Background: Early onset neonatal sepsis due to salmonella spp is rare in developed countries. Vertical and horizontal transmissions were described, including faecal contamination of the birth canal. After a short incubation period, newborns may remain asymptomatic or present with sepsis or meningitis. Mortality rate as high as 58% were reported. Case Presentation Summary: We report a case of transplacental Salmonella Typhimurium infection in a premature infant. A mother with a one day history of fever and diarrhoea spontaneously delivered a premature boy at 35 weeks of gestation. On day 3, the infant presented with symptoms suggesting necrotizing enterocolitis: apnea, respiratory distress, feeding intolerance, bloody diarrhea and fever. Feeding were suspended and intravenous antibiotic therapy (ampicillin, amikacine and metronidazole) initiated. Laboratory data showed an inflammatory syndrome with elevated C-reactive proteine (71 mg/l), leukocytopenia (7270/mm3) and severe lymphopenia (580/mm3). Enterocolitis stage 1 (Bell classification) was diagnosed based on clinical and radiological evaluation. Salmonella spp were grown from the baby’s blood and stools and from the mother’s stools; the National Reference Center identified a Salmonella Typhimurium. Cerebrospinal fluid culture remained sterile. Clinical and biological evolutions were rapidly favourable with 14-days of cefotaxim IV. Maternal history revealed consumption of raw meat 3 days before delivery.Learning Points/Discussion: Salmonella spp should be considered in the differential diagnosis of early onset sepsis, particularly when mother presents gastrointestinal symptoms. Food safety education is crucial. The consumption of raw or uncooked meat during pregnancy should be avoided regardless toxoplasmosis immunization status. To avoid outbreaks in the neonatal ward (as reported in the literature), rapid detection and prompt institution of isolation and clustering measures are important. [less ▲]

The focus on outpatient follow-up of newborn infants increases as the duration of hospital stay after birth decreases. The first outpatient visit addresses the adequacy of the home transition. Appropriate feedings are checked. Sudden infant death syndrome prevention and security advices are reminded. Realisation of both neonatal dried blood screen and hearing test is confirmed, as well as planning of specific follow-up appointments. The physical exam will focus on red flags for diseases or malformations with a delayed presentation. [less ▲]

Because of the progressive loss of nigro-striatal dopaminergic terminals in Parkinson’s disease (PD), in vivo quantitative imaging of dopamine (DA) containing neurons in animal models of PD is of critical importance in the pre-clinical evaluation of highly awaited disease-modifying therapies. Among existing methods, the high sensitivity of positron emission tomography (PET) is attractive to achieve that goal. The aim of this study was to perform a quantitative comparison of brain images obtained in 6-hydroxydopamine (6-OHDA) lesioned rats using two dopaminergic PET radiotracers, namely [18F]fluoro-3,4-dihydroxyphenyl-L-alanine ([18F]FDOPA) and 6-[18F]fluoro-L-m-tyrosine ([18F]FMT). Because the imaging signal is theoretically less contaminated by metabolites, we hypothesized that the latter would show stronger relationship with behavioural and post-mortem measures of striatal dopaminergic deficiency. We used a within-subject design to measure striatal [18F]FMT and [18F]FDOPA uptake in eight partially lesioned, eight fully lesioned and ten sham-treated rats. Animals were pretreated with an L-aromatic amino acid decarboxylase (AADC) inhibitor. A catechol-O-methyl transferase inhibitor was also given before [18F]FDOPA PET. Quantitative estimates of striatal uptake were computed using conventional graphical Patlak method. Striatal dopaminergic deficiencies were measured with apomorphine-induced rotations and post-mortem striatal DA content. We observed a strong relationship between [18F]FMT and [18F]FDOPA estimates of decreased uptake in the denervated striatum using the tissue-derived uptake rate constant Kc. However, only [18F]FMT Kc succeeded to discriminate between the partial and the full 6-OHDA lesion and correlated well with the post-mortem striatal DA content. This study indicates that the [18F]FMT could be more sensitive, with respect of [18F]FDOPA, to investigate DA terminals loss in 6-OHDA rats, and open the way to in vivo AADC activity targeting in future investigations on progressive PD models.

Roof Stacking represents an approach to accommodate increasing population in the major cities around Europe, new agendas for urban densification emerge in response of finding sustainable solutions to use existing urban infrastructure in the most efficient ways. Several methods for urban densification are being proposed and seen in real life. One of those methods is roof stacking, which is defined as the added structure over the rooftop of an existing building to create one or more stories of living spaces. This report represents the results of conducted investigation on roof stacking method as a sustainable approach for urban densification. The aim of this report is to present a guideline for roof stacking construction approaches and methods and present the learned lessons through interviewing notable architects from different European countries who applied roof stacking. This report identifies the challenges and opportunities when applying roof stacking in addition to proposing recommended solution for the different obstacles that are faced when adding extensions on the rooftops.

We analyze the incentives of internet service providers (ISPs) to break net neutrality by excluding competing one-way essential complements, i.e. internet applications competing with their own products. A typical example is the exclusion of VoIP applications by telecom companies offering internet and voice services. A monopoly ISP may want to exclude a competing internet app if it is of inferior quality and the ISP cannot ask for a surcharge for its use. Competition between ISPs never leads to full app exclusion but it may lead to a fragmented internet where only one ISP offers the application. We show that, both in monopoly and duopoly, prohibiting the exclusion of the app and surcharges for its use does not always improve welfare. [less ▲]

Ecomorphology concerns the study of the relationships between functional design and the environmental constraints acting on organisms. It aims to understand how the morphological variations among species can be related to environmental factors and impact fitness. Having a large diversity both in their morphology and ecology, the cetacean taxa appears to be the ideal taxa to tackle the relationships between the locomotor system and way of life. Different studies have already showed that the number and shape of vertebrae in different cetaceans can reflect the stiffness of the body and consequently can impact their swimming mode. The aim of this study is to establish relationships between characteristics of the vertebral column of different cetaceans and their ecology. Meristic and morphometric data were collected on the vertebrae (centrum lengths, heights and widths, neural spine heights and transverse processes lengths) of species of odontocetes housed in different Natural History Museums in the world (AM-ULg, RBINS, MNHN, SMNS, NRM, Queensland, PEM, Iziko). Preliminary results show clear morphological variations between species at the level of the number and sizes of vertebrae. There is a clear relationship between body size and number of vertebrae except in Delphinidae. This family has an important higher vertebral count. These differences should be related to different swimming modes and reflect the different ecological behaviours of the studied cetaceans. [less ▲]
