Filter by:Cloth masks have been evaluated as a potential substitute for personal protective equipment (PPE) and found lacking. Prior to the COVID-19 outbreak, the use of cloth masks was limited and the focus of the limited research available was on the filtration of various fabrics in comparison to either surgical masks or N95 respirators. The Centers for Disease Control and Prevention (CDC) guidance for the coronavirus (COVID-19) outbreak makes it clear that cloth masks are not to be considered as PPE for healthcare workers and should be used in the healthcare setting only as a last resort when no other masks or respirators are available. While cloth masks are not recommended to be used as PPE, the use of cloth masks as primary source control has not yet been examined.
What impact can facial masks have on face exploration in the first few weeks of life? No study has yet investigated this. The objective of our study was to evaluate the impact of the mask on the face processing (preferential gaze, visual recognition) of the term infant for familiar (e.g. mother's face) and unfamiliar (stranger's face) faces. This is a prospective study which will take place in Grenoble Maternity Hospital. 200 newborns will be enrolled between 24 hours and 7 days of life during one year. Different pairs of images will be presented on a screen while an experimenter records the infant's gaze. On each trial, the experimenter will judge when the infant is looking at the screen or not and assess when 10 seconds of screen gaze time has been accumulated. The comparisons will be made to determine whether statistically, one face is looked at significantly longer than another.
The purpose of this study will be to assess the effects of the use of masks on inspiratory muscle strength, metabolic parameters, heart rate, subjective perception of effort and the sensation of dyspnea before, during and after an aerobic test of 30 minutes long and a fixed load at lactate threshold. A randomized study of repeated measures will be carried out. A total sample of 35 active participants will be recruited. All participants will carried out a lactate threshold test and then 3 visits to the laboratory (separated at least 48 hours from each other) in order to perform 3 test of 30 minutes long without mask, with a surgical mask or with a FFP2 respirator (in a randomized order) at an intensity around lactate threshold intensity. Maximal inspiratory pressure, oxygen saturation, heart rate, blood lactate concentration, subjective perception of effort and dyspnea will be assessed before, during and after the 3 fixed intensity tests.
The study aim will be to determine the fit factor of surgical masks and filtering respirators in healthcare providers with and without beard. A randomized clinical trial will be carried out recruiting a sample of 52 healthcare providers with and without beard. Fit factor will be measured with both surgical masks and filtering respirators and compared between healthcare providers with and without beard.
