Predictive factors found to be independently associated with vaccination on multivariable analysis were past vaccinations, low-risk malignancy, and country of birth. In the analysis conducted among interviewees (N?=?561), recommendations from the oncologist (OR?10.7, 95%?CI?5.4�C21.2) and from the primary-care physician (OR?3.35, 95%?CI?2.05�C5.49) were strong predictors for vaccination. We conclude that ��habitual vaccinees�� continue influenza vaccinations when ill with cancer. Physicians' recommendations, especially the oncologist's, have a major influence on patients' compliance with influenza vaccination. ""With this special issue on the matrix-assisted laser desorption-ionization time-of-flight (MALDI-TOF) mass spectrometry, our aim is that infectious [http://en.wikipedia.org/wiki/Tryptophan_synthase Tryptophan synthase] diseases specialists and microbiologists not yet familiar with this new tool will appreciate the importance of this ��magical laser�� for microbial identification. We hope that even specialists will appreciate this overview on this new technology and its applications, since MALDI-TOF mass spectrometry really represents a quantum leap in diagnostic microbiology. In their review article, Emonet et al. thoroughly explain how MALDI-TOF mass spectrometry allows identification of bacterial species available in pure culture. They also compare the different mass spectrometer specifically adapted to routine microbiology laboratories and discuss their respective [http://www.selleckchem.com/PI3K.html PI3K signaling pathway] advantages and disadvantages. Then, they nicely present two other recent mass spectrometry-based tools, i.e. the MALDI-resequencing (MALDI-RE) and the association of a new broad-range PCR approach coupled with the analysis of generated amplicons by electrospray ionization mass spectrometry (PCR-ESI-MS), that allows better discrimination of strains and may be performed directly on clinical samples without a [http://www.selleckchem.com/products/ch5424802.html selleck screening library] culture-based amplification step. In the second article of this special issue, Bizzini and I present the performance of MALDI-TOF mass spectrometry in routine setting. Although current protocols allow accurate identification of most strains routinely isolated in clinical microbiology laboratories, some clades will repeatedly be misidentified due to poor quality of databases or due to the close relatedness of different species (i.e. within the Streptococcus genus; or between E.?coli and Shigella species). Despite these limitations, MALDI-TOF mass spectrometry really appears as a quantum leap in diagnostic microbiology that significantly reduce the time to results and costs of microbial identification.
