BACKGROUND: The implementation of MALDI-TOF MS for microorganism identification has changed the routine of the microbiology laboratories as we knew it. Most microorganisms can now be reliably identified within minutes using this inexpensive, user-friendly methodology. However, its application in the identification of mycobacteria isolates has been hampered by the structure of their cell wall. Improvements in the sample processing method and in the available database have proved key factors for the rapid and reliable identification of non-tuberculous mycobacteria isolates using MALDI-TOF MS. AIMS: The main objective is to provide information about the proceedings for the identification of non-tuberculous isolates using MALDI-TOF MS and to review different sample processing methods, available databases, and the interpretation of the results. SOURCES: Results from relevant studies on the use of the available MALDI-TOF MS instruments, the implementation of innovative sample processing methods, or the implementation of improved databases are discussed. CONTENT: Insight about the methodology required for reliable identification of non-tuberculous mycobacteria and its implementation in the microbiology laboratory routine is provided. IMPLICATIONS: Microbiology laboratories where MALDI-TOF MS is available can benefit from its capacity to identify most clinically interesting non-tuberculous mycobacteria in a rapid, reliable, and inexpensive manner.

BACKGROUND: Drug development for Alzheimer disease (AD) is challenged by the success in animal models tested in the Morris water maze (MWM) and the subsequent failures to meet primary outcome measures in phase II or III clinical trials in patients. The human variant of MWM (hMWM) enables us to examine allocentric and egocentric navigation as in the MWM. OBJECTIVE: It was the aim of this study to examine the utility of a computerized hMWM to assess the effects of donepezil in mild AD. METHODS: Donepezil 5 mg/day was started after initial hMWM testing in the treated group (n = 12), and after 28 days, the dose was increased to 10 mg/day. The performance after 3 months was compared to that of a non-treated group (n = 12). RESULTS: Donepezil stabilized or improved the spatial navigation performance after 3 months, especially in the allocentric delayed recall subtask (p = 0.014). CONCLUSIONS: The computerized hMWM has the potential to measure the effects of donepezil in mild AD. It is a sensitive cognitive outcome measure in AD clinical trials.
