Delayed vs Immediate Cord Clamping Changes Oxygen Saturation and Heart Rate Patterns in the First Minutes after Birth
2020
Objective To build arterial oxygen saturation (SpO2) and heart rate (HR) percentiles for the first 10 minutes after birth in term infants born after an uneventful gestation, vaginal delivery, and delayed cord clamping (DCC) for ≥60 seconds, and to compare our results with previous ones constructed after immediate cord clamping. Study design Preductal SpO2, HR, and timing of DCC immediately after complete fetal body expulsion were recorded. The pulse-oximeter was adjusted in the right wrist/hand and set at maximal intensity and measurements performed every 2 seconds. Results A total of 282 term newborn infants were included. The definitive data set comprised of 70 257 SpO2 and 79 746 HR meas…
Odorization of a novel object can influence infant's exploratory behavior in unexpected ways.
2008
International audience; Although much is known about the development of object exploration during infancy, it remains to be understood whether and how olfaction can influence infants' interactions with novel objects. To address these issues, sixteen infants aged 7-15 months were videotaped during two consecutive 5-min free play sessions with a scented or an unscented version of visually similar objects. Results indicate that adding an odor to a novel object influenced the infants' behavior: the infants exhibited more and longer manipulations and mouthing of the unscented object than of the scented object. The differential responsiveness to the scented, relative to the unscented, object was …
Associations of black carbon with lung function and airway inflammation in schoolchildren
2019
Background: Few studies have investigated the 24-hour respiratory health effects of personal black carbon (BC) and ultrafine particles (UFP) exposure in schoolchildren. The objective of this study was to investigate these associations with the lung function in children 10-years old with and without persistent respiratory symptoms. Methods: We conducted a cross-sectional study in 305 children (147 and 158 with and without persistent respiratory symptoms, respectively) from three European birth-cohorts: PARIS (France) and INMA Sabadell and Valencia (Spain). Personal 24-hour measurements of exposure concentrations to BC and UFP were performed by portable devices, before lung function testing. …
Liking the odour, liking the food. Toddlers' liking of strongly flavoured foods correlates with liking of their odour
2014
Olfaction plays a significant role in the sensing of foods. However, little information is available at any age on the relationship between the hedonic responses to given food odours and the effective liking and disliking of foods bearing these same odours. The present study aimed to assess the relationships between food odour liking and liking of the corresponding foods. This study relied on a longitudinal design involving 235 toddlers who were assessed for both their observed liking of a set of food odours and their parent-reported liking of foods at 12 and 22 months. To assess odour liking, eight odorants representing pleasant and unpleasant foods were presented in bottles along with neu…
Modulation of Spatial O2Tension Distribution in Experimental Tumors by Increasing Arterial O2Supply
1995
Tumor oxygenation has been measured polarographically in s.c. implanted DS-sarcomas on the dorsum of the hind foot of male Sprague-Dawley rats. pO2 was determined in all 3 spatial dimensions and 3-dimensional pO2 distributions as well as the mean extent of confluent areas with pO25 mmHg were calculated. Finally, the effect of elevating arterial pO2 (by carbogen breathing) as well as of increasing tumor blood flow (by angiotensin infusion) on the spatial pO2 distribution was analyzed. Depending on the tumor volume, the spatial pO2 distribution is more or less anisotropic. In smaller tumors, areas with physiological pO2 values are found adjacent to large hypoxic areas whereas larger tumors ar…
Is Overall Mortality the Right Composite Endpoint in Clinical Trials of Acute Respiratory Distress Syndrome?
2018
Objectives Overall mortality in patients with acute respiratory distress syndrome is a composite endpoint because it includes death from multiple causes. In most acute respiratory distress syndrome trials, it is unknown whether reported deaths are due to acute respiratory distress syndrome or the underlying disease, unrelated to the specific intervention tested. We investigated the causes of death after contracting acute respiratory distress syndrome in a large cohort. Design A secondary analysis from three prospective, multicenter, observational studies. Setting A network of multidisciplinary ICUs. Patients We studied 778 patients with moderate-to-severe acute respiratory distress syndrome…
Airway cell composition at rest and after an all-out test in competitive rowers
2004
Med Sci Sports Exerc. 2004 Oct;36(10):1723-9. Airway cell composition at rest and after an all-out test in competitive rowers. Morici G, Bonsignore MR, Zangla D, Riccobono L, Profita M, Bonanno A, Paternò A, Di Giorgi R, Mirabella F, Chimenti L, Benigno A, Vignola AM, Bellia V, Amato G, Bonsignore G. SourceDepartment of Experimental Medicine Italian National Research Council (CNR), Palermo, Italy. Abstract PURPOSES: This study was designed to assess: a) whether rowing affects airway cell composition, and b) the possible relationship between the degree of ventilation during exercise and airway cells.

Pulmonary effects of expiratory-assisted small-lumen ventilation during upper airway obstruction in pigs
2015
Summary Novel devices for small-lumen ventilation may enable effective inspiration and expiratory ventilation assistance despite airway obstruction. In this study, we investigated a porcine model of complete upper airway obstruction. After ethical approval, we randomly assigned 13 anaesthetised pigs either to small-lumen ventilation following airway obstruction (n = 8) for 30 min, or to volume-controlled ventilation (sham setting, n = 5). Small-lumen ventilation enabled adequate gas exchange over 30 min. One animal died as a result of a tension pneumothorax in this setting. Redistribution of ventilation from dorsal to central compartments and significant impairment of the distribution of ve…
Light exposure of the lower leg as a pathogenetic factor in the occurrence of malignant melanoma.
1992
Of the 1,198 women and men studied in Mainz from 1966 to 1987 there was an approximately fivefold increase in the incidence of melanoma. Among the men melanomas on the trunk (59.9%) predominated, whereas among the women melanomas on the extremities (40.0%) were more common, especially on the lower leg (26.3%). Comparing the decades 1966-1976 and 1977-1987 there was a significant decrease in melanomas affecting women's lower legs (1966-1976: 33%,; 1977-1987: 24.2%). Fashion-dependent sun exposure of this body area might offer an explanation. It could be demonstrated that common stocking materials do not sufficiently protect against UV radiation (average permeability for UV light about 55%), …
The cadence and water temperature effect on physiological responses during water cycling
2013
The aim of the study was to compare the maximal physiological responses during three protocols: maximal test on land cycle ergometer, maximal test on water cycling in an indoor pool at 27 °C (WC27) and at 31 °C (WC31). Moreover, the submaximal physiological responses were compared according cycling cadences and water temperatures during the water protocols. Ten young men were included and performed the protocols in separate days. Blood lactate (BL) concentration, heart rate (HR), oxygen uptake (VO2), ventilation (VE) and thermal comfort (TC) were collected during the exercise. The maximal HR and VO2 showed no significant differences between the protocols: HRmax: 189 ± 7 (Land), 188 ± 14 (WC…
