Compliance with antibiotic therapy guidelines in french paediatric intensive care units: a multicentre observational study.

Background: Bacterial infections (BIs) are widespread in ICUs. The aims of this study were to assess compliance with antibiotic recommendations and factors associated with non-compliance.

Methods: We conducted an observational study in eight French Paediatric and Neonatal ICUs with an antimicrobial stewardship programme (ASP) organised once a week for the most part.

Genomics of post-bottleneck recovery in the northern elephant seal.

Populations and species are threatened by human pressure, but their fate is variable. Some depleted populations, such as that of the northern elephant seal (Mirounga angustirostris), recover rapidly even when the surviving population was small. The northern elephant seal was hunted extensively and taken by collectors between the early 1800s and 1892, suffering an extreme population bottleneck as a consequence.

Medical devices used in NICU: The main source of plasticisers' exposure of newborns.

Phthalates and other plasticisers are extensively used in medical devices (MD) from which they can leach out and lead to potential multiple problems for the patients. This exposure is a major issue because it is associated with reproductive and neurodevelopment disorders. The Neonatal Intensive Care Units (NICU) population is at high risk due to the daily intensive medical interventions, the reduced ability of newborns to remove these contaminants and their higher sensitivity to endocrine disruptors.

Estimating population size when individuals are asynchronous: A model illustrated with northern elephant seal breeding colonies.

Our aim was to develop a method for estimating the number of animals using a single site in an asynchronous species, meaning that not all animals are present at once so that no one count captures the entire population. This is a common problem in seasonal breeders, and in northern elephant seals, we have a model for quantifying asynchrony at the Año Nuevo colony. Here we test the model at several additional colonies having many years of observations and demonstrate how it can account for animals not present on any one day.

[Infusion sets in neonatology: What practices in France?].

Objectives: Therapeutic management of ill newborns can require complex infusion practices using medical devices (MD). Currently, there does not exist any recommendations concerning these infusion practices. The objective of this work was to study and characterise French infusion methods neonatal and neonatal intensive care units.

Malignant pertussis in infants: factors associated with mortality in a multicenter cohort study.

Background: Malignant pertussis (MP) affects young infants and is characterized by respiratory distress, perpetual tachycardia and hyperleukocytosis up to 50 G/l, leading to multiple organ failure and death in 75% of cases. Leukodepletion may improve prognosis. A therapeutic strategy based on leukodepletion and extracorporeal life support (ECLS) according to different thresholds of leucocytes has been proposed by Rowlands and colleagues.

Political ideology and health risk perceptions of food.

Rationale: Although food companies increasingly refer to moral values, such as patriotism and social justice, in their marketing efforts, little is known about how appealing to consumers' political leanings may affect food perceptions.

Objectives: Contributing to research on both consumer psychology and health risk communication, the current research addresses this issue and demonstrates how the use of incongruent political appeals decreases the effectiveness of food health claims.

Method And Results: Two experiments (N = 699; N = 702) conducted in the U.

New SPE-LC-MS/MS method for the simultaneous determination in urine of 22 metabolites of DEHP and alternative plasticizers from PVC medical devices.

DiEthylHexylPhthalate (DEHP) can leach out of plasticized PVC medical devices (MD) and may enter into contact with patients. This phthalate is known for its reprotoxic and endocrine disrupting effects. Its use in medical devices (MD) has been restricted and alternative plasticizers have been developed.

The rise and fall of dialects in northern elephant seals.

Vocal dialects are fundamental to our understanding of the transmission of social behaviours between individuals and populations, however few accounts trace this phenomenon among mammals over time. Northern elephant seals () provide a rare opportunity to examine the trajectory of dialects in a long-lived mammalian species. Dialects were first documented in the temporal patterns of the stereotyped vocal displays produced by breeding males at four sites in the North Pacific in 1968 and 1969, as the population recovered from extreme exploitation.

De-scenting Extinction: The Promise of De-extinction May Hasten Continuing Extinctions.

Among the most egregious and discouraging problems of conservation is the rapidly escalating human-caused species extinction rate. "De-extinction" refers to the application of certain cutting-edge techniques for the supposed recovery of lost species and gives the impression that scientists, enlightened and empowered by the miracles of technology, are coming to the rescue. "De-extinction" is the latest example of a long play of language that has given conservation efforts a tragically false sense of accomplishment and has worsened the conservation crisis.

Water Quality Is a Poor Predictor of Recreational Hotspots in England.

Maintaining and improving water quality is key to the protection and restoration of aquatic ecosystems, which provide important benefits to society. In Europe, the Water Framework Directive (WFD) defines water quality based on a set of biological, hydro-morphological and chemical targets, and aims to reach good quality conditions in all river bodies by the year 2027. While recently it has been argued that achieving these goals will deliver and enhance ecosystem services, in particular recreational services, there is little empirical evidence demonstrating so.

Impaired Presynaptic High-Affinity Choline Transporter Causes a Congenital Myasthenic Syndrome with Episodic Apnea.

The neuromuscular junction (NMJ) is one of the best-studied cholinergic synapses. Inherited defects of peripheral neurotransmission result in congenital myasthenic syndromes (CMSs), a clinically and genetically heterogeneous group of rare diseases with fluctuating fatigable muscle weakness as the clinical hallmark. Whole-exome sequencing and Sanger sequencing in six unrelated families identified compound heterozygous and homozygous mutations in SLC5A7 encoding the presynaptic sodium-dependent high-affinity choline transporter 1 (CHT), which is known to be mutated in one dominant form of distal motor neuronopathy (DHMN7A).

Kawasaki shock syndrome complicating a recurrence of Kawasaki disease.

We describe a case of recurrent Kawasaki disease (KD) in a non-Asian 6-year-old boy who had been diagnosed with typical KD without cardiac involvement at age 3 years. He was admitted to the PICU 3 years later for heart failure, hypotension, and deterioration of his general condition. Ultrasonography revealed left ventricular dysfunction with a 44% ejection fraction and grade I mitral valve failure without coronary artery involvement.

[Antimicrobial prophylaxis for caesarean delivery: changes in practice and administration before incision, feasibility study to paediatricians in Auvergne].

Objective: To describe the knowledge of paediatricians regarding the practice of antimicrobial prophylaxis for caesarean section in reference to the Consensus Conference of the French Society of Anesthesia and Intensive Care (SFAR) and assess the feasibility of a change in attitude (injection of the antibiotic prior to incision) among paediatricians Perinatal Health Network of Auvergne (RSPA) working in maternity.

Study Design: Cross sectional study by survey.

Methods: First questionnaire was sent to 46 RSPA paediatricians working in maternity.

[Favourable outcome after fetoscopic laser surgery for twin-twin transfusion syndrome: experience of an emerging centre].

Objectives: Our objective was to report perinatal outcome during the first three years of an emerging centre for laser photocoagulation in twin-twin transfusion syndrome (TTTS) and to compare with outcome observed earlier in the same centre when management consisted in recurrent amniodrainage.

Patients And Methods: We conducted a single centre retrospective study. We compared perinatal outcome of 19 consecutive cases of mid trimester TTTS managed by amniodrainage over a 10-year period with 49 cases of TTTS managed by laser photocoagulation over a 3-year period.

[A lethal variant of Netherton syndrome in a large inbred family].

Netherton syndrome is a rare autosomal recessive disorder characterized by the triad of ichthyosiform erythrodermia, typical hair dysplasia, and severe atopic features. The broad range of variable expression of this disease is well described and 20% of complications occur during the neonatal period such as hypernatremic dehydration, electrolyte imbalances, recurrent or severe infections, and failure to thrive. Mutation of the SPINK5 gene has been identified as disease-causing in Netherton syndrome, but the pathophysiology still remains unclear.

Fatal adenovirus infection in a neonate and transmission to health-care workers.

Background: Human adenovirus (HAdV) infections, while common in infancy and childhood, occur rarely in the neonatal period but may be fatal.

Objectives: To describe a transmission of HAdV from a patient with fatal pneumonia to heath-care workers that could be considered as a model of respiratory virus transmission in a care unit.

Study Design: Case report with virologic studies.

[Congenital lobar emphysema: a rare etiology of hyperechoic lung].

Lobar congenital emphysema is a rare pulmonary malformation corresponding to progressive overinflation of a pulmonary lobe secondary to partial bronchial obstruction. Prenatal diagnosis is mainly based on lung hyperechoic area. Sonographic features are not specific highlighting the interest of fetal MRI or postnatal tomodensitometry.

Mobilization of PCBs from blubber to blood in northern elephant seals (Mirounga angustirostris) during the post-weaning fast.

Northern elephant seals (Mirounga angustirostris) are characterized by extended fasting during which they rely entirely on their own body reserves. During fasts, lipids are mobilized from blubber to match the energy requirements of the animal. This transfer frees toxic fat-soluble pollutants into the blood circulation, which may exert adverse health effects, especially in young and developing animals.

Mating system and reproductive success in eastern Pacific harbour seals.

Harbour seals sometimes breed along inland travel corridors where females become clustered in space and time and males establish underwater acoustic display territories similar to terrestrial arenas known as resource-based leks. Under these conditions, we predicted that higher levels of polygyny would be observed than has been previously reported for this species mating in open coast environments without travel corridors. Reproductive success (RS) of 70 males was measured using 20 microsatellite DNA loci and likelihood-based paternity analysis of 136 offspring collected over 3 years.

Holocene elephant seal distribution implies warmer-than-present climate in the Ross Sea.

We show that southern elephant seal (Mirounga leonina) colonies existed proximate to the Ross Ice Shelf during the Holocene, well south of their core sub-Antarctic breeding and molting grounds. We propose that this was due to warming (including a previously unrecognized period from approximately 1,100 to 2,300 (14)C yr B.P.

[Neonatal morbidity after conservative management followed by systematic delivery at thirty-four weeks of gestation in preterm rupture of membranes].

Objective: To evaluate the neonatal morbidity and its risks factors in case of uncomplicated preterm rupture of membranes managed conservatively with subsequent planned delivery at 34 weeks of gestation.

Patients And Methods: We studied retrospectively 42 consecutive neonates systematically delivered at 34 weeks of gestation after more than 48 hours of conservative management for uncomplicated preterm rupture of membranes. Conservative management was conducted in a single tertiary care center and consisted in corticotherapy and in antibiotherapy (amoxycilline during 7 days).
