Influenza vaccination for immunocompromised patients: systematic review and meta-analysis from a public health policy perspective.

Immunocompromised patients are vulnerable to severe or complicated influenza infection. Vaccination is widely recommended for this group. This systematic review and meta-analysis assesses influenza vaccination for immunocompromised patients in terms of preventing influenza-like illness and laboratory confirmed influenza, serological response and adverse events

Application of dynamical ion mixing techniques to the improvement of the fatigue resistance of a 316L stainless steel

In the last years new techniques involving ion implantation combined with a simultaneous deposition method in a sputtering evaporator have been developed at the University of Poitiers. These techniques have been employed to elaborate NiTi amorphous coatings in order to improve the fatigue resistance of a 316 L austenitic stainless steel at room temperature and 573 K. It has been shown that a significant improvement of the fatigue life is obtained by this way at 293 K and at 573 K due to a considerable modification of surface damage leading to an important delay for crack initiation
