susceptible S.

Design: Retrospective case-control study.

Setting: Tertiary neonatal unit in London.

Clostridium difficile can be a fatal hospital-acquired infection and its prevalence has increased. Accurate diagnosis of C difficile is essential for patient management, infection control, and for defining its epidemiology. We did a systematic review of commonly used commercial assays for detection of C difficile toxin (CDT) A and B in stool samples.

Article Synopsis
  • The study aimed to assess the prevalence of pneumococcal bacteria in the noses of young children in London daycare centers and to examine their antibiotic resistance and serotype distribution.
  • During the survey from March to November 2003, swabs were taken from 234 children, revealing that over half carried pneumococci but showed low resistance to penicillin.
  • The findings highlighted a high rate of pneumococcal carriage, with notable differences related to ethnicity and a need for ongoing monitoring of vaccine-related serotypes.

Surveillance of Helicobacter pylori antibiotic susceptibility from patients in London, the largest metropolitan area in the UK, is limited, despite resistance being a key factor in treatment failure. A two-centre survey was performed over 12 months (1999-2000) to determine antibiotic-resistance rates of isolates from dyspeptic patients attending endoscopy clinics serving two ethnically diverse central and south London communities. The in vitro antibiotic susceptibilities were determined from disc diffusion and epsilometer (E) tests on 101 H.

In the past few years, we have detected in the United Kingdom and in the United States several isolates of Candida glabrata that grew poorly unless bile was available. Cholesterol, a component of bile, stimulated equivalent growth of the bile-dependent isolates. The bile-dependent C.

Recent studies have shown a difference in the genotype of resistant bacteria following passage in animals compared to those passaged in vitro. This suggests that organisms rapidly adapt to their environment of growth. We sought to investigate whether this phenomenon occurred in human infection and whether changes could be detected in the fitness (growth velocity) of isolates transmitted between human hosts.
