Normal values of forced vital capacity (FVC), forced expiratory volume (FEV 1-0), and peak flow rate (PFR) in children.

The normal values in children for the forced vital capacity (FVC), the forced expiratory volume in one second (FEVI.,), and the peak flow rate (PFR) have been determined in a group of 261 healthy schoolchildren. Charts which allow the ready determination of these values have been presented

Oxidative and nonoxidative glucose metabolism following graded doses of oral glucose in man.

The oxidative and nonoxidative glucose metabolism represent the two major mechanisms of the utilization of a glucose load. Eight normal subjects were administered oral loads of 50, 100 and 150 g glucose and gas exchange measurements were performed for eight hours by means of computerized continuous indirect calorimetry. The glycemic peaks were almost identical with all three doses with a rise to between 141 and 147 mg/dl at 60 min. The fall back to basal level was reached later with the high than with the low glucose doses. The glucose oxidation rate rose to values between 223 and 253 mg/min after the three glucose doses, but while falling immediately after the peak at 120 min following the 50 g load, the glucose oxidation rate remained at its maximum rate until 210 min for the 100 g glucose load and plateaued up to 270 min for the 150 g glucose dose. The oxidation rates then fell gradually to reach basal levels at 270, 330 and 420 min according to the increasing size of the load. Altogether 55 +/- 3 g glucose were oxidized during the 8 hours following the 50 g glucose load, 75 +/- 3 g after the 100 g load and 80 +/- 5 g after the 150 g load. The nonoxidative glucose disposal, which corresponds essentially to glucose storage, varied according to the size of the glucose load, with uptakes of 20 +/- 1, 60 +/- 1 and 110 +/- 1 g glucose 180 min after the 50, 100 and 150 g glucose loads respectively.(ABSTRACT TRUNCATED AT 250 WORDS

Decreased thermogenic response to an oral glucose load in older subjects.

The thermogenic response to a 100 g oral glucose load was studied by indirect calorimetry in 13 older persons (age range, 38-68 years) and compared with that of 16 young matched controls of similar body weight (age range, 19-30 years). The glucose-induced thermogenesis measured over 180 min and expressed as a per cent of the energy content of the glucose load was found to be reduced in the older subjects, i.e., 5.8 +/- 0.3 per cent vs 8.6 +/- 0.7 per cent, P less than 0.002). This was also accompanied by a significant decrease in the glucose oxidation rate when averaged over the same three-hour period following the glucose load, i.e., 153 mg/min vs 213 mg/min in the control subjects (P less than 0.001) despite a similar time course of glycemia. This study suggests that the thermogenic response to an oral glucose load is blunted in older people, and this may represent an additional factor that contributes to the decreased energy requirement with age and therefore to the increased propensity to obesity if energy intake is not adjusted

Feeding effects of Ischnodemus variegatus (Hemiptera: Blissidae) on photosynthesis and growth of Hymenachne amplexicaulis (Poaceae)

The influence of Ischnodemus variegatus feeding on photosynthesis and growth of the invasive semi-aquatic grass, Hymenachne amplexicaulis, was investigated in field and greenhouse environments. In the field, carbon dioxide assimilation of infested plants was approximately 35% less than that of non-infested plants, and the rate of assimilation was related to I. variegatus density. The relative growth rate of infested plants in the greenhouse was 77% of that of non-infested plants, and biomass of infested plants was significantly less than for non-infested plants 79 days after infestation. The value of I. variegatus as a fortuitous biological control agent of H. amplexicaulis is discussed

Fibromyalgie et lombalgie chronique : étude des facteurs invalidants et facteurs facilitateurs à la réinsertion et au maintien professionnel

Cette recherche a pour objectif de mettre à jour les différents facteurs invalidants ou favorisant la réintégration au travail et le maintien professionnel de patientes atteintes de deux types de maladies : la fibromyalgie ou la lombalgie chronique. En effet, les études actuelles sur la réinsertion et le maintien au travail sont généralement axées sur ces deux facteurs, mais elles n’envisagent pas la perspective d’une vision complémentaire de ceux-ci. Ce faisant, notre étude a permis de mettre en évidence l’association de ces deux approches mais également de révéler des différences et certaines similarités entre les patientes.The aim of this research is to explore the invalidating and facilitating factors related to return to work and/or to maintain work perceived by two groups of patients with chronic diseases: fibromyalgia or chronic back pain. Indeed, the current studies generally examined either return to work or maintaining work; their approach is rarely supported by an integrated view. Our study revealed similarities and differences between the two perspectives but also between the two groups of patients. This will help with the development of future initiatives for returning chronic pain patients to employment
