An invisible threat? Aspergillus positive cultures and co-infecting bacteria in airway samples.

Background: Aspergillus fumigatus (Af) infection is associated with poor lung health in chronic suppurative lung diseases but often goes undetected. We hypothesised that inhibition of Af growth by Pseudomonas aeruginosa (Pa) increases the frequency of false-negative Af culture in co-infected people. Using a substantial group of cystic fibrosis (CF) airway samples, we assessed the relationship between Af and bacterial pathogens, additionally comparing fungal culture with next-generation sequencing.

Clinical characteristics of Pseudomonas and Aspergillus co-infected cystic fibrosis patients: A UK registry study.

Background: Pseudomonas aeruginosa (Pa) and Aspergillus species (Asp) are the most common bacterial and fungal organisms respectively in CF airways. Our aim was to examine impacts of Asp infection and Pa/Asp co-infection.

Methods: Patients on the UK CF Registry in 2016 were grouped into: absent (Pa-), intermittent (Pai) or chronic Pa (Pac), each with Asp positive (Asp+) or negative (Asp-).

Delayed hepato-spleno-renal bypass for renal salvage following malposition of an infrarenal aortic stent-graft.

Purpose: To report a salvage maneuver for accidental coverage of both renal arteries during endovascular aneurysm repair (EVAR) of an infrarenal aortic aneurysm (AAA) and survey our surgical colleagues in the UK for their use of this bypass procedure.

Methods: A 74-year-old woman who had an EVAR complicated by renal failure secondary to malposition of the stent-graft underwent successful delayed renal revascularization with hepatorenal and splenorenal bypasses. This case prompted a literature review and preparation of an online 6-part questionnaire regarding the incidence and management of renal impairment following EVAR.
