11 and 15-month-old infants do not compensate immediately for energy variation, and no further adjustment occurs 12 or 24 hours later
2021
International audience; Previously, we demonstrated that, in the short term, infants undercompensated for the energy from a preload given 25 min before an ad libitum meal. However, although not consistent, there is evidence in young children that caloric adjustment may occur over longer periods. We investigated the extent to which further energy adjustment occurs up to 24 h after a single meal preceded by preloads of varying energy density (ED) in infants that are 11 and 15 months old. Short-term caloric adjustment was measured in 11- and 15-month-old infants through a preload paradigm meal in the laboratory. To assess their caloric adjustment over longer periods (12 and 24 h), we used 24 h…
Population pharmacokinetic meta-analysis of individual data to design the first randomized efficacy trial of vancomycin in neonates and young infants.
2019
Abstract Objectives In the absence of consensus, the present meta-analysis was performed to determine an optimal dosing regimen of vancomycin for neonates. Methods A ‘meta-model’ with 4894 concentrations from 1631 neonates was built using NONMEM, and Monte Carlo simulations were performed to design an optimal intermittent infusion, aiming to reach a target AUC0–24 of 400 mg·h/L at steady-state in at least 80% of neonates. Results A two-compartment model best fitted the data. Current weight, postmenstrual age (PMA) and serum creatinine were the significant covariates for CL. After model validation, simulations showed that a loading dose (25 mg/kg) and a maintenance dose (15 mg/kg q12h if <…
European countries in the race to attract successful biopharma investment: Winners and laggers
2021
The post-coronavirus era will open myriad opportunities for the biopharma industry. However, the extent to which each country will take advantage of this promising new scenario will largely depend on its position in a few key areas. Here, we offer an overview of the European countries that are winning and those that are lagging behind in the race to attract the greatest investment in this industry and to attain the highest rate of successful new ventures. Our results highlight the vital importance of a sound, active funding base, especially in terms of venture capital. Our findings also suggests that general scientific foundations are not enough to secure an advantage in new venture formati…

Deciphering function of the pulmonary arterial sphincters in loggerhead sea turtles (Caretta caretta)
2018
To provide new insight to the pathophysiological mechanisms underlying gas emboli (GE) in bycaught loggerhead sea turtles (Caretta caretta), the present study investigated the vasoactive characteristics of the pulmonary and systemic arteries, and the lung parenchyma (LP). Tissues were opportunistically excised from recently dead animals for in vitro studies of vasoactive responses to four different neurotransmitters: acetylcholine (ACh, parasympathetic), serotonin (5HT), epinephrine (Epi, sympathetic) and histamine. The significant amount of smooth muscle in the LP contracted in response to ACh, Epi and histamine. The intrapulmonary and systemic arteries contracted under both parasympatheti…
Mechanisms underlying the influence of oestrogen on cardiovascular physiology in women.
2019
Women show a lower incidence of cardiovascular diseases than age-matched men, but this benefit disappears after menopause. Oestrogen-mediated vascular actions are mainly attributed to oestradiol and exerted by oestrogen receptors (ERα, ERβ and G protein-coupled oestrogen receptor), through rapid and/or genomic mechanisms, but these effects depend on ageing and inflammation. A cardiovascular approach in women's health has arisen due to controversy regarding oestrogen's beneficial impact as reported in experimental and observational studies and large randomized trials. These can be explained, in part, by two mutually non-exclusive hypotheses. On the one hand, the timing hypothesis, which stat…
Algorithm for the management of patients at low, high and very high risk of osteoporotic fractures
2019
Summary Guidance is provided in an international setting on the assessment and specific treatment of postmenopausal women at low, high and very high risk of fragility fractures. Introduction The International Osteoporosis Foundation and European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis published guidance for the diagnosis and management of osteoporosis in 2019. This manuscript seeks to apply this in an international setting, taking additional account of further categorisation of increased risk of fracture, which may inform choice of therapeutic approach. Methods Clinical perspective and updated literature search. Results The following areas are reviewed: …
Treatments for post-menopausal osteoporotic women, what's new? How can we manage long-term treatment?
2016
Since the mid-1980s, postmenopausal osteoporosis (PMO) has been considered a serious public health concern because of the associated fractures. Pharmacological therapies that effectively reduce the number of fractures by improving bone mass have been and are being developed continuously. Most current agents inhibit bone loss by reducing bone resorption, but emerging therapies may increase bone mass by stimulating bone formation. Furthermore, nowadays, the most representative pharmaceuticals have been prescribed long enough to include the reporting of some adverse effects. This review discusses osteoporotic drugs that are approved or are under investigation for the treatment of post-menopaus…
Does endogenous serum oestrogen play a role in meibomian gland dysfunction in postmenopausal women with dry eye?
2016
Aim To explore the relationship between serum concentration of sex hormones and dry eye symptoms and signs in postmenopausal women. Methods A cross-sectional analysis was undertaken. Subjects were 46 postmenopausal women with dry eye (mean age 64.4±5.2 years, 13.7±6.4 years since menopause; not undergoing hormone replacement therapy). Ocular symptoms (Ocular Surface Disease Index (OSDI) and Ocular Comfort Index (OCI)), tear function (tear osmolarity, non-invasive tear break-up time, tear secretion), corneal and conjunctival staining, and meibomian gland (MG) appearance, were recorded. Venous blood was collected and serum concentrations of 17β-oestradiol (E2), 3-α-androstanediol-glucuronide …
Women in LOVe: Lacto-Ovo-Vegetarian Diet Rich in Omega-3 Improves Vasomotor Symptoms in Postmenopausal Women. An Exploratory Randomized Controlled Tr…
2019
Objective:In the postmenopausal period, most women suffer vasomotor symptoms (VMS). It is well-known that VMS can worsen the quality of life. Diet seems to play a relevant role in the development of VMS, but the effect of diet on VMS is mainly limited to observational studies, and analyses of nutritional supplements. The aim of this study was thus to determine the efficacy of a lactoovo- vegetarian (LOVe) diet rich in omega-3 fatty acids vs. a lacto-ovo-vegetarian diet rich in EVO (extra-virgin olive oil) in reducing VMS frequency in postmenopausal women.Methods:A two-arms (lacto-ovo-vegetarian diet with EVO vs. lacto-ovo-vegetarian diet rich in omega-3) randomized-controlled trial with a f…
