Diuron environmental levels effects on marine nematodes: Assessment of ecological indices, taxonomic diversity, and functional traits
2021
Abstract Coastal marine systems are the most sensitive zones to emerging pollutants. The present study aims to investigate the effect of Diuron on the meiofaunal assemblages, collected from the Bizerte channel (Tunisia). Microcosm experiments were set up using four increasing Diuron concentrations [D1 (10 ng g−1 dry weight (DW)), D2 (50 ng g−1 DW), D3 (250 ng g−1 DW) and (1250 ng g−1 DW)] compared to non-contaminated sediments (controls) and all plots were incubated for 30 days. Our results show that Diuron-supplemented sediments provoked the significant decrease of meiofaunal abundance as well as a change in nematodes' diversity and structure composition. All univariate indices, as well as…
Can grassland plant communities be preserved on road and railway verges?
2000
Semi-natural grasslands are a threatened biotope type in many countries. Typical grassland plant species are adapted to continuous grazing or mowing that keeps the envi- ronment open. With the decline in grassland area, these spe- cies are ever more reliant on alternative habitats such as road verges. To find out whether plant communities comparable to those of semi-natural grasslands can be maintained on modern road and railway sides, the vegetation of 92 grasslands and 90 road and railway verges was studied. These biotope types were compared with each other according to their community structure, total number of species, number of grassland species and restricted-range diversity. Further …
Isolation and identification of intermediates from biodegradation of low chlorinated biphenyls (Delor-103).
2004
Abstract Microorganism Pseudomonas species P2 metabolizes polychlorinated biphenyls (PCBs) and biphenyl, producing the whole spectrum of intermediates, among them coloured intermediates, which are suitable for the monitoring of PCBs degradation by optical sensors. Knowledge of chemical structures and conditions of development of colour metabolites is necessary for application of optical analytical methods. The main goal of this work was the isolation and identification of intermediates from the biodegradation of the mixture of low chlorinated biphenyls (Delor-103), which is based on the solid phase extraction (SPE) of the whole mixture using LiChrolut EN cartridges, then silylation of the e…
Biomonitoring of Phthalates, Bisphenols and Parabens in Children: Exposure, Predictors and Risk Assessment
2021
Exposure to emerging contaminants, such as phthalates, bisphenols and parabens in children has been associated with possible neurodevelopment and endocrine alterations. In the present study, the biomonitoring of biomarkers in children (5–12 years old) from the Valencia Region (Spain) have been implemented using urines from the BIOVAL program. More than 75% of the children studied (n = 562) were internally exposed (>
Frequent and severe hypoglycaemia detected with continuous glucose monitoring in older institutionalised patients with diabetes.
2021
AbstractBackgroundLittle is known about the prevalence of hypoglycaemia in older people with diabetes. However, the HbA1c goal is ≥8% for institutionalised patients with treatments that can cause hypoglycaemia.PurposeWe aimed to assess the prevalence of hypoglycaemia with continuous glucose monitoring and to evaluate the link with HbA1C in older institutionalised patients with diabetes taking potentially hypoglycaemia-inducing drugs.DesignProspective, multicentre study carried out in six geriatric care centres in the Côte d’Or region of France between January 2019 and July 2020.Settings, subjects and methodsA FreeStyle Libre Pro® (FSLP) was worn for up to 14 days in blinded mode in 42 patie…
Are older patients with diabetes still being overtreated in French long-term care homes?
2020
Abstract Background Diabetes management has not been evaluated in French nursing homes (NHs) for 10 years. Objectives The present study aimed to compare the management of diabetes with guidelines in older patients living in NHs. Design Observational, retrospective and multicentre study carried out in 13 NH in the Cote d’Or region of France. Settings and subjects Between January and June 2018, all NH residents older than 65 years and known to have diabetes (n = 148) were included. Methods Epidemiological, clinical and biological data and diabetes characteristics were collected from the medical records. Results The average glycated haemoglobin (HbA1C) was 7.2 ± 1.2%. In total, 51% of patients…
A Worldwide Perspective on COVID-19 and Diabetes Management in 22,820 Children from the SWEET Project: Diabetic Ketoacidosis Rates Increase and Glyce…
2021
Aims: To investigate the short-term effects of the first wave of COVID-19 on clinical parameters in children with type 1 diabetes (T1D) from 82 worldwide centers participating in the Better Control in Pediatric and Adolescent DiabeteS: Working to CrEate CEnTers of Reference (SWEET) registry. Materials and Methods: Aggregated data per person with T1D £21 years of age were compared between May/June 2020 (first wave), August/September 2020 (after wave), and the same periods in 2019. Hierarchic linear and logistic regression models were applied. Models were adjusted for gender, age-, and diabetes duration-groups. To distinguish the added burden of the COVID-19 pandemic, the centers were divided…
Study of Glycemic Variability Through Time Series Analyses (Detrended Fluctuation Analysis and Poincaré Plot) in Children and Adolescents with Type 1…
2016
Time series analysis provides information on blood glucose dynamics that is unattainable with conventional glycemic variability (GV) indices. To date, no studies have been published on these parameters in pediatric patients with type 1 diabetes. Our aim is to evaluate the relationship between time series analysis and conventional GV indices, and glycosylated hemoglobin (HbA1c) levels.This is a transversal study of 41 children and adolescents with type 1 diabetes. Glucose monitoring was carried out continuously for 72 h to study the following GV indices: standard deviation (SD) of glucose levels (mg/dL), coefficient of variation (%), interquartile range (IQR; mg/dL), mean amplitude of the la…
Chronic consumption of an inositol-enriched carob extract improves postprandial glycaemia and insulin sensitivity in healthy subjects: A randomized c…
2016
Background & aims: Inositols are thought to be mediators of the insulin signalling pathway. We assessed the effects of inositols on glycaemic control in fasting and postprandial states and evaluated lipoprotein profile and LDL particle size in healthy population. Methods: A 12-week double-blind clinical trial was performed with forty healthy subjects administered either an inositol-enriched beverage (IEB) -containing 2.23 g of inositols in 250 ml- or a sucrose-sweetened beverage (SB) twice a day. Anthropometric measurements, fasting glucose levels, insulin and HOMA-IR index, lipoprotein profile and postprandial glucose concentrations (measured using the continuous glucose monitoring system …
Real-time estimation of plasma insulin concentration from continuous glucose monitor measurements
2015
Continuous glucose monitors can measure interstitial glucose concentration in real time for closed-loop glucose control systems, known as artificial pancreas. These control systems use an insulin feedback to maintain plasma glucose concentration within a narrow and safe range, and thus to avoid health complications. As it is not possible to measure plasma insulin concentration in real time, insulin models have been used in literature to estimate them. Nevertheless, the significant interand intra-patient variability of insulin absorption jeopardizes the accuracy of these estimations. In order to reduce these limitations, our objective is to perform a real-time estimation of plasma insulin co…
