Seroprevalence of SARS-CoV-2 antibody among healthcare workers in a university hospital in Mallorca, Spain, during the first wave of the COVID-19 pandemic.

Objective: To estimate the SARS-CoV-2 antibody seroprevalence in healthcare workers (HCWs) at a university hospital in Mallorca, Spain.

Methods: All HCWs received an e-mail inviting them to take part in the study. Participants had a nasopharyngeal swab test performed for reverse transcriptase quantitative polymerase chain reaction (RT-qPCR) and serological tests to detect SARS-CoV-2 antibodies (primary study).

Pharmacodynamics of amphotericin B deoxycholate, amphotericin B lipid complex, and liposomal amphotericin B against Aspergillus fumigatus.

Amphotericin B is a first-line agent for the treatment of invasive aspergillosis. However, relatively little is known about the pharmacodynamics of amphotericin B for invasive pulmonary aspergillosis. We studied the pharmacokinetics (PK) and pharmacodynamics (PD) of amphotericin B deoxycholate (DAMB), amphotericin B lipid complex (ABLC), and liposomal amphotericin B (LAMB) by using a neutropenic-rabbit model of invasive pulmonary aspergillosis.

Are we missing opportunities to confirm the diagnosis of tuberculosis by microbial culture?

Setting: Tuberculosis (TB) incidence is rising globally, with drug resistance becoming increasingly problematic. Microbiological confirmation ensures correct anti-tuberculous chemotherapy.

Objective/design: We retrospectively analysed all TB cases diagnosed in Central Manchester in 2009 investigating how often we are not achieving microbiological diagnosis, factors influencing this and whether opportunities to obtain microbiological samples are missed.

Pharmacokinetics and pharmacodynamics of fluconazole for cryptococcal meningoencephalitis: implications for antifungal therapy and in vitro susceptibility breakpoints.

Fluconazole is frequently the only antifungal agent that is available for induction therapy for cryptococcal meningitis. There is relatively little understanding of the pharmacokinetics and pharmacodynamics (PK-PD) of fluconazole in this setting. PK-PD relationships were estimated with 4 clinical isolates of Cryptococcus neoformans.

Combination of voriconazole and anidulafungin for treatment of triazole-resistant aspergillus fumigatus in an in vitro model of invasive pulmonary aspergillosis.

Voriconazole is a first-line agent for the treatment of invasive pulmonary aspergillosis. Isolates with elevated voriconazole MICs are increasingly being seen, and the optimal treatment regimen is not defined. We investigated whether the combination of voriconazole with anidulafungin may be beneficial for the treatment of A.

Pharmacodynamics of voriconazole in a dynamic in vitro model of invasive pulmonary aspergillosis: implications for in vitro susceptibility breakpoints.

Background: Voriconazole is a first-line agent for the treatment of invasive pulmonary aspergillosis (IPA). There are increasing reports of Aspergillus fumigatus isolates with reduced susceptibility to voriconazole.

Methods: An in vitro dynamic model of IPA was developed that enabled simulation of human-like voriconazole pharmacokinetics.

Pharmacodynamics of itraconazole against Aspergillus fumigatus in an in vitro model of the human alveolus: perspectives on the treatment of triazole-resistant infection and utility of airway administration.

Itraconazole is used for the prevention and treatment of infections caused by Aspergillus fumigatus. An understanding of the pharmacodynamics of itraconazole against wild-type and triazole-resistant strains provides a basis for innovative therapeutic strategies for treatment of infections. An in vitro model of the human alveolus was used to define the pharmacodynamics of itraconazole.

[Efficiency of the home intravenous antibiotics treatment in cystic fibrosis].

Background And Objective: The objective of our study was to determine the costs saving with the implementing of a home intravenous antibiotic treatment (HIVAT) program for patients with cystic fibrosis and to compare it with the conventional system (inpatient).

Patients And Method: Consecutive patients in an adults cystic fibrosis unit were selected who received some days of HIVAT, between January 2002 and December 2004. For the analysis of costs saving of the HIVAT, we used the difference between the total costs of the avoided stay days and the costs generated by the domiciliary therapy (drugs, expendable equipment) and by the ambulatory medicine unit in case the patients were not hospitalized.
