BACKGROUND: Antimicrobial resistance has been recognised as a global threat with carbapenemase- producing-Enterobacteriaceae (CPE) as a prime example. CPE has similarities to COVID-19 where asymptomatic patients may be colonised representing a source for onward transmission. There are limited treatment options for CPE infection leading to poor outcomes and increased costs. Admission screening can prevent cross-transmission by pre-emptively isolating colonised patients. OBJECTIVE: We assess the relative cost-effectiveness of screening programmes compared with no- screening. METHODS: A microsimulation parameterised with NHS Scotland date was used to model scenarios of the prevalence of CPE colonised patients on admission. Screening strategies were (a) two-step screening involving a clinical risk assessment (CRA) checklist followed by microbiological testing of high-risk patients; and (b) universal screening. Strategies were considered with either culture or polymerase chain reaction (PCR) tests. All costs were reported in 2019 UK pounds with a healthcare system perspective. RESULTS: In the low prevalence scenario, no screening had the highest probability of cost-effectiveness. Among screening strategies, the two CRA screening options were the most likely to be cost-effective. Screening was more likely to be cost-effective than no screening in the prevalence of 1 CPE colonised in 500 admitted patients or more. There was substantial uncertainty with the probabilities rarely exceeding 40% and similar results between strategies. Screening reduced non-isolated bed-days and CPE colonisation. The cost of screening was low in relation to total costs. CONCLUSION: The specificity of the CRA checklist was the parameter with the highest impact on the cost-effectiveness. Further primary data collection is needed to build models with less uncertainty in the parameters.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of coronavirus disease 2019 (COVID-19), may manifest as a life-threatening respiratory infection with systemic complications. Clinical manifestations among children are generally less severe than those seen in adults, but critical cases have increasingly been reported in infants less than 1 year of age. We report a severe case of neonatal COVID-19 requiring intensive care and mechanical ventilation, further complicated by a multidrug-resistant Enterobacter asburiae super-infection. Chest X-rays, lung ultrasound, and chest computed tomography revealed extensive interstitial pneumonia with multiple consolidations, associated with persistent increased work of breathing and feeding difficulties. SARS-CoV-2 RNA was detected in respiratory specimens and stools, but not in other biological samples, with a rapid clearance in stools. Serological tests demonstrated a specific SARS-CoV-2 antibody response mounted by the neonate and sustained over time. The therapeutic approach included the use of enoxaparin and steroids which may have contributed to the bacterial complication, underlying the challenges in managing neonatal COVID-19, where the balance between viral replication and immunomodulation maybe even more challenging than in older ages.

The coronavirus disease 2019 causes a wide degree of organ dysfunction and is associated with bacterial secondary infections. We reported lung microbiota dynamics in a critically ill patient with coronavirus disease 2019, who developed severe Hafnia alvei ventilator-associated pneumonia and required extracorporeal membrane oxygenation support.

At the onset of the COVID-19 crisis, a 63-year-old woman with multiple life-limiting comorbidities was referred with a necrotic infected left breast mass on a background of breast cancer treated with conservation surgery and radiotherapy 22 years previously. The clinical diagnosis was locally advanced breast cancer, but four separate biopsies were non-diagnostic. Deteriorating renal function and incipient sepsis and endocarditis resulted in urgent salvage mastectomy during the peak of the COVID19 pandemic. The final diagnosis was infected ischaemic/infarcted breast (wet gangrene) secondary to vascular insufficiency related to diabetes, cardiac revascularisation surgery and breast radiotherapy.

A 63-year-old diabetic smoker with alcoholism was the first mortality case of coronavirus disease 2019 (COVID-19) in Taiwan. As concurrently infected with Klebsiella pneumoniae and subsequently with Klebsiella aerogenes, he was exposed by a national survey of patients with critically influenza-negative pneumonia. We recommend COVID-19 screening for patients with severe flu-like syndrome and protecting health-care workers from being infected.
